Abstract: Preliminary laboratory studies were conducted to determine the molluscicidal potency of Jatropha curcas, the physic nut. Biomphalaria glabrata and Bulinus globosus snails were exposed to varying concentrations of aqueous extracts of crushed J. curcas seeds from unripe, ripe and overripe fruits collected from two geographically different sites, (Bindura and Kariba, Zimbabwe). Snail mortalities were compared between different developmental stages of J. curcas and between seed collection areas, and LC50 and LC90 values for the different extracts tested were computed. Biomphalaria glabrata was most susceptible to unripe fruit seed extract (with LC50 values of 282 and 389 mg l-1 being recorded for Kariba-origin and Bindura-origin plants, respectively) and least susceptible to ripe fruit seed extracts (with LC50 values of 605 and 708 mg l-1 being recorded for Kariba-origin and Bindura-origin plants, respectively). Bulinus globosus was most susceptible to overripe fruit seed extract (Kariba-origin plants: LC50, 389 mg l-1) and least susceptible to unripe fruit seed extract (Kariba-origin plants: LC50, 687 mg l-1). The area from which fruits were collected did not influence the potency of J. curcas. The potency of J. curcas depends on both the developmental stage of the fruit and the species of the target snail. In view of its many other uses, besides as a molluscicide, we recommend further studies on J. curcas. URI: http://hdl.handle.net/10311/809 Files in this item: 1

Abstract: Multi-proxy analyses on core JO2004-1 recovered from Lake Ohrid (40°55.000 N, 20°40.297E, 705 m a.s.l.) provide the first environmental and climate reconstruction in a mountainous area in Southern Europe over the last 140,000 years. The response of both lacustrine and terrestrial environments to climate change has been amplified by the peculiar geomorphological and hydrological setting, with a steep altitudinal gradient in the catchment and a karstic system feeding the lake. The karstic system was active during interglacials, leading to high carbonate production in the lake, and blocked during glacials as a result of extremely cold climate conditions with permafrost in the mountains. At the Riss–Eemian transition (Termination 2) the increase in lacustrine productivity predated forest expansion by about 10,000 years. In contrast, the Late Glacial–Holocene transition (Termination 1) was characterized by the dramatic impact of the Younger Dryas, which initially prevented interglacial carbonate production and delayed its maximum until the mid- Holocene. In contrast, forest expansion was progressive, starting as early as ca. 38,000 ago. The proximity of high mountains and the probable moderating lake effect on local climate conditions promoted forest expansion, and contributed to make the surroundings of Lake Ohrid favourable to forest refugia during the last glacial, usually steppic, period. Our study of sedimentology, mineralogy, geochemistry, magnetics, palynology and isotopes illustrates the non-linear response of terrestrial and lacustrine ecosystems to similar climate events, and demonstrates the potential of Lake Ohrid as an excellent paleoclimatic archive during the Quaternary.

Abstract: Since attainment of independence, almost every country in East and Southern Africa has introduced some kind of land reform aimed at reconciling indigenous land tenure practices and those introduced by colonial regimes. The reforms have centred on modi"cation of tenurial rules on access, ownership, administration and transfer of land rights coupled with land redistribution and/or restitution in some countries. With the exception of a few countries, such as Botswana, land reforms have largely remained on statute books with little to show on the ground. The paper gives an overview of land reforms in East and Southern Africa, taking Botswana as a case study. It notes that although Botswana has largely been successful in implementing land reforms, it is currently experiencing land tenure problems, especially in peri-urban settlements and inner city low-income areas, despite government's enhanced control over local land administrative structures. The paper ends with suggestions on how to contain the current problems. URI: http://hdl.handle.net/10311/1134 Files in this item: 1

Abstract: This study assesses land-use conflicts in the Okavango wetland ecosystem. A survey of the livelihood activities of a sample of four villages has been carried out and a stakeholder approach used to identify and analyse the key actors involved in resource competition and conflicts in the area. Traditional and emerging stakeholders were identified and found to be in conflict not only with each other but within themselves. Institutional policies on land use in the area are not properly harmonized, and there has been a top-down approach to development planning and implementation of development programmes. As a result, land-use conflicts have escalated in the area. The Okavango Delta Management Plan adopted in 2007 should integrate and harmonize all the land-use policies, and land management in the area.

