M.Sc. (Geology) / Despite Chrissie Lake being South Africa's largest freshwater lake, the chemistry of this lake and the surrounding lakes and pans in the Mpumalanga Lake District has never been studied in detail. These closed systems show varying chemistry while being in very close proximity to one another, adding to the uniqueness of this area where pans, usually typical of arid regions, are found in a humid area. The factors affecting the water chemistry of these lakes needed to be identified and explained. In order to evaluate the water chemistry in this unique environment, water samples were taken at the end ofthe wet and dry seasons, in April and September 2007 respectively. The major pans were sampled, as were adjacent fountains or springs, indicative of the perched groundwater aquifers found in this area, as well as borehole water from the surrounding farms. Alkalinity was determined by manual titration upon returning from the field while pH and conductivity measurements were performed on site. Major cations and anions were analysed for using ICP-OES and Ion Chromatography respectively. Sediment samples were collected from the floor of each pan in the summer sampling and the mineralogy determined by X-ray diffraction (XRD). During September 2007 sampling, precipitates found on the floors and banks of the pans were also collected and analysed using XRD, to identify mineral species precipitating from solution. Initial results show pH values ranging from 7.0-10.5 for the lakes and pans and from 6.0-8.0 for the borehole water and springs. Values as low as 100 mglL Total Dissolved Solids (TDS) were measured for the pans, with maximum values set at 10 giL for the most saline of these bodies of water in the wet season and as much as 90glL for a pan almost completely dried out in the dry season. The water in the closed pan systems are dominated by Na-CI- HCO~ and have varying concentrations of major cations. The dilute spring waters have TDS values ranging from 20-200 mg/L, indicating the excellent quality of the groundwater, while some boreholes reach values of I 000 mg/L TDS showing possible linkage to pans or leaking of the pan water into the surrounding strata. To understand the main processes affecting the inorganic chemistry of the surface and shallow groundwater of this area, major ions were plotted against chloride. The latter behaves conservatively and can thus be used to monitor the behaviour of solutes in the pan waters. These plots illustrate that the dominant process in the evolution of the waters in the MLD is evaporative concentration. Removal of species through mineral precipitation is clearly seen; carbonate species...

M.A. / Kinship families have cared for children on a full-time basis for thousands of years, and for many years it has been standard practice for welfare agencies to consider the placement of children with kin whenever it becomes necessary to find an alternative way of caring for them. Many welfare experts believe that children will be better served if their care is provided by family members rather than strangers and yet, ironically, little scientific research has been done by welfare agencies and researchers to assess the value of kinship foster placement. Research focusing specifically on black foster parents is very scant. Generally, the decision about the placement of children in kinship homes has been based primarily on the professional observation of social workers as opposed to information derived from research findings. Despite the apparent growth in the use of kinship foster care and the concomitant suspicions about its advisability, children are still being placed in kinship homes. Kinship foster care placement is advocated most by welfare agencies, without the practice having been scientifically assessed. This deficiency has left the field with little information on which to base work with kinship foster families. The main purpose of this study was therefore to gain knowledge and to analyse the facts pertaining to kinship foster placement, and to draw a profile of kinship foster families in the urban residential area of Vosloorus. Quantative descriptive methods were used in this study. The main concern of the study was to collect data in such a way that it could be systematically processed and interpreted reliably. A descriptive design was chosen, as explanations can be tested by means of research questions. Eight research questions were formulated and put to the test. Facts were also established by studying literature reviewing case records, and interviewing foster parents as well as social workers. The results of this study suggest that we have not scientifically thought the purpose and goals of placing children with relatives through, but we have done so on the bases of certain assumptions, that is, we have assumed that relatives would be more willing to care and provide for the children of relatives than those of non-relatives. The study has provided information about kinship foster care and foster family care, focusing on the demographic characteristics of kinship foster parents, the services received by kinship foster parents, the manner in which kinship foster children are treated and the issue of visits by case workers. This study has provided insight and knowledge upon which agencies can base their selection of kinship foster parents. The findings have been discussed, and recommendations offered for policy, practice and future research.

M.A. (Psychology) / This study was motivated by the relative lack of research pertaining to the following aspects ofperfectionism: ~ The differences between the personality structure of high and low perfectionists. ~ The trend in available research in respect of perfectionism to regard the high perfectionist individual as maladapted and the low perfectionist individual as normal. ~ The possible association between parental styles and the development of perfectionist behavior in children. The literature describes perfectionism as a multi-dimensional construct. Perfectionism is perceived as consisting of both intra- and interdimensional aspects. The focus of the perfectionist can either be on the self (self-oriented perfectionism), on others (olher-oriented perfectionism) or on expectations from the outside world (socially prescribed perfectionism) (e.g. Hewitt &Flett, 1991a). According to a number of research studies the perfectionist is lnclned to suppress emotions (e.g. Smith, 1990) and harbour irrational thought patterns (e.g. Flett, Hewitt, Blankstein & Koledin, 1991). Interpersonal problems arise because the perfectionist, for example, isolates herself socially, criticizes others (Smith, 1990) and has an extreme need for control within interpersonal relationships (e.g. Mental Health Net, 1999). In spite of research regarding the association between perfectionism and certain personality traits there remains a dearth of findings concerning personality structure and perfectionism in women...

