The purpose of this study was to investigate how knowledge retention may be enhanced at the University of Zambia (UNZA). A mixed research methodology was employed in the case study design. Data was collected using interviews and questionnaires. Purposive sampling was used to determine participants for the interviews while stratified random sampling was employed for the questionnaire respondents. Out of a population of 435 a sample of 205 was surveyed. The response rate was 60 %. Findings indicate that UNZA lacked a number of knowledge retention practices that can enable it to retain operational relevant knowledge. In view of these findings, the study concluded by recommending guidelines for the adoption of various knowledge retention practices that could be embedded into UNZA's knowledge management policy. / Information Science / M.A. (Information Science)

This thesis investigates policy formulation and implementation processes in Zambia. A number of issues emerge with respect to the weaknesses of the system and how policy decisions worsened Zambia's economic performance instead of improving it. The Kaunda era policies of nationalization had an adverse impact on productivity of industries as well as affecting the resource flow from donors and business houses. On the other hand President Chiluba's reforms in the 1990s have had both positive and negative impacts on the people of Zambia. The rapid privatization and liberalization affected employment levels thereby worsening the poverty levels. Further, the liberalization brought in stiff competition from other countries forcing most manufacturing companies to close down. The policy environment based on the Bretton Woods Institutions seems not to be working as result of not taking into account the local Zambian situation. On the other hand, there were positive macroeconomic developments such as growth in GDP, lowering of inflation and stabilizing of exchange rates as from 1996. This has however not improved the living standards of the people. In Zambia, the shifts back and forth between strong and weak planning institutions have negatively affected policy development and implementation. There has been uncoordinated policy development; as a result, some policies in the major sectors are contradictory while in other cases policies are not linked to the resource envelope, making them un-implementable. Secondly, the institutional framework for policy development is not effective. There is generally lack of coordination among ministries, provinces and other stakeholders in planning, implementation and monitoring and evaluation of development programmes. This thesis urges that the improving planning capacities at the national, provincial and district levels should improve the processes of policy development and implementation in Zambia, which will in turn help to reduce poverty. Further, the districts should be the centre for the bottom-up process. In order to carryout this responsibility, efforts should be made to improve their capacities. As for the top-down process, the Sector Advisory Groups should continue to participate in the planning, monitoring and evaluation so as to contribute to policy formulation and implementation. These should be coordinated by the National Development Coordinating Committee (NDCC) through a Planning Bureau. / Development Studies / D. Litt. et Phil. (Development Studies)

The purpose of the study was to determine the factors that predict women’s risky sexual behaviour and HIV and AIDS knowledge. A quasi-experimental, pre-test-post-test research design, with a non-equivalent comparison group was conducted to determine if there was an association between young women’s sexual behaviour and HIV/AIDS knowledge on aspects of HIV/AIDS transmission and prevention and behaviour change. The study used both quantitative and qualitative approach. Data collection was done using semi-structured interview schedule and focus group discussion guide. The respondents who participated in the study were women between the ages of 15-25 years. Two groups of respondents participated in the study. Women in the quasi-experimental site (N=200) who received the intervention and women in the control site (N=200) who did not receive any intervention. Quantitative data were analysed with the help of a statistician and the Epi Info statistical package was used. Qualitative data obtained from the focus group discussion were analysed using Tesch’s method of analysis. The major inferences drawn from this study are that young women lack knowledge relating to HIV/AIDS and that some young women were engaged in risky sexual behaviours such as having multiple sexual partners and having unprotected sex. The study indicates that peer education strategy has the potential to make an impact on these young women. It has also shown that peer education can play an important role in increasing knowledge and reducing risky sexual behaviour. / Health Studies / D. Litt. et Phil. (Health Studies)

