- Description: This treatise is a qualitative study that critically explores a current body of knowledge significant to the development of the female adolescent voice. The female adolescent voice is a field that is relatively under-researched in comparison to the male adolescent voice, although research in this regard has shown an increase in interest in the last two decades (Gackle 2011: 11). However, information related to the male adolescent voice still far outweighs the female adolescent voice. This study, through the use of six secondary objectives, identifies and highlights areas of the female adolescent voice development, where much of the current research lacks depth and insight. It therefore analyses and compares applicable literature in an attempt principally to contribute to a more structured and academic approach in this field. Insight into the auditory effects that occur during physiological mutation is further supported by investigating the functioning of the female voice registers and the respective influences of these on the different phases of vocal development of the female adolescent. The assistance and expertise of the conductor in this process, as well as in common areas such as voice classification, auditioning, voice placement, and repertoire selection are investigated to further consolidate and compare possible interventions for problems pertaining specifically to the female adolescent voice. The study concludes with a summary of the treatise and proposes suggestions for further study in this field.

A Foucauldian critique of neo-liberalsim

- Description: This study attempts to make a contribution to the critique of contemporary capitalism. This has been conceptualised through a Foucauldian critique of neo-liberalism, that is, Foucault’s concepts of power and governmentality have been used to criticise neo-liberalism. The study argues that neo-liberalism is a hegemonic and oppressive politico-economic social system. This has occurred in two ways; firstly, neo-liberalism came to dominate the global economy and, secondly, neo-liberalism has become the dominant politico-economic discourse. An attempt is made to expose the discourses and institutions that buttress the neo-liberal project by undertaking a Foucauldian critique. According to Foucault, knowledge shapes the social space through its ‘mechanisms’, discourses and institutions. In order to critique neo-liberalism, it is necessary to expose its power-knowledge base, which is what gives it legitimacy. By analysing and exposing neo-liberalism’s power-knowledge base, its oppression becomes clear through an observation of the material effects of neo-liberal ideology and policy. This study also evaluates to what extent Marxism is a viable alternative to neo-liberalism, in order to ascertain what Foucault adds to already existing critiques of capitalism, and neo-liberalism, in particular. It concludes by arguing that even though Marxism provides a useful framework in which to understand neo-liberal domination, its labour based social theory is somewhat outdated in our contemporary age of the information society. Therefore, it is Foucault’s concept of power-knowledge that is most pertinent in providing an effective critical theory of neo-liberalism in the age of the information society, as it focuses on the primacy of power-knowledge in matters of domination.

A perspective on the question of the absence or presence of religious beliefs relating to elements of modern artistic endeavour, with special reference to the life and work of Francis Bacon

- Description: Preface: An awareness of certain contradictory perceptions and assumptions regarding religious beliefs today and their relevance to art prompted a question which led to the research undertaken in this minithesis. The question was: how significant is the absence or presence of religious beliefs to the modern creative process? The writings of some theologians, sociologists, psychologists, and anthropologists seem to indicate that religious beliefs are fundamental to the functioning of society and the individuals who are part of it. Furthermore, even a cursory study of the history of art will demonstrate the strong bond between pre-nineteenth century image making and organised religion. Today, however, this relationship appears uncertain or even non-cxistant. This is a result of processes which began to gain strength in the nineteenth century: these include the industrial revolution, scientism and materialism. Peter Fuller, stated that among the most central questions affecting art is, "the severance of the arts from religious tradition and their existence within an increasingly secular culture." (Fuller, 1990, p. 189). This statement appears to bring the issues together very neatly. Firstly there is the assertion that religion has nourished and been a vital force behind art through the ages, and that, modern art has lost this source of vitality. Secondly, there is the contention tbat society, since the nineteenth century, has become increasingly secular, and that this has had (and is having) a radical effect on modern art. That art has been divorced from religion and that religion is disappearing, or will do so, is the logical conclusion, according to theorists who insist on institutional religion as the only true form. Some artists, for whom the absence or presence or loss of religious beliefs are important issues, may in this situation experience a creative crisis. In order to address these issues it was necessary to investigate whether religious beliefs are important to artistic endeavour and, if so, what the consequences of the absence of beliefs might be. For this reason, research into the nature of religion and the modem religious situation was initiated. The purpose of the extensive discussion on the nature of religion was to establish definitions of, or a view of, religion which could provide a sound basis for this investigation of the issues that have been outlined. In order to demonstrate whether religious beliefs are important to the creative process, Francis Bacon was chosen for discussion because he appeared to be a modern artist who had no religious beliefs and was thus an ideal example by which the consequences of this could be gauged.

