  • Description: This study aims to uncover the synoptic weather circulation pattern which is associated with the occurrence of needle ice, snowfall and the zero-curtain effect. The method of study was done through an intensive ground climate measurement campaign from April 2008 to May 2009 with a temperature logger installed throughout the recording period. Results from data analyses indicate that the complex changes in climate parameters may lead to an equally complex response in terms of spatial soil frost dynamics and its direct and indirect effects on soil sediment displacement and ecosystem dynamics. Field evidence in the study suggests that on Marion Island needle ice developed in temperatures as high as -0.2 ºC in strong winds. This confirms that the wet environment of Marion Island, which is dominated by diurnal soil frost is fundamentally different from seasonal frost and permafrost environments. The scoria material is susceptible to needle ice growth and the compacted soil alters the micro-climatology of the affected area making it more susceptible to the formation of needle ice. Soil moisture for needle ice formation and growth is provided by the misty conditions associated with the advent of the cold front (pre-cyclonic). Furthermore, observations of needle ice on Marion show that needles are mostly clear with no sediment inclusion. This is indicative of needle ice formation that has not been interrupted by a shortage of moisture. The zero-curtain effect on Marion Island can occur either as a response to the thawing of the soil after the seasonal freeze. The synoptic assessment of snowfall on Marion Island indicates that; snowfall is associated with the passage of a cold front linked to a strong meridional system of low pressure just south of the island.

  • Description: When the current South African government came into power two decades ago they inherited a fragmented health care system whose main focus was on the tertiary care level. The strategy of the current government was to re-focus the whole health care system and prioritize primary health care system. That included setting up district health care systems and building primary health care centres in the areas within the communities in order to make health care accessible to everybody. Due to financial difficulties the majority of the people staying in these communities solely depend on these clinics as they cannot afford to buy health care services in the private sector. The study seeks to assess the current medication supply chain to these clinics with a view of coming up with recommendations that, when implemented, will ensure that the supply of medication by the clinics is able to meet the demands of their patients. Lean management is a system that was started in the manufacturing sector and because of its success there it was later adopted by the service industry. Lean is a system that seeks to eliminate all forms of waste and improve the quality of the service rendered to the satisfaction of the customer/patient. Literature review and discussion of lean implementation is discussed extensively. The findings of the study are presented, analyzed and discussed. In these findings it is noted that the system is functioning very well but there are challenges in these clinics that need to be addressed. Recommendations of how lean management can be implemented successfully to optimize the functioning of the current system are discusse The permission received from the Department of Health to conduct this study came with contractual obligations that the researcher promised to honour. One of those requirement stated clearly that the findings of the study should not be published anywhere without the permission of the Department (see addendums A & C). It is under that premise that the researcher wants to bring this to the attention of the relevant university departments, with the hope of ensuring that this contractual obligation is honoured.

  • Description: This is a quantitative study. The primary research objective is to investigate the importance of hospital management’s involvement when implementing lean elements in healthcare. In reality, incidents and quality problems are prime reasons why healthcare leaders are calling for redesign in healthcare delivery and systems. This paper presents a proposal for developing a lean culture in healthcare facilities equipped with managers who will be able to drive the implementation of lean elements from the top down, making use of multidisciplinary teams, including physicians, to deliver value-added services. This study ultimately endeavors to indicate the importance of management, multidisciplinary teams and physician involvement in implementing lean principles in healthcare successfully. “If we keep doing what we’re doing, we’re going to keep getting what we’re getting.” – Stephen Covey. The reasons why lean management is a particularly important strategy in healthcare currently, includes the following: •The need to reduce waste in healthcare cost; •The need to improve quality and on-time processes; •Fast-paced technological changes; •Ever-increasing patient expectations; and •The need to standardise processes and systems to get the high-quality results anticipated (Chalice, 2010).

