The benefits claimed for open access publishing in the medical area are subjected to evaluation and question. It is represented that these benefits are, in many cases, illusory or doubtful.  相似文献

This article is the fourth in a series on New Directions. The National Health Service is under pressure, challenged to meet the needs of an ageing population, whilst striving to improve standards and ensure decision making is underpinned by evidence. Health Education England is steering a new course for NHS library and knowledge services in England to ensure access to knowledge and evidence for all decision makers. Knowledge for Healthcare calls for service transformation, role redesign, greater coordination and collaboration. To meet user expectations, health libraries must achieve sustainable, affordable access to digital content. Traditional tasks will progressively become mechanised. Alongside supporting learners, NHS librarians and knowledge specialists will take a greater role as knowledge brokers, delivering business critical services. They will support the NHS workforce to signpost patients and the public to high‐quality information. There is a need for greater efficiency and effectiveness through greater co‐operation and service mergers. Evaluation of service quality will focus more on outcomes, less on counting. These changes require an agile workforce, fit for the future. There is a bright future in which librarians’ expertise is used to mobilise evidence, manage and share knowledge, support patients, carers and families, optimise technology and social media and provide a keystone for improved patient care and safety.  相似文献

A bibliography of periodicals focused on planning within the urban studies field is presented. The bibliography contains scholarly, trade, and popular titles. Each entry contains identical categories of information (where each category is applicable), including an annotation. The bibliography is meant to aid in collection development in this subject area.  相似文献

Lumbar-pelvic kinematics change in response to increasing rowing stroke rates, but little is known about the effect of incremental stroke rates on changes in joint kinetics and their implications for injury. The purpose of this study was to quantify the effects of incremental rowing intensities on lower limb and lumbar-pelvic kinetics. Twelve female rowers performed an incremental test on a rowing ergometer. Kinematic data of rowers’ ankle, knee, hip and lumbar-pelvic joints, as well as external forces at the handle, seat and foot-stretchers of the rowing machine were recorded. Inter-segmental moments and forces were calculated using inverse dynamics and were compared across stroke rates using repeated measures ANOVA. Rowers exhibited increases in peak ankle and L5/S1 extensor moments, reductions in peak knee moments and no change in peak hip moments, with respect to stroke rate. Large shear and compressive forces were seen at L5/S1 and increased with stroke rate (< 0.05). This coincided with increased levels of lumbar-pelvic flexion. High levels of lumbar-pelvic loading at higher stroke rates have implications with respect to injury and indicated that technique was declining, leading to increased lumbar-pelvic flexion. Such changes are not advantageous to performance and can potentially increase the risk of developing injuries.  相似文献

This study engages the question of where successful emerging (pretenure) scholars are most likely to publish their research. Spurred on by findings of a survey of leaders in the field of educational technology/instructional design and technology (ET/IDT) to determine the advisability of a rank‐ordered list of journals for the purposes of decision making about tenure and promotion, this document analysis presents the results of measuring the conventional wisdom against the actual practices of emerging scholars. Findings suggest that pretenure scholars publish in a wide variety of outlets including some, but not all of those identified in earlier surveys. While it is understood that the tenure decision is a complicated one—based on many criteria (eg, teaching, service, grantsmanship, etc), research and scholarship remain primary determinants. Therefore, these findings will be useful to emerging scholars and to those decision makers seeking direction regarding research outlets. The study is limited by a focus from an original survey conducted in 2003 to primarily North American scholars as participants, however, international considerations are included. The findings indicate that a list of journals for tenure decision making may not be advisable at this point in the development of the field of ET/IDT.  相似文献