A satrean account of the role of social narratives in the identity-formation and self-conception of the queer and intersex subject

- Description: Successful, fully-fledged identity-formation and positive self-conception are contingent on the availability and sufficiency of social narratives. Following a Sartrean account of the human subject, identity will be shown to depend on externally-derived features (termed facticity). Facticity contains both material and social components. This thesis will show the two to be inextricably interlinked, and in so doing endorse Judith Butler's view that the material comes to us already seeped in social meaning. The interactive relationship between the discursive and the material will be illustrated by examining the phenomenon of intersexuality, in which the prevailing narrative of a dichotomized two-sex system has, through surgical, hormonal, and psychological procedures, become written into the flesh of non-binary individuals. The absence of affirming, diverse, and pluralistic narratives surrounding intersexuality, coupled with the imposition of the two-sex script, has (negatively) affected the material experiences, and subsequent identity-formation, of intersex individuals. Given the reliance of identity on socially-constituted facticities, the pursuit of flourishing, dignity, and an authentic and cohesive sense of self requires inclusive and diverse social scripts. Drawing on Mirander Fricker, I will elucidate how lacunae in the hermeneutical resource have resulted in confusion, unhappiness, and a lack of proper self-conception for individuals belonging to subjugated groups. Conversely, the availability of positive, diverse, and inclusive narratives will be shown to allow for more self-aware, self-determined subjects. I will ground my advocacy of inclusive, diverse social narratives in an examination of the beneficial genesis and development of the identity politics present in LGBTQIA++ movements (such as "Out and Proud", recognition of queer identity, and the development of non-binary gender). Assuming that self-understanding, authenticity, and flourishing are ethical goods that are valued, inclusive and affirming narratives for subjugated groups will be shown to be a normative necessity.

- Description: The highly sulphated, methylated polysaccharide isolated from Pachymenia Carnosa, a red seaweed, was shown to contain D- galactose, 2-o (underscore) methyl-D- galactose, 6-o (underscore) -methyl- D- galactose and 4-o (underscore)-methylgalactose. The polysaccharide was desulphated with methanolic hydrogen chloride. Methylation of the desulphated polysaccharide revealed that it was composed entirely of (1→73) and (1→4) links in approximately equal amounts. Treatment of the polysaccharide with alkali showed that the majority of the ester sulphate groups were alkali-stable. Partial hydrolysis and acetolysis studies indicated that the polysaccharide was extremely complex, and contained alternate (1→3) and β (1→4) glycosidic linkages. There is evidence for the presence of D-galactose-6-sulphate.

- Description: This is a quantitative study. The primary research objective is to investigate the importance of hospital management’s involvement when implementing lean elements in healthcare. In reality, incidents and quality problems are prime reasons why healthcare leaders are calling for redesign in healthcare delivery and systems. This paper presents a proposal for developing a lean culture in healthcare facilities equipped with managers who will be able to drive the implementation of lean elements from the top down, making use of multidisciplinary teams, including physicians, to deliver value-added services. This study ultimately endeavors to indicate the importance of management, multidisciplinary teams and physician involvement in implementing lean principles in healthcare successfully. “If we keep doing what we’re doing, we’re going to keep getting what we’re getting.” – Stephen Covey. The reasons why lean management is a particularly important strategy in healthcare currently, includes the following: •The need to reduce waste in healthcare cost; •The need to improve quality and on-time processes; •Fast-paced technological changes; •Ever-increasing patient expectations; and •The need to standardise processes and systems to get the high-quality results anticipated (Chalice, 2010).

