War Size Distribution: Empirical Regularities Behind Conflicts

This paper analyses the statistical distribution of war sizes. Using a new methodology we find moderate support for a Pareto-type distribution (power law), considering data from different sources (COW and UCDP) and periods. A power law is a plausible model for the size distribution of a pool of all wars and a sample of wars in many years, although the log-normal distribution is a plausible alternative model that we cannot reject. The random growth of conflicts could generate both types of distribution. We study the growth rates of battle deaths and random growth cannot be rejected for most of the distribution, although the results also reveal a clear decreasing pattern; the growth of deaths declines faster if the number of initial deaths is greater.     

To free or not to free (ride): a comparative analysis of the NATO burden-sharing in the Czech Republic and Lithuania

ABSTRACT

The recent rise in the defence budgets among the NATO members reawakens the free-riding dilemma. This article provides an analysis of the defence spending of two new member states, the Czech Republic and Lithuania. Based on the free-riding theory, we explain why some of the new NATO members decide to increase their defence budgets (Lithuania), and others do not (Czech Republic). In contrast to the majority of works which focus either on the US as the biggest spender or on the “old” members of the Alliance, we explain under what circumstances some of the small European states who became new NATO members started to increase their defence budgets even though they do not have to, and the literature suggests that free-riding is easier. In the process, we identify three crucial factors that in?uence the decision-making process in this regard: the level of threat perception, economic situation, and the US pressure.     

Moral Aspects of “Moral Injury”: Analyzing Conceptualizations on the Role of Morality in Military Trauma

In clinical circles, the concept of “moral injury” has rapidly gained traction. Yet, from a moral philosophical point of view the concept is less clear than is suggested. That is, in current conceptualizations of moral injury, trauma’s moral dimension seems to be understood in a rather mechanistic and individualized manner. This article makes a start in developing an adequately founded conceptualization of the role of morality in deployment-related distress. It does so by reviewing and synthesizing insights from different disciplines into morality and trauma. This discussion will lead to three positions: (1) values and norms are by definition characterized by conflict, (2) moral conflict may entail important social dimensions, and (3) moral conflict may lead to altered beliefs about previously held values. These insights provide important steps in further developing conceptions of the role of morality in deployment-related suffering.     

Dynamic evacuation routes for personnel on a naval ship

We propose a dynamic escape route system for emergency evacuation of a naval ship. The system employs signals that adapt to the causative contingency and the crew's physical distribution about the ship. A mixed‐integer nonlinear programming model, with underlying network structure, optimizes the evacuation process. The network's nodes represent compartments, closures (e.g., doors and hatches) and intersections, while arcs represent various types of passageways. The objective function integrates two potentially conflicting factors: average evacuation time and the watertight and airtight integrity of the ship after evacuation. A heuristic solves the model approximately using a sequence of mixed‐integer linear approximating problems. Using data for a Spanish frigate, with standard static routes specified by the ship's designers, computational tests show that the dynamic system can reduce average evacuation times, nearly 23%, and can improve a combined measure of ship integrity by up to 50%. In addition, plausible design changes to the frigate yield further, substantial improvements. Published 2008 Wiley Periodicals, Inc. Naval Research Logistics 2008     

A Criterion for Settling Inconsistencies in Clausewitz’s On War

On War’s unfinished state has been a source of difficulties for interpretation for 180 years. By establishing a hierarchy of revision among the parts, we propose a criterion that can bring any part of On War in line with the most advanced stage of Clausewitz’s thinking. We exemplify the utility, illustrate the underpinnings and appreciate the potential of this criterion. We argue that the criterion offers the prospect of a shared, coherent, fully consistent and faithful rendering of Clausewitz’s theory of war.     

Why Culture Matters: Revisiting the Sino-Indian Border War of 1962

This article examines the nuclear command and control (C²) system implemented in Pakistan since 1998, and discusses its potential consequences for the risk of inadvertent or unauthorised use of nuclear weapons. I argue that troubled civil-military relations and Pakistan's doctrine of ‘asymmetric escalation’ account for the creation of a command and control system with different characteristics during peacetime and military crises. Although the key characteristics of Pakistan's nuclear C² system allow relatively safe nuclear operations during peacetime, operational deployment of nuclear weapons during military standoffs is likely to include only rudimentary protections against inadvertent or unauthorised nuclear release. The implication of this study is that any shift from peacetime to wartime command and control procedures is likely to further destabilise Indo-Pakistani relations during the early stages of a diplomatic or military standoff, and introduce a non-trivial risk of accidental escalation to the nuclear level.     

Inventory models with nonlinear shortage costs and stochastic lead times; applications of shape properties of randomly stopped counting processes

In this article, we study generalizations of some of the inventory models with nonlinear costs considered by Rosling in (Oper. Res. 50 (2002) 797–809). In particular, we extend the study of both the periodic review and the compound renewal demand processes from a constant lead time to a random lead time. We find that the quasiconvexity properties of the cost function (and therefore the existence of optimal (s, S) policies), holds true when the lead time has suitable log‐concavity properties. The results are derived by structural properties of renewal delayed processes stopped at an independent random time and by the study of log‐concavity properties of compound distributions. © 2015 Wiley Periodicals, Inc.

Horizontal Inequalities and Sons of the Soil Conflict in China

Why are large population movements conflict-prone in some regions while they remain peacefully integrated elsewhere? I argue that clashes between ethnically distinct indigenous populations and migrants – i.e. ‘Sons of the Soil (SoS) conflict’ – erupt when there are large socio-economic and political horizontal inequalities between ‘dominant migrants’ and locals. A comparative case study of two Chinese minority regions based on ethnographic fieldwork and population data provides a vivid illustration of the mechanisms linking migration to SoS conflict. With fewer HIs between migrants and locals, Inner Mongolia avoided many of the violent clashes that were commonplace in Qinghai, a province fraught with disparities.
