- Description: The impetus for using the therapy with J.B. for this study was primarily the challenge inherent in the situation from the moment the parents and J.B. arrived for their family interview and assessment. They had been through many professionals by then, and much medication. They were sceptical of our intervention, since nothing to date had relieved the situation, and J.B. still had outbursts of rage towards his mother, he was still expressing suicidal ideation and anxiety. The challenge was particularly in relation to the mother, who had great difficulty conceptualising J.B. 's problems as being emotional and relational in nature - she was infinitely more comfortable with physiological interpretations of everything. This had the effect on the therapist and the supervisor of frequently reassuring their belief in psychotherapy as the treatment of choice in this case, or if in fact there was a lurking 'disease ' or organic cause to the child's behaviour. The pressure was thus considerable in this respect, despite the fact that the child had been examined physically and nothing found. This study aims to demonstrate the efficacy of psychotherapy, and the changes that took place, with this patient who was previously treated with medication.

- Description: Pupils entering High School for the first time experience many problems of orientation and adjustment. This study arose from the conviction that something could be done to alleviate this time of stress to the benefit of both pupil and school alike. A brief review of literature showed that despite a fair amount of research having been done in Britain and the United States, there is still a dearth of information relating directly to the South African situation. Most transition studies differentiate between factors affecting academic adjustment, those relating to personal adjustment after transfer, and those which involve adjustment to environmental factors. In general studies approached orientation pogrammes from two perspectives - those that handled orientation as an event with its concomitant administrative and practical advantages, and those that saw it to be a process which has more person-focussed advantages. Most researchers agree that each school has its own needs and that the orientation programme should reflect those needs. Many favour a problem-solving approach to the design of any programme and emphasize the need for constant evaluation of the programme to maintain relevance and effectiveness. A low-key investigation into adjustment problems faced by new pupils in the High School was conducted by means of a questionnaire. Three main areas of information were investigated: attitude to school; personal adjustment as indicated by the self-concept; and general impression of Secondary School. The results confirmed that problems of orientation and adjustment are experienced by pupils in the South African Education System and revealed a framework upon which an orientation programme could be based. An overview of existing orientation programme objectives stresses the fact that orientation must be concerned with the total adjustment of the child - personal, academic and environmental - and that, of necessity, it involves the whole family. An orientation programme is outlined and expanded upon in order to provide a framework upon which other programmes could be designed, specific to the particular needs of the schools involved. Finally, certain observations are offered which may lead to a better understanding of the demands of the orientation process

- Description: H. armigera larvae are a key stage for pest management in conmercial irrigated cotton crops in South Africa. Effective survey methods for detecting larval populations in the field require an understanding of the biology of the larvae, particularly their feeding habits. Their feeding is central to the development of pest threshold levels for the implementation of integrated control programmes. This applies to routine surveys for the larvae as well as to the damage they cause. Biological characteristics of the larvae are described with the emphasis on the identification of the larval instars, which were consistently five in number in both field and laboratory populations. The distribution of H. armigera larvae on cotton plants in the field was examined, but was found to more or less random; had there been a clear preference for any height zones or compass direction this would have been an obvious avenue for improving the survey methods currently in use. Details of field and laboratory investigations of the selection of feeding sites by the larvae are given. The study confirmed a clear preference by the larvae for cotton buds, flowers and bolls (in the thesis collectively called "fruiting forms"), over leaves. There were indications that the larvae selected flowers more readily than buds or bolls. This "preference", however, is shown to be of no practical value for refining survey methods. Damage levels to cotton due to B. armigera are discussed. Both direct losses and indirect losses due to the abortion of fruiting forms are considered. These criteria are inadequate since they do not take into account the ability of cotton plants to compensate for these losses. It is concluded that this compensation by cotton plants should be taken into account in further studies of the pest status of B. armigera.

- 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.

- Description: In this study food webs and a case study are used to investigate concepts which university students and high school pupils hold about ecology and the degree to which concept development has taken place at particular educational levels. The sample was drawn from first year zoology students and biology pupils in standards eight and ten. Present data indicate that students and pupils could solve problems involving the interactions of populations only if they were simple enough to be answered using strategies based on the food chain concept. Very few subjects could succesfully determine all the interacting pathways along which effects may be transmitted within a food web. The ability to determine all the pathways along which the effects of a change in population numbers within a community are spread, and to analyse the possible net manifestation of sometimes conflicting forces, requires a clear understanding of the concept of food web. An immature understanding of the food web concept by the subjects of this study is suggested as, in most cases, they identified alternate pathways within the food web when explicitly asked to do so, but did not apply this strategy when asked to solve problems based on the same principle. The case study also revealed immature ecological concepts. Responses by standard eight pupils indicate that the opportunity exists at this level to develop a clear and mature understanding of the concept of food web, while comparison of data provided by the three age groups suggests that if clear conceptual development regarding food webs does not take place at school, misconceptions are likely to persist among first year university students.

