Abstract: The Neoarchaean Tati granite–greenstone terrane occurs within the southwestern part of the Zimbabwe craton in NE Botswana. It comprises 10 intrusive bodies forming part of three distinct plutonic suites: (1) an earlier TTG suite dominated by tonalites, trondhjemites, Na-granites distributed into high-Al (Group 1) and low-Al (Group 2) TTG sub-suite rocks; (2) a Sanukitoid suite including gabbros and Mg-diorites; and (3) a younger high-K granite suite displaying I-type, calc-alkaline affinities. The Group 1 TTG sub-suite rocks are marked by high Sr/Y values and strongly fractionated chondrite-normalized rare earth element (REE) patterns, with no Eu anomaly. The Group 2 TTG sub-suite displays higher LREE contents, negative Eu anomaly and small to no fractionation of HREE. The primordial mantle-normalized patterns of the Francistown TTGs are marked by negative Nb–Ti anomalies. The geochemical characteristics of the TTG rocks are consistent with features of silicate melts from partial melting of flat subducting slabs for the Group 1 sub-suite and partial melting of arc mafic magmas underplated in the lower crust for the Group 2 sub-suite. The gabbros and high-Mg diorites of the Sanukitoid suite are marked by Mg#>0.5, high Al2O3 (>>16%), low TiO2 ( < 0.6%) and variable enrichment of HFSE and LILE. Their chondrite-normalized REE patterns are flat in gabbros and mildly to substantially fractionated in high-Mg diorites, with minor negative or positive Eu anomalies. The primordial mantle-normalized diagrams display negative Nb–Ti (and Zr in gabbros) anomalies. Variable but high Sr/Y, Sr/Ce, La/Nb, Th/Ta and Cs/La and low Ce/Pb ratios mark the Sanukitoid suite rocks. These geochemical features are consistent with melting of a sub-arc heterogeneously metasomatised mantle wedge source predominantly enriched by earlier TTG melts and fluids from dehydration of a subducting slab. Melting of the mantle wedge is consistent with a steeper subduction system. The late to post-kinematic high-K granite suite includes I-type calc-alkaline rocks generated through crustal partial melting of earlier TTG material. The Neoarchaean tectonic evolution of the Zimbabwe craton is shown to mark a broad continental magmatic arc (and related accretionary thrusts and sedimentary basins) linked to a subduction zone, which operated within the Limpopo– Shashe belt atf2.8–2.65 Ga. The detachment of the subducting slab led to the uprise of a hotter mantle section as the source of heat inducing crustal partial melting of juvenile TTG material to produce the high-K granite suite.

Abstract: This article is about the way people of Tswana origin related with non Tswana speaking people and how they referred to them. It talks about how some of the non Tswana speaking people especially the Whites or Makgowa came into being as seen by the Tswana and other inhabitants of Southern Africa. The article also talks about trade, Traders and Travellers among the Tswana, other Africans in Southern Africa and the Whites (Makgowa,the Boers (Maburu), the Portuguese in Southern Africa. The barrier between "us" and "them" (or in postmodern-speak, "the other") in Sotho- Tswana language is said to be most clearly demarcated by the mo-! ba- (singular! plural) distinction in noun prefixes given to "us" people and the le-! ma- prefixes given to "them" people. This being a mirror image of Nguni usage, where "us" are ama- and "they" are abe-. URI: http://hdl.handle.net/10311/1102 Files in this item: 1

Abstract: Statistics show that at present there are more gospel musicians in Zimbabwe than secular musicians. Consequently this paradigm shift has not gone unquestioned. People have asked what the mission of these gospel musicians is. Are they true ministers of the Word, or lovers of money clothed in ministerial garments? This article attempts to analyse the mission of gospel musicians. Since the gospel musicians we are discussing and those who criticise them are mainly Christians whose views are shaped by their understanding of the Bible, my analysis will be from a biblical (i.e. Christian) perspective. Data from informal interviews with some Zimbabwean gospel musicians and fans, as well as songs from CDs and video cassettes were used in the analysis. The article is divided into four sections: The first defines and gives a brief history of gospel music in Zimbabwe. It is followed by a presentation of the criticisms brought against gospel musicians. The third section is a critical review of the mission of the musicians: Are they making money or spreading the gospel, or they are making money and spreading the gospel? The fourth section attempts a theology of gospel music before a conclusion wraps up the article. URI: http://hdl.handle.net/10311/1092 Files in this item: 1

