Are interorganizational network ties “placeless” or “placed”? The study of organizations, particularly the study of interorganizational network ties, has reemerged in urban sociology, yet the urban literature on place and the organizations literatures on organizational network activity are not fully integrated. This article bridges these theories through an investigation of the social and spati...

We present an analytical study of the dynamical local-field factors associated with the response of a homogeneous two-dimensional interacting electron liquid as functions of momentum, frequency, and density. We derive sum rules that constrain their asymptotic forms ~in momentum and frequency! for both the spinsymmetric and spin-antisymmetric cases. Parametrized expressions for the local-field f...

We explore the local electronic signatures of molecular adsorption at coordinatively unsaturated binding sites in the metal-organic framework Mg-MOF-74 using X-ray spectroscopy and first-principles calculations. In situ measurements at the Mg K-edge reveal distinct pre-edge absorption features associated with the unique, open coordination of the Mg sites which are suppressed upon adsorption of ...

Local economic development (LED) should be everybody’s business, including local residents, local business people and government. LED is globally, but especially in developing countries, seen as the solution to improved quality of life, unemployment, poverty and inequality. LED is a relatively new field of research and policy formulation, planning processes and implementation plans are still ev...

A non-contradictible axiomatic theory is constructed under the local reversibility of the metric triangle inequality. The obtained notion includes the metric spaces as particular cases and the generated metric topology is T$_{1}$-separated and generally, non-Hausdorff.

On the basis of spectral-expansion Green s function theory, we theoretically describe the fundamental harmonic (FH) and second harmonic (SH) local fields at nanorough surfaces of silver and gold. The numerical simulation of these fields in the model of random planar composites has shown that the SH local-field intensity possesses power-law (scaling) distribution for a wide range of system and e...
