1.1 Introduction

Within the literature of genre theory to date, there is scant reference to research on the 'genre' of email texts as the products of a discourse community. The word 'genre' has been loosely used to refer to the texts generated in email list forums for some time (e.g. Collot & Belmore 1996, Gruber 2000), but this thesis takes the position that the complexity arising from technological mediation of this form of written communication makes discourse oriented analysis of these types of text-unit problematic. This paper will argue that the texts instantiated by posts to a list are better regarded as representative of a macro-genre constituted by prototypical stages, and introduces a study which differs from many previous investigations of CMC discourse communities which have not considered email list texts per se, but have concentrated on ethnographic, action or linguistic approaches to analysis (e.g. Marshall 1999, Ekeblad 1998, 1999, Hård af Segerstad 2002, Ho 2002).

While Collot & Belmore (opcit) for example, maintain that there is no clear grammatical distinction between spoken and written forms of discourse, their study of CMC texts do not investigate the internal generic structure of the texts they selected, but conduct a Biberian style feature analysis of texts which have been classed as members of a genre a priori. This means that they have classed the products of such interaction as examples of a genre without specifying in what ways such texts represent a genre - and that therefore claims as to relative written-spokenness may not be applicable to notions of a CMC ‘genre’ in their study. My approach is rather to treat the analysis of these types of asynchronic interactive written discourse as somewhat problematic, and some of the issues raised by the nature of the texts -- for example, that these texts need to be regarded as more or less interactive (at 2nd order register), or more or less 'involved' (at 1st order register) rather than either written or spoken; and that the material context of situation, i.e. its technological mediation, allows and constrains the meanings which can be made in specific and identifiable patterns -- were addressed in Module Two, Part I [note 1] (hereafter Mod 2: I) of my thesis.

This thesis presented a framework or an approach for providing insights into the products and processes of written interaction from a genre perspective. In doing so, it represents an attempt to integrate a variety of approaches, rather than a focus on only one of the many possible orientations to the analysis of discourse. The model was developed in this way firstly because the texts on which the thesis is based incorporate features which have been analysed in the past using approaches developed for analysing either spoken or written discourse, and concentrating on those features which are therefore typically associated with registerial mode, due to their typical construction of the texts as interactive, or overtly dialogic. In Mod 2: 1 [note 1] of the thesis for example, I argued that a focus on features associated with mode (in terms of Hallidayan register which comprises three orders of discourse: field, tenor and mode: see for e.g. Halliday 1984) was inadequate for my purposes, since my primary concern is not with relative writtenness or spokenness of email as a mode of discourse. Rather, my use of the term ‘genre’ in this study and in the discussion which follows is tied to a notion of social purpose, and therefore the model needed to incorporate features related to inter-personal relations and to ideological meanings, as well as the textual meanings most commonly associated with mode and the degree of writtenness-spokenness in a text. Finally, and most importantly, this thesis approached the analysis and interpretation of generic staging - and discourse organisation in general - as a function of evaluation, and this paper will argue that such staging features an interrelationship of what Systemics (aka Functional Lingusitics, or Hallidayan grammatics) refers to as the four fundamental metafunctions of the lexicogrammar. Most approaches to text and discourse analysis on the other hand, concentrate on areas more narrowly focussed on cohesion (textual metafunction) and clause relations (logical metafunction). This means that my perspective incorporates discourse features usually considered under the interpersonal and experiential metafunctions as well.
 
In summary, this paper outlines a framework which recognises the insights of a variety of approaches to the analysis of both written and spoken discourse, and focuses on integrating these approaches within a genre perspective on the texts. The model of the texts developed was also largely dependent on analysis using approaches introduced in earlier parts of the thesis. Module 1 for example looked at the representation of 'social actors' in organising the argument and positioning audience members, and Module 2: I [note 1] I discussed positioning and status as revealed by appraisal analysis, together with the evaluative prosodies and rhetorical strategies writers use to help signal positioning, 'status', and text organisation. The remaining parts of the thesis were devoted to reporting on one perspective of textual interaction raised in the course of the research, and extending the use of the model for this purpose. Chapters 4 and 5 on poster identity[note 2] use the results of appraisal analysis to highlight some of the means by which three list participants ‘construct’ a textual identity. Chapter 4 outlined the relationship between textual identity and genre manipulation – or textual ‘style’ – and identity related to affiliation, or positioning of self (the writer/addresser) in relation to others and their values - what I term 'negotiated identity'. Chapter 5 reports on the results of the analysis, demonstrating ways in which the 'textual identity' of three selected posters can be distinguished. In terms of genre manipulation, texts of each poster are shown to use the resources of the list conventions in distinctive and 'identifiable' ways, while their use of these resources constructs a ‘persona’ aligned to particular ideological values, and as therefore affiliated or disaffiliated with specified 'others'.

In another part of the study, I undertook a closer look at the function of negative expressions in setting up evaluative units as part of a text's rhetorical organisation, particularly in the type of argumentative discourse common to these texts. The use of negation as part of the system of Engagement (introduced in Mod 2: II as part of the Appraisal framework) is implicated in the activating of invoked attitude. As discussed in Mod 2: II, invoked attitude tends to occurs in transition phases (Gregory 1985, c.f. discussion Mod 2: II) in the rhetorical organisation of these texts, commonly as an element of pre-closing units. Negative expressions may also realise one type of what I am terming 'markers' (Sinclair ref?) contributing to the signalling of either the internal organisation of units, or their boundary conditions.

1.1.1 Written interaction and the unit of analysis

Most written interaction is necessarily materially monologic, with no possibility of actual response reaching the original writer of a text. However, it is a commonplace in most language or literature research today to assert that all text is dialogic to some degree, because the writer takes the part of an Addresser (or narrator), and in this role, constructs through the text, a relationship to an Addressee (or Ideal/Imagined Reader). In addition, the extent to which the writer is able to make reference to other voices or positions as informing the writer's stance, results in texts which can be classed as more or less heteroglossic. In this sense, then, all written texts take up positions with respect to the projected voices and positions in other texts, both past and future, and through this means, writers respond to those voices already encountered, or to imagined responses to come. In choosing to study the texts produced in the interaction of a group of email list members, I was originally motivated by the fact that actual written responses are produced by members of the group. It was possible to study the way in which each participant made reference in their contributions to a variety of positions and voices, and in turn, how other participants made sense of these contributions via their own responses.
This paper then, is concerned with what  Hasan (Halliday & Hasan 1985: 63ff) calls the generic structure potential of the prototypical contributions to the interaction of the list - in what is known as a post. Exchanges between members of the group typically occur within posts, via strategies of formatting and other means of recontextualisation, and these fundamental framing conventions, while technologically prompted, are at the same time, developed and adopted by group members in particular ways in order that meanings be more coherently made. This means that turns are usually constructed within the post by the writer, sometimes interspersed with the 'interrupted' turns of another listmember's previous contribution (see for example Herring 2001: 619-20, who makes similar observations).

 Ex 1.1 below provides one example of this approach, what I term the overtly interactive post style (c.f. below 1.4.2 ), in which quoted material is commonly marked by carats (>):

Subject: Re: Spam - (And not the lunch meat)

Mike:
In response to your comments about spam, I must remind you that what I posted was written by the editor of the Red Rock Eater News Service. Those were not my words, but not far off my own opinions.

>First, let's differentiate between targeted ads and "spam."

No. Let's not. Spam in my mailbox is unrequested advertising. In certain cases I have volunteered to receive promotional material from a company (Some software companies offer updates on their stuff that I like to hear about.). I do not object to receiving this because I asked for it. However, if I order a book on Tibeten Rifle Shooting from amazon.com and then receive an advertisement from them about Tibeten Archery, it is spam, it is evil, and I don't like it.

>I operate a phone coaching service, and have no ethical problem with presenting it in newsgroups where it is relevant. For example, since I know quite a bit about weight-loss psychology, I put ads targeted precisely towards that end in an ng as alt.diet-support. I get the usual feedback to the effect that I am Evil.

You are. But that sort of evil is so common on unmoderated newsgroups that I have been driven from them completely. Not reading the newsgroups has pretty much solved the problem for me. My question has not to do with evil, but are you making any money?

>As I see it, targeted ads are not "spam."

As I see it they are and I will support legislation to stop it.

>"Spam" is, as I understand it, ads that are not precisely targeted to the unmoderated newsgroup or mailing list in question.
See above.

>(Moderated newsgroups or mailing lists exist at the behest of the owner or moderator...so they are in totally separate categories).

In the case of mailing lists, this is not really true. We at Netdynam are not moderated, yet I can kick people off and filter them so that they cannot resubscribe. In the case of someone repeatedly trying to sell a product here, I might very well do so. On Netd, of course, you would have the option of gathering enough support to get me unelected as listowner. On most unmoderated groups you don't even have that option.

>There should never be guilt in responding to targeted ads or to spammers.

Yes there should. Lots of it. (Notice we are trading pronouncements. Is that arguing, discussion or just posturing. Inquiring minds want to know.)

>If the cost is low to email, as Simon mentions, that is the joy of the Internet.

No, it's a curse upon the internet.
[...]

>We use them. Let us save
>our vitriol for the things in life that count.

I agree with this somewhat. I will choose the social battles I want to fight. I choose not to put much effort into this one. You might choose not to put much effort into trying to get homeless alcoholics off the booze. So we differ in where we do our community service. Nevertheless, I will encourage those fighting spam just as they would probably support me.
Methinks.

Thus, each post can either be considered to be one text - since they are each created and sent by one list-member in one chunk - or they can be considered to be comprised of a number of texts of varying types, resulting in a type of exchange complex, whose boundaries happen to be technologically signalled. In terms of Bakhtin's (1986: 72ff) discussion regarding the boundaries of the utterance, "changes in speaking subject" are clearly signalled within each post:

This change of speaking subjects, which creates clear-cut boundaries of the utterance, varies in nature and acquires different forms in the heterogeneous spheres of human activity and life, depending on the functions of language and on the conditions and situations of communication. (opcit)

However, in the case of the email post, the signals of these changes within posts are managed by the writer, mainly through formatting - a matter of control over the expression plane of mode - and thus the conditions and situations of communication can be regarded as providing for the interpolation of the Other as a case of 'manifest intertextuality' (Fairclough 1992: 117ff), rather than as a signal of the "finalization of the utterance" (Bakhtin: 76), which Bakhtin notes as one of the boundary conditions of a complete utterance. Therefore, following Bakhtin and others (c.f. for example, Stubbs 1996: 32), the complete utterance, or complete text-unit, is considered to be bounded by a change in 'creating' subject, as well as by the various signals of 'finalization' that posts typically employ (see below 1.6.2.1). Thus the post itself is considered as the primary text unit for analysis.

The model that I have developed looks at posts from both perspectives mentioned above: firstly, from that of the internal organisation of each of the basic discourse units (e.g. Turns, Stages, phases (or ‘Parts’); c.f. also discussion Mod 2: II) and the idea that each post may be comprised of a series of turns and shifts of register, and that writers will mark the boundaries of these text units using a variety of signals; and secondly, from the perspective of the post as complete utterance, as "primary text", one which makes reference to other texts and contributions in more or less overt ways, and locates itself in the context of an ongoing conversation:

Each individual utterance is a link in the chain of speech communion. It has clear-cut boundaries that are determined by the change of speech subjects (speakers), but within these boundaries the utterance, … reflects the speech process, others' utterances, and, above all, preceding links in the chain (sometimes close and sometimes—in areas of cultural communication—very distant). (Bakhtin 1986: 93)

My objective in developing this model is to account for the means by which posters adopt, and creatively reproduce, what I have previously referred to as the ‘group norms of interaction’ (Don 1997) by which members of the email list attempt to make their meanings intelligible to the other listmembers using only graphic channel means. My investigation is therefore concerned with:

…the uniqueness of process [which]is made intelligible by reference to the general regularities of a shared system familiar to the members of at least some specifiable social group.. (Hasan 1999: 223)

As argued in Mod 2: I[note 1], resources of the graphic channel (Hasan 1985) have not previously formed the main communicative means for group practices to develop via what Hasan terms ‘process sharing’ (opcit: 58). An email list provided a way of investigating features of process sharing in a written-only context, such as the way in which posters regularly incorporate the previous posts of other listmembers, the way in which posters stage their texts, and the ways in which attitudinal meanings functioned to both signal staging and to signal affiliation with respect to other listmembers. A further related objective was to reach conclusions about the ways in which posters creatively manipulate these norms of interaction as they set about constructing for themselves, by means of this communicatively restricted graphic channel, discursive identities or personas.

