- Description: This study examined the impact of financial liberalisation on economic growth in South Africa. The study used quarterly time series data for the period 1980 to 2010. A vector error correction model was used to determine the short run and long run effects of financial liberalisation on economic growth in South Africa. The other explanatory variables considered in this study were government expenditure, investment ratio, public expenditure on education and trade openness. Results from this study revealed that financial liberalisation, government expenditure and public expenditure on education have a positive impact on economic growth while trade openness negatively affects economic growth in South Africa. Policy recommendations were made using these results.

- Description: Foreign Direct Investment (FDI) has been perceived by most developing countries, emerging economies and countries in transition as a major vehicle for development that would not only boost a host country’s economic development but also enhance its integration into the global economy. The common assumption is that presence of foreign companies in a host country, particularly a developing country, would lead to economic benefits; among them, transfer of technology, and skills and human capacity development. The establishment of special “development zones” and the roll-out of incentives to attract FDI are often predicated on the expectation by host countries that these benefits would be achieved. It is against this background that this study sought to find out the character of FDI in the East London Industrial Development Zone (ELIDZ), located in the Eastern Cape. The study focused on the institutional preconditions and incentives used by the ELIDZ to attract FDI into the zone, and on whether these had any bearing on labour and environmental standards as well as on local skills development. Empirical data for the study were collected using in-depth interview with senior management staff of both the ELIDZ as an organisation, and one of the foreign companies located in the zone (a “tenant” of ELIDZ). In addition, a mini survey was conducted with a random sample of employees of the selected ELIDZ company. Among the key findings of the study was that the ELIDZ had in place a range of incentives and preconditions for the attraction of FDI, and that there were concerted efforts on the part of ELIDZ management to compel companies operating in the zone to adhere to specific iv standards – especially on the environmental front. From the mini survey results, however, the study established that achievements on the labour front were mixed. While most of the responses indicated that ELIDZ was playing a positive role in terms of employment creation, a high number of responses (from surveyed employees in the selected ELIDZ company) pointed out that employment standards were in question. For example, 41% of respondents reported “unhappiness” with their conditions of employment, while 50% deplored the fact that they were not allowed to belong to unions. Furthermore, responses were nearly evenly split (53%/47%) between those who reported that their employment had resulted in the acquisition of new skills and those who reported that it had not. From these and other findings, the study concluded that ELIDZ was facing a “balancing act” by expecting foreign companies to create jobs, transfer technology and contribute to local skills development while at the same time adhering to strict environmental and labour standards. The study thus confirmed a major consensus in the FDI literature, while FDI could bring about important socio-economic achievements in a host country, foreign companies and host governments are not necessarily motivated by the same set of factors. Indeed, at least a small facet of the study’s findings seemed to confirm the well-documented anti-FDI sentiment that the faith placed in FDI by host governments (especially in developing countries) does not always have a sound basis.

- Description: The study investigates whether government-sponsored community development projects in the township of Mdantsane, Buffalo City Metropolitan Municipality, South Africa, have achieved the intended goal of alleviating poverty among the beneficiaries. The specific outcomes of poverty alleviation are: improved income, acquisition of new skills, reduced dependence on welfare grants. Four urban farming projects were selected, namely: Buffalo City Organic Producers, Sakhisizwe Nursery, Lusindiso Farmer’s Trading Co-operative and Mbombela Co-operative. Focus group discussions and a mini survey were conducted with project beneficiaries, while relevant government officials were interviewed. Conceptual insights were drawn from community development theory. The findings showed that the broader context within which the projects occurred was characterised by a pro-poor social policy, relative availability of resources with which to translate it into action, and a measure of entrepreneurial potential amongst community members. However, while one of the projects showed some promise (in the sense that beneficiaries acquired new skills and had a generally positive attitude despite not enjoying any improved income status), all the others appeared doomed and trapped in dynamics such as: excessive government control of the management of the initiatives, ineffective project monitoring, and the mischaracterisation of the initiatives by both the government and the beneficiaries. A distorted sense of ownership and perverse community participation seemed to prevail, which in turn robbed the initiatives of their poverty alleviation potential. The study thus concluded that specific benefactor-beneficiary dynamics are crucial for the success of a given anti-poverty intervention. A robust pro-poor social policy, availability of resources with which to translate it into action, and local entrepreneurial potential do not in themselves bring about success; they must operate in a certain way and be undergirded by certain principles for them to become a powerful mechanism for alleviating poverty. It is against this background that the researcher offers some recommendations.

