Impact factors, scientometrics and the history of citation-based research

[Bibliometric characterization of Revista Alergia Mexico]

OBJECTIVE

To characterize the scientific production of the Revista Alergia Mexico.

METHODS

A descriptive study was carried out that took into consideration the bibliometric information of the Revista Alergia México hosted in PubMed (MEDLINE) and Scopus.

RESULTS

The total number of articles published during 1991 to 2021 according to Pubmed was 1,115 (annual mean: 37.2 ± 12.3). Scopus registered 1,541 articles during 1972 to 2021 (annual mean: 30.8 ± 14.9); in both sources, original articles (49 and 78%, respectively) and review articles (21 and 12%, respectively) were the most published document modalities; the most relevant topics included asthma (32%), allergic rhinitis (16%) and drug allergy (9%). Public institutions in Mexico were the institutions with the highest number of published articles. The country with the highest number of published papers was Mexico (54%), followed by Colombia (5%) and Spain (4%). The 2020 citation index according to Scopus was 0.9; an H-index of 15; and an impact factor of 0.150. During the period 2016 - 2020, the annual rejection rate ranged from 7% to 30%.

CONCLUSIONS

Promoting the internationalization of the journal, publishing articles in the English language and achieving the impact factor are among some of the main needs of the Revista Alergia Mexico.

Gender bias in special issues: evidence from a bibliometric analysis

Even though the majority of psychologists are women, they are outnumbered by men in senior academic ranks. One reason for this representation bias in academia is that men favor other men in decision-making, especially when the stakes are high. We tested the possibility of such bias in a bibliometric analysis, in which we coded editors' and authors' gender in regular and special issues, the latter considered of higher scientific prominence. We examined all special issues from five prominent scientific outlets in the fields of personality and social psychology published in the twenty-first century. Altogether, we analyzed 1911 articles nested in 93 sets comprising a special issue and a neighboring regular issue treated as a control condition. For articles published in special (but not regular) issues, when there were more men editors, more men first-authored and co-authored the work. This pattern suggests how gender bias can be perpetuated within academia and calls for revising the editorial policies of leading psychology journals.

Differences in Citation Patterns across Areas, Article Types and Age Groups of Researchers

The evaluation of research proposals and academic careers is subject to indicators of scientific productivity. Citations are critical signs of impact for researchers, and many indicators are based on these data. The literature shows that there are differences in citation patterns between areas. The scope and depth that these differences may have to motivate the extension of these studies considering types of articles and age groups of researchers. In this work, we conducted an exploratory study to elucidate what evidence there is about the existence of these differences in citation patterns. To perform this study, we collected historical data from Scopus. Analyzing these data, we evaluate if there are measurable differences in citation patterns. This study shows that there are evident differences in citation patterns between areas, types of publications, and age groups of researchers that may be relevant when carrying out researchers’ academic evaluation.

The Effect of Article Characteristics on Citation Number in a Diachronic Dataset of the Biomedical Literature on Chronic Inflammation: An Analysis by Ensemble Machines

Citations are core metrics to gauge the relevance of scientific literature. Identifying features that can predict a high citation count is therefore of primary importance. For the present study, we generated a dataset of 121,640 publications on chronic inflammation from the Scopus database, containing data such as titles, authors, journal, publication date, type of document, type of access and citation count, ranging from 1951 to 2021. Hence we further computed title length, author count, title sentiment score, number of colons, semicolons and question marks in the title and we used these data as predictors in Gradient boosting, Bagging and Random Forest regressors and classifiers. Based on these data, we were able to train these machines, and Gradient Boosting achieved an F1 score of 0.552 on classification. These models agreed that document type, access type and number of authors were the best predicting factors, followed by title length.

Research trends on monsoon research from 1900 to 2018 according to scientometrics analysis

To understand the history and research status of monsoon scholarly publication, a scientometrics study based on the Science Citation Index-Expanded has been made from 1900 to 2018. HistCite was used to analyze the annual outputs, countries, institutions, categories, journals, citations, and high-impact authors in the field. Results revealed that the annual number of outputs showed an increasing trend over the past decades, with an especially rapid increase after 1990. The country with the greatest academic impact was the USA, while the institution with the highest research outputs and citations was the Chinese Academy of Sciences. Meteorology Atmospheric Sciences and Geology were the most dominant categories. Journal of Climate was the most active journal, of which both in outputs and citations. Through citation visualization analysis, monsoon research mainly focuses on two aspects: modern monsoon and paleomonsoon.

