  • Description: Staff turnover affects even the best of organisations. It results in positions with high employee turnover rates being left open for months on end in other cases with other employees being appointed to act in those positions. Even after appointments are made there is a time period before appointees are proficient in the company operations and procedures. Staff turnover not only affects management but the organisation as a whole. It can sometimes lead to a decrease in organisational efficiency and a drop in the performance of the remaining staff. Employee retention is amongst the issues facing organisational managers as a result of a shortage of skilled workers, economic growth and high employee turnover. Organisations can no longer afford to leave the responsibility of retaining skilled and high performing employees to the Human Resources department. Management needs to take accountability for reducing loss of talent. The aim of this study is to improve employee retention by investigating factors that affect intention to resign in an aviation organisation. The study specifically examined how independent variables such as trust in management, organisational values, growth and advancement opportunities, effective communication, and work-life balance will influence the intent to resign of employees in an aviation organisation. An empirical study, consisting of a mail survey was conducted amongst 151 employees of an organisation in the aviation industry based across all nine provinces. The purpose was to investigate the determinants of intent to resign among employees in the aviation industry. The key findings indicate that growth and advancement opportunities and work-life balance are key variables for reducing intent to resign and thereby improving retention in aviation organisations. Trust in management, organisational values and effective communication were found to not have a significant relationship with employees’ intent to resign. Recommendations were made to management to ensure that they pay specific attention to growth and advancement opportunities as well as work-life balance in order to improve the retention of their employees.

  • Description: The main purpose of this study is to identify water stressed areas as a response to climate variability (Drought), Aridity, and water exploitation in the Raymond Mhlaba Local Municipality (RMLM) using Geographical Information Systems (GIS) and Remote Sensing (RS). This study focused on evaluating whether it is best to address the issue of drought and water stress as a municipal problem instead of a community-based problem. To achieve this, the study was attempting to establish four things: the climate condition of the municipality, whether the municipality is a drought prone area, how the surface water is being exploited in the municipality, and identify areas that should be considered water stressed areas. There are several indices used to compute water stress and the study opted for indices that can monitor climate variability, and surface water resources. Therefore, the de Martone Aridity Index (MA) was used to compute the aridity of the municipality the Standardized Precipitation Evapotranspiration Index (SPEI) to compute drought, and the Water Exploitation Index (WEI) to measure population water exploitation. Data used was from 25 weather stations provided by the Meteoblue website and water data from the department of water and sanitation. Thereafter, the Analytical Hierarchy Process (AHP) was used to determine the weights of each variables’ contribution to water stress. For validation, the Shapiro, Jarqua Bera and Kolmogorov-Smirnov tests were used and results showed that the data was normally distributed and a two-sample t-test confirmed that there was no significant difference between the measured and simulated data. According to the de Martonne there are three main climatic regions in the Raymond Mhlaba Municipality namely: the Mediterranean, semi-humid and humid region. The Mediterranean region is equally prone to drought as the humid region while the semi-humid region was a wet prone. This was contradictory to literature that expected drier regions to experience more frequent drought. However, this may have been influenced by the number of weather points that cover the humid region that is far lower than the ones covering the Mediterranean region. In addition, the municipality is 50% drought prone and would experience extreme events about 30% of the time. The study discovered that towns such as Fort Beaufort, Alice, Adelaide, and Middle drift are water stressed areas. While most of the other regions are low water users. These challenges with water stress could be reduced with the implementation of water saving mechanisms such as water tanks and the avoidance of addressing water stress as municipal challenges as opposed to a town specific challenge.

