Jerre Mangione, 4th Annual ODU Literary Festival
No full textLike everyone else, writers needed to eat during the Depression, and the federal government put more than six thousand of them to work in what W.H. Auden called one of the noblest and most absurd undertakings ever attempted by any state. Jerre Mangione, former national coordinating editor of the Federal Writers\u27 Project (1935- 1943), will tell the story of this exciting and controversial branch of the WPA and relate it to the current economic conditions facing today\u27s creative writers.
Mangione is the author of ten books of fiction and non-fiction, including the best-selling memoirs Mount Allegro and An Ethnic at Large. His Wednesday afternoon talk comes from his book The Dream and the Deal, hailed by Alfred Kazin as one of the best social histories of American writers in our time
Progetto di Riqualificazione della Piazza del popolo a Latina - "Fundus"
No full textIl progetto esalta la peculiarità dell'architettura e del paesaggio della città di fondazione, rinviando alla tradizione artistica locale, in particolare all'opera di Duilio Cambellotti. Ad essa vengono combinate la cultura agricola romana, l'agrimensura e le tecniche di irrigazione tradizionali, trasfigurando nel disegno della piazza l'antica tecnica irrigua della marcita. Il risultato è un progetto di grande impatto pittorico che recupera il valore figurativo ed identitario di un territorio contrassegnato dalla bonifica, senza rinunciare alla funzionalità ed alle richieste di uno spazio urbano contemporaneo
Il "nuovo" ruolo dell'assemblea nelle società quotate
No full textThe evolution of the international scene demonstrates the relevance of the debate regarding
the role of shareholders in listed companies. For a long time, all attempts to encourage shareholder
activism had been branded as an anachronistic return to the so-called “shareholder democracy”. In
recent years, however, the assumption of equivalence between the increase of shareholders’ rights
and the reduction of efficiency in the management of a company has been disproven, at least at the
legislative level.
The development of the Italian legislative framework in the last ten years has actively
contributed to the strengthening of the role of shareholders in listed companies. In fact, the Italian
legislator has not only transposed the European provisions (Directive 2007/36/EC), which have
facilitated the participation of shareholders in general meetings but, in addition, he has prepared a
package of substantial competences that provide shareholders with the capability to influence
corporate governance of the company and to express “publicly” their dissent against the activity of
management, with possible impact on the market value of securities.
In the light of the above, it is important to investigate the reasons and contents of the choices
of European and national legislators, which (in line with the present trend in the world) have been
made to encourage shareholder engagement in order to improve corporate governance of listed
companies.
Along this line of inquiry, the research project aims to examine the role that shareholders in
listed companies have currently taken in Italy, first of all on the basis of the analysis of the positive
framework and data available from recent general meetings.The evolution of the international scene demonstrates the relevance of the debate regarding

Impact of Spreading Factor Imperfect Orthogonality in LoRa Communications
No full textIn this paper we study the impact of imperfect-orthogonality in LoRa spreading factors (SFs) in simulation and real-world experiments. First, we analyze LoRa modulation numerically and show that collisions between packets of different SFs can indeed cause packet loss if the interference power received is strong enough. Second, we validate such findings using commercial devices, confirming our numerical results. Third, we modified and extended LoRaSim, an open-source LoRa simulator, to measure the impact of inter-SF collisions and fading (which was not taken into account previously in the simulator). Our results show that non-orthogonality of the SFs can deteriorate significantly the performance especially of higher SFs (10 to 12) and that fading has virtually no impact when multiple gateways are available in space diversity
No Black Box: Promoting Inclusion and Democracy in The Age of Artificial Intelligence
No full textThis work dissects how the ascendant role of AI in adjudicating citizenship status is leading a new kind of citizenship shaped by digital interactions: the "Algorithmic Citizenship". The analysis delves into the threat of algorithmic discrimination and of algorithmic historical revisionism. The work emphasizes the importance of explainability and transparency in algorithms and it examines the challenges posed by their “black box” nature
ABCs of hemodiafiltration prescription: The Pisa style
No full textIn end-stage kidney disease patients, hemodiafiltration, a mixed diffusive-convective technique, has shown beneficial effects in terms of improvement of anemia, inflammation, mineral bone disorders, malnutrition and cardiovascular stability. Greater convective volume exchange was also associated with improved overall and cardiovascular survival. However, absolute target threshold volume would be difficult to define and achieve in daily clinical practice, mainly because of differences in patient size. Convective volumes standardized for body surface area would appear to be the simplest approach in clinical practice. Several factors can affect achievement of optimal convective volume, with vascular access being the main limiting factor. Based on our own clinical experience, hemodiafiltration is a more effective and preferable dialysis technique but only when a target convective volume greater than 20 L can be achieved. Conversely, standard high flux hemodialysis or expanded hemodialysis may be helpful and valuable alternative dialysis techniques

No full textIn this demo, we prove that the flexibility supported by off–the–shelf IEEE 802.11 hardware can be significantly ex- tended if we move the control of the MAC programming interface from the driver to the firmware, i.e. from the host CPU to the card CPU. To this purpose, we introduce the concept of MAC–Engine, that is an executor of Pro- grammable Finite State Machines (PFSM) implemented at the firmware level: we show how the card itself can support different protocol logics thanks to PFSM bytecode repre- sentations that can be dynamically injected inside the card memory at run-time without incurring in down time issues or network disconnect events. We provide different PFSM examples in order to test the functional thoroughness of the programming interface provided by the MAC–Engine archi- tecture. Finally, we introduce an experimental PFSM de- velopment framework, that can translate a graphical PFSM representation into an optimized bytecode
Costruire un arco irrealizzabile
No full textL'articolo ricostruisce le vicende legate al progetto per la costruzione dell'Arco monumentale per l'E42 a Roma. In particolare, esso mette a fuoco lo sforzo colossale compiuto per realizzare un'opera considerata, a buon diritto, pionieristica, ma di cui fin dall'inizio emergeva la complessità insormontabile. Alla descrizione delle numerose modifiche apportate, nella forma e nei materiali, all'idea originale, si affianca il doppio filo con il contesto politico, collegato in maniera inappellabile all'avvento della guerra: lo slancio iniziale legato all'impresa, testimoniato dal dibattito coevo, cede al progressivo disincanto fino all'inevitabile abbandono dell'opera. Si delineano, così, i contorni di una sfida impossibile destinata al fallimento.The article describes the story of the Monumental Arch of the E42. Leading through the evolution of the project in its different versions, it follows the trajectory of this challenge from the initial enthusiasm to the disillusion due to the technical complexity, but also to the political context and the beginning of the II World War. Therefore, despite the colossal effort and the fact that some design proposals were virtually plausible, the result is the failure of the project