Abstract: This article reports the findings of a study whose objective was to investigate whether there was a likelihood of a language shift (or loss) from Ikalanga (a minority language spoken in Botswana) to either Setswana or English. The focus of the investigation was 17-25 year olds. The findings indicate that although Ikalanga (unlike indigenous languages like Khoe and Shekgalagadi) is not under imminent threat of loss, there are, nevertheless, clear indications of a gradual shift to Setswana. This conclusion was reached based on informants’ language use patterns and their attitudes towards using their mother tongue, particularly around people with a different mother tongue from them. The results show that informants use Setswana frequently, even in domains where they could use their mother tongue, e.g. when speaking to peers from the same mother tongue. In addition, the responses to a question which required them to indicate which language(s) they would use with their children show that the subjects embrace linguistic diversity (a large majority indicated they would teach their children Ikalanga, Setswana and English), showing no clear conviction to Ikalanga. Some of the subjects also expressed negative feelings towards using their mother tongue around non-native speakers of the language. URI: http://hdl.handle.net/10311/766 Files in this item: 1

Abstract: The article discusses language planning in two Southern African countries, Botswana and Malawi. Both countries are multilingual and multicultural. They also share a common British colonial history. At independence, the two countries retained English as the official language. In Botswana, Setswana was made the national language while in Malawi, it was Chichewa. Over the years, these languages have been developed and promoted at the expense of other indigenous languages, a situation that has prompted linguistic minorities to engage in the language-based politics of recognition. The article discusses how Botswana and Malawi are responding to the call for the official recognition of more indigenous languages in domains such as government, education, and mass media. Relevant comparisons and contrasts between Botswana and Malawi are drawn in this regard in the article. One clear common denominator is the dominance of English in official domains in the two countries. URI: http://hdl.handle.net/10311/829 Files in this item: 1

Abstract: According to the Medical Council of Malawi, one of the conditions for a licence to be granted to an individual who wants to practise medicine in Malawi is the practitioner's ability to speak and write English fluently. This means that the expatriate medical practitioner is not required by law to demonstrate fluency in Chichewa (the national language) or any other relevant indigenous language(s). On the basis of a sociolinguistic study that was conducted at a major referral hospital in a predominantly Chitumbuka-speaking town, this paper argues that the Medical Council of Malawi erroneously assumes that English is the main language of doctor-patient communication in Malawian hospitals since the country is linguistically categorised as an English speaking African country. Yet only a minority of the population is competent in English. The national language (Chichewa), and other indigenous languages remain the main medium through which much of the health service provider-patient communication takes place. A more realistic and comprehensive language proficiency testing should cover English (the main international language of medicine) and at least one indigenous language (the lingua franca of the area in which a particular hospital is located).

Abstract: The genus Lannea belongs to the family Anacardiaceae and consists of 40 species. Lannea nigritana (Sc. Elliot) Keay is a small tree of 3e6 m of height found in the tropical rain forest (Berhaut, 1971; Letouzey, 1972). It is used in the traditional medicine for the treatment of various infectious diseases (Berhaut, 1971; Burkill, 1985). The stem bark of this plant was collected in Makenene, Centre Province of Cameroon in December 2003. The identification was done by Mr. Nana from the National Herbarium of Yaounde where a voucher specimen (N 40408/HNC) documenting the collection is deposited.

Abstract: This article provides traditional and teachers' academic views on school leadership in Botswana. The traditional view is based on the practice used in the kgotla's system. This is a traditional way of engaging all people in a discussion, which has a community or national focus. The system emanates from the pre-colonial leadership approach based mainly on the Setswana proverb that 'kgosi ke kgosi ka batho'. This literally means a leader (king/kgosi) can lead with the support and active participation of those led in the decision-making processes. The academic view is drawn from teachers' understanding of school leadership in their context. The problem is that headteachers are generally seen to be the only school leaders and they too seem not to be actively involving teachers in the school decision-making processes. Their approach is centred in the modern construct of school leadership, which tends to emphasise the importance of a leader. This is in contrast to the Setswana indigenous view, which focuses on group consensus and effort in leading. The study indicates that the two views could be combined to produce a blend of a nationally rich cultural and modern approach to school leadership. The methodology of the study is based on the interpretive paradigm using the interview and the case study as methods. The research suggests that leadership is a concerted effort and effective leadership is possible if the headteacher is de-centred and the focus is on combining the traditional and modern approaches to develop a 'tune' in leadership. Finally it is argued that preparation for school leaders in Botswana should take cognisance of the Setswana culture so that headteachers do not find themselves isolated as a result of their positions but should cooperate with teachers.

Abstract: This article is part of a larger tracer study that investigated Khoe learners' reading ability of English at junior secondary school in Botswana. The research was carried out at Motshegaletau Primary School and Mothamo Junior Community Secondary. The purpose of the study was to examine whether the reading problems identified among Khoe learners at primary level persisted to higher levels of education. The study, which was qualitative, used questionnaires, interviews, classroom observations, students' artefacts, and teachers' schemes and records of work to explore the subjects' reading skills. The findings indicate that Khoe learners lack comprehension strategies, have difficulties understanding implicit reading instructions, lack requisite vocabulary to facilitate reading and writing, do not actively participate in class and are generally slow readers. It is worth noting that some of the problems have persisted from primary level and resulted in poor performance in reading tasks at higher levels of education. The study recommends reading programmes that can empower students and alleviate at least some of these problems. Further, it suggests that teacher training programmes be revamped to equip teachers with necessary skills to handle complexity and deversity in the reading classrooms.

