- Description: Pension funds are the principal sources of retirement income for millions of people in the world. Pension funds are also important contributors to the gross domestic product (GDP) of countries. This study focuses on pension funds in Kenya. Retirement income accounts for 68 percent of the total income of retirees in Kenya, while pension assets account for 30 percent of Kenya’s GDP. It is therefore important that pension funds be managed effectively, not only in Kenya, but also in other countries. The primary objective of the study is to investigate ways of enhancing pension fund efficiency by establishing the determinants of such efficiency. More specifically, the study explores the effect that the organisational culture, regulations, investment strategy, ethics, risk management, design, size and the age profile of members of pension funds exert on the efficiency of these funds. A sample of 749 pension funds was drawn from the Kenyan Retirement Benefits Authority (RBA) register. The sample selection was based on the criterion that these pension funds should have been in existence within the period 2001 to 2008. Seven hundred and forty-nine (749) questionnaires were mailed to the trustees of these pension funds. Three hundred and sixty-two (362) usable questionnaires were returned, which translated into a response rate of 48.3 per cent. Except for financial efficiency, self-constructed instruments based on secondary literature reviews were used to measure the variables in the hypothesised model to improve pension fund efficiency. Appropriate steps were taken to ensure the validity and reliability of these measuring instruments. The empirical results revealed that leadership, governance, regulations, design, membership age and size of funds had no significant influence on operational efficiency of these funds. The results further showed that the membership age, design, regulations and operational efficiency of pension funds exerted no significant influence on their financial efficiency. The results also revealed that the membership age, size and design of pension funds did not influence how these funds were led by their leadership. iv The empirical results however showed that smaller pension funds were perceived to exhibit better financial efficiency, while pension funds with membership aged 31 - 40 were perceived to be better governed compared to other age groups. Finally, in rigorous structural equation analyses, no significant relationships were found between fund regulations (independent variable), on the one hand, and fund governance and leadership (dependent variables), on the other hand. Use of simple linear regression however disclosed a significant positive relationship between the afore-mentioned independent variable and dependent variables.

- Description: Type I hypersensitivities are mediated by the IgE antibody. The effector functions and synthesis of IgE result from interactions with a network of proteins that include a high affinity (FcRIα) and a low affinity (CD23, FcRII) Fc receptor in conjunction with the B lymphocyte receptor, CD21. CD23 is a multifunctional type II transmembrane protein that binds its known ligands through its ectodomain either as a membrane-bound or soluble receptor generated in vivo by specific proteolytic cleavages. IgE production is primarily regulated by interactions between IgE, CD23 and CD21. Despite its importance for development of strategies to limit hypersensitivity, precise information about the molecular interactions remains limited. During this study, I engineered, expressed and purified from bacteria three soluble human CD23 fragments that are normally formed in vivo and shed from the cell surface (1) derCD23, amino acids 156-298 (2) sCD23, amino acids 150-321 and (3) the entire ectodomain, exCD23, amino acids 48-321 to examine the comparative binding of recombinant human CD21 SCR 1-2 and native human IgE to these fragments. Gel filtration HPLC revealed that derCD23 and sCD23 were monomeric whereas exCD23 assembled as a heterogeneous mixture that included trimers and monomers. At the concentrations utilized, CD23 fragments sCD23 and exCD23 bound CD21 with similar affinity, whereas interaction between derCD23 and CD21 was minimal when analyzed by surface plasmon resonance (SPR) spectroscopy. These findings suggest that penultimate “tail” amino acids between 298 and 321 stabilize CD21 attachment, although it cannot be ruled out, the region between Met 150 and Ser 156 may also play a role in binding CD21 SCR 1-2. In contrast, there is a progressive increment in the affinity of soluble fragments (exCD23>sCD23>derCD23) for IgE, upon increasing length of the proximal CD23 “stalk” domain. These findings highlight the differences in both the structural basis and affinity of the three physiological fragments of human CD23 for the ligands CD21 and IgE and underscore the complexity of CD23-mediated regulatory networks. It was found that B-cells only make up ~5% of the PBMC population, and that these cells were able to be activated, via STAT-6 phosphorylation, to enter class switch recombination (CSR) by the addition of switch factors (IL-4 and anti-CD40). Titration experiments dictated that 25 ng/mL of CD23 was the most efficient concentration to up-regulate IgE synthesis in PBMCs; furthermore, soluble CD23 proteins were incubated with PBMCs in the presence and absence of CD21 SCR 1-2 to investigate the effect that these recombinant proteins have on IgE synthesis. Results showed that the influence of recombinant proteins (both CD23 and CD21) on IgE synthesis was slight. It was shown that while derCD23 had no significant effect, monomeric sCD23 down-regulated, and the mixture of monomeric and oligomeric exCD23 up-regulated IgE synthesis. On addition of CD21 SCR 1-2 to the cells switched and treated with soluble CD23, it was found that in both cases for sCD23 and exCD23, IgE synthesis was increased, while for derCD23, there was no noticeable difference in IgE synthesis. This confirmed previous data showing the lack of binding between derCD23 and CD21 SCR 1-2. The exact binding site for CD21 on the CD23 molecule is unknown, and incompletely represented in the NMR and crystal structures. It is thought that CD21 binds to the C-terminal tail section, not present in derCD23. It is therefore likely that only a negative-feedback mechanism operates with derCD23 to regulate IgE synthesis. Further investigation of the binding of CD23 fragments to SCR 5-8 of CD21 and the effect of this on IgE synthesis may lead to a potential therapeutic role for derCD23 in the treatment of allergic disease. Data accumulated in this study suggests that investigating the modulation of oligomeric state and thus the activity of soluble CD23 fragments may be important in the construction of new regulators of IgE synthesis.

