潜变量交互效应模型标准化估计中的检验问题

讨论了潜变量交互效应模型是否能直接用统计软件输出的原始估计的t值对模型的标准化估计进行检验的问题,详细介绍了标准化估计的t值计算及其难点,用Bootstrap方法算出标准化估计的标准误和相应的t值（记为t_bs）,并将其与原始估计的t值比较.结果发现,当原始估计t值超过3时,无论用t值还是用t_ bs检验,结果都是显著,即可以使用t值进行检验.而当t值不超过3时,与t_bs很接近,也可以用t值检验,但t值在临界值附近（例如1.5 ～2.5）时,最好还是使用Bootstrap法计算t_bs进行检验.

Social identity gratifications of social network sites and their impact on collective action participation

Collective action has been studied by social psychologists for over a century. Social network sites such as Facebook have further extended the ability of individuals to instigate social, political and organizational change, and provide a new context in which to study collective action. Drawing on social identity theory (SIT), self‐categorization theory (SCT) and uses and gratifications theory (UGT), this study explores the role of individuals’ group identification, social identity gratifications (SIG) and Facebook group use intensity on their willingness to participate in collective actions instigated through a Facebook group. Members of a Facebook group representing a cause against management completed an online survey (N = 406). Factor analyses reveal that motivations based on psychological affiliation with the group explained the most variance for Facebook group use. Moreover, compared to Facebook group use intensity, SIG were the stronger mediator between group identification and willingness to participate in collective action. The study demonstrates the utility of blending concepts from SIT, SCT and UGT to explore how socially motivated uses of the media can predict collective actions.     

Assessment of Li 利 in the Mencius and the Mozi

The attitude toward li 利 is often identified as a key difference between the Mencius 孟子 and the Mozi 墨子. A common view is that for the Mencius, rightness (yi 義) and li are incompatible; but for the Mozi they are not necessarily so. In this paper I argue that the Mencius and the Mozi are in broad agreement on the issue of li, and their attitudes toward li are not as different as may seem at first glance. If we take a finer-grained understanding of li in two ways, namely the self-regarding li and the other-regarding li, then both the Mencius and the Mozi would criticize the former but encourage the latter. The term li in the Mencius has a range of meanings, and it is not clear whether the Mencius actually opposes all li-pursuing activities. Mencius would agree with Mozi that, at least in some cases, one is obligated to seek li for others. Furthermore, despite their criticism of self-regarding li, both Mencius and Mozi allow that in some cases it is morally permissible to act from the motive of self-regarding li, as long as this motive coexists with the motive of rightness. That is, self-regarding li and rightness are not always mutually exclusive, even for Mencius, who seems to be more critical of li.     

Package size and perceived quality: The intervening role of unit price perceptions

This research examines how package size can influence quality judgments for packaged goods, and also identifies a price-based mechanism for the observed size–quality relationship. Results from several studies show that a product in a smaller package is rated more favorably than the equivalent product in a larger package. Further, this effect is due to the smaller package being associated with a higher unit price (despite having a lower overall price), which suggests that unit price information is more diagnostic than overall price information when forming judgments of product quality. We also find a theoretically-derived reversal of this effect under conditions in which the greater diagnosticity of unit price is overwhelmed by its lower ease of use. Namely, when overall price is the only explicitly-provided price cue and consumers are too distracted to estimate unit price, a larger package is now rated as being better. Finally, two concluding studies examine the downstream consequences of changes in package size, building off our basic conceptualization to document effects on product choice as well as consumption experience.     

The effect of visual complexity and word frequency on eye movements during Chinese reading

Eye movements of native Chinese readers were monitored when they read sentences containing single-character target words orthogonally manipulated for frequency and visual complexity (number of strokes). Both factors yielded strong main effects on skipping probability but no interaction, with readers skipping visually simple and high frequency words more often. However, an interaction between frequency and complexity was observed on the fixation times on the target words with longer fixations for the low frequency, visually complex words. The results demonstrate that visual complexity and frequency have independent influences on saccadic targeting behaviour during Chinese reading but jointly influence fixation durations and that these two factors differently impact fixation durations and saccade targeting during reading.     

论“价值排序”研究的三个主要问题

价值排序是个复杂的社会现实问题,也是伦理学研究中的一个重要理论问题。一般说来,在道德生活中每个道德主体都有自己的核心价值以及自己所认定的价值排序表,但这些价值原则的序列不是一层不变的,会相互碰撞和冲突,产生伦理风险和道德困境。当今关于价值排序的研究转向主要体现在研究对象的确定、研究进路的探讨和研究方法的创新上。本文通过对两本伦理学专业期刊的统计研究,分析了价值排序问题的国内外研究现状,提出以"伦理风险"作为研究进路,以情景主义和透视主义为主要研究方法,以期为价值排序问题的研究提供新的视角和可借鉴的路径。     

动作疗法在灾后心理康复中的运用

在四川经历了汶川大地震后两年,青海又发生了玉树地震。地震灾害不仅对灾区幸存者造成了身体上的伤害,让人们失去家园和亲人,在心理上也给他们造成了严重的创伤。因此,对于这类人群的灾后心理康复治疗尤为重要。然而,幸存者心理的康复,单纯依靠心理辅导和治疗是不够的,而肢体上的运动能够起到缓解心理症状的良好效果。动作疗法就是一种行之有效的疗法。本文将介绍动作疗法在灾后心理康复的治疗中的运用,并提出具有针对性的动作疗法的措施。     

Personal and impersonal stimuli differentially engage brain networks during moral reasoning

Moral decision making has recently attracted considerable attention as a core feature of all human endeavors. Previous functional magnetic resonance imaging studies about moral judgment have identified brain areas associated with cognitive or emotional engagement. Here, we applied graph theory-based network analysis of event-related potentials during moral decision making to reveal the personal/impersonal distinction in the organization of functional connectivity. Our results indicated that the personal task had more larger long-range connections involved in frontal regions and the right hemisphere, and higher network efficiency of some frontal electrodes such as F2 than the impersonal. These might be related to brain resource reorganization contributing to efficient conflict resolution. These findings provide new insights into neural mechanisms of moral dilemmas.
