The Good, The Bad, And The Uncivil: An Analysis Of Uncivil Members Of Congress From The 45th To The 113th Congresses, Nathan Lea Holm

Graduate Research Theses & Dissertations

Incivility in Congress has often been attributed to partisan and ideological conflict, but there is a growing body of evidence that suggests incivility may hinge on factors concerning members’ personal attitudes as defined by their life experiences. To investigate this, background and experiential factors that may lead to incivility are tested, including variables such as family dynamics, religion, occupation, and education. All of these factors are tested on the basis that they could have formative influence on a legislator’s behavior and how they conduct themselves as a member of the US Congress. Seven members of Congress from the 45th to …

Cultural Models Of Democracy Among Burmese Residents In Chicago, Illinois, And Fort Wayne, Indiana, John Hillory Hood

Graduate Research Theses & Dissertations

This thesis examines implicit assumptions about democracy among Burmese residents in Chicago, Illinois and Fort Wayne, Indiana. A major focus of the research is the durability of foundational cultural models – basic, simple, widely-shared modes of thought – that may or may not change over time, measured in this study through length-of-residency. As such, I examined three distinct sample groups: temporary residents, immigrants, and adult offspring of immigrants. This research comprised methods of ethnography, semi-structured interviews, as well as a free-listing memory task. A key point of inquiry is intracultural variation occurring between sample groups. Particular attention was paid to …

The first essay investigates the employment effects of corporate taxation at the industry level; Specifically, do corporate taxes affect employment rates at the industry level and are the effects consistent across industries? This paper uses an identification strategy that exploits variation in corporate income tax rates across U.S. states and tries to understand how they impact industry employment at the county level with contiguous counties straddling state borders acting as controls. The results show that any change in the corporate tax rate affect the employment rate in goods …

Bivariate Cure Rate Model Using Copula Functions In Presence Of Censored Data And Covariates, Jie Huang

Graduate Research Theses & Dissertations

Bivariate survival cure rate models extend the understanding of time-to-event data by allowing for the formulation of more accurate and informative conclusion. These conclusions are obtainable from an analysis that accounts for a cured fraction of the population and dependence between paired units. We propose a mixture cure rate model where a correlation coefficient is used for the association between bivariate cure rate fractions and a new generalized Farlie Gumbel Morgenstern (FGM) copula function is applied to model the de-

pendence structure of bivariate survival times. Covariate effects are incorporated into two components of our model, cure rate fractions and …

Slavery's Soldiers: Armed Resistance In The Anglo-Atlantic, 1676-1823, Justin Iverson

Graduate Research Theses & Dissertations

Enslaved people resisted Atlantic chattel bondage in violent ways since the development of the trans-Atlantic slave trade. They also served as soldiers for White owners in various conflicts that also furthered White interests. Scholars of slavery and resistance in the Atlantic world have long held the belief that enslaved people in early America and the United States did not resist the Atlantic chattel system in the same ways or as frequently as other bond people in the Caribbean or Latin America. Moreover, enslaved soldiers are often portrayed as loyal subjects who fought in war and armed conflict to advance imperial …

Principals' Perceptions Of Professional Development And Caring Communities For English Learners, Sunny Sue Chang Jonas

Graduate Research Theses & Dissertations

A growing population of English Learners (ELs) have unique challenges when navigating the American educational system. In fact, there is an achievement gap such that EL students lag behind their native English peers in school outcomes. Accordingly, there is increased demand for professional development (PD) lead by principals to address the needs of the changing population of ELs. To support effective PD aimed at improved achievement for ELs, principals need embrace transformative thinking in their work. Although PD has the potential to be the driving force of change, traditional approaches to PD have limited impact on academic success of ELs. …

Evaluation Of Epilepsy Surgery Using Bayesian Multinomial Regression, Kacy Danielle Kane

Graduate Research Theses & Dissertations

We are exploring the effectiveness of brain surgeries that are supposed to eliminate or reduce the frequency of seizures in young Epilepsy patients. The long-term effectiveness of brain surgeries is evaluated by ordinal categories and brings longitudinal categorical responses.

Using a Bayesian multinomial regression model we examine the responses by the lobe of brain and other covariates as well as time. To overcome computational difficulties we utilize latent variables for multinomial responses and compare the results with frequentists methods.

