  • Description: Demographically the aged are the fastest growing group both world-wide and in South Africa but despite this, psychologists have neglected psycho-geriatric research and its importance. In the past, old age has been studied by psychologists as a deviation from the norm of youth. The primary focus has been on the rate of cognitive decline, the process of social withdrawal and the etiology of dementia. Although these issues are of significant importance, the positive aspects of aging should also be considered; thereby challenging the stereotype that old age means disengagement, decline and degeneration. This study aimed to explore and describe the coping and life satisfaction of the retired elderly females in a residence for the aged. A quantitative exploratory descriptive research design was employed, making use of non-probability convenience sampling. The sample consisted of 40 retired females who have been living in a residence for the aged for at least 12 months. Further inclusion criterions were that the participants should have a relatively "sound/stable" neuropsychological status (i.e., they should not be suffering from any clinically diagnosed disorders, for example, dementia and/or Alzheimer's disease). The Coping Resources Inventory (CRI) was utilized to identify the coping resources used by the participants; the Orientation to Life Questionnaire (SOC-29) was utilised as a measure of the participants' sense of coherence; the Life Satisfaction in the Elderly Scale (LSES) was employed to measure the global life satisfaction of the participants, namely on the cognitive level. A biographical questionnaire collated important demographic and background information. The data was analysed through computing descriptive statistics. Following this a Pearson product-moment correlation coefficient was utilised to inter-correlate the total score of the SOC-29 and the total score of the LSES with the individual subscales of the CRI. The results of the present study indicated the following: the SOC-29 revealed a relatively high mean score for the current sample. Results of the CRI revealed relatively high mean scores for the total scale as well as the five different subscales. The highest scores were obtained for the Spiritual/Philosophical and Physical Resources Subscales, while the lowest score was obtained for the Cognitive Resource Subscale. Results from the LSES indicated relatively high mean scores for both the total and all eight subscales. The highest scores were obtained for the Mood and xii Social contacts Subscales, while the lowest scores were obtained for the Health and Finance Subscales. Significant positive correlation was evident between the total scores of the CRI, the SOC-29 and the LSES. With regard to the individual subscales of the CRI, the results indicated significant moderate relationships between the SOC- 29 total raw score, the LSES total raw score and the Cognitive, Social and Physical Subscales scores of the CRI. However, the SOC-29 and LSES total raw scores did not correlate with the Emotional and Spiritual/Philosophical subscales of the CRI.

  • Description: In South Africa the extraordinary high levels of violence and crime, escalating execution and killings of police officers, large number of murders, hijacking, robberies and shootings have created an unusually dangerous and stressful working environment for the members of the South African Police Services (SAPS). An overview of the literature on the nature of work in the SAPS indicates that these working conditions might have a detrimental effect on the coping resources and sense of coherence of police officers. This study aimed to explore and describe the coping resources and sense of coherence of male police officers in the SAPS. It employed a quantitative exploratory descriptive research design, making use of non-probability convenience sampling. The sample consisted of 70 male police officers who have been in the service of the SAPS for at least two years. All police officers that were included in the sample were also shift workers defined by the SAPS as police officers who work unsociable hours and who are likely to be exposed to violence, risks, danger, and traumatic situations. A further inclusion criterion was that the police officers must not be subjected to possible relocation or transfer as stipulated in Resolution 7/2002. The Coping Resources Inventory (CRI) was employed to identify the coping resources used by the participants and the Sense of Coherence Questionnaire (SOC- 29) was utilised as a measure of the participants’ sense of coherence. A biographical questionnaire collated important demographic and background information. The data was analysed by computing descriptive statistics. To examine the relationship between the sense of coherence and coping resources of the participants, a multiple correlation xv between the total score of the SOC-29 and the subscales of the CRI was conducted. Following this, a Pearson product-moment correlation coefficient was utilised to intercorrelate the total score of the SOC-29 and the individual subscales of the CRI. The results of the present study indicated the followings: The SOC-29 revealed relatively low scores for the current sample. Results on the CRI revealed low average scores for both the total and all five scales. The correlational analysis revealed a significant positive relationship between the two measures for the current sample.

