Dermestes maculatus (Coleoptera: Dermestidae) development under fluoxetine effect using two drug administration models

Fluoxetine is a selective serotonin reuptake inhibitor, commonly used for the treatment of a variety of psychopathological conditions. As such, fluoxetine may be expected to appear in clinical and forensic cases. Dermestes maculatus De Geer (Coleoptera: Dermestidae) has been recognized as a relevant component of the insect fauna associated with decomposing human and animal remains. Experiments were conducted to study the effect of fluoxetine on developing D. maculatus using two‐drug administration models: a non‐living animal model (pork muscle) and a living one (Sus scrofa L. pigs). We assessed the duration of immature stages and total life cycle, as well as morphological parameters (body length, cephalic width, and weight). The effect of fluoxetine was studied at an overdose concentration: In the non‐living animal model the drug was mixed with macerated pork muscle (2000 mg/kg) and in the living animal model, pigs were given the drug orally (833 mg/kg). A control was used for each model. Daily observations were performed from the beginning to the end of the experiments. GC‐MS was used for drug detection and quantification. There were no statistically significant differences in the duration of immature stages, life cycle, larval mortality, morphological parameters, or sex ratio, between treatment and control, regardless of the drug administration model. Given that fluoxetine had no detectable effect on the development of D. maculatus, detection of this drug in forensic situations would not compromise the accuracy of PMI estimations.     

论我国职业病防治法律规制的进路及完善

我国已建立多层次保障职业健康和防治职业病的规制体系,其具体进路主要表现为劳动者权益保护日益增强、用人单位责任进一步强化、便捷高效原则更加突出、职业病防治监管主体多次转变。四条进路之间呈现既相互联系又相互区别的辩证统一关系,表明我国职业病防治重点解决职业病诊断、鉴定及追责之困境,已将劳动者权益置于首位,摆脱了法律工具禁锢,而转向权益保障的价值目标。展望未来,尚可从匹配职业病诊断和鉴定机构的管辖级别、设立职业病鉴定中的听证程序、持续推行高效便民原则及实现对职业卫生监管直接责任人员的监察整合等方面进一步优化。     

The Investment Approach to Public Service Provision

The investment approach to public service provision is now receiving considerable attention worldwide. By promoting data‐intensive assessments of baseline conditions and how government action can improve on them, the approach holds the potential to transform policy development, service implementation, and program evaluation. Recently, variations on the investment approach have been applied in Australia to explore the effectiveness of specific programs in employment training, criminal justice, and infrastructure development. This article reviews the investment approach, presents a Public Investment Checklist to guide such work, and discusses three examples. It concludes by considering the implications of investment thinking for the work of policy designers and public managers.     

The origins of severance pay in unemployment compensation: a comparative analysis

ABSTRACT

This article contributes to an under-developed field in the social policy literature through an analysis of the origins of severance pay (SP)/redundancy pay schemes and, more specifically, their first designs in nine countries—Canada, the United Kingdom, Germany, Austria, France, Italy, Sweden, Spain, and Portugal. It has two objectives: first, to identify the key actors who shaped the design of the first SP schemes; second, to explain variations in terms of their mode of regulation, generosity and coverage. By building on the state-centric and power-resource perspectives, it identifies the conditions under which the state had an autonomous role vis-à-vis organized labour in SP reforms and the circumstances under which organized labour was the main actor. When the state was the key actor, it preferred legislation for the regulation of SP either to legitimize its apparatus in a ‘revolutionary’/‘potentially revolutionary’ context or to facilitate structural transformations of the economy in a ‘reformist’ context. When organized labour was the key actor, its preference was to regulate SP through ‘only collective bargaining’ or ‘legislation’, subject to the degree of unionization. Lastly, the paper argues that key actors (the state or organized labour) took into account the distributive structure of existing UI schemes when designing the coverage and generosity structure of the first SP schemes during the post-war era.     

