Effects of psychosocial variables in the similarity and interdependence of physical activity levels among adolescent best friend dyads     

Vítor P. Lopes  Carl Gabbard  Luis P. Rodrigues 《Journal of sports sciences》2016,34(9):821-828

Given that physical activity (PA) tends to decrease with age during adolescence, addressing factors that affect change is important. This study examined the similarity and interdependence of PA as influenced by psychosocial factors among adolescent best friend dyads. A total of 660 adolescents, representing 330 best friend dyads, completed questionnaires with regard to PA, sitting time, perceived exercise benefits and barriers, physical self-perception and social support for PA. Dyads were also identified as reciprocal and non-reciprocal best friends; reciprocal means that both considered each other best friends and non-reciprocal were those in which only one considered the other a best friend. Data were analysed using a hierarchical linear model framework. Results indicated significant similarities between reciprocal best friend dyads for PA and sitting time, and for sitting time in non-reciprocal best friends (P values <.01). Psychosocial variables were associated with PA in reciprocal best friend dyads and with sitting time in reciprocal and non-reciprocal best friend dyads. Best friend gender, regular sports practice of the person, perceived exercise barriers of the best friend and best friend social support were the best predictors for PA.  相似文献   

资源依赖、关系质量对联盟绩效影响的实证研究   总被引：8，自引：1，他引：8  

贾生华  吴波  王承哲 《科学学研究》2007,25(2):334-339

基于文献研究,认为企业间的资源依赖性和关系质量分别影响了联盟的潜在价值和潜在价值的实现程度,进而影响联盟绩效。通过对北京市156家企业的实证研究表明,企业间资源的结构依赖性、信任、承诺和沟通对联盟绩效有显著影响。  相似文献   

集体心理所有权影响创业团队绩效的机制研究   总被引：1，自引：0，他引：1  

梁燕  赵琛徽 《科研管理》2021,42(9):150-156

   “双创”背景下如何提高创业团队绩效与促进创业成功受到社会各界的普遍关注。文章基于群体心理学相关理论观点,运用SPSS21.0及MPLUS7.0对国内173家创业团队的样本数据进行分析,探讨了集体心理所有权与创业团队绩效之间的中介机制与边界条件。研究发现：创业团队中集体心理所有权对团队学习和创业团队绩效均具有正向影响;团队学习在集体心理所有权与创业团队绩效间具有部分中介作用;团队任务相互依赖在两者的中介机制中具有负向调节作用：团队任务相互依赖越高,集体心理所有权对团队学习与创业团队绩效的正向影响越弱,团队学习在集体心理所有权与创业团队绩效之间的中介作用越弱。本研究提供了从集体心理所有权与团队任务设计角度提高创业团队绩效的有效路径。  相似文献   

基于不对称互赖理论下的美台经济关系研究     

舒均治 《怀化学院学报》2014,(4):60-63

美台经济关系显而易见不是纯粹的经济关系,它始终是美台战略、政治关系的一个方面,具有十分复杂的政治、经济意义。美台经济关系是一种不对称相互依赖的经济关系,美台经济关系由冷战时期台湾对美国的单向深度依赖,逐渐减轻为不对称的互赖关系。冷战后,在两岸经贸关系迅猛发展的同时,表面上呈现两岸经贸关系取代美台经济关系的趋势,特别是美台间的双边直接贸易关系也确实较冷战期间减弱,但大陆、美国与台湾经济的三角关系的形成,使得美台经济关系实质上并未受到太深影响,台湾对美国市场仍然深度依赖,只是在形式上与较冷战期间相较而更加迂回曲折。  相似文献

耿紫珍  刘新梅  沈力 《科研管理》2012,33(8):113-119,136

基于激发型信息处理的视角,探讨了合作目标互依性、知识共享和团队反思与科研团队创造力之间的关系,构建了相应的概念模型。运用结构方程模型和225个有效科研团队样本对所提出的假设进行检验。实证研究结果表明,合作目标互依性对科研团队创造力有积极影响;知识共享与团队反思在合作目标互依性与科研团队创造力之间具有完全中介效应,而知识共享对团队反思有正向促进作用。研究结果打开了合作目标影响科研团队创造力的信息处理黑箱,扩展了激发型信息处理视角在团队创造力研究领域中的应用。  相似文献   

Teacher educators’ collaboration in subject departments: collaborative activities and social relations     

Henderijn Heldens  Anouke Bakx  Perry den Brok 《Educational Research and Evaluation》2013,19(7-8):515-536

Teacher educators’ collaboration plays an important role in the improvement of teacher education. Many studies in educational research focus on collaboration from 1 particular perspective. A focus on 2 perspectives, a qualitative (focusing on collaborative activities) as well as a quantitative (focusing on relations) perspective, and relating both perspectives, can add to our knowledge. Data were collected in 3 subject departments of a teacher education institute. Findings indicated that educators’ collaborative networks inside the departments could gain from more coherent and dense relations, and that key players were important to support and sustain collaboration. Both perspectives were mildly related, correlations were found for “degree” and “information” (r = .31, p < .05), “degree” and “joint work” (r = .38, p < .01), and “reciprocity” and “joint work” (r = .33, p < .05), no correlations were found for “degree” or “reciprocity” and “discussing”. At the department level, only mathematics showed significant correlations. Results indicated that, in further research, qualitative aspects as well as quantitative aspects should be included.  相似文献

Connective Leadership in an Interdependent and Diverse World     

Jean Lipman-Blumen 《Roeper Review》2017,39(3):170-173

Expressing strong agreement with Robert Sternberg’s rationale for changing our methods for identifying intelligence, this analysis emphasizes connections with leadership failures. In recognition that a changing world requires connective ethical leadership, it discusses the nine-factor behavioral model portraying achieving styles that can facilitate effective leadership in a changing world. Leaders operating along these lines can identify high-potential initiatives and artfully adjust their behaviors to achieve the best outcomes.  相似文献   

技术创新网络中企业合作动机及合作行为的分析     

李玲 《技术与创新管理》2010,31(4):373-376,391

技术创新网络是由不同合作主体形成的,加入网络的企业具有各自的合作动机,合作动机的差异性直接导致了企业在合作过程中的不同合作行为。在对相关文献梳理的基础上,将网络内企业的合作动机分为效率导向、竞争导向、学习导向与信息导向,并在理论上分析了不同合作动机对合作行为的具体影响。研究对于正确理解技术创新网络中企业的合作行为,制订企业的合作政策具有重要意义。  相似文献
