高一学生应对灵活性及其影响因素的研究

本研究采用问卷调查和实验室任务相结合的方法,对59名高一学生进行一个月的跟踪调查,对结果进行聚类分析,旨在探寻高一学生在应对灵活性方面表现出的不同风格,同时从自我效能感、社会支持两方面探讨影响高一学生应对灵活性的主观和客观因素。研究结果表明:(1)聚类分析得到高一学生应对灵活性的四种类型:应对灵活型,积极不灵活型,消极不灵活型和积极不一致型;(2)应对灵活型和积极不灵活型被试的控制感显著高于消极不灵活型和积极不一致型;策略选择方面,积极不灵活型、积极不一致型倾向于使用问题焦点应对,应对灵活型、消极不灵活型倾向于使用情绪焦点应对;(3)自我效能感和社会支持在一定程度上可对应对灵活性类型产生预测作用,应对灵活型学生的自我效能感和对社会支持的利用度明显高于其他三类学生。研究结果有助于我们深入了解高中学生的适应问题。     

Contextual effects on number-time interaction

Time perception has long been known to be affected by numerical representations. Recent studies further demonstrate that when participants estimate the duration of Arabic numbers, number magnitude, though task-irrelevant, biases duration judgment to produce underestimation for smaller numbers and overestimation for larger numbers. Such effects were found in the present study to be significantly reduced when a weight unit gram was suffixed to the numbers rendering the mental magnitude differences between different numbers less distinctive. The effects were enhanced when a different unit kilogram was suffixed to the numbers enlarging the perceived magnitude differences between different numbers. The results indicate that effects of number magnitude on duration estimation should not be attributed to the mathematical differences between numbers but to how the numbers are perceived to differ from each other in magnitude in specific contexts when they denote concrete items. The results also provide new evidence for the theoretical proposal of a common generalized magnitude system and indicate that the system must be extended to include other action-oriented magnitudes, such as weight.     

Discriminant Analysis Using Mixed Continuous,Dichotomous, and Ordered Categorical Variables

This article proposes an intuitive approach for predictive discriminant analysis with mixed continuous, dichotomous, and ordered categorical variables that are defined via an underlying multivariate normal distribution with a threshold specification. The classification rule is based on the comparison of the observed data logarithm probability density functions. To reduce the computational burden, the analysis is conducted in the context of a confirmatory factor analysis model with independent error measurements. Identification of the dichotomous and ordered categorical variables is discussed. Results are obtained by implementations of a Monte Carlo expectation maximization (MCEM)algorithm and a path sampling procedure. Probabilities of misclassification are estimated via the idea of the “jackknife” method. A real example is given to illustrate the proposed method.     

Neural control of fundamental frequency rise and fall in Mandarin tones

The neural mechanisms used in tone rises and falls in Mandarin were investigated. Nine participants were scanned while they named one-character pictures that required rising or falling tone responses in Mandarin: the left insula and right putamen showed stronger activation between rising and falling tones; the left brainstem showed weaker activation between rising and falling tones. Connectivity analysis showed that the significant projection from the laryngeal motor cortex to the brainstem which was present in rising tones was absent in falling tones. Additionally, there was a significant difference between the connection from the insula to the laryngeal motor cortex which was negative in rising tones but positive in falling tones. These results suggest that the significant projection from the laryngeal motor cortex to the brainstem used in rising tones was not active in falling tones. The connection from the left insula to the laryngeal motor cortex that differs between rising and falling tones may control whether the rise mechanism is active or not.     

Family mastery enhances work engagement in Chinese nurses: A cross-lagged analysis

Based on Greenhaus and Powell's (2006) theory of work–family enrichment and the job demands-resources (JD-R) model of work engagement (Bakker & Demerouti, 2008), this study focused on the family-to-work enrichment process by investigating the effect of family mastery on work engagement in a Chinese context. A sample of 279 Chinese female nurses completed questionnaires in a two-wave longitudinal survey. With a cross–lagged analysis, the results indicated that family mastery at Time 1 had a significant positive effect on work engagement at Time 2. Furthermore, the relationship between family mastery and work engagement was stronger in a context of high (vs. low) job demand. These findings suggested that resource generated in family could directly help people stay engaged in the workplace, particularly under stressful working conditions. Our findings have expanded the JD-R model of work engagement and bridged it with theory of work–family enrichment. Implications for theory and practices are discussed.     

Examination of a perceived cost model of employees' negative feedback-seeking behavior

The present study extends the feedback-seeking behavior literature by investigating how supervisor-related antecedents (i.e., supervisors' expert power, reflected appraisals of supervisors, and supervisors' emotional intelligence) influence subordinates' negative feedback-seeking behavior (NFSB) through different cost/value perceptions (i.e., expectancy value, self-presentation cost, and ego cost). Using data collected from 216 supervisor-subordinate dyads from various industries in Taiwan, we employ structural equation modeling analysis to test our hypotheses. The results show that expectancy value mediates the relationship between supervisor expert power and subordinates' NFSB. Moreover, self-presentation cost mediates the relationship between reflected appraisals of supervisors' and subordinates' NFSB. Theoretical and practical implications of this study are also discussed.     

楚竹书《孔子诗论》“类序”辨析

通过对楚竹书《孔子诗论》的分析,结合对《诗经》文本形成过程的探讨,得出《诗经》之部类及其类序为《风》、《小雅》、《大雅》、《颂》的结论,同时厘清孔子、《孔子诗论》和《毛诗》在文本方面的关系。《诗经》的结集经历了一个过程,其分类由来已久;未曾更改。《诗》“类序”的形成也具有一定的历史性,是在《诗》文本编辑过程中自然形成的。孔子在整理《诗经》的过程中并不存在一个前提性的“编序”原则,所谓孔子“删诗”,只是对诗篇做些必要的一般性古籍整理而已。至于出土文献《孔子诗论》中偶尔出现的颠倒《诗》“类序”的论述亦属正常,并不能说明孔子曾编有与传统《诗》“类序”相反的文本,也不能否定《毛诗》文本具有一定的历史延续性,更不能由此说明《孔子诗论》中出现“类序颠倒”具有更为不可测知的寓意。     

Pathogens promote matrilocal family ties and the copying of foreign religions

Within the same pathogen-stress framework as proposed by Fincher & Thornhill (F&T), we argue further that pathogen stress promotes matrilocal rather than patrilocal family ties which, in turn, slow down the process of modernity; and that pathogen stress promotes social learning or copying, including the adoption of foreign religions.     

晚明清初儒学转型中的性命论演进

作为儒学研究的重要内容,性命论在晚明清初儒学转型进程中呈现极为复杂的发展形态。于晚明三教合流趋势中,部分儒者所持性命论主张对佛、道思想具有极高程度的包容力,由此引发大规模的"正统""异端"之争;于心学修正思潮中,东林学派及之后刘宗周对传统儒学"性命"之说秉持更为严肃的坚守态度,如此,"性命"的客观义、超越义得到强调;清初,在形上学渐趋没落之际,部分儒学人士对"性命"的诠释多从"材质之性"谈起——侧重对现实人生延续及发展等诉求的考量,此时性命论"天"字义渐次流失,"命"的世俗义得到落实。