It is so unfortunate that this computing technique has flaws that thrilled and edgy end users in implementing it effectively. These flaws include factors like lack of integrity, confidentiality and privacy to information. A secure cloud is impossible unless the computer-generated environment is appropriately secured. In any form of technology it is always advisable that security challenges must be prior identified and fixed before the implementation of that particular technology. Primarily, this study will focus on finding security issues in cloud computing with the objective of finding concerns like credential theft and session management in the ―Cloud‖. Main arguments like HTTP banner disclosure, Bash ―ShellShock‖ Injection and password issues were discovered during the stages of study implementation. These challenges may provide information that will permit hackers in manipulating and exploiting cloud environment. Identifying credential theft and session management in cloud-based file sharing technologies a mixed method approach was implemented throughout the course of the study due to the nature of study and unity of analysis. Penetration tests were performed as security testing technique. Prevention and guideline of security threats leads to a friendly and authentic world of technology.

- Description: This thesis describes an analysis of the F1 layer data obtained from the Grahamstown (33.32°S, 26.500 E), South Africa ionospheric station and the use of this data in improving a Neural Network (NN) based model of the F1 layer of the ionosphere. An application for real-time ray tracing through the South African ionosphere was identified, and for this application real-time evaluation of the electron density profile is essential. Raw real-time virtual height data are provided by a Lowell Digisonde (DPS), which employs the automatic scaling software, ARTIST whose output includes the virtual-toreal height data conversion. Experience has shown that there are times when the ray tracing performance is degraded because of difficulties surrounding the real-time characterization of the F1 region by ARTIST. Therefore available DPS data from the archives of the Grahamstown station were re-scaled manually in order to establish the extent of the problem and the times and conditions under which most inaccuracies occur. The re-scaled data were used to update the F1 contribution of an existing NN based ionospheric model, the LAM model, which predicts the values of the parameters required to produce an electron density profile. This thesis describes the development of three separate NNs required to predict the ionospheric characteristics and coefficients that are required to describe the F1 layer profile. Inputs to the NNs include day number, hour and measures of solar and magnetic activity. Outputs include the value of the critical frequency of the F1 layer, foF1, the real height of reflection at the peak, hmFl, as well as information on the state of the F1 layer. All data from the Grahamstown station from 1973 to 2003 was used to train these NNs. Tests show that the predictive ability of the LAM model has been improved by incorporating the re-scaled data.

- Description: Though it can be argued that the new democratic government has made tremendous strides in its first decades of democracy, continuing poverty and inequality tends to undermine the gains. Faced by this development dilemma, the government has adopted various development endeavours in an attempt to address issues of social and economic development. The topic of Local Economic Development has received considerable attention from both government and scholars in recent years. At the heart of the concept of LED are enshrined the goals of creating employment and promoting the economic growth and development of a locality or local area. It is in this context that the main objective of the study was to investigate the implementation of Local Economic Development as a cross-cutting dimension in the Integrated Development Plan of the Inkwanca Municipality of in the Eastern Cape Province. The construction of a bridge in the town of Sterkstroom was used as a case study to assess the ability of the municipality to plan and implement a LED project in a coordinated and integrated manner. The study used the combination of both methods of data collection, namely the qualitative and quantitative methods. The tool used to collect data was an interview schedule which consisted of open and closed ended questions. Findings by this study revealed that LED planning and implementation within the municipality does not receive the priority it so deserves and therefore it can not be regarded as the panacea for the development challenges confronted by the community in the municipality. Since LED has failed to create sustainable jobs and grow the local economy, questions can be raised about the efficiency of the municipality in its implementation of LED as a cross–cutting dimension. There appears to have been little cooperation with the LED Unit on the implementation of the Sokoyi Bridge construction project. Neither was there a concerted effort on the part of the municipality to use the project to build skills among the workers that they could use in future initiatives. The study revealed that the line function departments within the municipality could not plan their activities and programmes in a coordinated and integrated manner. Planning is characterised by ‘silo-functioning’. Furthermore, intergovernmental coordination amongst the various spheres of government has been and remains a challenge. Intergovernmental coordination and collaboration needed to be strengthened. The Integrated Development Plan of the municipality which is supposed to be a strategic coordination and integration tool has failed to achieve its objective and as such planning happens in an ad hoc and fragmented fashion. A plan-led system is needed to bring focus and allow long term public interest to guide the development of places. The National Development Plan state that “it will take time to create this capability, drawing on fuller understanding of the limitations of current arrangements and incorporating the lessons of good international practise.” (NDP, 2011: 263). Having a policy in place does not guarantee that there will be developmental or pro-poor outcomes. This study indicated that there are real capacity constraints in local government to plan in an integrated and coordinated manner. The Inkwanca Municipality did not use the developmental opportunities presented by the bridge construction project to its fullest extent. A lack of coordination limited the ability of the municipality to move beyond short-term job creation through a more integrated programme that could have had a broader positive impact on the residents of the Inkwanca municipality.

