Winner of the 2020 Robert E. Park Award for Best Book from the Community and Urban Sociology Section of the American Sociological Association From a dive bar in New Orleans to a leafy residential street in Minneapolis, many establishments and homes in cities across the nation share a troubling and largely invisible past: they were once sites of industrial manufacturers, such as plastics factories or machine shops, that likely left behind carcinogens and other hazardous industrial byproducts. In Sites Unseen, sociologists Scott Frickel and James Elliott uncover the hidden histories of these sites to show how they are regularly produced and reincorporated into urban landscapes with limited or no regulatory oversight. By revealing this legacy of our industrial past, Sites Unseen spotlights how city-making has become an ongoing process of social and environmental transformation and risk containment. To demonstrate these dynamics, Frickel and Elliott investigate four very different cities—New Orleans, Minneapolis, Philadelphia, and Portland, Oregon. Using original data assembled and mapped for thousands of former manufacturers’ locations dating back to the 1950s, they find that more than 90 percent of such sites have now been converted to urban amenities such as parks, homes, and storefronts with almost no environmental review. And because manufacturers tend to open plants on new, non-industrial lots rather than on lots previously occupied by other manufacturers, associated hazards continue to spread relatively unabated. As they do, residential turnover driven by gentrification and the rising costs of urban living further obscure these sites from residents and regulatory agencies alike. Frickel and Elliott show that these hidden processes have serious consequences for city-dwellers. While minority and working class neighborhoods are still more likely to attract hazardous manufacturers, rapid turnover in cities means that whites and middle-income groups also face increased risk. Since government agencies prioritize managing polluted sites that are highly visible or politically expedient, many former manufacturing sites that now have other uses remain invisible. To address these oversights, the authors advocate creating new municipal databases that identify previously undocumented manufacturing sites as potential environmental hazards. They also suggest that legislation limiting urban sprawl might reduce the flow of hazardous materials beyond certain boundaries. A wide-ranging synthesis of urban and environmental scholarship, Sites Unseen shows that creating sustainable cities requires deep engagement with industrial history as well as with the social and regulatory processes that continue to remake urban areas through time.

Want your web site to display more quickly? This book presents 14 specific rules that will cut 25% to 50% off response time when users request a page. Author Steve Souders, in his job as Chief Performance Yahoo!, collected these best practices while optimizing some of the most-visited pages on the Web. Even sites that had already been highly optimized, such as Yahoo! Search and the Yahoo! Front Page, were able to benefit from these surprisingly simple performance guidelines. The rules in High Performance Web Sites explain how you can optimize the performance of the Ajax, CSS, JavaScript, Flash, and images that you've already built into your site -- adjustments that are critical for any rich web application. Other sources of information pay a lot of attention to tuning web servers, databases, and hardware, but the bulk of display time is taken up on the browser side and by the communication between server and browser. High Performance Web Sites covers every aspect of that process. Each performance rule is supported by specific examples, and code snippets are available on the book's companion web site. The rules include how to: Make Fewer HTTP Requests Use a Content Delivery Network Add an Expires Header Gzip Components Put Stylesheets at the Top Put Scripts at the Bottom Avoid CSS Expressions Make JavaScript and CSS External Reduce DNS Lookups Minify JavaScript Avoid Redirects Remove Duplicates Scripts Configure ETags Make Ajax Cacheable If you're building pages for high traffic destinations and want to optimize the experience of users visiting your site, this book is indispensable. "If everyone would implement just 20% of Steve's guidelines, the Web would be adramatically better place. Between this book and Steve's YSlow extension, there's reallyno excuse for having a sluggish web site anymore." -Joe Hewitt, Developer of Firebug debugger and Mozilla's DOM Inspector "Steve Souders has done a fantastic job of distilling a massive, semi-arcane art down to a set of concise, actionable, pragmatic engineering steps that will change the world of web performance." -Eric Lawrence, Developer of the Fiddler Web Debugger, Microsoft Corporation

An advanced text for those with at least basic understanding of environmental investigation, cleanup, regulations, decision making, and policy development, Accelerating Cleanup at Toxic Waste Sites addresses the "human" side of the environmental industry and why it is perhaps one of the most important considerations for successful accelerated cleanup. This book takes the next step by providing managers, project teams, and other professionals with approaches that bring techniques, regulations, strategies, and people together into one comprehensive package that works.
Performance is critical to the success of any web site, and yet today's web applications push browsers to their limits with increasing amounts of rich content and heavy use of Ajax. In this book, Steve Souders, web performance evangelist at Google and former Chief Performance Yahoo!, provides valuable techniques to help you optimize your site's performance. Souders' previous book, the bestselling High Performance Web Sites, shocked the web development world by revealing that 80% of the time it takes for a web page to load is on the client side. In Even Faster Web Sites, Souders and eight expert contributors provide best practices and pragmatic advice for improving your site's performance in three critical categories: JavaScript—Get advice for understanding Ajax performance, writing efficient JavaScript, creating responsive applications, loading scripts without blocking other components, and more. Network—Learn to share resources across multiple domains, reduce image size without loss of quality, and use chunked encoding to render pages faster. Browser—Discover alternatives to iframes, how to simplify CSS selectors, and other techniques. Speed is essential for today's rich media web sites and Web 2.0 applications. With this book, you'll learn how to shave precious seconds off your sites' load times and make them respond even faster. This book contains six guest chapters contributed by Dion Almaer, Doug Crockford, Ben Galbraith, Tony Gentilcore, Dylan Schiemann, Stoyan Stefanov, Nicole Sullivan, and Nicholas C. Zakas.
An Expert Guide to Software Performance Optimization From mobile and cloud apps to video games to driverless vehicle control, more and more software is time-constrained: It must deliver reliable results seamlessly, consistently, and virtually instantaneously. If it doesn't, customers are unhappy--and sometimes lives are put at risk. When complex software underperforms or fails, software engineers need to identify and address the root causes. This is difficult and, historically, few tools have been available to help. In Understanding Software Dynamics, performance expert Richard L. Sites tackles the problem head on, offering expert methods and advanced tools for understanding complex, time-constrained software dynamics, improving reliability and troubleshooting challenging performance problems. Sites draws on several decades of experience pioneering software performance optimization, as well as extensive experience teaching graduate-level developers. He introduces principles and techniques for use in any environment, from embedded devices to datacenters, illuminating them with examples based on x86 or ARM processors running Linux and linked by Ethernet. He also guides readers through building and applying a powerful, new, extremely low-overhead open-source software tool, KUtrace, to precisely trace executions on every CPU core. Using insights gleaned from this tool, readers can apply nuanced solutions--not merely brute-force techniques such as turning off caches or cores. Measure and address issues associated with CPUs, memory, disk/SSD, networks, and their interactions Fix programs that are always too slow, and those that sometimes lag for no apparent reason Design useful observability, logging, and time-stamping capabilities into your code Reason more effectively about performance data to see why reality differs from expectations Identify problems such as excess execution, slow instruction execution, waiting for resources, and software locks Understanding Software Dynamics will be valuable to experienced software professionals, including application and OS developers, hardware and system architects, real-time system designers, and game developers, as well as advanced students.
