- Description: Inclusive Education (IE) reflects the values, ethos, and culture of an education system committed to excellence by promoting education opportunities for all learners. IE is about building a more just society and ensuring the right to education for all learners regardless of their individual characteristics or difficulties (UNESCO: 2007). The kingdom of Swaziland has committed itself to high quality basic education which provides equal opportunities for all children and youth. This is evident in the Swaziland National Constitution (2006). To promote Education for All (EFA) as stated in the constitution, an IE Policy has been developed and a draft policy is in place. The programme has been operational since 2006. There are nine pilot schools and four teachers from each school who have been trained on how to handle pupils with disabilities. The programme will be rolled out to 608 primary schools by 2015. In this research, the goal was to investigate how a School Management Board responds to the challenges of managing an Inclusive School. This research is a qualitative interpretive case study based in one of the pilot schools in Mbabane in Swaziland. The study used document analysis, semi‐structured interviews and focus groups to collect data. The study revealed that the school has done much in accommodating IE as there are changes in management structures and approaches, organizational culture and operating procedures. On the other hand, there are still significant challenges such as a lack of knowledge of inclusion and negativity on the part of learners and parents. Other challenges include inadequate training for educators and lack of suitable infrastructure. The study concludes by recommending improved staff development programmes, infrastructure upgrades, acquiring appropriate teaching and learning resources and employing multidisciplinary personnel.

- Description: This study considers the nature of savings behaviour amongst low income earners residing in the township areas of Kouga Municipal District. It reflects on the popularity and persistence of informal savings and credit associations, also known as stokvels, in these communities in the face of an increase in the availability of formal savings products. This study argues that despite financial deepening taking place within the South African economy, the popularity and widespread usage of stokvels can largely be attributed to the lack of appropraite formal products available for low income earners. This study does not conclude that the usage of informal savings products results in increased savings behaviours amongst this group, but it does conclude that they provide a suitable mechanism in which savings can take place.

The valuation of amounts for the purpose of inclusion in gross income

- Description: The present research investigates the valuation of amounts for the purpose of inclusion in gross income. Because the gross income definition in section 1 of the Income Tax Act includes "amounts in cash or otherwise", valuations are often required in order to establish a value in money terms for amounts received or accrued in a form otherwise than in cash. The basis on which these valuations are made can vary and the courts have frequently been called upon to decide on the correct method of valuation. There has been an ongoing debate in the courts as to whether a strict objective approach or a more flexible subjective approach should be adopted when valuing an amount in a form other than cash, which was finally settled in the decision by the Supreme Court of Appeal in CIR v Brummeria Renaissance (Pty) Ltd, which held that an objective approach must be followed. The present research will demonstrate how the strict rule of interpretation tends to result in purely objective valuations as it requires that the ordinary grammatical meaning of words be applied and does not allow the court to consider the purpose of the legislation or introduce any subjectivity based on the circumstances of each individual taxpayer and the facts of each particular case, which a purposive interpretation approach does. The purposive approach to interpretation is therefore more closely aligned with the subjective approach to valuation. Both the objective and subjective approaches to valuation have advantages and disadvantages, which are addressed in the research. The need for certainty in taxation was articulated as early as 1776 by Adam Smith in his Wealth of Nations. The objective approach appears to create a level of consistency as all income received by a taxpayer is effectively taxed as if received by a third party in an arm’s length transaction. The approach has led to unfair decisions at odds with economic reality and generally accepted accounting principles, which could be challenged on the basis of a lack of equity and fairness as required by the Constitution of the Republic of South Africa. The research demonstrates that an objective method of valuation is neither fully objective nor appropriate in certain circumstances, while a subjective approach may be more appropriate as it ensures that each taxpayer’s individual rights are protected. Although the subjective approach successfully addresses the issue of fairness, it threatens to introduce an unacceptable level of inconsistency and is, in reality, not always administratively feasible. The present research concludes that a trade-off between fairness and consistency is often necessary.

