Developmental and Psychological Aspects of the Savant Syndrome     

Michael L. Wehmeyer 《International Journal of Disability, Development & Education》1992,39(2):153-163

A savant is a person with intellectual disability who demonstrates one or more skills above the level expected of someone without intellectual disability. These skills take the form of exceptional musical, artistic or mechanical abilities, prodigious memorization or mathematical talents, and most commonly, the ability to calculate with rapidity the day of the week upon which any given date, past or future, falls. Reported throughout much of this century as objects of amazement, and familiar through the popular press to the general public, there has been a recent surge in experimental studies attempting to describe components of the development of savant abilities, and to determine mental processes used to accomplish these tasks. This survey examines the psychological aspects of the savant syndrome, focusing on the means by which certain abilities, particularly calendar calculation, are accomplished, and highlighting variables postulated as important for development of the syndrome. Implications for the education of students with intellectual and developmental disabilities are discussed, including the relevance of this literature to theories of general intelligence.  相似文献   

Sands modeling constrained by high-resolution seismic data     

ZHANG Feng LI Zhi-ping WANG He-lin WU Jian TAN Zhen-hua 《浙江大学学报(A卷英文版)》2007,8(11):1858-1863

In the phase of field evaluation, the changing of interwell reservoir may be out of control if the geological model was built only on well data due to few existing wells. The uncertainty of the interwell reservoir interpolation based only on well data can be decreased by comprehensive utilization of geological, logging and seismic data, especially by using highly relative seismic properties from 3D seismic data adjusted by well point data to restrict interpolation of geological properties. A 3D-geological model which takes the sand body as the direct modeling object was built through stacking the structure, reservoir and water/oil/gas properties together in 3D space.  相似文献   

不确定性、国际合作困境与国家对相对收益的考虑     

韩召颖  姜潭 《安徽师范大学学报(人文社会科学版)》2018,46(3):29-35

对于当前国际政治现象最突出的特征——不确定性的增强及国际合作的困境——如何在理论上进行科学的认识和解释?在回顾既有文献的基础上,可以从相对收益的视角对当前国际政治现象进行解释.在当前国际形势下,美欧等西方国家对于相对收益的考虑增强,在国际交往中更加强调维护国家的主权利益,因此出现了主张"本国优先,反全球化,限制外国移民"等"逆全球化"的动向以及鼓吹民粹主义、孤立主义和保护主义等"反建制"的思潮,国际合作进程因而陷入困境.对特朗普执政后美国在国际贸易、全球气候治理中的态度和行为进行分析,可以发现相对收益的考虑极大影响了国家在国际合作中的行为.  相似文献   

先秦法家人物个人悲剧原因考     

谭宝刚 《沙洋师范高等专科学校学报》2003,4(3):51-54

以前学术界认为，先秦法家人物的个人悲剧是由旧势力的反扑造成的，但这仅是表层现象，实际上有更深层次的原因。笔者认为先秦法家人物个人悲剧的真正原因是：前期法家人物的个人悲剧是自己行为与主张相悖的结果；后期法家人物的个人悲剧是法家人物内部不同派别之间斗争的结果。先秦法家人物虽然大都落得一个可悲的结局，但是他们的思想主张得以流传后世，取得了胜利，从而弥补了历史的遗憾。  相似文献

高职高专应用型法律人才培养模式的构建——以法律职业改革为视角   总被引：3，自引：0，他引：3  

谭建淋 《新疆教育学院学报》2006,22(2):40-42

高职高专法学教育是高等法学教育的重要组成部分。适应法律职业改革的趋势和需要,高职高专法律专业人才培养的模式必须转换。要在继续提高传统法学教育质量的同时,根据社会需求重新确定高职高专法律人才培养目标,改革培养的方式与途径,着力探索和构建以培养学生应用能力为主要目标,符合社会进步发展需要的应用型法律人才培养模式。  相似文献   

The C.B.S. Problem in American Radio Historiography     

Michael J. Socolow 《Journal of Radio & Audio Media》2016,23(2):323-334

The Columbia Broadcasting System (C.B.S.) emerged in the late 1920s as the only sustainable competitor to the National Broadcasting Company (NBC) in American network radio. But scholars know far less about C.B.S. than NBC because the C.B.S. corporation failed to retain, and make accessible to media historians, internal archival and documentary materials from its developmental era. This article examines the historical void created by America’s second network while offering two specific historical case studies to establish how the loss of C.B.S. materials continues to hinder knowledge about America’s second network, the American system of broadcasting, and the political economy of the commercial mass media in the United States.  相似文献   

太空垃圾与财富     

赵琳 《海外英语》2007,(7):83

即使是一块细小的漆片,如果残留在运行轨道上,也会给一搜时速17500英里的时空穿梭机的窗户上留下划痕.为了避免这类灾难性的碰撞,(美国)国防部追踪运行在轨道周围的超过2英寸大的宇宙垃圾.悬浮的碎片大多与地球有着密切的关系,比如,1965年从爱德华·怀特手上脱落的一只手套,或是2004年俄罗斯太空船的一块太阳能板上松动掉落的吊环螺栓,在大气中迅速燃尽.更高轨道上的项目对数代人来说仍很艰巨:"先锋一号"卫星将飞行数世纪之久.  相似文献   

基于SQL Server的权数确定的算法分析     

谭杰锋  周苏峡 《北京教育学院学报》2007,2(2):8-11

确定评价因素在评价指标体系中的权重系数,是评价工作的关键之一.通常使用的CHR法确定权数,必须经过大量复杂的计算,利用SQL Server的数据库功能,实现基于网络环境的多点并发操作,可以简化计算.本文通过实例讨论了其算法,给出了应用软件.  相似文献
