  • Description: [From Introduction]. The study involved student teachers and teacher educators providing me with information concerning their perception and understanding of the BETD broad curriculum and needlework and clothing syllabus. The above mentioned are the people who are involved in teacher education thus I found it relevant to have their opinions and understanding of the documents. The contextual analysis has engaged me in exploring a possible area of research specialisation for the two years during the course of studies with Rhodes University; this will serve as an introduction to the particular research to be done through the course of my studies. The focus of this report includes the following: • A critical analysis of (BETD) needlework and clothing syllabus in relation to the BETD broad curriculum; • A socio-historic and economic analysis of the context for which the syllabus has been designed; • An analysis of the learners for whom the syllabus is designed. In this case students provided their autobiography; • An analysis ofthe learning environment in which the syllabus operates; the physical structure and resources. Together with the critical analysis of the curriculum a small scale survey intending to find out the following information from the student teachers and teacher educators was conducted. • The extent to which the broad curriculum differs from the previous teacher education on issues related to democracy, quality, access, cultural bias, racial discrimination and classes (level of economic status); • How the needlework and clothing syllabus addresses the needs of student teachers; • Whether the needlework and clothing syllabus has enough content; • The challenges facing teacher education and how they can be addressed; • Whether the needlework and clothing syllabus is learner-centred; • Whether the syllabus is gender oriented or biased. This evaluation framework provides a foundation for later investigation

  • Description: There are a number of papers in the journal that reflect a trend in environmental education towards deliberating recuperative, relational epistemologies. In their paper addressing the near-schism between those that appear to be antagonistic to post-structuralism and deconstruction, and those that find them generative in their inquiries, Noel Gough and Leigh Price go right to the heart of human inquiry by questioning the most commonly held assumption in the research enterprise – that the social sciences require a different methodology from the natural sciences.Through giving attention to relativist (constructionist) epistemology and a stratified, realist ontology – which assumes a relational account of ontology – they suggest the same basic methodology for both the social and natural sciences, arguing that ‘... society and humans mutually transform/reproduce each other, just as nature and humans mutually transform/reproduce each other’. In doing this, they address over-simplified dialectics between ‘constructionism’ and realism which has shaped much human inquiry (including environmental education research).

  • Description: [From Introduction] Rhodes University has had another successful year in terms of research activities and outputs in what has been an exciting Centenary year and I would like to add my congratulations and thanks to those of the Vice-Chancellor to all staff and postgraduate students for their research efforts in 2004. This report documents the research highlights and outputs in its many forms during 2004. Research which is not disseminated in this manner is wasted and I would like to encourage all staff and students to continue to publish their research in the most appropriate way. I would particularly like to stress the importance of publishing research findings in subsidy earning journals and of converting conference papers into journal articles where possible. Outputs in accredited journals are one of the principle means by which the University earns research subsidy and increasing the subsidy earned in this way will directly benefit internally funded research activities. In terms of journal publications 2004 has been a very good year with the audited but still to be awarded journal units increasing to 202 units from 165 awarded in 2003. I am confident that this is a sustainable trend and it is particularly encouraging in the context of a national trend of declining research outputs. A particularly successful publication was the special edition of the SA Journal of Science which was dedicated to the Rhodes University Centenary. I would like to thank all of those staff and students who submitted articles for publication in this edition and Professor Barker for initiating and co-ordinating this publication. An aspect of research outputs which remains a serious concern is the continued poor recognition by the Department of Education of publications in the form of books, chapters, refereed conference proceedings and patents. Not only are a small fraction of these outputs accepted for subsidy purposes but to date no feedback has been given in terms of which books, chapters, etc have in fact been subsidised or why the majority of submissions are not accepted. The Department of Education has, however, indicated that such feedback will be forthcoming from 2005. A further, and possibly even more problematic, aspect of recognition of research outputs (and NRF rating) is the inability to assess outputs in the Performing and Visual Arts. Attempts have been made to address this issue at a national level but no solution appears to be likely in the near future. A concerted and unified national approach to addressing the issue of recognition of research outputs other than articles in accredited journals is urgently needed at the highest level if the research efforts in many disciplines are not to be undermined. My thanks once again to all staff and students for their continued commitment to research.

