Trauma, coping resources, and family functioning in emergency services personnel: A comparative study

In this study a sample of male, shift-working, operational ambulance officers were compared with a group of male shift-workers from a range of occupations in which exposure to traumatic events was not inherent in the role ( N = 71). Three dimensions of family functioning were examined: intimacy, conflict, and parenting styles, with respect to occupational type (i.e. work-related exposure to trauma) and accounting for personal resources (coping). Personal resources were found to have a significant impact on the dimensions of family functioning. Furthermore, differences emerged in the pattern of coping between the two groups. Ambulance officers demonstrated a more varied repertoire of personal resources than the control group. Social support was found to be the sole predictor of intimacy and conflict levels in the control sample. However, in the ambulance group social support was predictive of intimacy levels, rational-cognitive strategies were predictive of conflict levels, and self-care, social support, and rational-cognitive strategies were all significantly correlated with the three dimensions of family functioning.     

Child sexual abuse in Leeds before and after Cleveland

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.     

Researching the arts

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.     

Estimation of the mutagenic potency of environmental chemicals using short-term bioassay

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.     

Extreme-value analysis of canadian wind speeds

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.
