a SPECIAL ISSUE II, pp. 20 – 33, 2008 PHENOMENOLOGY, NEUROSCIENCE AND IMPAIRMENT
The discovery of strong γ–ray and hard X–ray emission and the results from various multifrequency campaigns have disclosed new aspects of the blazar phenomenology, leading to a much more robust understanding of the mechanisms underlying their emission, and offering clues for the energetics of their relativistic jets. I review these aspects, and propose that all the diversity in the blazar pheno...
A phenomenological model for species spreading which incorporates the Allee effect, a species’ maximum attainable growth rate, collective dispersal rate and dispersal adaptability is presented. This builds on a well-established reaction-diffusion model for spatial spreading of invading organisms. The model is phrased in terms of the “hostility” (which quantifies the Allee threshold in relation ...
We discuss the experimental evidence supporting the concept of universality of the rapidity gap probability in soft and hard diffraction, relate the gap probability to hadronic parton densities, and present a phenomenological model of diffraction in which the structure of the Pomeron is derived from the structure of the parent hadron. Predictions for diffractive deep inelastic scattering are co...
In this article, I first propose to reinterpret R. T. Craig’s (1999) call for a dialogue between communication perspectives as a formulation of design specs to which any constitutive model of communication should respond. I then propose to answer this call by metaphorically conceiving of communication as a form of ventriloquism, which translates our capacity to make other beings say or do thing...
We show that the dynamical contraction of n "internal" spacelike dimensions leads, in general, to the formation of a cosmic graviton background, similar to that produced by innation. By using a simple phenomenological model we discuss how to obtain information and constraints on the total number of extra dimensions, on their compactiication scale and on the kinematics of the dimensional reducti...
The ansatz of vanishing A and B parameters eliminates CP violating complex phases in soft supersymmetry-breaking parameters of the minimal supersymmetric standard model, and thus provides a simple solution to the supersymmetry CP problem. Phenomenological implications of this ansatz are investigated in the framework of minimal supergravity. We show that electroweak symmetry breakdown occurs, pr...
Abstract Introduction: Emotional stress due to futile care is very high and decreasing level of futile care can result in decrease of stress and increase nurses’ job satisfaction. Objective: This study aimed to determine intensive care nurses’ reaction to futile cares. Methods: In this qualitative study, a phenomenological approach was used. This study was conducted to un...
Money as a tool has all the dimensions of life. The meaning of money has been expanded so that its social dimensions can be used alone to analyze the economic situation and market of a society. In this study, we examine the semantic dimensions and meaning that students have of money. The research method is phenomenological research. Deep interviews were conducted of 21 sample students from Ferd...
Introduction: The issue of care is an integral part of accidents and crises and the design of effective models and methods in its management, especially the methods that have emerged from the context is very important. Objective: Nursing management in crises due to the importance of its role has always been one of the topics of interest. Therefore, the present study was conducted to explain the...
