- Description: Research studies and the review of academic literature has found that strategic leadership had a direct impact on organisational climate, and that climate in turn accounted for nearly one third of the financial results of organisations (Goleman, 2000). The conclusion from research conducted across 13 industries established that over a 20 year period, leadership accounted for more variations in performance than any other variable (Northouse, 2006). This thesis confines its research to a case study on Famous Brands. Famous Brands is currently one of Africa’s leading Quick Service Restaurant and Casual Dining franchisors and is also represented in the United Kingdom. The Group also has a manufacturing arm and supplies its franchisees, the retail trade and the broader hospitality industry with a wide range of meat, sauce, bakery, ice cream, fruit juice and mineral water products. At the time when the company’s name changed from Steers Holdings to Famous Brand in 2004, Kevin Hedderwick was appointed as Chief Operating Officer. The research examines how Kevin Hedderwick has exercised strategic leadership and thereby influenced Famous Brands’ performance. Hedderwick displays qualities, attributes and behaviours that are characterized by the phenomenon of “strategic leadership”. A quantitative analysis of Famous Brands financial performance (between 2005 and 2009) was undertaken. Further qualitative descriptions were used to further give meaning to the financial results. The success experienced by Famous Brands since Hedderwick’s appointment, seem to suggest that strategic choices and initiatives have been met with great success. The research is presented in the form of a case study that can be developed into a teaching case to be used in the classroom to illustrate the exercise of strategic leadership. The researcher explored a qualitative research framework by collecting and assimilating data from available documentation, and from a formal interview that was conducted with Mr Hedderwick. Information was also obtained from interviews that were conducted with other senior executives and influential personnel. This research concludes that the success of organisations is dependent on the interventions of a strategic leader who displays a specialist set of skills and behaviours. These strategic leaders have the ability to successfully influence their employees, thereby creating an enabling environment for the implementation of their strategic choices.

A comparative analysis of the development of performers' rights in the United Kingdom and South Africa

- Description: Although performers have been rife for centuries, no legal regime was required for their protection owing to the fact that the nature of their performances was transitory. It was not until the invention of the phonogram in 1877, that the need to provide performers with the means to protect the unauthorised uses of their performances became an issue. The subsequent development of performers' rights has been fuelled by the rapid technological developments of the modern age which has prompted the international community to respond through various international instruments. Performers initially sought protection in terms of the Berne Convention in 1886, but it was not until the Rome Convention in 1961 that performers were first accorded international recognition. This was followed by the TRIPs Agreement in 1994 and the WPPT in 1996. This work involves an investigation into the historical development of performers' rights in the United Kingdom and South Africa. This is followed by a comparative analysis of the current state of performers' rights as between the United Kingdom and South Africa with a view to proposing recommendations for improving the level of protection accorded performers in South Africa. Arguments in favour of a regime of performers' rights as well as possible counter-arguments have been advanced. The general development of performers' rights as a related or neighbouring right to copyright is focussed on. The development of performers' rights in the United Kingdom is discussed with reference to the first English legislative form of protection, namely the Dramatic and Musical Performers' Protection Act, 1925. This Act only provided performers with criminal remedies, a view that prevailed through several subsequent enactments designed to protect performers as a result of ratification of the Rome Convention. It was not until 1988 when the decision in Rickless v United Artists Corp prompted the legislature to grant performers with enforceable civil remedies through the enactment of the Copyright, Designs and Patents Act, 1988. Several European Union Council Directives aimed at harmonising the law relating to performers' rights throughout the Union were issued, mainly in response to the TRIPS Agreement. In order to comply with these Directives, the United Kingdom passed Regulations to bring about the necessary amendments to the Copyright, Designs and Patents Act. Performers in the United Kingdom were granted moral rights in 2006 as a result of the United Kingdom's ratification of the WPPT. The development of performers' rights in South Africa has been slow when compared to that of the United Kingdom. It was not until 1967 that performers were first legally recognised in South Africa. Although South Africa has yet to ratify the Rome Convention, it was stated in South African Broadcasting Corporation v Pollecutt that the Act was clearly passed with a view to complying with the Convention. South Africa's ratification of the TRIPs Agreement brought about amendments to the Act, particularly regarding the duration of protection which was increased from 20 to 50 years. Although South Africa played an active role in the conclusion of the WPPT, it has yet to ratify it. However, amendments were made to the Act in line with this Treaty, such as the incorporation of “expressions of folklore” within the ambit of protection, and the granting of a right to receive royalties whenever a performer's performances are broadcast. This is commonly known as needletime. South Africa's reluctance to grant performers with moral rights as provided for by the Treaty is noteworthy. The introduction of needletime into South African law has resulted in a fierce debate between collecting societies (who represent authors and performers) and the NAB (who represent users of performances). Mainly as a result of this dispute, performers in South Africa have, to date, not received any royalties due to them. The protection of traditional knowledge has also received attention of late with the Intellectual Property Laws Amendment Bill, 2010 which aims to bring traditional knowledge inter alia within the ambit of the Performers' Protection Act. The current state of performers' rights in the United Kingdom and South Africa are compared in order to identify ways in which the level of protection accorded performers in South Africa could be improved. The Copyright, Designs and Patents Act is compared with the Performers' Protection Act through emphasis being placed on the definition of a “performer”; the definition of a “performance”; the nature of performers' rights; exceptions to infringement; the term of protection; the retrospectivity of the legislation; and the enforcement measures in place. Upon analysis, it was found that the Performers' Protection Act can be amended in several ways in order to increase the level of protection accorded performers in South Africa.

