- Description: The presence of human destitution, impoverishment and degradation in the midst of plenty has puzzled social thinkers for millennia. One of the oldest and grandest of theories: the theory of ideology attempts to provide an answer to the puzzle of domination in society. Michael Rosen, in his book On Voluntary Servitude (1996), argues that the solution provided by the theory of ideology is problematic. Furthermore, on the basis of his critique, Rosen argues that we should abandon the theory of ideology and consider alternatives to it. Even though many contemporary academics have turned away from the theory of ideology, because they view it as an imprisoning meta-theory, this study explores the possibility of there being a meta-theory that could help us to make sense of the world. Through an examination of Rosen's critique this thesis shows that Rosen is too quick in his dismissal of the theory of ideology because he fails to consider that a revised functionalist theory of ideology can be expanded to account for the mechanism(s) that ensure that, over time, the society in question acquires ideological consciousness to further its welfare. This thesis shows that Rosen is correct in his criticism of the theory of ideology's explanation of domination because the content, history and social effects of ideological consciousness cannot be fully explained in terms of their role in promoting or stabilising relations of domination. In light of Rosen's criticism the thesis shows that if one provides both an explanation of the psychological motivations of individuals and of the nature of the oppressive society in which they find themselves then what I call an integrated theory of ideology can be developed. In order to illustrate the importance of an integrated theory of ideology the study moves away from high-level theoretical abstraction to concrete social analyses, focusing on the work of Frantz Fanon and Steve Biko and their explanations of domination. The reason this study focuses on their work is because in their role as social scientists, Fanon and Biko provided a powerful critique of colonial, post-colonial and neo-colonial society. It will be argued that Fanon and Biko were able to provide a lasting critique of colonial reality because they offered their critique within the framework of such an integrated theory. Consequently, this study argues that, as Fanon and Biko's work illustrate, an integrated theory of ideology qua critical theory ought not to be abandoned because it is crucial for understanding and resisting forms of oppression that exist in the world today.

- Description: The community structure and predation impact of carnivorous macrozooplankton (>2 cm; chaetognaths, medusae, ctenophores and mysids), with particular emphasis on the chaetognaths Eukrohnia hamata and Sagitta gazellae, were investigated during three surveys conducted in late austral summer (April/May) of 2001, 2004 and 2005 in the Polar Frontal Zone in the vicinity of the Prince Edward Islands (46º45’S, 37º50’E), Southern Ocean. The 2001 survey formed part of the Marion Offshore Variability Ecosystem Study (MOVES II), while the 2004 and 2005 surveys formed part of the Dynamics of Eddy Impacts on Marion’s Ecosystem study (DEIMEC III and IV respectively). Macrozooplankton samples were collected using WP-2, RMT-8 and Bongo nets. Results of the hydrographic survey indicated that the region of investigation, the Polar Frontal Zone (PFZ), is an area of high mesoscale variability. During the 2004 survey the Antarctic Polar Front (APF) and the Subantarctic Front (SAF) merged to form an intense frontal feature with subsurface temperature and salinity ranging from 8.5-7.5ºC and 34.15-33.88, respectively. A cyclonic cold core eddy, believed to have been spawned from the APF, was observed during the 2005 survey. Macrozooplankton abundance and biomass ranged from 0 to 43.731 ind. m⁻³, and from 0 to 41.55 mg wwt m⁻³ respectively, during the three surveys. Among the carnivorous macrozooplankton, chaetognaths (Eukrohnia hamata and Sagitta gazellae) were most prominent, contributing up to 85% of the total biomass during all three surveys. Elevated biomass values were found near and within the frontal feature during the 2004 survey, and also along the eddy edge during the 2005 survey. However, hierarchical cluster analysis did not reveal the presence of distinct zooplankton groupings associated with the various water masses encountered during the surveys and this is probably due to the high mesoscale variability in oceanographic conditions that are characteristic of the PFZ. The total average predation impact of the selected carnivorous macrozooplankton during the 2001, 2004 and 2005 surveys accounted for 4.93 ± 6.76%, 0.55 ± 0.51% and 4.88 ± 4.45 of the mesozooplankton standing stock, respectively. S. gazellae had the highest consumption rate in all three surveys, consuming up to 800 g Dwt 1000m⁻³d⁻¹ during the study. Of the two chaetognaths, E. hamata dominated the chaetognath standing stock. The combined abundance and biomass values of E. hamata and S. gazellae ranged from 0 to 43.73 ind. m⁻³ and from 0 to 41.551 mg wwt m⁻³ respectively, during the three surveys. Inter-annual variability in the chaetognath densities was apparent. Highest abundances and biomasses tended to be associated with specific water masses, confirming the existence of a relationship between zooplankton community structure and hydrographic conditions. Generally, about 90% of the chaetognaths contained no food in their guts. S. gazellae consumed a wider variety of prey. Oil droplets occurred in the guts of ≈ 51% of E. hamata. Cannibalism was low in both species, but greater in S. gazellae than E. hamata. During the three surveys, the feeding rate values of E. hamata and S. gazellae went up to 0.48 and 2.099 prey d⁻¹ respectively. S. gazellae also had a greater predation impact on the mesozooplankton standing stock than E. hamata. The mean predation impact of the chaetognaths combined was 0.31 ± 0.291%, 0.52 ± 0.28% and 0.53 ± 0.56% of the mesozooplankton standing stock during the 2001, 2004 and 2005 surveys, respectively. During all three surveys, the majority of individuals (≈ 76%) of the chaetognaths were at stage I maturity, suggesting that during the time of study the chaetognaths were not reproducing. In both species a significant difference (log-linear analysis, p < 0.05) in maturities between the years investigated was observed. In general, there were no differences in lengths and maturities between the different water masses encountered during the surveys. The lengths of E. hamata and S. gazellae ranged from 5 to 24 mm and from 9.4 to 63.6 mm, respectively.

