- 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 new political dispensation in South Africa has seen a lot of changes taking place. The democratic wind, which has been blowing in all spheres of the political arena, could not leave out Education. This has led to the transformation in education and the revision of the curriculum guided by the Outcomes-Based Education philosophy (OBE). Thus, require education authorities as well as educators to look at education more comprehensively. The challenge posed to educators now is to develop tools and strategies that will make learning accessible to as many learners as possible and to teach for understanding and construction of knowledge. The principal objective of this study was to investigate the important role the learner's prior knowledge plays and the use of different tools and strategies in stimulating conceptual understanding and construction of knowledge of redox reactions. This was done using learners' own investigations, practical activities, teaching settings and a workshop. The findings show that the learners lacked organized and structured prior knowledge. Learners could not integrate prior experience with new experience. The main issue seems to be the failure of learners to relate classroom experience to everyday redox phenomena. Possible reasons are discussed with some implications for teaching redox. The study further postulates that to assist learners to develop conceptual understanding of redox reactions, different tools and strategies should be employed and teaching made relevant to real-life situations. In so doing, redox concepts would not be abstract to learners.

- Description: This interpretative case study derives and examines the characterising features of the resource-based learning approach used in the Rhodes University Advanced Certificate in Environmental Education (ACEE), particularly in Module 1 (Environment and Environmental Issues) and Module 3 (Contemporary Environmental Issues). The study explores processes of resource-based learning through the analysis of three individual case stories of participants’ experience in adaptive use of learning support materials in different work contexts. It discusses the relationship between thematic categories related to participants’ experience of assignment work, and course design and course implementation. This study indicates that resource-based learning processes in the ACEE involve curriculum deliberation and the use of resource packs in supporting participants’ practice. It also indicates that the ACEE’s practice-based orientation to workplace-based assignments plays an important role in supporting the adaptive use of learning support materials, encouraging lifelong learning and developing applied competence. It highlights the significance of reflexive narration of practice in improving course participants’ educational practice. A diagrammatic representation of the unfolding and intermeshed characterising features of resource-based learning is presented. The study argues that resource-based learning in the ACEE appears to create possibilities for the course participants to become scaffolders and co-constructors of their own learning. It notes that resource-based learning can enable course participants to take ownership of their educational and workplace needs, and to develop skills and competences necessary to respond to environmental issues and risks in southern Africa. This study examines the potential that the reflexive narration of practice has in supporting course participants to engage in better ways of doing things in their workplace-based contexts. This study provides some recommendations to enhance the Advanced Certificate in Environmental Education as well as some ‘fuzzy generalisations’ that might guide the Southern African Development Community (SADC) Regional Environmental Education Programme (REEP) in the development and adaptation of professional development courses in southern Africa.