Hiv/Aids communication and youth behaviour in South Africa: a study of female high school students in the Eastern Cape Province

- Description: Human Immuno-Deficiency Virus and Acquired Immune-Deficiency Syndrome communication remains one of the most significant tools in the fight against HIV/AIDS given the absence of the cure to fight the growth and spread of the global pandemic. Through the use of information, HIV/AIDS communication seeks to empower recipients or societies with skills that will help reduce their risk of infection. South Africa has seen a high visibility of HIV/AIDS communication programmes or campaigns aimed at empowering different audiences, whilst paying particular emphasis on the most vulnerable. Young people, in particular young women, have a higher prevalence of HIV/AIDS in South Africa. This has prompted the development of many youth focused communication campaigns which have sought to address factors that increase young people`s vulnerability to HIV infection. However, despite the high visibility of HIV/AIDS communication campaigns targeting young people, high risk behaviours are still being seen among young women. Important to note are the high teenage pregnancy rates, growing abuse of substances and even the premature engagement of sexual activities among female youths. This, therefore, raises questions on the effect of HIV/AIDS communication programmes in encouraging protective behaviour against risky behavioural practices amongst young women. Using both quantitative and qualitative research approaches to this study, an investigation was conducted into whether current HIV/AIDS communication campaigns have been limited (in terms of effectiveness) when it comes to communicating with young women on issues relating to HIV/AIDS. Awareness of HIV/AIDS and HIV/AIDS communication programmes, relevance of HIV/AIDS communication programmes, the factors that influence the use and understanding of HIV/AIDS messages and the impact of HIV/AIDS communication on attitude and behaviour change amongst female youths is measured. A total of 350 questionnaire copies were self-administered to 350 participants, with a 100 percent response rate. From the 350 participants, seventy five took part in focus group discussions. Data obtained was analysed using SPSS (for descriptive statistics), and the grounded theory. The results of the study indicate that all participants were aware of HIV/AIDS with at least 60% of the participants aware of at least three HIV/AIDS communication campaigns. When measuring the relevance of HIV/AIDS communication campaigns, participants (58%) indicate that issues discussed in most HIV/AIDS communication campaigns increased the relevance of HIV/AIDS messages to young women although such relevance was, for some respondents, affected by limited access to communication campaigns. Results also show that levels of knowledge and understanding of factors that expose young women to HIV infections differed amongst participants in as much as the factors that hinder the use of advice contained in HIV/AIDS messages also differed. Sixty-nine percent of the participants have knowledge and a better understanding of factors that expose young females to HIV infections. Twenty-five percent of the participants identified peer pressure, whilst 23% identified limited access to HIV/AIDS communication campaigns and another 18% identified a disregard of HIV/AIDS messages as significant factors that limit the ability of individuals to implement advice contained in HIV/AIDS messages. The results also indicate that although HIV/AIDS communication campaigns seem to have played a role in empowering some participants, there is still a significant minority whom communication has not effectively communicated with. Based on these findings, the study suggests, amongst other things, the need to intensify current HIV/AIDS communication campaigns through the provision of consistent messages on appropriate condom use, the identification of easily accessible communication channels and the development of thought provoking and attention grabbing campaigns as well as the need to continue to directly involve young women in the processes of their own development.

- Description: Most farming at subsistence level is located in rural areas where the majority of smallholder farmers have low productivity which results in high rate of food insecurity. The areas are characterised by animal traction and poor farming practises, and monoculture is mostly preferred. In light of this, this study analyzed the impact of animal power on agricultural productivity. Smallholder farmers in the lowlands of Mohale’s Hoek district of Lesotho were investigated by means of a case study methodology. The aim of the study was to inform agricultural policy about the level and key determinants of inefficiency in the smallholder farming system so as to contribute to policy designed to raise productivity of smallholder farmers. The sampling frame comprised farmers and extension workers in the lowlands of Mohale’s Hoek district. From this frame, 118 farmers and 4 extension workers were randomly selected from four villages, namely‘Mapotsane, Potsane, Tsoloane and Siloe. The four groups of farmers include; the farmers owning and using cattle for ploughing, farmers owning tractor and cattle and using them for ploughing, farmers owning tractor only and using it for ploughing, and farmers who owned neither cattle nor tractor and normally hire these when ploughing operations are to be done on the farm. The interviews of these farmers and extension workers were conducted by means of semi-structured questionnaire which consisted of both open and close ended questions. The study used the stochastic frontier production model for the production efficiencies and linear regression model for the impact of animal traction on agricultural productivity. Both procedures provided insights into the relative contributions of animal power and traditional systems to poverty alleviation and food security in the project areas. Descriptive statistics were employed for farming systems and challenges facing small scale farmers. Gross Margins analysis was conducted for the animal power and tractor power yield levels for maize crop to compare the two types of power. Some diagnostic tests to detect serial correlation and heteroskedasticity and t-tests were also performed. The significant variables include the area of sorghum ploughed, members of the household that assist with family labour, education, quantity of fertilizer applied, time taken by the farmers in farming, members who are formally employed, household size, area of land ploughed, old age, costs of tractor and animal, marital status, income, area of maize ploughed, area of sorghum ploughed, quantity of fertilizers applied, costs of seeds and fertilizers applied, maize and sorghum yield and amount sold and consumed. The study revealed that monoculture is mainly practised and many smallholder farmers used traditional technologies that fail to replace nutrients in the soil. Nonetheless family labour was not a problem. During the farming season, tractors were used as the main source of power for ploughing. Most farmers hired these for maize production as it is a staple food crop even where animal power is available. It was noted that the tractors were few and in most cases old and malfunctioning. The cost of using animals in farming obviouslyplayed a role in the production of both maize v and sorghum in the lowland areas of Mohale’s Hoek district. Smallholder farmers who owned both tractors and animals produced more but they were mainly affected by high costs of maintaining the aging tractors, generally purchased on the used-equipment market. The increased challenges resulted in lower productivity of the smallholder farmers, including: unhealthy animals, drought, marketing problems, late ploughing, poor soils, lack of extension services, low yields, low income, lack of information, lack of appropriate implements, lack of support services, nutrition inadequacy, inappropriate farming systems. The study recommended the adoption and promotion of low-cost mechanization in the lowlands of Mohale’s Hoek district so as to increase the production of the smallholder farmers. Increased productivity will in turn improve household food security.

