Primary breast lymphoma is a rare form of extranodal lymphoma. B cells constitute the most common type involving the breast. T cells represents only 3%. Even though lymphomas have a high predilection to metastasize to the heart, there are no specific clinical or radiological findings, and most of the cases are diagnosed at autopsy. We discuss the case of a 49-year-old woman with primary breast lymphoma who presented with sudden death. Autopsy revealed a primary T-cell lymphoma of the breast with tumoral infiltration of the atrioventricular node and transmural myocardial permeation with focal necrosis.  相似文献

The quality of forensic mental health assessment has been a growing concern in various countries on both sides of the Atlantic, but the legal systems are not always comparable and some aspects of forensic assessment are specific to a given country. This paper describes the legal context of forensic psychological assessment in France (i.e. pre-trial investigation phase entrusted to a judge, with mental health assessment performed by preselected professionals called “experts” in French), its advantages and its pitfalls. Forensic psychiatric or psychological assessment is often an essential and decisive element in criminal cases, but since a judiciary scandal which was made public in 2005 (the Outreau case) there has been increasing criticism from the public and the legal profession regarding the reliability of clinical conclusions. Several academic studies and a parliamentary report have highlighted various faulty aspects in both the judiciary process and the mental health assessments. The heterogeneity of expert practices in France appears to be mainly related to a lack of consensus on several core notions such as mental health diagnosis or assessment methods, poor working conditions, lack of specialized training, and insufficient familiarity with the Code of Ethics. In this article we describe and analyze the French practice of forensic psychologists and psychiatrists in criminal cases and propose steps that could be taken to improve its quality, such as setting up specialized training courses, enforcing the Code of Ethics for psychologists, and calling for consensus on diagnostic and assessment methods.  相似文献

This study empirically investigates the impact of core labour standards on income inequality for a range of 90 countries from 1990–2000. A synthetic index of labour standards is computed by means of a Multiple Correspondence Analysis and no significant correlation is found with the Gini index. One of the reasons pointed out is that the effective implementation of core labour standards depends on the quality of the country's political and legal systems. Using instrumental variables in a TSLS model, we found an inverse ‘U’ shaped curve between the new endogenous index of core labour standards and income inequality.  相似文献

In the 1990s both Chile and Argentina embarked on efforts to tackle tax evasion. The strategies they pursued differed substantively: Argentina followed a coercive approach that created an elite audit team endowed with special legal powers, while Chile undertook a less spectacular service-oriented approach that improved the fiscal pact between state and society and enacted tax administration reform. Chile succeeded in permanently lowering tax evasion levels, while Argentina's success was short-lived and evasion levels soon returned to previous heights. Besides important differences in the institutional strength of these countries, the contrasting outcomes can be attributed in no small measure to the different strategies adopted. Their experience can provide some useful lessons in the elusive battle against tax evasion in Latin America.  相似文献

Studies increasingly highlight the limits of state building conducted ‘from the top-down’. Building on the literature and using a Rosenauian concept in a novel way, this article posits that international interventions create a ‘bifurcation of the two worlds’. Departing from a study of Kosovo and Timor-Leste, the article posits that the massive arrival of staff involved in international governance will create a social gap between the international and the local ‘worlds’, which will in turn become a target of narratives of resistance by local actors. This bifurcation is exemplified by the ‘white car syndrome’, a concept representing the horde of white UN vehicles accompanying major interventions and developed in this contribution. Thus, the article attempts to shed new light on the legitimacy crises that Kosovo and Timor-Leste experienced at the beginning of the current century, while demonstrating and increasing the linkages between development studies and peace studies.  相似文献

We studied sexually dimorphic differences in the ilium using geometric morphometric analysis of 10 osteometric landmarks recorded by multislice computed tomography, based on three‐dimensional reconstructions of 188 children (95 boys, 93 girls) of mixed origins living in the area of Toulouse, southern France, and ranging in age from 1 to 18 years. We used geometric morphometrics methodology first to test sexual dimorphism in size (centroid size) and shape (Procrustes residuals) and second to examine patterns of shape change with age (development) and size change with age (growth). On the basis of statistical significance testing, the ilium shape became sexually dimorphic at 11 years of age, although visible shape differences were observed as early as 1 year of age. There was no statistically significant difference in size between sexes. Trajectories of shape (development) and size (growth) differed throughout ontogeny and between sexes.  相似文献

Literature defining ‘police legitimacy’ lacks qualitative research on those populations most often targeted by law enforcement agencies, including people of color in urban areas. This same literature defines police legitimacy as something unquestionable and automatic. Exploration of this concept is limited to strategies to increase public ‘trust’ in police, and public compliance to their authority. We address these limitations in the available scholarship through an analysis of interviews with a diverse sample of Oakland (CA) residents on their experiences with the Oakland Police Department (OPD). Their narratives are presented in the historical context of controversy, budget problems, federal investigations, and racialized violence that help to define the relationship between OPD and Oakland communities. Those interviewed, universally observed OPD’s failure to address the most common crime problems in the city, while others, particularly people of color, found them to be a personal or public threat to safety. Their narratives fly in the face of the manifest functions of municipal police forces, are fully supported by the contemporary empirical history of the OPD, and suggest the illegitimate authority – including the monopoly on the use of force – of organizations like OPD in a democratic society.  相似文献

Abstract

This article addresses two questions about spatial barriers to welfare‐to‐work transition in the United States. First, what residential and transportation adjustments do welfare recipients tend to make as they try to become economically self‐sufficient? Second, do these adjustments actually increase the probability that they will become employed?

Analysis of 1997–2000 panel data on housing location and automobile ownership for Milwaukee welfare recipients reveals two tendencies: (1) to relocate to neighborhoods with less poverty and more racial integration and (2) to obtain a car. Results from binary logit models indicate that residential relocation and car ownership both increase the likelihood that welfare recipients will become employed. These findings suggest that policies should aim to facilitate residential mobility for low‐income families and improve their neighborhoods, rather than simply move them closer to job opportunities. The findings also suggest a critical role for transportation policy in reducing unemployment.  相似文献

Short tandem repeat (STR) analysis is a valuable tool in identifying the source of biological stains, particularly from the investigation of sexual assault crimes. Difficulties in analysis arise primarily in the interpretation of mixed genotypes when cell separation of the sexual assailant's sperm from the victim's cells is incomplete. The forensic community continues to seek improvements in cell separation methods from mixtures for DNA typing. The feasibility of applying laser microdissection (LMD) technology to precisely separate sexual assault cell mixtures by visual inspection coupled with laser dissection was assessed through three experiments. First, various histological stains were evaluated for use with LMD and DNA analysis. Second, different DNA isolation methods were evaluated on LMD-collected cells. Finally, STR analysis was performed on LMD-separated sperm cells from mixtures of semen and female buccal epithelial cells. The results indicated (a) hematoxylin/eosin staining performed best in its ability to differentiate sperm and epithelial cells while exhibiting the least negative effect on further downstream analysis; (b) both QIAamp and Lyse-N-Go methods were useful for recovery of DNA from LMD-collected sperm cells; and (c) LMD separation provided clear STR profiles of the male donor with the absence of any additional alleles from the female donor. This report describes an efficient, low-manipulation LMD method for the efficient separation of spermatozoa from two-donor sperm/epithelial cell mixtures.  相似文献
