Abstract: This paper examines the practices of traditional healing and how they are integrated or rejected by the African Independent Churches (AICS)in Botswana. The paper argues that in spite of some doubtful elements of rejection in the AICS, there is a large degree of integration of healing in the AICS Botswana. The story of this paper is based on a long discussion with a prophet healer who does not have a clear view of his position with respect to integrartion of healing in the AICS and traditional healing.

Acceptance of blackboard technology by mechanical engineering students at the University of BotswanaUziak, J. (Tempus Publications, NaN, 2009)[more][less]
Abstract: Technology-based teaching and learning is entering academic life at an amazing rate. It comes whether invited or not. Students and lecturers are confronted with new technologies. There are new teaching methods to accompany them, and new pressures to use them. E-learning is penetrating all areas of teaching and learning: academic institutions and corporate training alike. It has been generally accepted as a major and viable component of higher education. However, it is not clear how students accept the use of new technology. This paper deals with the question of acceptance by analysing the University of Botswana engineering students' reflection on Blackboard technology.

Abstract: Lack of access to safe or improved water supply in developing countries is a major global concern, since water is a basic need for sustenance. Programmes aimed at improving access to safe water have been implemented in several sub-Saharan countries. In Botswana, only gazetted settlements have access to water and other basic services provided by the government. This paper examined the level of access to safe water, effort required, and problems encountered in collecting water by households in ungazetted settlements. The paper also investigated whether households in these settlements were willing to pay for improving access to water. The study has been undertaken on settlements located along the Boteti River in the North West District of Botswana. The majority of households in ungazetted settlements satisfy their domestic water requirements through abstracting untreated water from river flows and hand-dug wells when the river is not flowing. Men dominate in collecting water in ungazetted settlements, with the most dominant mode of transporting water being the use of donkey carts. The dominance of men in water collection and use of donkey carts is due to water sources being too distant from homesteads. This has resulted in low water consumption levels, with the per capita water consumption being less than 20 l/capita/ day for most households. Such low levels of water consumption adversely affect attainment of desirable personal hygiene and food preparation. The opportunity cost of time for water collection has been estimated at 1.80 Botswana Pula (P) and the price of water is estimated to be P18/m3 (1.00 P = 0.1755 USD on 18 November 2005). This is higher than the price paid by households residing in rural settlements obtaining water from government or district council water supply schemes. The majority of the households were willing to make a once-off contribution towards improving access to potable water with the mean willingness to pay (WTP) being P161 per household, or just over a third of the statutory agricultural minimum wage in Botswana, P589/month. The potential contribution by household to an improved water supply is significant for a largely unemployed rural population. URI: http://hdl.handle.net/10311/502 Files in this item: 1

Abstract: During the past decade, significant progress has been made on how to accommodate and teach learners with disabilities. However, less research has been done on creating a conducive learning environment for learners with disabilities. The purpose of this study was to determine the accessibility of Family and Consumer Sciences (FCS) laboratories for learners with mobility problems. The focus of this study was on the accessibility, reach ability, and safety of FCS laboratories. Fifty junior secondary schools in the South Central Region of Botswana were selected for the study. A questionnaire and an accessibility checklist were used to evaluate the laboratories’ current situation. The findings indicate that all FCS laboratories investigated were not designed to meet the needs of learners with mobility disabilities. URI: http://hdl.handle.net/10311/1089 Files in this item: 1

Abstract: This study proposes a technique of accessing applications from multiple file servers in a computer network that caters for a large user community. The technique is a step towards creating a computer network system that is simple to implement, scalable, easy to manage, transparent to the user and suitable for a university type environment. The proposed technique has some features of a distributed system, but is not as complex. It is built around a very popular commercial network operating system called Netware.

Abstract: The purpose of this study was to determine if auditing firms in Botswana have begun to provide services beyond traditional auditing. It also sought to establish whether income from such services was significant compared to income from auditing, and whether audit firms in Botswana have in place mechanisms to assure quality audit work. In view of these, an attempt was made to establish the professional independence status of Botswana public auditors.Data for the study was collected from thirteen audit firms on the basis of the register of auditors maintained by the Botswana Institute of Accountants. The results showed that audit firms in Botswana provided other services beyond the traditional audit work. The collective income obtained from these other services exceeded that generated by professional audit work. We also found that audit firms had some mechanisms in place to ensure quality audit work. However, most of the audited companies did not use audit committees and the audit firms did not recommend their use. The evidence was not sufficient to explicitly judge independence, but the results suggested that perceived auditor independence could be affected.

