Science Citation Index Expanded Database Research Articles

A bibliometric analysis of two decades of aromatherapy research

BackgroundQuantitative data are lacking on the profile of published research in aromatherapy. The objective of the study was to investigate the profile of original and review articles under the topic aromatherapy using bibliometric analysis.MethodsArticles on aromatherapy, published between 1995 and 2014, were retrieved from the Science Citation Index-Expanded database from the Web of Science. The records extracted were analyzed for citation characteristics, including the distribution of publication years, languages, countries or regions, journals, articles, and authors using HistCite 12.03.17. VOSviewer v.1.61 was used to construct bibliometric diagrams.ResultsA total of 549 original and review articles, published in 287 different peer-reviewed journals by 1888 authors, were identified. There was a steady increase in the number of published articles from 1995 to 2014. The majority of the articles was written in English (95.8%) and the United States was the leading country in the total number of published articles (n = 107, 19.5%) Journal of Alternative and Complementary Medicine published the greatest number of articles on the topic (n = 31, 5.6%). The article that received the greatest number of citations was published in Complementary Therapies in Medicine. Visualization analysis based on co-occurrences of words in the title and abstract revealed three clusters of research topics, including essential oil, intervention, and complementary medicine.ConclusionsThis study provided a systematic overview of productivity and visibility of research work in aromatherapy and the findings could be used for organizing and prioritizing future research efforts in aromatherapy research.

Bibliometric spectroscopy of Russia’s nanotechnology: 2000–2014

The article investigates the scientific performance of Russia in the field of nanotechnology, focusing on production, impact and collaboration. An underlying multidisciplinary corpus of publications was extracted from the Science Citation Index Expanded database through relevant keywords. The various bibliometric findings are presented in a top-down sequence, starting with a comparative analysis of Russia and other selected countries, scrutinizing further a revitalization of science in universities and finally presenting some (possible) centers of excellence within the domestic scientific system. Focusing on the most highly-cited nano papers, I use the analysis not only in terms of percentages of world shares of publications, but also in terms of the proportions of top-1 and top-10% publications. It is shown that among the comparative countries, Russia maximally increases the citation impact depending on its internationalization efforts and that, for example, the co-authorship between Russia and Australia in the top-10% layer as well as between Russia and the UK in the top-1% layer is above expectation. Implementing the president’s initiative “Strategy of Nanoindustry Development” and the role of governmental university-centered policy are discussed in light of the performed bibliometric study.

Urban heat island research from 1991 to 2015: a bibliometric analysis

A bibliometric analysis based on the Science Citation Index-Expanded (SCI-Expanded) database from the Web of Science was performed to review urban heat island (UHI) research from 1991 to 2015 and statistically assess its developments, trends, and directions. In total, 1822 papers published in 352 journals over the past 25 years were analyzed for scientific output; citations; subject categories; major journals; outstanding keywords; and leading countries, institutions, authors, and research collaborations. The number of UHI-related publications has continuously increased since 1991. Meteorology atmospheric sciences, environmental sciences, and construction building technology were the three most frequent subject categories. Building and Environment, International Journal of Climatology, and Theoretical and Applied Climatology were the three most popular publishing journals. The USA and China were the two leading countries in UHI research, contributing 49.56% of the total articles. Chinese Academy of Science, Arizona State University, and China Meteorological Administration published the most UHI articles. Weng QH and Santamouris M were the two most prolific authors. Author keywords were classified into four major groups: (1) research methods and indicators, e.g., remote sensing, field measurement, and models; (2) generation factors, e.g., impervious urban surfaces, urban geometry, waste heat, vegetation, and pollutants; (3) environmental effects, e.g., urban climate, heat wave, ecology, and pollution; and (4) mitigation and adaption strategies, e.g., roof technology cooling, reflective cooling, vegetation cooling, and urban geometry cooling. A comparative analysis of popular issues revealed that UHI determination (intensity, heat source, supporting techniques) remains the central topic, whereas UHI impacts and mitigation strategies are becoming the popular issues that will receive increasing scientific attention in the future. Modeling will continue to be the leading research method, and remote sensing will be used more widely. Additionally, a combination of remote sensing and field measurements with models is expected.

