- Description: There has been only limited scholarly analysis of Malawi’s foreign policy since its independence in 1964 with key texts focusing primarily on the early years of the new state. Perhaps due to its relatively small stature – economically, politically and militarily – in the region, very little attention has been paid to the factors informing Malawi’s apparently uncritical foreign policy response to the Zimbabwe crisis since it began in the late 1990s. This thesis addresses this deficit by locating its understanding of Malawi’s contemporary foreign policy towards Zimbabwe in the broader historical and contemporary context of bilateral relations between the two states and the multilateral forum of SADCC and SADC. It is argued that the Malawi’s long-standing quest for socio-economic development has forced it to manoeuvre a pragmatic but sometimes contentious foreign policy path. This was also evident until the end of the Cold War and the concomitant demise of apartheid in South Africa in the early 1990s. Malawi forged deliberate diplomatic and economic relations with the region’s white-ruled Zimbabwe (then Southern Rhodesia) and South Africa in pursuit of its national economic interests while the majority of southern African states collectively sought the liberation of the region by facilitating the independence of Zimbabwe and countering South Africa’s apartheid and regional destabilization policies. In the contemporary era, there has been a convergence of foreign policy ambitions in the region and Malawi now coordinates its regional foreign policy within the framework of SADC, which itself prioritizes the attainment of socio-economic development. However, to understand Malawi’s response to the Zimbabwe crisis only in the context of SADC’s “quiet diplomacy” mediation efforts obscures important historically rooted socioeconomic and political factors that have informed relations between Malawi and Zimbabwe and which cannot, it is argued, be ignored if a holistic understanding of Malawi’s position is to be sought. This study argues that the nature of historical ties between Malawi and Zimbabwe and the role of Malawi’s leaders in driving its long-standing quest for socioeconomic development have not only informed its overall foreign policy behaviour in the region but underpin its contemporary relations with Zimbabwe.

- Description: This study investigates parental involvement in school governance in selected high schools in Zwelitsha, King Williams Town District in the Eastern Cape Province. The research study was conducted in three high schools in Zwelitsha Township. These schools are Nompendulo Senior Secondary, Thembalabantu High School and Xolani Senior Secondary School. Questionnaires were designed and distributed to the principals, educators and parents whose children are learners in these schools. The interview questions were designed and distributed to parents whose children are learners in these selected schools, educators and school principals and members of the school governing body from each school. Respondents were asked about the levels of parental involvement in their schools, parents’ awareness of school governance and the relationship between schools and communities. However, the objectives of the study were to: Assess parental involvement in school governance in selected high schools in Zwelitsha, King Williams Town District in the Province of the Eastern Cape; To determine the nature and extent of parental participation in school academic activities; To examine the role of parents in the school governing body; To determine measures that can be taken to encourage the participation of parents in school governance These objectives have been achieved by providing empirical evidences which shows that the levels of parental involvement in the previously disadvantaged high schools are very low. This is related to the parents’ level of education. Parents who are literate are more involved than those are illiterate. This research also reveals that high v. levels of working parents contributes to the low levels of parental involvement in school governance. Most parents in this area know nothing about school governance and those that are aware are not keen to be involved. The class structure of the society has an influence in the participation of parents in school governance. Parents’ meetings that are held on Sunday afternoon are a challenge to parents that come from the villages outside Zwelitsha because of the scarcity of transport on this day. and these situations discourage them from being actively involved in their children’s education. The study provides the factors that cause non-involvement of parents in school governance. Subsequently, the following strategies for participation of parents in school governance were given: Capacitating of parents Establishment of teacher-parent collegiality Recognition of cultural capital Establishment of parent organisations Utilisation of non-governmental organisations Establishment of centres of learning. This study also indicates the following strategies that may assist to enhance the parental involvement in school governance: Parents engagement and empowerment Co-operation between schools and parents Collaboration with other community, private and other public institutions Invitation of complaints and welcoming of criticism. In conclusion, the findings provide clear indication that the participation of parents in school governance is low. Recommendations that could assist the schools to encourage and to enhance parents to participate in school governance are given.

