Objectives
This study considers the social determinants of twenty-first century punitive American views.Methods
Using General Social Survey data for 2000 and 2014, this research seeks to replicate Unnever and Cullen’s analysis of the determinants of punitive American views in 2000, extend their analysis to consider animus toward the poor as a predictor of punitive views, and consider the social foundations of punitiveness in 2014.Results
Our analysis replicates Unnever and Cullen’s (Criminology 48: 99–129, 2010) findings for 2000 and identifies previously obscured indirect effects of anti-Black racial stereotypes on punitiveness. In our extension analyses, animus toward the poor was a significant predictor of punitiveness in 2000. For 2014, we find that anti-Black racial resentment, animus toward the poor, and social anxiety significantly predicted both support for the death penalty and the belief that courts are not harsh enough.Conclusions
The social sources of American punitive views have not shifted fundamentally in the last 15 years. Both racial resentment and animus toward the poor have been and remain powerful predictors of punitive American views in the twenty-first century, controlling for other factors.292.

Forensic pathologist use soot and/or stippling surrounding entrance gunshot wounds in categorizing range of fire. If absent, some pathologists suggest utilizing histology when the range is diagnostically critical. This study investigates the concordance of macroscopic and microscopic findings in estimating range of fire by evaluating gunshot entrance and exit wounds made through human tissue analogs at defined distances using two handgun calibers. Examination of over 150 entrance wounds verified the ease of visually detecting soot from a muzzle distance of contact to 1 foot (30.5 cm), and its absence at 9 feet (274.3 cm). Distinctly apparent was bullet wipe surrounding the entrance wounds regardless of muzzle distance. Although variations existed, dark material was histologically identified in many skin, soft tissue, and bone sections at all ranges with both calibers. These nonparallel results decrease the dependability of histology for range of fire estimation and reinforce using gross observation. 相似文献

Artemisia absinthium (wormwood), a common ingredient in absinthe, contains the compound thujone, which is unregulated by the U.S. Drug Enforcement Agency. Thujone can cause an “unregulated legal high” in higher concentrations. The European Union limits thujone from Artemisia species to 35 mg/kg while the U.S. Food and Drug Administration requires less than 10 ppm to be “thujone‐free.” However, individuals can smoke or ingest A. absinthium in different forms. This study developed a polymerase chain reaction (PCR) high‐resolution melt (HRM) assay to detect and identify A. absinthium based on primer specificity, sensitivity, repeatability, and robustness. A triplex assay was performed with three “unregulated legal high” species: Datura stramonium, Merremia tuberosa, and A. absinthium; the PCR HRM assay detected and identified each plant at melt temperatures 77.42 ± 0.20°C, 83.88 ± 0.22°C, and 87.77 ± 0.15°C, respectively. The primer set developed distinguished A. absinthium from a variety of plant species and was successfully triplexed. 相似文献

A study into the modification of 1,8-diazafluoren-9-one (DFO) formulations by the additions of metal salts into the working solution is reported. Similar additions have been found to increase the fluorescence of marks developed using other amino acid reagents including 1,2-indandione and the ninhydrin analogue 5-methylthioninhydrin. It was found that adding zinc chloride to give a 1:1 ratio of zinc ions:DFO molecules gave optimum fluorescence, and improvements in performance over the standard DFO formulation were achieved. Attempts to produce equivalent formulations with iron, nickel and palladium chlorides were unsuccessful. In a comparative trial with a 1,2-indandione-zinc formulation on brown paper and cardboard substrates, 1,2-indandione-zinc gave superior results and it was decided to focus further research on this reagent instead of DFO-zinc. 相似文献

The disulfur dinitride process for fingermark visualisation was first reported a decade ago, with promising results obtained for a range of materials including metals. However, the friction sensitive nature of the material and difficulty of synthesis made routine use difficult. Many of these issues have since been addressed, making equipment and chemicals available to build an understanding of how the effectiveness of disulfur dinitride compares to other fingermark visualisation processes currently used on metal surfaces. This enables more informed advice to be given on selection of processes for treatment of metal items, an area of operational interest that encompasses weapons used in violent crime and the increasing incidence in metal theft. This paper reports a comparative study into the effectiveness of disulfur dinitride, cyanoacrylate fuming, vacuum metal deposition, gun blueing and wet powder suspensions on brass, bronze, copper and stainless steel. Experiments were conducted with the surfaces exposed to a range of environments including long term ageing, water/detergent washing, acetone washing and high temperature exposure. The results indicate that disulfur dinitride is an effective process for fingermark visualisation on metal surfaces, including those exposed to adverse environments, and may offer potential improvements over existing processes for those surfaces. Further work, including pseudo-operational trials, is recommended. 相似文献

We use Canadian data linking information on venture capital (VC) financing with firm-level administrative data to compare performance of VC-backed and non-VC-backed firms. The richness of the data allows us to incorporate a wide range of firm-level information into creating a control group based on propensity-score matching. In particular, we use typical covariates reflecting firm performance and characteristics (e.g., size, age, industry, location) as well as measures of firm-level innovation such as research and development (R&D) expenditures that are often thought to be associated with the potential for high growth and the probability of receiving VC financing. Our results show R&D expenditures not only attract VC, but are also increased more intensely for VC-backed firms than non-VC-backed counterparts over the short-run. Further, we show VC-backed firms enjoy greater growth in wages and scale over the 5-year period. Overall, our results provide empirical evidence that VC financing is associated with the acceleration of the innovation and commercialization process accompanied by greater growth in wages and scale. 相似文献

As wildlife trafficking or the illegal wildlife trade has taken a more prominent place on the global agenda, discussions are taking place as to how wildlife trafficking happens. An increased understanding has revealed that corruption is a key facilitator of this profitable and pervasive global black market, but limited research has explored exactly what that corruption looks like and how corruption enables wildlife to be trafficked. Furthermore, research shows that Asia, particularly China and Southeast Asia, are focal points for the supply and demand of certain species of wildlife. Through a literature-based investigation, this paper unpacks the role specific acts of corruption play in the trafficking of ivory, reptile skins and live reptiles from, through or to Asia. It is proposed that not only do individual corrupt acts enable wildlife trafficking to happen, but also that corrupted structures (the criminal justice system, and economic and political foundations) in some societies enable trafficking to happen and also increase the resilience of trafficking to reduction measures. In collating detailed data about the forms of corruption facilitating wildlife trafficking, the gaps in knowledge, and therefore the important areas for further research, become evident. 相似文献

Objectives
This short report tests whether altering messages concerning the presentation (i.e., criminal justice actor experience vs. summary of scientific findings) or nature of criminological research findings (i.e., lack of crime control effect vs. collateral consequences) regarding the (in)efficacy of sex offender residence restrictions (SORR) would subsequently affect public support for this policy.Methods
The experimental conditions were presented in a factorial survey delivered to a national online panel, which was subsequently matched to a sampling frame representative of US adults on the basis of gender, age, race, education, ideology, and political interest (N?=?970). Analysis of variance was used to estimate the impact of the experimental manipulations on SORR opposition.Results
Support for SORR was high across all experimental conditions, and no manipulations were statistically associated with variation in opposition to the policy.Conclusions
The results support limited previous research suggesting that the public would continue to support SORR even in the lack of evidence to its effectiveness. This research suggests that altering the presenter or nature of research evidence subsequently produces no opinion change, at least in the form that was executed here. Further research on the mechanisms underlying the recalcitrance of SORR support is necessary.300.
