- Description: It has been reported that the morphology, crystalline phase composition and electrochemical properties of counter electrode materials such MxS (Mo, V) and carbon supported MxS (Mo, V) composite nanomaterials was of considerable importance because it governs the efficiency of many photon assisted chemical and physical reactions in dye sensitized solar cells (DSSCs). The efficiency of DSSCs with composite counter electrode materials is reliant on the stability of the photochemistry reactions which can be optimized by appropriate doping levels of the composite materials. Moreover, the microstructure such as surface area, distribution of the MxS (Mo, V) and carbon supported MxS (Mo, V) composite nanomaterials, and the stability of the electrostatic bonds between the MxS (Mo, V) with the carbon support also play a significant role in the performance of the DSSCs. This work evaluates the effect of different mole ratios of the MxS (Mo, V) and carbon supported MxS (Mo, V) composite nanomaterials on the morphological, structural and electrochemical properties of the composite materials. MoS2 nanoflakes nanostructures have been synthesized by hydrothermal technique using sodium orthovanadate (Na2MoO4) as precursor. In this work Carbon supported MoS2 NFs have been prepared by physically/chemically mixing different mole ratios of MoS2 NFs with multi-walled carbon nanotubes (MWCNTs) and polyvinylidene in N-methyl-2-pyrrolidinone. The morphological, structural and electrochemical properties of the composite counter electrode materials have been investigated using SEM, XRD FTIR, TEM, RS and CV. SEM analysis has revealed the presence of large MoS2 nanoflakes (NFs) as synthesized. SEM analysis has also revealed significant change in the surface morphology of carbon supported MoS2 composite nanostructures with the change in the mole ratio of the MoS2 NFs and carbon support multi-walled carbon nanotubes. Structural analysis through HRTEM analysis revealed a d-spacing of 0.65 nm with a corresponding (002) lattice plane belonging to a trigonal crystalline phase of MoS2. Also, HRTEM analysis has revealed d-spacing of 0.291 nm corresponding to 002 plane of MWCNTs. Raman spectroscopy has revealed Characteristic Raman vibration frequencies and symmetries at 264.6 cm-1(Eg), 354.2 cm-1 (Ag ) belonging trigonal phase of MoS2 (1T-MoS2). FTIR analysis has revealed a narrow peak at 457.6 cm-1 due Mo-S vibration bond. This observation confirms the success of synthesis of MoS2 nanostructures. Cyclic voltammetry (CV), charge-discharge (CD) and electrochemical impedance spectroscopy (EIS) measurements have revealed that the ratio 6:3:1 have shown to be optimum ratio due to its large reduction rate compared to pristine MoS2 NFs and other carbon supported MoS2 NFs. Calculated Rreduction for the carbon supported MoS2 NFs is the order 3:6:1>1:8:1>6:3:1>8:1:1 indicating the trend of ratio 3:6:1 appeared to have higher reduction rate than the rest of the material and it had far less ΔEpp than the rest of other ratios. All CV curves for both pristine MoS2 NFs and carbon supported MoS2 NFs confirmed a distinct Faradic characteristic. The VS2 nanosheets (NSs) and carbon supported VS2 NSs were also effectively synthesized via hydrothermal method. The SEM micrographs for VS2 NSs and carbon supported VS2 NSs samples reveals level increased. Furthermore, SEM-EDX analysis have confirmed the presence of V and S as well as C and O on carbon supported VS2 nanocomposites, and it clearly shown a gradually blending as the ratios increases. The structural studies through XRD analysis have revealed peaks at 2θ angles of 15.4◦, 28.2◦, 34.2◦, 36.2◦, 43.3◦,48.3◦, 54.4◦, 57.7◦ and 66.2◦ which correspond to the lattice planes (001), (002), (100), (011), (102), (003), (110), (103) and (201) belonging to hexagonal VS2 (H-VS2) crystalline phase as per JCPDS card 36-1139. The HRTEM have revealed that the VS2 NSs have an edge to edge length of ~ 0.294 – 1.248 µm. Also, HRTEM micrographs of VS2 NSs have revealed interplanar d spacing of 0.571 nm belonging to the (001) lattice plane of hexagonal VS2 (H-VS2) structure. FTIR analysis have shown a peak at 558 cm-1 attributed to V-S which is evident that sulfur has bonded with the metal (V) and is in agreement with EDS. CV, CD and EIS measurements have shown that the ratio 1:8:1 is more superior to VS2 NSs and other carbon supported VS2 NSs. Based on Rreduction for the carbon supported nanosheets VS2 nanosheets are ordered as 1:8:1>3:6:1>6:3:1>8:1:1. Carbon supported VS2 NSs of the mole ratio 1:8:1 showed a small resistance of 0.32 Ω. This is further evidence that the carbon supported VS2 NSs of the mole ratio 1:8:1 in addition to revealing excellent catalytic behaviour is also more chemically stable and has good conductivity properties._________

