- Description: The retention of knowledge workers has become an increasing challenge both locally and internationally. This study focusses on the factors contributing to the retention of knowledge workers at an Industrial Development Zone in the Eastern Cape. The aim of the study was to investigate the factors that would facilitate the retention of knowledge workers in the IDZ. This was explored through the employee value proposition framework which includes affiliation, career development, work content, compensation, company benefits, work-life balance and performance and recognition. The sample consisted of 30 employees from the IDZ from all business units. Three categories of employee levels were selected namely the executive managers, managers and specialists and professionals. Thematic analysis was used to analyse data which was gathered through semi-structured interviews. The literature reviewed explored the various retention strategies used by organisations. From the literature review it is realised that employee retention strategies vary from one organisation to another. In most cases they are very similar. Although this is the case, not all strategies will work for all organisations, each organisation requires preferred and unique strategies for its employees. The findings indicate that the majority of employees were satisfied with the employee value proposition dimensions in the organisation. The exceptional areas of satisfaction were retirement benefits, career development, performance recognition, relationships with colleagues, health benefits, relationships with direct manager or supervisor and relationships generally within the organisation. Areas of dissatisfaction were also raised on long service incentives, autonomy to do work, relationships with other business units and the performance review process. In order to retain employees at the IDZ, it is recommended that the organisation should focus on enhancing long service incentives. It is also recommended that employees should be given greater autonomy to do their work. Relationships with business units also need to be strengthened. Work-life balance of employees and performance review process also need to be revised.

- Description: The increasing popularity of Nigerian video-film, defined as the ‘Nollywood phenomenon’ (Barrot 2008, Haynes 2010, Adesokan 2011), has attracted recent interdisciplinary academic attention, now known as ‘Nollywood Studies’. The aesthetics and ideological approach of Nollywood video-film are often differentiated from those of the long-established and illustrious African Cinema. Films of Africa are, however, generally characterised by seemingly unique forms of the fantastic – an uneasy theme in scholarship on Nollywood. Although Nollywood video-film is commended by some scholars, its representation of the supernatural and the fantastic is often perceived to be demeaning. Considering the complexity of fantastic themes in creative arts of Africa, this study contributes to this field of study by positioning Nollywood as an interventionist artistic practice that subverts the division between art and popular culture. Further, it considers how this positioning could shift our thinking about what constitutes art and creative practice in Africa. The distinctions between art and popular culture have been inherited from particularly Western disciplines. A critical analysis of the fantastic in Nollywood could expand interpretations of the broader uses of new media and appropriation and develop the discourse on contemporary creative practices of Africa and the parameters of the art history discipline. I interrogate the visual language of the video-film medium through a discussion of other forms of artistic media such as photography, video art, and performance art. The fantastic themes, such as ‘magic’, ‘fetishism’ and violence, conveyed through new media open up a field of questions regarding contemporary social-political dynamics. The cultural value of Nollywood video-film is often based on who makes it. As a proletarian product, Nollywood has been underestimated as a ‘low’ form of culture. Its use of appropriated material connotes the complex dialectics that formulate class difference. I consider how a positioning of video-film as a creative practice could be complicated by the fact that it also operates as a theocentric implement that is used by churches to evangelise. Moreover, I examine how ‘epic’ films construct idyllic notions of ‘ethnicity’ based on dialectics of rational/irrational or real/fantastic. Nollywood video-film also creates images of fantastic spaces. In this thesis, I address concepts of space in Nollywood from which fantastic desire is constructed.

