Credit Risk and Simulated Spreads Risk Adjusted for Italian Regions.
2009
We analyse the idiosyncratic and systematic elements influencing Italian firms’ probability of default (PD) and examine the relationship between credit risk and borrowing conditions at a regional level. This paper, using regression analysis, examines the causal relationship between PD of a representative sample of Italian firms, together with accounting variables at firm level and macroeconomic data. The underlying hypothesis examines if the riskiness of Italian firms is influenced exclusively by their specific characteristics or, more generally, depends also on the spatial environment where they operate. According to the literature, the interregional differentials in the cost of money depe…
Background element content in the lichen Pseudevernia furfuracea: a comparative analysis of digestion methods
2019
In bioaccumulation studies, the interpretation of pollutant contents in the target biomonitor has to be performed by assessing a deviation from an unaltered reference condition. A common strategy consists in the comparison with background element content (BEC) values, often built up by uncritically merging methodologically heterogeneous data. In this respect, the acid digestion of samples was identified as a major step affecting BEC data. Here, the analytical outcomes of two acid mixtures were compared on a set of matched paired samples of the lichen Pseudevernia furfuracea, a widely used biomonitor for which BEC values based on partial digestion were previously provided. The standard refer…
Background element content of the lichen Pseudevernia furfuracea: A supra-national state of art implemented by novel field data from Italy
2018
Abstract In biomonitoring, the knowledge of background element content (BEC) values is an essential pre-requisite for the correct assessment of pollution levels. Here, we estimated the BEC values of a highly performing biomonitor, the epiphytic lichen Pseudevernia furfuracea, by means of a careful review of literature data, integrated by an extensive field survey. Methodologically homogeneous element content datasets, reflecting different exposure conditions across European and extra-European countries, were compiled and comparatively analysed. Element content in samples collected in remote areas was compared to that of potentially enriched samples, testing differences between medians for 2…

Cross-validation of δ15N and FishBase estimates of fish trophic position in a Mediterranean lagoon: The importance of the isotopic baseline
2013
Abstract FishBase, a relational database freely available on the Internet, is to date widely used as a source of quantitative information on the trophic position of marine fish species. Here, we compared FishBase estimates for an assemblage of 30 fish species sampled in a Mediterranean lagoon (Acquatina lagoon, SE Italy) with their trophic positions calculated using nitrogen stable isotopes. To assess the influence of the trophic level used to compute the baseline indicator on the robustness of isotopic estimations, we compared the trophic position of fish calculated using the average δ 15 N signature of either basal resource or primary consumer taxa measured at three stations located in th…
Banca e credito nel rapporto con le imprese: note finali.
2016
In questo capitolo vengono tracciate le conclusioni di questo percorso di ricerca. Il volume è rivolto ad un pubblico di studenti, imprenditori, manager, professionisti e personale bancario, e intende porsi come uno contributo conoscitivo utile alla comprensione delle linee evolutive dei rapporti creditizi banca-impresa, in un contesto istituzionale e competitivo caratterizzato da una crescente complessità tecnica ed operativa dell’attività creditizia, da un’incessante innovazione finanziaria, da una continua evoluzione della tecnologia informatica e telematica, e dalla complessa armonizzazione e unificazione della regolamentazione e vigilanza dell’industria bancaria europea.
Il rapporto banca-impresa: aspetti definitori e premesse teorico-metodologiche.
2016
Questo capitolo introduttivo, pur ponendosi l’obiettivo di analizzare i fondamenti teorici del rapporto banca-impresa, non vuole avere la pretesa di prendere in esame in modo esaustivo la copiosa letteratura teorica ed empirica sulle scelte di finanziamento delle imprese, struttura finanziaria e intermediazione creditizia di natura bancaria, quanto piuttosto lo scopo di delineare i diversi percorsi di ricerca e di studio sui temi della finanza d’impresa e dell’intermediazione finanziaria, quali premesse teorico-metodologiche dell’analisi empirica del mercato creditizio della provincia di Caltanissetta, e in particolare del rapporto banca-impresa, condotta nei capitoli successivi.
The kinematics of water masers in the stellar molecular outflow source, IRAS 19134+2131
2004
Using the Very Large Array (VLA) and the Very Long Baseline Array (VLBA), we have observed water maser emission in the proto-planetary nebula candidate IRAS 19134+2131, in which the water maser spectrum has two groups of emission features separated in radial velocity by ∼100 km s^−1. The blue-shifted and red-shifted clusters of maser features are clearly separated spatially by ∼150 mas, indicative of a fast collimated flow. However, not all of the maser features are aligned along the axis of the flow, as is seen in the similar high-velocity water maser source, W43A. Comparing the VLA and VLBA maps of the water maser source, we find 4 maser features that were active for 2 years. Using only V…
Volume III. DUNE far detector technical coordination
2020
The preponderance of matter over antimatter in the early universe, the dynamics of the supernovae that produced the heavy elements necessary for life, and whether protons eventually decay-these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our universe, its current state, and its eventual fate. The Deep Underground Neutrino Experiment (DUNE) is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the st…
