- Description: Research suggests that there is a relationship between religion and business ethics. When looking at the South African society and the statistics that says that 80 percent of the population is Christian but on the other hand we are confronted within this country with increasing incidents of corruption in private companies as well as in public services. Why would that be the case? This study seeks to understand if Christianity or the local church really makes an impact on the lives of its members. The research starts of by looking at behaviour in general and what constitute to good ethical decision-making. In the study on Christian ethics it becomes clear that there is a strong appeal in the Bible on ethical behaviour. The Bible goes as far as to claim that, when in a relationship with the Lord, the followers will show His character in the way they live at home and the way they behave and make ethical decisions at the workplace. This study used focus groups to research the role of the local church in changing behaviour. The study finds that Christianity per se does not change the behaviour of church members. The church members‘ definition of the church largely determines the impact the church will have on their lives. In the study on the Christian ethics it was clear that ethics were seen as something that was formed in communities and not by rules or regulations. It was not a case of people telling others what to do and what not. It was more a case of mentors that helped others to live differently in community with others. The study finds that when the local church is build on relationships and if there is a strong sense of community, the church has a huge impact on the lives of its members. This suggests that the local church should be more focused on strong and intimate relationships and not so much on the church as organisation or institute. This is also important for the businesses that will employ these members because they will make better ethical decisions.

- Description: This quantitative exploratory-descriptive study investigated the value of human figure drawing (HFD) tests for developmental testing in the South African context. Due to their characteristics such tests may be particularly suitable to screen for developmental delays in the local South African context. The objectives of the research were to explore and describe the standardized HFD scores and Griffiths Mental Development Scales – Extended Revised (GMDS-ER) general quotients (GQ) of the sample; to investigate whether a relationship exists between the standardized HFD scores and GQs; and to investigate the strength and directionality of this relationship if it was found to exist in the sample. Relevant literature was discussed and an integration of key constructs was provided. The research sample consisted of 30 GMDS-ER protocols collected at a University Psychology Clinic in the Nelson Mandela metropol, Eastern Cape, South Africa. The HFDs of the Draw-a-person items of the GMDS-ER protocols were scored according to the scoring criteria of the Draw-a-Person Intellectual Ability Test for Children, Adolescents, and Adults (DAP: IQ). Key findings included the following: a statistically significant large positive correlation indicative of a marked relationship existed between standardized HFD scores and GQs. The DAP: IQ might provide a better indication of mental development than intellectual ability. A statistically significant medium positive correlation indicative of a small but definite relationship existed between chronological age and HFD raw scores. In conclusion, the findings suggest that HFDs follow a developmental progression and that HFD tests may be useful in developmental testing.

- Description: The electrolysis of water was evaluated as a potentially efficient, as a low cost means of hydrogen production. The theoretical energy, voltage, current, and energy efficiencies of water electrolysis were considered by using various catalyst materials used in the fabrication of membrane electrode assemblies used in low temperature water electrolysis systems. Traditionally, iridium based catalysts have shown to be the most suitable material for its use on electrocatalysis of water to form hydrogen. This study showed that a combination of various elements as a binary and or ternary mixture in the base catalyst that was applied to the anode and cathode by using the Adam’s method had shown to give comparatively good results to that of using iridium oxide on its own. These catalysts were characterized by cyclic voltammetry, at different temperatures (30oC-80oC) with a range of catalyst loading of 0.2-0.5 mg.cm-2 noble metals. The study showed that the Ir40Co40 mixture as an anode catalyst was found to show highest hydrogen efficiency of 73 percent with a relatively low over potential of 0.925V at higher temperature of 80oC. The mixture also showed to give the best electrocatalytic activity with a low Tafel slope of 30.1mV.dec-1. Whereas the Ir50Pt50 showed a comparatively lower hydrogen efficiency of 65 percent with a lower over potential of 0.6V at 50oC. Ternary mixed oxide of Ir20Ru40Co40 showed an even lower over potential of 0.5- 0.6V over a large range of temperatures with a low hydrogen efficiency of 44 percent but gave good electrocatalytic activity in terms of the Tafel slope analysis. On the other hand, mixtures with relatively cheaper material such as Nickel in binary mixture systems such as Pt50Ni50 as cathode catalyst was found to show promising performance of a relatively low over potential that was less than 1.4 V with a low hydrogen efficiency of 62.1 percent Ternary cathode catalyst materials such as Pt33Ni33Co33 exhibited good performance with higher hydrogen efficiency of 65.2 percent at lower over potential of 1.2 V and a higher Tafel slope of 133.9 mV.dec-1 at 80 0C.

