A classroom full of students can be overwhelming for teachers. It is critical that teachers are able to filter and meaningfully interpret the relevant information in this complex scenario. Much of this filtering and interpretation occurs through selective visual perception. Over the last decade, a rapidly growing number of studies in empirical educational research used eye tracking to investigate teachers' selective visual perceptual processes in the classroom. Theoretically, visual attention and perception are often conceptualized as knowledge-based noticing coupled with knowledge-based reasoning about what is visually perceived. Recent eye-tracking studies have shown that experienced teachers, in particular, show improved selective attention of classroom events through faster detection of relevant information and improved monitoring of learning-relevant situations. Researchers agree that a critical driver of selective attention processes is the professional knowledge (declarative, procedural, and metacognitive) of (experienced) teachers, which controls selective perceptual processes in a top-down process. The findings are significant and provide important insights for research on teacher professionalization.

Advancing Research on Teachers' Professional Vision: Implementing novel Technologies, Methods and Theories

Halder, Generalstabschef Hitlers, 1938-1942

Wehrmacht in der NS-Diktatur: Über 17 Millionen Soldaten. Kaum eine deutsche Familie, die nicht einen Angehörigen bei der Wehrmacht hatte. Was waren sie: Täter, Opfer, ganz "normale" Männer oder willige Vollstrecker? Um ihren Anteil an Krieg und Besatzung präzise und anschaulich zu bestimmen, konzentriert sich die Darstellung von Christian Hartmann auf fünf deutsche Divisionen. Sie hätten unterschiedlicher nicht sein können. Identisch sind dagegen ihr Einsatzraum, die Sowjetunion, und die Zeit, das erste Jahr des "Unternehmens Barbarossa". Gerade die Analyse dieses Mikrokosmos ́ bietet die Chance, einer Forderung zu entsprechen, die in der Debatte über die Wehrmacht oft zu hören war - die einer realistischen wie differenzierten Darstellung dieser Armee, ihrer Angehörigen und nicht zuletzt ihrer Funktionen, die sie in Hitlers Kriegen hatte.

Front und militärisches Hinterland 1941/42

Wehrmacht im Ostkrieg

The war between Nazi Germany and Stalin's Soviet Union that raged between 1941 and 1945 was unprecedented in the scale of the destruction that it wrought and the deep scars that it left behind. The invasion of the Soviet Union was the conflict that Hitler had always ultimately planned for in his dream of creating a 'Thousand Year Reich'. From the beginning it was a struggle for survival, conducted with great bitterness and savagery by opponents who knew that defeat meant the destruction of everything they stood for. By 1945 a huge swathe of Europe between Berlin and Moscow had been reduced to a devastated wasteland in which whole societies had been erased from the face of the earth. Over 26 million Soviets and between four and five million Germans lay dead. The eventual victory of the Red Army transformed the Soviet Union into one of the world's two superpowers. It also saw the complete destruction of Hitler's megalomaniac vision for the East, the division of the German Reich, and the Soviet domination of Eastern Europe for a generation. Enriched by a wealth of eye-witness testimony from both the Soviet and the German sides, Operation Barbarossa paints a masterly overview of these momentous four years and their human consequences - one that is both gripping and deeply moving.

With around 3 billion subscribers, GSM is the world's most commonly used technology for wireless communication. Providing an overview of the innovations that have fuelled this phenomena, GSM: Architecture, Protocols and Services, Third Edition offers a clear introduction to the field of cellular systems. Special emphasis is placed on system architecture and protocol aspects, and topics range from addressing concepts through mobility management to network management. This third edition contains around 25% new and reworked material and has been thoroughly updated to encompass recent advances and future trends. It serves as both an introductory textbook for graduate students as well as a reference resource for telecommunications engineers and researchers. This edition: Presents capacity enhancement methods like sectorization, the application of adaptive antennas for Spatial Filtering for Interference Reduction (SFIR) and Space Division Multiple Access (SDMA) Provides a detailed introduction to GPRS, HSCSD, and EDGE for packet-switched services and higher data rates Features updated coverage on the vastly expanded range of GSM services, including an examination of Multimedia Messaging Service (MMS) Adopts a highly graphical approach with numerous illustrations

