- Description: Zimbabwe is one of the priority countries nominated by the World Health Organisation and the Joint United Nations Programme on HIV and AIDS to adopt and implement voluntary medical male circumcision (VMMC) because of its high rate of HIV prevalence and its low level of male circumcision. VMMC, which was introduced in Zimbabwe in 2009, is a new HIV prevention method which reportedly offers partial protection of about 60 percent for circumcised males with respect to contracting HIV through sexual relations. The other key prevention method, namely the use of condoms consistently and correctly, has a protection rate of up to 95 percent. As a result, because of only partial protection, medically-circumcised men are encouraged to use condoms to decrease the chances of HIV infection. Concerns though have been raised about the possibility of risk compensation by circumcised males by way of increases in unsafe or risky sexual practices subsequent to circumcision and arising from perceptions of reduced risk through VMMC. This compensation may take the form of condom use aversion including when involved with concurrent sexual partners. If risk compensation does take place, this would lead to increases in HIV transmissions affecting not only the circumcised men but their sexual partners as well. The supposed effectiveness of VMMC as a HIV prevention method has been subjected to significant criticism and, as yet, no significant study has been undertaken in Zimbabwe on the relationship between VMMC, condom use, concurrent sexual partners and risk compensation. Based on a study of twenty-five medically-circumcised males in Harare, the capital of Zimbabwe, this thesis seeks to understand and explain the relationship between voluntary medical male circumcision and risky sexual practices with particular reference to condom use amongst men engaged in concurrent sexual partnerships. While the thesis finds evidence of risky sexual practices subsequent to circumcision, risk compensation does not seem to be particularly prevalent.

- Description: The effect of real exchange rate volatility on export performance: evidence from South Africa (2000-2011) This study sought to investigate the relationship between exchange rate volatility and export performance in South Africa. The main objective of the study was to examine the impact of exchange rate volatility on export performance in South Africa. This relationship was examined using GARCH methods. Exports were regressed against real effective exchange rate, trade openness and capacity utilisation. The research aimed to establish whether exchange rate volatility impacts negatively on export performance in the manner suggested by the econometric model. The result obtained showed that exchange rate volatility had a significantly negative effect on South African exports in the period 2000-2011.

- Description: Discourse characterising climate change has largely revolved around aspects within the realm of impact identification, mitigation and adaptation. Apparently, a burgeoning appetite to examine the role of indigenous knowledge (IK) now confronts the fronts of climate science, policy and practice. The surge in attention to localbased knowledge is attributed to growing challenges posed by change and variability in the climate system. This study argues that indigenous-based knowledge is capable of filling knowledge gaps and validating current understanding about climate change particularly at local levels. Essentially, the paucity of knowledge about local climatic events can be circumvented by engaging indigenous ‘scientists’ whose many years of direct contact with the environment have equipped them with the indispensable knowledge, skills and experiences to understand the same. Primarily, the thesis’ objectives were threefold. One, it captured useful indicators of climate change and variability from the understanding of the indigenous people, which can also be used to enhance understanding of climate change impacts.Two, it drew from the knowledge, experiences, skills and practices of the locals in order to inform appropriate community level mitigation and adaptation interventions. And, three, it highlighted the fact that knowledge of the indigenous people can be used to direct research on climate change. The study area (Muzarabani in Zimbabwe) experiences recurrent droughts and floods and its villagers rely predominantly on climate-sensitive livelihoods. As such, it was selected to provide a reliable case on IK practices and experiences of the people witnessing climatic events. The study was framed within an epistemological and methodological configuration of emancipatory pedagogy that looks at the generators of climate knowledge as ‘scientists’ in their own right. A qualitative elicitation interviewing technique involving in-depth discussions with traditional leaders and elderly knowledgeable citizens was conducted. The participants were selected through chain referrals until the level of theoretical saturation. In addition, directed field observations, document analysis and key informant interviews with other respondents selected through theoretical sampling enhanced the robustness of data acquisition methods. Group-based participatory data analysis and reflexive pragmatism also enhanced rigour and quality of research findings intended to balance between the strictures of the scientific audience and the views of the knowledge generators. Three key themes were derived from IK-climate change linkages as: indigenous based indicators of climate change, indigenous-based mitigation and indigenous based adaptation. A range of indigenous-based indicators identified pointed to a progressively drier climate with shorter growing seasons that are also punctuated by mid-season dry spells. A trend towards increased desiccation of water bodies (rivers, ponds and vleis) was further observed. There is also an upsurge in the abundance and pestiferous nature of Macrotermes spp, Quelea quelea and Acanthoplus discoidalis, which are most likely related to climate change. Some of these indicators closely match with those used in mainstream climate science and they also serve to understand climate change impacts at a finer local level of analysis. Indigenous-based mitigation is mainly driven by the notion of sacredness where the locals regard forestry, certain trees and vleis as sacrosanct. Tampering with these is believed to upset the spirits who have powers to influence climate. Opportunities associated with IK deployment in climate mitigation are understood from the viewpoint of enhancing greenhouse gas (GHG) sinks and that of reducing vulnerability to extreme climatic events. Specifically, this can be achieved through enhancing GHG sequestration through forestry and land-use management initiatives; that is, reducing emissions from deforestation and forestry related degradation (REDD+) and Land Use and Land-Use Cover and Forestry (LULUCF). These two are the dominant schemes adopted by the Intergovernmental Panel on Climate Change (IPCC) to govern climate mitigation. Indigenous disaster risk management (DRM) strategies abound in drought, famine, flood and violent storms through various forms such as Zunde raMambo, nhimbe, rain-making ceremonies and community early warning systems (EWS).The locals in Muzarabani are not passive observers of the changing climate system. Increasing environmental risks necessitates them to devise countermeasures for responding to climatic stimuli with the intention of minimising harm and/or enhancing the benefits brought about by the same. Thus, a portfolio of IK-based adaptation strategies best described as an assortment of short-term coping practices and longterm adaptive strategies were identified. These range from exploitation of ecosystem services, agricultural based interventions, riverine farming, traditional phonological knowledge (TPK) to migration. Therefore, it was revealed that community-based adaptation (CBA) can adequately leverage on IK to improve adaptive capacity and build community resilience against climate change. Clearly, the complementary role of indigenous-based knowledge cannot be disputed, given the demonstrated range of applications from identifying several indicators of change and variability in the climate system, examination of climate change impacts, to identification and assessment of mitigation and adaptation options. The study advises that exogenous climate interventions need to be congruent with indigenous based strategies to avoid maladaptation. To the climate research community therefore, it should be realised that IK is useful both as leads and as baseline knowledge for future work on the impacts of climate change, and in the assessment of climate interventions. In this regard, the remaining challenge is to formulate a framework of constructive dialogue between indigenous scientists and conventional scientists so as to make sure that the mutual benefits of the two knowledge forms are adequately harnessed. Handled well, such collaborative effort would ensure enhanced climate change knowledge for successful mitigation and adaptation strategies. Handled poorly, there is a risk that the developmental needs of communities exposed to climatic events would not be addressed.

