- Description: The thesis provides an interpretation of the poem ʺ(Taalstryd)ʺ (Lewendood, p.143) by employing deconstruction theory, particularly as it has been developed by Jacques Derrida. The main assumption is that the text is not a self-sufficient entity, but finds itself in a continually changing relationship with other texts, a relationship described by deconstructionists as intertextuality. This relationship, as it has been described by Julia Kristeva, does not only involve literary works, but also the world-as- text. In chapter one this point of view is illustrated in a discussion around the title of the poem. It is postulated that the title is not a neutral description of a period in the history of the development of the Afrikaans language. Rather, it represents an ideological concept which can be interpreted in various ways. The poem clearly lends itself to an interpretation of "the struggle for the Taal" as a struggle which has manifested itself in many different areas and historical periods within the South African context. In chapter two the discussion of the relationship between language, history and ideology is continued. It is shown how the ʺofficialʺ history represents a one-sided view of Afrikaans as a ʺEuropeanʺ language, greatly ignoring its African component. This representation relies on a logocentric approach to the relationship between language and writing. Breytenbach's poetry, like the writings of Derrida, can be regarded as a "deconstruction" of this approach. The ʺdisseminationʺ of meaning in ʺ(Taalstryd)ʺ is illustrated in terms of the poem's intertextual relationship with Breytenbachʾs ʺPlease don't feed the animalsʺ and Krigeʾs ʺLied van die Fascistiese bomwerpersʺ. Chapter three sets ʺ(Taalstryd)ʺ within the current debate surrounding Afrikaner survival. It is shown how the Afrikaner power base has been established and strengthened by way of legislation, the system of Christian National Education, as well as the creation of a nationalist-orientated history. This power base is currently in a state of crisis, in which different political groupings are continuing the ʺ(Taalstryd)ʺ

- Description: This study investigated the level of self-esteem of black and white high-school students using the Rosenberg self-esteem scale. One hundred and eighty six subjects were used, 63 of them being white while 118 were black. A validation of the Rosenberg scale for the black sample was attempted using a correlation between the scale score and a rating of the subjects by teachers. The results of the study showed no significant difference between the self-esteem levels, while the validation study failed to confirm the validity of the test for black subjects in South Africa. However, the validation study v/as rejected as inconclusive and the results of the comparison accepted as confirmatory of previous research. An incidental positive finding revealed that white males have higher self-esteem than white females,. The theory and past research of self-esteem comparisons between racial groups is reviewed. The conclusion is reached in this study that the concept of self-esteem has outlasted its usefulness in the field of comparisons between racial groups and research of a qualitative nature .can provide further data for the understanding of differences between racial groups. , Thesis (MA) -- Faculty of Humanities, Psychology, 1988

A contribution towards an understanding of the intensive tank culture of an ornamental Cichlid, Aulonocara Baenschi, from Chipoka, Lake Malawi

- Description: The intensive tank culture of ornamental mouthbrooding cichlids poses several problems which limit their aquaculture potential. This project addressed some of these problems for Aulonocara baenschi. The production of juveniles in 2501 aquaria was accelerated when: a) aquaria were equipped with refuges, b) females of less than 70mm in standard length were used as broodstock, c) mouthbrooding females were replaced with gravid females at seven day intervals, and d) embryos were removed from the mouths of females at replacement times for artificial incubation. Two sex ratios also accelerated juvenile production. The sex ratio (male:females) 1:30 yielded the highest spawning returns per tank, and therefore represented the most effective utilization of aquarium space (a critical consideration for the small-scale culturist). Contrastingly, the sex ratio 1:12 yielded the highest clutch sizes and a high percentage female spawning return, and therefore represented the most effective utilization of broodstock (an important consideration for culturists inhibited by financial constraints or having an abundance of culture vessels). The reproductive behaviour of A. baenschi was described. Emphasis was given to aspects of reproduction of relevance to culture, for example; spawning times and seasons, clutch size and its relationship with female size, age and size of sexes at first spawning, embryo development rate and size of first swimming juveniles. The slow growth rate of juveniles, combined with a late attainment of marketable size (± seven months) was a major limitation affecting the cuIture potential of A. baenschi. Two factors favouring the cuIture of this species was the high survival rate recorded for both adults and juveniles, and the comparatively high prices fetched by fish on domestic wholesale markets (R4,00 per fish). It is recommended that A. baenschi should not be cultured exclusively for the relatively small South African ornamental fish market. A more profitable strategy for domestic culturists should involve a major production effort with A. baenschi and other desirable species of Aulonocara (e.g . A. ethelwynnae; A. hansbaenschi; A. stuartgranti & A. maylandi) for foreign markets (in particular, the U.S.A.; Western Europe & Japan). Not only are these markets massive, but prevailing exchange rates of the Rand with these currencies favour such a strategy.