Climate change and sustainable development: the case of Amazonia and policy implications

The relationship between sustainable development and climate change has been extensively addressed, but with few studies focusing on the Amazonian Rainforest. Due to its dimension and importance, preserving it is critical in order to mitigate the problem of climate change associated with rising temperatures, lower precipitation, and the increase of extreme weather events. This paper studies the effects of climate change on the sustainable development of Amazonia. A scientometric analysis was carried out which reveals the evolution of the research field in terms of the growing number of works that have been published in top journals and the main drivers of climate change in Amazonia, such as deforestation, global warming, and land use. Our results indicate that the environmental dimension of sustainable development has been the issue most studied. Our analysis leads us to recommend that policymakers implement incentives for better forest management, design policies with realistic expectations, and rely more on technical reports and approaches to implement policies. Better integration of policies at local, regional, national, and international levels is necessary in order to adapt to and mitigate climate change. Several measures to intensify the scientific approaches joining economic and social dimensions are also proposed. This work contributes to the systematization of the literature on sustainable development and climate change in Amazonia, which has not yet been done, and provides policy recommendations to researchers and professionals for a better understanding of climate change and sustainable development in the Amazonia region of Brazil.

Estimates of global research productivity in using nicotine replacement therapy for tobacco cessation: a bibliometric study

BACKGROUND

Tobacco use is a major healthcare problem worldwide. Tobacco smoking remains the most important risk factor for both cancer and heart diseases. This study was initiated due to the lack of published data concerning the real progress in research output in the use of nicotine replacement therapy (NRT) for tobacco cessation. This study was aimed to use bibliometric analysis to estimate the NRT literature indexed in Scopus database at global level.

METHODS

Core of the search strategy was the documents that contained specific words or phrases regarding NRT as keywords in the title. Publication output of most prolific countries was adjusted to the gross domestic product and population size. All citations analysis were accomplished on December 22, 2017.

RESULTS

A total of 2138 references were retrieved and published from 56 countries, which were published between 1970 and 2016. The USA has the most number of published articles accounted to 986, followed by the UK (312 publications) and then Australia (102 publications), and Sweden (102 publications). No data related to NRT were published from 156 countries. No significant correlation was found between the country population size or 2016 gross domestic product values and the number of publications of the top-10 most prolific countries in the field of NRT (r = - 0.156, P = 0.664; and r = - 0.173, P = 0.632, respectively). Furthermore, there is no correlation between prevalence of tobacco smoking and number of publications of the top-10 most prolific countries in the field of NRT (r = - 0.235, P = 0.514).

CONCLUSIONS

The present data reveal a solid mass of research activity on NRT. The USA was by far the predominant country in the amount of NRT-based research activity. NRT-based research activities were low or not available in most countries. The results of this study delineate a framework for better understanding the situations of current NRT research and prospective directions of the research in this field which could be applied for managing and prioritizing future research efforts in NRT research.

Global Trends in Aspirin Resistance-Related Research from 1990 to 2015: A Bibliometric Analysis

Aspirin resistance can be defined as the inability of the usual dose of aspirin medication to produce its antithrombotic effect. Patients with diabetes or cardiovascular disease are at higher risk of stroke, myocardial infarction or cardiovascular death due to aspirin resistance. The aim of this bibliometric study was to identify and analyse the status and trends of aspirin resistance research production at global level through publications indexed in the Scopus database; this will shed new light on future research trends and help researchers predict dynamic direction of research. Literature search using the Scopus database was conducted to assess publications related to aspirin resistance. The selected publications included the terms related to aspirin resistance in the title, abstract or keywords. The searching was accomplished on 20 March 2016 and can be considered to include all publications up to 31 December 2015. Global cumulative publication output on aspirin resistance consists of 986 papers during 1990-2015. Among the 986 documents, 19 (1.9%) were published before 2000, 567 (57.5%) were published from 2000 to 2009 and 400 (40.6%) were published from 2010 to 2015, with peak of publications on this topic in 2008. The leading country in the field of aspirin resistance was the United States, which had the greatest counts of independent articles (165) and international collaboration articles (44). Turkey was in the second rank with 78 articles, followed by Italy (68), the UK (62) and Poland (60). The total number of citations for all documents was 26,342, and the average citations per document were 26.7. The h-index for all aspirin resistance publications was 82. This study presents the results of the first bibliometric study (including quantitative and qualitative analysis) of scientific publications in the field of aspirin renitence at global level. Aspirin resistance-related researches have notably increased in the last years, especially from 2000 to 2015. The United States is the most prolific country, not only in research quantity but also in quality. Furthermore, Turkey and European countries provided more research related to aspirin resistance than other regions such as the developing countries.

