BACKGROUND Mental disorders are likely to be elevated in the Libyan population during the post-conflict period. We estimated cases of severe PTSD and depression and related health service requirements using modelling from existing epidemiological data and current recommended mental health service targets in low and middle income countries (LMIC's). METHODS Post-conflict prevalence estimates w...

Defining the relationship between displaced populations and the nation-state is a fraught historical process. The Partition of India in 1947 provides a powerful example. However markedly little attention has been paid to the refugee communities produced (Ansari, 2005). Using the case of the displaced ‘Urdu-speaking minority’ in Bangladesh this article considers what contemporary discourses of i...

The current crisis in Afghanistan has resulted in an influx of Western military personnel, peacekeepers, humanitarian workers, and journalists. At the same time, unprecedented numbers of internally displaced persons and refugees have overwhelmed much of the already fragile infrastructure, setting the stage for outbreaks of infectious diseases among both foreigners and local populations. This re...

The propagation of light in a resonant medium with multiple sublevels depends on the populations of and coherences between theses sublevels. We analyze the case of a J= 1/2-J = l/2 transition with arbitrary ground-state polarization in the limit of a weak probe beam. It is found that transverse components of the ground-state orientation lead to a longitudinal component in the eigenpolarizations...

Emergency physicians (EP) are uniquely suited to provide care in crises as a result of their broad training, ability to work quickly and effectively in high-pressure, austere settings, and their inherent flexibility. While emergency medicine training is helpful to support the needs of crisis-affected and displaced populations, it is not in itself sufficient. In this article we review what an EP...

Analysis of the intensely studied HIV-1 gp120 V3 protein region reveals that the among-population mean site-specific frequency of an amino acid is a measure of its relative marginal fitness. This surprising result may arise if populations are displaced from mutation-selection equilibrium by fluctuating selection and if the probability of fixation of a beneficial amino acid is proportional to it...