- Description: Cases recorded with high blood pressure are a major concern in both public and private hospitals. Adequate provision of health information of patients relating to high blood pressure in Eastern Cape Hospitals hinges so much on the outcome of statistical analysis results. The usual statistical methodologies become inadequate in handling statistical analysis of data collected due to incomplete patients’ information stored in the hospital database. From time to time, new methods are developed to address the problem of missing data. High blood pressure is linked to a lot of diseases such hypertension, cardiovascular disease, kidney disease and stroke. In this study, we developed a new method for addressing the problem of missing data in assessing model used for estimating missing values in terms of minimum errors(using RMSE, MAE, and SE) and goodness-of-fits(using 2 R and adjusted 2 R ) of this model and P-value. . The study compared six different methods: Original data (OD), Listwise deletion (LD), Mean imputations (MEI), Mean above (MA), and Mean above below(MAB) and two steps nearest neighbour (2-NN).The comparison was performed using original data set, and missing values at 5%, 10%, 20%, 30% were simulated on Framingham risk scores under MCAR and MAR simulation on BMI values given some assumptions. Five performance indicators were used to describe the model minimum errors and goodness of fit for all the methods. The results showed that the 2-NN is the best replacement method at lower levels (5% and10%) of missing values while MA and MEI performed best at higher levels(15% and 20%) of missing values. All comparison was based on estimates closest to those of the original data where no value was missing. MAR results showed that 2-NN performed better than LD,MA,MAB, and MEI at 5%,10%, and 20% levels of missing data in terms of absolute difference in p-value to original data.

- Description: Implementation of an ecosystem-based management approach for marine systems requires a comprehensive understanding of the biophysical marine environment and the cumulative human impacts at different spatio-temporal scales. In Algoa Bay, South Africa, this study describes the epibenthic communities occurring in unconsolidated marine habitats. It further investigates the potential abiotic factors that influence their distribution and abundance, compares epibenthic communities with existing habitat information and evaluates the protection status of the marine environment in the Bay. Seabed imagery, covering a total area of 171.4m², and sediment samples were collected from 13 stations from which 106 epibenthic species were identified. Multivariate analyses revealed two statistically distinct communities that did not align with the Algoa Bay benthic habitat types defined in the current National Biodiversity Assessment (NBA, 2012). Further assessment indicated that community differences were driven by the presence of rock substrate. A range of abiotic factors were tested against the epibenthic communities to explore patterns and identify potential drivers. The combination of abiotic factors depth, mean grain size, mean bottom temperature and mean bottom current explained 55% fitted variation in epibenthic data. The degree of long-term variability in several of these parameters were likewise identified as explanatory variables, including bottom temperature, current speed and dissolved oxygen. The link between abiotic factors and the epibenthic communities observed indicate that these variables can act as surrogates for habitat mapping in the future. The existing and proposed Marine Protected Area (MPA) in conjunction with the NBA 2012 habitat types does well in protecting the majority of habitats in the Bay, however there remain habitats that lack protection. Utilising the benthic communities and potential drivers identified in this study, the proposed MPA boundary delineations should be somewhat altered to include missing habitat types.

- Description: The world is experiencing strange weather conditions which have, arguably not been experienced before. Some parts of the world are experiencing severe drought, other parts are receiving above normal rainfall associated with violent cyclones. The changing environmental conditions are perceived by environmental scientists as the consequences of climatic change that has been triggered by global warming which has been largely attributed to an increase of greenhouse emissions due to human activities such as transportation, industry and energy production. Sub-Saharan Africa contributes the least greenhouse gas emissions in the world but it is unfortunate that the region is suffering most from the perceived impacts of climatic change. The region has been experiencing prolonged drought conditions that have negatively impacted food production and it is projected that millions will suffer malnutrition and starvation in future if the perceived causes of climatic change are not addressed. This research seeks to make an in-depth analysis on the perceptions of climatic change and food insecurity in Buhera district east of Zimbabwe. The researcher used interviews and observations to gather firsthand information from a diverse number of participants. The findings of this research largely drew upon the Sustainable Livelihood Framework as a lens for interpretation. The results of this research indicate that there is less food available in Buhera due to poor crop production; perceived to be as a result of the changing climate

In carrying out this study, four research objectives with thirtyseven (37) research questions were posed. Purposive Sampling was employed to sample 30 Administrative support staff. The instruments used for data collection were questionnaire and face to face interview. Twenty-nine (29) questionnaires out of the thirty (30) returned completed and five senior managers were interviewed face to face. Descriptive statistic was used to analyse the research questions on the questionnaire and thematic approach was used for analysing the response from the interviews. The major findings of the study revealed WSU fell below the requirements in terms of records management programme on maintaining records that document its business activities. Inadequate infrastructure, inadequacy regarding the desirable control of WSU records at each stage as required by the records life cycle framework was also found to be inadequate and limited knowledge of legal requirements regarding records management. Based on these findings, the following recommendations were made. Effort should be made to implement a Centralised control of Decentralised Registry System (Integrated Registry System), provision of training of staff, as well as proper infrastructural facilities.

