Upper cervical trauma in motor vehicle collisions 总被引:1,自引:0,他引:1
Motor vehicle collisions can cause a variety of injuries in pedestrians and vehicle occupants. Fatal and nonfatal trauma to the upper cervical spine, that is, atlanto-occipital junction, atlas and axis, can be part of this spectrum. Certain distinctive injuries (for example, "hangman's fracture") which occur result from the unique anatomic structure of this area and the various disruptive forces such as extension, distraction (tension), compression (axial loading), shear, and inertia generated during collision. Correlation of autopsy findings or radiological information of these cervical injuries or both with scene investigation can be informative not only in the determination of morbidity and mortality, but also in the assessment of injury mechanisms and improvements in occupant protection. 相似文献

This article provides a brief history of tax and expenditure limitation initiatives in Oregon, along with a narrative of contemporary events. Largely as a consequence of the initiative's increased role in the formulation of Oregon's fiscal policy, state and local taxes paid by Oregon households declined from 7.4 percent of income in 1989 to 6.8 percent in 2003; state revenue, which is heavily dependent upon personal income taxes, has become increasingly income elastic; and state and local governments now rely on user fees to an almost unprecedented degree. 相似文献

This paper compares the macro- and micro- analyses of techno-economic change. Arguing for perspectives which are sensitive to the local flexibility of innovation but which can also provide suggestions for policy and intervention, it describes and reviews the two major contributions: work on Techno-Economic Networks, and on Techno-Economic Paradigms. It is argued that the former has greater depth of analytical sensitivity, whilst the latter is more policy-relevant. Whilst there are approaches, such as Constructive Technology Assessment, which attempt to combine the two perspectives, these are seen as failing to retain sensitivity to the power differentials between key actors such as firms, experts, governing agencies or citizens' groups. The paper concludes by advocating attention to the ‘meso-level techno-economic’—the networks of institutions and actors at work in: geographically bounded systems of innovation; scientific and technological disciplines; firms, their strategies and linkages; and the nexus between production and consumption. 相似文献

Seven neuropsychology journals that publish on topics relevant to clinical neuropsychology were examined for their experimental rigor according to the standards of the American Academy of Neurology (AAN) in their Clinical Practice Guidelines. By using a keyword approach on topics relevant to forensic neuropsychology, all articles that reported empirical findings from 2003 through 2008 were identified. Each study was rated by AAN classification criteria that ranged from a level I classification (prospective, most rigorous, and independent) to level IV (least rigorous). The typical forensic neuropsychological study averaged a class III ranking. Few studies were based on large sample sizes or utilized a reported masking or blind technique with regards to subject selection and how diagnostic criteria were met and/or data analyzed. While the authors for the average study reported a university affiliation, few reported explicit Institutional Review Board statements. Considerable variability across these seven journals with regards to conflict of interest (COI) disclosure policies was observed and only a few studies reported explicit statements about funding or COI issues. These observations suggest that neuropsychological research on forensic topics currently has many limitations and that future research needs to address these issues. 相似文献