M.A. / Questions regarding the possible interrelations of work-related constructs of person-environment congruence, job satisfaction and job involvement were posed in this dissertation. These constructs were defined in terms of three separate theoretical frameworks, namely Holland's (1985b) vocational choice theory, the Theory of Work Adjustment (Lofquist & Dawis, 1984), and Kanungo's (1982b) conceptualisation of job involvement, respectively. In accordance with these theories, the Self-Directed Search questionnaire, the Minnesota Satisfaction Questionnaire, and the Job Involvement Questionnaire were used to operationalise these variables for the 114 psychologists and 44 optometrists who participated in the study. The person-environment congruence scores were computed by means of the Congruence Index (Brown & Gore, 1994). A secondary aim of the study was to evaluate the accuracy of environmental codes (one of the components of person-environment congruence) as have been provided by The South African Dictionary of Occupations (1987) for samples of psychologists and optometrists in the South African context. Different research designs were used to accommodate the diversity of the research objectives and hypotheses. A factorial research design was used to determine the potentiality of influences of person-environment congruence and job involvement on overall job satisfaction, intrinsic job satisfaction and extrinsic job satisfaction. Possible differences between the samples of psychologists and optometrists, and males and females were built into the general linear models encompassed by this design. Similarly, this design was used to determine whether job involvement is a function of personenvironment congruence, overall job satisfaction, intrinsic job satisfaction, extrinsic job satisfaction, gender and occupational group. Possible divergent effects of the samples and gender were further probed by means of generalised linear models (regression). Gender and sample-specific differences in terms of the variables of the study separately were examined through inferential statistics (t-tests). The possibility of a significant effect of job involvement on the relationship between person-environment congruence and job satisfaction assumed by Holland (1985b), was investigated by means of correlational analyses to conclude the examination of the relations among these variables. For the secondary aim of this study, the Environment Assessment Technique (Holland, 1985b) was used to calculate the respective environment codes of this sample of optometrists, and samples from four categories of registration of psychologists, namely clinical, counselling, educational and industrial psychologists, and then compared to the codes for these vocations listed in The South African Dictionary of Occupations (1987). The results of this study revealed significant effects of job involvement on overall job satisfaction and intrinsic job satisfaction, but nonsignificant effects of occupational group (or sample) and gender. Of the independent variables, only person-environment congruence had moderately significant effects on extrinsic job satisfaction. When job involvement served as dependent variable, only overall job satisfaction or intrinsic job satisfaction and the occupational group had any significant influence on it. The effect of the psychologist sample on job involvement was greater than that of the optometrist sample. No gender differences were found in terms of these linear models, or in terms of the variables of the study separately. Further findings revealed that job involvement does not have any significant effect on the hypothesised congruence-job satisfaction, congruence-intrinsic job satisfaction, or congruence-extrinsic job satisfaction relationships. When the environmental codes of the various samples were compared to the proposed Holland ISE (investigative-social-enterprising) environment code, vast discrepancies were found. A predominantly social environment code was obtained for clinical, counselling and educational psychologists, but an enterprising code for industrial psychologists. Although the optometrists obtained a predominately investigative code, their environment's subtypes could not be characterised as social and enterprising, but rather as enterprising and realistic. Suggestions were made that research employing sample-specific environmental codes in studies of person-environment congruence and its possible covariates is warranted. A need for empirical examinations of environmental codes of other vocational populations in South Africa was also identified. It was further recommended that the job involvement construct should be included in theories describing the antecedents, correlates and consequences of job satisfaction. This study was then evaluated in terms of criterion validity and external validity requirements, and the conclusion was drawn that within the limitations of the study, the research questions had been answered.

