- Description: While career development is viewed as a lifelong process, there are numerous limitations regarding existing career theories and research pertaining to the adolescent population. Further, insufficient longitudinal research represents one of the major obstacles for a more holistic understanding of career development across the lifespan. Thus, the present longitudinal project of which the current study forms a part was initiated to address the lack of research and theory concerning adolescent career development. The larger longitudinal project intended to make information available regarding the occupational aspirations and perceptions of a sample of South African children and adolescents, from early childhood into their adolescent years. The current study investigates the occupational aspiration development of 15 to 16 year old South African adolescents. It is argued that the South African knowledge base on career development behaviour still requires extensive development, especially with regards to adolescent career development. The current longitudinal study aimed to explore and describe possible developments and changes over a two year period in the interest typology, occupational status level and occupational gender stereotypes of the 43 adolescents. Additionally, the study aimed to explore and describe the adolescents' reflections on their own occupational aspiration development. The findings of this study will provide necessary baseline information on the development of South African adolescents' occupational aspirations and will offer valuable recommendations for the future development of adolescent career education programmes. Adolescent and career development theories were used to provide a context for the current study. Semi-structured interviews and biographical questionnaires were utilized to record verbal data which was transposed into nominal data for analysis. Thus, the current study was quantitative in nature. The semi-structured interview comprised four general aspects that included: the adolescents' occupational aspirations, the number of occupations they knew about, how much they knew about the expressed occupations, and the extent to which they held gender stereotypes concerning fourteen different occupations. The data gained was coded according to Holland's (1985) classification system of interest typologies. Also, the adolescents' occupational aspirations were coded according to their status levels. The coded data was subsequently analysed using both descriptive statistics in the form of frequency counts and percentages as well as inferential statistics in the form of chi-square analysis. Content analysis was also conducted on the adolescents' reflections on their own career development as a means to extract themes. The results indicated that adolescence was an important phase of career development and the findings supported adolescent and career development theories. The results of the study also indicated that the majority of adolescents aspired to Investigative type occupations across both years of the study and most adolescents consistently aspired to high status occupations. In addition, adolescents do not appear to gender stereotype in terms of occupations. Lastly, it was found that most adolescents could reflect on their career development, predominantly attributing changes in their occupational aspirations to changes in their interests. The present study has made available important information regarding the occupational aspiration development of a group of South African adolescents, which can be utilized in further research and as a foundation on which to develop career education programmes.

- Description: Psychobiographies use psychological theory as a paradigm within which to re-awaken an individual’s life story. The psychobiographical approach historically tended to be neglected within the South African context. The aim of the current study was to explore and describe the life of Ralph John Rabie through the use of psychobiography. Ralph John Rabie (1960 – 2002) was a South African Afrikaans singer-songwriter, journalist and playwright, also known as Johannes Kerkorrel. He challenged the cultural system and the government and was arguably the most prominent member of the Alternative Afrikaans Movement until his suicide on 12 November 2002. To some he betrayed the identity of post-apartheid Afrikanerdom and to others he became an icon in the homosexual community. No existing literature to date has adopted a psychological stance on this controversial South African figure. His own writings and published material by others were utilized to illuminate his life and its many dimensions. Richard C. Schwartz’s Internal Family Systems Model (1995) was used to analyze the multiplicity and inner workings of Rabie’s personality. The influence of external systems is also discussed. The data collection and analysis were conducted according to Yin’s (1994) analytic generalization, which consists of using theoretical guidelines as a framework to select relevant data and develop a matrix as a descriptive framework for organizing and integrating the data. Alexander’s (1988) nine proposed guidelines assisted in the process of data analysis, together with the Internal Family Systems Model (1995). The findings of the study indicate that subpersonalities in different roles could be identified in Rabie’s life as described by Schwartz (1995). The different subpersonalities interacted with each other and assumed roles to protect Rabie. The findings of the study also indicated that these subpersonalities used stories to obtain power and influence within Rabie’s personality structure. The subpersonalities were successful in making Rabie influential and famous within the Afrikaans music industry and they helped Rabie change rigid Afrikaans cultural beliefs that were present within the Apartheid system. The findings further indicate how important it is for subpersonalities to work together and how a fragmented system is difficult to contain.

- Description: While the value of psychobiographical research continues to be debated, interest in this area is growing on an international basis. From the ever increasing number of studies being conducted in connection with academic institutions in South Africa, the vitality and worthiness of studying lives lived in conjunction with the applicability of psychological theories is showing itself to be an exciting world in which to participate. This particular research study aimed to explore and describe the developmental life stages of Paul Jackson Pollock. Pollock was, and continues to be, a controversial figure in the art world as there is much debate over the artistic merit of his paintings. Unconventional in all that he did, Pollock challenged the art world by moving beyond paintbrush and easel to throwing paint across canvasses laid out on the floor. Around these emerging artworks he would move in a staccato dance, mesmerising those present by the way he made art immediate using his entire body to create the abstract image. Pollock is credited with being the pioneer of abstract expressionism in the United States, and to date his paintings are credited as being among the most expensive ever sold. He struggled with alcoholism and emotional instability throughout his teens and adult life. His alcoholism eventually caused his death at the age of 44 when, while heavily intoxicated, he drove his car into a tree a few metres from his home. No known literature has adopted an exclusively psychological stance when studying the life of this individual. The progression of Pollock’s lifespan development was filtered through Erikson’s (1950) theory of psychosocial stages. Erikson’s (1950) theory takes a holistic, biopsychosocial approach to human development, with an emphasis on ego development. Data was collected from both primary and secondary sources to enhance internal validity, and the data was then analysed according to Miles and Huberman’s 1994 general approach, taking Alexander’s (1990) nine identifiers of salience into necessary consideration. Using this framework, it was found that Jackson Pollock’s development coincides with Erikson’s theoretical psychosocial stage constructs, lending weight to Erikson’s theory. While Pollock’s life paralleled Erikson’s (1950) theory in many ways, the theory failed to provide enough definition with regards to constructs and intrapsychic processes. However, this study has also shown that there is great value and relevance to be found in Erikson’s (1950) theory, even though it was developed over fifty years ago.

