    Description: The persistent open-vent degassing of Mt. Etna is often punctuated by monthslong paroxysmal sequences characterized by episodes of violent Strombolian to lava fountaining activity. Understanding these gas-fueled transitions from quiescence to eruption requires routine measurement of gas fluxes. Here, we report SO2 flux measurements, obtained from a permanent UV camera system, collected over a two-year-long period spanning two paroxysmal sequences of Etna’s New South East Crater (NSEC) in December 2020/April 2021 and May/ October 2021. In both cases, SO2 flux increased from ≤ 3250 Mg/day during “ordinary” activity to ≥ 4200 Mg/day. We interpret these distinct SO2 degassing regimes in light of seismic and thermal observations and drawing on numerical simulations of sulfur degassing constrained by parental melt sulfur contents in Etna’s hawaiites. We find that initiation of a paroxysmal sequence results from an approximate doubling of the time-averaged rate of magma supply (and degassing) above the sulfur exsolution level (~150 MPa pressure), to 〉4m3/s. This corroborates recent models that argue for the triggering of paroxysmal sequences by escalating supply of volatile-rich magma to a reservoir ~3–4 km below the summit region. The non-stationary nature of magma flow and volcanic degassing we identify highlights the need for sustained surveillance to characterize long-term atmospheric budgets of volcanic volatiles

    Description: This book is a collection of contributions by the Italian scholarship fellows at the Deutsches Historisches Institut of Rome over the last decade. It is intended as a tribute to one of the leading mediaevalists at international level, a scrupulous and sensitive scholar of Italian history. Over and above all this, it is a sign of gratitude from the young academics who have been able to consolidate their research thanks to such scholarships. Consequently the 14 contributions that make up the book do not share the academic orientation of any particular school, but range over various research sectors and different chronological periods.
    Description: Il volume, che raccoglie i contributi di ex borsisti italiani dell'ultimo decennio del Deutsches Historisches Institut di Roma, vuole essere un omaggio a uno dei medievisti più noti a livello internazionale e all'attento e sensibile studioso della storia italiana, ma soprattutto un segno di gratitudine di giovani studiosi che con tale borsa hanno potuto consolidare i loro percorsi di ricerca. I 14 contributi che lo compongono non sono quindi accomunati da un comune orientamento formativo di scuola, ma spaziano fra diversi settori di ricerca e differenti ambiti cronologici.

    Description: The book focuses on the particular historical-political context of the Kingdom of Naples in the Aragonese period (1442-1503), and explores the variety of languages related to political practice: juridical, literary, artistic, political languages are analyzed in their specificities, but also in their reciprocal osmotic relations. This volume offers a conclusive reflection after a conference organized in Naples, and integrates interdisciplinary perspectives. It tests and refines the hypothesis concerning the gradual development of a complex organism that – through literature, oratory, political treatises, artistic representations and administrative practices – goes in the direction of a “state system”, which still operates under the guidance of sovereignty.
