- Description: Considering the backward and forward linkages, the agro-industrial sector contributes about 12 percent of South Africa‘s GDP, and employs approximately 8.5 million people. In the Eastern Cape Province, the sector contributes about 1.9 percent of the Provincial GDP, and over 3 million people derive their livelihoods from subsistence smallholder farming. Despite its importance, agricultural productivity has stagnated for several years across the Eastern Cape rural communities. There have been several attempts by the government to improve the agricultural productivity on smallholder farms since the end of apartheid, especially through the establishment of small-scale irrigation schemes, subsidization of farm inputs, and provision of credit facilities and enacting a number of land reform policies. In spite of the government support, most rural communities like Qamata and Tyefu are still faced with high levels of poverty affecting 76 percent and 91 percent of the population, respectively. This research evaluated the current smallholders‘ production efficiency, and the link between smallholder farmers‘ human dimensions (entrepreneurial spirit and positive psychological capital, goals and social capital, and other efficiency related variables) with production efficiency and household commercialisation index/level. The study used participatory approaches for site selection, sample selection and data collection. The analysis was based on both information from informal interviews and formal primary data collection. The Data Envelopment Analysis and Stochastic Production Frontier techniques were used to determine the relative efficiencies of individual farmers and to identify the major factors that influence the efficiency of production. Overall, 158 farmers were interviewed both at Qamata and Tyefu irrigation schemes. Descriptive statistics of this study indicated that most of the farmers were men with an average age of 61 years, and mean household size of 4 persons with the household head having at least obtained some primary school education. Farming is the major source of livelihood for smallholders with an average income of R4527.49 per crop season. Smallholders use improved seeds, fertilizers and tractor for ploughing with less use of pesticides and herbicides. Although smallholder irrigators generate more gross margins from maize and cabbage enterprises, generally both categories of farmers exhibited a low average household commercialization index for maize and cabbage at 0.41 and 0.22, respectively. Both Data Envelopment Analysis and Stochastic Production Frontier results indicate that farmers are about 98 percent technically efficient in maize and cabbage enterprises, respectively. However, farmers were allocatively inefficient as they were under-utilizing seed and pesticides while over-utilizing inorganic fertilizers. Factors that are positively associated with technical efficiency in maize production included household size, farming experience, off-farm income, use of agro-chemical; gross margins and commercialisation level of maize output. Determinants of technical efficiency in cabbage enterprise included farming experience, amount of land owned, use of agro-chemicals, group membership and gross margins accrued to cabbage sales. Farmers‘ human dimensions that could be more positively and significantly associated with production, efficiency and household commercialisation level included risk taking (hope), innovativeness (confidence) and optimism for entrepreneurial/positive psychological capital. Farmers‘ goals included self-esteem and independence, and only external social capital which were identified to be more positively and significantly associated with farmers‘ production efficiency and commercialization level. The transition from homestead subsistence to commercial oriented small-scale irrigation farming is inevitable since smallholder irrigators earn more incomes from maize and cabbage and are relatively food secure. However, the key policy options that must be considered to address inefficiencies and improved commercialization level to aid the transition include: agricultural policies geared toward attracting youth in farming, improved quality of extension services, speeding up the land reform process, and formation of cooperatives and participatory policy formulation that takes full cognizance of the farmers‘ human dimensions. Since farmers‘ human dimensions as defined in the literature and this study are not things that are amenable to direct policy intervention, they can only be modified indirectly through policy actions that affect their determinants. This means that a number of the demographic and socio-economic characteristics such as age, sex and education level of household head, farming experience, size of land owned, crop incomes, source of water for irrigation and location of the irrigation scheme that govern the way people perceive reality and respond to them must be the focus of concerted policy actions over the medium to long term.

