TAKING CARE OF THEIR OWN: THE CAUSES AND CONSEQUENCES OF SOLDIERS IN BUSINESS

This study examines the causes and consequences of involvement in commercial activities by armed forces with regards to coup risk, development and regime transitions. Utilizing an original dataset on military-owned business enterprises, this dissertation examines the links between armed forces control of business enterprises and finds that military controlled enterprises arise out of strategic resource allocation by leaders to minimize coup risk, and that these economic institutions do indeed work to reduce coup risk, though the effect is mediated by the regime type and wealth of a state

Three Risky Decades: A Time for Econophysics?

Our Special Issue we publish at a turning point, which we have not dealt with since World War II. The interconnected long-term global shocks such as the coronavirus pandemic, the war in Ukraine, and catastrophic climate change have imposed significant humanitary, socio-economic, political, and environmental restrictions on the globalization process and all aspects of economic and social life including the existence of individual people. The planet is trapped—the current situation seems to be the prelude to an apocalypse whose long-term effects we will have for decades. Therefore, it urgently requires a concept of the planet's survival to be built—only on this basis can the conditions for its development be created. The Special Issue gives evidence of the state of econophysics before the current situation. Therefore, it can provide excellent econophysics or an inter-and cross-disciplinary starting point of a rational approach to a new era

Mobile Ad-Hoc Networks

Being infrastructure-less and without central administration control, wireless ad-hoc networking is playing a more and more important role in extending the coverage of traditional wireless infrastructure (cellular networks, wireless LAN, etc). This book includes state-of the-art techniques and solutions for wireless ad-hoc networks. It focuses on the following topics in ad-hoc networks: vehicular ad-hoc networks, security and caching, TCP in ad-hoc networks and emerging applications. It is targeted to provide network engineers and researchers with design guidelines for large scale wireless ad hoc networks
