Turning the lens on the adolescent suicide

De Monk, Ingrid Venessia January 2014 (has links)
In South Africa, suicidal behaviour in the younger generations has become rapidly part of a major public health problem. It is a well-known fact that adolescence is a critical period of progression in a teenager’s development which makes them more susceptible and vulnerable to suicide. Statistics have shown that there has been an increase in suicide among adolescents within the last decade (Schlebusch, 2005). The main aim of this research study is to explore the perceptions of adolescents regarding the factors that contribute to adolescent suicide. This study reviews literature concerning various risks factors for adolescent suicidality. It also described major social and psychological theories of suicide and the extent to which these studies support the importance to adolescent suicide. In the literature review theories of Bronfenbrenner’s Ecological Systems Theory, Durkheim’s sociological theory of suicide, Freud’s psychological perspective and Baumeister’s Escape Theory were discussed. A qualitative research design will be used by using visual participatory methodology techniques namely photo voice and reflective writing. A sample of 12 grade 11 learners, male and female, was purposely selected to participate in the research study. The focus of the study is to investigate the risk factors underlying adolescent suicidal behaviour in schools in the Northern Areas of Port Elizabeth, as well as to explore the stressors experienced by adolescents that could contribute to them having a higher suicide risk. Another focus point will be to look at prevention strategies as an antipode for suicidal behaviour. The main findings that emerged from the data analysis include contributing factors namely: socio-economic factors, personal factors, psychological factors and educational and school-related factors. The main prevention strategy themes emerged from findings derived from the data and include: parental involvement, religion, professional help and support groups and confiding in someone that you trust.

Collaborative research with traditional African health practitioners of the Nelson Mandela Metropole : antimicrobial, anticancer and anti-diabetic activities of five medicinal plants

Van Huyssteen, Mea January 2007 (has links)
The promotion and development of indigenous knowledge pertaining to the traditional African healing system is one of the prime objectives set out by the South African government. Despite excellent research opportunities and funding, the biggest problem with ethnopharmacological research is a lack of interaction with indigenous communities, which tends to dilute the benefits this research has to offer these communities. The primary aim of this study was thus to promote the traditional African healing system through collaborative medicinal plant research with local traditional health practitioners. The research collaboration aimed to validate some biological activities of traditional remedies used by collaborating traditional health practitioners and ensured interactive sessions where scientific literature, research practices, findings and relevant legislation were discussed and debated. The joint development of a medicinal garden was a valuable tool in realising these goals. Aqueous and ethanol extracts of Bulbine frutescens, Ornithogalum longibracteatum, Ruta graveolens, Tarchonanthus camphoratus and Tulbaghia violacea were selected for antimicrobial, anticancer and anti-diabetic screening, because of their sustainable utilisation potential. The ethanol extract of T. violacea produced the best antimicrobial activity on Bacillus subtilis (100% growth inhibition) and Candida albicans (89% growth inhibition) at 250 μg/ml. The EC50 for the ethanol extract of T. violacea against HT29 colon cancer cells was 101 μg/ml. The aqueous extracts of B. frutescens and T. camphoratus (0.5 and 50 μg/ml) produced the highest overall glucose uptake activity in Chang liver and C2C12 muscle cells. T. camphoratus was unanimously chosen by participating practitioners as the plant to be investigated further. The aqueous extract of T. camphoratus increased glucose uptake in C2C12 muscle cells through increased translocation of GLUT4 to the plasma membrane and activation of the PI3-kinase and AMP-kinase pathways. It produced some alpha-glucosidase inhibitory activity at concentrations of ≥ 200 μg/ml. Apart from interactive feedback seminars at which the findings were presented to participating practitioners, all scientific literature regarding the plants was summarised, translated, compiled and given to participating practitioners in written format. An indigenous knowledge agreement has been negotiated and will formalise the collaboration in future. It is recommended that future research focuses on plants with economic development potential that can be cultivated in the medicinal garden.

