- Description: The tourism sector in Zanzibar Tanzania has emerged strongly in the past 15 years, helping the development of other Industries that support it. As a result, Industries such as telecommunication, IT, transport and hospitality have also emerged recently. It is, however, speculated that organizations in the tourism sector in Zanzibar generally lack the effective performance that is required of them to compete in the contemporary complex and turbulent market environment. This research thus set out to explore and diagnose the organizational effectiveness of the accommodation units of the tourism sector in Zanzibar. The research had specific objectives of diagnosing and finding the gap between the current and the optimal organizational performance in two particular units of accommodation as well as determining the factors affecting organizational performance in these units. The study furthermore set out to recommend implementation of suitable intervention activities to improve organizational performance in the units analyzed. In order to achieve the above objectives the research deployed an action research strategy with the Weisbord’s six box model as a framework to diagnose two five star grade accommodation units in Zanzibar. A qualitative method was used to collect data. Key findings of the research are briefly presented below: - The service output of the accommodation units analyzed was not very consistent and fell short of the expectation of their customers. This showed a gap in terms of the organizations’ performance. - Factors affecting organizational effectiveness were found to be mainly in the Purpose and Rewards functions of the organizations. - The specific areas in the Purpose function that appeared to have substantial problems were: -- Goals of the organization were not clearly stated -- Employees did not understand the purpose of the organization -- Employees were not involved in deciding their work unit goals -- Employees were not in agreement with the goals of their work units. -- Employees did not understand priorities of the organization The specific areas in the Reward function that appeared to have substantial problems were: -- The pay scale and benefits of the organization did not treat employees equitably. -- Employees felt that the salary they received was not commensurate with the jobs they performed. -- Not all tasks to be accomplished were associated with incentives. Following the diagnostics findings above, the research suggested the following intervention activities that could possibly help to address the above mentioned problems: - A Management by Objectives (MBO) process was suggested to redress the problems indicated in the Purpose function. This would help to set clearly agreed goals at all levels of the organizations. Employees and resources would then be directed towards achieving these goals that would enable the organizations to perform more effectively. - Revision of the current reward system was suggested to redress the problems indicated in the Reward function. The reward system should be implemented in a manner that creates a feeling of both internal as well as external (market) equity among employees. Furthermore, rewards should be linked to performance in order to direct behaviour and motivation among employees. The performance based reward system can also help to achieve the MBO process proposed above since rewards will be designated for achievement of individual, departmental and finally organizational objectives, thus increasing organizational effectiveness.

- Description: South Africa is no longer a pariah state and has been fully integrated into the global family of nations. With the country’s accession to multilateral agreements like the World Trade Organization (WTO), there has been pressure on the government to abandon its hitherto protectionist trade regime in favour of free and fair trade. Trade liberalisation has had profound implications for the country’s manufacturing sector in general, and the automotive industry in particular, which has seen tariff protection radically slashed and import restrictions greatly eased. Not only has the market share of domestic producers fallen, but increases in exports have to date not matched those of imports. As a result there has been a deterioration in the sector’s balance of trade and a reduction in employment levels, at a time when the country desperately needs to create new jobs. Recent developments, however, suggest that this scenario may be set to change. The thesis applies orthodox neoclassical and heterodox approaches to trade policy to an assessment of the likely economic impact of trade liberalisation on the automotive industry in the Eastern Cape, and by extension nationally. The thesis argues that reliance on orthodox trade theory to inform the direction of trade policy, especially in a developing country context, is unlikely to bring about an adequate increase in the level of exports and employment. This is because liberalisation of the import regime is likely to increase import levels without necessarily stimulating export levels, a scenario which serves to negate the presupposed benefits of liberalisation. The study uses information from surveys conducted on both motor vehicle assemblers and component manufacturing firms to investigate the effect of trade liberalisation on the sector in the Province and finds that, by and large, the motor assemblers have not fared as badly as expected and have in fact positioned themselves to export more vehicles and components. The components sector has had to contend with increased competition from cheaper imports. The thesis, while acknowledging that, as far as possible, free trade is an optimal position, nonetheless argues that governments still have an important role to play in the promotion of industrialisation. The scope of government intervention should, however, be limited to selective interventions which are aimed at counteracting market failure and facilitating innovation and the diffusion of technological know-how. The thesis argues that institution of supply side measures, such as the encouragement of research and development (R&D), skills development and industrial training, is necessary for sustained growth in the manufacturing sector to be realised. The thesis also finds that, contrary to expectations, the liberalisation of the automotive sector has not had the desired effects. Despite an increase in the value of automotive exports and an overall trend towards reduced net foreign exchange usage, employment levels are on the decline. The thesis also finds that without major export initiatives by both motor vehicle assemblers and component manufacturers, the future of the industry will be placed in jeopardy, especially with reduced protection and incentives.

