- Description: Background and Aim: Microalgae are a potential economical source of omega-3 fatty acids, which are known for their health benefits. Omega-3 fatty acids derived from microalgae are however still expensive due to high costs involved in production. These costs can partly be attributed to cultivation of microalgae in unialgal cultures, which are prone to contamination, difficult to scale up and require stringent control of growth conditions. This study therefore is aimed to investigate the feasibility of using a mixed microalgae culture for the production of omega-3 fatty acids. Methods and materials: The microalgae were grown under uncontrolled conditions in a hanging-bag photo-bioreactor, with only the phosphorus-nitrogen ratio (P:N-ratio) varied. Variations in the different population proportions in the culture were studied and related to the biomass, total fatty acid and omega-3 fatty acid productivity of the culture. Finally, a comparison was made between the results obtained in this study and similar studies found in literature. Results and discussion: The mixed culture used was composed of several green microalgae, whose proportions varied with P:N-ratio, season, and age of the culture. Different interactions between the populations were observable, and these were thought to influence the culture’s biomass, total fatty acids (TFAs) and omega-3 fatty acid productivity. The TFA content of the culture was ~10-20% by the end of the exponential phase, depending on the nutrients supplied. The fatty acids were composed of mostly unsaturated fatty acids, the majority of which were omega-3 fatty acids; C18:3ω3 (up to 50% of TFA), C16:4ω3 (up to 15%) and C18:4ω3 (up to 5%). Other fatty acids observed included C16:0 (up to 25%), C18:1ω9/C18:1ω8 (up to 20%), C18:2ω6 (up to 5%), traces of C18:0, C18:3ω6, C17:0, C16:3ω3 and C16:1ω7 were also detected. The presence of these fatty acids was found to vary depending on season, P:N-ratio, and age of the culture. When compared to studies in the literature, the mixed culture was found to perform better than, or as well as reported studies, where unialgal cultures were cultivated under controlled laboratory conditions. Conclusion: In view of the reported advantages of cultivating mixed cultures, the production of omega-3 fatty acids via such cultures appears attractive. More research however is needed to optimise the culture; study interactions between the organisms and their effect on biomass, total fatty acid and omega-3 fatty acid productivity. Finally, the economic implications of using mixed cultures need to be evaluated as well.

- Description: The use of indigenous knowledge (IK) and indigenous bio-resources by pharmaceutical and herbal industries has led to concerns about the need to protect IK in order to prevent biopiracy and the misappropriation of indigenous knowledge and resources. While some commentators believe that intellectual property rights (IPR) law can effectively protect IK, others are more sceptical. In order to contribute to the growing debate on this issue, this study uses the relatively new and as yet largely critically unanalysed Masakhane Pelargonium case to address the question of whether or not IPR law can be used to effectively protect IK. It is argued here that discussion about the protection of IK is a matter that must be located within broader discussions about North-South relations and the continued struggle for economic and political freedom by indigenous people and their states. The Masakhane case suggests that IPR law in its current form cannot provide sufficient protection of IK on its own. Incompatibilities between IPR law and IK necessitate that certain factors, most important of which are land, organised representation, and what are referred as 'confidence and network resources', be present in order for IPR law to be used with any degree of success. The study also reveals various factors that undermine the possibility of using IPR law to protect IK. In particular, the study highlights the way in which local political tensions can undermine the ability of communities to effectively use IPR law to protect their knowledge. The thesis concludes with several recommendations that will enable indigenous communities and their states to benefit more substantially from the commercialisation of their bio-resources and associated IK.

- Description: Integrated Quality Management System (IQMS) consists of three policies, namely; the Developmental Appraisal System; Whole School Evaluation and Performance Management System, designed to foster a culture of continuous improvement in schools. However research has cast doubt on the integration of the three policies. It has been argued that the implementation of the three policies is fragmented, with diverse goals, multiple purposes, values that are at variance, and conflicting expectations, causing tension between personal needs and improvement needs. The aim of this study is to understand how IQMS practices and systems promote continuous improvement. This was a case study of four primary schools located in different contexts in East London District. In-depth interviews were conducted on a total of 12 participants across all the schools. There were three main findings. First, IQMS is understood and practised as an external intervention. It appears not to have been internalised as a quality management system. Second, the participants were ambivalent about the IQMS practices as enablers and as barriers of continuous improvement. A fair amount of educators did not view IQMS as daunting as some had portrayed it. Third, There were blurred lines between what participants recognised as systems and the actual practices in the implementation of the three IQMS policies . There was no evidence of systemic thinking on the part of practitioners. As far as the IQMS systems and practices are concerned, no direct mention of evaluation variables or paradigms can be found, making it somehow complex for educators to distinguish between identifiable systems and practices. Finally, the external and internal quality assurance practices seemed to have been subsumed under managerial imperatives of compliance and accountability. Educators revealed that they merely undertake the process as they are compelled to do so as an expectation or requirement by the Department of Education. Given the above findings it can be concluded that and if continuous improvement is to be achieved through the IQMS strategy, there is a need to re-invent it such that , embedded in its systems and structures is a culture of continuous improvement. The reconfiguration of IQMS should look for mechanisms for integrating the three policies. The study recommends, for practice there should be a balance between professional development of educators and managerial imperatives that demand compliance and accountability. Further study must be undertaken to unravel the three IQMS policies.

