- Description: The primary aim of this study was to compare the Index of Coordination (IdC) for both sprint and endurance swimming and running of less-skilled level triathletes. The researchutilised a quantitative approach, specifically exploratory, with a one group post-test-only research design. Twenty participants from the triathlon community, ages 18 years and older, were selected via purposive and convenient sampling. The participants were expected to complete a total of four physical tests, namely 50 m sprint swim, 1500 m endurance swim, 50 m sprint run,and 5000 m endurance run, on four separate days, over a period of two weeks. The data was collected by video recording each participant performing each of the four different tests andcoded frame-by-frame onDartfish Video Solution (10.0).The IdCwas derived by identifying the time-in markers and time-out markers for both left and right arms when swimming; and by identifying the time-on markers and time-off markers for both left and right legs when running. The results revealed significant differencesbetweenthe IdCvalues ofsprint swimming and endurance swimming(p<0.001); sprint running andendurance running(p<0.001); sprint swimming andsprint running(p<0.001); andendurance swimmingandendurance running(p<0.001).The top performersin each testwere significantly faster than bottom performers(sprint swimming: p<0.001; sprint running:p<0.001; endurance swimming: p<0.001; endurance running: p<0.001) but no significant group differences on associated IdC were found(sprint swimming: p=0.535; sprint running: p=0.857; endurance swimming: p=0.132; endurance running: p=0.775).Bothendurance tests were divided into three equal portions and it was found that 23% ofthe fastest trial endurance swim time can be explained by the IdC obtained in portion three(p=0.032); and that 62% of the fastest trial endurance run time can be explained by the IdC obtained in portion one(p<0.001). The overall findings of the study suggest that an IdC mode is considered efficient relative to the environmental contextand thatIdCis relative to skill level or alternatively independent of performance times. The IdC, therefore, remains inconclusive as an alternative method but warrants further investigation particularly in longer distance endurance events.

- Description: With the changing landscape in South Africa to a full democracy, increased research has been undertaken in the psychometric field on local and national normative studies regarding various assessment measures. The Raven’s Coloured Progressive Matrices (CPM) is one of the measures that have already been extensively normed throughout the world for various population groups. In South Africa, local norms for normal populations of children have been developed by groups of researchers in the Grahamstown (Eastern Cape) as well as the Bloemfontein (Free State) areas. With a South African school educational system that focuses on Inclusive Education, there is a growing need for mainstream schools to identify learners who are at risk for learning disabilities in order to develop appropriate supportive intervention plans. The research aimed to establish psychometric normative screening data based on the Raven’s CPM, and to compare these with the established and published international and local Raven’s CPM norms. In addition, the researcher developed pilot classification scores for the early screening and detection of at risk learners in order to encourage the potential role and use of the Raven’s CPM in the identification of cognitive learning barriers. The sample consisted of 388 primary school learners identified as having cognitive barriers to learning. Archival data was used that was gathered from a Psychological clinic that provided screening services to schools in the Nelson Mandela Metropolitan area. The results of the study indicated that there was a proportional relationship between age and test performance. Gender differences were found where the males in this study outperformed the females. There was a significant difference in the Raven’s CPM test performance with respect to the grade levels of the learners. The study developed a special set of norms with cognitive classification scores that will aid in the early identification of learning disabilities.

- Description: Increasing competition within the freight transportation market in South Africa has intensified the need for rail industries to identify ways in which to enhance their competitiveness within this market. One of the most important challenges for organisations’ operating in this market is to deliver goods on time, while meeting the needs of customers, at the lowest possible cost. If such organisations are to remain competitive, it may be required of them to shift their focus to their employees. Research has shown that employees render organisations’ with sustainable competitive advantage, more specifically, it has shown that engaged employees surpass disengaged employees. The distinguishing factor for organisations’ in the search of competitive advantage would therefore be an engaged workforce. The primary research objective of this study was to investigate contribution of reward systems to enhanced employee engagement within Transnet Engineering (TE) in Swartkops, Port Elizabeth. A theoretical overview was conducted to evaluate different definitions, engagement theories and factors of reward systems which contribute to enhanced employee engagement. An empirical study was conducted by means of a survey with a questionnaire as data collecting tool. The purpose of the structured questionnaire was to validate the findings obtained from the theoretical overview and to assess employees’ perceptions of reward systems and engagement. Recommendations were made based on the findings of the literature and empirical study. These recommendations will assist the organisation in understanding how reward systems can be used to enhance employee engagement, so that a competitive advantage can be achieved within the freight transportation market.

- Description: Data envelopment analysis (DEA) is used to assess the efficiency of 15 container terminals in Africa. The models proposed by Charnes, Cooper and Rhodes (1978) and Banker, Charnes and Cooper (1984) are used to determine and rank the efficiencies of the container terminals for 2013 and 2014. The results show that selected South African container terminals can improve on their operations relative to some of their neighbours to the North. Bootstrapping methods are used to investigate and clarify the results. The Malmquist Productivity Index (MPI) model is used to track and explain changes in efficiency over the period of assessment.

