This study assessed the digital preservation capability maturity readiness within the context of e-government in Botswana Public Service with a view to developing a strategic framework that ensures digital continuity. There some studies that have been conducted in Botswana regarding digital preservation but they did not provide a framework which could be used as an assessment to check their capability in digital preservation as e-government progresses so that digital information is continuously being used for decision making over time. The study adopted a pragmatic paradigm and embedded mixed method approach; whereby a cross sectional survey and case study were deployed in each of the 6 selected ministries as a unit of analysis. The target study respondents comprises of 5 Senior Managers, 4 Managers - Human Resources and Administration, 6 ICT Managers, 40 Records Management Officers,12 Information Technology Officers, 1 Performance Improvement Coordinator, 1 Project Manager, 8 Archivists, 1 Assistant Deputy Manager and 1 Deputy Managers- Management Services. The data was collected through interviews, questionnaires, personal observations, and documents analysis. Both qualitative and quantitative data were collected sequentially and simultaneously where one form of data supported or complemented each other so as to have one form of data play a supportive role to the other. Data analysis was achieved through the triangulation of both qualitative and quantitative data in order to yield a single interpretation and conclusion drawn. The findings of the study showed that the Botswana Public Service has no unified national information systems used to manage public sector records leading to some ministries adopting their own electronic records management systems. Currently few ministries have implemented the electronic records management system and majority of the digital records are not preserved due to lack of preservation guidelines and strategies. The study further established the lack of preservation policies and skills in managing and preserving digital records in Botswana Public Service. In that regard, the study developed a strategic framework for digital preservation capability maturity readiness in the context of e-government in the Botswana Public Sector. The ultimate aim of the framework is to ensure digital continuity and make sure that e-government is sustained for the benefit of an open government and increased participatory citizenry. / Information Science / D.

Contemporary conservation and development understanding in both policy and academic circles espouses that natural resources have a significant contribution to the livelihoods of local people and that knowledge of this can better foster conservation policies that are consistent with livelihood and ecological needs. This thesis is based on research conducted in the southern Kalahari region, South Africa among the San and Mier communities bordering Kgalagadi Transfrontier Park. It looks at the importance of natural resources to the San and Mier community groups and ascertains the extent of resource use and its value within broader livelihood portfolios. It also focuses on the cultural values of natural resources and interactions among institutions and actors and how these shape natural resource governance and livelihood outcomes. Overall, natural resources represent an important livelihood source contributing up to 32 % and 9 % of the total income of the San and Mier respectively or up to 46 % and 23 % if livestock incomes are included. However, the dependence on, diversification patterns and distribution of natural resource income vary substantially between and within the two communities. With regards to the cultural values attached to natural resources by the San and Mier, the findings show that these arise from an incredibly diverse and sometimes conflicting array of values that punctuate the two communities’ way of life and they are inextricably linked to resource use. Lastly, governance of natural resources in the co-managed Park and communitymanaged resettlement farms is characterised by complex institutional arrangements, compounded by the existence of multiple actors that have multiple and sometimes conflicting objectives – as shaped by different meanings and interpretations of natural resources. Heightened inter- and intra-community conflicts are common, notably resource use conflicts between the San and Mier and between the San ‘modernist’ and ‘traditionalist’ groups. This demonstrates that the communities’ livelihood dynamics in general and the dependence on natural resources in particular, are closely linked with ecological, economic and social factors including history, culture and present livelihood needs. By exploring the social-environment interactions, the study highlights the complexities and diversity of resource use for livelihoods that should be taken into consideration for both conservation and development policy interventions and research. The main argument of the study is that the contribution of natural resources to local livelihood portfolios in co- and community-managed areas, can be better understood through a consideration of cultural dynamics and institutional arrangements since these condition natural resource access, value and use.

