In this issue of the African Journal of Nephrology (AJN Vol 18, No 1) we publish original articles ranging from the prevalence of chronic kidney disease in an African population in general, to the role of HIV in kidney disease. An elegant study of fractionated heparin use in haemodialysis is also presented. Continuous ambulatory peritoneal dialysis is an important modality of renal replacement to be considered in Africa in view of its ease of operation. However, beware of potential complications including sclerosing peritonitis as reported in Cape Town (South Africa).As in the past, this issue covers a wide variety of topics with contributions from diverse authors from south to west and North Africa. On behalf of the editorial board, I wish to take this opportunity to thank all of the authors and reviewers who have contributed to this issue of the journal, as well as to the readers for their sustained interest in the African Journal of Nephrology.

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.

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

Similar Decrease

A survey of the main papers published in the South African Journal of Physiotherapy over the past 10 years (1980 to 1989) was conducted to establish the trends in research methodology, subject topic and qualifications of the first authors. It was found that there is a significant increase in the number of experimental trials used and a similar decrease in the number of surveys conducted from the first to the second five-year periods (1980 to 1984 and 1985 to 1989). Statistical analyses of data were more often used in the second period. There is a marked increase in the number of articles on education/administration in the second period. In this period from 1985 to 1989, there are fewer first authors with a Diploma in Physiotherapy only, a medical degree or a technical qualification, while there are more first authors with postgraduate qualifications. These findings support the observation that there is a growing awareness of the need for a more scientific approach to Physiotherapy research.

A continuum survey of the galactic-centre region has been carried out at Parkes at 20 cm wavelength over the areal11= 355° to 5°,b11= -3° to +3° (Kerr and Sinclair 1966, 1967). This is a larger region than has been covered in such surveys in the past. The observations were done as declination scans.

Origin Of The Moon

During the last 10 years, the writer has presented evidence indicating that the Moon was captured by the Earth and that the large collisions with its surface occurred within a surprisingly short period of time. These observations have been a continuous preoccupation during the past years and some explanation that seemed physically possible and reasonably probable has been sought.
