The procedures and results of a response time analysis study, which was designed to assess the value of police response to a variety of incidents, are summarized. The two primary objectives of this Kansas City, Missouri, study were: (1) analysis of the relationship of response time to the outcomes of on-scene criminal apprehension, witness availability, citizen satisfaction, and the frequency of citizen injuries in connection with crime and noncrime incidents; and (2) the identification of problems and patterns in reporting crime and requesting police assistance. The study design/data collection process continued over a 3-year period. Data were collected by civilian observers, communication tape analysis, and telephone and personal interviewers. Observers accompanied officers in the field to collect data on travel times and on-scene activities, while tape analysts collected dispatch times by timing verbal exchanges recorded on communications unit tape recordings. Victims of crimes and citizens who reported crime and noncrime incidents were interviewed to obtain reporting time data and to identify the problems encountered and patterns followed by those citizens reporting incidents or requesting police services. To analyze the relationships between response time and outcomes, three intervals in response times were considered: citizen reporting, communications dispatching, and police travel time. Variations in these intervals were then analyzed to see how they affected the probability of making an on-scene arrest and contacting a witness on scene, and how they affected recovery from injuries sustained during the commission of crimes. In addition, to see if the length of response time affected citizen satisfaction, police dispatch and travel times were again analyzed, along with other factors (such as citizens' social characteristics, expected response times, and perceptions of how long response took) considered to be possible determinants of citizens' satisfaction. Results indicated that reporting time was longer than either the time taken to dispatch a call or the time taken to travel to a call, and was nearly as long as the combined time taken to dispatch and travel to a call. For a large proportion of the crimes discovered some time after the incident had occurred, response time was found to be unrelated to the probability of making an arrest or locating a witness. For those crimes involving a victim or witness, reporting time was the strongest time determinant of arrest and witness availability. Citizen satisfaction was more closely related to citizens' expectations and perceptions about response time than to actual response time.

This practical book provides a step-by-step approach to testing mission-critical applications for scalability and performance before they're deployed -- a vital topic to which other books devote one chapter, if that. Businesses today live and die by network applications and web services. Because of the increasing complexity of these programs, and the pressure to deploy them quickly, many professionals don't take the time to ensure that they'll perform well and scale effectively. The Art of Application Performance Testing explains the complete life cycle of the testing process, and demonstrates best practices to help you plan, gain approval for, coordinate, and conduct performance tests on your applications. With this book, you'll learn to: Set realistic performance testing goals Implement an effective application performance testing strategy Interpret performance test results Cope with different application technologies and architectures Use automated performance testing tools Test traditional local applications, web-based applications, and web services (SOAs) Recognize and resolves issues that are often overlooked in performance tests Written by a consultant with 30 years of experience in the IT industry and over 12 years experience with performance testing, this easy-to-read book is illustrated with real-world examples and packed with practical advice. The Art of Application Performance Testing thoroughly explains the pitfalls of an inadequate testing strategy and offers you a robust, structured approach for ensuring that your applications perform well and scale effectively when the need arises. "Ian has maintained a vendor-agnostic methodology beautifully in this material. The metrics and graphs, along with background information provided in his case studies, eloquently convey to the reader, 'Methodology above all, tools at your discretion...' Ian's expertise shines through throughout the entire reading experience."-- Matt St. Onge, Enterprise Solution Architect, HCL Technologies America / Teradyne

During the past few years there has been an dramatic upsurge in research and development, implementations of new technologies, and deployments of actual solutions and technologies in the diverse application areas of embedded systems. These areas include automotive electronics, industrial automated systems, and building automation and control. Comprising 48 chapters and the contributions of 74 leading experts from industry and academia, the Embedded Systems Handbook, Second Edition presents a comprehensive view of embedded systems: their design, verification, networking, and applications. The contributors, directly involved in the creation and evolution of the ideas and technologies presented, offer tutorials, research surveys, and technology overviews, exploring new developments, deployments, and trends. To accommodate the tremendous growth in the field, the handbook is now divided into two volumes. New in This Edition: Processors for embedded systems Processor-centric architecture description languages Networked embedded systems in the automotive and industrial automation fields Wireless embedded systems Embedded Systems Design and Verification Volume I of the handbook is divided into three sections. It begins with a brief introduction to embedded systems design and verification. The book then provides a comprehensive overview of embedded processors and various aspects of system-on-chip and FPGA, as well as solutions to design challenges. The final section explores power-aware embedded computing, design issues specific to secure embedded systems, and web services for embedded devices. Networked Embedded Systems Volume II focuses on selected application areas of networked embedded systems. It covers automotive field, industrial automation, building automation, and wireless sensor networks. This volume highlights implementations in fast-evolving areas which have not received proper coverage in other publications. Reflecting the unique functional requirements of different application areas, the contributors discuss inter-node communication aspects in the context of specific applications of networked embedded systems.

This book describes state-of-the-art techniques for designing real-time computer systems. The author shows how to estimate precisely the effect of cache architecture on the execution time of a program, how to dispatch workload on multicore processors to optimize resources, while meeting deadline constraints, and how to use closed-form mathematical approaches to characterize highly variable workloads and their interaction in a networked environment. Readers will learn how to deal with unpredictable timing behaviors of computer systems on different levels of system granularity and abstraction.

From 1976 to the beginning of the millennium—covering the quarter-century life span of this book and its predecessor—something remarkable has happened to market response research: it has become practice. Academics who teach in professional fields, like we do, dream of such things. Imagine the satisfaction of knowing that your work has been incorporated into the decision-making routine of brand managers, that category management relies on techniques you developed, that marketing management believes in something you struggled to establish in their minds. It’s not just us that we are talking about. This pride must be shared by all of the researchers who pioneered the simple concept that the determinants of sales could be found if someone just looked for them. Of course, economists had always studied demand. But the project of extending demand analysis would fall to marketing researchers, now called marketing scientists for good reason, who saw that in reality the marketing mix was more than price; it was advertising, sales force effort, distribution, promotion, and every other decision variable that potentially affected sales. The bibliography of this book supports the notion that the academic research in marketing led the way. The journey was difficult, sometimes halting, but ultimately market response research advanced and then insinuated itself into the fabric of modern management.