Rights-based restitution in South Africa : developmental land reform or relocation in reverse?

  • Description: The main question of this thesis is to what extent the rights-based and market-driven nature of the restitution program has given rise to a legalistic and bureaucratic process that negates both the demand-driven and the developmental aspects of restitution as land reform. I answer this question by showing that the choice of a Constitutional model with a Bill of Rights provides the background for a rights-based land reform program. This is especially true for the restitution sub-program, one of the three branches along with redistribution and tenure of the overall land reform program. I then consider the debate around the property clause, and how its inclusion provided the context for a market and rights-based approach to land reform as opposed to a supply-led administrative approach. Because the property clause as a First Generation right prevents expropriation of land without market-related compensation, a complex and legalistic land reform program falling within the ambit of Second Generation rights was formulated to address the gross imbalance in land ownership in South Africa. I argue that the contemporary origin of Second Generation human rights lies within the context of class and anti-globalisation struggles for democracy, and that they are something to be fought for and defended. I discuss the distinction between First, Second and Third Generation rights and identify four spheres within which the struggle for Second and Third Generation rights takes place within modern democratic states. These are the state, the representative public sphere, civil society and the private sphere. I then deal with the problem of trying to turn "paper rights" into realisable rights for the more disadvantaged sectors of society. I also look at what impedes their realisation. I argue that a number of strategies are necessary to ensure the delivery of Second and Third Generation rights. These are an adequate legislative framework, a good communication strategy, the development of institutional capacity to deliver, and if all else fails, access to conflict resolution mechanisms. I consider the major impediments to the realisation of Second and Third Generation rights to be the way in which they are defined in relation to First Generation rights, especially the property clause, the way in which access to rights-backed resources through formal institutions are mediated by the operation of informal institutions, and the dearth of administrative competence in South Africa. My point is that in order for Second and Third Generation rights to have practical benefit for the dispossessed and poor, extraordinary measures are needed. The Restitution arm of the land reform program provides in theory just such extraordinary measures, albeit for only a section of the population. I analyse the effectiveness of the Land Claims Court in assisting restitution claimants and the rural poor to realize their rights. I trace the slow and haphazard shift from a positivistic statutory interpretation (narrow, literal, legalistic) to a purposive interpretation (informed by the Constitutional spirit and social purpose of the legislation) by the Court. This is followed by an analysis of the restitution business process, which means tracing the path of the claim from lodgement to settlement. I set out the costly, complex and legalistic implementation and policy process in some detail. My argument is that in order for a rights-based approach to overcome the impediments outlined in Chapter 3, as well as the property clause in the Constitution, its architects designed a complex process that in the end proved counter-productive in terms of its original aims. The failure of the process to deliver led in 1998 the then Minister of Land Affairs, Derek Hannekom, to appoint a Ministerial Review to investigate the problems. Problems included: slowness of delivery, the crisis of unplannability, low levels of trust between implementers, and high levels of frustration. Two issues are analysed more fully, the rights-driven approach as opposed to the rights-based approach and the lack of claimant participation in taking control of the restitution process. I examine the relationship of the Restitution Commission to the Department of Land Affairs and to municipal land use planning processes. The emphasis on rights within the restitution program had the effect of distancing restitution, especially in the first few years of the programs' existence, from the rest of the land reform program, as well as from the local government process of formulating land development objectives (LDOs), and the Integrated Development Planning (lOP) process. I look at the Port Elizabeth Land and Community Restoration Association (Pelcra) as a case study as it embodies an approach that tries to move beyond a mere reclaiming of rights in land and attempts to implement a developmental approach. I conclude that the rights-based restitution program in spite of its many shortcomings has had some success. It has moved slowly from an overly legalistic judicial program to a more administrative but still bureaucratic process, that has delivered only 27 percent of its product as land reform, the rest going to monetary compensation mainly in urban areas. Thus it can be argued that restitution has been more successful as a program to promote reconciliation along the lines of the Truth and Reconciliation Commission, than as a land reform program, especially if one regards land reform as the restoration of rural land to the indigenous population. There have also been some successful attempts by the Commission, such as in the case of PELCRA, to integrate the processing of its claims with local government planning processes, but progress in this direction remains patchy.

