The stability of ethanol in antemortem blood stored under various conditions has been widely studied. Antemortem blood samples stored at refrigerated temperature, at room temperature, and at elevated temperatures tend to decrease in ethanol concentration with storage. It appears that the stability of ethanol in blood exposed to temperatures greater than 38°C has not been evaluated. The case presented here involves comparison of breath test results with subsequent analysis of blood drawn at the time of breath testing. However, the blood tubes were in a refrigerator fire followed by refrigerated storage for 5 months prior to analysis by headspace gas chromatography. The subject’s breath was tested twice using an Intoxilyzer 8000. The subject’s blood was tested in duplicate using an Agilent headspace gas chromatograph. The measured breath ethanol concentration was 0.103 g/210 L and 0.092 g/210 L. The measured blood ethanol concentration was 0.0932 g/dL for both samples analyzed. Although the mean blood test result was slightly lower than the mean breath test result, the mean breath test result was within the estimated uncertainty of the mean blood test result. Even under the extreme conditions of the blood kit being in a refrigerator fire, the measured blood ethanol content agreed well with the paired breath ethanol test. 相似文献

Understanding human aggression: New insights from neuroscience 总被引:1,自引:0,他引:1
The present paper reviews and summarizes the basic findings concerning the nature of the neurobiological and behavioral characteristics of aggression and rage. For heuristic purposes, the types of aggression will be reduced to two categories — defensive rage (affective defense) and predatory attack. This approach helps explain both the behavioral properties of aggression as well as the underlying neural substrates and mechanisms of aggression both in animals and humans. Defensive rage behavior is activated by a threatening stimulus that is real or perceived and is associated with marked sympathetic output. This yields impulsivity with minimal cortical involvement. Predatory attack behavior in both animals and humans is generally planned, taking minutes, hours, days, weeks, months, or even years (with respect to humans) for it to occur and is directed upon a specific individual target; it reflects few outward sympathetic signs and is believed to require cortical involvement for its expression. Predatory attack requires activation of the lateral hypothalamus, while defensive rage requires activation of the medial hypothalamus and midbrain periaqueductal gray (PAG). Both forms of aggressive behavior are controlled by components of the limbic system, a region of the forebrain that is influenced by sensory inputs from the cerebral cortex and monoaminergic inputs from the brainstem reticular formation. Control of aggressive tendencies is partly modifiable through conditioning and related learning principles generated through the cerebral cortex. 相似文献

To maintain public safety and improve system response, a strong need exists for understanding the contexts of and police response to weapon-related incidents as well as socio-economic variables of individuals involved. This paper was focused on exploring these contexts and routine police activities by creating and analyzing a weapon-related database at the local level. The findings, although limited due to the explorative nature of the study and the quality of case files, shed some interesting light on the effects of environmental and operational variables on gun incidents and expose certain issues that need to be resolved before further and more accurate understanding of gun crimes at the local level can be achieved. 相似文献

We present a review of theoretical and methodological advances in the social scientific literature on environmental inequality/racism and argue for new directions in research efforts that pay more attention to (1) the historical forces driving environmental justice conflicts; (2) the complex role of stakeholders in these struggles; (3) the role of social inequality, particularly the trade-offs between environmental protection and social equity; and (4) the impact of social movement activity on the state of environmental protection. Drawing on a case study of an environmental justice conflict in the United States, we find that environmental inequality impacts many actors with often contradictory and cross-cutting allegiances. These struggles therefore become a moving drama—a process—rather than a cross-sectional outcome. We conclude with an analysis of environmental inequality on a global scale and argue that the role of transnational capital remains largely untheorized in the literature. We suggest new models for explaining environmental inequality's causes and consequences. 相似文献

Moving Policy Theory Forward: Connecting Multiple Stream and Advocacy Coalition Frameworks to Policy Cycle Models of Analysis 下载免费PDF全文
Michael Howlett Allan McConnell Anthony Perl 《Australian Journal of Public Administration》2017,76(1):65-79
The stages/policy cycle, multiple streams, and Advocacy Coalition Framework (ACF) approaches to understanding policy processes, all have analytical value although also attracting substantive criticism. An obvious direction for research is to determine whether the multiple streams framework and the ACF can be refined and applied to other dimensions of policy‐making set out in the policy cycle model. This article argues that extending and modifying Kingdon's framework beyond the agenda‐setting stage is best suited to this endeavour. Doing so makes it possible to bring these three approaches into alignment and enhances our understanding, although retaining the core insights of each. 相似文献

Allan Cochrane 《Local Government Studies》2016,42(6):907-915
In 2004, Local Government Studies published an article in which I reflected on the implications of new Labour’s modernisation agenda for the remaking of local government and the reshaping of the welfare state. Here I return to some of the issues raised in that paper in the different context of localism, austerity and dreams of urban entrepreneurialism. I argue that exploring the changing meanings of the local, as a contested political as well as geographical category, is a fundamental task for those of us seeking to understand the nature of contemporary local government; the wider processes of state restructuring which frame it; and the possibilities of local politics. 相似文献
