This study compares the radio industry's use of interactivity to that of other traditional media on the Web such as newspapers and television stations, along the dimensions of audience-oriented interactivity and source-oriented interactivity. A content analysis of 112 traditional radio station Web sites, 282 traditional newspaper Web sites, and 128 traditional television station Web sites found that traditional radio station Web sites provided more audience-oriented interactivity compared to other traditional media Web sites, and traditional newspaper Web sites offered the most source-oriented interactivity. A general conclusion of this study is that although traditional radio stations were more likely to transmit live and archived sound than other media, all traditional media Web sites have held back from developing interactivity beyond e-mail, and have limited the transmission of streaming media, as well as archived audio and video content. 相似文献

ABSTRACTThis study explores the current status and features of Pakistan's academic library Web sites. A checklist describing features and content was prepared based on a review of the literature related to academic libraries’ Web sites. Then, all 85 library Web sites of Pakistani universities and degree-awarding institutions recognized by the Higher Education Commission (HEC) of Pakistan were surveyed and analyzed using the checklist. Interviews with library professionals were conducted to learn more about the problems and issues with building and maintaining library Web sites. Results indicate that Pakistani academic library Web sites have effective features such as contrasting color schemes, easily readable text, minimal use of horizontal scrolling, and English-language text. Staff information, OPACs, and navigation features are also widely found on the Web sites. Features found less frequently include the use of Web 2.0 technologies, Web site aid tools, information about library buildings, and general library information. By offering information about the status of Pakistani academic library Web sites, the study can serve as a foundation for discussion between libraries and other parts of the university, as well as a benchmark for evaluating the progress of academic library Web sites in Pakistan 相似文献

The digital transformation of journalism enables new modes of interactivity with the news. While user comments are nearly ubiquitous across news Web sites, there is little understanding about how to improve the quality of discussion spaces that many characterize as hostile and vitriolic. This study uses a keyword content analysis of user comments across 20 news Web sites to understand the organizational policies that encourage more productive dialogue. The findings show that specific policies regarding user registration, moderation of comments, and reputation management systems are effective facilitators of civil discussion. 相似文献

Anchor texts complement Web page content and have been used extensively in commercial Web search engines. Existing methods
for anchor text weighting rely on the hyperlink information which is created by page content editors. Since anchor texts are
created to help user browse the Web, browsing behavior of Web users may also provide useful or complementary information for
anchor text weighting. In this paper, we discuss the possibility and effectiveness of incorporating browsing activities of
Web users into anchor texts for Web search. We first make an analysis on the effectiveness of anchor texts with browsing activities.
And then we propose two new anchor models which incorporate browsing activities. To deal with the data sparseness problem
of user-clicked anchor texts, two features of user’s browsing behavior are explored and analyzed. Based on these features,
a smoothing method for the new anchor models is proposed. Experimental results show that by incorporating browsing activities
the new anchor models outperform the state-of-art anchor models which use only the hyperlink information. This study demonstrates
the benefits of Web browsing activities to affect anchor text weighting. 相似文献

This study reexamined the concept of interactivity and proposed that interactivity be defined as the extent to which the communicator and the audience respond to each other's communication need. Interactivity was construed as consisting of five dimensions: 1) playfulness, 2) choice, 3) connectedness, 4) information collection, and 5) reciprocal communication. Web sites for products, services, and retail outlets appeared to differ significantly in terms of connectedness, information collection, and reciprocal communication. 相似文献

Based on a survey of 419 industry professionals responsible for maintaining radio station Web sites and a content analysis of 900 radio station Web sites, this study provides an overview of the state of Web radio in the late 1990s. This study investigates the extent of Web radio, the range of content offered on radio station Web sites, the benefits realized as a result of having a Web site, and the problems encountered with Web sites, and makes recommendations based on the findings. A general conclusion of this study is that although the Web presents a wealth of exciting possibilities, most radio broadcasters are currently underutilizing the Web and their Web sites. 相似文献

Performative acts of reading in websites are defined by interactivity which constitutes a site of action and signs in cyberspace. The interactive potential in websites is further augmented through multimodal representations of content. Multimodality hinges on synaesthetic combinations of multiple modes such as orality, writing, visuality and sound. This paper seeks to examine the multimodal representations of discourses surrounding the news of death sentence awarded to four convicts involved in Delhi gang rape and murder of Nirbhaya in CNN IBN news website. Furthermore, it adopts an approach to locate affective forces that characterise the multimodal text concerning the macro-theme of the news through mediated discourses of affect. 相似文献

The federal government's war on terrorism has heightened understanding and appreciation of the many facets of electronic government. Electronic government is used as a resource in the war on terrorism, helping to prevent and prepare for attacks. It might also prove useful in recovering from attacks. Unfortunately, e-government itself is a likely target for terrorists. Cyber intrusions into government Web sites and damage to, or destruction of, infrastructure, whether a computer system or an electrical grid that supplies power, could impair e-government. E-government is also attractive as a potential target for the information it provides, information that enemies of the United States could use in identifying weaknesses and planning attacks. While the Bush Administration has developed a comprehensive policy, based on a market model, for facilitating the use and effectiveness of e-government, its approach to e-government security, particularly in the area of Web content, has been ad hoc. Soon after the September 11, 2001, attacks, federal agencies began scrubbing their Web sites, an effort that has implications for the notion, and practice, of having a well-informed citizenry. 相似文献