- Description: The aquifer of the study area occupies an escarpment and low lying limestone plain, and exhibits a Vaal River type karst. The four dolomitic formations present fall into two distinct aquifer forming types; chert poor units and chert rich units. The chert poor units of the Oaktree and Lyttelton Formations were deposited in a subtidal environment and were probably dolomi tised in a migrating schizohaline environment during basin subsidence and shoreline trangression. The chert rich units of the Monte Christo and Eccles Formations were deposited in the shallow subtidal to supratidal zones and the interbedded chert and dolomites may result from minor cyclical marine trangressions and regressions or be a geochemical response to the periodic flooding of freshwater carbonate and flats and tidal deltas. These fundamental geological differences are reflected in correspondingly different development of karst. Transmissive zones in the chert poor units are generally discrete solution features in massive dolomite, 1 m to 2 m thick. Transmissive zones in the chert rich units comprise thick (up to 60 m) and extremely weathered chert with a high void content resulting from the dissolution of carbonate material. The relative importance of various geological features to the development of the karst was assessed using information from two extensive hydrogeological investigations of the area. From the results it bas been concluded that lithostratigraphy, including the occurrence of palaeokarstic horizons, is the major control of aquifer properties. All other geological features are of lesser importance but may nevertheless be associated with enhanced transmissivi ties in any given unit. Faults and lineaments are the structural features most widely associated with highly transmissive zones. The knowledge gained in this study is applicable elsewhere as the principal hydrogeological characteristics of the study area are common to many of the Chuniespoort Group aquifers in the Pretoria - Witwatersrand - Vereeniging Region.

- Description: The history of the Albania Settlement of Griqualand West is examined from its beginnings in 1866 to its demise in 1878. Albania was very much a product of its time. Nineteenth century British colonial policy was basically expansionist, despite minor fluctuations caused by the various influences affecting it, such as the Free Trade and Mercantilist doctrines, social factors within Britain and events within the colonies themselves. From 1815 colonial settlements were fairly common in British territory, especially after Wakefield had provided a convincing theoretical framework for them. Within South Africa itself there are differing interpretations of what motivated British policy and of the role of the missionaries, while the changing political and economic landscape markedly affected Britain's decisions. British Government settlement schemes were undertaken mainly for social or military reasons, but there were also many settlements founded by land speculators. The economically depressed 1860s hit the Eastern Cape hard and this, combined with the transition to sheep farming, which created considerable land hunger, made the Albania scheme attractive to Eastern Cape farmers. The Griqua people led by Andries Waterboer had made a great effort to establish hegemony north of the Orange River, over the Sotho-Tswana and other Griqua chiefs. By 1866 the attempt had failed and Free State farmers were encroaching onto Nicholas Waterboer's lands. When Waterboer's agent, David Arnot, proposed the establishment of a settlement of Albany men to act as a "Wall of Flesh", Waterboer accepted the idea. Arnot's motivation was also land speculation in an area where diamonds were likely to push up land values. From its inception the settlement was dogged by quarrels, mainly over land, amongst the parties involved - the Griqua, brutally removed to make way for the settlers; the settlers, dissatisfied with the land tenure system and their administration; Arnot; the British and the encroaching Boer farmers . After the 1871 annexation of Griqualand West, into which Albania was absorbed, it took seven years, two Land Commissions, a Land Court and a special Land Claims Commissioner to sort out the tangled claims and bring order to the area and Albania's history to a close.