- Description: Prior to 1990, very few countries in the world offered special protection to child witnesses interfacing with the justice system. There were no legal provisions permitting testimonial accommodations for children in court. The courtroom experience was significantly traumatic for the children. With the international focus shifting from protecting and upholding the rights of the accused in the courtroom towards a more victim-centred approach, various international and regional instruments have strongly dvocated that children deserve special protection because of their vulnerability. In order for the courts to be able to elicit accurate evidence from the child without further traumatizing the child, research has shown that the child needs assistance. An intermediary may be defined as a person who facilitates communication between the child and the courtroom in a manner that takes into account the child‟s cognitive and developmental limitations. The thesis was prompted by the need to make a contribution to the currently limited body of literature on the intermediary systems in South Africa, Namibia, Zimbabwe and Ethiopia by investigating how the systems can be improved and sustained in a way that helps to protect the child witness in court. Despite the problems the South African courts have had in identifying the appropriate interpretation of its intermediary legislation, the country emerges as a clear leader for the steps it took by creating a positive legal framework within which child protection issues are addressed and introducing the concept of the intermediary. This concept proved to be an inspiration to its neighbours, Namibia and Zimbabwe. The influence of the South African intermediary legislation is evident in the Namibian and Zimbabwean legislation. Although Namibian legislators have drafted laws that permit intermediary assistance in court, there are as yet no intermediaries appointed. In Ethiopia, although there is no discernible intermediary legislation, the country has managed to establish an intermediary system. As a result of the analysis conducted, it is evident that the efficacy of the intermediary system is dependent on the presence of an enabling legislation, its clarity and ease of interpretation, the sensitisation of court role players on child vulnerabilities, the significance of intermediary assistance, and finally a government's commitment towards the implementation process.

- Description: The purpose of this study was to compare the dispute resolution systems of Botswana and South Africa. As far as the South Africa dispute resolution system is concerned extensive literature on the system was carried out to describe its functioning. As for the Botswana dispute resolution system there was not much written about it in the literature, so in order to find out more about this system semi-structured interviews with labour relations experts which include mediators, arbitrators, lecturers, labour lawyers, trade unionists, employers and government officials held. The framework of comparison was developed to compare the elements of dispute resolution systems against each other and secondly to compare each system against the criteria of performance to the system. The two labour relations systems were compared in terms of elements of the system and the performance of the two systems. In the comparisons of the elements of the systems it was found out that in both systems the nature of disputes was collective and individual disputes both of which can be referred to the initial process of mediation or conciliation. However, in Botswana collective disputes can only be referred to arbitration if they remain unresolved in mediation while in South Africa only collective disputes on essential services go to arbitration while others lead to a strike or lockout if unresolved at conciliation. As for coverage both systems have incorporated public service sector employees in the systems after being excluded from the system for a very long time. The only difference is that in Botswana the Police force is not included while in South Africa they are included in the system. Differences in the avenues of disputes in the two countries were noted, in Botswana the rights/individual disputes go to either arbitration or Industrial Court if unresolved at mediation, inter-est/collective disputes can only go to arbitration while in South Africa the route of disputes is specified in the legislation. As for the human resources of the two countries it was found that the South African system has more qualified, trained and sufficiently experienced staff than the Botswana system. As for the processes it was found that for South Africa the initial process is conciliation while in Botswana it is mediation but these two processes were similar in many ways, from mediation/conciliation the next step in both systems is arbitration and just like the conciliation/mediation, arbitration in both countries was found to be similar except that in South Africa it is a public hearing. The two systems were also compared in terms of their performances and the research has established that between the two systems the South African system proved to be more superior on three of the criteria; efficiency, accessibility and legitimacy than the Botswana system. Therefore, the research proposes a number of recommendations for Botswana to implement namely; establishment of a legislated mixed process of mediation-arbitration, making the dispute resolution system independent from government, recruitment of high qualified and experienced staff for mediation and arbitration, accreditation to private agencies, effective case management system and proper routing of disputes.

