从方法论角度看中国美学的研究现状

从方法论的角度看,中国美学从建国到现在正沿着一条肯定———否定———否定之否定的辩证道路前行。其间,我们的美学研究接受着来自各方的影响,既表现了自己的特色,也暴露出了一些问题。我们应在立足马克思主义美学的基础上,融汇东西,建立具有中国特色的美学。     

在格斗教学中培养学员的创新能力

格斗教学是公安院校教学内容的重要组成部分。在教学中应该注重加强学员创新能力的培养 ,给学员创造自由展示的课堂空间 ;给学员自由提问的主动权 ;给学员自由选择的权力 ;给教师创造提高自身素质的机会。运用发现引导法、创造性教学法和合作讨论法等教学方法 ,培养和提高学员的创新能力 ,使格斗教学取得良好的教学效果。     

我国法定抵押权制度的若干立法构想

法定抵押权制度源于古罗马法,在近现代民法法典化的过程中,由于社会背景和知识谱系的差异,分化为以德国、日本和瑞士为代表的三种立法体例。文章围绕法定抵押权的基础及类型化、公示方法的设计和优先次序的安排等问题,分析和比较了其他国家和地区的立法,系统地阐释了法定抵押权制度的相关理论,试探性地提出了构建我国法定抵押权制度的若干立法建议。     

中国古代早期文明研究的思考

中国古代早期文明的研究亟需跳出固有的传统窠臼 ,扩大视野 ,转变思路 ;对现存有限的文献资料和历史传说也必须以新的方法 ,作综合分析和比较研究 ;对具有丰富潜力的地下考古新成果更需及时吸收运用 ,开辟新的资料来源 ,从而使我们的研究工作取得重大突破 ,更健康深入地开展下去     

强奸犯类型研究及其在侦查中的应用

强奸犯罪严重侵犯公民人身权利且犯罪黑数极高,加强其侦查研究十分必要。国外学者对强奸犯类型有详细的研究,按照美国联邦调查局行为科学组的强奸犯分类对各类型的人格特质和犯罪过程特点可作深入剖析,并在此基础上析出有关的侦查对策。通过理论的借鉴,以期对强奸案件侦查研究与实务有所助益。     

论我国刑事责任的承担方式

刑事责任问题是刑法理论中比较重要的问题.正确认识刑事责任的承担方式是刑法发展的要求,同时也是 刑事责任理论应用于实战的前提条件。本文探讨了我国刑事责任的承担方式,并提出刑事制裁概念。     

犯罪现场勘查若干理论问题探析

Comparative Politics and the Synthetic Control Method

In recent years, a widespread consensus has emerged about the necessity of establishing bridges between quantitative and qualitative approaches to empirical research in political science. In this article, we discuss the use of the synthetic control method as a way to bridge the quantitative/qualitative divide in comparative politics. The synthetic control method provides a systematic way to choose comparison units in comparative case studies. This systematization opens the door to precise quantitative inference in small‐sample comparative studies, without precluding the application of qualitative approaches. Borrowing the expression from Sidney Tarrow, the synthetic control method allows researchers to put “qualitative flesh on quantitative bones.” We illustrate the main ideas behind the synthetic control method by estimating the economic impact of the 1990 German reunification on West Germany.     

A Simple Digestion Method with a Lefort Aqua Regia Solution for Diatom Extraction

Presence of diatoms in tissues has been considered as a significant sign of drowning. However, there are limitations in the present extraction methods. We developed a new digestion method using the Lefort aqua regia solution (3:1 nitric acid to hydrochloric acid) for diatom extraction and evaluated the digestive capability, diatom destruction, and diatoms' recovery of this new method. The kidney tissues from rabbit mixed with water rich in diatoms were treated by the Lefort aqua regia digestion method (n = 10) and the conventional acid digestion method (n = 10). The results showed that the digestive capability of Lefort aqua regia digestion method was superior to conventional acid digestion method (p < 0.01); the structure of diatom remained almost intact; and the recovery of diatom was comparable to the conventional acid digestion method (p > 0.05). The Lefort aqua regia reagent is an improvement over the conventional acid digestion for recovery of diatoms from tissue samples.     

Investigating the Potential of Fluorescent Fingerprint Powders as a Marker for Blow Fly Larvae (Diptera: Calliphoridae)

Four fluorescent fingerprint powders (RedWop^?, GreenWop^?, Basic Yellow^?, and Yellow Powder^?) were evaluated as a marker for blow fly larvae. Administration methods included ingestion (high vs. low concentration) or topical. Ingestion of high concentrations of Basic Yellow^? and RedWop^? caused higher larval mortality. Basic Yellow^? delayed development and adult emergence while RedWop^? and Yellow Powder^? had a significant effect on particular stages of development, however, emergence time was not altered. Optimal administration is through ingestion at low concentration levels (<10%) or topically, with GreenWop^? demonstrating minimal adverse effects. Optimum wavelength for discrimination between powders was 450 nm. This research can aid in investigative training to increase visibility of larval and pupal blow flies. It can also be used in entomological studies to differentiate between larval blow flies (or other dipteran) species or individuals to further understand complex interactions and behavior during larval development.