- Description: The social problems that exist within South Africa cannot be ignored. The magnitude of poverty, unemployment and crime that exist are ever increasing while HIV/Aids has left 10 percent of the children within this country orphaned. Discrepancies in the access to proper healthcare and education between the private sector and the public sector is evident, mainly due to the failure of the public sector (government) to effectively implement and manage the healthcare and education systems in South Africa. In the last decade, there has been a significant increase in the number of registered non-profit organisations which can be attributed to a greater awareness of the social problems that exist, as well as the inability of the government and the public sector to address the social problems on their own. Social entrepreneurs are attempting to find innovative solutions to these problems by starting non-profit organisations and then implementing projects and programmes that will help alleviate these social problems. Social entrepreneurship is a fairly new concept, particularly within the realm of academic research. Previous studies on social entrepreneurship have highlighted the need for social entrepreneurs and have also emphasised the many challenges these social entrepreneurs face, one of which is the lack of education and business skills training. Research indicates that a non-profit organisation should be run like a small business in order to be successful, which highlights the importance for social entrepreneurs to be equipped with the appropriate business skills. The impact that a social entrepreneur’s education and business skills training has on the success of a non-profit organisation is however still largely unknown. The purpose of this study was three-fold: firstly, to study the relationship between the education and business skills training of a social entrepreneur and the successful functioning of their non-profit organisations; secondly, to develop recommendations for social entrepreneurs on how to more effectively manage their non-profit organisations and guide them in what business training will benefit them as a social entrepreneur; and lastly, to add to the already existing knowledge on social entrepreneurs, particularly within a South African context. The main research methodology used to conduct the empirical investigation in this study was qualitative in nature. Elements of quantitative data collection were adopted in the instruments in order to ensure standardisation when measuring a social entrepreneur’s education and business skills training, as well as the success of their respective non-profit organisation. In-depth interviews were conducted with fourteen social entrepreneurs who work in a variety of social developmental sectors within South Africa. An interview guide was developed to record the formal levels of education and business skills training received by the respondents and to discuss the impact of other types of education and business skills training on their capabilities as managers of non-profit organisations. A tool was developed to measure the success of the respective non-profit organisations and the results were compared to the social entrepreneur’s levels of education and business skills training. Global analysis was the data analysis technique adopted in this study and was used to identify common themes among the transcripts as well as possible relationships between different variables. There were two main findings with regard to the impact a social entrepreneur’s education and business skills training has on the successful functioning of his/her respective non-profit organisation. Firstly, the formal types of education and business skills training of a social entrepreneur have a direct impact on the success of a nonprofit organisation. Secondly, once a social entrepreneur has completed school level education, informal types of education and business skills training play a bigger role than formal types in the effective management and success of his/her respective non-profit organisation. The findings of the empirical investigation showed that the most valuable three types of informal education and business skills training include workshops and conferences, business experience and networks. The most important recommendation for social entrepreneurs is that their school level education should be completed, in order to access further education and business skills training opportunities. The social entrepreneurs must equip themselves with certain skills and knowledge, namely: financial management, legal knowledge, human resource management, strategic management, monitoring and evaluation skills, technical skills and research skills, in order to ensure the successful functioning of their respective non-profit organization.

