- Description: The dominant theme in Regain is that of death leading to rebirth. This dissertation attempts to explore Giono's narrative techniques within this context. No single chapter will be devoted to a specific technique; instead, the various devices used by the author are discussed as they emerge from the structure of the chapters. Justifying the field of study as defined in the "Introduction", the following three chapters outline the passage of life from death to eventual rebirth. With acknowledgement to Frank Kermode, who writes: "A concord of past, present and future three dreams which, as Augustine said, cross in our minds, as in the present of things past, the present of things present, and the present of things future" ¹, the first three chapters bear his terminology for their headings. Chapter One, "The Present of Things Past", deals with Mameche's loss of her husband and son. Chapter Two, "The Present of Things Present", focuses upon Mameche' s realization of Gaubert's departure, and the decision that she must do something to save the dying village of Aubignane. Chapter Three, "The Present of Things Future", sees Mameche setting out in search of a wife for Panturle, and succeeding. This brings to an end Part One of the novel. Interwoven throughout the chapters are paradigms from Greek mythology, rich in universal symbolism, and the author's belief in man's ability to fuse himself with his surroundings. The conclusion summarizes the findings of this study, attempting to show how an analysis of Giono's narrative technique provides an insight into such a novel as Regain. ¹The Sense of an Ending (London: Oxford University Press, 1966), rpt., 1970, p. 50.

Elie Wiesel's fictional universe : the paradox of the mute narrator

- Description: The approach I have chosen for my study is to analyse the narrative techniques in Wiesel's fiction, with particular emphasis on the role of the narrator and listener in the narratives. This will not only highlight aspects of his authorial strategy involving the reader's response to various dimensions of the Holocaust, but will allow an appraisal of the literary merit of Wiesel's novels. The hushed reverence that tends to accompany allusions to Auschwitz and its literature has impeded certain theoretical investigations, with the result that most critical studies undertaken on Wiesel's works have dealt predominantly with themes and content rather than with form. A narrative approach, however, while it accounts for themes, does so within the narrative process of the work. Form and content are examined as interwoven entities in the particular context of an individual work. My decision to adopt this pursuit is based on the conviction that Wiesel's fiction is a significant contribution to the literature of testimony, not only because of its subject matter, but also because of the way in which his narrators unfold their stories with words suspended by silence in the text. The paradox of the mute narrator, the title of my study, is intended to convey the paradoxical quality of Wiesel's fiction and to show how silence, which is manifested in the themes of his work, is concretized by his strategy of entrusting the transmission of the tale to narrators, who, for various reasons have been silenced. A mute by definition cannot emit an articulate sound. A narrator, on the other hand, is a storyteller who is reliant on verbal articulation for communication. This contradiction in terms is dramatized in the novels and is symptomatic of the dilemma of Wiesel's narrators who are compelled to bear testimony through their silence. In my study of Wiesel's fiction, I will follow the chronological sequence in which the novels were written, although I will not be using a developmental approach, except to point out that the trilogy which marks the beginning of his exploration into narrative strategies, and The Testament, the last book I will be dealing with, are a culmination of his previous fictional techniques. While a developmental analysis of his fiction, particularly from a thematic point of view, enables the reader to gain insight into his background, which is important in a comprehensive study of his works, I feel that this avenue of investigation has been competently dealt with by other critics. Ellen Fine's Legacy of Night, one of the first book-length studies of Wiesel, puts forward a convincing argument for examining his fiction in chronological sequence as a kind of serialized journey from being a witness in l'univers concentrationnaire to bearing - witness in a post-Holocaust world. Furthermore, it is possible to trace the direction Wiesel's fiction follows, as in each book the seeds are sown for new ideas which are expanded upon in subsequent books. My discussion, however, will deal with the narrative process of each novel as an individual work in its own particular context. Apart from the trilogy which is examined in one chapter, and The Testament which serves as a conclusion to the study, I have not used cross references to Wiesel's other fiction when analysing specific books. Moreover, I have deliberately avoided including Wiesel's comments on his works and references to them in his essays, interviews and non-fiction writing. The reason for this approach is that I consider each novel to be a separate narrative work which merits an interpretative response that is independent of the comparative criteria that has up to now influenced the assessment of his fiction.

