A bibliometric and social network analysis perspective of X-ray phase-contrast imaging in medical imaging.

IntroductionPhase‐contrast imaging (PCI) is a novel technology that can visualise variations in X‐ray refraction (phase contrast) in addition to differences in X‐ray attenuation (absorption contrast). Compared to radiography using conventional methods (i.e. absorption‐based imaging), PCI techniques can potentially produce images with higher contrast‐to‐noise ratio and superior spatial resolution at the same or lower radiation doses. This has led PCI to be explored for implementation in medical imaging. While interest in this research field is increasing, the whole body of PCI research in medical imaging has been under‐investigated. This paper provides an overview of PCI literature and then focusses on evaluating its development within the scope of medical imaging.MethodsBibliographic data between 1995 and 2018 were used to visualise collaboration networks between countries, institutions and authors. Social network analysis techniques were implemented to measure these networks in terms of centrality and cohesion. These techniques also assisted in the exploration of underlying research paradigms of clinical X‐ray PCI investigations.ResultsForty‐one countries, 592 institutions and 2073 authors contributed 796 investigations towards clinical PCI research. The most influential contributors and network collaboration characteristics were identified. Italy was the most influential country, with the European Synchrotron Radiation Facility being the most influential institution. At an author level, F. Pfeiffer was found to be the most influential researcher. Among various PCI techniques, grating interferometry was the most investigated, while computed tomography was the most frequently examined modality.ConclusionsBy gaining an understanding of collaborations and trends within clinical X‐ray PCI research, the links between existing collaborators were identified, which can aid future collaborations between emerging and established collaborators. Moreover, exploring the paradigm of past investigations can shape future research – well‐researched PCI techniques may be studied to bring X‐ray PCI closer to clinical implementation, or the potential of seldom‐investigated techniques may be explored.

Foreign direct investment and economic growth: a dynamic study of measurement approaches and results

The relationship between foreign direct investment and economic growth (FDI-EG) has been subject to extensive research. The first document related to FDI-EG research in Web of Science was published in 1992 so that the research time is close to 30 years. This article aims to make a bibliometric study to measure the FDI-EG research from different points of view. 1,075 documents with respect to FDI-EG research were collected, and a strong bibliometric analysis was carried out by Bibliometrix software and review of approaches. The Bibliometrix software has revealed the leading researchers, conceptual structure, and thematic evolution of the FDI-EG research. At the same time, reviewing the literature helps to make content analysis, the most influential document analysis, co-authorship analysis, and citation and co-citation analysis. Amongst the findings, C. Chen, Journal of International Economics, and the USA are the most influential researcher, journal, and country, respectively. The FDI-EG research are focussed on the technology and firm performance, research modelling, and theoretical inquiry. More discussions are made in terms of current research status, avenues for future research, advantages and drawbacks of the methods. This article helps in understanding the evolution of the FDI-EG research from the perspectives of the bibliometric and review.

Rolf Zetterström: Discovered how bilirubin harms the brain in newborns with jaundice.

From the time I started school, I heard how brilliant Rolf Zetterström was from my father, who was also a paediatrician. Rolf had applied for a professorship in paediatrics at the Karolinska Hospital Children’s Clinic and was the favourite among the experts. He had among other things discovered how bilirubin harms the brains of newborns with jaundice. But the faculty likely considered him to be too young, which is why he was bypassed by the somewhat older Johnny Lind. As young as 38, Rolf was instead granted professorship at Gothenburg, where he quickly established distinguished research projects with adeptes such as Jan Winberg, Olov Celander and Johan Gentz. Four years later, he was called to the paediatric professorship at the Crown Princess Lovisa—later Saint Göran—Hospital. He had a fantastic ability to recruit research paediatricians, whereof several were from preclinical institutions. Several of them later became professors, such as Ove Broberger, Anita Aperia, Birgitta Strandvik, Ulla Berg, Agne Larsson and Gisela Dahlquist. Rolf was not just an influential researcher with over 400 publications but also a skilful clinician, who quickly could make the correct diagnosis in difficult cases. He was active for many years in the Nobel committee for physiology or medicine and the Royal Swedish Academy of Sciences. He was known in academic contexts for almost always asking relevant questions, if only after first giving a historical summary, before—in a somewhat crumpled way—reaching the point. For 40 years—between 1965 and 2005—he was editor-in-chief for Acta Paediatrica (Figure 1) and then continued as literature editor almost until his death in 2011. Owing to his encyclopaedic knowledge, he was competent to review articles within almost all paediatric subspecialties, even if he had associate editors to assist. I believe he read most of the articles himself and was very particular with the scientific quality. Manuscripts could be sent back and forth between the editorial office and the authors before they were accepted. Rolf was also recognised and respected internationally. It was therefore a challenge for me to succeed him in 2005, and he was not exactly happy to retire as editor-in-chief at 85 years of age. But we became very good friends. He came almost daily to the editorial office in an old villa between Karolinska Hospital’s main building and the Northern Cemetery. His office was cluttered with books and manuscripts. He continued to write, and engaged himself in all sorts of projects, on topics such as the environmental disasters around the polluted Aral Sea. I could always visit his office and discuss everything from Vitamin D, to BCG vaccination, to social paediatrics. He told me about several Nobel prize winners in physiology or medicine, which he had helped to judge. To a great extent, the conversations also surrounded the incompetence of most hospital directors. I was myself critical, but not nearly to Rolf’s degree. But when I met him in his later days, Rolf was not some hard authoritarian type of boss as the rumours went. He was then relatively humble and warm-hearted, and it was always rewarding to converse with him. The author has no conflicts of interest to declare.

