- Description: Dusky kob Argyrosomus japonicus is a wide-ranging estuarine-dependent Sciaenid and an important fishery species throughout most of its distribution. It is one of South Africa’s most valuable coastal fishery species. High levels of juvenile exploitation in estuaries and ineffective management regulations have led to stock collapse, highlighting the need to better understand the spatial and temporal aspects of estuarine-dependency and multiple habitat use. Habitat connectivity is a critical property of estuarine-associated fishes and it therefore follows that knowledge of this link is fundamental in understanding population dynamics and the nursery role of estuarine and/or marine habitats. While dusky kob occur in both estuaries and nearshore coastal zones, limited information on connectivity among these habitats exists. The aim of this study is to assess the role of estuarine nursery habitats in the life cycle of the dusky kob by examining multiple habitat connectivity and determining the drivers associated with estuarine use. A total of 96 dusky kob (237–1280 mm total length) were tagged with acoustic transmitters in both the estuarine and marine environments of Algoa Bay, Eastern Cape, South Africa between May 2008 and September 2010. Their movements were monitored using a network of automated data-logging acoustic receivers deployed in the Sundays Estuary, seven neighbouring estuarine habitats, two commercial harbours and various sites within Algoa Bay.

- Description: The question of ethnicity has been one of the most topical subjects of study by social scientists. The controversies around this phenomenon seem to have been heated up by the high visibility of mobilized and politicized ethnic groups in most multi-ethnic states. Therefore, the extent to which ethnic nationalities are able to effectively manage the interplay of ethnic differences determines to what extent a multi-ethnic nation develops without crisis. Historically Nigeria has come a long way from multi-ethnic entity with political differences and background to the amalgamation of 1914 till the present structure of thirty-six states. Ethnicity, no doubt has contributed immensely to ethnic conflicts in Nigeria because of long standing revulsion or resentments towards ethnic groups different from one’s own or fear of domination which can as well lead ethnic groups to resort to violence as a means to protect and preserve the existing ethnic groups. Significantly ethnicity in Nigeria, is a product inequality among the various ethnic groups orchestrated by a long period of colonialism; a period which witnessed the ascendancy of three major ethnic groups to the socio-political domination of other ethnic groups and a period when the three major ethnic groups were used as a pedestal for the distribution of socio-political goods, resulting in the inability of other ethnic groups to access these socio-political goods. This situation has continued to impact negatively on the forces of national integration and cohesion in ethnically divided Nigeria. Considering the relationship between ethnicity and development; socio-political exclusion is not only ethically dangerous to development but also economically unproductive. It deprives groups and individuals of the opportunity for the necessary development that can be beneficial to the society. Thus, it is important to develop an integrative socio-political frame-work that explicitly recognizes the participatory role of every ethnic group in governance. Hence, there is a need for the adoption of inclusive governance to manage ethnicity in Nigeria. Notwithstanding, ethnic conflict still persists and an attempt will be made in this study to identify the reasons. Central to socio-political sustainability in Nigeria is a system that should recognize that differences are important to development and encompass notions of equality. Such a system should acknowledge the socio-political and economic power of every ethnic group and promote a system devoid of ethnocentric and exclusionary socio-political and economic policies.

- Description: Eudicella trimeni is reportedly one of the most endangered species of the genus, having been declared virtually extinct until recently. Present research has shown that the species occurs in an area wider than previously known. However, its habitat is disappearing at a fast rate and the Eastern Cape and KwaZulu-Natal populations appear to be sufficiently different from each other to warrant at least subspecies status and further investigation. Third instar larvae of the northern population were collected recently in the Karkloof Nature Reserve, KwaZulu-Natal. They were reared to adulthood under environmentally controlled conditions and are here described.

- Description: The study was conducted in Eastern Cape Province to 1) investigate local people’s knowledge and perceptions on Euryops floribundus and 2) landscape distribution and effect of Euryops floribundus on herbaceous vegetation and soil. A total of 90 households who own livestock were randomly selected from the three communal areas, namely; Tsengiwe, Upper Mnxe and Manzimdaka for household surveys and group discussions. For landscape study, a total of about 5 ha of land were selected at Upper Mnxe communal area. Selection criteria included the presence of E. floribundus and different landscape gradients. A total of four 50mx50 plots were marked along the landscape gradients: Bottom, Middle, and Upper Slope and upland positions. To study the effect of E. floribundus invasion on the herbaceous vegetation and soil, a total of 4 ha communal land was selected in an accessible area which had a largely flat terrain. The area was selected to have adjacent sites with no invasion (< 5% shrub cover), light (5-15% shrub cover), moderate (>15-35) and heavy invasions (>35% shrub cover) of E. floribundus. The average household size in the study area was 6.8± 0.7. All people in the three communal areas unanimously ranked sheep as the most important species for their livelihood, but the ranking of cattle and goat varied among the communal areas. All elder groups agreed that Europs floribundus decreases both the quantity and quality of herbaceous forage as well as livestock production. Moreover, invaded patches create more bare areas which are responsible for the loss of top fertile soils and the formation of rills and gullies. The result showed that the total density of E. floribundus significantly increased from the topland (2301 plants ha-1) moving to the bottomland (4888 plants ha-1). Canopy cover was significantly lowest in the topland (17.9%), but the remaining gradients had similar cover. Grass dry matter yield was higher in the bottomlands and sloppy gradients than the toplands. Soil organic carbon was significantly higher (P<0.05) in the flat than the sloppy terrain. Soils from higher elevations (toplands and upper sloppy) had significantly higher N than the lower elevations (bottomlands and Middle sloppy). The lowest dry matter was observed at low invasion and non-invaded sites. Soil chemical properties were generally different from all density levels. In conclusion, E. floribundus encroachment was found to be major cause of decline in the peoples’ livelihood because as this reduces the vegetation diversity and livestock production, both of which are the major of their livelihoods.