The adsorption of chelating reagents on oxide minerals

- Description: This work constitutes a fundamental study of the interaction between chelating reagents and oxide minerals . The adsorption mechanisms have been elucidated for most of the systems generated by the oxides of copper(II) or iron(III) and chelating reagents octyl hydroxamate, N-phenylbenzohydroxamate, salicylaldoxime, 5-nitrosalicylaldoxime or 8-hydroxyquinoline. The results of the preliminary work on one of the systems, viz. the oxide-hydroxamate system, indicated that the classical type adsorption process, in which the reagent forms a uniform layer of chelate over the oxide surface was not applicable. Rather, the adsorption occurred via the formation of a discrete metal-chelate precipitate at the oxide surface. In order to better understand the associated with copper (II) oxide, adsorption process the oxide was recrystallized to produce a coarser material with a more uniform surface. This allowed the oxide surface to be viewed under the scanning electron microscope and also enabled the relative concentration of "surface" and "bulk" chelate to be assessed. A detailed investigation of the effect of the system variables; pH, conditioning period, concentration, temperature, surface area and dispersing reagent on the rate of precipitation of the copper chelate species of general form, Cu(chel)2' was made. In addition the chemical nature of the adsorbed species and the structural form of the precipitates were determined with the aid of infra-red spectroscopy and the scanning electron microscope. On the basis of these results a model has been formulated for the adsorption processes. In this model the adsorption dissolution, is considered to occur in stages: 1. Oxide dissolution, 2. metal complex formation, 3. Metal chelate precipitation at the oxide surface and 4. “bulk” chelate formation by post-precipitation processes. The precipitation process was examined in more detail by the study of the adsorption of chelate on copper metal. The results of this study showed that it was possible to relate the structural type of precipitate formed, ie. fibrous or platelike, to the degree of supersaturation of the metal complex in solution. Furthermore, it was found that the precipitate structure determined whether it remained attached to the surface or detached. Contact angle measurements of air bubbles on copper metal conditioned with chelate were related to the adsorption results in an attempt to isolate the optimum conditions for flotation of oxide minerals.

- Description: Three-dimensional graphicacy is the part of map work that appears to be the most problematIcal. Bartz (1970) says that thinking and visualising in three-dimensional space is difficult enough, but trying to derive notions in three-dimensions, when you have only seen them as they are represented in distorted two-dimensional fashion, is even more difficult. Yet pupils of geography are required to learn such three-dimensional concepts from the two-dimensional distorted map presentations. The geography teacher has an important educational role to play in promoting graphicacy and Balchin (1965), who coined the term, felt that it should be an essential underpinning of an integrated education. The problem is that children perform badly, teachers are not successfully imparting three-dimensional graphicacy skills and as Board and Taylor (1977) indicate, for some time now it has been fashionable to dismiss maps as being irrelevant or useless in geographical research. This thesis attempts to analyse this reported malady, the problems are exposed and solutions offered. Investigation of the literature, with the aim of clarifying the problems involved, follows four leads. These are the part played by the map as a mode of communication, the physical processes involved in mapwork revealed by work in the realm of neurophysiology, the process of visualisation in the field of perception and psychology, and finally the stage of conceptual development of the mapworker. The state of affairs in South Africa is disclosed by an analysis of teacher-directed literature, of examination syllabuses, of text-book treatment of three-dimensional mapwork in South Africa and overseas, of past examination questions, and finally of teachers' views. Experimental exercises have been executed in an attempt to link the key findings of published research to the local scene. Conclusions are then drawn, and recommendations made for improving three-dimensional graphicacy in South African secondary schools.

