Understanding Local Vulnerability In The Rio Grande Valley, Yajaira I. Ayala

Theses and Dissertations

Located on the Texas-Mexico border, the Rio Grande Valley is characterized by its geographical susceptibility to hurricanes and floods. With high poverty rates and a majority Hispanic and Latino population, “the Valley” faces multiple challenges; many residents of the area live below federal poverty rates, have low educational attainment, speak little to no English, or are migrants with low social capital. These prevailing conditions have established the Rio Grande Valley as a highly vulnerable region compared to other areas in the United States. This paper aims to bring awareness of these prevalent inequalities existing within the area, and to participate …

The Interplay Between Change And Project Management For Business Results, Taiwo O.O. Abraham

Theses and Dissertations

The present study investigates the potential interplay between change management and project management. The research aims to determine the causal effect between the two concepts. Data is collected from a focus group comprised of various managers. The study concludes that managers readily apply the concepts of both change management and PM when making decisions.

Three Essays On Venture Capital Backed Firms And Peer To Peer Lending, Abdelhamid Riani

Theses and Dissertations

This dissertation includes three separate essays related to venture capital backed firms and peer to peer lending. The first essay, presented in Chapter II, studies underpricing and buy and hold abnormal returns in venture capital backed firms.

In this chapter, I conduct an analysis of underpricing and buy-and-hold abnormal returns in venture capitals' portfolio of firms using a sample of 991 venture backed IPOs between 1985 and 2018. I show that the more experienced the venture capital is, the larger the underpricing and the lower the buy-and-hold returns of the whole portfolio. Venture capital investors underprice significantly their portfolio of …

Essays In Corporate Finance, Bina Sharma

Theses and Dissertations

In this dissertation, I explore the effects of exogenous shocks on firms' and managers' behaviors. The first essay examines the effect of shareholder-initiated litigation risk on opportunistic insider trading by exploiting US states' staggered adoption of Universal Demand (UD) laws, which weakened shareholders' ability to file derivative lawsuits against corporate insiders. I find that UD laws lead to significantly more profitable insider trades, specifically insider sales. After the adoption of UD laws, insider sales on average avoid an additional loss of about 2 percent ($24,000) per month in buy-and-hold abnormal returns. The benefit of UD laws is greater for insiders …

Music, Dance, And Tourism In Los Cabos, Mexico, Melanie E. Davis

Theses and Dissertations

For a thriving music and dance scene to flourish in tourist destinations, certain factors for performers must be present including economic stability, a baseline level of patronage, resilience to seasonal tourist fluctuations, and adaptation to demographic changes over time. In the Los Cabos arts community, local aesthetics are transformed and embodied by work of performers whose activities are multicultural and multilingual. Over the past fifty years, Los Cabos was transformed from a sleepy fishing village into a major international destination. The island-inspired arts scene includes live performances featuring cultural representations from other lands besides Mexico. Grounded in the humanities, I …

Theses and Dissertations

The history of the Apostolic Assembly of the Faith in Christ Jesus, Inc. of the Rio Grande Valley is one that is unknown by many people. As a matter of fact, even many members of this movement do not know their own history, because it is not something that they are taught to appreciate. The purpose of this thesis is to inform, not only the members of the Apostolic Assembly of their history, but to teach non-members and historians interested in the Rio Grande Valley region the intertwined history of Apostolicos with that of the region and part of the …

Retratos De Las Criollas: Fashioning An Identity In Eighteenth-Century Bourbon New Spain And Peru, Daniel F. Ymbong

Theses and Dissertations

This master's thesis will examine the iconographies of elite Creole women in Bourbon eighteenth-century New Spain and Peru. This paper is a comparative study of the colonial regal portraits of elite Creole women with emphasis on preferences in: dress, hair, and accessories.

Much of the pictorial format is informed by European styles and decorum, that is the Spanish and Italian Renaissance in materiality. The prevailing silhouettes dictated by the French Bourbons are adapted, but strategically morphed an identity for the colonial elites, as there were different preferences for colors, accessories, and hair.

