It has been stated that citation behavior in general is affected by field-dependent factors, which may invalidate comparisons not only across disciplines but even within different fields of research of one discipline. Atomic number 1; atomic weight 1. The lightest and most abundant element in the universe, normally consisting of one proton and one electron. The exclusion of conference proceedings papers is a particular problem for scholars in , where conference proceedings are considered an important part of the literature. Journal of the American Society for Information Science and Technology.

However, Hirsch noted that values of h will vary between different fields. The h-index is an that attempts to measure both the and of the of a or scholar. However, this finding was contradicted by another study by Hirsch. First we order the values of f from the largest to the lowest value. The h-index serves as an alternative to more traditional journal metrics in the evaluation of the impact of the work of a particular researcher. The website has played a significant role in my professional career development.

The index can also be applied to the productivity and impact of a as well as a group of scientists, such as a department or university or country. Hirsch has demonstrated that h has high predictive value for whether a scientist has won honors like membership or the. A value of about 18 could mean a full professorship, 15—20 could mean a fellowship in the , and 45 or higher could mean membership in the. A successive Hirsch-type-index for institutions has also been devised. For example, the Meho and Yang study found that Google Scholar identified 53% more citations than Web of Science and Scopus combined, but noted that because most of the additional citations reported by Google Scholar were from low-impact journals or conference proceedings, they did not significantly alter the relative ranking of the individuals.

Of course this method does not deal with academic age bias. During the period January 1, 2000 — February 28, 2010, a physicist had to receive 2073 citations to be among the most cited 1% of physicists in the world. When compared with a video creator's total view count, the h-index and g-index better capture both productivity and impact in a single metric. The index was suggested in 2005 by , a physicist at , as a tool for determining ' relative quality and is sometimes called the Hirsch index or Hirsch number. Distinguish your posting by adding a logo and making it a featured notice additional fees apply. However, later work has shown that since h-index is a cumulative measure, it contains intrinsic auto-correlation that led to significant overestimation of its predictability. The index is designed to improve upon simpler measures such as the total number of citations or publications.

Hydrogen is used to make rocket fuel, synthetic ammonia, and methanol, to hydrogenate fats and oils, and to refine petroleum. A detailed study showed that the Web of Science has strong coverage of journal publications, but poor coverage of high impact conferences. Therefore, these disciplines have lower citation thresholds in the Essential Science Indicators, with the lowest citation thresholds observed in social sciences 154 , computer science 149 , and multidisciplinary sciences 147. The development of physical theories of electron orbitals in hydrogen was important in the development of quantum mechanics. It might be simpler to divide citation counts by the number of authors before ordering the papers and obtaining the h-index, as originally suggested by Hirsch.

This method has not been readily adopted, perhaps because of its complexity. Each database is likely to produce a different h for the same scholar, because of different coverage. Biochemical and Biophysical Research Communications. The h-index is an that attempts to measure both the and of the of a or scholar. The discussion areas are valuable as well; having the opportunity to network with such a vast expanse of scholars is remarkable.

Hydrogen atoms are relatively electropositive and form hydrogen bonds with electronegative atoms. For the economic measure, see. Thus, the true predictability of future h-index is much lower compared to what has been claimed before. It has been suggested that in order to deal with the sometimes wide variation in h for a single academic measured across the possible citation databases, one should assume false negatives in the databases are more problematic than false positives and take the maximum h measured for an academic. This method has not been readily adopted, perhaps because of its complexity. The active community of researchers, teachers, and scholarly professionals already collaborating through H-Net's 180+ public networks is a highly motivated, self-selecting audience with established networks within and outside of the academy. From July 2011 have provided an automatically-calculated h-index and within their own profile.

In contrast, if the same publications have 25, 8, 5, 3, and 3 citations, then the index is 3 because the fourth paper has only 3 citations. For example, the Meho and Yang study found that Google Scholar identified 53% more citations than Web of Science and Scopus combined, but noted that because most of the additional citations reported by Google Scholar were from low-impact journals or conference proceedings, they did not significantly alter the relative ranking of the individuals. For example, if we have a researcher with 5 publications A, B, C, D, and E with 10, 8, 5, 4, and 3 citations, respectively, the h-index is equal to 4 because the 4th publication has 4 citations and the 5th has only 3. As these metrics are percentages, they are intended to give a qualitative description to supplement the quantitative h-index. The three h 2 metrics measure the relative area within a scientist's citation distribution in the low impact area, h 2 lower, the area captured by the h-index, h 2 center, and the area from publications with the highest visibility, h 2 upper. For the economic measure, see.
