The radical right in Europe, between slogans and voting behavior. IHS Political Science Series No. 123, July 2011
No full textThe paper analyzes the radical right‘s attitudes toward the EU focusing in particular on the level of congruence between the programmatic statements of the central office and the voting behavior of their MEPs. It shows that although radical right parties represent a source of opposition to the EU, within the EP they express their dissent making use of the rules of the game, voting with the opposition more than the other forces do, but voting almost as much with the majority. The party public office in the EP is inserted in the legislative process and even more collusive with the other parties of both sides of the political spectrum than the Eurosceptical rhetoric and statements of central office makes the public believe
A Recursive-Faulting Model of Distributed Damage in Confined Brittle Materials
No full textWe develop a model of distributed damage in brittle materials deforming in triaxial compression based on the explicit construction of special microstructures obtained by recursive faulting. The model aims to predict the effective or macroscopic behavior of the material from its elastic and fracture properties; and to predict the microstructures underlying the microscopic behavior. The model accounts for the elasticity of the matrix, fault nucleation and the cohesive and frictional behavior of the faults. We analyze the resulting quasistatic boundary value problem and determine the relaxation of the potential energy, which describes the macroscopic material behavior averaged over all possible fine-scale structures. Finally, we present numerical calculations of the dynamic multi-axial compression experiments on sintered aluminum nitride (AlN) of Chen and Ravichandran. The model correctly predicts the general trends regarding the observed damage patterns; and the brittle to-ductile transition resulting under increasing confinement
Sentimenti, emozioni e politica
No full textSolo in tempi relativamente recenti la ricerca storica ha incrinato il monopolio psico-pedagogico determinato dalla considerazione delle emozioni come requisito naturale, per trasformarlo invece in dato culturale, soggetto a modificazioni nel tempo e nella realtà storica di riferimento. Di qui lo sviluppo della cosiddetta History of Emotions come percorso autonomo gestito dagli storici, con l’ampliamento dell’analisi sulla storia dei comportamenti collettivi fino a comprendere i sentimenti e le relazioni amorose, le pratiche sessuali, gli affetti pubblici e privati come tessere di un mosaico composito ma indispensabile per decifrare rotture e persistenze nel costume nazionale, nella specificità dei vari contesti geografici
Firm Dynamics and Employment Protection: Evidence from Sectoral Data
No full textIn this paper we analyse the impact of employment protection legislation (EPL) on firms' entry and exit rates for a large sample of industries of thirteen countries selected from the most recent version of the OECD Structural and Business Statistics Database. Using a differences-in-differences identification strategy, we find that more stringent EPL is associated to lower entry and exit rates, particularly in industries characterized by higher job reallocation intensity. We also find that both collective and individual dismissal regulations reduce firms' entry and exit rates. Interestingly, our results suggest that the negative effects of EPL is stronger in the case of firms between one and nine employees while, in the case of larger ones, results are not clear-cut. An extensive sensitivity analysis confirm the robustness of our findings
And Yet they Co-Move! Public Capital and Productivity in OECD.
No full textIn this paper we add to the debate on the public capital-productivity link by applying very recent
developments in the panel time series literature that take into account cross sectional correlation in non-stationary panels. In particular we evaluate the productive effect of public capital by estimating various production functions on a panel of 21 OECD countries over the period 1975-2002. Our results suggest
that public capital has a positive long run impact on output, with elasticities that range between 0.05-0.15, depending on model specification. These findings are robust to the existence of spillover effects from public capital investments in other countries and to the inclusion of other productivity determinants, like human capital, the stock of patents and R&D capital. Finally, we do not find any important effect of public capital on GDP in the short run: this suggests that public infrastructure investments might not be a powerful countercyclical policy instrument
R&D, INNOVATION AND KNOWLEDGE SPILLOVERS: A REAPPRAISAL OF BOTTAZZI AND PERI (2007) IN THE PRESENCE OF CROSS-SECTIONAL DEPENDENCE
No full textBottazzi and Peri (Economic Journal 2007;117: 486–511) show the existence of a cointegrating relationship
between the domestic stock of knowledge, domestic R&D and the international knowledge stock for a panel
of OECD countries and interpret it as evidence supporting the semi-endogenous versus the endogenous growth
theory. We replicate the baseline specification of their study and we show that main results are robust to the use of
a different estimation strategy (Bai et al.,Journal of Econometrics
2009;149: 82–99) that duly takes into account
cross-sectional correlation: interestingly, in this case we also find a larger role for knowledge spillovers
