《离骚》与《九章》是否为同一个时期的作品——《离骚》研究系列之四     

冀凡 《黄石理工学院学报(人文社科版)》2006,23(3):47-49

探讨《离骚》与《九章》是否为同一时期的作品,旨在论证《离骚》的创作年代与历史背景,然这在汉代人的载论中是难以解决和论定的,故须从这两部作品的叙事内容的对比研究入手,加以论证其为同一时期的作品,方能从根本上而且极具说服力解决《离骚》的创作年代与历史背景的问题。当前,争论似乎不大,但敢于公然这样论说的学者并不多,这就是撰写此文的意义所在。  相似文献

幻的浪漫梦的真实--论苏、辛的梦幻词     

李海帆  吴帆 《乐山师范学院学报》2005,20(3):13-16

文章首先简述宋人梦幻词的分期。提出苏、辛梦幻词的贡献在于苏、辛借鉴前人的表现手法，尤其是庄、骚、李白以来的浪漫主义手法、创造了梦幻词的诸多范式：天问式、游仙式、骚体式、俳谐式、遥相思念式、诡谲象喻式等。苏、辛梦幻词之异在于苏词清幽而旷达，辛词激越而悲壮沉郁。他们开拓了宋人梦幻词的表现领域，使宋人梦幻词的体式更加完美。  相似文献   

对心理健康教育纳入德育范畴的质疑     

范成祥 《教育科学研究》2006,(9):52-54

心理健康教育与德育的关系是近年来教育界探讨较多的问题。从研究的角度看,将心理健康教育纳入德育范畴会引发许多问题:使德育概念更加泛化,并使德育和心理健康教育难于区分;不利于心理健康教育按其自身的原则和规律科学实施;导致心理问题德育化与德育问题心理化。  相似文献

Allograftic bone marrow-derived mesenchymal stem cells transplanted into heart infarcted model of rabbit to renovate infarcted heart     

王建安  李长岭  樊友启  何红  孙勇 《浙江大学学报(A卷英文版)》2004,5(10):1279-1285

Objective: To investigate the directed transplantation of allograftic bone marrow-derived mesenchymal stem cells (MSCs) in myocardial infarcted (MI) model rabbits. Materials and Methods: Rabbits were divided into 3 groups, heart infarcted model with MSCs transplanted treatment (MSCs group, n=12), heart infarcted model with PBS injection (control group, n=20), sham operation with PBS injection (sham group, n=l 7). MSCs labelled by BrdUrd were injected into the MI area of the MSCs group. The same volume of PBS was injected into the MI area of the control group and sham group. The mortality, LVIDd, LVIDs and LVEF Of the two groups were compared 4 weeks later. Tropomyosin inhibitory component (Tn I) and BrdUrd immunohistochemistry identified the engrafted cells 4 weeks after transplantation. Result: The mortality of the MSCs group was 16.7% (2/12), and remarkably lower than the control group's mortality [35% (7/20) (P＜0.05)].Among the animals that survived for 4 weeks, the LVIDd and LVIDs of the MSCs group after operation were 1.17±0.21 cm and 0.74±0.13 cm, and remarkably lower than those of the model group, which were 1.64±0.14 cm and 1.19±0.12 cm (P＜0.05); the LVEF of the MSCs group after operation was 63±6%, and remarkably higher than that of the model group,which was 53±6% (P＜0.05). Among the 10 cases of animals that survived for 4 weeks in the MSCs group, in 8 cases (80%),the transplanted cells survived in the non MI, MI region and its periphery, and even farther away; part of them differentiated into cardiomyocytes; in 7 cases (70%), the transplanted cells participated in the formation of blood vessel tissue in the MI region. Conclusion: Transplanted allograftic MSCs can survive and differentiate into cardiomyocytes, form the blood vessels in the MI region. MSCs transplantation could improve the heart function after MI.  相似文献   

Usage patterns and social circles on Facebook among elderly people with diverse personality traits     

Fan Mo  Michal Kosinski  David Stillwell 《Educational gerontology》2018,44(4):265-275

Elderly people are exposed to information technologies to keep them in touch with younger generations. Among various technologies, social network sites (SNSs) are seldom used by the majority of elderly people. To bridge the digital divide, it is necessary to dig deeply into the minority elderly users of SNSs. This study explores usage patterns of elderly Facebook users and further investigates how their diverse characteristics influence their usage and social circles. Three findings were derived. First, a sharp digital divide on SNSs does exist, and existing elderly Facebook users are mainly the dabblers. Second, personality profiling could predict elderly people’s SNS usage behaviors. Elderly users with a high level of openness and extroversion have more friends, status updates, and group memberships, and those with a high level of conscientiousness have fewer likes and status updates. Elderly users are likely to seek insightful content on SNSs. Moreover, they may have a higher degree of emotional stability than young users when using SNSs. Third, elderly people tend to build small social circles on SNSs that “copy” the family relationship in the real world; whereas, they build large social circles with interests and hobbies that are difficult to share in the real world. Based on these results, detailed suggestions are presented for better targeting elderly people in ways that move them toward SNSs.  相似文献   

试论开放性管理原则与中国软件企业的管理和发展     

黄璠  欧阳电平 《湖北广播电视大学学报》2001,18(1):54-58

开放性管理原则是指在对企业资源特别是人才和技术资源合理模块化基础上进行结构化配置和管理，以高效简明的接口规范内部的交流和外部扩展；同时，将“可持续性的利润最大化”作为企业管理和发展的始发点和最终决策依据，放开管理和发展的思路，用这种原则指导软件企业的管理和指引发展，实质上就是从软件企业的特点出发分别致力于对内的自我激励和自我约束，以及对外的积极扩充和协调发展，也即内涵的管理和外延的拓展，核心思想就是开放性。  相似文献   

关于文学性以及文学研究问题     

南帆 《江苏理工大学学报(社会科学版)》2005,7(6):56-61

过去的几年里，“文学性”这个概念成为文学研究的一个焦点。其考察大致形成了两个派别的观点，一派被视为本质主义的，例如“纯文学”的概念就是本质主义观点的派生物；一派被视为非本质主义的，认为所谓的本质仅仅是一种幻觉。前者处理的问题较为简单，后者却是将自己置于不尽的问题之流中。与此相关，文学研究的成果是一种知识。知识具有多种形态，科学知识仅仅是一种形态，文学研究以及其他人文学科的研究显示的是另一些知识形态的意义。文学研究时常出现从概念定义出发来衡量具体的文学现象，而文化研究很大程度上就是用具体的分析抵制形而上学的理论趣味。联系后殖民理论来分析中国古代文论的现代转换问题：援引西方的术语范畴可以阐释民族文化的特征，甚至成为反击文化殖民的手段。如果中国古代文论的概念、命题无法企及现今的理论高度，或者远远地游离于现今的历史语境，那么，这种理论就无法承担“现代转换”的使命。  相似文献
