- Description: The success or failure of a local municipality is measured by the efficient provision of basic services to communities within the area of jurisdiction. Waste management is one of the basic services that pose serious environmental challenges. Various strategies have been developed as a means of waste management and recycling is a popular strategy as it has the potential to foster relations between the municipality and the community. Studies by the Department of environmental Affairs have confirmed that the delivery of waste management services by municipalities has capacity constraints including, but not limited to, landfill site operations, waste collection, processing and disposal, and waste management hierarchy (Department of Environmental Affairs, 2008). This research is undertaken to establish how recycling can be effective in environmental management. The findings emphasise strongly, the high level of awareness that communities have on recycling; however there is a need for intensive resource support for the community initiatives to have the desired impact.

- Description: As the biological databases are increasing rapidly, there is a challenge for both Biologists and Computer Scientists to develop algorithms and databases to manage the increasing data. There are many algorithms developed to align the sequences stored in biological databases - some take time to process the data while others are inefficient to produce reasonable results. As more data is generated, and time consuming algorithms are developed to handle them, there is a need for specialized computers to handle the computations. Researchers are typically limited by the computational power of their computers. High Performance Computing (HPC) field addresses this challenge and can be used in a cost-effective manner where there is no need for expensive equipment, instead old computers can be used together to form a powerful system. This is the premise of this research, wherein the setup of a low-cost Beowulf cluster is explored, with the subsequent evaluation of its performance for processing sequent alignment algorithms. A mixed method methodology is used in this dissertation, which consists of literature study, theoretical and practise based system. This mixed method methodology also have a proof and concept where the Beowulf cluster is designed and implemented to perform the sequence alignment algorithms and also the performance test. This dissertation firstly gives an overview of sequence alignment algorithms that are already developed and also highlights their timeline. A presentation of the design and implementation of the Beowulf Cluster is highlighted and this is followed by the experiments on the baseline performance of the cluster. A detailed timeline of the sequence alignment algorithms is given and also the comparison between ClustalW-MPI and T-Coffee (Tree-based Consistency Objective Function For alignment Evaluation) algorithm is presented as part of the findings in the research study. The efficiency of the cluster was observed to be 19.8%, this percentage is unexpected because the predicted efficiency is 83.3%, which is found in the theoretical cluster calculator. The theoretical performance of the cluster showed a high performance as compared with the experimental performance, this is attributable to the slow network, which was 100Mbps, low processor speed of 2.50 GHz, and low memory of 2 Gigabytes.

- Description: In this research, the objective was to investigate under the chosen liquefaction conditions whether co-liquefaction of coal and microalgae biomass as agglomerates does possess a distinct advantage over the individual liquefaction of microalgae and coal. This was initially done by preparing dry micro algal biomass, followed by the preparation of coal fines and finally coal-algae as agglomerates. The agglomerates were prepared by continuously adsorbing wet concentrated microalgae slurry/solution onto the dry coal fines in order to prepare different ratios of coal-algae agglomerate(s). Ultimate analysis of the starting material (coal fines and the microalgae) as well the agglomerates then followed. According to research, wet microalgae biomass has the potential of acting as a hydrogen donor. By preparing the agglomerates, the rationale was to promote hydrogen supply from the micro algal biomass that has high hydrogen content to the coal with lower hydrogen content. The resulting product was then expected to have fairly higher hydrogen content. However, this was not observed or evident from the elemental analysis results. The results (elemental composition) showed no difference between the agglomerates and the coal. Based on the observed ultimate analysis results, liquefaction experiments were conducted to determine whether hydrogen transfer and the expected synergistic effect between micro algal biomass and coal would occur. The crude oil product was recovered and simulated distillation technique was used for the characterization of the crude oil product. The results we in agreement that higher yields can be achieved during co-liquefaction as compared to the individual liquefaction. A possible synergistic effect that was investigated in this research existed. Liquefaction results provided evidence of higher yields recovery from the agglomerates compared to those of coal fines and microalgae biomass. Although there was higher recovery on the agglomerates, there appears to be a downward trend (decrease) in product recovery with higher loadings of micro algal biomass on to the coal. This means that higher loading of micro algal biomass tend to suppress liquefaction of coal, thus resulting in lower product recovery. While lower loadings tend to effectively facilitate the liquefaction of coal, thus proving that the proposed synergistic effect between the two does exist. Overall product recovery (yields) of the agglomerates is higher compared to the individual recovery of coal fines and microalgae biomass. This was followed by mass balancing to determine the overall conversion. Higher conversions were achieved on the agglomerates compared to coal. This could mean that microalgae have the potential to facilitate the liquefaction of coal and improve its conversion. The observed trend results in improved conversion as well as higher oil yields (simulated distillation results). Overall, the mass balancing provided insightful information regarding the coal-microalgae interaction based on the conversion, and this further corresponds or supports the simulated distillation results. This research paper provides evidence of the synergistic effect that exists between micro algal biomass and coal.

