Voice-over to improve oral Production skills: the VICTOR project
(PUV, Publicacions Universitat de Valencia, 2018) Talaván Zanón, Noa; Rodríguez Arancón, Pilar; Sanderson Pastor, John D.; Botella Tejera, Carla
The assessment of the potential of audiovisual translation in foreign language education has been receiving increasing attention in the past few years. Although subtitling as a didactic tool is the modality that has been studied the most, research on revoicing techniques, such as dubbing and audiodescription is also starting to become the focus of attention. The VICTOR project was conceived as an attempt to assess the potential of yet another revoicing option that needed to be addressed: voice-over. Students enrolled in English C1 at the Online Foreign Language Centre of the Universidad Nacional de Educación a Distancia (UNED) volunteered to take part in this pilot experience and produced various revoiced versions of four videos (chosen among ten preselected clips) over the course of two months. The researchers analysed the experience through language assessment tests (related to improvement in pronunciation), questionnaires and observation. A YouTube channel was created to share and peer-review the tasks carried out and an adhoc rubric was designed to assess the revoicing work performed on the videos. The results are promising enough in terms of oral production skills improvement to encourage further research in the area.
Identification of age at death in red deer (Cervus elaphus) through the upper dentition: Eruption pattern, wear stage and crown heights
(Elsevier, 2024-03) Marín Hernando, Juan; Saladié i Ballesté, Palmira; Azorit Casas, Concepción; Rodríguez Hidalgo, Antonio; https://orcid.org/0000-0002-1730-8461; https://orcid.org/0000-0001-9538-7110; https://orcid.org/0000-0002-5449-9287
The present research aims to determine the age at which red deer (Cervus elaphus) specimens died by examining their upper dentition. We analyzed eighty free-ranging individuals from southern Spain to establish a reference database for age calculation. The age of these individuals was identified by the mandibular teeth inferred from their known death years and the maxillary teeth were evaluated relative to them. As a result, we have provided three non-destructive methods: a description of the eruption sequence and dental replacement, a referential code for occlusal wear stages, and a regression analysis considering the height of the cusps in both upper and lower dentition. These methods offer the possibility of estimating the age at which the animals died and categorizing them into specific age groups. To evaluate the practicality of this method, we applied it to the Middle Paleolithic archaeological site of Abric Romaní. All the proposed methods allow us to approximate the age at death of red deer individuals. The most accurate results, whenever feasible, are obtained by combining these different methods. This study facilitates the inclusion of upper dentition fossils that have traditionally been omitted from the analysis in archaeological sites, allowing a better adjustment of the quantitative methods used to calculate the number of skeletal elements and the number of individuals. This, in turn, enables a more accurate construction of the anatomical and mortality profiles
On the topological type of anticonformal square roots of automorphisms of even order of Riemann surfaces
(Springer, 2024-06-04) Costa González, Antonio Félix
Let S be a (compact) Riemann surface of genus greather that one. Two automorphism of S are topologically equivalent if they are conjugated by a homeomorphism. The topological classi cation of automorphisms is a classical problem and its study was initiated by J. Nielsen who in the thirties classi ed conformal ones. The case of anticonformal automorphisms is more involved and was solved by K. Yocoyama in the 80s-90s. In order to decide whether two anti-conformal automorphisms are equivalent, it is usually necessary to take into account many invariants, some of which are di cult to compute. In this work we present some situations where the topological equivalence is mainly due to the genus of some quotient surfaces and the algebraic structure of the automorphism group. An anticonformal square root of a conformal automorphism f is an anticonformal automorphism g such that g2 = f . Let g1 and g2 be anticonformal square roots of the same conformal automorphism of order m, where m is an even integer. If genus of S= hg1; g2i is even and genus of S= hgii is 6= 2 we prove that hg1i and hg2i are topologically equivalent. If genus of S= hg1; g2i is odd and hg1; g2i is abelian we obtain that hg1i and hg2i are topologically equivalent. We give examples to justify the condition genus of S= hgii 6= 2 and hg1; g2i abelian in each case.
