Purpose:Accurately assigning the document type of review articles in citation index databases like Web of Science(WoS)and Scopus is important.This study aims to investigate the document type assignation of review articles in Web of Science,Scopus and Publisher’s websites on a large scale.Design/methodology/approach:27,616 papers from 160 journals from 10 review journal series indexed in SCI are analyzed.The document types of these papers labeled on journals’websites,and assigned by WoS and Scopus are retrieved and compared to determine the assigning accuracy and identify the possible reasons for wrongly assigning.For the document type labeled on the website,we further differentiate them into explicit review and implicit review based on whether the website directly indicates it is a review or not.Findings:Overall,WoS and Scopus performed similarly,with an average precision of about 99% and recall of about 80%.However,there were some differences between WoS and Scopus across different journal series and within the same journal series.The assigning accuracy of WoS and Scopus for implicit reviews dropped significantly,especially for Scopus.Research limitations:The document types we used as the gold standard were based on the journal websites’labeling which were not manually validated one by one.We only studied the labeling performance for review articles published during 2017-2018 in review journals.Whether this conclusion can be extended to review articles published in non-review journals and most current situation is not very clear.Practical implications:This study provides a reference for the accuracy of document type assigning of review articles in WoS and Scopus,and the identified pattern for assigning implicit reviews may be helpful to better labeling on websites,WoS and Scopus.Originality/value:This study investigated the assigning accuracy of document type of reviews and identified the some patterns of wrong assignments. 展开更多

The Stockholm Convention on Persistent Organic Pollutants(POPs)is a legally binding instrument for 186 Parties(status:April 2023).Accordingly,among other responsibilities,countries are obliged to report the production,import,or export of the POPs listed in Annexes A,B,or C;provide information to registers;maintain inventories;and monitor the presence of POPs in the environment.In the broader context of international chemicals and waste management,producer responsibilities,harmonized reporting,and compliance with national and international regulations,Ecuador has addressed the newly listed group of perfluorinated alkyl substances(PFAS)in its national implementation plan and sent selected products from its national market for PFAS analysis.The products analyzed came from the initially listed fields of specific exemptions and acceptable purposes,including:fire-fighting foams;photographic aids;greasers/degreasers;various kinds of paper/packaging;textiles;and leather,coatings,cleaners,metal plating,and pesticides.Our results showed that the three PFAS presently listed in the Stockholm Convention could be quantified in only a few samples;additional PFAS,not yet listed in the Convention also had low detection frequencies.Although the number of samples was limited,the samples covered a large spectrum of sample matrices,making it possible to conclude that—once these products become waste and are regulated under the Basel Convention—they would not constitute a disposal problem.Nevertheless,verification of the presence of PFAS in products on the market is expected to pose an analytical challenge for both,developed and developing countries. 展开更多

Major media outlets have run many articles on the COVID-19 pandemic.Since the public suffers cognitive and emotional effects related to COVID-19 from such reports,we analyzed and reviewed the topics of news reports.We searched newspaper articles with the term‘COVID-19’term in four Korean daily newspapers from January 20,2020,when thefirst patient in Korea was found,to June 15,2020.Topic modeling analysis was conducted through text mining using R.Five themes were found:“Changes in people’s everyday life,”“Socio-economic shock,”“Trends in infection,”“Role of the government and business,”and“Increased psychological anxiety,”which all showed sharp increases in articles from mid-February to early March and then decreased.Despite the increased psychological anxiety people suffered from the COVID-19 pandemic,this topic showed the fewest articles.“Changes in people’s everyday life”showed the most,focusing attention on stimulating lifestyle articles of general interest.Since the COVID-19 pandemic can lead to mental health problems due to severe changes and isolation in everyday life,a comprehensive response to the news focusing on the impact on the mental health of the population around the world should be made. 展开更多

The acceleration of electrons near three-dimensional(3D)magnetic nulls is crucial to the energy conversion mechanism in the 3D magnetic reconnection process.To explore electron acceleration in a 3D magnetic null topology,we constructed a pair of 3D magnetic nulls in the PKU Plasma Test(PPT)device and observed acceleration of electrons near magnetic nulls.This study measured the plasma floating potential and ion density profiles around the 3D magnetic null.The potential wells near nulls may be related to the energy variations of electrons,so we measured the electron distribution functions(EDFs)at different spatial positions.The axial variation of EDF shows that the electrons deviate from the Maxwell distribution near magnetic nulls.With scanning probes that can directionally measure and theoretically analyze based on curve fitting,the variations of EDFs are linked to the changes of plasma potential under 3D magnetic null topology.The kinetic energy of electrons accelerated by the electric field is 6 eV(v_(e)~7v_(Alfvén-e))and the scale of the region where accelerating electrons exist is in the order of serval electron skin depths. 展开更多

Using the Raychaudhuri equation, we associate quantum probability amplitudes (propagators) to equatorial principal ingoing and outgoing null geodesic congruences in the Kerr metric. The expansion scalars diverge at the ring singularity;however, the propagators remain finite, which is an indication that at the quantum level singularities might disappear or, at least, become softened. 展开更多

