Libraries and Spatial Literacy: Toward Next-Generation Education     

Benjamin D. Branch 《College & Undergraduate Libraries》2014,21(1):109-114

The role of the library is to assist citizens in skills development critical to national interest and empowerment as literacy ambassadors, in general. Specifically, the work by the Federal Geographic Data Committee (1994) indicates that spatial literacy is for every citizen and not just a set of workforce specialists. Hence, the use of maps in decision making and problem solving will become fundamental to all professions, including library professionals. Thus, a spatial literacy awareness and rationale for such as standard job ability is discussed as a future librarian workforce proficiency and knowledge transfer medium.  相似文献

A teacher’s journey: a first-person account of how a gay,Cambodian refugee navigated myriad barriers to become educated in the United States     

Kosal Sam 《International journal of qualitative studies in education》2013,26(6):714-729

Educational institutions, like most social service organizations, need to recognize intersectionality and complexity and move away from monolithic conceptions of homelessness – if they recognize homelessness at all. This first person account of a gay, Cambodian refugee illustrates the enormous complexity schools face in forming institutional responses for the needs of homeless, highly mobile, and economically displaced children and youth. This article demonstrates an effort to avoid reductionist definitions of homelessness and to include experiential representations of humans living at the margins (under the 5th Avenues of the world, in central parks, in downtown shelters, outside of the ethical and systemic “home” of current ideologies and social orders, under the politics of HIV in Africa, as refugees and as those “othered” by dominant social narratives). The research takes place in the context of the At Home At School program at Washington State University.  相似文献   

Impacts of social economic status on higher education opportunity and graduate employment in China     

Dong-mao Wen 《Frontiers of Education in China》2006,1(3):426-438

Based on a nation-wide survey of higher education graduates, this paper analyzes the impact of family background, using paternal occupation and education as indicators, on their scores in the National College Entrance Examination, the level and type of higher education institutions they attend, their employment after graduation, and the income they receive from their first job. It has been found that there are wide disparities among students with different family backgrounds in both access to higher education and their potential employment in China nowadays. This paper also studies how those influences happen. __________ Translated from Peking University Education Review, 2005 July (3)  相似文献

单核细胞增多性李斯特菌RsbR抗酸应激机制（英文）     

Ke He  Yong-Ping Xin  Ying Shan  Xian Zhang  Hou-Hui Song  Wei-Huan Fang 《Journal of Zhejiang University. Science. B》2019,(8):660-669

目的:探明单增李斯特菌RsbR的两个保守磷酸化位点是否影响SigB(sigmaB)的表达.创新点:解析了RsbR在单增李斯特菌中SigB网络调控中的作用.方法:通过基因缺失、定点突变和回补技术构建rsbR基因缺失株、回补株和回补突变菌株,进行酸应激条件下的生长能力和强酸条件下的存活能力试验,并检测在酸应激下菌株中的SigB基因和蛋白表达的改变情况.结论:RsbR缺失能够显著降低单增李斯特菌的抗酸应激能力和下调SigB表达,RsbR-175位点是SigB调控途径中RsbT释放的先决条件.  相似文献

重言管窥     

胡文群 《楚雄师范学院学报》2006,21(2):49-55

重言源远流长,应用广泛普遍。它结构独特,灵活多样;它短小凝炼,鲜明生动,往往起到画龙点睛的作用。通过重言来构词或构形,是汉语悠久的历史传统,也是具有鲜明民族特色的语汇、语法现象。在文学创作中,重言运用一直被当作主要的语言表现手法之一。重言的意义不仅表现在语言、文学上,而且渗进更广泛、深刻而根本的中国“社会传统”和“心理习惯”之中。它成为一种文化现象,对中国语言及文学、文化的历史、现实与未来产生重要的影响。  相似文献
