This descriptive research was undertaken to investigate the preferred channels of communication used in the adoption of livestock production practices by ranchers in the northeastern Mexican state of Nuevo Le??n. The study builds on previous research by Freund (1999). Freund??s study concluded that ranchers in Nuevo Le??n preferred the Uni??n Ganadera as their primary source. However, the producers indicated some communication preferences that resulted in the Uni??n adjusting some of their efforts to reach out to their membership. This study was designed to revisit those livestock producers to investigate what changes had occurred in their preferences for communication since the Freund (1999) study. This research was conducted in the state of Nuevo Le??n, Mexico. The methodology used was a survey employing a questionnaire to collect data. The convenience sample consisted of 273 active members of the Uni??n Ganadera Regional de Nuevo Le??n (UGRNL) who attended regularly scheduled association functions. A principal objective of the research was to describe the communication infrastructure used in the state of Nuevo Le??n by UGRNL livestock producers. Another objective of the research was to describe preferred formal and informal channels of communication that livestock producers use to get information about ranching practices. Yet another objective was to describe what UGRNL livestock producers use as primary sources of information when choosing to adopt or reject agricultural practices, as well as investigating what secondary and feedback channels they prefer. Another objective was to determine which husbandry practices UGRNL livestock producers want more information about. Finally, an emphasis of the study was on what communication channels smaller stakeholders prefer, because the Uni??n wants to use that information to improve its diffusion of technology to that particular group of producers.

My dissertation focuses on the life-writing produced by three authors from the first half of the XX century in Spain. These autobiographical texts were written by women who were part of the cultural and political scene of pre-civil war Madrid, and who lived in exile, mainly in Latin America countries - Cuba, Mexico, and Argentina. Each of these authors start the reconstruction of the past in three distinct ideological projects: philosophic in the case of María Zambrano (1904-1991); leftist political thought in the case of María Teresa León (1903-1988); and feminist in the case of Concha Méndez (1998-1986). An interdisciplinary theoretical framework forms the basis for my analysis of these texts. This includes the ideas of Sidonie Smith, Sylvia Molloy, and Beatriz Sarlo, and premises of Mikhail Bakhtin, specifically the relationship between the author and the characters in artistic production, and the representation of space and time, as understood under the concept of chronotope. Reading these autobiographies under those theoretical principles allows me to elaborate some ideas about what was it like to be a woman, writer, and intellectual in the same historical and political time period. At the same time, it promotes a discussion about the appropriation strategies and the resistance possibilities against the hegemonic discourses of the era, mainly those related to literary creation as well as gender representation.

The Leon River, a small-medium river in central Texas, is highly impacted by multiple impoundments, enrichment from agricultural runoff, and decreased dissolved oxygen levels. This degraded river contains sixteen unionid species, two of which are both endemic to the region and candidates for the federal endangered species listing (Quadrula houstonensis and Truncilla macrodon). While there is a short historical record for this river basin and a recent modern survey completed in 2011, zooarchaeological data adds evidence for conservation efforts by increasing the time depth of data available and providing another conservation baseline. Zooarchaeological data for the Leon River is available from the two Late Holocene archaeological sites: 41HM61 and the Belton Lake Assemblages. Data generated from these assemblages describe the prehistoric freshwater mussel community of the Leon River in terms of taxonomic composition and structure. By comparing this zooarchaeological data to the data generated by the longitudinal modern survey of the Leon River, long term changes within the freshwater mussel community can be detected. A conceptual model is constructed to evaluate how robusticity, identifiability, and life history ecology affect unionid taxonomic abundances in zooarchaeological data. This conceptual model functions as an interpretive tool for zooarchaeologists to evaluate forms of equifinality in zooarchaeological assemblages. This thesis determines differences between the late Holocene and modern freshwater community of the Leon River, explores how different alternative mechanisms influence zooarchaeological data, and exemplifies of how zooarchaeological data can be used for conservation biology.