- Description: Euthanasia and assisted suicide is currently illegal in South Africa and amounts to murder. Despite the fact that South Africa has a Constitution, including a Bill of Rights, as well as strong lobbying in favour of the legalization of euthanasia, no legal changes have been effected. Other issues closely intricated with euthanasia, like the so-called “living wills” and palliative care, where an increase of medication can possibly shorten the lifespan of a patient (“double-effect”-medication), are also problematic at the moment. The South African Law Commission has made recommendations regarding the legalization of euthanasia and assisted suicide, as well as the validity of living wills and “double-effect” palliative care practices as far back as 1997, but to present none of the recommendations had been adhered to. The only indication in favour of the toleration of euthanasia and assisted suicide is that the courts have handed down lenient sentences in cases of this nature. In this treatise the legal position in South Africa is compared to that applicable in the Netherlands and in Canada in an attempt to see whether or not South Africa can learn something from these countries as far as the development of its own legal system, relating to euthanasia, is concerned. The Termination of End of Life Decisions and Assisted Suicide Act is applicable in the Netherlands and legalizes euthanasia and assisted suicide subject to strict requirements being complied with. Although euthanasia is illegal in Canada, the courts have recently shown a noteworthy human rights approach that almost resulted in the legal position in the province of British Columbia being changed. It will be submitted that South Africa must take thorough note of these two foreign legal systems, as well as of the recommendations of the South African Law Commission and the Bill of Rights, especially the rights to life, dignity, equality and freedom and security of the person.

- Description: Local government is an important level of participatory democracy, where communities play an active role not only as the electorate, but also as end-users and consumers, and thereby holding their municipal councils accountable for their actions. Given the above statement, the interim Constitution of the Republic of South Sudan 2011, entrusts local government with the provision of services to communities in a sustainable manner. It also provides for the promotion of social and economic development and the promotion of a safe and healthy environment. This also entails the need for a commitment to service delivery hence, public representatives and public officials must take seriously their obligation to render services to the people that could be in the form of ensuring that refuse gets collected, electricity being supplied and other services rendered which better the general welfare of citizens. There are several definitions of public participation, but it can be defined as a process of empowering citizens by involving them in making decisions on all issues that concern them, which can be political, social or economic. The main aim of this study was to, investigate and identify the nature and extent of integrated participatory planning in Yei River County and the extent to which opportunities for public participation are accessible to the communities. The study sought to investigate: How different stakeholders in the community in Yei River County make use of public participation opportunities during the integrated participatory planning process? As such, the main objectives of the study were to; to assess the existing integrated participatory planning practices in Yei River County, to examine and evaluate how the existing integrated participatory planning practices influence service delivery in Yei River County and lastly to identify the barriers to effective integrated participatory planning in YRC and advance recommendations for improvement. Purposive and snowball sampling methods were used and data was collected from a sample of two hundred and twenty-six (226) public officials, comprising of Local Government officials, County councillors and members of the public. Results from the data collected using open and close-ended questionnaires, showed that public participation is very important in local government planning as it leads to incorporation of public suggestions and interests in the development strategies. The results further showed that public meetings and workshops were the only public participation mechanisms being used by Yei River County. The study therefore recommended among other things that, Yei River County should strengthen public participation in integrated participatory planning by providing adequate skilled human resources and establishing structures, as well as public participation mechanisms at the Payam and Boma levels. It was also recommended that the communities needed to utilise all available mechanisms of participation to ensure maximum participation during the integrated participatory planning processes.

- Description: Social media has become one of the defining features of the technological advances known as Web 2.0. As social media has increased in popularity, so businesses are expected to participate. Social media platforms enable businesses to widely broadcast a message as well as interact directly with individual customers. Customers are also able to interact directly with one another and share information and reviews about products and services offered. This suits the tourism industry particularly well. Internationally, research has shown that individuals use social media and other online tools to research potential holiday destinations. In addition social media is used during travel to share snapshots and commentary as well as after travel, through reviews and recommendations on platforms such as TripAdvisor. However, few studies have investigated how tourism destinations use social media to attract new clients and retain existing clients. Very little research has been done on tourism and social media in South Africa despite the importance of this industry to Gross Domestic Product (GDP). This study focused on four-star establishments within the photographic wildlife tourism industry in the Eastern Cape of South Africa. An initial survey of social media participation was carried out within the framework set out by Chan and Guillet (2011); this was then followed up with interviews with selected managers. Results showed that, in general, Private Game Reserves (PGRs) had embraced social media as a communication and marketing platform; despite concerns raised about the lack of control over content as well as poor understanding of the influence social media might have on the bottom line. TripAdvisor, Facebook and Twitter were the most commonly used platforms due to management familiarity with the platform and their ease of use. Few lodges utilised blogs or content sites such as YouTube and management cited time commitments associated with this type of platform as a reason for non-participation. However, although most PGRs or lodges had a profile on social media, this did not always mean active participation. Frequently, lodges began updating but gradually stopped after a few months. It was noted however that only one of the lodges interviewed retained an individual whose sole responsibility was social media; generally lodges did not feel that a dedicated person was necessary. This may result in a lack of time available on the part of the individual responsible or simply be a case of not understanding the platform or how to use it effectively. However, none of the PGRs with poor social media participation responded to interview requests and therefore it was not possible to determine the reasons for their poor participation. Among those lodges that actively participated, most succeed in retaining fans and followers through consistent posting of relevant and interesting content as well as customised responses that encouraged fans or followers’ interaction. However, there did not appear to be any evidence of using social media to learn about fans and followers in order to better customise the lodge offerings. This may not be necessary in this type of industry as PGRs sell a specific product and have a limited ability to customise offerings. In addition, there may be other sources of market information which lodges prefer to use. Special offers, competitions and promotions had limited success on social media. Generally, lodges used social media to promote links to a dedicated competition or promotions page. In conclusion, the managers interviewed felt strongly that social media had made a measureable impact on the tourism industry and was a channel that was here to stay. Further research around the best practice and most effective use will enable PGRs to develop and maintain effective strategies for social media participation.

