Vermittlung und Erwerb von Mathematischer Modellierungskompetenz: Zur Förderung eines ganzheitlichen Bildes der Mathematik im Schulunterricht (essentials)
by Alexander BrödnerDieses Buch bietet eine grundlegende Einführung in die wichtigsten Aspekte der Vermittlung und des Erwerbs von mathematischer Modellierungskompetenz im Schulkontext. In den letzten Jahren hat sich unter anderem anhand der Covid-19 Pandemie mehr denn je gezeigt, wie Mathematik im Allgemeinen und das mathematische Modellieren im Speziellen zum Verständnis globaler Herausforderungen und Möglichkeiten zu ihrer Bewältigung beiträgt. Deshalb sollte die mathematische Modellierungskompetenz eine zentrale Rolle im Schulunterricht spielen. Dies kann auch zur Vermittlung eines ganzheitlichen Bildes der Mathematik beitragen. Doch der Prozess von Vermittlung und Erwerb einer solchen Kompetenz ist komplex und mit vielfältigen Schwierigkeiten verbunden. Angesichts dieser Ausgangslage fasst das Buch Geschichte und Definition der Modellierungskompetenz im Mathematikunterricht zusammen, stellt die damit verbundenen Ziele und Perspektiven dar, veranschaulicht theoretische Hintergrundüberlegungen, stellt Modellierungsaufgaben und passende Lernumgebungen vor und weist auf notwendige Teilkompetenzen und mögliche Hindernisse beim Erwerb von Modellierungskompetenz hin. Letztendlich wird damit auch der Anspruch der Vermittlung eines ganzheitlichen Bildes der Mathematik im Schulunterricht angesprochen. Als Zusammenfassung der wichtigsten Aspekte des mathematischen Modellierungskompetenz im Schulkontext richtet sich das Buch an Mathematikdidaktiker*innen und Lehrkräfte aller Schulformen.

Vertex-Frequency Analysis of Graph Signals (Signals and Communication Technology)
by Ljubiša Stanković Ervin SejdićThis book introduces new methods to analyze vertex-varying graph signals. In many real-world scenarios, the data sensing domain is not a regular grid, but a more complex network that consists of sensing points (vertices) and edges (relating the sensing points). Furthermore, sensing geometry or signal properties define the relation among sensed signal points. Even for the data sensed in the well-defined time or space domain, the introduction of new relationships among the sensing points may produce new insights in the analysis and result in more advanced data processing techniques. The data domain, in these cases and discussed in this book, is defined by a graph. Graphs exploit the fundamental relations among the data points. Processing of signals whose sensing domains are defined by graphs resulted in graph data processing as an emerging field in signal processing.Although signal processing techniques for the analysis of time-varying signals are well established, the corresponding graph signal processing equivalent approaches are still in their infancy. This book presents novel approaches to analyze vertex-varying graph signals. The vertex-frequency analysis methods use the Laplacian or adjacency matrix to establish connections between vertex and spectral (frequency) domain in order to analyze local signal behavior where edge connections are used for graph signal localization. The book applies combined concepts from time-frequency and wavelet analyses of classical signal processing to the analysis of graph signals. Covering analytical tools for vertex-varying applications, this book is of interest to researchers and practitioners in engineering, science, neuroscience, genome processing, just to name a few. It is also a valuable resource for postgraduate students and researchers looking to expand their knowledge of the vertex-frequency analysis theory and its applications. The book consists of 15 chapters contributed by 41 leading researches in the field.
Vertrauen in die Polizei: Schweiz – Europa – Welt
by Sabrina PfisterDas vorliegende Buch befasst sich mit Vertrauen in die Polizei, wobei die Makroebene wie auch die Individualebene betrachtet und miteinander verknüpft werden. Auf der Makroebene fokussiert die Autorin die wahrgenommene Korruption, auf der Individualebene individuelle Werte sowie Migrationshintergründe als Erklärungsfaktoren. Insbesondere der Einfluss von Werten auf Vertrauen in die Polizei wurde bisher kaum untersucht. In dieser Analyse werden anhand einer Fallstudie über die Schweiz wie anhand welt- und europaweiter Ländervergleiche die Faktoren sowohl auf der Individual- als auch auf der Länderebene analysiert und folgende Forschungsfrage empirisch bearbeitet: Wie lassen sich Vertrauensunterschiede in die Polizei zwischen Menschen in einem Land und zwischen Ländern erklären? Es zeigt sich, dass öffentliche Korruption (gemessen mit dem Corruption Perceptions Index), die vier individuellen Werte «Bewahrung», «Macht», «Selbstbestimmung» und «Universalismus» nach der Wertetheorie von S. H. Schwartz (1992) und ein allenfalls vorhandener Migrationshintergrund Unterschiede im Vertrauen in die Polizei erklären können.