- Description: The geelbek Atractoscion aeguidens is an important commercial and recreational linefish species along the South African eastern seaboard . Aspects of its biology and population dynamics were investigated using data collected from various sampling sites along the South African east coast and from catch statistics obtained from both the Sea Fisheries Research Institute (Cape Town), and dealer records. The biological aspects studied included age and growth, reproduction and feeding. It was established that A. aeguidens is a fast growing species with a relatively late age at sexual maturity and a 1:1 sex ratio. Feeding studies revealed that it has become specialized to feed on small pelagic fish. The South African geelbek stock consists of three distinct age related sub-populations, each representing a particular phase in the life cycle. The sub-adults (1-4 yrs) occur in the South West Cape and feed predominantly on anchovy, Engraulis capensis, which they follow, moving inshore in summer and offshore in winter. The adults (5-9 yrs) undergo a seasonal inshore migration to Natal where they spawn in spring. The dynamics of this migration are strongly influenced by the annual movement of their principal prey viz. , Sardinops ocellatus, to that region. As a result the geelbek first arrive in Natal during mid winter. Evidence is also presented to suggest that a significant number of "adolescent " fish (4-5 yrs) undergo limited gonad maturation and a partial migration to at least as far as the South East Cape. Spawning appears to occur offshore. It is postulated that eggs and larvae are transported southwards by the peripheral waters of the Agulhas Current. After spawning the adults probably remain offshore and use the current to aid their return to the South and South West Cape, where they spend summer feeding on the Agulhas Bank. Juveniles (<1 yr) first appear in the South East Cape between January and March. They apparently use this region as a nursery area for almost a year before moving southwards to join the sub-adults in the South West Cape. In the South East Cape, the juveniles feed initially on mysids whereafter they switch to anchovies and pilchards. A preliminary stock assessment using yield per recruit and spawner biomass per recruit models, indicated that despite the current legislation the South African geelbek population is already overexploited. This is largely attributed to high rates of fishing mortality of the migratory adult population. Further management recommendations are therefore proposed. These include a size limit (660 mm FL), derived from an investigation of the interrelationship between natural mortality and somatic growth in a theoretical unexploited cohort, as well as a uniform bag limit for all user groups (5 fish per person per day)

The sub-adults (1-4 yrs) occur in the South West Cape and feed predominantly on anchovy, Engraulis capensis, which they follow, moving inshore in summer and offshore in winter. The adults (5-9 yrs) undergo a seasonal inshore migration to Natal where they spawn in spring. The dynamics of this migration are strongly influenced by the annual movement of their principal prey viz. , Sardinops ocellatus, to that region. As a result the geelbek first arrive in Natal during mid winter. Evidence is also presented to suggest that a significant number of "adolescent " fish (4-5 yrs) undergo limited gonad maturation and a partial migration to at least as far as the South East Cape. Spawning appears to occur offshore. It is postulated that eggs and larvae are transported southwards by the peripheral waters of the Agulhas Current. After spawning the adults probably remain offshore and use the current to aid their return to the South and South West Cape, where they spend summer feeding on the Agulhas Bank. Juveniles (<1 yr) first appear in the South East Cape between January and March. They apparently use this region as a nursery area for almost a year before moving southwards to join the sub-adults in the South West Cape. In the South East Cape, the juveniles feed initially on mysids whereafter they switch to anchovies and pilchards. A preliminary stock assessment using yield per recruit and spawner biomass per recruit models, indicated that despite the current legislation the South African geelbek population is already overexploited. This is largely attributed to high rates of fishing mortality of the migratory adult population. Further management recommendations are therefore proposed. These include a size limit (660 mm FL), derived from an investigation of the interrelationship between natural mortality and somatic growth in a theoretical unexploited cohort, as well as a uniform bag limit for all user groups (5 fish per person per day)

- Description: In chapter one of this work, as a preliminary to the formulation of the question that this thesis will attempt to answer, the changing understanding of the part played by the interpreter in the process of interpretation is discussed. This outline begins with the understanding of the role of the interpreter in liberal theology - where he is thought of as one who applies critical methods to the text in a detached and scientific way. After this the hermeneutic spiral is discussed - the formation of this model acknowledges to a greater degree the individual and human part played by the interpreter. This is followed by a brief examination of the most recent theories of interpretation in which meaning is regarded as residing not in the text but in the interpreter himself. The task of this thesis is to determine whether, as these recent theorists suggest, the reader creates meaning instead of reading out what somehow lies in the text itself. The task of this thesis is to ascertain, by studying the interpretationsof John's Prologue by Origen, Luther and Bultmann, whether the text does in fact operate as a series of sign-posts that pOint the interpreter to a destination within his own semantic universe. This may be determined by noting whether or not the contexts, i n the broadest sense, of these interpreters have played a formative part in their interpretations. contextual influences are regarded as existing wherever there is a procedure or meaning in the interpreter's commentary which one expe cts to find there as a result of one's knowledge of the interpreter's life and previous writings. Our research reveals that Orige n, Luther and Bultmann have produced three very different commentaries in which the common denominator is the formative influence of the interpreter's context. Each of these writers has produced an interpretation that is consistent, in both approach and theology, with their previous exegetical and theological thought. This indicates that contextual factors have played a significant part in determining their interpr etations of John 1 :1-18. It would appear that these interpreters have been led to find the meaning of John's Prologue not with reference to any new, unprecedented set of symbols, but with reference to their own, well-worn semantic universes. In the conclusion it is noted that this research appears to support what many modern theorists have said as to the locus of meaning in interpretation. In the conclusion it is also noted that many of the fears raised by these findings - that readers and writers, or speakers and hearers, may become so isolated and trapped in their own thought worlds that any real contact with the outside is impossible - may be groundless. These findings also point to a certain consistency between the interpreters and their communities. This refutes the fears as to the isolation and solitary development of the individual in that it points to a certain community or corporate aspect which plays a part in the development of the indivi dual's semantic universe . , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in

