- Description: This paper seeks to bring clarity to a number of issues that arise from a process resulting from the unilateral variation of terms and conditions of employment and the conflict management and dispute resolution processes. The variation of employment terms particularly when it is driven by one party to the employment relationship can cause instability, insecurity, confusion and uncertainty to the parties involved. The nature of work is not constant and therefore changes are inevitable. This then has an effect of bringing disorder not only to the employer-employee relationship but also to the labour relations balance. In many instances and depending on whether it is the employer or employee who propagates the changes, the reasons to alter the conditions are different. Employers usually cite operational or economic reasons that are meant for the survival of the business as the need to make the changes. From the employees’ side the changes are necessitated by reasons aimed at a move from protecting the favourable employment conditions already acquired to improving them or attaining more. In the event that the parties to the employment relationship do not agree to the changes proposed and implemented, a dispute usually arises. This results from the failure of a consultation process, negotiations, persuasion or collective bargaining in general. In essence such a dispute arises from absence of consent to the changes. The failure of a bargaining system requires the process to assume a new nature. The dispute resolution systems and the conflict management systems follow as both the appropriate and necessary steps. The bargaining power together with the intervention of the third party is at the centre of this phase. The parties, depending on the nature of the dispute, the conditions that iv are changed and who are affected by the changes, have choices on what dispute resolution mechanisms to employ. The choice made has a huge impact on both the outcome required in the form of recourse, how the dispute will be resolved or how the conflict will be managed. There is legislative intervention with regards to the resolution of the conflictual scenarios that arise from disputes on unilateral variation of terms and conditions of employment. There are also non-statutory measures available to the parties. The choices are vast as to when can the variation take place, the reasons for the changes, the parties involved, the possible dispute resolution mechanisms, what can be varied and whether the unilateral implementation can be viewed as fair.

- Description: Special needs education has always provided special challenges to school administrators, policy makers and teachers. The world-wide move towards inclusive education as an alternative to exclusive education or casual mainstreaming has resulted in significant developments in Namibia in the past decade. Global educational reforms have focused on education for all as well as inclusive education and Namibia is signatory to several conventions and declarations in this regard. Research in this field has largely focused on the role of the inclusive teacher, and of course the special needs of the learners. Little or no attention has been paid to possible managerial and organisational challenges which accompany the move to inclusive education. This thesis seeks to critically investigate the managerial implications of inclusive education. The focal point of this research is to gain a clear understanding of the managerial implications in an inclusive school for learners with visual impairment, chiefly through an exploration of the experiences of management members of the inclusive process. The research is located within a qualitative research paradigm, which is subsumed by a phenomenological model. The data gathered through in-depth interviews include many anecdotal accounts that provide insight into the ways respondents reacted to experiences at the inclusive school. The main findings of the research are highlighted and discussed. Recommendations arising from a critical analysis of these main findings are presented.

- Description: This is a qualitative study exploring the use of workshop theatre in post-apartheid South Africa, with the objective of making a contribution to the knowledge-base regarding its use in current times. Workshop theatre is changing in response to a new socio-political reality and emerging trends in theatre practice. The case study, of developing a play on Oystercatchers with a Grahamstown group of artists, revealed the difficulties and challenges of using workshop theatre in this dynamic context. Data collection included a focus group, observation, reflective discussion and in-depth interviews that were analysed in relation to available literature on workshop theatre in apartheid and post-apartheid South Africa. It is proposed that workshop theatre has continued relevance in post -apartheid South Africa. The process of creating workshop theatre with diverse artists has great potential to transform relationships, address issues of personal identity and to provide an underlying purpose to a workshop theatre -making context.