- Description: The extensive amount of research conducted internationally in the field of John Bowlby's attachment theory indicates that an insecure attachment between a child and the primary caregiver has a detrimental effect on both social and emotional development in childhood, as well as having a profound effect on psychological development and functioning in adulthood. The present study aimed to explore and describe the therapeutic process of a nine year old with an insecure attachment style within a therapeutic framework, namely Theraplay. The therapeutic process was embedded within Ann Jernberg's Theraplay framework and the case was further contextualized within Bowlby's attachment theory. The case study method was utilized with a purposive sampling technique employed to select the participant. Irving Alexander's content-analytic framework in conjunction with Guba's model of trustworthiness was employed for data analysis. Two needs emerged during the therapeutic process namely the need for nurturance and affection as well as the need for power, control and safety.

- Description: Children are placed in a children’s home when a Presiding Officer finds them to be in need of care and when there is no viable community placement alternative. The body of literature on children’s homes focuses primarily on the negative effects and outcomes of such statutory placement. The assertion that children who grew up in children’s homes will continue to use the services of welfare organisations in adulthood, is supported by the researcher’s observation as a practicing social worker. This, and the study of available literature, resulted in this qualitative, exploratory-descriptive and contextual research study with the following goal: to enhance the understanding of how intervention programmes at children’s homes can contribute to adult adjustment and independent functioning of those children in their care. A purposive sampling method was used to identify ten participants who had spent at least 2 years in a children’s home and who had been discharged from the children’s home at least 5 years ago (to the date of data collection). The sample was drawn from clients at non governmental social welfare agencies who fitted the sampling criteria. The data was collected via semi-structured interviews using an interview guide, which were recorded, transcribed and then analysed using a thematic content analysis approach. The results of the study may be used to develop and implement meaningful intervention strategies for individuals placed in children’s homes.

- Description: In order to continue their contribution to the profession of psychology in South Africa the selection committees of psychology departments of higher education institutions are faced with the difficult task of selecting the most suitable candidates to fill their Clinical, Counselling, Educational and Industrial Psychology masters coursework programmes. Selection committees have traditionally made use of several admission criteria and procedures ranging from academic performance to personality assessment to a combination of methods. Admission criteria vary greatly across Higher Education Institutions. The selection committee at the selected participating institution of higher education takes into account the prospective students' academic performance, relevant work or practical experience, research experience, active participation in the classroom, active involvement outside of the classroom (participation in and engagement with community activities), and personality. Currently the institution of higher education that provided the sample for the current study employs the NEO PI-R as well as the MMPI-2 to assess masters applicants’ personality traits. A study by Britz (1994) recommended that the MBTI® be included in the assessment battery for psychology masters students. The primary aim of the proposed study is to identify, explore and describe the personality preferences of a group of prospective psychology masters applicants and a group of successfully selected psychology masters students at a South African Higher Education Institution utilising the Myers-Briggs Type Indicator® (MBTI®). The study was exploratory descriptive in nature and was based on the quantitative research approach. Non-probability convenience sampling and the survey method was utilised to identify and approach prospective participants. Participants were requested to complete the MBTI® questionnaire. The MBTI® protocols were hand-scored and the findings analysed utilising frequency distributions and inferential statistics, that is, means and standard deviations. The MBTI® was found to be valid and reliable in a variety of populations and contexts. xi Results indicated that the ISTJ (15 percent), INTP (15 percent) and ESFJ (15 percent) personality types were the three most common personality types amongst participants from the group of prospective psychology masters applicants. The ENFP (13 percent), INTP (13 percent) and ISFJ (13 percent) personality types were the three most common personality types amongst participants from the group of successfully selected masters students. The majority (14 percent) of participants from the total sample displayed a preference for the INTP personality type. An examination of the dichotomous personality types of the participants revealed that the majority of participants preferred the Extraversion attitude, Sensing and Thinking functions, and Judgement attitude.

