- Description: National Geographic is a magazine that inspires people to care about the planet through its articles of exploration, education, and conservation. Magazines are a significant source of knowledge and compete with a variety of other media, constantly rethinking where they can improve in comparison to other media. Research in this dissertation shows that some magazines offer high quality imagery for artwork, photos and advertisements, which remains critical for industries and readers. They often offer greater depth than radio, TV, or even newspapers, so that people interested in an analysis of news and events still depend on magazines for informative and general news. People often turn to media—such as television, newspapers, magazines, radio, and Internet—to help them make sense of the many complexities relating to environmental science and governance that (un)consciously shape our lives. Global warming, as a subject, demands both political and personal responses in all parts of the world, and effective decision making at both scales depends on timely, accurate information, according to Shanahan (2009:145). The quality and quantity of journalism about climate change will therefore be key in the coming years. National Geographic comprises a variety of themes, such as environment, science, wildlife, travel and photography. This study is an analysis of the writing and photography related to one theme - global warming. It provides a critical analysis of the coverage of the global warming discourse in one magazine, examined over an eleven-year period from 2000 to 2010. This theme is powerful in that it represents ethical responsibility and concern for nature and our world and the analysis attempts to define the objects of discourse within the coverage, thus, evaluating if the format of the coverage informs and educates the audience about global warming.

- Description: Black youth in South Africa has for decades, been marginalized in development programmes and many young blacks are experiencing poverty. With the advent of the new South Africa in 1994, the government initiated poverty alleviation projects for youth development. These projects offered black youth an opportunity to participate in their own development. The current study aimed at critically analyzing the contribution of a „Poverty Alleviation‟ programme for youth development. The study was conducted at Cala in the Sakhisizwe local municipality in the Chris Hani District of the Eastern Cape. The study utilized qualitative and quantitative research methods and took the form of exploratory research. The study revealed factors that appear to contribute to the ineffectiveness of youth development projects. The identified factors include the lack of participation of project members, lack of a sense of ownership and commitment, insufficient skills and non-use of policy and guiding documents by project members during the implementation stage. Stakeholder participation and sharing of expertise was identified as another important factor in determining the contribution of poverty alleviation projects to youth development. Lastly, the study shows that monitoring and evaluation of the project functions are necessary to ensure that a project like this achieves the desired outcome. A key recommendation made is that project members must be involved and participate fully in all project phases to enhance a sense of ownership and commitment to fellow project members.

- Description: Impact assessment is a requirement for development in many countries across the globe, seeking to inform the decision-maker as to the environmental, social and economic impact of an ongoing or proposed project. Socioeconomic impact assessment (SEIA) is a means of informing decision-makers as to the socioeconomic effects a project could have, or is having, thus contributing to informing adaptive management practices. However, the tendency of socioeconomic impact assessment to highly quantitative economic methods of analysis raises the question of whether the desired results are achieved by the process. The purpose of the research was to determine whether highly quantitative forms of economic analysis are suitable for measurement of impacts in a social context where distributive as well as net impact is important; to critically analyze the method utilized in achieving highly quantitative economic impact assessment results; and lastly to draw conclusions and make recommendations regarding the efficacy of monitoring processes used to inform adaptive management practices. The research was conducted by means of a case study focusing on three SEIAs carried out on the same entity, namely the Addo Elephant National Park. Managed by South African National Parks (SANP), it began expanding its borders in the early 2000s. Funded by the World Bank, SANP was required to carry out a comprehensive Strategic Environmental Assessment (SEA) in 2003 to ensure the expansion did not have negative environmental, social and economic repercussions, and where such consequences were unavoidable, to ensure that mitigation and management thereof was informed by useful monitoring exercises. Given the need for resettlement and issues of economic distributive concern raised in the 2003 SEA, the three socioeconomic impact assessments conducted from 2005 – 2010 as part of the ongoing monitoring exercises formed an ideal framework for answering the primary research questions. The findings indicate that despite consistent terms of reference, different assessors interpret mandates from the commissioning body in different ways, leading to varied applications of the same theory, some methodologically better than others. Economic multiplier analysis was found to be inadequate as a measure of the distributive effects of economic impact. Moreover, a lack of consistency, accountability and transparency in the monitoring process led to three sets of results that were incomparable over time and thus inadequate as a means to inform adaptive management practices. Asymmetries of and between power and expertise in the commissioning body and the assessors led to breakdowns of the assessment process in terms of accountability and integrity and resulted in a failure to properly define the scope of the study and measure the relevant indicators. The following recommendations were made: that the economic multiplier method be complemented by additional methods of analysis when utilized in disparate social contexts where distribution of economic benefit is important; that monitoring practices be systematized at an early stage of the process to ensure comparable results useful in informing ongoing management practices; and that what an assessment measures and how it measures it be clarified with reference to an objective source. Finally, the number of factors for consideration in any impact assessment means that measurement of the full picture suffers resource constraints, emphasizing the need for impact assessment oversight to recognize the deficiencies of the process whilst still acknowledging that ‘some number is better than no number’.