  • Description: The need to achieve developmental local government in South Africa has necessitated that the municipalities and other government departments pay more attention to the poor so that they can be helped to live more fruitful lives and become the instruments for the growth of local economy. This study seeks to assess the impact of Local Economic Development (LED) initiatives in Mbhashe Local Municipality with special focus on the Maize Production Project (MPP). The areas of Mbhashe municipality that were included in the study include Ndakeni village near Dutywa, Tswele-litye near Willowvale and Madwaleni near Elliotdale. The study followed both the qualitative and quantitative research approaches and the respondents were made up of a sample of MPP beneficiaries from the three areas mentioned above, Community Leaders and the Officials. The objectives of the study were to identify MPP objectives, to identify challenges in the implementation of the MPP, to assess the availability of remedial measures and lastly, to assess whether the community has benefited from the maize production project or not. Among others, the objectives of the MPP were to maximise maize production, to make profit, to create employment opportunities for the unemployed. Only 13 percent of the surveyed beneficiaries believe that their expectations of this initiative were fully met. The majority (two thirds) believe that their expectations were partly met, whilst one in five (20 percent) believe that their expectations were not met at all. The MPP implementation challenges included delays caused by the municipal procurement processes, unfavourable climate conditions, poor service delivery by the appointed service providers who provide tractors, shortage of funds and late start for ploughing. Even though the remedial measures seem to be in place, the implementation and the communication of the strategies remains a big challenge. Furthermore a proportion of the respondents were unhappy with the public participation process that preceded the implementation of the project.According to the findings, two thirds (67 percent) of the surveyed farmers believe that their communities have benefited from the MPP, although one third (33 percent) disagreed. The challenges of an insufficient budget, procurement delays and late commencement of ploughing need to be addressed if the maize production initiative is to yield the desired results.

  • Description: The purpose of the study was to assess the implementation of peer academic support programmes which are Language and Writing Advancement and Supplemental Instruction programmes in one University in South Africa. The study adopted a qualitative approach that used face-to-face interviews, focus group interviews and document analysis to collect data. Purposive sampling was used to select those who participated in the study. The participants were two coordinators of the programmes, ten facilitators working in the programmes for in-depth interviews and ten students who have been receiving services from the programmes for two focus group discussions. The study revealed that there was a general trend whereby peer facilitators of the programmes were recruited and trained. However, it was found that some facilitators abandoned the position immediately after the training which made it difficult for coordinators and Human Resource Staff (HR) to start the process of recruitment and retraining. In this regard, Teaching and Learning Centre, (TLC) and HR simply appointed other untrained facilitators to replace those who had deserted the positions. Also, some facilitators were unable to attend some of the regular trainings because of clashes with their classes. All these have a negative impact on the implementation of the programmes. The results also reveal that some of the facilitators were frustrated with students’ poor attendance in the sessions, and even those who attended their sessions, did not participate much in the discussions. It was found that most lecturers and students did not know the differences between supplemental instruction (SI) and tutorials. Neither did lecturers encourage their students to seek help from the TLC services. Reviewing of assignments from different disciplines by TLC facilitators was another burning issue that came up. Some facilitators reviewed assignments from different disciplines, because the disciplines were not represented and this is because they want to claim for more hours, which affects the quality of the programmes. The findings also show that some students did not like to take their assignment to the TLC for review because facilitators make unnecessary and harsh comments. On the contrary, some students acknowledged that they were fine with the way facilitators review assignments because it involves one-on-one consultation, and they always pass the assignments reviewed by PASS facilitators. The study also revealed that the coordinators monitored and evaluated facilitators through observation and the checking of attendance registers. Coordinators ware also monitored by senior colleagues of the department such as the manager of the TLC. Furthermore TLC has instituted a mentorship programme whereby senior facilitators mentor newly recruited facilitators. However not every facilitator had a mentor. The study also exposed the fact that the TLC venue was usually closed during examination periods to allow facilitators to prepare for their examinations. The findings show that some departments were not represented by facilitators and to remedy this situation, it is recommended that all departments be represented and lecturers encourage the students to get help from TLC. Most facilitators were undergraduate students, but they needed to be replaced by post graduates who did not have course work that will clash with PASS activities. The strategies used by facilitators were fairly good but more should be done to encourage students to participate in sessions. Finally, the monitoring and support mechanisms put in place were very functional but the TLC should make sure every facilitator is being monitored especially concerning the review of assignments. The significance of the findings of this study cannot be overemphasised. The strengths and challenges regarding the implementation of these programmes at this particular university have been revealed. Through the recommendations, it is hoped that the institution and the TLC would effect some changes in the implementation of these peer academic support programmes in order to better serve the students so as to achieve satisfactory throughput and retention rates.

