Book Description
Modern marketing techniques in industrialized countries cannot be implemented without segmentation of the potential market. Goods are no longer produced and sold without a significant consideration of customer needs combined with a recognition that these needs are heterogeneous. Since first emerging in the late 1950s, the concept of segmentation has been one of the most researched topics in the marketing literature. Segmentation has become a central topic to both the theory and practice of marketing, particularly in the recent development of finite mixture models to better identify market segments.Customer Reviews:

Linear Programming, Second Edition - Foundations and Extensions (International Series in Operations Research and Management Science, Volume 37) (International ... in Operations Research & Management Science)
Robert J. Vanderbei Manufacturer: Springer ProductGroup: Book Binding: Hardcover Similar Items:

ASIN: 0792373421 |
Book Description
Linear Programming: Foundations and Extensions is an introduction to the field of optimization. The book emphasizes constrained optimization, beginning with a substantial treatment of linear programming, and proceeding to convex analysis, network flows, integer programming, quadratic programming, and convex optimization.
The book is carefully written. Specific examples and concrete algorithms precede more abstract topics. Topics are clearly developed with a large number of numerical examples worked out in detail.
Moreover, Linear Programming: Foundations and Extensions underscores the purpose of optimization: to solve practical problems on a computer. Accordingly, the book is coordinated with free efficient C programs that implement the major algorithms studied:
-The two-phase simplex method; -The primal-dual simplex method; -The path-following interior-point method; -The homogeneous self-dual methods.
In addition, there are online JAVA applets that illustrate various pivot rules and variants of the simplex method, both for linear programming and for network flows. These C programs and JAVA tools can be found on the book's webpage:

Professor Robert Freund's review.......2004-04-30
Summary. This book presents a thoroughly modern treatment of linear programming that achieves a healthy balance between theory, implementation, computation, and between the simplex method and interior-point methods. It's most novel feature is that it is written in a delightful and refreshing conversational style, that bespeaks the author's teaching style and relaxed wit. It is a pleasure to read: students will find the book to be friendly and engaging, while professors will find in the book a wealth of teaching material, nicely organized and packaged for classroom use. The book is also meant to be used in conjunction with a public-available website that contains software for various algorithms, additional exercises, and demos of algorithms.
The need for new linear programming textbooks. The world of linear programming has changed dramatically in the last ten years. For one thing, the incredible changes in computer technology have made it easy to solve truly huge LPs, and routine LP problems solve in fractions of a second even on a personal computer. As a result, the study of linear programming algorithms is of less interest to the casual student. (In a similar vein, we usually do not teach students how to efficiently compute square roots; we simply presume they can press the right buttons on their calculator.) On the other hand, because we can now solve truly gigantic linear programs, issues of computer implementation, numerical stability, and software architecture, etc., are as important for the serious optimizer as is, say, duality theory. Furthermore, the development and recognition of the importance of interior point methods has changed the landscape of linear programming significantly, so that linear programming is no longer synonymous with the simplex method, and a modern treatment of LP must also present an in-depth treatment of the most important interior point methods.
Vanderbei's book is thoroughly modern. Vanderbei's book is completely up-to-date. Aside from a nice treatment of the simplex method, it also contains a very up-to-date treatment of interior point methods, including the homogeneous self-dual formulation and algorithm (which might soon become the dominant algorithm in practice and theory). It contains extensive material on issues of implementation of both the simplex algorithm and interior point algorithms. A politician might call it a book for the 21st century.
Vanderbei's book has many novel features. This book is quite different from most other textbooks on LP in a number of important ways. For starters, the standard form of a linear program in the book is the symmetric form of the problem (max c^T x | Ax <= b, x >= 0), as opposed to the usual form (min c^T x | Ax=b, x >= 0). This difference allows for an easier treatment of duality, and allows one to see the geometry of linear programming more easily as well. The symmetric form also makes it easier to set up the homogeneous self-dual interior point algorithm. However, this form has the drawback that discussions of bases, basic feasible solutions, and some of the mechanics of the simplex method are all a bit more awkward. (The book uses the language of dictionaries to describe the essential information in a simplex method iteration.) The book has more of a focus on engineering applications than does the more typcial LP textbook (which tend to rely on business problems). For example, there is a nice chapter on optimization of engineering structures such as trusses. The book gives a very broad treatment of interior point methods, including several topics that are not usually found in textbooks such as the homogeneous self-dual formulation and algorithm, quadratic programming via interior point methods, and general convex optimization via interior point methods.
These novel features are good in that the author has clearly tried to be innovative and to build an LP text from the ground up, without regard for past texts.
Some Nice Features. There are some particularly nice features in the book. The book contains a much-simplified variant of the Klee-Minty polytope that allows for a more straightforward proof that the simplex method can visit exponentially many extreme points. In addition to proving strong duality, the book also presents Tucker's strict complementarity theorem, which has become important in the new view of sensitivity analysis, optimal partitions, and interior point methods. The book also contains a nice treatment of the steepest edge pivot rule, which has recently emerged as an important component in speeding up the performance of the simplex algorithm. In the treatment of interior point methods, the author spends very little time on polynomial time bounds and guarantees (as a theorist, I like to see this material), instead adding value by discussing important computational and implemention issues, including ordering heuristics, strategies for solving the KKT system by Newton's method, etc. The book sometimes has an engineer's feel for the proofs, which is good for students but is a bit frustrating to hard-core math types such as myself. There are many instances where the proof is just a proof via an example. This is consistent with the conversational and informal style of the text, and this informality spills over into the mathematics on occasion.
This book has style. As mentioned earlier, the book has a wonderfully appealing conversational style. While the author does not purposely go out of his way to be cute and corny, he succeeds in leaving the reader grinning with his humor. There are some passages that are downright funny, but the style succeeds mostly by default. One section on the issue of modeling the anchoring of truss design problems is called Anchors Away, the subsection on updating factorizations to reduce fill-in is aptly called Shrinking the Bump. And there is the hint of a racy discussion of an application of Konig's Theorem involving boys and girls that the curious reader might enjoy.
Overall, I greatly enjoyed reviewing this book, and I highly recommend the book as a textbook for an advanced undergraduate or master's level course in linear programming, particularly for courses in an engineering environment. In addition, the book also is a good reference book for interior point methods as well as for implementation and computational aspects of linear programming. This is an excellent new book.

