Abstract: In order to analyse the strategic issues with regard to the South African Platinum Group of Metals (PGM) industry, a risk analysis and an assessment of the competitiveness of the industry were conducted. The analysis of risk related to market conditions indicates a relatively low risk rating driven by increased demand for jewellery and autocatalysts, while the industry is exposed to moderate risk for raw materials and supporting services, which is expected to remain moderate in future. Overall, the current risk for production factors was found to be moderate and is expected to remain moderate over the medium term. The results of industry risk analysis indicate that the PGM industry is currently exposed to moderate risk. Applying Porter’s diamond model (Porter, 1990), the research found that the South Africa’s PGM industry has a very strong platform and is expected to become more competitive in future, although increased cooperation will still be evident. The competitiveness of South African producers is expected to increase over the medium term, since most of the expansion will come on stream in the near future. The paper also discusses the development potential of South Africa in line with the exploitation of PGM. URI: http://hdl.handle.net/10311/295 Files in this item: 1

Abstract: This paper explores the implementation of public sector performance reforms in Botswana magistrate courts to improve service delivery. The authors argue that it is imperative for management to consider the possibility of the unintended outcomes in public sector reforms something that is normally ignored when introducing change. Critical realist philosophy has been adopted as a guiding paradigm for this study. The main contention is that the social world exists independently of the researcher. In this study realist philosophy was used together with the case study methodology to give context. In the courts performance management was supposed to help improve service delivery by reducing court congestion, legal costs, and delays. However, the findings suggest that this has not been the case because of gaming and manipulation of performance measures. A principal constraint in writing this paper was the absence of relevant literature in Botswana. Data was sourced from one organisation used as a case study. Problems like the backlogs of cases and delays affect both the fairness and efficiency of the judicial system. Efficiency has to take account of other factors. Developing performance management systems that incorporate measurement and evaluation in the public sector continues to be a key challenge. Both the positive and negative effects of PMS must be embraced. URI: http://hdl.handle.net/10311/1083 Files in this item: 1

Abstract: Pn arrivals from mining-induced earthquakes on the edge of the Witwatersrand basin show that the P wavespeeds in the uppermost mantle are almost constant throughout most of the Kaapvaal craton. The presence of only small wavespeed variations allows the use of a simple method of estimating crustal thicknesses below the stations of the Kaapvaal broad-band network using Pn times that has been compared with results from receiver functions. One thousand three hundred thirty-seven Pn arrivals were used to derive crustal thicknesses at 46 stations on the Kaapvaal craton. The average crustal thicknesses for 19 centrally located stations on each of the northern and southern regions of the craton that yielded well-constrained thicknesses were 50.52 ± 0.88 km and 38.07 ± 0.85 km, respectively. In contrast, the corresponding average thicknesses determined from receiver functions were 43.58 ± 0.57 km and 37.58 ± 0.70 km, respectively. The systematically lower values for receiver functions in the northern part of the Kaapvaal craton that was affected by the Bushveld magmatism at 2.05 Ga, suggest that the receiver functions do not enable the petrological crust mantle boundary to be reliably resolved due to variations in composition and metamorphic grade in a mafic lower crust. The Pn times also suggest pervasive azimuthal anisotropy with maximum wavespeeds of about 8.40 km/s at azimuths of about 15° and 217° in the northern and southern regions of the craton, respectively, and minimum wavespeeds of about 8.25 km/s.

Abstract: This article considers Lesotho’s political history and culture, a political history characterised by rebellious chiefs who had rejected Christianity and who were heavily armed and fought numerous wars against their black and white neighbours. Its argument is that the state’s dysfunctionality in small Lesotho is a result of a political culture and history of armed resistance, producing rebellious political elites who feuded between themselves, against the colonial establishment and against the postcolonial government. It was also a political culture that rejected Christianity, accepted old leaders to die in office and encouraged factionalism. The political parties that emerged from such a political culture were traditionally oriented, radical, dominated by old leaders and were factionalised. Such a society was not easily open to renewal through fresh leaders and borrowed ideas. The article suggests that Lesotho need to come to terms with its political history and to come up with a cultural re-orientation away from traditionalism, rebellion and factionalism.

Abstract: This chapter discusses the national integrity system of political parties. In assessing the viability and integrity of political parties, the purpose of their existence needs to be established and analysed. The building and institutionalisation of political parties is a basic prerequisite for deepening and consolidating democracy. However, the organisational structures and the resources at the disposal of political parties influence their effectiveness. In addition, as entities that make national laws within the framework of parliamentary democracy, political parties must conduct themselves in an open and ethical manner. This chapter will assess their integrity, the handling of conflict of interest, and their perception regarding rules and disclosure. URI: http://hdl.handle.net/10311/635 Files in this item: 1

Abstract: The study set out to determine the weathering and dissolution of metal hosting minerals at Dorowa for purposes of deducing pollution potential to the nearby Save River. Phosphate rock is mined at Dorowa for the production of phosphate fertilizer. The major minerals found in the ring complex are feldspars, pyroxenes, apatite, magnetite and calcite. Chemical analysis established that the rocks are associated with metals that include copper, lead, zinc, cobalt, nickel, tin and cadmium. Among the many minerals present apatite and calcite host metals more than the other minerals due to their crystal structure. This study investigated the weathering and dissolution of these two minerals. Both apatite and calcite dissolve in natural environmental conditions prevalent at Dorowa. From the analysis the study concludes that the potential availability of metals trapped in the calcite and apatite structures is high. The understanding of weathering and dissolution of metal hosting minerals is important in predicting quality of water around the study area, because most villagers use the Save River as their primary drinking water source.