- Description: The ichthyofaunal community structure, population dynamics and movement patterns in the small temporarily open/closed (TOCE) Grant’s Valley estuary, situated along the Eastern Cape coastline, were investigated over the period May 2004 to April 2005. Community structure in the littoral zone was assessed, while growth of selected ichthyofaunal species was investigated using the MULTIFAN model. Population size was assessed using mark recapture models and movement within the estuary using the Hilborn (1990) model. Total ichthyofaunal densities and biomass within the littoral zone ranged between 0.31 to 21.45 fish m⁻² and 0.20 to 4.67 g wwt m⁻², with the highest values typically recorded during the summer. Results of the study indicated that the ichthyofaunal community structure within the estuary was closely linked to the mouth phase and the establishment of a link to the marine environment via overtopping events. In the absence of any link to the sea, the ichthyofaunal community was numerically dominated by estuarine resident species, mainly Gilchristella aestuaria and to a lesser extent, by the river goby, Glossogobius callidus which collectively comprised ca. 88% of all fish sampled. The establishment of the link to the marine environment contributed to an increased contribution of marine breeding species (e.g. Rhabdosargus holubi, Myxus capensis and Atherina breviceps) to the total ichthyofaunal abundances. In contrast, total ichthyofaunal biomass was almost always dominated by marine breeding species by virtue of their larger sizes. Results of hierarchical cluster analyses did not identify any spatial patterns in the ichthyofaunal community within the littoral zone. Results of MULTIFAN analysis indicated estuarine resident fish species bred over an extended period with peaks occurring in the summer months. Conversely, marine breeding fish were shown to recruit into the estuary following overtopping and breaching events. Results of the mark-recapture experiment indicated a population of ca. 12 000 (11 219 – 13 311) individuals greater than 50mm SL. Marine-breeding species (R. holubi, Monodactylus falciformis, and two mullet species) numerically dominated the ichthyofauna, possibly as a result of their effective use of overtopping events. The two mullet species, M. capensis and Liza richardsonii, and the Cape stumpnose, R. holubi moved extensively throughout the estuary, while the remaining species exhibited restricted movement patterns possibly due to the preference for refuge and foraging areas associated with reed beds. The observed movement patterns of individual fish species appeared to be associated with both foraging behaviour and habitat selection.

- Description: Grid computing technologies facilitate complex scientific collaborations between globally dispersed parties, which make use of heterogeneous technologies and computing systems. However, in recent years the commercial sector has developed a growing interest in Grid technologies. Prominent Grid researchers have predicted Grids will grow into the commercial mainstream, even though its origins were in scientific research. This is much the same way as the Internet started as a vehicle for research collaboration between universities and government institutions, and grew into a technology with large commercial applications. Grids facilitate complex trust relationships between globally dispersed business partners, research groups, and non-profit organizations. Almost any dispersed “virtual organization” willing to share computing resources can make use of Grid technologies. Grid computing facilitates the networking of shared services; the inter-connection of a potentially unlimited number of computing resources within a “Grid” is possible. Grid technologies leverage a range of open standards and technologies to provide interoperability between heterogeneous computing systems. Newer Grids build on key capabilities of Web-Service technologies to provide easy and dynamic publishing and discovery of Grid resources. Due to the inter-organisational nature of Grid systems, there is a need to provide adequate security to Grid users and to Grid resources. This research proposes a framework, using a specific brokered pattern, which addresses several common Grid security challenges, which include: Providing secure and consistent cross-site Authentication and Authorization; Single-sign on capabilities to Grid users; Abstract iii; Underlying platform and runtime security, and; Grid network communications and messaging security. These Grid security challenges can be viewed as comprising two (proposed) logical layers of a Grid. These layers are: a Common Grid Layer (higher level Grid interactions), and a Local Resource Layer (Lower level technology security concerns). This research is concerned with providing a generic and holistic security framework to secure both layers. This research makes extensive use of STRIDE - an acronym for Microsoft approach to addressing security threats - as part of a holistic Grid security framework. STRIDE and key Grid related standards, such as Open Grid Service Architecture (OGSA), Web-Service Resource Framework (WS-RF), and the Globus Toolkit are used to formulate the proposed framework.

