Quote rosa e parità tra i sessi: la storia di un lungo cammino

2019

Article 3.1 of the Italian Constitution enshrines the principle of equality and the prohibition of discrimination, based on “gender, race, language, religion, political opinion, personal and social conditions”. Additionally, Article 48 grants an equal right to men and women to vote, and Articles 56.3 and Article 58.1 establish the right to be elected to the Camera dei Deputati and the Senato della Repubblica without any reference to the gender of the candidates. Men and women voted in Italy the first time in an institutional referendum on 2 June 1946 to choose between a Republic and a Monarchy. However , the right for women to be elected came many years later, after a long and hard-fought s…

Il delitto di "caporalato" tra diritti minimi della persona e tutela del mercato del lavoro

2020

Il contributo analizza il reato di intermediazione illecita e sfruttamento lavorativo, offrendo un’analisi comparata con il sistema repressivo tedesco. Lo studio si sofferma, in particolare, sui limiti di legittimazione del diritto penale nella punizione dei fatti di “caporalato”, nel tentativo di scongiurare che l’intervento repressivo nelle dinamiche economiche e contrattuali, di natura sinallagmatica, possa assumere una portata tale da porsi in contrasto con il canone della sussidiarietà. A tal fine, si suggerisce una prospettiva ermeneutica che incentri il disvalore penale del reato di cui all’art. 603-bis c.p. sulla lesione dei diritti fondamentali del lavoratore – riconducibili agli a…

Settore IUS/17 - Diritto PenaleThe paper analyses the offence of unlawful work intermediation and exploitation offering a comparative analysis with the German punitive system. The study focuses in particular on the limits of legitimacy of criminal law in the punishment of gangmaster acts in the attempt to avoid that the punitive intervention in economic and contractual dynamics of a mutual nature could be so intrusive to be in contrast with the principle of subsidiarity. To this end the author suggests an interpretative perspective that centres the penal disvalue of the offence under article 603-bis of the criminal code on the harm to fundamental workers’ rights – as linked to articles 4 35 and 36 of the Italian Constitutions – which work as a limit to entrepreneurial freedom. To be sure the indexes of exploitation listed by the criminalising norm seem to echo those fundamental human rights attributed to a person as a worker: those very same rights that – when harmed in their minimal and therefore intangible dimension – legitimise the intervention of the ius terribile. The article also stresses the protection of the job market: in this sense the offence – even if situated within the Kernstrafrecht – represents a new paradigm of the institutional response within the framework of the contemporary relationships between law and economics.

L’exemplum del Dinomenide Gelone tra memoria civica e storiografica

2015

La storia della Sicilia greca è scandita, nei suoi momenti chiave, dalla persistente presenza dell’immagine del Dinomenide Gelone. Questo lavoro analizza le valenze paradigmatiche assunte dalla sua figura nella memoria civica siracusana e nella produzione storiografica; inoltre ricostruisce le dinamiche politiche che hanno spinto i principali tiranni siracusani (da Dionisio I a Ierone II) a stabilire un confronto con Gelone. Il suo exemplum è utilizzato per legittimare azioni politiche e impegno antipunico; particolare attenzione è posta alla Biblioteca storica di Diodoro Siculo e al ruolo che in essa assume la figura del Dinomenide; in relazione a questi aspetti l’opera dell’Agirinense sem…

Settore L-ANT/02 - Storia GrecaThe history of Greek Sicily is marked at its key moments by the persistent image of Dinomenid Gelon. This work analyses the paradigmatic value taken on by his figure in the civic memory of the people of Syracuse and in historiographic production. It also reconstructs the political dynamics which pushed the principal tyrants of Syracuse (from Dionysius I to Hiero II) to establish comparisons with Gelon. His exemplum was used to legitimate political actions and commitment against the Carthaginianparticular attention was also given to the Library of History of Diodorus Siculus and the role that the figure of Dinomenid assumes in itregarding these aspects the work of this author seems to have sometimes the signs of a personal interpretation of history: one that cannot always be explained in relation to the use of the two principal sources for Western history Timaeus and Philistos.

