  • Description: At the University of Port Elizabeth (UPE), the End User Computing course (EUC) acts as a service course for many departments. This implies that many students are forced by their curricula to register for this course. The ever-increasing numbers in EUC place a considerable load on existing human and physical resources. In lecture groups of 120 –160, students rarely get the attention they need, and the pace at which the content is delivered (too slow or too fast) may also inhibit the learning process. During an initial investigation into E-learning at UPE in 1999, a prototype virtual classroom was developed. There were, however, a number of problems with this prototype. Firstly, it was implemented using a number of different technologies, which made it difficult to extend and maintain. Secondly, it only addressed some aspects of an E-learning environment, which proved insufficient for the EUC course. In the existing EUC course at UPE, the students are already exposed to some E-learning concepts, as a section of their skills training component is handled by using multimedia software in a simulated environment. The objective of this project was to extend the E-learning component further to determine the advantages and disadvantages of using E-learning to support information technology (IT) education in a contact-university environment. This project included a literature search and survey of existing E-learning environments at other universities. This research was used to develop a draft framework for an E-learning environment. The framework was used to select a tool to create an E-learning environment at UPE. An experiment was designed using this E-learning environment to support two IT courses at different year levels. The results of the experiment were analysed using qualitative and quantitative methods to determine the impact of using E-learning to support IT education at UPE. The results of this research show that E-learning can be used to support IT education at UPE. More success, however, was achieved at postgraduate level than at first-year level. Making use of Elearning increased student satisfaction and promoted active learning, while providing benefits like convenience, communication, flexibility and scaffolding. We conclude, therefore, that E-learning can provide a flexible approach to IT education in a university environment in the future.

  • Description: The study reviews the political transition after the first decade of democracy from the trade union leaders’ perspectives. It seeks to understand whether trade union leaders see workers as having reaped benefits from their struggles. Interviews were conducted with ten current and past trade union leaders on their perceptions about the political transition. The trade union leaders that were interviewed have rich experience of combining their organisational and mobilising strength with strategies of engagement. Their involvement with trade unions can be traced back during the dark years of Apartheid. Some of them are still active members of trade unions who are deeply involved in policy formulation at national level. Others occupy influential positions in the private and public sectors. The study investigates and analyses the labour movement’s objectives, strategies and struggles from the apartheid, transition, and democratic eras and into the future. It looks at how these objectives were achieved and how the strategies were implemented. The study revealed that progress was made in the political sphere, e.g. a parliamentary office was established to ensure that workers have a voice in parliament. The study found clear evidence of influence by the labour movement in economic and labour legislation through structures like NEDLAC. In the economic arena, the study found that workers’ economic expectations were partially fulfilled. Trade union leaders attributed this to the failure of the government’s GEAR policy to create jobs. They insisted that RDP should be implemented. The study revealed evidence of serious tensions within the ANC/COSATU/SACP Alliance. The study found that the influence of the labour ally, COSATU, in the Tripartite Alliance had been curtailed. The study also found that the strength of the labour movement eroded during the first decade of democracy. The research found that the labour movement took new initiatives such as union investment companies. The research also found support for the theory that COSATU’s obsession with alliance politics was a barrier to labour unity. COSATU was not involved in the merger talks between FEDUSA and NACTU. The respondents generally felt positively about the future prospects. Respondents were mostly optimistic about the political transformation. If there was slow delivery or no delivery by the government or business, the unions vowed to take to the streets.

  • Description: In this treatise the South African law relating to unfair discrimination is discussed. The development is traced from the previous dispensation and the few pronouncements of the Industrial Court on discrimination in employment. Thereafter the actual provisions in the law presently applicable, including the Constitution is considered. With reference to leading cases the issue of positive discrimination by adopting affirmative action measures is evaluated and reference is made to other defences like inherent requirements for the job and a general fairness defence. The conclusion is reached that South African law is developing to give effect to the notion of substantive equality with a view to eradicate the systematic discrimination of the past.