Internationally, research has shown that individuals use social media and other online tools to research potential holiday destinations. In addition social media is used during travel to share snapshots and commentary as well as after travel, through reviews and recommendations on platforms such as TripAdvisor. However, few studies have investigated how tourism destinations use social media to attract new clients and retain existing clients. Very little research has been done on tourism and social media in South Africa despite the importance of this industry to Gross Domestic Product (GDP). This study focused on four-star establishments within the photographic wildlife tourism industry in the Eastern Cape of South Africa. An initial survey of social media participation was carried out within the framework set out by Chan and Guillet (2011); this was then followed up with interviews with selected managers. Results showed that, in general, Private Game Reserves (PGRs) had embraced social media as a communication and marketing platform; despite concerns raised about the lack of control over content as well as poor understanding of the influence social media might have on the bottom line. TripAdvisor, Facebook and Twitter were the most commonly used platforms due to management familiarity with the platform and their ease of use. Few lodges utilised blogs or content sites such as YouTube and management cited time commitments associated with this type of platform as a reason for non-participation. However, although most PGRs or lodges had a profile on social media, this did not always mean active participation. Frequently, lodges began updating but gradually stopped after a few months. It was noted however that only one of the lodges interviewed retained an individual whose sole responsibility was social media; generally lodges did not feel that a dedicated person was necessary. This may result in a lack of time available on the part of the individual responsible or simply be a case of not understanding the platform or how to use it effectively. However, none of the PGRs with poor social media participation responded to interview requests and therefore it was not possible to determine the reasons for their poor participation. Among those lodges that actively participated, most succeed in retaining fans and followers through consistent posting of relevant and interesting content as well as customised responses that encouraged fans or followers’ interaction. However, there did not appear to be any evidence of using social media to learn about fans and followers in order to better customise the lodge offerings. This may not be necessary in this type of industry as PGRs sell a specific product and have a limited ability to customise offerings. In addition, there may be other sources of market information which lodges prefer to use. Special offers, competitions and promotions had limited success on social media. Generally, lodges used social media to promote links to a dedicated competition or promotions page. In conclusion, the managers interviewed felt strongly that social media had made a measureable impact on the tourism industry and was a channel that was here to stay. Further research around the best practice and most effective use will enable PGRs to develop and maintain effective strategies for social media participation.

- Description: General-purpose computation on graphics processing units (GPGPU) has great potential to accelerate many scientific models and algorithms. However, some problems are considerably more difficult to accelerate than others, and it may be difficult for those new to GPGPU to ascertain the difficulty of accelerating a particular problem. Additionally, problems of different levels of difficulty require varying complexities of optimisations to achieve satisfactory results, and currently there is no clear separation between the different levels of known optimisations, which would be helpful to new users of GPGPU. Through what was learned in the acceleration of three problems, problem attributes have been identified to assist in evaluating the difficulty of accelerating a problem on a GPU. We envisage that with further development, these attributes could form the foundation of a difficulty classification system that could be used to determine whether GPU acceleration is practical for a candidate GPU acceleration problem, aid in identifying appropriate techniques and optimisations, and outline the required GPGPU knowledge.

- Description: In this work the combustion characteristics of coal, charcoal, microalgae biomass and blends between these three components were evaluated by means of non-isothermal thermogravimetry. Blends between coal, charcoal and microalgae biomass were made according to the specifications of a D-optimal mixture design so as to be able to model interactions between the three components with maximum precision despite multiple constraints built into the design. These constraints specified that coal can have a minimum value of 70 mass percent in any blend, while microalgae can have a maximum value of 20 mass percent. While coal and charcoal were blended by mixing the two respective dry components, microalgae biomass was incorporated into the blends by first absorbing microalgae onto fine coal from concentrated slurry of the microalgae in water. The microalgae in these blends were therefore intimately associated with the coal. This approach differed substantially from the normal practice of preparing coal – biomass blends (which are usually dry-mixed as for coal – charcoal blends). Proximate analyses of the starting materials showed that the microalgae biomass has a significantly higher volatile matter: fixed carbon content than both coal and charcoal, which should improve the combustion of these materials by providing a more stable combustion flame. Analyses of the thermogravimetric data obtained showed that coal and charcoal have much simpler combustion profiles than microalgae biomass for which five different thermal events could be observed in the DTG combustion profile. Qualitative kinetic analyses showed that the combustion of coal and charcoal follows first-order kinetics, but for microalgae biomass combustion, the first two combustion stages appear to follow first-order kinetics. The TG and DTG profiles for coal, charcoal, microalgae and blends of these three components were used to derive values for the so-called comprehensive combustion property index (S-value), which provides a combined measure of the ease of ignition, rate of combustion, and burn-out temperature. The S-values so obtained were used as response variable for the construction of a response surface model in the experimental domain investigated. Following statistical validation of the response surface model, the model was used to predict an optimum S-value or a blend that would display optimum combustion behaviour. Two optimum blends were obtained from the optimisation process, one in which only charcoal is added to coal, and one in which only microalgae is added to coal. Adding both charcoal and microalgae produced an antagonistic effect compared to when only one of these are used. Qualitative kinetic analyses of the combustion data of blends indicate that blends of coal and charcoal combust in a manner similar to the individual components (hence following first-order kinetics), but blends of coal and microalgae follow more complex kinetics despite the fact that the combustion profile is visibly more simple compared to the combustion profile for microalgae alone.

