Abstract

The issue of how teens choose social networks and information communication technologies (ICT's) for personal communication is complex. This study focused on describing how U.S. teens from a highly technological suburban high school select ICT's for personal communication purposes. Two research questions guided the study: (a) What factors influence high school seniors' selection of online social networks and other ICT's for everyday communication? (b) How can social network theory (SNT) help to explain how teens select online social networks and other ICT's for everyday communication purposes? Using focus groups, a purposive sample of 45 teens were asked to discuss (a) their preferred methods for communicating with friends and family and why, (b) the reasons why they chose to engage (or not to engage) in online social networking, (c) how they selected ICT's for social networking and other communication purposes, and (d) how they decided whom to accept as online "friends." Findings indicated that many factors influenced participants' ICT selection practices including six major categories of selection factors: relationship factors, information/communication factors, social factors, systems factors, self-protection factors, and recipient factors. SNT was also helpful in explaining how "friendship" was a major determining factor in their communication media and platform choices.

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

Twitter is a popular microblogging service that is used to read and write millions of short messages on any topic within a 140-character limit. Popular or influential users tweet their status and are retweeted, mentioned, or replied to by their audience. Sentiment analysis of the tweets by popular users and their audience reveals whether the audience is favorable to popular users. We analyzed over 3,000,000 tweets mentioning or replying to the 13 most influential users to determine audience sentiment. Twitter messages reflect the landscape of sentiment toward its most popular users. We used the sentiment analysis technique as a valid popularity indicator or measure. First, we distinguished between the positive and negative audiences of popular users. Second, we found that the sentiments expressed in the tweets by popular users influenced the sentiment of their audience. Third, from the above two findings we developed a positive-negative measure for this influence. Finally, using a Granger causality analysis, we found that the time-series-based positive-negative sentiment change of the audience was related to the real-world sentiment landscape of popular users. We believe that the positive-negative influence measure between popular users and their audience provides new insights into the influence of a user and is related to the real world.

Abstract

We discuss the needs of a knowledge organization scheme for supporting Web-based software applications. We show how it differs from traditional knowledge organization schemes due to the virtual, dynamic, ad-hoc, userspecific and application-specific nature of Web-based knowledge. The sheer size of Web resources also adds to the complexity of organizing knowledge on the Web. As such, a standard, global scheme such as a single ontology for classifying and organizing all Web-based content is unrealistic. There is nevertheless a strong and immediate need for effective knowledge organization schemes to improve the efficiency and effectiveness of Web-based applications. In this context, we propose a novel knowledge organization scheme wherein concepts in the ontology of a domain are semantically interlinked with specific pieces of Web-based content using a rich hyper-linking structure known as Superlinks with well-defined semantic roles. We illustrate how such a knowledge organization scheme improves the efficiency and effectiveness of a Web-based e-commerce retail store.

Abstract

Academic social network sites Academia.edu and ResearchGate, and reference sharing sites Mendeley, Bibsonomy, Zotero, and CiteULike, give scholars the ability to publicize their research outputs and connect with each other. With millions of users, these are a significant addition to the scholarly communication and academic information-seeking eco-structure. There is thus a need to understand the role that they play and the changes, if any, that they can make to the dynamics of academic careers. This article investigates attributes of philosophy scholars on Academia.edu, introducing a median-based, time-normalizing method to adjust for time delays in joining the site. In comparison to students, faculty tend to attract more profile views but female philosophers did not attract more profile views than did males, suggesting that academic capital drives philosophy uses of the site more than does friendship and networking. Secondary analyses of law, history, and computer science confirmed the faculty advantage (in terms of higher profile views) except for females in law and females in computer science. There was also a female advantage for both faculty and students in law and computer science as well as for history students. Hence, Academia.edu overall seems to reflect a hybrid of scholarly norms (the faculty advantage) and a female advantage that is suggestive of general social networking norms. Finally, traditional bibliometric measures did not correlate with any Academia.edu metrics for philosophers, perhaps because more senior academics use the site less extensively or because of the range informal scholarly activities that cannot be measured by bibliometric methods.

