In the early 21st Century, with the phenomenon of digital convergence, the consecration of Web 2.0, the decrease of the cost of cameras and video recorders, the proliferation of mobile phones, laptops and wireless technologies, we witness the arising of a new wave of media, of an informal, personal and at times “minority” nature, facilitating social networks, a culture of fans, of sharing and remix. As digital networks become fully and deeply intricate in our experience, the idea of “participation” arises as one of the most complex and controversial themes of the contemporary critical discourse, namely in what concerns contemporary art and new media art. However, the idea of “participation” as a practice or postulate traverses the 20th century art playing an essential role in its auto-critic, in questioning the concept of author, and in the dilution of the frontiers between art, “life” and society, emphasizing the process, the everyday and a community sense. As such, questioning the new media art in light of a “participatory art” (Frieling, 2008) invokes a double gaze simultaneously attentive to the emerging figures of a “participatory aesthetics” in digital arts and of the genealogy in which it is included. In fact, relating the new media art with the complex and paradoxical phenomenon of “participation” allows us to, on the one hand, avoid “digital formalism” (Lovink, 2008) and analyse the relations between digital art and contemporary social movements; on the other hand, this angle of analysis contributes to reinforce the dialogue and the links between digital art and contemporary art, questioning the alleged frontiers that separate them.

Social networks offer horizontal integration for any mobile platform providing app users with a convenient single sign-on point. Nonetheless, there are growing privacy concerns regarding its use. These vulnerabilities trigger alarm among app developers who fight for their user base: While they are happy to act on users’ information collected via social networks, they are not always willing to sacrifice their adoption rate for this goal. So far, understanding of this trade-off has remained ambiguous. To fill this gap, we employ a discrete choice experiment to explore the role of Facebook Login and investigate the impact of accompanying requests for different information items / actions in the mobile app adoption process. We quantify users’ concerns regarding these items in monetary terms. Beyond hands-on insights for providers, our study contributes to the theoretical discourse on the value of privacy in the growing world of Social Media and mobile web.

Information and multimedia technologies that have been developed during the past couple of years provided new e-tools to memory institutions (viz. museum, libraries, galleries, etc.), reviving the valuable treasure made by generation of people. Digital libraries (DLs) are such powerful contemporary tools for cultural heritage presentation, preservation and archiving. However, DLs power will in-crease significantly if they use mechanisms for ubiquitous sharing of their e-artefacts and they distribute attractive content in the social networks, reflecting community demands and needs. This paper presents a service for automatic sharing of iconographical artefacts and full collections from the Bulgarian Iconographical Digital Library to selected Facebook communities. In this case the service will be used for widely promotion of knowledge about East-Christian Iconographical Art and Culture, but I could be used not only for this and not only in this domain.