- Description: What is the portfolio and what are its purposes? I must define the portfolio as a summative document bearing the valuable experiences learned in a particular course of study. In this context, portfolio can be viewed as a selective entity that represents the level of learning, in terms of academic/professional growth and development, attained in one's participation in a particular course of study such as this Master one I have been attending. Portfolio can be educationally utilized to reflect and evaluate one's learning. As one goes throughout paging, one locates the level of learning achieved in terms of anticipated knowledge, understanding, and experiences, skills and attitudes or overly learning competencies. The level of development one has gone through in attempts to respond to the expected learning outcomes surface out more easily. And if further learning be conducted, the portfolio must as well shows the ways ahead. With these few words, I have attempted to present the portfolio as a useful tool that represents the level of advancement attained in learning. This portfolio comprises of my educational partaking in Rhodes University's master program (theory and practice, in particular what and how I have gained from that program participation. It may also present what I cold not learn. The arrangement of the portfolio contents assumes a progressive procession, being structured in terms of the assignments taken. There are five pieces of assignments in this research portfolio. The first assignment is a contextual analysis of the Education Theory and Practice (ETP) curriculum of our current teacher education program, namely Basic Education Teachers' Diploma. It looks at the theoretical framework that informs and shapes everyday teaching and learning practices, particularly the degree to which we have been able to implement the theoretical perspectives into operational practices. To this is how our college is equipped with the technologies necessary for possible practices of the curriculum. The other emphasis focuses at the historical backgrounds that necessitated the undertaking of the BETD as an instrument of reforming and transforming the basic education rightly at the independence. The other area is on the question of how the curriculum or program intakers, the entering students, have been prepared to consume the curriculum program. Since the program has been as well designed to address and meet the four major national goals of education for all, another part has been focused on these goals so far as to locate the degree of attainment. The second assignment is about contrasting and comparing the two main held dominant worldwide views of knowledge- namely behaviorism and constructivism. Each branch of knowledge is looked at firstly with particular attentions paid to its own individual versions of knowledge and its development and acquisition. The other focuses examine which base seems to offer better explanations of what knowledge is and how it can best be constructed and acquired in any educational setting. The third assignment is that of literature review. I have chosen action as an area that I would be interested in exploring much further. Action research is what eventually became a part of my research proposal in which I would research on how our college students carry out their action research projects to examine their own classroom makings. It has been therefore important to read what others have written about this field and locate the lessons that can be illuminated on our own curriculum context. The literature review paves the way to the research proposal. The research proposal or a research plan as I would often call it, sets the context, purpose, theoretical position and information gathering methods under which the research process will take place. The research proposal has thus been the navigating compass despite the that realities as the practical journey itself took off some deviation unavoidably came in as necessitated by the underlying research process itself. The research proposal finally accumulates into the sought, the final assignment. A critical view illustrates that this piece is actually another contextual inquiry like the first work only that this is viewing our supposed curriculum outcomes: our students, our products and how they have been equipped to carry out the research. Their research, with its successes and shortcomings, I have concluded, firmly serves to reflect the kind of education delivered from our teacher colleges. The portfolio contents also demonstrate the course orientation: focusing on one's professional field. At end, I see this research portfolio as myself, a mirror that reflects my academic and professional participation in Rhodes University's world and its vision and mission expresses in the theme of where leaders learn. It thus represents the personal, academic and development accomplished throughout this Masters' course. In the other way around, I see it as reflecting what Rhodes can offer as from when the prestigious Augustana College, my American institution, has prepared after its boundaries.

- Description: The aim of the study was to evaluate the effect of ozone (O3) on mature body weight (MBW), feed conversion rate (FCR), mortality rate (MR) and ammonia (NH3) production of broiler chickens (referred to as “broilers” in this thesis) under controlled conditions. Ozone was used for the purifying of air and water in order to eliminate harmful microorganisms. Two trials were conducted over a twelve week production period. In experiment 1, day old broiler chicks were randomly allocated to a control (n=130) and treatment (n=130) group. The treatment groups were exposed to ozone continuously for the entire period of the trial. Both air and water were ozonated on a 24 hours daily basis, while the control group was reared under normal commercial conditions. In experiment 2: day old broiler chicks were randomly allocated to a control (n=123) and a treatment (n=123) group. The treatment group was exposed to ozone for 3 hours per day for the entire period of the trial. Both air and water were ozonated, where the air was treated for 3 hours/day and the water for 1 hour/day during the entire production period. The control group was reared under normal commercial conditions. The results indicate that broilers exposed to continuous O3 (0.1 ppm) conditions had significantly higher (P< 0.001) mortality rates than the control group. The treatment group had a mortality rate of 55.38% compared to the 5.38% for the control group. No significant difference (P= 0. 2468) for MBW was found between the broilers that were reared in the O3 environment compared to the control iii group. Although the control group were on average 200g heavier at the end of the trial. No significant difference (p = 0. 6143) was recorded in FCR between the O3 and control groups. However the FCR of the broilers treated with O3 was lower by 100g than that of the control group. The O3 significantly (P< 0. 0001) reduced the NH3 in the treatment group. When the trial was repeated with limited exposure to an O3 environment there was no significant difference in MBW (P = 0. 0979), FCR (P = 0. 8913) and MR (P = 0. 1108) between the treatment and control groups. However, ammonia levels were lower in the treatment group compared to the control group. When the data was further analyzed comparing the two trials, the results indicated that there was no significant difference (P = 0. 4112) in the MBW for the broilers reared under normal conditions (control group) from experiment 1 and experiment 2, while a significant difference (P = 0. 0002) was recorded between the broilers reared under continuous O3 and regulated O3 conditions from experiment 1 and experiment 2 respectively. When the FCR data was analyzed using the Gompertz equation a significant difference (P = 0.0403) in the FCR of broilers reared in the control group between experiment 1 and experiment 2 was recorded (Table 8). No significant difference (P = 0.3226) in the FCR of broilers raised under O3 conditions of continuous and regulated O3 production were reported between experiment 1 and experiment 2. A highly significant difference (P = 0. 0001) in the MR of broilers reared under ozone conditions was recorded between experiment 1 and experiment 2. In experiment 1, the MR was 55.38% while in experiment 2 the MR was only 8.78%. A significant difference (P = 0.0355) was also recorded in the MR of broilers that iv were raised in the control groups between experiment 1 and experiment 2. The MR for broilers in the control group was 5.38% in experiment 1 and for experiment 2 it was 9.74%. The mortality rate of broilers raised in the control groups conditions increased by approximately 4% points or 81% between experiment 1 and experiment 2. The level (0.1 ppm) of ozone production had a limited effect on the MBW and FCR of broilers, however it is evident that ozone is toxic to broilers when they are exposed to a continuous ozonated environment. Ozone was however effective in controlling ammonia levels.

