Reducing out-of-home placements of abused children: two controlled field studies

This study presents the outcome data on the effectiveness of social learning treatments in reducing out-of-home placements of abused children. Noteworthy are that true experimental designs used in both studies and their being conducted in a natural field setting, child protection services agencies. The results indicate that this model of family intervention is an effective alternative to out-of-home placements with this population for approximately 50% of typical child protection services caseloads. The cost benefits of social learning treatments are discussed along with potentially useful clinical and research directions.     

求实精神的恢复与我国的政治思维转型

政治思维的转型是社会政治文化变动的前提。十一届三中全会以来我国政治的发展,正是由于摆脱了“文革”时代形成的“宁要……不要……”,“凡是……就……”的两极思维方式的局限,而走向开放、灵活、宽和的政治思维新模式。认识和研究这种变动,恰是理解二十多年来中国政治发展的门径之一。     

体育教师开发校本课程的动力研究——基于行为改造型激励理论

体育校本课程的开发在新课程改革中具有重要地位,自从《课标》实施以后,校本课程的开发一直不是特别理想。尝试利用行为改造型激励理论去深度剖析影响一线体育教师开发的动力问题,并依据该理论提出改变体育教师消极行为的方法,推动新课标的顺利实施。     

DDP表面修饰ZnS纳米微粒作为润滑油添加剂的SEM研究

利用四球摩擦磨损实验机考察了粒径约为3nm的二烷基二硫代磷酸(DDP)修饰ZnS纳米微粒作为润滑油添加剂的抗磨行为,并用扫描电子显微镜(SEM)和能量散射谱(EDS)等现代分析手段对其摩擦表面进行了分析.结果表明,DDP修饰ZnS纳米微粒作为润滑油添加剂能够明显提高基础油的抗磨能力.SEM及EDS的分析结果表明摩擦过程中在摩擦表面形成了一层富含Zn、S、P元素的反应膜,正是这层膜的存在使得DDP修饰ZnS纳米微粒作为润滑油添加剂具有良好的抗磨性能.     

浅析新刑法中的正当防卫制度

正当防卫制度是刑法中的一个重要内容,由于过去立法上存在一些问题,制约了正当防卫制度的有效实施,新刑法对此做了一些必要的修改。文章在比较新旧刑法关于正当防卫制度规定上的差异的基础上,分析了修改的意义,探讨了如何准确地理解新规定,并对新刑法的修改提出了相应的建议。

混合溶剂中烷偶联剂KH570对纳米ZnO的接枝改性

The reaction of ZnO nanoparticles grafted with KH570 silane coupling agent was carried out in water-alcohol mixed solvent. Several characterization methods were applied to analyzing the results of surface modification such as Soxhlet extraction, Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), thermogravimetry (TG), differential scanning calorimetry (DSC) and zeta potential (ζ). The results of FT-IR and TG-DSC show that the desired reaction chains have been covalently bonded on the surface of ZnO nanoparticles. Zetasizer results reveal that themaximal absolute value of ζ of the modified ZnO particles in acetone medium was 67.0 mV, which was much higher than that of the unmodified ZnO particles. So the surface of nanosized ZnO changed from hydrophilicity to hydrophobicity and the dispersity of ZnO nanoparticles were improved simultaneously. Finally, the mechanism of graft modification was discussed.
