Description: The present study examined the effects of socio-economic status, quality and level of education on performance on the Wechsler Adult Intelligence Scale 3rd Edition r.:w AIS-III). The study was conducted within the context of the present Human Sciences Research Council (HSRC) W AIS-III standardisation process, cross-cultural psychometric research and the notion of test-wiseness. A South African sample (N = 68) comprising African first language (n = 40) and English first language (n = 28) participants, stratified for age (19 - 30 years), gender and educational attainment (Matric and Graduate) were utilised. Effects due to quality of education were determined by dividing the African language participants into those with private/model C schooling (n = 20) and those with DET schooling (n = 20). Effects due to level of education were determined by dividing the entire sample into those with Matric level education (n = 34) and those with Graduate level education (n = 34). Detailed demographic and socio-economic information were recorded for all participants, who completed the entire American version of the W AIS-III. Results revealed a highly significant positive correlation between high socio-economic status and W AIS-III Full Scale IQ. In addition the respective impact of the relatively poor quality of education and lower level of educational attainment on W AIS-III performance was substantial. These results were discussed in terms of their implications for cross-cultural research, the HSRC standardisation of the W AIS-III and the practical use of the W AIS-III in neuropsychological assessment.

Description: There is consensus that high CO2 results in enhanced growth and yield for most crop plants. However, most of these studies were carried out in the presence of adequate nutrients, which is also the case in agricultural systems (managed ecosystems). About 20% of the earth’s land mass have sufficiently low levels of nutrients to cause some kind of stress to plants. On the other hand, elevated [CO2] decreases foliar nutrient elements in plants and as a result partitioning of certain nutrient elements in plants is altered. Little data is available on the partitioning of most nutrient elements in plants, and this will definitely impact on growth and yield. To investigate this, wheat (Triticum aestivum L. c.v. Gamtoos) was grown in controlled environment cabinets at 360 and 700 µmol mol -1 CO2. The full Long-Ashton nutrient solution comprising of three-nitrogen concentrations ([N]) viz. (4,6 and 12 mM) was used to water plants everyday. The measurement of net assimilation rate (NAR), stomatal conductance (gs), transpiration rate (E), water use efficiency (WUE), foliar [N], nitrogen use efficiency (NUE) and growth parameters (total plant biomass (TPB), total plant height (TPH), leaf area (LA), shoot and root dry weight) were made 7 days after germination (7 DAG) till the onset of flowering. The increase in nitrogen supply in the order of 4, 6 and 12mM resulted in an increase in NAR, g_s_ , WUE and a decline in E under elevated [CO2]. Under elevated [CO2] NAR was observed to increase during the first two weeks reaching its maximum at 14 DAG, thereafter followed by a decline reaching its maximum at 28 DAG. This was later followed by an increase at 35 DAG onwards. Under elevated [CO2], NAR was increased significantly between the nitrogen regimes during the first (7-14 DAG) and the last two (35-42 DAG) weeks. The response of assimilation as a function of internal [CO2] (Ci), showed a decrease with age at ages 14, 28 and 35 DAG. This negatively affected the initial slope and the CO2 saturated photosynthetic rates under all treatments. This suggest that acclimation may have been as a result of both stomatal and biochemical limitations. All the photosynthetic pigment levels (chl_a_, chl_b_, chl_(a+b)_, and C_(x+c)_ ) increased with an increase in nitrogen supply from 4 to 6mM [N]. A 12mM [N] resulted in a significant decline in the photosynthetic pigment levels compared to a 6mM [N]. Chla remained higher than chlb under all treatments. Also, NAR was seen to increase and decrease concomitantly with the photosynthetic pigment levels. Foliar [N] was seen to decrease with an increase in nitrogen supply from 4 to 6 mM [N] under elevated [CO2] and the effects were adverse under the 4mM [N]. Under the 6mM N regime foliar [N] was positively correlated to NAR for elevated [CO2] grown plants. Similarly, E was positively correlated to foliar [N] under the same conditions. Elevated CO2 and increase in nitrogen supply had a pronounced effect on total plant height (TPH), total plant biomass (TPB), leaf area (LA), shoot and root dry weight and nitrogen use efficiency (NUE). The effects were more pronounced under a 6mM [N] as a result of high NUE. However, under 12mM [N] growth was not as expected as a result of lower NUE. Under all treatments shoot dry weight (SDW) was positively correlated to NUE. Anatomical studies revealed that total leaf and midrib thickness was significantly increased with an increase in nitrogen supply under elevated CO2 to support the larger leaf areas. There were no significant changes in the chloroplast ultrastructure as a result of the increase in nitrogen supply and CO2 enrichment. Starch grain surface area was seen to decline with an increase in nitrogen under both ambient and elevated CO2. Elevated CO2 and increase in nitrogen supply significantly increased total grain dry weight per plant by 47 and 46% respectively under 6 and 12mM [N]. In contrast, the increase was by about 21, 61 and 67% respectively under 4, 6 and 12mM [N] between the CO2 regimes.