- Description: This work is a school-based case study conducted amongst learners of a rural High School and the immediate community in Whittlesea in the Eastern Cape where I teach. The research was conducted by using different research methods such as worksheets, questionnaires, interviews, practical activities and observations as well as photographs to investigate three indigenous wild local vegetable food plants (imifino). The fundamental assumption of the research is that, imifino can be looked after and cared for, to become valuable vegetable food plants which can be used as supplements to the cultivated vegetable food plants (umfuno). The question was: How could this concept be brought into the curriculum? It had also been assumed that bringing knowledge of imifino into curriculwn contexts could be of benefit to South African learners. The study produced a variety of findings: • There is a general feeling that those who eat imifino are the poor. • There is a lack of interest among women interviewed in the preparation process, for example going to pick the food plants from the fields, washing them and preparing the leaves as food. • AmaXhosa males look upon eating imifino with contempt. • Some males among the younger generation are beginning to overlook tradition and are eating imifino. • Inclusion of indigenous agricultural knowledge in the curriculum was supported by learners and community members. Learners have interest in knowing about indigenous food plants. • Learners feel as Africans that they must learn about the indigenous food plants in school in order not to lose knowledge of these plants completely. • The study also identified that interpretation of learning outcomes with an indigenous knowledge focus, requires careful attention to socio-cultural factors, and not just technical/ practical factors. Previous knowledge of learners and community members about imifino was mobilized to develop a sample OBE learning programme unit (LPU /Lesson plan) for the Grade 10 FET of Agricultural Science curriculum. The case study illustrates that Learning outcome 3 of the Agricultural Science subject can be achieved if educators involve learners and community members in developing learning programmes.

- Description: This work is a school-based case study conducted amongst learners of a rural High School and the immediate community in Whittlesea in the Eastern Cape where I teach. The research was conducted by using different research methods such as worksheets, questionnaires, interviews, practical activities and observations as well as photographs to investigate three indigenous wild local vegetable food plants (imifino). The fundamental assumption of the research is that, imifino can be looked after and cared for, to become valuable vegetable food plants which can be used as supplements to the cultivated vegetable food plants (umfuno). The question was: How could this concept be brought into the curriculum? It had also been assumed that bringing knowledge of imifino into curriculwn contexts could be of benefit to South African learners. The study produced a variety of findings: • There is a general feeling that those who eat imifino are the poor. • There is a lack of interest among women interviewed in the preparation process, for example going to pick the food plants from the fields, washing them and preparing the leaves as food. • AmaXhosa males look upon eating imifino with contempt. • Some males among the younger generation are beginning to overlook tradition and are eating imifino. • Inclusion of indigenous agricultural knowledge in the curriculum was supported by learners and community members.

