Attribute-value functions as global interpretations of attribute importance

In order to better understand decision maker’s perceptions of the importance of attributes, Goldstein (1990) differentiates between global and local interpretations of attribute importance. While the appreciation for the distinction is growing, research on the relationship between measures of global and local importance is inconclusive. We believe that these inconclusive findings are caused by operationalizing global attribute importance with single-point measures that implicitly assume that the global interpretation of attribute importance linearly depends on the relevant range of context-specific attribute levels. To address this, we propose to operationalize the global interpretation of attribute importance by estimating decision makers’ attribute-value functions. Two empirical studies demonstrate that the shape of attribute-value functions changes from concave to convex with global attribute importance. Furthermore, the steepness of these functions increases with global attribute importance while the diminishing sensitivity decreases. Finally, it is demonstrated that the inconclusive findings about the relationship between common, single-point measures of global and local attribute importance is driven by non-linearities in decision makers’ attribute-value functions. The results suggest great promise for future research on using decision makers’ attribute-value functions for measuring the importance of attributes.     

竹简《文子》天道论初探

＂天道＂是中国思想史上的重要概念。在竹简《文子》中,天道不仅是对于世界万物起源的认识,也是对社会发展规律性的认识,它具有自然和社会双重属性。竹简《文子》的天道论继承了老子＂道生于有＂的思想,但否认＂有生于无＂,＂有＂是其终极。人的行为必须遵循天道。竹简《文子》中对于＂天道＂自然属性和社会属性的阐释,也为后世很多思想家所继承。     

Power and consumer behavior: How power shapes who and what consumers value

The current paper reviews the concept of power and offers a new architecture for understanding how power guides and shapes consumer behavior. Specifically, we propose that having and lacking power respectively foster agentic and communal orientations that have a transformative impact on perception, cognition, and behavior. These orientations shape both who and what consumers value. New empirical evidence is presented that synthesizes these findings into a parsimonious account of how power alters consumer behavior as a function of both product attributes and recipients. Finally, we discuss future directions to motivate and guide the study of power by consumer psychologists.     

论责任心的类型与层级

责任心的类型多种多样,并且,自个体步入前习俗水千开始,其责任心就既不再是有与无的关系,也不是一个平面关系,而是一个呈金字塔形的层级关系。就正确责任心而言,将“他律型责任心”与“自律型责任心”、“硬角色责任心”与“软角色责任心”进行排列组合,并考虑到量的差异,就生出了发展水平高低不同的多层次责任心：其中,拥有他律型硬角色责任心,是做个有责任心之人的底线。拥有第二层次的责任心有两种典型做法：一是拥有一般水平的自律型硬角色责任心;二是拥有他律型软角色责任心。个体二旦拥有一般水平的自律型软角色责任心,其责任心就达到了第三层次。拥有第四层次的责任心有两种典型做法：拥有高水平的自律型硬角色责任心,或拥有舍小我成大我且自律型软角色责任心。拥有高水平自律型软角色责任心,是做一个有责任心之人的最高境界。     

How Social Dominance Orientation Affects Union Participation: The Role of Union Identification and Perceived Union Instrumentality

Bridging social dominance theory and labour studies, this field study investigated the mechanisms underpinning the relationship between rejection of group‐based domination and participation in union activities. Respondents (N = 135) were members of a public sector union in California, that is, a hierarchy‐attenuating institution. Results revealed that union identification mediated the negative relationship between social dominance orientation and active union participation. Moreover, the mediational effect of union identification was moderated by perceived union instrumentality (i.e. outcome‐ and process‐based benefits afforded by the union), indicating that the relationship between union identification and participation was stronger among those union members who consider that the union affects workplace justice. The findings reveal the importance of both identity‐based and instrumental motivations underlying union participation. The novelty of applying social dominance theory to union behaviour is underscored. Copyright © 2012 John Wiley & Sons, Ltd.     