- Description: Human African Trypanosomiasis (HAT), also known as sleeping sickness, is a fatal chronic disease that is caused by flagellated protozoans, Trypanosoma brucei gambiense and Trypanosoma brucei rhodesiense. HAT is spread by a bite from an infected tsetse fly of the Glosina genus. Up to 60 million people in 36 countries in sub-Saharan Africa are at a risk of infection from HAT with up to 30 000 deaths reported every year. Current chemotherapy for HAT is insufficient since the available drugs exhibit unacceptable side effects (toxicity) and parasite resistance. Novel treatments and approaches for development of specific and more potent drugs for HAT are therefore required. One approach is to target vital proteins that are essential to the life cycle of the parasite. The main interest of this study is to explore Trypanosoma brucei cathepsin B-like protease (TbCatB) structural and functional properties with the primary goal of discovering non peptide small molecule inhibitors of TbCatB using bioinformatics approaches. TbCatB is a papain family C1 cysteine protease which belongs to clan CA group and it has emerged as a potential HAT drug target. Papain family cysteine proteases of Clan CA group of Trypanosoma brucei (rhodesain and TbCatB) have demonstrated potential as chemotherapeutic targets using synthetic protease inhibitors like Z-Phe-Ala-CHN2 to kill the parasite in vitro and in vivo. TbCatB has been identified as the essential cysteine protease of T. brucei since mRNA silencing of TbCatB killed the parasite and resulted in a cure in mice infected with T. brucei while mRNA silencing of rhodesain only extended mice life. TbCatB is therefore a promising drug target against HAT and the discovery and development of compounds that can selectively inhibit TbCatB without posing any danger to the human host represent a great therapeutic solution for treatment of HAT. To understand protein-inhibitor interactions, useful information can be obtained from high resolution protease-inhibitor crystal structure complexes. This study aims to use bioinformatics approaches to carry out comparative sequence, structural and functional analysis of TbCatB protease and its homologs from T. congolense, T, cruzi, T. vivax and H. sapien as well as to identify non-peptide small molecule inhibitors of TbCatB cysteine proteases from natural compounds of South African origin. Sequences of TbCatB (PDB ID: 3HHI) homologs were retrieved by a BLAST search. Human cathepsin B (PDB ID: 3CBJ) was selected from a list of templates for homology modelling found by HHpred. MODELLER version 9.10 program was used to generate a hundred models for T. congolense, T, cruzi and T. vivax cathepsin B like proteases using 3HHI and 3CBJ as templates. The best models were chosen based on their low DOPE Z scores before validation using MetaMQAPII, ANOLEA, PROCHECK and QMEAN6. The DOPE Z scores and the RMSD (RMS) values of the calculated models indicate that the models are of acceptable energy (stability) and fold (conformation). Results from the different MQAPs indicate the models are of acceptable quality and they can be used for docking studies. High throughput screening of SANCDB using AutoDock Vina revealed nine compounds, SANC00 478, 479, 480, 481, 482, 488, 489, 490 and 491, having a strong affinity for Trypanosoma spp. cathepsin B proteases than HsCatB. SANC00488 has the strongest binding to Trypanosoma spp. cathepsin B proteases and the weakest binding to HsCatB protease. Molecular dynamics (MD) simulations show that the complexes between SANC00488 and TbCatB, TcCatB, TcrCatB and TvCatB are stable and do not come apart during simulation. The complex between this compound and HsCatB however is unstable and comes apart during simulation. Residues that are important for the stability of SANC00488-TbCatB complex are Gly328 of the S2 subsite, Phe208, and Ala256. In conclusion SANC00488 is a good candidate for development of a drug against HAT.

- Description: The aim of this study is to investigate why well planned policies are not getting implemented as intended. The study was conducted in the offices of Amathole District Municipality (ADM) in the Eastern Cape Province, including the cooperative project in Alice as one of the projects that was coordinated by the ADM. Concerning the research design and methodology, a qualitative research design was used. The data collection process involved conducting unstructured interviews with the officers from the Amathole District Municipality office (the ADM officers / the municipality officers) and the members of cooperative projects (cooperatives/projects). Mainly, an ethnographic approach was used; it involved embracing participant observation in the ADM offices for approximately 6 months. As the researcher, I participated as one of the ADM’s officers in different activities, namely: attending meetings and one workshop, and accompanying the development officer while conducting an observation of various projects in Butterworth. The findings in the study disclose that the disjuncture between policy planning and implementation may be attributed to 4 factors, which are associated with the ADM office as the development agency for the Amathole region. These are: the incapability to respond to policy implementation complexities, failure to exploit policy implementation complexities as learning opportunities, the insufficient understanding of ‘process monitoring’ as a tool that could be integrated in projects management, as well as the execution of policy implementation in the absence of policy documents as a guide in implementation processes. Moreover, these factors are examined as being related to each other, and they will be discussed in detail in the course of the thesis.

