Association Between Left Ventricular Mechanics And Diffuse Myocardial Fibrosis In Patients With Repaired Tetralogy Of Fallot: A Cross-Sectional Study, Christopher M. Haggerty, Jonathan D. Suever, Arichanah Pulenthiran, Abba Mejia-Spiegeler, Gregory J. Wehner, Linyuan Jing, Richard J. Charnigo, Brandon K. Fornwalt, Mark A. Fogel

Biomedical Engineering Faculty Publications

Background: Patients with repaired tetralogy of Fallot (TOF) have progressive, adverse biventricular remodeling, leading to abnormal contractile mechanics. Defining the mechanisms underlying this dysfunction, such as diffuse myocardial fibrosis, may provide insights into poor long-term outcomes. We hypothesized that left ventricular (LV) diffuse fibrosis is related to impaired LV mechanics.

Methods: Patients with TOF were evaluated with cardiac magnetic resonance in which modified Look-Locker (MOLLI) T1-mapping and spiral cine Displacement encoding (DENSE) sequences were acquired at three LV short-axis positions. Linear mixed modeling was used to define the association between regional LV mechanics from DENSE based on regional T1-derived diffuse …

Constructing A Grammatically Enriched Children's Book, Rebecca Ebert

Honors Projects

The intended purpose of this book is to serve as a grammatically rich resource of the grammatical structure: third person singular present tense. It is targets preschool age children with or at risk for a specific language impairment (SLI). More specifically, this book can be used as a clinical tool by speech-language pathologists in order to assist those with language delays in acquiring this difficult structure. Third person singular present tense is a morpheme that is acquired later in child language development due to its complexity, rarity and acoustic factors. Creating a clinical resource with an abundance of third person …

Impacts Of Power System-Tied Distributed Generation On The Performance Of Protection Systems, Terver T. Maor

Electrical Engineering Theses

The dispersed integration of smaller power units in the existing utility grid is the new trend. This is largely due to changes in the power generation and distribution markets. The combination of rising cost of new construction, deregulations and improved newer power equipment technologies suitable for deferred expansions make the new trend very attractive to power companies and independent investors. Until recently, other contributions to power distribution systems from such sources as standby units were considered negligible and therefore unaccounted for during the design and operation of power systems. This view has drastically changed, largely due to the increasing penetration …

The Impact Of Reduced Arctic Sea Ice Extent On Cryospheric Snowfall, Alexander Carne

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Satellite observations show that sea ice extent in the Arctic has been declining from 1979 through present day, reaching record minimum extents in 2007 and 2012. Reduced sea ice extent allows for greater expanses of open water to interact with the Arctic atmosphere, potentially leading to changes in the Arctic climate. The greatest declines in Arctic sea ice extent have occurred in summer and autumn. During these seasons, it is likely that the decrease in Arctic sea ice extent led to an increase in atmospheric sensible and latent heat fluxes, possibly leading to increases in Arctic temperature and moisture. Increases …

Oxygen Isotopic Composition Of Nitrate Produced By Freshwater Nitrification, Danielle Boshers

Master's Theses

Identifying sources of nitrate (NO₃^-) in the environment is important to elucidate causes of water quality impairment and eutrophication. Measurements of naturally occurring stable isotope ratios of nitrogen (¹⁵N/¹⁴N) and oxygen (¹⁸O/¹⁶O) in NO₃^-, can be used to determine the sources, dispersal, and fate of natural and contaminant NO₃^- in aquatic environments. To this end, it is necessary to know how NO₃^- isotopologues are modified by biological reactions, as heavy and light isotopes have different reaction rates. One important microbial reaction that …

Moving Beyond Lassiter: The Need For A Federal Statutory Right To Counsel For Parents In Child Welfare Cases, Vivek S. Sankaran