Characteristics and trends in global tea research: a Science Citation Index Expanded‐based analysis

SummaryA bibliometric approach to assess trends in global tea research using literature in the Science Citation Index Expanded database from 1991 to 2014 has been conducted. Articles were analysed by scientific output and research performances of countries and institutions. The distribution of keywords in the articles’ titles, author‐supplied keywords and KeyWords Plus as well as citation and publication trends of tea‐related articles was used to evaluate the research trends. The research output devoted to tea science increased greatly after the year 2002 indicating a paradigm shift that demonstrated that researchers became increasingly keen on biochemical relevance of active compounds in tea in mitigating emergent health challenges over classical tea research.

BIBLIOMETRIC ANALYSIS OF CARBON DIRECTION IN NANOTECHNOLOGY: 2000–2015

Carbon nanostructures are the important component of nanotechnology (NT) become as the first global scientific and technological initiative of the 21st century. The article presents a bibliometric analysis of development of the carbon direction of NT in the period of 2000–2015, including an international dimension. The source of information was the Science Citation Index Expanded database. The shift of the world research center to the Asian region is shown, both in terms of volume and quality indicators; the dynamics of scientific influence of two groups of countries – conditionally «incumbents» and «newcomers» – has been studied. Due to the strong skewness of citation distributions, preference in the analysis is given to the percentile-based indicators, such as: the contribution of a country to the world top-10% (top-1%) segment of the most highly cited publications, the share of such publications in the country’s total output, the highly cited papers index, etc. Relying on them, the scientific «offensive» of the «newcomer» countries on the «incumbents» (eg, of China on the USA, of South Korea on Germany, of Iran on Russia) as well as phenomenon of Singapore as an effective producer of highly cited publications on the carbon nanostructures were presented more fully. The positions of Russia have been studied in more detail, the main domestic research participants have been determined, and on the basis of bibliometric criteria the center of scientific excellence in the field of graphene has been identified.

Coupled water-energy balance (CWEB) at the catchment scale and its responses to changes in climate and land surface conditions are important research area in the interdisciplinary field of eco-hydrology. In this study a bibliometric analysis was conduct to assess current status and future developments in the research area of CWEB. All research papers on the CWEB at the catchment scale published over the period of 1992-2015 were retrieved from the Science Citation Index Expanded (SCIE) database and analyzed by means of TDA (Thomson Data Analyzer), Ucinet and Netdraw. Results of the bibliometric analysis shown that:(1) the number of publications has increased greatly in the past 24 years. Research on the CWEB can be classified into three stages in terms of the number of papers published every year, research subjects and cooperation features, i.e. groping & low yield stage, expansion stage and active & high yield stage. (2) Core themes of the research are climate change, runoff, water balance, hydrological modelling, land use and land cover change, etc. The application of remote sensing and GIS technology has been continuously strengthened. More and more attentions have been paid to the study of hydrological effects of human activities and their temporal variability. (3) High impact publications were largely from Australia and American. There was a significant increase in publications from China in term of both quantity and quality. (4) The extent of international cooperation was expanding. In the past 10 years, Chinese Academy of Sciences, Tsinghua University and many other institutions in China have gradually strengthened the cooperation with a number of international scientific and educational institutions and have made great progresses in the research area of CWEB. 参考文献 相似文献 引证文献

Growth of Headache Research: A 1983-2014 bibliometric study.

Aim This study charts the growth of the scientific journal literature on headache for 30+ years (1983-2014). Methods Using the Web of Science, articles published in four two-year periods (1983-1984, 1993-1994, 2003-2004, 2013-2014) from journals indexed in the Science Citation Index Expanded database were retrieved and analyzed. Results From 1983-1984 to 2013-2014, the scientific literature on headache increased nearly fourfold (3.8) from 468 to 1776 articles; the number of participating countries more than doubled (26 to 67); and the two most prolific countries in each period were the USA and Italy. While several European countries (Italy, Germany, UK and Denmark) were among the top 10 in each period, the notable appearance of Turkey, China and Brazil among the top 10 in 2013-2014 indicates the growing geographic spread of publications on headache research. Meanwhile, the comet-like distribution of journals has not changed: two journals, Headache and Cephalalgia, persist throughout as the nucleus, with the tail increasing more than threefold from 141 journals in 1983-1984 to 462 in 2013-2014. Conclusion Our study follows the recent growth and spread of the scientific literature on headache research and should stimulate further bibliometric investigation in this field.

