    Social media (SM) have enabled new forms of communication, interaction, and connectivity that affect individuals on a personal and professional level. But SM is a broad term that encompasses a wide range of technologies with both distinct and shared capabilities. In addition, while there is an agreed-upon definition of these systems, a comprehensive list of features and their affordances does not exist. Hence, this study sought to create a feature-level categorisation framework for analysing the use of social network sites (SNS). This categorisation was undertaken using the concept of affordances, which framed the high-level characteristics as well as distinct SNS features, to better understand the divergence in SNS capabilities and inform the study of different types of SM. The framework was created from an analysis of the literature on SNS affordances and a system investigation into three types of SNS (Facebook, YouTube and Twitter). The comprehensive review was undertaken using two families of SNS affordances (social and content affordances) identified in the literature to categorise and compare the platforms. The study reveals a diverse collection of features which afford behaviour in six areas of activity: profile building, social connectivity, social interactivity, content discovery, content sharing and content aggregation. Finally, the framework provides a basis from which the usage and management of SM within organisations can be more rigorously investigated

    Mapping an ancient historian in a digital age: the Herodotus Encoded Space-Text-Image Archive (HESTIA)

    Get PDF
    HESTIA (the Herodotus Encoded Space-Text-Imaging Archive) employs the latest digital technology to develop an innovative methodology to the study of spatial data in Herodotus' Histories. Using a digital text of Herodotus, freely available from the Perseus on-line library, to capture all the place-names mentioned in the narrative, we construct a database to house that information and represent it in a series of mapping applications, such as GIS, GoogleEarth and GoogleMap Timeline. As a collaboration of academics from the disciplines of Classics, Geography, and Archaeological Computing, HESTIA has the twin aim of investigating the ways geography is represented in the Histories and of bringing Herodotus' world into people's homes

    Broadcasting to the masses or building communities: Polish political parties’ online performance during 2011 elections in international perspective

    This paper analyses within the context of election contests the extent to which parties use the range of Web 2.0 tools, in particular social networking sites, weblogs and microblogs, in order to build communities online; we contrast this with the more traditional political use of the online environment for broadcasting. Using the 2011 Polish general election as a case study, we analyse the use of the online environment by all political parties, categorising features as offering a range of functions to serve visitors, from informing to allowing interaction. We also assess how different groups of visitors are targeted through different features or platforms. The data from the content analysis thus provides a rich picture of the online strategy of each party and the extent to which the Internet was used in the campaign. These data are supplemented by web cartography analysis which identifies the interlinkages between the websites of political parties, official information sources and the media. The cartography allows us to analyse the direction of traffic flow within the electoral websphere, the extent to which parties create open platforms with high levels of linkage to one another or if they maintain enclosed communities linking only to supportive sites. Overall our paper will provide an understanding of party election strategies during elections allowing discussion regarding the impact this might have on parties, media actors and voters. In particular we demonstrate how parties can use the range of web features to build communities of specific groups of visitors, in particular those with issue specific interests, those leaning towards supporting a party, and existing partisan campaigners. The use of these tools, we argue, can increase loyalty and lead to the conversion of supporters to activists. The paper leads into a discussion of how social networking tools have the potential to enhance the link between parties, members and supporters but that this depends on how the party utilises the online environment. Finally we aim to fit the Polish case study within a larger picture of political parties’ online performance during elections. Here we will compare our data on Poland with similar data which analysed the performance of parties in German 2009 general elections, parliamentary elections in Great Britain 2010 and French parliamentary election in 2012

    Wearing Many (Social) Hats: How Different are Your Different Social Network Personae?

    This paper investigates when users create profiles in different social networks, whether they are redundant expressions of the same persona, or they are adapted to each platform. Using the personal webpages of 116,998 users on About.me, we identify and extract matched user profiles on several major social networks including Facebook, Twitter, LinkedIn, and Instagram. We find evidence for distinct site-specific norms, such as differences in the language used in the text of the profile self-description, and the kind of picture used as profile image. By learning a model that robustly identifies the platform given a user's profile image (0.657--0.829 AUC) or self-description (0.608--0.847 AUC), we confirm that users do adapt their behaviour to individual platforms in an identifiable and learnable manner. However, different genders and age groups adapt their behaviour differently from each other, and these differences are, in general, consistent across different platforms. We show that differences in social profile construction correspond to differences in how formal or informal the platform is.Comment: Accepted at the 11th International AAAI Conference on Web and Social Media (ICWSM17

