Partial Least Squares Structural Equation Modeling: Recent Advances in Banking and Finance (International Series in Operations Research & Management Science #267)
by Christian M. Ringle Necmi K. AvkiranThis book pulls together robust practices in Partial Least Squares Structural Equation Modeling (PLS-SEM) from other disciplines and shows how they can be used in the area of Banking and Finance. In terms of empirical analysis techniques, Banking and Finance is a conservative discipline. As such, this book will raise awareness of the potential of PLS-SEM for application in various contexts. PLS-SEM is a non-parametric approach designed to maximize explained variance in latent constructs. Latent constructs are directly unobservable phenomena such as customer service quality and managerial competence. Explained variance refers to the extent we can predict, say, customer service quality, by examining other theoretically related latent constructs such as conduct of staff and communication skills. Examples of latent constructs at the microeconomic level include customer service quality, managerial effectiveness, perception of market leadership, etc.; macroeconomic-level latent constructs would be found in contagion of systemic risk from one financial sector to another, herd behavior among fund managers, risk tolerance in financial markets, etc. Behavioral Finance is bound to provide a wealth of opportunities for applying PLS-SEM. The book is designed to expose robust processes in application of PLS-SEM, including use of various software packages and codes, including R. PLS-SEM is already a popular tool in marketing and management information systems used to explain latent constructs. Until now, PLS-SEM has not enjoyed a wide acceptance in Banking and Finance. Based on recent research developments, this book represents the first collection of PLS-SEM applications in Banking and Finance. This book will serve as a reference book for those researchers keen on adopting PLS-SEM to explain latent constructs in Banking and Finance.
Partitions, Hypergeometric Systems, and Dirichlet Processes in Statistics (SpringerBriefs in Statistics #0)
by Shuhei ManoThis book focuses on statistical inferences related to various combinatorial stochastic processes. Specifically, it discusses the intersection of three subjects that are generally studied independently of each other: partitions, hypergeometric systems, and Dirichlet processes. The Gibbs partition is a family of measures on integer partition, and several prior processes, such as the Dirichlet process, naturally appear in connection with infinite exchangeable Gibbs partitions. Examples include the distribution on a contingency table with fixed marginal sums and the conditional distribution of Gibbs partition given the length. The A-hypergeometric distribution is a class of discrete exponential families and appears as the conditional distribution of a multinomial sample from log-affine models. The normalizing constant is the A-hypergeometric polynomial, which is a solution of a system of linear differential equations of multiple variables determined by a matrix A, called A-hypergeometric system. The book presents inference methods based on the algebraic nature of the A-hypergeometric system, and introduces the holonomic gradient methods, which numerically solve holonomic systems without combinatorial enumeration, to compute the normalizing constant. Furher, it discusses Markov chain Monte Carlo and direct samplers from A-hypergeometric distribution, as well as the maximum likelihood estimation of the A-hypergeometric distribution of two-row matrix using properties of polytopes and information geometry. The topics discussed are simple problems, but the interdisciplinary approach of this book appeals to a wide audience with an interest in statistical inference on combinatorial stochastic processes, including statisticians who are developing statistical theories and methodologies, mathematicians wanting to discover applications of their theoretical results, and researchers working in various fields of data sciences.

Path Coupling and Aggregate Path Coupling (SpringerBriefs in Probability and Mathematical Statistics)
by Yevgeniy Kovchegov Peter T. OttoThis book describes and characterizes an extension to the classical path coupling method applied to statistical mechanical models, referred to as aggregate path coupling. In conjunction with large deviations estimates, the aggregate path coupling method is used to prove rapid mixing of Glauber dynamics for a large class of statistical mechanical models, including models that exhibit discontinuous phase transitions which have traditionally been more difficult to analyze rigorously. The book shows how the parameter regions for rapid mixing for several classes of statistical mechanical models are derived using the aggregate path coupling method.

The content mainly focuses on kinetic equations and mean field games, which provide a solid framework for the description of multi-agent phenomena. The book includes original contributions on the theoretical and numerical study of the MFG system: the uniqueness issue and finite difference methods for the MFG system, MFG with state constraints, and application of MFG to market competition. The book also presents new contributions on the analysis and numerical approximation of the Fokker-Planck-Kolmogorov equations, the isotropic Landau model, the dynamical approach to the quantization problem and the asymptotic methods for fully nonlinear elliptic equations. Chiefly intended for researchers interested in the mathematical modeling of collective phenomena, the book provides an essential overview of recent advances in the field and outlines future research directions.
