中学生的人格五因素、感知的社会支持与自尊的关系

以北京和西安1432名初一、初二、高一、高二的中学生为对象,采用小五人格学生问卷、社会关系网络问卷、Rosenberg整体自尊量表,综合探讨中学生的人格五因素、感知的社会支持与自尊的关系。结果发现:(1)人格五因素中的情绪性、开放性,感知的社会支持中的社会性支持、冲突惩罚、满意度对中学生的自尊具有显著预测作用;(2)在人格与社会支持对中学生自尊的联合作用中,人格的作用更为显著,因而是主要的;(3)中学生的人格特征会直接影响自尊,也会影响感知的社会支持,从而间接影响自尊;(4)对男生和女生的自尊产生影响的人格特点和感知的社会支持特点不同。本研究对于促进中学生自尊和心理健康水平的教育实践具有理论指导意义。     

Improving sexual health for young people: making sexuality education a priority

How well do young people understand their developing sexuality and what this means? This paper reports on findings from the Our Lives: Culture, Context and Risk project, which investigated sexual behaviour and decision-making in the context of the everyday life experience and aspirations of Indigenous and non-Indigenous young people (16–25 years) in the Northern Territory, Western Australia and in South Australia. Using qualitative data, this paper focuses on what participating young people thought was necessary to improve the quality of sexuality education. Participants suggest that current forms of sexuality education are too clinical, didactic and unengaging, and are missing in relevant content. Young people requested more information on relationships, first sexual experiences and negotiating condom use. These requests indicate that young people realise that they need more knowledge in order to have healthy relationships, which conflicts with the popular belief that providing young people with open, honest information around sex will encourage them to have sex or increase sexual risk taking. Making sexuality education more of a priority and listening to the needs of young people could be a positive step towards improving sexual health and well-being.     

知觉价值、社会影响、自我认同与进口名牌包购买行为之研究

在文化、创意、美学意识盛行的现代社会,对年轻的消费族群而言,注重的不仅仅是产品的实用面及基本需求,"个人品味"也是重要的要求,产品的外型、美观、品牌、包装、设计感都列入购买考虑。国际精品名牌包的消费则是现代年轻人展现自我品味的表现。但青少年阶段在群体意识上表现又特别的强烈,故在精品购买决策上又会受到社会性的影响。年轻人对于进口名牌包的消费与影响其消费的因素相当复杂,值得深入的探讨。通过探讨知觉价值、社会影响、自我认同等因素对青少年购买进口名牌包之影响,发现青少年的精品消费有很强的社会性影响,不论是规范性或信息性。但青少年也不会一味地追求炫耀或展现财富而去采购高知名度的名牌包。     

Prospective teachers’ perceptions of instrumentality,boredom coping strategies,and four aspects of engagement

This study examined the mediating roles of prospective teachers’ boredom coping strategies (i.e. cognitive-approach, behavioral-approach, cognitive-avoidance, and behavioral-avoidance strategies) in the relationships between their perceptions of instrumentality and four aspects of engagement (i.e. agentic engagement, behavioral, engagement, emotional engagement, and cognitive engagement). A total of 521 prospective teachers participated voluntarily in the study. In addition to the latent factor and observed factor correlation analyses, a series of structural equation modeling analyses were conducted in order to examine the mediating roles of boredom coping strategies. The results demonstrated that perceived instrumentality, boredom coping strategies with the exception of cognitive-avoidance orientation, and four aspects of engagement were significantly related to each other. The results also showed that the relationships between perceived instrumentality and agentic engagement, behavioral engagement, emotional engagement, and cognitive engagement were slightly, but significantly mediated by cognitive-approach orientation. Implications for teacher education and directions for future studies were also discussed in the present study.     

Application of velocity loss thresholds during free-weight resistance training: Responses and reproducibility of perceptual,metabolic, and neuromuscular outcomes

ABSTRACT

The aim of this study was to investigate the differences and long-term reliability in perceptual, metabolic, and neuromuscular responses to velocity loss resistance training protocols. Using a repeated, counterbalanced, crossover design, twelve team-sport athletes completed 5-sets of barbell back-squats at a load corresponding to a mean concentric velocity of ~0.70 m·s^?1. On different days, repetitions were performed until a 10%, 20% or 30% velocity loss was attained, with outcome measures collected after each set. Sessions were repeated after four-weeks. There were substantial between-protocol differences in post-set differential ratings of perceived exertion (dRPE, i.e., breathlessness and leg muscles, AU) and blood lactate concentration (B[La], mmol·L^?1), such that 30%>20%>10% by small to large magnitudes. Differences in post-set countermovement jump (CMJ) variables were small for most variables, such that 30%<20%<10%. Standard deviations representing four-week variability of post-set responses to each protocol were: dRPE, 8–11; B[La], 0.8–1.0; CMJ height, 1.6–2.0; CMJ PPO, 1.0–1.8; CMJ PCV, 0.04–0.06; CMJ 100ms-Impulse, 5.7–11.9. Velocity loss thresholds control the magnitude of perceptual, metabolic, and neuromuscular responses to resistance training. For practitioners wanting to reliably prescribe training that can induce a given perceptual, metabolic, or neuromuscular response, it is strongly advised that velocity-based thresholds are implemented.

Attention‐Deficit/Hyperactivity Disorder Symptoms,Perceived Stress,and Resilience in College Students

This research investigated the relationships among symptoms associated with attention‐deficit/hyperactivity disorder (ADHD), perceived stress, and resilience in college students. In our study of 558 college students (175 men, 383 women), we confirmed the hypothesis that the relationship between ADHD symptoms and perceived stress is mediated by protective factors associated with resilience. The relationships were not significantly moderated by sex. Implications for increasing resilience in college students and lowering perceived stress for college students are discussed.     

公正感研究对公共管理的意义

在介绍和评论组织公正感研究成果的基础上,提出公众的社会公正感是反映社会公正价值体现的一个灵敏指标,在公共管理领域开展社会公正感研究十分必要;认为在决策程序上规范政府行为、保障公民有效参与是提高公共管理水平的关键,加强政府与公众之间的信息交流与互动是提高社会公正感、促进公共管理目标实现的有效途径;指出当前要特别重视因分配结果和社会利益阶层收入差距引发的社会不公正感和不稳定因素,做好监测和预警工作。     

创业失败经历影响新创企业创业导向的实证研究

本文关注创业者的创业失败经历对新创企业创业导向的超前行动性、创新性以及风险承担性3个维度的影响，并探究感知创业环境的调节作用。利用中国跨省份1 133家新创企业的一手调研数据进行实证分析，结果显示：创业失败经历对超前行动性、创新性和风险承担性3个维度具有显著的正向影响，即创业失败经历越多，创业者的超前行动性、创新性和风险承担性越强；感知创业环境作为调节变量，加强了创业失败经历对创新性的正向影响，削弱了创业失败经历对风险承担性的正向影响。
