Disclosure of neurological disorders by neuropathological examination may be one important aim of forensic autopsies. There are insufficient data on human brain tissue preservation after prolonged postmortem periods. Here, we describe neuropathological findings in a brain of a 77-year-old woman that was fixed at autopsy 2 months after death. The body had been stored in a cooling chamber at 3 degrees C temperature. Gross inspection of the brain was satisfactorily possible. Histomorphology was excellently preserved. Many histochemical and immunohistochemical stains allowed satisfactory neuropathological evaluation of brain tissue and the diagnosis of Alzheimer's disease. Nevertheless, some immunohistochemical stainings repeatedly yielded negative or suboptimal results. We conclude that neuropathological examination of human brain tissue extracted from the skull and fixed after prolonged body storage in a cool environment is feasible for forensic diagnosis of neurological disorders even several months after death. However, in such cases the significance of negative immunohistochemical staining results must be interpreted with caution.  相似文献

The recent enforcement of the GDPR has put extra burdens to data controllers operating within the EU. Beyond other challenges, the exercise of the Right to be Forgotten by individuals who request erasure of their personal information has also become a thorny issue when applied to backups and archives. In this paper, we discuss the GDPR forgetting requirements in respect with their impact on the backup and archiving procedures stipulated by the modern security standards. We specifically examine the implications of erasure requests on current IT backup systems and we highlight a number of envisaged organizational, business and technical challenges pertained to the widely known backup standards, data retention policies, backup mediums, search services, and ERP systems.  相似文献

Abstract:  Authentic black-powder muzzle-loader weapons or replicas are used today primarily for re-enactments of historic battles. A lay actor playing the role of a Prussian infantryman sustained life-threatening gunshot injuries during a recent re-enactment of a historic battle of the Sixth Coalition. As only blank historic muzzle-loading weaponry was used, the origin of the missile causing the wounding was initially unclear. Further investigation revealed a ramrod that had been propelled out of the barrel of another gunner's smooth-bore gun as cause of injury. The ramrod was hurled on a trajectory of more than 20 m, breaking the victim's shouldered barrel and hitting the victim resulting in severe abdominal, thoracic, and upper limb injuries. The critical incidents while handling muzzle-loading weaponry leading to premature discharge are elucidated. Furthermore, this report demonstrates how actual diagnostics and subsequent surgical treatment enabled this infantryman to survive an injury to which his comrades-in-arms would have succumbed 200 years ago.  相似文献

Risk has become a ubiquitous tool for security governance. This paper analyzes the ongoing shift in airport/aviation security from rule-based to risk-based screening. Seeking to explore the effects of data based passenger risk assessment on privacy through the collection and processing of personal data, it is argued that risk is likely to enroll passengers into a partly voluntary, partly enforced membership in trusted traveler schemes in order to enhance the database, thus enabling a more precise assessment of risk levels. In a disciplinary spatial setting, the once distinct privacy dimensions of citizen-state and consumer-market become increasingly blurred, as law enforcement authorities seek to exploit data that was originally obtained for commercial purposes to improve risk calculations.  相似文献

The paper deals with vertical tax competition between self-interested governments in a dynamic environment. In a federation, competition between the federal and the state governments arises when tax sources are not separated but pooled. Since dynamic inefficiencies will be stressed, the focus is on fiscal stock externalities rather than on flow externalities. The paper shows that the Leviathans in a federation tax the fiscal common resource more extensively than the single Leviathan in a unitary state. Furthermore, the positive impact of political stability on public consumption of the fiscal common will be discussed.  相似文献
