INTRODUCTION: The acquisition of specialty-specific seminal literature and its application to daily, clinical patient-care decisions are critical components of clinical training. This structured, debate-style cardiothoracic surgery journal club module engages trainees in discussion of realistic patient scenarios, incorporating an extensive body of literature identified as the best evidence for the practice of cardiothoracic surgery. METHODS: We designed the structured, debate-style cardiothoracic surgery journal club and delivered it to University of Texas MD Anderson Cancer Center cardiothoracic surgery trainees. Overall assessment of knowledge acquisition consisted of both direct judging of debates by faculty facilitators and a year-end written test of trainee knowledge. Associated materials include guidelines and resources for faculty facilitators and trainees to prepare them for the journal club debate. Also included are cardiothoracic surgery patient cases, PowerPoint presentation slides, a debate score sheet, and multiple-choice knowledge tests with answer keys. RESULTS: Our structured, debate-style cardiothoracic surgery journal club is an effective educational intervention for cardiothoracic surgical trainees to gain practice in applying specialty-specific, literature-based evidence to particular patient problems. DISCUSSION: This resource may be used by course directors for surgery, for independent study by individuals planning to matriculate into surgical residencies, or as a review for those already in surgical training. Moreover, this curriculum can be delivered at other clinical training programs.
BACKGROUND: Evolution of surgical practice is influenced by publications in the leading journals of that field. If the authorship of a publication lacks geographical diversity, this could create bias and limit generalizability of the evidence. Accordingly, we conducted a geographical analysis of the leading Cardiothoracic Surgery journals worldwide. METHODS: Using 2020 Impact Factor, we searched the leading Cardiothoracic Surgery journals over the past decade. Only original articles were included. Data regarding first, second and last authors were extracted from every article. From this, we analysed country of affiliation, highest academic degree obtained and author location by metropolitan or rural setting. RESULTS: A total of 12,706 original articles were published in the top 5 ranked Cardiothoracic journals between 2011 and 2020. Authors originated from 69 countries, with the majority being from North America and Western Europe. The United States was the most common country of affiliation (42.8%) in all five journals, with New York City the most prominent city. A total of 63.7% of the authorship originated from large metropolitan areas (estimated as population greater than 500,000 residents), and the most common degrees obtained by authors were MD and PhD. CONCLUSION: The prominent Cardiothoracic authorship is predominantly located in Western countries, most commonly large metropolitan centers in the United States. This raises questions as to whether the literature adequately reflects populations in other geographical areas such as the continents of South America and Africa and rural settings. Leading journals should consider policies which encourage publication by authors from geographical locations that are underrepresented globally.

OBJECTIVE: We aimed to characterize chronologic trends of gender composition of the editorial boards of major cardiothoracic surgery journals in the current era. METHODS: A cross-sectional analysis was performed of gender representation in editorial board members of 2 North American cardiothoracic surgery journals from 2008 to 2023. Member names and roles were collected from available monthly issues. Validated software programming was used to classify gender. The annual proportion of women representation was compared to the thoracic surgery workforce. RESULTS: During the study period, 558 individuals (3641 names) were identified, 14.3% of whom were women. The total number of editorial board women increased for both journals. The proportion of women also increased from 2.5% (3 out of 118) in 2008 to 17.8% (71 out of 399) in 2023 (P < .001), exceeding the percentage of women in the thoracic surgery workforce, which increased from 3.8% in 2007 to 8.3% in 2021 (P < .001). The average duration of participation was longer for men than for women (53.8 vs 44.5 months; P = .01). Women in editorial board senior roles also increased from 3.3% (1 out of 30) in 2008 to 28.6% (42 out of 147) in 2023 (P < .001), almost triple the increase in nondesignated roles from 2.3% (2 out of 88) in 2008 to 11.5% (29 out of 252) in 2023 (P < .001). CONCLUSIONS: In recent years, the appointment of women to the editorial boards of high-impact cardiothoracic surgery journals and senior roles have proportionally exceeded the overall representation of women in cardiothoracic surgery. These findings indicate progress in inclusive efforts and offer insight toward reducing academic gender disparities.