- Description: African sharptooth catfish, Clarias gariepinus (Burchell 1822), is widely distributed with a natural range that extends from southern Turkey to the Orange River, South Africa (Skelton 2001). In addition to translocations within its southerly range (Cambray 2003), Cambray (2005) noted that as a result of poor aquaculture practices and introductions from a number of unknown sources, C. gariepinus has now invaded South America, Europe, Asia, and Australia. Its life history characteristics include a fast growth rate to a maximum length of 1300mmtotal length (TL) (Bruton 1976), a high fecundity, an omnivorous diet and the ability to breathe air (de Moor & Bruton 1988; Cambray 2003). Understanding the biology and population dynamics of this invader would assist in its management and possibly eradication.

- Description: Modernization is a solution to migrate cumbersome existing systems to a new architecture for improved longevity of business processes. Three modernization approaches exist. White-box and black-box modernization are distinct from one another. Grey-box modernization is a hybrid of the white-box and black-box approaches. Modernization can be utilised to create data services for a Service Oriented Architecture. Since it is unclear which modernization approach is more suitable for the development of data services, a comprehensive evaluation framework is proposed to evaluate which of the white- or black-box approaches is more suitable. The comprehensive framework consists of three evaluation components. Firstly, developer effort to modernize existing code is measured by acknowledged software metrics. Secondly, the quality of the data services is measured against identified Quality of Service criteria for data services in particular. Thirdly, the effectiveness of the modernized data services is measured through usability evaluations. By inspection of the combination of application of each of the evaluation components, a recommended approach is identified for the modernization of data services. The comprehensive framework was successfully employed to compare the white-box and black-box modernization approaches applied to a case study. Results indicated that had only a single evaluation component been used, inconclusive results of the more suitable approach may have been obtained. The findings of this research contribute a comprehensive evaluation framework which can be applied to compare modernization approaches and measure modernization success.

- Description: This study considers the nature of South African municipal water service delivery, and how marketing strategies can provide a framework for better management of this service. It reflects on the elements that guide municipal decision making and evaluates user preferences for levels of the municipal “water service mix” by employing conjoint analysis. Particular attention is paid to consumer willingness to pay for improvements in the “water service mix”. The study argues that the values municipal consumers attach to the variables of the water service mix need to be better incorporated into decision making regarding water service delivery, and that conjoint analysis is an informative method to assist in generating this information. The study outlines a water service marketing challenge and methods of research followed to deal with it (Chapter One) and the nature of the laws and institutions governing water service provision in South Africa (Chapter Two). The task of providing water services is delegated to Water Service Providers (municipalities). The key variables of the water service mix from the consumers perspective include; quality of the water, rate of flow from tap, interruption of water flow, sewerage disposal, assurance of supply, and water service tariffs (Chapter Three). The study covers the areas of Amathole, Kouga and Nelson Mandela Bay Municipalities' (Chapter Five). The method of marketing analysis applied is conjoint analysis, alternatively known as choice experiment analysis. An overview of the method is provided and its application to three samples of one hundred residents at each of the study sites is described in Chapter Four. The responses of the three hundred residents provide the basis for the results. Respondents were requested to make a series of choices between alternative water service mixes consisting of six variables differentiated by three levels (Chapter Three). In making these choices they implicitly compared and weighed up the relative worth of the selected variables against each other. The findings of the analysis were diverse (Chapter Six); two of the three estimated models did not yield significant results. An interpretation of these results showed that the respondents of the Kouga municipality were willing to pay R65.05 more (per 10 xii Kilolitres of water) than their current monthly tariff for a marginal improvement in water quality, R57.29 more (per 10 Kilolitres of water) per month for a marginal improvement in sewerage disposal and R21.90 (per 10 Kilolitres) per month for marginal improvements in assurance of water supply. Findings showed that willingness to pay for reduced interruptions and improved flow rates was lower and not as highly valued as the abovementioned variables. Most of these findings were consistent with similar international and national studies showing their reliability. Although there has been significant improvement in extending the reach of the network since 1994, the standards of water service provision in South African municipalities do not appear to have improved. The results of this study mirror a number of concerns that have been expressed about the standards of service, particularly sanitation (in publications like the Green Drop Report). Municipal service delivery in these areas would appear to be constrained by a number of issues including a lack of public involvement, legislation, limited financial resources and institutional capabilities. However, it is a service that is too vitally important to be allowed to deteriorate. Marketing analyses can make a valuable contribution to allocating and managing the scarce resources to best satisfy the consumers of water services (Chapter Seven). When consumer orientation is formally introduced as the main objective into the thinking of the service provider, it becomes untenable to offer poor service delivery. But that is exactly what many municipalities appear to be doing. There is a need to get back to the basics – where the consumer is king. This analysis concludes that consumers want, above all else, assurance of water supply, a high quality of water, and safe environmentally sensitive disposal of waste water. It is recommended that municipalities not lose sight of the fact that price is an important part of the marketing mix. From the paying consumers perspective, when the government incorporate too many other considerations into pricing of water services they are, in effect, disengaging price from the marketing mix by not being sensitive to consumer needs. This approach shows a weak marketing strategy, and may result in dissatisfied consumers who may become unwilling to pay for their water services – an outcome that the researcher would discourage.