Abstract: Based on government and other relevant documentation, this paper explores the conceptual linkage between population, development, and waste management in Botswana and the implications of this relationship for global climate change. Population is increasing, albeit at a decreasing rate. Spatially, the population is becoming more and more concentrated as the rates and level of urbanization increase. Economic growth has remained consistently high. The combined effect of population dynamics and economic development are having a noticeable imprint on the environment in the form of increased waste generation. Poor waste management poses a real threat to environmental sustainability in general and climate change in particular because of inadequate technology, weak institutional mechanisms to enforce regulations, and low levels of sensitization among the public to deal with the problem. Mitigation measures are suggested to minimize the negative effects of waste management on climate change. URI: http://hdl.handle.net/10311/478 Files in this item: 1

Abstract: Background In Botswana, an estimated 24% of adults ages 15–49 years are infected with HIV. While alcohol use is strongly associated with HIV infection in Africa, few population-based studies have characterized the association of alcohol use with specific high-risk sexual behaviors. Methods and Findings We conducted a cross-sectional, population-based study of 1,268 adults from five districts in Botswana using a stratified two-stage probability sample design. Multivariate logistic regression was used to assess correlates of heavy alcohol consumption (>14 drinks/week for women, and >21 drinks/week for men) as a dependent variable. We also assessed gender-specific associations between alcohol use as a primary independent variable (categorized as none, moderate, problem and heavy drinking) and several risky sex outcomes including: (a) having unprotected sex with a nonmonogamous partner; (b) having multiple sexual partners; and (c) paying for or selling sex in exchange for money or other resources. Criteria for heavy drinking were met by 31% of men and 17% of women. Adjusted correlates of heavy alcohol use included male gender, intergenerational relationships (age ≥gap 10 y), higher education, and living with a sexual partner. Among men, heavy alcohol use was associated with higher odds of all risky sex outcomes examined, including unprotected sex (AOR = 3.48; 95% confidence interval [CI], 1.65 to 7.32), multiple partners (AOR = 3.08; 95% CI, 1.95 to 4.87), and paying for sex (AOR = 3.65; 95% CI, 2.58 to 12.37). Similarly, among women, heavy alcohol consumption was associated with higher odds of unprotected sex (AOR = 3.28; 95% CI, 1.71 to 6.28), multiple partners (AOR = 3.05; 95% CI, 1.83 to 5.07), and selling sex (AOR = 8.50; 95% CI, 3.41 to 21.18). A dose-response relationship was seen between alcohol use and risky sexual behaviors, with moderate drinkers at lower risk than both problem and heavy drinkers. Conclusions Alcohol use is associated with multiple risks for HIV transmission among both men and women. The findings of this study underscore the need to integrate alcohol abuse and HIV prevention efforts in Botswana and elsewhere. URI: http://hdl.handle.net/10311/591 Files in this item: 1

Abstract: The purpose of the present investigation was to examine the effects of a repeated eccentric exercise on position sense and muscle reaction angle. Fourteen healthy women underwent an isokinetic exercise session on their knee flexors, which was repeated after 4 weeks. Muscle damage indices, position sense and joint reaction angle of the knee were examined before, immediately after, as well as at 1,2,3,4 and 7 days after exercise. The second exercise bout induced significantly lesser effects in all muscle damage indices as well as lesser disturbances in position sense and reaction angle when compared to the first one. The main finding of this study is that position sense and joint reaction angle to release of the lower limbs may adapt in response to a repeated bout of eccentric exercise, leading to less disturbances in position sense and reaction angle after the second bout of exercise.

Abstract: The growing body of literature authored by women in Africa and the African Diaspora over the past four decades has been accompanied by vigorous debates out of which has evolved a body of theories pertaining to African Feminism(s). Theoretical models such as ‘Third World Feminism’, ‘African Feminism’, ‘Womanism’, ‘Stiwanism’, ‘Afrikana Womanism’ and ‘Nego-feminism’, amongst others, have responded to the anomalies exhibited by mainstream feminism, particularly its inability to address the cultural specificities out of which ‘other’ feminisms are theorised. The focus of this article has arisen out of the realisation that while such theories are invaluable to the development of feminist discourse, they have tended to focus predominantly on the politics of naming associated with the term ‘feminism’.

