Abstract: A recent model analyzing the role of information and communications technology (ICT) in development shows promise. The model coheres with theory on contingency, the problem of reductionism, and distinctions between deeply and shallowly inscribed organizational change arising from ICT. Conditions of e-readiness at the University of Botswana provide an opportune case study for the model. On the whole the original model holds up well, although the case study reveals relevant factors missed by the model: underlying support infrastructure and postimplementation growth in demand. Accordingly, we define an explicit role for time in the model and add a major new dimension of financial sustainability. These additions equip the model to better account for realities affecting ICT’s role in development. Further research needs include case and cross-case studies of the revised model.

Abstract: Market effeciency is an area enormous interest in the financial literature. Numerous researches conducted imperical in testing weak-form market effeciency in several stock markets and employed various techniques but the empirical evidence in controversial. Triangulation econometric approach is employed to assess the predictability of daily return series of the Botswana Stock Exchange (BSE) and to test the null hyphothesis of random walk model. The empirical results reject the null hypothesis of random walk model for the daily return series of BSE for the period of 1989-2005 and evidenced serial autocorrelation of return series, which clearly indicate predictability and volatility of security prices of Botswana market. However the empirical evidence of both non-parametric and parametric test reject the hypothesis of random walk model and indeed violate the notion of weak-form market efficiency.

Abstract: Since the first clinical evidence of AIDS was reported two decades ago, HIV/AIDS has spread to every corner of the world. Still rapidly growing, the epidemic is reversing development gains, robbing millions of their lives, widening the gap between the rich and poor, and undermining social and economic security. Mission is carrying out God's work among people who are struggling to live with dignity and wholeness…Mission is to proclaim the good news that God affirms life over death, and that God acts among the poor, the majority of whom are women, who are victimized in the globalization of the market economy and left out in decision making processes. Mission is forming partnership…to struggle for life and work for justice for all people.” Traditionally, Jesus' own mission (Luke 4:18–19) and its mandate have been understood primarily in terms of proclaiming the word. What would be the further implications of seeing this mission also as that of spreading fire upon the earth? URI: http://hdl.handle.net/10311/762 Files in this item: 1

Abstract: The purpose of this article is to explore and propose a way of using power as a theoretical anchor to investigate the information behaviour of people in work roles. The paper reviews literature on power relevant to the information disciplines. Various models of power are described, and a more sophisticated view, which takes a relational approach to power, is used to suggest how information related behaviour could be investigated. In this paper, power is regarded as a pervasive phenomenon involved in all aspects of individual lives, including the aspects emanating from work roles performed by individuals, thus manifesting itself as part of the relationships in the organisation. The paper suggests a framework that links information behaviour to power by arguing that power relations that form part of the processes of the work roles induce the information behaviour exhibited by those people. The paper concludes by pointing to a need for information behaviour researchers to consider power as central to understanding how people seek and use information. The framework could be used as a tool for designing studies that will enable the collection of data on information behaviour. URI: http://hdl.handle.net/10311/749 Files in this item: 1

Abstract: The experimental techniques of attenuated total reflection and grating-coupling were originally employed separately as probes for surface polaritons. However, as far back as the mid-1970s, some value was found in actually combining them into a single tool for probing elementary surface excitations. In this article, the theory of the two methods combined into one probe for surface polaritons is presented. The main results of the calculations, here, are the firstorder diffuse reflectivities, which arise due to the presence of a classical grating. For the ease of presentation, only a semi-infinite specimen is considered and the grating is thought to be deposited only on one interface. The discussion highlights the advantages the combined technique has over either of the two methods when each is employed on its own. URI: http://hdl.handle.net/10311/195 Files in this item: 2

Abstract: The experimental techniques of attenuated total reflection (ATR) and grating coupling were originally employed separately as probes for polaritons. The combined technique of these methods into a single probe is a very versatile tool for probing elementary surface excitations. A theoretical investigation of this single probe for surface polaritons, ATRgrating coupling, is undertaken. The emphasis is on the calculations of first-order diffuse reflectivities, which arise due to the presence of a classical grating. More specifically, the ATR set-up in the Otto configuration is considered and for ease of presentation of the results, a classical grating is thought to be deposited on only one interface of a surface-active thin-film specimen. The discussion highlights the advantages the combined technique has over either of the two methods when each is employed on its own. URI: http://hdl.handle.net/10311/233 Files in this item: 2

Abstract: This study investigated the perceptions on pre-service or student teachers regarding their teacher education program. Data was collected through in-depth semi-structured interviews with 17 pre-service student teachers in one primary college of education in Botswana. In addition, there was an analysis of documents from the Ministry of Education and Skills Development that outlined how the training of pre-service teachers should be run. Participants indicated that they spend too much time learning/exploring theory and less time of hands on experience. Research has also shown that teacher education overemphasize theory and focus less on practice in the preparation of pre-service teachers. The study results indicated that student teachers are taught too much theory and did less of teaching practice. Pre-service teachers should be given more time to do teaching practice and less time on content, as they need the application skills more than they need the content. Based on the findings in this study, it is recommended that the Tertiary Education Council in Botswana should revise the teacher education training program and to reconsider increasing the amount of time for teaching practice for the pre-service teachers.