- Description: The South African economy has seen an increase in small businesses since 1994. This increase has been caused by an increase in unemployment rate and government interventions to promote small businesses. The government has through the National Treasury introduced various tax legislations to simplify and facilitate the tax processes that small businesses have to comply with. The discussion contained in this treatise seeks to critically analyse the tax implications for small and micro businesses. One of the small business tax legislations, Small Business Corporations, is discussed in chapter 2. The Small Business Corporation legislation provides for two key concessions to qualifying small businesses. The first concession is the progressive tax rates that are lower than normal tax rates at taxable income level below R300 000. The second concession is the special capital allowances that the qualifying small business is entitled to. The tax amnesty for small businesses was introduced in July 2006 to provide an opportunity to small businesses which were not up to date with their tax affairs, to regularise their tax affairs. Small businesses had to meet certain requirements and pay an amnesty levy ranging from 2 to 5 percent of their taxable income. The tax amnesty on small businesses was not as effective as intended, however a slight increase in the South African taxpayer base was achieved. The voluntary disclosure programme has recently been introduced in November 2010, to provide an opportunity for all businesses to voluntarily disclose their previous defaults without being subjected to criminal prosecution and penalties. The government further attempted to simplify the tax compliance process by introducing turnover tax legislation. The turnover tax provides for a single tax system that does away with the need to account for normal tax, capital gains tax, secondary tax on companies and value added tax. The turnover tax system is optional to qualifying small businesses. The turnover tax is calculated by simply applying a tax rate to taxable turnover. Small businesses need carefully consider whether turnover tax will be beneficial to them. It is not advisable for small businesses that are making losses to adopt turnover tax. Another small business tax legislation that promises to be effective is the venture capital incentive. This legislation provides for deduction of expenditure actually incurred in the acquisition of shares by qualifying businesses. It appears that, given the challenges that small businesses still face, the government still has a lot more to do to simplify the tax process for small businesses.

- Description: Development in this century is facing the critical dilemma brought about by Climate Change and the misuse of natural resources which are being depleted faster than they are being reproduced. Sustainable development offers an on-going call for global action towards mitigating the impact of these changes to ensure that current generations live equitably without infringing on the needs of future generations. Ensuing from Sustainable Development are a variety of initiatives such as Renewable Energy, which are aimed at reducing the amount of greenhouse gases, the main culprits of Climate Change. Many countries around the globe have further tailored Sustainable Development principles into policy and legislation to ensure that development initiatives meet the needs of current generations without compromising those of future generations. This study embarked on a process to evaluate how such policies influence the implementation of Renewable Energy projects in the Nelson Mandela Bay Municipality in Port Elizabeth, South Africa.

- Description: This study aimed to examine the construction of the identity of the participants within the reality TV programmes (Style Her Famous, My Celebrity Home and How Do I Look) as well as examined the representation of that identity as reflected in the change in participants from the beginning to the end of the program. Drawing on literature from fields such as postmodernism and its influence on culture, identity constructions and ordinary people as celebrities, an analysis of the three American reality TV shows Style Her Famous, My Celebrity Home and How Do I Look was conducted. An indepth content analysis with specific reference to comparative analysis further aided this study. A total of 18 episodes (six episodes for each programme) were collected and thoroughly analyzed where the ‘cut and paste identity’ of ordinary people as ‘celebrities’ constituted the hermeneutical key of the study. The episodes and programs have been scrutinized and have been systematically classified to enable an analysis of the observations. This study attempted to not only describe, but also to foster change in the representation of the identity of the participants of the above mentioned reality TV programmes. The study found that reality television plays a role in shaping the postmodern identity of ordinary people as celebrities. The study also found that the participants involved in the above mentioned programmes found it easy to make someone else’s identity their own. It appeared that the postmodern mind is easily influenced and willing to adopt an identity especially that of a celebrity. The participants involved in these programs claimed this identity as their own and then believed that the new identity was in fact who they ‘really are’ but in actual fact it is a beginning of a new sameness with somebody else. Hence the participants possessed a ‘cut and paste identity.’