- Description: The present product development project was aimed at studying the synergism and/or antagonism amongst various known insect repellent actives with the view to formulating a multi-active repellent product with improved properties when compared to current single-active commercial products. Advanced statistical methods were used to identify synergism between individual active substances and to define a formulation as close as possible to the “ideal” formulation. Several mosquito repellent samples were prepared and sent to the South African Bureau of Standards (SABS) in Pretoria to test for their efficiency in repelling mosquitoes. From the results of the repellency tests of the various active combinations, three actives were identified that showed promising signs of synergism. These actives were then studied in further detail to determine their optimum combination. In addition, it was shown that when using a natural flavourant as promoter and incorporating a slow-release agent into formulations for aerosols and lotions, a product is obtained that gives comparable levels of efficiency to current commercial products, but at much reduced levels of active loading. Accelerated stability tests performed on the final combination of the three actives used in the final formulation showed no adverse reactions over a three-week study. These tests shall be repeated once the final application form (lotion, aerosol, etc) and product packing have been decided.

- Description: Prior to the democratic elections of 1994, South Africa was daunted by legislation flooded with racial segregation. Adoption across racial lines is, because of South Africa’s racially segregated past, a relatively recent phenomenon in this country. The number of legal adoptions has increased dramatically, especially after its legalization in 1991. Parents may adopt across racial lines for an array of different reasons, from not being able to conceive a baby, to wanting to give a child the best opportunity in life. This study explored the experiences of white parents who have adopted black children, paying particular attention to how they deal with issues of “racial” identity. In-depth interviews were used to generate qualitative data pertaining to the parental perceptions of their motivation for, and experiences of adopting a child transracially in South Africa. The study aimed to explore their motivation for adopting and experiences, as well as issues relating to “racial” identity. Recommendations have been made to assist parents who are interested in adopting transracially. The report presents findings relating to the unique characteristics of the participants who have adopted transracially. These include adopters’ motivation and thought processes before taking the relevant steps to adopt transracially; the support that they have received from others in their decision to adopt transracially; communication patterns; their relevant concerns regarding the future of their adopted child; and issues pertaining to race, culture, heritage, prejudices and stereotypes. The findings suggest that parents were pragmatic, without regrets, in their views about adopting across racial lines. The parents’ motivations for adopting across racial lines were very similar to various perspectives, but were all due to the fact that they were unable to have biological children. Parents were aware of the child’s identity and cultural issues, which may be more perceptible in the future. Their perceptions, views and opinions, and the future concerns of their children were not unrealistic. Due to the children’s young age a follow-up study of these children should be considered.

Jah children the experience of Rastafari children in South Africa as members of a minority group with particular reference to communities in the former Cape Province

- Description: This thesis is an ethnography of Rastafari childhood in the former Cape Province, South Africa, through the eyes of both parents and children. If children are a ‘muted group’, then what are the identity formation implications for “double-muted” groups, the children of ethnic minorities whose voices are not heard? Rasta parents’ experience of the struggle, ie. the opposition to apartheid, has shaped the Rastafari chant of ‘equal rights’ and ‘justice’ into a distinctly South African form of protest and resistance. Their childhood experiences have resulted in a desire to provide a better life for their children, using Rastafari as a vehicle. This is expressed in a continuation of the struggle that was started during apartheid, in the Rasta ideology children grow up learning. The Rasta child has become a contested body in this struggle. The South African Government, through policy, has a mandate to protect the child, and legislature exists to do so in accordance with international law. However, as child-raising differs phenomenally from culture to culture, these goals on the part of the State start infringing upon the rights and freedoms of minorities to raise their children according to their own cultural goals. This study examines the tension between Rastafari and government with regards to child raising, specifically looking at the following main points of contestation: public health, public schools and policy/legislation; in order to examine how Rasta children negotiate their identity in the face of these conflicting messages and struggles. Their identity can be influenced by three main groups, the Rasta family they grow up in; school; and multi-media. What these children choose to accept or reject in their worldview is moderated by their own agency. This study shows that this tension results in a new generation of Rastafari children, who are strongly grounded in an identity as Rastafari and take pride in this identity. It also illustrates how Rastafari are impacting on and changing government policy through resistance. Their successes in challenging the state on the grounds of multiculturalism and religious freedom, has helped in the attainment of a sense of dignity.

