Abstract

Academic library collections have been built and shaped by a focus on dominant voices and perspectives. In order for collections to reflect the value librarianship places on diversity as well as represent multiple perspectives and serve users of diverse backgrounds and identities, collections need to be assessed for coverage of content related to diversity. This article discusses the challenges inherent in engaging in such an assessment, discusses collection assessment methods, and describes an analysis performed on the Penn State University Libraries collections focused on lesbian, gay, bisexual, transgender, and queer content.  相似文献

中外情报学论文创新性特征研究   总被引:1,自引:0,他引:1  
[目的/意义] 综合运用定性与定量相结合的方法对近年中外情报学论文的创新性进行分析和对比,揭示情报学领域研究的创新性特征,发现领域学术论文中创新句内部的知识关系,进行更细粒度的论文创新性分析,为研究领域创新点深层次利用提供条件,同时丰富科技论文创新性监测的途径,促进科学研究创新。[方法/过程] 从句子级创新性识别出发,选取中英文各两种情报学期刊作为样本,采用信息抽取和机器学习的方法,将创新句的抽取从现有的摘要扩展到全文,充分利用句子结构和句法特征识别领域创新内容,探讨近年中外情报学论文在创新对象、主题、类别等方面的特征,并做对比分析,最后通过对自动分类的论文集合进行定性的内容分析,总结归纳出中外情报学论文创新的表达范式。[结果/结论] 从创新的表达来看,中外情报学论文创新句的分布情况基本一致,英文期刊论文创新的表达更丰富。从创新性特征来看,英文情报学期刊论文创新主题较集中,而中文主题多样和分散;具体方法的创新是近年情报学领域的创新热点,而在研究方法上创新不足;中英文情报学期刊论文的创新性特点都反映了应用研究、实证研究的成果较多,而理论创新推动缓慢的趋势。  相似文献

ABSTRACT

Libraries use surveys and other instruments to gather feedback from their users. However, with competition from many other campus entities requesting input, how can survey fatigue be avoided? To gather this feedback, the Social Sciences Reference Desk utilized a short, fun and easy method. Each week for 10 weeks during the fall semester of 2017, the reference assistants wrote a survey question on a whiteboard and provided sticky notes for patrons to write their answers. The survey provided valuable information about patrons’ needs and expectations. It also fostered changes that were easily implemented to improve the delivery of library services.  相似文献

Recommender Systems are currently highly relevant for helping users deal with the information overload they suffer from the large volume of data on the web, and automatically suggest the most appropriate items that meet users needs. However, in cases in which a user is new to Recommender System, the system cannot recommend items that are relevant to her/him because of lack of previous information about the user and/or the user-item rating history that helps to determine the users preferences. This problem is known as cold-start, which remains open because it does not have a final solution. Social networks have been employed as a good source of information to determine users preferences to mitigate the cold-start problem. This paper presents the results of a Systematic Literature Review on Collaborative Filtering-based Recommender System that uses social network data to mitigate the cold-start problem. This Systematic Literature Review compiled the papers published between 2011–2017, to select the most recent studies in the area. Each selected paper was evaluated and classified according to the depth which social networks used to mitigate the cold-start problem. The final results show that there are several publications that use the information of the social networks within the Recommender System; however, few research papers currently use this data to mitigate the cold-start problem.  相似文献

Assessment is a crucial part of degree programmes in higher education. While previous research has been primarily concerned with PhD thesis assessment practice in western countries, this article considers the focus and assessment criteria of 40 examiner reports on master’s dissertations in translation studies at a Chinese university. The results indicate that these examiners structured their reports in four rhetorical moves: ‘preparing the candidate for a decision’, ‘expressing an evaluation’, ‘conveying the decision’, and ‘making recommendations’. These examiners appeared to place more emphasis on the expression of ideas, rather than on the accuracy and originality of those ideas. They apparently adopted flexible working criteria, assessing the dissertations based on institutional requirements and on their own experience. This article concludes with a discussion of implications for dissertation writing.  相似文献

Christer Ekholm's point of departure in this article is Gert J. J. Biesta's call for a new pedagogical attitude that takes a stand against the current trend in education. At present, the dominant approach is to make what we do in school into something wholly predictable, measurable, and assessable, which (as Biesta argues) misses important aspects of what education actually is or should be. One such aspect has to do with “subjectification,” that is, events where someone makes an appeal to me, singles me out in my uniqueness, and makes me ethically responsible to the other one before me. What role can literary education play in facilitating such events? What kind of reading strategies should be promoted with the aim of such an ambition? On the basis of a critical analysis of the discursive construction of an opposition between reading as engagement and reading as distance, Ekholm argues that the answer to these questions is to be found in an alternative literature didactics, where the work of fiction is understood not as text, but as utterance; not as something written, but as writing; perhaps even, not in terms of object(ification), but of subject(ification)?  相似文献

ABSTRACT

This article explores the experiences of a group of established academic staff in New Zealand and the UK, as they undertake a doctorate in their home institutions. Our interest is in how individuals negotiate this dual status from a cultural-historical activity theory (CHAT) stance that explores how rules, tools, community and divisions of labour, and interacting activity systems, shape doctoral experiences. The focus in this article, having analysed their detailed narrative accounts, is on how academics experience three interdependent activity systems: those surrounding the thesis, the institutional context, and the home-life spheres. Issues related to time, workload and supervision issues, variability in collegial support and impact on personal priorities and time emerged. There is a range of particularities – from easy access to resources/supervisors to inflexible institutional regulations – applicable to this group of doctoral candidates. Negotiating life as an academic with concurrent doctoral candidature provides positive outcomes in terms of teaching, research confidence and general personal and professional development. However, a range of difficulties can also be encountered, particularly in relation to personal and professional relationships, and workload management.  相似文献

Given the history of caste politics in India, it is not surprising that the socially marginalized students face discrimination, especially after the introduction of the reservation policy (affirmative action) in educational institutes. Our qualitative study, informed by Meyer’s Minority Stress model, analysed in-depth interviews with 30 undergraduate students, 3 faculty members, and 4 administrative officials at a premier Indian university to examine the psychological wellbeing of the reserved category students. We analysed how the discrimination processes contributed to students’ poor academic performance, low self-esteem, and weak motivation. Student group affiliations and university resources created a supportive environment for the socially marginalized, despite a small risk of stigmatization due to enrolment in a few campus support-programs. Moreover, there existed a palpable frustration among the socially privileged students, resulting in discriminatory attitudes against reserved categories but not “lower” caste. Our findings call for the attention of college administrators, policymakers, and the society at large to ensure that well-intended social justice policies are efficiently implemented, to deliver justice to the underprivileged students of India.  相似文献
