The Hispanic Paradox And Older Adults’ Disabilities: Is There A Healthy Migrant Effect?, Esme Fuller Thomson, Amini Nuru-Jeter, Dawn M. Richardson, Ferrah Raza, Meredeth Minkler

Community Health Faculty Publications and Presentations

The “Hispanic Paradox” suggests that despite rates of poverty similar to African Americans, Hispanics have far better health and mortality outcomes, more comparable to non-Hispanic White Americans. Three prominent possible explanations for the Hispanic Paradox have emerged. The “Healthy Migrant Effect” suggests a health selection effect due to the demands of migration. The Hispanic lifestyle hypothesis focuses on Hispanics’ strong social ties and better health behaviors. The reverse migration argument suggests that the morbidity profile in the USA is affected when many Hispanic immigrants return to their native countries after developing a serious illness. We analyzed data from respondents aged …

Evaluating High School Students' Constitutional And Civic Literacy: A Case Study Of The Washington, D.C. Chapter Of The Marshall-Brennan Constitutional Literacy Project, Maryam Ahranjani, Caleb Medearis, Jeff Shook

Scholarly Works

The United States maintains a reputation as a vibrant, participatory democracy. Yet, paradoxically, formal civics education has essentially disappeared from America's public high schools, particularly urban public schools serving low-income and minority students. The Marshall-Brennan Constitutional Literacy Project, which is offered at almost zero cost to public schools and districts, developed as a response to the need for civics education in high schools and as a way to train future lawyers in public speaking, leadership, and counseling. To support the growth of the Marshall-Brennan project all over the country, the authors of this Essay came together to study the Marshall-Brennan …

Narrative Versus Nonnarrative: The Role Of Identification, Transportation And Emotion In Reducing Health Disparities, Sheila T. Murphy, Lauren B. Frank, Joyee S. Chatterjee, Lourdes Baezconde-Garbanati

Communication Faculty Publications and Presentations

This research empirically tests whether using a fictional narrative produces a greater impact on health-related knowledge, attitudes, and behavioral intention than presenting the identical information in a more traditional, nonfiction, non-narrative format. European American, Mexican American, and African American women (N = 758) were surveyed before and after viewing either a narrative or non-narrative cervical cancer-related film. The narrative was more effective in increasing cervical cancer-related knowledge and attitudes. Moreover, in response to the narrative featuring Latinas, Mexican Americans were most transported, identified most with the characters, and experienced the strongest emotions. Regressions revealed that transportation, identification with specific characters, …

What's Left To Remedy Wage Theft? How Arbitration Mandates That Bar Class Actions Impact Low-Wage Workers, Nantiya Ruan

Scholarly Works

For low-wage workers who suffer “wage theft” – employers illegally withholding portions of their wages – the dollars missing from their paychecks violate existing law and significantly impact the well-being of individuals, families, and communities. Despite this dire societal problem, the Supreme Court continues “closing the courtroom doors” in two ways: allowing employers to force workers out of court and into private arbitration; and prohibiting aggregate claims. Such trends, in combination, silence wage theft, leaving many claims unheard while unscrupulous employers gain direct advantage.

This Article explains how various procedural rulings have combined to prevent meaningful redress for wage theft. …

Interpreting Individual Classifications Of Hierarchical Networks, Will Landecker, Michael David Thomure, Luis M.A. Bettencourt, Melanie Mitchell, Garrett T. Kenyon, Steven P. Brumby

Computer Science Faculty Publications and Presentations

Hierarchical networks are known to achieve high classification accuracy on difficult machine-learning tasks. For many applications, a clear explanation of why the data was classified a certain way is just as important as the classification itself. However, the complexity of hierarchical networks makes them ill-suited for existing explanation methods. We propose a new method, contribution propagation, that gives per-instance explanations of a trained network's classifications. We give theoretical foundations for the proposed method, and evaluate its correctness empirically. Finally, we use the resulting explanations to reveal unexpected behavior of networks that achieve high accuracy on visual object-recognition tasks using well-known …

Inverted Takotsubo Cardiomyopathy And The Fundamental Diagnostic Role Of Echocardiography, Arantza Manzanal, Lara Ruiz, Jose Madrazo, Majesh Makan, Julio Perez

The Texas Heart Institute Journal

Takotsubo cardiomyopathy is characterized by the development of transient focal wall-motion abnormalities that involve the apical and midventricular segments, in the absence of obstructive coronary artery disease. A variant, inverted takotsubo cardiomyopathy, was described in 2010. We report 3 cases in which each patient's transthoracic echocardiogram revealed the characteristic basal and midventricular segmental akinesis of this variant. This pattern is not associated with coronary artery distribution, and it therefore can be differentiated from coronary artery disease with the use of echocardiography, by evaluating the distribution and temporal changes of akinetic areas.