- Description: This thesis examines the ideal of authenticity: why we might want or need such an ideal, what such an ideal would look like, and what mechanisms we would need to ensure the successful operation of such an ideal. The thesis has three main parts. The first part of the thesis aims at motivating the need to look to authenticity as a supplementary ideal to normative moral theory. I do this by drawing a distinction between ethics and morality and arguing that there are important aspects of our lives (such as our relations to ourselves) our beliefs and projects) about which normative moral theory fails to give us guidance and about which an ethical ideal, namely that of authenticity, can provide us with the requisite guidance. The second part of the thesis elucidates Nietzsche's view of authenticity as eternal return. I argue that eternal return consists in holding a particular attitude to one's life - one's past, present and future. I then demonstrate that what is fundamental to successfully living authentically in accordance with eternal return is a rigorous search for self-knowledge. In the third part of the thesis I argue that, in order to achieve the self-knowledge necessary to being a successful authentic agent, one must acquire it through a process of dialogue with other agents. I give a model of self-knowledge as a dialogic encounter that provides two important mechanisms whereby such self-knowledge can be gained.

The challenge of applying systematic conservation planning to the marine environment using expert knowledge (focus: Sparidae)

- Description: Although the marine environment has generally been considered to be less in need of attention from conservationists, politicians and managers than the terrestrial environment, there has been an increasing appreciation that there is little left in the marine environment that can be considered unaltered by humans. Conservation action is therefore urgently needed to protect marine populations, species and environments from anthropogenic pressures. Since overharvesting seems to be the main cause of the collapse in coastal ecosystems, areas need to be protected so that stocks can recover. However, the proclamation of such marine protected areas (MPAs) need to be well planned to ensure that species are well represented and that their biological requirements are met in the long term. While terrestrial conservation planners have started to incorporate biological, social and economic information into so-called systematic conservation plans, marine planners have been more hesitant to use these approaches due to the greater openness of the ocean (with the associated greater dispersal of marine organisms and propogules, lower levels of endemism, and lack of ownership) and the paucity of available information. The current study aimed to investigate the applicability of systematic approaches to the process of selecting sites for a network of potential replenishment zones for seabream species that could supplement protection already afforded by existing no-fishing reserves. Since many of these seabream species are popular targets in both the recreational and commercial linefishery sectors, they have been overexploited and are in need of additional protection. Information on these species and the diversity of their associated reefs were obtained through consultations with scientists, managers and resource-users (namely SCUBA divers, spearfishers as well as recreational and commercial fishers). These data were obtained during workshops where Participatory Rural Appraisal (PRA) scoring and mapping methods were applied. Although ordinal-scale, rather than interval-or ratio-scale data were obtained, these data could be used in an interactive selection process. Because these methods require relatively cheap materials and few personnel, they could be used to collect information where limited budgets are available. Quantitative targets for the protection of individual species were set on the basis of their status in the Marine Living Resource Act, since this reflected their different requirements for protection. A preliminary investigation indicated that the current no-fishing reserves effectively achieved most of these goals for seabream species. The selection of sites for the replenishment network was based on irreplaceability analyses, while decisions between sites with lower irreplaceability values were based on explicit design rules. A total of 26 sites were required to achieve targets for all species. These replenishment zones could potentially be established, managed and monitored by voluntary community groups. This study therefore indicated that systematic conservation planning can successfully be applied to the marine environment, while the involvement of stakeholders is crucial to ensure that conservation action is supported.

