    Abstract
    Purpose - Following the assumption that studies of information inequality need to be based on precise discrimination between society's information rich and poor and against the context that a mechanism for such discrimination is still lacking, the purpose of this paper is to explore the possibility of establishing a holistic informational measurement. Design/methodology/approach - It does so by developing a measurement based on the conceptualization of the individual as an information agent and his/her information world as his/her characterization. The development procedure consists of four steps: operationalization of the theoretical constructs and the initial drafting of the questionnaire instrument; revisions of the questionnaire based on pilot tests with small groups of people; weighing of the questionnaire items for the purpose of calculating index-type variable scores; formal test of validity and reliability. Findings - The resulting measurement consists of eight variables corresponding to eight theoretical constructs of an individual's information world, each being measured by a group of questionnaire-based items which, in turn, generate an index-type score as the variable's value. Validity and reliability tests show that the measurement is, on the whole, able to distinguish the information poor from the information rich and to measure individuals consistently. Originality/value - The study demonstrates that it is possible to distinguish the information rich and poor by informational measurement in the same way as to distinguish economic groups by income, ethnic groups by race and intelligence groups by IQ; and that such a measurement has arguably multifaceted value for information inequality research.

    Abstract
    Purpose - This study aims to investigate the discourses surrounding the provision of internet access in Singapore through the public library system and to consider what the government, librarians and members of the public consider are the legitimate uses of the internet in Singapore's public libraries, how these compare with what the librarians see as their role in facilitating access and to what extent the internet as an educational tool features in public libraries according to users. Design/methodology/approach - A discourse analysis of public documents and semi-structured interviews with ten senior librarians, managers, and 40 members of the public were conducted. Observation was also conducted of library users and of their usage at the computer terminals in the library. Findings - Findings from the study throw up very different definitions of what constitutes learning through the internet within the context of a public library. This reinforces conclusions from previous studies that what is termed learning through the internet is variously constructed, and understood in multiple ways. This defies what is often presented of the internet as a technical quick fix of policy makers to help its population leap frog into the future. Research limitations/implications - While the study provided a glimpse into the discourse surrounding the internet in one country, similar work should be carried in more Asian countries to provide a more comprehensive survey of the region and compare this with findings conducted in an Occidental setting. Originality/value - The study provides an Asian perspective that complements findings on the various discourses that had surrounded internet technology in the USA and Europe. It also calls for a new spirit of awareness on the part of librarians to the views of library users with regard to internet access.

    Abstract
    The increasing use and prominence of web archives raises the urgency of establishing mechanisms for transparency in the making of web archives to facilitate the process of evaluating a web archive's provenance, scoping, and absences. Some choices and process events are captured automatically, but their interactions are not currently well understood or documented. This study examined the decision space of web archives and its role in shaping what is and what is not captured in the web archiving process. By comparing how three different web archives collections were created and documented, we investigate how curatorial decisions interact with technical and external factors and we compare commonalities and differences. The findings reveal the need to understand both the social and technical context that shapes those decisions and the ways in which these individual decisions interact. Based on the study, we propose a framework for documenting key dimensions of a collection that addresses the situated nature of the organizational context, technical specificities, and unique characteristics of web materials that are the focus of a collection. The framework enables future researchers to undertake empirical work studying the process of creating web archives collections in different contexts.

    Abstract
    Recent work by Evans, Cordova, and Sipole (2014) reveals that in the two months leading up to the 2012 election, female House candidates used the social media site Twitter more often than male candidates. Not only did female candidates tweet more often, but they also spent more time attacking their opponents and discussing important issues in American politics. In this article, we examine whether the female winners of those races acted differently than the male winners in the 2012 election, and whether they differed in their tweeting-style during two months in the summer of 2013. Using a hand-coded content analysis of every tweet from each member in the U.S. House of Representatives in June and July of 2013, we show that women differ from their male colleagues in their frequency and type of tweeting, and note some key differences between the period during the election and the period after. This article suggests that context greatly affects representatives' Twitter-style.

    Abstract
    Micro-blogging services such as Twitter represent constantly evolving, user-generated sources of information. Previous studies show that users search such content regularly but are often dissatisfied with current search facilities. We argue that an enhanced understanding of the motivations for search would aid the design of improved search systems, better reflecting what people need. Building on previous research, we present qualitative analyses of two sources of data regarding how and why people search Twitter. The first, a diary study (p?=?68), provides descriptions of Twitter information needs (n?=?117) and important meta-data from active study participants. The second data set was established by collecting first-person descriptions of search behavior (n?=?388) tweeted by twitter users themselves (p?=?381) and complements the first data set by providing similar descriptions from a more plentiful source. The results of our analyses reveal numerous characteristics of Twitter search that differentiate it from more commonly studied search domains, such as web search. The findings also shed light on some of the difficulties users encounter. By highlighting examples that go beyond those previously published, this article adds to the understanding of how and why people search such content. Based on these new insights, we conclude with a discussion of possible design implications for search systems that index micro-blogging content.

