The year 2012 provided an opportunity to celebrate sporting history during the year when London staged that most historical of international sporting events, the Olympic Games. However, the Department for Culture, Media, and Sport, and the London Organising Committee of the Olympic Games (LOCOG) made no reference to sporting history within official documentation, and there was no mention of sport in the Cultural Olympiad programme. This paper aims to understand the role of the Sports Heritage Network in exploring England's sporting heritage, despite being excluded from the official planning of the London 2012 Olympic Games. This affiliation of museums and archives with an interest in England's sporting past recognised the potential of the 2012 Olympic Games and established a community exhibition programme, Our Sporting Life, which aligned with LOCOG's aims and objectives. This paper evaluates the outputs and outcomes of Our Sporting Life and aims to understand why it was not supported financially or integrated into the official Cultural Olympiad programme. The data collection for Our Sporting Life is analysed and critiqued, and the impact of the programme is considered using the Generic Learning Outcomes and the Generic Social Outcomes frameworks. Our Sporting Life delivered over a hundred exhibitions and reached over one million people, with outcomes that included increasing knowledge and understanding, and strengthening public life. It provides an off-the-shelf methodology for future major sporting events and, as such, its omission from the London 2012 Cultural Olympiad can be regarded a lost opportunity.  相似文献

ABSTRACT

There is little empirical research related to the readiness and capacity of academics for team-based collaboration. This case study used the existing literature about collaboration as a term of reference to examine the perceptions of a group of academics engaged in course design and how prepared they were individually and as teams for collaboration. The study found that participants recognised and understood the key elements that distinguish collaboration from other forms of interaction. However, they did not express a depth of understanding about the cognitive and social capacities required for collaboration and the skills, structures and processes necessary to enable team-based collaborative practice. While the participants felt they were willing and largely prepared as individuals for collaboration, closer scrutiny indicated substantial variation in their reports about the willingness, knowledge and skills of the teams on which they served. In addition, participants reported that current conditions at the institutional level serve as inhibitors to collaboration in course design. This included the absence of committed leadership and organisational supports for collaboration. Participants described the dominant culture as more supportive of individualised, competitive and hierarchical work practices. Under these work conditions, participants noted a reliance on individuals’ goodwill to collaborate in the absence of broader organisational structures and support.  相似文献

Faculty retention is of increasing importance in the current economic climate. We examined the role of an institution’s environmental conditions (e.g., climate, collegiality, and administration) in faculty well-being (i.e., job satisfaction, intent to leave, emotional and physical health). Women reported significantly lower well-being and a more negative perception of all environmental conditions than men. Intriguingly, for both men and women, the more institutional support perceived by faculty members for work-life integration, the more positive their well-being. Policies that support work-life integration, often viewed as merely a “women’s issue,” may encourage the retention of both men and women faculty members.  相似文献

Children's understandings of the shape and relative sizes of the Earth, Sun and Moon have been extensively researched and in a variety of ways. Much is known about the confusions which arise as young people try to grasp ideas about the world and our neighbouring celestial bodies. Despite this, there remain uncertainties about the conceptual models which young people use and how they theorise in the process of acquiring more scientific conceptions. In this article, the relevant published research is reviewed critically and in-depth in order to frame a series of investigations using semi-structured interviews carried out with 248 participants aged 3–18 years from China and New Zealand. Analysis of qualitative and quantitative data concerning the reasoning of these subjects (involving cognitive categorisations and their rank ordering) confirmed that (a) concepts of Earth shape and size are embedded in a ‘super-concept’ or ‘Earth notion’ embracing ideas of physical shape, ‘ground’ and ‘sky’, habitation of and identity with Earth; (b) conceptual development is similar in cultures where teachers hold a scientific world view and (c) children's concepts of shape and size of the Earth, Sun and Moon can be usefully explored within an ethnological approach using multi-media interviews combined with observational astronomy. For these young people, concepts of the shape and size of the Moon and Sun were closely correlated with their Earth notion concepts and there were few differences between the cultures despite their contrasts. Analysis of the statistical data used Kolmogorov–Smirnov Two-Sample Tests with hypotheses confirmed at K–S alpha level 0.05; rs : p?<?0.01.  相似文献

