高校图书馆构建机构知识库的问题及对策分析   总被引：1，自引：0，他引：1  

王香莲 《台州学院学报》2008,30(2):79-81

机构知识库的建设现已倍受关注。高校图书馆在构建机构知识库过程中存在内容收集不完整、质量低下、版权问题、标准化问题及长期保存等问题。高校在构建机构知识库时应扩大宣传,争取相关部门及政策支持;不断丰富知识库内容;严把质量控制关;通过多途径解决版权问题;利用开源软件解决标准化问题;定期备份知识库中数据。  相似文献

Reading ability and memory span: Long-term memory contributions to span for good and poor readers     

McDougall  Siné J.P.  Donohoe  Rachael 《Reading and writing》2002,15(3-4):359-387

A number of studies have shown that childrenwith reading difficulties perform poorly ontests of verbal memory span. The extent towhich differences in memory span for good andpoor readers can be explained by differences ina long-term memory component to span as well asby differences in short-term memory processeswas investigated in this study. Memory spanand rehearsal rate were measured for high andlow frequency words and nonwords. Althoughmemory span performance for high frequencywords was comparable for all reading abilitygroups, good readers had better memory spanperformance for low frequency words. This wasattributable to differences in both short-termand long-term memory contributions to spanperformance. Differences between readingability groups also emerged when memory spanfor nonwords was measured. In this case,differences between groups also appeared to bethe result of difficulties which poor readersencountered in learning newphonologically-based materials (i.e. nonwords). The nature of the inter-relationships betweenmemory span, reading and measures ofphonological awareness are discussed in thelight of these findings.  相似文献   

“Blockers” do not block recall during tip-of-the-tongue states     

Nate Kornell  Janet Metcalfe 《Metacognition and Learning》2006,1(3):248-261

Tip-of-the-Tongue experiences (TOTs) are often accompanied by incorrect answers (blockers) that come to mind persistently and seem to block recall. According to the blocking hypothesis, blockers cause retrieval difficulty during TOTs. We predicted that delay would allow participants to forget their blockers, and thereby enhance TOT resolution. In Experiment 1 participants were asked trivia questions and then retested on the ones that elicited TOTs, either immediately or after a delay. There was an incubation effect overall, with greater TOT resolution after a delay than on an immediate test. Contrary to the blocking hypothesis, however, delay did not enhance resolution of blocked TOTs more than non-blocked TOTs. In Experiment 2, during the retest, participants were reminded of their previous blockers on some questions, but the reminders did not affect TOT resolution. These findings suggest that blockers may be a side effect, not a cause, of retrieval difficulty during TOTs. This paper is based on the first author’s Master’s thesis.  相似文献

Sanitizing the Struggle: Barack Obama,Selma, and Civil Rights Memory     

Theon E. Hill 《Communication quarterly》2017,65(3):354-376

In this article, I examine Barack Obama’s use of collective memory during his 2007 campaign speech in Selma, Alabama. Specifically, I argue that Obama appeals to collective memory to challenge the Black community’s relationship to the past. He reframed the memory of the Civil Rights Movement in a manner favorable to his political aspirations. While this frame was politically expedient, it weakened Black political agency. It robbed the Black community of crucial rhetorical resources used to challenge structural inequalities in society. This article offers insight into the complex relationship between metaphor and collective memory. Specifically, I interrogate the role of metaphor as a crucial site where public memory is formed, disrupted, and rearticulated. Furthermore, I consider the implications of his use of memory for the future of the Black freedom struggle.  相似文献

孙坦  陶俊 《图书馆建设》2010,(4)

机构仓储评价是指运用一定的方法对机构仓储从系统建设、内容组织、服务管理等方面进行多角度的评价,找出机构仓储在实践或服务管理方面的不足,以推动机构仓储向良性轨道发展的过程。其经过了评价先导期与评价实践期的发展历程,主要采用问卷调查法、观察研究法、层次分析法等研究方法。其评价指标为系统指标、内容指标和管理指标3个维度。评价内容包括相关者对机构仓储的认知态度及其存储行为评价、基于机构仓储的电子出版评价、机构仓储的自存档评价、机构仓储的系统化评价等。  相似文献
