Key points

  • It is more important to a funder to know that the research advances knowledge and has an impact on the field than that it is published in a prestigious journal (or not).
  • Improving journal quality assurance is more important than improving the business model.
  • Focusing on open access misses the point that journals need to improve their quality standards.

The aim of the present study was to assess the effects of motivating and oudeterous (neither motivating nor demotivating) synchronous music on 400-m sprint performance while controlling for the potential confound of pre-performance mood. A panel of volunteer Caucasian males (n = 20; mean age = 20.5 years, s = 1.2) rated the motivational qualities of 32 musical selections using the Brunel Music Rating Inventory-2. An experimental group of volunteer Caucasian males (n = 36; mean age = 20.4 years, s = 1.4) completed three 400-m time trials under conditions of motivational music, oudeterous music, and a no-music control. Pre-performance mood was assessed using the Brunel University Mood Scale (BRUMS). A series of repeated-measures analyses of variance with Bonferroni adjustment revealed no differences in the BRUMS subscales. A repeated-measures analysis of variance on the 400-m times showed a significant effect (F1.24, 42.19 = 10.54, P < 0.001, eta 2 = 0.24) and follow-up pair wise comparisons revealed differences between the synchronous music conditions and the control condition. This finding supported the first research hypothesis, that synchronous music would result in better performance than a no-music control, but not the second hypothesis, that performance in the motivational synchronous music condition would be better than that in the oudeterous condition. It appears that synchronous music can be applied to anaerobic endurance performance among non-elite sports persons with a considerable positive effect.  相似文献

The United Kingdom's Department for Education has recently changed the nature of the AS‐level examinations normally taken by students aspiring to enter higher education degree courses one year into their post‐compulsory education. In the face of protests from universities and other institutions that this would both harm students’ progression towards the A‐level qualifications, on which entry to English universities is normally based, and make it difficult for universities determining which of their applicants were best placed to benefit from their degree courses, the Department conducted research which it claimed showed that degree outcome could be predicted as well from the results of GCSE examinations taken one year before AS‐levels as from AS‐levels themselves. This paper critiques those analyses and their conclusions showing, through a re‐analysis and extended interpretation of the Department's data, that AS‐levels provide a more reliable predictor of degree performance in 2011 than GCSEs and that many students who performed better at AS‐level than at GCSE gained a place, and performed well, at a university with high entrance standards.  相似文献

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

ABSTRACT

Summarizing my prior work, the only book length treatment of the “acting White” phenomenon (Buck, 2010), I argue that while desegregation was both a moral necessity and a social good, the manner in which desegregation was implemented by White authorities led indirectly to today’s achievement gaps. In the course of desegregation previously all-African-American schools were closed, with their faculty and administrators typically demoted or terminated, and their students sent to previously all-White schools, where they were not always welcomed. This massive social change established scholarly achievement as part of a White identity, not a Black identity. Unfortunately, this diagnoses may not lend itself to easy solutions.  相似文献

The implementation of peer marking within an existing tutorial system is examined. Peer marks were found to be in close agreement with the tutor's, lending credibility to the approach. The benefits of peer marking were discussed with the students, including their possible improvement in examination technique. This teaching approach has the added advantage in that the tutor can more easily act as a facilitator (rather than as an assessor) in the tutorial sessions. At the end of the year an evaluation of peer marking was carried out

Results from a questionnaire showed that five relative advantages of peer marking had been achieved. Further, the students believed that their work had been marked fairly, and that peer marks should count towards their end‐of‐year marks. Peer marking was found tobe most successful, fully complementing a tutorial system of teaching.  相似文献
