product innovation success has very much to do with the development of models ormetaphors that are able to guide actors. one can observe two traditions in thisregard: rational and non-rational models. apparently in the former the model, suchas “development funnel”, is regarded as a mechanism and rigid applicable, picturinginnovation as an orderly, goal-oriented, value-neutral, and systematic pr...

Life science and biomedical technology start ups are a major focus for the establishment of innovation and knowledge-based economies. This article describes themes and practices in the monitoring of private company investments by life science-oriented venture capital firms and the possible relevance to this of project management concepts and techniques. A qualitative approach was adopted, using...

Many patients present debilitating symptoms related to myocardial ischemia which cannot be controlled by a rational combination of antianginal drugs due to uncontrolled progression of disease with arterial occlusion and diffuse involvement of previous grafts or postangioplasty restenosis, preventing new attempts of myocardial revascularization. This condition is defined as refractory angina, wh...

we characterize the rational subsets of a finite group and discuss the relations to integral cayley graphs.

While the limits of rational-calculative approaches for healthcare decision-making, alongside institutional forms ritual, routines and hope employed to deal with these limits, were already described in 1950s, professionals’ syncretism rational non-rational their everyday work remains a neglected topic Northern Europe. Using COVID-19 as an urgent problem policy practice, natural ‘breaching exper...

This study examined the association among interpersonal relationships, irrational beliefs, and life satisfaction. Twenty-eight psychotherapy clients and 207 college undergraduates completed measures of interpersonal relations (Outcome Questionnaire; Lambert et al., 1996), irrationality (Rational Behavior Inventory; Shorkey & Whiteman, 1977), and life satisfaction (The Satisfaction with Life Sca...

Because life annuities can increase the level and decrease the volatility of lifetime consumption, economists have long been puzzled by the low demand for life annuities. One potential rational explanation is that adverse selection drives up life annuity prices, which drives down demand. We study the choice between life annuities and lump sums made by 32,000 retiring public employees. These uni...

economists have heralded the formulation of the expected utility theorem as a universal method of choice under uncertainty. in their seminal paper, stigler and becker (stigler & becker, 1977) declared that “human behavior can be explained by a generalized calculus of utility-maximizing behavior” (p.76). the universality of the rational choice theory has been widely criticized by psychologists, ...

In this paper, we study a geometric G^2 Hermite interpolation by planar rational cubic Bézier curves. Two data points, two tangent vectors and two signed curvatures interpolated per each rational segment. We give the necessary and the sufficient intrinsic geometric conditions for two C^2 parametric curves to be connected with G2 continuity. Locally, the free parameters w...
