Background: A librarian consultation service was offered to 88 primary care clinicians during office hours. This included a streamlined evidence‐based process to answer questions in fewer than 20 min. This included a contact centre accessed through a Web‐based platform and using hand‐held devices and computers with Web access. Librarians were given technical training in evidence‐based medicine, including how to summarise evidence. Objectives: To describe the process and lessons learned from developing and operating a rapid response librarian consultation service for primary care clinicians. Methods: Evaluation included librarian interviews and a clinician exit satisfaction survey. Results: Clinicians were positive about its impact on their clinical practice and decision making. The project revealed some important ‘lessons learned’ in the clinical use of hand‐held devices, knowledge translation and training for clinicians and librarians. Conclusions: The Just‐in‐Time Librarian Consultation Service showed that it was possible to provide evidence‐based answers to clinical questions in 15 min or less. The project overcame a number of barriers using innovative solutions. There are many opportunities to build on this experience for future joint projects of librarians and healthcare providers.  相似文献

This study used accelerometer and self-report measures of overall sedentary time (ST) and screen time behaviours to examine their respective associations with adiposity among UK youth. Participants (Year groups 5, 8, and 10; n=292, 148 girls) wore the SenseWear Armband Mini accelerometer for eight days and completed the Youth Activity Profile, an online report tool designed to estimate physical activity and ST.Stature, body mass and waist circumference were measured to classify adiposity outcomes (overweight/obese and central obesity). One-way between groups ANOVA and adjusted linear, logistic and multinomial logistic regression analyses were conducted. There was a significant main effect of age on total ST across the whole week (F(2, 289)=41.64, p≤0.001). ST increased monotonically across Year 5 (581.09±107.81 min·dˉ¹), 8 (671.96±112.59 min·dˉ¹) and 10 (725.80±115.20 min·dˉ¹), and all pairwise comparisons were significant at p≤0.001. A steep age-related gradient to mobile phone use was present (p≤0.001). ST was positively associated with adiposity outcomes independent of moderate-to-vigorous intensity physical activity (MVPA; p≤0.001). Engaging in >3 hours of video gaming daily was positively associated with central obesity (OR=2.12, p≤0.05) but not after adjustment for MVPA. Results further demonstrate the importance of reducing overall ST to maintain healthy weight status among UK youth.  相似文献   

Effects of consecutive days of match play on technical performance in tennis     

Danielle T. Gescheit  Rob Duffield  Melissa Skein  Neil Brydon  Stuart J. Cormack  Machar Reid 《Journal of sports sciences》2017,35(20):1988-1994

Elite tennis is characterised by repeated bouts of up to 5-set match play, yet little is known about the technical requirements of shots played. This study therefore investigated technical performance changes over consecutive days of prolonged, simulated tennis match play. A total of 7 well-trained men tennis players performed 4 consecutive days of competitive 4-h match play. Matches were notated to determine between-day changes in groundstroke and serve performance, as well as point and match durations. Changes ≥75% likely to exceed the smallest important effect size (0.2) were considered meaningful and represented as effect size ± 90% confidence interval. Effective playing time reduced on days 3 and 4, alongside likely increases in “stretch” groundstrokes over the 4 days (mean effect size ± 90% confidence interval; 0.57 ± 0.38) and “stretch” backhand returns on days 2 and 3 (0.39 ± 0.54 and 0.67 ± 0.55). Relative unforced errors increased on day 4 (vs. day 2; 0.36 ± 0.22) and second-serve winning percentage reduced after day 1 (?0.47 ± 0.50). Further, a likely increase in emotional outbursts characterised day 3 (vs. day 2; 0.73 ± 0.57). Consecutive-day match play impairs hitting accuracy, stroke positioning and emotional responses; an understanding of which prepares players for elite-standard tennis tournament play.  相似文献   

A Sport Education Fitness Season’s Impact on Students’ Fitness Levels,Knowledge, and In-Class Physical Activity     

Jeffery Kurt Ward  Danielle D. Wadsworth  Shelby Foote  Sheri J. Brock  Nikki Hollett 《Research quarterly for exercise and sport》2017,88(3):346-351

Purpose: The purpose of this study was to determine the extent to which a sport education season of fitness could provide students with recommended levels of in-class moderate-to-vigorous physical activity (MVPA) while also increasing students’ fitness knowledge and fitness achievement. Method: One hundred and sixty-six 5th-grade students (76 boys, 90 girls) participated in a 20-lesson season called “CrossFit Challenge” during a 4-week period. The Progressive Aerobic Cardiovascular Endurance Run, push-ups, and curl-ups tests of the FITNESSGRAM® were used to assess fitness at pretest and posttest, while fitness knowledge was assessed through a validated, grade-appropriate test of health-related fitness knowledge (HRF). Physical activity was measured with Actigraph GT3X triaxial accelerometers. Results: Results indicated a significant time effect for all fitness tests and the knowledge test. Across the entire season, the students spent an average of 54.5% of lesson time engaged in MVPA, irrespective of the type of lesson (instruction, free practice, or competition). Conclusions: The results suggest that configuring the key principles of sport education within a unit of fitness is an efficient model for providing students with the opportunity to improve fitness skill and HRF knowledge while attaining recommended levels of MVPA.  相似文献   

Levels of social complexity and dimensions of peer experiences in youth sport   总被引：1，自引：0，他引：1  

Holt NL  Black DE  Tamminen KA  Fox KR  Mandigo JL 《运动与训练心理学杂志》2008,30(4):411-431

