- Description: Research problem: The restructuring of an organisation can be classified as a transformational intervention (Litwin & Burke, 1992). As such is it has a potential to significantly influence key employee attitudes that are related to employee and organisational performance. Any deterioration in these attitudes could impact negatively on organisational outcomes. As part of the monitoring and review of change interventions, management needs to understand the change in employee attitudes towards their work and management in their business units and towards the broader organisation in order that, if necessary, corrective action can be taken. Research objectives: To address the research problem, research objectives and questions were established. The main objective of the study was to investigate whether there has been a change in attitudes of employees in two business units of a South African National Science Council after the implementation of restructuring in the organisation and the business units. The key attitudes to be measured are job and management satisfaction, perceived organisational support, organisational commitment and a dimension of employee engagement, dedication. Research questions: Four research questions were established and these were; What is the change in employee attitudes post-restructuring? In particular what is the change in employee job satisfaction; management satisfaction, employee engagement, commitment to the organisation and perceived organisational support? What is the relationship between the sub-groups, distinguished by gender, occupational level, race, home language, age, number of years of service and business unit, and employee attitudes pre-restructuring? What is the relationship between the sub-groups distinguished by gender, occupational level, race, home language, age, number of years of service and business unit, and employee attitudes post-restructuring? What is the relationship between the sub-groups distinguished by gender, occupational level, race, home language, age, number of years of service and business unit, and the change in employee attitudes pre and post-restructuring? Research design: The nature of this research is descriptive. In order to solve the research questions the researcher used a pre-test and post-test measurement of employee attitudes. A survey using a structured self-administered questionnaire was used to collect information regarding employee attitudes before and after the restructuring of the organisation and business units. Major findings: The results from the survey showed that there was a change in the levels of organisational commitment, job satisfaction and management satisfaction at the National Science Council after the restructuring had taken place. Also, the impact of the sub-groups in the organisation on affective factors was evident in the level of occupation and employee engagement, race and management satisfaction, the business unit and the levels of perceived organisational support, management satisfaction and employee engagement, home language and employee engagement, the number of years the employee had worked for the organisation and management satisfaction, age and job satisfaction and employee engagement.

- Description: Bullying appears to be a worldwide phenomenon. It occurs within schools, homes, and in the community too. Bullying is a form of aggressive behaviour. Female bullying is not so easily noticed, as girls hardly ever use physical forms of aggression. Bullying can have a detrimental effect on the mental health of the victim. The victims of bullying experience symptoms of mental discomfort, which include low self esteem, feelings of helplessness, feelings of worthlessness and inferiority, lack of confidence, isolation, self-conscientiousness; and lastly, this can lead to suicide. Some form of intervention is necessary to provide adolescents with skills to combat bullying and help them to become mentally healthy again. The overall goal of the study was to develop, implement and evaluate a psycho-educational programme for female adolescents in a secondary school setting, in order to assist them in coping with bullying. The objectives of the research study were to: Conduct asituational analysis to identify the mental health needs of adolescent girls, as victimsof bullying. Develop a psycho-educational programme to facilitate the promotion of mental health of those adolescent girls who are victims of bullying. Implement the psycho-educational programme to facilitate coping by adolescent girls who are victims of bullying. Assess whether the adolescent girls have benefitted from attending the psycho-educational programme. The researcher used a qualitative, explorative, descriptive and contextual design. The research methodology consisted of four phases. In phase one of the research, a situational analysis was done; and the characteristics of mental discomfort exhibited by the victim were identified. The needs of the adolescent girl who has been bullied have already been described. Phase two involved the development of a psycho-educational programme. The information from the situational analysis was used to develop the conceptual framework. The six concepts in the survey list of Dickoff et al. (1968:422) were described as follows: the recipient is the adolescent girl who has been bullied, the agent is an advanced psychiatric nurse, the context is the community and the secondary school where bullying takes place, the dynamics of the intervention constitute the mental discomfort experienced by the adolescent girl. This is what motivates her to participate in the programme. The procedure was identified as the psycho-educational programme, while the terminus or outcome of the intervention for the adolescent girl would be for her to experience mental health after being exposed to the psycho-educational programme. The relationship between the concepts was used to form the mind map of the conceptual framework. This guided the development of the psycho-educational programme. The content of the programme has already been described. In phase three the psycho-educational programme is implemented and in phase four the programme is evaluated. The psycho-educational programme taught the teenage girls skills and it provided them with knowledge to cope better with the bullying. Attending the programme made the teenagers aware that they needed to change to experience mental health and happiness. The empirical study took place in phase four. The data-gathering method in phase four included the conducting of semi-structured interviews with the adolescent girls who participated in the programme, as well as the teachers of these adolescent girls and their parents. Naïve sketches, reflective journals, observations made and field notes formed part of this database. The data was analyzed by means of Tesch‟s descriptive analysis (in Creswell, 2003:192). The participants had to comment on how they were coping after the implementation of the psycho-educational programme. In conclusion, an intervention in the form of the psycho-educational programme was shown to be beneficial to adolescent girls who were victims of bullying, to assist them in coping with the aftermath of being bullied. Recommendations were made to enhance nursing practice, as well as nursing education and nursing research. Keywords: Adolescent girls, bullying, secondary schools, advanced psychiatric nurse, psycho-educational programme, mental health.

