Why do people support gun control?: Alternative explanations of support for handgun bans

Many scholars have suggested that Americans' positions on gun control are the product of culture conflicts. This assertion has been largely based on associations of gun control opinion with membership in social groups believed to be hostile, or favorable, towards gun ownership, rather than with direct measures of the cultural traits thought to mediate the effects of group membership on gun control opinion. Data from a 2005 national telephone survey were analyzed to test competing theories of why people support handgun bans. Instrumental explanations, which stress belief in a policy's likely effectiveness, accounted for less than 25 percent of the variation in support. The results supported the culture conflict perspective. Those who endorsed negative stereotypes about gun owners, and who did not believe in the need to defend their own homes against crime (versus relying on the police) were more likely to support handgun bans.     

Detection of Tooth‐Colored Restorative Materials for Forensic Purposes Based on Their Optical Properties: An In Vitro Comparative Study

Victim identification using dental records involves antemortem and postmortem comparison of dental charts. Since dental restorations may be part of such records, identifying them accurately is critical. The objective of this study was to compare the diagnostic reliability and validity of two optical methods for identifying tooth‐colored restorations (digital imaging fiber optic transillumination (DiFOTI) using near infrared light, and fluorescence‐aided identification of restorations (FAIR)) with conventional diagnostic methods. Four examiners identified and charted tooth‐colored restorations in three sets of typodonts on the bench using conventional visual and tactile examination, DiFOTI (DIAGNOcam?) and FAIR. All examinations were repeated after 4 weeks. Both the sensitivity (95%) and specificity (97%) of the FAIR method were significantly higher than those for DiFOTI (82% and 82%) and for conventional inspection (71% and 82%). In conclusion, FAIR method performed better than conventional examination and DiFOTI, and was more reliable for identifying tooth‐colored restorations.     

Combined DNA Typing and Protein Identification from Unfired Brass Cartridges,,,

Biological evidence analysis from contact traces is adversely affected by low quantity and quality of DNA. Proteins in these samples contain potentially individualizing information and may be particularly important for difficult surfaces such as brass, where DNA may yield incomplete profiles. In this study, touched unfired brass cartridges were sampled using dry tape or wet swabs and analyzed by separating DNA and protein from the same collected material, thus producing both genomic and proteomic information. DNA recovery was similar for both collection methods, with tape yielding an average of 1.36 ± 1.87 ng and swabs, 1.34 ± 3.04 ng. Analysis by mass spectrometry identified 95 proteins, with the two collection methods showing no significant difference (p = 0.76) in the average number of collected proteins: 44.5 ± 10.9, (tape) versus 47.9 ± 20.4 (swabs). Proteins can be collected from fingerprints at levels necessary to provide identifying information, thus expanding information obtained from challenging evidence.     

Does business influence government regulations? New evidence from Canadian impact assessments

Regulatory impact assessments frequently embed stakeholder consultations in their design. Canada was one of the early adopters of such an approach and therefore has systematic documentation on the actors taking part in these consultations. This article asks whether these consultations have an influence on regulatory change and whether business disproportionally benefits from them. After converting the documentation into data, we find that these consultations do in fact matter: the more diversified the stakeholders taking part, the more stringent the changed regulations. But we also found that for a subset of regulatory changes, those likely to carry high economic stakes, business takes advantage of the consultation, often obtaining some reduction in regulatory stringency. These reductions, however, are conditioned on the limited presence of opposing views expressed during the consultations.

The Revised German Raw Materials Strategy in the Light of Global Political and Market Developments

Raw material markets have proven to be challenging in recent years. The so‐called critical raw materials (CRMs), which are required for green technology, have particularly high environmental and supply risks. The revised German raw materials strategy attempts to address challenges of production and supply of CRMs and other mineral‐based raw materials. This contribution analyzes the motivation, measures, goals, and challenges of the German raw materials strategy in the light of global economic and political developments, applying the qualitative method GABEK®. Results show that the revised strategy is more ambitious and reaches farther than the initial strategy of 2010. Challenges that remain include the lack of willingness of the German industry to engage in mine production and the more pro‐active political approaches demonstrated elsewhere. As all major economic powerhouses outside of Europe pursue a hands‐on approach, it remains questionable if the revised German raw materials strategy will fundamentally be able to sustainably secure raw material supply for the German industry.     

Regulatory Categorization and Arbitrage: How Daily Fantasy Sports Companies Navigated Regulatory Categories Before and After Legalized Gambling

This article uses the context of daily fantasy sports (DFS) to analyze how companies use strategic categorization in regulatory arbitrage. Recent actions by two leaders in the DFS industry, DraftKings and FanDuel, provide an ideal context to study this issue. DraftKings and FanDuel categorized themselves differently to different audiences at different times in a manner that evaded categorization as an illegal gambling activity, only to then dominate the sports betting market after the Supreme Court's decision in Murphy v. NCAA. We examine how this type of strategic categorization, which we call “fluid categorization,” raises important questions for regulators and others concerned with regulatory arbitrage. We also explore how fluid categorization provides lessons for other businesses. While this article has broad implications for the sports gambling marketplace, it also contributes to meaningful discourse for the broader business community, as its findings are relevant to industries beyond DFS that offer gray market products and seek to fight categorical labels until there is a reclassification event.     

Assaultive behavior in state psychiatric hospitals: differences between forensic and nonforensic patients

Forensic patients are occupying an increasingly large number of beds in state psychiatric hospitals. The presence of these mentally ill offenders has raised concerns about the risk they present to nonforensic patients. This study compared the rate of assaults and factors associated with assaultive behavior among 308 nonforensic patients and two groups of forensic patients including 469 patients found not guilty by reason of insanity and 76 pretrial patients. Consistent with other studies, nonforensic patients had higher rates of assaults than either group of forensic patients. However, being a forensic patient did not affect the odds of assault when controlling for the effects of demographic and clinical variables in a multivariate logistic regression analysis. Factors associated with assaults in each of the three patient groups were identified using multivariate analyses. Implications are presented for treatment of assaultive behavior, mixing of forensic and nonforensic patients within state hospitals, forensic release policies, and future research.     

Colchicine poisoning: case report of two suicides

Colchicine overdose is uncommon but potentially life threatening because of the high toxicity of the drug. Poisoning by colchicine may occur following ingestion of medication used in acute attacks of gout and inflammatory diseases. We describe two cases involving suicide by the ingestion of medications marketed in France. In case 1, only heart blood was taken after body external examination. In case 2 an autopsy was performed and heart blood, urine, gastric contents and bile were taken for toxicological analysis. Colchicine was assayed in biological specimens by an HPLC-DAD method, after extraction by dichloromethane at pH 8, adding prazepam as internal standard (IS). Analyses were performed on a Symetry C-8 column. Mobile phase was a gradient of acetonitrile/pH 3.8 phosphate buffer. Colchicine is eluted at 13.1 min and the method is linear for blood, urine and bile over the range 4-1000 ng/mL. LOQ is 4 ng/mL. The concentrations of colchicine detected are: case 1: heart blood 13 ng/mL; case 2: heart blood 66 ng/mL, urine 500 ng/mL, gastric content 12 ng/mL, bile 5632 ng/mL. Our findings are in the range of lethal concentrations previously described, but there is no correlation with the amount of ingested drug. Even after massive overdose, it could be impossible to detect colchicine in blood, and as there is a widespread enterohepatic recirculation before excretion in bile and feces, bile is the target sample to analyse. We conclude in both cases that the cause of death was suicide with colchicine. It appears very important to perform an autopsy in order to obtain bile, urine, heart blood and femoral blood.
