Para ello, se empleó una metodología mixta utilizando entrevistas semi estructuradas y una encuesta con la finalidad de conocer la aceptación del MMFD. De esta manera se identificó una articulación entre educación-empleo y que el MMFD genera e incentiva nuevas dinámicas. Asimismo, se observaron efectos como el desarrollo de competencias por parte de los egresados y las prácticas de las empresas y el alcance en la empleabilidad por parte de los egresados. Se exponen conclusiones y recomendaciones para su aplicación en México.

Argentinian cinema for your part has been characterized by a sentimentality dyed of certain humor. Both of them have resorted to the stereotypes and to a unidimensional vision. Nevertheless, in spite of the fact that there are very different contexts, nowadays cinematographic productions of both countries tend to complicate the subject matter, to show other aspects, besides poverty and dictatorships, which motivate migration and lack of integration. In some recent movies a decrease of the fictional aspect is observed in favour of an almost documentary approach. In others there is a change of kind: "drama" is left behind and they are catalogued as " dramatic comedies " and even romantic comedies or simply movies of great comedy.The main purpose of this article is to expose these changes and their motivations.

The speaker variation is then learned from the training data. However, human perception can differentiate speakers by age, gender, among other characteristics. In this paper, we investigate a speaker-type informed model that explicitly captures the known variation of speakers. We explore a mixture of three PLDA models, where each model represents an adult female, male, or child category. The weighting of each model is decided by the prior probability of its respective class, which we study. The evaluation is performed on a subset of the BabyTrain corpus. We examine the expected performance gain using the oracle speaker type labels, which yields an 11.7% DER reduction. We introduce a novel baby vocalization augmentation technique and then compare the mixture model to the single model. Our experimental result shows an effective 0.9% ...

The system outputs the ensemble results of the five subsystems: two x-vector-based subsystems, two end-to-end neural diarization-based subsystems, and one hybrid subsystem. We refine each system and all five subsystems become competitive and complementary. After the DOVER-Lap based system combination, it achieved diarization error rates of 11.58% and 14.09% in Track 1 full and core, and 16.94% and 20.01% in Track 2 full and core, respectively. With their results, we won second place in all the tasks of the challenge.

In contrast to the conventional pipeline approach to speaker diarization, EEND methods are better in terms of speaker overlap handling. However, EEND still has a disadvantage in that it cannot deal with a flexible number of speakers. To remedy this problem, we introduce encoder-decoder-based attractor calculation module (EDA) to EEND. Once frame-wise embeddings are obtained, EDA sequentially generates speaker-wise attractors on the basis of a sequence-to-sequence method using an LSTM encoder-decoder. The attractor generation continues until a stopping condition is satisfied; thus, the number of attractors can be flexible. Diarization results are then estimated as dot products of the attractors and embeddings. The embeddings from speaker overlaps result in larger dot product values with multiple attractors; thus, this method can deal with speaker overlaps. Because the maximum num...

There is a discrepancy between centers and countries in terms of incidence data of infection-disease in this population of patients. Design: an analytical observational study was conducted, taking a retrospective cohort of patients older than 18 years old, kidney transplant recipients of living or cadaveric donors between 2004 and 2015, with at least 6 months of follow-up. Material and methods: non-probability convenience sampling was done; data from the clinical records of the kidney transplant patients were taken, calculating the incidence density of CMV infection-disease and the clinical and demographic characteristics of the patients who presented these pathologies were described.
