Nicaragua is a small country in Central America and little has been published about its scientific output. Most of its publications available in international databases are about medicine and are produced by Universidad Nacional Autónoma de Nicaragua (Managua) as part of international collaborative teams. In this article we analyzed in more depth, and for a longer period than any previous study, the presence of Nicaraguan publications in the Science Citation Index Expanded until January, 2016. In total, 837 Nicaraguan articles were published in 456 journals (the top journal is the American Journal of Tropical Medicine and Hygiene). Internationally collaborative articles with 94 countries accounted for 92 % of articles, while only 8.5 % were exclusively Nicaraguan. The most cited article described the use of ketoconazole to treat Leishmaniasis. The authors with more publications in the database were A. Balmaseda, R. Peña, W. Strauch, and F. Bucardo. The top cited, exclusively Nicaraguan articles dealt with health problems, forest tenure, and food production. The article citation lifespan is surprisingly long: over 70 years. Most citations start seven years after publication and are not recorded by the Science Citation Index, which for that reason cannot be considered valid to evaluate the impact of Nicaraguan research. The predominance of English publications may reflect a bias of the database itself. Probably most of the scientific production of Nicaraguan scientists is published in Spanish, in many regional journals not included in the SCI-EXPANDED. Nicaraguan research centers lack appropriate infrastructure, staffing and financial resources: future achievements for Nicaraguan science should include a fair presence of female researchers, peer-to-peer level participation in international teams, and less dominance of health technologies.

Cameroon is one of the six countries of Central Africa with more than 20 000 000 residents. To characterize the Cameroon research performance, Cameroonians publications in the Science Citation Index Expanded during the period of 1936-2015, indexed in the Thomson Reuters SCI-EXPANDED database, were studied in this work. All documents of that period with Cameroon in the address field were included in the study. The document type, language, trend and collaborations were analyzed, as well as the output of different subject categories. Performances of countries, institutions and authors, including total, single, collaborative, first author, and corresponding author publications were also analyzed. Articles were analyzed by the scientific output and research performances of individuals, institutions and collaborative countries with Cameroon. Analyses included 8 457 articles (85 % of 10 591 Cameroonian publications). These bibliometric analyses of Cameroonian publications provided interesting insights concerning authors, institutions and collaboration patterns. Results showed that research in Cameroon was highly dependent on foreign collaborations, and the international collaboration was responsible for the increasing number of publications over the years. It was found that the articles with either first authors or corresponding authors from outside Cameroon got more citations than the others, and that the articles without any international collaboration had lower citations. The number of articles indexed by SCI-EXPANDED has seen an increase in terms of Cameroonian articles that is considerably greater that the increase in number of all articles in SCI-EXPANDED. Articles were more frequent than other types of publication and they were mostly in English. The University of Yaoundé I ranked top one in inter-institutionally collaborative articles, the rank of the total inter-institutionally collaborative articles, and the rank of first author articles and corresponding author articles. The University of Yaoundé I also was in an absolute leading position from 1970s to 2015, followed far away by the other institutions. The categories of tropical medicine, plant sciences, environmental and occupational public health, and infectious diseases, represented the largest number of published articles. Even though physics and chemistry dominated the ranking of the top 20 best Cameroonian authors, an independent mathematics article was the most cited, with 60 citations in 2015 to a Cameroonian author. The top three productive researchers were T. C. Kofane, B. T. Ngadjui, P. Woafo, all from University of Yaoundé I. France and the USA dominated the ranking of countries with strong scientific collaboration with Cameroon.

