- Description: Organisations are continuously searching for ways to increase their competitiveness as a means to survive in the global economy. More recently approaches have focused on the role that people perform in bringing about competitive advantage. Research indicates that engaged employees contribute vastly to the financial bottom-line of the organisation (see section 3.2.2). The research problem in this study was to identify strategies that organisations can use to engage their employees. To achieve this objective a theoretical employee engagement model was presented. The presentation of the theoretical model consisted of the following sub-processes: § Firstly, a literature survey was conducted to determine the underlying drivers/constructs of employee engagement. Abstract iii § The second comprised surveying the literature dealing specifically with approaches for measuring employee engagement. § Thirdly, the literature was surveyed to identify strategies and models used by organisations for engaging employees. The theoretical employee engagement model served as a basis for the compilation of the survey questionnaire that determined the extent to which human resource practitioners and line managers agree with the theoretical model developed in this study. The questionnaire was administered to a random sample of individuals employed in the automotive cluster in the Nelson Mandela Metropolitan Municipality and the Buffalo City Metropole. The empirical results obtained from the survey indicated that respondents strongly concurred with the theoretical employee engagement model presented in the study. These results were included in the theoretical model, which lead to the development of the integrated organisational employee engagement model. The model comprises of four interrelated categories that all contribute to enhancing employees’ engagement. These categories are organisational leadership, organisational culture, organisational strategies and the manager’s role. From the literature survey and the study it became clear that the role of the manager, had the most significant impact on employee engagement of all the categories. In addition, the integrated organisational employee engagement model can be used by organisations as an applied strategy for the measurement of employee engagement. The main findings from this research are that 60 per cent of organisations that participated in the empirical study had implemented strategies to engage their employees. However, the majority of organisations reporting not having an engagement strategy were among organisations that employed less than 700 employees (smaller organisations). The study also highlighted certain variables that required special attention, especially when implementing employee engagement within the South African context. South African companies as compared to their overseas counterparts, rated organisational engagement variables such as remuneration, benefits and gain sharing lower. A further variable that was identified by the study requiring special attention was, ‘senior management shows a sincere interest in employees’ well-being’. A final point emanating from the study is that the implementation of employee engagement, as a strategy to enhance organisational competitiveness, must be viewed as a continuous process. Organisations should prior, to the implementation of an employee engagement strategy, consider whether they are prepared to share engagement results, take corrective action commensurate with the results and deal with employee expectations that may be incurred. The strategies espoused by the integrated organisational employee engagement model developed in this study, can be used by organisations to increase organisational competitiveness by improving their employees’ level of engagement.

- Description: The research undertaken in this study was to identify the strategy needed to be adopted by the East Cape Motor Industry Cluster (ECMIC) in order to develop the competencies of its Team Leaders. v Hamel and Prahalad (1994: 28) are of the opinion that the focus of a company must move from current market share, to the share of tomorrow’s opportunities that the company can reasonably expect to gain. The company must therefore consider what it can achieve with its existing set of competencies, and what new competencies need to be acquired in order to prosper in the future. The development of competencies is thus deemed to be critical to the South African economy as the various local automotive manufacturers enter the export field. The ECMIC has traditionally been considered the heart of the automotive industry in South Africa with three of the major manufacturers located in the Nelson Mandela and Buffalo City Metropoles. In order to support these manufacturers, a vast number of component manufacturers and service providers have been established to support the automotive manufacturers both in the ECMIC and in other areas of the country. Since the establishment of a democratic South Africa and the removal of sanctions, the automotive industry has started to establish itself globally. This study will undertake a literature study of the application of competencies in the workplace, teams and team leaders and how competencies are applied in the ECMIC. The results of an empirical study into core competencies in the ECMIC will be used to elucidate a set of competencies which will be used to develop a strategy utilising the competency approach in team leaders in the ECMIC.

