Elektrophysiologische Untersuchung zum Einsatz von Streptolysin O und Natrium-Hyaluronat zur Permeabilitätsmodulation der Membran des runden Fensters…
2003
Background: The round window membrane (RWM) acts like a barrier for topically applied substances into the middle ear preventing diffusion into the perilymphatic fluid compartment. Material and Method: In an animal model, modulation of the permeability of the RWM was attempted using Streptolysin-O (SLO) in various concentrations and sodium hyaluronate. Thereafter, the effect of intratympanically applied Lidocain 2% on hearing threshold measured by auditory brainstem response was tested for Lidocain 2 % and Lidocain 2 % in combination with SLO or sodium hyaluronate. Results: The results show that both, SLO and sodium hyaluronate, influence the effect of Lidocain 2 % on hearing thresholds as a…
Factores que determinan los honorarios de auditoría: Análisis empírico para México
2012
La escasa investigación internacional sobre auditoría en el ámbito latinoamericano ha motivado el desarrollo de esta investigación. El objetivo de este trabajo es analizar empíricamente los factores que influyen en el monto de los honorarios de auditoría en México, partiendo de una muestra de 59 empresas que cotizan en la Bolsa Mexicana de Valores (BMV), durante el período de 2002 a 2008. La metodología empleada, en línea con los estudios previos, se basa en un modelo de regresión múltiple, a partir de un conjunto de hipótesis relacionadas con diversos factores que afectan la determinación de los honorarios, vinculados a la empresa auditada y a la firma auditora, recolectados de la base de …
Pedagogical approaches for e-assessment with authentication and authorship verification in Higher Education
2019
Checking the identity of students and authorship of their online submissions is a major concern in Higher Education due to the increasing amount of plagiarism and cheating using the Internet. The literature on the effects of e-authentication systems for teaching staff is very limited because it is a novel procedure for them. A considerable gap is to understand teaching staff' views regarding the use of e-authentication instruments and how they impact trust in e-assessment. This mixed-method study examines the concerns and practices of 108 teaching staff who used the TeSLA—Adaptive Trust-based e-Assessment System in six countries: the UK, Spain, the Netherlands, Bulgaria, Finland and Turkey.…
Oscillatory Dynamics Underlying Perceptual Narrowing of Native Phoneme Mapping from 6 to 12 Months of Age
2016
During the first months of life, human infants process phonemic elements from all languages similarly. However, by 12 months of age, as language-specific phonemic maps are established, infants respond preferentially to their native language. This process, known as perceptual narrowing, supports neural representation and thus efficient processing of the distinctive phonemes within the sound environment. Although oscillatory mechanisms underlying processing of native and non-native phonemic contrasts were recently delineated in 6-month-old infants, the maturational trajectory of these mechanisms remained unclear. A group of typically developing infants born into monolingual English families, …
Comprehensive auditory discrimination profiles recorded with a fast parametric musical multi-feature mismatch negativity paradigm
2016
Abstract Objective Mismatch negativity (MMN), a component of the auditory event-related potential (ERP) in response to auditory-expectancy violation, is sensitive to central auditory processing deficits associated with several clinical conditions and to auditory skills deriving from musical expertise. This sensitivity is more evident for stimuli integrated in complex sound contexts. This study tested whether increasing magnitudes of deviation (levels) entail increasing MMN amplitude (or decreasing latency), aiming to create a balanced version of the musical multi-feature paradigm towards measurement of extensive auditory discrimination profiles in auditory expertise or deficits. Methods Usi…
Sporta spēļu nacionālo čempionātu videotiešraižu pieprasījums un piedāvājums Latvijas interneta un televīzijas vidē
2015
Bakalaura darba ''Sporta spēļu nacionālo čempionātu videotiešraižu pieprasījums un piedāvājums Latvijas interneta un televīzijas vidē'' mērķis ir noskaidrot, cik liels ir mediju videotiešraižu piedāvājums un auditorijas pieprasījums pēc nacionālo sporta spēļu čempionātu translācijām, kā arī, kādi faktori ietekmē to, ka aizvien vairāk translāciju veido interneta tiešraižu kompānijas, bet tradicionālās televīzijas to dara retāk. Darba teorētiskā daļa ietver teoriju par pieprasījumu un piedāvājumu, televīzijas un jauno mediju ietekmi sporta dzīvē, kā arī auditorijas lomu sportā un mediju darbībā. Metodoloģija ietver ekspertu intervijas, sekundāro datu analīzi un dziļās intervijas ar sporta aud…
Electrophysiological and hemodynamic mismatch responses in rats listening to human speech syllables
2016
International audience; Speech is a complex auditory stimulus which is processed according to several time-scales. Whereas consonant discrimination is required to resolve rapid acoustic events, voice perception relies on slower cues. Humans, right from preterm ages, are particularly efficient to encode temporal cues. To compare the capacities of preterms to those observed in other mammals, we tested anesthetized adult rats by using exactly the same paradigm as that used in preterm neonates. We simultaneously recorded neural (using ECoG) and hemodynamic responses (using fNIRS) to series of human speech syllables and investigated the brain response to a change of consonant (ba vs. ga) and to …
Otitis media with effusion in children: Cross-frequency correlation in pure tone audiometry.
2019
Different guidelines are adopted in clinics and countries to assess pure tone hearing sensitivity in children with otitis media with effusion (OME). Some guidelines specify a broad range of audiometric frequencies that must be tested and from which average thresholds determined, while others leave test frequencies unspecified. For guidelines that suggest specific frequencies there are various pure tone frequencies and frequency ranges given. The present study investigated whether (1) a full range of audiometric frequencies is required to evaluate hearing loss caused by OME in children, or if neighboring frequencies provide essentially the same threshold information, and (2) if different com…
Reading Disabilities in children with Specific Language Impairment
2019
El presente estudio examinó el rendimiento en lectura de los niños con Trastorno Específico del Lenguaje (TEL). Treinta niños con TEL y 32 niños con desarrollo normal del lenguaje, equilibrados en género, edad cronológica e inteligencia, fueron evaluados mediante el PROLEC-R. Los resultados de los ANOVAs indicaron que ambos grupos difieren en el rendimiento en lectura. Como grupo, los niños con TEL tuvieron significativamente un rendimiento inferior, tanto en la exactitud como en el tiempo de la lectura de palabras y pseudopalabras, por lo que tenían una menos eficacia de lectura. En la misma línea, el rendimiento de los niños con TEL en comprensión literal e inferencial también fue inferio…
Mismatch negativity (MMN) in freely-moving rats with several experimental controls.
2014
Mismatch negativity (MMN) is a scalp-recorded electrical potential that occurs in humans in response to an auditory stimulus that defies previously established patterns of regularity. MMN amplitude is reduced in people with schizophrenia. In this study, we aimed to develop a robust and replicable rat model of MMN, as a platform for a more thorough understanding of the neurobiology underlying MMN. One of the major concerns for animal models of MMN is whether the rodent brain is capable of producing a human-like MMN, which is not a consequence of neural adaptation to repetitive stimuli. We therefore tested several methods that have been used to control for adaptation and differential exogenou…
