This book guides you through an enjoyable journey, step by step, into the future. A team of fictional characters is introduced to share their learning and working experiences with the readers. In the beginning of the book, you will take the first step by learning the most basic models for one-period forecasts based on past performance of a market. You will also learn how to evaluate your newly built models. Next, you will progress further into intermediate-level models, including multi-period forecasts based on past performance of a market or based on an external factor. It also introduces interval forecasting, which allows you to obtain a range of forecast values instead of a single value in the future. In the second half, you will familiarize yourself with advanced models that provide multi-period forecasts based on multiple internal or external factors. Toward the end, you will learn several applied models in business and economics that will facilitate you with practical applications related to real life situations. The last chapter summarizes all models introduced in this book and provides a table of references for finding the most important concepts, tables, and figures in the book so that you can recall every step of your adventure.

The volume is full of examples and practical guidance on how to perform data analyses using Microsoft Excel.
The first part of this book provides a self-contained and accessible introduction to the subject in the general setting of pseudo-Riemannian manifolds and their non-degenerate submanifolds, only assuming from the reader some basic knowledge about manifold theory. A number of recent results on pseudo-Riemannian submanifolds are also included.The second part of this book is on δ-invariants, which was introduced in the early 1990s by the author. The famous Nash embedding theorem published in 1956 was aimed for, in the hope that if Riemannian manifolds could be regarded as Riemannian submanifolds, this would then yield the opportunity to use extrinsic help. However, this hope had not been materialized as pointed out by M Gromov in his 1985 article published in Asterisque. The main reason for this is the lack of control of the extrinsic invariants of the submanifolds by known intrinsic invariants. In order to overcome such difficulties, as well as to provide answers for an open question on minimal immersions, the author introduced in the early 1990s new types of Riemannian invariants, known as δ-invariants, which are very different in nature from the classical Ricci and scalar curvatures. At the same time he was able to establish general optimal relations between δ-invariants and the main extrinsic invariants. Since then many new results concerning these δ-invariants have been obtained by many geometers. The second part of this book is to provide an extensive and comprehensive survey over this very active field of research done during the last two decades.
The book aims to present a comprehensive survey on biharmonic submanifolds and maps from the viewpoint of Riemannian geometry. It provides some basic knowledge and tools used in the study of the subject as well as an overall picture of the development of the subject with most up-to-date important results.Biharmonic submanifolds are submanifolds whose isometric immersions are biharmonic maps, thus biharmonic submanifolds include minimal submanifolds as a subclass. Biharmonic submanifolds also appeared in the study of finite type submanifolds in Euclidean spaces.Biharmonic maps are maps between Riemannian manifolds that are critical points of the bienergy. They are generalizations of harmonic maps and biharmonic functions which have many important applications and interesting links to many areas of mathematics and theoretical physics.Since 2000, biharmonic submanifolds and maps have become a vibrant research field with a growing number of researchers around the world, with many interesting results have been obtained.This book containing basic knowledge, tools for some fundamental problems and a comprehensive survey on the study of biharmonic submanifolds and maps will be greatly beneficial for graduate students and beginning researchers who want to study the subject, as well as researchers who have already been working in the field.
The study of directed graphs (digraphs) has developed enormously over recent decades, yet the results are rather scattered across the journal literature. This is the first book to present a unified and comprehensive survey of the subject. In addition to covering the theoretical aspects, the authors discuss a large number of applications and their generalizations to topics such as the traveling salesman problem, project scheduling, genetics, network connectivity, and sparse matrices. Numerous exercises are included. For all graduate students, researchers and professionals interested in graph theory and its applications, this book will be essential reading.
The purpose of this book is to introduce the reader to two interesting topics in geometry which have developed over the last fifteen years, namely, total mean curvature and submanifolds of finite type. The theory of total mean curvature is the study of the integral of the n-th power of the mean curvature of a compact n-dimensional submanifold in a Euclidean m-space and its applications to other branches of mathematics. The relation of total mean curvature to analysis, geometry and topology are discussed in detail. Motivated from these studies, the author introduces and studies submanifolds of finite type in the last chapter. Some applications of such submanifolds are also given. This book is self-contained. The author hopes that the reader will be encouraged to pursue his studies beyond the confines of the present book.
A warped product manifold is a Riemannian or pseudo-Riemannian manifold whose metric tensor can be decomposed into a Cartesian product of the y geometry and the x geometry — except that the x-part is warped, that is, it is rescaled by a scalar function of the other coordinates y. The notion of warped product manifolds plays very important roles not only in geometry but also in mathematical physics, especially in general relativity. In fact, many basic solutions of the Einstein field equations, including the Schwarzschild solution and the Robertson-Walker models, are warped product manifolds.The first part of this volume provides a self-contained and accessible introduction to the important subject of pseudo-Riemannian manifolds and submanifolds. The second part presents a detailed and up-to-date account on important results of warped product manifolds, including several important spacetimes such as Robertson-Walker's and Schwarzschild's.The famous John Nash's embedding theorem published in 1956 implies that every warped product manifold can be realized as a warped product submanifold in a suitable Euclidean space. The study of warped product submanifolds in various important ambient spaces from an extrinsic point of view was initiated by the author around the beginning of this century.The last part of this volume contains an extensive and comprehensive survey of numerous important results on the geometry of warped product submanifolds done during this century by many geometers.
Substantially revised, reorganised and updated, the second edition now comprises eighteen chapters, carefully arranged in a straightforward and logical manner, with many new results and open problems. As well as covering the theoretical aspects of the subject, with detailed proofs of many important results, the authors present a number of algorithms, and whole chapters are devoted to topics such as branchings, feedback arc and vertex sets, connectivity augmentations, sparse subdigraphs with prescribed connectivity, and also packing, covering and decompositions of digraphs. Throughout the book, there is a strong focus on applications which include quantum mechanics, bioinformatics, embedded computing, and the travelling salesman problem. Detailed indices and topic-oriented chapters ease navigation, and more than 650 exercises, 170 figures and 150 open problems are included to help immerse the reader in all aspects of the subject.

