Confidencialidad y protección de datos en la mediación en la Unión Europea
2018
La mediación, su confidencialidad y la protección de datos son muy importantes en el siglo XXI y objeto autónomo de muchos estudios. No obstante, en raras ocasiones se analiza la conjunción de estos elementos y las muchas exigencias jurídicas que se derivan. Se efectúan propuestas de mejora en la normativa y en los marcos contractuales de la mediación. Primero, el estudio analiza la confidencialidad y su interactuación con la protección de datos. Se analizan los sujetos obligados, el alcance de las obligaciones, su duración y garantías así como, finalmente las excepciones y restricciones a la confidencialidad. La segunda aproximación se hace desde la protección de datos, pues toda mediación…
La "normatività" tra etica e metafisica
2017
The Author’s aim is to highlight the limits of monist metaphysics which underpin the paradigm of Secular Humanism. In fact, all forms of monism consider good and evil either as internal momentums to the logic of development of the world, or as mere illusions within the evolutionary process. Can tragedies as the Holocaust be interpreted by such a monistic approach? The distinction between ‘polar opposition’ and ‘logic of contradiction’ is introduced by Romano Guardini. This is based on a creationistic metaphysic and it is useful to show that our practical-moral investigation is legitimated only by a theist approach. By considering good and evil as two aspect with mutual implications, monisti…
Correcting the effect of stellar spots on ARIEL transmission spectra
2020
The goal of this study is to assess the impact of the stellar spots on the extraction of the planetary transmission spectra observed by ARIEL. We develop a method to model the stellar spectrum of a star in the presence of spots by using the out-of-transit observations. It is based on a chi squared minimization procedure of the out-of-transit spectrum on a grid of stellar spectra with different sizes and temperatures of the spots. The approach allows us also to study the temporal evolution of the spots when comparing stellar spectra observed at different epochs. We also present a method to correct the transit depth variations due to non-occulted stellar spots and estimate the error we introd…
The GAPS Programme with HARPS-N at TNG: . Atmospheric Rossiter-McLaughlin effect and improved parameters of KELT-9b
2019
In the framework of the GAPS project, we observed the planet-hosting star KELT-9 (A-type star, VsinI$\sim$110 km/s) with the HARPS-N spectrograph at the TNG. In this work we analyse the spectra and the extracted radial velocities (RVs), to constrain the physical parameters of the system and to detect the planetary atmosphere of KELT-9b. We extracted from the high-resolution optical spectra the mean stellar line profiles with an analysis based on the Least Square Deconvolution technique. Then, we computed the stellar RVs with a method optimized for fast rotators, by fitting the mean stellar line profile with a purely rotational profile instead of using a Gaussian function. The new spectra an…
IL SINDACO DEL RIONE SANITÀ – MIT WŁOSKIEGO GUAPPO OCZAMI LUIGIEGO PIRANDELLA
2015
The article proposes an analysis of one of the main plays written by Eduardo De Filippo, Il sindaco del rione Sanita, considered here in a wide context: the literary and artistic representation of Neapolitan criminality. Understood by a part of the critics and later by sociological studies focused on the camorra as the “personification of the myth” of the guappo, often in opposition to the parodistic and disenchanted version of the character offered by Raffaele Viviani, Eduardo’s Sindaco actually maintains with this topos an extensively ambiguous connection. In this essay, using the proper methods of textual analysis in a dialogue with some contributions taken from historiography and sociol…
Could CoRoT-7b and Kepler-10b be remnants of evaporated gas or ice giants?
2009
We present thermal mass loss calculations over evolutionary time scales for the investigation if the smallest transiting rocky exoplanets CoRoT-7b (∼1.68REarth) and Kepler-10b (∼1.416REarth) could be remnants of an initially more massive hydrogen-rich gas giant or a hot Neptune-class exoplanet. We apply a thermal mass loss formula which yields results that are comparable to hydrodynamic loss models. Our approach considers the effect of the Roche lobe, realistic heating efficiencies and a radius scaling law derived from observations of hot Jupiters. We study the influence of the mean planetary density on the thermal mass loss by placing hypothetical exoplanets with the characteristics of Jup…
ON THE “SOLAR SYSTEM SMALL BODIES” ASTROPLATE PROJECT OF THE UKRAINIAN VIRTUAL OBSERVATORY
2019
The UkrVO Joint Digital Archive of astro- plates and the newest digitized data processing services al- lowed us to form a new approach for the creation of catalogs of astrometric and photometric characteristics of the Solar System bodies. Given this, the main goal of this approach was not only to complete the processing with the best possi- ble accuracy of high-quality and unprocessed earlier photo- graphic observations of the Solar System bodies but also to find new original data from these observations. As a result, more than 6,500 new astrometric positions and stellar magnitudes of asteroids, and 3,036 positions of outer planets (Pluto, Uranus, Neptune, Saturn, Jupiter) and their satelli…
La crisis gremial y los problemas de la sedería valenciana (finales del siglo XVIII y principios del siglo XIX)
1992
La reforma del sistema gremial alcanza una de sus medidas más radicales con la abolición de los gremios de torcedores de seda en 1793. En estas páginas se analiza la medida abolicionista en el marco general de los problemas de la sedería valenciana. En la misma, la hilatura, de la que el torcido es su fase superior y última, había llegado a constituirse en un cuello de botella que comprometía su futuro. En los años aquí contemplados, se proponen y ensayan diversas alternativas que solucionen las disfunciones que generaba la peculiar división del trabajo que obraba en la sedería. La no implicación del capital comercial de la ciudad en la necesaria reconversión de la hilatura será un factor c…
M Stars in the TW Hya Association: Stellar X-rays and Disk Dissipation
2016
To investigate the potential connection between the intense X-ray emission from young, low-mass stars and the lifetimes of their circumstellar, planet-forming disks, we have compiled the X-ray luminosities ($L_X$) of M stars in the $\sim$8 Myr-old TW Hya Association (TWA) for which X-ray data are presently available. Our investigation includes analysis of archival Chandra data for the TWA binary systems TWA 8, 9, and 13. Although our study suffers from poor statistics for stars later than M3, we find a trend of decreasing $L_X/L_{bol}$ with decreasing $T_{eff}$ for TWA M stars wherein the earliest-type (M0--M2) stars cluster near $\log{(L_X/L_{bol})} \approx -3.0$ and then $\log{(L_X/L_{bol…
Methane line parameters in the HITRAN2012 database
2013
International audience; The compilation of methane molecular line parameters was updated to include new global analyses and measurements for 12CH4, 13CH4 and 12CH3D. Over 70% of the methane parameters in HITRAN2008 were replaced; existing parameters retained were the microwave lines and the Dyad of 13CH4 near 7 μm and ν6 of 13CH3D near 8.7 μm, 12CH3D (7-4076 cm-1), hot bands of 12CH4 (1887-3370 cm-1) and normal sample CH4 (4800-5550 cm-1 and 8000-9200 cm-1). With a minimum intensity at 296 K in units of cm-1/(molecule cm-2) set to 10-37 for the far-IR and 10-29 for the mid- and near-IR, the methane database increased from 290,091 lines in HITRAN2008 to 468,013 lines, and three-fourths of th…
