Differentiated integration in the european union: many concepts, sparse theory, few data

Abstract: Differentiated integration has been the subject of political discussion and academic thought for a long time. It has also become an important feature of European integration since the 1990s. By contrast, it is astonishing how poor our research and knowledge about the phenomenon is. Whereas there is an abundance of conceptual work and some normative analysis, positive theories on the causes or effects of differentiated integration are rare. Empirical analysis has concentrated on a few important cases of treaty law (such as EMU and Schengen) while there is no systematic knowledge about differentiated integration in secondary law. The aim of this article is therefore twofold: to review the existing typological and theory-oriented research and to outline a research agenda striving for systematic empirical and explanatory knowledge.

Fluorescent conjugated polymer nanoparticles by polymerization in miniemulsion.

Abstract: Highly fluorescent conjugated polymer nanoparticles were prepared directly by polymerization in aqueous miniemulsion, employing Glaser coupling polymerization as a suitable step-growth reaction. A 4,4′-dinonyl-2,2′-bipyridine-modified catalyst was found to be suited for the polymerization in the aqueous heterophase system. Nanoparticles of poly(arylene diethynylenes) (arylene = 2,5-dialkyoxy phenylenes and 9,9′-dihexyl fluorene) with molecular weights in the range of Mn 104 to 105 g mol−1 and with sizes of ≤30 nm, as observed by TEM, result. N,N′-Di(4-ethynylphenyl)-1,7-di[4-(1,1,3,3-tetramethylbutyl)phenoxy]perylene-3,4:9,10-tetracarboxdiimide or 2,7-diethynylfluorenone was converted completely during the heterophase polymerization to afford colloidally stable nanoparticles of poly(arylene diethynylenes) with 0.1−2 mol % covalently incorporated perylene dye and 2−9 mol % of covalently incorporated fluorenone dye, respectively. Fluorescence spectroscopy of the aqueous dispersions reveals an efficient ener...

Does government ideology influence deregulation of product markets? Empirical evidence from OECD countries

Abstract: This paper examines how government ideology has influenced deregulation of product markets in OECD countries. I analyze a dataset of non-manufacturing regulation indicators covering energy, transport and communication industries in 21 OECD countries over the 1980–2003 period and employ two different indices of government ideology. The results suggest that government ideology has had a strong influence on the deregulation process: market-oriented governments promoted the deregulation of the energy, transport and communication industries. This finding identifies remarkable differences between leftist and rightwing governments concerning the role of government in the economy and basic elements of political order.
