从FRBR看编目条例及机读目录格式的变革路向   总被引：14，自引：1，他引：14  

王松林 《中国图书馆学报》2004,30(6)

在实体信息资源和网络信息资源并存的今天,编目对象应从文献单元和表达形式层次提高到表现方式和著作的层次,编目条例和机读目录格式也应作相应的变革。制订以表现方式以及著作实体为编目对象的编目条例是机读目录格式的变革路向。表1。图4。参考文献10。  相似文献

Assessing the Benefits of Content Notes Enhancements for Digital Audio Resources     

Laura N. Kirkland  Jean Wald 《Cataloging & classification quarterly》2018,56(4):287-297

Our library has previously investigated the potential impact the addition of contents notes on circulation. In a subsequent study, we found contents notes were the second metadata element most heavily linked to circulation (title was first). Since there has been a marked decline in the use of print resources at our library and a corresponding increase in digital resources, we wanted to know if the addition of contents notes to records for online streaming audio files would result in a similar increase in usage. After enhancing the records, we tracked usage for a period of three months.  相似文献   

基于信息使用环境理论的引用行为研究:参考文献分析的视角     

谢娟  成颖  孙建军  柯青 《中国图书馆学报》2018,44(5):59-75

目前,学术界多开展引用动机和引文功能的相关研究,但对于引用偏好等引用行为却关注较少。基于Taylor的信息使用环境理论,本研究采用参考文献分析方法,全面揭示了施引者引用行为的特征和影响因素。研究将信息使用环境理论中的前三类要素分别通过学者特征、组织环境及论题进行定义,采用参考文献分析法提取第四类要素;随机抽取论文样本,针对上述四类特征进行编码并通过统计分析探讨影响施引者引用行为的因素。研究发现:学者的年龄、性别、教育水平、学术年龄、职业角色、职称、所属机构的类型和层次以及所从事的研究主题和类型,都能对质量、语种、数量、信息资源类型、论文新旧的引用偏好产生显著影响。研究表明:信息使用环境理论和参考文献分析法在引用行为研究中具有适用性。表4。参考文献47。  相似文献   

Nurturing Authority     

Tanya Muscat 《Journalism Practice》2018,12(2):220-235

When considering the role of local journalism in a networked media environment, it is crucial to examine how audiences attribute news with the power to define social knowledge. In particular, television news programs need to appeal to audiences by reinforcing a sense of local journalistic authority to assert the parameters of who and what is worthy of coverage. This article presents the findings from interviews with a range of commercial television news viewers in Sydney, Australia. It positions viewership in the context of people’s wider engagement with news, and in relation to their interpersonal and digital social interactions. The paper argues that local audiences have conflicting attitudes to the role of television news, both contesting and re-inscribing the programs with the power to demarcate social, political, and cultural knowledge. It traces how local audiences challenge the ability of news to convey boundaries within the community through processes of exclusion, connecting the contestations to the lived experiences of the individuals. It identifies that television news programs nurture journalistic authority in terms of their local relevance, and it contributes insights on the significance of local news by engaging with the means by which audiences themselves attach social power to journalism.  相似文献   

Judges’ delivery of ground rules to child witnesses in Australian courts     

《Child abuse & neglect》2017

Ground rules directions are given to children in forensic interviews to explain what is expected of them, and to reduce their tendency to acquiesce to erroneous or incomprehensible questions. Ground rules may also be necessary when children provide testimony in court. Drawing on research conducted for the Australian Royal Commission into Institutional Responses to Child Sexual Abuse, the present study examined the use of ground rules directions delivered in court in 52 trials by 24 presiding judges in three jurisdictions to 57 child complainants (aged 7–17.5 years). Eleven categories of rules were identified. The number of words spoken to deliver each rule was counted, and grade-level readability scores were calculated as a proxy for the complexity of the ground rules. When judges asked comprehension or practice questions, the question types were coded. More than one third of the children (35%) received no ground rules directions from the judge; the remaining 65% received directions on an average of 3.5 types of ground rules out of a maximum of 11 types. While comprehension questions were common, practice questions were rare. Comprehension questions were most often presented in a yes/no format that implied the expected response, although this form of question is unlikely to provide an effective assessment of a child's comprehension. Neither the number of rules delivered nor the number of words used was related to children's age. Implications for children's court testimony are discussed.  相似文献   

Coordinating multiple representations of polynomials: What do patterns in students' solution strategies reveal?     

《Learning and Instruction》2017

We investigate the strategies used by 64 advanced secondary mathematics students to identify whether a given pair of polynomial representations (graphs, tables, or equations) corresponded to the same function on an assessment of coordinating representations. Participants also completed assessments of domain-related knowledge and background skills. Cluster analysis of strategies by representation pair revealed patterns in the participants' strategy use. Two clusters were identifiable on tasks that required matching equations to graphs and graphs to tables. We identified overlap between these two clusters, suggesting that while the representation pair influenced strategy choice, there was also a general distinction between students who used more and less sophisticated strategies. However, students who used more sophisticated coordination strategies were similar to the others on measures of domain-specific knowledge or background skills. We consider implications for future investigations testing interventions to promote coordinating representations.  相似文献
