The Impact of Key Performance Indicators on Faculty Research in Higher Education

This study investigates the effectiveness of key performance indicators (KPIs) in evaluating the research contributions of academic staff in Uzbekistan, aiming to provide a nuanced understanding of faculty performance assessment. Employing a mixed-methods approach, the research integrates quantitative bibliometric analysis of publication data from 500 faculty members with qualitative interviews from 30 academics. The quantitative analysis focuses on metrics such as total publications, citation counts, and h-index scores, while the qualitative component explores faculty perceptions regarding the influence of KPIs on their research activities and career development. The analysis reveals significant variability in research productivity, with faculty averaging 12.4 publications and 110.2 citations. Econometric modeling indicates a strong positive correlation between publication metrics and citation impact, suggesting that higher publication output enhances academic visibility. Qualitative insights highlight the pressures of a "publish-or-perish" culture, which adversely affects research quality and faculty morale, particularly in contexts with limited institutional support. This research contributes to the discourse on academic performance evaluation by emphasizing the limitations of traditional metrics and advocating for a more holistic assessment framework. It highlights the need for higher education institutions to consider both quantitative and qualitative measures to better reflect the complexities of academic contributions in Uzbekistan.

Race, Ethnicity, and Gender Representation Among US Academic Spine Surgeons.

Although diversity has improved across certain orthopaedic subspecialties, enhancing diversity within spine surgery has remained a challenge. We aimed to investigate the current state of sex, racial, and ethnic diversity among academic orthopaedic spine surgeons in the United States. In January 2024, a cross-sectional analysis of orthopaedic spine surgery faculty in the United States was conducted using the Doximity database to identify eligible surgeons. Fellowship-trained orthopaedic spine surgeons (professor, associate professor, and assistant professor) who graduated residency between 1990 and 2022 were included. Race, sex, academic rank, residency year of graduation, and H-Index scores were recorded using publicly available information from faculty profile pages and the Doximity database. Four hundred fifty-two spine faculty were included in the analysis: 95.1% men and 4.84% women. Across race and ethnicity, 315 surgeons (69.7%) were White, 111 (24.6%) Asian, 15 (3.32%) Black or African American, and 11 (2.43%) Hispanic or Latino or of Spanish origin. Of the 101 professor-level surgeons, 3 (2.97%) were Black men. Among female professors, none were Black, Asian, or Hispanic/Latino. No Hispanic or Latino female professors, associate professors, or assistant professors were identified. The sex and race/ethnicity demographics that have increased in percentage over time include White women (0.92% to 6.08%), Asian men (11.0% to 26.5%), Asian women (0% to 1.66%), and Hispanic/Latino men (1.83% to 3.87%). The surgeon demographic groups that demonstrated minimal fluctuations over time included Black men, Black women, and Hispanic/Latino women. Our findings demonstrate that underrepresentation among academic spine surgeons remains an ongoing challenge that warrants increased attention. Enhancing the representation of Black and Hispanic men, as well as Black, Asian, and Hispanic women, in spine surgery requires a deliberate effort at every level of orthopaedic training.

Most influential women neurosurgeons on Twitter

BackgroundSocial media platforms can increase gender diversity and foster community within the neurosurgical field. Women have been historically underrepresented in neurosurgery. The purpose of this study is to compile a list of women neurosurgeons on Twitter according to their social media influence and identify whether social media influence correlates with academic productivity. MethodsWomen neurosurgeons (post-residency) in the United States who have Twitter accounts were obtained via the Women in Neurosurgery Twitter account and individuals who used the hashtag: #womeninneurosurgery (n= 50). Social media influence (followers, original posts, likes, retweets) was extracted through Popsters social media analytics platform for each of the accounts from January 1st, 2023 to June 30th, 2023. The efficiency metric standardized retweets for follower count, as well as number of posts. Academic H-index scores were ascertained via SCOPUS. 3 lists were created based off the efficiency metric, follower count, and average likes per post. ResultsThe relationship between the efficiency metric (average retweets per post per follower) and H-index was not significant at level of p < 0.05, whereas the relationships between follower count and H-index, and average likes per posts and H-index were significant at p < 0.05. ConclusionThe significant positive association found between H-index and average likes, as well as H-index and follower count demonstrates that social media influence and academic productivity/influence may go hand in hand. The lists of women neurosurgeons may serve as a guide for individuals interested in following women neurosurgeons on Twitter. Additionally, this would aid in fostering a community supportive of women neurosurgeons. Further, this may also inform individuals who would like to grow their presence on social media on how to build their following.

