This paper examines the author's treatment of a severely depressed mother–infant pair in a therapeutic nursery. While the direct treatment lasted only nine months, a telephone relationship has continued over fifteen years. Dramatic changes in the pair resulted from the strong therapeutic alliance between mother and therapist, combined with a flexible and adaptive approach, utilizing on demand availability, as described by Winnicott. The convergence of the clinical work with the maturational processes and the sequelae of both mother and infant's early experiences of deprivation are described and explored.  相似文献

The practice of chlorine disinfection of drinking water to reduce microbial risks provides substantial benefits to public health. However, increasing concern around potential risks of cancer associated with exposure to chlorinated disinfection byproducts confuses this issue. This article examines the science agenda regarding chlorinated disinfection byproducts (CDBP) and cancer in Canada and the United States, focusing on the social construction of scientific knowledge claims and evidence. Data for this analysis were obtained from published documents as well as from in-depth interviews with epidemiologists and toxicologists centrally involved with the issue in both countries. Results of the analysis suggest that toxicological scientists want to close the door on the "chloroform issue" due to increasing evidence that chloroform is safe at low doses, because epidemiological scientists can no longer move forward the cancer science until significant improvements can be made in assessing human exposures, and because the scientific foci of research on DBP have shifted accordingly. Further, a distinction emerges in terms of how scientific uncertainties are interpreted when they cross-cut disciplines in the context of human health risk assessment. We suggest this tension reflects a balance of how uncertainty and authorities are managed in a mandated science-policy domain. Sufficient evidence was provided to keep the DBP issue on the regulatory agenda and to generate additional research, yet authorities and concomitant interpretations of uncertainty were contested. Such science generation and contestation inevitably influences complex risk assessment processes with respect to what water-related health risks are addressed and how.  相似文献

The impacts of social networks on changes in contraception in rural Kenya are investigated using special data from a longitudinal household survey. An analytic model, informed by detailed knowledge of the setting, yielded estimates that indicate that (1) social networks have substantial effects even after unobserved factors (e.g., homophily) that may determine social networks are controlled; (2) controlling for these unobserved factors may substantially alter the estimated effects of networks (these controls were not used in previous studies); (3) network effects are important for both men and women; and (4) network effects are nonlinear and asymmetric, suggesting that networks provide information primarily through social learning, rather than by exerting social influence.  相似文献

We describe a quantitative methodology to characterize the vulnerability of U.S. urban centers to terrorist attack, using a place-based vulnerability index and a database of terrorist incidents and related human casualties. Via generalized linear statistical models, we study the relationships between vulnerability and terrorist events, and find that our place-based vulnerability metric significantly describes both terrorist incidence and occurrence of human casualties from terrorist events in these urban centers. We also introduce benchmark analytic technologies from applications in toxicological risk assessment to this social risk/vulnerability paradigm, and use these to distinguish levels of high and low urban vulnerability to terrorism. It is seen that the benchmark approach translates quite flexibly from its biological roots to this social scientific archetype.  相似文献

This report examines the status of Midwest women sociologists in occupational attainment and professional participation, and seeks to answer three questions: (1) What is the current status of Midwest women sociologists? (2) What changes have occurred in the status of Midwest women sociologists in recent years? and (3) How does the status of women sociologists in the Midwest compare to their colleagues nationally?  相似文献

Despite lower victimization, older people express greater fear of crime. The causes and consequences of such fear are investigated for a 1980 sample of 1,185 persons aged 60+. Fear of crime is a response to both personal vulnerability and locational cues. Fear reduces subjective well-being, but has little relation to activity patterns. While social resources have little bearing on fear of crime and its consequences, variations by sex and personal competence are apparent. These reflect the role of coping resources and environmental docility.  相似文献

Comprehensive medical and mental health evaluations of children in foster care are recommended within 30 days of entering care. What constitutes a comprehensive evaluation has yet to be established. This study examines the need to include educational assessment as a component of the comprehensive evaluation. Rates of achievement and language problems for Arkansas school-age children are compared with rates of medical and psychiatric disorders to assess the relative need for including educational assessment.  相似文献

In this paper I examine the association between subjective time pressure and depression and consider whether time pressure mediates the relationship between roles and depression, whether social and economic resources moderate the association between time pressure and depression, and whether time pressure explains gender differences in depression. Results of a telephone survey of 790 respondents indicate that time pressure is significantly associated with distress for men and women, and that subjective time pressure accounts for the significantly higher depression of employed women. Time pressure mediates the impact of housework and the volunteer role among women and it partially explains the differential depression of divorced men. Several resources moderate the impact of time pressure on depression: income among both men and women and perceived co-worker social support among men. Results suggest that the subjective experience of time pressure can be thought of as a potentially important mechanism by which lived experience is transformed into depression. However, in spite of the ubiquity of time pressure in the North American context, the depressing consequences of this subjective experience are not distributed equitably, suggesting that the capacity to manage time pressure and avoid depression may be another benefit associated with strategically advantageous social locations.  相似文献

In contrast to tobacco, alcohol, and other consumer products associated with health risks, we know very little about how firearm manufacturers advertise their products. The authors examined advertisements for firearms in all 27 ad-accepting magazines listed in Bacon's Magazine Directory "guns and shooting" category. Sixty-three manufacturers spent an estimated $1,195,680 on firearm advertising during the month studied. Annual advertising costs ranged widely; manufacturers spent an estimated $28.16 in advertising per firearm produced. Firearms generally were presented as a part of a lifestyle. Self-protection was noted infrequently in the advertisements. By contrast, attributes of the gun, typically technological characteristics, were noted in almost every advertisement.  相似文献

Rational emotive behavior therapy: disputing irrational philosophies   总被引:1,自引:0,他引:1  
This article provides an overview of the concepts and techniques of rational emotive behavior therapy to distinguish it from cognitive-behavioral therapy. Rational emotive behavior therapy proposes that psychological disturbance is largely created and maintained through irrational philosophies consisting of internal absolutistic demands. This therapy strives to produce sustained and profound cognitive, emotive, and behavioral change through active, vigorous disputation of underlying irrational philosophies.  相似文献
