Objective. To summarise the results of the past 8 years obtained at the South African Doping Control Laboratory and to compare the results with international statistics. Method. Screening procedures were performed on 14 017 urine samples collected from competitors in 54 different sporting codes during the period 1995 - 2002. Samples were analysed using gas chromatography and gas chromatography/mass spectrometry for the presence of prohibited substances, which are listed by the International Olympic Committee (IOC). Results. The results obtained were compared with those of the IOC-accredited laboratories. Prohibited substances were detected in 300 samples (2.14%), of which 45.6% contained anabolic agents and 34.6% stimulants. The positive samples from the IOC laboratories contained 58.7% anabolic agents and 20.8% stimulants. Testosterone and nandrolone were the anabolic agents most frequently detected in positive samples, both in South Africa and internationally. The ephedrines as a group accounted for most stimulants detected in positive samples. Conclusion. It is of concern that the percentage of positive samples (2.14%) obtained in our laboratory is higher than the 1.70% in IOC laboratories. It is therefore necessary that doping control to curb the use of prohibited substances should continue and expand. South African Journal of Sports Medicine Vol.16(1) 2004: 29-32

This article analysed 15 years, from 1996 to 2010, of research published in the three leading South African business management journals. The three journals chosen were the South African Journal of Business Management, the South African Journal of Economic and Management Sciences and Management Dynamics. Content analysis was used to compare five broad themes in the journals: firstly the nature of authorship was examined, and then the most published as well as most prolific authors were identified. Thirdly, the most prominent universities and departments were identified whereafter the research themes and disciplines of the articles and authors were analysed. Lastly, various manuscript characteristics were investigated. This article provides a clear picture of the evolution of South African management literature over the past fifteen years.

Objectives. Studies have shown the existence of a significant home ground advantage in a range of sports. The aim of this study was to determine whether home performances of the South African teams during the 1996 - 2005 seasons were different before touring to Australia and New Zealand, compared with the home matches played after the 4 - 5-week tour. The question was relevant because this competition places unusual demands on the players. For example, the duration of the tournament is 12 weeks, during which time the South African teams travel across 37.3 ± 2.5 time zones as they play 11 matches. Therefore, any home ground advantage may be negated by travel fatigue. Outcome measures. The mean points difference was calculated for home fixtures for four South African teams both prior to and following touring during the competitions from 1996 to 2005. Play‑off matches were excluded from analysis. Performance was defined as a positive points difference (points difference = points ‘for' minus points ‘against'). Results. The first finding of the study was that a home ground advantage did indeed exist for all the teams during the tournament (points difference of 6.6 ± 17.4 (N = 664 matches) home vs. -6.8 ± 17.3 points away (N = 656 matches) (p < 0.05). There was no difference between the mean ‘home' points difference for all the South African rugby teams either before (1.9 points, N = 96 matches) or after (2.3 points, N = 107 matches) touring overseas in the Super 12 competition.