- Description: Rural-urban migration appears to be an ongoing process in South Africa. This is attributed to various reasons. In itself, the process contributes towards an ongoing demand for services such as housing, water, sanitation and transportation systems. Rural – urban migration plays a key role in urbanization. The living conditions in rural areas appear to be the main contributing factors towards rural-urban migration. This indicates that the challenges facing rural communities include the creation of conducive environments within those communities. Hence, the issue of rural-urban migration should be addressed from the spatial and socio – economic perspectives. In an attempt to address human settlements needs, South Africa has a policy framework which supports the right to housing as it has been accorded to South African citizens by their Constitution. The objective is to ensure that there is adequate housing for South Africans. This study investigated and analysed the relationship between rural-urban migration and housing delivery in Clermont Township in the Province of KwaZulu-Natal. The participants included the residents of Clermont Township and the representatives of the eThekwini Municipality. Among others, the study found that rural-urban migration is an ongoing process which affects housing delivery in urban areas. As a result it continues to make the objective of ensuring that there is adequate housing for South Africans unattainable. Hence, attention should be paid to the effects of rural-urban migration in housing delivery.

- Description: The aim of this research was to understand the main factors that explain turnover and retention at DOA Ukhahlamba District and to recommend to the District and Provincial management the appropriate strategy for retaining staff. To be able to achieve this aim, the following research objectives have been visited, namely: a) turnover trends, b) analysis of primary and external turnover factors and c) primarily retention factors. Data for analysing turnover trends was collected from the 2004 to 2007 DPSA and DOA annual reports. Primary data on labour turnover and retention factors was collected from 41 employees across different sections at DOA Ukhahlamba District by means of a questionnaire survey. The data was analysed using statistical methods, including frequency distribution, chi-square test and Pearson product-moment correlation. The findings have revealed that there is no clear pattern of turnover trends at DOA and DPSA, and DOA percentage turnover figures are low in comparison with those of the DPSA. In terms of organizational-specific factors, the top three primary turnover factors were identified, namely: a) communication within the organisation, b) leadership and the organisation and participation in decision making. The research results further revealed that communication within the organization had a significant impact with regard to race, but division, location, and grades did not. With regard to the external factors, research results identified the following most important external labour turnover factors arranged according to their importance, namely: lack of availability and quality of health care services and infrastructural development; lack of available sport and recreation facilities; crime in the area and people living in the neighbourhood; lack of educational opportunities available for the family, and geographic location of place of employment. The findings further revealed the top three retention factors, were strongly significantly correlated to each other, namely: resource availability, use of discretion in handling customer complaints, and the impact of the job on society. These are positively related to intention to stay. The implications these results to the management would require the review of the organisational Human Resource Management Policy and the introduction of Attraction and Retention Policy because at present its is non existence at DOA Eastern Cape. Research limitations: the study did not fully explore ethnicity when analysing the communication within the organisation as a labour turnover factor despite having an organisation that is diverse in nature, future academic research should focus more on labour turnover at management level and moderating variables to external labour turnover factors as there is little research done in this area. The factors identified for labour turnover and retention should be treated with caution as it may not be applicable to all sector Departments in the Eastern Cape and may be limited to Ukhahlamba District due to its geographic location. This study will contribute to the body of knowledge as it will serve as a guide to Eastern Cape DOA and other sector Departments in choosing factors to consider when designing their retention strategy in order to reduce labour turnover. To the academic researchers, the first three primary retention factors identified in the survey have not been seen before, grouped and rated amongst the top three retention factors which therefore means that the management support becomes more important than looking more on salary package as the first priority factor as revealed by most of the research literature consulted (Gustafson, 2002; Mobley, 1982; Mobley, 1979; Herzberg, 2003). This shows that labour turnover and retention factors will not be the same to all organisations, the location of the business and surrounding environment should be considered carefully when designing the appropriate policy and retention strategy of the organisation.

- Description: The extensive amount of research conducted internationally in the field of John Bowlby's attachment theory indicates that an insecure attachment between a child and the primary caregiver has a detrimental effect on both social and emotional development in childhood, as well as having a profound effect on psychological development and functioning in adulthood. The present study aimed to explore and describe the therapeutic process of a nine year old with an insecure attachment style within a therapeutic framework, namely Theraplay. The therapeutic process was embedded within Ann Jernberg's Theraplay framework and the case was further contextualized within Bowlby's attachment theory. The case study method was utilized with a purposive sampling technique employed to select the participant. Irving Alexander's content-analytic framework in conjunction with Guba's model of trustworthiness was employed for data analysis. Two needs emerged during the therapeutic process namely the need for nurturance and affection as well as the need for power, control and safety.