- Description: This study is about examining some changes to conventions and culture in selected Xhosa drama plays. Conventions are general agreements on social behaviour. They are the customary methods of presenting the elements of the text. There are no strict rules followed in the writing of plays, but there are conventions which vary from one playwright to another and from time to time. Conventions are the devices and the features of a literary work by which its kind can be recognized. Change creates anxiety, uncertainty and stress. Adaptation of culture to some changes plays a role as time passes by. To adapt to change is to be able to manage change. Managing change demands three levels of human response namely: the individual, the group and the cultural or social context. No matter how many changes are brought, different cultures should survive the changes for the nation to remain with its nationality. Industrialisation, urbanisation, religion, politics and economy are the agents of change. Also the social environment, human intelligence and culture play to a greater extent a role in the evolution process. Among other things, this study portrays that the changing times are reflected in Xhosa plays. This is the reflection of how people live, behave or do things, and think as time comes and passes. Pattern of development is traced through time, with the history being involved in the development. Change and development are unavoidable products of human thought. Development is traced from the primitive to the modern way of doing things. A modern or developed society is viewed as being capable of handling a wide variety of internal as well as external pressures. Every time a society manages a new pressure, its modernity improves. Thus, the word ‘modern’ has no time frame, as long as there is a new development, this term ‘modern’ features in. Though the study employs Evolutionary, Structuralist, Stylistic, Formalism and Marxist approaches, the branch of the Semiotic approach, Pragmatism, plays the major role in that the meaning of the texts is one of the semiotic categories. Again Semiotics deals with the writing and the interpretation of the text. Thus communication, adaptation and relating are fundamental to human existence and survival. It is easy to notice that there are old conventions that are continuing in the writings of the new generations of playwrights. This study compares and contrasts the similar conventions of dramatic texts, especially those that have the same theme and meaning. This study shows how the existing dramatic conventions are affected by time, history, economy, education, technology and some other changes. Though the dramatic conventions are said to be continuing, they also adapt to the changing time. There are conventional and cultural aspects that seem to be continuing, but it is a ‘changing continuity’. The developments or changes discussed in this study are in Xhosa drama conventions, those of culture of amaXhosa, dramatic construction of the Xhosa plays and in the interpretation of the plays.

An investigation of the binding capacities of recombinant domain mutants of the human Polymeric Immunoglobulin Receptor (pIgR)

- Description: The membrane bound glycoprotein, polymeric immunoglobulin receptor (pIgR) is the primary transport molecule of the polymeric immunoglobulins, dimeric IgA and pentameric IgM, across epithelial cells. This process, known as transcytosis, is essential in order to establish immunity at mucosal surfaces. Typically, pIgR binds to the polymeric immunoglobulin at the basolateral surface of the epithelial cell, via five homologous immunoglobulin-like domains of the ectodomain. Binding is covalent to IgA and non-covalent to IgM; the IgM binding varying among species. The pIgR-bound complex is released at the apical surface of the cell after cleavage of pIgR at Arg585, thereafter referred to as secretory component (SC). SC confers protective and immunologic functions to the polymeric immunoglobulin. Free SC, i.e. not complexed with polymeric immunoglobulins, is also known to be released into mucosal secretions; and binds to pathogenic bacteria and bacterial products. It is known that domain I of the ectodomain is the primary domain in the interaction with polymeric immunoglobulins, while domain V is involved in a covalent linkage with IgA. However, little is known of domains II-IV and their role in immunoglobulin binding, particularly to IgM. This study aimed to characterize the binding of recombinant human pIgR domain mutants to polymeric IgM using immunological, biophysical and cell based techniques; thereby allowing greater insight into the contribution of each of the five domains. The unique domain structure allowed for selective amplification of single and multiple domain mutants from cloned human PIGR ectodomain cDNA. Mutants were cloned and expressed in Esherichia coli BL21 (DE3) as inclusion bodies. Recombinant mutant proteins were refolded in vitro by equilibrium gradient dialysis and purified to homogeneity. Equilibrium binding data show significant contributions to specific binding as a factor of domain presence. Binding kinetics determined by biophysical surface plasmon resonance measurements show the interplay between association and dissociation rates as defined by individual domains. In vitro competitive binding studies using the human intestinal carcinoma, HT29, known to constitutively express pIgR, show that the constructed recombinant domain mutants outcompete native pIgR. The level of competition is shown to be dependant on the domains downstream of domain I. The data also confirm the biological activity of the first in vitro refolded recombinant human SC.

