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. 相似文献

Population,Development and Global Warming: Averting the Tragedy of the Climate Commons 总被引:1,自引:1,他引:0
Carbon emissions from fossil fuel use and other human activity are predicted to cause a significant warming of the global climate, according to a growing consensus of scientists. Global warming would have substantial negative effects on the world environment and economy. Human population and economic growth continue to drive both energy use and carbon emissions. While the developed countries are the largest source of present and past emissions, developing countries are rapidly catching up. China will probably surpass the United States as the largest carbon emitter early in the next century. The global warming treaty signed in Rio in 1992 relies entirely on voluntary emission caps for developed countries and has had little or no apparent effect on emissions. Much stronger steps must be taken to avoid or lessen potential climate change. A globally determined but nationally imposed carbon tax should be adopted to internalize the future costs of carbon emissions into the present cost of fossil fuel and other carbon sources. This would allow the maximum use of free market forces and individual choice to determine how carbon emission reductions are achieved. In addition, national emission caps for all countries should be established. International trade mechanisms can be used to support universal implementation of these measures. Where possible, global warming policy should include strong but equitable incentives for sustainable development and population stabilization, important goals in themselves regardless of the extent of future climate change. 相似文献

Statements such as "80% of the employees do 20% of the work" or "the richest 1% of society controls 10% of its assets" are commonly used to describe the distribution or concentration of a variable characteristic within a population. Analogous statements can be constructed to reflect the relationship between probability and concentration for unvarying quantities surrounded by uncertainty. Both kinds of statements represent specific usages of a general relationship, the "mass density function," that is not widely exploited in risk analysis and management. This paper derives a simple formula for the mass density function when the uncertainty and/or the variability in a quantity is lognormally distributed; the formula gives the risk analyst an exact, "back-of-the-envelope" method for determining the fraction of the total amount of a quantity contained within any portion of its distribution. For example, if exposures to a toxicant are lognormally distributed with σin x = 2, 50% of all the exposure is borne by the 2.3% of persons most heavily exposed. Implications of this formula for various issues in risk assessment are explored, including: (1) the marginal benefits of risk reduction; (2) distributional equity and risk perception; (3) accurate confidence intervals for the population mean when a limited set of data is available; (4) the possible biases introduced by the uncritical assumption that extreme "outliers" exist; and (5) the calculation of the value of new information. 相似文献

We show that unexpected price‐level movements generate sizable wealth redistribution in the Euro Area (EA), using sectoral accounts and newly available data from the Household Finance and Consumption Survey. The EA as a whole is a net loser of unexpected price‐level decreases, with Italy, Greece, Portugal, and Spain losing most in per capita terms, and Belgium and Malta being net winners. Governments are net losers of deflation, while the household (HH) sector is a net winner in the EA as a whole. HHs in Belgium, Ireland, Malta, and Germany experience the biggest per capita gains, while HHs in Finland and Spain turn out to be net losers. Considerable heterogeneity exists also within the HH sector: relatively young middle class HHs are net losers of deflation, while older and richer HHs are winners. As a result, wealth inequality in the EA increases with unexpected deflation, although in some countries (Austria, Germany, and Malta) inequality decreases due to the presence of relatively few young borrowing HHs. We document that HHs' inflation exposure varies systematically across countries, with HHs in high‐inflation EA countries holding systematically lower nominal exposures. 相似文献

ABSTRACTWithin NZ gambling and its associated harms are well-researched topics. However, most studies to date have relied upon the use of survey methodology or have focused on individual regions. In this paper we distribute gaming machine proceeds (GMP) from gaming venues to the surrounding localities in order to derive estimates of GMP per capita. It is hoped these estimates will enable the trusts who operate the electronic gaming machines (EGMs), and who are responsible for reinvesting a proportion of proceeds back into the community, to more accurately target funding towards the areas most affected by the harms of EGM gambling. Our estimates of GMP per capita also provide a means of assessing the criterion validity of the recently developed Dynamic Deprivation Index. Furthermore, although it is well known that Māori and Pacific Island populations have a higher incidence of problem gambling, our results imply that when controlling for socio-economic deprivation and the geographic location of EGMs the associations between ethnicity and GMP per capita are weak. From a policy perspective, this suggests the most effective way of limiting the harms of EGM gambling on these populations is to place tighter controls on the number of venues within their communities. 相似文献

Objective. The goal of this study is to examine how the political mobilization of business interests influences aggregate public policy outputs in the states. We examine the relationship between business mobilization and general state policy liberalism, as well as policy that we term state “business policy climate.” Methods. We construct a measure of the “business policy climate” from a number of tax and regulatory indicators in the states and examine whether business influences it and policy liberalism using ordinary least squares regression. Results. The analysis shows that business mobilization does not influence general policy liberalism but is a significant influence on a state's business policy climate. Specifically, the dominance of a state's campaign finance system by business interests makes policy more favorable toward business. Conclusions. The extent of business mobilization in a state is an important influence on public policy outputs but is constrained by the activities of other political actors such as unions. 相似文献

While services have been assisting women who have been victims of domestic violence for many years, it has only been in recent times, that children exposed to domestic violence have begun to receive attention by service providers as clients in their own right. A number of specialised programs have now been designed to meet the needs of these children by domestic violence services and agencies that have a child protection or child welfare/family support focus. This paper aims to describe the types of programs currently in operation across Australia which cater specifically for the needs of children who have been exposed to domestic violence by analysing programs listed on the Child Abuse Prevention Programs Database developed by the National Child Protection Clearinghouse. A number of suggestions are made with regard to the means by which therapeutic responses and research in this area could be enhanced. 相似文献

Juvenile delinquency and high risk behaviors have been linked to disturbances in attachment. The present study examined parent
and peer attachment in 67 African American males and 97 Latinos (ages 12–17, M = 14.7 ± 1.3) attending an alternative school.
The Inventory of Parent and Peer Attachment was used to identify 3 attachment style groups: “Isolated,” “Disconnected,” and
“Connected.” Controlling for age, attachment group membership predicted differences in delinquent behaviors, as did ethnicity.
Further, on the Youth Self-Report of the Child Behavior Checklist, attachment group membership predicted differences in both
the Internalizing and Externalizing Scales. Implications for interventions with each identified attachment group are discussed. 相似文献
