知识产权保险制度可行性研究     

毕波  吴承磊 《佳木斯教育学院学报》2016,(4):145

在全球经济一体化的时代,知识产权成为我国企业增强自我实力并拓展国内外市场的核心竞争力。但是,面临侵犯其他企业的知识产权而承担巨额赔偿的风险下,往往限制了企业的市场开发和拓展;同时,在受到第三人的侵权情形下,许多企业由于经济和时间等维权成本的考量会消极维权,甚至放弃维权。引入知识产权保险制度以分散权利人以及侵权人的风险,为企业的业务开展和市场开拓提供充分的保障。  相似文献   

比较文学：越界与融通——兼评马焯荣先生的“泛比较文学论”     

何云波 《四川师范大学学报(社会科学版)》2007,34(1):95-100

当今围绕比较文学的“危机”有种种争论。一些学者认为,危机乃是源于当初“比较文学”这一学科的命名本身就是名不副实的,它导致了后来种种混乱的产生,使比较文学越来越走向无边与无根。走出危机,首先需要正名,重新回到法国学派。而有的学者则反过来提出了“泛比较文学论”的概念,主张进一步扩大比较文学的研究范围。其实,真正的问题在于,当今关于比较文学学科边界的争论,根源不在于所研究的那些东西是否有意义,而是学科之间画地为牢、占山为王的结果。其实,“未完成”反而意味着变化与新生的可能,围绕比较文学学科现状与未来的种种“焦虑”也就大可不必了。  相似文献

Phenomenography — a “good‐for‐nothing brother” of phenomenology? Outline of an analysis     

Biörn Hasselgren  Dennis Beach 《高等教育研究与发展》1997,16(2):191-202

This article will argue that five different ways of doing phenomenography can be found amongst the works of Gothenburg phenomenographers: Discursive, Experimental, Naturalistic, Hermeneutic and Phenomenological. Commenting on an earlier version of phenomenography, Jacob Needleman stated that it was “a ‘good‐for‐nothing’ brother of phenomenology”. We will argue that it is not. It is productive research, even if at times the degree of methodological reflection applied by phenomenographers to their work is found wanting. Two of five forms of Gothenburg phenomenography can be developed by recourse to phenomenology.  相似文献   

避免分组丢失切换方法     

余旭涛  王霄峻  毕光国 《东南大学学报》2003,19(3):212-215

针对基本移动IP协议虽然简单但只适用于大范围、低速的情况，提出了一种新的微观移动IP切换方法——避免分组丢失切换方法．该切换方法通过在基站处增加缓存以及利用IP分组的标识，将切换过程中分组丢失减少至最小．并给出了该切换方法所适用的分层全IP网络结构及其切换过程，对基站缓存的大小、切换带来的网络负荷、切换延时等也进行了分析．仿真和分析结果表明最小分组丢失切换方法适用于快速移动、频繁切换的环境．  相似文献

认知结构理论的扩展化：自我调节学习的建构主义理论     

曾碧 《甘肃高师学报》2008,13(6):78-80

认知结构理论的扩展化时期,众多认知心理学家不断扩充认知结构理论,对认知结构的过程和机制进行了具体而细微的研究,为真正的课堂教学提供了广泛而具体的指导。自我调节学习近20年来得到了广泛关注,成为教育心理学的研究热点,自我调节学习是有效地进行学习和解决问题的主要方面,能够促进学习在新情景中的迁移。学生的自我调节学习过程中存在三个影响因素即个人、环境和行为。自我调节学习的建构主义理论是认知结构理论在扩展化时期发展的重要代表之一,是指在学习活动中建构自我调节学习的理论。这些理论包括四方面的内容：即自我能力理论、努力程度理论、学习任务理论和学习策略理论。  相似文献   

Relationship between Perceptions of Control and Victimization of Chinese Adolescents     

Bi Zhu  Li Lei 《Frontiers of Education in China》2006,1(1):153-160

This study explores perceptions of control in victims of school bullying, by surveying 108 adolescents with questionnaires. The result shows that there are significant gender differences in external control in general, internal control of sociality, and victimization of physical bullying. Physical victimization decreases as subjects grow older, but unknown control increases. Social victimization is positively correlated with all factors of external control. Verbal victimization is positively correlated with factors of external control of sociality, general and average; and negatively correlated with factors of internal control of sociality and physicality. Victimization of property bullying is positively correlated with average external control. External control is a predictor of victimization of social, verbal, and property bullying; internal control of body is that of verbal victimization.

Xing HC  Li LJ  Xu KJ  Shen T  Chen YB  Sheng JF  Yu YS  Chen YG 《Journal of Zhejiang University. Science. B》2005,6(1):14-21

Objectives:To investigate the intestinal microflora status related to ischemia/reperfusion(I/R)liver injury and explorethe possible mechanism.Methods:Specific pathogen free grade Sprague-Dawley rats were randomized into three groups:Controlgroup(n=8),sham group(n=6)and I/R group(n=10).Rats in the control group did not receive any treatment,rats in the I/R groupwere subjected to 20 min of liver ischemia,and rats in the sham group were only subjected to sham operation.Twenty-two hourslater,the rats were sacrificed and liver enzymes and malondialdehyde(MDA),superoxide dismutase(SOD),serum endotoxin,intestinal bacterial counts,intestinal mucosal histology,bacterial translocation to mesenteric lymph nodes,liver,spleen,andkidney were studied.Results:Ischemia/reperfusion increased liver enzymes,MDA,decreased SOD,and was associated withplasma endotoxin elevation in the I/R group campared to those in the sham group.Intestinal Bifidobacteria and Lactobacillidecreased and intestinal Enterobacterium and Enterococcus  相似文献
