  • Description: Object oriented databases have been gaining popularity over the years. Their ease of use and the advantages that they offer over relational databases have made them a popular choice amongst database administrators. Their use in previous years was restricted to business and administrative applications, but improvements in technology and the emergence of new, data-intensive applications has led to the increase in the use of object databases. This study investigates four Open Source object-oriented databases on their ability to carry out the standard database operations of storing, querying, updating and deleting database objects. Each of these databases will be timed in order to measure which is capable of performing a particular function faster than the other.

  • Description: Education policies remain a contested terrain in both the social and political environments. They are not neutral instruments and are used both to maintain the existing social order and also to promote varying kinds of change or mobility. The South African Schools Act, 1996 (Act 84 of 1996) hereafter SASA, which is the source of all policies that regulate school issues in South Africa promotes democratic methods of school governing and education provisioning that favours the previously disadvantaged groups. The NNSSF is one of the policies of SASA that makes schooling accessible to the poor through school fee exemptions while attempting to close the gap between the rich and the poor through differentiated school funding created according to researched poverty levels and standardized target lists. This has been designed to fulfil one of the essential human rights of man- education that has been entrenched in the Bill of Rights of the Republic of South Africa Constitution, 1996 (Act 108 of 1996) hereafter, Constitution. Thus, the study’s objective is to evaluate the implementation of the NNSSF policy in public schools focussing on school fee exemptions. The extent to which poor parents and learners are given school fee exemptions as they are supposed to according to the policy will be indicators of whether the NNSSF is justly or unjustly implemented in public schools. Learners are the recipients of the right to education. Parents are given the responsibility to fund the education of their children. However, for poor parents to fulfil that they need advice and assistance from the teachers and SGBs to be able to access the school fee exemptions while they have a right to just administrative action and to human dignity in dealing with them. SGBs and teachers have to create a favourable environment for the just implementation of the NNSSF by advising and xiii assisting deserving parents and learners to access school fee exemptions so that the right to education is fulfilled. The duty of in loco parentis and acting in the best interest of the child enforce teachers to do everything possible to ensure that learners access education. EDOs are supposed to guide, monitor and supervise the implementation of the policy while legal bodies should assist parents and learners to demand their right when it is violated through litigation. The study used the method of survey which is quantitative and interviews which are qualitative. Questionnaires and interview schedules were tools used to collect data that was analysed through statistical methods and represented in the form of tables and pie-charts. Various significant findings were made that had a bearing on the implementation of the NNSSF policy in public schools, most important to note is that some learners who have the right to education are aware of this right but do not know how to ensure that it is not violated. Parents are not given the opportunity to decide whether school fees should be charged in their schools. Above that they are not given the advice they need to be able to access school fee exemptions. Some teachers think that by advising and assisting learners and parents they will be buying cheap popularity- showing ignorance. EDOs do not know how schools implement the NNSSF, they are not involved in anyway. Thus the study views the implementation of NNSSF policy in public schools as unjust and recommends that SGBs and teachers need to be educated, guided and monitored by the EDOs on the policy and its implementation. They in turn will have to educate parents and learners so that they are able to access school fee exemptions thereby receiving education – their right.

  • Description: Dwesa is a rural town situated in South Africa's Eastern Cape Province that has been selected as a testing site for an e-commerce project to address some of the challenges faced by the community. These challenges include difficulties stemming from poverty, poor access to public services, unemployment and low levels of literacy. The Siyakhula Living Lab project’s aim is to develop an e-commerce platform that will 'connect' the residents with the necessary access to services and markets by providing them with the necessary tools that can help in alleviating some of their challenges. In order for the project to achieve its objectives, a deeper understanding into the needs of the prospective users is required. User requirements elicitation deals with the process of interacting with the prospective users to understand and document their needs. This research aims at evaluating existing requirements elicitation techniques and methodologies in the context of rural information technology implementations. The primary objective is to develop a model for user requirements elicitation in Dwesa. Many requirements elicitation techniques and frameworks exist, but few have been evaluated in the context of rural software implementations. Requirements elicitation techniques should not be applied simply as steps to gather information. Instead this research project proposes a model that can be applied to assimilate the contribution of knowledge regarding the stakeholders, problem and solution characteristics, and other characteristics into the software development process for the effective elicitation of requirements.