Cross-sectional examination of current and future trends and attributes of the presidents of the American Association of Neurological Surgeons and the Congress of Neurological Surgeons societies

ObjectiveThe present study aimed to analyze the academic attributes of the presidents of the American Association of Neurological Surgeons (AANS) and the Congress of Neurological Surgeons (CNS) over the past four decades to elucidate the trajectories of these societies' leaderships. MethodsForty-three AANS and 43 CNS presidents of the past four decades were identified. Demographic and research productivity data were collected from publicly available sources. ResultsCompared to AANS presidents, CNS presidents were younger (median = 48 years vs. 59.5 years; p < 0.001), had fewer years of practice prior to their election (15 years vs. 28 years; p < 0.001), had higher NIH funding rate (37.2% vs. 11.6%; p = 0.01), and higher rate of practicing at academic institutions (93% vs. 74.4%; p = 0.04). The CNS presidents had a comparable median number of publications at election (AANS: 72 vs. CNS: 94 publications, p = 0.78) but a higher median h-index scores (AANS: 28 vs. CNS: 59; p = 0.04). In the multiple linear regression analysis, vascular subspecialty (β = 0.21 [95% CI: 0.09–0.34]; p = 0.002) and practicing in a non-academic institution (β = 0.23 [95% CI: 0.08–0.39]; p = 0.007) were predictors for later election for AANS presidency. ConclusionsWe characterized the attributes of AANS and CNS presidents to serve as useful references for career trajectories for junior neurosurgeons and trainees. Research and academic presence seem to be associated with early election to both societies.

I forgot that you existed: Role of memory accessibility in the gender citation gap.

[Correction Notice: An Erratum for this article was reported online in American Psychologist on Sep 19 2024 (see record 2025-24490-001). The name of the author, Amy N. Arndt was incorrectly omitted from the author list in the original article. All versions of this article have been corrected.] Recent studies have found a citation gap in psychology favoring men. This citation gap is subsequently reflected in differences in h-index scores, a crude measure but important one for impact on career advancement. We examine a potential reason for the gap: that male researchers are more likely to come to mind than female researchers (i.e., a difference in memory accessibility). In a survey, faculty from psychology departments in R1 institutions in the United States listed up to five names they considered experts in their field and up to five names they considered rising stars (defined as pretenure) in their field. Results revealed that the proportion of female experts recalled by women generally matched the percentage of more senior female faculty at R1 institutions, whereas the proportion recalled by men was much lower as compared to this baseline. With rising stars, we observed both underrepresentation of women from male participants and, unexpectedly, overrepresentation of women from female participants, as compared to the percentage of more junior female faculty at R1 institutions. For both experts and rising stars, male names were also more likely to be generated earlier in lists by male respondents, but women did not vary in the order in which they listed women versus men. Despite the differences in recall observed in our data, there was no such gap in name recognition, suggesting that the gap is one of accessibility-who comes to mind. Implications and recommendations for psychology researchers are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Novel Journal Metrics in Cardiothoracic Surgery: How Different Are Contemporary Metrics From the Impact Factor?

