- Description: Lesotho has a land area of about 30.340 square kilometers and is completely surrounded by the Republic of South Africa. Much of the country is mountainous. Its agricultural sector is characterized by low productivity due to erratic climatic conditions, limited arable land and fragile soils with a low water holding capacity. These conditions have proved very detrimental to crop production, rendering agriculture a risky economic activity. Numerous efforts have been made over the years to address the technical constraints confronting the sector, but nothing seems to be changing. The implication is that the technical/climatic factors mentioned above may be only part of the problem. The current situation whereby Lesotho imports nearly 95% of its domestic food requirements is unsustainable, but this desperate picture looks set to worsen with the continuing threats of contracting farm sizes and further declines in farmer participation rates. But this sector has continued to be an important source of household survival and existence. A study was designed and conducted during 2008 and 2009 to identify the institutional constraints to horticulture production in Lesotho, looking specifically at the obstacles to effective production and marketing of horticultural products. A total of 100 farming households were enumerated in four districts of the country, namely Butha Buthe, Berea, Mafeteng, and Thaba-Tseka. A range of institutional and non-price factors in the farming and marketing environment were incorporated in a binary choice model to investigate the degree of satisfaction of the farming households with their previous year’s farming results. To avoid selection bias in the sample, a probit model was chosen, and the Stata-10 software was used to estimate probit coefficients. The results provide indications that property rights, the agricultural extension service, the condition of the physical infrastructure, and distance to markets may be crucial elements threatening the existence of this sector in Lesotho. The difficulties in accessing markets and land remain important institutional constraints to horticulture production and marketing in Lesotho. Recommendations made on these issues include providing more policy support to homestead gardening and for these issues to be incorporated into the Vision 2020 process. Also to be included is the issue of addressing the growing national food insecurity and enhancing Basotho livelihoods in general.

- Description: For decades, there has been significant investment in the development of agricultural technologies that aim to increase productivity of smallholder farmers in Africa. But farm output and productivity have stagnated and poverty rates have remained high and even increasing in some areas. At the same time, increases in human population levels have resulted in rising demand for food as well as for arable land. The growing intensification of farming has been accompanied by degradation of wild lands, including tropical forests and wetlands, at an alarming rate. Further pressure on fragile land has come from associated urbanization, leading to agricultural land being converted to residential and industrial uses with serious consequences for agricultural production and food supply. The recent increases in food prices across the globe as well as South Africa have drawn attention to this problem even more strongly. The main objective of the current study was to investigate farmer’s perception of the relative importance of crop-livestock integration in the small holder farming systems. Data were collected from 70 emerging and smallholder farmers selected by stratified random sampling in the communities surrounding Alice, Middledrift and the Seymour- Balfour area of Nkonkobe municipality of the Eastern Cape Province. To collect the data, a semi-structure questionnaire was administered to the respondents through face-to-face interviews. Descriptive statistics were used to characterize the farmers in terms of their socio-economic and demographic backgrounds. A series of multiple linear regression models and a binary logistic regression equation were fitted to determine the factors influencing farmers’ perception and how these in turn contribute to the decision to adopt or not to adopt crop-livestock integration. The results of the study reveal that small farmers in the Nkonkobe municipality have the possibility of realizing immense benefits from the integrated systems which also have the potential to lead to substantial improvements of the physical, chemical and biological soil properties. There is clear evidence of widespread interest to experiment with the practices based on the strong positive perceptions that a majority of the survey farmers exhibited during the course of the survey. But the farmers are facing challenges in coping with the associated complexities of competition on land, and management skill which are often in limited supply. That in most cases is not enough and efficient even to manage one of these two enterprises alone and reduction in crops yield due to use of manure as a substitute of fertilizer. Constraints to integrating crops and livestock include the competition for resources, especially land. Managing two types of farming on the same farm was perceived as difficult and many respondents held the view that use of waste of one enterprise as input to the other enterprise can reduce productivity. For example some farmers considered that the use of manure to improve soil fertility may not lead to output growth to the same extent as the use of fertilizer. A number of farmers (86%) pointed out that they only market their produce after deducting their consumption share, highlighting the crucial role of food security as a motivation for crop-livestock integration. Complementation of inputs rather than substituting inputs is required to render the system more productive and sustainable as costs are minimized and output is boosted. Associations of grain and livestock producers are useful for filling these gaps which include limited access to credit, technology and knowledge and can promote the adoption of a crop-livestock system.

- Description: The objective of this research report was to determine which internal controls are perceived, by internal auditors, to be contributing to the effectiveness of an internal control structure. The Committee for Sponsoring Organisations (COSO) integrated internal control framework was used as a basis for the questionnaire construction and respondents were asked to rate the perceived control effectiveness of each of the components of internal control. Descriptive statistics were used to analyse the basic meaning of the data. The questionnaire was completed by following a Uniform Resource Locator (URL) which was sent to two internal auditors in audit firms. Thirty one responses were obtained; all the respondents have experience in the evaluation and assessment of internal control systems. This research showed that control elements as outlined in COSOs integrated internal control framework, if implemented, could contribute to the effectiveness of the internal control system.