Interconnections between graph classes are also provided to make the book useful to a variety of readers.
The design of approximation algorithms for spanning tree problems has become an exciting and important area of theoretical computer science and also plays a significant role in emerging fields such as biological sequence alignments and evolutionary tree construction. While work in this field remains quite active, the time has come to collect under
Henry Mancini's Peter Gunn theme. Lalo Schifrin's Mission: Impossible theme. Isaac Hayes' theme from Shaft. These iconic melodies have remained a part of the pop culture landscape since their debuts back when movie studios and TV production companies employed full orchestral ensembles to provide a jazz backdrop for the suspenseful adventures of secret agents, private detectives, cops, spies and heist-minded criminals. Hundreds of additional films and television shows made from the mid-1950s and beyond have been propelled by similarly swinging title themes and underscores, many of which have (undeservedly) faded into obscurity. This meticulously researched book begins with Hayes' game-changing music for Shaft, and honors the careers of traditional jazz composers who--as the 1970s gave way to the '80s and beyond--resolutely battled against the pernicious influx of synth, jukebox scores and a growing corporate disinterest in lavish ensembles. Fans frustrated by the lack of attention paid to jazz soundtrack composers--including Mort Stevens, Laurie Johnson, Mike Post, Earle Hagen, David Shire, Elmer Bernstein and many, many others--will find solace in these pages (along with all the information needed to enhance one's music library). But this is only half the story; the saga's origins are discussed in this book's companion volume, Crime and Action Jazz on Screen: 1950-1970.
International Remittance Payments are described mainly as money sent by immigrants to their families and friends in their home countries. These payments provide an important source of income that is mostly used to provide for a variety of basic needs of the non-migrating members of immigrant families and thus remittance payments can be considered as a tool to reduce the poverty level of the labor sending countries. However, remittances are also used for asset accumulation by some families and for some countries they constitute a good part of foreign funds coming into the country. In-spite of their increasing volume over the last few decades, a lot of things about remittances are not known and studies estimate that about half of these money transfers are not even recorded. Since these payments are shown to reduce poverty and help economic progress in the remittance receiving countries, a better knowledge about remittances would help the debates surrounding immigration, remittances and their relation to the global economy. This book provides an overview of remittances in different parts of the world over the last thirty years. It looks at the labor sending and labor receiving countries separately. The text examines the trends, uses, motivations behind sending remittances, cost of sending them and how they are affected by the nature and the development level of different institutional factors. The remittance flows are growing over time and they are used mostly for reducing the uncertainty of life in the less developed parts of the world. However, motivation for sending remittances could be improved and thus remittances could be more conducive to economic development if 1) the relation between the remittance decision and the migration decision is better understood and 2) the costs of international money transfers are reduced. More studies about those issues would benefit the international community. Efforts should be made in all fronts to encourage such international flow of funds not only to have a redistribution of income all over the world, but also to synchronize the efforts towards global economic development and a better integration of the world economy. This book is aimed researchers, policy practitioners and post graduates studying International Economics or International Economic Relations or Political Science or Economic Development.
Theory of Electroelasticity analyzes the stress, strain, electric field and electric displacement in electroelastic structures such as sensors, actuators and other smart materials and structures. This book also describes new theories such as the physical variational principle and the inertial entropy theory. It differs from the traditional method by using the physical variational principle to derive the governing equations of the piezoelectric material, whereas the Maxwell stress is obtained automatically. By using the inertial entropy theory, the temperature wave equation is obtained very easily. The book is intended for scientists, researchers and engineers in the areas of mechanics, physics, smart material and control engineering as well as mechanical, aeronautical and civil engineering, etc. Zhen-Bang Kuang is a professor at Shanghai Jiao Tong University.

