  • Description: The study focused on the efficacy of the democratic education decentralization policy. The study focused on the efficacy of the democratic education decentralization policy implementation of the four schools of Kadoma District in Zimbabwe. The thesis reviewed literature and discussed the concept of the democratic education decentralization policy implementation and how this has been practiced in Zimbabwe. The theoretical basis of democratic education decentralization policies were outlined and the argument for and against the policy discussed. Thus the dissertation explored the concept of education decentralization policy with specific reference to the notions of democratization and participation in Zimbabwe. Besides the qualitative and the quantitative research methods employed, the study was complemented by the observation on the ground and document analysis. The thesis unearthed that; the democratic education decentralization policy is characterized by some successes and problems during implementation of the policy as indicated by the paucity of the teaching and learning resources. The research findings revealed that, there is prevalence of poor learning outcomes at ‘O’ level in schools; the SDCs/SDAs are underutilized sources of school development because they are not fully empowered by the education system since they had a minimum role in participating towards the implementation of the policy in order to acquire the teaching and learning resources at the schools in Kadoma District. The above findings long-established the view held by critical theorists of the Participatory Governance Model that there is a complementary relationship between the participation of the SDC/SDA in acquiring the teaching as well as the learning resources and the academic performance of learners.

  • Description: Governments strive to improve the efficiency of service delivery with the intention of achieving societal goals. Thus, in order to ensure the quality of public services and goods provided to the people, central governments need to follow a decentralised governance approach. The decentralisation theorem states that, if the consumption of public goods and services over different geographical regions of the total population and the cost of providing these public goods and services in each region are the same for both the central and the sub-national government, the provision of public goods and services will be more efficient if they are provided by the sub-national government to their respective jurisdictions. This dissertation’s main aim is to investigate the extent to which the Eastern Cape Provincial Government (ECPG) is efficient in the provision of social services to the people under their jurisdiction. The efficiency scores obtained using the Data Envelopment Analysis Computer Program (DEAP) 2.1 version proved that the ECPG, education, health, social welfare and the housing departments are inefficient in the provision of social services. In this case, fiscal decentralisation as an appropriate vehicle for service delivery seems not to be working for the Eastern Cape Province, unless there is an improvement in the efficiency levels at which the social services are provided by these departments.

  • Description: Scanning electron microscopy (SEM) investigation carried out on the eggs of Afronurus scotti, A. harrisoni, A. peringueyi, and A. ugandanus, has provided some chorionic details useful for a comparison between these species. In all the species, the egg chorion is decorated with sparse granules and shows two kinds of knob-terminated coiled threads (KCTs). The first kind is represented by small KCTs (5-7 ?m in diameter) densely concentrated at each egg pole; the second kind encompasses large KCTs (60- 80 ?m in length) situated equatorially. The micropyle has an oval to round sperm guide (15-20 ?m long; 12- 18 ?m wide), and a well-defined rim. The polar KCTs expand towards the equatorial KCTs in A. scotti, A. harrisoni, and A. peringueyi, but in A. ugandanus there is a large clear area between polar and equatorial KCTs. A chorionic pattern very close to that of these Afronurus species is shared only by species belonging to the Asiatic genus Cinygmina. In addition, examination of the labrum of the nymphs belonging to both genera, indicates a very similar morphology, in the curved sclerification in the basal region of the labrum, a feature that contrasts with the almost straight shape presented by other heptageniid genera (e.g. Electrogena species). Egg and labrum characteristics are advocated to hypothesise a close phylogenetic relationship between the South-African Afronurus and the Asiatic Cinygmina genera.

  • Description: Urban areas in developing countries will accommodate nearly 90% of the projected world population increase between 1995 and 2030. Despite this, few studies, especially in smaller towns, have been carried out on urban green space areas in the developing world. This paper makes a first step in this regard, reporting on the extent and state of urban green spaces within 10 small towns in the Eastern Cape (South Africa). After measuring the size and state (in terms of woody plant cover) of public green space, we then sought patterns across the 10 towns between green space attributes, such as area, density, mean size and proportion of alien or indigenous, with socio-economic attributes of the towns. The area and state of current public green space varied markedly between the towns, with the poorer towns faring the worst. Lower income levels were significantly negatively correlated with the area and quality of public green space. Despite this, human population density and per capita green space were the best predictors of the proportion and mean area of public green space present in the towns. The proportion of town green space and the per capita green space were the best predictors of changes in woody plant composition and density.

