This paper discusses the Indian chemical research activity during 1987 to 2007 using Scopus database. It tries to quantify the national contribution to world efforts, and identify areas of relative strengths and weaknesses. It also models out the trend of growth in the output of Indian chemical research to world as a whole and in sub-fields of chemical science. These details have been discussed...
We model Science and Technology (S&T) systems as complex systems and propose to use the mathematical tools developed within the spin-glasses literature to evaluate similarity within systems and between systems in a unified manner. Our measure is based on the ‘overlap’ of disciplinary profiles of a set of S&T systems. The investigation of the distribution of the overlaps provides useful insights...
The last few years have seen the emergence of several Open Access (OA) options in scholarly communication, which can broadly be grouped into two areas referred to as gold and green roads. Several recent studies showed how big the extent of OA is, but there have been few studies showing impact of OA in the visibility of journals covering all scientific fields and geographical regions. This resea...
Predicting future high impact academic papers is of benefit to a range of stakeholders, including governments, universities, academics, and investors. Being able to predict ‘the next big thing’ allows the allocation of resources to fields where these rapid developments are occurring. This paper develops a new method for predicting a paper’s future impact using features of the paper’s neighbourh...
Policy makers and managers sometimes assess the share of research produced by a group (country, department, institution). This takes the form of the percentage of publications in a journal, field or broad area that has been published by the group. This quantity is affected by essentially random influences that obscure underlying changes over time and differences between groups. A model of resea...
A statistical analysis of full text downloads of articles in Elsevier's ScienceDirect covering all disciplines reveals large differences in download frequencies, their skewness, and their correlation with Scopus-based citation counts, between disciplines, journals, and document types. Download counts tend to be two orders of magnitude higher and less skewedly distributed than citations. A mathe...
BACKGROUND Web of Science, Scopus, and Google Scholar are three major sources which provide h-indices for individual researchers. In this study we aimed to compare the h-indices of the academic pediatricians of Mashhad University of Medical Sciences obtained from the above mentioned sources. METHOD Academic pediatrician who had at least 5 ISI indexed articles entered the study. Information re...
هدف: با توجه به اهمیت پژوهشهای بین رشتهای، این پژوهش با هدف مطالعه رابطع شاخصهای مرکزیت با بهرهوری علمی و کارآیی پژوهشگران حوزه آموزش از دور انجام شده است. روش: پژوهش از نوع مطالعات کاربردی علمسنجی است که از فن تحلیل شبکههای اجتماعی استفاده میکند. جامعه آماری پژوهش 40252 مدارک علمی پژوهشگرانی است که در پایگاه ISI از 1992 تا 2012 نمایه شده است. برای تحلیلهای شبکهای و آماری از نرمافزار...

We compare the network of aggregated journal-journal citation relations provided by the Journal Citation Reports (JCR) 2012 of the Science and Social Science Citation Indexes (SCI and SSCI) with similar data based on Scopus 2012. First, global maps were developed for the two sets separately; sets of documents can then be compared using overlays to both maps. Using fuzzystring matching and ISSN ...
