- Description: This study deals with the impact of HIV/AIDS on women living in chronic poverty. The question arises: Do we focus on their HIV/AIDS stories only or do we include their other lived experiences? This phenomenological study, on two sets of three generations of women infected and affected by HIV/AIDS and living in poverty, is an attempt at understanding the way the women experience their lifeworlds, not only their HIV/AIDS stories. One set includes a grandmother, her daughter who is living with full-blown AIDS, and her granddaughter, while the other includes a grandmother, her daughter and her granddaughter infected with HIV. The initial focus of the study was on the women’s HIV/AIDS narratives. However as the study progressed, especially during the interviews, it became apparent that the women’s generational poverty or chronic poverty was of greater concern to them than the HIV/AIDS that they were experiencing. Of the six participants, only one woman centred her life story on HIV/AIDS. This finding echoes other studies on HIV/AIDS among poor women: that chronic poverty is more threatening to the women than the risk or reality of AIDS. As a phenomenological researcher my aim was to focus on the participants’ own interpretations of the studied phenomenon. However, this was inadequate in accounting for the role that social structures play in shaping and informing the women’s subjective consciousness and experience. For this reason, I used feminist ideas to understand and interpret the women’s patriarchal experiences.

- Description: The general health status of pregnant women depends largely on the quality of the antenatal services available to them. The provision of good antenatal services ensures early detection and prompt management of any complication or disease that may adversely affect pregnancy outcome. In order to ensure high quality care, antenatal services need to be evaluated at regular intervals, both from provider and client perspective, to ensure their effectiveness in improving the health status of pregnant women. The midwife, as the first contact person for most pregnant women attending antenatal clinics in South Africa, has the potential to play a major role in improving the health status of these women. However, for the midwife to be effective in achieving this, antenatal services need to be effectively utilized by women. One of the factors that affect utilization of any service is client satisfaction with the service being rendered. This study, therefore, explores the perceptions that pregnant women have of the care that they receive from midwives at the selected antenatal clinics. The objectives of the study are to: {u100083} Explore and describe the perceptions and experiences of pregnant women attending antenatal clinic regarding the care they receive from midwives. {u100083} Make recommendations to assist registered midwives in optimizing the accompaniment of women during the antenatal period. A qualitative, descriptive, exploratory and contextual design was used for the study. The sample was chosen from the target population by means of purposive sampling and data was collected through unstructured interviews with the participants. Before data collection, permission was obtained from the Eastern Cape Department of Health and the Nursing Service Manager of the Gateway clinic, in the district hospital where the research was conducted. The Nursing Service Manager was acting as a Medical Superintendent at the time of the study. Written, informed consent was obtained from all participants before conducting interviews. Trustworthiness was ensured by means of Guba’s model throughout the study, and the aspects of truth value, applicability, consistency and neutrality were considered. Tesch’s eight steps of data analysis were used to analyze the data collected, and four main themes were identified namely: • Women perceive midwives as considerate and knowledgeable • Women perceive midwives as lazy and rude • Women experience mixed emotions about the care they receive from midwives • Though their experiences, women identified certain needs in the services and care they received at the clinic. Conclusions were drawn and recommendations for midwifery practice made based on the results of the study, with the aim of improving antenatal services rendered to pregnant women.

- Description: The promulgation into law of the concept of workplace forums has been beset with immense criticism and opposition from organized labour and some quarters of organized business. Last ditch efforts by the Ministerial Task Team had won the day for the inclusion of this controversial provision in the new Labour Relations Act.1 Commentators on the Act tend to agree that the fallout with organized labour at the negotiations has probably set the scene as to whether the provisions would be widely used or not. History has shown that the establishment of such forums in workplaces has been low. In some situations where workplace forums had been established, their continuous sustainability was put into doubt. This has led to the de-establishment of some of these forums in some workplaces. Various reasons were provided, but the prime factors for its failure could be traced back to the negotiations at NEDLAC. The unions opposed the original proposal by government that minority unions and even non-union employees can trigger the establishment of a workplace forum and insisted that this be restricted to majority unions. The voluntary nature regarding the establishment of a workplace forum and the trigger that only a majority union can invoke the provisions has still seen unions reluctant to utilize the provisions since it did not serve their purpose. The aims of the provisions, namely to increase workplace democracy, was therefore thwarted in favour of more informal procedures. Although the idea is a noble one, it is argued that the introduction of the provisions was ill-timed and inappropriate. The lesson that the legislature can take is that for any provision to be a success, buy-in from all stakeholders is paramount. Research has shown that there was a steady decline in the establishment of workplace forums. Since December 2004 there was not a single application received by the Commission for Conciliation, mediation and Arbitration. There is also doubt as to whether any of the Forums that were previously established are still functional. What is certain is that statutory workplace forums is not at the forefront as a vehicle for change that was envisaged in the Explanatory Memorandum that accompanied the new Labour Relations Act. What is also certain is that employers and employees are utilizing other forums to ensure workplace participation. These forums, however, only provide a voice to unionized workers. The vast majority of non-union workers remain voiceless. The proposed amendments in 2002 that intimated that the trigger be any union and not only majority unions failed to be passed into law. Perhaps it is that type of catalyst that is required to give life to the provisions. The future of workplace forums in South Africa is bleak and will continue to be if there is no intervention by the parties at NEDLAC to revive it. A complete revamp of the legislation would be required for such a revival. Some commentators have made meaningful suggestions on changes that can be made to the legislation to make workplace forums more attractive. Some have suggested it be scrapped altogether and future workplace participatory structures should be left to the parties to embrace voluntarily. Workplace forums are a novel innovation with great potential to encourage workplace democracy. There is nothing wrong with the concept. The application of such forums in the South African context is what is concerning. Perhaps prior experience and experimentation with similar type forums have tarnished workplace participation. The strategies by the previous regime and some employers have caused such participation to equate to co-option. Perhaps not enough spade work was done to ensure that the climate and attitude of the parties was conducive for its introduction. What is paramount no matter the form it takes is that workplace participation is crucial for economic growth and the introduction of new work methods to improve productivity. Without the establishment of such forums, whether voluntary or statutory, the ‘second channel principle’ that promotes non-adversarial workplace joint decision-making would be lost and conflict based participation could spiral leading to economic disaster.

