屈原由于其忧愤深广的爱国情怀，尤其是为了理想而顽强不屈地对现实进行批判的精神，为中国文化增添了一股深沉而刚烈之气。楚国历史上传统的战斗精神表现在屈原作品中，较之《诗经》，《楚辞》主题的战斗性大大加强了。  相似文献

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

对双生子佯谬问题的探讨     

王忠先 《呼伦贝尔学院学报》2007,15(1):61-63

双生子佯谬的提出,是假定地球和火箭是两个完全等价的惯性系,这个前提是明显错误的,其实无论从地球,还是火箭角度出发利用狭义相对论的理论,都推导出火箭上的孪生兄弟比地球上的孪生兄弟要年轻。  相似文献

影响高校毕业生就业的社会资本因素分析   总被引：3，自引：0，他引：3  

阎凤桥  毛丹 《复旦教育论坛》2008,6(4):56-65

社会资本是近年来学术界研究较多的一个问题。本文在对社会资本及大学生就业相关文献进行梳理的基础上,利用北京大学教育学院"高等教育规模扩展与劳动力市场"课题组于2005年6月对全国34所高校调查的数据,对大学生社会资本状况,社会资本对大学生毕业去向、就业落实率、起薪及工作满意度的影响,进行了实证分析。本文的主要研究结果如下:(1)与来自社会经济地位较高的家庭的学生相比,来自社会弱势家庭的学生在家庭社会资本与个人社会资本上都比较缺乏;(2)大学生毕业选择就业或升学时,家庭社会交往广泛度对升学选择产生显著的正面影响,而个人社会交往广泛度对就业产生了显著的正面影响;(3)社会资本与大学毕业生的就业落实、起薪、工作满意度存在着显著的正面影响;(4)社会资本对大专生和本科生就业落实率有较为显著的正的影响,但是对硕士和博士的就业落实率没有显著影响。  相似文献   

和谐社会视角下农民养老保障问题研究     

张百顺  王秋红 《贺州学院学报》2007,23(1):11-15

社会保障制度是社会的安全网和稳定器,也是构建社会主义和谐社会的重要组成部分.由于我国长期受城乡分割的二元社会保障制度的影响,目前农民养老保障仍然主要依靠传统的家庭养老和土地保障形式.在人口老龄化与工业化、城镇化迅猛发展的今天,传统的保障形式正在遭遇前所未有的挑战.如何应对农民养老风险,解决农民老有所养的问题,是摆在我们面前一个严峻而紧迫的问题.也是二十一世纪我国落实科学发展观,构建社会主义和谐社会必须直面的问题.  相似文献

Forming shared inquiry structures to support knowledge building in a grade 5 community     

Dan Tao  Jianwei Zhang 《Instructional Science》2018,46(4):563-592

This study explores the reflective processes by which a grade 5 science community co-constructed shared inquiry structures to focus and guide its inquiry about human body systems over a school year supported by a collaborative online environment. The co-constructed structures included a list of collective wondering areas as the shared focus of inquiry and models of the inquiry process in the form of “research cycle.” Qualitative analyses of field notes, classroom videos, student notebooks and interviews elaborate the evolution of the inquiry areas and the “research cycle” model as well as students’ adaptive use of the structures to guide deeper inquiry. Content analyses of students’ individual research questions and collaborative online discourse indicate that students used the structures to develop more advanced inquiry and make productive contributions. The results contribute to elaborating a reflective structuration approach to co-organizing and sustaining long-term, open-ended inquiry in knowledge building communities.  相似文献
