Sistemi di comunicazione e dispositivi di interfaccia per l'integrazione della generazione distribuita nelle smart grids
2014
L'integrazione della generazione distribuita (GD) nelle reti elettriche di distribuzione a media e bassa tensione uno degli elementi chiave per il pieno sfruttamento delle fonti energetiche rinnovabili (FER). Ci implica un ripensamento della gestione e del controllo delle reti elettriche , che devono passare da sistemi " passivi ", con flussi di potenza unidirezionali e un numero limitato di funzioni di monitoraggio e automazione, a reti attive e intelligenti (Òsmart gridsÒ). In tali sistemi, i flussi di potenza possono essere bi-direzionali e, se non correttamente gestiti, possono causare situazioni critiche, quali ad es. problemi di stabilit e di controllo della rete o funzionamento i…
Aristóteles entre doxografía y biografía: sobre Diógenes Laercio V 31
2019
Se pretende llamar la atención sobre un par de frases que aparecen justo hacia la mitad de la controvertida doxografía de Aristóteles que se puede leer en las Vidas y doctrinas de los filósofos más ilustres de Diógenes Laercio V 31, y que desde luego no corresponden a ningún sistema doxográfico conocido. Como sucede no pocas veces en la obra laerciana, la misma apreciación sobre si el filósofo debe o no enamorarse y contraer matrimonio se repite idéntica en otras doxografías completamente distintas: la cirenaica (DL II 91), la estoica (DL VII 129) y la epicúrea (DL X 118). Cabe plantearse, pues, el origen de este interés, en varias doxografías, por la vida sentimental, podríamos decir, de l…
TEACHER AUTHORITY IN SCHOOL
2019
The purpose of education is to initiate the young into the different ways in which, over the centuries, men have organized their experience and understanding of the world. This initiation depends upon the ability of teacher to explain and inspire, and on the willingness of the young to engage in this enterprise with a proper humility. The discussion on the role of authority in knowledge development and the subject of lack of teacher's authority is in great tension. The role of the teacher has changed, authority, a fundamental part of the teaching–learning process, is a problematic and questioned by society, the media, parents and students. Due to the fact that the teacher is in the role of …
Reflexions on the introduction of the vocabulary of regulation in the field of law during the XVIIIth century and on its contemporary use
2017
According to a recurring lesson, the vocabulary of regulation would be of late introduction in the law language. Indeed, law professors substantiate this theory, conveyed by the sociologists : this word family would have first been introduced by the social sciences at the end of the XIXth century, before any use by the world of law. The present study tends, on the contrary, to demonstrate the existence and the continuity of the idea of regulation in law since the introduction, in the XVIIIth century, of the polysemous figure of the regulator ; a two-headed figure, applied as well to a power as to a judicial institution and to law, which separates and sometimes involves the regulation of a m…

Social media and consumer power : Opportunities and challenges for digital marketing activities
2021
Social Media (SM) have not only become an important part of daily life for individuals, governments and organisations but have also transformed the way people work, learn, consume and socially interact. There are many SM uses, posting frequencies and content preferences. User participation also varies from passive to more active behaviours, depending on the motivation for engagement in online conversations. From a marketing perspective, SM have redefined the traditional company - consumer relationship by progressively shifting power from marketing managers to consumers. Organisations are increasingly interested in understanding how SM can benefit (or harm) consumer-brand relationships, incr…
Social network site communities as agents and spaces of pursuing influence in society : forms, stages and attributes of building communicative power
2018
Before the emergence and high popularity of social media, individuals or even collectives of individual citizens rarely had strong voice in public discourse. Social media, and its social network sites (SNS), have allowed individual people to form communities to create discourse around issues they find meaningful, and even unite their power to fight for a common cause and potentially influence changes in society. The objectives of the thesis were to investigate what types of ‘societal influence (SI) oriented SNS communities’ the Internet and social media arena consists of and how their potential communicative power is formed, even to the extent that they can challenge news media and business…
