IL BENE DELLA DIGNITÀ UMANA IN SOCCORSO DELLA LEGGE MERLIN? : SULLA SENTENZA 141/2019 DELLA CORTE COSTITUZIONALE IN MATERIA DI FAVOREGGIAMENTO E RECL…
2019
Con la sentenza 141/2019 la Corte costituzionale ha dichiarato non fondata la questione di legittimità costituzionale dei reati di “reclutamento” e di “favoreggiamento” della prostituzione, proposta dalla Corte d’Appello di Bari. A partire dalla vicenda oggetto di giudizio, e dopo una preliminare indagine sui modelli di regolamentazione normativa della prostituzione volontaria e sui dubbi di legittimità costituzionale espressi dalla ordinanza di remissione, ci si sofferma su taluni aspetti critici della decisione. Nella prospettiva dell’Autore, la scelta di prostituirsi ha una inscindibile doppia natura (sessuale ed economica) e dunque una plurima copertura costituzionale; discutibili sono …

Are we who we cite? : on epistemological injustices, citing practices, and #metoo in academia
2019
The #metoo movement reaching academia and Applied Linguistics creates a need for discussion on how we as scholars react to oppressive ideologies and behaviors in our community. However, this is not merely a question of processing cases of sexual harassment and assault. More deeply, we need conversations on who we do and do not know, read, and cite, and how to make our field more epistemologically equitable. This article hopes to elicit comments, reactions, and dialogue. nonPeerReviewed
Non-Markovian Dynamics of a Qubit Due to Single-Photon Scattering in a Waveguide
2018
We investigate the open dynamics of a qubit due to scattering of a single photon in an infinite or semi-infinite waveguide. Through an exact solution of the time-dependent multi-photon scattering problem, we find the qubit's dynamical map. Tools of open quantum systems theory allow us then to discuss the general features of this map, find the corresponding non-Linbladian master equation, and assess in a rigorous way its non-Markovian nature. The qubit dynamics has distinctive features that, in particular, do not occur in emission processes. Two fundamental sources of non-Markovianity are present: the finite width of the photon wavepacket and the time delay for propagation between the qubit …
Speeches About Men and Women in Technical Education: Between Reproduction and Transformation. A Study Located in Two Argentinian Provinces
2020
La formación técnica en Argentina ha sido un ámbito históricamente masculinizado. Ante el incremento de la matrícula femenina y la visibilización y demandas sociales respecto de las desigualdades de género, nos preguntamos, de qué manera las instituciones de ETP favorecen el reconocimiento y la participación con miras a la justicia social. Este trabajo analiza discursos sobre las desigualdades entre varones y mujeres (en interseccionalidad con otras) que circulan en 12 instituciones de educación técnico profesional en dos provincias argentinas (Neuquén y Mendoza), y sobre los dispositivos de acompañamiento a la escolaridad y articulación con el trabajo que allí se construyen. Desplegamos un…
Removing the saturation assumption in Bank-Weiser error estimator analysis in dimension three
2020
International audience; We provide a new argument proving the reliability of the Bank-Weiser estimator for Lagrange piecewise linear finite elements in both dimension two and three. The extension to dimension three constitutes the main novelty of our study. In addition, we present a numerical comparison of the Bank-Weiser and residual estimators for a three-dimensional test case.

Controlled turbulence regime of electron cyclotron resonance ion source for improved multicharged ion performance
2020
Fundamental studies of excitation and non-linear evolution of kinetic instabilities of strongly nonequlibrium hot plasmas confined in open magnetic traps suggest new opportunities for fine-tuning of conventional electron cyclotron resonance (ECR) ion sources. These devices are widely used for the production of particle beams of high charge state ions. Operating the ion source in controlled turbulence regime allows increasing the absorbed power density and therefore the volumetric plasma energy content in the dense part of the discharge surrounded by the ECR surface, which leads to enhanced beam currents of high charge state ions. We report experiments at the ECR ion source at the JYFL accel…
Effect of space charge on the negative oxygen flux during reactive sputtering
2017
Negative ions often play a distinctive role in the phase formation during reactive sputter deposition. The path of these high energetic ions is often assumed to be straight. In this paper, it is shown that in the context of reactive magnetron sputtering space charge effects are decisive for the energetic negative ion trajectories. To investigate the effect of space charge spreading, reactive magnetron sputter experiments were performed in compound mode with target materials that are expected to have a high secondary ion emission yield (MgO and CeO2). By the combination of energy flux measurements, and simulations, a quantitative value for the negative oxygen ion yield can be derived.
Determination of an empirical law of aluminium and magnesium alloys absorption coefficient during Nd :YAG laser interaction
2007
International audience; Welding laser modelling requires knowledge about relative changes of many thermo-physical parameters involved in the interaction. The absorptivity of the material is one of the most important. In this study, experimental measurements of absorptivity with an integrating sphere on two alloys (aluminium and magnesium) were made. These results were compared with an analytical calculation that takes into account the trapping of the beam by multiple reflections inside the keyhole. Based on a statistical method, an empirical law is proposed connecting absorptivity with the peak power of the laser and the duration of interaction. During the interaction, two distinct phenomen…