- Description: In understanding the importance of career adaptability in an individual‟s career development, career counsellors require a valid assessment technique for measuring career adaptability. The Career Adapt-Abilities Inventory (CAI) was originally developed by Mark Savickas (2008) as a measure of career adapt-abilities. The present study forms part of an international collaboration investigating the psychometric properties and construct validity of the CAI. The aims of the present study involved the following: conducting exploratory factor analysis in order to determine whether interrelationships within the items of the CAI can be explained by the presence of unobserved variables; conducting confirmatory factor analysis in an attempt to confirm the hypothesised factor structures of the CAI; and to explore and describe South African university students‟ perceptions of the underlying constructs of the CAI in terms of the language usage and comprehension of the inventory‟s item content. A sample of South African first-year university students were employed in this current study. In an exploratory factor analysis of the CAI, preference was given to the a priori criterion forcing the extraction of five factors. The oblique rotation method was employed using the OBLIMIN method provided by the statistical package in order to derive the simplest and most interpretable factor structure. Exploratory factor analysis supported a five factor solution after the fourth iteration, reflecting the underlying dimensions of Curiosity, Concern, Confidence, Cooperation and Control. These factors support the five scales presented by Savickas (2008). Confirmatory factor analyses were subsequently performed in order to test both the original CAI factor model as well as the factor model that emerged through exploratory factor analysis. After using several goodness-of-fit indices, it can be concluded that the inventory items adequately represent the five CAI scales based on the value obtained using the Root Mean Square Error of Approximation index. The factor model derived through EFA demonstrated a slightly better fit when compared to the original CAI factor model using other fit indices. In terms of the qualitative findings of this current study, participants indicated that the meaning of several items were unclear to them causing comprehension difficulty. Items 8 and 50 were marked by participants several times and can be viewed as the items causing most difficulty with regard to comprehension, with participants pointing out the words „keeping upbeat‟ (item 8) and „conscientious‟ (item 50). Participants were also asked to provide additional comments with regard to the readability, comprehension and applicability of the CAI. On investigation of these comments, three main themes were generated relating to: the comprehension and clarity of the CAI; the CAI enhancing participants‟ understanding of themselves; and the structure, length and general layout of the CAI. In essence, the current study provided useful information regarding the psychometric properties of the CAI using a sample of South African first-year university students. Factor analyses provided some support for the validity of the CAI while the qualitative results provided aspects for consideration in making the CAI more applicable for South African usage. Moreover, a foundation has been laid for further research to be conducted in South Africa regarding the validity and applicability of the CAI for South African populations.

- Description: Energy is of concern for governments and economies all over the world. As conventional methods of energy production are facing the prospect of depleting fossil fuel reserves, economies are facing energy risks.

A shift from intensive fossil fuel consumption to alternative energy consumption combined with the calculated use of fossil fuels needs to be implemented. Using the energy radiated from the sun and converted to electricity through photovoltaic energy conversion is one of the alternative and renewable sources to address the limited fossil fuel dilemma. South Africa receives an abundance of sunlight irradiance, but limited knowledge of the implementation and possible energy yield of photovoltaic energy production in South Africa is available. Photovoltaic energy yield knowledge is vital in applications for farms, rural areas and remote transmitting devices where the construction of electricity grids are not cost effective. In this study various meteorological and energy parameters about photovoltaics were captured in Port Elizabeth (South Africa) and analyzed, with data being recorded every few seconds. A model for mean daily photovoltaic power output was developed and the relationships between the independent variables analyzed. A model was developed that can forecast mean daily photovoltaic power output using only temperature derived variables and time. The mean daily photovoltaic power model can then easily be used to forecast daily photovoltaic energy output using the number of sunlight seconds in a given day.

- Description: Energy is of concern for governments and economies all over the world. As conventional methods of energy production are facing the prospect of depleting fossil fuel reserves, economies are facing energy risks. With this tension, various threats arise in terms of energy supply security. A shift from intensive fossil fuel consumption to alternative energy consumption combined with the calculated use of fossil fuels needs to be implemented. Using the energy radiated from the sun and converted to electricity through photovoltaic energy conversion is one of the alternative and renewable sources to address the limited fossil fuel dilemma.

