Financing prosperity in the next century - The changing world of banking: Setting the regulatory agenda

The authors of this brief propose a series of reforms aimed at making bank regulations compatible with the changing financial system. They present evidence to support their contention that change in the market for financial services has reduced the importance of depositories as they have traditionally operated. A dramatic increase in nonbank competition has contributed to a substantial shrinkage in the proportion of total financial assets held by depository institutions. The authors assert that any reforms should take into account the dynamic nature of the financial marketplace. Effective reforms tackling bank regulation must pass a two-part test: they must protect the payments and credit mechanisms in order to promote systemic stability, and they must promote competition within the financial services industry

Dispersal connectivity and reserve selection for marine conservation

Although larval dispersal is crucial for the persistence of most marine populations, dispersal connectivity between sites is rarely considered in designing marine protected area networks. In particular the role of structural characteristics (known as topology) for the network of larval dispersal routes in the conservation of metapopulations has not been addressed. To determine reserve site configurations that provide highest persistence values with respect to their connectivity characteristics, we model nine connectivity topological models derived from graph theory in a demographic metapopulation model. We identify reserve site configurations that provide the highest persistence values for each of the metapopulation connectivity models. Except for the minimally connected and fully connected populations, we observed two general 'rules of thumb' for optimising the mean life time for all topological models: firstly place the majority of reserves, so that they are neighbours of each other, on the sites where the number of connections between the populations is highest (hub), secondly when the reserves have occupied the majority of the vertices in the hub, then select another area of high connectivity and repeat. If there are no suitable hubs remaining then distribute the remaining reserves to isolated locations optimising contact with non-reserved sites. (C) 2011 Elsevier B.V. All rights reserved
