Pictures tell a story: antecedents of rich-media curation in social network sites

This study explores a new aspect of online social networking, in which textual information has been largely replaced by the curation of rich-media content. We examine these ‘curation-based’ networks (CBN) and develop a theoretical model of the antecedents of intentions to curate rich-media content. Results from the empirical analysis of 449 users of Pinterest, a popular CBN, show that users undertake curation tasks to achieve objectives around the management, discovery, and presentation of rich-media content. The findings have implications for researchers and practitioners interested in the changing nature of online social networks and the role of rich-media in online communication.     

LIBRARIES,SOCIAL SOFTWARE AND DISTANCE LEARNERS: BLOG IT,TAG IT,SHARE IT!

This paper describes a recent project funded by the University of London to explore how social software or Web 2.0 technologies can enhance the use of libraries by distance learners. LASSIE (Libraries And Social Software In Education) involves a team of librarians, learning technologists and archivists. The project first conducted an extensive literature review, which is available online. The literature review provides an overview of key social software and explores the current implementation of these tools by libraries. It also considers the key issues in supporting distance learners’ use of libraries and whether social software might provide solutions. The literature review was followed by several case studies to explore specific types of social software in practice. These included the use of social bookmarking for sharing resources, social software and online reading lists, blogging in the library community, the use of social networking sites and podcasting for information literacy support. LASSIE will be completed in December 2007 and a final report with results from the case studies and an updated literature review will be made available from the project website. One of the successes of the project has been to establish a project blog, which provides the project team with an opportunity to reflect on progress, but also to gather opinions from others in the field.     

Striking a Balance: Effective Use of Facebook in an Academic Library

As one of the fastest growing social networking sites, Facebook presents librarians with a prime opportunity to engage academic library patrons. A survey of 136 users at Western Michigan University (WMU) measured the effectiveness of Facebook as a marketing, reference, and instruction tool. It also measured user comfort and satisfaction with a library's presence on Facebook. The majority of respondents found Facebook to be a useful and engaging medium to learn about library resources and services. The results of this study indicate that an effective library Facebook page must maintain a balance between providing pertinent and useful information and preserving patron privacy. In a second study also included in this article, data from a survey of 14 peer institutions of Western Michigan University positions WMU's local survey within the context of their peer's use of Facebook. The survey of peer institutions concludes that most libraries use Facebook for marketing and outreach purposes.     

A Mightier Pin: Creating a Credible Reference Library on Pinterest at Murray State University

This case study shows how the reference librarians at Murray State University use Pinterest as an added component in reference services. Statistics were collected in an attempt to monitor the number of items shared with the number of people who actively follow each board. This study will help interested reference librarians gain an understanding of how this social media site can be used to promote online resources, both those owned by the institution and those available freely on the internet. It will also serve as an example of how reference librarians can build a reference library within the confines of social media.     

Personalisation and recommender systems in digital libraries

Widespread use of the Internet has resulted in digital libraries that are increasingly used by diverse communities of users for diverse purposes and in which sharing and collaboration have become important social elements. As such libraries become commonplace, as their contents and services become more varied, and as their patrons become more experienced with computer technology, users will expect more sophisticated services from these libraries. A simple search function, normally an integral part of any digital library, increasingly leads to user frustration as user needs become more complex and as the volume of managed information increases. Proactive digital libraries, where the library evolves from being passive and untailored, are seen as offering great potential for addressing and overcoming these issues and include techniques such as personalisation and recommender systems. In this paper, following on from the DELOS/NSF Working Group on Personalisation and Recommender Systems for Digital Libraries, which met and reported during 2003, we present some background material on the scope of personalisation and recommender systems in digital libraries. We then outline the working group’s vision for the evolution of digital libraries and the role that personalisation and recommender systems will play, and we present a series of research challenges and specific recommendations and research priorities for the field.     

Formation and Effect of Social Media Usage Habit

The widespread of social media (SM) provides information system (IS) research with a great opportunity to examine IS usage habit. This study adapts habit perspectives of social psychology into social media use and contextualizes findings from both service marketing and IS usage literature for developing a model of SM usage habit. The model suggests a set of behavior-, goal-, affect-, and expectation-based factors that drive the formation of habit for SM use, which in turn influences future usage behavior. By testing the model with a longitudinal field survey of 518 social networking service (SNS) users, this study provides an integrative context-specific view of SM usage habit and addresses unconscious habitual IS use beyond the traditional perspectives of conscious intentional behavior. The findings have important implications for promoting sustainability of social media applications and services.