The longstanding biharmonic conjecture of the author's and the generalized biharmonic conjectures are also presented in details. This book will be of use to graduate students and researchers in the field of geometry.
The advances in sensor design have decreased the size, weight, and cost of sensors by orders of magnitude, yet with the increase of higher spatial and temporal re- lution and accuracy. With the fast progress of sensors design and communications technique, sensor networks have also been quickly evolving in both research and practical domains in the last decade. More and more sensor networks have been - ployed in real-world to gather information for our daily life. Applications of sensor networks can be found in battle?eld surveillance, environmental monitoring, b- logical detection, smart spaces, industrial diagnostics, etc. Although the technique of sensor networks has a very promising future, many challenges are still deserving lots of research efforts for its successful applications. Thisbookisdevotedtocoveragecontrol,oneofthemostfundamentalandimportant research issues in sensor networks. The aim of the book is to provide tutorial-like and up-to-date reference resources on various coverage control problems in sensor networks, a hot topic that has been intensively researched in recent years. Due to some unique characteristics of sensor networks such as energy constraint and - hoc topology, the coverage problems in sensor networks have many new scenarios and features that entitle them an important research issue in recent years. I have done my best to include in the book the most recent advances, techniques, protocols, results, and ?ndings in this ?eld.
Expanded to include a broader range of problems than the bestselling first edition, Finite Element Method Using MATLAB: Second Edition presents finite element approximation concepts, formulation, and programming in a format that effectively streamlines the learning process.

This treatise is further enriched by theoretical concepts/ models in disasters along with an analysis that integrates the results/findings with the theories that underpin them. Based on the research results, the author has produced a new disaster model that informs Relocation Decisions.
Professor Kun Huang is widely known for his collaboration with Max Born in writing the classic monograph, ?Dynamical Theory of Crystal Lattices?. During his years of active research, he has made many important contributions to solid state physics. The present collection of papers is selected at his own choice as representing his most influential works. Thus one finds included his pioneering work on the interaction of radiation field with polar lattices and the resulting coupled vibration modes (later known as ?polariton?); the systematic development of his theory of radiative and nonradiative multiphonon transition processes associated with lattice relaxation; his early prediction of diffuse X-ray scattering due to crystal defects; and his recent research works on low-dimensional semiconductor structures, etc.Professor Huang has found by his experience that scientists interested in these papers often want to know more particulars underlying the research work (background, motivation and rationale involved etc.). Thus he was led to write a commentary which is published alongside the papers.

There is a growing interest in firms' adoption of ethical and social marketing approaches among academics and practitioners alike. Ethical Marketing is the application of ethics into the marketing process, and Social Marketing is a concept that seeks to influence a target audience for the greater social good. Ethical and Social Marketing in Asia examines this so-far unexplored area, investigating why differing cultures and consumption behaviours require different emphasis in different markets. The diversity of the Asian countries provides a perplexing environment to the development and management of ethical and social marketing. The belief that bottom line profits is enough for a company, is often not favourably viewed by Asian countries emphasising collective, social and long term benefits for the people and country. Due to these interesting characteristics and complexities, the study of ethical and social marketing in Asia is a timely topic. The first chapters introduce Ethical Marketing in Asia, followed by case studies of how the approach is used across 14 diverse economies, geographically based on 'clusters'; North East, (China, Taiwan, Japan, South Korea), South East (Singapore, Malaysia, Thailand, Vietnam, Cambodia, the Philippines, Indonesia) and South Asia (India, Pakistan, Bangladesh). The second part discusses Social Marketing using the same sequence of regions and economies and the third part explores the unique link to Fairness Management in Asia, followed by a conclusion. - Explores the nature of ethical and social marketing from an Asian perspective - Discusses current ethical and social marketing researches and practices in different areas, industries, commercial and non-commercial sectors - Serves as an invaluable resource for marketing academics and practitioners requiring more than anecdotal evidence of different ethical and social marketing applications - Compares and contrasts unethical situations covering important aspects related to ethics, society and fairness - Includes an interesting mix of theory, research findings and practices
Most contemporary organizations use management teams to manage and coordinate their businesses at all levels of the organizational hierarchy. Management teams typically set overall goals, strategies, and priorities, making vital organizational decisions. They discuss issues, solve problems, offer advice, and ensure various processes and units are aligned and interact efficiently. Although management teams are vital for overall organizational performance, research indicates that they are largely underused and less effective than their potential would suggest for value creation. This book provides a research-based and practical model of the characteristics of effective management teams. It looks in depth at each factor of the model, discusses the supporting research, provides examples of how the factors influence the work and effectiveness of management teams, and shares tips and tools for successfully working with management team development. It provides researchers, academics, and students of organizational behavior with an overview of the variables that empirical research has found to be robustly related to management team effectiveness and will enable leaders and management consultants to develop more effective management teams.