- Description: The problem of school under-performance as defined by the level of pass rates of learners in the matric examinations has been a point of educational debate in South Africa for a number of years, especially after the attainment of democracy. In the Eastern Cape, Matric Intervention Strategies (MIS) have been used to address the problem. The aim of this study was to investigate educator perceptions of the impact of the MIS on selected under-performing high schools in the Queenstown District.Two case study schools classified as consistent under-performers participated in the study. Data was collected through in-depth interviews of key educators in these schools. There were five main findings. First, educators felt that Departmental intervention strategies had not made any significant improvement in addressing underperformance in the two case study schools. Second, participants saw underperformance by schools as caused by a myriad of factors which include those related to leadership and management at school and district levels and educator and learner factors, as well as teacher union interference. They did not see MIS as being able to address the causes simultaneously. Third, the implementation of the (MIS) at school level was poorly monitored by the Departmental officials. It was reported that under-performing schools were hardly visited and supported by the subject advisors and (MIO)s. Fourth, educators perceived the role of subject advisors to be limited to CASS moderation as they did not provide any developmental support to educators experiencing content gaps. Finally, educators saw the MIS as a money making scheme for certain educators and district officials. They claimed this was linked to corrupt practices during the appointment of tutors. The teachers did not have confidence in the appointment procedures used by the district for tutors.It can be concluded that the Matric Intervention Strategies in the two schools arenot likely to achieve the intended results as long as educators do not think thatthe strategies are addressing the problems they face. Another conclusion is that the Matric Intervention Strategies are seen as ‘quick fix’ responses to what arereally deep-seated and systemic problems in education. Given the findings of this study, it is recommended that the impact of Matric Intervention Strategies be the focus of a survey research for which a probability sample must be drawn that can generate findings that are generalisable across the participating target population. For the delivery of the MIS it is recommended that the weaknesses identified by educators of the two schools be further investigated so that new implementation plans can be developed.

- Description: This study intends to explore how social media or social networking sites (SNSs) such as Facebook can facilitate communication channels or create dialogue spaces in a language class. Social media is a form of participatory media, which broadly refers to the “collection of communication channels or mediums (primarily online and mobile) through which social networks originate and are sustained” (Flew 2008:109). Although the term social media is often used as a collective term for SNSs or as the core trademark of Web 2.0, Flew (2008:17) also distinguishes social media by calling it a “communications infrastructure” that allows for “participation, interactivity, collaborative learning and social networking”. Flew (2008) identifies various online sites including the online encyclopaedia Wikipedia and the online user-generated video site YouTube as well as various personalised web space sites such as MySpace, Facebook, Friendster and Bebo as participatory media. The study’s data collection was situated at Nelson Mandela Metropolitan University (NMMU) and investigated how social media can be used to facilitate dialogue between a tutor and BKI1120 Communication in English B students in a Higher Education (HE) context using qualitative methodology. This study compared the use of existing and more traditional or conventional classroom communication practices with those of SNSs as a communication channel, while focusing on social media application as a communication tool to create dialogue spaces that support teaching and learning practices. The research also attempted to identify alternative applications of social media for teaching and learning practices to inform researchers in the fields of HE and media. In the first data-collection phase, BKI1120 Communication in English B Public Management students were selected as the sample for the study. Seventeen students participated in the BKI1120 Facebook page created for the purpose of this study. In the second data-collection phase, a taped focus-group interview was conducted with eight BKI1120 Communication in English B students. The interview transcript was then analysed qualitatively for themes. The research findings showed that social media or SNSs such as Facebook can facilitate communication channels or create dialogue spaces in a language class, if it is managed effectively.

Dreams, sexuality and fantasy: a psychoanalytic reading of K. Sello Duiker’s novels

- Description: The primary aim of this thesis is to provide a text-based literary study exploring the characters and themes created by K. Sello Duiker in the three novels, Thirteen Cents, The Quiet Violence of Dreams and The Hidden Star. Duiker’s work is significant because it highlights prominent societal challenges prevalent in post-apartheid society. By analysing Duiker’s novels one acquires a better understanding of this author, an understanding of the world that contributed to the creation of his texts and his contribution to South African literature. Insight into Duiker’s fictional world allows for a careful investigation of the prominent societal issues prevalent in Duiker’s work - a world riddled with violence, issues of sexuality and psychological distress. For this purpose this thesis is premised on the notion that underpinning K. Sello Duiker’s oeuvre is a central focus on dreams, sexuality and fantasy. Logically, therefore, the main focus of the study is specifically on the inner working of the characters’ minds and how they deal/ or are unable to cope with contemporary social concerns, often resulting in psychological turmoil and dysfunctionality. For this reason, prominent themes examined in this study are the interpretation of dreams, an exploration of sexuality and an examination of fantasy in the three novels. Psychoanalytic literary theory, with the main focus being specifically on the theories presented by Sigmund Freud is used as an analytic tool to read Duiker’s texts. Psychoanalytic theory is arguably the most appropriate for analysing Duiker’s novels as it allows one to investigate the characters’ psyches and the psychological effect of societal influences on these characters. In addition, one is also able to examine how the characters are able/ unable to deal with the trauma caused by the contemporary issues in society – issues of violence, sexuality and psychological distress. Thus, one is able to grasp an overall understanding of the characters’ behaviour and actions. Furthermore, the characters’ experiences are based on the behaviour and incidents of real people, people suffering from psychological dysfunctionality, sexuality issues and identity crisis. The first chapter discusses post-apartheid literature, and provides a brief background on Duiker, his works and his conception as a writer. Chapter two provides an overview of psychoanalytic theory and on the relevant theories of Sigmund Freud. Chapter three offers a reading of Thirteen Cents, a novel that pays particular attention to the lives of children living on the streets of Cape Town. In the next chapter The Quiet Violence of Dreams is examined with a special focus on Duiker’s experimentation with form in the construction of this novel. Aspects pertaining to sexuality and dreams are also examined. Chapter five pays particular attention to magical realism and fantasy in The Hidden Star.

