H-index is an index that attempts to measure the productivity and impact of published work of scientists. H-index has several advantages - it combines productivity with echo, is not sensitive to extreme values in terms of articles without citation or to articles with above-average number of citations and directly enables the identification of the most relevant articles with regard to the number of citations received. H-index has great potential in the academic community, but it still has not realistic indicator of the quality of work of one author...

Several technical indicators have been proposed to assess the impact of authors and institutions. Here, we combine the h-index and the PageRank algorithm to do away with some of the individual limitations of these two indices. Most importantly, we aim to take into account value differences between citations-evaluating the citation sources by defining the h-index using the PageRank score rather than with citations. The resulting PR-index is then constructed by evaluating source popularity as well as the source publication authority...

PURPOSE: Gender disparities within academic promotion have been reported in several medical specialties. Female representationin association with research productivity has not been reported among academic dermatologists. As research productivity is a heavily weighted factor in determining promotion, we sought to determine whether gender disparities in academic rank and scholarly impact, measured by the h-index, exist in academic dermatology. METHODS: In 2015, the authors determined gender and academic rank using academic dermatology department websites...

Hemolysis frequently causes preanalytical errors in laboratory measurements. We aimed to develop a quality improvement indicator for evaluating the extent of inappropriate procedures causing hemolysis in clinical samples collected in medical care units. We defined the threshold value of the hemolysis index (H index) causing significant interference with analyte measurement and analyzed the H index values of clinical samples in relation to the threshold. The H index threshold value causing a 10% bias in the measurement of lactate dehydrogenase was found to be 25...

Professors of Nursing have an important part to play in leading the profession, both nationally and internationally, generating new knowledge and ensuring practice is based on the best available evidence. A number of authors have been critical of this leadership group, both in terms of their academic performance and clinical credibility. Watson et al (2016), for example, using the h-index as a measure of research quality and productivity, demonstrated that a substantial proportion of the nursing professoriate had a rather modest publication record...

Indexation status matters for scholarly journal prestige and trust. The performance of Malaysian medical journals at the international level is gauged through the global citation databases, and at the national level through MyCite, a national citation indexing system. The performance indicators include journals publication productivity, the citations they garner, and their scores on other bibliometric indices such as journal impact factor (IF), and h-index. There is a growing consciousness amongst journal editorials to improve quality and increase chances of getting indexed in MyCite...

Moderate exercise positively impacts innate immune functions, bringing about a better resistance against infections and general immunosurveillance. Exercise of high workloads (i.e., high intensity and/or duration) such as elite marathon, on the other hand, may have detrimental effects over immune function, but neither how long nor how intense should be the exercise sessions to be deleterious is known, this being a matter of intense dispute. Exercise is, at the same time, one of the most powerful inducers of the 70 kDa family of heat shock proteins (HSPAs, formerly known as HSP70s), which are protein chaperones characterized by a marked anti-inflammatory potency, when located intracellularly (iHSPA), but may act as pro-inflammatory cytokines if in the extracellular space (eHSPA)...