I am honored by President Joachim Hasse and the European Association for Cardio-thoracic Surgery (EACTS) to have been invited to speak to you today. It is a special pleasure because to celebrate the millennium the Society of Thoracic Surgeons (STS) and EACTS are honoring one another, and the seeds for this coming together began on both sides of the Atlantic during the year I had the privilege of presiding at the STS. Why did I hope the language of science might be of interest to you? The EACTS, with English as its of®cial language, is one of the great international melting-pots of thoracic surgery. For many of you English is a second language, and I supposed that this might present you with more challenge in presenting your work than it would be to do so in your own languages. Why is this topic of interest to me? I was stimulated to think about differences between the research environment in the US and elsewhere when David Nahrworld sounded an alarm in 1995 with the observation that the number of publications from US authors in peer-reviewed surgical journals had been decreasing [1]. He said `The most striking ®nding was the dramatic, signi®cant fall in the number of1⁄4research pages from the US and the increase in1⁄4pages from countries other than the US1⁄4' Most of the American Surgical Association audience believed this re ected a decrease in time and funds allotted to research in the US. It took a French colleague, during the discussion period, to reassure us Americans and to make us chuckle. Professor Henri Bismuth of Villejuif, France responded by saying that this `1⁄4may re ect the increased ability of non-American surgeons to write English1⁄4It is like the French complaining of more Americans in French restaurants. It does not mean that French taste is losing.' John Waldhausen, editor emeritus of our sister journal, added perspective by saying, `1⁄4we should be thankful that these manuscripts are1⁄4in English rather than in Mandarin Chinese, the language spoken by more people than any other in the world.' Shortly after the Nahrwold±Bismuth±Waldhausen exchange that called attention to language, my interest was further stimulated when I lectured in Vienna. My offer to speak in Viennese German, my ®rst language, was politely declined in favor of English ± their of®cial language. I then realized how much more work it would have been for me to speak in my mother tongue than in my daily language. During the discussion period, which was in German, my audience understood better, and expressed itself more clearly and succinctly, in its own language than in English. This was true despite their sophistication and good knowledge of English. Subsequent visiting professorships in the Netherlands, France and Japan enhanced my awareness of the language burden faced by English second language scientists. My personal editorial experience for the Annals of Thoracic Surgery (ATS), the European Journal of Cardiothoracic Surgery, and a number of other journals has made me sensitive to today's topic. In addition, friends in Europe and Asia, who have impeccable skill in their own languages, have repeatedly asked me to review or edit manuscripts from the language viewpoint. Ladies and gentlemen, with native tongues other than English, my hat is off to you. You have accepted and coped admirably with an English language burden, and my hope is that you will see my remarks as constructive. I began my audacious venture into language studies by consulting the late Professor Victoria Fromkin, former chairperson of our UCLA Department of Linguistics. She reminded me that mathematics is the most durable language of science and she stressed a commonalty among written European Journal of Cardio-thoracic Surgery 18 (2000) 642±648
Although the presentation of original research to learned societies is valuable, the target should be publication in a peer-reviewed journal. Therefore, the strength of a meeting may be assessed by the rate of the subsequent publication of papers from the presented abstracts. We conducted an analysis of abstracts presented at consecutive annual meetings of the Society for Cardiothoracic Surgery (SCTS) in Great Britain and Ireland over a 15-year period. Abstract books and other documentation from the 1993-2007 meetings were reviewed; abstracts from other major Cardiothoracic Surgery meetings held in 2007 were also reviewed. Medline was searched to identify the peer-reviewed publications arising from each work presented. For abstracts