A Cross-Cultural Study of Adult Attachment, Social Self-Efficacy, Familismo, and Psychological Wellbeing (open access)

A Cross-Cultural Study of Adult Attachment, Social Self-Efficacy, Familismo, and Psychological Wellbeing

Although Latinos are the largest minority group in the country, research examining how different psychological and cultural variables affect Latino individuals' wellbeing is disproportionately developed and cross-cultural comparison studies are particularly scarce. To address these issues, this dissertation research examined cross-cultural adult attachment-social self-efficacy-psychosocial wellbeing conceptual mediational model while investigating the moderator effects of country membership and familismo on the proposed mediational model using a cross-cultural sample of Mexican and Mexican-American university students. A total of 595 participants, including 360 Mexican students from Mexico and 235 Mexican-American students from the United States completed the research questionnaires. Results indicated that social self-efficacy was a significant mediator for the effects of insecure attachment on life satisfaction and conflict resolution in both cultural groups and for the links between attachment insecurity and depressive symptoms in the Mexican-American group. Additionally, moderated mediation analyses showed that country membership was a significant moderator for the links between attachment avoidance and social self-efficacy when life satisfaction, conflict resolution style, and depressive symptoms were the dependent variables, as well as for the direct link between attachment anxiety and physical health symptoms. Familismo was also found to be a significant moderator for the direct effects of attachment anxiety on …

Migration Information Gathering by Mexican-origin Immigrants in the Pre-migration Phase (open access)

Migration Information Gathering by Mexican-origin Immigrants in the Pre-migration Phase

U.S. immigration procedures are complex and may elude the average individual seeking admission to the United States. Understanding this, the current study investigates how information resources are used by potential migrants to learn about the migratory process. Using a mixed-methods approach, I interviewed 30 Mexican immigrants with unauthorized immigration experience about the process of gathering migration information in the pre-migration phase. Qualitative data were coded using seven themes generated from the primary research questions, including: Information Resources, Resources Used During Migration, Motivation for Migration, Method of Migration, Lack of Information/Misinformation, Types of Help and Types of Information. Findings suggest that the factors motivating migrants to come to the U.S. are combined in complex ways and lack of information about legal alternatives to unauthorized migration is an important factor influencing method of migration. Also, while access to new information resources is increasing, these resources are not being tapped for migration information.

Exploring Teachers’ Constructivist Beliefs Using Talis 2013: Approaches to Training and Development (open access)

Exploring Teachers’ Constructivist Beliefs Using Talis 2013: Approaches to Training and Development

The changing landscape of demographics, technology, and diversity in the learning environment is challenging schools around the world to rethink their approaches to the implementation of high-quality teaching practices. Classroom practices are becoming more complex because educators have to ensure that their students are well-equipped with 21st century skills (e.g., Darling-Hammond, 2010; Dede, 2010; Griffin, McGaw, & Care, 2012). Educators, curriculum developers, and school administrators need to be more than experts in pedagogy. They are now required to keep up with current ideas, innovative instructional practices, and the results of a variety of educational reform efforts. Believing that teachers’ beliefs are the most important psychological construct with regard to instructional practices (Pajares, 1992) and that teachers’ beliefs are related to their choice of classroom practices and, ultimately, the students’ performance (Bybee, Taylor, Gardner, Van Scotter, Powell, Westbrook, & Landes, 2006; Staub & Stern, 2002), the author of this study utilizes the international data set of the Teaching and Learning International Study (TALIS) 2013 to examine the associations between teachers’ constructivist beliefs, their self-efficacy beliefs, professional activities, and the school principals’ instructional leadership as related to lower secondary school teachers and principals in South Korea, Finland, and Mexico. These three countries …

"Para qué recorder": Preserving the Legacy of María Grever through Selected Vocal Compositions for Study and Performance (open access)

"Para qué recorder": Preserving the Legacy of María Grever through Selected Vocal Compositions for Study and Performance

María Grever (1885-1951) overcame racism and gender bias during a pivotal era in American music history to become the first commercially successful Mexican female composer and more specifically, a pioneer of popular music during the first half of the 20th century. Though named the "Madonna of song," her legacy is largely overshadowed by other compositional giants of the era, such as the Gershwin brothers, Cole Porter, and Irving Berlin. Grever's music is sophisticated, heartfelt, and worthy of attention. Her colorful, genuine music adds distinctiveness and variety to recital programs. Grever's songs offer a high level of musical integrity and socio-cultural value. Incorporating her compositions into a singer's vocal repertoire is an excellent way to broaden the scope of styles and languages while maintaining the highest standards of musical study. The following document considers the importance of performing and studying Grever's music by analyzing nine songs representing three compositional periods. I evaluated the songs considering pedagogical benefit, performance value, and significance to her overall oeuvre.

