  • Description: The Orange-Fish and Cookhouse tunnels that are part of a major inter-basin water transfer scheme (IBT) act as a pathway for several fish species from the Orange River system to enter the Great Fish and Sundays River systems in South Africa. These include Labeo capensis and L. umbratus. Labeo capensis was restricted to the Orange River system before the inter-basin water transfer scheme. Labeo umbratus occurred naturally in the Orange River and in southern flowing river systems. Previous studies showed that the two species hybridise in Hardap Dam, located in a tributary of the Orange River system in Namibia. There are also unconfirmed reports of hybrids from Darlington Dam on the Sundays River system. The aim of the thesis was to confirm hybridisation in Hardap Dam, assess whether hybridisation between L. capensis and L. umbratus has occurred in Darlington Dam and to gain a better understanding of the diversity of these two species. Morphology (morphometrics and meristics), a nuclear S7 intron and the mitochondrial cytochrome ♭ gene were used to assess for hybridisation. A total of 275 specimens were analysed from across the geographical range of the two species. The two species could be distinguished using morphometrics (dorsal fin base, interorbital width and operculum to eye distance) and meristics (lateral line, origin of the dorsal fin to lateral line, origin of the pelvic fin to lateral line and caudal peduncle scale counts) characters. Hybrids from Hardap and Darlington dams were placed between the two species clusters. Labeo umbratus from the Orange River and southern flowing rivers formed a single cluster. The two species could also be distinguished from each other with six nuclear DNA mutations and hybrids were heterozygous at such sites in both dams. Labeo umbratus populations from the Orange River and southern flowing rivers (Gouritz, Gamtoos, Sundays, Bushmans, Great Fish and Nahoon) formed a single lineage. Analysis of mitochondrial DNA, however, revealed that L. umbratus populations from the Orange River and southern flowing rivers were two lineages that differ from each other by 5 mutations. Labeo capensis could be differentiated from both these lineages. Being maternally inherited, mitochondrial DNA did not reveal hybridisation, but ten specimens with L. capensis haplotypes were found in the Darlington Dam. In Hardap Dam, however, it appears that only L. capensis mitochondrial DNA haplotypes persist, despite morphological and nuclear DNA analysis suggesting that both morphs and hybrids of the two species occur. The genetic integrity of these Labeo species has therefore been compromised in at least Hardap and Darlington dams. The Great Fish and Sundays populations are considered to be under threat of complete introgression. The Kat River and Slagboom Dam populations that were isolated before the IBTs have to remain isolated to protect the genetic integrity of the southern lineage of L. umbratus in these two systems.

  • Description: The name Albuca caudata Jacq. has been widely misunderstood or even ignored since its description in 1791. After studying herbarium specimens and living populations in South Africa, plants fitting Jacquin´s concept of that species are found to be widely distributed in the Eastern Cape, mainly in the Albany centre of Endemism. Furthermore, some divergent specimens matching Baker´s concept of Albuca caudata are described as a new related species: Albuca bakeri. Data on typification, morphology, ecology, and distribution are reported for both taxa. Affinities and divergences with other close allies are also discussed.

  • Description: This study sought to investigate the practices of citizen journalists in the Iindaba Ziyafika project. The objectives of the research were to explore the evolving practices of citizen journalism in Grahamstown and to extrapolate how citizen journalists are securing a discursive space in relationship to conventional journalism. The study investigated whether the citizen journalists based at Grocotts Mail and Radio Grahamstown are developing practices and patterns that can be distinguished from the practices of conventional journalism. It also evaluated whether the content that is produced by citizen journalists differs from the content that is produced by professional journalists, so that it can be understood as "alternative" and as promoting engaged citizenship. A sub goal was also to explore whether citizen journalism does enable the practice of citizenship through expanding the public sphere. The findings of the research are that in the Iindaba Ziyafika project, citizen journalists see news as a process and not as a series of news events. This is clear departure from event-based news conceptualisation associated with mainstream journalism. They view news as unfolding social processes, allowing citizen journalists to question the factors which would have precipitated the event and investigate the causal factors of particular phenomena. The research also reveals that citizen journalists in the project are engaging in pro-am journalism. Part of the practice of citizen journalists involves a very significant amount of collaboration between professional journalists and citizen journalists. The collaboration is in the production of content and in the presentation of radio broadcasts. Part of the findings of the study are that journalists in the Iindaba Ziyafika project work in different mediums and this calls for them to acquire the competencies of the different mediums. The same citizen journalists produce content for print, radio and for online media. The diction used in the stories published by citizen journalists is couched in struggle and revolutionary language which seems to pit the community against the authorities. The citizen journalists also make use of every daily language in their radio broadcasts and borrow from their cultural expression. This they do through populist methods. The citizen journalists have also integrated communication brokering as part and parcel of their practice. This is because the citizen journalists have also made it their mandate to enable the flow of information between the residents and the local authority. In terms of sourcing there is a deliberate stance to include those who are not ordinarily given a voice in the mainstream media. Women and the poor appear frequently in stories as sources and this is a different scenario from that prevalent in mainstream journalism which frequently covers the rich and the powerful. The citizen journalists in the Iindaba Ziyafika project have also borrowed practices from professional journalism and this has been integrated into their daily practice. This includes following strategic rituals of journalism objectivity and balance.

