Els baixonets a Catalunya : una aproximació organològica, funcional i del repertori : el fons musical de Canet de Mar

Aquest treball fa un estudi dels baixonets a Catalunya des de les perspectives organològica, funcional i del repertori. A partir de les informacions aportades pels instruments originals, pels tractats i per estudis especialitats, es defineixen una tipologia instrumental pròpiament hispànica, i unes funcions principalment relacionades amb la música vocal religiosa de mitjans del segle XVI a mitjans del segle XVIII. Posteriorment, es realitza un estudi de la música amb baixonet a la localitat de Canet de Mar. A partir del treball de camp al seu arxiu parroquial, es compilen vuit obres específiques per a baixonet, se'n transcriuen alguns manuscrits, i se'n defineixen els principals aspectes formals i funcionals. El cas de Canet de Mar es pot considerar com un exemple més o menys representatiu de la pràctica instrumental i del repertori específic del baixonet a Catalunya a finals del segle XVII i començaments del segle XVIII.

Testing I(1) against I(d) alternatives in the presence of deteministic components

This paper discusses the role of deterministic components in the DGP and in the auxiliaryregression model which underlies the implementation of the Fractional Dickey-Fuller (FDF) test for I(1) against I(d) processes with d [0, 1). This is an important test in many economic applications because I(d) processess with d < 1 are mean-reverting although, when 0.5 = d < 1, like I(1) processes, they are nonstationary. We show how simple is the implementation of the FDF in these situations, and argue that it has better properties than LM tests. A simple testing strategy entailing only asymptotically normally distributedtests is also proposed. Finally, an empirical application is provided where the FDF test allowing for deterministic components is used to test for long-memory in the per capita GDP of several OECD countries, an issue that has important consequences to discriminate between growth theories, and on which there is some controversy.

Learning of courtship components in Drosophila mercatorum (Paterson & Wheller) (Diptera, Drosophilidae)

In Drosophila, courtship is an elaborate sequence of behavioural patterns that enables the flies to identify conspecific mates from those of closely related species. This is important because drosophilids usually gather in feeding sites, where males of various species court females vigorously. We investigated the effects of previous experience on D. mercatorum courtship, by testing if virgin males learn to improve their courtship by observing other flies (social learning), or by adjusting their pre-existent behaviour based on previous experiences (facilitation). Behaviours recorded in a controlled environment were courtship latency, courtship (orientation, tapping and wing vibration), mating and other behaviours not related to sexual activities. This study demonstrated that males of D. mercatorum were capable of improving their mating ability based on prior experiences, but they had no social learning on the development of courtship.

Are Americans' musical preferences more omnivores today?

Although we found a general trend favouring the omnivorousness thesis, as soon as we adjusted it to a set of structural factors and consumers tastes it was clear that this was caused by elitist inclusive omnivores who had increased the scope of their tastes. In general, younger cohorts were becoming less omnivorous, nevertheless, they were also becoming more educated and had greater to higher levels of inc ome, making the youth moreomnivorous. As expected, upscale consumers set limits on their popular taste: musicalgenres, whose audiences had educational levels below the mean profile were less preferredby upscale respondents. In spite of this, as time passed, some popular brows gained socialstatus.

L’alè del clarinet : la respiració en la interpretació musical amb el clarinet

El projecte és una proposta d’exploració i reflexió personal sobre la respiració en la interpretació musical amb el clarinet i els aspectes corporals i pedagògics relacionats que fan possible l’estat psicofísic necessari per a una interpretació fluïda, creativa i amb veu pròpia. Per al seu desenvolupament, s’ha aprofundit en el coneixement de l’anatomia i fisiologia de la respiració, així com en la consciència corporal per aplicar-ho a la interpretació amb el clarinet i desenvolupar unes eines per a la seva didàctica. El mètode de treball consta de tres fases: la documentació, les entrevistes i les sessions didàctiques. Tot plegat ha significat un profund aprenentatge a nivell personal.

Comparison of the polynomial model against explicit measurements of noise components for different mammography systems.

