存在于变化——从《安乐乡的一日》看华人身份的追寻

作为一群移民,华人既由于时空的疏离而与祖国有着隔膜的尴尬状态,又无法得到移入国——美国的认同,他们应当如何找寻自身的身份就成了一个无法回避的问题。拟将通过对白先勇的小说《安乐乡的一日》中的人物形象分析来探析华人移民在美国这样一个异质的文化环境中如何维系自己的文化身份。     

Why do high jumpers use a curved approach?

Currently, all elite high jumpers use the Fosbury Flop technique with a curved approach. This suggests that the curved approach presents some clear advantage, although there is no general agreement upon the mechanism or the mechanics. This study aimed to determine the characteristics of the approach curve and to investigate how it contributes to the generation of somersault rotation. A simple theoretical model was used to demonstrate that a tightening approach curve would change the inward lean towards the centre of the curve into outwards lean. Three-dimensional video analysis was used to record the performances of two elite male high jumpers in competition. It was found that in each case the radius of the approach curve and the inward lean angle both decreased towards the end of the approach. The amount of outward lean angular velocity generated was shown to be a major proportion of the required somersault angular velocity for a jump. It was concluded that the main advantage of a curved approach was that it resulted in the generation of somersault velocity providing the curve tightened towards the end of the approach.     

Physiological variables and performance markers of serving soldiers from two “elite” units of the British Army

Abstract

The aim of this study was to compare selected physiological variables and performance markers of soldiers from two “elite” units of the British Army. Ten soldiers from each of the two units were recruited for this study (n = 20). All participants completed three tests while carrying a 20 kg backpack load: (1) a maximal treadmill test using the Bruce protocol; (2) a 2 mile backpack run test specific to Unit A on a consistently flat tarmac road; and (3) a 29 km time-trial over hilly terrain typical of a mountainous area used by Unit B for performance assessment. Heart rate, maximal blood lactate concentration and performance (run time) were assessed during all three tests, with peak oxygen uptake also being measured during the maximal treadmill test. Measurements of anthropometry, isokinetic strength and mental toughness (MT48) were also recorded. There were no significant differences in terms of performance markers between the units (P > 0.05). Performance on the maximal treadmill test correlated with performance on the 2 mile backpack run test (r = ?0.57) and 29 km time-trial (r = ?0.66). Performance on the 2 mile backpack run test in turn correlated with 29 km time-trial performance (r = ?0.77), accounting for 59% of the variance. In conclusion, the maximal treadmill test and the 2 mile backpack run test are useful indicators of performance on the arduous hill march and could be employed in the screening and selection of potential recruits.

Value-based argumentation for designing and auditing security measures

Designing security measures often involves trade-offs between various types of objectives. Multiple stakeholders may have conflicting demands and may have different ideas on how to resolve the resulting design conflicts. This paper reports on an application of value-sensitive design. Based on argumentation theory and social values, the paper develops a structured approach for discussing design conflicts, called value-based argumentation. The application domain examined in the paper is concerned with physical safety and security issues that arise in cross-border shipments. We first identify the kinds of dialogues that take place in this domain, in particular, audit dialogues to determine whether security measures comply with regulations. Based on argumentation theory we develop a formal language and a diagramming approach intended to facilitate parties in identifying, discussing and reaching agreement about security risks and corresponding mitigation measures. Trade-offs can be dealt with by making underlying values explicit. Using a stylized example, the approach was successfully taught to practitioners working with EU customs regulations. Practitioners generally found the approach helpful, in particular to bring out implicit underlying motivations. We conclude by discussing how our approach can be generalized to other kinds of dialogues involving design conflicts.

Sex Bias and the Validity of Believed Differences between Male and Female Interscholastic Athletic Coaches

Abstract

Previous research indicates that young athletes as well as athletic administrators hold gender-role stereotypical beliefs about coaches that disfavor females. The validity of two such beliefs (lack of qualified female coaches and time constraints due to family responsibilities) was examined in a statewide survey of 256 female and 296 male interscholastic coaches and a nationwide survey of 2,719 male and 1,449 female interscholastic coaches. Statistical analyses (p < .001) indicated that female coaches were (a) more qualified than their male counterparts with respect to coaching experience with female teams, professional training, and professional experience; (b) as qualified as male coaches with regard to intercollegiate playing experience; and (c) less qualified than male coaches with respect to high school playing experience and coaching experience with male teams. Findings also indicated that male rather than female coaches more often experienced time constraints due to family responsibilities.
