UNIVERSITEIT VAN STELLENBOSCH UNIVERSITY OF STELLENBOSCH NAVORSINGSVERSLAG RESEARCH REPORT 2003 Redakteur / Editor: PS Steyn Senior Direkteur: Navorsing / Senior Director: Research Universiteit van Stellenbosch / Stellenbosch University Matieland 7602 ISBN 0-7972-1083-0 i VOORWOORD Die Navorsingsverslag van 2003 bied 'n omvattende rekord van die navorsingsuitsette wat aan die Universiteit gelewer is. Benewens hierdie oorkoepelende verslag oor navorsing word jaar- liks ook ander perspektiewe op navorsing in fakulteitspublikasies aangebied. Statistieke om- trent navorsingsuitsette word in ander publikasies van die Universiteit se Afdeling Navorsings- ontwikkeling aangegee. Die Universiteit se navorsingspoging is, soos in die verlede, gesteun deur 'n verskeidenheid van persone en organisasies binne sowel as buite die Universiteit. Die US spreek sy besondere dank uit teenoor die statutêre navorsingsrade en kommissies, staatsdepartemente, sakeonder- nemings, stigtings en private indiwidue vir volgehoue ondersteuning in dié verband. Wat die befondsing van navorsing betref, word navorsers aan Suid-Afrikaanse universiteite – soos elders in die wêreld – toenemend afhanklik van nuwe bronne vir die finansiering van navorsing. Dit sluit beide nasionale en internasionale befondsingsgeleenthede in. Die Universi- teit van Stellenbosch heg daarom groot waarde aan streeksamewerking en aan betekenisvolle wetenskaplike ooreenkomste met ander universiteite in Suid-Afrika en in die buiteland, asook aan die bilaterale navorsings- en ontwikkelingsooreenkomste tussen Suid-Afrika en ander lande. Benewens die aktiewe ondersteuning van navorsing deur die bestuur van die Universiteit, word ’n verskeidenheid van dienste aan die navorsersgemeenskap gebied. Dit sluit onder andere biblioteek- en inligtingsdienste, informasietegnologie, die instandhouding van laboratoria en toerusting en die administratiewe en finansiële infrastruktuur in, waarsonder navorsing nie gedoen kan word nie. Die toewyding en voortreflike bydraes van die US-personeel wat al die navorsingsuitsette moontlik maak, word ook met groot waardering erken. Baie dankie aan die personeel van akademiese departemente vir die invoer van data in die stelsel, asook aan die personeellede van die Afdeling Navorsingsontwikkeling wat gemoeid was met die voorbereiding van hierdie verslag. 'n Spesiale woord van dank gaan aan me Lindie le Roux wat op bekwame wyse die tegniese versorging, uitleg en afronding van die verslag waargeneem het. Prof Piet Steyn Senior Direkteur: Navorsing Julie 2005 ii FOREWORD The Research Report of 2003 provides a comprehensive record of the University's research outputs. In addition to this overall survey of research at the institution perspectives are provided in publications by individual faculties. Statistical perspectives on research output are presented in other publications of the University's Division of Research Development. As in the past, a variety of persons and organizations both inside and outside the University contributed to the University's research programme. The US wishes to express particular thanks to the statutory research councils and commissions, government departments, industrial enterprises, foundations and private individuals for their continued support in this regard. As far as research funding is concerned, researchers at South African universities are – as elsewhere in the world – increasingly dependent upon new sources for research funding. This includes national and international opportunities alike. Stellenbosch University therefore attaches great value to regional cooperation and substantive scientific agreements with other universities in South Africa and abroad, and to bilateral research and development agreements between South Africa and other countries. Apart from the active support of research by the University's management, a variety of internal support services provide assistance to researchers. These include the library and information support services, information technology, the maintenance of laboratories and equipment and the administrative and financial infrastructure, without which it would be impossible to conduct research. We acknowledge the dedication and excellent contributions made by Stellenbosch University staff members to the research output with much appreciation. Thanks are due to the staff of the academic departments for the input of data into the system, and to the staff members of the Division of Research Development involved in preparation of the Report. A special vote of thanks is due to Ms Lindie le Roux for her expert handling of the final outlay and editing of the Report.