- Description: Indigenous people tend to consult traditional healers when a family member manifests change in behaviour, whilst conventional treatment disregards spirituality when preserving mental health. The aim of the study was to explore the perceptions of indigenous people and the role of traditional healers in the management of mentally ill persons within the Cacadu District in the Eastern Cape Province of South Africa. The study has adopted a qualitative approach which was exploratory and descriptive in nature. The sample consisted of nine relatives of mental health care users (MHCUs) and six traditional healers. Ethical principles were also taken into consideration by the researcher during the process of conducting the study. Data were collected from two strata, namely, relatives of the MHCUs and the traditional healers and an interview guide was used to conduct in-depth face-to-face interviews. Data were analysed using Tesch’s method of data analysis. Four themes emerged from the data categories and sub categories were identified. According to the themes participants indicated the negative impact of mental illness; as a result they portrayed great desperation regarding the means of accessing a cure for mental illness. Some participants showed insufficient knowledge regarding mental illness and had different perceptions and beliefs regarding the origin of mental illness. Available literature was used to emphasise and support the views that were expressed by both traditional healers and relatives of MHCUs. It has been highlighted from this study that indigenous people of Cacadu District view mental illness as spiritual in origin but they include Western medication for the benefit of the mentally ill. In addition, the relatives of the MHCUs highlighted the economic burden as the major problem that results from mental illness.

- Description: The study considered the prevalence of risky sexual behaviour in child headed families that usually affects the adolescents in South Africa. This study aimed at exploring the prevalence of risky sexual behaviour in child headed families, determining the causal factors of sexual promiscuous behaviour and effects of promiscuity. The area of investigation was Qora Village which is in a small town called Idutywa, Eastern Cape. This is an area that is characterised by poverty, illiteracy and unemployment. The sample was comprised of 50 participants and the study was conducted in two phases using mixed methods approach. Social exchange theory underpinned the study. Findings highlighted that these child headed adolescents had a role of caregivers and due to poverty they practiced risky sexual behaviour to bridge the economic gap. Furthermore, teenagers living in child headed families were likely to engage in risky sexual behaviour with people who are older than them; others are forced and coerced; while others perceive such act as a better option to bridge the economic gap that existed within their family backgrounds.

