The increase in the size of the scientific community created an explosion in scientific production. We have analyzed the dynamics of biomedical scientific output during 1957-2007 by applying a bibliometric analysis of the PubMed database using different keywords representing specific biomedical topics. With the assumption that increased scientific interest will result in increased scientific ou...

UNLABELLED Among the many bibliometric criteria used to evaluate biomedical journals, the impact factor is the most commonly used. Despite its limitations, it quantifies the influence of a journal on secondary publications. It does not however evaluate the practical usefulness of primary documents. Usefulness is field-related and varies greatly among specialities. We introduce a new bibliograph...

Tests are described comparing the sensitivity of the Erickson dipole feeds with the new strut-straddling Modified J-Pole (MJP) feeds using the new VLA Lowband receivers in the 54-86 MHz window. These tests show that the sensitivity of the MJP feeds for the “B” mounting position is comparable to the Erickson dipoles. For the “C” mounting position the MJP sensitivity is a factor of two worse than...

AIM To analyse current ranking (2013) of institutions, journals and researchers in the Republic of Macedonia. MATERIAL AND METHODS the country rankings of R. Macedonia were analyzed with SCImago Country & Journal Rank (SJR) for subject area Medicine in the years 1996-2013, and ordered by H-index. SCImago Institutions Rankings for 2013 was used for the scientific impact of biomedical instituti...

Animal research is not only regulated by legislation but also by self-regulatory mechanisms within the scientific community, which include biomedical journals' policies on animal use. For editorial policies to meaningfully impact attitudes and practice, they must not only be put into effect by editors and reviewers, but also be set to high standards. We present a novel tool to classify journals...

This study presents a ranking list of 35 managementand 28 clinical-centered e-health academic journals developed based on a survey of 398 active researchers from 46 countries. Among the management-centered journals, the researchers ranked Journal of the American Medical Informatics Association and Journal of Medical Internet Research as A+ journals; among the clinical-focused journals, they ran...

This research attempts to seek changing patterns of raw data availability and their correlations with implementations of open mandate policies. With a list of 13,785 journal articles whose authors archived datasets in a popular biomedical data repository after these articles were published in journals, this research uses regression analysis to test the correlations between data contributions an...

BACKGROUND AND OBJECTIVES The development of electronic editions of scientific journals and the rapid spread of scientific information might modify the pattern the bibliographic citations, and thus the impact factor and quality of journals. We assessed changes in the impact factor over years of a number of journals and whether the presence of an electronic version of the journal was associated ...

In the present paper, we have created several novel journal similarity metrics. The MeSH odds ratio measures the topical similarity of any pair of journals, based on the major MeSH headings assigned to articles in MEDLINE. The second metric employed the 2009 Author-ity author name disambiguation dataset as a gold standard for estimating the author odds ratio. This gives a straightforward, intui...