A psychobiographical study of John Winston Lennon

- Description: Psychobiography can be viewed as the re-writing of an individual’s life story previously undetected. In general it consists of a combination of two central elements: biography and psychological theory that aim to explain the particular individual’s psychological development. This particular study serves to explore the extraordinary life of renowned singer, songwriter, artist and activist, John Winston Lennon (1940-1980). The basis for this investigation will take the form of notable biographical accounts of the subject’s life, together with Austrian psychiatrist Alfred Adler’s (1938) theory of Individual Psychology, which recognizes the importance of human society for the development of individual character and the orientation of every single action and emotion in the life of a human being. Adler’s theory further explores that the main motives of human thought and behaviour are an individual’s striving for superiority and power, partly in compensation for his feeling of inferiority. The psychobiographical data collection and analysis for this research thesis will be guided by Yin’s (1994) theory of ‘analytic generalisation’, which uses a theoretical framework in selecting relevant data which develops a matrix as a descriptive framework for organizing and integrating that data, and Alexander’s (1988) analytical model which focuses on lifting out themes through principal identifiers of salience was used and applied. John Winston Lennon expressed his personal experiences and ideals through his songs and became the spokesman for his generation on modern day issues such as feminism and world peace. It is however, unfortunate that Lennon throughout his life remained a boy who felt rejected and unloved by his parents and strove to be superior in all aspects of his rich life in an attempt to acquire the love and acceptance that was not bestowed on him as a child.

A psychobiography of Friedrich Nietzsche
- Authors: Booysen, Duane Danny-Coe

- Subjects: Nietzsche, Friedrich Wilhelm, 1844-1900 , Philosophers -- Germany -- Biography

- Description: The primary aim of this psychobiography was to examine Friedrich Nietzsche’s life by utilizing Carl Rogers’ theory of the fully functioning person. Friedrich Nietzsche (1844 - 1900) has become an iconic figure in German philosophy and literature. Nietzsche’s criticism of western morality and culture led him to believe that humankind was not living to its highest potential and consequently Nietzsche sought after a life of self-becoming. Nietzsche’s philosophy has influenced various people such as Viktor Frankl, DH Lawrence, Michel Foucault and NP van Wyk Louw. Nietzsche was chosen as the research subject because of personal interest, his prominence as a philosopher, and because of his ambition to live a meaningful life. Psychobiographical research with the use of psychological theory allows for the exploration and description of the life of an individual. This significant area of research involving the application of psychological theory has in previous decades, however, been under-utilized, particularly in South Africa. But more recently, has it been receiving increasing support by researchers both internationally and in South Africa. Data collected on Friedrich Nietzsche’s life were drawn from several primary and secondary sources. A data collection and analysis grid was developed in order to collect data systematically, and to analyse the data according to the qualities of Carl Rogers’ theory. The study adds to the body of psychobiographical research. It also provides an empirical exploration of Carl Rogers’ theory of the fully functioning person. As the scope of the study was that of a master’s dissertation, future research, utilising semi-structured interviews with knowledgeable relatives, academics, psychologists, biographers, philosophers and historians on Nietzsche’s life, could extend this line of research. In conclusion, the current psychobiography suggests that Nietzsche lived a life filled with several personal crises. Despite these challenges, Nietzsche directed himself towards living as a fully functioning person. Nietzsche’s impetus towards self-becoming is also evident within his philosophical writings. Nietzsche was an extraordinary individual whose life, as described in the current psychobiography, corresponds closely to Rogers’ (1961) theory of a fully functioning person.

