BACKGROUND: Despite its impact on female health worldwide, no efforts have been made to depict the global architecture of ovarian cancer research and to understand the trends in the related literature. Hence, it was the objective of this study to assess the global scientific performance chronologically, geographically and in regards to economic benchmarks using bibliometric tools and density equalizing map projections. METHODS: The NewQIS platform was employed to identify all ovarian cancer related articles published in the Web of Science since 1900...

Lithium salts have been used to treat psychiatric disorders since the 1940s and are currently used in prophylaxis and treatment of depression and bipolar disorder. Therefore, we conducted this study to assess lithium toxicity-related publications using bibliometric approaches from a health point of view to assess global research trends in the lithium toxicity field to offer guidance to future research in this field. The data were retrieved from the online version of Scopus database on 6 August 2016. All records with the term "lithium" in the title were retrieved, and those related to lithium toxicity were evaluated...

OBJECTIVE: Academic productivity is measured under many domains: number of high impact publications, objective bibliometrics, securing extra-mural funding, etc. Citation impact is measured by an objective bibliometric called h-index. Securing funding from the National Institute of Mental Health (NIMH) is considered prestigious in the field of psychiatry. It is unknown if NIMH takes into consideration the author's h-index during the grant review process. The goal of this study was to determine the correlation between a principal investigator's (PI's) h-index and the NIMH funding...

Pulmonary hypertension (PH) is characterized by the increase of the mean pulmonary arterial pressure in the lung circulation. Despite the large number of experimental and clinical studies conducted on pulmonary hypertension, there is no comprehensive work that analyzed the global research activity on PH so far. We retrieved the bibliometric data of the publications on pulmonary hypertension for two periods from the Web of science database. Here, we set the first investigation period from 1900 to 2007 (t1) due to the cited half life of articles and the relating difficulties to interpret the citation parameters...

Networks are used for modeling numerous technical, social or biological systems. In order to better understand the system dynamics, it is a matter of great interest to identify the most important nodes within the network. For a large set of problems, whether it is the optimal use of available resources, spreading information efficiently or even protection from malicious attacks, the most important node is the most influential spreader, the one that is capable of propagating information in the shortest time to a large portion of the network...

BACKGROUND: The Hirsch index (h-index) is widely recognized as a reliable measure of academic productivity. While previous studies have applied the h-index to surgical disciplines, none have analyzed microsurgery faculty. This manuscript aims to examine the h-index of microsurgery fellowship faculty to categorize its applicability to microsurgeons as a determinant of academic output. METHODS: Faculty demographics and institution characteristics were obtained from the American Society of Reconstructive Microsurgery (ASRM) and official program websites...

BACKGROUND: Pediatric surgery is one of the most difficult surgical fellowships to obtain. It requires stellar academic credentials and, often, dedicated time pursuing research. It is unknown, however, if pediatric surgeons maintain high academic output as faculty members. We hypothesized that the majority of pediatric surgeons do not pursue robust research activities as faculty, and therefore, over time, their academic productivity decreases. METHODS: Numbers of publications, citations, H-index, and NIH funding rates were determined for 4354 surgical faculty at the top-55 NIH based departments of surgery using websites, Scopus, NIH RePORTER, and Grantome...

BACKGROUND: Increasing evidence suggests that depot medroxyprogesterone acetate (DMPA) and intravaginal practices may be associated with an increased risk of HIV infection; however the mechanisms are not fully understood. This study evaluated the effect of DMPA and intravaginal practices on the genital mucosal proteome and microbiome to gain mechanistic insights. METHODS: Cervicovaginal secretions from 86 Kenyan women, including self-reported DMPA (n=23) and non-hormonal contraceptive users (n=63), and women who practice vaginal drying (n=46) were analyzed using tandem-mass spectrometry in a cross sectional manner...

Bibliometric indicators such as journal impact factors, h-indices, and total citation counts are algorithmic artifacts that can be used in research evaluation and management. These artifacts have no meaning by themselves, but receive their meaning from attributions in institutional practices. We distinguish four main stakeholders in these practices: (1) producers of bibliometric data and indicators; (2) bibliometricians who develop and test indicators; (3) research managers who apply the indicators; and (4) the scientists being evaluated with potentially competing career interests...

