A new large scale laboratory: The LEDA research centre (Laboratory of Earthquake engineering and Dynamic Analysis)
2017
Recently, the field of earthquake engineering experienced substantial enhancements due to numerous results of experimental and theoretical researches. Modern technical codes recognized the last advances in this field and provided new solutions for the structural assessment and design of buildings. However, the need for large scale testing is still taking several open questions, especially for the design of civil infrastructures, and experimental activity on full scale specimens has become necessary. This paper presents the main testing facilities of a new research centre, namely the Laboratory of Earthquake engineering and Dynamic Analysis (LEDA) of the University of Enna “Kore”. In particu…
Photophysical Properties of Charged Cyclometalated Ir(III) Complexes: A Joint Theoretical and Experimental Study
2011
The photophysical properties of a series of charged biscyclometalated [Ir(ppy)(2)(N boolean AND N)](1+) complexes, where ppyH is 2-phenylpyridine and N boolean AND N is 2,2'-bipyridine (bpy), 6-phenyl-2,2'-bipyridine (pbpy), and 6,6'-dipheny1-2,2'-bipyridine (dpbpy) for complexes 1, 2, and 3, respectively, have been investigated in detail. The photoluminescence performance in solution decreases from 1 to 3 upon attachment of phenyl groups to the ancillary ligand. The absorption spectra recorded over time suggest that complex 3 is less stable compared to complexes 1 and 2 likely due to a nucleophilic-assisted ancillary ligand-exchange reaction. To clarify this behavior, the temperature depen…
EMU Enlargement, Stabilization Cost and Automatic Stabilizers
2008
We use a new approach to assess long-term fiscal developments. By analyzing the time-varying behaviour of the two components of government spendingandrevenue–responsivenessandpersistence–, a feature not captured by automatic stabilisers, we are able to infer about the sources of fiscal deterioration (improvement). Drawing on quarterly data, we estimate recursively these components within a system of government revenue and spending equations using a Three-Stage Least Squaremethod for eight EuropeanUnion countries plus the US. The results suggest that significant changes in the fiscal stance (including those related to the current crisis) are reflected in the estimates of persistence and resp…
Are the New EU Countries Ready for the EURO? A Comparison of Costs and Benefits
2006
This paper examines the main macroeconomic determinants of costs and benefits of adopting the euro for the new EU member countries, and compares them to those of the older members. We show that these cost and benefit factors exhibit substantial variability across the countries considered. Our findings suggest that, in terms of price stability, the position of the new members is overall better than some EMU countries, such as Portugal and Greece. At the same time, we identify countries (such as Slovenia, Cyprus, and Hungary) whose business cycle is already well synchronized with EMU's, but also countries (such as Latvia and Estonia) with lower synchronization, and countries (such as Romania,…
Suppressive Efficacy by a Commercially Available Blue Lens on PPR in 610 Photosensitive Epilepsy Patients
2006
Purpose Photosensitivity can represent a serious problem in epilepsy patients, also because pharmacologic treatment is often ineffective. Nonpharmacologic treatment using blue sunglasses is effective and safe in controlling photosensitivity, but large series of patients have never been studied. Methods This multicenter study was conducted in 12 epilepsy centers in northern, central, southern, and insular Italy. A commercially available lens, named Z1, obtained in a previous trial, was used to test consecutively enrolled pediatric and adult epilepsy patients with photosensitivity. Only type 4 photosensitivity (photoparoxysmal response, PPR) was considered in the study. A standardized method …
Unveiling the strong interaction among hadrons at the LHC
2020
One of the key challenges for nuclear physics today is to understand from first principles the effective interaction between hadrons with different quark content. First successes have been achieved using techniques that solve the dynamics of quarks and gluons on discrete space-time lattices1,2. Experimentally, the dynamics of the strong interaction have been studied by scattering hadrons off each other. Such scattering experiments are difficult or impossible for unstable hadrons3–6 and so high-quality measurements exist only for hadrons containing up and down quarks7. Here we demonstrate that measuring correlations in the momentum space between hadron pairs8–12 produced in ultrarelativistic…
Innovation and networks in rural areas. An analysis from European innovative projects
2014
Abstract Innovation is a central factor for the development of rural areas, both in terms of diversification and increased competitiveness, also related to new structures of governance. The creation, adoption or adaptation of innovations is particularly complex, requiring the right combination of local knowledge (often tacit and implicit) with expert knowledge (often more explicit and formalised), as well as the support of extensive networks. This paper analyses a number of innovation projects in several European rural areas, through the data collected via in-depth interviews. It examines the projects' contributions and the role played by stakeholders in each stage of the projects. On the o…
Complementarities in innovation strategy: do intangibles play a role in enhancing firm performance?
2017
This article assesses the role of investments in intangible capital and their potential complementarities as a way to improve firm productivity. We focus on the three intangible resources that, according to the literature, have the greatest strategic importance: research and development (R & D), advertising, and human capital. To test our hypotheses, we use a large sample of Spanish manufacturing firms and consider estimates of total factor productivity through a generalized method of moments approach. Our results show evidence of complementarities between R & D and advertising investments and between advertising and human capital. However, they are not conclusive in the case of R & D and h…
Export markets: substitutes, complements, or independent?
2020
Using a large sample of export transactions in Spain over the period 2010–2017, we explore whether firms treat export markets as substitutes, complements, or independent. We find that an exogenous ...
The monitoring role of female directors over accounting quality
2017
Recent research in accounting suggests female directors exert more stringent monitoring over the financial reporting process than their male counterparts. However, an emerging literature in finance and economics provides mixed findings and questions whether females in leadership roles significantly differ from their male counterparts. Building on this literature, we re-examine the link between the presence of female directors, gender biases, and financial statements quality. Using a large sample of UK firms we find that a larger percentage of women among independent directors is significantly associated with lower earnings management practices. However, we show that this relation disappears…
