Accounting for Value
by Stephen PenmanDespite their skills and extensive training, many analysts fail to recognize the basics of good accounting and its deployment in valuation. By focusing on abstract concepts such as measurement basis, exit values, and entity concepts, they miss out on the benfits of a practical approach to valuation. While modern finance has advanced important concepts, including diversification and risk measurement, effective and efficient accounting merges these tools with fundamental analysis to divine a true account of value.Launching an innovative examination of equity valuation as a matter of accounting, Stephen Penman embraces the commonsense ideas of fundamentalists& mdash;good firms can be bad guys, the risk in investing is the risk of paying too much, ignore information at your own peril, beware of paying too much for growth& mdash;and combines them with the principles of modern finance to reestablish the parameters of good analysis. The result anchors the investor, guards against behavioral biases, and challenges speculation. Penman compares fair-value accounting and historical-cost accounting; describes the anchoring of cash flows, book value, and earnings; and details the failure of modern finance to correctly assess value. He concludes with fundamental strategies for accounting for value and a bold proposal for assessing the cost of capital. Altogether, Penman's text is an essential tool for interpreting the greatest financial challenges of our time: the stock market bubble of the 1990s, the credit crisis of 2008, and accounting in the wake of ongoing market instability.

Acculturation of Korean New Zealander Youth: Re-Ethnicization of the Newer Generation
by Changzoo SongThis open access book explores the acculturation, identity development, and cultural reconnection of newer-generation (1.5- and second-generation) Korean New Zealander youth who grew up in New Zealand after the 1990s. Based on in-depth interviews, it shows how many of them initially sought to assimilate into the dominant culture but later experienced a process of re-ethnicization, rediscovering their Korean heritage during adolescence and early adulthood. Chapters explore key themes such as cultural adaptation, ethnic identity, racism, co-ethnic friendships, and the role of digital media and the Korean Wave in fostering re-ethnicization. This book also situates these youth experiences within the broader contexts of New Zealand&’s multicultural policies, its bicultural foundation, multicultural frameworks and the global dynamics of diaspora and migration. Drawing on theories of segmented assimilation, transnationalism, and ethnic belonging, this book offers new insights into how young migrants navigate dual identities and negotiate belonging in an increasingly diverse and complex society for scholars and students in migration studies, sociology, diaspora studies, Asian studies and cultural studies.

Accuracy Verification Methods: Theory and Algorithms (Computational Methods in Applied Sciences #32)
by Pekka Neittaanmäki Olli Mali Sergey RepinThe importance of accuracy verification methods was understood at the very beginning of the development of numerical analysis. Recent decades have seen a rapid growth of results related to adaptive numerical methods and a posteriori estimates. However, in this important area there often exists a noticeable gap between mathematicians creating the theory and researchers developing applied algorithms that could be used in engineering and scientific computations for guaranteed and efficient error control. The goals of the book are to (1) give a transparent explanation of the underlying mathematical theory in a style accessible not only to advanced numerical analysts but also to engineers and students; (2) present detailed step-by-step algorithms that follow from a theory; (3) discuss their advantages and drawbacks, areas of applicability, give recommendations and examples.
Accurate Case Outcome Modeling: Entrepreneur Policy, Management, and Strategy Applications
by Arch G. WoodsideThis volume advocates accurate case outcome prediction that does not rely on symmetric modeling. To that end, it provides theory construction and testing applications in several sub-disciplines of business and the social sciences to illustrate how to move away from symmetric theory construction. Each chapter constructs case outcome theory and includes empirical analysis of outcomes. Chapter 1 provides a foundation of symmetric variable directional-relationship theory construction and null hypothesis significance testing versus asymmetric case outcome theory construction and somewhat precise outcome testing, while Chapters 2–6 investigate these principles through a range of applications.This volume will be very useful to researchers and professionals in manufacturing, service, consulting, management, marketing, organizational studies, and more. It will also be an excellent resource for advanced statistics students in building and testing case outcome models. Data sets are included so that readers can replicate findings presented in each chapter, and grow to present and test additional theories.

