Untangling the Net     

《Journal of Teaching in Social Work》2013,33(3-4):37-51

Abstract

The importance of computer training in social work education will continue to increase as the profession becomes more globalized and technological. It is the authors' premise that social work education must include the integration of training in computer technology. One resource available to educators is the Internet. The world wide web contains a vast amount of information on policy and social issues. This article discusses the use of web based learning exercises to simultaneously teach social policy and enhance student computer skills. Two learning exercises are presented which are designed for use in social work policy courses. The authors present their teaching experiences and provide suggestions on using this approach in the classroom environment. Information on resources and useful URL's for policy research is included in the discussion.  相似文献   

Technology Acceptance in Social Work Education: Implications for the Field Practicum     

Alex Don Colvin  Angela N. Bullock 《Journal of Teaching in Social Work》2013,33(5):496-513

The exponential growth and sophistication of new information and computer technology (ICT) have greatly influenced human interactions and provided new metaphors for understanding the world. The acceptance and integration of ICT into social work field education are examined here using the technological acceptance model. This article also explores potential challenges regarding the adoption of ICT into social work field practica. The article concludes with implications for adopting and integrating ICTs in social work field education.  相似文献   

基于数值流形法的计算机动画建模     

刘婷婷  王颖 《中国科学院大学学报》2008,26(6):843-848

基于物理规律的计算机动画一直是图形学领域的研究热点,将一种新的动力学分析方法数值流形法引入到计算机动画领域中,利用数值流形法建立连续与非连续变形体的统一物理模型,仿真了一个逐渐展开的卷曲橡皮条、一个小球落到一堆可变形正方块上,以及一个球经过旋转的齿轮的情形。仿真结果显示,该模型可以处理多变形体的大位移和大变形,也可以处理变形体中裂隙的张开和滑移。  相似文献

公共选修课《计算机网络》的教学思考与实践     

李宗辉  刘小铭 《湖北生态工程职业技术学院学报》2009,(2)

作为面向全校学生选修的公共课程,《计算机网络》在许多方面具有特殊的课程性质。课程的教学对象参差不齐,多数缺乏必要的计算机基础知识,对课程本身缺乏了解;课程教学内容的取材要求精简、合理,教师在讲授过程中要能够把握课堂教学过程的要点。  相似文献   

At the foundations of information justice     

Matthew P. Butcher 《Ethics and Information Technology》2009,11(1):57-69

Is there such a thing as information justice? In this paper, I argue that the current state of the information economy, particularly as it regards information and computing technology (ICT), is unjust, conferring power disproportionately on the information-wealthy at great expense to the information-poor. As ICT becomes the primary method for accessing and manipulating information, it ought to be treated as a foundational layer of the information economy. I argue that by maximizing the liberties (freedom to use, freedom to distribute, freedom to modify, and so on) associated with certain computer software, an incentives-rich and stable environment can be established in ICT that will foster development of the information economy among the information poor. I suggest that the now-mature Free and Open Source Software paradigm, which has already produced widely-used enterprise-class applications, can be harnessed in support of these ends.  相似文献

糖酵解供能真假超量恢复区间的探析   总被引：5，自引：1，他引：4  

殷劲  岳建兴  朱伟  石金丽  殷维瑶 《成都体育学院学报》2008,34(10)

超量恢复规律鲜有成功应用的报道,是理论还是实践出了偏差? 为此,文章将通过对真、假超量恢复区间的研究,初探供实践之用的恢复理论.方法:大鼠147只,随机分21组;造模1周后,游泳训练2周.按36h超量恢复区间连续在训练后即刻、休息36h取样.结果:超量恢复组①心脏:前6×36h区间适应期、正叠加,第7区间极限,8-9区间负叠加过程;②肝脏:前4区间正叠加,第5区间极限,6-9区间负叠加过程;③肾脏:前4区间正叠加,第5区间极限,6-9区间负叠加过程;④糖酵解供能:前4区间正叠加,第5区间极限,6-9区间负叠加过程.结论:①超量恢复区间含正、负叠加过程,即真、假超量恢复区间;②负叠加过程的发展终导致过劳死发生,正、负叠加过程的转折点为生理极限.  相似文献
