Objective: Assess the accuracy of abstracts in published veterinary ophthalmology articles. Procedures: Abstracts and contents of 204 original research articles in veterinary ophthalmology published in seven peer‐reviewed journals between 2016–2020 were reviewed. Abstracts were considered inconsistent if they contained data that were either missing from or inconsistent with corresponding data in the article's body. Each abstract was graded between 0 (inaccurate) to 3 (accurate), and each inconsistency was subjectively classified as minor or major. The influence of selected variables was assessed: journal, impact factor, year of publication, number of words in abstract, study type (prospective/retrospective), and characteristics of the corresponding author [institution (academia/private practice), country of domicile (native/non‐native English), number of publications]. Results: Most abstracts were accurate, with 1%, 4%, 9% and 86% receiving a score of 0, 1, 2 and 3, respectively. When detected, most inconsistencies were considered minor (77%). Although not statistically significant (p ≥.130), the proportion of articles with a perfect score (=3) was higher in prospective (88%) vs. retrospective (81%) studies, academia (88%) vs. private practice (78%), and studies from corresponding authors domiciled in English (89%) vs. non‐English (83%) speaking countries. A significant but very weak (r = −0.15 to −0.19; p ≤.034) negative correlation was found between accuracy score and number of words, as well as 1‐year and 5‐year impact factors. Conclusions: Although relatively uncommon, data in abstracts that are inconsistent or missing from the article's body do occur in veterinary ophthalmology articles, and could adversely influence a reader's interpretation of study findings.

Late Paleozoic strata in the southeastern Ordos Basin comprise targeted reservoirs for tight gas exploration. As a typical intracratonic basin, the Ordos Basin is characterized by low-accommodation space and a complex sediment infilling process, which attracts much attention. During the early Permian, the southeast area was fed by sediments from multiple sediment sources, which makes it difficult to identify the pinch-out of the sand bodies and reconstruct the sediment routing system. In this study, we reconstruct the paleo-topography of the late Paleozoic setting using high-resolution 2D and 3D seismic data. Thus, we identify two types of topography: the eastern block is presented as a semiclosed depression, and the western block is observed as a flat platform. Based on detrital zircon U–Pb data and heavy mineral assemblages, we reconstruct the provenance area and show that early Permian sediments originate from the northern margin of the Ordos Basin and from the northern Qinling orogenic belt in the south. By integrating the trace element contents, carbon and oxygen isotope data and sedimentary structure from core samples, we can observe the paleoenvironment and the corresponding facies associations in these blocks. The eastern block was infilled by a prograding delta; the western block was infilled by a tide-dominated delta or a wavy-dominated delta. By using stratigraphic forward modelling, we find that most sediments in the semiclosed setting are progradational and intensely interacted. In contrast, the sediments in the western block present an open setting, infilled and gently interacted. The fine-grained deposits were not easily preserved due to tidal or wave reworking processes in the shallow-water marine setting, and they were transported into deep-water areas. Furthermore, to explore the dominant factors in a pattern of fluvial–deltaic sand bodies formed in the low-accommodation basin, we rebuild the sediment routing system parameters and plot them on a bubble chart. According to the fitness between the depositional volume and the above parameters, we determine the key factors in the routing systems that formed. The results show that the sediment supply has a high relevance to the depositional volume in a semiclosed setting, such as the eastern block, while the terrain height may drive sedimentation in an open marine setting, such as the western block. We demonstrate that two different infill patterns and different sand-body stacking patterns with multiple sediment sources in a low-accommodation basin may serve as a model for similar settings.

The impact factor (IF) assessment of a four-span non-prismatic continuous and an equivalent integral railway bridge under the action of high-speed moving train loads is conducted in this study. Critical analysis of the fullscale three-dimensional finite element (FE) bridge models is done to investigate the differences in the IFs of all the spans of the two-track railway bridge under various loading conditions. A simplified approach is proposed to identify the dynamic IF values. The results show that for a continuous bridge, with the increase in the load on the bridge, IF coefficients reduce from 0.195 to 0.102. However, for the integral bridge, and considered loading conditions, almost similar IF coefficients (0.100) are obtained. For the intermediate spans, the resonance phenomenon for the integral bridge is achieved at lower speeds compared to the equivalent continuous bridge. [ABSTRACT FROM AUTHOR]

ObjectivesReview abstracts presented at the Combined Otolaryngology Society Meeting (COSM) to determine subsequent publication and identify abstract features predictive of publication in high impact journals.MethodsA selection of abstracts accepted in the 2015 COSM scientific programs were retrospectively reviewed. MEDLINE searches via PubMed and Google Scholar were performed to determine publication rates. The Journal of Citation Reports was used to determine impact factors for published abstracts. Binomial regression analyses were used to identify factors related to publication in high impact journals.Results62.4% of reviewed abstracts (n = 623) were subsequently published, with a mean publication time of 14 ± 12 months. Abstract features predictive of publication were basic science type, other science type, prospective studies, multi-institutional involvement, and presentation at the American Laryngologic Association and American Otologic Society meetings. Based on Wald score, podium presentation was found to have the biggest effect on publication. Factors positively associated with publication in high impact (impact factor > 2.272) journals were increased author number and sample size.ConclusionsOverall publication rate of abstracts selected for presentation at COSM in 2015 was on the higher end of previously reported otolaryngology meetings. Abstracts detailing basic science, other science, prospective and multi-institutional studies were more likely to lead to future publication. Additionally, increased number of authors and sample size lead to publication in higher impact journals.Level of evidenceN/A.

