Objective. This study examines how preferences for different types of applicants exercised by admission offices at elite universities influence the number and composition of admitted students. Methods. Logistic regression analysis is used to link information on the admission decision for 124,374 applications to applicants' SAT scores, race, athletic ability, and legacy status, among other variables. Results. Elite universities give added weight in admission decisions to applicants who have SAT scores above 1500, are African American, or are recruited athletes. A smaller, but still important, preference is shown to Hispanic students and to children of alumni. The athlete admission “advantage” has been growing, while the underrepresented minority advantage has declined. Conclusions. Elite colleges and universities extend preferences to many types of students, yet affirmative action—the only preference given to underrepresented minority applicants—is the one surrounded by the most controversy. 相似文献

The methodology and results reported in this paper are based on an analysis of a hypothetical accident occurring in a two unit power plant with shared systems (i.e., the diesel generator, the emergency service water, and the residual heat removal service water systems). The accident postulated is a loss of coolant accident (LOCA) in one out of two nuclear units in conjunction with a loss of offsite power (LOOP) and a failure of one out of four diesel generators to start. To analyze the intersystem effects, we needed to develop and apply a new methodology, intersystem common cause analysis (ICCA). The ICCA methodology revealed problems which were not identified by the traditional intrasystem failure modes and effects analysis (FMEA) performed earlier by the design teams. The first potential problem arises if one unit experiences a LOCA and diesel generator failure while one loop of its residual heat removal system is in the suppression pool cooling mode (SPCM); in this event, it is likely that minimum emergency core cooling system (ECCS) requirements will not be met. The second potential problem arises if a diesel generator fails while both units are simultaneously subjected to a controlled forced shutdown (a LOCA need not be postulated for either unit); in this event, it is likely that one unit will be required to use a heat removal path identified as off-normal in the final safety analysis report (FSAR) for the two unit plant. These and other potential concerns identified through application of the ICCA presented here were resolved early in the design phase. 相似文献

In an extension of previous research on individual differences in deception ability, 35 undergraduate subjects were administered standardized measures of social skills and public self-consciousness and their attitudes on a variety of sociopolitical attitudes were measured. Later, subjects were videotaped while giving pro-attitudinal (truthful) and counter-attitudinal (deceptive) presentations to a videocamera. Videotaped presentations were content analyzed for various verbal and nonverbal cues, and were shown to untrained judges who rated each on a scale of truthfulness/believability. Results of structural modeling analyses indicated that socially skilled subjects were judged as believable regardless of whether they were truth-telling or deceiving. Individuals high in public self-consciousness were less successful deceivers. Most importantly, these relationships were mediated by certain behavioral cues, particularly cues of verbal fluency, which were consistently associated with judgments of truthfulness. These results have both theoretical and methodological implications for future deception research.This research was supported by intramural grants from California State University, Fullerton (CSUF) Foundation to the first author.

Let X, T, Y be random vectors such that the distribution of Y conditional on covariates partitioned into the vectors X = x and T = t is given by f(y; x, ), where = (, (t)). Here is a parameter vector and (t) is a smooth, real–valued function of t. The joint distribution of X and T is assumed to be independent of and . This semiparametric model is called conditionally parametric because the conditional distribution f(y; x, ) of Y given X = x, T = t is parameterized by a finite dimensional parameter = (, (t)). Severini and Wong (1992. Annals of Statistics 20: 1768–1802) show how to estimate and (·) using generalized profile likelihoods, and they also provide a review of the literature on generalized profile likelihoods. Under specified regularity conditions, they derive an asymptotically efficient estimator of and a uniformly consistent estimator of (·). The purpose of this paper is to provide a short tutorial for this method of estimation under a likelihood–based model, reviewing results from Stein (1956. Proceedings of the Third Berkeley Symposium on Mathematical Statistics and Probability, vol. 1, University of California Press, Berkeley, pp. 187–196), Severini (1987.

This paper describes some of the characteristics of relationship patterns established by partners with one depressed member. Depressive dyadic and triadic relationships are characterized by repetitive and patterned verbal and non-verbal behavior which is designated as “microcycling”. A distinction is made between the psychotic and neurotic types. The personality characteristics of the “caretakers” are described. The psychodynamics of depressive dyadic relationships involves reaction formation against hidden mutual hostilities and a struggle for power. The triadic relationship secures a third party involvement to maintain a balance in the dyadic pair. Depressive dyadic and triadic relationships inhibit personal growth and fixate the individual at an early stage of psychosexual development. Treatment approaches include therapy of the partners' relationship and of the individual's pathological dynamics. 相似文献

Physical distress, emotional distress, and cognitive fatigue are common symptons of burnout. The consequences of burnout affect the effectiveness of the care giver, the client, and the agency employing the burned out worker. The authors emphasize the societal context in which we all work and the changes in this context that have led to changes in the attitudes, behaviors, and roles of care givers and recipients. The change of role perception and the role behavior has occurred in a wide variety of public agencies. The authors suggest establishing agency guidelines for personal and system limitations concerning assistance to clients. Care givers can also work on an individual basis with clients and outline limits of assistance. As more people seek assistance when resources are limited, the need to build realistic expectations for the care giver, client, and agencies increase. 相似文献

A short-term postabortion group for adolescents was developed. Three groups were conducted in an adolescent mental health clinic within an urban high school-based health clinic. The clinical group experiences offered the adolescents an opportunity to integrate the experience of pregnancy and the abortion decision into their lives. At follow up, adolescents who participated in th postabortion counseling group indicated that they chose and used a method of birth control, did not repeat an unplanned pregnancy, and remained in high school. 相似文献

Social workers who provide end-of-life care do not always see themselves as clinicians. This paper identifies what is clinical
in work with the dying. Social workers routinely elicit sources of cultural and psychological ways of coping, tolerate difficult
and painful affects, and balance hope with compassion. They work in multidisciplinary teams and on every level (individual,
family, and systemically) to avoid splitting or blame. Further, dying is a relational event. Social workers who work with
the dying often stand in the most intimate spaces and therefore use themselves intersubjectively. This work requires considerable
courage and self-care.

The British Menopause Society Council is committed to provide up-to-date authoritative reviews to aid health professionals to inform and advise women about key issues in postreproductive health. This guidance refers to non-estrogen-based treatments for menopausal symptoms, such as hot flushes, symptoms of urogenital atrophy and lack of sexual desire. Treatment of choice should be based on up to-date information and targeted to individual women's needs. Non-hormonal strategies may be useful for women with estrogen-dependent disease such as breast cancer. 相似文献