- Description: Though it can be argued that the new democratic government has made tremendous strides in its first decades of democracy, continuing poverty and inequality tends to undermine the gains. Faced by this development dilemma, the government has adopted various development endeavours in an attempt to address issues of social and economic development.

At the heart of the concept of LED are enshrined the goals of creating employment and promoting the economic growth and development of a locality or local area.

- Description: [Integrative Summary] This study is situated in the complex field of change management, and strategy execution. The study focuses on the corporate level restructuring of Ellerine Holdings Limited (EHL), subsequent to its acquisition by the micro lending financial institution African Bank Investments Limited (ABIL). The interest of the researcher was aroused by the uniqueness of the relationship. This was the first of its kind in a South African context, where a banker owned a furniture retailer. The restructuring was undertaken shortly after the acquisition. This research paper adopted a case study approach, in describing the restructuring initiative that took place in EHL, focusing on the period between January 2008 and the end of 2010/ 11 financial year on the 30th of September 2011. The case captures the significant phases of the restructuring including a background of (1) the protagonist, Toni Fourie (Chief Executive Officer), (2) EHL as the researched company, (3) the industry it operates in, and (4) the case content. Brief teaching notes have been provided to explain the teaching value of the case and to assist with its delivery in the classroom. Attention is drawn to a presentation by the protagonist in November 2011, named 'A CEO Insight' where he gave an overview and insights of the road travelled in restructuring Ellerine Holdings Limited, and more importantly highlights the following about the purpose and nature of the restructuring of the organisation. • A plan to change the way the industry works. • The creation of a profitable, stand-alone retail business through: o The sale of two companies, the closure of two companies and consolidating from thirteen to six brands. o Separating financial services from retail. o Moving the financial services component to African Bank, also a subsidiary of ABIL. o Redesigning the credit model. o Completion of twelve system changes. • Over R600million reduction in cost • A place where people want to work. The restructuring outlined above represents a major shake-up in many aspects of the corporation. The main challenge for Toni Fourie and his team was: how best could they restructure EHL to extract synergies between their two subsidiaries Ellerine Holdings Limited & African Bank to increase shareholders ' value at Group level. The case seeks to describe this in detail. The overarching strategy underpinning the restructuring of the researched corporation is premised on the price volume elasticity equation, by reducing the cost of credit, thereby driving pricing down within the brands, and facilitating more people having access to affordable credit. The case study of the restructuring is presented in Section 1. A review of relevant literature on strategy implementation is presented in Section 2, focusing on restructuring. Successful implementation of strategies only takes place with structures that are developed by organisations to support the achievement of their strategic objectives. Organisational architecture and design have a critical role to play in the execution of organisational strategies. Nadler and Tushman (1978) emphasise the importance of congruence in the organisational design, for the organization to not only deliver superior results but to sustain them over a period of time. Research by Okumus (2005) seems to tell us that the lack of credible framework to implement strategy, has contributed the high failure rate of strategy initiatives. Although this is a strategy implementation case, it also touches on aspects of leadership - mainly the architectural role - and the role, or influence of strategic leadership, in restructuring the corporation. The results of this research paper were achieved by following a specific research methodology. The aim of the research was to analyse the restructuring of the researched company at corporate level, having the following objectives in mind; • Understanding the strategy. • Analysing the design decisions in the light of the strategy chosen by the top management of Ellerine Holdings Limited. • Analysing what monitoring and control measures had been designed to facilitate the corporate restructuring. Data was collected through documentation of the corporation that was made available to the researcher on request, as well as those that are in the public domain, and an interview with the CEO of the researched company. The interview was conducted after analysing the documentation (Hakim, 2000). The Methodology is detailed in Section 3. The researcher hopes that the case study will contribute to learning about business leadership and strategic management. The case should develop an understanding of the complexities related to strategy execution at corporate level, particularly the restructuring aspect of it.