Bibliometric analysis of rheumatology research in the Arab countries

Background

The Arab world has seen an increase in the burden of musculoskeletal diseases. No bibliometric studies have characterized rheumatology research in the Arab world. This study evaluates the productivity and impact of rheumatology research in the Arab world.

Methods

We searched the Web of Science Core Collection for rheumatology publications, from 1976 to 2014, for each of the Arab League (AL) countries, North America, Europe and Asia. For the AL countries, the overall trend of publications and citations was analyzed, while considering the paper type and collaborations.

Results

The AL countries published 944 rheumatology papers over the period studied. The number of publications increased by a factor of 2.77 (95 % CI, 2.75–2.78) each decade, and citations increased by a factor of 2.36 (95 % CI, 0.96–5.82). The absolute number of papers included in the top-10 rheumatology journals remained constant but the proportion decreased. Papers involving collaboration among AL countries were found to increase over time.

Conclusions

Overall, the AL countries lag in research productivity and impact compared to other regions. Three countries are responsible for the majority of publications, while four countries receive the majority of citations.

Global methaemoglobinaemia research output (1940-2013): a bibliometric analysis

Bibliometric studies, which involve the use of statistical methods, are increasingly being used for research assessment. A bibliometric analysis was conducted to evaluate the publication pattern of methaemoglobinaemia research output at the global level based on the Scopus database. We analysed selected documents with "methemoglobinemia", or "methaemoglobinaemia" as a part of the title and reported the following parameters: trends of publication output, country of publication, journal pattern, collaborative measures, citations pattern, and institute productivity. A total of 1770 articles were published worldwide. The time trend for the number of articles showed an increase after 2000. The highest number of articles related to methaemoglobinaemia was from the USA (24.8 %), followed distantly by the UK (4.5 %), India (3.7 %), and France (3.7 %). No data related to methaemoglobinaemia were published from 152 countries. The total number of citations at the date of data collection was 10,080, with an average of 5.7 citations per document. The USA and UK had the highest h-index of 31 and 14, respectively, and six countries had an h-index of 9-14. It is notable that Canada was ranked eighth in the number of publications but fourth in h-index and India was ranked third in the number of publications but eighth in h-index. Furthermore, Canada produced the most internationally collaborated papers out of the total number of publications for each country (16.1 %), followed by the UK (13.9 %). This bibliometric analysis provides data contributing to a better understanding of the methaemoglobinaemia research field. The number of publications on methaemoglobinaemia increased significantly after 2000. The USA was the most productive country as measured by total publications. The USA and UK achieved the highest h-index in the field of methaemoglobinaemia research, signifying a higher quality of research than other countries.

Global research productivity of N-acetylcysteine use in paracetamol overdose: A bibliometric analysis (1976-2012)

PURPOSE

The main objective of this study was to examine the publication pattern of N-acetylcysteine (NAC) research output for paracetamol overdose at the global level.

METHODS

Data were searched for documents that contained specific words regarding NAC and paracetamol as keywords in the title and/or abstract and/or keywords. Scientific output was evaluated based on a methodology developed and used in other bibliometric studies. Research productivity was adjusted to the national population and nominal gross domestic product per capita.

RESULTS

The criteria were met by 367 publications from 33 countries. The highest number of articles associated with the use of NAC in paracetamol overdose was from the United States of America (USA; 39.78%), followed by the United Kingdom (UK; 11.99%). After adjusting for economy and population power, USA (2.822), Iran (1.784) and UK (1.125) had the highest research productivity. The total number of citations at the time of data analysis (14 March 2014) was 8785 with an average of 23.9 citations per document and a median (interquartile range) of 6 (1-22). The h-index of the retrieved documents was 48. The highest h-index was 32 for USA, followed by 20 for UK. Furthermore, the highest number of collaborations with international authors for each country was held by USA with 11 countries, followed by Canada with 7 countries.

CONCLUSION

The amount of NAC-based research activity was low in some countries, and more effort is needed to bridge this gap and to promote better evaluation of NAC use worldwide. Our findings demonstrate that NAC use for paracetamol overdose remains a hot issue in scientific research and may have a larger audience compared with other toxicological aspects. Editors and authors in the field of toxicology might usefully promote the submission of work on NAC in future to improve their journal's impact.

Bibliometric analysis on global Catha edulis (khat) research production during the period of 1952-2014

BACKGROUND

Publication of scientific articles related to khat (Catha edulis) in peer-reviewed journals is considered a measure of research productivity. The principal objectives of this study were to quantify the research contribution related to khat at the global level, as well as to determine its relative growth rate, collaborative measures taken, productivity at the institutional level, and the most prolific journals publishing on the topic.