- Description: The Eastern Cape Provincial Administration has, since the promulgation of the Supply Chain Management Policy Framework in 2003, been challenged with the implementation of the said Policy.Some departments have progressed better than others, but all of the provincial departments have been challenged in one way or another.It was therefore, necessary to research the reasons for the erratic implementation process by the different departments. An analysis, based on answers provided by senior officials of the Eastern Cape Provincial Administration in an interviewing process, was needed to get an understanding of the challenges the departments are faced within the implementation process. In order to provide quality goods and services, this dissertation aims to evaluate the implementation process, provide insight to the challenges that the departments are faced with and offer recommendations on how to remedy these challenges. The lessons learned from this research study will assist the provincial departments to re-engineer their implementation processes and move forward to greater success and embracement of the Supply Chain Management policy Framework.

- Description: Information Communication Technology (ICT) practitioners and Enterprise Resource Planning (ERP) specialists are highly sought after globally and in South Africa. In order to address this need for ERP specialists, several studies propose that ERP systems should be adopted in the Information Systems (IS) curricula in higher education institutions (HEIs) for instructional purposes. Whilst many HEIs in the United States, Australia and Europe have successfully adopted ERP systems into their curricula, less than 30% of South African HEIs have followed this trend. The adoption of ERP systems is a challenging process as such systems are resource-intensive, costly, complex, and have a steep learning curve. Educators are faced with resource problems and a dearth of options relating to the adoption process. In addition it is critical that the skills and knowledge competencies attained in these courses are industry-relevant. Several education frameworks have been recommended to assist educators with the process of adopting an ERP system in the curriculum, but these frameworks are not comprehensive since they do not consider all the factors relating to the adoption of an ERP system. In addition existing frameworks are not based on industry-relevant competencies but rather on educational objectives. This has resulted in a difference between the competencies required by organisations and those produced by higher education. Whilst there are several research studies on ERP education, empirical studies on frameworks supporting the adoption of ERP systems in HEIs for instructional purposes are limited, particularly on the impact of these frameworks on educational outcomes. The impact of the usability of the ERP system on educational outcomes has also not been fully explored. A survey of ERP consulting organisations in South Africa confirmed that these organisations struggle to obtain ERP specialists with the appropriate competencies. The survey results also contributed to a standardised, comprehensive, set of industry-relevant ERP competencies. The competency set forms part of a comprehensive Competency Framework for ERP System Adoption in IS Higher Education (ERPEd), which can assist educators with the decisions relating to the adoption of an ERP system into the IS curriculum. It includes all the categories of competencies relevant to industry and maps these onto a recommended ERP system adoption approach, an ERP learning tool, as well as the appropriate level of adoption. The application of the ERPEd framework to a case study, the Management Information Systems (MIS) course at the Nelson Mandela Metropolitan University (NMMU), resulted in the adoption of the SYSPRO medium-sized ERP system into the MIS course with the hands-on approach. The empirical results of the evaluation of the case study revealed that the hands-on use of a medium-sized ERP system, SYSPRO, can successfully contribute to the attainment of educational outcomes. These outcomes were mapped to the three core competencies addressed by the MIS course, which were ERP Theory and Concepts, ERP Transactions and Business Process Management (BPM). The educational outcomes evaluated were the measures of performance, self-efficacy and usability. Self-efficacy included satisfaction with the adoption approach. The results were positive in terms of all the metrics of performance, and all three competency categories had positive post-intervention self-efficacy ratings. In terms of growth in self-efficacy from pre-intervention to post-intervention, BPM was the only competency category that did not show a significant growth, however the satisfaction data indicated that students found that the use of SYSPRO improved their competencies in business process understanding. Usability was evaluated in terms of navigation, presentation and learnability. Learnability was the only usability measure in the neutral range, with the other measures falling in the positive range. This confirms related studies reporting that ERP systems are not designed for learning. Overall the students enjoyed the practical application of the theory by using SYSPRO. Several positive and negative features of the user interface were provided which can be used in the design of improved ERP systems for instructional purposes. The results of this investigation can assist in narrowing the gap between industry requirements and IS education programmes. The ERP competency set provides a standardised list of skills and knowledge which is the starting point for any skills improvement program. The ERPEd framework can improve the quality of ERP courses and the competencies of IS graduates. This in turn, can benefit the business community since it will improve the chances of ERP project success. This research is a major contribution to both government and academic initiatives in South Africa to address both the ICT skills problem as well as the need for ERP specialists.

