Justin Michel M.D. M.Sc. Arnaud Paganelli M.D. M.Sc. Arthur Varoquaux M.D. M.Sc. Marie‐Dominique Piercecchi‐Marti M.D. Ph.D. Pascal Adalian Ph.D. Georges Leonetti M.D. Ph.D. Patrick Dessi M.D. M.Sc. 《Journal of forensic sciences》2015,60(2):269-273
Frontal sinuses (FSs) have been studied in radiology, anthropology, and forensic anthropology. This study aimed to determine whether it was possible to predict the age and sex of an individual using FS volume. Sixty‐nine anonymized CT scans were imported to MIMICS 10.01® software (Materialise N.V.), and each FS volume was calculated in mm3. There was an absence of significant difference between right and left FS volume (p = 0.173) and an absence of correlation between age and FS volume (Pearson's test; p = 0.705). Sexual dimorphism was significantly different (p = 0.001). However, the most discriminant datum for determining sex was found to be the total FS volume (sum of an individual's right and left FS volumes) with linear discriminant Fisher's function coefficients of ?2.759 for the male group and ?1.275 for the female group. With this model, 72.5% of our sample was correctly classified according to sex. 相似文献

Testing What Matters (If You Must Test at All): A Context‐Driven Approach to Substantive and Statistical Significance 下载免费PDF全文
Justin H. Gross 《American journal of political science》2015,59(3):775-788
For over a half century, various fields in the behavioral and social sciences have debated the appropriateness of null hypothesis significance testing (NHST) in the presentation and assessment of research results. A long list of criticisms has fueled the so‐called significance testing controversy. The conventional NHST framework encourages researchers to devote excessive attention to statistical significance while underemphasizing practical (e.g., scientific, substantive, social, political) significance. I introduce a simple, intuitive approach that grounds testing in subject‐area expertise, balancing the dual concerns of detectability and importance. The proposed practical and statistical significance test allows the social scientist to test for real‐world significance, taking into account both sampling error and an assessment of what parameter values should be deemed interesting, given theory. The matter of what constitutes practical significance is left in the hands of the researchers themselves, to be debated as a natural component of inference and interpretation. 相似文献

The “Europeanization” of the Basel process: Financial harmonization between globalization and parliamentarization 下载免费PDF全文
Public policy initiatives aimed at the prevention of future financial crises originate with global harmonization in the form of executive standards issued by the Basel Committee on Banking Supervision. This article explores the role of the European Parliament (EP) in the process of adapting the standards in European Union legislation passed in 2013 as the Capital Requirements Regulation/Capital Requirements Directive IV. Unlike accounts casting the EP as increasingly dependent upon outside sources in order to meet its enhanced legislative role, we find it increasingly dexterous in developing and using in‐house policy ideas, expertise, and not least a common sense of institutional purpose. Notable EP successes in final legislation include (but are not restricted to) a headline cap on bankers' bonuses in the face of entrenched business and national interests. The argument is developed by drawing upon a broad range of interviews together with other primary and secondary sources, tracing the contribution of the EP from the early stages of agenda‐setting through to the development of an “esprit de corps” among the committee lead team which survived intact throughout the “black box” of trilogue negotiations. Besides illuminating the notoriously opaque trilogue process, the analysis also contributes to contemporary debates about whether the EP's increased legislative powers are resulting in a shift away from its traditional allegiances with diffuse interests toward a greater engagement with producer sources in order to fulfill requirements for policy expertise. 相似文献

The police murder of George Floyd sparked nationwide protests in the summer of 2020 and revived claims that public outcry over such high-profile police killings perpetuated a violent “war on cops.” Using data collected by the Gun Violence Archive (GVA) on firearm assaults of U.S. police officers, we use Bayesian structural time series (BSTS) modeling to empirically assess if and how patterns of firearm assault on police officers in the United States were influenced by the police murder of George Floyd. Our analysis finds that the murder of George Floyd was associated with a 3-week spike in firearm assaults on police, after which the trend in firearms assaults dropped to levels only slightly above that which were predicted by pre-Floyd data. We discuss potential explanations for these findings and consider their relevance to the contemporary discussion of a “war on cops,” violence, and officer safety. 相似文献

The Scary World of Online News? Internet News Exposure and Public Attitudes Toward Crime and Justice
Sean Patrick Roche Justin T. Pickett Marc Gertz 《Journal of Quantitative Criminology》2016,32(2):215-236
Objectives
A substantial body of literature indicates that certain forms of media consumption may increase anxiety about crime and support for social controls. However, few studies have examined whether Internet news consumption is positively associated with such attitudes. The void is significant given the public’s increasing use of online news sources. This study addresses this research gap.Methods
We draw on data from four national surveys conducted between 2007 and 2013, which collectively include interviews with more than 13,000 Americans. Using OLS and logistic regression, we assess the relationships between exposure to traditional and online media and perceptions of victimization risk, support for punitive crime policies, and views about police powers.Results
Consistent with prior work, we find positive relationships between exposure to traditional forms of media—television news and crime programming—and anxiety about victimization and support for harsh crime policies. In contrast, Internet news exposure is generally not associated with anxieties about crime or support for getting tough on criminals. However, there is evidence of an interactive relationship between political ideology and Internet news exposure.Conclusions
The results provide little support for cultivation theory in the context of Internet news consumption. We discuss the import of our findings, and suggest new lines of research to explore the correlates and the effects of exposure to online news sources.297.
