- Description: The aim of this thesis is to provide a differentiated view of peri-urban agriculture in the context of urban population growth in Asmara, Eritrea. Peri-urban agriculture is viewed as a distinct type of broader urban agriculture, and in this case is not as subsistence-orientated as other branches of it. Urban population growth is comprised of three elements, namely, natural population increase, rural-urban migration and outward movement of people to the urban periphery linked to urban expansion. Each receives extensive treatment. Asmara is the capital city of Eritrea and using Weeks (2004:473) phrase can be termed as a “primate city”. As such, it exerts a major influence on the political, economic and cultural life of the country, but has never been subjected to this type of research. The analytical framework that is adopted is that of urban population growth. In order to operationalize it, theoretical insights into each of its three branches were applied. For example, the informalisation of the economy in developing cities was used to explain the operation of peri-urban agriculture in the context of natural population growth. An adaption of the original Harris-Todaro Model by Fields (2004) was used for the migrants, and the Mosaic Model by Bryant and Johnson (1992) for those facing urban encroachment. Primary data were collected in the field by the author with the help of research assistants. This was supplemented by secondary data which involved reports commissioned by the Ministry of Agriculture and the Ministry of Public Works. Focus Group discussions were also held to supplement the data with information, views and insights that do not emerge in one-to-one interviews. This thesis demonstrates that those respondents operating within the context of natural population growth make a viable living from peri-urban agriculture, but that they also recognise that there are considerable challenges to be faced. Three sub-groups of farmers are identified. Of these, poultry farmers are the most vulnerable because of the high costs of the inputs, the uncertainty associated with avian „flu and an undeveloped distribution network. The vegetable producers, on the other hand, have a sophisticated marketing network, but low levels of education, high household numbers and an impending shortage of land and water. The agriculturalists that have migrated to Asmara seem to have created sustainable occupations for themselves over a number of years. However, 75 percent of them felt that migration to Asmara was not worthwhile. This negative view is explained in terms of the struggle it has taken to maintain such a living and the growing shortage of land. This set of farmers achieves lower production levels than its city-reared counterparts, carries considerable expenses and has to hire its land. The farmers who have had to cope with urban encroachment fall into two classes. The first has chosen to remain in peri-urban agriculture despite feeling the pressure to scale down activities and thus have a lower income. The majority of this group are dairy farmers who have to trade off increasing costs of cattle feed against shrinking grazing land. They are unwilling to take the initiative to solve their land problems, but look to the authorities to do so. The second class of respondents in this category have abandoned their agricultural holdings. The majority of these agriculturalists are poultry farmers living in the Eastern side of the city. A shortage of agricultural land, high population densities and high costs of inputs make poultry farming difficult. This thesis, therefore, presents a multifaceted view of peri-urban agriculture. While each set of farmers has to cope with its own particular circumstances, there is a common factor. This is the tension between preserving agricultural land on the urban fringe and the need to expand the city to accommodate its inhabitants.

- Description: The study sought to evaluate the extent to which poverty alleviation programmes of the Eastern Cape Provincial Department of Rural Development and Agrarian Reform (DRDAR) addressed the agricultural needs of the Ndakana community. The emphasis had been on the effectiveness with which these programmes were implemented. Ndakana Village is situated in the Nqamakwe District. The village consists of Hili-hili, Mathafeni, Ncora and Diphini locations which are approximately twenty kilometres from the rural town of Nqamakwe in Amathole District. In the Eastern Cape, several poverty alleviation programmes are implemented which should, inter alia, alleviate the phenomenon of poverty in the rural areas. Despite these programmes it, however, appears that there is very little, if any, improvement in the poverty situation. Against this background it is essential that the progress in the alleviation of poverty be evaluated and if necessary, steps be taken to ensure that the envisaged objectives be achieved. On the importance of evaluating the program, Monette et al. (2011:5) write that in the past few decades, many large, ambitious expensive programmes intended to cope with social problems and to provide services to individuals have been developed. Along with the growth of these programs has emerged an increasing concern over their results: Do they achieve their intended goals? These programs are costly, and some evaluation is needed to assess whether resources are, indeed, being used effectively. Equally important, a program that fails to achieve its goals leave a problem unresolved or a service undelivered. Monette et al. (2011:6) further regard evaluation as a use of scientific research techniques to assess the result of a program and evaluate whether the program, as currently designed, achieve its stated goals In accordance with the Reconstruction and Development Programme (RDP) (1994:20), a national land reform programme is the central driving force of rural development. Such a programme aims to effectively address the injustices of the forced removals and the historical denial of access to land. The RDP aims to ensure security of tenure for rural dwellers in implementing the national land reform programme, and through the provision of support services, the South African government intends to build the economy by generating large-scale employment, increasing rural income and endeavours to eliminate overcrowding.

- Description: The use of mobile phones and other mobile devices are becoming widespread and almost all of these mobile devices have some sort of mobile Internet access. Due to the increase in mobile Internet usage, many websites need altering in order to become mobile compatible. Creating a mobile compatible version of a website is challenging due to formatting and capability restrictions imposed by the mobile device. Currently, one of the popular methods of creating a mobile compatible website involves the creation of a new, dedicated mobile version of the website. However, this approach can prove to be expensive, and repetitive, since a fully functional desktop version of the website often already exists. A second method involves the use of a transformation proxy to transform the traditional website into a mobile compatible version. This research develops a transformation framework that enables a web developer to create a single set of source files that can be used to render output compatible with both traditional and mobile devices. In developing this framework, capabilities and restrictions of the mobile device were examined. Furthermore, current mobile web development guidelines and best practices were discussed. This resulted in the development of a method to identify and outline areas of a traditional website for transformation into a mobile friendly format. Furthermore, a transformation engine that allowed processing of the traditional website into a mobile compatible website was developed. This transformation engine extracted the outlined areas, and rendered the extracted content, all while maintaining the website’s original functionality. The development of a prototype verified that the transformation concepts are valid, and provided for the development of guidelines and recommendations. The development of a framework to enable the web developer to create a website once, and enable it to adapt its output for mobile devices, will have a positive impact on the development of content for the mobile web.

