- Description: Zea mays stem and its activated carbon were prepared through chemical activation method using four different activating reagents (NaOH, H₃PO₄, H₂SO₄, KOH) and were used as adsorbents for the removal of Pb(II), Cu(II), Hg(II) and Cr(III) from aqueous solution. The results shows that activated carbon has high surface area and pore volume compared to the powdered raw Zea mays stem. Prepared activated carbon was characterized using physico-chemical properties such as carbon yield, iodine number, moisture content, percentage adsorption, and analytical instruments such as Fourier transform Infrared spectroscopy (FTIR), atomic absorption spectrometer (AAS), scanning electron microscopy (SEM), Energy Dispersive X-ray analysis (EDS), powder X-ray Diffraction (pXRD). The adsorption of Pb(II), Cu(II), and Cr(III) ions were pH, contact time, and concentration dependent. Based on the results obtained from the batch experiments, activated carbon prepared from Zea mays stem is not good enough for the removal of Hg(II) from aqueous solution. Adsorption ability was calculated and found to be 66.67% for activated carbon obtained from H₂SO₄, 21.21% for activated carbon obtained from KOH, and 20% for activated carbons obtained from NaOH and H₃PO₄. The pH 5-6 was chosen for all experiments, contact time was 2 hours, and adsorbent dosage was 2 g, initial concentration range from 200, 400, 600, 800, and 1000 ppm at room temperature. The metal ion removal trend was found in the order Pb(II)>Cu(II)>Cr(III)>>Hg(II). The Langmuir model fitted well in most of the cases with > 0.99. Consequently, the adsorption of Pb(II) and Cu(II) followed Langmuir isotherm model while that of Cr(III) best fitted the Freundlich isotherm model. The results indicated that the adsorption process followed two possible mechanisms. (I) Metal ion – adsorbent complex model and (II) Metal ion – ion-exchange adsorbent complex model.

- Description: The South African Schools Act (No. 84 of 1996) mandates the government to make financial allocations to needy schools. Section 21 of the Act read together with the National Norms and Standards for School Funding, stipulates that schools falling into certain categories (quintiles) receive given amount of funds per each and every learner. The funds are meant to help promote the equal and unparalleled access to education for all citizens as set-out in Section 29 of the Constitution of the Republic of South Africa (1996). The study focused on investigating the manner in which two selected Section 21 primary schools are managing their allocated funds. The empirical study made use of a qualitative paradigm through which data was collected using interviews and focus group discussions to collect data from a sample comprising of thirty-five respondents. In terms of data analysis, the study used a qualitative analysis approach to interpret data into readable information for the various categories of audiences in the study. The findings of the study were, inter alia, that financial management skills are low in the schools, the amounts appropriated to schools needs to be revised upwards because schools need more funding for renovations and property development in schools, sanctions for those guilty of school financial misconduct are too soft and auditing of financial record is not being constantly done. The study recommends that the following be considered in order to help improve school financial management; the training of financial officers in school on how to best manage funds, imposition of stiffer penalties for offenders of financial misconduct and increase in allocation aimed at school property development.

- Description: The local level of government plays a pivotal role in the delivering of service in Bor county of Jonglei State in South Sudan. As the world‟s newest nation attained independence in July 2011, the republic of South Sudan face a huge mountain to climb in terms of service delivery for socio – economic transformation. A country which has ransacked by civil wars and economic exclusion of its people in the past, South Sudan needs to pool resources together for the sustainable betterment of its citizens. Service is solely dependent on leadership and effective and efficient service rendering, requires a people – centred, accountable and professional leadership. Traditional leaders have played a key role in the welfare of their subjects in South Sudan beginning long back, they have led, counselled, mediated disputes, allocated and managed land as well as preservation of customs and cultures. The study sought to assess shifting roles of traditional leaders in local government services delivery. It comprises of six chapters which are chronologically arranged. The main objectives of the study were to establish role which were played by Bor traditional leadership to promote service delivery at the local government level before independence, after independence, the extent to which the roles shifted, challenges they face currently and ways of solving them. The research question which guided the sought to find the answers to what roles traditional leaders played before and after independence, the shifting of roles, challenges and ways of addressing them. The paradigm used in the study is the qualitative research approach where empirical data was collected from a representative sample of 9 respondents. Data was collected using the non-random sampling techniques of purposely sampling. The researcher observed strict ethical guideline which includes informed consent, privacy and confidentiality. The study found out that traditional leaders played various roles under various governments. There were shifts in traditional leadership roles leaders can play and did not completely divert the roles leaders can play in service delivery. The study further established that Bor traditional leaders were willing service at the local government level but that they faced challenges particularly that of insecurity and war – related problems. The study therefore, recommended that government should pay attention to security in Bor County and the county at large. It was also recommended that government should train traditional leadership roles such as those applied in Ghana, Uganda, South Africa and Zimbabwe. Despite the said shift in roles, traditional leaders remain a key asset to the development of South Sudan.