I marginalia di Dino Buzzati: schemi, illustrazioni e disegni

2022

Secondo questa proposta di lettura dell'opera grafica di Dino Buzzati, che può essere estesa anche ad altri autori dal doppio talento, i disegni ai margini della scrittura possono essere interpretati allora nella loro funzione di relazione tra le arti che si risolve in una interazione, una negoziazione, uno slittamento oppure un conflitto, una cancellatura. Inoltre le annotazioni ai margini della scrittura, soprattutto nelle loro versioni grafiche, costituiscono una forma di introspezione autobiografica assai preziosa per ricostruire il profilo del loro autore, se scrittore e disegnatore al contempo.

Settore L-FIL-LET/14 - Critica Letteraria E Letterature ComparateAccording to this proposed analysis of Dino Buzzati's graphic work which can also be extended to other doubly talented authors the drawings at the margins of writing can be interpreted then in their function as a relationship between the arts that results in an interaction a negotiation a slippage or a conflict an erasure. Moreover annotations in the margins of writing especially in their graphic versions constitute a form of autobiographical introspection that is very valuable for reconstructing the profile of their author if writer and artist at the same time.

Note di Abū Naṣr al-Fārābī sulla verità e falsità dell’astrologia

2020

Il presente contributo propone l’introduzione, la traduzione italiana e il commento delle Note sulla verità e falsità dell’astrologia (Nukat fī mā yaṣiḥḥu wa-mā lā yaṣiḥḥu min aḥkām al-nuǧūm) di Abū Naṣr al-Fārābī (m. 950). Tale scritto non è stato trasmesso direttamente dal suo autore né ci è giunto nella sua redazione definitiva, bensì in forma di appunti ricopiati da un grammatico di nome Abū Isḥāq al-Baġdādī. In trenta brevi capitoli al-Fārābī spiega ciò che è accessibile e ciò che è inaccessibile alle predizioni astrologiche e quali aspetti di tale scienza sia opportuno accogliere o respingere.

Design and analysis of discrete choice experiments for models with response time

2013

Settore SECS-S/02 - Statistica Per La Ricerca Sperimentale E TecnologicaA sector of conjoint analysis (experimental design in marketing research) is made of the so called choice experiments. In choice experiments respondents undergo a questionnaire which is nowadays mostly submitted through the internet. The questionnaire proposes to the respondent a sequence of choice sets each one including two or more profiles being a profile a specific combination of attribute levels. The respondent selects the preferred profile for each choice set. Responses given by a sample of respondents are analysed through suitable methods aimed to eventually find the best combination of attribute levels. One method of analysis adopts the Multinomial Logit (MLN) model. In this article the authors show the results of the MLN analysis compared with another model of analysis which uses an additional response which can be easily recorded by electronically submitted questionnaires. In practice modern survey platforms like “Qualtrics” (the one used for this work) can record the so called “response latency” i.e. the time taken by the respondent to make the choice and select the most preferred profile in the choice set. Thanks to a response latency model further refined in this work it is possible to deduce the relative weight of importance of the profiles for each choice set and respondent. This type of response can be used in place of the dichotomous choice variable in the MLN model. The two models and methods of analysis are deeply compared and it is critically discussed when it is better to use one or the other method. As a result a more reliable estimate of the optimal profile comes up implying lower risks for new investments and marketing decisions.

Appropriazione e (ri)semantizzazione dello spazio urbano: lo sport in una piazza palermitana

2019

Il contributo, attraverso uno studio di campo, con un approccio geografico culturale esplora le modalità attraverso cui uno spazio urbano, piazza Vittorio Emanuele Orlando a Palermo, può essere oggetto di complessi processi di (ri)semantizzazione. La piazza diviene infatti luogo per sport giovanili improvvisati, al centro di dialettiche opposte (ufficialità/improvisazione) e di forme multistratificate di socialità e aggregazione.

The chapter through a field study with a cultural geographical approach explores the ways in which urban space Piazza Vittorio Emanuele Orlando in Palermo can be the subject of complex processes of (re) semantization. In fact the square becomes a place for improvised youth sports at the center of opposing dialectics (official/improvisation) and multi-layered forms of socializing and aggregation.

