- Description: Substitute care is a temporary or permanent placement of children under the supervision of an adult person due to the absence of their biological parents. The escalating divorce rate, increase in extramarital births, high incidence of family violence, the growing number of children orphaned by HIV/AIDS, and the increasing career-orientatedness of parents have led to the development of diverse family structures. Grandparents and other family members are increasingly becoming the primary caretakers for children. Whilst it is generally assumed by society that children’s well-being is better served when they are raised by their biological parents, the purpose of this study is to: • explore what influence substitute care has on learners’ motivation; • formulate guidelines and recommendations for educators to improve the current levels of motivation of learners in substitute care. The literature related to substitute care and motivation were reviewed, with the aim of providing a firm theoretical basis for the study. Concepts related to motivation discussed, included types of and sources of motivation. Concepts related to the second focus of this study included forms of substitute care. Motivational theories related to this study were briefly discussed, namely: the Attribution Theory, the Drive Theory, Goal Theory, and the Self-worth and Selfefficacy Theories. Factors that have a motivational influence on learners, such as acceptance versus rejection, praise versus criticism, success versus failure and positive self-concept versus negative self-concept, were also discussed. A link was then drawn between motivation and substitute care. ii The research design chosen for this study can be described as qualitative, interpretive and constructive in nature. The research study was conducted in two phases: Phase One provided an investigation of the research problem by means of the following open-ended question: What is the influence or impact of your status as a child in substitute care on your motivation? Data were collected by means of eleven unstructured, in-depth personal interviews. Purposeful sampling was undertaken, which included high school learners all in substitute care. Data were analysed, as proposed by the eight steps of Tesch. Discussions between the observer, moderator and an independent re-coder took place to determine the final results of the research through a consensus principle. Key and related concepts were clustered together to formulate themes, categories and sub-categories. The following three themes emerged, based on the results of the data analysis. I. Problems in the close family circle have profound effects on learner motivation. II. Certain motivating forces help learners in substitute care to cope. III. Substitute care does influence learner motivation. Phase Two offered recommendations, derived from the findings of Phase One, to empower teachers in effectively supporting and motivating learners in substitute care. The conclusion was reached that substitute care does have an influence on the motivation of learners. This motivation can either be positive, which means encouraging learners towards their goal, or negative, which implies that it moves learners away from their goal.

- Description: This small scale exploratory research project investigated the grounding of rational number concepts in informal, everyday life situations. A qualitative approach was taken to allow for the identification and then in depth investigation, of issues of importance for such a grounding of rational number understanding. The methodology followed could be seen as a combination of grounded theory and developmental research. And the data was generated through in-depth and clinical interviews structured around a number of grounded tasks related to rational numbers. The research comprised three cycles of interviews that were transcribed and then analysed in detail, interspersed with periods of reading and reflection. The pilot cycle involved a single grade three teacher, the second cycle involved 2 grade three teachers and the third cycle involved 2 grade three children. The research identified a number of different perspectives that were all important for the development of a fundamental intuitive understanding that could be considered personally meaningful to the individual concerned and relevant to the development of rational number concepts. Firstly in order to motivate and engage the child on a personal level the grounding situation needed to be seen as personally significant by the child. Secondly, coordinating operations provided a means of developing a fundamental intuitive understanding, through coordination with affording structures of the situation that are relevant to rational numbers. Finally, goal directed actions that are deliberately structured to achieve explicit goals in a situation are important for the development of more explicit concepts and skills fundamental for rational number understanding. Different explicit structures give rise to different interpretations of rational numbers in grounding situations. In addition to these perspectives, it became evident that building and learning representations was important for developing a more particularly mathematical understanding, based on the fundamental understanding derived from the child's grounded experience. The conclusion drawn in this research as a result of this complexity, is that to achieve a comprehensive and meaningful grounding, children's learning of rational numbers will not follow a simple linear trajectory. Rather this process forms a web of learning, threading coordinating operations for intuitive development, interpretations for explicit grounding and representations to develop more formal mathematical conceptions.

