Recent policies enacted regarding sex offenders include the formation of a publicly accessible sex offender registry, community notification, and residential restrictions. Often the motivation behind these policies is to get information out about sex offenders to community members so that these communities can effectively guard against any revictimization by the sex offenders among them. Theoretically, the premise for this type of legislation corresponds to relationships specified by routine activities theory. The theory states that if guardians can interrupt potential offenders as they are preying on suitable targets, these crimes-in-the-making will not occur. The present study assesses routine activities theory via a study of the presence of potential offenders (as measured by the number of registered sex offenders in the area), as well as community and resident characteristics that measure the presence and types of suitable targets and the existence of guardians and guardianship structures. We find that only the presence of certain types of suitable targets has an influence on the variation in the rate of sex offenses across these communities. Policy implications are discussed. 相似文献

The overwhelming majority of cases of acute subdural hematoma in the forensic setting occur as a result of head trauma. We report a case of sudden unexpected death in a middle-aged woman with a history of arachnoid cyst who had sudden spontaneous onset of severe headache that was rapidly followed by collapse and death. A postmortem multiple-slice computed tomographic scan showed a large acute subdural hematoma associated with hemorrhage into an arachnoid cyst. Subdural hemorrhage is an uncommon but well-described complication of an arachnoid cyst. 相似文献

Preferential Trade Agreements (PTAs) have become the most prevalent form of international trade liberalization in recent decades, even though it remains far from clear what their effects on economies and their key units, firms, are. This paper evaluates the distributional consequences of trade liberalization within industries differentiating two distinct aspects in which trade liberalization could result in higher trade flows: the intensive vs. the extensive margin of trade. In particular, we analyze whether trade liberalization leads to increased trade flows because either firms trade more volume in products they have already traded before (intensive margin) or because they start to trade products they have not traded previously (extensive margin), or both. We test these arguments for the Dominican Republic–Central America–United States Free Trade Agreement (CAFTA-DR) and exporting firms based in Costa Rica for the time-period 2008–2014. The results of our study suggest that the effects of CAFTA-DR depend not only on whether we analyze the extensive versus the intensive margin of trade but also whether the product in question is homogenous or differentiated and whether the exporting firm under analysis is small or large. In particular, we find support for the theoretical expectation that firms exporting heterogeneous products, such as textiles, gain from trade agreements, such as CAFTA-DR, in that they can export more varieties of their products. Yet at the same time, they tend to lose at the intensive margin by a reduction in their trade volume while the opposite pattern occurs for firms exporting homogenous products. 相似文献

Although the influence of government regulation on organizations is undeniable, empirical research in this field is scarce. This article investigates how the understanding of and attitudes toward government regulation among public, nonprofit, and for‐profit managers affect organizational performance, using U.S. nursing homes as the empirical setting. Findings suggest that managers’ perceptions of regulation legitimacy—views of regulation fairness, inspectors’ effectiveness, and internal utility of the mandates—positively affect service quality. Subgroup analysis suggests that managers’ views of regulation matter in nonprofit and for‐profit organizations but not in public organizations. In nonprofit homes, performance declines when managers report higher regulatory expertise—better knowledge of the regulatory standards. In for‐profit facilities, frequent communication with regulators lowers quality. These findings suggest that the regulated entities’ views of government regulation are central to their success, which necessitates improvements in the regulatory process. 相似文献

Tremendous attention has been paid to local election administration since the 2000 presidential election meltdown, yet policy makers still lack basic information about what happens at the polling place. One strategy to understand the interactions between citizens and street‐level election bureaucrats is to turn to administrative data. Using logs collected by polling place workers, the authors analyze more than 66,000 individual incidents recorded from four different statewide elections. Such data provide novel insights and guidance for the administration of elections. Findings indicate that task scale (in terms of the number of ballots) and complexity (in terms of absentee ballots) increase the incident rate. Managerial choices about how polling places are run also matter: the use of electronic voting machines and central count processing of ballots reduce the incident rate, while splitting poll worker shifts increases it. Operator capacity, measured in terms of experience, also reduces the number of incidents. 相似文献

Treating Words as Data with Error: Uncertainty in Text Statements of Policy Positions 总被引:1,自引:0,他引:1

Political text offers extraordinary potential as a source of information about the policy positions of political actors. Despite recent advances in computational text analysis, human interpretative coding of text remains an important source of text-based data, ultimately required to validate more automatic techniques. The profession's main source of cross-national, time-series data on party policy positions comes from the human interpretative coding of party manifestos by the Comparative Manifesto Project (CMP). Despite widespread use of these data, the uncertainty associated with each point estimate has never been available, undermining the value of the dataset as a scientific resource. We propose a remedy. First, we characterize processes by which CMP data are generated. These include inherently stochastic processes of text authorship, as well as of the parsing and coding of observed text by humans. Second, we simulate these error-generating processes by bootstrapping analyses of coded quasi-sentences. This allows us to estimate precise levels of nonsystematic error for every category and scale reported by the CMP for its entire set of 3,000-plus manifestos. Using our estimates of these errors, we show how to correct biased inferences, in recent prominently published work, derived from statistical analyses of error-contaminated CMP data. 相似文献

One line of research finds the size of the deficit to be positively correlated with the number of political actors. This ‘political fragmentation’ hypothesis has been tested on OECD countries. We successfully replicate Volkerink and de Haan’s (Public Choice 109:221–242, 2001) model on an OECD sample. However, when we add ten non-OECD countries, the effect of political fragmentation disappears. We argue that the importance of political fragmentation varies according to the institutionalization of political systems. When we interact the age of a democracy with political fragmentation, we find that legislative fractionalisation increases the budget deficit as a democracy becomes more institutionalised. 相似文献

Abstract: Forensic organizations worldwide have recommended that dental prostheses should be labeled with at least the patient's name and preferably with further unique identifiers such as social security number, etc. The practice of denture marking has been conducted over many years and several denture marking systems have been reported in the dental literature. However, very little is known about the resilience of such systems to conditions experienced in the majority of post- and perimortem assaults. The purpose of this investigation therefore, was to expose a selection of 10 denture labels to a series of hostile environments. Results of the study indicate that the majority of the denture labeling systems appear capable of withstanding a range of common, and not so common postmortem assaults. With regard to thermal insult, however, most performed badly with the exception of a label constructed from stainless steel orthodontic band. However, another label in the form of an electronic RFID-tag performed above expectations in the majority of experiments. Furthermore, its cosmetic appearance has proven most popular with many patients. 相似文献
