The Lifecycles of Apps in a Social Ecosystem

Apps are emerging as an important form of on-line content, and they combine aspects of Web usage in interesting ways --- they exhibit a rich temporal structure of user adoption and long-term engagement, and they exist in a broader social ecosystem that helps drive these patterns of adoption and engagement. It has been difficult, however, to study apps in their natural setting since this requires a simultaneous analysis of a large set of popular apps and the underlying social network they inhabit. In this work we address this challenge through an analysis of the collection of apps on Facebook Login, developing a novel framework for analyzing both temporal and social properties. At the temporal level, we develop a retention model that represents a user's tendency to return to an app using a very small parameter set. At the social level, we organize the space of apps along two fundamental axes --- popularity and sociality --- and we show how a user's probability of adopting an app depends both on properties of the local network structure and on the match between the user's attributes, his or her friends' attributes, and the dominant attributes within the app's user population. We also develop models that show the importance of different feature sets with strong performance in predicting app success.Comment: 11 pages, 10 figures, 3 tables, International World Wide Web Conferenc

The social, cosmopolitanism and beyond

First, this article will outline the metaphysics of ‘the social’ that implicitly and explicitly connects the work of lassical and contemporary cosmopolitan sociologists as different as Durkheim, Weber, Beck and Luhmann. In a second step, I will show that the cosmopolitan outlook of classical sociology is driven by exclusive differences. In understanding human affairs, both classical sociology and contemporary cosmopolitan sociology reflect a very modernist outlook of epistemological, conceptual, methodological and disciplinary rigour that separates the cultural sphere from the natural objects of concern. I will suggest that classical sociology – in order to be cosmopolitan – is forced (1) to exclude non-social and non-human objects as part of its conceptual and methodological rigour, and (2) consequently and methodologically to rule out the non-social and the non-human. Cosmopolitan sociology imagines ‘the social’ as a global, universal explanatory device to conceive and describe the non-social and non-human. In a third and final step the article draws upon the work of the French sociologist Gabriel Tarde and offers a possible alternative to the modernist social and cultural other-logics of social sciences. It argues for a inclusive conception of ‘the social’ that gives the non-social and non-human a cosmopolitan voice as well

Prestige, Performance and Social Pressure in Viral Challenge Memes: Neknomination, the Ice-Bucket Challenge and SmearForSmear as Imitative Encounters

This article examines social media challenges that emerged in 2013, focusing on Neknomination, the Ice-Bucket Challenge and SmearForSmear. We understand them as ‘viral challenge memes’ that manifest a set of consistent features, making them a distinctive phenomenon within digital culture. Drawing upon Tarde’s concept of the imitative-encounter, we highlight three central features: their basis in social belonging and participation; the role of prestigious people and groups in determining the spread of challenges; and the distinctive techniques of self-presentation undertaken by participants. Based upon focus group interviews, surveys and visual analysis we suggest that viral challenge memes are social practices that diffuse in a wave-like fashion. Negotiating tensions between the social and individual, imitation and innovation, continuity and change, viral challenge memes are best thought of as creative practices, rather than sheep-like acts of conformity, and affirm the usefulness of analytical principles drawn from Tarde

Locative media and data-driven computing experiments

Over the past two decades urban social life has undergone a rapid and pervasive geocoding, becoming mediated, augmented and anticipated by location-sensitive technologies and services that generate and utilise big, personal, locative data. The production of these data has prompted the development of exploratory data-driven computing experiments that seek to find ways to extract value and insight from them. These projects often start from the data, rather than from a question or theory, and try to imagine and identify their potential utility. In this paper, we explore the desires and mechanics of data-driven computing experiments. We demonstrate how both locative media data and computing experiments are ‘staged’ to create new values and computing techniques, which in turn are used to try and derive possible futures that are ridden with unintended consequences. We argue that using computing experiments to imagine potential urban futures produces effects that often have little to do with creating new urban practices. Instead, these experiments promote Big Data science and the prospect that data produced for one purpose can be recast for another and act as alternative mechanisms of envisioning urban futures

The new empiricism of the fractal fold: Rethinking monadology in digital times

A new configuration of social science is emerging in these digital times, as we tap into new kinds of data that trouble conventions regarding what constitutes the unit of analysis, and question the extent to which these data are owned or even correlated to a definitive organic and individuated subject customarily referred to as "human." These methodological shifts demand a more careful consideration of the historical lineage of empiricism and its relation to the history of science more generally. In this article, I track the historical mutations of monadology, an ontology well suited to empiricism in these digital times. Both Gilles Deleuze and Bruno Latour ascribe to variants of monadology in their proposals for a new empiricism, drawing extensively on the work of Gabriel Tarde (1843-1904), a French sociologist, judge, and author of the audacious post-humanist 1895 text Sociology and Monadology. In this article, I discuss how monadology helps us rethink research methods in these digital times. I argue that a fractal monadology re-assembles the fold with the digital, the continuous with the discrete, and ultimately offers a philosophical foundation for contemporary social science research

