- Description: Over the last 10 years the South African fiscus has introduced numerous changes to the Income Tax Act (ITA) which affect the income tax implications of persons ceasing to be a resident of South Africa. The two main changes were: - The introduction of a world-wide basis of taxation for residents - The introduction of capital gains tax (CGT) as part of the ITA The aim of this treatise was to identify the income tax implications of persons ceasing to be a resident of South Africa. Resulting from this research, several issues in the ITA have been identified, and the two major ones are summarised below. Firstly, upon the emigration of the taxpayer, there is a deemed disposal of a taxpayer’s assets in terms of paragraph 12 of the Eighth Schedule. It is submitted that the resulting exit tax may be unconstitutional for individuals. It is recommended that South Africa should adopt the deferral method within its domestic legislation for individuals who are emigrating. The deferral method postpones the liability until the disposal of the asset. Secondly, on the subsequent disposal of assets by former residents where there was no exit charge in terms of the exemption under paragraph 12(2)(a)(i) of the Eighth Schedule. Depending on the specific double tax agreement (DTA) that has been entered into with the foreign country, taxpayers have been given vii the opportunity to minimise or eliminate the tax liability with regard to certain assets. This should be of concern from the point of view of the South African government. Further issues noted in this treatise were the following: - It is submitted that the term ‘place of effective management’ has been incorrectly interpreted by SARS in Interpretation Note 6. - It is further submitted that the interpretation by SARS of paragraph 2(2) of the Eighth Schedule is technically incorrect. The above issues that have been identified present opportunities to emigrants to take advantage of the current tax legislation. It is further recommended that taxpayers who are emigrating need to consider the South African domestic tax law implications, respective DTA’s, as well as the domestic tax laws of the other jurisdiction, not only on the date of emigration but also on the subsequent disposal of the respective assets.

- Description: The automotive industry in South Africa exists in its current state due to the developmental programmes created by the South African government. During the next three years the government’s main development policy for the automotive industry will change from the Motor Industry Development Programme (MIDP) to the Automotive Production and Development Programme (APDP). As a result of this change there were feelings of uncertainty experienced across the domestic automotive industry during the APDP’s design and the period leading up to its launch, more or less years 2008 to 2010. Also present is the fear that the industry would collapse when faced with global competition should this change not fully comprehend all aspects of South Africa’s automotive industry. The research problem addressed in this study was to determine the effect on the sector’s competiveness in light of the impending change in governmental development programmes. This was accurately explained and expressed clearly while sub problems were identified from areas in the main problem that required further analysis due to their criticality or lack of clarity. A comprehensive literature review was executed to understand the nature and extent of the South African automotive industry, the Motor Industry Development Programme and the Automotive Production and Development Programme. A primary research instrument was constructed, in the form of a questionnaire, to test specific themes exposed during the literature review which can influence the sector’s competitive advantage. This questionnaire was distributed with the assistance of industry representative bodies NAAMSA (National Association of Automobile Manufacturers of South Africa, the domestic de facto representative body) and NAACAM (National Association of Automotive Component and Allied Manufacturers, a component manufacturers’ representative body), to an even spread of respondents representative of the senior management and executives of automotive companies in South Africa. From the results obtained from the sample group, it seemed that there was consensus on many issues regarding the current structure of the South African automotive industry. Specifically, the profitability of vehicle assemblers and component manufacturers is heavily iii influenced by the incentives offered under the MIDP and the industry is not viable without them. The respondents were virtually unanimous in indicating that there is a need for some form of incentive programme and were positive about the effect the MIDP has had thus far on the automotive industry of South Africa, particularly the effect on the structure, focus and encouraging a reduction in complexity. The research found that it is common practice for OEMs to include the import duty on vehicles imported for domestic consumption even though this duty will be paid with the use of import-duty rebate credit certificates (IRCCs), which are provided to those vehicle assemblers who are net exporters of vehicles. Looking to the future, it emerged that the APDP will have a similar, positive effect on the domestic automotive industry when compared to the MIDP, but the effect will be experienced in a more aggressive manner. Companies will be encouraged by the new development programme to more aggressively improve aspects such as restructuring, rationalising, reducing model proliferation and improving low scale economies for example. Also the APDP will encourage OEMs to increase plant production volumes and ensure that reasonable scale economies are present to develop a domestic component supply industry to a degree. However, the volumes will be insufficient to create a world-class supplier industry. As a result automotive companies will have to be more aggressive in their adoption of more automated production processes and through Automotive Investment Scheme capital investment will increase in both vehicle assemblers and component manufacturers. Component manufacturers indicated that they would invest more in the coming years under the APDP than previously while vehicle assemblers indicated that their investment levels will remain as before. While this is good for the industry, labour is somewhat left out of this: considering the APDP’s focus on increased volumes and capital investments automotive companies are not incentivised to make use of labour-absorbing production processes. The study also found that there is still a need for tariff protection and that the domestic industry would collapse in the face of global competition. The research found that the APDP was compliant with South Africa’s commitments to the World Trade Organisation. Finally, the Department of Trade and Industry’s goal of producing 1.2 million vehicles per annum by 2020 was revealed to be unrealistic and unreachable.

- Description: On May 16 2006 the government of Zimbabwe embarked on a clean-up programme of urban centres, destroying informal human settlements and informal businesses. This operation, which the government called operation "Restore Order", resulted in the displacement of nearly one million people and left thousands of families homeless. This study is a discussion and an analysis of the coverage of the clean-up operation by two of Zimbabwe's leading Sunday newspapers, The Sunday Mail and The Standard. The Sunday Mail is owned by the Zimbabwe government and The Standard is privately owned and perceived to be oppositional to the current Zimbabwe government. The two newspapers, therefore, covered the clean-up operation from different perspectives and often presented conflicting reports explaining why the clean-up operation was carried out and the extent of its impact on the lives of millions of Zimbabweans. The chosen research approach is the Critical Discourse Analysis (CDA) framework as developed by Fairclough (1995). Using CDA, this study seeks to find out and expose the underlying ideological struggles for hegemony between different social and political groups in Zimbabwe and how the newspapers became actors in this process. This process is made possible by looking at how news reporting is organised in the two newspapers, issues of language use, sourcing and external factors that influenced the coverage of the operation.

