Overcoming performance and convergence issues of discrete transform based modeling of crosslinking classical and reversible deactivated radical polymerizations

Population balances of polymer species in terms 'of discrete transforms with respect to counts of groups lead to tractable first order partial differential equations when ali rate constants are independent of chain length and loop formation is negligible [l]. Average molecular weights in the absence ofgelation are long known to be readily found through integration of an initial value problem. The extension to size distribution prediction is also feasible, but its performance is often lower to the one provided by methods based upon real chain length domain [2]. Moreover, the absence ofagood starting procedure and a higher numerical sensitivity hás decisively impaired its application to non-linear reversibly deactivated polymerizations, namely NMRP [3].

The economic voter and economic crisis

Theories of economic voting have a long tradition in political science and continue to inspire a large group of scholars. Classical economic voting theory assumes a reward-and-punishment mechanism (Key, 1966). This mechanism implies that incumbents are more likely to stay in power under a good economy, but are cast out under a bad economy (Lewis-Beck and Stegmaier, 2000). The economy has repeatedly been shown to be a major determinant of electoral behavior (see especially the recent book by Duch and Stevenson, 2008), but the current economic crisis seems to provide a marked illustration of how the economy affects voting. In recent elections across the Western industrialized world, most ruling coalitions lost their majority. Opposition parties, on the other hand, whether right wing or left wing, have appeared to benefit from the economic downturn.
