Theoretical Background

Discourse as a text in a real communicative situation can be interpreted in different ways. It can be regarded as a «mental model» (Johnson-Laird, 2001), representing a generalized summary of our knowledge and understanding of the world; as a «frame model» (Minsky, 1969; Fillmore, C. J. 1976, 1982), arranging perception about various ways of behavior in typical situations; as a «script model» (Shank, 1975; Schank, Abelson 1977), presuming development, shifts and adjustments of those typical situations. To study the communicative aspects of discourse, we use a «situational model» elaborated and offered by Teun Van Dijk (2008, 2009), which combines the principles of social categories analysis to define our understanding and behavior within a social context with personal subjective knowledge (evaluation, opinions, patterns), as well as a social-semiotic approach of Michael Hall-iday (2003) and his discourse model, interlocking empirical, logical, interpersonal and contextual levels of analysis.

In this work we have applied a sociolinguistic approach towards an understanding of discourse. This implies that discourse is communication between people belonging to a particular social group. According to Vladimir Karasik (2002), this status-oriented discourse can have an institutional character. There are many different kinds of institutional discourse in our community, such as scientific, mass media, political, religious, pedagogical, medical, military, etc.

Valeria Chernyavskaya (2006) highlights the social context of discourse in arguing that modern discourse analysis is focused on the character and level of influence of various extra-linguistic factors on the language of the discourse. Discourse analysis has to answer the question of how the author, the receiver of the message, the field of communication, the channel, the intention of the speaker and so determine discourse organization and its language.

Definition of Academic Discourse

By spoken academic discourse in this work we mean a kind of scientific and institutional discourse whose purpose is to inform students. For our research we have chosen the lecture as one of the basic monologic genres of scientific discourse: academic discourse is a homogeneous lecture devoted to one topic. The peculiarity of the studied academic discourse is that it has a special addressee that consists of students who study English as a foreign language, with the attendant difficulties caused by listening to a foreign language, which means listening to and understanding a foreign speech, implying a number of psychological challeng-

es. One of them is the irreversibility of the process of perception of speech, which requires a great deal of attention from the listeners.

In addition, the lecturer needs to be able to navigate the communicative situation, feel the addressee, and anticipate their reaction in preparing lectures and directing educational interaction. This is particularly important, as the recipients are students who are learning English as a foreign language. Since it is not their native language the lecturer has to take into consideration the linguistic and cultural competence of the listeners, their ability to understand him/her. That is why the contact with the students and the need to create a free and easy atmosphere in the classroom are very important for the linguistic, communicative and pragmatic organization of the discourse.

Discourse must have a coherent text and explicit textual references. A substantial number of studies (Grosz , Sidner (1986); Mann, Thompson, (1988); Martin (1992); Foltz, Kintsch, Landauer (1998); Mar-cu (2000); Budayev (2009)) examine the principles of inner organization of the discourse and text. By discourse elements many linguists mean those elements that play a very important role in the organization and structure of the discourse. Anna Prokhorova (2007) points out that besides their cohesive functions they may also have some pragmatic aspects. Most discourse elements can express the opinion of the speaker, the relationship between the speaker and the listener, logical links between the ideas. They also can be studied from the point of view of pragmatics. The intention of the speaker can influence the language of the lecture and the way in which the ideas are connected with words.

English academic discourse has a wide range of discourse signals optimizing the process of its perception and aimed at the recipient. It should be noted that oral discourse, unlike the written one, makes the speaker facilitate perception of the material by various means of speech connectors, including discourse elements.

Definition of Discourse Elements

Connecting elements have different names in academic literature. In particular, Randolph Ouirk (1955) names expressions, such as sort of, you see, you know, I mean, well, etc., as intimacy signals, which allow the listener to feel more at ease, to be closer to the interlocutor. There are also other terms for connecting elements of discourse, such as "linking signals", "fillers in", "discourse markers", "temporizers". There have been few attempts to describe and classify these elements and most have not been continued. As a result, there is not any well-established scientific term. The terminological inconsistency is caused by a multiplicity of approaches to the study of the connecting

elements. Moreover, these terms are used to refer to a different set of units, which is determined by the specific objectives of the researcher.

Most linguists think that discourse connectors are the elements that play an important role in organizing the content and structure of the discourse in addition to their semantic and pragmatic aspects. Their pragmatic essence is to ensure the correct understanding of the discourse. Therefore, the most preferable term, in our opinion, is the term discourse elements proposed by Deborah Schiffrin (1994).