- Description: This treatise will focus on a critical examination of Gavin Hood’s South African Oscar-winning film, Tsotsi (2006), in the interest of exploring how the mass media creates a problematic configuration of the subject, in virtue of its valorization of the continued discursive colonization of Africans (identified broadly in geographical rather than racial terms). That is, within the narrative of the film, the protagonist, after engaging in a crime spree, gives himself over to the state authorities and emotively confesses to his transgressions. Importantly, this dramatic confession is represented as a triumph of the human spirit – in the form of an autonomous rehabilitation on the part of the criminal. However, if one understands the protagonist as a subject constituted by what Foucault terms the discursive regimes of disciplinary/bio-power, what emerges into conspicuity is that the protagonist’s actions rather than being the result of his growing maturity and concomitant augmenting ‘humanity’ are the consequence of a set of discursive imperatives which render him docile and prostrate. Arguably, what this serves to represent, and, indeed, propagate, is more of a superimposition of Western cultural discourses on African subjects, and less of a negotiation with such discourses by such subjects. The treatise aims to provide a theoretical solution to the negation of alternative modes of being by disciplinary/bio-power imperatives inextricable from neo-liberal subjectivity. However, in its attempts to encourage cultural negotiation between North and South, the treatise will avoid simplistic, ‘orthodox’, Marxist solutions and will instead critically contend with the theory of Ernesto Laclau and Chantal Mouffe, and their perspectives on how radical democracy can be achieved.

- Description: In the 1990s, Susan Faludi’s Backlash: The Undeclared War Against Women (1992) was arguably of signal importance in the thematization of the limits imposed by the media on the negotiation of gender identity. However, the utilization of Faludi’s various analyses, in the interest of rendering social critique, has become progressively more problematic during the first decade of the 21st century. This is because her analyses engage neither with the development of media technologies subsequent to the early 1990s, nor with the way in which such technological developments now engage audiences on a greater multiplicity of levels than before, in a manner that consequently stands to inform their subjectivity to a degree hitherto unimagined. (A good example of the latter would, of course, be the proliferation of interactive exchanges on the World Wide Web). As such, in the light of such technological developments, this treatise is orientated around an investigation of the continued relevance of Faludi’s Backlash (1992) for the negotiation of gender identity in the contemporary era. In particular, its focus falls on West’s film Lara Croft: Tomb Raider (2001), which is considered against the backdrop of the Lara Croft: Tomb Raider phenomenon, which encompasses sequels to the film, online interactive sites, graphic novels, figurines, and video games, among other products. This investigation draws on the reception theory of, on the one hand, Adorno and Horkheimer, and, on the other hand, Stuart Hall.

- Description: The purpose of this study was to investigate the role played by records management in an organisation. The primary question that was explored was whether the management of records receives the attention it deserves at the Amathole District Municipality. In order to achieve the research objectives, an in-depth literature study was undertaken. A survey was also conducted to examine the current records management practices at ADM and the data was collected by means of self-administered questionnaires. The literature study proved the hypothesis to be correct, which stated that effective records management plays a significant role in the effective administration of an organization. The empirical study revealed that the records management function is not receiving the attention it deserves at ADM. Even though participants acknowledged the importance of records management in the decision-making process, strategic planning process (Integrated Development Plan), the realisation of the Batho Pele Principles and the overall performance of ADM, it was evident that ignorance was displayed with regard to the management of records. It has been discovered that Amathole District Municipality has a good Records Management Policy, Procedure manual and File Plan, but adherence to these policies should be continuously monitored. Regular training has been identified as one of the areas on which ADM should apply its focus to ensure sound records management. Recommendations were made within the context of empirical survey findings and the regulatory framework for records management. To improve the current records management practices at ADM, it has been recommended that the records management function be incorporated into the organisation-wide strategic plans and that records management forms part of the key performance areas of senior managers.

- Description: This study investigated the role of selected ward committees 29 and 32 of Nompumelelo and Tsholomnqa respectively in the Buffalo City Municipality (BCM) in enhancing basic service delivery. In terms of the White Paper on Local Government (1998:4), developmental local government promotes a system that centres on working with local communities to find sustainable ways to meet their needs and improve the quality of their lives. The study on that basis examines the nature and extent to which wards 29 and 32 committees enhanced basic service delivery within BCM. The study is premised on the assumptions that: The involvement of party-elected Councillors in ward committees inhibits members of ward committees from playing an active role in their communities; Ward committees are not clearly communicating municipality programmes to their communities; BCM is biased in favour of urban wards in service delivery; If the committees of wards 29 and 32 were given more powers to play a much wider role in providing leadership and make decisions in their communities (being elevated from an advisory role to ward management structures), they would make an impact in enhancing basic service delivery; and, With additional decision-making powers ward committees could play a more effective role in local government matters. The perceived slow pace of service delivery by municipalities has resulted in growing impatience and dissatisfaction, in particular among poor communities. This has been demonstrated by the spontaneous protests and unrests directed at municipalities that have been taking place nationally since 2003. The uprisings explain two aspects, namely local government is considered by communities to be the delivery arm of government in South Africa and poor communities feel betrayed because their active participation in government-provided spaces for participation such as municipal elections, ward committees and IDPs did not yield the result of promised development (Theron, 2008:36). iv The study employed the qualitative research design using an interview survey as a method of data collection and the reviewing of existing study material and documents to test the validity of the afore-mentioned assumptions. Lastly, with the aim of assisting BCM in nurturing the potential of ward committees operating in its area of jurisdiction, the following recommendations based on the findings of the study are made: BCM considers subjecting ward committees to structured formal and accredited training; BCM delivers services in a legally compliant manner; BCM delegates sufficient powers to ward committees; Ward committees be trained together with officials that drive the CBP process when BCM starts implementing the process; and, BCM provides support to ward committees.

