浅谈地理信息系统(GIS)在水土流失中的应用领域   总被引：3，自引：0，他引：3  

胡良军 《绥化学院学报》2004,24(2):138-140

GIS是现代地理科学与空间信息科学相结合的产物,是现代地学领域十分重要的一门分析和应用工具。水土流失是地学与生态学领域多门学科的交叉学科,对空间信息的依赖性很强。本文介绍了GIS的概况,就水土流失的学科特点论述了适于GIS应用的若干领域,并对今后GIS在水土流失学科中的可能应用领域进行了探讨。  相似文献   

Peer perceptions of students receiving pull-out services in elementary school: A multi-age study     

Katherine K. Rose  Denaye Barahona  Joel Muro 《International Journal of Inclusive Education》2017,21(4):376-388

This study examined the peer nominations of 213 children in Kindergarten (90), 3rd grade (58), and 5th grade (65) to examine their perceptions of peers who received pull-out services for unique needs. Using Coie, Dodge, and Coppotelli’s[1982. “Dimensions and Types of Social Status: A Cross-age Perspective.” Developmental Psychology 18 (4): 557–570] protocol for assessing sociometric status in children, the results revealed that peer perceptions of most liked (ML) and least liked (LL) in the classroom were associated with pull-out status, with those students who did not receive pull-out services receiving more nominations as ML than their peers who did leave the classroom for pull-out services. Social impact scores for children who received pull-out services were not significantly different from those of children who did not receive pull-out services, but significant differences were revealed for social preference scores. Implications and avenues for future research are discussed.  相似文献   

在线实践社区中教师同伴互助活动的可视化     

李胜波  李爽  孙洪涛 《现代远距离教育》2011,(2):71-75

教师同伴互助活动的可视化有助于设计者对在线实践社区功能的反思和更精致设计的决策,对于参与在线实践社区同伴互助活动的教师而言,有利于识别教师同伴互助的行为模式、增加社区感、增强社会存在感、吸引教师的专注力和个人行为的反思与行动。对于研究的本身,为进一步的教师同伴互助行为的预测和挖掘奠定了基础。本文的目标是探究教师同伴互助活动可视化的思路、技术和方法。  相似文献

浅析学衡派“道德教化”思想的产生根源与理论得失     

韩建磊 《宜春学院学报》2011,33(10)

学衡派把中国近代危机归结于道德危机,提倡“道德教化”以挽救民族。“道德教化”思想的产生有其现实基础——功利主义盛行;亦有理论依据——人性二元论。“道德教化”思想呈现出明显的道德理想主义特征,却又点出了自我约束的必要性。  相似文献

《每周评论》对1919年南北和议的关注——兼论陈独秀的政治思想     

徐基中 《安庆师范学院学报(社会科学版)》2011,30(10):61-65

《每周评论》是陈独秀、李大钊等《新青年》同人专为批评时事、发表政见、策动政治革新而创办的小型时政周刊。《每周评论》同人对1919年南北和议持怀疑态度,不相信它能够解决中国的根本问题,而视之为南北特殊势力的＂分赃会议＂,同时亦可窥见这一时期陈独秀思想转变的痕迹。  相似文献

从词汇角度分析小说风格翻译——以《苔丝》三个中译本为例     

田绮 《海外英语》2015,(9):131-132

该文试图从词汇角度分析托马斯·哈代所著《苔丝》的风格翻译,三个中译本的作者分别是张谷若、孙法理和吴笛。从典故和方言翻译的层面,通过文本材料比较三个中译本在词汇方面的异同,作者发现,在小说风格翻译实践中,有些译者在翻译过程中忽视了带有文体价值的词汇的文体标记,故而译本未能忠实反映原文风格。通过对比分析,作者认为,张译在传达原作的典故文化方面更胜一筹,而吴译在方言翻译方面更忠实于原作的语言风格。  相似文献   

Peer victimization,deviant peer affiliation and impulsivity: Predicting adolescent problem behaviors     

《Child abuse & neglect》2016

Abundant evidence has demonstrated an association between peer victimization and adolescent problem behaviors. However, there is a large gap in knowledge about the potential mediators that associate peer victimization with problem behaviors and the potential moderators that exacerbate or buffer this association. The current study examined whether deviant peer affiliation mediated the association between peer victimization and problem behaviors and whether the direct and indirect associations were moderated by impulsivity. A sample of 1401 adolescents (50.1% boys, 11–14 years old) completed anonymous questionnaires regarding peer victimization, impulsivity, deviant peer affiliation, and problem behaviors. Gender, age and socioeconomic status (SES) were controlled for in the analyses. Structural equation models showed that peer victimization was significantly associated with more problem behaviors, and this association was mediated by deviant peer affiliation. Impulsivity moderated both the direct association (peer victimization → problem behaviors) and the second stage of the indirect path (deviant peer affiliation → problem behaviors). Specifically, these associations were especially stronger for adolescents with higher impulsivity. Identifying the processes by which peer victimization is associated with adolescent problem behaviors has important implications for an integrative framework of theory and prevention.  相似文献