- Description: While parental involvement in homework is significant, few parents are able to assist in rural communities. The purpose of this study was to investigate the way parents and/or caregivers in rural communities are involved in the homework of their children. The main question was to find how parents in rural communities get involved in homework. The study adopted an interpretive paradigm, a qualitative approach, and a case study design to guide data collection and interpretation. Data was collected in two public combined schools in the King William’s Town District of the Eastern Cape Department of Education (ECDoE). One-on-one semi-structured interviews were used to collect data from parents, educators and principals whilst focus group interviews were used with learners. Documents were collected for background context of the schools. Documents collected include the school journals, learner portfolios, staff establishment, and school timetable. Schools were chosen purposefully because of their rural context and convenience to the researcher. Purposive sampling was also used in the selection of participants. To enhance the trustworthiness of the study, data sources were triangulated, participants were allowed to use their own language, data was mechanically recorded and transcribed and verbatim quotes were used in analysing data. The study found that all participants in both schools supported the need for parents to be involved in homework. Educators, largely, had a pessimistic view about parents; they felt that the parents do not meet their expectations in terms of assisting learners with homework. The study found that although parents see the need for their involvement in homework, in reality they are not always involved. Those parents who are able to assist with homework use a variety of strategies like assisting with the actual homework, referring their children to those who can assist, monitoring and supervising, assisting financially, and organising infrastructure. The study also found that there are several challenges facing parents in rural communities that hinder them from assisting optimally. These include negative attitude towards homework, lack of subject knowledge, irresponsibility, lack of finances and material resources, community commitments, not having enough time, family responsibilities, lack of commitment by learners, and homework overload. These challenges suggest that many parents in rural communities may not be able to provide the necessary leadership for modelling purposes to learners. This can be attributed to several exogenous and exogenous factors that have an impact on homework completion by learners. This study, in addition, found that participants have a good sense of what can be done to improve parental involvement in homework. These include the revival of Adult Basic Education (ABET), the need for integrated efforts by Non-Governmental Organizations (NGOS), government departments, schools, and community organizations to improve infrastructure in rural communities, have awareness campaigns on the significance of parental involvement, provision of access to Information Communication Technology (ICT), establishment of homework support groups and quiz clubs, provision of incentives for parental assistance, and reduction of child labour.

- Description: Forest protected areas (FPAs) constitute one of the main strategies for achieving the triple benefits of biodiversity conservation, livelihoods sustenance and climate regulation. The quality of FPA governance plays a major role in the achievement of these conservation objectives. Governance encompasses policies, institutions, actors, processes and power and how they interplay to determine conservation outcomes. Currently, no research has systematically explored the historical and contemporary governance of Zimbabwe’s protected indigenous forests and its implications on forest condition and local communities’ livelihoods. This is despite the fact that improving forest governance depends on learning from those that prevailed in the past as well as those currently obtaining on the ground in terms of how they have performed in relation to conservation and livelihood sustenance. This study assessed Zimbabwe’s historical and contemporary FPA governance and its implications on social and ecological outcomes. The overall rationale of the study was to provide evidence of the impact of past governance arrangements on forest condition and local communities’ livelihoods, improve understanding of the current governance arrangements and propose future FPA governance strategies and mechanisms to enhance conservation and local communities’ livelihood outcomes. Accordingly, the specific objectives of the study were to: 1) characterize and collate historical governance of FPAs in western Zimbabwe, 2) evaluate the impact of governance on forest condition and local communities’ livelihoods, 3) explore the nature of contemporary governance at the forest level, and 4) propose the governance model for Zimbabwe’s FPAs into the future. The study employed a combination of quantitative and qualitative data collection and analysis methods including the systematic literature review methodology. Using specific case studies of indigenous FPAs in western Zimbabwe as examples, the study initially evaluated through literature review (Chapter 2) the history of forest governance in Zimbabwe showing how four main powers (force, regulation, market and legitimation) led to different types of local community exclusion and how community agency countered exclusion especially from the year 2000 to date. Chapter 3 uses six case study forests to assess the quality of historical FPA governance by analyzing the application of seven governance principles. The results showed that the quality of governance was high during precolonial times, deteriorated with the inception of colonialism and remained poor after independence in 1980. Forest condition also varied in tandem with the quality of governance variations showing a positive relationship between the two variables. Participation in decision making, fairness in sharing benefits and effective rule enforcement emerged as key principles for FPA authorities to earn local community support and improve forest condition. Chapter 4 employed remote sensing techniques to determine the impact of governance on FPA land cover change by comparing FPAs with in situ and ex situ inhabitants. Results revealed that there was a significant relationship between governance quality and land cover change. FPAs with in situ inhabitants experienced higher forest loss than those with ex situ inhabitants. Poor governance accelerated forest conversion to other land uses particularly agriculture and settlement. Chapter 5 explored contemporary FPA governance at the forest level. Results showed that human agency that led to the invasion of FPAs from the year 2000 onwards disrupted the governance arrangements that were previously in place subjecting Zimbabwe’s FPAs to near open access by local communities and other actors. The FPAs’ contemporary governance is characterized by involvement of multiple actors with diverse interests, lack of Forestry Commission legitimacy, very low levels of local people’s participation in decision making and rule enforcement, lack of compliance with FPA rules and actual benefits that do not match local communities’ expectations. Overall, the study has revealed the ineffectiveness of the conventional centralized FPA governance in achieving positive conservation and local communities’ livelihoods outcomes. The study recommended a shift from conventional centralized governance to pro-people adaptive collaborative management (ACM). This has the potential to address most of the governance ills affecting Zimbabwe’s FPAs if it is designed and implemented with the full commitment of all relevant actors. This governance approach should, however, avoid some of the pitfalls such as elite capture, corruption in benefit sharing, gender inequality and technocratic professional management approaches that have characterized some collaborative governance systems in developing countries further perpetuating marginalization and poverty amongst local communities. Forestry Commission must also exercise visionary leadership and motivation. ACM becomes possible through leadership, vision, establishment and maintenance of links through culture and management and high levels of motivation. Designing and implementing ACM avoiding the highlighted pitfalls improves the capacity of the FPAs to continue providing social and ecological benefits such as improvement of local communities’ livelihoods, biodiversity protection and climate change mitigation.