- Description: The crime of in-transit robbery is a sub-specie of the common law crime of robbery, which in essence is a crime of theft with violence. Robbery had evolved from begging, where beggars would harass their victims for money or items of value and then elevating their begging efforts to threats of violence, and in certain instances the usage of physical violence to solicit alms. As soon as road transport became prominent in society, the incidence of in-transit robbery increased where violence was used to overcome any form of resistance from the victim. During sea-faring transportation, piracy occurred using similar methods of violence to obtain goods from victims. In-transit robbery has undergone many changes in terms of modus operandi. From the early days of violent begging during the Roman Empire it has now become a greed driven, carefully planned crime, which is executed with military precision with high technology weapons of war. Robbery has advanced in judicial terms from a non-codified crime to a specific defined crime which carries prescribed minimum sentencing as punishment. , Abstract

- Description: Immovable asset management is the key element in enabling better service delivery by the national government. An improvement in the management of government’s immovable assets is required in South Africa to ensure that assets are optimally utilised for service delivery. The entire research attests to the importance of excellent management of government immovable assets throughout its life cycle within a framework of cost effectiveness, efficiency and reduced risk. The study discusses three technical challenges which comprise the incompleteness of the asset register, immovable asset life cycle management, a lack of implementation of the immovable asset management plan, the asset performance measures and standards for the immovable assets. The National Department of Public Works was targeted as a potential candidate to participate in this research. Primary data was collected through questionnaires and interviews to reveal the strengths and weaknesses and to develop the current theories and models. Secondary data was collected from books, journals, internet and conference papers. The asset management branch in the department was formed recently. The results of the research indicated that the asset management frameworks and the immovable asset management plans are not implemented as designed and there is no integration between the asset’s life cycle processes. The corrosion of information in the asset register was because of a lack of asset-computerized systems, competent personnel and adequate skills. In conclusion, immovable assets should be managed through integrated life cycle processes, policies and procedural documents should be developed and planning is important to the management of immovable assets. The asset register should work as a basic system for the management of immovable assets.

- Description: Cyclic dipeptides are widely used as models for larger peptides because of their simplicity and limited conformational freedom. Some cyclic dipeptides have been shown to produce antiviral, antibiotic and anti-tumour activity (Milne et al., 1998). In this study the cyclic dipeptides, cyclo(Ser-Ser) and cyclo(Ser-Tyr), were synthesised from their corresponding linear precursors using a modified phenolinduced cyclisation procedure. The phenol-induced cyclisation procedure resulted in good yields and purity of the cyclic dipeptides. Quantitative analysis and evaluation of the physicochemical properties of the cyclic dipeptides was achieved by using high-performance liquid chromatography, scanning electron microscopy, thermal analysis and X-ray powder diffraction. The structures of the synthesised cyclic dipeptides were elucidated using infrared spectroscopy, mass spectrometry, nuclear magnetic resonance spectroscopy and molecular modelling. The study aimed to determine the biological activity of cyclo(Ser-Ser) and cyclo(Ser-Tyr) with respect to their anticancer, antimicrobial, haematological and cardiac effects. Anticancer studies revealed that cyclo(Ser-Ser) and cyclo(Ser- Tyr) inhibited the growth of HeLa (cervical cancer), HT-29 (colon cancer) and MCF (breast cancer) cancer cell lines. Both cyclic dipeptides also inhibited the growth of certain selected Gram-positive, Gram-negative and fungal microorganisms in the antimicrobial study. Although the inhibition of growth in the anticancer and antimicrobial studies was statistically significant, the clinical relevance is questionable, since the inhibition produced by both cyclic dipeptides was very limited compared to other pre-existing anticancer and antimicrobial agents. Cyclo(Ser-Tyr) exhibited significant activity in the haematological studies, where it increased the rate of calcium induced-coagulation, and decreased the rate of streptokinase-induced fibrinolysis. Both cyclic dipeptides, however, failed to produce any significant effects on thrombin-substrate binding and ADPinduced platelet aggregation. Cardiac studies revealed that cyclo(Ser-Ser) and especially cyclo(Ser-Tyr) reduced the heart rate, coronary flow rate and ventricular pressure of isolated rat hearts.