- Description: This research study aims to investigate the South African Land Reform process from a conflict resolution perspective. According to Burton’s basic human needs theory deep-rooted social conflict will occur wherever social institutions neglect universal basic human needs. Excess to land and land tenure are considered basic human needs because they provide landowners with food, shelter and security. In absence of an extensive welfare state, land ownership fulfils the role of a social safety network, particularly in African countries. Consequently, an equal distribution of land is needed in order to enable the majority of South Africans to fulfil their basic human needs. The instrument chosen for correcting the inequalities in land distribution are the three components of the South African land reform programme namely tenure reform, restitution and redistribution. The South African Land Reform Programme was largely influenced by the World Bank’s ‘Willing-Seller Willing- Buyer’ or ‘Negotiated Land Reform Approach’. Nevertheless, the South African model differs from the original concept by the World Bank in some aspects. The outcome of the Land Reform Process is analysed and evaluated by the on-going evaluation approach. All sources used in this research are open to the public and published either on official websites or in hard cover version in reports and articles. The results of this investigation indicate that the target of redistributing 30% of white-owned agricultural land by the year 2014 is not going to be accomplished. Nevertheless, the settlement of claims can be considered a success story although most of the claims were settled by means of cash compensation instead of actual land transfer. Furthermore, a change in the land acquisition policy from a demand-led approach based on the negotiated land reform principle towards a more static, state-led, top-down approach has been identified as well as shortcomings in the post-settlement support of new landowners. To put it briefly, the land reform process in toto is about to fail and a chance of reducing the enormous conflict potential given away. Furthermore, the conflict potential will increase due to the failures in providing the poor and rural masses with access to land.

- Description: This research study aims to investigate the South African Land Reform process from a conflict resolution perspective. According to Burton’s basic human needs theory deep-rooted social conflict will occur wherever social institutions neglect universal basic human needs. Excess to land and land tenure are considered basic human needs because they provide landowners with food, shelter and security. In absence of an extensive welfare state, land ownership fulfils the role of a social safety network, particularly in African countries. Consequently, an equal distribution of land is needed in order to enable the majority of South Africans to fulfil their basic human needs. The instrument chosen for correcting the inequalities in land distribution are the three components of the South African land reform programme namely tenure reform, restitution and redistribution. The South African Land Reform Programme was largely influenced by the World Bank’s ‘Willing-Seller Willing- Buyer’ or ‘Negotiated Land Reform Approach’.

- Description: This study aimed to provide South African public relations professionals with insights into the use of the Social Media News Release (SMNR) as a PR 2.0 tool that has the potential to elicit consumer-driven dialogue in social media channels about information, a brand, product or service advocated by the particular social media news release. Drawing on literature from fields such as public relations, new media studies, marketing, and consumer studies, an analysis of two South African SMNR case studies was conducted including the Samsung Omnia i900 SMNR and the Standard Bank Pro20 2008 and 2009 SMNRs. An in-depth content analysis applying limited designations analysis and detailed assertions analysis techniques was performed on selected content from the dedicated social media platforms linked to in the SMNRs to determine the origins, tone and thematic nature of communications on the platforms. A total of 2071 messages was analysed by means of content analysis across six social media platforms in the two case studies. In order to triangulate and support data, an online survey was conducted with 43 social media users as respondents in order to determine social media users’ interactions with the social media platforms and SMNRs. The study found that the social media platforms linked to the SMNRs in the two case studies largely successfully elicited and hosted social media user-generated conversations about the themes advocated by the SMNR. The Blog, Facebook and YouTube platforms proved to be most successful in generating social media conversation, while the Flickr, Twitter and Delicious platforms were less effective among South African consumers. It was found that social media news releases are likely to elicit consumer-driven dialogue on the dedicated social media platforms linked to by the SMNRs if the platforms are managed correctly. Factors that were identified as important management considerations include ensuring the relevancy and timeliness of content on the social media platforms, the involvement by the platform creator in stimulating and encouraging participation from social media users where necessary, as well as the swift response to user comments, deleting of spam comments and pro-active management of negative perceptions that may arise from user comments on the platforms.

