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…
Reflections towards a generative theory of musical parallelism
2010
Parallelism plays a core role in Lerdahl and Jackendoff's (1983) GTTM, as it rules the emergence of motivic, metrical, grouping and even formal structures. Due to the high amount of detail and complexity characterising associational structures, neither explicit model nor systematic methodology of parallelism-based structural inference has been included into the GTTM. This paper develops a methodological and computational answer to this problem founded on a computational modelling of pattern extraction operations. The paper focuses in particular on the methodological interest of the pattern mining formalism, and in particular its application to the formalisation of grouping and metrical str…
Elaboration of a Critical Paradigm for Interpreting Modern Architecture: The Almost Intangible Essence of Luigi Moretti's Casa del Balilla at Trecate
2021
Modern architecture is not, from a lexical point of view, uniquely definable. The heterogeneity of the twentieth century heritage is therefore a collective wealth that should be protected from the risk of falling into oblivion. In order to avoid this, it could prove fundamental to establish a process of the knowledge of these assets. This should not, however, result in a simple and passive recording of architectural facts: a deep understanding of the complexity of modern architecture, which has as its objective the protection of buildings, could be obtained, for example, through a real and proper decoding of signs, conducted by a critical use of the metalanguage most congenial to the archit…
Employing artificial neural networks to find reaction coordinates and pathways for self-assembly
2021
Capturing the autonomous self-assembly of molecular building blocks in computer simulations is a persistent challenge, requiring to model complex interactions and to access long time scales. Advanced sampling methods allow to bridge these time scales but typically require to construct accurate low-dimensional representations of the transition pathways. In this work, we demonstrate for the self-assembly of two single-stranded DNA fragments into a ring-like structure how autoencoder architectures based on unsupervised neural networks can be employed to reliably expose transition pathways and to provide a suitable low-dimensional representation. The assembly occurs as a two-step process throug…
More Than (Single) Text Comprehension? – On University Students’ Understanding of Multiple Documents
2020
The digital revolution has made a multitude of text documents from highly diverse perspectives on almost any topic easily available. Accordingly, the ability to integrate and evaluate information from different sources, known as multiple document comprehension, has become increasingly important. Because multiple document comprehension requires the integration of content and source information across texts, it is assumed to exceed the demands of single text comprehension due to the inclusion of two additional mental representations: the integrated situation model and the intertext model. To date, there is little empirical evidence on commonalities and differences between single text and mult…
Attraversare
2016
L'articolo propone alcune riflessioni sul concetto di "attraversamento dell'architettura" tramite l'implicazione delle arti visuali e del teatro danza. In particolare, è stata approfondito tale concetto realizzando un "attraversamento" della concatenazione spaziale di Palazzo Riso, Museo d'Arte Contemporanea di Palermo, filtrando lo spazio con la scansione temporale della danza. La performance di teatro danza prende avvio in un precedente momento architettonico, cioè nella Piazza Bologni, che costituisce una delle due estremità del percorso teatrale-spaziale. La piazza costituisce il momento della riflessione, dall'esterno verso l’interno, di una serie di avvenimenti attraverso i quali pren…
Annihilation Operators for Exponential Spaces in Subdivision
2022
We investigate properties of differential and difference operators annihilating certain finite-dimensional subspaces of exponential functions in two variables that are connected to the representation of real-valued trigonometric and hyperbolic functions. Although exponential functions appear in a variety of contexts, the motivation behind this work comes from considering subdivision schemes with the capability of preserving those exponential functions required for an exact description of surfaces parametrized in terms of trigonometric and hyperbolic functions.
Visualization in comparative music research
2007
Computational analysis of large musical corpora provides an approach that overcomes some of the limitations of manual analysis related to small sample sizes and subjectivity. The present paper aims to provide an overview of the computational approach to music research. It discusses the issues of music representation, musical feature extraction, digital music collections, and data mining techniques. Moreover, it provides examples of visualization of large musical collections.
Translators vs translatresses’ strategies: ethical and ideological challenges
2011
In the last few years there has been an increasing interest in the issue of gender in translation practice especially thanks to the work of feminist critics and translators who see the act of translating as an activity which involves making use not of speciously neutral, so-called objective strategies, but rather dynamic procedures and tactics which negotiate and are negotiable, open and contingent, and which never assume feminine subjectivity to be an absolute and stable category. Drawing on such premises, this work will focus on the interrelation between identity, textuality and translation in an attempt to explore the idea that gender representation in translation practice may be shaped …
Preparados para el desastre
2019
La actual crisis política y económica que atraviesa nuestra cotidianeidad supone también una crisis individual que afecta y pone en cuestión tanto las manifestaciones hacia el interior (subjetivas) como también hacia el exterior (de sociabilidad, de inter-subjetividad). Lo mencionado se agrava si tenemos en cuenta el complicado escenario de «colapso» al que nos abocamos según el consenso científico en materia medioambiental, entendido este como una especie de «punto cero» que podría desencadenar una catástrofe de consecuencias inimaginables. Ante este panorama, no son pocas las manifestaciones literarias o cinematográficas que en las últimas décadas se han encargado de asumir este colapso c…
