The Tigua Indians Of Ysleta Del Sur: A Borderlands Community, Scott C. Comar

Open Access Theses & Dissertations

This Dissertation offers a broad community history of the Tigua Indians of Ysleta del Sur Pueblo from colonial contact to their federal recognition in 1987. Considering Tigua history in a Borderlands context, it explores the interaction between community and identity. Here I argue that the Tiguas persisted through Spanish, Mexican, and American colonization because various identity markers involving place, interaction, and shared culture enhanced their community identity as an Indigenous people. This Dissertation also examines how social upheaval, migrations, and land dispossession impacted the Tiguas in various contexts, as well as some of the ways in which they adapted to …

Influence Of Stress On Substance Use: Age-Associated Variability In Molecular And Behavioral Outcomes, Christina Elizabeth D'Arcy

Open Access Theses & Dissertations

Stress introduces a number of neurological and neurohormonal changes in response to a number of stimuli, and can influence our relationship to rewarding experiences. As such, it holds the potential of promoting vulnerability to addiction to substances such as methamphetamine. While methamphetamine use and abuse has been steadily declining, the fact remains that it and closely related drugs are used in the treatment of conditions such as narcolepsy, weight loss, and attention deficit disorder. In an effort to develop better patient assessment metrics to aid the physician in deciding a course of treatment, we ask the following questions: Do chronic …

Deviant Politics: Hip Hop As A Form Of Resistance Against Hyper Criminalization And Structural Violence

Re-Examining Resistance: Fan-Produced Queer Readings And Teen Wolf, Joshua J. Espinoza

Open Access Theses & Dissertations

MTV's popular television series, Teen Wolf (2011), has amassed a large online following of fans that create their own queer narratives through fan-fiction, subverting the show's hegemonic heteronormativity. Through a textual thematic analysis of Teen Wolf, this case study illustrates how online fandoms can subvert hegemony through queer readings of literary characters, resisting the dominant heteronormativity on network television. This article argues that rearticulating the showâ??s narratives into queer readings functions as a form of LGBT resistance, effectively counteracting the heteronormativity and hegemony portrayed on screen. This study examines how Teen Wolf approaches queer content, including homoeroticism and LGBT themes …

The Effects Of Stock Distributions On Returns, Volatility, And Price, Jason Heavilin

Open Access Theses & Dissertations

This Dissertation investigates three issues regarding the effects of stock distributions on returns, volatility, and prices in an attempt to answer the questions why firms execute stock distributions and why the market appears to favor them. These questions have occupied academicians for at least 40 years (i.e., Fama et al (1969), Ohlson and Penman (1985), Rankine and Stice (1997), Angel (1997), and Crawford et al (2005) among many others).

Chapter 1 studies the notion that the stock market reacts more positive to stock dividends than to stock splits (Rankine and Stice, 1997). However, I find that the stock market does …

Multi-Expert Multi-Criteria Decision Making, Joel Henderson

Open Access Theses & Dissertations

Expert analysis and decisions are highly valued assets in a wide variety of fields, from social services to grant funding committees. However, the use of experts can be prohibitive due to either lack of availability or cost. As such, it is desirable to be able to replicate such decisions. However, there are many obstacles that impede an accurate simulation of expert decisions. For example, despite looking at the same information, two experts may disagree on the decisions. In addition, a single expert may make inconsistent decisions across similar scenarios.

In this work, we focus on multi-criteria decision making and in …

Immigration And Family Violence At The Household Level Of Analysis: Examining The Effects Of Immigrant Culture And Neighborhood Structure, Jorge Luis Hernandez

Open Access Theses & Dissertations

This study concerns the relationship between immigration and family violence at the household level of analysis. Previous studies have suggested that immigrant status - particularly first generation immigrant status - is not associated with crime. However, the same cannot be said about their descendants the second and third generations; as they are not as insulated from crime as their forefathers. This study measures the following variables which are relevant to the immigration and family violence relationship; immigrant generational status, acculturation levels, patriarchy, family oriented values, collective efficacy, surveillance, and measures of informal social control. This study finds that there is …

Market Reactions To Businesses' Actions Towards People With Disabilities: Making The Business Case In The International Context, Claudia Araceli Hernández González

Open Access Theses & Dissertations

From the business point of view, people with disabilities still suffer discrimination in employment and lack of accessibility as customers. Opposing, as recipients of philanthropic efforts many individuals and firms donate resources to improve the life of people with disabilities. These actions demonstrate how the majority of the population is still fixed in a medical model of disability by trying to repair the person to conform to the social norm, instead of accepting that many disabilities do not undermine other abilities. However, there is little evidence of how these actions impact the financial performance of the organization. This study attempts …