- Description: Forest protected areas (FPAs) constitute one of the main strategies for achieving the triple benefits of biodiversity conservation, livelihoods sustenance and climate regulation. The quality of FPA governance plays a major role in the achievement of these conservation objectives. Governance encompasses policies, institutions, actors, processes and power and how they interplay to determine conservation outcomes. Currently, no research has systematically explored the historical and contemporary governance of Zimbabwe’s protected indigenous forests and its implications on forest condition and local communities’ livelihoods. This is despite the fact that improving forest governance depends on learning from those that prevailed in the past as well as those currently obtaining on the ground in terms of how they have performed in relation to conservation and livelihood sustenance. This study assessed Zimbabwe’s historical and contemporary FPA governance and its implications on social and ecological outcomes. The overall rationale of the study was to provide evidence of the impact of past governance arrangements on forest condition and local communities’ livelihoods, improve understanding of the current governance arrangements and propose future FPA governance strategies and mechanisms to enhance conservation and local communities’ livelihood outcomes.

- Description: Since the dispensation of the democracy in 1994, the South African labour market has been inclusive to the race that previously was excluded in certain positions in the private sector. Black professionals, managers and senior managers have since increased in the market and they became in demand due to the introduction of the Equity laws by the government of South Africa. The purpose of this study was to investigate the reason why black professionals do not stay or develop loyalty with the private sector organisation that employ them within the Nelson Mandela Bay region. Factors that could affect the reason to stay or not with these private organisations were identified and researched. These factors are, Employment Equity, Career Development, Diversity Management, Trust, Transformation and Management Style. Literature review on the views of scholars about these factors was done. A questionnaire to investigate these factors was distributed to black professionals that still work for the private organisations in the Nelson Mandela Metro and to the ones that opted not to stay. Interviews were also conducted with the professionals that are specialists in the field of human resources. The following are the main findings of the study. Racial prejudice towards black professionals is evident in these organisations. There is lack of equity and affirmative action is not implemented properly, which assists in the decision not to stay with these organisations. Career development is determined by race, meaning those who are developed are chosen by their race. The lack of career development is also perpetuated by the lack of proper strategies and the respondents feel that these strategies need to be reviewed. The lack of career development also contributes to the decision whether to stay or not. Trust between the black professionals and their superiors is not a problem. The black professionals are happy with how their superiors support them and how they reward them. Racial discrimination plays a role in the superior’s ability to manage diversity and this also contributes in the decisions whether to stay or not with private organisations. The lack of the diversity management influenced by racial prejudice, gives enough reasons to the black professionals to leave the organisations. Lack of transformation is evident. It seems that black professionals are only given manager or senior manager positions only to comply with the laws of the country. The respondents seemed to be happy with the management style of their superiors.

Olu phando lugxile kakhulu kwincwadi kaTamsanqa ethi ‘Buzani kubawo’ nekaQangule ethi ‘Amaza’. Kuyafumaniseka ukuba ungquzulwano kwezi Drama zimbini lwenziwe kukudibana kwenkcubeko yaseNtshona neyemveli, zangquzulana. Abalinganiswa bamacala omabini baye banezinye iingqondo ezingahambelaniyo nelinye icala. Abalinganiswa abaziintloko bezi Drama zombini (ulutsha) bakholelwa kwinkcubeko yaseNtshona, babe abazali babo bona bekholelwa kwinkcubeko yemveli. Naxa abantu benkcubeko yemveli babeqhubeka nenkcubeko yabo yemveli, babengayithandi inkcubeko yaseNtshona eyamkelwe ngabantwana babo, ebenza ukuba bayijongele phantsi inkcubeko yabo yemveli. Apha ndizama ukuveza ukuguquka kwamaxesha ngenxa yefuthe laseNtshona okudale uqhankqalazo, ungquzulwano novukelwano phakathi komzali nomntwana nendlela oku kudala ngayo iyantlukwano ekuhlaleni naphakathi kwesizwe siphela.