- Description: This piece of research is an attempt to evaluate the assessments made by secondary teachers in training of an introductory orientation course offered during the first seven weeks of the 1984 H.D. E. course in the Department of Education of Rhodes University. This course, the About To Teach (ATT) course, was introduced in an attempt to obviate some of the perceived problems that students experience in the initial months of their H.D.E. year. The course was first offered in 1982 and in both 1982 and 1983 it was assessed by the students. The evaluation of the assessments offered in those two years provided much of the background for this in-depth look at student assessments of the 1984 ATT course. Briefly, the course attempts to offer the students a stimulating, meaningful, interesting and enjoyable learning experience which will help them to orientate; prepare them adequately for their first teaching practice and the reception later of the offerings of the core theory discipline of Philosophy, Sociology and Psychology. The course itself is a piece of action research and its underlying assumptions are essentially humanistic in nature. Its planners have attempted to bracket as many assumptions as possible and to espouse only those assumptions which are basically positive in nature. It does not attempt to prescribe or offer any dogma which can or must be assessed in any formal sense; it attempts to meet the students from whatever stages in their development they are at when they arrive to commence their H.D.E. year; and it does not attempt to compel the students in any way whatsoever. It is a course which must stand or fall on its own merits. Since the researcher is himself an involved participant in the process, he felt that the completion of a detailed questionnaire and interviews with a sample of the students would be the most economical and the best means of obtaining data for as objective an analysis as possible. To further obviate the possibility of researcher bias all the responses collected have been included in the appendices so that the reader may satisfy him/herself that the interpretations made and conclusions drawn are reasonable. Briefly, the chief conclusion of this researcher is that the overwhelming majority of the students perceived the course as offering them a meaningful learning experience. In addition, it can be argued that the course is, in effect, a guidance course in that it appears to be preparing students for experiences which they still have to come across . Most are generally critical of other courses offered during the H.D . E. year and many make an appeal for, or suggest, a much more integrated approach along the lines of the ATT course . There is a definite appeal for a coherent H.D.E. experience which is meaningful and 'peoplecentred'. By no stretch of the imagination can the findings of this particular piece of research be generalised to any other context since it is very definitely specific in both context and setting. However the researcher is quietly confident that his conclusions and recommendations make a great deal of sense within the specific context of this study.

- Description: A number of issues in the thesis need to be clarified and will be discussed individually below. The term Third World, which is used in the thesis to describe developing countries in a disadvantageous economic position in relation to developed countries, is unsatisfactory. It is a collective term which combines countries with dissimilar cultures, ideologies and future prospects into one category (De Souza & Porter, 1974). Debate continues whether South Africa can be classified as a First or Third World country (Fair, 1982). Rogerson & Beavon (1980) indicate that South Africa can be described as dichotomous because it reflects characteristics of both First and Third World countries. In comparison De Souza & Porter (1974,1) include South Africa among the Third World countries, because four-fifths of the people have an income that is six times less than the income of the other fifth, and they live in a condition of underdevelopment. Conditions in Fingo Village resemble those described by De Souza & Porter (1974) and hence the results of the Fingo Village survey are compared with similar studies, elsewhere in the Third World. However, it would be naive to assume that Fingo Village is unaffected by development within the core regions of South Africa, which in many instances epitomize the First World. The term informal sector, used throughout the thesis, is also unsatisfactory, and debate continues as theorists attempt to find a more appropriate term. Santos (1979) indicates that the term informal sector is contentious, by placing it in single quotation marks. From the literature survey it emerged that the majority of authors did not follow Santos' convention (1979) and thus it seemed acceptable to use the term, informal sector, without placing it in single quotation marks. Chapter Two deals in-depth with the problem of defining the informal sector, and a working definition for the Fingo Village survey is presented in section 2.4.1. The informal sector embraces a wide diversity of economic activities. Due to the limited time and funds available, it was decided to isolate one aspect of this sector, namely, hawking. Sections 2.3 and 2.7 of Chapter Two indicate that hawking is an exemplary informal sector activity. All the different hawking types could not be given close attention and therefore, for practical purposes, it was decided to select one facet of hawking, namely, fruit and vegetable hawkers. Mobile fruit and vegetable hawkers were excluded from the study as it was impossible, during the mapping survey, to isolate a specific hawking site for each mobile hawker. Furthermore, a mobile hawker could easily be enumerated on more than one occasion, and hence a margin of error would automatically occur in the study. This was another reason for excluding mobile hawkers from the study and merely focusing upon static and semi-static fruit and vegetable hawkers. It is difficult to collect comprehensive quantitative data on informal sector activities (Preston-Whyte et al, 1984). The interviewer has to gain the confidence and trust of the subjects. The interviewer for the Fingo Village survey was a well known local personality and a man of some standing in the Black community. Daniel Sandi was the Secretary, of the Grahamstown Association (GRACA), which was reputed to have the support of the majority of the Black residents in Grahamstown until it was banned under the State of Emergency in July 1985. Daniel Sandi was also known for his contribution in literary circles as an epic poet. His previous experience conducting socio-economic surveys, as a researcher for the Border Council of Churches and as the Teba Research Assistant for the Institute of Social and Economic Research, Rhodes University, was also helpful. Sporadic unrest in the study area, from September 1984 and throughout 1985, prevented further fieldwork from being conducted in Fingo Village.