  • Description: Today‘s customers expect zero defects with just-in-time (JIT) delivery from their suppliers, for the specified quantities, as a matter of standard practice. More importantly, customers expect companies to help them know what they need in terms of quantities and quality now, and for the future. No other change process adds long-term value as quickly as zero defects. Companies failing to embrace this quality culture face difficult challenges. To achieve this level of performance requires tremendous focus in an organisation and throughout its supply base. Business models around the world are changing dramatically from the "Source Local" to the "Source Anywhere and Build Anywhere" model (Cummins, 2008: 19). Companies have shifted away from a hierarchical, one-dimensional, supply chain entity to a fragmented network in favor of strategic partnerships with external entities. Many businesses facing such models are experiencing challenges and, if not managed correctly, can find themselves struggling to compete in this new landscape. Thus, when price concessions are so stringent, quality has to suffer. To reduce costs, suppliers are forced to seek less expensive ways to produce parts and components. Does this mean the use of different, less expensive materials? Does this mean less skilled labor? Does this mean production shortcuts? Or does this mean that suppliers just bite the bullet and pay the price? Once all the costs have been extracted from the supply chain, the only thing left to suffer is quality. The underlying objective of this research is to investigate the impact of delivery performance for a selected part at General Motors South Africa. In order to develop a research strategy to deal with, and solve, the main problem, the following research questions have been identified: a) What can be learned from literature about the impact of quality costs? b) Why is this specific part a suitable candidate for a cost investigation? c) What are the processes involved if a defect occurs? d) How can the cost be estimated? e) What effect does poor supplier quality have on productivity? This dissertation aims to investigate the problems and challenges General Motors South Africa are facing pertaining to the delivery performance of a selected part. The dissertation will also strive to highlight the impact of poor supplier quality on productivity and the related cost implications. Conclusions and recommendations will furthermore be outlined.

  • Description: This study focused on assessing the condition and creating a carbon inventory of forests in the Matiwane area of the Transkei. This entailed the use of aerial photography in tracing forest cover change from 1942 to 2007 coupled with ground-truthing to assess whether the forests have in any way endured degradation over the years with a potential reduction in carbon stocks as a result. This study revealed both the loss and gain of biomass in the area with a general trend of forests being continuously converted to agricultural fields resulting in reduced forest area, stem density, tree density and carbon loss in different pools of the forests, reflecting that these forests are degraded. The conversion has resulted in the reduction in the number of species from a mean of 11±0.57 species/200m² in intact forests to 1±0.23species/200m² plot in degraded forests. It was also revealed that approximately 5.2 % (791 hectares) of 15 352 hectares of forest area was lost as a result of the conversion of forest land to agricultural fields from 1942 to 2007 with 99 % of the clearing occurring in the last 33 years (1974-2007) and of which 60 % ( 4 77 hectares) occurred from 1995 to 2007, indicating that forest degradation in these forests is on the increase. The assessment also revealed some areas that were nonforest in 1942 that have accumulated woody biomass (BAA), composed mainly of Acacia sp accounting for 51.18 MgC.ha⁻¹ (Megagrams of carbon per hectare) and total carbon stocks of 0.02 TgC (Teragrams of carbon). The degradation of these forests induced a reduction in carbon stocks from 311.68±23.69 MgC.ha⁻¹ (to a soil depth 0-50 cm) in intact forest to 73.46±12.34 MgC.ha⁻¹ in degraded forests. The total carbon stocks in the degraded forests were approximated at 0.06 TgC and the BAA areas 0.02 TgC with 4.7 TgC in intact forests. The degradation of these forests has resulted in the net carbon loss of 0.19 TgC between 1942 and 2007 but 4.76 TgC is still locked in these forests. The large difference in carbon stocks between intact and degraded forests indicated the need to reduce the degradation of these forests to prevent further carbon loss and reduction of the carbon sequestration potential of these forests.

