- Description: From Christmas Eve of 1929 to the end of that year, Bulawayo was an ungovernable city marred by fights between Shona, on the one hand (perceived as a 'common enemy'), and forces that were predominantly Ndebele and groups sympathetic to them. A brilliant attempt to explain these clashes a generation ago, nevertheless falls short. This article seeks to revise the popular interpretation of this violence and re-contextualise it historically. A longer timeframe would give us an alternative view of the conflict. It also vindicates the ethnic interpretation of the violence that Phimister and van Onselen, concentrating on the then popular Marxist 'class struggle' paradigm, either minimised or failed to assess thoroughly.

- Description: Small hive beetles, Aethina tumida Murray, are parasites and scavengers of honeybee colonies, Apis mellifera L., and have become an invasive species that can cause considerable damage in its new distribution areas. An effective subspecies of Bacillus thuringiensis Berliner (=Bt) would provide an alternative to chemical control of this pest. Therefore, we tested three different Bt strains [B. thuringiensis, var. aizawai (B401®), B. thuringiensis var. kurstaki (Novodor®) and B. thuringiensis var. San Diego tenebrionis (Jackpot®)] and Perizin® (3.2% coumaphos), each applied on combs with a pollen diet fed to pairs of adult beetles. This evaluates the products for the suppression of successful small hive beetle reproduction. While none of the tested Bt strains showed a significant effect on the number of produced wandering larvae, we could confirm the efficacy of coumaphos for the control of small hive beetles. We further show that it is also efficient when applied with a lower concentration as a liquid on the combs. We suggest the continued search for efficient Bt strains naturally infesting small hive beetles in its endemic and new ranges, which may become a part of the integrated management of this pest.

- Description: A method for evaluating trap depth E, order of kinetics b and frequency factor s from a thermoluminescence (TL) glow peak has been developed. The method is based on using intensities and temperatures at any three points on the glow peak. Unlike similar techniques that provide no expression for frequency factor, the present formulation provides such an expression. The expression does not require knowledge of the temperature at which maximum intensity occurs, a parameter not usually known accurately from experimental glow peak data. For the method, it is found that use of points in the ascending part of the glow peak where the intensities are less than 10% maximum intensity gives parameter values closest to the true ones. Possible reasons for getting less accurate results when points are taken beyond this region are discussed. Values of the activation energy calculated using the present technique were always close to the true value. However, the frequency factor only approaches the true value as the dose given to the sample approaches saturation. When the three data points are selected in the initial-rise region, the equation for evaluating E in the method described in this paper becomes a two-point version of the initial-rise method. The advantage of the present technique over the initial-rise method is that it also gives b and hence s. The method is used to analyse the TL glow curve of a gamma-irradiated sample from Ijero-Ekiti, Nigeria.

- Description: Tablets manufactured in-house were compared to a marketed sustained-release product of verapamil to investigate the rate of hydration, erosion, and drug-release mechanism by measuring the wet and subsequent dry weights of the products. Swelling and erosion rates depended on the polymer and granulating fluid used, which ultimately pointed to their permeability characteristics. Erosion rate of the marketed product was highest, which suggests that the gel layer that formed around these tablets was weak as opposed to the robust and resistant layers of test products. Anomalous and near zero-order transport mechanisms were dominant in tests and commercial product, respectively.

- Description: This study is a contribution to the literature on South Africa's foreign policy since 2000-2004. It provides a theoretical framework within which South Africa's foreign policy should be understood. It attempts to explain the contradictions that have been apparent in South Africa's foreign policy by looking at the constraints inherent in South Africa's position as an emerging middle power. It argues that South Africa's pluralist inclinations are constrained by Africa's evolving multilateral forums and that South Africa's preference for such undermines the realization and achievement of her foreign policy principles and goals. It also argues that as a realist middle power, South Africa is constrained the ambivalence shown by the region towards her exercising leadership in the region. This is due to South Africa's history of destruction in Southern Africa in the 1980's. South Africa's quiet diplomacy towards Zimbabwe provides the focal point for the study. The study argues that it is not the case that South Africa is not concerned with human rights abuses in Zimbabwe. Instead, this concern has been expressed in ways that do not tarnish South Africa's own image in Africa. This has been done by engaging Zimbabweans through multilateral forums. This study concludes that this strategy failed to bring about resolution to the Zimbabwean crisis.

