Sources of productivity spillovers: panel data evidence from China

This paper assesses sources of productivity spillovers in China\u27s electric and electronic manufacturing industry using a rich panel data-set of 25,360 firms observed over the period 2004-2007. This industry is characterized by its important reliance on technology. In particular, the paper focuses on the role of other firms\u27 productivity as well as productivity shifters in affecting own firm-level total factor productivity. In addition, this paper examines the possible difference between spillovers from foreign-owned units and from units which participate at global markets through exporting in comparison to domestically-owned and non-exporting units. We find evidence of stronger spillovers from exporting firms than from non-exporting firms. This is true for foreign-owned as well as domestic exporters. The strength of the spillover effects differ across subsectors

Mauritiana rhizophorae gen. et sp. nov. (Ascomycetes, Requienellaceae), with a list of terrestrial saprobic mangrove fungi

The new ascomycete genus Mauritiana is described. It is tentatively attributed to the Requienellaceae, but its relation to Passeriniella is also discussed. A list of all terrestrial mangrove fungi described so far is given.link_to_OA_fulltex

Three new species of Massarina associated with terrestrial, non-marine parts of mangroves

Three species of Massarina were collected during investigations into the saprobic fungi occurring on the terrestrial, non-marine parts of mangrove trees in Mauritius. The new species, M. beaurivagea, M. mauritiana and M. rhizophorae are described, illustrated and compared to similar species.link_to_OA_fulltex

Synthesis of Cyclo (L-Trans-(4-Hydroxyprolinyl)-L-Phenylalanine)

The diketopiperazine Cyclo (L-trans-(4-Hydroxyprolinyl)-L-phenylalanine)1 has been synthesized by coupling a  suitably protected form of L-trans-hydroxy proline with L-phenylalanine ethyl ester, deprotection of the amino group followed by an deacetimisation and finally desilylation. This final product has spectral data that agree with the already reported data in literature.Keywords: diketopiperazine, hydroxyproline, phenylalanin
