- Description: Discipline in the government schools in South Africa has deteriorated during the past fifteen years. There are many different reasons for that. The aim of this study was to develop a uniform programme of discipline which can be used for application in all ten schools in the Bitou area. To reach this aim, the following procedures were followed: • A study has been done regarding the supporting role of the Bitou 10 foundation in the designing and management of a uniform discipline program. • A summary of the disciplinary problems in government schools has been given with possible reasons why discipline has deteriorated. • A study has also been made of various programs of discipline which have been used in various countries in the past. Certain aspects of those programmes have been used in this study to compile an effective programme of discipline for all the schools in the Bitou area. • Criteria for a positive discipline program have been put together. This study has been done in the Plettenberg Bay area. This area has ten schools which include primary- and high schools, single medium- and double medium schools, multi-cultural and mono-cultural schools and also some schools which have hostels. This study showed that not all schools in the Bitou area follow the same disciplinary programme. This study also makes recommendations on the possible implementing of such a uniform system of discipline. This study does not only show what the role is of the principal and teachers responsible for discipline, but also indicates the role and task of the parents and the community. Research on the application of discipline can never end because new ideas and methods will always be found to create an ideal programme in order to make the process more effective.

- Description: The focus of this dissertation is a comparative study of Ingrid Winterbach's Die boek van toeval en toeverlaat (2006) [The Book of Happenstance (2008)] and Etienne van Heerden's Asbesmiddag (2007) [Asbestos Afternoon] within an intertextual and socio-political framework. Both novels show strong links to the literary traditions of which they form part through a high degree of intertextuality with literary predecessors (intertexts from Afrikaans and South African English literature, but also classical intertexts emanating from the larger field of world literature). Both texts exhibit an overt metatextual consciousness. The protagonists in each of these novels are portrayed as novelists. One of the main aims of the study is to interrogate the implied ideological perspectives in both novels - the nature and extent of the reflection of the current South African socio-political system. Winterbach and Van Heerden‘s texts may both be read as fictionalised forms of "protest" against the extrinsic South African socio-political order. These forms of protest focus on the inevitable change from one stage/era to the next, the old South Africa to the new, in a quest for artistic (creative writing and literature) and cultural (Afrikaner identity and language) survival. Die boek van toeval en toeverlaat (2006) and Asbesmiddag (2007) contribute to contemporary discourse by offering implied ideological insights into specific socio-political and metatextual phenomena. This is done in fictional guise - through the characters populating the fictional world of the novel, and also through the authors' implied ideological views. Both novels are intensely concerned with language issues, as well as the status of literature as cultural product. On the metatextual level theoretical issues concerning literature are in the focus, such as the precarious position of the novelist (and the academic) in contemporary South African society, and the status of literature and Afrikaans as a minority language. The purpose of this comparative study is to look at the metatextual, ideological and linguistic aspects of the novels through an extensive intertextual study, in order to interrogate and illustrate the socio-political discourse embedded in them.

