- Description: Catorhintha schaffneri Brailovsky and Garcia (Hemiptera: Coreidae) is a biological control agent that was recently accepted for release in South Africa to control Pereskia aculeata Miller (Cactaceae), an invasive creeping cactus. The aim of this thesis was to conduct post-release research to ensure that C. schaffneri is utilised to its full potential. To achieve this aim, and focus release efforts, the thermal physiology of C. schaffneri was investigated to predict where in South Africa the agent is most likely to establish. These predictions were then tested by releasing the agent at field sites with a wide variety of climatic conditions and evaluating establishment success. When invasive plants invade a wide distribution, made up of areas with different climatic conditions, biological control agents may not establish or be effective throughout the invaded distribution. According to the thermal physiology of C. schaffneri, it is most likely to establish and become effective in the subtropical region of South Africa, along the coast of KwaZulu- Natal. Cold winters, or generally low year-round temperatures, may limit establishment in the more temperate areas of South Africa in the Eastern and Western Cape as well as inland in the Highveld region. These predictions can be used to focus release efforts to climatically suitable regions and stop releases in areas where C. schaffneri cannot survive. Predictions based on thermal physiology may not account for all of the variables which affect establishment. To account for other variables, the establishment of C. schaffneri was tested using closely monitored field release studies. During these studies the effect of other variables such as; microclimate temperature, humidity, precipitation, plant quality and release strategy were considered. Low humidity, precipitation and plant quality appear to affect the establishment of C. schaffneri in the subtropical areas of South Africa. The experiment was conducted during a period of drought, and this may have resulted in lower establishment rates. The most successful release strategy for C. schaffneri was the use of multiple, small releases rather than single releases of the same number of individuals. The field based study was therefore able to improve the biological control of P. aculeata by increasing the chance that each release of C. schaffneri results in establishment. The post-release studies presented in this thesis will increase the impact of C. schaffneri by focussing release efforts to climatically suitable sites, releasing at appropriate times of year and releasing the agent in a manner that increases establishment success. Post-release studies, such as those presented here, can make biological control programmes more efficient and effective.

Post-release evaluation of the biological control programme against Cereus jamacaru De Candolle (Cactaceae), in South Africa

- Description: Cereus jamacaru De Candolle (Cactaceae) is an environment-transforming weed of both agricultural and wildlife habitats in South Africa. Weed infestations reduce carrying capacity of the land, and pose a risk to livestock, wildlife and human safety due to the plant’s spiny thorns. The weed is considered to be under complete biological control in South Africa, due to its introduced control agent, Hypogeococcus festerianus Lizer y Trelles (Hemiptera: Pseudococcidae), although observational reports suggest that the level of success achieved is variable. In this thesis, a formal post-release evaluation of this biological control programme was conducted, specifically to determine the efficacy of H. festerianus as a biological control agent, and to identify factors which may limit or constrain the level of success achieved by the control agent. These data were collected with the intention of improving the control of C. jamacaru in South Africa. A field-based study of C. jamacaru population demographics investigated the efficacy of H. festerianus as a biological control agent of the weed, by integrating weed growth, fecundity and survival metrics with C. jamacaru population dynamics and demographic patterns from 8 sites where H. festerianus was present and 14 sites where the control agent was absent. The findings indicated that H. festerianus significantly reduced weed fecundity, which resulted in fewer seedling recruits, and that levels of plant mortality were greater at sites where H. festerianus was present. The reduction in weed fecundity and survival translated into negative population-level consequences for H. festerianus. Weed-population age frequency distributions in the absence of H. festerianus demonstrated a “reverse J-shaped” distribution, indicative of high recruitment rates and population stability, while C. jamacaru populations infected with H. festerianus were described by bell-shaped distributions, and were typified by limited recruitment, or a complete lack thereof. By constraining recruitment and inhibiting selfregeneration, H. festerianus appears to regulate populations of C. jamacaru. Predation and parasitism of H. festerianus was believed to be a limiting factor for the biological control programme against C. jamacaru in South Africa, although no formal evaluation of this claim had been undertaken. Accordingly, the assemblage of natural enemies acquired by H. festerianus in South Africa was identified by field-collections of infected H. festerianus gall-material. Further, timed point-count surveys of natural enemies associated with H. festerianus were performed and integrated with the data on the impact of H. festerianus on weed population dynamics to assess the impact of two prominent predaceous taxa on H. festerianus efficacy as a biological control agent. Although H. festerianus had acquired a diverse suite of novel natural enemies in South Africa, this has not prevented the biocontrol agent from having an impact on C. jamacaru populations, although other subtler effects cannot be ruled out. This study showed that biological control efforts employing H. festerianus for the management of C. jamacaru have been successful. Furthermore, these data demonstrated the utility of retrospective analyses in developing and improving the science of biological control, specifically how to improve candidate agent prioritisation, determining how many agents are required for successful biological control, and how to evaluate the success of biological control efforts. Improvements in our theoretical understanding of biological control will undoubtedly reduce costs of biological control programmes, improve success rates, and increase the predictability of biological control.