- Description: This study was conducted in order to assess the effectiveness of technical analysis as a tool for financial security price forecasting. This form of analysis was examined so as to determine whether or not any benefit could be attributed to an investor or financial trader who applied it. Two technical trading strategies, consisting of three indicators each, were applied to fifteen financial securities over a five year period; so as to observe the price forecasting signals offered by the technical indicators. The resulting technical signals offered by the trading strategies were recorded and assessed for accuracy; allowing for various observations to be made; namely the forecasting precision of the technical strategies, the application of technical analysis in the equity and foreign exchange markets, the use of single or multiple technical indicators within a strategy, and the combining of technical analysis with fundamental analysis. The results indicated that the effective implementation of technical analysis could very well benefit the price forecasting practices of financial analysts and investors. However, it was determined that a fair amount of discretion on behalf of the analyst would be required when examining the signals offered by the technical indicators for the purpose of predicting financial security price movements.

- Description: The research was conducted in the Hewu area situated between Queenstown (20 km) and Whittlesea (15km) in the Eastern Cape Province of South Africa. In this area communal farming is practiced. Livestock and livestock products (wool) are the main sources of income. The farmers are mainly farming with Merino and Döhne Merino sheep. The lack of management systems (production, reproduction and management) for communal farmers resulted into ineffective communal farming defining the research problem. The research objectives set were: • To establish production norms for wool sheep. • To establish reproduction norms for wool sheep. • To establish effective management practices for wool sheep farmers. • To examine key constraints of wool sheep farmers. The farmers shear their sheep every 12 months usually in October of every year. The average wool production per sheep is 2.17kg. The clip averages a fineness of 19.1-20 micron. That is far below the wool production of the commercial farmers of the Eastern Cape who are producing between 4kg to 5kg per sheep at an average growing period of 12 months. The lack of proper fencing and camps causes major reproduction problems. The lambing percentage of the ewes is 94.85 percent. The weaning percentage referring to the reproductive efficiency of the mated ewes is only 17.24 percent. The survival rate of the lambs born alive is only 18.18 percent. Reproduction is the biggest problem of communal farms. Effective livestock- and grazing management systems for communal areas are essential for the successful development of farmers on communal grazing areas. Unfortunately the Hewu farmers still have many problems effecting their wool production and the production of lambs.

- Description: This study is aimed at determining the challenges relevant to discipline in schools, the causes for these challenges, the role of values in connection with discipline and the intervention methods and strategies that could solve these challenges. Communities, societies, governmental and non-governmental organizations all over the world are value-driven. The challenges in relation to discipline that currently exist in schools, could be seen as coming from societies. There are general attacks on “common sense” and “common values”. It seems that low academic achievements can be linked to moral degeneration and the only solution is moral education. In the light thereof, discipline has to do with order and behavior that is acceptable. We have therefore tried to establish what the challenges in relation to high schools are, and whether the values that have been taught and modeled contribute towards the quality of being disciplined and how the challenges to discipline are being addressed. Character education is highly rated because it helps with prevention of discipline problems and contributes towards a positive environment that promotes a positive attitude. Many teachers in South-Africa experience challenges to discipline in the classroom environment brought about by many factors. Despite the challenges there is little support from the relevant governmental departments. After the abolishment of corporal punishment which used to work as the most effective method, no alternatives were provided. Educators have to lean on their own reactive methods to manage attitude problems in class. It also seems that educators are not trained by the Department of Education to implement the newer discipline strategies. Teachers apply discipline based on their own personal teaching philosophies that seems right and acceptable to them. The study tries to establish which intervention strategies could best address the challenges in schools. The study follows a mixed (qualitative and quantitative) approach which uses an embedded design. The embedded design consists of a primary method that leads the research project. In this instance the primary method is qualitative while the secondary data are quantitative which plays a supporting role. The secondary methods which are quantitative are not prioritized but it is embedded. The datacollecting instruments which have been used for this study are questionnaires, focus group and personal interviews, The primary goal of this study is to determine what the main challenges are in South Africa that result in discipline are being challenged, being threatened and pressurised. To achieve the main goal it is necessary that the researcher determines through literature study how the term “discipline” has been historically understood, interpreted and managed, as there was a shift in emphasis on how the term “discipline” was understood 30 years ago compared to today. The researcher has done a complete literature study to determine what current, relevant literature sees as current challenges in relation to discipline and what has been done to solve it. The researcher gathers information through data-collecting to determine which challenges currently exist at schools. Research has been done on current solutions and intervention methods to determine if there are intervention methods that can deal with these challenges more effectively. The study also tried to research new intervention methods. The empirical study and also the literature study acknowledge that challenges according to discipline exists, that there are a link between discipline and values, that the teaching of values positively influences school communities and that intervention methods and techniques that exists are not effective