  • Description: The aim of this descriptive study was to explore the impact of HIV/AIDS on the maternal health programme at selected Primary Health Care (PHC) clinics in the Peddie sub-district, in the Eastern Cape, South Africa. This study showed that the HIV/AIDS epidemic has had major influences on the rendering of maternal health services in this sub-district. An understanding of the impact of HIV/AIDS on the delivery of the maternal health programme in the Peddie Primary Health Clinics will potentially help the District Health Service office, as well as the clinic managers and professional nurses to formulate strategies to strengthen the maternal health programme. This data will also be helpful when developing plans to cope with the heavy work-load of the clinics offering maternal health services, and to address the attitudes and concerns of the professional nurses working in the PHC clinics in this area. Thirty professional nurses working at 10 clinics responded to the questionnaires which elicited questions pertaining to the impact of HIV/AIDS on the rendering of their services. As part of the data gathering procedures, standardised notice boards at the PHC clinics were used to document the services rendered. The numbers of ANC clients attended to each of the clinics per week were collected in routine attendance tick registers used in the clinics for recording and monitoring statistics in the maternal health programme. The data was analysed to examine the possible impact of HIV/AIDS on maternal health services rendered by registered nurses/midwives working in the PHC clinics. The registered nurses who responded to the questionnaires (Annexure H) made several suggestions. These included the following: (i) encouraged more training (11 nurses), (ii) addition of more staff members, (iii) to have specialized staff for management of maternal HIV. Because of the study limitations such as the sample size of 10 clinics with a total of 30 nurses who were studied, the study may not be generalised to the whole of the Eastern Cape Province. The study however did provide baseline information on the impact of HIV/AIDS on the maternal health programme. The study findings were that HIV/AIDS has had an impact on the delivery of the maternal health programme due to the extra services brought about by the response to the HIV/AIDS pandemic. This study will contribute to a better understanding of the impact of HIV/AIDS on the maternal health programme at the PHC level in Peddie. The research provided insight into issues that are crucial to the delivery of maternal health programmes in rural areas. , Thesis (MCur) -- Faculty of Science and Agriculture, 2011

  • Description: The aim of this study was to investigate the impact of Human Resource Management (HRM) practices on the psychological contracts of employees who have been negatively impacted by the widespread psychological recession. The psychological contract that exists between employees and organisations is brittle due to the psychological recession, which is defined as an emotional state in which employees feel extremely vulnerable to economic hardship. This contributes to a negative and cynical view of the present and an even bleaker view of the future. Breach of the psychological contract has severe negative consequences for employees and organisations. These include reduced employee well-being, trust levels, various organisational citizenship behaviours, increased cynical attitudes toward the organisation, and stronger intention to quit. The target population for the present study consisted of all permanent support staff working at an organisation that has recently went through a large-scale retrenchment exercise (n=52). A self-administered questionnaire was distributed amongst employees. The findings suggest that when the harsh effects of the psychological recession increase, employees are more likely to engage in various destructive behaviours at work due to breach and violation of their psychological contracts. Furthermore, the results indicated that an increase in the number of progressive HRM practices correlated with a decrease in breach and violation of the psychological contract. It was further revealed that the widespread psychological recession may make the employment relationship brittle and prone to breach and violation. The findings suggest that through the effective development and application of many explicit HRM practices, employees’ psychological contracts may become less fragile to breach and violation during a psychological recession.

  • Description: Today‘s workforce consists of employees with diverse personalities, cultural backgrounds, nationalities, needs and wants, thus creating new challenges for today‘s leaders. One of the primary functions of leadership is the management of employee perceptions that influence organisational outcomes. Among these perceptions the perception of politics is an influential type of organisational phenomenon. There is no denying the fact that leadership greatly affects the performance of organisations. According to DuBrin (2010:8), an overview of research on managerial succession conducted over a 20 year period provides support that leadership has an impact on organisational performance. The analysis of the research found that leaders might be responsible for somewhere between 15 per cent and 45 per cent of a firm‘s performance. From the above mentioned research, it can be seen that the importance of leadership cannot be underestimated when regulating the effect of politics in the working environment and to achieve the company goals and objectives. Part of the challenge today‘s leaders face is to help employees to see the different perspectives of political actions as a positive force, rather than seeing these as negative processes that cause internal competition for resources, recognition and promotions. Company politics does not have to be about back stabbing, internal rivalry, manipulation for power and lack of trust. With the development of proper skills and personal and organisational goals, positive organisational politics provides the real foundation for competitive advantage to benefit the employee as well as the organisation. The main purpose of this research paper is to identify the influence of leadership on organisational politics. The first step was to complete a literature study on the iii selected factors which contribute to organisational politics. The factors selected were those of job ambiguity, scarcity of resources, personality, uncertainty and fairness. The literature study also includes the outcomes of organisational politics. These outcomes include job satisfaction, job performance, turnover intention and job stress. An empirical study was then used to analyse the views of staff in various departments. These questions were based on the selected factors mentioned in the previous paragraph. This involved the staff completing questionnaires. Based on the findings of the literature study and the empirical study, the last step is to make recommendations to the selected company on managing the perceptions of organisational politics. Recommendations are also made as to what leadership styles would best fit different situations