- Description: The Steiner/Waldorf school movement is currently one of the fastest growing independent school movements internationally. In several countries it seems to have developed into the most popular form of alternative education. South Africa has 17 Waldorf schools and one full-time teacher training facility. This study investigated the interpretation and implementation of the Parzival main lesson within the wider context of the Waldorf curriculum. The main lesson system is an essential constituent of the Waldorf curriculum. Most academic subjects in a Waldorf school are taught in a three- or four-week main lesson block. The main lesson occupies the first two hours of the school day. A main lesson consists of a particular three-part structure, and the main lesson book is the keystone to the Waldorf evaluative process. The Parzival main lesson is specifically taught in Class 11, and most Waldorf schools consider it as one of the most important main lessons in the high school. The interpretivist model was ideally suited to this research. The investigation was conducted as a multiple case study, and the main source of data was provided by classroom observation. This was supported by interviews and classroom artifacts. The study involved two South African Waldorf schools at which the Parzival main lesson is taught. This main lesson is presented at only three South African Waldorf schools. I teach at the remaining school, and therefore conducted my research at the other two schools. The teachers who facilitated the Parzival main lesson, as well as the Class students at the selected schools voluntarily participated in the research. My research findings indicate that the possibility exists for the teacher to exercise a certain degree of freedom and creativity within the parameters of Waldorf methodology and the Waldorf curriculum. The study also determines that teachers often find it difficult to integrate the three-part structure, as indicated by Waldorf methodology, in a single main lesson. Furthermore, my research establishes that main lesson books can indeed serve as both text and as an assessment tool. I therefore conclude and maintain in this study, with particular reference to the Parzival main lesson, that despite the prescriptive structure of the Waldorf system and Steiner pedagogy, teachers need not necessarily sacrifice their freedom and creativity within the classroom.

- Description: This study attempts to make a contribution to the critique of contemporary capitalism. This has been conceptualised through a Foucauldian critique of neo-liberalism, that is, Foucault’s concepts of power and governmentality have been used to criticise neo-liberalism. The study argues that neo-liberalism is a hegemonic and oppressive politico-economic social system. This has occurred in two ways; firstly, neo-liberalism came to dominate the global economy and, secondly, neo-liberalism has become the dominant politico-economic discourse. An attempt is made to expose the discourses and institutions that buttress the neo-liberal project by undertaking a Foucauldian critique. According to Foucault, knowledge shapes the social space through its ‘mechanisms’, discourses and institutions. In order to critique neo-liberalism, it is necessary to expose its power-knowledge base, which is what gives it legitimacy. By analysing and exposing neo-liberalism’s power-knowledge base, its oppression becomes clear through an observation of the material effects of neo-liberal ideology and policy. This study also evaluates to what extent Marxism is a viable alternative to neo-liberalism, in order to ascertain what Foucault adds to already existing critiques of capitalism, and neo-liberalism, in particular. It concludes by arguing that even though Marxism provides a useful framework in which to understand neo-liberal domination, its labour based social theory is somewhat outdated in our contemporary age of the information society. Therefore, it is Foucault’s concept of power-knowledge that is most pertinent in providing an effective critical theory of neo-liberalism in the age of the information society, as it focuses on the primacy of power-knowledge in matters of domination.

- Description: The widely accepted standards of Service-Oriented Architecture (SOA) have changed the way many organisations conduct their everyday business. The significant popularity of mobile devices has seen a rapid increase in the rate of mobile technology enhancements, which have become widely used for communication, as well as conducting everyday tasks. An increased requirement in many businesses is for staff not to be tied down to the office. Consequently, mobile devices play an important role in achieving the mobility and information access that people desire. Due to the popularity and increasing use of SOA and mobile devices, Mobile Service-Oriented Architecture (Mobile SOA) has become a new industry catch-phrase. Many challenges, however, exist within the Mobile SOA environment. These issues include limitations on mobile devices, such as a reduced screen size, lack of processing power, insufficient processing memory, limited battery life, poor storage capacity, unreliable network connections, limited bandwidth available and high transfer costs. This research aimed to provide an elegant solution to the issues of a mobile device, which hinders the performance of Mobile SOA. The main objective of this research was to improve the effectiveness and efficiency of Mobile SOA. In order to achieve this goal, a framework was proposed, which supported intelligent compression of files used within a Web Service. The proposed framework provided a set of guidelines that facilitate the quick development of a system. A proof-of-concept prototype was developed, based on these guidelines and the framework design principles. The prototype provided practical evidence of the effectiveness of implementing a system based on the proposed framework. An analytical evaluation was conducted to determine the effectiveness of the prototype within the Mobile SOA environment. A performance evaluation was conducted to determine efficiency it provides. Additionally, the performance evaluation highlighted the decrease in file transfer time, as well as the significant reduction in transfer costs. The analytical and performance evaluations demonstrated that the prototype optimises the effectiveness and efficiency of Mobile SOA. The framework could, thus, be used to facilitate efficient file transfer between a Server and (Mobile) Client.