- Description: The assessment of the motivational value of rewards in the world of work is interesting but difficult to understand. Variations in research reports and inadequate comprehension of the efficiency and motivational value of rewards have brought about confusions, controversies and contradictions among authors, researchers, consultants and practitioners in the field of Industrial and Organisational Psychology (Mangham, 2007; Muula, 2006; Muula & Maseko, 2005; Palmer, 2006; World Bank, 2004). As a consequence, organisations are applying theories and models of motivation selectively depending on their beliefs, ideological framework of values and assumptions (Dzimbiri, 2009). The study was therefore carried out as a positive contribution to the existing knowledge and debate on the motivational value of rewards for health professionals in the public health sectors of the developing countries. Through a systematic sampling method, 571 health professionals were sampled for the study. Data were collected through the use of a self-administered questionnaire which was composed based on the data collected from desk research/literature review, focus group discussions and interviews. The findings of the study revealed that the Malawi‟s Ministry of Health (MoH) is failing to attract, motivate and retain health professionals; there is perception of inequity of the rewards among the health professionals; health professionals develop coping strategies to supplement their monthly financial rewards; health professionals engage in corrupt practices to supplement their monthly financial rewards; and there is erosion of industrial democracy in the Malawi‟s Public Health Sector. While the statistical testing of the hypothesized model proved a lack of fit between the variables, the statistical testing of the re-specified model suggests that there is a positive relationship between financial rewards and reward-related problems being faced by health professionals in the Malawi‟s MoH. Through the Structural Equation Modeling (SEM) exercise, an inverse (negative) relationship between financial and non-financial rewards was deduced, and scientifically and graphically demonstrated. Both the re-specified and graphical models symbolize a pragmatic departure from the theoretical model whose authors (Franco, Bennett, Kanfer & Stubblebine, 2004) are largely inclined to the use of non-financial rewards and suggest that financial rewards should be used with caution. These findings also reject the Herzberg‟s two factor theory (Herzberg, 1960) which claims that financial rewards (salaries) are not a motivator. The major recommendations of the study are that the Franco et al.‟s (2004) model should be adopted and adapted in the Malawi‟s MoH with the view that the value of both financial and non-financial rewards (as motivators) varies from individual to individual due to individual differences and prevailing factors/forces in both the work environment and wider society in which the MoH operates; a hybrid reward system combining the strengths of time-based, performance-based and competence-based reward systems should be developed and implemented; the results of scientifically testing the re-specified model and the inverse (causal) relationship established between financial and non-financial rewards (as demonstrated in a graphic model) should be re-tested with other samples in the public health sectors of the developing countries; and the motivational value of non-financial rewards should be scientifically established and compared with the motivational value of financial rewards used independent of each other in business organisations to make an objective conclusion on the rewards-motivation debate.

- Description: The aim of the study was to delineate, discuss and analyze major challenges that affect children between the ages of 13 and 18 in the Nyandeni area due to HIV/AIDS. This exploratory study was also performed to identify the categories of children made vulnerable by HIV/AIDS. One of the objectives was to provide a descriptive and analytical interpretation of the day to day experiences of children affected by HIV/AIDS. In shaping the sample size, 50 respondents were selected from three wards (2, 3 and 16) of the Nyandeni Local Municipality in the Nyandeni area in the Eastern Cape.The researcher made use of the interview technique to collect data from the respondents.

- Description: Workplaces are required by law to provide HIV and AIDS workplace programmes to educate and prevent the spread of HIV, and stigmatisation and discrimination against workers infected or affected by HIV and AIDS. This study was a descriptive cross-sectional study conducted in the public and private sector at Mt Fletcher in the Eastern Cape Province. It aimed at assessing the availability and implementation of HIV and AIDS workplace programmes at Mt Fletcher. The study’s objectives were: to assess knowledge of HIV and AIDS among employees; to determine the availability of HIV and AIDS psychosocial programmes; to assess the employees’ knowledge on HIV and AIDS workplace guidelines that prevent stigma and discrimination. This was a quantitative study. A self-administered questionnaire was used to collect data. A total of 81 respondents from both public and private sectors participated in the study. Stratified random sampling was used to select participating workplaces. Simple random sampling was used to select respondents. The findings indicated that both public and private sector workplaces have HIV and AIDS programmes. However, all private sector workplaces at Mt Fletcher had no onsite clinic as required, but use the local public HIV and AIDS clinics. However, 24% of public and 23% of private sector employees had no knowledge of the existence of the HIV and AIDS programmes at their workplaces. About 13% of public and 10% of private sector employees indicated that stigmatisation and discrimination against people living with HIV and AIDS was a problem in the workplace. They also indicated that they would not disclose their HIV status to their employers because they were afraid of losing their jobs. The lack of disclosure further disadvantages workers living with HIV as they do not get the support they deserve from their employers. Furthermore, lack of support, stigma and discrimination have an impact on the performance and productivity of the infected and affected employees and therefore affecting the expected output of their workplaces.