  • Description: The merger of higher institutions in South Africa after 1994 was an important change seen by the ANC-led government to break the shackles of the apartheid era. Notwithstanding the many positives that resulted from these mergers a lot of problems were experienced. This research study sets out to investigate the impact of mergers on managers and educators in the Buffalo City Public FET College (BCC) in East London in the Eastern Cape Province. The purpose of the study was to establish whether the working conditions of managers and educators at BCC had improved and whether managers and educators of the Public FET Colleges were able to interpret the FET Act, No. 16 of 2006 properly in order to improve the operational functions of the BCC. It tried to establish what measures were taken to assist managers and educators to improve the participatory decision-making within the structure of management of the college and whether the merger had any influence on the existing human relationship between staff members from different colleges. To this end an exhaustive literature review was conducted looking at an international perspective as well as a national perspective. The empirical design was a case study which made use of structured interviews to collect data from the three satellite campuses of BCC, using managers and educators. Emerging from the case study was that the merger policies within the FET sector have not properly addressed what might be the issues which would be expected to be achieved. The FET Act, Act No. 16 of 2006 affects the operational functions of the college in such a manner that some educators decided not to transfer their services to the College Council. There was a contradiction in terms of accountability, in the sense that when the employees had grievances the Provincial Department of Education referred the matter to the College Council and the College Council referred back to the Provincial Department of Education. It seemed that nobody would like to deal with the challenges of the college. Most of the participants expressed their dissatisfaction that principals and senior managers were remained employees of the Department of Education, while they, the educators, were classified as employees of the College Council. As far as the conditions of service were concerned, the participants mentioned that the qualified educators were not interested to join the FET College sector because of the salary structure; instead they opted to join the industrial sector where they received better salaries and conditions of service than at the college. Based on the findings emerging from the literature and case study it was recommended that the college must formulate credible policies for effective and efficient operations. A committee should be established to deal with fund-raising. The college must be given a chance to govern their affairs (autonomous status) as the FET Act, Act No. 16 of 2006 stipulates very clearly. Transparency in operational issues was seen as an important prerequisite. Transparency in Public FET Colleges means handling matters in such a manner that such as done openly either in the presence of all affected parties or allowing such parties to demand explanations or documentation or both.

  • Description: The small, medium and micro-enterprise sector is recognised as being favourable to socioeconomic growth since SMMEs have capacity to generate jobs. SMMEs are particularly beneficial for previously disadvantaged communities, and it is particularly clear that SMMEs play a critical role in economic development. It is therefore important to encourage growth of this sector by introducing a favourable and a conducive environment for the sustainability of the SMMEs. The purpose of this study was to investigate the impact of regulatory compliance on SMMEs in the Buffalo City municipal area in South Africa’s Eastern Cape Province. In other words, this study seeks to find out how SMMEs in the Buffalo City experience regulatory compliance. Exploratory quantitative and qualitative research methodologies were used in this study. In this instance structured questionnaires were used to collect data. In order to provide a precise presentation of information, face-to-face interviews with the SMME owners were conducted. The results of this study indicate that the regulatory environment within which the SMMEs operate is not a constraining one. Although the manual registering process is reported to take long, the electronic or online business registration is much quicker. Notwithstanding, the business registration agencies were reported not be too easily and readily available and accessible. In terms of labour regulations SMME owners and managers indicated that compliance with labour legislation in terms of health and safety was benefiting to their businesses as they learnt how to develop polices and plans. Although the regulatory environment of the SMMEs is not a constraining one, there are costs involved. For example the respondents indicated that the labour laws increased their operating costs. In accordance with labour legislation, employees are entitled to all kinds of paid leave such as annual leave, maternity leave and sometimes study leave; needless to say a right to strike. The labour law regulations were seen to be time consuming and presented an administrative burden for managers. With regards to tax regulations compliance, there was an indication that due to the extra efforts taken by SARS, it was easy to comply. The SMMEs were exposed to what is required in order to comply fully with tax laws. Some respondents mentioned that they lacked the facilities to deal with VAT issues. The study recommends that government should ensure that the registration costs of small businesses remain low and that the turnaround time for registration is shortened. The support structures which are to assist small businesses need to be mentioned in all the media for everyone to be aware of them including the rural areas. The government needs to educate SMME owners and managers on how labour laws can benefit small businesses. Also the business registration process should be streamlined and linked with the South African Revenue Services in order for a ‘one shop stop’, so to shorten the time during formalisation and registration processes. It is also recommended that the South African Revenue Services together with the government simplify the tax issues applying to SMMEs further more especially Value Added Tax which seems not to be easily understood. This will in turn assist SMME owners as they will know more about tax issues, they will also know more how to handle them which should in turn lower the costs of doing business.