- Description: This thesis presents a history of the landscape of Nqabara, an administrative area in a rural and coastal area of the Eastern Cape Province, South Africa. In the process of investigating landscape history, the inquiry engages with a range of data sources from diverging discursive contexts, including data from ethnographic fieldwork, from the consultation of archival documents and historical reports as well as from comparative historic and ethnographic research, necessitating a critical consideration of the epistemological contexts of data production and the dialogue between researcher and data. Furthermore, in its aim to move beyond historical description towards explanation, the study interrogates the dualist ontological conceptualisations of nature and culture, society and ecology, object and meaning upon which are built three dominant conceptual frameworks concerned with human-environment relationships: social-ecological systems theory, transdisciplinary landscape studies and political ecology. Drawing primarily upon the works of James Gibson, Anthony Giddens and Tim Ingold, an ontological foundation is developed to guide the enquiry and move towards an alternative understanding of the relationship of people’s livelihoods with respect to the landscape in which it is lived, which I call here the praxisembodiment perspective. This ontology takes the situated patterns of action of a situated agent-in-its-environment as its point of departure and proceeds to develop a framework explaining how relations among the patterns of action of different agents-in-their-environment, emerge in structures that simultaneously enable and constrain future action. The foundation is thereby provided for a monist understanding of how landscape and social structure emerge simultaneously from the complex intersection of patterns of actions and interactions of agents in their environment. This framework calls for an understanding of time, space and scale, not as independent variables influencing process and action, but as emergent properties arising from the patterns of actions of situated agents. Finally the alternative ontology is applied to the history of landscape and livelihoods of people of Nqabara. It is concluded that an appropriate understanding and explanation of the critical transformations in the landscape as well as in social institutions, should be sought through analysis of the complex ways in which patterns of action of multiple spatial and temporal rhythms and between multiple agents in an environment, intersect and resonate.

- Description: Despite the current widespread implementation of inclusive education into the South African educational system, it appears that little, if any, studies have been undertaken as to whether South African educators are adequately equipped to manage the changes that will be required with the implementation of this new approach to education. More specifically, whether our educators would be more aptly prepared for the many adaptations should they be in possession of a remedial qualification. This study is aimed at providing a detailed account of the implications of introducing inclusive education into the South African school system, with particular focus being placed on learners who present with barriers to learning as well as the essential curriculum, classroom and teaching adjustments required in order for these learners to reach their full potential within a mainstream classroom environment. The sample for this study firstly comprised of educators’ perceptions regarding their capabilities in coping with the demands of inclusive education. The viewpoints of 122 educators, within the Nelson Mandela Metropolitan area of the Eastern Cape, were recorded through the completion of individual questionnaires and interviews. Secondly, the files of 111 learners, from a remedial practice, who presented with barriers to learning were analysed to determine the effectiveness of appropriate remedial intervention in overcoming the respective barriers. The major findings of the present study were as follows: Many classroom modifications, changes in teaching styles and curriculum adaptations would have to be implemented to adjust to the demands of inclusive education; Educators would have to be trained regarding the different categories of learners with barriers to learning and their special educational needs; The majority of Eastern Cape educators do not feel suitably qualified to cope with the demands of inclusive education; Educators in positions of authority (principals, deputy principals and heads of department) indicated their inadequacies regarding coping and assisting parents and fellow educators with the demands of inclusive education; A large percentage of the responding educators indicated that they would be better suited to cope with the demands of inclusive education with a remedial qualification and were prepared to register at a tertiary institution to obtain such a qualification depending on certain incentives offered by the Education Department. In view of the findings of this study, recommendations have been made to enhance the current qualification levels of educators, to specifically include a remedial qualification, of which guidelines have been provided. This approach should vastly assist educators in coping with the demands of inclusive education and will ensure that they are suitably empowered to meet the needs of learners with barriers, who have been thrust into this system. Guidelines are also offered for a proposed remedial course that could be offered to education students as well as to those educators who are presently in the employ of the Education Department.

- Description: Stormwater attenuation policy has, over recent years, become a highly contentious issue for the property development community. Increased urbanisation, locally and internationally, has forced municipal authorities to reconsider the role of stormwater management in this evolving urban landscape. It is within this context that the legislative support and municipal policy for stormwater management in the City of Johannesburg has been explored, particularly in terms of the economic impact on property developers. The research aimed to explore the relationship between stormwater attenuation policy and the economic impact thereof on private property developers. Consideration was given to the cost, risk and time factors of legislative and policy requirements within the development process. Further consideration was given to the physical environment that has brought about current pressures. Based upon research of international issues highlighted in countries with well developed attenuation policy, a questionnaire was constructed to evaluate the response of local private property developers to selected issues as key sub-problems. The responses were tested against the developed set of hypotheses. The research indicated that developers had a generally poor level of knowledge with regard to the stormwater management policy of the City of Johannesburg, as well as the supporting legislative requirements of provincial and national policy documents. The results of the survey also indicated that developers were strongly opposed to the loss of developable area, but indicated a limited financial impact of the current stormwater attenuation policy. The risk inherent in incorporating an attenuation facility within a development was identified as being low with little perceived impact. Developers further indicated that the inclusion of attenuation facilities was seen as a significant contributing factor in the delay, approval and acceptance of new developments in which attenuation facilities were required, while maintenance costs were indicated to be of a low level of importance. Recommendations in response to the research findings included the establishment of detailed policy documentation and support for effective distribution channels in conjunction with industry and public focused information campaigns, improved municipal capacity and a greater level of technical support. A need for additional stormwater research and an increase in the capture of relevant data for GIS purposes was identified.