- Description: Paul Emmanuel is a South African artist who produces incised drawings, outdoor installations and prints (particularly intaglio etchings and manière noire lithographs). These focus on the representation of male bodies and experience. Having begun his career as a collaborative printmaker, since 2002, his work has become more ambitious as well as critically acclaimed. In 2010, his most recent body of work, Transitions, was exhibited at the Smithsonian Museum of African Art in Washington D.C. I propose that Emmanuel represents the male body as a presence that either is not easily seen or that actively disappears or erases itself. Its subjectivity, and the viewer’s engagement with it, may be characterised as one of intimacy, exposure, loss and vulnerability. Emmanuel’s work may be said to question conventions and ideals of masculinity while, at the same time, refusing any prescriptive interpretation. To develop this proposition, I examine specifically Emmanuel’s incising drawing technique that ‘holds open’ transitions in male lives. In these liminal moments, Emmanuel represents men as ‘seen’ to change state or status, thereby exposing the ongoing process of building masculine identities. Equally elucidatory is Emmanuel’s imprinting of his own body, which, in his use of “traces” that reveal the vacillation between presence and absence, makes contingently ‘visible’ this gendering process, and has particular implications for the expression of subjectivity in a contemporary South African context.

- Description: This thesis explores the origins, purposes, journalistic practices and outcomes of two award-winning projects namely Broken Homes and Slumlords done by Daily Dispatch's Gcina Ntsaluba in 2009. The projects were described by the paper as investigative journalism but interestingly the original idea came from grassroots driven strategies and they were done by adopting alternative news gathering strategies and immersion in the ordinary people, inspired by public journalism. This thesis follows Christians et al's (2009) normative theoretical framework of press roles summarised as the monitorial, facilitative, collaborative and radical roles. It provides normative prescriptions of public and investigative journalism, development and radical journalism. It then draws on sociological theoretical critiques in order to provide an analytical overview of the complex matrix of political, economic and media contexts which influenced the origins, purposes, journalistic practices and outcomes of the two projects. Drawing on a critical realist case study design, the thesis goes on to provide a narrative account of the two projects based on the in-depth interviews exploring the editorial staffs ideas on the origins, purposes, journalistic practices and outcomes of the projects and a qualitative content/thematic analysis of the journalistic texts related to the projects. This primary data is then critically evaluated against normative theories of press performance, especially Nip's (2008) key practices and Haas's (2007) 'public philosophy' of public journalism. It is also evaluated against a normative framework of what constitutes "good investigative journalism" based on Ettema and Glasser (1998), Waisbord (2000) among others. Protess et al 1991's classic mobilisation model is used to interrogate the projects' outcomes. The thesis established that there was a close connection of the monitorial (investigative journalism), facilitative (public journalism) and radical (tabloid journalism) roles at the paper which shows that the roles are not mutually exclusive. The two projects however fell short of the collaborative role (development journalism) which can, partly, be attributed to the adversarial nature of the relationship between the state and the media. The Daily Dispatch also failed to activate a platform for deliberation and public problem solving. There might thus be more scope in adopting a 'facilitative monitorial role' which would not only expose those who violate other people's human rights, corrupt people and institutions that are not performing well. Instead it will also activate civic life and facilitate 'collaboration' between government and the publics in problem solving.

- Description: In the Eastern Cape department of Education, there are a variety of failures within the delivery of the school infrastructure. The department is faced with the problem of the infrastructure backlog. The study looked into planning, controls, leadership management style and the locus of control of officials dealing with the delivery of the school infrastructure in the department of education. Objective is to investigate the factors hindering the school infrastructure service delivery in the Eastern Cape Provincial Department of Education. It was imperative that there was a need for more emphasis in ensuring that Education infrastructure planning base stabilized in order to effectively address infrastructure service delivery. The empirical study was conducted through semi-structured questionnaires. The sample was drawn from the infrastructure unit in Zwelitsha offices as well as from the officials that were implementing the infrastructure plans and from officials who provided support and monitoring. The empirical results showed that the department had no credible plans, no sound systems, or controls to track the non- service delivery. Management style was perceived as unconsultative and do not promote good co-operate governance. There is no retention strategy whilst there is a shortage of technical skills. It is recommended that the department should established a cross functional team which gives the strategic direction to the management of the school infrastructure delivery. The team should comprise of the top management of the department and as well the implementing agent and must be chaired by the Head of the department. The management should undergo a developmental training on charisma techniques which is associated with aspiration of officials in order to argument the unconsultative style of management which is perceived as more of instructing. Officials are to be capacited with the technical skills relevant to the built environment. The department should also implement the infrastructure delivery management system (IDMS) as prescribed in the Construction Industry Development Board (CIDB) Toolkit Guide. The Toolkit provides a documented body of knowledge and a set of processes that represent generally recognised best practices in the delivery management of infrastructure (CIDB Toolkit Guide).