Multilevel Theory, Research, and Methods in Organizations: Foundations, Extensions, and New Directions
Manufacturer: Pfeiffer ProductGroup: Book Binding: Hardcover Similar Items:
ASIN: 0787952281 |
Book Description
Organizational science has never been a fully integrated discipline. Traditionally, organizational research has been conducted from three distinct points of view--the organization, the group, and the individual--although it is clear that processes occurring across all levels of an organization affect the behavior of individuals, groups, and organizations as a whole. This fragmentation has encouraged the proliferation of separate disciplines, theories, and approaches. But in this volume, two dozen experts convince readers to consider multilevel analysis in the study of virtually all phenomena that occur within organizations. By illuminating top-down, bottom-up, and A-level processes and effects within an organization, the contributors bridge the gap between macro and micro approaches with a single unified theory.

The Ultimate Foundation of Economic Science: An Essay on Method

Von Mises The Rationalist.......2003-02-21
In "The Ultimate Foundation", von Mises returns to one of his central concerns: the foundation of economic theories. According to von Mises, the principles of economic thought are "a priori." In fact, they are a "subset" of more basic principles of human action. Von Mises called the study of human action "praxiology." According to Mises, the a priori categories "are the mental equipment by dint of which man is able to think and to experience and thus to acquire knowledge." [p. 18.] It is these categories which provide order and regularity to man's understanding. The category of human action is: "Man acts because he is dissatisfied with the state of affairs as it prevails in the absence of his intervention." [p. 3.] Further axioms follow logically from this axiom. [p. 45.] The principles of economics are therefore deductive. On the other hand, the principles of the physical sciences are inductive. The error of positivism is to apply the principles of the physical sciences to economics, where they are not applicable. Economics is closer to mathematics than it is to chemistry.
It's hard to summarize this book. Von Mises deals with a large number of topics in a relatively small number of pages. These include evolution, Marxism, theism, the use of statistics, and methodological individualism. Yet what shines through is von Mises' love of economics and his belief that the teachings of economics - which is to say free enterprise - is the key to increasing man's standard of living and promoting social cooperation.
Interestingly, von Hayek - Mises' best known student -- also returned to methodology in his final book, "The Fatal Conceit." While von Mises remained a rationalist until the end, Hayek drifted toward a more empirical approach to social and economic thought. It would make an interesting study to compare these two works. Joseph Salerno touches on some of these points in his essay "Mises as Social Rationalist" in Herbener, ed., "The Meaning of Ludwig von Mises."

Marketing Research from a Project Based Perspective.......2004-06-29
Rather than focusing on decision support systems or marketing information systems, this book is focused on a project based approach. The authors help you recognize a problem, how to formulate it clearly, present it to decision makers for approval, designing the research to be done, data design and collection methods, they offer sample designs which is very helpful. They then do a fabulous job on data analysis and conclude by showing you how to present a proper research report.
There are several helpful appendices providing statistical values for those calculator based problems, but, really, who doesn't use a spreadsheet or SPSS or some similar package anymore?
There is also a glossary, a subject index, and an author index.
This is a standard text on the subject, and it is terrific.
Expensive but worth every penny!.......2000-08-24
The book sets out to explain how to: Formulate your problem. Determine your research design. Design your collection method and forms. Design your sample and collect the data. Analyse and interpret the data. Prepare your research report.
It is then subdivided into sub sections. I was particularly impressed with the section on ethics, which was so clearly laid out that I used it as a guide when writing a pure ethics paper.
The book is amply supplied with examples and case studies to illustrate the text and make it useful in a more practical sense.
All in all a clear, accessible, well laid out and well indexed textbook.