  • Description: This study presents a description of the development and history of learner support, as well as educational psychological leaner support, in South Africa. The role and function of the educational psychologist was researched through literature study and empirical research. It was found that whereas this pivotal profession is still vital in any educational system, the nature of contemporary society has necessitated a new dimension in educational psychological service delivery, namely systemic involvement. Guidelines for a new model for educational psychological learner support in the education dispensation are put forward. This model asks for the enlargement of the role of the educational psychologist to include assessment and support of all of the systems that play a role in the learner’s life.

  • Description: This paper seeks to bring clarity to a number of issues that arise from a process resulting from the unilateral variation of terms and conditions of employment and the conflict management and dispute resolution processes. The variation of employment terms particularly when it is driven by one party to the employment relationship can cause instability, insecurity, confusion and uncertainty to the parties involved. The nature of work is not constant and therefore changes are inevitable. This then has an effect of bringing disorder not only to the employer-employee relationship but also to the labour relations balance. In many instances and depending on whether it is the employer or employee who propagates the changes, the reasons to alter the conditions are different. Employers usually cite operational or economic reasons that are meant for the survival of the business as the need to make the changes. From the employees’ side the changes are necessitated by reasons aimed at a move from protecting the favourable employment conditions already acquired to improving them or attaining more. In the event that the parties to the employment relationship do not agree to the changes proposed and implemented, a dispute usually arises. This results from the failure of a consultation process, negotiations, persuasion or collective bargaining in general. In essence such a dispute arises from absence of consent to the changes. The failure of a bargaining system requires the process to assume a new nature. The dispute resolution systems and the conflict management systems follow as both the appropriate and necessary steps. The bargaining power together with the intervention of the third party is at the centre of this phase. The parties, depending on the nature of the dispute, the conditions that iv are changed and who are affected by the changes, have choices on what dispute resolution mechanisms to employ. The choice made has a huge impact on both the outcome required in the form of recourse, how the dispute will be resolved or how the conflict will be managed. There is legislative intervention with regards to the resolution of the conflictual scenarios that arise from disputes on unilateral variation of terms and conditions of employment. There are also non-statutory measures available to the parties. The choices are vast as to when can the variation take place, the reasons for the changes, the parties involved, the possible dispute resolution mechanisms, what can be varied and whether the unilateral implementation can be viewed as fair.

  • Description: The study which follows considers the current approach to State sovereignty, use of force, and human rights, in order to determine the balance which exists between these concepts. A shift in this balance determines the direction of development of the concept of ‘humanitarian intervention.’ The investigation establishes that State sovereignty and certain human rights are at a point where they are viewed as equal and competing interests in the international arena. This leads to the question of whether or not the concept of humanitarian intervention has found any acceptance in international law. It is determined that the right to intervention rests exclusively with the United Nations Security Council. There are, however, obstacles to United Nations action, which necessitate either taking action to remove the obstacles, or finding an alternative to United Nations authorized action. The alternatives provided are unilateral interventions by regional organizations, groups of States or individual States, with interventions by regional organizations being favoured. The study further discusses the requirements which would make unilateral action more acceptable. These same requirements provide a standard against which the United Nations can measure its duty to intervene. Such an investigation was done by the International Commission on Intervention and State Sovereignty, and a synopsis of its Report and Recommendations are included. Finally, the question of responsibility is addressed. State and individual responsibility for two separate types of action are considered. The responsibility of States and individuals for initiating an intervention is considered under the topic of the crime of aggression. The responsibility of States and individual for exceeding the mandate of a legitimate intervention is considered under the heading of war crimes.