Analysis of scientific production and bibliometric impact of a group of Spanish clinical researchers

To study the behaviour of several indicators of scientific production and repercussion in a group of Spanish clinical researchers and to evaluate their possible utility for interpreting individual or collective scientific pathways. We performed a unicentric, ecological pilot study involving a group of physicians with consolidated research experience. From the Science Citation Index Expanded (SCI-Expanded) database, we obtained the number of publications of each author (indicator of production) and the number of citations, impact factor and h index (indicators of repercussion). These indicators were calculated individually for each of the years of research experience and we assessed the relationship between the experience of the researcher and the value of the indicator achieved, the relationship between these indicators themselves, and their temporal evolution, both individually and for the entire group. We analysed 35 researchers with a research experience of 28.4 (9.6) years. The h index showed the lowest coefficient of variance. The relationship between the indicators and research experience was significant, albeit modest (R2 between 0.15-0.22). The 4 indicators showed good correlations. The temporal evolution of the indicators, both individual and collective, adjusted better to a second grade polynomial than a linear function: individually, all the authors obtained R2>0.90 in all the indicators; together the best adjustment was produced with the h index (R2=0.61). Based on the indicator used, substantial variations may be produced in the researchers' ranking. A model of the temporal evolution of the indicators of production and repercussion can be described in a relatively homogeneous sample of researchers and the h index seems to demonstrate certain advantages compared to the remaining indicators. This type of analysis could become a predictive tool of performance to be achieved not only for a particular researcher, but also for a homogeneous group of resear-chers corresponding to a specific scientific niche.

The Mortality Associated With Chronic Widespread Musculoskeletal Complaints: A Systematic Review of the Literature.

Chronic widespread musculoskeletal complaints (CWMSC) are a prevalent condition with a large impact on quality of life and with a large burden on society. Studies investigating the relationship between CWMSC and mortality have yielded inconsistent results. The present study aimed to clarify this relationship through a systematic review of the existing literature, including meta-analyses, to estimate pooled results and heterogeneity. The MEDLINE, EMBASE and Science Citation Index Expanded databases were searched in February 2016. Broad search terms were used to identify as many observational studies as possible that investigated the association between CWMSC and mortality. The identified studies were evaluated according to predetermined inclusion criteria. Six studies fulfilled the inclusion criteria. In pooled unadjusted analyses of three studies evaluating CWMSC, a non-significant tendency of increased overall mortality was found [mortality risk ratio (MRR) 1.69, 95% confidence interval (CI) 0.91-3.14]. However, in pooled analyses of all six studies reporting adjusted results, the non-significant tendency for higher mortality rates in those with CWMSC was nearly eliminated (MRR 1.13, 95% CI 0.95-1.34). Heterogeneity between studies was moderate to high, particularly regarding the use of confounding factors. In this systematic review, based on a limited number of studies, pooled data gave no evidence of a higher mortality rate among individuals with CWMSC. The non-significant tendency for a higher mortality rate in unadjusted pooled analyses was nearly eliminated in the adjusted pooled analyses, considering lifestyle factors such as physical activity smoking. In population-based studies evaluating the relationship between CWMSC and mortality rates, we recommend that both unadjusted and adjusted analyses should be presented.

Applications of cardiotoxicity in breast cancer: a meta-analysis

Breast cancer is the most common type of cancer in women. Many antineoplastic agents used to treat breast cancer have potentially cardiotoxic effects and may lead to chemotherapy induced cardiomyopathy and heart failure. We conducted a meta-analysis to clarify the applications of cardiotoxicity in breast cancer. A published literature search was performed through PubMed, Cochrane Library, Medline, and Science Citation Index Expanded databases for articles published in English. Pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated using random or fixed effects models. Heterogeneity was assessed using χ2 and I2 statistics. We performed a formal meta-analysis using summary measures from these studies. In total, 9 published studies were included in the final analysis. The combined analysis revealed that there was non-significant regardless of the statistical ejection fraction (OR=0.98, 95% CI: 0.63-1.54, P=0.96) and left ventricular ejection fraction (OR=1.04; 95% CI: 0.69-1.56, P=0.85) decline method used. Additionally, the pooled OR was 0.99 (95% CI: 0.79-1.28) for the trastuzumab plus lapatinib combination, and 1.00 (95% CI: 0.88-1.13) for the trastuzumab plus pertuzumab combination. In this meta-analysis, there was evidence indicated that there was not a significant decrease on LVEF and EF in patients who received trastuzumab plus lapatinib and trastuzumab plus pertuzumab combination. Our study suggests that the combination of two anti-HER2 agents does not significantly increase the risk for adverse compared with anti-HER2 monotherapy in patients with adequate cardiac function prior to start of therapy.