Description: The response of wheat to soil fertilised with varying quantities of the water fern Azolla filiculoides was investigated. Experiments were conducted to differentiate between the effects of increased soil mineral status and water status. In the preliminary investigation, experiments were carried out in the greenhouse using potted wheat grown in sand with varying proportions of A. filiculoides that had been subjected tovarious pre-treatments. The pre-treatments were fresh, dry and heated A. filiculoides applied at 20%, 50% and 80% volume per 3000 ml. There were significant differences in the measured growth parameters between the plants grown in the various treatments. In addition, the grain yield of wheat plants varied with the different treatments. Results of the preliminary study showed that the addition of heated and dried A. filiculoides resulted in significantly better growth than the addition of fresh A. filiculoides in sand. For fresh biomass, grain weights, Leaf area ratio (LAR) and relative growth rate (RGR), the performance of dried A. filiculoides was as good as that of the heated A. filiculoides. Productivity of wheat in the heated treatments increased significantly with increasing proportion of A. filiculoides added to sand, while in dry treatments there were no significant increases in productivity in the preliminary study. This supported the hypothesis that A. filiculoides, a notorious water weed can be put to agricultural use under dryland conditions in poor nutrient soils. Further investigations using dried A. filiculoides in sand and topsoil showed that the use of the same amounts of the dried fern made no significant short term impact on topsoil grown winter wheat but significantly improved the productivity of wheat in sand. Results showed that the addition of dried 20% Azolla to sand improved the soil fertility to levels equalling the quality of the control topsoil, but the addition of 80% Azolla to sand led to significantly greater wheat productivity than all other treatments. The addition of dried 20% Azolla (8.14 × 10^3 kg ha^(-1)) in sand produced as much wheat biomass as the addition of the recommended NPK fertiliser (30 kg N ha^(-1)) to sand. A comparison between the topsoil and sand-grown plants showed differences in flowering time but these had no effect on the final grain and above ground biomass.

Description: The landmark inauguration of the East African Cooperation (EAC) on 14 March 1996 brought to the fore some key issues regarding regional economic integration in East Africa, particularly since it signalled the second attempt by Kenya, Uganda and Tanzania to form a regional economic bloc. The EAC's predecessor, the East African Community, had collapsed in 1977 in acrimonious circumstances. Prominent among the issues that led to the collapse of the East African Community was the perception of unequal gains from the integration scheme, with Uganda and Tanzania considering that disproportionate benefits were accruing to Kenya at their expense. With the new initiative, the question emerges as to whether the problems that caused the collapse of the Community will not beset the EAC and subject it to a similar fate. In an attempt to address this question, this study considers some of the theoretical issues relating to regional economic integration among countries at different levels of development, and attempts to provide an analysis of the new initiative of the EAC in the light of this theory and the history of the East African Community. The study also critically examines the objectives of the EAC and the integration strategy adopted by the three countries, and offers suggestions on the way forward. Among the arguments made in this thesis are that, contrary to the suggestions of orthodox static analysis, if the dynamic effects of integration are considered, then there may be important gains which may accrue to integrating states in the developing country context. It is also argued that different levels of development among integrating states need not necessarily be an impediment to economic integration. The study finds that, in spite of the enormous challenges facing the EAC, member states may be better off within the integration scheme than if they acted as individual units in a rapidly globalizing international system.