- Description: The Malawi Government introduced the Performance Management System (hereafter referred to as PMS) in 2008 in an effort to enhance efficiency, effectiveness and productivity in the public service. However, since its introduction there have been indications that the system is encountering a number of challenges which are derailing and obstructing its implementation. This research was aimed at exploring those implementation challenges to PMS in the Malawi Civil Service with a case study of the Ministry of Education, Science and Technology (MoEST). Recommendations are made to the concerned parties for possible improvement in the implementation of PMS. The study took a qualitative approach whereby interviews with key informants, sampled purposively, were conducted in order to get relevant information to the problem. Besides the interviews, a study of official documents was done in accessing secondary data. The overall findings of the studyare that, although PMS plays a significant role in the improvement of productivity in an organisation, the Malawi government in general and the Ministry of Education, Science and Technology in particular, are failing to implement it effectively due to varying challenges that are generic to the entire Malawi Civil Service and also specific to the MoEST. The generic implementation challenges included: lack of correct understanding of the term performance management, design challenges and inadequate consultation, lack of linkage between rewards and performance, lack of leadership and management commitment, lack of knowledge and skills about the process and procedure of PMS, weak monitoring and evaluation (M&E) system, lack of clear legislation on PMS, lack of communication on organizational strategies,absence of performance standards, inadequate financial resources, attitude problem and social culture, political will not bending on performance and also the nature of the Civil Service. This research identified the following specific implementation challenges in the MoEST: inadequate sensitization and training on PMS, structural arrangements in the Ministry, numerous vacant positions and understaffing, unclear career path, duo lines of reporting, grade of employee determining the criterion of assessment, promotion interviews for teachers rarely happen, under qualified head teachers managing institutions, as well as administrative arrangements and political appointments to positions. The study upon giving recommendations to have the highlighted challenges addressed accordingly with a sense of commitment, concluded that the performance management system in Malawi Civil Service and MoEST in particular , while well-intentioned, is really fraught with numerous challenges that have adversely impacted on its implementation. At the individual level a lot of work has to be done in relation to making PMS being accepted. Most of the employees in the Malawi Civil Service and MoEST have little knowledge or none at all about the system as such effective implementation is failing to take place.

- Description: Since the dawn of democracy in 1994, South Africa has promulgated a number of progressive legislation and programmes in an effort to improve the well-being of its citizens. There is legislation and prescripts designed to provide policy and legal basis for a concerted and coherent pursuit of public participation in South Africa. There are various pieces of legislation that provide overarching principles and norms to guide the concerted enhancement of public participation in the local sphere of government. In spite of the plethora of policies and programmes, communities in various places continue to engage in service delivery protests. This study critically analyzed the implementation of public participation policy as a legislative core value for local government, with specific reference to Mbombela local municipality. In doing so, it critically explored the extent to which Mbombela local municipality involves the local communities in matters of local government such as in strategic decision making, the development of the IDP, performance management and in service delivery processes. The study employed a qualitative research methodology, relying mainly on secondary written sources of data, which reported on public participation and public administration. These sources include books, journals, internet sources, government legislation and policies. Data was also collected from Mbombela local municipality through interviews with municipal officials, members of ward committees, community development workers and the public. This study has found that Mbombela local municipality (MLM) relies primarily on ward committees, ward- based meetings and the Speakers outreach as mechanisms to facilitate public participation. The municipality seems to regard public participation as a crucial aspect in that a public participation unit was established; however the municipality is using a low level of participation, with limited power by citizens to influence strategic decisions. This means that communities and community organizations are involved on matters of the municipality only through attending community meetings therefore such meetings are not sufficient for effective public participation as communities should also be involved in more strategic and influential means such as participating in steering committees, development and economic forums. This study further found that some of the ward committees are not effectively functional as a result of lack of commitment from ward committee members, unavailability of some ard committee members due to their permanent job commitments and due to the difficulty that is caused by the vastness of some of the wards. This study also revealed hat there is no feedback provided to ward committees by the municipality on the ward committee reports that are submitted to the municipality on monthly bases, as a results some ward committee members are demotivated. This research study concludes that Mbombela local municipality is not effectively implementing local government legislation in respect to public participation.

- Description: Supply Chain Management was introduced in 2003 to government departments, municipalities and public entities as means of transforming public sector procurement practices. In some public institutions compliance with the regulatory framework has been limited to mere establishment of Supply Chain Management Units. Some of these units are not compliant with the National Treasury guidelines and are not properly staffed with personnel with the required skills and qualifications. Staff employed in Supply Chain Management units are either not provided with the required training in order to fulfill their employment obligations or do not see self-development in Supply Chain Management as of great importance. Supply Chain Management Policies do not evolve from within the institutions but more copies of the guidelines provided by the National Treasury. Staff do not get involved in policy development processes. This is a non-conclusive case study of the Eastern Cape Department of Roads of Public Works which is aimed at establishing the extent the department has complied with prescribed guidelines pertaining to establishment of Supply Chain Management, training of personnel and the development of policies and procedures on Supply Chain Management.