  • Description: Smartphones are proliferating into the workplace at an ever-increasing rate, similarly the threats that they pose is increasing. In an era of constant connectivity and availability, information is freed up of constraints of time and place. This research project delves into the risks introduced by smartphones, and through multiple cases studies, a maturity measurement model is formulated. The model is based on recommendations from two leading information security frameworks, the COBIT 4.1 framework and ISO27002 code of practice. Ultimately, a combination of smartphone specific risks are integrated with key control recommendations, in providing a set of key measurable security maturity components. The subjective opinions of case study respondents are considered a key component in achieving a solution. The solution addresses the concerns of not only policy makers, but also the employees subjected to the security policies. Nurturing security awareness into organisational culture through reinforcement and employee acceptance is highlighted in this research project. Software consultancies can use this model to mitigate risks, while harnessing the potential strategic advantages of mobile computing through smartphone devices. In addition, this research project identifies the critical components of a smartphone security solution. As a result, a model is provided for software consultancies due to the intense reliance on information within these types of organisations. The model can be effectively applied to any information intensive organisation.

  • Description: The aim of this dissertation is to extract information from shipwreck survivor narratives, which will add to the known body of knowledge of the pre-colonial history of Southern Africa during the years 1552 to 1782. The discourse analysis focuses on the voice of the African peoples where the Europeans are the 'Strangers', the 'Other', reversing the view that the people of non-European cultures were termed as the 'Other'. Indigenous inhabitants of south-east Africa, south of Kosi Bay, first encountered Europeans in 1552 when a Portuguese ship was wrecked at present-day Port Edward. Subsequently, eight more Portuguese ships were wrecked between Plettenberg Bay and Kosi Bay between the years 1554 to 1647. Two Dutch ships landed on the shore, one south of the Bay of Natal in 1686, and the other being wrecked near the mouth of the Keiskamma River in 1713. There were also two English ships, with one striking the rocks on Bird Island in Algoa Bay in 1755 and the other, the more famous Grosvenor of 1782, coming aground at Lambazi Bay, north of the Mzimvubu River. The survivor groups were large, varying in size from 72 to 500, and most included a large complements of slaves. The survivors of the Portuguese ships made their way to present-day Mozambique where the Portuguese had trading outposts. The survivors of the Dutch ships, as well as those of the Grosvenor tried, with limited success, to make their way to Cape Town. The survivors from two of the Portuguese wrecks and the English group on Bird Island, constructed small ships and managed to sail away.

  • Description: The main aim of this study was to assess the impact of the Best Management Practices (BMP) project on social and economic wellbeing at Zanyokwe Irrigation Scheme (ZIS) in central Eastern Cape Province. The BMP project is a knowledge-based initiative aimed at introducing management practices (mainly soft skills) in order to improve production and livelihoods in the study area. The study employed a survey to collect socio-economic data amongst farming households. The 2005 situation analysis, which was conducted amongst the same respondents before the introduction of the new practices allowed for comparisons in order to track changes or impacts after the implementation of the project. Also, the social and economic impact assessment (SEIA) framework was used to assess the impacts. The results of the impact assessment showed the BMP project to have an impact on social and economic well being of households. The skills introduced were in the areas of water management, agronomic practices, marketing and institutional arrangements. More than 90% indicated that there was improvement in agronomic practices and water management and 68% in marketing. More than half of farmers worked in their farms on a daily basis, which is a big change as none of the farmers worked during weekends in 2005. The average time spent on the farms also increased from four (in 2005) to seven hours (this investigation) on average per day. The BMP project also had a positive impact on social relationships and networks between farmers and the BMP project team as well as well as farmers and non-farmers. Land use intensity improved due to increases in acreage of main crops as well as cultivating at both seasons. More than 40% of farmers cropped their land at both seasons (winter and summer). In 2005, most of the land was fallow in winter. While some of the new practices introduced had a negative impact on input expenditures, the returns were positive. These extra efforts and expenditures resulted in improvement in incomes. Agricultural contribution to household income increased from 71% in 2005 to 81% in 2007. The increase in household incomes had a positive effect on poverty and food security status of households. The proportion of households earning incomes that are below poverty line dropped from 61% in 2005 to 38% in 2007. Changes in the diet of the households were noticed. In addition to the consumption of staples such as samp, maize meal and rice, people added a variety of vegetables. Own production was the main source of these vegetables as was indicated by 66% of respondents compared to only 25% in 2005. Food remained the main expenditure category though, as was the case in 2005. Improvements in marketing such as performing extra marketing functions and adopting a marketing strategy (collective action) also led to improvements in economic wellbeing.