- Description: In this work, the growth and characterisation of the chalcopyrite semiconductor CuGaS2 is presented. The purpose of this study is to gain a better understanding of the defect chemistry of this class of materials through a systematic study relating the structural and optical properties to the composition of thin films grown by metalorganic vapour phase epitaxy. Details associated with the optimisation of the growth process are presented in a format relating the changes in the composition and morphology to variations in the growth process. The structural properties of thin films grown on GaAs(001) substrates are described. A dominance of polycrystalline growth is found to occur for Cu-rich material, whereas near-stoichiometric to Ga-rich material is typified by epitaxial growth. Secondary phases are identified by X-ray diffractometry and Raman spectroscopy for severely non-stoichiometric material. In some cases, the formation of the cubic zincblende and CuPt polytype of CuGaS2 are identified by transmission electron microscopy. It will be shown that changes in the Cu/Ga ratio of the solid strongly influence the photoluminescence response of the layers. Weak excitonic luminescence is observed for both slightly Ga-rich and Cu-rich material. Near stoichiometric layers exhibit luminescence centered at ~2.4 eV. Cu-rich layers are dominated by a line occurring at ~2.1 eV, whereas a different line at ~2.25 eV dominates for Ga-rich layers. A clear picture emerges of the radiative mechanisms dominating for Cu-rich and Ga-rich layers.

- Description: Type II diabetes is becoming a growing problem in developed countries worldwide. The median age for diagnosis was around sixty, but recent surveys have shown that the entire age distribution curve shifting left. The incidence of type II diabetes is thought to be parallel with the growing rate of obesity associated with an unhealthy western diet. Type II diabetes is an expensive disease to manage, it is for this reason that cheaper medication needs to be investigated in the form of traditional plants, such as Sutherlandia frutescens. Prescription medication, such as tricyclic antidepressants, may also increase body weight thereby playing a role in obesity. The cause of weight gain in such cases may go unrecognized or lead to cessation of the medication with or without the practitioner’s knowledge or approval. It is therefore necessary to investigate the causative agents responsible for the excessive weight gain. Drinking water containing extracts of S. frutescens or metformin was administered to two groups of eleven insulin resistant male Wistar rats. The insulin resistant control group received water without any medication. Rats were sacrificed after 8 weeks allowing for fasting blood glucose, insulin and tissue glycogen content determination. Glucose uptake was also determined using [3H] deoxyglucose. The effect of the medication and the diet on muscle post receptor insulin signaling proteins was determined through Western blots. Liver proteomics was also performed using 2-D electrophoresis. In a separate experiment 26 male Wistar rats were exposed to strepotozotocin toxin, 7 of these rats received intravenous insulin treatment, 7 rats received S. frutescens extract and 7 rats received a combination of both medications, the remaining 5 received no treatment and served as the control. Rats were sacrificed after 6 days allowing for fasting blood glucose, insulin and tissue glycogen content determination. Two groups of 14 male Wistar rats received amitriptyline or trimipramine (common tricyclic antidepressants) in their drinking water, the control group (30 rats) received water without any medication. The rats’ weight and food consumption was monitored throughout the trial and their oxygen consumption was also determined. Rats were sacrificed after 6 weeks or 14 weeks of medicinal compliance allowing for fasting blood glucose, insulin and tissue glycogen content determination. Glucose uptake was also determined using [3H] deoxyglucose. S. frutescens treatment normalized circulating serum insulin levels and significantly increased the rate of glucose clearance. Certain post receptor insulin signaling proteins were also significantly increased relative to the insulin resistant control group. 2-D electrophoresis identified the normalization of protein levels associated with the urea cycle. S. frutescens was also able to, independently; maintain normoglycaemic levels in the strepotozotocin treated group. The tricyclic antidepressants significantly increased blood glucose levels while significantly reducing tissue glycogen levels for both sacrifice periods. Serum insulin remained unchanged while a significant increase in insulin degradation and insulin degrading enzyme levels were found for both antidepressants. S. frutescens shows promise as a low cost antidiabetic medication for future use. Although the antidepressants did not promote weight gain, the increase in blood glucose levels may be cause for concern in patients with a pre-disposition toward developing diabetes.