- Description: Since the launch of the Biofuels Industrial Strategy in 2007 by the South African government, only a few smallholder farmers have adopted biofuels for production. The government hopes to stimulate economic development and alleviate poverty by targeting areas that were previously neglected for agriculture by the apartheid government. However, there still appears to be a lack of a clear and comprehensive policy framework for the development of a South African biofuel industry, because the proposed initiatives have not been implemented to date. There are also concerns among stakeholders that government policy is taking too long to formulate, compounding existing uncertainty in the industry. This study therefore aims to identify barriers and incentives that influence the potential adoption of biofuel crops in selected areas in the Eastern Cape Province, South Africa. The study utilised a semi-structured questionnaire to record responses from 129 smallholder farmers that were identified through a snowballing sampling technique. Descriptive statistical analysis and a Heckman two-step model were applied to analyse the data. Analysis was done using SPSS 21 and EViews 8. Results obtained showed that the variables: arable land, incentives offered, challenges faced, labour source and farm experience were statistical significant at 5 or 10 percent p value to awareness of farmers to biofuel crops. Adoption of biofuel crops was statistically related to gender, qualification, membership to association and household size. The study recommends that the Biofuels Industrial Strategy Policy be revisited in order to have a mechanism of including smallholder farmers that it aims to empower with employment and improvement in their livelihoods. The government can help smallholder farmers by addressing the challenges they face in improving their output. Furthermore, it recommends that a national study on barriers and incentives that influence the adoption of biofuel crops be carried out in order to identify other factors that may hinder the Biofuels Strategy Policy aims in empowering the disadvantaged farmers.

- Description: Career psychology in South Africa has traditionally been constituted by assessment methods, counselling practices and research objectives of a modernist-positivist paradigm. This paradigm has been limited in its consideration and integration of the broad range of contextual factors that may influence the career development of individuals. This study is based on the Systems Theory Framework of career development, an overarching theoretical framework of career development that is able to acknowledge the complexity of career development processes and assist in engaging with contexts of that complexity. Seven Xhosa-speaking Black South African female university students were invited to story their career development within their unique individual contexts. In collaborating with the participants, the study adopted an exploratory collective case study research design. The My Systems of Career Influences reflection process was primarily used to obtain the qualitative data. Based on the need that arose in the career counselling process, the quantitative data were generated from the Values Scale (VS), the Life Roles Inventory (LRI), the Commitment to Career Choices Scale (CCCS), and the Jung Personality Questionnaire (JPQ). The study is particularly relevant given the growing need for the development of non-discriminatory career assessment and counselling collaborations between counsellors and clients who need to navigate unique and diverse South African contexts. Key words: career counselling, career development, constructivism, My System of Career Influences (MSCI), narrative career counselling, qualitative career assessment, South African female university students, storytelling approach, Systems Theory Framework (STF).

