Since its inception in the famous 1936 paper by Birkhoff and von Neumann entitled "The logic of quantum mechanics quantum logic, i.e. the logical investigation of quantum mechanics, has undergone an enormous development. Various schools of thought and approaches have emerged and there are a variety of technical results.Quantum logic is a heterogeneous field of research ranging from investigations which may be termed logical in the traditional sense to studies focusing on structures which are on the border between algebra and logic. For the latter structures the term quantum structures is appropriate. The chapters of this Handbook, which are authored by the most eminent scholars in the field, constitute a comprehensive presentation of the main schools, approaches and results in the field of quantum logic and quantum structures. Much of the material presented is of recent origin representing the frontier of the subject. The present volume focuses on quantum structures. Among the structures studied extensively in this volume are, just to name a few, Hilbert lattices, D-posets, effect algebras MV algebras, partially ordered Abelian groups and those structures underlying quantum probability.- Written by eminent scholars in the field of logic- A comprehensive presentation of the theory, approaches and results in the field of quantum logic- Volume focuses on quantum structures

Quantum mechanics is said to be the most successful physical theory ever. It is, in fact, unique in its success when applied to concrete physical problems. On the other hand, however, it raises profound conceptual problems that are equally unprecedented. Quantum logic, the topic of this volume, can be described as an attempt to cast light on the puzzle of quantum mechanics from the point of view of logic. Since its inception in the famous 1936 paper by Birkhoff and von Neumann entitled, "The logic of quantum mechanics, quantum logic has undergone an enormous development. Various schools of thought and approaches have emerged, and there are a variety of technical results. The chapters of this volume constitute a comprehensive presentation of the main schools, approaches and results in the field of quantum logic.- Authored by eminent scholars in the field- Material presented is of recent origin representing the frontier of the subject- Provides the most comprehensive and varied discussion of Quantum Mechanics available

Seminar paper from the year 2006 in the subject Business economics - Offline Marketing and Online Marketing, grade: 1,7, LMU Munich, language: English, abstract: This paper investigates the evaluation of the measurement properties of collage research. After a classification and an introduction about the qualitative and visual research, the collage technique is described. Different characteristics and aspects of a collage are shown. Then, the classical measurement properties are explained in detail: Objectivity, reliability and validity. A conclusion is always pointed out of the results for the collage research. All in all, the classical measurement properties cannot be adapted simply to the collage technique. Finally, the most important issues are resumed and an outlook for further researches is taken. The analysis is focused on expert literature like market research papers and different textbooks. The difficulty was to develop guidelines for the collage research based on the classical measurement properties. Besides, a discussion with a researcher enforced the results in a qualitative way. Finally the soundness of the findings is guaranteed due to the continuous review of the sources and the data.

Daniel, Lehrer in Baden-Württemberg und Julius, Historiker in Berlin, verbindet eine gescheiterte Liebesbeziehung. Vor dem Hintergrund der Corona-Krise treffen Sie erneut aufeinander, und stellen im Laufe des Romans fest, dass auch die Geschichten ihrer Familien weitaus enger miteinander verknüpft sind, als sie ahnten. Ost-Biographie trifft auf West-Biographie im 30 Jahre wiedervereinten Deutschland.Vor dem Hintergrund der Corona-Krise entwickeln sich um die beiden Protagonisten Daniel und Julius verschiedene Erzählstränge. Der etwas über 40jährige Daniel wünscht sich einen festen Partner und möchte ein Kind aus Bulgarien adoptieren. Sein Ex Julius steht vor den Scherben seiner prekären Existenz: keine Beziehung, Wohnung wegen Eigenbedarf gekündigt, das Einkommen bricht weg.Daniel unternimmt mit seinen Schülern eine Klassenfahrt in die alte Heimat Berlin. Beim Besuch des ehemaligen Stasi-Gefängnisses Hohenschönhausen sorgt er für ein Wiedersehen mit Julius. Dieser arbeitet hier, wo seine Großeltern und sein Vater einst inhaftiert waren. Seine sicher geglaubte Teilzeit-Anstellung scheitert in letzter Sekunde aufgrund der Ungewissheit der Corona-Krise. Er wird nicht nur diesen Job verlieren, auch seine Tätigkeit als Deutschlehrer eines Integrationskurses für Flüchtlinge wird ausgesetzt.In der Ausnahmesituation der Krise treffen Daniel und Julius in Rügen erneut aufeinander:Daniel muss sich um seinen Vater kümmern, dessen polnische Pflegerin nicht mehr einreisen kann. Julius nutzt den Shutdown sich endlich mit dem Haus seines verstorbenen Vaters auseinanderzusetzen. Aus Stasi-Unterlagen weiß er, dass seine Eltern mit ihrem Segelboot Fluchthelfer in den Westen waren. Bei einem Fluchtversuch kam seine Mutter ums Leben. Während des Aufenthaltes auf der Insel kommt die Wahrheit über die schicksalshafte Flucht ans Licht.Eingewoben und mit der Hauptgeschichte verbunden sind zwei weitere Fluchtschicksale: Die Geschichte eines jüdischen Mannes, der 1938 auf der St. Louis über den Atlantik flüchtet, und die Flucht einer syrischen Frau über das Schwarze Meer nach Bulgarien.
