With a foreword by Thomas Sergiovanni, this book exposes the myths about school leadership which impede educational improvement. It also profiles 8 successful schools at which student achievement has flourished after collaboration was introduced.

Die Begriffe Recht, Unrecht, Verbrechen und Strafe werden in einem prinzipienorientierten Begründungszusammenhang entwickelt. Einem Kapitel über den Grundsatz der Gesetzlichkeit des Strafrechts folgen die Entfaltung des Begriffs der Straftat als tatbestandsmäßige, rechtswidrige, schuldhafte Handlung, das Tätigkeitsdelikt, das Unterlassungsdelikt, Rechtswidrigkeit und Rechtfertigungsgründe, die Schuld, der Versuch als Straftat, die Formen der Straftatbeteiligung. Den Abschluß bilden die Strafrechtsfolgen und das Strafmaß. Vom Prinzip des Rechts ausgehend ist das Werk speziell auf studentische Bedürfnisse didaktisch zugeschnitten und strikt gegliedert nach These, Begründungszusammenhang und Kritik sowie die Konkretisierung im geltenden Recht. Eine Bereicherung in der Lehrbuchlandschaft des Allgemeinen Teils.

Bei der Be­mes­sung wird die zu erwartende Be­an­spru­chung (Be­las­tung) mit der Be­an­spruch­bar­keit (Fes­tig­keit) verglichen, wo­bei die für den An­wen­dungs­fall not­wen­di­ge Si­cher­heit ge­währ­leis­tet wer­den muss.

Understanding the fatigue behaviour of structural components under variable load amplitude is an essential prerequisite for safe and reliable light-weight design.For designing and dimensioning, the expected stress (load) is compared with the capacity to withstand loads (fatigue strength). In this process, the safety necessary for each particular application must be ensured. A prerequisite for ensuring the required fatigue strength is a reliable load assumption.The authors describe the transformation of the stress- and load-time functions which have been measured under operational conditions to spectra or matrices with the application of counting methods. The aspects which must be considered for ensuring a reliable load assumption for designing and dimensioning are discussed in detail. Furthermore, the theoretical background for estimating the fatigue life of structural components is explained, and the procedures are discussed for numerous applications in practice. Oneof the prime intentions of the authors is to provide recommendations which can be implemented in practical applications.

In Alliances and Treaties between Frankish and Muslim Rulers Michael Köhler presents a fully integrated study of Frankish-Muslim diplomacy in the period from the First Crusade through to the thirteenth century. It is a ground-breaking study that challenges preconceived notions of the relations between Frankish and Muslim rulers in the Middle East. Commonly portrayed as an era of conflict, the period appears here as one in which conventions of diplomatic cooperation were commonplace. This book is one of the few works in the fields of Crusader Studies and Middle Eastern Studies that draws to the same extent on Arabic and Western sources; two textual traditions that have usually been studied in isolation from each other.

On the one hand, particle-based sensing techniques are driven by new technologies for preparing and measuring micro- and nanoparticles and by a fascination of the possibilities for design and functionalization of all specificities in structure shapes and behavior of these tiny objects. On the other hand, there evolves a fast-growing need for new sensing and communication paths for medicine, biotechnology, and analytical science, as well as for new and efficient information transfer and storage systems. No longer are particles regarded only as special types of materials. However, we have a better understanding of how they are bridging the gap between material and system, between structure and function. Although there are numerous books on micro- and nanoparticles and on sensors, there is, to the best of my knowledge, no book focusing on the general concept of particles as mobile microtransducers. This book clarifies that signal-transducing particles should be regarded as functional elements, as part of a system, not simply as special materials. It introduces concepts of bead-base sensing and "mobile spies" at the micro- and nanoscale and gives a representative overview of the variety of particle-based sensing. The state of the art in the development of particles as mobile spies for communication and information management allows us to speculate about future particle-based components and systems in a completely sustainable world economy. In addition, the book reports on a fast-evolving technical field, which is a typical example of the required convergence of technical strategies and mechanisms in living nature, and would make a great reference for professionals and students of chemistry, biochemistry, biology, pharmacy, medicine, agriculture, mechatronics, informatics, materials science, and systems engineering.

The conversion of the recent resource-wasting world economy to a sustainable economic system protecting global resources and habitats is crucial for the further development of humankind. This book introduces the physical basics and the importance of entropy for living beings, machines, computers, industrial facilities, ecological systems, and the earth as a whole. Readers of this book are encouraged to see the universal applicability of the entropy concept and the urgent need to estimate the fundamental importance of entropy for natural and technical processes. The key role of these processes has to be understood and recognized in order to coming to an intelligent adaptation on the arrow of time, which allows the conversion of all non-sustainable production processes into a global sustainable economy in a dynamical world.

Michael Köhler bestimmt das Prinzip des Rechts und die Gerechtigkeit als dessen Verwirklichung. Er erschließt die europäische Rechtsphilosophie und insbesondere die Leistung Kants, der von der Ethik guten Willens das Recht durch gesetzliche Selbstbestimmung im äußeren Verhältnis unterscheidet: Recht ist Form allgemeiner Freiheit in inhaltlicher Differenz. Kritik bezieht sich auf die Teleologik des älteren Naturrechts und auf den Empirismus, besonders den Utilitarismus, in der Gerechtigkeitstheorie auf Konzepte egalitärer Umverteilung wie die Wohlfahrtsökonomie, aber auch auf Rawls' widersprüchlichen Ansatz. Hingegen bieten freiheitsrechtliche Grundbegriffe wie das Menschenrecht, die Menschenpflichten, das Privatrecht, ursprünglicher Erwerb und der Vertrag die systematische Basis für die Hauptformen der Gerechtigkeit und deren Konkretisierung insbesondere in Familie und Gesellschaft. Im Gegenzug zur krisenhaften Gespaltenheit der Besitzverhältnisse bis hin zu den Extremen überflüssigen Reichtums und empörenden Elends wird vor allem die neu begründete Form der Teilhabegerechtigkeit herausgestellt. Diese räumt jeder Person aufgrund des ideal-ursprünglichen Gemeinbesitzes der Menschheit an der Weltsubstanz ein vermögensproportionales Erwerbsrecht ein - zu konkretisieren etwa in Rechten auf Bildung und auf Arbeit. Erst dadurch wird Gesellschaft ein ausgeglichenes Verhältnis freier, gleicher, selbständiger Bürger. Politisch entsprechen der Gerechtigkeitssystematik der demokratische, auf verantwortliche Repräsentation gegründete Rechtsstaat sowie ein Friedensbund souveräner (selbstbestimmter) Staaten, dessen Verfassung in weltbürgerlicher Hinsicht auch drängende Probleme internationaler Gerechtigkeit lösen könnte.