Browsing as a demographic bottleneck in a semi-arid savanna: the effect of size and age on compensatory responses of Vachellia karroo seedlings after simulated herbivory

- Description: Savannas are characterised by a continuous grass layer with scattered trees at varying densities. This vegetation structure is determined by several interacting factors, including fire, herbivory, resource competition and atmospheric CO2 concentration. The preservation of savanna biomes is important and a shift towards a woody biome threatens savanna globally. Bush encroachment which describes the shift towards domination of savannas by C3 woody plants, is especially acute in southern Africa. In semi-arid rangelands, encroachment progresses to dense thickets dominated by thorny and unpalatable bushes and trees. There is evidence that bush encroachment is driven by a reduction in fire and browsing events as well as their interaction. Despite browsing having strong effects on African savannas its isolated role in maintaining tree-grass coexistence has not received as much attention as the role of fire. Therefore the overall aim of this study was to examine the effects of browsing on seedlings of a commonly encroaching species, Vachellia karroo. Browsing was hypothesized to be a demographic release bottleneck for bush encroachment in a semiarid (MAP ~550mm) savanna in the Eastern Cape of South Africa, where fire has been historically rare. In a single study I explored the fate of V. karroo seedlings (less than a year old) following browsing in sub canopy and inter canopy microhabitats. Additionally, I explored how the fate of a seedling changed under high and low tree cover. Firstly, I investigated the type, intensity and frequency of herbivory, from both small and large herbivores, which seedlings were subjected to. Results revealed that browsing was severe and frequent with the majority of seedlings browsed more than twice over a 12 month period. Large browsers such as kudu and impala caused high seedling mortality (46%) while smaller browsers such as invertebrates were more effective at suppressing growth. Microhabitat had little impact on seedling survival, but significantly influenced plant compensatory growth. Reduced seedling growth following browsing was observed in the sub-canopy in comparison to seedling growth in full sunlight in the intercanopy, suggesting V.karroo may be shade intolerant. Secondly, the effect of tree cover on browsed seedlings was determined by quantifying browsing frequency and intensity at high and low tree cover. No differences in browsing intensity and frequency were observed between high and low tree cover. However, high tree cover due to bush encroachment limited seedling above ground growth. The aim of the second study was to investigate how V.karroo survival and growth were influenced by its age and size following simulated browsing. I explored this aim through field and greenhouse experiments. I was particularly interested in testing how plant sensitivity to varying defoliation intensities of repeated browsing varied with plant age (known ages of 6, 12, 16 and 30 weeks). There were large differences in mortality between the different age groups. Furthermore, age interacted with repeated browsing and negatively influenced seedling survival and regrowth. Older seedlings (16 and 30 week old) had greater survival and higher browsing frequencies resulted in greater mortality and reduced growth. The threshold age after which seedlings become more tolerant to herbivory occurs at an age of 28 weeks. Seedlings less than six weeks old experiencing intense (100 % defoliation)browsing had a very low probability (33%) of survival following just a single defoliation. Interestingly, all 16 week old seedlings regrew most of their foliage following a moderate (50%) defoliation with some plants overcompensating for leaf loss. The field study revealed two distinct demographic stages based on age and size (seedlings< 9 mm and saplings >9 mm in stem basal diameter (SBD)). Browsing had a strong negative effect on seedlings, resulting in reduced investment in leaf biomass. These findings suggest plant size and age can be used as robust predictors of a plants vulnerability to browsing. An increase in tree cover requires successful transitions of seedlings to saplings (also known as release). The results of this study suggest that in semi-arid savannas, browsing can impact tree cover through imposing a release bottleneck for tree seedlings and to lesser extent saplings. By limiting tree growth plants are kept in a disturbance trap and will therefore be exposed to not only browsers but fire. These findings also have important implications for tree-grass coexistence dynamics, suggesting that specific size and browsing thresholds should be considered in savanna management.