- Description: In the last decades, there has been an escalating consumption of antibiotics with the number of antibiotic prescriptions increasing worldwide. Overuse or inappropriate use of antibiotics has resulted in a major increase in the development of multi-drug resistant pathogens. Antimicrobial resistance is one of the world’s most serious public health problems with great implication in terms of morbidity, mortality, and costs. To date, there has been no formal antibiotic use study conducted in the West Wollega zone of Ethiopia to assess antibiotic utilization. The objective of this study was to determine the pattern of antibiotic use in two hospitals in the West Wollega zone of Ethiopia, namely Gimbie Adventist Hospital and Nedjo Hospitals, using drug utilization metrics and the costs associated. In addition it was to assess the correlation between diagnosed infectious diseases and antibiotic prescriptions. This study was a cross-sectional, retrospective, descriptive review of antibiotic usage in the two hospitals in the year 2007. Prescriptions dispensed in the first month of each quarter of 2007 were reviewed. The number of prescriptions screened, antibiotic courses started, antibiotic days by specific agent and overall, the cost of individual and all antibiotics, the number and type of infectious diseases diagnosed were collected from which core drug use indicators were calculated. The correlation between infectious disease diagnosed and the antibiotic days prescribed were analyzed. A total of 18568 antibiotic and non-antibiotic prescriptions were reviewed retrospectively in the four months of the study period, 47 percent of which contained at least one antibiotic. The average number of antibiotics per prescription was 1.33 and 1.09 whilst the percentage of injectable antibiotics prescribed was 83.2 percent and 3.76 percent to outpatients and inpatients respectively. Antibiotics prescribed from the Essential Drug List (EDL) and List of Drugs for District Hospital (LDDH) were 63.0 percent, 74.8 percent, and 90.8 percent and 76.1 percent for outpatients and inpatients respectively. 98.6 percent of outpatient and 97.0 percent inpatient prescribed antibiotics were actually dispensed. Penicillins and quinolones were the most prescribed antibiotics in both inpatient and outpatient departments constituting 43.46 percent and 24.08 percent respectively. The antibiotic utilization ratio, incidence of outpatient antibiotic use, incidence of inpatient antibiotic use, the number of Defined Daily Doses (DDD)/1000inhabitants/year and DDD/100 Occupied Bed Days (OBD) for the zone was 0.16, 17.25, 23.56, 158.61, and 70 respectively. Antibiotic cost constituted 33.7 percent of all expenditure on drug, cost of antibiotic per patient care day and cost per antibiotic day was 3.84 Ethiopian Birr (ETB) ($0.40) and 6.29 ETB ($0.66) respectively. The correlation between infectious diseases diagnosed and antibiotic prescription shows significant variation. At outpatient departments alone an average number of antibiotic courses started was 2.7 at Gimbie Adventist Hospital and 7.6 for Nedjo Hospital. When overall antibiotic days prescribed and required was compared in both hospitals, there were 2.4 and 5 times more antibiotic days prescribed than were required for Gimbie and Nedjo Hospitals respectively. This suggests that the overuse of antibiotic is worse in the government hospital (Nedjo Hospital) than in the mission hospital (Gimbie Adventist Hospital). This study suggested that there was overuse of antibiotics in the West Wollega hospitals although further investigation is needed to identify its underlying causes and nature. It is recommended that the health personnel, the hospital management, the zonal and regional Health Bureau, the regulatory bodies and Non-Governmental Organizations (NGOs) work hand-in-hand to promote the rational use of antibiotics in this region so that the consequences and financial cost of antimicrobial resistance can be prevented.

Antimicrobial resistance is one of the world’s most serious public health problems with great implication in terms of morbidity, mortality, and costs. To date, there has been no formal antibiotic use study conducted in the West Wollega zone of Ethiopia to assess antibiotic utilization. The objective of this study was to determine the pattern of antibiotic use in two hospitals in the West Wollega zone of Ethiopia, namely Gimbie Adventist Hospital and Nedjo Hospitals, using drug utilization metrics and the costs associated. In addition it was to assess the correlation between diagnosed infectious diseases and antibiotic prescriptions. This study was a cross-sectional, retrospective, descriptive review of antibiotic usage in the two hospitals in the year 2007. Prescriptions dispensed in the first month of each quarter of 2007 were reviewed. The number of prescriptions screened, antibiotic courses started, antibiotic days by specific agent and overall, the cost of individual and all antibiotics, the number and type of infectious diseases diagnosed were collected from which core drug use indicators were calculated. The correlation between infectious disease diagnosed and the antibiotic days prescribed were analyzed. A total of 18568 antibiotic and non-antibiotic prescriptions were reviewed retrospectively in the four months of the study period, 47 percent of which contained at least one antibiotic. The average number of antibiotics per prescription was 1.33 and 1.09 whilst the percentage of injectable antibiotics prescribed was 83.2 percent and 3.76 percent to outpatients and inpatients respectively. Antibiotics prescribed from the Essential Drug List (EDL) and List of Drugs for District Hospital (LDDH) were 63.0 percent, 74.8 percent, and 90.8 percent and 76.1 percent for outpatients and inpatients respectively. 98.6 percent of outpatient and 97.0 percent inpatient prescribed antibiotics were actually dispensed. Penicillins and quinolones were the most prescribed antibiotics in both inpatient and outpatient departments constituting 43.46 percent and 24.08 percent respectively. The antibiotic utilization ratio, incidence of outpatient antibiotic use, incidence of inpatient antibiotic use, the number of Defined Daily Doses (DDD)/1000inhabitants/year and DDD/100 Occupied Bed Days (OBD) for the zone was 0.16, 17.25, 23.56, 158.61, and 70 respectively. Antibiotic cost constituted 33.7 percent of all expenditure on drug, cost of antibiotic per patient care day and cost per antibiotic day was 3.84 Ethiopian Birr (ETB) ($0.40) and 6.29 ETB ($0.66) respectively. The correlation between infectious diseases diagnosed and antibiotic prescription shows significant variation. At outpatient departments alone an average number of antibiotic courses started was 2.7 at Gimbie Adventist Hospital and 7.6 for Nedjo Hospital. When overall antibiotic days prescribed and required was compared in both hospitals, there were 2.4 and 5 times more antibiotic days prescribed than were required for Gimbie and Nedjo Hospitals respectively. This suggests that the overuse of antibiotic is worse in the government hospital (Nedjo Hospital) than in the mission hospital (Gimbie Adventist Hospital). This study suggested that there was overuse of antibiotics in the West Wollega hospitals although further investigation is needed to identify its underlying causes and nature. It is recommended that the health personnel, the hospital management, the zonal and regional Health Bureau, the regulatory bodies and Non-Governmental Organizations (NGOs) work hand-in-hand to promote the rational use of antibiotics in this region so that the consequences and financial cost of antimicrobial resistance can be prevented.

