Gender differences in the publication productivity of South African scientists

[摘要] ENGLISH ABSTRACT: This dissertation is aimed at describing gender difference in publication productivity among South African academic authors, and to develop an understanding of possible reasons for these differences. It is argued that the lack of empirical knowledge of publication productivity of academics in South Africa needs to be addressed, as scientific communication through publication is one of the most central social processes in science. Moreover, one form of scientific publication, the peer-reviewed article, has become the single most important aspect according to which academics in South Africa and abroad are rewarded. The focus on gender differences is motivated by the fact that women have been strengthening their representation in South African HEIs, but not their proportional contribution to our country's output of accredited research articles.A review of the past four decades of empirical and theoretical work on the gender gap in publication productivity leads the author to identify three sets of factors that may account for its existence: gender-socialised differences between women and men, women's greater family responsibilities, and gender-related deficits in the academic workplace. However, none of these sets of variables by themselves satisfactorily account for gender differences in publication productivity, and they should not be considered independent from each other. The literature review is followed by a review of methodological considerations that need to be taken into account when studying gender differences in publication productivity. Against this background, the advantages and limitations associated with the first empirical project of the dissertation - a secondary analysis of SA Knowledgebase, an existing bibliometric database - are identified.This analysis is aimed at quantifying gender differences in the publication productivity of South African academic authors; at controlling for relevant variables (race, age, highest qualification, rank, institutional affiliation and scientific domain); and at investigating gender differences in the tendency towards joint authorship. The results show that South African male authors publish almost twice as many articles in accredited journals than women authors do, but that the latter's contribution to the total scientific publication output of South Africa has increased from 16 percent in 1990 to 24 percent in 2001. Part of the gender gap in publication productivity can be explained by women's younger age, lower qualification level and lower rank as a gender group, but not by any tendency among women to co-author less than men do.This project was complemented by the analysis of primary data collected from the CVs of and qualitative interviews with sixteen highly productive South African academics. This second project contributes to the development of a more in-depth understanding of the way in which men and women's publication productivity is differentially affected, in a predominantly male milieu and across the span of their careers, by their family responsibilities, non-research academic roles, and gender-socialisation. The dissertation concludes with an integration of the literature review with the main findings of the two projects, on the basis of which recommendations are made for future research, and proposals are made towards rendering the measurement of publication productivity more sensitive to the gender differences highlighted by the dissertation.
