Social change in the aftermath of successful minority influence

This chapter describes a programme of research on group dynamics in the aftermath of successful minority influence that reverses minority and majority positions within a group. Supporting the authors' gain - loss asymmetry model of change, converging evidence suggests that loss of the majority position generates strong disidentification from the superordinate group whereas gaining the majority position does not yield comparable identification. This overall decrease in identification is associated with a general increase in hostility, reduced helpfulness, and a desire to exit the group. Thus groups may be especially fragile following internal changes in the majority - minority positions. Additional research suggests that such a pattern of reactions to majority - minority change is a specifically group phenomenon (versus aggregates of individuals) and occurs when majority - minority reversals follow the attitude change of existing group members (versus an influx of new members). New majorities will increase their identification with the group when converts provide genuine support or when their new majority position persists over time. Implications of these findings for intra-group relations in the aftermath of social change are discussed.     

Fungible Weights in Multiple Regression

Every set of alternate weights (i.e., nonleast squares weights) in a multiple regression analysis with three or more predictors is associated with an infinite class of weights. All members of a given class can be deemed fungiblebecause they yield identical SSE (sum of squared errors) and R ² values. Equations for generating fungible weights are reviewed and an example is given that illustrates how fungible weights can be profitably used to evaluate parameter sensitivity in multiple regression. The author wishes to thank Drs. Robyn Dawes, William Grove, Markus Keel, Leslie Yonce, Joe Rausch, the editor, and three anonymous reviewers for helpful comments on earlier versions of this article.     

When and how politicians' disrespect affects voters' trust in the political system: The roles of social judgments and category prototypicality

We propose that one politician's disrespectful behavior can spill over to voters' generalized judgments of politicians and thereby affect trust in the political system. We delineate the spillover effect along the basic dimensions of social judgment, communion, and agency. Moreover, we argue that any spillover effect is contingent on the focal politicians' category prototypicality, that is, their representativeness of politicians as such. Conducting an experiment (N = 392) and a field study (N = 273), we found that politicians' respect only affected trust through generalized communion ratings. This spillover only occurred if the observed politician was perceived as prototypical. Our findings provide new insights on when and how individual politicians may be able to undermine voters' trust in the political system.     

Grace in Nature and History: Luther's Doctrine of Creation Revisited1

Abstract: Interpreting Luther's Trinitarian theology of creation, it is shown how Luther's doctrine of creation is modelled on his soteriology. In his writing Against Latomus(1521) Luther established his famous distinction between the external grace of God (favor dei) and the divine gift (donom): the living Christ. A similar distinction can be re‐constructed from Luther's theology of creation as presented in his catechisms, sermons, tracts, and exegetical writings. Just as Luther makes a distinction between the Christ who takes side for us within God, and the Christ who is dwelling in the heart of the believer, Luther makes a the distinction between the fatherly love toward humankind (benevolentia), and the Father, Son and Spirit, who are at work from within the life of the creatures in God's blessing (benedictio). There is an implicit notion of a pater pro nobis and a pater in nobis, which reflects, in the order of creation, the classic distinction between Christus pro nobis and Christus in nobis. According to Luther's theology of the Eucharist and divine blessing, there exists a union between God and creature, which has a similar structure as the union between Christ and believer. There are distinctions to be drawn as well as correlations to be seen between the order of creation and the order of salvation.     

Early stopping of clinical trials: charting the ethical terrain

The decision to terminate a clinical trial earlier than planned is often described as ethically problematic, but it is rarely systematically analyzed as an ethical issue in its own right. This paper provides an overview of the main ethical considerations at stake in such decisions and of the main tensions between these considerations. Arguments about informed consent and the impact of early stopping on research and society are explored. We devote particular attention to a familiar conflict that arises with special urgency when early data suggest that the experimental treatment is superior. Should the trial be stopped so that participants in the control group will not be allocated a seemingly inferior treatment, or should it continue in pursuit of evidence conclusive enough to improve the care of future patients? We scrutinize three ways to address this problem. Rather than dissolving the tension, they represent different trade-offs between the respective welfare interests of subjects and future patients.
