FEM analysis of push-out test response of Hybrid Steel Trussed Concrete Beams (HSTCBs)
2015
Abstract Aiming to investigate the steel truss–concrete stress transfer mechanism in Hybrid Steel Trussed–Concrete Beams (HSTCBs), a three-dimensional (3D) nonlinear Finite Element (FE) model is developed. The constitutive relationship of the steel composing the plates and the rebars is modeled by means of a quadri-linear law, while the concrete behavior is defined by means of a Concrete Damaged Plasticity (CDP) model, suitable for modeling concrete and brittle materials. Two main failure mechanisms are considered, namely the tensile cracking and the compressive crushing. In order to accurately grasp the complicate dowel and bond phenomena arising at the steel–concrete interface, a 3D solid…

Background questionnaires of PISA : a study of the assessment indicators
2016
El sistema de evaluación de PISA ha generado y continúa generando intensos debates sobre su estructura y utilidad. Este artículo se centra en los cuestionarios de contexto, como forma de analizar y entender de manera adecuada los resultados. Los objetivos son analizar los indicadores de contexto que se utilizan en las distintas ediciones de las pruebas PISA, su utilización en distintos estudios y en los resultados de estos estudios. Se proporciona una visión general del modelo utilizado para conseguir que estos indicadores dejen de ser algo que acompaña a las prueba de rendimiento para que alcancen su verdadero sentido: analizar conjuntamente el rendimiento junto con las variables que…
The Use of Game World Tasks Concepts in Higher Education
2016
The link between tasks presented in games and tasks used in higher education might have more in common than we think. Analysing how tasks work in games and applying those structures to higher education teaching can enable teachers to develop more creative, situated and exciting tasks for their students. In addition, it can improve communication and feedback. Analysis shows that tasks are an area where elements of gamification work. This article looks into the possibility of reproducing the flexibility and key components of game tasks in actual tasks in higher education. We look at the challenges and limitations and ways to solve them. Therefore, we analyse the concept of quest-logs in games…
Individual Decisions and Perceived Form in Collective Free Improvisation
2015
International audience; This paper proposes a first attempt to study quantitatively Collective Free Improvisation (CFI). We report an experiment designed to study the relationship between the improvisers’ individual high-level decisions and the improvisation’s form perceived by external auditors. We recorded 16 trios in which the improvisers used a MIDI-pedal to indicate in real-time a significant change in their own musical production. Expert listeners were later asked to segment each improvisation so that we obtained their perception of the structure. By analysing the correlations between musicians’ individual decisions and listeners’ segmentation points, we discuss how the improvisation’…
Frankfurtian Reflections: A Critical Discussion of Robert Lockie’s “Three Recent Frankfurt Cases”
2016
In a recent article, Robert Lockie brings about a critical examination of three Frankfurtstyle cases designed by David Widerker and Derk Pereboom. His conclusion is that these cases do not refute either the Principle of Alternative Possibilities (PAP) or some cognate leeway principle for moral responsibility. Though I take the conclusion to be true, I contend that Lockie's arguments do not succeed in showing it. I concentrate on Pereboom's Tax Evasion 2 . After presenting Pereboom's example and analyzing its structure, I distinguish two strategies of Lockie's to defend PAP against it, which I call 'No True Alternative Decision' (NTAD) and 'No Responsibility' (NR), respectively. According to…
The Structure of Group Identification
2017
The concept of group identification has been widely discussed in the fields of social psychology and social ontology. The debate has been somewhat unbalanced, however. The structure, nature, and experiential status of groups have been assessed widely and from several perspectives. Instead, the concept of identification as received considerably less attention. This is why the ongoing debate threatens to be misled by various conceptual ambiguities. These ambiguities concern first and foremost the target, structure, and temporal nature of identification. The present article offers a philosophical analysis of the concept and clarifies the conceptual ambiguities haunting the debate. peerReviewed
The influence of task-irrelevant music on language processing: syntactic and semantic structures.
2011
Recent research has suggested that music and language processing share neural resources, leading to new hypotheses about interference in the simultaneous processing of these two structures. The present study investigated the effect of a musical chord's tonal function on syntactic processing (Experiment 1) and semantic processing (Experiment 2) using a cross-modal paradigm and controlling for acoustic differences. Participants read sentences and performed a lexical decision task on the last word, which was, syntactically or semantically, expected or unexpected. The simultaneously presented (task-irrelevant) musical sequences ended on either an expected tonic or a less-expected subdominant ch…
Subjective Perception of Time: Research Applied on Dynamic Psychology
2017
The time marked by the clock hands, the so-called “objective time,” is deeply different from the one perceived by the individual. Starting from this hypothesis, directly connected to the subjective...
Boosting working memory with accelerated clocks
2021
Our perception of time varies with the degree of cognitive engagement in tasks. The perceived passage of time accelerates while working on demanding tasks, whereas time appears to drag during boring situations. Our experiment aimed at investigating whether this relationship is mutual: Can manipulated announcements of elapsed time systematically affect the attentional resources applied to a cognitive task? We measured behavioral performance and the EEG in a whole report working memory paradigm with six items of different colors that each had to be reported after a short delay period. The 32 participants were informed about the current time after each 20 trials, while the clock was running at…