Attitudes towards hunting amongst the economically active public in Port Elizabeth

Coetzer, Wentzel Christoffel January 2010 (has links)
Wildlife ranching is recognized as one of the important agricultural industries in South Africa, with hunting being the primary segment of the game industry. Hunting is an essential part of wildlife management and it contributes significantly to the conservation of biodiversity and to the economy. Despite this, the social acceptability of hunting is often questioned and negative attitudes towards hunting within the larger society may become a potential threat to the hunting industry. This may jeopardize the effective management of game and have a negative impact on conservation and the economy. This study is an empirical investigation of the attitudes of the economically active public in Port Elizabeth towards hunting. The objectives of this study are to investigate the nature and extent of the public's attitudes towards hunting, as well as to identify factors influencing the public's attitudes towards hunting. The study commenced with the establishment of a theoretical framework, based on a literature study on the psychology of human perceptions and attitudes towards hunting. The theoretical framework was then used to develop the empirical component of the study. A survey was conducted amongst a statistically representative sample of the economically active public in Port Elizabeth during 2009. The data was collected by means of personal interviews and self-administered questionnaires were used as the survey instrument. The study found that the economically active public in Port Elizabeth generally holds favourable attitudes towards hunting, with only a small proportion of the population wanting to ban hunting. The belief that hunting endangers wildlife was the most prominent reason for opposing hunting. Negative attitudes towards hunting were largely based on incorrect beliefs regarding hunting. The extent of a person's knowledge of hunting and exposure to hunting, as well as a person's social ties had a significant influence on their attitudes towards hunting.

Assessment of drug resistant Tuberculosis and Human Immunodeficiency Virus and Acquired Immunodeficiency Syndrome: knowledge levels among community members in Nelson Mandela Metropolitan Municipality

Fana, Thanduxolo January 2013 (has links)
The aim of this study was to assess community members’ knowledge levels regarding Drug Resistant TB and HIV and AIDS. The study was conducted at ward 40 in Green bushes area in Nelson Mandela Metropolitan Municipality (NMMM). A quantitative research method was used in this study. Random sampling is the type of probability sampling method that was used in this study. The sample consisted of 100 respondents above 18 years who were randomly selected from the beneficiary list of for the RDP houses in Green bushes area in the Nelson Mandela Metropolitan Municipality. Data for this study were collected using close ended questions which were administered by the researcher to the selected participants. Data was analysed using bivariate and descriptive statistics according to the identified themes. The study revealed that community members had high knowledge levels regarding Drug Resistant TB and HIV and AIDS prevention, transmission modes and diagnosis and treatment methods. The findings revealed that community members were highly knowledgeable and aware of the fact that abstaining and practising safe sex were means of preventing the spread of HIV and AIDS as it was spread through unprotected sex, while opening of windows and minimisation of close contact with HIV positive people and children with people infected with Drug Resistant TB are infection control measures or methods of preventing the spread of the disease. Additionally, the study indicated that female respondents were more aware and knowledgeable about prevention, transmission modes and diagnosis and treatment of Drug Resistant TB and HIV and AIDS than male respondents. Furthermore, the findings revealed that the respondents were highly knowledgeable and aware about transmission of Drug Resistant TB and HIV and AIDS; knowledgeable about prevention and less knowledgeable about diagnosis and treatment. A high percentage of female respondents knew that there was no vaccine to neither prevent nor cure HIV and AIDS and that antiretroviral drug were used to manage it. The study also showed that female respondents knew that all people irrespective of race and economic class can be infected with Drug Resistant TB and HIV and AIDS. It is important to note that the respondents between 41-60 years possessed more knowledge regarding Drug Resistant TB and HIV and AIDS than the respondents who were between 18-40 years. Lastly, the study showed that there were significant differences in gender and knowledge and no significant differences in age and knowledge of the respondents regarding Drug Resistant TB and HIV and AIDS. It is recommended that in future, research regarding knowledge levels about Drug Resistant TB and HIV and AIDS be extended to other wards in the Nelson Mandela Metropolitan Municipality (NMMM). Accurate knowledge should be provided by ensuring that educational materials that are developed, are appropriate for the various levels of literacy, and that more appropriate and relevant information regarding these diseases is made more accessible to community members in their home languages. The researcher further recommends that during training interventions and educational campaigns more emphasis should be put on prevention, diagnosis and treatment of Drug Resistant TB and HIV and AIDS.