- Description: Children have been shown to respond differently to the hurt that they suffer at the hands of others. Some of these responses involve internalised behaviours (i.e., repression of feelings, bodily symptoms, etc.); whilst others hurt manifest as externalised behaviours, such as physical attacks on others. These may include sexualised behaviours. The latter is particularly common amongst (but not restricted to) children who have been sexually abused (The American Psychological Association, 2001). For the purposes of this study a distinction is made between developmentally appropriate sexual behaviour and non normative sexualised behaviour which evoke complaints from and discomfort in those involved in the behaviour. The manifestation of these sexualised behaviours is especially pronounced amongst children in institutional care; and hence, it calls for constructive and effective management by the child care workers who are primarily responsible for their safe care and behaviour modification whilst in the institution. This qualitative study – with an exploratory, descriptive and contextual research design – served to explore how the child care workers’ effective management of such behaviours could be enhanced, so that the emotional wellbeing of both the “offender” and the “perpetrator” of this behaviour can be promoted. A non-probability purposive sampling technique was employed to recruit research participants from three different child and youth care centres in Port Elizabeth. A total number of 10 research participants were involved and data was collected up to the point of data saturation. Thematic content analysis was utilised for the analysis of the data and the necessary strategies were employed to enhance the trustworthiness of the data and to meet all the ethical requirements of the study. The main findings alert to the key requirements of Child and Youth Care Workers; it confirms the occurrence of sexualised behaviours; the urgent need for a consistent approach to the management of such behaviours; and for enhanced team work between the helping professionals in the team. The value of the study is embedded in the contributions it can make to practical interventions for children in institutional care, and to the sparse body of knowledge in this area.

- Description: South Africa as a country is known for its high crime rate which produces an ongoing traumatising environment for its multicultural nation. Posttraumatic stress disorder in the general South African population is thought to be more prevalent than most international norms which make this topic both relevant and important. Cultural diversity is seen to play a role in the experience of PTSD which means that it has become important to gain an understanding of the potential effect of the individual’s cultural background on the processing of a traumatic experience and the symptoms related to the experience. The proposed research focused on appraisals of the traumatic event and symptoms (in schematic and cultural terms). An interpretive (with current cognitive conceptions of the disorder as guiding theory) phenomenological approach was used. The sample consisted of eight isiXhosa-speaking adults that qualified for a diagnosis of PTSD with no prior psychiatric diagnosis. Data was gathered using a semi-structured interview and analysed using the Interpretive Phenomenological Analysis. Results indicated that participants understood their PTSD symptoms in a functional manner but struggled to make sense of their traumatic event. Not understanding their traumatic event was the variable that maintained their PTSD diagnosis. Most of the interpretations made by these participants were fairly universal and there were very few links to content that can directly be attributed to a traditional African worldview. Practitioners may not need to completely reinvent the wheel as far as treatment strategies for PTSD for isiXhosa-speaking individuals in an urban setting go.

- Description: Background: Worldwide, prices for cancer drugs have been under downward pressure where several governments have mandated price cuts of branded and generic products. A better alternative to mandated price cuts would be the estimation of a launch price based on drug performance, cost effectiveness and a country’s ability to pay. In this study, the development of a global pricing index for new drugs that encompasses all of these attributes in patients with metastatic colorectal cancer (mCRC) is described. Methods: A pharmacoeconomic model was developed to simulate clinical outcomes in mCRC patients receiving chemotherapy with the addition of a “new drug” that improves survival by 1.4, 3 and 6 months. Cost and health state utility data were obtained from cancer centers and oncology nurses (total n=112) in Canada (n=24), Spain (n=24), India (n=24), South Africa (n=16) and Malaysia (n=24). A price per dose was estimated for each survival increment using a target value threshold of three times the per capita gross domestic product (GDP) for each country, as recommended by the World Health Organisation (WHO). Multivariable analysis was then used to develop the pricing index, which considers survival benefit, per capita GDP and income dispersion as measured by the Gini coefficient as predictor variables. Results: Higher survival benefits were associated with elevated drug prices, especially in wealthier countries such as Canada and Spain. For a nation like Argentina with a per capita GDP of $15,000 and a Gini coefficient of 51, it is estimated that for a drug which provides a 4 month survival benefit in mCRC, the value based price would be $US 630 per dose. In contrast, the same drug in a wealthier country like Norway could command a price of $US 2,775 and still be considered cost effective according to the WHO criteria. Conclusions: A global pricing index was presented that can be used to estimate a value based price in different countries for new drugs in mCRC. The application of this index to estimate a price based on cost effectiveness would be a good starting point for opening dialogue between the key stakeholders and a better alternative to governments’ mandated price cuts.

