This article presents an innovative methodology to study computer-mediated communication (CMC), which allows analysis of the multi-layered effects of online expression and reception. The methodology is demonstrated by combining the following three data sets collected from a widely tested eHealth system, the Comprehensive Health Enhancement Support System (CHESS): (1) a flexible and precise computer-aided content analysis; (2) a record of individual message posting and reading; and (3) longitudinal survey data. Further, this article discusses how the resulting data can be applied to online social network analysis and demonstrates how to construct two distinct types of online social networks—open and targeted communication networks—for different types of content embedded in social networks.  相似文献

In recent years, the amount of video content created and uploaded to the Internet has grown exponentially. Video content has unique accessibility challenges: indexing, transcribing, and searching video has always been very labor intensive, and there were no automated ways of searching videos for specific content. New software tools that use deep learning methods are automating some of these processes, making video content more discoverable and useful. There are also many new tools for processing and manipulating video in interesting ways. This column will briefly discuss the idea of deep learning and how deep learning tools can be used to transcribe, translate, search, and even manipulate videos. It will suggest ways that librarians can use these tools to help their institutions better manage video content. It also includes a list of video-related software tools.  相似文献

This study adopts a public value perspective to examine the eHealth services deployed by national and regional governments to contain the coronavirus (Covid-19) pandemic, including symptoms checkers, information portals and contact-tracing applications. We analyse 50 cases of eHealth applications adopted in 25 European Economic Area (EEA) and outline how these systems and technologies map against four dimensions of public value: user orientation, participation, legality and equity. Our findings reveal that the public value of the eHealth applications adopted in the context of the current pandemic is affected by both endogenous and exogenous factors that undermine their ability to improve the quality of healthcare services and social wellbeing. We conclude by suggesting areas for further research to address such factors and the trade-offs emerging between different dimensions of public value.  相似文献

Governments increasingly use algorithmic models to inform their policy making process. Many suggest that employing such quantifications will lead to more efficient, more effective or otherwise better quality policy making. Yet, it remains unclear to what extent these benefits materialize and if so, how they are brought about. This paper draws on the sociology and policy science literature to study how algorithmic models, a particular type of quantification, are used in policy analysis. It presents the outcomes of 38 unstructured interviews with data scientists, policy analysts, and policy makers that work with algorithmic models in government. Based on an in-depth analysis of these interviews, I conclude that the usefulness of algorithmic models in policy analysis is best understood in terms of the commensurability of these quantifications. However, these broad communicative and organizational benefits can only be brought about if algorithmic models are handled with care. Otherwise, they may propagate bias, exclude particular social groups, and will entrench existing worldviews.  相似文献

The number of Web users whose first language is not English continues to grow, as does the amount of content provided in languages other than English. This poses new challenges for actors on the Web, such as in which language(s) content should be offered, how search tools should deal with mono- and multilingual content, and how users can make the best use of navigation and search options, suited to their individual linguistic skills. How should these challenges be dealt with? Technological approaches to non-English (or in general, cross-language) Web search have made large progress; however, translation remains a hard problem. This precludes a low-cost but high-quality blanket all-language coverage of the whole Web. In this paper, we propose a user-centric approach to answering questions of where to best concentrate efforts and investments. Drawing on linguistic research, we describe data on the availability of content and access to it in first and second languages across the Web. We then present three studies that investigated the impact of the availability (or not) of first-language content and access forms on user behaviour and attitudes. The results indicate that non-English languages are under-represented on the Web and that this is partly due to content-creation, link-setting and link-following behaviour. They also show that user satisfaction is influenced both by the cognitive effort of searching and the availability of alternative information in that language. These findings suggest that more cross-language tools are desirable. However, they also indicate that context (such as user groups’ domain expertise or site type) should be considered when tradeoffs between information quality and multilinguality need to be taken into account.  相似文献

It is estimated that by 2050, 70% of the population will be urban (Nations Unies, 2014). This massive urbanization has created unprecedented challenges for cities and city managers which has led many of them to look for technological solutions to address them, including the use of Big Data, which is among the most considered technological support to help improve the overall operational and service delivery of cities. It is estimated that around 7 billion connected objects will soon be implemented in cities worldwide which will produce an unprecedented and massive amount of real-time data that will have to be managed, used, and analyzed effectively.If this massive amount of data is effectively managed and used, it can provide important benefits and produce real positive impacts on the functioning of cities. Nonetheless, despite these benefits, only a few cities are able to use and exploit big data, and some studies have shown that less than 0.5% of all the available data has been explored. The objective of this study is to understand the factors that influence cities to use big data and the nature of such use. Based on a field survey involving 106 municipalities, this study investigates the antecedents of big data use by cities and shows how different sets of antecedents influence three different types of big data use by cities.  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

