Determinants of Job-Finding Intentions Among Young Adults from 11 European Countries
No full textIn this study we investigate the impact of individual, parental and social factors on young adults’ job-finding intentions across countries and overall. We test our hypotheses by conducting binary logistic regressions on the basis of an original dataset that comprises responses from more than 5200 young adults and their parents from 11 European countries. Our findings show that individual factors are most decisive in shaping the job-finding intentions of young adults. Most importantly, being enrolled in education does not prevent young adults from lowering their aspirations with respect to anticipated earnings or finding more sophisticated jobs. Social factors, in terms of being socially involved or having more friends in employment, lead to stronger mobility intentions as well as to stronger intentions to improve skills or develop new ones. At the country level, and compared to Italian participants, who go through a longer school-to-work transition, participants from Northern or Central European countries, as well as from the United Kingdom, show weaker mobility intentions. In many of these countries, young adults are also more willing than their Italian counterparts to lower income aspirations, while being less inclined to lower their aspirations in terms of finding more sophisticated jobs. In a last step, we reflect on education as a means of improving professional aspirations and the need to offer adequate on-the-ground services to help young people through the school-to-work transition, especially in Southern European countries.

Unconstrained springback behavior of Al-Mg-Si sheets for different sitting times
No full textIn this work, the springback behavior of the commercial 6022 aluminum alloy in temper aging (T4) is investigated taking into account that the sheets, prior to deformation process, are initially pre-strained and then submitted to various sitting times at room temperature. The unconstrained cylindrical bending test based on the NUMISHEET2002 proceedings as presented by Yoon et al. [Yoon JW, Pourboghtat F, Chung K, Yang DY. Springback prediction for sheet metal forming process using a 3D hybrid membrane/shell method. International journal of Mechanical Sciences 2002;44:2133-53] is selected as validation benchmark. For finite element simulations, the geometry is modeled by solid-shell finite elements using the formulation of Alves de Sousa et al. [Alves de Sousa RJ, Yoon JW, Cardoso RPR, Fontes Valente RA, Gracio JJ. On the use of a reduced enhanced solid-shell (RESS) element for sheet forming simulations. International journal of Plasticity 2007;23:490-515; Alves de Sousa RJ, Cardoso RPR, Fontes Valente RA, Yoon J-W, Natal Jorge RM, Gracio JJ. A new one-point quadrature enhanced assumed strain (EAS) solid-shell element with multiple integration points along thickness: Part I-Geometrically linear applications. International journal for Numerical Methods in Engineering 2005;62:952-77; Alves de Sousa RJ, Cardoso RPR, Fontes Valente RA, Yoon JW, Gracio JJ, Natal Jorge RM. A new one-point quadrature enhanced assumed strain (EAS) solid-shell element with multiple integration points along thickness: Part II-Nonlinear applications. International journal for Numerical Methods in Engineering 2006;67:160-88]. The material behavior is described based on the work of Correia et al. [Correia JPM, Simoes F, Gracio JJ, Barlat F, Ahzi S. A simple hardening rule accounting for time-dependent behavior in Al-Mg-Si alloys. Materials Science Engineering A 2007;456:170-9]. The results of conducted experiments and numerical simulations are compared. It can be concluded about the good agreement between experiments and simulations attesting the effectiveness of the material model utilized to describe the time-dependent hardening behavior.

Thermally Induced Synthesis of Anthracene-, Pyrene- and Naphthalene-Fused Porphyrins
No full textThe synthesis of π-extended porphyrins containing anthracenyl moieties still represents an important challenge. Here, we report on the synthesis of a series of unsubstituted naphthyl-, pyrenyl- and anthracenyl-fused zinc porphyrin derivatives. To this aim, meso-substitued porphyrins are synthesized and the fusion of the PAHs (Polycyclic Aromatic Hydrocarbon) on the β-positions are performed through thermally induced dehydro-aromatization. The fused zinc-porphyrin derivatives are fully characterized and their optical absorption and photoluminescence properties are reported. We also demonstrate that zinc can be removed from the porphyrin core, giving rise to pure C, H, N materials. This work constitutes the first step towards the synthesis of the fully-fused tetra-anthracenylporphyrin
