The Information Nature of Culture     

A.?D.?UrsulEmail author 《Scientific and Technical Information Processing》2018,45(2):100-105

This paper explores the information nature of culture. It is represented as an extragenetic and nonorganizational information process and system. Information is regarded as a universal property of matter that is essentially associated with development processes and realizes various forms and ways of storage and circulation at various development stages of global evolution. The socio-cultural principle of exogenous accumulation, transmission, and transformation of information is analyzed in the context of the continuing growth of the information content of material systems on the superhighway of global-universal evolution. It is noted that the information concept of culture evolves into a new area of cultural studies, that is information and cultural studies, advancing our understanding of the nature of culture and cultural genesis.  相似文献   

Historical case study: A research strategy for diachronic analysis     

Michael M. Widdersheim 《Library & information science research》2018,40(2):144-152

History and case study are two diachronic research strategies commonly used to study political discourse as it relates to public libraries. Though suitable for some studies, these strategies are inexhaustive. A new, blended research strategy is therefore needed to accomplish what history and case study alone cannot. This hybrid strategy, historical case study, must analyze cases from the distant past to the present, using eclectic data sources, in order to produce both idiographic and nomothetic knowledge. To develop historical case study, the universal components of diachronic analysis are first identified. A general research design for historical case study is then introduced. Finally, historical case study is tested in an actual research project. Findings from this project reveal that historical case study is a successful diachronic research strategy. Historical case study is a new and valuable research design suitable for addressing questions related to change, continuity, development, and evolution.  相似文献   

A Model for Quantitatively Analyzing Representations of Social Class in Screen Media     

Elizabeth Behm-Morawitz  Brandon M. Miller  Jennifer Lewallen 《Communication Research Reports》2018,35(3):210-221

Content analyses of prime-time television provide a picture of predominant cultural stereotypes and social trends. The present research is a quantitative content analysis of social class in popular broadcast and cable television in the United States. This research advances scholarship by systematically analyzing character class in addition to more commonly examined variables such as race and gender. A model for the operationalization of class for quantitative content analyses of mediated texts is offered. This proof of concept study demonstrates the viability of studying media representations of class quantitatively to systematically document patterns of portrayal.  相似文献   

Diversity on U.S. Public and Commercial TV in Authorial and Executive-Produced Social-Issue Documentaries     

Caty Borum Chattoo  Patricia Aufderheide  Kenneth Merrill  Modupeola Oyebolu 《广播与电子媒介杂志》2018,62(3):495-513

Where are diverse makers and subjects most likely to be found in U.S. TV documentary? This study compares commercial and public TV series, and also anthology formats (“authorial” series) and executive-produced formats. A content analysis for characters and makers showed that public TV authorial series are more diverse than either commercial or other public TV series. Independent documentaries have diversity value both in commercial and public TV settings.  相似文献   

Preparing for Practice: Strengthening Third-Year Medical Students’ Awareness of Point-of-Care Resources     

Tamara M. Nelson 《Medical reference services quarterly》2018,37(3):312-318

This column describes the development and implementation of a responsive library course designed to train third-year medical students as they begin their clerkships. The course design consisted of a brief face-to-face introduction during third-year orientation and an online course developed in Canvas, an online learning management system. The objective of the course was to not only introduce students to the resources but also to teach them how to effectively use those resources at the point-of-care. Students evaluated the course to assess the overall effectiveness of the instruction. Course development and content, feedback provided by students, as well as suggestions for improvement are discussed.  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

Cultivating communities of care: A qualitative investigation of the communication of support among incarcerated women     

Courtney Hook  Patricia Geist-Martin 《传播与批判/文化研究》2018,15(2):127-143

In 2014, a female-only detention and re-entry facility was restructured to implement new rehabilitative philosophies rooted in strategies to prepare incarcerated women for successful transition into society. A specialized housing unit called incentive-based housing (IBH) was created within this facility to promote an environment of accountability and responsibility. Here, women are expected to be proactive in seeking and achieving successes through programming, all while offering support to one another. In this study, participant observations and interviews were used to understand how 12 incarcerated women living in IBH communicate support. This qualitative study revealed three forms of support being communicated: (a) accountability, (b) validation, and (c) compassion. This study also revealed forms of communication that complicate support, including (a) drama and (b) rivalry. Communication of support is important to consider as we devise new approaches to rehabilitation within America’s criminal justice system.  相似文献