  • Description: The marine fishery in Kenya is predominantly small-scale and artisanal with about 11,000 fishers intensely fishing near shore coastal reefs using minimally selective fishing gears. A large majority (88%) of fishers use outdated equipment such as basket traps, beach seines, hand lines (hook and lines), fence traps, gillnets, spearguns and cast nets. Handmade canoes propelled by paddles (kasia) or sail power are used to access offshore waters, while only a few fishers have motorized boats. Although fishers along this coast know and express the potential of offshore fishing, most of them are disempowered and unable to access any of the largely untapped offshore pelagic resources. Using a unique dataset from four distinct coastal areas: Funzi-Shirazi bay area, Diani-Chale area, Mombasa-Kilifi north coast area and the Malindi-Ungwana bay area, containing species level length frequency catch data from the multi-gear and multi-species fishery, abundance of specific species, gear use comparisons in various regions, catch per unit effort and total catch estimate over a nine year period (2001 – 2009) were evaluated. Despite high diversity in the fishery, five species (Lethrinus lentjan, Siganus sutor, Leptoscarus vaigiensis, Lethrinus harak and Parupeneus macronemus) represented over 75% of the catch. A total of 11 legitimate gears were observed in this coastal artisanal fishery with basket traps (42%) being the most popular. Fishers along the Mombasa-Kilifi area predominatly used beach seines while those in Diani-Chale, Malindi-Ungwana bay and Funzi-shirazi bay predominaltly used spearguns, gillnets and basket traps, respectively. Apart from gillnets, a general declining trend for most of the gear types was observed since 2004. Beach seines recorded the lowest (20.9±0.2 cm) mean length while gillnets recorded the highest (34.2±0.3 cm). The highest catch (~26,000 metric tons) came in 2001 and the lowest (~15,000 metric tons) in 2005. The highest number of fishers was observed in 2008 while 2009 recorded the highest (4.8±2.3) mean number of hours per outing. The mean annual CPUE per region ranged from (1.5 kg.fisher-1.hr-1) in Diani-Chale to (1.0 kg.fisher-1.hr-1) in Malindi-Ungwana bay. Making use of questionnaire data, the attitudes towards offshore fishing strategies, FADs in particular, were evaluated. Some communities (about 25% in every location) were not even aware of FAD fisheries. With the imminent introduction of a FAD fishery in Kenya, it was concluded that, for this fishery to realize its full potential, training on FAD fishing techniques has to be done. Finally, effective management is necessary if small-scale fisheries are to continue providing food security for many poor coastal communities. Gear-based management in Kenya, although under represented and under studied, has the potential to be adaptive, address multiple objectives, and be crafted to the socio-economic setting. Management effectiveness in near shore fisheries has generally been evaluated at the scale of the fish community. However, community level indicators can mask species-specific declines that provide significant portions of the fisheries yields and income. This thesis seeks to identify ways in which the Kenyan artisanal fishery can be sustained and managed from within coastal communities, giving them the resources and education to effectively improve their lives. The introduction of a offshore FAD fishery and hence access to offshore pelagic species provides an opportunity to not only alleviate pressure on coastal resources but also to empower coastal communities and contribute to the growth of Kenya’s national economy as a whole.

  • Description: Mnquma Local Municipality is located in the South Eastern part of the Eastern Cape Province. This category B municipality falls under the jurisdiction of the Amathole District Municipality (ADM) and comprises of an amalgamation of the former Butterworth, Ngqamakhwe and Centane TRC’s, Mnquma Municipality shares borders with three other local municipalities i.e. Mbhashe, Intsika Yethu and Great Kei Municipalities. In previous years this municipality was surrounded by violence, maladministration and mismanagement of funds. In 2009, Mnquma municipality received a disclaimer audit opinion. The bases for disclaimer are: - Consumer debtors who were disclosed at R13, 4 million on the face of the statement of financial positions and to the annual financial statements; and this amount did not agree with debtor’s age analysis; - Auditor-General was unable to confirm the exact amount of debtors removed from the accounting system; - Limitations placed on the scope of work and municipal records not permitting the application of alternative audit procedures; - Trade Creditors not supported by adequate documentation and supplier reconciliations did not have adequate alternative system of ensuring that all goods and services received prior to year-end, not paid but were accrued; and number of items that were recorded incorrectly. “The municipality adopted the PMS framework by March 2008. It was implemented and Councillors played a pivotal role in the implementation, monitoring and evaluation of theIDP. Cluster meetings set and received performance reports on quarterly basis. Directorates produced monthly performance reports and submitted them to the Executive management and the Executive Mayor respectively. The PMS was cascaded down to lower levels. Managers reporting to Directors had signed Accountability Agreements, while employees below signed Performance promises. It should be stated that there were some challenges on the implementation process. The Framework was implemented for the first time and institution was in a learning curve”. (N. Pakade: 2009). The municipal manager agreed that the institution was in a learning curve even though he commended the good work of councillors, it is not all councillors who know exactly what they are supposed to be doing in monitoring the municipal performance management systems. This has been proved by areas which still do not have electricity, roads and some no running clean water. There were some improvements in 2010 Financial Statements because the municipality received an unqualified audit opinion, but the in- fighting amongst councilors still existing that affect municipal performance in regard to provide local communities with basic needs. The irregular expenditure continued to be incurred where two different security companies were appointed by Executive Mayor and Municipal Speaker to prevent each other in entering the municipal premises because of disagreements about the reappointment of the municipal manager. Mnquma municipality does not have an Executive Mayor due to councilors who fired the mayor. The Mnquma councilors’ in fighting affects local communities in a negative way that contributes to municipal bad performance.