- Description: This study was done in order to assess the incidence of Staphylococcus species from milk of cows with subclinical mastitis and their antimicrobial sensitivity in some selected antibiotics and Usnea barbata lichen extracts. The study was conducted in two different commercial dairy farms. Staphylococcus species isolates were identified using several biochemical tests which included Gram’s staining test, catalase test and oxidase test. A commercial API® staph kit (bioMerieux, France) was used to confirm the bacterial organisms to their species level. The antimicrobial sensitivity of individual species was determined according to the Clinical Laboratory Standard Institute (CLSI) for the selected antibiotics. Agar well diffusion method and the broth micro-dilution technique were used to determine the sensitivity of Staphylococcus species in U. barbata extracts. A total of 467 milk samples were screened for bacterial identification from the two farms. Fifteen different Staphylococcus species isolates were identified from all milk samples that were examined. The most frequently isolated species included Staphylococcus xylosus (54.34%), Staphylococcus hominis (24.78%), Staphylococcus aureus (16.38%), Staphylococcus saprophyticus (16.12%) and Staphylococcus haemolyticus (11.63%). Most Staphylococcus species were resistant to Penicillin (75.35%), Nalidixic acid (72.55%) and Ampicillin (63%). Furthermore, the bacterial sensitivity evaluation of U. barbata lichen extracted with methanol and ethyl-acetate against selected Staphylococcus species isolates showed 92.31% and 53.85% susceptibility, respectively. The minimum inhibitory concentration (MIC) of the methanol and ethyl-acetate extracts ranged between 0.0390 to 10 mg/ml. There was a relatively high incidence of Staphylococcus species identified in milk of cows with subclinical mastitis from both farms. Conversely, Staphylococcus species isolates were resistant to antibiotics (mostly penicillin and ampicillin) commonly used in the farms. Furthermore, the study investigated the antimicrobial sensitivity of U. barbata extract in-vitro which may validate its use in traditional medicine for treatment of cows with mastitis.

- Description: Climate change has become a major concern globally and it clearly exerts a profound influence on the lives of poor rural populations who depend on agriculture for livelihoods.Generally, agriculture is more at risk from weather, pests and diseases than is industry or trade. Furthermore, many farming units are at low levels of development with little technological input in their production systems. This makes them vulnerable to any exposure to climate and environmental variation, given that there is little capacity for the system to adjust to change. Most at risk are the rural poor with low levels of development and limited ability to adapt to and overcome the effects of climate change. Using data from a sample survey of 120 households this study attempts to assess and compare indicators of vulnerability to climate change. The comparison was made at household level between three typical villages, an inland, a river catchment and a coastal village. This idea of comparison arises from the general understanding that different variables affect different regions differently so that the impact of and vulnerability to climate change differs across regions, areas and populations. The data was obtained using a questionnaire that was administered through face-to-face interviews. Given that sensitivity and adaptive capacity of farming systems to climate change is shaped by both socioeconomic and institutional factors, a multiple regression model was used to test the relationship between indicators of vulnerability and household socioeconomic and institutional characteristics. Indicators were selected based on significant statistical relationships. This means that the statistical procedure for selecting indicators involved relating a large number of variables to vulnerability in order to identify statistically significant factors. The results showed reliability of income and reliability of water resources to be good indicators of vulnerability. Many statistically significant variables as well as respective R2 of 0.988 and 0.825 confirm the foregoing. Another indicator was the Simpson index that measures diversification of agricultural production. The results show that vulnerability to climate change was highest for the households near the river and lowest for the inland village. Moreover, the results confirmed that most blacks that are practicing agriculture receive little if any support largely because available resources are highly skewed towards certain farmers rather than others.

This idea of comparison arises from the general understanding that different variables affect different regions differently so that the impact of and vulnerability to climate change differs across regions, areas and populations. The data was obtained using a questionnaire that was administered through face-to-face interviews. Given that sensitivity and adaptive capacity of farming systems to climate change is shaped by both socioeconomic and institutional factors, a multiple regression model was used to test the relationship between indicators of vulnerability and household socioeconomic and institutional characteristics. Indicators were selected based on significant statistical relationships. This means that the statistical procedure for selecting indicators involved relating a large number of variables to vulnerability in order to identify statistically significant factors. The results showed reliability of income and reliability of water resources to be good indicators of vulnerability. Many statistically significant variables as well as respective R2 of 0.988 and 0.825 confirm the foregoing. Another indicator was the Simpson index that measures diversification of agricultural production. The results show that vulnerability to climate change was highest for the households near the river and lowest for the inland village. Moreover, the results confirmed that most blacks that are practicing agriculture receive little if any support largely because available resources are highly skewed towards certain farmers rather than others.

