武术套路训练中运动员自我效能感的形成及培养途径

自我效能感是心理学和社会学的重要概念,在竞技武术套路中,运动员的自我效能感对运动员的训练、比赛有着很重要的作用。文章运用文献资料法和逻辑分析的研究方法,以自我效能感创始人班杜拉的自我效能理论为依据,探讨了影响竞技武术套路运动员自我效能感形成的因素及如何培养和提高竞技武术套路运动员的自我效能感,找出在竞技武术套路训练中可以遵循和有效的培养途径,对提高竞技武术套路运动员的训练质量和对未来比赛充满信心有一定的作用。     

Perceived Social Support and Mental Health: Cultural Orientations as Moderators

This study investigated unique and shared effects of social support and cultural orientation on mental health indicators (depressive and anxiety symptoms, stress, and life satisfaction) of 896 college students. Results indicated that perceived social support predicted mental health variables and that cultural orientation variables (independent and interdependent self‐construal) moderated this association. Conclusions and counseling implications for university counselors are discussed on the basis of cultural orientation theory.     

基于信息风险感知的社交网络舆情传播模型研究

结合实际的社交网络使用行为,在分析社交网络舆情传播模式的基础上,构建了社交网络舆情传播模型。详细分析了影响传播概率的主要因素,建立了以信息风险感知为主的传播概率的数学模型。仿真结果表明：获知概率的大小对舆情传播规模、弛豫时间均有影响;而信息风险感知的大小对舆情传播规模的影响不大,对弛豫时间的影响较大,究其根源在于信息风险感知直接决定了传播概率的取值,而传播概率直接决定了网络中传播者的数量。     

互联网金融理财产品使用影响因素研究

依据TAM和TPB模型,按照金融的流动性、收益性和安全性三原则,验证用户使用互联网金融理财产品的关键影响因素。以余额宝为例,收集224个量表作为样本,使用PLS方法,验证互联网金融理财产品结构化方程模型。研究发现,自我效能、感知易用、感知有用在用户使用互联网金融理财产品的影响因素中起着关键作用。自我效能对感知易用、感知有用和使用行为的影响显著。社会影响对用户感知风险和行为意向影响显著,但是影响低于自我效能。     

Beyond the Classroom: Fostering Soft Skills in Pre-Professional LIS Organizations

Are LIS graduates being adequately prepared to work in the information workplace? While students are absorbing valuable knowledge, library school curricula do not foster the essential soft skills students need to thrive in their post-graduate careers. However by being an active member of a graduate student organization, future LIS professionals can gain and hone effective soft skills, such as communication, initiative, curiosity, understanding, and the means to deal with mistakes, while adopting responsibilities that will all ultimately translate to success in the professional workplace, particularly in their first positions following graduation.     

Perceived severity of school bullying in elementary schools based on participants’ roles

The purpose of this study was to examine the perceived severity of school bullying among participants with different roles (victims, bullies, bullies/victims and non-involved individuals) and to determine whether interactions between type of bullying and participant roles exist. Two Olweus-like global items and a revised School Bullying Severity Scale for elementary students were used in this study. A total of 1816 valid surveys completed by students in grades 5 and 6 (mean age = 11.5, SD = .84) were collected. Data were analysed using a mixed-model two-way ANOVA. The results revealed a significant main effect of type of bullying. Physical and verbal bullying were perceived as more severe than relational and cyberbullying. A significant two-way interaction between bullying category and participant role was also identified. Bullies did not perceive the four types of victimisation behaviours differently, whereas victims and bullies/victims both rated physical victimisation as most severe and cyber-victimisation as least severe. However, effect sizes were small. Implications for bullying prevention and intervention are discussed.     

有氧运动强度监测指标特征分析与研究

研究了运动指标中的心率、代谢当量、主观感觉程度与运动能量消耗等指标特征,首先,从心率对运动负荷的基本应答特征、运用目标心率安排锻炼负荷强度、心率测量的特征、心率的运动强度监测等方面分析了心率指标特征;其次,阐述了代谢当量指标与主观感觉程度特征及其分级指标;再次,从气体代谢分析仪与心率测试法等方面分析了运动能量消耗测定方法;最后进行了总结与建议。     

网络动态干扰监控的信任感知推荐算法设计

网络用户信任感知推荐的准确性设计是提高用户间的社交网络辅助信息信任度的重要依据。传统的网络用户信任感知推荐算法采用的是基于社交网络服务和用户评分的推荐系统,主观性较大,协同过滤效果不好。提出一种基于网络动态干扰监控的信任感知推荐算法设计新方法,设计自适应神经模糊系统网络动态干扰监测算法,构建基于向量空间模型的信任度评价指标体系结构,通过调整网络拓扑权重向量设置信任度周期响应加权变量自适应函数,有效降低迭代算法的运算成本,避免了自适应神经模糊系统网络动态干扰监测加权权重成固化状态,提高抗干扰性能。实验结果表明,算法能使社交网络感知推荐模型的预测误差减少,推荐可靠性优于传统方法。     

乐观与离职倾向关系的实证研究——领导成员关系和组织支持感的调节作用检验

对广东省内300家企业进行了大规模的问卷调查,最终获得了1533个有效员工样本,实证研究发现:乐观对于员工离职倾向具有显著的负向影响,并且在高水平的领导成员关系和组织支持感的工作环境下,这一负向关系会加强;反之,低水平的领导成员关系和组织支持感情况下则不会影响这一负向关系。     

数字鸿沟视角下社会图书馆系统用户感知差异性实证研究

百度产品如百度知道、百度百科、百度文库等是基于Web2.0应用的知识共享平台,用户不仅可以搜寻知识,而且可以贡献知识,被认为是重要的社会图书馆系统。本文结合数字鸿沟,探讨用户对百度产品易用性（能力鸿沟）和有用性（产出鸿沟）的感知差异,旨在推动社会图书馆系统的健康发展。首先进行量表设计;然后基于量表搜集数据;再针对数据进行分析,包括测量模型有效性检验、易用性和有用性的频数统计及相关分析;结合数据分析,用图的方式展现了用户在感知差异性上的分布状态,发现能力鸿沟和产出鸿沟之间存在高度相关性。