- Description: The key aspect to stimulating economic and individual growth in the workplace has been shown in numerous case studies to be the removal of discrimination. Affirmative Action looks at dealing with, and making amends for past injustices, as well as moving towards equal employment opportunities in a constructive manner. It is about recognizing that people are inherently different whilst trying to achieve a “colour – blind” society. The Employment Equity Act No. 55 of 1998 was put in place by Government to facilitate the implementation of fair workplace practices, which will correct the imbalances of the past as well as creating a workforce, which reflects the demographics of South Africa. The inequalities in employment patterns and practices with respect to access to employment, training, promotion and equitable remuneration especially for black people, women and people with disabilities are addressed in the said Act. The Employment Equity Act is quite specific about the minimum requirements of an organisation’s Employment Equity Plan, which make it easy to identify what progress is being made towards ending discrimination in the workplace. The minimum penalty for contravening the Employment Equity Act is R500 000 and the maximum is R900 000. The question arises as to whether South African organisations are merely implementing Employment Equity policies to adhere to the basic requirements and deadlines of the Act. Or, are these policies genuinely based on commitment to the principles of equality and equal opportunity for all in the workplace. Calsonic Kansei South Africa has put into place various training and succession plans, which will help to achieve the organizational goal of being more equitable in terms of the Employment Equity Act. Employment agency databases have also been analysed to determine the availability of suitably qualified Affirmative Action employees. In this paper the writer will investigate the progress that Calsonic Kansei South Africa has made towards achieving Employment Equity in relation to other organisations within the same industry.

- Description: Cerebral ischaemia, traumatic injury to the brain, inflammatory neurological disorders and HIV infections are amongst the most prevalent causes of neurodegeneration. Neuroprotective strategies are usually to limit the progressive secondary injury that generally occurs, thus limiting overall tissue damage. Neuroprotective strategies are usually to limit the progressive secondary injury that generally occurs, thus limiting overall tissue damage. Sodium channel blockers have been often used for this matter as they prevent the cascade of events culminating in free radical generation and eventually neuronal apoptosis. Newer compounds, such as antiperoxidants and free radical scavengers, show encouraging experimental results, but their clinical use is still very limited. Phenytoin being a popular drug in the treatment of epilepsy has also been used as a neuroprotectant during certain neurological emergencies and in pharmacological prophylaxis of post-traumatic epilepsy. Furthermore this agent functions by prolonging inactivation of voltage gated sodium channels. In these sets of experiment the neuroprotective properties of phenytoin were examined. The histological study revealed that phenytoin confers protection to the CA1 and CA3 regions of the hippocampus under the insult of QUIN. Cells maintain their characteristic shape and minimal tissue necrosis occurs in the presence of this agent. The in vitro effect of this antiepileptic drug on free radicals generation shows that phenytoin does not reduce or prevent the formation of these reactive species. Lipid peroxidation was induced using QUIN and iron (II), two known neurotoxins. The study reveals that only lipid peroxidation induced using iron (II) is reduced by phenytoin. These experiments were carried out in whole rat brain homogenate. These studies show that phenytoin possesses poor free radical scavenging properties. However, the dose-related reduction of iron-induced lipid peroxidation allows for speculation that phenytoin interacts with iron in order to reduce neuronal damage. Metal binding studies were performed using UV, IR and electrochemical analysis to examine the interaction of phenytoin with iron (II) and iron (III). Phenytoin, when added to iron (II) in solution, first oxidises the latter to iron (III) and maintains it in that form. A shift in the peak was observed in the UV spectrum when iron was added to phenytoin. Moreover, electrochemical studies indicate that the interaction between the metal and the ligand is very weak. The IR analysis it shows that phenytoin may be coordinating with iron through the Nitrogen atom on the phenytoin molecule. These studies show that phenytoin maintains iron in its oxidised form, which is a good property to possess as a neuroprotectants. Pineal organ culture showed that phenytoin does not increase melatonin production but slightly and non-significantly reduces the levels of this pineal hormone. However there is a significant rise in precursor NAS levels. As melatonin is known to possess antioxidant and free radical scavenging properties, this could mean that this drug can cause the CNS to become more susceptible to attacks by reactive oxygen species.

- Description: During this research, an attempt was made to gain an understanding of management and their employees' perceptions regarding functional and numerical flexibility practices within South African organisations. To achieve this, twenty-six people, comprising of a variability of positions within the organisation, were interviewed in the region of the Western Cape. It was found that, although extensive research on the two forms of flexibility have been globally conducted, South African literature, particularly on the part of numerical flexibility, is limited. It is thus believed that this study will present a valuable basis to pursue in further research. Literature that was consulted was found to be supportive of the theoretical notion that South African organisations, in order to be globally competitive, have had to restructure and redefine themselves by ensuring that they make the most efficient and effective use of their human resources. The study found that whilst functional flexibility practices benefit employees in that they experienced increased job satisfaction and job mobility, it was the area of numerical flexibility which raised many dissatisfactions, including those of immense job insecurity and remuneration, both financial and otherwise. The study findings suggest a need for a more comprehensive and employee integrated approach by combining organisational with individual oriented initiatives, and ensuring the trade union's involvement in all facets of functional and numerical flexibility initiatives. The thesis ends with recommendations of various strategies for addressing the concerns of management, employees and the trade union in order to ensure full and proper utilisation of human resources so that the end product, namely job satisfaction, leads to organisational success.

