A nonhomogeneous nonlocal elasticity model
2006
Nonlocal elasticity with nonhomogeneous elastic moduli and internal length is addressed within a thermodynamic framework suitable to cope with continuum nonlocality. The Clausius–Duhem inequality, enriched by the energy residual, is used to derive the state equations and all other thermodynamic restrictions upon the constitutive equations. A phenomenological nonhomogeneous nonlocal (strain difference-dependent) elasticity model is proposed, in which the stress is the sum of two contributions, local and nonlocal, respectively governed by the standard elastic moduli tensor and the (symmetric positive-definite) nonlocal stiffness tensor. The inhomogeneities of the elastic moduli and of the int…

Antennas for the detection of radio emission pulses from cosmic-ray induced air showers at the Pierre Auger Observatory.
2012
The Pierre Auger Observatory is exploring the potential of the radio detection technique to study extensive air showers induced by ultra-high energy cosmic rays. The Auger Engineering Radio Array (AERA) addresses both technological and scientific aspects of the radio technique. A first phase of AERA has been operating since September 2010 with detector stations observing radio signals at frequencies between 30 and 80 MHz. In this paper we present comparative studies to identify and optimize the antenna design for the final configuration of AERA consisting of 160 individual radio detector stations. The transient nature of the air shower signal requires a detailed description of the antenna s…
El mito de Icario en la General estoria de Alfonso X
2013
This article studies the myth of Icarus as it is translated in the first part of Alfonso X's General estoria. Its analysis highlights aspects that are usually found in the mythographical episodes of the Alfonsine estoria, particularly linked with its possible sources and its internal characteristics. The latter ones are defined by the anonymity of the quote and an evident moral intention. Regarding the sources, if it is known that the mythography gets to the Alfonsine text through two paths, the gloss in the manuscripts and a mythographical work, the exact source or sources used by Alfonsine historians are still unidentified. I have begun searching where the elements that are found in no pr…
Boundary communication: how smartphone use after hours is associated with work-life conflict and organizational identification
2020
This study investigates how boundary communication mediates the effects of smartphone use for work after hours on work-life conflict and organizational identification. It draws upon boundary theory, work-family border theory, and a structurational view of organizational identification. The research site was a large Scandinavian company operating in the telecommunications industry, with 367 employees responding to a survey at two time periods. In contrast to many studies, the use of information and communication technologies (here, smartphones) for after-hours work was not associated with work-life conflict, but was positively associated with organizational identification. However, communica…
Oppilaiden kaikupuheen tehtävät kielellisesti epäsymmetrisissä luokkahuonekeskusteluissa
2017
Repeating the words of the conversational partners gives the persons with restricted communicative abilities a possibility for taking an active part in and exerting some control in the conversational interaction. Earlier research has approached the repeats with two different viewpoints: they have been considered either as problematic and meaningless echolalia, or as motivated communication meaningful for speakers themselves. This paper examines the functions for which students with special needs use repetition in their interaction with teachers and the ways in which teachers treat these echolalic responses in classroom talk. The research data consists of the video-recordings of lessons in o…
Thermodynamically consistent residual-based gradient plasticity theory and comparison
2006
A gradient plasticity theory for small deformations is presented within the framework of nonlocal continuum thermodynamics. The second principle (Clausius–Duhem inequality), enriched by an additional term named energy residual, is employed in conjunction with the concepts of insulation condition and locality recovery condition, in order to derive all the pertinent restrictions upon the constitutive equations. These include the expressions of the energy residual and of the plastic dissipation density, as well as the PDEs governing the gradient kinematic and isotropic hardening of the material, together with the related higher-order boundary conditions for both the fixed and the moving bounda…
The minor as major: Outsiderness and social class in Saara Turunen’s prose
2021
Saara Turunen’s Sivuhenkilö is a work of autofiction, which tells the story of a year in its unnamed protagonist’s life. Despite her success as an author, the protagonist feels like a minor character in her own life: an outsider both because of her gender and her profession as a writer. In this article, I offer a critical reading of Turunen’s prose by asking what political implications are attached to her handling of outsiderness. I approach outsiderness not merely as a theme, but also as a genre-specific feature peculiar to the tradition of feminist rewriting. Based on my reading of Sivuhenkilö, I argue that regardless of its feminist potential, framing oneself as an outsider can function …