- Description: This psychobiography is focused on the life of Glenda Watson-Kahlenberg, whose life history epitomises the redemptive theme of triumph over tragedy. A phenomenological approach to the study allowed the researcher to observe the participant‟s lived experience through the theoretical lens of Frankl‟s conceptualization of a meaningful and full existence. A holistic perspective of factors contributing to redemption was accommodated by the Biopsychosocial-spiritual Model. The aim of this longitudinal revelatory study was to illuminate the process of redemption in a life, which leads to restoration and wholeness. This study breaks with traditional psychobiography – in that a life in progress has been selected; and personality development is not the key focus. This psychobiographical undertaking was anchored in qualitative research in the form of a single case study. Four types of triangulation were utilized, namely: data, investigators, theory and methodological triangulation. In addition, Alexander‟s identifiers of saliency, Miles and Huberman‟s data-management guidelines, Schultz‟s prototypical scenes, and Guba‟s criteria for trustworthiness, guided the methodology to ensure reliable data extraction and interpretation. The present researcher was in search of a deeper understanding of the enabling factors facilitating a restorative process in a life that was challenged by setbacks. Given the increasing pressures facing individuals in this modern era, the redemptive theme holds particular relevance, and was graphically demonstrated in the life of the participant who experienced trauma, widowhood, divorce, single parenthood, and a spate of medical and psychological setbacks. The findings suggest that the mental health clinician‟s utilisation of Frankl‟s conceptualisation of meaning in the most challenging circumstances, proffers itself as an all-purpose life-tool which enables individuals to overcome their challenges. The study demonstrated that gaining meaning in life is inextricably tied to an implicit legacy-oriented worldview. Of significance, is the role of forgiveness which emerged as the central redemptive catalyst. In this study, the resolution of past hurts through forgiveness, and the search for meaning, merge, forming an arterial theme in the life story of the participant. The dual impact of these factors not only reversed contaminated life-scripts, it also birthed a new calling in life which set the participant on a generative life course. The findings related to a redemptive life not only confirms existing theory, but also adds perspectives not previously considered. In addition, the findings related to the role of forgiveness has positive implications for the individual‟s physical and psychological wellbeing. Greater intentionality on the part of therapists to thread forgiveness into their practice, remains invitational in the light of the eugraphic impact demonstrated in this study.

- Description: Public service delivery is a major challenge to governments in both the developing and developed worlds. Governments have used various strategies to enhance service delivery. These strategies have resulted in varying outcomes and levels of service delivery. In the Kenyan government, the strategies to enhance service delivery include: Results Based Management strategies, service charters, Information Communication Technology (ICT), performance contracting, and strategic plans. This study is an investigation of reforms in the Ministry of Immigration and Registration of Persons (MIRP), Kenya. The study sought to investigate the effects of Results Based Management on service delivery; to investigate the effect of strategic planning on service delivery in Kenya; to investigate the effect of ICT on service delivery in Kenya; and to investigate the effect of Business Process Re-engineering (BPR) in service delivery. This study utilized a descriptive research design where the researcher investigated and collected factual data to describe the situation or problem. Secondary data was sourced from document reviews. Data was analyzed as it was collected. The researcher classified the data in terms of the topic, themes and content. The broad topic and themes of the data collected was based on the research objectives of this study and included: use of Information Communication Technology, Business Process Re-engineering, Results Based Management, and strategic planning. The findings revealed that the department has utilized Results Based Management, strategic planning, Information Communication Technology, as well as Business Process Re-engineering tools in reforming public service delivery towards effectiveness and efficiency. Furthermore, this study also revealed that the department has accrued various benefits as a consequence of these tools despite the challenges facing their implementation. According to the report, the reform programs have enhanced greater transparency in service delivery, improved accountability, responsibility in employees, enhanced policy coherence and strengthened capacity. these advantages are evident to the Department of Immigration. the study recommends that the use of Results Based Management, ICT and Business Process Re-engineering policies and changes should be implemented to improve service delivery in the Ministry of Immigration and Registration of Persons. In addition, the study recommends the following further studies: the study should be replicated to other public organizations (agencies) to allow for comparison of the findings of this study; the study recommends research on the success of public organizations in achieving objectives of their strategic planning (this is based on the challenges identified facing strategic planning in the Department of Immigration); and, finally, this study recommends future research on the relationship between Business Process Re-engineering (BPR) and efficient service delivery. This study will provide insight to what extent BPR affects service delivery.

- Description: This is a quantitative study which explores whether there is a positive relationship between customer satisfaction as perceived by corporate customers and revenue generated from such customers of the corporate division of a single South African bank. This research report has three sections, namely the (1) academic paper which comprises a condensed literature review, research methods, results and discussion, (2) an expanded literature review, and (3) an expanded research methodology. Although these three sections are interrelated, they may be considered stand-alone documents. A review of literature contends that customer satisfaction has been a topic of interest for over four decades when, in 1965, the concept was first introduced to literature by Cardozo. Even in these early stages it was hypothesized that higher customer satisfaction would lead to repeat purchasing and cross selling. Thus, for some time, researchers have proposed that a link exists between customer satisfaction and a company’s bottom line, ultimately alluding to the notion of positive associations between customer satisfaction, revenue and profitability. The corporate banking division of a South African bank has dedicated significant time and economic resources to monitoring and improving the satisfaction of their corporate customers each year. With a focus on this single corporate banking division, this quantitative study used secondary customer satisfaction data to establish whether a positive relationship between customer satisfaction with a bank representative or more formally termed, the ‘transactional banker’ (TB) and revenue at an account level exists. The study used a one-dimensional customer satisfaction construct summated from several variables or a one-dimensional multi item scale. This quantitative study made use of secondary data obtained through customer satisfaction surveys conducted with the division’s clients in three waves during September 2010, March 2011 and September 2011. At the time of data collection, telephone interviews were conducted with individuals in corporations who were customers of the corporate division within the bank. These individuals in their respective corporations were identified and surveyed because they (a) managed the primary relationship of the corporation with the banking division and (b) were senior financial decision makers of their organization’s (i.e. had the ability to influence a decision to change banks). Sample sizes of 273 (September 2010), 259 (March 2011) and 310 (September 2011) individual corporate customers were achieved through a method of stratified sampling. In this study, customers were stratified according to the TB who is responsible for their account. Within each stratum a random sample of 10 – 15 participants were included for each of the 30 TB’s. Monthly revenue data, recorded as a) credit revenue, b) overdraft revenue and c) total revenue was sourced from internal company records for each month from September 2010 to January 2012. Pearson’s correlation coefficient was used to assess whether a positive correlation between the two variables of customer satisfaction and revenue exists. This was followed by Ordinary Least Square Regression to investigate the magnitude and nature of the relationship between customer satisfaction and revenue using customer satisfaction as the independent variable and revenue as the response variable. Cronbach’s alpha was also used for internal scale validity. The results of the research indicated no statistically significant relationship between a customer’s satisfaction with the performance of their TB and either the credit, overdraft or total revenue generated from such a customer through their account. By highlighting this, these findings, nevertheless, contribute to the growing body of knowledge examining the impact of customer satisfaction efforts on revenue. On the basis of the findings of this study, it cannot be practically recommended that customer satisfaction efforts be terminated or changed within the organization of study owing to several study limitations which were present. Firstly, the study was hampered by small sample sizes due to a lack of the availability of revenue data in some instances, particularly in the case of overdraft revenue. Secondly, the study only focused on a single bank account held with the bank and increases and decreases in revenue based on the balances held within that single account. Since one of the purported consequences of improved customer satisfaction is the purchase of additional products, the current design of the study does not take into account the take up of additional accounts or banking products with the bank. Thus, an increase in revenue for the bank as a whole due to the purchase of additional accounts may be masked. Similarly, the scope of the study does not extend to examining the effect of recommendations made by these corporate customers to others and hence growth of divisional or bank revenue due to the addition of new customers. Finally, this quantitative study does not examine revenue growth when compared to customer satisfaction improvements over time due to a limited sample of customers taking part in the study over a number of periods as well as incomplete revenue data. The recommendations for future research are to examine the relationship between changes in customer satisfaction and changes in revenue at divisional level in the long run within the South African banking industry as the impact of an increase in customer satisfaction may be obscured by salient factors in the short run. It is also suggested that future research look at the correlation between dissatisfaction and revenue, where adequate sample sizes are available. Theoretically, the results of this research do bring into serious question the universal application, especially in the context of the South African banking industry of the Service Profit Chain and Satisfaction Profit Chain which propagate the existence of a positive relationship between customer satisfaction and revenue.