- Description: A multi-input multi-output system to implement on-line process monitoring and intelligent control of complex curvature friction stir welding was proposed. An extra rotation axis was added to the existing three translation axes to perform friction stir welding of complex curvature other than straight welding line. A clamping system was designed for locating and holding the workpieces to bear the large force involved in the process between the welding tool and workpieces. Process parameters (feed rate, spindle speed, tilt angle and plunge depth), and process conditions (parent material and curvature), were used as factors for the orthogonal array experiments to collect sensor data of force, torque and tool temperature using multiple sensors and telemetry system. Using statistic analysis of the experimental data, sensitive signal features were selected to train the feed-forward neural networks, which were used for mapping the relationships between process parameters, process conditions and sensor data. A fuzzy controller with initial input/output membership functions and fuzzy rules generated on-line from the trained neural network was applied to perceive process condition changes and make adjustment of process parameters to maintain tool/workpiece contact and energy input. Input/output scaling factors of the fuzzy controller were tuned on-line to improve output response to the amount and trend of control variable deviation from the reference value. Simulation results showed that the presented neuro-fuzzy control scheme has adaptability to process conditions such as parent material and curvature changes, and that the control variables were well regulated.

- Description: A multi-input multi-output system to implement on-line process monitoring and intelligent control of complex curvature friction stir welding was proposed. An extra rotation axis was added to the existing three translation axes to perform friction stir welding of complex curvature other than straight welding line. A clamping system was designed for locating and holding the workpieces to bear the large force involved in the process between the welding tool and workpieces. Process parameters (feed rate, spindle speed, tilt angle and plunge depth), and process conditions (parent material and curvature), were used as factors for the orthogonal array experiments to collect sensor data of force, torque and tool temperature using multiple sensors and telemetry system. Using statistic analysis of the experimental data, sensitive signal features were selected to train the feed-forward neural networks, which were used for mapping the relationships between process parameters, process conditions and sensor data. A fuzzy controller with initial input/output membership functions and fuzzy rules generated on-line from the trained neural network was applied to perceive process condition changes and make adjustment of process parameters to maintain tool/workpiece contact and energy input. Input/output scaling factors of the fuzzy controller were tuned on-line to improve output response to the amount and trend of control variable deviation from the reference value. Simulation results showed that the presented neuro-fuzzy control scheme has adaptability to process conditions such as parent material and curvature changes, and that the control variables were well regulated. The presented neuro-fuzzy control scheme can be also expected to be applied in other multi-input multi-output machining processes.

- Description: In terms of the Constitution every person has the right to freedom and security of the person. This includes the right to be free from all forms of violence from either public or private sources. The state is charged with the duty to protect the individual from such harm. While the Constitution refers to the protection of victims of crime in broad and general terms without indicating how these rights should be protected, it makes meticulous and detailed provision for the rights of arrested, detained and accused persons. This leads to the popular belief that the Constitution protects the criminal and not the victim, engendering public dissatisfaction with the status quo, which is amplified by the fact that South Africa’s current legal dispensation for victims of crime does not embody the requirements of ubuntu and African customary law, which the Constitution declares to be binding on South African courts. This study analyses the means that exist in South African law for the victim of crime to obtain redress for criminal acts and proposes effective avenues through which victims can obtain redress, should the existing machinery prove to be inadequate. The term restitution is used to indicate recompense obtained from the perpetrator, while the term compensation refers to recompense obtained from the state. A comparative study is conducted to ascertain how the legal position of victims of crime in South Africa compares with that of victims of crime in Great Britain, India and New Zealand, respectively. South Africa does not have a state-funded victim compensation scheme such as those which exist in most developed countries. The respective proposals of the South African Law Commission for a victim compensation scheme and revised legislation to deal with offender/victim restitution are considered critically, inter alia, in the light of the findings of the comparative study. Proposals are made regarding changes to the South African legal system to bring it in line with international developments regarding restitution and compensation to victims of crime, attention being given to the meaning, significance and implementation of the doctrine of restorative justice when dealing with the aftermath of criminal injury. In addition to a complete revision of South African legislation dealing with offender/victim restitution, this study recommends the consolidation of the Road Accident Fund and the Compensation Fund operating in terms of the Compensation for Occupational Injuries and Diseases Act. These two bodies should be amalgamated to create a unified Compensation Scheme to compensate victims of crime, as well as victims of traffic and industrial injuries. General qualifying criteria for claimants would be drafted, with specific criteria applying in cases of traffic, industrial and crime related injuries, respectively.

