Trajectory Reconstruction Through Analysis of Trace Evidence in Bullet–Intermediate Target Interaction by SEM/EDX

Abstract:  A young male was shot to death by a police officer with a Chinese Type 64 7.62 mm pistol when he was dealing with an aggravated assault arising from a traffic accident. By using scanning electron microscopy and energy dispersive X-ray spectroscopy (SEM/EDX), trace deposits on the discharged bullet and the intermediate target, i.e., a concrete telegraph pole at the scene, were identified to be from each other. The result demonstrated the bullet causing the death ricocheted from the concrete telegraph pole before striking the victim, thus indicating the incident was accidental. The case report illustrates the evidential value of trace materials derived, respectively, from discharged bullets and intermediate targets in bullet–intermediate target interaction for trajectory reconstruction. In addition, it indicates that the SEM/EDX method with its nondestructive nature, compared to other methods, may be more helpful in certain situations in determining the origins of trace evidentially valuable deposits on substrates.     

论行政体制改革与宪政的互动

行政体制改革与宪政的互动是二者关系的实质体现,它一方面要求宪政必须为行政体制改革的启动和展开提供基本框架,进而指引和规范行政体制改革;另一方面,行政体制改革也必须张扬宪政的价值诉求,实践宪政的制度安排,从而促进宪政的发展与完善.两者的相得益彰需要经济体制、政治体制、社会体制、财政体制的配套改革以形成整体合力支撑.     

市场调节与政府管制之联系与互动的思考——解决就业歧视问题中的经济法路径分析

经济法是伴随国家（政府）对社会经济生活适度干预而形成的法律部门。经济法体现着公私法相融合、国家渗透市场等理念,自其诞生之日起,便与国家和市场有着紧密的关系。经济法也正是基于市场失灵与政府缺陷的两重原因,确立了自己调整社会经济关系的逻辑基点和路径选择。现今社会中劳动力市场就业歧视的问题也正体现了市场调节失灵和政府管制缺陷的两难境地。如何反对就业歧视应得到经济法的关注,运用现代经济法的“市场调节（失灵）——政府管制（缺陷）”路径对其进行分析具有十分重要的理论价值和现实意义。     

Private authority and public policy interactions in global context: Governance spheres for problem solving

Private organizations play a growing role in governing global issues alongside traditional public actors such as states, international organizations, and subnational governments. What do we know about how private authority and public policy interact? What are the implications of answering this question for understanding support for, and effects of, policy development generally? The purpose of this article is to reflect on these questions by introducing, and reviewing, a special issue that challenges explicit claims, and implicit methodologies, that treat private and public governance realms as distinct and/or static. We do so by advancing a theoretical and conceptual framework with which to explore how the contributions to this special issue enhance an understanding about governance interactions across a range of empirical, sectoral, and regional domains. We specifically introduce the concept of governance spheres to capture the proliferation of issue domains denoted by highly fluid interactions across public and private governance boundaries.     

Disaggregating public-private governance interactions: European Union interventions in transnational private sustainability governance

Transnational private sustainability governance, such as eco-certification, does not operate in a regulatory or jurisdictional vacuum. A public authority may intervene in private governance for various reasons, including to improve private governance's efficient functioning or to assert public regulatory primacy. This article argues that to properly understand the nature of public-private governance interactions—whether more competitive or complementary—we need to disaggregate a public authority's intervention. The article distinguishes between four features of private governance in which a public authority can intervene: standard setting, procedural aspects, supply chain signaling, and compliance incentives. Using the cases of the European Union's policies on organic agriculture and biofuels production, the article shows that public-private governance interaction dynamics vary across these private governance features as well as over time. Furthermore, the analysis highlights the importance of active lobbying by private governance actors in influencing these dynamics and the resulting policy outputs.     

亚太大国“伙伴关系”的互动性和不对称性

冷战后亚太中美俄日四大国为了在未来世界多极格局中取得有利位置,纷纷建立各种形式的伙伴关系,四大国之间伙伴关系的建立、固然有其国家利益基础,但也有大国关系互动的影响。由于各种伙伴关系建立的利益基础和所要实现的战略目标的差异,四大国之间建立的六对伙伴关系是不对称的,这种不对称既体现出目前伙伴关系发展的不成熟,也表明亚太大国之间存在严重分岐与障碍,并有可能影响亚太局势的稳定发展。

互联网时代“00后”大学生社会心态建设研究

多元文化交融的互联网时代,形塑了多元的社会心态。当代高校为了更好地贯彻落实“立德树人”的教育方针,大学生的社会心态建设是思想政治教育中的重要问题。“00后”大学生作为“数字原生代”,需要教育工作者在互联网时代找到他们存在的地方,厘清影响其价值观和心态的多元文化,和他们一起建构能够顺应时代要求的生活和价值,建设有利于社会发展的社会心态。思想政治教育工作者要以肯定引导、去标签化、多主体参与为导向,加强网络思想政治教育工作,以更好地与“00”后大学生实现同频共振。     

家庭教养方式研究进程透视

家庭教养方式是儿童社会化的重要因素，受到国内外心理学家的重视。该文综述了中外心理学家在儿童社会化研究中对家庭教养方式研究的成果，概括了近20年来，中国学者在家庭教养方式研究中呈现的诸如教养方式与儿童社会关系的探讨从宏观系统走向微观、具体，进一步探究教养方式的内在结构，尝试从更多方面寻找教养方式的影响因素等特点。家庭教养方式研究成果的取得，受到三方面因素的推动，首先，它与人类对自身探究的好奇心分不开。其次，它与儿童发展观念及理论的进展所产生的影响分不开。再次，它与心理学研究的现场化，研究手段的综合化、数学化所带来的影响分不开。     

农民工返乡创业与乡村振兴战略的耦合互动机制及其助推路径分析

党的十九大开启了乡村振兴的新篇章,标志着农村的改革和发展又进入了一个新阶段。而农民工是乡村振兴的助推器,是解决当前我国社会矛盾的重要抓手。一方面我国乡村振兴面临着人才缺失、农民主体性缺失、乡村治理无序、资金短缺等多重困境;另一方面乡村振兴战略的提出为农民工返乡创业提供了项目和平台,其政策红利吸引着农民工进行返乡创业;同时,农民工返乡创业又能及时弥补乡村人才缺口,促进乡村地区产业转型升级,为乡村振兴注入资金保障,并能够改善乡村社会治理。因此,可以通过实施差异化的农民工返乡创业引导策略,构建多维度的农民工返乡创业政策环境,开展针对性的农民工返乡创业培训支持等途径来助推乡村振兴的实现。
