La voce e la risonanza. Dal grido in una caverna alla performance di Stimmung
Che rapporto lega l’immagine della materialità del suono prodotta dal corpo sonoro in risonanza ad una possibile lettura fenomenologica dell’eco come oggettivazione della voce? L’autore cerca di dar ragione del concetto di voce in eco, come oggettivazione dell’evento sonoro attraverso una analisi puntuale di Stimmung di Karlheinz Stockhausen. La scelta del brano è motivata dall 'interesse che questo brano dimostra nei confronti di una tecnica musicale, il canto armonico, che mette in gioco in maniera coerente l'intuizione del corpo come cavità e le sue proprietà risonantiche. In questa prospettiva acquistano particolare rilievo le interferenze che coniugano le componenti performative al disegno che deve sostenere il costituirsi di regole nell’elaborazione formale del brano: tale intreccio porta alla luce il livello impersonale ed intersoggettivo della dimensione dell’ascolto musicale
Percezione aptica, feedback sonoro e mediazione tecnologica
Starting from the analysis of a case study, this article presents the creation of a technological and pedagogical device enabling real time interaction between gesture and sound. The research has been developed during the class of “Movement Analysis” at Nice University. Several students from the Bachelor’s degree programme in Dance have been involved. This study analyzes how the sonification of both movement and muscular activity allows students to transduce haptic informations, previously experienced during the manipulation of an object, into somatic qualities, thereby enabling the construction of dancing patterns
L'eco sonora del gesto. Appunti per una ricerca sperimentale sul concetto di corpo sonoro nelle performance interattive
Com'è sotto gli occhi di tutti, l'avvento delle tecnologie digitali in ambito artistico ha radicalmente modificato non solo il modo in cui le pratiche performative si sono approcciate alla creazione di nuovi linguaggi espressivi ma anche e sopratutto il nostro modo di fruire l'opera d'arte secondo paradigmi percettivi tecnologicamente orientati. Ad oggi, uno degli aspetti più interessanti dell'ibridazione tra ricerca artistica e tecnologica riguarda l'impiego sempre più esteso di sistemi responsivi in grado di captare ed interpretare il comportamento del performer e tradurlo in un contenuto virtuale visivo o sonoro. Il corpo, inerendo alla griglia sensoriale imposta dallo strumento fa di questo un'estensione, una protesi, un'eco sonora, dell'apparato senso-motorio (ma anche neurale). La tesi centrale di questo testo è che a partire da un tale fenomeno sia possibile una significativa quanto originale rielaborazione del concetto di corpo sonoro
From haptic perception to movement: a phenomenological study on sound and technological mediation in dance pedagogy
Abstract:It is well known that, interactive media have become a major issue in both academic research and artistic practice. During the last years, motion sensing technologies have been proven to be a useful mean for movement’s analysis in relation to dance and music performances. Different domaines ranging from artistic creative process to pedagogical applications have been involved. Within this context, many scholars pointed out the crucial importance of sound agency in developing sensorimotor awareness. A phenomenological approach seem to be taking an increasingly prominent position in informing such theoretical framework. Multimodality and embodiment have been revealed to be the main features in order to understand the relation between movement, sound and mediation technologies. The case study presented is part of a research project that involves dance pedagogy and new technologies at Nice University. This paper focus on description of an interactive experience based on motion sensing/bio-signals technologies allowing dance students to explore the sense of touch in connection to objets’ manipulation and sound production. The goal of the experience was to analyze how multimodal connection between haptic and auditive feedbacks can be incorporated trough gesture and how, this relation affects perceptual organization of movement. As it emerges from this study, sound feedbacks seem to facilitate the transition from manipulation gestures to dance movements. Moreover, the arise of a “sonorous presence” enhances both proprioceptive awareness and corporeal imagination thereby affecting the movement composition process.Keywords: Interactive Technologies.