By discourse elements we mean segments of speech that connect at least two phrases. They also reflect the intention of the speaker and his/her reaction towards what he/she is saying. The research found that the group of these elements has, firstly, no fixed boundaries, and secondly, has elements that may be presented by different parts of speech. In our article the group of discourse elements is presented by adverbs (so, now, thus, therefore, anyway, finally, however, though, further, similarly, perhaps, maybe, probably, certainly, (un)fortunately, naturally, evidently, surely, obviously, actually, etc.), interjections (well, oh), numerals (first, second), performative verbs (I think, I'm sure, I suppose, I guess, I agree, I say, I hope, I expect, I mean, I assume, I believe, I remember, I forget, I recall, I daresay, etc.), set expressions (first of all, for example, on the one hand, on the other hand, in addition, at the same time, in other words, in terms of, in general, that sort of thing(s), of course, no doubt, as you know, if you remember, you know, as I said, as I mentioned before, etc.), syntactical constructions (Let's start with..., Let's move on to..., Do you have any questions?, etc.).

The lecture as a genre of academic discourse abounds in these discourse elements. Since a lecture may be quite long in time, it demands various elements in its connection, division and organization. This helps explain the great number of discourse elements in it. It is also the result of spontaneity, oral speech and improvisation.

Study

Research Material and Methodology

The research material for our study was audio recordings of lectures to students who studied English as a foreign language, with lectures in Philology given by three native speakers of English (General American standard of pronunciation). Native speakers are professors at American colleges and universities. In total 6 lectures were recorded; they formed a wide body of research material lasting 7 hours 33 minutes, consisting of 2306 linguistic facts, i.e. discourse elements in context. Later 150 fragments containing various dis-

course elements were chosen and formed a narrow body of research material lasting 40 minutes.

The research on the material was conducted in the following way. First, all the academic discourses - lectures - were recorded, then transposed into their written variants, and finally discourse elements were identified. The following aims of the analysis of academic discourse were formulated:

1. To identify discourse elements in the wide body of research material.

2. To study structural, functional and pragmatic features of discourse elements, in terms of the implementation of the intentions of the speaker.

3. To find during the auditory analysis prosodic features of discourse elements.

To meet these objectives, we used complex methods of research, which included: functional and semantic, formal and structural, pragmatic and auditory types of analyses, questioning of a native speaker, a statistical method for data analysis of linguistic material, scaling and linguistic interpretation of the results.

Phonetic Research

The phonetic research consisted of auditory analysis of all fragments of discourses. Recorded fragments were presented to two auditors. At the preparatory stage, the fragments were given to the auditor, a native speaker, without any special phonetic training but with a philological education. He was to listen to the material, fill in the questionnaire and do the following tasks:

1. Determine whether the recorded speech belongs to the standard of General American pronunciation or not.

2. Point out whether the speech belongs to an educated native speaker or not.

3. Specify what style the recorded speech is of: informational, academic, publicist, oratorical or conversational.

The native speaker easily answered the questions, with the results of the analysis as follows. The speech belonged to academic style, was of General American standard of pronunciation and belonging to an educated native speaker.

The second auditor was a Russian phonetician, fluent in English, phonetically trained and experienced in the analysis of the intonation of oral speech. The main objective of the auditor was the analysis of the intonation patterns of the selected fragments of discourses and determination of prosodic features of discourse elements. The analysis was conducted in terms of scales, terminal tones and pauses. The auditor was asked to:

3.

1. divide the fragments of discourses to syntagms, define the boundaries of syntagms; specify pitch movement, tone level and type of scale, focusing on prosodic features of particular discourse elements;

determine the duration and functional type of pauses, and tempo.

We used the following perceptual gradations of each prosodic feature:

1. Tonelevel:low,medium,high.

2. Terminaltones:

- Low Fall, Mid Fall, High Fall;

- Low Rise, Mid Rise, High Rise;

- Fall-Rise;

- Rise-Fall;

- Rise-Fall-Rise;

- Low Level, Mid Level, High Level.

3. Duration of a pause: very short, short, average, long.

4. Type of a pause: syntactical, emphatic, hesitation, rhetorical.

5. Tempo of speech: slow, average, fast.

6. Loudness: decreased, normal, increased. Prosodic marking was done in accordance with

the method of notation adopted at the Department of English Phonetics at Moscow State Teacher Training University (1997).

Results and Discussion

Scaling

cording to the functions in the discourse. The second feature is their structural characteristic.

Structural analysis has demonstrated that discourse elements have different structure and may be one-word elements (so, now, thus, therefore, anyway, etc.) and predicative phrases (S+P) incorporated into the structure of the academic discourse (if you remember, as I mentioned before, do you have any questions?, etc. ). Thus we found four groups of discourse elements: one-word elements, combinations of meaningful words with auxiliary words, phrases and incorporated phrases. This is shown in table 1.