  • Description: This is a qualitative case study of three Primary, schools in Port Elizabeth District.They are an ex -White, ex-Coloured and ex-Indian schools. These schools have become desegregated and are multicultural and multilingual. The medium of instruction in the schools is English. The study aims to show: Adaptations that teachers are making to make the curriculum accessible to children from diverse linguistic and cultural backgrounds; coping strategies that learners have needed to adapt when learning in a language that is not their mother tongue; attitudes of parents, teachers and pupils to the use of English and to the level at which the other home languages are offered as subjects. Another aim of the study is to document strategies and adaptations that teachers and learners have had to make in teaching and learning in multicultural and multilingual environments. Data was gathered through questionnaires, classroom observation, discussions with teachers, interviews with principals, parents and learners. The study concludes that two of the schools that were investigated have attempted to change school language policy. They have done this by introducing isiXhosa as one of the subjects in the curriculum. Contrary to the language policy which encourages maintenance of primary language, these learning contexts encourage the development of English to the detriment of isiXhosa. The issue that still needs to be addressed is the level at which isiXhosa primary language speakers are offered the language at school. This study further concludes that isiXhosa and Afrikaans speaking parents and learners in the English environments, value their primary languages for communicative purposes only in informal situations. English is valued as a language of access and for use as a language of learning and teaching. Finally, it is teachers in the Foundation Phase who seem to have needed to make a lot of adaptations and adjustments to accommodate non- native speakers of English in the classrooms.

  • Description: No coherent theory about the practice of South African intermediate phase school textbook evaluation has been forthcoming since the advent of a new South African school curriculum in 1998. This deficiency has had an adverse effect on the quality of intermediate phase school textbooks, as well as on the capacity to assess their value. This research project, therefore, had two aims. The first was to articulate a theory about the practice of textbook evaluation. The second was to develop a procedure for evaluating South African intermediate phase school textbooks in terms of the theory. The research method was underpinned by the interpretive research paradigm in terms of which relevant data were analysed and interpreted. The data emanated from a literature review, an analysis of the national Department of Education’s Revised National Curriculum Statement and its draft policy for the evaluation of learning support material, and two surveys. The first survey comprised a sample of intermediate phase teachers and the second a sample of intermediate phase textbook authors. Sufficient evidence was found to conclude that the capabilities of the authoring team, the authors’ rationale and their observance of the process of learning and instruction, the accessibility of the textbook, the availability of teacher support, meeting the requirements of the Revised National Curriculum Statement, and certain key notions about textbook evaluation play a role in articulating a theory about textbook evaluation in order to guide the process of determining the effectiveness of South African intermediate phase school textbooks. Based on the above-mentioned theory, this study proposes a procedure to assist teachers and textbook evaluators to assess the worth of South African intermediate phase school textbooks in a brief, systematic, thorough, rigorous, and practical manner.

  • Description: The implementation of a new curriculum has become a very relevant issue in South Africa with the implementation of Curriculum 2005 (C 2005) since 1998. The school principal plays a very important role at school level in the implementation of change in general and a new curriculum in particular. The aim of this study was to have a closer look at this role. It is a qualitative study executed in six schools in the Port Elizabeth area. It investigates the problems school principals experienced with the implementation of C 2005 with the objective of identifying guidelines for the role of the principal in the implementation of a new curriculum The most important findings include the importance of equipping the principal to provide guidance with the implementation of a new curriculum. This equipping refers to the principal’s knowledge of the new curriculum, the ability to employ various leadership styles, as well as the maintenance of a certain balance between supporting and putting pressure on the staff. Other findings refer to the importance of well-trained and prepared facilitators of workshops, as well as the role the Department of Education needs to play in the training and preparation of these facilitators. The ongoing support of schools in the implementation process also needs to be emphasized. The principal should play a key role with respect to this last role of the Department. The study also emphasizes the principal’s responsibility to bind the educators together in building a shared vision, so that their focus will remain on the curriculum implementation.

  • 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.