- Description: Family businesses constitute between forty five and ninety percent of gross domestic product world wide. Research shows that within the next five years over fifty percent of executives will retire, highlighting the significance of successful family business successions. Family businesses founded in the “baby-boom” era are of immediate concern to researchers who are working to understand the dynamics around the succession process and ultimately the criteria preventing or enhancing successful successions. The purpose of this study was to better understand the development of successors in family businesses. A detailed literature study was conducted on family businesses and in particular the factors which both positively and negatively affect family business successions. A single case study approach was used to test whether six dynamic variables applied to this case or not. Three sibling brother successors, a sibling sister and their parents were each separately interviewed and the interviews voice recorded. They were asked questions which could be later analysed and used to uphold or negate whether the six dynamic variables applicable to successful family business succession were upheld or rejected. The data was meticulously analysed and similar answers grouped together. Answers which varied from the norm were reported separately. It was found that in all six of the propositions the responses received from the case study respondents upheld the propositions. Thus, families businesses seeking succession, may well understand and take action regarding the six dynamic variables relating to successful family business successions

- Description: This research study has emerged as a result of my concern regarding the apparent low self-efficacy amongst initial teacher education students in my mathematics education classes. It also reflects a reported renewed interest in values, and the promotion of excellence in education. The effects of a values-based approach to mathematics education towards improving students’ self-efficacy and promoting excellence have been investigated, grounded within my ontology of excellence in mathematics education, which incorporates the values of respect, fairness, accountability, honesty and compassion. An inquiry-based teaching and learning approach formed the framework within which the study took place. Notions of ‘new scholarship’, premised on the view that teaching is about engagement in participatory learning, and the development of communities of creative students, provided the theoretical framework. Both quantitative and qualitative data gathering methods were used. Data-collection tools included affective-disposition statements, interviews, journal entries, as well as a video recording of a mathematics education lesson. The quantitative and qualitative data generated suggest improved levels of self-efficacy amongst the students who participated in the study. The data also suggest that a valuesbased approach to teaching can be used as an effective approach by mathematics teachers – and mathematics teacher educators – for the purpose of promoting the pursuit of excellence. As teacher education worldwide is currently characterised by a lack of vitality in teacher preparation (Grossman, 2008), the findings of this study should provide insights for teacher educators, teachers and policy makers who wish to promote mathematics self-efficacy, excellence and facilitate enhanced vitality within the teaching profession.

- Description: This research study has emerged as a result of my concern regarding the apparent low self-efficacy amongst initial teacher education students in my mathematics education classes. It also reflects a reported renewed interest in values, and the promotion of excellence in education. The effects of a values-based approach to mathematics education towards improving students’ self-efficacy and promoting excellence have been investigated, grounded within my ontology of excellence in mathematics education, which incorporates the values of respect, fairness, accountability, honesty and compassion. An inquiry-based teaching and learning approach formed the framework within which the study took place. Notions of ‘new scholarship’, premised on the view that teaching is about engagement in participatory learning, and the development of communities of creative students, provided the theoretical framework. Both quantitative and qualitative data gathering methods were used. Data-collection tools included affective-disposition statements, interviews, journal entries, as well as a video recording of a mathematics education lesson. The quantitative and qualitative data generated suggest improved levels of self-efficacy amongst the students who participated in the study. The data also suggest that a valuesbased approach to teaching can be used as an effective approach by mathematics teachers – and mathematics teacher educators – for the purpose of promoting the pursuit of excellence. As teacher education worldwide is currently characterised by a lack of vitality in teacher preparation (Grossman, 2008), the findings of this study should provide insights for teacher educators, teachers and policy makers who wish to promote mathematics self-efficacy, excellence and facilitate enhanced vitality within the teaching profession.