- Description: Information is documented as data value in planning, decision making and evaluation of any programme, therefore any informed decision would be based on the kind of information that the decision maker has. Information seeking behaviour can be described as an individual’s manner of gathering and sourcing information for personal use, knowledge update and development. In the light of this Information, this study examined the information seeking behaviour of postgraduate students at the University of Fort Hare and Rhodes University. The study went further to understand the impact the introduction of new technology has on postgraduate students’ information seeking behaviour. The study was limited to postgraduate students in the faculties of Humanities, Social Sciences and Education at the University of Fort Hare and Rhodes University. These disciplines were selected because of Whitemire (2002:637)’s opinion that students studying humanities, social sciences and education carry out more information seeking activities than students studying hard sciences such as Mathematics and other Natural Sciences. The aim of the study was to establish how postgraduate students seek and gather information for academic use. The objectives of the study were as follows: to find out information sources that postgraduate students value the most and determine where they find such resources; to identify the activities postgraduate students engage in when seeking for information; to establish the factors which influence postgraduate students information seeking behaviour and to determine methods that postgraduate students use to obtain relevant information. Both quantitative and qualitative research methodologies were employed in a survey. The main research instrument was a questionnaire supported by focus groups and face to face interviews. The results showed that postgraduate students utilised different sources of information when seeking information for academic use. Internet usage however was established as the information source that postgraduate students valued and relied on most. Few respondents indicated that they still visited the library and browsed the shelves and found information that met their needs in books. Reports on consulting librarians for help were low. Although the study was not on information seeking behaviour and age, the researcher noticed that mature students did not make use of information technologies effectively and also called themselves “Born Before Technology” generation. The study also established that postgraduate student’s preferred or conveniently accessed Internet and other electronic sources of information in the libraries, even though the two Universities have postgraduate computer laboratories and students could also access electronic sources of information at their residences through wireless connection. The researcher also noted that postgraduate students relied more on lecturers and supervisors for the choice of information sources, rather than independently searching to find the most appropriate documents to use. Postgraduate students used keywords to obtain relevant information when searching electronic sources. The respondents strongly agreed that they felt frustrated, confused, disappointed and demotivated if they did not find relevant information for their searches. This validates Kuhlthau (1991)’s Information Seeking Process model (ISP) as it not only focuses on the information seeking process, but also on emotions, thoughts and expressions of the user when searching information. The study recommends the following: optional computer literacy programmes for postgraduate students, extended library orientation for postgraduate students, mentorship programmes, extended information literacy programmes, appointment of research and subject librarians as well as more faculty librarians and improvement in library marketing.

- Description: This study investigates HIV/AIDS coverage in selected South African newspapers. The rationale for the study hinges on the fact that the media’s role in informing society about social issues, such as HIV/AIDS, is of paramount importance. The study adopted, principally, the content analysis method and, as a supplement, discourse analysis. Four daily newspapers were content-analysed, namely: Daily Dispatch, Daily Sun, Sowetan and The Star. A total of 288 editions of newspapers, spanning a period of twelve months (January to December 2010) were sampled. This study is informed by agenda setting theory. Discourse analysis was used to determine the compliance of these newspapers to media guides on the use of appropriate language or terminologies. The tone, sentence structures used when disseminating HIV/AIDS stories were also examined. The results revealed that HIV/AIDS coverage by these newspapers is reasonable even though the prominence given to HIV/AIDS issues is dissatisfactory in terms of placement on the page, headline font-size and number of paragraphs devoted to HIV/AIDS stories. 5.0% of HIV/AIDS-oriented stories were placed on the front page; 93.8% on the inside pages while 1.3% were placed on the back pages. It was also found that news and feature were used equally to disseminate HIV/AIDS issues. These genres constituted 50% each. On the other hand, the results revealed a statistically non-significant relationship between the newspapers and categories; that is: (25.09 2 , p 0.122 0.05 ). Results further revealed that these newspapers used appropriate terminology and value-neutral language in their stories. The tone of the messages was found to be positive and encouraging.

