This paper describes mathematical models for network evolution when ties (edges) are directed and the node set is xed. Each of these models implies a speci c type of departure from the standard null binomial model. We provide statistical tests that, in keeping with these models, are sensitive to particular types of departures from the null. Each model (and associated test) discussed follows dir...

Computer programming is a part of the curriculum in computer science education, and high drop rates for this subject are a universal problem. Development of metacognitive skills, including the conceptual framework provided by socio-cognitive theories that afford reflective thinking, such as actively monitoring, evaluating, and modifying one’s thinking, has been identified as important for novic...

Many simulators today contain traditional opponents and lack an asymmetric insurgent style adversary. InsurgiSim prototypes an embeddable testbed containing a threat network of agents that one can easily configure and deploy for training and analysis purposes. The insurgent network was constructed inside a socio-cognitive agent framework (FactionSim-PMFserv) that includes: (a) a synthesis of be...

Communication is not as smooth a process as current pragmatic theories depict it. In Rapaport’s words “We almost always fail [...]. Yet we almost always nearly succeed: This is the paradox of communication” (Rapaport 2003: 402). This paper claims that there is a need for an approach that is able to explain this “bumpy road” by analyzing both the positive and negative features of the communicati...

Herbert H. Clark’s Joint Action Theory (JAT) has been groundbreaking for understanding the social and cognitive mechanisms that allow people to effectively coordinate joint actions in conversational, face-to-face settings. Using a method we call “Pair Analytics,” we have extended the application of JAT to the study of analytical reasoning in computer-mediated, human-to-human interactions. Pair ...

Characterising how socio-cognitive abilities develop has been crucial to understanding the wider development of typically developing children. It is equally central to understanding developmental pathways in children with intellectual disabilities such as Down's syndrome. While the process of acquisition of socio-cognitive abilities in typical development and in autism has received considerable...

Purpose This paper aims to study the influence of procurement on the performance of integrated design teams. Design/methodology/approach The research paradigm is based on Russian socio-constructivist approach to activity theory. Activity theory, as opposed to natural or social science, is a design science approach that focuses on the context aspect of project. A triangulation of qualitative res...

This presentation has the character of a position paper. The author attempts to the identification and specification of socio-cognitive engineering as to a new field of research and, in parallel, as to a new systemic but redefined engineering approach which is based on interdisciplinary integrated paradigms applied to the domains of cognitive and social sciences together. The concepts of an abs...

A comprehensive pragmatic theory will certainly have to address both these issues. In the search for such a comprehensive view of pragmatics a question immediately arises: how are socio-pragmatics and cognitive pragmatics related? One answer given in the literature is that the two domains are separate and socio-pragmatics controls cognitive pragmatics in the sense that socio-pragmatic entities ...