  • Description: After more than a decade since South Africa realized the importance of Information and Communication Technology (ICT) and the role it can play to deliver services, the country is still confronted by a number of challenges challenges that hinder the implementation of a fully-fledged ICT-based system in a form of electronic government to better deliver services and information. While rural development remains as one of the country’s greatest concerns, ICT is among approaches and perspectives that are recognized for not only accelerating rural development but also for providing the country’s economic growth. This research was set to investigate approaches to implement ICT solutions for rural development and service provisioning in the context of electronic government. The research focused more on the technical skills to implement such ICT systems for the benefit of rural development and e-government stakeholders that have an interest in design and development of an integrated and interoperable solution to accelerate service delivery, especially in rural communities. A mixed methods approach was used throughout the research accompanied by an evolutionary prototyping to development the desired prototype. A study was then conducted to gain an understanding of the state and the needs of rural communities to date. The results of the study yielded a number of urbanized service providers that rural dwellers need to timeously visit to consume services. Scenarios to design and develop the intended prototypes were then drawn from these results. The overall implementation of the prototypes produced an integrated platform that allows multiple disparate systems to communicate, share and use information. The qualities of the prototype are what this research recommends to relevant to stakeholders in order to implement an integrated and interoperable e-government system that elevates rural development programs and service delivery.

  • Description: This study is a quantitative study done in selected schools on teachers’ attitudes towards the implementation of inclusive education. Despite efforts to ensure quality education for all learners through inclusive education in South Africa, indications are that many learners, especially those who experience barriers to learning, are still excluded from full access to quality and equitable education opportunities in mainstream schools. Research has shown that the success of inclusive education depends upon teachers’ attitudes. It also shows that attitudes can hinder the progress of the implementation of inclusive education. The paper draws on White Paper 6 which speaks to inclusion of children with disabilities in schools. As the legislative and policy framework for the implementation of inclusive education, White Paper 6 states that “a public school must admit learners and serve their educational requirements without unfairly discriminating in any way”. The study is framed by Ajzen’s theory of planned behaviour, which suggests that an attitude towards behaviour is influenced by past experiences, previous knowledge and newly acquired knowledge. The study reflects findings from a questionnaire circulated to 75 teachers at three selected high schools, using descriptive statistics to analyse the data. Findings showed that there is no relationship between attitudes based on factors, including class size, years of experience, inadequate resource, and lack of adequate training but the main negative influence was found to be lack of support in implementing inclusive education. The conclusion is that there is no relationship between attitudes and the factors identified except lack of support. This research concludes with recommendations to address teachers’ attitudes in order to facilitate the inclusion of learners with special needs in the classroom.

  • Description: Girl child education has been a challenge for many African countries due to the patriarchal gender order of communities. This is not different in the Democratic Republic of Congo where son preference is still rife. This study sought to explore how girls in rural Lubaland in DRC experience their schooling in relation to the traditional gendered practices. A qualitative approach to research was employed within an interpretive paradigm. Young school going girls were purposively selected from two rural schools in Malemba and Mwanza. A total of 18 girls became participants to the study. Data were generated through the use of drawings and focus group discussions to explore how the girls saw themselves as girls and students at home, on the way to school and at school. This was done in order to understand how they experience their schooling lives. The findings revealed several gendered challenges that the rural girls experience daily in terms of gaining access to and succeeding in schools. The challenge of son preference and gender role stereotyping created challenges for girls at home, while lack of facilities for girls’ sexual health and long distances to school created challenges for girls on the way to school. At school the girls experienced challenge of being unable to afford school fees and corporal punishment. If these challenges are to be eradicated, there is need for all stakeholders in education, including traditional leaders and communities to deconstruct the gendered dynamics that position women and girls as subordinate and not deserving of an education. This study has implications for educational planning in the Democratic Republic of Congo for girl children to get better access and success in their education. The findings also highlight the need for more concerted efforts to understand the experiences of schooling girls across DRC in order to influence teacher training and educational provisioning that is girl friendly.

