典型胶合板燃烧特性的锥形量热仪分析

建筑装饰材料因其美观效果在建筑中应用广泛,但这些材料多为可燃和易燃物质,火灾隐患较大,一旦被点燃会导致火灾的迅速蔓延,同时释放出大量的热量,加速室内轰燃条件的形成。迄今为止,有关建筑装饰材料火灾特性的资料仍十分有限,各种不同类型建筑装饰材料的火灾特性还远没有被完全认识。本文利用锥形量热仪,选择杨木、黑胡桃和沙比例3种不同类型典型胶合板为试验材料,通过横向比较不同材质胶合板的燃烧特性,研究胶合板的密度和热辐射对材料的点燃时间、热释放速率、质量损失速率等参数的影响。通过对试验数据的分析比较,提出了预测以上这些参数的经验公式,通过试验验证了其可靠性,并对其在火灾发生时的危险性大小进行了分析。     

社会结构因素对量刑影响的实证分析以盗窃罪为例的案件社会学研究

刑事审判包括定罪和量刑两个阶段.而量刑正义是刑事正义的最终体现,只有体现于量刑公正、合理的刑事正义才是真正意义上的刑事正义.[1]近年来,刑法学界有关量刑的著述大多以刑法原则为指导,[2]刑法条文为圭臬,鲜有紧密联系司法审判实践之作.为解决这一张力,笔者引入布莱克的案件社会学理论,通过实证分析的方法,考察被告人的年龄、...     

研究进路、理论资源与政治特性——基于市场社会与市民社会的比较分析

基于同一的市场研究进路,但因不同的理论取向与场域,导致两者与国家的关系呈现出亲缘性与对抗性的二元差异,使得两者表现出迥异政治特性。     

证券犯罪主体特征的犯罪学分析

在客观环境基本相同的条件下,为什么只有少数人实施证券犯罪,为什么是这些人而不是其他人实施证券犯罪,这从刑法学犯罪构成的角度是难以回答的。而从犯罪学的视角看,则不难发现证券犯罪的主体在智能结构、需要结构和道德法律意识等方面均具有显著的特征,正是这些特征构成了证券犯罪的主观基础。     

The Effects of Burning and Mold Growth on the Chemical Composition of Firelog Fuels

Firelogs consist of a cellulosic material, such as sawdust or wood particles, and a combustible binder (fuel). Historically, the fuel typically consisted of a petroleum‐based (paraffin) wax; however, some manufacturers now include vegetable oils in their firelog fuels. To determine fuel composition, fuels from various brands of firelogs were extracted and analyzed by high‐temperature gas chromatography–mass spectrometry (HTGC‐MS) and a GC‐MS with a polar column specific for the analysis of fatty acid methyl esters (FAMEs). Firelogs were also burned, allowed to grow mold, and analyzed by GC‐MS to determine the effects that burning and mold growth have on firelog fuel composition. Mold did not tend to preferentially degrade any of the fatty acids. Burning caused a decrease in the relative amount of all of the fatty acids present in the vegetable oil fuel, with a greater effect on unsaturated fatty acids than saturated ones.     

The Control of Police Powers

This article points to a frequent feature in debates about the control of the police. Aside from cultural and political characteristics in the last decades, policing has changed and at present it is going through a stage of rapid change. The author defines the historical roots of police in democracies. He places the police within the framework of the sovereign state, the administration, the judiciary and the citizens. The state's control of police powers is described in its interdependency with new demands on the part of citizens regarding micro (domestic sphere/neighbourhood/community) and macro (urban sphere/state/European) levels. On a European scale, the article provides an oversight over the existing network consisting of internal, administrative, parliamentarian, judiciary, and civil (non-government/social movements) control agencies and mechanisms. In its conclusions the concept of ethical standards is introduced as a means of effective high-quality police management.

公共危机管理的内涵及其特点

公共危机管理就是公共管理机构通过建立危机应对机制,采取一系列必要措施,防范、化解危机,恢复社会秩序,保障人们正常生产和生活的活动,维护社会稳定,促进社会和谐健康发展。公共危机管理是公共管理的一种特殊状态和特殊形式。它在价值目标、控制手段、外部环境以及社会约束等方面与企业危机管理不同。与常规公共管理相比,它具有决策风险大、管理难度大和人员素质要求高的特点。     

判别分析法在鞋底磨损特征检验中的应用

目的从统计学角度论证同一人的鞋底磨损特征具有相对稳定性。方法对50名实验对象（同质人群）的穿鞋足迹中的鞋底磨损特征进行量化测量,并对测量结果用判别分析的方法进行处理。结果不同人的鞋底磨损特征具有差异性,并且可用于不同人的鉴别。为利用鞋底磨损特征进行个人识别提供了理论基础。

The effect of school classroom characteristics on low self-control: A multilevel analysis

Gottfredson and Hirschi's general theory has reaped a substantial amount of empirical support. Recently, attention has focused on the factors associated with the development of self-control. With few and isolated exceptions, most research has examined the ways in which parents contribute to the development of self-control in children. Gottfredson and Hirschi hypothesized, however, that other social institutions, especially schools, may play at least some role in inculcating self-control. The current study addressed this possibility by conducting a series of multilevel models that examined whether the characteristics of schools, and classrooms within schools, were salient to the development of self-control. Using a longitudinal sample of kindergarten and first-grade students, the results revealed that classroom characteristics influenced self-control.     

The prevalence and characteristics of intimate partner violence in a community study of Chinese American women

A community probability-sampled survey was done of 181 Chinese American women to investigate the prevalence and nature of intimate partner violence (IPV) in Chinese Americans. Of participants, 42% knew a Chinese woman who had experienced IPV. Also, 14% had experienced IPV themselves in their lifetime (8% severe and 6% minor), 3% in the previous year, and 2% currently. In Chinese American women who were ever married, the lifetime prevalence of IPV was 17%. IPV resulted in physical injuries for 31% of women and affected their work and education. Exploratory analysis suggests that relationship problems and partner's alcohol use may be risk factors for IPV in this group.
