In this experiment, we find that features which model interaction and conversational behaviour contribute well to identifying sexual grooming behaviour in chat and forum text. Together with the obviously useful lexical features — which we find are more valuable if separated by who generates them — we achieve very successful results in identifying behavioural patterns which may characterise sexu...

This research applies the convergent insights of regulatory compliance and resource-dependence perspective to build a systematic framework of corporate compliance style (CCS thereafter). We use environmental regulation as the context of corporate compliance, and link corporate compliance with the levels of regulatory certainty and organizational nonmarket capabilities. We further develop a two ...

The classical Ellsberg experiment presents individuals with a choice problem in which the probability of winning a prize is unknown (ambiguous). In this paper we study how individuals make choices between gambles in which the ambiguity is in di↵erent dimensions: the winning probability, the amount of the prize and the payment date, and many combinations. While the decision-theoretic models acco...

Previous research has illustrated the importance of acquiring knowledge from authentic contexts; however, without full engagement, students’ learning performance might not be as good as expected. In this study, a Team Competition-based Ubiquitous Gaming approach was proposed for improving students’ learning effectiveness in authentic learning activities. An experiment on a natural science cours...

In this chapter we examine variation in the contents of supernatural minds across cultures and the social correlates of this variation. We first provide a sketch of how humans are capable of representing supernatural minds and emphasize the significance of the types of knowledge attributed to supernatural agents. We then argue that the contents of supernatural minds as represented cross-cultura...

We address the problem of identifying misbehaving nodes that refuse to forward packets in wireless multi-hop networks. We map the process of locating the misbehaving nodes to the classic Rényi-Ulam game of 20 questions. Compared to previous methods, our mapping allows the evaluation of node behavior on a per-packet basis, without the need for energy-expensive overhearing techniques or intensive...

Developmental psychology researchers examine the temporal relationships of social and communicative behaviors, such as how a child responds to a name call, to understand early typical and atypical development and to discover early signs of autism and developmental delay. These related behaviors occur together or within close temporal proximity, forming unique patterns and relationships of inter...

Instructional activities based on online discussion strategies have gained prevalence in recent years. Within this context, a crucial research topic is to design innovative and appropriate online discussion strategies that assist learners in attaining a deeper level of interaction and higher cognitive skills. By analyzing the process of online discussion in depth using a specific instructional ...

This research explains the importance of transculturality in social networking in a wide variety of activities of our daily life. We focus our analysis to online activities that use social richness, analyzing societies in Yakutia (A Russian Republic), Macau in China, Uberlândia in Brazil and Juarez City in Mexico, all with people descending from Japanese people. To this end, we performed survey...