  • Description: The main aim of the project is to investigate the feasibility of artificial recharge of the Bushmans River Mouth Aquifer in the Eastern Cape. The suggested method of recharge is through natural infiltration through a series of wetlands in the back dune area. The proposed site was the Klipfontein Vlei which is located just north of the Bushmans River Mouth. Artificial recharge is defined as augmenting the natural movement of surface water into underground formations by some method of construction, the spreading of water, or by artificially changing natural conditions. A variety of methods have been developed, including water spreading, recharging through pits and wells, and pumping to induce recharge from surface water bodies. The choice of a specific method is controlled by local topography, geology and soil conditions, and the quantity of water to be recharged and ultimate water usage. In special circumstances, land value, water quality, and climate play an important role. Artificial recharge is not a foreign concept to South Africa and this project is to test its feasibility in a back dune wetland area. Augering done in the study area revealed the dominance of sandy loam in the upper layers of the pans, loamy sand in the middle levels and the presence of some sand lenses in the lower reaches. Particle size analysis done by sieving and hydrometer test, showed a dominant 3f fraction. There was variation in modes in pan 1 from unimodal to bimodal to trimodal. Pan 2 showed no variation as all samples were unimodal and moderately well sorted. Infiltration tests were done by a double ring infiltrometer. These results showed that the infiltration rates of the pans became stable after 15 to 20 minutes, thus indicating that the soil had reached its saturation point. The resistivity surveys revealed a stepped water table. The inclination of the water is controlled by the predominately argillaceous horizons of the Bokkeveld Group. Based on the above results, it is recommended that the Klipfontein Vlei be used as an artificial recharge site.

  • Description: The dusky kob, Argyrosomus japonicus, is a popular South African “line fish” whose stocks have dwindled to dangerously low levels of between 1% and 4.5% of pristine spawner biomass per recruit. A. japonicus stocks are currently managed by means of minimum size restrictions and daily bag limits, and as a result of the inability of these measures to facilitate the recovery of the species over a realistic time frame, the need for an alternative management plan has become apparent. Given the status of the stock and management regime, stock enhancement appears to be an appropriate option to be investigated. This study evaluates the feasibility of stock enhancement as a possible management tool to assist with the recovery of this important South African linefish species. By evaluating the genetic and ecological implications related to stock enhancement, identifying a suitable tagging method for post-release monitoring, and evaluating the economic feasibility of such a programme, any fatal flaws would become immediately apparent. This coupled with the required framework for the development of a management plan for stock enhancement of A. japonicus provides direction further research and actions required in order to utilise stock enhancement as a management tool. Due to the nature of stock enhancement, there are several ecological and genetic issues that arise from such a programme. These issues were reviewed and the issues that were relevant to stock enhancement of A. japonicus identified. Ecological concerns that arose included those of competition, disease and seed quality, while genetic issues were concerned mainly in the possible loss of genetic variability and consequent reduction in fitness of the stock. Fortunately the technology exists to evaluate the effects and likelihood of these problems occurring as well as to minimise the likelihood of them occurring. By taking a scientific approach to stock enhancement, hatchery management, and release strategies can be manipulated in such a way as to minimise any negative effects that may be caused. Both ecological and genetic effects of stocking indicate a need for post-release monitoring of stock enhancement programmes. Stock enhancement requires a post-release monitoring programme, which in turn relies on an ability to distinguish between hatchery reared and wild fish. A study was conducted to evaluate the suitability of coded wire tags (CWT), visual implant fluorescent elastomers (VIFE), and oxytetracycline (OTC) as a means of distinguishing between hatchery reared and wild A. japonicus, for the purpose of a post-release monitoring programme. OTC appeared to be the most suitable as it produced 100% retention over a five month period compared to 62% and 61% for VIFE and CWT respectively. OTC is therefore suggested as a tagging method for the purpose of post-release monitoring of the stock enhancement of A. japonicus. To evaluate a possible funding option for stock enhancement of A. japonicus in South Africa, a willingness-to-pay survey, based on a “user pays” approach using recreational fishing permits as a vehicle for payment, included 102 recreational anglers in the Plettenberg Bay area. The survey showed that generally anglers were willing to pay more than the current amount for the recreational fishing permit. This promising result, coupled with the fact that there are approximately 450 000 recreational anglers leads to the belief that there is potential for a substantial increase in the funds generated for the Marine Living Resources Fund through recreational anglers. Stock enhancement should not be ruled out on the basis of economic feasibility yet as there is potential for it to be sustained by the users of the resource. An A. japonicus juvenile production costing model was created taking into account setup and running costs of a hatchery for A. japonicus, based on known parameters from existing facilities, and adjusting them to meet the requirements of a stock enhancement facility. Estimates varied according to the number and size of fish for release (values which can only be decided upon after further research), with setup estimated to be between R 10 000 000 and R 30 000 000 and annual running costs between R 2 400 000 and R 6 700 000 annually. These figures were dependant on the size and number of fish being produced, with production ranging between 100 000 and 5 000 000 fish of between 50 mm and 150 mm, and a broodstock of 150 individuals. Given the need for alternative management of A. japonicus in South Africa and the lack of evidence to suggest that it is an unfeasible option, this project has found no reason why further investigation into the use of stock enhancement for the management of A. japonicus should not proceed further provided the fishery is shown to be recruit limited. The technology and ability to overcome possible ecological and genetic problems exists, a suitable means of tagging for post-release monitoring exists, as does a realistic funding option. There is a substantial amount of research that must be done prior to stocking, for which a base framework is provided.