- Description: The primary research objective considered by this study was to determine the nature of the governance system employed by the Offerman Family businesses in ensuring that all company assets, resources and actions are directed at, and controlled in the achievement of established company objectives and are accounted for to all legitimate stakeholders. Four related secondary objectives were also examined. The Offerman Family businesses consist of three separate companies that all make clay bricks in some form. Over recent years, the Offerman Family businesses have grown and taken on various minority shareholders in these three separate companies. For this reason, the governance requirements of the businesses have changed significantly from when the businesses were smaller and owned by a single family. The literature review on which the study is founded commences with an overview of family business topics appropriate to the research. Following this introduction, the history of the Offerman Family businesses is presented through until the present day (August 2010). Topics of governance are then considered in depth with a particular focus maintained throughout on that most applicable to the Offerman Family businesses. The research followed a case study approach within the phenomenological research paradigm. The details of the methodology employed are provided including an explanation of the questionnaire used as the research instrument. The questionnaire was submitted to ten people capable of influencing governance in the Offerman Family businesses and a useful response rate of 90 percent was achieved. The findings of the research detail the nature of the governance system employed by the Offerman Family businesses. It appears that there are shortcomings with family governance while governance of the businesses seems to be facilitated by the presence of the requisite governance building blocks such as a board of directors. Nevertheless, these governance systems are currently not functioning optimally leaving considerable room for improvement. The study closes with a review of the secondary research objectives and the resolution thereof. A list of recommendations is provided, which if implemented, could assist the Offerman Family businesses towards improving governance. Recommendations towards additional research are offered followed by an explanation of the limitations of the study.

Over recent years, the Offerman Family businesses have grown and taken on various minority shareholders in these three separate companies. For this reason, the governance requirements of the businesses have changed significantly from when the businesses were smaller and owned by a single family. The literature review on which the study is founded commences with an overview of family business topics appropriate to the research. Following this introduction, the history of the Offerman Family businesses is presented through until the present day (August 2010). Topics of governance are then considered in depth with a particular focus maintained throughout on that most applicable to the Offerman Family businesses. The research followed a case study approach within the phenomenological research paradigm. The details of the methodology employed are provided including an explanation of the questionnaire used as the research instrument. The questionnaire was submitted to ten people capable of influencing governance in the Offerman Family businesses and a useful response rate of 90 percent was achieved. The findings of the research detail the nature of the governance system employed by the Offerman Family businesses. It appears that there are shortcomings with family governance while governance of the businesses seems to be facilitated by the presence of the requisite governance building blocks such as a board of directors. Nevertheless, these governance systems are currently not functioning optimally leaving considerable room for improvement. The study closes with a review of the secondary research objectives and the resolution thereof. A list of recommendations is provided, which if implemented, could assist the Offerman Family businesses towards improving governance. Recommendations towards additional research are offered followed by an explanation of the limitations of the study.

- Description: The quest for resilient cities has emerged as a strategy to mitigate and adapt the problems created by urban population growth and rapid urbanisation. Resilience has increasingly become an important urban policy discourse that challenge cities to reflect on their adaptive capacity to function in the face of adversity. Urban resilience in particular, amplifies the concern that urban spaces are the hub of heightened complexities of diverse risks. Across the globe, the concept of resilience is gaining momentum with many academic researchers discussing this phenomenon. In South Africa, the concept has been sparingly incorporated in a number of literatures with little focus on local government entities such as municipalities. In order to close this gap in the literature, and in response to the increasing use of the concept locally, this study explores the extent to which factors of resilience resonate within the Nelson Mandela Bay Municipality urban management practices. Based on the exploration of a wide array of literature from various disciplinary areas, this study examines the concept of urbanisation and the related challenges. It also critically explores the concept of resilience, its application in urban management as well as the attributes of the adaptive capacities that enable urban resilience. This research adopts the City Resilience Framework and Index developed by Arup in partnership with the Rockefeller Foundation to assess the levels of resilience in the Nelson Mandela Bay Municipality. The framework identifies four main dimensions used to measure resilience: People’s health and wellbeing, Organisation of the economy and society, Place of urban systems and services and Knowledge inherent in leadership and strategy. These dimensions form the basis of an integrative framework that provides an alternative lense through which cities can understand their unique attributes that contribute to their resilience. This research highlights the levels of resilience within the Nelson Mandela Bay Municipality and outlines practical implications for Nelson Mandela Bay Municipality’s management which can also be applied in other cities. This research adopts a positivist approach and applies statistical empirical measures using a quantitative analysis process. The research instrument in the form of a questionnaire was administered to the target population for data collection. Using the conceptual framework, the researcher applied statistical analysis to derive relationships amongst the variables to determine the degree of resilience in Nelson Mandela Bay Municipality using the four main dimensions of the framework. The findings of the study show the varying levels of resilience within NMBM’s practices. NMBM’s principal success areas include; providing basic houses, ensuring water and sanitation facilities, instituting effective labour policies, providing skills development and training facilities especially to the youth, enabling a conducive atmosphere for business development and the presence of an integrated development strategy. However, not much has been done in providing sufficient public health facilities, alternative energy sources, access to financial services, ensuring food security, enabling continuity of projects and activities through a funded budget, providing emergency medical services in the event of a disaster, high levels of corruption and insufficient deterrents to crime. Overall, the results show that NMBM has made good strides in enabling high level of resilience in its day to day operations. The findings of this study suggest that urban resilience is a continuous process that facilitates engagement leading to a dialogue and deeper understanding of a city.