- Description: In 2006, a new subject, Religion Studies (RS), was introduced in Grade 10 as an optional subject. It represents a major paradigm shift in education of religion at the public school level. Minimal research has been conducted on the factors influencing the choice of RS in Grade 10 by the learners, subject advisors, principal and educators. This subject might constitute an “easy option” to boost the learner’s performance. Former or “recycled Biblical Studies” educators may be available or even volunteer to teach this subject or they may have to be absorbed within the system. Ethics, morals, cross cultural respect and non-discrimination are critical for the development of the South African democracy. While RS is optional, it could play a critical role towards achieving these outcomes. This study restricted its focus to the Uitenhage District of the Province of the Eastern Cape. After careful consideration, the interpretive approach seemed to offer the best access to the kind of knowledge the researcher desired. A theoretical framework, that narrowly links rational choice with cultural reproduction theory, can prove to be inadequate. This study would be deficient if it was restricted to the family or home factors. Peer influence, self-efficacy or ability, utility value, motivation and teacher or school factors have to be included. The case study approach was used for this research.Semi-structured interviews were used to obtain qualitative responses from learners, from principals and educators whose schools are offering Religion Studies, and from subject advisors with oversight of this subject. This study discovered, inter alia, that learners did not have a real choice but were led to believe that RS was compulsory. The school has an influential role on a learner’s subject choice. Parental participation fluctuated from active to passive guidance. Learners saw RS as an easy subject and an aggregate booster. The school community both informs and influences the subject choice of learners. The peer influence of friends and fellow learners also featured in subject choice. RS teaches about religion and culture, respect, catalyses moral development, is enjoyable and easy to study but requires extensive reading. The limited diversity in RS classes did not allow for this respect to be tested. RS can catalyse the development of moral values. Despite this subject being an aggregate booster, learners enjoyed RS and therefore do well. After balancing the “costs and benefits,” according to rational choice theory, learners choose subjects with a utility value for their future career. RS opens the possibilities directly and indirectly. The majority of learners said that RS will assist them in their career path, not only narrowly in religious and pedagogical vocations but also more widely. RS could assist in careers with constituencies of religious diversity, in the medical field, human resources and journalism. RS fosters citizenship, non-discrimination and the rounded development of the learner and these objectives have attracted educators to teach RS. Learners enjoy RS, have self-efficacy, their performance ranges from good to well. Educators have a positive view of RS and contend that RS fosters respect, analytical, critical, constructive and lateral thinking. Principals were introduced to RS when it replaced Biblical Studies and much confusion between the two has ensued. RS is inclusive and also catalyses the development of morals. Principals emphasised the ongoing need for retraining of teachers through refresher courses, workshops and seminars and an involved role of the Department. Retraining would prevent the RS educator from being an “ad hoc teacher.” The Department has failed to act proactively in the introduction of RS as a new subject. Challenges lie in the integration of learning, essay writing skills and developing good model assessment tasks. Understanding RS terminology, confusion of RS with Biblical Studies, a shortage of resources, the vast content and the subject related methodology of RS are other concerns. All the stakeholder groups confirm this misperception. Researchers also concur with this finding. Biblical Studies educators have no advantage in RS but rather also necessitate retraining. RS, as a new subject with low intake, was not afforded all the requisite support. The number of schools offering RS is static. Provincial officials also reflect confusion of RS and Biblical Studies. The lack of staffing of the subject specialist at the National or Provincial level office is perturbing. Based on this study of the factors influencing the choice of Religious Studies in the FET Band, the following recommendations were made: Steps should be taken to ensure that learners be given a real choice Sharing of detailed information about the unique nature and outcomes of RS including its critical engagement Informed stakeholder groupings e.g. parents, educators, principal, SGB, community, Provincial and National Department of Education should not abuse their influential role of support by overt or covert compulsion Clarity between spiritual formation and catalysing moral development Educators should continue to foster enjoyment of RS Steps to be taken to facilitate integration of learning, developing essay writing skills and encourage good assessment tasks Increase diversity in class so that respect can be tested More information be given about direct and indirect career pathing Need for continual re-training through refresher courses, workshops and seminars Steps to be taken to address inadequate resources of RS Despite the “flattering” results for RS, efforts need to be taken by all the stakeholder groupings to ensure that learner’s competencies become a means in which RS markets itself Concerted on-going effort be made to clarify the confusion between RS and Biblical Studies That the Department assumes a more engaged role in RS Steps be taken by all the stakeholder groupings to encourage religious diversity in the RS class The National Department of Education has to staff both the National and Provincial Offices with well-equipped and highly motivated leaders.