- Description: A great deal of taxpayers’ money has gone to a lot of SMME development initiatives. Despite this effort over the past 17 years, South Africa (SA) lags behind other developing countries, in promoting the growth and sustainability of SMMEs. The impact and achievements of government initiatives have fallen disappointingly short of aspiration (Business Development in South Africa. 2009. Occasional paper). Aims and Objectives: •To evaluate and reflect on the OR Tambo District Municipality SMME funding model and establish whether it has made the desired impact. •Determine if funds that have been channelled by the SA government to SMMEs for business expansion, start-ups, grants, and special industry development have yielded quantifiable results and •Assess the private funding institutions in assisting destitute entrepreneurs in the OR Tambo District municipality. Research methodology: The study was conducted using qualitative research and a questionnaire was used as a data collection tool. The researcher was able to get valuable information on stakeholders in the SMME sector. The stakeholders (SMMEs and funders), formed the core research sample. Results: findings suggest that the OR Tambo Municipality has a funding gap and the current funding model both from public and private funders is not effective in developing SMMEs in the municipality. The overwhelming majority of SMMEs agreed that there is a funding gap between funders and enterprises that seek funding in the ORTDM. “Financing gap” terminology, Underhill Corporate Solutions (UCS) (2011:52) defines it as, ‘a sizeable share of economically significant SMEs cannot obtain financing from banks, capital markets or other finance suppliers.’ About 90 percent of the interviewed SMMEs agreed that there is huge funding gap and 10 percent disputed this and said that there is no funding gap; rather, it’s a funding mismatch between the funders and SMMEs which needs to be tackled by all SMMEs stakeholders. The funding model needs to be revamped so it can also be accessible to start-ups, the unemployed, people with less business management experience and limited skills, and to all sectors of the economy. Various recommendations and suggestions for further research are made based on the research findings. Conclusion: The study has shown that the current SMME funding model is not effective and does not assist in developing SMMEs in ORTDM. The research findings depict the funding plight of SMMEs in South Africa; the SMME plight in ORTDM is more real than imaginary. 70 percent of SMMEs expressed less confidence in government SMMEs agencies in terms of assistance. The bigger portion of SMMEs felt that the funds channelled to government agencies were not providing significant assistance in developing SMMEs in ORTDM. Recommendations: The conclusive response from the sample, reflect structural challenges in the current funding model. About 70 percent of funding institution`s officials said “yes”, the low yield on SMME growth is a matter of funding. The funds which were meant to fund SMMEs for one reason or the other do not reach SMMEs which are looking for funding. Hence the funds channelled in the sector in the last 17 years have not yielded the desired results. 40 percent interviewed government officials conceded that there is serious political meddling in funding SMMEs in the whole province and ORTDM could not be an exception to this rule. 80 percent of interviewed SMMEs in ORTDM said funding was their main problem, and the other 20 percent indicated that their problem was not a matter of funding. The public and the private sector must revise the current funding model or devise another funding model that will: •bridge the existing current funding gap, •distribute the SMME allocated budget and achieve maximum efficiency in budget allocation.

- Description: Local government is the most important sphere of government, given the fact that, it is the closest to the people. It always experiences the service delivery protest by the community residents it serves. This is often due to unfulfilled promises concerning the delivery of services. Often the annual performance results are also unsatisfactory as compared to the agreed upon service delivery agreements. National treasury as a distributor of funding to Municipalities often has to request the return of the unused funds at the end of the financial year period. This is the results of poor managing and planning for the resources at the disposal of the Municipalities. There has been a number of transformational processes over the past few years in the manner that municipalities are being managed and run on a day today basis. This research is focused on the system enhancement for Buffalo City Metropolitan Municipality which is situated in the Eastern Cape province of South Africa. Buffalo City Metropolitan Municipality, in particular, has in the 2011 Local government election acquired a metropolitan status, which requires another transformationprocess in the manner it is being managed. At the same time this automatically raises the bar on the service delivery mode and expectations by the communities. The Constitution of the Republic of South Africa, act 108 of 1996 states how Municipalities are to render services to the communities. And therefore pieces of egislation serves as a guide for the processes and systems in the municipalities at large. This research examined the need for an employee performance management system in the Buffalo City Metropolitan Municipality for the 2012 period. In the review of the literature, there was a number of analysis of issues such as organisation culture which plays an important role in the system implementation and success. And it became evident that, there can be no success of any system in an organisation without the thorough evaluation of the organisational culture. The data was sourced through close ended questionnaires which were distributed to 51 respondents that were identified. These were five Directors, five General Managers, 10 Programme Managers from across the institution, 30 staff members from across all directorates and one portfolio councillor from Corporate service directorate.Each respondent was given a period of one week to respond to the questionnaires. The research provides suggested solutions to the current problems in Municipalities in terms of employee performance management within the organisation. The recommendations provided are not conclusive as the circumstances cannot be the same from one municipality to the other. In order to ensure their sustainability within Local Government, there is need for an employee performance management system to evaluate the performance of all the employees. The research findings identified the leadership role in ensuring the introduction and successful implementation of the employee performance management system, in order to address the service delivery challenges faced by the municipalities.

- Description: The study focused on identifying ways in which to improve and increase the quality of training and supply of skilled artisans in the South African construction industry (especially in Gauteng Province) in terms of short and medium term approach. The construction industry is facing a severe skills crisis and this has made it so difficult to recruit competent artisans. This may be as a result of artisans being regarded as the lowest in the hierarchy of construction worker positions. In addition, these artisans warrant less training than those at executive- and managerial levels. This negative attitude towards artisans training has plunged the industry into crisis. Those involved find it difficult to successfully complete projects on time, within budgeted project costs and within the required quality specification due to lack of competent artisans. However, serious attention is required towards enhancing artisan training in the industry. It is imperative and vital to ensure the survival of the industry. The cardinal aim of this research project was to demonstrate a guiding solution towards the skills crisis. Thus, in order to initiate a tremendous change in the skills profile, certain measures are required, e.g. expanding training institutions to local regions; upgrading and aligning facilities in the training institutions to industrial demands and the dissemination of vital information that will ensure the attractiveness of the industry. This will safeguard the construction organisations operating in Gauteng Province. Although the industry is a major player in the economy, there is need for special attention in order to ensure sustainable growth and economic development. The Government, construction industry stakeholders and training institutions personnel should collaborate to salvage the skills crisis by strategically developing programmes (in accordance with industrial requirements) that will benefit prospective learners. The researcher adopted the descriptive- and analytical survey method, which entailed the use of questionnaires and a review of the related literature for gathering relevant data. The methodology used in the research was the quantitative data analysis. The feature findings of the research concluded that the skilled artisans profile is insufficient to meet industry demands. In addition, training institutions and primary- and secondary educational systems are characterized by ninadequacy and incompetency to produce skilled artisans. The situation is exacerbated by the lack of harmonization between the training institutions and the vindustry’s requirements. Furthermore, the majority of the respondents acknowledged that training of their workers is an important aspect to them, but few of these organisations indicated that they make use of formal training institutions such as FET colleges. The recommendation include that all the stakeholders in the construction industry should form collaborations to strategically develop programmes that would upgrade the existing training institutions. This could be done through provision of adequate funds and resources and the dissemination of vital information that is capable to promote the attractiveness of the industry image.

