- Description: The idea to restructure the union is not a new one. Political changes in our country compelled almost all the unions to consider the possibilities of restructuring the union and the industry in general. New approaches to Collective Bargaining Strategies came to the fore. The good example of these Bargaining strategies was the NUMSA THREE YEAR BARGAINING STRATEGY (1993). Later in the same year, CWIU also introduced its Bargaining Strategy in the form of five pillars. The common thing about Numsa and CWIU bargaining strategies is that they both failed to deliver and the process of setting up working groups are more complex than expected. The main cause of the tap problem in my view is that the existing union structures are a big deterent to the development and implementation of new bargaining strategies. Our Centralised Bargaining victory and the new LRA will demand major union restructuring if we want to utilise the openings created by these new developments. In this discussion paper, I will focus on how we should restructure our union. In this paper, I am suggesting that the union (CWIU) must be made up of four semi-autonomous departments.

- Description: Our National Congress is the highest decision making body of the Union. Its main task is to adopt resolutions that become the policies of NUMSA. These policies guide the union on how to act until the next Congress. After previous Congresses, we have only published the adopted resolutions. But this has meant that our members have lost out on the lively debates that have taken place during the Congress. In this booklet, we try and bring the Congress alive for you. We give you the full text of the General Secretary’s report, the debates as they took place, word for word. What was decided on the Alliance? Why do we want “nationalisation without compensation”? What was the decision on the Working Class Party? The final resolutions that were adopted are there for you to see. Extracts from speeches of various speakers are also given. Two key issues - the contents of the Reconstruction Accord and Restructuring Industry - will continue to be discussed in the Union. (The documents are included; see pages 65-82) Congress mandated the next Central Committee in October 1993 to take decisions on these issues. Use the booklet to find out for yourself what was said. You will be able to see what were the reasons given for the different positions. This will help you explain to members why NUMSA has adopted these resolutions. You will also see how democracy takes place. In some cases, compromises were reached, in other cases there was no compromise and the motion had to be put to the vote. Comrades, as our new President, Cde Tom, said in the Congress - “Our primary duty is to serve the interests of our members and those who have elected us to represent them. It is therefore necessary for us to be accountable to them in shaping the policies of the union. Most of the time we do not consult our members when we debate issues - even on minor issues we leave them behind It is very dangerous for us to create a distance between ourselves and our members. The members must not follow but must be there with us. We must remember our base is the factory floor.’ Use this booklet as a tool to get rid of that distance between you and the members. Use it to help you understand the positions that NUMSA has adopted as its policies. The General Secretary’s Report also gives a full picture of how NUMSA functions and gives useful background information to many of the discussions. The Tables mentioned are at the back of the book; see page 83 to the end. In this first section the debates and the speeches have been put into shaded boxes so it is easier for you to read. Use the booklet to build, strengthen and consolidate our Union in these difficult times.

What can TOLs reveal about the nature of ESL reading? : a critical evaluation of current ESL research utilising think-aloud protocols

- Description: This thesis explores the efficacy of think-aloud protocols (TOLs), and the extent to which the TOL technique is able to reveal the nature of ESL reading interaction with expository prose. The investigation constituted a critical evaluation of current ESL TOL research, which was essentially a theoretical examination of emerging problems derived from an in-depth assessment of current ESL TOL studies. The theoretical examination was supplemented by the practical implementation of the technique in a case study research, utilising three verbal protocols obtained from ESL students at the University of Fort Hare. The close observation afforded by the evaluative case study research paradigm provided the writer - as participant observer - with a further means of judging the merit of TOLs, which corroborated findings from the theoretical evaluation, and enabled a consideration of unanticipated issues which emerged from the practical implementation of the technique. The conclusion was that TOLs seem to have a unique ability to identify aspects of the nature of ESL reading gained from an on-line assessment of reader interaction, provided that TOL research is conducted within certain methodological and analytic research constraints. The writer has proffered suggestions for future ESL TOL research, and feels that the combination of TOL research findings with other measures of reading comprehension could elucidate aspects of ESL comprehension, making a valuable contribution to ESL reading theory and practice.