- Description: Good governance is a critical element to economic development both at the local and national level. Devolution, which is a form of decentralization, is a means of achieving good governance if implemented appropriately. Government plays a pivotal role in the governance framework of a country. This study aimed at exploring how governance of Nairobi City can be improved under a devolved system of government to foster economic development. The study specifically looked at government effectiveness which is one of the Worldwide Governance Indicators. Through a literature review, the study looks at how devolution can improve governance, and what government effectiveness entails, not only from the World Bank perspective but also from other related literature. The major assumption of this study is that improved governance consequently leads to enhanced economic development, as argued by numerous scholars and practitioners in previous studies (Todaro and Smith, (2009) Mcneil and Malena, (2010) and UNDESA 2007). Furthermore, this study assumed that despite only focusing on one of the six indicators, an idea of good governance as a whole will be obtained. The study used a mix of qualitative and quantitative approach of a case study of Nairobi City. Nairobi City is not only a unit of devolution under the new constitution, but will also host the national government. Furthermore, it is also the financial stronghold of the country. Data was collected from two sets of respondents using two different instruments. A questionnaire was used to collect data from the citizenry, and face to face interviews were used to collect data from government officials. The questionnaire focused on capturing citizen perceptions on government effectiveness. Respondents were selected through convenient sampling at pre-determined service delivery points within Nairobi City. The face-to-face semi-structured interview gauged the level of government effectiveness of selected government institutions within Nairobi City. For the former instrument, the data was analyzed through SPSS and Microsoft Excel; and presented in tables, charts and graphs. For the latter, a descriptive discussion has been used to illustrate findings. The study found that government institutions within Nairobi to an extent have established mechanisms and systems to improve service delivery, and consequently promote government effectiveness. It is observable from the study that, the systems in place do not respond to the citizen needs and expectations as illustrated by a satisfaction index of 54 percent.

- Description: Leadership development is very important in business and often much lip service is given to “growing” leaders in business organisations. Leadership development takes place at the individual, group or organisational level and aims for greater effectiveness of an organisation’s human, social and systems capital. One of the biggest motor manufacturers in the Eastern Cape which employs more than 6 500 workers in the local plant and thousands of allied jobs at suppliers was selected to conduct this study on leadership development. The reason for choosing this company is that, over the years, the company established strong training and development programmes to help employees achieve their full potential and to grow the company. This study assesses the success of leadership development in the selected company as well as the factors that could lead to the improvement of its leadership development programme. The primary objective of the study is therefore to improve leadership development in the selected company by investigating the influence of selected factors on leadership development in that company. The sample was drawn from the employees of the company who were enrolled for leadership development at the company’s training institute as at October 2010. They were 55 engineers, 15 supervisors, 20 buyers and 12 managers. A census of these employees was conducted, in other words, 102 questionnaires were distributed to them. Only forty (40) respondents (response rate = 39.2%) however participated in the final study. The empirical results showed that three variables were key ingredients for achieving and increasing leadership development success: organisational culture, participative leadership and senior-management support. Implementing the recommendations that emanated from these results will go a long way in securing success in the company’s leadership development programme.

- Description: To achieve effectiveness and efficiency in public enterprises, change is needed. Due to the rapid changing global environment and increasing demand for service delivery, continuous change is needed. Changes have been taking place in the Kenyan public sector since 2003. The public enterprises in Kenya, like in most countries in Sub-Saharan Africa, have been characterised by slow and bureaucratic processes that retard organisational performance. Employees and managers in these enterprises have been perceived as not performing as they should. Kenyan public enterprises are important to the economy of the country. They provide social services to the Kenyan population and employ about 654 200 people. The latter translated in a wage bill of 84 378 million Kenyan Shillings (Ksh 80 = 1 US dollar). There is therefore a need to investigate ways to improve individual and organisational performance, collectively viewed as organisational effectiveness in this study, in these enterprises. It is generally accepted that leadership and organisational culture play a critical role in managing the effectiveness of enterprises. In this study, leadership style (transactional and transformational), leadership personality (Machiavellianism, narcissism, masculinity, femininity, individualism and collectivism) and organisational culture (entrepreneurial and market-orientation), strategic management, corporate ethics are investigated determinants of organisational effectiveness. A survey approach was used to collect data from 670 senior executives from 134 Kenyan public (state) enterprises. Two hundred and fifty-six (256) useful survey responses from 53 public enterprises were received. Structural equation modelling (SEM) statistical technique was used to test the hypothesised relationships between the above-mentioned determinants and the dependent variables (individual performance intention and organisational performance). The descriptive statistics of the raw data were also analysed to ascertain the managers’ perceptions about these determinants in the public enterprises. The empirical results revealed that transformational leadership exerts a positive influence on both organisational performance and individual performance intention; that self-deceptive narcissism motivates individual performance intent but decreases organisational performance; that an entrepreneurial, market and strategic management orientation positively influences organisational performance; and that strategy implementation positively influences individual performance intent. In view of these findings, the study concludes that it is critical that leadership styles and leadership personalities be taken into account in leadership recruitment and development process in Kenya public enterprises. Kenyan public enterprises will also improve their organisational performance if they implement entrepreneurial, market and strategic management principles.