Abstract Objective This study aims to identify determinants of high impact, measured by Impact Factor (IF) and Eigenfactor score, among otolaryngology journals. Methods Bibliometric data of “otorhinolaryngology” journals were collected from the Journal Citation Reports (JCR) database. For the years 2009–2020, we collected normalized Eigenfactor score, 5‐year IF, immediacy index, fraction of IF from journal‐self citation, proportion and magnitude of published citable articles, and total citation counts. High‐IF and ‐Eigenfactor journals were considered those within the top‐quartile of that metric each respective year. Results High‐IF and ‐Eigenfactor otolaryngology journals displayed higher 5‐year IFs, immediacy indexes, and IF without self‐citation (p .05 for 2009‐2016). Eigenfactor correlated with 5‐year IF, total citation counts, and citable articles within the same year (p .05 for 2009‐2016) predicted 2019 IF. Similarly, 5‐year IF, total citation counts, and citable articles (p

Background: In recent years, conventional thoracoscopic surgery has been accepted as the traditional treatment method in the non-small cell lung cancer (NSCLC). VATS and RATS, which are the techniques of this surgical method, have been increasing their effectiveness and applicability of late years. The aim of this bibliometric analysis is to evaluate the importance and efficiency of articles comparing VATS and RATS techniques. Materials and methods: Studies comparing VATS and RATS published between 1997 and 2021 were identified in the Web of Science database (accessed on 31. 12. 2021). The 40 most cited studies were analyzed in terms of publication years, country of study, authors, institutions that the authors were affiliated with, journal, journal address and impact factor. Results: While an article was cited a maximum of 187 times when the citations made by the authors were excluded from the analysis, it was observed that all publications were cited a total of 1946 times. It was seen that an average of 51. 30 ± 47. 73 (8–187) articles were cited. In the 25-year, the highest number of publications was reached in 2019, while eight articles were published this year. The Annals of Thoracic Surgery (n = 13, 32. 5 %) was the journal in which the articles in the list were published the most. Most of the articles in our study (n = 31, 77.5 %) were published in US journals. While many studies presented more than one topic and analysis, the topic of most interest in 19 (47.5 %) studies was postoperative complications. Conclusion: This bibliometric analysis reflects important and qualified articles comparing VATS and RATS technique in thoracic surgery, but it can also be used to explain or explain the performance and results of these techniques, their positive and negative aspects, and their superiority over each other.

As the COVID-19 pandemic became a global health concern, many business activities have had to adjust to the protocols required to keep people safe, thereby altering the work structures of many professionals. With data gathered from 466 respondents in Nigeria, of which approximately 70% are from the South-West, this study shows how the factors associated with the health crisis have affected work productivity during this period. The snowball survey research design techniques with the two-way interaction model were employed. Multiple Correspondence Analysis was used to analyse and understand multiple and pairwise qualitative factors that influence productivity. The first part of the analysis identified boredom, remuneration, internet availability, fear of COVID-19 and depressing news of COVID-19 as the factors that had significant impacts on workers’ productivity. The second part of the analysis shows how the categories of the five significant factors were either associated or not with productivity. An analysis of each of these factors showed that fear of the disease was associated with slight productivity but access to internet facilities and remuneration were strongly associated with improved work productivity, while boredom and depressing news about COVID-19 were associated with non-productivity during this period. Further evidence also showed that training and new skills acquisition might improve workers’ productivity much more. We, therefore, recommend dynamic skills acquisition, training, and investment in tools and services that will enhance flexibility with the changing work structure that comes because of global crises.

In order to improve the bearing capacity of a bridge under dynamic impact and at the same time to improve the durability and safety of the bridge, the bridge should be jacked up, and most of the current research on bridge jacking upgrading is on synchronous jacking upgrading. There has been little research on single-pier jacking upgrading, especially the dynamics response problem under single-pier jacking upgrading of the bridge. This paper is based on the principle of vehicle–bridge coupling, and the vehicle was analyzed at different speeds by using the established model, vehicle weight, and multi-lane driving, comparing the dynamic response of the bridge before and after the single-pier jacking retrofit. The study analyzed the impact of the bridge single-pier jacking retrofit on the bridge impact coefficient, and evaluated the impact coefficient of the bridge from the perspective of dynamics. A comprehensive evaluation of the bridge single-pier jacking retrofit project was carried out. The following conclusions are drawn: the single-pier jacking modification of the bridge increased the bridge's capacity under dynamic impact and also enhanced the durability and safety of the bridge.