- Description: An overview of recent literature and research indicates that stress in teaching is now a wellrecognised phenomenon. More specifically, research has found special education to be more demanding than mainstream education. However, in comparison with the literature on mainstream education, both South African and international research relating to special education do not occupy prominent status in the literature. This study thus aims to explore and describe the coping orientation and resources of teachers educating learners with intellectual disabilities. The sample consisted of 59 special education teachers (49 females and 10 males) in the Nelson Mandela Metropole who educate learners with intellectual disabilities. The special education teachers who agreed to participate in the study were requested to complete a biographical questionnaire, Antonovsky’s Orientation to Life Questionnaire (SOC-29) and Hammer and Marting’s Coping Resources Inventory (CRI). An exploratory, descriptive design was utilised in this study. The data for this study was analysed by using descriptive and correlation statistics. The Pearson Product-Moment Correlation Coefficient was utilized in order to explore and describe the relationship between the sense of coherence and the coping resources of the sample. Key findings include the following: Results from the SOC-29 revealed fairly high mean scores for the current sample. Results from the CRI indicated average mean scores on both the total coping resources scale and all five subscales. Significant positive relationships were found to exist between the SOC-29 and the CRI for the current sample. Significant positive relationships were also found between the SOC-29 score and some of the subscale scores of the CRI for the current sample. In general, the findings of the present study reveal a need for further research on special education teachers. The focus should not only be limited to the pathogenic orientation, but should include more salutogenic approaches to better assist special education teachers to more effectively cope with their challenging work environment.

- Description: Learner-centred education has been in force in all schools in the Republic of Namibia since 1996. Progress towards adoption of learner-centred methods of teaching by teachers has been slow. The main purpose of this study is to examine how teachers understand the principles of learner-centred education in selected Secondary Schools in Omaheke Education Region. The secondary purpose of this study is to determine how teachers could be helped to improve the implementation of learner-centred education (LCE). The study used a qualitative approach. Data were collected from a purposively selected sample of Grade 10 accounting teachers in a specific region in Namibia by means of interviews, classroom observations and a qualitative questionnaire. Data were analysed thematically. The results indicated that, although the teachers had a positive attitude towards learner-centred education, they did not have the skills to adapt their teaching in an appropriate way to cope with the learner‟s lack of English literacy. The teachers possessed basic knowledge of learner-centred education practices, but found it very difficult to implement them in resource-poor environments. In addition, factors that hindered the effective implementation of learner-centred education in the classroom were identified. The study suggests ways to improve the knowledge and practices of teachers with regard to learner-centred teaching practices.

- Description: Trophic cascades involving large terrestrial mammals are very seldom empirically demonstrated. The high species diversity often associated with terrestrial systems is thought to modulate the strength of trophic cascades. In speciose systems, species often vary in vulnerability to consumption, hence some species are less responsive to top-down pressure. African large mammalian herbivores are highly diverse and vary greatly in body size, a characteristic linked to vulnerability to predation. Moreover, Africa is one of the last places to still support megaherbivores, species that have grown large enough to be practically impervious to non-human predation. Thus an African ecosystem is the ideal setting to explore trophic cascades in speciose terrestrial systems. In this study I explored patterns in trophic interaction amongst carnivores, vulnerable mesoherbivore and predator-invulnerable megaherbivores in an intact African savanna at a variety of spatial scales. I examined the mechanistic links between trophic levels at the patch scale through fine scale empirical manipulation of predation risk. In addition, I assessed the landscape scale biological relevance of these trophic interactions through correlative observations over large spatiotemporal scales. I present the first evidence of community level trophic cascades explicitly involving megaherbivores. I demonstrate how megaherbivores’ disregard of predation risk masks the effects of predator-triggered trophic cascades and weakens their impact on the ecosystem. The risk of predation triggered a spatial response in vulnerable species, driving them into safe areas, yet did not influence the space use of megaherbivores. This species-specific spatial response had contrasting effects on nutrient distribution. Vulnerable herbivores’ fear-induced foraging behaviour led to localised nutrient accumulation whereas the foraging behaviour of predator-invulnerable megaherbivores led to nutrient redistribution across the landscape. In addition, the fear-driven spatial differences in mesoherbivore grazing impact and nutrient deposition led to landscape scale changes in the distribution and persistence of herbivore maintained grass communities, so-called grazing lawns. However, the grazing activity of the in-vulnerable megagrazer, white rhino (Ceratotherium simum) weakened the effect of this trophic cascade by creating and maintaining grazing lawns within the risky habitat avoided by mesograzers. This study contributes to our understanding of what drives the variation among patterns of trophic control and provides the first evidence of the modulating influence that megaherbivores have on predator-triggered trophic cascades.

