Developments in modern medical technology force many questions upon the health professions and the public. To what extent should technology be used to extend life when doing so seems futile, perhaps brutal? Who should decide such questions? What options should be available? Conditions in which such questions arise are often chaotic because of the nature of illness and treatment and because many extremely important issues in life have been poorly deliberated by the health professions and the public. This essay is an attempt to clarify some of the issues.  相似文献

This article uses interviews and Internet data to examine social media use among nonprofit organizations and county departments involved in the delivery of human services in a six‐county area in south‐central New York State. Social media use was modest, with nonprofit organizations much more likely to use it than county departments. Organizations used social media primarily to market organizational activities, remain relevant to key constituencies, and raise community awareness. Most organizations either had a narrow view of social media's potential value or lacked a long‐term vision. Barriers to use included institutional policies, concerns about the inappropriateness of social media for target audiences, and client confidentiality. Findings build on recent research regarding the extent to which nonprofit organizations and local governments use social media to engage stakeholders. Future research should investigate not only the different ways organizations use social media but also whether organizations use it strategically to advance organizational goals.  相似文献

The purpose of this study was to examine the nature and extent of mutual violence among a sample of pregnant and parenting Latina adolescent females and their partners. The sample consisted of 73 Latina adolescent females between the ages of 14 and 20 who were referred to a community-based organization for case management, education, and psychosocial support for pregnant and parenting adolescents. They completed the Conflict Tactics Scale (CTS-2) as part of a pretest to evaluate this intervention program. A small number (12 out of 73; 16%) reported no use of aggressive conflict tactics. Eighty-four percent (61 out of 73) of the study respondents reported using at least one form of minor psychological aggression and 62% (45 out of 73) reported using at least one form of minor physical assault over the past 6 months. Mutuality of conflict was high, especially in cases of minor assault by partner. There was no difference in severity or chronicity of conflict between those who were pregnant and those who were not. Female respondents reported that they and their partners engaged in comparable levels of sexual coercion. Discussion of the context of psychological, physical, and sexual aggression in adolescent relationships suggests alternative approaches to prevention of intimate partner violence among adolescents.  相似文献