- Description: PEP activity has been described in several locations and has mostly been linked to a variety of neurological disorders such as schizophrenia, amnaesia, depression as well as other disease states such as anorexia nervosa, bulimia nervosa and blood pressure regulation. The enzyme has also been previously isolated from a variety of archae, microorganisms and several eukaryotic species but no prolyl endopeptidases have been isolated from plants. Plants have high levels of proline and glutamine rich peptides in seeds. We therefore hypothesize plants must express PEPs during germination. Bioinformatics tools were used to identify known PEPs and putative plant PEPs. A global sequence alignment of putative plant PEPs and other known PEPs indicated that the active site amino acids Ser, His and Asp are conserved in putative plant PEP sequences. Furthermore, putative plant PEPs showed similar secondary structures to known PEPs and when a rice PEP was modelled onto porcine brain PEP structure, a high degree of similarity was found. Germination studies of wheat seed showed an increase of PEP activity over time with maximum PEP activity reached after 4 days of germination, which remained at this level until 9 days of germination, implying a function for PEP in plant seed germination. Wheat PEP was purified using ion exchange and gel filtration chromatography with a final yield of less than 1 percent and a relative purity (only 2 bands detected by SDS-PAGE). The purified wheat PEP had a molecular weight of approximately 55kDa, substrate specificity for chymotrypsin-like substrates (N-Suc-Ala-Ala-Pro-Phe-pNa, Km value of 0.58 mM, Kcat of 29.37 s–1; Kcat /Km 50813.14s–1 M–1); a pH optimum of 7.9; temperature optima of 37oC and a high sensitivity to temperature as indicated by loss of activity at temperatures above 40oC. Inhibition studies using E64, Leupeptin and PMSF confirmed that the wheat PEP is from the Serine protease family and is most likely a trypsin-like protease.

- Description: The research at hand focuses on job satisfaction as a moderator of the relationship between work-family conflict and stress among female civil service managers in the Department of Education in the King William’s Town District. Samples of 100 employees were used in the study. The data was collected by means of a questionnaire which consisted of the following sections: (i) a biographical and occupational data questionnaire,(ii) Eum, Lee, and Paek’s (2007) Effort-Reward Imbalance questionnaire, (iii) Bedenia, Burke, and Moffat’s (1998) Short-form Work-family Conflict questionnaire, and (iv) Halpern’s (1966) Job Satisfaction questionnaire. The data were analyzed by means of Pearson’s Correlation Technique, Multiple Regression Analysis, and Analysis of Variance. The results showed that job satisfaction does not moderate the relationship between work-family conflict and occupational stress. The study also found a significant positive correlation between work-family conflict and occupational stress and between work-family conflict and job satisfaction. It also showed that both work-family conflict and job satisfaction respectively accounted for a significant proportion of variance in occupational stress. The thesis ends with several recommendations for future research and for future professional or managerial practice.

- Description: This study is based on Leadership & Accountability in managing the Constituency Development Fund (CDF), the case of Yei River County (YRC) of Central Equatoria State, Republic of South Sudan (RSS). CDF is one of the initiatives of the government of South Sudan created by a legislation of Parliament to compliment development of the community needs as they expect more from the government of the day. The CDF Act 2007 which was passed by the parliament stipulated structures that govern the operation of the fund in terms of management, leadership and accountability to enhance effective and efficient provision of services to the people. The CDF Act provided that fund allocated to the MPs is to address the challenges that face the communities such as construction of schools, health facilities, water, roads and government facilities but not for personal interest or individual use. The problem that motivated the researcher to explore the performance of the CDF was inadequate service to the community although the government has allocated funds to each constituency channeled through the members of parliament to improve the socio-economic status of the community. The research looked at how the CDF roles, functions, and procedure were applied in the utilization of the funds to ensure efficiency. It analysed and evaluated the effectiveness and efficiency of management of CDF to promote service delivery in the constituencies of Yei, Ottogo, Tore and Mugwo Payams. The study investigated the following questions: How is the Constituency Development Fund (CDF) been managed and utilized by the Members of Parliament (MPs) to promote development in their constituencies? To what extent is the Constituency Development Fund (CDF) used in accordance with the provisions of the CDF Act (2007)? To what extent does the CDF achieve its objective in promoting development to meet the aspirations of the people within the constituencies? And, what is the nature of the relationship between the MPs, the community and the County Local Authority in relation to the CDF? The study also examined the linkage between the various committees formed by the CDF Act 2007 to guide the implementation of the fund as well as the projects at grass-root levels in regards to monitoring and evaluation process. The study used both descriptive and explanatory techniques to guide the researcher in gathering information required on the best of CDF practice in Yei River County which were carried out using interviews, focus group discussion and observation. Twenty (20) respondents comprising of head of departments, women, youth, MPs of both parliaments - the National and the State, chiefs, councilors, CDF committees from the four constituencies mentioned above were interviewed about the use of the CDF. The study reveals that there are no clear linkages between the various committees formed by the CDF Act 2007 to guide the implementation of the fund as well as the projects at the grass-root level in regards to monitoring and evaluation process. In addition to this, less participation of the community in identification, planning, implementation, monitoring and evaluation of the CDF community projects was one of the contributing factors that affected the effectiveness and efficiency of the result. Although creation of CDF has effect in some of the areas of the county, it requires more improvement in the implementation process to increase development in other areas. Based on these findings, the study argues that for the best of the CDF utilization, leadership and accountability which are components of the Public Administration Discipline that enhances efficiency in the public institutions need to be put into practice. Hence, rigorous application of the CDF rules, regulations and procedures is paramount in managing the utilization of the fund allocated for the purpose of development.

