贝卡里亚之“社会危害”理论探析

贝卡里亚深受启蒙思想家的影响,认为犯罪是对社会契约的违反;同时贝卡里亚为了反对封建社会的思想为罪,提出了＂社会危害＂理论,从而为判断犯罪找到了客观依据。社会危害理论的提出也进一步引证了贝卡里亚的功利主义思想。

贵州省农村中学物理实验骨干教师培训方案设计

根据国家基础教育发展和素质教育对初中物理教师提出的新要求,基于贵州省农村中学物理教师的现状,指出省级农村中学物理实验骨干教师培训的目标和任务,设计了培训模块、培训内容、培训方式、培训教学模式、考核评价办法等,以期在培训中能够着力解决农村中学物理教师在实验教学中遇到的实际问题。     

英语人体部位表达的语法转喻

转喻是普遍的语言现象,更是基本的思维方式。根据抽象程度,转喻可分高层转喻和低层转喻,语法转喻为高层命题转喻。通过对英语人体部位表达的行为代过程和感知代体验事件等高层转喻的研究发现,突出身体部位的功能是该类转喻的基本理据;借助转喻思维,身体部位表达由非转喻用法中的原始位置移位到更优势的主语位置。     

高职院校青年教师激励机制研究——以重庆市高职院校为例

青年教师作为高职院校教师队伍的生力军,正承载着为社会直接培养高素质的应用性技术人才的重任。通过分析青年教师需求特征,提出建立适度倾斜的薪酬制度、创建青年教师个人发展的平台等有效激励机制。     

《诗经》中“水-爱情”模式的生成与表现

水是中国古代文学中重要的审美意象,“水-爱情”的书写模式更是值得关注的。文章以《诗经》中的爱情诗为例,分析了水成为审美意象的成因,并探寻了水与爱情的共通之处。     

人文关怀视阈下的高校思想政治教育

体现人文关怀,既是我国高校学生思想政治教育的一个基本理念,也是高等学府应有的大学精神,更是学生思想政治工作自身内在属性的必然要求。只有这样,才能使学生真正感受到来自学校的温暖和尊重,有利于培养彼此的信任和情感,使思想政治教育在和谐、轻松、对等的氛围中开展下去,保证学生思想政治工作达到预期的效果。     

Tribology Performance and Adhesive Strength Evaluation of TiAlSiN Coating

Scratch test and friction test were performed to evaluate the internal and external interface behaviors of TiAlSiN coating, respectively. The critical compressive and shearing stress of coating failure during scratch test were calculated and the values are 30.84 MPa and 4.98 MPa respectively. The average friction coefficients of TiAlSiN coating against 2Cr12Ni4Mo3VNbN steel are 0.70 (sliding speed 50 m/min), 0.63 (sliding speed 100 m/min), and 0.81 (sliding speed 150 m/min). The elements diffusion was analyzed by EDS. Al and Si element of coating material diffuse to the steel disc, except Ti element. The oxidation decreases with the increase of sliding speed, but the adhesion increases with the increase of sliding speed. More Al element diffuses to the steel disc at the high sliding speed, but the diffusion of Si element keeps almost constant at different sliding speeds.     

Experimental and FEM Study of Coated and Uncoated Tools Used for Dry Milling of Compacted Graphite Cast Iron

Compacted graphite cast iron (CGI) has been the material for high-power diesel engines recently, but its increased strength causes poor machinability. In this study, coated and uncoated carbide tools were used in dry milling experiment and FEM simulation to study the machinability of CGI and wear behaviour of tools. The experimental and FEM simulation results show that coated tool has great advantage in dry milling of CGI. SEM and EDS analysis of tool wear indicate the wear morphology and wear mechanism. Adhesive wear is the main mechanism to cause un-coated tool wear, while abrasive wear and delamination wear are the main mechanism to cause coated tool wear. Stress and temperature distribution in FEM simulation help to understand the wear mechanism including the reason for coating peeled off.     

基于VAR模型通货膨胀影响因素的实证分析

分析了十年我国两次比较严重的通货膨胀的成因,使用2001年1月—2010年9月的季度数据,在构建稳定的VAR模型基础上,通过建立协整方程,运用格兰杰因果检验以及脉冲响应函数的方法,对其进行分析。结果表明：经济增长、广义货币供给量、房地产销售价格指数、外汇储备与CPI之间存在长期的协整关系;长期内以房地产为代表的资产价格对CPI的冲击较大,短期内外汇储备推高CPI的效果最为显著。
