The media competence as a challenge for educommunication : tools of evaluation

2014

RESUMEN: Para mejorar el aprendizaje, los avances tecnológicos ponen a disposición de los agentes educativos recursos emergentes, los cuales requieren del desarrollo de competencias o destrezas básicas por parte de los estudiantes y suponen un reto para toda la comunidad educativa. En este contexto, la competencia mediática se convierte en la clave para fomentar un uso responsable, eficiente y democrático de los recursos mediáticos por parte de los ciudadanos. Se presentan aquí los resultados de un proyecto de investigación realizado en España, en el que se han diseñado diversos instrumentos de evaluación de la competencia mediática de estudiantes, profesorado, así como de padres y madres. …

Computational Intelligence and Citizen Communication in the Smart City

2016

Information and communication are at the core of the intelligent city of tomorrow, and the key components of a smart city cannot prescind from data exchanges and interconnectedness. Citizen communication is an integral part of the smart city’s development plans: freedom of information and involvement in collective decisions, e-democracy and decision-making feedback can be greatly enhanced in an intelligent city, and, among other smart city components, foster a new era of participation and wise decisions. In this contribution we describe the methodologies that can be implemented in order to correctly develop automatic recognition systems for citizen communication, paying special attention to…

A Realistic Proposal for the Observation of Zeno Phenomena in the Dynamics of Trapped Ions

2001

A realistic experimental scheme for the observation of a continuous measurement Quantum Zeno Effect in the contest of single trapped ions is proposed. Our method relies on the nonlinearities characterizing the ionic Rabi frequency far from the Lamb-Dicke regime.

Solution processable high band gap hosts based on carbazole functionalized cyclic phosphazene cores for application in organic light‐emitting diodes

2011

A new class of solution processable dendrimers based on cyclic phosphazene (CP) cores have been prepared and used as host materials for blue and green organic light emitting diodes (OLEDs). The dendrimers are prepared in high yield from minimal step reactions, are soluble in common solvents for solution processing, are amorphous, and have excellent thermal properties necessary for application in OLEDs. OLED efficiencies of 10.3 cd/A (4.2 Im/W) and 35.3 cd/A (33.5 Im/W) were achieved using commercially available Flrpic and Ir(mppy) 3 as blue and green phosphorescent emitters, respectively. These efficiencies were 2x higher than control devices prepared using poly(N-vinylcarbazole), the most …

Chebyshev’s Method on Projective Fluids

2020

We demonstrate the acceleration potential of the Chebyshev semi-iterative approach for fluid simulations in Projective Dynamics. The Chebyshev approach has been successfully tested for deformable bodies, where the dynamical system behaves relatively linearly, even though Projective Dynamics, in general, is fundamentally nonlinear. The results for more complex constraints, like fluids, with a particular nonlinear dynamical system, remained unknown so far. We follow a method describing particle-based fluids in Projective Dynamics while replacing the Conjugate Gradient solver with Chebyshev’s method. Our results show that Chebyshev’s method can be successfully applied to fluids and potentially…

Joseph Conrad-Korzeniowski, czyli polska dusza w literaturze angielskiej

2016

Joseph Conrad wniósł do literatury angielskiej prawdziwie polską duszę i fantazję. Ostatni z polskich romantyków, jak sam siebie nazwał, wprowadził do światowej literatury polskie dylematy, rozterki i wątpliwości, a także tęsknoty i pragnienia. Conrad przeniósł polskie doświadczenie na poziom uniwersalny i takim owo doświadczenie również uczynił. Rozmaite relacje współczesnych ukazują, jak niejednokrotnie trudno było odnaleźć się Polakowi w anglosaskiej rzeczywistości, i z jakimi przeciwnościami musiał się zmierzyć.

Analyses of known and new types of polyhalogenated aromatic substances in oven ash from recycled aluminium production

2003

Abstract Persistent aromatic bromine, chlorine and mixed chlorine-bromine compounds were analysed from recycled aluminium smelter (ALS) ashes to explore the impact of brominated flame retardants (BFR) on their formation. Polybrominated diphenyl ethers (PBDE) were the most abundant original BFRs found. Induction furnace ash contained tetra- to octa-BDEs about 2000 ng g −1 in similar congener ratios as the original scrap, but contents of nona- and deca-BDEs were only 25 and 5 ng g −1 indicating their significant degradation in ALS process. In the most non-polar fraction, PCB levels and profiles were similar as earlier ALS ash samples in 1990s. The highest PCB level measured was that of deca-C…

Isobaric Vapor−Liquid Equilibrium of Binary Mixtures of 1-Butanol + Chlorobenzene and 2-Butanol + Chlorobenzene at 20 and 100 kPa

1997

Isobaric vapor−liquid equilibria were obtained for 1-butanol + chlorobenzene and for 2-butanol + chlorobenzene systems at 20 and 100 kPa using a dynamic still. The experimental error in temperature was ±0.1 K, in pressure ±0.01 kPa and ±0.1 kPa for the experiments carried out at 20 and 100 kPa, respectively, and in liquid and vapor composition ±0.001. The two systems satisfy the point-to-point thermodynamic consistency test. Both systems show a positive deviation from ideality. The data were correlated with the Wilson equation.

The implementation of global ranking rules within countries in transition and their unintended perverted effects

2013

PurposeThe aim of this paper is to focus on the adverse consequences, mainly the “naturalisation” of global indicators and principles that may lead to defective national rules that may harm the local academic system, and the manipulations that might be drown up among the academic staff and public.Design/methodology/approachThe theoretical issues are illustrated by the outcomes in Romania particularly as a consequence of the application of the Educational Law since January 2011.FindingsWhen the global ranking's rules are implemented into national environments, mainly in countries under transition, some perverted effects appear and accompany the fruitful results.Originality/valueThe passage f…