- Description: This thesis provides a sociological understanding of how conventional knowledge of sexuality negates the identity formation of black gay men in contemporary South Africa. It investigates the coming out experiences of six black gay men in order to reveal the disjunctures between being black and being gay. The theoretical formation of disjuncture is pursued through examining a number of sociological, historical, psychoanalytical, and feminist approaches to identity, sexuality, and society; featuring specifically the theories of George Herbert Mead, Michel Foucault, and Judith Butler. The chosen research paradigm is symbolic interactionism, postulating both „pragmatist‟ and „empiricist‟ trends that lead to both interactionist and structuralist forms of argumentation. The interactionist approach to sexuality is central to the deconstruction of sexual conventions. It involves conceptualising modern sexuality in the landscapes of African colonial history and the global gay and lesbian movement. The prescribed literature on homosexuality is thus reviewed in conjunction with the South African gay and lesbian struggle, so as to spawn themes and perspectives for conducting life story interviews. The use of the life story interview favours the participants‟ own view of the studied phenomenon, yet aims to depict the structural influence on homosexual identification. Following the qualitative research tradition, the data analysis is based on the interpretation of narratives. It illustrates interpersonal relationships and microscopic experiences that lead to the self-acceptance and self-actualisation of homosexuality. Within these processes, various disjunctures that exist between the cultural sanction of lifestyle and individual choice, between parents and children, between religious belief and personal desires, and between gender identity and sexual orientation are disclosed. The findings are associated with the historical transformation of masculinity in South Africa, sex role performance, and the heterosexualisation of desire. The solution to the proposed research problem is discussed through concepts of socialisation and gender conformity.

- Description: The present study investigated the semantic classification of the Setswana noun class system. This enquiry falls under the broad area of the noun classification system in Bantu languages, psycholinguistics and lexicogrpahy. Specifically it explores the basis of noun classification in Setswana making indications that Setswana noun classification is based on a partial semantic classification. Data for the study was drawn from the Setswana Oxford Dictionary. Sixty Setswana nouns, from class 1, 3, 5, and 7, were selected and analysed and then grouped into semantic categories (i.e., PERSON, DEROGATION, TRANSPORATION and so forth). The study adopted Kgukutli’s (1994) semantic classification in performing the dictionary analysis. The rest of the data was drawn from the intuitions of thirty-nine contemporary speakers of Setswana, with the aid of a linguistic test which was fashioned according to Selvik’s (2001) psycholinguistic test. The language test required participants to match the predetermined Setswana definitions with hypothetical Setswana nouns with selected class prefixes attached to them. The results from the empirical study showed that speakers were associating prefixes to certain semantic values, suggesting that each noun class had specific semantic content that was unique to that class. The semantic categories created through the dictionary analysis were then compared to those given by the thirty-nine Setswana speakers, to analyse whether there were any similaritires in the semantic classification of the noun classes. The findings of the dictionary analysis and linguistic test revealed that there were certain semantic characteristics that each class was associated with that seemed to be unique to the class. However, there were various semantic overlaps in the semantic categories associated with the different noun classes, which brings into question whether a semantic classification is viable in the classing of nouns. The study suggests that prior classification of Setswana nouns are not precise enough and that additional semantic categories are needed to offer a more precise classification of nouns in this language.

- Description: Interactions between insects have been shown to be important regulators of population abundances and dynamics as well as drivers of spatial segregation and distribution. These are important aspects of the ecology of insects used in biological control and may have implications for the overall success of a particular programme. In the history of biological control there has been a tendency to release a suite of agents against a weed, which in some cases has increased the level of success, while in others little change has been observed. In most of these cases the implications of increasing the level of complexity of the system is not taken into account and there is little research on the effect of releasing another agent into the system. A brief meta-analysis was done on all the biological control programmes initiated in South Africa. Emphasis was placed on multi-species releases and the effects that overlapping niches were having on the number of agents responsible for the success of a programme. Where overlapping niches were present among agents released the number of agents responsible for success was lower than the number established. Water hyacinth, Eichhornia crassipes (Martius) Solms-Laubach in South Africa has more arthropod agents released against it than anywhere else in the world, yet control has been variable. If the biology and host utilisation of all the agents against water hyacinth is considered, a definite overlap of niches is apparent in at least one life stage of all the agents. Therefore the probability of these insects interacting is high, especially if they are established at the same site in the field. Three of the insects released in South Africa have been selected to investigate possible interactions. They are Neochetina eichhorniae Warner, Neochetina bruchi Hustache and Eccritotarsus catarinensis (Carvalho). Y-tube olfactometer bioassays were used to measure responses of these insects to water hyacinth with prior feeding damage by either conspecifics or heterospecifics. This was done to determine whether olfactory cues played a role in host acceptability and avoidance of conspecifics or heterospecifics. The insects were given a choice between damaged and undamaged plants in various combinations. There was a significant preference for the undamaged plants when given a choice between undamaged and damaged plants. However when the insects were given a choice between two damaged plants there was no discrimination between heterospecific or conspecific damaged plants. This may indicate that there is little or no ecological cost for the insect to share a plant with other insects utilising a similar resource. Insect – insect interactions were investigated in a common garden plot experiment to measure the impact that pairwise combinations of the insect may have on their performance. There was a significant interaction between the mirid E. catarinensis and the weevil N. eichhorniae, with the weevil not performing as well when in combination with the mirid than when alone. Interestingly there was a negative interaction between the two weevil species when in combination, however it was impossible to determine which species was being affected if not both. None of the insects performed significantly better when in combination with another insect. A field study on Wriggleswade Dam in the Eastern Cape, South Africa was initiated to determine whether the relationship between the mirid E. catarinensis and the weevil N. eichhorniae could be determined in the field. The performance of the insects at the different sites in the field suggests that there was an interaction between the agents. This interaction did not limit the establishment of either insect at a site, but it did result in one insect dominating at a site over another. Interactions between the three species of insect tested in this thesis suggest that there are both negative and neutral relationships between them. A basic comparison between the insect performances from 15 sites around the country was done to determine if the spatial segregation observed in the field could be extrapolated to the natural South African situation. The interaction observed between N. eichhorniae and E. catarinensis does seem to extrapolate to the general South African situation where there is definite spatial segregation on a landscape level. The co–occurrence of the two Neochetina weevils at these sites suggests that the negative relationship observed between them in the common garden experiment does not extrapolate to the field. The results from this thesis suggest that the interactions between the agents tested would not limit establishment or have significant ramifications on performance. However, there may be spatial and temporal segregation of these species in the introduced range.

