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

Ninety-five high-risk adolescents were studied to determine whether their dating aggression and its justification as a response to interpersonal problems were specific to the current partner, general to dating relationships, or part of a global age-mate (same-sex peers and opposite-sex dating partners) aggression problem. Approximately one-third of males and two-thirds of females reported physical aggression against their current dating partner. Males' aggression (and its justification) toward their current dating partner was part of a generalized pattern of dating aggression, whereas for females, physical aggression against a current dating partner (and its justification) was partner-specific and unrelated to aggression in other relationships. Findings are discussed with regard to intervention and future research on adolescent dating aggression. 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.

Therapists and parents were given vignettes describing the behavioural and emotional difficulties of two nine-year-old children and were asked to rate the importance of a number of possible explanations for such difficulties. Broad agreement was found between parents and therapists, but also there were a number of significant differences. Parents endorsed more child centered explanations and put greater emphasis on physical and developmental factors, while therapists endorsed relationships factors and saw the beliefs of other family members as important. Therapists who were parents showed a pattern of responses that lay between those of parents and non-parent therapists. 相似文献

The 30-item Trainee Adjustment to Program Stress (TAPS) scale was developed to measure lifestyle stress of family therapy trainees. Initially, 70 items were generated from propositional statements based on four constructs. Following pilot testing, 329 out of 900 (37%) student members of the American Association for Mariage and Family Therapy (AAMFT) returned TAPS questionnaires. Internal consistency reliability analyses and principal components and factor analyses produced a final 30 item TAPS scale appropriate for use in family therapy training programs. Reliability and validity measures are reported. 相似文献

Examination of boundary regulation can provide family therapists with a framework to describe both the functioning of family systems and personal systems (i.e., the intrapsychic functioning of individual family members). In the present study, late adolescents' perceptions of boundary regulation within their family systems (i.e., ratings of family health, communication, leadership, expressiveness, cohesion, and family conflict) were related to regulation of their personal boundaries (i.e., self-reported personal competence, distress, and patterns of defense mechanism use). In addition, personal system variables reliably discriminated between adolescents who described their families as psychologically healthy versus psychologically unhealthy. 相似文献

Family therapists face a significant rhetorical challenge in working with families that disagree about the problematic life-situation which brought them to therapy. Therapists must find a way to join with disagreeing family members and then find a way to engage in a therapeutically useful conversation with them. Thus, they must deal resourcefully with contradictions. This article explores the ways that the Sophistic rhetorical concept of antilogic may be employed in helping therapists join and then engage in a therapeutically useful conversation with families who hold contradictory views concerning the problem that brought them to therapy.The author wishes to thank Ronald Chenail, PhD, Douglas Flemons, PhD, and Shelly Green, PhD, for their assistance in the development of this project. 相似文献

The author presents an argument for tolerance, mutual understanding and reconciliation in psychotherapy, instead of a continued emphasis of schools. Psychotherapists' work with clients is proposed as a likely area for mutual understanding, rather than continued emphasis on their particular theories and academic matters. Psychotherapeutic intervision groups in which a small number of therapists voluntarily discuss their cases with peers from various backgrounds have become increasingly common again in recent years.Slightly revised version of a presentation made at the Georgetown Family Center Symposium in November 1995. 相似文献

This paper investigates how organizational climate and information quantity influences choice of decision making strategies. A simulated company with an organizational climate was manipulated to be either supportive or non-supportive of participative decision making methods. Subjects then solved problems in which information available to make a decision was manipulated. Results indicated that climate has an effect on choice of decision making strategies independent of information quantity. A second study was then conducted to assess how the climate manipulation affected subjects' decision-making. Organizational climate information appears to affect decisions in a manner analogous to Tversky and Kahneman's (1981) decision framing model.The contribution of each author is equal for this paper. The order of authorship was determined by a coin flip. This research was supported by Ohio Board of Regents and University of Akron Faculty Research grants to the second author. Portions of this paper were presented at the 1989 Society of Industrial Organizational Psychology Meetings and the 1991 Association of Management Meetings. 相似文献

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
