Policing Reform: A Historical and Contemporary Analysis provides readers with an in-depth analysis of the past, present, and future of modern American policing. The opening chapter explores social control and the seeds of modern policing, foundations of law enforcement in the U.S., and policing in the early United States. Additional chapters examine the role of American police, the legacy of bigotry within the vocation, and the characteristics of policing as a profession. Students learn about community policing as a possibility for American police reform, problem-oriented policing, and procedural justice and police legitimacy. The book addresses police crime as occupational deviance, excessive use of force, criminal police, police accountability, and police accreditation. The closing chapter addresses the American national police crisis and possible solutions for police reform, including accountability-based policing. Each chapter features chapter objectives, an introduction, questions for discussion, and key terms to support the student learning experience. Providing students with a holistic view of the policing profession and a solutions-focused approach, Policing Reform is a timely and essential resource for courses and programs in policing, law enforcement, and criminal justice.

Pro Data Visualization using R and JavaScript makes the R language approachable, and promotes the idea of data gathering and analysis. You'll see how to use R to interrogate and analyze your data, and then use the D3 JavaScript library to format and display that data in an elegant, informative, and interactive way. You will learn how to gather data effectively, and also how to understand the philosophy and implementation of each type of chart, so as to be able to represent the results visually. With the popularity of the R language, the art and practice of creating data visualizations is no longer the preserve ofmathematicians, statisticians, or cartographers. As technology leaders, we can gather metrics around what we do and use data visualizations to communicate that information. Pro Data Visualization using R and JavaScript combines the power of the R language with the simplicity and familiarity of JavaScript to display clear and informative data visualizations. Gathering and analyzing empirical data is the key to truly understanding anything. We can track operational metrics to quantify the health of our products in production. We can track quality metrics of our projects, and even use our data to identify bad code. Visualizing this data allows anyone to read our analysis and easily get a deep understanding of the story the data tells.

Drawing on news reports, official government press releases and academic research sources, Barker examines a wide array of cases including sexual harassment, sexual abuse, child molestation and police killings, including those of prisoners behind bars.

Performance is a hugely important area of web development. If your site runs slowly, users are going to leave, and the problem only grows as your site gets more popular. Pro JavaScript Performance gives you the tools you need to keep your sites smooth and responsive no matter how many users you have. Best practices are changing or becoming redefined continually because of changes and optimizations at the interpreter level, and differences in system configuration, and network speeds.  This is exacerbated by the quickened release schedule that most browsers have adopted. Just as important as following best practices is the ability to measure your own performance, so that you can adjust as times change, and so that you can note the subtle nuances in your own code and define your own best practices by your own observations. This book gives you the tools to observe and track the performance of your web applications over time from multiple perspectives, so that you are always aware of, and can fix, all aspects of your performance.

While a website is being built, it needs to be tested across multiple browsers and platforms to ensure that the site works for all users, regardless of ability or disability, and this book explains how best to accomplish these tasks.