- Description: This dissertation sets out to find a pragmatic solution for optimizing both resolution and rendering issues in the context of contemporary environmental design computer modelling. In this regard the following issues are addressed: Firstly, determining (with reference to a limited selection of existing 3DS Max software and plugins (i.e. VRay and Mental-Ray), which specific piece of software produces the best compromise as far as visual accuracy is concerned whilst still offering the designer the best scope for further design manipulation. Secondly, establishing design techniques which can increase the speed of model making as well as reduce rendering time without having an adverse effect on issues such as resolution and image quality. Lastly, ascertaining the least number of surfaces for a typical geometrical shape (e.g. chair, table, ornament etc.) without losing visual veracity by manipulation of the design itself. The research strongly supports the notion that VRay is the best overall software to be employed as a base before applying any design solutions. In this latter regard a number of solutions became evident as a means to both save memory and cut down on rendering time, including such factors as using spotlight rather than an omni light when rendering, because omni light calculations include the generation of needless shadows. The beneficial effect of employing ‘target direct’ light and reducing the area of light in order to decrease the calculation of shadow. Eliminating objects which do not need shadows from the lighting calculation and shutting off the reverberation and refraction factors before rendering. It was also confirmed that a black and white mipmap is better than a colour mipmap as far as saving on the system’s memory.

- Description: The Chinese inbound tourism market to SA has been acknowledged as an emerging market. However, South African tour operators experience difficulties in establishing and developing viable partner relationships with Chinese travel agents. Recognizing the size, importance and complexity of this market, the major purpose of this research is to explore and investigate the crucial process of developing Sino-South African partnership relationships in the tourism industry, to facilitate the establishment of business relationships with Chinese travel agents. This study is draws on applied marketing, management and cross-cultural theories on networking to explore the process of developing partnership relationships in the Chinese inbound tourism market to SA. The literature on networking, the development of networking relationships, and the effect of guanxi (connection), a key feature of Chinese business networking on partnership relations are reviewed. Given the limited research conducted on this topic and its cross-country nature, a quantitative research method was adopted for this study. Specifically, this study utilized e-mail survey techniques to explore the relationships between South African inbound tour operators and Chinese travel agents. This study identifies that the process of developing partnership relationships between Chinese travel agents and South African inbound tour operators is culturally embedded. They are giving rise to communication problems that affect partnership relationships. A new stage model of the development of partnership relationships between South African inbound tour operators and Chinese travel agents is therefore developed. In particular, the study identifies important factors in the process of developing business relationships. For example, mutual commitment, the pricing issue, word-of-mouth, and quality of services are all considered crucial in attaining long-term stable partnership relationships. Guanxi plays a significant, but not decisive role in the process of developing partnership relationships between Chinese travel agents and South African inbound tour operators. However, guanxi relationships can provide added value to the partnership relationships.

- Description: The Chinese inbound tourism market to SA has been acknowledged as an emerging market. However, South African tour operators experience difficulties in establishing and developing viable partner relationships with Chinese travel agents. Recognizing the size, importance and complexity of this market, the major purpose of this research is to explore and investigate the crucial process of developing Sino-South African partnership relationships in the tourism industry, to facilitate the establishment of business relationships with Chinese travel agents.

- Description: This thesis aims to provide a better understanding of the ways in which the Internet supports the consumer decision process of potential customers in an online car retail environment. The thesis is mainly focused on how this can be done in South Africa. A case study approach was adopted in investigating the case of McCarthy Call-a-Car. Interviews were carried out with McCarthy Call-a-Car employees and documents and the Call-a-Car website, were analysed. It was revealed that Call-a-Car focuses on using the Internet to support customers in the pre-purchase phase only. The purchase and post-purchase phases are carried out offline at its dealership network and Club McCarthy respectively. The findings showed that Call-a-Car views the Internet as a marketing tool that provides convenience to customers searching for product information in the pre-purchase phase. The interviews revealed that due to Call-a-Car's strategy, as well as practical problems of selling online, the customer will still have to visit a dealership to conclude a purchase and for post-purchase support. From this research it appears that there are three main issues arising out of Call-a-Car's usage of the Internet in the customer buying process: firstly, the research revealed that instead of cutting out the middle-man, the Internet has created new types of intermediaries called "cybermediaries" and that Call-a-Car is one such intermediary. Secondly, it was revealed that trust is crucial in the online environment and that Call-a-Car builds trust through branding. Thirdly, the Internet has not affected prices online, despite theoretical estimations that the Internet would induce lower prices. The main recommendations for future research are empirical studies to investigate if the cybermediary model is unique to the car industry and whether this business model could be applied to other look and feel industries such as real estate. Future studies could also investigate the mechanics of trust-building and brand-building in the online environment and finally, studies from the customer perspective considering what Internet tools the customer would like to see online to support them during their buying decision process.