- Description: The Internet has made a considerable impact on how business is conducted. Empowered by technology consumers are using the Internet as a tool to communicate and transact online. E-commerce (electronic commerce) presents opportunities for business to gain a competitive advantage, however it also posses certain challenges. Small and Medium Hospitality Enterprises (SMHEs) sector within the tourism industry, is one of the sectors which stands to benefit from using the Internet for business. Researchers agree that the contribution made by the tourism sector in developing economies is substantial. However, SMHEs are noted for their failure to derive optimal benefits from using the Internet for business to improve their competitiveness. This study which seeks to develop a model for use by SMHEs as a guide when making the decision to adopt technology was necessitated by the importance of SMHE’s contribution in the economy of developing countries. This model is based on the examination of existing theories and models such as; the Delone and McLean IS success model (2004), and the ITGI’s (2007) IT governance focus areas model. To elicit the desired outcomes, additional data was collected using questionnaires, interviews, and observations. The collected data was analysed and resulted in the development of a model that can be used by SMHEs in order to derive value from IT and to gain a competitive advantage.

- Description: The study focused on the exploration of the implication of partnership between the government and civil society organizations in the implementation of the Zimbabwe National Orphan Care Policy (ZNOCP). The study was carried out in Masvingo District in Zimbabwe to explore on the feasibility of inter-organizational interaction in policy implementation and how it affects the service delivery system. The study incorporated government departments, civil society organizations and ward councillors who stood as the custodians of the people. The study was intended on unveiling the different contextual aspects that exist between government departments and civil-society organizations (CSOs) as individual and separate entities and how the compromising of their values would affect the partnership. Looking at the hierarchical and bureaucratic features of government institutions, the study also intended to understand how this could be concealed and compromised with CSOs‟ open agendas in public policy implementation to ensure effective service delivery to the people. The 5C protocol, critical variables in policy implementation which are policy content, context, capacity, commitment of those entrusted with the implementation process and also clients and coalitions were used as the yardsticks. These variables acted as a yardstick on which to analyze the partnership between the Zimbabwean government and the civil society in the implementation of the Z.N.O.C.P, their different attitudes, bureaucratic settings, organizational culture, values, norms, and how their readjustments or failure affect the service delivery system. It also became imperative to look at the government legislations that govern the CSO space of operation and financial aspects to understand the implications of partnership between government and civil society. An understanding of these aspects leads to an increased understanding of the feasibility of state-CSO partnerships and its implications on policy implementation.

- Description: Smallholder agriculture is faced with so many challenges despite all the policies and programmes that have been channelled towards ensuring improvement in this sector. Improving smallholder agricultural productivity requires that smallholder farmers gain access to reliable and adequate farmer support services such as physical infrastructures like good road network, functional irrigation facilities, extension services, finance and efficient marketing system. However, these support services are lacking in a vast majority of the rural communities in which the smallholder farmers live and work. This study is centred on governance within the food value chains, with specific focus on butternuts and chicken value chains;with a view to identifying those factors preventing smallholder farmers from accessing the mainstream market. Ciko and Mbozi villages in Mbashe local municipality were used as the research sites for the study. Data were collected across the two villages through sampling of 100 individual farming households based on random selection; questionnaires and checklist of questions were used as tools to access information from farmers through focus group discussions, personal interviews and key informants. In addition,Ciko Santrini project and foundation community project, which are the two agricultural community projects located within the study area were also investigated.

The results showed that factors such as; assistance from government agency, partnerships with private and public institutions and farmers’ decision due to access to information were significant at 1% level for both butternuts and chicken production. On the other hand, factors such as provision of input subsidy and farmers’ membership of agricultural development projects are significant at 5% level. The findings suggest that adoption of any or combination of the significant factors could serve as good support structures for farmers and they could directly help them market their produce efficiently.

