This study of female and male undergraduate business majors explored the relationship of their preferred future career-marriage arrangement to their relationship and work values, work motivation, and gender role orientation Results indicate that the dual-career, career-job, and career-home groups showed significant differences on these dimensions. Additionally, sex and gender role differences reflected cultural stereotypes of achievement orientation in men and barriers to career pursuits of women. The results are discussed in terms of interpersonal, intrapersonal, and societal factors underlying career-marriage aspirations. Implications for practitioners and suggestions for future research are given. 相似文献

Sociometric measures were used to predict help seeking behaviors of youth in a residential treatment center. Seventeen female adolescents with conduct disorders were asked to choose three peers in their group who were most popular, similar, and competent. These sociometric measures were correlated with the degree to which the participants would seek help from their peers across four problem scenarios representing actual situations encountered in residential settings. A multiple linear regression analysis suggested that sociometric measures of “competence” was the best predictor of intentions to seek help across the problem scenarios. Discussion focused on the implications of using sociometric measures within a residential treatment setting. 相似文献

This paper presents a nonmonotonic deontic logic based on commonsense entailment. It establishes criteria a successful account of obligation should satisfy, and develops a theory that satisfies them. The theory includes two conditional notions of prima facie obligation. One is constitutive; the other is epistemic, and follows nonmonotonically from the constitutive notion. The paper defines unconditional notions of prima facie obligation in terms of the conditional notions. 相似文献

Levels and correlates of parental support, peer support, partner support, and/or spiritual support among African American
and Caucasian youth were examined in three contexts: adolescent pregnancy (Study 1), first year of college (Study 2), and
adolescence and young adulthood (ages 15–29; Study 3). Partially consistent with a cultural specificity perspective, in different
contexts different support sources were higher in level and/or more strongly related to adjustment for one ethnic group than
the other. Among pregnant adolescents, levels of spiritual support were higher for African Americans than Caucasians; additionally,
peer support was positively related to well-being only for African Americans whereas partner support was positively related
to well-being only for Caucasians. Among college freshmen, family support was more strongly related to institutional and goal
commitment for African Americans than Caucasians; conversely, peer support was more strongly related to institutional and
goal commitment among Caucasians. Among 15 to 29-year-olds, levels of parental support and spiritual support were higher among
African Americans than Caucasians; additionally, spiritual support was positively related to self-esteem for African Americans
but not for Caucasians. Implications and limitations of the research are discussed.
The third study was supported by National Institute of Mental Health Grant RO1 MH40963. We thank Monica Greene, Shea Lyda,

The National Conference of Catholic Bishops has argued for significant government involvement in health care in order to assure respect for what they regard as the right to health care. Critics charge that the bishops are wrong because health care is not a right. In this article, it is argued that these critics are correct in their claim that health care is not a right. However, it is also argued that the premise that health care is not a right does not imply that the market is the most equitable and just system for providing health care. Natural law arguments in the tradition of Roman Catholic social teaching lead to the conclusion that a just and prosperous society has a moral obligation to provide health care even if there is no such right. Further, there are strong moral grounds for concluding that the bishops are correct in their claim that health care ought not to be considered a market commodity. It is argued that if health care ought not to be considered a commodity, then national health insurance is the best available alternative for fulfilling the social obligation to distribute health care resources justly and fairly at this time in American history. The bishops' case for government involvement can be made on the strength of the Catholic tradition in theological argumentation, independent of the claim that health care is a right. 相似文献

Individual and institutional conflict of interests in biomedical research have becomes matters of increasing concern in recent
years. In the United States, the growth in relationships — sponsored research agreements, consultancies, memberships on boards,
licensing agreements, and equity ownership — between for-profit corporations and research universities and their scientists
has made the problem of conflicts, particularly financial conflicts, more acute. Conflicts can interfere with or compromise
important principles and obligations of researchers and their institutions, e.g., adherence to accepted research norms, duty
of care to patients, and open exchange of information. Disclosure is a key component of a successful conflict policy. Commitments
which conflict with a faculty member's primary obligations to teaching, research, administrative responsibilities, or patient
care also need attention. Institutional conflict of interests present different problems, some of which are discussed in an
analysis of an actual problem posed by two proposed clinical trials.
This paper is adapted from a lecture presented to a Symposium on Scientific Integrity, Warsaw, Poland, 23 November 1995.
Daniel Steiner was Vice-President and General Counsel of Harvard University (1972–92) and in that capacity became familiar
with conflict of interest issues. He is currently Counsel to the Boston law firm. Ropes and Gray, and is Adjunct Lecturer
in Public Policy at the John F. Kennedy School of Government. Harvard University. 相似文献

Recent studies have indicated that people describe a “good manager” in masculine terms. It was hypothesized that this could simply reflect cultural stereotypes, rather than people's perceptions of what combination of traits is desirable in a leader. In Experiments 1 and 2, subjects were presented managerial profiles ascribing all masculine, all feminine, or a combination of masculine and feminine traits (i.e., “androgynous” profiles) to hypothetical managers. Feminine-trait combinations were rated as significantly less desirable than either masculine or androgynous combinations, which were rated as equally desirable. Thus, while femininity per se was not seen as desirable in a leader, it was not viewed as a liability when combined with masculinity, a corroboration of much behavioral research on androgyny. Experiment 3 varied trait likableness and sex-role orientation. Experiments 1 and 2 were replicated for unlikable traits. Surprisingly, the opposite pattern was obtained for likable traits: the feminine combinations were rated as the most desirable, and the masculine combinations were rated as the least desirable. The results are discussed in the context of early research on impression formation and recent work on social cognition. 相似文献

The principle of hermeneutical interpretation (i.e., the art and discipline of analyzing the symbols of sacred texts) is explained and applied to the analytical group situation. It is maintained that the approach employed by this methodology provides a viable manner for understanding patients' unconscious communications. In particular, the relationship between metaphorical communication and the hereand now therapeutic experience is discussed. It is argued that the unconscious manifests itself as a set of metaphorical expressions. The paper presents two clinical vignettes illustrating how this hermeneutical methodology can aid the therapist to read the unconscious meanings of such metaphors. 相似文献

The medical humanities were organized, beginning in the late 1960s, by a small group of people who shared a critique of medical education and a commitment to vigorous action to change it. They proposed to create several demonstration programs in humanities education at American schools. Although the group began with a religious orientation, it soon acquired a broader, more secular mission. As a result of shrewd political organizing, the group attracted members from within medicine, and was awarded a grant to promote the medical humanities. This paper describes these events and sets them in the context of the social and medical history of the 1960s and early 1970s. 相似文献