Abstract

Although the Internet has become a major source for accessing news, there is little research regarding users' experience with news sites. We conducted an experiment to test a comprehensive model of user experience with news sites that was developed previously by means of an online survey. Level of adoption (novel or adopted site) was controlled with a between-subjects manipulation. We collected participants' answers to psychometric scales at 2 times: after presentation of 5 screenshots of a news site and directly after 10 minutes of hands-on experience with the site. The model was extended with the prediction of users' satisfaction with news sites as a high-level design goal. A psychometric measure of trust in news providers was developed and added to the model to better predict people's intention to use particular news sites. The model presented in this article represents a theoretically founded, empirically tested basis for evaluating news websites, and it holds theoretical relevance to user-experience research in general. Finally, the findings and the model are applied to provide practical guidance in design prioritization.

Abstract

Spam has become an issue of concern in almost all areas where the Internet is involved, and many people today have become victims of spam from publishers and individual journals. We studied this phenomenon in the field of scholarly publishing from the perspective of a single author. We examined 1,024 such spam e-mails received by Marcin Kozak from publishers and journals over a period of 391 days, asking him to submit an article to their journal. We collected the following information: where the request came from; publishing model applied; fees charged; inclusion or not in the Directory of Open Access Journals (DOAJ); and presence or not in Beall's (2014) listing of dubious journals. Our research showed that most of the publishers that sent e-mails inviting manuscripts were (i) using the open access model, (ii) using article-processing charges to fund their journal's operations; (iii) offering very short peer-review times, (iv) on Beall's list, and (v) misrepresenting the location of their headquarters. Some years ago, a letter of invitation to submit an article to a particular journal was considered a kind of distinction. Today, e-mails inviting submissions are generally spam, something that misleads young researchers and irritates experienced ones.

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

The connections and contexts surrounding information shared in social settings must be accounted for, and this is particularly true for online communities that are information-centric. This article presents a mixed-methods study of LibraryThing and Goodreads, which have characteristics of information-centric online communities and social digital libraries, with attention to their roles as boundary objects, users' information values, and information behavior, and other boundaries and boundary objects at play. Content analysis of messages, a survey of users, and qualitative interviews show LibraryThing and Goodreads help establish community and organizational structure; support sharing of information values; and facilitate the building and maintenance of social ties. Translation of meanings and understandings within and between communities is a key activity in these roles. Online communities and social digital libraries should highlight translation processes and resources; provide user profiles and off-topic spaces and encourage their use; take a sociotechnical approach to tailor technology and community features to the right audiences; and facilitate the establishment of shared structure, values, and ties and the work of boundary spanners. Further implications exist for research on and theorizing of information-centric online communities, boundaries, and boundary objects as part of the sociotechnical infrastructure surrounding online information sharing.

Der neue Herausgeber des Brockhaus, ein Tochterverlag von Bertelsmann, hat unterdessen angekündigt, zum gedruckten Lexikon zurückzukehren. Etwa Anfang 2015 soll die 22. Auflage erscheinen. In Zeiten des virtuellen Informationsoverkills gebe es einen Bedarf an Orientierung, an Relevanzvorgaben, sagt Geschäftsführer Christoph Hünermann. Ausgerechnet Bertelsmann druckte 2008 ein knapp 1 000 Seiten langes Wikipedia-Lexikon mit den 50 000 meist gesuchten Begriffen. Eine Experten-Redaktion überprüfte die Einträge sicherheitshalber zuvor - soll allerdings kaum Fehler gefunden haben."

Rez. in Mitt. VÖB 63(2010) H.1/2, S.148-149 (M. Buzinkay): "Endlich wieder ein Buchtitel, der mich nicht nur gleich angesprochen, sondern auch das gehalten, was er versprochen hat. Eine vertiefende Lektüre in ein sehr aktuelles und sehr wichtiges Thema, dass sowohl Einzelpersonen wie auch Organisationen, Unternehmen und Vereine gleichermaßen beschäftigen muss: "Wie Social Media Wirtschaft und Gesellschaft verändern" heißt der Untertitel des Werkes von Erik Qualman. Der Autor liefert für seine Behauptungen ausgesuchte Beispiele, diese seine Argumentation untermauern. Schön ist, dass man diese Beispiele gleich als Hands-on Tipps für seine eigene Online Arbeit nutzen kann. Bei der schier unendlichen Anzahl von Beispielen muss man sich aber fragen, ob man je in der Lage sein wird, diese nützlichen Hinweise jemals nur annähernd im eigenen Unternehmen umzusetzen. Um es kurz zu fassen: man kann das Buch mit ins Bett nehmen und in einem durchlesen. Fad wird einem nicht, nur genug Post-its sollte man mitnehmen, um alles wichtige zu markieren und zu notieren. Am nächsten Morgen sollte man das Buch aber sein lassen, denn das Geheimnis von Socialnomics ist die Umsetzung im Web. Eine dringende Empfehlung an alle Marketing-Interessierten!"