- Description: The purpose of this study was to critically investigate challenges in the provision of low-income housing in the Nelson Mandela Bay Municipality (NMBM). In order to reach this goal, it was necessary to study the literature on the housing sector, especially as regards the impact between the external factors and the provision of low-income housing. A further supporting objective was to investigate and analyse the challenges in order to develop techniques and strategies for solving the challenges facing the NMBM in the provision of low-income housing. In order to address the reach problem and to fulfil the research objectives, an in-depth literature study was done. Empirical studies were also performed by means of face-to-face interviews and a questionnaire with the target group in the Housing Department of the NMBM. The literature and empirical study made it possible to identify underperformance and to recommend possible solutions for the challenges in the provision of low-income housing in the NMBM. These recommendations should be of value to all participants in the housing sector. From the investigation into the NMBM in the provision of low-income housing, the findings indicate that the constraints and challenges such as the housing backlog also exist in other parts of South Africa. Challenges such as availability of land in the NMBM can be considered to exist principally in the NMBM area. The new national policies and local government housing strategies should concur with the internationally accepted developmental approach. Recommendations were made with regard to sustainable development strategies, housing policies, finance and housing provision. Essential proposals were made, such as efficient financial support, and to train and improve certain unskilled staff in the NMBM. The study concludes with recommended techniques and strategies for the improvement of low-income housing in the NMBM, in order to overcome its challenges and to empower it on a sustainable basis.

- Description: The Kat River is an agricultural catchment that drains salt rich geology. Potential salinity impacts on ecological condition of the river were investigated. Monthly salt concentrations and flow discharges were monitored at ten sites along the Kat River below the Kat Dam. Monthly salt loads were computed to relate salinity to land use and ionic data used to assess the toxicity of major salts using the TIMS model. Concentration duration curves for sodium chloride were derived from flow concentration relationships, representing sodium chloride concentrations to which the aquatic ecosystem had been exposed. The ecological condition was assessed at nineteen sites using SASS5 biotic index over four seasons. Finally, the modelled instream salt concentrations and bioasessments were evaluated in terms of the modelled level of species protection afforded at different salt concentrations. Species Sensitivity Distributions (SSDs) were used for this exercise. There was a general downstream increase in salinity with the minimum concentrations recorded at the Fairbain tributary (84 mg/L) and maximum levels at the sewage outfall in Fort Beaufort (1222 mg/L). There was evidence that citrus irrigation upstream of Fort Beaufort increased salinisation. Sodium chloride, and to a lesser extent magnesium sulphate, were the dominant salts in the Kat River catchment, with the latter being more toxic. However these had little or no impact on the aquatic ecosystem. Flow-derived sodium chloride concentrations showed that both the Balfour and Blinkwater tributaries were in a fair/ poor condition. However with regard to ecological condition, it was demonstrated that the river is generally in a good state except for the Blinkwater River and the lower catchment. Degraded habitat condition at the Blinkwater was responsible for poor ecological condition. Integrating SSD derived classes, sodium chloride classes and ecological condition indicated that sodium chloride is a driver of ecological condition at the sewage treatment works and the subsequent site (only two of nineteen biomonitoring sites).

- Description: The thesis traces Southern African security dimensions from the Cold War and the period of apartheid in South Africa to the post-apartheid era. It makes an attempt to investigate the prospects of Southern Africa becoming a security community and the processes and practices underlying these efforts. Using the constructivist theory approach to international relations, the thesis argues that the preoccupation with principles of sovereignty and non-interference, a lack of political will and the absence of common values that could help SADC institute binding rules and decision-making are the main blocks that prevent the region from asserting itself as a security community. All these militate against the idea of mutual accountability among SADC member states and have a negative impact on the institutional and functional capacity of SADC. This also prevents SADC from dealing with the emerging non-military human security threats in the region. In consideration of this, the thesis argues that the idea of security community building in Southern Africa remains not only a regional issue, but also requires the involvement of extra-regional actors.