- Description: With a declining population of roughly 3000-5000 individuals in Africa, African wild dogs (Lycaon pictus) are one of the most endangered carnivores in the world. As the global human population expands, it is becoming increasingly unlikely that large portions of land will be set aside for conservation, especially in developing countries. Thus, recent wild dog conservation efforts in South Africa have concentrated on establishing a managed metapopulation. A metapopulation is a group of geographically isolated subpopulations of a species that are managed (using supplementation and harvesting) to mimic natural gene flow. The Great Fish River Nature Reserve (GFRNR) in the Eastern Cape Province of South Africa has been identified as a potential reserve to become part of the national wild dog metapopulation. My research aimed to conduct a feasibility assessment of the long-term (~ 25 years) success of a wild dog reintroduction into the GFRNR. This assessment included biological modelling of wild dogs and their expected prey, and determining the potential anthropogenic threats to wild dogs on the private and communal land surrounding the reserve. I used VORTEX population modelling and determined that the GFRNR is likely to have a wild dog carrying capacity of ~22 individuals. Using a 25-year modelling simulation, the most appropriate wild dog reintroduction scenario would be to reintroduce six females and four males initially and supplement the population with one female and two males in years 3, 10, 15 and 23. In addition, the harvesting/removal of one male and one female in years 10 and 20 would be required to ensure 100% population persistence and adequate genetic diversity. Kudu (Tragelaphus strepsiceros) and bushbuck (Tragelaphus scriptus) are expected to be the two most important prey species for reintroduced wild dogs in the GFRNR. Furthermore, wild dogs are likely to prefer the north-western and south-western sectors of the reserve because of the relatively high prey densities in these areas. However, regular monitoring of both the potential prey and the wild dog populations is essential to ensure persistence of the wild dogs and to prevent prey populations decreasing precipitously. Using structured questionnaire interviews (n = 128), I found that while neighbouring land owners and local communities were generally positive about the potential wild dog reintroduction (56 % of all respondents), several threats to wild dogs were identified along the reserve boundary and on the adjoining unprotected land. Some private landowners and members of rural communities around the reserve (34 %) stated that they would kill any wild dogs that dispersed onto their land. In addition, some respondents (8 %) admitted to believing in traditional uses for wild dog products (e.g. fur) which could result in the illegal killing of wild dogs outside of the GFRNR for traditional purposes. Poaching and the presence of unvaccinated domestic dogs on neighbouring land were also identified as being potential threats to a reintroduced wild dog population. However, such anthropogenic threats appear to be localised to the western and southern boundaries of the reserve. Therefore, by implementing preventative measures (such as anti-snare collars, anti-poaching patrols and vaccination against rabies and canine distemper) the likelihood of such threats occurring can be reduced. I conclude that the GFRNR can sustain a population of wild dogs and successfully contribute to South Africa‘s national metapopulation. An additional reserve will benefit the country‘s metapopulation by increasing the number of wild dogs available for translocation, thereby increasing genetic diversity and overall resilience (to environmental change, disease etc.) of South Africa‘s wild dog population. This will contribute towards the future conservation of this endangered species.

- Description: This study identified the media frames that dominate Thisday newspaper's coverage of China's engagement with Nigeria and relate these frames to frame sponsors, who articulate and contest these framings. Frame analysis is applied to a sample of 40 news, feature and opinion articles between the sample period of 1 November 2011 and 31 December 2012. The study analysed media content from Thisday newspapers, drawing on the four dimensions of frames identified by Entman: define problems, diagnose causes, evaluate causal agents and their effects, and recommend treatment (Entman 1993). Using an inductive approach to frame analysis, the study identified two overarching mega frames, contested among the ruling elites who sponsor their views on China in the media, which define China's engagement with Nigeria; partner/role model and predator. The two mega frames mirror the broad characterisation prevalent in the academic literature on China in Africa. The primary partner/role model mega frame constructs China's engagement with Nigeria as a mutually beneficial economic partnership while on the other hand the predator mega frame constructs it as unequal and exploitative. The study identified the activities of frame sponsors who are articulating and promoting their views on China's engagement with Nigeria in the media as primarily responsible for these framings. The study also identified the activities of frame sponsors (ruling and economic elites) was key to the exclusion of ordinary peoples' voices, civic organisations, trade unions and human rights organisation in the text. However, the study also attributes the exclusion of ordinary voices, human rights, democracy and civic engagements in the text to the weakness of Thisday journalism in mediating the framings of China being promoted and articulated by elite frame sponsors. This is, however, symptomatic of the fault lines of journalism practice in Nigeria.