- Description: While career development is viewed as a lifelong process, there are numerous limitations regarding existing career theories and research pertaining to the adolescent population. Further, insufficient longitudinal research represents one of the major obstacles for a more holistic understanding of career development across the lifespan. Thus, the present longitudinal project of which the current study forms a part was initiated to address the lack of research and theory concerning adolescent career development. The larger longitudinal project intended to make information available regarding the occupational aspirations and perceptions of a sample of South African children and adolescents, from early childhood into their adolescent years. The current study investigates the occupational aspiration development of 15 to 16 year old South African adolescents. It is argued that the South African knowledge base on career development behaviour still requires extensive development, especially with regards to adolescent career development. The current longitudinal study aimed to explore and describe possible developments and changes over a two year period in the interest typology, occupational status level and occupational gender stereotypes of the 43 adolescents. Additionally, the study aimed to explore and describe the adolescents' reflections on their own occupational aspiration development. The findings of this study will provide necessary baseline information on the development of South African adolescents' occupational aspirations and will offer valuable recommendations for the future development of adolescent career education programmes. Adolescent and career development theories were used to provide a context for the current study. Semi-structured interviews and biographical questionnaires were utilized to record verbal data which was transposed into nominal data for analysis. Thus, the current study was quantitative in nature. The semi-structured interview comprised four general aspects that included: the adolescents' occupational aspirations, the number of occupations they knew about, how much they knew about the expressed occupations, and the extent to which they held gender stereotypes concerning fourteen different occupations. The data gained was coded according to Holland's (1985) classification system of interest typologies. Also, the adolescents' occupational aspirations were coded according to their status levels. The coded data was subsequently analysed using both descriptive statistics in the form of frequency counts and percentages as well as inferential statistics in the form of chi-square analysis. Content analysis was also conducted on the adolescents' reflections on their own career development as a means to extract themes. The results indicated that adolescence was an important phase of career development and the findings supported adolescent and career development theories. The results of the study also indicated that the majority of adolescents aspired to Investigative type occupations across both years of the study and most adolescents consistently aspired to high status occupations. In addition, adolescents do not appear to gender stereotype in terms of occupations. Lastly, it was found that most adolescents could reflect on their career development, predominantly attributing changes in their occupational aspirations to changes in their interests. The present study has made available important information regarding the occupational aspiration development of a group of South African adolescents, which can be utilized in further research and as a foundation on which to develop career education programmes.

- Description: While career development is viewed as a lifelong process, there are numerous limitations regarding existing career theories and research pertaining to the adolescent population. Further, insufficient longitudinal research represents one of the major obstacles for a more holistic understanding of career development across the lifespan. Thus, the present longitudinal project of which the current study forms a part was initiated to address the lack of research and theory concerning adolescent career development. The larger longitudinal project intended to make information available regarding the occupational aspirations and perceptions of a sample of South African children and adolescents, from early childhood into their adolescent years. The current study investigates the occupational aspiration development of 15 to 16 year old South African adolescents. It is argued that the South African knowledge base on career development behaviour still requires extensive development, especially with regards to adolescent career development. The current longitudinal study aimed to explore and describe possible developments and changes over a two year period in the interest typology, occupational status level and occupational gender stereotypes of the 43 adolescents. Additionally, the study aimed to explore and describe the adolescents' reflections on their own occupational aspiration development. The findings of this study will provide necessary baseline information on the development of South African adolescents' occupational aspirations and will offer valuable recommendations for the future development of adolescent career education programmes. Adolescent and career development theories were used to provide a context for the current study. Semi-structured interviews and biographical questionnaires were utilized to record verbal data which was transposed into nominal data for analysis. Thus, the current study was quantitative in nature. The semi-structured interview comprised four general aspects that included: the adolescents' occupational aspirations, the number of occupations they knew about, how much they knew about the expressed occupations, and the extent to which they held gender stereotypes concerning fourteen different occupations. The data gained was coded according to Holland's (1985) classification system of interest typologies. Also, the adolescents' occupational aspirations were coded according to their status levels. The coded data was subsequently analysed using both descriptive statistics in the form of frequency counts and percentages as well as inferential statistics in the form of chi-square analysis. Content analysis was also conducted on the adolescents' reflections on their own career development as a means to extract themes. The results indicated that adolescence was an important phase of career development and the findings supported adolescent and career development theories. The results of the study also indicated that the majority of adolescents aspired to Investigative type occupations across both years of the study and most adolescents consistently aspired to high status occupations. In addition, adolescents do not appear to gender stereotype in terms of occupations. Lastly, it was found that most adolescents could reflect on their career development, predominantly attributing changes in their occupational aspirations to changes in their interests. The present study has made available important information regarding the occupational aspiration development of a group of South African adolescents, which can be utilized in further research and as a foundation on which to develop career education programmes.

- Description: Society’s reliance on Information Technology (IT) has increased tremendously in the last few decades. Unfortunately, the growth of the IT sector has occurred at the expense of the environment. The adverse environmental impact of IT operations is partly due to the production and disposal of IT equipment, which can result in harmful pollution and toxic materials being released into the environment. Furthermore, IT equipment consumes large amounts of electricity, and this results in significant amounts of carbon dioxide (CO2) being released into the atmosphere. Since CO2 is classified as a greenhouse gas, it contributes to the phenomenon of climate change. Organisations are socially and ethically required to minimise the environmental impact of their IT operations. However, in addition to fulfilling their responsibility towards environmental sustainability, organisations can gain a competitive advantage through adopting green IT practices. In order to reap the benefits of green IT and to fulfil their social and ethical responsibilities, organisations need to formulate and implement a comprehensive green IT strategy. When formulating strategic decisions, the use of a clear decision process enhances the effectiveness of such decisions. As a result, top IT management require a model or framework which could guide their thinking and allow for a clear decision process when formulating green IT strategy. However, after an extensive search of the literature had been conducted, a research gap was identified for the definition of a model which deals specifically with the formulation and execution of green IT strategy. As a result, this treatise sets out to answer the question of what organisations should consider when formulating and implementing green IT strategy. To answer the research question, the treatise defines a model for green IT strategy. The model was defined by conducting a content analysis of the literature on green IT. The content-analysis ABSTRACT iii research technique was utilised to identify the underlying concepts within the literature related to green IT strategy formulation and execution. The resulting model indicates that green IT strategy formulation requires holistic thinking, since several forces affect green IT strategy. As a result, these forces should be considered when a green IT strategy is to be formulated. However, even if a strategy is formulated by considering all the forces at play, it is of little use if it is not implemented effectively. The model indicates that green IT strategy should be implemented though a series of practices. These practices are not limited to IT practices alone, but include, in addition, several business practices. This indicates that green IT adoption extends far beyond the mere implementation of green technology.