- Description: This study focuses on two roll-outs of a, year-long National Qualification Framework (NQF) level 5, environmental education learnership in South Africa and attempts at enhancing collaborative learning at workplaces using a familiar social networking site called Facebook. This study uses the Facebook group sites created for the workplace course component of the course as one of the means of data collection. Additional interviews and focus groups with learners and administrators on both Environmental Education Training and Development Practices (EETDP) courses also informed the study. The study is located within the context of the rise of the information age, its effects on socio-ecological landscape at large and ways of using social networking sites in order to facilitate scaffolding and meaning making within zones of proximal development for environmental education learnerships. It also looks at the model of apprenticeship and workplace based learning as it is broadly located at the nexus of the SAQA-led academic inquiry into workplace based learning and professional development. It was found that the use of Facebook on the EETDP learnership allowed for collaborative learning to take place between peer to peer interactions as well as between tutors and learners. It was also noted that scaffolding processes requires both technical assistance and strong instructional input from course tutors. One of the most important findings in terms of collaborative learning and engaging within the Zone of Proximal Development (ZPD) was that learners were able to communicate more effectively and freely with both fellow learners and tutors on course after participating on the Facebook group sites. The study offers recommendations on how a social networking platform like Facebook can be utilised effectively for environmental education. The study recommends that scaffolding of workplace based tasks and concepts needs to be better integrated with the course and in both online and offline interactions between learners. It also illustrates how social networking sites can become powerful tools for creating meaning making when combined with course work.

- Description: This thesis examines the agricultural labour process on commercial farms in post-apartheid South Africa with a particular focus on systems of labour control on these farms. Considerable literature exists about the labour process in capitalist society but the capitalist labour process does not exist in any pure form. Rather, different labour processes exist and the specific form they take depends on spatial and temporal conditions. Additionally, labour processes are often economic sector-specific. Because of variation in capitalist labour processes, differences in systems of labour control (or labour control regimes) also arise. Historically, up until the end of apartheid in 1994, the labour control regime on commercial farms in South Africa was marked by a paternalistic despotism of a racialised kind. This in part reflected the fact that commercial farms were simultaneously sites of both economic production and social reproduction and, further, they were very privatised agrarian spaces largely unregulated (specifically with regard to labour) by the state. Since the end of apartheid, commercial farms have been subjected to multiple pressures. Notably, the South African state has strongly intervened in labour relations on commercial farms, and commercial farms have been subjected to ongoing neo-liberal restructuring. This has led to the prospects of changes in the prevailing labour control system on commercial farms. In this context, the thesis pursues the following key objective: to understand changes and continuities in the labour process on commercial farms – and particularly labour control systems – subsequent to the end of apartheid in South Africa. It does so with reference to four farms in Eastern Cape and KwaZulu-Natal Provinces.

This in part reflected the fact that commercial farms were simultaneously sites of both economic production and social reproduction and, further, they were very privatised agrarian spaces largely unregulated (specifically with regard to labour) by the state. Since the end of apartheid, commercial farms have been subjected to multiple pressures. Notably, the South African state has strongly intervened in labour relations on commercial farms, and commercial farms have been subjected to ongoing neo-liberal restructuring. This has led to the prospects of changes in the prevailing labour control system on commercial farms. In this context, the thesis pursues the following key objective: to understand changes and continuities in the labour process on commercial farms – and particularly labour control systems – subsequent to the end of apartheid in South Africa. It does so with reference to four farms in Eastern Cape and KwaZulu-Natal Provinces.

- Description: Cruise holidays from Durban Harbour to Mozambique and Mauritius have been popular for many years but have increased dramatically in recent years. Due to the encroaching industrial development of the terminals location, the experience of arrival to the current passenger terminal is one of being exported (human trafficking), as opposed to that of going on holiday. This image is enhanced by passengers sitting on cheap plastic chairs while they wait for their number to be called. After which they journey through a series of makeshift partitions before standing in front of a photograph of the ship to have a photograph taken. This causes a rather depressing boarding process and the traveller only begins to experience the holiday vibe once on board the ship.