- Description: The Department of Social Development, in collaboration with Ngqushwa Local Municipality, administers many community development projects in this local municipality. These projects aim to help local communities alleviate poverty. Scholars of community development advocate for people-centred approach to successful and sustainable community development, thus promoting community participation. Some Department officials have to ensure that community development projects are implemented in needy communities in accordance with development principles. Despite the advantages of these projects, there are challenges that confront their implementation. These projects are too formalised and too discrete, thus curtailing their chances of success and sustainability. Also, due to the complex nature of some of these projects, they are often poorly run, and do not achieve their intended objectives. Consequently, project membership is constantly decreasing. The aim of this study was to investigate the implementation of agricultural projects in Ngqushwa Local Municipality. In investigating these projects, the objectives of the study were to explore the extent of community participation and challenges in the implementation of these projects. In addition, this study sought to provide an understanding into inherent factors that have an impact on the implementation of these agricultural projects. The ultimate aim was to share with community development agents where outdated paradigm regarding implementation of projects is still prevailing and the lessons learnt about holistic and integrated strategies in order to alleviate poverty and improve the quality of life. This study used a qualitative approach in gathering data. It combined the survey of literature and administration of questionnaires in gathering of empirical data. The sampling method used to select participants was purposive, which is the most important non-probability sampling. In this type of sampling, researchers rely on their experience, ingenuity, previous research experience and findings to deliberately obtain units of analysis in such a way that the sample researchers obtain may be regarded as being representative of the relevant population. This iv iv type of sample is based entirely on the judgment of the researcher in that the sample is composed of elements that contain the most characteristics, representative or typical attributes of the population that serve the purpose of the study best. The researcher personally administered the questionnaires to four project members who were unable to read and write. The rest of sixteen project members, three officials who are directly involved in the implementation of agricultural projects in the Department of Social Development and an Office Manager, were given questionnaires to complete. This study revealed that in most instances, decisions have been taken unilaterally by the officials of the Department of Social Development. All the planning for the implementation of agricultural projects is the prerogative of Department officials. The high level of dissatisfaction among project members is likely a direct result of this approach by the Department. Inviting community members to participate in projects when decisions have already been taken, or where there is no meaningful issue to decide on, results in community members losing their interest in projects. It also emerged from the study that the Department of Social Development does not have criteria to select who should be the members of a particular project. This potentially results in deserving community members being excluded. There is a strong sense among project members that poverty alleviation energy is focused on one type of project, rather than looking at other ways to ensure that those who are not interested in food gardens are given alternative opportunities.

- Description: The Department of Social Development, in collaboration with Ngqushwa Local Municipality, administers many community development projects in this local municipality. These projects aim to help local communities alleviate poverty. Scholars of community development advocate for people-centred approach to successful and sustainable community development, thus promoting community participation. Some Department officials have to ensure that community development projects are implemented in needy communities in accordance with development principles. Despite the advantages of these projects, there are challenges that confront their implementation. These projects are too formalised and too discrete, thus curtailing their chances of success and sustainability. Also, due to the complex nature of some of these projects, they are often poorly run, and do not achieve their intended objectives. Consequently, project membership is constantly decreasing. The aim of this study was to investigate the implementation of agricultural projects in Ngqushwa Local Municipality. In investigating these projects, the objectives of the study were to explore the extent of community participation and challenges in the implementation of these projects. In addition, this study sought to provide an understanding into inherent factors that have an impact on the implementation of these agricultural projects. The ultimate aim was to share with community development agents where outdated paradigm regarding implementation of projects is still prevailing and the lessons learnt about holistic and integrated strategies in order to alleviate poverty and improve the quality of life. This study used a qualitative approach in gathering data. It combined the survey of literature and administration of questionnaires in gathering of empirical data. The sampling method used to select participants was purposive, which is the most important non-probability sampling. In this type of sampling, researchers rely on their experience, ingenuity, previous research experience and findings to deliberately obtain units of analysis in such a way that the sample researchers obtain may be regarded as being representative of the relevant population. This iv iv type of sample is based entirely on the judgment of the researcher in that the sample is composed of elements that contain the most characteristics, representative or typical attributes of the population that serve the purpose of the study best. The researcher personally administered the questionnaires to four project members who were unable to read and write. The rest of sixteen project members, three officials who are directly involved in the implementation of agricultural projects in the Department of Social Development and an Office Manager, were given questionnaires to complete. This study revealed that in most instances, decisions have been taken unilaterally by the officials of the Department of Social Development. All the planning for the implementation of agricultural projects is the prerogative of Department officials. The high level of dissatisfaction among project members is likely a direct result of this approach by the Department. Inviting community members to participate in projects when decisions have already been taken, or where there is no meaningful issue to decide on, results in community members losing their interest in projects. It also emerged from the study that the Department of Social Development does not have criteria to select who should be the members of a particular project. This potentially results in deserving community members being excluded. There is a strong sense among project members that poverty alleviation energy is focused on one type of project, rather than looking at other ways to ensure that those who are not interested in food gardens are given alternative opportunities. The findings have also shown that lack of capacity is considered critical in explaining reasons for the failure in the implementation of these agricultural projects.