Investigating Limitations To Nitrogen Fixation By Leguminous Cover Crops In South Texas, Stephanie L. Kasper

Theses and Dissertations

Many farms use leguminous cover crops as a nutrient management strategy to reduce their need for nitrogen fertilizer. Biological nitrogen fixation (BNF) depends on a symbiotic relationship between legumes and nitrogen-fixing rhizobia. Under certain conditions despite inoculation with appropriate rhizobial strains, this symbiosis fails to form. Such failure was observed in a 14-acre winter cover crop trial in the Rio Grande Valley of Texas when three legume species (forage pea, crimson clover, and hairy vetch) produced no signs of nodulation and nitrogen fixation. This study examined nitrogen, phosphorus, moisture, micronutrients and biotic interference as potential causes for the failure and …

Art Of Katharsis: A Study Of Creating Abstract Expressionist Art In The Quest For Emotional Release And Healing, Maria Fatima Lai

Theses and Dissertations

This thesis paper discusses the art seen in the exhibition, Katharsis, is a body of work inspired in the quest to validate suppressed emotions pulling from personal experiences of grief and abandonment. The methodology behind the work explores the artistic process that enables the transformation of pain and grief. The research is guided by understanding the artist’s process through therapeutic methods found in abstract expressionism. Art produced in pain, allowed a process of healing and honest forgiveness. The vicious cycle of feeling trapped in the idea of letting go when you have not allowed yourself to understand, threatens the …

Does Machismo Culture Influence Latina/O Attitudes On Mental Health?, Amanda R. Mercado

Theses and Dissertations

This study represents an attempt to contribute to the identified gap in knowledge towards the effects of machismo on both Latina women and Latino men and how it effects their attitudes towards mental health. The idea that previous research on machismo has been so one-sided, but has revealed that psychological distresses were present and ignored, leaves room for my research to explore how Latina women are affected because they are just as susceptible to psychological distresses as men. By using a research based framework to explain the effects of machismo on both Latina women and Latino men, my study will …

Healing And Resistance Through Humor: A Literary And Cultural Analysis Of Chicana And Latina Cultural Production, Victoria E. Valdez

Theses and Dissertations

This thesis analyzes elements of humor used by Chicana cultural producers (poets, performance artists, stand up comediennes) to subvert negative stereotypes of Chicanas. Chicana humorists have challenged harmful images of Mexican American women through poetry, prose, performances, and stand-up comedy. While Américo Paredes created a scholarly foundation for the study of Chicano humor, it is evident that Chicanos and members of dominant society mock Chicanas with their brand of humor. I argue writers like Michele Serros and Lorna Dee Cervantes resist dichotomous Chicana imagery and instead create and add to Chicana representation with humor. This thesis examines performance artist Maria …

Local Disaster Planning And Preparedness Coordination In The Rio Grande Valley, Cristina L. Madrid

Theses and Dissertations

Hurricanes and flooding events yield complex social and environmental consequences to coastal communities. Disaster preparedness and recovery is a multidisciplinary and multi-jurisdictional effort that requires coordination and planning across many actors.

Existing research recognizes the link between social capital and a community’s ability to respond to and ‘bounce back’ to normalcy after such hazardous events. However, few studies have examined the institutional dimension of social capital among communities noted for high levels of poverty situated in disaster-prone areas along the U.S. Mexico border. We aim to fill this gap by using survey data collected from emergency management practitioners in the …

Vocational Rehabilitation Counselors' Experiences, Perceptions, And Readiness Related To Self-Employment Of People With Disabilities, Deborah Ashley

Theses and Dissertations

The purpose of this dissertation study was to explore the experiences, perceptions, and readiness (EPR) of vocational rehabilitation counselors (VRCs) supporting people with disabilities (PWD) in self-employment. While PWD are twice as likely to be self-employed than the general population, self-employment case closure rates within vocational rehabilitation remain historically low around 2%.

