On labeling the vertices of products of complete graphs with distance constraints

Variations of Hale's channel assignment problem, the L(j, k)‐labeling problem and the radio labeling problem require the assignment of integers to the vertices of a graph G subject to various distance constraints. The λ_j,k‐number of G and the radio number of G are respectively the minimum span among all L(j, k)‐labelings, and the minimum span plus 1 of all radio labelings of G (defined in the Introduction). In this paper, we establish the λ_j,k‐number of ∏ K for pairwise relatively prime integers t₁ < t₂ < … < t_q, t₁ ≥ 2. We also show the existence of an infinite class of graphs G with radio number |V(G)| for any diameter d(G). © 2003 Wiley Periodicals, Inc. Naval Research Logistics, 2005

Attrition through a partially coordinated area defense

An area defense consists of several groups that act independently, i.e., do not communicate with each other. Each group has a fixed number of defenders and a controller that allocates these defenders optimally against the individual attackers comprising an attack. We analyze the effectiveness of this partially coordinated defense against a simultaneous attack of known size in which all attackers are considered to be equally lethal. © 2004 Wiley Periodicals, Inc.

Stochastic modeling for computational warranty analysis

We examine two key stochastic processes of interest for warranty modeling: (1) remaining total warranty coverage time exposure and (2) warranty load (total items under warranty at time t). Integral equations suitable for numerical computation are developed to yield probability law for these warranty measures. These two warranty measures permit warranty managers to better understand time‐dependent warranty behavior, and thus better manage warranty cash reserves. © 2005 Wiley Periodicals, Inc.

PEACEKEEPERS AS PERPETRATORS OF ABUSE

I am afraid there is clear evidence that acts of gross misconduct have taken place. This is a shameful thing for the United Nations to have to say, and I am absolutely outraged by it.

—Kofi Annan, United Nations Secretary-General

Despite promulgating a comprehensive set of guidelines to deter UN personnel from committing acts of sexual misconduct, allegations of sexual exploitation and abuse have become widespread within United Nations peacekeeping missions. The policy of zero-tolerance for peacekeeper misconduct has not been matched by strong disciplinary measures, and crimes are often ignored and rarely punished: absentee fathers, rapists and murderers simply disappear back in their home countries. In countries where women and children rarely have the same economic resources, political rights and authority or control over their environment—or their bodies—they easily become prey for those in perceived positions of power and authority. By failing to hold those responsible to account, the UN may in fact be fuelling even greater discrimination and violence against women and children. In order to ensure those who are mandated to protect to do not become perpetrators of abuse, the UN must take a stronger stand against those who commit acts of sexual misconduct, and must ensure that victims see that their abuser is brought to justice and that reparation is offered. A recent report submitted by the Secretary-General's Special Envoy on Sexual Exploitation and Sexual Abuse makes a comprehensive set of recommendations to prevent, detect, and respond to these allegations. The aim of this essay is to highlight some of the main points of the Special Envoy's report, and to examine the practical challenges the UN and troop/police contributing countries will face when attempting to implement these recommendations.     

External security determinants of Greek military expenditure: An empirical investigation using Neural networks

Greece has regularly ranked as the country with the highest defence burden in NATO and the European Union. Over the past decades she has allocated an averatge 6% of GDP to defence yearly. This study using neural networks examines the external security determinants of Greek military expenditure in the context of the ongoing Greek‐Turkish conflict.