- Description: The "tabloid TV" genre, like tabloid newspapers has been chastised for depoliticising the public by causing cynicism, and lowering the standards of rational public discourse. Such criticisms are not always based on a close interrogation of the reasons for the popularity of such a genre amongst its consumers. The "tabloid TV" news genre is a relatively new phenomenon in Zambia and in the African context in general. This study is an investigation of the rise in popularity of the Zambian television station, Muvi TV. It is a reception study of Lusaka (capital city) viewers, particularly the working class community, who make up the majority of the TV stations' audience. Members of this social group who have hitherto been marginalised from mainstream media discourses were interviewed. In particular, the study explores the meanings obtained from the content of Muvi TVs' tabloidised main evening news and its relevance to their everyday lived experiences. The TV station gives prominence to "micro-politics of everyday life", alongside "serious" stories albeit in a more lurid, sensationalised and personalised manner. In undertaking this investigation, the study draws primarily on qualitative in-depth interviews - focus group and individual. These techniques unearth the manner in which the viewers decode the messages and appropriate the meanings into their lived experiences. The study establishes that the popularity of Muvi TV is due to the emphasis on human-interest stories epitomised by tabloid journalism values. The working class majority is able to relate and identify with these stories, and attaches greater believability to the station's news as compared to the public broadcaster, the Zambia National Broadcasting Corporation (ZNBC). As such, Muvi TV can be seen to fulfil a political function despite its sensationalised approach.

- Description: The goal of the research paper was to understand the complex relationship between the issue of sustainability and maize farmers’ decision-making processes. The aim is to shed light on the realities experienced by maize farmers in terms of how sustainability impacts on the decisions they make and how the decisions they make impact on sustainability. The importance of the research lies in the current state of affairs in the world in terms of the current economic recession, overpopulation, dire poverty and hunger, and the poor state of the environment. If humankind is to continue its existence on Earth in a happy, healthy world, something is going to have to give. In order for this to happen, people need to start grappling with the concept of sustainability. Focusing on sustainability as a whole is likely to end in despair. However, breaking the problem down into its component pieces will allow people to influence the particular sector in which they operate. It is therefore imperative for research into sustainability to be undertaken in all sectors of society and the economy. Agriculture presents an excellent research area due to its intrinsic link with the environment, society and the economy. Agriculture and its wellbeing is inextricably tied to environmental health. Healthy plants and animals will not grow in unhealthy conditions. Society is to a large degree dependent on agriculture for food, agriculture therefore has a significant impact on social order and function. Agriculture is one of the primary contributors to GDP, particularly in poor and developing nations. As a result, agriculture has an important role to play in ensuring economic sustainability. In order to engage with sustainability from an agricultural perspective it was decided to engage on the farmer-level. Gaining an understanding of their reality in terms of what motivates their decisions is key to understanding the relationship between agriculture and sustainability. Three maize farmers in Mpumalanga, South Africa, were interviewed with the aim of collecting qualitative data and then analysing the data using thematic analysis. The methodology employed enabled the researcher to uncover patterns in the data that constituted themes across the interviews. The following themes emerged: Theme 1: Economic factors are the primary decision driver. This is primarily due to the extent of the financial risk experienced by farmers as a result of market risk, production risk, finance risk, and rising input costs. This results in economic considerations superseding environmental or social concerns in farmers’ decisions. This has a negative impact on the overall sustainability of the farming operation. Theme 2: There has been a decrease in the number of family-run farms. This is attributable to a number of factors including economic failure, fear of loss of land due to land-reform policies, as well as crime. Family-run farms tend to have a greater focus on sustainability due to the vested interest in the next generation taking over the farm. The corporate farming operations that are taking over the farms tend to be more focussed on short-term gains in order to satisfy shareholders. Theme 3: Mechanisation is preferable to manual labour. There has been an alarming decrease in the number of labourers employed on farms. Farmers say this is due to two factors. Firstly, machines are more efficient than labour. Secondly, restrictive labour laws have made famers less keen to employ people. The net effect of these two factors is that unemployment is rising. This has negative consequences for society, the economy, and the environment. Theme 4: Farmers believe they do very little environmental damage. This results in decisions being made that do not consider environmental wellbeing other than soil health. This is because farmers see healthy soil as an integral input that optimises economic performance. Farmers tend to prioritise economic factors in their decisions more than environmental or social factors. This results in an unsustainable perspective. The only ways in which this is likely to change is if the financial risk associated with agriculture is decreased, or if farmers are given financial incentive to change their ways. In order to deal with this issue it is necessary for further research to be conducted. Research needs to be conducted to confirm the results of this study. It is important to know whether the results pertain only to maize farmers in Mpumalanga or whether most farmers in South Africa, and indeed the world, face similar problems. Research should also be conducted to propose policies or procedures to reduce financial risk in agriculture. Research should focus on reducing market risk and reducing input costs, possibly via subsidisation.