- Description: To achieve effectiveness and efficiency in public enterprises, change is needed. Due to the rapid changing global environment and increasing demand for service delivery, continuous change is needed. Changes have been taking place in the Kenyan public sector since 2003. The public enterprises in Kenya, like in most countries in Sub-Saharan Africa, have been characterised by slow and bureaucratic processes that retard organisational performance. Employees and managers in these enterprises have been perceived as not performing as they should. Kenyan public enterprises are important to the economy of the country. They provide social services to the Kenyan population and employ about 654 200 people. The latter translated in a wage bill of 84 378 million Kenyan Shillings (Ksh 80 = 1 US dollar). There is therefore a need to investigate ways to improve individual and organisational performance, collectively viewed as organisational effectiveness in this study, in these enterprises. It is generally accepted that leadership and organisational culture play a critical role in managing the effectiveness of enterprises. In this study, leadership style (transactional and transformational), leadership personality (Machiavellianism, narcissism, masculinity, femininity, individualism and collectivism) and organisational culture (entrepreneurial and market-orientation), strategic management, corporate ethics are investigated determinants of organisational effectiveness. A survey approach was used to collect data from 670 senior executives from 134 Kenyan public (state) enterprises.

- Description: The DoE is structured in such a way that in all the provinces there are Districts which are formed by clusters. The performance of each province is measured according to that of the different Districts. This District performance reflects back to the schools in the clusters where they are found. Everyone is keen to know which District will be the top performer in the Grade 12 results in the Eastern Cape; because this is where performance of each school is measured. In the past years it was sad to notice that the Eastern Cape schools have had a very low pass rate. The DoE (PE) District has a challenge to change the situation in which the province finds itself. This research seeks to address the challenges encountered by the schools which are not able to improve their pass rate. It focuses on the school management systems of low pass rate schools; and how can they be modified. It is vitally important to manage the organisation or institution in a way which will optimize performance. That is the reason for discussing and debating the way school management is operated in the high pass rate schools, so that differences between the two categories of schools are noted and good strategies are utilised in low pass rate schools. For the PE District to improve; the schools in the circuits must improve in their performance. Each circuit is allocated an Educational Development Officer (EDO). It is the duty of the EDO to monitor and evaluate the schools in their circuits. These departmental officials have to ensure that schools are managed well; that is, that the school management systems are functioning properly. They need to assist the schools in any way they can, in order to improve the performance of the schools. This research study seeks to bring forward the challenges faced by the low performing schools so that every stakeholder in the schools and in the DoE is on board to improve the situation. Improvement in the circuit will help the province to enhance its overall performance.

- Description: Although open to debate, it is something of an undisputed fact and has been since the days of Florence Nightingale, that hospital management is frustrated with recurring problems - many of them due to broken processes. Hospitals are places of phenomenal healing and heroic care. However, as with any human-led endeavour, there are problems. (Grunden (2009)). A first time use of the word ‘lean’ generally begs some explaination as it is not a commonly used word. The simplest way to explain the word is by way of the introduction of the concept known as ‘lean management’. Lean management is a methodology which allows hospitals to advance the quality of patient care by reducing errors and waiting times. Lean is a system of reinforcement of hospital business for the long term thereby reducing costs and risk. Kanban (2009) states that lean is a toolset; a management system and a viewpoint that can change the way hospitals are structured and managed. Lean helps managers to comprehend and identify broken systems and to improve these in small parts, while employees aid in finding solutions for broken systems. This proposal analyses the effect lean tools have had within Arwyp Medical Centre in Kempton Park, South Africa.