    Abstract
    This article estimates the first constant quality price index for Internet domain names. The suggested index provides a benchmark for domain name traders and investors looking for information on price trends, historical returns, and the fundamental risk of Internet domain names. The index increases transparency in the market for this newly emerged asset class. A cointegration analysis shows that domain registrations and resale prices form a long-run equilibrium and indicates supply constraints in domain space. This study explores a large data set of domain sales spanning the years 2006 to 2013. Differences in the quality of individual domain names are controlled for in hedonic repeat sales regressions.

    Abstract
    Indexing remains one of the most popular tools provided by digital libraries to help users identify and understand the characteristics of the information they need. Despite extensive studies of the problem of automatic index construction for text-based digital libraries, the construction of multimedia digital libraries continues to represent a challenge, because multimedia objects usually lack sufficient text information to ensure reliable index learning. This research attempts to tackle the problem of automatic index construction for multimedia objects by employing Web usage logs and limited keywords pertaining to multimedia objects. The tests of two proposed algorithms use two different data sets with different amounts of textual information. Web usage logs offer precious information for building indexes of multimedia digital libraries with limited textual information. The proposed methods generally yield better indexes, especially for the artwork data set.

    Webcasting systems were developed to provide remote access in real-time to live events. Today, these systems have an additional requirement: to accommodate the "second life" of webcasts as archival information objects. Research to date has focused on facilitating the production and storage of webcasts as well as the development of more interactive and collaborative multimedia tools to support the event, but research has not examined how people interact with a webcasting system to access and use the contents of those archived events. Using an experimental design, this study examined how 16 typical users interact with a webcasting system to respond to a set of information tasks: selecting a webcast, searching for specific information, and making a gist of a webcast. Using several data sources that included user actions, user perceptions, and user explanations of their actions and decisions, the study also examined the strategies employed to complete the tasks. The results revealed distinctive system-use patterns for each task and provided insights into the types of tools needed to make webcasting systems better suited for also using the webcasts as information objects.

    Abstract
    This article presents conceptual navigation and NavCon, an architecture that implements this navigation in World Wide Web pages. NavCon architecture makes use of ontology as metadata to contextualize user search for information. Based on ontologies, NavCon automatically inserts conceptual links in Web pages. By using these links, the user may navigate in a graph representing ontology concepts and their relationships. By browsing this graph, it is possible to reach documents associated with the user desired ontology concept. This Web navigation supported by ontology concepts we call conceptual navigation. Conceptual navigation is a technique to browse Web sites within a context. The context filters relevant retrieved information. The context also drives user navigation through paths that meet his needs. A company may implement conceptual navigation to improve user search for information in a knowledge management environment. We suggest that the use of an ontology to conduct navigation in an Intranet may help the user to have a better understanding about the knowledge structure of the company.

    Abstract
    Purpose - This paper is the final one in a series which has tried to give an overview of so-called transformational areas of digital library technology. The aim has been to assess how much real transformation these applications can bring about, in terms of creating genuine user benefit and also changing everyday library practice. Design/methodology/approach - The paper provides a summary of some of the legal and ethical issues associated with web 2.0 applications in libraries, associated with a brief retrospective view of some relevant literature. Findings - Although web 2.0 innovations have had a massive impact on the larger World Wide Web, the practical impact on library service delivery has been limited to date. What probably can be termed transformational in the effect of web 2.0 developments on library and information work is their effect on some underlying principles of professional practice. Research limitations/implications - The legal and ethical challenges of incorporating web 2.0 platforms into mainstream institutional service delivery need to be subject to further research, so that the risks associated with these innovations are better understood at the strategic and policy-making level. Practical implications - This paper makes some recommendations about new principles of library and information practice which will help practitioners make better sense of these innovations in their overall information environment. Social implications - The paper puts in context some of the more problematic social impacts of web 2.0 innovations, without denying the undeniable positive contribution of social networking to the sphere of human interactivity. Originality/value - This paper raises some cautionary points about web 2.0 applications without adopting a precautionary approach of total prohibition. However, none of the suggestions or analysis in this piece should be considered to constitute legal advice. If such advice is required, the reader should consult appropriate legal professionals.

    Abstract
    Drawing on identity theory and privacy research, this article argues that the need for self-identity is a key factor affecting people's privacy behavior in social networking sites. I first unpack the mainstream, autonomy-centric discourse of privacy, and then present a research model that illustrates a possible new theorization of the relationship between self-identity and information privacy. An empirical study with Facebook users confirms the main hypotheses. In particular, the data show that the need for self-identity is positively related to privacy management behaviors, which in turn result in increased self-disclosure in online social networks. I subsequently argue that the so-called "privacy paradox" is not a paradox per se in the context of online social networking; rather, privacy concerns reflect the ideology of an autonomous self, whereas social construction of self-identity explains voluntary self-disclosure.