Pedagogical Content Knowledge in STEM: Research to Practice (Advances in STEM Education)
by Stephen Miles Uzzo Sherryl Browne Graves Erin Shay Marisa Harford Robert ThompsonThis volume represents both recent research in pedagogical content knowledge (PCK) in science, technology, engineering and math (STEM), as well as emerging innovations in how PCK is applied in practice. The notion of “research to practice” is critical to validating how effectively PCK works within the clinic and how it can be used to improve STEM learning. As the need for more effective educational approaches in STEM grows, the importance of developing, identifying, and validating effective practices and practitioner competencies are needed. This book covers a wide range of topics in PCK in different school levels (middle school, college teacher training, teacher professional development), and different environments (museums, rural). The contributors believe that vital to successful STEM education practice is recognition that STEM domains require both specialized domain knowledge as well as specialized pedagogical approaches. The authors of this work were chosen because of their extensive fieldwork in PCK research and practice, making this volume valuable to furthering how PCK is used to enlighten the understanding of learning, as well as providing practical instruction. This text helps STEM practitioners, researchers, and decision-makers further their interest in more effective STEM education practice, and raises new questions about STEM learning.
Periodic Character and Patterns of Recursive Sequences
by Michael A. RadinThis textbook on periodic character and patterns of recursive sequences focuses on discrete periodic patterns of first order, second order and higher order difference equations. Aimed toward advanced undergraduate students and graduate students who have taken a basic course in Calculus I and Discrete Mathematics, this book serves as a core text for a course in Difference Equations and Discrete Dynamical Systems. The text contains over 200 exercises to provide readers with a hands-on experience working with the material; the exercises include computations of specific examples and proofs of general results. Readers will receive a first-hand introduction to patterns of periodic cycles and patterns of transient terms with exercises for most sections of the text, preparing them for significant research work in the area.
Permutation Groups and Cartesian Decompositions (London Mathematical Society Lecture Note Ser. #449)
by Cheryl E. Praeger Csaba SchneiderPermutation groups, their fundamental theory and applications are discussed in this introductory book. It focuses on those groups that are most useful for studying symmetric structures such as graphs, codes and designs. Modern treatments of the O'Nan–Scott theory are presented not only for primitive permutation groups but also for the larger families of quasiprimitive and innately transitive groups, including several classes of infinite permutation groups. Their precision is sharpened by the introduction of a cartesian decomposition concept. This facilitates reduction arguments for primitive groups analogous to those, using orbits and partitions, that reduce problems about general permutation groups to primitive groups. The results are particularly powerful for finite groups, where the finite simple group classification is invoked. Applications are given in algebra and combinatorics to group actions that preserve cartesian product structures. Students and researchers with an interest in mathematical symmetry will find the book enjoyable and useful.
Perturbed Gradient Flow Trees and A∞-algebra Structures in Morse Cohomology (Atlantis Studies In Dynamical Systems Ser. #6)
by Stephan MescherThis book elaborates on an idea put forward by M. Abouzaid on equipping the Morse cochain complex of a smooth Morse function on a closed oriented manifold with the structure of an A∞-algebra by means of perturbed gradient flow trajectories. This approach is a variation on K. Fukaya’s definition of Morse-A∞-categories for closed oriented manifolds involving families of Morse functions. To make A∞-structures in Morse theory accessible to a broader audience, this book provides a coherent and detailed treatment of Abouzaid’s approach, including a discussion of all relevant analytic notions and results, requiring only a basic grasp of Morse theory. In particular, no advanced algebra skills are required, and the perturbation theory for Morse trajectories is completely self-contained.In addition to its relevance for finite-dimensional Morse homology, this book may be used as a preparation for the study of Fukaya categories in symplectic geometry. It will be of interest to researchers in mathematics (geometry and topology), and to graduate students in mathematics with a basic command of the Morse theory.
The Philosophers and Mathematics: Festschrift for Roshdi Rashed (Logic, Epistemology, and the Unity of Science #43)
by Hassan TahiriThis book explores the unique relationship between two different approaches to understand the nature of knowledge, reality, and existence. It collects essays that examine the distinctive historical relationship between mathematics and philosophy. Readers learn what key philosophers throughout the ages thought about mathematics. This includes both thinkers who recognized the relevance of mathematics to their own work as well as those who chose to completely ignore its many achievements.The essays offer insight into the role that mathematics played in the formation of each included philosopher’s doctrine as well as the impact its remarkable expansion had on the philosophical systems each erected. Conversely, the authors also highlight the ways that philosophy contributed to the growth and transformation of mathematics. Throughout, significant historical examples help to illustrate these points in a vivid way. Mathematics has often been a favored interlocutor of philosophers and a major source of inspiration. This book is the outcome of an international conference held in honor of Roshdi Rashed, a renowned historian of mathematics. It provides researchers, students, and interested readers with remarkable insights into the history of an important relationship throughout the ages.