A primary goal of context-aware systems is delivering the right information at the right place and right time to users in order to enable them to make effective decisions and improve their quality of life. There are three key requirements for achieving this goal: determining what information is relevant, personalizing it based on the users’ context (location, preferences, behavioral history etc.), and delivering it to them in a timely manner without an explicit request from them. These requirements create a paradigm that we term as “Proactive Context-aware Computing”. Most of the existing context-aware systems fulfill only a subset of these requirements. Many of these systems focus only on personalization of the requested information based on users’ current context. Moreover, they are often designed for specific domains. In addition, most of the existing systems are reactive - the users request for some information and the system delivers it to them. These systems are not proactive i.e. they cannot anticipate users’ intent and behavior and act proactively without an explicit request from them. In order to overcome these limitations, we need to conduct a deeper analysis and enhance our understanding of context-aware systems that are generic, universal, proactive and applicable to a wide variety of domains. To support this dissertation, we explore several directions. Clearly the most significant sources of information about users today are smartphones. A large amount of users’ context can be acquired through them and they can be used as an effective means to deliver information to users. In addition, social media such as Facebook, Flickr and Foursquare provide a rich and powerful platform to mine users’ interests, preferences and behavioral history. We employ the ubiquity of smartphones and the wealth of information available from social media to address the challenge of building proactive context-aware systems. We have implemented and evaluated a few approaches, including some as part of the Rover framework, to achieve the paradigm of Proactive Context-aware Computing. Rover is a context-aware research platform which has been evolving for the last 6 years. Since location is one of the most important context for users, we have developed ‘Locus’, an indoor localization, tracking and navigation system for multi-story buildings. Other important dimensions of users’ context include the activities that they are engaged in. To this end, we have developed ‘SenseMe’, a system that leverages the smartphone and its multiple sensors in order to perform multidimensional context and activity recognition for users. As part of the ‘SenseMe’ project, we also conducted an exploratory study of privacy, trust, risks and other concerns of users with smart phone based personal sensing systems and applications. To determine what information would be relevant to users’ situations, we have developed ‘TellMe’ - a system that employs a new, flexible and scalable approach based on Natural Language Processing techniques to perform bootstrapped discovery and ranking of relevant information in context-aware systems. In order to personalize the relevant information, we have also developed an algorithm and system for mining a broad range of users’ preferences from their social network profiles and activities. For recommending new information to the users based on their past behavior and context history (such as visited locations, activities and time), we have developed a recommender system and approach for performing multi-dimensional collaborative recommendations using tensor factorization. For timely delivery of personalized and relevant information, it is essential to anticipate and predict users’ behavior. To this end, we have developed a unified infrastructure, within the Rover framework, and implemented several novel approaches and algorithms that employ various contextual features and state of the art machine learning techniques for building diverse behavioral models of users. Examples of generated models include classifying users’ semantic places and mobility states, predicting their availability for accepting calls on smartphones and inferring their device charging behavior. Finally, to enable proactivity in context-aware systems, we have also developed a planning framework based on HTN planning. Together, these works provide a major push in the direction of proactive context-aware computing.

Il progetto di tesi nasce dalla volontà di far luce sul rapporto tra il medium fotografico e la nozione di nuova oscenità, teorizzata e disseminata nei suoi scritti da Jean Baudrillard. Nozione che – se intesa nell’accezione proposta dal filosofo francese, ovvero l’oscenità del visibile, del troppo visibile, del più visibile del visibile – ben si adatta a dettagliare i concetti di trasparenza e di visibilità peculiari della società attuale, costantemente impegnata nel mettere a nudo se stessa attraverso i social media in nome della cosiddetta ideologia della post-privacy. Incoraggiando una continua violazione della sfera del segreto, tale ideologia favorirebbe, infatti, la progressiva diminuzione dello scarto tra ciò che può essere reso di dominio pubblico e ciò che invece, tradizionalmente, sarebbe dovuto appartenere all’ambito del privato. Un andamento generale della cultura, quello appena delineato, che si è imposto capillarmente a cavallo di millennio, accelerato dalla nascita del World Wide Web, del quale la fotografia riesce a farsi promotrice oltre che sommo interprete, contribuendo – anche in virtù di un’innovata condizione tecnologica– al compimento della visibilità e della trasparenza totale. Nel corso della trattazione, la nozione “aggiornata” di osceno sarà, dunque, assurta a strumento euristico utile a tracciare gli svolgimenti paralleli della pratica fotografica nei campi delle arti visive, della moda e dei social media, in un arco temporale che va dall’inizio degli anni Novanta a oggi. Uno strumento attraverso cui connettere autori di riferimento, rileggerne alcuni e candidarne di nuovi tra quanti, allargando il “campo del fotografabile” teorizzato da Pierre Bourdieu, profanano la soglia del privato e portano alla ribalta i risvolti banali e ordinari della quotidianità, fino a quelli intimi, tragici, inquietanti, perturbanti o addirittura nefandi, favorendo così la concretizzazione di quel “bordello senza muri” che secondo Marshall McLuhan è il mondo nell’età fotografica.

