Negative physical and verbal interactions occurring between early adolescents and their closest-spaced sibling were examined. Two hundred forty-four junior high school students provided information concerning their experiences as victims and perpetrators of aggressive and agonistic behaviors. Results confirm earlier studies' findings that siblings engage in numerous hostile interactions and that females and males perform these behaviors to an almost equal extent. Participants' self-reports suggest that parents may underestimate sibling use of physical force to resolve conflicts. Findings indicate there is further need to examine sibling interactions in order to better understand family functioning and family violence.  相似文献

About 3 out of 5 Supplemental Security Income recipients have some type of unearned income. The major source of this income is Social Security benefits. Other sources are veterans' pensions, pensions from employment, asset income, and support and maintenance in-kind. This article presents for the first time detailed estimates of the distributions of these income sources, based on a 1-percent sample of May 1982 recipients. In two-thirds of the cases, the Social Security benefits were between $100 and $260 a month. Unearned income from sources other than Social Security was usually smaller. Only 5 percent of the SSI population received less tha $100 in Social Security benefits. Differences in distributions for retired-worker and disabled-worker benefits, and for widow's and children's benefits are noted.  相似文献

The commonly referenced mortality of cardiac valve replacement surgery is 2 to 5%. Some of this mortality is due to therapeutic misadventure during the procedure. Therapeutic misadventure during cardiac valve replacement may result in patterned injury of the heart, so that postmortem examination can establish the nature of the surgical injury. A case of patterned myocardial injury during valve replacement surgery is presented, with a review of literature and associated cases.  相似文献

In this qualitative study of 134 formerly abducted adolescentboys at four rehabilitation centres in Northern Uganda, theboys described their lives in rebel captivity and coping strategiesand suggested ways of reintegration. They witnessed, enduredand participated in hideous atrocities while in rebel captivity.Vigilance, absolute obedience, and cooperation with their captors;prayer and hope; denial, blaming others, constant preparednessto flee; use of traditional medicine; and resilience and perseverance,were some of the coping strategies they employed while in captivityand during escape. Once out of captivity, they suggested a reintegrationagenda sensitive to their economic wellbeing and social relationsin the context of their culture and tradition. They proposedpsychosocial activities, vocational and entrepreneurial skillstraining, provision of credit facilities, and an education systemthat recognizes their background and needs. However, all theseshould be viewed in the context of huge resource limitationsand the continuing conflict.  相似文献

Abstract

The GATT‐WTO system has been attacked for being at best indifferent to the environment and at worst hostile to it. However, rather than being an environmental foe, the GATT‐WTO system is environmentally‐friendly in many respects. Several World Trade Organization agreements — the Agreement on Agriculture, the Agreement on Technical Barriers to Trade, the Agreement on Subsidies and Countervailing Measures and the Agreement on Sanitary and Phytosanitary Measures — not only permit but encourage WTO member‐countries to implement national programs and laws to protect the environment free from WTO interference. Multilateral initiatives through organizations such as the WTO, as opposed to unilateral bullying, are the surest way of securing robust legal protections for the environment.  相似文献
