This maximizes collaboration with the perpetrator and strengthens the support network necessary to consolidate control over contested regions. I develop a model of the magnitude and structure of civilian killings in civil wars involving two arme...

The study uses a spatial gravity model with spatial dependence in the bilateral flows between origins and destinations. This is important for policy because it underscores the futility of parochial policy targeting in the presence of spatial spillover. Traditionally, it has been assumed that only developments in the origins and destinations affect the magnitude of migration between them. In the...

Over 50% of South African adult women and 30% of adult men are either overweight or obese, and nearly half of all adults are insufficiently active, with major increases in obesity-associated healthcare expenditures since 1980, a high proportion of which are paid by private health insurance. In this paper, we describe the Vitality programme, an incentivized health promotion programme from South ...

The cuttings-sticks problem is the following. We are given a bundle of sticks all having integer lengths. The total sum of their lengths is n(n+1)/2. Can we break the sticks so that the resulting sticks have lengths 1, 2, . . . , n? The problem is known to be NP-hard. We consider an optimization version of the problem which involves cutting the sticks and placing them into boxes. The problem ha...