presented at SCTS in 2003-07, the factors potentially associated with publication were analysed by logistic regression. If no publications were identified, authors were contacted through a standardized email questionnaire to ascertain its status and reasons for non-publication. Over the 15-year period, 909 abstracts were presented at the SCTS meetings. The rate of publication rose from ~30% in the mid-1990s to consistently >60% from recent meetings, with a high of 81.3% from 2006. However, in comparison with other Cardiothoracic Surgery meetings in 2007, the chance of subsequent publication from SCTS (66.7%) was lower than from the European Association for Cardio-Thoracic Surgery (75.0%), the American Association for Thoracic Surgery (83.9%) and The Society of Thoracic Surgeons (72.5%) meetings. For abstracts presented at the last five SCTS meetings, publication was most commonly in a speciality journal (56.3%) and the median time for publication was 15 months (range -24 to 63 months) with 14 papers published prior to presentation at the meeting. On regression analysis, the only factor associated with publication was the study design comparing randomized trials and systematic reviews with other types of study (P < 0.01). Of the 90 unpublished abstracts, 48 (53.3%) authors replied to an email questionnaire revealing that 41 (85.4%) were never submitted for publication. The most common reasons given were low priority (29.6%) and low likelihood of acceptance (24.1%). In recent years, the annual meeting of the Society has become a forum for the presentation of high-quality research that usually withstands peer-review, most commonly in a speciality journal. The rate of publication has increased to consistently >60%, although those that remain unpublished are generally never submitted. This compares favourably with national meetings of other surgical societies, although it is lower than other major cardiothoracic meetings which have an affiliated journal. At a time when it has been suggested that medical research in the UK is in decline, cardiothoracic surgery appears to be thriving.
We compare the network of aggregated journal-journal citation relations provided by the Journal Citation Reports (JCR) 2012 of the Science and Social Science Citation Indexes (SCI and SSCI) with similar data based on Scopus 2012. First, global maps were developed for the two sets separately; sets of documents can then be compared using overlays to both maps. Using fuzzy-string matching and ISSN numbers, we were able to match 10,524 journal names between the two sets; that is, 96.4% of the 10,936 journals contained in JCR or 51.2% of the 20,554 journals covered by Scopus. Network analysis was then pursued on the set of journals shared between the two databases and the two sets of unique journals. Citations among the shared journals are more comprehensively covered in JCR than Scopus, so the network in JCR is denser and more connected than in Scopus. The ranking of shared journals in terms of indegree (that is, numbers of citing journals) or total citations is similar in both databases overall (Spearman's \r{ho} > 0.97), but some individual journals rank very differently. Journals that are unique to Scopus seem to be less important--they are citing shared journals rather than bein
Rankings of scholarly journals based on citation data are often met with skepticism by the scientific community. Part of the skepticism is due to disparity between the common perception of journals' prestige and their ranking based on citation counts. A more serious concern is the inappropriate use of journal rankings to evaluate the scientific influence of authors. This paper focuses on analysis of the table of cross-citations among a selection of Statistics journals. Data are collected from the Web of Science database published by Thomson Reuters. Our results suggest that modelling the exchange of citations between journals is useful to highlight the most prestigious journals, but also that journal citation data are characterized by considerable heterogeneity, which needs to be properly summarized. Inferential conclusions require care in order to avoid potential over-interpretation of insignificant differences between journal ratings. Comparison with published ratings of institutions from the UK's Research Assessment Exercise shows strong correlation at aggregate level between assessed research quality and journal citation `export scores' within the discipline of Statistics.
