The emerging creative practices of digital collections are increasing in prominence thanks to the access to, and appeal of, data visualizations. Interactive data visualizations, such as a map, timeline, chart, graph, or artist’s rendering of data, enable users to pursue their own research interests within a collection and participate in new areas of research. Use of these data visualizations enhances the scope of the collection and enables a modern and diverse thematic collection to emerge. This article considers the question: Does the addition of data visualizations affect how users participate with a research collection? Impacts on collection development, application of user-centered design, and analysis of users’ exploratory strategies are discussed. Examples of data visualizations used in digital humanities projects and digital collections are presented as case studies. 相似文献

The Occupy movement is said to represent a new generation of post-Seattle protests, driven by social networking, and breaking from organizing practices in previous eras. This study analyzes the Occupy Wellington protest to shed light on the role of protests in an era of digital media ubiquity. Based on the participant observation as well as 76 brief interviews, the study explores how activists used digital media, and examines the broader institutional logics that shaped organizing dynamics at the protest. The analysis discusses digital media saturation and the multiple institutional logics that activists drew from in their organizing, including collective action, connective action, aggregation, and networking. We argue that digital ubiquity marks the onset of a profound hybridity rather than an abrupt change in activist organizing practices. 相似文献

The recent convergence of digital cameras into mobile phones with Internet connectivity has provided the opportunity for individuals and organisations to adopt new image-making practices. The widespread use of photo-sharing and social networking platforms for sharing, accessing and storing digital photographs is presenting scholars in the social sciences with new areas of research that address the nature of digital photography. By examining the technological, social and cultural factors involved in contemporary image-making practices, scholars are presenting new concepts regarding the characteristics of digital photographs that impact archival activities aimed at managing and preserving trustworthy digital records. This article identifies and discusses the key concepts emerging from social science research on digital photography that are most relevant to the archival field. Analysis of the findings of these studies suggests that new technologies and social practices are changing how people use digital photographs and their expectations of permanence. Therefore, archivists need to be engaged in interdisciplinary discussions regarding the evolution of photographic practices and emerging characteristics of digital photographs in order to anticipate the management and preservation activities required to protect contemporary visual records for future use. 相似文献

Investigating task performance of probabilistic topic models: an empirical study of PLSA and LDA 总被引：2，自引：0，他引：2
Probabilistic topic models have recently attracted much attention because of their successful applications in many text mining
tasks such as retrieval, summarization, categorization, and clustering. Although many existing studies have reported promising
performance of these topic models, none of the work has systematically investigated the task performance of topic models;
as a result, some critical questions that may affect the performance of all applications of topic models are mostly unanswered,
particularly how to choose between competing models, how multiple local maxima affect task performance, and how to set parameters
in topic models. In this paper, we address these questions by conducting a systematic investigation of two representative
probabilistic topic models, probabilistic latent semantic analysis (PLSA) and Latent Dirichlet Allocation (LDA), using three
representative text mining tasks, including document clustering, text categorization, and ad-hoc retrieval. The analysis of
our experimental results provides deeper understanding of topic models and many useful insights about how to optimize the
performance of topic models for these typical tasks. The task-based evaluation framework is generalizable to other topic models
in the family of either PLSA or LDA. 相似文献

ABSTRACTChina’s distinct development of the Internet has provided religious populations within its mainland access, allowing them to create practices and resources related to the development of religion online. Yet this phenomenon has been understudied both within the current Chinese research on the Internet and international studies of digital religion online. This article provides an overview of digital religion in the Chinese context by identifying and exploring the main characteristics of Buddhism, Islam, and Protestantism manifest online. This is done by providing an overview of current research and profiling the development of different forms of digital religious expression found in China. Through this we show how the concept of digital religion is manifest in China and how this compares to Western understandings of such practices, and we highlight the unique characteristics defining the Chinese religious digital landscape. 相似文献

ABSTRACTThis article investigates how digital news editors perceive the uses and implications of audience analytics in contemporary digital newsrooms. Based on 21 interviews with digital news editors at 11 Belgian news organisations, including 7 national newspapers, one news magazine, one public and one commercial broadcaster, and one digital-born news medium, the study shows how audience analytics have become normalised in these digital newsrooms and how, in the perception of those who use them, tools for capturing audience behaviour data inform and shape their daily work practices and organisational strategies. Combining insights from literature with empirical findings, the study distinguishes six uses of audience analytics: Not only do analytics inform editorial decisions on (1) story placement, (2) story packaging, (3) story planning and (4) story imitation, but they can also serve as instruments for (5) performance evaluation and (6) audience conception. Overall, the digital news editors are convinced that audience analytics support rather than harm their journalism. 相似文献

This article describes a multicase field study of four public-facing Midwestern state agencies and how they organized the work of reviewing and approving textual content for publication on Internet Web sites. Drawing on field data and concepts from institutional theory, contingency theory, and organizational design, the paper generates a framework to document systematically the processes and practices involved in the review and approval of textual Web content. The framework is then used to compare textual content management practices across the four case sites and to begin to investigate the effects of variation in content management practices on characteristics of the available textual content. The article suggests how the framework could be used in future research to investigate how content practices affect content characteristics such as quality, quantity, and cost and to investigate how and why content management practices change over time. 相似文献

Journalists in the “new media” era confront important questions as to whether, or how, they adapt their professional practices to a new interactive on-line form that allows citizens to become involved in the news-making process. This paper seeks to re-establish the relevance of traditional journalism practices in the modern era and suggests that they will remain very much a part of the “new journalism” beyond the digital divide. It does so through examining how broadcast journalism interviews challenge authorities in the “public interest”, and suggests, in conclusion, that such practices remain undiminished by the technical, and accompanying social, changes that are driving the “new media”. 相似文献