It is my position that ‘the post’ represents a type of speech genre, what Bakhtin (opcit: 78) refers to as the "relatively stable typical forms of the construction of the whole"(italics in original). A linguistic analysis of the representative texts in this study, and my active participation in the interaction of the list has allowed me to identify a number of ‘relatively stable typical forms of construction of whole posts’, and to note that listmembers use these forms as flexible templates or conventionalised social practices in which they manage their identities as textual personae. This aspect of textual identity, or what I term poster identity, is taken up in more detail under a discussion related to the regular stylistic features used by poster identities in the later sections (i.e. Chapters 4 & 5[note 2]) of the original thesis.

1.1.3 Rhetorical organisation potential

In describing the typical post, rather than adopt the term 'generic structure potential' mentioned above, instead, I use the term rhetorical organisation potential (first proposed in Module 2), for a number of reasons. The first relates to the applicability of the term rhetorical as an attribute of text organisation: most of the contributions to the group discussion forum I see as organised by argument in the service of identity maintenance. In other words, the social purpose of all of the contributions is to maintain identity - to explore difference and similarity (alignment/disalignment or affiliation/disaffiliation) with respect to others. The means by which list-members explore difference or construct solidarity is through argument, using a form of expository discourse - by positioning themselves and others in relation to ideological value systems, via reference to ideologically-charged tropes such as family, work, aesthetics, religion, gender, and so on. These types of text belong to the category of what Martin (1985) describes as expository writing, both hortatory and analytic, in which writers' social purpose is defined as persuading to and persuading that respectively (opcit: 17). In the service of these arguments, the use of evaluation and the evocation of attitude remains an obvious rhetorical device. In order to characterise the use of these rhetorical devices, I introduce a set of 'tenor variables' below in 1.3.1.1 (see Fig 1.1).

Secondly, rather than adopt the term 'structure', which has overtones of rigidity and obligatory elements, 'organisation' in this paper refers to a looser sequence of text events. It refers to a general tendency of posts to be sequenced, or ordered, in typical or conventional ways, which in turn allows for noticeable marked behaviour. This marked behaviour - when it occurs - tends to function as an overt signal of attitudinal stance - even if no explicit evaluative lexis is present due to the way conventions tend to set up expectancy of typical sequences: to break with convention is a means of calling attention to that act. Furthermore, while 'structure' connotes a somewhat static view of text creation and interpretation , 'organisation' allows for a more 'mutable' conception of a generic prototype, one which can accommodate recursivity, and transition phases or boundary conditions between stages or segments, rather than strict boundaries between the stages of any text (see for example Hunston 1989). As will be discussed again below, the relationship between the various stages or segments of texts, and the boundaries of the texts themselves, is conceived of as layered by frames of coherence (a term I first introduced in Don 1997: c.f. below 1.4), and these 'layers' can be partially accounted for by differences between constituency and dependency relations. In other words, 'coherence' in the context of an email post to a list can be described as a matter of embedding at one layer, and as a matter of reference and sequence at another. The conception of 'layering', 'framing', or 'tracks' owes much to the notion of metacommunicative, logical levels of analysis prevalent in cybernetics (c.f. Bateson 1972, Wilden 1980, Lemke 2000) and in Systemic Functional Linguistics (henceforth SFL) to account for the fact that features at one level of analysis contribute to meaning at the next level 'up', and rely on sequencing in order that these meanings be made and interpreted. It also owes its conception to the work of Goffman (1981), particularly his notion of footing, referred to again below (1.4.1). These perspectives can be used both to account for texts as organised wholes after the event, or as sequences of textual events which make their meaning by reference to ever wider intra- and intertextual chains from a more dynamic perspective of text as utterance (or reading event) . From this perspective as well, insights into the nature of the "reading event" provided by Sinclair and others (e.g.1993, Hunston 1989, 2000, Francis 1994) - particularly the notion of the signalling of coherence on both the autonomous and interactive planes of discourse have influenced my investigation into how both reference and discourse markers (analogous to signals of Engagement under the appraisal framework) contribute to the articulation of a text's organisation. Bhatia (2004) also outlines a view of genre in which the description of genre can be 'characterized at various levels of generalization' (p. 59), and his approach can be usefully compared with the one adopted in this paper. Both these approaches are discussed again below. 

1.2 Genre and written interactive texts

1.2.1 Perspectives on genre

The use of the term 'genre' appears problematic for discourse analysis, and particularly for the data I use for several reasons. The notion of genre has been widely used as a term to cover a range of linguistic entities in both literature and language studies during the past decades, including that of email interaction (c.f. Gruber 2000). It has been adopted to account for the unfolding of text types in SFL in particular, and linked in this regard to the nature of the social purpose for which the text was created (see for example Martin 1985, 1992, 1997, Christie & Martin 1997, Eggins & Martin 1997, Martin & Veel 1998). At the same time, the use of the term 'genre' is itself contested within SFL and some scholars, notably Hasan (1995, 1999), argue strongly that the term should be used to refer to "text types" rather than to a separate level of discourse function, in contrast to Martin (op cit) and others who prefer to conceive of genre as a separate discourse level subsuming Register. Its use in systemics in general seems partly reflected in Bakhtin's use of the term, particularly as presented in the translation of a collection of his later works (opcit 1986, and under the name Voloshinov 1986). At the same time, Martin's conception of genre in SFL can be traced mainly to Labov's (1992, Ch 9) work on narrative (see also Bamberg (ed) 1997), while Hasan's use of the concept can be traced to the work of the Firthian linguist, Mitchell (1957, cited in Eggins & Slade 1997). The use of the term 'genre' is also prevalent in folkloristics and ethnomethodology (e.g. Briggs & Bauman 1992, Hanks 2000), as well as literacy pedagogy (e.g. Christie and Martin 1997, Martin 1985, Dudley-Evans 1986, 1997, Freedman & Medway (eds) 1994, Swales 1990, Hyland 2000, Lewin et al 2001, Burns & Coffin (eds) 2001, Bhatia 2004, Ravelli and Ellis (eds) 2004, Lewin, Fine and Young 2001), and many linguists and researchers alike use it as a term of pre-theoretical convenience (e.g. Biber 1988). This chapter uses the theoretical notion of genre in the process of outlining the framework for analysing written interaction based on the analysis of texts produced in a specific mailing list. This is because the description of the organisation of email posts at first glance suggests that they could be classed as forming a type of genre, but I would prefer to retain the term genre (or more specifically, core-genre) - what Bhatia (opcit) refers to as generic value, and Bakhtin as primary speech genre - to refer to more regular, abstract cases of textual organisation, and in this sense, my use of the term follows that of Martin (1985, 1997). Because the main tools of analysis I use are informed by SFL, reference to genre in this thesis will assume this theoretical perspective. In addition, I have also used approaches which do not explicitly make reference to 'genre', such as that of Goffman (1974, 1981) in order to provide another perspective for analysing and interpreting the data used. 

1.2.2 Genre, texture, ideology, and rhetorical organisation potential

Fundamentally, I view 'genre' as a function of the dynamics of its texturing (Fairclough 2003: 100ff), and thus it can both account for, and take into account the legitimated options for action that any participant can undertake at any given juncture of the unfolding of the discourse. In a similar fashion, genre figures in what SFL treats as a realisation relationship - with "the ways in which field, mode and tenor variables are phased together in a text" (Martin 1997: 12). This view of texturing I see as analogous with my own term rhetorical organisation potential (ROP) which, as acknowledged above, makes reference to Hasan's (1985) term generic structure potential. In the case of specific institutional practices, which include the activity-sequences legitimated within a 'community of practice' (Lave & Wenger 1991, Eckert & McConnell-Ginet 1998), the conceptualisation of genre is put at risk by issues relating to mode, and some of these were addressed in Mod 2: I. Therefore, 'genre' needs to be characterised at a variety of levels of delicacy by reference to both linguistic (synoptic) and discursive (dynamic) orientations, which take into account the development or contestation of the norms of the group's discursive practices over time. While this view of genre is not necessarily new (e.g. Miller 1994, Bhatia 2004), the application and integration of this view in analysing the discourse of communities of practice - outside academic and commercial discourse communities at least - has not been developed to any great extent (recent work on pedagogical contexts e.g. Coffin, Painter and Hewings 2005 an exception). On the other hand, while not specifically genre-related, Ho's 2002 work represents an in-depth study of website mediated communication, what she terms electronic discussion forums (EDF), and many of the areas of investigation in her study parallel areas of concern in this thesis. Ho distinguishes between the various forms and approaches to the study of this type of discourse, and goes on to examine in detail the nature of the discourse evident in the EDF in which she was involved. Her work focussed in particular on the construction of a particular Singaporean identity within the texts in her study. Using a slightly different perspective, Hård af Segerstad (2003) analysed in detail the features of email mediated communication discourse in the context of an overview of several other forms of CMC discourse. Both works provide detailed surveys on the literature addressing analysis of CMC texts, and therefore such a review is not attempted here. However, while both of these works address areas of similar concern to that of this thesis, they do not focus on the development of an approach and a model which may be adapted to the investigation of generic conventions of a wide range of written interactive texts. As Ho (opcit: 30) observes:

The specifics of how discourse features and linguistic devices function to fulfil particular roles within specific contexts in the dynamic, interactive environment of online communication, however, does not seem to have received [comparable] attention.

The aim of this thesis therefore is to contribute to this research with a particular emphasis on the organisation of a social community's prototypical text-units, where I pay special attention to the ways in which attitudinal meanings appear at regular intervals and thus help to signal staging in texts (for which I have adopted the term ‘attitudinal prosodies’). This leads in turn to the specification of what I am calling its rhetorical organisation potential.

1.2.3 Genre and the post as the unit of analysis

In describing the fundamental unit of analysis in my study, the post, I have adopted the term macro-genre to refer to the 'relatively stable typical forms of the whole utterance' (Bakhtin 1986: 78), signalling that the actual 'content' of any post may be comprised of any number of core-genres such as narrative, recount, exposition, and so on. In the context of this thesis, 'macro-genre' refers to texts which incorporate what Fairclough (2003: 69) refers to as "the socially available resource of genres in potentially quite complex and creative ways." Core-genres, in contrast, are resources at an abstract level of linguistic and social organisation, recognisable by a wider range of community members than the institutional or community group which develops its local conventions of practice, and which lead to the development and negotiation of macro-genres in the sense I am using the term here. Couture (1986: 82, quoted in Swales 1990: 41) provides one fundamental definition for the analysis of [macro]genre which accords with the approach taken in this thesis: "[genre] specifies conditions for beginning, continuing, and ending a text".
Eggins and Martin (1997: 236) represent the notion of a [core]genre as "the way the types of meaning in a text co-occur [is] a pattern typical of a particular genre", and continue "the sequence of functionally distinct stages or steps through which [a text] unfolds". They note that "linguistic definitions of genre [identify] 'relatively stable types' of interactive utterances [and] define genres functionally in terms of their social purpose" (ibid).
Martin elsewhere (1997) describes the functional parameters of genres more precisely, and in doing so paradoxically acknowledges that the boundaries between genre 'types' are not precise, and that genres are better located in a topology, rather than a typology. What this means, is that "core genres" can be recognised within texts which are of completely different types, if, for example, mode is the variable - as I am proposing here.