- Description: South Africa has an estimated 920 000 patients on antiretrovirals (ARVs), the largest number of patients in any country. ARV therapy demands adherence levels in excess of 95% to avoid development of drug resistance, but adherence to ARV therapy is estimated to be only between 50% and 70%. Poor medication adherence is acknowledged as a major public health problem, reducing the effectiveness of therapy and promoting resistance to ARVs. More than two thirds of the South African population have marginal reading skills and this significantly influences a patient’s ability to read and understand health-related information. Patient education materials tailored for the South African population could be a useful aid in facilitating communication with patients and perhaps impact positively on their medicine-taking behaviour. This behaviour is influenced by patient knowledge, beliefs, attitudes and expectations and includes self-management, self-efficacy and adherence. Self-efficacy, which refers to patient confidence in the ability to self-manage medicine taking, is a key factor influencing adherence. This study aimed to develop illustrated patient information leaflets (PILs) and medicine labels for all first-line ARV regimens used in the public health sector in South Africa and, using a randomised control study design, to investigate the impact of these illustrated information materials on knowledge, medication-taking behaviours and health outcomes in HIV/AIDS patients taking ARVs. To achieve this aim, the objectives were to assess HIV/AIDS and ARV-related knowledge, as well as self-efficacy and adherence to ARV therapy; to assess the influence of demographic variables on knowledge, adherence and self-efficacy; to assess the influence of the information materials on knowledge, self-efficacy and adherence and to assess the association of knowledge with health outcomes. Medicine labels and PILs, both English and isiXhosa, were developed for ARV regimens 1a, 1b, 1c and 1d. The 8-item Morisky Medication Adherence Scale (MMAS-8) and HIV Treatment Adherence Self Efficacy Scale (HIV-ASES) instruments for measuring respectively adherence and self-efficacy, were modified to optimize clarity, simplicity and cultural acceptability and were translated into isiXhosa using a multi-stage translation-back translation. The questions and the rating scales, for both the MMAS and HIV-ASES, underwent preliminary qualitative evaluation in focus group discussions. Patients were recruited from local Grahamstown clinics. A pilot study to evaluate applicability of the instruments was conducted in 16 isiXhosa AIDS patients on ARVs and the results from this study informed further modifications to the instruments. One hundred and seventeen patients were recruited for the randomised control trial and were randomly allocated to either control group (who received standard care) or experimental group (who received standard care as well as pictogram medicine labels and the illustrated PIL). Interviews were conducted at baseline and at one, three and six months. Data were analysed statistically using the t-test, chi-squared test and ANOVA (Analysis of Variance) at a 5% level of significance. Correlations were determined using Pearson and Spearman rho correlations. Approval was obtained from Rhodes University Ethical Standards Committee, Settlers Hospital Ethics Committee and the Eastern Cape Department of Health. The results of this research showed that illustrated PILs and medicine labels enhanced understanding of HIV/AIDS and ARV information, resulting in a mean overall knowledge score in the experimental group of 96%, which was significantly higher than the 75% measured in the control group. Variable knowledge scores were measured in three areas: baseline knowledge of general HIV/AIDS-related information was good at 87%, whereas knowledge scores relating to ARV-related information (60%) and side-effects (52%) were lower. These scores improved significantly in the experimental group over the 4 interviews during the 6 month trial duration, whereas in the control group, they fluctuated only slightly around the original baseline score. There was no significant influence of gender on knowledge score, whereas health literacy, education level and age tested (at one and three months) had a significant influence on knowledge. Self-efficacy and adherence results were high, indicating that the patients have confidence in their ability to adhere to the ARV therapy and to practice optimal self-care. Age, gender and education, in most cases, significantly influenced self-efficacy, but were found to have no effect on adherence. The CD4 count improved over the trial duration which may have been influenced by a number of factors, including better knowledge of ARVs and improved adherence. No significant parametric correlation was found between knowledge score and change in CD4 count, however, Spearman's rho showed significance (rs=0.498; p=0.022). Both patients and healthcare providers were highly enthusiastic about the illustrated labels and PILs, and indicated their desire for such materials to be routinely available to public sector HIV/AIDS patients. The isiXhosa version of the PIL was preferred by all the patients. These simple, easy-to-read leaflets and illustrated medication labels were shown to increase understanding and knowledge of ARVs and HIV/AIDS in low-literate patients, and their availability in the first-language of the patients was central to making them a highly useful information source.