Despite shortcomings, impact factor (IF) remains the "gold standard" metric for journal quality. However, novel metrics including the h-index, g-index, and Altmetric Attention Score (AAS; mentions in mainstream/social media) are gaining traction. We assessed correlations between these metrics among cardiothoracic surgery journals. For all cardiothoracic surgery journals with a 2021 Clarivate IF (N = 20), the 2-year IF (2019 to 2020) and 5-year IF (2016 to 2020), h-index, and g-index were obtained. Two-year journal-level AAS (2019 to 2020) was also calculated. Journal Twitter presence and activity was sourced from Twitter and the Twitter application programming interface. Correlations were assessed using Spearman correlation, and coefficients of determination were calculated. IF demonstrated a moderate-strong positive correlation with the h-index (rs = 0.48 to 0.77) and g-index (rs = 0.49 to 0.79) and a moderate correlation with AAS (rs = 0.53 to 0.58). The 2-year IF accounted for 25% to 49% of variability in the h-index, 27% to 55% of variability in the g-index, and 32% of variability in the AAS. Among journals with a Twitter account (N = 10), IF was strongly correlated with Twitter following (rs = 0.81 to 0.86), which was in turn strongly correlated with journal AAS (rs = 0.79). Article-level AAS was moderately correlated with citation count (rs = 0.47). IF accounted for only between 25% and 55% of variability in the h-index and g-index, indicating that these newer metrics measure unique dimensions of citation-based impact. Thus, the academic community must familiarize itself with these newer journal metrics. Social media attention may be associated with scholarly impact, although further work is needed to understand these relationships.

Breaking the unvirtuous cycle: barriers and opportunities for research and development in Paraguay. A case study.

Medical research and development (R&D) is an undoubtedly relevant activity to drive innovation, improve healthcare policies and bring patients treatment opportunities for common and rare diseases. Equity and inclusion are matters of concern in research. High-income countries' research teams are more likely to have more impactful publications, grant funding, and clinical trials than middle or low-income countries. Low budget allocations to R&D and existing gaps in regulatory frameworks are some obstacles to growth. This unvirtuous cycle results in scarce advances in common endemic diseases and the underrepresentation of specific populations in innovative therapeutics research. We conducted a policy review and qualitative research to determine the principal characteristics of basic and clinical medical research in Paraguay, as well as barriers and facilitators to improve innovative R&D strategies in this country. To this aim, we examined published articles from 2005 to 2020, the organizational structure of national research agencies, the current regulation framework, and the composition and experience of local research groups and ethical review boards (ERBs). In addition, we performed semi-structured interviews to evaluate perceptions and expectations from different stakeholders, including investigators, ERBs members, sponsor associates, and Regulatory Agency executive staff. In 2018, Paraguay ranked 10th out of 12 South American countries in total number of publications and cumulative h-index score. Total Gross Domestic Product (GDP) allocation for R&D was 0.15%, ranking eighth out of 12 in the region. In 2021, the number of trials registered on ClinicalTrials.gov was 52, with only 16 ongoing recruiting studies at that time.Some of the main barriers identified included low incentives for academic careers and lack of experience in pharmaceutical research. An emergent necessity to develop a straight- forward normative framework was detected. Main facilitators included the development of two research initiative programs (PRONII and PROCIENCIA) from CONACYT (National Council of Science and Technology) which were associated with higher budget allocation and total number of publications in the 2011 to 2017 period. A total of six stakeholders participated in the semi-structured surveys. Interviewees highlighted the necessity of a centralized policy to promote R&D, which incorporates investigators and ERBs training, the development of standardized procedures, and the dissemination of research activities. Sponsor associates underlined that real-world evidence may represent a distinctive opportunity to enhance local research. Coordinated efforts are needed to break the unvirtuous cycle. There is an increasing interest in enhancing health research in Paraguay, materialized in the creation of specific programs that encourage the collaborative work of healthcare providers, basic scientists, and private investors. Nonetheless, a comprehensive approach is needed also to strengthen regulatory agencies and attract external sponsorship. While modern and currently popular topics, including artificial intelligence, real-world data, and translational research may represent key opportunities to seek investment, special policies should be adopted to prioritize research on the determinants of health in the Paraguayan population.