- Description: Bacterial resistance to antibiotics has been a great problem for many years. The degree of resistance and the speed with which resistance develops varies with different organisms and different drugs. Enzymes called β-lactamases are produced by bacteria and are one mechanism in which bacteria develop antimicrobial resistance. Gram-negative bacteria producing enzymes called ESBLs because of their wide substrate range are of a particular concern in nosocomial infections. In many countries people still use traditional medicine derived from plants as an alternative to the Western medicine due to increased cost of Western medicine and microbial resistance of antibiotic treatments. Biologically active compounds isolated from plants species are used in herbal medicine. Because of the high prevalence of the ESBLs and their increasing resistance to the antibiotics, this research study was done to test the antimicrobial activities of selected medicinal plants of the Eastern Cape; G. incanum, D. angustifolia and E. autumnalis which were traditionally used to treat various infections. The in vitro antimicrobial activity of three different extracts (acetone, methanol & distilled water) and the traditional preparations of the three plants were tested against the selected strains of ESBL-producing bacteria, non β-lactamase producers and the different fungal species. The extracts were screened against 26 Gram-positive bacterial strains, 53 Gram-negative bacterial strains and 15 fungal strains. The Gram-positive bacteria included strains from S. aureus, B. cereus and E. faecalis. The Gram-negative bacteria included strains from E. ii coli, E. cloacae, K. pneumoniae, P. aeruginosa and Acinetobacter spp. The fungal strains included 9 strains of Candida albicans and a single strain of each of the following opportunistic fungi, Mucor sp, Geotrichium sp, Penicillium sp, Fusarium sp and Rhizopus sp. The agar dilution assay was used for the antimicrobial screening of the plants extracts and for the determination of the MICs. The Ames test was performed for the determination of probable carcinogenicity of the extracts of G. incanum and D. angustifolia. The distilled water extracts followed by acetone extracts of the plants revealed the highest antimicrobial activity against the different microbial strains. The extracts of G. incanum followed by the extracts of D. angustifolia inhibited the highest number of microbial strains. The extracts of E. autumnalis did not show any antimicrobial activity against all the pathogens in this study. More of the Gram-positive bacteria were inhibited by the plant extracts. The lowest MIC was obtained with Gram-positive bacteria. The bacterial strains of E. faecalis and P. aeruginosa were not inhibited by any of the plants extracts in the agar dilution assay yet Acinetobacter species which are MDR were inhibited by the distilled water and methanol extracts of G. incanum. A single strain of Mucor sp was the only spore forming fungi that was inhibited by the distilled water extracts of G. incanum. None of the plants extracts showed any mutagenic effects on the TA100 S. typhimurium strains incorporated on the Ames test. Apart from revealing of new antimicrobial agents that may be used against resistant organisms, the proper use of antimicrobial agents should be recommended. The study has highlighted a need for further investigations on the properties of the medicinal plants used in this study.

- Description: In South Africa the pharmacy profession has experienced a number of changes around the turn of the century such as the introduction of the National Drug Policy (NDP), pharmacy ownership and price regulation. With this the role and earnings of the pharmacy profession, as well as to what extent the pharmacist adds value to the profession and society, are being questioned. Community pharmacists are thus faced with the challenge to prove that the value that they add to society is meaningful. Therefore, the aim of the study was to document community pharmacy availability and activities in South Africa and based on this to quantify the perceived value that the community pharmacist adds to society through the delivery of pharmaceutical services and pharmaceutical care. In order to determine the pharmacist’s true value added two surveys were conducted in 2006; an original pharmacist survey and a general public survey. The results obtained were verified by a follow–up pharmacist survey in 2009 to confirm or reject the results obtained in the original survey. The study was representative of both the community pharmacies and the general public in South Africa and was primarily quantitative in design and analysis. More than half of the responding pharmacies (63.16%) were open seven days a week. The average hours of service per day ranged from 10 hours (Monday to Friday) through to 6.45 hours on Saturdays and 3 hours on Sundays. Pharmacists continuously upgraded their professional knowledge. More than three quarters of pharmacies had the necessary equipment available to perform the services investigated in the study. The general public was not aware of all the services provided by pharmacists and as a result, depending on the service, many people did not make use of these services. The general public that made use of services delivered by community pharmacies mainly perceived the services delivered to be of good quality. The main barrier to practicing pharmaceutical care was indicated by pharmacists as not receiving payment for the advice given followed by pharmaceutical care being time consuming, and that there was not enough time to talk to patients. The general public indicated that they found it difficult to ask questions in pharmacies because other patients could hear what was discussed, or other patients had to wait longer if they asked something, and pharmacy staff being too busy. The results of the original pharmacist and the general public survey were confirmed by the results of the follow-up survey with the exception of dispensing prescription medicine (8 minutes 28 seconds), OTC medicine (7 minutes 23 seconds), counselling of prescription medicine (8 minutes 51 seconds) and OTC medicine (8 minutes) which on average took longer to conduct than in the previous analysis. The study highlighted the value added to the wellness and quality of life of the community of South Africa through the delivery of pharmaceutical care and pharmaceutical services by community pharmacy staff, and proved that pharmacists are committed to the provision of pharmaceutical care and pharmaceutical services.

