小学语文课外阅读中协同知识建构的特征研究

小学阶段是培养学生阅读兴趣的重要阶段,这一阶段应该以多种形式开展课外阅读以培养学生的阅读素养。知识建构在培养学生语言能力、审美、鉴赏、创造思维、文化传承与理解方面发挥着重要的作用,在小学语文课外阅读中有广泛的应用空间。研究以小学五年级所开展的课外阅读为例,对学生在课外阅读中协同知识建构过程进行了分析,发现课外阅读过程中的协同知识建构具有过程性、自发性、可持续发展性的特征,对培养学生的口语表达能力、审美能力、创作能力和人际交往能力有积极的作用。     

电子探针在电气火灾物证技术鉴定中的应用

在介绍电子探针分析技术的功能和特点的基础上,结合火灾案例说明了电子探针技术在导线熔痕电子显微形貌观察及熔痕微孔表层成分分析中的应用.通过分析,从导线短路熔痕的微观形貌、熔痕孔洞表层的特征元素含量中获得其熔痕形成原因,进而为火灾调查提供技术支持.     

刑事法律制度差异对海峡两岸合作打击跨境犯罪的影响及对策研究

大陆地区和台湾地区的刑事法律制度存在较大差异,必将影响海峡两岸共同合作打击跨境犯罪工作的开展。海峡两岸应在《海峡两岸共同打击犯罪及司法互助协议》框架下,在协商互信的基础上,本着对两岸刑事法律制度差异的清晰认识,采取合理、有效的刑事对策弱化其对两岸合作打击跨境犯罪的影响。     

新形势下警卫部队训练工作探讨

部队战斗力的生成和提高主要依靠平时的军事训练来实现。根据公安警卫部队当前任务实际,着眼新形势下的警卫任务执勤需要,就警卫部队训练对象的层级划分和具体训练目标、训练科目和内容、训练管理体制的建立与完善等问题进行探讨。     

扫描电镜分析法在电动自行车火灾成因鉴定中的应用

由电动自行车引发的火灾中,电动自行车起火原因的调查是非常重要的。由于电动自行车采用各种直流电池作为电源,因而与交流电条件下的各种电气火灾调查鉴定有所不同。在直流电源条件下多股铜导线的短路熔痕的形态特征与普通交流电条件下形成短路熔痕的形态特征存在一定的差异。运用扫描电子显微镜,通过对多股铜导线在直流电条件下一次短路熔痕,过载熔断时所形成的熔断表面及熔珠进行分析研究。通过微观形态的观察,可以区分一次短路或过载熔断。     

我国青少年亲社会行为培养研究

青少年亲社会行为培养关涉一个民族、国家的未来和兴衰.青少年亲社会行为的深层次价值体现,乃是青少年对民族、国家的认同意识、忧患意识和担当意识的自觉与觉醒.对于青少年的亲社会行为培养,主要以坚持社会主义核心价值观为思想前提;以因循传统“知行合一”理论为培养的基本原则;以面向现实人生为培养的关键和落脚点,共同构建青少年的亲社会行为培养模式。     

Does Intent equal Capability? Al-Qaeda and Weapons of Mass Destruction

The prospect of terrorists deploying weapons of mass destruction (WMD) is often referred to as the foremost danger to American national security. This danger has become more realistic because of al-Qaeda's expanding global network and the expressed willingness to kill thousands of civilians. In the past four years, numerous media reports have documented the group's ongoing quest for WMD capabilities; many reports have detailed al-Qaeda members’ attempts to manufacture or obtain certain chemical, biological, radiological, and nuclear (CBRN) agents to use in WMD against targets in the West and the Middle East. Yet the question remains: Does al-Qaeda's current WMD capability match its actual intent? While most studies of the group have focused on its explicit desire for WMD, allegations of CBRN acquisition, and the killing potential of specific CBRN agents, few open-source studies have closely examined the evolution of al-Qaeda's consideration of WMD and, most notably, the merit of actual CBRN production instructions as depicted and disseminated in the group's own literature and manuals. The following report will examine the history of al-Qaeda's interest in CBRN agents, the evolution of the network's attitude toward these weapons, and the internal debate within the organization concerning acquisition and use of WMD. More so, the following research will assess the validity of actual CBRN production instructions and capabilities as displayed and disseminated in al-Qaeda's own literature and websites.     

装备保障抽组力量物资装载模型

对装备保障抽组力量的物资装载问题进行了数学描述,建立了以实现全部物资尽量分散装载为目标,以同类物资集中装载、车辆承载物资总体积不超过车辆有效容积、车辆承载物资总重量不超过车辆标记载重量、物资必须装载且不被重复装载等为主要约束的数学模型,并进行了求解.最后通过实例解算验证了模型的有效性.     

高层建筑安全疏散设计探析

近年来我国高层建筑剧增,承载的人口越来越密集,火灾荷载越来越大,如果安全疏散设计不合理,一旦发生火灾,容易造成严重后果.在分析高层建筑的火灾特点和影响人员安全疏散的因素的基础上,从合理设置安全出口、疏散走道、疏散楼梯、疏散宽度和距离、疏散门、避难层及其他辅助疏散设施、疏散照明灯具等方面探析了高层建筑的安全疏散设计,为避免和减少人员伤亡和财产损失创造条件.     

An Imperfect Jewel: Military Theory and the Military Profession

This article explores a perennial theme in the literature of strategic studies: the relationship between military theory and the military profession. It begins with a conceptual analysis of this relationship. It then investigates what military theorists themselves have had to say about the utility of their craft. It concludes by assessing the actual influence of military theory on selected individuals and institutions. The individuals are George S. Patton, Jr., and Ulysses S. Grant. The institutions are the United States Army and the United States Air Force in the late twentieth century. The fundamental finding is suggested in the title: military theory can indeed be quite useful in the maturation of military commanders and in the development of martial institutions, but it is not always necessary and by no means perfect. It should thus be studied assiduously but used with caution.