Tholeiitic basalts in Zimbabwe are highly enriched in incompatible trace elements and constitute the "northern province". In contrast, basalts from Lesotho and from the southern segment of the Lebombo monocline have lower or “normal” abundances of these elements and were regarded as a "southern province'. Recent work has established that this change in composition takes place relatively rapidly in the Central Lebombo.

A phenomenological explication of the artistic creative experience of a painter, a writer and a playwright

- Description: The aim of the thesis was to explore two focus questions using the phenomenological approach. Firstly, what it meant to be an artist for three particular artists; a painter, a writer and a playwright. Secondly, what a general explicitation (after Van Kaam, 1958) of the three subjects' artistic creative experience and working processes revealed in essence. The taped data of the three artists were reduced and explored through a number of phenomenological strategies. This led to the formulation of four essential descriptions for each artist, which were based structurally on Van den Berg's experiential categories in A Different Existence. Thus, the essential descriptions reflect each artist's relationship with his/her world, body, fellow people and time. The final step was the achievement of a general extended description. The major conclusion arising from the phenomenological explication is that art affords a way through which artists are able to live an authentic existence. That is, the body and world of the artist are in harmony and the artist's art roots him in the past, is manifest in the present and indicates the future direction of his work. Another conclusion is that the artist is Janus-faced and this enables him/her to balance subjectivity and objectivity in the Lebenswelt and to communicate what he/she sees to others in a healthy way through art. The artist's relationship with world, body, fellow people and with time, is postulated as being qualitatively richer than that of the nonartist. The two focus questions were successfully answered through the research explication and were validated by two independent judges. The viability of the phenomenological approach in the field of artistic creativity was therefore demonstrated. Suggestions for future research were made, one of which was that more phenomenological research aimed at eliciting specific information on the creation of art works might render more information on the artistic creative process.

- Description: Bereavement is the natural human reaction to the death of a significant other. Often the experience of the bereaved person is denied expression in the social context. The aim of this thesis is to examine what it means to have one's bereavement denied by others. The relevant literature was reviewed. Theories which have both reflected and influenced the way the bereaved are perceived in contemporary western society have been discussed. The historical background to changing attitudes towards death was described and the reasons for the "denial of death" were examined . The narcissistic personality in particular was considered . Using the Phenomenological method, a question was formulated to elicit the lived structure of the experience being researched. This was asked of thirteen voluntary subjects who had experienced the denial of their bereavement by others. Five written answers (protocols) were chosen and explicated. The lived structure of the experience can be described as "a profound and fundamental distancing of the world of the bereaved from the world of others." The implications of this for the bereaved person, bereavement support groups, health care professionals, future research and society as a whole were then critically discussed .

Dietary Zn deficiency (< 1·5 mg Zn/kg) but not Zn excess (500 mg Zn/kg) resulted in an increased cAMP concentration in transplanted hepatoma cells. Neither treatment had any effect on the cAMP concentration in regenerating liver or normal resting liver. Both the deficient and excess Zn diets resulted in a small reduction in tumour growth (not statistically significant). The results seem to indicate that the relation investigated in the present study does not apply in the cell line used.