- Description: Artificial Neural Networks (ANNs) have been used in many fields for a variety of applications, and proved to be reliable. They have proved to be one of the most powerful tools in the domain of forecasting and analysis of various time series. The forecasting of TCP/IP network traffic is an important issue receiving growing attention from the computer networks. By improving upon this task, efficient network traffic engineering and anomaly detection tools can be created, resulting in economic gains from better resource management. The use of ANNs requires some critical decisions on the part of the user. These decisions, which are mainly concerned with the determinations of the components of the network structure and the parameters defined for the learning algorithm, can significantly affect the ability of the ANN to generalize, i.e. to have the outputs of the ANN approximate target values given inputs that are not in the training set. This has an impact on the quality of forecasts produced by the ANN. Although there are some discussions in the literature regarding the issues that affect network generalization ability, there is no standard method or approach that is universally accepted to determine the optimum values of these parameters for a particular problem. This research examined the impact a selection of key design features has on the generalization ability of ANNs. We examined how the size and composition of the network architecture, the size of the training samples, the choice of learning algorithm, the training schedule and the size of the learning rate both individually and collectively affect the ability of an ANN to learn the training data and to generalize well to novel data. To investigate this matter, we empirically conducted several experiments in forecasting a real world TCP/IP network traffic time series and the network performance validated using an independent test set. MATLAB version 7.4.0.287’s Neural Network toolbox version 5.0.2 (R2007a) was used for our experiments. The results are found to be promising in terms of ease of design and use of ANNs. Our results indicate that in contrast to Occam’s razor principle for a single hidden layer an increase in number of hidden neurons produces a corresponding increase in generalization ability of ANNs, however larger networks do not always improve the generalization ability of ANNs even though an increase in number of hidden neurons results in a concomitant rise in network generalization. Also, contradicting commonly accepted guidelines, networks trained with a larger representation of the data, exhibit better generalization than networks trained on smaller representations, even though the larger networks have a significantly greater capacity. Furthermore, the results obtained indicate that the learning rate, momentum, training schedule and choice of learning algorithm have as much a significant effect on ANN generalization ability. A number of conclusions were drawn from the results and later used to generate a comprehensive set of guidelines that will facilitate the process of design and use of ANNs in TCP/IP network traffic forecasting. The main contribution of this research lies in the identification of optimal strategies for the use of ANNs in forecasting TCP/IP network traffic trends. Although the information obtained from the tests carried out in this research is specific to the problem considered, it provides users of back-propagation networks with a valuable guide on the behaviour of networks under a wide range of operating conditions. It is important to note that the guidelines accrued from this research are of an assistive and not necessarily restrictive nature to potential ANN modellers.

- Description: Chrysoblephus puniceus is an over-exploited linefish species, endemic to the coastlines off southern Mozambique and eastern South Africa. Over-exploitation and habitat loss are two of the biggest threats to the sustainability of fisheries globally. Assessing the genetic stock structure (a prerequisite for effective management) and predicting climate related range changes will provide a better understanding of these threats to C. puniceus which can be used to improve the sustainability of the fishery. Two hundred and eighty four genetic samples were collected from eight sampling sites between Ponta da Barra in Mozambique and Coffee Bay in South Africa. The mitochondrial control region and ten microsatellite loci were amplified to analyse the stock structure of C. puniceus. The majority of microsatellite and mtDNA pairwise population comparisons were not significant (P > 0.05) although Xai Xai and Inhaca populations had some significant population comparisons for mtDNA (P < 0.05). AMOVA did not explain any significant variation at the between groups hierarchical level for any pre-defined groupings except for a mtDNA grouping which separated out Xai Xai and Inhaca from other sampling sites. SAMOVA, isolation by distance tests, structure analysis, principle component analysis and spatial autocorrelation analysis all indicated a single population of C. puniceus as being most likely. The migrate-n analysis provided evidence of current driven larval transport, with net migration rates influenced by current dynamics.Two hundred and thirty six unique presence points of C. puniceus were correlated with seasonal maximum and minimum temperature data and bathymetry to model the current distribution and predict future distribution changes of the species up until 2030. Eight individual species distribution models were developed and combined into a mean ensemble model using the Biomod2 package. Winter minimum temperature was the most important variable in determining models outputs. Overall the ensemble model was accurate with a true skills statistic score of 0.962. Binary transformed mean ensemble models predicted a northern and southern range contraction of C. puniceus' distribution of 15 percent; by 2030. The mean ensemble probability of occurrence models indicated that C. puniceus' abundance is likely to decrease off the southern Mozambique coastline but remain high off KwaZulu-Natal. The results of the genetic analysis support the theory of external recruitment sustaining the KwaZulu Natal fishery for C. puniceus. While the high genetic diversity and connectivity may make C. puniceus more resilient to disturbances, the loss of 15 percent; distribution and 11 percent; genetic diversity by 2030 will increase the species vulnerability. The decrease in abundance of C. puniceus off southern Mozambique together with current widespread exploitation levels could result in the collapse of the fishery. A single transboundary stock of C. puniceus highlights the need for co-management of the species. A combined stock assessment between South Africa and Mozambique and the development of further Marine Protected Areas off southern Mozambique are suggested as management options to minimise the vulnerability of this species.

