The effectiveness of and adherence to eHealth interventions is enhanced by human support. However, human support has largely not been manualized and has usually not been guided by clear models. The objective of this paper is to develop a clear theoretical model, based on relevant empirical literature, that can guide research into human support components of eHealth interventions. A review of th...

Models of the mind are based on the idea that neuron microtubules can perform computation. From this point of view, information processing is the fundamental issue for understanding the brain mechanisms that produce consciousness. The cytoskeleton polymers could store and process information through their dynamic coupling mediated by mechanical energy. We analyze the problem of information tran...

Brain-computer interfaces (BCIs) provide a non-muscular communication channel for persons with severe motor impairments. Previous studies have shown that the aptitude with which a BCI can be controlled varies from person to person. A reliable predictor of performance could facilitate selection of a suitable BCI paradigm. Eleven severely motor impaired participants performed three sessions of a ...

This article discusses the role of evidence-based media advocacy in the promotion of tobacco control policies. Evidence is a driving force for campaigns seeking to implement a tobacco control policy. An effective campaign is based in evidence that demonstrates why a policy should be implemented, and what the potential benefits are. Media advocacy is the process of disseminating information thro...

We generalize the asymptotic capacity expression for very noisy communication channels to now include coloured noise. For the practical scenario of a non-optimal receiver, we consider the common case of a correlation receiver. Due to the central limit theorem and the cumulative characteristic of a correlation receiver, we model this channel noise as additive Gaussian noise. Then, the channel ca...

This research concentrates around the topic of the criminal exchange of child pornography material on the Internet. The existing scientific material on this criminal exchange lacks technical details that could help police detectives work more efficiently in child pornography cases. This paper specifies a new criminal exchange model of child pornography that describes (1) the current child porno...

This paper describes an experimental study of interactivity effects in electronically mediated feedback communication. Conversational interactivity is expected to be lower when pairs of subjects are using mixed communication media. Performance feedback is expected to be less successful when interactivity is reduced, especially when the properties of the communication environment violate the nor...

Three experiments explore several factors which influence information transmission when warning messages are passed from person to person. In Experiment 1, messages were passed down chains of participants using five different modes of communication. Written communication channels resulted in more accurate message transmission than verbal. In addition, some elements of the message endured furthe...

Communication in knowledge intensive firms involves perspective making and perspective taking within and between their communities of knowing. In this paper we look to science as an example of knowledge work in a community of knowing, and draw implications for the design of electronic communication systems and policies to support perspective making and perspective taking. The role of narrative ...
