A field experiment testing frontline opinion leaders as change agents

On the basis of previous studies of source credibility and opinion leadership, the authors hypothesized that opinion leaders would serve as effective agents to promote positive attitudes toward a service-quality initiative and increase service-quality effectiveness. The service effectiveness of tellers before and after a service-quality leadership training program was rated by customers, supervisors, and the tellers themselves across 3 matched bank branches. Service effectiveness was rated significantly higher in a branch using opinion leaders as service-quality leaders compared with a branch using randomly selected frontline leaders. Tellers in the latter branch showed greater improvements in service effectiveness than did counterparts in a branch using no frontline service quality leaders. This difference between types of leaders appeared to be mediated by tellers' behavioral beliefs about the service-quality program.     

A mixture hierarchical model for response times and response accuracy

In real testing, examinees may manifest different types of test‐taking behaviours. In this paper we focus on two types that appear to be among the more frequently occurring behaviours – solution behaviour and rapid guessing behaviour. Rapid guessing usually happens in high‐stakes tests when there is insufficient time, and in low‐stakes tests when there is lack of effort. These two qualitatively different test‐taking behaviours, if ignored, will lead to violation of the local independence assumption and, as a result, yield biased item/person parameter estimation. We propose a mixture hierarchical model to account for differences among item responses and response time patterns arising from these two behaviours. The model is also able to identify the specific behaviour an examinee engages in when answering an item. A Monte Carlo expectation maximization algorithm is proposed for model calibration. A simulation study shows that the new model yields more accurate item and person parameter estimates than a non‐mixture model when the data indeed come from two types of behaviour. The model also fits real, high‐stakes test data better than a non‐mixture model, and therefore the new model can better identify the underlying test‐taking behaviour an examinee engages in on a certain item.     

Body dissatisfaction, maternal appraisal, and depressive symptoms in Hong Kong adolescents

Body dissatisfaction, its risk factors and association with depressed mood have been well investigated in the West. However, more studies are needed to examine further the relation between body dissatisfaction and depressive symptoms and the factors influencing body dissatisfaction in non-Western cultures. The present study examined in a sample of Hong Kong Chinese adolescents the relation between body dissatisfaction and depressive symptoms, and the relation of maternal appraisal of their adolescent's figure to the adolescent's body dissatisfaction and depressive symptoms. We obtained information from 379 boys and 254 girls about their body dissatisfaction and depressive symptoms. Their mothers provided information about their appraisal of their adolescent's body shape and size compared to ideal. Body dissatisfaction was related to depressive symptoms in girls (B = 2.58, p <.01), but not in boys (B = -0.08, p >.10). Negative maternal appraisal did not have direct effects on adolescents' depressive symptoms (B = 0.14, p =.75), but the association between negative maternal appraisal and body dissatisfaction was significantly stronger in adolescents whose ideal was smaller than they perceived themselves to be (B = 0.32, p <.01) than those whose ideal was larger than their own perception (B = 0.14, p < .01). Our findings suggest that maternal appraisal had indirect effects on mood, acting through adolescents' body dissatisfaction, and that body dissatisfaction may be a sex-specific risk factor for depression. This study points to the need for testing and adapting programs to reduce body dissatisfaction particularly in girls at risk for depression, and to raise mothers' awareness of the link between their negative appraisals and their adolescents' body dissatisfaction and depressive symptoms.     

农村卫生改革面临的深层次的矛盾和问题

对健康缺失阻碍农村经济发展没有清楚的认识,是制约农村卫生发展的重要因素.农村卫生纯属公共品范畴,理所当然是政府实现公共服务目标的基本职责.我国财政整体分配格局不合理,是农村卫生投入不足的基本原因.农村卫生保健制度一个非常突出的问题,是基本模式的选择,忽视关键制度的设计与调整.卫生院是医疗服务的提供者,是合作医疗保障制度的利益主体,同时又是合作医疗的组织者与管理者,不符合医疗保障制度的要求,同时也难以形成纠错的机制.     