The majority of microsatellite and mtDNA pairwise population comparisons were not significant (P > 0.05) although Xai Xai and Inhaca populations had some significant population comparisons for mtDNA (P < 0.05). AMOVA did not explain any significant variation at the between groups hierarchical level for any pre-defined groupings except for a mtDNA grouping which separated out Xai Xai and Inhaca from other sampling sites. SAMOVA, isolation by distance tests, structure analysis, principle component analysis and spatial autocorrelation analysis all indicated a single population of C. puniceus as being most likely. The migrate-n analysis provided evidence of current driven larval transport, with net migration rates influenced by current dynamics.Two hundred and thirty six unique presence points of C. puniceus were correlated with seasonal maximum and minimum temperature data and bathymetry to model the current distribution and predict future distribution changes of the species up until 2030. Eight individual species distribution models were developed and combined into a mean ensemble model using the Biomod2 package. Winter minimum temperature was the most important variable in determining models outputs. Overall the ensemble model was accurate with a true skills statistic score of 0.962. Binary transformed mean ensemble models predicted a northern and southern range contraction of C. puniceus' distribution of 15 percent; by 2030. The mean ensemble probability of occurrence models indicated that C. puniceus' abundance is likely to decrease off the southern Mozambique coastline but remain high off KwaZulu-Natal. The results of the genetic analysis support the theory of external recruitment sustaining the KwaZulu Natal fishery for C. puniceus. While the high genetic diversity and connectivity may make C. puniceus more resilient to disturbances, the loss of 15 percent; distribution and 11 percent; genetic diversity by 2030 will increase the species vulnerability. The decrease in abundance of C. puniceus off southern Mozambique together with current widespread exploitation levels could result in the collapse of the fishery. A single transboundary stock of C. puniceus highlights the need for co-management of the species. A combined stock assessment between South Africa and Mozambique and the development of further Marine Protected Areas off southern Mozambique are suggested as management options to minimise the vulnerability of this species.

- Description: It is currently hypothesised that the chokka squid (Loligo reynaudi) consist of a single stock. This was tested through a spatial comparison of the morphology of this species. Forty three morphometric characters were measured from 1079 chokka squid collected from three regions: the south coast of South Africa, the west coast of South Africa, and southern Angola. While no significant differences were found for the hard body parts, results from discriminant function analyses showed the soft body morphometric characters from each of the three regions differed, with an overall correct classification rate of 100% for males and 99% for females in all three regions. Due to the existing model being used to assess the resource currently being updated it was not feasible to apply this model to the area-disaggregated data from this study. Rather, the CPUE trends and catches from the area-disaggregated data were compared against those of the area-aggregated data, as a first attempt to discern any appreciable differences which would suggest the use of disaggregated data in future assessments. Both the trawl and jig CPUE trends from the area-disaggregated analysis differed only slightly from those of the area-aggregated data. Similarly, the spring and autumn biomass trends for the main spawning area (east of 22°E) followed the same trends as for the full area. It is therefore concluded that there is currently no need to assess the resource on an area-disaggregated basis.

- Description: The Enemy Release Hypothesis (ERH) predicts that when plant species are introduced outside their native range there is a release from natural enemies resulting in the plants becoming problematic invasive alien species (Lake and Leishman 2004; Puliafico et al. 2008). The release from natural enemies may benefit alien plants more than simply reducing herbivory because, according to the Evolution of Increased Competitive Ability (EICA) hypothesis, without pressure from herbivores more resources that were previously allocated to defence can be allocated to reproduction (Blossey and Notzold 1995). Alien invasive plants are therefore expected to have simpler herbivore communities with fewer specialist herbivores (Frenzel and Brandl 2003; Heleno et al. 2008; Heger and Jeschke 2014).