- Description: Professional nurses working at a campus health service have to cope with challenges such as staff shortages and budgetary constraints associated with working in a complex environment providing primary health care. The aim of primary health care includes promoting health, preventing disease and the early detection and treatment of illness. Mental health services form an integral part of the integrated primary health care package as implemented in the campus health service. Students attend the Campus Health Service for help related to their health. Health care is provided by professional nurses and counsellors through a comprehensive primary health care service which serves students as well as staff. Some students may state that they experience feelings of being stressed or depressed. Other students may complain of physical symptoms such as headache or upper backache. Upon further investigation emotional problems may be identified as the cause of the psychosomatic symptoms. The professional nurses working in the campus health service verbalised that it is sometimes difficult to identify a mental illness or mental distress as there is no effective assessment tool that they can use. Management of conditions is also problematic as there are no protocols indicating the therapeutic interventions that can be taken. The research question in this study was therefore: What information should be included in a protocol to assess and manage a student experiencing mental distress that can be used by professional nurses working in a Campus Health Service? The aim of this study is to develop a mental health care protocol for campus health service professional nurses to assess and manage university students who are experiencing mental distress. The research design of this study was qualitative, explorative, descriptive, explanatory and contextual. In this study the Delphi research technique was used to create an instrument to standardise mental health care in a campus health service. The Delphi technique is a series of sequential questionnaires or “rounds” interspersed with controlled feedback that seeks to gain the most reliable consensus of opinion of a group of experts. A questionnaire was developed based on an extensive literature review. The research population of this study consisted of two groups: professional nurses with knowledge of student health care needs and expert psychiatric nurses. The study was conducted at the Campus Health Service at a university in the Eastern Cape. The data collection and analysis was done utilising the Delphi technique. Trustworthiness was ensured by using the Lincoln and Guba Model utilising the criteria of credibility, applicability, dependability and conformability. In this study the ethical principles of beneficence, non-maleficence, justice and self determination were applied to ensure that participants are treated with respect and consideration and ensured high ethical standards. Informed consent was obtained from the participants in this study. The findings of this research were utilised to assist the researcher in developing a protocol for mental health care of students in campus health service settings.

- Description: This study discusses reject film analyses (RFAs) before and after the implementation of a quality improvement intervention. RFAs were undertaken to investigate the effect of the introduction and use of exposure charts (ECs) on department and student reject rates of extremity radiographs. Methods: A quantitative comparative pre and post-treatment research design was used. Data was collected from the x-ray departments of two training hospitals in Windhoek, Namibia over a five month period. A retrospective RFA was conducted to determine the department and student reject rates for both departments before intervention. Emphasis was placed on exposure related reject films. ECs were compiled and introduced at Katutura State Hospital (venue B) by the researcher. The students were instructed to use these charts. At Windhoek Central Hospital (venue A) no ECs were used. A prospective RFA was conducted to establish department and student reject rates at both hospitals after the intervention at venue B. Results: During the retrospective phase the department reject rate for venue A was 21 percent while the student reject rate was 23 percent. At venue B 24 percent and 26 percent were scored respectively. Students at venue A produced rejected radiographs due to overexposure (49 percent) and underexposure (23 percent), whilst 37 percent was recorded for both causes at venue B. At venue A, 35 percent of films were rejected due to incorrect mAs selection, at venue B the figure was 42 percent. Undiagnostic radiographs due to inaccurate kV selection comprised 62 percent for venue A and 59 percent for venue B. During the prospective phase the department reject rate for venue A was 20 percent and that of the students was 19 percent. For venue B 12 percent and 11 percent were scored respectively. At venue A radiographs rejected due to over and underexposure were 43 percent and 33 percent respectively while those at venue B were 33 percent and 34 percent. Incorrect mAs selection caused 33 percent of discarded films at venue A and 38 percent at venue B. The figures for inaccurate kV selection were 68 percent and 62 percent for venues A and B. Conclusions: The introduction and use of ECs lowered the student reject rate at venue B in the prospective phase.