- Description: South Africa has an estimated 920 000 patients on antiretrovirals (ARVs), the largest number of patients in any country. ARV therapy demands adherence levels in excess of 95% to avoid development of drug resistance, but adherence to ARV therapy is estimated to be only between 50% and 70%. Poor medication adherence is acknowledged as a major public health problem, reducing the effectiveness of therapy and promoting resistance to ARVs. More than two thirds of the South African population have marginal reading skills and this significantly influences a patient’s ability to read and understand health-related information. Patient education materials tailored for the South African population could be a useful aid in facilitating communication with patients and perhaps impact positively on their medicine-taking behaviour. This behaviour is influenced by patient knowledge, beliefs, attitudes and expectations and includes self-management, self-efficacy and adherence. Self-efficacy, which refers to patient confidence in the ability to self-manage medicine taking, is a key factor influencing adherence. This study aimed to develop illustrated patient information leaflets (PILs) and medicine labels for all first-line ARV regimens used in the public health sector in South Africa and, using a randomised control study design, to investigate the impact of these illustrated information materials on knowledge, medication-taking behaviours and health outcomes in HIV/AIDS patients taking ARVs. To achieve this aim, the objectives were to assess HIV/AIDS and ARV-related knowledge, as well as self-efficacy and adherence to ARV therapy; to assess the influence of demographic variables on knowledge, adherence and self-efficacy; to assess the influence of the information materials on knowledge, self-efficacy and adherence and to assess the association of knowledge with health outcomes. Medicine labels and PILs, both English and isiXhosa, were developed for ARV regimens 1a, 1b, 1c and 1d. The 8-item Morisky Medication Adherence Scale (MMAS-8) and HIV Treatment Adherence Self Efficacy Scale (HIV-ASES) instruments for measuring respectively adherence and self-efficacy, were modified to optimize clarity, simplicity and cultural acceptability and were translated into isiXhosa using a multi-stage translation-back translation. The questions and the rating scales, for both the MMAS and HIV-ASES, underwent preliminary qualitative evaluation in focus group discussions. Patients were recruited from local Grahamstown clinics. A pilot study to evaluate applicability of the instruments was conducted in 16 isiXhosa AIDS patients on ARVs and the results from this study informed further modifications to the instruments. One hundred and seventeen patients were recruited for the randomised control trial and were randomly allocated to either control group (who received standard care) or experimental group (who received standard care as well as pictogram medicine labels and the illustrated PIL). Interviews were conducted at baseline and at one, three and six months. Data were analysed statistically using the t-test, chi-squared test and ANOVA (Analysis of Variance) at a 5% level of significance. Correlations were determined using Pearson and Spearman rho correlations. Approval was obtained from Rhodes University Ethical Standards Committee, Settlers Hospital Ethics Committee and the Eastern Cape Department of Health. The results of this research showed that illustrated PILs and medicine labels enhanced understanding of HIV/AIDS and ARV information, resulting in a mean overall knowledge score in the experimental group of 96%, which was significantly higher than the 75% measured in the control group. Variable knowledge scores were measured in three areas: baseline knowledge of general HIV/AIDS-related information was good at 87%, whereas knowledge scores relating to ARV-related information (60%) and side-effects (52%) were lower. These scores improved significantly in the experimental group over the 4 interviews during the 6 month trial duration, whereas in the control group, they fluctuated only slightly around the original baseline score. There was no significant influence of gender on knowledge score, whereas health literacy, education level and age tested (at one and three months) had a significant influence on knowledge. Self-efficacy and adherence results were high, indicating that the patients have confidence in their ability to adhere to the ARV therapy and to practice optimal self-care. Age, gender and education, in most cases, significantly influenced self-efficacy, but were found to have no effect on adherence. The CD4 count improved over the trial duration which may have been influenced by a number of factors, including better knowledge of ARVs and improved adherence. No significant parametric correlation was found between knowledge score and change in CD4 count, however, Spearman's rho showed significance (rs=0.498; p=0.022). Both patients and healthcare providers were highly enthusiastic about the illustrated labels and PILs, and indicated their desire for such materials to be routinely available to public sector HIV/AIDS patients.

- Description: The combination of chemotherapy and photodynamic therapy was investigated by the synthesis and characterisation of phthalocyanine conjugates with Pt complexes. The complexes synthesized are: hydroxoaluminum trikis(diaquaplatinum) octacarboxyphthalocyanine (OHAlOCPc(Pt)3) and hydroxoaluminum tetrakis(diaquaplatinum) octacarboxyphthalocyanine (OHAlOCPc(Pt)4). The platinated phthalocyanine complexes gave long triplet lifetimes of 577 and 526 μs for OHAlOCPc(Pt)3 and OHAlOCPc(Pt)4, respectively. The triplet quantum yields were found to be 0.45 for OHAlOCPc(Pt)3 and 0.57 OHAlOCPc(Pt)4 while the singlet oxygen quantum yields were found to be 0.38 and 0.48, respectively.

