- Description: The main objective of this study was to assess the relationship between organisational climate and organisational commitment within the Information Technology department of a South African Telecommunications company. Firstly, the research considered the organisational climate from a qualitative perspective. Research interviews that were based on organisational climate literature were performed with 4 members of the relevant department. Qualitative data analysis revealed several themes. The themes highlighted include: perceived ineffective structure and decision-making; lack of mistake tolerance; risk aversion by employees; recognition and reward systems perceived to be inadequate; performance management is perceived to be ineffective and inadequate; Employee Share Options Program (ESOP) perceived to have a negative influence on employee behaviours; the nature of the social environment perceived to be unfriendly; low level of knowledge and skills sharing; inadequate human resource management practices; These findings highlight the importance of certain aspects within the environment that influence employee perceptions. Organisational climate literature suggests that organisational climate has various behavioral influences and its consideration is essential in the effective functioning of the organisation. Secondly, the research considered the relationship between organisational climate and organisational commitment within the relevant department. The Patterson et al. (2005) Organisational Climate Measure (OCM®) and Meyer and Allen (1991) Organisational Commitment Questionnaire (OCQ) were used to assess the relationship between organisational climate and organisational commitment, respectively. Significant correlations were found between integration, pressure to produce, innovation, supervisory support, reflexivity, clarity, involvement, autonomy, welfare and tradition, and both affective and normative commitment, Training was only significantly correlated to affective commitment. No significant correlations were found with continuance commitment.

- Description: Central to this research, 40 kDa Heat shock proteins (Hsp40s) are known to partner (or cochaperone) 70 kDa Heat shock proteins (Hsp70s), facilitating the selection and transfer of protein substrate to Hsp70 and the stimulation of the protein folding ability of Hsp70. Members of the diverse Hsp70-Hsp40 protein complement of Plasmodium falciparum have been implicated in the cytoprotection of this malaria parasite, and are thought to facilitate the protein folding, assembly and translocation tasks required by the parasite to commandeer the infected human erythrocyte subsequent to invasion. In particular, the parasite has evolved an expanded and specialised 43- member suite of Hsp40 proteins, 19 of which bear an identifiable export motif for secretion into the infected erythrocyte cytoplasm where they potentially interact with human Hsp70. Although type I Hsp40 proteins are representative of typical regulators of Hsp70 activity, only two of these proteins are apparent in the parasite’s Hsp40 complement. These include a characteristic type I Hsp40 termed PfHsp40, and a larger, atypical type I Hsp40 termed Pfj1. Both Hsp40 proteins are predicted to be parasite-resident and are most likely to facilitate the co-chaperone regulation of the highly abundant and stress-inducible Hsp70 homolog, PfHsp70-I. In this work, the co-chaperone functionality of PfHsp40 and Pfj1 was elucidated using in vivo and in vitro assays. Purified recombinant PfHsp40 was shown to stimulate the ATPase activity of PfHsp70-I in in vitro single turnover and steady state ATPase assays, and co-operate with PfHsp70-I in in vitro aggregation suppression assays. In these in vitro assays, heterologous partnerships could be demonstrated between PfHsp70-I and the human Hsp40, Hsj1a, and human Hsp70 and PfHsp40, suggesting a common mode of Hsp70-Hsp40 interaction in the parasite and host organism. The functionality of the signature Hsp40 domain, the Jdomain, of Pfj1 was demonstrated by its ability to replace the equivalent domain of the A. tumefaciens Hsp40, Agt DnaJ, in interactions with the prokaryotic Hsp70, DnaK, in the thermosensitive dnaJ cbpA E. coli OD259 deletion strain. An H33Q mutation introduced into the invariant and crucial HPD tripeptide motif abrogated the functionality of the J-domain in the in vivo complementation system. These findings provide the first evidence for the conservation of the prototypical mode of J-domain based interaction of Hsp40 with Hsp70 in P. falciparum. Immunofluorescence staining revealed the localisation of PfHsp40 to the parasite cytoplasm, and Pfj1 to the parasite cytoplasm and nucleus in cultured intraerythrocytic stage P. falciparum parasites. PfHsp70-I was also shown to localise to the parasite cytoplasm and nucleus in these stages, consistent with the literature. Overall we propose that PfHsp40 and Pfj1 co-localise with and regulate the chaperone activity of PfHsp70-I in P. falciparum. This is the first study to identify and provide evidence for a functional Hsp70-Hsp40 partnership in P. falciparum, and provides a platform for future studies to elucidate the importance of these chaperone partnerships in the establishment and survival of the parasite in the intraerythrocytic-stages of development.