- Description: This thesis attempts a synthesis of two important and fast developing branches of mathematics, namely universal algebra and fuzzy set theory. Given an abstract algebra [X,F] where X is a non-empty set and F is a set of finitary operations on X, a fuzzy algebra [I×,F] is constructed by extending operations on X to that on I×, the set of fuzzy subsets of X (I denotes the unit interval), using Zadeh's extension principle. Homomorphisms between fuzzy algebras are defined and discussed. Fuzzy subalgebras of an algebra are defined to be elements of a fuzzy algebra which respect the extended algebra operations under inclusion of fuzzy subsets. The family of fuzzy subalgebras of an algebra is an algebraic closure system in I×. Thus the set of fuzzy subalgebras is a complete lattice. A fuzzy equivalence relation on a set is defined and a partition of such a relation into a class of fuzzy subsets is derived. Using these ideas, fuzzy functions between sets, fuzzy congruence relations, and fuzzy homomorphisms are defined. The kernels of fuzzy homomorphisms are proved to be fuzzy congruence relations, paving the way for the fuzzy isomorphism theorem. Finally, we sketch some ideas on free fuzzy subalgebras and polynomial algebras. In a nutshell, we can say that this thesis treats the central ideas of universal algebras, namely subalgebras, homomorphisms, equivalence and congruence relations, isomorphism theorems and free algebra in the fuzzy set theory setting

- Description: From Introduction: The study of San rock art has undergone several different phases in approach to the interpretation of art. Two approaches are currently in use. The first emphasises the art as narrative or literal representations of San life and its proponents may be called the "art for art's sake" school. Adherents to the second approach make detailed use of the San ethnography on the belief system of these people and are highly critical of the literalists because they provide no such context. The second approach has rapidly gained ascendancy and replaced the "art for art's sake" school over the last twenty years. The watershed came with the researches of Vinnicombe (1967) in the southern Drakensberg and Maggs (1967) in the Western Cape who both embarked upon programs of research which had quantification and numerical analysis at their core, so that they could present "...some objective observations on a given sample of rock paintings in a particular area..." in order to compare and contrast paintings from geographically different areas. What Vinnicombe's numerical analyses clearly showed was that the eland was the most frequently depicted antelope and that it must have played a fundamental role "...in both the economy and the rellgious beliefs of the painters...", which opened up the search for what those beliefs might be and how they could be related to the rock art itself. In order to understand what the rock art was all about it was recognised that researchers had to meaningfully contextualise the art within the social and religious framework of the artists themselves.

- Description: From Introduction: The study of San rock art has undergone several different phases in approach to the interpretation of art. Two approaches are currently in use. The first emphasises the art as narrative or literal representations of San life and its proponents may be called the "art for art's sake" school. Adherents to the second approach make detailed use of the San ethnography on the belief system of these people and are highly critical of the literalists because they provide no such context. The second approach has rapidly gained ascendancy and replaced the "art for art's sake" school over the last twenty years. The watershed came with the researches of Vinnicombe (1967) in the southern Drakensberg and Maggs (1967) in the Western Cape who both embarked upon programs of research which had quantification and numerical analysis at their core, so that they could present "...some objective observations on a given sample of rock paintings in a particular area..." in order to compare and contrast paintings from geographically different areas. What Vinnicombe's numerical analyses clearly showed was that the eland was the most frequently depicted antelope and that it must have played a fundamental role "...in both the economy and the rellgious beliefs of the painters...", which opened up the search for what those beliefs might be and how they could be related to the rock art itself. In order to understand what the rock art was all about it was recognised that researchers had to meaningfully contextualise the art within the social and religious framework of the artists themselves. Without the provision of such a relevant context, as many different interpretations of the paintings could be made as there were people with imaginations. Such a piecemeal approach provides a meaningless jumble of subjective fancy which tells us something about the interpreters but nothing about the rock art. It is unfortunate that the advent of this explicitly social and anthropological approach marks the end of the amateur as a serious interpreter of San rock art, for the juxtaposition of the ethnography with the rock art requires a proper training in which the intricacies of symbol and metaphor can be recognised.

