Tre leve strategiche per il benessere organizzativo: welfare aziendale, lavoro agile e partecipazione
No full textThe article draws attention to the ways in which, within the current processes of transformation, remote work and corporate welfare programs can act positively on the personal and professional needs of workers. It also broadens its gaze to that fuller manifestation of subjectivity that technologically advanced work, at every level, increasingly demands, questioning what the ways might be for its expression within processes of technological and organizational innovation. Such processes, in order not to be anti-human, require an integral recognition of the person at (and in) work so that the latter can lead to the self-realization of each person
Pesenti–Szpiro inequality for optimal elliptic curves
No full textAbstractWe study Pesenti–Szpiro inequality in the case of elliptic curves over Fq(t) which occur as subvarieties of Jacobian varieties of Drinfeld modular curves. In general, we obtain an upper-bound on the degrees of minimal discriminants of such elliptic curves in terms of the degrees of their conductors and q. In the special case when the level is prime, we bound the degrees of discriminants only in terms of the degrees of conductors. As a preliminary step in the proof of this latter result we generalize a construction (due to Gekeler and Reversat) of 1-dimensional optimal quotients of Drinfeld Jacobians
An integer programming formulation to allocate series of slots on an airport network
No full textSeveral authors have introduced mathematical formulations for the airport slot allocation process, and the initial allocation in particular. They mostly replicate the current IATA process, performed on an airport-by- airport basis. However, airports are part of a network. The initial slot allocation should therefore be performed simultaneously at all airports, accounting for flight times to link departures and arrivals. [1] proposes an integer programming formulation to allocate a set of single-day slots on a network of airports. Extending that formulation, this paper additionally models the IATA rule stating that series rather than individual slots are to be allocated. A series of slots includes at least 5 slots at the same time and day-of-the-week, distributed regularly in a season. The objective of the allocation is to minimise airline costs due to the non-allocation of series of slots, their temporal displacement, and the deviation from the requested block or turnaround time for slots of coupled series. Preliminary experiments are based on a network of 152 European airports and consider about 300000 slot requests for seven Fridays of the 2017 summer season. Results quantify the increase of airline costs as a function of congestion.

Ut medicina poësis. Sulla ‘terapia’ del “Decameron”
No full textIl saggio indaga il rapporto fra il "Decameron" e la cultura medica del tempo, accertando lo stretto nesso che congiunge Boccaccio a quel versante della cultura medica che vedeva nella parola umana un metodo per curare, non solo per alleviare, i mali dell'uomo e le tragedie della storia