- Description: During the reign of Queen Victoria was seen the gradual emergence of the emancipated woman. The idea that women were innocent beings who must be kept from real knowledge of the world died hard, however, and to the end of the era there were many who repudiated the very concept of emancipation whether in literature or life. Coupled with the chivalrous, idealistic concept of womanhood was Victorian respectability, and it is not surprising that in the earlier Victorian novels we see clearly the idealistic concept of women and the effects of the cult of respectability. To illustrate my theme, of the gradual change in the concept of the novel which naturally kept pace, more or less, with the progress the emancipation of women was making, I have chosen one novel from each of seven great Victorian novelists whose works span the whale era. The only exception I have made is with Charlotte Bronte. In her case the heroines of two of her novels are discussed mainly because she is the first Victorian novelist to sound a note of protest against the then conventional concept of the heroine.

An insight into magma supply to the Karoo Igneous Province a geochemical investigation of Karoo dykes adjacent to the Northwestern sector of the Lesotho volcanic remnant

- Description: The emplacement of continental flood basalt provinces is often ascribed to fissure eruption. However, in many provinces the locations of actual vent complexes remains illusive. In southern Africa, the Karoo continental flood basalt province was erupted during the Jurassic between 183 and 179 Ma. The southernmost outcrop of the Karoo continental flood basalt lavas is the Lesotho remnant; and is comprised of the Drakensberg Group which forms the uppermost portion of the Karoo Supergroup. The geochemical stratigraphy for the Drakensberg Group is well established. At the base, there are a number of small volume compositionally diverse units, which form the Barkly East Formation, overlying which, there are larger volume, compositionally less variable units of the Lesotho Formation, which form the bulk of the volcanic sequence. The Lesotho remnant is associated with an abundance of dykes in the adjacent vicinity. This suggests that the lavas were fed from local rather than distal eruption sites. This study presents whole rock major and trace element data for 94 dykes and three sills from the northern Lesotho - northeastern Free State region and demonstrates that on the basis of geochemistry, all 97 intrusions can be correlated with various units of the northern Barkly East and Lesotho Formations. In addition, the petrographical; characteristics, orientation and distribution of the dykes do not correlate with geochemistry. Geochemical discrimination diagrams have been used to identify five compositionally diverse dykes, which are similar to the northern Barkly East Formation units. Three dykes are characteristic of the Letele unit and two are compositionally similar to the Wonderkop unit. Although the geochemical characteristics of the Lesotho Formation units are rather well constrained, the composition of these units is typified by considerable overlap in composition. Therefore, since unambiguous classification of dykes with geochemical similarities to the various units of the Lesotho Formation is unachievable using an empirical approach, the multivariate forward-stepwise discriminant function analysis (DFA) technique was used to facilitate the classification of the remaining 89 dykes and three sills. Forward-stepwise DFA classified 23 dykes as having compositional similarities to the Mafika Lisiu unit, 29 as having compositions of the Maloti or Senqu types; and 32 as having the composition of the Mothae type. In addition, eight dykes are compositionally similar to the Oxbow dykes, which intrude the Senqu unit in northern Lesotho. These results suggest that that the Lesotho remnant was fed from local eruption sites and that long distance magma transport for the bulk of the Lesotho remnant basalt lavas is unlikely.