The role of the international community in the South African transition: a critical review

- Description: There is a dearth of position papers on international participation in the South African transition. Political parties and organisations in South Africa instead spend most of their time describing various forms of desirous IC intervention after the transition. This might explain why most articles and academic papers on 'the role of the international community' are suffixed - in the 'new South Africa' or 'post-apartheid South Africa' - few focus on the actual transition and then mostly from a systemic perspective, broadly outlining the constraints imposed by the 'new world order'. Perhaps the first serious attempt to address this gap in the debate over South Africa's future was D. Kempton and L. Mosia's 'The International Community in South Africa's Transition to non-racial Democracy' (1992). Before multiparty negotiations collapsed in June 1992, Kempton and Mosia examined the attitudes toward international intervention of most of the CODESA participants, as well as the major actors that had remained outside CODESA. This paper takes up the issue where Kempton and Mosia left off. It tries to explain transitional politics since the IC introduced an on-the-ground presence after the UN Security Council debates on South Africa in July 1992. It asks why, eight months after multiparty talks were suspended, the IC has been unable to revive multiparty negotiations, has apparently had little or no impact on the violence, and despite events like Boipatong and Bisho, still plays a minor peacekeeping role, confined to observer status. The research describes internal and external components of international intervention, examines the rationale behind the agreed forms of international participation, and assesses the viability of the internationally-supported conflict-resolution and transition-management structures that were formed to facilitate the transition. The evidence uncovered by the research leads the author to the conclusion that more of an international role is necessary, and sooner rather than later, but he concedes that this is not feasible, or likely, under the status quo.

- Description: Faced with problems related to the sustainability and advisability of contemporary irrigation development in Africa, anthropologists have increasingly looked to economic and political explanations for the success or failure of those development schemes. Instead of seeking explanations in these isolated areas, this thesis has argued that irrigation development needs to be understood through relationships within and between politics, economics, social structure and culture. In order to uncover those interactions with regard to the Tyefu Irrigation Scheme in the southern African homeland of Ciskei, reference has been made, firstly, to the mechanisms underlying contemporary state expansion and secondly, to the interaction between external forces, structures and surface forms through time. Anthropological fieldwork techniques have been used to provide detailed descriptions of everyday communications within and between groups associated with the development. Ethnography allows implementation to be conceptualized in terms of the interaction between local level structures and structures associated with the planning and construction of irrigation development itself. When the effect of external forces on the interaction between structures and forms is then taken into account principles emerge that reflect local and historical transformations. These in turn suggest the form of contemporary state expansion in southern Africa, as well as its bearing on daily life on the rural periphery.

- Description: School guidance and counselling is a programme that is complementary to the education process and is seen as a support service for the pupil. However, owing to the apartheid policies of the South African government, all pupils did not have equal access to guidance services. In a post-apartheid South Africa it is anticipated that a unitary education system would emerge to provide equal access to education for all South African pupils and this implies that previous imbalances that existed would have to be addressed. In this study the present state of guidance and counselling services in Natal was investigated and policy options to redress past inequities and to make school guidance and counselling services a reality for all South African pupils, within the context of limited resources were explored.