- Description: This study investigated the effectiveness of Ward Committees in co-ordinating and facilitating authentic public participation processes at local government levels. This study focused specifically on the Knysna Local Municipality. Before 1994 the majority of South Africans had never had the vote, and therefore, had not had the opportunity of participating in South Africa’s governance and administration (Hilliard and Kemp, 1999:40). In this governance system, local government was the lowest tier of government in a strict hierarchical structure; and it had no constitutional standing of its own, but derived its powers from the two superior tiers of government, namely national and provincial. The local government elections of 5 December 2000 in South Africa provided municipalities with a historic opportunity to transform local government to meet the needs of the country for the next century. The local government transformation process (in tandem with the demarcation process that established the new municipal boundaries) introduced more developmental responsibilities to municipalities. In addition, this further implied that local government became an autonomous sphere of government with its own original powers and a broad developmental mandate. This had profound implications for local governance. An important element of the current local government system is the promotion of local democracy and participation in local governance. Public participation is an integral part of local democracy and is a legislative requirement for the local community to be drawn into the v municipal processes through inter alia: Integrated Development Planning (IDP), budgeting, performance management and Ward Committees. Although the ‘old’ South African local government system did not have an extensive history in ensuring a culture of actively engaging communities in developmental issues, the IDP under a Developmental Local Government (DLG) system now presents a framework through which such a culture can be established. The Ward Committees in particular, play a critical role in linking community needs with municipal planning processes. In South African local government the commitment to public participation is reflected in a host of laws and policy documents (namely the Local Government: Municipal Systems Act 2000 (Act 32 of 2000), Local Government: Municipal Structures Act 1998 (Act 117 of 1998), the Constitution of the Republic of South Africa , 1996). These laws and policies are intended to be realised through development initiatives that require formal participatory processes and institutions in local governance. Since 2001 Ward Committees have emerged as a key institutional mechanism intended to contribute towards bringing about people-centred, participatory and democratic local governance. The rationale for Ward Committees is to supplement the roles of the elected Ward Councillors by creating a link between communities and the political and administrative structures of municipalities. These Ward Committees have been established in the majority of wards in municipalities across the country in line with the vi requirements of the Local Government: Municipal Structures Act,1998 (Act 117 of 1998) which stipulates that: Only metropolitan and local municipalities of certain types may have Ward Committees. The main objective of the study was to investigate the overall functioning of Ward Committees within the Knysna Local Municipality and to determine their impact on democratic local governance thus far. The study will carry out an investigation into the effectiveness of Ward Committees: whether they are useful conduits for public participation in local governance; whether they are inherently capable of playing the critical role expected of them; and whether they actually create opportunities for real power-sharing between the Knysna Local Municipality and its communities. The study’s main objective stated above was achieved by breaking it down into realisable objectives, namely: • A brief background of the Knysna Local Municipality, and in particular, an outline of its institutional arrangements and its Ward Committees in general. • An evaluation of the theoretical and legislative framework of public participation and the Ward Committee System in local government. • An analysis of the practical performance of Ward Committees in the Knysna Local Municipality and to provide a research report on the empirical findings. • Recommendations aimed at improving the effectiveness of Ward Committees at local government levels in general, and in particular, in the Knysna Local Municipality. The hypothetical position of this study was that the maximum utilisation of Ward Committees as a means for public participation processes at local government levels, specifically in the Knysna Local Municipality, could improve communication between local municipalities and the public. Furthermore, this would also contribute towards the speedy delivery of services to communities, as Ward Committees could serve as the Local Municipality’s strategic partners in Council’s projects. Ward Committees should therefore be utilised to enhance a constructive interaction between a municipality and its local community. This position was premised on the fact that authentic and empowering participation can be established at local government levels if Ward Committees act as a foundation for development and Ward Committee Members as development change agents in their respective wards

- Description: Property development, by its very nature is an element of the economy and can be regarded as a multifaceted business, encompassing activities that include the development of undeveloped land by constructing residential, commercial and industrial buildings, either for leasing or selling. Based on the aforesaid, property development therefore has direct, indirect and induced impacts on the economy. Economic impact refers to the effects, positive or negative, on the level of economic activity in a given area. Measuring economic impact requires a baseline assessment conducted before the activity (property development) occurs and a second, comparable assessment conducted after the activity (property development) occurs. By using the Input- Output Model methodology, various anticipated direct and indirect economic impacts can be quantified. These economic impacts are derived using an understanding of economic cause-effect relationships. The principle of cause-effect is that for any economic action, there can be a multitude of different economic reactions (effects). For the purposes of this treatise, the main cause/action is the implementation of the proposed Alphen Aan Den Rijn Retirement and Lifestyle Village development in Oudtshoorn. The result is a number of direct potential/probable effects, which also have a range of indirect potential/probable effects. Based on the findings of the Input-Output Model, it is clear that the implementation of Alphen will have significant positive socio-economic benefits, e.g. additional business sales, additional GGP and additional employment for the local and regional environment. To ensure that these positive impacts are maximised for the benefit of the overall economy of Oudtshoorn as well as the population of Oudtshoorn, management strategies and mechanisms pertaining to the following are suggested for incorporation into the development proposal: • Workplace Skills Plan; • Labour Contracts; • Service Carrying Capacity Management Plan; • Economic Sustainability; and • Social Sustainability.