Purpose: To examine a series of papers from top ranked orthopaedic journals with respect to the number of citations over a 10-year observation period to identify factors that lead to high citation rates. Methods: The Web of Science database was consulted to identify all published papers from the first-year term of 2010 (January-May) from four top orthopaedic journals: AJSM, Arthroscopy, JBJS Am and KSSTA. The database was used to analyze and compare the papers with respect to their characteristics and citations up to 2019. Basic information for each paper was collected including the author, country, study type and average citations per year (ACY). The most (Top20%) and least (Bottom20%) frequently cited papers were identified and differences were extracted. Results: Five hundred sixteen papers were included with a total of 19,261 citations. Most of the published papers were from the United States (n = 245). On average, a paper received 37.3 citations over the 10-year observation period. The most cited paper was cited 322 times. The most cited study type was randomized controlled trial (RCT) (Ø80.8). The Top20% papers were cited 37 times more often than the Bottom20%. Among the Top20%, the largest group was cohort study (n = 20) followed by case series (n = 19). Among others, the number of authors, the number of keywords and the number of references significantly correlated with the number of citations (p < 0.001). Conclusions: Factors influencing citation frequency were identified. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this study was to bibliometrically analyze the 100 most‐cited articles published in the Veterinary Ophthalmology (VO) journal. Methods: Web of Science was searched for citations of VO articles published in 1998–2022. Tissue and species studied, and first and last author domicile and affiliation were recorded for the 100 most‐cited articles and descriptively analyzed. Results: Altogether, the 100 most‐cited VO articles have cited a total of 5483 times. Most commonly, these were devoted to the cornea (23%), multiple tissues (19%), and glaucoma (16%). Studies on dogs (36%), horses (17%), and multiple species (15%) were most often cited. Most first/last authors were from the USA (n = 113), Brazil (n = 13), and France and Germany (n = 7 each), and most frequently affiliated with the University of Florida (n = 36), University of Wisconsin‐Madison (n = 15), and Animal Health Trust, North Carolina State University, and Ohio State University (n = 6 each). KN Gelatt (n = 9), DE Brooks (n = 6), and FJ Ollivier and EO MacKay (n = 5 each) were the most frequent first or last authors. The greatest number of citations was for articles with KN Gelatt (n = 555), FJ Ollivier (n = 411), and DE Brooks (n = 372) as first or last authors. "The comparative morphology of the tapetum lucidum" by FJ Ollivier et al. (2002) is the most frequently cited article in VO history (n = 178). Conclusions: This study provides insight into the impact of publishing in VO and a more comprehensive understanding of trends and the most influential contributions to VO. [ABSTRACT FROM AUTHOR]

Scholar performance evaluation plays a key role in management science and engineering. Scholar evaluation using Google Scholar and ResearchGate can serve as an indispensable scouter for evaluating scholar performance. Both tools to quantitatively evaluate scholars can be used to support evidence-based decision making in administration and human resources. However, both tools must be used together for complementing accurate scholar evaluation. This author shows examples of fatal drawbacks in Google Scholar and ResearchGate, respectively. Scopus and Publons, used as default scholar performance, are affected by publisher-bias selection of journals and conferences. The author recommends scholar performance evaluation using both tools such as Google Scholar and ResearchGate together with Scopus and Publons. [ABSTRACT FROM AUTHOR]

Rail-structure interaction (RSI) analysis and vehicle-track-structure-interaction (VTSI) analysis are often required during bridge design. For example, the California High-Speed Train Project requires RSI analysis for final design of all structures, as well as VTSI analysis, with the level of interaction to be modeled determined by the complexity of a structure. The goal of RSI analysis is to ensure that superstructure deformations and rail stresses are within acceptable limits. VTSI analysis is a dynamic analysis that takes into account influence of actual trainsets. VTSI Level 1 analysis includes train loads as a series of moving loads. This analysis allows evaluation of dynamic impact effects from trainsets and vertical accelerations of the deck. For complex high-speed railway bridges, VTSI Level 2 might be required, accounting for full dynamic interaction between the trainset and the bridge. To represent this interaction, the trainset is modeled as a multibody system consisting of rigid bodies, springs, and dashpots. The interaction between wheels and rails is accounted for through kinematic constraints and Lagrange multipliers. This paper presents modeling, RSI, and VTSI analyses of a railway bridge in the LARSA 4D software package. The track and superstructure are modeled in an expedited way using a macro that generates the track, approach, and bridge geometries. Fasteners are modeled as hysteretic springs and automatically positioned along the curved geometry of the track using a LARSA 4D's bridge path coordinate system definition. RSI analysis is performed accounting for temperature differentials between rails and the deck, vertical train loads, acceleration and braking forces. Break in the rail is introduced using stage construction analysis, followed by progressive collapse analysis (with adapting increments and arc-length control) or nonlinear dynamic analysis. Finally, VTSI Level 1 and 2 analyses are performed and the results are compared. Car body accelerations are compared to limit values to ensure passenger comfort. [ABSTRACT FROM AUTHOR]

Authors have a multitude of options for journals for publishing their research. However, their choice is mostly based on academic credits required for promotion, cost of publication, timeliness of process, etc., The purpose of this narrative review is to enlighten the authors about some other journal metrics used to assess journal ranking and quality in international scenario. The main concepts discussed in this paper are the impact factor and cite score. The paper includes an explanation of terms like web of science, journal citation reports, and how they are related to impact factor. This will help the authors to make the right decision about choosing the right journal for publishing their research. Along with the historic concepts we have included the latest updates about changes being made to the journal citation report and impact factor released in 2023 June. Hopefully with the review paper, we will be able to encourage the inclusion of such concepts and curriculum of post-graduation courses considering publishing a paper and choosing a journal are an integral aspect of a researcher's work life.