  • Description: This thesis addresses the topic of the education of the emotions in the context of a rapidly transforming South African society. It attempts to reconfigure the conceptual landscape in terms of which we think about rationality, social transformation and education, and contests the intellectual and instrumental prejudice in the currently dominant ways of thinking about education. It reclaims a sense of what it would be to think of education in terms of cultivating humanity, as a key to the profound transformation of the South African society. It argues that the emotions should be relocated in our conception of transformation and education, because without it, education will fail to assist South African society to transform into a society where most people are able to live improved quality lives. The thesis comprises three distinct parts. The first part consists of an account of a particular cognitive theory of the emotions, as developed by Martha Nussbaum in her book, Upheavals of thought. The Intelligence of Emotions (2001). This theory is then applied in Part 2 to examine the complexities of social transformation in South Africa at the more profound, personal level. This investigation is presented as a narrative and comprises the perspectives of the author, who is a white Afrikaner female, who grew up in South Africa in the heyday of Apartheid. In the final part, the concept of ‘education for transformation’ is discussed. It is argued that, in order for education to enhance the social transformation of South Africa, social transformation should be conceived according to a fundamental aspect of Rousseau’s political philosophy, namely that the ideal society comprises two reciprocally related spheres, the political and the personal sphere. Part 3 argues that ‘education for transformation’ should be conceived according to a conception of transformation, which acknowledges this double-layered texture. It further argues that ‘education for transformation’ should primarily be concerned with transformation at the personal level, since, according to Rousseau’s philosophy, this dimension is fundamental to ensuring the stability and legitimacy of the political order. However, built on the main insights of Part 2, this thesis also argues that personal transformation is only possible within a framework of rationality, which acknowledges the emotions as constitutive elements of rationality itself. Essentially, this thesis is about the conception of human being, which should be esteemed as the most fundamental and crucial element of successful social transformation.

  • Description: Traumatic brain injury (TBI) represents a significant and growing type of disability in South Africa. Coping with the impact of traumatic brain injury is one of the most difficult tasks that can confront a family, and family members experience a wide range of needs as the injured person progresses through rehabilitation. In South Africa, research on family needs following traumatic brain injury has thus far been neglected and rehabilitation resources are sadly lacking. For this reason it is necessary to accumulate knowledge about these families’ needs so as to assist with the planning of future rehabilitation programmes. The study aimed to explore and describe the needs of a sample of families with adult traumatic brain injury individuals in the Eastern Cape utilizing the Family Needs Questionnaire (FNQ). The research approach followed could be described as descriptive and exploratory in nature and was conducted within a quantitative framework. A biographical questionnaire and the FNQ were administered to a heterogeneous sample of 32 family members, including significant others and primary caregivers, of 16 adult traumatically brain-injured individuals, who sustained the TBI one to three years previously, and who underwent rehabilitation treatment at a private rehabilitation hospital in Port Elizabeth. A non-probability, purposive, and convenient sampling method was used. Descriptive statistics were computed to determine the importance and the perceived fulfillment of the needs. The results of the present study indicated that all 40 needs were endorsed by at least half the sample as being important to very important. Furthermore, 52.50% of the needs were endorsed by more than two-thirds of the sample as being important to very important. The needs were rank-ordered according to their importance ratings and the 10 mostly rated as important or very important were identified. These 10 needs were endorsed by between 84.38% and 93.75% of the family members as being important to very important. Six of the important or very important needs related to health information, two to professional support, one to community support, and one to emotional support. The relation between various participant, traumatically brain-injured individual and brain injury characteristics and the 10 important or very important needs, as well as the 10 needs more frequently rated as met were investigated and found to either have a limited or varied relationship. The 10 needs most often rated as met were endorsed by between 43.75% and 56.25% of the family members. Six of the met needs related to health information, two to community support, one to instrumental support, and one to treatment decisions. The highest unmet need was endorsed by 46.88% of the participants and related to the need to discuss their feelings with someone who has gone through the same experience. Based on the findings of the present study, further research on family needs following traumatic brain injury is suggested. It is also recommended that the Family Needs Questionnaire be used to evaluate existing rehabilitation programmes so as to make suggestions as to how to improve them. The results of this study suggested that family members would benefit from receiving educational information material, as well as referrals to professionals for advice and support.

