Can you feel it will you tell me. Encouraging sentiment expression on the web
2015
In a recent trend in web communication, news outlets and blog platforms allow readers to express opinions about what they have read by choosing an associated feeling, or sentiment ex- pression. This emerging trend, fitting between liking and full text comments, has not still found the popularity it should. The thesis of this paper is that this is also due to the way the sen- timent choice is presented to the user. In order to test this hy- pothesis we have devised a pilot experiment; results confirm that a simpler way of choice increases sentiment expression and yields result that are more aligned with ground truth.
Optimization of a thermomagnetic motor
2015
In this paper, an approach towards the optimization of the Curie motor is presented. The approach is based on a thermal-magnetic coupled dynamic model of the motor, which is obtained by assuming the use of a ferromagnetic material working at temperatures near the Curie point. An analytical expression of the generated torque, which links this quantity to the magnetic, thermal, and geometrical parameters of the generated torque, is given. The expressions of speed and torque are derived and related to the thermal properties of the machine and are used as optimization indexes in an optimization procedure. The aim of the optimization process is to obtain a machine able to rotate constantly at th…
Identification of Key miRNAs in Regulation of PPI Networks
2020
In this paper, we explore the interaction between miRNA and deregulated proteins in some pathologies. Assuming that miRNA can influence mRNA and consequently the proteins regulation, we explore this connection by using an interaction matrix derived from miRNA-target data and PPI network interactions. From this interaction matrix and the set of deregulated proteins, we search for the miRNA subset that influences the deregulated proteins with a minimum impact on the not deregulated ones. This regulation problem can be formulated as a complex optimization problem. In this paper, we have tried to solve it by using the Genetic Algorithm Heuristic. As the main result, we have found a set of miRNA…
Il coordinamento tra gli articoli 8 e 10 CEDU in una recente pronuncia della Supreme Court inglese
2022
Lo scritto prende in considerazione il tema del possibile conflitto tra il dirit- to al rispetto della vita privata sancito dall’art. 8 CEDU e la libertà di espressio- ne riconosciuta dall’art. 10 della stessa Convenzione. L’indagine viene condotta traendo spunto da una recente sentenza della Supreme Court inglese nel caso Bloomberg in cui si dibatteva circa la liceità della pubblicazione della notizia dell’esistenza di indagini riguardanti il dirigente di una società, prima ancora e senza che nei suoi confronti fosse stata ufficialmente formulata alcuna ac- cusa penalmente rilevante. La risposta negativa in tutti e tre i gradi del giu- dizio, in cui fu accertata l’esistenza del diritto del…
Disinformation and Hate Speech: A European Constitutional Perspective
2020
What balance should be struck between freedom of expression, as an essential right and value of any democratic society, and other constitutional rights when facing falsehood and extreme speech? How are Europe and legislators around the world reacting to the rise of online disinformation and hate speech, in the wake of mounting evidence of adverse effects on democratic processes? What is the most effective approach to address and tackle harmful practices over the Internet, if any? These are some of the pivotal questions that this book seeks to explore.
Parole e potere. Libertà d'espressione, hate speech e fake news
2017
indagine in tema di libertà di espressone che parte dalle origini del costituzionalismo contemporaneo e si muove poi lungo le coordinate relative alla giurisprudenza della Corte suprema statunitense e delle Corti europee, nel processo di transizione dell’esercizio di diritti e libertà fondamentali dal mondo degli atomi a quello dei bit. investigation on the subject of freedom of expression that starts from the origins of contemporary constitutionalism and then moves along the coordinates relating to the jurisprudence of the US Supreme Court and the European Courts, in the transition process of the exercise of fundamental rights and freedoms from the world of atoms to that of bits.
Mercato delle idee e fake news. Note su un problema di esternalità negative nell’ambiente digitale
2023
The spread of fake news in the digital arena has put into question the traditional idea of the self-regulation of public debate: the well-known metaphor of “free market of ideas”. Because of the availability of digital media, the reduction of the overall cost in producing and disseminating false news has dramatically fallen. Everybody at any time can enter the public debate, even though with bad arguments. At the same time, the competition between traditional and digital media has produced an astonishing reduction of the average incomes of the professional journalists. This paper aims to bring to the fore the metaphor of the market of ideas, metaphor that has been used in the US for reducin…
The marketplace of ideas and its externalities: Who pays the cost of online fake news?
2023
Since the nineteenth century, thanks to J.S. Mill, an argument against limiting the freedom of expression has been gaining ground, namely that the truth of an argument is the result of free competition between different ideas in a “marketplace of ideas” and that this competition can yield an approximate form of the truth or a robust argument. In this paper I will argue that Mill’s model of the marketplace of ideas is an “idealised” model because it assumes that there is a subject who seeks to know in a detached manner, without being influenced by his or her expectations, needs, ideologies, or biases. However, the metaphor of the marketplace of ideas is still relevant because it also harbour…

Parole cattive: la libertà di espressione tra linguaggio, diritto e filosofia
2022
Questo libro parla del lato oscuro – offensivo, violento, ingannevole – delle parole. Lo fa mettendo in dialogo studiosi di competenza diversa, tutti mossi dalla profonda consapevolezza dei dirompenti effetti delle parole sulla vita delle persone. Si tratta, dunque, di un dialogo sul potere delle parole; o meglio, di un insieme di quattro dialoghi tematici su differenti questioni che sorgono quando si ragioni su quel potere. Il paradosso del cospirazionista come parresiasta, che afferma cose contrarie all’evidenza, pretendendo di svelare così verità nascoste. Il rapporto fra verità e libertà di parola: qual è il modo più ragionevole di tenere insieme libertà di parola, verità scientifica e …