- Description: Debarking of Acacia mearnsii in South Africa has been conducted using mainly manual systems. Labour shortages and reliability of these systems has caused interest in alternative systems that might be able to debark A. mearnsii. The aim of the research is to compare three mechanised debarking technologies used to debark A. mearnsii. Research trials were conducted on the Demuth, Hyena and Hypro debarkers that would form part of semi-mechanised harvesting systems. The debarking technologies were analysed and compared in terms of productivity per productive machine hour (PMH), debarking quality, system costs and the quality of the bark that was produced. Furthermore, the effect that tree volume, strippability and form have on each of the debarking technologies was determined. The debarking technologies were affected by each of the factors researched. Decreasing tree form had a negative effect on the productivity of each of the technologies. An increase in strippability class (strengthening wood-bark bond strength) caused a decrease in the productivity of each of the machines. An increasing tree volume had a positive effect on the productivity for the three debarking technologies. After the debarking had taken place, samples of bark were analysed at a laboratory to determine if it was acceptable for the processing facilities. Each of the debarking technologies produced bark of varying dimensions, but they were all found to be acceptable. The system costs of the three debarking technologies were compared to a manual system cost at tree volumes of 0.1m³, 0.15m³ and 0.2m³. The Demuth debarker had the best system cost for a tree size of 0.1m³, while the manual system was best for tree volumes 0.15m³ and 0.2m³. The Demuth, Hyena and manual system costs were very similar for each of the tree volumes, with the Hypro being a little higher.

- Description: Throughout the world, but especially in the African continent, international, cross-border and national conflicts are ongoing. In the majority of these conflicts child soldiers are involved in various ways. Judicial problems concerning the prosecution of commanders and leaders of armed groups, irrespective of governmental or not are being solved. Thus, underlying concern is left to the issue of accountability of child soldiers. International, Regional and National protection measures provide for certain judicial standards dealing with children under the age of eighteen. In order to fully understand the difficulties arising from the existence of universal binding measurement dealing with the accountability of child soldiers, one has to be aware of the international, regional and national legislative frameworks. In Sub Saharan Africa, especially in Rwanda, Uganda and the Democratic Republic of Congo, governments face various difficulties, such as the implantation process of international protection measures and ongoing conflicts, making it very difficult to examine the status of accountability measures for child soldiers. States have different minimum ages for accountability for child soldiers. Only a process of international co-operation between governments and non state actors can attempt to deal with the accountability of child soldiers. Not only deterrent, but rather restitution approaches and reintegration programmes should be followed in order to bring justice and achieve results in peace processes.

- Description: In this thesis I argue that the tradition of political philosophy which follows in John Rawls's footsteps is obligated to concern itself not only with the realizability, but also with the realization, of justice. Although Rawls himself expresses a commitment only to the former of these, I argue that the roles which he assigns to political philosophy require him to take on the further commitment to realization. This is because these roles are meant to influence not only political philosophers, but the citizens of the wider community as well. The realistically utopian role, which I take to be the central one, requires political philosophy to inspire in that population a hope which I argue that realizability alone cannot provide. Given the deep revisions regarding the political nature of justice as fairness which Rawls made on the basis of realizability concerns, I argue that his theory must in this case be committed to a similar revision. The hope which political philosophy is meant to provide is simply not realizable until the discipline concerns itself centrally with the task of realization.

- Description: Children are placed in a children’s home when a Presiding Officer finds them to be in need of care and when there is no viable community placement alternative. The body of literature on children’s homes focuses primarily on the negative effects and outcomes of such statutory placement. The assertion that children who grew up in children’s homes will continue to use the services of welfare organisations in adulthood, is supported by the researcher’s observation as a practicing social worker. This, and the study of available literature, resulted in this qualitative, exploratory-descriptive and contextual research study with the following goal: to enhance the understanding of how intervention programmes at children’s homes can contribute to adult adjustment and independent functioning of those children in their care. A purposive sampling method was used to identify ten participants who had spent at least 2 years in a children’s home and who had been discharged from the children’s home at least 5 years ago (to the date of data collection). The sample was drawn from clients at non governmental social welfare agencies who fitted the sampling criteria. The data was collected via semi-structured interviews using an interview guide, which were recorded, transcribed and then analysed using a thematic content analysis approach. The results of the study may be used to develop and implement meaningful intervention strategies for individuals placed in children’s homes.

