Quality markers and use of electronic journals in an academic health sciences library.     

Judith L Wulff  Neal D Nixon 《Journal of the Medical Library Association》2004,92(3):315-322

OBJECTIVES: Patterns of use of electronic versions of journals supplied by an academic health sciences library were examined to determine whether they differed from patterns of use among corresponding print titles and to relate the applicability of print collection development practices to an electronic environment. METHODS: Use data supplied by three major vendors of electronic journals were compared to reshelving data for corresponding print titles, impact factors, and presence on Brandon/Hill Lists. RESULTS: In collections where one-click access from a database record to the full text of articles was possible, electronic use correlated with print use across journal pairs. In both versions, Brandon/Hill titles were used more frequently than non-Brandon/Hill titles, use had modest correlations with journals' impact factors, and clinical use appeared to be higher than research use. Titles that had not been selected for the library's print collections, but which were bundled into publishers' packages, received little use compared to electronic titles also selected in print. CONCLUSIONS: Collection development practices based on quality and user needs can be applied with confidence to the electronic environment. Facilitating direct connections between citation databases and the corresponding journal articles regardless of platform or publisher will support scholarship and quality health care.  相似文献   

THE EFFECT OF SENIOR AUDITORS ON COLLEGE CLASSES: AN ASSESSMENT BY FACULTY MEMBERS     

William C. Hays  Judith A. Hays 《Educational gerontology》2013,39(7):693-709

College and university programs that permit older persons to audit regularly scheduled classes free of charge through tuition waiver programs are open to those aged 60 and over or 65 and over in at least 44 states. A study of such a program at a medium‐sized state university included a survey of 135 faculty members teaching classes audited by elder students. Seventy‐four percent of faculty members surveyed returned a one‐page survey questionnaire that asked them to describe the behavior of older auditors and compare them to younger students. Findings indicate that senior auditors are conscientious, most attending classes regularly and some completing written assignments and taking tests. Faculty members indicated that older auditors make a positive difference in class, learn as quickly as younger students, and are more motivated than younger students. Ninety percent of faculty respondents felt that the free audit program offers older students something of value. No significant differences in responses were found when controlling for the teaching experience of faculty members, for their age, or for the number of older students who had audited their classes.  相似文献

Investigation of toppling ball flight in American football with a mechanical field-goal kicker     

Chase M. Pfeifer  Timothy J. Gay  Jeff A. Hawks  Shane M. Farritor  Judith M. Burnfield 《Sports Engineering》2018,21(2):95-102

A mechanical field-goal kicking machine was used to investigate toppling ball flight in American football place-kicking, eliminating a number of uncontrollable impact variables present with a human kicker. Ball flight trajectories were recorded using a triangulation-based projectile tracking system to account for the football’s 3-dimensional position during flight as well as initial launch conditions. The football flights were described using kinematic equations relating to projectile motion including stagnant air drag and were compared to measured trajectories as well as projectile motion equations that exclude stagnant air drag. Measured football flight range deviations from the non-drag equations of projectile motion corresponded to deficits between 9 and 31%, which is described by a football toppling compound drag coefficient of 0.007 ± 0.003 kg/m. Independent variables including impact location and impact angle orientation resulted in 15 impact conditions. We found that an impact location of 5.5 cm from the bottom of the ball maximized trajectory height and distance. At the 5.5-cm impact location, alterations in impact angle produced minimal change in football trajectory, including launch angle (range = 1.96 deg), launch speed (range = 1.06 m/s), and range (range = 0.94 m).  相似文献   

Physiological characteristics of successful mountain bikers and professional road cyclists     

Lee H  Martin DT  Anson JM  Grundy D  Hahn AG 《Journal of sports sciences》2002,20(12):1001-1008

The aims of this study were to compare the physiological and anthropometric characteristics of successful mountain bikers and professional road cyclists and to re-examine the power-to-weight characteristics of internationally competitive mountain bikers. Internationally competitive cyclists (seven mountain bikers and seven road cyclists) completed the following tests: anthropometric measurements, an incremental cycle ergometer test and a 30 min laboratory time-trial. The mountain bikers were lighter (65.3+/-6.5 vs 74.7+/-3.8 kg, P= 0.01; mean +/- s) and leaner than the road cyclists (sum of seven skinfolds: 33.9+/-5.7 vs 44.5+/-10.8 mm, P = 0.04). The mountain bikers produced higher power outputs relative to body mass at maximal exercise (6.3+/-0.5 vs 5.8+/-0.3 W x kg(-1), P= 0.03), at the lactate threshold (5.2+/-0.6 vs 4.7+/-0.3 W x kg(-1), P= 0.048) and during the 30 min time-trial (5.5+/-0.5 vs 4.9+/-0.3 W x kg(-1), P = 0.02). Similarly, peak oxygen uptake relative tobody mass was higher in the mountain bikers (78.3+/-4.4 vs 73.0+/-3.4 ml x kg(-1) x min(-1), P = 0.03). The results indicate that high power-to-weight characteristics are important for success in mountain biking. The mountain bikers possessed similar anthropometric and physiological characteristics to previously studied road cycling uphill specialists.  相似文献   

Child care research: an editorial perspective     

Langlois JH  Liben LS 《Child development》2003,74(4):969-975

The goals of Child Development's new From Another Perspective format are discussed, and an overview of the content of the inaugural From Another Perspective collection on child care effects is provided. The two lead articles suggest, respectively, that long hours in child care are related to children's later behavior problems and that child care may be physiologically challenging for young children. Commentaries focus on the need to examine a range of additional factors before drawing definitive conclusions about cause and effect. Among the issues discussed in the commentaries are the need to account for context, individual differences among children, and methodological challenges. The introductory editorial also overviews policy implications and directions for future research.  相似文献

A Systemic Change Model for Leadership, Inclusion, and Mentoring (SLIM)     

Judith Fleming  Maria Love 《Early Childhood Education Journal》2003,31(1):53-57

The Systemic Change Model for Leadership, Inclusion, and Mentoring (SLIM) concentrates on systemic changes occurring in child care organizations where the director builds caring, consistent relationships with the total system and empowers the staff and others through leadership. The model recognizes the importance of focusing on system changes by the organization's director. Leadership qualities related to concepts used in business organizations are included in the training. A mentoring program will help the director focus on his or her leadership capabilities in moving the organization to change. An important collaboration component of the model is working with inclusion of children with special needs. Included in the model are: collaboration components, systemic change, director leadership role, business model related to child care, mentoring, and inclusion of children with special needs.  相似文献