- Description: Nowadays information is everywhere. Organisations process, store and create information in unprecedented quantities to support their business processes. Similarly, people use, share and synthesise information to accomplish their daily tasks. Indeed, information and information technology are the core of business activities, and a part of daily life. Information has become a crucial resource in today‘s information age and any corruption, destruction or leakage of information can have a serious negative impact on an organisation. Thus, information should be kept safe. This requires the successful implementation of information security, which ensures that information assets are only used, modified and accessed by authorised people. Information security faces many challenges; and organisations still have not successfully addressed them. One of the main challenges is the human element. Information security depends to a large extent on people and their ability to follow and apply sound security practices. Unfortunately, people are often not very security-conscious in their behaviour; and this is the cause of many security breaches. There are a variety of reasons for this such as a lack of knowledge and a negative attitude to security. Many organisations are aware of this; and they attempt to remedy the situation by means of information security awareness programs. These programs aim to educate, train and increase the security awareness of individuals. However, information security awareness programs are not always successful. They are not a once-off remedy that can quickly cure information security. The programs need to be implemented effectively, and they require an ongoing effort. Unfortunately, this is where many organisations fail. Furthermore, changing individuals‘ security behaviour is difficult due to the complexity of factors that influence everyday behaviour. In view of the above, this research project proposes an alternative approach in the form of a personal information security agent. The goal of this agent is to influence individuals to adopt more secure behaviour. There are a variety of factors that need to be considered, in order to achieve this goal, and to positively influence security behaviour. Consequently, this research establishes criteria and principles for such an agent, based on the theory and practice. From a theoretical point of view, a variety of factors that influence human behaviour such as self-efficacy and normative beliefs were investigated. Furthermore, the field of persuasive technology has provided for strategies that can be used by technology to influence individuals. On the practical side, a prototype of a personal information security agent was created and evaluated through a technical software review process. The evaluation of the prototype showed that the theoretical criteria have merit but their effectiveness is largely dependent on how they are implemented. The criteria were thus revised, based on the practical findings. The findings also suggest that a personal information security agent, based on the criteria, may be able to positively influence individuals to be more secure in their behaviour. The insights gained by the research are presented in the form of a framework that makes both theoretical and practical recommendations for developing a personal information security agent. One may, consequently, conclude that the purpose of this research is to provide a foundation for the development of a personal information security agent to positively influence computer users to be more security-conscious in their behavior.

- Description: A household survey of Helenvale Township in Port Elizabeth was conducted in order to gain an understanding of the strategies and activities that people in this poor community employ to sustain their livelihoods. The household profile, which entailed a survey of the household size, education levels and employment status was conducted. Dwelling units in terms of ownership, type, size, quality and building materials were also assessed. The income and expenditure of the Helenvale residents and community assets, as well as access to basic services were also assessed. The study found that the household size varied between 5 and 7 members. A more or less even distribution of the gender of household heads was noted, with 48 percent and 50 percent female male respectively. Among the HHs surveyed, no member had a higher qualification than Matric and quite a number were illiterate. Unemployment which stands at 54 percent was identified as the most serious problem plaguing Helenvale. A high level of home ownership (84 percent) was noted; of which 79 percent are formal dwellings and typically two-room structures of poor quality. Helenvale residents are largely dependent on child support grants as the major source of income. Casual jobs and disability grants are the other important sources of income identified. Human assets in the form of labour power are the most important assets that the community possesses. Physical assets are negligible, while financial ones are non-existent among all the respondents. Television and electric kettles are the most commonly owned appliances in the households. Basic services are readily accessible to the community, particularly water, health, refuse removal and sewage. Among the threats that the respondents identified, unemployment came to the fore as the biggest and major threat to households. Crime, teenage pregnancy and overcrowding are also considered as major threats, as are gangsterism and gambling violence. The study recommends the development of a long term plan for poverty alleviation. The creation of employment opportunities in the form of financing of small community projects which empower women and the youth is also recommended. All this should be underpinned by the expeditious delivery of housing.

- Description: It is estimated that each direct job in the automotive industry supports at least 5 indirect jobs in the global community, resulting in more than 50 million jobs to the global auto industry (Ellis, 2006). In South Africa the automotive sector, as an employer, is widely viewed to be second only to mining. In the automotive industry globally, it is being discovered that knowledge, as opposed to “data” or “information”, is becoming harder to locate as a knowledge-bleed is occurring due to the phenomenon of the “brain drain”, retirement of experienced professionals, changing work behaviours among the younger generations and the general lack of infusion of new talent into the South African automotive industry over the past decade (Liebowitz, 1999). This realisation has spawned a growing interest in the concept of knowledge management (KM). KM is the development of tools, processes, systems, structures and cultures explicitly to improve the creation, sharing and use of knowledge critical for decision making. The effective use of KM helps organisations to improve the quality of their decision making and correspondingly to reduce costs and increase efficiency (Kinicki and Kreitner, 2008). Most automotive Original Equipment Manufacturers (OEMs) have made some attempt at KM initiatives, and these attempts have been well-documented. However, among the automotive component suppliers, limited evidence exists of attempts at KM (Piderit, 2007). No standard KM application framework could be established in the literature for industry practitioners in automotive component manufacturers within the Eastern Cape. The aim of this research study is therefore to develop a framework for the application of KM in automotive component manufacturers within the Eastern Cape. The research consisted of a study of the knowledge management literature and the subsequent development of a knowledge management framework and empirical evaluation of the framework in the automotive component supply industry of the Eastern Cape. In conclusion the report presents a knowledge management framework which converts a company assessment to recommended corrective actions to be implemented and also presents the author’s findings, conclusions and recommendations derived from the study.

