Previous studies have shown that weeding a library collection benefits patrons and increases circulation rates. However, the time required to review the collection and make weeding decisions presents a formidable obstacle. This study empirically evaluated methods for automatically classifying weeding candidates. A data set containing 80,346 items from a large-scale weeding project running from 2011 to 2014 at Wesleyan University was used to train six machine learning classifiers to predict a weeding decision of either ‘Keep’ or ‘Weed’ for each candidate. The study found statistically significant agreement (p?=?0.001) between classifier predictions and librarian judgments for all classifier types. The naive Bayes and linear support vector machine classifiers had the highest recall (fraction of items weeded by librarians that were identified by the algorithm), while the k-nearest-neighbor classifier had the highest precision (fraction of recommended candidates that librarians had chosen to weed). The variables found to be most relevant were: librarian and faculty votes for retention, item age, and the presence of copies in other libraries. 相似文献

For centuries, readers have added marginal commentary to books for a variety of personal and public purposes. Historians have mined the marginalia of important historical figures to observe their sometimes raw, immediate responses to texts. Now, reading and annotation practices are changing with the migration of content to electronic books. A survey of reader attitudes and behavior related to marginalia for print and electronic books reveals that the majority of readers write in their books and want e-readers to support this feature. However, many readers report that annotating electronic books is too difficult, time-consuming, or awkward with current technology. In addition, the way readers annotate books depends on whether they are reading for pleasure or for work or education. These findings can guide the development of future devices to better satisfy reader needs. 相似文献

Peer review of teaching is a collegial process designed to help academics reflect on and improve their teaching practice. Considerable research supports the value of peer review of teaching. However, uptake of voluntary programs is typically low. Few studies have examined the predictors of engagement in voluntary peer review. This study surveyed 221 (106 female, 115 male) academics in the first year of implementation of a peer review of a teaching program at a large dual-sector university. Results supported the impact of four key variables on willingness to engage in peer review of teaching: the perceived benefits of the program, an individual's perceived need for support around teaching, perceived drawbacks of the program and career-related benefits. Level of teaching experience was related to willingness to engage: staff with moderate levels of teaching experience were most willing to participate in the program. Limitations of the study are noted and recommendations for peer-review programs are provided. 相似文献

We elaborate a model of the incentives of scientists to perform activities of control and criticism when these activities, just like the production of novel findings, are costly, and we study the strategic interaction between these incentives. We then use the model to assess policies meant to enhance the reliability of scientific knowledge. We show that a certain fraction of low-quality science characterizes all the equilibria in the basic model. In fact, the absence of detected low-quality research can be interpreted as the lack of verification activities and thus as a potential limitation to the reliability of a field. Incentivizing incremental research and verification activities improves the expected quality of research; this effect, however, is contrasted by the incentives to free ride on performing verification if many scientists are involved, and may discourage scientists to undertake new research in the first place. Finally, softening incentives to publish does not enhance quality, although it increases the fraction of detected low-quality papers. We also advance empirical predictions and discuss the insights for firms and investors as they “scout” the scientific landscape. 相似文献

The purpose of this article is to review literature related to the impact of policy and legislation on Maori children with special needs. The historical perceptions of disability for Maori will be discussed and the impacts of western influences and policy will be reviewed. The article investigates relevant studies and literature, both national and international, previously carried out in these areas and other corresponding areas of research. It synthesises the main points relating to this review, enabling the reader to gain an awareness of a set of special needs and disability issues as they relate to a specific New Zealand population. These include concepts of disability, Maori and disability issues and special needs education and support provisions for Maori. 相似文献

ABSTRACTLearning a heritage language can be celebrated to enhance marginalized groups’ self-esteem, but a heritage can also encompass ideologies prevalent in the groups’ original homeland. Based on ethnographic fieldwork (2007–2011) at a weekend Japanese-language school in the United States, this article investigates how ideologies on race politics within a heritage language community’s homeland are reproduced or subverted through heritage language education. We analyze treatment of Korea–Japan power relations at school by focusing on the practice of guiding students (not) to shift their perspectives in three cases involving (a) discrimination against Resident Koreans in Japan, (b) gender-specific abortion in South Korea, and (c) South Korea and Japan’s dispute over possession of Tokdo/Takeshima. While social analyses of heritage language education tend to focus on a minority group’s place in mainstream society, this article suggests investigating the reproduction of ideologies from its homeland via heritage language education. 相似文献

Based on fieldwork at a weekend Japanese language school in the USA in 2007–2009, this article illustrates the ways in which different regimes of government arise from an activity depending on meanings individuals invest in it. We examine how two students in the same classroom experienced two different regimes of government: one of a low-track class for ‘native speakers’ and the other of a heritage language class for bilingual speakers. Building on Mitchell Dean's reworking of Foucault, we suggest a new approach to ethnographically studying governmentality which focuses on invested meanings. 相似文献