- Description: This thesis examines the political implications of the integrated development planning process embarked upon by South African municipalities in the period 1998-2004. Through the use of case study methodology that focuses on the Eastern Cape municipalities of Buffalo City and Ngqushwa, the conventions of municipal planning are examined. This inquiry into municipal planning draws upon official government documents and reports and publications from the nongovernment sector. The thesis is particularly focused on the claims made in policy documents and related secondary sources and compares these to more critical reports and publication as well as the author's personal experience of the integrated development planning process. Of key interest is the possibility that planning serves political interests and the material needs of an emerging municipal elite and that this is seldom acknowledged in official planning documentation or government sanctioned publications on the topic. The primary findings of the thesis are as follows: • That the 'reason' of expert policy formulations that accompanied integrated development planning has weakened political economy as a prism of understanding and separated itself from the institutional reality of municipal government • That the dominant critique of planning and other post-apartheid municipal policy is concerned with the triumph of neoliberalism but this critique, while valid, does not fully explain successive policy failures especially in the setting of Eastern Cape local government • That function of policy and its relationship to both the state and civil society is usually understood only in the most obvious sense and not as an instrument for wielding political power • That planning still derives much of its influence from its claim to technical rationality and that this underpinned the 'authority' of the integrated development planning project in South Africa and reinforced its power to make communities governable.

- Description: Rural schools generally find it hard to function effectively for a variety of reasons, and managing and leading these schools brings additional challenges. This study explored the role of the principal in an academically successful rural school in Namibia. It drew on leadership theory and findings from related studies to make sense of this particular case of leadership against the odds. Using the interpretive orientation, the research explored selected organisation members’ perceptions of the principal’s leadership through semi-structured interviews. The study found that the actions and attitudes of the leader had a significant influence on the school’s performance. The manner in which the principal conducted himself, the shared vision he encouraged and his insistence on associating with all stakeholders involved in education, were instrumental in the organization’s positive achievements. The principal was shown as committed and a leader with good interpersonal working relationships. The study also revealed that this principal was both a person- and taskoriented leader, and closely resembled the ideals of transformational leadership. This study further found that, through the principal’s instructional leadership, teaching and learning are seen as the core of the school’s activities. Finally, the principal’s leadership role opens the school to the community and results in strong and mutually beneficial relationships between the school and its community.

- Description: Infertility is a complex condition associated with the inability to conceive a child, frequently manifesting itself as a result of various biological factors. A literature review indicated that being on Artificial Reproductive Technology (ART) treatment significantly increases the stress in an individual. While some research has been done on coping processes, and stress and depression levels in individuals on infertility treatment, very little literature is available regarding the coping resources and subjective well-being of individuals on infertility treatment. This psychofortigenic study aimed to explore and describe the coping resources, sense of coherence, satisfaction with life and life happiness of individuals undergoing infertility treatment. Furthermore, this study aimed to compare the coping resources, sense of coherence, satisfaction with life and happiness of males and females undergoing infertility treatment at a privately managed unit. It is imperative to view the results of this study from a gender-based perception as a previous study by Ferreira (2005) indicated significant differences in how males and females perceived infertility treatment. The sample in this study consisted of 62 voluntary participants from a privately managed health care unit in the Nelson Mandela Metropole. Participants were given a package of questionnaires to complete under the supervision of the researcher and research coordinator of the participating health care unit. The assessment consisted of a biographical questionnaire and four standardised paper and pencil measures. The participants’ coping resources were explored using Hammer and Marting’s (1988) Coping Resource Inventory (CRI), while Antonovsky’s (1987) Orientation to Life Scale was used to measure their sense of coherence (SOC-29). Overall satisfaction with life was assessed using Diener, Emmons, Larson and Griffin’s (1985) Satisfaction with Life Scale (SWLS), while Kamman and Flett’s (1993) Affectometer-2 (AFM-2) was utilized to measure the respondents’ subjective happiness. A quantitative, exploratory descriptive research design was employed in this study and the participants were chosen by means of a non-probability purposive sampling procedure. Data was analysed using descriptive statistics and independent t-testing. Further investigations were made through Chi square tests which enabled the researcher to draw inferences about differences based on cross tabulations. The reliability coefficient was obtained by calculating Cronbach’s coefficient alpha, which measured the internal consistency of the four standardized measures utilised in the present study. The results of the study revealed that participants generally experienced average levels of coping and subjective well-being as measured by the four assessment tools utilised during this study. On comparing the results of the male group and the female group of the particular sample it was found that although both groups obtained relatively average mean scores in general, the men scored slightly higher on the Coping Resources Inventory, Sense of Coherence and Affectometer-2, while the females scored slightly higher than the males on the Satisfaction with Life Scale.

