Delay discounting of qualitatively different reinforcers in rats

Humans discount larger delayed rewards less steeply than smaller rewards, whereas no such magnitude effect has been observed in rats (and pigeons). It remains possible that rats' discounting is sensitive to differences in the quality of the delayed reinforcer even though it is not sensitive to amount. To evaluate this possibility, Experiment 1 examined discounting of qualitatively different food reinforcers: highly preferred versus nonpreferred food pellets. Similarly, Experiment 2 examined discounting of highly preferred versus nonpreferred liquid reinforcers. In both experiments, an adjusting-amount procedure was used to determine the amount of immediate reinforcer that was judged to be of equal subjective value to the delayed reinforcer. The amount and quality of the delayed reinforcer were varied across conditions. Discounting was well described by a hyperbolic function, but no systematic effects of the quantity or the quality of the delayed reinforcer were observed.     

Living in a Dissonant World: Toward an Agonistic Cosmopolitics for Education

As a flashpoint for specific instances of conflict, Muslim sartorial practices have at times been seen as being antagonistic to “western” ideas of gender equality, secularity, and communicative practices. In light of this, I seek to highlight the ways in which such moments of antagonism actually might be understood on “cosmopolitical” terms, that is, through a framework informed by a critical and political approach to cosmopolitanism itself. Thus, through an “agonistic cosmopolitics” I here argue for a more robust political understanding of what a cosmopolitan orientation to cultural difference can offer education. The paper moves from a focus on harmony to agonism and from cosmopolitanism to the cosmopolitical, and within each I discuss the questions of democracy and universality, respectively. Drawing on, the work of Chantal Mouffe, Judith Butler and Bonnie Honig, I discuss the basis upon which our agonistic interactions can inform education in promoting better ways of living together. This requires, in my view, nothing less than a clear understanding of the very difficulties of pluralism and a questioning of some of the ways we often reflect on the political dimension of these difficulties. I offer some reflections on what an agonistic cosmopolitics has to offer the debates surrounding the wearing of various forms of Muslim dress in schools in the conclusion. My overall claim is that cosmopolitanism as a set of ideas that seek more peaceful forms of living together on a global scale is in need of a theoretical framework that faces directly the difficulties of living in a dissonant world.     

Patterns of Community Violence Exposure During Adolescence

This study examined cross-sectional and longitudinal patterns of community violence exposure and malleable predictors of these exposure patterns among a community sample of 543 urban African American early adolescents (45.3% female; mean age: 11.76). In each of grades 6, 7, and 8, latent class analyses revealed two patterns of community violence exposure: high exposure and low exposure. For the majority of participants, experiences with community violence were similar at each grade. Impulsive behavior and depressive symptoms distinguished adolescents in the high and low exposure classes in grade 6. Implications for interventions to prevent community violence exposure are discussed.     

Antecedents and Consequences of Perceived Personal Gender Discrimination: A Study of Solicitors in Hong Kong

Informed by social identity theory, we developed a model to examine the antecedents and consequences of perceptions of personal gender discrimination. In the model, gender, gender identity, and perceived gender bias against women are considered as salient predictors of perceived personal gender discrimination, and organizational commitment and intentions to leave are considered as the outcome variables. Structural equation modeling (SEM) was used to analyze the data collected from a sample of practicing solicitors in Hong Kong. We found that (a) women perceived more personal gender discrimination and gender bias against women than did men, (b) gender moderated the relationship between perceived gender bias against women and perceived personal gender discrimination, (c) the positive effect of gender bias against women on gender discrimination was more strongly positive for women than for men, and (d) perceived personal gender discrimination affected organizational commitment and intentions to leave. Theoretical and practical implications are discussed.     

Why Expecting Conflict Is Good

To understand whether young women's expectations of marriage-career role conflict may lead to strategic plans for combining roles and more successful role combination, data were analyzed from 117 women, primarily Caucasian, completing surveys in the Women's Life Paths Study in 1967 as college seniors and again in 1981. Seniors who wanted careers but anticipated conflict more often combined marriage and full-time career in 1981 than did those who wanted careers but expected no conflict. The latter combined marriage and career even less often than did those not initially wanting careers. Those who expected conflict asserted their career intentions with spouses, postponed childbearing, and had fewer children by 1981. Women not combining roles in 1981 most often reported conflict. Women with supportive partners less often reported conflict.