Non-Linear Hysteretic Instability in Rotating Machinery

2013

The destabilizing influence of the shaft hysteresis on the supercritical whirl of rotating machines can be efficiently counterbalanced by proper external dissipative sources in the supports and/or anisotropic suspension systems. The hysteretic effect may be treated either by dry or viscous models obtaining different but somehow similar results in the hypothesis of small dissipation levels. Thus the linear viscous assumption is often accepted as a crude approximation for a straightforward analysis of the whirling instability. Nevertheless the internal friction should be regarded most likely as non-linear and could be approximated for example by Coulombian models taking thus into account also the releasing effect of some shrink-fit coupling present in the mechanical assembly.

Rapid and eco-friendly synthesis of graphene oxide-silica nanohybrids

2014

The increasing interest in Graphene oxide (GO) is due to many issues: the presence of both sp2-conjugated atoms and oxygen-containing functional groups provides a strong hydrophilicity and the possibility to further functionalize it with other molecules (i.e. π-π interactions covalent attachment etc.) [1]. Furthermore since the GO is biocompatible and noncytotoxic many studies have been recently focused on the development of GO-based nanodevices for bioimaging DNA detection drug delivery. Due to their low cytotoxicity and large internal surface area silica nanoparticles have been taken into account as promising material for biolabeling and drug loading/delivery. Particular consideration has recently been demonstrated for GO-silica composites because of the potentialities for electrical applications their chemical inertia and stability toward ions exposure. The possibility to combine the extraordinary properties of GO and silica offers several advantages for the realization of nanoprobes for biological applications and of biosensor [12]. The strategy for the fabrication of GO-nanosilica nanohybrids can be schematized as follows: (i) synthesis of GO by oxidizing graphite powder with the method described by Marcano et al. [3] (ii) Preparation of oxygen-loaded silica nanoparticles by thermal treatments in controlled atmosphere in order to induce high NIR emission at 1272 nm from high purity silica nanoparticles. (iii) preparation of GrO-silica nanohybrid films via rapid solvent casting in water. The nanohybrids were tested by XPS FTIR Raman analysis UV photoluminescence analysis TGA Zeta potential measurements electrical tests AFM and SEM. Several nanohybrids were prepared by combining two different typologies of GO and two different samples of silica.

Integrazione di celle fotovoltaiche ibride nel vetromattone

2012

L’invenzione riguarda l’integrazione del vetromattone con celle solari ibride (organiche/inorganiche), conosciute come Dye-sensitized Solar Cell (DSC). La combinazione del vetromattone con le DSC consente di migliorare le prestazioni del prodotto originario rendendolo in grado di produrre energia pulita. Le caratteristiche di trasparenza e isolamento termo-acustico del prodotto possono essere regolate agendo sulla configurazione delle DSC. Il prodotto può essere assemblato a formare pannelli fotovoltaici per la realizzazione di facciate traslucide energeticamente “attive” in varie condizioni luminose (condizioni di luce diffusa o artificiale) e indipendentemente dall’angolo di radiazione so…

The integration of Dye-sensitized Solar Cell (DSC) with the glassblock is disclosed. The combination of the two technological elements the glassblock and the DSC module enhance their own peculiarities. The final complete product is ready-made for installation owns the qualities of the glassblock and produces sustainable energy at the same time. The transparency and the thermo-acoustic insulation may be modulated according to the specific requirements of each case of installation. The product may be used for example to create PV panels for glazed and translucent façades that are able to perform efficiently in all light conditions (even in diffuse light also converting internal artificial light) that are not dependant on the angle of the solar radiation and do not suffer from the high operative temperatures of functioning due to the peculiarities of the DSCs. DSCs are made of economic and biocompatible materials and are produced with low-cost and highly productive printing methods on rigid or flexible substrates. With the integration of DSC modules with the glassblock PV panels coincide with the envelope itself so that they do not need any further structures to be installed on and allow the possibility of subtract from the price of the panel the price of the substituted building element allowing further economies. DSCs can be printed in different colours and with various patterns offering to designers and customers the possibility of intervening on the glassblock aesthetical aspect also taking advantage of the peculiar modularity of the glassblock for larger compositions of drawings on the building’s façade. Seven Hypotheses of integration are discussed in order to obtain DSC-integrated glassblock ready for the construction of a precast and dry-assembled PV panel which can use the horizontal and vertical cavities between the glassblocks to house plastic profiles where the electric interconnections and the steel bars -useful for improve the mechanical resistance of the panel- are integrated.Settore ICAR/10 - Architettura Tecnica