- Description: Marketing channels have traditionally been examined as commercial conduits the sale objective of which was to facilitate the flow of goods from producer to consumer. This approach emphasized functional and structural aspects of the channel and was primarily concerned with the efficiency of the distribution system. During the last two decades, marketing channels have increasingly been viewed as social systems affected by the behavioural dimensions of power, conflict, roles and communication. The rapid growth of vertical marketing systems with greater authority and interdependence between channel members, have stimulated interest in this field. Nevertheless, research has been limited and characterized by methodological problems and conceptual differences about the definitions of behavioural variables and their relationships. Some attempts have been made to develop an integrated framework within which to conduct research into channel relationships, but the validity and relaibility of these models has not been tested. This research project examined the relationship between the sources of conflict and stages in the conflict process. The sources of conflict were subdivided into attitudinal and structural categories, the latter being concerned with goal differences, the desire for autonomy in the face of interdependence and competition for scarce resources. The conflict process model adopted by the author assumes the existence of stages of latency, feeling, perception, manifestation and aftermath in each conflict episode. The first four were treated as separate behavioural states for which different levels of conflict intensity were measured. In order to provide greater explanatory power to the results of the analysis, the perceptions of two respondent groups were identified, namely the leader group, consisting of channel members responsible for the overall strategic interests of the channel, and the affected group, consisting of channel members who had been adversly affected by the activities of their partners in the channel dyad. In addition, respondents were asked to identify separately, their perceptions of the macro and micro levels of conflict in the four conflict states. The marketing channel for prescription medicines was selected for the study. The focal dyad consisted of retail pharmacy managers and doctors with single respondent perceptual measures being obtained from the retail pharmacy managers. A mail survey of all the retail pharmacy managers in South Africa, South West Africa/Namibia, and the independent homelands conducted in July 1987 resulted in a 40% response rate (1031 returns). Tests indicated statistically significant differences between the perceptual measures representing the sources and stages of conflict, the macro and micro levels of the stages of conflict and between the leader and the non-leader groups and the affected and non-affected groups. A sequential hierarchy in the level of conflict measured in the behavioural states was indicated, with decreasing levels of conflict being identified in states of latency, perception, feeling and manifestations, respectively. An analysis of the results revealed that attitudinal sources of conflict were more important that structural sources in measures of perceptions, feelings and manifestations of conflict behaviour. In the latent conflict state, structural sources assumed greater importance than attitudinal sources. In most of the measures, the sources of conflict were more correlated with perceptions of conflict at the macro level than the micro level. The exception was manifest conflict for which micro conflict levels were more important. The major sources of conflict were differences in perceptions, differences in goals and the lack of autonomy. The leader group indicated a particular concern for attitudinal factors, particularly communication difficulties. The affected group, whilst identifying attitudinal factors as being the most important, was especially concerned with their lack of autonomy from the doctor, rather than the competition for scarce resources which could have been expected. An overall assessment of the level of conflict between retail pharmacy managers and doctors indicated that the channel dyad was relatively free from conflict. Relationships were characterized by a degree of satisfaction, some degree of harmony and little evidence of conflict behaviour.

An analysis of the structural use of music, song and dance in certain novels by West African writers in relation to concepts of time

- Description: The topic of this thesis is time in the West African novel in English and French, and the key approach is that West African time is readily grasped through a study of West African music. Though Western time is not exclusively or only linear, mechanical and exploitative, and African time not exclusively cyclic, synchronic and experiential, yet there is a characteristically African view of time and preferred modes of its employment in West African fiction. The novelists considered here wrote in European languages, yet each was a member of a specific cultural group and concerned to portray the aesthetics of his inheritance, an important aspect of which is the predominance of repetitive formulae, both in music and in oral literature. The Introduction offers an historical survey of some of the main notions of time that have been manifest in the West, and compares them with notions of African time. Chapter One examines the structural use of rhythm and repetition in the novels of Camara Laye. Chapter Two discusses the griot and other traditions of oral literature in the novels of Ayi Kwei Armah and Yambo Ouologuem, novels which are concerned with the griot 's continuing role in the creation and dissemination of historical perspective. Chapter Three analyses Chinua Achebe 's portrayal of the values of pre-colonial life in Igbo society where the role of music is to limit behaviour through the structures of ritual which thus create static/cyclic time. Chapter Four describes the syncretic art-form, 'highlife', as used by novelists such as Wole Soyinka, which, because it is transitory and always changing, underscores the ironies of modern city life. The thesis concludes that the authors discussed above are aware that music, because it is predominantly social in Africa, is a powerful medium for achieving a healing synthesis between the traditional past when communalistic values were binding, and the urban-orientated present with its insistence on individuation and material enrichment.