DA PERCEPÇÃO HAPTICA AO MOVIMENTO: UM ESTUDO FENOMENOLÓGICO SOBRE A MEDIAÇÃO SONORA E TECNOLÓGICA NA PEDAGOGIA DA DANÇAResumo:Como é sabido, a mídia interativa tornou-se um problema importante tanto na pesquisa acadêmica quanto na prática artística. Nos últimos anos, as tecnologias de detecção de movimento provaram ser um meio útil para a análise do movimento em relação à dança e as performances musicais. São envolvidos diferentes domínios que vão do processo criativo artístico às aplicações pedagógicas. Nesse contexto, muitos estudiosos apontaram a importância crucial da agência de som no desenvolvimento de conscientização sensório-motora. A abordagem fenomenológica parece assumir uma posição cada vez mais proeminente na informação desse quadro teórico. A multimodalidade e a corporificação1 são reveladas como as principais características para entender a relação entre movimento, som e mediação tecnológica. O estudo de caso apresentado faz parte de um projeto de pesquisa envolvendo pedagogia da dança e novas tecnologias na Universidade de Nice. Este artigo concentra-se na descrição de uma experiência interativa baseada em detecção de movimento e tecnologias bio-eletrônicas que permitem aos estudantes de dança explorar o senso de toque em conexão com a manipulação de objetos e a produção de som. O objetivo da experiência foi analisar como a conexão multimodal entre feedbacks hápticos e auditivos pode ser incorporados por meio de gesto e como essa relação afeta a organização perceptiva do movimento. Como resulta deste estudo, os áudio feedbacks parecem facilitar a transição de gestos de manipulação para movimentos de dança. Além disso, o surgimento de uma “presença sonora” aumenta a consciência proprioceptiva e a imaginação corporal, afetando assim o processo de composição do movimento.Palavras-chave: Tecnologia Interativa.

Hemodynamic sensor in cardiac implantable electric devices: the endocardial accelaration technology
There have been substantial progresses in the technology of cardiac implantable electric devices (CIEDs) during the past decades. One of the progresses is represented by the development of a hemodynamic sensor embedded at the tip of a pacing lead that measures myocardial contractility by the analysis of myocardial mechanical vibrations occurring during the cardiac cycle. This sensor, providing continuous hemodynamic monitoring, could play an important role in clinical practice because of several clinical applications in CIEDs recipients. The objectives of this work are to report how this sensor operates and to review the main findings about its clinical applications
Archiveros ¡Manos a la obra! La extensión universitaria en archivología: experiencia en la recuperación del patrimonio cultural del diario La Idea
Luego del trajín del rescate de los ejemplares históricos del diario La Idea, la Asociación de Amigos de La Idea se pone en contacto con la Secretaría de Extensión de la Facultad de Filosofía y Humanidades, ya que surgen diversas necesidades para conseguir que estos diarios antiguos puedan ser consultados como objetos culturales. La particularidad de este grupo de periódicos es, desde el punto de vista archivístico, que debido a su procedencia se constituyen en un fondo archivístico, que aunque incompleto, refleja casi un siglo de actividad periodística del Noroeste Cordobés.Para que estos impresos puedan ser utilizados por quienes quieran, sin ningún condicionamiento, debemos aplicar técnicas interventivas de conservación documental para recuperar su materialidad que ha sufrido graves deterioros y contaminación. Asimismo, debemos aplicar tratamientos archivísticos sobre la información, para construir uninstrumento de recuperación eficiente con la finalidad de evitar la excesiva manipulación de los diarios antiguos.Se describen las tareas y actividades que confluyeron en la propuesta Salvaguarda del periódico La Idea, patrimonio cultural de la ciudad de Cruz del Eje que fue aprobado como proyecto de extensión de la Facultad de Filosofía y Humanidades a finales del año 2017
Oxygen supersaturation protects coastal marine fauna from ocean warming
Ocean warming affects the life history and fitness of marine organisms by, among others, increasing animal metabolism and reducing oxygen availability. In coastal habitats, animals live in close association with photosynthetic organisms whose oxygen supply supports metabolic demands and may compensate for acute warming. Using a unique high-frequency monitoring dataset, we show that oxygen supersaturation resulting from photosynthesis closely parallels sea temperature rise during diel cycles in Red Sea coastal habitats. We experimentally demonstrate that oxygen supersaturation extends the survival to more extreme temperatures of six species from four phyla. We clarify the mechanistic basis of the extended thermal tolerance by showing that hyperoxia fulfills the increased metabolic demand at high temperatures. By modeling 1 year of water temperatures and oxygen concentrations, we predict that oxygen supersaturation from photosynthetic activity invariably fuels peak animal metabolic demand, representing an underestimated factor of resistance and resilience to ocean warming in ectotherms