- Description: Game ranching offers an economic alternative to conventional stock farming and is a means of supplementing income derived from agricultural activities. Competition is intensifying as ranchers continuously look for ways to improve and expand their businesses and gain a competitive advantage. Ranchers consequently have to find strategies that can ensure growth. Since a reciprocal relationship and dependency exists between a game ranch and the environment in which it operates, it is essential that ranchers take cognizance of aspects in the marketing environment that can either limit, and hence encumber the choice of growth strategy, or stimulate the growth potential of game ranches. As the objective of marketing is to offer customers superior value, it is pertinent for ranchers to know and understand the needs, requirements and motivations of visitors. Failure to do so will cause visitors to patronise other game ranches, or alternative tourism offerings that meet their expectations. A literature review was conducted to define strategy and assist in identifying growth strategies available to a game ranch. The literature review assisted in categorising elements in the external, internal and customer analysis phases of strategic marketing management. Surveys were conducted by means of self-completion questionnaires which were distributed throughout South Africa. Two sets of questionnaires were distributed - one to respondents with prior experience of a game ranch, and one to respondents with no-prior experience. A qualifying question directed the fieldworker to decide which questionnaire should be completed by the respondent. The surveys were constructed in such a way as to determine to what extent various factors would persuade respondents to visit a ranch or extend their stay. Based on a factor analysis, an eight factor structure emerged which represented the personal values of respondents and their levels of expectation for each of the factors. The eight factors were stimulation, universalism, tradition, security, hedonism, power, socialisation, and self-direction. The study revealed the following. - The majority of respondents with no-prior experience of a game ranch is either unaware of the offerings of game ranches, or perceives them as too expensive. - The sustainable use of natural resources is not only essential for the existence of a game ranch, but is also an important motivator for respondents to either visit a game ranch or extend their stay at a ranch. - Staff play a critical role in the overall experience of visitors and act as an important motivator to either visit/revisit a game ranch or extend their stay at the ranch. - Clean and comfortable overnight facilities are deemed important by all respondents. - Respondents have a strong desire to relax and spend time with family and friends. A decision-making framework from which game ranches can select applicable growth strategies resulted from the study. The decision-making framework comprises a three-phase process; phase 1 is the identification of a game ranch's target market; phase 2 is the use of a simplistic framework to determine a possible growth strategy for a game ranch; phase 3 is the identification of ways to implement the selected strategy. As the game ranch industry makes significant contributions to the economic, social and ecological welfare of South Africa, this study added to the body of knowledge of game ranching in South Africa, particularly with regard to the growth options available to game ranches. Recommendations for consideration of future research included the following. - As the current study investigated hunting and tourism, future research on growth strategies for game ranches could also include other aspects of game ranching such as the sale of live game and game products. - More focused empirical research into external and internal strategic analysis should be considered to supplement the empirical research into customer analysis resulting from the current study. - Finally, additional information obtained on the external and internal strategic analysis process could lead to expanding the decision-making framework developed in this study into a more holistic tool to be used in selecting a growth strategy, or combination of strategies for a game ranch3.

- Description: In the last decades, there has been an escalating consumption of antibiotics with the number of antibiotic prescriptions increasing worldwide. Overuse or inappropriate use of antibiotics has resulted in a major increase in the development of multi-drug resistant pathogens. Antimicrobial resistance is one of the world’s most serious public health problems with great implication in terms of morbidity, mortality, and costs. To date, there has been no formal antibiotic use study conducted in the West Wollega zone of Ethiopia to assess antibiotic utilization. The objective of this study was to determine the pattern of antibiotic use in two hospitals in the West Wollega zone of Ethiopia, namely Gimbie Adventist Hospital and Nedjo Hospitals, using drug utilization metrics and the costs associated. In addition it was to assess the correlation between diagnosed infectious diseases and antibiotic prescriptions. This study was a cross-sectional, retrospective, descriptive review of antibiotic usage in the two hospitals in the year 2007. Prescriptions dispensed in the first month of each quarter of 2007 were reviewed. The number of prescriptions screened, antibiotic courses started, antibiotic days by specific agent and overall, the cost of individual and all antibiotics, the number and type of infectious diseases diagnosed were collected from which core drug use indicators were calculated. The correlation between infectious disease diagnosed and the antibiotic days prescribed were analyzed. A total of 18568 antibiotic and non-antibiotic prescriptions were reviewed retrospectively in the four months of the study period, 47 percent of which contained at least one antibiotic. The average number of antibiotics per prescription was 1.33 and 1.09 whilst the percentage of injectable antibiotics prescribed was 83.2 percent and 3.76 percent to outpatients and inpatients respectively. Antibiotics prescribed from the Essential Drug List (EDL) and List of Drugs for District Hospital (LDDH) were 63.0 percent, 74.8 percent, and 90.8 percent and 76.1 percent for outpatients and inpatients respectively. 98.6 percent of outpatient and 97.0 percent inpatient prescribed antibiotics were actually dispensed. Penicillins and quinolones were the most prescribed antibiotics in both inpatient and outpatient departments constituting 43.46 percent and 24.08 percent respectively. The antibiotic utilization ratio, incidence of outpatient antibiotic use, incidence of inpatient antibiotic use, the number of Defined Daily Doses (DDD)/1000inhabitants/year and DDD/100 Occupied Bed Days (OBD) for the zone was 0.16, 17.25, 23.56, 158.61, and 70 respectively.

The correlation between infectious diseases diagnosed and antibiotic prescription shows significant variation. At outpatient departments alone an average number of antibiotic courses started was 2.7 at Gimbie Adventist Hospital and 7.6 for Nedjo Hospital.

- Description: In the last decades, there has been an escalating consumption of antibiotics with the number of antibiotic prescriptions increasing worldwide. Overuse or inappropriate use of antibiotics has resulted in a major increase in the development of multi-drug resistant pathogens. Antimicrobial resistance is one of the world’s most serious public health problems with great implication in terms of morbidity, mortality, and costs. To date, there has been no formal antibiotic use study conducted in the West Wollega zone of Ethiopia to assess antibiotic utilization. The objective of this study was to determine the pattern of antibiotic use in two hospitals in the West Wollega zone of Ethiopia, namely Gimbie Adventist Hospital and Nedjo Hospitals, using drug utilization metrics and the costs associated. In addition it was to assess the correlation between diagnosed infectious diseases and antibiotic prescriptions. This study was a cross-sectional, retrospective, descriptive review of antibiotic usage in the two hospitals in the year 2007. Prescriptions dispensed in the first month of each quarter of 2007 were reviewed. The number of prescriptions screened, antibiotic courses started, antibiotic days by specific agent and overall, the cost of individual and all antibiotics, the number and type of infectious diseases diagnosed were collected from which core drug use indicators were calculated. The correlation between infectious disease diagnosed and the antibiotic days prescribed were analyzed. A total of 18568 antibiotic and non-antibiotic prescriptions were reviewed retrospectively in the four months of the study period, 47 percent of which contained at least one antibiotic. The average number of antibiotics per prescription was 1.33 and 1.09 whilst the percentage of injectable antibiotics prescribed was 83.2 percent and 3.76 percent to outpatients and inpatients respectively. Antibiotics prescribed from the Essential Drug List (EDL) and List of Drugs for District Hospital (LDDH) were 63.0 percent, 74.8 percent, and 90.8 percent and 76.1 percent for outpatients and inpatients respectively. 98.6 percent of outpatient and 97.0 percent inpatient prescribed antibiotics were actually dispensed. Penicillins and quinolones were the most prescribed antibiotics in both inpatient and outpatient departments constituting 43.46 percent and 24.08 percent respectively. The antibiotic utilization ratio, incidence of outpatient antibiotic use, incidence of inpatient antibiotic use, the number of Defined Daily Doses (DDD)/1000inhabitants/year and DDD/100 Occupied Bed Days (OBD) for the zone was 0.16, 17.25, 23.56, 158.61, and 70 respectively. Antibiotic cost constituted 33.7 percent of all expenditure on drug, cost of antibiotic per patient care day and cost per antibiotic day was 3.84 Ethiopian Birr (ETB) ($0.40) and 6.29 ETB ($0.66) respectively.