  • Description: Currently, the approved anti-HIV drugs on the market only target the three HIV enzymes: reverse transcriptase, protease and more recently, integrase. Due to the limited nature of the current therapy, it is possible that a multi-drug resistant virus can emerge. The main concerns in developing countries however, are the expense and availability of the drugs and because of this, it is essential to investigate all alternatives. Traditional medicine offers many advantages as compared to allopathic treatment in so far as being relatively cheaper, accessible and it is broadly accepted in the population groups of the developing countries. Little is known though, of the exact efficacy and toxicity of these remedies so it is vital that these possible leads be investigated thoroughly. For the purpose of this study, two plants, Sutherlandia frutescens and Lobostemon trigonum were studied to ascertain their potential anti-HIV activity. Sutherlandia has received international attention as a possible cheap herbal remedy to improve the health of AIDS sufferers. Anecdotal evidence from health workers claim that HIV- infected patients on Sutherlandia treatment have shown improved CD4 counts, decreased viral loads and a general improvement in well-being. Extracts were prepared from dried leaves and flowers in methanol, ethanol, acetone, methylene dichloride or distilled water. Sulphated polysaccharides have been described extensively in literature with regards to their anti-HIV activity, so as a form of dereplication; an ethanol precipitation was performed on the aqueous extracts to remove sulphated polysaccharides. A toxicity study was performed on all crude extracts using uninfected peripheral mononuclear blood cells (PBMCs) isolated from whole blood. To measure anti-HIV activity, HIV-infected PBMCs were cultured with each of the crude extracts and cell viability measured using the tetrazolium salt, XTT. HIV-infected CEM-NKR-CCR5 cells were also used and supernatant from the viral studies was tested for the HIV antigen p24. xii Results varied greatly between assays but with the inclusion of a point-scale system to evaluate the extracts it was clear that overall the organic extracts of the Sutherlandia flowers, especially the acetone extract (SFA), showed great anti-HIV potential. SFA in every case decreased p24 levels and in the toxicity study did not decrease cell proliferation. With the HIV-infected PBMCs SFA actually helped improve cell proliferation despite the infection. To determine the specific anti- HIV activity, all crude extracts were tested for inhibition of HIV-I reverse transcriptase, the glycohydrolase enzymes: a-glucosidase, ß-glucosidase, ßglucuronidase, HIV-I integrase and HIV-II protease. No significant inhibition was seen with these experiments except for the HIV-I RT assay. The aqueous extract of the Lobostemon leaves produced an inhibitor of HIV-RT with a very low IC50 value of 0.049mg/ml. Some inhibitory effect was lost with the removal of the sulphated polysaccharides and the addition of BSA to the assay, but still 64% inhibition of the HIVRT remained, which confirmed that the inhibitor could be something novel, and not of the polysaccharide or tannin compounds.

  • Description: International research highlights conflicting results regarding factors that could play a role in the development of occupational aspirations and occupational gender stereotyping of primary school children. Some of the variables that have been identified are age, gender, ethnicity, socioeconomic status and societal influences. There has been some research emphasis on the career development of South Africans. However, studies that have been conducted have focused mainly on adolescents and adults. Furthermore, the majority of this research has focused on programme intervention and not on acquiring baseline information. There has been no research to date on the career development of South African Xhosa-speaking senior primary school children. The lack of career research on South African Xhosa-speaking children indicates the need for the present research. This study aims to describe and compare the occupational aspirations and occupational gender stereotyping (in terms of Holland’s occupational and status level typology) of male and female Xhosa-speaking senior primary school learners. The study also describes the possible gender stereotypical perceptions preadolescent children hold regarding certain occupations. A non-probability sample of 274 Xhosa-speaking children between the ages of 10 and 14 years was drawn from two primary schools in townships in the Nelson Mandela Metropole. An exploratory and descriptive research framework was utilised, with descriptive statistical procedures employed to summarise and report the data in a meaningful manner. The major findings of the present study indicate that Xhosa-speaking senior primary school children’s favourite occupational aspirations fit into Holland’s Investigative typology and high status level. Some gender differences were evident, with slightly more boys aspiring to Investigative occupations than girls. Both boys and girls demonstrated gender stereotypical perceptions regarding xiii which occupations were suitable for both genders, with boys more willing to accept girls into traditional male occupations than girls willing to accept boys into traditional female occupations. The results of the present study emphasise the need for further exploration of the occupational aspirations and occupational ge nder stereotyping of Xhosa-speaking senior primary school children. Future research needs to include other cultural and age groups in order to explore how personal and situational variables may differentially influence children’s occupational aspirations and occupational gender stereotyping.