1.2.4 Genre identification and genre users

In order to locate the recognition criteria for genres in the actions of participants, rather than the nature of the texts themselves, Swales proposes the notion of a discourse community which he defines by means of 6 characteristics (1990: 24-27). The mailing list under investigation would appear to fit the definition, and with reference to the notion of the negotiation of macro-genres posited above, his criterion 4 seems especially relevant: "newly-emergent groupings [need] to settle down and work out their communicative proceedings before they can be recognized as discourse communities. If [a new group] 'borrows' genres from other discourse communities, such borrowings have to be assimilated."
Bhatia (2004: 149) however, contrasts the notion of discourse community with that of community of practice. He makes the distinction between the texts and genres that enable the community to maintain their communicative purposes for 'discourse communities', and the values and practices which hold a community together for 'communities of practice'. In Module 2: I the term 'community of practice' was adopted in order to describe the texts analysed as products of the practices of the email list participants, and for the same reason, in Don 97: 2.2-2.7 the activities of the list were described in terms of Halliday's (1985: 44ff) levels of context. This is because prototypical texts need to be considered as a part of the wider social contexts within which they function as units of meaning.
At the same time, Bhatia's (ibid) criteria problematise the categorisation of the products of this online group, since these products appear to be classifiable under the two types of community he distinguishes and noted above. For this reason, following Bhatia, (macro)genre users have been re-classed as members of a discourse community rather than a community of practice, especially since members of any discourse community can also be members of other discourse communities by virtue of their control (c.f. Figure 1.1 below) of a variety of (macro)genres, while being at the same time, members of different communities of practice depending on their participation and recognition in that community. Furthermore, with respect to the email group in this study, while many long-term members are affiliated by the values and the practices of interaction developed within the group over time,  they each also belong to widely differing (cultural, ethnic and national) communities and hold widely different values on many issues. Therefore, the classification of participants as members of a discourse community acknowledges that it is the products (i.e.'texts') of this group that are the focus of this study, rather than the participants themselves, even when their 'textual identity' becomes a means for distinguishing between them in Chapters 4 and 5[note 2].

These factors have led to the term 'macro-genre' being chosen to refer to the prototypical text-units of this email-mediated discourse community as it acknowledges their status as 'generalisation', and distinguishes them from objects known by such terms as idealisation, universal template, schema, etc.
In terms of the levels of generalisation outlined by Bhatia (2004) the term macro-genre which I use in this thesis is differentiated from his notion of genre colony by its derivation from both analysis of products (texts), and my participation as a member of the community of practice/discourse community who uses this means of communication.

Because the identification of genre is contested in the literature, and complicated by the appearance of genres in a variety of mediated forms, the next section addresses some of the issues relating to mode and genre in more detail.

1.3 Issues of genre, text-type, and mode

1.3.1 Identifying boundaries of text segments with reference to context

Hasan (1999: 253ff) discusses at great length the problem of identifying the boundaries of stages within any text, and relates this to the interface between register and context as it is conceptualised in SFL. If register is the textual realisation of Context of Situation, then any change in register, whether it be of field, tenor or mode, also signals a shift of context, and hence engenders an internal text boundary. In Mod 2: II, this type of shift was also discussed by reference to Gregory's (1985) conception of texts being articulated by phases, which correspond to changes in context signalled by changes in register, and is supported by Cloran's (1994, 1995, 1999) work on the conceptualisation of context within SFL. For Hasan, one of the problems attending the notion of genre concerns the identification of boundaries or stages in text structure, and relates to the location of what SFL refers to as rhetorical mode, and whether it is related to a specific register variable - field, tenor, or mode.


As stated above, the definition of core-genre adopted by Martin and others within SFL, incorporates the notion of social purpose - for example, to persuade, to report, to explain, and so on - but traditionally, within Systemics, this aspect of a text's functionality has been subsumed under rhetorical mode, or 'the part language is playing', along a continuum of ancillary - constitutive (referred to again in the following section). Thus, rhetorical mode has lately been considered as helping to construe mode due to its reference to the material activity which accompanies the ancillary, whereas Hasan (1999) argues that the feature 'social purpose' attending rhetorical mode reinforces her contention that it remain a matter of field. Martin and others regard 'social purpose' as helping define a level of discourse realised by register (i.e. genre in Martin's conception), at a different level of abstraction. For Hasan, this provides for problematic contradiction within SFL. At the same time, if genre - whether core or macro - is conceived of as a level of abstraction realised by a variety of layers or tracks interrelated to signal shifts rather than strictly demarcated boundaries - as between stages in a text - then such contradiction might be seen instead as part of the normal flexibility of language.
Section 1.4.2 below outlines this notion of over-layering of tracks in more detail, arguing that such layers can be attended to in turn by the analyst in order to look at a number of ways that writers organise their discourse. Over-laying is not necessarily done consciously, but writers must be somewhat aware that incorporating a degree of redundancy of coherence markers on several tracks (especially in such a mode sometimes described as written 'conversation') will lead to greater 'uptake of illocutionary force'. 'Purpose' or goal in this view is not located in the intention of the individual writer, but in the wider social goals that genres have developed to serve. Genre is therefore an abstraction, incorporating the idea that over-layering contributes to a another level of text organisation, which is not merely a combination of sequenced types of registers, and which may conceivably appear within a number of different 'text-types' as outlined below. Before returning to the specification of the features of these tracks or layers in the texts, in the following sections I discuss distinctions of register, genre and text-type in a little more detail.

1.3.1.1 Distinctions of register and genre

This sub-section addresses the way in which patterns of co-occurrence of textual, interpersonal and experiential values relate to notions of register and genre with attention to Hasan's arguments (in particular 1995 and 1999) that register alone can account for such patterning.
Hasan’s argument referred to in the previous section, suggests that the practice within SFL of describing one aspect of a "contextual configuration" (Hasan 1985: 55ff) by reference to a continuum which treats verbal action as a matter of [ancillary] v. [constitutive] mode (1999) would be better seen as part of the system of field, which is "concerned with specifying the nature of social activity" in which both verbal and material actions are implicated (Hasan 1999: 282). My claim is that the texts in my study are entirely constitutive of their context, but whether this constitutiveness relates to their field or their mode appears to be at issue. For me, this problem is intimately related to the argument over whether we can classify sets of texts as realising 'genre's or whether, as Hasan maintains, SFL's conception of rhetorical mode as an aspect of field is sufficient to account for the development of 'argument', or the 'relatively stable forms of organisation' in texts which might signal that they were related. She argues that examples of 'verbal action' such as "defining, explaining, generalising, narrating, lecturing, persuading…" (opcit: 276) are accounted for by field (rather than genre), and goes on to state that mode is better viewed as limited to matters of contact (opcit: 282), or what I have been referring to as relative interactivity (see discussion Mod 2: I[note 1]). The definition of 'contact' as a system relating to degree of involvement construing tenor in SFL (see Martin 1992: 528ff, Poynton 1985: 77) is thus also thrown into question, but has to do with Hasan's conception of 'contact' as applying to "activities which just cannot be performed with verbal action ALONE: they call for material action" (opcit: 276, emphasis in original).

In Mod 2: I[note 1], I outlined a set of dimensions along which stretches of email text(s) could be located in terms of mode, and argued that the description offered could be encompassed by the notion of "relative interactivity". As mentioned above, this term refers to phenomena similar to Hasan's (1999: 282) use of the term "degree of immediate contact", so Hasan uses the term ‘contact’ in a different way from Poynton and myself, and this needs to be made clear for the purposes of the following discussion.
In Mod 2: I, I argued that, since the context for email list interaction was in some senses entirely constitutive of itself, i.e. the written contributions are the context, then the issue of the constitutive-ancillary dimension was rendered somewhat irrelevant for the description of mode in that context. This means that the fact that these texts were originally transmitted and responded to in email, has nothing to do with their rhetorical mode, and hence is not related to their field. On the other hand, Hasan maintains that because the purpose or goal of a speaking or writing act may be described by reference to rhetorical mode, and since this concerns the nature of the verbal activity (i.e. field), there is no need to posit a separate level of discourse called genre which purports to do the same thing. I return to this point again in section 1.3.2 below when a distinction between genre and text-type is proposed. Meanwhile, the next section addresses the notion of contact/familiarity referred to above in order to clarify its use in descriptions of tenor, rather than mode.

1.3.1.2 Variables of tenor and distinctions of register and genre

Figure 1.1 below, based on Poynton (1985), outlines a set of tenor dimensions as resources for construing dis/alignment and dis/affiliation in terms of skills, knowledge, common assumptions, shared values and so on.


Figure 1.1: Tenor variables for construing writer - reader alignment and affiliation

For convenience, I have grouped these 'variables' into categories based on dimensions originally proposed by Poynton (opcit), in order to illustrate resources that writers use in negotiating identity - or rather, one of the resources that discourse analysts may use to make accounts of such positioning practices. I present them here because my discussion needs to make reference to a variety of these 'tenor dimensions', both as a means of discussing strategies that construe positioning, and hence the negotiation (over time) of 'identity' pertaining both to writer/speaker and members of the projected audience, and as highlighting the function of tenor in realising the rhetorical organisation potential of texts. These tenor dimensions and their means of activation (such as 'amplification') are discussed and exemplified in more detail in Chapter 3[note 2] where the notion of textual identity is explored. In addtion, the derivation of the macro-genre itself incorporates realisations of tenor, and these can be described by reference to subsystems of appraisal - Engagement, Attitude and Graduation - which are in turn dependent on the interrelation of all lexico-grammatical metafunctions.

The conception of contact as a variable of tenor within SFL can also be shown to redound with features relating to field. For example, consider the principle of contraction (Fig 1.1 above), in which

..the extent of contact is realised in terms of proliferation, or the range of options available. Generally the greater the contact, the larger the range of options, and the less the contact, the smaller the range (to the point where fleeting contacts with strangers or people one barely knows are commonly quite ritualised, hence small-talk about the weather…(Poynton 1985: 80)

The degree of contact will also determine the relative degree to which "the realisation of the meanings selected has to be more [or less] explicit" (Martin 1992: 531). This principle appears to parallel the principle of 'specialisation' within accounts of field: ‘specialised' lexis is generally a feature of specific fields of discourse, but such specialisation can only be used when the tenor of the register - i.e. the positioning of ideal readers - assumes high involvement: "the higher the degree of involvement […] the more exclusive the semiosis" (Martin: ibid). Consider an instance when the topic discussed enters a field where expert [status: authority] (c.f. above Fig 1.1) is required; in order that use of specialised lexis does not enact a communicative obstacle, the positioning of ideal readers must also be one of high [contact: involvement] - in other words the principle of reciprocity is assumed because speakers need not explain their specialist terms in detail. This may have the effect of closing off communication to those not familiar with the jargon or 'exclusive' lexis employed by members of a particular group. In other words, I am arguing that specialist lexis construes a particular field (perhaps an expert one) and that such a field implicates a particular tenor relationship (one of some significant degree of shared knowledge, that is to say, of involvement). On the other hand, interlocutors could have a similar knowledge of an ‘expert’ field while being entirely non-reciprocal in terms the other resources they have available. In this sense, while ‘specialisation’ relates only to one, relatively narrow aspect of tenor, and not to other aspects of ‘contact’ or ‘solidarity’, it nevertheless highlights the nature of the interrelationship between features of register and context.
My representation of tenor variables in Figure 1.1 does not make reference to the subsystems of CONTACT outlined in Poynton's original (opcit: 77) for reasons discussed in Mod 2: I[note 1], section 2.1 pertaining to levels of abstraction and different orders of register. I would maintain that the interpersonal discourse semantic is a textual construct, not a description of 'material situational setting' as Hasan calls it, nor context of culture. Such factors influence the production and reception of a text and its meanings, but cannot be 'read off' any text. This point is entailed in the next section 1.3.4 when a distinction between 'genre' and 'text-type' is proposed.