- Description: This project investigated how to develop a mobile intervention to support medication compliance for patients with chronic and acute diseases. Chronic diseases cannot be cured but can be controlled, usually by taking medication every-day. Therefore, it is very crucial for a patient with a chronic disease to take their medication on time to prevent complications or negative impact on their health. Due to the widespread use of mobile phones, having an automated mobile mechanism to remind patients to take medication is regarded as an effective way of supporting medication compliance. The focus of the research was on investigating how mobile health applications can be used to support patients with chronic and acute diseases in South Africa. Literature identified that medication compliance is low and that a need exists for an intervention to increase compliance. The main goal of this research was to produce a mobile health application to assist medication compliance and support patients with chronic and acute diseases in South Africa and investigate its perceived usefulness. The project made use of two field studies to substantiate its results. The first field study involved patients with chronic diseases and the second one involved patients with acute diseases. The feedback from the first field study and from a literature review was used to redesign the mobile application. The project also investigated the attitude of patients taking medication over a short period of time as well as how such patients compared with those taking chronic medication. The project identified the benefits and disadvantages of using an m-health application to support medication compliance based on the participants’ feedback and behaviour observed in using the application.

- Description: Challenges of access to education in the developing world and elsewhere appear to be widespread. Many declarations and conventions have been developed to assist countries to respond to the issue. While challenges of access are universal, Africa in general and sub-Saharan Africa in particular are presented with additional concerns about gender equality and gender parity. While learner numbers seem to be on the decline globally, dropout amongst girls is disproportionately greater than amongst boys. Even though school retention presents a challenge at all levels of the schooling system, it is more acute for girls at the secondary school level. This study was conducted to examine and understand factors that shape retention of secondary school female learners in two rural public schools in Alimosho Region of Lagos State, Nigeria. The study design was qualitative and interpretive in nature. Data collection strategies included administered questionnaires in two schools, focus group discussion with twenty female learners in two schools, case studies, individual interviews with four participants from two schools, and observation in English and Biology classes where the two teachers from the two schools participated in the interviews. Ethical clearance from Alimosho Educational Region office and the two schools was obtained before undertaking the study. Participants’ school principals also signed written consent forms before interviews. The female learners were briefed about the study interview activities and advised that their participation was voluntary and that they were free to withdraw at any point. This study drew on Sen’s (1989, 2000) capabilities theory to understand the phenomenon beyond dominant discourses on education that view education as a basic human right or that focus on economic and development gains. The key finding of this study is that in-school and out- of- school factors interact in complex ways to support female learner retention. Key among these are value placed on education by female learners and significant others, particularly parents; family support; and individual aspirations. Extra-curricular participation, government policy, role models, and peer support were also found to be important factors that mediate progression and retention.

- Description: Social media is fast becoming an ever-increasingly significant part of the world of business and a phenomenon which cannot be evaded. The advent of social media in the workplace compels organisations to acclimatise to the transformation emanating from employees‟ adoption of these technologies (Hanaki & Casella, 2008). Approximately seventy percent of organisations do not have a social media governance framework in place (Fink et al., 2011). Social media governance in organisations is very disjointed; companies have varying stances as to social media strategy, the risks, benefits and business use of social media (Thompson et al., 2011). The growth of social media and its use in the business environment will see a more standardised approach to social media governance (Thompson et al., 2011). Being at the forefront of technology development in Africa, and in certain areas, globally (Government of the Republic of South Africa, 2012), places added emphasis on IT organisations in South Africa to set the standard as it relates to social media governance. The diversity and depth of the human and technology resources within these organisations, creates an environment conducive to establishing and pioneering sound social media governance structures. The treatise consists of a study on the governance of social media and the successive development of two frameworks; an integrated framework for the governance of social media in the workplace, as well as integrated framework for a social media policy within an IT organisation. These frameworks are empirically evaluated amongst employees, within the context of Information Technology (IT) organisations, in South Africa. Several recommendations are proposed by the author in relation to the adoption of the proposed frameworks.

