Verification and Validation for Quality of UML 2. 0 Models
Author: Bhuvan Unhelkar
A practical approach to enhancing quality in software models using UML Version 2.0
"Despite its increasing usage, many companies are not taking the best advantage of UML and, occasionally, individuals have experienced frustration in applying its standards. Perhaps this is because they have not yet read this book!"
-From the Foreword by Prof. Brian Henderson-Sellers
This book presents a practical checklist approach to enhancing the quality of software models created with the Unified Modeling Language (UML) Version 2.0. The foundation for quality is set by the discussion on the nature and creation of UML models. This is followed by a demonstration of how to apply verification and validation checks to these models with three foci: syntactical correctness, semantic meaningfulness, and aesthetic symmetry. The quality work is carried out within three distinct yet related modeling spaces:
* Model of problem space (MOPS)
* Model of solution space (MOSS)
* Model of background space (MOBS)
Readers can then choose a specific quality approach according to their roles in their projects.
Verification and validation checks are also organized according to these three modeling spaces, making it easier for the reader to focus on the appropriate diagrams and quality checks corresponding to their modeling space. In addition, a major element of this publication is the Strengths, Weaknesses, Objectives, and Traps (SWOT) analysis. This analysis is performed on each UML diagram, enabling readers to fully comprehend these diagrams, their advantages and limitations, and the way in which they can be used in practical projects for modeling.
A consistentcase study of the Lucky Insurance System is provided throughout the chapters to illustrate the creation of good quality UML diagrams, followed by application of quality checks to them. With its emphasis on quality in UML-based projects, this book is an essential resource for all quality professionals, including quality analysts, process consultants, quality managers, test designers, and testers.

Economics of Health and Medical Care
Author: Philip Jacobs
This newly updated and expanded edition strikes the necessary balance of population-based health economics and the more traditional. market-oriented approach to health care economics.

Reviewer: Malathi Srinivasan, MD (University of California Davis)
Description: The authors have written a concise, clear primer on healthcare economics. The book develops major themes in descriptive, explanatory, and evaluative economics and can be easily understood by the noneconomist. It highlights the objectives to be learned at the beginning of each chapter, reviews the material, and provides a series of questions at the end of each chapter to reinforce key points.
Purpose: This introductory book provides an economic approach to understanding healthcare issues affecting our population, using scarcity as a driver of healthcare needs. It focuses on how to do economics, and in thinking about healthcare economics in a systematic fashion. This book, now in its fifth edition, is a much-needed update in the instruction of healthcare economics for the noneconomist. It provides physicians and other healthcare providers a straightforward method of framing the complex economic issues surrounding healthcare delivery and healthcare outcomes.
Audience: This is a primer. Thus, the audience includes any noneconomist who is interested in understanding economic principles. As a physician and a health services researcher, I personally found the book useful, and logically laid out. It should be easy to incorporate elements of this book into a curriculum for medical students and residents. The authors did not provide any biographical data, other than their institutional affiliation:two pages on author identification would be useful in subsequent editions. However, these authors are known in the field of healthcare economics and are credible.
Features: The book covers three major domains of healthcare economics: descriptive, explanatory and evaluative methods. Much like the health services research models with input:> process:> output, this framework is recognizable and easy to follow. This book is useful for several reasons. It emphasizes an understanding of the concept for each section without excessive detail. Each chapter follows the classical educational technique of "foretelling, telling, then recapping." Learning objectives are clearly laid out. Questions/exercises at the end of the chapter track with the content of the chapter, and are illustrative. References are relevant. The diagrams are simple and there is minimal use of equations. This lack of mathematics/equations may offend economic purists, but the noneconomist is still able to see the relationships described based on the text description. The economic principles are described with clear examples, and a progressive disclosure method is used to build up increasingly complex models. There is always a tension in these introductory books between breadth and depth. However, for its stated purposes, there are no major shortcomings of this book.
Assessment: This book fills a unique niche as a healthcare economics primer for noneconomists. It is a standard textbook used in many institutions. This book is more readable than other, more technical books in the area, yet it does not oversimplify the material, nor does it talk down to the audience.

The new edition of this text (dates of previous editions are not stated) continues its mission as an introduction that assumes no economics background. With the aim of teaching students how to think about economic problems in a systematic way, Jacobs (public health services, U. of Alberta, Canada) and Rapoport (economics, Mt. Holyoke College, Mass.) divide material into sections on descriptive, explanatory, and evaluative economics; and coverage includes the various tools used in economic analysis and evaluation. Among the new or expanded topics in this edition: the population-based approach, including international comparisons; agency theory and the applications of principal-agent analysis; the consumerism movement and its economic and policy implications; labor markets and health insurance markets; and cost effectiveness, cost utility, and cost-benefit analysis.