- Description: The years spent studying towards a degree represent many challenges to the learner1. These pressures increase once that learner moves into the post-graduate level of professional study. Faced with the pressure of having to perform suitably in order to remain on the programme, the learner finds himself or herself under conditions which may present as stress or illness, depending upon the availability of coping resources and strategies. This study adopted a psychofortigenic2 approach and explored and described the coping (i.e., coping resources and sense of coherence) and subjective well-being (i.e., satisfaction with life, happiness and general psychiatric health) of post-graduate learners in the following six departments of the Faculty of Health Sciences at the Nelson Mandela Metropolitan University (NMMU): Psychology; Human Movement Science and Sport Management; Environmental Health and Social Development Professions (incorporating MA Health and Welfare Management); Pharmacy; Nursing Science; Biomedical Technology and Radiography. An exploratory descriptive research design was used and the participants were selected by means of non-probability, convenience sampling. The sample consisted of 60 male and female masters and doctoral post-graduate learners in the Faculty of Health Sciences. Biographical data was gathered by means of the administration of a questionnaire. Hammer and Marting’s (1988) Coping Resources Inventory was used to measure the students’ available coping resources. Furthermore, Antonovsky’s (1987) Orientation to Life Scale was used to measure the construct of Sense of Coherence. The Satisfaction with Life Scale by Diener, Emmons, Larson and Griffin (1985) was used to assess the respondents’ overall satisfaction with life. Kamman and Flett’s (1983) Affectometer-2 was used to measure participants’ subjective global happiness. The General Health Questionnaire of Goldberg and Williams (1988) was used to measure the psychiatric morbidity or general psychiatric health of the participants. The data was analyzed using both descriptive statistics and cluster analysis. A Hotellings T² was computed with subsequent t-tests to draw inferences about differences in the means of established groups across the five measures. The results indicated that the participants were generally coping and experiencing subjective well-being. The results indicated two clusters to significantly differ from one another across the five measures. The first cluster could be characterized as high in psychofortology and presented with better coping and subjective well-being. The second cluster could be characterized as low in psychofortology and presented with poorer coping and subjective well-being.

- Description: After careful review of all the relevant literature pertaining to motivation, performance management and compensation in the form of incentives, this thesis focuses primarily on determining whether a statistically significant relationship exists between individual needs and the choice of an incentive scheme option. The secondary aims of the research are to determine whether: A relationship exists between the job grade of an individual and the choice of an incentive scheme. A particular incentive scheme option is preferred by the employees in The South African Breweries (SAB). A particular preference exists, and if so, to make recommendations to SAB for consideration as alternatives to their existing incentive scheme options. After collation of the survey data from the respondents in the sample, the analysis and discussion of the results determined that no significant relationship exists between individual needs and the choice of an incentive scheme option. It was, however, determined that a significant relationship exists between the grade of the employees in SAB and their choice of an incentive scheme. 81% of all respondents indicated a desire for shares as an option in their Short Term Incentives (STI) which indicates a desire for shares in some form or another and may well indicate a level of confidence and commitment by the employees to the organisation. Although the research hypothesis was not proven, significant insights into remuneration within SAB was obtained, which has resulted in recommendations being made for further research into the option of shares in some form or another in the organisation. A further recommendation for SAB is to consider some form of share options for all employees in the organisation. As many other organisations that are performing at remarkable levels attest this performance to share ownership and the behaviour that emanates from it, it would be in the interests of SAB to further investigate the issue as it may improve performance, ownership and retention within the company.