Assessing the evolution of scientific publications in orthopedics journals from mainland China, Hong Kong, and Taiwan: a 12-year survey of the literature.

BackgroundIn China, the field of orthopedics has experienced significant growth over the past 12 years. However, the recent status of research on orthopedics among individuals in mainland China, Hong Kong, and Taiwan is unknown. In this study, we investigated characteristics and trends of orthopedics publications from these three regions.MethodsBetween 2003 and 2014, all articles published in 63 orthopedics journals originating from mainland China, Hong Kong, and Taiwan were identified via Science Citation Index Expanded (SCIE) database. A survey was conducted to systematically analyze the published orthopedics articles from the three regions according to the numbers of articles, study design, impact factors (IFs), citations, most prolific authors, and institutions. Additionally, we evaluated global trends in orthopedics publications, and ranked top 10 countries in terms of the total number of published articles over 12 years and the number of published articles per year.ResultsA total number of 123,317 articles were published in the 63 orthopedics journals between 2003 and 2014. The worldwide number of annually published orthopedics articles tended to increase during the study period. The total number of orthopedics publications from the three regions, especially in mainland China, increased markedly from 2003 to 2014. The annual number of orthopedics articles from mainland China increased from 6 in 2003 to 813 in 2014, Hong Kong increased from 32 in 2003 to 71 in 2014, and Taiwan increased from 68 in 2003 to 168 in 2014. For accumulated IFs and total citations of articles, mainland China ranked the first place, followed by Taiwan and Hong Kong. However, publications from Taiwan had the highest average citations per article, and publications from Hong Kong had the highest average IFs. Among the top 10 most prolific authors and institutions, 4 authors and 4 institutions were from Taiwan, 3 authors and 4 institutions were from mainland China, and 3 authors and 2 institutions were from Hong Kong.ConclusionsThe quantity of articles published in international orthopedics journals from mainland China presented a remarkable upward trend during the past 12 years. Given the relative size of the populations, it should be emphasized that mainland China still has a long way to go to achieve the academic performance of Hong Kong and Taiwan.

Surviving in the dispute: A bibliometric analysis of global GMF-related research, 1995–2014

Relying on the Science Citation Index Expanded and Social Science Citation Index databases, a bibliometric analysis of global studies on the genetically modified foods (GMF) in the last 20 years was conducted. We explored the knowledge foundations, research areas, authorships, spatiotemporal patterns, and the trendy. The GMF-related research maintains stable growth with established research teams and sufficient funds in the recent years. GMF-related research is a young field with a newly established intellectual base, and widely recognized as bio-science study. Journal of Agricultural and Food Chemistry, European Food Research and Technology, Food and Chemical Toxicology were the most active journals in the field. H. Akiyama, R. Teshima, A. Hino and A. Cifuentes were the most prolific authors in GMF-related research. For countries, both the pro-GMF and anti-GMF countries have pushed relevant research, including USA, EU, and Japan. Considering the GMF as national non-traditional security issue, inter-institute collaborations were more visible than that of international collaborations. Through keyword analysis, we found that the trendy of GMF-related research has been shifted from a pure technological perspective to a combination of technology, food safety and public acceptance.