Abstract: Purpose - The purpose of this paper is to investigate whether expatriate workers in Botswana are a labour aristocracy. Design/methodology/approach - This is a case study based on documentary research methods. Findings - The evidence presented supports the case for the existence of a foreign labour aristicracy in Botswana. The labour aristocracy thesis has come under attack for describing the better-paid workers aslabour aristocrats and for its failure to take cognizance of the heterogeneity of the working class. Although it appears that the thesis has now been relegated to the periphery of labour studies debates, evidence from Botswana of a two tier wage structure, one for citizens and another for "expatriates", resonates with the basic tenets of the labour aristocracy thesis. Research limitations/implications - There is a need to revisit the debate and for more case studies from different Third World countries. Practical implications - The paper highlights the difficulties faced by citizen employees in Botswana in seeking to improve their material conditions. Originality/value - This paper reveals a linkage between a wages policy and the notion of national development in a specific society. URI: http://hdl.handle.net/10311/892 Files in this item: 1

Abstract: The need for productivity increases in the agricultural sector in Botswana in order to help improve farm incomes, especially incomes of resource-poor farmers, has been an important concern in the poverty alleviation effort in the country. Appropriate technology generation and dissemination in both the crop and livestock production sub-sectors hold the promise of improving agricultural productivity. This paper discusses how the farming systems approach (FSA) can contribute to the successful generation and dissemination of appropriate agricultural technologies. The paper concludes that prerequisites for success in the technology generation and dissemination process include the political will to do so, adequate funding, the provision of relevant technical personnel and the willing participation offarmers in the technology generation process.

Abstract: Male violence against women has become commonplace in contemporary Botswana. Analyses of gender-based violence in Botswana indicate that men are acting out their dominance through acts of violence. This dominance is created and reinforced by patriarchal beliefs and practics. The discussions are characterised by notions of female victimhood and universal male dominance. This paper contextualises male violence agaisnt women by examining the role played by economic and social change in the shaping of gender identities and relations. I show that while contemporary forms of male dominance have resulted from their privileged access over time to resources such as wages and property, men also face uncertainties of unemployment and reduced social status. I also show that rather than assuming the role of passive victims, women have developed, and continue to develop, contradictory survival strategies such as cohabitation and sexual relations that not only reinforce notions of male dominance but sometimes also challenge power relations and render some men victims.

Abstract: In May 2004, an allegation that indomie noodles were causing illness and death started making the rounds and driving fear into the minds of loyal consumers in Nigeria. After thorough investigations, NAFDAC gave De-United Foods, makers of indomie noodles, a clean bill of health. The study sought, from the purview of fear appeal postulation, to determine the attitude of consumers to the noodles during and after the crisis. Findings indicate that even though the company had made appreciable progress in winning back consumers' confidence it has to do more to regain lost market share. The study recommends using adverts featuring health professionals and credible persons who would be depicted as endorsing the product, thus serving as reassurances to consumers that are still holding out.

Abstract: Since independence, the economy of Botswana has been undergoing a rapid transition from one in which the majority of the people depend on traditional agriculture and pastoralism to one in which formal sector employment predominates. This is partly reflected by rapid increase in vehicle population. Because of these changes,the country started to experience environmental problems. Unfortunately from the time of independence until late eighties, the level of environmental awareness in the country was very low, and therefore waste minimisation and reduction of environmental impact procedures were never in place.To date, many organizations in the country still seem not to be committed to reducing and disposing their wastes in environmentally friendly manner. The need to reconcile development with environmental concern, thus sustainable development, is vital. For the country to achieve that, an introduction of an environmental impact assessment in Botswana is essential, and thus, the main thrust of the current investigation is to determine the level of concern about environmental problems posed by waste engine oil in various organizations in the country. Management of various organizations were interviewed on their methods of waste of engine oil disposal. It was found that the disposal of waste engine oil by many organizations is resulting in serious environmental problems. URI: http://hdl.handle.net/10311/675 Files in this item: 1