Descriptive, inferential, and correlational statistical analysis were used to investigate the EPR of 205 Certified Rehabilitation Counselors across the nation via an online survey, the Vocational Rehabilitation Counselor Self-Employment Process Survey (VRC-SEPS). The VRC-SEPS consists of demographic items, two Likert-type scales examining experiences and readiness, and a set …

Hispanic Culture And Machismo: How Hispanics Interpret Transgender And Gender Non-Conforming Identities, Karen R. Rodriguez

Theses and Dissertations

This study examines dynamics linked to normative gender expectations and gender identities within Hispanic culture. Little is known in this regard concerning how Hispanics perceive and interpret transgender and gender non-conforming identities. The analysis provides qualitative assessment using 35 in-depth face-to-face interviews and examines the following research questions: 1) how do life experiences such as marriage, parenthood, and work force participation among Hispanics shape their formation of gender expectations? 2) Among Hispanics, how do class, race/ethnicity, and education shape the construction of gender ideologies.

The present study, in turn adds to the literature by examining gender norm constructs among Mexican-origin …

Essays On Market Linkages In Nafta And Latin American Countries: Studies Of Cointegration And Contagion, John K. Tarwater

Theses and Dissertations

The globalization of securities in recent years has led to an increase in market linkages. These linkages are strong among countries that have entered into bilateral and multilateral trade agreements. I investigate the linkages of stock markets in NAFTA countries by exploring their cointegrating relationship, and I explore market linkages in Latin America by showing evidence of financial contagion between Brazil and her Latin American neighbors.

In the first essay, I employ a vector error correction model to examine the linkages between price stock indexes of NAFTA countries that have been segregated into tiers based on market capitalization. In each …

A Contingency Approach For Supply Chain Preparedness To Pursue Circular Economy Business Models, Santosh Nandi

Theses and Dissertations

A growing stream in circular economy (CE) research is about circular economy business models (CEBM). It suggests how firms could learn to adopt unique material and product designs, newer business models, value chain networks and potential enablers that satisfies CE ideologies about economic, environment, and society. However, the understanding about how firms could integrate CEBM practices at internal, supply chain, and external levels is limited. Given the rising complexities in supply chains, the goal of this dissertation is to: (a) understand the landscape of CE concepts within the supply chain management context, and consequently (b) comprehend how firms’ preparedness about …

Generational Status And Views On Nonconforming Gender Expression Among Individuals Of Mexican Origin, Bianca C. Lopez

Theses and Dissertations

Despite recent change of perspectives and an increase of acceptance of gender nonconformity, the concept of gender still remains a controversial topic. Gender continues to be a developing idea and maintains an influential role in many cultural contexts. Examining facets of gender in various settings can perhaps enlighten our comprehension of such and a further understanding of those who express gender nontraditionally. This study examines the concept of gender in a less traditional stance, exploring views of non-conforming gender expression among generations of Mexican Americans and individuals of Mexican origin. Through analysis of survey data on views of gender nonconformity …

The Witch, The Blonde, And The Cultural "Other": Applying Cluster Criticism To Grimm And Disney Princess Stories, Valerie F. Garza

Theses and Dissertations

The Brothers Grimm and the Walt Disney Company have produced popular fairy tales for large audiences. In this work, cluster criticism—a rhetorical criticism that involves identifying key terms and charting word clusters around those terms—is applied to four Grimm fairy tales and four Disney princess films. This study aims to reveal the worldview of the rhetors and explore how values present in Grimm tales manifest in contemporary Disney films. Disney princess films in this study have been categorized as “White/European” and “Non-White/Cultural ‘Other.’” Because film is a form of non-discursive rhetoric, an adaptation of cluster criticism designed for film was …

Theses and Dissertations

This thesis analyzes the conditions the mentally ill and mentally disabled population in the Rio Grande Valley faced during the era of the asylum in the United States, from 1860 until 1962. The treatment options for the citizens of the Rio Grande Valley are compared with the treatment of the mentally ill in the nation as a whole, as well as in the state of Texas. The Rio Grande Valley has been geographically distant from large population centers, and the state of Texas neglected to place any state-funded health care centers in the region until the 1960's. The Rio Grande …

Theses and Dissertations

This dissertation consists of four chapters, focusing on American Depositary Receipts (ADRs) and how they are affected by new measures of investor sentiment, new proxies of investor attention, and financial bubble detection. ADRs are negotiable certificates of ownership in foreign companies that are traded in the U.S. financial markets.