GSM - Architecture, Protocols and Services

The war between Nazi Germany and Stalin's Soviet Union that raged between 1941 and 1945 was the ultimate confrontation between the two great totalitarian ideologies of the twentieth century. Unprecedented in the scale of the destruction that it wrought and the deep historical scars that it left behind, it was a gargantuan conflict in every sense of the term: in the vast territories over which it ranged, its intensity and duration, the huge numbers of people involved — and last but by no means least, the millions of victims that it claimed. The invasion of the Soviet Union was the conflict that Hitler had always ultimately planned for: a pitiless war of conquest and destruction in which the Fuehrer dreamed of creating his 'Thousand Year Reich', destroying his ideological opponents, and enslaving or 'eliminating' whole peoples in the process. It was right from the start a struggle for survival, conducted with great bitterness and savagery by opponents who knew that defeat meant the destruction of everything they stood for. The outcome of this bitter struggle was quite as momentous as the struggle which had preceded it. By 1945 a huge swathe of Europe between Berlin and Moscow had been reduced to a devastated wasteland in which whole societies had been erased from the face of the earth. Over 26 million Soviets and between four and five million Germans lay dead. The victory of the Red Army transformed the Soviet Union into one of the world's two superpowers. It also saw the complete destruction of Hitler's megalomaniac vision for the East, the division of the German Reich, and the Soviet domination of Eastern Europe for a generation. In Operation Barbarossa, German military historian Christian Hartmann draws upon the latest research, enriched by a wealth of eye-witness testimony from both the Soviet and the German sides, to paint a masterly overview of these momentous four years and their human consequences - one that is both gripping, and at times deeply moving.

Die Kongre b{nde der Deutschsprachigen Gesellschaft f}r Intraokularlinsen Implantation haben sich in den letzten Jahren als die umfassendste und auch am meisten zitierte Quelle von Arbeiten zur Katarakt- und refraktiven Hornhautchirurgie erwiesen. Auch der nun vorliegende Band, der die anl{ lich des 6. Kongresses der Gesellschaft im M{rz 1992 vorgetragenen Arbeiten enth{lt, bringt f}r Ophthalmologen eine F}lle von Informationen. Der Leser erh{lt einen gut gegliederten ]berblick }ber Themen wie etwa Linsenoperationen, alternative Linsen- fixation, refraktive und allgemeine Hornhautchirurgie, Astigmatismus, Pharmakologie - um nur einige zu nennen.

Zur Kapazitätserhöhung in zellularen Mobilfunksystemen eignet sich der Einsatz adaptiver Antennen an der Basisstation. Diese ermöglichen die räumliche Wiederverwendung von Kanälen innerhalb einer Zelle mittels Space Division Multiple Access (SDMA). Die Kapazitätsgewinne, die mit SDMA zu erzielen sind, hängen jedoch stark von den verwendeten Verfahren des Ressourcen Managements (RM) ab. Hierzu wurden neuartige RM-Verfahren für SDMA-Systeme entwickelt, welche die räumliche Kanalwiederverwendung innerhalb der Zelle mit verschiedenen Prinzipien der interzellularen Kanalvergabe (statische und dynamische) kombinieren. Zudem wurden die entwickelten Verfahren erweitert, um auch in hierarchisch strukturierten zellularen Netzen eingesetzt werden zu können. In ausführlichen Systemsimulationen konnte gezeigt werden, dass die neuen RM-Verfahren eine Vervielfachung der Systemkapazität mit Hilfe von SDMA ermöglichen. Zusätzlich werden analytische Modelle entwickelt und ausgewertet, die den Gewinn von Verfahren vorhersagen, welche die durch die Verwendung adaptiver Antennen reduzierte Inter-Zell-Interferenz ausnutzen (Spatial Filtering for Interference Reduction-SFIR), dies wird sowohl für F/TDMA basierte Systeme als auch für CDMA Systeme analysiert.