- Description: South Africa is faced with enormous backlog of service delivery which is attributed to the apartheid government and performance challenges especially in areas like Eastern Cape. It was then identified that there was no uniform system to monitor and evaluate performance of government institutions and the impact of the services they render to the community. The government then adopted a monitoring and evaluation system called Government - Wide Monitoring and Evaluation System for all government departments and municipalities. This study analysed the implementation of this Government-Wide Monitoring and Evaluation System in Eastern Cape Municipalities with specific reference to Chris Hani District Municipality. It further assessed the effectiveness of this monitoring and evaluation system and whether its implementation has improved performance in municipalities, so as to identify the hampering limitations and the appropriate improvement strategies that can be recommended. In order to reach conclusions to the questions and objectives, the study was conducted using qualitative research methodology. Interviews were conducted as described in chapter 3. Chapter 4 presents the findings that were achieved from the interviews and the interpretation of these findings whilst chapter 5 presents conclusion and recommendations based on the findings.

- Description: Search and retrieval of multimedia content from open platforms such as the Internet and IPTV platforms has long been found to be hugely inefficient. It has been noted that a major cause of such inefficient results is the improper labeling or incomplete description of multimedia content by its creators. The lack of adequate description of video content by the proper annotation of video content with the relevant metadata leads to poor search and retrieval yields. The creation of such metadata itself is a major problem as there are various metadata description standards which users could employ. On the other hand there are tools such as FFprobe that can retrieve important features of video that can be used in searching and retrieval. The combination of such tools and metadata description standards could be the solution to the metadata problem. The Multimedia Content Description Interface (MPEG-7) is an example of a metadata description standard. It has been adopted by TISPAN for the description of IPTV multimedia content. The MPEG-7 standard is rather complex, seeing as it has over 1200 global Descriptors and Description Schemes which a user would have to know in order to implement such technology. This complexity is a nuisance when we consider the existence of multitudes of amateur video producers. These multimedia content creators have no idea how to use the MPEG-7 standard to annotate their creations with metadata. Consequently, overloading of the IPTV platform with content that has not been annotated in a standardized manner occurs, making search and retrieval of the multimedia content (videos, in this instance) inefficient. Therefore, it was imperative to try and determine whether the use of the MPEG-7 standard could be made much easier by creating a tool that is MPEG-7 enabled which will allow for the annotation of video content by any user without concerning themselves about how to use the MPEG-7 standard. In attempting to develop a tool for metadata generation, it was incumbent for us to understand the issues associated with metadata generation for users wishing to create IPTV services. An extensive literature review on IPTV standardization was carried out to determine the issues associated with metadata generation for IPTV and their proposed solutions. An experimental research approach was taken in an attempt to figure out if our proposed solution to the lack of technical expertise by users about the MPEG-7 standard could be the final solution to the metadata generation problem. We developed a Multimedia Content Description and Management System (MCDMS) prototype which enabled us to describe video content by annotating it with 16 different metadata elements and storing the descriptions in XML MPEG-7 format. Incremental development and re-use oriented development were used during the development phase of this research. The MCDMS underwent functional testing; smoke testing of the individual system components and Big Bang integration testing for the combined components. Our results indicate that the more metadata is appended to a video as description the better it is to search for and retrieve. The MCDMS hides the complexity of MPEG-7 metadata creation from the users. With the effortless creation of MPEG-7 based metadata, it becomes easier to annotate videos. Consequently, search and retrieval of video content becomes more efficient. It is important to note that the description of multimedia content remains a complex feat. Even with the metadata elements laid out for users, there still exist other issues that affect metadata creation such as polysemy and the semantic gap. However, the provision of a tool that does the MPEG-7 standardizing behind the scenes for users when they upload a video makes the description of multimedia content in a standardized manner a much easier feat to achieve.

