This population study was conducted to assess the frequency of physical, microscopical, and chemical properties of automotive paint chips. Population studies of trace evidence provide valuable analytical data for criminalists to assess evidentiary significance. Two‐hundred automotive paint chips were collected from auto body shops from the Northeastern United States. All samples were analyzed using stereomicroscopy, brightfield, and polarized light microscopy. Red paints were targeted for further analysis using a sequence of modern instrumental techniques commonly used by forensic paint examiners: Fourier‐transform infrared (FT‐IR), Raman, and ultraviolet–visible (UV–Vis) microspectroscopy. The discrimination potential of each analytical method was evaluated by inter‐comparing the paint samples. Results demonstrated that macroscopic and microscopic properties were able to differentiate 99.995% of the population (one undifferentiated pair out of 19,900). When combined with either FT‐IR or UV–Vis microspectroscopy, all paints were differentiated. The results of this research lead to the conclusion that one would not expect to encounter two indistinguishable paint chips originating from different sources during the investigation of a single event.  相似文献

This article discusses two inter-related issues. Firstly, the factors lying behind Russia's fervent belief that its Novorossiya (New Russia) project, aimed to bring back to Russia eight oblasts of Donetsk, Luhansk, Kharkiv, Dnipro, Zaporizhhya, Odesa, Mykolayiv, and Kherson in eastern and southern Ukraine and launched during the 2014 “Russian Spring,” would be successful. Russian identity misunderstood, and continues to misunderstand, Ukraine and Ukrainians through stereotypes and myths of Ukraine as an “artificial state” and Ukraine's Russian speakers as “fraternal brothers” and Russians and Ukrainians as “one people” (odin narod). Secondly, why Ukrainian national identity was different than these Russian stereotypes and myths and how this led to the failure of the Novorossiya project. Russian stereotypes and myths of Ukraine and Ukrainians came face to face with the reality of Russian-speaking Ukrainian patriotism and their low support for the Russkij Mir (Russian World). The article compares Russian stereotypes and myths of Ukraine and Ukrainians with how Ukrainians see themselves to explain the roots of the 2014 crisis, “Russian Spring,” and failure of Russian President Vladimir Putin's Novorossiya project.  相似文献

随着网络及相关技术的不断发展,构建有序的网络民主参与路径,成为社会主义政治文明建设和国家治理现代化的重要方面。文章论述了网络民主参与具有提高公众参与国家事务积极性、提高网民政治素养和道德觉悟、推动国家治理体系和治理能力现代化等伦理意义。讨论了当前网络民主参与存在少数网民网络民主参与的理性不足、在一些舆情发展过程中缺乏有效地舆论引导能力等问题,并认为网络政治伦理体系建设的滞后等是导致各种问题的主要原因之一。提出培育网民公共理性,加强和完善舆论引导能力,特别是构建具有中国特色的网络政治伦理体系,可从根本上解决网络民主参与的诸多问题,筑造网络民主参与的有效路径,推进国家治理现代化。  相似文献

One of the most problematic aspect of p‐values is the tendency to dichotomize, whereby statistical significance is equated with scientifically worthwhile and insignificance with worthless findings. This article outlines two approaches that move beyond such dichotomies: minimum Bayes factors and the analysis of credibility. Their use is illustrated through a simple example. The examples show that significant findings may not always be as telling as statistical significance would suggest, whereas non‐significant findings may contain considerable evidence about effects.  相似文献

This paper provides a selective survey of food regimes and food regime analysis since the seminal article by Harriet Friedmann and Philip McMichael in 1989, and further traced through their subsequent (individual) work. It identifies eight key elements or dimensions of food regime analysis, namely the international state system; international divisions of labour and patterns of trade; the ‘rules’ and discursive (ideological) legitimations of different food regimes; relations between agriculture and industry, including technical and environmental change in farming; dominant forms of capital and their modalities of accumulation; social forces (other than capitals and states); the tensions and contradictions of specific food regimes; and transitions between food regimes. These are used to summarise three food regimes in the history of world capitalism to date: a first regime from 1870 to 1914, a second regime from 1945 to 1973, and a third corporate food regime from the 1980s proposed by McMichael within the period of neoliberal globalisation. Questions of theory, method and evidence are noted in the course of the exposition and pulled together in a final section which criticises the ‘peasant turn’ of the ‘corporate food regime’ and the analytical and empirical weaknesses associated with it.  相似文献