Given the adverse impact of image noise on the perception of important clinical details in digital mammography, routine quality control measurements should include an evaluation of noise. The European Guidelines, for example, employ a second-order polynomial fit of pixel variance as a function of detector air kerma (DAK) to decompose noise into quantum, electronic and fixed pattern (FP) components and assess the DAK range where quantum noise dominates. This work examines the robustness of the polynomial method against an explicit noise decomposition method. The two methods were applied to variance and noise power spectrum (NPS) data from six digital mammography units. Twenty homogeneously exposed images were acquired with PMMA blocks for target DAKs ranging from 6.25 to 1600 µGy. Both methods were explored for the effects of data weighting and squared fit coefficients during the curve fitting, the influence of the additional filter material (2 mm Al versus 40 mm PMMA) and noise de-trending. Finally, spatial stationarity of noise was assessed.Data weighting improved noise model fitting over large DAK ranges, especially at low detector exposures. The polynomial and explicit decompositions generally agreed for quantum and electronic noise but FP noise fraction was consistently underestimated by the polynomial method. Noise decomposition as a function of position in the image showed limited noise stationarity, especially for FP noise; thus the position of the region of interest (ROI) used for noise decomposition may influence fractional noise composition. The ROI area and position used in the Guidelines offer an acceptable estimation of noise components. While there are limitations to the polynomial model, when used with care and with appropriate data weighting, the method offers a simple and robust means of examining the detector noise components as a function of detector exposure.

NOTCH1 can initiate NF-κB activation via cytosolic interactions with components of the T cell Signalosome.

T cell stimulation requires the input and integration of external signals. Signaling through the T cell receptor (TCR) is known to induce formation of the membrane-tethered CBM complex, comprising CARMA1, BCL10, and MALT1, which is required for TCR-mediated NF-κB activation. TCR signaling has been shown to activate NOTCH proteins, transmembrane receptors also implicated in NF-κB activation. However, the link between TCR-mediated NOTCH signaling and early events leading to induction of NF-κB activity remains unclear. In this report, we demonstrate a novel cytosolic function for NOTCH1 and show that it is essential to CBM complex formation. Using a model of skin allograft rejection, we show in vivo that NOTCH1 acts in the same functional pathway as PKCθ, a T cell-specific kinase important for CBM assembly and classical NF-κB activation. We further demonstrate in vitro NOTCH1 associates physically with PKCθ and CARMA1 in the cytosol. Unexpectedly, when NOTCH1 expression was abrogated using RNAi approaches, interactions between CARMA1, BCL10, and MALT1 were lost. This failure in CBM assembly reduced inhibitor of kappa B alpha phosphorylation and diminished NF-κB-DNA binding. Finally, using a luciferase gene reporter assay, we show the intracellular domain of NOTCH1 can initiate robust NF-κB activity in stimulated T cells, even when NOTCH1 is excluded from the nucleus through modifications that restrict it to the cytoplasm or hold it tethered to the membrane. Collectively, these observations provide evidence that NOTCH1 may facilitate early events during T cell activation by nucleating the CBM complex and initiating NF-κB signaling.

Entornos e-learning como soporte de aprendizaje a la asignatura educación musical en infancia

La música es una asignatura obligatoria dentro de la etapa educativa de primaria. Hemos detectado varios profesores de distintas áreas educativas, entre ellas el área de música, que utilizan plataformas de e-learning y herramientas web como apoyo para enseñar el currículum que marca el “Departament d‟Educació de la Generalitat de Catalunya”. A partir del cuerpo de análisis se ha dibujado el panorama en plataformas de e-learning, analizando las tipologías y usos. A través de la muestra de plataformas de e-learning en educación musical se han detectado cuatro escuelas con plataformas de e-learning en fase avanzada. Se realiza un estudio de caso sobre una de estas plataformas para hacer el análisis de contenidos y validar el formato de entrevista utilizado, esto nos ha servido para crear un modelo que pueda ser utilizado en otros centros con plataforma de e-learning para la asignatura específica de música.
