One-hundred and seventeen college-aged women at varying risk for developing bulimia answered a number of questions addressing their attitudes toward and comfort with sexuality as well as their sexual and contraceptive history. Risk for developing bulimia was unrelated to sexual attitudes and weakly related to greater comfort with sexuality. High-risk women reported first engaging in intercourse at earlier ages and were also more likely to engage in risky contraceptive behavior than their lower risk counterparts. Despite their tendency to report a greater number of previous sexual partners, high-risk women currently engaged and expected to continue to engage in sex less frequently than lower risk women. Taken together with previous findings, results suggest that the relationship between risk for bulimia and certain patterns of sexual behavior reflects a general cycle of impulsive and controlling behavior exhibited by high-risk women. Limitations and implications of the present study are discussed.Half-time Editorial Assistant, Journal of Social and Clinical Psychology. Quarter-time research assistant, University of Kansas.

The prospects for European Union citizenship are sometimes discountedby reference to homogeneity in the United States compared todiversity in the European Union. This article suggests thatthere may be more similarities between the two systems thanis sometimes supposed by many observers. Even though there areimportant differences, both systems have had to address similarquestions about how to combine the benefits of integration andthe protection of rights. In discussing the common and divergentfeatures, the author argues that comparison also reveals thepossibility that it is diversity, not homogeneity, that is necessaryto the protection of citizenship's rights.  相似文献

"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among these are life, liberty and the pursuit of happiness. That, to secure these rights, governments are instituted among men, deriving their just powers from the consent of the governed." These words from the Preamble to the Declaration of Independence, proclaimed a conviction and announced a challenge for our newly formed nation. Today, they either stir the American heart with pride or generate nostalgia for a time when any truth was self-evident and the right to life was deemed inalienable.  相似文献

Suppose the optimizing consumer only has local information, then what? Obviously, there will be a random element of consumption. The link between the frequency distribution of consumption by person and preference surface is worked out. Under convex preferences there will be a unimodal distribution and conversely. A local optimizing theory of addictive behavior is developed from nonconvex preferences. The resulting bimodal distribution of consumption implies a nonrobust outcome for median voter politics. Such a local optimizing model of addiction is compared with globally optimizing models of addiction.  相似文献

Young adult adoptees and nonadoptees provided retrospective accounts of family relationships from infancy to young adulthood. Adoptive families were portrayed as more cohesive and adaptable than nonadoptive families. Adoptive fathers were recalled as being closer to their children then were nonadoptive fathers in the years preceding adolescence. Within the same time frame, adoptive mothers were drawn in a less hierarchical relation to their children than were other parents. Also, while adoptive males saw themselves as presently unconnected to their adoptive parents, adopted females perceived themselves as more connected to their parents in the present than any other period of time. Openness of communication and acknowledgment of difference in adoptive family formation varied with graphic retrospective accounts. Results were considered in terms of discontinuities between reported observations of adoptive families and adoptees' personal reflections on family developmental history.Received PhD in clinical psychology from the State University of New York at Stony Book. Research interests: adoptive family relations, social attributions of children and their parents.Received M.A. from the University of Guelph, Guelph, Ontario, Canada N1G 2W1.