This study discovered, inter alia, that learners did not have a real choice but were led to believe that RS was compulsory. The school has an influential role on a learner’s subject choice. Parental participation fluctuated from active to passive guidance. Learners saw RS as an easy subject and an aggregate booster. The school community both informs and influences the subject choice of learners. The peer influence of friends and fellow learners also featured in subject choice. RS teaches about religion and culture, respect, catalyses moral development, is enjoyable and easy to study but requires extensive reading. The limited diversity in RS classes did not allow for this respect to be tested. RS can catalyse the development of moral values. Despite this subject being an aggregate booster, learners enjoyed RS and therefore do well. After balancing the “costs and benefits,” according to rational choice theory, learners choose subjects with a utility value for their future career. RS opens the possibilities directly and indirectly. The majority of learners said that RS will assist them in their career path, not only narrowly in religious and pedagogical vocations but also more widely. RS could assist in careers with constituencies of religious diversity, in the medical field, human resources and journalism. RS fosters citizenship, non-discrimination and the rounded development of the learner and these objectives have attracted educators to teach RS. Learners enjoy RS, have self-efficacy, their performance ranges from good to well. Educators have a positive view of RS and contend that RS fosters respect, analytical, critical, constructive and lateral thinking. Principals were introduced to RS when it replaced Biblical Studies and much confusion between the two has ensued. RS is inclusive and also catalyses the development of morals. Principals emphasised the ongoing need for retraining of teachers through refresher courses, workshops and seminars and an involved role of the Department. Retraining would prevent the RS educator from being an “ad hoc teacher.” The Department has failed to act proactively in the introduction of RS as a new subject. Challenges lie in the integration of learning, essay writing skills and developing good model assessment tasks. Understanding RS terminology, confusion of RS with Biblical Studies, a shortage of resources, the vast content and the subject related methodology of RS are other concerns. All the stakeholder groups confirm this misperception. Researchers also concur with this finding. Biblical Studies educators have no advantage in RS but rather also necessitate retraining. RS, as a new subject with low intake, was not afforded all the requisite support. The number of schools offering RS is static. Provincial officials also reflect confusion of RS and Biblical Studies. The lack of staffing of the subject specialist at the National or Provincial level office is perturbing. Based on this study of the factors influencing the choice of Religious Studies in the FET Band, the following recommendations were made: Steps should be taken to ensure that learners be given a real choice Sharing of detailed information about the unique nature and outcomes of RS including its critical engagement Informed stakeholder groupings e.g. parents, educators, principal, SGB, community, Provincial and National Department of Education should not abuse their influential role of support by overt or covert compulsion Clarity between spiritual formation and catalysing moral development Educators should continue to foster enjoyment of RS Steps to be taken to facilitate integration of learning, developing essay writing skills and encourage good assessment tasks Increase diversity in class so that respect can be tested More information be given about direct and indirect career pathing Need for continual re-training through refresher courses, workshops and seminars Steps to be taken to address inadequate resources of RS Despite the “flattering” results for RS, efforts need to be taken by all the stakeholder groupings to ensure that learner’s competencies become a means in which RS markets itself Concerted on-going effort be made to clarify the confusion between RS and Biblical Studies That the Department assumes a more engaged role in RS Steps be taken by all the stakeholder groupings to encourage religious diversity in the RS class The National Department of Education has to staff both the National and Provincial Offices with well-equipped and highly motivated leaders.

- Description: Ants are fascinating creatures - not so much because they are intelligent on their own, but because as a group they display compelling emergent behaviour (the extent to which one observes features in a swarm which cannot be traced back to the actions of swarm members). What does each swarm member do which allows deliberate engineering of emergent behaviour? We investigate the development of a language for programming swarms of ant agents towards desired emergent behaviour. Five aspects of stigmergic (pheromone sensitive computational devices in which a non-symbolic form of communication that is indirectly mediated via the environment arises) and message passing ant agents (computational devices which rely on implicit communication spaces in which direction vectors are shared one-on-one) are studied. First, we investigate the primitive behaviours which characterize ant agents' discrete actions at individual levels. Ten such primitive behaviours are identified as candidate building blocks of the ant agent language sought. We then study mechanisms in which primitive behaviours are put together into XSets (collection of primitive behaviours, parameter values, and meta information which spells out how and when primitive behaviours are used). Various permutations of XSets are possible which define the search space for best performer XSets for particular tasks. Genetic programming principles are proposed as a search strategy for best performer XSets that would allow particular emergent behaviour to occur. XSets in the search space are evolved over various genetic generations and tested for abilities to allow path finding (as proof of concept). XSets are ranked according to the indices of merit (fitness measures which indicate how well XSets allow particular emergent behaviour to occur) they achieve. Best performer XSets for the path finding task are identifed and reported. We validate the results yield when best performer XSets are used with regard to normality, correlation, similarities in variation, and similarities between mean performances over time. Commonly, the simulation results yield pass most statistical tests. The last aspect we study is the application of best performer XSets to different problem tasks. Five experiments are administered in this regard. The first experiment assesses XSets' abilities to allow multiple targets location (ant agents' abilities to locate continuous regions of targets), and found out that best performer XSets are problem independent. However both categories of XSets are sensitive to changes in agent density. We test the influences of individual primitive behaviours and the effects of the sequences of primitive behaviours to the indices of merit of XSets and found out that most primitive behaviours are indispensable, especially when specific sequences are prescribed. The effects of pheromone dissipation to the indices of merit of stigmergic XSets are also scrutinized. Precisely, dissipation is not causal. Rather, it enhances convergence. Overall, this work successfully identify the discrete primitive behaviours of stigmergic and message passing ant-like devices. It successfully put these primitive behaviours together into XSets which characterize a language for programming ant-like devices towards desired emergent behaviour. This XSets approach is a new ant language representation with which a wider domain of emergent tasks can be resolved.

- Description: Despite according high priority to regional economic integration and being clustered by regional economic schemes, Africa’s regional economic integration record is not inspiring. With the transformation of the OAU to the African Union (AU), the New Partnership for Africa`s Development (NEPAD) was adopted as the development program of the continent to drive the impetus of economic integration through trade. At the time NEPAD was adopted, regional integration schemes in Africa were facing problems of low intra-regional trade levels despite trade being identified as the engine of activity and economic growth for regional economic integration. The study was centered on Southern Africa with precise attention on SADC. Even though trade is accepted as a vital engine of economic growth and development, this is not the case with SADC. The study was looking at the contribution of NEPAD in intra-regional trade in Africa with special focus on SADC. This was prompted by the fact that regional integration is business as usual within the sub region while problems that have been confronting regional schemes are continuing unabated after the adoption of NEPAD. The study used the historical approach because it provides the study with an advantage of accessing existing literature with regards to what is really stalling intra-regional trade in SADC. The study findings noted that NEPAD has not fully addressed the problems of intra-regional trade within SADC and the continent at large. The study lastly concludes by giving a way forward for NEPAD to respond to the specific needs of SADC for the promotion of intra-regional and equitable trade.