- Description: What is the role of Drama Studies within the university? What is ‘the university’ and what purpose does it serve? Curzon-Hobson (2002: 181) maintains that ‘if one is to claim anything about the essential nature of the roles or values underpinning higher education, it can only be that it has become a site of increasing flux, ambiguity and inconsistency’. The very concept of ‘university’ and ‘academic knowledge’ has radically shifted with the development of postmodern thinking. ‘The notion of authoritative knowledge has been permanently undermined, for a postmoderist perspective suggests that all knowledge claims are local, partial and contextually specific’ (Luckett 2001: 54). Globally, universities are increasingly required to justify their existence, and we are witnessing a move towards ‘performativity’ (Lemmer 1998), as ‘disciplines are called upon to demonstrate their use-value in the global market’ (Barnett 2000b: 257). The South African context is no different. If, as many scholars have argued, the function of higher education has shifted so that the valued product of a university degree is not so much the quality of learning but the qualification gained (Race 1999), what is the place of the transient abstract texts of the discipline of Drama?

- Description: Written information to promote patient education is being increasingly recognized as an integral part of quality health care. The main objective of this study was to evaluate the effect of distributing a patient information leaflet (PIL) on knowledge acquisition and recall. Two different PILs were designed for co-trimoxazole tablets: a simple, shorter PIL that incorporated pictograms and text and a text-only PIL that was longer and more complex. Human immunodeficiency virus-positive participants on chronic co-trimoxazole therapy were enrolled from five local primary health care clinics in Grahamstown, South Africa, and were randomly allocated to a Control Group (no PIL), Group A (text-only PIL) or Group B (simple PIL with pictograms).

- Description: Investigation of comparative effects of feeding damage by the Russian wheat aphid (RWA, biotype SA1, Diuraphis noxia Mordvilko) on leaf blades of susceptible and resistant wheat cultivars (Triticum aestivum L. var Betta and Betta-Dn1 respectively) were carried out to establish the level of ultrastructural damage caused by this aphid and the possible limitation of damage induced which could be ascribed to the resistance gene Dn1 over the susceptible cultivar. Ultrastructurally, Betta-Dn1 sustained less damage to the vascular tissue as well as to the mesophyll during the experimental period. Both inter- and intracellular probes resulted in considerable saliva deposition as the aphids probed for suitable feeding sites. Salivary tracks were observed between and within mesophyll, bundle sheath cells as well as the vascular tissue, including the xylem. Disruption of organelles and cytoplasm resulted from cell probing and sheath deposition. Cell and organelle damage was more evident in the non-resistant Betta cultivar. The aphids probed for and fed from thin-walled sieve tubes preferentially. Few thick-walled sieve tubes showed evidence of either aphid probing or feeding-related damage. Saliva was deposited when the aphids probed inter- and intracellularly for feeding sites. The aphids appeared preferentially to probe for and feed from thin-walled sieve tubes, as few thick-walled sieve tubes showed evidence of damage. Vessels, apparently probed for water, contained watery saliva that encased the secondary walls and sealed pit membranes between probed vessels and xylem parenchyma. The xylem probed by the RWA was rendered non-functional, probably contributing to symptoms of leaf roll, chlorosis and necrosis, which were observed within two weeks of infestation in the susceptible Betta cultivar. This damage was limited in the resistant Betta-Dn1 cultivar during the same time frame.

The model proposed for individual animal identification is based on a combination of image processing and fingerprint identification technology. About 20 minutes of zebra footage was filmed at the Amakhala Game Reserve in South Africa. The study indicates that there is sufficient variation in lateral stripe patterns to differentiate individual animals.

- Description: preprint , This book is a primarily a study of Charles Kean’s productions of Shakespeare’s English chronicle plays at the Princess’s Theatre between 1852 and 1859, a period crucial to the development of ideas of English nationalism. Schoch focuses on these particular stagings as more than drama; as performances of nineteenth century theories of history and historical representation. His project operates under the aegis of the so-called ‘linguistic turn’ in cultural theory, and is suspicious of neo-marxian fundamentalism.