Articles

In New York City, an indigent parent can receive the assistance of a multidisciplinary legal team—an attorney, a social worker, and a parent advocate—to defend against the City’s request to temporarily remove a child from her care. But in Mississippi, that same parent can have her rights to her child permanently terminated without ever receiving the assistance of a single lawyer. In Washington State, the Legislature has ensured that parents ensnared in child abuse and neglect proceedings will receive the help of a well-trained and well-compensated attorney with a reasonable caseload. Yet in Tennessee, its Supreme Court has held that …

Law's Haze, Police Ways, And Tech's Maze: Relationships Between American Law, Crime, And Technology, Meghan Peterson

Doctoral Dissertations

In this dissertation, I explore the role of law in policing operations targeting cyber sex offenders in the United States. Specifically, I examine enforcement in this crime arena as part of an ongoing expansion within the carceral, surveillance, risk-based state. I argue that imprecision and lack of clarity within American law – particularly in the evolving world of online interactions – generate hazy, arbitrary applications in law enforcement. On this point, I submit that absence of legal clarity undermines law enforcement efforts to address crimes – both within and beyond the cyber world. Distinctive spaces of online and tech-based socialization, …

Creative Self-Efficacy As Mediator Between Creative Mindsets And Creative Problem-Solving, Ryan Royston, Roni Reiter-Palmon

Psychology Faculty Publications

An emerging area of research is how one's mindset regarding the fixedness and malleability of creative ability relates to creative performance. Malleable creative mindsets tend to be positively related to creativity while fixed mindsets often show a negative association. Similarly, creative self-efficacy, or one's beliefs that they have the capacity to be creative, is also related to creative performance and creative mindsets. While previous studies tested the direct relationship between mindsets and creativity, this study tested creative self-efficacy in this relationship. A total of 152 students from a Midwestern university participated in the study. They were provided with measures of …

Repeat Abortion In Chinese Adolescents: A Cross-Sectional Study In 30 Provinces, Jinlin Liu, Shangchun Wu, Jialin Xu, Marleen Temmerman, Wei-Hong Zhang

Obstetrics and Gynaecology, East Africa

Background: Premarital sex has become more acceptable in China nowadays. The Chinese Family Planning (FP) programme mainly focuses on married couples, and young unmarried women have little access to information or advice about contraception. Abortion is commonly used to end unintended pregnancies in China. This study aimed to determine risk factors related to repeat abortions in Chinese adolescents.

Methods: This cross-sectional study was one component of an EU-funded project and was conducted between March 20, and Oct 5, 2013 in China. We collected data using a questionnaire filled by abortion service providers for all women seeking abortions within 12 weeks …

Do Neonatal Nurses Caring For Newborns With Neonatal Abstinence Syndrome (Nas) Whose Mothers Used Illicit Substances During Pregnancy Experience Moral Distress? A Pilot Study, Valarie Artigas

Doctoral Dissertations

Maternal substance misuse/abuse during pregnancy may lead to adverse neonatal outcomes, including neonatal abstinence syndrome (NAS). NAS is a constellation of withdrawal symptoms exhibited in newborns in response to the discontinuance of in-utero exposure to licit and illicit substances. The incidence of NAS is directly related to the increasing rates of maternal substance use/abuse. The United States has experienced a five-fold increase of newborns born with NAS. The care of the newborn with NAS is one of the most challenging conditions for the neonatal nurse. Management of newborns with NAS requires knowledge that has not been traditionally partnered within care …

Super-Diversity As A Methodological Approach: Re-Centering Power And Inequality, Sofya Aptekar

Publications and Research

Super-diversity as a methodological lens calls for a study of dynamics of new and diversified social groups that moves away from more traditional approaches focused on ethnicity. In examining the potential of super-diversity as a methodological lens, I identify a risk of downplaying the effect of “old” categories of difference that are likely to continue to shape social structures as well as space. I propose a re-centering of power and inequality in the study of super-diversity by situating its study within an urban culturalist approach, with sociological tools borrowed from ethnomethodology and symbolic interactionism. This proposal is illustrated through the …

A Comparison Of The Social-Adaptive Perspective And Functionalist Perspective On Guilt And Shame, Heidi L. Dempsey