- Description: South Africa, many plants which are used in traditional medicines are collected from wild populations. The high demand for trade and use of these medicinal plants place an enormous pressure on their natural populations, especially because they are indiscriminately harvested. The most affected of these plant species are those harvested from their underground parts, among which is Gunnera perpensa L. Gunnera perpensa is of considerable ethnobotanical interest in traditional medicine because of its wide usage. The rhizomes are widely used and indiscriminately collected in large quantities from the wild to meet the ever increasing demand in traditional medicine markets. As a result, this valuable medicinal plant species is being endangered. According to the Red List of South African Plants, the conservation status of G. perpensa has been listed as ‘declining’. The ethnobotanical survey conducted as part of this research confirms the plant species as threatened. It is, therefore, important to develop propagation and conservation strategies for this medicinal plant. Clonal propagation of G. perpensa was conducted using varying lengths of the rhizome (1, 2, 3, 4 and 5 cm) segments as propagules. While regeneration was possible with all the rhizome lengths, most of the growth parameters were significantly higher in the 5 cm rhizomes than the other rhizome segments. The appropriate planting depth for the rhizomes was also determined and 4 or 5 cm planting depths were found appropriate. No significant difference was observed in the growth parameters amongst the planting depths; nevertheless, 4 cm depth gave higher growth and yield. The results of this study show that regenerating G. perpensa.

- Description: With the rapid adoption of multimedia network technologies, a number of companies and standards bodies are introducing technologies that enhance user experience in networked multimedia environments. These technologies focus on device discovery, connection management, control, and monitoring. This study focused on control and monitoring. Multimedia networks make it possible for devices that are part of the same network to reside in different physical locations. These devices contain parameters that are used to control particular features, such as speaker volume, bass, amplifier gain, and video resolution. It is often necessary for changes in one parameter to affect other parameters, such as a synchronised change between volume and bass parameters, or collective control of multiple parameters. Thus, relationships are required between the parameters. In addition, some devices contain parameters, such as voltage, temperature, and audio level, that require constant monitoring to enable corrective action when thresholds are exceeded. Therefore, a mechanism for monitoring networked devices is required. This thesis proposes relationships that are essential for the proper functioning of a multimedia network and that should, therefore, be incorporated in standard form into a protocol, such that all devices can depend on them. Implementation mechanisms for these relationships were created. Parameter grouping and monitoring capabilities within mixing console implementations and existing control protocols were reviewed. A number of requirements for parameter grouping and monitoring were derived from this review. These requirements include a formal classification of relationship types, the ability to create relationships between parameters with different underlying value units, the ability to create relationships between parameters residing on different devices on a network, and the use of an event-driven mechanism for parameter monitoring. These requirements were the criteria used to govern the implementation mechanisms that were created as part of this study. Parameter grouping and monitoring mechanisms were implemented for the XFN protocol. The mechanisms implemented fulfil the requirements derived from the review of capabilities of mixing consoles and existing control protocols. The formal classification of relationship types was implemented within XFN parameters using lists that keep track of the relationships between each XFN parameter and other XFN parameters that reside on the same device or on other devices on the network. A common value unit, known as the global unit, was defined for use as the value format within value update messages between XFN parameters that have relationships. Mapping tables were used to translate the global unit values to application-specific (universal) units, such as decibels (dB). A mechanism for bulk parameter retrieval within the XFN protocol was augmented to produce an event-driven mechanism for parameter monitoring. These implementation mechanisms were applied to an XFN-protocol-compliant graphical control application to demonstrate their usage within an end user context. At the time of this study, the XFN protocol was undergoing standardisation within the Audio Engineering Society. The AES-64 standard has now been approved. Most of the implementation mechanisms resulting from this study have been incorporated into this standard.

- Description: This study investigates the Zimbabwean women listeners of a gender-focused radio programme Nguva yevanhukadzi (Time for Women) to find out what meanings they take from the programme. Located within the broad theoretical framework of cultural studies and drawing on audience reception theories, the study focuses on the ways in which Shona-speaking women bring their understandings of their social roles, derived from their lived socio-cultural experiences of patriarchy, to their decoding of the text. The study was set in Harare’s high-density suburb of Mbare and used the qualitative research methods of individual and focus group interviews. The study was conducted against the backdrop of the signing of the Global Political Agreement (GPA) of September 2008, which ended the impasse among the warring political parties, ZANU PF, MDC-T and MDC and introduced a new era of collectively tackling socio-economic development, including redressing gender disparities through women’s empowerment. This study examines the factors shaping the audiences’ readings of the programme and seeks to establish whether the mass media has determining power on its audience in the reception of messages or if the audiences (women) have interpretive freedom. Using Hall’s (1980) Encoding/ Decoding model, the study examines the factors that influence the audiences’ choice in making preferred, negotiated or oppositional readings and the arguments they advance in line with those readings. While the interviews revealed that most of the female listeners “negotiated” the dominant encoded meanings, seeking their relevance to their varied situations and contexts (O’ Sullivan et al. 1994:152; Ang 1990: 159), of interest is the manner in which the women dealt with the discourse of patriarchy within the context of promoting women empowerment. The contestation between women empowerment and addressing patriarchy reflected the subverted notions of maintaining the status quo, while applauding the women’s commitment and ability to interrogate the practicality of issues under discussion and drawing lessons relevant to their day to day lives prior to making the preferred reading. As such, the study revealed that preferred readings are not always automated, but can be a result of intense interrogation among media audiences.