- Description: The aim of this study is to analyse selected episodes of the locally produced television programme Generations, in order to identify specific ways in which the programme seeks to forge a South African identity, and in so doing, 'flag' our nationhood as South Africans. These elements of 'South Africanness' are broadly defined as connections to a South African way of life, context, values and experiences. Generations is a programme produced under South African broadcasting local content provisions. These provisions arise out of the need, inter alia, to reflect the identity and multi-cultural nature of South Africa in order to foster 'national identity' and 'national culture'. These elements of 'South Africanness' are extracted through a genre and ideological analysis of selected sample episodes, taking into consideration the theoretical frameworks of the politics of representation and identity. The production context of, and representations made, in Generations, are found to be situated largely within the context of the South African discourses of the ‘rainbow nation', 'African renaissance' and 'black economic empowerment'. The analysis concludes that through the various categories of representations of 'South Africanness' in the selected episodes of Generations, specific instances of identity, that of national culture and national identity are formed.

- Description: Evidence suggests that the prevalence of certain non-communicable diseases, such as hypertension, is increasing rapidly, and that patients with these diseases are making significant demands on the health services of the nations in sub-Saharan Africa. However, these countries also face other health-related challenges such as communicable diseases and underdevelopmentrelated diseases. Developing countries like South Africa have limited resources, in terms of man power and financial capital, to address the challenges that they are facing. Non-communicable diseases cannot be ignored and since health care providers cannot meet the challenges, it is worthwhile to empower patients to be involved in the management of their conditions. Patient education is a tool that can be used to enable patients to manage their chronic conditions and thereby reduce the morbidity and mortality rates of these conditions. The aim of this study was to investigate the effect of a patient education intervention on participants’ levels of knowledge about hypertension and its therapy, beliefs about medicines and adherence to anti-hypertensive therapy. The intervention consisted of talks and discussions with all the participants as one group and as individuals. There was also written information given to the participants. Their levels of knowledge about hypertension and its therapy were measured using one-on-one interviews and self-administered questionnaires. Beliefs about medicines were measured using the Beliefs about Medicines Questionnaire (BMQ) whilst adherence levels were measured using pill counts, elf-reports and prescription refill records. The participants’ blood pressure readings and body mass indices were also recorded throughout the study. The parameters before and after the educational intervention were compared using statistical analyses. The participants’ levels of knowledge about hypertension and its therapy significantly increased whilst their beliefs about medicines were positively modified after the educational intervention. There were also increases, though not statistically significant, in the participants’ levels of adherence to anti-hypertensive therapy. Unexpectedly, the blood pressure readings and body mass indices increased significantly. The participants gave positive feedback regarding the educational intervention and indicated a desire for similar programmes to be run continuously. They also suggested that such programmes be implemented for other common chronic conditions such as asthma and diabetes. This study proved that patient education programmes can be implemented to modify patients’ levels of knowledge about their conditions and the therapy, beliefs about medicines and adherence to therapy. However, such programmes need to be conducted over a long period of time since changes involving behaviour take a long time.

- Description: Written in fragments and combining fiction and narrative non-fiction, this novella explores how South Africa's history of violence and current violence against women affects and influences how women relate to each other. Based in the knowledge that our memories and behaviours are linked to the experiences of our ancestors via our bodies, I engage what our violent history and the disappearing myths that are still embedded in our bloodstream mean for life today. Drawing on the experiences of several generations of women in my family, current affairs and the lives of women close to me, my novella picks at the fragile things that hold us together. I take influence from the prose poetry in Claudia Rankine’s Citizen, and the use of fragmentation, myth and biography in Lydia Yuknavitch’s A Chronology of Water and Lily Hoang’s A Bestiary, and use an amalgam of genres to ask how we hold each other; how we breath, create, love and dream.

- Description: Written in fragments and combining fiction and narrative non-fiction, this novella explores how South Africa's history of violence and current violence against women affects and influences how women relate to each other. Based in the knowledge that our memories and behaviours are linked to the experiences of our ancestors via our bodies, I engage what our violent history and the disappearing myths that are still embedded in our bloodstream mean for life today. Drawing on the experiences of several generations of women in my family, current affairs and the lives of women close to me, my novella picks at the fragile things that hold us together. I take influence from the prose poetry in Claudia Rankine’s Citizen, and the use of fragmentation, myth and biography in Lydia Yuknavitch’s A Chronology of Water and Lily Hoang’s A Bestiary, and use an amalgam of genres to ask how we hold each other; how we breath, create, love and dream.

- Description: The purpose of this study was to investigate whether the space provided by a readerresponse transaction between girls and the text, Roll of Thunder, Hear My Cry (Taylor 1977) .. empowered pupils to tell their own stories. It also sought to identify ways in which the problems and possibilities perceived by these pupils might guide curriculum decisions in a transforming education system. In addition to engaging in reader-response activities around the text, drama and videos providing social context were integral to the programme. Related work in the subject areas of history and lifeskills was also undertaken. Data was drawn from pupils' reading journals, responses to specific passages, transcripts of small group discussions, and interviews. The study is ethnographic in nature and all the data qualitative. Theoretical insights were drawn from the felds of cultural studies, postmodern criticism, and postructural modes of cultural and social analysis inasfar as they illuminate and inform the relationship between language, knowledge and power. The research was conducted in an historically white, girls' school which adopted a nonracial admissions policy in January 1991. Despite the fact that existing traditions and values of the the school to a very large extent influence what is taught, the data suggests that pupils were becoming agents in their own learning and were taking up multiple identities both within and without the world of the school.