- Description: Narcissism is increasingly being regarded as one of the biggest socio-cultural problems of the contemporary era. Indeed, recent studies by Baldwin and Stroman (2007) and Buffardi and Campbell (2008), among others, have advanced that new media technologies – in particular social networking websites – have significantly exacerbated the rise and spread of narcissism in contemporary society. Based on this premise, namely that social media provide the perfect platform for the promotion of self-infatuation, this research project will provide a critical analysis of the potential influence of social media in the development of a widespread narcissistic socio-cultural condition. In this regard, claims that increasingly consumerist, individualist and media-saturated societies are nurturing a culture of extreme narcissism, vanity and entitlement, will be examined in relation to an increase in the use of consumerorientated new media technologies. In particular, by examining the structural components of the popular social networking site, Facebook, this treatise will highlight the connection between the use of this form of new media and the engenderment of an acutely consumerist and narcissistic subjectivity – namely, commodity narcissism. That is, by examining the growth of narcissism from the 1940s through to the new millennium, the role of the media, and most recently new media technologies, in the promotion of commodity narcissism will be examined as factors of particular significance in the formation of contemporary subjectivity. In relation to this, the impact of commodity narcissism on the perpetuation and propagation of capitalist isolation, alienation and insecurity will be investigated with a view to exploring the potential impact of such narcissism on the efficacy of the democratic process. Finally, some remedial measures, which co-opt rather than negate such social media, will be proposed.

- Description: Introduction: Picornaviruses are a family of RNA viruses which are economically and clinically significant. Like many other viruses, picornaviruses utilise host cell machinery to facilitate their replication and assembly, including heat shock proteins (Hsps). The aim of this research was to investigate the role of Hsp40, Hsp70 and Hsp90 during picornavirus infection using the cardiovirus, Theiler’s murine encephalomyelitis virus (TMEV), as a study model. Methodology: Picornavirus VP1 capsid proteins were analysed by multiple sequence alignment and multiple structural comparisons. Protein domain architecture was used to analyse Hsp90 cellular and viral client proteins. Effects of Hsp90 inhibitors, novobiocin and geldanamycin, on TMEV growth in BHK-21 cells was observed over a 48hr period. Localisation of Hsp40, Hsp90 and Hsp70 in TMEV-infected BHK-21 cells was investigated by indirect immunofluorescence and confocal microscopy. Results and Discussion: VP1 proteins of picornaviruses are highly divergent within the family at the amino acid level, which might be linked to the protein’s function in determining virus tropism and antibody neutralisation. An eight-stranded anti-parallel beta-barrel structure was found conserved in the VP1 protein structures which might be linked to the highly conserved picornavirus capsid assembly process. Absence of a common protein domain between Hsp90 viral and cellular client proteins that might be functionally connected to Hsp90, suggests that Hsp90 most likely recognises surface features rather than sequence motifs/patterns. The Hsp90 inhibitors, novobiocin and geldanamycin, had a negative effect on virus growth as virus-induced cytopathic effect was not observed in treated cell after 48hrs. TMEV 2C protein was detected by Western analysis in infected cell lysates treated with geldanamycin but not novobiocin, suggesting novobiocin affects the translation or processing of TMEV 2C. Immunofluorescence analysis of TMEV-infected cells showed a relocalisation of Hsp40 into the nucleus during infection. Overlap of Hsp40 and TMEV P1 was observed in the perinuclear region, suggesting colocalisation between these proteins. Hsp70 converged around the replication complex during infection but did not overlap with TMEV 2C. Hsp90 concentrated in the region of the replication complex where it overlapped with TMEV 2C and this redistribution was found to be dependent on the stage of infection. The overlap between Hsp90 and TMEV 2C signals observed, suggested colocalisation between the two proteins. Conclusion: This study identified Hsp90, Hsp70 and Hsp40 as possible host factors required in TMEV replication.

- Description: The aim of this research was to investigate the socio economic impact of electrification in Mnquma Municipality in the province of Eastern Cape. Mnquma Municipality has a backlog of about 25475 households that have not yet been electrified. There is a high demand of electricity in villages that have not yet been electrified. Eskom Southern Region has about 5 Million electrified households. The year 2012 was declared as year of universal access of electricity in South Africa. In the last three years amount of electrified households has been coming down at alarming rate. It is against this background that the study sought to investigate the socio economic impact of electrification of households. This study is a comparative study where two villages are compared. One village is electrified whilst the other village is not electrified. The study is based on the questionnaire opinion survey where respondents‟ views and opinion are solicited to test if electricity improves the socio economic conditions of Mnquma households. The study confirmed the findings of the research if electrification has improved the socio economic condition and if electricity is a preferred source of energy. The study proposed recommendations encompasses strategic responses to check if Government is achieving the desired goal through electrification of households.