- Description: The aim of this study was to assess the effects of a twelve-week hydrotherapy group exercise programme on selected health-related fitness variables in older women with type II diabetes mellitus. This study included the testing of blood glucose levels, blood anthropometrical profile, body mass, height, body mass index, waist circumference, waist-to-hip ratio, upper body flexibility, lower body flexibility, grip strength, upper body and lower body muscular strength and endurance as well as aerobic endurance. Descriptive and inferential statistical techniques were used for this study utilising a quasiexperimental research design. A comparison group pre-test and post-test experimental design was employed at the Nelson Mandela Metropolitan University Biokinetics and Sports Science Unit. Approximately 16 senior female participants took part in the study. Participants were identified through convenience sampling and snowball sampling, of which, all the participants were clinically diagnosed with type II diabetes mellitus and had completed the study. The hydrotherapy participants (experimental group), took part in water-based (hydrotherapy) exercises three times a week for a period of twelve weeks. The hydrotherapy exercises began with a light half-hour workout per session and were progressively increased in intensity, duration, and number of the exercises performed. The participants not participating in the hydrotherapy exercises (control group) were instructed to remain sedentary throughout the duration of the intervention period. The dependant variables were gathered as raw data and analysed using descriptive statistics to form the means, standard deviations, medians, minimum and maximum values. Post hoc analysis was performed to determine whether differences existed between the experimental group and control group. Cohen’s D test was used to determine pre- and post-test differences for both groups to determine practical significance. An analysis of the results revealed significant improvements in some of the selected health and physical fitness parameters such as, upper body and lower body flexibility, upper and lower body muscular strength and endurance, as well as aerobic endurance. iii The aim and objectives of the study in exploring the effect of hydrotherapy as an intervention strategy to promote health and physical fitness in persons with type II diabetes mellitus were supported by the data collected in the pre-test and post-test analyses of the variables.

- Description: Breast cancer is the most prevalent cancer of women in South Africa, with one in twenty-seven women diagnosed with breast cancer in their lifetime. By building on human strengths, ways can be found to cope effectively with adversity. This will contribute to psychological well-being and result in living constructive and meaningful lives. Emotional intelligence and locus of control are two constructs which, according to previous research, may be associated with psychological wellbeing. Limited research has been conducted on these constructs in populations facing adversity. Adaptation to breast cancer treatment is considered to be an extremely difficult process. The research aimed to explore and describe emotional intelligence and locus of control within an adult breast cancer population. A sample of 67 breast cancer patients receiving treatment was approached to complete a biographical questionnaire and two pencil-and-paper questionnaires. Descriptive and inferential statistics were be used to analyze the data. The results of the quantitative analysis indicated a significant negative correlation between emotional intelligence and locus of control which shows that patients with higher levels of emotional intelligence possess more internal locus of control orientations, while patients with lower emotional intelligence possess more external locus of control orientations. The population presented with above average emotional intelligence and an internal locus of control orientation. The study can be regarded as the first step in opening a field of research which could contribute to more effective coping and the overall psychological well-being of individuals facing adversity in South Africa. Furthermore, the findings of the study contributed to understanding the role of emotional intelligence and locus of control in these populations and encouraged further research and the development and implementation of programmes that promote skills development in these areas.

- Description: Psychobiography is a qualitative approach to exploring and understanding the life story of an individual through the lens of psychological theory. The application of theory is typically done on the finished lives of well-known or enigmatic people. This study explores and describes the psychological development across the lifespan of Ernesto “Che” Guevara, by applying the Individual Psychology of Alfred Adler. Che Guevara was an Argentine Marxist revolutionary, physician, author, guerrilla leader, and major figure of the Cuban Revolution. Since his death, his image has become a symbol for revolution within popular culture. Extensive data has been examined in this work to ensure an accurate description of Guevara’s life. Alexander’s model of identifying salient themes was used to analyze the data within a conceptual framework derived from the theory. Guevara was fiercely loyal to his cause, at the expense of the lives of many Cuban citizens as well as his own family, whom he spent little time with. He justified this with his firmly held belief that the end justified the means and that he was always fighting for the greater good. He quite literally dedicated his life to his cause, which is the reason that he has become a modern day symbol for revolution. It is however unfortunate that this came at such a great personal expense.

- Description: Many South Africans are developing online relationships. Due to the anonymous and artificial context of the online environment it is possible that a person’s identity differs within the on- and offline environment. Sternberg’s (1986) Triangular Model of Love as well as Rogers’ Self Theory (1951) were utilized as a theoretical base for investigating online identity and intimacy. Using a qualitative, exploratory design, the study explored this phenomenon by analysing open ended questionnaires administered online to people in intimate online relationships. Participants were selected by means of non-probability snowball sampling. The findings indicated that Internet socialisers vary in their experience of their online identities. Individuals may have a multitude of genuine online selves, each one represented differently depending on the anonymity and level of intimacy in the relationship. Selfdisclosure and deception play an important role in identity representation and exploration and both are experienced as being affected by the online context.