- Description: The main focus of this thesis is to show the nature of the relationship between the South African Defence Force and the local media from 1975-83. The thesis will analyse issues specifically relating to the nature of the relationship and show how and why they are relevant to understanding the authoritarianism of the apartheid state. The nature of the relationship will be conceptualised by way of the analogy of a marriage. The thesis will show that for the SADF the relationship was “a marriage of convenience” whereas for the media it was a “marriage of necessity”. This relationship operated within the context of a highly militarised society that has been termed a “Garrison State”. The apartheid government introduced legislation governing reporting of defence matters and the media (namely the South African Defence Act 1957 including amendments made up until 1980) that imposed legal constraints within which defence correspondents had to operate. Moreover, the MID’s secret monitoring of the local media reveals the extent to which the military distrusted the media. A sampling of the coverage of defence matters in a selection of newspapers will reveal how their editorial staffs and reporters operated in a situation where the flow of information was controlled by the military. This will also show that certain defence correspondents cultivated close relations with SADF personnel to ensure that they were kept informed. The thesis will also show how the SADF reacted to the international media exposure of Operation Savannah and Operation Reindeer and how the SADF sought to limit the damage to its reputation by clamping down on the local media. The creation of two media commissions both headed by Justice MT Steyn, set out to investigate the manner in which local media reported on security issues in an environment in which the media and the public were confronted by the “Total Strategy” discourse of the apartheid government. The working relationship between the SADF and the media encapsulated in the thesis can be described as highly complex and the use of the “marriage” analogy assists in understanding this relationship.

How do editors' attitudes and their perceptions of readers' interests combine with other factors to influence the publication of articles on the natural sciences in the Daily Dispatch?

- Description: This half-thesis examines how editorial values and perceptions determine the quantity and nature of science articles published in the Daily Dispatch, a newspaper distributed through large parts of the Eastern Cape in South Africa. It was predicated on the notion that South African media in general does not cover the natural sciences adequately. In order to test this assumption I decided to investigate the production and publication of science content at the Daily Dispatch as a test case. This study‘s theoretical framework draws on the normative roles of the media in a democracy developed by Christians et al. (2009) and the models of science journalism described by Secko et al. (2012) to demonstrate how two parallel conceptions of democracy set diverse journalistic objectives and engender different types of science content. Having applied an essentially political framework, this thesis uses the Hierarchy of Influences Model devised by Reese and Shoemaker‘s (2014) to explore how an array of forces acting inside and outside the news organisation can shape the publication of science articles. A quantitative content analysis is used to ascertain the number of science articles published in the first six months of 2014. It investigates which science fields received the most coverage, and how prominently the articles are positioned. As the Daily Dispatch does not have any staff dedicated to the science beat, the analysis finds out who produces the science articles that are published. The second phase of this research is a series of interviews with senior editorial staff members aimed at probing the editorial thought processes that determine when and whether specific science stories should be covered. The personal views and biases of the editorial leadership are pivotal to this research because although the newspaper commissioned surveys to determine readership preferences, there were no questions about the sciences. Senior reporters were adamant that they worked for a political newspaper and that as a significant proportion of their readership lived in socio-economically deprived circumstances, they were bound to give priority to articles aimed at improving the lot of their readers. The third phase is a qualitative content analysis of selected articles designed to reveal how science articles are constructed. The final element of this thesis, which ultimately provides an answer to the research question, draws together conclusions from the previous phases to demonstrate the linkage between editorial values and the production of science content.