- Description: The musselcracker, Soarodon durbanensis, and the bronze bream, Pachymetopon arande, are important components of rock-angling and spearfishing catches In the Eastern Cape. Aspects of their biology, including age and growth, reproduction, nursery areas and feeding, were Investigated to provide a basis for the rational exploitation of the resource. Both species are slow-growing and long-lived. Growth in S. durbanensls was described by the von Bertalanffy growth equation: Lt(mm) = 1021.2(1-e⁻°.°⁹°°⁽t ⁻° .⁷°⁹⁾). The von Bertalanffy growth model did not describe the total data set in P. grande, but by excluding the zero and one year old fish the data were described by: Lt(mm) = 461.1(1-e⁻°.¹⁵³⁽t ⁺¹.⁶⁴°⁾). Detailed histological examination of gonadal development showed that S. durbanensis and P. grande are rudimentary hermaphrodites. Both species had restricted breeding seasons which coincided with peak exploitation. Results indicated that both species are group spawners with pelagic eggs. Size at 50% maturity in S. durbanensis and P. grande was determined at 350 and 300mm fork length, respectively, corresponding to ages of 4.5 and 5.5 years. Intertidal pools functioned as nursery areas for S. durbanensis during the first year, whereas subtidal waters were more important for larger juveniles. P. grande juveniles were commonly observed on subtidal weed beds to a depth of 10m. A size-related change in the diet of S. durbanensis was observed. The juveniles were omnivorous, feeding predominantly on gastropods, echinoids and chlorophytes. The adults fed on a variety of large, reef-associated invertebrates. P. grande were omnivorous, with macroalgae being the principal dietary component. This species appears to utilise the storage and extracellular carbohydrates of the macroalgae. Results showed that macroalgal degradation by gut endosymbionts and the utilisation of macroalgal epibionts does not appear to occur in this species. A detailed analysis of catch composition and catch per unit of effort In the Port Elizabeth rock-angling fishery and the Eastern Cape spearfishery emphasised the recreational importance of S. durbanensis and P. grande. The localised distribution, slow growth and late maturation in both species results in their being susceptible to over-exploitation in these size-selective fisheries. Current legislation protecting these fish is discussed in relation to the findings of this study and additional management measures are proposed.

- Description: This dissertation proposes that George Herbertʾs poetry may profitably be understood as a sacramental means by which the divine is made present in temporal existence. In order to support this claim, the relation between sacramental symbolism and literary symbolism, particularly Herbertʾs, is examined from a number of perspectives. The symbolic meanings suggested by Herbertʾs title (The Temple), and their relation to sacramentalism are considered in the opening chapter. This includes a consideration of some of the background to the analogical thinking prevalent in both the seventeenth-century and Herbert. It is followed in the second chapter by an examination of some of the modern theories about how literary symbolism may relate to sacramental symbolism, a discussion which is followed by a consideration of this dissertation's argument in relation to modern scholarship. The chapter ends with a reading of ʺThe Flowerʺ. The third chapter discusses the poet's attempt to imitate the divine by ʺcopyingʺ both Scripture and Nature, and this includes a consideration of the allegorical and hieroglyphic modes of thought prevalent in the poems. The concern with imitation encourages an examination of the poet's frequent invitation for God actually to assume the poet's role, and this is the subject of the fourth chapter. The argument suggests that the poet's attempt to ʺsacrificeʺ his own writing may be seen in his concern with corporate imagery and corporate (impersonal) structures. The five ʺAfflictionʺ poems are examined as examples of the first, while structures such as synecdoche and metonymy are examined as examples of the second. The final chapter considers aspects of narrative time in the poems, particularly the sense often evoked of the eternal being imminent in the present. This involves a consideration of both liturgical imagery, and what may be called liturgical structures as they can be seen to operate in the poems. Particular examples of the latter are the relation between the liturgical anamnesis and the poems, as well as certain narrative structures that may be called ʺachronisticʺ.

