The publication impact of the first 100 THOR Network publications by bibliometric and social network analyses.

BACKGROUND: A specialized international multidisciplinary group of investigators wanted to determine the performance and impact of publications presented at an annual conference over a 6 year period. Specifically, the group wanted to know if the influence of the conference publications extended beyond conference publication authors and attendees. Bibliometric methods and network analyses were used to evaluate the performance and impact of 100 peer-reviewed publications presented at the Trauma Hemostasis and Oxygenation Research (THOR) Network Remote Damage Control Resuscitation (RCDR) Symposia from 2012 to 2017 (published 2013-2018). Further analysis was performed on the affiliations of conference attendees who attended from the years of 2012 to 2017. STUDY DESIGN AND METHODS: This project used normative and relative bibliometric measures and social network analysis to evaluate the performance and impact of 100 peer-reviewed publications presented at the Trauma Hemostasis and Oxygenation Research (THOR) Network RDCR Symposia from 2012 to 2017. Publication and citation data were from Elsevier Scopus, a bibliographic citation database. Metrics from Elsevier SciVal were selected for the project to normalize for group size, year of publication, and document type. A six-year period of publications presented at the Symposia, published from 2013 to 2018, was selected for analysis. The publication and citation data were further analyzed using Elsevier SciVal and the iCite database from the National Institutes of Health Office of Portfolio Analysis. Sci2, VOSviewer, and Gephi were used for social network analyses and visualization. RESULTS: The 100 publications presented at the Trauma Hemostasis and Oxygenation Research (THOR) Network Remote Damage Control Resuscitation (RCDR) Symposia from 2012 to 2017 demonstrate reach and influence beyond the authors of the THOR publications or the THOR attendees. Citations to the THOR publications were published in 10 languages and 313 unique journals, with author affiliations from 62 countries. Citation metrics for the THOR publications exceed global averages with 65% of the THOR publications being in the 25% citation percentiles. When benchmarking the THOR publications using six homogenous comparator groups, the THOR publications demonstrate higher citation metrics than any of the comparator groups with more citations per publication, a higher average of cited publications, higher FWCI and outputs in the top citation percentiles among the six groups. The Office of Portfolio Analysis (OPA) iCite database was used to calculate potential to translate for the THOR publications with 57 of the THOR publications cited by clinical articles with an average approximate potential to translate score of 65.3%. CONCLUSIONS: The value of international groups with sharing of research and knowledge are instrumental in enhancing the uptake for best practices for in medicine and treatment of hemorrhagic shock resuscitation. The use of bibliometric methods and network analyses, along with benchmarking, demonstrated reach and impact beyond the THOR Network. Limitations include use of a single source for analysis of publication and citation; and that publication data alone does not provide a full overview of research performance. Despite these limitations, bibliometric methods, social network analyses, and benchmarking can help centers better understand their impact.

Research evaluation support services in biomedical libraries.

Objective: The paper provides a review of current practices related to evaluation support services reported by seven biomedical and research libraries. Methods: A group of seven libraries from the United States and Canada described their experiences with establishing evaluation support services at their libraries. A questionnaire was distributed among the libraries to elicit information as to program development, service and staffing models, campus partnerships, training, products such as tools and reports, and resources used for evaluation support services. The libraries also reported interesting projects, lessons learned, and future plans. Results: The seven libraries profiled in this paper report a variety of service models in providing evaluation support services to meet the needs of campus stakeholders. The service models range from research center cores, partnerships with research groups, and library programs with staff dedicated to evaluation support services. A variety of products and services were described such as an automated tool to develop rank-based metrics, consultation on appropriate metrics to use for evaluation, customized publication and citation reports, resource guides, classes and training, and others. Implementing these services has allowed the libraries to expand their roles on campus and to contribute more directly to the research missions of their institutions. Conclusions: Libraries can leverage a variety of evaluation support services as an opportunity to successfully meet an array of challenges confronting the biomedical research community, including robust efforts to report and demonstrate tangible and meaningful outcomes of biomedical research and clinical care. These services represent a transformative direction that can be emulated by other biomedical and research libraries.

Gender Imbalance at Academic Plastic Surgery Meetings.

BACKGROUND: Participation in scientific meetings yields multiple benefits, yet participation opportunities may not be equally afforded to men and women. The authors' primary goal was to evaluate the representation of men and women at five major academic plastic surgery meetings in 2017. Secondarily, the authors used bibliometric data to compare academic productivity between male and female physician invited speakers or moderators. METHODS: The authors compiled information regarding male and female invited speakers from meeting programs. Bibliometric data (h-index, m-value) and metrics of academic productivity (numbers of career publications, publications in 2015 to 2016, career peer-reviewed publications, first and senior author publications) for invited speakers were extracted from Scopus and analyzed. RESULTS: There were 282 academic physician invited speakers at the five 2017 meetings. Women constituted 14.5 percent. Univariate analysis showed no differences in h-index, m-value, or numbers of total career publications or first and last author publications at the assistant and associate professor ranks, but higher values for men at the professor level. A model of academic rank based on bibliometric and demographic variables showed male gender significantly associated with increased probability of holding a professor title, even when controlling for academic achievement markers (OR, 2.17; 95 percent CI, 1.61 to 2.92). CONCLUSIONS: Although the impact of women's published work was no different than that of men among junior and midcareer faculty, women constitute a minority of invited speakers at academic plastic surgery meetings. Sponsorship is imperative for achieving gender balance within plastic surgery and to ultimately create more diverse and effective teams to improve patient care.