  • Description: Zinc oxide (ZnO) is a II-VI semiconductor material that offers tremendous potential as a light emitter in the blue-to-UV range. It has a wurtzite structure, and a direct band gap that can be tuned from 3.0 to 4.0 eV by alloying with Cd or Mg, respectively. In this work, ZnO thin films were grown by metalorganic chemical vapor deposition (MOCVD) on n-Si 2 ° off (100), amorphous glass, n-GaAs (100), and c-plane sapphire substrates. Diethyl zinc (DEZn) and tert-butanol (TBOH) were chosen as precursors. For the first time, Second Harmonic Generation Imaging was applied to the mapping of ZnO epilayers. The images obtained highlighted the polycrystalline character of the thin films, and provided insight as to the growth mode of ZnO on Si. The influence of substrate temperature on the structural properties of the epilayers was investigated by X-ray diffraction and optical microscopy. Grain sizes as high as 54 nm were measured. The optimum temperature range for this system proved to be 450 – 500 °C. The influence of the VI:II ratio during growth on the optical properties of the epilayers was studied by UV-vis-near IR spectroscopy. The lowest Urbach tail E0 parameter was measured for material grown at a VI:II ratio of 18:1. The films’ free electron concentration was shown to decrease by over two orders of magnitude, from 1019 to 1017 cm-3, as the VI:II ratio increased from 10 to 60:1. This decrease in carrier concentration with rising VI:II ratio was paralleled to the surge at 12 K of a photoluminescence (PL) emission band characteristic of p-type ZnO. The band gap energies extracted from room temperature transmission spectra ranged between 3.35 and 3.38 eV, in agreement with the value of 3.35 eV measured by room temperature PL. Moreover, variable temperature PL spectra were recorded between 12 and 298 K on ZnO grown on Si. The 12 K spectrum was dominated by a donor-bound exciton (D°X) at 3.36 eV, while the 298 K scan displayed strong free exciton emission (FX) at 3.29 eV. The width of the D°X band proved to be as narrow as 7 meV. The intensity ratio between the room temperature near-band edge emission and the defect-related green band was as high as 28:1, highlighting the optical quality of the layers deposited in this work. The electrical properties of the thin films were studied by Hall measurements (van der Pauw configuration), and a maximum room temperature mobility of 11 cm2/Vs was recorded. Furthermore, a palladium (Pd) Schottky barrier diode on ZnO was fabricated. The barrier height and ideality factor were calculated from current–voltage measurements to be 0.83 eV and 1.6, respectively. The capacitance–voltage curve of the diode yielded a carrier concentration in the depletion region of 8·1017 cm-3. This study has shown that the optical and electrical properties of ZnO depend strongly on the growth conditions employed. A suitable choice of growth parameters can yield high quality ZnO that may be used for various devices. Keywords: Hall, MOCVD, optical spectroscopy, photoluminescence, Schottky barrier diode, SH Imaging, X-ray diffraction, ZnO.