- Description: Since Truman Capote's In Cold Blood: A True Account of a Multiple Murder and its Consequences was published in 1965, there have been many attempts to define and explain the phenomenon of the "non-fiction novel" as a unified narrative genre. Some of these attempts have been highly theoretical and scholarly, but most have been rather loose definitions referring to an extremely wide range of diverse factual narratives. Over the years, so many different works have been called "non-fiction novels" that it now seems as if the notion of such a unified genre is questionable. Surely it is not generically useful to say that such functionally distinct works as Oscar Lewis's La Vida: A Puerto Rican Family in the Culture of Poverty (1967) and Hunter S. Thompson's Fear and Loathing in Las Vegas: A Savage Journey to the Heart ot the American Dream (1971) belong in the same narrative category. The purpose of this study is to show that many of the works routinely referred to as "non-fiction novels" perform fundamentally different narrative functions and do not belong together in a unified genre. Roman Jakobson's model of communication and his notion of the "dominant function" are used to identify three functional categories into which the narratives discussed in the study logically fall: first, there are predominantly sociological works in which the referential function is the most important element of the communication; second, there are predominantly journalistic works in which the opinions of the writer or emotive function constitute the central narrative concern; and thirdly, we have works performing a dominant novelistic or aesthetic function in the sense that the secondary meanings and themes implied are the most important elements communicated. The thesis follows the following structure. In the introductory chapter, a critique of some of the major generic theories of the "non-fiction novel" as unified genre is offered. The purpose here is not to caricature what are sometimes extremely sophisticated studies. (Indeed, in my own analysis of texts, I am often indebted to the critical insights of the scholars whose theories I question in the introduction.) My purpose is merely to show that the corpus of works each writer refers to can be divided more logically between different dominant narrative functions. The introduction ends with a more detailed explanation of the adaptation of Jakobson's notion of "the dominant" and how it relates to the functional categories identified. Chapter 2 offers analyses of a group of documentary narratives that perform a dominant sociological function but have often been referred to as "non-fiction novels." The chapter starts with an analysis of James Agee's Let Us Now Praise Famous Men (1941), a text widely regarded as the first real American example of the "genre." This is followed by an examination of the anthropological works of Oscar Lewis: Five Families: Mexican Case Studles in the Culture of Poverty (1959), The Children of Sanchez: Autobiography of a Mexican Family (1964), Pedro Martinez: A Mexican Peasant and his Family (1964) and La Vida: A Puerto Rican Family in the Culture of Poverty. I conclude the chapter with an analysis of the recent sociological works of Studs Terkel: Division Street: America (1968), Hard Times: An oral History of the Great Depression (1970) and Working: People talk about what they do all day and how they feel about what they do (1974). In Chapter 3, the notion of subjective participation journalism is explained. This is followed by an analysis of three of the most famous and creative of the works that fall into this functional category: Hunter S. Thompson's Hell's Angels: The Strange and Terrible Saga of an Outlaw Motorcycle Gang (1966), Michael Herr's Vietnam classic, Dispatches (1977), and Norman Mailer's account of a famous protest march, The Armies of the Night: History as a Novel, The Novel as History (1968). Chapter 4 offers a discussion of three works that perform a dominant novelistic function in the realistic tradition of Dostoevski's Crime and Punishment. All three are based on actual murder cases, but the facts of the stories are subordinated to the novelistic themes the author wishes to abstract. They are: Meyer Levin's Compulsion (1957), Mailer's The Executioner's Song (1979) and Capote's In Cold Blood. From this outline, it may appear as if the study is loaded in favour of the sociological works discussed in Chapter 2. This is intentional because, although many critics have referred to them as "non-fiction novels", very little systematic and detailed analysis of these works as a corpus has been forthcoming. This long chapter is an attempt to redress the balance.