- Description: This research investigates the relationship between leadership styles and different types of organisational commitment in Eskom Eastern Region. The literature provided discusses the leadership and organisational commitment. Information was gathered, using two instruments, from a sample of 86 leaders and 334 raters. The Multifactor Leadership Questionnaire, which was formulated from Bass and Avolio’s (1997) Full Range Leadership Development Theory, was used to determine leadership style within the organisation. Employee commitment was captured using Bagraim’s (2004) Organisational Commitment, a South African adaptation of Meyer and Allen’s (1997) Three-Component Model of employee commitment. Leadership was identified as the independent variable and organisational commitment as the dependent variable. Data obtained from each of the research instruments was then statistically analysed. Two-tailed correlation analysis showed that although the relationship is not strong, there is a positive relationship between the transformational leadership behaviours and commitment (affective commitment, continuance commitment and normative commitment). The correlation analysis also indicates a weak, but significant, positive relationship between transactional leadership behaviours and continuance commitment. However, no statistically significant correlation was found between transactional leadership behaviours and affective commitment as well as between transactional leadership behaviours and normative commitment. The correlation results showed a weak, but significant, negative correlation between laissez-faire leadership behaviours and affective commitment. There was no statistically significant correlation between laissez-faire leadership behaviours and continuance commitment as well as between laissez-faire leadership behaviours and normative commitment. Overall findings from this study suggest that transformational and transactional leadership behaviours do play important roles in determining levels of affective commitment, continuance commitment and normative commitment. These findings also reveal that the laissez-faire leadership behaviour had a negative relationship with affective commitment. This research therefore adds a new dimension to the body of literature that will help researchers’ efforts to understand the relationship between leadership style and organisational commitment. As this research takes place in the South African context, it contributes to the bank of findings relating to the development of organisational commitment.

- Description: This study analysed the representation of South African women politicians in the Sunday Times’ election news during the 2004 Presidential and general elections, by drawing on perspectives from cultural studies, the constructionist approach to representation and the sociology of news production. Using content analysis and critical discourse analysis, the study found that very few women politicians were used as news actors/sources in the Sunday Times, and that when women politicians were figured, the paper tended to present them in ways that serve to sustain women’s subordinate status in society. Using content analysis, the study analysed 106 news items published between January 1, 2004 and April 30, 2004, and found that of all the 588 identifiable news actors/sources counted, 135 were women and 453 were men. Of these, only 7.67% (or 26) were women politicians and 92.33% (or 313) were men politicians. On average however, the amount of words allocated to a woman politician was more than that allocated to a man politician. The discourse analysis also revealed how the Sunday Times managed to reproduce textually the hegemonic power relations between women and men, by constructing different subject positions for women politicians and men politicians, which generally tended to be negative and positive respectively. In the representation of women politicians, the study revealed patterns that tended to ascribe them negative personality traits, accentuate their passivity and dependency on men, and construct them as incompetent political leaders. This study’s conclusions pose a challenge to the role of the national newspaper in the transformation of gender relations and the promotion of equal access to political and decision-making positions, and to the news media. News discourse, as a social practice, both determines and is determined by the social structure in which it is produced. By systematically reproducing subordinate subject positions for women in the news, the Sunday Times helps to further women’s subordinate status in society. Particularly, as part of the broader social cultural context that is embedded in patriarchal and gender ideologies, the Sunday Times does not merely reflect but actively and effectively constructs the reality it claims to be representing.

- Description: This thesis is an investigation into the socio-economic constraints that influence the decisions of tuberculosis sufferers in the health seeking process and therapeutic management of tuberculosis in Grahamstown, the Eastern Cape. It is shown that structural violence influences experiences and perceptions of tuberculosis at all levels. Management of tuberculosis in the formal health sector is explored at local levels and related to national and global strategies of health care. The role of health workers, and particularly voluntary health workers, is explored and it is shown that they work within a context of growing burden of sickness and co-infections and a lack of government commitment to deal with increasing TB and HIV incidences. Kleinman’s notion of explanatory models is explored and it is evident that although knowledge of the aetiology of tuberculosis is well-known to patients and general members of the communities, they are nevertheless victims of increased stigmatisation and marginalisation as a result of illness. The importance of social support in curing tuberculosis is explored using Janzen’s concept of therapy managing groups. Social capital is a fundamental component in adhering to biomedical therapy, but is commonly weak among the structurally poor. The availability of temporary social grants for people living with TB influences health seeking behaviour. In a context of structural poverty the sick are faced with what Nattrass terms “perverse incentives”, having to choose between the right to health and the right to social security, both guaranteed in the South African Constitution, for him/herself and dependants. Although adherence to biomedical therapy is essential in curing tuberculosis, it is shown throughout this thesis that ignoring wider structural causes of disease limits the patient’s ability to get well. The ethnography shows that the right to health is a social and economic right which is not the reality for most South Africans.

