Chapter 1 introduces the background of the Umbrella Movement, a protest movement that took hold in Hong Kong in 2014, and outlines the theoretical principles underlying the analysis of the role of media and communication in the occupation campaign. It explicates how the Umbrella Movement is similar to but also different from the ideal-typical networked social movement and crowd-enabled connective action. It explains why the Umbrella Movement should be seen as a case in which the logic of connective action intervenes into a planned collective action. It also introduces the notion of conditioned contingencies and the conceptualization of an integrated media system.

Choice Matters: How Healthcare Consumers Make Decisions (and Why Clinicians and Managers Should Care) is a timely and thoughtful exploration of the controversial role of consumers in the U.S. healthcare system. In most markets today, consumers have more options and autonomy than ever before. Empowered consumers easily shop around for products and services that better meet their needs, and they widely share their reviews on social media to inform and influence other consumers. Businesses have responded with better experiences and prices to compete for consumers’ business. Though healthcare has lagged behind other industries in this respect, there is a rising tide of interest in consumer choice and empowerment in healthcare markets. However, most healthcare provider organizations, individual doctors, and health insurers are unprepared to consider patients as consumers. The authors draw upon the fields of medicine, marketing, management, psychology, and public policy as they take a substantive, in-depth look at consumer choice and point out its appropriate use, as well as its limitations. This book addresses perplexing issues, such as how healthcare differs from other consumer-driven markets, how consumers make healthcare decisions, and how increased consumer choice in healthcare can not only aid and empower American consumers but also improve the overall healthcare system.

This chapter discusses contemporary debates regarding the use of artificial intelligence as a vehicle for criminal justice reform. It closely examines two general approaches to what has been widely branded as “algorithmic fairness” in criminal law: the development of formal fairness criteria and accuracy measures that illustrate the trade-offs of different algorithmic interventions; and the development of “best practices” and managerialist standards for maintaining a baseline of accuracy, transparency, and validity in these systems. Attempts to render AI-branded tools more accurate by addressing narrow notions of bias miss the deeper methodological and epistemological issues regarding the fairness of these tools. The key question is whether predictive tools reflect and reinforce punitive practices that drive disparate outcomes, and how data regimes interact with the penal ideology to naturalize these practices. The chapter then calls for a radically different understanding of the role and function of the carceral state, as a starting place for re-imagining the role of “AI” as a transformative force in the criminal legal system.