The phenomenon of strategy implementation is crucial to the improvement of learner performance, and to the effectiveness of schools. Literature reveals that research on strategy implementation has received much attention in business studies. However, little attention has been given to it in schools. It is this gap which this study endeavours to fill. The key research questions for this study aimed at garnering evidence on factors that influence strategic plan implementation. In the empirical study, two secondary schools and three education offices were purposively selected. A mixed methods research design was adopted, and in this regard, data was collected using interviews, focus group discussions, document analysis, participant observation and questionnaires. Data was analysed by means of organising, coding and categorising. The main findings of the study are that the factors that affect School Strategic Plans (SSPs) implementation are largely related to education management at all levels. There is also anecdotal evidence that teacher, learner and external stakeholder factors affect the implementation of SSPs. In all these factors, monitoring was the major factor. One recommendation proposes that the education managers at provincial and district levels and implementers at school levels should all be empowered with skills and knowledge on effective strategy implementation. / Educational Leadership and Management / M.

The exotic plant Lantana camara L. has invaded the riparian areas of the Victoria Falls World Heritage Site in Livingstone, southern Zambia, threatening native plant communities which support populations of species of special concern. I trialled the mechanical control method of manual uprooting and 3 different herbicides applied through paint brushing of an imazapyr concentrate at 250g. l¯¹, spraying on cut stumps with metsulfron methyl at 600g.l¯¹, and foliar spraying on re-emergent lantana foliage with glyphosate at a dosage of 166g. l¯¹ in July 2008 in 20 100m2 treatment plots, 5 invaded control plots and 5 uninvaded controls. Follow-up treatments for re-sprouting lantana stumps and emerging seedlings were undertaken in June 2009. I measured effectiveness of the methods using adult lantana mortality in June 2009 and lantana seedling density in the different treatment plots during the follow-up exercise. The cost of the various methods and human labour applied were compared across the four treatments at initial clear and at follow-up. All treatments recorded a high adult lantana mortality rate, though there were no significant differences in lantana adult mortality amongst the treatments. Overall, uprooting had the highest adult mortality, followed by imazapyr, metsulfron and lastly glyphosate. Germination of lantana seedlings after clearing was high for all treatments but with no significant differences occurring between the treatments. Both adult lantana mortality and seedling density were however significantly different from the control. With labour included, chemical costs were far higher relative to uprooting, though uprooting costs were the highest when it came to the follow-up because of the emerging seedlings and some resprouting stumps. The effects of mechanical and chemical treatments on vegetation composition in the cleared areas were also assessed in order to detect any non-target and medium term effects of treatments. Contrary to expectation, none of the chemicals showed any significant effects on vegetation composition in the short and medium-term and no significant differences were found in plant species richness, diversity and seedling density between invaded and uninvaded plots at baseline, in October 2008 and in September 2009. In order to determine potential for unaided vegetation recovery in the riparian areas of the study site after lantana clearing, I conducted an investigation of soil seed banks and seed rain using 60 seed bank samples measuring 1800m³ collected from 30 invaded and uninvaded plots. Using the seedling emergence method, 1, 991 seedlings belonging to 66 species representing 27 families germinated from the seed bank. Sedges (Cyperaceae family) were the most abundant taxa in the seed banks from invaded areas, followed by Ageratum conyzoides, lantana, Triumfetta annua and Achyranthes aspera which also occurred in the uninvaded soil seed banks. The seed banks from uninvaded plots were dominated by the grass Oplismenus hirtellus. Overall, species richness, diversity and seedling density from seed banks in invaded areas did not differ significantly from seed bank in uninvaded areas and there was a low similarity in species composition when above ground vegetation was compared to seed banks from invaded and uninvaded areas. It would appear if natural regeneration occured from the current seed bank in disturbed areas, future vegetation would largely comprise of short lived, early successional species in the short term as the seed bank is dominated by non-native herbaceous weedy species. From the seed traps investigating seed rain, a total of 27 species numbering 623 individual seeds were found in the thirty 1m² seedtraps distributed in invaded and uninvaded areas at the five sites, over an intermittent period of three months. Lantana had the highest monthly arrival rate in the seed traps followed by Phoenix reclinata and Ricinus communis. The number of species with invasive potential found in the seed traps located in invaded areas was more than that found in seed traps under native vegetation cover by far. Considerable forest remnants still occur around the invaded sites, and these could serve as an important source for long-term natural re-establishment of native vegetation if seed availability by animals and wind dispersal continues, while the re-invasion of lantana is prevented by ongoing follow-ups and futher clearing of lantana invaded areas. It is concluded that while uprooting and other treatments are effective in the control of lantana, its successful control in the Victoria Falls World Heritage Site will require extensive clearing to keep it from reinvading infested areas after clearing as shown by the seed rain data. The high seedling density of lantana in the seed banks and in the cleared areas shows the need for ongoing follow-up in order to deplete soil stored seed banks. There is need for longer term research to establish what the exact follow-up requirements are in order to contain lantana re-infestation and create favourable micro-sites for native species to establish. It is predicted that ongoing lantana control in the cleared plots will most likely initiate long-term community recovery.