- Description: Bacterial resistance to antibiotics has been a great problem for many years. The degree of resistance and the speed with which resistance develops varies with different organisms and different drugs. Enzymes called β-lactamases are produced by bacteria and are one mechanism in which bacteria develop antimicrobial resistance. Gram-negative bacteria producing enzymes called ESBLs because of their wide substrate range are of a particular concern in nosocomial infections. In many countries people still use traditional medicine derived from plants as an alternative to the Western medicine due to increased cost of Western medicine and microbial resistance of antibiotic treatments. Biologically active compounds isolated from plants species are used in herbal medicine. Because of the high prevalence of the ESBLs and their increasing resistance to the antibiotics, this research study was done to test the antimicrobial activities of selected medicinal plants of the Eastern Cape; G. incanum, D. angustifolia and E. autumnalis which were traditionally used to treat various infections. The in vitro antimicrobial activity of three different extracts (acetone, methanol & distilled water) and the traditional preparations of the three plants were tested against the selected strains of ESBL-producing bacteria, non β-lactamase producers and the different fungal species. The extracts were screened against 26 Gram-positive bacterial strains, 53 Gram-negative bacterial strains and 15 fungal strains. The Gram-positive bacteria included strains from S. aureus, B. cereus and E. faecalis. The Gram-negative bacteria included strains from E. ii coli, E. cloacae, K. pneumoniae, P. aeruginosa and Acinetobacter spp. The fungal strains included 9 strains of Candida albicans and a single strain of each of the following opportunistic fungi, Mucor sp, Geotrichium sp, Penicillium sp, Fusarium sp and Rhizopus sp. The agar dilution assay was used for the antimicrobial screening of the plants extracts and for the determination of the MICs. The Ames test was performed for the determination of probable carcinogenicity of the extracts of G. incanum and D. angustifolia. The distilled water extracts followed by acetone extracts of the plants revealed the highest antimicrobial activity against the different microbial strains. The extracts of G. incanum followed by the extracts of D. angustifolia inhibited the highest number of microbial strains. The extracts of E. autumnalis did not show any antimicrobial activity against all the pathogens in this study. More of the Gram-positive bacteria were inhibited by the plant extracts. The lowest MIC was obtained with Gram-positive bacteria. The bacterial strains of E. faecalis and P. aeruginosa were not inhibited by any of the plants extracts in the agar dilution assay yet Acinetobacter species which are MDR were inhibited by the distilled water and methanol extracts of G. incanum. A single strain of Mucor sp was the only spore forming fungi that was inhibited by the distilled water extracts of G. incanum. None of the plants extracts showed any mutagenic effects on the TA100 S. typhimurium strains incorporated on the Ames test. Apart from revealing of new antimicrobial agents that may be used against resistant organisms, the proper use of antimicrobial agents should be recommended. The study has highlighted a need for further investigations on the properties of the medicinal plants used in this study.

- Description: Economies worldwide have become more integrated and competitive due to the phenomenon of globalisation and its antecedents, which are improved technological communication, the use of technology in production, ever improving management of skills as well as standards of education. Amongst the consequences have been changing demands and rising expectations in terms of employee remuneration, job security and conditions of work. This has at the same time been accompanied by employers expecting greater profit. Against this backdrop, this treatise seeks to interrogate and to explain the processes that should constitute fair, rational and justifiable employee dismissal for operational purposes. This is done bearing in mind the global economic crisis and its impact on employees. The treatise constitutes an attempt to carve a cushioning mechanism for employees in the midst of the global economic storm. We consider the inadequacies of common law principles. We also submit that section 189 in its present form and its application by courts do not provide for substantive fairness interrogation when dealing with dismissal for operational reasons. We explore the legislative framework, interpretation by leading academics as well as applications by courts of section 189A, which prescribes that if dismissal is based on operational reasons, consideration must not only be based on substantive and procedural fairness but also that proper consideration of alternatives must have been explored before dismissal is effected.