Abstract: The melt-quenched Sn10Sb20Se70 sample in the bulk form was used to prepare films on well-cleaned glass substrates by thermal evaporation method. The activation energy for glass transition (apparent) and crystallization has been analyzed by using the Kissinger formulation. The X-ray diffraction study shows the crystallization of Sb2Se3 phase in the major proportion as compared to the SnSe2 phase. The SEM images film of the show the appearance of spherical globules upon annealing below the glass transition temperature. The effect of annealing temperature on the electrical and optical properties has been studied. A linear fit between DE and Eo is observed, indicating the validity of Meyer–Neldel rule with the change in the annealing temperature.

Abstract: Bulk glasses of the Sn10Sb20−xBixSe70 (0 x 8) system were prepared by the conventional melt quenching technique. Thin films were prepared by the thermal evaporation technique on glass substrates. Appearance of some crystalline phases is observed from the X-ray diffractograms after heat treatment below the glass transition temperature for 1 h. Scanning electron microscopy studies also show the presence of microcrystalline phases in the amorphous matrix after annealing for 1 h. The effect of Bi concentration and heat treatment on the optical gap and activation energy for dark conductivity were also investigated for the pristine as well as annealed films. The results are discussed on the basis of models related to the presence of defect states in chalcogenide materials. URI: http://hdl.handle.net/10311/534 Files in this item: 1

Abstract: The extent to which teachers perceive the existence of pressure emanating from negative stereotype of teaching as a career by the society tends to reduce the amount of affective and cognitive investments on teaching and learning by teachers and teacher trainees. Given this problem, the purpose of this study was to determine the level to which stereotype threat as perceived by University of Botswana (UB) teacher trainees influences their learning- and teaching-related behaviour. To test the nine research hypotheses posited to guide the study, data for the inferential survey study was collected using a validated 48-item questionnaire from a sample of 452 UB teacher trainees. Data analyses were done using t-test of single mean, chisquare (72) test and one way analysis of variance (ANOVA). The findings showed that the level to which UB teacher trainees perceived teaching as a stereotyped career significantly influences the amount of affective investment they are making on their training programme and hope to make on their teaching. These findings were discussed and recommendations that emanated from findings were made. URI: http://hdl.handle.net/10311/1082 Files in this item: 1

Abstract: Examines the relationship between TQM perceptions, planning behaviour, and firm size in SMEs in Ethiopia. Primary data were collected from 57 SMEs through a questionnaire. However, as the study is a preliminary investigation, uses only simple descriptive statistics to analyse the sample data. The results are not significantly different from those of previous studies in SMEs. TQM perceptions vary with firm size and planning behaviour. The findings also indicated that excessive emphasis on short-term profitability, lack of resources, business planning and vision, and misperception of TQM practices are among the main obstacles to the adoption of a formal TQM program. Suggests some lessons and implications for future research. URI: http://hdl.handle.net/10311/192 Files in this item: 2

Abstract: Solar energy is finding wide application via several energy-saving devices and systems. Its use, especially in rural areas, can often be limited by the non-availability of complete information on insolation data. In this investigation, both the mean extraterrestrial and terrestrial radiations were calculated for three zones in Nigeria. These zones were assumed to be dependent mainly on the latitude, L. The isotropic model was employed for the computation of the diffuse and ground reflected components of radiation. Consequently, the total insolation was obtained for various inclinations of the collector surface. It was found that three solar energy seasons exist for each zone. For maximum total incident radiation, a different collector inclination is ideal for each solar energy season. However, for all year round applications, a fixed inclination varying between L and (L+10) degrees is recommended. URI: http://hdl.handle.net/10311/672 Files in this item: 1

Abstract: This article explores what would be the most probable scenario for the tourism industry in Botswana by the year 2020. A modified Delphi technique was used to generate data from 68 industry experts. The findings show that experts forecast progressively more changes and higher impact as one moves from values, structures, and events. The implication for policy makers and industry operators is that efforts aimed at increasing tourism may prove more fruitful if focused on changing structures and hosting events, rather than changing the values of the people. The study also improves on the understanding of Delphi forecasting behavior. It demonstrates that an expert who is optimistic on one factor—say, values—is likely to perceive the same with regard to other factors such as structure and events.