  • Description: Recruitment and selection has become a specialised industry and is competing in a global market. To remain competitive, recruitment agents have to stay ahead of their competitors, by providing an excellent service to customers and applicants, and by keeping up with technological developments in their field. The current investigation focuses on an assessment of the attitudes of recruitment agents in a selected area of the Western Cape Province to the use of computer-based management information systems as a recruitment tool. A questionnaire was distributed amongst recruitment agents in the identified area. It focused on recruiter biographical information, the services they offer, the methods and processes they use in recruitment, the knowledge and skills they need in their field, and their knowledge and attitude towards electronic-recruitment. The literature indicated a move towards using technology in the field of recruitment, and this was consistent with the findings of the study. Although the respondents were familiar with developments in technology used for recruitment, only a small number were familiar with the major business information systems, namely, SAP R/3, Oracle and PeopleSoft. Information specifically related to recruitment agents in South Africa was limited, but the study provided some insight into this field. It was found that recruitment agents disagree on what a good advertisement, as well as a good résumé, should contain, and this is problematic as these are two of the most important things that recruitment agents work with every day. The literature provided no indication of the qualifications needed by a recruitment agent, and resulting from this, a second finding of the study indicated that, according to the respondents, the qualifications needed by a recruitment agent are varied. It was found that qualifications of the sample group varied from only a school-leaving certificate to post-graduate degrees. A significant trend identified that only 24.2 per cent of recruitment agents are involved in research related to recruitment, and write articles related to their field. This contributes to the fact that so little information is available about South African recruitment agents. The study indicated that recruitment agents hold a positive attitude towards computer-based information systems, although they are accepted with caution because of various logistical problems in the South African market. The study also provided useful information to start a process of drawing up a profile of the South African recruitment agency business.

The unfair labour practice relating to promotion

  • Description: This article deals with the South African law relating to promotions. As promotion disputes mostly arise as alleged unfair labour practices, a short discussion on how the concept of an unfair labour practice developed in South Africa is undertaken. In this regard the common law is studied in order to see whether it makes provision for protection of employees subjected to unfair labour practices relating to promotions. Through this study one soon realises that the common law is in fact inadequate to deal with unfair labour practices relating to promotions, and thus an enquiry into various legislative provisions are undertaken. The impact of the all-important Wiehahn Commission of Enquiry, established in 1979, is also briefly discussed. In this article an attempt is made to define the term ‘promotion’. In this regard reference is made to some cases adjudicated upon by the Commission for Conciliation Mediation and Arbitration (the “CCMA”). The cases referred to seem to favour the view that when one is defining the term ‘promotion’, regard must be had to the employment relationship between the employer and the employee, as well as the nature of the employee’s current work in relation to the work applied for, in order to establish whether in fact a promotion has taken place. It is necessary to consider what unfair conduct is defined as in the context of promotions. It seems that managerial prerogative is at the center of the enquiry into unfair conduct of the employer. Further to the analysis of unfair conduct, various principles that govern both procedural and substantive unfairness are considered. These principles are dealt with separately with reference to case law. Lastly the dispute resolution mechanisms are considered and a brief discussion on remedies is undertaken. The remedies are discussed with reference to case law, as well as the provisions of the Labour Relations Act 66 of 1995 as amended by the Labour Relations Amendment Act 12 of 2002. The broad headings of this article are accordingly unfair labour practices, definition of promotions, unfair conduct of the employer, onus of proof and remedies. It is concluded with the proposition that once an employer has set policies and procedures in place in dealing with promotions, then such an employer should stick to those policies and procedures within the context of the law, as well as within the percepts of the vague and nebulous term of ‘fairness’. Should the employer fail to do so, the majority of cases indicate that such an employer will be guilty of an unfair labour practice relating to promotion.