- Description: A general lack of biological information is hampering the effective management of Angola’s fisheries. While this lack of information is largely a result of the country’s extended civil war that ended in 2002, the subsequent rapid expansion of fisheries is most likely impacting fish abundance and influencing the biology of this regions fishes. Besides the influence of fisheries, the southern Angolan coastal region is considered to be a climate change “hotspot” due to rapidly (>0.8°C/decade) increasing water temperatures. These changes are thought to drive further changes to the biology of fishes. It is therefore critical to provide baseline biological information and to identify the impacts of exploitation and warming on the biology of southern Angolan fishes. Pomatomus saltatrix is a warm-temperate marine fish species that forms an important component of fisheries throughout its broad distribution. P. saltatrix is a migratory predator that displays variable growth and maturity schedules. Typically it is heavily targeted in a range of coastal fisheries of Angola and is therefore an ideal candidate to study the biological impacts of exploitation and climate change. The aim of this study was to provide the first description of P. saltatrix biology in Angola and examine recent changes of the species biological parameters in an attempt to uncouple fishery driven from climate driven changes. Samples of P. saltatrix were collected monthly using standardised biological methods from June 2005 to December 2006 (period 1) and from June 2012 to February 2013 (period 2). The average (508mm – 1st period, 462mm – 2nd period) and maximum (760mm – 1st period, 746mm – 2nd period) size of P. saltatrix was smaller during the second period to suggest selective overharvesting of large individuals by developing fisheries. Angolan P. saltatrix grew very rapidly in their first year and thereafter, relatively slowly when compared to other populations globally. However, fish grew faster (ω = 103 – 1st period, ω = 124 – 2nd period), matured at a larger size (303mm - 1st period, 336mm - 2nd period) and younger age (0.83 years - 1st period, 0.67 years – 2nd period) during the second period. Peaks in reproductive activity remained similar (November) during both periods but a temperature anomaly appears to have influenced spawning during period 2. Sardinella aurita was the dominant prey during both periods but a greater dependence upon mugilids was observed during the second period. Although the changes in life history were not statistically significant, the faster growth observed during period two could be attributed to both increasing temperature and/or exploitation. Fishes generally grow faster, mature smaller and attain a smaller maximum size in warmer temperatures. Fisheries targeting small and large specimens of a species (as observed in this study) largely have the same impacts as ocean warming. With rapidly increasing water temperatures and exploitation rates, faster growth and earlier maturation of P. saltatrix populations will mitigate the impacts of exploitation in the short-term. However, the sustainability of Angola’s P. saltatrix stock is questionable as phenotypic adaptation will have a limited thermal scope and overexploitation will, like in all fisheries, negatively influence recruitment. Ultimately, strict monitoring, regulation and control will be necessary to ensure the sustainability of the P. saltatrix resource in Angola as it continues to face increasing anthropogenic and environmental pressures. Management guidelines and future research suggestions are therefore outlined with reference to the results of analyses conducted during this study.

Almost all the machine data contains some element of security information that can be used to discover, monitor and investigate security events.The work proposes a pseudo-random access compressed storage method for log data to be used with an information retrieval system that in turn provides the ability to search and correlate log data and the corresponding events. We explain the method for converting log files into distinct events and storing the events in a compressed file. This yields an entry identifier for each log entry that provides a pointer that can be used by indexing methods. The research also evaluates the compression performance penalties encountered by using this storage system, including decreased compression ratio, as well as increased compression and decompression times.

- Description: The South African automotive industry is by no means a ―cut and paste‖ version of their overseas counterparts. The industry and the market are very complex. The historical background of the industry is such that companies have difficulty forming partnerships and joint ventures with bigger international conglomerates. The difficulty with this kind of mindset is that it is restricting growth and development of the nation as a whole. Globalisation is a future we cannot be avoided. Should the nation continue to reject it and embrace the mindset of countries in Africa, South Africa (SA) will continue on the path that the rest of Africa is heading, a path that leading to self-destruct and segregation. Even though SA is a developing country, it is in some areas as developed as many other first world countries. For a country to generate wealth it needs to be innovative and develop an entrepreneurial consciousness. A young country like South Africa needs creative thinkers and opportunists that can see into the future, seizing every opportunity, to grow and develop new ideas and business. In order for a country to grow it needs a leadership that is to nurture the baby of innovation. If South Africa wants to be part of the global village it need to develop a trade policy that welcomes trade and at the same time creates stable and sustainable jobs. The environment for investments needs to be cultivated in a problem-free and growth prone nation. This can only happen when the educational level of the nation is improved. The fact that so many skilled workers need to be imported creates tension in the labour market. People with talent need to have a reason to stay in the country. Their salaries should match that of their overseas counterparts. Furthermore, with the same skill level and work ethic, should have the same rewards and remuneration.