  • Description: This study responds to the need to understand the shifts in the national monitoring and evaluation policy context from output and compliance focus to outcomes and performance focus. The study also responds to need to understand how national policies are interpreted and implemented in the province through the Office of the Premier. The purpose of the study is to assess the monitoring and evaluation function in the Eastern Cape Office of the Premier. The following research questions will guide the study: a. What is the context, rationale, purpose and claims of the National M&E Policy? b. How does the Eastern Cape Office of the Premier implement the monitoring & evaluation function? c. How does the implementation of M&E by Office of the Premier resonate with intention of the National M&E policy & what are the gaps. In this study, both qualitative and quantitative approaches were used. The use of interviews and questionnaires demonstrates the mix method approach. This approach was preferred since one part of the research analyses policy documents and the other one assesses implementation. The key findings of the research were: Although the context, rationale, purpose and claims of the National and Provincial M&E Policies are clearly articulated, there is no national legislation that gives the Office of the Premier power to enforce the implementation of the M&E policies. Both national and provincial M&E policies are not sensitive to the context of implementation. There is poor enabling environment in the Office of the Premier to implement M&E. There is a gap between planning and M&E functions in the Province the Premier’s Office, Provincial Treasury and Department of Local Government have not succeeded in coordination and the definition of roles and responsibilities for rolling out a Province wide M&E system. The M&E Policies do not address the problem of duplicate reporting in the Province. The M&E Provincial Framework has several limitations that will affect implementation. The National M&E policies are silent on the monitoring role of the legislative branch of government. There is no alignment between the development and monitoring of Service Delivery Improvement Plans with the rest of the implementation of M&E policies. Poor intergovernmental relations in the province make it difficult to fully implement M&E policies. . Programme Managers focus narrowly on day to day management functions with little or no focus on monitoring and evaluation. There was very poor usage for M&E evidence by the for decision making.

  • Description: This dissertation is an assessment of the nature and implementation of marketing strategies of selected Eastern Cape non-government organisations. Poverty alleviation and service delivery remain the major focus of the South African government, after nineteen years of democracy (post-apartheid era). One of the civil societies that is key in working with the government in alleviating poverty and looking after the interests of the poor and marginalised individuals within the society is non-government organisations (NGOs). NGOs are organisations that are voluntary, independent, not-for-profit, and not self-serving in aims and related values. In August 1995, NGOs moved very quickly to establish the South African NGO Coalition (Sangoco). This was as a result of the Non-Profit Organisations Act 1997. Government reorganised the political environment for NGOs. They were provided with access to the fourth chamber of the National Economic Labour and Development Council, - the country's premier corporatist-style consensus-building agency, - on condition that such representation occurs through a single body. Sangoco now serves as a representative umbrella body for approximately 6,000 affiliated NGOs. Sangoco's primary role is that of advancing the interests of the poor. It is also concerned with developing an enabling environment for the NGO sector and providing an arena for mutual monitoring. Even though the Non-Profit Organisations Act opened the doors for NGOs to raise funds freely and also obtain allowances from the government, the bureaucratisation and commercialisation of NGOs made it almost impossible to access these funds, hence, most NGOs today are closing down. A literature review was conducted to determine what theory reveals about strategic marketing for profit organisations. Furthermore, how the marketing principles that are used in businesses can be implemented to ensure sustainability of non-profit organisations. The empirical study was conducted through questionnaires and interviews with the management of the NGOs. In Chapter 4 of this study findings are presented and in Chapter 5 recommendations are made. Further studies can be conducted to determine some of the areas that the NGOs can improve on, in order to run an effective and efficient non-profit organization.

