- Description: Certain debris accumulations in Bottelnek are ascribed a rock glacier origin on the basis of morphological and sedimentological evidence. Radiocarbon dating indicates that rock glaciers were active at or subsequent to 21 000 BP and that cold, stadial conditions, existed on the region after 27 000 BP and before 13 000 BP, during the Bottelnek Stadial. At least sporadic permafrost existed in Bottelnek when the rock glaciers were active.

- Description: This research study is a qualitative investigation of the role of the industrial social worker in corporate community relations. The research study was undertaken by means of mailed questionnaires. Two different populations were utilized, namely corporations known to practice corporate social responsibility and corporations employing industrial social workers. As a background to the research, relations is defined and its Furthermore, the contribution of relations in the realization of a corporate development community traced. corporate community government-business partnership to address community social problems, is discussed. Lastly, in an attempt to demonstrate that the social worker can indeed play a role in corporate community relations, the extent to which corporate community relations goals and approaches correspond with the community organization model of social work practice, is examined. The purpose of the empirical part of the research study was to determine what form community relations has taken in South Africa and the role that the industrial social worker assumes in this regard. From the findings it appears that there is a focus on philanthropic activities and less direct corporate involvement in creating new resources. Industrial social workers involvement in this function was limited. They primarily assumed the roles of consultant and expert. Although these social workers' have laid the ground work for expansion of the industrial social worker's role, it appears that development has been more serendipitous than rationally planned. It appears from the findings that the potential does exist for industrial social workers to assist the corporation to expand its social responsibility programme, and in so doing expand their practice to include macro level intervention strategies. Based on these assumptions, it is suggested that further in-depth research is carried out to establish what strategies are being employed by industrial social workers to expand their roles, it appears that there is a need to assist the industrial social worker to adopt a rationally planned approach in order to assume a greater role in the corporation's social responsibility activities internally and externally.

- 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: Guidance was introduced into Black Schools in 1981. Its aim was to help students so that they could understand themselves and the world they live in. At present it appears that very little Guidance is taking place in the Mdantsane High Schools. This was supported by these research findings. In the research five High Schools were investigated to discover the state of Guidance in these High Schools. The writer made use of an interview schedule which was presented to the principals of the five High Schools. Questionnaires were given to twenty seven Guidance teachers from the same High Schools and to two hundred and fifty student respondents. In each High School fifty student respondents were chosen, that is, ten from each standard. The research findings suggested that Guidance is not receiving its rightful place in these five High Schools since it is not effectively taught. The findings were generalised to other High Schools. Reasons for the ineffective teaching of Guidance were given by both the principal and teacher respondents. Recommendations are made as to how this state of Guidance can be remedied and improved.

- 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: The Sycoecinae are a distinct and well-defined subfamily of old world fig wasps (Agaonidae, Chalcidoidea 1 Hymenoptera) , exclusively associated with the figs of Ficus species (Moraceae). The most likely sister group of the Sycoecinae was determined to be the Sycoryctini (Sycoryctinae) based largely on synapomorphies of the underside of the head. 67 sycoecine species and 3 subspecies were recognised and included in a phylogenetic analysis of the subfamily. This analysis clearly delimited six genera (four African and two extra-African), although the phylogenetic relationships between the genera were not strongly supported and remain flexible. Comparisons of the phylogeny of the Sycoecinae with the classifications of the Agaoninae and their host fig trees (Ficus, Moraceae) suggest a degree of cospeciation sensu lato. Numerous homoplasies were detected within the Sycoecinae, some of which were shared with another group of fig wasps that also enter the fig to oviposit, the Agaoninae. The anatomy of the figs apparently provides strong selection pressures that have resulted in both parallelisms and convergences within and between the two subfamilies. Among the 67 species and 3 subspecies that were recognised, 43 species and 2 subspecies are described as new. The males of three previously recognised species are also described for the first time. One generic and two specific synonyms are established together with five new combinations. Keys are provided to the genera and species, for both sexes.