- Description: The Information and Communications Technology (ICT) skills shortage is of national and international concern. Modern business practices require the implementation of new technologies supported by a workforce with current and diversified ICT skill-sets. Acquiring suitable ICT skills has become a difficult task and employers are seeing government intervention at all levels. The school system in South Africa is under increased pressure and is faced with continuously declining matriculation pass rates, specifically in subjects such as science and mathematics. Schools are experiencing a decline in the number of scholars (learners) enrolling for the Information Technology (IT) school curriculum. The IT curriculum at school level is being criticised; under-prepared teachers are blamed and lack of suitable facilities highlighted. Surveys conducted amongst grade 9 and grade 12 scholars in the Eastern Cape have shown that scholars are not considering careers in ICT. Teachers, career/guidance counsellors and parents contribute to scholars' career decisions and are not encouraging scholars to pursue careers in ICT. Tertiary institutions in South Africa and internationally, are experiencing a decline in student enrolments and in pass and throughput rates. Industry is holding tertiary institutions responsible for not providing the “correct” ICT graduate skill-sets and passing an insufficient number of quality ICT graduates desperately required by industry. The accreditation of computing degree programs, such as Computer Science (CS), Information Systems (IS) and Information Technology (IT), collectively referred to as CIT, offered by tertiary institutions is becoming an international requirement. The ICT industry is constantly changing and new job requirements and new career opportunities are frequently introduced. Graduates entering the ICT industry should have acquired knowledge about ICT career tracks in order to specialise and choose a suitable career path. Tertiary CIT degree programs should further be linked to specific career tracks and provide a multi-disciplined education to graduates. ii ICT graduates working in industry utilise skills obtained in under-graduate and post-graduate CIT degree programs. The ICT graduates have also obtained valuable skills working in industry, including business skills and soft skills. ICT skill surveys have identified the graduate skills gap, indicating ICT skills industry requires from graduates completing tertiary level qualifications. ICT graduates working in industry, for example indicated that programming in some cases is over-emphasised at school and tertiary level and that soft skills are ignored by tertiary institutions. An ICT Graduate Skills Classifications Framework is developed to address the graduate ICT skills gap and highlight important business skills, soft skills, technical skills and programming skills required by industry. In this thesis, an Industry ICT Value Chain Model is further developed that suggests a holistic approach to the problems experienced at all levels of ICT skills development, including government, industry, tertiary education institutions and at school level. Results from a number of research surveys conducted along the proposed Industry ICT Skills Value Chain Model indicated that problems exist at all stages in the value chain and that the problems can only be addressed involving government, industry and tertiary institutions collectively. A number of interventions is required and the support from industry is essential in achieving overall success in addressing the ICT skills shortage in South Africa. A proposed Industry ICT Skills Value Chain Model that can be utilised to address the ICT skills shortage in South Africa is presented.

- Description: The global rise in divorce since the 1960s has brought into question the idealised view of the nuclear family which has for centuries been awarded special status in western societies and has been regarded as the primary social institution. According to contemporary research parental divorce has become a reality for every one in six children in South Africa. Until recently, little consideration had been given to how divorce affects black South African families, as it was considered to be an occurrence which only took place in white, mainly middle-class, families. The proportion of black South African couples divorcing has been increasing over the past decade, and in 2008 was said to contribute to 35% of all divorce in South Africa. Most research to date on the children of divorce has focused on young white children and adolescents and is largely concerned with those who have found parental divorce particularly difficult, and are manifesting adjustment and other behavioural problems. The research which has been done on the effects of parental divorce on young adults focuses mainly on clinical studies with middle-class families based either in the United States or in the United Kingdom. This research, using an experience-centred, life-story narrative approach, explores the stories which young black South African adult women between the ages of 18 and 25 tell, to give account to the ways in which recent parental divorce has affected their lives, views on family life, and what it has meant to them. The use of an experience-centred, life-story narrative approach allows for a process of rupture, acceptance and re-storying to be accounted for, as the participant’s narrative shifts from past, to present and the future. Five young black women from a South African university each participated in two narratively sequenced semi-structured interviews based on McAdams’ personal narratives protocol, which includes six core themes, namely: Key Events, Significant People, Stresses and Problems, Personal Meanings and Life-Lessons, Future Script, and Life Theme. Crossley’s narrative analysis was then used to identify emergent themes and images in each individual narrative, after which they were woven together into a coherent story linked to previous literature. This study found that divorce involves a highly complex transition and reconfiguration process perhaps not fully accounted for in the existing idea and images associated with it. Despite being young adult women who had moved away from home and were engaged in their own lives, it became apparent that parental divorce was still a difficult and complicated experience, but that it is possible to tell both pessimistic and optimistic stories of parental divorce and its consequences.