  • Description: Technology and the boom of the internet have encouraged people to connect with each other, share information and build relationships (Stelzner, 2009; 2010) and the social web has presented a new form of communication through social media which allow people to interact and converse with each other (Evans, 2010). This presents marketers with the opportunity to affect consumers purchase decisions through online marketing and social media. This social engagement by consumers has significant impact on marketing activities as marketers need to be aware of the factors affecting consumer’s purchase decision (Evans, 2010). Continental Tyre South Africa (CTSA), a local tyre manufacturer, is embarking on a social media marketing strategy. No other local tyre manufacturer has a presence on social media platforms. As a result CTSA would have first mover advantage. The main objective of the research that follows is to establish if South African tyre purchasers are supportive of social media as an online research tool to learn more about tyre brands. The significance of this research study is that marketing communications has taken on a different dimension with the growth of online market places and the natural step for CTSA is to engage in social media marketing. The literature review revealed that many modern consumers sought peer advice over social networks thus social media has promoted consumer-to-consumer communication and has made it possible for consumers and brands to interact with each other (Mangold and Faulds, 2009). It was concluded that whilst social media marketing presents marketers with a more cost effective form of marketing, further research regarding South African’s online purchasing activities would be required to assess if the time, money and resources required to manage social media marketing for CTSA would be beneficial to the organisation. As a result a qualitative empirical study was conducted by means of a questionnaire. The research elements were broken down into three segments; the internet and social media, consumer-brand engagement and online iv recommendations. The research revealed that social media marketing is an appropriate strategy for CTSA. The main findings further revealed that CTSA would need to engage in an aggressive traditional marketing campaign in order to drive consumers to engage in the social media campaigns. Strategies must include dedicated social media fan pages, online banners, and online advertisements. Based on the research analysis it is recommended that that most appropriate social media platforms for CTSA to launch social media marketing activities are Facebook and Twitter.

  • Description: The purpose of the research was to improve the use of electronic human resource management in South African businesses by investigating that there is a positive impact when implementing e-HRM on the human resource management function. The research was carried out within a South African business, whose parent business concern is based overseas and has branches operating within South Africa The research was significant as it shaped the researcher’s concern as to whether electronic human resource would be beneficial to a South African business if the business superiors decide to implement e-HRM within their business opinion and what impact it would have. The methodological components that guided the research were a structured questionnaire that was distributed by using a combination of convenience, snowball, and judgemental sampling techniques. Certain aspects highlighted in the literature review were used as the framework for the development of a questionnaire to assess how people perceive the implementation of e-HR on their working environment and if e-HR has helped the business run more efficiently and effectively. Six hypotheses were tested and all were accepted. The potential for generalisations of the findings are that given the potential that e-HRM has for the transformation of human resource, it is reasonable to expect that the sizeable changes required, both in organisation and mindset, are likely to provoke resistance from various end users. What was learned was that HR is often hindered by a multitude of manual, paper based processes and transactions, such as tax, payroll and benefits information, that are costly, prone to errors and time-consuming to manage. This makes it difficult for HR organisations to focus on higher value business in initiatives that may help to drive the profitability and efficiency of the organisations. The implication of the findings about the impact of the implementation of e-HR on the Human Resource Management function was that firms need to figure out how to make technology feasible and industrious, as managers and Human Resource professionals are responsible for redefining how work at their firms or business flow as they need to keep ahead of the information curve and therefore learn how to influence information for business results to be more efficient and effective. The theoretical and practical implications of the findings are discussed and recommendations based on these findings are provided.