On the Fence (open access)

On the Fence

Living the vast majority of my life in an area that celebrates diversity but thrives because of illegal cross-border activities (undocumented workers, drug imports) at times the distance between the United States and Mexico is in fact as thin as the width of a fence. Though it is typical for a filmmaker to hope to present a unique take on a subject, given how I have seen the topics of immigration and the perspective of the purpose of homeland security portray, I am confident that there is an opportunity to show these issues in a more personal, less aggressive light with the use of first person accounts instead of a dependence on the most violent aspects of these topics. The main subject will give character to this agency by blurring the lines of his life as an agent and as a citizen.

Analysis of Micro Enterprise Clusters in Developing Countries:  A Case Study of Toluca, Mexico. (open access)

Analysis of Micro Enterprise Clusters in Developing Countries: A Case Study of Toluca, Mexico.

Businesses cluster to achieve agglomeration benefits. However, research in developing countries suggests that the economic environment limits small business’ propensity to benefit from agglomerations. The study examines the location, networking patterns, formal structures and owner characteristics of 1256 micro businesses from ten industries and thirteen sample areas in Toluca, Mexico. First, the thesis analyses whether clustering has a positive impact on the success rates of the surveyed enterprises, e.g. higher sales per employee. On an industry scale only Retail benefits from agglomerations economies. However, results of the neighborhood data show that specific areas benefit from urbanization economies. Overall, the study finds that businesses located within agglomerations, have higher levels of formalization, networking and professional training, hence constituting a more sophisticated base for economic development. Conclusions can be drawn for development policies and programs, arguing for a more differentiated approach of small business development depending on business location and cluster characteristics.

A Selective Lineage of Mexican Bassoonists (open access)

A Selective Lineage of Mexican Bassoonists

Spanish settlers brought the precursor to the bassoon, el bajón, to Mexico in the late sixteenth century. Documentation of the bassoon was intermittently from the sixteenth century on, the current playing traditions were not established until the second half of the twentieth century. Bassoon education in Mexico flourished in the 1970's because several bassoonists became expatriates, and chose to live and work in Mexico for the entirety of their careers. Two major pedagogues, Lazar Stoychev and Jerzy Lemiszka paved the way for the current Mexican bassoon community. This dissertation presents a selective lineage of bassoonists who have held positions in major Mexican orchestras and universities since the mid-twentieth century. The purpose of this study is to recognize the contributions these players and teachers have given to the bassoon world. In recent years, Mexican bassoonists have commissioned hundreds of works for the bassoon and this significant achievement has placed the Mexican bassoon community in an upward trajectory. To place these players in proper historical context, a brief history of classical music institutions in Mexico since the sixteenth century is given. This dissertation documents the history and pedagogy of recent bassoonists in Mexico via a cohesive family tree.

Drug-Related Violence and Party Behavior: The Case of Candidate Selection in Mexico (open access)

Drug-Related Violence and Party Behavior: The Case of Candidate Selection in Mexico

This dissertation examines how parties respond and adapt their behavior to political violence. Building a theoretical argument about strategic party behavior and party capture, I address the following questions: How do parties select and recruit their candidates in regions with high levels of violence and the pervasive presence of VNAs? Do parties respond to violence by selecting certain types of candidates who are more capable of fighting these organizations? Do parties react differently at different levels of government? And finally, how do VNSAs capture political selection across at different levels of government? I argue that in regions where there is high "uncertainty," candidate selection becomes highly important for both party leaders and DTOs. Second, I argue that as violence increases and the number of DTOs also, criminal organizations, as risk-averse actors, will capture candidate selection. I posit that as violence increases, there is a greater likelihood that candidates will have criminal connections. To test my theory, I use the case of Mexico. Violence in Mexico and the presence of criminal organizations across the country has experienced a great deal of variation since the 1990s. In Chapter 2, I find that violence affects the gubernatorial candidate selection of the PRI, PAN …

Joaquín de Arredondo in Texas and Northeastern New Spain, 1811-1821 (open access)

