Transformational Leadership and Organisational Citizenship Behaviour: A Moderated Mediation Model of Leader‐Member‐Exchange and Subordinates' Gender

Transformational leadership (TL) enhances follower Organizational Citizenship Behavior (OCB) as mediated by leader‐member exchange (LMX). However, the strength of the positive associations among TL, LMX and OCB is subject to significant variability. Accordingly, we draw on several theories (self‐identity, role congruency, self‐concept, and social exchange) to propose that followers' gender moderates the relationships between all three of these variables. We argue differences in societal expectations and/or underlying motivation combine to make leadership of lesser importance to OCB among females than males. Using 202 supervisor‐subordinate dyads from Taiwan, a moderated mediation model of TL‐LMX‐OCB, with subordinate gender as a moderator, was tested. As hypothesised, each of the positive associations among TL, LMX and OCB were weaker for females than for males, thus accounting for some of the variability in the strength of the associations typically observed. Relatedly, although LMX fully mediated the TL‐OCB relationship in the entire sample, this effect was not observed among female subordinates. Further research is required to assess the degree to which these findings apply beyond the Confucian Asian societal cluster.     

拉图尔的科学哲学观——在巴黎对拉图尔的专访

传统的科学哲学研究经过20世纪的蓬勃发展之后,目前,正面临着新的挑战与机遇。一方面,代表科学哲学研究主流路径的科学实在论与反实在论的论证方式,遇到了在原有框架内难以解决的内在矛盾,陷入了无法自救的困境;另一方面,随着一批人文学者运用人类学的方法和社会学的术语,对科学事实、科学实验、科学知识等基本概念的重新阐述,以及对科学知识产生的理性基础和科学家的认知活动的客观性前提的根本质疑,强烈要求更新传统的科学哲学研究模式。在这种背景下,为了全面了解西方科学哲学的研究现状与发展趋势,有选择性地对著名的科学哲学家与科学知识社会学家进行系列专访,是一件非常有意义的事情。     

Psychosocial Factors Predicting SARS-Preventive Behaviors in Four Major SARS-Affected Regions

This multinational study examined intended and actual adoption of SARS-preventive behaviors in major SARS-affected regions: Guangdong (China), Hong Kong, Singapore, and Toronto (Canada). The theory of reasoned action (TRA) and the theory of planned behavior (TPB) were adopted as theoretical frameworks. A measure was constructed to assess attitude, subjective norm, perceived behavioral control (PBC), knowledge of SARS, and SARS-preventive behaviors. Seventy-five working adults were recruited from each region. They completed the new measure in an initial study, and reported their actual behaviors 2 weeks later. Results provided cross-cultural generalizability of the TRA by showing that attitude and subject norm predicted SARS-preventive behaviors for all the groups. PBC was a statistically significant predictor for all participants except those from Guangdong, indicating that the TPB is applicable only to people from Hong Kong, Singapore, and Toronto. Knowledge of SARS also was found to be an independent predictor.     

学业自我概念及其与学业成绩关系的研究述评

自1976年Shavelson将自我概念区分为学业自我概念和非学业自我概念以来,教育心理学家对学业自我概念的结构及学业自我概念与学业成绩的关系进行了广泛研究。本文在阐述学业自我概念的多侧面结构和等级结构模型的基础上,着重探讨了学业自我概念与学业成绩的关系,并对学业自我概念的研究进行了展望。     

Applicant impression management in job interview: The moderating role of interviewer affectivity

In light of the organizational need to obtain talented personnel, an appropriate evaluation of applicant behaviour in the selection interview is crucial. Extending past research on applicant use of impression management (IM) tactics, this study examines the effects of a broad set of IM tactics in a field setting, and also investigates the moderating roles of two rarely tested interviewer characteristics: interviewer positive affectivity (PA) and negative affectivity (NA). Due to the nested nature of the data, consisting of 142 job applicants and 33 interviewers, we adopt hierarchical linear modelling (HLM) to examine the proposed hypotheses. The results indicate that three IM tactics (self‐focused IM, SFIM; other‐focused IM, OFIM; and non‐verbal IM, NVIM) are significantly positively related to interviewer evaluations. Furthermore, interviewer PA appears to strengthen the positive effects of SFIM tactics on interviewer evaluations, while the effects of NVIM tactics may be weaker when interviewers are high in NA. In addition, these findings suggest the importance of interviewer trait affectivity in explaining interviewer's decision‐making variability, which may lead to low inter‐rater reliability and in turn restrict the level of achievable validity.

Classifying adults' and children's faces by sex: computational investigations of subcategorical feature encoding

The faces of both adults and children can be classified accurately by sex, even in the absence of sex-stereotyped social cues such as hair and clothing (Wild et al., 2000). Although much is known from psychological and computational studies about the information that supports sex classification for adults' faces, children's faces have been much less studied. The purpose of the present study was to quantify and compare the information available in adults' versus children's faces for sex classification and to test alternative theories of how human observers distinguish male and female faces for these different age groups. We implemented four computational/neural network models of this task that differed in terms of the age categories from which the sex classification features were derived. Two of the four strategies replicated the advantage for classifying adults' faces found in previous work. To determine which of these strategies was a better model of human performance, we compared the performance of the two models with that of human subjects at the level of individual faces. The results suggest that humans judge the sex of adults' and children's faces using feature sets derived from the appropriate face age category, rather than applying features derived from another age category or from a combination of age categories.     

Equipercentile equating via data-imputation techniques

In the design of common-item equating, two groups of examinees are administered separate test forms, and each test form contains a common subset of items. We consider test equating under this situation as an incomplete data problem—that is, examinees have observed scores on one test form and missing scores on the other. Through the use of statistical data-imputation techniques, the missing scores can be replaced by reasonable estimates, and consequently the forms may be directly equated as if both forms were administered to both groups. In this paper we discuss different data-imputation techniques that are useful for equipercentile equating; we also use empirical data to evaluate the accuracy of these techniques as compared with chained equipercentile equating.A paper presented at the European Meeting of the Psychometric Society, Barcelona, Spain, July, 1993.