- Description: It was hypothesised that there would be behavioural consistencies in the offences of South African serial killers. The themes underlying these observable differences can help us understand the nature of these offences. Crime scene data was ohtained from police records, and structured, in-depth offender interviews. 73 offences, committed by 13 offenders, were analysed. The analysis used Smallest Space Analysis (SSA), a Multidimensional scaling (MDS) procedure. This analysis revealed systematic patterns of behaviour in the offences. It was found that the focus of these offences is an impersonal, hostile, and act-focused murder were the victim is treated as a depersonalised object. Empirical support for an underlying thematic structure to these offences was also provided. The offence themes identified relate to the nature of the actions committed during the offence, and the function these actions had for the offender. These fmdings thus support the hypothesis that these offences will display meaningful behavioural variation. These findings have direct utility in the investigation and study of serial killing in South Aflica. They also provide the basis for comparison with previously suggested typologies of serial killing, and indicate directions for future research into this phenomenon in the South African setting. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Human-wildlife conflict frequently involves carnivores, mainly because of their large home ranges and dietary requirements. As such, carnivores tend to be the first animals to be lost in human-dominated ecosystems. This is significant because the removal of carnivores can alter the functionality of ecosystems. However, the conservation of carnivores depends as much on the socio-political and socio-economic landscapes as it does on the ecological one. The consolidation of vast, un-fragmented conservation areas in Africa and the world is unlikely. Thus, unravelling the factors (both biological and sociological) responsible for and influencing human-predator conflict is critical for carnivore conservation. The Winterberg district in the Eastern Cape, South Africa has been a sheep (Ovis aries) farming stronghold for nearly 200 years. Consequently, conflict between farmers and predators is commonplace and depredation of livestock by caracals (Caracai caracal) remains a perennial problem. However, the extent of this human-predator conflict (including a reliable assessment of caracal density) has not been quantified. This study used camera trapping to estimate the density of caracals (a nonindividually recognisable species) in the Winterberg and a structured questionnaire to gauge the general attitudes of the farmers of the region. Caracal density was estimated to be 0.20 caracals/km². This estimate equates to a population of approximately 54 caracals across the entire district. Therefore, caracals do not appear to occur at high densities in the Winterberg. However, the survey of the residents of the Winterberg Conservancy revealed that predators were rated as the greatest problem faced by farmers in the area. Although not significant, it also showed that the size of a respondent's property and sheep mortality due to caracals had the greatest probability of affecting attitudes towards predators. The farmers lost less than 10% of their stock to caracal depredation on an annual basis. Therefore, the general perception that predators were the most important factor in stock loss in the area does not appear to be fully supported by my data. The Winterberg is a male-dominated, multigenerational society and it is likely this propagates certain perceptions towards predators which are a reflection of long-held family traditions and beliefs. Such situations can result in reactions which are disproportionate to the actual scale of the problem. However, my study was limited to a sub-set of the landowners in the Winterberg. Thus, more intensive assessments of caracal space use and community attitudes towards predators are recommended.