The reason for this is that South African listed companies declaring local dividends will not necessarily have all the details of and know the identity of their shareholders. These financial institutions may be regarded as regulated intermediaries in terms of the new Dividends Tax legislation and therefore may have the responsibility of withholding the Dividends Tax from dividends received on behalf of their clients, who may in most cases be the beneficial owners of the underlying equity shares. The motivating factor for the research is the fact that there does not appear to be any guidance on the impact of the new Dividends Tax on financial institutions, since the Dividends Tax is new legislation. The research problem addressed in this thesis is how the systems and processes of a financial institution will be affected by the implementation of the new Dividends Tax. The research took the form of a case study designed to investigate the impact of the Dividends Tax on the financial institution at which the researcher is employed. The data required for the research was collected by means of a study of the relevant legislation enacted in connection with the topic, journal articles in financial/tax journals, as well as articles published in the media. The systems and processes presently in place, as well as the changes to these systems that will be needed to accommodate the new dividend tax were ascertained by means of in-depth interviews with relevant staff at the financial institution. In addition, the researcher also applied her personal knowledge of the business of the financial institution at which she works to the problem. As a result of the research it was determined that a Collective Investment Scheme, Linked Investment Service Provider and Long-Term Insurer will all be regarded as regulated intermediaries for the purposes of the new dividend withholding tax. This means that these financial institutions will be required to withhold Dividends Tax from dividends paid to their clients and pay this Dividends Tax so withheld to SARS. Furthermore, the findings of the research confirmed that the new Dividends Tax will have a significant impact on the client services department in areas such as notifying clients, training of client service staff, handling of declaration of exemption forms received from clients, amending client statements and tax certificates (to cater for the new Dividends Tax). In addition to this, it was ascertained that significant systems development will be required by these financial institutions in order to comply with the new Dividends Tax legislation. This would include the development of data input fields to enable users to capture the relevant information required and development of the system to enable it to flag local dividends received to which the Dividends Tax applies. The system would also need to cater for Secondary Tax on Companies credits as well as foreign tax rebates. The system should also be able to calculate the amount of Dividends Tax to withhold per dividend received by a client, as well as be able to handle the payment of the Dividends Tax to SARS and the refund to clients of Dividends Tax over deducted. It is essential that systems are able to flag the correct date of payment of the dividend so that the Dividends Tax can be paid over timeously to SARS in order to avoid interest and penalties being levied. To summarise, the new Dividends Tax has a significant impact on these financial institutions in areas such as client services, administration and system development.

  • Description: In this study toys were used as educative curriculum material in an intervention on the topic of energy aimed at Intermediate Phase pre-service science teachers (n= 87) registered for a BEd degree at the Nelson Mandela Metropolitan University, South Africa. The intervention consisted of, amongst other elements, lectures, assignments and toy workshops, with the latter being a key driver in the process. The choice of toys as the educative curriculum material was informed by the fact that there is a huge variety of simple, reasonably priced and easily procured toys that are suitable to demonstrate the concept of energy from both theoretical and practical perspectives. The conclusions that can be drawn from the study are that the use of toys in the preparation of pre-service primary school teachers has the potential to substantially improve their subject content knowledge (SCK), pedagogical content knowledge (PCK), and their confidence related to these two constructs with respect to their understandings of energy. The data generated also suggest that when appropriate educative curriculum materials are integrated into a topic in science-teacher education, there may be a substantial positive impact on pre-service teachers‘ confidence in both their understanding of the science content and their perceptions of their ability to teach this content. An additional finding of the study was that, despite its popularity, status and usefulness over many years, the Science Teacher Efficacy Belief Instrument (STEBI-B) shows low sensitivity to measuring changes in efficacy as a consequence of the so-called ‗ceiling effect‘. The ceiling effect is a result of initial high scores which provide little opportunity to show iii substantial positive change as a result of an appropriate intervention that is designed to improve efficacy. While this study did not directly address this lacuna in STEBI-B, it made use of an innovative descriptive statistic, ‗percentage gain of potential‘, in an attempt to describe and interpret even small changes in efficacy as measured by STEBI-B.

The impact on the family dynamic of having a child and sibling with Down syndrome

  • Description: The raison d'être of my research is simple: it’s about tossing one more starfish back into the surf. Down syndrome is not a disease, nor is it contagious or a death sentence (it only feels that way when you find out for the first time). At the moment of conception, the apprearance of extra genetic material results in a total of 47 chromosomes in every cell. Usually each cell has only 46, thus making an individual with Down syndrome far more like others than different from them. Yet, this extra chromosome presents special circumstances regarding their ability to acquire new skills, be it academic or practical, encompassing a specific learning profile with typical characterisitcs, strengths and weaknesses. Twenty-first century family life is simultaneously challenging and richly rewarding and the expectancy of most families are of a life lived on paved highways with well-marked signs, and rest stops never far apart. Adding an extra chromosome to the luggage sends the family travelling down a vastly different highway instead, not always knowing what is ahead. It’s scary, but in reality even those on the wide smooth roads do not know the future. Echoing the feelings of many parents, Leonard (1992: 5) states, “The trouble is that we have few, if any maps to guide us on the journey or show us how to find the path…” Assumptions from previous decades that used to increase stress associated with rearing a child with Down syndrome would negatively impact on individual family members and the family unit as such. This has made way for the growing consensus that it is not necessarily the norm. Whilst some families have trouble in adapting to the increased stress, other families adjust easier and even thrive. Successful adaptation seems more likely in resilient families who enjoy high levels of parental well-being and strong relationship bonds. Findings of this qualitative research study confirm that unresolved marital strains are more likely to result in divorce as opposed to the birth of their child with Down syndrome. Correspondingly, siblings of children with Down syndrome reported mostly positive impact than negated opportunities to participate in a normal childhood. My motivation for this research was to explore the nature of challenges faced by modern families and to provide mechanisms to facilitate positive adaptation for the family and aid vii inclusion of the child with Down syndrome into school and greater society. Recommendations are also presented for the medical professionals who, ironically, have proved to be the last people parents want to go for support, owing mostly to their decidedly objectionable treatment of parents; as well as the generally uninformed public, who seldom understand or support attempts of parents to include and expose their child to everyday experiences. In conclusion, I summarize: Should it be that I may influence but one person to see persons with Down syndrome for the potential that they hold instead of the associated problems of their condition, this would afford me the satisfaction and contentment knowing that I have succeeded in making a positive contribution to their plight. I would have successfully portrayed the families for the ordinary people they are with anticipations, aspirations and anxieties, but later tasting the elation of being empowered, and the resultant enjoyment and pride of the achievements of their extraordinary “starfish” child. The simple story below explains it all. A little boy was walking on the beach when he noticed scores of starfish washed onto the beach by the previous night’s high tide. He curiously watched as an old man bent down, came up slowly and tossed one starfish after the other into the surf. He went closer to investigate. “Excuse me, sir, what are you doing?” he enquired. The old man said: “I am throwing the starfish back into the ocean before they die, my boy…come, lend a hand”. The boy looked up and down the beach at the hundreds of starfish scattered along the shoreline. “But there’s too many…” said the boy, “it’ll make no difference!” The old man smiled, bent down, picked up another starfish, and carefully tossing it into the clear blue water, he replied, “…It makes a difference to this one…”