- Description: Under the 1956 Labour relations Act, parties who were dissatisfied with decisions of the then Industrial Court, could appeal to the old Labour Appeal Court, and then if still further unhappiness persists, to the former Appellate Division. Such appeals entailed placing before the court the complete record of the Industrial Court, and requesting it to decide if on the evidence, it would have come to the same conclusion. Sometimes the courts of appeal decide that they would, sometimes that they would not. When planning the new Labour Relations Act 66 of 1995, the Cheadle Commission decided that this process was too slow, too technical, too cumbersome and too expansive. So it recommended that, at least in the case of the most common disputes, the issues should be decided quickly, informally and finally by arbitration. Unless the parties agree to private arbitration under the Arbitration Act, 42 of 1956, the Commission for Conciliation, Mediation & Arbitration (CCMA) would supply the arbitrators, who would exercise their powers, not under agreed terms of reference, but under the LRA itself. Like private arbitrators, those of the CCMA are also meant to dispose of matters with a minimum of legal formalities (see section 138(1) of the LRA). But the drafters of the LRA did not mean to insulate arbitration awards entirely from the watchful eye of the Labour Court. They therefore specifically provided for review of CCMA arbitrations awards in section 145, but they also gave general powers of review in section 158(1)(g) respectively of the LRA. As if the jurisdictional puzzle created by the LRA was not complex enough, the legislature added the Promotion of Justice Act 3 of 2000. It is an attempt to give expression to the constitutional right of fair labour practices and the constitutional standard of lawfulness and rationality. If section 145 limits the grounds on which commissioners’ actions can be reviewed, or if that section cannot be interpreted to reconcile it with the PAJA, it may well be that section 145 cannot pass constitutional muster - unless that section constitutes a limitation compliant with section 36 of the Constitution. That would be for the Constitutional court to decide.

- Description: The existence of an occupational health and safety policy is believed to be evidence of management accepting their occupational health and safety role in terms of the Occupational Health and Safety Act. It is accepted that this results in management ensuring the provision of a safe workplace. Despite the emphasis in legislation (the Occupational Health and Safety Act) on the need for management to implement comprehensive occupational health and safety policies, there is a lack of research on the implementation and efficacy of occupational health and safety policies in the workplace. This study investigates the efficacy with which management carries out their occupational health and safety duties and responsibilities when implementing the provisions of an occupational health and safety policy in the workplace. A number of factors are essential to the efficient performance of management in this regard. These factors include managerial commitment, practices and strategies; communication practices and structures; training initiatives and information; the extent of employee and trade union involvement; and the infrastructure of the organisation. This research study is primarily qualitative in nature. Semi-structured interviews were the primary tool used by the researcher to collect the data. The case-study research method was employed to assist the researcher in collecting the data. The participants involved in the research were selected using the principles of strategic informant sampling and expert choice sampling. The participants consisted of a sample of management, employees and shop stewards. The research findings indicate that firstly, the presence of occupational health and safety policies, practices, strategies and systems in the workplace do not automatically result in reduced hazards, accidents or deaths in the workplace. Secondly, the participation schemes and the communication practices put in place by management are weak. The reason for their weakness is their ineffective implementation by management and use by employees and the trade union. Thirdly, management has a definite impact on the involvement, attitudes and actions of the employees and the trade union in occupational health and safety issues. Fourthly, there is an unequal partnership between management and employees as a result of the educational differences regarding occupational health and safety between them. The outcome is that management and employees are faced with numerous challenges in relation to occupational health and safety. Contributing to this challenge is a lack of sufficient resources allocated to training, resulting ultimately in the ineffective monitoring of occupational health and safety in the workplace. The existence of occupational health and safety structures and systems does not provide the essential evidence to suggest that their mere presence makes a difference to the workplace safety level. However, through more co-operation and participation by all the parties, these structures and systems have the potential to be effective. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

The role of aardvarks (Orycteropus afer) as ecosystem engineers in arid and semi-arid landscapes of South Africa

