This volume presents a series of studies that expand laws, invariants, and principles of psychophysics beyond its classical domain of sensation. This book's goal is to demonstrate the extent of the domain of psychophysics, ranging from sensory processes, through sensory memory and short-term memory issues, to the interaction between sensation and action. The dynamics and timing of human performance are a further important issue within this extended framework of psychophysics: Given the similarity of the various cortical areas in terms of their neuroanatomical structure, it is an important question whether this similarity is paralleled by a similarity of processes. These issues are addressed by the contributions in the present volume using state-of-the-art research methods in behavioral research, psychophysiology, and mathematical modeling. The book is divided into four sections. Part I presents contributions concerning the classical domain of psychophysical judgment. The next two parts are concerned with elementary and higher-order processes and the concluding section deals with psychophysical models. The sections are introduced by guest editorials contributed by independent authors. These editorials present the authors' personals view on the respective section, providing an integrated account of the various contributions or highlighting their focus of interest among them. While also voicing their own and sometimes different point of view, they contribute to the process of discussion that makes science so exciting. This volume should be of great interest to advanced students in neuroscience, cognitive science, psychology, neuropsychology, and related areas who seek to evaluate the range and power of psychological work today. Established scientists in those fields will also appreciate the variety of issues addressed within the same methodological framework and their multiple interconnections and stimulating "cross-talk."

His discovery, however, marks the Corning, by blocking the neural con onset of the era of regional anaesthesia. It took almost one hundred years until his duction to the hind extremities of a dog by injecting cocaine-solution into the lumbar original idea of "local medication of the vertebral interspace, was the first to per cord" was again reconsidered due to two form spinal (or epidural?) anaesthesia [1]. reasons: At that time, he was unaware of the local I.

This handbook on human multitasking provides an integrative overview on simultaneous and sequential multitasking and thus combines theorizing on dual task limitations as well as costs related to task switching. In addition to a wide range of empirical findings and their theoretical integration, the editors provide a number of applications of multitasking, like training, interindividual differences and applied research in traffic and health psychology and music expertise. The book is suitable for people interested in multitasking, that is, for researchers and graduate students of cognitive psychology, movement science, sport psychology, cognitive neuroscience, cognitive and neurological rehabilitation, aging sciences, and broader cognitive science.

F}hrende Fachleute geben in Einzeldarstellungen Informationen zur Anwendung.Es wird einerseits auf die Probleme der weniger erfahrenen Portnutzer eingegangen, andererseits behandelt das Buch ausf}hrlich die gesamte Breite der heutigen Indikationen und zeigt die weitere Entwicklung auf.

Die industrielle Abfallwirtschaft ist Bestandteil der Produktions lehre mit volks- und betriebswirtschaftlicher BedeutuQg. okono misch betrachtet entsprechen Abfalle im Gegensatz zu Produkten nicht dem Sachziel der Unternehmung und mindern den Unternehmens erfolg . Abfalle konnen zugleich eine okologische Belastung dar stellen. Es gibt jedoch auch umweltunschadliche und okonomisch neutrale Guter, die aus Produktions- und Konsumtionsprozessen her vorgehen. Die vorliegende Arbeit beschaftigt sich aus betriebswirtschaftli cher sicht mit Abfallen, die in Kuppelprozessen bei der Herstel lung von sachzielgerechten Gutern entstehen; ausserdem werden Pro duktionsausschuss und nicht mehr produktiv nutzbare Guter wie Ver packungsstoffe, Altmaschinen und dergI. in die Betrachtungen ein bezogen. Ausgeklammert bleibt die Behandlung der hergestellten Produkte, die nach dem Verkauf eines Tages aus dem volkswirt schaftlichen Kreislauf ausscheiden und dann auch wieder zu Abfall in der Verantwortung des Herstellers werden konnen. Hauptanliegen des Verfassers sind neben der begrifflichen Klarung die systematische Darstellung der betrieblichen Handlungsmoglich keiten zur Abfallbewaltigung sowie die Weiterentwicklung von Me thoden der Planung und Kontrolle zur Unterstutzung der Entschei dungsfindung bei alternativen Wegen der Abfallbewaltigung. Bei den Massnahmen wird vorrangig die Abfallvermeidung untersucht, die hau fig untrennbar mit Ansatzen zur Rationalisierung verbunden ist und von daher im Zentrum betriebswirtschaftlicher Aktivitaten in der Unternehmenspraxis steht. Ausfuhrlich wird auch die wirtschaftli che Bedeutung staatlicher Massnahmen zur Erzwingung oder Forderung von Abfallbewaltigungsmassnahmen erortert."
