Crossing the boundary

Crossing the boundary

eGovernment is maturing but as the latest academic research and practitioners' experience shows, challenges rather lie in the managerial and political domain. Cross boundary collaboration, therefore, crossing jurisdictional and organisational boundaries is the next step for government. I offer recommendations and insights from around the globe. This working paper is aimed at administrative and ...

The art of boundary crossing

SITE MAP The art of boundary crossing Finally, spring is in the air. The winter has been unusually long and cold and April the usual flop. Now that May's here, we definitely want to see a different picture; more sun, more colors, more fun! Thank God, May makes everything new, or does it? Maybe it takes a little help from us. Why not take that "Spring is in the air" theme literally and see what ...

On Boundary Crossing Probabilities for Diffusion Processes

In this paper we establish a relationship between the asymptotic form of conditional boundary crossing probabilities and first passage time densities for diffusion processes. We show that, under the assumption that the conditional probability that our diffusion (Xs, s ≥ 0) doesn’t cross an upper boundary g(·) prior to time t given that Xt = z behaves as (a+ o(1))(g(t)− z) as z ↑ g(t), there exi...

Boundary crossing in epithelial wound healing.

The processes of wound healing and collective cell migration have been studied for decades. Intensive research has been devoted to understanding the mechanisms involved in wound healing, but the role of cell-substrate interactions is still not thoroughly understood. Here we probe the role of cell-substrate interactions by examining in vitro the healing of monolayers of human corneal epithelial ...