Introduction: In Benin, a tropical West African country of 11 million inhabitants where the economy is based on agriculture, the only bibliometric work available has focused on the role of collaboration among researchers, but there are no general long term studies of the country’s scientific output. Objective: To analyse the scientific output of Benin, according to the Science Citation Index Expanded, in a 46-year period. Methods: We searched for “Benin” in the country/region field of the index and analysed the results with descriptive statistics. Results: We found 4 557 documents, published between 1973 and 2018. They closely match the trends previously found in other small tropical countries: domination of articles over other types of publication like letters and notes; increase in total number of articles published each year; small collaborations in large American and European projects; and a long article lifespan that reflects the relatively slow accumulation of scientific research in tropical regions. Considering the size of the country’s economy, Benin has a good level of scientific productivity. Conclusion: In its scientific activity, Benin is similar to other tropical countries, and would benefit from increased cooperation among local researchers; from less dependence on small participations in international megaprojects, and from opening the door to research in areas of innovation rather than just solving immediate problems.

PurposeThe purpose of this paper is to examine the quantum of research papers and the citations these papers received for the plantJatropha curcas Linn.Design/methodology/approachArticles published onJatropha curcas Linnduring 1987–2016 were downloaded from Science Citation Index-Expanded (SCIE) by using the keyword Jatropha* on October 18, 2017. The search resulted in 4,276 records in all. The authors analyzed only 4,111 documents which were published as review articles, research articles and proceeding papers using the complete count methodology. The data were analyzed to examine the pattern of growth of output, most prolific countries, institutions and authors. It also identified highly cited authors and journals used for communicating research results.FindingsThe study indicates that India, China and Brazil are the main contributors to the field and the pattern of growth indicates a steep rise in publication output especially in the last block of 2015–2016. Most of the prolific institutions and authors were also located in these countries. However, the impact of output was different from the pattern of output. The publication output is scattered in more than 1,000 journals published from different parts of the globe.Originality/valueThe plant ofJatropha curcas Linnis a highly useful plant as a source of biofuel energy. This is the second study in English language on this plant and has used a large set of publication data as compared to the first. The findings of the study may be useful for policy makers as well as for researchers working in the field of biofuel energy.

Ghana is a West African country for which apparently there are limited scientometric studies. The objective of this study was to analyze the Ghanaian contribution to knowledge captured in the Thomson Reuters Science Citation Index Expanded (SCI-EXPANDED) database from 1936 - 2016. The following data were analyzed: document type, the language of publication, publication trend, Web of Science Subject Categories, Journals, international collaboration, institutions, authors, and highly cited articles. Indicators such as the total number of articles, first author articles, and corresponding author articles were applied to compare publication performance for collaborative countries and institutions. Also, number of single institute articles: number of nationally collaborative articles: number of internationally collaborative articles (S : N : I) were also used to compare publication characteristics of institutions in Ghana. Results showed that publication trend increased from 1998 to 2015, with researches focusing on health and medicine. PLoS One was the top productive journal, and the most collaborative country for Ghana articles was the USA. Contributions from the University of Ghana were ranked the top one institution for Ghana articles, and higher citation papers were found in international collaborations. In conclusion, the contribution to knowledge of Ghanaian authors is massive in the areas of public, environmental and occupational health and tropical medicine but the impact factor is higher for immunology, infectious diseases, and microbiology articles. Therefore, Ghanaian authors are encouraged to publish more articles in high impact factor journals with Thomson Reuters Scientific indexing in order to have their researches recognized by the existing international databases.

This study was conceived to evaluate the global scientific output of secondary organic aerosol (SOA) research over the past 20 years and to assess the characteristics of the research patterns, tendencies, and methods in the papers. Data were based on the online version of Science Citation Index Expanded from 1992 to 2011. Publications referring to SOAs were assessed by distribution of the number of publications and times cited, source categories, source journals, author keywords, KeyWords Plus, and the most cited publications in these years. By synthetic analysis of author keywords, KeyWords Plus, titles, and abstracts, it was concluded that modeling is currently and will at least over the next decade continue to be the predominant research method to validate state-of-the-art knowledge of SOAs, and that the foci of SOA research will be the key precursors terpenes and isoprene, the mechanisms of oxidation and gas-phase reactions, and emission inventories.
