Downloading culture: community building in a decentralized file-sharing collective

File-sharing collectives have significantly disrupted models of digital media distribution since their emergence and widespread popularization in the late 1990s. This study investigates how semi-anonymous and decentralized collectives construct their communities of practice. Conducting a case study of a private torrenting community, data were gathered via participant observation, interviews, and online postings (i.e., blogs and forums). Findings challenged dominant notions of opportunism, selfishness and task-oriented individualism advanced by Human–Computer Interaction scholars. Three key constructs were identified in private torrent community building: boundary construction, membership maintenance, and a sense of belonging and solidarity. Findings illustrate how a file-sharing community cultivates the formation of prosocial digital peers, fosters an affective approach to peer-to-peer collectives, and ultimately forges a downloading virtuoso community. This sisyphean, goal-oriented community seeks to create a comprehensive archive of media artifacts independent of and in opposition to dominant corporate platforms. The community demonstrates a downloading culture inspired by technological design, yet driven by trust and solidarity.     

Not for everyone: intra-organisational divides and the stratification of access to work–life policies

Prior research documented a number of factors pertaining to employees or to organisational cultures that can prevent employees from accessing employer-driven work–life policies (WLP). Our study focuses on factors originating in the jobs themselves. We conducted 98 in-depth employee interviews in two multinational companies based in Europe and led feedback sessions with human resources executives. Three mechanisms explained the observed stratification of access to WLP across jobs: (1) the intra-organisational digital divide prevented ‘less digital’ employees from collecting information about WLP on the intranet and thus impaired awareness of the policies; (2) the divide in worksite size prevented employees on smaller worksites from accessing childcare centres, sports or health facilities and (3) the divide in job types restricted access to WLP for specific occupations. The stratification of access to WLP was not strategically driven by human resources; rather the divides were largely unintentional. Our study uncovers inequalities of access originating in the jobs themselves and provides a theoretical integration of the various sets of factors that may promote or hinder employee awareness of WLP. Our findings suggest that organisations should strive to identify these inequalities and to provide ways to cope for these, for instance by offering other forms of support.     

Do the rich get digitally richer? Quantity and quality of support for digital engagement

This paper asks what predicts having access to and using social support networks that might help an individual in using the Internet. Following the course taken by the digital divide or digital inclusion research, this paper uses socio-cultural, socio-economic, social, and digital indicators to predict access to and the type of potential and actual social support networks that might help an individual in using the Internet. In addition, the paper examines the quality of the support received which is neglected in most investigations that mainly focus on quantitative indicators of support. The study draws on a representative survey conducted in the Netherlands; 1149 responses were obtained. The results show that while there are no real inequalities in access to and use of support, the quality of the support that people access is unequally distributed replicating existing patterns of disadvantage. Thus, access to support is another level at which the digital divide manifests and strengthens itself. Those who experience most problems online also seem to have the most difficulty obtaining high-quality support even when it is available, creating an even larger ‘gap’ between those who do and do not need support.     

Multiscale Bayesian state-space model for Granger causality analysis of brain signal

Modelling time-varying and frequency-specific relationships between two brain signals is becoming an essential methodological tool to answer theoretical questions in experimental neuroscience. In this article, we propose to estimate a frequency Granger causality statistic that may vary in time in order to evaluate the functional connections between two brain regions during a task. We use for that purpose an adaptive Kalman filter type of estimator of a linear Gaussian vector autoregressive model with coefficients evolving over time. The estimation procedure is achieved through variational Bayesian approximation and is extended for multiple trials. This Bayesian State Space (BSS) model provides a dynamical Granger-causality statistic that is quite natural. We propose to extend the BSS model to include the à trous Haar decomposition. This wavelet-based forecasting method is based on a multiscale resolution decomposition of the signal using the redundant à trous wavelet transform and allows us to capture short- and long-range dependencies between signals. Equally importantly it allows us to derive the desired dynamical and frequency-specific Granger-causality statistic. The application of these models to intracranial local field potential data recorded during a psychological experimental task shows the complex frequency-based cross-talk between amygdala and medial orbito-frontal cortex.     

Technological capital and digital divide among young people: an intersectional approach

This article explores the digital divide among young people in Spain by examining four traditional socio-demographic variables (gender, age, education and employment situation). It proposes the concept of ‘technological capital’ as a means to put people’s socioeconomic conditions of existence into relation with the different forms of accessing and using Information and Communication Technologies (ICT). Methodologically, a quantitative approach is taken, based on the National Statistics Institute’s survey of ICT Equipment in households, which makes use of both bivariate and multivariate analysis. Finally, a typology of young users of the Internet is proposed (1 – Digitally Excluded; 2 – Basic Users; 3 – Users in Mobility; 4 – Cyber Consumers; 5 – Cyber Experts) which takes into account the importance of technological capital, the socio-economic position and cultural resources of subjects in their incorporation of ICTs into their daily life.     