The historical significance of this structure is to be found in the earliest treatises on painting, Cenninni's treatment of painting as a purely practical matter is in accord with medieval tradition. His recipes are aligned according to the various individual techniques, tempera painting being the most significant to this essay. Practical recipes are interspersed with directions for the representation of various pictorial themes, and in the resultant conglomeration, the subdivisions are discernible only as basic premises. In contrast to him, the Renaissance authors beginning with Alberti make a significant innovation in that they divide their material into a theoretical and a practical part . The inter-relationship of practical and theoretical - aesthetic and technical aspects are un-avoidable when it comes down to realities. This is clearly illustrated in the notes of Leonardo da Vinci. Plans for the organization of the treatise are vaguely formulated .

- Description: Introduction: For approximately the last eight years the Laser Section of the National Physical Research Laboratory (NPRL) has been interested in inter alia, pulsed solid-state lasers and in particular, Nd:YAG. Investigations of various resonator types were undertaken with a view to the improvement of the laser parameters such as output energy, pulse width, beam quality and sensitivity to mirror misalignment. In 1980 a Nd: YAG laser employing a rotating prism Q-switch was constructed (Preussler (1980)). It involves rotating one of the two cavity reflectors so that they are parallel for only a brief instant in time. Typically the prism must rotate at a speed of 20 000 r.p.m. to ensure a single pulse output. Such lasers suffer from the tendency to emit multiple pulses, they are very noisy and they require frequent maintenance because of the short lifetime of the bearings. A resonator employing conventional curved mirrors and an electro-optical Q-switch was constructed in 1980 (Robertson & Preussler (1982)). In 1981 an electro-optically Q-swi tched laser making use of a crossed Porro-prism resonator was investigated due to its relative insensitivity to misalignment of the reflectors compared with the conventional mirror resonator (Nortier (1981)). Improvements in terms of output power, beam divergence and beam quality can be achieved by making use of a so-called unstable resonator. Such a laser has been investigated and is reported on in this study. Chapter 2 provides some background into laser theory and operation while chapter 3 deals with the theory of the unstable resonator. Chapter 4 provides details of the experimental equipment and techniques used in the work and chapter 5 discusses the evaluation of the project and results obtained.

Betterment Planning, upon a rural Black village in the Keiskammahoek Magisterial District of the Ciskei, in South Africa. The project was implemented in the mid-1960s, and involved the re-organisation of the village environment into demarcated arable, grazing and residential areas, which necessitated the villagers moving from their old, scattered residential clusters to several new, concentrated residential areas. This dissertation seeks to trace the consequences of this development project, and particularly the socio-economic consequences of the residential relocation that it involved.

- Description: The general biology of the South African Cliff Swallow Hirundo spilodera was studied over a two year period in the central Orange Free State. This species is highly colonial, nesting mostly on man-made structures such as concrete road bridges. Adult birds were usually faithful to their breeding colony and very few individuals changed colonies. The Cliff Swallow had a surprisingly large vocal repertoire for a swallow and contact calls of the young were individually recognizable. Three species-specific ectoparasites parasitized the Cliff Swallow but none seemed to have a noticeable negative effect on the swallows. Breeding started earlier in larger colonies than in smaller ones and conspecific brood parasitism was a common feature in some colonies. Individual pairs made up to four breeding attempts per season. The findings of this study are compared with the available information on other members of the Hirundinidae and the advantages and costs of Cliff Swallow coloniality are discussed.

