Abstract

A “look-up line” (LUL) has been proposed for ice hockey, which is an orange 1?m (40′) warning line (WL) painted on the ice at the base of the boards. The LUL purports to provide an early warning to players to keep their head up prior to and as they are being checked. We determined if players looked up more on a rink with the LUL compared to a traditional Control rink. Elite offensive (O) and defensive (D) players competed 1 vs. 1, while wearing an eye tracker that recorded their quiet eye (QE) and fixation and tracking (F-T) and an electrogoniometer that measured head angle. External cameras recorded skate duration during four skate phases: P1 preparation, P2 decision-making, P3 cut to boards, P4 contact. The QE was the final fixation prior to contact between O and D as they skated towards and across the WL during P3 and P4. Skate phase durations (%) did not differ by rink or rink by position. More QE and F-T occurred on the WL on the LUL rink than on the Control. The expected increase in head angle on the LUL rink did not occur during P3 or P4. Post-hoc results also showed O and D skated further from the boards on the LUL rink, suggesting the players preferred to control the puck on white ice, rather than the orange colour of the LUL rink. More research is needed to determine if these results apply to the competitive setting.  相似文献   

Achievement goals, competition appraisals, and the psychological and emotional welfare of sport participants     

Adie JW  Duda JL  Ntoumanis N 《运动与训练心理学杂志》2008,30(3):302-322

Grounded in the 2x2 achievement goal framework (Elliot & McGregor, 2001), a model was tested examining the hypothesized relationships between approach and avoidance (mastery and performance) goals, challenge and threat appraisals of sport competition, and positive and negative indices of well-being (i.e., self-esteem, positive, and negative affect). A further aim was to determine the degree to which the cognitive appraisals mediated the relationship between the four achievement goals and the indicators of athletes' welfare. Finally, measurement and structural invariance was tested with respect to gender in the hypothesized model. An alternative model was also estimated specifying self-esteem as an antecedent of the four goals and cognitive appraisals. Four hundred and twenty-four team sport participants (Mage=24.25) responded to a multisection questionnaire. Structural equation modeling analyses provided support for the hypothesized model only. Challenge and threat appraisals partially mediated the relationships observed between mastery-based goals and the well-being indicators. Lastly, the hypothesized model was found to be invariant across gender.  相似文献

Subsidizing unmediated document delivery: Current models and a case study     

Minna Sellers  Joan Beam   《The Journal of Academic Librarianship》1995,21(6)

New models for document delivery in libraries are emerging as technology enables end-user ordering through electronic interfaces. Recently Colorado State University (CSUL) tested the viability of providing subsidized unmediated document delivery to the entire university community using UnCover2. The project was analyzed and users were surveyed to evaluate the performance of the service.  相似文献

The third shadow and hybrid genres: horror,humor, gender,and race in Alien Resurrection     

Caroline Joan S. Picart 《传播与批判/文化研究》2013,10(4):335-354

Alien Resurrection (1997) heightens the movements across dark humor and horror, and enables more pronounced and complex conjunctions across the three types of shadows put forward by Rushing/Frentz and Picart, particularly in the case of the monstrous female characters like Ripley and Call. These characters bisociate the realms of first shadow (female bodies), second shadow (products of technology), and third shadow (fearsome female freedom fighters). Nevertheless, both live—a rarity among Frankensteinian cinemyths. Alien Resurrection enables us to glimpse, through a glass darkly, other ways in which the gendered and raced complexities of the Frankenstein cinematic myth may be traced.  相似文献   

'It was Better than Sitting in a Group and Talking'. An Evaluation of a Film-Making Project with Young People in Trouble or 'At Risk' in School     

Gillean McCluskey  Researcher    Gwynedd Lloyd  Head of Educational Studies    Joan Stead  Senior Research Fellow 《Pastoral Care in Education》2004,22(4):34-39

This paper will explore some issues raised by an evaluation of a Scottish video making project which works with young people in trouble or 'at risk' in school. In the paper we reflect on the problems of evaluating work with troubled and troublesome pupils and on the difficulties of both collecting and presenting appropriate evidence. It offers a contribution to continuing debates over educational exclusion and inclusion and to the research literature on strategies for supporting young people in school. The paper also raises key questions about the planning and evaluating of support services for young people by schools.  相似文献