  • Description: The reintroduction of lions, cheetahs and African wild dogs to Kwandwe Private Game Reserve in the Eastern Cape Province of South Africa created the opportunity to study the biology and behaviour of these large carnivores in an enclosed system. The research focused on space utilisation and feeding ecology of the predators, using standard observational methods. Changes in the structure of the carnivore guild, and changes in the prey base that occurred during the study were used as natural experiments to examine factors affecting space use and diet. In general, the diets of the predators were similar to previous studies and prey abundance was more important than prey species size in determining prey selection. Changes in the abundance of certain prey species was matched by a dietary switch in lions from kudu to warthog and an increase in the proportion of springbok kills by the cheetahs. There was no significant difference in the proportions of prey species detected by ad hoc or continuous observations. Core areas occupied by the predators were significantly smaller than home ranges except when females were denning. Home ranges overlapped both within and between species, but there was very little overlap of core areas. An increase in the number of lion prides in the area during the study resulted in an increase in overlap of home ranges of lions and cheetahs, but did not result in a change in home range size. Space use by female cheetahs with cubs increased as the cubs grew older. The use of thicket vegetation by cheetahs decreased with an increase in the number of lion prides. Minimum Daily Energy Expenditure, energy intake and net benefit were calculated for the predators using data from continuous observations. All predators exhibited a large net benefit and the net benefit for single female cheetahs was greater than for the members of the coalition. Net benefit for the alpha pair of African wild dogs was lower than that of the pack.

  • Description: School-related mistakes and low pass rates have led this researcher to perceive that some students are not adequately prepared for Mathematics 1. To address the problem of under-preparedness overseas universities use placement or diagnostic tests. Diagnostic testing identifies areas of weakness and provides information to guide the development of appropriate remedial support. This researcher embarked on a study to identify the sub-domains (criteria) that should be included in a diagnostic Mathematics test battery at the NMMU. An analysis of first-year curricula was undertaken to determine the required Mathematical pre-knowledge and skills entry-level students should have. Thereafter, the required pre-knowledge and skills were reflected against the standard grade school syllabi. From this it was determined that the school learners should acquire the necessary pre-knowledge and skills for university success as part of the school syllabus. However, in reality this is not the case as the researcher and other Mathematics lecturers identified a number of basic errors that incoming students make. This suggests that they have not developed all the required knowledge and skills. Furthermore, their performance in the matriculation examinations does not provide an adequate measure of the requisite Mathematical pre-knowledge and skills necessary for success at university-level Mathematics. No suitable existing diagnostic Mathematics test could be found. By utilizing both an action research as well as a test development methodology, the researcher thus proceeded to delineate the sub-domains that should be included in a diagnostic Mathematics test battery. Thereafter, test specifications were developed for two pilot tests and items were developed or sourced. The constructed response item-type was chosen for the pilot tests as it was argued that this item-type was more useful to use in a diagnostic test than a multiple-choice item format, for example. The pilot test battery, which consisted of a pilot Arithmetic and Algebra and Calculus tests, was administered to a sample of first-year students at the NMMU in 2004 and their performance in Mathematics at the end of the first year was tracked. Tests were scored holistically and analytically to provide a rich source of information. Thereafter, the test results were analysed to obtain evidence on the content validity of the pilot tests, including the item difficulty values and the item-total correlations; to determine the predictive validity of performance on the pilot tests with respect to final first-year Mathematics marks; and their reliability was determined using the Cronbach’s Alpha statistic. These findings suggest that appropriate sub-domains (criteria) were delineated and the items appropriately covered these sub-domains (i.e. the content validity of the pilot tests is acceptable). Furthermore, the predictive validity of the pilot ix tests was found to be acceptable in that significant correlations were found between the pilot tests and performance in first-year Mathematics. Finally, the pilot tests were found to be reliable. Based on the results, suggestions are made regarding how to refine the diagnostic test battery and the research related to it. The final diagnostic Mathematics test battery holds much potential to be able to assist in the early identification of at-risk students who can be timeously placed in developmentally appropriate Mathematics modules or provided with appropriate remedial intervention.

