Cuerpos moldeables y vidas modulables: La invención del estado holísticamente saludable como bienestar (integral)

2020

The article argues ?from the Deleuzian concepts of society of control, moulding and modulation and the Rosean theory on the economization and medicalization of life? that the expansion of the concept of health in terms of integral and subjective well-being is the effect of a socio-historical shift in the way we relate to this signifier, and therefore to our bodies and ourselves. We use this interpretative network to analyze the effects that the biopsychosocial health paradigm has had in the context of aesthetic surgery and fitness practice. As a result, we see that the expansion of the concept of health has extended the domain of medicine into the spheres of personal care and physical appea…

The redefinition of gender roles in immigrant women: the importance of local spaces in global processes

2017

ABSTRACTIn today’s complex, intercultural, transnational, glocalized world, linking conceptual analyses and theoretical representations to the empirical study of female migration also requires, among other aspects, acknowledging the importance of the arrival context in the redefinition of gender roles, since it operates as an area of opportunity or containment mainly due to a number of specific features, which interacts with women’s economic, cultural and social capital, to produce different results in the situation of migrant women. The context of arrival and the subjects, conceived of as actors inserted in social structures where they have scope for action, is the focus of our analysis. T…

Study of 3D sound for an audio-visual interaction in enriched virtual environment

2011

Most of the applications integrating 3D sound in virtual environment are limited to acoustic simulation. The objective of this thesis is to study the added value of 3D sound in the interaction with virtual environment. We developed an audio stimulation technique called "Artificial Spatial Audio Sensation: (ASAS)" based on the creation of audio effects. This technique conveys the sensations of spatialized sound that allows accurate sound source localization in azimuth and in elevation. In order to improve the localization time we also developed a model that integrates Head-Related Transfer Function (HRTF) with the ASAS technique. For the simulation of the depth of spatial sound sources, we d…

Innovative Tools for Sound Sketching Combining Vocalizations and Gestures

2016

International audience; Designers are used to produce a variety of physical and digital representations at different stages of the design process. These intermediary objects (IOs) do support the externalization of ideas and the mediation with the different stakeholders. In the same manner, sound designers deliver several intermediate sounds to their clients, through iteration and refinement. In fact, these preliminary sounds are sound sketches representing the intermediate steps of an evolving creation. In this paper we reflect on the method of sketching sounds through vocalizations and gestures, and how a technological support, grounded in the understanding of the design practice, can fost…

Advantages of binaural hearing provided through bimodal stimulation via a cochlear implant and a conventional hearing aid: a 6-month comparative stud…

2005

Our study data demonstrate the additional benefit derived from continued use of a contralateral hearing aid (HA) post-cochlear implantation for speech recognition ability in quiet and in noise. Postoperative bimodal stimulation is recommended for all subjects who show some speech recognition ability in the contralateral ear as it may offer binaural listening advantages in various listening situations encountered in everyday life.To assess the benefits derived from bimodal stimulation for experienced HA users implanted with a cochlear implant (CI) (score=20% in disyllabic test). The correlation between pre- and postoperative performance on speech perception measures was examined to determine…

Source localization of event-related potentials to pitch change mapped onto age-appropriate MRIs at 6 months-of-age

2010

Auditory event-related potentials (ERPs) have been used to understand how the brain processes auditory input, and to track developmental change in sensory systems. Localizing ERP generators can provide invaluable insights into how and where auditory information is processed. However, age-appropriate infant brain templates have not been available to aid such developmental mapping. In this study, auditory change detection responses of brain ERPs were examined in 6-month-old infants using discrete and distributed source localization methods mapped onto age-appropriate magnetic resonance images. Infants received a passive oddball paradigm using fast-rate non-linguistic auditory stimuli (tone do…

Cumulative-Sum-Based Localization of Sound Events in Low-Cost Wireless Acoustic Sensor Networks

2014

Wireless acoustic sensor networks (WASNs) are known for their potential applications in multiple areas, such as audio-based surveillance, binaural hearing aids or advanced acoustic monitoring. The knowledge of the spatial position of a source of interest is usually a requirement for many of these applications. Therefore, source localization is an important problem to be addressed in WASNs. Unfortunately, most localization algorithms need costly signal processing stages that prevent them from being implemented in low-cost sensor networks, requiring additional modules for signal acquisition and processing. This paper presents a low-complexity method for acoustic event detection and localizati…

Effect of Rotating Auditory Scene on Postural Control in Normal Subjects, Patients With Bilateral Vestibulopathy, Unilateral, or Bilateral Cochlear I…

2018

International audience; Objective: The aim of this study was to investigate the impact of a rotating sound stimulation on the postural performances in normal subjects, patients with bilateral vestibulopathy (BVP), unilateral (UCI), and bilateral (BCD cochlear implantees.Materials and Methods: Sixty-nine adults were included (32 women and 37 men) in a multicenter prospective study. The group included 37 healthy subjects, 10 BVP, 15 UCI, and 7 BCI patients. The average of age was 47 +/- 2.0 (range: 23-82). In addition to a complete audiovestibular work up, a dynamic posturography (Multitest Framiral, Grasse) was conducted in silence and with a rotating cocktail party sound delivered by headph…

Microphones’ Directivity for the Localization of Sound Sources

2011

In a recent paper [P. Rizzo, G. Bordoni, A. Marzani, and J. Vipperman, "Localization of Sound Sources by Means of Unidirectional Microphones, Meas. Sci. Tech., 20, 055202 (12pp), 2009] the proof-of-concept of an approach for the localization of acoustic sources was presented. The method relies on the use of unidirectional microphones and amplitude-based signals' features to extract information about the direction of the incoming sound. By intersecting the directions identified by a pair of microphones, the position of the emitting source can be identified. In this paper we expand the work presented previously by assessing the effectiveness of the approach for the localization of an acoustic…
