Social Trait Information in Deep Convolutional Neural Networks Trained for Face Identification

Faces provide information about a person's identity, as well as their sex, age, and ethnicity. People also infer social and personality traits from the face — judgments that can have important societal and personal consequences. In recent years, deep convolutional neural networks (DCNNs) have proven adept at representing the identity of a face from images that vary widely in viewpoint, illumination, expression, and appearance. These algorithms are modeled on the primate visual cortex and consist of multiple processing layers of simulated neurons. Here, we examined whether a DCNN trained for face identification also retains a representation of the information in faces that supports social‐trait inferences. Participants rated male and female faces on a diverse set of 18 personality traits. Linear classifiers were trained with cross validation to predict human‐assigned trait ratings from the 512 dimensional representations of faces that emerged at the top‐layer of a DCNN trained for face identification. The network was trained with 494,414 images of 10,575 identities and consisted of seven layers and 19.8 million parameters. The top‐level DCNN features produced by the network predicted the human‐assigned social trait profiles with good accuracy. Human‐assigned ratings for the individual traits were also predicted accurately. We conclude that the face representations that emerge from DCNNs retain facial information that goes beyond the strict limits of their training.

同一广告,不同视点:公益广告关注点的性别差异

在广告中使用代言人成为越来越常用的手段。传统异性相吸的观点认为,受众更关注异性代言人的信息,而近期研究则表明存在同性偏差效应,即受众更关注同性代言人信息。本研究通过眼动追踪技术记录了男、女受众在观看禁烟公益广告期间的眼动特征,通过比较受众的首次关注潜伏期和总注视时间两个指标,首次从眼动特征上证实了同性偏差效应。本研究拓展了同性偏差效应的适用领域,对公益广告的设计具有指导意义。     

The cross-lagged relationship between interpersonal forgiveness and depression symptoms in China

This study investigated the relationship between the process of forgiveness and depressive symptoms in China. A total of 116 college students who had experienced an interpersonal transgression “within the past week” were selected to perform the tracking measurements at 2-week intervals. Cross-lagged models showed that the victim's depressive symptoms were related to increasing revenge and avoidance motivations as well as decreased benevolence motivation; however, the revenge, avoidance, and benevolence motivations of the victims did not predict subsequent changes in depressive symptoms. These results confirm that the presence of depressive symptoms is a predictor of the reduced interpersonal forgiveness, and the alleviation of individuals' depressive symptoms plays a protective role in the adaptive process of interpersonal relationships.     

弥勒信仰衰落原因简论

弥勒净土信仰在南北朝时期非常兴盛,到隋唐以后逐渐衰落.其衰落的内在原因,主要是在弥勒净土和弥陀净土的选择上,信众更倾向于后者.其次·弥勒净土后继乏人而弥陀净土却人才辈出,以及以弥勒为号召的民众起义所带来的负面影响,是弥勒信仰衰落的另一在原因.     

云南傣族封建法律文明源于外来宗教的影响

少数民族宗教对社会法律影响很大,就南传上座部佛教来说,其深刻影响了云南傣族封建法律的各个方面,使傣族封建法律形成了自己的特色,无论就其内容、程序,还是其司法制度、操作手法都被抹上一层厚厚的宗教色彩.南传上座部佛教对傣族封建法律的影响是积极的、上进的,致使傣族封建法律文化、乃至傣族社会文化具有较高的文明化程度.

针灸治疗周围性面瘫随机对照研究的文献分析

遵循循证医学评价文献的原则,在中国生物医学文献数据库、CNKI等数据库全面检索2002—2006年间的相关文献并进行计量学评价分析。共检索出文献1284篇,其中RCT文献共有169篇,按照循证医学评价文献的原则及方法,从研究对象、随机分配方法、对照措施、盲法采用情况等多个方面进行分析评价。2002—2006五年间报道的RCT数量比从建国到2000年报道的RCT数量多,但仍需进一步改善文献质量。