Evaluating the Impact of Residency Research Productivity on Craniofacial Surgeons' Career Trajectory.

To elucidate trends in publication productivity over the past 50 years and how they correlate with the stage of training as well as the competitiveness of residency and fellowship programs. The authors hypothesize that research qualifications play an important role in obtaining a competitively ranked craniofacial surgery fellowship and that over the past 50 years, there has been an upward shift in the research qualifications held by applicants at the time of application. A cross-sectional study was performed involving all 121 academic craniofacial surgeons in the United States for whom sex, years since fellowship, current institution rank, current academic position, and years since graduation were available. The relationship between research qualifications, as determined by the overall number of publications, number of first authorship publications, H-index scores, and years since fellowship completion, was examined. The study also analyzed the placement of surgeons at programs ranked in the top 25 versus the lower 25. As the number of decades since beginning craniofacial fellowship decreased, the average number of first authorship publications and average H-index increased. Those who attended higher-ranking residency and fellowship programs had a higher average number of publications, number of first authorship publications, and H-index. Over the past 5 decades, research productivity at all stages of medical training has surged, potentially fueled by the trend toward pass/fail grading in medical school evaluations and standardized exams and the need to differentiate oneself in an increasingly competitive field.

Analysis of Research Productivity of Orthopedic Surgery Residency Applicants.

Background Orthopedic surgery has become an increasingly competitive specialty. With a pass-fail Step 1, an even greater emphasis on research has been placed to allow candidates to better distinguish themselves. This study analyzes the scholarly activity of accepted orthopedic residency applicants during medical school, assessing what factors, including the novel altmetric attention score, may be associated with greater research productivity. Methods A list of orthopedic residency programs was obtained from the Electronic Residency Application Service (ERAS). A total of 688 orthopedic residents from 180 programs who matriculated in 2020 from allopathic medical schools were identified.Resident demographic information and bibliometric data (total publications, orthopedic-related publications, h-index, and altmetric score)of publications published from July 1, 2016, toSeptember 1, 2020, were collected. Descriptive statistics were calculated. Kruskal-Wallis tests analyzed the association between medical school characteristics and research productivity using Stata® 17.0 (StataCorpLLC, College Station, Texas). Results Postgraduate-Year-3 orthopedic residents (N=688) published 2,600 articles during medical school, averaging 3.8 articles per resident. The residents from a top 25 medical school for research had publication counts, altmetric scores, and h-indices, on average, that were higher than those from non-top 25 medical schools for research. Over 150 residents had no publications, and ~10 residents had more than 30 publications. Conclusions The results illustrate that medical school research status influences the research productivity of applicants. Also, given the average number of publications, most research listed on applications are abstracts and presentations. Utilization of the altmetric score may not yet be the best way of examining research experience because orthopedic applicants do not appear to use social networks for academic research.

Indonesian Education Autonomy: A Bibliographic Study

This study aims to analyse the trend of educational autonomy in Indonesia. This study used a qualitative approach with a bibliometric analysis method. This study uses data from 2012–2022, sourced from the Google Scholar database and obtained using the Publish or Perish application. The data is then processed using the Vosviewer application to obtain a bibliometric map. The results of this study indicate that the study of Indonesian educational autonomy is quite attractive to researchers. Even though it fluctuated, in the span of the last decade, there were 205 papers on Indonesian education autonomy that had been cited 3075 times. From these figures, an h-index score of 11 and a g-index score of 55 are obtained. There are a total of 309 keywords, 1380 total link strengths, and 863 occurrences. These keywords are grouped into 79 clusters, with a varying number of keywords in each cluster. The keywords that dominate the study of Indonesian educational autonomy are: school based management, teacher, educational facility, education costs, and curriculum. In other words, the study of Indonesian educational autonomy focuses on these issues