  • Description: The proteasome is renowned for its high molecular weight, multisubunit and mulicatalytic nature. One of its many suggested roles is the degradation of myofibrillar proteins, and therefore it has been proposed to play a role in the meat tenderisation process. The aim of this study was therefore to isolate, purify and characterise the 20S proteasome from ostrich skeletal muscle, with a view to ultimately investigating its role in the tenderisation process of ostrich meat. The 20S proteasome was successfully isolated and purified from ostrich skeletal muscle using Toyopearl Super Q-650S, Sephacryl S-300, hydroxylapatite and Mono Q chromatographies. The intact molecule showed a molecular weight of 725 K and a pI of 6.67. The subunits showed a molecular weight range of 22.2-33.5 K and a pI range of 3-9. 2D-PAGE revealed at least 14 polypeptides. The amino acid composition of the intact enzyme and of each of the eight subunits separating on SDSPAGE, as well as the N-terminal sequences of five of the eight subunits, were determined. The trypsinlike (Tr-L), chymotrypsin-like (ChT-L), peptidylglutamyl peptide hydrolase (PGPH) and caseinolytic activities showed pH optima of 11, 9, 7-8 and 10.3, and temperature optima of 40, 60, 70 and 60oC, respectively. The pH stability range for all four activities was 5-12. The ChT-L and PGPH activities showed thermostabilities up to 60oC, whereas the Tr-L and caseinolytic activities were stable up to 40o C. The enzyme showed complex kinetics. It was inhibited by the peptide aldehyde Z-LLL-CHO and cysteine protease inhibitors. Cations had negligible effects on the enzyme, excepting for Ca2+ and Mg2+. Of the detergents tested, SDS had the most potent stimulatory effect, particularly on the PGPH and caseinolytic activities. The fatty acid studies showed that unsaturation enhanced the ChT-L and the caseinolytic activities, while it completely suppressed the Tr-L activity. Heating at 60oC for 1-2 min stimulated the caseinolytic and PGPH activities. The studies on the role of ostrich skeletal muscle 20S proteasome in ostrich meat tenderisation suggested a definite but minor role of this enzyme, based on the fact that it remained active throughout the 12 days of storage of ostrich M. iliofibularis meat at 4oC and that it participated in myofibril degradation of post-mortem muscle, but to a small degree. These results support the proposal that the proteasome comes into play after the calpains have initiated degradation. However, there was a lack of improvement in tenderness values and minimal myofibrillar degradation over the 12-day storage period of the ostrich M. iliofibularis meat, leading to the conclusion that the tenderisation of this meat was incomplete after 12 days.

  • Description: This project is concerned with the development of a search algorithm for a large archival database. The Port Elizabeth Genealogical Information System (PEGIS) contains a database consisting of almost 600000 individuals. The standard search algorithms are no longer sufficient to locate individuals in the database. A new algorithm was required that allows searches on any of the words or dates in the database, as well as a means to specify where in the desired record a word should occur. A ranking function of retrieved records was also required. A literature study on the field of Information Retrieval and on algorithms designed specifically for the PEGIS was done. These algorithms were adapted and hybridized to yield a search algorithm that allows for the boolean formulation of queries and the specification of the structure of search words in the desired records. The algorithm ranks retrieved records in assumed relevance to the user. The new algorithms were evaluated with regards to retrieval speed and accuracy and were found to be very effective.

  • Description: Africa as no exception. It is generally accepted that women constitute the vast majority of sexual harassment victims. Sexual harassment is therefore one of the major barriers to women’s equality as it is a significant obstacle to women’s entrance into many sectors of the labour market. The Constitution now provides that no person may unfairly discriminate against anyone on grounds of, inter alia, sex and gender. The Employment Equity Act now provides that harassment is a form of unfair discrimination. It has been said that harassment is discriminatory because it raises an arbitrary barrier to the full and equal enjoyment of a person’s rights in the workplace. Much can be learned from the law of the United States and that country’s struggle to fit harassment under its discrimination laws. The Code of Good Practice on the Handling of Sexual Harassment Cases attempts to eliminate sexual harassment in the workplace by providing procedures that will enable employers to deal with occurrences of sexual harassment and to implement preventative measures. The Code also encourages employers to develop and implement policies on sexual harassment that will serve as a guideline for the conduct of all employees. Although the Code has been subject to some criticism, particularly regarding the test for sexual harassment, it remains a valuable guide to both employers and employees alike. The appropriate test for sexual harassment as a form of unfair discrimination has given rise to debate. Both the subjective test and the objective test for sexual harassment present problems. Some authors recommend a compromise between these two tests in the form of the “reasonable victim” test. The Employment Equity Act makes the employer liable for the prohibited acts of the employee in certain circumstances. The Act, however, places certain responsibilities on the employer and the employee-victim before the employer will be held liable for sexual harassment committed by an employee. Sexual harassment committed by an employee constitutes misconduct and can be a dismissible offence. An employer may also be held to have constructively dismissed an employee, if the employer was aware of the sexual harassment and failed to control such behaviour, and the employee is forced to resign. The test for determining the appropriateness of the sanction of dismissal for sexual harassment is whether or not the employee’s misconduct is serious and of such gravity that it makes a continued employment relationship intolerable. However, for such a dismissal to be fair it must be both substantively fair and procedurally fair.

