Diritti umani in emergenza. Dialoghi sulla disabilità ai tempi del Covid-19
No full textFenomeno dall'altissimo costo sociale in termini di vite umane e di garanzia del diritto alla salute fisica e psichica, la pandemia da Covid-19 si è rivelata uno "specchio" della tenuta dei principi di eguaglianza e non discriminazione. Ha infatti amplificato le diseguaglianze sociali e, al contempo, ne ha generate di nuove. Tra i soggetti che più hanno subìto l'impatto negativo della pandemia sulle loro vite, figurano le persone con disabilità e quelle anziane non autosufficienti, i cui diritti umani sono stati violati con più frequenza e maggiore facilità, per la presenza di barriere istituzionali, ambientali e attitudinali, in gran parte diffuse già prima della pandemia, e che quest'ultima ha esacerbato. All'interno del volume, esperti del mondo della ricerca e dell'associazionismo rivolgono la propria attenzione al contesto nazionale, riflettendo sull'impatto prodotto dalla pandemia da Covid-19 sui diritti umani delle persone con disabilità, incentrando la propria analisi su stigma e istituzionalizzazione, accessibilità, discriminazioni multiple delle donne con disabilità, caregiving

STREAmS-2.0: Supersonic turbulent accelerated Navier-Stokes solver version 2.0
No full textWe present STREAmS-2.0, an updated version of the flow solver STREAmS, first introduced in Bernardini et al. (2021) [1]. STREAmS-2.0 has an object-oriented design which separates the physics equations from the specific back-end, making the code more suitable for future expansions, such as porting to novel computing architectures or implementation of additional flow physics. Similarly to the previous version, STREAmS-2.0 supports NVIDIA-GPU and CPU back-ends. Additionally, this version features improvements of the input/output data management, new energy and entropy preserving schemes for the discretization of the convective fluxes, recycling/rescaling inflow boundary condition, and a model for thermally perfect gases with variable specific heats. New version program summary: Program Title: STREAmS CPC Library link to program files: https://doi.org/10.17632/hdcgjpzr3y.2 Developer's repository link: https://github.com/STREAmS-CFD/STREAmS-2 Licensing provisions: GPLv3 Programming language: Fortran, CUDA Journal reference of previous version: M. Bernardini, D. Modesti, F. Salvadore, and S. Pirozzoli. STREAmS: a high-fidelity accelerated solver for direct numerical simulation of compressible turbulent flows. Comput. Phys. Commun. 263 (2021) 107906. Does the new version supersede the previous version?: Yes. Reasons for the new version: New code structure and release of new features. Summary of revisions: • The original solver [1] has been rewritten following an object-oriented design implemented through Fortran derived types that include variables and type bound procedures. The new software architecture has been designed to increase modularity and extensibility of the code, allowing users to add new back-ends and physics equations while maintaining the same code structure. This allows users to reuse portions of the code that are independent of the physics equations, the back-end, or both. The layer of computing procedures maintains a lean structure that can be highly optimized with respect to the implemented back-end. • Input handling is now based on the classic.ini format improving both user readability and input data management. • A family of new kinetic energy and entropy preserving schemes (KEEP) are now available and can be selected for stable, non-dissipative and accurate spatial discretization of the convective terms of the Navier–Stokes equations in smooth flow regions [2]. Concerning the shock-capturing flux, the improved low-dissipative WENO-Z scheme proposed by [3] is now available. • New inflow boundary conditions based on the recycling/rescale approach [4] have been implemented for the simulation of spatially evolving compressible turbulent boundary layers. Moreover, a new inflow condition based on the solution of the compressible Blasius equation is available to take into account the case of laminar boundary layers. • The constitutive relations have been generalized to take into account thermally perfect gases with variable specific heats, approximated with polynomial functions of the temperature that can be specified by the user [5]. • A new stretching function has been implemented to improve the distribution of grid nodes for the computation of wall-bounded turbulent flows. The formulation blends uniform near-wall spacing with uniform resolution in terms of Kolmogorov units in the outer wall layer, guaranteeing accuracy with higher computational efficiency [6]. Nature of problem: The code solves the compressible Navier–Stokes equations in Cartesian coordinates for a thermally perfect gas. The solver is designed for direct numerical simulation (DNS) of compressible supersonic turbulent boundary layers and various canonical configurations are supported, including turbulent channel flow, laminar and turbulent boundary layer and shock-wave/boundary layer interaction. Solution method: The equations are discretized using high-order finite difference approximations with hybrid low-dissipative/shock-capturing capabilities and the time advancement is performed using a Runge–Kutta scheme.

Diritti umani in emergenza: un’introduzione
No full textLe persone con disabilità, quelle anziane non autosufficienti e i/le loro caregivers sono alcuni tra i soggetti che hanno rivelato una maggiore vulnerabilità alla pandemia: i loro diritti umani sono infatti stati violati con più frequenza e con maggiore facilità, a causa di una discriminazione di tipo strutturale, già esistente, che l’emergenza di questi mesi ha concorso a esacerbare. La vulnerabilità in questione è di tipo patogeno e come tale richiede che sia posta un’attenzione particolare ai soggetti, ai luoghi e ai processi che concorrono a crearla
Corpora in Translator Education: An Introduction
No full textThe use of corpora to verify how words are used in context can be particularly useful in areas of languages for special purposes (LSPs) and terminology. The very possibility of examining terms in texts that deal with the subject matter under discussion makes it easier for the terminologist - and also the translator - to understand the concepts behind the terms used. The chapter focuses on efforts made to find and use text corpora in English and Portuguese to further terminology work in various areas, the problems that arise and how they can, or cannot, be solved. Collecting parallel corpora means acquiring both original texts and their translations in electronic form. Comparable corpora are ‘collections of individual monolingual corpora’ which use ‘the same or similar sampling procedures and categories for each language but contain completely different texts’
A WaCky introduction
No full textIn this article we discuss four different ways of using the Web as a corpus, focusing particularly on those taking the lion share of this volume of working papers: the Web as a “corpus shop”, and the “mega-corpus/mini-Web” as a new object. The latter in particular will be described in some detail, and special attention will be paid to the design of this resource and the challenges posed by its development

Promoting international cooperation among small firms for innovative strategies
No full textThis chapter is focused on the analysis of inter-firm cooperation to promote innovative actions. Nowadays the European Commission supports small and medium-sized firm relationships because these firms have insufficient resources and capabilities to implement such relationships otherwise. Innovation activities are crucial elements of small firms’ economic performance and the development of networks among firms to share complementary relations can stimulate the development of less-favored regions. Bernardini Papalia and Bertarelli study theoretically and empirically a small firm’s decision to participate in the initiatives where public authorities or associations of firms promote collaboration with other small firms. Bernardini Papalia and Bertarelli develop a model to analyze the creation of contacts among small firms within a search theory framework. The range of contacts for which the firm accepts to participate to these initiatives is influenced by the probability to contact a firm sharing a common project of collaboration. In line with the theoretical model, the empirical study is concentrated on the estimation of the probability to find contacts for the representative firm. A pseudopanel framework is used to estimate Poisson models from repeated cross-sections.
The rareness of contacts between firms in a given instant of time suggests that data may be described by a Poisson model related to different projects and firms’ profiles; the latter ones are modeled through cohort fixed effects