This study examines the social media uptake of scientific journals on two different platforms - X and WeChat - by comparing the adoption of X among journals indexed in the Science Citation Index-Expanded (SCIE) with the adoption of WeChat among journals indexed in the Chinese Science Citation Database (CSCD). The findings reveal substantial differences in platform adoption and user engagement, shaped by local contexts. While only 22.7% of SCIE journals maintain an X account, 84.4% of CSCD journals have a WeChat official account. Journals in Life Sciences & Biomedicine lead in uptake on both platforms, whereas those in Technology and Physical Sciences show high WeChat uptake but comparatively lower presence on X. User engagement on both platforms is dominated by low-effort interactions rather than more conversational behaviors. Correlation analyses indicate weak-to-moderate relationships between bibliometric indicators and social media metrics, confirming that online engagement reflects a distinct dimension of journal impact, whether on an international or a local platform. These findings underscore the need for broader social media metric frameworks that incorporate locally dom
An exploratory, descriptive analysis is presented of the national orientation of scientific, scholarly journals as reflected in the affiliations of publishing or citing authors. It calculates for journals covered in Scopus an Index of National Orientation (INO), and analyses the distribution of INO values across disciplines and countries, and the correlation between INO values and journal impact factors. The study did not find solid evidence that journal impact factors are good measures of journal internationality in terms of the geographical distribution of publishing or citing authors, as the relationship between a journal's national orientation and its citation impact is found to be inverse U-shaped. In addition, journals publishing in English are not necessarily internationally oriented in terms of the affiliations of publishing or citing authors; in social sciences and humanities also USA has their nationally oriented literatures. The paper examines the extent to which nationally oriented journals entering Scopus in earlier years, have become in recent years more international. It is found that in the study set about 40 per cent of such journals does reveal traces of internati
Using the Scopus dataset (1996-2007) a grand matrix of aggregated journal-journal citations was constructed. This matrix can be compared in terms of the network structures with the matrix contained in the Journal Citation Reports (JCR) of the Institute of Scientific Information (ISI). Since the Scopus database contains a larger number of journals and covers also the humanities, one would expect richer maps. However, the matrix is in this case sparser than in the case of the ISI data. This is due to (i) the larger number of journals covered by Scopus and (ii) the historical record of citations older than ten years contained in the ISI database. When the data is highly structured, as in the case of large journals, the maps are comparable, although one may have to vary a threshold (because of the differences in densities). In the case of interdisciplinary journals and journals in the social sciences and humanities, the new database does not add a lot to what is possible with the ISI databases.
The journal structure in the China Scientific and Technical Papers and Citations Database (CSTPCD) is analysed from three perspectives: the database level, the specialty level and the institutional level (i.e., university journals versus journals issued by the Chinese Academy of Sciences). The results are compared with those for (Chinese) journals included in the Science Citation Index. The frequency of journal-journal citation relations in the CSTPCD is an order of magnitude lower than in the SCI. Chinese journals, especially high-quality journals, prefer to cite international journals rather than domestic ones. However, Chinese journals do not get an equivalent reception from their international counterparts. The international visibility of Chinese journals is low, but varies among fields of science. Journals of the Chinese Academy of Sciences (CAS) have a better reception in the international scientific community than university journals.
Overlay journals are characterised by their articles being published on open access repositories, often already starting in their initial preprint form as a prerequisite for submission to the journal prior to initiating the peer-review process. In this study we aimed to identify currently active overlay journals and examine their characteristics. We utilised an explorative web search and contacted key service providers for additional information. The final sample consisted of 34 overlay journals. While the results show that new overlay journals have been actively established within recent years, the current presence of overlay journals remains diminutive compared to the overall number of open access journals. Most overlay journals publish articles in natural sciences, mathematics or computer sciences, and are commonly published by groups of academics rather than formal organisations. They may also rank highly within the traditional journal citation metrics. None of the investigated journals required fees from authors, which is likely related to the cost-effective aspects of the overlay publishing model. Both the growth in adoption of open access preprint repositories and researcher