- Description: This study is about the employee perceptions of the effect of the Quality Management System intervention that was implemented at one of South Africa’s government departments. This organisation’s Quality Management System being one of the first in the government or public sector in South Africa to be implemented, creates the possibility for this Quality Management System model to be used to develop Quality Management Systems in other departments or organisations belonging to the government or the public sector in South Africa and the Southern African region. According to Madu & Kuei (1995), Quality Management System describes a situation where all business functions are involved in a process of continuous quality improvement. This implies that the development and implementation of Quality Management Systems in government departments and the public sector will improve the quality of services delivery. The findings of this study indicated that a Quality Management System can be used to improve the level of service delivery in the public sector. The Quality Management System should be planned developed and implemented over a period of time in five phases (i) Phase 1 - Determination of the scope of Quality Management System implementation (ii) Phase 2 – Training (iii) Phase 3 – Development of Procedures (iv) Phase 4 – Pilot implementation of procedures (v) Phase 5 – Evaluation of Quality Management System and rollout. It usually takes three or more years to establish an organisation-wide Quality Management System, although technical improvement to the workflow can be as quickly as six to eight months. And finally, for the Quality Management System to be developed, implemented and maintained successfully, Maximisation of Performance objectives, Good Leadership, Motivation of staff, Implementation of Change Management, Employee Involvement, Long-term Top Management Commitment, Provision of Training, Introduction of Quality Improvement Projects, Measuring Quality Management System Progress and Reward Accomplishment, are the fundamental concepts or principles that should be considered.

- Description: Fisheries management regulations for dusky kob Argyrosomus japonicus, an important commercial and recreational fisheries species, have failed and the stock is considered collapsed. It is important to take an ecosystems approach to management which includes understanding the effect of environmental factors on recruitment, abundance and distribution. The distribution of early juveniles (20-150 mm TL) in the wild appears to be restricted to the upper reaches of estuaries at salinities below 5 psu. Food availability could not explain the distribution of early juveniles. The aim of this study was to investigate the role of salinity on the distribution of early juvenile dusky kob (<150 mm TL) by examining physiological responses of juveniles exposed to a range of salinities under laboratory conditions. The hypothesis was that the physiological functioning of early juveniles would be optimised at the reduced salinities which they naturally occur at. The objectives of this study were to investigate the effect of salinity on: i) plasma osmolality; ii) growth, food conversion ratio and condition factor; and iii) gill histology with emphasis on chloride cell size and number. A preliminary study was undertaken to determine whether the use of 2-phenoxyethanol had an effect on plasma osmolality. Juveniles pithed prior to blood sampling were used as the control. Plasma osmolality was not affected by exposure or duration of exposure (2, 4, 6, 8, 10 min) to 2-phenoxyethanol. The ability of teleosts to regulate plasma osmolality over a wide range of salinities indicates their degree of ‘physiological euryhalinity’. Plasma osmolality of juveniles exposed to 5, 12 and 35 psu was measured every two weeks over a total of six weeks. Although juveniles were able to regulate plasma osmolality over the duration of the experiment, plasma osmolality at 5 and 12 psu was significantly lower than in fish maintained at 35 psu. Growth is used as an indicator of the relative energy used for osmoregulation at different salinities, as the energy used for osmoregulation becomes unavailable for growth. A nineweek growth experiment was conducted on juveniles exposed to 5, 12 and 35 psu. Juveniles grew and survived at all three salinities. However, growth of juveniles at 5 psu was significantly lower than at 12 and 35 psu. Other than a significantly greater weight gain at 35 psu relative to 12 psu, there was no significant difference in specific growth and length gain between juveniles at 12 and 35 psu. Food conversion ratio and condition factor at 12 and 35 psu were not significantly different, but food conversion ratio and condition factor at 5 psu was significantly greater and lower than at 35 psu respectively. In fish, gills are considered the major organ involved in osmoregulation. Within the gills, chloride cells are the predominant site of ion exchange which is driven by the Na⁺, K⁺- ATPase enzyme. Gill samples of juveniles exposed to 5, 12 and 35 psu for six weeks were examined histologically using light microscopy. Chloride cells of juveniles maintained at 5 psu were significantly more abundant than in juveniles at 12 and 35 psu. Chloride cells of juveniles at 5 psu were significantly larger than in juveniles kept at 12 psu, but not significantly different to those of juveniles kept at 35 psu. The ability of the juvenile fish to regulate plasma osmolality indicates that they are 'physiologically euryhaline', but the reduced growth and proliferation of chloride cells at 5 psu suggests that energy expenditure for osmoregulation is increased at hypoosmotic salinities. Salinity induced physiological responses could therefore not explain the natural distribution of early juvenile dusky kob and it is proposed that other environmental factors (e.g. temperature) are also important. It is also hypothesised that the high conductivity of an estuary in South Africa, to which our understanding is limited, may negate the effect of reduced salinity. Although freshwater input into estuaries is an important factor, further investigations to explain the distribution and abundance of early juveniles is required to make management recommendations. Dusky kob is also becoming an increasingly popular aquaculture species in South Africa. In this regard, early juvenile dusky kob can be grown at salinities as low as 12 psu without negatively affecting growth and production.