- Description: The challenges of food insecurity and the manner in which it can be addressed is a global concern. Governments throughout the world have strived for means to address global food security either through development of Millennium Development Goals or United Nations protocols. It is a major concern that the South African Government has made it its centre focus to address the challenge of food security. In the Eastern Cape, the Department of Rural Development and Agrarian Reform has embarked on numerous food production programmes in an attempt to address this challenge. It is however noticeable that these attempts somehow did not manage to address their intended purpose. A study of literature with the aim of identifying critical success factors was done. The critical success factors identified and explored were, project management, establishing a clear mission and project objectives, addressing challenges and opportunities of social, environmental and economical sustainability, addressing physiological needs of the beneficiaries, involving the youth and community, role of extension services, training and capacity development, create local partnership and on-going monitoring and evaluation. The factors were then explored through a study of projects from the food production programme in Amahlathi Local Municipality in the Eastern Cape Province. A multiple case study wherein a purposive selection of four food security projects selected from two food security programmes was conducted. A structured questionnaire was used to source the information from all members of the selected projects to evaluate the existence of the critical factors. The main aim was to test whether these factors, if they existed in these projects, contributed to their existence. The findings reveal that none of the identified factors existed in the selected projects and though not proven, the non-existence of these factors has resulted in these projects being in survival mode instead of a sustainable state. A recommendation is made of a further study focusing on a bigger sample wherein these factors could be tested. The study could assist in developing a formal model for the running of these projects successfully.

- Description: The challenges of food insecurity and the manner in which it can be addressed is a global concern. Governments throughout the world have strived for means to address global food security either through development of Millennium Development Goals or United Nations protocols. It is a major concern that the South African Government has made it its centre focus to address the challenge of food security. In the Eastern Cape, the Department of Rural Development and Agrarian Reform has embarked on numerous food production programmes in an attempt to address this challenge. It is however noticeable that these attempts somehow did not manage to address their intended purpose. A study of literature with the aim of identifying critical success factors was done. The critical success factors identified and explored were, project management, establishing a clear mission and project objectives, addressing challenges and opportunities of social, environmental and economical sustainability, addressing physiological needs of the beneficiaries, involving the youth and community, role of extension services, training and capacity development, create local partnership and on-going monitoring and evaluation. The factors were then explored through a study of projects from the food production programme in Amahlathi Local Municipality in the Eastern Cape Province. A multiple case study wherein a purposive selection of four food security projects selected from two food security programmes was conducted. A structured questionnaire was used to source the information from all members of the selected projects to evaluate the existence of the critical factors. The main aim was to test whether these factors, if they existed in these projects, contributed to their existence. The findings reveal that none of the identified factors existed in the selected projects and though not proven, the non-existence of these factors has resulted in these projects being in survival mode instead of a sustainable state. A recommendation is made of a further study focusing on a bigger sample wherein these factors could be tested. The study could assist in developing a formal model for the running of these projects successfully.

- Description: The study sought to evaluate debt management policy implementation towards revenue management in government leased properties of the Eastern Cape Provincial Treasury at the Transkei Development and Reserve Fund. Secondly, the study aimed at developing a tool for assisting policy-makers and officials involved in debt management and revenue collection. In order to address the research problem, a case study involving randomly selected 27 employees from the Eastern Cape Provincial Treasury and housing ward committee members was adopted. Self-administered questionnaires and interviews were the two data collection techniques utilised. All participants were involved in the study during tea and lunch breaks at the workplace; this constituted the employees’ natural environment. Both quantitative and qualitative designs were utilised in analysing data. Descriptive statistical analysis using excel was utilised to summarise the responses, analyse the demographic profiles of participants and their responses. The results were thus presented in the form of bar charts. Responses which could not be analysed using statistics were analysed qualitatively thus the advantages inherent in the two approaches were exploited. The evidence from the study suggests that government operational employees are aware of their roles and responsibilities as they relate to debt management and debt collection policy. The development of debt management policy promotes rental collection, improve property profitability and ensure the maintenance is in place to improve attractiveness of the government properties.

- Description: Even though the post-apartheid democratic government introduced a “social model” approach to address disability, there is still low employment rate of People with Disabilities. Government has enacted different legislation aimed at the inclusion of people with disabilities into the mainstream of society; however, the majority of people with disabilities are unemployed and often denied employment opportunities. The study seeks to evaluate employment of people with disabilities, identify challenges facing the government departments and local municipalities in employing people with disabilities, and to determine what measures can be taken to improve the employment of this group. A purposive sampling was used to select the government departments and the municipalities. A total of seven organisations, participated in the study consisting of four government departments and three local municipalities of the Joe Gabi District. During the interviews, a semi-structured interview guide was used to generate in-depth interpretation from the participants. The data was then analysed using quantitative methods such as graphs and tables and qualitative methods such as data coding through Tech's (1990) framework as described in (Creswell, 2003). The findings of the research revealed that government departments and municipalities still experience challenges in recruiting and providing employment opportunities to people with disabilities. There are a number of factors perceived by participants as challenges to low recruitment and employment of people with disabilities. These include: A lack of clear internal policies and guidelines at district levels of the government departments; Tendency by the government departments and municipalities to use the Employment Equity Plans only as a tool for compliance with legislation; A lack of effective recruitment strategies especially for people with disabilities. The participants also suggested a number of ways to improve employment and recruitment of people with disabilities, which include partnering with relevant organisations that could help in providing work-seekers who are persons with disability, developing effective internal recruitment strategies, HR managers to be trained in disability management and all relevant legislation and finally departments to fund posts specifically for people with disabilities.

Evaluation of eucalyptus citriodora derived p-menthane-3,8-diol-citronellal acetal as a bio-plasticizer for cosmetic application

