中国人眼光谱相对视亮度函数的研究

问 题 人眼对光谱各波长的灵敏度,是产生一种阈限反应或主观相等亮度所需要的辐射能量的倒数。它们原称光谱视亮度,现在我们称之为光谱相对视亮度。即使是等能光谱,各波长引起的相对视亮度也很不相同。具体测量时除绝对阈限法外,一般常用匹配法:使人眼将不同波长的光谱色光分别和一个固定强度的白色标准光作亮度匹配,达     

Leader–follower risk orientation incongruence,intellectual stimulation,and creativity: A configurational approach

Prior work suggests that follower and leader risk orientation is positively associated with follower creativity. We suggest that this view is oversimplified and propose that follower creativity can be stimulated when leader and follower have diverging risk orientations. We, therefore, apply a configurational approach to creativity, evaluating varying combinations of leader and follower risk orientation on follower creativity. Across two field studies, we demonstrate that (a) follower creativity increases as leaders’ and followers’ risk orientations become more discrepant (i.e., incongruent); (b) follower creativity is higher when leader–follower dyads are congruent at moderate levels of risk orientation compared to congruence at the extremes (i.e., low and high levels); (c) follower‐experienced intellectual stimulation mediates the relationship between leader–follower risk orientation incongruence and congruence and follower creativity; and (d) that leader authority openness moderates the indirect effect of leader–follower risk orientation incongruence on creativity via follower‐experienced intellectual stimulation. Theoretical and practical implications specific to creativity and leader–follower relationships are discussed.     

Bootstrap-Calibrated Interval Estimates for Latent Variable Scores in Item Response Theory

In most item response theory applications, model parameters need to be first calibrated from sample data. Latent variable (LV) scores calculated using estimated parameters are thus subject to sampling error inherited from the calibration stage. In this article, we propose a resampling-based method, namely bootstrap calibration (BC), to reduce the impact of the carryover sampling error on the interval estimates of LV scores. BC modifies the quantile of the plug-in posterior, i.e., the posterior distribution of the LV evaluated at the estimated model parameters, to better match the corresponding quantile of the true posterior, i.e., the posterior distribution evaluated at the true model parameters, over repeated sampling of calibration data. Furthermore, to achieve better coverage of the fixed true LV score, we explore the use of BC in conjunction with Jeffreys’ prior. We investigate the finite-sample performance of BC via Monte Carlo simulations and apply it to two empirical data examples.     

Cultural differences in estimation of other people's self-construals: Comparison of Korea and USA

The current study examined cultural differences in the relationship between individuals' self-ratings and their estimation of others on independent and interdependent self-construals. With data from undergraduates in the USA and Korea, findings showed that, in both USA and Korea, participants rated themselves higher than others on independent self-construal. For interdependent self-construal, however, Korean participants rated themselves higher than others, whereas American participants rated themselves lower than others. The positive relationship between self-esteem and the extent to which self-ratings exceeded ratings of others on independent self-construal was stronger for Korean than for American participants.

The authors describe how reflection on and discussion of myths and fairy tales in supervision may help transcend cultural boundaries and increase multicultural understanding. Las historias se han utilizado durante mucho tiempo en diversas culturas y escenarios para facilitar la comprensión de significado y aumentar el nivel de conciencia. Los autores describen cómo la reflexión y la discusión de mitos y cuentos en la supervisión pueden ayudar a trascender barreras culturales y elevar el entendimiento multicultural.     

Cultural Variations in Reasons for Advice Seeking

Five studies examined cultural differences in reasons for advice‐seeking behaviors. Content analyses in Study 1A and self‐ratings in Study 1B consistently revealed that Euro‐Canadians were more likely than East Asians (mainly Chinese) to seek advice for informational reasons, whereas East Asians were more likely than Euro‐Canadians to seek advice for relational reasons. Study 2A showed that Chinese displayed a higher level of relationship concern than Euro‐Canadians in deciding from whom to seek advice in a decision dilemma. Study 2B found that, although Chinese and Euro‐Canadians did not differ from each other on willingness to pay for informational advice, Chinese were willing to pay more for building a relationship with the advisor through advice seeking than Euro‐Canadians were. Study 3 explored how the advice giver might perceive an advice seeker in terms of their competence and the closeness of their relationship after advice was sought for various reasons. We found that relationally oriented advice seeking increased the perceived competence of the advice seeker among Chinese more than among Euro‐Canadians. Information‐oriented advice seeking increased the perceived closeness between the advice seeker and advice giver among Chinese more than among Euro‐Canadians. Implications for other aspects of advice exchange are discussed. Copyright © 2016 John Wiley & Sons, Ltd.