  • Description: The main objective of the study was to determine consumer perceptions and microbial quality of meat sold in the informal markets found in Nkonkobe and Buffalo City Municipalities in the Eastern Cape Province, South Africa. To determine consumer perceptions of the quality of the meat and meat products sold in the informal markets in Nkonkobe and Buffalo City Municipalities, a survey was conducted. A total of 160 consumers from two municipalities in the Eastern Cape (EC) Province of South Africa was randomly sampled and interviewed. A questionnaire was used to gather information about consumer perceptions of meat and meat products sold in the informal markets regarding their knowledge about safety, food-borne diseases, hygiene, and the quality of the meat among others. The study showed that Alice Town has a larger (66.25percent) proportion of consumers with knowledge about foodborne diseases while King Williams’s Town had a larger proportion (48.75percent) of respondents who had no knowledge about Food-borne diseases. However, a large proportion of consumers in King Williams’s Town considered vendor (82.5percent) and environmental hygiene (93.75percent) than in Alice Town. Consumers (83.75percent) in King Williams’s Town viewed the meat from street vendors to be of low quality while a small proportion (18.75percent) of consumers in Alice Town viewed it as the meat of good quality. Alice had a large proportion (61.25percent) of consumers, which had knowledge of the meat safety law than King Williams’s Town. More consumers from King Williams’s Town (31.25percent) agreed that government plays a role while Alice had a small proportion (26.25percent) which disagreed. The results also showed that consumer perceptions about the safety of meat and meat products are focused more on hygiene, neglecting other important aspects such as vending infrastructure. However, most consumers do not have enough knowledge concerning meat safety. The second study determined the microbial quality of meat sold by street vendors based in Alice and Kind Williams Town in the Eastern Cape Province South Africa. A total of 48 fresh and uncooked meat samples (beef, pork, and mutton), 48 surface contact plates and 40 water samples was collected from 4 street vendors from each town for microbial analysis (n=48). After collection, all samples were subjected to Aerobic plate count (APC), Salmonella spp, Staphylococcus aureus (Staph) and Escherichia coli (E. coli). The results revealed that Salmonella spp tested negative across all the meat samples used in the study. However, no significant differences were found in the microbial quality of meat sold by street vendors in Alice and King Williams town. Furthermore, there were no significant differences (P>0.05) between the APC of raw beef (4.8 Log CFU/g), mutton (3.7 Log CFU/g) and pork (2.8 Log CFU/g) and also the cooked beef (1.5 Log CFU/g), mutton (1.3 Log CFU/g) and pork (1.9 Log CFU/g) samples. A similar trend was observed in the values of Staphylococcus aureus (Staph) and Escherichia coli (E. coli) counts in raw and cooked meat samples. However, a positive correlation between Aerobic plate counts (APC) and Staphylococcus aureus (Staph) (P<0.001) and Escherichia coli (E. coli) (P<0.01) was found in the study. It can, therefore, be concluded that there were no differences in the microbial counts of raw and cooked meat sold in the informal markets of Nkonkobe and Buffalo City Municipalities in the Eastern Cape Province, South Africa.

  • Description: Organisational communication entails the interaction that the management has with its stakeholders. Communication is never complete if the message sent has not been fully understood by the receiver. Hence, for communication to be effective, the sender has to provide two-way open channels of communication as it allows dialogue which stimulates reaching a consensus. Thus, this study was done to find out about the effectiveness of organisational communication in relation to the student-directed communication strategies at University of Fort hare, Alice campus. Data were collected from the participants through four focus groups consisting of ten randomly picked students, and in-depth interviews with five SRC members and five University management staff. A qualitative methodological approach was therefore used in this study for data collection and analysis. Furthermore, the data analysed were categorised into different themes. The findings of this study indicate that the right communication messages and channel must always be used by organisations when communicating with stakeholders. The study also found out that communication will be effective if messages are received as intended by the sender. Conclusively, the study notes that stakeholders should be included in decision making processes in the organisation and that if their needs are also catered for, this will make them to be fully involved in understanding organisational concerns positively.