- Description: The purpose of this study was to explore and to describe experiences of learner nurses regarding clinical supervision at private hospitals in East London in the Eastern Cape. These were Life Healthcare hospitals. A qualitative, contextual approach was used and the exploratory, descriptive design was seen as most appropriate in this study. The subjects were the learner nurses in the Bridging Course Programme leading to registration as a General Nurse. The research questions were: How did you as a learner nurse, doing the Bridging Course, experience clinical supervision at Life Healthcare hospitals? A pilot study was conducted in a clinical setting involving respondents with similar characteristics to the study population. Fourteen participants were selected for this study by using a purposive, non-probability sampling method. Data were collected by means of individual interviews during which participants were able to describe their experiences during clinical supervision; data were collected until data saturation was reached.During data analysis, the researcher used the process of bracketing and remained neutral, setting aside previous knowledge and beliefs about the phenomenon under investigation.

- Description: The purpose of this study was to explore and to describe experiences of learner nurses regarding clinical supervision at private hospitals in East London in the Eastern Cape. These were Life Healthcare hospitals. A qualitative, contextual approach was used and the exploratory, descriptive design was seen as most appropriate in this study. The subjects were the learner nurses in the Bridging Course Programme leading to registration as a General Nurse. The research questions were: How did you as a learner nurse, doing the Bridging Course, experience clinical supervision at Life Healthcare hospitals? A pilot study was conducted in a clinical setting involving respondents with similar characteristics to the study population. Fourteen participants were selected for this study by using a purposive, non-probability sampling method. Data were collected by means of individual interviews during which participants were able to describe their experiences during clinical supervision; data were collected until data saturation was reached.During data analysis, the researcher used the process of bracketing and remained neutral, setting aside previous knowledge and beliefs about the phenomenon under investigation.

- Description: This study investigated the relationship between SAPS performance management and measurement assessment patterns and public perceptions of the effectiveness of SAPS. The Performance Management System (PMS) and the Performance Measurement System (PMS1) of SAPS were investigated and it was looked at whether there is a correlation between them. The two internal measurement systems i.e. PMS and PMS1 were compared with the perception of the community about service delivery effectiveness of SAPS. Seven police stations in the Queenstown Cluster participated in the study. Semi-structured interviews were used to gather data from the Cluster Commander, Station Commanders, Production personnel and members of the community. The findings indicated that SAPS has challenges in implementing PMS. Matters of honesty and trust were seen as contributing factors to these challenges. The internal performance management tools do not take into consideration the needs of the community. This transpired on the results of internal performance management which indicated police stations and their members to be performing satisfactory while the community is not satisfied with the police station performance.