- Description: Intertidal size-frequency distributions and densities for Haliotis midae and Turbo sarmaticus were examined at 10 sites experiencing varying pressure of human exploitation along the southern section of the Eastern Cape coast, South Africa. Target species' densities and maximum sizes were related both to the numbers of collectors on the shore and to indirect indicators of exploitation such as number of households in the vicinity and distance to the nearest beach access point. For both species, there was variation in density (P < 0.05) and size (P < 0.05) among sites, with densities ranging between 0.03-2.23 m^(-2) and 0.07-4.93 m^(-2) for H. midae and T. sarmaticus, respectively. Maximum sizes ranged between 49.4-153.5 mm (H. midae) and 28.3-104.4 mm (T. sarmaticus) shell length. Population parameters such as mean maximum size and total density were significantly negatively related to exploitation indicators for both species. In addition, densities of sexually mature and legal-size individuals of T. sarmaticus were significantly negatively related to the number of households. However, only for H. midae were densities of subadults significantly negatively related to the number of collectors, suggesting that reproduction of abalone may be suppressed at the most exploited sites. Exploitation of T. sarmaticus tends to be localized near population centres, whereas H. midae is collected over a larger range of sites. Overall, T. sarmaticus is less affected by exploitation than H. midae.

- Description: In the current business climate, performance is increasingly determined by how flexibly and effectively companies can utilize their human resources and this in tum, is influenced by employee morale. Morale refers to a state of psychosomatic health marked by an energetic, decisive resolution to achieve a given goal. When morale is low, employees may do what is required but do not have the energy to 'go the extra mile'. The importance of maintaining high morale is thus evident. The following project involved a study of morale in Cadbury's Port Elizabeth plant. Cadbury management was concerned about low morale following a recent merger with Bromor Foods. They thus wanted to assess: the state of current morale; any factors that may be influencing it; indicators of low morale (so that it may be monitored in the future) and finally, ways of addressing any existing morale issues. In order to achieve these aims, the researcher conducted interviews with various people to explore morale issues from employees' perspectives. She then sought confirmation for these views at the organizational level through the use of a survey. Statistical and thematic analyses showed morale to be low for middle managers and revealed a variety of indicators and influencing factors, as well as suggestions for addressing them. Despite the need to boost the sample size with convenience sampling, and thus, reduced representivity, the research was successful in answering the research aims.

- Description: The population structure and feeding dynamics of the hyperiid amphipod, Themisto gaudichaudii, was investigated during two cruises of the South African National Antarctic Programme conducted in the Indian sector of the Polar Frontal Zone during austral autumn (April) 2004 and 2005. During the 2004 cruise the frontal features that delimit the PFZ converged to form a single distinctive feature. In 2005, the research cruise was conducted in the vicinity of a cold-core eddy which was spawned from the Antarctic Polar Front. Total mesozooplankton abundance and biomass during the 2004 study ranged from 55.19 to 860.57 ind. m⁻³, and from 2.60 to 38.42 mg dwt m⁻³, respectively. In 2005 the abundance and biomass ranged from 23.1 to 2160.64 ind. m⁻³, and from 0.76 to 35.16 mg dwt m⁻³, respectively. The mesozooplankton community was numerically dominated by copepods, pteropods, and ostracods during both surveys. The abundance and biomass of Themisto gaudichaudii in the region of investigation was < 0.2 ind. m⁻³ (range 0.01 to 0.15 ind. m⁻³) and < 0.06 mg dwt m⁻³ (range 0.02 to 0.06 mg dwt m⁻³) during 2004, while in 2005 the abundance and biomass of the amphipod ranged from < 0.01 to 0.2 ind. m⁻³ and < 0.01 to 0.04 mg dwt m⁻³, respectively. These values correspond to < 1% of the total mesozooplankton abundance and biomass during both surveys. T. gaudichaudii exhibited no significant spatial patterns in abundance, biomass and total length during both 2004 and 2005 (p > 0.05 in all cases). A key feature of the two investigations was the virtual absence of juveniles (total length < 15 mm) among the amphipod population, supporting the suggestion that they exhibit strong seasonal patterns in reproduction. Gut content analysis during both years indicated that for both the male and female amphipods’, copepods were the most prevalent prey species found in stomachs, followed by chaetognaths and pteropods. Results of electivity studies indicate that T. gaudichaudii is an opportunistic predator, generally feeding on the most abundant mesozooplankton prey. Results of in vitro incubations indicated that the total daily feeding rate of T. gaudichaudii during 2004 ranged from 11.45 to 20.90 ind. m⁻³ d⁻¹, which corresponds to between 0.12 and 1.64% of the total mesozooplankton standing stock. In 2005, the feeding rate ranged between 0.1 and 1.73% of the total mesozooplankton standing stock. The low predation impact of T. gaudichaudii during this study can be related to their low abundances and high interannual variability throughout the region of investigation.