- Description: The role of institutions – economic freedom – is a critical determinant of economic growth, yet the global distribution of economic freedom is skewed. Economic freedom focuses on personal choice, the ability to make voluntary transactions, the freedom to compete and the security of property rights. The SADC is attempting to alleviate poverty and achieve sustainable development and economic growth. This thesis illustrates that economic freedom, in aggregate, and on an individual component basis, drives economic growth. The annual data for the 12 SADC counties from 2000 to 2009 are used to construct a panel data model to conduct the empirical analyses. Cross-sectional effects, as well as time (period) effects, are valid; and thus, a two-way error-component model is estimated. The Hausman test showed the regressors to be endogenous and correlated with the error term. The Pesaran CD test, suitable for dynamic panels, determined that cross-sections are interdependent; and the cross-correlation coefficient indicated a relatively weak, yet substantial, correlation. The LSDV two-way error-component model is re-estimated using the Driscoll and Kraay standard errors and time-demeaned data to correct for cross-sectional dependence. Given the endogeneity between the idiosyncratic disturbance term and the regressors, the presence of heteroskedasticity and serial correlation, as well as the interdependence amongst the cross-sections, the econometric model is then estimated using the two-step system general method of moments with forward orthogonal deviations – instead of differencing. The results meet all the post-estimation diagnostic requirements: the Arellano and Bond test for second-order serial correlation fails to reject the null hypothesis of no autocorrelation; theSargan test for over-identification fails to reject the null hypothesis that the over-identification restrictions are valid, and the difference-in-Hansen test fails to reject the null hypothesis that the instrument subsets are strictly exogenous. The empirical results confirm the a priori expectations. Economic freedom is a positive and significant driver of economic growth. Investment and economic openness are positively related to growth, whereas government debt decreases growth. Government consumption is an insignificant driver of a country’s growth. The Granger causality test confirmed the direction of causality; economic freedom precedes economic growth; and it is possible for the SADC to improve their growth rates by becoming economically freer. The coefficient of adjustment derived from the error-correction model indicates that the dynamic system takes approximately two years to adjust to the long-run structural level. The Koyck Transformation indicates that the relationship between economic freedom and growth is intertemporal, requiring a lag structure. An impulse-response function shows that a permanent, positive ‘shock’ to economic freedom results in an increase in economic growth, although the extent differs for each country, as well as for the different freedom components. The five individual economic freedom components are all highly significant and positive drivers of growth; however, the magnitude of the elasticity parameters varies. The causality amongst the components indicates that bidirectional causality is present. Therefore, improving economic freedom in one area improves economic freedom in another, creating a multiplier effect.

- Description: A widely held view is that export diversification constitutes an important component of export led growth, and poses a major challenge for many developing countries. Given this, the role of export diversification on economic growth warrants a fresh analysis in South Africa. The primary objective of this study is to determine the impact of export diversification on economic growth in South Africa. In this context, the study seeks to establish the relationship between export diversification, export stability and export growth. Initially, the study examines the extent and structure of export diversification in South Africa; it then empirically establishes the link between export diversification, export stability and export growth. Finally, it develops a model and investigates the effects of export diversification on economic growth in South Africa. As an attempt to fulfill the proposed objectives, this study uses quarterly data for the period 1980 to 2012 as well as data for 28 selected groups of commodities to investigate the effects of export diversification on economic growth in South Africa. Measures of export diversification and structural changes in exports in the context of South Africa were discussed. The findings of this study are that the Commodity Specific Cumulative Experience function showed that plots for manufactured commodities are shifted to the right indicating that the commodities are non-traditional in nature whereas, plots for primary commodities are shifted to the left. Results also indicated that South Africa relies more on traditional exports than manufactured exports. Various measures of export instability were used to calculate the export instability index in South Africa. The results of the study reveal that the South African export basket is slightly diversified, and the less diversified or primary commodities are associated with high instability VECM approach was used to allow us to establish the extent of influence of export diversification and other explanatory variables on economic growth. Consistent with other researchers, the study found that export diversification plays significant roles to economic growth in South Africa. A number of diagnostic checks were employed to validate the parameter evaluation of the outcomes achieved by the model. The model passed all the diagnostic checks. On the whole, the results to a larger extent painted a pictured that export diversification is important or drives economic growth in South Africa. Corroborating our findings with work of other scholars, we conclude that our results are complementary.