- Description: In response to a growing concern over the rising rates of extinction of the world's plants and of habitat destruction, studies of Southern African threatened plants were initiated in the 1970's. These studies, which have largely concentrated on Western Cape flora, led to the publication of "Threatened Plants of Southern Africa" by Hall et al., 1980, which attempted to list as many threatened or possibly threatened species as possible. It was however marred by a lack of recent herbarium records and detailed studies from many parts of the region, the Eastern Cape being one of these. In order to extend these detailed studies to gain a clearer picture of the numbers of threatened species in the Eastern Cape and evaluate the conservation status of Eastern Cape vegetation this project was initiated. Initially lists of possibly threatened and endemic taxa of the Eastern Cape were compiled from various sources. These listed taxa were then checked against herbarium records, all available information being filled onto index cards for filing purposes. This paper-based filing system was then transferred into a computer-based data bank to facilitate the efficient storage and retrieval of information. Results from this data bank show that there are 662 variously threatened plant taxa in the Eastern Cape, many of which fall into temporary categories which need to be clarified by investigation in the field. Primarily based on the above results, a table ranking the various vegetation types into an order of priority for investigations about conservation requirement was developed.Subtropical Thicket was found to be the vegetation type in most need of investigation and so an extensive phytosociological survey was carried out in the Valley Bushveld which forms the major portion of Subtropical Thicket in the Eastern Cape. Twelve sites were sampled for floristic and environmental variables along a rainfall gradient of between 300 mm yr⁻¹ and 1 000 mm yr⁻¹ and along a longitudinal gradient from the Buffalo River in the east to the Gamtoos-Kromme complex in the west. Floristic data W(re analysed using multivariate techniques of classification and ordination. A classification by two-way species indicator analysis revealed the Valley Bushveld to consist of two orders of thicket, the Kaffrarian Succulent Thicket containing the two suborders, Inland Succulent Thicket and the Coastal Succulent Thicket and the Kaffrarian Thicket containing Coastal Kaffrarian Thicket and Inland Kaffrarian Thicket. Ordina tion by detrended correspondence analysis also grouped sites according to these vegetation categories in a sequence along one axis, to which the rainfall gradient could be related. Variables such as diversity indices, numbers of endemics, numbers of threatened taxa and structural features were also extracted from the data and these were correlated with environmental variables by multiple regression analysis. Species richness and the percent woody component w\!re positively correlated with rainfall while endemism and percent succulent component were strongly negatively correlated with rainfall. Most of the other relationships were explained by interrelationships with rainfall. Finally the sites were evaluated according to floristic criteria indicative of conservation value. The Coastal Succulent Thicket appeared to have the highest conservation value mainly owing to high endemism, while Inland Kaffrarian Thicket was also important as it supports a high number of species. The thickets with high conservation value are therefore the thickets of coastal areas in the western parts of the Eastern Cape which receive a low rainfall and the thickets which receive a rainfall in excess of 800 mm. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This study is an investigation of instances of conversational failure in interaction as evidenced by speakers of Black South African English (BSAE) , with a particular focus on the role of prosody in conversational (a)synchrony. The data analysed consist of six conversations, one SAE-SAE (South African English) encounter, four BSAE- SAE encounters and one BSAE- BSAE encounter. After a theoretical framework is set up, the analysis is conducted by means of two triangulation research processes based on Ethnomethodology. The analysis consists of an investigation into selected extracts which participants and informants alike perceived as 'stressful'. An attempt is made to isolate the sources of each instance of pragmatic failure. Prosodic features are found to be important in establishing and maintaining theme and conversational synchrony. But other factors are also involved. The analysis reveals two major influences of asynchrony: deviance in the use of (in order of importance) prosodic, lexical and syntactic cues to discourse functions; and a mismatch in the application of socio-cultural principles guiding conversational behaviour. The study leads into a brief outline of aims, objectives and conversational competence at a tertiary level and concludes with suggestions for further research.

- Description: This study is an investigation of instances of conversational failure in interaction as evidenced by speakers of Black South African English (BSAE) , with a particular focus on the role of prosody in conversational (a)synchrony. The data analysed consist of six conversations, one SAE-SAE (South African English) encounter, four BSAE- SAE encounters and one BSAE- BSAE encounter. After a theoretical framework is set up, the analysis is conducted by means of two triangulation research processes based on Ethnomethodology. The analysis consists of an investigation into selected extracts which participants and informants alike perceived as 'stressful'. An attempt is made to isolate the sources of each instance of pragmatic failure. Prosodic features are found to be important in establishing and maintaining theme and conversational synchrony.