A bibliometric analysis of micro/nano-bubble related research: current trends, present application, and future prospects

With great versatile characteristics, micro/nano-bubble related research have attracted much attention due to their extensive applications in the last half century. Researchers not merely focus on their physi-chemical properties, but also aim at their well-controlled generation methods and potential adhibition field. It can be expected that the future prospects of micro/nano-bubble related research will be tremendous and that there will be even more to be explored. In this case study, a bibliometric was conducted to evaluate micro/nano-bubble related research from 1991 to 2014, based on the Science Citation Index EXPANDED database. The Ultrasound in Medicine and Biology with the highest h-index of 56 is the leading journal in this field, publishing 6.9 % of articles over this period, followed by Langmuir and Journal of the Acoustical Society of America. USA and the Univ Toronto, Canada were the most productive country and institution, respectively, while the USA, was the most internationally collaborative and had the highest h-index (111) of all countries. A new method named word cluster analysis was successfully applied to trace the research hotspots. Innovation in detection means and novel pathways for medical applications via micro/nano-bubble is considered to relate to the increasingly new types and varieties of diseases or cancers, as well as the well-controlled generation of micro/nano-bubbles.

Research trend of metal–organic frameworks: a bibliometric analysis

A bibliometric analysis based on the related articles in the Science Citation Index Expanded database was conducted to gain insight into global trends and hot issues of metal---organic frameworks (MOFs). The word clusters of synthesis methods, MOFs' properties and potential applications and some representative MOFs with related supporting words in title, author keywords, abstract, along with KeyWords Plus were proposed to provide the clues to discover the current research emphases. Y index was introduced to assess the publication characteristics related to the number of first author and corresponding author highly cited articles. Top eight classic articles with total citations since publication to the end of 2014 more than 1000 times (TC2014 > 1000) and top eight classic articles with citations in 2014 more than 165 times (C2014 > 165) were selected and assessed regarding distribution of outputs in journals, publications of authors, institutions, as well as their citation life cycles. Solvothermal (including hydrothermal) method and diffusion (slow evaporation) were used mostly to prepare MOFs. Series representative MOFs, as well as the corresponding composites or film (membrane) arose the wide interests from researchers due to their excellent performances. Among the various properties and potential applications of MOFs, adsorption (gas adsorption and liquid adsorption) took the lead, followed by catalysis (including photocatalysis), as a result of their ultrahigh porosity and even their catalytic property. The results of Y index analysis revealed that most highly cited articles in MOFs field were contributed by Yaghi, O.M. as corresponding author, who published 27 articles with TC2014 (number of citations since its publication to the end of 2014) ź100. Omar M. Yaghi, as corresponding author (reprint author), contributed most classic articles, which dealt with synthesis strategy of MOFs with high porosity and high capacity of gas storage. The remaining classic ones concerned to catalysis and drug delivery. These classic articles were published in four high impact journals. The analyses on citation life cycles of the classic articles with highest TC2014 and C2014 can help the researchers in MOFs related fields gain insight into their impact histories.

Status and Impact of Acupuncture Research: A Bibliometric Analysis of Global and Brazilian Scientific Output from 2000 to 2014.

This bibliometric study was designed to evaluate the scientific output of Brazilian acupuncture publications and compare that output to the global trends in the same area. The analyzed data were retrieved from the online version of Science Citation Index Expanded (SCI-E) database and covered the period from 2000 to 2014. The documents were searched by using the topic filter to find acupuncture-related documents (ARDs) and the title filter for acupuncture-specific documents (ASDs). The analyzed categories included number of publications, type of documents, number of citations, universities/institutions, research areas, and journals. A total of 9301 ARDs and 5974 ASDs were published in the past 15 years worldwide. The global average number of citations per document was 10.61 for ARDs and 9.24 for ASDs. Brazil has published 252 ARDs and 169 ASDs, which corresponds to the tenth and ninth positions on the global correspondent rankings. The United States is the most productive country, with 2503 ARD publications, followed by China with 2143 and South Korea with 925. Norway is in the first position for the ARD citation rank, with 25.77 citations per document; Switzerland is in the first position for the ASD citation rank, with 26.66. Brazil has 4.19 citations per document, which corresponds to the 20th position in the ASD citation rankings. Evidence-Based Complementary Medicine, Acupuncture in Medicine, and The Journal of Alternative and Complementary Medicine are the leading journals in terms of numbers of ARDs and ASDs in Brazil and globally. The bibliometric analysis of the SCI-E database shows that global numbers of ARDs and ASDs and citations have constantly increased from 2000 to 2014. Brazil is among the top 10 most productive countries in the world in terms of number of acupuncture publications. However, the number of citations of Brazilian documents is below the global average.