- Description: Arid and semi arid environments are characterised by extreme fluctuations in temperature and low rainfall which present significant challenges to the animals inhabiting these areas. Mammals, such as aardvarks (Orycteropus afer, Pallas 1766), excavate burrows in order to avoid predators and climatic extremes and are termed “ecosystem engineers” as they physically modify their environment and in doing so create new habitats and alter the availability of resources to other species. In this study I assessed the microhabitat conditions (maximum and minimum temperature, relative humidity and seed abundance) of aardvark burrows in relation to paired control sites. In addition, I evaluated the use of aardvark burrows by other vertebrate and invertebrate species and investigated the impact of aardvark burrow mounds on landscape scale floristic diversity. Maximum temperatures were significantly lower (p < 0.05) and minimum temperatures and midday humidity were significantly higher (p < 0.05) inside the burrows at the three study sites, Kwandwe Private Game Reserve (Kwandwe), Mountain Zebra National Park (MZNP) and Tswalu Kalahari Reserve (Tswalu). There were no significant differences between the concentration of seeds, the average numbers of unique individual small mammals, trap success or small mammal species richness recorded inside the burrows compared to outside (p > 0.05). At all three sites, small mammal species diversity was higher in the burrows but this result was also not significant (p > 0.05 for all). Trap success and the number of individuals captured was higher at Tswalu than the other two sites (p < 0.05 for both). The different methods used in this study revealed a total of 25 mammal, seven bird, one amphibian and six reptile species utilising aardvark burrows. There were significant differences in insect community assemblages between the burrows and open control areas at Kwandwe and Tswalu (p < 0.05 for both) but not at MZNP (p > 0.05). The parasitic guild was more prominent inside the burrows than outside but their abundance was not as high as anticipated, possibly due to the placement of traps closer to the burrow entrances than the sleeping chambers. The complex structure of the burrows prevented the placement of traps in close proximity to the sleeping chambers. As expected, the amount of bare earth was significantly higher on active and recently abandoned burrow mounds compared to the old burrow mounds and reference plots at all three sites (p < 0.05 for all), with the exception of the active burrows at Tswalu. Overall, the different plot types were characterised by significantly different plant communities during all the seasons at MZNP, during three of the seasons at Kwandwe and only during winter at Tswalu. The total species richness recorded on the reference plots was higher than on the burrow mounds at all three sites. However, species diversity on the reference plots was not significantly higher than the burrows at any of the sites (p > 0.05 for all sites). Although the results were not significant, the overall species diversity at a site level was greater than the reference patches at Kwandwe and Tswalu (p > 0.05 for both). Aardvarks fulfil the criteria of a significant ecosystem engineer and their presence in arid and semi-arid environments is likely to be critical to the survival of other individual organisms and species, particularly when alternative burrowing animals are either absent or restricted in their activities. Thus, aardvark populations should be considered a conservation priority in arid and semi-arid ecosystems.

- Description: Fundamental processes underpinning the biotransformation of coal by fungal biocatalysts have been intensively investigated, however, limited large-scale industrial applications using such systems have been reported. The un-anticipated sporadic growth of Cynodon dactylon on the surface of un-rehabilitated discard coal dumps has been noted and this was found to be coupled with the breakdown of coal into a humic soil-like material in the top 1.5 metres of the dumps. Extensive fungal growth was observed to be associated with the Cynodon dactylon root system and examination of plant roots indicated the presence of mycorrhizal fungi. Analysis of the Cynodon dactylon plant roots around which coal biotransformation was occurring confirmed the presence of arbuscular mycorrhizal colonisation with the species Glomus clarum, Paraglomus occultum, Gigaspora gigantea and Glomus mosseae identified to be associated with the plants. Further molecular characterisation of non-mycorrhizal rhizospheric fungi showed the presence of fungal species with coal-degrading capabilities that most likely played a role in the coal biotransformation observed. The discard coal dump environment was simulated in pot and column studies and coal biotransformation was reproduced, with this process enhanced by the addition of mycorrhizal and non-mycorrhizal rhizospheric fungal inocula to the environment. Mycorrhizal and non-mycorrhizal species in the inoculum were re-isolated from the simulated environment fulfilling a number of Koch’s postulates and indicating a causal role in the biotransformation of coal. An inversion of conventional mycorrhizal colonisation was demonstrated in this system with reduction in extraradicular presence and an increase in intracellular colonisation compared to soil controls. A descriptive model was formulated suggesting a two-part fungal system involving organic carbon and nutrient exchange between the plant, mycorrhizal fungi and non-mycorrhizal coal-degrading rhizospheric fungi ultimately resulting in the biotransformation of coal. The biotransformation observed was comparable to reports of “rock-eating fungi”. Results suggest that the biological degradation of coal in situ with the production of a soil-like substrate could provide a feasible method of discard coal dump rehabilitation as well as provide a humic-rich substrate that can be utilised in further industrial applications.