- Description: South African history is rooted in racial identities, inequalities and injustices, which the post-apartheid government has sought to address for twenty years since 1994. The transition to a post-apartheid society though has been a difficult one with the social structure and everyday life still marked by the racial past. Though racial classifications on an official basis no longer exist, racial identities continue to pervade the country. Of particular significance to this thesis are black identities including the possibility of black inferiority, which I examine in relation to black post-graduate university students in contemporary South Africa, specifically at Rhodes University. In examining this topic, I draw extensively on the work of Frantz Fanon, who wrote about both colonial society and the emerging post-colonial experience. Fanon was a young black intellectual whose work was in part based on his own experiences of being a once-colonised black person in a world which he perceived as being dominated by whiteness. In his work he expresses his own perceptions of whiteness and how the black identity has come to be shaped by and around this dominant white foundation. Fanon extensively discussed the lives of black intellectuals and elites, and demonstrated how the black identity becomes shaped by and around the world of whiteness. In doing so, he raised a range of themes, such as black inferiority, mimicry and double consciousness. I draw upon the work of Fanon in a critically sympathetic manner to delve into the experiences of black postgraduate students as they negotiate their way through a university setting dominated by a white institutional culture. I bring to the fore the argument that the racial identities of these students is not fixed and sutured but, rather, is marked by considerable fluidity and ambiguity such that black identity must be understood not just as a state of being but also as a process of becoming.

- Description: It is well documented that Information and Communication Technologies (ICTs) play an important role in education and that their use is associated with improving student learning and adding value to the curriculum. However, despite the opportunities that ICTs offer, numerous schools in South Africa face various barriers that result in the limited use of ICTs in the classroom. Literature has highlighted the lack of integration as one of these barriers. Teachers focus on teaching about ICTs where the focus is on developing computer literacy or technical knowledge rather than allowing students to learn through or with ICTs. This thesis aims to explore the concept of ICT integration in rural schools, where ICTs form an integral part of teaching and learning practices. It presents a number of theoretical considerations for ICT integration with a particular focus on teacher pedagogical beliefs and barriers to integration. Using interpretivism as the underlying philosophy and thematic analysis as the analysis tool, the author reflects on ICT integration in the ICT4RED project at Arthur Mfebe Senior Secondary School in the Eastern Cape Province. Furthermore, this thesis offers an in-depth understanding of integration barriers in rural marginalised schools. These barriers are presented in Thematic Maps as well as a framework which incorporates both theoretical considerations and themes that emerged from fieldwork.

- Description: The primary purpose of this study was to capture Natural Science teachers’ perceptions of the national standardised achievement tests (SATs), with a view to illuminating whether or not they were able to interpret and use the SATs reports to inform their practice and for improvement purposes as envisaged in the standardised tests’ objectives. It further sought to investigate how the grade 7 Natural Science teachers were teaching the subject matter, with a view to understanding the performance of learners as illustrated in the 2010 SATs results. The study mainly used qualitative methods such as observations, interviews and document analysis. These were complemented by quantitative methods through the use of the questionnaires, which were used to capture the general perceptions and experiences of Natural Science teachers. Thirty-five questionnaires were sent out and ten responses were received. Quantitative data from the questionnaires were analysed by tabulation to ascertain the frequencies of responses regarding teachers’ perceptions and experiences of SATs, as indicated in different scales per indicator. Furthermore, data generated through video-taped lessons, analysis of learners’ written notes, interviews and open-ended questions from the questionnaires were inductively analyzed. The findings of the study revealed that teachers had positive perceptions towards the ideals of SATs. However, their use of the SATs reports in their teaching was inconclusive. The study also revealed that there were no policy imperatives on SATs, in particular, to guide their use in schools. It was also found that teachers were not teaching the syllabus competencies fully and their Natural Science content knowledge was inadequate. The principal recommendation is that teachers need to acquaint themselves sufficiently with the SATs reports to enable them to use the reports for their intended purposes. Furthermore, teachers need to engage in continuous professional development programmes to improve their Natural Science content knowledge, especially with regard to making information in the textbooks accessible to learners in terms of addressing competencies in the syllabus. Finally, there is a need for policy intervention from the Ministry of Education in Namibia so that the existing tensions between policy formulation and implementation are addressed.

