Book Description
A collection of scholarly essays, Complexity Theory and thePhilosophy of Education provides an accessible theoreticalintroduction to the topic of complexity theory while consideringits broader implications for educational change. Explains the contributions of complexity theory to philosophyof education, curriculum, and educational research Brings together new research by an international team ofcontributors Debates issues ranging from the culture of curriculum, to theimplications of work of key philosophers such as Foucault and JohnDewey for educational change Demonstrates how social scientists and social and educationpolicy makers are drawing on complexity theory to answer questionssuch as: why is it that education decision-makers are so resistantto change; how does change in education happen; and what does ittake to make these changes sustainable? Considers changes in use of complexity theory; developedprincipally in the fields of physics, biology, chemistry, andeconomics, and now being applied more broadly to the socialsciences and to the study of education

Flexoelectricity in Liquid Crystals

Book Description
The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.

Book Description
“Simplexity, as I understand it, is the range of solutions living organisms have found, despite the complexity of natural processes, to enable the brain to prepare an action and plan for the consequences of it. These solutions are simplifying principles that enable the processing of information or situations, by taking into account past experience and anticipating the future. They are neither caricatures, shortcuts, or summaries. They are new ways of asking questions, sometimes at the cost of occasional detours, in order to achieve faster, more elegant, more effective actions.” A. B. As Alain Berthoz demonstrates in this profoundly original book, simplicity is never easy; it requires suppressing, selecting, connecting, thinking, in order to then act in the best way possible. And what if we, in turn, are inspired by the living world to process the complexity that surrounds us? Alain Berthoz is professor at the Collège de France where he is co-director of the Laboratoire de physiologie de la perception et de l’action. [Laboratory for the physiology of perception and action]. He is a member of the French Academy of Sciences, and is the author of Le Sens du mouvement [The Brain's Sense of Movement] and La Décision [Emotion and Reason].

Book Description
It has been said that never has a monarch so narrowly missed "greatness" as did the Holy Roman Emperor Joseph II. An idealistic, sincere, and hardworking monarch whose ultilitarian bent, humanitarian instincts, and ambitious programs of reform in every area of public concern have prompted historians to term him an "enlightened despot," "revolutionary Emperor," "philosopher on a throne," and a ruler ahead of his time, Joseph has also been condemned for being insensitive to the phobias and follies of his subjects, essentially unrealistic, almost utopian, in establishing his goals, and dogmatic and overly precipitous in trying to achieve them. Efforts to analyze and explain the actions of this complex and controversial personality have involved a number of savants in investigations of "Josephinism" (or as I prefer to call it, "Josephism"), dealing in great detail with the motiva tions, substance, and influence of his innovations. The roots of Josephism run deep, but can be observed emerging here and there from the intellectual and political soil that nourished them, before joining the central trunk of the system formulated during the latter years of Maria Theresa's reign to grow to an ephemeral and stunted maturity under Joseph II.

Book Description
The design of mechanical structures with improved and predictable durability cannot be achieved without a thorough understanding of the mechanisms of fatigue damage and more specifically the relationships between the microstructure of materials and their fatigue properties. Written by leading experts in the field, this book (which is complementary to Fatigue of Materials and Structures: Application to Damage and Design, also edited by Claude Bathias and André Pineau), provides an authoritative, comprehensive and unified treatment of the mechanics and micromechanisms of fatigue in metals, polymers and composites. Each chapter is devoted to one of the major classes of materials or to different types of fatigue damage, thereby providing overall coverage of the field. The book deals with crack initiation, crack growth, low-cycle fatigue, gigacycle fatigue, shorts cracks, fatigue micromechanisms and the local approach to fatigue damage, corrosion fatigue, environmental effects and variable amplitude loadings, and will be an important and much used reference for students, practicing engineers and researchers studying fracture and fatigue in numerous areas of mechanical, structural, civil, design, nuclear, and aerospace engineering as well as materials science.

Book Description
In mechanical engineering and structural analysis there is a significant gap between the material models currently used by engineers for industry applications and those already available in research laboratories. This is especially apparent with the huge progress of computational possibilities and the corresponding dissemination of numerical tools in engineering practice, which essentially deliver linear solutions. Future improvements of design and life assessment methods necessarily involve non-linear solutions for inelastic responses, in plasticity or viscoplasticity, as well as damage and fracture analyses. The dissemination of knowledge can be improved by software developments, data base completion and generalization, but also by information and training. With such a perspective Non-Linear Mechanics of Materials proposes a knowledge actualization, in order to better understand and use recent material constitutive and damage modeling methods in the context of structural analysis or multiscale material microstructure computations.
