Recently, academic circles have raised concerns about academic citation partnerships. Many researchers receive emails offering these partnerships, often landing in their spam folders. In this paper, I refer to academic citation partnerships as unethical collaborative arrangements where researchers or authors agree to cite each other's work in their academic publications to enhance their academic profiles, often measured by metrics like the h-index. I discuss the characteristics of such partnerships, individuals, and groups who are commonly involved in academic citation partnerships, and clarify what is not considered an academic citation partnership. I argue that these partnerships are predatory and pose a serious threat to scholarly integrity. Such solicitations blur ethical boundaries by treating citations as commodities, similar to predatory journals and conferences. These partnerships compromise the authenticity of scholarly discourse, artificially inflate perceived impacts, and distort academic evaluations. They undermine the pursuit of knowledge for its intrinsic value and exacerbate inequalities in academia by favoring those who can manipulate citation metrics through resources or networks. Addressing this issue requires a commitment to vigilance and adherence to ethical citation standards, ensuring academic discourse that is intellectually honest and genuinely beneficial to academia.

Inspired by the popular h‐index in bibliometrics, the h‐accuracy index (HAI) was suggested as a new indicator to evaluate and compare errors in analytical chemistry. The HAI simultaneously considers the "trueness" of analytical measurements and the frequency of measurements with high "trueness". The HAI was defined as if the "trueness" of at most M% of the total measurements is no less than M%, the value of HAI will be M%, where a specific definition of "trueness" was given to compute the HAI. The range of the HAI was between zero and one. The HAI was applied to two examples as a new error index: (1) to evaluate and compare the analytical results by different methods/labs and (2) to evaluate and compare the prediction performances of different multivariate calibration models. Data analysis indicated that the HAI was a reasonable, robust, easy‐to‐compute, and comprehensive index for evaluating and comparing errors in analytical chemistry. Moreover, the HAI could provide the information about how many measurements are good. [ABSTRACT FROM AUTHOR]

Digital Libraries have emerged as an essential component of worldwide information infrastructure, adopting the latest Information and Communication Technology (ICT) to promote an organizational structure that encourages communication and resource sharing between academicians and researchers across the countries. The study explored global digital library literature that has been carried out in the years 2007-2021 based on various scientometric indicators such as publication output, prolific author, collaboration network by author, productive institution, and country. The key term "digital library" was used in our search strategy from the Web of Science. The data was saved and imported into R Studio and VOS viewer for analysis and illustration of our data. We accessed 5855 records retrieved from the Web of Science. The United States had the most documents published, followed by China and England. The journals of Electronic Library were ranked first. The University of California System was the top organization with many scientific publications with 5549 citations. This research gives scholars and practitioners a thorough overview of the key research issues and trends in digital library research worldwide. Digital libraries worldwide have impacted the research society. It is an extension of a physical library into an electronic library. This study is very significant in the current scenario to know the global growth rate of scientific literature. [ABSTRACT FROM AUTHOR]

Research productivity is on the rise as neurosurgical residency positions become increasingly competitive. We explored the relationship between neurosurgical residency applicant's senior author's research productivity and matching into a neurosurgery residency program. A retrospective analysis of bibliometric data for applicants who matched into neurosurgery in 2022–2023 and their senior authors was conducted using Scopus. Logistic regression revealed a significant association between h-index values and top 40 match outcomes (P = 0.038). The maximum h-index of senior authors significantly predicted matches at top 40 programs (P = 0.003). Affiliation with a top 40 medical school increased both applicant and senior author h-indices (P = 0.05, P < 0.001 respectively). Linear regression of the maximum h-index of senior authors in preresidency publications explained 42% of this variability (P < 0.001). A multiple linear regression model incorporating this with publication number elucidated 69% of the variance in interns' h-index. Authorship data categorized as first, second, and third author positions showed 1847 first author, 1417 second author, and 118 third author publications over 2-years. Applicants at top 40 residency programs had more first and second author publications compared to those from nontop 40 programs (P = 0.0158, P = 0.0275). There is a strong correlation between a neurosurgical applicant's academic output and that of their senior authors. The number of publications and the maximum h-index of senior authors significantly predict applicant h-indices. We also demonstrated that there is a significant difference in the academic productivity of applicants and senior authors of applicants who successfully match into a top 40 i(h)5 rated neurosurgical residency.

Orthopedic residency and fellowship applicants with a strong research record are highly valued for their potential in continuing academic excellence. Despite this, the association between research productivity during training and future academic productivity as an attending orthopedic surgeon is not well-established. We assess the effects of research output during different periods of surgical training as well as residency location on long-term academic productivity as an attending shoulder and elbow surgeon. A search of the 2022-2023 American Shoulder and Elbow Surgeons Fellowship Directory was conducted to identify a list of orthopedic shoulder and elbow fellowship faculty members. Each surgeon's residency, fellowship and current institution of practice were determined and stratified by geographic location. Total publication counts acquired before residency, during residency, during fellowship, and after fellowship were collected for each faculty member. Attending publication rates and H-indices were calculated. A multivariate linear regression model was created, and significance was set at a P value <.05. A total of 149 shoulder and elbow fellowship faculty members representing 34 fellowship programs were identified. The average number of total publications per surgeon was 88.8 ± 102. The average attending publication rate was 5.29 ± 6.89 publications per year. The average H-index for included surgeons was 27.8 ± 24.4. The number of publications acquired before residency (β = 0.293; P <.001), during residency (β = 0.110; P =.025) and during fellowship (β = 0.593; P <.001) were significantly associated with an increased attending publication rate, but no association was observed with the H-index [before residency (β = −0.221; P =.574), during residency (β = 0.045; P =.866), during fellowship (β = 0.198; P =.678)]. There were no significant differences in total publication count (P =.397), attending publication rate (P =.237), or H-index (P =.364) based on location of residency training. Research output before and during surgical training is predictive of continued academic productivity as a shoulder and elbow surgeon. In particular, greater productivity during surgical fellowship was most predictive of academic output as an attending. While long-term academic productivity does not seem to be influenced by the geographic location of residency training, attending surgeons practicing in the Midwest had significantly greater total publication counts and H-indices but similar annual publication rates.