- Description: This study focused on a topic at the intersection of two contexts, namely curriculum responsiveness and industrial/organisational psychology (IOP). The rationale for this study is based on two considerations. Firstly, a review of the IOP curricula offered at ten prominent South African universities revealed little overlap. This suggests that academic departments are not guided by shared principles when they implement decisions about the content or sequencing of curriculum content. Secondly, the Department of Education urges academics to design curricula that are relevant and responsive to contemporary conditions. These two considerations motivated the investigation of the following research question: What key performance areas (KPAs) do employers specify when they advertise positions suitable for IOP graduates? The investigation had two aims, namely (a) to systematically analyse the KPAs specified in job advertisements and (b) to compile KPA templates that may be used by IOP departments who wish to revise or transform their curricula. The research design of this study has five characteristics, namely that it is: (a) qualitative, (b) naturalistic, (c), descriptive, (d) applied, and (e) strategic. The study employed a purposive sampling strategy that involved the collection of documentary data (job advertisements aimed at recruiting IOP graduates) over a 52-week period (N=1115). The data was content analysed by means of a six-step documentary analysis method. Specific strategies were employed to enhance the validity of the findings. These strategies focused on credibility, transferability, dependability, and confirmability. Similarly, the ethical standing of the investigation was promoted by addressing four considerations, namely autonomy and respect for dignity, non-maleficence, beneficence, and justice. The data analysis procedure produced comprehensive and detailed qualitative descriptions of (a) 21 occupational categories, (b) 4070 KPA themes and (c) 84 KPA clusters. In addition, the number of occupational categories, KPA themes and KPA clusters were recorded and interpreted. In addition, the data analysis procedure produced comprehensive KPA templates that IOP departments may find useful. The templates reflect the KPAs specified by advertisements aimed at recruiting IOP graduates for a range of occupational categories and were designed to be used as benchmarks against which the economic responsiveness of curricula can be compared.

- Description: With the move towards global and multi-national companies, information technology infrastructure requirements are increasing. As the size of these computer networks increases, it becomes more and more difficult to monitor, control, and secure them. Networks consist of a number of diverse devices, sensors, and gateways which are often spread over large geographical areas. Each of these devices produce log files which need to be analysed and monitored to provide network security and satisfy regulations. Data compression programs such as gzip and bzip2 are commonly used to reduce the quantity of data for archival purposes after the log files have been rotated. However, there are many other compression programs which exist - each with their own advantages and disadvantages. These programs each use a different amount of memory and take different compression and decompression times to achieve different compression ratios. System log files also contain redundancy which is not necessarily exploited by standard compression programs. Log messages usually use a similar format with a defined syntax. In the log files, all the ASCII characters are not used and the messages contain certain "phrases" which often repeated. This thesis investigates the use of compression as a means of data reduction and how the use of semantic knowledge can improve data compression (also applying results to different scenarios that can occur in a distributed computing environment). It presents the results of a series of tests performed on different log files. It also examines the semantic knowledge which exists in maillog files and how it can be exploited to improve the compression results. The results from a series of text preprocessors which exploit this knowledge are presented and evaluated. These preprocessors include: one which replaces the timestamps and IP addresses with their binary equivalents and one which replaces words from a dictionary with unused ASCII characters. In this thesis, data compression is shown to be an effective method of data reduction producing up to 98 percent reduction in filesize on a corpus of log files. The use of preprocessors which exploit semantic knowledge results in up to 56 percent improvement in overall compression time and up to 32 percent reduction in compressed size. , TeX , pdfTeX-1.40.3