- Description: Defining leadership effectiveness (LE) remains a controversial subject with scholars and researchers disagreeing on a common definition. Most studies term leadership effectiveness as the leaders’ ability to successfully exercise personal influence and abilities in order to accomplish set standards. Such leadership effectiveness was measured using three elements, namely influence, follow commitment and versatility. To be effective, leaders must possess certain competencies and perform specific tasks (independent variables). In this study, three leadership competencies, namely strategic thinking, emotional effectiveness and transformational leadership were examined. Similarly, seven leadership tasks (set organisational direction, develop human capital, build core competencies, create organisational alignment, sustain appropriate organisational culture, manage change and establish balanced organisational control) were identified as essential for the attainment of leadership effectiveness (intervening variable) which, in turn, leads to organisational effectiveness (dependent variable). Given the importance of leadership effectiveness to organisational effectiveness, the purpose of this study was to identify, investigate and empirically test the possible relationship between leadership effectiveness and organisational effectiveness within the Kenyan indigenous banks. To achieve the aim of the study, a survey was undertaken using a structured self-administered questionnaire. The respondents were identified using both probability and non-probability techniques with the survey yielding 257 usable questionnaires that were statistically analysed. The proposed hypothetical relationship between leadership effectiveness and organisational effectiveness was assessed using Structural Equation Modelling (SEM), a multivariate statistical technique. The SEM included Cronbach’s alpha and confirmatory factor analyses to assess the dicriminant reliability and validity of the measuring instrument, and Goodness-of-fit indices. The study findings demonstrated the existence of a strong relationship between leadership competencies, tasks performed and leadership effectiveness which in turn impacts on organisational effectiveness, in this case the overall effectiveness of the Kenyan indigenous banks.

- Description: This edited work has gathered together contributions on how to transform universities in South Africa; as many are struggling to shift their institutional culture. In a South African context, transformation means to attempt to change higher education institutions such that they no longer reflect the values promoted by apartheid but rather reflect the values embodied in South Africa's 1996 Constitution. Institutional culture is the main subject for discussion in this book. In order to transform South Africa's universities, the contributors begin by analyzing the idea of what a university is, and relatedly, what its ideal aims are. A second theme is to understand what institutional culture is and how it functions. Moreover, transformation cannot occur without transforming the broader cultures of which they are a part. Related to this theme is a general concern about how contemporary moves towards the instrumentalization of higher education affect the ability to transform institutions. These institutions are being pushed to conform to goals that are outside the traditional idea of a university, such as concerns that universities are being 'bureaucratized' and becoming corporations, instead of a place of learning open to all. In conclusion it can be said that the contemporary South African academic community has an opportunity to recreate itself as the end of apartheid created space for engaging in transformative epistemic projects. The transformation of the tertiary sector entails a transformation of institutional cultures.

- Description: Sexual violence is a serious social concern, especially in South Africa. Explanations for high levels of sexual violence often point to normative cultural expectations regarding gendered behaviour. Consequently, attempts to address sexual violence frequently take the form of public health initiatives aimed at increasing awareness of the problem, encouraging reporting and, much more recently, addressing the social attitudes believed to be held by perpetrators of this violence. A common format for such initiatives is anti-rape poster campaigns. This paper argues, through applying Foucauldian discourse analysis to a series of posters, that very often the messages conveyed by these initiatives are addressed at the prohibition of behaviours associated with sexual violence. The analysis shows that this strategy may not be sufficient, and instead argues that alternative strategies - aimed at inviting audiences to take up an ethical position - may be more effective at producing change.