Simultaneously manipulating multiple physical fields plays an important role in the increasingly complex integrated systems,aerospace equipment,biochemical productions,etc.For on-chip systems with high integration level,the precise and efficient control of the propagation of electromagnetic waves and heat fluxes simultaneously is particularly important.In this study,we propose a graphical designing method(i.e.,thermal-electromagnetic surface transformation)based on thermal-electromagnetic null medium to simultaneously control the propagation of electromagnetic waves and thermal fields according to the pre-designed paths.A thermal-electromagnetic cloak,which can create a cloaking effect on both electromagnetic waves and thermal fields simultaneously,is designed by thermal-electromagnetic surface transformation and verified by both numerical simulations and experimental measurements.The thermal-electromagnetic surface transformation proposed in this study provides a new methodology for simultaneous controlling on electromagnetic and temperature fields,and may have significant applications in improving thermal-electromagnetic compatibility problem,protecting of thermal-electromagnetic sensitive components,and improving efficiency of energy usage for complex onchip systems. 展开更多

By using ZHANG Qiao's method for identifying fuzzy words (1998), the present paper makes a statistic analysis of fuzzy words appearing in about 43,000 words of 6 academic research articles in management science. A distribution curve of fuzzy words in management research articles is drawn in accordance with the structures of the articles, and it is proved to be reasonable for tile discourse function of each section. Furthermore, the fuzzy words are divided into three categories and eleven sub-categories, including Category Ⅰ-fuzzy words, Category Ⅱ-fuzzy words+non-fuzzy part / non-fuzzy part+fuzzy words, Category Ⅲ-approximators+fuzzy words. Distribution of fuzzy words varies in different sections of research articles in management science, because of different communicative purposes or discourse functions. Introduction section and Conclusion section have a higher occurrence rate of fuzzy words than Abstract section and Methodology and Data section. 展开更多

Selection of an appropriate reporting verb and its tense & voice in a particular context is one of the best ways for the writer to present his work appropriately and to communicate effectively with others in the academic community.Previous studies on reporting verbs varied from sample to discipline,however,to my knowledge,no study has specifically addressed the question of whether there is tense and voice variation of reporting verbs in research articles in Introduction and Discussion in agricultural context.The present study is an attempt to investigate the tense and voice variation of reporting verbs and looks for explanations based on 30 agricultural science research articles.Results showed that no predominant tense choice was found in Introduction while simple past tense and present perfect tense were two tense preferences in Discussion.Active voice was found to be predominant in Introduction whereas passive voice was found to be predominant in Discussion. 展开更多

AIM: To identify the most-cited articles in ophthalmic epidemiology over the last decade.METHODS: We performed a cited reference search on articles that were included in the ISI Web of Science database using the terms "Epidemi*" AND "ophthalm*" AND "population*" during year 2006 to 2016. TOP 100 most cited articles(T100) in ophthalmic epidemiology were short listed and analysed using bibliometrics.RESULTS: These top 100 articles in ophthalmic epidemiology were cited between 61 to 333 times. Of these T100 articles, 36% originated from United States, and 34% were published in the Ophthalmology journal. The three major topics identified were age-related macular degeneration(AMD, n=23), glaucoma(n=16) and visual impairment(n=12). The top-cited article was a study on outdoor activities and its association with the prevalence of myopia in school-aged children, published in 2008. CONCLUSION: This bibliometric analysis provides useful insights into the current development in ophthalmicepidemiology in the past decade and can help recognizing the quality of the researches, discoveries, and trends steering ophthalmic epidemiology. 展开更多

AIM To identify and assess the research situation of top 100 cited articles in nonalcoholic fatty liver disease(NAFl D).METHODS The global scientific research articles in the science Citation Index-Expanded relevant to NAFl D were retrieved and listed according to their citation times from the most to the least. The 100 most frequently cited original articles were selected to systematically evaluate their bibliometric parameters including times cited, publication year, journals, subject categories, and the highly related concepts of NAFl D, which reflected the history and current situation, publication distribution of leading countries and institutes as well as the research hotspots of NAFl D.RESULTS Top 100 cited articles in NAFl D were published from 1965 to 2015 with a citation ranging of 227 to 2151 times since publication, in which the United states was the most predominant country and Mayo Clin was the most productive institution. The majority of the top 100 cited articles were concentrated in s CI subject category of Gastroenterology and Hepatology. Hepatology and Gastroenterology is the top journal that published over half 100 top-cited articles. The significant peak of top cited articles present in the first half of the 2000 s while the highest mean number of citation presents in first half of the 1980 s. In addition, concepts related to pathology characteristics, epidemiology and medicalization, metabolic syndrome and its combination of symptoms including insulin resistance, biomarkersof lipid metabolism and obesity are listed as the highly related concepts.CONCLUSION The 100 top-cited articles marked with the leading countries, institutions, journals, hotspots and development trend in NAFl D field that could provide the foundation for further investigations. 展开更多