Abstract: Although the discovery of diamond has propelled Botswana from one of the poorest countries in 1966 to its current stage of development as a middle-income country, the country still faces the problems of economic diversification, employment creation, income generation and distribution, and poverty alleviation. Government and non-governmental organizations have put many efforts on the development of Small and Medium Enterprises (SMEs) to diversity the economy away from mining, to create jobs and alleviate poverty. However, the pace of development of SMEs, after 30 years, is very slow and discouraging. The SMEs failure rate, caused by a plethora of internal and external factors, is now estimated to be over 80%. There is a general consensus among policy makers, politicians, and researchers in Botswana that this trend should not be allowed to continue indefinitely. The purpose of this paper is to investigate the perceived critical management factors (PCMFs) affecting the development of SMEs by collecting primary date from 203 SMEs in 3 cities in the Republic of Botswana by means of questionnaire. Both descriptive and inferential statistics were employed to present the demographic distribution of the sample firms, the identification, ranking and association of PCMFs. The findings showed that five PCMFs (human resources development; organizational development; managerial background; managerial leadership and competitive strategy) affect the performance of SMEs. The PCMFs are strongly related among themselves, indicating the need for a holistic and systematic approach in addressing them. Important relationships were also found between the PCMFs and firm-specific demographic variables such as ownership status, experience and operating period. Recommendations and implication of the findings for future research, policy makers, practitioners in SMEs, and SMEs support agencies and groups were also forwarded.

Abstract: Empowerment is a concept which is widely used in management and many managers and professionals in various claim to be practicing it. Nowadays empowerment has occupied a central point in many organisations of the 21st century. Employee empowerment is said to have benefited many organisations, if managed and nurtured properly especially in enhancing employee commitment and reducing employee turnover. In this era of globalisation there is need for employee empowerment in order to enable organisations to respond quickly to any changes in the macro-environments. Therefore, the aim of this paper was to find out what should be done in organisations to enhance employee empowerment and reduce employee turnover.

Abstract: The main objective of this study was to find out the strategies for success of employee empowerment in organisation to reduce employee turnover. In addition, the study focusses on the benefits and criticism of employee empowerment in organisations. Nowadays, empowerment has occupied a central point in many organisations in the 21st century. In this era of globalization, there is need for employees empowerment in order to enable the organisation to respond quickly to any changes in macro-environment. The methodology adopted in this study is quantitative approach, whereby a convenience sample of one hundred employees was selected for the study. The data was analyzed by using descriptive statistics. This study will contribute greatly to existing literature specifically in inspiring managers to develop appropriate strategies to nurture employee empowerment in organisations. The outcome from the findings shows that employee empowerment is essential to assist organisations to respond quickly to any environmental changes and to reduce employee turnover.

Abstract: Utilizing data collected from a randomly selected sample of 360 academic and managerial staff, regression analysis was performed to identify the determinants of acceptance of change among employees at the University of Botswana. The results showed moderate levels of employee acceptance of innovations and revealed that, of the four categories of substantive factors analyzed, managerial features were the most important determinants of acceptance of organizational change. It was concluded that management action is needed to boost the levels of acceptance of change and that a more participative approach to the management of the change process is necessary to guarantee the involvement of all stakeholders from the decision-making to the implementation and administration stages of the process.

Abstract: More and more companies in the developing world are desiring to export their products to the western world. How ever, in as much as the western world would wish to trade with developing countries, they need some assurance that the products are of the highest possible standards. To date the only standards that are recognized by both western and developing countries are ISO standards. The certification process demands among other things an assurance by the supplier that he (the supplier) has a well documented, effective and efficient procedures for maintaining all records pertaining to its products. This article looks at the case of Botswana Meat Commission, one of the major exporters of beef products in Africa, and shows the procedure it has followed to establish a quality system for managing its records.

