利用全息技术构建图书馆数字资源新的存储平台     

刘普 《现代情报》2006,26(4):93-95

存储技术和存储设备的建设是构造现代化数字图书馆的基础组成部分。全息存储是一种利用激光干涉原理将图文等信息记录在感光介质上的大容量信息存储技术，它可以在不改变激光波长的情况下，极大的提高存储密度。随着仝息存储技术和相关标准的不断发展和完善，这种存储解决方案将会给图书馆存储基础设施的建设带来极大的益处。  相似文献

组织即兴、组织学习和组织记忆三者关系的研究   总被引：1，自引：0，他引：1  

蒲明 《科学学与科学技术管理》2007,28(9):154-157

在回顾组织即兴、组织记忆和组织学习相关文献的基础上,指出现有文献只是研究了组织即兴与组织记忆,组织即兴与组织学习的两两关系,没能进一步探究组织即兴、组织学习和组织记忆三者之间的关系。因此,提出了组织即兴与组织学习和组织记忆三者之间的动态关系模型。  相似文献   

新时期档案机构参与非遗保护的反思与再定位     

赵跃 《档案学通讯》2020,(2):40-48

21世纪以来,在社会参与非遗保护的热潮中,档案学界对档案机构的参与寄予厚望,但本文通过文献调查发现,实践中档案机构的参与状况并不理想,呈现小规模和自发性的参与特点;参与方式虽体现出专业化优势,但存在较大的局限性;参与效果呈现边缘化和形式化窘境。作者认为缺乏动力、缺乏魄力、缺乏实力是造成档案机构参与状况不理想的主要原因。最后,文章提出在新时期档案机构应重新定位参与非遗保护的角色,把握文化治理趋势彰显档案馆的人文关怀,抓住记忆建构趋势开展非遗档案资源库建设,紧追人文研究趋势拓展非遗数字人文服务,重视文化服务趋势参与非遗专题资源整合共享,关注文化传播趋势加强非遗文化知识传播,正视文化传承趋势开展非遗档案知识服务。  相似文献   

我国档案社会记忆研究的文献计量及可视化分析     

李财富  靳文君 《山西档案》2020,(1):143-150

对档案学核心期刊中244篇档案社会记忆研究论文进行文献计量及双聚类分析,可以直观、科学地反映我国档案社会记忆研究的发展状况。我国档案社会记忆研究目前已趋于成熟发展阶段,研究主体呈现出多元化趋势,研究主题主要集中在后保管时代档案社会记忆价值构建、档案记忆和权力与身份认同的关系、非物质文化遗产及边缘弱势群体的档案记忆、数字档案记忆资源的整合和开发等方面。建议在档案社会记忆范式构建期继续深化理论研究深度,将档案社会记忆的学理性与应用性相结合,发挥理论研究的现实指导和发展预测功能。  相似文献   

Component skills of text comprehension in less competent Chinese comprehenders   总被引：1，自引：0，他引：1  

Leong CK  Hau KT  Tse SK  Loh KY 《Annals of dyslexia》2007,57(1):75-97

The present study examined the role of verbal working memory (memory span and tongue-twister), two-character Chinese pseudoword reading (two tasks), rapid automatized naming (RAN) (letters and numbers), and phonological segmentation (deletion of rimes and onsets) in inferential text comprehension in Chinese in 31 less competent comprehenders compared with 37 reading comprehension control students and 23 chronological age controls. It was hypothesized that the target students would perform poorly on these cognitive and linguistic tasks as compared with their controls. Furthermore, verbal working memory and pseudoword reading would explain a considerable amount of individual variation in Chinese text comprehension. RAN would have a nonsignificant role in text comprehension. Structural equation analyses and hierarchical multiple regression analyses generally upheld these hypotheses. Our findings support current literature of the role of verbal working memory in reading comprehension found in English. The results, however, suggest differential role of the constructs and the tasks in reading comprehension and provide some answers for comprehension impairment in Chinese students.  相似文献   

Phonological processing and emergent literacy in younger and older preschool children     

Anthony JL  Williams JM  McDonald R  Francis DJ 《Annals of dyslexia》2007,57(2):113-137

Phonological awareness, phonological memory, and phonological access to lexical storage play important roles in acquiring literacy. We examined the convergent, discriminant, and predictive validity of these phonological processing abilities (PPA) in 389 3-, 4-, and 5-year-old children. Confirmatory factor analysis supported the validity of each PPA as separate from general cognitive ability and separate from each other. Multigroup structural equation modeling (SEM) with mean structure demonstrated that older preschoolers have better developed latent PPA than younger preschoolers but that the structure of PPA is equivalent. RAN was found uniquely associated with letter knowledge and text discrimination in younger preschoolers, and PA was found uniquely associated with word reading skills in older preschoolers. Finally, general cognitive ability was only indirectly associated with emergent literacy via PPA. These results highlight the importance of PPA in the early literacy development of English-speaking preschool children.  相似文献

The Twelve Cranial Nerves of Christmas: Mnemonics,Rhyme, and Anatomy – Seeing the Lighter Side     

Claire F. Smith  Scott Border 《Anatomical sciences education》2019,12(6):673-677

Anatomy, has in history, been linked to helpful ways to remember structures, branches of nerves, structures passing through foramina, etc. Scalp is even a mnemonic in itself (S kin, C onnective tissue, A poneurosis, L oose areolar tissue, P ericranium). There has been concern by some educators that using mnemonics or rhymes promotes a surface approach to learning and is unhelpful in establishing long-term and meaningful deep learning. This article argues that mnemonics and rhyme can be used, in the appropriate way, at the right time, by students as an important learning strategy. That strategy can help lay a foundation of knowledge to be developed and later built upon, or simply recall information more easily. Mnemonics, like all information that is to be recalled, is consolidated by rehearsal. In examining the neuroanatomy of learning theories, it is therefore possible to suggest that when students begin to learn an area of anatomy, such as the cranial nerves, using a mnemonic or rhyme, it can help students remember the names and facilitate the engagement of the working memory processes assisting the student to build a construct for subsequent deeper layers of knowledge. Modern approaches to anatomy education involve a myriad of learning opportunities, but educators must assess the value of each one before recommending them to students. It appears that using mnemonics and rhyme is as valid today as it has been for centuries.  相似文献