- Description: The aim of this study was to conduct a comparative analysis of the low voter turnout of the 2006 and 2011 municipal elections in Lukhanji Municipality. The study came as a result of the researcher’s observations of the low voter turnout during the 2011 municipal elections across the country. Upon further investigation, it was discovered that the previous municipal election of 2006 also experienced low voter turnout. However, this was not the case with national and provincial elections, because since the first election that took place in 1994, voter turnout has been high. Lukhanji Municipality, which is the area of residence for the researcher, was no different from the rest of South Africa, when it comes to low voter turnout for the municipal elections and high voter turnout for national and provincial elections. It was noted that there has never been a detailed research study conducted in Lukhanji Municipality regarding the subject in question, and also that there is a limited amount of literature that seeks to investigate voter turnout in local elections in South Africa. The large amount of available literature focuses on voter turnout during national and provincial elections in established democracies. The literature review extensively explored the determinants of voter turnout in all levels of elections. From those tested elsewhere, it was evident that no single factor can be the cause of low voting during an election, therefore it was fundamental to investigate the causes of low voter turnout of the municipal elections with special focus on Lukhanji Municipality. It became evident from the study, that indeed various factors may have led to low voter turnout during 2006 and 2011 municipal elections in Lukhanji Municipality.

- Description: This research attempts to evaluate the stability of money demand functions and estimate monetary inflation models in the East African Community (EAC), using quarterly aggregate data that range from 2000Q1 to 2012Q3. We used Johansen co-integration analysis to estimate and analyse the stability of the M3 money demand model for each country member of the EAC. From this estimation, we derived a country-specific measure of money overhang. We compared its forecasting power of future inflation with that of money stock growth, and money stock available in the economy. Regarding country-specific money demand functions, with the exception of Uganda, we identified a reasonable and stable country-specific M3 money demand model. Also, for predicting future inflation, the estimation results showed that M3 money stock growth is more reliable in Burundi and in Kenya, while M3 money overhang is preferable in Rwanda and M3 money stock in Tanzania. As both country-specific and regional (EAC area) information on monetary quantity growth and its impact on price level is important to know in a monetary union, we considered the EAC area as a single market and attempted to estimate the aggregate (EAC area) demand functions for broad money M2 and M3 using Johansen co-integration analysis. The estimated long-run aggregate money demand models M2 and M3 appeared to be stable over the sample period. However, the aggregate M2 and M3 at the EAC level were proven to be weakly exogenous, which should discard them for consideration at the EAC level as the intermediate targets variables in order to achieve the overall objective of price stability in the EAC region. Instead, short-term interest rate should be given a prominent role in monetary policy framework at the EAC level.

- Description: The rise of microfinance in South Africa as a development trajectory has dismissed ideas that small business enterprises have no significant contribution to the economic growth and development of the country. The primary objective of the study is to assess the impact of microfinance service providers on the success and sustainability of small business enterprises in the Nelson Mandela Bay. By applying descriptive statistics, 2 ordinary least square regression analyses as well as correlation matrix; the results reveal that microfinance has a positive and significant impact on the success and sustainability on small business enterprises in the Nelson Mandela Bay. The research findings hold a variety of implications for Government and policymakers. The study recommends that the microfinance sector must be under good governance through the microfinance regulatory and supervisory structures, since the sector contributes a great deal towards one of the most important objectives of the Post-Apartheid Government. Further, small business entrepreneurs must be well exposed to the requirements, standards and norms which govern the financial sector. This is particularly important in terms of the National Credit Act provisions.

- Description: Cooperatives have principles and goals that regulate their day-to-day operations. Their aim is to create jobs through carrying out income generating projects. This aim is usually difficult to achieve as ‘human’ factors sometimes obscure the projects’ progress. This study therefore explored the nature of relationship that exists between the University of Fort Hare (UFH) and the cooperative members involved in the project, which in this study are referred to as, Ilima Agripark Project (IAP) members. This relationship was investigated through the three particular forms (information, consultation and participation) of community engagement, their nature, meanings, the influence they possess and how IAP/UFH members comprehend these. Guided by her research matrix and interview guide, the researcher used the qualitative and interpretive approach method to collect data. The case study made use of document analysis, key informant interviews, direct observations, face to face interviews and focus group discussions to collect data. In order to validate her data, she also made use of a tape recorder and notebook. The study’s key finding is that the three particular community engagement forms are not fully utilised by the university. The study revealed that there is lack of transparency when it comes to information dissemination hence, the IAP members feel insecure and socially excluded.