- Description: Trophodynamics of carnivorous zooplankton in the region of the Subtropical Convergence (STC) in the Indian sector of the Southern Ocean was investigated during austral autumn (April 2007) as part of the first cruise of the Southern Ocean Ecosystem Variability Study. Within the region of the study, the STC was well defined by the 14°C surface isotherm which separated the Agulhas Return Current and Subtropical water in the north from Sub-Antarctic waters to the south. Total average abundance (3.89 ± 5.46ind 100m-3) and biomass (0.14 ± 0.27mg Dwt 100m-3) of carnivorous zooplankton south of the front were significantly higher than the total average abundance (1.33 ± 1.81ind 100m-3) and biomass (0.03 ± 0.05mg Dwt 100m-3) north of the front (p<0.001). There were no significant correlations between the selected physico-chemical (temperature and salinity) and the biological (mesozooplankton abundance and biomass) variables and the total abundance and biomass of the carnivorous zooplankton during the investigation (p>0.05 in all cases). There was no evidence of enhanced biomass and abundance values at stations occupied in the immediate vicinity of the front. Total average carnivorous zooplankton abundance was dominated by chaetognaths (Eukrohnia hamata Möbius 1875, Sagitta gazellae Ritler-Záhony 1909 and S. zetesios Fowler 1905) and euphausiids (Nematoscelis megalops Sars 1883, Euphausia longirostris Hansen 1908 and E. spinifera Sars 1883), which contributed up to 86.58 ± 32.91% of the total counts. The total average biomass was dominated by euphausiids and amphipods (Themisto gaudichaudii Guérin-Méneville 1825, Phronima sedentaria Forsskål 1775 and Vibilia armata Bovallius 1887) which contributed up to 71.45 ± 34.85% of the total counts. In general the populations of both the euphausiids and amphipods were dominated by females while the chaetognaths were dominated by juveniles. Numerical analysis identified two major zooplankton groupings within the survey area which did not coincide with the water masses within the survey area. The SIMPER procedure of the PRIMER package indicated differences between the groups were mainly attributed to changes in the abundance of the numerically dominant species rather than the presence or absence of individual species. The absence of any significant spatial patterns in the distribution of the carnivorous zooplankton suggests that the STC did not act as a biogeographical barrier during the present study. The mean feeding rates of the chaetognaths E. hamata, S. gazellae and S. zetesios were 1.82 ± 0.85prey d-1, 3.63 ± 2.08prey d-1 and 2.18 ± 0.59prey d-1, respectively. These rates correspond to a combined predation impact equivalent to <5% of the mesozooplankton standing stock or <10% of the mesozooplankton secondary production. Mesozooplankton, comprising mainly copepods was the dominant prey in the guts of the three chaetognath species. Total predation impact of the euphausiids, chaetognaths and amphipods, estimated using published daily ration data, on the mesozooplankton standing stock and secondary production ranged from 0.01% to 1.53% and from 0.03% to 30.54%, respectively. Among the carnivorous zooplankton, chaetognaths were generally identified as the dominant predators of mesozooplankton. Low predation impact of selected carnivorous zooplankton suggested that these organisms contributed little to the vertical carbon flux within the region of investigation during the study.

- Description: This work examines the use of nonhuman animals in the farming industry and seeks to understand why this practice takes place and what supports its continuation. The research is approached from a critical realist perspective and after a description of past and current practices in the industry, it uses abduction and retroduction to determine the essential conditions for the continuation of the phenomenon of nonhuman animal farming. One essential condition is found to be the existence of negative discourses relating to nonhuman animals and this aspect is examined in more detail by analyzing a corpus of texts from a farming magazine using Critical Discourse Analysis. Major discourses which were found to be present were those of production, science and slavery which construct the nonhumans respectively as objects of scientific investigation, as production machines and as slaves. A minor discourse of achievement relating to the nonhumans was also present. Further analysis of linguistic features examined the way in which the nonhumans are socially constructed in the discourses. Drawing on work in experimental psychology by Millgram, Zimbardo and Bandura it was found that the effects of these discourses fulfil many of the conditions for bringing about moral disengagement in people thus explaining why billions of people are able to support animal farming in various ways even though what happens in the phenomenon is contrary to their basic ethical and moral beliefs.