Assessing the entrepreneurial attributes of undergraduate business students at Nelson Mandela Metropolitan University

Saunders, Shelley January 2013 (has links)
To improve and develop South Africa’s entrepreneurial activity, it is vital that the population acquires certain attributes which are common among individuals who exhibit entrepreneurial behaviour. As the occurrence of entrepreneurial attributes increases in the population, so too will the probability of entrepreneurial behaviour and entrepreneurial activity. A possible first step in ensuring that a population possesses the necessary attributes is to assess the current levels of development of these entrepreneurial attributes among students of business. Underdeveloped attributes can then be identified, and steps taken to bring about improvements. The primary objective of this study was to assess the entrepreneurial attributes of undergraduate business students at the Nelson Mandela Metropolitan University. In order to achieve this objective an in-depth analysis of secondary sources was conducted. The nature of entrepreneurship was defined and its importance highlighted. Furthermore, the status of entrepreneurship both globally and nationally was elaborated on. Entrepreneurship education was also addressed, and its role in developing entrepreneurial attributes was discussed. The 16 entrepreneurial attributes associated with successful entrepreneurs were described. The most commonly used intentions-based models were also discussed. In line with the intentions-based theories, the greater the perception of possessing the attributes associated with a successful entrepreneur by an individual, the greater the belief by that individual that he or she has the capacity and competence to become an entrepreneur, which in turn will influence their entrepreneurial intentions. Against the background of the literature overview, several hypotheses were formulated and subjected to empirical testing. A quantitative research approach was selected, the sample consisting of all undergraduate business students studying at three South African universities as well as two international universities. Convenience sampling was implemented in this study. The validity of the measuring instrument was determined by means of a factor analysis, and the reliability by means of calculating Cronbach alpha coefficients. The statistical techniques used to analyse the data included calculating descriptive statistics (the mean, standard deviation and frequency distributions), t-tests and Cohen’s d, a multivariate analysis of variance (MANOVA), an analysis of variance (ANOVA), Chi-squared statistic, and Cramer’s V. The results of the study show that NMMU students regarded the attributes Commitment, High energy level, Planning and perseverance and Overcoming failure as the four most-developed attributes, while they regarded Continuous learning, Knowledge-seeking, Initiative and responsibility and Communication ability as the least-developed. With the exception of the attributes Commitment and Overcoming failure, the level of development of the entrepreneurial attributes of NMMU students showed significant improvement between the 2001 and the 2010 studies. With the exception of Continuous learning, no significant differences were reported in the levels of development of the various entrepreneurial attributes between students at NMMU and students at the other South African universities participating in the study. When comparing the significant differences in the level of development of the 16 entrepreneurial attributes between NMMU and the international universities, a large practical significance was found for the attributes High energy level, Continuous learning and Knowledge seeking. For the attributes Planning and perseverance, Communication ability, Overcoming failure, Initiative and responsibility, High energy level, Creativity and flexibility, Knowledge seeking, Continuous learning, Financial proficiency and Business knowledge, students with entrepreneurial intentions reported significantly higher mean scores than students without entrepreneurial intentions. In other words, students with higher levels of development of these attributes are more likely to have entrepreneurial intentions. It was also found that significant differences in the levels of development of entrepreneurial attributes were reported for the demographic variables Levels of study, Gender and Age. No significant differences were found to exist between the demographic variables Level of study, Gender and Self-employment status of parents and the Entrepreneurial intention of NMMU students. This study has contributed to the field of entrepreneurship research by identifying several entrepreneurial attributes that are more likely to be found in students with entrepreneurial intentions than those without them. This study has also shown that certain demographic factors are related to the levels of development of certain entrepreneurial attributes, as well as to entrepreneurial intentions. Furthermore, through the assessment of entrepreneurial attributes of NMMU students and by making comparisons with other universities, this study has contributed to entrepreneurship education at NMMU as well as to entrepreneurship education in South Africa and abroad. Educators of entrepreneurship have been given insights into the levels of development of several entrepreneurial attributes among their students. In addition, recommendations have been made on how to improve the levels of development of the attributes investigated in this study.

