La transición de Educación Primaria a Educación Secundaria Obligatoria: sentido y significado del uso de recursos y espacios digitales
2019
espanolEl cambio de la Educacion Primaria a la Educacion Secundaria Obligatoria supone el trasvase de informacion y la colaboracion entre centros para realizar acciones conjuntas que faciliten el proceso de transicion y aprovechen el potencial de aprendizaje que ofrece el cambio. Las Tecnologias de la Informacion y la Comunicacion tienen un papel destacado en este proceso de cambio, ya que suponen un medio que facilita la comunicacion e intervencion entre centros, entre familias y entre estudiantes. El proposito fundamental es analizar el grado en que estas son consideradas como beneficiosas en el proceso de gestion del transito de la Primaria a la Secundaria respecto a las tareas de trasva…
The conflicting historical issues and their school approach: a Spanish example
2017
En este estudio se analiza la forma en que los “tiempos difíciles” de la reciente historia española (la Guerra Civil y la dictadura franquista, 1936-1975) han sido tratados tanto en los manuales escolares de historia como en el interior de las aulas, estableciendo, por una parte, los avances historiográficos y didácticos conseguidos y, por otra, las actuales insuficiencias y deficiencias de tales planteamientos desde la perspectiva de un tratamiento realmente democrático y reconciliatorio de los mismos. Los avances han sido muy lentos, tanto en las representaciones sociales del conjunto de la sociedad española como en su presentación escolar. Todo ello permite afirmar que esta cuestión sigu…
Single chords convey distinct emotional qualities to both naïve and expert listeners.
2014
Previous research on music and emotions has been able to pinpoint many structural features conveying emotions. Empirical research on vertical harmony’s emotional qualities, however, has been rare. The main studies in harmony and emotions usually concern the horizontal aspects of harmony, ignoring emotional qualities of chords as such. An empirical experiment was conducted where participants ( N = 269) evaluated pre-chosen chords on a 9-item scale of given emotional dimensions. 14 different chords (major, minor, diminished, augmented triads and dominant, major and minor seventh chords with inversions) were played with two distinct timbres (piano and strings). The results suggest significant…
A Time-Non-Homogeneous Double-Ended Queue with Failures and Repairs and Its Continuous Approximation
2018
We consider a time-non-homogeneous double-ended queue subject to catastrophes and repairs. The catastrophes occur according to a non-homogeneous Poisson process and lead the system into a state of failure. Instantaneously, the system is put under repair, such that repair time is governed by a time-varying intensity function. We analyze the transient and the asymptotic behavior of the queueing system. Moreover, we derive a heavy-traffic approximation that allows approximating the state of the systems by a time-non-homogeneous Wiener process subject to jumps to a spurious state (due to catastrophes) and random returns to the zero state (due to repairs). Special attention is devoted to the cas…
Fractional viscoelastic transversally isotropic Timoshenko beam
2014
In this paper the viscoelastic behavior of pultruded beams has been examined. Pultruded beams are constituted by a polymer infilled with reinforcement in longitudinal direction, while in the orthogonal direction no fiber are present for technological reasons. As a consequence the material has two different behaviors in longitudinal and in orthogonal directions. It follows that pultruded beams are transversally isotropic, and the shear deformation may not be neglected. Based upon the previous observations and assuming for Creep and/or Relaxation test the power law, the constitutive equations are ruled by fractional operators. From constitutive laws, and assuming the Timoshenko beam theory to…
Single-cell analysis of population context advances RNAi screening at multiple levels
2012
Isogenic cells in culture show strong variability, which arises from dynamic adaptations to the microenvironment of individual cells. Here we study the influence of the cell population context, which determines a single cell's microenvironment, in image‐based RNAi screens. We developed a comprehensive computational approach that employs Bayesian and multivariate methods at the single‐cell level. We applied these methods to 45 RNA interference screens of various sizes, including 7 druggable genome and 2 genome‐wide screens, analysing 17 different mammalian virus infections and four related cell physiological processes. Analysing cell‐based screens at this depth reveals widespread RNAi‐induce…
Sounding Together: Family-Centered Music Therapy as Facilitator for Parental Singing During Skin-to-Skin Contact
2017
Introduction: When it comes to the delicate relationship between a baby and its parents, the voices of the parents have a significant role in communicating love, tenderness, and closeness as well as in supporting self-regulation as necessary for secure attachment. Under suboptimal experiences, such as premature birth, infant-directed singing takes on an even more important and therapeutic role since preterm infants miss the finely attuned auditory stimulation of the womb and the mother-infant dyad is disrupted too early.

Path-dependencies, constrained transformations and dynamic agency. An accounting case study informed by both ANT and NIS
2013
Purpose – The purpose of this paper is to discuss the compatibility of actor network theory (ANT) and new institutional sociology (NIS) in analysing a case study of accounting change. Design/methodology/approach – This is an interpretive case study. Findings – The Finnish case city experienced several path-dependent changes concerning performance measurement (PM), financial reporting and the adoption of enterprise resource planning system (ERP). New tools such as the ERP have a potential to transform the actors and to change the agency of the actors. Furthermore, the concepts drawing on both ANT and NIS can together enrich analyses of accounting changes. Research limitations/implications – …