- Description: Plasticizers are generally added to cosmetic and personal care products to improve the filmforming abilities of the product and increase flexibility of the film formed on the skin or hair surface. For example, plasticizers are present in perfumes to prolong the release of the specific scent, which is the ultimate goal in a good quality perfume. Plasticizers in nail varnishes prevent chipping, improve the aesthetics by adhering to the keratin in the nail which means the coating stays on for much longer, which is the ultimate goal in nail products. Plasticizers improve the gloss, resist chipping and allow quick drying time. Therefore it can be seen that plasticizers play a vital role in personal care products like perfumes and nail varnishes. Certain plasticizers e.g. phthalates, can cause problems associated with human health and can harm the environment. They are easily available and large volumes can be obtained at a low cost. These phthalates, for example, di-butyl phthalate (DBP) have been identified as carcinogenic. Nowadays the occurrence of cancer is rapidly increasing. The plasticizers present in a large number of consumer and personal care products, can possibly be linked to the ever increasing reports of cancer. Therefore a substitute to the traditional phthalate plasticizers must be investigated. The aim of this research is to produce a plasticizer derived from naturally occurring Eucalyptus oil, which can be used to replace the existing plasticizers in cosmetic formulations. Para-menthane-3,8-diol (PMD), occurring naturally in the oil from the tree, Eucalyptus citriodora, forms an acetal with citronellal (PMD, acetal, citronellal all occur naturally in the oil). It has been previously shown that PMD-citronellal acetal will exhibit plasticizing properties similar to conventional plasticizers. The objective was to enhance the formation of the acetal in the Eucalyptus oil by reacting it with excess PMD. An effective synthesis method for the PMD-citronellal acetal enriched oil (~73.8 percent) was determined from optimization experiments. The physical characterisation of the PMD-citronellal acetal enriched oil was done and compared with that of DBP. The acetal-enriched oil had a lower density, slightly higher solubility in water (at 25°C), lower refractive index (Brix percent) and a higher boiling point (350°C) than DBP. The physical characteristics of the Eucalyptus oil source and the acetal-enriched Eucalyptus oil were very similar. This can be expected as the Eucalyptus oil consists of ~84.3 percent Citronellal, ~ 1.3 percent PMD and 2.7 percent PMD-citronellal acetal. In this study the effectiveness of the acetal-enriched Eucalyptus oil (referred to from now on as the bio-plasticizer) was compared to a conventional plasticizer such as di-butyl phthalate (DBP), commonly used in cosmetic products. Two cosmetic formulations were produced: a nail varnish and a perfume formulation. Various tests were performed on these formulations to investigate the plasticizing properties of the bio-plasticizer. The objectives were to determine if the natural plasticizer is as effective as the potentially carcinogenic phthalate plasticizers and can be used as a substitute for the phthalates in personal care products. The results indicate that the bio-plasticizer does behave similarly to di-butyl phthalate, however, the effectiveness of the bio-plasticizer is lower than that of di-butyl phthalate. As the viscosity of the synthesized oil was high, this affected the overall consistency of the products. A more viscous nail varnish and perfume was produced in comparison to the DBP counterpart. The stability of the bio-plasticizer in the cosmetic formulations of nail varnish and perfume was also investigated. The cosmetic products were incubated at 0°C, 25°C and 40°C over a period of two months. Any changes in colour, odour, pH, refractive index, separation and plasticizer peak change in the gas chromatogram trace were recorded. It was determined that the PMD-citronellal acetal-enriched oil was relatively unstable under elevated temperatures and light intensity. Storage under higher temperatures (40°C) tends to increase the acidity. Therefore the bio-plasticizer must be placed in a closed, covered bottle and stored in an environment away from light and elevated temperatures. According to the gas chromatogram peaks, it was clear that both the bio-plasticizer and the DBP were more unstable in the perfume formulation than in the nail polish and were especially sensitive to light when in the perfume. This could possibly be due to the interaction with the fragrance molecule, p-anisaldehyde.

- Description: Mycobacterium tuberculosis and Human Immuno-Deficiency Virus (HIV) have a high prevalence in South Africa. The development and spread of drug resistant tuberculosis is a serious problem which is exacerbated by tuberculosis (TB) co-infection in HIV patients. Traditional medicinal plants like Annona muricata and Artemisia afra are used for respiratory ailments and antiviral therapies respectively. The aim of this study was to evaluate Annona muricata (ethanolic extract) and Artemisia afra (ethanolic and aqueous extracts) for inhibitory activities against M. tuberculosis and HIV. In vitro bioassays for anti-TB activity included: microplate alamar blue assay (MABA), flow cytometry and ρ-iodonitrotetrazolium chloride assays while anti-HIV activity was determined using an HIV-1 reverse transcriptase colorimetric ELISA kit and an HIV-1 integrase colorimetric immunoassay. Cytotoxicity of plant extracts were assessed by the MTT assay on Chang Liver and HepG2 cells. Potential synergistic effects were determined using the basis of Combination Index. Potential interactions of plant extracts with drug metabolic pathways were evaluated with the Glutathione-S-Transferase assay kit as well as the CYP3A4 assay kit. A. muricata ethanolic extract exhibited anti-TB activity with MIC 125 μg/mL. MABA was shown to be the most sensitive and effective method for the detection of anti-TB activity. Artemisia afra aqueous extract showed HIV-1 reverse transcriptase inhibition exhibiting ˃85 percent inhibition at 1 mg/mL while the ethanolic extracts of A. afra and A. muricata showed inhibition of HIV-1 integrase activity at ˃86.8 percent and ˃88.54 percent respectively at concentrations >0.5 - 4 mg/mL. The aqueous extract of A. afra displayed inhibition of HIV-1 integrase ˃52.16 percent at 0.5 mg/mL increasing to 72.89 percent at 4 mg/ml of the extract. A. muricata was cytotoxic at an IC50 of 30 μg/mL and 77 μg/mL on Chang Liver and HepG2 cells respectively, whilst A. afra aqueous and ethanol extracts were not cytotoxic to both cell lines. The ethanolic extract of A. muricata showed both antagonistic and synergistic properties at various IC values, when used in conjunction with rifampicin. A. afra ethanolic extract interrupted GST activity while aqueous extracts of A. afra and A. muricata had a slight effect. All extracts interrupted CYP3A4 activity, however the ethanolic extracts of A. muricata and A. afra showed greater inhibition than the aqueous extract of A. afra. These extracts should be investigated further as they could be an important source of compounds for treatment of M. tuberculosis and HIV respectively.

