This book provides an account of how and why routine interactions break down and how such situational breakdowns lead to protest violence and other types of surprising social outcomes. It takes a close-up look at the dynamic processes of how situations unfold and compares their role to that of motivations, strategies, and other contextual factors. The book discusses factors that can draw us into violent situations and describes how and why we make uncommon individual and collective decisions. Covering different types of surprise outcomes from protest marches and uprisings turning violent to robbers failing to rob a store at gunpoint, it shows how unfolding situations can override our motivations and strategies and how emotions and culture, as well as rational thinking, still play a part in these events. The first chapters study protest violence in Germany and the United States from 1960 until 2010, taking a detailed look at what happens between the start of a protest and the eruption of violence or its peaceful conclusion. They compare the impact of such dynamics to the role of police strategies and culture, protesters’ claims and violent motivations, the black bloc and agents provocateurs. The analysis shows how violence is triggered, what determines its intensity, and which measures can avoid its outbreak. The book explores whether we find similar situational patterns leading to surprising outcomes in other types of small- and large-scale events: uprisings turning violent, such as Ferguson in 2014 and Baltimore in 2015, and failed armed store robberies.

We frequently speak of certain things or phenomena being built out of or based in others. This soda can is made of molecules, which are in turn made of atoms, which are in turn made of subatomic particles. The behavior of a crowd is based in the behaviors of and interactions between individual people—it behaves as it does in virtue of the individual behaviors and interactions. Making Things Up concerns the family of relations that such talk appeals to, which Karen Bennett calls “building relations.” Grounding is one currently popular such relation; so too are composition, property realization, and—controversially—causation. Building relations connect more fundamental things (like atoms) to less fundamental things (like soda cans). But what are we even talking about when we say that something is more fundamental than something else? This book illuminates the ideas of building and fundamentality, as they are deployed in metaphysics and elsewhere in philosophy. Bennett paints a picture of a hierarchically structured world, and makes good sense of otherwise somewhat cryptic talk of “in virtue of” and fundamentality.

The golden age of road demand modeling began in the 1950s and flourished in the 1960s in the face of major road construction needs. These macro models, as well as the econometrics and the data to be processed, were provided mainly by engineers. A division of tasks can be observed between the engineers in charge of estimating the flows within the network and the transport economists in charge of managing these flows once they are on the road network. Yet the inability to explain their decision-making processes and individual drives gave some room to economists to introduce economic analysis, so as to better understand individual or collective decisions between transport alternatives. Economists, in particular Daniel McFadden, began to offer methods to improve the measure of utility linked to transport and to inform the engineering approach. This paper explores the challenges to the boundaries between economics and engineering in road demand analysis.

Kinetic and optical behaviors of Cibacron™ Yellow R, Scarlet 2GE, and Blue TRE are studied individually and in mixtures. In mixtures, these dyes deviate from their individual behaviors. A method for determining these deviations and for correlating the optical and kinetic deviations is demonstrated. This method is valuable because it allows the kinetic behavior of dyes in mixtures to be characterized from simple optical measurements.