- Description: Agriculture plays an important role in the economy of every nation. Most countries depend on agriculture and other industries to survive. Economies around the world experience difficulties. There are many countries that have the potential to stimulate their economic growth through agriculture. The untapped resources have the potential of providing food, jobs and increased financial stability. Many countries utilise their agricultural sector to grow their economy. The growth of unemployment in South Africa has a big impact on our economy. This has caused an increase in poverty and unemployment (Ukpere & Slabbert, 2009). Women’s role in agriculture and food security is critical, but there is still lack of visibility regarding their participation and contribution in agriculture and development in general. This has led to two forms of agriculture in South Africa; so-called subsistence farming in the communal areas and white commercial farming (Kwa, 2001). Most emerging farmers are on communal land where they share decisions and ownership is unsecured, which discourages investment and limits productivity (Farmer's weekly, 2012). The main objective of the research was to determine if the women in the Tsitsikamma (Eastern Cape, South Africa), area have knowledge and strategies to manage their agribusiness in order to create an enabling environment and be competitive in their farming businesses. The qualitative method was used to answer questions in order to understand people’s perceptions, perspectives and understanding of particular situations. It is based on the belief that the researcher’s ability to interpret and make sense of what he or she sees is critical for an understanding of any social phenomenon. In seeking to create an enabling environment, a qualitative analysis investigated this particular situation. The sample consisted of 25 out of a possible 30 women in the agriculture industry. A structured questionnaire was used and interviews were conducted with women involved in agriculture regardless of owning a farm. This study was based in the farming industry, particular farm women who are interested or involved in agribusiness in the Tsitsikamma region. The results of the questionnaire revealed key findings, which enabled the researcher to draw meaningful conclusions and recommendations. The findings have suggested that the women farmers can overcome the identified constraints affecting the opportunities to grow their farming businesses. Further empirical results indicated that they do not have any strategies in running their farming businesses. The study also highlights areas in agribusiness that should be improved.

- Description: Competition among firms is a central feature in all free market economies such as South Africa. One of the biggest threats to competition is the presence of cartels in markets. Cartels are firms which collude and compete unfairly in order to obtain monopoly-like profits. For more than fifty years South Africa’s economic landscape has been dominated by a vast network of cartels invital industries, such as bread, cement and fertiliser. South Africa promulgated the Competition Act 89 of 1998 to eradicate cartels and promote and maintain competition within the South African economy. The Competition Act 89 of 1998 prohibits cartel activity and provides for a fine of 10% of turn over for firms found to have engaged in cartel activity. For a variety of reasons, these administrative fines have failed to deter firms from commencing and/or continuing to engage in cartel activity. This is evidenced by the increasing number of firms engaged in large -scale cartels in essential industries, such as construction and food. Public outcry and global trends have persuaded legislators to enactment more stringent penalties in the Competition Amendment Act 1 of 2009. Section 12 of the Competition Amendment Act , which inserts section 73A, creates a cartel of fence in terms of which a director who causes his firm to engage in cartel activity faces ten year imprisonment or a fine of R500, 000. This research shall critically analyse the Competition Amendment Acts effect on deterring cartel activity in South Africa. Despite the legislators’ aim to provide a bigger deterrent for engaging in cartel activity, section 73A of the Competition Amendment Act arouses scrutiny. Firstly, the promulgation of the new cartel offence is contrary to the decimalisation trend in South African company law which recognises the difficulty in enforcing complex regulatory offences with criminal provisions. Secondly, Section 73(5)A appears to infringe an accused director's right to be presumed innocent. Lastly there are co-ordination issues between the National Prosecuting Authority and the Corporate Leniency Policy relating to the granting of prose cutorial immunity for firms which cooperate with the Competition Commission. There search will out line these problems in full. With regards to the problems caused by section 73A, the research will use a comparative analysis with the positionin the United States. Of all the jurisdictions which criminalise cartel activity, the United States was one of the earliest and the most prolific insecuring convictions for directors who cause their firms to engage in cartel activity. The United States has taken innovative steps to supplement their public cartel enforcement drive such as the prosecution of international cartels and the use of private actions. In this regard, the research will extrapolate favourable cartel enforcement measures from the United States for recommendation in order to assist with South Africa’s cartel enforcement and alleviate the problems caused by section 73A, outlined above.