- Description: A voluminous literature attempts to explain the various channels of the monetary policy transmission mechanism through which central banks ultimately achieve price stability. However, most research focuses on interest rate pass-through and the demand for money phase, while there is limited research on the demand for credit. This study endeavours to contribute to the understanding of this neglected phase of monetary policy transmission by exploring the response of the real demand for bank credit by the private sector to changes in the real prime rate from 1990:1 to 2004:4 in South Africa. Firstly, the behaviour of the real prime rate in relation to the repo rate is explored using graphical analysis. The study observes that an increase in the repo rate causes an increase in the real prime rate, such that there is always a margin of three or four percentage points between the two rates. Secondly, using secondary data, the Johansen methodology is used to determine the relationship between the demand for bank credit and its determinants (GDP, inflation, real prime rate and real yield on government bonds). Two co-integrating relationships are found. The Gaussian errors from one co-integrating vector are used to model the Vector Error Correction Model, which provides the short-run dynamics and the long-run results, through the use of Eviews 5 software. The results of the study show that while all other variables are negatively related to the demand for bank credit in the long-run, GDP has a positive influence. In the short-run, yield on government bonds and inflation coefficients depict a positive association, while the coefficients of real prime rate and GDP are negative. The error correction coefficient is -0.32, which implies that a 32% adjustment to equilibrium happens in the demand for bank credit in a quarter and that the complete adjustment takes about three quarters to complete. Thirdly, the generalised impulse responses results indicate that the impact on the real prime rate affects the demand for bank credit from the first quarter. The study concludes that the real prime rate has a negative impact on the demand for credit both in the short-run and long-run.

- Description: Cosmopolitan and For Him Magazine (FHM) are, at present, both the most widely read and, therefore, the most popular "white" consumer magazines in South Africa. They both appeal to young audiences of between 18 and 34 years of age, approximately, and target middle-class, educated groups of readers. My interest in Cosmopolitan and FHM lies in their ability to influence and shape their readers' actions, values, identities and relationships, in particular with the other gender. My analysis is focused on the cover pages and the Editor's letters of six copies of each magazine, ranging from April to September 2003, providing me with a corpus of 12 cover pages and 12 Editor's letters. I adopt a critical perspective through the use of Fairclough's (1989) Critical Discourse Analysis, supported by Mills (1995) Feminist Stylistics, McLoughlin's (2000) textual analysis of cover pages and Kress & van Leeuwen's (1996) visual analysis tools. By combining these different methodologies my research falls into what is newly termed Feminist Critical Discourse Analysis (Lazar 2005). The cover page analyses used primarily McLoughlin and Kress & van Leeuwen and provides an element of pure genre analysis, while the analysis of the Editor's letters were subject to Fairclough's three inter-related stages of analysis, namely: a Description of the formal textual elements of the letters, an Interpretation which analyses the processes of text production and interpretation, and lastly an Explanation of the socio-historical context. Through an analysis of these magazines, whose interests are being served and how the readers are shaped and positioned by the magazines can be identified. My analyses revealed conflicting discourses within each magazine, however it was Cosmopolitan that revealed more tension and conflict in terms of identifying and representing women, while FHM subscribed, for the most part, uniformly to the "new lad" ideology. However, while Cosmopolitan attempted to show a forward-thinking and emancipatory view of the roles of men and women in society, both magazines covertly sustain patriarchal dominance and hegemonic masculinity. In conclusion, I reveal the need for consumers of the mass media to become more critically aware of the ideologies that are promoted through the differing tools of the media and that only through this critical awareness can any further movement towards equal relations between men and women be made. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Previously, our workplaces were characterised by serious hardships emanating from labour laws which did not always cater for all areas of the employment relationship. South African female employees were without a clear legitimate remedial right precluding any severe violation and infringement to their fundamental rights resulting from their pregnancy; a task they did not opt for in the first place, but was instead, naturally imposed on them as a result of their gender category. Undoubtedly, many female employees were victims of unfair discrimination. The legislature therefore saw it fit to democratise the workplace by making rapid statutory interventions. As a result, a number of significant changes in various spheres of our labour laws were brought in. Amongst the greatly notable valuable changes was the introduction of the Employment Equity Act 55 of 1998. This piece of legislation has generally reformed our industrial society by bringing in the elimination of unfair discrimination and thereby enhancing the principle of equity in the workplace. The act has further touched a place within hearts of female employees for fear of discrimination as a result of their pregnancy status or any reasons related to their pregnancy. The act further codified Industrial Court decisions that were already established under the discrimination law jurisprudence from the Labour Relations Act 28 of 1956. The application of the provisions of the Act has made the employment relationship no longer to be a comfort zone for employers. These general changes to the law also impact on the dismissal law regime. The purpose of this treatise is to give an overview of the applicable legislation and contributions made by the Labour Courts in developing pregnancy dismissal and discrimination law. The Labour Courts have handed down few judgements that have helped in clarifying the provisions of both the current Labour Relations Act and the Employment Equity Act around the topic. One should hasten to say that this has never been a smooth process by the courts. It is further shown in this treatise that some of the court decisions were not well accepted in the light of other important considerations, such as the equality provisions of the Constitution. For the purpose of effectively dealing with this topic, this treatise contains a discussion of the historical context of discrimination law in the form of common-law position, and the discrimination law before the Bill of Rights and the Constitution. It then endeavours to identify the legislative provision of the Act when it comes to discrimination law provisions. At the same time the important court decisions that were made are identified and examined.