  • Description: This thesis uses the sustainable rural livelihoods framework to investigate the livelihoods of communities residing adjacent to a remote protected area on the Wild Coast. The communities living in the area are among the poorest in South Africa and are largely dependent on migrant remittances and state welfare grants for their survival. Soon after South Africa's first democratic elections in 1994, the communities lodged a land claim against the protected area on the basis of past removals. In 2001, their land rights to the protected area were restored, opening up new avenues for the development of the area. It is argued that livelihood systems in the area are complex, varied and dynamic, and that for development to be sustainable, it needs to be informed by a thorough understanding of the many factors that shape the context in which livelihoods are generated. The research is based primarily on 'in-depth' micro-studies of two villages in the area - Ntubeni and Cwebe. It includes a detailed assessment of the extent and distribution of poverty and the various factors that make households vulnerable to livelihood shocks. The role of the rich and diverse natural resource base, the property rights associated with it, and the under-development of infrastructure and services in the area, are discussed in relation to livelihood prospects. A systems approach is used to examine the various ways in which livestock husbandry, cropping, natural resource use, employment and welfare dependence interact. Finally, the thesis examines in some detail the distribution of household assets, livelihood strategies and livelihood outcomes between the two villages, and between households in different income groups.

  • Description: Rhodes Centenary issue , The small University of Rhodes (6142 students), in the rural city of Grahamstown, was established in 1904 as a result of a £50 000 grant from the Rhodes Trust in Oxford. It grew out of St Andrew’s College, which provided the first four professors and 41 students. The first paper from Rhodes in the South African Journal of Science (then called the Report of the South African Association for the Advancement of Science) was by Selmar Schonland, one of the university’s founding fathers. Entitled: ‘Biological and ethnological observations on a trip to the N.E. Kalahari’, it appeared in 1904. The following pages provide a glimpse into the growth and achievements of various departments in the faculties of Science and Pharmacy and associated institutes a century after the university was born.

  • Description: This paper summarizes the results of a women’s community-based marine protected area that has been successful in sustaining invertebrate biological resources and in promoting strong community support. We outline the project and the associated biological results, describe the processes involved in attaining a committed level of community participation, and review the lessons learned during the project’s implementation. We attribute the project’s preliminary success—improved shellfish biomass, enhanced local environmental awareness, and the reinvigoration of cultural management practices—to the following factors: 1) the high level of participatory involvement and community leadership; 2) the local perception that shell beds have recovered rapidly and the role that scientific evaluation has played in reinforcing this notion; 3) a research program that is cross-fertilizing indigenous and scientific ecological knowledge; 4) the unique marine tenure system that allows for the project’s development and the area’s policing; and 5) the tangible economic incentives created by the development project, which ultimately empowers local women. We hope that the project’s findings can be generalized to other regions of the world with operational sea-tenure regimes and that it can help to make the establishing of community-based marine protected areas (CBMPAs) across the Pacific region more effective.