Faculty productivity and influence constitute an important aspect of doctoral program quality. Literature on faculty productivity of Criminology and Criminal Justice (CCJ) Ph.D. programs has not yet properly weighted the impact of journal publications in a standardized and objective manner, limiting their analyses to select CCJ journals or the CCJ discipline. This is problematic because CCJ is an interdisciplinary field, and many criminologists publish in highly influential non-CCJ journals. While past assessments have largely neglected citation-based data, the present study analyzes scholarly productivity for the years 2015 to 2021 using a more comprehensive and inclusive method for assessing influence. Based on this study's productivity measure, the top programs are Florida State University, Pennsylvania State University, Arizona State University, the University of Pennsylvania, and the University of Cincinnati. Findings are situated with prior research and the latest U.S News and World Report rankings. [ABSTRACT FROM AUTHOR]

The Nobel Prize is an annual honor awarded to the researchers who have made the greatest contribution to humanity with their work in the year in question. Nobel Prizes for physiology or medicine and chemistry most often have direct or indirect pharmacological relevance. In this study, we performed a bibliometric analysis of Nobel Prize laureates from 2006 to 2022. The parameters include the nationalities and age of the laureates, age at their productivity peaks, the research locations, the H-index, the age-adjusted H-index, and the number of citations and publications, and, for each parameter, a comparison of female and male award laureates. Men were much more often awarded the Nobel Prize than women. Surprisingly, women were younger than their male colleagues at the time of the award although the productivity peak was similar. There was a correlation between all publications and the H-index, which was slightly stronger for women than for men. The age-adjusted H-index showed no difference among genders. The USA were the country with the highest number of Nobel Prize laureates, both male and female. Overall, the bibliometric characteristics of male and female Nobel Prize laureates are similar, indicating that among the group of Nobel Prize laureates, there is no bias against women. Rather, the achievements of women are recognized earlier than those of men. The major difference is that the number of women becoming Nobel Prize laureates is much smaller than the number of men. This study provides a starting for future studies with larger populations of scientists to analyze disparities. [ABSTRACT FROM AUTHOR]

Background: An individual’s research output is one of the important yardsticks in most western countries, which is one of the multiple parameters used to judge whether the person is suitable for an important position like the president of a medical associations or head of an institution. AIMS: We examined the research output of association and institutional heads in medicine in India to see how they compare with their counterparts in the United Kingdom (UK) and United States of America (USA). MATERIALS AND METHODS: Using the Scopus database, we compared the average of the numbers of publications, number of citations and h-index of the presidents of a number of medical associations and vice chancellors, directors or deans of academic medical institutions in India, UK and USA for the year 2021–2022. Results: The average number of publications from association presidents in India was 65, UK – 77 and the USA – 183, citations were 1355, 2407 and 10,955, and their h-indexes were 11, 19 and 39. The average number of research publications, citations and h-index of the heads of institutions in India, UK and USA was 98, 191 and 245, respectively; citations were 1171, 10,822 and 22,300 and h-index were 15, 47 and 67. Conclusions: Individuals holding important position in medical associations and institutions in the USA were ahead in their research output compared to those in the UK and India.

Objectives Our objective was to elucidate the demographic, academic, and career attributes of North American Skull Base Society (NASBS) presidents and determine how leadership of this society has changed over time. Design Thirty-one NASBS presidents have served between 1990 and 2021. Demographic and scholarly variables were recorded from publicly available sources. To determine how trends in NASBS presidents have changed over time, linear and logistic regressions were conducted on continuous and categorical variables, respectively. Setting Virtual setting was used for this study. Participants There were no active participants in the study. Main Outcome Measures Academic metrics of NASBS presidents were the main outcome measure. Results NASBS presidents had a mean age of 53.3 ± 6.1 years at election and were all male. The most common institution at which former presidents trained (n = 4) and practiced (n = 3) was the University of Pittsburgh. Otolaryngologists comprised 41.9% (n = 13) of the cohort, neurosurgeons made up 38.8% (n = 12), and the remaining 19.3% (n = 6) were from other specialties. NASBS presidents from neurosurgery (p = 0.033) and other specialties (p = 0.014) were more likely to hold the rank of chair compared with those from otolaryngology. Over time, there has been a linear increase in years of research experience at the time of election (p = 0.048). There remains a lack of diversity of gender and race. Conclusion NASBS presidents have demonstrated increased research activity over time, favoring long-term academic careers. Knowledge of these trends and attributes, which demonstrate an increase in skull base literature, growth of the NASBS, and a need for increased diversity in the field, is important for stewarding the future of the NASBS and promoting equity.

Objective: To investigate the relationship between the quality of YouTube videos on penile enlargement surgery and the scholarly profiles of surgeons. Materials and Methods: A YouTube search was conducted using the keyword “penile enlargement surgery”. Of the first 200 videos from the search results, 66 that met the study criteria were included in the analyses. Two urologists scored each video using the DISCERN score, the Journal of the American Medical Association (JAMA) score, and the global quality scale (GQS) in a double-blind manner. After the video quality scores were determined, the number of publications and h-indexes of surgeons were obtained from Google Scholar. Results: Of the videos, 31 (46.9%) were uploaded by plastic surgeons and 35 (53.1%) by urologists. The median duration of the videos was 4.1 min (interquartile range: 1-8.5) minutes. Eighteen (27.2%) videos had low quality, 9 (13.6%) had medium quality, and 39 (59.1%) had high quality. A statistically significant correlation was found between the h-index of surgeons and video quality scores (DISCERN, r=0.678; JAMA, r=0.646; GQS, r=0.689; p

This study investigates the impact of Free-to-Publish (F2P) versus Pay-to-Publish (P2P) models in dermatology journals, focusing on their differences in terms of journal metrics, Article Processing Charges (APCs), and Open Access (OA) status. Utilizing k-means clustering, the research evaluates dermatology journals based on SCImago Journal Rankings (SJR), H-Index, and Impact Factor (IF), and examines the correlation between these metrics, APCs, and OA status (Full or Hybrid). Data from the SCImago Journal Rank and Journal Citation Report databases were used, and metrics from 106 journals were normalized and grouped into three tiers. The study reveals a higher proportion of F2P journals, especially in higher-tier journals, indicating a preference for quality-driven research acceptance. Conversely, a rising proportion of P2P journals in lower tiers suggests potential bias towards the ability to pay. This disparity poses challenges for researchers from less-funded institutions or those early in their careers. The study also finds significant differences in APCs between F2P and P2P journals, with hybrid OA being more common in F2P. Conclusively, the study highlights the disparities in dermatology journals between F2P and P2P models and underscores the need for further research into authorship demographics and institutional affiliations in these journals. It also establishes the effectiveness of k-means clustering as a standardized method for assessing journal quality, which can reduce reliance on potentially biased individual metrics.

