We analyse the C anonymity protocol under the novel assumption that the attacker has independent knowledge on behavioural patterns of individual users. Under such conditions we study, reformulate and extend Reiter and Rubin’s notion of probable innocence, and provide a new formalisation for it based on the concept of protocol vulnerability. Accordingly, we establish new formal relationship...

‘The need to justify our beliefs to ourselves and our fellow agents subjects us to norms, and obedience to these norms produces a behavioural pattern that we must detect in others before confidently attributing beliefs to them. But there seems to be no occasion to look for obedience to an additional norm – the commandment to seek the truth. For – to return to the pragmatist doubt with which I b...

This paper analyzes pedestrians’ behavioral patterns in the pedestrianized shopping environment in the historical center of Barcelona, Spain. We employ a Bluetooth detection technique to capture a large-scale dataset of pedestrians’ behavior over a one-month period, including during a key sales period. We focused on comparing particular behaviors before, during, and after the discount sales by ...

We study a class of large-group, noncooperative, iterated market entry games with complete information, binary choices, and asymmetric players in which the incentive of each player to enter the market decreases the larger the number of entrants. Experimental results from two different studies show remarkable coordination on the aggregate level, which is accounted for successfully by the Nash eq...

Do the personality traits of our youth and our family background influence our health in later life? Do psychological and behavioral patterns contribute to the occurrence of cancer? For many, the idea that an apparently physical disease is linked to personality or psychological characteristics seems absurd. Yet, a large body of research literature has accumulated over the past several decades i...

Gamification of education is a recent trend, and early experiments showed promising results. Students seem not only to perform better, but also to participate more and to feel more engaged with gamified learning. However, little is known regarding how different students are affected by gamification and how their learning experience may vary. In this paper the authors present a study in which th...

We study if and how social preferences extend to risky environments. We provide experimental evidence from different versions of dictator games with risky outcomes, and establish that preferences that are exclusively based on ex post or on ex ante comparisons cannot generate the observed behavioral patterns. The more money decision-makers transfer in the standard dictator game, the more likely ...

A computational model of selective attention has been previously used to provide a concrete and comprehensive account for perceptual load findings in visual search tasks (Neokleous, Koushiou, Avraamides, & Schizas, 2009). Here, the same model was used to simulate findings from an experiment in which perceptual load effects were attributed to distractor dilution (Benoni & Tsal, 2010). By modelin...

Studies indicate that children believe that positive behaviors are more likely than negative ones to remain stable across time and situations. The present study assessed whether children hold such optimism equally regarding their own vs. others’ behavioral patterns. Thirty five-year-olds answered questions about the extent to which they viewed themselves as having various positively, neutrally,...

The purposes of this study were to provide a game-based anti-phishing lesson to 110 elementary school students in Taiwan, explore their learning behavioral patterns, and investigate the effects of the flow states on their learning behavioral patterns and learning achievement. The study recorded behaviour logs, and applied a preand post-test on phishing knowledge and a flow state measurement to ...
