Vertebral artery removing constitutes a significant forensic pathology challenge. Dissection techniques during head-neck autopsy are based on anterior approach, a difficult method, which is unable to assess the transverse part of the artery. This work presents an original and simple method for dissecting vertebral arteries by a posterior approach, opening the vertebroarterial canal through the spinal canal without any special equipment. Once the spinal cord is removed, the transversarium foramens are opened by an internal cut at the pedicle and an external cut at the transverse process. This enables us to visualize vertebral arteries in its entirety. The method improves both the examination of the upper extracranial segment of the vertebral artery and the neuropathological study when arterial injury is suspected. Applying this method routinely is both feasible and useful in suspected cases of vertebral artery trauma and could contribute to assess more precisely the actual incidence of this injury.  相似文献

Traumatic vertebral artery dissection is not often seen by forensic pathologists, and cases investigated are scarce in the forensic literature. We present the case of a 40-year-old woman cyclist who was struck by a car while wearing a helmet, and was neurologically near normal immediately thereafter at Emergency. She presented 48 h later with acute right hemiparesis, decreasing level of consciousness, and unsteadiness. CT revealed massive cerebellar infarction. CT angiography was normal. The patient died in coma 7 days after injury and autopsy revealed bilateral edematous cerebellar infarction and bilateral vertebral artery dissection. Rotational neck injury and mural tear in the wall of the Atlantic parts of both vertebral arteries is suggested as the possible mechanism of the arterial injury. Head and neck injuries are reported as a precipitating cause of vertebral artery injury. The possible influence of trauma may be further underestimated if longer intervals between vessel dissection and ischemia occur. The current case illustrates that "talk-and-die" syndrome may be due to occult vertebral artery dissection, possibly bilateral. In forensic cases of delayed death after mild trauma to the head and neck, the vertebral arteries should be examined for the cause of death.  相似文献

In recent years a growing interest in gender diversity has arisen in the business context, and a significant number of research studies have analysed its effect on corporate performance. Nonetheless, these studies have not led to conclusive results, perhaps owing to the complexity of the relationship. The present work focuses on analysing two possible justifications of the contradictory effects of gender diversity on company performance: the business context and the optimum size of the female presence in decision-making bodies. The results obtained show that when working conditions and academic background are similar, women achieve better performance in sectors traditionally dominated by men. Moreover, to take the best advantage of gender diversity it is recommended that boards of directors should be balanced or have a slightly higher female presence.  相似文献

Indigenous movements have increasingly turned to the global arena to achieve their political goals at the national level. Using the norm diffusion model, the present article analyzes the relationship between the international indigenous rights regime (IRR) and the conceptualizations of indigenous territory used by four Mapuche organizations in Chile over the last 10 years. We find that the organizations draw on the IRR to frame their demand for autonomous territories based on historical Mapuche practices. We identify two conceptualizations: (1) a larger territory with political but not economic autonomy and (2) a smaller natural-cultural space characterized by a distinctive economic logic.  相似文献

Acts of violence recounted by 161 female victims of Intimate Partner Violence (IPV) attended at a psychological care service in Spain are presented. The relationship between acts of violence and feelings of danger, childhood abuse, and dyadic adjustment are analyzed. Reported acts of IPV were obtained through a Semi-structured Interview on Domestic Violence; and marital satisfaction was assessed with the Dyadic Adjustment Scale. The results showed women who have felt their lives were in danger are more likely to have been victimized. In addition, women who were both abused by their partner and sexually abuse as children are the ones that perceive more situations of danger in their adult couple relationship. The importance of studying perceived danger and the diversity of IPV experiences are discussed to aid prevention and intervention strategies.  相似文献

It has been more than 3 years since the collapse of the investment bank Lehman Brothers and the beginning of the Troubled Asset Relief Program. Most recently, the sovereign debt crisis in Europe has led to the bailout of the governments of Ireland, Portugal and Greece. A main reason behind these bailouts is to support European banks loaded with government bonds on their balance sheet. In this article we analyze the detrimental consequences of the public bailout in 2008 and argue that a free market alternative existed. The alternative of a private bailout outlined in this article, consisting of the conversion of liabilities into equity and a private capital increase, largely avoids the problems of a public bailout. Similarly, a public bailout of governments of the Eurozone to sustain banks may be detrimental.  相似文献

During the global financial crisis, criticism of the politicization and lack of professionalization of the savings banks has taken a central position in the political debate. The aim of this article is to analyze if the political presence of governing bodies in Spanish savings banks has been reflected in their various risk-taking behaviors before and during the financial crisis. We will also analyze whether the influence of the chairman’s banking experience matters. The results do not provide evidence that the composition of the boards of savings bank, or even their politicization, have played a role. However we show that savings banks run by a chairman with previous banking experience are likely to be significantly more solvent and less volatile.  相似文献

Objectives

The development and application of methods to assess consistency in sentencing before and after the 2011 England and Wales assault guideline came into force.

Methods

We use the Crown Court Sentencing Survey to compare the goodness of fit of two regression analyses of sentence length on a set of legal factors before and after the assault guideline came into force. We then monitor the dispersion of residuals from these regressions models across time. Finally, we compare the variance in sentence length of equivalent types of offences using exact matching.

Results

We find that legal factors can explain a greater portion of variability in sentencing after the guideline was implemented. Furthermore, we detect that the unexplained variability in sentencing decreases steadily during 2011, while results from exact matching point to a statistically significant average reduction in the variance of sentence length amongst same types of offences.

Conclusions

We demonstrate the relevance of two new methods that can be used to produce more robust assessments regarding the evolution of consistency in sentencing, even in situations when only observational non-hierarchical data is available. The application of these methods showed an improvement in consistency during 2011 in England and Wales, although this positive effect cannot be conclusively ascribed to the implementation of the new assault guideline.  相似文献
