Google Scholar Citations. Meneghini, R., & Packer, A. L. (2006). The data showed a significant difference in the mean citation rates between all pairs of resources except between Google Scholar and Scopus for condensed matter physics 2003.

Look at the following break-down to help make your choice. Google Scholar essentially serves as a database for scholarly literature, in much the same way that platforms like Pubmed.org and Web of Science do. The constant-potential condition is introduced through a Legendre transformation of the electronic energy with respect to the difference in the number of electrons in the two electrodes and their electrochemical potential difference, through which the Kohn–Sham equations for each electrode are variationally derived. That means it makes no difference in an article’s ranking if the article contains the query terms only once or multiple times. Though Google Scholar mentioned that it has the ability to find most of the citations to Social Sciences articles by 94%, while Web of Science and Scopus only covers 35% and 43%, Scopus has consistently provides wider coverage, especially for Social Science disciplines. 1. Google Scholar provides a simple way to broadly search for scholarly literature. Difference Between Google and DuckDuckGo Duck Duck Go can be used as a replacement for Google, but is very different. The preventive effect was further evaluated in two RCTs according to the degree of suppression of ovarian folliculogenesis and, thereby, the probability of ovulation and possibly pregnancy with the use of different methods of OC administration ( 22 , 23 ). On average, the top 50 articles in all four journals were cited 41 (WoS), 52 (Scopus, 26% higher citations count than WoS, range 8-42% in the different journals), and 93 times (Google Scholar, 116% higher citation count than WoS, range 42-203%). A measure of the peak-to-peak difference can be obtained by multiplying the values shown by a factor of π/2. The answer in both of these cases was "yes". Wiley Online Library Web of Science® Google Scholar. The results of the study show there is no significant difference in performance between online and traditional classroom students with respect to modality, gender, or class rank in a science concepts course for non-STEM majors. The purpose of this review is to provide an overview of the well-established sex-based differences in metabolism between men and premenopausal women during END, briefly discuss how these differences are mediated by oestrogen and highlight how these sex-based differences may impact adaptations to nutritional and exercise regimens intended to improve performance and/or health. In addition, it would be useful to have evidence of differences between subfields of education for such questions.

For articles published in 2000, Google Scholar provided significantly higher citation counts than either the Web of Science or Scopus, whilst there was no significant difference between the Web of Science and Scopus. comprehensive databases or services that represent a major challenge to Web of Science as the citation analysis tool than Scopus and Google Scholar. Difference Between Internal and External Environment What are internal and external environments? In multivariable analysis, however, only group-authored articles maintained a significant citation count difference among databases, and were associated with significantly fewer citations in Google Scholar. Google Scholar searches full text of articles but PubMed and Web of Science search only the citation, abstract, and tagging information. A CrossRef subscription takes care of that, I believe. We identify a fixed species difference in the relative concentrations of the cuticular hydrocarbons 2-methyl hexacosane and 5,9-pentacosadiene in Drosophila pseudoobscura and D. persimilis, and determine its genetic basis.In backcross males, this difference is due to genes on both the X and second chromosomes, while the other two major chromosomes have no effect. The Difference between Science and Technology in Birth. For Engineering, using Google Scholar roughly doubles citations, whereas even for the Sciences and the Life Sciences, the use of Google Scholar on average still increases citations by 50 %. 5 Comparison between Semantic Scholar and Google Scholar 5 Conclusion In conclusion, we recommend Semantic Scholar under certain conditions and caveats limited to researchers in the computer science and neuroscience field.
