James 《Government Information Quarterly》2005,22(4):644-662
Somewhere in the vicinity of 80 percent of all governmental information has some “geographic” element, and the vast majority is called “geospatial” because of the nature of describing spatial phenomena of the earth. Geospatial information has been increasing steadily in popularity and use since the advent of geographic information systems in the 1960s. From the early 1990s until the present, research libraries have seen an increase in the availability of geospatial information, and they have also seen a substantial change in the services provided to support the needs of clients seeking that information. However, recent events have altered the “access landscape.” September 11, 2001, and subsequent events, caused many policy shifts to take place as to how, or whether, access to governmental geospatial information should be granted. This paper explores those policy developments with the goal of prognosticating on the future of access to governmental geospatial information. 相似文献

Why is there an increased need for quantitative indicators of student socioeconomic status at the school level? What alternative approaches have been used to measure SES? Can principals accurately estimate the SES distribution of their student populations? How do their estimates correlate with other indexes o f family SES? 相似文献

James M. Heffernan Ph.D. 《Innovative Higher Education》1977,1(2):111-123
This paper describes a fast-growing variety of programs that directly enable adult learners to pursue educational and career plans within their communities. Educational brokering serves an intermediary role between individual clients and the vast array of educational resources in a region. This paper considers the missions of brokering—advisement, assessment, and advocacy—its organizational arrangements, and the sources of its support and development. Specific successes and impacts of brokering are presented, as is the importance of the brokering idea to several larger public policy issues. Efforts currently underway to expand brokering activities on a national level are also discussed.Dr. Heffernan is an Assistant Professor in the Department of Higher/Postsecondary Education at Syracuse University and is Coordinator of Research and Editor of theBulletin of the National Center for Educational Brokering. He has been assisted in the preparation of this article by Francis U. Macy and Donn F. Vickers, Director and Associate Director, respectively, of the National Center for Educational Brokering, 405 Oak Street, Syracuse, New York 13203. 相似文献

Current findings from research on structured abstracts. 总被引:5,自引:0,他引:5
James Hartley 《Journal of the Medical Library Association》2004,92(3):368-371
BACKGROUND: Structured abstracts were introduced into medical research journals in the mid 1980s. Since then they have been widely used in this and other contexts. AIM: The aim of this paper is to summarize the main findings from research on structured abstracts and to discuss the limitations of some aspects of this research. METHOD: A narrative literature review of all of the relevant papers known to the author was conducted. RESULTS: Structured abstracts are typically longer than traditional ones, but they are also judged to be more informative and accessible. Authors and readers also judge them to be more useful than traditional abstracts. However, not all studies use "real-life" published examples from different authors in their work, and more work needs to be done in some cases. CONCLUSIONS: The findings generally support the notion that structured abstracts can be profitably introduced into research journals. Some arguments for this, however, have more research support than others. 相似文献

We examined the intersection of students' understanding and acceptance of evolution and their epistemological beliefs and cognitive dispositions. Based on previous research, we hypothesized there would be a relation between understanding and acceptance. We also hypothesized that students who viewed knowledge as changing and who have a disposition toward open‐minded thinking would be more likely to accept the scientific explanation of human evolution, and that beliefs and dispositions would not be related to acceptance of a topic that is generally perceived as noncontroversial. Ninety‐three undergraduate students enrolled in a nonmajors biology class completed measures of their (a) content knowledge of evolution and photosynthesis and respiration; (b) acceptance of theories of animal evolution, human evolution, and photosynthesis; and (c) epistemological beliefs and cognitive dispositions. Although our findings did reveal a significant relation between knowledge and reported acceptance for photosynthesis, there was no relation between knowledge and acceptance of animal or human evolution. Epistemological beliefs were related to acceptance, but only to the acceptance of human evolution. There was no relation between students' epistemological beliefs and their general acceptance of animal evolution or photosynthesis. Three subscales, Ambiguous Information, Actively Open‐Minded Thinking, and Belief Identification, were significantly correlated with understanding evolutionary theory. We argue these findings underscore the importance of intentional level constructs, such as epistemological beliefs and cognitive dispositions, in the learning of potentially controversial topics. © 2003 Wiley Periodicals, Inc.

Reciprocal Negative Affect in Parent-Child Interactions and Children's Peer Competency 总被引:6,自引:0,他引:6
The relationship between preschool children's peer competency and the exchange of reciprocal negative affect displays during physical play with parents was examined. Teacher ratings of children's peer competency were obtained from children's preschools. Parents and children (41 families) were observed during a physical play paradigm called "the hand game" which permitted physically stimulating play, yet which also permitted clear recording of participants' facial expressions. Interactions were coded second by second for 8 min using a system of 12 mutually exclusive and exhaustive codes to categorize the affect displayed by participants. Fathers who typically responded to their children's negative affect displays with negative affect of their own had children who shared less, were more aggressive, and avoided others. Implications of the findings for theories of family-peer relationships are discussed. 相似文献

Artificial rugby union playing surface installation is increasing. This prospective cohort study aimed to examine the effect of playing surface on match injury types within 157 players of two UK professional rugby union clubs playing 209 matches (96 on artificial surfaces and 113 on grass) over three seasons. There was no difference in overall injury risk between the two playing surfaces with injury incidence on artificial 80.2 (CI 69.9–91.7) and on grass 81.9 per 1000 match-hours (CI 72.2–92.5), with an incidence rate ratio (RR) of 0.98 (CI 0.82–1.17). There was a higher rate of concussion (RR 0.52, CI 0.34 – 0.78) and chest injuries on grass (RR 0.26 CI 0.07, 0.95), and a higher rate of thigh haematoma (RR 2.25, CI 1.05–4.82) foot injuries (RR 4.12, CI 1.10, 15.40) and injury to players being tackled (RR 1.46, CI 1.00, 2.15) on artificial. Whilst there was no higher injury risk for matches played on artificial versus natural grass surfaces, the higher incidence of concussion and chest injury on grass, and the higher rate of foot injuries on artificial surfaces may be related to tackle and footwear-to-surface interface factors. 相似文献