  • Description: The purpose of this study was to look at how a foreign aid dependent economy is vulnerable to external manipulations. This study came up with the conclusion that foreign capital dependence is detrimental to long-term social, economic, and sustainable development of developing countries. The study also noted how foreign aid is used as a foreign policy instrument by western countries to influence the behaviour of the developing countries. The study noted that Zimbabwe is an aid dependent country hence its vulnerability to external manipulation. This has been demonstrated by capital flight from Zimbabwe since 1997. Multilateral Financial Institutions, the European Union, United States of America and other bilateral donors withdrew their financial support to the country due to policy disagreements with the Zimbabwean government. This incidence of donors withdrawing their financial support to Zimbabwe raises fundamental questions as to whether the African state is autonomous or is it possible for the African state to delink itself from the current global international market and at what costs? What has come out very clearly from this study is that a dependent state has no autonomy to decide on its domestic and foreign policies without considering the interests of its donors, and hence its vulnerability to external manipulations. , Thesis (MSoc) -- Faculty of Management and Commerce, 2008

  • Description: In response to the crisis created by the HIV and AIDS pandemic in this country, South African education departments are demanding that educators play a significant role in creating awareness amongst children and adults alike. This task is challenging for teachers who are already working under the pressure of demanding workloads. In order to achieve the intended outcome of AIDS awareness, training of highly efficacious teachers is required. The education module, PSED201, Issues in School and Society, offered as part of a BEd degree for in-service mathematics and science teachers at the Nelson Mandela Metropolitan University, provides one such training opportunity. This study investigates the impact of this module on the self-efficacy of 128 teachers with respect to their role as HIV and AIDS educators. Both quantitative and qualitative methods were used and data were collected by means of questionnaires and interviews. The results suggest that there has been an improvement in all four areas of teacher self-efficacy examined in this research. As such, it may be concluded that an important outcome of this intervention has been achieved. As highly efficacious teachers are more likely to influence the behaviour of their learners, the findings of this research should make a meaningful contribution to the debate around AIDS education in South African schools.

  • Description: Reading and understanding algorithms is not an easy task and often neglected by educators in an introductory programming course. One proposed solution to this problem is the incorporation of a technological support tool to aid program comprehension in introductory programming. Many researchers advocate the identification of beacons and the use of chunking as support for code comprehension. Beacon recognition and chunking can also be used as support in the teaching model of introductory programming. Educators use a variety of different support tools to facilitate program comprehension in introductory programming. Review of a variety of support tools fails to deliver an existing tool to support a teaching model that incorporates chunking and the identification of beacons. The experimental support tool in this dissertation (BeReT) is primarily designed to encourage a student to correctly identify beacons within provided program extracts. BeReT can also be used to allow students to group together related statements and to learn about plans implemented in any semantically and syntactically correct algorithm uploaded by an instructor. While these requirements are evident in the design and implementation of BeReT, data is required to measure the effect BeReT has on the indepth comprehension of introductory programming algorithms. A between-groups experiment is described which compares the program comprehension of students that used BeReT to study various introductory algorithms, with students that relied solely on traditional lecturing materials. The use of an eye tracker was incorporated into the empirical study to visualise the results of controlled experiments. The results indicate that a technological support tool like BeReT can have a significantly positive effect on student comprehension of algorithms traditionally taught in introductory programming. This research provides educators with an alternative way for the incorporation of in-depth code comprehension skills in introductory programming.