Very First Steps in Random Walks: The Power of Combinatorial Methods and Generating Functions (Mathematics Study Resources #17)
by Norbert HenzeWith this book, which is based on the third edition of a book first written in German about random walks, the author succeeds in a remarkably playful manner in captivating the reader with numerous surprising random phenomena and non-standard limit theorems related to simple random walks and related topics. The work stands out with its consistently problem-oriented, lively presentation, which is further enhanced by 100 illustrative images. The text includes 53 self-assessment questions, with answers provided at the end of each chapter. Additionally, 74 exercises with solutions assist in understanding the material deeply. The text frequently engages in concrete model-building, and the resulting findings are thoroughly discussed and interconnected. Students who have tested this work in introductory seminars on stochastics were particularly fascinated by the interplay of geometric arguments (reflection principle), combinatorics, elementary stochastics, and analysis. This book is a translation of an original German edition. The translation was done with the help of artificial intelligence. A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation.
The Vexing Case of Igor Shafarevich, a Russian Political Thinker
by Krista BerglundThis is the first comprehensive study about the non-mathematical writings and activities of the Russian algebraic geometer and number theorist Igor Shafarevich (b. 1923). In the 1970s Shafarevich was a prominent member of the dissidents' human rights movement and a noted author of clandestine anti-communist literature in the Soviet Union. Shafarevich's public image suffered a terrible blow around 1989 when he was decried as a dangerous ideologue of anti-Semitism due to his newly-surfaced old manuscript Russophobia. The scandal culminated when the President of the National Academy of Sciences of the United States suggested that Shafarevich, an honorary member, resign. The present study establishes that the allegations about anti-Semitism in Shafarevich's texts were unfounded and that Shafarevich's terrible reputation was cemented on a false basis.
Viability and Resilience of Complex Systems
by Nigel Gilbert Guillaume DeffuantOne common characteristics of a complex system is its ability to withstand major disturbances and the capacity to rebuild itself. Understanding how such systems demonstrate resilience by absorbing or recovering from major external perturbations requires both quantitative foundations and a multidisciplinary view on the topic. This book demonstrates how new methods can be used to identify the actions favouring the recovery from perturbations. Examples discussed include bacterial biofilms resisting detachment, grassland savannahs recovering from fire, the dynamics of language competition and Internet social networking sites overcoming vandalism. The reader is taken through an introduction to the idea of resilience and viability and shown the mathematical basis of the techniques used to analyse systems. The idea of individual or agent-based modelling of complex systems is introduced and related to analytically tractable approximations of such models. A set of case studies illustrates the use of the techniques in real applications, and the final section describes how one can use new and elaborate software tools for carrying out the necessary calculations. The book is intended for a general scientific audience of readers from the natural and social sciences, yet requires some mathematics to gain a full understanding of the more theoretical chapters. It is an essential point of reference for those interested in the practical application of the concepts of resilience and viability

Videobasierte Kompetenzmessung in der universitären Lehrkräfteausbildung: Evidenz aus Literaturreviews und empirischen Untersuchungen (Perspektiven der Mathematikdidaktik)
by Jonas WeyersInnerhalb der Forschung zur professionellen Kompetenz von Lehrkräften kommen vermehrt videobasierte Kompetenzmessungen zum Einsatz. Durch die Kombination von Videomaterial unterrichtlicher Praxis mit spezifischen Testfragen sollen Rückschlüsse auf handlungsnahe Kompetenzen bzw. sogenannte situationsspezifische Fähigkeiten von Lehrkräften ermöglicht werden. Auf Basis von zwei Literaturreviews untersucht die vorliegende Arbeit die Konzeption und Erfassung situationsspezifischer Fähigkeiten am Beispiel des Konstrukts "Teacher Noticing", welches in der mathematikdidaktischen Forschung besonders verbreitet ist, und gibt einen umfassenden Überblick zu vorliegenden Testinstrumenten, die auf dieses Konstrukt abzielen. Insbesondere wird diskutiert, inwieweit unterschiedliche Messansätze zu vergleichbaren Ergebnissen führen und welche Konsequenzen sich aus der Heterogenität der Messansätze für den wissenschaftlichen Diskurs ergeben. Anhand zweier empirischer Arbeiten wird weiterführend geprüft, inwieweit anspruchsvolle videobasierte Kompetenzmessungen bereits mit Lehramtsstudierenden einsetzbar sind und Rückschlüsse auf deren Kompetenzentwicklung zulassen. Die Ergebnisse stützen dabei grundsätzlich die Einsetzbarkeit in der universitären Phase der Lehrkräfteausbildung, wobei sich nur geringe Zusammenhänge zu den Lerngelegenheiten innerhalb dieses Ausbildungsabschnitts zeigen.
