Weblogs éducatifs pour l’enseignement d’une Langue Etrangère
Mario Tomé
Synergies Espagne , 2009,
Abstract: Dans les weblogs du Campus Virtuel FLE de l’université de León des recherches et des expérimentations sont menées en rapport avec l’enseignement/apprentissage du fran ais langue étrangère, notamment en relation avec le développement des compétences de production orale chez les étudiants espagnols. Les résultats des applications pédagogiques des weblogs en classe de fran ais et leur analyse permettent une réflexion sur leurs potentiels didactiques dans les nouveaux contextes éducatifs du web 2.0.

Abstract: This study focuses on learning pronunciation within the study of French as a foreign language (FLE) with the help of resources and tools of the web 2.0. The investigation was carried out both in the classroom and online (Campus Virtuel FLE, Universidad de León) and 178 students (mainly beginner level) have participated in it between 2005 and 2009. Firstly, we wanted to analyze the characteristics and modalities of different oral productions from students, as well as ICT tools and teaching tasks which have encouraged the creation of audiovisual recordings published in several educational web environments (weblogs, podcasts, social networking, education platform).We have also attempted to assess the reactions of students to the application of these tools, learning environments and pronunciation tasks, by carrying out three surveys which focus on their ICT skills and pronunciation within FLE. Finally we asked about the role which students, tutors and teachers play in the correction of pronunciation, taking into consideration the feedback strategies that have been observed in their interaction, with special emphasis on autocorrective feedback such as in collaborative pronunciation tasks corrected by the students. Este estudio se centra en el aprendizaje de la pronunciación del francés lengua extranjera (FLE) con la utilización de los recursos y herramientas de la web 2.0. La investigación se ha llevado a cabo dentro de un dispositivo de ense anza presencial y a distancia (Campus Virtuel FLE, Universidad de León), en el que han participado 178 alumnos (principalmente de nivel débutant) entre los cursos 2005 y 2009. Se han seleccionado los entornos web y las tareas pedagógicas que han resultado más efi caces para el desarrollo de las competencias orales de los alumnos de FLE. Nuestra experimentación se ha centrado especialmente en sus producciones orales que han sido grabadas en distintos suportes digitales audio y video. Las estrategias de feedback para la corrección de la pronunciación constituyen un factor fundamental y de modo particular las prácticas colaborativas entre los alumnos. Los resultados obtenidos ponen de relieve aspectos cuantitativos (incremento de las producciones orales en el espacio de la clase y en los distintos entornos web: weblogs, podcast, redes sociales, plataforma de ense anza), así como cualitativos, relacionados la implicación de los alumnos en los distintos contextos de aprendizaje de la pronunciación (autocorrecciones y correcciones colaborativas).

Mario Tomé
?édille : Revista de Estudios Franceses , 2007,
Abstract: Les weblogs, carnets web, cybercarnets ou blogs, en fran ais journal du web , constituent une alternative à la publication de pages web et ils ont été utilisés par les internautes comme un moyen d’expression de leurs idées, opinions ou créations. Un carnet web (weblog) est, littéralement, un journal de bord (log) sur la toile (web), organisé chronologiquement et permettant les réactions au contenu publié, grace à la fonction Commentaries .
Enseignement des langues, communication et compétences orales sur le web actuel
Mario Tomé
?édille : Revista de Estudios Franceses , 2009,
Abstract: The application of new technologies in language teaching opens up a range of options in the search for methods and tools favourable to both effective foreign language acquisition and knowledge of its culture. In spite of the expansion on the Internet of audiovisual tools that enhance communication, oral production strategies are still poorly developed in the language classroom. Within the framework of pedagogical telecollaboration projects, written language is usually predominant. The León-Grenoble project and the communities of practice in the Campus Virtuel FLE try to correct these discrepancies by trying to establish a balance between oral and written skills. Task-based oral production is here fundamental for learners of French as a Foreign Language (FFL). And even more crucial are the practices to correct pronunciation for the three agents involved in the educational context: teachers, tutors and students of FFL.
L'enseignant de FLE et les ressources Internet

