The development of distinct regions in the amniote vertebral column results from somite formation and Hox gene expression, with the adult morphology displaying remarkable variation among lineages. Mammalian regionalization is reportedly very conservative or even constrained, but there has been no study investigating vertebral count variation across Amniota as a whole, undermining attempts to un...

Regionalization, or the grouping of objects in space, is a useful tool for organizing, visualizing, and synthesizing the information contained in multivariate spatial data. Landscape pattern indices can be used to quantify the spatial pattern (composition and configuration) of land cover features. Observable patterns can be linked to underlying processes affecting the generation of landscape pa...

BACKGROUND In high-risk births, the availability and concentration of neonatal resources in larger regional hospitals increases the chance of survival. The advantages of regionalization for low-risk deliveries are still unclear, but some studies have suggested that regionalization also is beneficial for low risk deliveries. The aim of the present study was to investigate both the relevance of r...

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...

Understanding the development of the vertebrate brain and in particular that of the neocortex, where high brain functions reside, remains one of the most difficult and exciting tasks in biology. In this review, we discuss recent experimental evidence as well as different possibilities for the intrinsic regionalization of the embryonic dorsal telencephalon, which may be related to the formation ...

Ethnoracial residential segregation is a complex, multiscalar phenomenon with immense moral and economic costs. Modeling the structure and dynamics of segregation is a pressing problem for sociology and urban planning, but existing methods have limitations. In this paper, we develop a suite of methods, grounded in information theory, for studying the spatial structure of segregation. We first a...

Although regionalism is a long-standing feature in international relations only since the 1960s and more emphatically since late 1980s scholars have shown a dedicated interest in the phenomenon. The literature is nonetheless disarticulated. This article takes one step back to take two steps forward. First it clarifies commonly used terms in the field as region, regionalism and regionalization a...