  • Description: In the employment context employers may view certain conduct/behaviour committed by an employee or a group of employees to be repugnant and unacceptable resulting in the disciplinary action that may lead to a dismissal sanction taken against such employee or employees. Even though the employer has a right to discipline the employees for a contravention of a rule or a policy and even dismiss the employee/s involved, such a disciplinary action and dismissal must be based on a certain procedure where the principle of fairness must be adhered to. The Labour Relations Act 66 of 1995 (“the Act”) and Schedule 8 of the Code of Good Practice deals with the aspects of dismissals related to conduct and capacity, however, each case is unique, it has to be approached on its own merits. Schedule 8(3) states that, “formal procedures in disciplinary measures do not have to be invoked every time a rule is broken or a standard is not met”. It is therefore necessary that there should be a disciplinary code which guides the workers and the employers, it must be clear and be understood by all the parties. The disciplinary code of conduct serves as the foundation of good discipline because everybody knows the consequences of his/her contravention of those guidelines enumerated in the Code of Conduct. The Code of Good Practice under Schedule 8(3), states that “while employees should be protected from arbitrary action, employers are entitled to satisfactory conduct and work performance from their employees”, so a very good relationship between the two parties is most important if there is to be stability and industrial peace in the workplace.

  • Description: Adolescents in a children’s home are exposed to unique experiences from an early age. These adolescents develop in a system with early deprivation experiences, which may result in developmental and adjustment problems that impact on several spheres of their lives, including their career development. Given the lack of South African career research on adolescents, the present study aimed to explore and describe the career development of adolescents in a children’s home. Specifically, this exploration takes the perspective of the systems theory framework of career development which is comprised of three interrelated systems, namely the individual, social, and the environmental/societal systems. The research approach was exploratory and descriptive in nature and was conducted both within a qualitative and quantitative framework. A workbook titled My System of Career Influences (McMahon, Patton, & Watson, 2003a), was used to collect the data. A non-probability, purposive sampling technique was employed to obtain the sample which consisted of 16 English-speaking adolescents, aged between 13 and17 years. Age, gender and culture were not considered in this study. The qualitative data was subjected to content analysis to identify themes, while frequency counts were used for the quantitative data. The results indicate that the present sample of adolescents is presently in the process of exploring and crystallizing their career choice, therefore fitting well within Super’s (1990) theoretical career stage of Exploration. The majority of the adolescents indicated that their present career situation involves making choices regarding schools, subjects, and participation in activities. Quantitative findings indicate that all influences within the three interrelated career systems have an influence on the career development of adolescents in a children’s home. Based on frequency counts, individual system influences such as personality, health, interests and abilities were identified as prominent influences. Within the social system, prominent xi influences included parents, friends, teachers and reading. Within the environmental/societal system, influences such as financial support, location of universities, availability of jobs, and opportunities to work overseas were identified as prominent influences. In addition, adolescents were able to reflect on their personalized diagram of system influences and thus to examine the inter-relatedness of the three systems. The present study highlights the applicability of both the systems theory framework and the My Systems of Career Influences measure in exploring and describing the career development of adolescents in the unique contexts within which they live. Limitations and recommendations for future research based on the present findings are suggested.

