A 53-Year Bibliometric and Scientometric Analysis of Research in Culinary and Medicinal Mushrooms

The research field of culinary and medicinal mushrooms has been well developed since the first relevant publication in 1966. However, to date, there has been no bibliometric analysis published specifically for this field. This study aimed to assess the most influential publications as well as the research trends and important drivers in the field of culinary and medicinal mushrooms. Scopus was used to identify relevant publications and the 1000 most-cited publications were identified and analyzed. Bradford's law of scattering shows one-third of the papers were published in 14 core journals, with a total of 102 papers published in International Journal of Medicinal Mushrooms. There is an insignificant negative correlation (Pearson's correlation coefficient, r = -0.355) between the journal impact factor and publication count. VOSviewer was used to generate a country network. China represents Asia's research center in this field, having contributed 20% of the 1000 most-cited publications. A term map was also created to visualize the co-occurrence of key terms in the domain. Different biological activities such as antioxidant and antitumor properties of mushrooms appeared to be a recurring topic in this field. Wasser (2003) showed the highest citation count (n = 1282), which is almost double the second most-cited publication (n = 611). There is a weak positive correlation (r = +0.237) between the years since publication and total citation count. In conclusion, this bibliometric study will assist researchers to comprehend the current status of the research on culinary and medicinal mushrooms, and to visualize the future impact of such an important field.

SCIENTIFIC PRODUCTION IN ONLINE JOURNALS ABOUT THE NEW CORONAVIRUS (COVID-19): BIBLIOMETRIC RESEARCH

ABSTRACT Objective: to describe the bibliometric indicators of scientific production available in online journals that address Covid-19. Method: bibliometric study using Bradford's Law, network maps and textual statistics conducted with publications available in databases, from January to March 2020. Results: the sample consisted of 110 scientific articles. The main authors of the studies were linked to 83 institutions in 30 countries, giving priority to medical training. China was the country that published the most, providing a large number of research data. Patients infected with Covid-19 and the population in general made up the study populations and the hospital environment was the place where most of the research was performed. The journal with the highest number of publications has a high scientific influence among academic journals. The predominance of themes about Covid-19 was observed through the analysis of terms. Conclusion: bibliometric indicators indicate existing directions and gaps in the scientific production of Covid-19, which will assist in the development of future research, especially at the national level.

Scientometric profile of gravity research: A study based on web of science

The study analyzes 75342 gravity research contributions of global scientists indexed in the Web of Science from 2010-2019 for a period of 10 years. The aims of the study are to know the growth of the publications, coverage of subject areas, most prolific authors, co-authorship pattern and application of Bradford's law of scattering It was found that the growth of publication was in increasing trend during the period of study. The maximum numbers of articles are published in the year 2018 and the lowest number of articles published in the year 2010. 94.38% of publications are published in the form of articles and the rest of the publications are published in other forms of communications. The degree of collaboration is in growing order and it ranges from 0.84 to 0.90 during the period of study. Sharif Mis in the first place by publishing 233 articles in the field of gravity. 5814 articles are published in the journal i.e. Physical Review D and it has ranked in the first place. In the case of relative growth rate, the growth rate is reducing, and doubling time was increasing. The application of the Bradford law of scattering does not fit into the Bradford zones.

Exemplifying the Bradford’s Law: an analysis of recent research (2014-2019) on capital structure

The theme of capital structure is considered relevant within Corporate Finance, because it refers to decisions that influence the way firms finance, impacting the value and financial commitment of organizations. The main objective of this paper is to analyze the recent (2014-2019) world academic production on capital structure through the use of the Bradford Law. To do so, we collected the scientific articles available in the Web of Science. Data analysis was done through the description and use of the Bradford’s Law. The main findings indicated that the peak of scientific production on the subject occurred in 2017 (1,765 articles); it was identified that two authors stand out as those who participated in more articles in the theme. The application of the Bradford’s Law indicated that there is concentration of production in 5% of the journal (taken as 'core' of the publication on capital structure) which 2387 works. The journals considered 'important' correspond 19% (531 of them), publishing 2,262 articles. The other journals are considered 'noise', once they have published two or one articles. Because it is a relevant topic both in the business and academic aspects, as well as the fact that there are still gaps in the literature, new research is still expected, which makes it necessary to investigate how this research is behaving.