Usability testing is an important element when designing useful, usable academic library Web sites. Since 2001, members of the Florida International University Libraries Web team have worked toward establishing a process that identifies user needs through usability testing. Starting with the libraries’ first Web site redesign project in 2001, the team has taken an active part in improving Web site user experience. After engaging in multiple redesign efforts, the Web team has developed a process that supports awareness of user experience through continual usability testing and feedback gathering. This article presents strategies and practices to measure Web site user experience, including classic usability testing methods (e.g., card sorting activities, focus groups, and task-based user testing), as well as the team's latest effort to assess Web site analytics and content to identify Web site usage patterns and areas of concern. A history of the Florida International University Libraries’ Web site redesign process is presented to illustrate lessons learned and best practices to facilitate future redesign and testing efforts. Taking a longitudinal look at usability testing at one institution, the study aims to inform the development of an effective strategy for user research and content management. 相似文献

Considering radio as a social system for the production of culture and communication, and based on an overview of the Greek case, this article suggests a model for studying the potential of the Web casting radio compared with the traditional radio in various media environments. The model suggested includes eight dimensions: institutional framework, market structures and business models, content diversity, audience profile, interactivity, sociability, relations with the recording industry, and relations with major news media and organizations. The analysis shows that a complex approach is needed to explore the chances for the potential of the Web casting radio to be realized. 相似文献

Social networking on the Web has become very popular in recent years. Used by more than 950 million people worldwide, Facebook is one of the most popular of these services. One interesting aspect of Facebook is that users can converse through various formats, including wall posts, photographs, Web links, music, and video clips of stories and interests surrounding their daily lives. This phenomenon raises an important question for archivists in regard to personal history on the Web: What are the new ways that contemporary people document their life stories? This study looks at Facebook activities from the perspectives of personal documentation. Using an online survey, this study investigates how Facebook content presents users themselves and their everyday stories, whether they perceive their activities of using Facebook as personal documentation, and what factors influence such activities. The findings of this study show the current status of Facebook usage. Facebook content indeed indicates information of self-presentation and personal documentation of everyday lives of users. Attitudes about and activeness on Facebook are the major factors that influence self-presentation and personal documentation activities on Facebook. Generic external factors, such as personal archiving in general, do not show strong associations with personal documentation activities as factors. Based on this understanding, we discuss the roles of information professionals and cultural heritage institutions in dealing with a new type of personal record on the Web. 相似文献

Library 2.0 literature has described many of the possibilities Web 2.0 technologies offer to libraries. Case studies have assessed local use, but no studies have measured the Library 2.0 phenomenon by searching public social networking sites. This study used library-specific terms to search public social networking sites, blog search engines, and social bookmarking sites for activity associated with librarians and library users. Blog search data about the recentness of activity or the popularity of a blog post indicate that Library 2.0 technology has many early adopters but provides less evidence of sustained use. The results follow a curve resembling the 80/20 rule and also resemble Chris Anderson's “long tail” effect, in which very few authors create the vast amount of content. These exploratory results can be used as a starting point for future studies. Librarians who use tags to describe Web-based content might use these findings to select more effective tags. Librarians implementing a blog or a social networking presence might use this study to balance the benefits with the amount of work required to maintain an up-to-date presence. 相似文献

This research analyzed a dataset of academic libraries' posts on Facebook. It applied a text and data analytics approach to a dataset collected from the Facebook posts of academic libraries at the top 100 English-speaking universities, as listed by the 2014 Shanghai World University Rankings. The dataset is from a two-year posting history of 18,333 unique posts, 113,621 likes, and 3401 comments. Less than a quarter of the libraries had more than 2000 post-related likes, and only seven received more than 100 comments on their postings. Content analysis identified the most prevalent single word (unigrams), bigrams (two-word sequences), and trigrams (three-word sequences) in high and low engagement content. Semantic analysis identified the semantic categories for posts with high and low engagement. The findings can assist academic libraries in their social media strategies for engagement, marketing, and visibility. 相似文献

In designing digital literacy content for marginalized demographics, we need to garner local resources to structure engaging and meaningful media experiences. This paper examines the socio-cognitive implications of a novel edutainment product in rural India on learning, stemming from an e-development initiative funded by Hewlett-Packard. This product encapsulates a multiplicity of media forms: text, audio and visual, with social-awareness folk themes endemic to the locality. It uses the karaoke ‘same language subtitling’ feature that won the World Bank Development Marketplace Award in 2002 due to its simple yet innovative application that has proven to have an impact on reading skills. The product strives to combine cultural regeneration, value-based education, incidental literacy and language practice through entertainment. The paper investigates how this product addresses engagement and empowerment simultaneously, based on elements such as emotional appeal, multimodal stimulation, interactivity, contextual content and local representation. This is useful for practitioners and scholars interested in the design of novel edutainment content for international, underrepresented demographics. 相似文献