These individuals in their respective corporations were identified and surveyed because they (a) managed the primary relationship of the corporation with the banking division and (b) were senior financial decision makers of their organization’s (i.e. had the ability to influence a decision to change banks). Sample sizes of 273 (September 2010), 259 (March 2011) and 310 (September 2011) individual corporate customers were achieved through a method of stratified sampling. In this study, customers were stratified according to the TB who is responsible for their account. Within each stratum a random sample of 10 – 15 participants were included for each of the 30 TB’s. Monthly revenue data, recorded as a) credit revenue, b) overdraft revenue and c) total revenue was sourced from internal company records for each month from September 2010 to January 2012. Pearson’s correlation coefficient was used to assess whether a positive correlation between the two variables of customer satisfaction and revenue exists. This was followed by Ordinary Least Square Regression to investigate the magnitude and nature of the relationship between customer satisfaction and revenue using customer satisfaction as the independent variable and revenue as the response variable. Cronbach’s alpha was also used for internal scale validity. The results of the research indicated no statistically significant relationship between a customer’s satisfaction with the performance of their TB and either the credit, overdraft or total revenue generated from such a customer through their account. By highlighting this, these findings, nevertheless, contribute to the growing body of knowledge examining the impact of customer satisfaction efforts on revenue. On the basis of the findings of this study, it cannot be practically recommended that customer satisfaction efforts be terminated or changed within the organization of study owing to several study limitations which were present. Firstly, the study was hampered by small sample sizes due to a lack of the availability of revenue data in some instances, particularly in the case of overdraft revenue. Secondly, the study only focused on a single bank account held with the bank and increases and decreases in revenue based on the balances held within that single account. Since one of the purported consequences of improved customer satisfaction is the purchase of additional products, the current design of the study does not take into account the take up of additional accounts or banking products with the bank. Thus, an increase in revenue for the bank as a whole due to the purchase of additional accounts may be masked. Similarly, the scope of the study does not extend to examining the effect of recommendations made by these corporate customers to others and hence growth of divisional or bank revenue due to the addition of new customers. Finally, this quantitative study does not examine revenue growth when compared to customer satisfaction improvements over time due to a limited sample of customers taking part in the study over a number of periods as well as incomplete revenue data. The recommendations for future research are to examine the relationship between changes in customer satisfaction and changes in revenue at divisional level in the long run within the South African banking industry as the impact of an increase in customer satisfaction may be obscured by salient factors in the short run. It is also suggested that future research look at the correlation between dissatisfaction and revenue, where adequate sample sizes are available. Theoretically, the results of this research do bring into serious question the universal application, especially in the context of the South African banking industry of the Service Profit Chain and Satisfaction Profit Chain which propagate the existence of a positive relationship between customer satisfaction and revenue.