  • Description: The increased abscondment of Mental Health Care Users from institutions of care, treatment and rehabilitation has prompted the researcher to conduct the study because patients who are not visited do not stand a chance of getting a Leave Of Absence (LOA). Problem: The concern is the danger of assault, murder, rape and other high risk situations the mentally ill individuals and the community are exposed to, which is caused by frequent abscondment of mentally unstable individuals who roam around the community without proper treatment and care. This is caused by failure of the relatives in coming to request patients for leave of absence (LOA). Purpose: The study investigated the effects of mental illness on relationships amongst families with the mentally ill members. The number or frequency of visitations by relatives to the mental health institutions is used by the researcher, to measure the nature of relationships between families and the psychiatric patients related to them. Method: The population comprised families of the mentally ill persons admitted at Cecilia Makiwane mental health units. The sample was collected conveniently as relatives came to visit the mentally ill until the desired number was reached. The designed tool was a questionnaire which was self administered. Data were analysed manually. Tables and graphs are shown in the results. Conclusion and Recommendations: The study revealed that approximately 100% of respondents had a lack of knowledge about mental illness and the mentally ill, in terms of care, treatment and rehabilitation hence they all need assistance in dealing with the mentally ill in the community. Findings also revealed that mental illness causes breakdown in family relationships. Recommendations regarding the enhancement of relationships between families and their mentally ill members are formulated as coping skills in the dissertation. The burden of having to deal with mentally ill person whose illness is not understood can lead the family to a state of confusion and iv not knowing what to anticipate. Lack of resources compounds the problem as the family members are not able to visit the ill member due to lack of funds (Baumann, 2007:637). The families with a mentally ill member usually shoulder the greatest part of the burden of mental illness (Uys and Middleton, 2004:77); unfortunately, lack of resources pose a problem.

  • Description: In recent years, concern about food safety linked to health issues has seen a rise in private food safety standards in addition to the regulations set by the Food and Agriculture Organisation (FAO) in collaboration with the World Health Organisation (WHO). These have presented challenges to producers and exporters of agricultural food products especially the producers of fresh fruits and vegetables. In spite of the food safety-linked challenges from the demand side, the vast range of business-environment forces pose equally formidable challenges that negatively impact on the exporting industries’ ability to maintain or improve their market shares and their ability to compete in world markets. The objective of this study was therefore to establish the competitiveness of the South African citrus industry in the international markets within this prevailing scenario. Due to the diversity of the definitions of competitiveness as a concept, this study formulated the following working definition: “the ability to create, deliver and maintain value and constant market share through strategic management of the industrial environment or competitiveness drivers”. This was based on the understanding that the international market shares of an industry are a function of forces in the business environment which range from intra-industry, external and national as well as the international elements. The unit of analysis were the citrus producers engaged in export of their products and the study made use of 151 responses by producers. The study adopted a five-step approach to the analysis of the performance of the South African citrus industry in the global markets, starting with the analysis of the Constant Market Share (CMS) of the South African citrus industry in various world markets, establishing the impact of the business environmental factors upon competitiveness, establishing the costs of compliance with private food safety standards, determining the non-price benefits of compliance with the standards, as well as highlighting the strategies for enhancing long-term competitiveness of the industry in the international markets. South Africa is one of the top three countries dominating the citrus fruit export market. Since its entry into the citrus fruit exports market in the 1900s, the industry has sustained its activity in the international market. The Constant Market Share Analysis shows that, amidst the challenges on the international market side, and the changes in the business environment, over much of which the industry has limited control and influence, the industry has maintained its competitive advantage in several markets. The CMS shows that South Africa’s lemons are competitive in America. Despite a negative trend, the South African grapefruit has been competitive in France, Greece, Italy, the Netherlands and Spain. Oranges have been competitive in the Greece, Italy, Portugal, UK, Asian and Northern Europe markets. Competitiveness in these markets has been due to the inherent competitiveness of the industry. Competitiveness in such markets as the Middle East has been attributed to the relatively rapid growth of these markets. The South African citrus industry has similarly undergone many major processes of transformation. The business environmental factors influencing its performance have ranged reform to the challenges beyond the country’s borders. These factors directly and indirectly affect the performance of the industry in the export market. They have influenced the flow of fruits into different international destinations. Of major concern are the food safety and private standards. Challenges in traditional markets as well as opportunities presented by demand from newly emerging citrus consuming nations have seen a diversification in the marketing of the South African citrus. The intensity of competition in the global market is reflected by the fluctuations in the market shares in different markets as well as the increase and fluctuations of fruit rejection rates in some lucrative markets such as America. A combination of challenging national environmental forces and stringent demand conditions negatively impact on revenues especially from markets characterised by price competitiveness. This study identified cost of production, foreign market support systems, adaptability, worker skills, challenges of management in an international environment and government policies such as labour and trade policies as some of the most influential obstacles to competitiveness. Some of the most competiveness-enhancing factors were market availability, market size, market information, market growth and the availability of research institutions. However, compliance with private standards still poses a challenge to the exporters. The different performance levels of the industry in various markets prove the dissimilarity of the demand conditions in the global market. These are supported by the negative influence associated with the foreign market support regimes as well as the challenges associated with compliance with private food safety standards. While market availability, market growth, market information and size were identified as enhancing competitiveness, the fluctuations and inconsistencies in the competitiveness of the industry in different foreign markets require more than finding markets. Resource allocation by both the government and the industry may need to take into account the off-setting of the national challenges and support of farmers faced with distorted and unfair international playing fields. Otherwise, market availability is not a challenge for the industry save meeting the specifications therewith as well as price competitiveness which is unattainable for the South African citrus producers faced with high production costs. For the purposes of further study, it is recommended that account should be taken of all the products marketed by the industry (including processed products such as fruit juices) in order to have a whole picture of the competitiveness of the industry in the international market. This study also proffers a new theoretical framework for the analysis of the business environment for the citrus industry and other agro-businesses. This framework takes into account the indispensability of the food safety standards and measures as well as the diversity of the global consumer and the non-negotiability of food trade for the sustenance of the growing population.