- Description: Bolted connections where used from the beginning of vehicle construction for joining two or more parts. The reliability of bolted connections is still a major problem. The objective of this research thesis is focused on an advanced monitoring system for bolted connections in vehicle construction. A mechanical “vibrating test bench”, which was developed by the aeronautical engineer Mr. Junkers, is being adapted, to suite the requirements of the automotive industry. It is designed according to DIN 65151 standards. The bolted connection is tightened to a specific torque to achieve the required preload forces and then exposed to an oscillating elastic shear force. The preload force and their loss are measured in relation to the number of load cycles. The ideal locking mechanism would be, if no settling occurs. Realistic in practice is the remaining of a sufficient preload force which doesn’t decry with time. The aim of this thesis is, to gain knowledge that will assist in the future control of the bolt locking procedure. The test bench can be used to verify the clamping capability of a bolted connection. With the dynamic computer-aided test system it will also be possible to test critical bolted joints and their safety, which reduces the probability of costly product recalls, or even severe cases of failure.

- Description: The topic of this thesis is aerial optical fibres in telecommunication systems: state of polarization (SOP) and polarization mode dispersion (PMD) monitoring and tolerance of modulation formats. Errors in optical fibre telecommunication systems are introduced when these polarization effects (SOP and PMD) change. These changes are so intense especially in aerial optical fibres. Part of the backbone of South Africa’s national grid includes long distances of aerial optical fibre between transmission exchange stations. The work in this thesis can be divided into three parts which all deal with the major aspects of PMD in deployed aerial optical fibres: characterization, environmental effects plus other perturbations, and tolerance of different modulation formats. In our work, SOP and PMD field measurements revealed that they both fluctuate more rapidly in deployed aerial optical fibres especially on windy and hot days. The SOP and PMD changes in the aerial optical fibres showed a significant correlation with these environmental parameters. SOP and PMD are stochastic in nature due to changes in the properties of the optical fibres and its positions because of both intrinsic and extrinsic perturbations. In our work, with only 184 PMD values measured and obtained by use of the FTB-5700 single-ended dispersion analyzer, the predicted theoretical Gaussian fit was obtained with a mean of 0.47 ps and standard deviation of 0.08 ps. This small standard deviation was justification for its robustness and accuracy. The statistical distributions for first-order polarization mode dispersion (FO-PMD) and second-order polarization mode dispersion (SO-PMD) for the first time were experimentally confirmed when measured using the FTB-5700 single-ended dispersion analyzer instrument for deployed aerial optical fibres. We were also able to determine the time scale over which to compensate FO-PMD in deployed aerial fibres using the directional time drift autocorrelation function method. It is slightly higher than 390 s for SOP measurements made on a particular windy and hot day. This is due to the fact that the changes of the PMD vector are known to be slower than the SOP changes. vi We also investigated the theoretical statistical distribution that corresponds to output SOP variations. The SOP variations can either be with wavelength (for buried fibre) or with time (for aerial fibre). Our results showed that the statistics of the relative SOP changes approached the distribution proposed by Foschini et al. (2000). Advanced optical modulation formats have become a key ingredient in the design of modern state-of-the-art wavelength-division-multiplexed (WDM) optical transmission systems. In our work, we investigated which of these advanced modulation formats is best suited for the South African network especially on systems that have links of aerial optical fibres. Keywords: aerial optical fibre, polarization mode dispersion (PMD), principal states of polarization (PSP), state of polarization (SOP), first-order PMD, second-order PMD.

- Description: A cardinal development goal of the Zimbabwean government is agricultural mechanization through the acquisition and use of tractors by arable crop farmers in communal and resettlement state land. This research project therefore aimed at investigating the impact of mechanization on agricultural productivity focusing on farmers in Bindura district of Zimbabwe who benefitted under the ongoing farm mechanization program. The existing land policy and the issue of technical efficiency in agricultural productivity are assumed to be the drivers of the program. It is likely that these key issues will constitute an important consideration in determining the sustainability of the mechanization policy. A multistage sampling technique was used to randomly select 90 farmers in the study area. The Cobb Douglas approach and Logistic regression were used to analyze data obtained from the respondents. Results revealed that tractor use was positively influenced by household size, access to extension services and crop output equivalent. Education, land area cultivated, stoniness negatively influenced the probability of adoption of mechanized farming. Furthermore, the technical efficiency estimate of adopter and nonadopters of mechanized farming showed no difference in their level of technical efficiency in agricultural productivity that was 64 percent on average. The level of observed inefficiency was increased by slope, stoniness and household size while age reduced technical inefficiency. It is recommended that government should consolidate the present gains arising from extension services. Also, environmental factors such as slope (topography) and stoniness, which constituted major disincentives in communal areas, could be overcome if government and farmers can identify and open up new areas of farmland for occupation by farmers.

