Motivational interviewing (MI) is a communication style focused on enhancing clients’ own motivation towards change. In the justice system MI has evidence to support that it enhances communication and change behaviors in youth. As most MI training is designed for healthcare settings training and implementation of MI must be adapted to fit the juvenile justice model. This includes both rehabilitation and restorative justice. Here we describe the details that allowed one county small county in Pennsylvania to roll out MI training and initial skills review in less than 6 months. The case reviews the details of planning, trainings, and timing of activities. We then discuss what elements of those details fit into a greater implementation plan that may be applied elsewhere. Four key elements were instrumental to implementation: 1) appreciation of JPO time constraints, 2) cost containment 3) using blending to enhance JPO flexibility with MI use, and 4) policies that normalize use of MI. This outline may assist other courts in their own implementation efforts. 相似文献

Novel psychoactive substances (NPS) are synthetic drugs that pose serious public health and safety concerns. A multitude of NPS have been identified in the United States, often implicated in forensic investigations. The most common and effective manner for identifying NPS is by use of mass spectrometry and the true utility lies within nontargeted acquisition techniques. During this study, a liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) assay was developed, validated, and implemented for forensic toxicology testing. A SCIEX TripleTOF™ 5600 + with SWATH® acquisition was used. Resulting data were compared against an extensive library database containing more than 800 compounds. The LC-QTOF-MS assay was applied to the reanalysis of biological sample extracts to discover emergent NPS. More than 3,000 sample extracts were analyzed, and more than 20 emerging NPS were detected for the first time. Among these were isopropyl-U-47700, 3,4-methylenedioxy-U-47700, fluorofuranylfentanyl, N-methyl norfentanyl, 2F-deschloroketamine, 3,4-methylenedioxy-alpha-PHP, eutylone, and N-ethyl hexedrone. 相似文献

ABSTRACTRecently, “problem-solving” courts have been developed as an alternative to imprisonment. They are often called “specialty” courts because they process and divert into treatment programs offenders who are seen as different from the general criminal population, such as those with mental health or drug problems, those who are homeless or veterans, and those who engage in domestic violence. Based on a 2017 national survey of 1,000 respondents, the current study examines overall public support for rehabilitation as a goal of corrections and then focuses specifically on support for different types of specialty courts. The analysis reveals that the American public endorses not only the rehabilitative ideal but also the use of problem-solving courts. Further, with only minimal variation, strong support for these courts appears to exist regardless of political orientation and sociodemographic characteristics. 相似文献

This article describes how issue specialization through deliberative institutions called “issue publics” can improve the quality of democratic decision making. Issue specialization improves decisions by instantiating a cognitive division of labor among the mass public, which creates efficiencies in decision making and grants large groups of average citizens a scalable advantage over small groups of even the smartest and most capable individuals. Issue specialization further improves decisions by capturing issue-specific information, concentrating it within the specialized deliberative enclaves of issue publics, and refining citizens’ issue preferences. These advantages are brought to bear in wider democratic politics and policy through information shortcuts and through the specialized electoral incentives of representatives. The article responds to concerns about political ignorance, polarization/partisanship, rent seeking, and socioeconomic bias and argues that issue specialization can provide a valuable brake to polarization yet needs institutional supplementation to engage marginalized citizens and combat bias. 相似文献

AbstractThis study applies moral foundations theory to capital juror decision making. We hypothesized that binding moral foundations would predict death qualification and punitive sentencing decisions, whereas individualizing moral foundations would be associated with juror disqualification and a leniency effect. Additionally, we considered whether moral foundations can explain differences in death penalty application between conservatives and liberals. Respondents from two independent samples participated in a mock-juror task in which the circumstances of a hypothetical defendant’s case varied. Results revealed moral foundations were strong predictors of death qualification. The binding and individualizing foundations were related to sentencing decisions in the expected ways. Supporting our contention that moral foundations operate differently across different types of cases, heterogeneity in the effects of moral foundations was observed. Finally, we found support for the hypothesis that the relationship between sentencing decisions and conservatism would be attenuated by moral foundations. 相似文献

As the emergence of nongovernmental conservation efforts generates conflict among various stakeholders, the causal story that each party articulates regarding conservation and the causes of land degradation reflects their unique interests. This study uses existing literature to evaluate causal stories surrounding a contemporary conservation effort: Montana's American Prairie Reserve. Through qualitative review of web‐based documents and newspaper articles, it generates a preliminary account of key stakeholders' causal stories. The case study suggests that parties who might be disadvantaged by ascribing responsibility for environmental harms in an adversarial fashion may instead elect to articulate causal stories that are more neutral than existing approaches might forecast. The study concludes by suggesting that further development of causal story literature may enable it to better address contemporary conservation efforts. 相似文献

共享经济中形成了"平台+履约人"的新就业模式,催生了一个全新的就业群体——"独立工人"。"独立工人"与平台之间没有传统意义上的劳动关系,仅根据平台要求向客户提供劳务或服务。研究显示:我国共享经济从业人员以"独立工人"为主,吸纳的劳动力主要是受教育程度较低、技术等级较低、外地农业户籍的青壮年男性。在共享经济中有四至五成的从业人员属于专职"独立工人"。研究发现:选择从事兼职独立工作的群体有长期从业的倾向,而选择从事专职独立工作的群体则不希望继续从事独立工作。为进一步规范共享经济发展、保护"独立工人"的合法权益,可以从重新审视"独立工人"的法律身份入手,探索建立适合"独立工人"的"可携式福利"体系,尝试总结具有权威性的共享经济劳动标准,以推动该领域的劳动立法。 相似文献

本文旨在利用内容分析法全面展示中央环保督察这一中国环境治理场域下的最新治理实践。中央环保督察的启动是中央政府对压力型环境治理实践中失衡的央地关系、府际关系和政社关系的主动调适,并试图消解因上述关系失衡可能引致的合法性风险。环保督察的实施一方面实现了环保压力的再传导,并通过引导地方政府的注意力来塑造其对环境治理的长期偏好,另一方面也通过建立督查信息链改善了央地间的信息不对称。但由于环保督察内生于压力型体制,因而其领导、组织和运行的微观机制还无法摆脱对运动式治理的路径依赖,这反映了转型期中国环境治理实践的特点:复杂繁重的环境治理任务呼唤进一步完善以法治化为核心的常规治理,但替代性治理机制的匮乏使中央在短期内仍需借助高规格的环保督察来倒逼地方政府完善常规治理。 相似文献