The principal recommendation is that teachers need to acquaint themselves sufficiently with the SATs reports to enable them to use the reports for their intended purposes. Furthermore, teachers need to engage in continuous professional development programmes to improve their Natural Science content knowledge, especially with regard to making information in the textbooks accessible to learners in terms of addressing competencies in the syllabus. Finally, there is a need for policy intervention from the Ministry of Education in Namibia so that the existing tensions between policy formulation and implementation are addressed.

- Description: The cheetah (Acinonyx jubatus) has experienced a drastic decline in numbers over the last 20 years globally and is currently listed as vulnerable by the International Union for the Conservation of Nature (IUCN). In South Africa, there are only an estimated 763 free-ranging cheetahs and conflict with humans is arguably the most significant reason for this low number. The aim of my study was to determine the population size and demographic characteristics of the cheetah population within the Timbavati Private Nature Reserve (TPNR), South Africa, and to contribute to a better understanding of cheetah space use and habitat selection. The research was conducted on TPNR between November 2009 and June 2011 and I used a photographic survey to assess cheetah population size and demographic characteristics. Location data was obtained by collaring two adult male cheetahs with GPS/GSM collars and ad hoc sightings data from across the reserve for an adult female with cubs and three adolescent females. A relatively high minimum population density of 4.46 cheetahs/100km² was estimated, signifying a relatively healthy cheetah population. The sex ratio data indicated a higher male to female ratio and an average litter size of three cubs. The relatively high cub survival rate and density is promising in terms of the status of species within the area, as the data denote the success and potential persistence of the species. Cheetah home ranges varied between 20.97km² for the female with cubs and 659.65km² for the younger collared male. Season did not appear to be a determining factor in terms of home range sizes for the three social groups within the TPNR. However, the males did show a slight increase in their home range sizes during the dry season when resources where presumably more widespread. My results indicate that the cheetah is an adaptable species, flexible in behaviour and able to tolerate a variety of habitat types. Such knowledge is fundamental for planning and implementing the effective management and conservation of cheetahs in South Africa.

- Description: The successful launch of the European Monetary Union (EMU) raised an already ever growing interest in the economics of monetary integration and the formation of monetary unions around the world. Following the EMU experience, countries have considered forming a monetary union amongst themselves. The East African Community (EAC), comprising the three original member countries Kenya, Tanzania and Uganda and now including Burundi and Rwanda, is an example of such a group of countries that seek to form a monetary union. This study aims to identify the current level of financial integration amongst the East African countries. In order to do so the study examines whether the pass-through of monetary policy in the five countries has become similar over time. This is to provide an indication of the extent to which the nominal convergence criteria amongst the member countries have been met. The results of the study provide an indication of whether the formation of a monetary union in East Africa is possible. The empirical analysis used in this study included stationarity tests, four tests of co integration and an asymmetric error correction model to investigate whether the pass-through of monetary policy transmission in the five countries has become more similar over the ten year sample period from 1999 to 2008. The analysis uses three interest rates and 6-year rolling windows to identify the extent of macroeconomic convergence that prevails within the EAC, and consequently whether the formation of a monetary union is possible. The results suggest that the magnitude of the convergence amongst the countries remain low and there are significant rigidities in the deposit and lending rates over time, however the passthrough has improved with respect to the lending rate but not the deposit rate. The overall conclusion of the study suggests that an EAC wide monetary union is currently not possible based on the evidence provided from the pass-through analysis.