Research, Publications & Creative Work

Within the field of guilt and shame two competing perspectives have been advanced. The first, the social-adaptive perspective, proposes that guilt is an inherently adaptive emotion and shame is an inherently maladaptive emotion. Thus, those interested in moral character development and psychopathology should work to increase an individual’s guilt-proneness and decrease an individual’s shame-proneness. The functionalist perspective, in contrast, argues that both guilt and shame can serve a person adaptively or maladaptively—depending on the situational appropriateness, duration, intensity, and so forth. This paper reviews the research conducted supporting both positions; critiques some issues with the most widely used guilt- and …

A Simple And Accurate Rule-Based Modeling Framework For Simulation Of Autocrine/Paracrine Stimulation Of Glioblastoma Cell Motility And Proliferation By L1cam In 2-D Culture., Justin Caccavale, David Fiumara, Michael Stapf, Liedeke Sweitzer, Hannah J. Anderson, Jonathan Gorky, Prasad Dhurjati, Deni S. Galileo

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Glioblastoma multiforme (GBM) is a devastating brain cancer for which there is no known cure. Its malignancy is due to rapid cell division along with high motility and invasiveness of cells into the brain tissue. Simple 2-dimensional laboratory assays (e.g., a scratch assay) commonly are used to measure the effects of various experimental perturbations, such as treatment with chemical inhibitors. Several mathematical models have been developed to aid the understanding of the motile behavior and proliferation of GBM cells. However, many are mathematically complicated, look at multiple interdependent phenomena, and/or use modeling software not freely available to the research …

Iron Reduction Response And Demographic Differences Between Diabetics And Non-Diabetics With Cardiovascular Disease Entered To A Controlled Clinical Trial, Leo Zacharski, Galina Shamayeva, Bruce Chow

Dartmouth Scholarship

Iron-catalyzed oxygen free radical-induced oxidative stress mediates the pathogenesis of diabetes and cardiovascular disease (CVD). Diabetics (n=473) and non-diabetics (n=804) with CVD entered to a randomized trial of iron (ferritin) reduction by calibrated phlebotomy (www.clinicaltrials.gov, Identifier NCT00032357) had comparable iron measures at entry but diabetics had greater burden of CVD and comorbidities, lower hemoglobin and hematocrit levels, and higher glucose levels than non-diabetics. Entry iron measures were lower in diabetics on hypoglycemic therapy compared to diabetics untreated previously. Diabetics and non-diabetics had comparable iron measures during follow-up. Loess analysis of paired ferritin and hemoglobin, and paired ferritin and glucose levels …

A Way Of Reflecting On Identity: The Five Stories Of The Conflicting Relationships In Nepal, Tomoki Yamanaka

Capstone Collection

Conflict studies show that the components of identity are interrelated to sources and dynamics of conflict in intricate ways. This study self-reflectively explores a way of reflecting on identity from the links between conflict and identity through a qualitative study of the five stories of the conflicting relationships in Nepal. By analyzing the stories collected through in-depth interviews with Nepali peace workers, an element of power in group differences was noted. This illustrated the challenge of having the voices of those being marginalized heard amongst conflicting issues around them. Those that were interviewed also struggled with the challenge of having …

Expression And Role Of Gonadotropin-Releasing Hormone 2 And Its Receptor In Mammals, Amy Desaulniers, Rebecca A. Cederberg, Clay A. Lents, Brett R. White

Department of Animal Science: Faculty Publications

Gonadotropin-releasing hormone 1 (GnRH1) and its receptor (GnRHR1) drive mammalian reproduction via regulation of the gonadotropins. Yet, a second form of GnRH (GnRH2) and its receptor (GnRHR2) also exist in mammals. GnRH2 has been completely conserved throughout 500 million years of evolution, signifying high selection pressure and a critical biological role. However, the GnRH2 gene is absent (e.g., rat) or inactivated (e.g., cow and sheep) in some species but retained in others (e.g., human, horse, and pig). Likewise, many species (e.g., human, chimpanzee, cow, and sheep) retain the GnRHR2 gene but lack the appropriate coding sequence to produce a full-length …