- Description: The aim of this qualitative study is to explore the perspectives of current members of the cooperative regarding the role of social capital in the success of the Heiveld Cooperative on the Suid Bokkeveld in the Northern Cape, South Africa (SA). This cooperative has been cited by several researchers as being successful for various reasons, including the existence of a marketable resource, a steady increase in production, and certification through Fairtrade, resulting in an export market. Social capital, as a contributing factor to the success of the cooperative, has not however previously been investigated in depth. In light of the unique success of this cooperative, it is important to obtain an in-depth understanding of the role of social capital, if any, in its success, particularly in the formation and day-to-day operation of the cooperative. With a particular focus on the members’ perspectives of the cooperative, this qualitative research adopted a case study approach to explore and to gain multiple and subjective understanding of the role played by social capital in the success of the Heiveld Cooperative. This may assist the organisation under study, as well as similar initiatives, in strategically harnessing the benefits of social capital as a resource in future. This report has three interrelated sections. The first part is an academic paper, which includes a condensed literature review, research methods, results and discussions. The second part is an expanded literature review, while the third section details the research methods. It is vital to note that these sections are separate, but interrelated. Convenience sampling was used to identify current members of the cooperative who participated in this exploratory qualitative study. Four heterogeneous focus group discussions, with a total of 44 members of the Heiveld Cooperative in the Suid Bokkeveld, were conducted. The focus groups were heterogeneous, as they included ordinary members, founding members and committee members. A guideline with questions based on the theory of social capital was developed, and used to initiate or stimulate discussion among the members of the cooperative in order to address the key research question, namely: What was the role of social capital, if any, in the success of the Heiveld Cooperative in the Northern Cape as perceived by current cooperative members? The primary source of data was collected through focus group discussions, while secondary data was obtained from documents in a form of internal reports and papers written for the Heiveld Cooperative. Data was analysed using open coding and constant comparison techniques in order to induce emerging themes from the data. Findings of this study revealed that social capital played a major and influential role during the inception and also in the successful operation of the Heiveld Cooperative, by bonding and bridging not just between individual members, but also between communities, trading partners and other collaborators. Another key finding of this study is that social capital was also critical in enhancing supportive knowledge sharing, and the promotion of pride and shared identity, which the study identifies as aspects of cognitive social capital. Interestingly, the cognitive dimension of social capital in the Heiveld Cooperative has contributed to the weakening of social capital, as evident in claims related to lack of transparency and procedural injustice. Last, but not least, leveraging the sense of community has also been useful in promoting collective efficacy, strengthening familial togetherness, and enhanced democratisation of decision-making. Diminished trust, based on perceived oligarchy and nepotism is gradually weakening relational social capital. Findings in this study are illuminated using the social capital theory described by Nahapiet and Ghoshal (1998) to depict the social, cognitive and relational aspect of social capital that are at work at Heiveld Cooperative. Additionally, the social network theory by Hoppe and Reinelt (2010) is used to highlight the systemic view of social capital, which embraces the structural, relational and cognitive nature not only internal to but also between networks of the cooperative. Recommendations are provided to ensure social capital is harnessed, rather than undermined. These include the need to promote the processes of learning, monitoring and discussion that have been implemented; harnessing the benefits of bonding and bridging social capital; leveraging the sense of community and applying a more systemic view of social capital; and addressing perverse aspects of social capital such as nepotism and oligarchy that have been identified.

- Description: The rapidly growing interest in the potential use of topical drug delivery formulations has resulted in increased use of the skin as a vital port for drug delivery. Extensive research has been conducted in designing vehicles capable of delivering a desired amount of drug to a specific site, to produce the desired pharmacological response. Rooperol tetra-acetate is a lipophilic, cytotoxic drug with the potential for use in the treatment of solar keratosis. For effective pharmacological action, delivery of the drug to the epidermal/dermal junction of the skin is required. A study of the topical penetration properties of rooperol tetra-acetate from different topical bases, each possessing different physico-chemical properties, was performed. The assessment involved a comparison of the diffusion properties under occlusive and non occlusive conditions when the drug was formulated into a gel, Cetomacrogol Cream B.P. (oil-inwater), Simple Ointment B.P. and an extemporaneously prepared water-in-oil topical cream. The in vitro experiments were conducted using polydimethylsiloxane and rat membrane mounted in a Franz diffusion cell. The topical permeation kinetics of rooperol tetra-acetate were determined by exploring the release characteristics of the active ingredient from the vehicles formulated and the permeability properties of the drug through the membranes employed. Further studies involved investigating the utilization of supersaturated systems intended to increase the thermodynamic activity of the drug when formulated into a propylene glycol/water vehicle (with and without polymer). To measure the release of rooperol tetra-acetate into the skin from a topical base it was necessary to, firstly, develop a suitable quantitative method for the analysis of the active drug in the aqueous receptor phase of in vitro diffusion cells. The second stage of product development was the design of an effective delivery system to facilitate the release of the diffusant from its base. A high performance liquid chromatographic method was utilized for the identification and quantification of the active drug. As validation is an important aspect in the development and subsequent utilization of an analytical procedure, the developed HPLC technique was validated by determining the precision, accuracy, range, limit of quantitation and sensitivity of the system. Lastly, the stability of rooperol tetra-acetate at elevated temperatures was assessed and a stability profile of the drug was generated for the three-month period of analysis. The results obtained following chromatographic analysis of the receptor phase sampled during the diffusion experiments indicate that the gel and oil-in-water formulations most effectively promoted the diffusion of rooperol tetra-acetate across polydimethylsiloxane membrane. The water-in-oil system exhibited lower flux rates and the ointment showed the least drug release. Occlusion of the topical vehicle increased the diffusitivity of the permeant from all formulations analysed. The permeation assessment results of the supersaturated systems showed enhanced diffusion of rooperol tetra-acetate across polydimethylsiloxane and rat membrane. The high thermodynamic activity existing in supersaturated systems most effectively increased the driving force for drug diffusion resulting in enhanced percutaneous penetration of rooperol tetra-acetate beyond the release and transport limitations of saturated solutions. These results provide the basis on which an effective topical drug delivery vehicle may be designed for this new drug entity.