Social science research: An analysis of BRICS countries

The purpose of this study is to conduct a quantitative analysis and comparison of social science research output among BRICS (Brazil, Russia, India, China, and South Africa) countries. Data were collected through the open-access SCImago portal and Scopus. The number of documents and citable documents, global share and ranking, the number of citations per document, the h-index, and international collaboration were all analyzed. Except for China, none of the BRICS countries made the top 10 global rankings during the 1996–2021 period, but three of them (China, India, and Russia) did so in 2021. China has the most documents and the greatest h-index score, whereas South Africa has the highest number of citations. For China, on the other hand, more than half of the citations are self-citations. More than 50% of Russian documents are not cited in the subsequent literature. The study’s findings highlight publication trends and collaboration pattern among the BRICS countries in social sciences, which benefit the academic community, decision-makers, and the economy of the BRICS countries.

Demographic and Academic Productivity Trends Among American Head & Neck Society Fellows Over a 20-Year Period

Historical data reveal that, compared with women, men are more likely to pursue a head and neck surgical oncology fellowship, but little is known about possible gender differences in academic productivity. To assess demographic trends and academic productivity among American Head & Neck Society (AHNS) fellowship graduates. This cross-sectional study used electronically published data from the AHNS on fellowship graduates in the US and Canada from July 1, 1997, to June 30, 2022. Scopus was used to extract h-indices for each graduate. Scholarly activity. Main outcomes were changes in demographic characteristics and academic productivity among AHNS graduates over time. Data analysis included effect size, η2, and 95% CIs. A total of 691 AHNS fellowship graduates (525 men [76%] and 166 women [24%]) were included. Over the study period, there was an increase in the number of programs offering a fellowship (η2, 0.84; 95% CI, 0.68-0.89) and an increase in the absolute number of women who completed training (η2, 0.66; 95% CI, 0.38-0.78). Among early-career graduates pursuing an academic career, there was a small difference in the median h-index scores between men and women (median difference, 1.0; 95% CI, -1.1 to 3.1); however, among midcareer and late-career graduates, there was a large difference in the median h-index scores (midcareer graduates: median difference, 4.0; 95% CI, 1.2-6.8; late-career graduates: median difference, 6.0; 95% CI, 1.0-10.9). A higher percentage of women pursued academic positions compared with men (106 of 162 [65.4%] vs 293 of 525 [55.8%]; difference, 9.6%; 95% CI, -5.3% to 12.3%). This cross-sectional study suggests that women in head and neck surgery begin their careers with high levels of academic productivity. However, over time, a divergence in academic productivity between men and women begins to develop. These data argue for research to identify possible reasons for this observed divergence in academic productivity and, where possible, develop enhanced early faculty development opportunities for women to promote their academic productivity, promotion, and advancement into leadership positions.

A mathematical analysis of the h-index and study of its correlation with some improved metrics: A conceptual approach

This article aims to establish the h-index in different mathematical aspects and measure the correlation of the h-index with other metrics using the bibliographic data of selected journals in the Library and Information Science (LIS) domain. Using the concept of relation and function, the h-index is expressed. Data collected from authors in three major LIS journals, including h-index, g-index, m-index, total citations and total publications, are analysed using correlation and regression analyses. The findings indicate a high level of relationship between h-index and g-index scores and m-index at starting year of publication. Conversely, a lower level of relationship between the h-index, g-index, starting year of publication, the total number of publications and the number of citations. This is an original study and will be of interest to the researchers of LIS who wants to know this performance indicator in different aspects, the dependency/independency of the h-index with other metrics, and the impact/performance of the three journals over time in terms of h-index, m-index, total citations and the number of publications. The study is limited to analysis of performance-and-citation-related measurements h-index, g-index, m-index, total citations, and the number of publications.