- Description: To avoid environmental pressure from water authorities, specifically regarding nitrogen and sulfate limits in tannery wastewater, modifications to existing deliming processes have been made. Conventional ammonium salt deliming methods contribute to Total Kjeldahl Nitrogen values in the region of 0.5 – 1.0g/L (33-67% of total TKN). Sulfate levels are increased with the use of organic deliming and ammonium sulfate deliming to the extent of 0.9g/L (27% of total sulfate). To understand the dynamics and kinetics of carbon dioxide equilibrium, the movement of carbon dioxide into deliming water, through carbonic acid, bicarbonate and ultimately into carbonates at liming or early deliming pH was studied. It was shown in this study that effective lime removal, at optimum conditions, resulted in fully delimed pelts at highly comparable quality and times compared to conventional ammonium salt deliming

- Description: The rapidly increasing competitiveness within the fast-moving consumer goods (FMCG) market compels an organisation within this market to not only entice consumers to purchase the organisation’s brand, but also to keep these consumers purchasing the brand. It is therefore essential that an organisation creates and maintains loyalty among consumers towards its brand. The objective of the research was to find out what strategies an organisation could implement to achieve and sustain loyalty from current and prospective consumers towards its brand in a highly competitive, FMCG market. The main areas of focus were as follows: Establishing the basis on which consumers differentiate between homogenous products. Determining what strategies an organisation could utilise to ensure that consumers will differentiate its brand from those of competitors. Obtaining relevant information to find out what variables motivate consumers to be brand loyal within the FMCG market. Ascertaining how an organisation could build a brand. Determining how an organisation could maintain brand loyalty from its existing consumers. The research included a study of relevant literature and an empirical study. The aim of the literature study was to obtain a solid base of information and opinions regarding the concepts of brands and building brand loyalty. Making use of structured questionnaires and through performing personal interviews, the empirical study consisted of two aspects. The one aspect was a brand loyalty survey conducted among 303 respondents, and the second aspect was a brand loyalty survey conducted with nine owners or marketers of leading brands. The following were the major findings of the research: Relying on being a leader in price and quality is not enough to ensure that a consumer would continue purchasing an organisation’s brand. A brand is an experience and in order for a consumer to become loyal towards a brand, the consumer should have a host of positive thoughts regarding past experience with the brand. It is essential that organisations within the FMCG market proactively develop and implement strategies aimed at creating and maintaining loyalty towards their brands.

- Description: The chokka squid, Loligo vulgaris reynaudii, is a commercially important species supporting a large, high-value export fishery for South Africa. This study reviewed its population dynamics and reproductive biology. Biological information collected on biannual research cruises from September 1986 to April 1999 on the Agulhas Bank as well as information from commercial vessels operating in the inshore environment collected between April 1988 and July 1989 and again between June 1999 and May 2000 were analysed. Size ranges of juveniles, subadults and adults were calculated and used to determine seasonal distribution and abundance patterns. Based on Gonadosomatic Indices (GSI) and percentages of mature squid in each month, two peak reproductive seasons in summer and winter were identified although mature squid were present all year round. Seasonal peaks in sex ratio were also apparent with males outnumbering females by up to 4:1 in the peak-breeding season. The size at which squid matured, demonstrated both spatial and temporal patterns. Squid caught in spring matured at a smaller size than squid caught in autumn and at successively smaller sizes from west to east across the Agulhas Bank. Size at maturity was highly variable especially in males where “sneaker males” were evident in both seasons. Length-to-weight linear regression revealed significant differences between maturity stages and between sexes. Females demonstrated steeper length-to-weight regression slopes than males in the peak-breeding seasons. Aspects of squid biology pertinent to fishery management were highlighted as well as potential areas where research should be directed in order to develop future stock assessment models.