- Description: The effectiveness and relatively low cost of herbicides has led to the near exclusion of non-herbicide methods for controlling weeds in commercial forestry plantations. However, any herbicide used within the forestry context has the potential to be toxic and/or alter ecosystem dynamics. In response to increased public concern, perceptions of risk, and compliance associated with forest certification standards and criterion, there is an increased need to provide alternative methods that can reduce reliance on herbicides. Even though adequate research has been implemented regarding herbicide use, little research has examined the implications of herbicide use or non-use throughout the full rotation. Since herbicide use is integrated within the management of eucalypt regeneration, it is critical that a comprehensive understanding of herbicide use be obtained before informed management decisions can be made. Only once this has been obtained, can reduced and judicious recourse to herbicide use be considered, both within the requirements of certification criteria and of good management practice (economic and site sustainability). The main objective of this thesis was to increase the understanding of herbicide use, as well the cost involved within the context of eucalypt coppice regimes in South Africa. Three field trials (two rotation-end, and one short-term) were implemented to achieve this objective, with herbicide use aimed at either killing eucalypt stumps if replanting, or control of secondary coppice regrowth if coppicing. The first trial was situated in Mpumalanga and evaluated which method of control would be best suited to reducing cost (cost-effective) and reliance on herbicides for killing eucalypt stumps and control of resulting coppice regrowth. Selected cut-stump and basal-frill treatments were included with triclopyr (480 g L-1 a.i.) applied to the cambium of difficult-to-kill Eucalyptus macarthurii H. Deane & Maiden stumps that had previously been coppiced multiple times. The resulting coppice regrowth was either manually removed, or glyphosate (360 g L-1 a.i.) applied to foliage. These treatments were integrated with non-chemical control methods, where E. dunnii Maiden seedlings were planted either between each stump row or within the row, to determine whether such treatments could further reduce the level of coppicing through shading. At rotation end, the different treatments tested had no significant influence on any of the E. dunnii growth variates. As there were no significant differences, the treatment with the lowest overall cost and herbicide used would be preferred. The application of triclopyr to the cut-surface following felling was the most cost-effective treatment. The differences in cost obtained is directly related to required follow-up coppice regrowth control operations and quantity of total herbicide applied (both triclopyr and glyphosate). It was hoped that the non-chemical control method (planting position of seedlings) would reduce the level of coppicing, however, within this trial, this did not occur. The second trial was situated in Zululand on Eucalyptus grandis x E. urophylla coppice that investigated different methods to control secondary coppice regrowth through either manual removal with a bush-knife, or the application of glyphosate (360 g L-1 a.i.) to the foliage. A range of herbicide rates (0.6%, 1.2% and 1.8%) was applied to the foliage of the secondary coppice regrowth when it reached a predetermined mean height (0.5 m, 1.0 m and 1.5 m). The objective was to determine the optimum rate and timing of control and to avoid glyphosate from being over-applied when managing this regrowth. No significant differences were detected between the different treatments for any of the growth variates at rotation end. The use of glyphosate, irrespective of rate and/or timing of application (as assessed by secondary coppice regrowth height) proved to be more cost-effective compared to manual removal of secondary coppice regrowth. Treatment efficacy in terms of treating secondary coppice regrowth increased with an increase in the rate of glyphosate applied (0% < 0.6% < 1.2% < 1 .8%), especially when treated at either 1.0 or 1.5 m in height. Although the volume of the glyphosate used increased with increasing secondary coppice regrowth height (0.5 m < 1.0 m < 1.5 m) due to the larger foliar spraying area, there was little difference in total glyphosate used when comparing the same herbicide rate across the three different heights. The most cost-effective treatment was that where glyphosate was applied at 1.2% when the secondary coppice regrowth was 1-1.5 m. The third trial (also located in Zululand on Eucalyptus grandis x E. urophylla) was implemented to test the knowledge gained in trial two, thereby determinng coppice management regimes that would facilitate mechanised harvesting. In this trial, coppice shoots were reduced to one stem per stump in one thinning operation (coppice reduction heights of 3.5 m, 4.5 m and 6.5 m), with the impact of increased secondary coppice regrowth monitored together with the testing of different control methods. An additional control treatment was included (current best operating practice) with coppice shoots thinned to two stems per stump at shoot height of 3.5 m, and thereafter to original stocking at stem height of 6.5 m. Herbicide rate and timing of application was based on the results obtained in the second trial, with glyphosate applied at 1.2% when the secondary coppice regrowth reached a mean height of approximately 1 m. At the final measurement date, the diameter at breast height for all three coppice reduction height treatments (3.5 m, 4.5 m and 6.5 m) were significantly larger than the additional control treatment. This can be attributed to the allocation of resources to the remaining stem at an earlier age, resulting in a growth benefit. For stocking, the 6.5 m coppice reduction height was significantly higher compared to both the 3.5 m and 4.5 m coppice reduction treatments, while not significantly different from the additional control. In this trial, secondary coppice regrowth had no effect on tree growth. Due to the short duration of this trial, a longer trial period would be necessary to obtain a full understanding of the impacts of the various coppice reduction treatments, and the resulting secondary coppice regrowth influence on selected coppice growth if left untreated. As several previous studies have shown the importance of controlling secondary coppice regrowth, it is recommended not to view the results of this present trial in isolation. On the basis of the results of this research, it can be concluded that the control of coppice regrowth with herbicides is more effective than any of the manual removal treatments in terms of cost, with manual control requiring more follow-up control operations. Even though the manual removal of coppice regrowth had no influence on growth of the remaining stems or planted trees, the potential injury to labourers or growing stock is still of concern. Therefore, the use of herbicides for controlling coppice regrowth would be preferable. However, if reduced herbicide-use is a major criterion, then coppice regrowth can be controlled manually, although at a higher cost.

In this trial, coppice shoots were reduced to one stem per stump in one thinning operation (coppice reduction heights of 3.5 m, 4.5 m and 6.5 m), with the impact of increased secondary coppice regrowth monitored together with the testing of different control methods. An additional control treatment was included (current best operating practice) with coppice shoots thinned to two stems per stump at shoot height of 3.5 m, and thereafter to original stocking at stem height of 6.5 m. Herbicide rate and timing of application was based on the results obtained in the second trial, with glyphosate applied at 1.2% when the secondary coppice regrowth reached a mean height of approximately 1 m. At the final measurement date, the diameter at breast height for all three coppice reduction height treatments (3.5 m, 4.5 m and 6.5 m) were significantly larger than the additional control treatment. This can be attributed to the allocation of resources to the remaining stem at an earlier age, resulting in a growth benefit. For stocking, the 6.5 m coppice reduction height was significantly higher compared to both the 3.5 m and 4.5 m coppice reduction treatments, while not significantly different from the additional control. In this trial, secondary coppice regrowth had no effect on tree growth. Due to the short duration of this trial, a longer trial period would be necessary to obtain a full understanding of the impacts of the various coppice reduction treatments, and the resulting secondary coppice regrowth influence on selected coppice growth if left untreated. As several previous studies have shown the importance of controlling secondary coppice regrowth, it is recommended not to view the results of this present trial in isolation. On the basis of the results of this research, it can be concluded that the control of coppice regrowth with herbicides is more effective than any of the manual removal treatments in terms of cost, with manual control requiring more follow-up control operations. Even though the manual removal of coppice regrowth had no influence on growth of the remaining stems or planted trees, the potential injury to labourers or growing stock is still of concern. Therefore, the use of herbicides for controlling coppice regrowth would be preferable. However, if reduced herbicide-use is a major criterion, then coppice regrowth can be controlled manually, although at a higher cost.

