The influence of organizational social responsibility on involvement behavior in community sport membership associations

Membership‐based associations are critical to their local communities and the overall social impact of the nonprofit sector. This study examines how organizational social responsibility within nonprofit membership associations influences positive member involvement behaviors, including volunteering, speaking positively about the club, and member loyalty. Self‐administered online questionnaires were completed by 735 members within seven grassroots membership associations in Ontario, Canada offering community‐based sport programs. Results show that members are somewhat aware of and felt positively about their organization's socially responsible efforts. Awareness of these efforts had a positive direct effect on the involvement behaviors of members, including intention to stay involved with their club and speaking positively about their club to others (i.e., word of mouth). Members' level of social consciousness was found to have a positive direct effect on word of mouth. Furthermore, members' positive evaluation of sport clubs' socially responsible initiatives was found to partially mediate the positive relationship between social consciousness and involvement behavior, as well as partially mediate the positive relationship between awareness of those efforts and involvement behavior. Results of this research provide grassroots membership associations with an in‐depth understanding of how their organization's efforts toward social responsibility influence member perceptions and behaviors, which may help them focus their efforts and more effectively manage their social change agenda moving forward.     

网球专项大学生膳食营养调查与分析

通过对湛江师院网球专项学生的膳食营养调查,了解网球专项学生膳食营养状况及其存在的问题,为其合理膳食结构提供科学的指导依据.采用膳食调查记录法,对100名网球专项学生每天膳食摄入量进行记录,然后从食物结构、三大产能营养素的食物来源、营养素摄入状况进行分析.网球专项男、女生食物结构不合理,畜禽肉类、豆类、蛋类、鱼虾类普遍摄入不足.三大产能营养素的食物来源以植物性食物为主,肉食性食物和豆类摄入量较少.男、女生总能量均摄入不足,仅为RNIs标准的87.1%.维生素B1、B2、C均达到RNIs标准供给量,但维生素A摄入严重不足,仅为RNIs标准的47.1%.铁、锌、硒、钙等4种无机盐都低于RNIs推荐供给量,尤其钙为摄入严重不足.湛江师院网球专项学生与他们所从事的运动所需的营养标准有着一定差距,为保证网球队员的运动能力及提高运动成绩,建议开设营养知识讲座及为运动员开设专门的营养配餐.     

体育运动对人体心理健康的影响

随着社会的进步、科技的发展,人们对身心健康需求显得越来越强烈.然而,现代高科技,一方面给人的身心健康提供了良好的医疗保障设施,另一方面它也给人的身心健康产生一些负性的影响,如运动不足症、亚健康、现代"文明病"等.大量研究结果表明身体锻炼是保持和增进心理健康、消除心理疾病的一个重要方法.探讨身体锻炼与心理健康的关系成了近年来国内外运动心理学界的关注焦点.因此,本文在综合国内外最新研究成果的基础上,就这一问题进行了探讨.     

Multiresolution analysis of linearly oriented spatial point patterns

The assumption of direction invariance, i.e. isotropy, is often made in the practical analysis of spatial point patterns due to simpler interpretation and ease of analysis. However, this assumption is many times hard to find in real applications. We propose a wavelet-based approach to test for isotropy in spatial patterns based on the logarithm of the directional scalogram. Under the null hypothesis of isotropy, a random isotropic point pattern should be expected to have the same value of the directional scalogram for any possible direction. Monte Carlo simulations of the logarithm of the directional scalogram over all directions are used to approximate the test distribution and the critical values. We demonstrate the efficacy of the approach through simulation studies and an application to a desert plant data set, where our approach confirms suspected directional effects in the spatial distribution of the desert plant species.

Percentage points for directional anderson-darling goodness-of-fit tests

This paper discusses the problem of assessing the asymptotic distribution when parameters of the hypothesized distribution are estimated from a sample, pointing out a common mistake included in the paper by Sinclair, Spurr, and Ahmad (1990) which introduced two modifications of the Anderson-Darling goodness-of-fit test statistic. Their two test statistics modify the popular Anderson-Darling test statistic to be sensitive to departures of the fitted distribution from the true distribution in one or the other of the tails. This paper uses these new test statistics to develop tests of fit for the normal and exponential distributions. Easy to use formulas are given so the reader can perform these tests at any sample size without consulting exhaustive tables of percentage points. Finally a power study is given to demonstrate the test statistics’ viability against a broad range of alternatives.     

体育交流在国际关系和谐发展中的促进作用——中国体育体制与政策的路径选择

体育与国际政治相互作用,相互影响。当代国际政治呈现出五个主要特点,这些特点既对我国体育产生了深刻影响,也对我国体育体制与政策提出了一系列要求。为此,我国应以提升国家软实力作为体育交流的落脚点,更加重视体育领域的国家软实力建设,创新发展,加快体育体制尤其是竞技体育体制的改革步伐,加强对外体育交流和参与国际体育组织的力度。     

图书馆在科研工作中的功能定位

随着信息化、数字化时代的到来,图书馆的实体服务有被冷落的倾向。新时期图书馆既要立足于自身优势,做好主业,还应做好在科研工作中的功能定位,针对不同的研究方向推出特色服务,开创图书馆事业的新局面。     

Transnational Mobilties in Snowboarding Culture: Travel,Tourism and Lifestyle Migration

Abstract

Drawing upon global ethnographic methods conducted in six countries over seven years, this paper offers the first in-depth examination of the transnational flows and corporeal mobilities in the contemporary physical culture of snowboarding. Focusing on the travel and migration experiences of various groups of snowboarders (that is, tourists, professional athletes and lifestyle sport migrants), and engaging recent work by human geographers, as well as Pierre Bourdieu’s key concepts of field, capital and habitus, this paper reveals fresh insights into the lived transnationalism and global migration of contemporary youth facilitated by the ‘action’, ‘alternative’ or ‘extreme’ sports economy.