  • Description: The number of women who choose to combine careers and traditional roles as mothers has been increasing steadily over the last number of years. As a result, the subjective wellbeing of these women has been the focus of many research projects over the last number of years. Subjective well-being has been defined in various ways by different authors. One definition describes subjective well-being as people's evaluations of their lives, which includes happiness, pleasant emotions, life satisfaction, and a relative absence of unpleasant moods and emotions. The current study, which took the form of a multiple case study, attempted to explore and describe White employed married mothers’ subjective experience of their well-being. The study also explored these women's experiences of combining the roles of employee and motherhood. The sample was obtained through the snowballing technique, and both qualitative (in-depth interviews) and quantitative techniques (two questionnaires - the Satisfaction with Life Scale and the Beck Depression Inventory) were utilized. The analysis of the data that was gathered was done by means of thematic and content analyses.

  • Description: The purpose of this project was the specification, design and implementation of a prototype 2-D MPEG-4 authoring tool. A literature study was conducted of the MPEG-4 standard and multimedia authoring tools to determine the specification and design of a prototype 2- D MPEG-4 authoring tool. The specification and design was used as a basis for the implementation of a prototype 2-D MPEG-4 authoring tool that complies with the Complete 2-D Scene Graph Profile. The need for research into MPEG-4 authoring tools arose from the reported lack of knowledge of the MPEG-4 standard and the limited implementations of MPEG-4 authoring tools available to content authors. In order for MPEG-4 to reach its full potential, it will require authoring tools and content players that satisfy the needs of its users. The theoretical component of this dissertation included a literature study of the MPEG-4 standard and an investigation of relevant multimedia authoring systems. MPEG-4 was introduced as a standard that allows for the creation and streaming of interactive multimedia content at variable bit rates over high and low bandwidth connections. The requirements for the prototype 2-D MPEG-4 authoring system were documented and a prototype system satisfying the requirements was designed, implemented and evaluated. The evaluation of the prototype system showed that the system successfully satisfied all its requirements and that it provides the user with an easy to use and intuitive authoring tool. MPEG-4 has the potential to satisfy the increasing demand for innovative multimedia content on low bandwidth networks, including the Internet and mobile networks, as well as the need expressed by users to interact with multimedia content. This dissertation makes an important contribution to the understanding of the MPEG-4 standard, its functionality and the design of a 2-D MPEG-4 Authoring tool. Keywords: MPEG-4; MPEG-4 authoring; Binary Format for Scenes.

  • Description: In South Africa, labour has played a central role in shaping the transition to democracy. It remained an open question as to whether labour could sustain it’s involvement during the period of consolidation after the first democratic elections. As was evident in other emerging democracies, economic liberalization often led to stagnation and high costs being imposed on workers, while weakening the state. South African trade unions thus faced formidable problems as they had to respond to rapid economic and industrial change. While being stubborn, South African trade unions remain adaptable enough to survive and grow into the 21st Century. In this dissertation, the writer examines the relevance of trade unions in contemporary South Africa and how they are coming to terms with the deregulated labour market, and the question of globalisation. We look at the emergence of new forms of collective bargaining, the growth of trade unions as partners in a changing workplace and the different ways trade unions are modernising themselves to attract new members. Labour when used as a collective force is capable of shaping democratization through the strategic use of power. Labour has the potential , through participation in negotiated compromises, to ensure that the costs of adjustments are not borne by workers alone. To this end, the South African trade union movement has developed innovative strategies and institutions.

