A Melting Pot Of Voices: Public Discourse And The Latino Immigrant Experience In The United States, Elizabeth Katherine Vammen

Graduate Theses and Dissertations

This study examines the discourses surrounding the immigrant experience in the United States to reconcile first-hand accounts of Latino immigrant experiences with the discourse prevailing in broader domains such as immigration law, public forums, non-fiction essays, and the news media. In order to break down barriers that prevent productive discussions, this analysis identifies stifling language guised under what Antonio Gramsci defines common sense rather than good sense. At the same time this study aims to deconstruct stifling language, it uses first-hand accounts from Latino immigrants to provide insight as to where the American public is not listening. By analyzing common …

Salman Rushdie In The Postmodern Current: New Venues, New Values, Aya Akkawi

Graduate Theses and Dissertations

The aim of this study is to prove that Rushdie's recent novels are not postcolonial in the sense that they abandon the colonial/colonized binary, the embrace of hybridity, and the theme of undermining the coercion and domination of the colonial country assumed in postcolonial discourse. Instead, his recent fiction is labeled postmodern because it is filled with exuberant postmodern techniques such as historiographic metafiction, the hegemony of mode of productions, the postmodern fragmented self, and suspicions of grand narrative. Furthermore, I will argue that there is an association between Rushdie's postmodern narrative technique (his mixing of history and fantasy) and …

Essays On Smallholder Farmers In Jamaica: Context-Specific Evidence For Food Security Policymaking, Deborah Evadne Brown

This formed the basis for a farmer typology that provides a portrait of the participants, and was used to inform findings in subsequent essays in this dissertation. The theory of planned behavior provided the conceptual grounding and …

The Quality Of Presence: An Essential Component Of Therapeutic Work, Melissa R. Haley

Graduate Theses and Dissertations

The concept of therapeutic presence has only recently been addressed in the literature. However the literature regarding this topic indicates that therapeutic presence is an important aspect of effective therapy (Boudette, 2011; Bradford, 2007; Greason & Cashwell, 2009; Hall-Renn, 2006; Nanda, 2009). As much of the literature is comprised of conceptual pieces, empirical data needs to be expanded on regarding therapeutic presence. One of the areas that is not addressed in the literature is how practicing counselors perceive or utilize presence The objective of this qualitative study was to gather information from a sample of expert counseling practitioners concerning therapeutic …

The Influence Of Literacy On The Lives Of Twentieth Century Southern Female Minority Figures, Laura Leighann Dicks

Graduate Theses and Dissertations

The American South has long been a region associated with myth and fantasy; in popular culture especially, the region is consistently tied to skewed notions of the antebellum South that include images of large plantation homes, women in hoop skirts, and magnolia trees that manifest in television and film representations such as Gone With the Wind (1939). Juxtaposed with these idealized, mythic images is the hillbilly trope, reinforced by radio shows such as Lum and Abner, and films such as Scatterbrain (1940). Out of this idea comes the southern illiteracy stereotype, which suggests that southerners are collectively unconcerned with education …

Means-Tested Vouchers: Impacts On Public School Performance & Racial Stratification, Anna Jacob

Graduate Theses and Dissertations

This dissertation examines the systemic effects of private school choice in the context of two statewide, means-tested school voucher programs-- the Indiana Choice Scholarship Program (ICSP) and the Louisiana Scholarship Program (LSP). Specifically, I examine public school responses to private school competition from the ICSP and the LSP and the direct impacts of the LSP on racial stratification in public and private schools. In Louisiana, I show that the lowest-graded public schools had a modest, statistically significant, positive response to the injection of competition, with impacts ranging from .001 to .06 SD. In Indiana, the evidence is slightly weaker. In …

Assessing The Effectiveness Of Student Oriented Learning Outlines (Solos) In An Equine Classroom, Kathleen S. Jogan

Graduate Theses and Dissertations

Thirty-one students who were enrolled in 2012 were in the non-SOLO group (control), and 25 students who were enrolled in 2013 were the SOLO group (treatment). Three separate units were taught to the treatment and control groups with only one difference: the treatment group was given a SOLO one week in advance …

A Novel Cell Based Assay For Mmp Inhibitor Screening, Pantrika Krisanarungson

Graduate Theses and Dissertations

Up to date, a plethora of protein based materials are used as implants to stimulate tissue regeneration or fillers to alleviate tissue or organ impairment. This includes glottal insufficiency, urinary bladder incontinence and especially in cosmetic industrial to improve facial contour. Once in vivo, protein-based materials are decomposed by cell secreted matrix metalloproteinases (MMP) and lose their volume within months. By introducing MMP inhibitor (MMPI), the extent of material degradation over time may be reduced. In this dissertation, the development of cell-based assay capable of identifying MMPI candidates for protein-based implant lifetime prolongation is described. To visualize the degradation, DQ-gelatin, …

Optimum Design Of Spectral Efficient Green Wireless Communications, Gang Wang

Graduate Theses and Dissertations

This dissertation focuses on the optimum design of spectral efficient green wireless communications. Energy efficiency (EE), which is defined as the inverse of average energy required to successfully deliver one information bit from a source to its destination, and spectral efficiency (SE), which is defined as the average data rate per unit bandwidth, are two fundamental performance metrics of wireless communication systems. We study the optimum designs of a wide range of practical wireless communication systems that can either maximize EE, or SE, or achieve a balanced tradeoff between the two metrics. There are three objectives in this dissertation. First, …

Assessing Food Policy Options In Asia To Reduce Price Volatility Of Rice Market, Ranjitsinh Mane