    Abstract
    Managing the constant flow of incoming messages is a daily challenge faced by knowledge workers who use technologies such as e-mail and other digital communication tools. This study focuses on the most ubiquitous of these technologies, e-mail, and unobtrusively explores the ongoing inbox-management activities of thousands of users worldwide over a period of 8 months. The study describes the dynamics of these inboxes throughout the day and the week as users strive to handle incoming messages, read them, classify them, respond to them in a timely manner, and archive them for future reference, all while carrying out the daily tasks of knowledge workers. It then tests several hypotheses about the influence of specific inbox-management behaviors in mitigating the causes of e-mail overload, and proposes a continuous index that quantifies one of these inbox-management behaviors. This inbox clearing index (ICI) expands on the widely cited trichotomous classification of users into frequent filers, spring cleaners, and no filers, as suggested by Whittaker and Sidner (1996). We propose that the ICI allows shifting the focus, from classifying users to characterizing a diversity of user behaviors and measuring the relationships between these behaviors and desired outcomes.

    Abstract
    Scholars and practitioners alike increasingly emphasize the importance of the virtual world as a new medium of communication. Key to the success of this digital medium is its ability to support information exchange when compared with face-to-face communication. Its potential is highlighted by the literature illustrating the inadequacy of traditional computer-mediated communication (CMC) tools, such as e-mail and video conferencing, to support communication among geographically dispersed coworkers. Many of the traditional CMC tools lack the needed support for effective information exchange to varying degrees. The emergence of a sophisticated virtual world, such as Second Life, has met this dearth. We draw on the theories of task closure and media richness to propose a parsimonious model of information exchange behavior in a virtual world context. Observations from a series of group-based project discussion sessions in face-to-face and virtual world settings, respectively, suggest that the information exchange between coworkers in both settings could be similar. Specifically, virtual coworkers might be able to achieve task closure (i.e., the complete transmission of intended work-related information) in the same way as their counterparts in the face-to-face context.

    Abstract
    Web accessibility (WA) is an innovation in Web design; it can be considered as part of the corporate social responsibility (CSR) strategy of the firms. As adoption of innovations and CSR commitment are linked with firm size and national culture/legislation, we hypothesize that size and national culture/legislation, may have an effect on WA level. The authors studied an international sample made up of companies included in EUROSTOXX600 (The STOXX Europe 600 Index). The main results suggest that both size and culture have a significant effect on WA. Large firms as well as Anglo-Saxon companies are more prone to have higher WA levels. A deeper analysis, which was done through the estimation of quantile regression equations, showed that the influence of size is significant for companies trying to excel or for those trying to avoid the worst WA. However, the effect of size is significant only in the lowest part of the conditional distribution.

    Abstract
    A substantial amount of research has focused on the persistence or availability of Web citations. The present study analyzes Web citation distributions. Web citations are defined as the mentions of the URLs of Web pages (Web resources) as references in academic papers. The present paper primarily focuses on the analysis of the URLs of Web citations and uses three sets of data, namely, Set 1 from the Humanities and Social Science Index in China (CSSCI, 1998-2009), Set 2 from the publications of two international computer science societies, Communications of the ACM and IEEE Computer (1995-1999), and Set 3 from the medical science database, MEDLINE, of the National Library of Medicine (1994-2006). Web citation distributions are investigated based on Web site types, Web page types, URL frequencies, URL depths, URL lengths, and year of article publication. Results show significant differences in the Web citation distributions among the three data sets. However, when the URLs of Web citations with the same hostnames are aggregated, the distributions in the three data sets are consistent with the power law (the Lotka function).

    Abstract
    Beschrieben wird die Entwicklung eines Systems, das auf Basis einer Point Of Interest-Datenbank eine automatische Freizeitplanung durchführt. Nach Auswahl eines Tagesthemas wie z. B. "Tag in der Natur" oder "Tag zu zweit", entwirft das System einen thematisch passenden Tagesplan mit mehreren Etappen in zeitlicher Abfolge. Zunächst wird das entwickelte System grob vorgestellt, gefolgt von einem Überblick über ähnliche aktuelle Forschungen. Im Anschluss folgen eine kurze Einführung in den Mashup-Begriff sowie eine Beschreibung der vom System genutzten Dienste. Schließlich werden die Komponenten des Systems erklärt und ein Ausblick in die Zukunft der POI-Dienste und -Suchmaschinen gegeben.

    Abstract
    University libraries invest a massive amount of resources in digitizing information for the Web, yet there is growing concern that much of this information is being underutilized. The present study uses the technology acceptance model (TAM) to investigate university library website resources (ULWR) usage. We categorize users based on academic roles and then analyze them as subgroups in order to observe different adoption patterns across groups. A total of 299 usable responses was collected from four different universities and across three populations: undergraduate, master, and doctoral student/faculty groups. The findings show that different library users indeed access ULWR for different reasons, resulting in a need for tailored managerial efforts. Overall, the extended TAM explains undergraduate students' usage best; the explanatory power of the model is significantly lower for the doctoral student/faculty group. Some of the findings challenge results reported in TAM research in other fields. The unexpected findings may result from the application of the model to a different context. Detailed theoretical implications and managerial guidance are offered.
