Within the framework of the interpersonal view of depression, this article examines the linkage between depression and four aspects of marital relationship: stress, support, role expectations, and interactional dynamics. Acknowledging the intertwined relationship between depression and marital adjustment, existing models of martial therapy for married depressed patients are examined for the extent to which they address these four aspects. The empirical evidence for the efficacy of these models is also reviewed, suggesting elements of marital therapy that are conducive to effective treatment outcome. 相似文献

Forty married couples participated in a randomized trial comparing 8 weekly sessions of emotion-focused therapy (EFT) for couples to a group of couples who were placed on an 8-week waiting list. A composite marital satisfaction score was created from scores on the Dyadic Adjustment Scale, Positive Feelings Questionnaire, and Personal Assessment of Intimacy in Relationships scale. Controlling for pretest scores, participants in the treatment group had significantly higher levels of marital satisfaction after 8 weeks than wait-list participants. Supplementary analyses identified variables associated with gains in therapy and with dropping out of the study. 相似文献

OBJECTIVES: Identify associations between lack of formal boater training, drinking and boating, and other unsafe boating practices. METHODS: A telephone survey queried respondents (age 16 or older in continental United States) about boating experience, type of boat used, and training. RESULTS: Of the 3,042 boaters surveyed (70% response), most had no formal training (73%). Boaters with formal training failed to use PFDs about as often as those without formal training and were equally or more likely to use alcohol while boating. CONCLUSIONS: The unexpected association between formal training and unsafe boating practices is probably due to reduced risk perception and inadequacies of boater training programs. Such programs seldom mention the risks of alcohol use while boating. Decisions to mandate formal training should be informed by these results; if mandated, training should address the risks of alcohol use while boating, and should be renewed frequently enough to offset reductions in risk perception. 相似文献

One form of error that can affect census adjustments is correlation bias, reflecting people who are doubly missing--from the census and from the adjusted counts as well. This article presents a method for estimating the total national number of doubly-missing people and their distribution by race and sex. Application to the 1990 U.S. census adjustment leads to an estimate of 3 million doubly-missing people. Correlation bias is likely to be a serious problem for census adjustment in 2000. The methods of this article are well suited for measuring its magnitude. 相似文献

This study examines the effectiveness of social support networks on psychological well-being among 602 homeless and runaway adolescents. The respondents were interviewed in shelters, drop-in centers, and on the streets in cities of four Midwestern states (Missouri, Iowa, Nebraska, and Kansas). The path model was used to test the direct effect of family abuse and precocious independence on adolescent depressive symptoms and indirect effects through social support networks. Results indicate that although abusive family origins contribute directly to depressive symptoms there are indirect effects of family abuse and early independence through social support networks. Family abuse and early independence drive homeless adolescents to rely on peers for social support. While support from friends on the street reduces depression, association with deviant peers increases depression. 相似文献

The wireless network jamming problem 总被引:1,自引:0,他引:1
Clayton W. Commander Panos M. Pardalos Valeriy Ryabchenko Stan Uryasev Grigoriy Zrazhevsky 《Journal of Combinatorial Optimization》2007,14(4):481-498
In adversarial environments, disabling the communication capabilities of the enemy is a high priority. We introduce the problem
of determining the optimal number and locations for a set of jamming devices in order to neutralize a wireless communication
network. This problem is known as the wireless network jamming problem. We develop several mathematical programming formulations based on covering the communication nodes and limiting the connectivity
index of the nodes. Two case studies are presented comparing the formulations with the addition of various percentile constraints.
Finally, directions of further research are addressed. 相似文献