  • Description: The white margined sole Synaptura marginata (Soleidae) was isolated as the most likely candidate for flatfish aquaculture in South Africa. The aim of the study was to screen the sole as a candidate aquaculture species by way of a comprehensive study of its biology and life history strategy and to identify possible "bottlenecks". The study was undertaken on the assumption that the biological data would provide valuable information for developing specific technologies that might be required for the farming of this species. Specimens were collected monthly by spearing along the Eastern Cape coast of South Africa between December 2000 and March 2002. Length-at-age data required for modeling the growth of S. marginata was obtained from sectioned otoliths. A Von Bertalanffy growth model with an absolute error structure best describes the growth for this species. The model parameters were: L∞ = 429.5 mm TL, K = 0.24 and t₀ = -1 .79 years. Analysis of gut contents showed that S. marginata feed exclusively on polychaete worms, mainly of the genus Morphysa. S. marginata shows a protracted summer spawning season of six months, from October to April. This was determined by the calculation of a monthly gonadosomatic index and a macroscopic maturity scale. Histological examination of the ovaries revealed five ovarian developmental stages. Size at 50% and 100% sexual maturity for females was calculated to be 235 mm TL and 300 mm TL (ca. 1.5 - 2.5 years of age) and all males> 154 mm TL were mature. S. marginata is a batch spawner, releasing a minimum of 3 batches of eggs per year. Relative fecundity is high (34000 eggs per year I kg) and this coupled with the protracted spawning season would make it possible to obtain adequate numbers of juveniles (for farming) for approximately five to six months of the year. Comparative analysis of the biological characteristics in relation to other soles farmed elsewhere in the world suggests that S. marginata is a suitable candidate for marine fish culture in South Africa.

  • Description: This project is concerned with the development of a search algorithm for a large archival database. The Port Elizabeth Genealogical Information System (PEGIS) contains a database consisting of almost 600000 individuals. The standard search algorithms are no longer sufficient to locate individuals in the database. A new algorithm was required that allows searches on any of the words or dates in the database, as well as a means to specify where in the desired record a word should occur. A ranking function of retrieved records was also required. A literature study on the field of Information Retrieval and on algorithms designed specifically for the PEGIS was done. These algorithms were adapted and hybridized to yield a search algorithm that allows for the boolean formulation of queries and the specification of the structure of search words in the desired records. The algorithm ranks retrieved records in assumed relevance to the user. The new algorithms were evaluated with regards to retrieval speed and accuracy and were found to be very effective.

  • Description: Smith's (personal communication) work in a continuous, commercial cabbage-growing area near Grahamstown showed that parasitism of diamondback moth averaged over 60% and could reach 100%. In many parts of the world cabbage crops are not under continuous cultivation, and periodic cropping Systems may demonstrate différent patterns of parasitism, especially in disrupted, patchy subsistence crops. Cabbage (Brassica oleracea) is the most commonly grown cruciferous crop in subsistence gardens in the suburbs of Grahamstown East. The subsistence farmers' crops are considered patchy because the cabbages are grown in small and relatively widely separated plots. Thèse gardens provided an opportunity to follow Talekar and Shelton's (1993) suggestion to investigate the population dynamics of P. xylostella (a useful model pest) and its rate of parasitism on cabbages of subsistence farmers where commercial pesticides are used less.

  • Description: This research was initiated due to declining customer satisfaction indices in the Southern region of Eskom, an electricity utility in South Africa. Given the link between customer satisfaction and purchase intentions, the sustainability of the business is at stake. The validity of the current MaxiCare survey tool is questioned and explored, as is the congruence of management and customers' perceptions regarding the key service quality constructs in the industry. The study's objective was to provide management with a reliable and valid customer satisfaction survey instrument as an alternate to the existing tool and to use the knowledge gained through the research process to recommend improvement strategies aimed at closing specific satisfaction gaps identified. The research was performed in two stages; firstly, semistructured interviews with customers and management to gain an understanding of the most important satisfaction dimensions. These influenced the design of a survey instrument based largely on the SERVPERF tool with the inclusion of importance ratings per item in the second stage. The quantitative survey results were used to assess the reliability and validity of the research and to suggest areas for future work. The results show that communication, quality of supply, assurance and price are uppermost in the consumer's mind. Tangibles are not significant and the inclusion of empathy is inconclusive. Management and customer perceptions at a macro level are closely aligned, however the two populations are not in agreement as to the underlying micro considerations. Similarly, the MaxiCare instrument is found to be valid as a macro indicator but lacks sufficient detail to be useful as a strategic tool and needs to be supplemented with additional sources of market information. The survey instrument used in the second phase is both descriptive and reliable but the number of factors it measures, the mix of items and the inclusion of the 'importance' dimension need further refinement to improve its validity. Future revisions of the tool will provide management with specific information that allows them to focus improvement strategies on disgruntled customers and their key service issues.