- Description: It is largely believed that decentralisation promotes efficiency in organisations. This paper analyses the challenges facing decentralisation of Sector Education and Training Authorities (SETAs) in the Province of the Eastern Cape. It is demonstrated that the form of decentralisation followed by SETAs in the Province of the Eastern Cape, where constant referral of matters to head offices for decisions and instruction before any action is taken, by them is the biggest challenge. Yet these important institutions are mandated by government to equip South Africans with skills to enable them to succeed in the global market and to offer opportunities to individuals and communities for self advancement and to play a productive role in society are frustrated by unnecessary interference from SETA national offices on their affairs at the provincial government level, which constrains effective decentralisation. However, the objectives of the study are to: - Analyse the challenges of decentralisation by SETAs in the Province of the Eastern Cape; - Provide an overview of the impact of SETA provincial offices on requisite skills in the province; - Investigate the advantages and disadvantages of decentralising SETAs in the provinces. These objectives have been achieved by providing empirical evidence as indicated in chapter four, where it shows that participants believe that decentralisation promotes efficiency and SETAs in the Province of the Eastern Cape are not granted discretionary powers to make decisions a primary reason that leads to delays being experienced. This lack of discretionary power is proof that decision-making is still centralised. The study has the following strategies for the SETAs in the Province of the Eastern Cape to carry out their skills development mandate: - Clear strategic intent about SETA provincial offices; - Sector Skills Plans (SSP) to reflect provincial focus; - Provincial offices to exercise some discretionary powers; - Adequate financial resources; - Skilled workforce. In order to be more effective and efficient, a variety of recommendations to SETAs, with respect to decentralisation of SETAs, were made. It is hoped that these recommendations assist in improvement of the implementation of a decentralisation strategy. More importantly decentralisation of SETAs should allow and enable branch offices to exercise discretionary powers. In addition, they should have adequate financial resources to manage their affairs.

- Description: It is largely believed that decentralisation promotes efficiency in organisations. This paper analyses the challenges facing decentralisation of Sector Education and Training Authorities (SETAs) in the Province of the Eastern Cape. It is demonstrated that the form of decentralisation followed by SETAs in the Province of the Eastern Cape, where constant referral of matters to head offices for decisions and instruction before any action is taken, by them is the biggest challenge. Yet these important institutions are mandated by government to equip South Africans with skills to enable them to succeed in the global market and to offer opportunities to individuals and communities for self advancement and to play a productive role in society are frustrated by unnecessary interference from SETA national offices on their affairs at the provincial government level, which constrains effective decentralisation. However, the objectives of the study are to: - Analyse the challenges of decentralisation by SETAs in the Province of the Eastern Cape; - Provide an overview of the impact of SETA provincial offices on requisite skills in the province; - Investigate the advantages and disadvantages of decentralising SETAs in the provinces. These objectives have been achieved by providing empirical evidence as indicated in chapter four, where it shows that participants believe that decentralisation promotes efficiency and SETAs in the Province of the Eastern Cape are not granted discretionary powers to make decisions a primary reason that leads to delays being experienced. This lack of discretionary power is proof that decision-making is still centralised. The study has the following strategies for the SETAs in the Province of the Eastern Cape to carry out their skills development mandate: - Clear strategic intent about SETA provincial offices; - Sector Skills Plans (SSP) to reflect provincial focus; - Provincial offices to exercise some discretionary powers; - Adequate financial resources; - Skilled workforce. In order to be more effective and efficient, a variety of recommendations to SETAs, with respect to decentralisation of SETAs, were made. It is hoped that these recommendations assist in improvement of the implementation of a decentralisation strategy. More importantly decentralisation of SETAs should allow and enable branch offices to exercise discretionary powers. In addition, they should have adequate financial resources to manage their affairs.

