应激对中国地鼠糖尿病发生的影响

研究实验性应激、情绪性、笼架水平在中国地鼠糖尿病发生中的作用强度及其交互作用,以确定中国地鼠糖尿病发生危险因素。结果表明实验性应激(震动、旋转合并限制)能促使中国地鼠血糖水平显著升高,糖尿病发病率增加,发病年龄提前;高情绪性中国地鼠,随着实验时间延长,其发病率也逐渐升高,并稳定在一定水平;析因方差分析提示,实验性应激与动物情绪性的交互作用对实验后中国地鼠的血糖变化起主要作用。     

Effects of retention intervals on the magnitude of optokinetic rotation-induced taste aversions.

This study investigated the effects of different retention intervals on the magnitude of optokinetic rotation-induced conditioned taste aversions in humans. Two experiments were conducted. In Exp. 1, 20 subjects were divided into two groups, a CS-UCS group in which drinking soybean milk was paired with optokinetic rotation-induced gastric illness and a CS-Only group in which drinking soybean milk was not paired with optokinetic rotation. Analysis indicated that two days after pairing soybean milk drinking with optokinetic rotation, the subjects in the CS-UCS group had significantly reduced palatability ratings of soybean milk and lower consumption of soybean milk than those in the CS-Only group. In Exp. 2, 40 subjects were divided into four CS-UCS groups with 1-day, 3-day, 5 day, and 10-day retention intervals between the session of pairing soybean milk with optokinetic rotation and the session of retasting soybean milk. Analysis yielded no significant differences among four groups on palatability of soybean milk and consumption of soybean milk in the retasting session. It is concluded that optokinetic rotation is an effective unconditioned stimulus for conditioned taste aversions formation and that the aversion has a retention period of at least 10 days.     

理想情感及其影响的跨文化差异

理想情感是人们期望获得的情感状态。情感评估理论认为文化对理想情感的塑造有着重要影响,主要的影响途径有文化体验、文化价值观和社会文化变化。理想情感对个体会产生具有文化特异性的影响,主要会影响个体的偏好及选择行为、混合情绪体验、身心健康和社会认知决策。理想情感研究未来发展可以着眼于4个方向:使用纵向视角研究理想情感,进一步探索理想情感的前因变量,打造适合中国文化的心理健康标准和通过认识理想情感来消除文化隔阂。     

Bridging the Gap: How Supervisors’ Perceptions of Guanxi HRM Practices Influence Subordinates’ Work Engagement

This study aims to provide new insights into the relationship between supervisors' perceptions of guanxi human resource management (HRM) practices and their subordinates' work engagement. We used a three time‐lagged sample from 45 work groups and 205 employees in a state‐owned organisation (Study 1) and cross‐sectional data from 101 work groups and 413 employees in 101 different organisations (Study 2) to test our hypotheses. The results revealed that supervisors' perceptions of guanxi HRM practices were positively related to subordinates' perceptions of guanxi HRM practices, which, in turn, negatively affected subordinates' work engagement. This indirect effect was stronger when group power distance was low or when individual power distance orientation was low.     

Long-term follow-up of physical activity behavior in older adults.

OBJECTIVE: To examine the contribution of social-cognitive factors (self-efficacy and affect) in predicting long-term physical activity in a sample of older adults (N=174). DESIGN: A prospective design assessed physical activity and psychosocial variables at 2 and 5 years following a 6-month randomized, controlled exercise trial. MAIN OUTCOME MEASURES: The primary outcome variable was self-reported physical activity, with previous behavior, self-efficacy, and affect assessed as determinants of physical activity. RESULTS: Covariance modeling analyses indicated that physical activity at Year 2 was the strongest predictor of physical activity at 5-year follow-up. Both self-efficacy and affect at Year 2 were also associated with physical activity at Year 5, as was original treatment condition. Variables accounted for 35% of the variance in Year 5 activity. CONCLUSION: Older adults with higher levels of physical activity, more positive affect, and higher self-efficacy at Year 2 were more likely to continue to be active at Year 5. This study is one of the longest follow-ups of exercise behavior in older adults and has implications for structuring environments to maximize the maintenance of physical activity.     

犹太科学运动的政治和民族动因

19世纪上半叶,在犹太学领域兴起的科学运动是在欧洲民族主义普遍发展、现代反犹主义加剧的情况下进行的,它的背后潜藏着深厚政治和民族动因。德意志民族主义一方面强化了反犹主义,使得犹太知识精英在文化界特别是大学面临困境,犹太人从痛苦的经历中感受了一种前所未有的民族存在意识。作为一种正面力量,德意志民族浪漫主义思潮也激发并强化了犹太民族自信心,它与启蒙时代的理性主义汇合,为科学犹太学提供了动力。因此,犹太科学运动可以被看作是犹太民族史上的一场文化复兴运动。     

肢体伤残者心理康复的试探性研究

三年来,根据接待配装假肢及康复治疗伤残病人的实际情况,我们选择了感觉、知觉和记忆三个项目,进行了测定,即:(1)伤残部位和对应部位的两点阈值测定;(2)装戴假手后提重差别阈限的测定;(3)再认能力测定。结果表明,这些测定对伤残病人的康复治疗和心理评定都有一定的参考价值。     

Tracing enhances problem-solving transfer,but without effects on intrinsic or extraneous cognitive load

People can make pointing gestures and tracing actions with the index finger with little or no conscious effort. From the perspective of cognitive load theory, such “biologically primary” gestures and actions might help people learn “biologically secondary” concepts and skills requiring extended cognitive effort, such as reading, science, or mathematics. Studies on tracing or tracing and pointing have yielded mixed findings regarding hypothesized effects on intrinsic and extraneous cognitive load. The present study investigated whether computer-based instructions to trace elements of worked examples on angle relationships would affect school students' (N = 106) self-reports of intrinsic and extraneous cognitive load, as well as problem-solving transfer test performance. The tracing effect on transfer posttests seen in prior studies was replicated, but cognitive load hypotheses were not supported. Implications for educational practice and future research are discussed.     

信息生产力初探

一、信息生产力的特征和涵义科学技术是第一生产力，电子信息技术作为当今高科技的重要内容，它成为生产力的一种新类型，自然是顺理成章的。信息生产力是在电子信息产业的发展中产生的，其外延和内涵都有相对独立的特点。从生产力的要素来看，劳动者已从蓝领和白领转向了...
