- Description: Africa’s public service faces many challenges for improved service delivery and this necessitates an administration that is committed, strong, people focused, and has the necessary skills and expertise to respond to the challenges and opportunities. Leadership in the work place is becoming a growing challenge for institutions especially in the public service. Good leadership throughout the public and private sector is critical for building effective countries, ensuring stability and promoting economic growth. Leadership is therefore responsible for encouraging certain fundamental values that will encourage trust and reinstate credibility with the public. The aim of the study was to investigate leadership styles that drive service delivery at a selected municipality. This was done by looking at the influence the following have on service delivery: selflessness, individualism, communalism, collectivism, cooperativeness, materialism. During literature review leadership theories were discussed to introduce the concept to the reader as well different styles of leadership together with Ubuntu as an African perspective to leadership. The sample consisted of 103 employees at different organisational levels of a selected municipality in the Eastern Cape. The empirical results showed that only materialism was significantly and positively (r = 0.34, p < 0.01) related to service delivery (SD). It means by satisfying the respondents’ materialistic needs, public sector managers would increase service delivery in the selected municipality. Descriptive statistics were also calculated with regard to the prevailing levels of the targeted leadership styles in the municipality. The managerial implications of the empirical results were discussed in the study.

- 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: Acquired Immunodeficiency Syndrome (AIDS) is a human disease caused by the human immunodeficiency virus type 1 (HIV-1) and it is one of the biggest social, economic and health challenges in the world. The Joint United Nations Programme on HIV/AIDS (UNAIDS) and World Health Organization (WHO) estimated that between 33.4 to 46.0 million people around the world were living with HIV/AIDS in December 2005 and the highest estimates are in the Sub-Saharan Africa (around 25 million). In more developed countries a combined antiretroviral therapy called highly active antiretroviral therapy (HAART) is used, which results in reduced progression to AIDS in most patients. Despite the beneficial effects of HAART, significant side effects are experienced by treated patients. In addition, most infected people live in countries where the treatment is very expensive or, in many cases, not available at all. These people therefore rely on medicinal plants for health care. In this study, aqueous extracts from Sutherlandia frutescens and Lobostemon trigonus were screened for potential anti-HIV activities in a series of in vitro enzymatic assays, including reverse transcriptase, HIV-1 protease and glycohydrolases. Two extracts of Sutherlandia leaves (SFL-1 and SFL-2) were prepared that inhibited HIV reverse transcriptase and a Lobostemon leaf extract (LTL) was shown to also inhibit this enzyme. All extracts were assayed at 1.25mg/ml. Tannin content was determined for all active extracts using a tannic acid assay. SFL-1 and SFL-2 were found to contain about 6 percent and 7 percent tannins, respectively, and LTL contained 31% tannins by weight. Tannins were removed using polyamide columns and three fractions were collected for each. The extracts were also fractionated with Sephadex G-25, Amberlite IR 120 and Dowex 1-X8 as size exclusion, cation exchange and anion exchange, respectively. Extracts were also fractionated by preparative thin layer chromatography where two compounds were separated from S. frutescens extract with high activity against reverse transcriptase while showing insignificant inhibition towards other enzymes tested. SFL-BFW-10 and SFL-WEF-7 inhibited reverse transcriptase by almost 100 percent and the IC50 values calculated for these compounds were 0.34 and 0.23mg/ml, respectively. Cytotoxicity of these compounds was evaluated on Chang liver cells and peripheral blood mononuclear cells (PBMCs). None of these compounds showed any significant inhibition of cell proliferation. The purity of these compounds could not be confirmed because there was insufficient material to use in the techniques required to show purity and identification. Therefore, TLC was used to determine the nature of these compounds. SFL-BFW-10 was identified as an organic acid and SFL-WEF-7 was identified as flavonoid.
