A season-long team-building intervention: examining the effect of team goal setting on cohesion

The purpose of the current study was to determine whether the implementation of a season-long team-building intervention program using team goal setting increased perceptions of cohesion. The participants were 86 female high school basketball players from 8 teams. The teams were randomly assigned to either an experimental team goal-setting or control condition. Each participant completed the Group Environment Questionnaire (GEQ; Carron, Brawley, & Widmeyer, 2002; Carron, Widmeyer, & Brawley, 1985), which assessed cohesion at both the beginning and end of the season. Overall, the results revealed a significant multivariate effect, Pillai's trace F(12, 438) = 2.68, p = .002. Post hoc analyses showed that at the beginning of the season, athletes from both conditions did not differ in their perceptions of cohesion. However, at the end of the season, athletes in the team goal-setting condition held higher perceptions of cohesion than athletes in the control condition. Overall, the results indicated that team goal setting was an effective team-building tool for influencing cohesiveness in sport teams.     

To preserve or enhance precious memories: a segmented market analysis of the history museum in Singapore

This study examines the value placed on museums by patrons and non-patrons and investigates the factors that affect this valuation with a view to boost visitorship. The total economic value of Singapore’s History Museum is at least US$57 million, and this is high relative to other countries, a fact which can be used to justify increased government funding towards museums as cultural capital. Females and high income people are the target groups for increased visitation, while among the non-patrons, the ethnic majority is another potential clientele. Somewhat surprising is the finding that neither patrons nor non-patrons see the museum as having significant tourist value, and contrary to prospect theory, there is a preference for enhancing the museum’s services over keeping the museum. These findings provide some direction for the management of the museum to improve its visitor appeal.     

Superior short-term learning effect of visual and sensory organisation ability when sensory information is unreliable in adolescent rhythmic gymnasts

Rhythmic gymnasts specialise in dynamic balance under sensory conditions of numerous somatosensory, visual, and vestibular stimulations. This study investigated whether adolescent rhythmic gymnasts are superior to peers in Sensory Organisation test (SOT) performance, which quantifies the ability to maintain standing balance in six sensory conditions, and explored whether they plateaued faster during familiarisation with the SOT. Three and six sessions of SOTs were administered to 15 female rhythmic gymnasts (15.0 ± 1.8 years) and matched peers (15.1 ± 2.1 years), respectively. The gymnasts were superior to their peers in terms of fitness measures, and their performance was better in the SOT equilibrium score when visual information was unreliable. The SOT learning effects were shown in more challenging sensory conditions between Sessions 1 and 2 and were equivalent in both groups; however, over time, the gymnasts gained marginally significant better visual ability and relied less on visual sense when unreliable. In conclusion, adolescent rhythmic gymnasts have generally the same sensory organisation ability and learning rates as their peers. However, when visual information is unreliable, they have superior sensory organisation ability and learn faster to rely less on visual sense.     

协同导向：美国青少年体质健康政策的演进与启示

协同导向是美国青少年体质健康政策的突出特征,主要体现在政策文本协同和政策制订协同两方面.在政策文本协同方面,通过梳理历年来体质测量、体育、教育、校园卫生和营养等方面的政策演进过程,发现其体现出较明显的健康促进导向作用.在政策制订协同方面,除了政府相关部门外,社会组织和社会精英人物也都积极参与政策制订,形成了国家政府部门和各界参与的有机融合.我国青少年体质健康亦面临类似问题,可借鉴美国经验,注重体育与营养政策的协同作用,注重跨界政策制订主体的协同参与,强化学校和社区等场域的协同连接,凸显学生校园营养行为的国家责任.     

基于体育产业需求下我国体育翻译人才分层次培养的综合模式研究

通过辨析“体育外语人才”“体育英语人才”“体育翻译人才”的概念,界定出体育翻译人才的概念.在此基础上借鉴NAETI的等级划分标准,从体育翻译人才能力层次分为三级并提出高级体育翻译人才的培养将为重中之重.通过对“体育+外语”和“外语+体育”在体育翻译人才培养中优劣分析,提出培养应重点放在“外语+体育”方向上或者外语院校与体育院校联合培养上.在此基础上构建了高级体育翻译人才的培养模式.     

高温环境下咖啡因对耐力大学生运动员运动中唾液sIgA、溶菌酶的影响

探讨高温环境下运动中,口服咖啡因对男大学生运动员运动中唾液分泌型免疫球蛋白A（sIgA）和溶菌酶（lysozyme,LZM）的影响。采用实验研究方法,以13名男性耐力性项目大学生运动员为研究对象。每名研究对象在温度为33℃、相对湿度为65%的实验室完成两次实验（咖啡因运动实验和对照运动实验）。每次实验中,采集运动前60 min、运动前即刻、运动20 min、运动结束即刻的唾液样本,测定唾液sIgA、LZM的浓度。实验结果显示,口服咖啡因对高温环境下耐力大学生运动员运动中唾液sIgA无影响,但会降低唾液LZM水平,高温环境、中等强度运动使男耐力大学生运动员唾液sIgA和LZM的水平升高。     

New media environments’ comparative effects upon intercultural sensitivity: A five-dimensional analysis

An experimental 2 (channel) × 2 (gender) × 3 (time) mixed factorial design (N = 159) was applied to test and compare how individual dimensions of intercultural sensitivity might be affected by two channels: a virtual environment (i.e., Second Life^®) versus a Web environment. Using a modified version of Chen and Starosta's Intercultural Sensitivity Scale (ISS), the study sought to identify which of the five ISS dimensions played the most influential role in intercultural sensitivity outcomes: interaction enjoyment, interaction engagement, interaction confidence, interaction attentiveness, or respect for cultural differences. Results showed that one's willingness and effort toward understanding an intercultural interaction – interaction attentiveness – played the greatest and most statistically significant role in intercultural sensitivity outcomes, and that this effect was greatest within the virtual environment channel. Gender effects were also found, in which men experienced greater enjoyment but women expressed more attentiveness.