Incremental development and re-use oriented development were used during the development phase of this research. The MCDMS underwent functional testing; smoke testing of the individual system components and Big Bang integration testing for the combined components. Our results indicate that the more metadata is appended to a video as description the better it is to search for and retrieve. The MCDMS hides the complexity of MPEG-7 metadata creation from the users. With the effortless creation of MPEG-7 based metadata, it becomes easier to annotate videos. Consequently, search and retrieval of video content becomes more efficient. It is important to note that the description of multimedia content remains a complex feat. Even with the metadata elements laid out for users, there still exist other issues that affect metadata creation such as polysemy and the semantic gap. However, the provision of a tool that does the MPEG-7 standardizing behind the scenes for users when they upload a video makes the description of multimedia content in a standardized manner a much easier feat to achieve.

Ethnic nationalism and democratisation in South Africa : political implications for the rainbow nation

- Description: Ethnic identities in South Africa have had a particularly contrived history, set within the constraints and motivations of population classification by race. A more democratic political environment emerged with the dismantling of apartheid, bringing with it a multitude of issues including the design and character of the country’s political institutions and framework. This thesis will address two principal questions. The first and primary one investigates what lies behind the initiation and development of ethnic bonds. The second concerns the political implications and management of ethnic expressions in a democratic South Africa. An analysis of Zulu ethnic nationalism will be undertaken, because it constituted the most prominent case of assertive communal interests during democratic transitional negotiations. This thesis argues that circumstantial and instrumental factors (based on conditions, and the actions of individuals and organizations respectively), have been predominately responsible for the initiation and formation of ethnic bonds, especially amongst those who identify with a Zulu identity. The “conditions” describe the increasingly segregationist direction in which successive South African government authorities were moving, especially after the 1948 election victory of the National Party and the subsequent introduction of apartheid. Secondly, the “actions” denote the motivations of both Zulu actors and governments in generating and elaborating an ethnic discourse where their desired interests could be more effectively supported and assured. It will also be argued that because of the instrumental and selective use of ethnicity, as well as the narrow interests being served by its popular and community-centred expressions, a developing South African democratic culture should seek to protect ethnic diversity rather than promote ethnic interests. To do so would be to deny the perpetuation of ethnic cleavages and the violence and instability perpetrated in its name in recent years. The “protection” of cultural diversity is consistent with a constitution that seeks non-discrimination among all South African identities. Finally, it is believed that an emphasis on the individual as individual, as well as member of a cultural group, will break from subordinating the individual to an ascribed racial and ethnic identity as in the past, and assist in reconstituting the state as equally reflective of all South Africans.

- Description: The goal of this research study was to explore and describe the experiences of parents whose children have completed the diversion programme in order to make recommendations to probation officers, social workers and people who facilitate the diversion programmes. The study focused on the Youth Empowerment Scheme programme (YES Programme) because it is the diversion programme mostly used in the Eastern Cape. The aim of the programme is to divert young people in trouble with the law away from the criminal justice system and to rehabilitate the young offenders by providing them with essential life skills that can address the offenders’ real problems. In the study the researcher made use of a qualitative research approach in an attempt to explore the experiences of parents whose children have completed the YES programme. The permission of the gatekeeper was sought before the study commenced. The researcher used purposive sampling to recruit participants. Data was collected by means of semi-structured interviews. In analysing the data, the researcher used the steps for qualitative data analysis as stated in Creswell (2003:192). Three main themes along with sub-themes and categories were identified during the process of data analysis. The main findings that emanated from this study were: the seemingly upcoming culture of lack of respect for authority on the part of the youth of today. Another major finding of this study is that the traditional function of families, notably, socialisation of young people within the family structure is on the wane. The recommendations that emanated from this study are: that the YES programme needs to be adjusted to address the specific needs of children that are referred to the YES programme and those of their families and communities. Family life should be strengthened through community development programmes that seek to address family problems of any nature, namely, material, psycho-social, economic, to mention just a few. Community development programmes should address fragile families through community development approaches that are comprehensive and integrated.

