绝对与人类自由--谢林《自由论》探析

本文集中探讨谢林的《自由论》及其在西方哲学史上的意义,作者在指出这部著作不足的同时,充分肯定谢林对自由及与之相关问题的发问,并认为这是近现代西方哲学对人类自身命运的一次重要思考。     

风险情景中参照点与管理者认知特征

采用问卷测量的方法探讨风险情景以及个性特征对个体风险倾向的影响。结果显示：(1)成就动机的两个成分,即争取成功与回避失败能够分别预测个体在风险情景中的风险倾向与认知特征;争取成功动机对预测个体机会认知更敏感,而回避失败动机对预测威胁认知更有效。(2)回避失败动机是区分个体风险倾向的关键变量,个体在风险情景中的风险倾向取决于个体回避失败动机的强弱。(3)实验证实了当以“成功”为参照点时,回避失败倾向低的个体,在获益情景中更冒险而在损失情景中更保守;相反,回避失败倾向高的个体,在损失情景中更冒险而在获益情景中更保守。研究表明,结合人格和情景两类变量探讨个体风险倾向的反应模式能够更准确地描述个体行为倾向及其认知特征。这一结论提供了一个可能的思路来解释P理论与刻板模式之间的争执。另外,企业与学生样本在数据的总体趋势上存在相当多的一致性,但在细节上仍然存在差异,因此以学生样本数据进行推论时须要特别谨慎。     

The development of social aggression and physical aggression: A narrative analysis of interpersonal conflicts

Using conflict narratives reported by children and adolescents, this study investigated the development and social functions of social aggression in comparison to physical aggression. A total of 510 participants in two cohorts of a longitudinal study were involved (116 girls and 104 boys from Grade 4 and155 girls and 135 boys from Grade 7). Patterns of social aggression and physical aggression were identified based on interview reports in the first year of the study. Results showed that a triadic structure of social relationship was often reported in conflicts where social aggression was employed, whereas a dyadic structure was reported in conflicts involving physical aggression. Girls tended to use social aggression against girls, whereas boys tended to use physical aggression against boys. Children and adolescents who were central in peer social networks were more likely to employ social aggression than those who were peripheral in the networks. Social aggression was not reliably linked to concurrent or future problematic adjustment. Physical aggression, however, was not related to network centrality but was linked to concurrent and future maladjustment (e.g., low academic competence and school dropout). Aggr.

Development of brain functional connectivity and its relation to infant sustained attention in the first year of life

The study of brain functional connectivity is crucial to understanding the neural mechanisms underlying the improved behavioral performance and amplified ERP responses observed during infant sustained attention. Previous investigations on the development of functional brain connectivity during infancy are primarily confined to the use of functional and structural MRI techniques. The current study examined the relation between infant sustained attention and brain functional connectivity and their development during infancy with high‐density EEG recordings. Fifty‐nine infants were tested at 6 (N = 15), 8 (N =14), 10 (N = 17), and 12 (N = 13) months. Infant sustained attention was defined by measuring infant heart rate changes during infants’ looking. Functional connectivity was estimated from the electrodes on the scalp and with reconstructed cortical source activities in brain regions. It was found that infant sustained attention was accompanied by attenuated functional connectivity in the dorsal attention and default mode networks in the alpha band. Graph theory analyses showed that there was an increase in path length and a decrease in clustering coefficient during infant sustained attention. The functional connectivity within the visual, somatosensory, dorsal attention, and ventral attention networks and graph theory measures of path length and clustering coefficient were found to increase with age. These findings suggest that infant sustained attention is accompanied by distinct patterns of brain functional connectivity. The current findings also suggest the rapid development of functional connectivity in brain networks during infancy.     

The structure of trust as a reflection of culture and institutional power structure: Evidence from four East Asian societies

Using the Global Trust Inventory, an integrated measure of trust toward 21 relationships and institutions, the structure of trust was explored in four East Asian societies (Mainland China, Japan, South Korea, and Taiwan). The Western model, in which trust is distributed among seven factors representing different branches of society, did not generalize to these East Asian societies, perhaps due to differences in culture and institutional power structures. Instead, two unique structures of trust were identified. Mainland China had a top‐down structure of trust (the China model), in which trust is hierarchically separated between the central government and subordinate implementing bodies. The other three democratic East Asian societies shared a hybrid structure of trust (the Democratic East Asian model) that has a degree of similarity to both the China model and the Western model. Having established two similar, but still distinct models, a cross‐cultural comparison was made on the proportions of trust profiles generated by latent profile analysis. Mainland China had the largest proportion of people with a high propensity to trust, followed by Japan and South Korea, and Taiwan was the least trusting. Implications of the structure of trust and this alternative approach to conducting cross‐cultural comparisons are discussed.     

Claiming best or better? The effect of target brand's and competitor's puffery on holistic and analytic thinkers

Previous empirical studies have yielded contradictory results about how consumers react to puffed claims in advertisements. This study addresses this issue by considering how consumers' thinking style and competitors' puffery interact to influence consumers' brand attitude in terms of product puffery. Drawing upon experiments using fictitious and real brand names, three studies provide converging evidence that holistic thinkers will form a more positive brand attitude when exposed to the target brand's low‐puffery (vs. no puffery or high puffery) claims. In contrast, analytic thinkers are less sensitive to puffery, and their brand attitude will not change. Further, holistic thinkers are more sensitive to the presence of competitor's puffery. Holistic thinkers exposed to competitor's high‐puffery (vs. low) claims form a more positive brand attitude toward the target brand. For analytic thinkers, competitor's puffery level will not significantly affect their attitude toward the target brand. Our findings shed fresh light on the inconclusive results of prior studies and offer practical implications for marketing puffery.     

Self–other differences in change predictions

Individuals live in a changing world in which they predict future events based on past trends. Every event changes between two extremes (e.g., increases and decreases, successes and failures, and peaks and bottoms). People will anticipate changes if they can see the correlation between two extremes. This study investigates whether predictions about changes differ when individuals make predictions about events regarding themselves and others. Based on construal level theory, we hypothesized and found that people who made predictions for others anticipated more changes between two extremes than those who made predictions for themselves. However, self–other differences had boundary conditions. These differences were found in past trends without reversals but not in those with reversals. These results provide novel insights into change predictions.     

Effect of deep cryogenic treatment on carbon segregation in Cr8Mo2SiV tool steel during tempering

Carbon segregation in Cr8Mo2SiV tool steel after common heat treatment (CHT) and deep cryogenic treatment (DCT) has been investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM) extraction replica and three-dimensional atom probe (3DAP) tests. The XRD results show that most of the retained austenite transformed to martensite after DCT. The TEM results confirm the transformation of blocky retained austenite to twin martensite during DCT. The 3DAP results reveal the segregation of carbon atoms and the maximum carbon fraction in carbon-rich regions increases after DCT. The peak carbon concentration in carbon-rich regions of SDC99 steel after CHT and DCT are 8 at. % and 15 at. %, respectively. The segregated carbon atoms grew into nuclei for nanoscale carbides precipitation on subsequent tempering.