  • Description: The Eastern Cape Department of Education consumes a huge chunk of the Eastern Cape provincial budget. Any transgression of the laws that govern how the public purse should be managed - whether overspending, under spending, irregular or wasteful expenditure - has far reaching consequences in terms of service delivery. The Eastern Cape is one of the poorest and most rural provinces in the country and by implication has huge service delivery backlogs .This has been confirmed by various stakeholders and role-players such as Chapter Nine institutions and non-governmental organisations. An observation by the Auditor-General and both the portfolio committees on Public Accounts and Education over the years is the lack of proper controls, especially in financial management. This study presents a case study of the Eastern Cape Department of Education in the financial years 2007-2012 to assess the Public Finance Management Act, Act 1 of 1999 (PFMA). The main objective of this study is to assist the department by putting forward lasting scientific recommendations and solutions that could be integrated into the plans of this department.

  • Description: The intention of the study was to assess the supply chain management policy at the King William’s Town District Municipality. It became apparent from the Literature review that any municipality to play a meaningful role in ensuring that South Africa achieves the goal of becoming a developmental state, capable of confronting service delivery challenges, there needs to be a proper implementation of the supply management system policy. The study was also aimed at identifying the factors that support or hinder the implementation of the supply chain management within the King William’s Town District Municipality. In order to achieve this objective, interviews and self-administered questionnaires were conducted with various respondents in the municipality. The respondents insured the councillors from the five political parties comprising the municipality, municipal manager and section 57 managers, supply chain practitioners. It would therefore be critical important for the management of the King William’s Town District municipality to take into account the results of this study and its recommendations so as to ensure that there is a proper implementation of the supply chain management system within the municipality.

  • Description: In order to meet the different public needs and requirements of contemporary urban society, a better understanding of public perceptions, appreciation and knowledge of the assorted values derived from urban trees is beneficial for improved urban greening. Thus, this study carried out an assessment of urban residents’ knowledge and appreciation of the benefits of trees and the role they play in enhancing the quality of life in urban systems. The study primarily focused on the intangible benefits (also referred to as cultural and regulating services) of urban trees, because most research to date in South Africa on trees and the benefits derived from them is biased towards the provisioning services of trees in rural areas. The significance and contribution of the intangible benefits of trees in urban systems is often underestimated and not seriously taken into account by urban planners, policy makers and other key decision makers. The study was conducted in three different residential settlement types (formal townships, RDP settlements and informal settlements) in two towns in the Limpopo Province in South Africa, namely Bela-Bela and Tzaneen. Findings revealed that the intangible benefits of trees are seen to play a significant role in improving both residents’ quality of life and the environmental conditions in cities, including the preservation of biodiversity. Findings also showed that urban residents had strong spiritual connections with trees and placed considerable cultural and historical importance on specific tree species and individual trees. Urban residents in both towns had moderate knowledge of the intangible benefits of trees based on the knowledge score that was created for the purposes of this study. Fifty seven percent of the residents had ‘reasonable’ knowledge of some of the intangible benefits of trees, while 43% had low levels of knowledge. That said, the majority of residents demonstrated high appreciation (98%) of the intangible benefits of trees (especially social and cultural values), with few residents not recognising these, suggesting that knowledge does not necessarily lead to appreciation. Age and level of education were found to influence knowledge of the intangible benefits of trees. A large proportion (86%) of residents who possessed tertiary level qualifications had more knowledge of the intangible benefits of trees as compared to residents with no formal education. Findings also revealed that younger respondents (60%) had more knowledge of the intangible benefits of trees. Factors that influenced appreciation of the intangible benefits of trees included links to crime, peoples’ value systems (their pro-environmental and altruistic values) and residential settlement type. Sixty five percent of residents in both towns felt that urban street trees and trees in public spaces attract criminals and promote crime, while 67% of RDP and 96% of informal township residents did not use or appreciate the social and recreational benefits of trees mainly because of the absence or long distances to public parks. A Willingness To Pay (WTP) survey revealed that a high proportion of residents in Bela-Bela (86%) were WTP a small annual fee in order to sustain greening initiatives in their communities compared to the residents in Tzaneen (53%). In terms of the planting and retention of trees, it was found that 300 households in both study towns had planted and retained a total of 1 615 trees in spite of the various factors that negatively influenced planting and retention of trees such as residency time and tenure security. The majority (66%) of informal township residents said tenure security was an important factor to consider when making tree planting decisions, while this was not an issue for formal township and RDP residents. Policy implications and recommendations are presented to help municipalities and urban planners improve and develop effective policies and programmes that will enable implementation of sustainable urban greening programmes