  • Description: Fleas are one of the major external parasites affecting free range chickens, causing irritation, tissue damage, blood loss and toxicosis which in turn affect quality and quantity of meat and egg production. There are many commercial insecticides available that are effective against fleas. These commercial insecticides have, however become expensive to most resourcelimited farmers and therefore unaffordable, causing farmers to seek low cost alternatives. This study was conducted to document, determine the existence of external parasites in freerange chickens and validate the alternative remedies used in controlling free-range chicken fleas by resource-limited farmers. A questionnaire survey was used to collect data on external parasites of free-range chickens and ethno-veterinary control remedies used by resourcelimited farmers to control these parasites at Amatola basin, in Eastern Cape, South Africa. Resource-limited farmers perceived that mites (79.6%), fleas (64.5%), lice (10.8%) and ticks (6.5%) were problematic parasites of chickens. To control these parasites, resource-limited farmers commonly use ash (28%) madubula (13% carbolic acid) (26.7%), Jeyes fluid (13% carbolic acid) (10%), paraffin (8.4%), used engine oil (2.8%), plants Tagetes minuta, Clutia pulchella, Calpurnia aurea (5.2%) and a few (4.2%) used commercial drugs Karbadust (Carbarly 5%) and mercaptothion 5%. About 7.5% of the respondents used neither of the remedies. To confirm the farmers’ perception on problematic external parasites of free-range chickens a diagnostic survey was conducted. Fifty free-range chickens were randomly selected and examined for external parasites. About 96% of the free-range chickens examined harboured at least one species of external parasites. Fleas (Echidnophaga gallinacea) (50.7%) were the most prevalent followed by lice, Menopon gallinae (12.4%); Menacanthus stramineus (5.3%) and Knemidocoptes mutans (0.57%). Given that Jeyes fluid, used engine oil, paraffin, C. aurea, C. pulchella and T. minuta were mainly used in controlling these parasites, it was important to determine the potential dermal irritant effects of these plants. A dermal irritant effect test was, therefore, conducted using a rat model. Forty eight rats, with parts of the backs shaven, were used to screen the materials for irritation. All the materials tested did not cause any visible skin irritation on rats (p>0.05). Regarding that ethnoveterinary materials were non irritant on rat skin in vitro repellency and contact bio-assay models were used to assess the insecticidal properties of Tagetes minuta, Calpurnia aurea, Clutia pulchella, used engine oil, paraffin and Jeyes fluid on fleas. For the in vitro bioassay T. minuta and Jeyes fluid at 100% concentration demonstrated a repellency level of 76 and 83%, respectively. Tagetes minuta was the most effective among plant materials (p<0.05). Clutia pulchella, C. aurea, used engine oil and paraffin showed insignificant repellency (p>0.05). For the contact bio-assay, C. pulchella, C. aurea and T. minuta at a concentration of 100% resulted in flea mortality of 83.5, 73.3 and 42.5%, respectively. The efficacy of Clutia pulchella compared well with that of Karbadust which had a mean mortality of 97.5%. Paraffin, used engine oil, and Jeyes fluid (19.2%) caused higher flea mortality of more than 82%. In the in vivo study 60 free-range chickens were artificially infested with fleas and test materials were topically applied on infested sites. Test materials exhibited varying flea load reduction efficacy. Used engine oil and Jeyes fluid at 76.8% concentration had a reduction efficacy of 100 and 96% after 3 days post application of test materials. These were not significantly different to that of the positive control Kabadust (carbaryl 5%). The plants C. pulchella and C aurea at 100% concentration had an efficacy of 92 and 77%, respectively. The commonly used remedies by resource-limited farmers to control fleas vary in efficacy. Some of the materials are as effective as the commercial insecticides hence they have a potential to be exploited as insecticides. Further investigations on plant compounds with insecticidal properties and their toxicity, need to be conducted before the plants are recommended for use.