- Description: This study comprises an investigation of the source and supply of coarse sediment input to a semi-arid channel reach. Despite a growing body of lIterature documentIng research of various aspects of sediment response in semi-arId areas, few studies attempt to integrate processes active in specific source areas wIth sediment supply to the channel. Detailed In the present study is an account of the processes active in the study area, identifIcation of source environments, a discussion of some of the factors affecting supply, a comparison of the effectiveness of gravItatIonal and fluvIal supply processes and an estImatIon of the time sequence of sediment supply to and removal from a channel reach. The above aspects of sediment supply are embodied In the aims set for the study. The study is conceptualIsed withIn the framework of a coarse sedIment supply model. The model is formulated from supporting literature and tested in the light of the results obtained through an investigation of the above aspects of sediment supply in the specIfic study area. The model is prImarily a qualitative one and the data collected intended to strengthen the qualitative nature of the model, while at the same time add at least some measure of quantification. Several reasons for studyIng coarse sediment behavIour in semI-arid areas are identIfied and include the need to improve the present lack of understanding of the relatIonship between supply and removal of sediment, the temporal dIstributIon of sediment discharge and the relatIve contrIbutions of coarse sediment to the overall load of rivers. The study area is located within the semi-arid Ecca basin north-east of Grahamstown. A specifIc channel reach is chosen withIn a sub-catchment (catchment B) of the Ecca catchment area as it has a variety of channel bank environments, is accessible through the entire reach, and the proximity of a raingauge and flow measurIng weir provide the necessary hydrometeorological inputs. The methods of observing sediment response from five data collection sites Include the use of slope or bank base sediment traps, erosion pins, tracer particle monitoring. sequential photographic surveys, and channel bed surface profile surveys. Hydrometeorological data is provided by records drawn from the data bank at the Hydrological Research Unit. Rhodes University. All rainfall records as well as channel flow data are available in the form of continuous records. Rainfall amount and intensity for any period could be extracted from these records. Data collection is confined to a period of two years, during which time the study area was visited on an approximate monthly basis. The index of erosivity (EI₃₀) could also be calculated from the hydrometeorological records and has been used as an integrated measure of rainfall intensity over the monthly period between site visits. The results are presented on a sample day for sample day basis. The sediment response data together with hydrological data is represented graphically for each sample day, of which there were nineteen. Discussion and interpretation of the results is left to a separate chapter. The interpretation of the results are based largely upon graphical representation of data time series and of interrelationships between some of the variables measured. The limited number of sample days together with the assumed auto correlation present in much of the data precluded the use of simple statistical testing procedures. The use of more complex procedures is not considered worthwhile and is unlikely to add to the interpretation of the results. Bedrock weathering is found to be a fairly active producer of coarse sediment on exposed shale bedrock outcrops through which sections of the channel are cut. The transport of the weathered detritus to the channel is attributed to a combination of gravitational and fluvial transport processes, with each process dominating at different times, depending on the magnitude of the climatic input. A tentative comparison of the effectiveness of the two processes reveals that both are capable of transporting similar amounts of sediment but on different time scales. The trends of sediment supply from the various bank environments display remarkable similarity , suggesting a measure of consistency of response to climatic input through the entire reach. Source areas of coarse sediment identified were limited to a small percentage of the total valley area and consisted almost entirely of the immediate channel environment. A tributary gully appears to be an important source of coarse sediment during fluvially dominated supply episodes, while the channel banks supply sediment on a quasi-continuous basis. The total yields for each source environment were extrapolated from the sampled amounts, revealing that channel banks are the predominant source environments. An attempt is made to assess the role of various factors which might affect sediment supply. The factors include rainfall amount and intensity, channel flow, geology/lithology, dip of strata, aspect of channel banks and size of weathered material. The findings, though not conclusive, do give some indication of the role of the above factors. It is suggested though that this particular aspect of sediment supply receive further attention in future research. Discussion on the time sequence of supply to and removal from the channel draws attention to a pulse- like movement of sediment 'waves' through the channel, and two scales of removal-accumulation cycles are identified. Finally the validity of the model is assessed and with the exception of a tributary inflow process not envisaged in the original model, is found to be an accurate representation of sediment supply in semi-arid areas, in both its static and dynamic phases. The suggestion is offered that future research on the sediment supply system, in all climatic regimes, can be conceptualised within the context of the basic model proposed in the present study. Specific components of the model should be quantified by numerous individual research efforts, and in this way, serve to build up the model into a widely applicable tool with which to interpret sediment supply