- Description: The development and implementation of policy guidelines remains a contentious issue. Over the past few years, difficulty still exists in implementing the Department of Education (DoE) 1999, National Education Policy Act, 1996 (No. 27 of 1996): National Policy on HIV/AIDS for learners and educators in public schools, and students and educators in further education and training institutions [here after referred to as DoE HIV/AIDS policy (1999)], while at the same time trying to transform the entire education system. This research explored the perceptions of educators in the Port Elizabeth District regarding the implementation of DoE HIV/AIDS (1999) policy guidelines. A secondary objective was to provide a reflection of how the implementation of guidelines on HIV/AIDS interventions within the schools of the Port Elizabeth District either conformed to or deviated from the guidelines outlined in the DoE HIV/AIDS policy (1999). The study was executed within the paradigm of qualitative research and employed an exploratory, descriptive and contextual design. The researcher conducted a pilot study to enhance the trustworthiness of the study. Purposive sampling was employed to recruit research participants, consisting of 12 educators from 10 schools in the Port Elizabeth District where HIV/AIDS interventions were being implemented. Data was gathered through semi-structured interviewing and analysed using Tesch’s (1990) in De Vos, Strydom, Fouché & Delport (2005:340-341) framework for analysis of qualitative data. Guba’s model (in Krefting, 1991) was used to ensure the trustworthiness of the study. Three themes emerged from the results of the in-depth semi-structured interviews: (1) Educators’ views on the DoE HIV/AIDS policy (1999) guidelines and its implementation (2) Gaps or shortcomings in implementation of the DoE HIV/AIDS policy (1999) and (3) Educator suggestions’ to inform implementation of the DoE HIV/AIDS policy (1999) in schools. The results from the study indicate that there is inconsistency in the policy implementation approach employed by DoE district level representatives and there is a need for knowledge and capacity development at district and school level. The value of the study is outlined as well as recommendations.

- Description: The aim of the study was to explore, describe and compare the impact of a 12-week intervention on selected physical fitness variables in sub-elite martial artists. The experimental group (expG) participated in a combination of alternating dojo and gymnasium-based resistance training, each bi-weekly, with the comparison group (comG) exclusively undergoing four conventional dojo training sessions weekly. The variables measured included; anthropometric measures (height, body mass and percentage body fat); functional core muscular endurance; hamstring flexibility; upper body muscular strength and endurance; lower body muscle strength; and static balance. A quasi-experimental research design was employed, with pre - and post - test assessments after a 12 week intervention period. Purposive and snowball sampling techniques were employed from existing dojo’s in Port Elizabeth, with a randomised allocation of participants into two groups. The gymnasium-based training programme was designed according to the national conditioning and strength association (NCSA) principles of resistance training. The identified variables were tested at a 95% level of probability (p < 0.05). Similar trends in performance improvement were evident for both the expG and compG in of the majority of the selected physical fitness variables. One-way, two-sample and independent t-tests analysis found no statistical significant intra- group or inter-group differences in any of the selected dependant variables for both groups. Thus, the supplemental resistance training programme was not superior to that of the conventional dojo training programme in improving aforementioned variables. Despite the lack of statistical significance, these results indicate that a structured and supervised resistance training programme in a gymnasium may serve as an alternative method of intervention for improving physical fitness in sub-elite mixed martial artists. The resistance training programme should be specifically adapted according to the individual practitioner’s strengths and weaknesses, as well as to the type of martial art being practised.

- Description: The aim of this study was to develop a standardised set of Environmental-Health work methods and procedures, with the purpose of contributing to the effective surveillance and control of Cholera in the KwaZulu-Natal province, South Africa. The researcher followed a qualitative research design, which was explorative, descriptive, inductive and deductive by nature. The methods of data collection were documentary research and focus-group interviews. A documentary research approach was employed as the primary method of data collection for the study. The researcher has used semi-structured questions to obtain relevant information from the participants in the focus groups. The purpose of using semi-structured questions in the focus groups was to draw on their knowledge and experience of communicable disease surveillance and control in relation to Cholera, as well as to ascertain their views on the role of the Environmental-Health Practitioners in the Communicable - Disease Outbreak- Response Teams at the three different spheres of government. The process of qualitative data analysis was followed. This was based on data reduction and interpretation; and it was conducted as an activity simultaneously with data collection, data interpretation (coding) and narrative writing. The information obtained from the analysed data assisted in the development of the environmentalhealth work methods and procedures for the surveillance and control of Cholera in the KwaZulu-Natal province, South Africa. In this study, firstly, the epidemiology of Cholera was described and analysed against the background of its manifestation in South Africa. Secondly, the national health care system, with specific reference to the place and role of environmental health practitioners at national, provincial and municipal spheres – in relation to Cholera surveillance and control – was analysed. Thirdly, the relevant research that has been done globally has been analysed against the background of the findings of the above, together with work methods and procedures to be used by environmental-health practitioners during the surveillance and control of Cholera in the KwaZulu-Natal Province, South Africa. These include, inter alia: Work methods and procedures for Cholera case investigation; Work methods and procedures for sanitary investigations; and Work methods and procedures for identifying the sources of contamination in environmental waters. Finally, the conclusion and limitations was presented, and appropriate recommendations were made. These include: he need to educate all role - players, on the recent developments in the identification of Vibrio cholerae from environmental surface waters; Communication systems should be developed that allow the Director: Environmental Health to communicate urgent environmental health information directly to the Minister of Health; he training of environmental-health practitioners on detailed work methods and procedures for the surveillance and control of Cholera; and the existing national Cholera control guidelines need to be updated to include relevant environmental health situations when emergencies arise.