  • Description: This thesis critically examines the nature and purpose of the MobiSAM partnership, in relation to its value as a model resonating with normative theories on the role of the media in South African democratic society. The MobiSAM project introduces a mobile polling application, designed for citizens to provide real-time, user-generated data on crucial municipal service delivery such as clean water in Grahamstown, Eastern Cape, South Africa. The project has partnered with the local community newspaper, Grocott's Mail, to broadcast this data, with the aim to facilitate citizen participation in public problem solving and support local government accountability in service delivery. Despite pervasive poverty in areas such as the Eastern Cape, mobile penetration in South Africa is near universal. The MobiSAM partnership is an ongoing effort to forge new links between social accountability monitors, new media, traditional media, citizens and local government around public issues in Grahamstown, in line with the development objectives of the post-apartheid South African state. The overall theoretical framework for this thesis is taken from Christians, Glasser, McQuail, Nordenstreng and White's Normative Theories of the Media, which provides an analysis of four roles of the media in a democratic society, that is: the monitorial, the facilitative, the radical and the collaborative roles. Within each of these roles, the stated journalistic approach is explored, that is investigative journalism, public journalism, radical journalism and development journalism. Public journalism is focused on as having the most resonance with the goals of the MobiSAM partnership. The chosen research design is a critical realist case study with the selected methods of thematic document analysis and, primarily, in-depth interviews with key project participants. The research goals were to analyse this primary data against the normative theory on the role of the media in a democratic society, and the 'real world' constraints posed by the project’s specific political and socioeconomic context. The findings conclude by offering certain recommendations and areas for further research, such as the central importance of a dedicated municipal reporter for covering complex public issues. This critical realist case study, drawing on qualitative interviews with both the accountability monitors and the media practitioners, interrogates the philosophical understandings on the role of the media in this new project, towards an empirical model for advancing substantive socio-economic change through media in South Africa.

  • Description: The counting of fuzzy subsets of a finite set is of great interest in both practical and theoretical contexts in Mathematics. We have used some counting techniques such as the principle of Inclusion-Exclusion and the Mõbius Inversion to enumerate the fuzzy subsets of a finite set satisfying different conditions. These two techniques are interdependent with the M¨obius inversion generalizing the principle of Inclusion-Exclusion. The enumeration is carried out each time we redefine new conditions on the set. In this study one of our aims is the recognition and identification of fuzzy subsets with same features, characteristics or conditions. To facilitate such a study, we use some ideas such as the Hamming distance, mid-point between two fuzzy subsets and cardinality of fuzzy subsets. Finally we introduce the fuzzy scanner of elements of a finite set. This is used to identify elements and fuzzy subsets of a set. The scanning process of identification and recognition facilitates the choice of entities with specified properties. We develop a procedure of selection under the fuzzy environment. This allows us a framework to resolve conflicting issues in the market place.

  • Description: Networks of maliciously compromised computers, known as botnets, consisting of thousands of hosts have emerged as a serious threat to Internet security in recent years. These compromised systems, under the control of an operator are used to steal data, distribute malware and spam, launch phishing attacks and in Distributed Denial-of-Service (DDoS) attacks. The operators of these botnets use Command and Control (C2) servers to communicate with the members of the botnet and send commands. The communications channels between the C2 nodes and endpoints have employed numerous detection avoidance mechanisms to prevent the shutdown of the C2 servers. Two prevalent detection avoidance techniques used by current botnets are algorithmically generated domain names and DNS Fast-Flux. The use of these mechanisms can however be observed and used to create distinct signatures that in turn can be used to detect DNS domains being used for C2 operation. This report details research conducted into the implementation of three classes of classification techniques that exploit these signatures in order to accurately detect botnet traffic. The techniques described make use of the traffic from DNS query responses created when members of a botnet try to contact the C2 servers. Traffic observation and categorisation is passive from the perspective of the communicating nodes. The first set of classifiers explored employ frequency analysis to detect the algorithmically generated domain names used by botnets. These were found to have a high degree of accuracy with a low false positive rate. The characteristics of Fast-Flux domains are used in the second set of classifiers. It is shown that using these characteristics Fast-Flux domains can be accurately identified and differentiated from legitimate domains (such as Content Distribution Networks exhibit similar behaviour). The final set of classifiers use spatial autocorrelation to detect Fast-Flux domains based on the geographic distribution of the botnet C2 servers to which the detected domains resolve. It is shown that botnet C2 servers can be detected solely based on their geographic location. This technique is shown to clearly distinguish between malicious and legitimate domains. The implemented classifiers are lightweight and use existing network traffic to detect botnets and thus do not require major architectural changes to the network. The performance impact of implementing classification of DNS traffic is examined and it is shown that the performance impact is at an acceptable level.