  • Description: Small and Medium enterprises (SMEs) play an important role as employers and in the economic growth of South Africa and in Africa as a whole. SMEs comprise over 90 percent of African business operations and contribute to over percent of African employment and GDP. SMEs sector has shown positive signs in South Africa, Mauritius and North Africa. SMEs constitute 95 percent of formal manufacturing activity in Nigeria. Senegal and Kenya have provided an environment which is conducive for SMEs (African Development Bank 2005). In August 2006, flood damage to small businesses and residential premises in the Nelson Mandela Metropolitan Area was estimated at R120million (SABC News 2006). The holding of an insurance cover by SMEs is crucial and beneficial to the economy and to the survival and success of the Small and Medium Enterprise sector. If a business has an insurance policy and a relationship with its insurer it becomes easier for the company to over come such a catastrophe. However, literature has shown that insurance companies are not willing to insure SMEs and it is the aim of this research to establish whether a relationship between the two constructs exists. An article entitled New Deal In The Offering for SMMEs, the author stated that the insurance industry prefer to deal only with established businesses (Mthimkhulu 2008). The aim of this research is to establish the importance of business relationship between Insurance companies and SMEs. The research will show how beneficial such a relationship is to both industries. The data for the research was collected through a survey type structured questionnaire that was developed and validated. The questionnaire was administered to the owners or managers of SMEs in the Nelson Mandela Metropolitan Area. The primary objective of this research was to establish whether SMEs in the Nelson Mandela Metropolitan Area have insurance policies for their businesses, and the results have shown that most of the SMEs in the Nelson Mandela Metropolitan Area do not have insurance policies for their businesses.

  • Description: In this study, it was attempted to gain insight on coordination of decentralized health and social development services. Further, it was attempted to evaluate the coordinating arrangements of and relationship between decentralized provincial health and social development services with similar services rendered by district and local municipalities. Since the literature on coordination of decentralized services is limited, it is anticipated that this study will provide valuable information for further research on the topic. In the literature study undertaken however, it was evident that coordination of services increases the rate of effectiveness and efficiency in the delivery of public services. It was found that role players can no longer afford to work in different compartments. They need to work cooperatively together in achieving unity of purpose, unity of effort as well as unity of action towards the realization of the objectives of government, that of rendering of public services. Thirty four respondents composed of mayors in Amathole District Municipality and Buffalo City Local Municipality, municipal managers for the respective municipalities, portfolio heads for health and social development services in the respective municipalities as well as two councillors, one in each municipality, were given questionnaires to complete. Also given questionnaires to complete were the political office bearers of the Provincial Department of Health and the Provincial Department of Social Development as well as respective Heads of the two departments. Again, officials of the five decentralized offices of the Provincial Department of Health and the Department of Social Development namely, Mbashe, Mnquma, Buffalo City, (v) Amahlathi and Nkonkobe, were given questionnaires to complete. The intentions of the study were to determine the effectiveness in coordinating the rendering of health and social development services between the Provincial Authority, the district as well as local municipalities in the Eastern Cape. Also, the intention was to determine the problem areas in the coordination of the health and social development services rendered by the above authorities. Lastly, the intention was to ascertain whether or not proper measures and standards are put in place for the effective coordination of health and social development services rendered by the above authorities. The findings of the study confirmed firstly, that there is a need to coordinate decentralised health and social development services with similar services rendered by district and local municipalities as well as other role players. Secondly, the study confirmed that departments and municipalities experience problems of coordinating decentralised health and social development services. Thirdly, the study confirmed that there are measures in place to coordinate decentralised health and social development services with similar services rendered by municipalities and other role players. Lastly, the study confirmed, that such measures are not properly defined and need to be strengthened.

