INTRODUCTION In recent years, admission of critical newborn infants (NBIs) to the neonatal intensive care unit of Hospital Garrahan (HG) has been limited due to the hospitalization of infants younger than 30 days old through spontaneous demand for services. This is probably a multifactorial situation, and one of its causes is a lack of regionalization, which results in an inadequate use of reso...

The recent closure of rural health services in many developed countries has been a natural experiment as health planners strategically adopt regionalized systems of care to combat staggering healthcare system costs. Regionalization is predicated on offering health services in selected discrete locations (‘referral centers’) as opposed to in every local community of reasonable size. Where comple...

Regionalization in the telencephalon results in the formation of functionally and anatomically distinct territories. Cell fate analysis and gene expression studies suggest these subdivisions arise relatively late in development compared with the spinal cord or hindbrain. The mechanisms underlying the commitment of telencephalic cells to specific regional identities have been examined through re...

The regional spatial scale is a vital linkage for the informed extrapolation of results from local to continental scales to address broad-scale environmental problems. Among-region variation in ecosystem state is commonly accounted for by using a regionalization framework, such as an ecoregion classification. Rarely have alternative regionalization frameworks been tested for variables measuring...