Breaking down subtle and implicit racial divides in higher education institutions : an educational management perspective

Toni, Mademoiselle Noluthando January 2009 (has links)
This thesis examined the manifestations of the various forms of racism in a South African institution of higher learning, the Nelson Mandela Metropolitan University (NMMU). The study further attempted to confront racism from the perspective of finding ways in which human relations of a diversified higher education population could be improved. As the issue at hand in this study relates to racism, critical race theory (CRT) was explored in an attempt to understand different perceptions and ways of dealing with racial inequality. CRT recognizes the complexities of racism and the construction of race as a way of justifying political, economic and social inequality (Stovall, 2006:247). This understanding played a role in making sense of perceived racial discrimination which is also connected to gender, age and social class. CRT conceptual tools, such as stories and counter stories featured strongly in the data collection process. Understanding the relationships of power, race and racism, as advocated by CRT, was vital in the process of analyzing data, reporting on the findings, and the proposed recommendations. The empirical data and literature provided insight in the design of a ‘Wheel of Humanity’ which serves as a succinct portrayal of ideas that can work in nurturing acceptable, to better, human relations. The study revealed that Meta-stereotypes influenced the perceptions of racist attitudes, behaviours and practices. As much as overt forms of racism were reported as minimal, subtle and implicit forms still exist, and are aggravated by the ‘culture of power’ that is taken for granted. The success of initiatives designed for the purposes of going beyond race, and adopting a humane approach in instilling the principles of ubuntu, depends on changing attitudes and preconceived ideas.

The use of Geographical Information Systems for the promotion of spatial cognition, spatial perspective taking and problem solving in school level geography

Britz, Hendrina Wilhemina January 2013 (has links)
A question asked at the United States of America (USA) National Council for Geographic Education (NCGE) conference in 1967, namely, what learning does GIS allow that other ways do not and whether teaching GIS at school level is worth the time and effort required to implement it, remains largely unanswered. Literature searches suggest that little more has been done since 1967 to investigate the effectiveness of GIS in education, or that there are any findings to suggest that GIS is worth the time and effort to implement in schools. Internationally the implementation of GIS software and geo-spatial data in schools has been slow, and South Africa is no exception. The main reasons given for slow implementation internationally have included lack of resources, lack of training and lack of time. The majority of secondary schools that offer Geography in the Port Elizabeth Education District, South Africa, teach GIS theory without the use of GIS software and geo-spatial data. The purpose of this research was to elicit the perceptions of secondary school level Geography teachers and learners of the benefits, barriers and obstacles to implementing GIS software and geo-spatial data as a teaching strategy. As a focused exercise to investigate what learning using GIS allows that other ways do not, this study also investigated whether using GIS as a teaching and learning strategy enables the promotion of learners spatial cognition, spatial perspective taking and problem solving abilities better than traditional methods do. The findings are viewed through the lens of developing Crystallized Intelligence (Gc), Spatial Intelligence (Gv) and Fluid Intelligence (Gf), respectively. The study followed a concurrent transformative mixed methods design with pre-post testing and the use of crossover experimental and control groups to generate both qualitative and quantitative data. Questionnaires aimed at all secondary Geography teachers in the Port Elizabeth Education District were used to assess how GIS is taught in their schools and to evaluate their perceptions of the benefits and barriers of implementing GIS software and geo-spatial data in the classroom. Four secondary school Geography teachers in four schools volunteered to take part in the experimental aspects of the study. Empirical data on the development of spatial cognition, spatial perspective taking, and problem solving were generated via pre- and post-tests in which the grade 11 Geography learners participated. Experimental and comparison groups of learners wrote four different types of pre- and post-tests where the experimental groups worked on GIS software with geo-spatial data while the comparison groups used traditional methods. Teacher interviews and learner interviews were also conducted to assess attitudes towards GIS software and geo-spatial data as a teaching strategy. The results from this aspect of the study mirrored the benefits and barriers to implementing GIS in schools recorded in international literature. However, and possibly more importantly, the empirical data generated by the learners revealed that GIS software and geo-spatial data do statistically significantly promote better spatial cognition (Crystallized Intelligence) and spatial perspective taking (Spatial Intelligence) than traditional methods do (i.e. using atlases, rulers and calculators). No improvement was found in the experimental groups‟ problem solving abilities. This report offers possible explanations and recommendations in terms of socio-cultural findings from other educational studies on the effects of exploratory talk on the development of Fluid Intelligence. Recommendations are made for the attention of curriculum developers, teachers, school principals, departmental officials and other educational stakeholders in terms of what is required for the successful implementation of GIS software and the use of geo-spatial data in secondary school Geography classes.