  • Description: The post-apartheid South African Constitution guarantees the children of this country “the right to receive education in the official language or languages of their choice in public education institutions where that education is reasonably practicable” (The Constitution of the Republic of South Africa, Act 108 of 1996, Section 29 (2)) (Juta’s Statutes 2003). Yet ten years into the new dispensation nothing significant has been done to alter a situation in which the majority of children are obliged to access their basic education largely through the medium of a second or even a third language — English. In contravention of both the intentions and the specific provisions of numerous legislative measures and policy statements, Government has made no serious or effective attempt to promote the use of any language other than English in South African schools nor to encourage language practices most conducive to the cognitive development and academic success of millions of non-English speaking pupils. To make matters worse, most of the children who enter the school system with very little knowledge of English and are expected to make an abrupt transition to that language as a medium of instruction after a totally inadequate three years are from impoverished households and communities still suffering the gravest effects of the discrimination and oppression of apartheid. They are often underprepared and seriously disadvantaged by their background circumstances when they enter the culturally strange and intimidating western-style education system. To heap on top of these disadvantages the burden of language practices in the classroom that hinder rather than facilitate their access to education is indefensible. When Macdonald asks, “ Are our children still swimming up the waterfall?” (Macdonald 2002: 111) she is not exaggerating. In these circumstances and if ineffective language teaching and inadequate use of the mother tongue as a medium of instruction can be shown to bar effective access to basic education of an acceptable standard, there are far more serious and far-reaching implications in terms of human rights than just the right to choice of language medium. Linguistic research into medium of instruction has tended to be isolated from evaluative legal approaches to minority language rights, children’s rights, education rights or other fundamental human rights. Insufficient attention has been given to the interrelationship between the various rights and the importance of local conditions and circumstances in any assessment of their relative weight and enforceability. Human rights cannot be seen out of context, and theory from various disciplines, such as politics, economics and linguistics may be invaluable in forming a fresh perspective on the right to mother tongue education and, indeed, to basic education in general. The principle of non-discrimination in education is generally recognised, to be sure, as is the importance of ensuring access to and quality of education (Strydom 1992/93:139), but the dependence of these factors on the most appropriate medium of instruction within the education system does not merit much attention in the literature. The right to basic education tends to be seen as separate from any possible right to choice of medium of instruction and the latter often merely as a question of convenience or preference, at best a qualified right (Oosthuizen and Rossouw 2001: 666), dependent on feasibility, numbers and available finance (Motata and Lemmer 2002: 111). In fact, the case for regarding the right to mother tongue education as a strong positive right in many contexts and countries does not appear yet to have been made. This study is theoretical in nature and constitutes an attempt to fill this gap by examining the findings and views of experts from various disciplines within the framework of current thinking on human rights issues. The development of a coherent framework within which to view the right to mother tongue education and government obligations in connection therewith might be of some value to policy makers in their efforts to plan improvements within the education system. The synthesis and possibly, to a limited extent, the development of theory from the relevant disciplines will be undertaken by means of a survey of the relevant literature, an analysis of not only local but also international legislation and policy documents and the weighing and balancing of conflicting evidence and contrasting viewpoints. Sources and contributions in each area will be discussed under the headings outlined in Chapter 3. First, however, I should like to provide an overview of the educational, political and economic context in which mother tongue education must be considered.

  • Description: The objective of this treatise is to establish whether a right to social security exists in South Africa, which would entitle HIV positive persons in South Africa citizens to medical care. A study was made of various articles in journals and on the Internet to determine the South African government's policy on a right to social security and to providing medical treatment. It was found that South Africa lacks an integrated, holistic approach to social security and does not guarantee the right to social security, merely the right to have access to social security. The same was found with the right to medical care. Although there seems to be a general right to medical care which extends to and includes HIV-positive patients, the state merely guarantees the right to apply for medical treatment but does not guarantee the granting thereof. It is submitted that the Department of Health's refusal to implement a vertical transmission prevention programme and the failure to offer treatment as an alternative, for whatever reason, is "penny wise and pound foolish". In the long run more money is spent dealing with pediatric AIDS. It was further found that although the government attempted to lay a groundwork with the formulation and acceptance of the national AIDS plan, the successful implementation thereof is seriously hindered due to the lack of inter- and intra-departmental collaboration, essential health services and funding.

