Observations of the contemporary news media environment often revolve around the topics of ideological polarization and blurred boundaries between mass and interpersonal communication. This study explores these topics through a focus on the association between ideologically oriented online news use, commenting on online news, and political participation. We hypothesize that both ideological online news use generally and proattitudinal online news use are positively related to political participation and that online news commenting creates “differential gains” by augmenting these relationships. Yet we also hypothesize that counterattitudinal online news use is negatively related to political participation and that online news commenting creates “differential losses” by exacerbating this relationship. Analyses of two independently collected and nationally representative surveys found that frequent ideological online news use, proattitudinal online news use, and commenting are all positively related to political participation. We found no evidence for differential gains as a result of online commenting but only for differential losses—counterattitudinal online news use interacts with commenting to create a negative relationship with political participation. 相似文献

Current online stores suffer from a cardinal problem. There are too many products to offer, and customers find themselves lost due to the vast selection. As opposed to traditional stores, there is little or no guidance that helps the customers as they search. In this paper, we propose a new approach for designing a successful personalized online store enabling the successful searching of customers in the store. This approach is based on algorithms commonly used in recommendation systems, but which are rarely used for searches in online stores. We employ this approach for both keyword and browse searches, and present an implementation of this approach. We compared several search guide algorithms experimentally, and the experiments' results show that the suggested algorithms are applicable to the domain of online stores. 相似文献

PURPOSE: The research sought to determine the impact of online journals on the use of print journals and interlibrary loan (ILL). SETTING: The Library of the Health Sciences-Peoria is a regional site of the University of Illinois at Chicago (UIC) Library with a print journal collection of approximately 400 titles. Since 1999, UIC site licenses have given students and faculty affiliated with UIC-Peoria access to more than 4,000 online full-text journal titles through the Internet. METHODOLOGY: The Library of the Health Sciences-Peoria has conducted a journal-use study over an extended period of time. The information collected from this study was used to assess the impact of 104 online journals, added to the collection in January 1999, on the use of print journals. RESULTS: Results of the statistical analysis showed print journal usage decreased significantly since the introduction of online journals (F(1,147) = 12.10, P < 0.001). This decrease occurred regardless of whether a journal was available only in print or both online and in print. Interlibrary loan requests have also significantly decreased since the introduction of online journals (F(2,30) = 4.46, P < 0.02). CONCLUSIONS: The decrease in use of the print collection suggests that many patrons prefer to access journals online. The negative impact the online journals have had on the use of the journal titles available only in print suggests users may be compromising quality for convenience when selecting journal articles. Possible implications for collection development are discussed. 相似文献

Researchers have just begun to acknowledge the importance of incorporating the component of human-computer interaction in the design of online information systems. With the advent of interactive computer systems designed for direct use by the general public, the need has become apparent to design "friendly" user interfaces. In this regard, online public access calalogs, OPACs, are no exception. Recent research studies of OPAC users have found that (i) subject access in online catalogs is coming to be valued at least as much as known item access, and that (ii) OPAC users have a number of serious difficulties with subject searching. Consequently, we need to understand what characterizes human-computer compatibility and to examine various means of assisting the OPAC user at the heart of online searching tasks. 相似文献

Several techniques are available to measure an individual's selective exposure to online content, but only a few investigations have examined actual selective exposure to online stimuli experimentally generated and manipulated. We discuss a successfully implemented approach specifically developed for this purpose. By providing researchers with a combined record of observational selective exposure data and self-report data, the approach we describe here offers selective exposure investigators the opportunity to examine the joint impact of media content features and media user characteristics on selective exposure. Its theoretical and methodological foundations, applicability for a wide array of research questions, and the limitations of this approach are discussed. 相似文献

While shopping is a practical act of purchasing products and services, it is also recognised as a recreational activity with experiential dimensions. Online shopping is no exception. This study focuses on the experiential dimensions of online shopping by conducting an ethnographic analysis of online store websites to identify website features which can provide online shoppers with sensory stimulation and social gains, and invoke affective responses. Websites of four product and service categories were studied: books, CDs, travel‐related services, and apparel. The findings suggest that some website features have the potential for developing parasocial relationships between online shoppers and online stores, and for heightening consumer affect and fostering store loyalty. 相似文献