Abstract: The study sought to determine the usefulness of Annual reports information to lenders in Botswana with a view to establishing whether users of financial statement information derive any utility from information presented in the Corporate Annual Report (CAR). The findings on the basis of analysis of responses from seven leaders suggest that financial statement information is required by formal lenders in making the lending decision. The most recent annual reports (RA) appears to be the most favoured. Formal lenders in Botswana make great use of income statements than other components of the annual report. Finally, formal lenders in Botswana regard the audit report as being important to their lending decisions. Notes to the financial statements are not particularly used by these institutions. Also not used is the report from the chairman and the Directors. URI: http://hdl.handle.net/10311/850 Files in this item: 1

Abstract: A number of photovoltaic pilot projects have been started in Botswana since 1990. The first photovoltaic project was Manyana PV project which started in 1992. The Japanese International Cooperation Agency (JICA) PV solar pilot project is the most recent PV solar project in Botswana, which was launched in 2003 at Kudumatse, Motlhabaneng, and Lorolwana villages. The primary objective of all these projects was to access the viability and sustainability of solar energy technology as an alternative source of energy especially for rural based communities. Depending on the findings, such projects were also intended to be replicated in other parts of the country. Despite all these efforts by the government of Botswana and donor agencies, the level of use of PV solar systems for power generation in Botswana, particularly in isolated communities, is very low. This paper, therefore, discusses the factors that impede the rapid development of photovoltaics power generation systems in the rural environment of Botswana. The study is focused on the photovoltaic power generation project which was carried out in three villages in Botswana, namely Kudumatse, Lorolwana and Motlhabaneng.

Abstract: This paper describes a case study that evaluated the level of recycling operations in Botswana. Recycling operations are now recommended as effective waste management strategies for reducing the amount of municipal solid waste disposed at landfill. In assesing the level of recycling operations in Botswana, two companies which are effectively involved in the recycling operation were selected as the focus of the evaluation process. Then data from the two companies is complemented by the data collected from Gaborone landfill site. Finally the role of non-governmental organisations particularly environmental watch Botswana (somarelang Tikologo) is discussed. URI: http://hdl.handle.net/10311/822 Files in this item: 1

Abstract: The concept of a learning organisation is relevant to all twenty-first century organisations because of increasing complexity, uncertainty and change (Malhotra, 1996). Libraries can benefit significantly as learning organisations through reducing complacency; continuous learning, improvement and innovation (Michael and Higgins, 2002); being better equipped to deal with independent and distance learning (Brophy, 2005); serving as a source of competition (Fowler, 1998); promoting inquiry and dialogue; encouraging collaboration and team learning; establishing systems to capture and share learning; empowering people toward a collective vision; and connecting the organisation to its environment (Watkins and Marsick,1993).

Abstract: With the constantly unfolding changes in the educational horizon, the survival and relevance of the library as a repository of knowledge and provider of information services can only be assured in being proactive, swift and responsive. Lifelong learning targets the improvement of “knowledge, skills and competence, within a personal, civic, social and/or employment-related perspective”. It strives to provide learning opportunities on an on-going basis, among others, to the marginalized, isolated, underprivileged and the unreachable. It provides further learning opportunities to adults from diverse backgrounds, already working and people with families and other commitments. It promotes the development of knowledge and capabilities that enable people get accustomed to a world that is knowledge based and equip them to function effectively in the socio-economic milieu in which they live. The resultant liberalisation of learning which brings along such system as open and distance education ensures that where learning takes place and is accessed does not have to be confined to a particular place or time. The controlling variables may depend on the learners and the learning requirements. The swiftness and responsiveness of the library would then require that the old stereotyped order where the library consults or is consulted within its own limited four walls has to be jettisoned, for the emerging and workable new system that is redefined, reshaped and refocused. This paper notes that all the stakeholders of this form of learning who can be found anywhere and everywhere, and may live thousands of kilometres away, require library resources and services. The paper discusses how library should respond to the challenging role in this dispensation. The strategies including possible coalition of libraries, getting the customers equipped with such competencies that will make them information literates, among others, are brought into play. The experience from the University of Botswana’s continuing education programmes and the involvement of the library is factored in. The e-learning initiatives and immense possibilities of other modern technologies, which have not only transformed teaching, learning and interaction processes but are also applicable in the library environment are discussed.