- Description: Even though South Africa‟s historical inequalities are addressed, serious economic disparities are still evident. The informal economy is not flourishing as it should be, especially when compared to other fledgling democracies on the continent and this poses a policy question since most of the participants of this sector are from the previously disadvantaged section of the population. One policy dilemma that comes to the fore is about how to ensure that there is increased productivity in the sector so that the sector‟s contribution to the national economy can be enhanced. While the actual share of the economy contributed by the informal economy is difficult to ascertain there is evidence that this constitutes less than one fifth of South Africa‟s GDP. Within the informal economy trading appears to be the dominant economic activity. Despite the importance of the informal trade the sector has not attracted the needed attention in the literature either locally or internationally. The area that has received much attention by researchers has been the informal financial sector. Drawing on a standard revenue model for the informal trade sector this study examines the factors that explain differences in the performance of the retail trade businesses; given that these can be identified an effort should then be made to explore the policy measures that can improve the performance of these firms. The study is based on a sample of 300 informal retail traders in the Port Elizabeth environ. The regression analysis presented in this study suggests that residential area, capital, labour, inventory and age of a business are important determinants of an informal retail trade firm‟s revenue. Very few informal retailers indicated that they had businesses training. The survey results show that having a supplier close to the business assists in reducing transport costs, hence the increase in profit margins. Shelters and storages were found to be very useful in the operation of informal businesses.

- Description: In recent years, concern about food safety linked to health issues has seen a rise in private food safety standards in addition to the regulations set by the Food and Agriculture Organisation (FAO) in collaboration with the World Health Organisation (WHO). These have presented challenges to producers and exporters of agricultural food products especially the producers of fresh fruits and vegetables. In spite of the food safety-linked challenges from the demand side, the vast range of business-environment forces pose equally formidable challenges that negatively impact on the exporting industries’ ability to maintain or improve their market shares and their ability to compete in world markets. The objective of this study was therefore to establish the competitiveness of the South African citrus industry in the international markets within this prevailing scenario. Due to the diversity of the definitions of competitiveness as a concept, this study formulated the following working definition: “the ability to create, deliver and maintain value and constant market share through strategic management of the industrial environment or competitiveness drivers”. This was based on the understanding that the international market shares of an industry are a function of forces in the business environment which range from intra-industry, external and national as well as the international elements. The unit of analysis were the citrus producers engaged in export of their products and the study made use of 151 responses by producers. The study adopted a five-step approach to the analysis of the performance of the South African citrus industry in the global markets, starting with the analysis of the Constant Market Share (CMS) of the South African citrus industry in various world markets, establishing the impact of the business environmental factors upon competitiveness, establishing the costs of compliance with private food safety standards, determining the non-price benefits of compliance with the standards, as well as highlighting the strategies for enhancing long-term competitiveness of the industry in the international markets. South Africa is one of the top three countries dominating the citrus fruit export market. Since its entry into the citrus fruit exports market in the 1900s, the industry has sustained its activity in the international market. The Constant Market Share Analysis shows that, amidst the challenges on the international market side, and the changes in the business environment, over much of which the industry has limited control and influence, the industry has maintained its competitive advantage in several markets. The CMS shows that South Africa’s lemons are competitive in America. Despite a negative trend, the South African grapefruit has been competitive in France, Greece, Italy, the Netherlands and Spain. Oranges have been competitive in the Greece, Italy, Portugal, UK, Asian and Northern Europe markets. Competitiveness in these markets has been due to the inherent competitiveness of the industry. Competitiveness in such markets as the Middle East has been attributed to the relatively rapid growth of these markets. The South African citrus industry has similarly undergone many major processes of transformation. The business environmental factors influencing its performance have ranged reform to the challenges beyond the country’s borders. These factors directly and indirectly affect the performance of the industry in the export market. They have influenced the flow of fruits into different international destinations. Of major concern are the food safety and private standards. Challenges in traditional markets as well as opportunities presented by demand from newly emerging citrus consuming nations have seen a diversification in the marketing of the South African citrus. The intensity of competition in the global market is reflected by the fluctuations in the market shares in different markets as well as the increase and fluctuations of fruit rejection rates in some lucrative markets such as America. A combination of challenging national environmental forces and stringent demand conditions negatively impact on revenues especially from markets characterised by price competitiveness. This study identified cost of production, foreign market support systems, adaptability, worker skills, challenges of management in an international environment and government policies such as labour and trade policies as some of the most influential obstacles to competitiveness. Some of the most competiveness-enhancing factors were market availability, market size, market information, market growth and the availability of research institutions. However, compliance with private standards still poses a challenge to the exporters. The different performance levels of the industry in various markets prove the dissimilarity of the demand conditions in the global market. These are supported by the negative influence associated with the foreign market support regimes as well as the challenges associated with compliance with private food safety standards. While market availability, market growth, market information and size were identified as enhancing competitiveness, the fluctuations and inconsistencies in the competitiveness of the industry in different foreign markets require more than finding markets. Resource allocation by both the government and the industry may need to take into account the off-setting of the national challenges and support of farmers faced with distorted and unfair international playing fields. Otherwise, market availability is not a challenge for the industry save meeting the specifications therewith as well as price competitiveness which is unattainable for the South African citrus producers faced with high production costs. For the purposes of further study, it is recommended that account should be taken of all the products marketed by the industry (including processed products such as fruit juices) in order to have a whole picture of the competitiveness of the industry in the international market. This study also proffers a new theoretical framework for the analysis of the business environment for the citrus industry and other agro-businesses. This framework takes into account the indispensability of the food safety standards and measures as well as the diversity of the global consumer and the non-negotiability of food trade for the sustenance of the growing population.