- Description: The thesis is presented in two parts. In part one, the excess thermodynamic properties have been determined for several binary liquid mixtures, with the aim of testing theories of liquid mixtures. The excess molar enthalpies, Hem, have been determined using an LKB flow microcalorimeter, and the excess molar volumes, Vem, have been determined using an Anton Paar densitometer. The HemS and VemS have been measured at 298.15 K for binary systems involving an alkanol (methanol, ethanol, I-propanol, 2-propanol) mixed with a hydrocarbon (l-hexene, I-heptene, l-octene, I-hexyne, I-heptyne, l-octyne, toluene, mesitylene, 0-, m-, or p-xylene, cyclopentane, cyclohexane, cycloheptane, cyclooctane, cyclodecane). The results show trends relating to the degree of unsaturation, or size, of component molecules as well as the position of the hydroxyl group on the alkanol. Measurements were also made on mixtures involving an (n-alkane + a pseudo-n-alkane) and ( a cYcloalkane + a pseudo-cycloalkane). Two theories of liquid mixtures were tested in this work. The first theory tested was the theory of Congruency. This theory was tested, by means of a null test, on a novel set of mixtures involving an n-alkane (hexane, heptane, octane, decane, dodecane) + a pseudo-nalkane,and mixtures of a cycloalkane (cyclopentane, cyclohexane, cycloheptane, cyclooctane)+ a pseudo-cycloalkane. Deviations from the theory was less than the experimental error for the (n-alkane + pseudo-n-alkane) mixtures. However, significant deviations were observed for the mixtures of (a cycloalkane + a pseudo-cycloalkane). The second theory tested was the Flory theory, which has been used to predict the excess molar enthalpies and excess molar volumes for the mixtures involving (a 1-alkene, or 1-alkyne, or methyl-substituted benzene) + an alkanol. The results show that the theory does not hold for hydrocarbon mixtures involving an alkanol. In the second part of this thesis, the partial molar volumes, at infinite dilution, of binary solution involving a solid solute (18-crown-6 ether, dibenzo-18-crown-6 ether, dicyclohexanov 18-crown-6 ether, 15-crown-5 ether, or cryptand-222) are determined in various solvents. The results were repeated with a view to determine the volume changes at infinite dilution upon complexation, ΔV∞ of the crown ether or cryptand with a metal halide salt, MX (NaCl, NaI, KCl, KI, CsCl, CsI). The ΔV∞ results were compared with results in the literature for cryptand-222 (c-222) and dibenzo-18-crown-6 ether (B₂CE6) complexed with MX, and the study was extended to include further MX complexes with c-222 and B₂CE6, as well as MX complexes with 15-crown-5 ether and dicyclohexano-18-crown-6 ether. ΔV∞ results were correlated with the Hepler prediction of the electrostriction solvent effect.

Examination of high-resolution electronmicrographs, and computer-enhanced digital images suggests that these plasmodesmata are complex structures, comprised of helically-arranged particulate material. The electron-dense particles are between 2.5 and 3.0nm in diameter. These particles are specifically associated with the inner face of the inner plasmalemma membrane leaflet, and the outer region of the desmotubule wall. The electron-dense particles are presumably proteinaceous and embedded in a lipid matrix. In the constricted median portion of the KMS-BS plasmodesmata, the space between the desmotubule and the inner plasmalemma membrane leaflet and areas surrounding the proteinaceous particles thereof (the cytoplasmic sleeve) is about 3nm in cross-section, and constitutes what we believe to be the space through which intercellular transport takes place.