Online social networking and psychological experiences: The perceptions of young people with mental health difficulties

ObjectivesThis study explores the interaction between online social networking experiences and wellbeing in 12 young people accessing mental health services.MethodsData from semi-structured interviews was analysed using Grounded Theory methodology.Results“Threats and judgement” and “connection and support” were experienced by adolescents, facilitated by having continuous access to a vast social network. These experiences influenced adolescents' psychological wellbeing, mediated by their responses to threat and judgement and maintaining “safe sharing” with their network. Social network use was conceived as a gamble of balancing its potentially positive and negative impact in a culture in which social network use appears to be unavoidable.ConclusionsThe findings indicate the importance of routine assessment and formulation of social networking use in understanding adolescents' psychological distress. Furthermore, a range of opportunities exist for clinicians to utilise the anonymity and peer support that social networks offer to broaden the range of mental health services offered to young people.

Cross-community context management in Cooperating Smart Spaces

Recently, social networks have become the most prevalent IT paradigm, as the vast majority of Internet users maintain one or multiple social networking accounts. These accounts, irrespectively of the underlying service, contain rich information and data for the owner’s preferences, social skills, everyday activities, beliefs and interests. Along with these services, the computation, sensing and networking capabilities of the state of the art mobile and portable devices, with their always-on mode, assist users in their everyday lives. Thus, the integration of social networking services with current pervasive computing systems could provide the users with the potential to interact with other users that have similar interests, preferences and expectations; and in general, the same or similar context, for limited or not time periods, in order to ameliorate their overall experience, communicate, socialise and improve their everyday activities with minimal effort. This paper introduces a cross-community context management framework that is suitable for Cooperating Smart Spaces, which couple the advantages of pervasive computing and social networking. This framework goes beyond the state of the art, among others, in that cross-community context from a multitude of sources is collected and processed to enhance the end user experience and increase the perceived value of the services provided.     

Reframing Pinterest: Information Literacy for Interior Design Students

This article discusses providing information literacy to interior design students, specifically how over a few years, and several assignment iterations, we moved from a more traditional one-shot library instruction session to a creative Association of College and Research Libraries Framework-inspired assignment using Pinterest as the medium for the students' professionally relevant research project. The outcome of our instruction relied on flexible assignment planning, collaboration as faculty and librarians changed roles, and a focus on information literacy skills needed by professional designers.     

COLLABORATIVE FILTERING: A NEW APPROACH TO SEARCHING DIGITAL LIBRARIES

At Oregon State University (OSU), the School of Electrical Engineering and Computer Science (EECS) and the OSU Libraries are working together on a project to improve the effectiveness and accessibility of digital information created and collected by academic libraries. This project focuses on making digital resources more accessible through an innovative search interface that incorporates collaborative filtering. New approaches to search interfaces will help make the growing wealth of online content more accessible and useful. This paper discusses the problem, explains how collaborative filtering works, describes the System for Electronic Recommendation Filtering (SERF), and then presents initial results from an installation in the OSU Libraries. The productive collaboration at OSU between the Libraries and EECS portends the future of development of search systems; by working together, we can harness the expertise of librarians, computer scientists, and information users to develop more useful search interfaces and increase access to the libraries’ resources and services.     

Relationship Identification Across Heterogeneous Online Social Networks

In the era of the social web, many people manage their social relationships through various online social networking services. It has been found that identifying the types of social relationships among users in online social networks facilitates the marketing of products via electronic “word of mouth.” However, it is a great challenge to identify the types of social relationships, given very limited information in a social network. In this article, we study how to identify the types of relationships across multiple heterogeneous social networks and examine if combining certain information from different social networks can help improve the identification accuracy. The main contribution of our research is that we develop a novel decision tree initiated random walk model, which takes into account both global network structure and local user behavior to bootstrap the performance of relationship identification. Experiments conducted based on two real‐world social networks, Sina Weibo and Jiepang, demonstrate that the proposed model achieves an average accuracy of 92.0%, significantly outperforming other baseline methods. Our experiments also confirm the effectiveness of combining information from multiple social networks. Moreover, our results reveal that human mobility features indicating location categories, coincidence, and check‐in patterns are among the most discriminative features for relationship identification.     

