"Brain death," the determination of human death by showing the irreversible loss of all clinical functions of the brain, has become a worldwide practice. A biophilosophical account of brain death requires four sequential tasks: (1) agreeing on the paradigm of death, a set of preconditions that frame the discussion; (2) determining the definition of death by making explicit the consensual concept of death; (3) determining the criterion of death that proves the definition has been fulfilled by being both necessary and sufficient for death; and (4) determining the tests of death for physicians to employ at the patient's bedside to demonstrate that the criterion of death has been fulfilled. The best definition of death is "the cessation of functioning of the organism as a whole." The whole-brain criterion is the only criterion that is both necessary and sufficient for death. Brain death tests are used only in the unusual case in which a patient's ventilation is being supported. Brain death critics have identified weaknesses in its formulation. But despite its shortcomings, the whole-brain death formulation comprises a concept and public policy that make intuitive and practical sense and that has been well accepted by many societies.  相似文献

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

Many illicit drugs involve the use of paraphernalia, and the presence of paraphernalia found at the scene of death may suggest that the death is drug‐related. Few sources of objective data are available regarding the prevalence of drug paraphernalia found at the scene of drug‐related deaths or the likelihood of a death with drug paraphernalia found at the scene to be drug‐related. This study reviews the deaths which were investigated by the Bexar County Medical Examiner's Office in an attempt to provide objective data. Over 4000 deaths with scene investigations were reviewed, and the presence of paraphernalia was found to be strongly associated with the death being drug‐related, heroin‐related, or cocaine‐related with the relative risk for each being 5.0, 15.4, and 6.6, respectively. This confirms that the presence of drug paraphernalia at the scene of death strongly suggests the death to be drug‐related and in particular heroin‐related.  相似文献

Abstract: In this article, the authors discuss the problem of forensic authentication of digital audio recordings. Although forensic audio has been addressed in several articles, the existing approaches are focused on analog magnetic recordings, which are less prevalent because of the large amount of digital recorders available on the market (optical, solid state, hard disks, etc.). An approach based on digital signal processing that consists of spread spectrum techniques for speech watermarking is presented. This approach presents the advantage that the authentication is based on the signal itself rather than the recording format. Thus, it is valid for usual recording devices in police‐controlled telephone intercepts. In addition, our proposal allows for the introduction of relevant information such as the recording date and time and all the relevant data (this is not always possible with classical systems). Our experimental results reveal that the speech watermarking procedure does not interfere in a significant way with the posterior forensic speaker identification.  相似文献

This article examines change and divergence in the politics of partnership-based governance of two weak neo-corporatist countries, Italy and Spain. Evolution in the forms and processes of concertation is driven by a logic of interaction guiding actors' behaviour which is different from that theorised for strongly neo-corporatist countries. As the framework governing the industrial relations system is characterised by conflict and poor coordination capacities, change will take the form of a top-down search for accommodation of this conflict through political exchange in contexts where neo-corporatist institutions provide weak constraints on actors' behaviour. This has been possible in the last decade because political participation, though weakly institutionalised, remained for trade unions a positive course of action used instrumentally in order to achieve policy and organisational benefits. Hence, the divergent evolutions of the two countries are to be traced back to factors affecting the strategic decision of political participation of trade unions, in particular inter-union ideological and political divisions and the dynamics of the relationship between grass roots and leadership.  相似文献

We analyse how forced displacements caused by violent conflict are related to the wages of workers in Colombia. Using data from the Quality of Life Survey (2011–2014), we analyse the differences in wages between those forced by violence to move to other regions, and those who moved for other reasons. We apply Propensity Score Matching techniques to compare workers from the two groups, finding that forced displacement is related to decreases of between 10 and 29 per cent in the wages of males, and between 18 and 37 per cent in the wages of females, relative to their counterparts. Thus, forced displacements are related to poorer labour market outcomes in terms of wages.  相似文献