Background: Twitter is a social media platform popularly used by health practitioners, a trend that has been followed by medical journals. The impact of Twitter in bibliometrics of stroke-related literature is yet to be determined. Aims: We aimed to qualitatively assess the usage of Twitter by stroke journals and study the relationship between Twitter activity and citation rates of stroke articles. Methods: We used Journal Citation Reports to identify stroke journals. We collected the 2021 Impact Factor (IF) and the top 50 articles contributing to each journal IF. Relevant metrics were collected through Twitonomy, Altmetric, and Web of Science. The association between Twitter activity and citation rates was tested by a negative binomial regression model adjusted to journal's IF. A bivariate correlation and a log-linear regression model adjusted to journal's IF tested the relationship between number of tweets, tweeters, and the number of citations. Results: We collected 450 articles across nine stroke-dedicated journals, five of which had a Twitter account. Only 95 (21%) articles had no Twitter mentions. The median number of citations in articles with versus without Twitter activity was 19 (10–39) versus 11(7–17) (P < 0.001). Twitter activity was associated with higher citation rates controlling for the IF (odds ratio (OR): 2.7, 95% confidence interval (CI) 2.12–3.38, P < 0.001). We found number of tweets to be predicted by the number of citations controlling for the IF (B = 0.33, 95% CI 0.29–0.40, β = 0.54, P < 0.001). Conclusions: Tweeted stroke articles tend to have higher citation rates which can be predicted by the number of tweets. [ABSTRACT FROM AUTHOR]

This paper proposed a comprehensive model to examine (resource-based) factors affecting management and technological innovation, and in turn the impacts of management and technological innovation on organisational performance in auditing service sector. The results confirmed the significant impacts of all proposed factors on management and technological innovation directly or indirectly. Among proposed factors, internal source involvement showed its direct impact and its mediating effect as well. The results also attested the positive impacts of management and technological innovation on audit firm performance. Contextual factors (organisational size and age) were identified to have significant influences on organisational performance. In addition, organisational age showed its moderating role on the relationship between management innovation and operational performance. The moderating effects indicated that management innovation caused higher impact on younger audit firms. [ABSTRACT FROM AUTHOR]

Background: Journal impact factor (JIF) is a bibliometric proxy of relative journal importance. Mean dermatology JIF has nearly doubled since 1997. The reasons behind the increase have not been previously explored. Objective: To assess factors contributing to rising dermatology JIF. Methods: This bibliometric study utilized publicly-available citation and JIF data from the Thomson-Reuters InCites Journal Citation Reports "Dermatology and Venereology" category, from 1997-2017. Results: From 1997-2017, aggregate dermatology JIF increased by 70%, associated with a 64% increase in JIF numerator (total journal citations) and a 3% decrease in JIF denominator (total journal articles and reviews). In the four highest-JIF journals (JAAD, JAMA Dermatology/Archives of Dermatology, JID, and BJD), there was an increase in citations coming from non-dermatology specialty journals, including oncology, rheumatology, and multidisciplinary sciences. Journal impact factor was positively correlated with five JIF alternatives. Immediacy Index, a reflection of how fast dermatology journals are cited, increased four-fold (P

The use of bibliometric indicators, and in particular of the Impact Factor of journals in evaluating the scientific production of researchers, has recently been subjected to international review, highlighting the need to reconsider the peer-review activity as a procedure that allows to recognize the different activities connected to the research of scholars. The article discusses some reports published internationally – DORA, The Leiden Manifesto, Report of the European Commission of 2021 – and highlights the significant connection between good evaluation practices and the Hong Kong Manifesto, dedicated to research integrity and the ethics of research evaluation.

ObjectiveTo study the status and influencing factors of readmission in depression patients. MethodsFrom Chengdu Municipal Medical Insurance Administration, Sichuan province, we collected 25 043 medical and reimbursement records for 16 556 depression patients having hospitalizations during the period from 2013 through 2017; the hospitalization status of the patients was analyzed. Rank-sum test and Chi-square test were used in analysis on hospitalization-related difference among subgroups of the patients; logistic regression model was used to analyze influencing factors of some patients′ readmission. ResultsThe person-times of depression patient's hospitalization for 10 000 population increased from 1.92 in 2013 to 5.35 in 2017 and the person-times was higher for female population than for male population. Among all depression patients studied, the number of readmission within 30 days of discharge was 1 519 and 30-day readmission rate was 9.17%; the total number of readmission during the 5-year period was 3 854 and the 5-year readmission rate was 23.28%. The readmission rate was lower in the patients with medical insurance for urban and rural residents than that in the patients with medical insurance for urban workers. For all the re-hospitalizations recorded, the top three diagnosis at the readmission were mental and behavioural disorders (coded with F00-F99 in International Classification of Diseases and Related Health Problems, Tenth Revision [ICD-10], accounting for 28.35% of total re-hospitalization), circulatory diseases (I00-I99, 20.17%), and respiratory diseases (J00-J99, 16.27%), respectively. Logistic regression analysis showed that female gender, aged ≥20 years, covered by medical insurance for urban workers, having the hospital stay of ≥ 8 days, and being diagnosed as recurrent depression (ICD-10 code: F33) were significant risk factors for re-hospitalization of depression patients; while, having comorbidity disease and being hospitalized in primary/secondary/tertiary hospital were significant protective factors against readmission. ConclusionThe ratio of readmission was high among depression patients ever being hospitalized in Chengdu city and the re-hospitalization is mainly influenced by gender, age, medical insurance type, length of stay, depression type, comorbidity, and the grade of hospital providing hospitalization.

Over the decades, epistemologists and theorists of tourism have devoted considerable efforts in laying the foundations towards the discipline maturation. This so-called maturation would take the lead when tourism situated not only as a solid object of study but also professional publications reach a the scientific rigorism. The number of publications in the tourism fields has certainly been triplicated in the recent years, but today tourism has many barriers to become in a consolidated option. This happens because of many reasons. One of them associated to the problem of impact factor, the invention of academic prestige and the bibliometric studies. We, in this short note of research, explore the impossibilities, limitations and problems of the current tourism research which remains culturally embraced to impact factor logic. To put things in bluntly, the current obsession for impact factor in the academy is gradually leading the discipline into an unparalleled crisis.