METHODS

On the basis of title words related to khat, publications were identified for all data in Scopus bibliographic database's history up to December 31, 2014. The research productivity for the top 10 countries was evaluated in relation to the population size and gross domestic product (GDP) in 2013.

RESULTS

The criteria were met by 651documents published in 51 countries. The largest number of articles associated with khat was from the UK (15.2 %), followed by Yemen (10.3 %), the USA (9.7 %) and Ethiopia (9.1 %). Ethiopia, Yemen, and Kenya had the highest productivity of publications after standardization by population size and GDP. Furthermore, Yemen achieved the highest number of collaborations, by having researchers from 19 countries. Ethiopia followed, having researchers from 16 countries.

CONCLUSIONS

This bibliometric study provides a demonstration for the worldwide research activity regarding khat. The number of articles related to khat has increased rapidly over the last 10 years. The present study is a good starting point to evaluate research activity in the field of khat. Although the data shows a promising increase in the research activity, the quantity of khat-related research is still too little compared to the massive use of khat in certain countries.

Citation classics published in knowledge management journals. Part I: articles and their characteristics

Purpose

– The purpose of this study is to develop a list of citation classics published in knowledge management (KM) journals and to analyze the key attributes and characteristics of the selected articles to understand the development of the KM discipline.

Design/methodology/approach

– This study identifies 100 citation classics from seven KM-centric journals based on their citation impact reported by Google Scholar and analyzes their attributes.

Findings

– The KM discipline is at the pre-science stage because of the influence of normative studies espousing KM practice. However, KM is progressing toward normal science and academic maturity. While the discipline does not exhibit the signs of the superstar effect, scholars from the USA and UK have made the most significant impact on the development of the KM school of thought. KM scholars should be more engaged in international collaboration.

Practical implications

– Practitioners played a key role in the development of the KM discipline and thus there is an opportunity to develop more scientific research approaches based on critical and performative research agenda.

Originality/value

– The study is novel and a must read for KM scholars because it is the first to comprehensively analyze the ideas that are the origins of the KM discipline.

Bronchial asthma and chronic obstructive pulmonary disease: research activity in Arab countries

BACKGROUND

Chronic respiratory diseases, like bronchial asthma and chronic obstructive pulmonary disease (COPD), are a worldwide health problem. Quantitative and qualitative assessment of asthma and COPD-related research from Arab countries has not been explored and there are few internationally published reports on such field. The main objectives of this study were to analyze research output originating from Arab countries in the field of bronchial asthma and COPD.

METHODS

Original scientific articles or reviews published from the 22 Arab countries were screened using specific words pertaining to asthma and COPD using Scopus database and search engine. Research productivity was evaluated based on: (a) total and trends of contribution of each Arab country to asthma and COPD research and (b) journals in which researchers from Arab countries published their research.

RESULTS

The total number of original research and review articles published globally about bronchial asthma and COPD was 163,964. The leading country in bronchial asthma and COPD research was United States of America (38,632; 23.56%). Worldwide, Turkey ranked 19th while Israel and Iran ranked 25th and 29th respectively. Among Arab countries, Egypt and Kingdom of Saudi Arabia came on positions 39th and 43rd, respectively. A total of 1,304 documents about bronchial asthma and COPD were published from Arab countries which represents 0.8% of the global research output. Research in bronchial asthma was almost double that in COPD. Research from Arab countries was low and showed a significant increase after 2000. Approximately 12% of research activity in asthma and COPD from Arab countries was published in Saudi Medical Journal, Annals of Saudi Medicine, Eastern Mediterranean Health Journal and Tunisie Medicale. Kingdom of Saudi Arabia, with a total publication of 353 (27.07%) ranked first among the Arab countries while University of Kuwait was the most productive institution with a total of 123 (9.43%) documents.

CONCLUSIONS

The present data showed relatively low research productivity about bronchial asthma and COPD in Arab countries. Research output can be improved by investing more in international and national collaborative research projects in the field of asthma and COPD.