- Description: Empirical evidence and theoretical propositions suggest that financial development is strongly correlated to private investment because financial development positively affects investments by affecting capital accumulation, altering savings rate or by channelizing savings to various capital producing technologies. This study empirically investigated the impact of financial development on private investment in South Africa using quarterly data for the period 1994/01 to 2011/04. This study assess whether the theoretical and empirical propositions can be supported in South Africa. Cointegration tests using the Johansen approach (1988) were conducted to examine if there is a stable relationship in the level of private investment and financial development in South Africa. As a proxy for financial sector development, credit to private sector as per cent of GDP and stock market development were employed. Other variables that affect investment such as real interest rates and real GDP were also included in the model. Results of the study indicate that stock market development and real GDP have a positive relationship with private investment. Bank credit to the private sector however showed a negative relationship with private investment. A negative relationship was also noted for the relationship between private investment and real interest rates.

- Description: This study examined whether or not financial intermediation can explain the variations in the savings-investment ratio in South Africa during the period 1990 to 2012. The study specifically tests the McKinnon Conduit Effect hypothesis which states that increasing interest rate raises the capacity of financial savings via financial intermediaries based on data from South Africa. Apart from informal graphical test, this study employed formal tests such as the Augmented Dickey-Fuller and Phillips Perron stationarity tests to test the properties of the variables considered, including interest rates, for stationarity. In order to ascertain the long-run and short-run dynamics between its variables, the Johansen co-integration test is utilized, while the Error Correction Mechanism is also employed. Results from the study state that financial assets (a proxy for financial intermediation), income and real interest rate all positively impact the savings-investment ratio. Additionally, short-run analysis results showed that income, financial assets and real interest rates positively influence the savings-investment ratio. Real interest rates were seen as being both positive and statistically significant. Therefore the study recommended that the financial services sector and the South African Reserve Bank (SARB) should work together as this will result in the improvement of efficiencies in price discovery with regards to bank charges, access to banking facilities and the timely provision of services in order to encourage savings (for investment purposes) in the South African economy.

- Description: The study was about the impact of income generating projects on poverty alleviation and was conducted on Ibuyambo Secondary Cooperative Ltd at Emalahleni Local Municipality within Chris Hani District Municipality in the Eastern Cape. Ibuyambo Secondary Cooperative Ltd consisted of seven primary cooperatives from which data was collected from 18 respondents through questionnaires. To complement that, interviews were conducted with six key informants from government departments and other development stakeholders in the same area. The study was conducted in August 2013. The study covered a literature review on poverty as one variable, with focus on its definition; theoretical perspectives of poverty; poverty in development thought; global statistics on poverty; historical background of poverty in South Africa; structural adjustment programmes as a major cause of poverty; and causes of poverty in sub-Saharan Africa. A literature review of income generation as another variable was also undertaken, with emphasis on definitions; the experience of income generation projects/activities (IGPs/IGAs); key factors for the successful implementation and management of projects; income generation projects and sustainable livelihoods; income generation and poverty alleviation programmes in South Africa; as well as a case study of projects under IRDP in India. The results of the study indicated that Ibuyambo Secondary Cooperative Ltd was generating income. However due to poor governance, mismanagement of funds and theft it was running at a loss and was struggling to finance its working capital and other member benefits. As such it was not making a meaningful impact on alleviating poverty on its members. The study also gave recommendations on the findings.

