Taxicab Correspondence Analysis

Taxicab correspondence analysis is based on the taxicab singular value decomposition of a contingency table, and it shares some similar properties with correspondence analysis. It is more robust than the ordinary correspondence analysis, because it gives uniform weights to all the points. The visual map constructed by taxicab correspondence analysis has a larger sweep and clearer perspective than the map obtained by correspondence analysis. Two examples are provided. This research was financed by the Natural Sciences and Engineering Research Council of Canada. The author thanks Serge Vienneau for his help regarding the graphical displays, and also thanks the editor, associate editor, and two reviewers for their constructive comments.

Modern racism and neo‐liberal globalization: the discourses of plausible deniability and their multiple functions

Recently, considerable energy has been focused on extending the mandate of anti‐racism. Modern (or symbolic) racism and discursive psychology have argued that racism has taken on more covert forms. A longitudinal examination of newspaper coverage of two important race‐related newsprint stories in New Zealand (involving Winston Peters, Tuku Morgan and New Zealand First) identified discourses of ‘plausible deniability’ involved in warranting or defending statements about minorities against accusations of racism. We discuss implications of symbolic politics for minorities who are perceived to have violated societal norms, and show how nationalism is used as a framework for denying racist intent. Analyses of historical context show how ‘race’ forms only one lens from which to view issues of intergroup relations. While the press was sensitive to issues of racism, they demonstrated little awareness of concurrent issues of neo‐liberal economics, or market fundamentalism. Anti‐racism may be motivated not only by the ideals of egalitarianism, but also by underlying dynamics of economic power in a global economy. Copyright © 2006 John Wiley & Sons, Ltd.     

Collective estimation: Accuracy,expertise, and extroversion as sources of intra-group influence

Although estimations typically possess correct answers, these answers may be difficult to demonstrate to others. However, providing external information may increase their demonstrability. In this experiment, individuals (N = 60) and 6-person groups (N = 360) generated estimations with or without frames of reference. We hypothesized that estimations involving frames of reference would be best fit by models predicting intra-group influence based on the accuracy of alternatives or of members in general. Conversely, we hypothesized that estimations not involving frames of reference would be best fit by models predicting influence based on member extroversion or proposal centrality. Results indicate that groups outperformed individuals and that estimations generated in the presence of frames of reference were superior to those generated in their absence. Accuracy and expertise schemes provided the best fit when frames of reference were provided, whereas an extroversion scheme provided the best fit when they were not.     

Recurrent binge eating with and without the "undue influence of weight or shape on self-evaluation": implications for the diagnosis of binge eating disorder

Levels of eating disorder psychopathology, impairment in psycho-social functioning and use of health services were compared among probable cases of binge eating disorder (BED) with and without extreme weight or shape concerns ("undue influence of weight or shape on self-evaluation") recruited from a large community sample of women. Data for obese non-binge eaters (n=457), also recruited from the community sample, and for a clinical sample of eating disorder patients (n=128), recruited separately, were included for comparative purposes. BED cases who reported extreme weight or shape concerns (n=51, 46.4%) had significantly higher levels of eating disorder psychopathology and functional impairment than those who did not report such concerns (n=59), after controlling for between-group differences in age and body weight. In addition, BED cases who reported extreme weight or shape concerns were more likely to have sought treatment for an eating or weight problem than those who did not. Whereas levels of eating disorder psychopathology and functional impairment were markedly elevated among BED cases with extreme weight or shape concerns, BED cases who did not report extreme weight or shape concerns resembled obese non-binge eaters in most respects. The findings support the inclusion of an undue influence of weight or shape on self-evaluation as a diagnostic criterion for BED. In the absence of this influence, eating disorders that otherwise resemble BED do not appear to be "clinically significant".     

探寻巫乐舞对道教音乐的影响

中国道教音乐在千百年的历史演变中,由于其宗教自身发展的需要,吸纳了多种音乐素材,最终形成了形式完备、内涵丰富、中华文化底蕴深厚的传统音乐。本文经过大量音乐史料的深入分析研究,在古代历史史料的考证后认为,虽然至今现存的道教音乐内容丰富,构成成分纷繁复杂,但通过梳理甄别发现古代巫乐舞即是道教音乐的起源,也极大的影响着道教音乐的发展。     

Does Watching Smoking in Movies Promote Teenage Smoking?

ABSTRACT— Compared to adolescents with low exposure to smoking in movies, those with high exposure are about three times as likely to try smoking or become smokers. We have observed this effect in nationally representative samples using cross-sectional and longitudinal designs. This effect remains statistically significant after controlling for numerous other traditional risk factors, such as personality, parenting style, and sociodemographics. Indeed, the movie-smoking exposure effect on adolescent smoking initiation is greatest among those traditionally considered at lower risk for smoking, such as those low in sensation seeking and those whose parents do not smoke. In this article, we consider possible moderators and mediators of this important media effect as well as health-policy implications. The take-home message is that eliminating smoking in movies may prevent a substantial number of adolescents from smoking.     

Dual effects of implicit bystanders: Inhibiting vs. facilitating helping behavior

Encouraging consumers to engage in helpful behavior is a perennial task of marketers in non-profit and for-profit organizations. Recent research suggests that merely imagining the presence of others can lead to less helping behavior on a subsequent unrelated task (Garcia, S.M., Weaver, K.D., Moskowitz, G.B., and Darley, J.M. (2002). Crowded minds: The implicit bystander effect. Journal of Personality and Social Psychology, 83, 843–853.). The present analysis uncovers the boundary conditions of this effect. Across four studies, we establish that the degree to which a group situation fosters public scrutiny is an important moderator. When group primes are paired with public scrutiny, their inhibitive effect on helping behavior diminishes, and helping behavior on a subsequent task tends to increase. The present research thus adds complexity to previous findings by suggesting that implicit bystanders can both decrease and increase helping behavior.     

Social Influence on Political Judgments: The Case of Presidential Debates

Four experiments investigated the extent to which judgments of candidate performance in presidential debates could be influenced by the mere knowledge of others' reactions. In Experiments 1 and 2 participants watched an intact version of a debate or an edited version in which either "soundbite" one-liners or the audience reaction to those soundbites were removed. In Experiment 3 participants saw what was supposedly the reaction of their fellow participants on screen during the debate. Participants in Experiment 4 were exposed to the reactions of live confederates as they watched the last debate of an active presidential campaign. In all studies, audience reactions produced large shifts in participants' judgments of performance. The results illustrate the power of social context to strongly influence individuals' judgments of even large amounts of relevant, important information, and they support the categorization of presidential debates as ambiguous stimuli, fertile ground for informational social influence.