- Description: This research study explored livelihood strategies that female headed households adopt in Magaso village of Mutoko district in Zimbabwe. The study intended to achieve the following objectives: (i) examine the existing livelihood strategies of female headed households (ii) explore the various challenges faced by female headed households and (iii) establish the support mechanisms in place for female headed households to cope with life challenges .The literature reviewed in the study was drawn from several researchers, and the study was shaped by the strengths perspectives and the liberal feminism perspective. The study was qualitative in nature and used interviews to collect data from fifteen (15) female headed households. The data collection process used an interview guide. The research employed a qualitative research design in the form of a case study cum a phenomenological study design. Data was analysed qualitatively using the content thematic data analysis which used interpretive approaches and presentation is textual rather than statistical. The study findings were the following: engaging in subsistence farming was found to be the main livelihood activity of the female heads; engaging in home gardens; exchanging labour for food; involvement in business; reliance on temporary employment from different agencies; reliance on handouts from government and other bodies; and household heads sanctioning child labour that compromises school attendance. Moreover, these female heads faced numerous difficulties ranging from emotional, social to financial problems that resulted in worsening the condition of women, and hence validating feminization of poverty among them. Several support mechanisms were discovered to be available for the female heads but they fail to produce to fruitful results to the lives of the female heads. The study made the following recommendations: mainstreaming gender education from childhood stage; efforts aimed at job creation; financial empowerment through setting up of micro schemes for rural women amongst; seeking the services of agricultural extension services to the female head farmers; improving the social services delivery in Zimbabwe equitably across genders and strengthening informal strategies to improve women‘s social capital. Lastly, the study concluded that little is being done in terms of policy formulation to make the support structures responsive to the female headed households especially in rural areas, hence the need for sustainable development through empowerment.

- Description: To proffer a sustainable solution to ecological degradation in rangeland ecosystems as a consequence of fire, grazing and browsing, an understanding of rangeland ecological processes is vital. Due to the complexity of ecological processes and their interrelationships, it is usually difficult or expensive to directly measure status of ecological processes. Therefore, biological and physical characteristics are often used to indicate the functionality of ecological processes and site integrity. Long-term effects of fire, grazing and browsing on characteristics of the vegetation and organic matter and their subsequent effects on selected rangelands ecosystem ecological processes was conducted at Honeydale section of the University of Fort Hare farm in the Eastern Cape Province of South Africa and Matopos Research Station in Zimbabwe. In this study, attributes of biotic community integrity (species richness, composition and diversity), soil stability (basal cover, standing dead grass biomass, tuft to tuft distance, tufts diameter, canopy distance and stem to stem distance), productivity and plant vigour (grass yield, total canopy volume, plant height, canopy height, canopy diameter, main stem diameter, sprouts diameter and number of sprouts) and hydrologic function and nutrient cycling (grass litter biomass, soil organic carbon and microbial biomass carbon) were used to estimate long-term effects of burning, grazing and browsing by goats on the functionality of ecological processes in the rangeland ecosystem. Burning did not have differential effect on grass species richness (P>0.05), woody species diversity as well as compositional percentage for D.eriatha, C.plurinodis, S.fimbriatus, A.karro and E.rigida. Burning increased decreasers and increaser II species proportions and reduced (P ≤ 0.05) grass yield, total canopy volume, tree height, canopy height main stem diameter and sprouts diameter. Long-term burning, grazing, and goats browsing had differential effects on site stability. The effects on basal cover, tuft to tuft distance, tufts diameter, canopy distance and basal distance as a consequence of long-term burning, grazing, and goats browsing were not significantly different, whereas the effects on standing dead grass biomass as a result of long-term burning frequencies were significantly different. Long-term effects of burning followed by ten-year period of fire exclusion had significantly different effects on tuft-tuft distance but did not have statistically different effects on tufts diameter, canopy distance and basal distance. Long-term burning grazing and browsing had significantly different effects on attributes of hydrologic functions and nutrient cycling in the rangeland ecosystem (grass litter biomass, SOC and BMC). Long-term effects of burning followed by ten-year period of fire exclusion had significantly different effects on grass litter biomass, and SOC. Through their effect on vegetation and organic matter characteristics, burning, grazing and browsing could influence functionality of selected rangeland ecological processes such as biological community integrity, productivity and plant vigour, site stability, hydrologic function and nutrient cycling.