- Description: This thesis examines the processes of policymaking in South Africa, as expressed through the shifts in income maintenance policy. The thesis focuses on the processes leading to the establishment of the South African Social Security Agency (SASSA), as its case study. SASSA is the institutional framework for the delivery of social grants. Our intention is to test the efficacy of what we have called ‘state learning’ in the South African context. Therefore, the overall aim of the study is to assess the capacity of the ‘state to learn’ in the process of policymaking as expressed through the shifts in social grant administration and the institutional framework of social welfare in South Africa. The subsidiary goals of the research includes mapping changes in the system of social grants administration since 1994 in order to assess the sources of the shifts in its institutional framework; to assess processes and responses within the state that result in policy shifts and the extent to which these can be considered dimensions of state learning; to assess the power of ideas in the policymaking process and to assess the influence of non-state agencies/actors in policy contestation and learning processes. This is essential, because social policy, especially welfare policy research in post-apartheid South Africa, has focused on the economic value of policies and not the political processes in policymaking. For the framework of analysis the study draws on theories of learning, especially at the organizational or institutional level. We start from the perspective that policymaking and implementation cannot be reduced to a neatly ordered schema (Lamb: 1987:6). Further, that policy change and policymaking are “iterative, haphazard, and highly political processes, in which the apparently logical sequences of decision-making, may turn out to be the reverse” (Lamb, 1987:6). This is mainly because state building is a complex affair and a contested terrain; policy learning and making are neither benign nor do they involve the state working in isolation (Sabatier, 1998). To understand processes of policymaking in South Africa, we rely on content analysis of primary and secondary materials or documents and in-depth interviews with key informants involved in the policy process. The documentary sources include records of parliamentary debates, green and white papers on social welfare, ANC party documents, presidential task force reports, newspapers, magazines and court judgments. The study reveals that the establishment of SASSA lends itself to the idea of ‘state learning’. Learning is indicated in South Africa by the capacity and ability of the state to stimulate ideas, debate ideas to establish ideational matrixes as well as paradigms that have informed the development of policy, take ideas and implement them to try and solve mismatches between the intention of the state and the outcomes and the ability of the state to produce policy.

- Description: This thesis examines the processes of policymaking in South Africa, as expressed through the shifts in income maintenance policy. The thesis focuses on the processes leading to the establishment of the South African Social Security Agency (SASSA), as its case study. SASSA is the institutional framework for the delivery of social grants. Our intention is to test the efficacy of what we have called ‘state learning’ in the South African context. Therefore, the overall aim of the study is to assess the capacity of the ‘state to learn’ in the process of policymaking as expressed through the shifts in social grant administration and the institutional framework of social welfare in South Africa. The subsidiary goals of the research includes mapping changes in the system of social grants administration since 1994 in order to assess the sources of the shifts in its institutional framework; to assess processes and responses within the state that result in policy shifts and the extent to which these can be considered dimensions of state learning; to assess the power of ideas in the policymaking process and to assess the influence of non-state agencies/actors in policy contestation and learning processes. This is essential, because social policy, especially welfare policy research in post-apartheid South Africa, has focused on the economic value of policies and not the political processes in policymaking. For the framework of analysis the study draws on theories of learning, especially at the organizational or institutional level. We start from the perspective that policymaking and implementation cannot be reduced to a neatly ordered schema (Lamb: 1987:6). Further, that policy change and policymaking are “iterative, haphazard, and highly political processes, in which the apparently logical sequences of decision-making, may turn out to be the reverse” (Lamb, 1987:6). This is mainly because state building is a complex affair and a contested terrain; policy learning and making are neither benign nor do they involve the state working in isolation (Sabatier, 1998). To understand processes of policymaking in South Africa, we rely on content analysis of primary and secondary materials or documents and in-depth interviews with key informants involved in the policy process. The documentary sources include records of parliamentary debates, green and white papers on social welfare, ANC party documents, presidential task force reports, newspapers, magazines and court judgments. The study reveals that the establishment of SASSA lends itself to the idea of ‘state learning’. Learning is indicated in South Africa by the capacity and ability of the state to stimulate ideas, debate ideas to establish ideational matrixes as well as paradigms that have informed the development of policy, take ideas and implement them to try and solve mismatches between the intention of the state and the outcomes and the ability of the state to produce policy.

