Abstract
This chapter evaluates the research productivity and scientific impact of Nigerian health sciences frontline academics in the diaspora. Forty-three Nigerian health sciences professors employed in universities from different parts of the world were identified using the snowball sampling technique. Subsequently, their bibliometric scores on the Scopus® database were obtained. The professors have a median Scopus® publication count of 68.0, H-index score of 18, citation count of 1286.5, co-authorship count of 134.5, m-Quotient score of 0.841, and 27.0 years of research experience. Overall, the median numbers of publications, citations, co-authors, H-index, and m-Quotient scores, including years of research experience, are not significantly different (p > 0.05) between men and women and between the two health specialties—medicine/dentistry and the “other” disciplines. However, the median publication count for the US professors (95.0) is significantly higher (χ2 = 7.516, p < 0.05) than for those in the United Kingdom (64.50) and the “other” countries (50.0). Similarly, the median H-index score for the US professors (22.0) is significantly higher (χ2 = 7.799, p < 0.05) than for those in the United Kingdom (16.50) and the “other” countries (15.0). Furthermore, the median citation count for the US professors (2726.0) is significantly higher (χ2 = 6.180, p < 0.05) than for those in the United Kingdom (913.0) and the “other” countries (887.0). Finally, the median m-Quotient score for the US professors (0.909) is significantly higher (χ2 = 8.439, p < 0.05) than for those in the United Kingdom (0.714) and the “other” countries (0.350). Olufunmilayo Olapade, Samuel Achilefu, Kunle Odunsi, and Bankole Johnson are the most prolific and impactful Nigerian health sciences academics in the diaspora.KeywordsNigeriaDiasporaMigrationHealth sciencesMedicine/dentistryBasic medical sciences/allied health/pharmacyProfessorsResearch output/impactScopus®Bibliometric parametersPublicationsCitationsCo-authorsH-indexm-Quotient
