Automated Classification to Improve the Efficiency of Weeding Library Collections     

Kiri L. Wagstaff  Geoffrey Z. Liu 《The Journal of Academic Librarianship》2018,44(2):238-247

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   

英美两项高等教育系统职能分化政策的比较分析   总被引：1，自引：0，他引：1

Indigenizing Education and the Phenomenology of Place     

Justin Pack 《Educational theory》2019,69(5):603-613

In this essay Justin Pack responds to Vine Deloria, Jr., and Daniel Wildcat's call to “indigenize education” by exploring what that entails both in his own life and for his teaching. Recognizing the power of place in Native American metaphysics, epistemology, and ethics is essential to the project of indigenizing education, according to Pack. He recounts how reading Deloria and Wildcat's Power and Place: Indian Education in America as a graduate student radically changed his perception of and relation to place, instilling in him the insight that knowing the history of a place is key to gaining a sense of one's connection to place. This realization, in turn, influenced Pack's approach to teaching. He came to understand that passing his changed perception and experience of place along to his students helped their development of critical thinking skills by exposing them to a metaphysics radically different from Western epistemology and ethics and by opening a path for them to recover a deeper sense of what it means to be in a place. Ultimately, Pack's aim in the essay is to demonstrate the potential for teaching Native American philosophy to function as a disruptive force in the classroom.  相似文献   

Finding and explaining differences: A reply to Gudykunst and Hammer     

Richard L. Wiseman  Hiroko Abe 《Int J Intercult Relat》1984,8(1):11-16

A rejoinder to Gudykunst and Hammer's critique of a recent paper is presented. We argue that their position is based on two mutually exclusive propositions and cannot therefore be credible. We continue to maintain that the evidence on intercultural effectiveness shows both culture-general and culture-specific components.  相似文献

Population differences in constructive memory     

Daniel W. Kee  Susan Nakayama Siaw  Linda Carter 《Contemporary educational psychology》1985,10(3):268-274

An experiment was conducted to evaluate constructive memory in fourth-grade low-SES black and middle-SES white children. The children were read nine short passages; each passage was composed of two premise statements and a filler sentence. The children were tested by a recognition procedure. Thirty-six test sentences were presented randomly. Four sentences were associated with each passage (true premise, false premise, true inference, and false inference). Subjects were asked to make yes/no recognition decisions based on whether the test sentence was identical to a sentence presented at study. Middle-SES white children made few errors, except to true inference test sentences. This pattern of performance is consistent with the constructive view of memory. Low-SES black children also had a high error rate to true inference items. However, this outcome may not reflect constructive memory because they also had a high error rate to some of the other types of test sentences.  相似文献   

Intercultural communication for health personnel     

Elizabeth Berry  Joan B. Kessler  John T. Fodor 《Int J Intercult Relat》1983,7(4):377-392

In order to develop successful health care delivery systems, both in the United States and abroad, health service workers need to understand various cultural orientations and to communicate effectively within the cultures. The authors discuss the cultural implications of health problems in three countries, the need for training health science professionals in intercultural communication, and describe an intercultural communication course designed especially for health science students at California State University, Northridge.  相似文献   

Phenomenology and hermeneutics: Evolving approaches to the study of intercultural and international communication     

Fred L. Casmir 《Int J Intercult Relat》1983,7(3):309-324

The thought models and theories of many individuals and disciplines have contributed to the study of human communication. In recent years scholars have become increasingly aware of the fact that methodologies superimposed upon the actual event of human communication have significantly shaped our perceptions of these events. Going beyond methodological approaches or quarrels, a phenomenological basis requires direct encounter with the event and an attempt to let methodology evolve out of that direct encounter, rather than attempting a so-called objective approach. Self, experience, values, and human relationships are of primary concern to the phenomenologist who sees meaning and interpretation as a unitary concept. Phenomenology thus concerns itself with understanding, and the bases for such understanding, rather than with the mere application of methodology. At the same time, phenomenology by its very approach, concerns itself not merely with the discovery of some abstract truth, but must be deeply concerned also with the improvement of the human condition founded in conscious experience. Behavior and meaning thus become conjoined. The ultimate aim of phenomenological studies becomes a concern with the ontological as well as the epistemological bases of human understanding.  相似文献