- Description: The fast track land reform programme resulted in a fundamental reorganisation of rural relations in Zimbabwe, changing the landscape in an irreversible way with people from diverse backgrounds converging on former white-owned farms. This thesis tells the story of how the newly resettled land beneficiaries are organising themselves socially in response to various economic challenges. It makes a contribution towards understanding how redistributive land reforms and local government restructuring influence rural social organisation and agency. Furthermore the study examines local perceptions on the meanings of the „farm‟ and „land redistribution‟. An utterance by one war veteran “what used to be your farm is now our land and you are free to take your farm but leave our land” provides an alternative rendition to contestations of restitution versus a purely farm productionist discourse. The study, through an analysis of primary and secondary data, provides a fresh understanding of the social outcomes of fast track. It traces the evolution of land and agrarian reforms in post-independence Zimbabwe and the political and social economic context that led to „fast track‟. Through an analysis of field findings the thesis is able to define the dominant social groups that were resettled during fast track and the challenges they face in utilising the land. The findings show that the majority of the land beneficiaries were from the customary areas, with limited agricultural experiences. Local cooperation within informal networks and local farmer groups has been identified as one of the ways in which social reproduction is being organised. These groups are responsible for enhancing production capacity but they face a number of constraints. The study derives its theoretical foundation from the post 1980s debates on rural society dominated by Mafeje (1993, 2003), Rahmato (1991) and Mamdani (1996). The debates centred on how institutions of inclusion, authority and cooperation such as the lineage groups, local farmer groups and traditional authority remain relevant in the organisation of post-independent rural African society especially in a context of increased commoditisation of rural relations of production. Using theoretical insights derived from analysing the role of the lineage groups in the allocation of critical resources such as land and the influence of traditional authority (indirect rule) as a form of local government, the study examines how social organisation is emerging in areas where neither lineage nor traditional authority are not dominant. The thesis of rural cooperation through local groups as advanced by Rahmato (1991) and Moyo (2002) provides partial insights into the response mechanisms that land beneficiaries invoke in this instance. It is not necessarily an autonomous space of organisation but rather the state is actively involved through various functionaries including extension officers who invariably advance a very productionist approach. The state‟s monopoly through its local functionaries hides its political cooptation effect by emphasising organisation for production without questioning the manner in which that production is externally controlled through limited rights over land, the state‟s monopoly over inputs supply and markets for commodities. Whilst land reform has been driven by local participation through land occupations, local government reform has been technocratically determined through Ministerial directives. There is however little innovation in the form of local government that is being introduced. It expands the fusion of authority between elected Rural District Councils and unelected traditional authority functionaries. The forms of social organisation and agency that have emerged remain subordinated to the state with no links to other networks of rural producers‟ associations and urban civil society organisations. These developments form part of a longheld tradition within the Zimbabwean state where the legitimacy of local organisation and authority is usurped to service the interests of the state. Thus whilst land reform has to a certain extent accommodated the majority poor, the ensuing local government and agrarian reforms are more focused on limiting their participation in broader processes of political engagement around distribution and accumulation and their own governance.

- Description: In 1994, democracy in South Africa brought about a developmental local government characterized by democratic and accountable governance. Municipalities are supposed to encourage the involvement of communities and community organizations in the matters of local government. Municipalities are obliged to establish ward committees and ensure that they succeed in facilitating public participation. However, critiques contend that ward committees have not been able to live up to expectations. The institution is said to be faced by countless challenges that inhibit its functioning. This study has, therefore, been undertaken with the purpose of analyzing the factors that affect the performance of ward committees in the Buffalo City Municipality. The research found that ward committees in the municipality were properly constituted, functional and handle serious issues for the benefit of communities. Communities are not very interested in ward committee meetings and do not solicit assistance from them. Based on the results of this study, the following are the factors which compromise and limit the ability of ward committees to facilitate public participation: lack of remuneration, low levels of education and skills, unavailability of information on municipal issues and activities; and a lack of municipal support. Following the research, it is recommended that municipalities put in stringent measures to detect and curb corrupt practices in ward committees. On annual basis they should provide a meaningful budget allocation for the remuneration and provision of facilities and equipment necessary for ward committees to effect public participation. Municipalities should involve ward committees in decision-making