- Description: The objective of this study was to investigate the extent to which small to medium-sized building contractors beneficially utilise the financial management function in their enterprises to improve and ensure business sustainability. Financial management focuses on the principles of decision-making, which requires action, without perfect knowledge of the outcome. To effectively execute the financial function, using the primary inputs in decision-making, financial management requires the ability to: understand and interpret financial statements and reports; make reasoned and objective decisions in controlling the operations of the enterprise; have a thorough knowledge of the internal functioning of the enterprise; and have a thorough knowledge of current and expected future economic conditions in the external environment. To do this, requires an effectively applied financial management function in the enterprises, which includes the utilisation of the financial management criteria to ensure business sustainability. However, without an appreciation of what financial management is, how important financial management is, and how financial management must be applied in the enterprise, small to medium-sized building contractors will find it difficult to effectively perform the financial management function and its different activities. It was therefore important to determine how well owners and construction managers of the average small to medium-sized building contractor deal with and utilise the financial management function in their enterprises. Consequently, a survey was carried out amongst small to medium-sized building contractors in the Nelson Mandela Metropolitan Municipal (NMMM) area, which revealed information that was used to come to certain conclusions: Firstly, it can be concluded that the financial management function is generally exercised superficially. This is supported by the responses of small to medium-sized building contractors, which implied that more than half the contractors do not fully perform financial management tasks. Secondly, it was concluded that the financial management criteria generally do not play a role in the business sustainability considerations of small to medium-sized building contractors. This is supported by the results, which imply that more than half the contractors do not fully utilise the financial management criteria.

This is achieved by evaluating the perceptions and expectations of the production department with regards to the service quality provided by the maintenance department of a South African motor vehicle manufacturer. This was done using the INTSERVQUAL instrument, which was found to be a reliable instrument for measuring internal service quality within this context. A positivist approach has been adopted in conducting this research. There are two main hypotheses for this study: the first hypothesis is concerned with the relationship between the overall internal service quality and the five dimensions of service quality namely: tangibles, empathy, reliability, responsiveness and reliability. The second hypothesis focuses on the relationship between the front line staff segments of the production department and the five dimensions of internal service quality. The results of this research suggest that the perceptions and expectations of internal service customer segments plays a major role in achieving internal service quality. In addition, the importance of the INTSERVQUAL instrument in measuring internal service quality within the motor vehicle manufacturing environment is confirmed.

- Description: This research will focus on the influence of legislation (as indicated in this research) on the investment decision in residential income-producing property. Assumptions, as recorded in the hypothesis of this study, indicate that the legislation had a changing influence on the investment decision in residential income-producing property in comparison to the time period prior to the promulgation of the legislation. The research methodology will be based on a comparative analysis of the current legislation and the proposed Draft Amendment Bill. This analysis will be tested by means of a case study analysis incorporating a phenomenological study based on written data. The problems, sub-problems and hypothesis will be addressed and tested in this research in conjunction with the prescribed research methodology. This research is concluded by means of a synopsis and recommendations.

- Description: Labour law in South Africa has evolved over the past century at an ever increasing pace. The establishment of a democratic government in 1995 has been the trigger for a large number of labour law statutes being promulgated, particularly with reference to the laws governing the employment relationship and dismissal. From very humble and employer biased dispute resolution application under the common law of contract, labour law in this country has evolved through the various acts culminating in a labour law system which is highly regulated and codified. Dismissal for medical incapacity in this treatise is reviewed with regard to the applicable statutes and the various codes of good practice as the law has evolved and developed from the period covered by the common law through that covered by the 1995 LRA up to and including the current period. Particular attention is paid to both substantive and procedural requirements as well as the remedies applicable under the different legal regimes and the pertinent tribunals and courts. Regard is also given to the duration and causes of incapacity and the effect this may have on the applicable remedy applied by these tribunals. It will become apparant that the medically incapacitated employee occupied a relatively weak and vulnerable position under the common law as opposed to the current position under the 1995 LRA. The influence of the remedies applied by the tribunals under the 1956 LRA are clearly evident in the current regulations and codes under the 1995 LRA which contain specific statutory provisions for employees not to be unfairly dismissed. Distinctions are drawn between permissible and impermissible dismissals, with medical incapacity falling under the former. v Furthermore, a distinction is drawn statutorily between permanent and temporary illhealth/ injury incapacity with detailed guidelines for substantive and procedural fairness requirements to be met by employers. The powers of the specialist tribunals (CCMA, Bargaining Councils and Labour Courts) are regulated by statutory provisions and deal with appropriate remedies (reinstatement and/or compensation) a wardable in appropriate circumstances. Certain specific areas nonetheless still remain problematic for these tribunals and hence questions that require clear direction from the drafters of our law are: 1. How to distinguish misconduct in alcohol and drug abuse cases? 2. What degree of intermittent absenteeism is required before dismissal would be warranted? In certain other areas the tribunals have been fairly consistent and prescriptive in their approach and remedies awarded. Included here would be permanent incapacity, HIV cases and misconduct. It will emerge, however, that under the 1995 LRA the position of employees and the protections afforded them have been greatly increased.

