Abstract

The success or failure of social media is highly dependent on the active participation of its users. In order to examine the influential factors that inspire dynamic and eager participation, this study investigates what motivates social media users to share their personal experiences, information, and social support with anonymous others. A variety of information-sharing activities in social media, including creating postings, photos, and videos in 5 different types of social media: Facebook, Twitter, Delicious, YouTube, and Flickr, were observed. Ten factors: enjoyment, self-efficacy, learning, personal gain, altruism, empathy, social engagement, community interest, reciprocity, and reputation, were tested to identify the motivations of social media users based on reviews of major motivation theories and models. Findings from this study indicate that all of the 10 motivations are influential in encouraging users' information sharing to some degree and strongly correlate with one another. At the same time, motivations differ across the 5 types of social media, given that they deliver different information content and serve different purposes. Understanding such differences in motivations could benefit social media developers and those organizations or institutes that would like to use social media to facilitate communication among their community members; appropriate types of social media could be chosen that would fit their own purposes and they could develop strategies that would encourage their members to contribute to their communities through social media.

Abstract

Purpose - The purpose of this paper is to examine the question of whether modern digital information technologies damage their users' cognitive capacities in some way, and to speculate on how librarians should adapt their services as a consequence of the controversy surrounding this question. Design/methodology/approach - The paper reviews some recent literature on this subject, combined with an examination of the role played by technology, librarians and government in determining the nature of our society's response to problematic aspects of the use of digital, internet-based applications in education. Findings - The paper finds that highly differentiated and highly polemical attitudes to this subject mean that librarians have to acknowledge the existence of important challenges to the apparent consensus about the way information technologies should be used in education in Western societies. This has important consequences for the approach to collection building (the balance between digital versus print provision), for library building design, and for the value which should be placed on systematic information literacy teaching. The existence of such an important debate should also embolden information professionals to make their own insights into these issues more widely known. Research limitations/implications - Some of the findings in this paper are amenable to further development through practitioner-oriented research; however, the bulk of the content used for this paper is derived from the literature on this topic, so there is no original research data presented to back up the assertions made by the author. It is simply an account of a debate which has to be acknowledged by librarians. Practical implications - The implications of the issues under discussion in the paper are presented in clear practical terms, and the consequences for library management made explicit. Social implications - The clash between two different theories of learning and information provision is debated and the links with issues of government policy are explored. The social connections between education and wealth generation are brought into this debate. Originality/value - The paper provides a useful, up-to-date briefing on recent controversial issues in education, information management and socio-economic policy making.

Abstract

In Zeiten zunehmend wissensintensiver Berufsbilder besteht eine große Herausforderung heutiger Unternehmen darin, die zur Unterstützung organisatorischen Handelns erforderliche Information effizient und effektiv zur Verfügung zu stellen. Eine Grundlage für die Entwicklung einer adäquaten Informationsumgebung legt dabei das umfassende Verständnis des Kontexts und Verhaltens von Mitarbeitern im Umgang mit Information. Beides unterliegt jedoch einem steten Wandel und stellt hohe Anforderungen an die Flexibilität von Arbeitsplatzkonzepten und der Gestaltung von Informationsumgebungen. In diesem Artikel wird daher die aktuelle Bedeutung und Entwicklung informationswissenschaftlicher Ansätze zur Modellierung von Informationssuchverhalten, deren Methoden, sowie zentrale Konzepte und Erkenntnisse vorgestellt. Anschließend wird die Bedeutung dieser Modelle für den Arbeitsplatz-Kontext in Zeiten zunehmend wissensintensiver Tätigkeiten untersucht. Anhand der Wandlung des primär informativ genutzten Internet zu einem partizipativen Social Web wird daraufhin erörtert, welche neuen Entwicklungen es in der Erforschung des Nutzerkontexts zu berücksichtigen gilt. Die beispielhafte Betrachtung aktueller Forschungsergebnisse auf diesem Gebiet mündet in einer Diskussion weiteren Forschungsbedarfs.

Abstract

The quality of online health information for consumers has been a critical issue that concerns all stakeholders in healthcare. To gain an understanding of how quality is evaluated, this systematic review examined 165 articles in which researchers evaluated the quality of consumer-oriented health information on the web against predefined criteria. It was found that studies typically evaluated quality in relation to the substance and formality of content, as well as to the design of technological platforms. Attention to design, particularly interactivity, privacy, and social and cultural appropriateness is on the rise, which suggests the permeation of a user-centered perspective into the evaluation of health information systems, and a growing recognition of the need to study these systems from a social-technical perspective. Researchers used many preexisting instruments to facilitate evaluation of the formality of content; however, only a few were used in multiple studies, and their validity was questioned. The quality of content (i.e., accuracy and completeness) was always evaluated using proprietary instruments constructed based on medical guidelines or textbooks. The evaluation results revealed that the quality of health information varied across medical domains and across websites, and that the overall quality remained problematic. Future research is needed to examine the quality of user-generated content and to explore opportunities offered by emerging new media that can facilitate the consumer evaluation of health information.

Abstract

Many discussions exist regarding the credibility of information on the Internet. Similar discussions happen on the interpretation of social scientific research data, for which information triangulation has been proposed as a useful method. In this article, we explore a design theory-consisting of a kernel theory, meta-requirements, and meta-designs-for software and services that triangulate Internet information. The kernel theory identifies 5 triangulation methods based on Churchman's inquiring systems theory and related meta-requirements. These meta-requirements are used to search for existing software and services that contain design features for Internet information triangulation tools. We discuss a prototyping study of the use of an information triangulator among 72 college students and how their use contributes to their opinion formation. From these findings, we conclude that triangulation tools can contribute to opinion formation by information consumers, especially when the tool is not a mere fact checker but includes the search and delivery of alternative views. Finally, we discuss other empirical propositions and design propositions for an agenda for triangulator developers and researchers. In particular, we propose investment in theory triangulation, that is, tools to automatically detect ethically and theoretically alternative information and views.

Abstract

The user-centered approach to information retrieval emphasizes the importance of a user model in determining what information will be most useful to a particular user, given their context. Mediated search provides an opportunity to elaborate on this idea, as an intermediary's elicitations reveal what aspects of the user model they think are worth inquiring about. However, empirical evidence is divided over whether intermediaries actually work to develop a broadly conceived user model. Our research revisits the issue in a web research services setting, whose characteristics are expected to result in more thorough user modeling on the part of intermediaries. Our empirical study confirms that intermediaries engage in rich user modeling. While intermediaries behave differently across settings, our interpretation is that the underlying user model characteristics that intermediaries inquire about in our setting are applicable to other settings as well.