Description: A novel camphor-derived hydroxy ketal 138 has been developed as a crural auxiliary, and used to prepare a series of six carboxylic esters of increasing steric bulk. The α-benzylation of this series of esters was achieved with diastereoselectivities of 59 - 83％ d. e. and in 39 - 48％ material yield. These results compared very favourably with those obtained in earlier studies using a regioisomeric analogue as the chiral auxiliary. Computer.modelling studies of the putative enolate intermediate has provided some insight into the possible mode of electrophilic attack at the α-carbon and the roles of the ketal protecting group and the lithium cation in these asymmetric transformations. In a related investigation, based on earlier work, a camphor-derived imino lactone has provided convenient access to α-alkyl α-amino acids, the imino lactone serving as a masked glycine equivalent. Using straight chain primary alkyl iodides [RI; R = Me, Et, Pr, Bu, CH₃(CH₂)₄ and CH₃(CH₄)₅], alkylation of the potassium enolate of the camphor-derived imino lactone was effected with 54 - 89％ d.e. and in 54 - 87％ material yield. Four novel alkylated derivatives were synthesised using isopropyl iodide, sec-butyl iodide and allyl iodide, the latter reagent resulting in both the monoallylated and diallylated products. While very good diastereoselectivities were achieved (83 - 88％ d. e.) in these reactions, the material yields from reaction with the secondary alkyl iodides were low (31- 35％) due, presumably, to their decreased electrophilicity. Computer modelling studies of the enolate were carried out and support the hypothesis of endo attack by the electrophile on the enolate intermediate. These studies also indicate the possibility of coordination of the postassium cation to the endocyclic ester oxygen, thus effectively anchoring the bulky cation away from the reaction site.

Description: Following Independence in 1991 Namibia embarked on a major reform of the entire education system. The reform was perceived as a way of redressing the apartheid legacy and bringing about a democratic learner centred education for all. At the same time the reform was also seen as a prime vehicle to bring about sustainable development through incorporating relevant environmental education into various carrier subjects. One such carrier has been the subject Life Science, which is compulsory from Grade 8 to Grade 10. The Life Science Project was a joint venture between the Ministry of Education and Ibis, a Danish Development NGO, established to develop and support the implementation of Life Science in junior secondary schools. This half-thesis is an evaluation of the Life Science Project through an analysis of the central assumptions on which the Life Science curriculum is based and by investigating different stakeholders’ perceptions and understanding of the learner centred approach adopted by the curriculum. Three questions have guided this research: 1. Are there curriculum models that are more conducive for reform and change than others? 2. Do stakeholders and curriculum developers in Namibia understand the theory of social constructivism, and the systemic implications such an approach has for the education system? 3. Which approach to environmental education complements a transformative curriculum and the changes outlined in policy? From the research carried out in this half-thesis, it would appear that the Namibian education system and the Life Science curriculum suffers from what could be termed “ideological confusion”. Confusion in the sense that there are marked inconsistencies between policy and praxis, between the stated goals and aims of the reform and the curriculum designed to achieve these. This confusion is further exacerbated by various stakeholders’ different interpretations of both policy and the systemic implications the reform policy has on education. In this half-thesis I argue that embarking on an objectives driven model of curriculum cannot bring about change and transformation of the Namibian education system. I further argue that, by not having considered and implemented the necessary systemic changes to the education system, Namibia has, in fact, developed a child centred education system which is fundamentally different from a learner centred education system. Finally, I argue that environmental education, through the subject Life Science, set within an objectives driven, Child Centred Education system is inappropriate for and unable to address the need for developing an environmentally literate citizenry who are able to take informed decisions in order to address the environmental crisis and bring forth a more sustainable future.

Description: There is increasing evidence suggesting a protective role for anti-inflammatory medications in neurological disorders such as Alzheimer's disease (AD). While there has not been any direct evidence for this, a number of clinical studies indicate that those patients who have had a history of nonsteroidal anti-inflammatory use, have a lower incidence of AD. Since there is currently no evidence on the mechanism by which these agents offer possible neuroprotection, we investigated the potential neuroprotective properties of the nonsteroidal anti-inflammatory drug, ibuprofen, by examining whether this agent could reduce lipid peroxidation and superoxide radical generation. Quinolinic acid and cyanide, known neurotoxins, were used to induce lipid peroxidation and superoxide anion formation respectively, in rat brain homogenate. The results show that ibuprofen significantly (p more than 0.05) reduced quinolinic acid-induced lipid peroxidation and cyanide-induced superoxide production. The results of the present report therefore suggest a possible mechanism for the neuroprotective effect of ibuprofen.

The study attempts to draw parallels between the GEAR macro-economic policy framework and structural adjustment programmes in the South. By making use of this comparison, the study argues that the outcome of the GEAR will be no different from structural adjustment programmes in that it will fail to reduce poverty and cause government to meet the basic needs of the people. These conclusions are drawn from the fact that the GEAR policy is premised on the faith that the market is capable of redistributing income and wealth, and providing people with their basic needs.