H-Index is a widely used metric for measuring scientific output. In this paper we showcase the weakness of this index as regards co-authorship. By ignoring the number of co-authors, each author gets the full credit of a joint work, something that is not fair for evaluation purposes. For this purpose we report the results of simulation scenarios that demonstrate the impact that co-authorship can have. To tackle this weakness, and achieve a more fair evaluation, we propose a few simple variations of H-index that consider the number of co-authors, as well as the active time period of a researcher. In particular we propose using HI/co and HI/(coy), two metrics that are simple to understand and compute, and thus they are convenient for decision making. The simulation shows that they can tackle well co-authorship. Subsequently we report measurements over real data of researchers coming from five universities (Cambridge, Crete, Harvard, Oxford and Ziauddin), as well as other datasets, that reveal big variations in the average number of co-authors. In total, we analyzed 526 authors, having in total more than 127 thousands publications, and 16.7 million citations. These measurements revealed big variations of the number of co-authors. Consequently, by including the number of co-authors in the measures for scientific output (e.g. through the proposed HI/co) we get rankings that differ significantly from the rankings obtained by citations, or by the plain H-Index. The normalized Kendall's tau distance of these rankings ranged from 0.28 to 0.46, which is quite high. [ABSTRACT FROM AUTHOR]

Gender-Based differences in h-indices across fields, including psychology, social work, and the biomedical sciences have been reported. These differences are persistent across all faculty ranks, including assistant, associate, and full professors, but may be larger for early career and senior faculty. Even with these known biases, the h-index remains a widely used metric of the productivity and impact of research scientists and university faculty. Recently, several studies have drawn attention to the potential for a widening gender gap in academic metrics given the ways in which gendered roles, and thus research productivity, were inequitably impacted by the COVID-19 pandemic. We describe the association between gender and h-index among a sample of tenured faculty from epidemiology departments in Schools and Programs of Public Health. Gender explained 1.2% of the variance in h-indices; after adjustment for professional age, gender explained only 0.1% of the variance. There was also crossover interaction for professional age and gender, with women having lower h-indices in early career yet overtaking males later. If h-indices are utilized as metrics for promotion and tenure, or as criteria for appointments to leadership or other roles, gender bias will continue to limit early- and mid-career women's inclusion and advancement.

A statistically significant correlation was found between the h-index of surgeons and video quality scores (DISCERN, r=0.678; JAMA, r=0.646; GQS, r=0.689; p<0.0001). There was also a statistically significant correlation between the total publication counts of surgeons and the video quality scores (DISCERN, r=0.614; JAMA, r=0.569; GQS, r=0.607; p<0.0001). Lastly, a weak, statistically significant correlation was detected between the DISCERN scores of the videos and the number of likes (r=0.278, p=0.029). Conclusion: This study revealed a significant correlation between the quality of YouTube videos on penile enlargement surgery and the h-indexes and total publication counts of surgeons. This study was the first to analyze the relationship between the quality of YouTube videos on penile enlargement surgery and the scholarly profiles of surgeons. [ABSTRACT FROM AUTHOR]

Objective: Bibliometric studies prepared by evaluating publication numbers, citation numbers and h-indexes are studies that show the production in the field of science. By conducting a study on pain medicine specialists in Türkiye, the study aimed to determine the Hirsch Index (h-index) ratings, number of citations, and number of publications ratings using the Scopus database and to assess the impact of the gender, institution, and title on these parameters. Methods: Pain physicians were identified via the Health Care Provider App Physician search tool, Council of higher education academic search tool, and websites of the institutions. This was followed by the determination of the h-index ratings, number of citations, and number of publications using the Scopus database. Results: Of the 274 pain physicians evaluated in the present study, 139 (50.7%) were female and 135 (49.3%) were male. The mean number of publications was 38.76 ± 32.53, the mean number of citations was 543.48 ± 987.16, and the mean h-index value was 9.51 ± 6.85. 173 (63.1%) of the algologists were working as professors, 16 (5.8%) as associate professors, 12 (4.4%) as assistant professors and 73 (26.6%) as specialist doctors. Of the total physicians, 173 (63.1%) were professors, 16 (5.8%) were associate professors. The mean of the number of publications and citations, and the mean h-index value of the professors were found to be significantly higher than those of other physicians (p<0.05). No significant difference was found between the male and female pain physicians with respect to these parameters (p>0.05). Conclusion: Our study is the first in our country to evaluate the number of publications, number of citations and hindexes, which are important bibliometric parameters that show the scientific production of algologists. It was determined that the number of female pain physicians was higher, whereas the publishing activities and mean h-index values of male academicians were higher. Nevertheless, there were no significant differences between the genders. [ABSTRACT FROM AUTHOR]

Purpose: This study provides a bibliometric analysis of bank efficiency and competition over the past years (from 1993 to 2022) to (1) discover the past and current state of knowledge on bank competition and efficiency, (2) identify leading and authoritative journals and scholars who made significant contributions to the distribution of knowledge and impact, (3) identify nations that made a significant contribution and impact to the literature and (4) identify the structure of collaboration that exists between scholars in the areas of bank competition and efficiency and key thematic areas. Design/methodology/approach: A total number of 868 documents made up of articles, reviews, book chapters, book and conference papers from the Scopus database were gathered. This study used a bibliometric analytic approach. Findings: The number of documents on bank competitiveness and efficiency has increased significantly, as have their total publications, citations and national output. Additionally, the most esteemed and prestigious academic journals of eminent academics who have had a significant impact on the dissemination of knowledge on bank efficiency and competition literature champion papers on banking efficiency and competition. In terms of citation performance and collaborative efforts, the United States tops the developed countries, led by China, which is also the most productive. Additionally, single-country publications predominate in the literature, with China ranking first among the top five countries with corresponding authors. While the Lerner index, H-statistic, concentration index and market power were used to measure bank competitive behaviour, the data envelopment analysis approach predominates efficiency estimation techniques that are linked to cost, profit or revenue, scale, technical and productivity indexes. Originality/value: This study is one of the first to offer bibliometric evidence of both bank competition and efficiency. It also offers proof of the distribution of knowledge and intellectual structure of the concepts and concerns in bank competition and efficiency. [ABSTRACT FROM AUTHOR]

This paper measures two main inefficiency features (many publications other than articles; many co-authors' reciprocal citations) and two main inequity features (more co-authors in some disciplines; more citations for authors with more experience). It constructs a representative dataset based on a cross-disciplinary balanced sample (10,000 authors with at least one publication indexed in Scopus from 2006 to 2015). It estimates to what extent four additional improvements of the H-index as top-down regulations (∆Hh = Hh − Hh+1 from H1 = based on publications to H5 = net per-capita per-year based on articles) account for inefficiency and inequity across twenty-five disciplines and four subjects. Linear regressions and ANOVA results show that the single improvements of the H-index considerably and decreasingly explain the inefficiency and inequity features but make these vaguely comparable across disciplines and subjects, while the overall improvement of the H-index (H1–H5) marginally explains these features but make disciplines and subjects clearly comparable, to a greater extent across subjects than disciplines. Fitting a Gamma distribution to H5 for each discipline and subject by maximum likelihood shows that the estimated probability densities and the percentages of authors characterised by H5 ≥ 1 to H5 ≥ 3 are different across disciplines but similar across subjects.