I broke the glass ceiling, now what? Overview of metaphors to explain gender inequality in organizations

PurposeThis paper aims to identify and systematically summarize the relevant research on metaphors that are used to explain gender inequalities in the organizational context.Design/methodology/approachThe researchers conducted a systematic literature review using bibliometric techniques and content analysis.FindingsThe systematic literature review identified a total of 1,269 papers in 688 journals written by 2,441 authors. The first paper was published in 1971 and the publication growth can be observed in the five decades analyzed. The Gender in Management: An International Journal, was the journal that published more papers about this thematic. Michelle Ryan was the most influential researcher regarding the number of papers and citations she had. The content analysis performed with the 27 most influential papers showed 4 research streams (metaphors; gender and leadership; challenges, stereotypes and toxic environment; and gender in the academy). Concerning the metaphors explored in those papers, the glass ceiling is the most prominent. Furthermore, 26 kinds of barriers were identified regarding the challenges that women face to reach positions of power.Practical implicationsThe scrutiny of the metaphors and barriers enable access to what is being a hindrance to female progression in the organizational structure. So, this study may instrumentalize organizations and women to improve gender diversity practices in the workplace.Originality/valueThe value of the paper lays in the extensive literature review, using a bibliometric approach and content analysis.

Bibliometric mapping of mobile learning

This study aims to reveal the tendency towards research in the field of mobile learning with the analysis of co-authorship, bibliographic coupling, co-occurrence, and citation by taking into consideration of author, publication, keyword, journal, country, university and citation variables. As of September 2019, the meta-data of a total of 5167 studies in the Web of Science database constituted the scope of this study. VOSviewer and sciMAT were used for the bibliometric analysis while Harzing’s Publish and Perish software was used for the h-index. As a result of the bibliometric analysis, it was concluded that the most effective countries in mobile learning are Taiwan, USA, China, and England. According to the keyword co-occurrence analysis, mobile devices, higher education, mobile technologies, tablet, and smartphone keywords stand out in the field of mobile learning. Within the period of 2015–2019, trending topics were broadly educational technologies and, more specifically, tablets, mobile phones, MOOCs and learning strategies. It was found that G. J. Hwang is the most influential researcher and National Taiwan University of Science and Technology is the most influential university. It can be concluded that the most effective researches are augmented reality, higher education, and smartphone oriented mobile learning researches. According to the analyses conducted in the context of journals, Computers & Education, British Journal of Educational Technology and Educational Technology & Society were the most contributing journals.

Historical roots of Judit Bar-Ilan\u2019s research: a cited-references analysis using CRExplorer

Judit Bar-Ilan (JB) was an influential researcher in information science and scientometrics. She published more than 100 papers about different topics. We used the CRExplorer (see www.crexplorer.net) to investigate the historical roots of JB’s research. In this program, the N_TOP10 indicator is available. We applied this indicator to identify those publications which have been very frequently cited by JB during several citing years. These might be the publications by which JB was mostly influenced in her research. Our results show that the identified publications are seminal works in information science and scientometrics as well as methodologically oriented publications dealing with text or content analyses as well as influence or distance measures.

Zeigarnik and von Restorff: The memory effects and the stories behind them.

Two of the best known eponymous phenomena in memory research were carried out as dissertations in the same era at the same university, each supervised by an influential researcher working within the Gestalt framework. Both examined the influence of unexpected events on memory. Bluma Zeigarnik (Psychologische Forschung, 9, 1-85, 1927) first reported that memory is better for interrupted tasks than for completed tasks, a phenomenon long known as the Zeigarnik effect. Hedwig von Restorff (Psychologische Forschung, 18, 299-342, 1933) first reported that memory is better for isolated than for non-isolated pieces of information, a phenomenon long known as the von Restorff effect. In this article, I present: (1) a biographical sketch of the researcher behind each phenomenon, (2) a description of their dissertation research, and (3) an evaluation of the current status of each phenomenon.

