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].

Prospects for regulatory convergence under TTIP. Bruegel Policy Contribution 2013/15, October 2013

An ambitious, comprehensive and high-standard trade and investment agreement between the European Union and the United States is feasible, but a key concern is whether the transatlantic trade partners will succeed in creating a meaningful agreement within the tight timeline of the Transatlantic Trade and Investment Partnership (TTIP) negotiations. The target of a ratified pact before a new European Commission takes office in November 2014 is an objective that is likely to conflict with the level of ambition on the substance. Regulatory congruence would require the unilateral and unconditional recognition by the TTIP partners of each other’s standards, procedures and conformity assessment tests. The way forward is to create a ‘living’ (or progressive commitment) agreement on regulatory cooperation with a horizontal template for coherence and conformity assessment and a detailed monitoring mechanism, with implementation starting immediately for a few selected sectors. Regulatory harmonisation under TTIP may not lead to emerging markets automatically upgrading to the higher TTIP standards. Domestic priorities and the high demand from a rising price-sensitive group of consumers will likely result in a dual regulatory regime in emerging markets in the medium-term.

Future of skills in Europe-Convergence or polarisation? CEPS Working Document No. 390, 27 February 2014

In this Working Paper, based on nearly 20 papers produced by the Centre for European Policy Studies, Slovak Governance Institute and the Conference Board Europe, we examine whether the current trends in the areas of education and skills are pushing the European Union, towards convergence or polarisation. We cover a wide range of questions related to this main issue. No easy answers, but several cross-cutting messages emerged from the research. We demonstrated that there is increasing complexity in what a ‘low-skilled’ person is and how well (or poorly) s/he fares in the labour market. There are undoubtedly powerful forces pushing for more polarisation, particularly in the labour market. Our research confirmed that early childhood education plays an important role, and it also appears to be increasingly uncontested as a policy prescription. However, the other frequently emphasised remedy to inequality – less selection in secondary education, particularly later division of children into separate tracks – is more problematic. Its effectiveness depends on the country in question and the target group, while education systems are extremely difficult to shift even on a long-term basis. A different, more-nuanced type of warning to policy-makers is delivered in our research on returns to higher education by field of study, which showed hidden rationality in how students choose their major.
