Orthographic input and phonological representations in learners of Chinese as a foreign language. [PDF]

open access: yes, 2006
This paper provides evidence that the second language orthographic input affects the mental representations of L2 phonology in instructed beginner L2 learners. Previous research has shown that orthographic representations affect monolinguals' performance

Representationer av aids

open access: yesKulturella Perspektiv, 2000
From this perspective our knowledge of the world is mediated through representations provided by language. The text interpellates the subject, by way of making her a specific subject with a specific social position.

Representation is representation of similarities

open access: yesBehavioral and Brain Sciences, 1998
Advanced perceptual systems are faced with the problem of securing a principled (ideally, veridical) relationship between the world and its internal representation. I propose a unified approach to visual representation, addressing the need for superordinate and basic-level categorization and for the identification of specific instances of familiar

Black Box Galois Representations [PDF]

open access: yes, 2018
We develop methods to study $2$-dimensional $2$-adic Galois representations $\rho$ of the absolute Galois group of a number field $K$, unramified outside a known finite set of primes $S$ of $K$, which are presented as Black Box representations, where we ...

Representations of the cyclically symmetric q-deformed algebra $so_q(3)$

open access: yes, 1998
An algebra homomorphism $\psi$ from the nonstandard q-deformed (cyclically symmetric) algebra $U_q(so_3)$ to the extension ${\hat U}_q(sl_2)$ of the Hopf algebra $U_q(sl_2)$ is constructed.

Naturality and Induced Representations [PDF]

open access: yes, 2000
We show that induction of covariant representations for C*-dynamical systems is natural in the sense that it gives a natural transformation between certain crossed-product functors.

Underestimated Cost of Targeted Attacks on Complex Networks

open access: yesComplexity, 2018
The robustness of complex networks under targeted attacks is deeply connected to the resilience of complex systems, which is defined as the ability to make appropriate response to the attack. In this paper, we study robustness of complex networks under a

Trekkers in the High-altitude Pyrenees: What Representation for Which Practice?

open access: yesRevue de Géographie Alpine, 2021
This article paints a portrait of trekkers in the high-altitude Pyrenees. Sometimes depicted as different from the trekkers of the Alps, this image may stem from a different imaginary construct, be it in terms of a particular representation of the high ...

Floquet Energies and Quantum Hall Effect in a Periodic Potential

open access: yes, 1998
The Quantum Hall Effect for free electrons in external periodic field is discussed without using the linear response approximation. We find that the Hall conductivity is related in a simple way to Floquet energies (associated to the Schroedinger equation

Induced PUA representations and selection rules [PDF]

open access: yes, 1978
Well known properties of induced unitary representations are generalised for induced PUA representations. They are applied to obtain an expression for the multiplicities in the Clebsch-Gordon series of induced PUA representations.