  • Description: The aim of this study is to explore the experiences and evaluations of young male offenders who were diverted to family group conferencing in order to improve current services. An exploratory research design was chosen to obtain an understanding of what these young male offenders experienced during their conferencing and also to seek out their recommendations for future improvement of the family group conferencing diversion programme. This study comprised two samples which were purposively selected. The first sample was made up of ten young male offenders and the second sample comprised of the parents and /or guardians of the young male offenders. The data was collected using structured interview schedules. The data was collected on separate occasions for the two samples. Each interview lasted about 30- 40 minutes each. The findings of this study showed that there is still a need to train probation officers on appropriate implementation of family group conferencing and that families also have a role to play towards succefull implementation of diversion programmes. It is evident from the findings that young offenders need their families to support and care for them during difficult situations, as purported by the systems theory whereby society is regarded as a system with different parts and families are an important part of this system. Young offenders belong to families and families are part of communities and society. It is also important to note that victims are part of families, thus also part of society and the system. Family group conferencing provide an opportunity for all these parts to meet in a mediated environment to address the harm caused and make amends. The findings of this study also showed that there is a need to educate the general public about child justice legislation and the emerging trends in the field of child justice including diversion programmes.

  • Description: The aim of this study was to explore the roles of the parent SGB members in the School Governing Bodies (SGB) of two selected rural primary schools in the King Williams Town District. This was achieved by applying the qualitative approach within the parameters of the interpretivist paradigm. Structured interviews, semi structured interviews, document analysis and non-participatory observation methods were used at two sites that were purposely sampled. The samples in both schools were made up of SGB chairperson, SGB secretary, treasurer, one additional member, principal and non SGB parents. From the findings it emerged that the principal and SGB chairperson work in partnership in the business of school governance. However, principals seemed to dominate their SGB chairpersons who in most cases seem to be less competent than the principals. Parent SGB members seem to be dependent upon the educators in most cases on issues of school governance and they do not differentiate between their role and that of the SMT. Most SGB subcommittees seem to be dysfunctional and it was clear from the data that educators were the persons who dealt with school finances and matters of procurement. The majority of parent SGB members do not know what policies the school must adopt.

  • Description: South Africa has, since 1994 undergone significant political, social and economic changes and all these changes have had an effect in most of the governmental departments. One department adversely affected in particular, is the Department of Education (DoE). The implementation of a large number of educational policies being developed at national and provincial levels to bring about radical changes, leave much to desire. That has led the researcher to be investigating Teachers’ Formative Assessment Practices in Grade 9 Technology classrooms of selected schools in the Fort Beaufort District of Education. The DoE had explored ways to better educate learners and to improve the entire school performance, hence the introduction of the new methods of assessment, to quote but one, assessment policy No. 19640 of 1998. The new assessment policy in the GET Band is a means of assessing learners in order to enhance individual growth and development; to monitor the progress of learners; and to facilitate their learning. This policy states that assessment and feedback are integral to the teaching and learning process and policy planners and practitioners must be adequately prepared to implement these policies. Assessment is the most powerful lever educators use to influence the way learners respond to teaching and behave as learners. It is crucial that appropriate and effective methods of assessment are employed to ensure effective learning. Therefore, the study examined, within the interpretive paradigm and taking a constructivist approach, experiences and concerns raised by participants concerning the implementation of formative assessment in the case. In order to investigate teachers’ perceptions and the implementation of formative assessment practices, in relation to emerging educational policies, one Grade 9 learning area – Technology - in five schools were purposefully sampled. Data from the participants were mainly collected employing qualitative methods, being in-depth interviews, observations and document studies. The main findings of the study were that participants’ (School Management Team members, teachers and learners) perceptions were not quite clear pertaining to what formative assessment is all about. They did not know how to implement it in their classes and as a result had a negative impact on them. This led to recommending that these practitioners must adequately and rigorously be re-trained in implementing the policy. The DoE ought to outsource such trainings to tertiary institution for certification purposes. In future, the DoE should, before implementing any policy, make sure facilitators know the policy, are adequately and thoroughly trained and skilled before embarking on any further training of policy practitioners.

  • Description: Many secondary schools in the Eastern Cape and else where in South African are facing a drop out crisis but a proportion of these dropouts return to school to complete their education. The kind of social experiences that dropouts have as they reenrol and reintegrate in school remains an under-research aspect in the discourse on education access. The purpose of this study was to investigate the factors that prompted dropouts to reenrol in school and the social life experiences of these learners in school. It was also to explore school leaders‟ reactions towards these experiences, and the implications for school leadership of the dropouts‟ experiences. Using qualitative methodologies, involving a sample of 15 dropouts and two school leaders, the study found multiple motives, associated with individual characteristics of dropouts and the institutional characteristics of their family and the labour market, prompting reenrolment. Institutional characteristics at the school level were not featured. Regarding social life at school, it found that while some participants had positive social experiences, which reinforced their motivation to pursue their education, others experienced the school context as socially hostile. The nature of the social hostility is described, but school leaders seem insensitive to many of the social integration challenges that confront dropouts. Several implications for school leadership have been drawn out, including the view that while there are a variety of leverage points for addressing the social hostility problems, the social development of dropouts who experienced hostility stand to wither if supportive measures are not implemented to help them reintegrate. While the research provides new insights into the experiences of dropouts in school, it had the limitation of being a case study whose findings cannot be generalised.