The impact factor of scientific journals and the h-index depend on the citations. Therefore, the citation analysis is a very important part of scientometrics. The paper presents the 2022 ranking list of citation analysis researchers. The ranking is presented primarily according to the h-index of researchers. The advantage the h-index is that it combines both the quantity - number of articles and quality - citations to these articles. A researcher cannot have a high h-index without publishing a considerable number of articles. The h-index favors researchers that publish a continuous stream of articles. Researchers with the same h-index are ranked by the number of citations. The minimum h-index of the 10 ranked researchers is 26. h-index can be determined from the following online databases: Web of Science, Scopus, Google Scholar and the Publish or Perish program. The ranking is edited using the Google Scholar database.

Karst peak cluster depression areas are characterized by a special double-layer hydrogeological structure, and under the influence of human activities, there are many environmental problems, such as soil erosion, rocky desertification, dryness and wetness, and heavy metal pollution. How to clarify the spatial variations and influencing factor analysis of heavy metals in the soil of typical rocky desertification peak cluster depressions has become an important content to promote the prevention and control of heavy metal pollution in soil and the comprehensive management of rocky desertification. The typical rocky desertification peak cluster depression soil in Pingguo City, Guangxi, was selected as the research object in this study.Spatial variations, associated mechanisms and pollution risk assessments of eight heavy metals (e.g., As, Hg, Cr, Ni, Cu, Zn, Cd, and Pb) in soil were carried out by using the geo-statistical, geological accumulation index, potential ecological danger index and geographical detector methods. These results show that the spatial distribution of heavy metals in the study area generally shows a downward trend from northeast to southwest. Cr and Cd show medium spatial correlation, and the other six heavy metals show strong spatial correlation, which was analyzed by semivariogram. The study area is affected by different pollution levels of Cd, As, Cr, Cu and Zn, and the impact of Cd is the most important. The geological accumulation index and potential ecological hazard index of Cd are 1.34 and 107.73, respectively, but the average geological accumulation index of other heavy metals is less than 0, and the potential ecological hazard index is less than 16.The main factors affecting the spatial differentiation of eight heavy metals in the soil of the study area are pH, stratum, Fe2O3, land use, phosphorus, CaO, Mn, distance to fault and rocky desertification degree. Moreover, the interaction types of different factor groups on the spatial differentiation of heavy metals in soil were mainly two factors enhanced and nonlinear enhanced. Therefore, it is considered that different factors have different effects on the spatial differentiation characteristics of various heavy metals in the soil of rocky desertification peak cluster depression. Cd is the most serious heavy metal element in the soil pollution degree and potential ecological harm degree of rocky desertification peak cluster depression. Strata, Mn, CaO, lithology, distance to fault and phosphorus are the key factors affecting the spatial differentiation of Cd.

However, Japanese academic generalists’ contribution to research remains unclear. This study examines the popularity of Japanese general medicine research, the characteristics of journal publications, annual trends, and the characteristics/differences among publications in journals with an impact factor (IF).Methods: This bibliometric analysis extracted international, English-language, journal articles published on PubMed between January 1, 2015, and December 31, 2020. Analysis included articles with either the first, second, or last author in general medicine. We classified articles according to publication or article type and field of research. We obtained standard descriptive statistics for each publication type. Chi-squared test or Fisher’s exact test was used to compare nominal variables. For continuous variables, t-tests or Wilcoxon rank-sum tests were used, as appropriate.Results: Of the 2372 articles analyzed, original articles were most common (56.3%), followed by case reports (30.1%), reviews (7.63%), and letters/others (5.9%). Publication volume increased 2.64-fold annually over 5 years. Clinical research (60.5%) was most common among original articles, followed by basic experimental research (17.5%) and public health/epidemiology (12.7%). Medical quality and safety (4.1%), medical and clinical education (3.1%), and health services (1.42%) received comparatively little attention. Eighty percent of articles were published in journals with IF; however, these journals rarely published case reports. Among original articles, the likelihood of publishing in journals with IF was high for basic laboratory medicine articles with higher IF (median IF 3.83, OR 1.71, 95% CI 2.20– 5.95, p=0.044) and lower for clinical education research with the lowest IF (median IF 1.83, OR 0.56, 95% CI 01.8– 0.75, p< 0.001).Discussion: General medicine physicians’ international research output is increasing in Japan; however, research achievements have not been generalized, but rather much influenced by clinical subspecialty backgrounds. This will likely continue unless an academic generalist discipline is established.Keywords: general medicine, academic generalist, research productivity, research trend, impact factor

The social organization of the Russian scientific community is such that many established ethical standards conflict with the real research practice. Using exclusively scientometric approaches to assessing scientific achievements leads to the fact that the quantitative indicators of this assessment prevail over the true results of research activity. The paper aims to reveal organizational problems associated with the interaction with junk journals that result in ‘clogging’ and ‘emptying’ objective scientific knowledge about the modern world. The theoretical basis of the study includes scientometric approaches to evaluating publication activity. Statistical methods were used to analyse the development and spread of unscrupulous journals and junk scientific conferences; the methods of expert assessments and content analysis were also applied. The information base is the corpus of leading Russian and foreign researchers’ works on scientometric evaluation of publications and the use of special methods of bibliometric analysis. The multiplicity of fraud issues in science still unresolved and the palliative measures taken make it possible to assess the harmfulness of scientometric formalism from a new perspective. The main features of junk journals are identified: lack of peer review, international collaboration and target audience; multidisciplinarity; demand-based journal volumes; a short publication cycle, etc. In the article, we assess the dynamics and spread of such journals in Russian science, identify effective measures to counteract law-quality publications, such as retraction and a combination of altmetric and bibliometric methods for evaluating studies. Another focus of analysis is to describe the practice of junk conferences and provide criteria for their identification.

