Instructors in a blended learning format struggle to find an effective balance between face-to-face instruction that is high in fidelity and online instruction that is high in flexibility. This chapter presents three cases where asynchronous video communication was used to help offer students instruction high in fidelity and flexibility. Although the medium for sharing asynchronous video varied between the three cases, findings indicate that video was a useful tool to improve instructor immediacy and/or social presence with a minimum amount of face-to-face instruction. The instructors in all three cases saw asynchronous video communications as an effective way to communicate with students, and the majority of students responded positively to asynchronous video communications.

Whereas attitudes toward risk play an important role in many decisions over the life course, factors that affect those attitudes are not fully understood. Using longitudinal survey data collected in Mexico before and during the Mexican war on drugs, we investigate how risk attitudes change with variation in insecurity and uncertainty brought on by unprecedented changes in local-area violent crime. Exploiting the fact that the timing, virulence, and spatial distribution of changes in violent crime were unanticipated, we establish there is a rise in risk aversion spread across the entire local population as local-area violent crime increases.
