Healthy men, 20 to 60 years old, drank a moderate dose of ethanol in the morning after an overnight fast. They consumed either neat whisky in amounts corresponding to 0.34, 0.51, 0.68, 0.85, or 1.02 g of ethanol per kilogram of body weight or 0.80 g/kg ethanol solvent diluted with orange juice. The peak blood-ethanol concentration (BEC) increased with the dose administered, but the time required to reach the peak was not markedly influenced over the range of doses studied. At a dose of 0.68 g/kg, the peak BEC ranged from 52 to 136 mg/dL (N = 83), and slow absorption (a late-occurring peak) produced a lower peak BEC. The peak BEC was reached between 0 and 45 min for 77% of the subjects (N = 152) and between 0 and 75 min for 97% of them. The time of peaking in venous blood occurred, on average, 10 min later than in capillary (fingertip) blood although the peak BEC was not appreciably different; the mean venous BEC was 97.0 mg/dL (range, 76 to 112 mg/dL), and the mean capillary BEC was 99.6 mg/dL (range, 75 to 123 mg/dL). When subjects drank 0.80 g/kg ethanol diluted with orange juice over 30 min, the average BEC increment between the end of drinking and the peak was 33 mg/dL (range, 0 to 58 mg/dL). The rate of absorption of ethanol was 1.78 mg/dL/min (range, 0.52 to 4.8 mg/dL/min), and the peak BEC occurred within 60 min after the end of drinking in 92% of the trials. The largest BEC increment (mean, 21 mg/dL; range, 0 to 44 mg/dL) was seen during the first 15 min after the drinking period.  相似文献

When Hurricane Katrina made landfall on the Mississippi Gulf Coast in August 2005, it immediately overwhelmed the abilities of local and state emergency management officials to respond to the ensuing disaster. Although the U.S. Coast Guard and some military units were on scene shortly after the passage of the storm, there seemed to be interminable delays before the military forces began to arrive in numbers to both provide humanitarian relief and secure the affected areas. This article analyzes the response of the National Guard, active-duty military, and Coast Guard forces through the lens of coordination. We find evidence of the successful use of both traditional hierarchical and network-based coordination; we also find support for Donald Kettl's idea of "contingent coordination."  相似文献

Middle‐class families face a range of challenges, including uneven income growth, imposing child care costs, and affordability gaps for higher education. The ideal policies by which policy makers and public administrators can aid the middle class are far from obvious. Policy solutions are likely to mirror our government and population, meaning that they will be decentralized and varied. Achieving a “growing and thriving middle class” requires understanding the composition of the middle class across the country. Benchmarking and measuring the middle‐class condition at the state and substate levels is critical to crafting and adopting effective policy solutions. This Viewpoint essay highlights the Colorado context to demonstrate the measurement of the middle class and tracking of its lived experiences.  相似文献

The global infrastructure sector is thriving. But community opposition to major projects is also rising. Australian examples demonstrate the policy backflips, reputational pitfalls, and financial costs of project delays and cancellations. Failures to engage communities are surprising, given the widespread adoption of community engagement (CE) principles and the increasing professionalization of CE roles. If acceptance of the need for CE in infrastructure is more widespread than ever, why are we not seeing smoother project delivery, reduced protest, and cost savings? This paradox is the driving force behind the Next Generation Engagement project. This article offers a practitioners’ perspective to introduce the project and present key findings from its 12‐month pilot study aiming to establish a transdisciplinary, industry‐led research agenda for CE in Australia's infrastructure sector. The article contributes to our understanding of CE literature and research codesign. It maps out the top five priority themes for future research to support infrastructure selection, planning and delivery. The research agenda provides guidance for policy, and practice, offering consolidated, research‐based insights for policymakers and practitioners.  相似文献

Negative elite and news media attention to Latino‐relevant issues, particularly undocumented immigration, has dramatically increased in recent years, potentially stigmatizing attributes of Latinos such as immigration status and language use. Concomitantly, immigration policy changes were leading to widespread arrests and deportation of many Latinos. Herein, we ask two questions: First, to what extent do Latinos perceive and experience discrimination? Second, to what extent do immigration status, generational status, and language use moderate beliefs about discrimination? Using Pew National Survey of Latinos data, we find that Latino beliefs about the problem of discrimination is a decreasing function of “proximity” to the “canonical immigrant”—defined here as first‐generation immigrants who are Spanish‐language dominant. Further, we demonstrate that reported rates of victimization due to discrimination exhibit no clear pattern and are flat over time. We conclude by demonstrating that discrimination beliefs have significant implications for systemic trust, anxiety, and policy preferences.  相似文献

Transition teams are often used to help Prime Ministers and Premiers move into their new roles. At the municipal level, the use of transition teams is relatively new. As such, we know little about what these groups do in comparison to federal and provincial transition teams. In this article, we examine mayoral transition teams and find that the increased use of these groups is a reflection of the enhanced organizational complexity of Canadian local government. Additionally, local conditions and candidate experience often dictate the shape and function of transition teams. Overall, we argue that more resources should be devoted to the municipal transition process.  相似文献

This article is the fourth in a series introducing the reader to methods and theories relevant to advancing socio-legal research. They are written for the curious rather than the expert reader and provide illustrations of how the theories, methods, and frameworks have been employed and might be used in your work. This article explores the use of case biography methods for socio-legal studies. Drawing on ‘paths to justice’ studies, network analysis, and legal archaeology, we develop a case study of AC v.Berkshire West Primary Care Trust. We show how the judicial determination of the case suppressed a transgender rights narrative construction of the dispute in favour of one about health care law. Our case biography analysis explores how competing narratives can be traced not only through legal argument and literature, but also through the personnel involved, in ways that are obscured by formal records. Paying attention to biographical features leads to a richer understanding of cases, including the importance of pre- and post-judicial decision-making aspects.  相似文献