Since its inception in 2013, one of the key contributions of the CLEF eHealth evaluation campaign has been the organization of an ad-hoc information retrieval (IR) benchmarking task. This IR task evaluates systems intended to support laypeople searching for and understanding health information. Each year the task provides registered participants with standard IR test collections consisting of a document collection and topic set. Participants then return retrieval results obtained by their IR systems for each query, which are assessed using a pooling procedure. In this article we focus on CLEF eHealth 2013 and 2014s retrieval task, which saw topics created based on patients’ information needs associated with their medical discharge summaries. We overview the task and datasets created, and the results obtained by participating teams over these two years. We then provide a detailed comparative analysis of the results, and conduct an evaluation of the datasets in the light of these results. This twofold study of the evaluation campaign teaches us about technical aspects of medical IR, such as the effectiveness of query expansion; the quality and characteristics of CLEF eHealth IR datasets, such as their reliability; and how to run an IR evaluation campaign in the medical domain.  相似文献

ABSTRACT

The human papillomavirus (HPV) is one of the most common but preventable sexually transmitted infections that affect males and females but knowledge about it and vaccine uptake remain low. As organizations adopt eHealth communication strategies to communicate about HPV, this study examines the association between eHealth literacy (and related elements) and the motivators for HPV prevention that are based on the protection motivation theory. A survey was conducted among 472 young adults in Kenya and results show moderate eHealth literacy (M = 3.21, SD = 1.03) and online information seeking (M = 3.57, SD = 1.08) but low HPV knowledge and risk perception. eHealth literacy was correlated with HPV knowledge, perceived risk, self-efficacy, and response efficacy whereas online health information seeking were correlated with perceived seriousness of HPV infection. This study suggests examining the discrepancy between online information seeking and knowledge and the disparities in eHealth literacy among young adults in HPV communication.  相似文献

Despite the ever-growing range of media types, formats, and information-access options, students are often instructed to only use specific sources in their research. They are sometimes even given strict guidelines, prescribing how many of each they need to, or may, cite. It is important not to lead students to believe there is a formula for the ideal works cited for all research topics. In contrast, students should learn to think critically about the content and appropriateness of each potential source rather than choosing it only because it is a book, a journal article, a Website, etc. This article argues that requiring students to use, or not use, a source based solely on its format or media type encourages students to choose sources for wrong reasons, pushing critical thinking and source-content evaluation to the periphery of their research processes.  相似文献

OBJECTIVES: Despite the growing use of online databases by clinicians, there has been very little research documenting how effectively they are used. This study assessed the ability of medical and nurse-practitioner students to answer clinical questions using an information retrieval system. It also attempted to identify the demographic, experience, cognitive, personality, search mechanics, and user-satisfaction factors associated with successful use of a retrieval system. METHODS: Twenty-nine students completed questionnaires of clinical and computer experience as well as tests of cognitive abilities and personality type. They were then administered three clinical questions to answer in a medical library setting using the MEDLINE database and electronic and print full-text resources. RESULTS: Medical students were able to answer more questions correctly than nurse-practitioner students before and after searching, but both had comparable improvements in the number of correct questions before and after searching. Successful ability to answer questions was also associated with having experience in literature searching and higher standardized test-score percentiles. CONCLUSIONS: Medical and nurse-practitioner students obtained comparable benefits in the ability to answer clinical questions from use of the information retrieval system. Future research must examine strategies that improve successful search and retrieval of clinical questions posed by clinicians in practice.  相似文献

German universities built over the years highly specialized book collections for use by faculty and graduate students. The German term, seminarbibliothek, is often applied to these types of collections, although examples can be found in universities across Europe. The purpose of this article is to examine a similar type of collection using ebooks in veterinary science and to compare this collection to the standard subject classified ebook collections. Most collection development in college and university libraries focuses on academic subjects. The type of collection being described here focuses on a mission. A mission-focused collection increases the use of library holdings and greatly benefits the stakeholders within the institution. This study looks at how such a collection might be formed and defined and what possible effects this might have on the use of collections of this type.  相似文献

Two law librarians from Duke University have been teaching a course on legal research for non-lawyers since 1986 as part of the Duke Continuing Education program. The course is designed to help the general public understand how the legal system works and how to use legal materials to find the law. This article explores the purpose and organization of the course, and the benefits derived from teaching it.  相似文献

This paper describes the application of zero-base budgeting to libraries and the procedures involved in setting up this type of budget. It describes the "decision packages" necessary when this systmem is employed, as well as how to rank the packages and the problems which are related to the process. Zero-base budgeting involves the entire staff of a library, and the incentive engendered makes for a better and more realistic budget. The paper concludes with the problems which one might encounter in zero-base budgeting and the major benefits of the system.  相似文献

Police departments increasingly use social media for enhancing their relationships with citizens. However, little is known about how specific characteristics of police-initiated messages affect whether and to what extent citizens engage with the former. This study looks at 11 large police departments using Twitter in Germany. Based on a multimethod approach, it explores the effect of content type and two emotional elements (i.e. arousal and valence) of tweets on different dimensions of citizen engagement. The latter is measured as observable online behavioral responses to police tweets in form of likes, comments, and retweets. The results suggest that emotional arousal (i.e. the emotional intensity of a tweet) plays a key role in triggering all forms of citizen engagement, while emotional valence (more specifically, the negativity of a tweet) largely shows no effect. Moreover, the impact of content type (informative versus interactive) varies across the different engagement dimensions.  相似文献
