Migración contemporánea mexicana: redes sociales transnacionales y políticas migratorias : la experiencia migratoria de la comunidad de Tunkás, Yucatán en el sur de California

This research explores the impacts of the most recent U.S. economic crisis on the Mexican immigrant labour market, specifically from the town of Tunkás, Yucatan. Based on Bourdieu.’s theory of Capital production, and the transnational theoretical perspective, this study aims to build a conceptual frame for the migrant’s social capital in modern societies. A key element of this analysis is that a pioneer migrant-woman has initiated the tunkaseño social network in Los Angeles and Orange County, California; and has set the route to migrate to North. Finally this analysis presents how U.S. worksite enforcement policy affects the labour market that tunkaseños encounter in Southern California in the midst of a financial crisis. Tunkás, our Mayan community, native from the Southern Mexican state of Yucatan has experienced a constant migration process to California ever since the Bracero Program started. Mayan migrants have acquired new responsibilities, and a hybrid identity as transnational citizens. Yucatecan migration is defined as a contemporary Mexican migration, mostly undocumented, exacerbated during the nineties, in the midst of the Mexican financial crisis from 1994 to 1997. The present work is part of a broader research that discusses the transformation of Mexican migration patterns of different states of Mexico. This project is based on fieldwork in the communities of origin and destination. As well, on the survey results and life stories obtained during 2005-2006, and 2008-2009 by MMFRP1, where I took part in both editions as a researcher...

El audiovisual como herramienta de cambio social de jóvenes en situación de exclusión en Guatemala (2004-2014)

The audiovisual as a tool for social change among youth in social exclusion situations in Guatemala (2004-2014)” is the title of this research paper which aims to study the organizations and projects that have worked with video tools and participatory methodology with young people in marginalized social sectors in order to improve their opportunities and social inclusion. The purpose of this study also includes the analysis of the finish video products as well as the impact of the projects on the youth participants. Guatemala is a country with deep rooted and historical social inequality. This situation is currently reflected by the high violence rates, the extreme poverty and the exclusion of populations, including youth. As social participants, young people have much to say about the construction of a future plan for the country, but they are not heard. That’s why it is so important to facilitate a youth voice and research the tools that can help reach that goal. The participatory methodologies are based on the popular education theories developed by the Latinamerican School with authors such as Paulo Freire, Juan Díaz Bordenave, Jesús Martín Barbero and Mario Kaplún, among others. These methodologies have proved to be a lateral way to face the educational process by promoting dialogue, analysis, consensus search and consciousness-raising. In addition, these methodologies provide a more democratic way to format educational processes that provide students tools to promote an active attitude towards social questions. They can develop their own role of responsibility in the improvement of their own lives and contribute to the progress of their community. This research is based on observation, an extensive bibliographical review, analysis protocols for the study of video materials and projects and closed structured interviews with facilitators and project coordinators. It includes open qualitative interviews with some selected participants and with other specialists in order to complete the necessary information to structure the historical, social and political context of Guatemala...

The Climate-system Historical Forecast Project: do stratosphere-resolving models make better seasonal climate predictions in boreal winter?

Using an international, multi-model suite of historical forecasts from the World Climate Research Programme (WCRP) Climate-system Historical Forecast Project (CHFP), we compare the seasonal prediction skill in boreal wintertime between models that resolve the stratosphere and its dynamics (high-top') and models that do not (low-top'). We evaluate hindcasts that are initialized in November, and examine the model biases in the stratosphere and how they relate to boreal wintertime (December-March) seasonal forecast skill. We are unable to detect more skill in the high-top ensemble-mean than the low-top ensemble-mean in forecasting the wintertime North Atlantic Oscillation, but model performance varies widely. Increasing the ensemble size clearly increases the skill for a given model. We then examine two major processes involving stratosphere-troposphere interactions (the El Niño/Southern Oscillation (ENSO) and the Quasi-Biennial Oscillation (QBO)) and how they relate to predictive skill on intraseasonal to seasonal time-scales, particularly over the North Atlantic and Eurasia regions. High-top models tend to have a more realistic stratospheric response to El Niño and the QBO compared to low-top models. Enhanced conditional wintertime skill over high latitudes and the North Atlantic region during winters with El Niño conditions suggests a possible role for a stratospheric pathway.