This research was stimulated by an indication that members of the Africa Gospel Church do not utilise professional health care services optimally, probably due to religious reasons. This may also be the result of registered nurses’ inability to render culture congruent care. To render culture congruent care, nurses require knowledge of the belief system and the health seeking behaviours of the church members. The qualitative research investigated the religious beliefs and health seeking behaviours of members of the Africa Gospel Church in Francistown, Botswana. An exploratory ethnonursing research method was applied. Semi-structured interviews were held with two purposively selected samples. Qualitative data analysis was done using computer software to reduce data and interpret the research results. The study indicated that members utilise the Church structure for health care purposes and seek health care mainly from priests and prophets. / Advanced Nursing Sciences / M.A. (Nursing Science)

The application of information communication technologies (ICTs) in records management in many organisations underscores the need for the assessment of e-records readiness. This provides a useful guide in benchmarking, gauging progress and comprehending e-records management. This study examined e-record readiness in labour organisations with a view to proposing a framework for labour organisations in Botswana. The study was largely guided by a quantitative paradigm and used a survey research strategy. This was complemented by methodological triangulation of both quantitative and qualitative data collection methods. All the 50 registered labour organisations in Botswana were surveyed, 45 of which responded, representing a response rate of 90%. Data was obtained through structured questionnaires, semi-structured interviews, document review and observations. The study established that e-records readiness in labour organisations in Botswana was evident, low and evolving, evidenced by the slow adoption of ICTs; inadequate records management standards and practices; and low integration in the national e-readiness framework. The study confirmed that most labour organisations had embraced the utilisation of ICTs in their work; exhibited some form of records management function and acknowledged the existence of national policy directives and strategies on e-readiness. However, traditional ICTs mainly the fax and telephone, were more prevalently adopted and used than newer ones such as e-mail and the Internet. The use of social media technology (Web 2.0 - Facebook, YouTube, and Twitter) was yet to be explored. The management of both paper-based and electronic records was not satisfactory and fell short of best recognised records management standards and practice. The integration of labour organisations into national e-readiness initiatives as espoused in key policy proclamations within the context of the pursuance of a holistic knowledge and information society was slow and remained challenging. In order to foster successful e-records readiness in labour organisations, several recommendations were advanced that underscored effective ICT adoption and use, implementation of best records management practices and rigorous integration of labour organisations into the information and knowledge society in Botswana. In addition, an integrated framework for examining and understanding e-records readiness in labour organisations was proposed and documented. / Information Science / D. Litt. et Phil.

The main aim of this study was to investigate the implementation of the performance management system in the Ministry of Foreign Affairs and International Co-operation of the Botswana public service and to identify the factors that facilitated and hindered the successful implementation of the programme. This study used a mixed methods research design which combines both qualitative and quantitative research design. The study used the model of social programmes, which is a holistic and comprehensive analytical framework that is used to study the implementation of social intervention programmes. Research data was obtained using a triangulation of research methods (case study, evaluation research and survey method) and data sources (literature review, document analysis, self-administered questionnaires and follow-up personal interviews). A sample of 90 respondents was selected using the purposive sampling strategy. The study found that the implementation of the performance management system in the Ministry of Foreign Affairs and International Co-operation was problematic because of unclear and ambiguous foreign policy goals and objectives; lack of broad-based support and critical mass of champions of the performance management system; use of command-and-control management model rather than empowerment and the adaptation model; inadequate human and institutional capacities; ineffective supporting systems of the performance management system; weak accountability and responsibility mechanisms; weak intra-ministerial and inter-ministerial communication, co-operation, collaboration and co-ordination; inadequate information and communications technology infrastructure and unfavourable international environment. This study contributed to the existing literature by investigating the implementation of the performance management system in the global environment from a public service perspective rather than a private sector perspective, which relies on the experiences of multinational companies. The study findings provide some invaluable insights that may improve the implementation of the performance management system in the Ministry of Foreign Affairs and International Co-operation of the Botswana public service by proposing recommendations to the identified problems. The recommendations include: setting clear and specific foreign policy objectives; creating a critical mass of champions of the performance management system; strengthening human and institutional capacities; promoting effective implementation and use of supporting systems of the performance management system; strengthening accountability and responsibility mechanisms; strengthening intra-ministerial and inter-ministerial communication, co-operation, collaboration, and co-ordination; strengthening decentralisation and empowerment principles and upgrading information and communications technology infrastructure. / Public Administration and Management / DPA

