An initial evaluation of stable isotopic characterisation of post-blast plastic debris from improvised explosive devices

A number of two-way radios, similar to those which have been employed to initiate Improvised Explosive Devices (IEDs), were acquired from a commercial supplier and grouped into four pairs. Samples of plastic material were collected from five distinct regions of each radio and analysed by Infrared and Raman spectroscopy to identify the nature of the material. One radio of each pair was then subjected to detonation with a commercially available plastic explosive. The combination of radio and explosive was considered to be representative of the components of an IED. Following detonation, fragments were recovered and, where possible, identified as specific sampling points of the radio.A combination of δ²H and δ¹³C stable isotopic analysis of material from each of the five sampling points was found to provide a pattern which was characteristic of a given radio and provided a means to associate pairs of radios. When few fragments were recovered, no positive association could be made between the fragments and the paired, undamaged radio. This was attributed, in part, to manufacturing variation in the radios. However, when three or more post-blast fragments were recovered it was possible to associate these with the paired, undamaged radio with a high degree of certainty.

近年来,全国一些地方相继发生突发群体性事件,引起社会各界的广泛关注。在当前严峻复杂的社会稳定形势下,亟待抓紧研究建立应对处置突发群体性事件的应急管理机制。针对突发群体性事件的发展状况,指出当前国内突发群体性事件的一些主要特点。从政治学角度,深入探究突发群体性事件的肇因,为从根本上预防和减少群体性矛盾提供有益的启示。从预防与应急准备、实时监测与预警、应急处置与救援、事后恢复与重建等四个方面,提出应对处置突发群体性事件的工作制度,以规范处置行为,提高处置能力,维护社会稳定大局。     

西方政治参与研究述要

西方政治参与理论的研究内容主要集中在政治参与的历史脉络、政治参与的作用、政治参与的方式、途径与政治参与程度、政治参与与政治稳定的关系等方面。关注西方政治参与理论,可以为发展中国特色的政治参与理论提供一定的参考和借鉴。     

论《公司法》对职工参与公司治理制度的法律规定

新修改的《公司法》在相关理论和实践发展的基础上,突破了股东治理结构的局限性,改变了职工民主权利从属于资本的划分标准,规定了在所有的公司制企业都实行以职工代表大会为基本形式的民主管理。明确规定公司的职工董事和职工监事制度,极大地推进了职工参与公司治理制度的深化和规范化。     

Can Audience Development Promote Social Diversity in German Public Arts Institutions?

Despite generous public funding, arts institutions in Germany are primarily serving a small, educated section of the German population. This article presents findings from arts participation surveys, research from an empirical study on “Intercultural Audience Development” in public theaters and museums, and an analysis of cultural policy debates to reveal the role of audience development in overcoming the social imbalance of audiences in German cultural institutions. Research findings suggest that traditional concepts of audience development do not lead to sustainable changes in the social structure of the audience. More substantial institutional changes are necessary, supported by new cultural policies.     

Contradictions in Participatory Public Art: Placemaking as an Instrument of Urban Cultural Policy

This article addresses the current focus within urban cultural policy on using art as a tool in urban development. Based on theories of participation, democracy, and public art, the article sets out to investigate critically the concept of placemaking. The discussion is based on an analysis of the public art project Placemaking, which took place during 2015 in eight municipalities around Copenhagen in Denmark. I argue that, when used as a tool in urban development, participatory public art engenders contradictory encounters. These encounters challenge the cultural political effort to democratize art and culture.     

Simultaneous Determination of 13 Anticoagulant Rodenticidesin Human Blood by Liquid Chromatography–Tandem Mass Spectrometry and its Application in Three Poisoning Cases

Anticoagulant rodenticides are widely used for rodent control around the world. A rapid and sensitive method was developed and validated for the simultaneous determination of 13 anticoagulant rodenticides (coumafuryl, pindone, valone, warfarin, coumatetralyl, coumachlor, diphacinone, dicumarol, chlorophacinone, bromadiolone, difenacoum, flocoumafen, and brodifacoum) in human blood by liquid chromatography–tandem mass spectrometry. After liquid–liquid extraction, the anticoagulant rodenticides were separated on an Eclipse Plus C18 column. Linearities were observed for each analyte in blood ranging from 0.5 to 50 ng/mL, with correlation coefficients over 0.99. The limits of detection ranged from 0.01 to 0.2 ng/mL, and the limits of quantification were 0.5 ng/mL for all analytes. The intraday and interday precisions were <15%, and accuracies ranged from 80.3% to 111.0%. This validated method with high sensitivity has been applied in three anticoagulant rodenticide poisoning cases and has been used successfully in monitoring blood concentrations for months.     

著作权延伸性集体管理制度的中国化构建——以比较法为视角

源于北欧诸国著作权法上的著作权延伸性集体管理,将本由集体管理组织与使用者之间的作品使用合同依法延伸适用于非会员权利人。因该制度涵盖面广、可降低交易成本等显著特点,目前已成为世界各国解决数字化环境下作品海量使用授权问题的首选立法方案。我国《著作权法修订草案(送审稿)》引入了此项制度,但颇具争议。引入著作权延伸性集体管理制度符合我国国情,但需谨慎移植,删除《著作权法修订草案(送审稿)》第63条"其他方式"的表述,增加集体管理组织的通知义务;在第74条中增加,在非会员权利人起诉使用人侵权,法院判决使用人支付赔偿时,"集体管理组织应向使用人退还所收取的使用费"。     

A voice or a choice? Children’s views on participating in decisions about post-separation contact with domestically abusive fathers

ABSTRACT

The United Nations Convention on the Rights of the Child explicitly calls for children to be granted the right to participate in legal proceedings that affect them. Despite this legal obligation and an evolving consensus that recognises children as social and competent actors, this rhetoric has struggled to achieve translation into meaningful practice reality, particularly when decisions are being made about contact arrangements for children where there has been a prior history of domestic violence. Drawing on the narratives of children who participated in three separate research projects in Ireland between 2009 and 2015, this paper will consider the manner in which they were involved in the decision-making process and the extent to which their views were ascertained and their voices heard. This paper concludes by raising the key question of how the child’s best interests can be served if the child’s views are not sought, heard or considered.     

Accuracy and Reliability of Total Body Mass Estimation Techniques from Stature and Bi‐iliac Breadth in Non‐Hispanic U.S. Whites from the Bass Donated Skeletal Collection

This paper tests the fidelity of a recent method that used the NHANES III dataset as a proxy to estimate total body mass from stature and bi‐iliac breadth in U.S. White males and females. The bi‐iliac breadths of 230 males and 152 females identified as non‐Hispanic U.S. White from the Bass Donated Skeletal Collection were measured, and along with stature from predonor paperwork, total body mass estimates were calculated and then compared to body masses recorded on predonor paperwork. Male and female samples were subdivided by body mass index (BMI [kg/m²]) categories established by the World Health Organization. Our results suggest that total body mass estimates can be accurately assessed provided that the individual is within 18.50 ≤ BMI ≤ 29.99 for White males and 18.50 ≤ BMI ≤ 24.99 for White females. Recommendations on how to report total body mass estimates are also presented.
