David Magnusson has been the most articulate spokesperson for a holistic, systems approach to personality. This paper considers three concepts relevant to a dynamic systems approach to personality: dynamics, systems, and levels. Some of the history of a dynamic view is traced, leading to an emphasis on the need for stressing the interplay among goals. Concepts such as multidetermination, equipotentiality, and equifinality are shown to be important aspects of a systems approach. Finally, attention is drawn to the question of levels of description, analysis, and explanation in a theory of personality. The importance of the issue is emphasized in relation to recent advances in our understanding of biological processes. Integrating such advances into a theory of personality while avoiding the danger of reductionism is a challenge for the future.

Global-Integration and Local-Responsiveness (IR) framework with four pairs of external environment and appropriate international strategy types has contributed significantly to international business management. Nevertheless, the framework is still incomplete and lacks dynamic features. To deal with such limitations and enhance the theory, this paper, therefore, brings dynamic features regarding both environment and strategy into the IR grid. Under a dynamic capability angle with three steps of sensing, seizing and transforming [30], the dynamic global integration and local responsiveness framework – a new concept building for international business – would be explicated.

ABSTRACT: We develop a model to show that transparent accounting can worsen the asset substitution effect of debt. This negative effect can outweigh the usual positive effect of transparency. We demonstrate this point by comparing pure historical cost accounting to the conservatively skewed accounting regime of lower-of-cost-or-market (LCM). In a market with asymmetric information, the two regimes lead to different degrees of transparency. The more transparent LCM regime produces more efficient results for firms with lower debt levels, while the opaque rule of pure historical cost accounting is preferable for higher debt levels. We explore the implications of this result for the firm's optimal capital structure.

Abstract Thrombin is the central protease of the coagulation cascade. Its activity is tightly regulated to ensure rapid blood clotting while preventing uncontrolled thrombosis. Thrombin interacts with multiple substrates and cofactors and is critically involved in both pro- and anticoagulant pathways of the coagulation network. Its allosteric regulation, especially by the monovalent cation Na+, has been the focus of research for more than 30 years. It is believed that thrombin can adopt an anticoagulant (‘slow’) conformation and, after Na+ binding, a structurally distinct procoagulant (‘fast’) state. In the past few years, however, the general view of allostery has evolved from one of rigid structural changes towards thermodynamic ensembles of conformational states. With this background, the view of the allosteric regulation of thrombin has also changed. The static view of the two-state model has been dismissed in favor of a more dynamic view of thrombin allostery. Herein, we review recent data that demonstrate that apo-thrombin is zymogen-like and exists as an ensemble of conformations. Furthermore, we describe how ligand binding to thrombin allosterically stabilizes conformations on the continuum from zymogen to protease.

In this work, the Winplot software was used to animate plane electromagnetic waves in a vacuum. The target audience was a class of 18 undergraduates in Physics and was applied at the Federal University of Acre, campus Rio Branco, in Brazil. The activity was carried out in a computer lab and conducted through a script with detailed instructions. The results were satisfactory, where participants got more than 60.0% right of four of the six investigative questions. In evaluating the activity, 88.9% considered it a good method to visualize the propagation of electromagnetic waves and 77.0% classified the activity as excellent or good. The application of the activity allowed a dynamic view of the propagation of plane electromagnetic waves in a vacuum, which could contribute to the teaching of such content.