- Description: In introducing the four novels under discussion as a “History of Confession”, this study explores the resistance to the dominant discourse of ‘history’ offered by the sustained confessions of individuals. In examining Coetzee’s oeuvre it is possible to delineate the outline of a dialogue between cynicism and grace, and the effects of these on the process of confession in each of the works Chapter One, dealing with Age of Iron, draws on Levinas’ theory of ‘the Other’ in order to elucidate the role played by the interlocutor or confessor in the process of confession.The recognition of the passage of the self through the Other is integral to the attainment of a state of grace, without which confession cannot be brought to an end The countermanding claims of the writer's will-to-write and duty to society are illuminated as a source of cynicism which overwhelms the intervention of grace. The Master of Petersburg, discussed in Chapter Two, is a confession of the guilt and despair faced by the writer who sacrifices his soul to answer the urge to write. Chapter Three, which examines Coetzee’s excursion into autobiography, represents a continuation of the confessional trend. The distance between the narrator and protagonist of Boyhood illustrates the convolutions of self-deception in the process of confession. The chapter which deals with Disgrace identifies a new trend in Coetzee’s writing:the concern with animals. Levinas’ theory, which identifies the encounter with the Other as necessary to precipitate an intervention of grace, is again useful in explaining how Coetzee has postulated the unassimilable otherness of animals as primary to human ethical development. This chapter also concludes that Disgrace represents a high point in the recovery of both grace and agency in Coetzee’s oeuvre.The concluding chapter suggests that the accumulation of meanings to the term ‘grace’enables its definition as a semi-religious abstraction. Coetzee suggests that belief in its existence has the power to affect interactions on the physical plane, especially those between the self and the Other.

- Description: This thesis proposes a technique to determine and improve the performance of a sensorless speed estimator for an induction motor based on Motor Current Signature Analysis (MCSA). The theoretical concepts underlying the parameter based observer are developed first and then the model of the observer is built using Simulink. The observer is developed based on Model Reference Adaptive System (MRAS). The dynamic performance of the observer and its behavior due to variation of machine parameters is studied. The error in speed estimated using this observer is shown and the ability of MCSA to retune the rotor speed from the stator current spectrum. The spectrum estimation technique has been implemented using a software routine in Matlab. Both the observer and MCSA techniques were implemented practically on an induction motor. The performance of the combined sensorless speed estimation system was tested and verified.

- Description: The research problem addressed in this study was to identify guidelines to improve business processes that will enhance the ability of Small, Medium, and Micro Enterprises (SMME’s) to be able to operate competitively in local and global markets. Reengineering of business processes (BPR) is necessary because of internal factors such as increasing global competition, increasing domestic competition, new technologies, industry overcapacity, shrinking markets and increasing pressure from suppliers. There are also various external factors that influence the necessity to reengineer business processes. These factors include increasing cost structure, declining profitability, declining sales, low productivity, inadequate employee skills and less efficiency in operations. In order to identify guidelines that will enhance SMME’s performance, questionnaires with relevant questions were used . The findings of the literature survey clearly highlights the specific areas where attention is required for improvements.

Data was obtained through use of pre - coded self administered questionnaires which were employed to 50 domestic women who are working in East London and its suburbs and have children under the age of 16 years. Semi-structured interviews were tape recorded and transcribed and the analysis process looked at general trends where qualitative data was obtained. Quantitative data was tabulated in frequency tables and interpreted by means of graphs. The study is pioneering efforts in the Eastern Cape and South Africa in general as well as setting a way forward for further exploration of this subject. It is hoped that the study will make a worthwhile contribution and bring upfront valuable information that could be used when addressing issues of domestic workers. The study also indirectly challenges those professions and disciplines who have been advocating on behalf of domestic workers to mobilize these workers towards taking part in the uplifting of their standards and to fInish up the good work they had already started until their aims have been achieved. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This thesis aims to allow the meanings engendered by various black hairstyle choices to emerge as discursive texts with which to further explore issues of black identity in post-apartheid South Africa. It seeks to identify what, if any, new discursive spaces and possibilities are operational in the post-apartheid capitalist context, and how identities are moulded by, and in tum, influence these possibilities. Operating within a discourse analytic approach, this research did not intend to establish fixed and generalisable notions of identity, but by unpacking the discursive baggage attached to historically loaded subjectivities it is concerned with reflecting identity as an ongoing and reflexive project. Entailing a diverse selection of texts, the analysis includes self-generated texts (stemming from interviews, a focus group and participant observation), and public domain texts (stemming from online and print media articles). Chapters 5 - 9 constitute the textual analysis. Using a consumer hair care product as a text, chapter 5 serves as an introduction to discourses surrounding black hair as a variously constructed object. This focus is concerned, more specifically, with the construction of black hair as a 'natural' object in chapter 6. Chapter 7 examines black hair gemonies and the " problematic classification and de/classification of class and consumer identities. Discourses pertaining to the construction and positioning of gendered and sexual subjectivities are explored in chapter 8. Finally, chapter 9 is concerned with the operations of discourses as they function to construct essentialised or hybrid conceptions of identity. The implications for black identity construction in post-apartheid South Africa are discussed in chapter 10 alongside a deconstruction of the research method and researcher positioning.

