With increasing interest in employing iris biometrics as a forensic tool for identification by investigation authorities, there is a need for a thorough examination and understanding of postmortem decomposition processes that take place within the human eyeball, especially the iris. This can prove useful for fast and accurate matching of antemortem with postmortem data acquired at crime scenes or mass casualties, as well as for ensuring correct dispatching of bodies from the incident scene to a mortuary or funeral homes. Following these needs of forensic community, this paper offers an analysis of the coarse effects of eyeball decay done from a perspective of automatic iris recognition. We analyze postmortem iris images acquired for a subject with a very long postmortem observation time horizon (34 days), in both visible light and near-infrared light (860 nm), as the latter wavelength is used in commercial iris recognition systems. Conclusions and suggestions are provided that may aid forensic examiners in successfully utilizing iris patterns in postmortem identification of deceased subjects. Initial guidelines regarding the imaging process, types of illumination, and resolution are also given, together with expectations with respect to the iris features decomposition rates. Visible iris features possible for human, expert-based matching persists even up to 407 h postmortem, and near-infrared illumination is suggested for better mitigation of corneal opacity while imaging cadaver eyes (Post-mortem iris decomposition and its dynamics in morgue conditions. ArXiv pre-print, 2019). 相似文献

AbstractThis article argues that when actors engage in controversial new security practices, it is misconceived to view secrecy as an opposed, counterproductive alternative to the pursuit of legitimation. Rather, we propose, deployment of “quasi-secrecy”—a combination of official secrecy with leaks, selective disclosure, and de facto public awareness—can be an effective strategy for achieving normalization and legitimation while containing the risks entailed by disclosure. We support this claim via a detailed case study of US targeted killing. First, we establish the existence of an American norm against targeted killing during the period 1976–2001. We then detail the process by which an innovation in practice was secretly approved, implemented, became known, and was gradually, partially officially acknowledged. We argue that even if quasi-secrecy was not in this instance a coherently-conceived and deliberately pursued strategy from start to finish, the case provides proof of concept for its potential to be deployed as such. 相似文献
The article concerns the actual impact of courts controlling the activity of public administration on the direction of its activities and the content of issued decisions. In particular, it concerns sovereign individual decisions that affect the sphere of civil rights and freedoms. The aim of the article is to seek an answer to the question of whether independent judges actually participate in the process of management in the public sphere, which is characterised by elements of politics and (regardless of the answer to this question) whether such participation is allowed or (even) necessary in modern rule of law states. The main argument is that regardless of whether the courts controlling the administration have reformatory or exclusive cassation powers, they influence the decision-making process in the public sphere. At the same time, such influence not only does not violate the fundamental values of the rule of law, but is even sometimes necessary. This does not mean that courts should interfere in the management processes in the public sphere in every case.
This article examines the contingent nature of financial industry lobbying power in the context of the policy formation stage of six European Commission regulatory proposals. I argue that lobbying success is a function of how well finance is able to speak with a unified voice. Building on existing studies, I examine industry unity as explicit preference alignment between actors but also in terms of actors abstaining from stating preferences. Staying silent on an issue sends signals to policymakers about issue saliency and industry support. Using a novel dataset derived from document coding and interviews, I examine the impact of industry unity on lobbying success in shaping six financial regulatory proposals in the context of the European Union. My findings show that lobbying success is partially contingent on the extent to which finance is united behind a common position. Critically, however, lobbying success is also related to the nature of that position, whether supporting the proposal or whether in favor of strengthening or weakening regulatory stringency. 相似文献
ABSTRACTThis Special Issue asks: what is the current place of militarism in relation to security where Africa is concerned? It aims to contribute to emerging debates interested in critical inquiry of the relation between militarism and security, and to explore its diverse articulations in African settings. We advance an international political sociological (IPS) approach to militarism in order to explore militarised security politics as a field of contested practices and logics. We discuss why this approach enables us to uncover the interconnected historical patterns and power relations in which practices and logics of security and militarism become linked and grounded in simultaneously local and transnational African settings. 相似文献