  • Description: Municipalities play an important role in accelerating service delivery to all communities. This study is an assessment of skills development programmes for selected employees at the Amathole District Municipality (ADM). The ADM is known as a predominantly rural district. The study revealed that the municipality is faced with a lack of proper skills to accelerate service delivery. This has resulted in the institution neglecting to invest in the development of those competencies needed to function in a constantly changing educational, training and development environment. The success of any organisation depends on its human resources, who are the most important asset. Therefore effective and efficient human resources management and training and development management play a critical role in the well-being of employees. Human resources training and development policies, practices and activities guide the institution with implementation of services and should take on a more strategic role to achieve their objectives. The researcher employed the quantitative research methodology for purposes of the empirical survey and also reviewed official documents and reports. A suitably constructed questionnaire was developed and distributed to the selected sample group from the ADM. The researcher also consulted legislation, official documents, articles, journals, policy documents, reports and books in an effort to obtain as much relevant information as possible. Based on the information gathered from the respondents and literature review the researcher proposes certain recommendations in the final chapter of the treatise.

  • Description: The South African sheep industry has experienced an increase in the price of meat and wool over the past several years. This has led to an interest in intensification of sheep production off planted pastures. Due to this phenomenon an economic viability study was done on the intensification of sheep production on cultivated pastures under irrigation. When intensifying sheep production, certain management practices need to be incorporated in order to enhance the output obtained per hectare and to overcome the higher input cost of production. Management practices that could be included are creep feeding, accelerated breeding and feedlotting of lambs after weaning. In order to determine the economic viability of such a system, certain production parameters need to be obtained for producing sheep intensively from cultivated pastures. Three studies were conducted to obtain the required production parameters; these were then followed by an economic evaluation incorporating the parameters obtained from the studies. All the studies were conducted at Kromme Rhee and Langgewens, two research farms of the Department of Agriculture in the Western Cape.

  • Description: South Africa relies heavily on fossil fuels, particularly coal, to generate electricity and it is a well known fact that the use of fossil fuels contributes to climate change, as it produces greenhouse gases (GHGs). In fact, internationally South Africa is the 17th highest emitter of GHGs (Congressional Research Service (CRS), 2008). Coupled with the environmental consequences of fossil fuel use, South Africa has a further responsibility of addressing the inherited backlog of electricity provision to the rural, and previously disadvantaged communities. In an attempt to address these two problems, the government issued the White Paper on Renewable Energy. In this paper, renewable energy alternatives are proposed to replace a portion of traditional electricity generating methods. Concentrator photovoltaic (CPV) energy generation is one such renewable option available to government. CPV uses optic elements (such as lenses) to concentrate sunlight onto solar cells. Owing to the light being concentrated, the cells in CPV use less semiconductor material, which makes them more efficient in comparison to conventional photovoltaic (PV) cells. CPV is a technology that operates well in regions with high solar radiation. As such, South Africa is particularly well suited for this technology, with average solar radiation levels ranging from 4.5 to 6.5 05 ℎ/. CPV is also well suited for off-grid application, which addresses electricity demand in remote rural areas. This study is an economic project analysis of the installation, operation, maintenance, and decommissioning of CPV technology in a rural area in the Eastern Cape, South Africa. The study area chosen for this purpose is the Tyefu settlement in the Eastern Cape. Tyefu was deemed ideal for this type of analysis due to four characteristics. Firstly, Tyefu is a remote rural settlement at the end of the national grid. Secondly, the community is very poor and previously disadvantaged. Thirdly, many households are without Eskom generated electricity. Lastly, the study area is located in an area with ideal irradiance levels for CPV. Two methods of economic project analysis are applied to this case study, namely a costbenefit analysis (CBA) and a cost-effectiveness analysis (CEA). Additionally, two types of CBA are performed, namely a private CBA and a social CBA. The private CBA evaluates the Tyefu electrification project from a private investor's perspective and the social CBA evaluates the project from society's point of view. The CEAs carried out compare the costeffectiveness of the traditional PV technology to that of CPV in terms of private and social costs. The private costs and benefits of the CPV project were identified and valued in terms of market prices. Then, this cost benefit profile was used to calculate net benefits which in turn were discounted to present values using a private discount rate of 6.42 percent. Three decision making criteria were generated, namely the net present value (NPV), the internal rate of return (IRR) and the benefit cost ratio (BCR). Sensitivity analysis was carried out by varying the private discount rate and the bidding price. The social costs and benefits of the CPV project were identified and valued in terms of shadow prices. This cost benefit profile was used to calculate net benefits. The net benefits were discounted to present values using a composite social discount rate equal to 5.97 percent. The same decision making criteria used in the private CBA were used in the social CBA and a sensitivity analysis was completed by varying the social discount rate. In terms of the private CEA, the costs were identified and valued in terms of market prices. All costs were brought to present values using the private discount rate of 6.42 percent. In terms of the social CEA, the costs were identified and valued in terms of shadow prices. All costs were brought to present values using the social discount rate of 5.97 percent. The cost-effectiveness (CE) ratios calculated have identical denominators since the annual output for both technologies are identical - both CPV and PV systems deliver 30 300 kWh per annum. This output is based on the demand of the given case study. The private CBA showed unfavourable results. The private CBA has a NPV of R2 046 629.01, the IRR is undefined (this is due to no sign change being present in the cost benefit profile), and has a BCR of 0.365. However, the social CBA yielded positive results, with a NPV of R125 616.64, an IRR of 8 percent (which exceeds the social discount rate of 5.97 percent), and a BCR of 1.045. The CEA showed that the CPV is more cost-effective than the traditional PV both in terms of private and social costs. The private CE ratio of CPV is R4.23/kWh compared to PV's CE ratio of R4.39/kWh. Similarly, the social CE ratio of CPV is R3.51/kWh compared to PV's CE ratio of R3.69/kWh. CPV rollout appears to be socially efficient on a small scale according to the social CBA. Consequently, the CPV project is not seen as desirable in terms of the private CBA as the benefit (income received per kWh) in the private analysis is too small to outweigh the costs of implementing and running a CPV plant in Tyefu. On the other hand, a redeeming factor is that CPV may be feasible privately, for large scale applications. A major reason for the CPV project not being appealing to private investors is that the maximum bidding price of R2.85/kWh (as at August 2011) is not high enough for private investors to undertake the CPV project. The sensitivity analysis of the bidding price showed that the bidding price of R2.85/kWh needs to be increased in the range of 250 percent (R7.13/kWh) and 300 percent (R8.55/kWh) for a great enough incentive to exist for private investors. It is thus recommended that policymakers take this into consideration when formulating policy. In terms of the social CBA, it is recommended that government undertake CPV projects of this kind, as it will be a socially desirable allocation of resources. If government were to pursue these types of projects, it is recommended that CPV be implemented as it is more cost effective than PV.