?édille : Revista de Estudios Franceses , 2006,
Abstract: This article present the role of the teacher in the new contexts of formation opened by new information technologies and communication (in particular Internet) within the framework of the numerical universities or the virtual campuses. This article proposes in also a classification of the teaching resources in relation to the supports and the devices not to confuse the various materials which make part of Internet. The many resources, supports and achievements announced in this ar ticle and available on line can give tracks to teachers and researchers in the field of the TICE.
Triebel-Lizorkin spaces on metric spaces via hyperbolic fillings
Mario Bonk,Eero Saksman,Tomás Soto
Mathematics , 2014,
Abstract: We give a new characterization of (homogeneous) Triebel-Lizorkin spaces $\dot{\mathcal F}^{s}_{p,q}(Z)$ in the smoothness range $0 < s < 1$ for a quite general class of metric measure spaces $Z$. The characterization uses Gromov hyperbolic fillings of $Z$. This gives a short proof of the quasisymmetric invariance of these spaces in case $Z$ is $Q$-Ahlfors regular and $sp = Q > 1$. We also obtain first results on complex interpolation for these spaces in the metric space framework.
Genome-Wide Functional Divergence after the Symbiosis of Proteobacteria with Insects Unraveled through a Novel Computational Approach
Christina Toft,Tom A. Williams,Mario A. Fares
PLOS Computational Biology , 2009, DOI: 10.1371/journal.pcbi.1000344
Abstract: Symbiosis has been among the most important evolutionary steps to generate biological complexity. The establishment of symbiosis required an intimate metabolic link between biological systems with different complexity levels. The strict endo-cellular symbiotic bacteria of insects are beautiful examples of the metabolic coupling between organisms belonging to different kingdoms, a eukaryote and a prokaryote. The host (eukaryote) provides the endosymbiont (prokaryote) with a stable cellular environment while the endosymbiont supplements the host's diet with essential metabolites. For such communication to take place, endosymbionts' genomes have suffered dramatic modifications and reconfigurations of proteins' functions. Two of the main modifications, loss of genes redundant for endosymbiotic bacteria or the host and bacterial genome streamlining, have been extensively studied. However, no studies have accounted for possible functional shifts in the endosymbiotic proteomes. Here, we develop a simple method to screen genomes for evidence of functional divergence between two species clusters, and we apply it to identify functional shifts in the endosymbiotic proteomes. Despite the strong effects of genetic drift in the endosymbiotic systems, we unexpectedly identified genes to be under stronger selective constraints in endosymbionts of aphids and ants than in their free-living bacterial relatives. These genes are directly involved in supplementing the host's diet with essential metabolites. A test of functional divergence supports a strong relationship between the endosymbiosis and the functional shifts of proteins involved in the metabolic communication with the insect host. The correlation between functional divergence in the endosymbiotic bacterium and the ecological requirements of the host uncovers their intimate biochemical and metabolic communication and provides insights on the role of symbiosis in generating species diversity.

Revista médica de Chile , 2007,
Abstract: Background: The socioeconomic position (SEP) and educational level of individuals have an inverse correlation with mortality in developed societies. Aim To assess in a society undergoing a socioeconomic transition, the mortality risk associated to a low SEP (combination of education and income, scale 0-25 points, reference > 10 points) and low education (education years, reference > 8 years), adjusting for other known risk factors. Material and methods: In this prospective cohort study, a random sample of 920 subjects, living in San Francisco de Mostazal, Chile, aged more than 20years (395 males) was examined for the first time in 1997-1999 and re-examined in 2005-2006. All had information about economic household income and level of education. A Cox regression model was used to evaluate the association between mortality and socioeconomic measures. Results: The crude mortality hazard ratio (HR) was 3.34 (95% confidence interval (CI) 2.88-3.87) and 6.05 (95% CI 5.04-7.26) for low SEP and low educational level, respectively. After adjusting for age, gender, hypertension, diabetes, dyslipidemia, abdominal obesity, smoking, alcohol intake and family history of cardiovascular disease, the figures were 1.23 (95% CI 1.04-1.43) and 1.54 (95% CI 1.23-1.85) for low SEP and low educational level, respectively. Conclusions: In a society in socioeconomic transition, low SEP and especially low educational level are risk factors for mortality even after adjusting for known mortality risk factors