- Description: The failure rate of small business initiatives in South Africa is phenomenal, and much is needed to unravel the causes contributing to such failures. Yet small businesses are playing a vital part in our global economy and in particular in terms of job creation and poverty eradication. There are internal as well as external factors that play a significant role in determining the success of these small businesses. In South Africa much emphasis is placed by national, provincial and local governments on small and medium enterprises (SMEs) to drive wealth creation and black economic empowerment. Therefore, an investigation into the factors contributing to the success and failure of SMEs is of vital importance. The South African government’s poverty eradication strategy, which is driven by the Department of Trade and Industry (DTI), allocated funds for job creation programmes as a method to combat poverty and more importantly, to develop young entrepreneurs. Among the seven departments mandated by DTI was the Department of Social Development. Since the birth of the new democracy, this department has transformed from offering a traditional remedial method of service delivery to an integrated developmental approach. This approach included extensive community work, which includes job creation and economic empowerment through the establishment of small businesses. Given the availability of funding, the inability to spend fiscal budgets as per allocation as well as the charity element of receiving involved, it is important to explore whether factors contributing to the success of these SMEs are any different to the traditional business strategies. In this study, the researcher gave special consideration to the social capital element and its contribution in the context of community support as well as the ability of SMEs to become sustainable business ventures over time. The research study aims to highlight unique factors contributing to the success and failures of SMEs established by the Department of Social Development and in doing so hopes to manifest an improved understanding of the management of these SMEs. In chapter one, the researcher gives a brief description of the activities of the Department of Social Development and its mandate to establish SMEs for job creation. A brief explanation regarding the context of the problem that was investigated is also given. Chapter two provides a detailed theoretical overview of the study, focusing in particular on factors contributing to the success and failure of small businesses. In chapter three, the research design and the various instruments used are discussed. Here, emphasis is placed on procedural issues and ethical considerations. The validity and reliability of the research is strongly motivated. In chapter four the research results are discussed. Chapter five aims to discuss the findings of the research with reference to the theoretical overview outlined in chapter two. Lastly, chapter six makes recommendations to the various stakeholders who may benefit from this research. These recommendations are the most important objectives of the research and should add value with regards to the management of SMEs in future, with special reference to the Department of Social Development in the Eastern Cape.

Myth, Music & Modernism: the Wagnerian dimension in Virginia Woolf's Mrs Dalloway and the waves and James Joyce’s Finnegans Wake

- Description: The study of Wagner's influence on the modernist novel is an established field with clear room for further contributions. Very little of the criticism undertaken to date takes full cognizance of the philosophical content of Wagner's dramas: a revolutionary form of romanticism that calls into question the very nature of the world, its most radical component being Schopenhauer's version of transcendental idealism. The compatibility of this doctrine with Wagner's earlier work, with its already marked privileging of myth over history, enabled his later dramas, consciously influenced by Schopenhauer, to crown a body of work greater than the sum of its parts. In works by Virginia Woolf and James Joyce, the "translation" of Wagnerian ideas into novelistic form demonstrates how they might be applied in "real life". In Mrs Dalloway, the figure of Septimus can be read as partly modelled on Wagner's heroes Siegfried and Tristan, two outstanding examples of the opposing heroic types found throughout his oeuvre, whose contrasting attributes are fused in Septimus's bipolar personality. The Wagnerian pattern also throws light on Septimus's transcendental "relationship" with a woman he does not even know, and on the implied noumenal identity of seemingly isolated individuals. In The Waves, the allusions to both Parsifal and the Ring need to be reconsidered in light of the fact that these works' heroes are all but identical (a fact overlooked in previous criticism); as Wagner's solar hero par excellence, Siegfried is central to the novel's cyclical symbolism. The Waves also revisits the question of identity but in a more cosmic context – the metaphysical unity of everything. In Finnegans Wake, the symbolism of the cosmic cycle is again related to the Ring, as are Wagner's two heroic types to the Shem / Shaun opposition (the Joyce / Woolf parallels here have also been overlooked in criticism to date). All three texts reveal a fascination with the two contrasting faces of a Wagnerian hero who embodies the dual nature of reality, mirroring in himself the eternal rise and fall of world history and, beyond them, the timeless stasis of myth.

