The empirical relationship between economic diversity and economic stability varies when it is measured at different geographical scales. This paper evaluates the role of geographical scales in assessing this diversity-stability relationship among counties, states, Economic Areas (EAs), metropolitan counties and metropolitan statistical areas (MSAs) in the contiguous U.S. When choosing geograph...

This paper focuses on the dynamic effects under which the regional economic processes are accomplished, breaking them down into two broad types: neighborhood (horizontal) and economywide (vertical) externalities. So, by means of a proposed dynamic space-time empirical model, it is allowed to obtain the vertical and horizontal competition structure within a regional economic system. Co-integrati...

This paper focuses on the dynamic effects under which the regional economic growth processes are accomplished, breaking them down into two broad types: neighborhood and economy-wide effects. By means of a proposed dynamic space-time empirical model, the competition structure within a multi-regional economic system is developed. Co-integration/error correction modeling techniques are used to sup...

introduction spatial studies as the main tools for the detailed study of all tangible and intangible aspects of regions have special ranks among all kinds of planning. the conformity of this organization with physical environment forms the spatial structure of which is usually observed as a distributed and isotropic spatial structure, focus and polar, unbalanced and haphazard, random and balanc...

Neuroanatomical structure appears to be altered in preterm infants, but there has been little insight into the major perinatal risk factors associated with regional cerebral structural alterations. MR images were taken to quantitatively compare regional brain tissue volumes between term and preterm infants and to investigate associations between perinatal risk factors and regional neuroanatomic...

Our research examines how the organisational structure facilitates knowledge sharing within the group. This case study examines a Victorian regional sustainable group using interviews and social network analysis to identify the group's organisational structure and its effect on knowledge sharing between the members. Our findings indicate that while the mixed membership, lack of hierarchy and la...

Understanding factors that influence population connectivity and the spatial distribution of genetic variation is a major goal in molecular ecology. Improvements in the availability of high-resolution geographic data have made it increasingly possible to quantify the effects of landscape features on dispersal and genetic structure. However, most studies examining such landscape effects have bee...

This paper studies the effect of regional spillovers on the rate of finn formation in two major West Gennan industries for the time period from 1989 to 1993. I exploit regional variations in finn fonnation at the county level to identify the effects of historically given industry structure and employment structure on the emergence of new firms. The results are consistent with the existence of l...