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 southeastern coast of South Africa is deemed unpolluted and with the exception of a few localized areas, is believed to be pristine. This study aimed to (1) assess the concentration of metals in the water and sharks (Squalus megalops, Mustelus mustelus) from different sites along the southeastern coast, (2) determine the effects that metals have on each other and investigate the accumulation and storage of metals in different shark tissues, (3) determine the effects of length and sex on metal concentration and the presence of metallothioneins in the liver. Metal concentrations in water from seven sites along the southeastern coast revealed concentrations below the detection limit of the extraction method, except for iron at St. Francis Bay which was below the recommended levels as supplied by DWAF. Met al concentrations in S. megalops from the seven sites revealed significantly elevated levels in individuals from Algoa and St. Francis Bay when compared to the other 5 sites. This was observed for all metals except manganese, which had a higher concentration at Cape Agulhas. After comparing the metal levels in muscle tissue (S. megalops) with data from the Department of Health it was concluded that the sharks caught at Algoa and St. Francis Bay were unsuited for human consumption. Liver and vertebral tissues from both S. megalops and M. mustelus were deemed unsuited for human consumption but further research should be conducted especially on vertebral metal concentrations. Comparing the metal concentration in different tissue types of S. megalops and M. mustelus significant difference were observed and attributed to differences in the maturity (thus age) of the two species. Significant differences in the metal concentration of males and females for both the species were observed. A higher number of differences were however observed in M. mustelus than in S. megalops, most probably due to the differences in maturity. Length and weight vs. metal concentration regressions in the males and females of both species revealed more negative than positive trends. This was found to be in accordance with other studies from around the world. Using the life stages of S. megalops, significant differences in the average concentration of metals were observed between the life stages, with embryos usually having the highest concentration. The metal concentration series determined for S. megalops were similar to that which have been reported in the literature in that iron and zinc occupied the highest concentration positions while cadmium, copper and manganese occupied the last three. The spleen usually had the highest metal concentration except for aluminium in skin and arsenic in muscle tissue. Pearson correlation revealed significant negative correlations between cadmium and the mentioned metals suggesting that cadmium replaces essential metals such as manganese, iron and copper as. Negative correlations between essential metals were observed most probably due to the competition for binding positions on ligands. Positive correlations were observed between metals in sp ecific tissue types and may be indicative of synergistic effects, e.g. aluminium may result in the accumulation of other metals such as cadmium. Positive and negative correlations between a specific metal and different tissue types have also been observed and it appears that there are movement of metals between tissue types. Positive correlation for essential metals between yolk and other tissue have been observed, although no correlations for non-essential metals were observed. This could potentially indicate a mechanism that prevents the accumulation of nonessential metals in embryos. Though no metallothioneins were isolated form the liver, the presence of cadmium in other proteins indicate that that cadmium is substituted for essential metals, and as this may result in deleterious physiological effects, further studies should be conducted. In conclusion it can be said that although some of the results were expected there are still quite a few unanswered question and further studies should be conducted.

  • Description: Our employment law which originates from the common principles has in recent years undergone significant changes. Under common law the employers and employees capacity to regulate their relationship has always been limited. The recommendations of the Wiehahn Commission introduced amendments to the Labour Relations Act of 1956. The introduction of the unfair labour practice concept and the establishment of the Industrial Court was a direct consequence of the recommendation of the Wiehahn Commission. The Industrial Court together with the higher courts developed new principles regarding unfair labour practices. In the process, a wealth of unfair labour practice jurisprudence was developed by these courts. However, the unfair labour practice definition did not include dismissals. The coming into power of the democratic government played an important role in transforming our labour law system. After the Labour Relations Act 66 of 1995 was implemented on 11 November 1996, the old Labour Relations Act of 1956 was repealed. The law on retrenchment forms an integral part of our law of dismissals. The South African labour market has in the past years been characterised by restructuring and consequently retrenchment of employees. In most cases, employer’s decisions to retrench were challenged by the employees and unions in our courts. Section 189 of the Labour Relations Act of 1995 stipulates procedures to be followed by an employer when contemplating dismissal of one or more employees for reasons based on operational requirements. The employer does not only have to follow the procedures set out in section 189 to render dismissals for operational reasons fair, but there must also be a valid reason to dismiss. The courts have always not been willing to second-guess the employer’s decision to retrench provided that the decision is made in good faith. Whilst section 189 deals with small-scale retrenchments, section 189A applies to large-scale retrenchments. These are employers who employ more than 50 employees and who contemplate retrenchment of more than the number of employees provided for in section 189(1)(a) or (b). Section 189A also introduced a facilitation process to be conducted in terms of regulations made by the Minister of Labour. The amendments to section 189 should be seen as an attempt to tighten the procedural aspect of retrenchments. The new law on retrenchments is a product of tough negotiations between the social partners at NEDLAC in which compromises were reached. There are still certain areas of concern to both labour and business. In those areas in which uncertainty still exists, the courts will be required to provide some guidance.