- Description: Looking primarily at the social and political trends in South Africa over the course of the last century and a half, this thesis explores how these trends have contributed to the establishment of the southern Africa cannabis complex. Through an examination of the influence which the colonial paradigm based on Social Darwinian thinking had on the understanding of the cannabis plant in southern Africa, it is argued that cannabis prohibition and apartheid laws rested on the same ideological foundation. This thesis goes on to argue that the dynamics of cannabis production and trade can be understood in terms of the interplay between the two themes of ‘prohibition’ and ‘resistance’. Prohibition is not only understood to refer to cannabis laws, but also to the proscription of inter-racial contact and segregation dictated by the apartheid regime. Resistance, then, refers to both resistance to apartheid and resistance to cannabis laws in this thesis. Including discussions on the hippie movement and development of the world trade, the anti-apartheid movement, the successful implementation of import substitution strategies in Europe and North America from the 1980’s, and South Africa’s incorporation into the global trade, this thesis illustrates how the apartheid system (and its collapse) influenced the region’s cannabis trade.

The purpose of analysing this law is to advise and assist ILAM in fulfilling royalty payment obligations as stipulated in a contract signed between ILAM and the Smithsonian Global Sound (formally Global Sound Network) in 2001. In order to clearly comprehend the scope of the royalty payment clause in the Smithsonian Institution’s contract with ILAM, this research includes an examination of: the history and nature of South African copyright as a sub-structure of intellectual property; specific internationally documented copyright infringement cases; the recording and documentation practices of Hugh Tracey (ILAM’s founder and director from 1954 to 1977); the contract between Global Sound Network and ILAM; and contentious issues surrounding collective ownership and indigenous knowledge. In conclusion, this research suggests equitable solutions to ILAM’s copyright concerns and proposes the Eastern Cape Music Archiving Project (ECMAP) as a practical vehicle to assist the South African Department of Trade and Industry in implementation of the South African Intellectual Property Amendment Bill (2008) if, and when, it is passed.

- Description: Erythromycin (ERY) is a macrolide antibiotic which is used in the treatment of acne vulgaris.Acne is a common skin condition that occurs when the sebaceous glands and hair shafts become infected by the bacteria Propionibacterium acnes. Acne is a chronic condition that may last for years and the severity of the effects of the disease on patients is often undermined especially in third world countries where more emphasis is placed on other more life-threatening diseases. It may cause considerable physical and emotional distress to sufferers along with the possibility of permanent scarring. Although use of topical ERY formulations is not the first line of treatment it has proven to be effective in treating inflammation of skin and skin structures cause by the responsible bacteria. To-date there are a variety of vehicles which are used in preparing topical ERY formulations namely ointment and gel bases, alcoholic solutions and pledgets. All the gel formulations on the market contain hydroxypropyl cellulose, alcohol and water along with the active ingredient(s). However, some gel formulations contain propylene glycol in addition to these excipients an example being Emgel®. Propylene glycol has been shown to affect the penetration of topically applied drugs through the skin suggesting that it would be highly likely that those formulations which contain propylene glycol may release more ERY into the skin following application. With this in mind, two ERY gel formulations were produced which contained different percentages of propylene glycol. According to the FDA guidelines, pharmacokinetic measurements in blood, plasma and/or urine of topical dermatological drug products are not feasible to document bioequivalence since the active ingredient(s) in topical formulations is/are not intended to be absorbed into the systemic circulation and in addition, concentrations in extracutaneous biological tissues would generally not be measurable. This limits determination of bioavailability and assessment of bioequivalence of such products to pharmacodynamic measurements, clinical trials and dermatopharmacokinetic (DPK) measurements such as tape stripping (TS) and microdialysis (MD).TS is a sampling technique which involves sequential removal of layers of the stratum corneum using strips of adhesive tape. This technique has found increasing use in DPK studies for investigation of drug kinetics in the skin following the application of a topical formulation. The technique has also been used as a diagnostic tool in assessing the quality of the stratum corneum in diseased skin. In the current research study, the tape stripping technique was used to investigate the pharmaceutical/biological availability of topical gel formulations containing ERY. MD is another DPK sampling technique which has been used to determine the amount of a topically applied drug that penetrates through the stratum corneum to reach deeper tissues of the skin. The in vivo sampling technique involves the insertion of microdialysis probes beneath the skin surface in the dermal tissue and allows for real-time sampling of the analyte at its target site. Recently in vitro MD has also been successfully used to assess the pharmaceutical availability of a topical corticosteroid, mometesone furoate, from topical formulations. Based on this work, microdialysis was used to determine the pharmaceutical availability of ERY from gel formulations which were developed for use in this research. The results of the pharmaceutical availability of ERY from in vivo tape stripping studies and the in vitro microdialysis studies were compared to establish correlation between the data. Pharmaceutical equivalence and bioequivalence data obtained from the respective studies on the gel formulations were investigated by statistical analysis of the data generated from both the in vitro and in vivo experiments. In summary the objectives of this research were: 1. To develop and validate a high performance liquid chromatography method suitable to analyse ERY concentrations obtained from in vitro microdialysis studies and in vivo tape stripping studies. 2. To prepare two different ERY gel formulations with different percentage content of propylene glycol. 3. To determine the pharmaceutical availability of ERY from two different gel formulations using in vitro microdialysis. 4. To develop and validate a tape stripping technique which could be used to determine percutaneous penetration and bioequivalence of the gel formulations. 5. To compare in vitro microdialysis and in vivo tape stripping data and attempt to establish a correlation between the two different approaches.