- Description: Current theories in geographical education advocate the use of strategies that encourage the pupil to play an active role in learning, thereby making such learning more meaningful and effective. Fieldwork is perceived as one such method. Fieldwork helps pupils acquire and develop understanding of geographical concepts, skills, attitudes and values through their own efforts and involvement. Fieldwork approaches have tended to change with the changing paradigms resulting in the development of approaches that are more pupil and experience oriented. In the South African school geography curricula fieldwork has been explicit since 1985. However, research has shown that in most South African secondary schools fieldwork as a teaching strategy is only applied to a limited extent. Teachers have always used financial constraints and time limitations as explanations for their failure to use fieldwork in teaching geography. This study attempts to demonstrate how the local environment of any school can be used effectively for teaching and learning most aspects of the senior secondary school geography syllabus, thereby alleviating the problems of time and money perceived by teachers as the major constraints inhibiting their use of fieldwork. In order to illustrate the effectiveness of fieldwork in the local environment, this study incorporated an analysis of the current senior secondary school geography syllabus, the identification of potential fieldwork sites in the Umtata District and the development and implementation of three fieldwork units based on three of the sites identified. The analysis of the evaluations of the three fieldwork units by the researcher, the pupils and the non-participant observer revealed that fieldwork conducted in the local environment is highly effective, interesting and rewarding to pupils even when they have no prior experience of fieldwork.

- Description: Current theories in geographical education advocate the use of strategies that encourage the pupil to play an active role in learning, thereby making such learning more meaningful and effective. Fieldwork is perceived as one such method. Fieldwork helps pupils acquire and develop understanding of geographical concepts, skills, attitudes and values through their own efforts and involvement. Fieldwork approaches have tended to change with the changing paradigms resulting in the development of approaches that are more pupil and experience oriented. In the South African school geography curricula fieldwork has been explicit since 1985. However, research has shown that in most South African secondary schools fieldwork as a teaching strategy is only applied to a limited extent. Teachers have always used financial constraints and time limitations as explanations for their failure to use fieldwork in teaching geography. This study attempts to demonstrate how the local environment of any school can be used effectively for teaching and learning most aspects of the senior secondary school geography syllabus, thereby alleviating the problems of time and money perceived by teachers as the major constraints inhibiting their use of fieldwork. In order to illustrate the effectiveness of fieldwork in the local environment, this study incorporated an analysis of the current senior secondary school geography syllabus, the identification of potential fieldwork sites in the Umtata District and the development and implementation of three fieldwork units based on three of the sites identified. The analysis of the evaluations of the three fieldwork units by the researcher, the pupils and the non-participant observer revealed that fieldwork conducted in the local environment is highly effective, interesting and rewarding to pupils even when they have no prior experience of fieldwork.

The work of the Reverend James Cameron of the Wesleyan Methodist Missionary Society from 1829 to 1835

- Description: The name James Cameron is not a familiar one. Despite being one of the missionary pioneers of Methodism in southern Africa, serving for more than forty-six years in various districts and being elected as chairman of two of these districts, very few people have ever heard of James Cameron. Barnabas Shaw says of Cameron that he "excelled in preaching the great truths of the gospel, and applying them to the heart of sinners".¹ Whiteside describes Cameron as a "remarkable man ... well read in most things".² W.B. Boyce pays Cameron an even greater tribute: In my day, as a preacher and as a theologian, he was unequalled in South Africa; and I do not think that he was second in these respects to any of his brethren in England.³ Notwithstanding the high esteem in which he was held by prominent peers, Cameron is mentioned only in passing in a few secondary sources, and to date has not been the subject of academic research. The reason for this is not clear. He was well educated, read and wrote extensively, and most of his correspondence has been preserved. Cameron's Journal is very well written, containing some beautiful poetic sections. It is a personal record of a missionary coping with peculiar and difficult circumstances, and a record of how determination, courage and faith enabled Cameron to overcome seemingly insurmountable difficulties. Cameron's recording of his struggles help fill out our understanding of missionaries and their tasks and problems in the nineteenth century. I believe that so important a figure in South African Methodism should be examined and deserves a definitive study. The aim of this thesis has been to provide a reference to his work in the western Cape, possibly to form a basis for closer historical scrutiny. ¹ Shaw 1840:232 ² Whiteside 1906:374 ³ Boyce 1874:179-80.