Abstract: Average one-dimensional P and S wavespeed models from the surface to depths of 800 km were derived for the southern African region using travel times and waveforms from earthquakes recorded at stations of the Kaapvaal and South African seismic networks. The Herglotz–Wiechert method combined with ray tracing was used to derive a preliminary P wavespeed model, followed by refinements using phase-weighted stacking and synthetic seismograms to yield the final model. Travel times combined with ray tracing were used to derive the S wavespeed model, which was also refined using phase-weighted stacking and synthetic seismograms. The presence of a high wavespeed upper mantle lid in the S model overlying a low wavespeed zone (LWZ) around 210- to - 345-km depth that is not observed in the P wavespeed model was inferred. The 410-km discontinuity shows similar characteristics to that in other continental regions, but occurs slightly deeper at 420 km. Depletion of iron and/or enrichment in aluminium relative to other regions are the preferred explanation, since the P wavespeeds throughout the transition zone are slightly higher than average. The average S wavespeed structure beneath southern Africa within and below the transition zone is similar to that of the IASP91 model. There is no evidence for discontinuity at 520-km depth. The 660-km discontinuity also appears to be slightly deeper than average (668 km), although the estimated thickness of the transition zone is 248 km, similar to the global average of 241 km. The small size of the 660-km discontinuity for P waves, compared with many other regions, suggests that interpretation of the discontinuity as the transformation of spinel to perovskite and magnesiowu¨ stite may require modification. Alternative explanations include the presence of garnetite-rich material or ilmenite-forming phase transformations above the 660-km discontinuity, and the garnet– perovskite transformation as the discontinuity.

Abstract: This article describes a small group intervention for HIV/AIDS prevention among adolescent girls in Botswana. The psychoeducational group model is designed to empower girls to overcome the gender inequality that puts women at increased risk of HIV infection in the country. Group goals include heightening group members' awareness of the influence of the restrictive social messages that surround them and assisting them in developing efficacy and skills to combat the barriers they face. Specific goals, strategies, and interventions for the initial, middle, and termination stages of the group are described. Indigenous and culturally relevant interventions are included in each stage.

Abstract: The use of solar energy is well established for low-grade thermal applications such as water heating and purification. In many of the solar systems, the collector surface located in the Northern Hemisphere faces the true south direction. However, there are occasions in which the radiation received by the collector at various orientations is desirable, such as a collector incorporated with a tracking system. The data for such situations are not available for several solar farms in Nigeria. Consequently, in this study, the average global radiation on flat surfaces was determined for three zones in Nigeria. The total insolation was obtained while the surface azimuth angle was varied between 0° and 75° at 15° intervals. The results are presented for three inclinations of the collector surface, namely L − 10, L, and L + 10 degrees respectively. URI: http://hdl.handle.net/10311/671 Files in this item: 1

Abstract: This study presents the experimental setup and results of measurement of forces and moments in a manually operated ram press machine. Tests were conducted on a BP30 ram press using electrical resistance strain gauges to measure forces present in the machine under operating conditions. The forces were obtained by capturing data for the strains in six channels, using a digital instrument system, and later calculated by using the sensitivity factors. A method was proposed to estimate the tension force and bending moment in the connecting rods based on the sums and differences of measured strains. Results obtained were converted into spreadsheet data and presented in graphs versus the position angle of the operating lever. URI: http://hdl.handle.net/10311/633 Files in this item: 1

Abstract: Most studies consider business performance to be a multidimensional construct. Four dimensions (namely, business growth, profitability, image and customer loyalty, and product service innovativeness) were hypothesised to validate a measure for business performance in the South African context. Using partial least squares, 22 responses from top executives of banks in South Africa were analysed to test the validity of the four dimensions of business performance. The results of the study suggest that the nonfinancial dimensions (namely, image and customer loyalty, and product service innovation) are not valid dimensions for measuring business performance, while the other two dimensions (namely, business growth and profitability) show a high degree of correlation. This indicates that business growth is aligned with profitability, that growth for profitability is a major concern, and that profitability still remains the key measure of business performance in the South African banking sector. Parameters such as customer loyalty and innovativeness are not regarded as important for business performance, although these could be pressing issues for banks. The paper also validates a questionnaire that can be used to measure business performance and reviews various methods for measuring business performance.