- Description: This thesis analyses the establishment of a health and safety system on the Witwatersrand gold mines in the period between the end of the South African War and the eve of World War Two. The period has been chosen, firstly, because the South African War had seriously disrupted production and the industry virtually had to start up again from scratch; secondly, because it was during this period that mine and state officials began to seriously investigate the reasons for the appalling mortality and morbidity rates on these mines; and, thirdly, because during this period some improvements did occur which were significant enough to enable the industry to warrant the lifting, in the latter part of the 1930s, of the ban on tropicals, enforced since 1913 as a result of their extremely high mortality rate. In the first thirty years of the twentieth century about 93 000 African miners died disease-related deaths and in the same period some 15000 African miners were killed in work-related deaths. In attempting to establish why so many African miners died, the thesis attempts to identify the diseases and accidents that caused these deaths and considers what attempts were made to bring mortality and morbidity rates down. Whilst the thesis is neither a history of gold mining in South Africa nor an economic history of South Africa in the period 1901 to 1939, it nevertheless, as detailed in the first chapter, places the health and safety system within the context of the wider political and economic forces that shaped the mining industry in this period. The need for a productive and efficient labour force, vital for the industry'S survival during a number of profitability crises in this period, forced the industry to reassess compound structures, nutrition and eventually the health of its work force. These issues of compounds, work and diet are discussed in chapters two, three and four. Appalling living and working conditions led to a high incidence of pulmonary diseases - TB, silicosis and pneumonia - which were the principal killers on the mines. Attempts to cure or prevent their occurrence are discussed in chapter five. Fear of disruptions to production ensured that the mining industry eventually also devoted considerable resources to accident prevention, a theme which is discussed in chapter six. The thesis concludes that the mining industry for much of this period was able to determine the pace of change; neither state officials nor African miners were able to significantly alter the tempo. In fact the industry was so successful that it was able to convince a number of government commissions in the 1940s that the migrant system had to stay, to ensure the wellbeing of the miner. This meant that despite considerable time, money and effort being spent on establishing a health and safety system on the gold mines, the mining industry was still of the opinion that the health of their workers was best served if they were sent home.

The effect of hydrostatic carbon dioxide pressure and extracellular ethanol on the performance of the yeast strain Saccharomyces cerevisiae during fermentation

- Description: The brewing industry constantly experiences problems in trying to maintain the quality of beer produced. Unfavourable conditions during fermentation may alter the performance of the yeast strain Saccharomyces cerevisiae, resulting in a "poor" end-product. It has been established that high concentrations of extracellular ethanol, when added to the fermentation medium inhibit yeast activity. It has been recently suggested that increased carbon dioxide pressure could inactivate the yeast activity adding to further brewing problems. The aim of this study was to investigate the effect of extracellular carbon dioxide pressure and ethanol addition, on yeast performance when added to a fermentation medium, and to establish whether an inhibitory relationship existed between ethanol and carbon dioxide pressure, when combined and added to the fermentation medium. Dissolved C0₂ in the medium, medium pH and substrate utilisation were analysed daily during a fermentation, as were membrane fatty acid composition. These parameters were used to assess the effect of ethanol and carbon dioxide on the yeast performance and consequently the final end-product. Supplementing the medium with extracellular ethanol, even as low as 5%, was shown to inhibit yeast performance during fermentation. This effect was even more marked as the ethanol concentration was increased, with almost total inhibition of yeast activity occuring after the addition of 15% ethanol (v/v). A similar effect was observed when elevated C0₂ pressures were applied to the medium, and although low C0₂ pressures initially induced the synthesis of saturated yeast membrane fatty acids, elevated C0₂ pressures (greater than 1,0 atm.) was shown to follow a similar inhibitory trend, if not as dramatic, as ethanol. A combination of both ethanol and C0₂ pressure showed a further increase in the level of yeast inhibition, although the low C0₂ pressure appeared to initially inhibit the toxicity of ethanol on the yeast. Increasing the levels of the C0₂/ethanol treatment (1,0 atm.), showed a synergistic effect on yeast performance. The results of this study indicate that both extracellular ethanol and carbon dioxide do appear to inhibit yeast performance and affect membrane fatty acid composition of the cells by inhibiting the synthesis of the respective fatty acid. This affect has a significant bearing on the general metabolism of the yeast cell.