  • Description: The study investigates teachers’ perceptions of their professionalism and how this professionalism is observed by both teachers and school community. The investigation takes place at three Junior Secondary Schools. In composing the research, the researcher adopted a qualitative and quantitative approach based on an interpretive paradigm. The study is concerned with how teachers view themselves as professional people. Since the extent of teachers’ professionalism is always questioned by the school community, teachers’ professionalism is not guaranteed to be easily accepted and recognised. The findings reveal that teachers in general accept the fact that they face an enormous challenge in performing their duties as they are required to act professionally and ethically at all times. SACE, the education “watchdog” has further strengthened the issue by proclaiming legally enforced ethical standards for teachers in South Africa. The study describes how teachers who joined the teaching profession for different reasons conceptualise teacher professionalism differently from each other but also agreeing on other issues. The findings of this study also show how educational policies, teachers’ conditions of service, personal beliefs and relationships between parents, learners and teachers can influence teacher professionalism.

  • Description: The study sought to establish the impact of using the local content policy in reducing television cultural influences on Mbare youth in Zimbabwe. It is assumed that television has ideological and hegemonic functions which have come to dominate the life styles of the youths on issues of dress styles, musical tastes and language, thus threatening and weakening the long established local cultures. Hence the Zimbabwean government’s local content policy was established to reduce influences of alien cultures. This study, therefore, sought to establish if Mbare youth cultures confirm or reject the imitation of television cultures with regard to dress styles, music tastes and language. In addition, the investigation aimed at establishing the feasibility of using the local content policy to reduce foreign cultural intrusions vis-à-vis globalisation challenges. The three theories utilised in the discussion of the influence of television on Mbare youth culture in this study include the cultivation theory, the theory of hegemony and the uses and gratification theory. A qualitative study was adopted to gather data using focus group discussions, questionnaires and semiotic analysis. The sample of the study consisted of 87 participants and 4 Youth.com programmes. The study revealed that television has ideological and hegemonic functions. As such, it tends to be a dominant influence on the life styles and culture of Mbare youths. The study also established that Youth.com influences youth culture through music. In Zimbabwe music has become the most influential aspect of Youth.com despite not being specified in the local content policy on television broadcasting. Furthermore, the study shows that the implications of globalisation on local television content are undermining government efforts to preserve local cultures through the local content policy. The primary reason for this has to do with the fact that Youth.com programme does not contain a higher quota of local content as stipulated in the policy. However, although the local content policy was viewed as a political gimmick, the the study revealed that it was necessary in view of youths’ vulnerability to television’s ideological and hegemonic influences. Nevertheless, in view of the loopholes revealed by this study, the policy requires to be revised to cater for all the essential cultural elements, such as, music, which are allowing alien cultures to penetrate local ways of life. For instance, the urban groove music has major impacts on the culture of Mbare youths.

Bare life in the Bantustans (of the Eastern Cape): re-membering the centinnial South African nation-state

  • Description: This thesis argues that 1994 did not mark a point of absolute discontinuity in the history of South Africa. More specifically, it asserts that 1994 did not signal the end of segregationism; instead of democracy leading to national integration, the Bantustans are still governed and managed differently from the rest of the country. Consequently, it is no surprise that they remain mired in pervasive, debilitating poverty fifteen years after 1994. In insisting that contemporary South Africa is old (rather than new), the thesis seeks to make a contribution to political struggles that aim to bring to an end the segregationist past-in-the-present. The thesis is arranged in seven chapters. The first chapter considers the crisis that has engulfed South Africa historiography since 1994. It traces the roots of the crisis back to some of the fundamentals of the discipline of history, such as empiricism, neutrality and historicism. It suggests that the way to end the crisis, to re-assert the relevance of history, is for historians to re-invoke the practice of producing histories of the present, in an interested, deliberate manner. Chapter 2 narrows down the focus of the thesis to (past and present) property. It suggests that instead of understanding the constitutional protection of property rights and installation of a restitution process as the product of a compromise between adversarial negotiators, these outcomes are more correctly understood as emanating from consensus. The third chapter outlines the implementation of the restitution programme from 1994 to 2008. The productive value of restitution over this period is found not in what it has delivered to the claimants (supposedly the beneficiaries of the programme), but rather in its discursive effects related to citizenship in the new South Africa. Chapter 4 considers the exclusion of dispossession that was implemented in the Bantustans from the restitution programme. It argues that this decision was not an oversight on the part of the post-1994 government. Instead it was consistent with all other key policy decisions taken in the recent period. The Bantustans have been treated differently from the rest of South Africa; they have been deliberately under-developed, fabricated as welfare zones, and subjected to arbitrary customary rule. Whereas Chapters 2 to 4 look at the production of historical truth on the side of domination, Chapter 6 and 7 consider production on the side of resistance. Specifically, they describe and analyse the attempts of an NGO to establish the truths of betterment as dispossession, and post-1994 prejudice against the victims of betterment dispossession. They serve as case studies of third party-led processes that seek to produce truth-effects from within a prevailing truth regime. The final chapter attempts to bring many of the threads that weave through the thesis together, by means of a critical consideration of human rights discourse. The chapter calls on intellectuals to establish truths in relation to the history of ongoing human wrongs in South Africa (as opposed to the rainbow narrative of human rights) Finally, the thesis includes a postscript, comprising technical summaries of each of the chapters.

