This paper uses a novel source of fine-grained data on IT labor mobility to test the hypothesis that patterns of productivity growth observed after the dot-com bust can be partially explained by spillovers of e-commerce know-how from IT industries to other industries. The analysis treats the timing and geographic concentration of dot-com layoffs as a source of exogenous variation in the effects...

Given the fundamental nature of the IT-productivity link in the IS discipline, the diversity of firm-level data in terms of sources and time periods analyzed in prior research has not been very encouraging. Further, although the IT productivity paradox has been laid to rest on the basis of prior firm-level and industry-level studies, the nature of the relationship in terms of how IT returns evo...

Teluretos vinílicos Z são transformados em cianocupratos vinílicos Z de ordem superior por transmetalação com dimetilou com n-butil(tienil)cianocupratos de lítio. Reação dos cianocupratos vinílicos Z assim obtidos com cloreto de zinco fornece presumivelmente espécies mistas de zinco e cobre que reagem com bromoalquinos levando a eninos e enediinos com retenção da configuração Z da ligação dupla.

Bacteriophage Mu controls an unusual DNA-modification function encoded by the mom gene, which is located in an operon that consists of two overlapping genes. The com gene, located proximal to the 5' end of the common mRNA transcript, encodes a polypeptide of 62 amino acids that is required for translation of mom. Analysis of the derived amino acid sequence reveals that Com contains zinc-binding...

MysterX is an object-oriented Scheme toolkit for building applications from oo-the-shelf COM components. While the COM support in languages such as Haskell and Mercury requires the use of an interface compiler to generate stub code, MysterX uses the reeective capabilities of OLE Automation to make value-marshalling decisions at run-time. MysterX hosts COM components in windows that display Dyna...

Mixed ligand com plexes of bis(phenyldithiocarbazato)nickel(II) with triphenylphosphane and a number of ditertiary phosphanes have been synthesised. The com plexes were characterised on the basis of molar conductance, magnetic moment values, electronic and IR spectra. Out of the five prepared com plexes the mixed ligand com plexes with triphenylphosphane and bis(diphenylphosphino)m ethane are p...