- Description: The mixed metal oxalates, FeCu(ox)₂.3H₂0, CoCu(ox)₂.3H₂0, and NiCu(ox)₂.3.5H₂0, [ox = C₂0₄] have been prepared by coprecipitation from solution. The thermal behaviour of these compounds in nitrogen and in oxygen has been examined using thermogravimetry (TG), thermomagnetometry (TM), differential scanning calorimetry (DSC) and evolved gas analysis (EGA), and results are compared with results obtained for Cuox and Mox.yH₂0. The thermal behaviour of the mixed oxalates, MCU(OX)₂.xH₂0, differed from that of the individual metal oxalates, Cuox, Coox.2H₂0, Niox.2H₂0 and Feox.2H₂0. All three mixed oxalates on heating in N₂, first dehydrate and then decompose in at least two overlapping endothermic stages. Both CO and CO₂ were evolved in proportions which varied with the surrounding atmosphere, and from compound to compound, and with extent of reaction of a given compound. The mixed oxalates, MCU(OX)₂.xH₂0, do not show the exothermic behaviour characteristic of Cuox, and reasons for this are discussed. Thermochemical calculations were done and the enthalpies of formation of the hydrates and dehydrated oxalates were determined. It was found that the enthalpy of mixing was very small or within experimental error. X-ray powder diffraction patterns for the individual and mixed oxalates were compared. The pattern for Cuox differs from the patterns obtained for the other oxalates, confirming suggestions that Cuox has a structure different to most other transition metal oxalates. The kinetics of dehydration and decomposition of the mixed oxalates were investigated, using isothermal and programmed temperature TG and DSC experiments. The yield and composition of evolved gases during isothermal decomposition were measured and compared with the enthalpy changes. X-ray photoelectron spectroscopy studies provided some information on the electron environment of the metal atoms in the various oxalates.

Ultrastructural development in the corpus allatum of the adult worker honey bee

- Description: The ultrastructure of the corpus allatum of the Cape worker honey bee has been examined in a systematic way during the first thirty days of adult life. Corpus allatum size in the Cape worker honey bee shows the age-dependent increase typical of the European worker honey bee, and in the Cape worker bee, the duration of increase is protracted. Analysis of ultrastructural development provides three indicators of metabolic status: mean mitochondrial size, "light and dark" cells, and extracted vacuoles. Significant fluctuations in mean mitochondrial size indicate a cyclical nature of cellular activity. New thought on the nature of "light and dark" cells proves that "dark" cells are almost certainly active in the process of JH biosynthesis, whilst "light" cells are definitely not active in JH biosynthesis. Extracted vacuoles found in corpus allatum cells during this study are thought to be remnants of lipid vacuoles, and the build up in number of these vacuoles is regarded as an indicator of reduced biosynthetic activity. Since the two indicators of decreased JH production ("light" cells and extracted vacuoles) co-exist with smaller mean mitochondrial size, larger mean mitochondrial size is taken as indicating increased levels of JH biosynthesis. Hence, fluctuations in mean mitochondrial size suggest cycles in the levels of JH production in individual corpora allata of the adult worker honey bee.

- 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.

I dare say you would then have joined the ranks of independent Africa. The key issue will still remain not addressed: who should centres of research and learning serve and how? This is why I think the real challenge for all of us, whether south or north of the Limpopo, whether black or brown, yellow or white, is to begin thinking of how to root African universities in African soil.

Read an amazing story about Argentina on page 10 about young boy who was stolen. It is a story about courage - the courage of women who stood up and demanded that the government find their children. This issue is also packed with lots of things to win. We've got FIVE great competitions that will get you thinking, drawing and making things. Don't miss the competition for an ISM computer on page 20, or the school bursaries competition on page 36. There are also competitions for music and books.

- Description: Thousands of young people are not at school. Many more can't find jobs or are homeless with little to eat. Others are frightened and scarred by the violence that surrounds them. Apartheid has brought hardship and pain to millions of people in this country. Ongoing violence, poverty and poor schooling have left over three million young people without a decent education, jobs or opportunities to develop their talents. These young people have come to be known as 'marginalised youth.' Apartheid has left them with little hope for the future. The government doesn't care about them. Often their own families can't help them either. But they have not been forgotten. At the National Youth Development Conference youth, parents, teachers and political leaders debated and discussed ways to solve the problems of marginalised youth in our country.