Table 1 -

Structure of discourse elements

Discourse elements

One-word elements: anyway, first, second, next, however, now, then, well, so, probably, perhaps, etc.

Combinations of meaningful words with auxiliary words: in general, in other words, in terms of, in addition, in a way, in fact, of course, etc.

Phrases: I suppose, I think, I say, all right, I would add, I mean, the idea is, I'm sure. I have a feeling, interesting enough, you know, etc.

Incorporated

phrases: do you follow me?, do you know this term?, have you any thoughts about that?, let's look at the concrete example, let's move on to the next technique, look at the sentence, you have to be careful here, etc.

All discourse elements in the research were scaled, enablingus to classify and sort all the studied elements, which was very necessary given the huge amount of material. All quantitative data obtained was analyzed in accordance with the recommendations of Konstantin Belousov and Natalia Blaznova (2005). Scaling is a form of fixing some features of the studied objects by ordering them in a certain numerical system. All the elements have a certain point, or bar graph index, which reflects the position of the feature on the scale. The scales are based, for example, on the principle of increasing or decreasing the degree of manifestation of the observed feature. In our case, this feature is the frequency of use of various discourse elements. We used the following types of scales: nominative, ordinal and interval.

We found that the structure of discourse elements is also of great importance so that in terms of structure we paid attention to the following features:

1. if discourse elements are used separately (they form a separate syntagm) or not used separately (they are the part of a syntagm) (diagram 1)

I separate I non separate

Nominative Scaling

With the help of nominative scale we classified discourse elements in terms of special features and principles they may have. The first feature is the function they may have. All the elements were classified ac-

Connectors and Pragmatic Elements

Discourse elements have special peculiarities in spoken discourse. The lecturer tries to make discourse easier and more comprehensible for the students since

the students can only listen to the speaker.

Discourse elements include not only elements that organize the discourse structurally but also elements that express the opinion of the speaker and are intended to establish some contact with the audience. That is why we have divided them into two big groups - connecting elements (connectors) and pragmatic elements (diagram 3).

The first group consists of elements that indicate linear connections in discourse, i.e. contextual connections. The second group consists of elements that realize the opposition lecturer-students and thus has elements that either express the opinion of the lecturer or are directed towards the audience and aim to create a collaborative setting between the speaker and the students.

As an example of discourse elements that function in academic discourse let us look at the following fragment:

Diagram 3 Discourse elements

If a writer writes poetry or screenplays as well as fiction that gives me a different idea what to expect than if a writer limits himself to one genre. You follow me? In other words, er some writers do write in all three genres, they write essays, they write poetry, they write fiction, they write scripts for dramas and for television programs. Er my feeling is often the more genres they write the perhaps the better qualified writers they are. Let me give an example, historically. Henry James is a famous 19th century-early 20th century American writer.

The group of pragmatic elements is presented by a direct question to the audience, You follow me? This element is very informal and shows the desire of the lecturer to get into contact with the audience and see how well they understand him. The discourse element, in other words, is one of the most frequently used and has the status of an elaborating element in this context. It belongs to the group of logical connectors. It is also necessary to note that the speech of the lecturer is very logical and consistent. With the help of discourse element, let me give you an example, historically, the lecturer wants to illustrate his opinion. This element also belongs to the group of logical connectors. The fact that the professor uses such elements shows that discourse has institutional character and that it is very important to him that his lecture is well understood by the students..

With the help of an ordinal scale discourse elements were classified as "more frequently used" and "less frequently used". In this scale it does matter in what order the cells in the scale are put. Using this particular scale we managed to arrive at conclusions about varieties of discourse elements and frequency of their use as shown in table 2.

47. Have you heard that term/word? / Do you know that term? / Do you know what the word... means? / Is that term you heard/know? / Is that the word you're clear on? 0.3

63. I don't think 0,2

64. Finally 0,2

65. That's a pattern. / These are patterns. 0,2

/That's another pattern.

We also conducted statistic analysis of language material in terms of average statistic figures (discourse elements). As the result of this analysis we found the most frequently used discourse elements are: so, now, I think, OK, in other words, in terms of, you know, for example, well, I mean, (and) also, anyway, probably, that/it means. The results of this analysis allow us to conclude that there are a special number of discourse elements that are regularly used in this kind of discourse and that they vary in their functions. However the most commonly used are the elements that express result or consequence; shift the topic; clarify the opinion of the speaker (so, now, I think, OK, in other words, in terms of, you know, for example, well, I mean, (and) also, anyway, probably, that/it means). The use of such discourse elements can be explained by the desire of the lecturer to make students understand his ideas and concepts. This pragmatic goal is essential for the professor especially taking into consideration he/she is delivering a lecture to non-native speakers of English.