- Description: South Africa, with an estimated 5.7 million people living with HIV, continues to have one of the largest epidemics in the world. The introduction of HAART resulted in prolonged and improved quality of life of many infected patients. However, adverse effects caused by these drugs have become a major concern as they affect the adherence of patients and in some cases even result in the death of patients. Although much research has been and is still being conducted in the area of understanding, preventing and management of ARV adverse effects, there is still a need for patients to be actively involved in self-monitoring for adverse effects. This will assist health care professionals in early identification of serious or potentially serious ARV effects. This study aimed at evaluating the usefulness of strategies developed and employed in the identification, recording and monitoring of adverse effects. The study was conducted with patients receiving HAART from a private HIV and AIDS clinic in Uitenhage, Eastern Cape, South Africa. The research project was approved by the Nelson Mandela Metropolitan University Research and Ethics Committee and the research site. This was an experimental, randomized controlled study carried out over a period of three months (August to October 2009), with a sample size of 160 patients divided into four study groups of 40 patients each. Two monitoring strategies, namely an ARV adverse effect monitoring tool and a patient self-monitoring diary were developed and used for the identification and recording of adverse effects. The four study groups included a Control group, a Tool group, a Diary group and a Tool-Diary group. Willing patients, after signing an informed consent form, were randomly assigned to one of the four groups by participating health care workers at the study site. Data was retrieved from the patient files by the researcher. Descriptive statistical analysis of the findings of the study was conducted using SPSS®. One hundred and forty nine patients were included in the final data analysis. Of the 80 diaries handed out to patients, only 33 were returned and due to errors only 31 were suitable for analysis. Monitoring tools were completed and analysed for 36 patients. The tool was found to be more effective in identifying adverse effects of a physical nature (such as peripheral neuropathy and lipodystrophy) than the usual methods of monitoring employed by the clinic, whilst the diary, used alone, was found to be less effective. Use of the tool and diary combined resulted in the most significant identification and recording of central nervous system related adverse effects and physical adverse effects. However due to the low return rate of the diaries and the majority of the monitoring tool not being completed in many instances the results of this study may not be generalisable. The study results did however suggest that combining the tool and the diary methods of adverse effect identification, yielded the most favourable results when compared to each method alone. This may be attributed to the fact that the tool is useful in identifying objective symptoms and the diaries subjective symptoms, particularly in instances where the patients forget to report their symptoms to healthcare professional whilst at the clinic. The diaries were also reported to improve adherence for more than 90 percentage (n=31) of the patients. More research would be needed in order to verify the exact significance of the tool and the diary in identifying and recording adverse effects and symptoms of adverse effects.

- Description: The overuse of antibiotics and consequent resistance is a common problem in medical practice worldwide. Switch therapy is a technique that can be applied to streamline antibiotic therapy reducing unnecessary prolonged Intravenous (IV) antibiotic therapy. Antibiotic switch therapy has several other benefits such as: decreasing length of hospital stay; decreasing the incidence of adverse events associated with the administration of IV antibiotics; decreasing direct and indirect hospitalisation costs while improving patients’ comfort and mobility; and decreasing the risk of acquiring nosocomial infections. Certain elements are required to make the implementation of any guideline, including a switch therapy guideline, a success and probably one of the most important is the support from a motivated multidisciplinary team. The role of such a team, in the South African context, would be filled by the Pharmacy and Therapeutics Committee (PTC). In addition, to make a guideline successful it should be continuously implemented. This responsibility traditionally falls to a pharmacist. In the United Kingdom (UK) and the United States of America (USA) pharmacists are used to promote the appropriate use of antibiotics in hospitals as this has shown to have several economic advantages. The objectives of the study were: to determine, by means of a survey, whether guidelines for IV to oral switch were employed in South African regional, tertiary and national government hospitals; to design and implement an IV to oral antibiotic switch therapy (IVOST) guideline for a local public sector tertiary level hospital; to evaluate the effectiveness of guideline implementation; and to capture, via a questionnaire, the perceptions of prescribers regarding antibiotic prescribing, including switch therapy. The Survey of Current IV Switch Therapy Practice Questionnaire was distributed to Responsible Pharmacists at regional, provincial tertiary and national central government hospitals to determine whether IVOST guidelines were employed in South African government hospitals. Following the survey, an IVOST Guideline was designed by the researcher in consultation with the Department of Medicine and the Department of Pharmacy. The IVOST Guideline was implemented following approval by the PTC at a local tertiary level government hospital. A presentation was held for prescribers, guideline documents were distributed, posters were placed in the medical wards and the ward pharmacist/researcher integrated the guideline into daily practice by placing “reminder stickers” in patient medical folders. A pre-implementation audit and two post-implementation audits, each consisting of 150 patient medical records, were conducted and compared to determine the effect of IVOST guideline implementation on prescribing patterns and to determine whether any changes could be sustained. The Prescriber Antibiotic Survey was then conducted to capture the perceptions of prescribers regarding antibiotic therapy, including switch therapy.

- Description: Antiretroviral drugs taken during pregnancy, reduce the rates of mother-to-child transmission from 35 percent to as low as 1 to 2 percent (UNAIDS, 2009). In 2002, the Prevention of Mother-to-Child Transmission (PMTCT) programme was implemented in South Africa. Studies on the implementation of the PMTCT programme have shown that understaffed and under-developed health care facilities were key barriers to the provision of PMTCT services (Health Systems Trust, 2002: 6; Skinner et al., 2003). The aim of this study was to assess the challenges experienced by health care workers working in public sector facilities in the Nelson Mandela Metropole after implementation of the dual therapy PMTCT programme. Four areas were investigated: Infrastructure; Drug Supply Management; Clinic Procedures and Staffing. A quantitative descriptive study was conducted in August 2009 at nine public health care facilities in the Nelson Mandela Metropole, South Africa. Questionnaires were issued to 81 nurses and 41 pharmacy personnel (pharmacists and pharmacist assistants). Checklist audit forms were issued to the Facility Manager of each facility and completed with the researcher. The key findings for Infrastructure were lack of space at patient waiting rooms (9; 100 percent n=9), counselling area (5; 55.5 percent; n=9), nurse consultation rooms (6; 66.6 percent; n=9), storage areas (5; 55.5 percent; n=9) and filing areas (7; 77.7 percent; n=9). The key findings for Drug Supply Management were none of the dispensaries (0 percent; n=10) were fully compliant with Good Pharmacy Practice, pharmacy personnel indicated that there were no stock cards for medication (13; 31.7 percent; n=41); there was less than two weeks supply of buffer stock kept for zidovudine and nevirapine (13; 35.1percent; n=37) and medication orders were placed without any reference to minimum and maximum levels of medication (15; 36.5 percent; n=41) . The key findings for Clinic Procedures were only two facilities followed up on patients that had missed appointments (22.2 percent; n=9) and four facilities (44.4 percent; n=9) had a tracking system for patients that had defaulted. Of the nine facilities only three (33.3 percent; n=9) updated patient demographic details regularly. The key findings for Staffing were a shortage of doctors, nurses, counsellors and pharmacists at the facilities. One of the major challenges identified was the lack of training offered on new PMTCT protocols with 56.2 percent (45; n=80) of the nurses stating that no training was provided on the dual PMTCT protocol. Only 54.3 percent (44; n=81) of nurses stated that they knew the criteria to start the mother on dual PMTCT therapy. In conclusion there is an urgent need for barriers such as lack of staff, lack of space, lack of training on PMTCT and standard procedures for follow up of patients to be addressed in order to ensure the successful scaling up of PMTCT.