Challenges in traditional markets as well as opportunities presented by demand from newly emerging citrus consuming nations have seen a diversification in the marketing of the South African citrus. The intensity of competition in the global market is reflected by the fluctuations in the market shares in different markets as well as the increase and fluctuations of fruit rejection rates in some lucrative markets such as America. A combination of challenging national environmental forces and stringent demand conditions negatively impact on revenues especially from markets characterised by price competitiveness. This study identified cost of production, foreign market support systems, adaptability, worker skills, challenges of management in an international environment and government policies such as labour and trade policies as some of the most influential obstacles to competitiveness. Some of the most competiveness-enhancing factors were market availability, market size, market information, market growth and the availability of research institutions. However, compliance with private standards still poses a challenge to the exporters. The different performance levels of the industry in various markets prove the dissimilarity of the demand conditions in the global market. These are supported by the negative influence associated with the foreign market support regimes as well as the challenges associated with compliance with private food safety standards. While market availability, market growth, market information and size were identified as enhancing competitiveness, the fluctuations and inconsistencies in the competitiveness of the industry in different foreign markets require more than finding markets. Resource allocation by both the government and the industry may need to take into account the off-setting of the national challenges and support of farmers faced with distorted and unfair international playing fields. Otherwise, market availability is not a challenge for the industry save meeting the specifications therewith as well as price competitiveness which is unattainable for the South African citrus producers faced with high production costs. For the purposes of further study, it is recommended that account should be taken of all the products marketed by the industry (including processed products such as fruit juices) in order to have a whole picture of the competitiveness of the industry in the international market. This study also proffers a new theoretical framework for the analysis of the business environment for the citrus industry and other agro-businesses. This framework takes into account the indispensability of the food safety standards and measures as well as the diversity of the global consumer and the non-negotiability of food trade for the sustenance of the growing population.

- Description: Malawi is divided into three regions, namely: Southern, Central and Northern regions. Each Region has an independent Water Board owned by Government to supply it with portable water. The Constitution of the Republic of Malawi 1994, Chapter 3, Section 13 recognizes public trust and good governance as some of the fundamental principles of National Policy and thereby promised to introduce measures which will guarantee accountability, transparency, personal integrity and financial probity and which by virtue of their effectiveness will strengthen confidence in public institutions. In order to improve service delivery and fulfill the stated constitutional imperatives, the Malawi Government issued the following statement in 2008, one of our cardinal agenda is reform aimed at changing the way things are done in the public service so that it becomes more efficient and responsive to the needs of all Malawians. As a Government we realize that no matter how brilliant plans and development agenda can be, they will be frustrated unless major reforms are initiated and implemented to facilitate required changes to support the development process. Major changes are necessary in values, beliefs, norms, attitudes and mindsets to help create an enabling environment for the effective management of reforms across the public service. We need to move away from the business as usual type of attitude and fully account for time that we are paid for from public funds if we are to join the prosperous nations (National Framework for Public Sector Management Reform, June, 2008).

- Description: Water is an indispensible and yet a difficult resource to be renewed, thus water scarcity has become one of the major challenges faced worldwide, with the Southern regions of Africa being the most impacted and affected, especially the Eastern Cape Province of South Africa where rural communities depend on receiving waterbodies that are often negatively impacted by wastewater final effluents. This present study was conducted between August and December 2010 to assess the physicochemical and microbial qualities of the final effluents of peri-urban and rural communities based wastewater treatment plants in the Eastern Cape Province. The physicochemical parameters were determined on site and in the laboratory, while bacteriological qualities were determined using culture based techniques. The virological qualities were determined by molecular methods using reverse transcriptase polymerase chain reaction for the target RNA virus and the conventional polymerase chain reaction for the target DNA virus. For both wastewater treatment plants, the physicochemical parameters ranged as follows: chemical oxygen demand (5.95-45 mg/L); total dissolved solids (114.5-187.0 mg/L); salinity (0.12-0.20 psu); temperature (14.2-25.7oC); pH (6.0-7.6); nitrate and nitrites (1.55-6.7 mg/L and 0.023-1.15 mg/L respectively); biological oxygen demand (3.5-7.8 mg/L); turbidity (1.49-6.98 NTU); and chlorine residual (0-2.97 mg/L). Feacal indicator bacteria counts ranged as follows: feacal coliforms (0-1.25×104 cfu/100 ml); total coliforms (0-3.95×104 cfu/100 ml); and enterococci (0-5.0×103 cfu/100 ml). xviii Seventy five percent of the rural community based plant and 80 percent of the peri-urban community based plant were positive for coxsackie A virus, while hepatitis A virus was detected in all the rural community based plant 80 percent of the peri-urban community based plant. This study suggests the need for intervention by appropriate regulatory agencies to ensure regular monitoring of the qualities of final effluents of wastewater treatment facilities in the Eastern Cape Province and ensure compliance to established guidelines.