Drawing inspiration from New Materialist philosopher Karen Barad's challenge to read “diffractively” by experimenting with different patterns of relationality, this article sets out a course of speculative inquiry inspired by the contemporary fascination with digital light‐based installations. Taking the UN's designation of 2015 as the “International Year of Light and Light‐based Technologies” as its point of departure, a subset of mediated environments are identified that transcend the distinction between physical and digital; materiality and immateriality; invisibility and presence. Employing new technologies to create deeply sensorial and highly participatory forms of aesthetic engagement, the selected examples offer a compelling indication of the post‐digital aesthetics that arise from the interrelationship of art, design and computation. Its investigation is structured as a montage of two parts: following an introduction that surveys an illustrative sub‐set of contemporary digital light‐based art works drawn from the 2014 INST‐INT conference, the second half of this text will speculate upon the “dynamic‐constructive” relationship between digital media and the form‐making processes associated with “practices of light” (Cubitt 2014 ). The implications of “post‐screen media” for curatorial practice is explored in relation to the mediating function played by modes of exhibition and other program architectures. 相似文献

Over the past decade, text recycling (TR; AKA ‘self‐plagiarism’) has become a visible and somewhat contentious practice, particularly in the realm of journal articles. While growing numbers of publishers are writing editorials and formulating guidelines on TR, little is known about how editors view the practice or how they respond to it. We present results from an interview‐based study of 21 North American journal editors from a broad range of academic disciplines. Our findings show that editors' beliefs and practices are quite individualized rather than being tied to disciplinary or other structural parameters. While none of our participants supported the use of large amounts of recycled material from one journal article to another, some editors were staunchly against any use of recycled material, while others were accepting of the practice in certain circumstances. Issues of originality, the challenges of rewriting text, the varied circulation of texts, and abiding by copyright law were prominent themes as editors discussed their approaches to TR. Overall, the interviews showed that many editors have not thought systematically about the practice of TR, and they sometimes have trouble aligning their beliefs and practices. 相似文献

ABSTRACTThis paper examines the impact of the digital transformation on broadcast practices from a producer/studio participant perspective with a focus on sports journalism online. More specifically, the study targets changes in sports talk and interaction as producers re-shape their communicative activities to fit audiences’ new contexts of reception. It discusses how these changes in practices relate to some of the fundamental assumptions in current broadcast talk theory. The textual studies are complemented by interviews with six prominent Swedish media industry representatives in order to shed light on their perceptions of the broadcast to online shift given their respective experiences. The results show how producers/participants adapt to a more casual and relaxed interactional style and tone online than in ordinary broadcasting. The studied sportscasts also largely abandon the traditional broadcast address, as expressed in direct discursive address and looks-to-camera, for an orientation to screen devices where social media active audiences are to be “found,” although still having a traditionally positioned audience to attend to. Although sociability is still the structural principle for producers’ interactional choices irrelevant of platform, the strategies of how to achieve it are changing due to the digital transformation. 相似文献

Describes the position claiming that the contemporary technological, sociopolitical, and socioeconomic environment gives us pause to consider the core theory and practices of bibliography, combining bibliography of the work (in library and information science), bibliography of the text (in textual studies and scholarly editing), and bibliography of the artifact (in book history and now digital forensics), and calls for collaborative multidisciplinary research at the intersection of these fields to ask, is there a new bibliography? 相似文献

ABSTRACTThis article explores best practices for supporting digital humanities (DH) activity and pedagogy in the undergraduate classroom on campuses without a DH center in the library. By examining specific aspects of librarians' curricular engagements, with a particular focus on reference and instructional activity, we discuss how reenvisioning these services aids in the development of effective support for both faculty and students engaged in DH. An included case study illustrates how redefining “traditional” librarian liaison roles and shifting expectations of faculty from one-shot instruction sessions to embedded librarianship models can be put into practice in undergraduate classrooms with a DH focus. The article concludes with a discussion of the librarian as digital humanist and how this role can positively impact undergraduate curricula. 相似文献

AbstractThis project examines the lightfastness of prints created with the most commonly used digital technologies (inkjet, color electrophotography, dye sublimation and digital press) along with prints created using traditional technologies (color photography, black-and-white electrophotography and offset lithography). The inclusion of traditional prints provides benchmarks for collection care professionals to better gauge the significance of the results. In this study, prints were subjected to two types of lighting used independently to simulate daylight through window glass and artificial indoor illumination. Five aspects of light damage were assessed: fade in the mid-tone neutral, fade in the darkest neutral tone, paper yellowing, changes in paper gloss and text readability. In general, digital prints were less sensitive to light than traditional prints; but each digital printing technology produced at least one sample that performed worse than its traditional benchmark in at least one of the aspects of light damage studied. Therefore, it is recommended that cultural heritage institutions strive to provide the most benign environment possible, taking display practices currently in use for traditional prints as a minimum starting point for the care of digital prints. Close monitoring for signs of change is also recommended. 相似文献

Academic libraries have long been seen as trustworthy stewards of user information, but in an increasingly dispersed digital environment, it has become challenging for libraries to provide completely safe online experiences. This essay, written from the perspective of a systems librarian at Boston College, suggests that academic libraries need to re-invent their privacy practices to better align with today's online reality. A collaborative, holistic approach is proposed: embedding privacy into how libraries collect, how they implement online access, how they teach, and how they advocate for privacy on their campuses. By taking a comprehensive look at privacy concerns across the library and the campus, and by developing practices grounded in the ethical underpinning of our profession, academic librarians can begin to earn back the trust of our users. 相似文献
