文化的商品与公共产品特性——兼与王晓升教授商榷

作为与政治、经济相并列的一个领域,文化已经成为现代社会系统中的重要组成部分.然而,对于文化在现代社会中的属性,在我国学术界一直存在着不同见解.     

The advantages,shortcomings, and existential issues of Zhuangzi’s use of images

Zhuangzi is considered a creative poet-philosopher because of his use of imaginative images. He used the imaginative images of his system to construct the world of the Dao. He left the essence of material things as they are to speak for the mystery of existence itself, and let them express both the state of and the dream for human freedom. Zhuangzi’s way of using images shows his own lack of the understanding about images, and his lack of adequate assessments. He used images in accord with his own personal preferences and fixed characteristics. He also had a tendency to equate the Dao which he experienced in his mind with the Dao itself. These shortcomings limit his improving and understanding of the Dao, so that his Dao failed to become more open to a wider existence.     

男女两性在文化震荡、心理健康及其关系中的差异比较

采用自编问卷对1555名30岁及以上被试受文化震荡的影响程度及其心理健康进行调查,分别探讨不同生活环境和环境相同但受教育程度不同的男女两性在两变量及其关系中的差异。结果表明:(1)总体上,男性报告的文化事件的主观影响明显比女性更积极,但其心理健康水平却明显低于女性;男女两性在文化震荡与心理健康之间均存在显著正相关,但具有不同特点。(2)不同生活环境和同一生活环境中不同受教育程度的男女两性在文化震荡、心理健康中均存在不同程度的差异;在这两变量间也均存在不同方面的显著正相关。     

Sadness and happiness are amplified in solitary listening to music

Previous studies have shown that music is a powerful means to convey affective states, but it remains unclear whether and how social context shape the intensity and quality of emotions perceived in music. Using a within-subject design, we studied this question in two experimental settings, i.e. when subjects were alone versus in company of others without direct social interaction or feedback. Non-vocal musical excerpts of the emotional qualities happiness or sadness were rated on arousal and valence dimensions. We found evidence for an amplification of perceived emotion in the solitary listening condition, i.e. happy music was rated as happier and more arousing when nobody else was around and, in an analogous manner, sad music was perceived as sadder. This difference might be explained by a shift of attention in the presence of others. The observed interaction of perceived emotion and social context did not differ for stimuli of different cultural origin.     

The Relationship Between Narcissism and Friendship Qualities in Adolescents: Gender as a Moderator

The present study explored the gender characteristics of narcissism as well as its relationship with friendship quality dimensions (i.e., trust & support, validation, and disclosure & communication) among 485 (197 boys and 288 girls) junior high and high school adolescents in a Southwest province in China. Significant gender differences were found, such that boys were more narcissistic than girls,while girls reported higher levels of friendship qualities, including validation and disclosure & communication. To examine gender moderations in the relationships between narcissism and friendship quality dimensions, multiple-group (by boys and girls) structural equation modeling were conducted. The results revealed the significant gender moderations in the associations between narcissism and friendship quality dimensions, while controlling for adolescent grade level. Specifically, narcissism significantly and positively related to the three aspects of friendship qualities (i.e., trust & support, validation, and disclosure & communication) among boys, but was not related to friendship quality among girls. Discussions are provided for an understanding of the current findings in the Chinese cultural context.     

Stress Among African American Emerging Adults: The Role of Family and Cultural Factors

The aim of this study was to examine the effects of family and cultural variables on stress among African American emerging adults. Data from this study was collected as part of a larger study that examined cultural, family, and contextual factors and smoking among African American youth in 5th, 8th, and 12th grades. Data were collected from high school seniors at the end of their 12th grade year and 6 months post high school. Multiple regression analyses were conducted to determine whether racial identity, family cohesion, and parental monitoring influence students’ perceived frequency of stress. Higher levels of racial identity were associated with more perceived stress. There were no significant main effects for either parental monitoring or family cohesion on stress. There were significant interactions between racial identity and parental monitoring and between parental monitoring and family cohesion. Study implications are discussed regarding the importance of stress reduction programs for African American emerging adults and for parents of these adults.     

School Connectedness and Problematic Internet Use in Adolescents: A Moderated Mediation Model of Deviant Peer Affiliation and Self-Control

Although a growing body of research documents the negative association between school connectedness and adolescent problematic Internet use (PIU), little is known about the mediating mechanism (i.e., how school connectedness relates to PIU?) and moderating mechanism (i.e., when the protection is most potent?) underlying this relation. The present study examined whether deviant peer affiliation mediated the relationship between school connectedness and PIU, and whether this mediating process was moderated by adolescent self-control. A total of 2,758 Chinese adolescents (46 % male; mean age?=?13.53 years, SD?=?1.06) from 10 middle schools completed anonymous questionnaires regarding school connectedness, deviant peer affiliation, self-control, and PIU. After controlling for gender, age, socioeconomic status, and parental attachment, it was found that the negative association between school connectedness and adolescent PIU was partially mediated by deviant peer affiliation. Moreover, this indirect link was stronger for adolescents with low self-control than for those with high self-control. These findings underscore the importance of integrating the social control theory and organism-environment interaction model to understand how and when school connectedness impacts adolescent PIU.     

Deposition-rate dependence of granular size distribution in Cu aggregate on liquid substrate studied by atomic force microscopy

In this article, we report an atomic force microscopy study on the microstructure and the deposition-rate dependence of granular size distribution in copper (Cu) ramified aggregates on a liquid substrate. This study shows that the ramified Cu aggregates are composed of Gaussian size distribution granules, which form immediately after the Cu atoms are deposited. The interesting phenomenon is that the mean diameter Φ_m of the granules exponentially decays and approaches a stable value Φ_c with an increase in the deposition rate f. The granular mean diameter Φ_m slightly changes with the time interval Δt during which the film is kept in the vacuum chamber, owing to the large diffusion coefficient of the Cu granules on the liquid substrates. The experimental behavior strongly depends on the properties of the liquid substrate.     

Temporal order perception of auditory stimuli is selectively modified by tonal and non-tonal language environments

The close relationship between temporal perception and speech processing is well established. The present study focused on the specific question whether the speech environment could influence temporal order perception in subjects whose language backgrounds are distinctively different, i.e., Chinese (tonal language) vs. Polish (non-tonal language). Temporal order thresholds were measured for both monaurally presented clicks and binaurally presented tone pairs. Whereas the click experiment showed similar order thresholds for the two language groups, the experiment with tone pairs resulted in different observations: while Chinese demonstrated better performance in discriminating the temporal order of two “close frequency” tone pairs (600 Hz and 1200 Hz), Polish subjects showed a reversed pattern, i.e., better performance for “distant frequency” tone pairs (400 Hz and 3000 Hz). These results indicate on the one hand a common temporal mechanism for perceiving the order of two monaurally presented stimuli, and on the other hand neuronal plasticity for perceiving the order of frequency-related auditory stimuli. We conclude that the auditory brain is modified with respect to temporal processing by long-term exposure to a tonal or a non-tonal language. As a consequence of such an exposure different cognitive modes of operation (analytic vs. holistic) are selected: the analytic mode is adopted for “distant frequency” tone pairs in Chinese and for “close frequency” tone pairs in Polish subjects, whereas the holistic mode is selected for “close frequency” tone pairs in Chinese and for “distant frequency” tone pairs in Polish subjects, reflecting a double dissociation of function.
