Knowledge mapping of skills mismatch phenomenon: a scientometric analysis

PurposeThis paper aims to understand the development track of skills mismatch research and discover the hidden internal connections between literature.Design/methodology/approachThe authors gathered data through scientometric quantitative analysis using CiteSpace. Specifically, this article applied basic analysis, journal cocitation analysis (JCA), author cocitation analysis (ACA) and document cocitation analysis (DCA), cluster analysis, citation burstness detection, scientific research cooperation analysis and coconcurrence analysis of keywords of 3,125 documents from Web of Science core collections for the period 2000–2020.FindingsThrough the document cocitation analysis and the keywords' co-occurrence, this article identifies influential scholars, documents, research institutions, journals and research hotspots in research on the skills mismatch phenomenon. The results showed that the publications had ballooned, and the phenomenon has become an interdisciplinary research subject. The USA and Finland remain the main contributors, which is attributed to their high-yield institutions such as the University of Helsinki, the University of Witwatersrand, the University of Washington and so on. While the African continent lacks research on skills mismatch even with the continent’s effort to overcome such a crucial issue. The paper presents an in-depth analysis of skills and educational mismatch issues to better understand the evolutionary trajectory of the collective knowledge over the past 20 years and highlight the areas of active pursuit.Research limitations/implicationsThe authors only used Web of Science core collection to collect data; however, they can added Scopus indexed database as well to extend the research trends and explore more new research hot topics to solve the skills mismatch phenomenon.Originality/valueThe scientometric analysis is of great significance for identifying the potential relationship between the literature and investigating the knowledge evolution of skills mismatch research. Organisation for Economic Co-operation and Development, the International Labor Organization and the World Health Organization are the giants who are mostly concerned of the mismatch skills phenomenon. Researchers can refer to this study to understand the status quo, gaps and research trends to deal with the skills mismatch issue.

Belief in Unconscious Repressed Memory Persists

On the basis of converging research, we concluded that the controversial topic of unconscious blockage of psychological trauma (i.e., repressed memory) remains very much alive in clinical, legal, and academic contexts. In his commentary, Brewin (this issue, p. 443) conducted a cocitation analysis and concluded that scholars do not adhere to the concept of unconscious repression. Furthermore, he argued that previous survey research did not specifically assess unconscious repression. Here, we present critical evidence that runs counter to his claims. First, we inspected his cocitation analysis and found that some scholars support notions that are closely related to unconscious repression. Furthermore, we conducted another analysis on the basis of articles’ similarity. Again, we found examples of scholars specifically endorsing unconscious repressed memories. Second, as opposed to what Brewin reports, recent survey research now exists that bears directly on people’s beliefs regarding unconscious repression. This work reveals that large percentages of people (e.g., students and eye-movement desensitization and reprocessing [EMDR] clinicians) endorse the concept of unconscious repressed memories. The belief in unconscious repressed memory can continue to contribute to harmful consequences in clinical, legal, and academic domains (e.g., false accusations of abuse).

Tilting at Windmills: Why Attacks on Repression Are Misguided

In the November 2019 issue of Perspectives, Otgaar et al. argued that the “memory wars” persist and that “the controversial issue of repressed memories is alive and well and may even be on the rise” (p. 1072). Their thesis overlooked the well-established consensus that recovered memories of trauma may be genuine, false, or a mixture of the two and instead focused on a disputed mechanism: unconscious repression. A formal cocitation analysis identified the major publications mentioning repressed memories, but none endorsed a theory of unconscious repression. Studies of beliefs about repressed memories by the general public and other groups do not support Otgaar et al.’s thesis either because these studies did not adequately assess the key ideas defining the theory of repression. Clinical evidence is consistent with recovered memories occurring in many different forms of therapy, including ones that do not use suggestive techniques or rely on the concept of repression. Thus, Otgaar et al. have proposed the existence of a problem for which little objective evidence can be found. Continuing theoretical uncertainties about the mechanisms responsible for forgetting are less important than the general recognition since the 1990s that suggestive therapy and attempts to exhume memories are hazardous and generally inappropriate.

Emerging Trends and New Developments in Transient Elastography: A Bibliometric and Cocitation Analysis from 1999 to 2017

Purpose. To identify and characterize the 100 most-cited articles in the field of transient elastography.Methods. The top-cited articles focusing on transient elastography from 1999 to 2017 were retrieved from Science Citation Index Expanded (SCI-E) database. The most prolific article, journal, country and continent, top-cited article in different period, international collaboration, cocitation analysis of journal were retrieved and analyzed in this article. Bibexcel 2016, Microsoft Excel 2010, and VOSviewer 1.6.5 were used to analyze bibliometric records we downloaded.Results. The 100 most-cited articles were published between 2003 and 2015. The total citations ranged from 54 to 1376 (mean, 167.52 ± 208.46; median, 89.5) and the annual citations ranged from 4.91 to 98.24 (mean, 17.21±15.68; median, 12.1). The top-cited article was published inGastroenterologyin 2005 by Castera L. et al. (n=1376). The most-cited articles in 2003-2007 (n=1380), 2008-2012 (n=599) and 2013-2017 (n=159) were located. All of the most-cited articles in three periods were focusing on the topic of noninvasive assessment of liver fibrosis. The most prolific author was de Ledinghen V. (n=21) and France (n=43) was the leading country. The most productive journal wasJournal of Hepatology(n=20). The major article type was original research article.Conclusions. We undertook efforts to provide an insight into the features and evolvement of the most-cited articles in the field of transient elastography. For transient elastography, as a noninvasive assessment of liver fibrosis, its use in the evaluation of liver fibrosis is gradually mature and shows great advantages. Moreover, the field of transient elastography is in a stage of rapid development.