- Description: After the 1994 elections education reform has been characterized by the introduction of laws and policies, including IQMS, that seek to reconcile post‐apartheid traditions to practices that would address deficiencies borne by the era in the education field. The IQMS is a clear reaction to the autocratic mode of evaluation that operated during the apartheid era and is a major shift from the old paradigm of external evaluators. It was designed to review performance and identify strengths and weaknesses, encouraging personal and professional development, drawing on peer and collegial feedback rather than official Department of Education surveillance. However, recent studies have shown that the IQMS has failed and is failing to achieve what it was intended to achieve. This study examines the reasons for this failure in a secondary school in the Eastern Cape, South Africa. This research is an interpretive case study that uses observation, document analysis and interviews utilising theories of learning organizations, management and leadership. The study reveals that the policy is not applied in the way it was intended and is failing in this regard. The policy process has been bureaucratised and suffers from superficial compliance. The developmental thrust of the policy seems to have been lost. It was also discovered that the involvement of teacher unions has both positively and negatively affected the implementation process and that the support schools receive from the department is not enough to keep the policy alive in schools. This research is likely to benefit school principals, policy makers and implementers, and IQMS coordinators, as it provides clarity on the issues restraining IQMS implementation in schools. The study also demonstrates the need for school principals to consider adopting transformational leadership as a strategy to lead teachers against political influence and expose them to professional development opportunities.

- Description: This review article synthesizes the authors' several decades of multidisciplinary natural and social science and applied marine resource management experience in the Asia-Pacific region to examine the strengthening of coastal and marine resource management and conservation using alliances between local communities and external institutions. The objective is to assist the design of resource management and conservation programs that enhance the capacity of coastal communities in Oceania to confront both diminishing marine resources and the effects of climate change by providing guidelines for protecting marine biodiversity and vulnerable ecosystem functions. This article describes a management framework that hybridizes local beliefs and institutions expressed in customary management (CM) with such modern management concepts as marine protected areas (MPAs) and ecosystem-based management (EBM). Hybrid management accommodates the social, political, economic, and cultural contexts of Oceanic communities and, compared with recent or conventional management approaches, can therefore better address fundamental local concerns such as coastal degradation, climate change, sea level rise, weak governance, corruption, limited resources and staff to manage and monitor marine resources, and increasing poverty. Research on the hybridization of management systems demonstrates opportunities to establish context-appropriate EBM and/or other managerial arrangements that include terrestrial and adjacent coastal-marine ecosystems. Formal and informal CM systems are widespread in Oceania and in some parts of Southeast Asia, and if appropriate strategies are employed rapid progress toward hybrid CM-EBM could be enabled.

- Description: Reactive power compensation, as generated by capacitors, has been used to mitigate the constraints of power transmission and improve the power transfer of the transmission system of the South African power utility, Eskom‟s 66/22kV Albany-Wesley transmission system. An investigation was carried out on a number of current compensation schemes, and their operations, by means of load flow analysis. Different capacitor qualities and technologies were applied to alter the transmission line characteristics that resulted in acceptable voltage regulation. This resulted in easing the load on the lines and transformers and hence reducing line losses. For long transmission lines, utilities need voltage support, as provided for by different voltage compensators, to keep the terminal voltage within standard voltage regulation, and meet the designed power demand. The approach to large and small scale compensation was tested and the outcomes revealed distinct patterns that were used to confirm the hypothesis and improve the transfer of power. The templating temperature and thermal perspective as used by Eskom on line design was discussed and used to design a new transmission line. Load flow solutions were also used to plan and design the optimised transmission system as well as to determine the specification and location of the compensating capacitor banks. Capacitor banks, as a source of reactive power, were used to model the compensation in this research. Electrical protection and faults associated with the capacitors banks were discussed, as prevention to total blackout or load shedding on the transmission line in case of established contingency. Long term investment plans, to meet future electricity demands, require substantial investment hence a financial survey was carried out. Finally this dissertation selects a viable solution to meet the electrical power demands and then recommends a way forward for the Eskom‟s 66/22kV Albany-Wesley line.