- Description: The enormous social, economic, and political government-led societal transformation South Africans have experienced over the past 15 years have brought about numerous societal and identity changes. The aim of the present study was to explore how dominant (White participants) and non-dominant (Black participants) groups experiencing the government-led societal transformation process deal with perceptions of intergroup differences based on Social Identity Theory (Tajfel & Turner, 1979, 1986) and related field research. Social Identity Theory predicts that in the presence of intergroup differences group members irrespective of their status position will apply identity management strategies to either improve or maintain their status position. The relationships between perceptions of intergroup relations and identity management strategies as proposed by Social Identity Theory were tested studying 170 second year Rhodes University psychology students. Sixty participants indicated themselves as Black South Africans (representing non-dominant group) and 110 participants identified themselves as White South Africans (dominant group). The results revealed that dominant and non-dominant groups differ systematically regarding the functional interaction between beliefs about the intergroup situation and identity management strategies. The results of the study indicate too, that ingroup identification differentiates between individual and collective strategies irrespective of the group’s status position.

- Description: In this thesis I discuss three normative claims that I take to be central elements of Charles Taylor’s political thought. The first of these is Taylor’s contention that, in contemporary pluralistic societies, justifying socially prevailing norms by appealing to universally binding moral values is unlikely to promote social solidarity. Because this approach tends to downplay the goods that people realise through membership in particular associations, Taylor believes we must adopt a model of justification that does not prioritise universal over particular goods if we are to further social co-operation. A second claim Taylor defends is that commitment to the liberal value of collective self-rule implies treating patriotically motivated public service as a non-instrumental good. We should not, Taylor argues, regard collective association as nothing more than a means to satisfying private goals. Taylor advances a third claim, that is, he maintains that liberal toleration for diverse ways of life may require a perfectionist state that supports particularistic ways of life when they are threatened by decline. I offer a qualified defence of the first two claims, but suggest that the third is less compelling. I attempt to do this by evaluating Taylor’s claims against the standards of lucid argumentation that he himself lays down. In discussing social and political norms, which he describes as “advocacy” issues, Taylor argues that our normative commitments necessarily rely on an underlying social ontology. More specifically, Taylor argues that the political values we defend are those that enable us to secure the interests we have as the bearers of an identity possessing both individual and collective dimensions. In setting out the conditions that favour integrated and free identity formation we may thereby reach a clearer understanding of the political norms that we wish to endorse. I argue that, while Taylor’s ontological reflections might well incline us to accept his model of justification and his account of patriotic social commitment, they do not of themselves dispose us to accept state perfectionism.

- Description: Despite the profound impacts of HIV and AIDS on all sectors of South African society, governmental responses to the AIDS epidemic have been inundated with contradiction, conflict and contestation. Though governmental leaders have justified not funding HIV treatment programs because they believe that poverty needs to be dealt with first, social spending has been slashed as part of an adherence to a neo-liberal economic model. Though it would seem that the government would seem to have everything to gain by establishing a cooperative relationship with non-governmental actors regarding the epidemic, the relationship between the government and non-governmental actors has instead been described as nothing short of hostile. Though the government enthusiastically backed Virodene, a supposed treatment for AIDS that turned out to be no more than an industrial solvent, other ‘scientifically backed’ AIDS treatments have been treated with caution and skepticism – to the point where the government even refused to provide funding for programs to prevent mother to child transmission of the virus. And perhaps the most perplexing is that although widely respected for his intellect and cool demeanor, former President Mbeki chose to risk his political career on the AIDS issue by shunning away from the mainstream consensus on the biomedical causes of the epidemic and instead surrounded himself and sought advice from AIDS ‘dissidents’ This thesis will seek explanations for these apparent contradictions. Using Bourdieu’s (1986) typology of capitals, it will build on an argument put forward by Helen Schneider (2002): from the South African government’s perspective, the contestation regarding HIV and AIDS policy and implementation is over symbolic capital, or the right to legitimately hold and exercise political power regarding the epidemic. Though this argument helps explain the conflictual relationship between the government and non-governmental actors regarding the AIDS crisis, in order to understand the perplexing contradictions within the governmental policy response, the political context of policy formation must first be taken into consideration.

