Eine jüngst ergangene Entscheidung des OGH (6 Ob 204/11k wbl 2012, 291) bietet Anlass, über das Verh?ltnis der Ausfallshaftung (§ 70 GmbHG) zum Kaduzierungsverfahren (§ 66 GmbHG) nachzudenken. Die Rechtsfrage lautet: Bedarf die Geltendmachung der Ausfallshaftung der vorherigen Durchführung eines Kaduzierungsverfahrens?  相似文献

Situating events and traces in time is an essential problem in investigations. To date, among the typical questions issued in forensic science, time has generally been unexplored. The reason for this can be traced to the complexity of the overall problem, addressed by several scientists in very limited projects usually stimulated by a specific case. Considering that such issues are recurrent and transcending the treatment of each trace separately, the formalisation of a framework to address dating issues in criminal investigation is undeniably needed. Through an iterative process consisting of extracting recurrent aspects discovered from the study of problems encountered by practitioners and reported in the literature, common mechanisms were extracted and provide understanding of underlying factors encountered in forensic practise. Three complementary approaches are thus highlighted and described to formalise a preliminary framework that can be applied for the dating of traces, objects, persons and indirectly events.  相似文献

Little research has investigated the prevalence of mood disturbance among sex offenders despite the fact that psychological distress may bear some relationship to community reintegration, and ultimately, recidivism. All offenders on New Jersey’s sex offender Internet registry were mailed surveys about their experiences with, and perceptions of, notification and residence restriction statutes, the Beck Depression Inventory-II (BDI-II), and the Beck Hopelessness Scale (BHS). On average, respondents (N = 104) reported mild to moderate levels of depressive symptoms (M BDI = 17.1) and hopelessness (M BHS = 6.9). Additionally, offenders who reported being negatively affected by residence restrictions and notification statutes reported higher levels of both depression and hopelessness. Given evidence that sex offender specific legislation may de-stabilize offenders, this research highlights the importance of managing affective states in this population.  相似文献

Presidential candidates regularly use crime issues to help win electoral support. Contrary to conventional wisdom, crime control became an issue in the 2008 presidential campaign. Despite decreasing crime rates and public opinion focused only temporarily on illegal immigration, the three major presidential candidates (Obama, Clinton, & McCain) discussed many anticrime initiatives during the campaign. Unlike past research which has found presidential candidates use primarily symbolic rhetoric in their anticrime rhetoric, all three presidential candidates in the 2008 presidential election were found to have employed tangible statements. The article discusses the different findings, making recommendations for future research.  相似文献

The publication deals with topics concerning the interpretation of the Vigrahavyāvartanī in as much as they are relevant for the understanding of (early) Madhyamaka-philosophy in general. A major part of the article is dedicated to a critical assessment of a number of views which have been propagated recently in a paper by Sharma (In: Nagoya studies in Indian culture and Buddhism, Saṃbhāṣā, 2011). A primary goal of the present investigation consists in substantiating the claim that early Madhyamaka represents a metaphysical teaching which stands in sharp contrast not only to stances of common sense but also to tenets propagated in Buddhist dogmatics.  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