- Description: This thesis addresses software design within the field of Information and Communications Technology for Development (ICTD). Specifically, it makes a case for the design and development of software which is custom-made for the context of marginalised rural areas (MRAs). One of the main aims of any ICTD project is sustainability and such sustainability is particularly difficult in MRAs because of the high costs of projects located there. Most literature on ICTD projects focuses on other factors, such as management, regulations, social and community issues when discussing this issue. Technical matters are often down-played or ignored entirely. This thesis argues that MRAs exhibit unique technical characteristics and that by understanding these characteristics, one can possibly design more cost-effective software. One specific characteristic is described and addressed in this thesis – a characteristic we describe here for the first time and call a network island. Further analysis of the literature generates a picture of a distributed network of access nodes (DANs) within such network islands, which are connected by high speed networks and are able to share resources and stimulate usage of technology by offering a wide range of services. This thesis attempts to design a fitting middleware platform for such a context, which would achieve the following aims: i) allow software developers to create solutions for the context more efficiently (correctly, rapidly); ii) stimulate product managers and business owners to create innovative software products more easily (cost-effectively). A given in the context of this thesis is that the software should use free/libre open source software (FLOSS) – good arguments do also exist for the use of FLOSS. A review of useful FLOSS frameworks is undertaken and several of these are examined in an applied part of the thesis, to see how useful they may be. They form the basis for a walking skeleton implementation of the proposed middleware. The Spring framework is the basis for experiments, along with Spring-Webservices, JMX and PHP 5’s web service capabilities. This thesis builds on three years of work at the Siyakhula Living Lab (SLL), an experimental testbed in a MRA in the Mbashe district of the Eastern Cape of South Africa. Several existing products are deployed at the SLL in the fields of eCommerce, eGovernment and eLearning. Requirements specifications are engineered from a variety of sources, including interviews, mailing lists, the author’s experience as a supervisor at the SLL, and a review of the existing SLL products. Future products are also investigated, as the thesis considers current trends in ICTD. Use cases are also derived and listed. Most of the use cases are concerned with management functions of DANs that can be automated, so that operators of DANs can focus on their core business and not on technology. Using the UML Components methodology, the thesis then proceeds to design a middleware component architecture that is derived from the requirements specification. The process proceeds step-by-step, so that the reader can follow how business rules, operations and interfaces are derived from the use cases. Ultimately, the business rules, interfaces and operations are related to business logic, system interfaces and operations that are situated in specific components. The components in turn are derived from the business information model, that is derived from the business concepts that were initially used to describe the context for the requirements engineering. In this way, a logical method for software design is applied to the problem domain to methodically derive a software design for a middleware solution. The thesis tests the design by considering possible weaknesses in the design. The network aspect is tested by interpolating from formal assumptions about the nature of the context. The data access layer is also identified as a possible bottleneck. We suggest the use of fast indexing methods instead of relational databases to maintain flexibility and efficiency of the data layer. Lessons learned from the exercise are discussed, within the context of the author’s experience in software development teams, as well as in ICTD projects. This synthesis of information leads to warnings about the psychology of middleware development. We note that the ICTD domain is a particularly difficult one with regards to software development as business requirements are not usually clearly formulated and developers do not have the requisite domain knowledge. In conclusion, the core arguments of the thesis are recounted in a bullet form, to lay bare the reasoning behind this work. Novel aspects of the work are also highlighted. They include the description of a network island, and aspects of the DAN middleware requirements engineering and design. Future steps for work based on this thesis are mapped out and open problems relating to this research are touched upon.

- Description: Digital audio networks are becoming the preferred solution for the interconnection of professional audio devices. Prominent amongst their advantages are: reduced noise interference, signal multiplexing, and a reduction in the number of cables connecting networked devices. In the context of professional audio, digital networks have been used to connect devices including: mixers, effects units, preamplifiers, breakout boxes, computers, monitoring controllers, and synthesizers. Such networks are governed by protocols that define the connection management rocedures, and device synchronization processes of devices that conform to the protocols. A wide range of digital audio network control protocols exist, each defining specific hardware requirements of devices that conform to them. Device parameter control is achieved by sending a protocol message that indicates the target parameter, and the action that should be performed on the parameter. Typically, a device will conform to only one protocol. By implication, only devices that conform to a specific protocol can communicate with each other, and only a controller that conforms to the protocol can control such devices. This results in the isolation of devices that conform to disparate protocols, since devices of different protocols cannot communicate with each other. This is currently a challenge in the professional music industry, particularly where digital networks are used for audio device control. This investigation seeks to resolve the issue of interoperability between professional audio devices that conform to different digital audio network protocols. This thesis proposes the use of a proxy that allows for the translation of protocol messages, as a solution to the interoperability problem. The proxy abstracts devices of one protocol in terms of another, hence allowing all the networked devices to appear as conforming to the same protocol. The proxy receives messages on behalf of the abstracted device, and then fulfills them in accordance with the protocol that the abstracted device conforms to. Any number of protocol devices can be abstracted within such a proxy. This has the added advantage of allowing a common controller to control devices that conform to the different protocols.

- Description: Digital audio networks are becoming the preferred solution for the interconnection of professional audio devices. Prominent amongst their advantages are: reduced noise interference, signal multiplexing, and a reduction in the number of cables connecting networked devices. In the context of professional audio, digital networks have been used to connect devices including: mixers, effects units, preamplifiers, breakout boxes, computers, monitoring controllers, and synthesizers. Such networks are governed by protocols that define the connection management rocedures, and device synchronization processes of devices that conform to the protocols. A wide range of digital audio network control protocols exist, each defining specific hardware requirements of devices that conform to them. Device parameter control is achieved by sending a protocol message that indicates the target parameter, and the action that should be performed on the parameter. Typically, a device will conform to only one protocol. By implication, only devices that conform to a specific protocol can communicate with each other, and only a controller that conforms to the protocol can control such devices. This results in the isolation of devices that conform to disparate protocols, since devices of different protocols cannot communicate with each other. This is currently a challenge in the professional music industry, particularly where digital networks are used for audio device control. This investigation seeks to resolve the issue of interoperability between professional audio devices that conform to different digital audio network protocols. This thesis proposes the use of a proxy that allows for the translation of protocol messages, as a solution to the interoperability problem. The proxy abstracts devices of one protocol in terms of another, hence allowing all the networked devices to appear as conforming to the same protocol. The proxy receives messages on behalf of the abstracted device, and then fulfills them in accordance with the protocol that the abstracted device conforms to. Any number of protocol devices can be abstracted within such a proxy. This has the added advantage of allowing a common controller to control devices that conform to the different protocols.

