垮掉派与意识革命

现代资本主义社会采取了与传统社会完全不同的统治策略:通过市场和商品,控制人们的意识。在文化被市场化、商品化的背景下,作家有适应和拒绝两种生活方式。波德莱尔以来,拒绝者开创了文艺领域中的“波希米亚人”的流浪传统。垮掉派是这种传统的继承者和发展者,他们的行为和创作具有强烈的意识革命含义。     

一种基于ERDAS软件在TM影像中提取较小水体的方法

本文对从landsat影像中提取细小水体的方法作了研究,基于ERDAS软件用新的识别方法提取较小水体。利用谱间模型提取TM影像中较大水体,再将TM影像中某3个波段组成的假彩色合成图转换到IHS彩色空间,构建模型提取细小水体,并与前者识别结果进行叠加,获得较好效果,证明在实际中可用。     

金斯伯格《嚎叫》的文化效果及其成因探微

金斯伯格是美国"垮掉的一代"(Beat Generation)的代表诗人.他的代表作品<嚎叫>,以其激动人心的魅力被世人传送.<嚎叫>问世后,由于它思想"偏激",语言粗俗,曾被指控为"淫猥"而受到审判.但随着时间的推移,人们认识到<嚎叫>是一篇精湛的艺术品.更是一篇流利的战斗檄文.本文主要从社会历史文化价值、创作风格、写作手法以及促进中美文化交流等四个方面,探讨了<嚎叫>的文化效果,并揭示了其背后的深层原因,旨在以辩证的态度接受<嚎叫>,借鉴诗文的积极意义.     

基于视频压缩编码的动态图像水印方案

提出了一种新的基于视频压缩编码的动态图像水印方案。在嵌入水印时,充分考虑动态图像压缩编码的特性,对帧内编码帧(I帧),将水印信息嵌入到DCT低频系数中;而对帧间编码帧(P,B帧),结合动态补偿/离散余弦变换(MC/DCT)混介编码,把水印信息嵌入到运动补偿后的残差图像的自流成分中。同时,在水印嵌入时,采用扩频技术与多维水印相结合的方法,并通过相关检测的方法判断水印的存在。由于水印的检测是对视频码流直接实施的,不需要对压缩数据进行完全解码,从而大大降低了计算量,提高了视频数据水印的适用性。     

垮掉一代的精神探索与《在路上》的意义

发生在20世纪中期的美国垮掉派运动挑战由冷战狂热与清教传统共同创造的高压社会和主流文化.垮掉一代在本质上是叛逆者和探索者.这场运动的主要意义在于它对压抑人性的主流意识形态的叛逆和探寻新的信仰、探寻如何在现代世界维护和发展人性所做的精神探索.凯鲁亚克的小说<在路上>最全面地表现了垮掉一代的生活方式和最深刻地探索他们不懈的精神追求,同时也揭示了他们身上的弱点,可以说是垮掉派运动发展的"启示录".     

中国种子植物特有属的数量分析

Chinese flora with many endemic elements is highly important in the world’s flora. According to recent statistics there are about 196 genera of spermatophytes, be- ing 6.5% of total Chinese genera.  These endemic genera comprising 377 species belong to 68 families, among which the Gesneriaceae (28 genera), Umbelliferae (13), Compo- sitae (13), Orchidaceae (12) and Labiatae (10) are predominant.  The tropical type containing 24 families and 80 genera is dominant. After it follows the temperate type with 23 families and 50 genera.  There are also 4 families endemic to China, i.e. Gin- kgoaceae, Bretschneideraceae, Eucommiaceae and Davidiaceae.  It shows that genera endemic to China are obviously related to the tropical and temperate flora in essence.      The endemic monotypic genera (139) and endemic obligotypic genera (48) combin- ed make up more than 95% of the total number of genera endemic to China.  Phylo- genetically more than half of them are ancient or primitive.  The life forms of all ende- mic genera are also diverse.  Herbs, especially perennial herbs, prevail with the propor- tion of about 62%, and trees and shrubs are the next, with 33%, and the rest are lianas.       Based upon the calculated number of genera endemic to China in each province and the similarity coefficents between any two provinces, some conclusions may be drawn as follows:       Yunnan and Sichuan Provinces combined are the distribution centre of genera en- demic to China and may be their original or  differentiation area,  because  numerous endemic genera, including various groups, exist in these two provinces.  The second is Guizhou where there are 62 endemic genera.  Others form a declining order, south China, central China and east China. But towards the north China endemic genera de- crease gradually, and the Qinling Range is an important distributional limit.       The largest simitarity coefficient, over 50%, appears between Shaanxi and Gansu probably because of the Qinling Range linking these two provinces.  But between any other two provinces it is less than 30% and it is generaly larger between two south pro- vinces than between two north provinces.       These characteristics mentioned above are correlated with topography and climate, and they may be resulted from the diversification in geography and climatic influence for a long time.

基于压缩采样的模拟到信息转换的研究与实现

传统通信设备在处理宽带频谱稀疏信号时,面临高采样率、快处理速度等方面的困难。提出了一种基于压缩采样（Compressive Sensing,CS）的模拟到信息转换方法,解码端采用一定的算法对信号精确重构。仿真结果表明,与传统方法相比较,采样率降低了,并呈现出很好的恢复性能。     

Foetal Alcohol Spectrum Disorders: as prevalent as autism?

An examination of the literature on Foetal Alcohol Spectrum Disorders (FASD) and its relevance to the work of Educational Psychologists (EPs) suggested that the impact of FASD on EPs’ casework is an area which has been underexplored, and which merits further attention. A search of major electronic databases was conducted online; however no articles were found which specifically examined the role of the EP in connection with FASD. This is surprising as international research suggests that prevalence of FASD is as high as 1%, which implies that all schools are already dealing with the significant effects of FASD. It is suggested that EPs are well-placed to help schools clarify and meet the needs of children with FASD. Early identification may help reduce the risk of secondary disabilities and improve life outcomes for this group.     

An Integrative Review of Parenting Stress in Mothers of Children with Autism in Japan

Abstract

Parents of children with autism experience elevated stress that may be influenced by specific characteristics of the child and parent, including cultural norms and beliefs about parenting. However, there is little research on families of children with autism from cultural perspectives. The purpose of this integrative review is to identify factors influencing parenting stress in mothers of children with autism in Japan. A final sample of 15 primary research articles (2000–2015) on parenting stress in mothers of Japanese children with autism was selected using several databases. The findings suggested that these mothers experience much greater parenting stress than mothers of typically developing children and children with other disabilities. Japanese mothers also demonstrate stress related to attachment difficulties, low parenting efficacy and lack of support, reflecting Japanese parenting styles and gender ideology. Parent-directed and culturally calibrated interventions are needed to support parents of children with autism, especially cultural minority parents.