- Description: The Kyoto Protocol of UNFCCC (United Nations Framework Convention on Climate Change) postulated that anthropogenic causes are the main drivers of global climate change. This Kyoto Protocol was ratified by South Africa, with South Africa accepting all the binding commitments. Since then South Africa has promulgated legislations which cater for the environment and the reduction of the greenhouse gases respectively, with the aim of promoting sustainable development. The South African constitution has recognised the environment in Section 24. This is the birth place of the “Environmental Clauses” which do not only speak to the national government but are also broken down to the provincial and local government. This study was grounded within the field of Development studies and undertook a case study of improving the socio-ecological resilience strategies of climate changes in Nelson Mandela Bay Metropole (NMBM). The study employed the use of semi-structure interviews whereby a questionnaire was used to guide the researcher in the interview process. A total of 23 officials were interviewed, ranging from governmental departments (municipality) through civil societies to private consultants, in order to avoid the generation of biases. The data obtained from respondents were presented, analysed, and discussed. From the data collected, it was possible to single out certain barriers to climate change resilience initiative in NMBM. Some of these barriers include the lack of awareness of climate change resilience issues, lack of political will, lack of funding, and the poor concern given to climate change issues since the municipality does not consider it a core issue. Based on the study findings, the main recommendation offered to NMBM was the creation of a Sustainable Development Framework, which will provide a perfect platform for development, acknowledge the threat posed by the negative effects of climate change, and enhance opportunities to execute climate change projects in NMBM.

- Description: The principal together with the school management team (SMT) of a public school is responsible for ensuring that all areas in the school function effectively. Effective school-based management is no longer a choice in South Africa but, rather, a must. Seventeen years into democracy, the Grade 12 pass rates in the Eastern Cape for the past three years were 50.6% in 2008, 51.0% in 2009 and 58.3% in 2010. Although there has been an improvement over the last three years, the Eastern Cape was still number seven out of the nine provinces in 2010. Against this background the question arose as to whether the schools in the Eastern Cape were effectively managed. The primary objective of the study is therefore to improve the organisational performance of public schools in the Uitenhage education district by investigating the relationship between the perceived effective implementation of basic managerial tasks (planning, organising, leading and controlling), on the one hand, and organisational performance of schools, on the other hand. Convenience sampling was used to select 100 out of a possible 139 senior management team members from 26 public schools in the Uitenhage education district. The sample was stratified to include principals, deputy principals and heads of departments. The empirical results revealed that the management tasks, leading and controlling, were the main determinants of the organisational performance of participating schools. The empirical results showed that planning and organising do not have a significant influence on the organisational performance of these schools. The managerial implications of the results are discussed and recommendations are made on the basis of these discussions.

- Description: In Africa, use of medicinal plants for the treatment of diabetes is very common. However, efficacy on co-administering of medicinal plants with therapeutic drugs hasn't been fully determined, especially for African medicinal plants. The current study focused on assessing the in vitro modulation effects of three popular African medicinal plants, namely: Aloe ferox, Sutherlandia frutescens and Prunus africana (including five commercial preparations containing these medicinal plants) on two of the most important anti-diabetic drug metabolising enzymes, Cytochrome P450 (CYP450) 2C9 and CYP3A4 and a key drug efflux transporter, P-glycoprotein (P-gp). Vivid® microsome-based screening kits were used to assess inhibitory potency of plants preparations on CYP2C9 and CYP3A4 enzymes activities. The study showed that P. africana was a more potent inhibitor of CYP2C9 and CYP3A4 activity than the corresponding positive controls Ginkgo biloba and St. John's wort, which are known to cause clinically significant drug-herb interactions. S. frutescens leaf extract demonstrated potent to moderate inhibition on both the tested CYP activities, while its commercial products (Promune® and Probetix®) possessed moderate to mild inhibitory effects on the activities of both CYPs. Potent inhibitory effect on CYP2C9 and CYP3A4 was seen with Aloe Ferox®. Prosit® and Aloes powder® showed potent to moderate inhibition on CYP2C9 activity and moderate to mild inhibition on CYP3A4 activity. In addition to CYP450 activity, the present study also investigated the effects of the selected medicinal plant products on the activity of the main drug efflux protein, P-gp. A screening assay was specifically developed to assess the potential for herbal remedies to interact with P-gp mediated drug absorption. The assay is based on the principle of the reversal of drug resistance in modified Caco-2 cells specifically altered to express high iv efflux protein activity. These cells display a multidrug resistance phenotype and the addition of a plant extract containing a P-gp inhibitor or substrate will inhibit or compete with any cytotoxic drug and consequently reverse the drug resistance. The suitability of the assay was confirmed using a known P-gp inhibitor. The study observed that the anti-proliferation effect of vinblastine was significantly enhanced in vinblastine-resistant Caco-2 cells, which have high P-gp expression, when they were exposed to the selected African herbal preparations. This observation indicates that the studied plant preparations may alter P-gp functionality and therefore lead to interference with the absorption of co-administered drugs. The outcomes of this study provide useful information on whether there are any potential drug-herb interactions between the commonly used African medicinal plants and oral anti-diabetic drugs, at the level of CYP and P-gp drug metabolism and could contribute to better therapeutic management of Type II diabetics. However these predicted interactions will need to be verified in a clinical setting.