Xhosa narrative : an analysis of the production and linguistic properties of discourse with particular reference to "iintsomi" texts

- Description: Although the areas I intend to investigate are rather diverse, what unites them is a concern for the ancient and fascinating question of the relationship between language and thought. Assumptions concerning the latter are surely latent as the basis for any inquiry into language. One of my general purposes is to give some overt orientation to this problem which is all too often simply glossed over. More particularly, I am also concerned with shaping a new approach to Bantu linguistic inquiry in terms of an emphasis on discourse analysis. In the context of the burgeoning of discourse analysis internationally, the field has been seriously neglected in Southern Africa. Studies of discourse are, we believe, vital to advancing our knowledge of inter-ethnic communication and understanding, an area that cannot be ignored in Southern Africa. In more general terms, I hope that this thesis represents a challenge to linguistic inquiry in ways that we have already outlined above. Most importantly, is that while it appears that most South African linguists are satisfied with adopting a rigid monotheoretical approach, I differ, advocating a multitheoretical perspective. This, I believe, allows a greater and more holistic view not only of the 'data' in question but also in terms of the general nature of inquiry, as well as the 'world' it attempts to describe. The body of this thesis is divided into two sections which reflect the two central concerns we have outlined above. Section A, divided into three chapters, is chiefly concerned with the conceptual basis of Xhosa narrative and its linguistic manifestation. In this section we shall find cause to query and to redefine traditional approaches to the linguistic categories manifest in Xhosa narrative. In section B, also divided into three chapters, we shall be concerned with the development of a theory of narrative production with specific reference to intsomi production. In this section we include an in depth criticism of previous approaches to this problem before developing and applying our own theory. There are two appendices attached to this thesis. The first presents certain tables and figures relevant to chapter 4. while the second includes the narrative texts from which we draw our examples. (Introduction, p. 21-22)

A study of the marine algal epiphyte, Placophora binderi (J. Agardh) J.Agardh (Ceramiales : Rhodophycophyta)

- Description: Placophora binderi can be described as an "obligate epiphyte" as it does not respond well to any culture conditions and is found growing only on other algae in the natural environment. This habit may have arisen as a response to the best available substrate in a harsh environment (Harlin 1971; Moss 1982). Any nutrient transfer which may occur between Placophora binderi and its basiphyte, usually various species of Codium, is probably by diffusion as rhizoids do not penetrate the basiphyte cells but simply lie between the Codium utricles providing better anchorage. A triphasic life history exists with isomorphic gametophyte, carposporophyte and tetrasporophyte generations. The male and female gametophytes are dioecious. This study confirms Scagel's (1953) observations for the development of the juvenile, mature and reproductive thallus. The juvenile develops as an erect polysiphonous thallus which produces a prostrate lobe as an adventitious branch from the basal segments. This prostrate lobe develops into the dorsiventrally flattened mature thallus. Reproductive structures are produced on erect branches which are initiated at the mature thallus margins. The gametophyte develops on evanescent trichoblasts produced on erect reproductive branches while the tetra sporophyte develops within these erect branches. The female gametophyte has a four-celled carpogonial branch with an auxiliary cell forming after fertilisation from the supporting cell. At the electron microscope level several vesicle types were seen in the reproductive organs. In the male, spermatial vesicles are produced which probably aid in release of the spermatia (Kugrens 1980). These are also visible under the light microscope. In carposporogenesis and tetrasporogenesis, three vesicle types are produced. Striated vesicles appear for a short while during the early stages and probably function as protein stores. Fibrillar vesicles are large and visible under the light microscope. These probably act as carbohydrate storage organelles (Triemer and Vasconcelos 1979; Kugrens and West 1973c; Tripodi 1971). Cored vesicles appear late in sporogenesis and probably aid in adhesion once the spores have settled (Chamberlain and Evans 1973; Wetherbee 1978). Carpospores follow the "serial release" type pattern observed in Polysiphonia (Boney 1978). Tetraspores are released singly via a rupture in the tetrasporangial wall as in Ceramium rubrum (Chamberlain and Evans 1973). Both carpospores and tetraspores germinate in the typical bi-polar Ceramium-type pattern described by Dixon (1973)