- Description: South African rangelands in combination with their surrounding homesteads occupy 13% of the entire land surface in South Africa. These rangelands are a source of forage for communal livestock. The rangelands in communal tenure system are degraded due to high human population and livestock numbers. The rangeland of Peddie was never evaluated since the introduction of Nguni Cattle Empowerment Project. Therefore, socio-ecological evaluation was conducted in order to interlink farmer‟s perceptions and scientific data to recommend appropriate rangeland management and restoration programme. Two structured questionnaires consisting of close and open ended questions were used to investigate farmer‟s perceptions on rangeland condition, dynamics, and their causes. Sixty households were randomly selected on the bases of livestock ownership and the membership in Nguni Cattle Project. In each household, any respondent of 20 years or greater, and a key informant of age greater than 40 years were selected. For scientific assessment of range condition, three homogenous vegetation units namely grassland, scattered and dense bushland were demarcated into four 100m x 50m replicates. In each replicate, two 100m transects were laid parallel to each other with 30m equidistant apart. The step point and harvesting method along each transect were employed for herbaceous species composition and biomass production. The point-to-tuft distance was also determined as a proxy for basal cover. Woody density, species composition and tree equivalents were determined in 200m2 belt transects in each HVU replicates. The germination method for soil seed bank evaluation was also employed to find plant species composition and density. The soil nutrients (OC, N, P, K, Na, Ca, Mg, Zn, Cu and Mn) and pH were analysed through solution preparation and observation under photospectrometer to determine functional capacity of the soil of Peddie rangeland. The farmer‟s perceptions comprised of 63% females and 37% males (n = 120) with a mean household of 8 people, 5 adults and 3 children. It was perceived by 93.3% respondents that the rangeland of Peddie have undergone changes over two decades. These changes were perceived by 83% respondents to be accompanied by decline in livestock numbers. Woody encroachment and overgrazing were perceived to be the major attributes of these vegetation changes. The scientific rangeland condition assessment confirmed that these changes were more pronounced as bush density increases. Dense bushland had a significantly high (p<0.05) encroached condition with 6650 trees ha-1 and 4909.5 TE ha-1 beyond the recommended thresholds of 2400 trees ha-1 and 2500 TE ha-1 respectively. Scattered bushland had a fair condition of 1950 trees ha-1 and 1198.1TE ha-1. Themeda triandra as a key species was significantly higher (p<0.05) in grassland (31.1%) than scattered (15.6%) and dense bushland (6.1%). There was a declining trend in biomass production from grassland to dense bushland. The summer biomass production was significantly higher (p<0.05) in grassland than scattered and dense bushland but winter biomass was not significantly different (p>0.05) from all homogenous vegetation units of Peddie rangeland. However, the soil fertility increased with an increase in bush density except organic carbon (OC) which was 1.61% in grassland, 1.46% in scattered and 1.53% in dense bushland respectively. Soil N, K, P, Mg2+ Na+, Ca2+, Cu, Zn, Mn and pH were significantly higher (p<0.05) in dense bushland than grassland and scattered bushland. High soil fertility in dense bushland may be attributed to by abscission of woody plants and litter decomposition. In the soil seed bank, the abundances of forbs were significantly higher than sedges (χ2 = 12, df = 1, p = 0.001) and grasses (χ2 = 8.333, df = 1, p = 0.004) in all homogenous vegetation units while sedges were not significantly different (χ2 = 3, df = 1, p = 0.083) from grasses. The Sorensen‟s index indicated that soil seed bank and extant vegetation were significantly different (p<0.05). Annual and biennial forbs and sedges had high abundances while perennial grasses formed a bulk in above ground vegetation. This provided an insight that a reliance on soil seed bank for restoration of Peddie rangeland would not be advisable because it can result in retrogression. The communal rangeland assessment provided clear qualitative and quantitative data when the combination of indigenous knowledge and scientific assessments was done. The rationale is that conclusions and recommendations of range assessment are relient on the farmer‟s perceptions pertinent to their livestock production systems and their rangeland management objectives. This study has shown that inclusion of communal farmers in policy making can provide better insight because those are the people experiencing the consequences of range degradation.

The point-to-tuft distance was also determined as a proxy for basal cover. Woody density, species composition and tree equivalents were determined in 200m2 belt transects in each HVU replicates. The germination method for soil seed bank evaluation was also employed to find plant species composition and density. The soil nutrients (OC, N, P, K, Na, Ca, Mg, Zn, Cu and Mn) and pH were analysed through solution preparation and observation under photospectrometer to determine functional capacity of the soil of Peddie rangeland. The farmer‟s perceptions comprised of 63% females and 37% males (n = 120) with a mean household of 8 people, 5 adults and 3 children. It was perceived by 93.3% respondents that the rangeland of Peddie have undergone changes over two decades. These changes were perceived by 83% respondents to be accompanied by decline in livestock numbers. Woody encroachment and overgrazing were perceived to be the major attributes of these vegetation changes. The scientific rangeland condition assessment confirmed that these changes were more pronounced as bush density increases. Dense bushland had a significantly high (p<0.05) encroached condition with 6650 trees ha-1 and 4909.5 TE ha-1 beyond the recommended thresholds of 2400 trees ha-1 and 2500 TE ha-1 respectively. Scattered bushland had a fair condition of 1950 trees ha-1 and 1198.1TE ha-1. Themeda triandra as a key species was significantly higher (p<0.05) in grassland (31.1%) than scattered (15.6%) and dense bushland (6.1%). There was a declining trend in biomass production from grassland to dense bushland. The summer biomass production was significantly higher (p<0.05) in grassland than scattered and dense bushland but winter biomass was not significantly different (p>0.05) from all homogenous vegetation units of Peddie rangeland. However, the soil fertility increased with an increase in bush density except organic carbon (OC) which was 1.61% in grassland, 1.46% in scattered and 1.53% in dense bushland respectively. Soil N, K, P, Mg2+ Na+, Ca2+, Cu, Zn, Mn and pH were significantly higher (p<0.05) in dense bushland than grassland and scattered bushland. High soil fertility in dense bushland may be attributed to by abscission of woody plants and litter decomposition. In the soil seed bank, the abundances of forbs were significantly higher than sedges (χ2 = 12, df = 1, p = 0.001) and grasses (χ2 = 8.333, df = 1, p = 0.004) in all homogenous vegetation units while sedges were not significantly different (χ2 = 3, df = 1, p = 0.083) from grasses. The Sorensen‟s index indicated that soil seed bank and extant vegetation were significantly different (p<0.05). Annual and biennial forbs and sedges had high abundances while perennial grasses formed a bulk in above ground vegetation. This provided an insight that a reliance on soil seed bank for restoration of Peddie rangeland would not be advisable because it can result in retrogression. The communal rangeland assessment provided clear qualitative and quantitative data when the combination of indigenous knowledge and scientific assessments was done. The rationale is that conclusions and recommendations of range assessment are relient on the farmer‟s perceptions pertinent to their livestock production systems and their rangeland management objectives. This study has shown that inclusion of communal farmers in policy making can provide better insight because those are the people experiencing the consequences of range degradation.