- Description: J.J.R. Jolobe is regarded as one of the individuals who made a valuable contribution to the development of isiXhosa literature through his works, notably in his poetry (Ilitha, Umyezo; Jolobe 1936). His poetry ranges from abstract subjects to more philosophical matters. This study is aimed at decoding the manner in which he employs satire to conscientise African people of the then horrible situation that they were facing. With that said, poetry will not be the only work that this thesis analyses in the process of evaluating Jolobe’s satire; his essays will also be examined (Amavo; Jolobe 1940). Based on the writings of various authors specialising in the subject, satire has been deemed to be a style of literary writing, one which involves invective satire. For the researcher, that statement will be rebutted, as it will be argued that the mode of satire need not be wholly invective. Jolobe’s light-hearted satire not only showcases the amusing side of his writings, but also indicates the seriousness with which they were intended. Themes covered in Jolobe’s satire have inspired the researcher to evaluate these literary texts in relation to modern contexts, especially when it comes to the relationship between the lines of the author’s experience and the public. With that said, the social role of satire is something that one cannot deny. One could therefore say that there is an urgent need for African satirists to face the existing social and economic reality as authentically as possible. The voice of a satirist should also echo the voice of their society as a whole. Satirical study in post-colonial Africa, in South Africa in particular, is useful due to the idea that the works of the likes of Jolobe may diminish in significance due to neo-colonialism. In fact, this is the point which is considered in this study of Jolobe’s satire. This study also examines stages afforded to the development of satire in Africa, especially in the post-colonial era. The purpose is to identify the effects of satire that are related to socio-political as well as religious factors. These factors are often seen as those that play a vital role is one’s personal morals, and those that are meant to shape the whole community. Jolobe addresses imperialism and the class struggle, which speaks to the society’s loyalties regarding the mobilization toward realizing the dream of being independent. This speaks to the works analysed, revealing protests against oppression and exploitation by imperialists; such works show how inhumane people could be against those who they deem to be beneath their standards. Researchers like Mahlasela (1973), Sirayi (1985), Kwetana (2000) and Khumalo (2015) are amongst those who have made it a point to study Jolobe to ensure that these works are kept alive, along with their significance. Other prospective researchers can follow suite in researching the great Jolobe. In ensuring that the aims of this study come to light, the researcher will be using socialist realism as a way of seeing that the works of Jolobe are realistic in nature.

- Description: J.J.R. Jolobe is regarded as one of the individuals who made a valuable contribution to the development of isiXhosa literature through his works, notably in his poetry (Ilitha, Umyezo; Jolobe 1936). His poetry ranges from abstract subjects to more philosophical matters. This study is aimed at decoding the manner in which he employs satire to conscientise African people of the then horrible situation that they were facing. With that said, poetry will not be the only work that this thesis analyses in the process of evaluating Jolobe’s satire; his essays will also be examined (Amavo; Jolobe 1940). Based on the writings of various authors specialising in the subject, satire has been deemed to be a style of literary writing, one which involves invective satire. For the researcher, that statement will be rebutted, as it will be argued that the mode of satire need not be wholly invective. Jolobe’s light-hearted satire not only showcases the amusing side of his writings, but also indicates the seriousness with which they were intended. Themes covered in Jolobe’s satire have inspired the researcher to evaluate these literary texts in relation to modern contexts, especially when it comes to the relationship between the lines of the author’s experience and the public. With that said, the social role of satire is something that one cannot deny. One could therefore say that there is an urgent need for African satirists to face the existing social and economic reality as authentically as possible. The voice of a satirist should also echo the voice of their society as a whole. Satirical study in post-colonial Africa, in South Africa in particular, is useful due to the idea that the works of the likes of Jolobe may diminish in significance due to neo-colonialism. In fact, this is the point which is considered in this study of Jolobe’s satire. This study also examines stages afforded to the development of satire in Africa, especially in the post-colonial era. The purpose is to identify the effects of satire that are related to socio-political as well as religious factors. These factors are often seen as those that play a vital role is one’s personal morals, and those that are meant to shape the whole community. Jolobe addresses imperialism and the class struggle, which speaks to the society’s loyalties regarding the mobilization toward realizing the dream of being independent. This speaks to the works analysed, revealing protests against oppression and exploitation by imperialists; such works show how inhumane people could be against those who they deem to be beneath their standards. Researchers like Mahlasela (1973), Sirayi (1985), Kwetana (2000) and Khumalo (2015) are amongst those who have made it a point to study Jolobe to ensure that these works are kept alive, along with their significance. Other prospective researchers can follow suite in researching the great Jolobe. In ensuring that the aims of this study come to light, the researcher will be using socialist realism as a way of seeing that the works of Jolobe are realistic in nature. With that said, there will be an exploration of allegoric satire. Satiric allegory will be evaluated with regard to the view that it represents a unique slant on satire, whereby it deems satire to be more than just a supportive method of literary criticism. This allows the researcher to hold the view that satire should not be a restrictive framework when dealing with African literature. Satire as a modern form of criticism can be viewed as having an element of humanism, which would result in the satirist doing all he can to make sure that what is satirized is not isolated from the struggle of the community. It is for the above-mentioned reasons that we see a big challenge in the future development of satiric discourse in African literature.