- Description: Psychobiographies use psychological theory as a paradigm within which to re-awaken an individual’s life story. The psychobiographical approach historically tended to be neglected within the South African context. The aim of the current study was to explore and describe the life of Ralph John Rabie through the use of psychobiography. Ralph John Rabie (1960 – 2002) was a South African Afrikaans singer-songwriter, journalist and playwright, also known as Johannes Kerkorrel. He challenged the cultural system and the government and was arguably the most prominent member of the Alternative Afrikaans Movement until his suicide on 12 November 2002. To some he betrayed the identity of post-apartheid Afrikanerdom and to others he became an icon in the homosexual community. No existing literature to date has adopted a psychological stance on this controversial South African figure. His own writings and published material by others were utilized to illuminate his life and its many dimensions. Richard C. Schwartz’s Internal Family Systems Model (1995) was used to analyze the multiplicity and inner workings of Rabie’s personality. The influence of external systems is also discussed. The data collection and analysis were conducted according to Yin’s (1994) analytic generalization, which consists of using theoretical guidelines as a framework to select relevant data and develop a matrix as a descriptive framework for organizing and integrating the data. Alexander’s (1988) nine proposed guidelines assisted in the process of data analysis, together with the Internal Family Systems Model (1995). The findings of the study indicate that subpersonalities in different roles could be identified in Rabie’s life as described by Schwartz (1995). The different subpersonalities interacted with each other and assumed roles to protect Rabie. The findings of the study also indicated that these subpersonalities used stories to obtain power and influence within Rabie’s personality structure. The subpersonalities were successful in making Rabie influential and famous within the Afrikaans music industry and they helped Rabie change rigid Afrikaans cultural beliefs that were present within the Apartheid system. The findings further indicate how important it is for subpersonalities to work together and how a fragmented system is difficult to contain.

- Description: While the value of psychobiographical research continues to be debated, interest in this area is growing on an international basis. From the ever increasing number of studies being conducted in connection with academic institutions in South Africa, the vitality and worthiness of studying lives lived in conjunction with the applicability of psychological theories is showing itself to be an exciting world in which to participate. This particular research study aimed to explore and describe the developmental life stages of Paul Jackson Pollock. Pollock was, and continues to be, a controversial figure in the art world as there is much debate over the artistic merit of his paintings. Unconventional in all that he did, Pollock challenged the art world by moving beyond paintbrush and easel to throwing paint across canvasses laid out on the floor. Around these emerging artworks he would move in a staccato dance, mesmerising those present by the way he made art immediate using his entire body to create the abstract image. Pollock is credited with being the pioneer of abstract expressionism in the United States, and to date his paintings are credited as being among the most expensive ever sold. He struggled with alcoholism and emotional instability throughout his teens and adult life. His alcoholism eventually caused his death at the age of 44 when, while heavily intoxicated, he drove his car into a tree a few metres from his home. No known literature has adopted an exclusively psychological stance when studying the life of this individual. The progression of Pollock’s lifespan development was filtered through Erikson’s (1950) theory of psychosocial stages. Erikson’s (1950) theory takes a holistic, biopsychosocial approach to human development, with an emphasis on ego development. Data was collected from both primary and secondary sources to enhance internal validity, and the data was then analysed according to Miles and Huberman’s 1994 general approach, taking Alexander’s (1990) nine identifiers of salience into necessary consideration. Using this framework, it was found that Jackson Pollock’s development coincides with Erikson’s theoretical psychosocial stage constructs, lending weight to Erikson’s theory. While Pollock’s life paralleled Erikson’s (1950) theory in many ways, the theory failed to provide enough definition with regards to constructs and intrapsychic processes. However, this study has also shown that there is great value and relevance to be found in Erikson’s (1950) theory, even though it was developed over fifty years ago.

- Description: Organisations or individuals that lend money (banks and micro lenders) or that sell goods on credit (retailers) are classified as credit providers. The debtor enters into a contractual agreement with a credit provider, or creditor, with the obligation to repay the loan amount, fees and interest according to a predetermined schedule. The contractual agreement, also known as a credit agreement, is as a general rule very complex. Legislation protecting debtors in various ways is an international phenomenon. In South Africa, the National Credit Act, Act 34 of 2005 (NCA) was enacted in 2005. The NCA changed the playing field for credit providers participating in the South African consumer credit market to a great extent. Consumer lending is the sleeping giant of the financial sector. The key to successfully unlock this enormous market is the credit provider's ability to accurately assess the creditworthiness of a potential customer during the customer acquisition phase. The creditworthiness of the customer is related to the risk of default, i.e. a debtor's non-payment of debt in terms of the credit agreement. The risk of default is also known as credit risk. Real People Investment Holdings (Pty) Ltd (RPIH) classifies credit risk as the single largest risk the Group is exposed to. They recognise that the intelligent and responsible management of credit risk makes it the Group's largest profit driver. Credit risk scorecards are excellent decision aids during the customer acquisition phase. The characteristics and behaviour of merchants submitting credit applications to RPIH for assessment have a definite impact on the credit risk of the Group. The merchant plays a pivotal role in the debtor-creditor-supplier business model. The merchant influences the customer's sales experience and subsequent level of satisfaction with the transaction. A satisfied customer constitutes a lower level of credit risk for the creditor, in this case RPIH. The research is conducted with a positivistic paradigm. The cross-sectional study approach is used. The merchant is the unit of analysis. A sample of 77 merchants is selected from the population of 244 merchants who submitted credit applications to RPIH during the observation period. Questionnaires are used as the data collection method in this research project. The predictive ability of fourteen merchant related characteristics are demonstrated through this empirical study.

