An explorative study on document type assignment of review articles in Web of Science,Scopus and journals’websites

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.

Snapshot Survey of the Presence of Perfluoroalkyl Substances in Products, Articles, and the Environment in Ecuador

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.

Topic Models to Analyze Disaster-Related Newspaper Articles: Focusing on COVID-19

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.

Fuzzy Words Distribution in Management Science Research Articles

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.

The differences and similarities between the 2 sections in simple theme, multiple theme, textual theme, interpersonal theme, topical theme and thematic progression were analyzed and concluded. The author believes that the causes of the differences and similarities are the different genre features of the 2 sections and the academic features of the materials selected.

Rhetorical Structure of Research Article Methods in Agricultural Science

Currently,there has been a growing interest in the study of academic writing;focusing on the structural organization of academic text or specific linguistic features.However,very few studies have been done on the structural organization of the Methods and the linguistic features link to each move.Thus,the purpose of this study is to identify rhetorical structure of the Methods of agricultural science research articles and to explore the linguistic features linked to each identified move,by analyzing thirty research articles based on Kanoksilapatham's2005 framework.Altogether,five moves were found in the Methods,showing that rhetorical structure of Methods in agricultural science has its own format.The moves and linguistic features realizing rhetorical functions may help novice researchers or learners write the Methods of science research articles effectively and professionally.

An Investigation of the Misuse of English Articles of Chinese English Learners

English articles belong to a category of high frequency words. However, they also have been considered as one of the most difficult part and latest part to be fully acquired by non-native speakers. Because of this reason, a lot of efforts have been made to research into the acquisition of them. In China, researches on the article system were mainly focused on the analysis of functions and description of the usage. This essay intends to explore the distribution and features of English article errors made by Chinese EFL （English as a Foreign Language） learners both horizontally and longitudinally with the hope to find the possible factors which lead to the errors, so as to throw some light on English articles learning and teaching

An Empirical Study on Academic Writing of Applied Linguistics Articles

It has been suggested that Swales’create-a-research-space(CARS)model has had a tremendous influence on genre analysis in EAP and ESP and on the teaching of academic writing aiming at both L1 students or NNS students.In this essay,five RAs from TESOL Quarterly published from 1999 to 2001 will be analysed.The papers were selected because they were close in time and they had clearly defined and labelled introduction and conclusion sections.Based on CARS model,the paper will focus on structure of introductions and examine the link between introductions and conclusions by analysing the structure of conclusions.

Reporting Verbs in Agricultural Science Research Articles

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.
