Africa’s contribution to the worldwide research literature: New analytical perspectives, trends, and performance indicators

Geography of Africa biomedical publications: An analysis of 1996–2005 PubMed papers

“…Our study shows that research production in Africa is highly skewed; South Africa accounts for one third of Africa's publication output, Egypt and Nigeria jointly account for another one third, result that is congruent with the findings of previous studies [21,31]. In this study, we found like others [1,2,21,[32][33][34], that highly populous countries have corresponding high levels of PubMed publications; and smaller countries can very productive.…”

“…In this study, we found like others [1,2,21,[32][33][34], that highly populous countries have corresponding high levels of PubMed publications; and smaller countries can very productive. Taking into consideration of their GDP, we found that the better the economic ranking of a country the higher the quantity of its biomedical publications.…”

“…There are number of useful bibliometric studies available which have focused in part with Africa or with specific African countries [10][11][12][13][14][15][16][17][18][19][20][21]. However, as noted by Tijssen [21] some lacks comprehensive cross-country comparison and their scope and coverage of the research literature is too constrained to serve as a broad cross-country analyses at African level.…”

Research Productivity-Visibility-Accessibility and Scholarly Communication in Southern African Universities

“…There has been a steady decline in Africa's share of world science as measured in papers published in ISI-indexes over the last two decades (Gaillard, Krishna & Waast, 1997;Tijssen, 2007), while the decline in sub-Saharan science has been dramatic, increasing marginally (Mouton & Waast, 2008). Recent analysis of SADC articles included in the citation databases of the ISI Web of Science, Medline and AJOL journals, in the study on The state of public science, confirms the picture painted by Tijssen (Mouton et al, 2008: 47-48).…”

Assessment of Scholarly Publications of Nigerian Health Sciences Researchers in MEDLINE/PubMed (1996-2007)

“…Tijssen (2007) asserted that peer-reviewed scholarly and professional journals are one of the very few internationally comparative sources of information on scientific outputs. Uthman and Uthman, (2007) stated that scholarly publications play an important role in scientific process by providing a key linkage between knowledge production and use.…”