  • Description: The role and power of ICT today, particularly the Internet, cannot be underestimated. The Internet has a great impact on the business environment, where a large majority of companies and organisations have made substantial investments in an online presence in the form of websites, as well as the IT infrastructure needed to improve business processes. In terms of websites, research has shown that it is critical to identify the target market of the site and the actual users, and to construct the site according to their specific needs and preferences. This is to a large extent the focus of the field of Human Computer Interaction. It therefore makes perfect sense that many software products and websites fail to meet the users‟ needs, as they are designed mainly by Western designers for Eastern and African users. In essence, the failure is due to the fact that the design does not accommodate the cultural behaviours, understandings and preferences of the intended users, thus making it difficult for them to use and adopt them. This has been confirmed by many researchers who have studied various culture dimensions and their relation to Web design. As mentioned, the role of the Internet in terms of its effect in the business world is becoming increasingly important. However, the Internet could prove to play an influential role in the public sector as well and could therefore be used as a critical tool by government in the form of e-Government. Many countries are adopting e-Government initiatives in an attempt to improve their relations within government itself and with their citizens and businesses. This would help them to render better service delivery and at the same time empower the citizens to also participate in the governance of the country itself. The concept for this dissertation was formulated in terms of three key ingredients: e-Government, culture dimensions and Web design. The purpose of this dissertation is to examine the way a specific culture dimension, referred to as the cultural-context dimension, which focuses on the communication process, can impact in Web design. Once this is achieved, it will be possible to determine how this can positively affect the design of the South African e-Government website so that the overall usability of the site may be improved. The improvements will be justified because the site would then match the cultural behaviours, perceptions and Web design preferences of South African users. In short, the goal of this III dissertation is to provide guidelines and recommendations that will improve the South African e-Government website (www.gov.za) by examining anthropologist Edward Hall‟s cultural-context dimension and its role in the Web design process.

  • Description: The role of natural resources in the lives of rural children impacted by HIV/AIDS remains unexplored. This study highlights wild food use by rural children vulnerable to the impacts of HIV/AIDS as an important and regular activity that supplements their domestic diets. This work found that with an increase in vulnerability to HIV/AIDS, children rely more on wild foods. Through an 18 month project in the Eastern Cape, using a broad quantitative and qualitative school and non-school survey, individual interviews, food diaries, participant observation, interactive photography, and other participatory techniques, a total of 850 children's coping strategies and livelihoods were examined. The quality of children’s domestic diets was, on average, 60% lower than the Food and Agricultural Organization (FAO) guidelines. However, 62% of the children interviewed were supplementing their diets with wild foods, 30% having over half their diet supplemented with wild foods. Dietary diversity showed a 13% increase when wild food supplementation occurred. While traditionally rural children rely on reciprocal networks during times of crisis, we found that these networks were eroding from the pressures of HIV/AIDS. Begging, for some children, was replaced by wild food collection and a significantly larger proportion of children more vulnerable to HIV/AIDS relied on wild foods more than did less vulnerable children. Considering the heightened nutritional and energy needs of children, combined with the impact of HIV/AIDS on household food access, wild foods represent the last freely attainable food sources available to them. Hunting and collection of wild food is a group activity, which was found to have valuable psychosocial benefits. Commercialisation of wild foods was observed among 38% of the children, with significantly more vulnerable children selling wild foods. The use of wild foods by rural children also had positive influences on the preservation of indigenous ecological knowledge.

  • Description: The impact of immigrants on the labour market in the South African context has always been a long standing issue with both government and natives’ fearing for the latter’s displacement effect, pressure on wages and resources. Migrants are blamed for poor labour market conditions of a host country. Literature reviewed from Africa and elsewhere shows that migrants have negative outcomes on the host country’s labour market. For this study an Error Correction Model on time series data from 1980-2006 has been estimated. The study estimated two models that is the unemployment and the wages models. The variables used for estimation are immigration, inflation and the Gross Domestic Product. The study surprisingly found a positive impact of immigrants on wages but the effect on employment was negative and significant. It is important to note here that the calculated impact is only for the documented immigrants the impact the illegal ones is not known.