- Description: Previously, our workplaces were characterised by serious hardships emanating from labour laws which did not always cater for all areas of the employment relationship. South African female employees were without a clear legitimate remedial right precluding any severe violation and infringement to their fundamental rights resulting from their pregnancy; a task they did not opt for in the first place, but was instead, naturally imposed on them as a result of their gender category. Undoubtedly, many female employees were victims of unfair discrimination. The legislature therefore saw it fit to democratise the workplace by making rapid statutory interventions. As a result, a number of significant changes in various spheres of our labour laws were brought in. Amongst the greatly notable valuable changes was the introduction of the Employment Equity Act 55 of 1998. This piece of legislation has generally reformed our industrial society by bringing in the elimination of unfair discrimination and thereby enhancing the principle of equity in the workplace. The act has further touched a place within hearts of female employees for fear of discrimination as a result of their pregnancy status or any reasons related to their pregnancy. The act further codified Industrial Court decisions that were already established under the discrimination law jurisprudence from the Labour Relations Act 28 of 1956. The application of the provisions of the Act has made the employment relationship no longer to be a comfort zone for employers. These general changes to the law also impact on the dismissal law regime. The purpose of this treatise is to give an overview of the applicable legislation and contributions made by the Labour Courts in developing pregnancy dismissal and discrimination law. The Labour Courts have handed down few judgements that have helped in clarifying the provisions of both the current Labour Relations Act and the Employment Equity Act around the topic. One should hasten to say that this has never been a smooth process by the courts.

- Description: Future Search is a new concept in Namibia. This study looks at the application of a Future Search Conference (FSC) with the Nursing Board of Namibia with a view to investigating participants' experiences and perceptions of the FSC as an organizational change strategy. I conducted a case study in the interpretive paradigm, since I was interested in understanding the subjective experience and individual perceptions of five respondents with regard to the FSC. To obtain in-depth information on how participants felt about the FSC, I employed two data gathering tools: un-structured individual interviews and observation. The findings confirmed that the Future Search is a new concept in the Ministry of Health in particular and in Namibia as a whole. Participants are of the opinion that leaders and managers are key figures in the success or failure of the Future Search. They showed a tremendous interest in the process and are willing to embrace and master the tool so they could try it in their various areas of work. Emphasis was put on the need to get the FSC introduced to leaders and higher management cadres on a wider scale, because they are decision makers and can decide whether or not the Future Search could be institutionalized. This study concludes with an appeal from respondents to be exposed to the Future Search again in a better time frame than the short time we had.

- Description: Today, information is considered a commodity and no enterprise can operate without it. Indeed, the information and the supporting technology are pivotal in all enterprises. However, a major problem being experienced in the business environment is that enterprise risk cannot be managed effectively because business and information-related risk are not congruently aligned with risk management terminology and practices. The business environment and information technology are bound together by information. For this reason, it is imperative that risk management is synergised in the business, ICT (Information and Communication Technology) and information environments. A thorough, all inclusive, risk analysis exercise needs to be conducted in business and supporting environments in order to develop an effective internal control system. Such an internal control system should reduce the exposure of risk and aid the safeguarding of assets. Indeed, in today’s so-called information age, where business processes integrate the business and ICT environments, it is imperative that a unary internal control system be established, based on a holistic risk management exercise. To ensure that the enterprise, information and ICT environments operate free of the risks that threaten them, the risks should be properly governed. A model, EPiRISMM (Enterprise Information Risk Management Model) is proposed that offers to combine risk management practices from an ICT, information, governance, and enterprise perspective because there are so many overlapping aspects inherent in them. EPiRISMM combines various well-known standards and frameworks into one coherent model. By employing EPiRISMM, an enterprise will be able to eliminate the traditional segmented approach of the ICT department and thus eliminate any previous discontinuity in risk management practices.

