Fuzzy Surfaces in GIS and Geographical Analysis: Theory, Analytical Methods, Algorithms and Applications
by Weldon LodwickSurfaces are a central to geographical analysis. Their generation and manipulation are a key component of geographical information systems (GISs). However, geographical surface data is often not precise. When surfaces are used to model geographical entities, the data inherently contains uncertainty in terms of both position and attribute. Fuzzy

Förderung der Entwicklung im mittleren und höheren Lebensalter: Eine Perspektive der positiven Psychologie
by Irina Catrinel CrăciunDieses Handbuch integriert und erörtert eine wachsende Evidenzbasis zur individuellen Entwicklung im mittleren und späten Erwachsenenalter. Das Buch enthält eine umfassende Analyse dessen, was Wachstum in der Lebensmitte und im höheren Alter bedeutet, und zeigt auf, wie verschiedene Entwicklungsbereiche miteinander verwoben sind (d. h. körperliche, kognitive, soziale und emotionale Entwicklung sowie Persönlichkeitsentwicklung). Da die Kluft zwischen Theorie und Praxis immer noch ein Problem in der Entwicklungsforschung darstellt, zielt das Handbuch auch darauf ab, anschauliche Beispiele für Prävention und Intervention aus der Perspektive der positiven Psychologie zu liefern. Diese wurden so ausgewählt, dass sie eine Vielzahl von Themen repräsentieren, die für die individuelle Entwicklung relevant sind und bei denen die Forschung die Praxis beeinflusst, von Glück, Großelternschaft, Liebe und Sexualität bis hin zu Einsamkeit, Depression, Angst, Suizidprävention und Bewältigung des Todes.Dieses Handbuch ist ein unverzichtbares Hilfsmittel für Studenten und Forscher, die in den Bereichen Entwicklungspsychologie, Gesundheitspsychologie, Gerontologie und öffentliche Gesundheit arbeiten. Es ist auch für Praktiker wie Berater, Life Coaches, Psychotherapeuten, Organisationspsychologen, Gesundheitsfachleute, Sozialarbeiter und Planer im Bereich der öffentlichen Gesundheit von Interesse.
Förderung der Motivation im Mathematikunterricht des Berufskollegs: Konzeption und Evaluation eines motivierenden Lehr-Lern-Arrangements (Studien zur theoretischen und empirischen Forschung in der Mathematikdidaktik)
by Julia Elena KillingDie vorliegende Arbeit stellt die Konzeption und Evaluation von zwei Lehr-Lern-Arrangements zum Themengebiet der Stochastik am Berufskolleg dar. Die Evaluation der beiden Lehr-Lern-Arrangements erfolgt durch die Auswertung der Wirkung auf die Motivation der Lernenden in einer quantitativ quasi-experimentellen Interventionsstudie im Prä-Post-Design. Zur Auswertung wurde die Motivation vor und nach den Lehr-Lern-Arrangements sowie die Leistungsfähigkeit zu Beginn des Lehr-Lern-Arrangements der N = 195 teilnehmenden Lernenden aus fünf Berufskollegs erhoben und kumulativ ausgewertet. Die Auswertung zeigt, dass sich die Motivation der Lernenden lediglich im betrieblichen Lehr-Lern-Arrangement signifikant verbessern ließ. Im anwendenden Lehr-Lern-Arrangement und in der Kontrollgruppe ließen sich keine signifikanten Veränderungen der Motivation feststellen. Ebenfalls ließ sich kein Zusammenhang zwischen der Wirkung der Lehr-Lern-Arrangements auf die Motivation und der vorherigen Leistungsfähigkeit der Lernenden feststellen. Daher lässt sich insgesamt schlussfolgern, dass betriebliche Lehr-Lern-Arrangements einen positiven Einfluss auf die Motivation von Lernenden am Berufskolleg haben.
Förderung der Zahlbegriffsentwicklung bei sehenden und blinden Kindern
by Juliane LeudersDie wissenschaftliche Kenntnislage zur Entwicklung mathematischer Kompetenzen bei blinden Kindern ist lückenhaft, heterogen und teilweise widersprüchlich. Auch für sehende Kinder wurden psychologische Forschungsergebnisse bisher nur teilweise aus didaktischer Perspektive ausgewertet. Juliane Leuders bietet einen umfassenden Überblick über den deutschen und englischsprachigen Forschungsstand zu den Grundlagen des Arithmetiklernens von sehenden und blinden Vorschulkindern und Schulanfängern. Sie thematisiert neuro- und wahrnehmungspsychologische Grundlagen des Hörens und Tastens und erörtert kognitive Prozesse und die Entwicklung des zahlbezogenen Denkens. Im didaktischen Teil beschreibt sie den Kompetenzerwerb im inklusiven Unterricht, die Qualität von Veranschaulichungen und erarbeitet konkrete Vorschläge für die Adaption von Unterrichtsmaterialien.