The relationship between trait anxiety and anxiety sensitivity

  • Description: Anxiety Sensitivity (AS) is a useful psychological construct in understanding the development of general and clinical anxiety. An increased amount of research has recently been conducted in this area. Since the development of the 16-item Anxiety Sensitivity Index (ASI), there has been deliberation in the literature about the relationship of the AS construct and the ASI, to the personality construct of trait anxiety. Central to this discus sion is the notion that AS is nothing more than trait anxiety. This position brings into question the conceptual and empirical validity of AS. This study aimed to explore and describe the relationship between trait anxiety and anxiety sensitivity, through the use of an exploratory-descriptive correlational design. Levels of trait anxiety were determined through the use of subscales on the Sixteen Personality Factor Questionnaire (16PF) and anxiety sensitivity through the use of the ASI. Using a convenience sampling technique, 84 student volunteers completed the 16PF and ASI. Descriptive statistics and inferential statistics were employed for data analysis. The results indicate that the sample group had the capacity to express emotional energy along integrated channels and was thus well suited for exploring the relationship between the construct of trait anxiety and anxiety sensitivity. The relationship between trait anxiety and AS in the sample group was explored through the use of two statistical procedures. Firstly, the coefficient of determination (r²) was calculated and revealed that 24% of the variance among the ASI scores were attributable to variations in Factor QII scores of the 16PF and viceversa. Secondly, a multiple regression analysis technique revealed that 28% of the variance in the ASI score could be explained by the combination of factors Q4 (free- floating anxiety), O (guilt proneness), C (ego strength), L (suspiciousness), Q3 (ability to bind anxiety) of the 16PF. These key findings are in line with other research in that the constructs of trait anxiety and anxiety sensitivity showed a level of variance. As such, it was concluded that although the constructs may be related, they are not synonymous.

  • Description: This treatise provides an overview of the procedures for the registration, regulation and protection of Internet domain names. An analysis of legal rules applicable to domain names and problems related to the protection of domain names in South Africa, United State, United Kingdom and internationally is undertaken. The problems includes cybersquatting, misuse of personal names, reverse domain hijacking, misuse of meta tags and keywords. The treatise established possible solutions applicable to South Africa by investigating how other countries have dealt with such problems, and further investigated the extent to which South African legislation is suited to deal with such problems. An investigation of the regulation in terms of the Electronic Communications and Transactions Act 25 of 2002 is briefly attempted, and proposals for the future on the South African domain name system suggested.

  • Description: In this unique time of nation building in South Africa, education is seen as the key foundation stone to prosperity and development. However, despite a decade of restructuring, many differing groups of children still do not receive the quality of education they deserve. Amongst those are children with special needs, including those who have a hearing impairment. These children are the focus of the present study. It is a widely accepted principle that early assessment and intervention is necessary to maximise a child’s potential. It is for this reason that the global aim of this study was to explore and describe the developmental profile of hearing impaired children on the Revised Extended Griffiths Scales. Further aims were to compare the performance of the clinical sample to a normal South African sample. A quantitative, exploratory-descriptive research design was employed. The sample of hearing impaired children (N = 58), between the ages of 36 and 95 months, attended the Carel du Toit Pre-School in the Western Cape, South Africa and were obtained by means of a non-probability, purposive sampling procedure. The normal sample (N = 58) was drawn from an existing database created for the revision of the Scales. Information was collated using clinical files, biographical data as well as the results of an assessment on the Revised Extended Griffiths Scales. The major findings of the study are summarised below. The general performance of the hearing impaired sample on the Revised Extended Griffiths Scales was average. The performance of the children on the six subscales ranged from below average to average, with major fall-outs occurring on the Hearing and Speech and Practical Reasoning Subscales. The normal sample performed significantly better than the hearing impaired sample on all of the subscales of the measure. However, significant differences were found on four of the six subscales, namely, the Locomotor, Personal-Social, Hearing and Speech and Practical Reasoning Subscales. Generally, the results of the current study suggest that a specific developmental profile is obtained for hearing impaired children. In addition, this study has highlighted the success with which the Revised Extended Griffiths Scales can be utilised on a hearing impaired population.