A legal-comparative study of the interpretation and application of the doctrines of the sham and the alter-ego in the context of South African trust law: the dangers of translocating company law principles into trust law

- Description: This thesis analyses the doctrines of the sham and the alter-ego and their application to the law of trusts in South Africa. Following an initial examination of the historical development of the law of trusts in English law and the principles of equity law, the study focuses on the current legal status of the trust inter vivos in South Africa and the similarities to its English forerunner. The work traces the sham doctrine back to its origins in English law, where the term “sham” was first used in the context of fraud and dishonesty in cases involving matters arising from hire-purchase agreements, and explains how it gradually began to find its place in the law of trusts. During the exploration, the work highlights the cornerstone of the sham doctrine’s development, the Snook test, which in effect became the internationally accepted guideline for any sham trust enquiry. In terms of the alter-ego doctrine, the work highlights the birth of the principle in Australian law and the doctrine’s immediate reception into other common law jurisdictions and its resultant development. The growth, maturity and popularity of the doctrines are key to the thesis and, in the course of the investigation, the study provides a legal-comparative analysis of the treatment of the doctrines in the context of trusts against that in other common law countries. The study then shifts its focus to South Africa’s interpretation and application of these doctrines in trust law, and reveals the erroneous judicial development in which the courts have in some instances mistakenly replaced the sham doctrine with the company law doctrine of piercing the corporate veil or, in other instances, have erroneously conflated the two trust doctrines. The results highlight a breach of a fundamental rule observed overseas – the “no half way house” rule, which specifically cautions against South Africa’s chosen direction when allowing the lifting of a trust’s veil. The study closes with suggestions as to how the country could reconcile the problems underlined in the thesis by means of law reform, as well as offering practical advice for settlors, trustees and beneficiaries, the core of which is given in the handbook that accompanies this thesis.

- Description: Lean manufacturing has seen its creators, Toyota, rise from insignificance in the middle of the previous century, to the biggest selling car manufacturer in the world today. Another Japanese car manufacturer, Honda, which has also been practising the principles of lean avidly during the last few decades, has also made huge strides towards becoming a dominant force in the car market. These Japanese companies‟ adoption of lean has seen many of their mass producing United States (US) and European counterparts struggle for survival. Maynard (2003:10) predicted that by the end of the decade, at least one of the „Big Three‟ auto makers in the US – Chrysler, Ford, and General Motors (GM) – would be forced to undertake significant restructuring to continue in operation. At the time of this writing all indications are that this prediction will come true. GM is in the process of major shareholding restructuring in an attempt to keep the company afloat, having run up insurmountable debts in the face of the current global economic downturn. Adopting the lean methodology has become a matter of necessity. The continued use of mass production methods alone is no longer viable; companies need to also employ lean methods intelligently in order to remain competitive. This study is regarded as a crucial endeavour to assist operations managers of manufacturing concerns in developing lean implementation strategies which will maximise the benefits to the organization.

- Description: The human being is commonly considered as being the weakest link in information security. Subsequently, as information is one of the most critical assets in an organization today, it is essential that the human element is considered in deployments of information security countermeasures. However, the human element is often neglected in this regard. Consequently, many criminals are now targeting the user directly to obtain sensitive information instead of spending days or even months trying to hack through systems. Some criminals are targeting users by utilizing various social engineering techniques to deceive the user into disclosing information. For this reason, the users of the Internet and ICT-related technologies are nowadays very vulnerable to various social engineering attacks. As a contribution to increase users’ social engineering awareness, a model – called SERUM – was devised. SERUM aims to cultivate social engineering resistance within a community through exposing the users of the community to ‘fake’ social engineering attacks. The users that react incorrectly to these attacks are instantly notified and requested to participate in an online social engineering awareness program. Thus, users are educated on-demand. The model was implemented as a software system and was utilized to conduct a phishing exercise on all the students of the Nelson Mandela Metropolitan University. The aim of the phishing exercise was to determine whether SERUM is effective in cultivating social engineering resistant behaviour within a community. This phishing exercise proved to be successful and positive results emanated. This indicated that a model like SERUM can indeed be used to educate users regarding phishing attacks.