The purpose of using semi-structured questions in the focus groups was to draw on their knowledge and experience of communicable disease surveillance and control in relation to Cholera, as well as to ascertain their views on the role of the Environmental-Health Practitioners in the Communicable - Disease Outbreak- Response Teams at the three different spheres of government. The process of qualitative data analysis was followed. This was based on data reduction and interpretation; and it was conducted as an activity simultaneously with data collection, data interpretation (coding) and narrative writing. The information obtained from the analysed data assisted in the development of the environmentalhealth work methods and procedures for the surveillance and control of Cholera in the KwaZulu-Natal province, South Africa. In this study, firstly, the epidemiology of Cholera was described and analysed against the background of its manifestation in South Africa. Secondly, the national health care system, with specific reference to the place and role of environmental health practitioners at national, provincial and municipal spheres – in relation to Cholera surveillance and control – was analysed. Thirdly, the relevant research that has been done globally has been analysed against the background of the findings of the above, together with work methods and procedures to be used by environmental-health practitioners during the surveillance and control of Cholera in the KwaZulu-Natal Province, South Africa. These include, inter alia: Work methods and procedures for Cholera case investigation; Work methods and procedures for sanitary investigations; and Work methods and procedures for identifying the sources of contamination in environmental waters. Finally, the conclusion and limitations was presented, and appropriate recommendations were made. These include: he need to educate all role - players, on the recent developments in the identification of Vibrio cholerae from environmental surface waters; Communication systems should be developed that allow the Director: Environmental Health to communicate urgent environmental health information directly to the Minister of Health; he training of environmental-health practitioners on detailed work methods and procedures for the surveillance and control of Cholera; and the existing national Cholera control guidelines need to be updated to include relevant environmental health situations when emergencies arise.

- Description: Operating room nursing skills are some of the most demanding skills in the nursing profession. At the moment nurses trained in operating room technique are in very short supply in Ethiopia, due to the exodus of nurses to better working environments with more reasonable payment. This is especially noticeable in one of the state hospitals in Addis Ababa, Ethiopia, as emerged in conversations with the head nurse of the operating room in this hospital about the high turnover rate, as well as the high absenteeism rate amongst the nurses working in the operating room. Nurses working in the operating room also expressed unhappiness in their work environment which could cause them to look for other jobs or to be absent from duty. The nurses were facing numerous problems in their work environment such as work overload due to staff shortage, stress due to shortage of supplies because they are not able to do their job as much as the need requires. The researcher identified the need to explore the challenges that the operating room nurses are experiencing in their work environment. The researcher used the following questions to meet the research objectives: What are the experiences of the operating room nurses in their work environment?; What potential assistance would such nurses need to better cope with the problems they experience in their work environment? The research study aimed to explore and describe the experience of operating room nurses in their work environment and on the basis of the findings to develop guidelines to assist the operating room nurses in coping more effectively with their work environment. The researcher used a qualitative approach with an explorative, descriptive and contextual design. Fifteen registered nurses were selected using purposive sampling. Informed consent was obtained from the participants and permission from the Ethics Committee of the Nelson Mandela Metropolitan University, as well as Yekatit 12 Hospital. Data were gathered using face to face interviews and field notes were taken to determine the experiences of the participants. Data were analyzed using Tesch's method of descriptive data analysis (in Creswell, 2003:13). Two main themes with two sub-themes related to the experience of the registered nurses working in the operating room of the state hospital were identified. Main theme one focused on the non-conducive work environment and it focused on the lack of support from management and the problems experienced in the environment. It was found that OR nurses had good working relationships among the nursing staff. Main theme two focused on the limited training opportunities in OR techniques. The sub-themes described the limited exposure to new technology and the quality of nursing education which the participants felt was not taken seriously in Ethiopia. Based on the identified themes guidelines were formulated to assist the registered nurses working in the operating room of a state hospital in Ethiopia. Utilization of these guidelines should assist the registered nurses to cope more effectively with their work environment. Recommendation were made, further research and limitations identified.