How compulsive use of social media affects performance: insights from the UK by purpose of use

Positive outcomes of social networking use in both informal and non-educational settings have attracted significant research attention. These benefits include social capital formation, higher job performance and satisfaction, an increased sense of belonging, improved knowledge management skills, and enabling of life-long learning opportunities. Compulsive use of social networking, however, remains a major issue among the younger users, potentially leaving a long-lasting impact on the younger population. Concerns have been raised regarding links between the compulsive use of social media and individual academic, social and physical performance. This study explores the motivations for social networking use, their relations to compulsive use, and implications for academic, physical and social performance, in an effort to inform strategies for the appropriate adoption and utilisation of social networking technologies. The study employs a finite mixture approach to segmenting the sample, and results show that two distinct groups motivated by utilitarian and social objectives respectively drive compulsive use by British students. Unlike previous studies, the UK sample does not display differences in terms of age or gender. This finding highlights the trend of gender agnostic views of social platforms by developers. The paper concludes with a discussion of the implications for practice and future research.     

Disclosing too much? Situational factors affecting information disclosure in social commerce environment

The buying and selling of goods and services are no longer limited to a general website or a physical store as social networks, such as Facebook or Pinterest, are heavily focusing on social commerce. Prior studies have analyzed impact of trust and culture on social commerce, design and interface aspects of it, and intention to use social commerce by general people. Our study is informed by the literature on information disclosure intention, and Communication Privacy Management theory and is motivated by the fundamental premise that intention to self-disclose in social commerce is affected by perceived ownership of information, privacy apathy, the risks and benefits of disclosure and fairness of information exchange. We analyzed data collected from 252 samples using the scenario method. The results show that shoppers’ information disclosure intention is driven by the fairness of information exchange, privacy benefits and privacy apathy.

Risky Social Networking Practices Among “Underage” Users: Lessons for Evidence‐Based Policy

European self‐regulation to ensure children's safety on social networking sites requires that providers ensure children are old enough to use the sites, aware of safety messages, empowered by privacy settings, discouraged from disclosing personal information, and supported by easy to use reporting mechanisms. This article assesses the regulatory framework with findings from a survey of over 25000 9‐ to 16‐year‐olds from 25 European countries. These reveal many underage children users, and many who lack the digital skills to use social networking sites safely. Despite concerns that children defy parental mediation, many comply with parental rules regarding social networking. The implications of the findings are related to policy decisions on lower age limits and self‐regulation of social networking sites.     

Choices in the Paradigm Shift

Abstract

External factors are forcing libraries to seriously evaluate and redefine their purpose within higher education. Libraries have identified themselves as gateways to information. Google, and other Internet search tools, have changed the need and importance of the gatekeeper role in libraries. The authors argue that libraries have a role that is broader than that of gatekeeper. It is necessary to move beyond our existing mental models and truly redefine our unique role based on the needs within the external environment. To develop this broader role, libraries must develop collaborative relationships and leverage existing tools and services.     

Persuasive social features that promote knowledge sharing among tertiary students on social networking sites: An empirical study

Persuasive system features have been widely adopted to encourage attitude and behaviour change. Recently, most social networking sites (SNS) adopt some form of persuasive system features that leverage social influence to deliberately induce prescribed behaviours in their users. However, studies on how these features can be used to promote knowledge sharing are inadequate; particularly, regarding how SNS that have been developed solely for academic purposes can adopt these features to promote knowledge sharing. To address this knowledge gap, this study integrates constructs from the social capital theory and persuasive systems design model to investigate the impact of persuasive social features on knowledge sharing among students of tertiary institutions on academic social networking sites. Data are quantitatively gathered from 218 respondents from tertiary institutions and statistically analyzed. The results suggest that perceived dialogue support and perceived social support have strong influences on knowledge sharing behaviour.