RATIONALE AND OBJECTIVES: h-Index has been proposed as a useful bibliometric measure for quantifying research productivity. In this current study, we analyzed h-indices of editorial board members of Radiology journals and tested the hypothesis that editorial board members of Radiology journals with higher impact factors (IF) have higher h-indices. MATERIALS AND METHODS: Sixty-two Radiology journals with IF >1 were included. Editorial board members were identified using the journals' websites...

Professional decisions about hiring, tenure, promotion, funding, and honors are informed by assessments of scholarly impact. As a measure of influence, citations are produced by experts but accessible to nonexperts. The h index is the largest number h such that an individual has published at least h works cited at least h times apiece. This is easy to understand and calculate, as or more reliable and valid than alternative citation measures, and highly robust to missing or messy data. Striving for a large h index requires both productivity and influence, which provides healthy incentives for researchers striving for eminence through scientific impact...

Women are sparsely represented among psychologists honored for scientific eminence. However, most currently eminent psychologists started their careers when far fewer women pursued training in psychological science. Now that women earn the majority of psychology Ph.D.'s, will they predominate in the next generation's cadre of eminent psychologists? Comparing currently active female and male psychology professors on publication metrics such as the h index provides clues for answering this question. Men outperform women on the h index and its two components: scientific productivity and citations of contributions...

Gregory J Feist
In this article, I argue that scientific fame and impact exists on a continuum from the mundane to the transformative/revolutionary. Ideally, one achieves fame and impact in science by synthesizing two extreme career prototypes: intrinsic and extrinsic research. The former is guided by interest, curiosity, passion, gut, and intuition for important untapped topics. The latter is guided by money, grants, and/or what is being published in top-tier journals. Assessment of fame and impact in science ultimately rests on productivity (publication) and some variation of its impact (citations)...

BACKGROUND: Campylobacter species are widespread zoonotic pathogens. Campylobacter jejuni causes a form of gastroenteritis called campylobacteriosis. Campylobacter drug resistance is considered a serious threat. In order to better understand national and international research output on Campylobacter, we conducted this bibliometric overview of publications on Campylobacter. This study can be used to assess extent of interaction and response of researchers, food regulators, and health policy makers to global burden of campylobacateriosis...

Víctor B Arias, Fernando P Ponce, Daniel E Núñez
BACKGROUND: In the past decade, the bifactor model of attention-deficit/hyperactivity disorder (ADHD) has been extensively researched. This model consists of an ADHD general dimension and two specific factors: inattention and hyperactivity/impulsivity. All studies conclude that the bifactor is superior to the traditional two-correlated factors model, according to the fit obtained by factor analysis. However, the proper interpretation of a bifactor not only depends on the fit but also on the quality of the measurement model...

BACKGROUND: Glyphosate (N-phosphonomethylglycine) has been used as a broad-spectrum herbicide that has been widely used in the agricultural industry and also available for home use. The main aim of this study is to present a general overview of glyphosate intoxication-related publications from its introducing since the early 1970s using bibliometric technique. METHODS: On June 23, 2016, a literature search of the Scopus database was performed. We then extracted and analyzed the data using well-established qualitative and quantitative bibliometric indices: Publication year, affiliation, document type, country name, subject category, journal name, publishing language, and collaboration and citation patterns...

This article overviews unethical publishing practices in connection with the pressure to publish more. Both open-access and subscription publishing models can be abused by 'predatory' authors, editors, and publishing outlets. Relevant examples of 'prolific' scholars are viewed through the prism of the violation of ethical authorship in established journals and indiscriminately boosting publication records elsewhere. The instances of ethical transgressions by brokering editorial agencies and agents, operating predominantly in non-Anglophone countries, are presented to raise awareness of predatory activities...

Despite the frequent use of numerous quantitative indicators to gauge the professional impact of a scientist, little is known about how scientific impact emerges and evolves in time. Here, we quantify the changes in impact and productivity throughout a career in science, finding that impact, as measured by influential publications, is distributed randomly within a scientist's sequence of publications. This random-impact rule allows us to formulate a stochastic model that uncouples the effects of productivity, individual ability, and luck and unveils the existence of universal patterns governing the emergence of scientific success...