- Description: There has been an increasing interest in survival analysis with interval-censored data, where the event of interest (such as infection with a disease) is not observed exactly but only known to happen between two examination times. However, because so much research has been focused on right-censored data, so many statistical tests and techniques are available for right-censoring methods, hence interval-censoring methods are not as abundant as those for right-censored data. In this study, right-censoring methods are used to fit a proportional hazards model to some interval-censored data. Transformation of the interval-censored observations was done using a method called mid-point imputation, a method which assumes that an event occurs at some midpoint of its recorded interval. Results obtained gave conservative regression estimates but a comparison with the conventional methods showed that the estimates were not significantly different. However, the censoring mechanism and interval lengths should be given serious consideration before deciding on using mid-point imputation on interval-censored data.

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

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

- Description: Recruitment, selection and transfer of educators were decentralized after South Africa became a democratic state in 1994 and shifted to School Governing Bodies. The legislation promoted a shared governance and participation of parents in issues that are related to recruitment, selection and transfer of educators, but parents are struggling and facing challenges in performing these tasks as School Governing Body members especially in the Butterworth district, as a result of that Butterworth district is experiencing problems with increasing number of disputes resulting from the appointment of educators after they have been recommended by the School Governing Bodies. This study focuses on the recruitment, selection and transfer of educators in the Butterworth district of the Eastern Cape Province of South Africa. The study sought to reveal the thinking behind government insistence on giving the School Governing Bodies a responsibility to recruit, select and transfer educators knowing fully well that they do not perform this responsibility. A qualitative approach was used to explore and challenge this phenomenon. This approach is concerned with understanding social phenomenon from the participant’s perspective. In depth semi – structured interviews with open ended questions were used to bring the researcher more closer to a more plausible perspective of this phenomenon. Moreover, they were used because they are the most appropriate method to capture the data. The findings revealed that School Governing Bodies are faced with challenges such as: high level of illiteracy, manipulation of School Governing Bodies by school management, unions and candidates, the issue of regionalism and kickbacks, capacity building and empowerment and role played by the Departmental Officials. By conducting this study, we hope that the findings might contribute in identifying the disjuncture between the policy and the practice in issues pertaining to educator recruitment, selection and transfers. , Thesis (MMED) -- Faculty of Educational Sciences, 2011

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

A critical analysis of the tax implications for small and micro businesses

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

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

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

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

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

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

A framework for the adoption of enterprise resource planning (ERP) systems in higher education

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

- Description: The use of Network Telescope systems has become increasingly popular amongst security researchers in recent years. This study provides a framework for the utilisation of this data. The research is based on a primary dataset of 40 million events spanning 50 months collected using a small (/24) passive network telescope located in African IP space. This research presents a number of differing ways in which the data can be analysed ranging from low level protocol based analysis to higher level analysis at the geopolitical and network topology level. Anomalous traffic and illustrative anecdotes are explored in detail and highlighted. A discussion relating to bogon traffic observed is also presented. Two novel visualisation tools are presented, which were developed to aid in the analysis of large network telescope datasets. The first is a three-dimensional visualisation tool which allows for live, near-realtime analysis, and the second is a two-dimensional fractal based plotting scheme which allows for plots of the entire IPv4 address space to be produced, and manipulated. Using the techniques and tools developed for the analysis of this dataset, a detailed analysis of traffic recorded as destined for port 445/tcp is presented. This includes the evaluation of traffic surrounding the outbreak of the Conficker worm in November 2008. A number of metrics relating to the description and quantification of network telescope configuration and the resultant traffic captures are described, the use of which it is hoped will facilitate greater and easier collaboration among researchers utilising this network security technology. The research concludes with suggestions relating to other applications of the data and intelligence that can be extracted from network telescopes, and their use as part of an organisation’s integrated network security systems