We assessed young adolescent female soccer players' perceptions of their peer group experiences. Data were collected via interviews with 34 girls from two youth soccer teams (M age = 13.0 years). Following inductive discovery analysis, data were subjected to an interpretive theoretical analysis guided by a model of peer experiences (Rubin, Bukowski, & Parker, 2006). Five categories of peer experiences were identified across three levels of social complexity. At the interaction level players integrated new members into the team and learned to interact with different types of people. At the relationship level players learned about managing peer conflict. At the group level a structure of leadership emerged and players learned to work together. Findings demonstrated interfaces between peer interactions, relationships, and group processes while also simplifying some apparently complex systems that characterized peer experiences on the teams studied.  相似文献   

Sustainable Innovations: Bringing Digital Media and Emerging Technologies to the Classroom     

Danielle Herro 《理论付诸实践》2015,54(2):117-127

Because traditional schools struggle to effectively understand, implement, and sustain digital learning initiatives, innovating with digital media in classrooms is a difficult endeavor. Practitioners need examples to better understand conditions necessary to move forward with digital media and learning (DML) in schools. This article provides examples and supports research proposing that context and culture matter when innovating in schools. Three classroom cases using Web 2.0, app development, and game design are discussed, offering educators a pathway to consider similar pedagogical and participatory approaches to foster learning. Classroom contexts, teachers' perspectives, district supports, technical requirements, and scalability are highlighted. The examples suggest innovative DML initiatives can flourish within schools when participants are mindful of context and when a participatory culture is supported (Jenkins, Clinton, Purushotma, Robison, & Weigel, 2006).  相似文献   

The influence of sport goggles on visual target detection in female intercollegiate athletes     

Danielle C. Kauffman  Joseph F. Clark 《Journal of sports sciences》2015,33(11):1117-1123

The aim of this study was to examine the effects of sport goggles on visual target detection in female intercollegiate athletes. Participants were randomly divided into three groups that varied in goggle use (G) or no goggle use (NG) over a total of three 1-min trials during a visual target detection task. The NG-NG-NG group did not wear goggles for any of the trials, whereas the NG-G-NG group wore goggles for the second trial only, and the G-NG-G group wore goggles for the first and third trials. The task consisted of illuminated targets arranged in five concentric rings from central to peripheral visual angles. The effects of sport goggles on response time to detect targets were most evident in the peripheral rings. Those who did not wear sport goggles showed improved performance from the first to second trials. This improvement was impaired, however, in those who wore sport goggles. Moreover, there was a reversal of the performance improvements achieved without goggles in those who wore goggles on the third trial. Together, these findings suggest the sport goggles not only impaired the expected initial performance but also impaired visual target detection after performance improvements were seen. These findings suggest sport goggles may impair detection of peripheral visual stimuli in athletes.  相似文献   

Prospective Elementary Teachers’ Analysis of Children’s Science Talk in an Undergraduate Physics Course     

Danielle B. Harlow  Lauren H. Swanson  Valerie K. Otero 《Journal of Science Teacher Education》2014,25(1):97-117

We investigated how prospective teachers used physics content knowledge when analyzing the talk of elementary children during special activities in an undergraduate physics content course designed for prospective teachers. We found that prospective teachers used content knowledge to reflect on their own learning and to identify students’ science ideas and restate these ideas in scientific terms. Based on this research, we inferred that analyzing children’s ideas through videos provides a meaningful context for applying conceptual physics knowledge in physics courses. Activities that are embedded within a disciplinary curriculum, such as those studied here, may help prospective teachers learn to use disciplinary knowledge in exactly the type of activity in which their content knowledge will be most useful: listening to and interpreting children’s science ideas.  相似文献   

Searching ClinicalTrials.gov and the International Clinical Trials Registry Platform to inform systematic reviews: what are the optimal search approaches?     

Julie M. Glanville  Steven Duffy  Rachael McCool  Danielle Varley 《Journal of the Medical Library Association》2014,102(3):177-183

Background:

Since 2005, International Committee of Medical Journal Editors (ICMJE) member journals have required that clinical trials be registered in publicly available trials registers before they are considered for publication.

Objectives:

The research explores whether it is adequate, when searching to inform systematic reviews, to search for relevant clinical trials using only public trials registers and to identify the optimal search approaches in trials registers.

Methods:

A search was conducted in ClinicalTrials.gov and the International Clinical Trials Registry Platform (ICTRP) for research studies that had been included in eight systematic reviews. Four search approaches (highly sensitive, sensitive, precise, and highly precise) were performed using the basic and advanced interfaces in both resources.

Results:

On average, 84% of studies were not listed in either resource. The largest number of included studies was retrieved in ClinicalTrials.gov and ICTRP when a sensitive search approach was used in the basic interface. The use of the advanced interface maintained or improved sensitivity in 16 of 19 strategies for Clinicaltrials.gov and 8 of 18 for ICTRP. No single search approach was sensitive enough to identify all studies included in the 6 reviews.

Conclusions:

Trials registers cannot yet be relied upon as the sole means to locate trials for systematic reviews. Trials registers lag behind the major bibliographic databases in terms of their search interfaces.

Implications:

For systematic reviews, trials registers and major bibliographic databases should be searched. Trials registers should be searched using sensitive approaches, and both the registers consulted in this study should be searched.Clinical trials registers such as ClinicalTrials.gov and portals to trials registers such as the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) are increasingly used to identify ongoing or completed clinical trials. These resources offer important information on the methods and progress of trials likely to be of interest to a range of users, including researchers, clinicians, and patients. The extent to which these resources can be relied upon as a sole source of trials for inclusion in systematic reviews, including Cochrane systematic reviews (CSRs), is the subject of the research study reported here. This study also investigates the most efficient ways that librarians, information professionals, and other searchers can search these resources. Search efficiency was investigated by evaluating the overlap and unique yield of searches in the two resources and by testing four search approaches. The tested search approaches ranged from the very precise (single specific condition search term combined with a single specific intervention search term) to the very sensitive (at least two interventions terms).  相似文献