Graduate Theses and Dissertations

Rice is a staple food in Asia and its prices at national and international levels are largely influenced by different policy actions of trading countries. The consequence of the 2008 food crisis was food riots and rationing of rice in many nations. The ASEAN Plus Three (APT) countries have adopted an institutional framework called ASEAN Plus Three Emergency Rice Reserves (APTERR) to address food security concerns of ASEAN countries that may arise due to climate change, supply chain disruptions or price speculation in the regional rice market. The RICEFLOW model is used to study the effectiveness of the strategic grain …

Ethnocultural Differences In Motivations For Sex, Arthur Robert Andrews Iii

Graduate Theses and Dissertations

Motivations for sex are numerous and varied (Browning, 2004; Meston & Buss, 2007). Using exploratory factor analytic methods, 21 theoretically distinct motivations have been proposed (Browning, 2004; Meston & Buss, 2007). A comprehensive number of motivations for sex has yet to be examined with confirmatory techniques. Theoretical work related to the treatment of sexual dysfunction has suggested that motivations focused on individual and partner pleasure would positively relate to sexual functioning (e.g., Leiblum & Rosen, 1992). Motivations for sex also appear to vary as a function of ethnocultural factors, as some motivations have only been uncovered utilizing qualitative methods with …

A Comparison And Evaluation Of Different Dynamic Characterization Approaches For Bridges, Juan Javier Torres Torres Goitia

Graduate Theses and Dissertations

The objective of this thesis was to compare different dynamic characterization approaches for full scale bridge structures to devise a rapid and reliable Structural Health Monitoring (SHM) program in the aftermath of a natural or manmade hazard. Present methods for structural condition evaluation of bridge structures rely heavily on on-site visual inspections of each structure by specially trained engineers and technicians. It has been proved in the literature that this current method is subjective, time consuming and manpower intensive, all of which are not suited for the critical conditions following a hazard event. This study focused on comparing three different …

Comparing Ferrous Chloride And Ferrous Sulfate As Secondary Coagulants At The Beaver Water District Drinking Water Treatment Plant, Jenny Doyle

Graduate Theses and Dissertations

In November 2012, the Beaver Water District (BWD) switched primary oxidants from free chlorine to chlorine dioxide (ClO2) to curb formation of trihalomethanes, a regulated group of organic disinfection byproducts (DBPs). Because ClO2 is reduced to chlorite (ClO2-), a regulated inorganic DBP, BWD incorporated ferrous salt into their coagulation regime to quench chlorite to chloride. In this study, two ferrous salts - ferrous chloride (FC) and ferrous sulfate (FS) - were compared as secondary coagulants in combination with alum, the primary coagulant. Ferrous salts were dosed stoichiometrically to reduce chlorite and alum was dosed at percentages (0-100%) relative to a …

Graduate Theses and Dissertations

This study investigates the role of intolerance of uncertainty in international students' conflict management in intracultural and intercultural settings. International students at a large U.S. university were surveyed and their responses were analyzed using quantitative methods. Analyses indicated that the higher the intolerance of uncertainty scores, the higher the use of dominating and avoiding strategies. The results in this study also revealed that when controlling for sex, the higher the individuals' intolerance of uncertainty score, the lower their preference for integrating-compromising strategy. Finally, there were limited differences between the ways international students handle conflict with conflict partners from their own …

Properties Of Multiferroic Bifeo3 From First Principles, Dovran Rahmedov

Graduate Theses and Dissertations

In this dissertation, a first-principle-based approach is developed to study magnetoelectric effect in multiferoic materials. Such approach has a significant predictive power and might serve as a guide to new experimental works. As we will discuss in the course of this work, it also gives an important insight to the underlying physics behind the experimentally observed phenomena.

We start by applying our method to investigate properties of a generic multiferroic material. We observe how magnetic susceptibility of such materials evolves with temperature and compare this evolution with the characteristic behavior of magnetic susceptibility for pure magnetic systems. Then we focus …

Campylobacter is the leading cause of foodborne illness worldwide and human illnesses are often associated with consumption of poultry or poultry products. Many strategies have been tried to eliminate Campylobacter from poultry with limited success. One of the strategies to reduce Campylobacter colonization in poultry is by use of probiotics. We conducted 2 separate studies to evaluate the efficacy of probiotics against Campylobacter in broiler chickens. For our first study, GRAS (Generally Regarded as Safe) bacteria were isolated from healthy chickens and tested their efficacy against Campylobacter in vitro. Twenty six isolates with in vitro anti-Campylobacter activity were …

Violations Of Protection Orders: Characteristics Of Offenders And Criminal Justice Responses, Kelly Eileen Henderson

Graduate Theses and Dissertations

Criminal justice research often finds gender-based differences with regard to both perpetration and responses to offending. These data indicate that, overall, women's crime rates are far below those of their male counterparts and that women commit less serious offenses. That is there are distinct patterns of offending across sex. In addition, justice responses tend to favor women, in that female offenders fare better than men particular in areas of arrest, prosecution, and sentencing. While previous research explores patterns of crime between male and female offenders, focusing primarily on drug or violent crimes such as homicide, there has been very little …

Power To The People? An Evaluation Of State-Level Environmental Justice Policies, Angela Michelle Hines

Graduate Theses and Dissertations

Communities of color in America lacking economical, educational, and political power have been largely invisible in the process of making major policy decisions. This is lack of access to decision-making venues has been viewed by many as the reason behind marginalized populations bearing the brunt of many societal burdens. The Environmental Justice Movement legitimized the claims of inadequate access to the decision-making process concerning environmental conditions in which African-Americans lived and worked. Through the use of disruptive actions reminiscent of those used throughout the Civil Rights Movement, the plight of communities plagued by the daily presence of hazardous waste gained …
