L2 Vocabulary

This paper uses a co-citation analysis to examine the research on L2 vocabulary acquisition that was published in 1986. This year seems to mark a serious consolidation of L2 vocabulary research, with the main themes of future research appearing. The paper also reports a larger analysis of all the work that appeared in a five-year window from 1982-1986. This analysis clearly shows the beginnings of a recognisable research focus on L2 vocabulary acquisition, though this work is influenced by some surprising sources, who do not figure in more recent work in the field.

L2 Vocabulary

This paper uses a co-citation analysis to examine the research on L2 vocabulary acquisition that was published in 1985. This year seems to mark a kind of transition in the field. Unlike the earlier years analysed in this series of papers, 1985 shows signs of a coherent L2 vocabulary research front developing. The number of papers that qualify for inclusion is much greater than in previous years, and the analysis suggests that recognisable research themes are beginning to be clearly articulated.

L2 Vocabulary

This paper uses a co-citation analysis to examine the research on L2 vocabulary acquisition that was published in 1987. This year is surprisingly volatile compared with the previous year, 1986, with a very large number of new sources appearing in the maps, and many sources identified in previous years losing their influence in the research papers that make up the 1987 data set. The paper also reports a larger analysis of all the work that appeared in a five year window from 1983–1987. This larger data set is not quite as volatile as the smaller 1987 data set, but it suggests that some sources who dominated the co-citation maps in earlier years are losing their influence.

This paper uses a co-citation analysis to examine the research on L2 vocabulary acquisition that was published in 1988. Two analyses are presented. The first is a detailed account of the 1988 research on its own terms. The second analysis places this work in a larger context by looking at the research published in a five-year window covering 1984–88. The analyses identify important themes in the research and significant sources who are influencing the way the research is developing at this time. A particularly important new research theme centred around corpus linguistics appears in the 1988 data, and there are some surprising changes to the list of influential sources.

Background: Emerging evidence implicates the dysregulated kynurenine pathway (KP), an immune-inflammatory pathway, in the pathophysiology of mood disorders (MD), including depression and bipolar disorder characterized by a low-grade chronic pro-inflammatory state. The metabolites of the KP, an important part of the microbiota-gut-brain axis, serve as immune system modulators linking the gut microbiota (GM) with the host central nervous system.Aim: This bibliometric analysis aimed to provide a first glimpse into the KP in MD, with a focus on GM research in this field, to guide future research and promote the development of this field.Methods: Publications relating to the KP in MD between the years 2000 and 2020 were retrieved from the Scopus and Web of Science Core Collection (WoSCC), and analyzed in CiteSpace (5.7 R5W), biblioshiny (using R-Studio), and VOSviewer (1.6.16).Results: In total, 1,064 and 948 documents were extracted from the Scopus and WoSCC databases, respectively. The publications have shown rapid growth since 2006, partly owing to the largest research hotspot appearing since then, “quinolinic acid.” All the top five most relevant journals were in the neuropsychiatry field, such as Brain Behavior and Immunity. The United States and Innsbruck Medical University were the most influential country and institute, respectively. Journal co-citation analysis showed a strong tendency toward co-citation of research in the psychiatry field. Reference co-citation analysis revealed that the top four most important research focuses were “kynurenine pathway,” “psychoneuroimmunology,” “indoleamine 2,3-dioxygenase,” and “proinflammatory cytokines,” and the most recent focus was “gut-brain axis,” thus indicating the role of the KP in bridging the GM and the host immune system, and together reflecting the field’s research foundations. Overlap analysis between the thematic map of keywords and the keyword burst analysis revealed that the topics “Alzheimer’s disease,” “prefrontal cortex,” and “acid,” were research frontiers.Conclusion: This comprehensive bibliometric study provides an updated perspective on research associated with the KP in MD, with a focus on the current status of GM research in this field. This perspective may benefit researchers in choosing suitable journals and collaborators, and aid in the further understanding of the field’s hotspots and frontiers, thus facilitating future research.

AbstractThis paper provides an overview of the ever-increasing literature on opportunity recognition, with a focus on its antecedents and determinants. With a two-step research approach, a bibliometric analysis and a systematic literature review, we structure the current research in this field. By using bibliometric techniques, we analyzed 161 publications and, consequently, clustered the 30 most influential references. Apart from economic theories and the role of opportunity recognition in entrepreneurship, a strong research focus is on antecedents of opportunity recognition. Therefore, in our subsequent literature review, we focus on determinants which influence opportunity recognition. We find that the opportunity recognition process is influenced by various personal, organizational and environmental factors. We conclude with a research outlook for future research opportunities on opportunity recognition.