    Moving beyond 'refugeeness': problematising the 'refugee community organisation'

    Get PDF
    This paper explores processes of change and development within asylum seeker and refugee-led associations in Glasgow. I argue that adopting a life-cycle approach to association emergence and continuity (Werbner 1991a: 15) provides a more rounded and sophisticated understanding of not only the factors giving rise to such groups, but also of processes of change within groups. By problematising the ‘refugee community organisation’ label, I suggest that the focus on ‘refugeeness’ fails to attend to internal diversity, specifically relating to changing and differentiated immigration status within such associations. Exploring an externally constructed fictive unity using Werbner’s framework provides one way to challenge these effects. Rather than see this framework as made up of linear stages, I argue that groups move through and between stages of associative empowerment, ideological convergence and mobilisation simultaneously and that features differentiating stages may be co-present. This paper is relevant for policy-makers, practitioners and third sector organisations and can aid thinking about how to move beyond labels in approaching broader questions, practices and experiences of ‘settlement’, integration, belonging and social cohesion

    Citizen participation in news

    No full text
    The process of producing news has changed significantly due to the advent of the Web, which has enabled the increasing involvement of citizens in news production. This trend has been given many names, including participatory journalism, produsage, and crowd-sourced journalism, but these terms are ambiguous and have been applied inconsistently, making comparison of news systems difficult. In particular, it is problematic to distinguish the levels of citizen involvement, and therefore the extent to which news production has genuinely been opened up. In this paper we perform an analysis of 32 online news systems, comparing them in terms of how much power they give to citizens at each stage of the news production process. Our analysis reveals a diverse landscape of news systems and shows that they defy simplistic categorisation, but it also provides the means to compare different approaches in a systematic and meaningful way. We combine this with four case studies of individual stories to explore the ways that news stories can move and evolve across this landscape. Our conclusions are that online news systems are complex and interdependent, and that most do not involve citizens to the extent that the terms used to describe them imply

    Broadcasting to the masses or building communities: Polish political parties online communication during the 2011 election

    The professionalisation of political communication is an evolutionary process (Lilleker & Negrine, 2002), a process that adapts to trends in communication in order to better engage and persuade the public. One of the most dramatic developments in communication has been the move towards social communication via the Internet. It is argued to affect every area of public communication, from commercial advertising and public relations to education (Macnamara, 2010). It is no longer sufficient to have an online presence; we are now in an age of i-branding; with the ‘i’ standing for interactive. Yet, trends in online political electoral campaigning over recent years indicate a shallow adoption of Web 2.0 tools, features and platforms; limited interactivity; and managed co-production. The Internet is now embedded as a campaigning tool however, largely, the technologies are adapted to the norms of political communication rather than technologies impacting upon internal organizational structures, party relationships to members and supporters, or the content and style of their communication. We examine these themes, and develop them through a focus on the targeting and networking strategies of political parties, in more detail in the context of the Polish parliamentary election of 2011. Through a sophisticated content analysis and coding scheme our paper examines the extent to which parties use features that are designed to inform, engage, mobilise or allow interaction, which audiences they seek to communicate with and how these fit communication strategies. Comparing these findings with maps built from webcrawler analysis we build a picture of the strategies of the parties and the extent to which this links to short and long term political goals. This paper firstly develops our rationale for studying party and candidate use of the Internet during elections within the Polish context. Secondly we develop a conceptual framework which contrasts the politics as usual thesis (Margolis & Resnick, 2000) with arguments surrounding the social shaping of technologies (Lievrouw, 2006) and the impact on organisational adoption of communication technologies and post-Obama trends in Internet usage (Lilleker & Jackson, 2011) and posit that, despite the threats from an interactive strategy (Stromer-Galley, 2000) one would be expected within the context of a networked society (Van Dyjk, 2006). Following an overview of our methodology and innovative analysis strategy, we present our data which focuses on three key elements. Firstly we focus on the extent to which party and candidate websites inform, engage, mobilise or permit interaction (Lilleker et al, 2011). Secondly we assess the extent to which websites attract different visitor groups (Lilleker & Jackson, 2011) and build communities (Lilleker & Koc-Michalska, 2012). Thirdly we assess the reach strategies of the websites using Webcrawler technology which analyses the use of hyperlinks and whether parties lock themselves within cyberghettoes (Sunstein, 2007) or attempt to harness the power of the network (Benkler, 2006)