- Description: Competitiveness is crucial to achieving solid future national economics. A nation’s competitiveness reflects the extent to which it is able to provide increased prosperity to its citizens. Competitiveness can be defined to include the level of productivity of a country. This, in turn, sets the sustainability level of prosperity that can be achieved by an economy (Porter & Schwab, 2008). President Mbeki stated in the 2004 State of the Nation Address that “(South Africa) must continue to focus on the growth, development, and modernisation of the First Economy” (National Research Foundation, n.d.). The National Research Foundation (n.d.) claims that knowledge, innovation, and productivity, as well as optimal use of resources in the enterprise, are key to a competitive, sustainable growing economy. Firms involved in lean manufacturing do so to improve overall company performance in terms of productivity, efficiency, profitability and reducing costs. More than 90 per cent of these firms claim to be successful in achieving such goals. There is a clear association between the use of lean manufacturing and achieving higher productivity (Lucey, 2008a). Against this research and the claims made by the National Research Foundation it may be stated that lean manufacturing results will impact positively on an economy’s growth. AB Company will be evaluated in terms of the readiness and future sustainability of its lean transformation for the purposes of this study. It is anticipated that the results of this study will contribute toward reducing the risk of failure associated with a major lean transformation in the business.

- Description: Robotic simulators for use in Evolutionary Robotics (ER) have certain challenges associated with the complexity of their construction and the accuracy of predictions made by these simulators. Such robotic simulators are often based on physics models, which have been shown to produce accurate results. However, the construction of physics-based simulators can be complex and time-consuming. Alternative simulation schemes construct robotic simulators from empirically-collected data. Such empirical simulators, however, also have associated challenges, such as that some of these simulators do not generalize well on the data from which they are constructed, as these models employ simple interpolation on said data. As a result of the identified challenges in existing robotic simulators for use in ER, this project investigates the potential use of Artificial Neural Networks, henceforth simply referred to as Neural Networks (NNs), as alternative robotic simulators. In contrast to physics models, NN-based simulators can be constructed without needing an explicit mathematical model of the system being modeled, which can simplify simulator development. Furthermore, the generalization capabilities of NNs suggest that NNs could generalize well on data from which these simulators are constructed. These generalization abilities of NNs, along with NNs’ noise tolerance, suggest that NNs could be well-suited to application in robotics simulation. Investigating whether NNs can be effectively used as robotic simulators in ER is thus the endeavour of this work. Since not much research has been done in employing NNs as robotic simulators, many aspects of the experimental framework on which this dissertation reports needed to be carefully decided upon. Two robot morphologies were selected on which the NN simulators created in this work were based, namely a differentially steered robot and an inverted pendulum robot. Motion tracking and robotic sensor logging were used to acquire data from which the NN simulators were constructed. Furthermore, custom code was written for almost all aspects of the study, namely data acquisition for NN training, the actual NN training process, the evolution of robotic controllers using the created NN simulators, as well as the onboard robotic implementations of evolved controllers. Experimental tests performed in order to determine ideal topologies for each of the NN simulators developed in this study indicated that different NN topologies can lead to large differences in training accuracy. After performing these tests, the training accuracy of the created simulators was analyzed. This analysis showed that the NN simulators generally trained well and could generalize well on data not presented during simulator construction. In order to validate the feasibility of the created NN simulators in the ER process, these simulators were subsequently used to evolve controllers in simulation, similar to controllers developed in related studies. Encouraging results were obtained, with the newly-evolved controllers allowing real-world experimental robots to exhibit obstacle avoidance and light-approaching behaviour with a reasonable degree of success. The created NN simulators furthermore allowed for the successful evolution of a complex inverted pendulum stabilization controller in simulation. It was thus clearly established that NN-based robotic simulators can be successfully employed as alternative simulation schemes in the ER process.

- Description: The engineering consulting industry in South Africa witnessed an overwhelming growth before the 2010 Fifa World Cup. The country had a lot of infrastructural development that needed the services of consulting engineers. A lot of people saw the challenge as a business opportunity and started their own consulting engineering companies. The demand for consulting engineering services was high before the 2010 Fifa World Cup; this changed after the completion of projects that were due for the world cup and some had to close or retrench staff due to scarcity of projects. The completion of 2010 Fifa World Cup projects is not the only challenge faced by the engineering consulting sector; government policies such tendering and procurement procedures that do not acknowledge performance, lack of funding etc. It is therefore important that companies look for better ways of gaining competitiveness in order to get more projects. These companies must not only rely on government projects but do marketing on the private sector as well. The purpose of the research is to assess and develop a marketing strategy for Company X Consulting engineers. A literature study on most successful marketing strategies employed by other service oriented companies was conducted. The literature study also comprised of the perception of marketing amongst consulting engineering companies. From the literature study mentioned above; questionnaires were drawn towards the development of a marketing strategy for Company X consulting engineers. The findings of the questionnaires were analysed and recommendation were made for the development of a marketing strategy for Company X.