- Description: Social protection measures are poverty reduction interventions implemented to assist in reducing poverty shocks of communities. This study considered the Farm Input Subsidy Programme (FISP) that has been implemented in Malawi with the aim of reducing poverty amongst subsistence farmers by providing them with subsidized farm inputs. The study was conducted in the rural area of Lilongwe District, under Traditional Authority Kabudula. The study mainly focussed on the outcomes of implementing the FISP and it entails whether or not the poverty reduction intervention is really achieving its goals. Thus, the study greatly evaluates the effectiveness of subsidizing farm inputs in reducing poverty amongst households in rural communities characterised by subsistence farming. This study was mainly qualitative in nature and data was collected through interviews and Focus Group Discussions. Some quantitative data for specific trends of national indicators was collected through document. Mainly, content analysis was used to analyse the qualitative data and descriptive statistical analysis with the aid of Microsoft Excel was engaged to analyse the quantitative data. The study found that that FISP assist in household food security only in the short term. Among the reasons cited, the package size received by households has become smaller with sharing tendencies that have been devised to help households that do not receive the inputs or qualify to receive them. This practice is compromising the agricultural productivity in terms of quantities as it lasts only in the short-term before the next harvest. When households’ food reserves are depleted, households become food insecure and poverty sets in again. The study thus reveals that FISP implementation is not operating as a sustainable programme as its intended goal is not being achieved in the long-term. The study also found that coupled with the fact that there is no clear policy guidelines on graduation and that there is continued benefitting of the same beneficiaries, FISP is nowhere close to its phasing-out stage in social protection perspective.

This practice is compromising the agricultural productivity in terms of quantities as it lasts only in the short-term before the next harvest. When households’ food reserves are depleted, households become food insecure and poverty sets in again. The study thus reveals that FISP implementation is not operating as a sustainable programme as its intended goal is not being achieved in the long-term. The study also found that coupled with the fact that there is no clear policy guidelines on graduation and that there is continued benefitting of the same beneficiaries, FISP is nowhere close to its phasing-out stage in social protection perspective.

- Description: With the world's population expected to reach nine billion by 2050, agricultural production will have to double to meet this growing demand. Hence, a need for better infrastructure to enhance farming efficiency becomes apparent. There are a number of solutions that have been developed to date that are commercially available. They range from genetically modified seeds and bio/green fertilizers to advanced farming machinery amongst others. However most of the farming equipment developed has drawbacks such as: heavy weight – this leads to reduced yields due to soil compacting; human dependency – constant monitoring and controlling is needed; light dependency – excludes usage during the night or when visibility is poor. Therefore, a possible solution will be researched to enhance the evolution of farming equipment. Furthermore, a model will be developed for testing and verifying the research.

- Description: This study examined the information – seeking behaviour of members of the economically disadvantaged community of Amsterdam. The study involved both a qualitative and quantitative investigation of the critical factors that affected information – seeking, need, and use in the Amsterdam community. The research design included a study of various information behaviour models with particular emphasis on Wilson’s 1996 general model of information – seeking behaviour. The three factors identified by Wilson for the study of various groups’ information behaviour were personality, work – related or work – role and environmental factors. Information science researchers, in the study of rural communities’ information behaviour, have used these three factors extensively. The data collection was triangulated with the use of survey, observations, and focus group discussions and in – depth interviews. The findings show how the person, in the context of information – seeking and the role-played within a given environment, could determine information needs and use. A person in the context of information – seeking, could be a father, a mother, a group leader, a nurse or a teacher. The main elements are the situation within which a need for information arises, and the person performing a role in an environment situated within the context of information – seeking. Information was found to be a critical commodity for the socio – economic, political, and educational development of any given community. Recommendations were made that could transform the community of Amsterdam, through the provision of sustainable information.

- Description: The Kansanshi Cu-Au deposit located in the Domes region of the North West province of Zambia is characterised by structurally controlled high angle veins and associated alteration halos. The northwest trending Kansanshi antiform flanks the Solwezi syncline to the north and hosts the Kansanshi deposit and consists of tillites and metasedimentary rocks. Mineralisation is associated with Neoproterozoic Pan African deformation events experienced during the formation of the Lufilian fold belt; however recent findings confirm that structures in the form of reverse and normal faults and drag folds are critical controls on mineralisation within the deposit, Main pit in particular. Low angle faults occurring below the current pit are believed to have served as major fluid pathways during mineralisation. Age dating data from the Kansanshi deposit suggest that mineralisation took place between 512 and 503 Ma indicating that the event was associated with metamorphism. Two types of alteration are dominant within the Main pit (Kansanshi deposit) with the type and intensity of alteration being largely controlled by lithological units. Albite alteration occurs dominantly in phyllites and schists whereas dolomitisation is prevalent in calcareous units. Alteration is associated with mineralisation, and therefore is used as a condition for predicting vein or disseminated mineralisation. The high Au tenor at Kansanshi can be attributed to gold grains occurring in association with melonite (NiTe₂) and microfractured pyrite intergrown with chalcopyrite in sulphide and quartz dominated veins and veinlets. Analysis of gold grade distribution within the Main pit shows a clear concentration of the element along the major north-south trending structures like the 4800 and 5400 zones, possibly through supergene enrichment in the oxide-transition-sulphide zones. It is imperative that exploration for Kansanshi-type deposits will require geochemical and geophysical studies, understanding of the geology of an area to identify the three lithostratigraphic units (red beds, evaporites and reducing strata).