帕慕克以创作闻名世界,而其文学思想尤其是有关\"文学与政治\"的论述独树一帜,迄今尚未引起学界重视。本文参照其创作实践,并将相关论述与当代西方文论进行广泛比较发现:首先,帕慕克将\"文学与政治\"问题作出解说;其次,他提出另一种文学的政治性,并讨论了非西方的压迫社会的文学与政治的悖论关系,提醒人们文学批评与研究不能忽视文学作品的虚构性此一重要特点;最后,他重新定义\"文学与政治\"的关系,尽力创设一种超越文学与政治二元对立框架的阅读文学的方法框架,加深我们对殖民与后殖民文学的理解和研究。  相似文献

This article presents an analysis of works by Francisco Goldman and Jennifer Harbury, which deal with “cataclysmic moments” of recent Guatemalan history. It explores gender relations in these works with reference to three themes: storytelling, communication and affective relationships. Conceptually, I draw on the notions of decolonial love, the coloniality of gender, and the world gender order as categories of analysis. I take Chela Sandoval's methodology of the oppressed as a guideline for my analysis, and look at the ways in which different types of storytelling perpetuate or question the coloniality of gender, at the consequences of intercultural misunderstandings produced by different readings of the coloniality of gender and the world gender order, and at the significance of a critical and liberatory practice of gender roles for decolonial love. The practice of decolonial love is an alternative to what Tzvetan Todorov has called “the dreadful concatenation,” which is a result of cultural encounters during the conquest of the Americas and which conceptualizes as “love” a feeling that sidesteps equality, an exercise in destruction and possession. The coloniality of gender and decolonial love are explored through their interactions with masculinities and femininities across the different case studies.  相似文献

2021年1月22日起生效的《禁止核武器条约》致力于在全球范围内禁止核武器的拥有、研发、储存、转移、试验、使用或是威胁使用等行为,从而将核武器完全非法化。尽管《禁止核武器条约》反映了人道主义的关怀和无核世界的愿景,但该条约无论是在理论层面还是在现实层面都面临着不小的困境。从理论上看,《禁止核武器条约》以确立禁核规范来推动国际社会所有成员国弃核的逻辑基础并不牢固,因为规范可能退化甚至被颠覆,未必能够对国家产生强有力的约束。在现实层面,《禁止核武器条约》则因为全盘否定核威慑的重要性而遭到拥有核武器国家及其盟国的联合抵制,并暴露出该条约忽视部分国家的安全关切、损害国家自卫权利以及忽略裁军核查机制等不足。鉴于国际社会围绕《禁止核武器条约》产生了诸多争议,未来,该条约还是应当落脚到分步骤、渐进式的核裁军路线上来,需要在提供安全保证、区分禁核情形、建立核查机构,以及加强与不扩散国际机制兼容等方面进行完善,以促进当前核不扩散国际机制的改革和推动陷入停滞的核裁军进程的持续进行。  相似文献

论意义世界   总被引:2,自引:0,他引:2  
意义世界,是支撑人在现实世界中安身立命、生活实践的价值理念系统,是一个超越性的形而上的世界.意义世界是由解释、应当、信仰等多个维度的内容构成的完整的世界,对意义世界的认知应切忌步入"盲人摸象"的误区.意义世界为人之为人、社会之为社会所必需,因而是无法排除的.意义世界是文化建构的结晶,并蕴涵在各种文化形式之中.意义世界避免花果飘零以致一片荒芜的根本奥秘在于与时俱进.  相似文献