Application of Bradford's Law of Scattering to the Economics Literature of India and China: A Comparative Study

This paper deals with the applicability of Bradford law of scattering of the publications of India and China. The data for the study collected from WOS database, 887 journals publishing 1924 economics subject publications from India and 1627 journals published 4427 Chinese economics publications. The ranked list of journals prepared for both the datasets and the applicability of Bradford’s law was tested. The journals distribution pattern of the economics literature fit Bradford’s distribution pattern. The applicability of Egghe’s model (modification of Leimkuhler’s model) was also tested and found valid for both the datasets.

Worldwide tendency and focused research in forensic anthropology: A bibliometric analysis of decade (2008-2017).

The objective of this study was to illustrate the global research productivity and tendency of forensic anthropology in recent ten years (2008-2017) by bibliometric analysis. "Forensic anthropology" was used as the Medical Subject Headings term and topic in PubMed and Web of Science Core Collection. As 5130 articles retrieved, two independent investigators evaluated all of them respectively. After restricting the published year, excluding duplicated and irrelevant articles, 1663 articles were available. The total of 219 countries and regions contributed to this research and the United States was the most productive country. There were 201 peer-reviewed journals including all of articles and two of them were identified as core journals according to Bradford's law. Eight of the top 10 productive authors were from developed countries. The top 10 cited articles were published by authors from developed countries with half in the United States. Sex estimation and age estimation were the most popular topics. With the basic and recognized methodology administered in this study, it provided a relative broad view to evaluate the scientific research capacity of forensic anthropology and reveal the worldwide tendency in this field.

Worldwide scientific production in obstetrics: a bibliometric analysis

Randomised clinical trials are considered to be the most reliable study design for assessing the efficacy and safety of health interventions. To analyse worldwide obstetrics research carried out through randomised clinical trials, from 2002 to 2013. A bibliometric analysis was performed. Publications on obstetrics that were published journals indexed in the MEDLINE database from 2002 to 2013 were analysed. The major medical subject headings used in the search were obstetrics, pregnancy complications and obstetrics surgical procedures. The main study outcome was index of research productivity. Our study search strategy yielded a total of 142,659 articles and 9967 clinical trials. The growth rate of scientific production in obstetrics during this period was 55.43% (n = 5094). The growth rate of production of randomised clinical trials in this specialty, meanwhile, was 97.84% (n = 544). Most of the identified authors (n = 22,622, 71.21%) published only one paper during the study period. Patterns of co-authorship among the 20 most productive authors were identified. After applying Bradford's law, six journals in the nucleus (the most prolific journals) were found. Of all the clinical trials in obstetrics published between 2002 and 2013, 10.3% were published in journals belonging to categories other than Obstetrics and Gynecology. The most common research topic in 2002 and 2013 was the use of analgesia and anesthesia in obstetrics. Total scientific production rate in obstetrics increased from 2002 to 2013, especially randomised clinical trials. However, randomised clinical trials continue to represent a small proportion of total production.

Research Contribution of Bibliometric Studies as Reflected in Web of Science from 2013 to 2017

An attempt has been made in this paper to identify the research productivity on the bibliometrics subject published from 2013 to 2017 in the Web of Science database. 1422 research articles on bibliometrics published in various library science journals and indexed in the web of science database are considered as a basis of data for the study. In this article, we made an attempt to analyze the pattern of publication of 1422 research articles. The study involved on various bibliometric components such as annual growth rate, authorship pattern, distribution of contribution by country wise, language-wise, institution wise, most prolific author in the field, high productivity of Journals, etc is studied. On an average 284 articles were published in each year during the study period and the highest number of articles are recorded in the year 2016. Further, the USA is contributed to the highest number of research articles (22.2%). The journal “scientometric” ranks as the first core journals in the subject of library science by contributing 37% of the total publications. Finally, the study concluded that there has been consistent growth of literature in the field of bibliometric studies and also given data set well fitted with the Bradford law of scattering of literature.

