We discuss recent activities in the SciDAC Applied Math Institute for Combinatorial Scientific Computing and Petascale Simulations (CSCAPES).

BACKGROUND Citation counts are often regarded as a measure of the utilization and contribution of published articles. The objective of this study is to assess whether statistical reporting and statistical errors in the analysis of the primary outcome are associated with the number of citations received. METHODS We evaluated all original research articles published in 1996 in four psychiatric ...

A thorough review of the literature is the basis of all research and evidence-based practice. A gold-standard efficient and exhaustive search strategy is needed to ensure all relevant citations have been captured and that the search performed is reproducible. The PubMed database comprises both the MEDLINE and non-MEDLINE databases. MEDLINE-based search strategies are robust but capture only 89%...

Introduction. We present a new bibliometric indicator to measure journal specialisation over time, named the focus factor. This new indicator is based on bibliographic coupling and counts the percentage of re-citations given in subsequent years. Method. The applicability of the new indicator is demonstrated on a selection of general science journals and on a selection of medical journals. The r...

CONTEXT AND OBJECTIVE Impact factors are currently the bibliometric index most used for evaluating scientific journals. However, the way in which they are used, for instance concerning the study or journal types analyzed, can markedly interfere with estimate reliability. This study aimed to analyze the citation distribution pattern in three Brazilian journals of general medicine. DESIGN AND S...

Introduction: Citation tracking is a bibliometrics method to analyze the scientific impact of journal articles which can be done through Scopus (SC), Google Scholar (GS), or ISI web of knowledge (WOS). In the current study, we analyzed the citations to 2006-2012 articles of Iranian Journal of Nuclear Medicine (IJNM) in the SC and GS. Methods: We retrieved the relevant data from SC and GS offici...

Bibliometric indicators are used to assess research performance. The goal of this study was to explore publication output to construct a picture of orthopedics that may be beneficial to researchers and orthopedic specialists. All orthopedics articles published in 61 journals from 2000 to 2011 were retrieved from the Science Citation Index Expanded database. The numbers of articles, citations, a...

PURPOSE The Accreditation Council for Graduate Medical Education and the Residency Review Committee for Internal Medicine (RRC-IM) evaluate internal medicine residency programs using a list of 301 program requirements. The authors investigated which requirements, program demographics, and site-visitor characteristics were the strongest predictors of accreditation. METHOD The authors surveyed ...

Tomotherapy is the delivery of intensity modulated radiation therapy using rotational delivery of a fan beam in the manner of a CT scanner. In helical tomotherapy the couch and gantry are in continuous motion akin to a helical CT scanner. Helical tomotherapy is inherently capable of acquiring CT images of the patient in treatment position and using this information for image guidance. This revi...

OBJECTIVES The research sought to determine the publication types cited most often in public health as well as the most heavily cited journal titles. METHODS From a pool of 33,449 citations in 934 articles published in the 2003-2005 issues of American Journal of Public Health, 2 random samples were drawn: one (n = 1,034) from the total set of citations and one (n = 1,016) from the citations t...