The purpose of this study is to provide evidence of technique changes during learning a sports-specific skill, the looped bar longswing (LLS). Thirteen male participants with no previous high bar experience took part in a training study. Kinematic data were collected using a CODA motion analysis system (200 Hz) during eight weekly testing sessions. Analyses focused on the amplitude of swing and the functional phase (FP) actions, defined by the rapid flexion to extension of the shoulders and extension to flexion of the hips as the performer passed through the lower vertical. Three groups were identified based on the number of sessions it took each participant to perform the LLS (G1: most successful, G2: intermediate, and G3: least successful). All participants were able to significantly increase swing amplitude over the training period (p < 0.05). For each participant the hip FP started significantly: later for G1, earlier for G2, and did not change for G3. Extension actions at the shoulders were dissimilar to those reported for elite gymnasts performing the longswing. The FP of the hips provides a mechanism to distinguish between the learners of different skill levels. The study has provided support for a single-subject design when investigating technique changes during learning.  相似文献

Abstract

In recent years, a method of plyometrics (exercises that cause a rapid lengthening of a muscle prior to contraction) called depth jumping has become a part of the training routine of many athletes. Two experiments are described in which the effectiveness of the exercises is examined. In Experiment 1, undergraduate students in beginning weight training classes trained with three different jumping programs: (1) maximum vertical jumps, (2) 0.3 m depth jumps, and (3) 0.75 m and 1.10 m depth jumps. In addition, all groups also lifted weights. In Experiment 2, a weight training class and the volleyball team at Brigham Young University-Hawaii were divided into two groups. One group lifted weights and performed 0.75 and 1.10 m depth jumps. The other group only lifted weights. In Experiment 1, the three training programs resulted in increases in one repetition maximum (1 RM) squat strength, isometric knee extension strength, and in vertical jump; however, there were no significant differences between treatments. In Experiment 2, all groups made significant increases in vertical jump, except the group of weight lifters, who did no jumping. It was concluded that depth jumps are effective but not more effective than a regular jumping routine.  相似文献

Abstract

Because of increasing numbers of serious sports-related injuries at all levels of participation, the National Operating Committee on Standards for Athletic Equipment (NOCSAE) was formed. Among their activities aimed at improving the safety of sports participation was the development of standards for impact resistance in both new and refinished football helmets. These standards include not only recommendations as to safe levels of resistance to impact but recommendations as to the number of helmets to be tested from each group of helmets undergoing a refinishing process.

In this study the various sources of variability in the testing procedure are examined. These sources include helmet-to-helmet variability, testing variability, and basic measurement error. A careful examination of this variability in the context of the NOCSAE-recommended testing procedures for recertifying helmets reveals an inadequacy in the NOCSAE standard, in that the probability of returning unsafe helmets to the playing field is unacceptably high.  相似文献

Purpose: This study investigated perception and action coupling as reflected in a mapping between time-to-contact (TTC) and time-to-peak-velocity (TPV) for children and youths aged 7 to 8, 11 to 12, and 15 to 16 years old and adults aged 19 to 20 years old performing a task that allowed the participants to self-select the interception position in a baseball-like batting game on a graphics tablet. Method: The moving object to be hit for distance had curvilinear trajectories toward the hitter that were determined by simulated weightings of gravity and velocity. Results: Successful interceptions in all age groups were characterized by a mapping of mean TTC and TPV and a higher correlation of these variables with increasing age. The object was hit at approximately 90% TPV so that the implement was still accelerating on contact—an adaptive task feature for a striking distance criterion. Conclusion: The results are consistent with theories of perception–action coupling that are congruent with the ecological and dynamical approaches to action where TTC, a source of environmental information, is mapped relative to TPV, largely independent of the particular kinematic task demands of the approaching object. The organization of the coupling of TTC prior to TPV was evident across all age groups and is evidence for a common strategy for this type of interceptive action. The age-related changes in the strength of the relationship between TTC and TPV are evidence of increased sensitivity to the coupling between TTC and TPV.  相似文献