With the continuous application of intelligent technology, Virtual Reality (VR) technology has become a hot topic of development. VR has unique advantages in the field of the teaching due to its characteristics of immersion, interaction and sociality. Therefore, it is necessary to pay attention to the influencing factors of VR teaching on learning effect, to improve the quality of courses through improvement of relevant influencing factors and to help to reverse further development of VR technology. A questionnaire survey on influencing factors of teaching application of VR technology on the learning effect of college students was conducted. Through data collection of students of various majors and grades in multiple comprehensive universities, statistical analysis and regression empirical analysis were carried out. Results show that different majors, grades, and students' autonomous learning ability have different influences on the teaching application of VR technology. In addition, there are many influencing factors such as network fluency, situational sense of interaction, teachers' teaching ability and the difficulty of course design, etc. According to the conclusions, some suggestions on improving VR teaching and learning effect are put forward. It is expected to improve the learning effect and efficiency of college students under the application of VR teaching, and promote the further development of VR teaching. [ABSTRACT FROM AUTHOR]

Background: While database studies have become more prevalent in the literature, there is concern over their value. In addition, the questions they are suitable to answer are limited. Questions/Purposes: We sought to determine the incidence of database studies in the orthopedic literature and in each subspecialty. In addition, we wanted to assess the impact of database studies on the literature by determining whether citations and Altmetric Attention Scores (AAS) varied by study type (studies using internal or external databases and those not using databases). Methods: We searched PubMed for articles published in impactful orthopedic surgery journals in the year 2018. All articles were discoverable on the Altmetric explorer portal database. Impact was determined by journal impact factor. Study design, subspecialty, number of citations, and AAS were obtained. Univariable analyses were conducted between study type, demographic variables, and the outcome of either citation count or AAS. Multivariable analyses were performed to identify independent predictors of the primary outcomes. Subgroup analyses were performed to differentiate the impact of external and internal database studies compared with non-database studies. Results: A total of 2684 total articles were eligible for inclusion. Of these, 366 studies (13.6%) were database studies. Hip and knee articles had the greatest incidence of database studies. Database studies had significantly more citations (5.9 vs 4.0) and significantly higher AAS (12.8 vs 11.3) compared with non-database studies. External database studies had significantly more citations (6.7 vs 4.8) and significantly higher AAS (14.0 vs 10.7) than internal database studies. Internal database studies had higher traditional citation counts but similar AAS to non-database studies. Conclusions: In 2018, database studies in well-reputed orthopedic journals had a greater number of citations but similar AAS compared with non-database studies. Further studies are warranted.

In order to evaluate the structural performance and working state of the newly built prefabricated bridge, the single girder static load test, the whole bridge static and dynamic load test and the finite element simulation analysis were carried out on the 40 m T beam section of the Jiulinggang bridge of suide expressway. Through the static load test, the strain and deflection of the control section of the single beam and the bridge stage were tested, and the finite element calculation results were compared and analyzed. The natural vibration characteristics of the bridge, the dynamic effect and the impact effect under different driving speeds were obtained by the pulsation test and the driving test. The research results show that, the structural strain and deflection calibration coefficients of single girder and full bridge under static load all meet the requirements of the specification, and the relative residual strain and displacement after unloading are far less than 20% of the specification, and the structural bearing capacity is good. The deflection, strain value and load lateral distribution coefficient of the side beams at all levels of loading are all larger than those of the middle beams, and the overall deformation and stress distribution are relatively uniform, and the torsional stiffness and strength of the structure have a certain safety reserve. The measured damping ratio of the pulsation test is 1. 139%, which is less than 5% specified in the specification, with good dynamic characteristics and good energy dissipation performance during the vibration of the structural system. In the driving test, with the increase of the vehicle speed, the dynamic effect of the structure is more obvious, and the dynamic deflection, dynamic strain and impact coefficient have a tendency to increase obviously, the measured impact coefficients range from 0. 065 to 0. 133, indicating that the bridge deck has good flatness.