  • Description: Publisher version , Introduction: Contributors to the prostitution/sex work debate, whether they condone, support or oppose criminalisation, legalisation or decriminalisation of prostitution, often rely on ‘facts’ to support their arguments. A common fact is that the majority of prostitutes/sex workers in the world and in South Africa are women. Thus, when I refer to prostitutes/sex workers, I refer to women working as prostitutes in the commercial sex industry. Furthermore, the fact that the majority of sex workers are women justifies considering prostitution from a feminist perspective – women’s voices on the subject should be heard. In this note I shall use the terms ‘prostitution’ and ‘sex work’ to refer to the exchange of sexual services for money. The former, more conventional term has a negative connotation, while the term ‘sex work’ denotes a movement away from casting a moral judgment towards recognition that sex work is just another job. References will be made to the associated activities of brothel-keeping and pimping, but the focus of this note is mainly on the provision of sexual services by the prostitute/ sex worker herself. Jordan v S is a Constitutional Court judgment in which the constitutional validity of the criminalisation of prostitution and its related activities were challenged. In order to analyse this judgment from a feminist perspective, I shall first briefly set out the current legal position on prostitution. Thereafter, I shall give an overview of Western feminist perspectives on prostitution and then link this perspective with African feminism. The last part of the note will be an analysis of the Jordan judgment in light of the feminist perspectives identified before.

  • Description: Africa as no exception. It is generally accepted that women constitute the vast majority of sexual harassment victims. Sexual harassment is therefore one of the major barriers to women’s equality as it is a significant obstacle to women’s entrance into many sectors of the labour market. The Constitution now provides that no person may unfairly discriminate against anyone on grounds of, inter alia, sex and gender. The Employment Equity Act now provides that harassment is a form of unfair discrimination. It has been said that harassment is discriminatory because it raises an arbitrary barrier to the full and equal enjoyment of a person’s rights in the workplace. Much can be learned from the law of the United States and that country’s struggle to fit harassment under its discrimination laws. The Code of Good Practice on the Handling of Sexual Harassment Cases attempts to eliminate sexual harassment in the workplace by providing procedures that will enable employers to deal with occurrences of sexual harassment and to implement preventative measures. The Code also encourages employers to develop and implement policies on sexual harassment that will serve as a guideline for the conduct of all employees. Although the Code has been subject to some criticism, particularly regarding the test for sexual harassment, it remains a valuable guide to both employers and employees alike. The appropriate test for sexual harassment as a form of unfair discrimination has given rise to debate. Both the subjective test and the objective test for sexual harassment present problems. Some authors recommend a compromise between these two tests in the form of the “reasonable victim” test. The Employment Equity Act makes the employer liable for the prohibited acts of the employee in certain circumstances. The Act, however, places certain responsibilities on the employer and the employee-victim before the employer will be held liable for sexual harassment committed by an employee. Sexual harassment committed by an employee constitutes misconduct and can be a dismissible offence. An employer may also be held to have constructively dismissed an employee, if the employer was aware of the sexual harassment and failed to control such behaviour, and the employee is forced to resign. The test for determining the appropriateness of the sanction of dismissal for sexual harassment is whether or not the employee’s misconduct is serious and of such gravity that it makes a continued employment relationship intolerable. However, for such a dismissal to be fair it must be both substantively fair and procedurally fair.