- Description: Women are subject to a number of societal recommendations about what it means to be an 'ideal' woman. These recommendations take the form of social scripts, constructing an idea of ideal femininity, which women must perform in order to be socially accepted and successful. 'Emphasized femininity', a white, Western, script of femininity is dominant and has been critiqued by feminists, social theorists, and individual women for the limits that it places on women's behaviour. As a result a number of alternative scripts of femininity have arisen. These scripts can provide alternatives to restrictive understandings of female sexuality and beauty - they can serve to challenge 'appropriate' feminine behaviour and hence allow women to live more freely. Raunch femininity is a contemporary alternative that uses sexually explicit public performance, and encourages specific body and dress norms, in an attempt to challenge the norms of emphasized femininity. This thesis looks at raunch femininity, specifically its norms of sexuality and beauty, in the hopes of understanding what the effects of such a script are on women's behaviour. Theoretical understandings and explanations of women's lives are often contradicted by reports that women provide of their lived experiences. For this reason, this thesis investigates the lived experiences of women who self-identify as subscribers to this script in order to assess to what extent superficial expressions of freedom have deeper effects on women's freedom. The tension between theory and empirical reports is evident. However, in many cases, the reports of research participants reveal that the script of raunch femininity, like other scripts of feminine behaviour, has its own limits that women must abide with in order to be accepted. This thesis argues that these limits outweigh the benefits of this script. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This thesis analyses the existing legal framework that applies to franchising in South Africa today. The study begins with an examination of the history and nature of the franchise contract, focusing particularly on the nature of the franchise relationship. This study is undertaken in order to substantiate the argument that franchising is a unique method of doing business. There is a need therefore to recognise that the franchise contract is a special contract in its own right, just like contracts of sale, lease, insurance and suretyship. The study then goes on to examine the problems which are experienced in the sector, as well as the law which must provide solutions to these problems. The research will show that in a modern commercial world the existing legal framework, especially the common law, cannot adequately deal with many of these problems. The complex relationship between franchising and competition law is also explored. A common thread that emerges from franchise disputes is the lack of protection afforded to the interests of franchisees. Franchisees tend to be at the mercy of economically stronger franchisors, hence the belief that there is a need for a stronger regulatory framework. The study then shifts to proposals for reform. In 2000 the Department of Trade and Industry (DTI) established the Franchise Steering Committee in conjunction with the Franchise Association of South Africa (FASA) to review the regulatory environment. This Committee drafted franchise legislation which aimed to bring the regulation of the sector under the control of the DTI. This legislation has not been implemented and the DTI has changed its strategy. Instead of dealing with franchising independently, franchising will fall within the scope of consumer protection legislation. Both the consumer protection legislation and the legislation proposed by the Franchise Steering Committee are thoroughly examined and explained. Shortcomings in the proposals are highlighted and an alternative approach is recommended. It is proposed that franchise-specific legislation should be introduced but that this legislation should establish a system of co-regulation between the government and the franchise sector.

- Description: This research explores issues relating to language policy, and language learning and teaching. It further looks at the relationship that exists between language policy and language learning and teaching. In the research I argue that well-thought out and well-meaning language policies will fail to be implemented meaningfully if there is no clear and unambiguous implementation plan. I also note that the national vision and ideals which are often embodied in the language policy fail to take effect if, again, there is no comprehensive implementation plan. This view is held by many scholars and researchers in the areas of language policy and planning.

