- Description: Enterprises of all kinds, regardless of the sector, are directly or indirectly dependent on Information Technology (IT) to carry out their daily activities. With this in mind, and correlated with the problem statement that it is “the lack of IT governance principles that lead to exposing enterprises to IT-related threats, vulnerabilities, and risks”, the objective of this study was to establish an Information Technology Risk Management Framework for enterprises within the Food manufacturing industry in South Africa that will ensure that IT-related threats, vulnerabilities, and risks are properly managed. In order to accomplish this, the research followed a process called design science research. The design science research paradigm was used to create a design artificial artefact in the form of a framework. The Nelson Mandela University – Design Science Framework Methodology (NMU-DSFM) was adopted since the objective of the study was to develop a framework. The study has revealed that enterprises within the sector are indeed lagging behind in terms of IT governance principles, hence an artefact called the IT Risk Management Framework for Enterprises within Food Manufacturing Industries in South Africa was developed.

- Description: The study focused on the causes of service delivery protests in Alfred Nzo District Municipality. The aim of the study was to identify the challenges and the concerns of protestors and to highlight the underlying reasons behind the protests. This study started by reviewing the constitutional basis for basic service delivery, the legislative framework, background to Alfred Nzo District Municipality, the structural set- up of municipalities and related studies on service delivery protests. Thereafter, the candidate undertook original research on a valid focus group interview consisting of ward committees sampled from the areas considered as “hotspots” in the district of Alfred Nzo District Municipality. The researcher adopted a qualitative methodology for the analysis upon which conclusions were drawn. The study describes the respondents concerns, challenges and reasons for service delivery causes. This study provides evidence that the current challenges confronting the people of Alfred Nzo District Municipality and many citizens of South Africa are the result not only of historical factors, but also “crisis of service delivery”, which in turn is as a result of poor management, corruption, political interference in administration, cadre-deployment, demarcation issues, non- accountability of political and administrative leadership and insufficient funding by the donors and treasury. Furthermore, the results show that the majority of the respondents believe the protests are a result of anger and frustration. In conclusion the study proposes that the South African government must go back to the “Batho Pele” principles as they are regarded as the solution to address the impatience and violent protests.

- Description: The study focussed on the effectiveness of control measures for dealing with absenteeism of educators with specific reference to selected schools at Libode District in the Province of the Eastern Cape. It identified the policy framework including rules and regulations relating to the absenteeism of educators. It assessed the effectiveness of control measures which are currently at the disposal of the selected schools and it also investigated the challenges faced by school principals in addressing the challenge of absenteeism of educators in the selected schools. A qualitative research methodology was used in undertaking the study. Purposive sampling was used to select the schools and participants for the study. Participants were comprised of school principals and Education Development Officers. Data was collected through structured and semi-structured interviews. Literature study showed that the management of educator absenteeism is an important aspect of Human Resource Management in schools. Furthermore, the study found that control measures for dealing with absenteeism are not properly applied in many schools and there is no consistency in the manner in which they are utilised by school principals. The study also found that school principals are struggling to manage absenteeism to the extent that some of them are not sure how to deal with educators who abuse leave. The study recommends that school principals should be empowered on leave management through various forms of training which include workshops.

- Description: Since the adoption of the Constitution of the Republic of South Africa, 1996, which identified the three spheres of government as distinctive, interrelated and interdependent, the local government sphere has been perceived in many parts of the country to be failing to fulfil its mandate of delivering essential basic services to local communities. The mandate of the South African local sphere of government has been to provide a developmental and accountable local government and to ensure provision of services to communities in a sustainable manner. As a key developmental agent, local government is obliged by the Constitution of the Republic of South Africa 1996 to develop a culture of municipal governance that encourage and create conditions for the local community to participate in the affairs of the municipality. In this regard, ward committees have been introduced to municipalities as community structures to play a critical role in linking and informing the municipalities about the needs, aspirations and challenges of their communities. In adherence to national legislation, such as the Local Government: Municipal Structures Act 117 (Act117 of 1998) and the Local Government: Municipal Systems Act 2000 (Act 32 of 2000), the City of Cape Town Metropolitan Municipality established advisory structures in the form of ward committees throughout its area of jurisdiction to advise the municipal council on any matter within the council’s competence. As a representative structure of the community the ward committee is expected to serve as a link between the council and the community and for this purpose articulates community needs and aspirations to better the living standards of the community. Despite the stated objectives of ward committees, the Du Noon area has been identified by City of Cape Town Metropolitan Municipality IDP: 2012-2017 as the ward with backlogs in infrastructure and service delivery. This study evaluates the extent at which the Du Noon ward committee (Ward 104) is enhancing service delivery in its area of jurisdiction. A sequential use of mixed methods was preferred, since quantitative and qualitative research methods were found to be complementary rather than opposed approaches. Using both obtrusive and unobtrusive collection procedures, the methods employed proofed practically useful. To this end, the study sought to examine extent at which the Du Noon ward committee is enhancing service delivery in its area of jurisdiction. The study further attempted to suggest practical techniques of bringing a resolve to the challenges faced by the ward committee in as far as providing effective and efficient service delivery to the community without fail.

