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...

Remaking Movie Making: The Environmental Impacts of the Film Industry in Southern California

The film and television industry is integral to the economics and culture of the Southern California region. It is also a major contributing factor to the environmental problems in the region. Currently the Motion Picture, Television, and Commercial Industries Act of 1984 is the only regulation written specifically for the entertainment industry. This regulation was created with the purpose of streamlining the film permitting process to prevent run-away production, taking production out of state, and encourage growth. A change in this regulation is needed since studios routinely fail to meet environmental standards or work towards improvement during on-location filming. Amendments to this regulation requiring permits to contain environmental conditions would improve environmental conditions and stay true to the original purpose of the act.

Development of a Cleanup Management Plan for the San Benito River in San Benito County, California

Trash and car/truck bodies in the San Benito River and along its banks continue to present a challenge as state mandated basin plans often fail to address these pollutants. To measure the extent of the problem, an assessment of trash and car/truck bodies was completed along four locations of the river. The survey results indicated a need for a Cleanup Management Plan that should include a streamlining process for the removal of car/truck bodies, as well as guidelines for river cleanups. Existing cleanup plans and internet resources were analyzed for creation of the Cleanup Management Plan for the San Benito River.

Comparación de las macroalgas epizóicas de la madreperla Pinctada mazatlanica (Hanley 1856) con las de fondos rocosos en la bahía de La Paz, Baja California Sur, México

El presente estudio describe la comunidad de macroalgas epizóicas de Pinctada mazatlanica y la compara con la del substrato rocoso. Colectamos un total de 36 muestras de la comunidad de macroalgas, 18 muestras sobre ostras y otras tantas sobre substrato rocoso en la Península San Juan Nepomuceno, bahía de La Paz, México. Las algas fueron colectadas mediante buceo SCUBA raspando las distintas superficies (25 cm2 de substrato rocoso). El tamaño de muestra fue ajustado por curva de acumulación de especies y expresado con un modelo polinomial. Comparamos las comunidades de algas con análisis multivariantes de similitud basados en el índice de Bray-Curtis, entre substratos, diferentes alturas de ostras perleras y profundidades. Encontramos 27 especies de algas epizóicas (15.4% Clorophyta, 3.8% Phaeophyta y 80.8% Rhodophyta) con una disimilitud de 71.16% con respecto al substrato rocoso. El dendrograma mostró tres agrupaciones de macroalgas en P. mazatlanica. El primero caracterizado por Chondria, Jania, Herposiphonia tenella y Gracilaria. El segundo compuesto por Jania, Polysiphonia acuminata, P. decusata y Spyridia filamentosa. El tercero constituido por Polysiphonia sp., Jania, Herposiphonia tenella, Ceramium canouii y Amphiroa sp. Estas agrupaciones y los talos filamentosos de las algas epizóicas corresponden a estados iniciales de sucesión.