- Description: The economic boom in South Africa following the 1994 democratisation led to increased welfare of the citizens and their purchasing power. This further resulted in increase in electricity consumption. The electricity supply did not increase proportionally to the increase in electricity consumption leading to the 2008 shortage of electricity which nearly damaged the power generating circuit. The literature review has shown that electricity supply and consumption have a positive impact on economic growth. It further showed that employment enhances economic growth. Conversely, it showed that power outages negatively affect economic growth. The research serves to investigate the relationship between electricity supply and economic growth in South Africa and to examine the impact of power outages on economic growth. It also seeks to find the appropriate structure for electricity supply industry that will lead to increase in economic growth. The autoregressive distributed lag (ARDL) bounds approach was used to find the relationship between economic growth, electricity supply, power outages and employment using quarterly data from 2000 to 2012. The ARDL technique was chosen over the conventional models such as Johansen technique for the research because it uses a single reduced form of equation to examine the long run relationship of the variables as opposed to the conventional Johansen test that employs a system of equations. The ARDL technique is also suitable to use to test co-integration when a small sample data is used and does not require the underlying variables to be integrated of similar order. The Vector Error Correction Model (VECM) Granger causality was also employed in the study to establish the causality between economic growth and electricity supply. It was chosen for its ability to develop longer term forecasting, when dealing with an unconstrained model. The results from the ARDL bounds test showed that there is a long run relationship between economic growth, electricity supply, power outages and employment. Based on the causality tests, the findings showed a unidirectional causality flowing from electricity supply to economic growth. This implies that electricity supply affect economic growth in South Africa. The results further showed no causality flowing from economic growth to electricity supply which indicates that when economic growth is booming fewer funds are used for improvement of the electricity generation. Lastly, the results showed that power outages negatively affect economic growth in the long run. To sum up, electricity supply is an important factor for economic growth in South Africa. It is therefore necessary that South Africa must put in place measures aimed at stimulating electricity supply. One of the measures aimed at increasing output of electricity is to unbundle the electricity sector. This process involves allowing entry of the Independent Power Producers (IPPs), Independent System Operator (ISO) and Regional Electricity Distributors (REDs). This will lead to increased supply of electricity and competitively lower prices of electricity. The study further recommends that renewable energy sources should be used to produce electricity instead of coal and nuclear fuels as they failed to produce enough electricity for the nation.

- Description: A number of authors have portrayed leadership as a vital factor in the success or failure of an organization. Hence Bass (1994; 1997) believes that excellent organizations begin with excellent leadership and organisations reflect their leadership (Maritz, 1995). Therefore, successful organisations reflect their leadership (Maritz, 1995). In an attempt to investigate the aim of this research, various performance and leadership concepts and theories were investigated: the trait concept, behavioural approaches and situational/contingency approaches. Every one of these theories gave a different explanation to leadership. Furthermore, transactional, and transformational leadership were also discussed. The difference between these two models according to Bass and Avolio (1994) is that the work performance of the followers of transformational leadership is usually beyond expectations, while transactional leadership, at best, leads to expected performance. In terms of performance, it is argued that employee work performance can lead to a successful organisational performance. This is because several organisations attribute their business success to the work performance of their employees. According to Collis and Montgomery (1995) employee work performance has a major positive influence on organisational performance. Nevertheless, the accomplishment of an organisation is dependent on the leader’s ability to enhance human resources; hence “effective organisations require effective leadership” (Maritz, 1995). Transformational leadership was identified as the effective leadership style that can motivate workers to improve on their performance by instilling trust and confidence in them. Transformational leadership is superior to both transactional and non-transactional leadership because it makes workers loyal to the mission and vision of their organizations. Bass (1990) states “that the leadership research over the years has proved that loyalty is more powerful than tangible inducements.” Furthermore, non- transactional leaders avoid decision making, allowing their subordinates to take charge of the work process (Bass 1990). This research focuses on the relationship between leadership and employee work performance in a Nigerian Courier Company. In addressing this aim, a Nigerian Courier company was selected as the research context because of its success in the Nigerian turbulent business environment that is plagued by the country’s economic, social, and political troubles (McKern, Meza, Osayande and Denend, 2010). The research hypothesis of this research was generated to investigate leadership and employee performance. Leadership and performance were also identified as the research independent and dependent variables. Thus the research hypotheses were as follows: Hypothesis 1. Null Hypothesis: There is no significant positive linear relationship between employee performance and transformational leadership Alternative Hypothesis: There is significant positive linear relationship between employee performance and transformational leadership Hypothesis 2. Null Hypothesis: There is no significant positive linear relationship between employee performance and transactional leadership Alternative Hypothesis: There is significant positive linear relationship between employee performance and transactional leadership Hypothesis 3. Null Hypothesis: There is no significant positive linear relationship between employee performance and non-transactional leadership. Alternative Hypothesis: There is significant positive linear relationship between employee performance and non-transactional leadership. The general methodology included the use of a valid and reliable instrument known as the Multifactor Leadership Questionnaire (MLQ) and the company’s performance appraisal process. These instruments were used to collect information about employee work performance. The validity and reliability of the MLQ is not in doubt because it was formulated from the full range leadership development theory of Bass and Avolio (1997) and has been used extensively worldwide (Bass and Avolio, 1997). The research data was analysed using Statistica (StatSoft, 2011). Once the data was imported the necessary leadership factors were calculated as per the MLQ scoring key. From the eight factors a further three factors were generated namely transformational, transactional and nontransactional leadership. The data was checked and described using frequency tables and descriptive statistics, followed by correlation matrices coupled with their corresponding scatter plots. The research data was tested for consistency and reliability. Sekaran (2000) states that in order to determine the reliability of a measure one needs to test for both consistency and stability. For this research, linear correlation and regression analysis was used. The outcome of the first investigated hypothesis confirmed that there is a strong significant, positive linear relationship between employee performance and transformational leadership (ρ<0.0001). However, the findings on the null hypothesis, states that transformational leadership has no significant positive linear relationship with employee performance. The null hypothesis is REJECTED, because the model is significant at ρ<.0001. Thus, the alternative hypothesis is ACCEPTED because it concludes that there is sufficient evidence, at the 5% level of significance, that there is significant positive linear relationship between employee performance and transformational leadership. The second hypotheses found that with 5% level of significance there is no significant positive linear relationship between transactional leadership and employee performance (ρ =0.317). It must be noted that since the correlation is not significant the null hypothesis which states that there is no significant positive linear relationship between employee performance and transactional leadership was NOT REJECTED. The outcome of the third hypotheses support the null hypothesis, because the negative linear relationship between employee performance and non-transactional leadership is not significant (ρ = 0.6718). This informed the conclusion that at the 5% level of significance, there is no positive linear relationship between non-transactional leadership and employee performance. The findings of this research favour the conclusion drawn by Brand, Heyl and Maritz (2000) that suggested a more significant relationship between transformational leadership and employee performance, than any other leadership style. Evidence put together in the retail and manufacturing sector of South Africa, and the armed forces of the United States of America, Germany and Canada, point in the direction of the strong, positive effects of transformational leaders (Brand, et al., 2000). Again the effectiveness of transformational leadership can be reinforced by the research directed by Ristow, Amos and Staude (1999), which resolved that the effectiveness of transformational leadership was greater in a South African cricketing environment. Hayward, Davidson, Pascoe, Tasker, Amos and Pearse (2003) conducted research in a pharmaceutical organisation and found a positive linear relationship between transformational leadership and employee work performance. These research outcomes clarify the investigation by Pruijn and Boucher (1994) which established “that transformational leadership is an extension of transactional leadership” (Bass, 1997). The difference between these two models according to Bass and Avolio (1994) is that the work performance of supporters of transformational leadership is usually beyond expectation, while the behaviour of the supporters of transactional leadership, at best, leads to anticipated work performance. This research will be used to improve the relationship between the leaders and employees of the courier company under investigation. It will be useful for the placement of individuals to leadership positions in the company. It will also impact on how future leadership training will be conducted by the company, and of course add to the body of knowledge. This is supported by research conducted in the service sector which states that “transformational leadership affects performance over and above transactional leadership” (Geyery and Steyrer, 1998).