Indonesia's Open Government: A Bibliometric Analysis

This study aims to analyse trends and models of open government in Indonesia. This study uses a qualitative approach with bibliometric analysis methods and a systematic literature review. The data in this study were obtained from the Google Scholar database using the Publish or Perish application and processed using the Vosviewer application. The results of this study indicate that Indonesian open government studies are quite attractive to researchers. Although fluctuating, in the last decade there have been 52 publications on Indonesian open government studies, and 267 of them have been cited. From these figures, an h-index score of 10 and a g-index score of 15 are obtained. There are 83 keywords divided into 15 clusters, with the number of keywords in each cluster varying. Of these keywords, there are 412 links, 440 total link strength, and 132 occurrences. In 2020–2022, the Government of Indonesia established 18 policy models to support the achievement of open government. Since 2011 until now, the government of Indonesia has consistently supported the implementation of open government by establishing 152 policy models.

Academic productivity in Orthopaedic Traumatology correlates positively with industry compensation.

To determine the association between academic productivity and industry compensation amongst Orthopaedic Traumatologists. Retrospective cohort study. Review of the CMS Open Payments System from 2016-2020. One-thousand one-hundred twenty (N=1,120) Orthopaedic Traumatologists. To determine if an Orthopaedic Traumatologist's h-index and m-index, as generated from Web of Science, Scopus, and Google Scholar User Profile databases, correlate with total payments from medical industry in seven categories, including Royalties and Licensing Fees, Consulting Fees, Gifts, Honoria, and three unique Speaking Fee delineations. Of 30,343 Orthopaedic Surgeons in the Open Payments system, 1,120 self-identified with the Orthopaedic Trauma taxonomy. From 2016-2020, 499 (44.6%) surgeons received compensation in one of the eligible categories, most commonly from Consulting Fees (67.3%), though payments from Royalties provided the greatest gross income (70.4%). Overall, for all 1,120 surgeons, h-index (r=0.253, p<0.001) and m-index (r=0.136, p<0.01) correlated positively with mean annual total industry compensation. The highest annual compensation group had higher h-index ($0 vs $1-$1k vs $1k-$10k vs >$10k: 5.0 vs 6.6 vs 9.6 vs 16.8, p<0.001) and m-index ($0 vs $1-$1k vs $1k-$10k vs >$10k: 0.48 vs 0.60 vs 0.65 vs 0.89, p<0.001) scores than either the intermediate or no compensation groups. Multivariable analysis of factors associated with increased industry compensation, including H-index and years active, identified both as having significant associations with physician payments (H-index (B=0.073, p<0.001); years active (B=0.059, p<0.001)). Subgroup analysis of the highest annual earner group (>$250k/year) also demonstrated the highest overall h-index (27.6, p<0.001) and m-index (1.23, p=0.047) scores, even when compared to other high-earners ($10k-$50k, $50k-$250k). Overall, each increase in h-index above an h-index of 3 was associated with an additional $1,722 (95% CI: $1,298-2,146) of annual industry compensation. Academic productivity metrics have a positive association with industry compensation for Orthopaedic Traumatologists. This may highlight a potential ancillary benefit to scholarly efforts. Economic Level III. See Instructions for Authors for a complete description of levels of evidence.

Academic productivity metrics correlate positively with industry funding amongst orthopedic shoulder and elbow surgeons

