Column Editor's Note. This column focuses on formal collaboration and networking among libraries through consortia. It offers in-depth examinations of issues facing modern library consortia including (but not limited to) e-resource licensing, ebooks, next generation integrated library systems, shared print archiving, shared digital repositories, governance and other relevant topics. Contributions are accepted for this column and must be submitted to George Machovec (george@coalliance.org). Contact the column editor for suggested topics, deadlines and formatting.
ConnectNY has been involved in consortial e-book projects since 2010. Based upon the experience of these group e-book projects, we will explore different methods for assuming the shared cost of group e-book programs and then describe ways in which DDA programs may promote a positive Return on Investment (ROI) for groups as compared to individual institutions. We will argue that while use is a factor that can be taken into account when distributing cost amongst members, a budget-based percentage approach will allow consortia to effectively initiate and manage such projects over time. 相似文献

Co-workers are an important source of information in organizations. Consequently, information managers seek to facilitate the use of such human information sources. Although various studies about what influences the use of human information sources in organizations exist, it is difficult for information managers to utilize insights from this research body. The studies have provided contradictory results regarding the role of accessibility and quality and suffer from various weaknesses. To address these weaknesses, several studies are employing other research methods. This study aims to contribute to the methodological development of this emerging new line of research by exploring the value of a think aloud approach to such studies. In addition, it aims to provide more insight into the role of accessibility and quality in the selection of human information sources in organizations. Fifty-six employees from four governmental organizations were asked to think aloud while selecting human information sources. The findings of this study corroborate those of studies taking a similar approach: source quality is the most dominant factor in the selection of human information sources. The think aloud approach seems a valuable contribution to available research methods to assess the role of accessibility and quality in human source selection in organizations. 相似文献

This paper uses a database on scientific interaction in the field of the economics of technological change and innovation. The database is used to address two issues. First, the network is shown to be (approximately) scale-free. This suggests that growth of the number of scholars active in the field and so-called preferential attachment (i.e., scholars entering the field prefer to attach themselves to highly reputable existing members of the network) are characteristic of the nature of the underlying field. Thus, increasing returns seem to govern mechanisms of reputation formation. Second, the potential existence of cohesive subgroups of relatively strongly connected scholars is explored, and the implications of this for the paradigmatic structure of the field are discussed. 相似文献

Subject searches in the National Library of Poland catalog are still comprised of a significant number of all searches, but understanding and exploration of the National Library of Poland Subject Headings causes many problems, not only for the end-users, but also for many librarians. Another problem in the National Library of Poland is the insufficient use of relationships between the terms. The solution could be a properly designed Web application based on a topic map using appropriate visualization that supports indexing and information retrieval in the National Library of Poland. The article presents the main stages of a planned project. 相似文献

Our tendency is to generate ever-increasing amounts of information to deal with the uncertainties we face in today's turbulent environment. However, if we look at the problem more fundamentally, we see that uncertainty, the variable responsible for information demand, itself can be reduced. Thus, we should not get fixated on information generation (the supply-side approach) but should also consider ways of reducing needs for information flows (the demand-side approach). This article provides an overview of a Dutch sociotechnical approach that focuses on reduction of complexity so as to reduce uncertainty and thereby organizational information flows. 相似文献

Abstract The purpose of this study was to evaluate the effects of a realistic, feasible, and commonly used fitness training programme on cardiac autonomic control in 14 sedentary men aged 62.0 ± 6.1 years (mean ± s). All participants performed a one-year fitness training programme in which training intensity and frequency were specifically chosen to be compliant for the majority of the participants (2 – 3 sessions per week at moderate intensity). At the same time, a reference group consisting of 15 sedentary age-matched men (age 64.2 ± 6.5 years) did not change their habitual physical activity. Measurements were performed before and after the training intervention. Cardiac autonomic control was inferred from resting values (supine and standing) of heart rate variability (HRV) computed in the frequency domain over 10-min intervals. Endurance capacity was evaluated during a maximal incremental bicycle ergometer test. In spite of an increase in peak oxygen consumption ([Vdot]O2peak) by 6.4% after training, heart rate in the training group remained unchanged at rest and at the same metabolic demand. No changes in resting parameters of HRV were shown for either groups or positions. Results from this study provide no evidence of a clinically meaningful increase in the vagal modulation to the sinus node at rest after one year of low-volume and moderate-intensity fitness training in men aged 55 – 75 years. 相似文献