Using the 2008 National Income Dynamics Survey, the relationship between marital status and life satisfaction is heterogeneous. In the overall sample, life satisfaction is significantly higher for married compared to widowed individuals, while the former are more satisfied than those from all other marital statuses. In the overall and female samples, married people are more satisfied compared to those from all other marital status groups. Married men are not significantly more satisfied than men from other marital statuses as a whole. Marriage is positively associated with life satisfaction among women, but not among men.

- Description: A study of the available literature on Psychological WellQBeing and Positive Organisational Scholarship revealed that enormous potential existed for further research. This is a relatively new field with limited literature and research evidence available. It became very clear from the beginning that the relationships between these constructs could successfully be researched. It was therefore decided to embark on an academic research journey in order to contribute to the existing knowledge available on these constructs within the South African Private Healthcare Industry. This quantitative research was used to obtain more clarity about the relationships between the two constructs and to gather the responses from the research population. The research sample consisted of 152 nursing staff. Two questionnaires were integrated to develop the Nursing Psychological WellQBeing Questionnaire and consisted of i) PsyCap Questionnaire developed by Luthans, Youssef and Avolio2007, and ii) Psychological WellQBeing Questionnaire developed by Ryff 2000. A total of 152 nursing staff responded to an 87–item paperQbased questionnaire. Four research questions were formulated and covered the following: •The content, validity and portability of the measuring instruments; •The configuration of the various constructs; • Relationships between some of the variables . The content and the structure of the measuring instruments were assessed by means of Confirmatory Factor Analysis (CFA) and) Exploratory Factor Analyses (EFA). These assessments showed that the original measuring instruments are not portable to a culture which is different to the one where they were originally developed. The relationship between dimensions of Psychological WellQBeing and PsyCap sense of achievement and optimism is a significant finding. The significance of the findings of this study and the contribution that it makes to the existing theory is seen in the importance of the portability of measuring instruments. Recommendations in this regard have been made in Chapter 5. Various findings have also highlighted the relationships between Psychological WellQBeing and PsyCap. The importance of future research topics has been recommended.

The relationship between the value chain and project success in the Malawian construction industry

- Description: The construction industry in Malawi plays a vital role in developing the infrastructure of the country that is in need of improvement. Thus, in order to improve the quality of infrastructure in Malawi, the construction industry has to perform better than the status quo. The construction industry is characterised by a complex value chain that comprises of clients, consultants, contractors, and material manufacturers, suppliers, financing institutions, knowledge organisations and regulatory authority. This research looks at the relationship between construction value and project success in the Malawian construction industry. A qualitative research method was used for compiling the primary data for the study. Twenty-nine (29) participants were interviewed. These participants represented clients, consultants, contractors and material suppliers. The findings reveal that value creation in Malawi is characterised by lack of harmonised standards and specifications, inconsistent project management practices, existence of non-value adding activities, corrupt practices, lack of a skilled labour force, and lack of commitment to best practices in H&S as well as environmental management. Further, logistical problems affect the supply of construction materials to the country; while an unfavourable economic environment makes pricing of materials a challenge in the country too. Poor communication and limited use of information technology (IT) is very common in the industry and project implementation is also affected by a poor road network, an intermittent power supply, and a lack of cooperation from other service providers. In terms of supply chain structures in use, the research revealed that the traditional procurement method that is based on the lowest bidder / price is the most dominant method in use and very few members of the construction industry are conversant with other procurement methods. The method is also the preferred procurement method used by public sector clients. The performance of the traditional procurement method largely depends on the competence of the project design and supervision team, the adequacy of the documentation, and the capacity of the contractor. However, in most cases the system has failed to perform due to the poor contract management skills of the supervising consultant and the lack of timely guidance from the public sector clients. The findings also revealed that most of the suppliers or subcontractors are engaged on project based relationships, and members of the industry are unwilling to engage in long terms relationships due to mistrust and greed among members of the industry, and also largely due to lack of proper frameworks that can support such relationships. It is therefore recommended that other procurement methods should be explored and the engagement of the lowest price bidders should be discontinued on small and medium scale projects. The criteria for upgrading contractors to higher categories should equally be revisited to eliminate incompetent contractors. The NCIC should take a leading role in harmonising the various standards and specifications in use in the country. Promotion of the usage IT services should be encouraged to facilitate faster information dissemination. Usage of risk management in construction and evaluation and monitoring of projects should be encouraged and benchmark best practices. Finally, the members of the industry should take up the responsibility to take leading entities in the industry to task, if fundamental changes are to take place in the industry.

