In this work, we consider the problem of detecting anomalous behaviour, and we present a novel approach allows classifying ”behaviour” either to be normal or abnormal by checking the p-value associated with the occurrence of the behaviour which is modelled following a binomial distribution within a discrete time model. The basic model for social networks is a graph. Over time, the graph underly...

Functional and structural neuroimaging of the human cingulate cortex has identified this region with emotion and social cognition and suggested that cingulate pathology may be associated with emotional and social behavioural disturbances. The importance of the cingulate cortex for emotion and social behaviour, however, has not been clear from lesion studies. Bilateral lesions in the cingulate c...

Social navigation is a way for users to navigate through social information such as resources and social annotation (tags). However, due to the growth of social networks, the user could be lost. To avoid this problem of disorientation, we try to adapt the social information through a recommendation technique by providing useful information according to the user’s needs. In this paper, we presen...

Behaviour in public good experiments is usually attributed partly to rational self-interest and partly to social norms and preferences. This paper examines if sensitivity to social desirability affects public good contribution and in what way. A pre-experimental measure of social desirability (SDS17) was used to match partners in a two-person public good game. Half the participants received exp...

This study examines the individuals’ participation intentions and behaviour on Social Networking Sites (SNSs). For this purpose, the Technology Acceptance Model (TAM) is utilized and extended in this study through the addition of “perceived social capital” construct aiming to increase its explanatory power and predictive ability in this context. Data collected from a survey of 1100 participants...

Visual motion, a critical cue in communication, can be manipulated and studied using video playback methods. A primary concern for the video playback researcher is the degree to which objects presented on video appear natural to the non-human subject. Here we argue that the quality of motion cues on video, as determined by the video's image presentation rate (IPR), are of particular importance ...

Nonadditive effects of group membership are generated when individuals respond differently to the same social environment and may alter predictions about how behavioural evolution will occur. Despite this importance, the relationship between an individual's behaviour in two different social contexts and how reciprocal interactions among individuals within groups influence group behaviour are po...

Previous studies have demonstrated similarities in gazing behaviour of dogs and humans, but comparisons under similar conditions are rare, and little is known about dogs' visual attention to social scenes. Here, we recorded the eye gaze of dogs while they viewed images containing two humans or dogs either interacting socially or facing away: the results were compared with equivalent data measur...

The social laws paradigm represents an important approach to the co-ordination of behaviour in multi-agent systems. In this paper we examine the relationship between social laws and rational behaviour, by which we mean behaviour that can be justified by a defensible argument. We describe how social laws have previously been defined and used within the context of Action-Based Alternating Transit...