- Description: The development of small (<300 km²), private game reserves has become a trend, not only in the Eastern Cape Province, but also elsewhere in South Africa as a result of a shift in land use practise from agriculture to ecotourism. The resultant re-introduction of elephants to many of these reserves has lead to management concerns because of the limited research on small reserves regarding their impact on the vegetation. In this study I assessed the space use, habitat selection, diet and impact of two elephant populations on the vegetation in the Eastern Cape Province between February 2004 and March 2005. Home range sizes were calculated using the kernel utilization distribution method. Home range sizes for elephants on Kwandwe were significantly larger during summer than winter (p<0.05). There was no significant difference between the home range sizes of the herds and males within a season and during summer the elephants utilized about 75 % of the reserve and only 54 % during winter. On Shamwari, the herd utilized about 92 % of the reserve during summer and 83 % during winter; while the males utilized 76 % of the reserve. Core areas for both elephant populations shrank from summer to winter and were concentrated around the permanent water sources on each reserve. Habitat selection was assessed using χ² tests and Bonferroni confidence intervals. On Kwandwe, there was a significant difference between observed and expected use of vegetation types (p<0.05) and karroid shrubland was strongly avoided by both herds during summer and winter. The preferred vegetation types of the males ranged from relatively open (short euphorbia thicket, bushclump karroid thicket and karroid shrubland) to completely open (old lands). On Shamwari, subtropical thicket, bontveld and montane grassland were avoided; while primary and secondary acacia thicket, riverine thicket and cultivated lands were preferred. The predominant vegetation type in the home ranges of herds on Kwandwe and Shamwari was subtropical thicket. The diet was assessed by direct observations over two seasons and dietary preferences were calculated. There was a significant difference in the frequency of occurrence of plants in the diet on the two reserves (p<0.05) and no significant effect of time of day or season (p>0.05). Seventeen woody plant species were utilized on Kwandwe and 23 species were utilized on Shamwari. Grass constituted a significantly greater percentage of the diet in summer than winter (p<0.05). Elephants on Kwandwe showed a selective preference for Ozoroa mucronata, Pappea capensis and Acacia karroo; while on Shamwari, A. karroo was selected. Transects were conducted in two different vegetation types on each reserve so as to assess the impact of elephant on the vegetation and damage scores were then calculated from these data. There was no significant effect of vegetation type or elephant density on mean damage scores in Kwandwe (p>0.05). Five hundred and seventy-eight plants were assessed in the subtropical thicket vegetation type and 225 plants were assessed in the savanna-type vegetation, with more than half the trees showing low levels of damage that could not only be attributed to elephants. Mean damage was highest for Portulacaria afra and Pappea capensis in subtropical thicket and for Rhus spp. in the savanna-type vegetation. On Shamwari, 408 plants were assessed in subtropical thicket and 215 in the savanna-type vegetation, with more than 70 % of trees showing low levels of damage. There was a significant effect of plant species and elephant density on the mean damage scores in subtropical thicket, with Aloe ferox showing more damage than the other plant species (p<0.01). In the savanna-type vegetation, A. karroo was the most severely damaged. Overall, damage was greater in the thicket vegetation type compared to the more open vegetation type on both reserves.

- Description: Using cointegration and error correction techniques, as well as impulse response analysis, the study examined the extent of interest rates pass-through to measure the degree of financial integration amongst the SACU countries. The results confirm the dominant role of South Africa in the Union and show that there exists a hierarchy of integration of the financial systems of each member state with that of South Africa, with Namibia at the top, followed by Swaziland, then Lesotho, with Botswana at the bottom. The results further suggest that the prevailing integration between the financial systems is mainly as a result of policy convergence, rather than market convergence, which suggest limited arbitrage opportunities between the countries. The lack of arbitrage opportunities is attributed to poor institutional developments and limited investment opportunities in the BLNS countries when compared to South Africa.