M.A. (Psychology) / The purpose of this study was to investigate and compare the career decisions of Black rural and urban high school students. Holland's (1985) structural-interactive career theory was decided upon as the main theoretical base. The reason for this decision is based on the simplicity of the theory as well as the fact that research into the applicability of the theory to Black South Africans is needed. Holland's theory (1985) is based on the assumption that all people and work environments can be characterised into one of six types; namely the Realistic, Investigative, Artistic, Social, Enterprising and Conventional. Each is dominated by certain likes and dislikes as well as certain attitudes and skills. Based on this theory is the Self-Directed Search (50S) which is used to indicate the resemblance of the person to each of the six types. The SNUG guide to career choice workbook (Scheepers, 1996) which is based on the 50S, was used in this study to investigate career choices. The nature of the study can be classified as empirical involving the use of quantitative data-collection methods. The research design and the paradigm of the study can be typified as quasi-experimental. The sample consisted of 144 grade 12 Black high school students. Two schools within the Northern Province region in Giyani and two schools from Gauteng province in Soweto participated. There are two main groups namely the rural (Giyani) and urban (Soweto) groups. The SNUG workbook included a biographical section together with a brief exploration of how an individual chooses his or her career.

M.A. / In this study it is assumed that psychological factors are playing an increasingly important role in the success of rugby teams in a professional era. One such a factor is that of group dynamics and specifically that of group cohesion. In this study, the use of another psychological construct, personality, in the improvement of cohesion is investigated. The personality profiles of the players in a particular team are analysed to determine the possible effects that the personalities of the players could have on the cohesion in the team. In this regard, the Jackson Personality Inventory —Revised is used to plot the personality profiles of all the players. Only scales of the inventory, that are relevant to cohesion, are being used. The relevancy of these particular scales are determined by the literary review of the cohesion construct, which includes the definition and essence of cohesion. Correlation studies would have to determine the true correlation between cohesion and the selected scales of the inventory. General tendencies in the team regarding the profiles and consequent influence on cohesion are discussed as well as the individual profiles of each one of the members of the team. In this regard, the possible influence that a particular player's personality profile could have on the cohesion in the team, is indicated and discussed. It is concluded that the use of personality profiles could be seen as a framework from which coaches and managers of rugbyteams could make use of in order to improve the cohesion in the team.

D.Cur. / Limited funds for the delivering of health and social services necessitate the cost-effective utilization of all categories of nursing personnel in old age homes. Professional nurses are being retrenched and supervision over weekends and after hours is being scaled down due to a lack of guidelines for the cost-effective utilization of nursing personnel in old age homes. A combined quantitative-qualitative approach had been applied in this empirical study to explore and describe the utilization of nursing personnel in old age homes. The goal of the study was to compile guidelines for the cost-effective utilization of nursing personnel in old age homes. Data collection and data analysis were conducted during three phases. A survey of the population of old age homes in South Africa was first conducted to determine the composition of the residents and nursing personnel in these old age homes and to explore the cost implications of the personnel composition. The contents of job descriptions of professional nurses working in old age homes were analysed on a computer by the researcher using NUDtIST software during the second phase of the study. The third phase consisted of conducting and analysing focus groups with professional nurses regarding. their expectations of their own duties, tasks and responsibilities and those of nursing auxiliaries and lay caregivers in old age homes. The three phases were conducted simultaneously and the results of the three phases were triangulated and subjected to a limited literature control. The results were verified during visits to nursing homes in the USA, Canada and the UK. A conceptual framework and guidelines for the cost-effective utilization of nursing personnel in old age homes were developed from the findings of this study. Respondents from the first phase of the study and experts verified the guidelines for being applicable, important, clear and accessible. The findings indicated that most of the residents of the old age homes are very old and are in need of 24 hours nursing/care due to their level of frailty. The nursing personnel budget forms a significant portion of the operating budget of the old age homes and managers are of the opinion that professional nurses are expensive but an essential component of the nursing personnel. The duties, tasks and responsibilities of professional nurses were identified as well as those which are shared with nursing auxiliaries and lay caregivers in old age homes. The conceptual framework which was established from the results of the study indicates that the goal, costeffective utilization of nursing personnel, is reached when quality care has been delivered within the constraints of the budget limitations. The process has been described as the compiling of guidelines for all categories of nursing personnel regarding clinical nursing, nursing management and nursing education as well as the handling of non nursing tasks while considering the personnel standards and job descriptions. The role players are the manager, all categories of nursing personnel, lay caregivers, family and volunteers which perform within the restrictions of the personnel composition and the appropriate code of conduct regulations. The context for the utilization of nursing personnel is the old age home where nursing/care giving is delivered on a continuum and the dynamics which influence the cost-effective utilization of nursing personnel include applicable legislation and policies of government departments and non government organizations.

M.Cur. / There is little information about the outcomes and safety of home births, although more and more women are starting to lean towards natural and active births. A home birth provides a more relaxed environment with familiar attendants and less medical intervention. No separation exists between mother and baby as well as other family members. Freedom of movement is promoted and the woman can eat and drink as she pleases. Unnecessary routine preparation for labour doesn't exist and privacy is respected. The purpose of this research was to explore and describe the outcomes of home births in Pretoria, attended by private midwifes, and to provide guidelines in relation with home births.
