El presente artículo tiene como propósito revelar las tendencias y desafíos de los programas de posgrado latinoamericanos ante la inminente situación de educación confinada por efecto del COVID-19. Se ha optado por la modalidad de investigación documental mediante la sistematización y análisis de fuentes bibliográficas, hemerográficas y referenciales. Los resultados en cuanto a tendencias se agruparon en tres categorías: la gestión, la investigación y el desarrollo curricular; siendo que los mayores desafíos apuntan al mejoramiento de la calidad con currículos transdisciplinarios, e investigaciones pertinentes y colaborativas a nivel regional, así como el aseguramiento de capacidades tecnológicas sustentables. Se concluye que la pandemia ha significado un punto de inflexión en la evolución del sistema universitario latinoamericano, y ante ello los posgrados tienen el reto de “innovar-se”, para lo cual deben evaluar los efectos académicos y gerenciales que han sido vivenciados durante el confinamiento, a los fines definir y adecuar los modelos de gestión, de investigación y los diseños curriculares en atención a los emergentes perfiles profesionales que el nuevo entorno pospandémico está avizorando
Breathy voice quality is frequently encountered in both normal and dysphonic voices. Breathiness has been associated with an increase in the intensity of aspiration noise as well as changes in spectral slope [Childers and Ahn, 1995; Fischer-Jorgenson, 1967; Huffman, 1987; Klatt and Klatt, 1990]. Shrivastav and Sapienza (2003) found that subjective ratings of breathiness obtained from a group of listeners were highly correlated with certain measures calculated from the auditory spectrum of the vocal acoustic signal. One of these measures, the partial loudness of the harmonic energy, was related to both the aspiration noise and the spectral slope of the voices. In the present experiment, 10 young adult listeners with normal hearing were presented with voices that varied systematically in terms of their aspiration noise and spectral slope. The stimuli, five male and five female voices, were generated using the Klatt synthesizer and were modeled after naturally occurring voices. Listeners rated breathiness for each of these stimuli using a 7-point rating scale. Results show the relative contribution of spectral slope and aspiration noise to the perception of breathiness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
