This paper reviews a variety of studies in which multi-attribute utility theory (MAU) has been used successfully to aid group decision processes and discusses the incorporation of MAU in Group Decision Support Systems (GDSS). GDSS of various levels of automation have been proposed to aid group decision making. A number of commercial GDSSs are available which are capable of aiding generation of alternatives, their evaluation, and selection. Many authors have promoted the incorporation of quantitative decision making models in GDSS. The most appropriate quantitative tool for GDSS is MAU, but MAU has rarely been utilized. The cases reviewed illustrate that the use of MAU techniques is not prohibitively difficult or complex.  相似文献

In this paper, we tested the resource dilution hypothesis, which posits that, because parenting resources are finite, the addition of a new sibling depletes parenting resources for other children in the household. We estimated growth curve models on the self‐reported parenting practices of mothers using four waves of data collected biennially between 1994 and 2000 on a nationally representative sample of 2,082 Canadian children aged 2 to 5 at initial interview and in continuously intact, two‐biological‐parent households. Results showed that when new children were added to the household, mothers exhibited declines in positive interaction, but increased their levels of consistent parenting. Taken together, these findings suggested that parenting resources were reallocated, rather than diluted, when family size increased.  相似文献

A qualitative analysis of 51 matches between volunteer mentors and pregnant adolescents is discussed in terms of problems that occurred and reasons relating to early termination of the match. In each of three stages of the relationship, different issues related to the behavior and interpersonal process between members of the match created problems. In stage one, the mentors had difficulty establishing the match when there was avoidance, distrust, and testing behavior on the part of the mentee. Fear of intimacy and rejection seemed to underlie these relationship difficulties. In stage two, which encompassed the birth of the adolescent’s child, conflict occurred when mentees’ demands overwhelmed the mentors. In the third stage, difficulties discussing termination or continuation of the relationship led to disengagement and less frequent contact. Recommendations are provided to help mentors and mentees navigate the problems in each of these stages.  相似文献

This study compared the total amount of training time and total number of trial blocks for individuals with severe developmental disabilities to acquire mands under control of unconditioned establishing operations and mands under control of transitive conditioned establishing operations for manual sign and for the Picture Exchange Communication System (PECS). Also examined was the generalization of mands across settings and communicative partners, as well as the emergence of untrained tacts and intraverbals for mands acquired using PECS. Mands for preferred items and for items needed to complete a chained task were acquired more rapidly and in fewer training blocks for PECS than for manual sign. Moreover, mands established using PECS generalized across settings and communicative partners. Finally, untrained tacts and intraverbals using PECS were shown to emerge for some of the participants following PECS training. These results suggest that PECS may be a viable alternative communication system for adults with severe developmental disabilities who have little or no history of systematic instruction and limited imitative repertoires.  相似文献

In response to a growing diversity of opinion regarding educational models and essential content in clinical social work education, this paper offers a perspective concerning graduate clinical curricula. Part I, the foundational piece of the paper, discusses the definition of clinical social work, social work’s core orientation and values, and influential contextual issues. The interrelated core orientations guiding knowledge and skill development are identified as the person-in-situation perspective and the concept of relationship. Based on this foundation, Part II identifies elements of a contemporary biopsychosocial knowledge base and essential clinical skills. This paper is intended to stimulate dialogue about a topic of importance to the profession and the clients it serves.  相似文献

In extending Durkheimian thought on the relationship between deviance and social order, Erikson (1966) advanced the constancy of crime hypothesis, maintaining that the volume of deviant behavior remains stable over time. Erikson's data for Essex County do show remarkable stability for the years 1651–1680 in the reported offender rate. However, Essex County represents a very limited test of the hypothesis. We present comparative historical data for the entirety of Plymouth Colony, 1633–1679, finding that change—not constancy—best characterizes the evidence. The lack of unequivocal support for the hypothesis suggests a need for its rethinking. Several such possibilities are briefly discussed.We wish to thank our colleagues David L. Smith, Charles J. Dudley, Michael Hughes, Richard Schuster, Alan C. Acock (Sociology), A. Roger Ekirch (Department of History) and the anonymous reviewers ofQualitative Sociology for their helpful suggestions on a prior version of this paper. The research was made possible by a small project grant from VPI & SU, and we gratefully acknowledge the assistance of Catherine L. Hammond in completing the investigation.  相似文献

Gaze is one of the main means of communication in young infants, and it has been shown to be important for subsequent socio‐emotional and cognitive development. Maternal depression is a well‐known risk factor for disrupting mother–infant interactions, but findings regarding gaze behavior in infants of depressed versus nondepressed mothers have been ambiguous. In this study, we examined gaze duration and activity in a sample of 27 infants of mothers with postpartum depression (PPD) and 49 infants of nondepressed mothers. Maternal depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale, and diagnoses were confirmed in clinical interview. Infant gaze was assessed during 4‐month face‐to‐face interactions using continuous timed‐event coding with high temporal resolution. Although we found no differences in gaze duration, infants of PPD mothers had both significantly less Gaze On and also less Gaze Off events. Findings suggest that PPD is related to reduced gaze activity during mother–infant interaction in 4‐month‐olds. This reduced activity may have long‐term negative consequences for child development.  相似文献
