We propose and study a model for the interplay between two different dynamical processes -one for opinion formation and the other for decision making- on two interconnected networks A and B. The opinion dynamics on network A corresponds to that of the M-model, where the state of each agent can take one of four possible values (S = -2,-1, 1, 2), describing its level of agreement on a given issue...

The venerable dual and multiprocess models that have guided work on attitudes and social cognition for the past few decades (see Chaiken & Trope, 1999) have been challenged recently on one hand by those who claim that there is really only one fundamental process of judgment (e.g., Fishbein & Middlestadt, 1995; Kruglanski, Erb, Pierro, Mannetti, & Chun, this issue; Kruglanski & Thompson, 1999) a...

The aim of this paper is to show how the use of social networks may help users to behave as modelers they trust. Users are guided in this respect within the context of an existing Recommendation-Based Process Modeling Support System to which “social” features are added. Two kinds of social networks are used to this end: (1) a social network from a process model repository and (2) a social netwo...

This review explores social science analyses of diagnosis of childhood neurological disabilities. The paper moves through three sections, which capture the historical and conceptual trends within the literature. The first focuses on work identifying the need to communicate effectively with parents when giving a diagnosis, the second explores the role parents can play as "partners" or contributo...

Social networks can have asymmetric relationships. In the online social network Twitter, a follower receives tweets from a followed person but the followed person is not obliged to subscribe to the channel of the follower. Thus, it is natural to consider the dissemination of information in directed networks. In this work we use the mean-field approach to derive differential equations that descr...

This paper addresses one instance of software developers attending to their own work-related needs. Behind this paper lies our belief that one key to improving software development is to make it easier for the developers to work together. This perspective is shared by many (e.g. Boehm, 1981, 1987; DeMarco and Lister, 1988; DeMarco, 1995) and our purpose in this paper is to describe one site’s a...

A key challenge for social psychology is to identify unifying principles that account the complex dynamics of behaviour. We propose psychological relativity and its core mechanism comparison as one such principle. To support our proposal, we review recent evidence investigating basic processes underlying novel applications comparisons. Specifically, clarify determinants assimilation contrast, e...