- Description: The teaching profession, like many other professions, has rules and regulations that guide the conduct of its members. Teachers and those who aspire to take up teaching are expected to conduct themselves and discharge their duties in an impeccably professional manner. However, there is concern especially among education authorities regarding unprofessional conduct of some of those employed in schools and colleges. This action research study is a response to this concern. Its goal was to explore issues of professional conduct as part of the induction process of new members entering the teaching profession, and to thereby develop a better understanding of how best to raise student teachers’ awareness around professional conduct issues. The study used a qualitative research framework located in the interpretive paradigm. Three theoretical frameworks informed the design and subsequent analysis of the findings, namely, Burn’s transformational leadership, Mezirow’s transformative learning and Kolb’s theory of experiential learning. Two cycles of workshops around issues of professional conduct were conducted over a period of four weeks with a sample of 40 pre-service student teachers: final year students enrolled in the college’s three year Diploma in Education programme, all members of a science education class. Data collection strategies used were semi-structured interviews, observation and the use of reflective journals, among others. Analysis of the data involved identification of emerging themes and patterns. Initial findings indicate that prior to the commencement of the cycles of action research, participants appeared to have a limited understanding around issues of professional conduct, but that this changed as they participated in the workshops. The data of the study suggest that further steps need to be taken to establish optimal ways of incorporating professional conduct issues into the college’s teaching curriculum.

- Description: Albeit much effort having been put to review the performance trend of smallholder irrigation farmers in South Africa. However, there seems to be a paucity of information regarding the level of entrepreneurship on these farmers. Most research works on smallholder irrigation farmers have mainly focused on livelihoods trajectory providing a review on how the welfare of the rural poor has been transformed after the introduction of irrigation schemes. With most research evidence indicating a high degree of underperformance on most smallholder irrigation schemes, this research attempted to investigate the level of entrepreneurship among the small holder irrigation farmers. In order to achieve the main research objective, a sample of 110 farmers drawn from Qamata irrigation scheme was interviewed and each farmer’s performance on the nine components of entrepreneurship was assessed. The aspects assessed to determine the farmer’s entrepreneurial behaviour were: planning ability, risk taking, achievement motivation, leadership ability, Cosmo politeness, decision making, and innovativeness and farming knowledge. Basing on previous studies which indicated entrepreneurial behaviour to be influenced by several factors the study also analysed the determinants of entrepreneurship among the irrigation farmers and a binary logistic regression model was used to establish the connection between various independent variables and the farmers’ entrepreneurial performance given as a total score of the nine components. Though the findings of the study revealed a prevalently low level of entrepreneurship among the smallholder irrigation farmers on Qamata irrigation scheme, a high proportion of the respondent farmers (65.5% and 60.5%) showed to have a high degree of achievement motivation and decision making ability, respectively. The observed trend thus reflected that smallholder farmers have a potential to become entrepreneurs and are willing to succeed. The binary model results revealed that the prevailing land tenure system will be a strong determinant of the farmer’s level of entrepreneurship. Equally, levels of training in farming, motive for farming and information seeking tendency also proved to have a significant influence on the degree of farmer entrepreneurship. Based on the results of this study recommendations have thus been drawn on the need for policies and practices aimed at promoting entrepreneurship and not dependency among farmers. Key focus areas identified include: the need to revise the current land ii tenure system on irrigation schemes, intensify on entrepreneurship training for both farmers and extension officers and regular on-farm training on new technologies.

- Description: This research study explored the inadequacies of the National Development Plan on addressing the problem of youth unemployment in Eastern Cape in South Africa. The study intended to achieve the following objectives: (i) to evaluate the employment needs of youth in relation to the identified measures of employment creation outlined in the NDP. ii) to identify the gaps in the NDP policy interventions in relation to the prospects and problems embedded in addressing the problem of youth unemployment. The literature reviewed in the study was drawn from several researchers and the study was underpinned by the human capital theory, the capability approach and the public and the private sector partnership theory. Though many theories were used, the human capital theory was the major theory adopted in this study. Since the study was qualitative in nature, an interview guide which consisted of open ended questions was used on face to face interviews and focus groups to collect data from twenty one youth and five youth representatives in the Eastern Cape. The data of this study was thematically analysed. The analysis of the study made the following conclusions about the NDP and youth employment in the Eastern Cape. Firstly, there is a problem of high youth unemployment which is above 50% in the Eastern Cape. Secondly, the NDP’s economic measures have a potential of excluding the youth and as a result, the NDP will inadequately address the employment needs of the youth. Thirdly, the youth appreciated that the NDP is realising the problem of youth unemployment but they are not happy with the NDP’s proposed employment measures of wage subsidies, low wages, labour deregulation and SMMEs because they do not solve the root causes of youth unemployment. Rather, they provide unsustainable and low quality jobs in the long run if not properly monitored. In response to the findings, the study therefore made the following recommendations: The NDP’s economic growth policy to be labour intensive compliant, human capital to match the work place skills requirements, promoting entrepreneurship skills, addressing the root causes rather than focusing on symptoms of unemployment , rethinking on SMMEs, development policies to match the local employment needs, succinct youth employment policy implementation, productivity to match the wages, complementing the private and the public sector in creating youth employment, the NDP to promote adequate link of education to self-employment from the primary level, the NDP to promote higher levels of investment for the employment benefits of the youth and the NDP to fight corruption on the misuse of youth employment grants. The study concluded that NDP’s proposed economic measures will inadequately address the youth employment needs hence there is need for relooking at the NDP to be sustainable employment responsive in nature so as to reduce poverty and inequality.

