1中国英语本科学生素质调查报告显示文摘本项调查以6所外语学院250名二年级学生为对象用11种测量手段,对与英语学习成绩有关的17项自变量和13项社会心理因素进行测试。统计结果显示,6种因素对学生的英语学习成绩影响最大:语言学能,学习动机,院校类型,性别,中学类型,和场独立型的认知方式;63.4%的学习差异是这6种因素引起的。吴一安 刘润清 P.Jeffrey 1993外语教学与研究1993,25,1:452
2全新世大暖期对青藏高原东北缘人类活动的影响显示文摘结合环境演变资料与考古发现,全新世大暖期暖湿的气候条件,促进了青藏高原东北缘古文化的发展。表现在:随着全新世大暖期暖湿环境的到来,人类活动强度大大增强;细石器文化活动模式发生显著改变,由晚更新世末期一全新世早期的短暂宿营式居住模式演变为相对固定的聚落模式;暖期中较好的水热条件,刺激了仰韶、马家窑文化在本区东部河谷地区的扩张,在暖期的6~4kaBP形成了东部河谷地带马家窑文化,西部高原细石器文化并存的区系格局,两种文化体系在共存中交流,在交流中高原细石器文化掌握了农业种植、使用了陶器,全面推动了高原土著文化进入新石器。侯光良 赖忠平 孙永娟 P.Jeffrey BRANTINGHAM 2013干旱区地理2013,36,6:5
3Deep Learning for Real-Time Crime Forecasting and Its Ternarization显示文摘Real-time crime forecasting is important.However,accurate prediction of when and where the next crime will happen is difficult.No known physical model provides a reasonable approximation to such a complex system.Historical crime data are sparse in both space and time and the signal of interests is weak.In this work,the authors first present a proper representation of crime data.The authors then adapt the spatial temporal residual network on the well represented data to predict the distribution of crime in Los Angeles at the scale of hours in neighborhood-sized parcels.These experiments as well as comparisons with several existing approaches to prediction demonstrate the superiority of the proposed model in terms of accuracy.Finally,the authors present a ternarization technique to address the resource consumption issue for its deployment in real world.This work is an extension of our short conference proceeding paper[Wang,B.,Zhang,D.,Zhang,D.H.,et al.,Deep learning for real time Crime forecasting,2017,ar Xiv:1707.03340].Bao WANG Penghang YIN Andrea Louise BERTOZZI P.Jeffrey BRANTINGHAM Stanley Joel OSHER Jack XIN 2019Chinese Annals of Mathematics,Series B2019,40,6:2