Förderung diagnostischer Kompetenz angehender Grundschullehrkräfte (Mathematikdidaktik im Fokus)
by Jan Philipp VolkmerDiagnostische Kompetenz ist eine der zentralen Kompetenzen von Lehrkräften. Diese Kompetenz hängt von der jeweiligen diagnostischen Situation ab. Das Analysieren von reichhaltigen Schüler*innendokumenten, wie sie zum Beispiel bei der Bearbeitung offener Lernangebote entstehen, wurde als diagnostische Situation bisher kaum betrachtet. Das vorliegende Buch widmet sich daher der Operationalisierung und Förderung diagnostischer Kompetenz bezüglich der Analyse von Schüler*innendokumenten zu offenen Lernangeboten der Arithmetik. Dazu wird eine Operationalisierung der diagnostischen Kompetenz und insbesondere des diagnostichen Denkens als Synthese bisheriger Forschung vorgeschlagen. Die Operationalisierung stützt sich auf die Adaption epistemischer Aktivitäten und einen adaptierten Prozess des Anpassens und Vergleichens. Weiter werden zwei empirische Studien vorgestellt, die die Wirksamkeit verschiedener Interventionen zur Förderung diagnostischer Kompetenz nachweisen können.
Förderung von diagnostischen Kompetenzen: Eine empirische Untersuchung mit Mathematik-Lehramtsstudierenden (Mathematikdidaktik im Fokus)
by Natalie HockIn der vorliegenden Studie wurde empirisch nachgewiesen, dass eine gezielte Intervention dazu beitragen kann, die Fehler-Ursachen-Diagnosekompetenz von Mathematik-Lehramtsstudierenden zu fördern. Diese spezifische Diagnosekompetenz ist notwendig, um Schülerfehler und deren Ursachen zu diagnostizieren, denn die abschließende Diagnose bildet die Grundlage für eine Differenzierung im Unterricht sowie diverse Förderangebote. Auch in der aktuellen Bildungspolitik erhalten diese Aspekte eine immer stärkere Beachtung aufgrund der zunehmenden Heterogenität der Schülerschaft.
G Families of Probability Distributions: Theory and Practices
by Mohamed Ibrahim Mir Masoom Ali Irfan Ali Haitham M. YousofStatistical distributions are essential tools to model the characteristics of datasets, such as right or left skewness, bi-modality or multi-modality observed in different applied sciences, such as engineering, medicine, and finance. The well-known distributions like normal, Weibull, gamma and Lindley are extensively used because of their simple forms and identifiability properties. In the last decade, researchers have focused on the more complex and flexible distributions, referred to as Generalized or simply G families of probability distributions, to increase the modelling capability of these distributions by adding one or more shape parameters.The main aim of this edited book is to present new contributions by researchers in the field of G families of probability distributions. The book will help researchers to: Develop new univariate continuous and discrete G families of probability distributions. Develop new bivariate continuous and discrete G families of probability distributions. Derive beneficial mathematical properties such as ordinary and incomplete moments, moment generating functions, residual life and reversed residual life functions, order statistics, quantile spread ordering and entropies, and some bivariate and multivariate extensions of the new and existing models using a simple-type copula.
G Is for One Gzonk!: An Alpha-number-bet Book
by Tony Diterlizzi Tiny DiterlooneyAges 4-7 Welcome to my silly dilly take on ABC. It's lots of fun and really odd, as you will quickly see. For they're no "leaping lizards" here. No "bears that bounce a ball." In fact, these zany critters have never been seen at all. So turn the page and cast a gaze on this menagerie, but don't forget the beasts within were all made up by me! - Tiny DiTerlooney
G.W. Leibniz, Interrelations between Mathematics and Philosophy
by Norma B. Goethe Philip Beeley David RabouinUp to now there have been scarcely any publications on Leibniz dedicated to investigating the interrelations between philosophy and mathematics in his thought. In part this is due to the previously restricted textual basis of editions such as those produced by Gerhardt. Through recent volumes of the scientific letters and mathematical papers series of the Academy Edition scholars have obtained a much richer textual basis on which to conduct their studies - material which allows readers to see interconnections between his philosophical and mathematical ideas which have not previously been manifested. The present book draws extensively from this recently published material. The contributors are among the best in their fields. Their commissioned papers cover thematically salient aspects of the various ways in which philosophy and mathematics informed each other in Leibniz's thought.

GDP: A Brief but Affectionate History - Revised and expanded Edition
by Diane CoyleHow GDP came to rule our lives—and why it needs to changeWhy did the size of the U.S. economy increase by 3 percent on one day in mid-2013—or Ghana's balloon by 60 percent overnight in 2010? Why did the U.K. financial industry show its fastest expansion ever at the end of 2008—just as the world’s financial system went into meltdown? And why was Greece’s chief statistician charged with treason in 2013 for apparently doing nothing more than trying to accurately report the size of his country’s economy? The answers to all these questions lie in the way we define and measure national economies around the world: Gross Domestic Product. This entertaining and informative book tells the story of GDP, making sense of a statistic that appears constantly in the news, business, and politics, and that seems to rule our lives—but that hardly anyone actually understands.Diane Coyle traces the history of this artificial, abstract, complex, but exceedingly important statistic from its eighteenth- and nineteenth-century precursors through its invention in the 1940s and its postwar golden age, and then through the Great Crash up to today. The reader learns why this standard measure of the size of a country’s economy was invented, how it has changed over the decades, and what its strengths and weaknesses are. The book explains why even small changes in GDP can decide elections, influence major political decisions, and determine whether countries can keep borrowing or be thrown into recession. The book ends by making the case that GDP was a good measure for the twentieth century but is increasingly inappropriate for a twenty-first-century economy driven by innovation, services, and intangible goods.
