中小企业业务流程再造系统动力模型研究     

饶曦 《中国科技信息》2010,(21)

在企业业务流程再造的过程中,虽然不少企业取得了高额回报,但仍有高达70%的再造项目未能取得预期的回报。选择恰当的时机进行再造是再造成功的关键因素之一,本文在建立中小企业业务流程再造系统动力综合评价指标体系的基础上,构造了中小企业业务流程再造系统动力综合评估的数学模型。  相似文献

Negotiating identity and science teaching in a high-stakes testing environment: an elementary teacher’s perceptions     

Bhaskar Upadhyay 《Cultural Studies of Science Education》2009,4(3):569-586

This study draws upon a qualitative case study to investigate the impact of the high-stakes test environment on an elementary teacher’s identities and the influence of identity maintenance on science teaching. Drawing from social identity theory, I argue that we can gain deep insight into how and why urban elementary science teachers engage in defining and negotiating their identities in practice. In addition, we can further understand how and why science teachers of poor urban students engage in teaching decisions that accommodate school demands and students’ needs to succeed in high-stakes tests. This paper presents in-depth experiences of one elementary teacher as she negotiates her identities and teaching science in school settings that emphasize high-stakes testing. I found that a teacher’s identities generate tensions while teaching science when: (a) schools prioritize high-stakes tests as the benchmark of teacher success and student success; (b) activity-based and participatory science teaching is deemphasized; (c) science teacher of minority students identity is threatened or questioned; and (d) a teacher perceives a threat to one’s identities in the context of high stakes testing. Further, the results suggest that stronger links to identities generate more positive values in teachers, and greater possibilities for positive actions in science classrooms that support minority students’ success in science.

大学对区域经济发展的贡献——以加拿大大西洋省区为例     

饶燕婷 《现代教育论丛》2010,(1):30-35

加拿大大西洋省区在历史上是加拿大较为贫困的地区,当地大学通过为地区经济发展提供人才支持和技术支持,并通过各种消费和购买活动推动了地区经济的发展和产业结构的升级,使该地区在较短时间内弥合了与其他经济发达地区的差距。其成功经验在于政府政策的支持、整体的高等教育战略,以及大学与政府和产业界的紧密合作。  相似文献   

青少年网络成瘾、网络偏差行为与一般问题行为的关系     

王莉  邹泓  任磊  么娆 《中国特殊教育》2010,(8)

以北京市370名中学生为被试,采用网络成瘾问卷、网络偏差行为问卷、一般问题行为问卷考查了青少年网络成瘾与网络偏差行为的关系,并探讨了两者对一般问题行为的影响。结果表明：（1）网络成瘾、网络偏差行为存在显著的性别差异,男生得分均显著高于女生;网络偏差行为存在显著的年级差异,初一学生的网络偏差行为最多;（2）网络偏差行为与网络成瘾呈显著正相关;（3）网络成瘾者比非成瘾者表现出更多的一般问题行为;（4）网络偏差行为在网络成瘾与一般问题行为的关系中起到完全中介作用。  相似文献   

Anhydrobiosis     

T. Ramakrishna Rao 《Resonance》2018,23(5):545-553

In aquatic and moist soil environments subjected to periodic drying, a diverse group of organisms (mostly microscopic) have evolved extreme desiccation tolerance through a physiological adaptation called ‘anhydrobiosis’. Notable among such organisms are tardigrades, bdelloid rotifers, and nematodes. Anhydrobiosis also allows these organisms to tolerate extreme temperatures and ionizing radiation. In this article, the signi-cance and some mechanisms of anhydrobiosis are described.  相似文献   

Trophic Cascades     

T Ramakrishna Rao 《Resonance》2018,23(11):1205-1213

In many ecosystems, apex consumers (top predators) play a crucial role in food web dynamics. Their top-down impacts are known to spread downwards through the food webs in a cascading fashion. Trophic cascades manifest when top predators are excluded from an ecosystem or introduced into a system lacking them. Two such case studies are described here. Trophic cascades are generally more pronounced in the aquatic than in the terrestrial ecosystems, which in turn is related to the differences in the average body sizes of herbivores relative to the plant resources they feed upon and in the structure of their food webs. Scientists express concern that human activities have been leading to planet-wide trophic downgrading (loss of apex consumers) which could affect vital ecological processes of the biosphere.  相似文献

20世纪70年代以来美国高等教育结构调整的特点及启示     

饶燕婷 《中国高教研究》2009,(10)

美国上世纪70年代以来高等教育结构出现了一些调整,在层次结构上大量增加了副学士学位和硕士学位的授予量;在形式结构上,私立大学,尤其是私立营利性大学发展迅猛;在科类结构上,适应经济发展的需要大力发展应用学科.借鉴美国的经验,我国今后的高等教育结构调整要注意与经济发展的协调性,大力发展研究生教育和高等职业技术教育,进一步促进民办高等教育的健康发展,加强学科专业结构与社会经济发展的适应性.  相似文献