In summary, any description of the tenor of the text also relies on a concurrent description of their realisations in field and mode. Issues of co-positioning and how they may be accounted for present problems for the analyst when looking at lexicogrammatical realisations of tenor, since this process of inter-subjective co-positioning in turn appears to be dependent to some extent on resources associated with both field and mode at the same time, which has been hinted at in the previous discussion. Thus, tenor cannot be analysed independently using the resources typically associated within SFL with the interpersonal metafunction alone. My analysis indicates that the realisation of inter-subjective co-positioning relationships (a matter related to the text’s tenor) is not solely achieved via interpersonal meanings, but that textual, experiential and logico-semantic meanings are also implicated. Halliday has allowed for this idea, and it is supported by arguments made by Thompson, especially1999. 

For similar reasons, I maintain that the appraisal framework cannot be defined as a system of resources pertinent only to interpersonal metafunctional realisations. Many of the categories of appraisal are realised by a combination of linguistic resources and strategies (see for example categories of invoked attitude, Figure 1.2 below) which represent a range of metafunctional resources. Instead of locating appraisal within tenor, therefore, it would be better viewed as a system of classification that describes evaluation in general, a system located at a level constrained by and ranging across the resources of register: the discourse semantic. For this reason, appraisal can be a valuable means of revealing rhetorical prosodies in any text which are built up by positioning moves. Such prosodies are one means for tracing the development of each text's organisation. The proposed prototypical staging of the texts in my study have relied to some extent on attempting to track such prosodies via attitude analysis, particularly invoked attitude.

1.3.2 Text-type construed by mode

In this section I outline reasons for proposing that the term text-type be applied to texts defined by reference to the materiality of their mediation, i.e. their production, distribution and reception, leaving the term genre to be determined by features other than mode, or other than by field alone. Just as the register variable field is foregrounded in the construal of genre (as suggested by Hasan's 1999 argument), the register variable mode is foregrounded in the construal of text-type. This does not suggest that a description of genre is exhausted by reference to field, just as a description of text-type is not exhausted by reference to features of mode. Moreover, a description of text-type in the sense I am advocating here refers to features outside the verbal text itself and therefore cannot be synonymous with mode, and in the same way, a description of genre is not synonymous with register, let alone any one aspect of it. On the other hand, it does provide means for a distinction between a genre such as 'hard news report', and the text-type of its 'utterance' such as newspaper, radio bulletin or web page. A song may be recorded in the studio, and then reproduced and distributed on vinyl, CD or tape. Its eventual transmission and reception may have a variety of actual contexts, but typically the text's utterance is going to be constitutive of its verbal action, with channel phonic and medium 'spoken'. Similarly, the core-genre 'exposition' encompasses a great variety of sub-genres, one of which is the academic discourse act - such as lecture, presentation, examination submission or dissertation. The social purpose of exposition may be glossed as persuading or arguing. With this in mind, it can be seen that a variety of text-types may be represented by the rhetorical mode activity of 'persuading', and that the social purpose pertaining to argument and persuasion may be realised by a great variety of generic sub-categories. The distinction proposed here is aimed to obviate the confusion of genre and text-type.


The corollary of my distinction with regard to email texts is that mode is construed by the textual realisation of the actual technological mediation in which the texts were both created and distributed. Thus, 'email post' and '[various formatted] styles of email post' would be labels pertinent to text-type, while their 'content', or 'social purpose', would defined by reference to conventionalised staging - their argument and social purpose as revealed in the meanings they each make - as a macro-genre, which in turn, might incorporate as many culturally-conventional, abstract core-genres as was available to each email-using discourse community. It can be easily recognised that the actual textual realisation of such macro-genres would not be theoretically restricted to email - there is nothing to stop such macro-genres from appearing in any material form. In other words, the constraints of the technological mediation tend to promote such textual realisations in interaction, rather than to produce them.

1.3.3 Macro-genre construed by rhetorical organisation potential

Therefore, to restate the observation made earlier, this thesis regards genre as a function of texturing, which in turn, I argue has as much to do with the resources construing tenor as with those which construe field, and this approach means that the nature of the rhetorical positioning developed within each text is based on the deployment of the resources of the interpersonal as well as the ideational (experiential and logical) metafunction in texturing, and hence organising the argument of the text. In addition, the mode, construed by features of formatting described in Mod 2: I in tandem with lexico-grammatical resources such as thematic development also figure in the texturing of a text, and hence its generic organisation. 

Thus, the use of evaluative positioning, and strategies relating to signalling alignment (related to Goffman's 'footing' discussed in more detail below 1.4.1) are relevant for the analysis of the rhetorical organisation of any text, and in hypothesising from examples the rhetorical organisation potential of such texts in general - specifically, the prototypical macro-genres associated with particular institutionalised activity sequences (Martin 1992: 537ff) - from any community of practice studied. In Mod 1[note 3], for example, I argued that resources usually seen as construing that part of register known as field - the representation of social actors and their relative agency as construed by the resources of the transitivity system in SFL - should also be considered as contributing to the positioning of audience and the organisation of the text's arguments, and hence the tenor of the text. From the perspective of the metafunctional resources which realise field, tenor and mode, it might seem as if the textual and logical metafunctions would be more heavily implicated in creating texture - and hence in construing the mode and text-type of any text, but this paper takes the position that while mode is a defining feature of text-type, and that the resources of the textual and logical metafunctional construe mode, interpersonal and experiential meanings are just as defining of the texture of any text, and that texture in this sense is more constitutive of 'genre' than of 'text-type'.

1.3.3.1 The conception of genre and written interactive discourse

One recent study of the textuality of email messages (Gruber, opcit) used the notion of 'genre' in order to present a clear description of the nature of 'scholarly e-mail messages' in terms of their use of theme and intertextuality. This indicates that Gruber also regards activity-type and field as foregrounded in the construal of genre. Although the article remarked on the interpersonal metafunctional features of the texts, within the scope of his report it was necessary to focus on a limited range features in order to demonstrate its claims, and so it provided little support for my own contention regarding the significance of the resources of tenor. However, as stated earlier, I prefer to reserve the term genre, or core-genre, for more abstract texturing conventions, and to employ the label macro-genre for institutionalised and typical arrangements of text events via the use of 'rhetorical organisation potential' which is realised in a prototypical macro-genre.
The notion of genre adopted by Gruber (op cit) owes its conceptualisation to Fairclough (1992) and differs slightly from that proposed by Martin (1992) although the two are related. Like Gruber, the approach that I use is dependent on the insights of both Critical Discourse Analysis (CDA) including the work of Fairclough, as well as SFL, particularly the work of J. R. Martin and Ruqaiya Hasan - despite their differences over the definition of genre. Another prominent genre analyst, Bhatia (2004: 60), conceives of what I am calling core-genre as generic values, preferring this term due to what he claims as a lack of 'any specific textual sequencing' of rhetorical acts. I maintain that such core-genres do have recognisable sequencing, and that many of them are incorporated into the macro-generic organisation of email posts as interdiscursive elements, their inclusion signalling an assumption that the audience will recognise their core-generic status (see for example texts [jvs84.20/rob] and [jvs228.56/stan] which employ narrative and limerick sequences respectively


In the following section, the relationship of 'generic staging' to local norms or conventions is discussed, and the issue of the identification of the boundaries of text-units is addressed once more, with reference to the theoretical perspectives already introduced above.

1.4 Norms, Conventions, and Frames of Coherence

1.4.1

In Don 1997 I proposed that this email-mediated group of interactants or discourse community (the term I favoured then was derived from Hymes' 1974 notion of speech community) could be described and interpreted using a set of 'frames of coherence', which I saw as cues or signals operating at a variety of discursive levels in the texts which realised its context. This thesis takes up the same notion of frames of coherence, and uses it to describe a model developed by analysis and participant-observation which identifies the typical patterns of generic staging within the specific written community under focus. I propose that this model also has a more general application for investigating interactive written discourse, and for developing prototypes for other discourse communities. The framework provides a means for accounting for the social practices of a specific 'speech community' (and other related email-mediated groups) characterised by their development of a set of norms or conventions, and the means by which members signal alignment, or footing in Goffman's terms (1981: 128ff):

The bracketing of a 'higher level' phase or episode of interaction is commonly involved, the new footing having a liminal role, serving as a buffer between two more substantially sustained episodes.

In the above quotation, Goffman makes reference to a liminal role, which is involved in signalling higher level interaction. In the framework I have developed, it is the notion of layers at different levels of abstraction to which the term 'frames of coherence' refers. At each layer, framing operates via signals or cues which are used by writers to indicate, and by readers or analysts to interpret the changes in footing which may indicate boundary conditions of the generic stages of a typical contribution to interaction. As indicated above, as well as the notion of footing, framing also refers to another insight of Goffman's (1974: 210ff ), that 'directional cues', or metalinguistic signals (Hanks 2000:177), take place in a variety of 'tracks', 'channels' or 'layers' in any text. It is in the complex over-laying of these tracks that the framing and hence organisation of argument and positioning of any post/text is accomplished. For this reason, part of the analysis of texts in this study concentrated on what I have termed "markers" at Layer Three (see below 1.5.4). These markers subsumed those elements in a discourse which signal conjunction or comment on the unfolding of the discourse in any way.

Each group, whether it is conceived of as a community of practice or discourse community, develops its own conventions for framing their contributions at each layer or track of interaction, and participation in a written speech community mediated by email is therefore no different in this respect than in any other mode of interaction. In other words, as argued earlier, once text-type is held constant, the matter of speech genre in Bakhtin's (opcit) terms, becomes more relevant for determining how the conventions of any group have developed in order to legitimate their practices, and control identity. For this reason, parts of the thesis used findings based on the main list in the study, for comparison with findings using excerpts from the interaction of another similar list.

The specific written community which provided the main source of data for this study, was introduced in Modules 1 and 2: the textual activities of a specific email discussion list and its members. In one sense, this thesis was conceived of as a case study of some of the norms of interaction which have become apparent during the course of the list’s history, and which ‘realise’ its context. However, the underlying aim of the research was to develop a reliable and sturdy model with which to approach other types of text, and similarly account for their interactive, dynamic orientation, or the nature of their dialogicality.

1.4.2 The Layering of frames in email posts

Identification of text-units, or units of analysis, is one of the fundamental issues in text analysis - and most especially in the texts created in this mode of interaction due mainly to the multi-logical nature of participation. (c.f. Mod 2: I [note 1]).
As indicated above, it is the nature of the signalling of (sub)text boundaries which indicate the staging of any text and hence its internal organisation - as well its relationship to other texts. What constitutes the boundary of any text/speech event (e.g. turns, stages, or phases) in this mode, I characterise as a matter of both level of abstraction, and the signalling or reading (or both) of sequencing in a variety of ways. By ‘level of abstraction’ I mean that I determine boundary conditions by means of observing ‘interference patterns’ when features observed at a variety of Layers are overlaid. For example, units may be formed by the types of relation outlined in Hoey (2001 referring to Winter's work), such as sequence (or logical), and matching relations. One way in which such matching relations are signalled is through negation. 