- Description: Phenylephrine hydrochloride is a potent adrenergic agent and β-receptor sympathomimetic drug, used in its optically active form (Pandey et al., 2003; Pandey et al., 2006). As an α1-adrenergic receptor agonist, phenylephrine hydrochloride is used ocularly as a decongestant for uveitis and as an agent to dilate the pupil (Lang, 1995). High intraocular doses have been reported to cause tachycardia, hypertension, and headache. These side effects are caused by large amounts of the drop draining into the nasal cavity. Eye drops that contain phenylephrine hydrochloride have proven to have low intra-ocular bioavailability because of a short contact time with the eyes which reduces the amount of drug reaching the site of action. Formulations of phenylephrine hydrochloride eye drops have varying shelf-lives of approximately two to four years. The aim of this study was to formulate and manufacture an eye drop product containing phenylephrine hydrochloride. Important characteristics that were targeted were increased ocular absorption by increasing the viscosity of the product and reduced degradation of phenylephrine hydrochloride. A variety of phenylephrine hydrochloride formulations were manufactured on a laboratory scale using hydroxypropyl methylcellulose (HPMC), glycerol, and sodium carboxy methylcellulose as viscosity modifying agents (VMA). The concentration of phenylephrine hydrochloride was ten percent. Ten millimeters of each formulation was made in triplicate. The quantity in each was evaluated using a previously validated high performance (pressure) liquid chromatography method. Physicochemical properties including pH and colour were also evaluated. Stability was assessed using real time and accelerated stability conditions in accordance with the International Conference on Harmonization (ICH) guidelines. Formulations containing hydroxypropyl methylcellulose (HPMC) as the viscosity modifying agents proved to be stable under all storage conditions when compared with formulations containing other viscosity modifying agents (VMA). However, sodium citrate dihydrate; sodium metabisulphite and EDTA also stabilized the formulations to a certain extent Changes in the appearance and colour of products containing glycerol under accelerated storage conditions were observed. The sodium carboxy methylcellulose (SCMC) containing formulation was found to be physically and chemically stable in two conditions, namely 30 °C/65 percent RH and 25 °C/60 percent RH. The formulations containing hydroxypropyl methylcellulose along with an antioxidant showed to be most stable as it remained aesthetically pleasing did not change colour and did not have a reduction in phenylephrine hydrochloride concentrations. This meant that phenylephrine hydrochloride did not degrade while the viscosity modifying agents remained stable. Rheological tests showed differences in the viscosities of the formulations as glycerol had increased in viscosity over time while HMPC and SCMC displayed relative similarities. The formulations were compared to a marketed eye drop containing polyvinyl alcohol as a VMA. After rheological analysis the formulation containing HPMC displayed better viscosity than the product with polyvinyl alcohol. The preservatives in the formulations were active against the microbial organisms use to challenged them.

- Description: The study consists of a psychobiography of the British artist, Francis Bacon (1909-1992). Psychobiography employs a qualitative approach to understanding the life story of an individual through the lens of psychological theory. It is typically dedicated to the lives of well-known or enigmatic people and covers the person’s entire lifespan. For this study the analytical theory of Carl Gustav Jung (1875-1961) is used to explore and describe Bacon’s life and personality through concepts relating to personality functioning, history, mythology, anthropology, symbology and religion. Francis Bacon has captured the imagination of the art world for many years - especially where it is felt that the figure-subject is still the highest form of art - and his reputation among the foremost of English painters is assured. Coupled with his artistic output is a life full of curiosity, eccentricity and controversy. This alone would qualify him as a suitable subject for a study such as this, but his extraordinary oeuvre of painting hugely adds to his attractiveness to the psychological researcher. To ensure an accurate description of Bacon’s life, extensive data is examined using Alexander’s (1988) model of identifying salient themes. The study considers the nature and methodology of psychobiography, the theories of Jung, the life of Francis Bacon and then sythesises relevant material in a psychological profile. The findings of this study indicate that Bacon’s intense, creative and unorthodox life of genius fully justifies the research and provides an example of how a theory that is flexible can be an appropriate means of understanding complicated personalities. Jung’s description of the evolution of the personality allows for applicability and coherence, while at the same time accomodating even the most maverick of non-conventional lives.

- Description: The aim of this study was to describe and compare the gaze behaviour patterns of expert and near expert under 19 level rugby union players during one-on-one defensive play. Gaze characteristics such as the areas of interest visited, the number of fixations, the duration of each fixation, the starting and last fixations; and the order of fixations adopted were used to achieve the aim of the study. In addition, biographical data, including sporting and vision history, were collected. Data of the two groups were described and compared with statistically and practically significant differences been highlighted. Inferential statistics were used and the following significant levels set: p<.05 for t-tests and Chi-sq'ared - tests while Cohen's d (absolute value) ≥0.20 and Cramér‟s V ≥0.10 were used to determine the practical significance for statistically significant results, respectively. An exploratory and quasi-experimental design was used, in which 81 participants (16 – 19 years of age) were sampled for differences between experts' and near experts' visual-search strategies and gaze behaviour patterns when anticipating the direction of deceptive running skills in rugby union, however, only 68 participants had eye tracker data analyzed due to the strict calibration criteria. The expert players correctly anticipated significantly (t-stat = -3.16, p = .002, d = 0.71) more than the near expert players on average (75.76% compared to 66.46%), and therefore, were less susceptible to deceptive running skills. The near expert players were, however, more aware of their fixation location than expert players. Both expert and near expert players fixated considerably more on the knees and hips than any other area of interest, however expert players had fewer, but longer fixations than near expert players per run with 4.29 ± 1.89 fixations (χ2 = 3.90, p = .048, V = 0.24) of 0.420 ± 0.140 seconds (χ2 = 3.97, p = .046, V = 0.24) compared to 5.34 ± 2.39 fixations of 0.350 ± 0.150 seconds. Both the expert and near expert groups fixated more on the lower body than the upper body on average, however, the near expert players fixated significantly more off the body for all correct runs than the expert players (t-stat = 2.17, p = .034, d = 0.53). The expert players start fixating more on the knees at the start of each trial, whereas the near expert players start fixating more on the knees and hips, and considerably off-target. The expert players fixate significantly more on the knees (t-stat = -2.56, p = .013, d = 0.63) at the end of each trial than the near expert players on average, whereas the near expert players fixate more on the hips. The orders of fixation did not yield any discernable patterns between expert and near expert players for correctly anticipated runs. Experts exhibit superior visual-search strategies and gaze behaviour control, presumably using the top-down approach, to successfully anticipate an opponent's intended direction. This information could help coaches teach perceptual tackling skills to enhance motor learning and performance.