Beneath The Kiss: Unearthing The Ideological Underpinnings Of Kay Jewelers Advertisements, Chelsea Nedlyn Hill

Open Access Theses & Dissertations

ABSTRACT

Advertising is a frequently used influential and persuasive means of communication, such as Kay Jewelers, a corporation whose advertising methods have been superficially appealing to a female audience. However, this study sought to investigate the ideological underpinnings associated with Kay Jewelers advertisements, employing an ideological criticism to argue through feminist theory that Kay Jewelers utilizes key elements of heteronormative love as a means to persuade and influence men to purchase their jewelry products. Through this underpinning of heteronormative romance, Kay Jewelers emphasizes the notion that an artifact, like a piece of jewelry, is necessary in order to properly express …

High Temperature Helical Tubular Receiver For Concentrating Solar Power System, Nazmul Hossain

Open Access Theses & Dissertations

In the field of conventional cleaner power generation technology, concentrating solar power systems have introduced remarkable opportunity. In a solar power tower, solar energy concentrated by the heliostats at a single point produces very high temperature. Falling solid particles or heat transfer fluid passing through that high temperature region absorbs heat to generate electricity. Increasing the residence time will result in more heat gain and increase efficiency. A novel design of solar receiver for both fluid and solid particle is approached in this paper which can increase residence time resulting in higher temperature gain in one cycle compared to conventional …

Sociocultural Influences On Perceived Risk In Latinos At Risk Of Developing Type 2 Diabetes, Allyson S. Hughes

Open Access Theses & Dissertations

Previous studies have shown that perceived risk is a predictor of positive health behaviors to avert preventative chronic conditions. As a major factor in the Health Belief Model, high levels of perceived risk may operate as a "perceived susceptibility" to disease and may function as a "perceived threat" that triggers action towards preventing the onset of disease (Champion & Skinner, 2008). Following an Ecodevelopmental Model approach in an effort to prevent prediabetes and type 2 diabetes (Castro, Shaibi & Boehm-Smith, 2009) includes understanding the potential protective effects of certain cultural factors (including sources of social support that can promote healthy …

Design Of A High Intensity Turbulent Combustion System, Mohammad Arif Hossain

Open Access Theses & Dissertations

In order to design next generation gas turbine combustor and rocket engines, a systematic study of flame structure at high intensity turbulent flow is necessary. The fundamental study of turbulent premixed combustion has been a major research concern for decades. The work is focused on the design and development of a high intensity turbulent combustion system which can be operated at compressible (0.3 < M < 0.5), preheated (T0=500K) and premixed conditions in order to investigate the 'Thickened Flame' regime. An air-methane mixture has been used as the fuel for this study. An optically accessible backward-facing step stabilized combustor has been designed for a maximum operating pressure of 6 bar. A grid has been introduced with different blockage ratios (BR = 54%, 61% & 67%) in order to generate turbulence inside the combustor for the experiment. Optical access is provided via quartz windows on three sides of the combustion chamber. Finite Element Analysis (FEA) is done in order to verify the structural integrity of the combustor at rated conditions. In order to increase the inlet temperature of the air, a heating section was designed to use commercially available in-line heaters. Separate cooling subsystems have been designed for chamber cooling and exhaust cooling. The LabVIEW software interface has been selected as the control mechanism for the experimental setup. A 10 kHz Time Resolved Particle Image Velocimetry (TR-PIV) system and a 3 kHz Planer Laser Induced Fluorescence (PLIF) system have been integrated with the system in order to diagnose the flow field and the flame respectively. The primary understanding of the flow field inside the combustor was achieved through the use of Detached Eddy Simulation (DES) by using commercially available software package ANSYS FLUENT. Preliminary validation is done by 10 kHz TR-PIV technique. Both qualitative and quantitative analysis have been done for CFD and experiment. Major flow parameters such as average velocity, fluctuation of velocity, kinetic energy, and turbulent intensity have been calculated for two distinct Reynolds number (Re = 815 & 3500). PIV results are compared with CFD results which show significant agreement with each other.

Rents, Loyalty, And The Economy: How An Unstable Economy Plays A Role In The Occurrence Of Coups D'État, Alexandra Elizabeth Infanzon

Open Access Theses & Dissertations

This Thesis examines why coups d'état still occur, regardless of institution type, in some states but not others. Building off Wintrobe's and Hiroi and Omori's observations, an elite theory is presented that attributes the success of avoiding coups lies in both the stability of economic growth and a system of internal incentives that create a direct link between the government and the people. Without either present, the elite in government are not constrained from engaging in undemocratic behavior and usurping power, ultimately resulting in coups. Using a zero-inflated negative binomial logistic regression, indicators of economic stability and internal loyalty systems …
