The interrupted world: Surrealist disruption and altered escapes from reality

Following Breton’s writings on surreality, we outline how unexpected challenges to consumers’ assumptive worlds have the potential to alter how their escape from reality is experienced. We introduce the concept of ‘surrealist disruption’ to describe ontological discontinuities that disrupt the common-sense frameworks normally used by consumers and that impact upon their ability to suspend their disbeliefs and experience self-loss. To facilitate our theorization, we draw upon interviews with consumers about their changing experiences as viewers of the realist political TV drama House of Cards against a backdrop of disruptive real-world political events. Our analyses reveal that, when faced with a radically altered external environment, escape from reality changes from a restorative, playful experience to an uneasy, earnest one characterized by hysteretic angst, intersubjective sense-making and epistemological community-building. This reconceptualizes escapism as more emotionally multivalenced than previously considered in marketing theory and reveals consumers’ subject position to an aggregative social fabric beyond their control

‘I Don’t Trust the Phone; It Always Lies’:Trust and Information and Communication Technologies in Tanzanian Micro- and Small Enterprises

Despite its importance in African enterprise, the issue of ¿trust¿ is absent in information and communication technology for development scholarship. This article examines three case study subsectors of the Tanzanian economy to shed light on some of the complexities surrounding the sudden interface between traditional, established communication, and the increasing use of new information and communication technologies (ICTs). It seems from the case studies that, whereas mobile phones are indeed creating new forms of network in the twenty-first century, they are still far from being Africa's dominant form of network as Støvring (2004, 22) contends. The case studies reveal the overlap between social interaction and business in an African economy. Trust emerges as a common theme, and I discuss how important an issue it is in relation to the new form of communication that ICT provides for entrepreneurs in Africa. I suggest that, in relation to ICT in developing countries, trust might at this stage be separated from the more slippery concept of social capital that it is frequently associated with elsewhere. I then reflect on the implications of this for future research into ICT and its business and nonbusiness applications in developing countries. I conclude by suggesting that the need for direct, personal interaction through face-to-face contact¿a traditional pre-ICT aspect of African business culture¿is unlikely to change for some tim

A class of theory-decidable inference systems

Tableau d’honneur de la Faculté des études supérieures et postdoctorales, 2004-2005Dans les deux dernières décennies, l’Internet a apporté une nouvelle dimension aux communications. Il est maintenant possible de communiquer avec n’importe qui, n’importe où, n’importe quand et ce, en quelques secondes. Alors que certains systèmes de communication distribués, comme le courriel, le chat, . . . , sont plutôt informels et ne nécessitent aucune sécurité, d’autres comme l’échange d’informations militaires ou encore médicales, le commerce électronique, . . . , sont très formels et nécessitent de très hauts niveaux de sécurité. Pour atteindre les objectifs de sécurité voulus, les protocoles cryptographiques sont souvent utilisés. Cependant, la création et l’analyse de ces protocoles sont très difficiles. Certains protocoles ont été montrés incorrects plusieurs années après leur conception. Nous savons maintenant que les méthodes formelles sont le seul espoir pour avoir des protocoles parfaitement corrects. Ce travail est une contribution dans le domaine de l’analyse des protocoles cryptographiques de la façon suivante: • Une classification des méthodes formelles utilisées pour l’analyse des protocoles cryptographiques. • L’utilisation des systèmes d’inférence pour la mod´elisation des protocoles cryptographiques. • La définition d’une classe de systèmes d’inférence qui ont une theorie décidable. • La proposition d’une procédure de décision pour une grande classe de protocoles cryptographiquesIn the last two decades, Internet brought a new dimension to communications. It is now possible to communicate with anyone, anywhere at anytime in few seconds. While some distributed communications, like e-mail, chat, . . . , are rather informal and require no security at all, others, like military or medical information exchange, electronic-commerce, . . . , are highly formal and require a quite strong security. To achieve security goals in distributed communications, it is common to use cryptographic protocols. However, the informal design and analysis of such protocols are error-prone. Some protocols were shown to be deficient many years after their conception. It is now well known that formal methods are the only hope of designing completely secure cryptographic protocols. This thesis is a contribution in the field of cryptographic protocols analysis in the following way: • A classification of the formal methods used in cryptographic protocols analysis. • The use of inference systems to model cryptographic protocols. • The definition of a class of theory-decidable inference systems. • The proposition of a decision procedure for a wide class of cryptographic protocols

Broken Theory

Broken Theory is a jettisoned collection of fragmentary writing, collected and collaged by new media artist, writer, musician, and theorist Alan Sondheim. Folding theoretical musings, text experiments, and personal confessions into a single textual flow, it examines the somatic foundations of philosophical theory and theorizing, discussing their relationships to the writer and body, and to the phenomenology of failure and fragility of philosophy’s production. Writing remains writing, undercuts and corrects itself, is always superseded, always produced within an untoward and bespoke silo – not as an inconceivable last word, but instead a broken contribution to philosophical thinking. The book is based on fragmentation and collapse, displacing annihilation and wandering towards a form of “roiling” within which the text teeters on the verge of disintegration. In other words, the writing develops momentary scaffoldings – writing shored up by the very mechanisms that threaten its disappearance. Broken Theory is prefaced by a text from Maria Damon and followed by an extensive interview with art historian Ryan Whyte

Lets Talk about Race: Identity, Chatbots, and AI

Why is it so hard for chatbots to talk about race? This work explores how the biased contents of databases, the syntactic focus of natural language processing, and the opaque nature of deep learning algorithms cause chatbots difficulty in handling race-talk. In each of these areas, the tensions between race and chatbots create new opportunities for people and machines. By making the abstract and disparate qualities of this problem space tangible, we can develop chatbots that are more capable of handling race-talk in its many forms. Our goal is to provide the HCI community with ways to begin addressing the question, how can chatbots handle race-talk in new and improved ways

A study of peer activity in the early years through a range of contextual frameworks

This report focuses on exploring peer activity in the early years through a range of contextual frameworks. The research is conducted within a children's centre that provides nursery education for children aged 3-4 years as defined by the Early Years Foundation Stage - EYFS (2007). Research rationale focuses on the notion of, 'reflexive co-construction' through 'sustained shared thinking' (Siraj-Blatchford, 2002, p10). In order to appreciate this concept more fully among peers, it is suggested that a robust pedagogy is required to enhance the practitioner's understanding of peer activity. It is argued that context and peer activity are inextricably linked. If we are to consider peer activity, then its relationship with context must be more fully studied and articulated than in previous discussions. From a socio-constructivist standpoint, the study applies four different, but complementary theoretical perspectives to more fully describe and analyse the social realities children encounter on a daily basis. These perspectives are, an ecological understanding of human development, distributed cognition, activity theory and situated action. Peer literature in the early years is both varied and confusing in terms of context and outcome. Because of this predicament, it is suggested that there is an opening for studying peer activity from a contextual viewpoint. The research applies a qualitative ethnographic and observational approach. Data is generated from documentation, observations of, and discussions with, children and staff and is analysed within the four identified theoretical perspectives. The application of distributed cognition, activity theory and situated action further illuminates how children use a range of strategies to engage with one another. The research argues that such interactions within differing contexts create unique opportunities for reflexive co-construction amongst the children themselves. What emerges from this work is a pedagogical model, relating to peers and 'reflexive co-construction', which provides another dimension to current early years educational documentation
