Consumer Demand in the United States

Consumer Demand in the United States

Lester D. Taylor; H.S. Houthakker

Springer-Verlag New York Inc.
2009
sidottu
A classic treatise that defined the field of applied demand analysis, Consumer Demand in the United States: Prices, Income, and Consumption Behavior is now fully updated and expanded for a new generation. Consumption expenditures by households in the United States account for about 70% of America’s GDP. The primary focus in this book is on how households adjust these expenditures in response to changes in price and income. Econometric estimates of price and income elasticities are obtained for an exhaustive array of goods and services using data from surveys conducted by the Bureau of Labor Statistics and aggregate consumption expenditures from the National Income and Product Accounts, providing a better understanding of consumer demand. Practical models for forecasting future price and income elasticities are also demonstrated. Fully revised with over a dozen new chapters and appendices, the book revisits the original Houthakker-Taylor models while examining new material as well, such as the use of quantile regression and the stationarity of consumer preference. It also explores the emerging connection between neuroscience and consumer behavior, integrating the economic literature on demand theory with psychology literature. The most comprehensive treatment of the topic to date, this volume will be an essential resource for any researcher, student or professional economist working on consumer behavior or demand theory, as well as investors and policymakers concerned with the impact of economic fluctuations.

Queueing Theory

Queueing Theory

Lester Lipsky

Springer-Verlag New York Inc.
2010
nidottu
Queueing Theory deals with systems where there is contention for resources, but the demands are only known probabilistically. This book can be considered to be a monograph or a textbook, and thus is aimed at two audiences: those who already know Queueing Theory but would like to know more of the Linear Algebraic Approach; and as a rst course for students who don't already have a strong background in probability, and feel more comfortable with algebraic arguments. Also, the equations are well suited to easy computation. In fact, there is much discussion on how various properties can be easily computed in any language that has automatic matrix operations (e.g., MATLAB). To help with physical insight, there are over 80 gures, numerous examples and exercises distributed throughout the book. There are, perhaps 50 books on QT that are available today, and most practitioners have several of them on their shelves. This book would be a good addition, as well as a good supplement to another text. This second edition has been updated throughout including a new chapter on Semi Markov Processes and new material on matrix representations of distributions and Power-tailed distribution. Lester Lipsky is a Professor in the Department of Computer Science and Engineering at the University of Connecticut.

Ultrasonic Nondestructive Evaluation Systems

Ultrasonic Nondestructive Evaluation Systems

Lester W. Schmerr Jr; Jung-Sin Song

Springer-Verlag New York Inc.
2010
nidottu
This book deals with ultrasonic nondestructive evaluation (NDE) inspections where high frequency waves are used to locate and characterize dangerous flaws (such as cracks) in materials. Ultrasonic NDE flaw inspections involve a very complex combination of electrical, electromechanical, and acoustic/elastic components so that it is important to understand the behavior of those components and their interactions in order to make quantitative flaw measurements. It will be shown that through the use of models and measurements it is now possible to characterize all the elements of an ultrasonic NDE flaw inspection system. Those elements include the pulser/receiver, the cabling, the transducers, and the wave propagation and scattering processes present in an ultrasonic NDE flaw measurement. It will also be demonstrated how to combine models and measurements of those elements to form ultrasonic measurement models which can simulate the flaw signals seen in ultrasonic NDE tests. This comprehensive modeling and measurement capability is described for the first time in this book. There are important engineering applications of this new tech- logy. For example, these ultrasonic models and measurements can be used to design new ultrasonic inspections as well as optimize existing ones. This technology can also help one to extract information on the nature of the flaw present from the measured ultrasonic flaw signals that can then be used to evaluate the safety and reliability of the material being inspected.

Values and Ethics in Social Work Practice

Values and Ethics in Social Work Practice

Lester Parrott

Learning Matters Ltd
2014
sidottu
Applying values and ethics to social work practice is taught widely across the qualifying degree programme, on both Masters and BA courses. This book is a clear introduction to this subject and will help students develop their understanding by showing social work students how ethics can have positive impacts on the lives of vulnerable people. There are chapters on how social workers can make good ethical and value-based decisions when working with risk, and how the role of the social worker as professional can impact on service users. Above all the book is a timely and clear introduction to the subject, with an emphasis on advocacy and empowerment and how the beginning social worker can start to apply these concepts.

Potential Theory

Potential Theory

Lester L. Helms

Springer London Ltd
2014
nidottu
Potential Theory presents a clear path from calculus to classical potential theory and beyond, with the aim of moving the reader into the area of mathematical research as quickly as possible. The subject matter is developed from first principles using only calculus. Commencing with the inverse square law for gravitational and electromagnetic forces and the divergence theorem, the author develops methods for constructing solutions of Laplace's equation on a region with prescribed values on the boundary of the region.The latter half of the book addresses more advanced material aimed at those with the background of a senior undergraduate or beginning graduate course in real analysis. Starting with solutions of the Dirichlet problem subject to mixed boundary conditions on the simplest of regions, methods of morphing such solutions onto solutions of Poisson's equation on more general regions are developed using diffeomorphisms and the Perron-Wiener-Brelot method, culminating in application to Brownian motion.In this new edition, many exercises have been added to reconnect the subject matter to the physical sciences. This book will undoubtedly be useful to graduate students and researchers in mathematics, physics and engineering.

Social Work and Poverty

Social Work and Poverty

Lester Parrott

Policy Press
2013
nidottu
Social work and poverty: A critical approach provides a timely review of the key issues facing social workers and service users in working together to combat poverty.First, it situates social work and poverty within a historical context, then analyses definitions and theories of poverty along with their importance in enabling anti-oppressive practice with service users. It goes on to evaluate the Welfare Reform Act 2012 in relation to the negative impact on service users and social workers alike. Key areas of social work and social care are covered with regard to the effects of poverty including, uniquely, access to food, obesity and problematic drug use. Finally the impacts of globalisation on social work and issues of poverty are explored. The book will be of interest to students, researchers and academics in social work and policy makers working in related areas.
