Correlation patterns from massive phonons in 1+1 dimensional acoustic black holes: A toy model
2018
Transverse excitations in analogue black holes induce a mass like term in the longitudinal mode equation. With a simple toy model we show that correlation functions display a rather rich structure characterized by groups of parallel peaks. For the most part the structure is completely different from that found in the massless case.
Nonperturbative renormalization and O(a)-improvement of the nonsinglet vector current with Nf=2+1 Wilson fermions and tree-level Symanzik improved ga…
2019
In calculating hadronic contributions to precision observables for tests of the Standard Model in lattice QCD, the electromagnetic current plays a central role. Using a Wilson action with O(a) improvement in QCD with Nf flavors, a counterterm must be added to the vector current in order for its on-shell matrix elements to be O(a) improved. In addition, the local vector current, which has support on one lattice site, must be renormalized. At O(a), the breaking of the SU(Nf) symmetry by the quark mass matrix leads to a mixing between the local currents of different quark flavors. We present a nonperturbative calculation of all the required improvement and renormalization constants needed for …
Learner identity in EFL: An analysis of digital texts of identity in higher education
2018
This study explores learner identity (LI) in digital texts of identity (DTI) produced by college learners in English as a foreign language (EFL). In so doing, it aims to shed light on learners’ connections of their learning experiences across time and settings, and their impact on the various learner identities that form their LI. It also intends to elucidate how learners construct powerful learner identities in and through their digital discourses. To this end, 51 DTI were collected and scrutinized, following studies on LI, critical and poststructuralist discourse analysis, and “thematic” and “dialogic/performative” analysis within narrative research. Learners established connections betwe…
The use of EduBlog in initial teachers training: an experience of a teaching innovation project
2020
Digital technologies are central elements of today's society. In this context to achieve an adequate degree of development of Digital Competence for professional performance is essential, as well as for life in society and the exercise of citizenship. Higher Education must actively contribute to develop Digital Competence, training students to effectively use digital technologies. That need is exacerbated in the case of initial teacher training, not only because of the progress towards a digitalized school, but also because of the fundamental role in the training of future generations. With the aim of promoting the development of Digital Teaching Competence, this paper presents an innovatio…
Sharing Perspectives in Virtual Interaction: Review of Methods of Analysis
2003
The aim of this paper is to describe the methodological solutions made in the studies that are part of the SHAPE research project. The SHAPE project investigates the quality and nature of virtual interaction in a higher education context. The study aims to find out variables that mediate the process of collaboration, particularly the emerging processes of sharing and constructing perspectives in virtual interaction. For conducting these studies we have developed various methods and models of analysis in order to gain better understanding of the process of collaboration in virtual interaction. In this paper, we will make a review of some of the SHAPE analysis methods used in the series of ou…
Supporting teachers' needs within and through E-learning systems
2014
These days more and more digital learning and teaching opportunities emerge into the world of higher education. In this upcoming project which is described in this paper, the teachers' needs, especially their teaching motivation will be regarded. This project is part of a bigger project, where several different faculties will work together. This combination of faculties is beneficial for topics like these, because the approach combines pedagogical and technical knowledge. This topic regarding teachers' needs deals with the initial and ongoing motivation as well as behavior and attitudes toward current or upcoming ICT systems for education. The main aspect of the project is to specify issues…
The changing role of students' representation in Poland: an historical appraisal
2014
Student representation in Poland has a relatively short but turbulent history. This article offers an historical appraisal of the development of student representation at the national level in the context of rapid and deep structural changes in Polish higher education. Based on a desktop analysis of official documentation, legislation, ideological declarations and background (first-hand) information provided by student leaders, the article reconstructs the establishment of the first independent self-governing student organisation in the country. In so doing, the paper pays particular attention to the emergence, institutionalisation as well as legitimacy challenges facing student bodies eith…

La història digital: una certa idea i algunes il·lustracions
2013
A les darreres dècades, les noves tecnologies han fet que els historiadors reconsiderin les formes com investiguen, escriuen i difonen el seu treball. La pretensió d’aquest text és esbossar un marc general al voltant del que significa la història digital, proposant una distinció entre la «història a l’era digital» i «la història digital»: entre els estudiosos que utilitzen certs recursos i eines digitals (processadors de textos, correu electrònic, catàlegs, etcètera) i els acadèmics que desenvolupen una nova comprensió de la història, compromesos amb el paper que les noves tecnologies digitals poden assolir dins l’estudi del passat. Aquest assaig analitza ambdues perspectives, presentant un…
The New European Wind Atlas Model Chain
2020
The New European Wind Atlas (NEWA), the largest European project on wind resource assessment technology, has developed mesoscale-to-microscale wind atlas and site assessment methodologies alongside a validation strategy that leverages data from large field experiments as well as wind resource campaigns from industry through a formal verification and validation process. A probabilistic wind atlas approach, based on a multi-physics ensemble, provides means to quantify the uncertainty associated to the mesoscale configuration. Offline meso-micro coupling has been adopted to provide a modular approach for microscale models of different fidelities to share common mesoscale input data. An opensou…
