Duty to Warn and Intervention with HIV-Positive Clients

Complex ethical and legal issues are involved when an HIV-positive client presents a danger to others as a result of engaging in unprotected sex or needle sharing. This article presents a detailed assessment-and-intervention model that is based on the integration of ethical and legal principles with information about the level of risk associated with a client\u27s behavior, the HIV status of the client, and the sexual or needle-sharing partner\u27s awareness of the client\u27s HIV status. Appropriate interventions, including the duty to warn, are identified for each of the risk levels

An efficient representation for kernels in the 2d dynamics displacement discontinuity method for cracked elastic materials

The displacement discontinuity method is a rather standard approach to study cracks in elastic materials. This is in fact a certain technique to construct the system of Boundary Integral Equations (BIE), or equivalently, Boundary Element Methods (BEM). In the static case this typically results in explicit expressions for the kernels of respective BIE, both in 2d and 3d problems. In the work the authors give efficient representations for such kernels in explicit form

Religion, politics, and the environment in rural America

Reflecting the heterogeneous nature of rural America, rural Americans are divided primarily along religious lines on their perspectives of environmental conservation and climate change. And as rural voters and environmental issues become key issues in the upcoming presidential election, this religious divide presents a challenge to political candidates
