Sur l’importance des disques et du recording dans la musique populaire et la techno
2005
International audience; Depuis qu'Edison a inventé le phonographe un nouveau mode de stockage de la musique est venu s'ajouter au corps des individus et à la notation : les disques. Cela signifie, qu'en plus d'aller à la musique (jouer d'un instrument ou assister à un évènement musical), la musique vient à nous. C'est donc par l'intermédiaire des enregistrements que, dans une très grande mesure, nous découvrons, aimons, apprenons et transmettons la musique. Autrement dit, ce que l'on appelait jadis, et assez improprement, la culture orale, a trouvé son médium, un objet léger et bourré d'informations précieuses qui circule et s'échange facilement.
Inhibitory effect of A10 dopaminergic neurons of the ventral tegmental area on the orienting response evoked by acoustic stimulation in the cat.
1998
Abstract The effect of bilateral electric stimulation of A10 dopaminergic neurons of the ventral tegmental area (80–300 μA, 20–50 Hz, 0.1–0.5 ms, 2 s duration) on latency and duration of the orienting response, evoked by acoustic stimuli (4500–8000 Hz, 2 s), was studied in the cat. A10 neuron stimulation, simultaneous with the acoustic one, was performed with threshold parameters inducing minimal behavioral signs (head searching movement, sniffing, increase in alertness). By means of a videoanalysis system, a statistically significant increase, both of latency and duration of the response, was observed. The possible role of dopamine was studied administrating sulpiride (20 mg/kg IP), a dopa…
Audiogrāmata Latvijā: publisko bibliotēku bibliotekāru viedoklis
2018
Audiogrāmatas latviešu valodā, laika gaitā izmantojot dažādus skaņas nesējus, tiek regulāri izdotas, tomēr tās ir maz pētītas kā pastāvīgs grāmatas formāts. Bakalaura darba mērķis ir noskaidrot Latvijas publisko bibliotēku bibliotekāru viedokli par audiogrāmatām kā bibliotēku krājuma sastāvdaļu, kā arī bibliotekāru personīgo pieredzi attiecībā uz šāda formāta grāmatu izmantošanu. Darba teorētiskajam pamatojumam izvēlēta aksioloģija jeb vērtību teorija, kā arī Inovāciju difūzijas teorija. Dati iegūti, pielietojot kvantitatīvo un kvalitatīvo metodi – veicot anketēšanu un atsevišķu jautājumu tālākai izpētei izmantojot daļēji strukturētās intervijas. Pētījuma rezultāti parāda, ka apmeklētāju in…
Domain‐specific neural networks improve automated bird sound recognition already with small amount of local data
2022
1. An automatic bird sound recognition system is a useful tool for collecting data of different bird species for ecological analysis. Together with autonomous recording units (ARUs), such a system provides a possibility to collect bird observations on a scale that no human observer could ever match. During the last decades, progress has been made in the field of automatic bird sound recognition, but recognizing bird species from untargeted soundscape recordings remains a challenge. 2. In this article, we demonstrate the workflow for building a global identification model and adjusting it to perform well on the data of autonomous recorders from a specific region. We show how data augmentatio…
Theatrical virtual acoustic rendering with head movement interaction
2019
AbstractNowadays, the use of virtual reality/virtual acoustics (VR/VA) in archaeology for rendering lost buildings is an important topic in the cultural heritage field. Moreover, the addition of additional senses apart from the sight increases the feeling of immersion in virtual environments. The aim of this paper is to show the interaction work developed in a VA system, based on Unity and FMOD, the graphical and acoustical reconstruction of an ancient building and the development of a VR goggles with headphones to render 3D audio and video interactively. This system has been implemented to render auralizations in a binaural system and has been applied to the renderization of an old and los…
Client documents in social work with adults as research data : scoping review of opportunities and challenges
2022
Documentation is an integral part of social work. It is a tool in client work, and it also has an accountability perspective. Documentation helps the practitioners to evaluate their own work and makes it possible to assess the impact of work and develop practices. The use of client documents for research purposes has been identified as an option, but it is still quite rare. Moreover, little attention has been paid to social work with adults in this context. The development of electronic information systems (EIS), including structured forms, presents new research opportunities. Through documentation, it is possible to make tacit information visible and obtain evidence, for example, about the…
Photosensitive polyurethanes for optical record
2011
The method of synthesis of photosensitive polyurethanes polymers on glycerine, toluenediisocyanate and Disperse Red 1 base has been described. Two types of polymers with different amount of Disperse Red 1 fragments in macromolecules were compared. Films of the polymers were obtained from solutions in organic solvents on glass substrate. The dry film thickness was in the range of 3,5 - 4.5 μm. The transmission spectrums of the films were studied. Possibility of formation of side product in the process of synthesis was observed. The photobirefringence measurements of polymers films were performed. Surface relief grating (SRG) formation was observed during polarization holographic recording pr…
Optical Field-Induced Mass Transport in Soft Materials
2013
Abstract The dependence of the surface relief formation in amorphous chalcogenide (As 2 S 3 and As-S-Se) and Disperse Red 1 dye grafted polyurethane polymer films on the polarization state of holographic recording light beams was studied. It is shown that the direction of lateral mass transport on the film surface is determined by the direction of light electric vector and photoinduced anisotropy in the film. We propose a photoinduced dielectropfhoretic model to explain the photoinduced mass transport in amorphous films. Model is based on the photoinduced softening of the matrix, formation of defects with enhanced or decreased polarizability, and their drift under the electrical field gradi…
Is It Possible to Educate, Intervene or “Cure” Autism Spectrum Disorder? A Content Analysis of YouTube Videos
2021
YouTube es uno de los sitios web más conocidos y de mayor acceso en todo el mundo, por lo que tiene un gran potencial pedagógico. No obstante, la calidad y la veracidad de algunos videos de YouTube son cuestionables. Las dudas sobre la confiabilidad del contenido fáctico es un factor controvertido que debe tenerse en cuenta, especialmente cuando se abordan cuestiones de salud pública. Por ello, el principal objetivo de este trabajo es analizar el contenido de los vídeos en español más vistos en YouTube relacionados con el trastorno del espectro autista (TEA). Para la realización de esta investigación se utilizaron los términos "autismo Y educación", "autismo Y intervención" y "autismo Y cur…
Removing ocular artifacts from magnetoencephalographic data on naturalistic reading of continuous texts
2022
Naturalistic reading paradigms and stimuli consisting of long continuous texts are essential for characterizing the cortical basis of reading. Due to the highly dynamic nature of the reading process, electrophysiological brain imaging methods with high spatial and temporal resolution, such as magnetoencephalography (MEG), are ideal for tracking them. However, as electrophysiological recordings are sensitive to electromagnetic artifacts, data recorded during naturalistic reading is confounded by ocular artifacts. In this study, we evaluate two different pipelines for removing ocular artifacts from MEG data collected during continuous, naturalistic reading, with the focus on saccades and blin…