- Description: It is an acknowledged fact that many novice programmers experience difficulty in the process of learning to program. One of the contributing factors to this difficulty is the Program Development Environment (PDE). Professional-PDEs are those developed specifically for professional programmers, but are often used by educational institutions in the instruction of programming. It has long been accepted that such environments are inappropriate in the instruction of programming due to unnecessary complexity and lack of support for novice programmers in the learning process. Numerous pedagogical-PDEs supporting the mechanics of programming have been developed in response to this. A review of literature, however, indicates that very limited empirical studies comparing pedagogical-PDEs and professional-PDEs have been conducted. The current study investigates whether there are measurable benefits to using a pedagogical-PDE supporting the mechanics of programming in the instruction of programming instead of a professional-PDE. A comparative study of this nature requires a representative pedagogical-PDE and representative professional-PDE be compared with one another. The first part of the current study determines a set of requirements that a pedagogical- PDE should adhere to based on literature. A set of representative features for a pedagogical-PDE is derived by examining the features of existing PDEs in conjunction with the set of requirements. Based on these features, a pedagogical-PDE, known as SimplifIDE, is developed that implements the representative set of features and that meets are the requirements for a pedagogical-PDE. The second part of the current study is the specification and administration of an empirical experiment in which SimplifIDE and Borland© DelphiTM are compared with one another. A holistic approach in determining the differences between the PDEs is taken and three main areas are examined, namely academic performance, perceptions and programming behavior.

- Description: The aim of this study was to establish reference data for the cervical spine’s dynamic force characteristics in a healthy adult urban South African population aged 19 to 69 years. The reference data was classified according to gender discriminate age categories. In total ten gender discriminate age categories, five male and five female, were created; 19 to 29, 30 to 39, 40 to 49, 50 to 59 and 60 to 69-year-olds. The force characteristics measured, analysed and used to generate reference data in stanine format were: absolute peak torque (P-), relative peak torque (P-/BW), peak power (Pow-), relative peak power (Pow-/BW), peak work (W-), relative peak work (W-/BW), torque acceleration energy (TAE-), maximal voluntary cervical muscle contraction range of motion (MVCR-), controlled full range of joint motion (CFR-), joint angle at peak torque (Jang@P-) and peak torque ratios for cervical flexion (-F), extension (-E), lateral flexion to the dominant (-LD) and non-dominant (-LN) sides. In addition biographic and anthropometric data was also collected. Data, grouped in the ten gender discriminate age categories were compared and statistically and practically significant differences were highlighted between the gender discriminate age categories. Inferential statistics used included ANOVA and Cohen’s d. A significance level of α = .05 was used in all inferential statistical analyses. Correlations between various anthropometric and isokinetic strength variables were also explored.

- Description: The Department of Education, as part of the public sector, employs educators in terms of the Employment of Educators Act (EEA),1 whereas the rest of the public servants are employed in terms of the Public Service Act (PSA). If an educator is absent for more than 14 consecutive days without the permission of the employer, the educator is deemed to be discharged according to section 14(1)(a). With regard to the rest of the public sector, a similar provision is put in place, where section 17(5)(a) provides for the discharge of a public officer who is absent from his / her duties without the permission of the Head of Department for a calendar month (31 days). Sometimes long absent periods are caused by personal circumstances of the employee which are unforeseen. If the employee reports for duty after the dismissal, section 14(2) of the EEA provides that, the employee may be reinstated by the employer on good cause shown, after a post-dismissal hearing. If an employee in the public sector is discharged based on these deeming provisions, the employment is terminated by the operation of the law and there is no dismissal. This means that the employer is not responsible for the termination, meaning than there exists no option to review the dismissal. The supreme law of the Republic of South Africa (RSA) is the Constitution of the Republic of South Africa (the Constitution).5 The question at hand is whether the deeming provision of section 14 of the EEA6 is constitutional. The Labour Relations Act (LRA) goes further by stipulating that every person has the right not to be unfairly dismissed, and not to be subjected to unfair labour practice.7 Section 23 of the Constitution provides that everyone has the right to fair labour practices. Furthermore, section 33 of the Constitution provides for fair administrative action. The question is whether these provisions, dealing with the dismissal of educators, limit the employee’s constitutional right to a fair labour practice.