  • Description: Alzheimer's disease (AD) is the most common type of dementia characterized by intracellular appearance of neurofibrillary tangles, synaptic and neuronal loss; and extracellular accumulation of amyloid-β (Aβ) peptide in senile plaques. The initial causes leading to AD are unknown, and the available treatments are only effective at slowing the degeneration process. The accumulation of arginine in the brain of Alzheimer patients indicates a possible disruption of enzymes responsible for its metabolism. One such enzyme is neuronal nitric oxide synthase (nNOS) and controlling its activity by interacting with nanoparticles may lead to a delay in the onset of the disease. Neuronal nitric oxide synthase was purified using DEAE-Sephacel ion exchange resulting in 10 % yield, 0.43 fold recovery and specific activity 0.09 U/mg. The enzyme was found to be a dimer with a molecular mass of 150 kDa. Characterisation of the nNOS showed an optimum temperature and pH of 50°C and 7.5 respectively, and it was relatively stable at the optimum conditions (t½ = 100 min). The purity was analysed by SDS-PAGE followed by Western blot. Purified nNOS was challenged with 3-7 nm silver and 4-15 nm gold nanoparticles of between synthesized chemical using AgNO3 and either sodium borohydride or sodium citrate. Results showed that gold nanoparticles are more effective at low concentration (5 μM) than silver nanoparticles due to their size difference. Incubation of different concentration of nanoparticles (5, 15, 25, 50 μM) with the purified nNOS showed an initial decrease of 5% in enzyme activity which over time was restored to 80%. This suggests that different nanoparticles are produced in different sizes and interaction over a given time may result in enzyme association–dissociation mechanism. Inhibition studies showed a strong binding of both nanoparticles with Ki values of 1.4 μM and 0.2 μM for silver and gold, respectively. Both nanoparticles inhibited the activity of nNOS extensively as they bound strongly to the inhibition site on the enzyme and were more in contact with fluorophores nanoparticles. This was confirmed by fluorimetry with binding constants of 0.0084 μM and 0.01092 μM for silver and gold, respectively. Results of this study suggest that silver and gold nanoparticles competitively inhibit nNOS.

  • Description: The study attempts to address, from amongst the key issues in the current debate on economic development: the effect of trade liberalization on poverty. The relationship between trade liberalization and poverty levels is investigated in both the long run and the short run for South Africa. To measure trade liberalization, trade openness is used as the standard index. Foreign Direct Investment (FDI) measures financial openness while taxation is a measure of public intervention in the country. Consumption per capita is a proxy for poverty and Real Gross Domestic Product (RGDP) controlled for economic growth. Applying the Johansen Co-integration Techniques and Error Correction Method, empirical results suggest that trade liberalization has a cumulative effect on poverty reduction in the long-run. Lower poverty level is associated with low taxation and high foreign direct investment, particularly in the short run, in South Africa. Therefore, it is recommended that the government needs to design and pursue active development strategies to benefit from openness. There is also a need to enhance the tax revenues of the state through better collection of revenues, and administrative reforms rather than expenditure cut backs, which can reduce the effectiveness of the public sector. The government needs to strengthen allocation of funds to social sectors so as to bring the issue of poverty reduction to the central stage of economic policy making.

  • Description: Since the emergence of business journalism as a genre within the broad spectrum of news reporting, most of the scholarly works into its development have focused on growth in the western (that is developed) world. This indicates that very limited research has been done in the field of business journalism in the developing economies. Thus there exist gaps in understanding the practice of business journalism in Africa and part of this is rooted in how the practice is defined. This study aims to shed light on the practice of business journalism in this African context. It explores the onset and development of business journalism and its evolution in Africa. The main focus in this case study was to understand the definition of business news in the specific context of the Cameroon Tribune. Individual in-depth interviews were used as the main (primary) data collection method along with observation and cursory reading as complementary (secondary) methods. This study is influenced by the sociology of news production which foregrounds theoretical frames such as news construction and gatekeeping. Findings from this study reveal that business news at the Cameroon Tribune is elitist, essentially defined around personality and, is in the most part, development news. Additional findings indicate that the absence of any editorial guidelines leaves most reporters secondguessing how to please management with socialised values mostly acquired through peer learning. In conclusion, this study advances the necessity for the Africanisation of business news. This would entail reporting financial, economic, consumer, and corporate affairs, from a vocabulary and composition context that unveils much exchange taking place in the lives of many Africans.

