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. 相似文献

Information asymmetry and information sharing 总被引:1,自引:0,他引:1
Gavin Clarkson Trond E. Jacobsen Archer L. Batcheller 《Government Information Quarterly》2007,24(4):827
Although much digital divide research focuses on access to technology, another cause of the divide is the lack of information awareness that we call information asymmetry. Information asymmetry often stems from inadequate information sharing and can result in negative consequences for both the information poor and the information rich. Information asymmetry has been insufficiently studied as a possible cause of underdevelopment and inequality. In response, we develop a typology to classify information asymmetry into two categories, horizontal and vertical, and then identify those information sharing practices that cause the imbalance. To illustrate the negative consequences of information asymmetry and the potential benefits of information sharing, we discuss two examples from the experiences of modern American Indian tribes. First, Indian tribes face horizontal information asymmetry when they attempt to access the capital markets, and second, they face vertical information asymmetry in terms of law enforcement data sharing. This article also describes our ongoing examination of horizontal information sharing among tribes and vertical information sharing between tribes and others sovereigns in the American polity as possible solutions to the problems created by information asymmetry. These strategic responses are embodied in two information systems, the Tribal Financial Information Clearinghouse and an Intergovernmental Tracking System for sharing law enforcement data. We conclude with a discussion of how our typology can be more generally applied to other instances of information asymmetry. 相似文献

A recent landmark settlement between the National Collegiate Athletic Association (NCAA) and the U.S. Department of Justice addressed many crucial issues relating to the eligibility of high school students with learning disabilities (LD) and their participation in college freshman athletics. Although the changes agreed upon in the consent decree should have wide-ranging ramifications generally in favor of students with LD, the more subjective nature of these changes opens the door for inevitable inconsistencies, biases, and possible abuses. In addition, larger issues remain unresolved, including (a) the NCAA's denial that is covered by the Americans with Disabilities Act, (b) the inconclusive status of whether college athletics is a major life activity, (c) the NCAA acting as a de facto national school board without rigorous research for setting policy on an informed basis, and (d) the lack of serious initiative on the part of the NCAA to take on a more supportive role in educational reform. 相似文献

Project GRAD (Graduate Ready for Activity Daily) evaluates a university course to promote physical activity. In a randomized study, 338 university seniors participated in either an intervention or control course for academic credit, and posttest data were collected on 321. The control course was knowledge-oriented. The intervention course taught behavior change skills in weekly lectures and peer-led labs. Physical activity was assessed with 7-Day Physical Activity Recall interviews. The intervention had no significant effects on men. Among women, the intervention increased total physical activity during leisure, strengthening exercises, and flexibility exercise. This university course had the intended effects of promoting healthful patterns of physical activity among women, but no effects were observed on men, who were more active than women at baseline. 相似文献

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. 相似文献

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. 相似文献