- Description: The aim of the study was twofold namely (1) to describe and compare the incidence and mechanism of injuries that occurred in the Nelson Mandela Metropolitan University hockey teams that play in the Premier and President Leagues; and (2) to determine the relationships between the level of physical preparation of the relevant players and injury occurrence. The study utilised an exploratory-descriptive epidemiological approach, implementing a cohort study design and was conducted over a period of six months. Data collection was done by means of two physical tests, one to assess the players’ endurance and the other to assess their anaerobic fitness. This was performed twice on the participants during the study. Data collection also utilised four questionnaires to determine the following: the players’ personal information and medical history, the preparation and training the players did for hockey, the incidence and mechanism of the injury the players have incurred and the follow-up of the injury to describe the type of injury and the rehabilitation process. The study included 42 participants with 25 from the two Premier League Teams and 17 from the President League Team. The results were placed into table and graph format and elucidated by means of descriptive statistics. Furthermore inferential statistics and Cohen’s d were utilised to determine both statistical and practical significances of differences between groups mean values respectively. The statistical significance of differences between the frequency distributions of the two sample groups was determined by means of Chi2 tests of independence. Cramér’s V statistic was used when there were statistically significant Chi2 tests results to determine the practical significance of the two sample group’s differences. The variable of highest level of play showed the only significant difference with regards to screening statistics as the Premier League Participants had a higher number of years participating at a provincial level. The injury statistics revealed that the incidence of injury in the Premier League was 4.08 injuries per 1000 athlete-exposures (A-E), while there was a significantly higher incidence for the President League of 14.71 injuries per 1000 A-E. Matches showed a significantly higher incidence of injuries (8.18 injuries per 1000 A-E) than xiv practices (2.42 injuries per 1000 A-E) which follows previous research. Goalkeepers and halves showed the highest occurrence of injuries (36 percent each) and are supported by 59 percent of the injuries occurring on the defensive side of the 23 metre line. Contact injuries (collision 6 percent, hit by stick 17 percent and hit by ball 33 percent) accounted for 56 percent of all the injuries. No significant differences were found between the two leagues with regards to preparation, the Multi Stage Shuttle Run Test (MSSRT) and the Repeated Sprint Test (RST), except for one period each for technical skills and aerobic training. The relationship between injuries and training showed no significances with regards to preparation, MSSRT and RST, although there was minimal balance and proprioceptive training performed. Thus the lower league showed a significantly higher incidence of injury with preparation not being a mechanism for injuries.

- Description: In a fragmented and competitive industry, it is likely for the smaller roleplayer to be challenged in terms of competitiveness and market share. It is, therefore, important for the smaller organisation to etch its position in the market, by increasing its competitive advantage. In a milieu where there is a shift in distribution dynamics and the balance of power, and an increase in consumerism, the need to react is a pressing issue to be addressed by the smaller player. In the context of this study, the small and medium-low-impact intermediary in the South African short-term insurance industry is under pressure from, among others, direct distribution models and the increasing volume of the medium-high and high-impact intermediaries. It is determined in this study that the intermediary is challenged by all five market forces, as postulated by Porter in the model of “the five forces that shape industry competition”. The intermediary organisation must adopt positioning strategies, and differentiate its offering, in order to stay relevant in the industry. The short-term insurance intermediate industry is classified as a service industry; and therefore, it has unique factors to attend to. The positioning and differentiation strategies must be implemented without compromising the service quality levels. Furthermore, in the development of positioning strategies, it is essential to investigate the traditional marketing mix, while amplifying the mix with contemporary views of the subject. These form the basis of the positioning strategy; and from there, differentiation offerings can be shaped. A survey analysis of the product suppliers aims to identify the most important strategies for success. The study relies on the industry knowledge of the executives of these organisations, to steer the positioning strategies of the intermediary to fit in with their own positioning in the marketplace.

