A focus on quality--the library's role in occurrence screening     

Howell PB  Jones CJ 《Medical reference services quarterly》1993,12(2):83-89

One of the highest priorities in today's hospitals is the provision of quality care to patients. The medical librarian has an increased responsibility to furnish quality information to the medical staff. Traditional methods of reference service continue to work well, but it is increasingly important for librarians to become more directly involved in hospital quality assurance (QA) activities. Occurrence screening is one system of QA where the librarian can make a difference.  相似文献

Effects of Mass and Interpersonal Communication on Breast Cancer Screening: Advancing Agenda-Setting Theory in Health Contexts     

Karyn Ogata Jones  Bryan E. Denham  Jeffrey K. Springston 《Journal of Applied Communication Research》2006,34(1):94-113

Drawing on components of agenda-setting theory and the two-step flow of information from mass media to news audiences, this study examines the effects of mass and interpersonal communication on breast cancer screening practices among college- and middle-aged women (n = 284). We theorized that screening behaviors among younger women would be influenced more by interpersonal sources of information while screening among middle-aged women would be more influenced by exposure to mass-mediated information. Findings supported anticipated patterns, revealing important and varying roles for both mass and interpersonal communication in the health behaviors of women. Implications for health practitioners and campaign planners, as well as recommendations for future research, are discussed.  相似文献

Mandatory Student Fees and the Academic Library     

Jennifer L. Jones 《图书馆管理杂志》2018,58(1):54-64

As academic libraries' budgets remain flat while their expenditures rise, library leaders must seek out alternative sources of funding. One option is a mandatory student fee dedicated to the library. This article presents the results of a survey of 152 deans and directors of public R1 and R2 research universities that were asked whether their libraries benefit from mandatory student fees. While a library-specific fee is unusual, nearly half of responding libraries are eligible to receive some portion of another mandatory student fee. Study results can serve as evidence for libraries preparing to make a case for the significant, positive impact possible through even a modest library fee.  相似文献   

Bringing the Law to the Library: The Importance of Librarian Mediation in Access to Justice Services     

Yolanda Patrice Jones 《Legal Reference Services Quarterly》2018,37(1):11-37

Library access to justice programs and services help people who need legal information and who cannot afford an attorney. Librarian mediation is a critical component in the provision of access to justice services. However, the value of library mediation, or assistance with using library resources, is often unrecognized, particularly where members of the public are trying to access electronic legal information sources, online legal forms, and other law technologies. This article will explore the role of librarians in providing access to justice services from the perspective of the work of Richard Susskind, which emphasizes technological approaches to providing legal services. While there is a place for technology in access to justice services, there is also a valuable role that librarians play in contributing to access to justice.  相似文献   

Retrieving and classifying instances of source code plagiarism     

Debasis?GangulyEmail authorView author&#;s OrcID profile  Gareth?J.?F.?Jones  Aarón?Ramírez-de-la-Cruz  Gabriela?Ramírez-de-la-Rosa  Esaú?Villatoro-Tello 《Information Retrieval》2018,21(1):1-23

Automatic detection of source code plagiarism is an important research field for both the commercial software industry and within the research community. Existing methods of plagiarism detection primarily involve exhaustive pairwise document comparison, which does not scale well for large software collections. To achieve scalability, we approach the problem from an information retrieval (IR) perspective. We retrieve a ranked list of candidate documents in response to a pseudo-query representation constructed from each source code document in the collection. The challenge in source code document retrieval is that the standard bag-of-words (BoW) representation model for such documents is likely to result in many false positives being retrieved, because of the use of identical programming language specific constructs and keywords. To address this problem, we make use of an abstract syntax tree (AST) representation of the source code documents. While the IR approach is efficient, it is essentially unsupervised in nature. To further improve its effectiveness, we apply a supervised classifier (pre-trained with features extracted from sample plagiarized source code pairs) on the top ranked retrieved documents. We report experiments on the SOCO-2014 dataset comprising 12K Java source files with almost 1M lines of code. Our experiments confirm that the AST based approach produces significantly better retrieval effectiveness than a standard BoW representation, i.e., the AST based approach is able to identify a higher number of plagiarized source code documents at top ranks in response to a query source code document. The supervised classifier, trained on features extracted from sample plagiarized source code pairs, is shown to effectively filter and thus further improve the ranked list of retrieved candidate plagiarized documents.  相似文献   

Back to the Future     

Stephen Jukes 《Journalism Practice》2018,12(8):1029-1038

The emergence of “fake news” during the Brexit referendum and Trump election campaign sent news organisations scurrying to establish teams of journalists to debunk deliberately misleading stories and verify facts. This paper examines steps to counter false stories and asks whether normative values of objectivity are about to enjoy a comeback. Typical markers of objectivity (freedom from bias, detachment and fact-based reporting) date back to the nineteenth century and, despite being ingrained in the Anglo-American news culture, have always been subject to challenge. Recently, the growth of partisan and populist media has illustrated deep distrust in traditional news outlets and is questioning whether it is time to jettison objectivity. But are we experiencing a backlash? Through interviews with senior UK-based journalists at legacy news organisations and analysis of editorial policy statements prompted by a UK parliamentary inquiry, the paper explores how fake news is rekindling debate about objectivity and its potential to make quality journalism stand out. It argues that legacy news organisations in the United Kingdom have seized the opportunity to highlight the value of normative practices that draw on familiar components of the objectivity paradigm. But few have the financial strength to bolster the rhetoric with additional editorial resources.  相似文献   

Why Use Multiple Representations in the Mathematics Classroom? Views of English and German Preservice Teachers     

Dreher  Anika  Kuntze  Sebastian  Lerman  Stephen 《International Journal of Science and Mathematics Education》2015,14(2):363-382

Dealing with multiple representations and their connections plays a key role for learners to build up conceptual knowledge in the mathematics classroom. Hence, professional knowledge and views of mathematics teachers regarding the use of multiple representations certainly merit attention. In particular, investigating such views of preservice teachers affords identifying corresponding needs for teacher education. However, specific empirical research is scarce. Taking into account the possible role of culture, this study consequently focuses on views about using multiple representations held by more than 100 English and more than 200 German preservice teachers. The results indicate that there are culture-dependent aspects of preservice teachers’ views, but also that there are common needs for professional development.