Digital survivance and Trickster humor: exploring visual and digital Indigenous epistemologies in the #NoDAPL movement

ABSTRACT

The decolonizing turn in the humanities and social sciences calls for scholarship that analyzes social media practices through the lens of Indigenous epistemologies. In this article, we model the ways that Indigenous epistemologies might contribute to theories of social media practices as we explore ways that the digital image can drive identification with and engagement in political acts. The article analyzes social media tropes circulated across various platforms among Indigenous communities and allies in relation to the #NoDAPL movement. We argue that attempting to analyze Native American traditions through Western theory will only work towards colonizing these Indigenous texts. Thus, whereas we employ insights from digital and visual methods of analysis (Highfield, T., & Leaver, T. (2016). Instagrammatics and digital methods: Studying visual social media, from selfies and GIFs to memes and emoji. Communication Research and Practice, 2(1), 47–62), we also highlight the strategic use of humor in the visual materials shared through various social media platforms utilizing the framework of the Trickster. We argue that the visual and digital phenomena we studied might best be understood as a form of digital survivance, drawing upon Anishinaabe scholar Gerald Vizenor [(1994). Manifest manners: Postindian warriors of survivance. Hanover, CT: Wesleyan University Press]. term ‘survivance’ as a portmanteau that combines ‘survival’ and ‘resistance’ in its characterization of Indigenous storytelling traditions. Whereas centering the Indigenous figure of the Trickster might suggest that social media has failed to live up to its promises, this epistemological approach also explains the hope that Indigenous communities hold in uniting via social media for what has been and continues to be a long-term battle for sovereignty and for the protection of the earth and all of its beings.     

电商平台自营和制造商直销的多渠道竞争策略研究

近年来电商平台自营产品和制造商开辟直销渠道已非常普遍。电商平台的自营行为，必然会产生与制造商销售渠道（通过平台销售的渠道或直销渠道）的竞争问题；制造商的直销行为，必然会产生与电商平台自营渠道的竞争问题。这种全新的渠道竞争行为非常值得研究，也是本文的研究核心。因此，运用博弈论的相关原理，本文得出并分析了不同情况下电商平台和制造商的博弈均衡策略。研究表明，当直销成本较低时，最终博弈均衡策略为：电商平台自营，制造商同时经营两条渠道；此时如果制造商的两条销售渠道竞争力都强，双方陷入囚徒困境，否则，电商平台利润改善，制造商利润降低。当直销成本适中时，最终博弈均衡策略为：电商平台自营，制造商只直销；此时，如果制造商的两条销售渠道竞争力都强、或平台渠道竞争力适中且直销渠道竞争力强，双方陷入囚徒困境，否则，电商平台利润改善，制造商利润降低。当直销成本较高时，若直销渠道竞争力强，双方将陷入斗鸡博弈。否则，最终博弈均衡策略为：电商平台自营，制造商不直销；此时，电商平台利润会改善，制造商利润会下降。     

A ‘Tripadvisor’ for disability? Social enterprise and ‘digital disruption’ in Australia

ABSTRACT

We explore how social enterprises can use platform technologies to plug ‘informational gaps’ in the provision of disability services. Such gaps are made more apparent by policies promoting self-directed care as a means of giving service users more choice and control. We use a case study of a start-up social enterprise seeking to provide a TripAdvisor style service to examine the potential for social innovation to ‘disrupt’ current models of service. The case study suggests that any disruptive effects of such changes are not due to new digital technology per se, nor to novel platform business models, but rather rest in the manner in which the moral orders which justify current patterns of social disablement can be challenged by social innovation.     

Democracy,Redistribution, and Political Participation: Evidence From Sweden 1919–1938

In this paper, we compare how two different types of political regimes—direct versus representative democracy—redistribute income toward the relatively poor segments of society after the introduction of universal and equal suffrage. Swedish local governments are used as a testing ground since this setting offers a number of attractive features for a credible impact evaluation. Most importantly, we exploit the existence of a population threshold, which partly determined a local government's choice of democracy to implement a regression‐discontinuity design. The results indicate that direct democracies spend 40–60 percent less on public welfare. Our interpretation is that direct democracy may be more prone to elite capture than representative democracy since the elite's potential to exercise de facto power is likely to be greater in direct democracy after democratization.