- Description: The aim of the study was to investigate the management of HIV /AIDS programmes at the workplace in four selected organisations in Chris Hani District, Eastern Cape Province of South Africa. Four organisations were studied, two public organisations and two private organisations. With the use of triangulation method, two hundred employees were administered a semi- structured questionnaire while for (four) managers, semi structured in-depth interviews were conducted. The major findings of this study outline that all the four organisations studied have HIV/AIDS programmes and policies for their employees. However, there were no budget allocations for these programmes to be fully implemented for effectiveness. From the data, it can be concluded that HIV/AIDS has a negative impact on organisations‟ production like high training costs, high labour turnover and high absenteeism from work. This has been as a result of managers who did not put their total commitment towards HIV/AIDS management at their workplaces in the same way they have done to other core areas of businesses of their organisations. The study therefore recommends the management of these organisations to demonstrate a clear commitment to the HIV/AIDS management strategies by fully implementing the HIV/AIDS management programmes in their workplaces. It is very crucial for employees to see this commitment in a concrete form through non-discrimination and support for the people living with HIV/AIDS. Clear unambiguous commitment will go far in developing mutual trust between employers and employees and facilitate an atmosphere where people are willing to undergo VCT and to possibly disclose their status. Furthermore, managers are recommended to hire quality service providers to carry out intensive de-stigmatisation processes. This will create a supportive environment and adequately address the fears of employees about HIV/AIDS issues at the workplace. All these recommendations will go a long way in assisting organisations achieve their strategic business objectives and reduce the negative impact of HIV/AIDS at their workplaces.

- Description: Instances of fraudulent acts are often headline news in the popular press in South Africa. Increasingly, these press reports point to the government tender process as being the main enabler used by the perpetrators committing the fraud. The cause of the tender fraud problem is confidentiality breach of information. This is accomplished, in part, by compromising the tender information contained in the government information system. This results in the biased award of a tender. Typically, the information in the tender process should be used to make decisions about a tender’s specifications, solicitation, evaluation and adjudication. The sharing of said information to unauthorised persons can be used to manipulate and corrupt the process. This in turn corrupts the tender process by awarding a tender to an unworthy recipient. This research studies the generic steps in the tender process to understand how information is used to corrupt the tender process. It proposes that conflict of interest, together with a lack of information confidentiality in the information system, paves the way for possible tender fraud. Thereafter, a system of internal controls is examined within the South African government as well as in foreign countries to investigate measures taken to reduce the breach of confidential information in the tender process. By referring to the Common Criteria Security Model, various critical security areas within the tender process are identified. This measure is assisted with the ISO/IEC 27002 (2005) standard which has guiding principles for the management of confidential information. Thereafter, an information security policy,the Chinese Wall Model will be discussed as a means of reducing instances where conflict of interest may occur. Finally, an adapted Chinese Wall Model, which includes elements of the tender process, is presented as a way of reducing fraud in the government tender process. Finally, the research objective of this study is presented in the form of Critical Success Factors that aid in reducing the breach of confidential information in the tender process. As a consequence, tender fraud is reduced. These success factors have a direct and serious impact on the effectiveness of the Chinese Wall Model to secure the confidentiality of tender information. The proposed Critical Success Factors include: the Sanitisation Policy Document, an Electronic Document Management System, the Tender Evaluation Ethics Document, the Audit Trail Log and the Chinese Wall Model Prosecution Register.

- Description: The increasing population and the rapid economic growth in South Africa have led to higher consumption of food resulting in the generation of large amounts of waste. In addition, South Africa has plenty of biomass from cattle, donkeys, horses, goats, pigs, chicken and sheep. However, anaerobic digestion could be an alternative solution for the utilization of these kinds of waste due to its environmental and economic benefits. Therefore, the main focus of the research was design, construct a field batch biogas digester, monitor its performance when fed with co-substrates and model the methane yield for an optimized mixing ratio.

- Description: The Tuberculosis infection rate has been generally escalating due to poor health conditions in the Gweru district of Zimbabwe. The study therefore seeks to identify the risk factors that affect TB treatment in the Gweru district. A cross sectional study was carried out in which a questionnaire was employed for data collection on 113 respondents. A binary logistic regression model was employed for data analysis. A total of 98 TB patients were interviewed: [50 respondents (44.0%) had Multi-drug resistant Tuberculosis and 63 respondents (56.0%) had general Tuberculosis). Before being enrolled into the study, an informed consent form was given to each of the participants. The data was then put into excel and later transferred to SPSS for analysis. Out of the 14 potential risk factors of TB treatment, only 6 variables (side effects, gender, alcohol use, HIV status, smoking during the treatment period and having been pre-exposed to TB drugs) were statistically significant in their association with treatment failure.