- Description: Groundwater resources is the major source of potable water in Mchinji District of Central Malawi and globally. Although the total amount of water on and under the earth‟s surface is generally assumed to have remained constant, the rapid population boom coupled with extension of agricultural farmland and industrial development are putting pressure and stress on the quality and quantity of water resources. In principal therefore, „use and discard‟ philosophy in water resources cannot be subscribed (Lloyd, 1999). The situation ultimately calls for rational management of water resources to ensure its sustainability. Water intended for human consumption must be free from organisms that are the causative agents of diseases and must not contain chemical substances at concentrations that may be hazardous to human health. In addition drinking water should be aesthetically acceptable, free from unpleasant taste, color, odor and turbidity. Drinking water should also be free from bacteria and viruses whose presence would indicate fecal contamination. Some are known to be toxic and their concentrations must be below acceptable value, taking into account that drinking water is but one of the several pathways by which substances enters the body. ix Due to perceived concerns of over extraction and rapid water resources depletion, optimal management of groundwater resources are now receiving much attention. Their associated literatures have taken quite different approaches both philosophically and operationally to the analysis of how groundwater should be managed, allocated and cared for spatially and temporally. This study investigated the spatial and temporal fluctuations of concentrations of chemical and biological substances in groundwater such as pH, electrical conductivity, total dissolved solids, iron, fluoride, manganese, chloride, sulfates, sodium and fecal coliform in Mchinji District of Central Malawi. Through examination and analysis of static water levels as an indicator of water table fluctuations, groundwater availability was also measured. It was found that anthropogenic activities on the landscape can impact the quality and quantity of the water resources in this area and this impact on the various sectors of the inhabitant‟s livelihoods. Groundwater in Mchinji is composed of a number of chemical and biological elements whose origin is either from the material in which it percolates through, or stored before exploitation. Anthropogenic activities in this area plays a role in the quality and quantity of groundwater through land use and land cover change as evidenced by comparisons of Landsat Thematic x Mapper™ satellite images over different time scales. In Mchinji no regular groundwater monitoring is being done indicating a deficiency in sustainability interventions of the resource. This study calls for integrated and sustainable water resources management and coordinated efforts amongst water users, local councils, regulatory authorities and environmental policy makers. Of far greater importance in groundwater sustainability analysis is the issue of groundwater monitoring. It is imperative therefore to preserve the resource while preservation is still possible. Groundwater is now turning into „blue gold‟ and becoming a highly sought-after commodity. It should, however, be utilized sustainably to meet the needs of the present without compromising the ability of future generations to meet their own needs.

- Description: The aim of the study was to analyse the framework for measuring parliamentary performance in South Africa. The researcher wanted to assess the current system challenges and gaps for measuring performance of the Parliament of the Republic of South Africa with special reference to the core business of Parliament and to provide a performance management model and tools that can be adopted by Parliament to address the core business of Parliament challenges and problems. In this study, relevant literature was reviewed. The researcher dwelled on the concept of performance management, historical perspective, elements of performance management and benefits derived from the system. The critical issue that was discussed under this section was the comparison amongst countries. It was evident that there are countries that are measuring both administrative and political arm of government. The data collection instruments that were used were questionnaires and interviews. Questionnaires were distributed to The Secretariat to the National Parliament, Chief Directors, General Managers and Senior Managers. Interviews were held with Presiding Officers: Speaker, Deputy Speaker, Chairperson of Chairpersons, and Deputy Chairperson of Chairpersons, Chief Whips, Whips of Committees and Chairpersons of Committees. A thematic analysis was employed and the Statistical Package for the Social Sciences (SPSS) was used. After analysing the data, the researcher arrived at conclusions and thereafter suggested recommendations. The researcher proffered a model by examining different best models of the world and selecting some of those components. The model indicates performance outcomes, which are; accountability, responsiveness, representativity, transparency and impact as well as parliamentary mandates, which are the Constitutional mandates in a matrix.