- Description: Secondary metabolites derived from plants, especially those used by traditional healers, are at the forefront of new drug development in combating diseases such as cancer and diabetes. Garlic is employed in indigenous medicine all over the world for the treatment of a variety of diseases. Dietary garlic has been recognized for its beneficial health effects. In particular, garlic consumption has been correlated with (i) reduction of risk factors for cardiovascular diseases and cancer, (ii) stimulation of immune function, (iii) enhanced detoxification of foreign compounds, (iv) hepatoprotection, (v) antimicrobial effects, (vi) antioxidant effects, and most importantly (vii) its hypoglycemic and anticoagulant properties. Due to these beneficial properties, garlic and its closely related genera which includes Tulbaghia violacea, may be useful as coadjuvant therapy in the treatment of type 2 diabetes and some of its physiological complications. The aim of this study was to determine if T. violacea has antidiabetic and anticoagulant properties. This was performed in vitro using both aqueous and organic extracts of the roots, leaves and bulbs. An organic extract was able to improve glucose-stimulated insulin secretion (GSIS) in INS-1 pancreatic β-cells and glucose uptake in Chang liver cells. The BO extract had no effect on the glucose uptake in 3T3-L1 an adipose cell line and reduced glucose utilisation in C2C12, a skeletal muscle cell line. Some of the properties displayed by T. violacea in this study are consistent with those found in similar studies with garlic extracts. It was observed that the BO extract increased the membrane potential and Glut-2 expression in INS-1 cells cultured at hyperglycemic levels, however, at normoglycemic levels a reduction was observed. The oxygen consumption increased at both glycemic levels due to treatment with the BO extract. Platelets were exposed to the extracts to determine their effects upon platelet aggregation, adhesion and protein secretion. Since the BO extract displayed the highest potential at inhibiting platelet aggregation and adhesion. A rat model was used in ex vivo studies to determine if the extract exhibited the same effect in a physiological model. It was noted that the BO extract exhibited a higher degree of inhibition on platelet aggregation and adhesion than the positive control, aspirin. The BO extract reduced clotting times in the prothrombin time (PT) test, but prolonged the clotting time in the actived partial thromboplastin time (APTT) assay in the ex vivo model; however, it had no affect on these clotting assays in the in vitro model using human blood. The BO extract increased the D-dimer and Fibrinogen-C levels in the in vitro model, but had no effect on the D-dimer concentrations and lowered the Fibrinogen-C levels in the ex vivo model. The active compounds in the extract remain to be elucidated.

- Description: The main purposes of this thesis are to investigate the difference between the written English of deaf children and the written English of hearing children and to make recommendations on how to improve the writing of deaf children. In order to achieve this goal, both quantitative and qualitative research was done. The comparison of the writing of deaf and hearing children relies on quantitative research while the recommendations are based on qualitative analysis. The dissertation is divided into seven chapters. The first chapter discusses the problem, the significance of the research, the purpose of the study, the background to the problem and the theoretical framework. This chapter indicates the prevalence of deafness worldwide and in South Africa and its negative impact on the writing abilities of children. The second chapter provides a literature review on the theory behind reading and writing, with specific emphasis on emergent literacy and its relevance to the language acquisition and print language learning of deaf children. Another aspect of this chapter is the effect of different aspects of deafness on language acquisition and learning. The chapter also highlights the challenges for deaf children in South Africa and debates regarding the language of instruction that should be used to teach deaf children writing/reading, as well as arguments concerning bottom-up, top-down, and interactive approaches to writing. The third chapter provides the overall philosophical framework for the quantitative and qualitative research as well as the methodology used for the qualitative research. This is followed by the results of the quantitative research and a discussion of these results in Chapter 4. The fifth chapter is in the form of a second literature review that contains recommendations for improving the writing of deaf children. Following this, in Chapter 6, is a discussion of some of the theory behind interview interaction, as well as an analysis of how to develop a valid study. The researcher also sets out the interview structure. The seventh chapter contains a discussion of the findings of the interview to see if they confirm the findings in Chapter 5, as well as overall conclusions about assisting deaf children with their writing, a reflection on the study as a whole and suggestions for future research. This study argues that in order for deaf children in South Africa to develop their writing, immediate government assistance is necessary in order to implement countrywide newborn hearing screening, followed by medical and/or language-based ii intervention to minimise the impact of deafness on the language and writing abilities of deaf children. This is an essential foundation from which parents and teachers can build and play a key role in helping their children reach age-appropriate levels of written English.