Abstract: For the last two decades, Botswana has had a reputation as a ‘country of immigration’, based on the large-scale import of skilled expatriates from Africa, Asia, and the West. This policy has been accompanied by a general acceptance, and even openness, on the part of Batswana towards non-citizens. In the late 1990s, however, these attitudes began to change, with intolerance towards non-citizens growing in a country where it was unknown only a few years earlier. (Crush 2003:1-2) The underlying reason for the growth in intolerance seems to be related to actual changes in immigration patterns in Botswana. The economic and political problems in Zimbabwe in particular have led to a significant increase in unauthorised migration to and through Botswana. The Botswana authorities have become considerably more active in arresting and deporting unauthorised migrants. Further adding to the visibility of the issue, the media and politicians have begun to identify the presence of ‘illegal immigrants’ as a problem.

Abstract: Economic growth is usually recognized as a vital factor in poverty eradication. Thus, with the excellent performance of Botswana's economy over the years, observers had hoped that poverty in the country would decline dramatically. However this has not been the case. Mass poverty in Botswana has led to increasing concems with policies and associated development efforts that focus on, or have aspects aimed at, poverty eradication. The government of Botswana has implemented social polices to assist vulnerable groups such as the destitute, the elderly and remote area dwellers (RADs). Despite these efforts, many individuals and households continue to experience poverty. This paper discusses poverty eradication within the context of Vision 2016, which is aimed at prosperity for all Batswana. URI: http://hdl.handle.net/10311/894 Files in this item: 1

Abstract: Although Botswana is clearly one of the richest countries with one of the most vibrant economies in Africa, available statistical evidence suggests that the problem of poverty has recently caused a lot of concern in the country. Numerous attempts already made to deal with the problem have not yielded encouraging results, as the incidence of poverty continues to persist. Drawing from the experiences of three other African countries, this paper recommends a strategy based on strengthening small and medium enterprises (SMEs)for poverty reduction in Botswana. After discussing the constraints facing the SMEs in the country, the paper presents a set of six recommendations designed to ameliorate, if not eliminate, these constraints, thereby strengthening the employment and income generating capacities of the SMEs and consequently reducing poverty in the country.

Abstract: Thefocus of this paper is on the role of outsider activists who are supporting a group of Basarwa resisting relocation from the Central Kalahari Game Reserve (CKGR) in Botswana. The role of non Basarwa activists is problematized in order to unravel some of the complexities surrounding advocacy, especially its bearing on the relative power of the 'supported'. The paper argues that in the case of Basarwa who are currently being forcibly relocated by the Botswana Government out of the CKGR, oftentimes the voice of 'outsiders' who eloquently expose the human rights abuse of their subjects becomes more dominant than the local voices. This is especially so when the advocacy is done using Information and Communication Technologies (lCTs). URI: http://hdl.handle.net/10311/907 Files in this item: 1

Abstract: One of the critical elements that determine the competitiveness of nations is the population density of, and quality of its engineers. This view has been corroborated by researchers such as Biluch (1989), Garelli et al (1997), and Gharajedaghi (1986). Unfortunately most African countries are not performing well on this front. Engineering education institutions, entrusted with the task of improving the measures, find themselves in the uneviable position of attempting to operate in environments in which governments are continuously reducing funding to education in general. The objective of this paper is to develop conceptual models which can aid engineering institution overcome the financial constraints, increase throughput of engineers, and improve the quality of engineering education. The model is based on the cybernetics paradigm and is validated through structural and multiplicative corroboration. URI: http://hdl.handle.net/10311/825 Files in this item: 1

Abstract: Using a corpus of about 200 letters written during the time that Botswana was a British protectorate (1885–1966) by and to the British administrators on one hand, and letters written to and by Batswana (natives of Botswana) on the other hand, this paper explores the main differences and similarities between letter writing by Batswana and by the British. The study found that in the letters written by the British there is directness in presenting the point, very little stylistic ornamentation, and emphasis on information or content of the letters. The letters are more formal with shorter salutations and signatures. Letters written by Batswana on the other hand reveal that the conventions of letter writing in Setswana require greetings and an employment of address forms that convey respect and politeness in the Setswana culture. Letters written by Botswana thus have longer introductions and salutations which involve greetings and best wishes. URI: http://hdl.handle.net/10311/731 Files in this item: 1

Abstract: The paper aims to compare predictions by different methods of analysis of the lateral load capacity of unreinforced masonry walls, and to determine whether a relationship can be drawn between theory and experiments. Several analysis methods were employed to predict failure loads of a number of wall panels, and the results were compared with test values. It is concluded that boundary conditions play a major role in the accuracy of analytical methods. When the boundary conditions assumed in the analysis most nearly match the real conditions of the test panels, predictions are most accurate. The authors conclude that finding a rational analysis and design procedure for laterally loaded masonry walls is possible. URI: http://hdl.handle.net/10311/890 Files in this item: 1