  • Description: Following many other central banks around the world, the South African Reserve Bank has adopted inflation targeting as its monetary policy framework. The aim of this is to achieve low levels of inflation in order to attain price stability thereby promoting growth. In South Africa, the chosen band to target is 3%–6%. This has been criticised by many trade unions who are calling for the abandonment of inflation targeting. Despite targeting 3%–6%, it is not known whether this is the optimal inflation range for South Africa. Therefore, the aim of this study is to determine the inflation threshold level for South Africa using quarterly data for the period 1983 to 2010. The first section determines whether or not there is a long-run relationship between inflation and growth using the Johansen cointegration method. Exogeneity tests determine the causality between these variables. Vector error correction models are estimated if cointegration is found. The second part determines the threshold level of inflation using the method of conditional least squares. The inflation level that maximises the R-squared value and minimises the residual sum of squares gives an indication of the threshold level. The third part of the study determines whether or not inflation volatility has a significant impact on growth. The first part established that there is long-run comovement between inflation and growth.The causality is bidirectional with both variables being endogenous.Findings regarding the threshold level show that the current inflation targeting band of 3%–6% may be extended up to 9.5%. In addition, the range of inflation from 5.5% to 6.5% promotes economic growth in South Africa. Finally, the evidence suggests that inflation volatility does not have a significant impact on economic growth and the focus of policy should be directed towards the level of inflation as has been the case.

  • Description: As the global energy crisis continues to have an impact on developing countries such as South Africa, stakeholders form an increasingly significant role especially around the concerns of development and the impact on the environment. Environmental conflicts have risen to the forefront in many areas in South Africa. Environmental conflicts fall under public disputes, which often occur as a result of human needs. This study is an attempt to explore the environmental conflict surrounding the proposed Nuclear Power station at Thyspunt, Oyster Bay in the Eastern Cape. Stakeholders are an integral part of environmental conflicts, and analyzing interests of stakeholders is vital in understanding environmental conflicts. This explorative study, seeks explore and to describe the interests of homeowners who are one of the key stakeholders involved the environmental conflict at Thyspunt, Oyster Bay in the Eastern Cape. The homeowners are represented by the St Francis Residents/ Ratepayers Association. The researcher conducted extensive face-face interviews with these homeowners. The organizations official documents, minutes of their meetings, letters to the media and various publications in which homeowners expressed their feelings were also made use of by the researcher in order to triangulate findings, as well as for data collection methods. The major themes were constructed from the study include: Security, Trust, Power and the various sources thereof, as well as a need for self-actualization based on values, and a final theme of the positive functions of conflict. The challenges facing the homeowners in terms of human security and environmental impact of the nuclear development are highlighted. Further recommendations for a more in-depth study are also made.

  • Description: This is a study of the poetry of Don Maclennan in four chapters. Chapter One explores the poetry's deep involvement with the immediate world, and with the being that encounters it. Chapter Two examines the corpus's mistrust of abstract thought, and its suggestions for alternative ways of intepreting (or at least approaching an interpretation of) our existential situation. Chapter Three deals with Maclennan's writing on the subject of death, while the final chapter looks at the response of the poetry to the fact of death: put simply, this is to learn to love the situation we are in, and to record our thoughts for future generations, thus reaching beyond death to share with others the necessarily unique experience of our one and only life.

  • Description: This dissertation reports on the factors that contributed to the successful entry strategy of 1time Airline, a low cost carrier, into the South African airline industry as well as its competitive strategies within this context. Research interviews were conducted in November 2005 and research material gathered until end January 2006. Key issues include an evaluation of 1time's business model in relation to other low cost entrants as well as against material sourced through interviews with 1time Airline management, employees and consumers of the airline's product. Porter's Generic Strategies and Five Forces model are used as a framework in evaluating the airline. It is found that Nohria, Joyce and Robertson's "4+2 Formula" is effectively implemented at the airline, but that further implementation of Game Theory in terms of alliances should be investigated for continued success and sustainability.

