This paper provides a perspective on spouse abuse from an ecosystemic approach suggested by second order cybernetics. An attempt is made to demonstrate the interactional basis for an understanding of spouse abuse and to suggest that the failure to use an ecosystemic perspective may result in therapists and other helpers inadvertently exacerbating the problem. Borrowing from the work of Keeney and Bateson, an analysis of the relational aspects of the problem of spouse abuse is provided which illustrates the similar nature of typical intervention strategies to the problem.The ideas discussed in this paper were developed while the author was a therapist at the Family Therapy Clinic at Texas Tech University. Appreciation is expressed to Monte Bobele, Bradford Keeney, and Thomas Conran for the helpful comments and ideas provided during the preparation of this paper.  相似文献

This paper reports on exploratory research and therapeutic work with a neglected but highly important family triangle, the grandmother-mother-daughter triangle. Some characteristic relationships are described from a clinical sample of 18 daughters for whom such a triangle was important. The triangle may signal both problems and strengths for therapy and the daughters.  相似文献

The word frequency effect (WFE) has been taken as evidence that recall and recognition are in some way fundamentally different. Consequently, most models assume that recall and recognition operate via very different retrieval mechanisms. Experiment 1 showed that the WFE reverses for associative recognition, which requires discrimination between intact test pairs and recombinations of study list words from different study pairs. Experiment 2, in which word triples were used, revealed an interaction between word frequency and test type: for item recognition, performance was better for low-frequency words; however, for associative recognition and free recall, performance was better for high-frequency words. In Experiment 3, item recognition was tested: although overall performance was better for low-frequency words, the recognition advantage for items in intact pairs was larger for high-frequency words, suggesting two components in recognition memory. These results imply common mechanisms in recall and recognition. Theoretical implications are discussed within the framework of the SAM model.  相似文献

This paper describes the development and validation of a physical performance test battery to select high pressure cleaning workers at Tennessee Eastman Company. The research uses a concurrent, criterion-related validation strategy to demonstrate the relationship between test performance and job performance. The study proceeded through four stages, with data collected in one stage used in subsequent stages. The two types of predictor measures included ability tests and work sample simulations. For some analyses, the work sample simulations were also used as criteria. Four samples of incumbents (N=63) were tested on all experimental measures. Using criterion groups of successful incumbents and unsuccessful former incumbents (N=33), all of the work simulation tests and the ability-referenced tests were significant predictors of successful versus unsuccessful job status. In addition, the ability tests predicted performance on the work sample simulations, particularly for those requiring strength and endurance. A battery of three ability tests resulted in R=.68 for job status and in R=.43, .73, .80, and .84, respectively, for each of the work sample simulations. Two of the three ability tests in the final test battery are likely to result in adverse impact against females. However, data collected on female maintenance technicians indicated women, as a group, would not be screened out categorically as a result of implementing the physical ability test battery.  相似文献

Accountability in a computerized society   总被引:2,自引:0,他引:2  
This essay warns of eroding accountability in computerized societies. It argues that assumptions about computing and features of situations in which computers are produced create barriers to accountability. Drawing on philosophical analyses of moral blame and responsibility, four barriers are identified: 1) the problem of many hands, 2) the problem of bugs, 3) blaming the computer, and 4) software ownership without liability. The paper concludes with ideas on how to reverse this trend. Several people have contributed generously to this work. Michael Davis, Deborah G. Johnson, Arthur Kuflik, Pamela Samuelson, Debra Satz, Richard De George, Larry May, and Dennis Thompson read drafts and made invaluable suggestions. Reviewers forScience and Engineering Ethics offered thorough and challenging commentary. An earlier version of the paper was presented at The American Philosophical Association, Eastern Division Meeting, December 1993, where audience comments and questions led to clarification of several key issues.  相似文献

The present study assessed the prevalence and impact of social phobia and other anxiety disorders in disabled workers with chronic musculoskeletal pain. Potential participants were 200 disabled workers consecutively referred to an interdisciplinary tertiary care centre. A two stage screening process was used in which: (a) a self-report battery was given during a pre-admission visit, and (b) preplanned selection criteria were applied to the self-report instruments to select patients for a structured diagnostic interview. Fifty-four of the 146 patients who provided complete responses on the self-report battery met criteria for interview. Twenty-six patients (17.8%) met DSM-IV criteria for a current anxiety disorder and, of these, 16 (11.0%) were diagnosed with social phobia. Subjects with social phobia rated themselves as having less social support than subjects with no psychiatric disorder, but the groups did not differ in pain-related life interference, personal control, or health care utilization. The results suggest that social phobia is over-represented in disabled workers with chronic musculoskeletal pain and should be noted as a comorbid condition that may compound both suffering and disability.  相似文献

This study examines the degree to which mothers perceive infants as intentional and the relations among perception of intentionality, background variables, maternal emotional adjustment, and maternal interactive style. Forty mother-infant dyads were assessed when the infants were 4 months old, and 34 were retested at 8 months. Parent perception of infant intentionality (PPII) was measured via a rating of videotaped segments of infant behavior and an interview. Intentionality scores showed acceptable internal consistency and were positively intercorrelated at each age and across age. The two measures were aggregated to form an index of PPII at each age. Higher educational attainment was associated with lower PPII scores, experience with infants was associated with higher PPII scores, and academic knowledge about child development was not related to PPII. Mothers with more symptoms of anxiety had lower PPII scores, but high maternal separation anxiety was associated with higher PPII scores. Maternal symptoms of depression had a complex relation to PPII scores. Mothers rated as sensitive in mother-infant interactions had higher PPII scores. These variables accounted for 34% of the variance in PPII at 4 months and 49% at 8 months. There were also group differences: Mothers of 8-month-olds had higher PPII scores than mothers of 4-month-olds, mothers of girls had higher PPII scores than mothers of boys, and mothers attributed more intentionality in episodes with girls than in episodes with boys. The results are discussed in relation to mechanisms whereby PPII interacts with aspects of the parent and infant.  相似文献
