How do MPs in nascent legislatures choose a political party? We argue that MPs self‐select into groups of like‐minded colleagues to achieve favored policy outputs. MPs identify colleagues with similar preferences based on observed behavior and informative signals such as socioeconomic status, cultural background, and previous political experience. We test this explanation in the first democratically elected German parliament, the Frankfurt Assembly of 1848, that developed a differentiated party system in the absence of electoral and career incentives. Our statistical analysis shows that MPs were significantly more likely to join parties that were similar to them with regard to ideology, age, regional provenance, confession, noble status, and previous parliamentary experience. Qualitative evidence suggests that major changes in the party system were driven by disputes over policy. Our findings are particularly important for countries with more turbulent paths towards parliamentarization than those witnessed by archetypical cases like Britain or the United States.  相似文献

Nitrites are commonly used in the chemical, pharmaceutical, and food industries. Recently, they have been identified in cases of voluntary intoxication. We report the case of a 13-year-old girl who was found lifeless on her bed next to a glass containing a white powder and a bottle containing a white powder with a moistened appearance. External examination and autopsy revealed a nonspecific asphyxia syndrome, which was confirmed by the pathological analysis. Analysis of the samples revealed metoclopramide in the peripheral blood at a concentration of 0.402 mg/L (LC–HRMS). An analysis of the gastric contents was carried out after sodium nitrite was detected in the powders found near the body (Raman spectrometry). Nitrites were found in the gastric fluid at a concentration of 30.9 mg/L. Death occurred secondary to anoxia, following ingestion of nitrites; suicide kits are available on the web and nitrites are relatively easy to source and inexpensive. Nitrites are delivered in powder form to be dissolved in liquid, which may then be consumed with metoclopramide (or an alternative anti-emetic drug) to maximize absorption and reduce emesis. The toxic effect of nitrites lies in their oxidizing power, causing the transformation of hemoglobin into methemoglobin, which, when it accumulates, induces tissue anoxia resulting in death. There has been an alarming increase in the number of cases linked to suicide using nitrites or a nitrite suicide kit. The fact that nitrites are readily available online underscores the importance of establishing effective preventive measures such as limiting the access and use of this chemical.  相似文献

Human fetal skeletal elements of different gestational ages were screened with multiple mesh sizes (6.4 mm [1/4 inch], 3.2 mm [1/8 inch], 2.0 mm, and 1.0 mm) to determine their recovery rates. All remains were previously macerated, and no significantly damaged elements were used. The 6.4 mm mesh allowed a large loss of elements (63.2% overall), including diagnostic elements, while no diagnostic elements were lost when the 1 mm mesh (0.2%) was used. When using the 3.2 mm mesh, 16.2% of the bones were lost, including some diagnostic elements (primarily tooth crowns), while 7.5% were lost using the 2.0 mm mesh. The authors recommend that the potential loss of information incurred when utilizing larger mesh sizes be taken into consideration when planning recovery methods where fetal remains may be encountered and that a minimum of 1.0 mm mesh be utilized in recovery contexts known to include fetal remains.  相似文献

Drug users often define themselves as functional users and depict others as dysfunctional (i.e. junkies). Previous research on the social identities of drug users has focused on the symbolic boundaries they create to distance themselves from stigmatized others. Investigators have yet to focus on how users account for their own boundary violations. Here, we examine the narratives of 30 former women methamphetamine (meth) users to determine how they make distinctions between functional and dysfunctional meth users (i.e. “meth heads”). The distinctions they make are based on users’ abilities to maintain control of their lives and to hide their use from outsiders. Those who saw themselves as functional but who engaged in behaviors inconsistent with this image accounted for these behaviors to maintain desired identities. We show the complexity of drug users’ identities and illustrate how anti-drug campaigns that provide grotesque caricatures of drug users may prolong drug using careers.  相似文献

A recent quantitative evaluation of mainstream criminological research found that there is a dearth of research on “Indigenous peoples in the criminal justice context” conducted in Australia, Canada, New Zealand, and the United States and published in elite criminology journals while these nations continue to incarcerate Indigenous peoples at markedly disproportionate rates. Although the silence prohibits public attention to this social issue, counter-colonial critics have mostly focused on criminologists who deliberately marginalize Indigenous peoples through use of inappropriate research methods. This study is a first attempt to quantify the use of “silencing research methods” in contemporary mainstream criminology. It involves a comprehensive review of research published in elite criminology journals over the past decade (2001–2010). The findings reveal that although mainstream criminologists generally prefer non-silencing research tools, they primarily employ silencing research methods when studying Indigenous peoples. Also, studies that focus on Native American peoples use silencing research tools more often than studies on other disproportionately incarcerated social groups, i.e., African and Hispanic Americans. The study concludes that by using “silencing research methods,” elite mainstream criminology has contributed to the marginalization of Indigenous peoples to varying degrees in all four countries over the past decade.  相似文献

Public inquiries are an important phenomenon in modern British society, often used to address controversial or difficult issues of major concern to policy makers, the media and the public. Although people often comment adversely on how costly inquiries are and how long they take, inquiry methods are rarely discussed, let alone critiqued or challenged. However, from a social sciences perspective, inquiry methods, processes and outputs are often at odds with accepted standards for research methods. This paper discusses this divergence and the implications for how we should regard the inquiry as a way of knowing, or learning.  相似文献

和谐社会的根基就是民主法治,而法治社会则必须保证司法公正。在构建社会主义和谐社会的进程中,依靠公正的司法来维护社会的公平与正义,通过司法裁决的方式来解决社会问题、经济问题乃至政治问题,应当成为整个社会的首选。因此,探究影响司法公正的原因,实现和维护司法公正,已经成为构建和谐社会的迫切要求与重要任务。  相似文献

目前,公安院校普遍实行计划性学年制教育,这种教学制度存在诸多弱点,根据公安教育的特点,公安院校实行计划性学分制是大势所趋。同时,要实行学分制,还必须在思想观念、教学、管理及师资队伍方面具备一些基本条件。  相似文献