  • Description: This case study examines the introduction of Indigenous Knowledge (IK) in the Consumer Studies curriculum of Further Education and Training (FET). The research is centred on the use of enquiry methodologies involving learners observing parent demonstrations of the making of ‘amarewu’ and other activities centred on the propositional knowledge dealing with fermentation in the Consumer Studies curriculum. The research involved a review of curriculum documents, participant observation of a demonstration of local food practices related to ‘amarewu’ and learner research activities and interviews to review the developing learning interactions. The learning activities were focused on the learners’ researching the cultural and nutritional value of ‘amarewu’ and included an audit of food consumed in the community. What transpired from this study was that working with IK in the curriculum is possible. The inclusion of IK is not only possible but desirable and has exciting possibilities for relevance in contemporary education. The active involvement in parent demonstration engaged the learners in IK in their mother tongue, therefore indigenous knowledge has relevance. The curriculum concepts also enhanced the engagement by giving rise to more relevant knowledge and a respect for cultural matters. Intergenerational capital and subject concepts also enabled learners to engage with local nutritional problems and to come up with practical solutions. This study demonstrates how IK intergenerational capital in combination in combination with curriculum concepts (subject knowledge capital) can enhance relevance and the learners’ real engagement with local health and nutritional problems. Not only did the learners have culturally valued knowledge, but also knowledge that has a practical grasp of the problem and that they could use to engage relevant issues. These two views of knowledge join in learning and can be used to address health issues. I therefore recommend connection of cultural knowledge and conceptual knowledge to strengthen the revitalisation of cultural heritage, thus equalising it to the modern patterns of life and enhancing meaningful curriculum orientation.

  • Description: Anredera cordifolia (Basellaceae), Madeira vine, is a perennial, semi- succulent climber native from Paraguay to southern Brazil and northern Argentina. It has a history of weediness and difficulty of control once established. In South Africa Madeira vine has a wide range and distribution with altitudes ranging from 10-1800m above sea level. Described as a transformer species, its sheer weight is capable of breaking branches off trees, causing the potential collapse of forest canopies. Chemical and mechanical control methods are expensive, labour intensive and may provide only temporary relief. A biological control programme was therefore initiated in 2003. Cf Phenrica sp. 2 (Coleoptera: Chrysomelidae: Alticinae), was field collected from A. cordifolia in Brazil, SSW of Cascavel in the Paraná Province during a survey in November 2003. Eggs are laid in groups of 16 with the average fertility rate being 89%. After going though three larval instars, the larvae pupate in the soil with the adults eclosing after a period of 17 days. The total developmental time for a generation from egg to egg ranges between 7-8 weeks. Biological traits that favour the flea beetle as a possible biological control agent include long-lived adults (up to 5 months) and multiple generations during the summer period. Both adults and larvae feed extensively on leaves and stems and although developmental rates will slow down during the winter period, no indication of a definite diapause was found under the prevailing laboratory conditions. After completing the larval no-choice trials with twenty-six plant species from 14 plant families Phenrica sp. 2 proved to be adequately host specific, as larval development was only supported by 3 Basellaceae species (including the control A. cordifolia) and one Portulacaceae species. All of these are introduced species in South Africa. The only indigenous Basella species could not be tested as it has a very marginal distribution, and because it’s inconspicuous nature, it is seldom seen or collected. Adult multi-choice trials were restricted to species that could sustain larval development to give some indication of the acceptability of these species for adult feeding and oviposition. Although adult feeding was initially concentrated on B. alba, the oviposition preference was clear-cut as females only oviposited on A. cordifolia. In order to quantify the impact of Phenrica sp. 2 on plant biomass and to assess the incidence and intensity of foliar damage, a pair of adults was confined to the host plant, for 2 generations, with different levels of larval densities. The results indicated that the host plant, due to both larval and adult feeding, suffered leaf losses of up to 55%. Anredera cordifolia was however still capable of enlarging the root mass despite suffering huge leaf losses. This would imply that A. cordifolia has an effective re-growth capacity and it will only be vulnerable to attack of the storage organs that enable re-growth, or to repeated attack of other plant parts through which reserves are exhausted. Unfortunately the period of exposure (24 days) was too short to prove that Phenrica sp. 2 impacts on the below ground dry mass, but should the plant be completely defoliated, as was observed in the field, the host plant would be forced to deplete stored resources. Phenrica sp.2 has shown to be very host specific and although A.cordifoia loses its leaves during the winter period in most provinces in South Africa, the adults are long-lived and should be able to survive the leafless periods. Further more the relatively short life cycle, high fecundity and 3 generations per year should theoretically insure a strong population build-up that would improve the chances of establishment in the field. All indications are that Phenrica sp. 2 is an agent well worth considering for the biological control of A. cordifolia.