  • Description: Despite a widespread perception that the number of children coming to clinical attention with Autism Spectrum Disorders has greatly increased, limited South African Research has been conducted on children with Autism. Thus a need exists to accumulate knowledge about the cognitive, psychological and personalsocial growth of children diagnosed with Autism. This study is aimed at exploring the performance of children with Autism between the ages of 7 years (from 72 months) and 8 years (to 95.9 months), in South Africa (SA), utilising the Revised Extended Griffiths Scales of Mental Development (GSMD). The sample comprised an experimental group of 30 children with Autism from four schools for Specialised Education for learners with Autism in SA, and a control group comprised of 30 “normal” children, where normalcy can be broadly defined as “an absence of any sensory, physical or mental handicap”. The six areas of general development assessed included Locomotor, Personal- Social, Language, Eye and Hand co-ordination, Performance, and Practical Reasoning. A non-probability, purposive sampling method was applied. The major findings of the present study were as follows: (i) Children with Autism (years 7 & 8) showed a characteristic cognitive profile when tested with the revised Extended Griffiths Scales. Their performance indicates lower performance on Subcales B, C and F than on the other Subscales. (ii) Some children with Autism experienced major fall-outs, whereas others were slightly below average. The general performance of children with Autism was, however, in the range “cognitively impaired”. (iii) There was significant difference between the Autistic sample and the normal sample on the GQ. xiv In view of the findings, it is recommended that the results of the study, which focused on the children’s areas of developmental weakness, be widely disseminated. This could facilitate the development of therapeutic programmes, so as to allow for appropriate stimulation for children with Autism.

The nature and potential effect of the Labour Relations Amendment Act 2002

  • Description: It took 18 months of intensive negotiation at the Millennium Labour Council, NEDLAC and the Labour Portfolio Committee before the Labour Relations Amendment Act of 20021 completed its passage through Parliament, taking effect on 1 August 2002. Fifty-seven amendments to specific sections of the Labour Relations Act2 and its schedules cure some obvious anomalies in the original version. It is further apparent that the legislature has taken cognisance of the observations by judges and arbitrators, who voiced their criticism in respect of certain aspects of the original "Act". The amended "Act"3 does appear to be a genuine commitment by both business and organised labour to improve efficiency in the labour market, to promote employment creation and to protect vulnerable workers. Improved dispute resolution mechanisms, enforcement mechanisms and the resurgence of an unfettered discretion in awarding compensation go some way to improving the application of the "Act". The most dramatic amendments have taken place in the law regulating retrenchments by large employers, inclusive of the controversial introduction of a right to strike after retrenchments of this nature have been effected, and the regulation of the transfer of a business as a going concern and its impact on workers. Critics indicate that business and organised labour have subscribed to the package of amendments despite respective reservations and due to certain time constraints. The nett result is a package of amendments that could be described as failing to address, in certain respects, or intentionally overlooking, areas of the "Act" that have traditionally been shown wanting in the past. In the individual employment law sphere specifically, the failure to address the meaning of "benefits" in the definition of unfair labour practices; to allocate a precise meaning to the concept of the transfer of a going concern; or to regulate the conduct of employers when transferring employees, remain some of the areas for concern. It appears that the legislature has decided that certain issues should be resolved by the Labour Court, and ultimately the Labour Appeal Court, on a case-by-case basis rather than by legislative intervention. Whilst this approach has merit, it does present problems to those seeking to apply the provisions of the amended "Act" 5 in everyday practice. On the whole, the amendments do not, nor were they designed to, mark a major shift in the government's labour market policy. The changes clearly focus on correcting and clarifying sections of the "Act", which have resulted in unintended consequences, or lost touch with commercial reality, over the past seven years.