Managerial decision making processes and affective outcomes as a function of individual factors and self-efficacy beliefs

- Description: Making decisions in the business environment is arguably the most challenging aspect of managers' yet also the easiest to fail in. Unlike individual decisions managers as agents for their organizations make decisions amidst high levels of ambiguity, incomplete information and mostly under time pressure. These are the very conditions that make managers vulnerable to the volition-undermining potential of decision-generated affect precisely when they are feeling over-extended to deal with such demands. Effective managerial decision making (MDM) involves more than applying a set of individual abilities. Managers face numerous obstacles, failures, and setbacks that often carry perturbing self-evaluative implications as well as social consequences that undermine their self-evaluations in ways that impair good use of their decision making skills (Bandura, 1997). Given the absence of a coherent theoretical framework in the literature the conceptual model of relations put forward attempts to organize and simplify how managers make decisions as agents of their organizations. Most conceptualizations apply oversimplified models that focus attention on one or a few variables, neglect the joint constellations of individual variable factors and the influence of individual self-generated influences as a contributing factor in MDM.

Structural equation modeling (SEM) was chosen as the data analysis strategy of choice and a confirmatory factor analysis (CFA) demonstrated that the operational measures by and large succeeded in providing both a comprehensive and empirical grasp on the constructs as defined. The inter-construct relations were also consistent with expectations. Evidence for convergent validity however proved that the indicator measures for the allocation of attentional resources were less than adequate in order to provide an uncontaminated measure as a latent variable. The structural model was subjected to further scrutiny by way of a spectrum of goodness-of-fit statistics. The analyses revealed that the model was not adequate and the null hypothesis that the model fitted the population data was subsequently, rejected. It was also sensible to assess the degree of lack of fit of the model with reference to RMSEA which revealed a value of .08, that suggested a reasonable model fit. The poor structural model fit could however be attributed to the failure of the measured indicators used to provide an acceptable grasp of the allocation of attentional resources as a latent variable. The inherent structural flaws in the model could however not be unequivocally be ruled out as an additional possibility of poor fit. One conclusion is the possibility of an expanded model that requires additional indicator measures and additional paths. Notwithstanding these limitations, the present research provided support for social cognitive theory that underlies the model. In accordance with the literature and empirical findings the present research demonstrated mangers' decision making is much more than reason-based behaviour. The present research demonstrates the interdependencies and cumulative effects among individual factors, self-efficacy beliefs and temporal volitional processes, as psychological iv mechanisms through which social-structural factors are linked to the quality of MDM processes. The present research also presents an argument for the independent contributions of self-efficacy beliefs as causal influences on "hot temporal processes" that promote accuracy in decision making. Although present research demonstrates that the estimates were greater for cognitive ability than for both self-efficacy beliefs and social self-confidence it does not suggest that personality traits and self-efficacy beliefs have no utility. The present research demonstrates that cognitive ability combines with personality traits, self-efficacy beliefs and temporal processes (decision-generated affect and the allocation of attentional resources) in a complex manner through multiple pathways.

- Description: Making decisions in the business environment is arguably the most challenging aspect of managers' yet also the easiest to fail in. Unlike individual decisions managers as agents for their organizations make decisions amidst high levels of ambiguity, incomplete information and mostly under time pressure. These are the very conditions that make managers vulnerable to the volition-undermining potential of decision-generated affect precisely when they are feeling over-extended to deal with such demands. Effective managerial decision making (MDM) involves more than applying a set of individual abilities. Managers face numerous obstacles, failures, and setbacks that often carry perturbing self-evaluative implications as well as social consequences that undermine their self-evaluations in ways that impair good use of their decision making skills (Bandura, 1997). Given the absence of a coherent theoretical framework in the literature the conceptual model of relations put forward attempts to organize and simplify how managers make decisions as agents of their organizations. Most conceptualizations apply oversimplified models that focus attention on one or a few variables, neglect the joint constellations of individual variable factors and the influence of individual self-generated influences as a contributing factor in MDM. As an ex post facto explanatory-predictive study the present research offers evidence of these links among the theoretically relevant constructs in order to formulate an account of their relations in a parsimonious framework that could guide future insights to explain and predict the intentions and direction of managerial decision behaviour. Conceptual research has outpaced empirical research in decision making of managers in organizations. A number of mini-theories exists that focus on a few variables using linear, antecedent-consequence relations with manipulations in laboratory environments that deal with decisions in contexts that are very different to those faced by managers.