- Description: This study comprises an investigation of the source and supply of coarse sediment input to a semi-arid channel reach. Despite a growing body of lIterature documentIng research of various aspects of sediment response in semi-arId areas, few studies attempt to integrate processes active in specific source areas wIth sediment supply to the channel. Detailed In the present study is an account of the processes active in the study area, identifIcation of source environments, a discussion of some of the factors affecting supply, a comparison of the effectiveness of gravItatIonal and fluvIal supply processes and an estImatIon of the time sequence of sediment supply to and removal from a channel reach. The above aspects of sediment supply are embodied In the aims set for the study. The study is conceptualIsed withIn the framework of a coarse sedIment supply model. The model is formulated from supporting literature and tested in the light of the results obtained through an investigation of the above aspects of sediment supply in the specIfic study area. The model is prImarily a qualitative one and the data collected intended to strengthen the qualitative nature of the model, while at the same time add at least some measure of quantification. Several reasons for studyIng coarse sediment behavIour in semI-arid areas are identIfied and include the need to improve the present lack of understanding of the relatIonship between supply and removal of sediment, the temporal dIstributIon of sediment discharge and the relatIve contrIbutions of coarse sediment to the overall load of rivers. The study area is located within the semi-arid Ecca basin north-east of Grahamstown. A specifIc channel reach is chosen withIn a sub-catchment (catchment B) of the Ecca catchment area as it has a variety of channel bank environments, is accessible through the entire reach, and the proximity of a raingauge and flow measurIng weir provide the necessary hydrometeorological inputs. The methods of observing sediment response from five data collection sites Include the use of slope or bank base sediment traps, erosion pins, tracer particle monitoring. sequential photographic surveys, and channel bed surface profile surveys. Hydrometeorological data is provided by records drawn from the data bank at the Hydrological Research Unit. Rhodes University. All rainfall records as well as channel flow data are available in the form of continuous records. Rainfall amount and intensity for any period could be extracted from these records. Data collection is confined to a period of two years, during which time the study area was visited on an approximate monthly basis. The index of erosivity (EI₃₀) could also be calculated from the hydrometeorological records and has been used as an integrated measure of rainfall intensity over the monthly period between site visits. The results are presented on a sample day for sample day basis. The sediment response data together with hydrological data is represented graphically for each sample day, of which there were nineteen. Discussion and interpretation of the results is left to a separate chapter. The interpretation of the results are based largely upon graphical representation of data time series and of interrelationships between some of the variables measured. The limited number of sample days together with the assumed auto correlation present in much of the data precluded the use of simple statistical testing procedures. The use of more complex procedures is not considered worthwhile and is unlikely to add to the interpretation of the results. Bedrock weathering is found to be a fairly active producer of coarse sediment on exposed shale bedrock outcrops through which sections of the channel are cut. The transport of the weathered detritus to the channel is attributed to a combination of gravitational and fluvial transport processes, with each process dominating at different times, depending on the magnitude of the climatic input. A tentative comparison of the effectiveness of the two processes reveals that both are capable of transporting similar amounts of sediment but on different time scales. The trends of sediment supply from the various bank environments display remarkable similarity , suggesting a measure of consistency of response to climatic input through the entire reach. Source areas of coarse sediment identified were limited to a small percentage of the total valley area and consisted almost entirely of the immediate channel environment. A tributary gully appears to be an important source of coarse sediment during fluvially dominated supply episodes, while the channel banks supply sediment on a quasi-continuous basis. The total yields for each source environment were extrapolated from the sampled amounts, revealing that channel banks are the predominant source environments. An attempt is made to assess the role of various factors which might affect sediment supply. The factors include rainfall amount and intensity, channel flow, geology/lithology, dip of strata, aspect of channel banks and size of weathered material. The findings, though not conclusive, do give some indication of the role of the above factors. It is suggested though that this particular aspect of sediment supply receive further attention in future research. Discussion on the time sequence of supply to and removal from the channel draws attention to a pulse- like movement of sediment 'waves' through the channel, and two scales of removal-accumulation cycles are identified. Finally the validity of the model is assessed and with the exception of a tributary inflow process not envisaged in the original model, is found to be an accurate representation of sediment supply in semi-arid areas, in both its static and dynamic phases. The suggestion is offered that future research on the sediment supply system, in all climatic regimes, can be conceptualised within the context of the basic model proposed in the present study. Specific components of the model should be quantified by numerous individual research efforts, and in this way, serve to build up the model into a widely applicable tool with which to interpret sediment supply