Fuzzy MCDM based on the concept of α‐cut

In a fuzzy multiple criteria decision‐making (MCDM) problem, with a hierarchical structure of more than two levels and involving multiple decision‐makers (DMs), to find the exact membership functions of the final aggregation ratings of all feasible alternatives is almost impossible. Thus, ranking methods based on exact membership functions cannot be utilized to rank the feasible alternatives and complete the optimal selection. To resolve the above‐mentioned complexity and to incorporate assessments of all DMs' viewpoints, in this paper a fuzzy MCDM method with multiple DMs, based on the concepts of fuzzy set theory and α‐cut, is developed. This method incorporates a number of perspectives on how to approach the fuzzy MCDM problem with multiple DMs, as follows: (1) combining quantitative and qualitative criteria as well as negative and positive ones; (2) using the generalized means to develop the aggregation method of multiple DMs' opinions; (3) incorporating the risk attitude index β to convey the total risk attitude of all DMs by using the estimation data obtained at the data input stage; (4) employing the algebraic operations of fuzzy numbers based on the concept of α‐cut to calculate the final aggregation ratings and develop a matching ranking method for proposed fuzzy MCDM method with multiple DMs. Furthermore, we use this method to survey the site selection for free port zone (FPZ) in Taiwan as an empirical study to demonstrate the proposed fuzzy MCDM algorithm. The result of this empirical investigation shows that the port of Kaohsiung, the largest international port of Taiwan as well as the sixth container port in the world in 2004, is optimal for the Taiwan government in enacting the plan of FPZ.

Preschoolers’ Emotional Understanding and Psychosocial Adjustment in Korea: The Moderating Effect of Maternal Attitude towards Emotional Expressiveness

The purpose of the present study was to examine the role of maternal attitude towards children’s emotional expressiveness in Korean preschoolers’ emotional understanding and psychosocial adjustment. Preschoolers (N?=?70) participated in an emotional understanding task comprised of identifying cartoon character’s emotional reaction to particular emotion-eliciting situations. Maternal attitude towards children’s emotional expressiveness, as well as teachers’ rating of children’s behavior problems and social competence were measured. Children’s emotional understanding was negatively correlated with teacher-reported behavior problems and positively associated with social competence. In line with recent research on the socialization of emotional expressiveness, controlling maternal attitude towards children’s positive emotional expressiveness was negatively correlated with teacher-reported behavior problems. Conversely, mothers’ accepting attitude towards children’s negative emotional expressiveness was also negatively correlated with behavior problems. Finally, maternal attitude toward children’s positive emotional expressiveness moderated the relationship between emotional understanding ability and behavior problems and social competence. Such findings suggest that maternal attitude, particularly attitude regarding specific type of emotional expressiveness, is one of the key factors that may predict preschooler’s psychosocial outcomes.     

Narcissistic personality and risk perception among Chinese aviators: The mediating role of promotion focus

Optimism bias is a crucial feature of risk perception that leads to increased risk‐taking behaviour, which is a particularly salient issue among pilots in aviation settings due to the high‐stakes nature of flight. The current study sought to address the roles of narcissism and promotion focus on optimism bias in risk perception in aviation context. Participants were 239 male flight cadets from the Civil Aviation Flight University of China who completed the Narcissistic Personality Inventory‐13, the Work Regulatory Focus Scale, and an indirect measure of unrealistic optimism in risk perception, which measured risk perception for the individual and the risk assumed by other individuals performing the same task. Higher narcissism increased the likelihood of underestimating personal risks, an effect that was mediated by high promotion focus motivation, such that high narcissism led to high promotion focus motivation. The findings have important implications for improving the accuracy of risk perception in aviation risks among aviators.