- Description: The aim of this study was to suggest ways to use enterprise risk management (ERM) effectively towards achieving strategic objectives at East London Industrial Development Zone. The results of the research will contribute to the set of tools which business can utilise in effective business planning and achieve sustainability of enterprises. Enterprise risk management provides stakeholders with reasonable assurance that management has taken due care in drawing up strategies aligned with their appetite for risk. The objective was to investigate the utilisation of Enterprise Risk Management at East London Industrial Development Zone. The literature review revealed shortcomings of the traditional risk management strategy. Examples of the shortcomings are its preoccupation with hazard risks and its disconnection with other functions in an organisation. ERM has emerged as the organisation wide approach to the handling of risk. Effectively integrated with strategy-setting and performance management, ERM strengthens opportunity-seeking behaviour by helping directors and managers develop the confidence that they truly understand the risks inherent in the organization’s strategy and have the capabilities in place to manage and monitor those risks. The assessment of risks after the strategy formulation process results in defective risk management. The result could be strategic objectives that are unrealistic and risk management that is just an appendage to performance management. The empirical study consisted of face-to-face interviews using semi-structured questionnaires. The respondents were Business Unit Managers at East London Industrial Development Zone who advised on current practice of ERM in the organization. The main findings of the empirical investigation revealed that ERM started with organisational survival in mind but ended up being a compliance activity. Also, ERM is under-resourced as there are no dedicated ERM financial and human resources. The organization’s unstructured and informal approach to ERM could place the strategic objectives at risk. Recommendations conclude the investigation and address the shortcomings and improvements that can be made to the utilisation of ERM within the organization. The recommendations are ensuring strong commitment towards ERM and widening the participation of all employees in ERM; developing an ERM road map; allocation of resources to ERM initiative; development of a business case for ERM; training of all managers and all employees on ERM; and focusing on low-hanging return, which may result in quicker realisation of the value added by ERM to the organization.

- Description: The aim of this study was to suggest ways to use enterprise risk management (ERM) effectively towards achieving strategic objectives at East London Industrial Development Zone. The results of the research will contribute to the set of tools which business can utilise in effective business planning and achieve sustainability of enterprises. Enterprise risk management provides stakeholders with reasonable assurance that management has taken due care in drawing up strategies aligned with their appetite for risk. The objective was to investigate the utilisation of Enterprise Risk Management at East London Industrial Development Zone. The literature review revealed shortcomings of the traditional risk management strategy. Examples of the shortcomings are its preoccupation with hazard risks and its disconnection with other functions in an organisation. ERM has emerged as the organisation wide approach to the handling of risk. Effectively integrated with strategy-setting and performance management, ERM strengthens opportunity-seeking behaviour by helping directors and managers develop the confidence that they truly understand the risks inherent in the organization’s strategy and have the capabilities in place to manage and monitor those risks. The assessment of risks after the strategy formulation process results in defective risk management. The result could be strategic objectives that are unrealistic and risk management that is just an appendage to performance management. The empirical study consisted of face-to-face interviews using semi-structured questionnaires. The respondents were Business Unit Managers at East London Industrial Development Zone who advised on current practice of ERM in the organization. The main findings of the empirical investigation revealed that ERM started with organisational survival in mind but ended up being a compliance activity.

- Description: In recent years, immense effort has been channelled towards the Information and Technological development of rural areas. To support this development, telecommunication networks have been deployed. The availability of these telecommunication networks is expected to improve the way people share ideas and communicate locally and globally, reducing limiting factors like distance through the use of the Internet. The major problem for these networks is that very few of them have managed to stay in operation over long periods of time. One of the major causes of this failure is the lack of proper monitoring and management as, in some cases, administrators are located far away from the network site. Other factors that contribute to the frequent failure of these networks are lack of proper infrastructure, lack of a constant power supply and other environmental issues. A telecommunication network was deployed for the people of Dwesa by the Siyakhula Living Lab project. During this research project, frequent visits were made to the site and network users were informally interviewed in order to gain insight into the network challenges. Based on the challenges, different network monitoring systems and other solutions were deployed on the network. This thesis analyses the problems encountered and presents possible and affordable solutions that were implemented on the network. This was done to improve the network‟s reliability, availability and manageability whilst exploring possible and practical ways in which the connectivity of the deployed telecommunication network can be maintained. As part of these solutions, a GPRS redundant link, Nagios and Cacti monitoring systems as well as Simple backup systems were deployed. v Acronyms AC Access Concentrators AMANDA Automatic Marylyn Network Disk Archiver CDMA Code Divison Multiple Access CGI Common Gateway Interface.

- Description: The DPS-4D is the latest version of digital ionosonde developed by the UMLCAR (University of Massachusetts in Lowell Center for Atmospheric Research) in 2008. This new ionosonde has advances in both the hardware and software which allows for the promised advanced capabilities. The aim of this thesis was to present results from an experiment undertaken using the Hermanus DPS-4D (34.4°S 19.2°E, South Africa), the first of this version to be installed globally, to answer a science question outside of the normally expected capabilities of an ionosonde. The science question posed focused on the ability of the DPS-4D to provide information on day-time Pc3 pulsations evident in the ionosphere. Day-time Pc3 ULF waves propagating down through the ionosphere cause oscillations in the Doppler shift of High Frequency (HF) radio transmissions that are correlated with the magnetic pulsations recorded on the ground. Evidence is presented which shows that no correlation exists between the ground magnetic pulsation data and DPS-4D ionospheric data. The conclusion was reached that although the DPS-4D is more advanced in its eld of technology than its predecessors it may not be used to observe Pc3 pulsations.