  • Description: The identification of financial stress, and an understanding of financial contagion on a global scale, is of critical importance to a South African economy that is becoming increasingly integrated into the global economy. The last decade has been characterised by periods of high economic growth, but also periods of significant financial instability culminating in global economic crises. This study examines the extent to which the South African financial system is exposed to distress abroad by identifying and measuring the co-movement of financial stress originating from within and outside South Africa. The study can be separated into two sections: the identification of financial stress and the measurement of financial contagion. Using monthly data for the period 2000 to 2012, three indices were constructed for the emerging markets, advanced economies and South Africa using varianceequal weighting. The indices were tested for contagion using the Johansen and Jesulius (1990) multivariate cointegration approach supplemented with basic OLS architecture and Impulse Response analysis. The results indicate the three constructed indices were highly accurate at identifying the intensity and timing of financial stress over the three regions respectively. It was found that the South African financial sector is highly susceptible to financial stress originating from advanced economies. The results obtained for financial stress emanating from emerging markets were not as conclusive and found to be insignificant. Overall, it is clear that the methods employed to identify financial stress are highly accurate and that South Africa is highly susceptible to financial stress originating from abroad. It is clear that advanced economies have a greater ability to affect financial stress in South Africa via contagion. It must be noted that this does not conclude that South Africa is not affected by emerging market crises, but that these crises tend to affect South Africa through advanced economy channels as defined within this thesis.

  • Description: This study examines the patterns in the housing investments in South Africa in an attempt to understand if the possibility of the Tobin Q can be used to interpret the patterns and trends in the South African residential investments. The study, in its quest to explore and expose this intermporal relationship, it makes use of the South African annual time series data from 1960- 2010. The data was computed in different economic and econometric analysis software for better and reliable output, depending on the different level econometric technique that is required and need to be captured by the study. The dynamic investment equation is estimated using general- to- specific ARDL approach to magnify this connection and trends. The study established that combined asset prices and the levels of residential investment affect the long run investment performance rather than the Tobin Q. In the short run the lagged values of the Q, Business investment and residential investments seemed to be influential driving forces of private investment in South Africa. Even if the capital reserves in South Africa seem to be healthy, there is always a dire call for policy to be geared in the direction of the accessibility of credit to guarantee a supplementary conducive investment climate.