This study examines the influence of National Institutes of Health (NIH) funding on the publication choices of dermatologists, particularly in terms of journal tiers and pay-to-publish (P2P) versus free-to-publish (F2P) models. Utilizing k-means clustering for journal ranking based on SCImago Journal Rank, h-index, and Impact Factor, journals were categorized into three tiers and 54,530 dermatology publications from 2021 to 2023 were analyzed. Authors were classified as Top NIH Funded or Non-Top NIH Funded according to Blue Ridge Institute for Medical Research rankings. The study finds significant differences in publication patterns, with Top NIH Funded researchers in Tier I journals demonstrating a balanced use of P2P and F2P models, while they preferred F2P models in Tier II and III journals. Non-Top NIH Funded authors, however, opted for P2P models more frequently across all tiers. These data suggest NIH funding allows researchers greater flexibility to publish in higher-tier journals despite publication fees, while prioritizing F2P models in lower-tier journals. Such a pattern indicates that funding status plays a critical role in strategic publication decisions, potentially impacting research visibility and subsequent funding. The study’s dermatology focus limits broader applicability, warranting further research to explore additional factors like geographic location, author gender, and research design.

AIM: To analysis of research hotspots and trends on the application of premium intraocular lens (PIOLs) in the past 2 decades. METHODS: The literature search was performed on the Web of Science and included PIOLs studies published between January 2000 and December 2022. The retrieved literature was collated and analyzed by R-tool's Bibliometrix package, CitNetExplorer, CiteSpace and other software. RESULTS: A total of 1801 articles about PIOLs were obtained, most of which were published in Spain and the United States. The organization that published the most articles was the University of Valencia in Spain. Alió JL, and Montés-Micó R, from Spain were the most influential authors in this field. The Journal of Cataract and Refractive Surgery and Journal of Refractive Surgery were the core journals for this field; the top 10 cited articles mainly focus on postoperative satisfaction with multifocal intraocular lens (IOLs) and postoperative results of toric IOLs. Through the keyword analysis, we found that trifocal IOLs, astigmatism and extended depth of focus (EDoF) IOLs are the most discussed topics at present, and the importance of astigmatism and the clinical application of the new generation of PIOLs are the emerging research trends. CONCLUSION: Bibliometric analysis can effectively help to identify multilevel concerns in PIOLs research and the prevailing research trends in the realm of PIOLs encompass the adoption of EDoF IOLs, trifocal IOLs, and their respective Toric models.

Accurate identification of influential nodes in complex networks is crucial for network management and network security.The local centrality method is concise and easy to use, but ignores the topological relationship between neighboring nodes and cannot provide globally optimal results.A node importance assessment method was proposed to correlate the node edge relationship and topology, which firstly applied the H-index and information entropy to assess the nodes, then combined the structural holes of the nodes with the structural characteristics of the nodes, and took into account the attribute of “bridging” while focusing on the node’s own quality and the amount of information about the neighboring nodes.The algorithm was validated by simulating the propagation process using the SIR model, and the Kendall correlation coefficient, complementary cumulative distribution function and propagation influence were applied to validate the validity and applicability of the method.Comparison of the experimental results on six real network datasets shows that the proposed method is more accurate than the traditional centrality methods in identifying and ordering the key nodes in the network.