Joaquín de Arredondo in Texas and Northeastern New Spain, 1811-1821

Joaquín de Arredondo was the most powerful and influential person in northeastern New Spain from 1811 to 1821. His rise to prominence began in 1811 when the Spanish military officer and a small royalist army suppressed Miguel Hidalgo’s revolution in the province of Nuevo Santander. This prompted the Spanish government to promote Arredondo to Commandant General of the Eastern Internal Provinces, making him the foremost civil and military authority in northeastern New Spain. Arredondo’s tenure as commandant general proved difficult, as he had to deal with insurgents, invaders from the United States, hostile Indians, pirates, and smugglers. Because warfare in Europe siphoned much needed military and financial support, and disagreements with New Spain’s leadership resulted in reductions of the commandant general’s authority, Arredondo confronted these threats with little assistance from the Spanish government. In spite of these obstacles, he maintained royalist control of New Spain from 1811 to 1821, and, in doing so, changed the course of Texas, Mexican, and United States history. In 1813, he defeated insurgents and American invaders at the Battle of Medina, and from 1817 to 1820, his forces stopped Xavier Mina’s attempt to bring independence to New Spain, prevented French exiles from establishing a colony …

Bodies of Evidence: A Qualitative Analysis of the Lived Experiences of Female Central American and Mexican Asylum Seekers in Dallas (open access)

Bodies of Evidence: A Qualitative Analysis of the Lived Experiences of Female Central American and Mexican Asylum Seekers in Dallas

This work addresses the experiences of female asylum seekers from Central and Mexico currently living in Dallas, TX. The main purpose is to analyze how these women engage in the gendered processes of both migrating to and accessing legal resources and protection within the United States. As the women move through male-dominated spaces in their home country, the borderlands, and the asylum court they must challenge the patriarchal institutions that attempt to silence their narratives and criminalize their bodies. Their physical wounds become evidence in the courtroom, while outside of the courtroom their movements are monitored and tracked through multiple mechanisms of state control: ankle monitors, detention centers, ICE check-ins. They face intersectional discrimination as they are targeted as both women and immigrants. However, these female asylum seekers are not victims. They constantly display agency as they represent themselves in court, find solace in their faith, and form community with each other.

Embracing Internationalism: An Examination of Mario Lavista with an Analysis of Cinco Danzas Breves (open access)

Embracing Internationalism: An Examination of Mario Lavista with an Analysis of Cinco Danzas Breves

Mario Lavista (b.1943) is widely acknowledged as one of Mexico's foremost living composers. Having acquired his music education in his native Mexico and in Europe alike, he is similar to numerous other Latin composers who were building a career in the latter half of the twentieth century. During this time, composers were relying on international aspects of avant-garde techniques, and using nationalistic Latin rhythms and melodies less. Lavista embraced internationalism, and aimed to compose works devoid of identifiable elements of nationalism. This document argues that the absence of nationalistic elements in Lavista's music has affected his notoriety outside of Mexico. The role of nationalism is assessed through a brief examination of influential Mexican composers and educators prior to 1950, followed by a discussion of education and composition in the latter half of the twentieth century. These aspects are investigated with regard to Lavista's education and resulting compositional style. A theoretical analysis of Cinco Danzas Breves para quinteto de alientos (1994) serves as a representative example of Lavista's compositional style and influence. This document aims to highlight and increase exposure of Mexican composers outside of Latin America who do not compose nationalistic music.

Effects of Deepwater Horizon Crude Oil on Visual Function in Teleost Fishes (open access)

Effects of Deepwater Horizon Crude Oil on Visual Function in Teleost Fishes

The Deepwater Horizon oil spill released millions of barrels of oil into the Gulf of Mexico, impacting economically and ecologically important fishes. Polycyclic aromatic hydrocarbons (PAHs) present in the oil have been shown to cause developmental impairments in early life stage fishes, such as morphological and behavioral changes related to eye formation and visual processing following PAH exposure. Prior research reported reduced eye growth in open water, pelagic species, as well as reduced photoreceptor-specific transcription factors associated with eye development following exposure to crude oil. Though changes in transcriptomic-level pathways associated with vision and visual processing have been reported, it has yet to be determined how these changes relate to physiological or behavioral-level effects in fish. Therefore, the present studies evaluated the effect of weathered crude oil on eye development and visual function in mahi-mahi, red drum, sheepshead minnow, and zebrafish larvae. Fish were assessed through several visually-mediated behavioral assays, analyzed histologically and immunohistologically, along with subsequent transcriptomic analyses and associated gene expression changes. Larvae exposed to crude oil experienced significantly reduced abilities to exhibit optomotor or optokinetic responses relative to controls, with associated reductions in retinal development. Furthermore, genes associated with eye development and phototransduction were downregulated, with subsequent …
