Creative conceptual change involves (a) the construction of new concepts and of coherent belief systems, or theories, relating these concepts, and (b) the modification and extrapolation of existing concepts and theories in novel situations. I discuss these and other types of conceptual change, and present computational models of constructive and extrapolative processes in creative conceptual ch...

The problem treated here is to determinethe viscosity effect on stresses, temperature change and chemical potential in a circular plate. The mathematical formulation is applied to two theories of thermoelastic diffusion developed by Sherief et al. [27] with one relaxation time and Kumar and Kansal [9]with two relaxation times. Laplace and Hankel transform techniques are used to obtain the expre...

despite wide-range of studies in the theories of the entrepreneurship field, few studies have offered a pervasive conceptual model or a general consensus of the existing theories. hence, this paper attempts to extend a comprehensive principle on entrepreneurship. in general, there are two common interpretations of the term ‘entrepreneurship’. one of the common views is schumpeterian, emphasizin...

In this short and deliberately provocative paper I reflect on what seems to be a yawning gulf between the potential contribution of the social sciences and the typically restricted models and concepts of social change embedded in contemporary environmental policy in the UK, and in other countries too. As well as making a strong case for going beyond what I refer to as the dominant paradigm of `...

Head and Noar (2013) wrote an interesting and challenging paper; we agree with many of their statements but disagree on a number of essential issues. We think that Head and Noar are (1) too negative about the current state of health behaviour theories, for example, the Reasoned Action Approach (RAA; Fishbein & Ajzen, 2010) and (2) too coercing with their recommendations. Head and Noar expect to...

A careful analysis of the definition of knowledge translation highlights the importance of the judicious translation of research into practice and policy. There is, however, a considerable gap between research and practice. Closing the research-to-practice gap involves changing clinical practice, a complex and challenging endeavor. There is increasing recognition that efforts to change practice...