- Description: The aim of this study was to explore the role of job satisfaction and organizational justice in determining employee motivation among nurses at Frontier Hospital, Queenstown. For this purpose data was collected from the nurses at Frontier Hospital in Queenstown, in the Eastern Cape. A sample of 75 nurses was drawn from the population. Results of the study indicated that the study variables are significantly and positively correlated with one another. Job satisfaction was found to be significantly and positively correlated with employee motivation. Organizational justice was also found to be significantly positively correlated with employee motivation. Moreover, a positive and significant relationship between job satisfaction and organizational justice was found. The findings of this study are helpful in the health industry in order to design human resources policies, which will reduce the turnover of nurses by increasing their motivation through increasing job satisfaction and organizational justice.

Externalism, self-knowledge and explanation

- Description: In recent years, much attention has been given to the question of whether content externalism is compatible with an account of self-knowledge maintaining that we have an epistemically privileged access to the content of our propositional mental states. Philosophers who maintain the two are incompatible (incompatibilists) have put forward two majors types of challenge, which I call - following Martin Davies - the Achievement and Consequence Problems, which aim to demonstrate that self-knowledge cannot be reconciled with externalism. These challenges have spawned a great deal of literature, and a diverse range of arguments and positions have emerged in response. In this dissertation, I intend to focus on examples of these different avenues of response, and show how none of them are adequate. In the first chapter, I lay the groundwork for the debate, setting up how externalism and self-knowledge are to be understood, and outlining both the incompatibilist challenges as well as the available responses to them. In the second chapter I examine these responses in more detail, concluding finally that the best available response is Tyler Burge's. Burge has two arguments that together establish his compatibilist position. First, he shows that even if externalism is true, our judgements about our occurrent thoughts are immunejrom error. This establishes that our judgements about our thoughts must be true. Second, he offers a transcendental argument for self-knowledge, arguing that our access to our mental states must be not only true, but non-accidentally true, in a way sufficient for genuine knowledge. This establishes that we possess the correct epistemic entitlement to our thoughts. In the third chapter, I argue Burge's arguments do not, in fact, give us good reason to suppose externalism and self-knowledge to be compatible. This, I argue, is because B urge relies upon a transcendental argument, which, in this context, cannot establish that we have self-knowledge if externalism is true. All it establishes, I argue, is that we do possess self-knowledge. And this is insufficient to establish that externalism and self-knowledge are compatible. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The process of globalisation has had a large impact on the world economy over the past three decades. Economic globalisation has manifested itself in the increasing integration of goods and services through international trade and the integration of financial markets. As a consequence the existence of co-movements in economic variables of different countries has become more evident. The extent to which globalisation causes a country’s economy to move together with the rest of the world concerns policy-makers. When such co-movement is significant, the influence of policy-makers on their respective domestic economies is significantly reduced. South Africa re-entered the international economy in the early 1990s when the forces of globalisation, especially for developing countries, seemed to gain momentum. Empirical research such as Kabundi and Loots (2005) found strong evidence of international co-movement between the world business cycle and the South African business cycle, particularly following South Africa’s integration into the global economy. This study examines the relationship and interdependence between South Africa and four of its major developed trading partners. More particularly, the study examines the question of whether business cycles are transmitted from Germany, Japan, US and UK to South Africa, and/or from South Africa to Germany, Japan, the US and UK. The study employs structural vector autoregressive (SVARs) models to analyse monthly data from 1980:01–2008:04 on industrial production, producer prices, short-term interest rates and real effective exchange rates. The results show that South Africa benefits from economic growth in both the UK and US. They also indicate significant price transmission from Germany and Japan to South Africa, with transmission in the opposite direction being statistically insignificant. The impulse response graphs show that a positive one standard deviation shock to both German and Japanese producer prices has a negative impact on South African output (industrial production) growth. Furthermore, South African monetary policy is relatively unresponsive to international monetary policy stances. The findings of this study indicate that South African policymakers need to take into consideration economic performance of the country’s major trading partners, with particular emphasis on the UK and US economies.