- Description: Corporate scandals such as Enron, WorldCom and Parmalat, have focused recent governance efforts in the domain of financial reporting due to fraudulent and/or erroneous accounting practices. In addition, the ineffectiveness of the current system of controls has been highlighted, including that some directors have been weak and ineffective monitors of managers. This board of director ‘weakness’ has called for additional mechanisms for monitoring and controlling of management, focusing on financial reporting. This problem intensifies in that today companies function in real-time, and decisions are based on available realtime financial information. However, the assurances provided by traditional auditing take place months after the transactions have occurred and therefore, a trust problem arises because information is not verified in real-time. Consequently, the errors and fraud concealed within the financial information is not discovered until months later. To address this trust problem a conceptual causal model is proposed in this study based on the principles of systems theory. The emergent property of the causal model is increased trust and control. This study establishes that mutual assurances assist in building trust and that information security assists in safeguarding trust. Subsequently, in order to have a positive relationship between the company directors and various stakeholders, uncertainty needs to be contained, and the level of trust needs to surpass the perceived risks. The study concludes that assurances need to be provided in real-time to restore stakeholder confidence and trust in the domain of financial reporting. In order to provide assurances in real-time, continuous auditing is required to verify the integrity of financial information when it becomes available, and not months later. A continuous auditing process has its foundations grounded in information technology and attends to the challenges in real-time by addressing the standardisation of data to enable effective analysis, the validation of the accuracy of the data and the reliability of the system.

- Description: The South African wine industry is polarised into the quantity-producing majority and the quality-conscious minority [Hughes, 2003]. The qualityproducing sector of the South African wine industry is dominated by family businesses. Research shows that there are approximately ninety familyowned wineries in South Africa. By international standards, South Africa is viewed as a quantity, not quality producing wine country, which will make it difficult to survive in an industry where quality is paramount for recognition. The ‘trailblazers’ of the international wine industry are family owned wineries [Robinson, 2000]. Twenty five percent of the 2003 five star South African wines were made by individuals or family wineries [Hughes, 2003], emphasising the growing importance of family wineries in the production of quality wines. It is important now, more than ever, with the industry opening up internationally, that survival of the family-owned wineries and their production of icon wines are promoted so that they can become flagship producers of the industry. The achievement of international status as a quality producing country, as well as building an industry based on the longevity of wine producing families, as well as a nation of wine lovers in South Africa should result.