Abstract: The World Health Organisation called for research assessing the safety of electronic cigarette (e-cigarette). We evaluated the acute effect of active and passive e-cigarette and tobacco cigarette smoking on complete blood count (CBC) markers in 15 smokers and 15 never-smokers, respectively. Smokers underwent a control session, an active tobacco cigarette smoking session, and an active e-cigarette smoking session. Never-smokers underwent a control session, a passive tobacco cigarette smoking session, and a passive e-cigarette smoking session. The results demonstrated that CBC indices remained unchanged during the control session and the active and passive e-cigarette smoking sessions (P > 0.05). Active and passive tobacco cigarette smoking increased white blood cell, lymphocyte, and granulocyte counts for at least one hour in smokers and never smokers (P < 0.05).It is concluded that acute active and passive smoking using the e-cigarettes tested in the current study does not influence CBC indices in smokers and never smokers, respectively. In contrast, acute active and passive tobacco cigarette smoking increase the secondary proteins of acute inflammatory load for at least one hour. More research is needed to evaluate chemical safety issues and other areas of consumer product safety of e-cigarettes, because the nicotine content in the liquids used may vary considerably.

Abstract: The article argues that, historically, universities have served a select few individuals as part of modernist not transformative agenda. This highly selective process guarantees students good life. The article argues that university education helps to redress colonial inequities through creating opportunities for graduate employability. However, university education has also served conflicting roles of adhering to the global capitalist imperative and attempting to inculcate social inclusion in developing nations. The roles of university-based adult education is analyzed in terms of its curricula, teaching, and research to demonstrate that adult education serves officialdom and has strayed from the initial adult education focus of social transformation. Drawing some illustrations from the Department of Adult Education at the University of Botswana, the article argues that programs serve state interests through engaging in a neoliberal modernist curriculum that excludes the learners. Finally, it is suggested that adult education should rethink the curricula, strengthen civil society, and mobilize community for social transformation.

Abstract: While the western powers credit globalization with facilitating development, Africa continues to face challenges such as poverty, low quality education, HIV/AIDS, and ineffective governance. This article provides an overview of African development since independence arguing that the African states shifted from their service-based policy agenda of the 1960s during the boom and bust period in the 1970s and 1980s, experienced the drastic effects of structural adjustments in the 1990s, and are now attempting to pursue an African renaissance agenda. It demonstrates how adult educators can help create deliberative democracy by working with civil society to engage African communities in public discourse and empower the citizenry.

Abstract: Aeromagnetic (AM) and Landsat Thematic Mapper (TM) data from the south-central Zimbabwe Craton have been processed for the purpose of regional structural mapping and thereby to develop strategic models for groundwater exploration in hard-rock areas. The lineament density is greater on TM than on AM images, partly due to the resolution of the different datasets, and also because not all TM lineaments have a magnetic signature. The derived maps reveal several previously undetected lineaments corresponding to dykes, faults, shear zones and/or tectonically-related joints, striking predominantly NNE, NNW and WNW. We suggest the possible hydrogeological significance of some of these patterns as follows: the aeromagnetic data can be used to map faults and fractures of considerable depth which are likely to be open groundwater conduits at depth (typically under tension), while TM lineaments, although not necessarily open (mostly under compression), represent recharge areas. The interpreted persistent lineation and well developed fracture patterns are correlated with existing boreholes and indicate a spatial relationship between regional structures and high borehole yields (N3 m3/h). This relationship is combined with other lithological and hydrogeological information to identify potential regional groundwater sites for detailed ground investigations. These are defined as dyke margins, faults, fractures/joints or intersections of any combination of these structures. Priority should be given to coincident AM/TM lineaments (e.g., NNW and NNE fractures) and continuous structures with large catchment areas (e.g., NNE and WNW faults). The late Archaean (2.6 Ga) granites are considered the most favourable unit because of their associated long and deep brittle fractures between numerous bornhardts (inselbergs) and kopjes. Several small-scale TM lineaments also form important local sources of groundwater for hand-dug wells. Based on measured rock susceptibilities from the area, we present a model of the typical magnetic responses from the possible groundwater exploration targets. The developed magnetic model could be applicable to similar terrains in other Archaean Cratons. URI: http://hdl.handle.net/10311/341 Files in this item: 1