Description: This research study was conducted in an attempt to explore the experience of multicultural communication within a South African organization. To this end employees, representing both Black and White culture, within a South African organization in the throes of transformation, were accessed. A model of managing diversity, focussing on the personal, interpersonal and organizational levels, was utilized in an attempt to uncover the nature of the experience of multi-cultural communication within Company X. A qualitative research design, and more specifically the case study method was employed in this study. Consistent with the case study approach a number of data sources were accessed. The primary data source consisted of a 3-stage interview process. Other data sources included documentary sources and company publications. By accessing multiple data sources, the researcher attempted to gain a holistic understanding of the experience of multi-cultural communication. It was found that the societal context of our post-Apartheid society exercises a profound influence on multi-cultural communication. Under Apartheid cultural separation was promoted. Diverse peoples thus have little common basis for interaction and view each other with skepticism and distrust. This exercises an effect on the personal and organizational levels of the managing diversity model. Influences at the personal level relate to the cultural paradigms of the individuals which provide the rules governing interactions and affect judgements of acceptable and unacceptable behaviours. Issues at the organizational level relate to its structures and policies which are still based on the “white is right ideology”. These issues, in turn, affect the interpersonal level of managing diversity, i.e., where the interactions occur, causing “communication short circuits” within the process of multi-cultural communication. In order to deal with failed multi-cultural communication, the individuals have developed a number of coping strategies. The results of the study indicate that both the organization and its employees share a responsibility for creating an environment that will facilitate effective multi-cultural communication.

To achieve this objective a literature study was undertaken to ascertain what knowledgeable people believed was the affects of labour legislation on SMME’s. The literature study included all relevant labour legislation promulgated by the Government since 1994 The literature study was then used to develop a questionnaire to test the degree to which SMME’s, operating in the Municipal areas of East London and King Williams Town, abided by the relevant labour legislation. The empirical results, in general, indicated a strong adherence to labour legislation. Those organisations that had not strictly adhered to labour legislation were, in most instances, not successful in securing contracts offered by Government or parastatals. The results indicated that all the role-players, namely businesses, trade unions and knowledgeable people have valid arguments both for and against labour legislation. Each group, is however, still concerned and suspicious that in one way or another, they will be placed at a disadvantage with respect to the others positions, and this places a serious strain on the South African economy.

Description: This research study addresses the problem of determining the strategies that can be used to manage conflict effectively. To achieve this objective a comprehensive literature study was performed to determine the views on conflict and various models of conflict. The study also included the reasons for and sources of conflict and the effects of conflict on an organisation. The next step was to identify the conflict management strategies that were revealed by the literature study. The appropriate conflict handling styles, how to improve organisational practices and special rules and structures were discussed as well as various suggestions from different authors on how to resolve a conflict situation. Based on the information obtained from the literature study a model was developed to serve as a guide to organisations to manage conflict effectively. Managers from a specific organisation were requested to complete questionnaires in order to determine the strategies used by their organisation to manage conflict. The questionnaire was developed in accordance with the findings from the research. The answers of the respondents were analysed and compared to the findings of the literature study. The information obtained from the literature study and from the respondents resulted in various recommendations and conclusions. The previously mentioned model that was developed was applied to the organisation, specifically addressing the pertinent issues as indicated by the respondents.

Description: South African photojournalists’ perception of digital technology’s impact on the credibility of news photographs is investigated in this study. Digital technology has the capabilities to produce “manipulated” photographs that appear realistic and credible. Credibility is dependent on a variety of factors including codes of realism and codes of production, which fit conventional codes of photographic representation. Manipulation is the act of deviating from accepted codes of photographic representation that may jeopardise the credibility of news photography. This thesis proposes a new theoretical framework that encompasses existing theories of semiotics, ideology, naturalism, realism and credibility. These theories underpin the definitions and discussion on manipulation and credibility. A descriptive survey is used which attempts to discover photojournalists’ views towards credibility. This research draws on qualitative research methods using a largely qualitative questionnaire, which generates both qualitative and quantitative data. The questions are formulated around two case studies of digitally manipulated photographs. The trends and responses in the research data are connected and discussed. The findings of this study are discussed in terms of credibility, awareness of the digital changes, the reason for the changes, the role of a caption, deletion techniques and background changes. The empirical situation is analysed in relation to the theoretical discussions and this study’s theorisation of photographic representation.
