Erosion behavior and mechanism of boronised steels     

刘立  凌国平  刘涛  郦剑 《浙江大学学报(A卷英文版)》2002,3(3):278-282

Boronising of steels is a hardening process to get high surface hardness. The erosion resistance of boronised steels was researched with the use of four kinds of erodent, i.e. glass, alumina, quartz and silicon carbide. The erosion rate increases rapidly with erodent hardness and severe erosion occurs with high impacting angle range of hard particles. SEM analysis indicated that chipping is caused by repetitive impacting of glass and quartz, whereas by alumina and silicon carbide impacting, chipping, and that plastic flow take place simultaneously and the erosion rate reaches the peak value when the impacting angle is above 60°.  相似文献

现当代管理心理学领导行为与领导风格研究成果综述   总被引：1，自引：0，他引：1  

张海钟  赵文进  张维英 《兰州石化职业技术学院学报》2006,6(4):56-60

通过对现代管理心理学中领导行为和领导风格研究成果的综述认为,西方管理心理学研究的结论在中国的推广存在严重的文化障碍,必须逐步本土化才能用来指导中国的党政管理和企业管理.20世纪的中国管理心理学关于领导行为和领导作风的研究,要么停留在西方管理心理学的介绍和跨文化验证方面,要么以西方文化为背景,批评中国企业家没有现代管理的心理素质,对中国古代儒家道家文化背景下形成的治国治家思想和以党的执政理论为框架的领导科学视而不见.西方的管理心理学和中国的领导科学就象两条铁轨,难以相交,主要的障碍在于话语的转换困难.心理学的本土化道路仍然很漫长.  相似文献   

Children’s Memory: A Primer for Understanding Behavior     

Elaine S. Barry 《Early Childhood Education Journal》2006,33(6):405-411

This paper provides the opportunity to understand children’s behavior from a memory viewpoint. For the last three decades, cognitive developmentalists have been asking the question, “what develops in children’s memory?” Four answers to this question are presented, complete with explanations, examples, and possible applications where appropriate. The purpose of the paper is to provide early childhood educators and other practitioners who work with children a different lens through which to view children’s behavior. The memory view is compatible with current best practices in early childhood education, and may provide practitioners an additional viewpoint from which to draw when implementing developmentally appropriate practice.  相似文献

Pricing policy and the college choice process     

Dr. Randall G. Chapman 《Research in higher education》1979,10(1):37-57

Following the presentation of a marketing management paradigm for higher educational institutions, this paper discuses some aspects of the pricing policy process in colleges and universities. A statistical model of the college choice process is developed, and some empirical results related to the effects of price, among other factors, on the collegechoice decision-making behavior process of high school seniors are presented and interpreted. The two most important factors affecting the college choice process are seen to be college quality and price-related considerations. Marketing implications of these results are discussed.Presented at the Annual Forum of the Association For Institutional Research, Houston, Texas, May 1978.  相似文献   

The relative impact of school‐wide positive behavior support on teachers’ perceptions of student behavior across schools,teachers, and students     

Albert W. Wienen  Inge Reijnders  Marleen H. van Aggelen  Elske H. Bos  Laura Batstra  Peter de Jonge 《Psychology in the schools》2019,56(2):232-241

School‐wide positive behavior support (SWPBS) is a systemic approach for implementing a proactive schoolwide discipline and for improving students’ academic and behavioral outcomes by targeting the school’s organizational and social culture. With a multilevel approach, the present study evaluates the relative effectiveness of SWPBS on teachers’ perceptions of the student behavior (N = 3,295) across schools, teachers, and children using a multilevel approach. We assessed teacher perception of student problem behavior five times during a 3‐year implementation of SWPBS in 23 Dutch schools. Multilevel analyses not only revealed a small increase in perceived prosocial behavior and a small decrease in problems with peers, but also different effects across children, teachers, and schools. Effects were stronger for girls and for students with higher severity of perceived problems at baseline. At teachers’ level, higher mean baseline severity of perceived problems was associated with the reduced impact of SWPBS on perceived emotional problems and problems with peers. At the school level, effects were stronger for regular schools as compared with special needs schools.  相似文献   

同伴接纳与流动儿童外化问题行为的关系:自尊和物质主义的链式中介作用     

张春妹  丁一鸣  陈雪  周长新 《中国特殊教育》2020,(1):65-72

本研究探讨同伴接纳对流动儿童的外化问题行为的影响,以及自尊、物质主义的链式中介作用。在武汉市三所小学选取478名五、六年级的流动儿童,运用同伴提名法、物质主义价值观量表-儿童版(MVS-c)、自尊量表(SES)、儿童青少年问题行为问卷(CB)进行问卷调查。结果发现,同伴接纳、物质主义价值观、自尊、外化问题行为四者均显著相关;同伴接纳对外化问题行为具有很强的直接预测作用,也会通过物质主义价值观和自尊的部分中介作用而影响外化问题行为,还会通过自尊、物质主义的链式中介作用影响外化问题行为。  相似文献   

行政诉讼中原告资格问题探讨     

李蕊 《黄冈师范学院学报》2004,24(2):9-12

我国行政诉讼原告资格限制过于严格，有碍公民宪法权利和依法行政目标的实现，也日益暴露出与世界法治趋势不相一致的矛盾，应当予以调整。涉及公共利益损害的行政诉讼，实行“公民有权”原则，规章及以下层次抽象行政行为、行政行为合理性问题应纳入行政诉讼的范围，缩小行政终局裁决的范围，赋予更多的行政相对人以原告诉讼资格。  相似文献
