The use of citation metrics for evaluation of individual researchers has dramatically increased over the last decade. However, currently existing indices either are based on misleading premises or are cumbersome to implement. This leads to poor assessment of researchers and creates dangerous trends in science, such as overproduction of low quality articles. Here we propose an index (namely, the L-index) that does not depend on the number of publications, accounts for different co-author contributions and age of publications, and scales from 0.0 to 9.9. Moreover, it can be calculated with the help of freely available software.

Object The application of bibliometric techniques to academic neurosurgery has been the focus of several recent publications. The authors provide here a detailed analysis of all active pediatric neurosurgeons in North America and their respective departments. Methods Using Scopus and Google Scholar, a bibliometric profile for every known active pediatric neurosurgeon in North America was created using the following citation metrics: h-, contemporary h-, g-, and e-indices and the m-quotient. Various subgroups were compared. Departmental productivity from 2008 through 2013 was measured, and departments were ranked on the basis of cumulative h- and e-indices and the total number of publications and citations. Lorenz curves were created, and Gini coefficients were calculated for all departments with 4 or more members. Results Three hundred twelve pediatric neurosurgeons (260 male, 52 female) were included for analysis. For the entire group, the median h-index, m-quotient, contemporary h-, g-, and e-indices, and the corrected g- and e-indices were 10, 0.59, 7, 18, 17, 1.14, and 1.01, respectively; the range for each index varied widely. Academic pediatric neurosurgeons associated with fellowship programs (compared with unassociated neurosurgeons), academic practitioners (compared with private practitioners), and men (compared with women) had superior measurements. There was no significant difference between American and Canadian pediatric neurosurgeons. The mean Gini coefficient for publications was 0.45 (range 0.18–0.70) and for citations was 0.53 (range 0.25–0.80). Conclusions This study represents the most exhaustive evaluation of academic productivity for pediatric neurosurgeons in North America to date. These results should serve as benchmarks for future studies.

This research aims to investigate whether multi/inter-disciplinary research activities are related to research impact and publication counts of scholars. Since researchers with very high levels of multi/inter-disciplinarity might be able to target complex problems, we would expect them to receive more credits than their colleagues with a stronger disciplinary orientation. We analysed Web of Science (WoS) indexed publications of all associate and full professors from a random sample of Australian universities in physics, chemistry and biology (1980–2014). Australian Fields of Research (FoR) codes assigned to journals were used to calculate the diversification of authors’ publications. The number of citations in the first 3 years, number of 10% most frequently cited papers, and citation impact percentile were used for impact assessment. A few indicators were used to measure the diversity including ‘extent of diversification (ED)’ (number of distinct FoR codes divided by the number of publications) and ‘diversification ratio (DR)’ (ratio of the publications falling outside the dominant code to the total number of publications). A total of 47.76% of biologists’ publications, 35.23% of physicists’ publications and 20.36% of chemists’ publications were published in journals assigned to fields other than the Australian associate and full professors’ fields. Publications from biologists had the largest values of diversification. Women (compared with men) and associate professors (compared with full professors) in chemistry, biology and overall were more probably to publish diversely. ED was negatively correlated with output and citation impact. DR also had a negative but weak correlation with the number of publications and 10% most frequently cited paper.

Background. This bibliometric analysis is aimed at reviewing the research pattern on the use of silver diamine fluoride (SDF) in dentistry using various citation metrics. Methods. A well-curated search was conducted on Elsevier’s Scopus database for the relevant literature on SDF published between 1969 and 2021. Bibliographic information such as information related to citations, bibliographic data, abstracts, keywords, and other relevant information was extracted using different combinations of keywords (“silver diamine fluoride” OR “Silver Diamine Fluorides” OR “Diamine Fluoride” OR “Silver Fluoride”). Analysis and visualization of the selected documents and related data were performed using various tools and software including MS Excel, MS Access, Bibexcel, VOS viewer, Biblioshiny, and Gephi. VOS Viewer was utilized for the Graph Modeling Language (GML) to generate graphical representations of the data. Furthermore, network graphs were generated to assess the various associations between research themes, countries, organizations, authors, journals, and citations. Results. The initial search yielded 662 documents, of which 410 were chosen for analysis. 252 records were deemed irrelevant. The chosen records consisted of journal articles ( n = 351 ), conference papers ( n = 14 ), book chapters ( n = 1 ), and review articles ( n = 44 ). The results showed that there was an upward trend in the research on SDF, and a substantial increase was observed in the citation index after 2014. Researchers from the United States of America, Hong Kong, and Japan were the top contributors, with organizations and authors from the Faculty of Dentistry, University of Hong Kong, leading the way in citations and productivity. Conclusion. The bibliometric analysis provides valuable information regarding the total number of publications on SDF and their citation details. It also identifies the leading countries and organizations involved in the research on SDF and provides a comprehensive analysis of the research trends related to SDF.