Abstract

"The revolution will be Twittered!" declared journalist Andrew Sullivan after protests erupted in Iran. But as journalist and social commentator Evgeny Morozov argues in "The Net Delusion," the Internet is a tool that both revolutionaries and authoritarian governments can use. For all of the talk in the West about the power of the Internet to democratize societies, regimes in Iran and China are as stable and repressive as ever. Social media sites have been used there to entrench dictators and threaten dissidents, making it harder--not easier--to promote democracy. In this spirited book, journalist and social commentator Evgeny Morozov shows that by falling for the supposedly democratizing nature of the Internet, Western do-gooders may have missed how it also entrenches dictators, threatens dissidents, and makes it harder-not easier-to promote democracy. Buzzwords like "21st-century statecraft" sound good in PowerPoint presentations, but the reality is that "digital diplomacy" requires just as much oversight and consideration as any other kind of diplomacy. Marshalling a compelling set of case studies, " The Net Delusion" shows why the cyber-utopian stance that the Internet is inherently liberating is wrong, and how ambitious and seemingly noble initiatives like the promotion of "Internet freedom" are misguided and, on occasion, harmful.

Abstract

In Digital Methods, Richard Rogers proposes a methodological outlook for social and cultural scholarly research on the Web that seeks to move Internet research beyond the study of online culture. It is not a toolkit for Internet research, or operating instructions for a software package; it deals with broader questions. How can we study social media to learn something about society rather than about social media use? How can hyperlinks reveal not just the value of a Web site but the politics of association? Rogers proposes repurposing Web-native techniques for research into cultural change and societal conditions. We can learn to reapply such "methods of the medium" as crawling and crowd sourcing, PageRank and similar algorithms, tag clouds and other visualizations; we can learn how they handle hits, likes, tags, date stamps, and other Web-native objects. By "thinking along" with devices and the objects they handle, digital research methods can follow the evolving methods of the medium. Rogers uses this new methodological outlook to examine the findings of inquiries into 9/11 search results, the recognition of climate change skeptics by climate-change-related Web sites, the events surrounding the Srebrenica massacre according to Dutch, Serbian, Bosnian, and Croatian Wikipedias, presidential candidates' social media "friends," and the censorship of the Iranian Web. With Digital Methods, Rogers introduces a new vision and method for Internet research and at the same time applies them to the Web's objects of study, from tiny particles (hyperlinks) to large masses (social media).

Abstract

How sharing the mundane details of daily life did not start with Facebook, Twitter, and YouTube but with pocket diaries, photo albums, and baby books. Social critiques argue that social media have made us narcissistic, that Facebook, Twitter, Instagram, and YouTube are all vehicles for me-promotion. In The Qualified Self, Lee Humphreys offers a different view. She shows that sharing the mundane details of our lives?what we ate for lunch, where we went on vacation, who dropped in for a visit?didn't begin with mobile devices and social media. People have used media to catalog and share their lives for several centuries. Pocket diaries, photo albums, and baby books are the predigital precursors of today's digital and mobile platforms for posting text and images. The ability to take selfies has not turned us into needy narcissists; it's part of a longer story about how people account for everyday life. Humphreys refers to diaries in which eighteenth-century daily life is documented with the brevity and precision of a tweet, and cites a nineteenth-century travel diary in which a young woman complains that her breakfast didn't agree with her. Diaries, Humphreys explains, were often written to be shared with family and friends. Pocket diaries were as mobile as smartphones, allowing the diarist to record life in real time. Humphreys calls this chronicling, in both digital and nondigital forms, media accounting. The sense of self that emerges from media accounting is not the purely statistics-driven ?quantified self,? but the more well-rounded qualified self. We come to understand ourselves in a new way through the representations of ourselves that we create to be consumed.