  • Description: Some cyanobacteria strains have biofertilization and bioconditioning effects in soils. The objective of this study was to identify cyanobacteria with potential to improve the N fertility and structural stability of degraded soils and evaluate their effectiveness in soils of the Eastern Cape, South Africa. Isolation and characterization of the indigenous cyanobacteria strains with desirable properties was first to be undertaken because their effects are known to differ from strain to strain. Cyanobacteria strains 3g, 3v, and 7e were identified from 97 strains isolated from selected soils. Nostoc strains 3g and 3v had greater ability to produce exocellular polysaccharides (EPS) but low potential to fix atmospheric N2 (4.7 and 1.3 nmol C2H4 μg chl-1 h-1, respectively). On the other hand, strain 7e had the highest capability to fix atmospheric N2 (16.1 nmol C2H4 μg chl-1 h-1) but had the least ability to produce EPS. Evaluation of the strains was done in glasshouse studies starting with Nostoc strain 9v isolated from a Tanzanian soil, followed by the indigenous strains isolated from soils in Hertzog and Qunu, South Africa. Inoculation was done by uniformly applying cyanobacteria on the surface of potted soils at a rate of 6 g m-2. First harvest and soil sampling took place after six weeks, and the top 25 mm of the soil was mixed, replanted, and sampled again after a further six weeks (second harvest). Inoculation with Nostoc strain 9v increased soil N by 40 percent and 17 percent in Guquka and Hertzog soils, respectively, and consequently increased maize dry matter yields by 40 and 49 percent. Soil C increased by 27 percent and 8 percent in Guquka and Hertzog soils, respectively, and this increase was significantly associated with that of soil N (R2 = 0.838). Higher contents of soil C, soil N and mineral N, however, were found in non-cropped soils. Scanning Electron Microscopy (SEM) revealed coatings of EPS on soil particles and fragments of non-cropped inoculated soils, with iii other particles enmeshed in networks of filaments, in contrast to cropped and/or non-inoculated soils. The proportion of very stable aggregates was increased by inoculation but cropping with maize reduced the aggregate stability. Inoculating Hertzog soil with indigenous strains 3g and 7e increased the nitrate N in the first cropping by 49 percent and 69 percent respectively, in cropped soils. In the second cropping increases in mineral N were 41 percent and 43 percent in 3g and 7e inoculated soils, respectively. Maize dry matter yields were higher on inoculated soils both in the first and second harvest in response to the improved N status of the soil. Increases in aggregate MWD in cropped soil as determined by fast wetting, mechanical breakdown and slow wetting were 85 percent, 33 percent, 33 percent, respectively, for 3g inoculation, 64 percent, 41 percent, and 41 percent, respectively, for 7e inoculation and 60 percent, 24 percent, 50 percent for inoculation with 9v. In non-cropped soil, increases in MWD as determined by fast wetting, mechanical breakdown and slow wetting were 11 percent, 0 percent, 7 percent, respectively for 3g inoculation, 21 percent, 11 percent, and 7 percent, respectively for 7e inoculation, and 25 percent, 36 percent, and 19 percent for strain 9v inoculation. Scanning electron microscopy observations, which were confirmed by chemical results, revealed that inoculated soils had high EPS and filaments that encouraged soil aggregation and improved aggregate stability. Results of this study show that cyanobacteria strains isolated and selected for their ability to fix atmospheric N2 and produce EPS improved the fertility status and aggregate stability of degraded soils from South Africa.