  • Description: The isomers of cyclo(Trp-Pro) (cyclo(L-Trp-L-Pro), cyclo(L-Trp-D-Pro), cyclo(D-Trp-LPro) and cyclo(D-Trp-D-Pro)) have been successfully synthesized and screened for biological activity. High percentage yields were obtained by using the three phase synthesis system, which involves the synthesis of the intermediate protected linear dipeptides, followed by the removal of the protecting Boc groups. This step is followed by cyclization and crystallization of the isomers. The diketopiperazines rings of cyclo(L-Trp-L-Pro) and cyclo(D-Trp-D-Pro) contain cisamide bonds, while cyclo(L-Trp-D-Pro) and cyclo(D-Trp-L-Pro) contain trans-amide bonds. These bonds govern the conformation of the diketopiperazines ring. The isomers have shown different degrees of biological activity, possibly as a result of the orientation of the side chain of tryptophan and this difference in conformation, leading to varying interactions between isomer and a range of receptors. Under experimental conditions, 10-3 M cyclo(L-Trp-D-Pro) and cyclo(D-Trp-L-Pro) showed effective anticancer activity against the cervical cancer cell line, HeLa, resulting in a <50% reduction in cell viability. Cytotoxicity screening with cyclo(D-Trp-L-Pro) indicated that it was hepatocyte-specific in its toxicity, whilst the other isomers were cytotoxic against the other cell types tested. At 1mg/ml, cyclo(L-Trp-L-Pro) proved to be an effective antimicrobial agent against Gram positive bacteria, while cyclo(L-Trp-DPro) effectively inhibited the growth of the Gram negative bacteria, Esherichia coli. Cyclo(D-Trp-L-Pro) proved to be effective against Streptococcus, while cyclo(D-Trp-DPro) effectively reduced viability of the yeast, Candida albicans. Cyclo(D-Trp-L-Pro) was the only isomer to show Ca2+-channel antagonism, whilst the other isomers resulted in opening of the Ca2+-channel. No effects were observed on K+-channel activity for all the isomers tested. The isomers also proved to be valuable antiarrhythmic agents by effectively reducing the time spent in ventricular tachycardia and arrhythmia, as well as decreasing the time for the heart rate to return to a normal sinus rhythm. Furthermore, cyclo(L-Trp-D-Pro) showed positive chronotropic activity, while cyclo(D-Trp-L-Pro) ii showed negative chronotropic activity. In addition, cyclo(L-Trp-D-Pro) and cyclo(D-Trp- L-Pro) also increased the coronary flow rate. 0.125 –1 mM Cyclo(L-Trp-D-Pro) decreased aggregation in washed platelets induced by thrombin. All isomers increased adhesion to an artificial surface when the platelets were stimulated by ADP, yet caused reduced adhesion when the platelets were stimulated by thrombin. These results prove the potential of these compounds as novel agents in a range of biological fields, indicating that a combination of L- and D- amino acids may prove more effective than an agent consisting solely of L-amino acids.

  • Description: Sports law in South Africa is a field requiring exciting and intensive research. With so many sporting codes changing their status to professional sport, intensive research on the legal implications pertaining to each professional sporting code has also become necessary. Professional rugby in South Africa has grown into a multimillion rand industry. It is an industry whose role players need specialized legal advice on a multitude of issues. This dissertation addresses the legal issues arising out of the situation where a professional player is injured, during practice or a game, due to the intentional or negligent action of another. The medico-legal aspects of rugby, relating to causation and proof of injuries are an indispensable element of proving liability where rugby injuries are concerned. These aspects are crucial in assessing the criminal and delictual liability of players, coaches, referees, team physicians and even the union concerned. The problem of rugby violence, causing injury, is addressed by both the criminal law and the law of delict with the issue of consent being central to this discussion. Furthermore, the labour law implications can be far-reaching for both the player and the employer union due to the unique features of sport as an industry. All role players in professional rugby will have to cooperate with the legal community to ensure that a practical body of law is established in order to make rugby a safer sport for all concerned and to protect the professional player from unnecessary, incapacitating injury.