- Description: The control of inflation requires a forecast of the future path of the price level and its indicators. Targeting inflation directly requires that the central bank (SARB) form forecasts of the likely path of prices paying close attention to a variety of indicators that shows the predictive power of inflation in the past periods. Inflation indicators might be cointegrated with the rate of inflation to predict the future inflation rates. Forecasting inflation may be very difficult at a particular period due to the fact that the array candidate indicators of inflation may neither be very stable nor very strong in their relationships with the rate of inflation. Although this might be the case, this research uses testable effects of each of the South African inflation indicators to the rate of inflation using econometrics tools to find that they have a long run trend with the rate of inflation in South Africa. It has been found that each of the indicator variables has a long run relationship with the rate of inflation. The major conclusion is that inflation indicator variables like money supply (M3), oil price, gold price, total employment, interest rates, exchange rates and output growth can be useful inflation indicators in targeting the future trends of inflation in South Africa according to the data used in this research although some studies in some countries find that inflation targeting is an insufficient framework for monetary policy in the presence of financial exuberance. The money supply, the oil prices, interest rates, the exchange rates, prices of gold, the employment and output growth are co-integrated with the rate of inflation representing a long-run relationship.

- Description: Urease of Helicobacter pylori is an important virulence factor implicated in the pathogenesis of many clinical conditions, such as chronic gastritis, peptic ulceration, and gastric cancer. Many urease inhibitors have been discovered, like phosphorodiamidates, hydroxamic acid derivatives, and imidazoles. Despite good activities at the enzyme level and excellent kinetic properties most of them have not been used as therapeutic agents in vivo because of their side effects, toxicity and instability. This has led to much attention to focus on exploring the novel urease inhibitory activities of natural products because of their low toxicity and good bioavailability. Honey, a natural product has been used in folk medicine due to its antitumor, antioxidant, antimicrobial and anti-inflammatory properties. The aims of this study were to isolate, characterise, purify urease produced by H. pylori and investigate the inhibitory effects of solvent honey extracts on its enzymatic activity. Urease was found to be both surface-associated and cytoplasmic. Maximum cytoplasmic urease activity was found to occur after 72 hr whereas maximum extracellular urease activities were found to occur after 96 hr. Characterization of the crude cytoplasmic urease revealed optimal activity at a pH of 7.5 and temperature of 40°C. The kinetic parameters Vmax and Km were 45.32 U ml-1 and 61.11 mM respectively.The honey extracts inhibited the activity of the crude urease in a concentration dependent manner. The Lineweaver-Burk plots indicated a non-competitive type of inhibition against H. pylori urease. The two honey extracts gave promising inhibitory activities against urease of H. pylori. Thus the results of this study delineates that inhibition of urease can ease development in therapeutic and preventative approaches based on the enzymatic activity of this Helicobacter protein.

- Description: SFME and HD for the extraction of essential oil in Lavandula officinalis in Alice have been reported. A total of 59 compounds were identified with the major compound being 1,8-cineole, an oxygenated monoterpene, with 46.89% and 44.84% yield obtained for HD and SFME respectively. Charge transfer (CT) complexes formed between α-pinene, 1,8-cineole and camphor as electron donors with iodine as the electron acceptor have been studied spectrophotometrically in methylene chloride solution. The Benesi- Hildebrand equation has been applied to estimate the formation constant (Kf) and molecular extinction coefficient (εCT). The value of Kf is the highest in camphor-I2 complex compared to the other two complexes. Antibacterial assessment was carried out on the various reagents, determining the MIC of individual reagents and in combination. The results show an improvement, on combination of the various reagents than when tested alone.