- Description: In this study a standardized 46 week chronic drinking water toxicity protocol was used to elucidate the toxic potential of Sutherlandia frutescens (S. frutescens) using histopathologic, morphometric and transmission electron microscopic analysis. The histopathologic changes in the duodenum, heart, kidney, liver, lung, pancreas and spleen of male Wistar rats were evaluated. Fifty-four rats were randomly divided into four groups: Group 1 – Normal diet control (ND control), n=7, Group 2 – Normal diet + plant extract (ND + p), n=9, Group 3 – High fat diet control (HFD control), n=19Group 4 – High fat diet + p (HFD + p), n=19In the high fat group male Wistar rats were fed ±55 g/day of a specialised high fat diet over a 46 week period to induce obesity and an insulin resistant state. The treatment groups (groups 2 and 4) received a dose concentration of a tea extract of the S. frutescens plant in their drinking water daily. This study showed that the consumption of S. frutescens significantly reduces weight gain in male Wistar rats on a chronic high fat diet (p≤0.001 vs. HFD control group). S. frutescens appears to propagate periportal and centrilobular glycogen storage in rat hepatocytes in the experimental groups as exemplified by a significantly (p≤0.0001 vs. control groups) increased incidences of Periodic Acid Schiff (PAS) positive staining S. frutescens also reduced intracellular lipid accumulation as made evident by the significantly lower incidence of epicardial adipose tissue (EAT), hepatic steatosis and pancreatic interstitial fat. Obesity was associated with increased fibrotic lesions such as myocardial perivascular fibrosis, centrilobular hepatic fibrosis and pancreatic periductal fibrosis. Obesity associated hypertension contributed to the widespread and significant increase in the average lesion severity of arterial congestion in all organs in the HFD control group. Pulmonary infection was equally prevalent in all rats. Despite the complex histopathology in all groups, differences in the control groups, such as, the presence of a conservative polymorphonuclear leukocyte (PMNL) infiltration, substantial intra-alveolar oedema and focal arterial wall hypertrophy in the control groups was highly suggestive of Sendai viral infection. However histopathologic evidence, in the treatment groups, suggested chronic recurrent viral infection with superimposed Mycoplasma pulmonis (M. pulmonis) bacterial infection. The impact of advanced suppurative pulmonary infection was widespread and exemplified by increased lesion incidences of spontaneous murine progressive cardiomyopathy (MCP) and spontaneous chronic progressive nephropathy (CPN) among others. In conclusion S. frutescens administered for 46 weeks to male Wistar rats significantly lowered intracellular lipid accumulation and obesity associated myocardial, renal, hepatobiliary, pulmonary and pancreatic histopathology. Moreover, duodenal, cardiovascular, hepatobiliary, pulmonary, renal, pancreatic and splenic tissue did not show histopathologic evidence of direct plant extract associated toxicity or carcinogenicity.

Despite the complex histopathology in all groups, differences in the control groups, such as, the presence of a conservative polymorphonuclear leukocyte (PMNL) infiltration, substantial intra-alveolar oedema and focal arterial wall hypertrophy in the control groups was highly suggestive of Sendai viral infection. However histopathologic evidence, in the treatment groups, suggested chronic recurrent viral infection with superimposed Mycoplasma pulmonis (M. pulmonis) bacterial infection. The impact of advanced suppurative pulmonary infection was widespread and exemplified by increased lesion incidences of spontaneous murine progressive cardiomyopathy (MCP) and spontaneous chronic progressive nephropathy (CPN) among others. In conclusion S. frutescens administered for 46 weeks to male Wistar rats significantly lowered intracellular lipid accumulation and obesity associated myocardial, renal, hepatobiliary, pulmonary and pancreatic histopathology. Moreover, duodenal, cardiovascular, hepatobiliary, pulmonary, renal, pancreatic and splenic tissue did not show histopathologic evidence of direct plant extract associated toxicity or carcinogenicity.