Hunston's (1989) analysis of her corpus of scientific articles addresses the same issues as those tackled here, namely that evaluation and rhetorical positioning are the main elements which help organise a text: "…evaluation organises all the meanings in the text into a coherent entity" (opcit: 71). Her thesis involves analysis of moves which signal text structure by looking at features on three main dimensions: Status, Value, and Relevance. Because the texts she examined are members of the core-genre [expository: analytic] in Martin's (1987) terms, the three dimensions she identifies could also be applied to the texts examined here since many of them incorporate an expository core-generic orientation. However, because the register, and in particular the field and mode of discourse of our samples differ, the nature of the evaluative strategies differ also. The use of the appraisal framework for this thesis also means that the perspective on the use of evaluation differs. While appraisal (see Mod 2, Part II ) looks at types of attitude and means of engagement separately, Hunston's model (opcit) groups such indicators of each dimension together. Furthermore, because the targets of evaluation in Hunston's texts were non-animate, certain types of attitude under appraisal - such as those pertaining to human behaviour and emotion (Judgement and Affect) would not be relevant for her texts. Many of the evaluative resources in Hunston's texts would be classified as subcategories of Appreciation under appraisal, while identification of features via sub-dimensions of Status, Value, and Relevance would be attended to as systems of Engagement under appraisal. At the same time, my study examined linguistic resources which also appear in Hunston's framework such as markers, and the notion of prospection . These resources help signal both evaluative orientation, and text unit boundaries.

Some of the means for determining text boundaries at what I am calling 'Layer 1' (c.f. 1.5.2 below) were presented and discussed in Module 2: I. The framework presented here relies on this earlier discussion, in particular the description of 4 fundamental styles of text formatting, and the 3 dimensions of analysis constrained or enabled by the technological mediation of the texts (Mod 2: I, section 3.3 [note 1]). In this sense, frames of coherence can be seen most clearly as functioning to re-contextualise each new contribution to the discussion, realised as a post to the list. The 4 fundamental styles or text-types of response outlined in Mod 2 are reproduced and glossed for convenience here:

In addition, there is one further style of text-type whose defining features overlap somewhat with those at the next Layer (2) 'down' (see section 1.5 below). This text-type is not formatted as a response to any previous contribution (although in theory all posts are responses to previous contributions) and is classed as:

As the description suggests, this style most often realises what at Layer 2 is termed an Initiation.
What I have called frames of coherence (or 'relevance') for example, are, of course, intrinsically related to the topics chosen by contributors for argument or discussion. In a coherent, or easily readable text, writers will most often put the main point or ‘topic sentence’ in initial position, especially in paragraphs (see for example Eden & Mitchell 1986). Martin (1992:437) calls such topic sentences ‘macro-themes’. Similarly every sentence will have a Theme , and the sequencing of Themes, or ‘Method of Development’ in a text is one of the means by which a coherent text may be built up. Whether themes are unmarked (i.e. realise grammatical Subject and thus are cast as responsible for the argument of the clause), and what actual semantic relationship obtains between these tokens in the texts, highlights an important facet of the interrelationship between the interpersonal, the textual and the experiential metafunctions in the topics which are taken up by other interactants (see also Thompson 1998, and Hunston 1989). For example, Themes are generally presented as given knowledge, and will have some relevance to the construction of tenor, or relationship of writer to audience by its assumptions as to what needs explaining or what can be taken as read.
In terms of the experiential metafunction for example, the nominal group, as outlined in Mod 1[note 3], carries a lot of semantic weight as well as responsibility for instantiating frames of coherence via identity chains as cohesive devices (see e.g. Martin 1992: 417ff, Cloran 1999, Hasan 1999). In the next section, therefore, a short discussion of the role of nominal groups is presented.

1.4.2.1 The double function of nominal groups in identity chaining and positioning

Nominal groups typically function as Participants in the clause, as well as acting to make claims or assumptions via their use in qualifiers and circumstances. In very dense texts, nominal groups may realise grammatical metaphors by which means verbal processes become unavailable for argument. Such nominal groups instantiate the Thing as Head noun, and thus may realise the Agent or Goal of a Material Process clause, but the same nominal group may also include textual information in the cohesive links they realise via both reference and deixis. Interpersonal information is also carried by the nominal group when naming and referring to other interactants by role ascription, for example, or via evaluative lexis in either classifiers or epithets. While some of these issues were raised in Mod 1, the potential strategic use of nominalisations needs to be addressed again briefly here, since it is implicated in the rhetorical development of arguments in context, and especially in the reading of invoked attitudes regarding ambiguous or underspecified targets of attitude, something which I rely on as a given in Chapters 4 and 5 below. The following extracted sentence will serve to illustrate some of these points:

Ex. 1.1

In my short time on the Net, almost a year now, the most common impulse for members of a group is[ to curb, to reign in, to conform the behavior of the newb to an habituated standard]. [wvn10.2/sally19]

In this clause complex, the topical theme the most common impulse for members of a group is signalled by 'presuming reference' (c.f. Martin 1992: 100ff), through the use of the definite article, and impulse is given the status of Head. The members of a group, occupying a less prominent position in the clause as qualifier of the Head noun, are not argued as experiencing such 'impulses'; this is presumed as given. To deny the assertion in the sentence would entail keeping the topical theme intact and arguing against the attributive process: it isn't to curb… Such a topical theme would also then be available to be referred to by means of a pronominal in the rest of the text. In contrast, the 'presenting referent' (as distinct from 'presuming'), an habituated standard, appears in the rheme, and therefore in the New position. However, its location as part of an embedded clause, also makes its actual relevance unavailable for argument. The existence of an habituated standard is presented as if its identity is retrievable intertextually via this grammatical placement. The marked circumstantial theme functions here to draw attention to the writer's claim to having valid experience in the matter by foregrounding her time of observation. Furthermore, by referring to the newb as a generic category of listmember, and via the definite article, such participants are ascribed a role with certain attributes which are presumed as understood by readers. It is interesting to note here the function of the graders most and common. If the nominal group is 'unpacked', these epithets can be observed to expand the dialogic space, and thus function under Engagement (Mod 2: II: 2.3) to help soften slightly the provoked negative judgement of the presumed members of a group. The clause complex needs to be unpacked as:

This rendering indicates that the impulses themselves are represented as separate from those who experience them, and that there exist other impulses - that in fact, the Actor, or rather the Carrier in the attributive clause, is one of many other impulses. The purpose of the statement is to classify impulses only, not the actions of members of a group. On the other hand, if the nominal Head impulse were also to be 'unpacked' and taken back to a form in which the transitivity of 'Agents' and 'Affected' were made clear:

then the functionality of the definite article in singling out only one of many impulses is lost, and commonly will imply that this is the main activity which members of a group carry out. 

My point here is that the grammar of this particular clause complex is 'motivated' (not necessarily consciously) as a strategy for expressing a negative judgement of generic participants as target - including in this case implied audience members - in a less than direct form. Having the judgement rendered in this form can function at particular junctures of an argument to present unargued, or presumed propositions, on which the writer may base further arguments. 

In the texts examined in this study, strategies involving invoked (or implied) judgements of ambiguous targets most often operate on both interactive and autonomous planes at once, and most often occur as summaries of sections of text for strategic reasons such as leaving interpretation more 'open'. Invoked attitudes have therefore been taken to signal boundary conditions of text segments as argued in Mod 2: II: 1.4. Two extracts below serve to illustrate this point. Both examples represent the final sentence(s) of a post, and in both the invoked attitude depends not only on retrospective (intra-textual) reference, but inter- and extra-textual knowledge as well. At the same time, as is common in these texts, the final or pre-closing move incorporates a change in orientation to the future, and in Ex 1.2 (and for this writer in general ), outside the discourse itself to the writer's material situational setting.

Ex 1.2

What is good for the goose ought to be good for the gander, and thus postmodernism is as critically a constituted fiction of social structure as the loading dock ethos to which I must report in a few minutes.[tvs47-/simon14]

Ex 1.3

Is there really such a need to determine "who's better?" Some of my best friends are ... oh, never mind. Shannah, are you drawing these lines because I've _agreed_ with you a couple times lately? [sft22.8/stan3]

Such types of closing move could be seen as involving what Sinclair (1987, cited in Hunston 1989:99) calls a change in posture which is signalled by changes in attribution and tense. These examples certainly involve the appearance of the writer and (relative to registerial context) a change to present or future time. In the case of Ex 1.3, the final interrogative sentence could be classed as encapsulating as well as prospecting - something that Sinclair (1993:12) claims is not generally a function of questions. In the examples above the appearance of the writer as Addresser, and the indicators of orientation to future time are underlined. Ex 1.2 also provides another example of presuming reference realised by a complex nominal group (highlighted in green) qualified by an embedded clause. At this point, what these examples serve to illustrate is the interrelationship of lexicogrammatical resources being deployed at certain points in the text where rhetorical "posture" (what Goffman opcit refers to as ‘footing’) shifts. In turn, such changes serve as one important indication of the articulation of text organisation identified in this study.

1.4.3 The relationship of Material Situational Setting to text organisation

The problem of incorporating a dynamic analytic perspective to texts of this type, i.e. what are essentially monologic in creation, and yet allow for dialogic-type responses within the same context of interaction, can be illustrated by discussions and analyses which attempt to capture and account for the patterns of unfolding discourse. Cloran (1999, following Hasan 1985) for example, argues that a 'rhetorical unit' (RU) can be classified according to its location on a continuum involving mode. The continuum has, at one extreme, language as ancillary to the social activity taking place, and as constitutive of the activity at the other extreme (c.f. above 1.2.1). It has already been pointed out (Mod 2: I: section 1, and above 1.2.2) that the use of language in email list interaction is entirely constitutive of its context of situation. Yet, to ignore its material situational setting (MSS: Hasan 1996: 39), i.e. its technological mediation, would render any explanation of its context of situation completely inadequate. This relates to the research problems encountered in this study, in which the tension that obtains between the two perspectives of text analysis, synoptic versus dynamic, is largely tied to a notion that the texts produced in any social activity can be classed on a continuum between written or spoken mediums. The analytic problems that this raises can be illustrated by reference to Cloran's (op cit: 199) discussion of RU's which can be classed by reference to their location at the ancillary end of the mode continuum. She observes that the 'rhetorical configuration' of RU's produced at this end of the continuum may be recognised by:
[the fact that](a) the central entities are the interactants themselves, and (b) the events referred to are occurring concurrently with the moment of speaking or will occur immediately as a consequence of the message.
Comparing what Cloran says above with the common features of texts produced in email interaction - a written, reflective mode using language as constitutive of the social process - central entities are similarly found to refer to interactants themselves, usually as I, you, we, or in actual forms of direct address (c.f. above Ex 1.3). Additionally, the events referred to in electronically-mediated texts can be viewed as "occurring immediately as a consequence of the message" if the "moment of speaking" is instead viewed as the utterance, i.e. the moment of reading, rather than the moment of writing, since response is considered to take place when the text is read by a conscious human participant . Furthermore, the use of deictics such as here, usually taken to indicate a concrete situational context involving close material - at least visual or temporal -proximity, is also quite high in these texts. In Table 1.1 below for example, the frequency of lexical items you, I, we and here in the thread "JVS" (n = 16,969), and "ALL" texts (n = 53,377) is compared with those in the cobuild corpus, and standardised to 1,000 words. Except for the British spoken corpus (brspok), you has a higher frequency in the representative text sample JVS than for any of the other corpora, and this is repeated for the items I and here. These features tend to demonstrate that, as might be expected, the lexico-grammar of the textual metafunction alone cannot be relied upon exclusively in this context of situation to match up with previous correlations linking it to mode, and for me, points to a context that entails a higher degree of relative interactivity (c.f. Mod 2: I )