A Comprehensive Literature Review of the Rank Reversal Phenomenon in the Analytic Hierarchy Process

During the last few decades, several multi‐criteria decision analysis methods have been proposed to help in selecting the best compromise alternatives. Among them, analytic hierarchy process (AHP) and its applications have attracted much attention from academics and practitioners. However, since the early 1980s, critics have raised questions regarding its proper use. One of them concerns the unacceptable changes in the ranks of the alternatives, called rank reversal, upon changing the structure of the decision. Several modifications were suggested to preserve ranks. In this paper, a classification scheme and a comprehensive literature review are presented in order to uncover, classify and interpret the current research on AHP methodologies and rank reversals. On the basis of the scheme, 61 scholarly papers from 18 journals are categorized into specific areas. The specific areas include the papers on the topics of adding/deleting alternatives and the papers published in adding/deleting criteria. The scholarly papers are also classified by (1) year of publication, (2) journal of publication, (3) authors' geographic location and (4) using the AHP in association with other methods. It is hoped that the paper can meet the needs of researchers and practitioners for convenient references of AHP methodologies and rank reversals and hence promote the future of rank reversal research.

TMS to the “occipital face area” affects recognition but not categorization of faces

The human cortical system for face perception is comprised of a network of connected regions including the middle fusiform gyrus (“fusiform face area” or FFA), the inferior occipital cortex (“occipital face area” or OFA), and the superior temporal sulcus. The traditional hierarchical feedforward model of visual processing suggests information flows from early visual cortex to the OFA for initial face feature analysis to higher order regions including the FFA for identity recognition. However, patient data suggest an alternative model. Patients with acquired prosopagnosia, an inability to visually recognize faces, have been documented with lesions to the OFA but who nevertheless show face-selective activation in the FFA. Moreover, their ability to categorize faces remains intact. This suggests that the FFA is not solely responsible for face recognition and the network is not strictly hierarchical, but may be organized in a reverse hierarchical fashion. We used transcranial magnetic stimulation (TMS) to temporarily disrupt processing in the OFA in neurologically-intact individuals and found participants’ ability to categorize intact versus scrambled faces was unaffected, however face identity discrimination was significantly impaired. This suggests that face categorization but not recognition can occur without the “earlier” OFA being online and indicates that “lower level” face category processing may be assumed by other intact face network regions such as the FFA. These results are consistent with the patient data and support a non-hierarchical, global-to-local model with re-entrant connections between the OFA and other face processing areas.     

Mirror,mirror on the wall,who’s the fairest of them all? Thinking that one is attractive increases the tendency to support inequality

Five studies tested the hypothesis that self-perceived attractiveness shapes people’s perceptions of their social class (subjective SES), which, in turn, shape how people respond to inequality and social hierarchies. Study 1 found that self-perceived attractiveness was associated with support for group-based dominance and belief in legitimizing ideologies, and that these relationships were mediated by subjective social class. Subsequent experiments showed that higher self-perceived attractiveness increased subjective SES, which in turn, increased SDO (Study 2 and Study 5); promoted stronger beliefs in dispositional causes of inequality (Study 3); and reduced donations to a movement advocating for social equality (Study 4). By contrast, lower self-perceived attractiveness decreased subjective SES, which in turn, led to a greater tendency to reject social hierarchies and to construe inequality in terms of contextual causes. These effects emerged even after controlling for power, status, and self-esteem, and were not simply driven by inducing people to see themselves positively on desirable traits (Study 4 and Study 5).     

A Sense of Powerlessness Fosters System Justification: Implications for the Legitimation of Authority,Hierarchy, and Government

In an attempt to explain the stability of hierarchy, we focus on the perspective of the powerless and how a subjective sense of dependence leads them to imbue the system and its authorities with legitimacy. In Study 1, we found in a nationally representative sample of U.S. employees that financial dependence on one's job was positively associated with the perceived legitimacy of one's supervisor. In Study 2, we observed that a general sense of powerlessness was positively correlated with the perceived legitimacy of the economic system. In Studies 3 and 4, priming experimental participants with feelings of powerlessness increased their justification of the social system, even when they were presented with system‐challenging explanations for race, class, and gender disparities. In Study 5, we demonstrated that the experience of powerlessness increased legitimation of governmental authorities (relative to baseline conditions). The processes we identify are likely to perpetuate inequality insofar as the powerless justify rather than strive to change the hierarchical structures that disadvantage them.
