Simulating Refugee Movements: Where Would You Go?

The challenge of understanding refugee movements is huge and affects countries worldwide on a daily basis. Yet, in terms of simulation, the challenge appears to have been largely ignored. I argue that we as researchers can, and should, harness our computational skills to better understand and predict refugee movements. I reflect on the computational challenges of modelling refugees, and present...

ζ k−1 − exp ( ζ k ) for k = 2, . . . ,K , and estimate ζ′ instead. Note that this restriction does not impose any a priori assumption on the model. Let Ω denote the following (population-level) parameters: ζ′ (opening), ζc (clicking given open), ζu (unsubscribing given open), φ (transition probabilities), ρ (initial probabilities), β (effect of covariates on the state-dependent probabilities), ...

We prove that the mapping class group of a closed oriented surface of genus at least two does not have Kazhdan’s property (T).

Let's go shopping: a tool for pediatric resident education.

Residency training is designed to allow trainees to develop the clinical skills and the knowledge base necessary to practice their specialty independently.1 Most pediatric residency programs have been hospital-based, usually in tertiary care institutions. Even required primary care continuity experiences are often based within urban hospital clinics. As a result, pediatric residency graduates h...