The purpose of this study was to determine factors affecting non-adherence to Anti-retroviral therapy among AIDS patients. A cross sectional quantitative survey, was used. Structured interviews were conducted with 300 ART patients. Data were analysed using SPSS version 13 and presented in charts, graphs and frequency tables. Motivators of good adherence were identified as disclosure of HIV positive status to more than one person, frequent adherence counselling, self-efficacy to adhere to ART, positive interactions between patients and healthcare providers; and using an adherence partner. Barriers to adherence were forgetfulness, transportation costs to and from the clinic, time away from work and side effects. There was a strong positive correlation between adherence, CD4 counts and viral load. Adherence was closely tied to immunologic and virologic improvements. Respondents with poor adherence were likely to have unsuppressed viral loads (OR 12.98, 95%, CI 4.9-34). / Health Studies / Masters of Public Health

Modern day society is characterised by the availability of technology and the abundance of information in all formats that require all individuals using it to poses information literacy skills (ILS).ILS enable people the ability to locate, analyse, evaluate access and retrieve the desired information to satisfy a need. Research on IL in academic and school libraries has gained momentum in the field of Information Science where as little has been documented concerning public libraries and IL. This therefore calls for more research on IL in public libraries. Public libraries serve a wide and diverse community of which students are a part. In instances where school libraries are either non-existent or not developed, students seek assistance from the public library within their community. This study sought to investigate the role of public libraries in enhancing the ILS of senior secondary school students in the Central District in Botswana. The fact that school libraries in Botswana are underdeveloped to produce competent and confident students equipped with ILS that could be used in the work environment and continuous lifelong learning, motivated the study. A concern that there exists a gap in research concerning public libraries and IL within the Botswana context necessitated this study. The study used a survey research design where both quantitative and qualitative research approaches were adopted. This involved the collection and analysis of quantitative and qualitative data. The purpose of a mixed methods approach was based on the idea that qualitative results could assist in explaining and interpreting the findings of a quantitative study. Data collection involved three sets of closed ended questionnaires and observations in all schools and public libraries. The population of the study consisted of public librarians, teacher librarians and students. Quantitative data were analysed using the Statistical Packages for Social Sciences (SPSS) to generate statistics. The findings of the study revealed that the public libraries in the Central District in Botswana are above average in terms of materials and use. It brought to light that senior secondary schoolstudents use the public libraries for school purposes and get assistance when they seek for it. Public librarians do not have special classes aimed at enhancing the ILS of students. The public libraries offer IL in the form of computer training, they do this as, and when students register, just like the other members of the community. The library’s contribution to enhancement of the students’ ILS, (study skills, reading skills and use of reference works) is somewhat limited. Limited resources, lack of reading culture, low budgets, and lack of support from government negatively challenge the full potential impact of IL enhancement. / Information Science / M.A. Information Science

The study examines the dynamic relationship between financial development and investment in three Southern African countries (Botswana, South Africa and Mauritius) during the period 1976 – 2014 using annual data. The motivation for selecting these countries is mainly based on their different characteristics in their economic and financial structure. Employing the Autoregressive Distributed Lag (ARDL) bounds test approach, the study examines the role of financial development in boosting investment; and the causal relationship between financial development and investment. The study makes use of composite financial development indices and divides financial development into bank-based and market-based financial development. In addition, both the impact of bank- and market-based financial development on investment, on the one hand; and the causality between bank- and market-based financial development and investment, on the other, were examined within the flexible accelerator model/framework. For both models, both bank-based and market-based financial development are assumed as having an accelerator-enhancing effect on investment. Empirical results show that, for Botswana, the impact of bank-based financial development on investment is positive in both the short run and the long run while no impact of market-based financial development is found for both periods. For South Africa, the effect of bank-based financial development on investment is found to be negative in the short run and has no impact in the long run. However, market-based financial development has only a positive effect on investment in the long run. For Mauritius, market-based financial development is the only type of financial development found to have a significant positive effect on investment, and only, in the short run. The results of the causality test show that: for Mauritius, both bank-based and market-based financial development tend to drive investment, both in the short run and in the long run; while- in South Africa, investment drives both bank-based and market-based financial development only in the short run. In Botswana, bank-based and market-based financial development and investment drive each other in the short run while investment tends to only drive bank-based financial development in the long run. Therefore, all three countries show differing results and tend to confirm that there are inter-country differences that determine the relationship between investment and financial development. The inter-country differences maybe as a result of the different stages of financial and economic development for each country. / Economics / D. Phil. (Economics)

