Mollusks: how are they arranged in the rocky intertidal zone?

Mollusks occupy different kinds of environments, including the intertidal zone. The present study investigated the spatial distribution of mollusks on beach rocks of the intertidal zone of Pacheco Beach in the state of Ceará, Brazil. Sampling occurred from August 2006 to September 2007. Across two transects, six samples of 0.25 m² were collected monthly in gaps of 30 m (0 m, 30 m, 60 m, 90 m, 120 m and 150 m). The mollusks were counted in field, and samples of sediment and algae were taken for further analysis. A total of 74,515 individuals were found and classified into 67 species, 52 genera and 39 families. Gastropods were predominant, corresponding to 73.1% of the species, followed by bivalves (22.4%) and chitons (4.5%). Caecum ryssotitum de Folin, 1867 was the most abundant taxon, representing 68.8% of total specimen findings. In general, species were mostly found in Middle Littoral zone (samples 60 m and 90 m), suggesting that the greater number of microenvironments available in this area may contribute to establishment and survival.

Towards an emotion-driven interactive music system: ridging the gaps between affect, physiology and sound generation

Report for the scientific sojourn at the Stanford University from January until June 2007. Music is well known for affecting human emotional states, yet the relationship between specific musical parameters and emotional responses is still not clear. With the advent of new human-computer interaction (HCI) technologies, it is now possible to derive emotion-related information from physiological data and use it as an input to interactive music systems. Providing such implicit musical HCI will be highly relevant for a number of applications including music therapy, diagnosis, nteractive gaming, and physiologically-based musical instruments. A key question in such physiology-based compositions is how sound synthesis parameters can be mapped to emotional states of valence and arousal. We used both verbal and heart rate responses to evaluate the affective power of five musical parameters. Our results show that a significant correlation exists between heart rate and the subjective evaluation of well-defined musical parameters. Brightness and loudness showed to be arousing parameters on subjective scale while harmonicity and even partial attenuation factor resulted in heart rate changes typically associated to valence. This demonstrates that a rational approach to designing emotion-driven music systems for our public installations and music therapy applications is possible.

Tocant totes les tecles: Vicenç Sabater, un obrer de la música

Treball de recerca realitzat per un alumne d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit cientí­fic del Jovent l'any 2009. El treball tracta sobre la petita memòria històrica en la faceta de l'oci de la nostra societat , el ball i la música concretament, centrat en la memòria de l'avi de l'autor, músic, arranjador i compositor. Es tracta doncs, d'una investigació sobre la música de ball a Barcelona i a Catalunya, i en general també a Europa, atès que gràcies a les vivències d'en Vicenç Sabater (l'avi), es relata com era la seva feina i el seu ofici, el de músic. La recerca està ordenada cronològicament, començant pel seu naixement (1930), la formació i les primeres actuacions, passant per tota la seva vida personal, però sobretot professional, i conclou amb un epíleg sense el qual el treball de recerca no tindria sentit, ja que aquest explica com el Vicenç no s'ha jubilat mai, perquè sempre ha estat treballant amb la música, i perquè sempre que el seu físic li permeti, ell s'hi seguirà dedicant. El treball inclou un apartat destacat de la llarga etapa (30 anys) de Sabater amb el grup musical 'Rudy Ventura y su conjunto'. Molta d'aquesta informació s'obté a través d'entrevistes a dos dels cinc integrants del grup: el mateix Jaume Ventura, i en Joan Antoni Calvet, cantant i bateria, respectivament. Apartat que, dissortadament, s'ha convertit en el meu involuntari i modest homenatge a Jaume ('Rudy') Ventura , recentment traspassat.

Sacred Music, Sacred Journeys : What Makes an Event Postcolonial?

Fanon, Senghor, and Ela took a radical stance in criticising the structures and mechanisms of power in hegemonic situations and relations between colonial subjects and colonial masters. They aimed to liberate African societies by decolonising the mind, culture and religion of colonial subjects. In this respect, we are concerned with the continuities and ruptures of the colonial encounter and its unequal relationships. Switzerland does not have an official colonial history and yet, Swiss companies and migrants were and are part of the world's colonies. In our contribution, we question what makes an event postcolonial : in other words, how are postcolonial relations negotiated in Switzerland? We discuss this question by analysing two annual sacred journeys in Switzerland that have been invented for and by African Christians (clerics and laity) together with the leaders of the Swiss Catholic church : one to the relics of African saints in St. Maurice, canton Valais and the other to the Black Madonna, the Virgin Mary of Einsiedeln, in the canton Schwyz. These events are empowered by the performance of African choirs - their music, dance, and costumes - but to which end and in which way?