Changes in the anthropometric, physical and motor characteristics of elite soccer players aged 15 to 18 years within a training year

Baatjes, Sherman Gerard January 2006 (has links)
The primary aim of this study was to investigate the seasonal changes that occur in the anthropometric, physical and motor characteristics of elite junior soccer players over the course of a training year. The participants targeted were elite soccer players from the NMMU-FCK Soccer School of Excellence and a total of 18 players between the ages of 15 to 18 years were recruited to comprise the sample for the study. The participants in the sample were assessed on four separate occasions. Each testing period was separated by a three month interval with the first testing period taking place in June 2005, at the start of their pre-season period, and the last testing session taking place in March of the following year, at the end of their playing season. In order to determine which specific characteristics of soccer were to be tested, the relevant literature was reviewed to establish the requirements, attributes and indicators of success in elite soccer. Therefore the test battery used was compiled in an attempt to address each of the identified physical attributes that contributes to successful soccer play. The battery included the following tests: weight, height and percentage body fat to represent the anthropometric characteristics. The physical characteristics were assessed by testing flexibility, anaerobic speed endurance, aerobic endurance, and muscular strength tests (1 RM bench and leg press, grip strength, and isokinetic knee strength). The motor assessments comprised of tests for speed (10-m, 20-m, and 40-m), explosive leg power (vertical jump), agility, and soccer-specific tests (dribbling and shooting at goal). In addition maturity status during the study was assessed using grip strength and height scores. All of the participants within the study sample were assessed on each day of the testing period, in alphabetical order, and this order was maintained during each testing period. Each of the four testing sessions lasted three days. On entering the Nelson Mandela Metropolitan University-Biokinetics and Sport Science Centre (NMMU-BSSC) laboratory on day 1, the participants completed the test battery in the following order: anthropometric measurements (weight, height, skinfolds), flexibility test (sit and reach), leg power test (vertical jump), muscular strength tests (1RM bench press, 1RM leg press, grip strength), and an aerobic endurance test (Multi-Stage Shuttle Run). The tests conducted on day 2 of the test battery were conducted as field tests at the NMMU-FCK soccer playing fields and the participants completed the tests in the same alphabetical order as day 1. The testing battery was conducted in the following order: speed tests (10m, 20m, and 40m sprinting), agility test (Illinois agility run), soccer-specific tests (dribbling and accuracy tests), speed endurance test (Yo-Yo intermittent recovery test). Testing on day 3 consisted of Isokinetic dynamometry strength testing and was conducted at the NMMU-BSSC. Each participant completed the testing protocol according to the same alphabetical order as was used on days 1 and 2. In order to achieve the aim of the study, the following objectives were set: to determine the anthropometric, physical and motor characteristics of the participants at the pre-season, start of season, mid-season and end of season stages of the training year and to identify the peak scores achieved for each variable tested; to compare the variables tested at each of the four testing sessions to determine the progression of each variable tested and to identify at which testing session peak performance related fitness was achieved; to compare the results obtained with relevant data from other research literature; and to monitor the maturation status of the participants. Based on the results achieved it can be concluded that the participants achieved peak physical fitness at the mid-season period (testing session 3). It would appear that the attainment of these results was determined by the participants being exposed to both a pre-season and an in-season training period. It seems that both the completion of the specific types of training that occurred during these two periods, as well as the competitive matches played, elevated the participants physical fitness to the levels required for success at the elite level.