Practicing a Musical Instrument in Childhood is Associated with Enhanced Verbal Ability and Nonverbal Reasoning
Background: In this study we investigated the association between instrumental music training in childhood and outcomes closely related to music training as well as those more distantly related. Methodology/Principal Findings: Children who received at least three years (M = 4.6 years) of instrumental music training outperformed their control counterparts on two outcomes closely related to music (auditory discrimination abilities and fine motor skills) and on two outcomes distantly related to music (vocabulary and nonverbal reasoning skills). Duration of training also predicted these outcomes. Contrary to previous research, instrumental music training was not associated with heightened spatial skills, phonemic awareness, or mathematical abilities. Conclusions/Significance: While these results are correlational only, the strong predictive effect of training duration suggests that instrumental music training may enhance auditory discrimination, fine motor skills, vocabulary, and nonverba

La pensée sonore du corps : Pour une approche écologique à la médiation technologique, au mouvement et à l'interaction sonore
During the last years, motion sensing technologies have radically transformed the universe of the artistic practice. This dramatic change has recently inspired new perspectives in scientific research. Music is actually among the most affected domaines by this expressive and epistemological renewal. The interactive relation between mediation technology, movement and sound, seems to be declined into two main modalities : on one hand, movement analysis’ technologies allow to study mutual connections between acoustic phenomenon and sensorimotor system, on the other hand, embodied understanding of musical experience can help to devise an holistic approach to interactive systems conception and development. Given this background scenario, this thesis focuses on how movement’s qualities transformation into sound allows the performer to become aware of physiological and imaginative processes in gesture composition. In this framework, sound feedback-movement relation is analyzed from an ecological point of view. According to this approach, mediation technology seems to elicit an autopoietic process of extension and intensification of corporeality. Especially in the artistic performance, sound interaction offers to performer a new sensorial geography that allows him/her to renew his/her perceptive organization and thereby rethink expressive composition of movement.Au cours des dernières années, l’avènement des technologies de captation du mouvement a radicalement transformé l’univers de la pratique artistique tout en ouvrant des perspectives inédites pour la recherche scientifique. La musique est actuellement l’un des domaines les plus impliqués dans ce renouvellement expressif et épistémologique. Dans ce cadre, les processus d’interaction entre médiation technologique, mouvement et son, semblent se décliner selon deux modalités majeures : d’une part, les technologies d’analyse du mouvement permettent d’étudier expérimentalement la connexion mutuelle entre phénomène acoustique et système sensori-moteur; de l’autre, la compréhension de la nature incarnée de l’expérience musicale oriente la conception et le développement de technologies interactives pour la performance vers un modèle plus holistique. En partant de ces prémisses, cette thèse porte sur la manière dont la transformation des aspects imperceptibles du mouvement en données perceptibles – sous forme de son – permet de prendre conscience des processus physiologiques et figuratifs qui sont à la base du geste. Dans ce contexte, la relation entre mouvement et feedback sonore est analysée selon une perspective écologique visant à mettre en lumière comment la médiation technologique induit un processus d’extension et d’intensification autopoïétique de l’anatomie corporelle. Notamment dans le cas de la pratique performative, l’interaction sonore offre alors au performeur la possibilité de redéfinir sa propre organisation perceptive sur la base d’un un nouveau répertoire des données sensorielles, lui permettant ainsi de repenser la composition expressive du mouvement
