This study identifies two distinct conceptualizations of interactivity in the communication literature—the functional view and the contingency view. Although the functional view has predominated academic research on interactivity, this study operationalizes the contingency view in the context of an experiment designed to investigate the impression formation effects of interactivity in Web-based...

A feature model is a representation of the requirements in a given system abstracted at the feature level. Linking conceptual requirements in feature models to actual implementation artifacts provides for many advantages such as increased program comprehension, implementation completeness assessment, impact analysis, and reuse opportunities. However, in practice, as systems evolve, traceability...

Social support has been reliably related to physical health outcomes. However, the conceptual basis of such links needs greater development. In this article, I argue for a life-span perspective on social support and health that takes into account distinct antecedent processes and mechanisms that are related to measures of support over time. Such a view highlights the need to distinguish measure...

This paper analyses science policy resource allocation in the light of a comparison of the open innovation and Mode 2 new production of knowledge conceptual frameworks. It provides a brief historical review of the evolution of science funding and the application of the Haldane principle in the UK. The core of the paper analyses academic and business attitudes to university-industry links using ...

Morality and emotions are linked, but what is the nature of their correspondence? Many "whole number" accounts posit specific correspondences between moral content and discrete emotions, such that harm is linked to anger, and purity is linked to disgust. A review of the literature provides little support for these specific morality-emotion links. Moreover, any apparent specificity may arise fro...

A study was carried out to investigate the effects of prior knowledge on learning with a non-linear electronic document including an interactive conceptual map. Cognitive Load Theory was used as theoretical framework to investigate effects on cognitive load and disorientation in learning from non-linear documents. Forty-four future high school biology teachers were required to learn the multipl...

We investigated conceptual overlap between literature demonstrating links between adult facial width-to-height ratio (FWHR) and behavior and that demonstrating links between infant FWHR and temperament by investigating whether babyfaceness is associated with FWHR and behavior at both ages. Babyfaceness was positively correlated with FWHR in both infants and adults. Babyfaceness also was correla...

Although there has been a substantial effort to establish the beneficial effects of social support on health and well-being, relatively little work has focused on how social support influences physical health. This article outlines possible mechanisms through which support systems may influence the etiology of physical disease. I begin by reviewing research on the relations between social suppo...

To understand the mechanisms that underlie marketing communication support for product launches, the authors conduct an empirical study and propose a conceptual framework that depicts the relationships between informational/transformational or elaborational/relational messages and their effectiveness. The hypothesized message–communication and message–sales effect links are moderated by three c...
