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 ...

BACKGROUND There are growing reasons to use both information and communication functions of learning technologies as part of clinical education, but the literature offers few accounts of such implementations or evaluations of their impact. This paper details the process of implementing a blend of online and face-to-face learning and teaching in a clinical education setting and it reports on the...

The theory of proof-of-principle triple-mode squeezing is proposed via spontaneous parametric six-wave mixing process in an atomic-cavity coupled system. Special attention is focused on the role of dressed state and nonlinear gain on triple-mode squeezing process. Using the dressed state theory, we find that optical squeezing and Autler-Towns splitting of cavity mode can be realized with nonlin...

Online communication media are being used increasingly for attempts to persuade message receivers. This paper presents a theoretical model that predicts outcomes of online persuasion based on the structure of primary and secondary goals message receivers hold toward the communication.