Impact of Jahnigen/GEMSSTAR Scholarships on Careers of Recipients in Emergency Medicine and on Development of Geriatric Emergency Medicine.

BACKGROUND: The Jahnigen Career Development Awards program was launched in 2002 with private funding and transformed into the Grants for Early Medical/Surgical Specialists' Transition to Aging Research (GEMSSTAR) program in 2011 through support from the National Institute on Aging and medical specialty professional societies. The Jahnigen/GEMSSTAR program has provided grants to early career physician-scientists from 10 surgical and related medical specialties to initiate and sustain research careers in the geriatric aspect of their discipline. From 2002 to 2016, there were 20 Jahnigen/GEMSSTAR recipients in emergency medicine (EM). The goal of this investigation was to examine the impact of Jahnigen/GEMSSTAR awards on careers of EM recipients and on development of academic geriatric EM. METHODS: We conducted an online survey of the 20 EM recipients from 2002 to 2016 and analyzed their academic productivity, research impact, career trajectory, and contributions to geriatric EM since receiving the award. RESULTS: All 20 Jahnigen/GEMSSTAR scholars completed the survey. Scholars have published a median of 33 peer-reviewed articles (interquartile range [IQR] = 10-97) since the award, with median annual publication rates of 4.5 (IQR = 1.6-7.0). All scholars had h-indices of 6 or more, with a median of 18 (IQR = 9-28). Jahnigen/GEMSSTAR scholars have served as principal investigator (PI) or co-PI on 126 grants since their award, with 90% having served as PI on at least one additional grant and 30% having received National Institutes of Health Career Development Awards. All scholars reported believing that the Jahnigen/GEMSSTAR was very helpful or helpful for career progress. Most (85%) reported ongoing contributions to geriatric EM in research, education, or administration. CONCLUSIONS: After the Jahnigen/GEMSSTAR award, EM scholars have been highly academically productive and successful, and the award has been instrumental in their career development. Awardees have been critical to the development of geriatric EM.

The Translational Science Benefits Model: A New Framework for Assessing the Health and Societal Benefits of Clinical and Translational Sciences.

We report the development of the Translational Science Benefits Model (TSBM), a framework designed to support institutional assessment of clinical and translational research outcomes to measure clinical and community health impacts beyond bibliometric measures. The TSBM includes 30 specific and potentially measurable indicators that reflect benefits that accrue from clinical and translational science research such as products, system characteristics, or activities. Development of the TSBM was based on literature review, a modified Delphi method, and in-house expert panel feedback. Three case studies illustrate the feasibility and face validity of the TSBM for identification of clinical and community health impacts that result from translational science activities. Future plans for the TSBM include further pilot testing and a resource library that will be freely available for evaluators, translational scientists, and academic institutions who wish to implement the TSBM framework in their own evaluation efforts.

Selection in a cyclical environment: possible impact of phenotypic lag on Darwinian fitness.

We investigated the effect of generation time (as controlled by chemostat flow rate) and temporal variability in nutrient (arginine) availability on selection at a regulatory locus in Escherichia coli. We first determined the fitness conferred by argR(K12) (which regulates the arginine regulon) relative to argR(B) (a weak constitutive) in constant environments at several generation times across a range of concentrations of arginine. The relative fitness of argR(K12) with respect to argR(B) declines with longer generation times in the absence of arginine yet becomes independent of generation time in the presence of excess arginine. Control experiments show this differential response in selection is entirely attributable to transcriptional regulation by argR(K12). Temporal variability in the supply of arginine generates fluctuations in selection. A simple model, based on the assumption that relative fitness tracks changes in arginine availability instantaneously, captures many of the features of the oscillating allele frequencies and accurately predicts the direction and intensity of selection in environments where arginine concentrations fluctuate frequently or infrequently. However, the model fails to predict the direction and intensity of selection in environments that fluctuate at moderate frequencies. This suggests that phenotypic lag, wherein cellular physiology changes more slowly than the environment, may be influencing the outcome of competition in this experimental system.

Fitness consequences of a regulatory polymorphism in a seasonal environment.

Gene regulation is commonly assumed to have evolved in response to environmental variability. Although tightly regulated in Escherichia coli strain K12, transcriptional control of arginine biosynthesis is deregulated in strain B. Caused by a single amino acid replacement in the arginine repressor, these contrasting regulatory strategies result in a fitness tradeoff. The K12 repressor is selectively favored in the presence of arginine and disfavored in its absence. In environments that cycle between high and low arginine, short seasons favor the K12 allele, whereas long seasons favor the B allele. Unexpectedly then, deregulated expression is adaptive in some seasonal habitats.
