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

Abstract: Objective: We investigated whether food variety and diversity are associated with physical and cognitive functioning in older adults in Botswana and designed a simple set of screening questions that predict food variety in this population. Methods: Data were collected (1998) as a national household survey of 1085 subjects 60 y and older. A food variety score, based on a food frequency checklist, was calculated by summing the frequency of weekly intakes of 16 food items (0 to 66). A dietary diversity score was calculated as the number of food groups consumed weekly (0 to 5). A representative subsample (n = 393) was randomly selected for the clinical component of the survey, and measurements on dependency and cognitive function were conducted. Results: Low food variety was found: 35.2%, 59.3%, and 22.4% of subjects consumed no dairy products, fruits, and vegetables, respectively. A higher food variety score was associated with urban residence, ownership of cattle, higher education, and more frequent meals, and these indicators were used to construct a nutritional risk indicator. Higher food variety score was associated with better self-reported health and better cognitive function. Similarly, a higher score on the nutritional risk indicator screening tool was associated with desirable health outcomes. Conclusion: A limited number of foods is consumed, leading to an overall pattern of poor food variety. Higher food variety was associated with improved physical and cognitive functions. A screening tool that predicts food variety in this population has been developed and is recommended to be incorporated at a primary care level to identify older adults most at risk of a poor quality diet.

Abstract: This study sought to identify factors that can predict knowledge about HIV/AIDS among adolescents in Botswana. The data were collected through a self administered questionnaire from a sample of 1294 students from schools around the capital city of Botswana, Gaborone. The research instrument consisted of 76 items that solicited information on background characteristics of respondents, indicators of family cohesiveness and bonding of children with their parents, indicators of personal adjustment, evidence of sex life, and knowledge about HIV/AIDS. Most respondents (63.1%) displayed adequate knowledge about HIV/AIDS. The ‘type of job that mothers did’ was the most important single factor that distinguished between students who had “adequate knowledge” from those who did not. Other factors, which could be used to predict knowledge about HIV/AIDS, were, in order of importance: type of family of socialisation, level of education, extent of common residence among parents, level of conflict in the family of socialisation, extent of disagreement with mother and extent to which sexual issues were discussed with members of the family. The study concludes that intervention policies should target students whose mothers do jobs of a low status and should promote family bonding and cohesion.

Abstract: Image processing in the upper Okavango catchment resulted in ten generalised classes which may be used as base line data for monitoring future overall land-use/cover change assessments over the entire upper catchment. Specific work was undertaken using single images for more detailed land-use/cover mapping in a 10 km buffer along all tributaries of the upper Okavango in Angola and Namibia. In terms of the under-developed Angolan upper catchment there is relatively little land clearing at present, and impacts on water use and quality are expected to be minimal in the near future. This is a consequence of 20 years of civil war, while the return of refugees is being inhibited by the prevalence of land-mines. Much more extensive development is taking place in Namibia along the southern bank of the Kavango river. This area is likely to become more intensively used as Namibia attempts to develop greater food security. Further work is required to monitor the impacts from Namibian agricultural expansion. These are likely to be pervasive in terms of the ecology of both the Mahango Game Reserve in Namibia and the Okavango Delta in Botswana. URI: http://hdl.handle.net/10311/936 Files in this item: 1

Abstract: The spatial distribution of aquatic macroinvertebrates in the Okavango River Delta, Botswana, was investigated during the low-water period in February 2003. This complements an earlier study undertaken during high-water in June 2000. Seventy-five samples were taken in a range of aquatic habitats at 29 georeference points in four focal areas: Upper Panhandle (UPH), Lower Panhandle and Guma Lagoon (LPH), Moremi Game Reserve/Xakanaka (MGR), and Chief’s Island (CI). Over 180 morphospecies (approximately 63 families) were recorded during the survey. Multivariate analyses of macroinvertebrate assemblages indicated that assemblages in each of the four focal areas were at least 54% similar at morphospecies level, and 71% similar at family level, although some taxa were more or less common in different areas. Differences in macroinvertebrate assemblages were observed amongst different habitat types, with differences most pronounced between the deltaic habitats and isolated seasonally-flooded pools and temporary rain-filled pools in MGR and CI. The highest number of taxa was recorded in the MGR (125), followed by the UPH (96), CI (93) and the LPH (89) areas. The most families were recorded in the Hemiptera (11), followed by Mollusca (10), Diptera (nine), Coleoptera (nine), Crustacea (six), Ephemeroptera (six) and Odonata (four). Three families of Hirudinea and Trichoptera, and one family of Lepidoptera, were also recorded. Hydracarina were common but not identified beyond order, while Oligochaeta were less frequently recorded. With respect to the different aquatic habitats sampled, the highest number of taxa was recorded in marginal vegetation in the channels and lagoons, although inundated floodplains, floating vegetation and marginal vegetation in backwaters also supported many taxa. The fewest taxa were recorded in sediment. This survey, whilst representing a ‘snapshot’ of the system under low-water conditions, highlights the importance of maintaining a mosaic of aquatic habitats in the Delta. Further studies would enhance our knowledge of the aquatic macroinvertebrate biodiversity of the Okavango Delta, thereby contributing to its conservation.

Abstract: This prelude reflects upon the international ethics conference that was held from December 6-9, 2009, at the University of Botswana in Gaborone, Botswana. Seeking international partners and then forging mutually viable and effectively working links with them is the life blood of a university in a developing country. This partnering is necessary largely because a university in a developing country often lacks resources and affirmation. The resources it lacks range from intellectual capital to funding for its scholarly endeavors. This paper demonstrates how the University of Botswana, as an example of a university in a developing country, has reached out to join hands with a resource-endowed community in the western world through putting up a world class and modern international conference on ethics, one of the most topical concerns in academia.

Abstract: Dorstenia (Moraceae) is a mainly tropical genus of some 170 species (Mabberley, 1987). There are 23 species in Cameroon where a decoction of the leaves is administered for the treatment of cough, headache and stomach pain (Bouquet, 1969). The genus is made up largely of herbaceous perennials with succulent and non-succulent scrambling rhizomes (Berg et al., 1989). The twigs of Dorstenia angusticornis were collected in February 2002 from Kumba South West Province of Cameroon.