How shared preferences in music create bonds between people: values as the missing link

How can shared music preferences create social bonds between people? A process model is developed in which music preferences as value-expressive attitudes create social bonds via conveyed value similarity. The musical bonding model links two research streams: (a) music preferences as indicators of similarity in value orientations and (b) similarity in value orientations leading to social attraction. Two laboratory experiments and one dyadic field study demonstrated that music can create interpersonal bonds between young people because music preferences can be cues for similar or dissimilar value orientations, with similarity in values then contributing to social attraction. One study tested and ruled out an alternative explanation (via personality similarity), illuminating the differential impact of perceived value similarity versus personality similarity on social attraction. Value similarity is the missing link in explaining the musical bonding phenomenon, which seems to hold for Western and non-Western samples and in experimental and natural settings.     

Target velocity effects on manual interception kinematics

Participants generated manual interception movements toward a target cursor that moved across a computer screen. The target reached its peak velocity either during the first third, at the midpoint, or during the last third of the movement. In Experiment 1 the view of the target was available for either the first 316, 633, 950, or 1267 ms, after which it disappeared. Results showed that for all viewing conditions, the timing of the interception velocity was related to the temporal properties of the target's trajectory. In Experiment 2, when the portion of the target trajectory that was viewed was reversed (such that participants did not see the first 316, 633, 950, or 1267 ms of the trajectory, but instead saw only the later portions of the trajectory), there was no clear relationship between the target trajectory and the timing of the aiming trajectory. These results suggest that participants use visual information early in the target's trajectory to form a representation of the target motion that is used to facilitate manual interception.     

Parental, peer, and teacher influences on the social behavior of Hong Kong Chinese adolescents

Intensive interviews and self-report questionnaires were used to investigate parental, peer, and teacher influences on the prosocial and antisocial behaviors of Hong Kong Chinese adolescents. Students came from 5 academically different high schools. Results indicated that perceived parental influence was positively associated with frequency of prosocial behavior and negatively associated with frequency of delinquent behavior. Students with good relationships with their parents and peers showed lower frequencies of antisocial behaviors than did students with bad relationships. Adolescents in different identity statuses (achievement, moratorium, foreclosure, diffusion; E. H. Erikson, 1968) showed different patterns of prosocial and antisocial behaviors. For example, adolescents in the identity achievement group exhibited high frequencies of prosocial behaviors and low frequencies of antisocial behaviors, but those in the identity moratorium group exhibited quite high frequencies of both prosocial and antisocial behaviors.     

Organization of visual short-term memory

The authors examined the organization of visual short-term memory (VSTM). Using a change-detection task, they reported that VSTM stores relational information between individual items. This relational processing is mediated by the organization of items into spatial configurations. The spatial configuration of visual objects is important for VSTM of spatial locations, colors, and shapes. When color VSTM is compared with location VSTM, spatial configuration plays an integral role because configuration is important for color VSTM, whereas color is not important for location VSTM. The authors also examined the role of attention and found that the formation of configuration is modulated by both top-down and bottom-up attentional factors. In summary, the authors proposed that VSTM stores the relational information of individual visual items on the basis of global spatial configuration.     

Psychological contract and organizational citizenship behavior in China: investigating generalizability and instrumentality

This study examined the generalizability of psychological contract forms observed in the West (D. M. Rousseau, 2000) to China. Using 2 independent samples, results confirmed the generalizability of 3 psychological contract forms: transactional, relational, and balanced. This study also examined the nature of relationships of psychological contracts with organizational citizenship behavior (OCB). In particular, this study explored the role of instrumentality as a mediating psychological process. The authors found evidence that instrumentality mediates the relationship of relational and balanced forms with OCB; however, the transactional contract form is directly related to OCB. The authors discuss the implications of these results for the meaning of psychological contracts and OCB in China and raise issues for future research.     

论儒家思想中的"人"与"自然"之关系:兼论其21世纪之启示

本文探讨儒家思想传统中“人”与“自然”之关系。本文先从比较文化史视野,析论中国思维方式之特质在于“联系性思维方式”。本文指出,儒家思想传统以“联系性思维方式”为基础,强调“人”与“自然”之间是一种相即相融并互相渗透的关系。“自然”是“人”的创生者,“人”也是“自然”的参与者。儒家思想家主张“人”与“自然”之间具有连续性与一体性之关系。这两种关系之所以可能,其基础正在于人与宇宙万物都以生生不已的仁德为其本性。“仁”既内在于每个人的心性之中,又超越于每个个体之上,成为宇宙万物之共同质素。而儒家思想中“人”与“自然”之连续性与一体观的建立与发展,正是以人“心”之自觉为其基础。