- Description: The advent of the 21st Century has seen a number of technological developments which affect almost every spectrum or aspect of our lives. Castells (2001) likens the power of ICT to the impact that access to electricity and clean running water in a community have had on human development. In the field of educational, information and communication technology (ICT) has become a core part in helping to improve the efficiency and productivity of both teaching and learning of any particular subject (Fallows and Bhanot, 2002).The aim of this study was to investigate to what extent ICT had enhanced learning at Pearson High School in the Summerstrand area of the Nelson Mandela Bay Municipality (NMBM). The results of the study were compared with similar studies in other schools in NMBM conducted at the same time. The study was qualitative and methods of data collection used were key informant interviews and focus group discussions.

- Description: In today’s world, information and the associated Information Technology are critical assets for many organizations. Any information security breach, or compromise of these assets, can lead to serious implications for organizations that are heavily dependent on these assets. For such organizations, information security becomes vital. Organizations deploy an information security infrastructure for protecting their information assets. This infrastructure consists of policies and controls. Organizations also create an information security management system for managing information security in the organization. While some of the policies and controls are of a purely technical nature, many depend upon the actions of end-users. However, end-users are known to exhibit both compliant and noncompliant behaviours in respect of these information security policies and controls in the organization. Non-compliant information security behaviours of end-users have the potential to lead to information security breaches. Non-compliance thus needs to be controlled. The discipline of information security and its management have evolved over the years. However, the discipline has retained the technology-driven nature of its origin. In this context, the discipline has failed to adequately appreciate the role played by the end-users and the complexities of their behaviour, as it relates to information security policies and controls. The pervasive information security management philosophy is that of treating end-users as the enemy. Compliance is sought to be achieved through awareness programs, rewards, punishments and evermore strict policies and controls. This has led to a bureaucratic information security management approach. The philosophy of treating end-users as the enemy has had an adverse impact on information security in the organization. It can be said that rather than curbing non-compliance by end-users, the present-day bureaucratic approach to information security management has contributed to non-compliance. This thesis calls this the end-user crisis. This research aims at resolving this crisis by identifying an improved approach to information security management in the organization. This research has applied the service management approach to information security management. The resultant Information Security Service Management (ISSM) views end-users as assets and resources, and not as enemies. The central idea of ISSM is that the end-user is to be treated as a customer, whose needs are to be satisfied. This research presents ISSM. This research also presents the various components of ISSM to aid in its implementation in an organization.

Innovations introduced into the South African criminal justice by the child justice Act 75 of 2008