Proper Orthogonal Decomposition Analysis Of Lid-Driven Cavity Flows Containing Particle Suspensions., Nitin Katiki

Graduate Research Theses & Dissertations

Previous experiments done on the square lid driven cavity have shown that its stability and transitional behavior, and by extension the behavior of more complex flows, can be greatly modified by introducing systematic disturbances called perturbations to its flow field. In this study, a square lid driven cavity is calculated in two-dimensional space and perturbed by means of particles suspended in the flow. The perturbations manifest as subtle changes in the flow field velocity and overall flow structure, these are caused by the particle-fluid drag interaction and the particle-particle collision interaction. To understand the nature of these changes and their …

Temporal Dynamics Of Human Emotional Response To Aversive Stimuli, Joseph Lawence Kempel

Graduate Research Theses & Dissertations

Emotions are an integral part of human expression and are often communicated nonverbally through behavioral actions. With advancements in electroencephalography (EEG) technology it is now possible to measure the dynamics of emotion generation in an individual on the basis of patterns in their brain activity. This thesis aims to model the temporal dynamics of human emotion generation upon exposure to aversive stimuli and measure the effect of external distractions as a viable emotion regulation strategy.

This research builds on previous work in the literature that has shown that the ability of humans to regulate their emotions intrinsically (based on their …

New Synthetic Methods Using Superelectrophiles, Sean Kennedy

Graduate Research Theses & Dissertations

The work outlined in this dissertation describes new synthetic methods in the synthesis of heterocyclic compounds mediated by superacid catalysis. Superacids are powerful reagents that enhance the reactivity of electrophiles, thereby opening the door to new reactive pathways with very weak nucleophiles. In this work, trifluoromethanesulfonic acid (triflic acid, CF3SO3H) is employed as a superacid catalyst to effect new transformations. These concepts are summarized in chapter 1. Chapter 2 describes a new acid-catalyzed cascade leading to the indolizidine ring system, which is present in a number of natural products. Experiments support a proposed mechanism involving vinylogous keto-enol tautomerization. The synthesis …

The Association Of Victimization And Depression: An Investigation Of The Implicated Factors Of Social Anxiety, Body Esteem, And Social Support, Jacqueline Jo Klossing

Graduate Research Theses & Dissertations

Victimization is an experience that affects a substantial portion of the adolescent population, and it is well established that it is associated with a host of negative outcomes, including depression. While the relations between victimization and depression have been researched extensively, there are a number of factors that may contribute to this association. Furthermore, both internal and external factors can play a role. Internally, the unique attribute of being socially anxious as well as the perceptions one carries regarding their appearance (i.e., body esteem) are implicated as potential mediators between victimization and depression. Externally, the social support an adolescent perceives …

Energy Re-Investment, Hari M. Osofsky, Jacqueline Peel, Brett H. Mcdonnell, Anita Foerster

Faculty Scholarship

Despite worsening climate change threats, investment in energy — in the United States and globally — is dominated by fossil fuels. This Article provides a novel analysis of two pathways in corporate and securities law that together have the potential to shift patterns of energy investment.

The first pathway targets current investments and corporate decision-making. It includes efforts to influence investors to divest from owning shares in fossil fuel companies and to influence companies to address climate change risks in their internal decision-making processes. This pathway has received increasing attention, especially in light of the Paris Agreement and the Trump …

The Treatment Of Contaminated Water Using Electrocoagulation, Adebayo Edward Adejinle

Graduate Research Theses & Dissertations

Wastewater treatment is a process that is used to remove significant amount of contaminant concentration from wastewater, which prevents harm to the environment. Chemical coagulation (CC) is one of the most influential processes used to remove contaminants, and it is the addition of chemicals called coagulants, which causes particles to stick together forming bigger flocs. However, as effective as CC is, it requires bench scale testing for determining the appropriate dosing rate for specific raw water properties, which makes the process time consuming. To eliminate these issues, the introduction of the Electrocoagulation (EC) process is considered. The EC process is …

Graduate Research Theses & Dissertations

This study examines the impact of the Performance Evaluation Reform Act (PERA) and Senate Bill 7 (SB7) on evaluative practices utilized with tenured educators within Illinois. Given the sense of urgency brought to bear on teacher quality from laws such as No Child Left Behind (NCLB) and Race To The Top (RTTT), revisions to the law that include streamlined processes, uniform evidence gathering and interpretation, and student growth measures are mainstays of legislation like PERA and SB7. Akin to many states, Illinois schools are working to institutionalize these concepts into everyday practices.