- Description: The South African hake resource faces divergent fishing pressures and management issues. Although the resource consists of two species, management was simplified because the resource was only subject to trawl effort and because of the similarity in population parameters, single species assessment models could be adopted. The impact of trawling on the stock is considered to be well understood and the resource has shown recovery since exclusion of foreign vessels. The 1990s were punctuated by major political change and the need for transformation has resulted in an expansion of the number of fishing rights holders. Longlining has been reintroduced and there is no clear understanding of how the combined fishing pressures will affect the population structure of either Merluccius capensis or M. paradoxus. Information is vital to successful management. Fisheries are complex and intricate, and at times appear impossible to control or monitor. An integrated information system provides easily understood graphical explanations of complex issues. This thesis assessed the dynamics of the trawl and longline fisheries between 1994 and 1999 using a geographical information system (GIS). The accessability of a GIS incorporates the needs of scientists, managers and fishing communities. The simple GIS developed in this study revealed shifts in effort, facilitated the calculation of spatially precise catches and biomasses and highlighted the inadequacy of current sampling coverage. Trawlers were shown to fish the same areas consistently during the years investigated, with highest fishing intensity and average CPUE achieved at depths between 300 and 500m. Analysis of the longline sector revealed several similarities to the trawl sector, fishing intensity was highest between 301 and 500m, suggesting that both sectors face a "friction of distance" dilemma. The distribution and abundance of hake, in particular the exploitable proportion of the population, was determined by a combination of depth and substrate type. The selectivity patterns of trawlers and longliners were briefly investigated with the results illustrating that gear selectivity of the M. capensis stock was depth dependent. The deeper fishing occurred, the larger the length-at-selection. As a result, the M. capensis parental stock faces unprecedented fishing pressure. In the absence of reliable species-specific catch data, logistic and linear regression models were developed to split the hake catch into its respective species components. Large discrepancies between the predicted M. capensis catch for the two models were noted. Regression estimates constructed at a finer spatial scale may provide a better fit than the current depth logistic employed by Marine and Coastal Management. A first attempt at assessing the M. capensis resource on the West Coast using an age-structured production model was presented. It was found that a lengthy and accurate M. capensis catch series is required before it is possible to successfully model the dynamics of the stock. It is necessary to incorporate finer spatial detail in the collation of catch data and collection of sampling data. It would be unadvisable to assume that the stock is stable or recovering. The implications of a size/sex relationship must be investigated and properly appraised.

- Description: This thesis deals with constitutional law and other legal subjects such as Jurisprudence and Judicial Review. One constitution is distinguishable from another by its own provisions. These provisions are usually referred to as either the basic characteristics or features of the particular constitution and these are invariably derived from the basic political philosophy and constitutional arrangements of the particular country. A coup affects these characteristics in different ways. Some automatically disappear as being incompatible with the revolution; some are modified, others are strengthened. The usurpers may choose to set aside the constitution completely and replace it with another, or amend it to suit the new situation, or rule without any constitution. This often happens amidst the rattle of weapons and the whirr of military engines in and around the capital of a given country on that awesome occasion. This thesis sets out to examine the legal aspects of a coup d’ etat. The thesis is divided into six broad sections. Part one will deal with the theoretical background. I shall discuss an overview of Kelsen’s pure theory of law. The second part deals with the scope of its application in revolutionary situations and will also touch upon the reason behind the Kelsen’s theory as shown by decided cases from country to country. The third part deals with the essence as well as the significance of the doctrine of necessity to validate unconstitutional acts in the case of a coup d’ etat. This discussion is to pave the way for the fourth part which is to explore the position of judges who took oath of office under the old constitution. I am to explain their position after a coup d’ etat. The fifth part forms the gist of my research. I shall examine the effect of a coup d’ etat on traditional constitutional concepts such as fundamental rights, separation of powers, rule of law and judicial review in the military regime. The sixth part will deal with African experience. I shall include recommendations and conclusions drawn from the Lesotho and Uganda experiences.