Достоевский в Твиттере: лингводидактический взгляд на феномен твиттературы

The article examines the benefits of twitterfiction, a relatively new form of literary production, as a means of second language acquisition in the context of recreational reading. Pushed forward by the influential American educational researcher Stephen Krashen, free voluntary reading (FVR) has been proven to be an extremely powerful factor in developing various aspects of second language competence and getting students committed to reading more. This paper attempts to evaluate both quantitative and qualitative complexity measures of twitterfiction as in the case of TWITTERATURE by Alexander Aciman and Emmett Rensin to better understand the educational potential of the above type of prose. Readability formulas such as the Gunning Fog index and the Coleman-Liau index are deployed to evaluate the structural complexity of the text. ‘Attentive reading’, being a subjective factor in many ways, is a tool we apply to assess the text on the levels of semantics and pragmatics. The research concludes that twitterfiction, as demonstrated in the book, is an adequate ESL supplementary material alongside comics, graphic novels and level 4 graded readers.

The reception of Ivan Sikorsky’s scientific studies in the West

It is generally known that the influential Kyiv researcher, professor of the St. Volodymyr University and honorary member of the Kyiv Theological Academy Ivan Sikorsky (1842–1919) made a significant contribution to the development of the psychological science of his times and gained great authority among his colleagues in the West. In recent years, many studies have been launched in Ukraine, whose authors are trying to demonstrate the relevance of his work also in terms of contemporary science. It remains unclear as to when and how he was recognized in the West, which of his colleagues he influenced in his own life, how his academic achievements are now appreciated in foreign professional circles. Trying to fill this gap, the author of the paper created Sikorsky’s personal profile on the Internet platform “Google Scholar” (“Google Academy”). This Internet-based platform is regularly used to calculate citations of the contemporary scholars and publications. However, as it has turned out, Google Scholar may also be a useful tool for the historical research. This search engine collates information on almost all of the Sikorsky’s works, including those written or translated into foreign languages and published abroad. Despite the fact that Google Scholar identified and included in its own list not all of the existing references, it nevertheless helped to reconstruct a rather large and representative bibliography. Combining the quantitative and qualitative analysis of relevant information from Google Scholar as well as such tools as Google Books, Internet Archive, JSTOR, etc. helps to clarify and substantially expand the understanding of Sikorsky’s place within the history of science and the treatment of his works in the West. As it is clearly shown in the article, he became one of the brightest domestic representatives of the leading trends in the world psychology. A significant number of Western experimental psychologists of the late nineteenth and first half of the twentieth century (including such prominent figures as Alfred Binet, Franz Boas, Edouard Claparede, Edward Thorndike, etc.) were actively referring to his pioneering researches on the phenomenon of mental fatigue in children. It is also shown that the contribution made by Sikorsky to the development of psychology and pedagogy has not been forgotten by the contemporary researchers.Article received 26.08.2018

Fifty years of the American Academy of Pediatrics Section on Anesthesiology: a history of our specialty.

The American Academy of Pediatrics Section on Anesthesiology and Pain Medicine celebrated its 50th Anniversary in 2015. The Section was one of the first and only subspecialty organizations in anesthesiology at the time. This special article will focus on the contributions of the Section to the practice of pediatric anesthesiology in the areas of advocacy, education and member contributions. In 1986, the Section created the Robert M. Smith Award to honor those members who had made significant advances in the practice of pediatric anesthesiology. It is named after one of the Section founders, an influential educator, inventor, and researcher in our field. We will focus the latter part of the article on the Robert M. Smith award winners to illustrate the contributions of the Section and its members to the development of the field of pediatric anesthesiology.

Influential Researcher Identification in Academic Network Using Rough Set Based Selection of Time-Weighted Academic and Social Network Features

Researchers entering into a new research area are interested in knowing the current research trends, popular publications and influential (popular) researchers in that area in order to initiate their research. In this work, we attempt to determine the influential researcher for a specific topic. The active participation of the researchers in both the academic and social network activities signifies the researchers' influence level across time. The content and frequency of social interaction to a researcher reflects his or her influence. In our system, appropriate time-based social and academic features are selected using entropy based feature selection approach of rough set theory. A three layer model comprising semantically related concepts, researcher and social relations is developed based on the appropriate (influential) features. The researchers' topic trajectories are identified and recommended using Spreading activation algorithm. To cope up with the scalable academic network, map reduce paradigm has been employed in the spreading activation algorithm.

How to make opinion leaders and influence people.

At face value, a key opinion leader (or more commonly “KOL”) in medicine is an influential physician or researcher who is held in high esteem by their colleagues. The term originates from studies of influence in the 1940s by communications theorist Paul Lazarsfeld, who was skeptical about how

Environmental Governance and Technology: Opening the Black Box

Reducing greenhouse gas emissions to the levels needed to achieve climate stabilization – currently believed to be at least 60%, globally, by 2050 – will require many industries to undergo very rapid technical change directed toward sustainability. Theory and experience suggest that without well-considered environmental governance, the private sector will not reach its full innovative potential in this area. The three papers included in this symposium take different empirical approaches to build policy-relevant knowledge regarding the relationship between technical change and environmental governance. Following the presentations, Magali Delmas, a major contributor to the field of environmental governance, and Stuart Graham, an influential thinker and researcher in technical change, will lead an interactive group discussion of the papers as well as of the broader space for research in this important area.
