In this study, the most salient worries of Dutch adolescents are examined and the most often reported symptoms are ranked. The relationship between worrying and health is explored using structural modeling as are the frequently found gender differences in these areas. Worrying is postulated as an indicator of psychosocial well-being along with affectivity, ease of parental communications, tiredness, and loneliness. Health, or physiological status, is indicated by reported symptoms, frequency of doctors visits, aspirin consumption, and a global health measure. Four hundred and sixteen high-school students (211 girls and 205 boys) fitted in a questionnaire during school hours. The structure of the bet fitting model was the same for boys and girls, indicating that gender differences are a question of degree, and not of different structural relationships. Psychosocial well-being explained 77% of the variance in physiological status. The implications of the findings for health education are discussed. 相似文献

Selenium is a ubiquitous element in the environment essential to the human diet and widely utilized in industrial processes. Fatal human selenium intoxication is rare. The authors report a case in which investigators recovered a bottle of gun-bluing agent beside a 24-year-old man. He exhibited signs and symptoms typical of acute selenium intoxication presenting with nausea and vomiting, followed by pulmonary edema and rapid cardiovascular collapse approximately 3 to 4 h after ingestion. Classic electrocardiographic (EKG) changes, which have been reported to occur in acute selenium intoxication, included sinus tachycardia with ST wave alteration. Toxicological results confirmed elevated blood and tissue concentrations. The cause of death was ascribed to acute selenium intoxication, which ensued rapidly after oral consumption. The manner of death was suicide. This case report, which presents an overview of acute and chronic selenium poisoning, underscores the value of thorough toxicologic analyses of tissue and body fluids in humans. 相似文献

In the past decade, juvenile justice agencies have become more reliant on objective risk scales based on an actuarial approach to assessing risk. Risk assessment scales are used as decision-making guides at multiple points in the juvenile justice system. However, little research has focused on assessment of more serious offenders facing removal from the community. Enormous benefits can be derived, both in public safety and cost savings, from successful interventions with these offenders. Identifying offenders most amenable to intervention and at lowest risk for offending upon leaving placement represents a significant challenge. In this study, a placement risk screen was developed that assesses amenability to treatment in a residential treatment program and later risk for adult criminality. The relationship between suspected risk factors, success in a residential treatment program, and adult offending was assessed in a population of 81 male delinquent youths. Many factors are believed to have a bearing on success in treatment and later offending behavior, but only a small number of these were statistically significant. The results suggest that success in residential placement can reduce future offending, but that youth should first be screened for amenability to the program so scarce resources can be conserved. The proposed placement risk screen can assist juvenile court judges, officers, and residential treatment staff in identifying youth most suitable for treatment and who represent a lower risk to the community. 相似文献

This study investigates the longitudinal political and administrative problems associated with federal–local government relations. The findings demonstrate four primary challenges of the system of federal grants-in-aid that hinder the relationship of policy design at the federal level and policy implementation in local communities: the politics of decentralization, subnational capacity, program accountability and program adaptability. A case study of the Community Development Block Grant, as assessed by the Advisory Commission on Intergovernmental Relations and the General Accounting Office between 1974 and the present, is included to demonstrate the application of these problems within the system. Although the "evolution of devolution" can greatly benefit the recipients of public services at the local level, it often operates within an unorganized and ineffective system that public managers at all levels of government must continue to develop. 相似文献
