An evaluation method used to assess the quality of research productivity and to provide priorities for budget allocation purposes is presented. This method, developed by a working group of the National Institute for Research on Cancer (IST), Genoa, Italy, is based on the partitioning of categories of the Science Citation Index and Journal Citation Reports (SCI-JCR) into deciles, which normalize...
BACKGROUND There is considerable expertise in the obesity field in identifying, appraising, and synthesising evidence to develop guidelines and recommendations for policy and practice. The recommendations, while based on evidence, are not formulated in a way that readily leads to implementation. This paper analyses the recent UK recommendations on obesity using a proposed implementation framewo...
Background and Aim: FRBR is one of the models considered in cataloging and work-to-work relationships are introduced as types of bibliographic relationships present in this model. This study examines the distribution of dispersion relationships in medical subject areas based on FRBR model in Persian medical sources published from 2006 to 2010. Materials and Methods: This study is a descriptive ...
In a bibliographic database, the main task is not to find exact duplicate records, rather it is to find those that refer to the same work but differ in some manner. Differences are typically due to inaccurate or inconsistent data entry. One such detection method was developed by Ridley [Ridley 92] who adopted a two stage technique. First, all records in a database were assigned a number generat...
Nowadays, most business, administration, and/or scientific databases contain both structured attributes and text attributes. We call a database that consists of both multidimensional structured data and narrative text data as multidimensional text database. Searching, OLAP, and mining such databases pose many research challenges. To enhance the power of data analysis, interesting entities and r...
Introduction The goal of this article is to introduce the most important of the different molecular biology databases available to researchers. Recent advances in technology have resulted in an information explosion. This has risen the challenge of providing an integrated access method to these data, capable of querying cross-referenced but highly heterogeneous databases. The SRS (Etzold, Ulyan...
Medical Ethics is a branch of science that has received attention due to developments in medical treatments and technology as well as complex social transformations and involvement of social sciences, law and so on in medicine. The present paper attempted to perform an analysis and historiography of scientific publications in the field of medical ethics and their growth and development rate bet...
Information on the preparation and characterization of heavy-atom derivatives of protein crystals has been collected, either from the literature or directly from protein crystallographers, and assembled in the form of a heavy-atom data bank (HAD). The data bank contains coordinate data for the heavy-atom positions in a form that is compatible with the crystallographic data in the Brookhaven Pro...
Marine protist diversity inventories have largely focused on planktonic environments, while benthic protists have received relatively little attention. We therefore hypothesize that current diversity surveys have only skimmed the surface of protist diversity in marine sediments, which may harbor greater diversity than planktonic environments. We tested this by analyzing sequences of the hyperva...
BACKGROUND In Panama, the health research system has been strengthened during recent years by the development of new financing opportunities, promotion of scientific and technological activities, and initiation of human capital training to ultimately improve competitiveness. However, aligning this system with the population's health needs is a significant challenge. This study was designed to c...
