Knowledge generation for poverty reduction within donor organizations.
|Abstract||The Millennium Development Goals have placed poverty reduction at the top of donor organisations' list of priorities. Failure to achieve the MDGs will no doubt place the spotlight on their financial commitments to poverty reduction, but effective poverty reduction relies as much on knowledge of poverty and poverty reduction and the kinds of knowledge that emerge from, and inform, the activities of donor organisations. The paper considers this iss ... [truncated at 450 characters in length]|

Heavy tails in last passage percolation
|Abstract||We consider last-passage percolation models in two dimensions, in which the underlying weight distribution has a heavy tail of index $\alpha<2$. We prove scaling laws and asymptotic distributions, both for the passage times and for the shape of optimal paths; these are expressed in terms of a family (indexed by $\alpha$) of ``continuous last-passage percolation'' models in the unit square. In the extreme case $\alpha=0$ (corresponding to a distri ... [truncated at 450 characters in length]|
