Study of serum lipid profile in pregnancy induced hypertension     

Jayanta De  Ananda Mukhopadhyay  Pradip Kumar Saha 《Indian journal of clinical biochemistry : IJCB》2006,21(2):165-168

Four groups of subjects: normal healthy normotensive nonpregnant women (Group A), normal normotensive pregnant women (Group B), women with preeclamptic toxaemia (Group C) and eclamptic women (Group D): with fifty subjects in each group, were investigated for serum lipid profile in the third trimester of pregnancy. There was significant increase in serum triglyceride and VLDL cholesterol leve as well as decrease in LDL cholesterol in normal pregnancy, while total cholesterol and HDL cholesterol levels did not show any statistically significant alteration. The preeclampsia (Group C) was associated with a significant rise in triglyceride and VLDL cholesterol and fall in HDL cholesterol concentration, while eclamptic women showed significant fall in HDL cholesterol and rise in LDL cholesterol as compared to normal pregnant women. However, interestingly, elevation of the ratios of total cholesterol: HDL cholesterol and triglyceride: HDL cholesterol as well as diminuition of the ratio of HDL cholesterol: VLDL cholesterol showed statistical significance in pregnancy induced hypertension in both Groups C and D, while eclamptic women showed significant elevation of LDL cholesterol: HDL cholesterol ratio in addition.  相似文献   

我国外贸增长空间的实证分析     

李恩义  牛德强  孙健 《中国软科学》2002,(2):33-35

中国经济自改革开放以来的高速增长与对外贸易的快速增长密不可分。在与世界主要发达市场经济国家比较的基础上,本文从贸易依存度的角度进行实证分析,指出中国外贸的增长已经达到顶点,靠持续的外贸增长推动经济增长的空间已经很小。从长期看,必须依靠扩大内需来推动经济持续健康快速增长。  相似文献

Developing capabilities in new ventures: a knowledge management approach     

Marco?Bettiol  Valentina?De Marchi  Eleonora?Di MariaEmail author 《知识管理研究与实践》2016,14(2):186-194

On the basis of a knowledge management perspective, this paper expands the literature on new ventures’ capabilities by considering how these firms fill knowledge gaps and develop the technological, marketing, management, and ICT capabilities they need to compete. In particular, this paper investigates the role of networks in these dynamics. Although new technology-based firms have great potential to introduce innovative products into the market, they might suffer from more critical knowledge gaps and capability weaknesses than established firms. The results of a quantitative investigation of an original data set of more than 400 Italian new ventures specializing in high-tech industries show that these firms acquire knowledge to support their capability growth mainly through the management of intense relations with multiple external sources of knowledge. In addition, capability development is supported by the variety of founders’ industry experience and the presence of young graduates among the founding team.  相似文献   

"泄导人情"论与"白居易现象"     

简德彬 《湖南城市学院学报》2000,(2):7-12

"泄导人情"是白居易在《与元九书》中提出的一个重要的诗学命题。追溯白居易"泄导"理论的历史渊源,考察白居易的"泄导人情"实践即其绵延几十年的诗歌创作,分析白居易诗歌创作实践所遭遇到的深刻的现实矛盾,可以把白居易的"泄导"理论及实践在现实中遭遇到的种种矛盾统称为"白居易现象"。这一"现象"昭示着早在白居易时代,中国传统文化心理--行为模式的修补、重建已经不可避免。  相似文献   

Tablets as an educational tool for enhancing preschool science     

Melina Furman  Susan De Angelis  Enzo Dominguez Prost  Inés Taylor 《International Journal of Early Years Education》2019,27(1):6-19

Information communication technologies (ICT) is increasingly being introduced in the preschool level, but questions have been raised regarding its potential to develop content knowledge or specific skills. This quasi-experimental study looked into the impact that hand-held tablets can have on science learning outcomes in five-year-olds. Four classes from two preschool institutions in Buenos Aires, Argentina, were selected for a six-week intervention. All four classes received training and an inquiry-based science teaching sequence, with one group from each institution also receiving tablets and specific guidance on how to incorporate them into their science lessons. Post-intervention test results showed significant improvements in science outcomes for all students, but no significant difference between the tablet-enhanced classrooms and those taught without ICT. Challenges and opportunities are discussed with regard to including tablets for teaching science at the preschool level.  相似文献

解德枫 《南阳师范学院学报》2002,1(3):47-50

《狂人日记》，就其显在结构和表层的社会意义而言，是一篇“暴露家族制度和礼教的弊害”的控诉书，就其隐在结构和作的主观心灵投射而言，它又是一篇忏悔和绝望之作。运用本细读和传记批评的方法，可对其复杂的意蕴作出阐释。  相似文献

步德胜  王磊  马冀 《忻州师范专科学校学报》2008,(4):99-101

“中国近现代史纲要”是新形势下高校开设的一门公共必修课,该课具有历史课与政治理论课的双重特点,有利于完善高校思想政治理论课程体系,有利于改变青年大学生淡忘历史的现象,有利于培养青年学生的爱国主义观念和高尚的道德情操。经过几年的教学实践,我们体会到,要顺利实现开课目的,必须制定正确的教学原则、教学方针、教学目标、教学内容、教学方法和考核方式。  相似文献   

我国农业资源法制建设问题探讨