Predicting Early Death After Cardiovascular Surgery By Using The Texas Heart Institute Risk Scoring Technique (Thirst), Saurabh Sanon, Vei-Vei Lee, Macarthur A Elayda, Sreedevi Gondi, James J Livesay, George J Reul, James M Wilson

The Texas Heart Institute Journal

Preoperative risk-prediction models are an important tool in contemporary surgical practice. We developed a risk-scoring technique for predicting in-hospital death for cardiovascular surgery patients. From our institutional database, we obtained data on 21,120 patients admitted from 1995 through 2007. The outcome of interest was early death (in-hospital or within 30 days of surgery). To identify mortality predictors, multivariate logistic regression was performed on data from 14,030 patients from 1995 through 2002 and risk scores were computed to stratify patients (low-, medium-, and high-risk). A recalibrated model was then created from the original risk scores and validated on data from 7,090 …

Mitochondrial Cardiomyopathy: Pathophysiology, Diagnosis, And Management, Deborah E Meyers, Haseeb Ilias Basha, Mary Kay Koenig

The Texas Heart Institute Journal

Mitochondrial disease is a heterogeneous group of multisystemic diseases that develop consequent to mutations in nuclear or mitochondrial DNA. The prevalence of inherited mitochondrial disease has been estimated to be greater than 1 in 5,000 births; however, the diagnosis and treatment of this disease are not taught in most adult-cardiology curricula. Because mitochondrial diseases often occur as a syndrome with resultant multiorgan dysfunction, they might not immediately appear to be specific to the cardiovascular system. Mitochondrial cardiomyopathy can be described as a myocardial condition characterized by abnormal heart-muscle structure, function, or both, secondary to genetic defects involving the mitochondrial respiratory …

Feasibility Of Temporary Biventricular Pacing After Off-Pump Coronary Artery Bypass Grafting In Patients With Reduced Left Ventricular Function, Daniel Y Wang, Lauren A Kelly, Marc E Richmond, T Alexander Quinn, Bin Cheng, Michelle D Spotnitz, Santos E Cabreriza, Yoshifumi Naka, Allan S Stewart, Craig R Smith, Henry M Spotnitz

The Texas Heart Institute Journal

In selected patients undergoing cardiac surgery, our research group previously showed that optimized temporary biventricular pacing can increase cardiac output one hour after weaning from cardiopulmonary bypass. Whether pacing is effective after beating-heart surgery is unknown. Accordingly, in this study we examined the feasibility of temporary biventricular pacing after off-pump coronary artery bypass grafting.

The effects of optimized pacing on cardiac output were measured with an electromagnetic aortic flow probe at the conclusion of surgery in 5 patients with a preoperative mean left ventricular ejection fraction of 0.26 (range, 0.15–0.35). Atrioventricular (7) and interventricular (9) delay settings were optimized in …

The Effect Of Focused Extracorporeal Shock Wave (Esw) On Calvaria Bone Ex Vivo, Syrah Imtiaz Quraishi

Master's Theses (2009 -)

Introduction: Extracorporeal shock wave (ESW) is low frequency high-pressure wave, regularly used to destroy calcifications e.g. kidney stone. Recent evidence shows that ESW produces micro-cracks in the bones of horse legs. As micro-cracks in bone can lead to an increased rate of bone turnover (remodeling), we hypothesize that proper application of ESW will increase bone turnover rate through generating micro-cracks in bone.

Materials and Methods: To test our hypothesis, we used a mouse calvaria bone organ culture model and explored the effects of ESW on bone tissues ex vivo. The calvaria bone pieces were collected from 3 days old C57BL/6 …

Queering The Catalog: Queer Theory And The Politics Of Correction, Emily Drabinski

Publications and Research

Critiques of hegemonic library classification structures and controlled vocabularies have a rich history in information studies. This project has pointed out the trouble with classification and cataloging decisions that are framed as objective and neutral but are always ideological and worked to correct bias in library structures. Viewing knowledge organization systems from a queer perspective, however, challenges the idea that classification and subject language can ever be finally corrected. Engaging queer theory and library classification and cataloging together requires new ways of thinking about how to be ethically and politically engaged on behalf of marginal knowledge formations and identities who …

Exploring Realism And Magical Realism In Slum Novels Of The Global South, Benjamin Hawkins

