Geo-located Twitter as the proxy for global mobility patterns
In the advent of a pervasive presence of location sharing services
researchers gained an unprecedented access to the direct records of human
activity in space and time. This paper analyses geo-located Twitter messages in
order to uncover global patterns of human mobility. Based on a dataset of
almost a billion tweets recorded in 2012 we estimate volumes of international
travelers in respect to their country of residence. We examine mobility
profiles of different nations looking at the characteristics such as mobility
rate, radius of gyration, diversity of destinations and a balance of the
inflows and outflows. The temporal patterns disclose the universal seasons of
increased international mobility and the peculiar national nature of overseen
travels. Our analysis of the community structure of the Twitter mobility
network, obtained with the iterative network partitioning, reveals spatially
cohesive regions that follow the regional division of the world. Finally, we
validate our result with the global tourism statistics and mobility models
provided by other authors, and argue that Twitter is a viable source to
understand and quantify global mobility patterns.Comment: 17 pages, 13 figure
Elite Tweets: Analysing the Twitter Communication Patterns of Labour Party Peers in the House of Lords
The micro-blogging platform Twitter has gained notoriety for its status as both a communication channel between private individuals, and as a public forum monitored by journalists, the public, and the state. Its potential application for political communication has not gone unnoticed; politicians have used Twitter to attract voters, interact with constituencies and advance issue-based campaigns. This article reports on the preliminary results of the research teamâs work with 21 peers sitting on the Labour frontbench. It is based on the monitoring and archival of the peersâ activity on Twitter for a period of 100 days from 16th May to 28th September 2012. Using a sample of more than 4,363 tweets and a mixed methodology combining semantic analysis, social network analysis and quantitative analysis, this paper explores the peersâ patterns of usage and communication on Twitter. Key findings are that as a tweeting community their behavior is consistent with others, however there is evidence that a coherent strategy is lacking. Labour peers tend to work in ego networks of self-interest as opposed to working together to promote party polic
@THEVIEWER: Analyzing the offline and online impact of a dedicated conversation manager in the newsroom of a public broadcaster
This study is built around the appointment of a dedicated âconversation managerâ at the Flemish public broadcaster VRT. We focus on (1) the impact of the conversation manager on Twitter activity of the viewers and (2) the impact of the tweeting audience in the newsroom. Our framework combines journalistic as well as social media logics in Bourdieuâs field framework, for which we combine Twitter data and newsroom inquiry. The network analysis of Twitter activity shows the impact of the conversation manager, although his activities are primarily guided by traditional journalistic values. In turn, the tweeting audience impacts newsroom practices, predominantly as an indicator of audience appreciation. To conclude, social media data further complicate the definition and understanding of âthe public.
Does Campaigning on Social Media Make a Difference? Evidence from candidate use of Twitter during the 2015 and 2017 UK Elections
Social media are now a routine part of political campaigns all over the
world. However, studies of the impact of campaigning on social platform have
thus far been limited to cross-sectional datasets from one election period
which are vulnerable to unobserved variable bias. Hence empirical evidence on
the effectiveness of political social media activity is thin. We address this
deficit by analysing a novel panel dataset of political Twitter activity in the
2015 and 2017 elections in the United Kingdom. We find that Twitter based
campaigning does seem to help win votes, a finding which is consistent across a
variety of different model specifications including a first difference
regression. The impact of Twitter use is small in absolute terms, though
comparable with that of campaign spending. Our data also support the idea that
effects are mediated through other communication channels, hence challenging
the relevance of engaging in an interactive fashion
Public Fora Purpose: Analyzing Viewpoint Discrimination on the Presidentâs Twitter Account
Today, protectable speech takes many forms in many spaces. This Note is about the spaces. This Note discusses whether President Donald J. Trumpâs personal Twitter account functions as a public forum, and if so, whether blocking constituents from said account amounts to viewpoint discriminationâa First Amendment freedom of speech violation. Part I introduces the core legal devices and doctrines that have developed in freedom of speech jurisprudence relating to issues of public fora. Part II analyzes whether social media generally serves as public fora, whether the Presidentâs personal Twitter account is a public forum, and whether his recent habit of blocking constituents from that account amounts to viewpoint discrimination. In doing so, Part II also addresses the applicability of the recent decision from the U.S. District Court for the Eastern District of Virginia, Davison v. Loudoun County Board of Supervisorsâwherein a local county government official was held to have engaged in viewpoint discrimination for banning a constituent from her personal social media accountâto the Knight First Amendment Institute at Columbia Universityâs pending case against the President for the same. Part III then suggests multiple approaches for courts to analyze these claims, while taking account of an analytical mismatch that occurs when trying to apply the Davison case to the case brought against the President
Seeing the smart city on Twitter: Colour and the affective territories of becoming smart
This paper pays attention to the immense and febrile field of digital image files which picture the smart city as they circulate on the social media platform Twitter. The paper considers tweeted images as an affective field in which flow and colour are especially generative. This luminescent field is territorialised into different, emergent forms of becoming âsmartâ. The paper identifies these territorialisations in two ways: firstly, by using the data visualisation software ImagePlot to create a visualisation of 9030 tweeted images related to smart cities; and secondly, by responding to the affective pushes of the image files thus visualised. It identifies two colours and three ways of affectively becoming smart: participating in smart, learning about smart, and anticipating smart, which are enacted with different distributions of mostly orange and blue images. The paper thus argues that debates about the power relations embedded in the smart city should consider the particular affective enactment of being smart that happens via social media. More generally, the paper concludes that geographers must pay more attention to the diverse and productive vitalities of social media platforms in urban life and that this will require experiment with methods that are responsive to specific digital qualities
Hunched over their laptops: phenomenological perspectives on citizen journalism
Donald Matheson (2003) writes of war correspondents âscowling at their notebooksâ, and this is not meant as caricature but the corporeal expression of an epistemological orientation to the world in which facts have to be wrestled into submission. This article takes a phenomenological approach to ask whether there is a distinct orientation of citizen journalism and blogging, exploring the corporeal, temporal and spatial aspects of non-professional practices of media production. Hunching over a laptop suggests an epistemology in which facts and opinions are urgent and potentially subversive, though it is also tied to the romanticised individualism with which citizen journalism in particular is associated