语块教学与提高英语口语能力的实证研究

语块作为自然话语的重要组成成分,可以促进语言输出自动化。因此,教师应把语块作为大学英语口语教学的基础单位和资源库,鼓励学生通过存储和调取大脑中的语块来提升英语口头表达能力和实际应用能力。     

如何认识当前的国际经济危机——兼评外国学者的各种见解

当前仍在持续的国际性经济危机,本质上是资本主义生产方式的危机。这次危机不仅使传统资本主义模式难以为继,也宣告了新自由资本主义的破产。但资本主义制度不会就此退出历史舞台,而是将在资本主义制度范围内通过深刻的变革而实现模式转型。中国作为新兴的市场经济大国,已经不可避免地处于国际性的经济危机之中了,其内因是基本的。为此,必须深刻总结30多年来改革发展的经验教训,适当转变改革思路和发展方式,走一条既符合一般规律又符合中国国情的发展道路。     

东兴国家重点沿边开发开放试验区先行先试政策体系研究

设立东兴国家重点开发开放试验区,提升沿边开放开发水平,是服务国家"睦邻安邻富邻"的外交战略需要;是实现兴边富民,全面建设小康社会的战略选择;是打造广西北部湾经济区增长新高地的重大举措。构建东兴试验区先行先试的政策支撑体系,增强其自我发展能力,保障和改善民生,是加快建设东兴开发开放试验区的题中之义。     

在经验与规范之间:试验立法及其类型化——一种立法进路的提倡

立法理想与法律运行实践间背离的中国境遇,以文本法律不完全是"能用之法",且立法承诺在执法中不能全部兑现之困局为现实表征。以进化论理性主义的哲学立场和无知论的知识假设为理论支撑,采取反复试错、吸纳建议、对话商谈等自发性工具,将实践证明可行的执法经验提炼与抽象,进而升华为普遍性规则的试验立法进路,是修正建构论唯理主义立法进路并撬动当前格局的一个支点。试验立法进路以"采纳—辐射"这个简式架构为运作逻辑。目前的试验立法主要有尝试探索型试验立法、落实测试型试验立法与示范效仿型试验立法三种模式。试验立法的实践性意味着多数立法活动将建立在证据或实证研究的基础上,也将具有方法论的意义,有望成为我国立法方法法定化的发展方向。     

“粤港澳大湾区”三地制度建设路径探索

2019年中央颁布《粤港澳大湾区发展规划纲要》,将粤港澳大湾区计划初步建设成为世界一流湾区。改革开放以来,广东与港澳的关系一直非常紧密,尤其在经贸合作领域,香港和广东的关系犹如“前店后厂”。与长三角、京津冀地区实践不同,粤港澳大湾区是“一国两制”下的一次重大探索式发展。粤港澳大湾区有其特殊地位,粤港澳三地三种不同的关税区具有不同的制度和法律,应在维护“一国两制”的前提下探索三地的深度融合。     

Who is a Terrorist? Ethnicity,Group Affiliation,and Understandings of Political Violence

What does the American public label as “terrorism?” How do people think about the factors motivating violence, and in turn, the policies that are favored? Using ingroup and outgroup dynamics, we argue that the terrorist label is more readily applied to Arab-Americans than Whites, and to members of militant groups. Moreover, people attribute different motives to violence committed by Arabs versus Whites, and favor different policies in response. We conducted an experiment where we randomly assigned one of six stories about a failed armed attack, each with a different combination of ethnicity and group affiliation. We find that an Arab ethnicity and Islamist group affiliation increase the likelihood of labeling an act as terrorism. Attacks by Whites and members of a White supremacist group are less likely to be labeled terrorism. Rather, Whites are more likely to be called “mass shooters.” Despite never discussing motive, Arab-American attackers are more likely to be ascribed political or religious motives, while White suspects are more likely to be seen as mentally ill. Lastly, an Arab ethnicity increases support for counterterrorism policies and decreases support for mental health care.