- Description: The construction industry in Malawi plays a vital role in developing the infrastructure of the country that is in need of improvement. Thus, in order to improve the quality of infrastructure in Malawi, the construction industry has to perform better than the status quo. The construction industry is characterised by a complex value chain that comprises of clients, consultants, contractors, and material manufacturers, suppliers, financing institutions, knowledge organisations and regulatory authority. This research looks at the relationship between construction value and project success in the Malawian construction industry. A qualitative research method was used for compiling the primary data for the study. Twenty-nine (29) participants were interviewed. These participants represented clients, consultants, contractors and material suppliers. The findings reveal that value creation in Malawi is characterised by lack of harmonised standards and specifications, inconsistent project management practices, existence of non-value adding activities, corrupt practices, lack of a skilled labour force, and lack of commitment to best practices in H&S as well as environmental management. Further, logistical problems affect the supply of construction materials to the country; while an unfavourable economic environment makes pricing of materials a challenge in the country too. Poor communication and limited use of information technology (IT) is very common in the industry and project implementation is also affected by a poor road network, an intermittent power supply, and a lack of cooperation from other service providers. In terms of supply chain structures in use, the research revealed that the traditional procurement method that is based on the lowest bidder / price is the most dominant method in use and very few members of the construction industry are conversant with other procurement methods. The method is also the preferred procurement method used by public sector clients. The performance of the traditional procurement method largely depends on the competence of the project design and supervision team, the adequacy of the documentation, and the capacity of the contractor. However, in most cases the system has failed to perform due to the poor contract management skills of the supervising consultant and the lack of timely guidance from the public sector clients. The findings also revealed that most of the suppliers or subcontractors are engaged on project based relationships, and members of the industry are unwilling to engage in long terms relationships due to mistrust and greed among members of the industry, and also largely due to lack of proper frameworks that can support such relationships. It is therefore recommended that other procurement methods should be explored and the engagement of the lowest price bidders should be discontinued on small and medium scale projects. The criteria for upgrading contractors to higher categories should equally be revisited to eliminate incompetent contractors. The NCIC should take a leading role in harmonising the various standards and specifications in use in the country. Promotion of the usage IT services should be encouraged to facilitate faster information dissemination. Usage of risk management in construction and evaluation and monitoring of projects should be encouraged and benchmark best practices. Finally, the members of the industry should take up the responsibility to take leading entities in the industry to task, if fundamental changes are to take place in the industry.

- Description: This study aimed to provide insights into the manner in which the representation of social media usage in relation to cyber-related crimes within selected South African newspapers can potentially shape the ideas and perceptions that society may have towards social networking channels. Drawing on the literature from fields such as developmental studies, new media studies, identity formation and cyber-criminality, an analysis of the Price Water House Coopers Global Economic Survey (2011) was used to provide some insight into the issue of cyber-crime within South Africa. The survey which was conducted by Price Water House Coopers revealed that South Africa is ranked second in the world with the highest rate of reported fraud cases. According to them this rate is comparatively higher than the escalating percentage of cases reported in the United States and other nations. In order to correlate and illustrate some of the findings of the survey and that which was found through primary research, an in-depth content analysis applying limited designations analysis and detailed assertions analysis techniques (Du Plooy, 2007) has been performed on selected content from local print and online publications such as The Herald, Algoa Sun, The Weekend Post, The Sunday Times and News24, from the time period of January 2009 until January 2012. Herewith, a total of 125 articles were analysed in order to determine the tone and thematic nature of the communication within the respective platforms. Furthermore, the mass media has been argued as being the main platform of communication within society. Whereby, different communication techniques are used to communicate with different target audiences. On a theoretical level, the study explored whether or not social media perpetuates the prejudices of the modernisation theory or serves to challenge such prejudices. Furthermore, the study explored whether social media may potentially have an impact on the reported cyber-related crimes. Associated theory such as the representation theory, globalization, the privacy trust model, social contract theory, media richness theory, participatory theory, convergence, the digital divide, media-centricity, dependency and identity formation has been explored. It was found that social networking sites Facebook and Mxit have been represented as the most common platforms of cyber-related crime and women and teenagers are the most popular victims. The likelihood of individuals being exposed to cyber-crime within social networks is high due to the fact in order to develop online relationships, personal information needs to be shared. The Privacy Trust model was identified as being an important factor which shaped the findings of this study. This is due to the fact that a certain level of trust is held by social network subscribers to the Internet hosts who they entered into a social contract with and with their friends.

- Description: The majority of small-scale farmers in the Eastern Cape apply inadequate quantities of manure, inorganic (NPK) fertilizer and Gromor as lone fertilizers or tend to mix manure or Gromor with chemical fertilizers for crops, without any scientific basis (Mkile, 2001). Hence this study – aimed at achieving effective and efficient use of chemical fertilizers, manure and Gromor, either as lone fertilizers or mixed with one another, in maize production – was established. A three-year dry land field experiment, arranged in a RCBD with 3 replicates where cattle manure, chemical fertilizer and Gromor were mixed at different ratios – as treatments FM1 (10 percent fertilizer + 90 percent manure); FM2 (25 percent fertilizer + 75 percent manure); FM3 (50 percent fertilizer + 50 percent manure); MAP (100 percent fertilizer); M (100 percent cattle manure); FG1 (10 percent fertilizer + 90 percent Gromor); FG2 (25 percent fertilizer + 75 percent Gromor); FG3 (50 percent fertilizer + 50 percent Gromor); G (100 percent Gromor) and a control (with nothing applied) – was conducted at the Nolukhanyo agricultural project at Bathurst in the Ndlambe Local Municipality. Maize cultivars PAN 6480 and Sahara were used as test crops. Manure, Gromor and soil were analyzed for their nutrient composition. Data recorded involving number of kernels per cob-1, grain and dry matter (DM) yields for the 2010-11, 2011-12 and 2012-13 seasons, and leaf area index (LAI) – were subjected to Genstat Version 14.1 for statistical analysis. Grain yields of PAN 6480 and Sahara recorded in seasons 2010-11, 2011-12 and 2012-13 were significantly higher (p≤0.05) than those of the controls. In 2012-13, PAN 6480 on treatments FG3 and FG1 produced the highest grain yields (5 327 and 5 107kg ha-1) respectively, while in 2010-11 the highest yield was 3 780kg ha-1. In the 2012-13 season, Sahara on F treatment was the highest with 4 553kg ha-1 whilst there were no significant differences in F and M treatments. Dry matter yields of Sahara were higher than those of PAN 6480 in all seasons. The highest Sahara LAI obtained on FM2 was 5.85 in the 2012-13 season, whereas PAN 6480 had LAI of 4.77 on F treatment, followed by FG3 with 4.72 LAI. PAN 6480 number of leaves for 6 plants in m2 and LAI in week 8 of the 2012-13 season had a positive correlation, r2=0.84. PAN 6480 number of kernels and cob length in the same area correlated quite well (r2 =0.91). Chemical fertilizer corrects the imbalances of nutrients inherent in organic manures and increases both maize grain yields and dry matter yields, and also influences number of leaves and LAI. Treatments FG1, FG3 and FM1 of PAN 6480 resulted in high maize grain yields when planted 13 in late November of the 2012-13 growing season and when water in the soil profile was conserved as a result of good rains received prior to planting. Treatments FG1 (10 percent fertilizer + 90 percent Gromor), FG3 (50 percent fertilizer + 50 percent Gromor) of PAN 6480 produced the highest grain yields (5 107kg ha-1 and 5 327kg ha-1 respectively) in the 2012-13 season, whilst FM1 (10 percent fertilizer + 90 percent manure) gave the highest grain yield (of 4 277kg ha-1) for the same cultivar in the 2010-11 season.

