This book adds a social psychological component to the analysis of why nations, sections, or states enter into armed conflict. The Disequilibrium, Polarization, and Crisis Model is introduced, drawing from prospect theory, realism, liberalism, and constructivism. Three case studies are included, demonstrating this model and its six process stages

This article provides a non‐mainstream discussion on the value chain concept, which challenges generally believed positions in the area of supply chain management. The author argues that the ultimate consumer is the trigger in the supply chain. The article discusses the concept of value and the value chain, and proposes a modified meaning and interpretation of the value chain model from the point of view of a holistic supply chain context. The author proposes a modified consumer driven value chain diffusion model and an extended bi‐directional value chain diffusion model.

We study the polarization dependence of optical absorption for a modified Haldane model, which exhibits antichiral edge modes in the presence of sample boundaries and has been argued to be realizable in transition metal dichalcogenides or Weyl semimetals. A rich optical phase diagram is unveiled, in which the correlations between perfect circular dichroism, pseudospin andvalley polarization can be tuned independently upon varying the Fermi energy. In particular, perfect circular dichroism and valley polarization are achieved simultaneously. This combination of optical properties suggests some interesting photonic device functionality (e.g., light polarizer) which could be combined with valleytronics applications (e.g., generation of valley currents). ; M.V. acknowledges the Graphene Flagship grant and the Department of Physics of Tohoku University for its hospitality.

Abstract This article examines the diffusion of independent regulatory agencies (IRAs) in Brazil, demonstrating how important domestic factors interplayed with traditional mechanisms of diffusion lead to an expressive process of agencification. Although top-down, bottom-up and horizontal mechanisms played an important role in the Brazilian agencification process, they fail to explain the creation of IRAs in unexpected sectors or the frequent modifications that occurred at subnational levels in a short period of time. To understand how local political actors adapted the regulatory agency model to the Brazilian institutional legacies, field research was conducted, based on bibliographical, documental, and interviews with key political actors. The specificities of Brazilian federalism and the strategic role of the film industry, bureaucrats and politicians in (re)interpreting the agency model helped to boost the diffusion of IRAs in Brazil.