- Description: Employee commitment is one of the most important aspects that help an organisation achieve its desired goals. This study investigates the possible effects of gender and age differences between managers and employees on organisational commitment among lower-level employees in selected factories in the Buffalo City Metropolitan area. The organisational commitment instrument used in this research is the Meyer and Allen (1997) organisational commitment questionnaire which contains 18 items (6 items for each scale: affective commitment, continuance commitment and normative commitment). For this purpose, a sample of 100 lower-level employees was used. The results indicated significant differences in the unexpected directions in affective commitment and continuance commitment between male employees supervised by male managers and male employees supervised by female managers; male employees were found to have higher levels of affective and continuance commitment when supervised by female managers. Female employees were found to have a higher level of normative commitment when supervised by male managers than when supervised by female managers which was also in the unexpected direction. In addition, the study showed surprising results in terms of the social or cultural hypothesis where employees supervised by male managers and older managers were not significantly different in organisational commitment to those managed by female and by younger or same-age managers.

- Description: Performance management systems help align individual goals and objectives with those of the organisation. The system engages employees and thereby directs them toward achieving the strategic goals of the organisation. The purpose of this research study was to conduct a critical evaluation on the management and implementation of Performance management and development System in the Department of Local Government and Traditional Affairs. Despite the importance of performance management, most organisations find it difficult to implement, manage and sustain performance management systems and processes effectively. It is therefore crucial to ensure adequate planning, evaluation and training is done that will support a sustainable process. Given the strategic role played by the SMS, especially the management of Performance Agreements in the realization of government programmes, it is important that departmental officials make efforts to ensure compliance with its provisions. This study has shown that officials have not been accurate enough in their implementation of the PMDS. The study reveals that there is no staff development programme in place that would help develop staff members to grow in the different fields of their jobs. This is a sound reason why staff responded that they are not happy with the current system. It would appear that management does not devote a great deal of time to staff development. The focus of the PMDS needs to be changed from an output-focused system to a management development system, where there is an increased focus on the development of competencies, compared to the current focus on rewarding only output.

- Description: The study investigates the relationship between stock market performance and business cycles in South Africa for the period 2002-2009 using monthly data. This is done by constructing a Vector Error Correction Model (VECM). The study specifies a business cycle model with the business cycle coincident indicator (BC) regressed against, the All Share Price Index (ALSI), Real Effective Exchange Rate (REER), Money Supply (M1), Inflation (CPIX) and the Prime Overdraft Rate (POR). The ALSI represents stock market performance whilst the rest of the variables are to enhance model specification. The study found a positive relationship between stock market performance and business cycles in South Africa. The results also indicated that business cycles are positively related to the lagged variable of the coincident indicator and money supply. In addition, the findings also reveal that BC is negatively related to interest rates and the real effective exchange rate.

- Description: Inflation and unemployment are perhaps the two most important challenges that face the South African economy of today. Firstly, the study examines the relationship between monetary policy and the two economic fundamentals (inflation and unemployment), using the VEC modeling technique. The model regresses the monetary policy variable against inflation and unemployment growth over the period 1980-2008. The results suggest that (1) there is a long run relationship between inflation and unemployment (2) monetary policy reacts more to variations in inflation compared to variations in unemployment. Secondly, the relationship between inflation and unemployment as explained by the Phillips curve is investigated. The results show that there is a positive relationship between inflation and unemployment.