- Description: The study sought to investigate the viability of digital records management in the Office of the Premier (OTP) in the Eastern Cape Province. The objectives of the study were to establish the current status of digital records management in the OTP, determine the compliance with the legal framework, identify the requisite infrastructure for digital records management (DRM), describe the security and preservation measures for DRM, and the challenges of managing digital records. Purposive sampling was used to select 40 participants. A questionnaire was used to collect data. The study revealed that the OTP has taken a number of initiatives aimed at establishing records management practices. However, the study found that the OTP is faced with a number of challenges in trying to use the Electronic Document and Records Management System (EDRMS). The majority of the employees did not have any qualification in records management. This lack of skills and competencies affects the implementation of the new system. The findings of the study showed that most of the employees were resisting using the new system because they were not comfortable with it. The study recommends that the department should encourage its staff to get training to be knowledgeable in the use of EDRMS which generates records; the staff should work closer with the consultancy in order to gain skills and knowledge to facilitate the change process, and the security and preservation of digital records should be enhanced.

- Description: This research project examines a case of environmental training for workers in the Expanded Public Works Programme, a poverty relief programme operating in South Africa (EPWP). It is constituted as an interpretive case study, and explores what workers learn and how they learn in an environmental skills programme. The study also examines the context of learning. In accordance with education and training policy, what learners are meant to learn is articulated in unit standards registered on the South African Qualifications Authority website. The unit standards are used to design curricula and learning programmes which are registered as environmental skills programmes by Sector Education and Training Authorities (SETAs). For the conservation sector the SETA is the Tourism and Hospitality Education and Training Authority (THETA). To develop an understanding of what learners learn, I considered the content, concepts, skills, values and attitudes contained in the unit standards, and then considered the actual learning taking place during the training programme focusing on three unit standards. Data was generated from semi-structured interviews with facilitators, focus group interviews with learners, observations of teaching and learning interventions and document analysis of EPWP, training and skills development policy documents, registered unit standards for the skills programme, and learning support materials produced by the provider implementing the training. The study notes that there is learning taking place within the training implemented through environmental skills programmes. The training is influenced by a number of diverse contextual factors namely policy factors, historical contextual factors, the economic context and diverse literacy levels. Learning interactions involve a variety of social interactions, activities and practices between learners and learners, and learners and facilitators. The main finding of the study is that the training programme’s major emphasis is on concepts and content, and social and learning skills, and values and attitudes. The prominence of social skills masks a neglect of practical workplace related skills which make up a strong focus of the unit standards. This, the study shows, is related to a lack of engagement with workplace learning, which in turn is linked to a disjuncture between policy and practice, where workers working in the EPWP programme are meant to benefit from training, but in this case it was found that community members, who were not working in the programme were being offered training. It was therefore not possible for them to develop the applied workplace skills, which were also meant to facilitate increased employability, as this is one of the key objectives of the EPWP programme. Based on the insights raised by the research findings the study made recommendations that the programme consider the following to recover the situation: to develop strategies that allow for longer term training frameworks so that learners can be trained on full qualifications so that they may qualify and benefit more substantively from the training in terms of employability skills. Facilitators in the programme need to be trained so that they can develop materials that address practical skills, values, attitudes, critical reflections and actions. Monitoring of training needs to be given preference both at materials development level and implementation level.