1. IntroductionConsidering that the goal of social science research is to train and provide skilled and specialized human resources to carry out research, education, management and planning in various social and cultural fields, and also considering that the main emphasis of this field is the education and promotion of excavations. A field about the social issues of the country and the analysis and interpretation of their roots, contexts, causes and factors, description and analysis of their extent in the society and finally the analysis of the information obtained from these studies is to solve social issues, therefore providing considered solutions to deal with them. With these problems and social developments, it is necessary. Considering that one of the evaluation criteria of universities and countries is the quantity and quality of their research outputs in international reliable databases. The status of each country's indexed research outputs in international valid indexes indicates an important part of that country's scientific activities at the international level. Therefore, in order to analyze scientific activities, a clear picture of this situation has always been the focus of the country's research managers. Therefore, it is necessary to pay attention to the quality of research outputs in Iranian universities, which are considered the most important scientific hub of the country. The results of this research can be used for planning at the level of administrations, various vice-chancellors and the entire universities under review, and by knowing the priorities, abilities and weaknesses, provide the necessary facilities to make scientific activities more targeted in the subject areas of social and behavioral sciences in the universities under review. Therefore, this research studies and analyzes the research outputs of Iran's major universities using qualitative Scientometrics indicators in the subject areas of social and behavioral sciences during the period of 2010-2020.Research QuestionWhat is the status of the research outputs of Iran's major universities in the subject areas of social and behavioral sciences with a Scientometrics approach from the perspective of quantity and impact index based on Scopus database data during the years 2010 to 2020?2. Literature ReviewThe review of the literature indicates that the quality of research outputs in Iran's major universities has been less studied over a long period of time and using multiple Scientometrics indicators. In most of the previous studies, only the average index and the percentage of documents were cited and the H index was used to study the quality level of research outputs. Therefore, according to the investigations carried out in the dimension of scientology and the need to pay attention to the quality of research outputs in addition to their quantity, the present article studies and analyzes the research outputs of major universities in Iran in the subject areas of social and behavioral sciences according to several indicators of effectiveness during the period of 2010-2020. In this way, it has helped to identify the scientific position of the universities in the subject areas of social and behavioral sciences, as well as planning for its development at the national level, and to help strengthen and improve the country's scientific rank at the international level.3. MethodologyThe current research is of an applied type and has been carried out with a Scientometrics approach and with documentary and citation analysis methods. The community under review is all research outputs in the subject areas of social and behavioral sciences, including "subject areas of psychology, economics (economics, econometrics and finance)", "management (business, management and accounting)", "social sciences", and "sciences", decision-making", according to the subject classification of the Scopus database, in the major universities of Iran in the years 2010 to 2020. The research implementation environment was Scopus and Scival databases. Research data was collected from March 20 to March 28, 2019 from Scopus and Scival. The method of data collection is to refer directly and get standard outputs from Scopus and Scival databases. The indicators used in this research are: citations, average citations per article, H index, weighted citation impact at the field level, percentage of highly cited articles, and percentage of articles published in top journals. Descriptive statistics (with Microsoft Excel software) were used to analyze the data.4. ResultsAccording to the results, the total number of research outputs in the subject areas of social and behavioral sciences of Iran's major universities in the target period was 19,582 records. In all the studied universities, the subject area of social sciences had the most research outputs. In general, the research outputs of Iran's major universities in the subject areas of social and behavioral sciences have been on the rise in the given period of time. The reason for this can be the increase of students and researchers in postgraduate studies. In terms of the number of citations index, Shahid Beheshti, Isfahan, Ferdowsi, Tabriz, and Shiraz universities have the most citations in the subject area of "social sciences" and in the universities of Tehran, Allameh Tabataba’i, and Tarbiat Modares, the subject area of "business, management and accounting" has the most citations. In most of the cases mentioned in the universities and subject areas under investigation that received the most citations, in terms of the index of highly cited articles at the threshold of 10% and the index of articles published in top journals at the threshold of 25%, they also took the highest percentages. This issue indicates the high quality of research outputs with more citations, which these findings are consistent with the vital and high research (2016) for this reason that the more the citations of the articles, the higher the quality. In terms of highly cited articles at the threshold of 10%, in the universities of Tehran, Tarbiat Modares, Isfahan, Ferdowsi, Tabriz, and Shiraz, the subject area of "Economics, Econometrics and Finance", and in Shahid Beheshti and Allameh Tabataba’i universities, the subject area of "Trade" "Management and accounting" got the highest percentages.5. DiscussionIn terms of the index of articles published in top journals at the threshold of 25%, in Shahid Beheshti, Tehran, Tarbiat Modares, Ferdowsi, Tabriz universities, in the subject area of "Business, Management and Accounting", in Allameh Tabataba’i University, in the subject area of "Psychology", in universities Isfahan and Shiraz have the highest percentages in the subject area of "Social Sciences". In this regard, it has been mentioned in most of the cases that they have obtained a high percentage in terms of the index of highly cited articles at the threshold of 10% and the index of articles published in the top journals at the threshold of 25%. This issue shows the high quality of research outputs in the mentioned subject areas, which with the research of Irfan Manesh and Hosseini (2016), in terms of the impact of general impact indicators (H index, weighted citation impact index at the field level, citations) on the increase of articles published in Top journals and highly cited articles match. Since some of the indicators examined in this research, such as citations and the number of highly cited articles, are included in some ranking systems, such as the rankings of Leiden University, Saimgo University, and Shanghai University, increasing the mentioned indicators as much as possible is effective in improving the position of universities in these ranking systems.6. ConclusionIn general, it is very important for universities to emphasize the quality of research outputs in addition to the quantity of these outputs. Attention to the quality of research outputs with the researches of Ebrahimi and Hayati (2007), Yaminifirouz et al. (2015) and Erfanmanesh and Hosseini (2018). Considering the number of received citations of the published research outputs of Iran's major universities in the review of their performance, as well as considering the special research credit and score for the authors of highly cited articles in various subject areas can be a suitable solution in this field. Also, emphasizing the quality along with the quantity of research outputs in universities and research centers should be given special attention.AcknowledgmentsWe are grateful to Shahid Beheshti University Research Vice-Chancellor for their support in the implementation of this research.

To evaluate demographics, academic backgrounds, and scholarly activities of Program Directors (PDs) in Abdominal Imaging Fellowships in the United States (US), emphasizing gender representation, international origins, and academic milestones. A list of Fellowships in Abdominal Imaging programs in the US was obtained from the Society of Abdominal Radiology. The search was expanded using the Fellowship and Residency Electronic Interactive Database. Data for PDs were sourced from program websites, Healthgrades, Doximity, and Elsevier's Scopus. Metrics such as age, gender, education, academic rank, additional qualifications, prior leadership roles, publications, and h-indices were analyzed using R software. A two-tailed unpaired t-test was used to calculate the difference in means of scholarly activity between male and female PDs. 113 programs were identified: South (36.28%), Northeast (25.66%), Mid-West (20.35%), West (17.69%). Of 107 PDs, 54% male, 41% female, and average age 48 ± 9.4 years. 66.6% were US graduates, 29.2% were international graduates. Most were Assistant Professors (36.28%). 19.46% had degrees like M.P.H. or M.B.A. 45% had prior leadership roles. Average year of residency graduation was 2007. Mean publication count was 54.16, and mean h-index was 14.663. Male PDs had higher publication counts and h-indices than female PDs (p= 0.009 and p= 0.0019 respectively). In Abdominal Imaging Fellowship programs in the US, there is an increasing representation of females in Program Director roles. However, research led by female PDs remains less prevalent. The field of Abdominal Imaging values contributions from international graduates and insights from Assistant Professors. [ABSTRACT FROM AUTHOR]

To describe an intuitive and useful method for measuring the global impact of a medical scholar's research ideas by examining cross-border citations (CBCs) of peer-reviewed neurosurgical publications. Publication and citation data for a random sample of the top 50 most academically productive neurosurgeons were obtained from Scopus Application Programming Interface. We characterized an author-level global impact index analogous to the widely used h -index, the h global -index, defined as the number of published peer-reviewed manuscripts with at least the same number of CBCs. To uncover socioeconomic insights, we explored the h global -index for high-, middle-, and low-income countries. The median (interquartile range) number of publications and CBCs were 144 (62–255) and 2704 (959–5325), respectively. The median (interquartile range) h -index and h global -index were 42 (23–61) and 32 (17–38), respectively. Compared with neurosurgeons in the random sample, the 3 global neurosurgeons had the highest h global -indices in low-income countries at 17, 13, and 9, despite below-average h -index scores of 33, 38, and 19, respectively. This intuitive update to the h -index uses CBCs to measure the global impact of scientific research. The h global -index may provide insight into global diffusion of medical ideas, which can be used for social science research, author self-assessment, and academic promotion. [ABSTRACT FROM AUTHOR]

This paper studies cultural and socioeconomic factors that contribute to the scientific output of different countries. Specifically, taking into account the influential Hofstede's model, we assess the impact of cultural dimensions on the h-index. Results show the h-index is connected to the Gross Domestic Product of each nation, the degree to which individuals are dependent upon one another, the total number of researchers, and the gender roles prevalent in a specific country. A classification of the examined countries was accomplished by factoring in the significant variables, determining the characteristics shared by each group in accordance with their h-index, and singling out the distinguished Group of Seven and the Scandinavia group as particularly noteworthy examples. This study provides valuable insights for governments and policymakers, emphasizing the significance of these cultural factors in guiding countries toward excellence in science.