The Kaponda Prospect represents a surface of 915.8 km² located at about 10 km south of the town of Lubumbashi and 33km NW of Kasumbalesa in the Democratic Republic of Congo (DRC). It lies within Neoproterozoic sedimentary rocks of the Katangan Supergroup in the Central African Copperbelt (CACB). In this province, copper mineralization occurs at different stratigraphic level with different associated alteration. Mineralization is of multistage origin from synsedimentary, diagenetic to post orogenic. Since the discovery of the CACB in the early 20th century, several exploration techniques have been used to delineate Cu deposits. A review and application of these methods including remote sensing, geological mapping, geochemical and geophysical surveys, and drilling, gives an insight of their effectiveness and limitation before analyzing their results from the Kaponda Prospect. The geology and structure of the Prospect is represented by a series of two NW trending disharmonic tight anticlines, locally domal, with cores occupied by either Roan Group or “Grand Conglomerat” Formation. These anticlines are separated by an open syncline made of Kundelungu rocks. Two mains direction of faults are recognized, the NW and NE trending structures. The latter direction are normal transfer faults which can serve as conduit for mineralization. They are related to the late orogenic extension of the Lufilian belt. However NE trending faults are believed to be associated to the climax of Lufilian folding or represents synsedimentary intergrowth faults. Exploration approach for sediment-hosted Cu within Kaponda Prospect, take into account the integration of all information derived from different techniques. Remote sensing is used as aid to geology. Landsat and Google earth images show lineaments that corresponds to lithostratigraphy boundary and domal anticline. Geological mapping identified reduced horizons which can potentially host mineralization, whereas analysis of structure measurements reveals the geometry of fold and direction of its axial plane and hinge. Statistical methods such as the main + 2 standard deviation, the frequency histogram and probability plot, together with experiential method are used to constrain and define Cu and Co thresholds values in soil samples. It appears that in this region, log-probability plot and histogram methods combined with spatial representation and the experience of the region, are the best practice to constrain and separate geochemical background from anomaly data. Ground and airborne magnetic, and radiometric images show specific signatures which map alteration and particularly lithostratigraphy such as “Roan” Group, “Grand Conglomerat” unit, “Nguba” cap carbonates and “Kundelungu” siliciclastic units. Analysis of faults interpreted from geophysical maps identified three major directions: E-W, NE-SW and NW-SE. The E-W faults are also interpreted as normal transfer faults such NE-SW structures, consistent with regional geological map. Although pole-dipole array of induced polarization (IP) survey was directly targeting disseminated Cu sulphide, its results suffer in responding to graphitic rocks and barren pyrite. Only relative small chargeable bodies need to be tested in drilling follow-up. A total of 15 targets have been generated through re-interpretation and integration of both geological mapping and remote sensing, geochemical and geophysical data, as well as existing drilling. Specific recommendations of follow-up works are advised for each type of target.