[[Table 1.1: Comparison of some deictic markers in selected corpora
3 highest frequencies in compared corpora for each lexical item: 1; 2; 3]]

Hasan (1996: 46) notes that the differentiation between monologic and dialogic modes will be the most salient feature determining whether the negotiation of context - its norms or conventions appropriate for social activity in any community - is possible or likely, via what she terms ‘process-sharing’ (see discussion Mod 2: I). Her use of the term ‘dialogic’ in this sense refers to interactants having immediate feedback possible in their context of situation. As discussed in Mod 2: I, the context of situation engendered by an email list, as an asynchronic mode of interaction, does not make such immediate feedback possible, but it does allow delayed feedback and it is this type of interactivity which was concurrently investigated in this study. A continuum extending between most institutionalised and most individuated extends the subcategorization of context in Hasan's (op cit) model, and accounts for the ways in which convergent and redundant coding, especially in material situational settings (MSS), acts to reduce ambiguity, or as Hasan notes, reduces the probability of individual negotiation over what is 'norm-al'. By ‘convergent coding’ Hasan refers to the means by which interactants use the available resources both linguistic and material, to increase the likelihood that their meanings will be understood and acted upon. When interaction is face-to-face, the possibilities for redundant or convergent coding are increased, with the consequence that the oft-remarked-upon lack of visual and auditory cues in email interaction tends to result in a context which is ripe for misunderstandings. In order to reduce this possibility, interactants may resort to several mode-related avenues for dis-ambiguating their verbal behaviour, as discussed in detail in Mod 2: I. The nature of the institutionalisation of such methods of rendering the relevance of the verbal behaviour more (or less) transparent is related to the 'layers' (tracks, or channels) of meaning-making introduced here, which interactants employ dependent on what is available in specific MSSs. It is these devices - of formatting, cohesive harmony, and evaluation - that comprise what I refer to as frames of coherence, similar to what Hasan (op cit: 46) refers to as frames of relevance, and which act to co-articulate the boundary conditions of text-events, and thus realise, or instantiate at least, what I am calling the rhetorical organisation potential (ROP) of these texts. Because I see such ROP as negotiated and developed over time, as open to change, and as a type of generalised abstraction taken from a sample of representative texts in this study, I prefer to see the actual posts as ‘instantiations’ of the ROP rather than ‘realisations’ of something which is already ‘there’ in the email list to begin with.

1.5 Layers of Framing

1.5.1

The following section presents a summary of what constitutes the layers of analysis I introduced above, together with a description of certain textual features which are salient at each layer, after which, in section 1.6, this approach is illustrated by reference to a text (post) which the resulting model is able to accommodate despite the post's unconventional framing - or what is better termed its atypicality in terms of its appearance in this context of interaction.
In effect then, layer describes the levels of analysis that are attended to in order to characterise the organisation of text-events in this activity mode. It is these recurrent text-events that I have generalised as a model I call 'rhetorical organisation potential'. In chapter 2, I go on to describe the nature of the rhetorical organisation potential of these texts in detail, together with a description of the method used to derive the model from an analysis of representative texts.

1.5.2 Layer 1: Formatting as top level framing

At the first, or 'outer' layer of analysis, relevant features include the obvious interface and writer-determined formatting features outlined in Mod 2: I: section 3.3. The labels for the four fundamental styles or text-types prevalent in most lists are reproduced above (1.4.2) , and these make reference to the gross means by which posters construct their whole texts as contributions to an ongoing conversation via the use of graphic means such as signalling the quotation of parts of previous posts. In this sense, Layer 1 analysis treats whole posts as complete objects after the fact. This level of analysis is synoptic to the degree that it attends almost completely to the expression plane, and how the disposition of quoting, spacing, and other punctuation within the body of the post - as well as the technological interface itself - helps to frame the actual content of the text in order to cue meanings. It is concerned to discover how the writer has set apart his or her turn(s) within the post itself.

At this level also, the subject line, and the contents of the header in general, form one of the first framing devices that the reader has available. The subject line in particular frames the content of the post as part of an ongoing series of contributions - in the first instance by the technological insertion of "Re:" when the post is made in response to another on the list, as well as when the writer chooses particular words deemed relevant to the content. Other information in the header can also be considered to frame the content in this sense, since it tells the recipient who the writer was and at what time (and place) the message was sent . However, in determining whether a post is a Response of whatever type, Layer 2 features are more salient, although formatting signals their presence. In this sense, the subject line at Layer 1 is an empty value: it is part of the outer layer and remarkable if absent, but the actual content only becomes relevant when other features at Layer 2 are not present (c.f. next section). Features relevant for analysis at this layer are obviously related to many of those outlined under Dimension II of the cline of relative interactivity introduced in Mod 2: I: 3.6.
[Eden & Mitchell paragraphing for the reader?]

1.5.3 Layer 2: Responses and Replies: reference and exchange structure

This layer is concerned with the relationship of the post to previous posts (or parts thereof), and with the signals used to indicate an orientation to the context of the ongoing interaction. This level of analysis has a dynamic orientation to the degree that it is concerned to describe the means by which writers indicate and readers might perceive how the post can be re-contextualised. Rather than treating the whole post as a bounded object, this level of analysis looks at intertextuality in both the content and the expression planes. As mentioned earlier (1.1.2 and 1.3.3), the use of quoted material from previous posts can be viewed at one level as part of the manifest intertextuality of the text. The means by which this material is set apart from, or integrated with the turns constructed by the writer can be indicated by both formatting and by discursive features within the text, as will be illustrated below and in more detail in Chapters 2 and 5. Writers may make reference to previous contributions in a variety of ways to indicate the relevance of their own contribution, but beyond this, they may also indicate their stance in relation to the proposals and propositions made in previous contributions as well. This issue was also introduced and discussed briefly in Mod 2: II: 5.
Briefly, from a dialogic perspective and the writer/Addresser's point of view, all their contributions are responses to some previous text, and in the context of an email list, my observation is that most contributions indicate some relevance, and hence their responsiveness, to some topic addressed previously on the list. Viewed from the perspective of the reader/Addressee, all contributions engender some response on their part , and this is the default. However, these responses are not always made 'overtly', i.e. in writing, and so, within the category of 'overt response', the first entry condition for purposes of analysis is 'written & posted response'. In order to determine whether such overt responses are directly responding to some previous contribution (as distinct from responses to general ideas and topics familiar to listmembers), elements appearing in the subject line and in the body of the post are taken into account. When these elements do not appear, then the post is classified, at the next entry point, as an 'initiation'. At the same time, however, due to individual posting styles, or the interface used by some listmembers, etc, these so-called 'direct responses' may also be made with new subject lines, and in these cases, relevance is usually indicated only within the body of the post. For the purposes of this study, and the description of the typical or conventional post, this method of response is classed as 'marked'.
Lexicogrammatical features which are relevant for this layer of analysis are those of IDENTITY, such as repetition, replacement, re-statement and reference (i.e. phoricity: cohesive collocation, lexical co-reference, synonymy; (non-manifest) intertextuality: assumed knowledge, etc), NEGOTIATION, and the nature of exchanges (c.f. Martin 1992: Chs 2 & 3), and TAXIS, i.e. expansion (elaborate, extend, enhance: c.f. Halliday 1987; Martin 1995). In terms of NEGOTIATION, what is attended to at this level are features which relate to the argument of the clause, and whether the negative or positive evaluation of previous statements is taken up in the response. In other words, whether the overt responses made in posts are congruent in terms of MOOD . The default position in this case is not 'support' (negative or positive) but 'non-support', which includes the response "ignore/silence" as mentioned above (where 'ignore' relates to direct elicitations, and 'silence' to statements of fact of opinion. See Ch 2:#). In order for a response to be classed as a reply in the Goffmanian sense outlined in Module 2: II: section ## the text needs to represent some from of reciprocal and congruent response. Between these two classes of Response are a variety of responses which address the propositional content of the previous quoted contribution, but provide a challenge by supplying meta-commentary, by dismissing the value, status, or relevance (Hunston 1989) of the content, or diverting the topic in other ways. As an example, in the excerpt below, the response takes up (via [support: confront]) the position by arguing with it, and thereby makes a reply despite the disagreement:

In contrast, in the following excerpt, the turn which follows the quoted material does not address its positioning, and would therefore be classed as a response but not a reply:

One interpretation (pattern of understanding) of any "anger" felt
"about" some event that does not occur in one's immediate physical
presence is that it is (made possible by) previously felt but not
resolved rage, usually left over from infancy. [gen02.18/ter]

In the response given in the example above, the arguability of the main clause has been changed, with the Subject of this second clause being nominalised as 'anger', while the Subject of the first framing clause quoted has become an (unstated source's) interpretation of 'cause of anger' in general. This means that the writer of the response has adopted a "Speaker" role (as distinct from an Addresser who is responding to the Addressee) in which he is the 'animator' but does not acknowledge his status as 'principal' in Goffman's terms, instead extravocalising, or sourcing the attribution to another authority: one interpretation (c.f. Mod 2: I, section 3.6.1). The writer here gives information about 'anger' as a disembodied emotion rather than as a process, a process felt by a conscious 'emoter'. He does not respond 'in kind'. To put it in terms of Berry's (1981) framework, an offer of information in a K1 position (an "A event"), has been responded to by yet another K1 move: instead of accepting the information given (and extending, elaborating or enhancing on the propositional content), it has been treated as a request for information - as a K2 move, or "B event". A more congruent realisation of the exchange would allow a change of Subject, but with the process maintained or negated via polarity. For example: "Yes, many people are angry about…" or "There's no need [for you] to be angry about…", or even "I understand your anger, but…". These would at least maintain a number of co-referents in an identity chain apart from the semantic domain which includes angry and anger. From the perspective of the transitivity, [to be] angry is in the first instance the Attribute of a conscious Carrier, whereas in the response, anger has taken the Carrier role and been given attributes of its own.
The system of Response types is outlined in detail/represented visually in Chapter 6
The content of the subject line in the Header is again implicated in analysis at this layer and acts as a signal of relevance, indicating whether the contribution will address the content of another contribution, or initiate a new topic.
The contribution of "non-manifest" intertextuality - of references to assumed knowledge, metaphor, shared allusions and so on - is also relevant to this layer of analysis. Expectations that participants will be able to retrieve such references is dependent on what Halliday and Matthiessen (1999) amongst others have termed phylogenesis: the development of a semiotic system(s) within a community. Because the list conversation, if regarded as ‘whole text’ has involved large changes in speaking subject (Bakhtin op cit), and even changes over time in the mix of interactants, the term logogenesis cited earlier would not be applicable here. The relevance of the development of conventions for positioning others through evaluation especially was introduced briefly in section 1.3.1 above, as it is particularly salient for the discourse organisation of the group in the study. This is revealed by the extensive use participants make of a wide spectrum of strategies for invoking attitude (in contrast to, but not to the exclusion of inscribing attitude: see Mod 2: II. #), and not only limited to invocations which rely on intertextual allusions. Because such positioning strategies can help account for the construction of poster identity within the group, this aspect of the system of Appraisal will be discussed in more detail in Chapter 4 below, with reference to the analysis of attitude in the texts. The analysis of attitude and the disposition of attitudinal prosodies is, at the same time, used as the fundamental signal of rhetorical text organisation in this thesis, and is a focus of Layer 3 description outlined in the next section. Layer 2 analysis is discussed again in the latter part of Chapter 5 where the possibility that poster-gender influences response patterns is presented.

