燃气安全小常识

<正>燃气给人们的生活带来了方便,但燃气具有易燃、易爆、易中毒等特性,使安全用气的问题也越来越突出。燃气中毒、死亡事故屡有发生,给家庭造成了不幸,给社会带来了压力。究其原因,主要是使用者缺乏必要的燃气安全使用常识及使用不当造成的。因此,掌握日常安全用气常识,加强自我保护意识,对每个用户都十分重要。

Accounting for unsafe sex: Interviews with men who have sex with men

Semi‐structured one‐on‐one interviews with 102 gay and bisexual men were conducted to examine the reasoning processes men use to exempt themselves from practicing safe sex. Qualitative analysis of the interviews revealed the following recurring themes: (a) Many men who were in couple relationships avoided condom use for reasons involving intimacy or trust, or because both partners were HIV‐negative; (b) unsafe sex sometimes occurred inadvertently or involuntarily; (c) negative moods and self‐images were associated with unsafe sex; (d) by “intuiting” that their partner was HIV‐negative, participants exempted themselves from the need for safe sex; and (e) when the boundary between safe and unsafe was unclear, participants used a combination of unofficial and official guidelines to determine what is safe.

The Good Life: Moral and Ethical Sexual Considerations

There are an enormous number of studies surrounding predictors of condom use, and an equally impressive number of prevention programs in place to decrease the rate of HIV transmission. Despite such attention, the incidence of HIV infection remains high. One contributing factor to the continued spread of HIV may be the relative absence of recognition by researchers that condoms are imbued with a social meaning that threatens two salient goals for interactants: the desires to maintain positive identities and close relationships. Recent evidence suggests that requests to use a condom may be interpreted in ways that threaten both goals. This investigation examines the roles of identity and relational maintenance goals as influences on safe‐sex decisions. Results from an experimental design confirm the importance of these goals to safe‐sex behavior. Implications are noted and suggestions for changes in prevention programs offered.     

Fracking Fortunes: Economic Well‐being and Oil and Gas Development along the Urban‐Rural Continuum

Oil and gas extraction, especially via unconventional means like hydraulic fracturing, is hailed as an economic boon by many commentators and political leaders. However, empirical evidence is limited. In this article, we consider the socioeconomic effects (particularly, related to poverty, employment, income, and wages) of unconventional oil and gas extraction using a national data set of U.S. counties. We use a novel between‐ and within‐county random effects modeling strategy to capture both resource curse and boomtown dynamics. Further, we allow the effect of oil and gas development to be conditioned by county rurality. Broadly, our findings suggest that oil and gas development has very complex effects at the county level. Within‐county growth in oil and gas production slightly improves most economic outcomes, but counties that specialize in oil and gas development tend to perform worse than other counties. We find that, in general, the effect of within‐county oil and gas production is not significantly moderated by county rurality.     

Positive Youth Development and Foster Care Youth: A Digital Perspective

The virtual world of the Internet may be used to support positive youth development. Accessing resources in educational, employment, health, and social domains is enhanced by the ability to effectively use digital technology. Foster youth are at risk for poor developmental outcomes and may face barriers to competent use of the Internet. We discuss the benefits and risks of Internet use and the importance of digital literacy to protect against risks, and we offer suggestions on ways that child welfare agencies, case managers, and foster parents can work with youth to support safe and effective use of digital technology.