Charakteristika der meist zitierten englischsprachigen Zeitschriftenbeiträge der Publikationsjahre 1981 bis 2010 aus der Psychologie der deutschsprachigen Länder

Präsentiert werden die Befunde einer publikationsbasierten Zitationsanalyse für 28.383 englischsprachige Zeitschriftenbeiträge, die aus der Psychologie der deutschsprachigen Länder zwischen 1981 und 2010 publiziert wurden. Verwendet wurde das Web of Science, von dem knapp 90 % dieser Publikationen abgedeckt werden. Die Häufigkeitsverteilung der Fremdzitations-Anzahl ist extrem linksschief verteilt und zeigt, dass zirka 20 % dieser Publikationen nie, 60 % zwischen 1 Mal und 22 Mal und 20 % mehr als 22 Mal von anderen Autoren zitiert werden. Das Alter der Publikation und die Zitationsanzahl sind signifikant, aber numerisch niedrig rangkorreliert. Nach dem daher vertretbaren Kriterium der Anzahl der Fremdzitationen pro Jahr seit Drucklegung des Beitrages wurden die 107 meist zitierten Beiträge (TOP-107) identifiziert, die die ersten 48 Rangplätze belegen. Deren Charakteristika werden mit Bezug auf die (Ko‐)Autorenschaften, deren Internationalität, die vertretenen psychologischen Teildisziplinen und die Studienart (z. B. empirisch versus nicht-empirisch) beschrieben. Die Beschränkungen und die Möglichkeiten von Zitationsanalysen werden diskutiert, wobei ihre rationale Integration in empirisch gestützte Peer-Review-Prozeduren favorisiert wird.

A Scopus-based examination of tobacco use publications in Middle Eastern Arab countries during the period 2003-2012

BACKGROUND

Tobacco smoking is the main health-care problem in the world. Evaluation of scientific output in the field of tobacco use has been poorly explored in Middle Eastern Arab (MEA) countries to date, and there are few internationally published reports on research activity in tobacco use. The main objectives of this study were to analyse the research output originating from 13 MEA countries on tobacco fields and to examine the authorship pattern and the citations retrieved from the Scopus database.

METHODS

Data from 1 January 2003 through 31 December 2012 were searched for documents with specific words regarding the tobacco field as 'keywords' in the title in any 1 of the 13 MEA countries. Research productivity was evaluated based on a methodology developed and used in other bibliometric studies.

RESULTS

Five hundred documents were retrieved from 320 peer-reviewed journals. The greatest amount of research activity was from Egypt (25.4%), followed by the Kingdom of Saudi Arabia (KSA) (23.2%), Lebanon (16.3%), and Jordan (14.8%). The total number of citations for the 560 documents, at the time of data analysis (27 August 2013), was 5,585, with a mean ± SD of 9.95 ± 22.64 and a median (interquartile range) of 3(1-10). The h-index of the retrieved documents was 34. This study identified 232 (41.4%) documents from 53 countries in MEA-foreign country collaborations. By region, MEA collaborated most often with countries in the Americas (29.6%), followed by countries in the same MEA region (13.4%), especially KSA and Egypt.

CONCLUSIONS

The present data reveal a promising rise and a good start for research productivity in the tobacco field in the Arab world. Research output is low in some countries, which can be improved by investing in more international and national collaborative research projects in the field of tobacco.

Osteoporosis is a neglected health priority in Arab World: a comparative bibliometric analysis

Osteoporosis is an important health problem with serious consequences. Evaluation of osteoporosis scientific output from Arab countries has not been explored and there are few internationally published reports on research activity about osteoporosis. The main objectives of this study were to analyze the research output originating from Arab countries and 3 Middle Eastern non-Arab countries, particularly Israel, Turkey and Iran in the field of osteoporosis. Original scientific articles or reviews published from the 21 Arab countries, Israel, Turkey and Iran about "osteoporosis" were screened using the ISI Web of Science database. The time frame for the result was up to year 2012. The total number of original and review research articles published globally about osteoporosis was 43,571. The leading country in osteoporosis research was United States of America (14,734; 33.82%). Worldwide, Turkey ranked 16th while Israel and Iran ranked 24th and 31st respectively. Among Arab countries, Egypt and Kingdom of Saudi Arabia came on positions 41 and 45 respectively. A total of 426 documents about "osteoporosis" were published from Arab countries which represents 0.98% of the global research output. Research about osteoporosis from Arab countries was very low until 2002 and then increased steadily. The total number of citations for osteoporosis documents from the Arab world was 5551 with an average citation of 13.03 per document and an h- index of 35. Thirty (7.04%) documents published from Arab countries about osteoporosis were published in Saudi Medical Journal. Egypt, with a total publication of 117 (27.47%) ranked first among the Arab countries in research about osteoporosis while American University in Beirut was the most productive institution with a total of 47 (11.03%) documents. Compared with other non-Arab countries in the Middle East, the research productivity from the Arab countries was lesser than that from Turkey and Israel but higher than that from Iran. The present data showed low research productivity in osteoporosis field in Arab countries. Research output can be improved by investing in more international and national collaborative research projects in the field of osteoporosis.