  • Description: Aversion is a complex phenomenon that arises over time through performance of cognitively demanding tasks and has been associated with the mechanisms of mental fatigue and compensatory control. However, little is known about this sensation to dissociate from the task at hand and the causation thereof. It is apparent that aversion is a negative state for the operator and could result in decreased performance and productivity. Through identification of factors that contribute to aversion when performing cognitively demanding tasks, recommendations to reduce design deficits may be employed to promote worker wellbeing and further advance performance and productivity. The current study examined possible factors that may influence aversion experienced through execution of cognitive tasks. A subsequent aim of this study was to assess a possible cause of aversion. The cause of aversion was hypothesized to be related to efficiency, namely the perception of efficiency when performing tasks and actual efficiency calculated through performance of tasks in relation to the expenditure of effort. Four investigations were undertaken with a non-repeated design between investigations and a repeated design within investigations. The first investigation was an analysis of the effect that stimulus cycling had on the aversion experienced. This consisted of a proof reading task with two conditions varying in the repetitiveness of the text, therefore, allowing an analysis as to how aversion is altered by the provision of a new stimulus to the participants. Investigation two investigated the effect that task difficulty imposed on aversion experienced. This comprised of two conditions with varied difficulty that were implemented through a driving simulator tracking task with difficulty altered by the width of the driving lane. The effect of performance feedback on the aversion experienced towards a task was the focus of the third investigation. The effect on aversion experienced was assessed through a driving simulator tracking task with a condition providing feedback of performance to participants and a condition with no knowledge of performance. The final experiment evaluated the effect of task alternations on aversion. This experiment was conducted through alternations between a driving simulator tracking task and a choice reaction task. The choice reaction tasks required participants to identify critical and non-critical stimulus. Four conditions were required for this experiment and were made up of two conditions where there was provision of alternation that varied in frequencies between the two tasks (medium alternation condition and fast alternation condition) and two conditions where no alternations were instated (driving simulator task condition and choice reaction task condition). Separations between all testing conditions were three or more days apart with sixty participants distributed between the investigations. Test duration of each condition was 30 minutes. Subjective data was recorded throughout investigations for all conditions in the form of aversion, subjectively perceived efficiency and rate of perceived exertion. Objective data was collected in the form of physiological responses and performance of tasks for the analysis of objective efficiency. For factors influencing aversion analysis, no differences in aversion experienced were found for the task difficulty and performance feedback investigations. Aversion was found to be less for the changes imposed through the task cycles and task alternation investigations. This concludes that aversion is aggravated through monotonous tasks and by a change of the stimulus or the structure of the cognitive tasks provided to operators; aversion can be alleviated. The results for the cause of aversion analysis found no difference in objective efficiency over time, with a subsequent decrease in perceived efficiency associated with the increasing aversion. Inference from these findings suggest that aversion cannot be attributed to objective inefficiency of task performance, however it can further be assumed that perception of actual efficiency is inaccurate. Perception of efficiency however had a large influence on the sensation of aversion. Aversion is seen to be more of a product of time on task, however whether this is mechanism of fatigue or compensatory control is still to be determined.

  • Description: The purpose of this study was to gain insight into observed discrepancies between continuous assessment and final examination average marks in Grade 10 Mathematics in the Oshikoto region of Namibia. The study is framed as a case study and is grounded within the interpretive paradigm. A mixed methods approach was applied, eliciting both quantitative as well as qualitative data. The study took place in two phases. In Phase 1, continuous assessment and Grade 10 final examination average marks for 62 Junior Secondary Schools for the period 2008-2010 were gathered and analyzed. Schools were characterized in terms of the relationship between their continuous assessment and final examination average marks for each of the three years. Phase 2, which was informed by Phase 1, took the form of structured interviews with a sample of three Mathematics teachers and three principals along with a focus-group interview of twelve teachers in order to investigate more deeply the perceptions of teachers and principals toward assessment policy and practice. The study shows that Grade 10 assessment practice in Namibian schools is far from ideal. Many teachers are not fully conversant with the various continuous assessment components as outlined by policy, and teachers are not confident about setting appropriate continuous assessment tasks. There is a strong perception that continuous assessment marks can easily be inflated and those teachers who gave high continuous assessment marks to their learners were generally perceived as being either incompetent or dishonest. While continuous assessment was seen as an important component of teaching and learning, it is evident that teachers and principals would welcome greater clarity, along with standardization and moderation, with respect to continuous assessment practice.
