Researchers struggle to understand the relationship between science and policy positions, especially the complicated interplay among the various factors that might affect the acceptance or rejection of scientific information. This article presents a typology that simplifies and guides research linking scientific information to policy positions. We use the typology to examine how characteristics of both scientific information and policy actors' existing policy positions affect the likelihood of changing, maintaining or reinforcing those policy positions. We analyse data from surveys conducted in 2015 and 2017 of policy actors engaged in contested policy debates over shale oil and gas development in Colorado, US. Our findings confirm expectations that policy actors will most likely maintain and reinforce their policy positions in response to scientific information. Our data also show that changes in policy positions depend on policy actors' risk perceptions, perceived issue contentiousness, networks and experience with science. 相似文献

When interpreting firearm injuries, the distinction between gunshot wounds and shotgun wounds is important, and separation of these categories is typically straightforward. However, .410 bore firearms can make the classification difficult. Shotguns and revolvers that can fire the same .410 bore ammunition are readily available. This study investigates the soot and gunpowder deposits and pellet patterning of these two types of weapons using cartridges specially designed for .410 bore revolvers and standard birdshot pellet ammunition. For both ammunition types, the revolver had more prompt pellet dispersion and positive detection of gunpowder at greater distances compared to the shotgun. Additionally, .410 bore slugs are of similar caliber to many common bullets. In comparing the .410 bore slugs to equivalent bullets, some morphologic differences may be imparted on the skin by the slugs, but the greatest insight into the weapon remained with the retained projectiles. 相似文献

Assessing the Risk of Secondary Transfer Via Fingerprint Brush Contamination Using Enhanced Sensitivity DNA Analysis Methods 下载免费PDF全文

Experiments were performed to determine the extent of cross‐contamination of DNA resulting from secondary transfer due to fingerprint brushes used on multiple items of evidence. Analysis of both standard and low copy number (LCN) STR was performed. Two different procedures were used to enhance sensitivity, post‐PCR cleanup and increased cycle number. Under standard STR typing procedures, some additional alleles were produced that were not present in the controls or blanks; however, there was insufficient data to include the contaminant donor as a contributor. Inclusion of the contaminant donor did occur for one sample using post‐PCR cleanup. Detection of the contaminant donor occurred for every replicate of the 31 cycle amplifications; however, using LCN interpretation recommendations for consensus profiles, only one sample would include the contaminant donor. Our results indicate that detection of secondary transfer of DNA can occur through fingerprint brush contamination and is enhanced using LCN‐DNA methods. 相似文献

We report on a sample of 90 child custody evaluators in the United States, who completed an online questionnaire on their attitudes and beliefs in child custody relocation cases. Findings indicated that the vast majority of participants relied on relevant professional literature and utilized a relocation risk assessment forensic model. Participants found many risk, protective, and specific relocation factors important, but the triad of past parental involvement, support for the other parent, and child's age were afforded the most importance. Participants also reported that the moving parents sought relocation for educational/vocational reasons, to receive support of their extended family, or to remarry, while the nonmoving party most commonly opposed relocation due to fears of interference/damage to the nonmoving parent–child relationship, restrictive gatekeeping, and alienation. A common trend among participants was concerns over the possible detrimental impact of any relocation on the nonmoving parent–child relationship and quality of co‐parenting. The vast majority of participants reported that they made specific recommendations to the court about relocation, and the court agreed with their recommendation the overwhelming majority of the time. We discuss Implications of the findings as well as areas needing further research. 相似文献