Objective: This study aims to identify determinants of high impact, measured by Impact Factor (IF) and Eigenfactor score, among otolaryngology journals. Methods: Bibliometric data of "otorhinolaryngology" journals were collected from the Journal Citation Reports (JCR) database. For the years 2009–2020, we collected normalized Eigenfactor score, 5‐year IF, immediacy index, fraction of IF from journal‐self citation, proportion and magnitude of published citable articles, and total citation counts. High‐IF and ‐Eigenfactor journals were considered those within the top‐quartile of that metric each respective year. Results: High‐IF and ‐Eigenfactor otolaryngology journals displayed higher 5‐year IFs, immediacy indexes, and IF without self‐citation (p <.05 for all years) including total citations counts and citable articles when ranked by Eigenfactor (p <.05 for all years). Otolaryngology IF correlated with 5‐year IF and immediacy index within the same year (p <.05 for all years) and from previous years (p <.05 for all years; p <.05 for 2017‐2018; p >.05 for 2009‐2016). Eigenfactor correlated with 5‐year IF, total citation counts, and citable articles within the same year (p <.05 for all years) and previous years (p <.05 for 2013–2018). Multilinear regression revealed that 5‐year IF (p <.05 for 2009–2018) and immediacy index from the prior 2 years (p <.05 for 2017‐2018; p >.05 for 2009‐2016) predicted 2019 IF. Similarly, 5‐year IF, total citation counts, and citable articles (p <.05 for 2013–2018) predicted 2019 Eigenfactor score. Conclusion: Sustained publication of impactful articles is the dominant driver of high IF and Eigenfactor score. Eigenfactor score reflects a unique evaluation of otolaryngology journals; ranking otolaryngology journals by their Eigenfactor scores significantly alters journal ranking compared to ranking by IF. Level of evidence: NA. Bibliometrics, most prominently the Impact Factor, are commonly used not only as a measure of a journal's impact and influence but also as an unintended measure of prestige and quality for a journal, the articles it publishes and its authors. Herein, we study journal characteristics and metrics to identify the factors that most determine Impact Factor and Eigenfactor Score for journals in the field of otolaryngology. We show that these bibliometrics of journal impact are most dominantly determined by the consistent publication of timely, impactful, and well‐cited articles. [ABSTRACT FROM AUTHOR]

This paper examines various models of academic publishing and considers their relative advantages for authors, readers, academic institutions and society. Relevant factors driving authors' choice of the journal include the journal's scope, reputation and publishing model used. Authors' choices are shaped by the expectations of academic institutions and strongly determine both access to readers and the benefits to society. From an analysis of 174 journals in the tourism and hospitality field, four publication models are identified and compared: 'subscription-only' and the 'Green', 'Gold' and 'Platinum' open-access models. The findings of a survey of 42 editors of journals in the field are then presented. These suggest that subscription-based journals (subscription-only or hybrid) tend to be owned by commercial publishing companies and have the highest reputation, as measured by their position in one or more indexing systems. They also tend to have significantly larger paper submissions than open-access journals, especially those that use the Platinum open-access model. While some commentators have suggested that editors of open-access journals with article-processing charges may be tempted to lower their scientific standards to maximize revenues, no evidence was found that such journals have higher acceptance rates than their subscription-based equivalents.

Purpose: Editorial Board Metrics (EBM) is used to determine the performance, effectiveness, and role of editorial board members and journal editors in policymaking and designing a roadmap for the future of journals. This s tudy analyzed and evaluated indexed journals in health sciences, biological sciences, arts, and humanities using EBM. Method: Social Network Analysis (SNA) was used to visualize the interconnections of editorial board members and journals. For this purpose, centrality indices were used, including degree centrality, closeness centrality, and betweenness centrality. Data analysis was performed in two descriptive and inferential sections for editorial board members (2813 individuals) and journals (200 journals) using s tatis tical methods such as frequency, percentage, mean, Kendall's Tau-b coefficient, Chi-square tes t, and software such as UCINET, SPSS, Net Draw, and Python. Findings: The research findings on the s tatus of the impact factor of journals indicate that in the field of humanities and arts, the "Journal of Applied Issues in Islamic Education" with 1.095 has the highes t impact factor. In the field of health sciences, "Iranian Journal of Ageing (Salmand)- Waiting Lis t" with 0.446 has the highes t impact factor, and in the field of biological sciences, "Plant Genetic Researches - Primary Lis t" with 0.37 has the highes t impact factor in each subject area. Some journals in the fields of humanities and arts have a high self-citation rate, including journals that have over 80% self-citation in the field of humanities and arts, such as "The Journal of Nahjolbalagheh" (77.80%) and "Journal of Kurdish Literature" and "Persian Language and Iranian Dialects" (100%). Ahad Faramarz Gharamaleki (Professor at the University of Tehran) and Mohammad Hassan Ghadrdan Gharamaleki (Professor at the Ins titute of Culture and Islamic Thought) have the highes t level of interlocking (frequency 5). Of 368 individuals with co-authorship, 333 are male, and 35 are female. Regarding academic rank, the "Professor" with 71.76% and "the Associate Professor" with 15.48% have the highes t share in the editorial board community. Conclusion: Of the 2,813 individuals who collaborated in 200 journals, 368 editorial board members had to interlock. The results indicate a significant negative relationship between the impact factor and the interlocking of the social science research journals and between the number of citations received by journals and their interlocking. Furthermore, there is a correlation between a rise in journal quartiles and a decrease in interlocking. According to the results, the number of journal quartiles is a significant negative predictor of interlocking. The Immediacy Index (II) of journals, the Median Impact Factor (MIF) in the macro subject, the number of articles, and the self-citation index are not significant predictors of interlocking. Considering the role of editorial board members in the development and quality improvement of journals through reviewing and selecting topics, the effort to form more diverse editorial boards with less interlocking will not only bring more diverse research output to the publishing world, deposit; which will create a positive competitive environment with a broader range of votes.