The Philosophy of Logical Atomism: A Centenary Reappraisal (History of Analytic Philosophy)
by Landon D. Elkind Gregory LandiniThis book offers a comprehensive critical survey of issues of historical interpretation and evaluation in Bertrand Russell's 1918 logical atomism lectures and logical atomism itself. These lectures record the culmination of Russell's thought in response to discussions with Wittgenstein on the nature of judgement and philosophy of logic and with Moore and other philosophical realists about epistemology and ontological atomism, and to Whitehead and Russell’s novel extension of revolutionary nineteenth-century work in mathematics and logic. Russell's logical atomism lectures have had a lasting impact on analytic philosophy and on Russell's contemporaries including Carnap, Ramsey, Stebbing, and Wittgenstein. Comprised of 14 original essays, this book will demonstrate how the direct and indirect influence of these lectures thus runs deep and wide.
The Philosophy of Mathematics Education Today (ICME-13 Monographs)
by Paul ErnestThis book offers an up-to-date overview of the research on philosophy of mathematics education, one of the most important and relevant areas of theory. The contributions analyse, question, challenge, and critique the claims of mathematics education practice, policy, theory and research, offering ways forward for new and better solutions. The book poses basic questions, including: What are our aims of teaching and learning mathematics? What is mathematics anyway? How is mathematics related to society in the 21st century? How do students learn mathematics? What have we learnt about mathematics teaching? Applied philosophy can help to answer these and other fundamental questions, and only through an in-depth analysis can the practice of the teaching and learning of mathematics be improved. The book addresses important themes, such as critical mathematics education, the traditional role of mathematics in schools during the current unprecedented political, social, and environmental crises, and the way in which the teaching and learning of mathematics can better serve social justice and make the world a better place for the future.
Philosophy's Loss of Logic to Mathematics: An Inadequately Understood Take-Over (Studies in Applied Philosophy, Epistemology and Rational Ethics #43)
by Woosuk ParkThis book offers a historical explanation of important philosophical problems in logic and mathematics, which have been neglected by the official history of modern logic. It offers extensive information on Gottlob Frege’s logic, discussing which aspects of his logic can be considered truly innovative in its revolution against the Aristotelian logic. It presents the work of Hilbert and his associates and followers with the aim of understanding the revolutionary change in the axiomatic method. Moreover, it offers useful tools to understand Tarski’s and Gödel’s work, explaining why the problems they discussed are still unsolved. Finally, the book reports on some of the most influential positions in contemporary philosophy of mathematics, i.e., Maddy’s mathematical naturalism and Shapiro’s mathematical structuralism. Last but not least, the book introduces Biancani’s Aristotelian philosophy of mathematics as this is considered important to understand current philosophical issue in the applications of mathematics. One of the main purposes of the book is to stimulate readers to reconsider the Aristotelian position, which disappeared almost completely from the scene in logic and mathematics in the early twentieth century.
Phonon Thermal Transport in Silicon-Based Nanomaterials (SpringerBriefs in Physics)
by Hai-Peng Li Rui-Qin ZhangIn this Brief, authors introduce the advance in theoretical and experimental techniques for determining the thermal conductivity in nanomaterials, and focus on review of their recent theoretical studies on the thermal properties of silicon–based nanomaterials, such as zero–dimensional silicon nanoclusters, one–dimensional silicon nanowires, and graphenelike two–dimensional silicene. The specific subject matters covered include: size effect of thermal stability and phonon thermal transport in spherical silicon nanoclusters, surface effects of phonon thermal transport in silicon nanowires, and defects effects of phonon thermal transport in silicene. The results obtained are supplemented by numerical calculations, presented as tables and figures. The potential applications of these findings in nanoelectrics and thermoelectric energy conversion are also discussed. In this regard, this Brief represents an authoritative, systematic, and detailed description of the current status of phonon thermal transport in silicon–based nanomaterials. This Brief should be a highly valuable reference for young scientists and postgraduate students active in the fields of nanoscale thermal transport and silicon-based nanomaterials.