1.5.4 Layer 3: Rhetorical Text Organisation: indicators of staging and the development of argument.

This layer again treats the post as finished object, but is concerned to also identify intra-text signals of coherence and the development of an argument via logogenesis (c.f. Halliday and Matthiessen 1999, Martin and Rose 2003). In this sense, the features which signal the framing at this level are treated both synoptically and 'dynamically' to the extent that it views rhetorical positioning as unfolding with the co-text. From another perspective, this means that analysis at this level is also concerned to identify text development by paying attention to work being done on the interactive and autonomous planes of discourse, and takes into account what Sinclair (1993) glosses as deictic and logical acts. In Mod 2: II I also argued that one of the main ways that the development of the argument may be identified, is through an appraisal analysis which takes into account not only the dispersion of attitudes themselves, but also the sources and targets of evaluation as they appear in sequence throughout a text. These, in combination with strategies which appraisal classes under engagement (see Mod 2: II: 2.3), trace the evaluative positioning strategies of the writer, and the writer's construction of the ideal reader whether a named Addressee or the audience of 'onlookers'. As outlined in Mod 2: II, section 2.3.2, anyone, from named Addressee through to unknown 'eavesdropper' may be the real readers who may take up or resist the positioning in overt responses, and future research on the actual relationship between positioning and nature of responses is planned using the framework introduced in this thesis, as proposed in Module 2: II: section 6. In the context of this thesis, however, it is the means by which positioning strategies articulate the relationship between writer and projected audience members (stance of the writer), and the negotiation of 'identity' (deemed the social purpose of the texts in this study) - which in turn depend on the generic conventions available in the local ROP - which is the focus of this layer of framing. 

My argument, similar to those proposed by Hunston 1989 and Hood 2004, is that evaluative peaks, or prosodies, are one of the main means by which an argument is developed and by which it can be analysed. Evaluative prosodies are obviously related to the positioning evident in any text, but my own position is that these prosodies are also theoretically and practically inseparable from those aspects of the text's coherence which have traditionally (under SFL approaches) been treated as realised by textual, logical, and experiential metafunctions in the lexicogrammar. These aspects of a text's coherence I view as essential scaffolding for the development of the coherence in any text and for the analysis of its generic structure potential, but there have been few studies to date which focus on the interpersonal aspects of a text and its tenor in order to arrive at descriptions of genre organisation potential via rhetorical text units. Thompson (1999) discusses in detail the implications for construal of context of situation in SFL terms, and makes similar observations on the lack of absolute hook-up between the lexico-grammar of the metafunctions and the realisation of aspects of the context of situation, Field, Tenor and Mode. He notes (opcit:106) that Halliday has "consistently stressed that correlations between contextual parameters and metafunctions are a matter of tendency and statistical probability, not of determination". In addition, the focus on what I am calling "markers" in helping to construe attitudinal positioning and argumentation parallels Thompson and Zhou's (2000) investigation of conjuncts with attitude (p.124), and their "emphasis on seeing texture and structure as created by interactive negotiation between writer and reader, rather than simply as the reflection of objective logical relations between propositions" (p.140), and these features of the texts are attended to at Layer 3..

1.5.4.1 Specific linguistic indicators

What is attended to at Layer 3 may consist of any discourse elements which are viewed as useful in tracing the means by which a text’s coherence, specifically its argumentative purpose, is constructed. Layer 1 provides the formatted scaffolding that a writer uses as indicators of the main sections of their post, while Layer 2 attends to indicators writers use to signal a post’s context as part of an ongoing ‘conversation’. At Layer 3, the organisation of the argument within the main stages of the post were examined to discover what linguistic strategies are typically employed to organise this argument. At the level of the paragraph, initial or orienting clauses and clause complexes were examined to discover what means writers use to orient readers, and similarly, what writers choose to conclude their paragraphs. Longer stretches of prose, termed ‘stages’ in this model, were also treated in this way, and the model outlined in Chapter 2 describes, for example, Opening and Closing Framers whose internal strategies realise their organisation.
In this study, a variety of linguistic systems were noted ‘on the fly’ using a dtd as analytic approach, as will be described in more detail in the next Chapter. However, while such systems as lexical cohesion (repetition and substitution), collocation, and Thematic progression were observed in passing, the main features attended to in this study are focussed on a very large group of discourse markers, since they were observed to have been used by writers in signalling the development of the argument and the articulation of strategies which form arguments within stages. By ‘strategies’, I refer to discourse patterns subsumed under the twin categories of matching and logical relations such as assessment-basis, purpose-means, problem-response, and hypothetical-real, for which markers such as conjunctions, adjuncts, and disjuncts are essential.
It is at this Layer also that the dispersion of attitude, especially that of invoked attitudes, was determined as significant in signalling argument organisation. It needs to be noted that attitude was analysed using a separate dtd, and that both analyses were compared in order to observe interference patterns created from an overlay of both.

1.5.4.2 Invocations of attitude

Specific features of the discourse which are implicated for the framing at this level can be exemplified by meta-discursive devices, such as intra- and extra-vocalisation, and other features of engagement implicated for construing provoked appraisal, as well as intertextual reference, or evoked appraisal, which was outlined in detail in Mod 2: II: section 3.3.3 (inter alia). My argument in Module 2 was that rhetorical strategies of provoked and evoked appraisal are a primary means of constructing overall arguments, particularly at certain junctures where an Addresser, mindful of his/her audience, implies (provokes or evokes) judgements regarding the values, positions or (potential) behaviour of audience members in order to maintain affiliation, or to ward off disalignment. By invoking attitude through the use of ambiguity of target, source, or evaluative lexis, the writer can make judgements without specifically putting alignment with audience members as risk, but at the same time, these instances of ambiguity appear to be located at regular intervals in the texts, and serve to both articulate the progress of the argument and highlight the writer's assumptions regarding audience and their possible ideological/axiological differences at the same time. Specifically, the proposal set out in Mod 2: II, was that instances of provoked and evoked appraisal in these texts provide one of the most useful ways of approaching the identification of textual boundaries or phase shifts. It was contended there that such instances of invoked attitude tended to be employed at the close of phases of argument, especially in the pre-closing sections of posts themselves. These findings will be demonstrated in more detail in Chapters 2 & 3, 4.

The idea that writers use both opening and closing sections of texts for highlighting significant meanings in their texts, and that readers expect this disposition of meanings is not new. Eden & Mitchell (1986: 418) for example note that: “Readers expect to find at each paragraphs’ peripheral points something which merits special attention”. One of the main approaches in this thesis is to make observations of features at Layer 3, overlaid with those at Layer 1, and thus describe the common or conventional ways that signals of framing are co-articulated: to discover what typically constitutes the peripheral points of texts and parts thereof.
Figure 1.2 below sets out the main types of invoked attitudes identified at the time of writing, including examples of how these types of provoked and evoked attitude may be typically realised. In Martin and White's then classificatory system (c.f. below), subcategories of invoked attitude are all subsumed under evocation, but my own analysis suggests that strategies covered by 'flagged' and 'provoked' attitude are better seen as having a closer relationship to each other. This is because, for example, grammatical metaphor and instances of nominalisation as discussed above (1.4.2.1) are certainly deployed as resources in the evocation of attitude, but are located in Martin & White’s schema, on the furthest end of the cline of more experiential, less 'saturated' evaluative meanings which are highly dependent on other co-textual signals. In contrast, my approach is to view the provocation of socially shared attitude as encoded in highly evaluative lexical metaphors located at the other end of such a cline. In the middle are strategies which involve such "markers" or flags of attitude as have been discussed variously under headings such as engagement, conjuncts with attitude, and matching relations.Figure 1.2: Typology of invoked attitudeThe typology represented above shows for example, that flagged attitudes refer to such resources of co-textual signalling as those subsumed under Engagement. In Chapter 3, one of the means for signalling presumed dis/alignment with interlocutors is reported in more detail: the use of 'not', 'no' and other signals of negation which not only organise the argument on the autonomous plane, but also act to position readers in a variety of ways which set up or provoke the reading of evaluative attitude in texts. This type of 'flagging' of attitudinal positioning is also addressed in Chapter 3.




Figure 1.2: Invocations of Attitude 

In terms of the category [evoke: afford] 'identity chaining' (see for example Cloran 1999, Hasan 1999, Martin 1992) provides a further means for tracing evaluation together with its targets and sources, and the coherence of the texts, but identity chaining is in any case, concurrently investigated in any detailed appraisal analysis. As investigated in Module 1, the analysis of texts concentrating on the nominal group, transitivity, and the realisation of social actors can also contribute to the tracing of such 'afforded' attitude, especially when their reading is dependent on signals that are outside the scope of the primary text.
This view of staging or organisation can be likened to the move structure framework used by Dudley-Evans, Swales, etc, for the analysis of academic discourse. Lewin et al (2001) refer to these types of moves as 'functions' (op cit: 17) and they cite a study by Dubois (1997) in which moves are classified as 'rhetorical functions'.

1.6 Layers exemplified

1.6.1 Overview

The following section provides an example of one of the more un-conventional texts as a means of demonstrating what the model attends to when identifying boundary signals which are then described using a dtd as template. Chapter Two goes on to describe the conventional staging of posts in terms of this dtd and closes with a number of example posts which are typical of the macro-genre and the 4 fundamental text-types developed within this speech community (see above 1.3). Although the data on which I base my findings consist of files of almost every post contributed to the discussion list dating from October 1995 up until the present day, texts which were used for the close analysis which informs this study and the resultant model were chosen as representative of the interaction and as prototypical texts. My model is therefore necessarily based on a selection of the products of the list's activities, and it attempts to account for the dynamic creation of meaning in the context of unfolding of the discourse and within the text-units identified. The selection of what counts as 'representative', and the accounting for aspects of the meaning-making in text events is also based on my own active participation in the group. The significance of active participation in this type of case study was argued in Mod 2: I: section 4.1, where my own assumptions on the nature of group membership and culture were acknowledged as motivating the methodology adopted. This methodology will be outlined in detail in chapter 2, in which the working assumptions, the text selection, and the framework itself will be presented and illustrated.

1.6.1 "There goes rhymin Simon": Re-contextualising the text [tvs234.56/stan]

What follows is one text taken from the concluding stages of the thread JVS ('jerry versus steve': Chapter 2 below outlines a description of text tagging systems). The post appears to be organised somewhat unconventionally from the point of view of the macro-generic stages typical of the list interaction, in that it is almost completely comprised of a culturally recognisable core-genre [limerick]. However, in the context of the ongoing interaction, and despite the lack of obvious co-textual framing at what I am calling Layer 1, the positioning of both Addresser and especially the evaluative target Addressee, would be immediately understandable for any participant in that conversation, the putative Addressees. In this sense, its status as a coherent contribution to that thread can be accounted for using the resources of reference and evaluative positioning at Layers 2 and 3, and the most obvious of the resources used are outlined below. In addition, some of the resources by which identity construction is effected via such intertextual reference and evaluative positioning are again discussed with reference to this text in Chapter 4. As an example of the 'prototypical' text, [jvs234.56/steve33] reproduced here as Ex 1.6, needs to be classed as an extreme example of the macro-genre, while at the same time, it constitutes a relatively simple example due to its conventional core-generic staging. It therefore provides a good introduction and test case for the presentation of the model in detail in Chapter 2. Meanwhile, the sections which follow demonstrate how the layers of framing act to provide the levels of abstraction on which the model is based.

And your humor is soaking in bile

6.The couching of feelings in theory
Makes some of us itchy and leery
Straightforward gripe
Trumps prettified snipe
And leads to clear vision, not bleary

7.My message I'll sum up discreetly
In verses so softly and sweetly:
Hiding one's rage
On CRT page
Says the very same thing, but effetely.