- Description: The specialised nature of the stratum corneum makes it an efficient barrier to foreign substances, including drug molecules. Therefore, cutaneous drug absorption is a slow and complex process of which stratum corneum penetration is the rate limiting step. The rate and extent of stratum corneum penetration by a drug compound depends greatly on the presence of penetration enhancing/retarding excipients and therefore the clinical outcomes of a product rely greatly on the components and quality of the formulation. Hence, establishing bioequivalence between topical products is crucial to ensure that patients receiving multisource drug products are assured of the same efficacy and safety as the brand product. Since locally acting topical formulations do not target the systemic circulation, conventional methods of assessing bioequivalence using plasma levels are not appropriate. Consequently, the current regulatory guidelines require comparative clinical trials to be carried out to show bioequivalence between topical products. As these studies are very expensive and time consuming, the development of a more direct and relatively rapid and inexpensive method for determining bioequivalence between topical products is required. Clotrimazole is an anti-fungal agent where the target site of action is in the stratum corneum. In this work, tape stripping, which involves the sampling of stratum corneum, was investigated as a tool for the determination of bioequivalence between topical clotrimazole products. The tape stripping method involved the analysis of each tape strip individually and standardization of stratum corneum thickness between subjects was carried out using TEWL measurements. This approach provided detailed information regarding the amount of clotrimazole present in the stratum corneum as well as the extent of drug penetration. Prior to the tape stripping studies an HPLC method was developed for the quantitative analysis of clotrimazole from the tape strip samples. This method was shown to be accurate and reproducible across the required range. It was also shown to be selective for clotrimazole in the presence of possible interfering substances such as those present in the tape adhesive and also skin components. The bioequivalence studies were conducted using a single “uptake” time point. In order to determine an appropriate dose duration for these studies a novel approach was employed, involving a preliminary dose duration study. For the bioequivalence investigations, Canesten® Topical cream was used as both test and reference products to determine if the method was capable of showing bioequivalence. Subsequently, Canesten® Topical cream was also compared to a 1% gel formulation to determine if the method could detect formulation differences. The conventional BE limits of 0.8 – 1.25 were used for the assessment of BE, however, the clinical relevance of using these limits for dermal studies is debatable since they are derived from oral pharmacokinetic studies. Therefore, the data from the tape stripping investigations were also assessed using more realistic limits of 0.75 – 1.33 and even 0.7 – 1.44. In addition to the tape stripping studies a novel method of determining the amount of drug present in the stratum corneum, the “Residual Method”, was investigated. This method involved assaying the amount of clotrimazole found in the residual formulation after a specified dose duration had elapsed and subtracting that amount from the amount of clotrimazole initially applied. The results of tape stripping investigations showed that, if the study is sufficiently powered, tape stripping may be used to determine bioequivalence according to the conventional limits, as well as possibly detect formulation differences between different clotrimazole products. Bioequivalence assessment using the widened intervals showed that fewer subjects were required to achieve a sufficient statistical power. The variability associated with this method was acceptable and tape stripping may therefore have the potential to be used as a BE tool in a regulatory setting for clotrimazole or other antifungal topical formulations. The “Residual Method” also showed promising results as a bioequivalence tool, but further investigation and extensive validation of this method is required before it can be suggested as a regulatory method. The results of these studies have clearly indicated that tape stripping has the potential to be used as an alternative to comparative clinical trails for the assessment of bioequivalence between clotrimazole formulations and also to assess bioequivalence between other antifungal products.

- Description: The significant growth in the South African tourism industry in recent years has placed much focus on the hospitality sector in the country. The hospitably sector performs a vital role in the South African economy, as is the case globally, to provide accommodation to international and national tourists. Guest houses in particular have become one of the fastest growing components of the South African tourism industry. However, operating a guest house is not merely providing a bed, shower and breakfast facility for which a client pays and hopefully returns again in future. Rather, it involves significantly more than providing physical amenities. Not only does a potential entrepreneur require a suitable facility in a well-positioned location, but guest house owners and management must adhere to various strenuous safety, security and service measures, as well as municipal by-laws, in a tough and ever-changing business environment. The central theme and the main objective of this study was to investigate the safety, security, service and legal measures that need to be adhered for the successful management of a guest house in the Nelson Mandela Bay Metro. Together with an outline of the various steps required to start a guest house, a sub-objective was to compile a guest house manual that can be used by new and existing guest house owners and managers to improve their business. The target group was divided into two sections, namely guest house owners and managers on the one hand, and guest house clients on the other - hence two separate questionnaires were developed and used as measuring instrument for the empirical study. The results revealed that clients in the Metro are in general satisfied with the service they receive and safety they experience when staying in guest houses in the Metro. The premises are mostly neat and clean, the towels and bedding are regularly replaced and clean, while the parking bays are sufficient and safe, staff members friendly and approachable, and bookings are done promptly. Over and above the different by-laws to observe, it is the duty of owners and management to provide clients with a safe, secure environment with excellent service, and with sufficient lighting at the entrances, parking and reception areas. All staircases should be steady and iv non-slip, and swimming pools should have secured fencing around and/ or should be covered by safety nets. Staff should follow the correct procedures in emergencies, while concerted efforts should be made to adapt guest houses for the specific needs of disabled and elderly clients. To prevent the outbreak of food poisoning, and to ensure personal and kitchen hygiene, as well as the correct storing of food, are other important responsibilities of owners and management. Therefore, for a guest house to be managed successfully, the owners and management must take into consideration the required safety, security, service and legal measures.

- Description: The significant growth in the South African tourism industry in recent years has placed much focus on the hospitality sector in the country. The hospitably sector performs a vital role in the South African economy, as is the case globally, to provide accommodation to international and national tourists. Guest houses in particular have become one of the fastest growing components of the South African tourism industry. However, operating a guest house is not merely providing a bed, shower and breakfast facility for which a client pays and hopefully returns again in future. Rather, it involves significantly more than providing physical amenities. Not only does a potential entrepreneur require a suitable facility in a well-positioned location, but guest house owners and management must adhere to various strenuous safety, security and service measures, as well as municipal by-laws, in a tough and ever-changing business environment. The central theme and the main objective of this study was to investigate the safety, security, service and legal measures that need to be adhered for the successful management of a guest house in the Nelson Mandela Bay Metro. Together with an outline of the various steps required to start a guest house, a sub-objective was to compile a guest house manual that can be used by new and existing guest house owners and managers to improve their business. The target group was divided into two sections, namely guest house owners and managers on the one hand, and guest house clients on the other - hence two separate questionnaires were developed and used as measuring instrument for the empirical study.