AIM: To identify and characterize the 100 most influential articles in the field of myopia over the last decades. METHODS: Articles on myopia published between January 1975 and March 2020 were searched through the Web of Science Core Collection database. Two independent authors reviewed and determined the 100 most cited articles. The characteristics of each eligible article were recorded, including authors, institutions, countries, journals, publication date, total citations (TCs), annual citations (ACs), research focus and article type. RESULTS: The top 100 most influential articles were published between 1983 and 2016, with 1999 as the most prolific year. The mean number of TCs was 288 (range: 193-537) and the mean number of ACs was 19 (range: 7-109). Treatment and epidemiology of myopia were the most important research focus. These articles were published in 21 journals led by Ophthalmology (29%) followed by Investigative Ophthalmology & Visual Science (23%). The number of ACs for articles published in the last ten years was significantly higher than that for the other most-cited articles (44 vs 16, Mann-Whitney U test P<0.01). There is no difference in the number of TCs between original articles and review articles, while the number of ACs for review articles was significantly higher than that for original articles (22 vs 17, Mann-Whitney U test P<0.05). CONCLUSION: This bibliometric analysis can provide us with concise information about the development trend of research in the field of myopia in the past few decades, and provide an important reference for researchers to guide future research.

Background: Possible applications of photoelectrocatalysis in the field of environmentally sustainable processes have inspired an exponentially increasing number of papers in the last decades. Less frequently, bibliometric analyses are presented, which are especially useful when a considerable amount of data is involved: metadata can be viewed from micro to macro perspective and may suggest ideas for future research. Objective: The objective of this study is to derive information on the research trends and to individuate possible gaps in specific topics, as well information on the authors and their related countries and institutes, and to quantify possible cooperation patterns between them. Methods: In addition to the classic data analyses immediately available on the database, such as the trend of the number of publications per year and the list of the most active authors or countries, the bibliometric analysis has been carried out using the VOSviewer software. Co-authorship and co-citation analyses have been performed, as well as co-occurrence of the keywords explicitly indicated by the authors. Results and Conclusion: Based on the publications in the SCOPUS database, the present work analysed the metadata relating to scientific articles published in the last two decades, dedicated to the research on photo-electrocatalytic processes and their possible application on wastewater treatment. Based on the list of the references present in the examined papers, the co-authorship analysis and the co-citation analysis also allowed the identification of the authors and the publications which have been most influential on the research on the examined topics. Indication has been obtained on the trend of the main topics investigated in time, as well as the current gaps in terms of content-wise and geographic cooperation.

The Way

This paper is the fourth instalment in a series of studies which attempt to plot the way research in L2 vocabulary acquisition has developed over the last fifty years. Earlier papers have analysed the research for 1982, 1983 and 2006 (Meara 2012, 2014, 2015). This paper follows on directly from my analysis of the 1983 research, and it uses the same bibliometric techniques that were used in the earlier papers: the co-citation methodology, first developed by Small (1973) and White and Griffith (1981). The analysis of the 1984 data shows some consolidation of the main research themes, but for the most part the L2 vocabulary research published in this year continues to be made up of small research clusters, sharing few common points of reference.

L2 Vocabulary

AbstractThis article reviews the literature of multimedia glosses in computer assisted language learning (CALL) and their effects on L2 vocabulary acquisition during the past seventeen years. Several studies have touched on this area to examine the potential of multimedia in a CALL environment in aiding L2 vocabulary acquisition. In this review, the researchers investigate the studies that deal with different modes of multimedia annotations in a CALL environment. This article reviews the empirical studies of multimedia glosses in reading as well as in listening comprehension activities and discusses the factors under which these studies have been conducted and their impact on L2 vocabulary acquisition. The study aims to understand how multimedia glosses have been used in the past to support second language vocabulary acquisition and also to explore any evidence regarding how multimedia glosses in a CALL environment can enhance the acquisition of L2 vocabulary. Only empirical studies (18 studies published in international refereed journals and conference) have been reviewed exclusively. The article discusses the findings of the reviewed studies and recommends future research.