- Description: The primary objective of this study is to generate pathways to understanding Human Resources Development (HRD) by developing a tool which enables and enhances a shared and common understanding of HRD in South Africa (SA). To achieve this objective, this research explores the nature and importance of HRD and articulates and aggregates these thoughts and practices into a tool which facilitates an understanding of HRD with the overarching aim of improving HRD thoughts and practices in South Africa. While there is substantial international and local literature on HRD, the existing body of research on the nature and importance of HRD in South Africa is skeletal. National HRD concepts and practices are fragmented, and are as diverse as the number of stakeholders and partners that it serves. In addition, theory-building in HRD is disconnected and removed from practice. In order to address this problem, a qualitative, interpretive, theory-building social constructionist research strategy was embarked upon. The research strategy was executed in an iterative, cyclical manner, using theoretical sampling and content analysis rigorously executed within a coding paradigm informed by open, axial and selective coding techniques with local and international literature and informal reviews as the units of analysis. Qualitative and quantitative findings of the South African Qualifications Authority ground-breaking, world-first longitudinal study was analyzed and used to find relevance and corroborate the international literature available on HRD. Informal reviews were conducted with 7 human resources (HR) practitioners and 54 internationally-based HR colleagues of the researcher in order to ensure as appropriate a degree of integration between theory and practice as was possible. This process culminated in the most significant contribution of this research, which is a tool consisting of six pathways, that facilitates an understanding of the nature and importance of HRD in South Africa. The development of the tool enabled the articulation and aggregation of a thorough and coherent description, explanation and representation of HRD. The research highlights the need for HRD scholars and practitioners to channel their energies and effort on all the catalytic aspects of organizational life, namely uniqueness, social complexity, knowledge, and path dependency, by acquiring critical insight into the profound value of HRD which will allow the realization and sustainability of competitive advantage in a rich and dynamic global economy.

White women writing white : a study of identity and representation in (post-)apartheid literatures of South Africa

- Description: This thesis examines aspects of identity and representation using contemporary theories and definitions emerging out of a growing body of work known as whiteness studies. The condition of whiteness as it continues to inform identity politics in post-apartheid South Africa is explored in an analysis of selected texts written by white women, to demonstrate the ways in which whiteness continues to suggest normativity. In reading a representative selection of literatures produced in contemporary South Africa by white women writers, this study aims to illustrate the ambivalence apparent in the interstitial manifestations of emergent reconciliatory gestures that are at odds with residual traces of superiority. A sampling of disparate texts is examined to explore the representations of race and belonging in post-apartheid South Africa in the light of contemporary theories of whiteness which posit it as a powerful and invisible identification. The analysis attempts to plot a continuum from writers who are least, through to those who are most, aware of whiteness as a cultural construct and of their own positionality in relation to the discursive dynamics that inform South African racial politics. A contextualising overview of the terrain of whiteness studies is provided in Chapter One, marking the ideological and theoretical affiliations of this project, and foregrounding the construction of whiteness as an imagined identity in contemporary cultural criticism. It also provides a justification for the selection of the textual material under scrutiny. Chapter Two explores a genre that has been identified as a growing trend in South African fiction: the production of pulp fiction written by white middle-class women. Two such texts are the focus of this chapter, namely, Pamela Jooste’s People like Ourselves (2004) and Susan Mann’s One Tongue Singing (2005), and the complicities and clichés that are characteristic of popular literature are examined. Antjie Krog’s A Change of Tongue (2003) is the focus of Chapter Three. It is examined as a book offering the writer’s personal response to the difficulties of transformation within the first decade of South African democracy. Krog confronts her own defensiveness, her sense of normalcy, and her sense of alienation in relation to multiple encounters with different people. Chapter Four focuses on the journalism of Marianne Thamm. Her role as columnist for the popular women’s magazine, Fairlady is explored, particularly in relation to the inclusion of a contending voice writing against the general tenets of Fairlady. Thamm’s critique of the mores governing bourgeois white womanhood is read in relation to her role as officially sanctioned Court Jester. Her Fairlady columns have been collected in Mental Floss (2002) but the analysis includes selected columns from 2003 to 2005. Echo Location: A Guide to Sea Point for Residents and Visitors (1998) by Karen Press is the focus of Chapter Five. Her work is read as examining a white South African crisis of belonging in relation to the implications of mapping the co-ordinates of whiteness in South Africa. Chapter Six offers a reading of four short stories, written by Nadine Gordimer and Marlene van Niekerk. These stories are juxtaposed to trace an anxious impasse in white responses to suburbia, the place of enactment of white bourgeois mores, which both writers interrogate.