This other atmosphere: against human resources, Emoji, and devices

Frequently humans are invited to engage with modern visual forms: emoji, emoticons, pictograms. Some of these forms are finding their ways into the workplace, understood as augmentations to workplace atmospheres. What has been called the ‘quantified workplace’ requires its workers to log their rates of stress, wellbeing, their subjective sense of productivity on scale of 1-5 or by emoji, in a context in which HR professionals develop a vocabulary of Workforce Analytics, People Analytics, Human Capital Analytics or Talent Analytics, and all this in the context of managing the work environment or its atmosphere. Atmosphere is mood, a compote of emotions. Emotions are a part of a human package characterised as ‘the quantified self’, a self intertwined with - subject to but also compliant with - tracking and archiving. The logical step for managing atmospheres is to track emotions at a granular and largescale level. Through the concept of the digital crowd, rated and self-rating, as well as emotion tracking strategies, the human resource (as worker and consumer) engages in a new politics of the crowd, organised around what political philosopher Jodi Dean calls, affirmatively, ‘secondary visuality’, high circulation communication fusing together speech, writing and image as a new form. This is the visuality of communicative, or social media, capitalism. But to the extent that it is captured by HR, is it an exposure less to crowdsourced democracy, and more a stage in turning the employee into an on-the-shelf item in a digital economy warehouse, assessed by Likert scales? While HR works on new atmospheres of work, what other atmospheres pervade the context of labour, and can these be deployed in the generation of other types of affect, ones that work towards the free association of labour and life

Good Friends, Bad News - Affect and Virality in Twitter

The link between affect, defined as the capacity for sentimental arousal on the part of a message, and virality, defined as the probability that it be sent along, is of significant theoretical and practical importance, e.g. for viral marketing. A quantitative study of emailing of articles from the NY Times finds a strong link between positive affect and virality, and, based on psychological theories it is concluded that this relation is universally valid. The conclusion appears to be in contrast with classic theory of diffusion in news media emphasizing negative affect as promoting propagation. In this paper we explore the apparent paradox in a quantitative analysis of information diffusion on Twitter. Twitter is interesting in this context as it has been shown to present both the characteristics social and news media. The basic measure of virality in Twitter is the probability of retweet. Twitter is different from email in that retweeting does not depend on pre-existing social relations, but often occur among strangers, thus in this respect Twitter may be more similar to traditional news media. We therefore hypothesize that negative news content is more likely to be retweeted, while for non-news tweets positive sentiments support virality. To test the hypothesis we analyze three corpora: A complete sample of tweets about the COP15 climate summit, a random sample of tweets, and a general text corpus including news. The latter allows us to train a classifier that can distinguish tweets that carry news and non-news information. We present evidence that negative sentiment enhances virality in the news segment, but not in the non-news segment. We conclude that the relation between affect and virality is more complex than expected based on the findings of Berger and Milkman (2010), in short 'if you want to be cited: Sweet talk your friends or serve bad news to the public'.Comment: 14 pages, 1 table.

The thing about pain: The remaking of illness narratives in chronic pain expressions on social media

In this article, we analyse chronic pain narratives on Flickr and Tumblr. We focus on how, by incorporating visual and multimodal elements, chronic pain expressions in social media significantly extend and challenge the logic, function and effects of traditional ‘illness narratives’. We examine a sample of images and blogs related to chronic pain and formulate a typology of chronic pain expressions on these sites. Flickr brings a form of narrative immediacy, making the pain experience visible, eliciting empathy and marking chronicity. Tumblr lends itself to more networked forms of interaction through the circulation of multimodal memes, and support communities are built through humour and social criticism. We argue that new forms of mediation and social media dynamics transform pain narratives. This has implications for our understandings of the forms and formats of pain communication and offers new possibilities for communicating pain within and beyond clinical contexts

Exploring the transdisciplinary trajectory of suggestibility

Traditionally considered a deficiency in will power and rationality, suggestibility has proven a troublesome concept for psychology. It was forgotten, rediscovered, denounced, undermined experimentation and recently became the ambiguous issue at the centre of concern about child witness' credibility in sexual abuse cases. This paper traces the history of suggestibility to show how it raises the 'paradox of the psychosocial'. Drawing on the work of Deleuze and Stengers, and on interviews with legal practitioners, this paper demonstrates how suggestibility carries this paradox into theory, research and legal practice. It thereby opens up a transdisciplinary perspective, allowing for questions of power and knowledge to be asked as performative questions. In the spirit of a process-centred ontology for psychology, I argue that suggestibility constitutes a 'rhythm of problematization', a folding, giving a subversive insight into dynamics of subjectification and application, and offering new perspectives towards issues of children's credibility and protection