Leadership of the present, current theories of multiple involvements: a bibliometric analysis

This review examines the current approaches to leadership by dividing them into two major categories: those that treat leadership as a hierarchical system and those that treat leadership as a complex, flexible framework. The innovation of the paper is in using a bibliometric analysis in order to observe whether our results bore a resemblance to what is known in the literature about the different approaches to leadership until now. The data sources for the analyses were the Science and Social Science Citation Index Expanded database and the World Catalog database. The main argument is that although transformational leadership still remains the most influential in this field of research, shared, complexity, and collective types of leadership are the approaches that show the next greatest intensity of research. A quantitate analysis of a bibliometric method supports this suggestion. We argue that the reason for their popularity in the field lies in the modern structure of Western society, with its shift from the Industrial Era to the Knowledge Era shaped by democratization, globalization, and growing complexity of modern society.

Viticulture and oenology scientific research: The Old World versus the New World wine-producing countries

The main aim of this study was to analyze the scientific productivity and collaboration between Old World wine-producing countries (Austria, Bulgaria, France, Germany, Greece, Hungary, Italy, Portugal, Romania, Spain, Switzerland) and New World wine-producing countries (Argentina, Australia, Brazil, Canada, Chile, Mexico, New Zealand, Peru, South Africa, United Sates, Uruguay) in viticulture and oenology through bibliometric analyses of articles included in the Science Citation Index Expanded database for the period 1994–2013. A number of 1527 research articles were published in 563 journals. The results highlight an important growth in the collaboration between countries during the second decade (2004–2013). Papers have been published in numerous journals belonging to several subject areas. Food Science and Technology, Horticulture and Biotechnology and Applied Microbiology appeared as the most productive research areas. A social network analysis of collaboration between these countries was also performed in order to analyze the most powerful scientific cooperation.

Productive capacity of fish habitats: a review of research development and future directions

Productive capacity of fish habitats (PCFH) is an important characteristic indicator to evaluating the impact of humans on fish habitats and the aquatic ecosystem. Using the bibliometric techniques and searching the Science Citation Index Expanded (SCI-Expanded) database from 1946 to 3/14/2014, this paper quantitatively reviewed the global research related to the PCFH, to predict important current and future research topics on this issue. Articles referencing the PCFH were analysed by accessing the following: document type and publication language, publication output characteristics, journal publication patterns, country and institution publication performance, author keyword, title words and Keywords Plus. The results confirmed that research on PCFH is becoming a notable area of interest. Current research emphases of PCFH are fish-habitat relationship and fish production, aquaculture techniques and fishery products, habitat conservation and fishery management, and climate change. Furthermore, six key areas of future research directions on PCFH were identified, namely: theoretical and technological basis, PCFH content, driving factors, calculation methods, ecosystem management and conservation strategies, and aquaculture. Moreover, it was suggest that a food web perspective should be considered in future fish habitat management and decision-making research. Basic data collection on fish and habitat is very urgent and important, and restoring the ecological function of fish habitats and damaged biological communities also represent important topics for future PCFH studies.

Circulating Resistin Levels and Risk of Colorectal Cancer: A Meta-Analysis.

Objectives. Published data on resistin levels in patients with colorectal cancer (CRC) were conflicting and heterogeneous. We conducted a meta-analysis of observational studies to examine the association of circulating resistin levels with carcinogenesis of the CRC. Methods. Potentially eligible studies published up to November 2015 were searched through MEDLINE, EMBASE, Science Citation Index Expanded database, CNKI, and WanFang database. The pooled weighted mean differences (WMDs) with 95% confidence intervals (CIs) calculated by fixed- or random-effect model were used to estimate the effects. Results. A total of 11 studies involving 965 patients were admitted in our meta-analysis. The pooled effects indicated that resistin levels were higher in CRC patients compared to healthy controls (WMD: 1.47 ng/mL; 95% CI: 0.78 to 2.16), with significant heterogeneity across the studies (I 2 = 72%, p < 0.0001). Subgroup analyses and sensitivity analyses revealed that study quality, design, sample type, and resistin assays may account for this heterogeneity. No publication bias was observed. Conclusions. Our meta-analysis suggests that increased circulating resistin levels are associated with greater risk of colorectal cancer. Given the limited number of available studies and significant heterogeneity, larger well-designed randomized studies are warranted.