- Description: The most recent surveys in South Africa estimate that invasions are still increasing, despite substantial clearing efforts. Riparian systems in South Africa are particularly vulnerable to invasion by woody IAPs. This thesis addresses the restoration of alien‐invaded riparian systems, by investigating the factors that facilitate or constrain spontaneous recovery and influence the trajectories of succession. These factors include invasion history and management history, especially the use of fire. A seedling emergence approach was used to test the presence of a viable pre‐fire seedbank, and the effect of fire on the seed bank. The efficacy of some active restoration interventions was also tested, with the aim to return invasion‐resistant, indigenous vegetation with a structure and function representative of uninvaded sites. The findings of this study indicated the presence of a viable and persistent riparian soil seed bank, even after 30 years of intermtittent invasion as well as two fire cycles under invasion. It shows that the management practice of fell‐and‐burn resulted in high soil temperatures, and that this reduced the indigenous soil seed bank density, especially in the upper soil layer. Clear germination sequences and patterns of emergence over time for different species were observed during this study, with many species exhibiting delayed emergence relative to the timing of the fire event. It is proposed that manipulation of the season of fire could be used to selectively optimise the order of arrival and therefore superior recruitment of some species over others in the Eastern Cape fynbos, and thus alter the trajectories of recovery of vegetation towards a more desired state. Active restoration in the form of indigenous seed and plant additions resulted in a significantly higher indigenous cover after seven months, compared to a control (passive restoration) or restoring with grass. Indigenous cover and composition was also strongly influenced by lateral zonation, and some key guilds and species were missing or present in much lower densities compared to reference sites. Grass restoration significantly suppressed the regeneration of A. longifolia, as well as the regeneration of indigenous species. Biotic resistance can thus be achieved through restoration, and it could be a powerful tool in the management of IAPs, although the deliberate introduction of grass after clearing in fynbos also reduces biodiversity and could have unforeseen consequences to riparian function.

- Description: The majority of South African public schools are not performing well considering the overall learner success rates in specifically so called disadvantaged schools. Many factors contribute to this situation, however, all education stakeholders contribute in some way to the success or failure of schools. In this regard alumni of disadvantaged schools in South Africa have not played an active role in supporting their alma maters. This research sought to identify the various roles alumni can play in the development of disadvantaged schools. As innovative strategies to the public education crisis in South Africa are required, one such strategy is to involve a neglected stakeholder group such as alumni to share their skills and resources towards improving the different aspects of school development. There are very few examples of functioning alumni associations at previously disadvantaged schools in the Eastern Cape. Sharing information on a study of two selected schools with already established alumni associations could be of value to other schools in the establishment of their own alumni associations in order to support school improvement and development initiatives. Therefore, based on the findings of this study and from evidence in literature, the researcher concludes that alumni associations can play a meaningful role in developing and transforming disadvantaged schools in a young and developing democracy as in the case of South Africa. This study looked at, amongst other aspects, at the roles and contributions that alumni may play in the development of their alma maters and finally offer guidelines in the establishment of alumni associations.

This was an inevitable piece of study to undertake especially from the point of view to examine which form and philosophy of unionism suits the public sector best. The wildcat strikes and unprotected industrial action that grip municipalities at 10 o’clock early in the day needs deeper thinking and new ground-breaking solutions. Very fundamental questions have to be examined to determine the extent of control SAMWU as a union have over the strategic management environment of the local sphere of state. Lukhanji municipality, given its strategic location happened to host many regional offices of all COSATU affiliated unions happens to be an inconvenient choice of the nucleus of radical trade unionism in Queenstown fall victim and the study examines that. Subsequently to that the municipality fell victim to rigid and radical forms of trade union operations that has strangled it to the point of it losing its character and role of a developmentalist institution in the communities it served. The study also highlights the severe service delivery backlogs in both former Transkei Ezibeleni and Ciskei Whittlesea and how transformation and integration of these two areas have been neglected as shown by the socio-economic profile. The study in the last Chapter makes particular recommendations on how the Strategic Management environment and corporate principles should be prioritised for Performance Management to be introduced and routinely implemented. , Thesis (MPA) -- Faculty of Management and Commerce, 2013

- Description: The purpose of this study is to investigate the role played by agricultural cooperatives in developing the rural areas of the Eastern Cape Province. It also looks at the contributions by Government in promoting the establishment and the success of these cooperatives. The focus area was Cannon Farm in the Chris Hani District Municipality, where most of the people live below the poverty line, but have started agricultural cooperatives with the aim of eradicating poverty and developing their communities. The data for this research was gathered through group discussions and face-to-face interviews which were guided by a questionnaire. A document analysis was also conducted to fulfill all the research objectives. It has been found that agricultural cooperatives, as compared to any other type of cooperatives, are a major tool to eradicate poverty and bring economic development to rural communities. This is made possible not only by the full commitment and determination of cooperative members, but also by government which has also committed itself to providing a supportive legal environment for cooperatives (Cooperative Act No. 14 of 2005). The findings also show that, due to the challenges they are currently facing, agricultural cooperatives in the Eastern Cape Province have not yet reached their full potential. Therefore, it has been recommended that, such challenges need to be urgently addressed. As the United Nations (2001) highlights, agricultural cooperatives present themselves as an important element that can contribute to the realization of the Millennium Development Goals by 2015.

