Book Description
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.

Book Description
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

Book Description
You'll find several books on basic or advanced MySQL performance, but nothing in between. That's because explaining MySQL performance without addressing its complexity is difficult. This practical book bridges the gap by teaching software engineers mid-level MySQL knowledge beyond the fundamentals, but well shy of deep-level internals required by database administrators (DBAs). Daniel Nichter shows you how to apply the best practices and techniques that directly affect MySQL performance. You'll learn how to improve performance by analyzing query execution, indexing for common SQL clauses and table joins, optimizing data access, and understanding the most important MySQL metrics. You'll also discover how replication, transactions, row locking, and the cloud influenceMySQL performance. Understand why query response time is the North Star of MySQL performance Learn query metrics in detail, including aggregation, reporting, and analysis See how to index effectively for common SQL clauses and table joins Explore the most important server metrics and what they reveal about performance Dive into transactions and row locking to gain deep, actionable insight Achieve remarkable MySQL performance at any scale

Book Description
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.