- Description: The population structure and feeding dynamics of the hyperiid amphipod, Themisto gaudichaudii, was investigated during two cruises of the South African National Antarctic Programme conducted in the Indian sector of the Polar Frontal Zone during austral autumn (April) 2004 and 2005. During the 2004 cruise the frontal features that delimit the PFZ converged to form a single distinctive feature. In 2005, the research cruise was conducted in the vicinity of a cold-core eddy which was spawned from the Antarctic Polar Front. Total mesozooplankton abundance and biomass during the 2004 study ranged from 55.19 to 860.57 ind. m⁻³, and from 2.60 to 38.42 mg dwt m⁻³, respectively. In 2005 the abundance and biomass ranged from 23.1 to 2160.64 ind. m⁻³, and from 0.76 to 35.16 mg dwt m⁻³, respectively. The mesozooplankton community was numerically dominated by copepods, pteropods, and ostracods during both surveys. The abundance and biomass of Themisto gaudichaudii in the region of investigation was < 0.2 ind. m⁻³ (range 0.01 to 0.15 ind. m⁻³) and < 0.06 mg dwt m⁻³ (range 0.02 to 0.06 mg dwt m⁻³) during 2004, while in 2005 the abundance and biomass of the amphipod ranged from < 0.01 to 0.2 ind. m⁻³ and < 0.01 to 0.04 mg dwt m⁻³, respectively. These values correspond to < 1% of the total mesozooplankton abundance and biomass during both surveys. T. gaudichaudii exhibited no significant spatial patterns in abundance, biomass and total length during both 2004 and 2005 (p > 0.05 in all cases). A key feature of the two investigations was the virtual absence of juveniles (total length < 15 mm) among the amphipod population, supporting the suggestion that they exhibit strong seasonal patterns in reproduction. Gut content analysis during both years indicated that for both the male and female amphipods’, copepods were the most prevalent prey species found in stomachs, followed by chaetognaths and pteropods. Results of electivity studies indicate that T. gaudichaudii is an opportunistic predator, generally feeding on the most abundant mesozooplankton prey. Results of in vitro incubations indicated that the total daily feeding rate of T. gaudichaudii during 2004 ranged from 11.45 to 20.90 ind. m⁻³ d⁻¹, which corresponds to between 0.12 and 1.64% of the total mesozooplankton standing stock. In 2005, the feeding rate ranged between 0.1 and 1.73% of the total mesozooplankton standing stock. The low predation impact of T. gaudichaudii during this study can be related to their low abundances and high interannual variability throughout the region of investigation.

- Description: For a long time the rights of disabled persons have been ignored worldwide. A major obstacle faced by disabled persons is discrimination in the workplace. Due to the development of a social approach to disability and the efforts of the Disability Rights Movement, legislation has been passed throughout the world to improve this dire situation. The thesis considers the efficacy of some of these statutes. It is concluded that stigma and negative stereotypes remain a constant hurdle in overcoming discrimination. The forthcoming UN Disability Convention is demonstrative of the recognition of the importance of the needs and rights of disabled people. The convention proposes some innovative measures to overcome stigma and stereotyping. Mental health problems constitute one of the leading causes of disability. The thesis explores how people with mental health problems fit within the concept of people with disabilities and whether they are included in anti-discrimination legislation and affirmative action measures. Special attention is given to statutory definitions of disability, the different forms of discrimination and the concept of reasonable accommodation. A comparative approach is taken to analyse how South Africa's disability law measures up against that of Britain and Australia in terms of its substantive provisions and enforcement thereof. In considering the South African position American and Canadian jurisprudence is consulted in order to aid in interpretation. It is concluded that although South Africa has a comparatively good legislative framework, it is held back by an overly restrictive and medically focused definition of disability. As a result many individuals with mental health difficulties, desirous of obtaining and retaining employment may be excluded from protection against discrimination in the workplace. It is argued that it will be necessary either to amend the Employment Equity Act or for the courts to adhere strictly to the concept of substantive equality in order to ensure that the rights and dignity of people with mental health difficulties are adequately protected.