- Description: Protein folding, translocation, oligomeric rearrangement and degradation are vital functions to obtain correctly folded proteins in any cell. The constitutive or stress-induced members of each of the heat shock protein (Hsp) families, namely Hsp70 and Hsp40, make up the Hsp70/Hsp40 chaperone system. The Hsp40 J-domain is important for the Hsp70-Hsp40 interaction and hence function. The type-II Hsp40 proteins, Homo sapiens DnaJ 1a (Hsj1a) and Plasmodium falciparum DnaJ 4 (Pfj4), are structurally similar suggesting possible similar roles during malarial infection. This thesis has focussed on identifying whether Hsj1a and Pfj4 are functionally similar in their interaction with potential partner Hsp70 chaperones. Analysis in silico also showed Pfj4 to have a potential chaperone domain, a region resembling a ubiquitin-interacting motif (UIM) corresponding to UIM1 of HsjIa, and another highly conserved region was noted between residues 232-241. The highly conserved regions within the Hsp40 J-domains, and those amino acids therein, are suggested to be responsible for mediating this Hsp70-Hsp40 partner interaction. The thermosensitive dnaJ cbpA Escherichia coli OD259 mutant strain producing type-I Agrobacterium tumefaciens DnaJ (AgtDnaJ) was used as a model heterologous expression system in this study. AgtDnaJ was able to replace the lack of two E coli Hsp40s in vivo, DnaJ and CbpA, whereas AgtDnaJ(H33Q) was unable to. AgtDnaJ-based chimeras containing the swapped J-domains of similar type-II Hsp40 proteins, namely Hsj1Agt and Pfj4Agt, were also able to replace these in E. coli OD259. Conserved J-domain amino acids were identified and were substituted in these chimeras. Of these mutant proteins, Hsj IAgt(L8A), Hsj1Agt(R24A), Hsj1Agt(H31Q), Pfj4Agt(L 11A) and Pfj4Agt(H34Q) were not able to replace the E. coli Hsp40s, whilst Pfj4Agt(Y8A) and Pfj4Agt(R27A) were only able to partially replace them. This shows the leucine of helix I and the histidine of the loop region are key in the in vivo function of both proteins and that the arginine of helix II is key for Hsj1a. The histidine-tagged Hsj1a protein was also successfully purified from the heterologous system. The in vitro stimulated ATPase activity of human Hsp70 by Hsj1a was found to be approximately 14 nmol Pí[subscript]/min/mg, and yet not stimulated by Pfj4, suggesting a possible species-specific interaction is occurring.