Scientific production on workplace bullying and nursing: a bibliometric study.

To verify bibliometric indicators of the scientific production available in online journals that approach workplace bullying and nursing. A bibliometric study making use of Bradford's law, Zipf's law, and textual statistics was carried out with publications in Portuguese, English, and Spanish, made available in national and international databases, from 2000 to 2016. The sample was made up of 111 publications. The main authors had connections with 91 institutions distributed in 24 countries. The United States, Brazil, and Australia were the countries with the most publications. The populations of the studies were made up of nursing professionals and students, and the hospital environment was the most studied setting. The journals with a higher number of publications have international scientific influence. The terms that presented greater semantic power and high frequency in the abstracts were: bullying; assédio moral; and acoso laboral. Indicators showed that workplace bullying occurs in the nursing work environments of several countries, and the number of publications on this theme has tended to increase. Diversifying methods and study settings is important to contribute to the advancement of knowledge and fight against this violence.

Trends and topics in occupational diseases over the last 60 years from PubMed.

Objectives The purpose of this study was to provide an analysis of scientific production on occupational diseases (OD) during the period 1945-2015 in order to describe publication trends on that topic and identify the major diseases as well as the predominant actors (journals, countries) involved in this field. Methods A PubMed search was carried out to extract articles related to occupational diseases during the period 1 January 1945 to 31 December 2015 using a specific query. Data were downloaded from PubMed in Extensible Markup Language (XML) and processed through a dedicated parser. Results A total of 160 025 articles were retrieved from 7127 journals. One third of these articles were published in 39 journals: the core journals according to Bradford's law. Following exponential growth, OD publications reached a plateau in 2007. The overall dynamics of the OD field are heterogeneous with differences between subfields: psychological diseases emerged in the 1990s while "traditional" OD are less studied nowadays. Despite a sharp decrease in the proportion of publications, the most productive country remains the USA with 14.5% of the OD publications over the period but Scandinavian countries are, proportionally, the most active in research and publication on OD. Conclusions The proportion of publications on OD is decreasing in Medline, except for specific subfields of OD. This is discrepant with the global burden of occupational diseases.

Doctoral Theses in Environmental Science

The result of this study is an original research work with application of Bradford's law and an obsolescence study of environmental science literature. The article represents the availability of information and information used by the researchers in the field of environmental science for their research work. The research design adopted was a descriptive study. Data was collected from 66 doctoral theses submitted to the Kuvempu University in the field of Environmental Science during 1998-2012 have been taken as the source of data for the present study; these doctoral theses generated 14,668 total citations. The study is based on the analysis of bibliographic references appended at the end of each chapter and footnotes, if any. Each thesis was manually examined and references appended at the end of each chapter were extracted. All the references were noted. Later, the data were fed into the computer using MS-Excel and separate sheets and columns were created to enter data. Finally, the data was transferred to SPSS software to generate the tables, graphs and results. The present article reveals that journals have the highest number of citations accounting to 72.25% of the total citations. The Journal of Hydrobiologia from the Netherlands occupies the first rank as the most preferred journal having been cited 546 (5.15%) times. Further, Bradford's law was applied and studied the obsolescence of journal literature. Finally half-life of journal citations was found 14 years old in the field of Environmental Science.

Using Bradford's law of scattering to identify the core journals of pediatric surgery

