From the fringes into mainstream politics: intermediary networks and movement-party coordination of a global anti-immigration campaign in Germany
Many liberal democracies have witnessed the rise of radical right parties and movements that threaten liberal values of tolerance and inclusion. Extremist movement factions may promote inflammatory ideas that engage broader publics, but party leaders face dilemmas of endorsing content from extremist origins. However, when that content is shared over larger intermediary networks of aligned supporters and media sites, it may become laundered or disconnected from its original sources so that parties can play it back as official communication. With a dynamic network analysis and various-time series analysis we tracked content flows from the German version of a global far-right anti-immigration campaign across different media platforms, including YouTube, Twitter, and collections of far-right and mainstream media sites. The analysis shows how content from the small extremist Identitarian Movement spread over expanding networks of low-level activists of the Alternative for Germany party and far-right alternative media sites. That network bridging enabled party leadership to launder the source of the content and roll out its own version of the campaign. As a result, national attention became directed to extremist ideas
No-Switching Quantum Key Distribution using Broadband Modulated Coherent Light
We realize an end-to-end no-switching quantum key distribution protocol using
continuous-wave coherent light. We encode weak broadband Gaussian modulations
onto the amplitude and phase quadratures of light beams at the Shannon's
information limit. Our no-switching protocol achieves high secret key rate via
a post-selection protocol that utilizes both quadrature information
simultaneously. We establish a secret key rate of 25 Mbits/s for a lossless
channel and 1 kbit/s, per 17 MHz of detected bandwidth, for 90% channel loss.
Since our scheme is truly broadband, it can potentially deliver orders of
magnitude higher key rates by extending the encoding bandwidth with higher-end
telecommunication technology.Comment: 5 pages, 3 figures, publishe
Citizen participation in news
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
Predicting Online and Offline Civic Participation among Young Czech Roma: The Roles of Resources, Community Perceptions and Social Norms
Roma in the Czech Republic represent a large ethnic minority that faces intolerance and social exclusion. This study aims to describe factors that boost civic participation among Roma adolescents and emerging adults. Specifically, it asks whether different factors apply to Roma and members of the majority, and whether different factors boost offline and online participation. Survey data were analysed from Roma (n = 157) and majority (n = 573) participants between the ages of 15 and 28. Hierarchical regression models suggested that certain factors (a sense of collective influence and peer participatory norm) predict all forms of civic participation, regardless of ethnicity. For Roma youth, in contrast with the majority, offline participation was associated with a perceived lack of opportunities and unmet needs in their communities, which suggests that their offline civic participation might be a reaction to perceived communal problems. Finally, a lack of education was identified as a major explanation for lower rates of online participation among Roma
Experimental characterization of continuous-variable entanglement
We present an experimental analysis of quadrature entanglement produced from a pair of amplitude squeezed beams. The correlation matrix of the state is characterized within a set of reasonable assumptions, and the strength of the entanglement is gauged using measures of the degree of inseparability and the degree of Einstein-Podolsky-Rosen (EPR) paradox. We introduce controlled decoherence in the form of optical loss to the entangled state, and demonstrate qualitative differences in the response of the degrees of inseparability and EPR paradox to this loss. The entanglement is represented on a photon number diagram that provides an intuitive and physically relevant description of the state. We calculate efficacy contours for several quantum information protocols on this diagram, and use them to predict the effectiveness of our entanglement in those protocols
The democratic interface: technology, political organization, and diverging patterns of electoral representation
Democracies are experiencing historic disruptions affecting how people engage with core institutions such as the press, civil society organizations, parties, and elections. These processes of citizen interaction with institutions operate as a democratic interface shaping self-government and the quality of public life. The electoral dimension of the interface is important, as its operation can affect all others. This analysis explores a growing left-right imbalance in the electoral connection between citizens, parties, elections, and government. This imbalance is due, in part, to divergent left-right preferences for political engagement, organization, and communication. Support on the right for clearer social rules and simpler moral, racial and nationalist agendas are compatible with hierarchical, leader-centered party organizations that compete more effectively in elections. Parties on the left currently face greater challenges engaging citizens due to the popular meta-ideology of diversity and inclusiveness and demands for direct or deliberative democracy. What we term connective parties are developing technologies to perform core organizational functions, and some have achieved electoral success. However, when connective parties on the left try to develop shared authority processes, online and offline, they face significant challenges competing with more conventionally organized parties on the right
Social media in democratic transitions and consolidations: what can we learn from the case of Tunisia?
© 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group. The aim of this paper is to analyse the use of social media in the stages of uprising, democratic transition and democratic consolidation using the case study of Tunisia. While the impact of social media in uprisings has been widely documented in past research about the MENA region, Tunisia provides new evidence to the use of Internet in the processes of democratisation. Consequently, this research focuses in detail on the benefits but also the pitfalls of social media in transitions and consolidations. Data collection was based on interviews with Tunisian social media activists. The analysis is valuable to social media practitioners and researchers alike