Sosiaalinen media viittaa verkkopalveluihin, joiden toiminta perustuu käyttäjien ja käyttäjäyhteisöjen aktiiviseen sosiaaliseen vuorovaikutukseen. Matkapuhelimien kautta sosiaalinen media on liikkeellä ja pitää käyttäjät yhdessä ajasta ja paikasta riippumatta. Sosiaalisen median vetovoima perustuu siihen, että ihmiset jakavat tietoja, kuvia, videota ja ääntä sekä kommentoivat ja jatkavat viestiketjuja. Yhdessä ja liikkeellä -kirja tarkastelee sosiaalisen median uusinta ilmiötä, videoiden jakamista kännykkäpalvelun kautta. Mobiilit videot voivat kertoa jaetuista elämyksistä, konserteista, benji-hypyistä tai jazz-festivaalin vessajonosta. Liikkuva kuva kertoo usein enemmän kuin useampi valokuva, ja monen käyttäjän videokuva samasta tapahtumasta voi jo kertoa monipolvisen tarinan. Yhdessä ja liikkeellä esittelee Mobile Social Media -tutkimushankkeen tuloksia. Tavoitteena on ollut tutkia, millaiset tekijät tukevat mobiilin sosiaalisen median käyttöä ja miten sosiaalista mediaa hyödynnetään matkapuhelimilla, miten sosiaalisen median yhteisö voi muodostaa kännykkävideoista yhteisen tarinan, millaisia teknologisia haasteita mobiilin sosiaalisen median käytölle on. Tutkimushanke on CAT - Culture Art and Technology -verkoston yhteistyötä. Verkostoon kuuluvat Aalto-yliopiston, Tampereen teknillisen yliopiston ja Turun yliopiston Porin yksiköt.

In the beginning of its 10th year of existence Facebook has engaged and connected 1.2 billion monthly active users. This article-based dissertation Disconnect.Me – User Engagement and Facebook approaches this engagement from the opposite direction: disconnection. The research articles focus on social media specific phenomena including leaving Facebook, tactical media works such as Web 2.0 SuicideMachine, memorializing dead Facebook users and Facebook trolling. The media theoretical framework for this study is built around affect theory, software studies, biopolitics as well as different critical studies of new media. The argument is that disconnection is a necessary condition of social media connectivity and exploring social media through disconnection – as an empirical phenomenon, future potential and theoretical notion – helps us to understand how users are engaged with social media, its uses and subsequent business models. The results of the study indicate that engagement is a relation that precedes user participation, a notion often used to conceptualize social media. Furthermore, this engagement turns the focus from users’ actions towards the platform and how the platform actively controls users and their behavior. Facebook aims to engage new users and maintain the old ones by renewing its platform and user interface. User engagement with the platform is thus social but also technical and affective. When engaged, the user is positioned to algorithmic connectivity where machinc processes mine user data. This data is but sold also used to affect and engage other users. In the heart of this study is the notion that our networked engagements matter and disconnection can bring us to the current limits of network culture.

Despite their growing importance, the political effectiveness of social media remains understudied. Drawing on and updating resource mobilization theory and political process theory, this article considers how social media make “political engagement more probable,” and the determinants of success for online social movements. It does so by examining the mainstreaming of the Canadian “user rights” copyright movement, focusing on the Fair Copyright for Canada Facebook page, created in December 2007. This decentralized, grassroots, social media-focused action – the first successful campaign of its kind in Canada and one of the first in the world – changed the terms of the Canadian copyright debate and legitimized Canadian user rights. As this case demonstrates, social media have changed the type and amount of resources needed to create and sustain social movements, creating openings for new groups and interests. Their success, however, remains dependent on the political context within which they operate.