BackgroundBradford's law of scattering defines an exponentially diminishing return when extending a search for references in journals and can be used to identify the “core” journals in a field. The purpose of this study was to identify the core journals of pediatric surgery. MethodsWith Institutional Review Board approval, we developed bibliometric profiles for the top academically productive pediatric surgeons in the United States. These profiles included the total number of publications, journals in which those authors published their manuscripts, and identification of all articles cited by those surgeons, along with the journals those references were drawn from. Bradford's law of scattering was applied to identify the core journals of pediatric surgery. ResultsWe identified n = 69 pediatric surgeons (10 ± 0.2 5-year h-index). These authors published 10,031 articles (145 ± 90 per surgeon), which were cited 250841 times (3635 ± 413 per surgeon). Pediatric surgeons' articles contained 199507 references (2891 ± 176 per surgeon). We analyzed 58,310 references (top 20 journals) cited by pediatric surgeons. Bradford's Law identified a single core journal for p = 3-10 zones, with P = 3, providing the best correlation between predicted and actual values (Rˆ2 = 0.9996). The core journal for pediatric surgery is Journal of Pediatric Surgery. ConclusionsWe used Bradford's Law to identify the core journals of pediatric surgery. These core journals include the two leading pediatric surgery–specific journals and the highest impact factor journals in surgery (Annals of Surgery) and medicine (NEJM). These findings can help busy pediatric surgeons focus their reading to stay updated in a rapidly evolving field.

Stress in nurses: The 100 top-cited papers published in nursing journals.

To identify and analyse the 100 most cited papers on stress in nurses published in nursing journals. The number of citations an article receives is an index of its impact on the scientific community. An analysis of the most cited articles on stress in nursing would allow us to identify the most important articles and to obtain information about this area of knowledge. A retrospective bibliometric analysis. In 2016, 111 journals belonging to the "nursing" category were identified in the Science and Social Science Citation Index. A search was performed of the Science Core Collection Website for articles on stress published in these journals. The topic, type of article, publishing journal, countries and institutions of origin and year of publication were extracted from the articles. The impact factor, immediacy index, journal country and publisher and h index were collected from the Institute for Scientific Information. The citation density, citation tendency and Bradford's law were calculated. They identified articles were mostly empirical quantitative studies with a transversal design, published from 1975 - 2011 in 23 journals. They were signed by 233 authors, most of whom are English-speaking from the USA and UK. The core distribution of the publications comprises a single journal, the Journal of Advanced Nursing. The study of stress in nursing has shown increased visibility and recognition each decade. The most recent articles have the highest number of citations, are the highest in rank and have the higher citation densities.

The core journals were: Zhongguo Zhen Jiu [Chinese Acupuncture & Moxibustion], Evidence Based Complementary and Alternative Medicine, and Zhen ci yan jiu [Acupuncture research]. Almost all (98.80%) of publications were present in the SCImago Journal Rank, where 50% of the production is presented in the first quartile. The language coverage of publications focuses on two languages, English (69.23%) and Chinese (30.77%). ConclusionsA comprehensive strategy needs to be implemented in order to continue advancing in this field, with a greater involvement of researchers both at national and international level.

O que Bardin diz que os autores não mostram? Estudo das produções científicas brasileiras do período de 1997 a 2015

Este estudo apresenta a análise de artigos publicados em periódicos brasileiros, no período de 1997 a 2015, que utilizaram o método de análise de conteúdo da autora Laurence Bardin. A metodologia é exploratória, com perspectiva temporal longitudinal, tendo como forma de pesquisa a documental, abordagem quantitativa e qualitativa. Foram analisados 52 trabalhos publicados em língua portuguesa, disponíveis no portal de periódicos Scientific Periodicals Electronic Library (SPELL) e Scientific Electronic Library Online (SCIELO). Para organização e tabulação, foram utilizados os softwares Atlas.ti e Microsoft Office Excel, analisados pelo método da bibliometria, quantificando, descrevendo e prognosticando o processo de comunicação escrita de acordo com a Lei de Bradford, Lei de Lotka e Leis de Zipf (GUEDES, 2012). Além disso, os trabalhos foram explorados qualitativamente de acordo com a aplicação do método e classificados como parciais, mínimos ou totais. Os resultados demonstraram que houve uma melhora nos artigos publicados nos últimos anos, sob a ótica da aplicação e descrição, considerando as três fases: pré-análise, exploração do material e tratamento dos resultados. Alguns estudos utilizam a análise de conteúdo desprezando etapas principais, outros, apenas, citam o método na metodologia, mas não a aplicam na prática. As análises indicaram que 75% (39 de 52) dos artigos não deixam claras as etapas definidas por Bardin, além disso, 46% (24) dos trabalhos utilizaram um método analítico auxiliar em conjunto com a análise de conteúdo.
