Knowledge management (KM), or the effective use of knowledge, has been practiced successfully by many business organizations. Individual libraries and librarians have periodically utilized KM. However, on a comprehensive scale, the library culture seems divided. This article examines the attitudes and practices of two distinct groups of specialized librarians and their relationship to the use of KM tools.  相似文献

When Off-Campus Means Virtual Campus: The Academic Library in Second Life   总被引:1,自引:0,他引:1  
ABSTRACT

This article discusses how a library's consistent policy of accessibility and foresight positioned itself to serve its students, faculty and staff in the virtual world of Second Life. Always ahead of the technological curve, this library has been the front-runner in providing services to distance learners via text messaging, “chat,” e-mail, and telephone services and via its laptop librarian project across the campus. It now is poised and ready to provide service in Second Life. Collaboration between the library and teaching faculty culminated in the creation, development, and furnishing of a library in Second Life, an environment that gives new meaning to “off-campus” learning. Without marketing, but as a visible presence, the Second Life library was able to attract both off-campus guests and affiliated students and faculty and even participated in campus-wide projects. This experiment has enjoyed the support of both the university and library administration.  相似文献

Abstract

This article focuses on the possibilities that information technology and mass media offer to learning environments of children and grown‐ups, and in what way they are different from the reality a decade ago, inside and outside school. It takes into consideration the norms valid in learning in schools, including the teachers’ role, and looks into how they coincide with or contradict the modern technological possibilities. In the rapid changes of society and values, the school should serve many ages, children and adults, which would require a greater variety of jobs than at present. Understanding the value of one's own language and culture does not come through isolation; it comes through learning about different societies and cultures, through considering, comparing and categorizing. The article discusses several practical examples from the recent experiences of Iceland.  相似文献

Trans-Pacific transport of enhanced ozone plumes has been mainly attributed to fossil fuel combustion in Asia in spring, but less attention has been paid to vegetation fires in Asia. Here we show that the El Niño-Southern Oscillation (ENSO)-modulated fires in Southeast Asia, rather than Asian fossil fuel plumes, dominate the interannual variability of springtime trans-Pacific transport of ozone across the entire North Pacific Ocean. During El Niño springs, the intensified fires from both the Indochinese Peninsula and Indonesia, together with large-scale circulation anomalies, result in enhanced ozone plumes that stretch over 15 000 km in both the lower-middle and upper troposphere. This enhancement is also observed in the in situ measurements of ozone concentration, with an almost 10% increase at Mauna Loa Observatory, Hawaii, a unique site to monitor the long-distance transport over the North Pacific. This study reports an unexpectedly strong influence of vegetation fires, linked with climate variability, on global tropospheric chemistry and proves once more how complex the interactions in the climate system are.  相似文献

This study was undertaken in order to evaluate the use of students as peer assessors, in collaboration with academic tutors, in the assessment of second-year viva examinations as part of a problem based learning occupational therapy curriculum. Data were collected from three consecutive cohorts of second-year students (N = 93), and an assessment was made of the reliability of the academic tutor marking, and the reliability of peer marking against the tutor marks. Results demonstrated that overall ratings of the viva examination performances given by the panel of assessors (two peer assessors and one academic tutor), were significantly correlated. On some occasions, such as the assessment of a borderline student, the ratings given were not as closely correlated. Some modifications of the examination process are suggested in order to optimise the reliability of the outcomes, but the study results lend support for the practice of peer assessment.  相似文献

This study investigated the effects of a mentally fatiguing test on physical tasks among elite cricketers. In a cross-over design, 10 elite male cricket players from a professional club performed a cricket run-two test, a Batak Lite reaction time test and a Yo-Yo-Intermittent Recovery Level 1 (Yo-Yo-IR1) test, providing a rating of perceived exertion (RPE) after completing a 30-min Stroop test (mental fatigue condition) or 30-min control condition. Perceived fatigue was assessed before and after the two conditions and motivation was measured before testing. There were post-treatment differences in the perception of mental fatigue (P < 0.001; d = ?7.82, 95% CIs = ?9.05–6.66; most likely). Cricket run-two (P = 0.002; d = ?0.51, 95% CIs = ?0.72–0.30; very likely), Yo-Yo-IR1 distance (P = 0.023; d = 0.39, 95% CIs = 0.14–0.64; likely) and RPE (P = 0.001; d = ?1.82, 95% CIs = ?2.49–1.14; most likely) were negatively affected by mental fatigue. The Batak Lite test was not affected (P = 0.137), yet a moderate (d = 0.41, 95% CIs = ?0.05–0.87) change was likely. Mental fatigue, induced by an app-based Stroop test, negatively affected cricket-relevant performance.  相似文献