A number of indices exist to help climatologists understand and communicate varying aspects of local to global scale conditions. The h‐index can be applied to weather data to summarize the magnitude and frequency of heat events on an annual or seasonal basis. Using both station and reanalysis model output data for the Arabian Peninsula, this research documents the value of the h‐index approach. The method is applied to daily high temperature, daily high apparent temperature, warm overnight low temperature and warm overnight apparent temperature for the period 1991–2022. Application of the h‐index approach to data from the Arabian Peninsula provides findings that strengthen and add to existing knowledge for the region. Findings from analysis of the ERA5‐Land dataset reinforce the findings from station data and provide results for wall‐to‐wall coverage of the study area, with lower h‐index values at higher elevations. Trend analysis results corroborate ideas related to greater warming of overnight lows. The findings document that the h‐index can be used in a subtropical desert climate region.

Introduction: With the passage of the Physician Payment Sunshine Act, there has been increased transparency regarding the industrial financial relations that physicians have. Orthopedic surgeons have been highly studied in this domain with approximately 50% of all orthopedic surgeons engaging in industrial financial relationships. Furthermore, an increasing number of orthopedic surgeons are seeking fellowship training with pediatric fellowship programs gaining popularity in recent years. The purpose of this study is to evaluate the impact various pediatric orthopedic fellowship programs have on industry earnings and academic productivity. Methods: Pediatric orthopedic fellowship programs were identified via the Orthopedic Society of North America (POSNA) website. Information on individual fellowship programs was obtained from their respective websites. Academic productivity was measured via an aggregate of all employed physicians' H-index at a specific fellowship as found on the Scopus website. The Open Payments Database (OPD) website was used to assess lifetime industry earnings. Other variables such as Newsweek or Doximity ranking were taken directly from relevant websites. Statistical analysis was performed using a Kruskal–Wallis test with Bonferroni correction and Mann–Whitney U-test. Results: A total of 43 pediatric orthopedic surgery fellowships in the United States were identified with a total of 392 physicians as fellowship faculty. Complete OPD and H-index information were available for 336 of those physicians (85.7%). On average, there were 7.81 ± 5.18 physicians and 1.56 ± 0.93 fellows per program. The mean combined physician H-index was 117.23 ± 122.51, and the mean combined physician lifetime supplemental earnings in dollars was $646,684.37 ± $1,159,507.17. There was no significant relationship between region of pediatric orthopedic fellowship, Newsweek ranking of affiliated hospital, Doximity ranking of affiliated hospital, presence of MBA program, type of program (public, private, mixed), and the lifetime industry earnings or academic productivity of program graduates. Conclusions: Despite the observed lack of statistical significance, there were clear trends observed with fellowship programs in the northeast and west coast regions being the highest earning and fellowship programs with top 10 Newsweek ranking of affiliated hospital having by far the greatest industry earnings. Sample size limitations likely prevented the detection of statistical significance. Future studies should examine if any relation exists when accounting for type of industry payment received and case volume per fellowship program. [ABSTRACT FROM AUTHOR]

h-indexes, Journal Impact Factors and CiteScores are often presented as a single numeric value, without providing any context. Under such circumstances, the reader is unable to fully appreciate, or comprehend, the information being presented. By not being transparent, it also presents the opportunity for unscrupulous operators, such as predatory journals, to provide non-sensical information in the hope that the potential author will misinterpret it and submit an article in the expectation that they are submitting to a high-quality journal. Dubious metrics are also able to enter the sector, again in the hope that their metric will be read under an incorrect assumption. Following an overview of the main metrics that are commonly used, this paper suggests how these metrics should be cited. Adopting these proposals would not only provide the reader will full information but also enable bogus measures, which have proliferated in recent years, to be recognized more easily.

Objective: To characterize Twitter utilization among academic otolaryngologists and evaluate the relationship between Twitter utilization and research productivity. Methods: Data were collected manually from accredited US otolaryngology residency programs from July–November 2021. Program and faculty demographics were documented, including citations and H‐index for faculty and Doximity reputation and US News and World Report ranking for programs. Twitter metrics were also recorded. Descriptive analyses and multivariable logistic regression models were used to identify predictors of Twitter utilization. Results: Currently, 333 (16%) faculty and 70 (62%) programs have a Twitter account. Of these, 36 (11%) and 27 (39%), respectively, were created in 2020. The regression model indicates that for each 5 unit increase in H‐index, the odds of having a Twitter account increase 22% (OR 1.22, 95% CI 1.10–1.34, p = 0.0009). The number of faculty with a Twitter account predicts the existence of program Twitter accounts (OR:1.49, 95% CI 1.01–2.19, p = 0.04). Finally, of the 323 faculty with a Twitter account and available Scopus profile, we found that the number of individuals with Twitter use out of proportion to their academic productivity was low (n = 8/323). Conclusion: The H‐index is a significant predictor of faculty Twitter accounts, whereas the number of faculty with Twitter is a significant predictor of program Twitter utilization. Although Twitter utilization is increasing, especially during the coronavirus pandemic, the findings indicate that there is ample room for growth, particularly amongst faculty with strong academic portfolios.