Physical (A)Causality
by Karl SvozilThis open access book addresses the physical phenomenon of events that seem to occur spontaneously and without any known cause. These are to be contrasted with events that happen in a (pre-)determined, predictable, lawful, and causal way. All our knowledge is based on self-reflexive theorizing, as well as on operational means of empirical perception. Some of the questions that arise are the following: are these limitations reflected by our models? Under what circumstances does chance kick in? Is chance in physics merely epistemic? In other words, do we simply not know enough, or use too crude levels of description for our predictions? Or are certain events "truly", that is, irreducibly, random? The book tries to answer some of these questions by introducing intrinsic, embedded observers and provable unknowns; that is, observables and procedures which are certified (relative to the assumptions) to be unknowable or undoable. A (somewhat iconoclastic) review of quantum mechanics is presented which is inspired by quantum logic. Postulated quantum (un-)knowables are reviewed. More exotic unknowns originate in the assumption of classical continua, and in finite automata and generalized urn models, which mimic complementarity and yet maintain value definiteness. Traditional conceptions of free will, miracles and dualistic interfaces are based on gaps in an otherwise deterministic universe.
Physical Perspectives on Computation, Computational Perspectives on Physics

Physics of Oscillations and Waves: With Use Of Matlab And Python (Undergraduate Texts In Physics Ser.)
by Arnt Inge VistnesIn this textbook a combination of standard mathematics and modern numerical methods is used to describe a wide range of natural wave phenomena, such as sound, light and water waves, particularly in specific popular contexts, e.g. colors or the acoustics of musical instruments. It introduces the reader to the basic physical principles that allow the description of the oscillatory motion of matter and classical fields, as well as resulting concepts including interference, diffraction, and coherence. Numerical methods offer new scientific insights and make it possible to handle interesting cases that can’t readily be addressed using analytical mathematics; this holds true not only for problem solving but also for the description of phenomena. Essential physical parameters are brought more into focus, rather than concentrating on the details of which mathematical trick should be used to obtain a certain solution. Readers will learn how time-resolved frequency analysis offers a deeper understanding of the interplay between frequency and time, which is relevant to many phenomena involving oscillations and waves. Attention is also drawn to common misconceptions resulting from uncritical use of the Fourier transform. The book offers an ideal guide for upper-level undergraduate physics students and will also benefit physics instructors. Program codes in Matlab and Python, together with interesting files for use in the problems, are provided as free supplementary material.
Pieces and Parts in Scientific Texts (Why the Sciences of the Ancient World Matter #1)
by Florence Bretelle-Establet Stéphane SchmittThis book starts from a first general observation: there are very diverse ways to frame and convey scientific knowledge in texts. It then analyzes texts on mathematics, astronomy, medicine and life sciences, produced in various parts of the globe and in different time periods, and examines the reasons behind the segmentation of texts and the consequences of such textual divisions. How can historians and philosophers of science approach this diversity, and what is at stake in dealing with it? The book addresses these questions, adopting a specific approach to do so. In order to shed light on the diversity of organizational patterns and rhetorical strategies in scientific texts, and to question the rationale behind the choices made to present such texts in one particular way, it focuses on the issue of text segmentation, offering answers to questions such as: What was the meaning of segmenting texts into paragraphs, chapters, sections and clusters? Was segmentation used to delimit self-contained units, or to mark breaks in the physical appearance of a text in order to aid reading and memorizing, or to cope with the constraints of the material supports? How, in these different settings and in different texts, were pieces and parts made visible?
