The h-index has been applied to Internet Media, such as channels. The visual search recognizes patterns, colors and will match it to available similar items. One can be easily convinced that ranking in coauthorship networks should take into account both measures to generate a realistic and acceptable ranking. May not be redeemed for cash or cash equivalent. Each database is likely to produce a different h for the same scholar, because of different coverage. Numbers are very different in social science disciplines: The Impact of the Social Sciences team at found that social scientists in the United Kingdom had lower average h-indices.
The French orthography classifies words that begin with this letter in two ways, one of which can affect the pronunciation, even though it is a silent letter either way. Journal of the American Society for Information Science and Technology. 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. 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. The letter is silent in a , as in ah, ohm, dahlia, cheetah, pooh-poohed, as well as in certain other words mostly of French origin such as hour, honest, herb in but not and vehicle. Total number of papers does not account for the quality of scientific publications, while total number of citations can be disproportionately affected by participation in a single publication of major influence for instance, methodological papers proposing successful new techniques, methods or approximations, which can generate a large number of citations , or having many publications with few citations each.
The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications. In , the letter has five independent pronunciations, perhaps more than in any other language, with an additional three uses as a productive and non-productive member of a digraph. A scientific institution has a successive Hirsch-type-index of i when at least i researchers from that institution have an h-index of at least i. This method has not been readily adopted, perhaps because of its complexity. It was found that the distribution of the h-index, although it depends on the field, can be normalized by a simple rescaling factor. In , during the 20th century it was not used in the orthography of the Basque dialects in Spain but it marked an aspiration in the North-Eastern dialects. The form of the letter probably stood for a fence or posts.
Presence of a third-party trademark does not mean that RetailMeNot has any relationship with that third-party or that the third-party endorses RetailMeNot or its services. The haitch pronunciation of h has spread in England, being used by approximately 24% of English people born since 1982, and polls continue to show this pronunciation becoming more common among younger native speakers. 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. On average across the disciplines, a professor in the social sciences had an h-index about twice that of a lecturer or a senior lecturer, though the difference was the smallest in geography. 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.
Plus, you'll get bonus vouchers, birthday offers, and special invites to sales and events — straight to your inbox! Then, we look for the last position in which f is greater than or equal to the position we call h this position. Authorities disagree about the history of the letter's name. Whatever your preference, we can accommodate it better than anyone else in Omaha, Nebraska. Among 36 new inductees in the National Academy of Sciences in biological and biomedical sciences in 2005, the median h-index was 57. In addition, specific databases, such as the database can automatically calculate the h-index for researchers working in.
Find out what's hot and happening in the world of fashion, beauty, and home decor. This information should not be considered complete, up to date, and is not intended to be used in place of a visit, consultation, or advice of a legal, medical, or any other professional. It is possible to try the predictions using an online tool. A successive Hirsch-type-index for institutions has also been devised. External links has the text of the article.
Perhaps something in the middle is more your speed, like the. From July 2011 have provided an automatically-calculated h-index and within their own profile. Subscription-based databases such as and the provide automated calculators. Because only the most highly cited articles contribute to the h-index, its determination is a simpler process. You pay the return shipping for items returned by mail. We also have pre-owned options at our.
The index is designed to improve upon simpler measures such as the total number of citations or publications. You can make returns to the store for free. 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. 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. As these metrics are percentages, they are intended to give a qualitative description to supplement the quantitative h-index.
Despite this increasing number, the pronunciation without the sound is still considered to be standard in England, although the pronunciation with is also attested as a legitimate variant. Exclusions: Offer valid until March 25th in stores and on hm. A detailed study showed that the Web of Science has strong coverage of journal publications, but poor coverage of high impact conferences. Scopus has better coverage of conferences, but poor coverage of publications prior to 1996; Google Scholar has the best coverage of conferences and most journals though not all , but like Scopus has limited coverage of pre-1990 publications. Most coupons are shared by members of the RetailMeNot community, sometimes people add coupons intended for in store use only. Speakers could pronounce the h or not.
This article is about the index of scientific research impact. Scientists with high h 2 upper percentages are perfectionists, whereas scientists with high h 2 lower percentages are mass producers. The index works properly only for comparing scientists working in the same field; citation conventions differ widely among different fields. 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. This improvement can enhance the measurement sensitivity of the H-index. Third-party trademarks are the property of their respective third-party owners.