- Description: Current trends in technology have led to a need for creativity and innovation in the design of contemporary digital products and systems. This has resulted in design thinking and creative design process having a higher profile in digital design practice. In turn, this has impacted computing education, by creating a need for computing students to develop creativity and design thinking skills. Creative design is taught using design studio teaching methods, which require a culture, environment and activities that are different to the teaching methods used in traditional computing education. Some computing academics have implemented courses using aspects of studio teaching methods, but no clear guidelines for a computing academic without creative design experience to fully apply studio teaching methods in courses could be found. The reason for the change in the role of design in the digital domain and how it affected the needs of computing students was investigated and a comparison of typical design studio and computing teaching methods was conducted using a learning systems model adapted for this specific purpose. This led to an identification of areas that required further investigation, or gaps in the knowledge of how to adapt design studio methods for use within a traditional computing education environment. These gaps were used as the basis for identifying a set of research questions for an empirical study. An exploratory case study was conducted at the Nelson Mandela Metropolitan University to answer the research questions. Three computing academics implemented studio teaching methods within three separate modules, following provisional guidelines devised from the preliminary research. Feedback was collected from the lecturers and the students registered for the modules regarding their experiences. It was found that it would be possible for computing academics to implement aspects of a design studio approach within the existing computing environment. An explicit teaching method, termed the computing studio teaching method, was developed from the results of the case study. This teaching method aims to provide computing academics with little or no creative design experience with explicit methods for implementing modified design studio teaching methods in order to promote creativity and design thinking within traditional computing modules. This teaching method will be tested, validated and refined in future research.

- Description: The South African motor industry plays a pivotal role in the economy of South Africa and is a leading indicator in economic change. In general, satisfaction of customer service in the motor industry is steadily improving. However, as research has shown, there is still room for improvement within the industry. Knowing what customers expect is a critical step in delivering good quality service to ensure customer retention in the long-term (Zeithaml, Parasuraman & Berry 1990:62-63). Having a good understanding of the value of forming long-term relationships with customers and their evaluation of the quality of the service provided, cannot be underestimated, as failure to actually ask customers what they think of the service could be detrimental in the long-term. Vehicle manufacturers conduct ongoing research to monitor customer perceptions of the quality of the service provided by their vehicle retailers. The information generated from the research findings can be used by manufacturers to improve levels of service where this appears to be lacking, and deal promptly with any customer complaints. Against this background, how vehicle owners judge the quality of the service provided by a franchised vehicle retailer for a repair and maintenance service, will be crucial to understanding how customers form perceptions of service related firms specifically, and in general, even an entire industry. The primary objective of this study is to assess customer perceptions of service quality with a franchised vehicle retailer following a routine repair and maintenance service. The sample consisted of 3 859 respondents who had their vehicles serviced at a GM South Africa franchised vehicle retailer over a one month period. The empirical results of the study revealed that GM South Africa show general positive results in terms of customer service satisfaction, however, there are some areas where additional attention is required.

- Description: "Mining operations" and "mining" are defined in s 1 of the Income Tax Act (ITA). A concept that is of great significance to this definition is the matter of when a mineral is won and the related question of when does the mining process end and the process of manufacture commences. Case law has not established a definitive point that can be used by the mining taxpayer to determine where the mining process ends for income tax purposes. The Supreme Court of Appeal was presented with the perfect opportunity in the Foskor1 case to clearly define the boundaries between these processes. Unfortunately, the court did not seize this opportunity to provide legal certainty. The significance of the distinction lies in the fact that a mining taxpayer is allowed to claim accelerated capital allowances. The objective of these allowances is to provide tax relief to the mining taxpayer taking the immense risk of investing billions of rands in capital expenditure. The capital expenditure incurred will also result in direct foreign investment. This in turn will result in economic growth and job creation. Currently, there is no legal certainty as to which processes will qualify as mining operations for income tax purposes. This may result in mining taxpayers being hesitant to incur capital expenditure as the risk relating to a project would have increased. The accelerated capital allowances may therefore not serve their intended purpose. The gross domestic product (GDP) contribution from gold mining has been decreasing in the last number of years, but this decrease has to a large extent been offset by an increase in the downstream or beneficiated minerals industry. This industry has also been identified by Government as a growth sector. The downstream or beneficiated mineral industry may not be catered for in the current definition of "mining operations" and "mining" and may therefore not qualify for beneficial tax allowances. It is therefore proposed that the term "won" as used in the definition of "mining operations" and "mining" should be defined in s 1 of the ITA as follows: A mineral is "won" when all the requisite and necessary processes, including, amongst other things, refinement, beneficiation, smelting, separation, have been undertaken to the mineral to render it saleable in an open and general market. This extension will provide legal certainty to a mining taxpayer and will ensure that South Africa obtains direct foreign investment and maximum value for its minerals. This will contribute to economic growth for South Africa's developing economy and result in job creation.