- Description: Knowledge is now regarded as the most important resource surpassing other resources like land and capital. It is a foregone conclusion that knowledge flows out of organizations through various ways such as resignations, retirement and death yet, it does not seem as if organizations are employing strategies to retain such a vital component of production and service delivery. This study investigated the knowledge retention strategies in three Southern Africa Development Community (SADC) public broadcasting organizations of the South African Broadcasting Corporation in South African (SABC), the Department of Broadcasting Services (DBS) in Botswana and the Zimbabwe Broadcasting Corporation (ZBC) in Zimbabwe. The aim of this study was to establish how knowledge is captured and retained at such organizations. The objectives of the study were; to find out the types of strategies the three broadcasting organizations employ to capture and retain knowledge; establish how the three broadcasting organizational cultures enable knowledge acquisition, transfer, sharing and retention; establish the role of ICTs as tools and enablers of knowledge retention, creation, transfer and sharing in the three broadcasting organizations; and to propose recommendations on the best strategies for retention of knowledge in the three public broadcasting organizations as well as suggest areas for further and future research. v The study used the survey method and employed the triangulation design for data gathering. Data were collected from three SADC public broadcasting organizations. The population sample comprised 240 professional staff including 38 managers from different sections of the broadcasting organizations. The researcher collected data by administering a questionnaire to staff, interviews with managers and observations. Documentary analysis was also conducted in order to supplement data and fill in gaps. The researcher was mainly interested in gathering data that would give a comprehensive picture about knowledge retention methods in broadcasting organizations. There were four main findings. First, knowledge management as a relatively new concept and practice has not yet been properly embraced in the public broadcasting organization system in order to capture and retain knowledge that is acquired and generated in the organizations. There are no measures put in place in the organizations to retain the knowledge to ensure that once those who hold vital tacit knowledge are gone, the knowledge may still be available and accessible. Second, the study established that the respective organizational cultures impede on organizational knowledge retention. The study established that there was no culture of knowledge sharing. It also emerged that employees were not free to share their knowledge because of government regulations, prevailing political contexts, mistrust and general lack of incentive to share knowledge. Third, the study established that the organizations have no strategies or systems in place to capture the experts‟ knowledge or the knowledge of experienced staff and vi those approaching retiring age. The Human Resources Departments hold exit interviews that cover issues purely to do with why the person is leaving the organization instead of recording the work experiences and expertise of the departing employees. Fourth, the study revealed that the public broadcasting organizations still lag behind in collaborative and communicative technologies that facilitate knowledge transfer and sharing of tacit knowledge but retention of knowledge generally. The study also found that, some of the organizations studied did not have internet connectivity and websites were not yet functional, which hampered acquisition and sharing of knowledge for retention purposes. The importance of this study is that it has made a contribution and provided literature on knowledge retention strategies for public broadcasting corporations as part of knowledge management practice. On the basis of these findings the study recommended the following: appointment of knowledge management officers, establishment of Communities of Practice, encouraging knowledge sharing between employees, introduction of joint programmes with other broadcasting organizations by managers and their supervision of mentoring programmes; organizations to facilitate acquisition of information and communication technologies that enable knowledge management

Legal status and protection of animals in South Africa

- Description: The animal welfare legislation that is discussed in this Dissertation is just a sample of the available legislation from the chosen foreign jurisdictions and South Africa. The chosen foreign jurisdictions were chosen as a lens to gain a needed perspective on South African animal welfare legislation. The legislation chosen for discussion falls within particular categories that are discussed fully in the later chapters.i Despite the fact that the animal rights and animal welfare movements are recorded to date back as far as 500B.C, the majority of jurisdictions throughout the world still consider animals to be property that can be bought, traded, hunted and after they are killed, their remains kept as trophies or souvenirs. Within these jurisdictions (which includes South Africa and the other four chosen foreign jurisdictions – Kenya, India, Switzerland and the United States of America) there is a demonstrated lack of proper enforcement of the animal welfare/animal anti-cruelty legislation, regulations and industry rules, which is made worse by the actions of uncaring, abusive and/or ignorant people. South Africa is no better or worse to the four chosen jurisdictions in that it has similar anti-cruelty/animal welfare legislation. The lack of proper enforcement of this animal welfare legislation in South Africa should be of great concern as many studies have indicated that there is a link between animal abuse/cruelty and ‘human’ abuse. The same studies also indicate that animal abusers are at a greater risk of becoming violent criminals or of committing a violent crime. For example, the Federal Bureau of Investigation has noted that most serial killers in the USA had a history of torturing, abusing and killing animals before they moved on to torturing, abusing and/or killing humans in their adult life. Needed changes to the animal welfare legislation and how people view animals should be made in South Africa to ensure that welfare of animals is protected. For example, the Government could educate people about animal welfare in order to overcome any ignorance that may be the cause of animal pain and abuse, as well as strengthening existing animal welfare legislation. The eradication of ignorance, as well as a necessary change in the current animal welfare legislation, will help to create a real change in how people view and treat i Chapter 5 and 6. [iii] animals. People will come to realise that animals exist in their own right and that they were not created to serve or to be exploited by man.

- Description: The animal welfare legislation that is discussed in this Dissertation is just a sample of the available legislation from the chosen foreign jurisdictions and South Africa. The chosen foreign jurisdictions were chosen as a lens to gain a needed perspective on South African animal welfare legislation. The legislation chosen for discussion falls within particular categories that are discussed fully in the later chapters.i Despite the fact that the animal rights and animal welfare movements are recorded to date back as far as 500B.C, the majority of jurisdictions throughout the world still consider animals to be property that can be bought, traded, hunted and after they are killed, their remains kept as trophies or souvenirs. Within these jurisdictions (which includes South Africa and the other four chosen foreign jurisdictions – Kenya, India, Switzerland and the United States of America) there is a demonstrated lack of proper enforcement of the animal welfare/animal anti-cruelty legislation, regulations and industry rules, which is made worse by the actions of uncaring, abusive and/or ignorant people. South Africa is no better or worse to the four chosen jurisdictions in that it has similar anti-cruelty/animal welfare legislation. The lack of proper enforcement of this animal welfare legislation in South Africa should be of great concern as many studies have indicated that there is a link between animal abuse/cruelty and ‘human’ abuse. The same studies also indicate that animal abusers are at a greater risk of becoming violent criminals or of committing a violent crime. For example, the Federal Bureau of Investigation has noted that most serial killers in the USA had a history of torturing, abusing and killing animals before they moved on to torturing, abusing and/or killing humans in their adult life. Needed changes to the animal welfare legislation and how people view animals should be made in South Africa to ensure that welfare of animals is protected. For example, the Government could educate people about animal welfare in order to overcome any ignorance that may be the cause of animal pain and abuse, as well as strengthening existing animal welfare legislation. The eradication of ignorance, as well as a necessary change in the current animal welfare legislation, will help to create a real change in how people view and treat i Chapter 5 and 6. [iii] animals. People will come to realise that animals exist in their own right and that they were not created to serve or to be exploited by man.