In Chapter I, I make a brief introduction of ADRs. The types of programs there are, the market capitalization and volume in general and to some specific countries.

In Chapter II, I show that negative investor sentiment measures, derived from internet aggregate search indices, have a contemporaneous negative effect on ADR …

Three Essays On Economic And Financial Development In Latin America: Evidence From The 2000s Commodity Boom, Andre Coelho Vianna

Theses and Dissertations

The dynamic forces of commodity prices have become a subject of large interest due to the uprise of a commodity supercycle in the beginning of the 21st century. The main purpose of this dissertation is to assess the role of commodity shocks and international trade in Latin American financial and economic development in the last two decades. The first essay examines how commodity market structural shocks explain the variations in commodity prices. Structural Vector Autoregression (SVAR) results from 1997 to 2015 show that aggregate demand shocks are more evident during the recent commodity boom period and are robust to different …

Theses and Dissertations

This study is an autoethnography which will identify major ethnographic influences that I, as a female Mexican American educational leader, feel have been significant in the course of my career in education. The study will focus on culture, family and community as factors which developed and engendered characteristics, behaviors and experiences that contributed to my development as an educator. These will be relayed through narratives, memoirs, organic artifacts and documents, lived experiences, pláticas, and other forms of text presented here as story, an acceptable autoethnographic method of data collection. I place myself in the center of these narratives in autoethnographic …

Essays On Financial Markets And Investments, Shahil Sharma

Theses and Dissertations

Essay I examine regime-switching in the response of U.S. stock price to oil price shocks. We find statistically significant, time-varying, and dynamic state dependent response that resembles to high and low response regimes. Furthermore, we examine whether the timing of the regime shifts are consistent with three (direction, magnitude, and business cycle) manifestations of asymmetry by modeling the transition probabilities governing the switching process as functions of state variables. We observe strong and statistically significant support that stock price responds more aggressively to oil specific shocks during recessions than during expansions, while findings suggest weaker evidence of asymmetry pertaining to …

International Migration In Santa María Huatulco, Oaxaca [Migración Internacional En Santa María Huatulco, Oaxaca], Yasmin Angelie Cordero

Migration into rural areas has been of increasing interest in the last decades of research. Mexico has implemented development initiatives to reduce emigration and strengthen locally depressed communities resulting in immigration to the target areas. Santa María Huatulco is one of the areas of focus where the Mexican government created tourism development projects subsequently attracting internationals to migrate. This study focuses on international migrants who have chosen to relocate to the area of Huatulco, currently under development by the Mexican government. This was one of Mexico’s poorer regions and has seen the slowest amount of growth since the development projects …

Chapter III summarizes the findings and provides concluding remarks regarding the benefits and disadvantages in adopting a floating exchange rate …

Teaching And Living In La Frontera: Teacher Perceptions Of Mexican Immigrant Students' Lived Experiences With Border Violence, Edith Trevino

Theses and Dissertations

This research is grounded in the truth of my own lived experience with border violence in La Frontera. Gloria Anzaldua (1987), describes the U.S. Mexico border (La Frontera) as an “open wound where the Third World grates against the First World and bleeds”(p. 3). Border violence in La Frontera is discussed in this research through four lenses which create a nexus of intertwined connections within curriculum and education. I use the lens of a grieving displaced daughter, a desperate mother trying to find support for her traumatized child in a failing educational system, a teacher who tries to honor her …