Liver steatosis and insulin-resistance : reversal by Sutherlandia frutescens

- Description: Type 2 diabetes mellitus (T2DM) is rapidly emerging as one of the greatest global health issues of the 21st century. Insulin-resistance is a condition associated with T2DM and in the cell it is defined as the inadequate strength of insulin signalling from the insulin receptor downstream to the final substrates of insulin action involved in multiple metabolic, gene expression, and mitogenic aspects of cellular function. To investigate the potential mechanisms involved in the development of insulin-resistance, two in vitro liver cell models were established using palmitate or a combination of insulin and fructose as inducers. The development of insulin-resistance was determined via the capacity of the hepatocytes to maintain normal glucose metabolism functionality by measuring hepatic gluconeogenesis and glycogenolysis. It was established that the treatments induced the development of insulinresistance after 24 hours chronic exposure. Previous studies have investigated the potential of Sutherlandia frutescens extracts as therapeutic agents for insulin-resistance. The aim of this study was thus to investigate the ability of a hot aqueous extract of S. frutescens to reverse the insulin-resistant state, via measuring gluconeogenesis and glycogenolysis, the associated changes in cellular physiology (lipid accumulation, oxidative stress, and acetyl- CoA levels), and changes in mRNA expression. The results showed that S. frutescens had a significant effect on reversing the insulin-resistant state in both models of insulin-resistance. Furthermore, S. frutescens was capable of reducing lipid accumulation in the form of triacylglycerol in the high insulin/fructose model, while this was unaffected in the palmitate model. However, S. frutescens did reduce the accumulation of diacylglycerol in the palmitate model. Oxidative stress, seen to be associated with the insulin-resistant state, was successfully treated using the extract, as indicated by a reduction in reactive oxygen species. However no change was seen in the nitric oxide levels, in either model. Interestingly, although S. frutescens had no effect on the level of acetyl-CoA in the insulin/fructose model, it was found to increase this in the palmitate model. It is suggested that this may be due to increased β-oxidation and metabolic activity induced by the extract. The analysis of mRNA expression gave some insight into possible mechanisms by which insulin-resistance develops, although the results were inconclusive due to high variability in samples and the possibility of the RNA being compromised. Future studies will address this issue. The results of this study reflect different proposed clinical causes of insulin-resistance through the responses seen in the two cell models. These indicate that liver steatosis and insulin-resistance are induced by high palmitate as well as high insulin and fructose levels, and reversed by S. frutescens. Therefore the potential of S. frutescens to be used as a therapeutic agent in the treatment of insulin-resistance is indicated by this study.

Study of milk marketing by selected dairy companies in Port Elizabeth

- Description: This paper concerns itself with decreasing milk consumption in the Port Elizabeth area and how the marketing mix influences marketing decisions. Personal interviews were conducted in different supermarkets to investigate consumer perceptions of milk, the brand purchased and how consumers use milk. The study indicated that people purchasing milk were very price conscious. Respondents showed almost no brand loyalty. However, respondents indicated that they were aware of the health benefits of drinking milk, although most used milk predominantly to whiten their tea and/or coffee. A comparison of the findings of this study to those of Geils (1981) and Hanekom (1990) indicates that the milk industry has the same problems in 1999 as it did in 1990 and in 1981. Findings reflect the unhealthy perception people have about milk. Many regard it as a child’s drink and others perceive it as fattening. Decreasing consumption figures indicate that there has been little effort or success from the dairy industry to change consumer perceptions of milk. Figures indicate that consumption of milk may be close to zero in 2015, if marketers of dairy companies do not improve the image of milk. However, a considerable amount of investment by overseas companies in Port Elizabeth dairies may increase marketing activities in the future. This paper begins with an overview of the major competitors in the Port Elizabeth area, highlighting their strengths and weaknesses. The importance of selecting the appropriate market mix for milk is discussed by explaining each mix element, namely, product, distribution, promotion and price. Distribution involves the delivery of the perishable product to outlets in the shortest space of time after production. Careful and efficient planning of refrigerated warehousing, transport and delivery services all indirectly contribute to the freshness and quality of milk. Promotion is one of the most important elements that can be used to change consumer perceptions of milk. It is necessary to select the correct message for the specific target group when advertising. Product benefits like milk’s purity, or naturalness, should be focused on rather than its creaminess and richness. Price constitutes the fourth element of the marketing mix. Price in the narrowest sense, is the amount of money charged for milk. The milk industry is intensely price sensitive which often results in price wars among competitors. Most consumers purchase the cheapest brand of milk indicating little brand loyalty, especially among top-end consumers.