- Description: As limited prey availability and persecution by humans in response to livestock predation are key conservation concerns for the Cape leopard (Martins & Martins 2006), the present study aimed to provide more information regarding their feeding habits. The first objective was to determine whether the Cape leopard was subject to a change in their prey base and how they responded to the change. This was established by comparison of their current diet in the Cederberg and Gamka Mountains, determined by using scat analysis techniques, with a previous dietary assessment (Norton et al. 1986). The second aim was to provide a preliminary assessment of the prey preference of the Cape leopard and examine the utility of camera trap surveys to determine leopard prey preference. Leopard diet in the Cederberg and Gamka Mountains consisted largely of small- (1-10 kg) and medium-sized (10-40 kg) mammals; rock hyraxes (Procavia capensis) and klipspringers (Oreotragus oreotragus) were key prey items. In terms of regional variation in leopard diet, there was a significant difference in the average weight of prey utilized in the Cederberg and Gamka Mountains. Despite the importance of prey availability of suitable size, their flexibility in terms of prey size utilization reflected their ability to switch to smaller prey to fulfil their dietary requirements, when prey is limited. The study suggested a dietary shift, with significant variation in prey species utilization in both regions. The shift did not appear to be in response to prey scarcity, but rather a reduction in key prey species, particularly the rock hyrax. The shift involved an increase in the number of species utilized, and only a very small increase in livestock predation in both areas. There was however no significant variation in prey size category utilization. This demonstrated their dietary flexibility, as well as the importance of suitable prey sizes rather than the presence of specific prey species to fulfil their dietary requirements. The camera trap survey revealed a strong correlation between the number of camera trap days and the number of photographs taken of identifiable species. Variation of this correlation between different habitats supported the notion that individual images are a better unit to determine sampling efficiency than trap days. The camera trap survey also showed that small rodent availability was underestimated by camera trap surveillance, which resulted in poor prey preference estimation. It was therefore suggested that camera trap surveys be restricted to the surveillance of larger prey species (> 1 kg). By excluding small rodents from the analysis, prey preference could be estimated for other species and prey size categories. Small- and medium-sized mammals were significantly preferred, whereas large mammals were significantly avoided by the Cape leopard.

Leopard diet in the Cederberg and Gamka Mountains consisted largely of small- (1-10 kg) and medium-sized (10-40 kg) mammals; rock hyraxes (Procavia capensis) and klipspringers (Oreotragus oreotragus) were key prey items. In terms of regional variation in leopard diet, there was a significant difference in the average weight of prey utilized in the Cederberg and Gamka Mountains. Despite the importance of prey availability of suitable size, their flexibility in terms of prey size utilization reflected their ability to switch to smaller prey to fulfil their dietary requirements, when prey is limited. The study suggested a dietary shift, with significant variation in prey species utilization in both regions. The shift did not appear to be in response to prey scarcity, but rather a reduction in key prey species, particularly the rock hyrax. The shift involved an increase in the number of species utilized, and only a very small increase in livestock predation in both areas. There was however no significant variation in prey size category utilization. This demonstrated their dietary flexibility, as well as the importance of suitable prey sizes rather than the presence of specific prey species to fulfil their dietary requirements. The camera trap survey revealed a strong correlation between the number of camera trap days and the number of photographs taken of identifiable species. Variation of this correlation between different habitats supported the notion that individual images are a better unit to determine sampling efficiency than trap days. The camera trap survey also showed that small rodent availability was underestimated by camera trap surveillance, which resulted in poor prey preference estimation. It was therefore suggested that camera trap surveys be restricted to the surveillance of larger prey species (> 1 kg). By excluding small rodents from the analysis, prey preference could be estimated for other species and prey size categories. Small- and medium-sized mammals were significantly preferred, whereas large mammals were significantly avoided by the Cape leopard.

- Description: Wildlife ranching is recognized as one of the important agricultural industries in South Africa, with hunting being the primary segment of the game industry. Hunting is an essential part of wildlife management and it contributes significantly to the conservation of biodiversity and to the economy. Despite this, the social acceptability of hunting is often questioned and negative attitudes towards hunting within the larger society may become a potential threat to the hunting industry. This may jeopardize the effective management of game and have a negative impact on conservation and the economy. This study is an empirical investigation of the attitudes of the economically active public in Port Elizabeth towards hunting. The objectives of this study are to investigate the nature and extent of the public's attitudes towards hunting, as well as to identify factors influencing the public's attitudes towards hunting. The study commenced with the establishment of a theoretical framework, based on a literature study on the psychology of human perceptions and attitudes towards hunting. The theoretical framework was then used to develop the empirical component of the study. A survey was conducted amongst a statistically representative sample of the economically active public in Port Elizabeth during 2009. The data was collected by means of personal interviews and self-administered questionnaires were used as the survey instrument. The study found that the economically active public in Port Elizabeth generally holds favourable attitudes towards hunting, with only a small proportion of the population wanting to ban hunting. The belief that hunting endangers wildlife was the most prominent reason for opposing hunting. Negative attitudes towards hunting were largely based on incorrect beliefs regarding hunting. The extent of a person's knowledge of hunting and exposure to hunting, as well as a person's social ties had a significant influence on their attitudes towards hunting.

- Description: The business environment and the economy of the society today are continuously witnessing the impact of globalisation. Telecommunication advancement and transportation has greatly made the impact of globalisation to be felt. Globalisation though argued to have its merits and its demerits have resulted in fierce competition amongst businesses. The banking industry is not isolated from these competitions. Any business wishing to survive and stay profitable in the recent world must be able to compete in the global economy. Hence, for any bank to sustain itself and remain profitable it must be able to withstand the competition in the environment it operates. To be able to compete in the banking industry means delivering better services to customers than competitors. This study presents how the South African banks can satisfy their customers and remain profitable in the face of competition. The South African banking industry consists of local and foreign banks and these banks compete for customers in the environment in which they are located. Increase in different branches by different banks has made the competition even fierce. In other to suggest recommendations for the South African banks to satisfy their customers and become profitable, the researcher identified some problem areas that need to be improved upon. These include customer loyalty, relationship banking and electronic banking. These variables were researched to understand how they affect the banks and the customers and where tested using both a qualitative and a quantitative analysis to ascertain if the customers were satisfied with the banks‟ approach of managing these variables. The results indicated that the customers were satisfied to a lesser extent. Any bank wishing to satisfy its customers and remain profitable in other to compete in the industry needs to satisfy the customer to a large extent. Therefore, recommendations where suggested based on the empirical results to help improve the banking industry‟s ways of attracting and retaining customers. The former will lead to customer satisfaction which again will lead to increased profitability.