- Description: The Child Justice Act 75 of 2008 has brought about some new elements in the South African Criminal Justice system in cases involving children in conflict with the law. The changes require that children in conflict with the law should be treated differently from adult accused persons. The Act is now regarded as a Criminal Procedure for children in conflict with the law. In other words the emphasis is on ensuring that children are diverted away from the formal Criminal Justice provided that children acknowledge responsibility. One of the elements that is introduced by the Act is the Preliminary Inquiry that is an informal, pre- trial procedure that must be held in respect of every child that is alleged to have committed an offence. The role of the Presiding Judicial Officer is very active during this stage because he is the one that takes charge of the proceedings and the role of the Prosecutor and the Legal Representative is very minimal. The purpose of the Preliminary Inquiry is in the main to determine whether a child in conflict with the law could be diverted if the provisions of section 52 (1) of the Act are complied with. Preliminary Inquiry if properly used will have possible benefits for the South African Criminal Justice system in that cases involving children will be timeously be finalised and the turn around time for criminal cases in general will possibly improve. Same will translate in the confidence of the citizens being improved in the Justice system. The second element that is introduced by the Act is formalised diversion into the Criminal Justice System. Diversion had for a number of years before the coming into operation of the Child Justice Act been used in South Africa but it was informal. The diversion that is envisaged by the Act is restorative in nature in that the Act seeks to involve the child offender, the victim, the community members to collectively identify and address harms, needs and obligations through accepting responsibility, making restitution, taking measures to prevent recurrence of the incident and promoting reconciliation. Restorative Justice is not a new invention in the South African legal system it is a return to traditional patterns of dealing with conflict and crime that had been present in different cultures throughout human history. Restorative Justice has been understood as Ubuntu in the African context. The Truth and Reconciliation Commission demonstrated the benefits of restorative justice in dealing with conflicts that had a potential of setting the country alight. Restorative Justice has evolved in South Africa throughout different historical epochs up to the current legal conjuncture. It has now been endorsed with success in precedent setting cases in the High Courts of the Republic and the Child Justice Act has now fully institutionalised it into the Criminal Justice system. One hopes that it will be extended beyond cases involving children in conflict with the law but to adult accused persons. Various pieces of legislation attempt to endorse the principles of restorative justice but are not as comprehensive as the Child Justice Act. There are 4 instances where a matter may be diverted in terms of the Act: (i) By a Prosecutor in terms of section 41; (ii) Diversion at Preliminary inquiry; (iii) Diversion before the closure of state case at trial; (iv) At any time during trial but before judgement. There are 2 diversion options that are provided by the Act that is level one diversion option in respect of schedule 1 offences and level 2 diversion options in respect of schedule 2 and 3 which are much more serious. The Act further entrenches Family Group Conference as well as Victim Offender Mediation which are restorative justice mechanisms. The legal consequences of diversion are that when the child has successfully complied is equivalent to an acquittal. The last element is the multi sectoral approach to crime fighting in that all role players should work together in dispensing justice to children in conflict with the law. The days of working in silos are now over because everybody has a role to play and there has to be collaboration at all levels. The Act entrenches the public private partnerships particularly in helping to rehabilitate and reintegrate children to society. The Act provides for the establishment of One Stop Child Justice Centres. The purpose is to promote cooperation between government departments, non governmental organisations and civil society to ensure integrated and holistic approach in the implementation of the Act. The Act further provides for the development of the National Policy Framework by the Departments of Justice and Constitutional Development, Social Development, Correctional Services, South African Police Services, Education and Health within 2 months of the commencement of the Act. The purpose is to ensure uniform, coordinated and cooperative approach by all government departments, organs of state and institutions in dealing with matters of child justice and enhance service delivery. This study seeks to examine the innovations brought about by the Child Justice Act into the South African Criminal Justice System. The study further explores the possible benefits that may accrue to the Criminal Justice System because of Preliminary Inquiry, Restorative Justice and the Multi Sectoral Approach to crime.

- Description: Mobility has become a substantial part in our society. Since we spend a lot of our available time on the road, we expect the automotive environment to provide similar comfort levels than residential buildings. Within this context, this research thesis especially focuses on automotive thermal comfort control. The automotive cabin is a very special environment, which is characterized by extreme inhomogeneity and overall transient behavior. Thermal comfort is a very vague and a very subjective term, which depends on physiological and psychological variables. Theories for thermal comfort in transient environments have not been fully established yet and researchers are still busy with its investigation. At present, automotive industry relies on extensive thermal comfort models, manikins and powerful simulation tools to assess and control thermal comfort. This thesis studies the application of artificial intelligence and proposes a blackbox approach which aims for extracting thermal comfort knowledge directly from human's interaction with the HVAC controls. This methodology avoids the use of human physiological and psychological thermal comfort models and does not require any a-priori knowledge. A novel comfort acquisition tool has been developed and has been integrated into a research vehicle in order to gather the required data for system learning. Data has been collected during spring, autumn and summer conditions in Southern Africa. Methods of data mining have been applied and an intelligent implementation using artificial neural networks has been proposed. The achieved results are promising and allow for about 87 perecent correct classification. It is concluded that methods of artificial intelligence perform well and are far superior compared to conventional approaches. These methods can be used as a powerful tool for the development process of vehicle air-conditioning controls and have great potential for time and cost reduction.

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