Measuring the effect of ballot access restrictions on electoral competition is complicated because the stringency of ballot access regulations cannot be treated as being exogenous to candidates’ entry decisions. This paper exploits the 1968 U.S. Supreme Court decision to strike down Ohio’s ballot access law as a natural experiment to overcome the endogeneity problem. The evidence from difference-in-difference estimations suggests that the court’s decision and the accompanying sharp decrease in Ohio’s petition requirements resulted in major parties facing a significant increase in competition from third party and independent candidates.  相似文献

Legislative competence norms are paradigmatic elements of European constitutional law and the supranational, post‐federal era. The article aims to address legislative competence norms from the viewpoint of methodology by considering significant features of reasoning on European legislative competence norms. The discussion will be based on understanding legislative competences as ‘meta‐legislation’. That concept encompasses a substantive rather than formalistic, and a politically informed rather than strictly positivist account of legislative competences and their methodology. Against that background, the interpretation of competence norms is assessed. Subsequently, the process of interpretation is discussed according to judicial practice, constitutional theory and general legal methodology. A consideration of the significance of the—usually vast—wording of competence norms completes that discussion. Finally, consequences about the political inclusiveness of interpreting competence norms and the issue of ‘clarity’ are drawn. A conclusion summarises the results.  相似文献

In this article, we describe a method we have used successfully in both academic and professional settings to rapidly introduce novice negotiators to the principles and practice of interest‐based negotiation: “the walk in the woods.” The walk incorporates much of the principles of interest‐based negotiation: fostering self‐awareness, cultivating curiosity, and understanding the importance of world view. The walk's effectiveness is illustrated in this article using the case of the merger of two large, complex health‐care organizations.  相似文献

Kratom is an herbal product commonly used for its effects which are similar to opioids and stimulants. Few studies demonstrate the dangers and lethality of Kratom, and most fatalities from Kratom involve other abused substances. In the current case report, a 33‐year‐old white man with a known history of opioid abuse and mental illnesses was found unresponsive in his basement with no obvious signs of trauma. After resuscitative efforts, he was pronounced dead and taken for autopsy evaluation. Blood from the inferior vena cava was analyzed for common abused substances. The laboratory toxicology work‐up revealed positive findings of caffeine, cotinine, and naloxone with low levels of Δ‐9 tetrahydrocannabinol. However, a marked level of mitragynine at 1.9 mg/L was observed, the highest reported to date. Given the facts and evidence, the medical examiner certified the cause of death as “mitragynine toxicity” and the manner of death was classified as an “accident.”  相似文献

The transition from 2D imaging to 3D scanning in the discipline of firearms and toolmark analysis is likely to provide examiners an unprecedented view of microscopic surface topography. The digital examination of measured 3D surface topographies has been referred to as virtual microscopy (VM). The approach offers several potential advantages over traditional comparison microscopy. Like any new analytic method, VM must be validated prior to its use in a crime laboratory. This paper describes one of the first validation studies of virtual microscopy. Fifty‐six participants at fifteen laboratories used virtual microscopic tools to complete two proficiency‐style tests for cartridge case identification. All participating trained examiners correctly reported 100% of the identifications (known matches) while reporting no false positives. The VM tools also allowed examiners to annotate compared surfaces. These annotations provide insight into the types of marked utilized in comparative analysis. Overall, the results of the study demonstrate that trained examiners can successfully use virtual microscopy to conduct firearms toolmark examination and support the use of the technology in the crime laboratory.  相似文献

This article identifies key features of the sociotechnical contexts of computer law and security at the times of this journal's establishment in 1985, and of its 200th Issue in 2018. The infrastructural elements of devices, communications, data and actuator technologies are considered first. Social actors as individuals, and in groups, communities, societies and polities, together with organisations and economies, are then interleaved with those technical elements. This provides a basis for appreciation of the very different challenges that confront us now in comparison with the early years of post-industrialism.  相似文献

Many studies reveal strong interrater agreement for Hare's Psychopathy Checklist-Revised (PCL-R) when used by trained raters in research contexts. However, no systematic research has examined agreement between PCL-R scores from independent clinicians who are retained by opposing sides in adversarial legal proceedings. We reviewed all 43 sexual-offender civil-commitment trials in one state and identified 23 cases in which opposing evaluators reported PCL-R total scores for the same individual. Differences between scores from opposing evaluators were usually in a direction that supported the party who retained their services. These score differences were greater in size than would be expected based on the instrument's standard error of measurement or the rater agreement values reported in previous PCL-R research. The intraclass correlation for absolute agreement for the PCL-R Total score from a single rater (ICC 1,A = .39) was well below levels of agreement observed for the PCL-R in research contexts, and below published test-retest values for the PCL-R. Results raise concerns about the potential for a forensic evaluator's "partisan allegiance" to influence PCL-R scores in adversarial proceedings.  相似文献

Medical examiners and coroners commonly determine cause and manner of death without an autopsy examination. Some death certificates generated in this way may not state the correct cause and manner of death. From the case files of the Department of Forensic Medicine in Sydney, Australia, the authors retrospectively reviewed investigative information of all cases in a 6-month period that were initially considered natural deaths (429). The authors, blinded to autopsy results, accepted 261 cases as appropriate for certification without autopsy and assigned a cause of death to each. Per standard local practice, all cases had been autopsied. The actual causes of death as determined by autopsy were then revealed and compared with the presumed causes of death. Most presumed and actual causes of death were cardiovascular (94% and 80%, respectively). The majority of presumed causes of death were listed as ASCVD as the cases lacked features of a more specific cardiovascular process. A large majority of cases had a presumed cause of death of ischemic heart disease based on individual case details. The actual causes of death demonstrated a large breadth of cardiovascular and noncardiovascular disease processes, even though ischemic heart disease accounted for 62% of deaths. The presumed cause of death was completely wrong in 28% of cases. A nonnatural manner of death was present in 3% of cases. This study demonstrates that experienced forensic pathologists may generate erroneous death certificates for cases that are not autopsied.  相似文献

Routines, the habitual and predictable behavior patterns of an organization, play central roles in both maintaining organizational performance and in adapting such performance to changing conditions. Deadlines interact with routines in important ways in influencing the course of organizational adaptation. This paper examines the role of routines and deadlines in influencing change in a regulatory program. It describes the adaptation of routines in the Environmental Protection Agency's (EPA) water pollution and pesticide programs in response to pressures and deadlines imposed by Congress, the courts, and the White House. The programs analyzed offer contrasting glimpses of the effects of routines on organizational change. Routines may be collective and shared by the members of an organization or unique to the specific groups or subgroups within it. When the organization primarily has widely-shared routines, few options will be perceived; consequently, collective routines tend to blunt the impact of pressures for change. On the other hand, routines that become fragmented, diverse, and individual in the face of repeated external pressures may facilitate change.  相似文献