- Description: This research is born out of recognition of the challenges Black Economic Empowerment (BEE) in the private sector faces in South Africa, with preferential procurement being one of the components of South Africa's Broad Based Black Economic Empowerment Strategy. Over the past years, South Africa has witnessed the birth of a new economy, one that allows for investment in its people, makes provision for sustainable growth through skills transfer and development, and ensures economic empowerment. The focus of this research is the Preferential Procurement strategy implemented at DaimlerChrysler South Africa (DCSA) as part of its overall Black Economic Empowerment strategy, the perceptions and expectations of how the current BEE preferential procurement strategy should work versus the perceived performance of how it is working. An official definition of Black Economic Empowerment is presented in the study, followed by barriers to growth of BEE suppliers. The aim of defining Black Economic Empowerment is to provide a good reference point against which an organization like DaimlerChrysler can assess the implementation of its preferential procurement programmes. Having discussed the above, there will be a reflection on government scorecard and a brief discussion of the two charters namely, mining and financial services charter. The study also presents the following requirements for a successful BEE corporate strategy: Strategic intent; External Balanced Scorecard; Financial Assistance; Skills development; Communication. A research methodology for conducting this study and data analysis is presented, followed by limitations of the study and recommendations for further research. It is expected that the knowledge gained from this study will help to I. Demonstrate the need to change perceptions and behaviour regarding Black Economic Empowerment. 2. Assist procurement officials to include BEE objectives into their procurement strategy. 3. Identify policy implications and assist in improving DCSA's Black Economic Empowerment Procurement strategy.

Abortion: social implications for nurses conducting termination of pregnancies in East London

- Description: Abortion is a highly controversial subject that has again come into the spotlight in South Africa due to the legalisation of abortion on demand in 1996. The results of various studies conducted since the Choice on Termination of Pregnancy Act 92 of 1996 was implemented, have indicated that abortion providers have met with a great deal of negativism and ostracism. This study focused on the implications of abortion work on nurses' social relationships with family, friends, colleagues and their communities. Recent literature was reviewed on the subject. The researcher however, found little information on this specific aspect of abortion. The study was conducted with abortion nurses from two government designated hospitals in the East London area responsible for abortion services. Thus, results cannot be generalised. This is a qualitative study that aimed at obtaining firsthand information regarding the personal experiences of abortion nurses. A non-probability sampling technique was used viz. criterion sampling. The Interview Guide Approach was used whereby in-depth, semi-structured interviewed were conducted with the guidance of a set of questions in the form of an Interview Schedule. The ten respondents were asked to share their recommendations as to possible measures that could address the challenges mentioned during their interviews. The researcher came to the conclusion that nurses' social relationships and lives are definitely impacted by abortion work. This impact is largely negative as the majority of respondents experience labelling, stigmatization and ostracism from family, friends, and their colleagues. Abortion nurses also experience a lack of social support, ambivalent feelings with regard to abortion, and a range of negative emotions ranging from stress and depression to frustration and anger. A number of repeat abortions are being done and there seems to be a general lack of contraception. The need exists for nurses to go to Value Clarification Workshops and also to get support in terms of compulsory, continuous, counselling. Separate wards should be set up for abortions whilst sex education should be included in school curriculums at both primary and secondary schools. Family planning and facts about the abortion process should also be included in these sex education programmes. Overall. the need exists for family planning initiatives to promote contraception and deter women from using abortion as a means of contraception. As this study reveals, conducting abortions has come at a great cost for the majority of nurses who lack social support and bear the brunt of anti-abortion sentiment expressed by significant others in their lives. The latter being the people who would normally be the one's they would turn to for help, counsel, support and assistance

A case for geography in South African senior primary schools: an analysis and evaluation of current geographical thinking and practice

- Description: Geography faces several challenges in a changing South Africa. These include the challenge to initiate a primary curriculum that helps to provide a foundation for sustainable living in a society that faces serious problems of unemployment, violence, irreparable damage to the environment and the lack of housing, water and basic services for the majority of the population. This thesis attempts to provide a case for geography in the primary school by examining the value of the subject for pupils' development and by reviewing the strengths and weaknesses of an integrated approach in view of the possible introduction of an integrated primary curriculum in South Africa. The second aspect of the study is concerned with a survey of teachers in the Natal Education Department to evaluate the perceived value of geography as a subject and support for geography as a discrete subject. The main thrust of geography in the primary school is to develop concepts, skills, values and attitudes that allow pupils to be more understanding and caring about the local and global environment, about people, communities, species and the natural environment on which we all depend. The results of the survey reveal that teachers support geography as a discrete subject with an intra-curriculum approach. The introduction of an integrated core curriculum in South Africa would prove problematic as teachers are not in favour of an integrated approach across the curriculum. The lack of teacher support in Kenya for an integrated curriculum was one of the main reasons for its failure. Hopefully South Africa will learn from other countries experiences with introducing an integrated curriculum. Teachers value the role of geography in the education of the child and suggest the introduction of environmental and development themes to make the subject more relevant to children's lives. The syllabus analysis revealed that a unified pnmary curriculum is required which is influenced by the needs of society in South Africa. Recommendations are made regarding ideas for a future primary curriculum.