  • Description: The project describes the action research implementation, and evaluation of learning, of a service-learning component in a second year undergraduate organic chemistry course. The research aims to explore the learning that takes place in a service-learning context while utilizing an action research methodology within the critical theory paradigm. This occurs in response to the world-wide call for Higher Education to produce people with civic competencies and responsiveness to the society in which they live (Boyer 1996). Educating young Chemists to see the importance of their knowledge and their responsibilities in society is an important pedagogical step in the effort to cross boundaries and make connections between people communities (Eyler and Giles 1999). The goal of this project was to explore and categorize the learning that takes place in a service-learning context and discover how these areas of learning impact the awareness of the parties involved with regard to the discipline of chemistry as well as social issues. The project makes use of Kolb‘s (1984) Experiential Learning Theory, and Eyler and Giles‘ (1999) categories of learning in service-learning and results indicate that service-learning can be a powerful pedagogical tool to increase learning in chemistry as well as in the areas of critical thinking, personal and social development, reflection and citizenship. Students‘ perceptions of themselves, their discipline and their responsibility to society were transformed by their experience of service-learning in their undergraduate chemistry course.

  • Description: This document consists of three sections, and they are the academic paper (section 1), literature review (section 2) and research methodology (section 3). The academic paper consists of the purpose of the research, the summarised literature review, summarised research methodology and the research findings. The literature review section is a detailed review of literature used in this study. The research methodology section explains the research methodology and design which was employed in this study and it gives more details than the summarised version of the academic paper section. This summary integrated all the elements of section 1, section 2 and section 3. The purpose of this research is to identify the main problems that the Department of Environment and Nature Conservation (DENC) could encounter during the implementation and use of a performance management system, based on employee perspectives. The objectives of this research are therefore: to establish how often a particular problem has been encountered during the implementation and use of a performance management system in DENC; to identify the impact of various problems on the implementation of a performance management system, to establish whether these problems can be easily solved or not, and to analyse the problems associated with the implementation of a performance management system, as well as making recommendations for the successful implementation of a performance management system in the future. In this study, the researcher employed both quantitative and qualitative research approaches, informed by post-positivism as research orientation. The data collection techniques employed in this research include survey questionnaires and individual interviews. The survey questionnaire was answered by fifty respondents, and interview questions were answered by four respondents. The ethical issues were addressed by writing a letter to the Head of Department and getting authorisation to complete the research and informing respondents of their right to withdraw and to participate voluntarily. The findings indicate that the problems are either sometimes encountered or rarely encountered, and the division is about fifty percent of those sometimes encountered to those rarely encountered. This research indicates that most of the problems have a moderate impact on the use and implementation of a performance management system. The lack of management has a high impact, and a lack of positive attitude to performance management system (PMS) certainly has an impact on the use and implementation of the performance management system. Items such as the problem of information and communication technology (ICT) which does not support PMS adequately, and defining too many key performance indicators (KPI), have a small impact on the use and implementation of the performance management system. There are three problems which are difficult to solve and they are: lack of management commitment, organisational members‟ lack of positive attitude to the PMS and an insufficient period of commitment from management to PMS. This research indicates that most of the problems associated with PMS are moderately easy to solve. Two other problems that are easy to solve include the problem where there are too many KPIs defined and the problem where there is no organisational member appointed to take ownership of the PMS. According to this research, the top ten ranking problems have high ranking scores and this indicates that they can create major difficulties for the DENC in implementing the performance management system, and the chance of encountering these problems is high in the DENC in comparison to other problems. Almost all the problems ranked in the top ten seem to score highly in terms of the severity of their impact, and therefore this means that these are the problems which have an impact and, when they are not easily solved, they can become a tenacious issue for the organisation.