Abstract The objective of this study was to analyse the correctness of the offside judgements of the assistant referees during the final round of the FIFA 2002 World Cup. We also contrasted two hypotheses to explain the errors in judging offside. The optical error hypothesis is based on an incorrect viewing angle, while the flash-lag hypothesis refers to perceptual errors associated with the flash-lag effect (i.e. a moving object is perceived as spatially leading its real position at a discrete instant signalled by a briefly flashed stimulus). Across all 64 matches, 337 offsides were analysed using digital video technology. The error percentage was 26.2%. During the first 15 min match period, there were significantly more errors (38.5%) than during any other 15 min interval. As predicted by the flash-lag effect, we observed many more flag errors (86.6%) than non-flag errors (13.4%). Unlike the predictions of the optical error hypothesis, there was no significant difference between the correct and incorrect decisions in terms of the positioning of the assistant referees relative to the offside line (0.81 and 0.77 m ahead, respectively). To reduce the typical errors in judging offside, alternative ways need to be considered to teach assistant referees to better deal with flash-lag effects. 相似文献

During the 1997 Federation Internationale des Societes d'Aviron (FISA) World Junior Rowing Championships, the anthropometric characteristics of 245 female junior rowers aged 17.5 ± 0.8 years (mean ± s) were assessed. Twenty-seven body dimensions (body mass, 6 heights or lengths, 4 breadths, 10 girths and 6 skinfolds) were measured in total. The elite female junior rowers were taller (174.5 ± 6.2 cm) and heavier (69.5 ± 6.2 kg), with greater length, breadth and girth dimensions, but lower skinfold thicknesses than a representative sample of Flemish (Belgian) girls of the same chronological age. An anthropometric profile chart was constructed that was rowing-specific and norms were established. Compared with scullers, sweep rowers were heavier (+4.2 kg) and taller (+2.8 cm), with greater length, breadth (except for femur width) and girth dimensions (except for calf girth). Sweep rowers also had greater skinfold thicknesses (except for the thigh and calf skinfolds). Finalists were heavier (+3.6 kg) and taller (+3.9 cm), with greater length, breadth (except for femur width) and girth dimensions (except for calf girth) than non-finalists. No significant differences were found for skinfold thicknesses between finalists and non-finalists. 相似文献

Team‐based learning (TBL) is an instructional strategy that combines independent out‐of‐class preparation for in‐class discussion in small groups. This approach has been successfully adopted by a number of medical educators. This strategy allowed us to eliminate anatomy lectures and incorporate small‐group active learning. Although our strategy is a modified use of classical TBL, in the text, we use the standard terminology of TBL for simplicity. We have modified classical TBL to fit our curricular needs and approach. Anatomy lectures were replaced with TBL activities that required pre‐class reading of assigned materials, an individual self‐assessment quiz, discussion of learning issues derived from the reading assignments, and then the group retaking the same quiz for discussion and deeper learning. Students' performances and their educational experiences in the TBL format were compared with the traditional lecture approach. We offer several in‐house unit exams and a final comprehensive subject exam provided by the National Board of Medical Examiners. The students performed better in all exams following the TBL approach compared to traditional lecture‐based teaching. Students acknowledged that TBL encouraged them to study regularly, allowed them to actively teach and learn from peers, and this served to improve their own exam performances. We found that a TBL approach in teaching anatomy allowed us to create an active learning environment that helped to improve students' performances. Based on our experience, other preclinical courses are now piloting TBL. Anat Sci Ed 1:3–9, 2008. © 2007 American Association of Anatomists. 相似文献