- Description: The Kalagadi Manganese mine in the Kuruman area of the Northern Cape Province of South Africa contains reserves of Mn ore in excess of 100Mt. Mineralization in the mine lease area is restricted within the Hotazel Formation of the Voȅlwater Subgroup, belonging to the Postmasburg Group, the upper subdivision of the Transvaal Supergroup. Surface topography is characterized by flat lying, undulation with minimal faulting and the ore are slightly metarmophosed. This study investigates the general geology of the mine, lithostratigraphic subdivision and correlation of the economic Lower Manganese Orebody (LMO) of the Kalagadi Manganese Mine in order to guide mining plan and operations once the mine is fully commissioned. At the commencement of this study, Kalagadi Manganese mine was a project under exploration with no specific geology of the mine lease area and no lithostratigraphic subdivision. The study also aimed determining the extent of lithostratigraphic correlation between the LMO economic orebodies of the Kalagadi Manganese mine with that of underground Gloria and open-pit Mamatwan mines. Four methods including petrographic microscope, Scanning electron Microscope (SEM), X-ray diffraction (XRD) and X-ray fluorescence (XRF) analyses were applied mainly for the mineral identification, chemical composition and ore characterization of the Lower Manganese Orebody (LMO) at Kalagadi Manganese mine. The results of this study indicates the following: (1) Eleven textural distinct zones with economic zones restricted to the middle while the lower grade zones are confined to the top and bottom of the LMO; (2) The economic zones, comprising of Y, M, C and N subzones attain an average thickness of 10 m and are graded at an average of 40% Mn while the Mn/Fe ratio varies from 6 to 9; (3) The most economic zones are M and N subzones which are mostly characterized by oxidized ovoids and laminae, a characteristic applicable even to other zones of economic interest; (4) Braunite is the main mineral of the manganese ore and is often integrown with kutnahorite and other minerals (hematite, hausmannite, Mg-calcite, calcite, jacobsite, serpentine and garnet) which are present in variable amounts; (5) The Mg-rich calcite (Ca, Mg)CO3 is the second dominant manganese carbonate mineral and it corresponds to elevated MgO concentration and is often associated with marine environment. The occurrence of the Mgcalcite is not common in the manganese ore of this area except for the Mn-calcite, which was not determined by XRD analyses in this study; (6) MnO is the most abundant major oxide in the manganese ore while other major oxides present in decreasing order of abundance are CaO, SiO2, Fe2O3, and MgO. The oxides TiO2, Na2O, K2O, Al2O3, and Cr2O3 are depleted and are mostly 0.01wt% and 0.001wt% respectively while P2O5 concentrations are low ranging from 0.02wt% to 0.3wt%. The trace element concentrations of Ba, Zn and Sr in most borehole samples are slightly elevated ranging from 100ppm to 3.9% (36000pm) while Co, Cu, Ni, Y, As, Zr, V and La rarely exceed 50ppm. The enrichments of Cu, Zn, Ni, Co and V that are commonly associated with volcanogenic hydrothermal input in chemicals may reach up to 70ppm; (7) The mineralogical and geochemical characteristics of the manganese ore in the Kalagadi Manganese mine lease area are similar to that of Low-Grade Mamatwan-Type ore. The cyclicity (Banded Iron Formation ↔ Hematite lutite ↔ braunite lutite) and alternation of manganese and iron formation have been confirmed; and (8) The oxygen δ18O isotope values (18‰ to 22‰) indicate a slight influence of metamorphism of the manganese ore. No positive correlation exists between δ13C vs δ18O values and Mn vs δ13C values. Such observations indicate minimal action of organic carbon during manganese precipitation where the organic matter was oxidized and manganese content reduced. On the other hand, the manganese carbonates (CaO) are positively correlated with carbon isotope, this indicates diagenetic alteration and the involvement of biogenic carbonate during the formation of manganese carbonates. It is concluded that the lithostratigraphic subdivision at Kalagadi Manganese mine is best correlated physically, mineralogically and geochemically with that of Gloria mine operating in the Low Grade Mamatwan - Type ore while correlation with an open-pit Mamatwan mine is also valid.