Achilles in the Quantum Universe: The Definitive History of Infinity
by Richard MorrisCenturies ago, when the ancient philosopher Zeno proposedhis famous paradox involving Achilles and the Tortoise, he struck at the heart of one of science's most enduring and intractable problems: How do we define the infinite? From then on, our greatest natural philosophers, logicians, mathematicians, and scientists, from Aristotle to Stephen Hawking, have been stymied-and driven-by infinity.Acclaimed Science writer Richard Morris guides us on a fascinating, literate and entertaining tour of the efforts made throughout history to make sense of the mind-bending concept of the infinite. In tracing this quest, Morris shows us how each new encounter with infinity drove the advancement of physics and mathematics. Along the way, we encounter such luminaries as Galileo and Newton, Tycho Brahe and Giordano Bruno, and the giants of modern physics: Planck, Einstein, Bohr, Feynmann, Hawking, and numerous others.Beginning with simple logical puzzles and progressing to the latest cosmological theories, Morris shows how these same infinity problems helped spawn such groundbreaking scientific developments as relativity and quantum mechanics. Though in many ways, the infinite is just as baffling today as it was in antiquity, contemporary scientists are probing ever deeper into the nature of our universe and catching fleeting glimpses of the infinite in ways the ancients could never have imagined.Ultimately, we see that hidden within the theoretical possibility of an infinite number of universes may lie the answers to some of humankind's most fundamental questions: Why is there something rather than nothing? Why are we here?
Achtung: 150 Kolumnen zum Nachdenken und Schmunzeln
by Björn Christensen Sören ChristensenMit 150 Kolumnen ,,Achtung Statistik" bietet das Buch eine kurzweilige Möglichkeit, Statistik zukünftig mit anderen Augen zu sehen, kritisch zu hinterfragen und in Einzelfällen sogar wissenschaftliche Top-Nachrichten mit gesundem Menschenverstand als statistische ,,Rohrkrepierer" zu entlarven. Geprägt durch den Spruch: ,,Trau keiner Statistik, die du nicht selbst gefälscht hast!" hat die Statistik wirklich keinen guten Ruf. Sie gilt als eine trockene, schwierige Materie, die uns zwar auf Schritt und Tritt in Schule, Studium und Beruf, aber auch in den Medien begegnet, zu der die meisten aber kaum Zugang finden. Die Autoren zeigen, dass es möglich ist, ohne besondere Vorbildung und mit einem Schmunzeln interessante und erstaunliche statistische Erkenntnisse zu gewinnen, zu deren Verständnis keine Formeln nötig sind. Die seit 2012 regelmäßig im ,,Schleswig-Holstein Journal" publizierten Kolumnen wurden für das Buch um weitergehende Erläuterungen und Beispiele ergänzt.
Achtung: 150 neue Kolumnen zum Nachdenken und Schmunzeln
by Björn Christensen Sören ChristensenStatistik und Mathematik prägen unser Leben so stark wie noch nie. Trotzdem gilt die Welt der Zahlen und Strukturen oft als abstrakt und kompliziert. Dieses Buch tritt den Gegenbeweis an: Die Autoren zeigen auf unterhaltsame Art, wie man – ganz ohne Formeln und besondere Vorbildung – erstaunliche statistische und mathematische Erkenntnisse gewinnen kann. Grundlage dafür bilden 150 auf SPIEGEL ONLINE und im „Schleswig-Holstein Journal“ publizierte Kolumnen, die für das Buch teilweise kommentiert und ergänzt wurden. Die Zusammenstellung lädt dazu ein, zwischen den einzelnen Kapiteln und Abschnitten hin- und her zu springen, darin zu schmökern und fast beiläufig den eigenen „gesunden Menschenverstand“ zu schulen. Das Buch führt somit das erfolgreiche Konzept des bereits veröffentlichten Werks „Achtung: Statistik“ mit neuen Inhalten und erweitertem inhaltlichem Fokus fort.
Acid Stimulation Simulation Theory and Application in Carbonate Rocks
by Jun Yao Cunqi Jia Kamy SepehrnooriThis book provides a theoretical basis and technical support for carbonate acid stimulation design. Carbonate reservoirs are one of the most important sources of fossil fuels. Acid stimulation is an effective technique for enhancing reservoir performance and boosting production. The book stands as a fundamental guide in implementing acid stimulation techniques in carbonate reservoirs. It models the acid stimulation process, contemplating mass, momentum, and energy changes alongside the real mineral composition of the carbonate rock matrix. Comprehensive sensitivity studies are conducted to elucidate the targeted mechanisms and optimization principles for designing acid stimulation applications in carbonate reservoirs. This book also serves as an excellent foundation for numerical simulation, providing detailed descriptions of how finite volume methods and sequential decoupling algorithms are utilized for numerical discretization and solving decoupled solutions on staggered grids. This book is an essential reference for reservoir engineers, academics, and students interested in studying and performing acid stimulation in carbonate reservoirs. It also helps readers obtain an understanding of modeling reactive flow in porous media with coupling multi-physical fields, including hydrologic–chemical-thermal processes and multi-scale characteristics. In addition, this book also delves into scale-up methods, such as the fundamental theoretical foundations and important theorems of the volume averaging approach. The book is used as a textbook for senior undergraduate and graduate courses in petroleum engineering.
Acoustic Analysis and Design of Short Elliptical End-Chamber Mufflers
by Akhilesh MimaniThis book presents a three-dimensional analysis of acoustic wave propagation in an elliptical waveguide, and applies the equations and concepts to design axially short elliptical end-chamber muffler configurations which are an important component of a complex multi-pass muffler used in a modern-day automotive exhaust system. A general solution of the Helmholtz equation in elliptical cylindrical co-ordinates is presented in terms of the Mathieu and modified Mathieu modal functions. This is followed by the tabulation and analysis, for the first time, of the non-dimensional resonance frequencies of the transverse modes of a rigid-wall elliptical waveguide for a complete range of aspect ratio. The modal shape patterns of the first few circumferential, radial and cross-modes are examined with particular attention to the pressure nodal ellipses and hyperbolae. An analytical formulation is then outlined for characterizing a single-inlet and single-outlet elliptical muffler with the inlet located on the end face and the outlet located either on the end face or side-surface. The ensuing chapter is devoted toward analyzing the Transmission Loss (TL) performance of different short end-chamber mufflers, namely (a) the straight-flow configuration having ports located on the opposite face, (b) the flow-reversal configuration with ports located on the same end face and (c) configuration with inlet port on the end face and outlet on the side surface. Design guidelines are formulated in terms of the optimal location of inlet and outlet ports which suppresses the deteriorating influence of certain higher-order modes, thereby delivering a broadband TL performance. Directions for future work are discussed toward the end. In summary, this book is a one-stop solution for a practicing automotive engineer designing mufflers, for an applied mathematician studying wave propagation in elliptical geometries, and also as a niche area within noise control engineering.