An experiment in literary critical appreciation, using a comparison between three nineteenth-century novels prescribed by the Cape Education Department and a random sample of Mills and Boon popular romance fiction

- Description: The novel as an art form provides writers with the opportunity of exercising their imaginative power to create a 'speaking picture' of life. Whatever form that picture may take, it is vital that it should offer relevance to real life. The literature teacher's earnest intention, therefore, should be to encourage an appreciation of literary novels among adolescent pupils in order to enrich the quality of their living and to sharpen their awareness of the human condition. Teaching adolescents to discern the essential differences between the novel of quality and the novel which exists purely to provide wish-fulfilment and sensual titillation is the aim of this dissertation. Thus a structural analysis of the literary novel is presented, asserting that certain aspects of the novel should be identified and appreciated by the developing reader. Three novels which have recently been prescribed by the Cape Education Department for pupils in standards 9 or 10 are briefly examined in order to test the itensity of their illusion of reality in conjuction with the literary skills of their creators. These novels are Pride and Prejudice (Jane Austen), Wuthering Heights (Emily Brontë) and Tess of the d'Urbervilles (Thomas Hardy). Each has been viewed from a different angle, but each reveals its right to be evaluated as great literature. In order to develop literary appreciation among teenage readers, and to convince them of the delights and insights to be gained, it is proposed that comparison of the 'literary' with the 'unliterary' novel should promote discernment and sound judgement. Popular romance fiction, as published by Mills & Boon, is therefore investigated. These stories enjoy immense popularity, particularly among teenage girls. Far from promoting the illusion that life has been faithfully represented, these novels are shown to reveal a world manipulated to suit both the author and the reader: life as it might have been rather than as it is. A sample of adolescent responses to this type of comparative reading is provided in the last chapter. These responses reveal that the pupils' critical faculties were engaged and literary appreciation was evident

The eucharist in St John's Gospel : an examination of the extent to which it is justifiable to see allusions to the eucharist in St John's Gospel

- Description: This thesis shows that the incarnation of Jesus Christ is an ever present reality for St. John. Christ's abiding presence is known to those who are committed to him because he is their Saviour and Lord. This presence is especially real when his disciples, the believers, the Church gather for worship. In the eucharist, which is an act of worship, the meaning and purpose of the incarnation becomes apparent for St. Paul. By showing that aspects of John's understanding of the incarnation co-incide with the early Church's doctrine of eucharist (as portrayed by St. Paul) the conclusion is reached that we have eucharistic allusions in the gospel of John. Furthermore, John presents Jesus in contrast to the Old Covenant. Jesus supersedes the Old Covenant and establishes the new covenant of love. Just as the Old Covenant was celebrated in the Passover, so the eucharist re-enacts the new covenant. By alluding to the old sacrament, John shows how the eucharist fulfils the true meaning of Passover. After a brief examination of existing methodologies, I present the working hypothesis for this dissertation as outlined above. In a fairly detailed exegesis of Jn 6 (with digressions to other relevant passages in John) which is divided into three sections (In 6:1-21 6:22-48, 6:49-71), I have tried to show that John sees the eucharist as a celebration which emphasises the community of the church, which re-enacts God's great demonstration of love (typified especially in the death of Jesus) and which foreshadows that great heavenly banquet, when, all will be gathered to him. I reach the conclusion therefore that we are justified in finding allusions in the eucharist in the gospel of John.
