Illicit fentanyl has flooded the United States' drug market, increasing the risk of overdose and poisonings throughout the general population and accidental exposure among law enforcement officers confiscating the increasing number of seizures. Fentanyl test strips (FTS) are used to obtain presumptive information about the presence of fentanyl in a suspected sample. However, their adoption by law enforcement personnel and seized-drug analysts has been limited because most products are advertised for urine testing, not for assays using water solutions. This study presents an evaluation of four commercial FTS: Rapid Response from BTNX, Inc.; T-Dip Fentanyl (FTY) Urine Dip Cards obtained from Amazon.com ; Premier BioDip FYL10 from Premier Biotech Inc.; and MobileDetect Fentanyl strips from DetectaChem, Inc. Performance characteristics curves were used to compare the products' sensitivity, showing that all can reliably detect fentanyl in aqueous solutions at concentrations below 1 μg/mL, with some of the tests able to reliably detect the drug at 200 ng/mL. A stability study demonstrates the performance of all four FTS brands was only slightly affected after 30 days of storage at two extreme environmental conditions. Fentanyl-related substances are also evaluated using the Rapid Response FTS, which showed high cross-reactivity with para-fluorofentanyl and acetylfentanyl, but lower with ortho-chlorofentanyl, carfentanil, and 4-ANPP. Users should be aware that FTS may give false-negative results even when potentially dangerous levels of carfentanil are present. When testing other common drugs, adulterants, and diluents frequently encountered in seized tablets, concentration-dependent results were obtained and multiple instances of false positives were recorded. 相似文献
According to German family law, in family court proceedings that deal with custody or access rights, family judges are obligated to personally hear the child if the feelings, ties, or will of the child are significant for the decision. In a research study commissioned by the Federal Ministry of Justice, a nationwide representative survey of all judges compiled their personal information and their attitudes and expectations as well as various parameters regarding the concrete practice of hearing children. Also, with a very complex methodological design, over 50 children and their parents were studied one week in advance of the hearing, directly before and after the hearing, and four weeks following the hearing. The results of the study are presented, particularly those pertaining to the burden and relief for the children and the expectations of judges. The practical experiences of family judges in personally hearing children are included as well. 相似文献
The purpose of this study is to compare and contrast attitudes of Mississippi inmates who participate in a conjugal visitation
program with inmates who do not participate in such a program. Logistic regression analyses reveal no differences between
participant and nonparticipant attitudes toward the conjugal visitation program. However, differences exist among gender and
racial lines and several of the attitudinal issues regarding the program. Policy implications are also addressed. 相似文献
Based on a qualitative study of the United States federal compensatory education policy, Title I of the Elementary and Secondary Education Act, this article uses interpretive policy analysis to investigate the ways in which policy language influences practitioners' understanding of students who are eligible for policy-funded services. Focusing on the situated interpretations of practitioners in nine urban elementary schools, the study shows how policy-generated categories shape practitioners' conceptualizations of students as they determine how to provide services. The aricle considers possible consequences of policy labels on teacher expectations and ends with an appeal for the collective, reflective interrogation of policy language in educational practice. 相似文献
In recent years, students of voting behavior have become increasingly interested in valence politics models of electoral choice. These models share the core assumption that key issues in electoral politicds typically are ones upon which there is a widespread public consensus on the goals of public policy. The present paper uses latent curve modeling procedures and data from a six-wave national panel survey of the American electorate to investigate the dynamic effects of voters’ concerns with the worsening economy—a valence issue par excellence—in the skein of causal forces at work in the 2008 presidential election campaign. As the campaign developed, the economy became the dominant issue. Although the massively negative public reaction to increasingly perilous economic conditions was not the only factor at work in 2008, dynamic multivariate analyses show that mounting worries about the economy played an important role in fueling Barack Obama’s successful run for the presidency. 相似文献
This systematic literature review analyses how public servants apply workplace creativity to come up with ideas for public sector innovations, defining public sector creativity and analyzing its practices, features, trends, and hiatuses in knowledge for which we provide a future research agenda. Creativity is the origin of innovation. Public sector creativity, however, is theoretically undefined and underexamined, resulting in unclarity on what constitutes public sector creativity. We define public sector creativity as “public servants coming up with novel and useful ideas through various practices.” Our findings indicate that public servants apply at least six taxonomically distinctive creative practices, and although they are involved to different extent in generating the initial idea and thus do not always generate ideas autonomously, they are creative in finding alternative ways to come up with ideas. However, our review indicates hiatuses in knowledge on public sector creativity, for which we provide a future research agenda. 相似文献
The problem of intimate partner homicide is featuring increasingly on national and international policy agendas. Over the last 40 years, responses to this issue have been characterised by preventive strategies (including ‘positive’ policing; the proliferation of risk assessment tools, and multi-agency working) and post-event analyses (including police inquiries and domestic homicide reviews). In different ways, each of these responses has become ‘locked in’ to policies. Drawing on an analysis of police inquiries into domestic homicides in England and Wales over a 10-year period, this paper will explore the nature of these ‘locked in’ responses and will suggest that complexity theory offers a useful lens through which to make sense of them and the ongoing consistent patterning of intimate partner homicide more generally. The paper will suggest this lens in embracing what is known and unknown affords a different way of thinking about and responding to this problem.
