The musical production of Los Tigres del Norte and El Vez illustrates Mexican and Chicano/a traditions of using popular music as an alternative way of narrating Mexican immigrant, Chicano/a and Mexican American community life in the U.S.A. These musicians grapple with the ways in which a dominant U.S. national discourse has historically subordinated Mexican immigrant and Chicano/a communities. Through their lyrics these musicians propose—albeit in different ways—a progressive cultural politics that underscores the importance of equality and anti-discrimination based on ethnic, cultural, gender and class positions. This thesis compares the work of Los Tigres and El Vez and argues that, beyond the merely documenting and providing a narrative representation of Mexican immigrant and Chicano/a experiences in the U.S.A., these musicians must also be regarded as political activists, using their lyrics and musical profile to articulate and present alternative politics on behalf of Mexican immigrants and Chicano/as in the U.S., and in ways that work with the legacies of the Chicano Movement in the 1960s and 1970s. In this thesis I attend to the differences between El Vez and Los Tigres del Norte. The musicians come from distinct musical and performance backgrounds, and work with distinct generic musical praxes. While recognizing those differences, I nonetheless identify five comparable axes of progressive politics in their work. First, they counter the notion that Mexican immigrant, Chicano/a and Mexican American communities in the U.S.A. form one homogenized group. Second, they emphasize community building as a form of empowerment for immigrant groups and ethnic minorities. Third, they continue the Chicano Movement fight for human rights and equality; but rather than calling for a separate nation of Aztlán, Los Tigres del Norte and El Vez claim a place for Mexican immigrants and Chicano/as as viable and productive constituencies in the U.S.A. Four, though these artists are male performers, they also deal with gendere issues and female characters and thus do not uphold the subordinate role of women in Mexican immigrant and Chicano/a patriarchal societies. And five, Los Tigres del Norte and El Vez engage with notions of an “America” whose pan-ethnic and trans-national qualities reflect the musicians’ advocacy of alliances between diverse subordinate groups. Such engagements demonstrate that Los Tigres del Norte and El Vez operate as political activists whose lyrics and musical profile confirm the lasting impact of Chicano Movement activist aspirations, while also reworking those aspirations in line with changing sociopolitical conditions.

Esta tesis trata de la arquitectura de los años treinta en el país vasco, enmarcándola en el contexto de la arquitectura española y europea de aquellos años. Una vez recogido el material, la mayoría inédito y colocado en su lugar cronológico, se analizo, presentándose dicho análisis en un texto con estructura propia. Dicho texto se expuso organizado en programas. Previamente a dicho núcleo, que constituye el núcleo fundamental de la tesis, se enmarca dicha arquitectura en el contexto arquitectónico internacional. Y la tesis se remata con un conjunto de documentos, la mayoría inéditos que constituyen los anexos entre los cuales destaca la correspondencia entre los grupos norte y este del G.A.T.E.P.A.C. que se acompaña con notas.La organización en programas me permitió trabajar con cierto rendimiento mediante el uso del método comparado.Sumariamente, se trataba de comparar los distintos procedimientos compositivos y despliegues de estructuras técnicas, verdaderos núcleos de la operación arquitectónica, ante programas semejantes. El análisis formal de las obras me permitió inducir mecanismos y criterios que de una u otra forma se encontraban en los proyectos y obras de dicho periodo. Todo ello me permitió caracterizar la arquitectura de dicha época en el país vasco.

This study examines online news production through a cross-national comparative ethnography of two newsrooms: The Chicago Tribune in Chicago, Illinois and El Norte in Monterrey, Mexico. The researcher looks specifically at the extent of collaborative group work in the online newsroom. First, the researcher investigates the degree to which online newsrooms operate organizationally as collaborative groups when producing content for the website, as opposed to functioning individualistically when producing content for the website. The second facet examined is the cultural variability (Hofstede, 1980) of collaboration in the two online newsrooms, particularly whether the United States and Mexican online newsrooms support a collectivistic or individualistic and a high-context or low-context culture schema (Hofstede, 1980; Hall 1976). The last facet explored is how the collaborative behavior of the journalists in the two newsrooms supports or interferes with the practice of journalistic principles of verification and comprehensiveness and if this helps to make journalism better. This study found the El Norte newsroom has a collectivistic and high-context communication culture whereas The Chicago Tribune newsroom has an individualistic and low-context communication culture. Both newsrooms support the principles of verification and context in the news that is produced for the Website that helps to make the news accurate and comprehensive. It can be inferred, however, that the collectivistic, high-context communication culture is more supportive of a collaborative work environment that is conducive to making the journalists work together to help make the news accurate and comprehensive for the public. When the news is accurate and comprehensive, the public has better-informed citizens to make decisions in their daily lives as part of a democratic society. This study also has implications for the journalism and business industry as to the benefits of collaborative groupwork on the service or product outcome in an organization. / text

En el presente trabajo de tesis referido al mineral M1 de leyes de cabeza de oro bajas, entre 0,4 y 0,6 gr Au/t, se realizaron dos series de pruebas para determinar la influencia de las variables operativas en la lixiviación en columnas, como tamaño de partícula del mineral, concentración de cianuro, tasa de riego y ciclo de lixiviación. Se muestreó mineral del tajo de la mina y se dio la granulometría requerida para las pruebas, adicionándole cal en un ratio de 0,5 kg/t de mineral para asegurar un pH básico. Se pesó y cargó el mineral chancado a las columnas de 0,3048 m (12 pulgadas) de diámetro por 3 m de altura que fueron regadas con solución de cianuro de sodio a las concentraciones determinadas en el diseño experimental compuesto. Los resultados de las pruebas experimentales determinaron la significancia de cada variable, encontrando que la granulometría no tiene una influencia directa sobre el nivel de recuperación de oro, mientras que si tienen alto impacto: la tasa de riego, la concentración de cianuro y el ciclo de lixiviación. Por lo que se puede decir que estas tres últimas variables: tasa de riego, concentración de cianuro y el ciclo de lixiviación influyen significativamente en la recuperación de oro del mineral M1 de la Minera Barrick Misquichilca en su operación de Lagunas Norte.
