One possible solution to the problem of subjectivity in the interpretation of social phenomena is the application of models derived from formal grounded theory, since such models make explicit the writer's perspective and the assumptions he or she brings to the social situation. This article uses the Status Passage Theory of Glaser and Strauss (1971) to analyze systematically the way in which English Magistrates' Courts deal with defendants. It identifies various features in the courtroom and precourtroom processes and in the attitudes of the courtroom professionals that appear consistent with the view that the social degradation of offenders is an implicit, yet important, objective of these courts. Finally, comparisons are made between the lower criminal courts in England and the United States and tentative explanations offered as to why differences exist between social degradation aspects of the two systems.This article is an abridged and revised section of the author's LL.M. thesis. Many of the revisions are the result of helpful comments made by Tony Bottoms, Peter Moodie, and Barbara Harrel-Bond on the original thesis.  相似文献

Non‐atherosclerotic spontaneous coronary artery dissection (NA‐SCAD) is a rare cause of morbidity and mortality with a propensity for young, healthy, and often peripartum women. NA‐SCAD etiology is poorly understood, with possible hormonal and hereditary mechanisms. Current treatment strategies range from conservative management (often showing resolution on angiographic follow‐up) to invasive angiographic procedures. Rarely, NA‐SCAD has recurred in another coronary artery, ranging hours to years later. We report NA‐SCAD of the right coronary artery (RCA) in a 30‐year old, 3‐month postpartum female with an additional autopsy finding of remote myocardial infarction (MI) in the left anterior descending (LAD) coronary artery territory. The remote MI is consistent with prior NA‐SCAD of the LAD and, given the medical history, may have occurred in the peripartum period of the decedent first pregnancy 3 years earlier. As such, to the best of our knowledge, this may represent the first reported case of NA‐SCAD recurrence in a subsequent pregnancy.  相似文献

We propose a multilevel account of legislative Court curbing in order to assess existing explanations as to why such proposals come about. We argue that although Court curbing is commonly seen as the result of institutional conflict between Congress and the Supreme Court, it is best understood as a product of three interrelated factors: the individual motivations on the part of lawmakers, the partisan context in which they operate, and institutional disagreements between Court and legislature. We find evidence that micro‐level factors offer an important insight into Court curbing that institution‐focused explanations alone cannot.  相似文献

Media reports about fatal work accidents in zoos caused by zoo animals seem to appear in increasing numbers all around the world. In many cases the cause of such an accident can only be clarified by a detailed reconstruction of the event in combination with the autopsy results. This applies particularly in cases where no eyewitnesses were present. This report is about the case of a musk ox that killed its keeper, in which the fatal accident could be completely reconstructed.  相似文献

Cocaine is an illicit drug frequently encountered by forensic practitioners in driving under the influence of drugs (DUID) casework. Whole blood collected from a suspected drugged driver was found to contain 3.000 mg/L cocaine, 1.600 mg/L benzoylecgonine, and 0.260 mg/L methamphetamine. The high concentration of cocaine, while common in overdose death investigations, is unusual for an impaired driving case. Information from the officer revealed that the motorist swallowed cocaine during the traffic stop. Although a cocaine DUID charge could not be pursued, the blood methamphetamine concentration exceeded the State of Nevada “per se” limit for operating a motor vehicle. The motorist was successfully prosecuted for DUID based on his admission of using methamphetamine prior to driving and the blood methamphetamine result. This case highlights the importance of considering case history when interpreting laboratory results and the application of jurisdictional statutes as an approach to prosecuting suspected drug‐impaired drivers.  相似文献

Psychostimulant use is associated with increased stroke risk. To determine the proportion of psychostimulant users among fatal strokes in young adults (15–44 years), all cases were retrieved from the National Coronial Information System (1/1/2009–31/12/2016). A total of 279 cases were identified: hemorrhagic (259), ischemic (8), thrombotic (8), and mycotic (4). Fifty (17.9%) were identified as psychostimulant users. Psychostimulants in blood were detected in 37/45 where toxicology was available, predominantly methamphetamine (32/45). Hemorrhagic strokes in the psychostimulant group were more likely to be intraparenchymal (OR 2.33). Psychostimulant users were less likely to be obese (OR 0.31), but more likely to have a history of tobacco use (OR 2.64). No psychostimulant user had a previous stroke history, was gravid/postpartum, or diagnosed with cerebral vasculitis or endocarditis. The work illustrates the substantial role of psychostimulant use in fatal strokes among young adults. In cases of hemorrhagic stroke among young adults, psychostimulant use should be considered.  相似文献
