CONFINI E PROGETTO PER LO SPAZIO PUBBLICO A TREVISO
2020
In questa prima parte del Ventunesimo secolo assistiamo alla presenza nelle comunità urbane di attori non istituzionali, soggetti non canonici che, in qualche modo, si presentano sulla scena del governo urbano per sopperire alla mancanza di quelle azioni amministrative che sarebbe invece il dovere naturale degli amministratori della città. Un filo conduttore collega Palermo e Treviso dal 2018, un parallelismo che riunisce rispettivamente l’esperienza di Parco Uditore e Prato della Fiera. Due realtà diverse per storia, geografia, dimensioni, struttura, ma con alcune somiglianze nell’azione svolta da parti delle loro comunità, in uno scenario di riappropriazione e partecipazione attiva, propr…
Eliminating Artificial Boundary Conditions in Time-Dependent Density Functional Theory Using Fourier Contour Deformation
2023
We present an efficient method for propagating the time-dependent Kohn-Sham equations in free space, based on the recently introduced Fourier contour deformation (FCD) approach. For potentials which are constant outside a bounded domain, FCD yields a high-order accurate numerical solution of the time-dependent Schrödinger equation directly in free space, without the need for artificial boundary conditions. Of the many existing artificial boundary condition schemes, FCD is most similar to an exact nonlocal transparent boundary condition, but it works directly on Cartesian grids in any dimension, and runs on top of the fast Fourier transform rather than fast algorithms for the application of …
The effect of Ag, Pb and Bi impurities on grain boundary sliding and intergranular decohesion in Copper
2016
We investigate the changes in grain boundary sliding (GBS) and intergranular decohesion in copper (Cu), due to the inclusion of bismuth (Bi), lead (Pb) and silver (Ag) substitutional impurity atoms at a $\Sigma$5 (0 1 2) symmetric tilt grain boundary (GB), using a first-principles concurrent multiscale approach. We first study the segregation behavior of the impurities by determining the impurity segregation energy in the vicinity of the GB. We find that the energetically preferred sites are on the GB plane. We investigate the intergranular decohesion of Cu by Bi and Pb impurities and compare this to the effect of Ag impurities by considering the work of separation, $W_s$ and the tensile st…
Technology management, networking positions and work/life boundaries among working adult students
2021
In this digitalised world, crossing boundaries between life domains is becoming increasingly easy. We are constantly faced with the need to define whether we are online or offline, and technology management is now an integral part of daily life. Technology management, which is affected by the individual's networking position, has different components: connectivity management, online self-presentation and privacy management. The objective of this study is to explore technology management strategies among working adult students. The study identifies three networking positions: socio-affective enthusiasts, context-contingent pragmatists and pragmatic avoiders. These three groups have specific …
Raccontare e rappresentare le lingue e lo spazio. L'esperienza dell'Atlante Linguistico della Sicilia
2017
La Dialettologia Percettiva, disciplina che si occupa dello studio delle opinioni dei parlanti sulle varietà di lingua, nell'ultimo decennio ha rinnovato i propri fondamenti. Il volume da un lato intende ripercorrere criticamente tali profonde innovazioni, dall'altro propone una serie di modelli originali per l'analisi e l'interpretazione dei dati. Il corpus della ricerca è costituito dalle risposte di circa 900 informatori distribuiti in 60 punti d'inchiesta a tre domande del questionario dell'Atlante Linguistico della Sicilia (ALS) pensate per rilevare la percezione e rappresentazione della differenza linguistica. Una mole imponente di dati che sono stati trattati con un approccio quanti-…
La comprensión e impulso de la Sostenibilidad: un requisito imprescindible para una acción educativa y ciudadana eficaz
2019
Diagnósticos concordantes de la actual situación de emergencia planetaria muestran la necesidad de una urgente transición a sociedades que hagan posible una vida justa y digna al conjunto de seres humanos y a las futuras generaciones, al tiempo que se protege la biodiversidad y se revierte la degradación del medioambiente. Esta problemática ha dado lugar a propuestas con distintas denominaciones -transición a la sostenibilidad, decrecimiento, crecimiento inclusivo… - generando controversias que pueden dificultar el establecimiento de una agenda común para hacer frente a los problemas. Proponemos por ello centrar el debate en analizar las medidas que se consideran necesarias, en particular p…
O możliwościach zastosowania kategorii granicy w analizie zjawiska korupcji
2016
Od lat 90. XX wieku obserwujemy istotny wzrost zainteresowania kwestią korupcji. To również czas ponownego odkrycia problemu granic i pogranicza jako zagadnień centralnych dla procesów towarzyszących człowiekowi pod koniec stulecia. Globalizacja, kolejna fala demokratyzacji oraz upadek ZSRR to zmiany, który stworzyły nowe, strukturalne warunki dla zjawisk korupcyjnych oraz dla przedefiniowania granic politycznych. Pomimo podobieństwa uwarunkowań inspirujących do systematycznej refleksji nad korupcją i granicami, zarówno badania nad korupcją, jak i badania nad granicami zazwyczaj traktowane są jako odrębne obszary badawcze. Możemy jednak wyodrębnić pewne płaszczyzny, na których badania te sp…
The Role of Work-Nonwork Boundary Management in Work Stress Recovery
2016
The aim of the present study conducted among 1,106 Finnish employees was to identify boundary management profiles based on cross-role interruption behaviors from work to nonwork and from nonwork to work. Adopting a person-oriented approach through latent profile analysis, 5 profiles were identified: Work Guardians (21% of the employees), Nonwork Guardians (14%), Integrators (25%), Separators (18%), and an Intermediate Group (22%). We then examined differences between these profiles with respect to recovery experiences ( psychological detachment from work, relaxation, mastery experiences, and control during off-job time) and recovery outcomes (vigor and exhaustion). Work Guardians had the po…

Oxygen Vacancy Formation and Migration within the Antiphase Boundaries in Lanthanum Scandate-Based Oxides: Computational Study.
2022
The study was performed with the financial support from the Latvian Council of Science under the grant agreement LZP-2020/2-0009. Calculations were performed at the HLRS, University of Stuttgart, within the project 12939 DEFTD. The Institute of Solid State Physics, University of Latvia (Latvia), as the Centre of Excellence has received funding from the European Union’s Horizon 2020 Frame-work Programme H2020-WIDESPREAD-01-2016-2017-Teaming Phase2 under grant agreement No. 739508, project CAMART2.