Abstract: Moremi game reserve (MGR) in northern Botswana is one of southern Africa’s most popular destination because of its impressive wildlife and wilderness areas. To maintain the wilderness nature of the park and game reserve, the Government has pursued a policy of high cost-low volume which is not necessarily based on demand and supply characteristics of the tourist market. The present study determines the perceptions of self-drive tourists and clients of mobile tour operators on the prevailing park fees in MGR and uses the contingent valuation method to determine their willingness to pay (WTP) for park fees under a management scenario in which the management of the game reserve would be improved by a hypothetical international conservation organization. Data collection involved a self-fill of a questionnaire by these tourists in the game reserve. In the first scenario the mean entrance and camping suggested by nonresidents was higher than the prevailing fee. Residents suggested a lower entrance fee. In the hypothetical scenario, the mean maximum WTP for entrance and camping fee for South African and overseas tourists were higher than in the first scenario. There was a significant difference in the WTP for entrance fee between overseas tourists and South African tourists (p<0.05). Overall expenditure was significantly related to the WTP for increased park fees. The paper concludes by suggesting improvement in the MGR’s facilities for better satisfaction of tourists.

Abstract: The social and economic disadvantages faced by women, particularly in developing countries, has long promoted inquiry into gender stratification in the major socio-economic infrastructures. Higher education has increasingly become instrumental in giving women the knowledge, skills and self-confidence necessary to gain their rightful position in society. Despite the serious attempts made by higher education institutions in formulating and implementing gender conscious policies and programs, the participation of women is far from satisfactory. Furthermore, the pace of progress in attitudinal and behavioural changes in both men and women is very slow as socio-culturally instigated impediments are still alive. The purpose of this paper is to examine the current status of gender equality in the higher education system of Botswana. Data on students and staff on the University of Botswana were collected from secondary sources and analysed using simple tabulation techniques. Some suggestions are forwarded to achieve gender excellence in high education. URI: http://hdl.handle.net/10311/184 Files in this item: 2

Abstract: “Sustainable development” as a concept was popularised by a 1987 report of the United Nations World Commission on Environment and Development. The report defined sustainable development as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs”. However, from this definition, we cannot ascertain the central intuition of the notion of sustainable development. Failure to do this makes it difficult to derive methods that can be used to formulate effective intervention policies that can enable nations to attain sustainable development. This paper briefly reviews various schools of thought in popular literature on the notion of sustainable development, exposes their weaknesses and develops a holistic notion of sustainable development based on the systems approach.

Abstract: This paper investigates the extent to which the differential urbanisation model is applicable to Botswana by using empirical data obtained from periodic censuses, supportive documentary information and observations from personal on-going research on urbanisation and migration. Differential urbanisation refers to the cyclic spatio-temporal growth trends that the elements of human settlement hierarchies undergo, in response to migration. Empirical studies have verified the validity of differential urbanisation in the United States, Europe, India and South Africa. These areas, unlike Botswana, have longer histories of urbanisation, larger population sizes, denser population distributions, and higher levels of economic development. Current research interest is focused on investigating the theoretical applicability of the differential urbanisation model to those countries at the lower end of the economic development spectrum. The rationale and thrust of this paper is to therefore investigate the relevance of differential urbanisation under unique environmental, demographic and socio-economic conditions that pertain to Botswana. Evidence from the paper shows that urbanisation in Botswana has occurred in sequenced phases that, in general, resemble those suggested by the differential urbanisation model in the following ways. First, there has been concentration in the primate city due to mainstream migration. Secondly, there has been fission leading to the fast growth of the adjacent intermediate settlements, partly as a result of deglomeration economies at the primate core accompanied by substream migration. Third, the peripheral regional and rural centres appear to be now growing relatively rapidly, in response to the implementation of decentralisation policies.

Abstract: Obedience is traditionally the supreme virtue of the military and, for many people, a soldier is an unthinking automaton that has been conditioned to respond to commands and operate in strictly hierarchical environments. But as soldiers progress in rank, they are required to distinguish between legitimate and illegitimate commands as well as to reason concerning their commands and other military and non-military engagements. This paper is an overview of the practical steps adopted to foster independent thinking among student officers at the Botswana Defence Command and Staff College. It shows how the tools of critical thinking can be used to help student officers overcome the lessons of unquestioning obedience ingrained in them at cadet training and gain an awareness of themselves as autonomous individuals with responsibilities to and beyond the military hierarchy. It also shows how critical thinking can assist in the evaluation of military objectives and in the decisions that follow such evaluations. URI: http://hdl.handle.net/10311/795 Files in this item: 1

Abstract: This study examined the extent of accomplishment of the goal of the world of work in social studies classes at the primary and secondary school levels in Botswana. Data were collected through questionnaires administered in both rural and urban schools nationwide. The researchers also interviewed teachers, students, school leavers, members of the public and the business community. Purposive, convenience and simple random sampling procedures were employed. The findings revealed that the goal of the world of work is not sufficiently achieved due to a number of factors such as the congested nature of the social studies syllabus, the theoretical nature of the methods used in delivering its contents, lack of equipment in schools and inadequate training of teachers on topics and concepts related to the world of work. Several recommendations were proffered, for example the need to review the syllabus so as to realign it to the demands and challenges of the work world; teachers should be well trained so that they can adequately prepare students for the challenges ahead, schools should be adequately resourced with computers and other forms of modern technology and that collaboration between schools and the business community be of high priority.