- Description: Sudan is located in the Northern part of the African continent and has a total land mass of 2.5 million square kilometres, with an estimated population of about 39.15 million people.1 Before the secession that established the South as an independent state from the North, Sudan was the largest country on the continent and hitherto was administered as a colony under the British mandate. From 1898 the United Kingdom (UK) and Egypt administered Sudan as an Anglo-Egyptian territory but North and South Sudan were administered as separate provinces of the condominium.2 In the early 1920s, the British passed the Closed District Ordinances which stipulated that passports were required for travelling between the two zones. Permits were also required to conduct business from one zone to the other, and totally separate administrations prevailed.3 However, in 1946 the British administration reversed its policy and decided to integrate North and South Sudan under one government. The South Sudanese authorities were informed at the Juba Conference of 1947 that they will be governed in the future under a common administrative authority with the north.5 From 1948, 13 delegates nominated by the British authorities represented the South in the Sudan Legislative Assembly. Many Southerners felt betrayed by the British as they were largely excluded from the new government. To them, it was a strategy by the British aimed at protecting their interest as far as colonial legacy is concerned.6 They complained that the language of the new government was Arabic and they were under represented. Of the eight hundred positions vacated by the British in 1953, only four were given to the Southerners. The political structure in the South was not as organized as that in the North and for this reason, political groupings and parties from the South were not represented at the various conferences that established the modern state of Sudan. As a result, many southerners did not consider Sudan to be a legitimate state. Although the Sudanese state was considered illegitimate by the Southerners, the Sudanese parliament unilaterally declared Sudan’s independence on 1st January 1956.8 Subsequently, the Arab-led Khartoum government reneged on promises it had made to Southerners to create a federal system. This led to a mutiny led by Southern army officers and sparked off a civil war after independence in 1956.9 Besides the issues highlighted above, the Abyei region of Sudan is rich in natural mineral resources and has been a bone of contention between the North and South. It has also affected Darfur negatively as most of the rebel groups involved in the Darfur conflict, like the Sudan Liberation Movement (SLM) and the Justice and Equity Movement (JEM), also seek for a share in the wealth of the region.10 However, before the June 2011 referendum, the UN Secretary-General, Ban Ki-moon called for the Sudan to withdraw all police officers from the Abyei region of South Sudan.11 Although the referendum resulted in the Republic of South Sudan, separating it from the North which remains the Republic of Sudan, political views expressed by the provinces in the North region have further captured more attention from the international community.12 The quest for Arab domination is common in this area and, one among the leading regions that have fallen prey to this practice is Darfur

- Description: This study was conducted in Grahamstown in the Eastern Cape, South Africa. It is a qualitative case study located within the interpretive paradigm and was carried out over a period of a year. The theory implicit in the interpretive paradigm is of human beings as interpreters and constructors of a meaningful world. Thus, the focus of this study was on investigating the benefits of indigenous ways of knowing about wild food plants (imifino) in conjunction with hands-on activity-based lessons. This was done with the view to promote a conceptual understanding of nutrition and conservation in the Natural Sciences. The transformation of the school curriculum in South Africa called Curriculum 2005 (C2005) underpinned by the outcomes-based education (OBE) philosophy also triggered this study. The C2005 and OBE emphasise that learners’ prior everyday knowledge should be taken into account during the teaching and learning processes. The intention of the curriculum is to promote the idea of grounding knowledge in local contexts, while being sensitive to global imperatives. Although the acquisition of western knowledge has been and still is invaluable to all, on its own, it has been incapable of responding adequately to modern society in the face of massive and intensifying disparities, untrammeled exploitation of resources, and rapid depletion of the earth’s natural resources. Essentially, indigenous knowledge systems represent both a heritage and resource that should be protected, promoted, developed and, where appropriate, conserved. It is a resource that should serve the present and succeeding generations as many people’s cultural practices still rely on the use of wild plants. Within this context it should be borne in mind that the overexploitation of natural resources threatens not only biodiversity but also local traditional knowledge systems and ultimately cultural heritage; and research has a role to play in this regard. The research process in this study evolved into two main phases. The initial phase involved mobilising Grade 7 learners’ prior everyday knowledge on wild food plants (imifino). This led to the second phase of the research project, which was aimed at developing concepts through three hands-on activity-based lessons. I invited a community member to give a lesson on what imifino is and how to collect and prepare it, with the belief that the involvement of parents and community members in learners’ education can help bridge the gap between everyday life and school science. It is for these reasons that I believe that the constructive perspective can provide an appropriate methodological framework, conceptual structure and terminology for analysis of teaching and learning activities on the use of wild food plants in this study. The data generation techniques used in this study were questionnaires, observations and interviews (semi structured and focus group). A wide range of data generation techniques were employed to crystallise and validate the data generated using triangulation. The results from the analysed data revealed that consideration of indigenous ways of knowing in conjuction with hands-on practical activities enhanced interaction and learning among the learners. Also, linking of scientific knowledge to learners’ everyday lives was useful in fostering meaning-making and conceptual development.

- Description: The 1980s and 1990s saw major changes in the political landscape of the media in many countries that were either reverting or emerging from repressive nondemocratic regimes. Among the notable changes in media industry was the opening up of the national airwaves, which had been a state monopoly, to private sector and community participation. The democratic dispensation also put state broadcasters in the spot-light regarding their editorial content which was previously ‘institutionalised’ as belonging to the ruling regimes. This study set out to investigate the extent to which broadcasting reform legislation meant to address the unfair coverage of contending voices on Zambia’s public broadcaster has had an impact in reversing the situation in the newsroom. Using qualitative methods of investigation, the study established that while the ZNBC staff understand aspects of their role in their newsroom in relation to the principles of public service broadcasting and in line with the enacted legislation, they perceive that, in practice, they have to ensure that the news content still remains a reserve of a few voices in favour of the ruling regime. This was evidenced by testimonies from the news staff’s complaints of continued editorial interference in their work by government leaders and government appointed gatekeepers, as well as selfcensorship. The study recommends, among other things, the full implementation of the recently enacted laws on the operations of ZNBC in order to achieve some minimum levels of being a public broadcaster. It further recommends a serious re-orientation of the ZNBC newsroom and management staff to the current legislative requirements so as to shift their mindset away from their traditionally-held views of thinking that news at that station is only for the ruling regime.

