Are America’s public mass shooters unique? A comparative analysis of offenders in the United States and other countries

Public mass shooters are often assumed to be an exceptionally American problem, but little is known about what proportion of global offenders attack in the United States, or how America’s offenders compare to those in other countries. The present study offers the first quantitative analysis of all known offenders from 1966 to 2012 who attacked anywhere on the globe and killed a minimum of four victims. The results suggest that public mass shooters in the United States are significantly more likely to arm themselves with multiple weapons and attack at school and workplace settings, while offenders from other countries are more likely to strike at military sites. These differences may be partially attributable to America’s national gun culture and its particular set of social strains.     

Total Body Mass Estimation from Anthropometric Measurements in Modern Young Adult U.S. Populations with Healthy Body Fat Percentages (NHANES III)

This study presents a method by which to estimate total body mass in modern young adult U.S. populations who self‐identified as non‐Hispanic U.S. White, non‐Hispanic U.S. Black, and Mexican American with anthropometric measurements from the Third National Health and Nutrition Examination Survey (NHANES III) 1988–1994 dataset (N = 2532). Correlations of stature and bi‐iliac breadth with total body mass were stronger among males (r = 0.717–0.774) than among females (r = 0.549–0.661), yet these results were more accurate assessments of total body mass than existing techniques. This study also examined additional anthropometric measurements to estimate total body mass using an information‐theoretic approach demonstrating that some error in the stature–bi‐iliac breadth method is attributed to a nonsupported model with multimodel inference. The limitations of the current total body mass technique are discussed as well as the need for future studies to validate the method.     

Counterfeit Adderall Containing Aceclofenac from Internet Pharmacies

A nontargeted approach based on liquid chromatography equipped with a quadrupole time‐of‐flight mass detector (LC‐MS Q‐TOF) joined to nuclear magnetic resonance (NMR) analysis allowed rapid identification and quantification of the anti‐inflammatory drug aceclofenac in illegal Adderall tablets. The largest chromatographic peak had m/z = 354.030 and m/z = 376.012 matching, respectively, the ionic structures (M + H)⁺ and (M + Na)⁺ of a molecule M. The accurate mass data generated the molecular formula C₁₆H₁₃Cl₂NO₄. A screening of the pharmaceutical active substances having that molecular formula together with the MS/MS fragmentation pattern suggested aceclofenac. Aceclofenac structure was unambiguously confirmed by ¹H and ¹³C NMR experiments. The aceclofenac content was 90 mg/tablet (RSD 2%) as detected by quantitative NMR. Information on the identity and content of illegal drugs is required for legal purposes; it supports in evaluating the effective impact on users safety, and it is useful for control laboratories using a targeted approach in their analytical activities.     

Perceived accountability and public attitudes toward local police

Recent national events have brought the issue of police-community relations into the public eye. Even though a large body of academic research exists on the predictors of public attitude toward police, very little is known about how public perceptions of police accountability influence satisfaction with the police. This study seeks to fill that gap by using ordered logistic regression and multi-year community-level survey data from one Western city (n = 3725) to examine the relationship between satisfaction with police accountability and overall attitudes toward the police. The results indicate that respondent satisfaction with police accountability was a strong, consistent predictor of satisfaction with local police, even after controlling for other important variables, such as race/ethnicity and community context. The findings suggest that public perceptions relating to the control of police officer conduct should be considered when assessing the predictors of attitudes toward the police.     

论我国当前群防群治工作

群防群治是我国社会治安综合治理的重要力量。建国后,国家群防群治工作从实践到理论进行了长期的探索。改苹开放后,群防群治工作有了新的特点和变化,面临新的机遇和挑战。当前全国各地群防群治队伍形形色色,但是基本可以归结为四类,这四类群防群治队伍的组织形式、管理模式、工作内容职责、经费保障有的有规范性文件依据,有的还没有规范性文件依据,实践中作法缺乏统一。当前推动群防群治工作需要做的工作很多,其中通过立法统一、完善群防群治各项工作,加强人防与物防和技防的结合,保障经费,明确工作职责是关键。     

论群体性事件处置中的说服艺术

群体性事件基本上属于人民内部矛盾.因此,公安机关在处置过程中.应最大限度地运用解决人民内部矛盾的方法和手段.群体性事件处置中说服的条件是事件态势处于相对控制之下,说服的原则主要有平等性原则、针对性原则、可信性原则和感染性原则.说服方法有标签效应法、"自己人"效应法、亲情效应法和威信效应法等.     

群体性事件的成因与对策探析

市场经济的建设呼唤着民主进程的加速推进,它一方面唤醒了民众的主体维权意识,另一方面过渡膨胀的主体意识,又诱发了大量的群体性事件的发生。在转型期社会中,为了有效控制群体性交发事件发生：一要保持畅通的公力救济渠道;二要坚持社会公平的制度取向,防止贫富差别日益扩大;三要转变政府职能,规范政府行为,切实维护群众利益;四要建立起相应的利益表达机制。     

Attributions of Negative Partner Behavior by Men Who Physically Abuse Their Partners

This study investigated the association between family violence and the attributions made for negative partner behaviors in an Australian context. Three groups of men were classified as physically violent (in counseling), non-physically violent (in counseling), and non-physically violent (in the community). The Relationship Attribution Measure was used to assess the attributional dependent variables of locus, stability, globality, intent, motivation, and blame. Significant differences between violent and nonviolent men on each of the attributional dimensions were found. Physically violent men were more likely than non-physically violent men (counseling) to attribute the negative behavior of their partners to unchangeable, intentional rather than unintentional, selfishly motivated, and blameworthy causes. However, these differences disappeared when marital satisfaction was controlled. The implications of this work for domestic violence intervention programs are discussed, along with a number of methodological issues and directions for future research.     

The Implications of Framing Effects for Citizen Competence

Social scientists have documented framing effects in a wide range of contexts, including surveys, experiments, and actual political campaigns. Many view work on framing effects as evidence of citizen incompetence—that is, evidence that citizens base their preferences on arbitrary information and/or are subject to extensive elite manipulation. Yet, we continue to lack a consensus on what a framing effect is as well as an understanding of how and when framing effects occur. In this article, I examine (1) the different ways that scholars have employed the concepts of framing and framing effects, (2) how framing effects may violate some basic criteria of citizen competence, and (3) what we know about how and when framing effects work. I conclude that while the evidence to date suggests some isolated cases of incompetence, the more general message is that citizens use frames in a competent and well-reasoned manner.
