To date, hardly anything is known about the partner preferences of the intellectually gifted. The present study therefore examined the extent to which 354 gifted individuals judged 17 characteristics to be important in a (potential) partner and compared these ratings with those obtained from a community sample (n = 554). Among other things, it was expected that, among the gifted, a (potential) partner's high intelligence would be judged to be more important than among participants from the general community. It was also expected that single gifted individuals would judge a potential partner's high intelligence to be more important than gifted individuals involved in intimate relationships. Most of our predictions were supported, and results are discussed.  相似文献

The expanding legalization of same-sex marriage in the Western World may pose significant challenges for the relationship between many religious and socially conservative marriage and family therapists and their professional associations. In the present analysis, I look to the field of moral psychology, particularly Haidt's Moral Foundations Theory, to provide greater clarity regarding the nature of this tension and a resultant tightening of the boundaries of acceptable diversity that could ensue. I then outline some concerning indicators from mental health associations relative to their potential willingness to tolerate conservative perspectives in meaningful ways and identify some specific areas of possible tension for conservative therapists trying to integrate their deeply held moral values into ethical practice with same-sex couples, with a specific reference to the viability of “conscience clauses” and values-based referrals. I conclude with some recommendations through which the field of marriage and family therapy can reduce the potential for conflicts and thereby reassure these clinicians that they continue to be welcomed even if their vision of marriage differs from that which is formally endorsed by their professional associations.  相似文献

It is argued that the actual incidence of child maltreatment remains elusive and is, in fact, indeterminate. Factors that might be reflected in variations in child maltreatment rates, other than child harm or endangerment at least partially attributable to caretakers, are explored. But since most children residing in foster care in the United States have been placed there for the alleged reasons of child abuse and neglect, we might expect trends over time in the rate of alleged maltreatment to have some bearing on the out-of-home placement population rate. On the contrary, it is shown that the child placement population rate has risen in recent years, even though the overall child maltreatment rate has not. Based on existing data, the child placement population in the United States is calculated to have been nearly one million children on any given day in 2011, higher than at any point throughout the previous century. Brief comparisons are made with child maltreatment and child placement trends in other countries.  相似文献

We investigate the welfare properties of the one‐sector neoclassical growth model with uninsurable idiosyncratic shocks. We focus on the notion of constrained efficiency used in the general equilibrium literature. Our characterization of constrained efficiency uses the first‐order condition of a constrained planner's problem. This condition highlights the margins of relevance for whether capital is too high or too low: the factor composition of income of the (consumption‐)poor. Using three calibrations commonly considered in the literature, we illustrate that there can be either over‐ or underaccumulation of capital in steady state and that the constrained optimum may or may not be consistent with a nondegenerate long‐run distribution of wealth. For the calibration that roughly matches the income and wealth distribution, the constrained inefficiency of the market outcome is rather striking: it has much too low a steady‐state capital stock.  相似文献

Before choosing among two actions with state‐dependent payoffs, a Bayesian decision‐maker with a finite memory sees a sequence of informative signals, ending each period with fixed chance. He summarizes information observed with a finite‐state automaton. I characterize the optimal protocol as an equilibrium of a dynamic game of imperfect recall; a new player runs each memory state each period. Players act as if maximizing expected payoffs in a common finite action decision problem. I characterize equilibrium play with many multinomial signals. The optimal protocol rationalizes many behavioral phenomena, like “stickiness,” salience, confirmation bias, and belief polarization.  相似文献

The projection of mortality rates requires inter alia close examination of the mortality experience of a population over a long period of time and will usually also involve the analysis of mortality trends by cause of death. In two of the more important recent contributions, techniques were devised for explaining change in life expectancy in terms of mortality changes in particular age groups and by different causes of death. The approaches adopted by the authors differ, and the purpose of this article is to reconcile the two and tie the results in with those obtained by earlier writers. A new method for explaining the change in a life expectancy differential in terms of the observed changes in the mortality differentials and the observed change in overall mortality level is also described.  相似文献