The Okavango Delta is an extremely dynamic system with variable vegetation comprised of permanent swamps, seasonal swamps, dry islands, floodplains and dry grassland, savanna and woodland. The system is largely driven by the interaction between fire and the annual flood, which filters down from the Okavango River catchments in Angola. While extensive research has been conducted on the flood-driven vegetation little is known about the dry woodland and savanna regions bordering these flood-driven habitats. A taxonomic classification of woody species composition resulted in eleven vegetation types. These data were then reanalyzed in terms of woody species morphology allowing these eleven vegetation types to be grouped into four functional response groups in order to provide a platform for improving the understanding of how dry woodland and savannas interact with the environment. These four groups were the savanna group mixed thornveld and the three woodland groups; mixed broadleaf woodland, shrub mopane woodland and tall mopane woodland. Burning in mixed thornveld and mixed broadleaf woodland was found to decrease woody species density and grass fuel loads and could be used for grazing management to remove unpalatable growth and improve grass species composition, while burning in shrub mopane woodland and mixed mopane woodland merely decreased the woody understory and is not recommended. Utilization dominated by grazing livestock resulted in overutilization of the grass sward leading to bush encroachment in both mixed thornveld and shrub mopane woodland, while utilization by goats alone resulted in underutilization of the grass sward and a dominance of herbaceous annuals. Livestock utilization had no effect on the occurrence of Pecheul-loeschea leubnitziae, a shrubby pioneer previously thought to be an indicator of overgrazing, however extensive P. leubnitziae cover was associated with a sward dominated by shade-tolerant grasses with low forage quality. Shrub mopane woodland and tall mopane woodland appear to be more stable vegetation states than mixed broadleaf woodland and mixed thornveld being less vulnerable to colonization by pioneer species and alteration as a result of utilization or environmental factors. For this reason management and monitoring of mixed thornveld and mixed broadleaf woodland is essential to prevent vegetation degradation and to ensure optimal forage availability for both livestock and wildlife. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2012.

African copper PLC’s flagship is the copper producing Mowana mine located 129 km from Francistown in the North-Eastern part of the Republic of Botswana. The processing operation at Mowana is a standard flotation plant designed to produce copper concentrates from oxide, supergene, and sulphide ores. The expected average output of 16.2 tons per hour of copper concentrates has never been attained since plant commissioning. The major bottleneck has been established to be located around the crushing circuit of the Mowana production chain. The major hypotheses of this research are that performance in a crushing plant is adversely influenced by moderate and discrete changes in the process. The ultimate objective is to develop a dynamic process simulator, administered in Simulink/MATLAB® background, for application in the design of a control model utilising two crusher variables and a self-tuning control algorithm. In this research work, a process model describing the dynamic operation of an Osborn 57S gyrasphere cone crusher is investigated. Modelling of the Mowana crushing circuit is carried out by combining the steady-state and dynamic components of the crushing equipment in the Simulink/Matlab® environment. Eccentric speed (ES) and closed-side setting (CSS) are amongst the important inputs to the models. The rest of the inputs (crusher power, crusher cavity level, federate, pulley diameters, liner wear measurement, number of teeth of the pinion and bevel gear) are extracted from the data collected across the Mowana mine crushing circuit. While it has been demonstrated that the crusher CSS is the most influential controllable parameter, it has also been demonstrated that crusher capacity and power can be used effectively to optimise the circuit. The use of crushing power and cavity level control is suitable for the crushing circuit since the crushers are running on a constant ES and the CSS is set and reset manually. The outcome of the study presents an insight into the optimization of the Mowana mine crushing circuit through the design of a self-tuning controller for the cone crusher and for prototyping, parameters of a PID controller were determined in the Simulink/MATLAB® environment. The simulation involved the optimisation of the control model as a function of the cavity level of and the power drawn by the cone crusher. A self-tuning control algorithm at PLC and SCADA level of control was then tested. This formed the simulations and training platform. The outcome of the simulations carried out in this research needs to be validated against the real Mowana crushing process control upgrade. This will then inform the modifications and recommended crusher motor resizing exercise to be implemented. / Electrical and Mining Engineering / M. Tech. (Engineering: Electrical)