- Description: This study examines the lifestyle decisions of people who are diagnosed with HIV/AIDS in King Williams Town, Eastern Cape. The study was motivated by the ever growing number of people who are now living with HIV/AIDS. Therefore the researcher intended to examine their decisions regarding sexual choices, reproductive health, diet, physical fitness and their coping strategies. The study found that there is very low uptake of Voluntary Counseling and Testing (VCT). Most people only get tested if they are compelled by other factors, like illness and pregnancy. It also found that HIV positive people continue to engage in risky sexual behaviour regardless of their positive status. In addition it also found that HIV positive status does not affect sexual activity and social support from family and friends is a very important factor that is helping the respondents to cope with HIV diagnosis.

- Description: South Africa is burdened with tuberculosis (TB) which is aggravated by the concurrent epidemic of HIV as well as the emergence of drug resistance. In most developed countries molecular techniques have been used to look at the dynamics of the TB epidemic however, despite the prevalence that is high in sub-Saharan Africa, there is little data on strain types that are available in Port Elizabeth. This study aims to find the major clades of M. tuberculosis that are circulating in Port Elizabeth. Two hundred MDR-TB DNA samples were obtained from the National Health Laboratory Services TB laboratory in Port Elizabeth. Spoligotyping and MIRU-VNTR were used to genotype the strains. Two hundred strains were sent to the University of Stellenbosch for spoligotyping and 179 of those were typed. Spoligotype defined families were further typed by MIRU-VNTR typing, so as to further differentiate and assess clonal diversity within the spoligotype families. The Beijing family was the dominant family and the MANU family being the least dominant, with percentages of 71 percent and 0.5 percent respectively. A comparison of spoligotyping results with the international spoligotyping database (SITVIT2) showed a total of 15 shared international types. Forty four percent (44 percent) of the isolates that were typed by MIRU-VNTR showed similarities, suggesting epidemiological relatedness. Thirty eight percent of isolates from spoligotyping were from the same family, the Beijing family, with the same shared international type STI1, but when typed by 12 MIRU-VNTR they showed no epidemiological relatedness and 18 percent of the isolates showed no relatedness when typed by 12 MIRU-VNTR but spoligotyping showed that they were from the LAM family. Results from our study illustrate the effectiveness of MIRU-VNTR typing together with spoligotyping in epidemiological studies in the region of Port Elizabeth.

- Description: The government of South Africa has seen many financial reforms in the finance industry since the attainment of freedom in 1994. Many microfinance institutions (MFIs) have emerged in the name of poverty reduction, however the impact of MFIs on poverty reduction in rural areas has not been significantly high. Poverty has been reduced but still the inequality gap has even widened (HSRC, 2004). The study is concerned with analysing the impact of MFIs in poverty reduction among the rural poor. Empirical evidence from many developing nations around the world has shown that microfinance is a tool that is relevant in reducing poverty within rural areas. This study investigates the impact of microfinance institutions on household income levels, education and business skills. The study followed a qualitative approach in terms of the research methodology and a survey research design. Data was collected using questionnaires, scheduled interviews, focus group discussions and key informants. Two sample techniques were used for the selection of the MFIs and the household respondents, that is purposive sampling and cluster sampling. In total, 150 households, 15 MFIs and five key informants were interviewed. Descriptive analysis methods were employed and the study showed that only 10 percent of the total households have been able to access microfinance. The number of people who gained business skills was also low (10 percent). The MFIs who provide financial services excluding the other services like business training programmes were 80 percent of the total number of MFIs interviewed. This data showed that only a few (20 percent) MFIs are willing to go an extra mile rendering business skills to their clients. Overally the major finding of the study was that although, MFIs are reaching out to the rural communities, their levels of outreach is still very low within the rural areas. However this does not mean that the impact of MFIs funding is not felt among the rural poor. The levels of income and educational benefits have been increased and felt by the 10 percent of the rural poor clients. This study advocates for an entrepreneurship development pathway to poverty reduction. Microfinance should be used as a source of finance to initiate entrepreneurial activities among the poor in order to generate income. In this study, the use of microfinance finance for consumption by the poor is discouraged because it depletes the funds that can be channeled for selfhelp projects within the rural communities. The study findings motivated the recommendations that encourage an inclusive financial system that is capable of reaching out to the rural poor.