- Description: Service-oriented architectures (SOA) are being adopted by organisations in order to integrate disparate computational assets. A major hurdle they face is the decision on how to integrate the UI in an SOA. In addition, technological advances have allowed complex applications and complex user interfaces (UIs) to be realised and the increase in accessibility to computers enables a diverse population of users with different characteristics, preferences and needs to use these complex computer applications. Adaptive user interfaces (AUIs) have been proposed as a solution to cater for the differences in user traits by adapting the UI to meet the diverse needs of users. AUIs have, however, traditionally been developed using client/server architectures This research, therefore, set out to investigate how to develop an AUI using a service-oriented architecture (SOA). In order to successfully achieve the goal of this research, literature concerning SOAs was investigated to gain an understanding of SOAs. A literature review of AUIs was also undertaken to gain an understanding of AUIs. A model-based approach was used to develop a model for UI adaptation using knowledge gained in the literature reviews. The model generates different UIs depending on various users‘ inferred level of expertise. The model describes the interaction between AUI services that use design-time documents and run-time user-interaction to adapt the UI. A prototype of the model was implemented and evaluated using an evolution strategy devised to assess different aspects of the research. The evaluation strategy proved the following: The service components of the prototype adhere to SOA design principles; The implementation was effective based on software engineering metrics; and, The implementation was usable and did not negatively affect the performance of users. The successful implementation of the prototype provides evidence that the design of AUIs using SOA is feasible. This dissertation therefore makes a contribution to the development of AUIs using SOAs. The model could be used to provide UI adaptation for business software applications.

- Description: This study reports on a social-realist analysis of collaborative curriculum development in a journalism and media studies (JMS) department at a South African university. Archer's social-realist meta-theoretical framework is used to theorise about mechanisms that influence collaborative curriculum development within the context of the JMS Department. The thesis examines the cultural, structural and agential conditions that influenced the process of developing a JMS curriculum that aimed to integrate theory and practice. Bernstein's theories of knowledge recontextualisation and disciplinary knowledge structures are used in the analysis. Bernstein argues that knowledge recontextualisation constitutes a site of struggle. This thesis is an examination of the "struggles" for the epistemic-pedagogic device (Maton's elaboration of Bernstein's epistemic device) during the recontextualisation process that aimed to integrate media studies (MS) and media production (MP) in the JMS curriculum. Traditionally academic work has been an individual endeavour. However, given the growing need to work in disciplinary and inter-disciplinary teams, it is imperative to develop knowledge of the mechanisms that influence such practices. This thesis is a contribution to knowledge of collaborative processes at the level of an academic department in a university. It contributes to knowledge of cultural, structural and agential mechanisms that enable or constrain collaborative curriculum development within a particular kind of context. In addition it contributes to knowledge of the nature of leadership that may be necessary to facilitate productive collaborative relationships and practices in such a context. The curriculum development project reported on in this thesis was initiated in 2003; however, data collection for the study was conducted in 2006 when the curriculum for the fourth year (JMS 4) of the Bachelor of Journalism degree was developed. Since the JMS course prepares students to work as journalists or media workers it is necessary for the curriculum and pedagogy to be oriented both towards the academy and towards the media industries. The aim of the JMS degree is to develop students who will be critically reflexive journalists or media workers. As such the course is both theoretical (MS) and practical (MP). One of the findings of this research project is that the integration of MS and MP is a complex project given that the knowledge of the two disciplines is structured differently. MS is concept-dependent and some aspects of it can be applied to journalism and media practice, while MP is practical and thus context-dependent, though underpinned by theory. A further finding is that both the collaborative work and the integration project required different identity shifts from the lecturers in the JMS Department. Some were more able to make the shifts than others. The thesis shows that the knowledge recontextualisation struggles in the curriculum development processes of the Department of JMS centred around, inter alia, the setting of boundaries between the department and the media and journalism industries, between MS and MP and between MS theory and journalism theory. In addition, existing boundaries between MS and MP lecturers had to be traversed. These boundaries were circumscribed by, amongst other things, unequal power relations emanating from the higher status traditionally accorded to theoretical knowledge by universities, the tensions around the nature of journalism education and training and the differential properties and powers of the various lecturers within the department. The existence of a strong regulative discourse was found to be an important unifying mechanism in a tension-ridden context.

- Description: Several Schiff base ligands, N, N‟-(aryl)benzyaldiimine ligands (R-BEN); N, N‟-(aryl)benzyaldiamine dihydrochloride ligands (R-BENH•2HCl); N, N‟-(aryl)benzyaldiamine ligands (R-BENH); N, N‟-bis(cinnamaldiimine) ligands (R-CA2EN) were synthesized for the investigation of the electronic effect of the substituents at para-position of the Schiff base ligands and their copper complexes. The synthesis of Schiff bases was carried out by reacting a series of para-substituted benzyaldehyde, and para-substituted cinnamaldehyde with ethylenediamine. The imine group of Schiff bases, N, N‟-(aryl)benzyaldiimine ligands and N, N‟-bis(cinnamaldiimine)ligands were reduced to corresponding amines with sodium borohydride in methanol These ligands, N, N‟-(aryl)benzyaldiamine ligands (H-BENH), N, N‟-bis(cinnamaldiimine)ligands (CA2EN) were reacted with copper(II) dihalide and copper(I) monohalide ions respectively to form complexes. The ligands and their complexes were analysed using elemental analyses, FT-IR spectroscopy (mid-IR), UV/vis in aprotic and protic solvents,while mass spectrometry, 1H-NMR and 13C-NMR were used to further analyse the ligands. By using substituent parameters, both the single and dual substituent parameters with the spectroscopic data obtained from the spectroscopic techiques mentioned above, it was hoped to monitor and determine whether the electronic effects (resonance or inductive effcets) was predominantly within the Schiff base ligands and copper complexes. The NMR studies with dual substituent parameters suggest that the effects of the substituents are transimitted through the ligands, via resonance effects and that the phenyl group is nonplanar with the azomethine in N, N‟-(aryl)benzyaldiimine ligands. The presence of an extra double bond in Schiff base {(N, N‟-bis(cinnamaldiimine) ligand)} altered the electron density. The UV/vis studies showed that the symmetry of the N, N‟-bis(4-R-benzyl)-1, 2-diaminoethanedihalidecopper(II) complexes were predominantly tetrahedral for both chloro and bromo complexes. The correlation studies from mid-infrared were beneficial in monitoring the effect experienced by N, N‟-(aryl)benzaldiimine ligands, the studies suggest that the inductive effect is more pronounced at the C=N.