IntroductionThe h-index measures researchers’ productivity by assessing simultaneously the number of publications and citations. We aimed to assess the factors that could influence h-index for hematologists practicing in academic institutions in Canada.MethodsWe identified universities with a hematology residency training programs/fellowships using the Canadian Resident Matching Service (CaRMS) website. We obtained the listing of faculty, sex, and academic ranks by consulting faculty directories or by contacting respective departments/universities, when directories were unavailable or incomplete. For each faculty member, we obtained years since Royal College of Physicians’ and Surgeons of Canada certification or equivalent, receipt of Canadian Institute of Health Research (CIHR) grants within the last 5 years, attainment of graduate degrees (M.Sc., Ph.D., other), and the h-index.ResultsThe data included information collected from 372 individuals (171 females) across Canada (Atlantic Provinces: 13; Quebec: 89; Ontario: 182; Prairie Provinces: 59; British Columbia: 29). Univariate analysis showed that male sex, practicing in British Columbia, longer duration since specialty certification, completion of an M.Sc. or a Ph.D. degree, attaining a higher academic rank and receiving CIHR funding were associated with higher h-index. The results of the univariate analysis were concordant with the multivariate analysis, except that practicing in Ontario was also associated with higher h-index.ConclusionThis study provides details on the h-index curve/parameters for academic productivity of hematologists in Canada. Importantly, based on multivariate analysis, higher h-index was associated with male sex, location of practice, years since certification, attainment of M.Sc. or Ph.D. degrees, academic rank, and recent CIHR funding.

Background: Institutional academic productivity varies on an individual level. This study aims to analyze the research output of adult reconstruction and arthroplasty fellowship programs in the United States. Methods: The American Association of Hip and Knee Surgeons Fellowship Directory was used to evaluate 112 adult reconstruction and arthroplasty fellowships in the United States. Publication data and Hirsch index (h-index) were collected from the Scopus Database. All of each author’s total publications were analyzed with their current institution, regardless of their affiliation at the time of publication. Multivariate logistic regressions were performed to determine the effect of program size on research productivity. Results: The total number of publications per institution ranged from 2 to 3743, with a mean of 289 and a median of 135. The h-index of individual faculty members ranged from 0 to 103, with a mean of 16 and a median of 11. The number of faculty (P < .001) and number of fellows (P = .003) per program had a significant effect on the total number of publications. The number of faculty did not have a significant effect on the median number of publications (P = .12) or the median h-index (P = .31). The number of fellows had a significant effect on the median number of publications (P < .001) and the median h-index (P < .001). Conclusions: Academic productivity in adult reconstruction and arthroplasty fellowships within the United States varies widely, with the top few institutions responsible for a majority of the overall output.

Objective: To elucidate the current academic, demographic, and professional factors influencing the career trajectories of the American Association of Neurological Surgeons (AANS) William P. Van Wagenen (VW) fellows while also identifying trends that may influence future fellow selection. Methods: Fifty-five VW fellows were identified from 1968 to 2022 from the AANS website, along with corresponding institutions, countries, and continents of study. Additional variables such as age at selection, accruing additional degrees, neurosurgical subspecialty, the number of publications at the time of selection, funding, and h-index were collected from various publicly available sources. Results: Eighty-five percent of VW fellows were male and had a mean age of 34 ± 2.4 years. Ninety-one percent of fellows chose to study in Europe, and 40% had earned additional degrees. Univariate linear regression demonstrated a positive relationship between the year of selection and both age at selection (p = 0.0094) and the number of publications at hire (p

Abstract Professorships in Italy are assigned following public competitions. However, favouritism affects faculty hiring. Researchers lacking clientelistic support remain excluded from academia and are obliged to seek employment abroad or at non-university institutions, or to abandon their career. Do non-recruited researchers have better or worse scientific capacity than those who have attained professorships in Italy? Files regarding the competitions in bibliometric disciplines won by 186 professors in Florence were analysed. An equal number of professors recruited at other Italian universities and scientists who never attained professorship in Italy were randomly drawn from the pool of individuals having national scientific qualification (the prerequisite for professorship) in the same disciplines as each Florentine professor. H-indexes of the year of qualification (T1), of the Florence call (T2), and in July 2021 (T3) were obtained from Scopus. Non-recruited individuals were more likely (Chi-square test) to show a higher H-index than both Florentine (T1 p = 0.0005, T2 p = 0.0015, T3 p = 0.0095) and non-Florentine professors (T1 p = 0.0078, T2 p = 0.0245, T3 p = 0.0500). Fifty-four non-recruited scientists serve in foreign universities, 100 at national/international research centres. The remaining scientists (25 who continue producing despite precarious employment, and seven who have stopped publishing) were as likely as Florentine (T3 p = 0.69) and non-Florentine (T3 p = 0.14) professors to show a higher H-index. Italian faculty hiring disregards merit. A more challenging qualification would limit the access of researchers with lower scientific capacity, and favour those with greater proficiency. As it stands, competition is useless. Once professors obtain permanent employment, they seem less motivated to publish.

Background and purpose: Current scientometric indicators have some strengths and weaknesses. This study was conducted with the aim of developing a new scientometric index for the comprehensive scientific evaluation of researchers, the so-called multifold index. Materials and methods: The study was conducted with 96 researchers from Mazandaran University of Medical Sciences with at least two articles in Scopus and at least one citation to the articles. A checklist was used that included variables, such as the scientific age of each individual, the square root of the total number of each article, the sum of references to top articles, the H-index, etc. Some statistical analyzes such as factor analysis, KMO test and Bartlett’s test for sphericity, correlation matrix and SPSS software version 22 were used. Test functional characteristics and area under the rock curve were used, and sensitization was performed, extracting 99% predictive power and diagnostic power (0.7). Results: When calculating the multifold index, the H-index has the largest weight of 0.238, and the numerical value it provides is appropriate and measures all aspects of a person's scientific activity. This index is different for researchers who have the same H-index. Conclusion: The Multifold Index leads to a qualitative assessment and takes into account all aspects of a person's scientific activity. It can be used for assessments, predictions about the scientific status of researchers, educational and research groups and for creating a comprehensive scientific map of the country.

Purpose: In academic publishing, research metrics play a crucial role in assessing the scientific impact and performance of the published literature, as well as of the journals in which they are published. Several journal-level metrics (JLM) such as the h-index of the analysed journals, total citations, total documents, citable documents, references and external citations per document are considered crucial indicators of the importance and reputation of the journals. We hypothesize that journals in the field of Medicine receive more citations than those in Surgical journals like Orthopaedic surgery, and hence have better JLM. This study aims to to assess and compare the JLM of Medical and Surgical journals between two time zones 2017–2019 vs. 2020–2022, i.e., pre and post-COVID-19 pandemic period. Methods: A cross-sectional bibliometric analysis of the top-ranked Orthopaedic, Medical, and Surgical journals was undertaken based on traditional JLM, using the SCImago database from 2017 to 2022. Our analysis focused on identifying trends in the h-index of the analysed journals, total citations, total documents, citable documents, references and external citations per document. Results: Overall Medical journals were found to have higher JLM than the Surgical and Orthopaedic journals. The h-index of Surgical journals, Medical journals and Orthopaedic journals were comparable between the two periods (pre and -post-COVID-19 pandemic); Total Cites (3 years), total documents (2017), total documents (3 years), total references, and citable documents (3 years) of Surgical journals, Medical journals and Orthopaedic journals were significantly higher in the period 2020–2022. Conclusion: There has been a steady increase in the number of publications from post COVID-19 period. Medical journals have higher JLM than Surgical and Orthopaedic journals. Journal of Bone and Joint Surgery (Am), Annals of Surgery and Diabetes Care were the most published journals in Orthopaedics, General Surgery and Medicine-related topics respectively.

