Definitions of a “document”

Although the definition of a document has been the subject of a vast number of works, analysis of the latest publications shows that the question remains controversial. In this article the two definitions of “document” accepted as the broadest ones, i.e., the principal and conventional ones, are taken for examination. The principal definition of a document starts from the document as a part in the social information-communication process, therefore, having its place in it and performing a function that is major, and obligatory for the document. The conventional definition limits the scope of this concept, mostly in terms of material and characters, with allowance for specific features in the operation of documental communication systems.     

A web of science databases as a criterion for assessment of the research activities of Belarusian scientists

The publication activity of the scientists of the National Academy of Sciences of Belarus, the degree of reflection of their papers in Web of Science databases, and the data on the citation of Belarusian researchers in the studies of other scientists are discussed.     

Investigation of the flow of scientific-technical information on the basis of the Russian technical literature on nanostructures and nanotechnologies

The objective of this investigation of the Russian technical literature on nanostructures and nanotechnologies is a study of the dynamics and the cumulative number of publications (CPN) concerning nanostructures and nanotechnologies, the dynamics an2 CPN for different types of publications, the publication productivity of Russian scientists and Russian cities concerning nanostructures and nanotechnologies, the scientific activity of Russian scientific-research and educational institutions concerning nanostructures and nanotechnologies, the investigation of Russian periodicals and continuing publications concerning nanostructures and nanotechnologies, and the simulation of the CPN and prediction of the CPN for nanostructures and nanotechnologies.     

Submaximal exercise and maturation in 12-year-olds

The aim of this study was to examine the maturation responses of young people to submaximal treadmill exercise. Body mass was controlled using both the conventional ratio standard and allometric modelling. Ninety-seven boys and 97 girls with a mean age of 12.2 years completed a discontinuous, incremental exercise test to voluntary exhaustion. We measured peak oxygen uptake (VO2peak) and VO2 when running at 8, 9 and 10 km x h(-1). Sexual maturation was assessed visually using Tanner's indices of pubic hair. Peak VO2 was significantly higher in boys (P<0.001); this was still the case when the influence of body mass was covaried out. During submaximal exercise, no significant differences in absolute VO2 were observed between the sexes (P>0.05); however, values of VO2, expressed both in ratio with body mass and adjusted for body mass using allometry, were significantly greater in boys than in girls (P<0.001). For absolute VO2, significant main effects (P<0.05) were seen for maturity at each exercise stage. With the influence of body mass controlled using either the ratio standard or allometry, no significant main effects (P>0.05) for maturity were observed. Our results indicate that boys are less economical than girls while running at 8-10 km x h(-1) and that, independently of body mass, maturation does not influence the VO2 response to submaximal exercise.     

GaIN (Georgia Interactive Network for Medical Information) study on health professionals' search requests and continuing education needs

Health sciences librarians are being called upon to be more proactive in their institutions' continuing education efforts. In an effort to identify whether search requests indicated CE needs, a study was conducted by a group of members of GaIN (Georgia Interactive Network for Medical Information). MEDLINE requests from health care professionals for subject specific clinical topics were collected during a six-month period via a standard search request form created for the study. Copies of all completed requests were collected and broad ICD-9 codes assigned to the search topics. Institutional reports were generated for each participating library to share with hospital CE coordinators. They were also compiled for the group as a whole, and reflected the "hottest" topics requested during the study period for physicians and for non-physicians (nurses, allied health, administrators). A survey to hospital librarians and CE educators showed some value in the reports, but greater potential for further collaboration between librarians and CE coordinators.     

Age and sex differences in motor performance of pre-school Nigerian children

Differences in motor performance according to chronological age and gender of 341 young Nigerian children (ages 3 to 5) were examined. Motor test items designed by Morris et al. (1981) were administered to the subjects. Analysis of variance was used to determine significant differences in the motor performance of the groups. In the whole sample, more age differences than sex differences in performance were noted. Except for the balancing and running performances of the girls, a fairly linear trend of improvement with age was observed in the motor performances of the groups. At each age level the boys consistently performed better than the girls in four of the six motor tests (catching, standing long jump, tennis ball throw and speed run). Generally, the 4- and 5-year-old children performed homogeneously, with a great disparity in performance noted for the 3-year-old children. The results of this study confirm that age and sex differences in motor performance occur at early childhood. Prospective studies should seek to control the extraneous factors which influence motor development and account for the observed differences in motor performance of pre-school children.     

IAIMS and the library at the University of Utah

The formal creation of an Integrated Academic Information Management System (IAIMS) at the University of Utah began in the fall of 1983. The keystone of the IAIMS effort is the HELP hospital information system. IAIMS at the University of Utah is a broad-based program extending across the Health Sciences Center and beyond to health professionals throughout the inter-mountain area. This paper describes the background that led to IAIMS, the IAIMS planning process, and the library's participation in this effort.
