We report a retrospective cohort study in which clinical and outcome features of 237 cases of child sexual abuse diagnosed by Leeds paediatricians after Cleveland in 1989 were compared with previously published characteristics of 337 children diagnosed by the same paediatricians before Cleveland in 1985 and 1986. Clinical and diagnostic features also were analysed in two subgroups of the 1989 cohort, those for whom there was no case conference and those in whom further abuse was detected at follow-up examination. The number of cases diagnosed annually remained high, and source of referrals and age and sex distribution were similar. Most suspected perpetrators were from within the home in both cohorts. Some clinical features of the 1989 cohort suggested more physically severe abuse. In 1989 fewer children were registered as sexually abused, or were taken into care, and fewer suspected perpetrators were convicted. From the 1989 cohort those children for whom there was no case conference tended to be older, to disclose and were abused less severely by someone outside their home as compared to those for whom a case conference was held. The children in whom further abuse was detected tended to be younger, to not disclose. to be more severely abused by a perpetrator within the home and to be taken into care as compared to those in whom further abuse was not detected. One or more case conferences were held for nearly all of the children in whom further abuse was detected. For most of the 1989 children no evidence was found indicating receipt of mental health services from other than the key social worker. Implications of these findings are discussed in terms of professional and public knowledge and attitudes regarding children's and parental rights and family preservation. 相似文献

As the social, economic, educational, political, and international significance of the creative arts is increasingly recognized by American society, the need for insightful research on the arts, their organization, production, and impact becomes more evident. But the diversity of arts disciplines and organizations can make it difficult for the researcher to identify and locate useful and reliable information on the arts. This article provides a broad summary of resources available to scholars and practitioners to inform their research on artists, arts organizations, audiences, and arts support systems. 相似文献

The Ames Salmonella test is a widely used bioassay method for assessing the mutagenic potency of a potential carcinogen. The test is quick and reliable, and exploits the correlation that exists between mutagenic potential and carcinogenic potential. The data for this case study came from an international study involving 20 laboratories in nine countries. The laboratories participated in a designed experiment in which substances (complex chemical mixtures of the type encountered in the environment) were evaluated for mutagenicity using the Ames test. A stringent protocol was followed. The study's principal aim was to investigate intra- and inter-laboratory variation in test results. The data consist of counts of revertant Salmonella colonies at each of six dose levels of a substance. The data were obtained for each of five test substances from each participating laboratory. The bioassays were carried out according to a prescribed factorial experimental design. Three sets of analysts participated in this case study. They were asked to model the dose-response relationship for two substances, to develop an index of the strength of the relationship, and to assess intra- and inter-laboratory variation in bioassay results. 相似文献

Estimates of extreme winds are essential for engineering design, but in preparing such estimates major statistical issues are encountered. In this case study, the analysts were provided with hourly readings on wind speed, wind direction, and barometric pressure at five Canadian stations for observation periods ranging over several recent decades. Their assignment was to calculate point and interval estimates of 10-, 20-, 50-, and 100-year return values (i.e., upper fractiles) for the wind speeds at these stations. 相似文献

Past research has documented the fact that status characteristics organize group interaction. Freese and Cohen (1973) specified a condition under which a performance characteristic would eliminate the effect of a differentiating diffuse status characteristic. The present research extends the Freese-Cohen theory to specify a condition under which a differentiating diffuse status characteristic will eliminate the effect of a performance characteristic. Predictions derived from the formulation are (a) in situations where actors are differentiated by a diffuse status characteristic and a totally inconsistent performance characteristic, influence rates will be a function only of diffuse status and (b) it is the strength (0) of a totally inconsistent performance characteristic, rather than the number of traits comprising the characteristic, that determines its effect. These predictions are contrasted with those of other expectation states formulations (i.e., Berger et al., 1977). Laboratory experiments generally support our formulation while providing some disconfirming evidence for the other formulations. 相似文献

A high-risk population was successfully identified by the use of perinatal screening procedures. These children encountered significantly different parenting practices than the low-risk "control" group. There were also significant differences between "High-Risk" and "Low-Risk" families on issues concerning social adjustment and mother/infant attachment. Five children in a "High-Risk Nonintervene" group required hospitalization for serious injuries thought to be secondary to abnormal parenting practices. There were no such hospitalizations in either a High Risk Intervene group or a Low Risk group. Labordelivery observations, and postpartum interviews and observations provided the most accurate predictive information; prenatal interviews and questionnaires did not add significantly. Perinatal assessment and simple intervention with families at high risk for abnormal parenting practices significantly improves the infants' chances for escaping serious hospitalized physical injury. 相似文献