  • Description: This portfolio discusses various important aspects that affect teacher education. The portfolio has become an important tool for assessment in education. The research component of the masters' course that I attended is reflected in this portfolio. To complete this course several aspects were covered. The educational reform process in the Namibian context requires the use of appropriate resources, an environment conducive to learning, active involvement of the learners and teachers who should have a better understanding of the system adopted. Teacher educators are seen as important in transforming Namibian education in the sense of breaking the cycle of authoritarianism and inequities that existed in schooling prior to independence in 1990, and that still continue to exist in many Namibian schools today. Much effort has been devoted to creating conditions in colleges of education, where future teachers experience the same kind of teaching and learning that is envisioned for schools in the country. To accomplish this a great deal of effort has been devoted to the professional development of teacher educators. This masters' course was initiated to address the shortcomings of teacher education in Namibia. The preparation of teacher educators to be willing and able to prepare teachers in a manner that is consistent with national educational goals has been a neglected element of educational reform in Third World countries (Taylor and Peacock, 1997). Nahas Angula defines teachers as critical agents in creating the reform in relation to several broad principals: access, equity, quality, and democracy. As Ebbutt and Elliot (1998) point out, these principles are defined in very broad terms and provide the opportunity for teachers, teacher educators, and administrators to translate the ideals in particular contexts through practical reflection and deliberation. The Namibian reforms are underpinned by democratic ideals, the intention being to develop broad participation in defining and developing the reform tenets in specific contexts. In Namibia it has been recognized that qualitative changes in classroom practice will only occur when teachers understand them and accept them as their own. It is also recognized that because many teachers have been educated under the authoritarian system of the past, conceptual changes are needed in the minds of the teachers for the reforms to be successful. These include a shift from the belief of teachers as civil servants who are merely to "deliver" a curriculum dictated from above, to one of teachers as reflective professionals who play important roles in interpreting and defining the reforms and in giving meaning to such values as learner-centered and democratic education, continuous assessment, and critical inquiry (Swarts 1998). In the case of Namibia, we have a situation where there is an attempt to fundamentally transform an authoritarian education system that emphasized repetition and rote learning of received knowledge to one where learners are active participants in the learning process and where the curriculum is relevant to and respectful of different cultural traditions and communities. The learner-centered philosophy that guides post-independence educational reforms in Namibia calls for breaking down the authoritarian teacher-student relationships of the past. It encourages teachers to begin instruction by gaining an understanding of their learners' existing knowledge, skills, and understandings and to actively involve them in the learning process toward the goal of preparing citizens for a democratic society. The background above will help the readers to understand the sections covered in this portfolio. In the first part, the portfolio looks at a case study that analyses pre- and post-independence teacher education in Namibia. This study focuses on the Rundu College of Education and investigates the implementation of the Basic Education Teacher Diploma (BETD) Broad Curriculum in relation to the History syllabus. This paper presents information on what led to post-independence teacher education reforms in Namibia and why the reform was necessary. The BETD Broad Curriculum advocates the principles underpinning teacher education reforms in Namibia. The analysis looks at whether the History syllabus applies the principles of teacher education reform in relation to practice in the classroom. This paper addresses the historical background of a History curriculum, which shows the importance of a contextual understanding of the theoretical framework. The second paper looks at the theories underpinning the pre- and post-independence curriculum and the reform process in Namibia, how each theory views knowledge and why a decision was taken to apply them. The third paper is a literature review that links the epistemological ideals of reform to the classroom situation. This paper provides the basis for a small-scale empirical research. The research proposal included in the portfolio emerged from the earlier studies and identifies a key area for investigation within the domain of my particular area of teaching. The identified research problem investigated is presented in the final paper of the portfolio. These research findings can be applied to different situations in different schools. The portfolio is completed by the presentation of a short reflection of the role of the portfolio in this masters' course.