University Honors Theses

In this research I compare the magical realist novel Berji Kristin: Tales from the Garbage Hills by Latife Tekin with Chris Abani's GraceLand in order to combat the assertion that magical realism, because it is a non-Western mode, is intrinsically more appropriate for representations of extreme poverty in the third world than realism. To ground the aesthetic discussion to issues facing slum communities like those central in GraceLand and Berji Kristin, I use Rob Nixon's book Slow Violence and the Environmentalism of the Poor in which he posits that ecological degradation of the poor's living spaces through oil spills, toxic …

An Inquiry Into The Division Of Labor, Raul Reyes

University Honors Theses

This inquiry seeks to establish that Adam Smith relies upon his books The Theory of Moral Sentiments [1959] and An Inquiry Into the Nature and Causes of the Wealth of Nations [1776] as complementary texts to introduce and develop his ideas. We will begin with a background of economic thinkers prior to Smith. After summarizing an example of this division of labor by Adam Smith, we will delve into the benefits of the division of labor: more skilled workers, time efficiency, and the invention of proper machinery. Similarly, we will examine the implications brought by this division of labor with …

Hemispheric Processing Of Vocal Emblem Sounds, Yael Neumann-Werth, Erika Levy, Loraine Obler

Publications and Research

Vocal emblems, such as shh and brr, are speech sounds that have linguistic and nonlinguistic features; thus, it is unclear how they are processed in the brain. Five adult dextral individuals with left-brain damage and moderate– severe Wernicke’s aphasia, five adult dextral individuals with right-brain damage, and five Controls participated in two tasks: (1) matching vocal emblems to photographs (‘picture task’) and (2) matching vocal emblems to verbal translations (‘phrase task’). Cross-group statistical analyses on items on which the Controls performed at ceiling revealed lower accuracy by the group with left-brain damage (than by Controls) on both tasks, and …

Tarrying With The "Private Parts", Robert F. Reid-Pharr

Publications and Research

Two-thirds of the way through Object Lessons (2012), Robyn Wiegman's provocative study of the institutional and ideological development of what she names identity-based modes of inquiry in US colleges and universities, the author recounts a 2003 trip she took to Leiden to attend the inaugural meeting of the International American Studies Association. There, she was regularly met with the claim that American studies, at least as it is practiced by citizens and long-term residents of the United States, was deeply provincial and too caught up with rehearsals of the humdrum difficulties of American social and cultural life, particularly our always …

Risk Management Strategies For Commodity Processors, Songjiao Chen

Agribusiness and Applied Economics

Recent years have witnessed an increase in agricultural commodity price volatility. This thesis analyzes different models to derive optimal hedge strategies for commodity processors, with two components addressed. One is the dependence structure and joint distribution among inputs, outputs, and hedging instruments that impact hedging effectiveness. The second refers to different procurement and sales scenarios a processor may encounter. A domestic flour mill company is used to demonstrate alternative hedging strategies under different processing scenarios. Copula is a relatively new method used to capture flexible dependence structure and joint distribution among assets. The applications of copulas in the agricultural literature …

Do Cryoconite Holes Have The Potential To Be Significant Sources Of C, N, And P To Downstream Depauperate Ecosystems Of Taylor Valley, Antarctica?, Elizabeth A. Bagshaw, Martyn Tranter, Andrew G. Fountain, Kathleen A. Welch, Hassan J. Basagic, W. Berry Lyons

Geology Faculty Publications and Presentations

Nutrient recycling occurs in hydrologically isolated cryoconite holes on the glaciers of the McMurdo Dry Valleys, Antarctica. Biogeochemical processes enrich the cryoconite holes with solute and nutrients compared to the source sediment and glacier ice. The position of the glacier within the landscape affects the physical and biogeochemical character of the cryoconite holes, with those found in more biologically productive areas of the valley having higher concentrations of C, N, and P and higher pH. Comprehensive assessment of the quality and quantity of bioavailable C, N, and P shows that the cryoconite holes represent a significant store of nutrient in …

Filling In Missing Values In The North Dakota Land Valuation Model, Laura Beth Laufmann

Agribusiness and Applied Economics

The North Dakota Land Valuation Model relies on a crop yield data set published by the USDA's National Agricultural Statistics Service. Over the years this data set, due to the way in which the data is collected, has developed a growing problem with missing values. This research utilizes a secondary data set and the spatial nature of the crop yield data to develop a new methodology for interpolating the missing values in the NASS data set. This methodology uses the secondary data set to establish the spatial nature of the yield data and to build spatial weights matrices. These spatial …