- Description: Diarrhoeal disease is a major cause of mortality in children in developing countries. It also remains a serious problem among all age groups throughout the world. Whereas studies to determine the epidemiological and aetiological factors of diarrhoeal disease have been reported for other parts of South Africa and the world, as yet no information is available for the Eastern Cape. Therefore this study was undertaken to determine the factors for this area. Enteropathogens were compared for the different ages in the various population groups and, where possible, seasonal and geographical differences were emphasised. A total of 7 278 faecal samples were examined by six laboratories in the Eastern Cape during the period November 1988 to October 1990. Data was recorded noting the age, sex and population group of the patients. The towns selected were Port Elizabeth, Uitenhage, Cradock, Grahamstown and their surrounding areas. The isolation rates for the pathogens studied in the various population groups were compared to those reported in similar studies in other countries. The seasonal incidences of the various selected pathogens were compared with those reported from elsewhere in South Africa. It was thought that the higher temperature of summer may influence the finding in the White population group, while rainfall would play a greater role for the Coloured and Black populations. The geographical distribution of the pathogens emphasised the difference in living conditions between the different population groups. For example a generally higher infestation rate of Helminths occurred in rural areas and in the groups living under poorer conditions. The low isolation rates for certain bacteria and the large percentage of samples from which no pathogens were isolated indicate the need for further research. However, the finding should be valuable for determining Public Health priorities and in the management of outbreaks of diarrhoeal disease.

- Description: This study focuses on the taxonomy, biogeography and biological aspects of the fishes of Tristan da Cunha and Gough Island in the cental South Atlantic Ocean. Oceanographic measurements were undertaken to determine the position and nature of the Subtropical Convergence (STC) in the vicinity of the islands. The Tristan da Cunha group is thought to be situated on the northern edge of the STC while Gough Island is situated on the southern edge of the front. The seasonal environmental cycle at the islands is characterised by an annual sea surface temperature fluctuation of approximately 5 °C and an annual change in stratification of the water column. It is suggested that this increase in stratification at the STC, brought about in the summer by insolation warming the surface layers of the ocean, enhances primary production. The STC is identified as a unique habitat for fishes and as an important barrier to dispersal of species in the Southern Ocean. The present study has produced 18 new distributional records from the shelf waters of Tristan da Cunha and Gough Island. The fish fauna known from the shelf waters of these islands is reviewed, and a diagnosis, synonymy, and in some cases an illustration are provided. For certain species, brief notes on their biology, relative abundance and seasonal distribution are included. An analysis of the ichthyofaunal relationships between shallow water areas in the vicinity of the STC has resulted in the identification of a characteristic neritic STC ichthyofauna. The circumglobal distribution of many of these species is thought to be a consequence of a dispersive pelagic phase in their life-cycles. Biological processes in fishes at these islands are temporally and spatially affected by seasonal changes in oceanographic conditions. Seasonal sea temperature variation was identified as being an indicator of other oceanographic phenomena that may affect processes such as growth, reproduction and feeding in fishes at the islands. Most species have a summer spawning season and growth rate increased during the summer months. It was hypothesised that enhanced primary production and a related increase in food quality and availability during the summer were the major factors temporally regulating the growth and reproduction of fishes at the islands. Twenty families of neritic fishes have been recorded in the shelf waters of Tristan da Cunhaand Gough Island. Most families are represented by only one species. Because of this a wide range of life-history strategies are apparent in the fauna. Nevertheless, there are a number of common life-history characteristics shared by most of the neritic species. Firstly, the early lifehistory of many species included an extended pelagic phase which might have facilitated colonisation throughout the STC zone in the past, thereby regulating extant species diversity in this region. Secondly, the common occurrence of an extended summer breeding season and iteroparity suggested that these characters also contributed to survival in what is considered to be an unpredictable environment. It would appear that these common characteristics hold the key to the success of many fishes in the STC zone. This study has contributed to our understanding of oceanic island ecosystems and has revealed distributional patterns of fishes that were unknown previously. By focusing on the biological processes of selected species the regulatory role played by local environmental conditions became apparent. The results of this study are also relevant to proposed conservation measures for Tristan da Cunha and Gough Island.
