Whole genome sequencing of the black grouse (Tetrao tetrix): reference guided assembly suggests faster-Z and MHC evolution

2014

Background The different regions of a genome do not evolve at the same rate. For example, comparative genomic studies have suggested that the sex chromosomes and the regions harbouring the immune defence genes in the Major Histocompatability Complex (MHC) may evolve faster than other genomic regions. The advent of the next generation sequencing technologies has made it possible to study which genomic regions are evolutionary liable to change and which are static, as well as enabling an increasing number of genome studies of non-model species. However, de novo sequencing of the whole genome of an organism remains non-trivial. In this study, we present the draft genome of the black grouse, wh…

A Controllable Text Simplification System for the Italian Language

2021

Text simplification is a non-trivial task that aims at reducing the linguistic complexity of written texts. Researchers have studied the problem by proposing new methodologies for addressing the English language, but other languages, like the Italian one, are almost unexplored. In this paper, we give a contribution to the enhancement of the Automated Text Simplification research by presenting a deep learning-based system, inspired by a state of the art system for the English language, capable of simplifying Italian texts. The system has been trained and tested by leveraging the Italian version of Newsela; it has shown promising results by achieving a SARI value of 30.17.

Abuso del diritto e diritto penale: un pericoloso ossimoro.

2020

L’articolo tratta del delicato e complesso concetto di abuso del diritto, nato nel campo del diritto civile e poi approdato in sede penale nel settore del diritto penale tributario. Nell’articolo si ritiene che tale nozione non è compatibile con i princìpi fondamentali del diritto penale italiano e che, pertanto, non vi dovrebbe avere ingresso.

The article deals with the delicate and complex concept of abuse of law born in the field of civil law and then landed in criminal law in the field of criminal tax law. In the article it is believed that this notion is not compatible with the fundamental principles of Italian criminal law and that therefore it should not have access to it.Settore IUS/17 - Diritto Penale

SULLA FIABA E SULLA LETTERATURA PER L'INFANZIA A PROPOSITO DI ALCUNI LIBRI

2023

L’articolo riflette su alcune proposte critiche contenute nel recente volume Di cosa parlano i libri per bambini. La letteratura per l’infanzia come critica radicale di Giorgia Grilli, studiosa di letteratura per l’infanzia da molti anni e traduttrice di classici della critica e della narrativa per ragazzi. Attingendo alle scienze cognitive, agli studi di antropologia, di psicologia degli archetipi, di filosofia e alla tradizione critica di settore, Grilli si interroga sul vero significato delle storie per bambini, sulla dimensione profondamente filosofica che alcuni classici per l’infanzia possiedono per dimostrare la complessità letteraria e antropologica di un ambito letterario ingiustam…

The article reflects on some critical proposals contained in the last essay What children's books are about. Children's literature as a radical critique by Giorgia Grilli a scholar of children's literature for many years and translator of critical classics and children's fiction. Drawing from the cognitive sciences the studies of anthropology the psychology of archetypes philosophy and the critical tradition Grilli questions the true meaning of children's stories the profoundly philosophical dimension that some classics for children possess to demonstrate their literary and anthropological complexitySettore L-FIL-LET/10 - Letteratura Italiana

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.

Tutela e sicurezza del lavoro tra centro e periferia: la sicurezza sui luoghi di lavoro

2013

Il saggio prende in esame la complessa questione del riparto di competenze tra Stato e Regioni alla luce del Titolo V della Costituzione in materia di salute e sicurezza sui luoghi di lavoro. Il riparto di competenze tra centro e periferia è stato oggetto di una limitata analisi da parte della dottrina e della giurisprudenza, che si sono concentrate in particolare sulla disciplina del mercato del lavoro. L’Autore descrive un sistema multilivello, caratterizzato dalla compresenza di fonti nazionali e regionali, della contrattazione collettiva, nonché di codici di condotta. Sulla scorta di una ricostruzione del quadro normativo e dei percorsi della giurisprudenza, il saggio propone una lettur…

The essay examines the complex issue of the division of powers between the State and the Regions according to Title V of the Constitution concerning health and safety at workplace. This division between the center and the periphery has been subject to a limited review by doctrine and jurisprudence expecially focusing on the regulation of labour market. The Author describes a multilevel system characterized by the presence of national and regional sources collective bargaining and codes of conduct. On the basis of a reconstruction of the regulatory framework and the judicial statements the paper proposes a dynamic reading of the relationship between center and periphery in which the axis of the system remains however anchored to the national jurisdiction along with important regulatory issues left to the regional legislation.Settore IUS/07 - Diritto Del Lavoro

Canopy Architecture Appraisal by Fractal Dimension of 'Flordastar' Peach Trees Grafted onto Different Rootstocks

2007

The objective of this research was to evaluate the modification of canopy architecture of ''Flordastar'' peach (Prunus persica L. Batsch) grafted onto rootstocks with different vigour by the use of fractal dimension (D). The hypothesis was that different vigour rootstocks are able to modify the complexity of the branching pattern and that this effect can be assessed by a geometric parameter such as the fractal dimension (D) of the 2D projection of tree branching structure. The observations were carried out in a four-year-old experimental orchard of cv. ''Flordastar'' peach trees grafted onto Ishtara Barrier GF677 and MrS 2/5 rootstocks. On digital pictures of leafless dormant peach trees the tree skeleton was manually depicted by an image analysis software to measure total length and angles of insertion of branches. Bitmaps of the skeleton were then subjected to a specific software (FDCALC) able to calculate D by the "box counting" method. To account for the error introduced by analyzing a three dimensional structure with its 2D projection measurements were done on two images per tree taken from two different viewing angles. Results are shown in relation to tree vigour of the scion/stock combination. Fractal dimension was related to the vigour ranking of the graft combinations tested. In particular vigorous scion/stock combinations showed the highest D.HorticultureCanopy architectureHorticultureRootstockFractal dimensionMathematics

The Italian Method of la drammatica: its Legacy and Reception

2014

The volume The Italian Method of la drammatica: its Legacy and Reception includes the long and complex investigation to identify the Italian acting-code system of the drammatica used by nineteenth-century Italian actors such as Adelaide Ristori Giovanni Grasso Tommaso Salvini Eleonora Duse. In particular their acting inspired Stanislavky who reformed twentieth-century stage. The declamatory code of the drammatica was composed by symbols for notation of voice and gesture which Italian actors marked in their prompt-books. The discovery of the drammatica’s code sheds new light on nineteenth-century acting. Having deciphered the phonetic symbols of the code Anna Sica has given birth an investigation with a group of outstanding scholars in an attempt to explore the drammatica’s legacy and its reception in Europe as well as in Asia. At this stage new evidence has emerged proving that for instance the symbol used by the drammatica actors to sign the colorito vocale was known to English actors in the second half of the nineteenth century. By noting how Adelaide Ristori passed on her art to Irving’s actress Genevieve Ward and how Stanislavsky almost aflame moulded his system from Duse’s acting an unexplored variety in the reception of the drammatica’s legacy is revealed.Settore L-ART/05 - Discipline Dello Spettacolo

On the impact of forgetting on learning machines

1995

People tend not to have perfect memories when it comes to learning, or to anything else for that matter. Most formal studies of learning, however, assume a perfect memory. Some approaches have restricted the number of items that could be retained. We introduce a complexity theoretic accounting of memory utilization by learning machines. In our new model, memory is measured in bits as a function of the size of the input. There is a hierarchy of learnability based on increasing memory allotment. The lower bound results are proved using an unusual combination of pumping and mutual recursion theorem arguments. For technical reasons, it was necessary to consider two types of memory : long and sh…