Interval Scaling

Interval scales enabled us not only to classify discourse elements but also to numerically express and compare them. Thus we received the data about the number of discourse elements and predominance of

their prosodic characteristics. The analysis and interpretation of the data collected proved our hypothesis that the prosodic variations of discourse elements are determined by the intention of the speaker, the complexity of the structure of the elements, their position in the sentence and in the phrase (table 3).

let it sound more natural. All these factors determine prosodic realization of the elements. The intonation is normally the same as the one in the preceding syn-tagm. Very often these elements do not form a separate syntagm (I think, in terms of, probably, maybe). For example,

Wived in'London for ajear.j And I can'still go'back to-London^andvnot

Sometimes discourse elements in this position can form a separate intonation group (44%), separated with pauses and realized with a particular terminal tone. Very often it is Medium Level (44,4%) and Low-Rise (39, 8%). The tempo and loudness are average. For example,

And there're,people^ who haveVlonger vapations|iNamely,ieachers| erj for on't be^teachingjin thevmonths of July andvAugustWost of the,time. |

The quantitative study showed that discourse elements are often used at the beginning of the phrase (63%). They include discourse elements such as: so, now, in other words, well, anyway, yes/yeah, what/all I'm getting/driving at, I mean, (and) also, that/it means, I know. The lecturer uses such elements in the initial position to make contact with the students, to attract some attention to particular ideas and also to use this time to figure out what to say next. Such elements normally form a separate syntagm (69%); the terminal tone is Medium Level; tempo and loudness are average. For example

Because^wha^Nvhat'colleges have 'foundjout^isjthey can>telljhi9toricallyjfrom the>course^who is'likely to 'finish the .program] Tmother wordsi the »higher the/score| - the-more 'likely the 'student has ability to 'handle the university or 'college level .work.J And>so.|thev^end 'not to'take,studentsjwho have Jow .scores. [

31% of discourse elements are used in the middle of the phrase. The most often used elements in this position are: I think, in terms of, you know, for example, probably, as/what we say, I/we would say, maybe. Used in this position they may be ordinary remarks or additions to the main phrase. Or they can be fillers of pauses of hesitation. The speaker casually expresses his/her opinion towards the mentioned facts. He/she may use such elements to make the lecture livelier and

Discourse elements in the final position appear quite seldomly (6%). They are normally used here to attract the attention of the listeners and emphasize the idea mentioned. In this position you can find elements such as: sort/type of thing, and so forth, I don't know, I'm not sure. They usually form a separate intonation group (92%) with Low/Medium-Fall (45, 5%) and Medium Level (20%) terminal tones; average tempo and loudness. For example,

So altogetherjan American employee^starting,out|can expect about fifteen to sixteen 'paid .Jiolidaysj vacation ,time.j>Now| that may_,soundj likeWery 'little by

The analysis of the prosodic characteristics of the incorporated phrases lets us say that these elements are usually marked by high, increasing loudness and slow tempo. The terminal tone depends on their structure and the emotional level of the lecturer. Sometimes they are marked by rhetorical pauses. It all allows us to mark them out in the context and also optimize the interpretation of the lecture. For example,

"'That may be'only a collection ofjmages^just a collection ofjmages^that are

Conclusions and Future Research

The process of interaction between the lecturer and the students and its result are considered in this research as a kind of institutional discourse, particularly academic discourse. There are many discourse elements in this kind of discourse that make it institutional. They also provide cohesion and realize one of

the principles of lectures, that is, a focus on the audience; in our case it is a student audience that studies English as a foreign language. The specific addressee determines special choice of discourse elements and their frequency of use.

The studied elements differ structurally and can perform different functions. The most common function is delimitation and at the same time integration of the fragments of the discourse. Another function can be connected with expressing the personal opinion of the lecture and his/her judgements. That is why we have divided discourse elements in our research into two big groups that are subdivided into smaller groups.

The functions of the discourse elements, their structure, intentions of the speaker and also their position in the phase determine their prosodic features. They are normally marked out in the discourse and thus help the students to comprehend the lecture better. These findings contribute to our understanding of discourse elements representation and their functioning in academic discourse considering specific features of student audience. The obtained results open perspectives for further research on this issue. Interesting and promising, in our opinion, seems a further study of discourse elements, their functional characteristics and prosodic features on the material of different kinds of discourse, as well as different varieties of English.