- Description: Novel oxovanadium(IV) complexes of glycine, ʟ-alanine, 1-methylimidazole-2-carboxylic acid, imidazole-2-caboxylic acid and imidazole-4-carboxylic acid were synthesized and isolated in the solid state. The ligands and complexes were characterized by elemental analysis, melting point, NMR, IR and UV-vis spectroscopy. The IR studies showed that glycine and ʟ-alanine coordinate monodentately through the amine nitrogen whilst the imidazole-carboxylic acid derivatives assume a bidentate chelation. The electronic spectroscopic studies indicate distorted octahedral geometry for the oxovanadium complexes of amino acids and a square pyramidal geometry for oxovanadium(IV) complexes of imidazole carboxylic acid derivatives. The reaction of vanadyl (VO2+) with glycine, ʟ-alanine, imidazole-2-cabrboxylic acid, imidazole-4-carboxylic acid and 1-methylimidazole-2-carboxylic acid was studied in aqueous solution by pH-potentiometry under oxygen and carbon dioxide-free conditions. The data obtained from these titrations were used to calculate the protonation and stability constants. The results showed that all ligands are suitable for bidentate coordination in the formation of monomeric species although the solid state studies of the oxovanadium(IV) complexes of amino acids showed a monodentate coordination. The overall stability constants for the (VIVO)-ʟ-alanine system (log β120 = 18.27(6)), (VIVO)-glycine system (β120 = 17.22(6)), (VIVO)-imidazole-4-carboxyic acid (β120 = 11.38(8)), (VIVO)-imidazole-2-carboxylic acid (β120 = 11.62(6)) and (VIVO)-1-methylimidazole-2-carboxylic acid (β120 = 15.49(9)) were obtained. The calculations for the species distribution in the experimental pH range showed that the neutral bis-coordinated complexes are dominant over the biological pH range. The glucose uptake effect of oxovanadium(IV) complex of ʟ-alanine, imidazole-4-carboxylic acid, imidazole-2-carboxylic acid and 1-methylimidazole-2-carboxylic acid was investigated using 3T3-L1 adipocytes, Chang liver and C2C12 muscle cells at various concentrations. The compounds had significant glucose uptake on Chang liver cells only at a concentration of 0.1-10 μM whilst in the C2C12 muscle and 3T3-L1 cells the compounds showed little to no activity probably due to the lower concentrations employed as a result of the cytotoxicity of these compounds on these two cell lines.

- Description: FundaWethu is reading software that is designed to deliver reading lessons to Grade R-3 (foundation phase) children who are learning to read in a multilingual context. Starting from a premise that the system should be both educative and entertaining, the system allows literacy researchers or teachers to construct rich multimedia reading lessons, with text, pictures (possibly animated), and audio files. Using the design-based research methodology which is problem driven and iterative, we followed a user-centred design process in creating FundaWethu. To promote sustainability of the software, we chose to bring teachers on board as “co-designers” using the lesson authoring tool. We made the authoring tool simple enough for use by non computer specialists, but expressive enough to enable a wide range of beginners reading exercises to be constructed in a number of different languages (indigenous South African languages in particular). This project therefore centred on the use of designbased research to build FundaWethu, the design and construction of FundaWethu and the usability study carried out to determine the adequacy of FundaWethu.

- Description: Psychobiographies offer the illuminating experience of uncovering the story of an individual’s life through the lens of a psychological theory. Psychobiographies offer the chance to gain a deeper understanding of what makes that individual unique. This study aimed to explore and describe the emotional intelligence of Archbishop Emeritus Desmond Tutu according to Goleman’s (1998) theory of Emotional Intelligence. Tutu was chosen as a subject for this study because of his extraordinary life and accomplishments, and because he is regarded as a prominent figure of moral leadership in South Africa. A qualitative psychobiographical research method was utilised. Data was collected from both primary and secondary sources to enhance internal validity, and was then analysed according to Miles and Huberman’s (1994) approach. The findings suggest that Tutu applied all of the twenty five emotional intelligence capacities during his life, and that at times, some were used more extensively than others. This study is groundbreaking in that it is the first psychobiography on Desmond Tutu, and it is the first psychobiography undertaken at the University of Fort Hare. Psychobiographies offer an opportunity to evaluate the psychological theory which is applied. It was found that Goleman’s (1998) theory of Emotional Intelligence is supported by this study.
