La enseñanza del verbo y la actividad metalingüística de los alumnos. Dos investigaciones en aulas de Secundaria
2021
La investigación en Didáctica de la lengua persigue entender las relaciones entre la perspectiva de la enseñanza, la perspectiva del aprendizaje y la de los contenidos trabajados en el aula de Lengua. Este artículo pone el foco en el verbo como contenido gramatical a partir de dos investigaciones centradas en la actividad metalingüística de los alumnos de Educación Secundaria Obligatoria. En la primera, los estudiantes intentan explicar las diferencias entre los tiempos verbales del pasado como paso previo para utilizarlos en la escritura. En la segunda, la reflexión se centra en el subjuntivo a partir de una actividad de pares mínimos que tiene como objetivo comprender cómo conceptualizan …
Discovery of hard phase lags in the pulsed emission of GRO J1744-28
2016
We report on the discovery and energy dependence of hard phase lags in the 2.14 Hz pulsed profiles of GRO J1744-28. We used data from XMM-Newton and NuSTAR. We were able to well constrain the lag spectrum with respect to the softest (0.3--2.3 keV) band: the delay shows increasing lag values reaching a maximum delay of $\sim$ 12 ms, between 6 and 6.4 keV. After this maximum, the value of the hard lag drops to 7 ms, followed by a recovery to a plateau at 9 ms for energies above 8 keV. NuSTAR data confirm this trend up to 30 keV, but the measurements are statistically poorer, and therefore, less constraining. The lag-energy pattern up to the discontinuity is well described by a logarithmic fun…
A SURVEY ON THE ACOUSTICAL CONDITIONS IN A SPANISH SECONDARY SCHOOL
1992
The present paper reports on a study of the acoustical conditions in a secondary school of Gandia (Spain). Our data include a complete information on noise levels, reverberation times and speech intelligibility of classrooms, together with the results of two social surveys adressed to teachers and students in order to know their attitudes towards this problem.
Nonnegative signal factorization with learnt instrument models for sound source separation in close-microphone recordings
2013
Close-microphone techniques are extensively employed in many live music recordings, allowing for interference rejection and reducing the amount of reverberation in the resulting instrument tracks. However, despite the use of directional microphones, the recorded tracks are not completely free from source interference, a problem which is commonly known as microphone leakage. While source separation methods are potentially a solution to this problem, few approaches take into account the huge amount of prior information available in this scenario. In fact, besides the special properties of close-microphone tracks, the knowledge on the number and type of instruments making up the mixture can al…
On the Robustness of Deep Features for Audio Event Classification in Adverse Environments
2018
Deep features, responses to complex input patterns learned within deep neural networks, have recently shown great performance in image recognition tasks, motivating their use for audio analysis tasks as well. These features provide multiple levels of abstraction which permit to select a sufficiently generalized layer to identify classes not seen during training. The generalization capability of such features is very useful due to the lack of complete labeled audio datasets. However, as opposed to classical hand-crafted features such as Mel-frequency cepstral coefficients (MFCCs), the performance impact of having an acoustically adverse environment has not been evaluated in detail. In this p…
Frequency-Sliding Generalized Cross-Correlation: A Sub-Band Time Delay Estimation Approach
2020
The generalized cross correlation (GCC) is regarded as the most popular approach for estimating the time difference of arrival (TDOA) between the signals received at two sensors. Time delay estimates are obtained by maximizing the GCC output, where the direct-path delay is usually observed as a prominent peak. Moreover, GCCs play also an important role in steered response power (SRP) localization algorithms, where the SRP functional can be written as an accumulation of the GCCs computed from multiple sensor pairs. Unfortunately, the accuracy of TDOA estimates is affected by multiple factors, including noise, reverberation and signal bandwidth. In this paper, a sub-band approach for time del…
Ricostruire la diacronia della sintassi ladino-dolomitica con l'aiuto di Joppi. Il caso dei costrutti percettivi
2016
L'articolo discute la duplice variazione che riguarda i costrutti percettivi delle varietà ladine: da un lato l'uso di due forme verbali diverse (gerundi e infiniti preposizionali), e dall'altro le differenze tra questi costrutti in ladino e nelle varietà iberoromanze. Sulla base dei dati tratti principalmente dalla raccolta di testi friuliani di Vincenzo Joppi (1878), si mostrerà come le peculiarità dei costrutti percettivi ladini siano dovute al loro carattere conservativo, ma anche a un'innovazione interna al ladino. This article suggests that a diachronic analysis of a specific syntactic phenomenon in Romance allows us to formulate hypotheses that can be extended to those varieties that…
La formazione dei formatori e la Danzamovimento terapia
2008
La monografia, centrata sulla formazione di futuri formatori (studenti di Scienze della Formazione) e di formatori in servizio (insegnanti), pone l’accento, individuando punti di contatto e possibili collegamenti, sui temi seguenti: - l’interconnessione mente-corpo con riferimenti non solo agli ambiti filosofico e pedagogico, ma anche alle ultime acquisizioni delle neuroscienze - la valenza dei linguaggi artistico espressivi nello sviluppo della personalità creativa e nella formazione dei formatori - la specificità della danzamovimeto-terapia e la sua funzione nell’integrazione del sé e delle competenze espressivo-comunicative, osservative, relazionali Nel testo vengono poi riportate due es…
The role of caregiver in inclusion processes of separated children: linguistic and psycho-pedagogical reflections.
2016
Great attention has been paid to human rights protection of separated children. One example is given by the several editions of Statement of Good Practice (SCEP) that provide a straightforward account of the policies and practices required to implement and protect the human rights of separated children. Nevertheless, when coming into terms with the various needs of separated children, various difficulties are experienced linked to the unawareness of the implications linguistic and cultural diversity may have. In building a framework for action and advocacy not only one has to be linguistically skilled but also aware of how a particular society works and that language implies culture, societ…