  • Description: Inherent to post‐apartheid educational transformation was the design and subsequent implementation of a new national school curriculum. The current curriculum‐in‐use, namely the National Curriculum Statement (NCS) comprises eight compulsory learning areas. One of these learning areas, Arts and Culture, aims to equip learners with skills and knowledge with regard to four distinct arts disciplines, namely music, dance, drama and visual art. In the General Education and Training Band (GET) phase, general classroom teachers are expected to implement this highly specialised learning area. This research aimed to determine how teachers employed at Nelson Mandela Bay primary schools were disadvantaged during the apartheid era, experience the implementation of arts education. Focus group interviews were conducted at schools situated in the low socio‐economic areas. The results revealed that, despite their profound awareness of the unique advantages of arts education for the learners, several impediments hampered the successful attainment of its value. The obstacles highlighted by the teachers were the curriculum itself, teaching and learning environments that are not conducive for arts education, and unsatisfactory involvement of the Department of Education.

The implementation of the right to education in South Africa and Nigeria

  • Description: The thesis examines the right to education in South Africa and Nigeria. It presents the right to education as an empowerment right which is given a wide recognition in a number of important international and regional human rights instruments as well as in national constitutions. It asserts that the right to education is a right with a multiplying effect in the sense that where it is effectively guaranteed, it enhances the enjoyment of all other rights and freedoms, and when it is denied, it precludes the enjoyment of many other human rights. The thesis examines the provisions of relevant international and regional human rights instruments to assess the adequacy of a framework that applies to South Africa and Nigeria's obligations regarding the right to education. It argues that those instruments impose obligations on all the States to make primary, secondary and higher levels of education available, accessible, acceptable and adaptable to all in their territories. It argues that by having ratified those international agreements in which the right to education is protected, both South Africa and Nigeria assume obligations under international law, enjoining them to realise the right to education and to respect freedoms in education. The study adopts a comparative approach and relies on primary and secondary sources of data; the data is subjected to an in-depth content analysis. The focus of the comparison is on whether the South African's position regarding the right to education can inform Nigeria's interpretation of the right to education. The reason being that the Nigerian Constitution does not provide for the right to education as a basic right as exists in South Africa. The Nigerian Constitution categorised the right to education under “fundamental objectives and directive principles” which are non-justiciable. In this sense, the thesis argues that the legal classification of the right to education, to a large extent, affects its realisation in Nigeria. It suggests that an important area where Nigeria could learn from South Africa is the issue of justiciability and constitutionalising the right to education as well as other socio-economic rights. In terms of implementation, the thesis submits that despite the international obligations and commitments to provide education for all, there is a significant gap between what is stipulated and the practical realities in the two countries. It argues that the right to education is more than a mere school attendance, how well a learner progresses in school is equally important. It posits that the high failure rates and the progressive slide in students' performances in schools xx examinations as shown in the study illustrate the poor quality and falling standard of education in the two countries. South Africa enjoys one of the highest rates of formal school enrolment of any developing country, yet the link between access and success is also weak in the South African schools just as in Nigerian schools. Inadequate planning, poor implementation of policies, lack of adequate resources and commitments are identified as the prime factors hampering the implementation of the right to education in both countries. Solving these problems and making the right to education realisable call for a renewed government commitments and investment of appropriate human and financial resources on education. This also requires a strong political will as well as concerted efforts of all the various actors in the educational sector in the two countries.

  • Description: Photography has been used to record and document periods in time, which Wells (2001:19) acknowledges by stating that, “…photographs are records and documents which pin down the changing world of appearance”. Richard Avedon and Irving Penn made a significant contribution to fashion photography during the 1950s but this has seldom been explored in a scholarly way. By defining the characteristics of Avedon and Penn’s work, a possible understanding of their influence on contemporary fashion photographers, Matthew Rolston and Steven Meisel may be determined and so expand on the understanding of the contribution of Avedon and Penn to contemporary fashion photography. Avedon, Penn, Rolston and Meisel’s fashion photographs will be visually analysed to show the similarities and the relevance of 1950s fashion photography to contemporary fashion photography. Paul Martin Lester’s (2003) method of visual analysis will be used as the basis for this analysis. The reason for choosing Lester’s methods of visual analysis is that it can be applied to all fields of visual art and design. Contemporary fashion photography draws on many different stylistic devices and periods in history for its re-invention, so it is important to understand what constitutes the defining characteristics of a stylistic period in history to be able to revisit it in contemporary photography.
