Der Mann, Versorger und Oberhaupt der Familie? Das klassische Rollenbild ist überholt. Doch was ist die Alternative? Viele Männer suchen Orientierung. Dirk Schröder, der "Männer-Coach", hilft ihnen, ihre Berufung in der Familie, im Beruf und in der Gesellschaft zu finden und neue Perspektiven zu entwickeln. Seine Spezialität: "Sail & Coach", ein siebentägiger Segeltörn mit zehn Männern auf einer Yacht im Mittelmeer. In seinem Buch nimmt Dirk Schröder den Leser mit auf einen solchen Törn. Er erzählt von den Erlebnissen der Teilnehmer und gibt Lösungsansätze zu den dringensten Fragen. Dabei geht er auf wichtige Themen wie Selbstbild, Motivation, Träume und Ziele ein – jeweils mit Tipps zur praktischen Umsetzung. Hier finden Männer die ersehnte Orientierung und Ermutigung.

Mit dem Männer-Coach auf klarem Kurs

Voll im Wind – voll im Leben

Analogous to visualization, the auralization of virtual environments describes the simulation of sound propagation inside enclosures where methods of Geometrical Acoustics are mostly applied for a high-quality synthesis of aural stimuli that go along with a certain realistic behavior. In the course of this thesis, the design and implementation of the real-time room acoustics simulation software RAVEN will be described, which is a vital part of the implemented 3D sound-rendering system of RWTH Aachen University's immersive Virtual Reality system. RAVEN relies on present-day knowledge of room acoustical simulation techniques and enables a physically accurate auralization of sound propagation in complex environments including important wave effects such as sound scattering, airborne sound insulation between rooms and sound diffraction. Despite this realistic sound field rendering, not only spatially distributed and freely movable sound sources and receivers are supported at runtime but also modifications and manipulations of the environment itself. All major features are evaluated by investigating both the overall accuracy of the room acoustics simulation and the performance of implemented algorithms, and possibilities for further simulation optimizations are identified by assessing empirical studies of subjects operating in immersive environments

In recent years, the idea of a concept has become increasingly central to different areas of philosophy. This collection of original essays presents philosophical perspectives on the link between concepts and language, concepts and experience, concepts and know-how, and concepts and emotion. The essays span a variety of interrelated philosophical domains ranging from epistemology, philosophy of language, philosophy of mind, philosophy of action, and the philosophy of emotions. Among the central questions addressed by the contributors are: What are concepts? What is nonconceptual content? Does perceptual experience have conceptual content? Is conceptual thought language dependent? How do we form new concepts? Does practical knowledge have propositional content? Is practical understanding conceptual (without being propositional)? Do emotions have a representational content and if so, is the representational content conceptual? Concepts in Thought, Action, and Emotion advances current debates about concepts and will interest scholars across a broad range of philosophical disciplines.
