儿童网络使用与学业成就：有调节的中介模型

摘 要 为探讨网络使用对学业成就的影响及其作用机制,从自我效能感理论的角度使用问卷对425名小学生进行调查。结果表明：（1）网络使用完全通过学习效能感的中介作用正向预测学业成就;（2）学习效能感中介作用受到开放性的调节,即在开放性高的个体中,学习效能感在网络使用与学业成就之间的中介效应不显著;在开放性低的个体中,学习效能在网络使用与学业成就之间有显著的中介效应。研究结果揭示了网络使用对学业成就的影响与作用机制,对家长、教育工作者根据儿童的个人特质对网络使用进行适度引导有启示意义。     

Self‐efficacy or perceived behavioural control: Which influences consumers' physical activity and healthful eating behaviour maintenance?

This research investigated the role of a commercial program, Michelle Bridges 12 Week Body Transformation (MB12WBT), that uses a variety of tools including social support to influence weight management behaviours such as exercising and eating healthfully. The need for research into weight management remains current given obesity rates have continued to increase in recent decades. Weight management is a complex behaviour that for many consumers involves barriers that influence their commitment to continue exercising and eating healthily. The Theory of Planned Behaviour is frequently used to explain, and to a lesser extent predict, behaviours such as physical activity and healthy eating; however, there is much debate as to whether a perceived behavioural control variable or self‐efficacy is the best predictor of behaviour. Structural equation modelling was used to analyse data from a sample of 724 respondents who answered a baseline and three month follow‐up survey. The analysis revealed self‐efficacy and perceived behavioural control were two distinct constructs. Self‐efficacy was a better predictor of behaviour than perceived behavioural control variables as suggested in the original Theory of Planned Behaviour. Furthermore, self‐efficacy had a significant impact on exercising and eating healthfully behaviour. The findings and implications for both behaviour change theory and practice are discussed.     

数字技术对个体的影响

数字原住民的相关论述为解释数字技术对个体的影响提供了切入点,数字原住民是指在数字化环境中成长的个体,他们在成长过程中与数字技术互动的经历,不仅会使其表现出相应的行为特质,也会对他们的认知和生理结构产生广泛的影响。生态科技亚系统理论和数字原住民假说从宏观和微观的视角为这些论述提供了理论支持,认知心理学和认知神经领域的研究则对其内容进行了实证检验。在相关研究成果的基础上,未来研究需要进一步扩展研究的方向、广度和深度。     

The Relevance of Self‐Evaluations for Students' Career Optimism

This study investigated how people's beliefs regarding their vocational abilities (i.e., career decision self‐efficacy) are associated with their perceived academic control, self‐liking, and self‐competence. It also assessed the relevance of these 4 types of self‐beliefs for personal job optimism among 268 Croatian college students. Results indicated that participants' career decision self‐efficacy and perceptions of their chances of finding jobs nationwide were significant predictors of personal job optimism. Furthermore, the influences of self‐competence and perceived academic control on personal job optimism were mediated by career decision self‐efficacy. These results extend previous research and may be informative for vocational guidance interventions.     

Influence of Proactive Personality on Career Self‐Efficacy

This study examined the relationship between proactive personality and career decision‐making self‐efficacy. In Study 1, the authors validated the Proactive Personality Scale–Korean Short Form, using the Rasch model with 315 participants, and found that fit statistics, point‐measure correlations, and item difficulty estimates satisfy the construct validity criterion. In Study 2, the authors administered the Proactive Personality Scale, Career Decision‐Making Self‐Efficacy Scale, and Career Search Self‐Efficacy Scale to 296 freshman and sophomore college students. Hierarchical regression analyses showed that proactive personality scores explain additional variance in both career decision‐making self‐efficacy and career search self‐efficacy scores. Implications for theory and practice are discussed.     

Mentoring as a Mediator or Moderator of the Association between Racial Discrimination and Coping Efficacy in Urban,Low‐Income Latina/o Youth

The aim of this study was to examine the associations among mentoring relationship quality (i.e., relational and instrumental quality), racial discrimination and coping efficacy with racial discrimination. Three social support models were tested, including the stress buffering, support mobilization, and support deterioration models. Participants were 257 urban, low‐income Latina/o high school students, who completed surveys in both 9th and 10th grades. While controlling for gender and coping efficacy with discrimination in 9th grade, results supported the social support deterioration model. Specifically, there was a significant indirect effect of racial discrimination in 9th grade on coping efficacy in 10th grade through instrumental mentoring quality. As racial discrimination increased, mentoring quality decreased and then coping efficacy decreased. We also found that more racial discrimination in 9th grade was significantly associated with lower coping efficacy in 10th grade, and higher instrumental mentoring quality in 9th grade was significantly associated with higher coping efficacy in 10th grade, while controlling for gender and coping efficacy in 9th grade. Implications and recommendations for future research are discussed.     

Enhancing treatment effectiveness through social modelling: A pilot study

Objective: Medical treatments take place in social contexts; however, little research has investigated how social modelling might influence treatment outcomes. This experimental pilot study investigated social modelling of treatment effectiveness and placebo treatment outcomes.

Design: Fifty-nine participants took part in the study, ostensibly examining the use of beta-blockers (actually placebos) for examination anxiety. Participants were randomly assigned to observe a female confederate report positive treatment effects (reduced heart rate, relaxed, calm) or feeling no different.

Main outcome measures: Heart rate, anxiety and blood pressure were assessed, as were symptoms and attributed side effects.

Results: Heart rate decreased significantly more in the social modelling compared to control condition, p = .027 (d = .63), and there were trends towards effects in the same direction for both anxiety, p = .097 (d = .46), and systolic blood pressure, p = .077 (d = .51). Significant pre-post placebo differences in heart rate, anxiety and diastolic blood pressure were found in the social modelling group, ps < .007 (ds = .77–1.37), but not the control condition, ps > .28 (ds = .09–.59).

Conclusions: Social observation of medication effectiveness enhanced placebo effectiveness in heart rate, and showed a trend towards enhancing treatment effectiveness in both anxiety and systolic blood pressure. Social modelling may have utility in enhancing the effectiveness of many active medical treatments.     

WHAT IS “SECULAR”? TECHNO‐SECULARISM AND SPIRITUALITY

Abstract. I argue that there is no “roaring reality of rampant secularism” with “technological application as its chief agent,” as claimed by John Caiazza (2005). Two phenomena, techno‐religion and a spirituality of technology, suggest a different picture of reality: Technology may be an alternative spirituality rather than an ally of a secularism that makes “nutcrackers of the soul” out of people who should be “dancers” (Nietzsche). An analysis of secularism and its manifold causes indicates that secularism is a fruit of both science and religion. The secular is a companion of religion rather than its enemy. Hence, I recommend a heuristic instead of an ontological use of the concept of secularism. In a technological age, religion is changing rather than being displaced. These changes are illustrated by the increase of private religiosity, megachurches, and cyber‐spirituality. Energized by the tension between finitude and creativity, technology shares in the marks of spirituality (Philip Hefner) and in the potential for good and evil. In this situation, fundamentalism and dogmatism in religion, science, and technology are a greater threat than secularism.     

关于临床决策问题

医生在临床工作中做出明确诊断,并据此给予有效的处理均属于决策过程。制定决策的整个过程,同时也是进行决策思维的过程。近年来高新技术的迅猛发展以及医疗费用急剧增加,使制定决策更加复杂。如何进行正确的决策思维,做出最切实可行的和最佳的决策,对避免决策的盲目性、局限性及惰性具有重要的现实意义。
