abstract: new approaches to strategy have accepted strategic thinking as a complement or even an alternative for strategic planning. indeed, strategic thinking capability has been recognized as a characteristic of successful top managers in organizations. moreover, the extant literature emphasizes the fact that top level managers can be taught to think strategically. however, there is no compre...

Surfactant secretion must be regulated to maintain a low surface tension in the lung during various conditions such as exercise. In vitro studies reveal a slow, unique exocytotic process at the interface of stimulated and constitutive exocytosis. The exocytotic mechanisms and sites of regulation in vivo, however, are still poorly understood.

The forced vibration behaviors are examined for nonlocal strain gradient nanobeams with surface effects subjected to a moving harmonic load travelling with a constant velocity in terms of three beam models namely, the Euler-Bernoulli, Timoshenko and modified Timoshenko beam models. The modification for nonlocal strain gradient Timoshenko nanobeams is exerted to the constitutive equations by exc...

Semi-solid materials undergo strain localization and shear band formation as a result of granular nature of semi-solid deformation. In the present study, to analyze the shear localization, a unified viscoplastic constitutive model was developed for the homogeneous flow. Then, a linearized analysis of the stability performed by examining the necessary condition for the perturbation growth. For t...

John Searle’s theory of social ontology posits that there are indispensable normative components in the linguistic apparatuses termed status functions, collective intentionality, and collective recognition, all of which, he argues, make the social world. In this paper, I argue that these building blocks of Searle’s social ontology are caught in a petitio of constitutive circularity. Mo...

The aim of this article is to show, how computer algebra can be used when applying Liu’s procedure. Although I will use Mathematica (a commercial product by Wolfram Research) it is possible to use other computer algebra systems as well. This was the reason for me to choose LTEX for this article and not just to publish my mathematica-notebook. 1 Thermodynamics: Liu’s Procedure (A very short intr...

We have examined the constitutive and inducible secretion of platelet-derived growth factor (PDGF)-like proteins in a variety of human hemopoietic cell lines. The highest levels of secreted protein were noted in four human erythroleukemia lines which, in addition to erythroid lineage markers, express one or more megakaryocytic lineage markers. Induction of these lines by 12O-tetradecanoylphorbo...

This review article is concerned with the mathematical modelling of the mechanical properties of the soft biological tissues that constitute the walls of arteries. Many important aspects of the mechanical behaviour of arterial tissue can be treated on the basis of elasticity theory, and the focus of the article is therefore on the constitutive modelling of the anisotropic and highly nonlinear e...