- Description: Several Schiff base ligands, N, N‟-(aryl)benzyaldiimine ligands (R-BEN); N, N‟-(aryl)benzyaldiamine dihydrochloride ligands (R-BENH•2HCl); N, N‟-(aryl)benzyaldiamine ligands (R-BENH); N, N‟-bis(cinnamaldiimine) ligands (R-CA2EN) were synthesized for the investigation of the electronic effect of the substituents at para-position of the Schiff base ligands and their copper complexes. The synthesis of Schiff bases was carried out by reacting a series of para-substituted benzyaldehyde, and para-substituted cinnamaldehyde with ethylenediamine. The imine group of Schiff bases, N, N‟-(aryl)benzyaldiimine ligands and N, N‟-bis(cinnamaldiimine)ligands were reduced to corresponding amines with sodium borohydride in methanol These ligands, N, N‟-(aryl)benzyaldiamine ligands (H-BENH), N, N‟-bis(cinnamaldiimine)ligands (CA2EN) were reacted with copper(II) dihalide and copper(I) monohalide ions respectively to form complexes. The ligands and their complexes were analysed using elemental analyses, FT-IR spectroscopy (mid-IR), UV/vis in aprotic and protic solvents,while mass spectrometry, 1H-NMR and 13C-NMR were used to further analyse the ligands. By using substituent parameters, both the single and dual substituent parameters with the spectroscopic data obtained from the spectroscopic techiques mentioned above, it was hoped to monitor and determine whether the electronic effects (resonance or inductive effcets) was predominantly within the Schiff base ligands and copper complexes. The NMR studies with dual substituent parameters suggest that the effects of the substituents are transimitted through the ligands, via resonance effects and that the phenyl group is nonplanar with the azomethine in N, N‟-(aryl)benzyaldiimine ligands. The presence of an extra double bond in Schiff base {(N, N‟-bis(cinnamaldiimine) ligand)} altered the electron density. The UV/vis studies showed that the symmetry of the N, N‟-bis(4-R-benzyl)-1, 2-diaminoethanedihalidecopper(II) complexes were predominantly tetrahedral for both chloro and bromo complexes. The correlation studies from mid-infrared were beneficial in monitoring the effect experienced by N, N‟-(aryl)benzaldiimine ligands, the studies suggest that the inductive effect is more pronounced at the C=N.

- Description: The strategy of the organisation and its entrepreneur’s expectations of the organisation should be aligned in order to create an environment in which all entrepreneurs are motivated and work towards common goals. Furthermore, the entrepreneur’s life stages and personal life plans should be synchronised with the needs of the organisation to achieve the goals. As organisations pass through different stages of growth; they require different resources to assist in progression to next stages. As with organisations and their growth phases; entrepreneurs also undergo growth stages in many different areas of their lives. Entrepreneurs being individuals each have their own set of characteristics in terms of personality, leadership style, entrepreneurship type, skills, life stage and career stages. The challenge of an organisation is to create a strategy that best matches the expectations of all the entrepreneurs and members. The resources of the organisation need to be aligned in order to achieve the common strategy. The problem is as to how the organisation makes use of its leaders and entrepreneurs to achieve strategy; and how does it deal with inconsistencies in goals of entrepreneurs and shortfalls of specific skills or resources that it will require to sustain or grow the organisation?

- Description: There has been only limited scholarly analysis of Malawi’s foreign policy since its independence in 1964 with key texts focusing primarily on the early years of the new state. Perhaps due to its relatively small stature – economically, politically and militarily – in the region, very little attention has been paid to the factors informing Malawi’s apparently uncritical foreign policy response to the Zimbabwe crisis since it began in the late 1990s. This thesis addresses this deficit by locating its understanding of Malawi’s contemporary foreign policy towards Zimbabwe in the broader historical and contemporary context of bilateral relations between the two states and the multilateral forum of SADCC and SADC. It is argued that the Malawi’s long-standing quest for socio-economic development has forced it to manoeuvre a pragmatic but sometimes contentious foreign policy path. This was also evident until the end of the Cold War and the concomitant demise of apartheid in South Africa in the early 1990s. Malawi forged deliberate diplomatic and economic relations with the region’s white-ruled Zimbabwe (then Southern Rhodesia) and South Africa in pursuit of its national economic interests while the majority of southern African states collectively sought the liberation of the region by facilitating the independence of Zimbabwe and countering South Africa’s apartheid and regional destabilization policies. In the contemporary era, there has been a convergence of foreign policy ambitions in the region and Malawi now coordinates its regional foreign policy within the framework of SADC, which itself prioritizes the attainment of socio-economic development. However, to understand Malawi’s response to the Zimbabwe crisis only in the context of SADC’s “quiet diplomacy” mediation efforts obscures important historically rooted socioeconomic and political factors that have informed relations between Malawi and Zimbabwe and which cannot, it is argued, be ignored if a holistic understanding of Malawi’s position is to be sought. This study argues that the nature of historical ties between Malawi and Zimbabwe and the role of Malawi’s leaders in driving its long-standing quest for socioeconomic development have not only informed its overall foreign policy behaviour in the region but underpin its contemporary relations with Zimbabwe.