L’avénement des réseaux sociaux, tel que Facebook, MySpace et LinkedIn, a fourni une plateforme permettant aux individus de rester facilement connectés avec leurs amis, leurs familles ou encore leurs collègues tout en les encourageant activement à partager leurs données personnelles à travers le réseau. Avec la richesse des activités disponibles sur un réseau social, la quantité et la variété des informations personnelles partagées sont considérables. De plus, de part leur nature numérique, ces informations peuvent être facilement copiées, modifiées ou divulguées sans le consentement explicite de leur propriétaire. Ainsi, l’information personnelle révélée par les réseaux sociaux peut affecter de manière concrète la vie de leurs utilisateurs avec des risques pour leur vie privée allant d’un simple embarras à la ruine complète de leur réputation, en passant par l’usurpation d’identité. Malheureusement, la plupart des utilisateurs ne sont pas conscients de ces risques et les outils mis en place par les réseaux sociaux actuels ne sont pas suffisants pour protéger efficacement la vie privée de leurs utilisateurs. En outre, même si un utilisateur peut contrôler l’accès à son propre profil, il ne peut pas contrôler ce que les autres révèlent à son sujet. En effet, les “amis” d’un utilisateur sur un réseau social peuvent parfois révéler plus d’information à son propos que celui-ci ne le souhaiterait. Le respect de la vie privée est un droit fondamental pour chaque individu. Nous pré- sentons dans cette thèse une approche qui vise à accroître la prise de conscience des utilisateurs des risques par rapport à leur vie privée et à maintenir la souveraineté sur leurs données lorsqu’ils utilisent un réseau social. La première contribution de cette thèse réside dans la classification des risques multiples ainsi que les atteintes à la vie privée des utilisateurs d’un réseau social. Nous introduisons ensuite un cadre formel pour le respect de la vie privée dans les réseaux sociaux ainsi que le concept de politique de vie privée (UPP). Celle-ci définie par l’utilisateur offre une manière simple et flexible de spécifier et communiquer leur attentes en terme de respect de la vie privée à d’autres utilisateurs, tiers parties ainsi qu’au fournisseur du réseau social. Par ailleurs, nous dé- finissons une taxonomie (possiblement non-exhaustive) des critères qu’un réseau social peut intégrer dans sa conception pour améliorer le respect de la vie privée. En introduisant le concept de réseau social respectueux de la vie privée (PSNS), nous proposons Privacy Watch, un réseau social respectueux de la vie privée qui combine les concepts de provenance et d’imputabilité afin d’aider les utilisateurs à maintenir la souveraineté sur leurs données personnelles. Finalement, nous décrivons et comparons les différentes propositions de réseaux sociaux respectueux de la vie privée qui ont émergé récemment. Nous classifions aussi ces différentes approches au regard des critères de respect de la vie privée introduits dans cette thèse.

The first Speak Good English Movement, SGEM, took place in 2000, and has been organized annually ever since. Speaking a “standard” form of English is considered to bring increased personal power. However, the SGEM wants the Singaporeans to use “standard” English in their private life as well. A decade after the beginning of the campaign, a Speak Good Singlish Movement was started. Based on studies of language and identity, it is understandable why some Singaporeans might feel the SGEM threatens their identity. However, the reactions towards the campaign are mainly positive. For the purposes of this analysis, Twitter messages, Facebook pages, and newspaper articles from The Straits Times were collected. The SGEM has hailed both direct and indirect praise and criticism in both social and traditional media: Five newspaper articles praise the campaign while five criticize it; the results are nine and seven respectively for social media. This thesis looks at reactions towards the SGEM in both social and traditional media, analyzes how these reactions might relate to the ideas of the power of language, its variety and the relation of language and identity.

For those who have read even one of my musings, it will come as no surprise that I find Facebook, Twitter, social networking sites (SNS), and the rest of Webology less than inspiring. If you had read nothing other than the screed I blathered about Google a few columns back, you’d know that I find all this talk about the Web replacing libraries more than a little silly; I find it downright idiotic. Still, one must keep an open mind.