El planeta vacío: El shock del declive de la población mundial
by Darrell Bricker John IbbitsonBienvenidos a la caída de la población mundial. Durante medio siglo, muchos estadistas, políticos, analistas y estudiosos han alertado sobre una explosión demográfica que pondrá en jaque los recursos del planeta. Sin embargo, un creciente número de expertos tiene en el punto de mira otro motivo de alarma: en lugar de aumentar exponencialmente, la población mundial se encamina hacia un fuerte descenso que ya es evidente en muchos lugares. En El planeta vacío, los autores revelan cómo esta caída de la población traerá consigo distintos beneficios: el riesgo de hambrunas disminuirá, la situación medioambiental mejorará, menos trabajadores exigirán mejores salarios y unas tasas de natalidad más bajas representarán mayores ingresos y autonomía para las mujeres. Pero no todo son buenas noticias. Ya podemos ver los efectos del envejecimiento de la población en Europa y algunos puntos de Asia, y cómo la escasez de trabajadores debilita la economía e impone unas exigencias desmesuradas en el campo de la salud pública. Reseñas...«Si bien el género "todo lo que sabes es falso" se ha vuelto agotador, este libro contiene información fascinante y de vital importancia. Los datos reveladores de Bricker e Ibbitson demuestran, con una prosa enérgica e incisiva, que en el mundo se está operando un cambio radical sin que nadie se dé cuenta.»Steven Pinker «Aun cuando la población mundial esté aumentando, la tasa de natalidad ya ha empezado a caer en todo el mundo. En otros tiempos, los descensos de población se debieron a desastres naturales como la erupción del Toba, la peste negra o la gripe, pero la caída que viene ahora será cosa exclusivamente nuestra. En este sugerente libro, Bricker e Ibbitson debaten acerca de por qué, hacia finales del siglo XXI, no habrá una superpoblación global sino una rápida disminución demográfica, al tiempo que proponen medios para adaptarnos a ella.»Lewis Dartnell, profesor de comunicación científica en la Universidad de Westminster y autor de Abrir en caso de apocalipsis «Para comprender el futuro debemos cuestionar nuestras suposiciones, y la mayor de todas es que la población sigue creciendo, algo que muchos creemos. Bricker e Ibbitson nos ofrecen un desafío revelador, que debería ser tomado muy en serio por todo aquel que se preocupe por el futuro a largo plazo (que, espero, seamos todos).»Dan Gardner, autor de Risk y coautor de Superforecasting: The Art and Science of Prediction «Un libro muy ameno, una visión controvertida sobre una realidad sobre la que se reflexiona poco: un mundo despoblado y una urbanización creciente.»George Magnus, autor de The Age of Aging y Red Flags: Why Xi's China Is in Jeopardy
Playful Disruption of Digital Media (Gaming Media and Social Effects Ser.)
by Daniel Cermak-SassenrathThis book starts with the proposition that digital media invite play and indeed need to be played by their everyday users. Play is probably one of the most visible and powerful ways to appropriate the digital world. The diverse, emerging practices of digital media appear to be essentially playful: Users are involved and active, produce form and content, spread, exchange and consume it, take risks, are conscious of their own goals and the possibilities of achieving them, are skilled and know how to acquire more skills. They share a perspective of can-do, a curiosity of what happens next? Play can be observed in social, economic, political, artistic, educational and criminal contexts and endeavours. It is employed as a (counter) strategy, for tacit or open resistance, as a method and productive practice, and something people do for fun.The book aims to define a particular contemporary attitude, a playful approach to media. It identifies some common ground and key principles in this novel terrain. Instead of looking at play and how it branches into different disciplines like business and education, the phenomenon of play in digital media is approached unconstrained by disciplinary boundaries. The contributions in this book provide a glimpse of a playful technological revolution that is a joyful celebration of possibilities that new media afford. This book is not a practical guide on how to hack a system or to pirate music, but provides critical insights into the unintended, artistic, fun, subversive, and sometimes dodgy applications of digital media.Contributions from Chris Crawford, Mathias Fuchs, Rilla Khaled, Sybille Lammes, Eva and Franco Mattes, Florian 'Floyd' Mueller, Michael Nitsche, Julian Oliver, and others cover and address topics such as reflective game design, identity and people's engagement in online media, conflicts and challenging opportunities for play, playing with cartographical interfaces, player-emergent production practices, the re-purposing of data, game creation as an educational approach, the ludification of society, the creation of meaning within and without play, the internalisation and subversion of roles through play, and the boundaries of play.

Did you know a quadrilateral—or a shape with four straight sides—can have several names? You can call one a parallelogram, a rhombus, a trapezoid, or even a square! What shapes can you recognize?
Polynomials and the mod 2 Steenrod Algebra: Representations of GL (London Mathematical Society Lecture Note Series #442)
by Grant Walker Reginald M. W. WoodThis is the first book to link the mod 2 Steenrod algebra, a classical object of study in algebraic topology, with modular representations of matrix groups over the field F of two elements. The link is provided through a detailed study of Peterson's `hit problem' concerning the action of the Steenrod algebra on polynomials, which remains unsolved except in special cases. The topics range from decompositions of integers as sums of 'powers of 2 minus 1', to Hopf algebras and the Steinberg representation of GL(n, F). Volume 1 develops the structure of the Steenrod algebra from an algebraic viewpoint and can be used as a graduate-level textbook. Volume 2 broadens the discussion to include modular representations of matrix groups. Algebraic and combinatorial treatment of Steenrod algebra. Accessible to those without a background in topology. Largely self-contained with detailed proofs.