- Description: Integrating Knowledge Management maturity with associated Continuous Improvement efforts in order to remain competitive, is absent in most Operational Excellence initiatives. Furthermore, the intertwined relationship of Continuous Improvement and work development becomes a crucial focus area for organisations that wish to establish a continuously evolving management system consisting of core values, methodologies and tools with the aim of creating more satisfied customers with less resources. The old industrial paradigm that focused on labour, capital, materials, and energy viewed technology and knowledge as external influences on production. This framework is now being challenged and a new trend is emerging. This trend seeks to transform the old industrial system to that of a knowledge-based which one can lead to innovation and hence economic advantage. Continuous Improvement as a concept has roots in many other fields, including social-technical system design, human relations progress and the discussion surrounding ‘lean manufacturing’. This study will focus on Continuous Improvement as a noun, referring to on the outcome of the process of a stream of emergent innovations. The primary objective of the study is to create a model that will present an organisation with a three-layer knowledge reference process grid, which will align and depict the surrounding business knowledge functions, knowledge-enabling processes and knowledge-manipulating processes aiming for enabling Operational Excellence. This study promotes the theory that the cognitive domain layer, functional domain layer and resources layer of an organisation can be increasingly stimulated by focusing effort through Continuous Improvement routines towards the associated inter-organisational knowledge processes sustaining Operational Excellence. The proposed model is structured to review, compare, evaluate and integrate existing Knowledge Management practices of ii an organisation within the context of clear definitions for important concepts of Knowledge Management. Additionally the model provides an assessment instrument for evaluating the organisation’s Knowledge Management maturity level. The study concerns itself with two concepts towards business value creation which will lead to increased Operational Excellence. Firstly, the maturity of Knowledge Management processes, and secondly the level of the organisation wide process of focused and continuous incremental improvement namely, Continuous Improvement. A case study with PriceWaterhouseCoopers was concluded and an on-line Internet survey was used with a stratified sample from knowledge workers to test the factors from both a Knowledge Management and Continuous Improvement perspective. These factors were verified by means of a hypotheses network, describing in a structured and descriptive way, the importance of Knowledge Management and Continuous Improvement collectively on sustainable Operational Excellence as an integral development of Operational Excellence. With respect to Knowledge Management practices, the hypothesis network proposed at least three domains, which of knowledge generation, knowledge mobilisation and knowledge application as important input to the proposed process grid of knowledge development and associated layer elements. From a Continuous Improvement principles perspective it is apparent that elements from Continuous Improvement routines and Continuous Improvement characteristics are associated with the organisation Continuous Improvement ability. These findings are also a result of the deliberate design of processes, tools, structures and environments with the intent to increase, renew, share or improve the use of knowledge represented in any of the three elements for structural, human and social of intellectual capital. The proposed model combines the framework of the Boyd cycle as it is conceptualized as self-assessment activities, for it becomes possible to use them as basis of a self-assessment with sense making navigational properties across iii the proposed knowledge process grid for the model. The model will facilitate the concept of a three-layer knowledge reference process grid, which represents the main components of the knowledge processes within the cognitive domain layer, functional layer and resources layer of an organisation. The proposed model will deliver a single value that co-exists with the Knowledge Management maturity level and Continuous Improvement readiness index rating attained. Logical relationships to dynamic, evolving and flexible enabling Knowledge Management practices for each layer of the proposed three-layer knowledge reference process grid will be integrated as output of the proposed model. The research has limitations as Knowledge Management practices were measured using a subjective norm scale. It is suggested that a more comprehensive measure of Knowledge Management maturity processes may be needed to represent this construct. The complexity of the proposed model and the number of associated variables included in the results need further confirmation using possible multiple samples and additional measures of Knowledge Management maturity and Continuous Improvement readiness elements. The benefit of the proposed model as a practical Operational Excellence tool is to overcome the perceived gap of implementing Knowledge Management practices and Continuous Improvement principles collectively to deliver and sustain Operational Excellence.

- Description: The research shows the critical success factors when implementing information security projects. Many Information security projects in the past have not been successful because these factors were not identified and emphasised effectively. By identifying these factors the research basically presents a model by which information security projects can be executed with guaranteed success. The factors identified during the study cover the following streams: top management commitment as a factor of success; accountability as a factor of success; responsibility as a factor of success; awareness as a factor of success and an information security policy as a factor of success. For the empirical study, a physical questionnaire was administrated to a pool of experts in project management and information security. The study consisted of 60 participants who were verified to have minimum requirements core for questionnaire completion. The questionnaire requested for biological information of the participants and their perceived relations (based on their experience) between project success versus accountability, information security project success versus responsibilities, information security project success versus training & awareness, information security project success versus top management commitment and information security project success versus information security policy. The participants’ responses were structured according to a Likert-type scale. Participants had to indicate the extent to which they agreed with each of the statements in the questionnaire. The responses obtained from the survey were presented and analysed. The researcher observed in this study that information security projects are so specific that critical success factors need to be emphasised from project inception. With the identified critical success factors, the researcher recommends that a project methodology be structured to include these factors so that there is a standard in running information security projects successfully. The researcher also identified that amongst the critical success factors identified, there are some that need to be emphasised more than the others due to their level of importance in such projects.

- Description: The World Health Organisation (WHO) declared tuberculosis (TB) a global emergency, and this infectious disease remains a health threat by being the leading cause of death amongst adults (Naidoo, Dick & Cooper, 2008:55). In 2005, South Africa was ranked seventh in the world for having the highest TB rate and the lowest TB success rate in the world. As a professional nurse involved in the tuberculosis programme at a clinic in the Nelson Mandela Bay Municipality at local government level for approximately three years, the researcher observed that the morale of professional nurses who provide TB services appeared to be low. They also appeared to be frustrated because they feel that they are not winning the battle with regard to the TB epidemic in their communities irrespective of their efforts to try and curb the spread of the disease. The extent of the workload per person also appeared to add to the low morale and frustration of the professional nurses rendering TB health services because they feel that they are unable to manage everything. The objectives of the study were therefore to explore and describe how professional nurses experienced the management of health services being rendered to TB patients in Sub district B of the Nelson Mandela Bay Municipality (NMBM) in order to make recommendations that could be used by the district manager to address the research findings. The research study was based on a qualitative, explorative, descriptive and contextual research design. The research population consisted of all professional nurses who worked in the TB services of Sub district B. Non-probability, purposive sampling was used to select the participants for the study. Seven in-depth and three follow-up interviews were conducted before data saturation was achieved. The data gathered during the interview process by the researcher were transcribed and coded by an independent coder using Tech’s model for data analysis. Ethical considerations were adhered to throughout the research study. The aspect of trustworthiness according to Guba’s model was implemented in the research study and included credibility, applicability, consistency and neutrality. iii One theme, two sub themes and categories were identified relating to the diverse experiences expressed by the participants relating to the management of health services being rendered to TB patients. The experiences expressed by the professional nurses included both negative and positive experiences. The negative experiences expressed by the participants were for example, a lack of resources as hampering adequate service delivery, a concern regarding the number of staff contracting TB due to a lack of infection control measures, a difference in conditions of service between the two local authorities and the DOTS supporters as being a threat to patient confidentiality. The positive experiences expressed by the participants included experiences relating to job satisfaction in rendering TB health services, the DOTS supporters as being supportive to the staff, the TB meetings serving as an appropriate platform for problem solving and the audits conducted by managers as being remedial. The study concludes with recommendations made with regard to the areas of nursing practice, education and research.