An analysis of group adverse impact in selection strategies of a communications company

- Description: An overview of the literature indicates that there is a real and pressing need to explore the concept of adverse impact in more detail. The Employment Equity Act of 1998 prioritises the issue of group representivity in staff selection and although there are merits in enforcing an Affirmative Action policy, an objective assessment of the inherent requirements of job applicants is still a constitutional and procedural outcome. There is no simple mechanism that can be used to determine the manifestation of adverse impact. However, evidence thereof can be most useful in securing fairness in selection and employment decisions. There is a distinct need to examine the matter of adverse impact and its implications in the South African context. South Africa is confronted with a labour force that is growing dramatically and changing significantly. The demographic trends in our dynamically changing labour markets are likely to amplify skill and ability differences between the resulting contradictory goals of equal opportunity based on individual merit and equal employment results for subgroups of populations. Three selection strategies of a communications company were used as a basis for the assessment of adverse impact. The total population of the Call Centre selection strategy was 150. Seven instruments and measures were utilised in the study, namely, a job analysis, pre-screening exercise, psychometric ability tests, role-play simulation, structured interview, job compatibility questionnaire and a performance evaluation. The total population of the Operator Services selection strategy was 139. Five psychometric instruments were utilised in the study. The total population of the Female Leadership Development Programme selection strategy was 471. Three psychometric instruments were utilised in the study. The Adverse Impact Model was applied to each of the aforementioned strategies. In terms of the definition, adverse impact exists if the selection ratio associated with a particular passing score on a test for one sub-group of job applicants is less than 4/5th’s or 80% of the selection ration for the largest sub-group of applicants. 13 The results of the study indicate that adverse impact occurred in the following instances. In the Call Centre selection strategy, there was evidence of adverse impact in the racial analysis in the ability testing stage. There was also evidence of adverse impact in the gender analysis during this stage. There was no evidence of adverse impact in either the racial or gender analyses during the interview stage. There was no evidence of adverse impact in the racial analysis during the appointment stage. There was however evidence of adverse impact in the gender analysis during the appointment stage. The Female Leadership Development Programme selection strategy revealed evidence of adverse impact in the racial analysis during the appointment stage. The Operator Services selection strategy revealed an adverse impact in both the racial and gender analyses during the testing stage. The issue of adverse impact is obviously controversial. However, data obtained from this process will provide for informative analysis.

- Description: There is considerable evidence that the strategic use of Information Systems can lead to a competitive advantage. There is however, a marked lack of understanding of the options available, as well as the smooth coordination of Information Systems strategy with Business strategy. This paper provides insight into the role of Information Systems and its link with business strategy. It focuses on Information Systems strategy options, and explores the criteria needed for successful Information Systems strategy and Business strategy alignment. The paper presents and examines the results of a study of strategic alignment at Volkswagen of South Africa. Data was obtained from business and Information Technology executives. The result of the study enables Volkswagen not only to benchmark themselves, but also provides direction to enable successful business/IT alignment. It identifies specific actions necessary to ensure that IT is being used to appropriately enable or drive the business strategy.