- Description: A challenge facing higher education institutions is the level of technological entrepreneurship of first-year students in the field of technological programmes. This challenge has put pressure on management of higher education institutions to introduce an entrepreneurial mindset and encourage innovation. According to Development Policy Research Unit (2007:18), 23 percent of students choose qualifications mainly for the employment opportunities. According to Shein, Crous, and Schepers (2010:1), not only in growing economies such as South Africa‟s, entrepreneurship contributes to a national growth and contributes to job creation. Shein, et al. (2010:1), further claim that recent studies have shown a shift towards studying entrepreneurship in an attempt to uncover its fundamentals and its importance in adding to the well-being of the country.

- Description: The general aim of the study was to explore and describe community development workers` perceptions of wellness at an HIV/AIDS organisation in Nelson Mandela Bay, South Africa. The population of 36 community development workers at the Nelson Mandela Bay office of this organisation participated in this study. The sampling technique employed can be described as a census as it involved sampling an entire finite population that included all community development workers in the organisation. These workers are predominantly Xhosa-speaking adults between the ages of 21 and 60 years, and include both males and females. Qualitative data were gathered by means of audio-recorded focus groups, utilising semi-structured interviews. Tesch`s method was used to analyse the data, while Guba`s guidelines were used to enhance the trustworthiness of the research. Focus group interviews with community development workers revealed seven common themes in the experience of working in the HIV/AIDS organisation: (a) participants’ understanding of wellness; (b) organisational factors that impact on wellness; (c) personal factors that impact on wellness; (d) family and community factors that impact on wellness; (e) participants’ wellness; (f) personal coping strategies; and (g) suggestions regarding organisational strategies to enhance employee wellness. It is envisaged that the research findings of this study will be used in future to direct interventions that will be beneficial for the short and long term planning for the wellness of the community development workers of the HIV/AIDS organisation and those around them. It was recommended that the organisation was to develop a workplace wellness programme, increase management support towards the staff wellness and to increase the staff capacity.

- Description: The purpose of this research was to investigate the effectiveness of IQMS amongst teachers in the Butterworth district. Using a convenient sample of 79 senior secondary school teachers, a survey research design was used to collect both quantitative as well as qualitative data on the effectiveness of IQMS. The formulation of statements on the effectiveness of IQMS was informed by the levels of effectiveness of the Kirkpatrick’s model. A likert scale was used to rate the effectiveness of IQMS with respect to teachers’ views on the various statements that sought to measure the effectiveness of IQMS. The narratives of teachers on the SWOT analyses constituted qualitative data which was used to corroborate and contradict trends from the quantitative findings. Thus, SWOT analysis results were used to validate quantitative findings. In analysing quantitative data, descriptive statistics were employed to look at the distribution of the responses and overall trends. Significant differences in terms of gender, age, employment status, length of service, and the highest tertiary qualification were computed by the SPSS software. The SWOT analyses results from the open-ended questions were analysed through extraction of themes, categories and patterns. The quantitative findings suggested that IQMS is an effective evaluation instrument though the qualitative SWOT analyses results suggested otherwise. The study’s findings highlighted areas where IQMS is potentially effective, areas where there are challenges in the implementation of IQMS, and niches for intervention. The study has implications for IQMS policy and programme administrators in the district offices, school principals and teachers in the school sites, as well as implications for further research.

- Description: Self-efficacy is considered to be a significant variable for enhancing all aspects of human performance (Druckman, 2004). Social support may influence self-efficacy through each of the four channels of self-efficacy information which consist of performance accomplishments, vicarious experience, verbal persuasion and physiological responses (Bandura, 1997). The primary aim of this study was to explore and describe the nature of change that occurred in selfefficacy and received social support of university-age academy cricketers over the duration of an academy programme. The secondary aim was to explore and describe the relationship between the two constructs, self-efficacy and social support. Sixty-five male, university-age (18-25 years) provincial academy cricketers completed a social support measure and a self-efficacy measure specifically designed for the purposes of this study. These measures were based on Rees and Freeman’s (2007) items and Cox, Martens and Russell’s (2003) revised Competitive State Anxiety Inventory-2 (CSAI-2 - Martens, Burton, Vealey, Bump & Smith, 1990) respectively. The perceived pre- and post-academy personal ratings of self-efficacy and social support, obtained prior to the start of the South African Interprovincial Academy Cricket week, referred to participants’ perceptions before and after attending their respective provincial academies. An inferential pre-experimental post-pretest design was used. The results included significant changes found in self-efficacy, esteem social support, informational social support and tangible social support over the academy season. There were no differences attributed to the length of time a cricketer had spent at the academy or to the cricketer’s highest level of achievement in cricket. The only significant correlation that existed between self-efficacy and social support was the correlation between self-efficacy and x informational social support. This study provided an initial insight into the role of self-efficacy and social support in talented cricketers, especially in a South African context.
