Not virtual,but a real,live, online,interactive reference service     

Jerant LL  Firestein K 《Medical reference services quarterly》2003,22(2):57-68

In today's fast-paced environment, traditional medical reference services alone are not adequate to meet users' information needs. Efforts to find new ways to provide comprehensive service to users, where and when needed, have often included the use of new and developing technologies. This paper describes the experience of an academic health science library in developing and providing an online, real-time reference service. Issues discussed include selecting software, training librarians, staffing the service, and considering the future of the service. Use statistics, question type analysis, and feedback from users of the service and librarians who staff the service, are also presented.  相似文献   

The influence of crank rate on peak oxygen consumption during arm crank ergometry   总被引：1，自引：0，他引：1  

Smith PM  Price MJ  Doherty M 《Journal of sports sciences》2001,19(12):955-960

The aim of this study was to assess the influence of three imposed crank rates on the attainment of peak oxygen consumption (VO2peak) and other physiological responses during incremental arm crank ergometry. Twenty physically active, although non-specifically trained, males volunteered for the study. They completed an exercise protocol using an electrically braked arm ergometer (Lode Angio, Groningen, Netherlands) at crank rates of 60, 70 and 80 rev x min(-1). The order of tests was randomized and they were separated by at least 2 days. Peak VO2 was significantly higher (P < 0.05) at 70 and 80 rev x min(-1) than at 60 rev x min(-1). Peak ventilation volume increased as a function of crank rate and was higher (P < 0.05) at 80 than at 60 rev x min(-1). Peak heart rate was higher (P < 0.05) at 70 and 80 rev x min(-1) than at 60 rev x min(-1). Furthermore, 70 and 80 rev x min(-1) resulted in an extended test time compared with 60 rev x min(-1). The greater physiological responses observed during the tests at the two faster crank rates might have been the result of a postponement of acute localized neuromuscular fatigue, allowing for more work to be completed. We recommend, therefore, that an imposed crank rate between 70 and 80 rev x min(-1) should be used to elicit VO2peak and other physiological responses in arm crank ergometry.  相似文献

Peer‐Mediated Instruction in Inclusive Secondary Social Studies Learning: Direct and Indirect Learning Effects     

Thomas E. Scruggs  Margo A. Mastropieri  Lisa Marshak 《Learning disabilities research & practice》2012,27(1):12-20

Ten inclusive middle school social studies classes, including 133 general education students, and 24 students with mild disabilities (21 with learning disabilities and 3 with emotional disabilities), were assigned at random to a traditional instruction condition, or an experimental condition involving classwide peer tutoring with specialized materials and parent training. After 18 weeks of instruction, posttest data revealed that students in the experimental condition gained significantly more than students in the traditional instruction condition. These effects were observed on content included in the tutoring intervention, as well as on related content that was taught but not included in the tutoring intervention. Results are discussed within the context of recent research on inclusive secondary content area instruction.  相似文献   

Applying Tablet‐Based Performance Support Application for Technicians’ Training at the Israeli Air Force: A Case Study     

Eran Gal PhD  Hagit Meishar‐tal PhD  Ronit Ben Non  Adar Ben‐Basat  Lisa Paikin 《Performance Improvement Quarterly》2017,30(2):121-136

Performance support systems are mechanisms enabling users) productivity while reducing training expenses as support is being delivered in real time, often eliminating the need for costly pre‐performance training. Mobile technologies have created new opportunities for improved performance support systems, especially for tasks performed outside the offi ce. This article describes the fi rst mobile learning and performance support initiative taken by the Israeli Air Force. The project included the development and eff ectiveness pilot study of a learning and performance support application delivered via tablet to helicopter engine technicians. The application provided support videos and illustrations of maintenance routines, thereby enabling learning and practicing at the same time. Pilot study results show high performance levels of application users compared to those applying traditional methods. Results also show that self‐effi cacy levels were not aff ected by the successful performance achieved when using the mobile performance support application. Plans to expand mobile support use are also described.  相似文献   

Who Studies Women's Studies?     

Marion Price  Mairead Owen 《Gender and education》1998,10(2):185-198

ABSTRACT This article reports the initial findings of a study of the cohort of students who entered Liverpool John Moores University, England, to study women's studies in the autumn of 1994, basing its focus on the survey carried out as soon as the students entered the University and the in-depth interviews carried out later in that semester. The work proceeded within the tradition of grounded theory research and endeavoured to avoid prepared hypotheses in order to allow the themes to emerge from the students' answers. From the initial findings, the very strong emphasis on the salience of the students' choice of women's studies and the experiential importance of identity as a concept was striking. The article debates the theoretical difficulties in the theorising of identity in relation to the empirical, existential project of the students.  相似文献

Wake up Information Literacy Instruction: Ideas for Student Engagement     

Lisa Campbell  Diana Matthews  Nance Lempinen-Leedy 《图书馆管理杂志》2015,55(7):577-586

In this article, three librarians from Santa Fe College, the community college winner of the 2015 ACRL Excellence in Academic Libraries Award, share their successful work in information literacy instruction. While the ACRL award is given for overall achievement, this article focuses upon their creative and varied approaches to instruction, incorporating a wide blend of strategies to reach students across the college. Beginning with targeted approaches to virtual instruction, including broad use of the flipped classroom model, and building in active learning techniques, the librarians at Santa Fe College have built an instruction program that could serve as a model to community college libraries across the country.  相似文献   

Physical activity patterns of ethnic children from low socio-economic environments within the UK

Many children fail to meet physical activity (PA) guidelines for health benefits. PA behaviours are complex and depend on numerous interrelated factors. The study aims to develop current understanding of how children from low Socio-economic environments within the UK use their surrounding built environments for PA by using advanced technology. The environment was assessed in 96 school children (7–9 years) using global positioning system (GPS) monitoring (Garmin Forerunner, 305). In a subsample of 46 children, the environment and PA were assessed using an integrated GPS and heart rate monitor. The percentage of time spent indoor, outdoor, in green and non-green environments along with time spent in moderate-to-vigorous PA (MVPA) in indoor and outdoor environments were assessed. A 2-by-2 repeated measures analysis of covariance, controlling for body mass index, BF%, assessed the environmental differences. The findings show that 42% of children from deprived wards of Coventry fail to meet PA guidelines, of which 43% was accumulated during school. Children engaged in more MVPA outdoor than indoor environments (P < 0.01) and a greater amount of time was spent in non-green environments (P < 0.01). Increased time outdoors was negatively associated with BF%. In conclusion, outdoor environments are important for health-enhancing PA and reducing fatness in deprived and ethnic children.  相似文献