A number of journal classification systems have been developed in bibliometrics since the launch of the Citation Indices by the Institute of Scientific Information (ISI) in the 1960s. These systems are used to normalize citation counts with respect to field-specific citation patterns. The best known system is the so-called "Web-of-Science Subject Categories" (WCs). In other systems papers are classified by algorithmic solutions. Using the Journal Citation Reports 2014 of the Science Citation Index and the Social Science Citation Index (n of journals = 11,149), we examine options for developing a new system based on journal classifications into subject categories using aggregated journal-journal citation data. Combining routines in VOSviewer and Pajek, a tree-like classification is developed. At each level one can generate a map of science for all the journals subsumed under a category. Nine major fields are distinguished at the top level. Further decomposition of the social sciences is pursued for the sake of example with a focus on journals in information science (LIS) and science studies (STS). The new classification system improves on alternative options by avoiding the problem
Using three years of the Journal Citation Reports (2011, 2012, and 2013), indicators of transitions in 2012 (between 2011 and 2013) are studied using methodologies based on entropy statistics. Changes can be indicated at the level of journals using the margin totals of entropy production along the row or column vectors, but also at the level of links among journals by importing the transition matrices into network analysis and visualization programs (and using community-finding algorithms). Seventy-four journals are flagged in terms of discontinuous changes in their citations; but 3,114 journals are involved in "hot" links. Most of these links are embedded in a main component; 78 clusters (containing 172 journals) are flagged as potential "hot spots" emerging at the network level. An additional finding is that PLoS ONE introduced a new communication dynamics into the database. The limitations of the methodology are elaborated using an example. The results of the study indicate where developments in the citation dynamics can be considered as significantly unexpected. This can be used as heuristic information; but what a "hot spot" in terms of the entropy statistics of aggregated cit
Ageing of publications, percentage of self-citations, and impact vary from journal to journal within fields of science. The assumption that citation and publication practices are homogenous within specialties and fields of science is invalid. Furthermore, the delineation of fields and among specialties is fuzzy. Institutional units of analysis and persons may move between fields or span different specialties. The match between the citation index and institutional profiles varies among institutional units and nations. The respective matches may heavily affect the representation of the units. Non-ISI journals are increasingly cornered into "transdisciplinary" Mode-2 functions with the exception of specialist journals publishing in languages other than English. An "externally cited impact factor" can be calculated for these journals. The citation impact of non-ISI journals will be demonstrated using Science and Public Policy as the example.
INTRODUCTION: While there are no widely accepted diversity, equity, and inclusion (DEI) metrics for journals, geographic and sex diversity across a journal's editorial board may provide a surrogate measure of its commitment to DEI. We explored the association between journal quality and DEI metrics for cardiothoracic surgery (CTS) journals and investigated whether editorial diversity correlates with diversity across published articles. METHODS: We collected the following data for 30 CTS journals: country of publication (categorized by income level), journal quality metrics (citation-based metrics, e.g., impact factor (IF) or H-index), and sex and geographic representation across editorial boards and published articles. Bivariate correlations between numeric variables were assessed using Spearman's correlation. RESULTS: Female representation across editorial boards was 12.1%. Most editorial board members belonged to the United States (35.2%), with only 7.4% from the lower-middle-income countries and 0% from low-income countries. IF showed a strong positive correlation with female editorial representation (r = 0.70) but an inverse correlation with low- and middle-income countries (LMICs) editorial representation (r = -0.45). Female editorial representation demonstrated a significant positive correlation with female first authorship (r = 0.45), whereas LMIC editorial representation correlated strongly with LMIC corresponding authorship (r = 0.85). CONCLUSION: Women and researchers from LMICs are in the minority across editorial boards of CTS journals. However, a strong correlation between journal H-index and female editorial representation indicates that top-ranked journals are spearheading efforts to improve equitable sex-based and gender representations. Similar efforts are required to ensure more global geographic representation across editorial boards and top-ranked CTS journals are the best placed to lead by example.
For a nullhomologous Legendrian knot in a closed contact 3-manifold Y we consider a contact structure obtained by positive rational contact surgery. We prove that in this situation the Heegaard Floer contact invariant of Y is mapped by a surgery cobordism to the contact invariant of the result of contact surgery. In addition we characterize the spin-c structure on the cobordism that induces the relevant map. As a consequence we determine necessary and sufficient conditions for the nonvanishing of the contact invariant after rational surgery when Y is the standard 3-sphere, generalizing previous results of Lisca-Stipsicz and Golla. In fact our methods allow direct calculation of the contact invariant in terms of the rational surgery mapping cone of Ozsváth and Szabó. The proof involves a construction called reducible open book surgery, which reduces in special cases to the capping-off construction studied by Baldwin.