Acquired renal arteriovenous fistula is a rare complication following a nephrectomy and its diagnosis may be made many years after the intervention. The closure of the fistula is advisable in most cases, since it represents a risk for heart failure and rupture of the vessel. There are an increasing number of publications describing different techniques of occlusion. The case of a 70-year-old woman with abdominal discomfort due to a large renal arteriovenous fistula, 45 years after nephrectomy, is presented and current literature is reviewed. Percutaneous embolization was performed by placing an occluding balloon through the draining vein followed by the release of nine coils through arterial access. One day after successful occlusion of the fistula, clinical symptoms disappeared.

Abstract. Women have a minority position within science, technology, engineering, and mathematics and, consequently, are likely to face more adversities at work. This diary study takes a look at a facilitating factor for women’s research performance within academia: daily work engagement. We examined the moderating effect of gender on the relationship between two behaviors (i.e., daily networking and time control) and daily work engagement, as well as its effect on the relationship between daily work engagement and performance measures (i.e., number of publications). Results suggest that daily networking and time control cultivate men’s work engagement, but daily work engagement is beneficial for the number of publications of women. The findings highlight the importance of work engagement in facilitating the performance of women in minority positions.

The territorial image is formed both purposefully by the subjects of image-making, and spontaneously-based on the influence of information content published in various media. The purpose of the research is to analyze the image of the Republic of Mordovia in the information space of the Volga Federal district. The image of the territory formed by external target audiences by means of news materials is studied using the method of case study and content analysis of publications: “Volga news”, “Federal Press” news of the PFD, “Pravda PFD”. The authors conclude that modern reality is perceived through the prism of the information field created by mass media. The media creates images filled with certain data, facts, colored by emotions, on the basis of which representations, opinions, judgments, and assessments are subsequently formed. The media play a significant role in shaping the territorial image, especially for external target audiences who are not familiar with the region and do not have their own assessment knowledge and experience. Most of the information content about the Republic in the studied media is related to the main thematic blocks: politics, economy, social sphere, culture (art, sports). Moreover, if in the publications “Volga news” and “Pravda PFD” mention of the region prevails in the economic block, then in the publications “Federal Press” and “Nezavisimaya Gazeta” - in the political one. The Volga news publication significantly dominates the rest in terms of the number of publications about Mordovia. The content of publications is mostly positive and neutral related to the issues of economic development of the territory and the preparation and holding of the world football championship. Pravda PFD mentions the Republic in the context of news from neighboring territories, most of the publications date back to 2018, but here the context is related to the Republic's positions among the regions of the PFD in various ratings. The publication “Federal-Press” forms a generally reflective image of the territory, focusing on the negative aspects of regional life. “Nezavisimaya Gazeta”, giving priority to political news, maintains a neutral and reflective context of publications, paying attention to the key problems of the territory. Thus, the desired image of the region is counter-dictated to the image broadcast by the media through various information channels, so it is necessary to constantly monitor the information space and timely correction of the broadcast materials.

Genital endometriosis is a disease of women of reproductive age, accompanied by infertility in 50% [1]. Adenomyosis can be considered as an endometriosis of the uterus. Histologically, this process is represented by ectopic, non-tumor endometrial glands, and stroma surrounded by hypertrophic and hyperplastic myometrium [2]. Adenomyosis is accompanied by pelvic pain of varying intensity as well as menstrual disorders [1]. The disease is accompanied by significant violations of reproductive function (infertility, unsuccessful attempts at pregnancy and miscarriage, abnormal uterine bleeding). Adenomyosis can be accompanied by a violation of the function of adjacent organs (such as the bladder, rectum). Often, one of the clinical manifestations of adenomyosis is the development of sideropenic syndrome, which is also caused by the development of chronic post-hemorrhagic iron deficiency anemia. This is accompanied by a deterioration in the general condition of patients, a decrease in their ability to work. Despite a large number of publications in Russian and foreign scientific sources devoted to this problem, reproductive doctors and obstetricians-gynecologists often underestimate the role of adenomyosis in pregnancy planning using assisted reproductive technologies. Without interpreting the anamnesis data obtained through an active survey, doctors do not prescribe additional methods for diagnosing this pathology, which is not complex and expensive. To confirm the diagnosis, a transvaginal ultrasound examination of the pelvic organs during the premenstrual period is sufficient. In cases that are difficult to diagnose, the MRI method of the corresponding anatomical area can be used. Underestimation of the clinical picture and under-examination of the patient did not allow prescribing timely correction of the pathology and led to unsuccessful attempts to implement the generative function using assisted reproductive technologies. The conducted examination with clarification of the cause of IVF failures and the prescribed reasonable treatment made it possible to achieve regression of endometriosis foci in this clinical situation, followed by the patient's ability to realize generative function.
