An innovative moment resisting steel connection: optimal design formulations, practical applications and experimental tests
2023
This thesis concerns the study of an innovative moment resisting connection device to be adopted in the so-called moment resisting steel frames. Following previous seismic events, such as Northridge in 1994, many steel structures characterized by welded connections between beams and columns experienced extended damages and diffused brittle failures, making the facilities unserviceable and economically disadvantageous to repair. The answers to this problem is represented by a large number of studies, where several proposals for different devices, as well as special technical solutions, are available. However, the main idea developed among all the proposals is represented by the identificatio…

The Effect of Public Education Expenditure on Shadow Economy: A Cross-Country Analysis
2015
AbstractThis paper empirically examines whether devoting more resources to education can reduce the size of the shadow economy on a cross-section of countries. The findings show a negative relationship between public education expenditure and the size of the shadow economy, which is robust to the inclusion of different proxies for the control variables, a large set of policy variables, regional differences and endogeneity. The findings also emphasize the role of education, suggesting that public policies devoted to higher education level imply a decreasing effect on the shadow economy.
Populism and Immigration: (Re)Inventing Identities Through Language
2022
Populism is one of the hottest topics of the moment and immigration is a fundamental lens for understanding its success, although not the only one. Starting from this assumption, this chapter aims to specify how language can be used as a strategic resource to empower populist platforms. The analysis contributes to the existing analysis by clarifying that language is intrinsically evaluative: the choice of the use of words and the linguistic strategies implemented by any political actor cannot be seen as neutral. Hence, we argue that (radical right) populists do not make a pathological use of language per se. The populist linguistic strategies belong to a physiological dimension, in the sens…
Citizens, citizenship and European Union: an open bet? The culture of legality
2016
Although the meanings of citizenship, active citizenship and organized crime are still open to debate, we try to show the evaluation of the culture of legality and the investments in social, economic and cultural programs for youth as a major defense for such a capillary phenomenon. There is also general agreement that EU programs for endorsing citizenship and active citizenship represent an effective tool for creating transnational networks of young people committed to EU values. Thus, they perceive the culture of legality as the best form of protection against arbitrary violence with references not only to a developed (and eventually harmonized) system of legal sanctions, but also to the …
Comparison among three boundary element methods for torsion problems: CPM, CVBEM, LEM
2011
This paper provides solutions for De Saint-Venant torsion problem on a beam with arbitrary and uniform cross-section. In particular three methods framed into complex analysis have been considered: Complex Polynomial Method (CPM), Complex Variable Boundary Element Method (CVBEM) and Line Element-less Method (LEM), recently proposed. CPM involves the expansion of a complex potential in Taylor series, computing the unknown coefficients by means of collocation points on the boundary. CVBEM takes advantage of Cauchy’s integral formula that returns the solution of Laplace equation when mixed boundary conditions on both real and imaginary parts of the complex potential are known. LEM introduces th…
Measure of a limestone weathering degree using Laser Scanner.
2013
The weathering degree of the building materials and natural stones is generally quantified as the decrement of some mechanical features that can be measured experimentally by means of compressive tests or point load tests in the laboratory or Schmidt hammer tests carried out in situ. Such destructive or damaging tests are unacceptable in case of cultural heritage since even small amounts of damage must be avoided. This work shows a correlation between Schmidt hammer rebound values and the reflectivity that is detected by means of terrestrial scanner laser; therefore it allows assessing the weathering degree of buildings or stones in situ. The results demonstrate that such an investigation c…
Ultra-fast-prototyping of PMMA structures for micro-engineering applications: Choosing the right material
2017
Machining of poly(methyl methacrylate) (PMMA) by laser has been extensively studied in engineering research for several applications including microfluidic manufacturing and rapid prototyping. However, very few investigations have taken into consideration the wide range of physico-chemical characteristics of commercially available PMMA that can often affect the quality of the laser-machined structures. These characteristics are often ignored, with many manufacturing publications focusing on a single source of PMMA. To understand the different bonding strengths and laser-cut qualities in the context of our ultra-fast prototyping technique, four types of PMMA have been examined. Molecular wei…
LEONARDO SCIASCIA E PRIMO LEVI. APPUNTI SU ETICA E SCIENZA
2020
Nel secondo Novecento la minaccia nucleare angoscia l’intera umanità riaccendendo il dibattito sulla libertà della scienza e sull’intricato rapporto che questa intrattiene con il potere. Sciascia e Levi offrono nei loro scritti visioni della scienza assai diverse, talora opposte: Sciascia rivendica la superiorità della cultura umanistica (e letteraria) rispetto alla cultura scientifica, confermando la frattura denunciata da C. P. Snow che il chimico Levi considerava, invece, innaturale. Nonostante la differenza di prospettive, emerge tuttavia per entrambi la necessità che il discorso intorno alla scienza sia affrontato mediante il paradigma dell’etica.
Educare la libertà e il discernimento
2015
L'articolo parte dal dato evidente che si danno gesti di libertà autentica; analizza tre interpretazioni della libertà, quella liberista quella liberale e quella liberante. Quest'ultima è quella conveniente all'educazione di una persona; nel saggio se ne parla come educazione della virtù del discernimento e come "apprendere ad ascoltare la voce della coscienza".