The Africa Growth and Opportunity Act (AGOA) trade regime: Opportunities and challenges for BotswanaMokhawa, G.; Osei-Hwedie, B. (Botswana Society, http://www.botsoc.org.bw, NaN, 2003)[more][less]
Abstract: For a long time now, African countries have been demanding increased trade with the developed economies of the West as a means to promote economic development. 'Trade not aid,' has become the hallmark of this demand. Increased trade is to be realized through preferential access to developed economies markets, especially in manufactured goods. It is hoped that exports of manufactured goods would propel industrialization and help diversify economies away from traditional raw material exports. The USA has responded to Africa's demands through the Africa Growth Opportunity Act (AGOA) that allows Africa access to the world's biggest and most lucrative market. This article examines the objectives of, and benefits under, AGOA with a view to analysing the opportunities it creates for Botswana's economic diversification into manufacturing, especially in the case of textiles and apparel industries; and the challenges it poses for Botswana. Analysis of the challenges help us to highlight not only Botswana's internal weaknesses and problems but also that of the AGOA provisions, as well as pose the question of who benefits, helping us unravel the US motives behind AGOA.

Abstract: This article draws on existing literature and a field study conducted by the writer to explore the problems faced by African females when studying abroad. A comparative perspective is adopted and, whilst it is recognised that women are particularly disadvantaged in general, the principal thesis is that African women are particularly disadvantaged, especially when they undertake studies abroad. The article describes and analyses the disadvantages faced by women broadly throughout the world, by African women in general and in education in particular, and the difficulties they face when studying abroad. The implications for policy practice and research are considered and some short-and long-term strategies suggested whereby improvements could be effected.

Abstract: The Precambrian rocks of northern Botswana comprise poorly exposed igneous complexes, high-grade metamorphic rocks, as well as sedimentary sequences including mainly siliciclastic and carbonate rocks. New U-Pb SHRIMP data are presented for detrital zircons from siliciclastic rocks collected from the Shakawe area in northern Botswana. These data show three main age groups at c. 1020 Ma, 1090 Ma, and 2050 Ma which support contentions for local provenance of the sediments. They also fix the maximum age of the deposition of these siliciclastic rocks at 1020 Ma. The results support field evidence suggesting that the siliciclastic rocks exposed in the Shakawe zone are part of the Ghanzi-Chobe Supergroup.

Abstract: This study examined the relationship between family factors and secondary school students’ aggressive and antisocial behaviours. Participants were 1,478 junior and senior secondary school students from four major urban centres in Botswana, aged 12-20. Results showed significant prevalence of self-reported aggressive tendencies and antisocial behaviours among secondary school students in Botswana. Boys rated themselves higher on aggression, use of alcohol and drugs and carrying and using dangerous weapons compared to girls. High scores on antisocial and aggressive behaviours were significantly related to poor parent-child relations and low parental monitoring. The results are consistent with findings from previous studies. The findings have important implications to violence prevention programs for children and adolescents. Suggestions for future research and the development of intervention programs are made. URI: http://hdl.handle.net/10311/514 Files in this item: 1

Abstract: This paper explores the linguistic contexts, uses and meanings of the colour terms ntsho (black) and tshweu (white) in Setswana. Using a corpus data, the paper argues that the two terms display cultural and linguistic meanings which are sometimes lacking in Setswana dictionaries and certain translations. The analysis of the data reveals that the two colour terms collocate with a variety of other words in the language to result in a complex array of meanings. Further, the analysis reveals that while traditionally ntsho is associated with negative semantics, it is used in a variety of senses to celebrate heroes and heroines in Setswana culture. In a similar way, tshweu has ngative senses in certain limited contexts. URI: http://hdl.handle.net/10311/856 Files in this item: 1

Abstract: This paper describes a new method of determining the feedback coefficients in a state variable feedback system, given the closed loop transfer function, making use of the transfer function between different and relevant points in the feedback configuration used to realize the desired closed loop transfer function, formulas that can be repetitively used to determine the feedback coefficients are desired. The usefulness and simplicity of these methods are demostrated by illustrative examples where the plant has complex poles, coincident poles and zeros and even when the plant is unstable.