This study draws on a sample of participants in online groupsto analyze the interaction between individual-level and communicative-levelfactors that affect public opinion perception. We first assessthe association between individual views on several issues—thedeath penalty, gun regulation and teaching morality in publicschools—and false consensus, i.e., the tendency to attributeown views to others. We also examine whether the associationbetween individual opinion and false consensus is mitigatedby perceived disagreement with offline discussion networks andwith participants in online discussion groups. As expected,not only is there a correlation between personal and perceivedopinion, but also those who strongly favor the three policiesestimate public support to be higher than do those who are unfavorableor moderate. Multivariate models further show that encounteringdisagreement, online or offline, attenuates the associationbetween the individual opinion and false consensus. Theoreticaland practical implications of these findings are discussed. 相似文献

Authority control is discussed from two viewpoints: The need for bibliographic records relating to a name to be brought together under one form of the name; and the need for cross references to direct a user to a heading from variant forms of the name. Data from two research projects that support the need for choosing one form of name are summarized. The author's study of user requests that resulted in no "hits" in an online catalog is described. Data are given to show that for only 6.4% of these requests would our current methods of cross referencing in authority records have been helpful, and that two system programs would have given much greater assistance. 相似文献

ABSTRACT Many academic librarians use online information literacy tutorials as an alternative or a supplement to in-class library instruction. Tutorials created with streaming media software such as Camtasia Studio have become increasingly popular. Librarians at a mid-sized Midwestern university have created several such tutorials demonstrating various library resources. The value of streaming-media tutorials is supported by key learning theories such as cognitive load theory, dual coding theory, and multimedia learning theory. However, studies measuring the impact of online tutorials on student learning of information-literacy skills have shown mixed results. The authors tested the effectiveness of an online information literacy tutorial on a group of undergraduate business students. About 140 students in three undergraduate finance classes rated a Value Line online tutorial. Students were also invited to complete a follow-up survey online with Blackboard. This survey measured student knowledge retention of Value Line and interest in online tutorials. The results showed that while students viewed the tutorial positively, they preferred face-to-face instruction from a librarian. Also, while most students could locate the proper links in Value Line, only 30 percent were able to successfully look up a company. Indicators point to a future for online instruction coexisting with, yet not replacing, traditional classroom library instruction. 相似文献

Engaging the Social News User 总被引：1，自引：0，他引：1

One of the most common formats of audience participation in journalism consists of online reader comments in response to articles, weblogs, or online television and radio broadcasts. While initially the audience only commented on media platforms themselves, Facebook made it possible to outsource commenting to a third-party platform. The options users have, the rules commenters are obliged to follow, and the moderation regime they confront, could influence the quantity and quality of comments. In this study, we explore how news media deal with audience comments on Facebook and their own news site, and how this influences the quality and quantity of comments. We compared comments on news platforms and Facebook of 62 Dutch national and regional newspapers, public and commercial broadcasters, newsweeklies, national news programmes, and online news sites. Subsequently, we analysed the content of the comments with the qualitative text analysis tool MAXQDA. The results indicate that news media prefer outsourcing comments to Facebook although commenting on their own platforms is still possible. By discouraging anonymous responses, the quality of comments improved but above all the quantity of comments decreased after outsourcing comments to Facebook. 相似文献

‘Adults don’t understand’: exploring how teens use dialectical frameworks to navigate webs of tensions in online life 总被引：1，自引：0，他引：1
As communication increasingly takes place online and via mobile technologies, young people are the fastest growing adopters of new online platforms. Consequently, communication scholars have begun to consider young people’s experiences online, comparing online and offline interactions, establishing how developmental stages affect youth’s engagement with online content, and documenting risks for youth’s experience online. We argue that much can be gained from a ‘tension-centered’ approach that highlights the competing demands of young people’s online engagement and problematizes current conceptions of risk. Through focus group interviews with teens, we examine current trends of online activity and re-conceptualize opportunities for conducting research with youth. Teens’ ‘local logics’ for negotiation webs of communicative tensions online reveal articulation of formal rules, which are later eclipsed by lived experiences. We offer strategies for parents, caregivers, and educators to more productively engage with youth about their online experiences, as well as implications for communication researchers. 相似文献