- Description: New drugs, particularly antibiotics, are urgently required to combat the increasing problem of antibiotic resistant human pathogens. Due to the scarcity of products available today, the pharmaceutical industry is now under pressure to reassess compounds derived from plants, soil and marine organisms. Pharmaceutical companies are showing renewed interest in marine biotechnology as the oceans represent a rich source of both biological and chemical diversity of novel molecular structures with anti-cancer, anti-inflammatory and antibiotic properties. Formerly unexplored locations, such as deep ocean sediments, show great potential as a source of genetically novel microorganisms producing structurally unique secondary metabolites. In this research, a metabolite producing marine Pseudoalteromonas strain, known as AP5, was initially used to develop methods for the detection, optimisation of production and extraction of bioactive metabolites from other potentially novel marine isolates. Two hundred and seventy six (276) marine isolates from water and sediment samples from the Antarctic Ocean and Marion Island were isolated. Ten visually different isolates were screened for bioactivity against Gram-positive and -negative bacteria, fungi and yeast. Three out of the 10 isolates, WL61 , WL 114 and WL 136, appeared to be novel Streptomyces spp. showing activity against different test organisms. Many of these marine microorganisms are difficult to culture in the laboratory, particularly when they are cultivated continuously in shake flasks as they can stop producing bioactive compounds. The cultivation of marine isolates in bioreactors may be a more beneficial process for the optimisation of metabolite production compared to conventional liquid fermentation techniques whereby the solid-liquid-air interface of membrane bioreactors can imitate the natural environment of microbes. The membrane bioreactor system is a stable growth environment with low shear that supports steady-state biofilm growth consisting of a high cell density due to a high mass transfer of nutrients and oxygen to the cells. This approach was employed and isolates WL61, WL114 and WL136 were immobilised onto ceramic membranes using Quorus single fibre bioreactors (SFR). The SFRs were used to establish the most suitable growth medium for continuous secondary metabolite production. The best growth conditions were applied to the Quorus multifibre bioreactor (MFR) for scale up of biologically active metabolites, highlighting the potential of bioreactor technology for use in bioprospecting for isolating and screening novel and known organisms for new and interesting natural products. Furthermore, the Quorus MFR was shown to be suitable for the production of high yields of antimicrobial metabolites and is an efficient new fermentation production system. Purification by HPLC fractionation was used to characterise four major compounds from isolate WL 114 extracts. NMR structure elucidation identified one of the two primary compounds as Bisphenol A. The complete chemical structure for the second potent bioactive compound could not be determined due to the low concentration and volume of material. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This study focused on the implementation of ICTs in secondary schools in Lesotho. The main question addressed was: What are the enabling and constraining factors in the implementation of ICTs in schools? The work was undertaken in recognition of the fact that schools in the country were autonomously acquiring computers and using a variety of curricula without much coordination and policies from the government. There were factors encouraging schools to delve into this educational change: and challenges were already evident. This required further investigation. The research approach commenced with a critical review of the literature. Literature was drawn from developed and developing countries in order to understand the process of ICT implementation from a variety of contexts. The enquiry about the implementation process in all the countries focused on the rationale behind the use of ICTs in schools. ICT policies guiding implementation, principal leadership, teacher professional development and ICT resources. The literature review was followed by case studies of three secondary schools in Mafeteng district in Lesotho. Using both qualitative and quantitative methods of research, the study sought to determine from key people in three case study schools their overall understanding of how the process of implementation was carried out and what they perceived as enablers and constraints. The findings revealed that planning, access arrangements, training, support and to a lesser extent resources played a role in either impeding or encouraging the key ICT implementers at school and classroom level. Additionally, the key role of the principal and the MoE were highlighted in the study.

- Description: Can mining industries and mining based localities promote Local Economic Development (LED)? This case study, on the mining town of Oranjemund, seeks to examine the economic diversification prospects of the town. Stakeholder views are considered and their aspirations determined, through an interview process. Relevant theories on economic development, growth and sustainability are outline. Lessons are drawn from local and international empirical studies on mining towns. The roles and contributions stakeholders and institutions could realize that could lead to local economic diversification and LED are defined. The opportunities and threats that could affect the town’s LED process are identified. This paper concludes that it is imperative that sound relationships be developed amongst key stakeholders. It further, recommends that a strategic LED plan be designed for Oranjemund and that national government, through the regional and local authority, lead the process.

- Description: The international dilemma of child soldiers is a humanitarian concern throughout the world. The Coalition to Stop the Use of Child Soldiers (CSUCS) began in 1998 and is currently the leading collaborative movement to address the issue. However, because of its emphasis on a universal 'Straight 18' approach and support of the Optional Protocol of the Convention on the Rights of a Child (CRC), the CSUCS ignores contextual realities that affect the implementation ofthe international legislation and the development of norms concerning child soldiers. This research project will examine the current international nongovernmental organization (INGO) response to child soldiers- focusing on the CSCUS - and formulate suggestions for potential avenues to further INGO involvement with policies and projects. The argument is based on a neoliberal institutionalist platform that argues in favour ofiNGOs' ability to successfully influence actions taken by state actors to address human right issues. Highlighting the successful INGO influence on states during the International Campaign to Ban Landmines, I will present this example as a potential model for the Coalition to Stop the Use of Child Soldiers, and explore the feasibility of this model whilst making suggestions for more effective involvement of INGOs with regard to the issue of child soldiers.