- Description: This study sought to explore and explain the impact of labour laws on small firms, focusing on employer perceptions of the Labour Relations Act of 1995 and the Basic Conditions of Employment Act of 1997 in three towns of the Eastern Cape. It is important to focus on this impact of labour laws on these firms because of the high unemployment that faces the country. In this regard, it must be emphasised, firstly, that small firms are central to job creation; therefore, they contribute to a reduction in the unemployment rate; hence, the strategies created by the government to reduce any burdens (including regulatory burdens) on small firms. It is therefore important to study the impact of labour law on small businesses in order to assess the regulatory burden on small firms. The theoretical framework which underpins this study on the impact of labour law on small firms arises from the neo-corporatist critique of neo-liberalism. The two frameworks maintain the extent to which the government should intervene in the industrial relations system. Liberalism maintains that there should be a minimum role of the government, which involves only the facilitation of a framework for negotiations between employers and employees. Corporatism, however, maintains a social democratic approach, and holds that there should be an active role of the government in the industrial relations system with business, labour and the state working co-operatively (Klerck, 2009). This theoretical framework therefore shapes the extent to which employers perceive labour laws or state’s regulatory role impacts small businesses. The data was collected through the qualitative inquiry; using face-to-face, semi-structured interviews. The findings in this study included negative employer perceptions of labour laws. More specifically, many of the employers that were interviewed claimed that labour laws were burdensome on their businesses. They claimed that labour laws imposed financial and administrative costs to their firms, negatively affected the employer-employee relationships in these firms as well as the employing decisions of the employers. As a result, the employers saw labour laws as undermining flexibility and imposing unfair rigidities on small firms. Furthermore, employers perceived South African labour laws as not addressing the unique iii circumstances of small firms. They maintained that labour laws treated small firms similarly to large firms. Even though the employers held these perceptions of labour laws, it was evident that these subjective perceptions did not reflect the objective impact of labour laws on small firms. This was firstly related to the fact that many of the employers that were interviewed had negative views of labour laws but these views were not substantiated by particular events in their firms. Secondly, it was revealed that the employers’ perceptions of labour laws were based on their misconception or misunderstanding of labour law. Thirdly, it was revealed in this thesis that small firms were not affected in the same way to big firms by labour regulation. This was related to the fact that many of the small firms’ employers that were interviewed tended to be less concerned by regulation. Specifically, although many employers that were interviewed claimed that labour laws were burdensome on their firms it was evident that regulation was avoided because of the informality that characterised these firms. Consequently informality mediated the impact of labour laws on these firms, and labour laws imposed less ‘costs’ on these firms. However, it cannot be argued that small firms are isolated from the sphere of labour laws. Rather, although these firms were governed by regulation it was found that the extent to which employers complied with regulation depended on the extent to which organisational practice already reflected similarity with the legislative objective. , Acrobat PDFMaker 10.1 for Word , Adobe PDF Library 10.0

- Description: The broad objective of the study is to investigate the impact of Land and Agrarian reforms on poverty alleviation in Joubertina. Purposive sampling method (non-probability sampling) was carried out mainly on two groups of people, land reform beneficiary in Jay Dee Rovon and non-beneficiary in Mon Desire. Moreover, the stratified random sampling method was also applied in Jay Dee Rovon to choose a sample of 60 households from 129 land reform beneficiaries in Jay Dee Rovon and simple random sample of 60 applied to Mon Desire household subsistence. Binary Logistic Regression model was used to test factors that influenced beneficiary on level of production. Results indicated that age and farming experience were significant variables. Age had a negative coefficient value, meaning an increase in age was less likely to cause beneficiary to produce at commercial level. Descriptive statistics revealed that farming activities in the study areas seems to be performed mostly by relatively medium age people followed by younger people and lastly by the older people. Moreover, farming experience with positive coefficient revealed that it is highly likely to influence the beneficiary to produce at commercial for marketing. The older the farmer the more the experience s/he had in farming activities. However, descriptive revealed, medium and young age people with little knowledge tend to be more active than older people on farming activities but on the other hand they are more capable of carrying out physical activities. The results revealed that land reform beneficiaries likely to influence the level of production for marketing while non-beneficiaries produce for home consumption and little for sale in local market. An improvement on yield results an increase on income and thus leading to a change in ownership of household’s durable assets. An increase in yield also indirectly results employment recreation, increasing real wage and improve farm income thus leading to poverty reduction in JDR as compare to MD. The study recommends that the government should also assist non-beneficiaries in MD with agricultural infrastructure to improve their level of production and food security at household level.

- Description: Ongoing instability in the nursing workforce is raising questions globally about the issue of nurse turnover. It is against this background that this research examines the impact of learning, advancement and quality of work-life on turnover intentions among nurses in selected hospitals from Eastern Cape. Little research has been conducted to investigate the impact of the above mentioned subjects on turnover intentions among nurses in the South African health sector. Research questions as well as hypotheses were formulated as the means to gain data on the subject. The research employed a quantitative design with a sample size of 160 nurses and 159 were returned. The data analysis consisted of both descriptive and inferential statistics. The main findings of the study showed a positive relationship among job satisfaction, work-life rewards, learning and advancement opportunities and job satisfaction. However, there were negative relationships between job satisfaction and turnover intentions; work-life rewards and turnover intentions; and also among learning, career advancement and turnover intentions. Finally, suggestions were made to the top management in the Health sector to come up with strategies and mechanisms that improve nurses’ quality of work-life and offering them training and advancement opportunities through organisational change programs.