- Description: The purpose of this study is to investigate the role played by agricultural cooperatives in developing the rural areas of the Eastern Cape Province. It also looks at the contributions by Government in promoting the establishment and the success of these cooperatives. The focus area was Cannon Farm in the Chris Hani District Municipality, where most of the people live below the poverty line, but have started agricultural cooperatives with the aim of eradicating poverty and developing their communities. The data for this research was gathered through group discussions and face-to-face interviews which were guided by a questionnaire. A document analysis was also conducted to fulfill all the research objectives. It has been found that agricultural cooperatives, as compared to any other type of cooperatives, are a major tool to eradicate poverty and bring economic development to rural communities. This is made possible not only by the full commitment and determination of cooperative members, but also by government which has also committed itself to providing a supportive legal environment for cooperatives (Cooperative Act No. 14 of 2005). The findings also show that, due to the challenges they are currently facing, agricultural cooperatives in the Eastern Cape Province have not yet reached their full potential. Therefore, it has been recommended that, such challenges need to be urgently addressed. As the United Nations (2001) highlights, agricultural cooperatives present themselves as an important element that can contribute to the realization of the Millennium Development Goals by 2015.

- Description: Despite 19 years of democracy and public action by civil society, policy makers continue to neglect the role of agriculture in improving the quality of life in rural areas such as Ncora in the Eastern Cape. The communities in the Ncora area still experience poverty despite the fact people receive state grants. Agriculture is declining in this area without basic infrastructure. The study argues that communities in the Ncora area need assistance from government in order to increase agricultural activities. These activities are an important route through which these communities can reduce poverty. The primary objective of this study was to obtain a better understanding of the role of agriculture in reducing poverty in the Ncora rural areas. The conditions necessary to sustain agriculture in the rural areas were identified. This was mainly done to help alleviate the plight of rural areas in the Ncora area and to improve the quality of life of the rural population. The study was based on three research objectives. The first objective was to investigate the constraints to agricultural production in Ncora. The second objective was to ascertain what has been done by the Eastern Cape government in increasing agricultural activities. The third objective was to investigate the contribution of agriculture in reducing poverty in Ncora. The main finding in terms of the first research objective is that constraints to agricultural production in Ncora are structural constraints. These include inadequate infrastructure such as poor roads, lack of transport and equipment, lack of farming skills, poor quality seed, no access to markets, inadequate and unaffordable services. In terms of the second research objective, the main finding is that the government has encouraged investment in infrastructure using labour-intensive methods will eliminate service backlogs in underserviced areas such as Ncora. Secondly, it has encouraged the revival of irrigation schemes such as the Ncora irrigation scheme and is investing in human capital through the empowerment of people in order to improve the quality of life of the Ncora community. Empowerment involves skills and training, education and access to basic services, expertise regarding credit, land and the growing of vegetables. The development of human capital is an important determinant of the pace of economic development. Human, social, natural, financial and physical capital are essential elements of reducing poverty. In fact, the Ncora community has lobbied Intsika Yethu Municipality for community development Community development through education and community participation in development programmes. Efforts have to be made to increase the skills that will enable them to complete development projects. These include technical skills in areas such as vegetable and crop production during the year. A key component of the success of development projects is to involve communities in the planning and decision-making processes. Community development is linked to empowerment, in other words, empowered people are able to contribute to the development of their community because they have knowledge of the economic, social and political goals of development. Therefore, empowerment enables people to participate in and have an influence on the decisions that affect their lives. The main finding in terms of the third research objective is that people in the Ncora community are using their own labour to improve food production to reduce poverty. The Ncora community has been shown when and how to make, grow and plant seeds, and look after the vegetables of their choice. The community of Ncora has learnt about cropping practices that are appropriate to their situation. The intention is to sell vegetables and crops to local communities and markets in order to generate income. The community has to do it for themselves or else they will wait forever.

- Description: The aim of the study was to investigate the role played by urban agriculture (UA) in alleviating poverty in poor and low income households of Harare. It further examined the factors that confront the practice. The study was conducted after a realisation that despite not receiving much support from city by- laws, poor and low income households of Harare continue to engage in agricultural activities yearly. The desk research method was used to acquire information from a vast of secondary data sources. The secondary sources which were qualitative in nature provided the research with broad literature on urban agriculture and poverty in Harare, Zimbabwe and the world at large. However, a case study research design was employed whereby an in-depth analysis of the topic focused on poor and low income farmers of Harare Province. Literature reviewed and analysed was organised into themes and categories that portrayed urban agriculture as a crucial tool for alleviating poverty. It was also viewed as a tool that can be used as a sustainable livelihood. Despite other factors affecting the performance of urban farmers, lack of clear policies and city by- laws that guide agriculture in the study area proved to be a huge hindrance. Therefore, to achieve sustainable livelihoods and reduce poverty, the research suggested that instead of different pieces of city by- laws governing the practice in Harare and Zimbabwe there is need for one clear urban agriculture policy. It was concluded that the government and city authorities remain the key to unlocking UA‟s full potential by providing formal support to the practice by organising formulation of an inclusive urban agriculture policy that will be understood by every citizen.