- Description: Chapter one suggests thet trade and merchant capital, which were crucial to Port Elizabeth's economic development during the nineteenth century, was subsumed by the rise of manufactures and industrial capital after the First World War. Industrial expansion was cut short by the post-war recession, which caused un- and underemployment. The black worker, who experienced a severe loss in real earnings on account of the increased cost of living, became involved in a struggle with employers for wage increases. Chapter two shows how the policy of segregation was applied in Port Elizabeth, which meant that the workers were subjected to an increasing degree of control and regulation of their daily lives. The conditions of reproduction in the black townships fostered inter-racial and cross-class mobilisation which culminated in the formation of a general labour union, the Port Elizabeth Industrial and Commercial Workers' Union (PEICWU). Chapter three will suggest links between the tradition in Port Elizabeth of worker resistance and the unionisation of black workers in the post-war period. Thus, the first three chapters attempt to provide a historical perspective for analysing the underlying causes of the 1920 Port Elizabeth disturbances. The immediate cause of the disturbances was the arrest of the Union leader, Masabalala, after he called for a general strike. Chapter four will show how the intervention of the local authorities provoked a spontaneous act of defiance on the part of Union members. A demonstration outside the Baakens Street Police Station to demand the release of Masabalala, precipitated the tragic shootings of 23 October 1920. The repressive violence which left 22 dead (with two further deaths resulting indirectly from the incident) was unprecedented in South African history. The resolution of the crisis brought the workers no nearer to obtaining a reasonable settlement of the wage issue. If anything, the resolve of employers to deny wage demands was hardened by the actions of the local authorities, who attributed the disturbances to ' agitation '. Such thinly-disguised justifications of the shootings by the dominant classes, however, provoked recriminations from other quarters. Chapter five examines the legal and political ramifications of the Port Elizabeth shootings. The circumstances of the shootings prompted the Smuts Government to appoint a Commission of Enquiry in the face of public pressure. The Commission found that the Police and vigilantes were largely to blame for the high death toll. But the Government's 'whitewash' of the findings could not absolve the Police from culpability entirely, nor could it sidestep its own responsibility and liability to victims of the shootings. Finally, in Chapter six, an attempt will be made to assess the long term impact of the shootings on the PElCU and the black labour movement in Port Elizabeth generally. The outcome of the episode was a victory for employers, which dealt a body blow to worker organisation which only became resurgent in the 1950s.

- Description: Lovedale was founded by the Glasgow Missionary Society as an eduational centre for Africans. Education was to be adapted to the lives of the Africans which would be a departure from the English classical tradition. This meant that emphasis was placed on vocational training and that academic education focussed on the study of English rather than the Classics. But the importance of mother-tongue education was also stressed. The missionaries placed emphasis on village education, whereby the African would be taught skills and crafts that would be useful to him in life. Education, they argued, should also aim at character-training and at spreading the Christian message. They also wanted to see co-operation between the Church and the State in the education of the African. Vocational education was designed to create African artisans who would be able to compete with Whites; but it also aimed at emphasizing the importance of industry in building up character. The Lovedale Press illustrates vocational training in progress, dealing with the difficulties that arose when African printers came into competition with Whites. But the missionaries also used the Press to propagate the Christian message and to promote African literature. An ideological rift began to open up between the missions and the new Black political beliefs of the Second World War. This led to the Lovedale Riot which is considered in the broader framework of sociopolitical unrest within the country. After the 1948 Election an ideological rift also developed between the missions and the State. This study concludes by examining the introduction of the Bantu Education Act and the Lovedale response to this. It was felt that although Bantu Education threatened to undermine their educational endeavour, they should nevertheless cooperate with the system in order to save what they had built up.

- Description: Phenylpropanolamine (PPA), a synthetic sympathomimetic amine structurally related to ephedrine has been widely used over t he past 40 years as a nasal decongestant and appetite suppressant. It has been the focus of much controversy concerning the efficacy of the drug in its use as an anorectic agent, and due to the side effects caused by the higher doses of PPA required for appetite suppression. Although extensively used, there is little information concerning the determination of PPA in biological fluids and on the pharmacokinetics of this drug. An adaptation of a published high-performance liquid chromatographic (HPLC) assay for PPA in serum and urine using U.V. detection at 210 nm is presented. PPA was separated in the reversed phase mode. The method has a limit of sensitivity of 5.0 ng/mL and 10.0 ng/mL in serum and urine respectively. Serum concentration data following a single 25 mg dose of phenylpropanolamine in human volunteers demonstrate the application of the analytical method for bioavailability and pharmacokinetic studies. After the administration of 25 mg, 50 mg or 100 mg PPA.HCl solutions to 5 human volunteers, a dose proportionality study demonstrated that PPA appears to exhibit linear kinetics. Linear one body compartment kinetics were assumed and the wagner-Nelson method used to transform in vivo serum data to absorption plots. The serum data were fitted to a model using nonlinear regression techniques to characterize the pharmacokinetic processes of PPA. The absorption of phenylpropanolamine appears to be discontinuous and the drug seems to favour a two body compartment model. The pharmacokinetic parameters obtained from a steady state study using multiple dosing of PPA.HCl solutions compared with those found from previous studies after the administration of sustained-release formulations. A plasma protein binding study using equilibrium dialysis demonstrated that PPA is not highly protein bound in the blood.

- 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

- 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 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

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
