Fentanyl has emerged as the most prolific drug in the ongoing opioid epidemic and has greatly impacted traffic safety in recent years. This study aimed to evaluate fentanyl prevalence and concentrations in blood and oral fluid in driving under the influence of drugs (DUID) cases in three different regions (i.e., Alabama, Orange County, CA, and Houston, TX) from 2017 to 2022. Furthermore, traffic fatalities were evaluated for Alabama and Orange County, CA. Fentanyl positivity in DUID and traffic fatalities increased for most years in this study. In Alabama, the prevalence of fentanyl DUID cases increased 4-fold in 2022 compared to 2017. Orange County's increase from 2017 to 2022 was 14-fold. In Houston, the increase was approximately 2-fold from 2019 to 2022. The greatest increase for all laboratories coincided with the start of the COVID-19 pandemic. In 2022, the median fentanyl DUID blood concentrations were 4.7, 11, and 4.7 ng/mL in Alabama, Orange County, and Houston, respectively. Most fentanyl cases were polydrug cases (≥90%). Methamphetamine, THC, and alprazolam were the most frequently detected drugs in combination with fentanyl. Alabama has collected oral fluid and blood in DUID cases since 2018. The detection of fentanyl in oral fluid was comparable to blood. However, 59% and 8.7% of fentanyl-positive cases had concentrations of >20 ng/mL in oral fluid and blood, respectively. Therefore, oral fluid as an alternative or supplemental specimen to blood is an attractive approach for fentanyl in DUID cases. This study contributes to understanding recent fentanyl trends and their impact on traffic safety. 相似文献

Congressional Attacks on the Supreme Court: A Mechanism to Maintain,Build, and Consolidate 下载免费PDF全文
Curt Nichols 《Law & social inquiry》2016,41(1):100-125
Reexamination and reinterpretation of the “mature” (1955–1984) New Deal era of congressional attacks on the Supreme Court reveals a new hypothesis: that Court‐curbing efforts played a previously unrecognized role in party system development. Court rulings that create inter‐ and intraparty tension provide opportunities for various actors to attack the Court in an effort to solidify their faction's standing within national coalitional politics. Congressional attackers can use Court‐curbing resolutions and amendments in efforts to help them maintain coalitional cohesion, build a new majority, or consolidate previous victories. Thus, we might see legislative‐judicial relations as an unrecognized “site” of political development, where coalitional change is opposed and wrought. 相似文献

Advocates claim that the sequential lineup is an improvement over simultaneous lineup procedures, but no formal (quantitatively
specified) explanation exists for why it is better. The computational model WITNESS (Clark, Appl Cogn Psychol 17:629–654,
2003) was used to develop theoretical explanations for the sequential lineup advantage. In its current form, WITNESS produced
a sequential advantage only by pairing conservative sequential choosing with liberal simultaneous choosing. However, this
combination failed to approximate four extant experiments that exhibited large sequential advantages. Two of these experiments
became the focus of our efforts because the data were uncontaminated by likely suspect position effects. Decision-based and
memory-based modifications to WITNESS approximated the data and produced a sequential advantage. The next step is to evaluate
the proposed explanations and modify public policy recommendations accordingly. 相似文献

The reporting of a likelihood ratio (LR) calculated from probabilistic genotyping software has become more popular since 2015 and has allowed for the use of more complex mixtures at court. The meaning of “inconclusive” LRs and how to communicate the significance of low LRs at court is now important. We present a method here using the distribution of LRs obtained from nondonors. The nondonor distribution is useful for examining calibration and discrimination for profiles that have produced LRs less than about 104. In this paper, a range of mixed DNA profiles of varying quantity were constructed and the LR distribution considering the minor contributor for a number of nondonors was compared to the expectation given a calibrated system. It is demonstrated that conditioning genotypes should be used where reasonable given the background information to decrease the rate of nondonor LRs above 1. In all 17 cases examined, the LR for the minor donor was higher than the nondonor LRs, and in 12 of the 17 cases, the 99.9 percentile of the nondonor distribution was lower when appropriate conditioning information was used. The output of the tool is a graph that can show the position of the LR for the person of interest set against the nondonor LR distribution. This may assist communication between scientists and the court. 相似文献

Almost all European countries suffer from mass unemployment. More than 20 million persons in Europe are out of work. When
the unemployment rate reaches such levels it can be assumed that it has implications not only for each unemployed individual
but also for society as a whole. In this article, a distinction is made between unemployment as a private trouble and unemployment
as a public issue. This distinction with regard to unemployment was introduced by Mills (1959) and illuminates the different,
although interrelated, effects of unemployment on the individual and on the overall structure of society. The private trouble
perspective raises the question of how individuals are affected by unemployment and the public issue examaines how unemployment
affects society as a whole. We apply the reasoning by first discussing the relations between individual consequences of unemployment.
We focus on two often neglected aspects, namely, economic hardship and shame. Then the implications for working life and society
are discussed. There is much evidence indicating that the social and health consequences of unemployment are not limited to
the unemployed and their families but also affect the working life and the overall structure of society. It is argued that
mass unemployment might increase the process of social disintegration in society. 相似文献