  • Description: The 1980s and 1990s saw major changes in the political landscape of the media in many countries that were either reverting or emerging from repressive nondemocratic regimes. Among the notable changes in media industry was the opening up of the national airwaves, which had been a state monopoly, to private sector and community participation. The democratic dispensation also put state broadcasters in the spot-light regarding their editorial content which was previously ‘institutionalised’ as belonging to the ruling regimes. This study set out to investigate the extent to which broadcasting reform legislation meant to address the unfair coverage of contending voices on Zambia’s public broadcaster has had an impact in reversing the situation in the newsroom. Using qualitative methods of investigation, the study established that while the ZNBC staff understand aspects of their role in their newsroom in relation to the principles of public service broadcasting and in line with the enacted legislation, they perceive that, in practice, they have to ensure that the news content still remains a reserve of a few voices in favour of the ruling regime. This was evidenced by testimonies from the news staff’s complaints of continued editorial interference in their work by government leaders and government appointed gatekeepers, as well as selfcensorship. The study recommends, among other things, the full implementation of the recently enacted laws on the operations of ZNBC in order to achieve some minimum levels of being a public broadcaster. It further recommends a serious re-orientation of the ZNBC newsroom and management staff to the current legislative requirements so as to shift their mindset away from their traditionally-held views of thinking that news at that station is only for the ruling regime.

  • Description: Selecting actors to appear in an advertisement is an important decision which has a crucial impact on the effectiveness of an advertising campaign. The same message, delivered by different actors, produces varying outcomes among consumers. This dilemma concerning the choice of actors occurs particularly in multi-racial societies, such as South Africa, where advertisers have to target different sectors of the community. In multi-racial societies, the choice of actors in advertisements goes beyond the usual commercial reasons. Indeed, two dimensions are generally conferred to multi-racial advertising. Firstly, the use of multi-racial representations allows for the targeting of a wider population that also owns a wider purchasing power. Marketers who want to market their brand use, for example, white and black actors so that white and black consumers can identify with the actors and recognize themselves as the target of the advertisement. Secondly, the multi-racial representations of this type of advertising hold a social role that counteracts the segregated depiction of the society. Consumers who are exposed to a multi-racial advertisement might perceive this social dimension and attribute a social responsibility to the advertisement. The purpose of this thesis is to examine the influence of the above dimensions on the effectiveness of a multi-racial advertisement. On the one hand, this study investigates the Identification Process followed by a consumer exposed to a multi-racial advertisement. On the other hand, it examines how consumers attribute a social responsibility to a specific multiracial advertisement and how this attribution, in turn, influences their responses to the advertisement and brand. Finally, the impacts of both of these dimensions on consumer behaviour are compared and the most persuasive dimension is identified. This thesis draws on Attribution Theory and Identification Theory in arguing that there are strong economic imperatives for adopting a multi-racial advertising approach. The thesis develops a conceptual framework and tests empirically hypotheses regarding the key constructs and moderating variables. The empirical results point out that both dimensions symbiotically influence the effectiveness of a multi-racial advertisement. Specifically, the results highlight that the social responsibility attributed by the viewers to the advertisement influences their behaviour more than the Identification Process.

  • Description: The role played by medical doctors and the employment positions they hold in South Africa and in the world today has shifted from being clinical only to include management. They were once only responsible for patient care, now are responsible for their organization's management. Physician managers have difficult tasks for which medical school provides no preparation. Doctors in an assortment of roles take on management responsibilities to varying degrees: these may be a single-handed private practitioner or lead a small clinical team; or a clinical or medical director or a chief executive; or hold senior management positions in National or Regional Legislature. Some are also managing and supervising colleagues in public or private hospitals and are responsible for managing budgets, allocation of resources; developing policies and making other management decisions. These roles require knowledge and competence of managerial skills in order to facilitate and lead in an effective and efficient manner. This study revealed that medical doctors, as business owners, in Mercantile Hospital are running their businesses, the medical private practices, without any managerial skills’ training. There was a general consensus that there is a need for managerial skills in any business and the respondents confirmed that managerial skills are important and necessary for the successful achievement of goals in a medical private practice.