- Description: Financial reforms were a major component of structural adjustment programs deemed necessary for developing countries in the mid 1980s. These were not only meant to improve the sector, but would ultimately enhance economic growth and help in poverty alleviation. At the top of these reforms was financial liberalisation. Kenya, like many other sub-Saharan African countries, undertook financial liberalisation in 1991, one of the measures was decontrolling interest rates. With market driven interest rates in place it was assumed that there would be increased efficiency in bank lending, as well as growth in credit availability as deposits increased. A key indicator of this improved intermediation process would be a narrowing interest rates spread, that is, the margin between the deposit and lending rate. Paradoxically, however, the expected benefits of these reforms did not accrue to Kenya's banking sector. This study focuses on financial reforms and the spread of interest rates in Kenya's banking sector. Using a trend analysis, spanning the period before and after liberalisation, interest rates spread are shown to have escalated dramatically upwards after liberalisation. An analysis of three macroeconomic variables, namely, the exchange rate, inflation rate and economic growth offer little, or inconclusive evidence, that they were the main causes of the wide interest rate spread. In fact, the spread is closely linked to institutional/structural factors such as non-competitiveness in the banking sector, imprudent lending practices and poor and/or inadequate banking supervision. Policies for improving the institutional infrastructure and thus moderating the spreads are highlighted.

- Description: This study presents results from stomach content analysis of 123 largemouth bass, Micropterus salmoides, sampled at the mouth of the fishway leading into a 3 m high weir at the tidal limit of the Kowie River, Eastern Cape Province (33°32‘39“S, 26°46‘ 52.3“E). Stomach contents from small (120–240 mm fork length, FL) and large (250–440mm FL) fish were analysed separately. Fish were the dominant prey item in small bass, followed by terrestrial insects and Potamonautes sp. In large bass, Potamonautes sp. dominated the stomach contents, while fish were less dominant and other prey items were considered incidental. Estuarine fish species, Monodactylus falciformis, and two species of the family Mugilidae, Mugil cephalus and Myxus capensis, were the most common fish prey in both size classes of M. salmoides. These results are the first evidence of the alien M. salmoides preying on these three indigenous estuarine species during their migration into fresh water.

The demersal habitat in depths of 150–400 m at the volcanic island of Ngazidja is low in fish diversity and biomass, compared with the shallow-water coral reef habitat of Ngazidja or the deep demersal habitats of other localities in the Indo-Pacific region. The resident deep demersal fish fauna at Ngazidja is dominated by the coelacanth, an ancient predator that is specially adapted for this low-energy environment. Other large fish predators are scarce in this environment, because of the heavy fishing pressure from local fishermen. Eighty-nine fish taxa (including 65 recognizable species) were recorded from videotapes, photographs, visual observations, fishermen’s catches and ancillary attempts to sample the fish fauna with baited fish traps, gill nets, and hook and line. Although no coelacanth feeding events were seen, seven fish species are known from coelacanth stomach contents, and 64 other fish species in this habitat are considered potential prey of this dominant predator.

- Description: This thesis defends an ontological and epistemological account of Michel Foucault's post-structuralist philosophy, to argue that political philosophy needs to take into account the historical and political contingency of subjectivity and discourse. I show that by addressing the historical and political contingency of knowledge, Foucault's work overcomes the flaw of foundational epistemology in political philosophy, which treats true discourse as universal and disinterested. In doing so I hope to have to refuted the mainly positivistic and humanist schools of thought that lay claim to universal and foundationalist notions, by demonstrating the extent to which their misgivings about Foucault's work are informed by and founded upon an unjustified a-historicism. The thesis is composed of three chapters, the first of which deals with an ontology of the subject, the second, with an ontology of social relations, and the last with epistemology. In each chapter I use dialectical analysis to reveal how interests necessarily mediate subjectivity, social relations, and knowledge. The first two chapters defend Foucault's conception of power, by way of an analysis of the relations between Foucault's work and Sartre's existential phenomenology. I show how both Foucault and Sartre successfully address the problem of historicism for political philosophy with their respective conceptions of human freedom. The final chapter defends Foucault's conception of the relations between power and discourse, to show how it overcomes the a-historicism of universal, foundational epistemology. These three chapters demonstrate the importance of accounting for historicism in political philosophy. Claims to universal interest, because knowledge is conditioned by conflicts of interest, often mask political domination. It is important, then, to remember, in political philosophy, that knowledge is evaluative and interested, reflecting historically and politically mediated evaluations. One should be suspicious of ' natural facts' , used to justify actions or beliefs, thereby masking the choices that inform them. I have used the work of Michel Foucault to motivate this claim.
