Random walk approximation of BSDEs with H{\"o}lder continuous terminal condition

2018

In this paper, we consider the random walk approximation of the solution of a Markovian BSDE whose terminal condition is a locally Hölder continuous function of the Brownian motion. We state the rate of the L2-convergence of the approximated solution to the true one. The proof relies in part on growth and smoothness properties of the solution u of the associated PDE. Here we improve existing results by showing some properties of the second derivative of u in space. peerReviewed

Radiative and dynamic effects of absorbing aerosol particles over the Pearl River Delta, China

2008

Abstract Results are reported from a ground-based measurement campaign conducted in a highly polluted region in southeast of China in October–November 2004. The experiment focused on absorbing aerosol particles and their effects on the solar radiation field and local meteorology. A Raman lidar in conjunction with Sun photometer data measured profiles of particle extinction; ground-based in situ data of aerosol optical properties were collected by nephelometer and absorption photometer. Exceptionally high values of aerosol optical depth of up to 1.5 were observed. The measurements were input to a radiative transfer model, which simulated high solar radiative forcing values for the aerosol pa…

Classifying Economics for the Common Good: Connecting Sustainable Development Goals to JEL Codes

2020

How does economics research help in solving societal challenges? This brief note sheds additional light on this question by providing ways to connect Journal of Economic Literature (JEL) codes and Sustainable Development Goals (SDGs) of the United Nations. These simple linkages illustrate that the themes of SDGs have corresponding JEL classification codes. As the mappings presented here are necessarily imperfect and incomplete, there is plenty of room for improvements. In an ideal world, there would be a JEL classification system for SDGs, a separate JEL code for each of the 17 SDGs.

epiModel: A system to build automatically systems of differential equations of compartmental type-epidemiological models

2011

In this paper we describe epiModel, a code developed in Mathematica that facilitates the building of systems of differential equations corresponding to type-epidemiological linear or quadratic models whose characteristics are defined in text files following an easy syntax. It includes the possibility of obtaining the equations of models involving age and/or sex groups. © 2011.

A New Algorithm for the Retrieval of Sun Induced Chlorophyll Fluorescence of Water Bodies Exploiting the Detailed Spectral Shape of Water-Leaving Rad…

2021

Sun induced chlorophyll fluorescence (SICF) emitted by phytoplankton provides considerable insights into the vital role of the carbon productivity of the earth’s aquatic ecosystems. However, the SICF signal leaving a water body is highly affected by the high spectral variability of its optically active constituents. To disentangle the SICF emission from the water-leaving radiance, a new high spectral resolution retrieval algorithm is presented, which significantly improves the fluorescence line height (FLH) method commonly used so far. The proposed algorithm retrieves the reflectance without SICF contribution by the extrapolation of the reflectance from the adjacent regions. Then, the SICF …

Tutela e sicurezza del lavoro tra centro e periferia: la sicurezza sui luoghi di lavoro

2013

Il saggio prende in esame la complessa questione del riparto di competenze tra Stato e Regioni alla luce del Titolo V della Costituzione in materia di salute e sicurezza sui luoghi di lavoro. Il riparto di competenze tra centro e periferia è stato oggetto di una limitata analisi da parte della dottrina e della giurisprudenza, che si sono concentrate in particolare sulla disciplina del mercato del lavoro. L’Autore descrive un sistema multilivello, caratterizzato dalla compresenza di fonti nazionali e regionali, della contrattazione collettiva, nonché di codici di condotta. Sulla scorta di una ricostruzione del quadro normativo e dei percorsi della giurisprudenza, il saggio propone una lettur…

The essay examines the complex issue of the division of powers between the State and the Regions according to Title V of the Constitution concerning health and safety at workplace. This division between the center and the periphery has been subject to a limited review by doctrine and jurisprudence expecially focusing on the regulation of labour market. The Author describes a multilevel system characterized by the presence of national and regional sources collective bargaining and codes of conduct. On the basis of a reconstruction of the regulatory framework and the judicial statements the paper proposes a dynamic reading of the relationship between center and periphery in which the axis of the system remains however anchored to the national jurisdiction along with important regulatory issues left to the regional legislation.Settore IUS/07 - Diritto Del Lavoro

Sensitivity of shortwave radiative fluxes to the vertical distribution of aerosol single scattering albedo in the presence of a desert dust layer

2010

Abstract The aim of this work is to quantify the sensitivity of shortwave radiative fluxes to changes in the vertical distribution of aerosol absorption, taken into account through the aerosol Single Scattering Albedo (SSA). The case study represents a real atmospheric situation with a desert dust layer (DDL) in the mid troposphere over an urban Boundary Layer (BL) observed at Rome on 20 June 2007. A moderately high aerosol optical depth (AOD), 0.292 at 550 nm, and low Angstrom exponent of 0.30 were measured. The observed case was reconstructed with a radiative transfer model, in which the SSA of the boundary layer aerosols was varied from that of a highly absorbing aerosol type (urban) to …