Hyperventilation in anticipatory music performance anxiety

Objectives and Methods: Self-report studies have shown an association between music performance anxiety (MPA) and hyperventilation complaints. However, hyperventilation was never assessed physiologically in MPA. This study investigated the self-reported affective experience, self-reported physiological symptoms, and cardiorespiratory variables including partial pressure of end-tidal CO(2) (Petco(2)), which is an indicator for hyperventilation, in 67 music students before a private and a public performance. The response coherence between these response domains was also investigated.ResultsFrom the private to the public session, the intensity of all self-report variables increased (all p values < .001). As predicted, the higher the musician's usual MPA level, the larger were these increases (p values < .10). With the exception of Petco(2), the main cardiorespiratory variables also increased from the private to the public session (p values < .05). These increases were not modulated by the usual MPA level (p values > .10). Petco(2) showed a unique response pattern reflected by an MPA-by-session interaction (p < .01): it increased from the private to the public session for musicians with low MPA levels and decreased for musicians with high MPA levels. Self-reported physiological symptoms were related to the self-reported affective experience (p values < .05) rather than to physiological measures (p values > .17).ConclusionsThese findings show for the first time how respiration is stimulated before a public performance in music students with different MPA levels. The hypothesis of a hyperventilation tendency in high-performance-anxious musicians is supported. The response coherence between physiological symptoms and physiological activation is weak.

Concepció, disseny i implantació d'un sistema de proves psicomètriques de rendiment acadèmic per a la matèria d'Història de la Música

Amb aquest projecte s'ha treballat en la direcció de: 1) Implementar un nou recurs en un projecte global de millora de la qualitat docent i d’aplicació de les TIC a l’ensenyament de les diferents assignatures de la matèria d’Història de la Música a la UdL en curs des de fa alguns anys. Concretament, diverses eines per a l’autoavaluació de l’alumnat a través d’un banc de preguntes segons el format de les proves psicomètriques (proves objectives en l’avaluació del rendiment acadèmic dels estudiants o d’elecció múltiple). 2) Arribar a disposar d’un extens banc de preguntes d’elecció múltiple i correcció objectiva en diferents formats, ordenades per blocs, temes, nivells de dificultat, etc., que reuneixin els criteris mínims de fiabilitat, objectivitat i validesa necessaris per a una correcta avaluació del rendiment acadèmic. Entenem que l’avaluació ha de tenir utilitats diferents que van més enllà de la simple puntuació de l’alumnat. Ha de servir també per millorar la docència, per facilitar l’aprenentatge de l’alumne, per assegurar un nivell de competència mínim, per discriminar entre estudiants o per informar la pròpia institució. 3) Aconseguir que l’alumne, a través de l’autoavaluació, entengui que aquest tipus de proves són instruments per continuar aprenent. En aquest sentit les proves d’elecció múltiple permeten tot un seguit d’opcions que ho afavoreixen. 4) Elaborar una eina amb capacitat de generar estadístiques, índex de discriminació i de fer l’anàlisi d’items, tot permetent anar redefinint i millorant els ítems.

Music identification

L'evolució ens els últims decennis de les possibilitats relacionades amb les tecnologies de la informació han provocat l'aparició de diferents camps, entre ells l'anomenat “recuperació de música basant-se en el contingut”, que tracta de calcular la similitud entre diferents sons. En aquest projecte hem fet una recerca sobre els diferents mètodes que existeixen avui en dia, i posteriorment n'hem comparat tres, un basat en característiques del so, un basat en la transformada discreta del cosinus, i un que combina els dos anteriors. Els resultats han mostrat, que el basat en la transformada de Fourier és el més fiable.

On the writer identification in old handwritten music scores

Report for the scientific sojourn at the University of Bern, Swiss, from Mars until June 2008. Writer identification consists in determining the writer of a piece of handwriting from a set of writers. Even though an important amount of compositions contains handwritten text in the music scores, the aim of the work is to use only music notation to determine the author. It’s been developed two approaches for writer identification in old handwritten music scores. The methods proposed extract features from every music line, and also features from a texture image of music symbols. First of all, the music sheet is first preprocessed for obtaining a binarized music score without the staff lines. The classification is performed using a k-NN classifier based on Euclidean distance. The proposed method has been tested on a database of old music scores from the 17th to 19th centuries, achieving encouraging identification rates.