- Description: This study is a venture in urban history in that although housing has been the subject of a number of recent studies, little attempt has been made within the British urban history framework to give serious study to what lies behind the architectural facade, the material domestic culture of an urban community. An important objective of this study is to examine the material culture of domestic dwellings in early Victorian Grahamstown, also referring to other parts of the Cape Colony. Where possible these facts are related to the occupants of the dwellings. No community, urban or rural, can be divorced from the influences which lie beyond its immediate locality in region or metropol. As a preliminary to this study the urban background of industrial Britain is examined, as are English and Dutch cultural influences on the interiors of Cape homes in general. The occupational stratification and spatial structure of early Victorian Grahamstown are then explored, leading into· a discussion of the material domestic culture of the interiors of Grahamstown dwellings. In the final analysis, this study is an attempt to uncover the character of early Victorian Grahamstown and its possible implications for English cultural influences at the Cape. In so doing, not only what constitutes the domestic material culture of Grahamstown is established, but beyond that, a comparison made with domestic material cultural developments in another colonial, though not frontier, settlement with roots in Georgian and Victorian England, namely Australia.

An examination of the literary quality of two reading schemes

- Description: Learning to read is one of the most crucial life tasks that the young child must acquire whilst in primary school. In modern society, much of what one does is dependant on having the ability to read. While a great deal of research has focused on how children learn to read, relatively little attention has been paid to the literary quality of the material the children are exposed to whilst learning to read. In the past few years I have become increasingly concerned with the number of teachers who use material designed for teaching children to read without being aware of the literary quality of the material. While numerous teachers are aware of the issues surrounding the learning to read debate and use up to date materials to teach reading, far too many accept the material supplied by the school without questioning its literary merit and its impact upon the young reader. This piece of research is an attempt to evaluate the literary quality of two reading schemes currently in use in Cape Education Department schools. The chief conclusion of the research is that the schemes examined fall far short of the standards required for them to be considered good literature. Although the research is limited to two reading schemes, it is hoped that a teacher using other schemes could use the framework supplied in this study to examine the literary quality of the material she is using. Furthermore, the final chapter offers suggestions as to how to replace material of poor literary quality with books of a higher literary standard. On the basis of the above findings it is suggested that there is a need for individual teachers, schools, teacher training institutions and the Cape Education Department to examine the literary quality of reading schemes and books that are used in the process of teaching children to read. It is hoped that this piece of research will create a greater awareness amongst teachers of the literary quality of reading materials and prompt further research into such materials that will be of benefit to the central character in this study; the young child learning to read

An existential phenomenological study of gaining insight into oneself through perceiving another person

- Description: The aim of this study was to examine the structure of the experience of gaining insight into oneself through perceiving another person. Such a one-to-one situation was selected in order to ensure a minimal level of complexity. The researcher conducted a pilot study in order to check whether people could relate such an experience in response to a long and difficult interview question. One female first year student responded from among a group of thirty to whom the question was posed. She was then interviewed. The data appeared acceptable. This was confirmed after the data analysis using the phenomenological-psychological method of textual analysis. The analysis showed that the subject, while comparing herself with the person whom she was with, discovered that she structured her life too rigidly in her attempt to meet the expectations of others. This discovery gave her the opportunity to restructure her approach to her world and to the others whom she had seen in only a narrow and abstracted way. Lengthier interviews were then conducted with a further six potential subjects. These were then transcribed. Two of those subjects, though, were found to have experienced insight through perceiving more than one other person. The data from the four remaining subjects were then analysed using the phenomenological psychological method. The researcher discovered that insight involves a clarity of perception which is achieved when the person becomes aware of clearly differentiated possibilities; these are revealed to him through his intensely reflecting on where he stands in relation to the other person whom he perceives, or in relation to alternatives revealed to him by the other. The polarities that are revealed allow the person to take up a new approach to his world, since the person discovers that his experience has revealed that he has been inauthentic in his muddled concern about others, and this gives the person a perception of truth that he was previously unaware of. These findings were dialogued with the writing of psychologists and philosophers who have written on the subject of becoming aware of oneself in relation to others.