- Description: September 11, 2001 presented the world with events that challenged its conception of reality and called into question current ideologies. In order to make sense of the attacks, people turned to the media for information and interpretation. My interest lies in the media’s role in shaping ideologies as a result of the events of September 11, 2001. I focus on the newspaper editorial because it, in particular, functions not only to report the news but also to interpret the news for the reader. My analysis is centred on the first reaction to the events in five ‘core’ editorials drawn, respectively, from an American, British, South African, Zimbabwean and Kenyan newspaper. The specific focus, in each case, is the representation and evaluation of social actors, the events themselves and the schematic structure of the editorial. I adopt a critical perspective through the use of Critical Discourse Analysis, supported by Systemic Functional Grammar and APPRAISAL. This perspective involves three inter-connected stages of analysis: a Description of the formal discourse properties of each editorial; an Interpretation of the prevailing situational context; and an Explanation of the sociohistorical context in each case. Language, being a form of social practice, is a means by which power relations in society are reproduced or contested (Janks 1997). By analysing the editorials’ discourse I identify whose interests are being served and how each text positions a reader’s attitudes and opinions. My analysis reveals the fact that the editorials distinguish between “us” and “them” groups for the purposes of advancing and confirming in-group ideologies and agendas. This is achieved in each case through comparing the paper’s ideology with the opposing ideology, which is presented as deviant and unsupportive of the in-group. My analysis of the African editorials, in particular, further reveals the exploitation of this division for the purposes of promoting and interpreting local political and social issues. Examination of the processes and conditions surrounding the production of the editorials shows how they are significantly influenced and constrained by the ideologies of both the writer and newspaper owner as well as by the situational context within which they were written. My analysis of the schematic structure of the editorials, in line with Bolivar (1994), reveals consistent use of three-part structures by which editorial opinions are evaluated. In concluding I provide suggestions, based on my research, for how critical language awareness can inform media education at high school level in South Africa. I argue that students should be equipped with tools, such as those I employed, to critically analyse and uncover how language is used to promote ideologies in the editorial of newspapers.

- Description: The use of electronic mail (email) has evolved from sending simple messages to task delegation and management. Most mail clients, however, have not kept up with the evolution and as a result have limited task management features available. On the other hand, while issue tracking systems offer useful task management functionality, they are not as widespread as emails and also have a few drawbacks. This thesis reports on the exploration of the integration of the ubiquitous nature of email with the task management features of issue-tracking systems. We explore this using simple ad-hoc as well as semi-automated tasks. With these two working together, tasks can be delegated from email clients without needing to switch between the two environments. It brings some of the benefits of issue tracking systems closer to our email users.The system is developed using Microsoft VisuaI Studio.NET. with the code written in C#. The eXtreme Programming (XP) methodology was used during the development of the proof-of-concept prototype that demonstrates the integration of the two environments, as we were faced at first with vague requirements bound to change, as we better understood the problem domain through our development. XP allowed us to skip an extended and comprehensive initial design process and incrementally develop the system, making refinements and extensions as we encountered the need for them. This alleviated the need to make upfront decisions that were based on minimal knowledge of what to expect during development. This thesis describes the implementation of the prototype and the decisions made with each step taken towards developing an email-based issue tracking system. With the two environments working together, we can now easily track issues from our email clients without needing to switch to another system. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

The ICC made its debut at a time when States were routinely accused of non-compliance with international law, particularly international criminal law. Due to perennial concerns over the protection of State sovereignty, an ingenious system of allocation of competencies between States and the ICC was evolved. This is embodied by the principle of complementarity. At the heart of complementarity is an arrangement by which States Parties to the Rome Statute of the ICC are regarded as the prime fora for the prosecution of crimes of grave concern to the international community. In the event of inaction, however, the ICC is mandated to wrest specific cases from the jurisdiction of national courts and try them. In effect, a carrot-and-stick mechanism has been built into the Rome Statute to induce States to comply with the Statute. This thesis examines the principle of complementarity from a theoretical perspective, bearing in mind contemporary international law structures and institutions. A better understanding of the theoretical assumptions of complementarity, it is suggested, will foster a more effective application of the tenets of the Rome Statute within the municipal system. The thesis argues that complementarity is a catalyst for implementation of the Rome Statute only to the extent to which it alters or re-defines well established and encumbering procedures and norms within the municipal system. In this regard, although South Africa’s status of constitutional democracy may be reason to expect that the obligations imposed by the Rome Statute will be observed, that very fact may increase the inclination to preserve the “baseline of conduct” rather than be swayed by the Rome Statute. An illustrative excursion into South African rules and norms is undertaken, after which the argument is advanced that not much change has been effected to the South African legal landscape through implementation of the Rome Statute. The sole exception to this is the issue of prosecutorial discretion. On this, the South African legislature has uniquely crafted a mechanism for ensuring accountability, presumably with a view to ensuring that South Africa is always able to prosecute the crimes concerned. However, the thesis cautions against complacency, arguing that the tension between national law and international obligations may yet play itself out, owing to insufficient attention to the role of national courts in giving effect to the Rome Statute. The act of implementation may be a response to stimuli such as the perceived need to avoid civil liability for international crimes, or the general inertia of implementing human rights instruments. Therefore, the carrot-and-stick mechanism may be lacking in the compulsive qualities it is presumed to have. Through an exploratory survey of South African law, the thesis illustrates that prosecutorial accountability is the major factor in determining whether a State has fully complied with is obligations under the Rome Statute. However, it also points out that the way courts of law apply the new norms in municipal systems in the future will be crucial.
