In hospitals and clinics, anyone who “touches” a patient has a license authorizing them to do so—from the phlebotomist to the cardiologist, from the genetic counselor to the social worker, and so on, except for the clinical medical librarian. This column discusses the intent versus the realities of occupational licensure for clinical medical librarians and provides recommendations for next steps. 相似文献

Relying on cultural transmission, social identity and self-categorization theories, this study uses an innovative two-part photo-pasting and survey method to investigate quantitatively and qualitatively non-fans’, fans’ and players’ assumptions about what positions black and white players should occupy in American football. Both white and black players and fans showed evidence of being cultural transmitters of racial ideologies associated with the quarterback position in American football. Overall, the respondent choices for quarterback diverged significantly from equality but not significantly from the reality of the National Football League. Players and fan and non-fan participants alike showed evidence of being cultural consumers and transmitters of racial ideologies associated with the quarterback position. Narrative reasons for player choices aligned with past literature about racial stereotypes. On most measures, the findings did not differ greatly among the institutions from which study participants were drawn, their diversity in geography, racial composition, ideology, athletic division and public–private status notwithstanding. 相似文献

A theoretical model of nonscience majors' motivation to learn science was tested by surveying 369 students in a large‐enrollment college science course that satisfies a core curriculum requirement. Based on a social‐cognitive framework, motivation to learn science was conceptualized as having both cognitive and affective influences that foster science achievement. Structural equation modeling was used to examine the hypothesized relationships among the variables. The students' motivation, as measured by the Science Motivation Questionnaire (SMQ), had a strong direct influence on their achievement, as measured by their science grade point average. The students' motivation was influenced by their belief in the relevance of science to their careers. This belief was slightly stronger in women than men. Essays by the students and interviews with them provided insight into their motivation. The model suggests that instructors should strategically connect science concepts to the careers of nonscience majors through such means as case studies to increase motivation and achievement. © 2006 Wiley Periodicals, Inc.

This investigation assessed the effect of dietary nitrate (NO3?) supplementation, in the form of beetroot juice (BR), on repeat-sprint performance in normoxia and normobaric hypoxia. 12 male team-sport athletes (age 22.3 ± 2.6 y, VO2peak 53.1 ± 8.7 mL.kg?1.min?1) completed three exercise trials involving a 10 min submaximal warm-up and 4 sets of cycling repeat-sprint efforts (RSE; 9 × 4 s) at sea level (CON), or at 3000 m simulated altitude following acute supplementation (140 mL) with BR (HYPBR; 13 mmol NO3?) or NO3–depleted BR placebo (HYPPLA). Peak (PPO) and mean (MPO) power output, plus work decrement were recorded during the RSE task, while oxygen consumption (VO2) was measured during the warm-up. There were no significant differences observed between HYPBR and HYPPLA for PPO or MPO; however, work decrement was reduced in the first RSE set in HYPBR compared with HYPPLA. There was a moderate effect for VO2 to be lower following BR at the end of the 10 min warm-up (ES = 0.50 ± 0.51). Dietary NO3? may not improve repeat-sprint performance in hypoxia but may reduce VO2 during submaximal exercise. Therefore, BR supplementation may be more effective for performance improvement during predominantly aerobic exercise. 相似文献

The forward skating start is a fundamental skill for male and female ice hockey players. However, performance differences by athlete’s sex cannot be fully explained by physiological variables; hence, other factors such as skating technique warrant examination. Therefore, the purpose of this study was to evaluate the body movement kinematics of ice hockey skating starts between elite male and female ice hockey participants. Male (n = 9) and female (n = 10) elite ice hockey players performed five forward skating start accelerations. An 18-camera motion capture system placed on the arena ice surface captured full-body kinematics during the first seven skating start steps within 15 meters. Males’ maximum skating speeds were greater than females. Skating technique sex differences were noted: in particular, females presented ~10° lower hip abduction throughout skating stance as well as ~10° greater knee extension at initial ice stance contact, conspicuously followed by a brief cessation in knee extension at the moment of ice contact, not evident in male skaters. Further study is warranted to explain why these skating technique differences exist in relation to factors such as differences in training, equipment, performance level, and anthropometrics. 相似文献

When continuous development becomes the norm on the social web, finding a way to put forward new development ideas to your audience and get their feedback at an early stage is the natural result. This article discusses how one major medical journal created a ‘beta’ site to support new online development and gather user feedback, speeding development initiatives and creating intrinsic value in the experimental environment. The goals of the site, organization of the teams, and practical and brand benefits are discussed. 相似文献