- 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: 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: 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: 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: 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: This study investigates parental involvement in school governance in selected high schools in Zwelitsha, King Williams Town District in the Eastern Cape Province. The research study was conducted in three high schools in Zwelitsha Township. These schools are Nompendulo Senior Secondary, Thembalabantu High School and Xolani Senior Secondary School. Questionnaires were designed and distributed to the principals, educators and parents whose children are learners in these schools. The interview questions were designed and distributed to parents whose children are learners in these selected schools, educators and school principals and members of the school governing body from each school. Respondents were asked about the levels of parental involvement in their schools, parents’ awareness of school governance and the relationship between schools and communities. However, the objectives of the study were to: Assess parental involvement in school governance in selected high schools in Zwelitsha, King Williams Town District in the Province of the Eastern Cape; To determine the nature and extent of parental participation in school academic activities; To examine the role of parents in the school governing body; To determine measures that can be taken to encourage the participation of parents in school governance These objectives have been achieved by providing empirical evidences which shows that the levels of parental involvement in the previously disadvantaged high schools are very low. This is related to the parents’ level of education. Parents who are literate are more involved than those are illiterate. This research also reveals that high v. levels of working parents contributes to the low levels of parental involvement in school governance. Most parents in this area know nothing about school governance and those that are aware are not keen to be involved. The class structure of the society has an influence in the participation of parents in school governance. Parents’ meetings that are held on Sunday afternoon are a challenge to parents that come from the villages outside Zwelitsha because of the scarcity of transport on this day. and these situations discourage them from being actively involved in their children’s education. The study provides the factors that cause non-involvement of parents in school governance. Subsequently, the following strategies for participation of parents in school governance were given: Capacitating of parents Establishment of teacher-parent collegiality Recognition of cultural capital Establishment of parent organisations Utilisation of non-governmental organisations Establishment of centres of learning. This study also indicates the following strategies that may assist to enhance the parental involvement in school governance: Parents engagement and empowerment Co-operation between schools and parents Collaboration with other community, private and other public institutions Invitation of complaints and welcoming of criticism. In conclusion, the findings provide clear indication that the participation of parents in school governance is low. Recommendations that could assist the schools to encourage and to enhance parents to participate in school governance are given.

- Description: Rural-urban migration appears to be an ongoing process in South Africa. This is attributed to various reasons. In itself, the process contributes towards an ongoing demand for services such as housing, water, sanitation and transportation systems. Rural – urban migration plays a key role in urbanization. The living conditions in rural areas appear to be the main contributing factors towards rural-urban migration. This indicates that the challenges facing rural communities include the creation of conducive environments within those communities. Hence, the issue of rural-urban migration should be addressed from the spatial and socio – economic perspectives. In an attempt to address human settlements needs, South Africa has a policy framework which supports the right to housing as it has been accorded to South African citizens by their Constitution. The objective is to ensure that there is adequate housing for South Africans. This study investigated and analysed the relationship between rural-urban migration and housing delivery in Clermont Township in the Province of KwaZulu-Natal. The participants included the residents of Clermont Township and the representatives of the eThekwini Municipality. Among others, the study found that rural-urban migration is an ongoing process which affects housing delivery in urban areas. As a result it continues to make the objective of ensuring that there is adequate housing for South Africans unattainable. Hence, attention should be paid to the effects of rural-urban migration in housing delivery.