In reviewing the changes made to the Illinois …

Sky Surveys Scheduling Using Reinforcement Learning, Andres Felipe Alba Hernandez

Graduate Research Theses & Dissertations

Modern cosmic sky surveys (e.g., CMB S4, DES, LSST) collect a complex diversity of astronomical objects. Each of class of objects presents different requirements for observation time and sensitivity. For determining the best sequence of exposures for mapping the sky systematically, conventional scheduling methods do not optimize the use of survey time and resources. Dynamic sky survey scheduling is an NP-hard problem that has been therefore treated primarily with heuristic methods. We present an alternative scheduling method based on reinforcement learning (RL) that aims to optimize the use of telescope resources for scheduling sky surveys.

We present an exploration of …

Impact Of Social Support During A Social Interaction On Post-Trauma Cognitions And Outcomes During A Trauma Analogue Design, Christy Elizabeth Allen

Graduate Research Theses & Dissertations

This study utilized the trauma film paradigm to explore interpersonal processes in post-trauma social interactions and their relation to posttraumatic stress disorder (PTSD) symptoms within the framework of social-cognitive theory. Social support following a traumatic experience has been consistently linked with posttraumatic outcomes and PTSD symptoms, yet the exact mechanisms underlying this relationship remain unconfirmed. One theory is that when trauma survivors emotionally and cognitively process the traumatic experience within positive supportive conversations, these conversations can result in fewer negative posttraumatic cognitions, beliefs, and appraisals that have been linked to symptoms of PTSD. Likewise, negative support can create and reinforce …

Solving The Semidefinite Programming Relaxation Of Max-Cut Using An Augmented Lagrangian Method, Ahmed Sabah Al-Jilawi

Graduate Research Theses & Dissertations

Semidefinite programming (SDP) problems have been investigated and solved in this work. A novel approach has been introduced and validated to solve SDP relaxations of binary quadratic optimization problems. In the BiqCrunch solver, a penalty method is used to compute the solution of a semidefinite relaxation of a binary quadratic problem. This problem generates a bound on the optimal value of the original problem. A branch-and- bound approach then uses this semidefinite bound to solve the binary quadratic problems. In this study, a new approach has been developed to replace the penalty method with the augmented Lagrangian method. Also, according …

The Link Between Antibiotic Resistance Used For Recombinant Dna Selection And Cellular Phenotype In Rat Liver Epithelial Cells, Doaa Alshammari

Graduate Research Theses & Dissertations

Recombinant DNA plasmids are often used to mediate forced gene overexpression or suppression in mammalian cells, to address questions regarding the role of specific proteins in cell behavior and function. To select for cells harboring such recombinant plasmids, lethal antibiotics such as Puromycin, Geneticin (Neomycin) and Zeocin are frequently used, as plasmids contain selective antibiotic resistance genes that biochemically disarm them. Antibiotic resistance, induced by plasmid-borne genes and chronic exposure to lethal antibiotics can likewise potentially change the phenotype of cells, confounding the conclusions drawn from experiments on gene overexpression or suppression. Yet, little is known about the effects of …

Lewis Base Promoted Annulations Of Allenoates With 1,4-Naphthoquinones, Nicole Marie Shoup

Electronic Theses and Dissertations

Lewis base promoted cyclization of allenoates with electron deficient olefins open up the possibility to generate more complex organic structures. By generating more complex molecules, we are able to produce new compounds for biomedical and material applications. Both phosphine and amine Lewis bases offer interesting annulations with allenoates resulting in Lu or Morita–Baylis–Hillman type reactions. Once the Lewis base engages with the allenoate there can be several modes of nucleophilic reactivity that allows for the allenic ester to act as a two or three carbon synthon. The allenoate can then react with varying electron deficient olefins generating more complex molecules …