It further recommends a serious re-orientation of the ZNBC newsroom and management staff to the current legislative requirements so as to shift their mindset away from their traditionally-held views of thinking that news at that station is only for the ruling regime.

- Description: The use of the Web to carry out business on the Internet has become a viable option in all business sectors, and Internet banking in South Africa is no exception. The nature of business on the Internet in South Africa and the World is investigated. The extent of Internet banking in South Africa is ascertained and the expectations and perceived problems of online bankers are discussed. The importance of Human Computer Interface and Web Interface Design for successful business is promoted with a discussion of their guidelines and principles. Web Evaluation techniques and Tools are assessed and The "Gartner" Web evaluation tool is selected to evaluate the three bank Web sites. The results of the evaluation indicate that there are several generally well implemented design criteria used by all of the banks while some criteria are not implemented at all. Each bank is discussed individually to identify strong and weak features of their Web site design. Essential aspects of Web design have been proposed for inclusion during the design of "online" Banking Web sites.

Biology and demography of the spotted grunter Pomadasys commersonnii (Haemulidae) in South African waters

- Description: The spotted grunter, Pomadasys commersonnii (Haemulidae), is an Indian Ocean coastal species, extending from India to False Bay but is absent from the central Indian Ocean islands. Its taste and texture has made it one of the most important line fish species and is caught by recreational and subsistence fisherman along the entire east coast of South Africa. Because of its inshore distribution, reduced catch rates and estuarine dependence the species was de-commercialised in 1992. Since then it has been investigated as a candidate species for mariculture. All previous work on the biology of the species was undertaken on fish collected in KwaZulu-Natal in the mid 1970's. All other information has been incidental and formed part of other ecological studies. All management plans for this species have been based on these data. To develop a more comprehensive management plan that incorporates the entire population of spotted grunter, it was deemed necessary to reassess the biology (including feeding biology, age and growth and reproductive biology) as well as the demography of the population throughout its distributional range in South African waters. Analysis of the diet of spotted grunter, collected in estuaries, indicates that crustaceans form the bulk of the prey selected. Amphipods, mysids and estuarine brachyura predominate the diet of fish < 300 mm TL. At 200 mm TL fish start to prey on anomurans, which are extracted from their burrows using the 'blowing' feeding mechanism. Anomurans, in particular Upogebia africana and Callianassa krausii, become the preferred prey of fish larger than 300 mm TL. The high degree of diet flexibility that spotted grunter exhibit means that the composition and abundance of the macrobenthos of a particular environment will dictate the diet of the species. Otolith growth zones were found to be deposited annually with the opaque zones being deposited during the austral summer (November - February). The optical definition of annual otolith growth rings differed significantly between geographic regions (namely: Western Cape, South Eastern Cape and KwaZulu-Natal). Growth (sex combined) offish in the Western Cape were best described by the specialised 3 parameter Von Bertalanffy with a relative error structure in the form : Lt = 753(1- e⁻°·¹⁵⁴ ⁽t +¹·⁶¹⁵⁾) while growth in the South Eastern Cape was best described by using the Schnute model with an absolute error structure in the form: Lt=177°·⁴¹⁶ + (676.2⁻¹·²⁶⁶ - 169.2⁻¹²⁶⁶)[1-e°·⁴¹⁶⁽t-t₁⁾ / 1-e°·⁴¹⁶⁽t₂-t₁⁾]¹/¹·²⁶⁶ whereas growth was best described in KwaZulu-Natal using the specialised 3 parameter Von Bertalanffy with a relative error structure in the form: Lt = 839(1-e°·¹⁷⁽t⁺°·⁴⁹⁾) In the South Eastern Cape, length at 50% maturity was found to be 305 mm TL for males. Since females with ripe & running or spent gonads were not found in the South Eastern Cape and since histological evidence suggests that females in the South Eastern Cape have spawned, it appears that spawning does not occur in the South Eastern Cape. These results suggest that adults are resident in the estuaries of the Western and South Eastern Cape and undertake the spring/summer, northward spawning migration to KwaZulu-Natal. After joining the resident spawner stock in KwaZulu-Natal and spawning in the offshore environment of KwaZulu-Natal, adults soon return to the southern regions of their distributional range. Juveniles recruit into KwaZulu-Natal estuaries at a length of 25 - 35 mm TL. A proportion of the eggs and larvae are transported southwards along the periphery of the western boundary Agulhas Current where juveniles (25 - 30 mm TL) recruit into the estuaries as far south as the Swartvlei estuary in the Western Cape. There is evidence to suggest that the fish, which occur in the Western Cape estuaries, have migrated there once they have attained sexual maturity further east.
