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.