The study concludes with recommendations made with regard to the areas of nursing practice, education and research.

- Description: With English as the medium of academic exchange, Chinese students are the largest single overseas student group in the English speaking countries (2010). Relative to the outbound education market of other countries, the Chinese education market is large, and it is currently receiving much attention globally. Not only is South Africa one of countries where English is spoken, it has relatively speaking, low study fees and easily-accessed visas compared with countries in Europe and the United States. Therefore, South African universities have a virtually unlimited potential for receiving Chinese students. For South African education providers, particularly NMMU as the host university for the research in question, in order to render the expected education quality and to cater for the Chinese education market effectively, it is of utmost importance that the institutions have a clear understanding of Chinese students’ expectations as well as their actual academic experiences (in the broadest context) when studying at this university. The above is closely linked to the expected educational quality, the actual educational delivery as experienced by Chinese students, as well as the levels of satisfaction they experience as students at NMMU. The purpose of this research project is twofold. Firstly, it aims to construct a theoretical model showing the variables and relationships pertaining to expected and actual educational delivery as experienced by Chinese students. Having assessed the perceptions of the respondents based on the findings, another purpose is to design appropriate educational marketing strategies suitable to address the academic needs and expectations of Chinese students in the broadest context. By designing appropriate education strategies, the potential to develop the Chinese education market in South Africa will be enhanced. Given the purpose and nature of the research in question, methodological triangulation strategies were used. A Likert seven-point scale research instrument was developed and administered. Due to the limited number of respondents (n=61), the Likert scale instrument was further subjected to enrich the data by means of face-to-face interviews with 61 Chinese students (respondents), who shared their perceptions on the expectations and actual experiences of NMMU academic programme quality encounters. By following the methodological triangulation strategies, the validity of the findings is enhanced. The phenomenological dimension of the research was conducted according to guidelines as documented in secondary sources. The findings of the matched pair t-tests indicated that significant statistical differences do exist between the ‘expectations’ and ‘actual experiences’ of Chinese students’ perceived academic programme quality. Sufficient evidence is available at the 95 percent level of significance to support the hypothesis H1, namely: “There are differences between Chinese students’ ‘expected’ and ‘perceived’ academic programme quality (actual experience) of NMMU”. Besides the matched pair t-tests, further statistical analyses were performed by means of calculating Cohen’s ‘d’ values and relative percentage ratings to assess the magnitude of the “gap” between expectations and actual experiences of Chinese students studying at NMMU. The findings revealed that the Chinese students were not completely satisfied with their actual experiences when studying at NMMU. The above statistical findings were endorsed by the qualitative findings. Three sets of conclusions and recommendations were identified for this research. Firstly, conclusions emanating from secondary sources on service quality and students’ satisfaction literature were provided, such that students satisfaction is seen more as a psychological state which reveals an overall feeling of the students’ purchase and consumption experience. Secondly, the conclusions linked to the empirical findings revealed significant statistical differences between the expectations and perceptions (actual experiences) of Chinese students’ perceived academic programme quality. Finally, recommendations on relevant NMMU educational marketing objectives/ strategies can be grouped into four domains: - To build a customer-led education business which adheres to the principles of true marketing orientation with the focus on Chinese students. To achieve this objective a high level of understanding of Chinese students’ specific needs and wants when studying at NMMU is of utmost importance. The effective marketing positioning of NMMU can render leverage benefits to themselves and their clientele. - Findings from the biographic data analyses are significant to the positioning strategies and market segmentation strategies of NMMU. - The decision on a proper positioning strategy entails the choice of target market segments, which will determine where and how the education business competes and its choice of differential advantages. - The South African education providers should have appropriate educational brands to entice the Chinese students’ support.

- Description: This study sought to empirically investigate the existence of calendar effects and market anomalies on the JSE using monthly and daily closing prices of the ALSI, Top 40, Mid Cap and Small Cap index; as well as, daily closing prices on the Value, Growth and Dividend Plus index during the sample period 2002 – 2013. The anomalies analysed are the January effect, the weekend effect, the size effect, the value effect, and the dividend yield effect. The empirical analysis uses a number of MSAR with a different number of regimes and lag orders. The results from the investigation of the January effect show the non-existence of the January effect and the value effect on the JSE during the periods 2002 – 2013 and 2004 – 2013, respectively. However, the weekend effect was found significant in the Mid Cap and the Small Cap index, and the size effect was also found significant during the same period 2002 - 2013. Finally the results from a Granger causality test concluded that there is a relationship between the returns on the Dividend Plus index and the ALSI, effectively proving the existence of the dividend yield effect on the JSE between 2006 and 2013. Additionally, the anomalies found imply the opportunity for investors to make returns above buy-and-hold.