Many factors influence an author's choice for journal submission, including journal impact factor and publication speed. These and other bibliometric data points have not been assessed in journals dedicated to neurosurgery. Eight leading neurosurgery journals were analyzed to identify original articles and reviews, collected via randomized, stratified sampling per published issue per year from 2016 to 2020. Bibliometric data on publication speed were gathered for each article. Journal impact factor, article processing fees, and open access availability were determined using Clarivate Journal Citation Reports. Correlation analysis and a linear regression model were used to estimate the effect of impact factor and publication year on publication speed. Across the 8 neurosurgery journals, 1617 published articles were reviewed. The mean (standard deviation) time from submission to acceptance (SA) was 131 (101) days, from acceptance to online publication was 77 (61) days, and from submission to online publication was 207 (123) days. Higher impact factors correlated with longer publication times for all metrics. Later years of publication correlated with longer times from SA and submission to online publication. For each point increase in a journal's impact factor, multivariate regression modeling estimated a 19.2-day increase in time from SA, a 19.7-day increase in time from acceptance to online publication, and a 38.9-day increase in time from submission to online publication (P < 0.001 for all). Publication speeds vary widely among neurosurgery journals and appear to be associated with the journal impact factor. Time to publication increased over the study period. [ABSTRACT FROM AUTHOR]

The journal Cephalalgia was founded in 1980 and was first published in 1981. The foundation was mainly laid by Ottar Sjaastad who also served as the first Editor-in-Chief. In the early years, Cephalalgia was published in Scandinavia and was owned by the Norwegian Migraine Society. It became the official journal of the International Headache Society in 1984 and in 1993 ownership of Cephalalgia was transferred to International Headache Society. The publisher changed in 2000 and then again in 2009. The success of Cephalalgia can be seen by the almost continuous rising of its impact factor and by the increasing number of issues including supplements and special issues. In the future, Cephalagia will become more digital and open access. [ABSTRACT FROM AUTHOR]

In order to study the vehicle impact effect on the fatigue assessment for steel bridge decks, the segmental finite element model is built of a continuous steel box girder bridge, and 7-day Weigh-in-Motion(WIM) data of Lianyungang-to-Horgos Expressway is selected to carry out fatigue assessment of typical details. The influence law of impact factors on the fatigue assessment result is analyzed, and the applicability of impact factors in different current specifications is studied. Research results show that the vehicle impact effect has a significant influence on the fatigue assessment results of steel bridge decks. Obvious differences exist in impact effects of different details, the impact effect of rib-to-deck detail is the largest, and the rib-to-rib detail is the smallest. The bridge deck pavement condition has great influence on the impact effect of steel bridge deck, fatigue assessment result of “worse” pavement condition is 3. 30-3. 91 times of “excellent” pavement condition. The vehicle impact effect should be fully considered when the fatigue assessment is performed, and reasonable impact factors should be adopted according to pavement conditions and detail types.

Despite regularly being criticized, the Impact Factor (IF) remains a widely used journal analysis metric. In the Water Resources category of the Web of Science, a thorough investigation of the reliability of this metric is lacking. This study analyzed the citation records of the top 10 journals from 2002 through 2021 for the last two decades. Important to note, there are inconsistencies in the Web of Science database. Contradictory to many fields, few papers are uncited. However, the Simpson paradox applies. More specifically, on the one hand, the correlation between citations to papers 7 years post publication and 1 or 2 years post publication (which determine the IF) has increased, which supports this metric. On the other hand, many of the most highly cited papers at the time of the IF calculation are lowly cited 5 years afterward. Additionally, most currently very highly cited papers were relatively uncited when they were used in the IF calculation. This raises doubt about the usefulness of this metric. For a limited number of journals, papers from individual nations strongly influence the IF. Also, for a few journals, the IFs are strongly influenced by review papers, but leaving these out of the IF does change the top 3 and 10 of the rankings. The general conclusion is that IFs do contain some valuable information about the journals' citation impact, but that using them to rank journals is questionable practice. Plain Language Summary: Impact Factors (IFs) continue to be very frequently used to evaluate researchers' publication records. They are calculated in a very simplistic manner, and are essentially an attempt to summarize a very complicated issue (publication quality) into one single metric. This paper shows that care must be taken when applying this practice. Not only does the data set contain errors, there are a number of other reasons why these IFs are not reliable indicators of a journal's quality. Key Points: In many cases the calculation of the Impact Factor (IF) by the Web of Science is contradictory with their own dataAnother number of issues have been identified which raise doubt on the IF as a measure of journal qualityA number of recommendations for a better use of the literature databases have been made [ABSTRACT FROM AUTHOR]

The impact factor (IF) assessment of a four-span non-prismatic continuous and an equivalent integral railway bridge under the action of high-speed moving train loads is conducted in this study. Critical analysis of the full-scale three-dimensional finite element (FE) bridge models is done to investigate the differences in the IFs of all the spans of the two-track railway bridge under various loading conditions. A simplified approach is proposed to identify the dynamic IF values. The results show that for a continuous bridge, with the increase in the load on the bridge, IF coefficients reduce from 0.195 to 0.102. However, for the integral bridge, and considered loading conditions, almost similar IF coefficients (0.100) are obtained. For the intermediate spans, the resonance phenomenon for the integral bridge is achieved at lower speeds compared to the equivalent continuous bridge.

Commenced from 1975 and calculated based on the number of overall journal citations in a year divided by the number of citable publications in the preceding two years, Journal Impact Factor (JIF) became a convenient and conventional proxy to appraise a journal's trustworthiness and its scholarly impact in a given field (1).

Based on the World Register of Marine Species (WoRMS), there are currently c. 242,000 known valid marine species living in the world's oceans and marine biota continue to be discovered and named steadily at a current average of 2,332 new species per year. The “average” newly described marine species is a benthic crustacean, annelid, or mollusc between 2 and 10 mm in size, living in the tropics at depths of 0–60 m, and represented in the description by 7–19 specimens. It is described after a shelf life of 13.5 years in an article with two to three authors in a journal with an IF