1.6.2 Text Layer 1: Top level framing

Ex 1.6 above can easily be seen as divided into 3 main stages as indicated by its overt formatting, which in turn is partly a feature of the interface, partly a feature of the signalling of a culturally-recognised core genre, limerick, in which attitude can be 'provoked' rather than inscribed, via expectation of amusing rhyming 'twist' in the final lines of each stanza.

1.6.2.1 Header and Body formatting

At its outermost 'layer' an email post can be divided into two main stages as provided by the interface, or technological mode: the header and the body, as already discussed in section 1.5.2 above. This may be easily observed in the example text above.
The body of this text is formatted as 2 stages (more specifically 3 stages if the typical closing framer stage is taken into account - in this case consisting solely of the handle); the first or main turn, and a preclosing stage or short turn which is marked as separate from the rest of the text by means of white space ('carriage return') as well as a short line of asterisks. The main turn of the body is divided into stanzas conventional for this core-genre (or ‘activity sequence’ Martin 1992: #; Lemke 1995a: 86), and signalled explicitly by the separation of each stanza (termed part for the generalised labels used in the framework outlined in more detail Chapter 2 below) by a line of white space. Finally, the end of the post is comprised of a closing framer, again signalled by separation via the use of white space, and in this case comprising the first name (or handle ) of the writer. At this Layer, the post is marked in terms of the local list-current conventions mainly through its lack of an opening framer. At the same time, this style of text can be classed as an example of the "non-indicated" style (c.f. 1.4.2 above) rather than an "initiation", because of its obvious relationship to the ongoing context of discussion, as evidenced in other Layers.

1.6.3 Layer 2: Response or Reply?

There are several indicators that this text can be re-contextualised as part of an interactive conversation - mainly reference to list-current identities, together with actual naming of other posters/contributors, as well as the evaluation of these named and referred-to contributors. The subject line used, There goes rhyming Simon . . ., indicates that the post has not been made in direct response to any other, due to its lack of the marker ‘Re:’ and this would usually indicate it has been made as an initiation. However, as noted above, reference to rhyming Simon in the subject line would alert participants that it was made in response to an earlier contribution by the poster identity Simon, who similarly posted a limerick previously ([tvs188.50/simon19b]). A typical Reply makes its initial evaluative positioning clear by maintaining the topic in some way, and this is not obviously the case with this post (c.f. Chapters 2 and 5 below, and Mod 2: II. section 6 for discussion of typical Response and Reply openings). At the same time, the text's main evaluative target, although not referred to by name, is easily retrieved by list participants due to the convergence of several thematic strands (Lemke 1995a: see discussion Chapter 4 below) and therefore this post can be classed as part of the ongoing thread, and as a Response to a specific previous contribution, rather than a Reply. The presence of so-called thematic strands, related to topic maintenance, is therefore definitive for distinguishing between a Response and an Initiation.

1.6.3.1 Reference

In determining this post’s status as part of an ongoing thread (despite its lack of maintained subject line in the Header), the first two stanzas - by means of intertextual reference - both orient the readers and claim their affiliation with the use of referents such as Simon, Kaylene, CritiC, a trickster, Ray, bozo-filled mix, 12-steppers, MBTIs, Aussies, and bikers. The actual topic of the post begins at stanza three with the presumed reference to tempers start flaring. The topic of ‘hidden anger’ on the part of one of the participants has been maintained throughout the thread. Chapter 4 discusses the implications of this for (invoked) evaluative positioning, but the point here is to note that at Layer 2 such referents in the text indicate its membership in a thread: a chain of responses to a similar topic.

1.6.3.2 Argument

Classification of a post as Response or Reply also depends on the evaluative stance taken by the respondent to the positioning in the responded-to post(s). As stated earlier, this is usually dependent on whether the Response realizes congruent mood to take up or argue with the earlier positioning, and/or provides evidence of topic expansion (enhancement, elaboration, extension). If it is agreed that the post being discussed here is a response to a limerick contributed earlier by the poster identity Simon, then it should also show specific reference to that post. In this case, there is no room for congruent argument within a typical exchange, and so because the genre [limerick] does not use the resources of NEGOTIATION, the post has been classed as a Response rather than a Reply. On the other hand, it does take up the positioning to some degree, as evidenced in the following excerpt from the earlier contribution:

Ex 1.7 Excerpt from [tvs188.50/simon19b]

There once was a psych, analytic,
A Freudian internet critic,
His cold common sense,
And a sly arrogance,
For some was far too acidic.
Our Stan who likes object relations,
And long Harley biker vacations,
Says to us, Netdynam,
"Yo group, here I am,
But I'm not here to fill expectations."

The acceptance of the positioning seems to be most evident in the writer ("Our Stan") taking up the positions made for him in the above excerpt: he responds by making acidic comments on the members of the group, Netdynam, expands on his [status: authority] as psych, analytic by using the terms inflation, projection and denial, and closes by reference to his identity as a biker.

1.6.4 Layer 3: Rhetorical Organisation Potential realised in the text

At this Layer, the "content" of the main stages of the text are observed, in order to derive stage intra-organisation labels in terms of their "expression". In the case of Ex 6.1 the main stage consists entirely of a limerick, and as such, the ‘paragraphing’ is constrained by the form. As well, the evaluative prosodies are somewhat constrained by this form also, as discussed further below. The ‘pre-closing’ stage employs intertextual reference to the core genre and relies for effect on the audience’s familiarity with the content and form of other limericks, as well as the situational context – the thread - in which this is a coherent contribution, and in which he is claiming ‘victory’ though his prowess at genre manipulation .

1.6.4.1 Use of core-genre

The use of a core-genre, limerick, as the entire content of the main stage of the post constrains the choices for argument organisation employed, since the constraints of stanzas and rhyming override other needs for markers and common prose signals. At the same time, it allows the writer to signal that the content must be read against the culturally assumed background of ‘play’, and the expectation that the last line of each stanza must provide some evaluative or semi-surprising quip. Within this main stage of limerick, several sub-stages or stanzas may be observed. Stanzas 1 and 2 provide the orientation, by outlining the ‘setting’: a description of the email group discussion. The ‘marker’ in this case could be said to rely on an intertextual signal of the genre ‘fairy tale’: There once was…
The actual topic of the post is introduced in stanza 3, as noted earlier, and this is where the report of Affect is first introduced: tempers start flaring; as an action with no specific Emoter (in Appraisal terms). The possible negative value attached to this Affect is ensured with the Circumstance which follows: feelings find overdue airing. As noted previously, the target of this negative evaluation of a situation is not stated, but readers familiar with the thread will have no trouble retrieving the intended target in the context of the writer’s previous claims regarding his behaviour. Stanzas 3 and 4 fall naturally together, while stanzas 5 and 6 extend the negative evaluation of the target. The final stanza (7) is a claim, framed as a pronouncement, which 'sums up' the negative evaluative stance of the writer towards the target. Each stanza, as expected, closes with a negative appraisal of the target or a comparative positive appraisal of actions which the unnamed target does not display.
In summary, the model divides the body of this post into two stages: turn and closing framer, the main stage being further sub-divided into 2 sub-stages: turn-parts and a pre-closing reframer. The turn-parts is comprised of an opening and a continuing, and the continuing section is also divided into parts - in this case, realised as stanzas.
Such stages are usually derived in the model by looking at a combination of signals of boundary conditions. The ones I have taken into account in this study are changes in orientation such as tense, attribution, addressivity (this chapter: contact eldon), change in topic, or changes in evaluative positioning. A loose group of textual and interpersonal markers were also tracked and treated as 'framing cues' of this type.

1.6.4.2 Evaluative prosodies in the text

This section focuses on an example of evaluative prosody, what could also be referred to as 'changes in evaluative positioning' over longer stretches of text. It is a term referring to accumulated values in a text, and so relies on signals of cohesion and reference to both mark the boundaries of such phases, and to signal that series of evaluative positions are linked within them. Many such linked positionings can be seen to provoke an overall attitude (c.f. Fig 1.2 above).
As observed in the previous section, Stanzas 3 and 4 are both directed towards a similar topic – that of feelings and emotions in general. The stanzas which follow are then linked to it by the rhetorical strategy of expansion . Stanza 4 begins with the Theme and Subject emotion, which is then appraised as curious. The following 2 stanzas, 5 and 6, are grouped as a subsection, since they expand on the topic of emotion in more specific terms yet also refer to general evaluations of ways in which ‘emotion’ may be approached. Specifically, in stanza 5, types of emotional reaction are evaluated by ascribing to them the means to turn discussion to trial, with the example of an unnamed possessor of humour which is negatively judged as soaking in bile. Stanza 6 changes theme while retaining semantic domain with the couching of feelings in theory. This nominalised activity has the power to cause negative [appreciation: reaction]: itchy, and negative [affect: dissatisfaction]: leery; in some of us. This in turn represents a strategy which claims affiliation with readers, and at the same time wards off the resistance of those who may enjoy ‘couching feelings in theory’ by means of dialogic expansion. Stanza 6 also contains the highest concentration of negative Appraisal of the unnamed target, via both positive and negative Appreciation functioning as tokens of [judgement: capacity: negative]. This stanza is the last but one - and in these texts, one of the common patterns observed is that the last but one unit is often the bearer of the evaluative nexus or peak. The pre-closing or final unit in this pattern is then given the function of 'coda', realized in general as an orientation to some future, usually by any or all of textual, ideational or interpersonal prospection (explain Ch 2?),
In this text, this function is not borne entirely by the final stanza of the limerick which begins with my message as theme, and claims to sum up what has gone before: the final stanza here has the function of "sum-valuating" the larger unit, and this is then followed by the pre-closing unit, which characteristically changes orientation, here represented by

Ex 1.7:

8. Biker T-shirt: "I AM the man from Nantucket."

The final attitudinal term in the final Stanza 7, effetely, brings together some of the other themes of jokey masculinity which have been evident in the thread up until this point, and once more evaluates the target with negative [judgement: capacity].
[Thus the post can be seen as having an organisation at Layer 1 represented by a limerick and as comprised of 3 main stages. The stage encompassed by the Turn may be further described as ‘organised’ via its semantic prosodies which refer to intertextually-shared identities as the targets of evaluation. These evaluative phases in the body of the text are signalled by both inscribed and invoked attitudes.]

1.7 Summary

This chapter has argued for the approach used in this thesis for analysing a set of representative texts in order to propose a typical or conventional macro-genre for the posts produced by members of a specific electronic mailing list. The approach was designed to look at a variety of discourse signals writers use in organising their posts and the arguments they contain. The approach was designed to investigate the organisation of posts by viewing each post as a text employing these signals, or framing devices, at 3 distinct levels of analysis. The levels of analysis were termed Layers, and these were described as being integrated within each post. Layer 1 attended to the ‘gross’ formatting features of the texts, such as the use of paragraphing and other formatting features available in the medium. Given the use of paragraphs and other formatted signals of stages within the posts, the approach is described as setting out to examine how arguments are organised within these overtly signalled stages. Specifically, the approach uses a methodology outlined in more detail in the next Chapter, in which orienting and concluding sections of stages are observed, and the strategies for organisation of argument using contextual markers is described. Layer 3 was introduced as attending to these discourse functions, and in addition, as encompassing the insights provided by attitude analysis which was presented in Module 2: II. The overall purpose of this study was to propose a model which I have termed the rhetorical organisation potential (ROP) of these types of texts and which is set out in Chapter 2 to follow.
Chapter 2 presents and explains the dtd through which the analysis was conducted and refined. In addition, the set of representative texts used for the study, and the methodological approach adopted is introduced and defended in further detail. The resultant typical macro-generic text organisation is discussed through examples of the 4 typical formatting styles first outlined in Mod 2: I.