- Description: In order to achieve sustainable agriculture, decision makers require appropriate and fully detailed spatial information on land resources. Crop-land suitability analysis is a prerequisite to achieve optimum utilization of the available land resources for sustainable agriculture rural production (T.R. Nisar Ahamed et al., 2000). It is indeed of paramount importance to identify suitable land for cropping while causing minimum impact to the environment. The Food and Agriculture Organization (FAO, 1976), recommended an approach of land suitability evaluation for crops in terms of suitable land based on climatic and terrain data and soil properties. In this study, an attempt was made to identify suitable areas for massive crop production using remote sensing and GIS methodologies and the knowledge from extension officers. The primary method aims at generating land cover data using SPOT 5 satellite imagery and modeling with the existing land capability. The research purpose was to map the map the number hectares suitable areas for crop production number hectares suitable areas for crop production number hectares suitable areas for crop production number hectares suitable areas for crop production. Spatial modeling techniques were utilized to model land suitability model in an effective and efficiently way. The spatial modeling extension from ESRI product was used to model the crop suitability areas. The model run on ArcGIS platform and due to the fact that modeling only uses raster formats, all the data sets were projected and converted to raster format. The weighted overlay model was used to create land suitability map. The model results revealed that 4046251.79 hectares were suitable for cropping in the study area. The final outputs of suitable areas were calculated and each ward was given a value of suitable area as well as unsuitable area. The validation of the final maps compliments the 500 000 hectares that were mapped by Dept of Agriculture EC using 8% slope as the best potential areas. The method provides a cheap, effective and efficient way to map suitable areas over a large area and it also uses remote sensing data. It is hoped that decision makers will make use of the information produced in this paper as the whole world is in crisis of food security.

- Description: Mycobacterium tuberculosis complex (MTBC) organisms are the causative agents of tuberculosis in humans as well as animals. The study aimed to use molecular techniques for detection and drug susceptibility testing of MTBC in raw milk from cattle at a dairy farm in the Nkonkobe region of South Africa. Two hundred samples (100mL each) were collected and processed using the modified Petroff’s method. DNA was isolated using the Zymo Research bacterial DNA kit and amplified using the Seeplex® MTB Nested ACE assay. Drug susceptibility testing was performed using the Genotype® MTBDRplus assay. MTBC DNA was detected in 11 (6percent) of the samples tested. Resistance to both rifampicin and isoniazid was detected in 90.9percent of the positive samples. The most frequent rpoB mutations detected were H526Y (90percent), H526D (80percent), S531L (60percent) and D516V (20percent). No mutation was detected in the katG gene. All isoniazid resistant samples harboured mutations in the inhA gene. The most frequent (100percent) mutation conferring low level isoniazid resistance was the T8A substitution. The inhA mutations C15T, A16G and T8C were equally represented with 60percent frequency. A high prevalence of multi-drug resistance was noted in the Nkonkobe region. Therefore, the results of this study have clinico-veterinary and epidemiological significance and calls for further studies and necessary actions to delineate the situation. , Thesis (MSc) -- Faculty of Science and Agriculture, 2012

The study aimed to use molecular techniques for detection and drug susceptibility testing of MTBC in raw milk from cattle at a dairy farm in the Nkonkobe region of South Africa. Two hundred samples (100mL each) were collected and processed using the modified Petroff’s method. DNA was isolated using the Zymo Research bacterial DNA kit and amplified using the Seeplex® MTB Nested ACE assay. Drug susceptibility testing was performed using the Genotype® MTBDRplus assay. MTBC DNA was detected in 11 (6percent) of the samples tested. Resistance to both rifampicin and isoniazid was detected in 90.9percent of the positive samples. The most frequent rpoB mutations detected were H526Y (90percent), H526D (80percent), S531L (60percent) and D516V (20percent). No mutation was detected in the katG gene. All isoniazid resistant samples harboured mutations in the inhA gene. The most frequent (100percent) mutation conferring low level isoniazid resistance was the T8A substitution. The inhA mutations C15T, A16G and T8C were equally represented with 60percent frequency. A high prevalence of multi-drug resistance was noted in the Nkonkobe region. Therefore, the results of this study have clinico-veterinary and epidemiological significance and calls for further studies and necessary actions to delineate the situation. , Thesis (MSc) -- Faculty of Science and Agriculture, 2012

- Description: A central concern of education internationally and in South Africa is to develop children's literacy skill. However a literacy crisis exists in spite of efforts to counter this. Some researchers have explored the issue of literacy focusing on second language learners‟ spelling in English as Additional Language. There is, however, insufficient literature that looks into spelling experiences of isiXhosa background learners in English First Additional Language. Hence this study investigated the nature of spelling errors of Grade three isiXhosa background learners in English First Additional Language. In understanding the nature of spelling errors of Grade three isiXhosa background learners, the features of words that learners find difficult to spell and the features of words that learners find easy to spell were investigated. Moreover, learners' barriers in acquiring spelling skills in English First Additional Language and teacher practices for teaching spelling were examined. In exploring these issues the study adopted a qualitative approach in order to ensure reliability and validity of the study. The data gathering process was in the form of semi-structured interviews, classroom observations and document analysis. One isiXhosa medium primary school in a Black Township in Buffalo City Municipality in the East London District was purposively selected to form the context of the study. In this school English is taught as a subject in grade three. Participants were eight grade three learners and one Grade three class teacher who teaches these learners. The findings of the study revealed that learners with an isiXhosa background seemed to be struggling with understanding basic English words and terms. This is exacerbated by the fact that the learners seemed to struggle to understand the rules of the English language. The words that learners find difficulties in to spell in English Second Language were diagraphs. Barriers to spelling were influenced, among other issues, by learners' pronunciation and their heavy reliance on their mother tongue.
