INTERPRETARE IL CAMBIAMENTO DEI SISTEMI ECONOMICI TERRITORIALI: PROCESSI, FRATTURE, RICOMPOSIZIONI
No full textThe goal of this work is to present most appropriate interpretations to understand the evolution of territorial
economic systems, in the current economic scenario, characterized by remarkable changes both in time and in space. To
meet this objective, we suggest some analysis perspectives and we introduce the concept of fracture, which indicates the
interruption in the evolution of a phenomenon and the emergence of a crisis situation, but also discontinuities and
orientation towards new development trajectories and new system structures. More precisely, we propose a territorial
analysis which integrates: the diachronic analysis, oriented to reconstruct the economic trajectories and to identify the
interruptions (temporal fractures) and the steps towards other development dynamics; the synchronic analysis, which aims
to capture the traces of the processes on regional economic forms and to identify the development differences (territorial
fractures); the relational analysis, aimed at describing the internal and external relationships and the fragmentation of the
phenomena that occur at different spatial scales (transcalar fractures). Using these perspectives of analysis, we examined
the economic system of Pisa, trying to understand its development trajectories, the transformations left in the territorial
structures, the emergent fractures, the dynamics of reconstruction and change
Piattaforme digitali e distribuzione ineguale dell’accesso al cibo: leggere i divari dei servizi di food delivery durante la pandemia
No full textDigital platforms and unequal food accessibility: reading the gaps in food delivery services during the
pandemic. Digital on-demand food delivery platforms (known in the literature as OFD, Online Food Delivery) have
helped to ensure access to food during the Covid19 pandemic, while catering establishments underwent closures or
scheduling and some commercial food complexes became difficult to reach and usable due to the limitations imposed
273
on movements and accesses. This work is part of the geographical debate on OFD platforms and intends to focus on
how they represent opportunities, but also factors that create margins, as well as other tools made possible by the fourth
revolution (Lazzeroni and Morazzoni, 2020). More precisely, the goal is to observe the situations of inequality that seem
to have emerged in this area during the pandemic (Bissell, 2020) due to two types of barriers to access to services: the
presence/absence of the service in the different areas and the lack of digital infrastructure in some areas of the country.
The context of the Italian OFD will be studied through a micro-biopolitical lens that connects the power relations, the
market relations (capitalist and techno-capitalist), and the governance/smart-mentality processes through which the OFD
is disciplined and managed in the cities

Abstract
Urinary sodium excretion, central hemodynamics, and mean arterial pressure (MAP) were studied in 7 normal subjects and 19 hypertensive patients during both central hypervolemia by water immersion to the neck (NI) and extracellular volume expansion by i.v. saline infusion. During 2-hour NI, 12 out of the 19 hypertensives exhibited a significant fall in MAP (p less than 0.001). Exaggerated natriuresis did not occur in these patients (ns). In the remaining 7 hypertensive patients in whom, during NI, MAP was unchanged, exaggerated natriuresis was found (p less than 0.001). During saline infusion, MAP was either unchanged or increased and exaggerated natriuresis was found in all hypertensive patients (p less than 0.001) previously submitted to NI. Our findings suggest that a high MAP is a major determinant of exaggerated natriuresis in arterial hypertension

Il parossistico “mercato” dei contratti collettivi
No full textDopo un’indagine dei mutamenti dell’attuale quadro regolativo, onde cogliere le dinamiche messe in atto, in particolare sul fronte sindacale, ispettivo e giurisprudenziale, per sopperire alla fuga dal sindacato e dal contratto collettivo maggioritario, ingenerata dall’incontrollato proliferare di accordi sindacali minori, l’A. riflette su paradossi, dinamismi e immobilismi del nostro sistema di contrattazione collettiva.After an investigation of the changes in the current regulatory framework, in order to grasp the dynamics implemented, in particular by trade unions, labour inspectors and the jurisprudence, to make up for the escape from the unions and majority collective agreements generated by the uncontrolled proliferation of “minor” union agreements, the Author reflects on paradoxes, dynamism and immobilism of our system of collective bargaining