- Description: A widely held view is that export diversification constitutes an important component of export led growth, and poses a major challenge for many developing countries. Given this, the role of export diversification on economic growth warrants a fresh analysis in South Africa. The primary objective of this study is to determine the impact of export diversification on economic growth in South Africa. In this context, the study seeks to establish the relationship between export diversification, export stability and export growth. Initially, the study examines the extent and structure of export diversification in South Africa; it then empirically establishes the link between export diversification, export stability and export growth. Finally, it develops a model and investigates the effects of export diversification on economic growth in South Africa. As an attempt to fulfill the proposed objectives, this study uses quarterly data for the period 1980 to 2012 as well as data for 28 selected groups of commodities to investigate the effects of export diversification on economic growth in South Africa. Measures of export diversification and structural changes in exports in the context of South Africa were discussed. The findings of this study are that the Commodity Specific Cumulative Experience function showed that plots for manufactured commodities are shifted to the right indicating that the commodities are non-traditional in nature whereas, plots for primary commodities are shifted to the left. Results also indicated that South Africa relies more on traditional exports than manufactured exports. Various measures of export instability were used to calculate the export instability index in South Africa. The results of the study reveal that the South African export basket is slightly diversified, and the less diversified or primary commodities are associated with high instability VECM approach was used to allow us to establish the extent of influence of export diversification and other explanatory variables on economic growth. Consistent with other researchers, the study found that export diversification plays significant roles to economic growth in South Africa. A number of diagnostic checks were employed to validate the parameter evaluation of the outcomes achieved by the model. The model passed all the diagnostic checks. On the whole, the results to a larger extent painted a pictured that export diversification is important or drives economic growth in South Africa. Corroborating our findings with work of other scholars, we conclude that our results are complementary.

- Description: The global working environment has altered dramatically over the last decade and in particular, the workforce has begun to consist of many diverse individuals. The world has become a global marketplace, with boundaries between countries becoming increasingly vague and permeable. Advances in technology and the advent of a global economy have brought people from different countries closer together. Globalisation has precipitated many challenges in modern organisations, and one of these challenges is workforce diversity. Workforces in organisations differ in terms of gender, age, race, ethnicity and sexual orientation. Globally, countries are faced with the spiralling challenge of skills shortages and there is an expanding competition for skilled workers, specifically for those who possess scarce skills. This leads to an expatriation of skills, creating a natural increase in workforce diversity that expands beyond local ethnicity and language. This affects all organisations, including academic institutions such as universities, universities of technology and public further education and training colleges. Given this challenge organisations, educational institutions and other entities are investigating ways to better deal or serve their constituents. Lovedale PFET College is a public further education and training college that provides skills to young South Africans, specifically vocational related skills. The main research problem of this study was to identify the recommended diversity management best practices that characterise effective organisations and determine the extent to which these practices are applied at Lovedale PFET College. In order to address the problem, a theoretical study was conducted which focused on identifying the recommended diversity management best practices. In addition, interviews were conducted with managers at Lovedale College to gain an understanding of their perspective on diversity management. Based on the combined main points gleaned from theory and the interviews, a questionnaire was developed and administered to both academic and support staff at Lovedale PFET College to obtain their perceptions of the diversity practices and outcomes at the college. The results of the survey revealed that Lovedale PFET College could improve on the implementation of best practices in diversity management. Specifically, attention could be given to diversity education and training, and diversity management policies and procedures.

- Description: The global working environment has altered dramatically over the last decade and in particular, the workforce has begun to consist of many diverse individuals. The world has become a global marketplace, with boundaries between countries becoming increasingly vague and permeable. Advances in technology and the advent of a global economy have brought people from different countries closer together. Globalisation has precipitated many challenges in modern organisations, and one of these challenges is workforce diversity. Workforces in organisations differ in terms of gender, age, race, ethnicity and sexual orientation. Globally, countries are faced with the spiralling challenge of skills shortages and there is an expanding competition for skilled workers, specifically for those who possess scarce skills. This leads to an expatriation of skills, creating a natural increase in workforce diversity that expands beyond local ethnicity and language. This affects all organisations, including academic institutions such as universities, universities of technology and public further education and training colleges. Given this challenge organisations, educational institutions and other entities are investigating ways to better deal or serve their constituents. Lovedale PFET College is a public further education and training college that provides skills to young South Africans, specifically vocational related skills. The main research problem of this study was to identify the recommended diversity management best practices that characterise effective organisations and determine the extent to which these practices are applied at Lovedale PFET College. In order to address the problem, a theoretical study was conducted which focused on identifying the recommended diversity management best practices. In addition, interviews were conducted with managers at Lovedale College to gain an understanding of their perspective on diversity management. Based on the combined main points gleaned from theory and the interviews, a questionnaire was developed and administered to both academic and support staff at Lovedale PFET College to obtain their perceptions of the diversity practices and outcomes at the college. The results of the survey revealed that Lovedale PFET College could improve on the implementation of best practices in diversity management. Specifically, attention could be given to diversity education and training, and diversity management policies and procedures.