- Description: The focus of this study is on assessment in an Outcomes Based Education environment. The question arises as to how assessment of Entrepreneurship and Business Management-N4 can be changed to suit an Outcomes Based Education approach. Action research was used as the research methodology and the findings were reported as case studies. A sample of three colleges in the Eastern Cape was chosen to take part in the study. Only two modules of the Entrepreneurship and Business Management-N4 syllabus were adapted to suit an Outcomes Based Education approach, as the students still had to write the normal external examination at the end of the semester as required by the Department of Education. In the first two cycles the participants implemented Outcomes Based Education in the classroom using only the resources available at the college for the old education system. During the third cycle the researcher implemented Outcomes Based Education in the classroom under the same circumstances, but with the advantage that the researcher benefited from the reflections of the first two cycles. In order for assessment to meet the requirements of an Outcomes Based Education approach, it was necessary to change teaching practices as well. Important aspects such as group work, new assessment methods, the role of resource materials and the training of lecturers were included in the study. At the end of the third cycle a model for the assessment of Entrepreneurship and Business Management-N4 was developed. Recommendations on aspects such as students, lecturers, resources and assessment were made.

- Description: This thesis is a case study analysis of the dream one radio station had about creating something new and unique on the Internet. RadioSonderGrense (RSG), an Afrikaans South African radio station, saw opportunities for themselves as a radio station on the Internet and put enormous resources and man-power into their venture. Their vision of what the Internet could bring to their radio station, and what they could bring to a website set the ground for creative and innovative thought. This dissertation is an examination of whether the Internet lived up to the expectations RSG had for it, and whether they were able to use their resources (in terms of their audience, their advertisers and the uniqueness of radio) to create something new and never seen before. The foremost aim of this dissertation is to shed some light onto the up-to-now under researched area of why radio stations have begun to develop on the Internet. Through the analysis of RSG, their comes to this subject some new thoughts and ideas about the convergence of these two mediums. RSG, and radio in general, are examined historically, practically and in comparison to the Internet. This is done in order to fully grasp the project that RSG had set for themselves and to realize where they had come from and where they hoped to go. It is argued that although RSG had hoped for great things, their innovative thought was not enough to guarantee them their dreams. They were not able to fully utilize the resources available to them in combination with what the Internet could offer them to fulfill the expectations they had for themselves. The foremost conclusion is that although RSG were able to envisage what the Internet could add to the radio station, they fell short of giving their listeners, users and advertisers a tool which could make the RSG website truly unique. Their website gives the user some interesting and useful applications, but it does not make full use of what the Internet and radio together could create.

- Description: In many organisations, project management is no longer a separately identified function, but is entrenched in the overall management of the business. The typical project management environment has become multi-project. Most of the project decisions require consideration of schedule, resource and cost concerns on other project work, necessitating the review and evaluation of multi-project data. Resource management is at least as important as schedule (time) management. Functional managers, supporting multiple projects with shared and limited resources, need to know the demands on their resources and the impact of new project loads and changing priorities. This means that the effectiveness of project management is not only influenced by the function itself, but it permeates throughout the entire organisation, for which the overriding goal is to survive and prosper in a competitive environment. The research problem of this study is to assess how effective project management practices in the South African communications’ industry are, by using Telkom SA as the selected target group. The research method employed was to first identify the best practices of project management, by focusing on generally accepted standards and practices, that is those which are particularly effective in helping an organisation to achieve its objectives. The Project Management Body of Knowledge (PMBOK®) which is considered to be the international standard for project management, was used as the framework for identifying the best practices. The identified best practices were used as an assessment tool to determine to what extent these practices are applied in Telkom SA.
