Following on from the work of Goldstein and Gronberg, it is argued that under certain conditions, internal economies of scope form the bases for two types of agglomeration economy. These differ from two more familiar types, which are based on internal and external economies of scale. A further two types of agglomeration economy are shown to derive from different forms of external economy. The c...

National identity is an important magnetic force that draws individuals and organizations to co-locate in the same geographic areas in foreign countries, thus providing a fertile socio-economic context for relationship formation and other social exchanges. Whether the focus is on individuals such as Chinese immigrants in Metropolitan cities (Zhou & Logan, 1989) or organizations such as Korean f...

Are the inventor networks of Silicon Valley more densely connected than those of the Boston Route 128 corridor? The evidence remains mostly historical and controversial to date. We develop an analysis of all the patented inventors in both regions since 1975 and find that the networks of Silicon Valley are simultaneously more connected and less robust than those of Boston. Of greatest interest, ...

Foreign investors access local knowledge by co-locating with other foreign direct investment (FDI) firms. However, different aspects of local knowledge can be obtained from different local businesses. Thus, some foreign investors co-locate with FDI firms from the same country of origin, while others co-locate with foreign industry peers. We argue that, relative to industry FDI agglomeration, co...

Combining macromolecular crystallography with in crystallo micro-spectrophotometry yields valuable complementary information on the sample, including the redox states of metal cofactors, the identification of bound ligands and the onset and strength of undesired photochemistry, also known as radiation damage. However, the analysis and processing of the resulting data differs significantly from ...

In the title complex, [CoBr(C(4)H(7)N(2)O(2))(2)(H(2)O)], a crystallo-graphic mirror plane bis-ects the mol-ecule, perpendicular to the glyoximate ligands. The geometry around the cobalt(III) atom is approximately octa-hedral with the four glyoximate N atoms forming the square base. A bromide ion and the O atom of a water mol-ecule occupy the remaining coordination sites. The N-Co-N bite angles...