Research efforts can produce practice-changing results with widespread implications for patient care. While critical to the advancement of the field, such efforts do not often provide direct compensation. However, a researcher's academic productivity may facilitate industry relationships, either as the impetus for the affiliation or a result of collaboration. Queries of the Centers for Medicaid and Medicare Services publicly available Open Payments System allowed for extraction of industry compensation data for orthopedic surgeons in 7 categories, including royalties and licensing fees, consulting fees, gifts, honoria, and 3 unique speaking fees delineations. This system identifies physicians by taxonomy identifications; however, Centers for Medicaid and Medicare Services does not have a unique code for shoulder and elbow surgeons. Therefore, identification of shoulder and elbow surgeons proceeded utilizing the American Shoulder and Elbow Surgeons (ASES) society 2019 membership directory. Cross-referencing this membership list with extracted Open Payments data provided industry funding information for all ASES members. Physicians then underwent an academic productivity assessment. Queries of Web of Science, Scopus, and Google Scholar User Profile databases provided the Hirsch index (h-index) and m-index for each surgeon. Bivariate and multivariate analyses produced statistical results. From 2016 to 2020, 631,130, 158, and 72 ASES members earned mean annual industry compensation <$1000, between $1001 and $10,000, between $10,001 and $100,000, and >$100,000, respectively. Royalties (91.5%) predominated in the top earning group, compared with consulting fees (58.0%, 55.0%) in the 2 middle-tier groups. H-index and m-index correlated positively with total compensation (h-index: r=0.18, P<.001; m-index: r=0.10, P<.001). The highest income group (>$100,000) had higher h-index and m-index scores than either intermediate ($1001-$10,000, $10,001-$100,000) or lowest (<$1000) compensation groups (From lowest to highest income bracket-h-index: 14.8 vs. 16.4 vs. 19.4 vs. 32, P<.001; m-index: 0.79 vs. 0.85 vs. 0.91 vs. 1.18, P=.003). Multivariable analysis of factors associated with increased industry compensation identified only h-index (B=8046, P<.001) as having a significant association with physician compensation, with each single unit increase in h-index associated with an 18% increase in industry funding. Among a group of academic shoulder and elbow surgeons, industry compensation correlates positively with academic productivity metrics, with an associated $8046/yr increase in industry funding for each single-unit increase in h-index over 9. Future studies may focus on more clearly defining the causal directionality of these results.

Analysis of H-index and Papers Citation in Computer Science Field using K-Means Clustering Algorithm

This paper provides an analysis of H-index and paper citations in the computer science field using K-Means Clustering Algorithm. By leveraging cutting edge visual analytics through the use of Power BI and Orange Data Mining tool with K-Means clustering algorithm, we are able to present a comprehensive review of how H-index and citations impact the scholarly evaluation of authors in computer science field.

The analysis conducted has revealed that area of research which has the highest value of citation and H-index include the following topics: Artificial-Intelligence, Computational-Intelligence, Data-mining, Evolutionary-Algorithms, and Big Data Analytics. Finally, the analysis of this research clearly demonstrated that paper citations remain an important factor for determining scientific impact in disciplines such as computer science given its close relationship with established metrics such as h-index scores.

Evaluation of the i10-Index in Plastic Surgery Research and its Correlation with Altmetric Attention Scores and Traditional Author Bibliometrics: An Evaluation of a Single Journal.

Background Although the Hirsch index (H-index) has become one of the most accepted measures of scholarly output, its limitations have led to the proposition of newer alternative metrics. The i10-index, notable for being easy to calculate and free to access, has potential, given its association with the power and ubiquity of Google. This study aims to evaluate the utility of the i10-index for plastic surgery research by examining its relationship with author bibliometrics and article metrics, including the H-index and Altmetric Attention Score (AAS). Methods Article metrics were extracted from articles published in the highest impact plastic surgery journal, Plastic and Reconstructive Surgery, over a 2-year period (2017-2019). Senior author bibliometrics, including i10-index and H5-index, were obtained from Web of Science. Correlation analysis was performed using Spearman's rank correlation coefficient (r s ). Results A total of 1,668 articles were published and 971 included. Senior author i10-index measurements demonstrated moderate correlation with times emailed (r s = 0.47), and weak correlations with H5-index, total publications, and sum of times cited with and without self-citations. The H5-index correlated very strongly with total publications (r s = 0.91) and sum of times cited (both r s = 0.97), moderately with average citations per item (r s = 0.66) and times emailed (r s = 0.41), and weakly with number of citations by posts, AAS, and times tweeted. Conclusions Although the i10 strongly correlates with the H5-index, it fails to prove superior to the H5-index in predicting the impact of specific research studies in the field of plastic surgery.
