Fear of victimization may have consequences for subjective well-being. I develop and test a model linking fear of victimization to subjective health. I hypothesize that two processes link fear to subjective health-psychological and behavioral. Specifically, I hypothesize that fear of victimization increases psychological distress, and fear decreases outdoor physical activity, especially walking. High levels of psychological distress and low levels of walking, in turn, are associated with poor self-reported health. I find empirical support for the hypothesized processes in a representative national sample of 2031 adults aged 18 to 90 interviewed by telephone in 1990. The negative association between fear and health is explained largely by psychological distress and walking. However, a significant direct effect remains. I conclude with suggestions for future research linking crime and health, focusing on the need for collecting information on community disorganization. Community context is likely the ultimate exogenous variable-the one that sets in motion the destructive cycle of fear, distress, inactivity, and poor health described here.  相似文献

Stab wounds were made in parenchymatous organs (e.g. liver, spleen, kidneys, lungs) using a variety of instruments. The shape of the resulting canal was investigated by X-ray analysis after introduction of an X-ray contrast medium. The best contrast was obtained using a contrast medium containing barium. The shape of the canal gave a direct representation of the outline of the instrument used. The width of the canal was however, always several millimeters smaller than the corresponding blade of the instrument. The position of the blade back in single-edged blades could be demonstrated with stronger contrast.  相似文献

Conclusion With the passage of the Administrative Dispute Resolution Act, the stage was set for innovation and change in federal agencies. Now, part way into the five-year life of the Act, a new administration has the potential to encourage even wider use of ADR at the federal level, providing still more examples from which to develop a clearer sense of best practice. Additional funds, both for ACUS and individual agencies, are vital to providing the level of experimentation, innovation, and documentation needed to ensure success.MIT ProfessorLawrence E. Susskind is director of the MIT-Harvard Public Disputes Program, 512 Pound Hall, Harvard Law School, Cambridge, Mass. 02138.Eileen F. Babbitt is associate director of the Public Disputes Program.Phyllis N.