- Description: According to the Financial Sector (FS) Charter, in August 2002, at the NEDLAC Financial Sector Summit, "the financial sector committed itself to the development of a Black Economic Empowerment (BEE) charter. It made this commitment, noting that: "Despite significant progress since the establishment of a democratic government in 1994, South African society remains characterised by racially based income and social services inequalities. This is not only unjust, but inhibits the country's ability to achieve its full economic potential. BEE is a mechanism aimed at addressing inequalities and mobilising the energies of all South Africans. It will contribute towards sustained economic growth, development and social transformation in South Africa. Inequalities also manifest themselves in the country's financial sector. A positive and proactive response from the sector through the implementation of BEE will further unlock the sector's potential, promote its global competitiveness, and enhance its world class status". Parties of the Financial Sector Charter agreed on the seven pillars below: 1) Human resource management - provide resources to develop skills of black people with the aim of increasing black participation in all levels of management in the sector. 2) Procurement policies - implement a targeted procurement strategy to enhance BEE. 3) Enterprise development - improve the level of support provided to BEE companies in all sectors of the economy. This would be achieved through skills transfer, administration and technical support. 4) Access to financial services - provide affordable financial services to the previously disadvantaged groups and making sure financial services are accessible to these groups. 5) Empowerment financing - work closely with government and government financial institutions to increase resources for empowerment financing. 6) Ownership in the financial sector - 25% of shares in each party of the FS Charter should be owned by black people by 2010. 7) Corporate social investrnent (CSI) - Each financial institution will have to spend 0.5% of their after-tax profit on corporate social investment projects. The projects should be targeted at black groups with a strong focus on transformation. The research evaluates the applicability of Lewin's Force Field Analysis (a change management model) in the implementation of the Financial Sector Charter at Standard Bank of South Africa. It attempts to achieve this by looking at how the Financial Sector Charter is being implemented at Standard Bank. The research looks at three main areas: 1) The "context" of the research problem, by seeking to understand Standard Bank's understanding of the FS Charter, the importance of implementing the FS Charter by the bank, the progress made thus far in the FS Charter implementation and comparison to the BEE scorecards of the other three main bank. 2) The "process", i.e. how the FS Charter is implemented in the bank, the driving and restraining forces of successful implementation of the FS Charter and the lessons learnt. 3) The "outcome" , i.e. benefits of implementing the FS Charter and what could be done to ensure that change management processes are successfully implemented. Personal interviews were used to discover other valuable information which was not available on the bank's published documents, and other related sources such as the Financial Sector Charter document. The sample size for the study was ten Standard Bank employees from different areas of the bank who are either senior managers or directors, in the bank. Internal publications available on the Standard Bank intranet such as the bank's employment equity plans, and the bank's sustainability reports from 2004 to 2011 (Standard Bank, 2004-2011) were analysed for the purpose of the study. The researcher also analysed public documents such as the bank's annual financial reports, bank's equity reports and internal publications on related topics of the research question. Lewin's Forces Field Analysis (FFA) points out that in any environment where change is required; there are both driving and restraining forces that influence the implementation of a change programme. The FFA is a valuable change management tool at trying to transform the behaviour of an individual, and this will lead to transformation of groups and, ultimately the organisation. It also helps to establish the balance between the driving and restraining forces of the change programme. Lewin's (1951) theory put forward the idea that change occurs in three stages: the first stage of change is unfreezing; the second stage is moving and lastly, the third stage is refreezing. In the unfreezing stage, the bank's change management initiatives would need to be directed at giving the individuals a desire and motivation to be ready and open about a planned change initiative. This could be achieved by clearly communicating why change is important, benefits of change and the compelling reasons for change. In moving, the bank would need to give support and confidence to the people affected by change in order to start accepting and buying-in to new perspectives, which enable them to realise that change will improve the current situation. In the refreezing stage, the bank would need to ensure that new patterns of behaviour are reinforced. This will ensure that the changes are applied in everyday business, and this helps create a sense of stability, where those affected by change feel comfortable and confident with the new approach of doing things. The research concludes that managers should recognise the sensitivity around transformation, and should always try to ensure that change management initiatives directed at transformation are unifying, fair and transparent. This should be done to avoid a situation where an employee (or prospective employees) and other stakeholders feel under-appreciated or overlooked because of their gender or race. This demands a carefully crafted and implemented change management programme, whose results will not only unify the bank's employees, but also create a competitive edge for the bank. Lewin's Force Field Analysis (FFA) model is a change management tool that could be used to produce such results.

- Description: The Botswana Community Based Natural Resources Management (CBNRM) programme started in 1989. Its aims were to promote sustainable development through sustainable natural resources management and utilisation to improve rural livelihoods. The country CBNRM programme has recorded mixed outcomes and this has raised questions on the programme performance throughout the country. Since the programme has been recognised as one of the eight main livelihood strategies for rural communities in Botswana, there was a need to evaluate the programme performance and determine the factors that influence it. This thesis therefore evaluated the performance of CBNRM projects along an aridity gradient in Botswana and by so doing answered the two research questions of: (1) What factors influence the performance of CBNRM? And (2) how does aridity influence the performance of CBNRM programmes? Performance was determined in terms of financial benefits generated by CBNRM projects and the projects adherence to the CBNRM principles. Data were collected from seven selected CBNRM projects covering three aridity zones (wet, medium rainfall and dry areas) in the country. Data were also collected from key informants and community based organisations (CBO) project managers. Research findings have indicated differences in the performance of CBNRM projects across the identified three aridity zones. Factors that influenced the performance of CBNRM projects varied among the three aridity zones. These factors included: existence of complimentary rules and regulations for managing CBNRM projects; literacy levels of communities involved in CBNRM; ethnic composition of the project communities; historic and current socio-economic trends within communities; collaboration between CBNRM institutions and other local level institutes; amount of benefits generated through the projects; ability of institutions to resolve outstanding issues in time and type of CBNRM project. Research results also indicated that there was variation in the performance of CBNRM projects across the three aridity zones. Aridity was found to directly influence the performance of CBNRM projects through its influence on the amount of revenues that projects generated.