Fundamental movement skill proficiency status of girls aged 9-to-12 years from previously disadvantaged communities in Nelson Mandela Bay

Kahts, Samantha Andrea January 2014 (has links)
A lack of fundamental movement skill (FMS) proficiency in children can contribute to decreased physical activity (PA) levels, increased adiposity and poor acquisition of specialised sport specific movement skills. To prevent the latter, the identification of FMS status in early and middle childhood years is needed for targeted and specific interventions. Against the backdrop of physical education being omitted from the South African school curriculum, the presence of a patriarchal society, gender sporting stereotyping, high levels of unemployment and low education levels; the assessment of FMS status is particularly warranted. Aim of Study: The primary aim of this study was to assess the FMS proficiency of girls aged 9-to-12 years from previously disadvantaged communities within Nelson Mandela Bay. Methodology:A descriptive-exploratory-contextual study design, employing quantitative assessment techniques, was utilized. The sample comprised of 227 girls. Convenience sampling was employed. Testing consisted of FMS proficiency tests in the 20m and 40m sprint, standing long jump, throwing for distance, catching, static balance and throwing for accuracy. FMS process scores were assessed with the body component (BC) and Test of Gross Motor Development II (TGMD II) approaches. Anthropometric measurements of the standing and seated height, mass, arm span and leg length were additionally measured. Microsoft Excel® and Statistica® were used for descriptive and inferential statistical analysis. In the case of significant ANOVA results, the Scheffe post hoc test was used for pairwise comparisons. Statistical significance was set at p<.05 and practical significance (Cohen’s d) was set at d>.2. Pearson Correlation Coefficient identified statistical and practical correlations between two variables and chi square was applied to indicate differences in frequency distribution tables. Cramer’s V values were applied to determine practical significance in the case where statistical significant differences were identified between sets of frequency distributions.

Development of an integration model for the transport operators in the Nelson Mandela Bay area

Pienaar, Jacques Ludolph January 2008 (has links)
This research paper focuses on developing a model for the integration of the transport operators in the Nelson Mandela Bay area. The motivation for this integration is the Nelson Mandela Bay Municipality’s Public Transport Plan, which has set the goal of developing a new public transport system for the Metropolitan area. This system will integrate the different modes of transport into a single, seamless and scheduled service which will adhere to contractually enforced levels of quality, reliability and safety. In order to achieve this vision, the current bus and taxi operators will need to be unified into a viable and operational entity structure which will provide the required services to the public. The main research problem has therefore been identified as follows: How can the bus and taxi operators in Nelson Mandela Bay be integrated into a single entity, or small number of entities, in order to provide a viable, efficient and sustainable public transport service? This research paper sought to address this problem by conducting a case study of the Nelson Mandela Bay project, which took place over the course of a one year period. The author served as the project manager on the team that was responsible for developing the integration model. Additional research included a study visit to the cities of Bogota and Pereira in Colombia, which have implemented similar transport models, as well as a secondary study focusing on generic organisational integration strategies in existing literature. This paper is fundamentally a qualitative study. In this light, the research data was analysed according to the quasi-judicial method, which was deemed most suitable to the case study format adopted. The findings of the analysis were evaluated, and based on the resultant conclusions, a final integration model was recommended. The fact that this study is based on an actual project that has real world implications and consequences makes the result very relevant, and as such it will serve as a valuable addition to the body of knowledge which can be of assistance to other cities or project teams facing similar challenges in South Africa or even internationally.