The purpose of the study was to explore teachers’ views on using mobile laboratories when teaching Integrated Science during science practical lessons; to assess the teachers’ competencies in using the mobile laboratories and the challenges they face in this practice. The research used a survey as a research design. The target population was all teachers teaching Integrated Science. The sample comprised of forty-five (45) respondents from Northern and Eastern provinces of Zambia. Purposive sampling was used to pick the participants of the study. In collecting data, questionnaires, interview schedules and observation checklist were used to collect data needed for this study. The instruments were piloted before they were used in the study. The findings from the study revealed that the quality of material in these laboratories are quite good but their numbers are not in line with the size of the classes, which negatively affects the teaching and learning process of practical lessons in science. Additionally, the teachers’ qualification, was found to be associated with their competence in the use of mobile laboratories; that is, the higher the qualification, the more the competence in the use of mobile laboratories apparatus. Furthermore, the study established the following challenges on the use of the mobile laboratories: inadequate materials in the mobile laboratories, schools are not financially strong to replenish them after they are used up, some teachers find it timeconsuming to prepare and set up the apparatus for experiments and orientation is needed for some teachers on how to use these laboratories. In view of the findings, it is recommended that the government should provide more laboratory materials and monitor the level of usage of these materials. Additionally, short courses should be organised aiming at improving science teachers’ knowledge and skills of the use of mobile laboratory facilities. Moreover, Continuous Professional Development (CPD) must be enhanced in schools with an emphasis on the orientation of mobile laboratories usage by all science teachers. / Science and Technology Education / M.

The quest for epistemic liberation remains an important project in the post-colonial era of Zambia, and entails challenging the existing inequalities in knowledge representation at the epistemic front in the country. At the core of this quest is the position that the continued dominance of Western knowledge and the corresponding marginalisation of indigenous knowledges amount to an epistemic injustice that affects the contemporary existence of the peoples in the country. This study critically examines the problem of epistemic injustice in Zambia while reflecting on the country’s uncompleted project of decolonisation. It traces the problem from the theoretical assumption of modernity that Western knowledge is universal and that it should, therefore, be applied to all societies in the world. It is submitted that the current education system in Zambia is based on this assumption, and, consequently, favours Western knowledge to the exclusion of indigenous knowledges. This practice is identified as a conduit for accelerating epistemic injustice and its intensity in the country. The study approaches this problem from an African philosophical standpoint, and draws its current from the history of the political struggle against domination on the continent. To adequately confront the problem of epistemic injustice in Zambia, the study suggests parity and equilibrium in representation between indigenous knowledges and Western knowledge in the country. / Philosophy, Practical and Systematic Theology / M.A. (Philosophy)

This qualitative study was done in Livingstone, Zambia, and used focus group discussions to investigate the reasons that youths aged 15 to 24 years see as justifying, or compelling, their non-use of recommended methods for prevention of sexual transmission of HIV. It focused on four methods, namely abstinence, condom use, voluntary counseling and testing, and mutual faithfulness. The study found that non-adherence to HIV preventative methods is linked to variables in the process of adolescent growth and development, to contextual variables in society, to characteristics of products and services associated with these HIV preventative methods, and to disease characteristics of HIV itself. A key conclusion of this study is that to improve the effectiveness of HIV prevention programs among the youths it is essential that factors that hinder adherence to preventative methods are recognized and addressed. / Social Work / M.A.(Social Work)

The purpose of this dissertation was to identify factors that contribute to the sustainability of rural water supply facilities (WSFs). Twenty-four interviews were conducted: 16 from rural communities and 8 from water supply agencies. Key findings are that in order to achieve sustainability of WSFs, there is need to ensure that (1) there is an effective community organisation; (2) communities have the ability to operate and maintain WSFs; (3) communities are able to raise adequate user fees for purchasing spare parts; and (4) that there is a strong backup support at the district level to carry out major repairs. Major threats to the sustainability of WSFs include high poverty levels in communities, weak institutional framework and inability of communities to handle major breakdowns. / Social Work / M.A. (Social Work)