- Description: This study attempts to explore, both theoretically and empirically, death anxiety across the lifespan in Western society. Six elderly women between the ages of 75 and 90 years were interviewed about their current perceptions and attitudes toward their anticipated deaths, and to what extent these perceptions may have altered over the course of the life cycle. It was hypothesized that an acceptance of religion and a belief in an afterlife existence; a sense of having experienced death before, in seeing loved ones die; and a feeling of having lived a meaningful life through the reminiscence of past events would all facilitate an older person's acceptance of anticipated death. An existential phenomenological explication of the protocols revealed that: religion need not necessarily play a major role in this regard; both the life reminiscence process and having experienced death before in seeing loved ones die facilitated acceptance of death; older persons are prepared for death in the sense of experiencing a feeling that their life cycles have been completed; although death may not be feared, many fears of dying are prevalent. It was thus concluded from this study that, although death is not a major preoccupation of the older person, it does still play a significant role in the lives of the elderly in that being aware of impending death allows the older person to regulate her life according to ̕̕̕̕̕ʾtime-left-to-liveʾ

- Description: The aim of the study was to explicate the experience of interracial love relationships between Blacks and Whites in South Africa. As a point of departure, a basic question was established which would elicit the actual experience of this phenomenon. The researcher conducted twelve interviews and chose the six psychologically richest accounts. The researcher then analysed in detail (using the phenomenological method) the resulting protocols comprising the interviews. The researcher then explicated the experience and discovered that interracial love was a historical process of going through a relationship over time. The subjects experienced a particular historical background in the face of which they felt unfulfilled which brought about the potential to search for authenticity in a particular way. The subjects were placed in a situation where interracial love became a possibility. The subjects saw the other as human and fell in love. A new horizon emerged and a learning experience, about themselves and the world, occurred. The element of conflict was always present which was exacerbated by the South African Apartheid system. Subjects experienced fulfillment and disappointment depending on whether or not their historical demand was met. This structure of the experience was dialogued with the writings of existential-phenomenological philosophers and psychologists and also with that of previous research in the context of discussing particular areas of psychological significance such as historical background and Apartheid, racism, alienation, motives for interracial love, love and the universality of human nature and interracial love as a learning experience.

This is achieved by conditional graph rewriting, with full unification as the parameter passing mechanism. The syntax and semantics are described both formally and informally, and examples are offered to support the expressibility claim made above. The language design is of further interest due to its uniformity and the inclusion of a novel mechanism for type inference in the presence of derived type hierarchies

- Description: A new declarative language is presented which captures the expressibility of both logic programming languages and functional languages. This is achieved by conditional graph rewriting, with full unification as the parameter passing mechanism. The syntax and semantics are described both formally and informally, and examples are offered to support the expressibility claim made above. The language design is of further interest due to its uniformity and the inclusion of a novel mechanism for type inference in the presence of derived type hierarchies

- Description: This study involves an investigation into reasons why pupils continue with mathematics after Std 7. The sample, consisting of Std 8 and Std 10 mathematics pupils at six academic, English-medium high schools in Port Elizabeth, had to complete a short questionnaire during the third term of 1985. It was found that most pupils continue with mathematics because of requirements for certain post-matric courses, to improve their career options and for other reasons classified in this investigation as "extrinsic", i.e. reasons that are not directly related to the nature of mathematics. An attempt is made to determine the extent of the pupils' knowledge of the nature of mathematics. Questions relating to the nature of mathematics are poorly answered by almost all of the pupils, thereby suggesting that this aspect of mathematics is sadly neglected in mathematics courses. The suggestion is made that this lack of knowledge of the nature of mathematics is linked to pupils' decisions to continue with the subject. The conclusion is drawn that unless more attention is given to conveying to pupils something of the nature of mathematics, there will be an increasing proportion of pupils who choose to continue with mathematics for the "wrong" reasons. This, in turn, has possible negative implications for mathematics education in general. Attention is also paid to differences re the above in respect of groupings based on standard, mathematical grade, sex, mathematical achievement and type of schooling. Although no conclusive findings are made other than with regard to specific questions, enough evidence of differences in certain of the groupings is produced to warrant further investigation