An H -sequence of a vertex is defined by iteratively applying H -index to neighbors of the vertex in a graph. It is still not known whether changing the initial values affects the convergence of H -sequences. Our purpose is to investigate the properties of H -sequences initialized with arbitrary positive integers. This paper presents the necessary and sufficient conditions for the convergence of H -sequences. Theoretical results reveal the differences between divergent H -sequences of infinite graphs and finite graphs. Divergent H -sequences of infinite graphs are either periodic or non-periodic, whereas divergent H -sequences of finite graphs must be periodic with a period of 2. Based on H -sequences, we define 2-step coreness on the second-order neighbors of a vertex. A new centrality is proposed by combining classical coreness and 2-step coreness. The new centrality captures a wider range of information in a network. Experimental results show that the proposed centrality makes significant improvements over centralities such as betweenness, H -index and coreness. [ABSTRACT FROM AUTHOR]

A major critique of the h-index is that it may be inflated by noncritical authorship. We propose a modified h-index (h m), incorporating critical authorship, complementary to the h-index. We analyze its relationship to the traditional h-index, and how each varies across professional categories relevant to academic neurosurgery. This analysis is not meant to critique authorship decisions, affect career development, alter academic legacy, or imply that the concepts of team science or midlevel authorship contributions are not valuable. H-indices and h m s were gathered and computed for clinical neurosurgical faculty at the top 32 ranked academic neurosurgical programs based on the current literature. H m was computed for faculty at each program, using articles in which the individual was first, second, last, or co-corresponding author. Individuals were further identified based on chair status, leadership status, neurosurgical subspecialty, and National Institutes of Health funding status. Further analysis was performed to determine factors influencing h-index and h m. The median h-index for the 225 physicians included in the final dataset is 48 (interquartile range [IQR], 39−61), whereas the median h m was 32 (IQR, 24–43). The median difference between h-index and h m is 15 (IQR, 10−23). The median h m /h was 64% (IQR, 57–74). National Institutes of Health funding and subspecialty (neurosurgical oncology, neurocritical care, and cerebrovascular) were associated with significant change from h to h m. The h-index can be influenced by noncritical authorship, and h m , using critical contributions, can be used as a complement reflecting critical academic output in neurosurgery. Leaders deciding on hiring or promotion should consider disparities in productivity predicated on noncritical authorship contributions. [ABSTRACT FROM AUTHOR]

The two aims of this study were to: 1) identify the 100 most impactful contributors to English-language gerontological journals, and 2) map their respective disciplinary affiliations to help illuminate the perspectives shaping gerontological discourse. Toward that end, we conducted a secondary data analysis of a publicly available database of the world's leading scientists. After extracting all scientists in the gerontological category, we rank ordered them according to a composite measure of scholarly impact that controls for self-citations and author order while also calculating other bibliometric statistics. Disciplinary affiliations were assigned based upon the Classification of Instructional Programs codes developed by the National Center for Education Statistics at the United States Department of Education. The results reveal the mean contributor to the gerontological literature published 241.15 (SD = 203.95) papers and – after correcting for self-citations – had an h-index of 50.05 (SD = 25.00), and an hm-index 23.67 (SD = 7.50). A diverse array of professional affiliations characterized the contributors with a plurality being located in the health professions category, followed by the biological and biomedical science, and social sciences categories. The results reveal that gerontology is home to some of the world's leading scientists. Leveraging their expertise can help advance the field's collective knowledge development.

The h-index has become more popular nowadays and is used for some scientific performance criteria worldwide. This indexing method does not correctly measure any performance or career specifications because of the parameters used to form the measurement basis. The h-index is located based on citation(C) and paper(N) parameters that involve no logical criterion on the counting process, and so measurement on this basis can only give quantity results not any quality information. Therefore, we need a new indexing instrument to find out also the scientific quality unique to an individual author even if that takes into account the effect of multiple coauthorships. Ipso facto, we create a new bibliometric indicator or academic performance indicator called the u-index. [ABSTRACT FROM AUTHOR]

University rankings, despite facing criticism, continue to maintain their popularity. In the 2023 Scopus Ranking of Ukrainian Universities, certain institutions stood out due to their high h-index, despite modest publication and citation numbers. This phenomenon can be attributed to influential research topics or involvement in international collaborative research. However, these results may also be due to the authors' own efforts to increase the number of citations of their publications in order to improve their h-index. To investigate this, the publications from the top 30 universities in the ranking were analysed, revealing humpback rank-citation curves for two universities. These humpbacks indicate unusual trends in the citation data, especially considering the high percentage of self-citations and FWCI of analysed papers. While quantitative analysis has limitations, the combination of humped rank-citation curves, self-citations, FWCI, and previous research findings raises concerns about the possible causes of these anomalies in the citation data of the analysed universities. The method presented in this paper can aid ranking compilers and citation databases managers in identifying potential instances of citation data anomalies, emphasizing the importance of expert assessment for accurate conclusions.

Robust findings of citations have a positive impact on researchers and significantly contribute to academic development. As a paper is cited more frequently or used as a reference in other articles, its citation count increases. Papers with higher citations tend to be more influential than those less cited. Research on predicting citation counts has evolved throughout the year in various fields. However, despite its recent growth, research on identifying commonly used features and techniques still lacks a comprehensive literature analysis. The present study addresses this gap and identifies frequently used features and existing techniques and their evaluation process for predicting an article's citations. This study reviewed 150 articles from 2010 to 2023, and selected 107 based on established exclusion and inclusion criteria. It provides an overview of publication features and the standard techniques used for their identification to facilitate improvements in this field. The findings indicate that previous works frequently used (i) selected features such as paper features and citation features in predicting citations and (ii) machine learning techniques that are commonly applied to predict article citations. These findings can provide beneficial information for researchers aiming to enhance their papers and maximize their impact. [ABSTRACT FROM AUTHOR]
