Effects Of Two Prereading Activities On Comprehending Science Text: Reading Abridged Text And Learning Vocabulary Words, Audrey J. Fowler

Dissertations, Theses, and Capstone Projects

The present study examined the effects of two prereading activities designed to improve fifth-grade students’ vocabulary learning and comprehension of science textbook content containing those words. Ninety-three fifth grade students participated in this study. The prereading activities consisted of students reading an abridged version of the text or receiving instruction on vocabulary words drawn from the text before reading the full text once. Students receiving these treatments were compared to a control condition in which students reread the full text passage twice but did not receive any prereading treatment. Students were grouped by reading ability levels into above average, average, …

(Dis)Entangling Gender Expression And Race In Antigay Discrimination: An Intersectional Approach, Steph M. Anderson

Dissertations, Theses, and Capstone Projects

Current psychological definitions and operationalizations of antigay discrimination conceptualize negative treatment of lesbian, gay, bisexual and queer (LGBQ) individuals as a response to their same-gender sexual orientations and not other factors. Because an individual’s sexual orientation is always understood through racialized hegemonic gender ideologies, however, attention to gender expression – how one “does” gender – and dynamics of race within antigay encounters is essential. Comprised of two mixed-method studies, this dissertation examines the role of gender expression and race in antigay discriminatory encounters from two perspectives: those who are targets of discrimination (i.e., cisgender and transgender LGBQ individuals) and those …

Scale Up Bayesian Network Learning, Xiannian Fan

Dissertations, Theses, and Capstone Projects

Bayesian networks are widely used graphical models which represent uncertain relations between the random variables in a domain compactly and intuitively. The first step of applying Bayesian networks to real-word problems is typically building the network structure. Optimal structure learning via score-and-search has become an active research topic in recent years. In this context, a scoring function is used to measure the goodness of fit of a structure to given data, and the goal is to find the structure which optimizes the scoring function. The problem has been viewed as a shortest path problem, and has been shown to be …

Hearing Aid Use And Cognitive Function: A Systematic Review, Hershel Korngut

Dissertations, Theses, and Capstone Projects

This systematic review analyzed the research relating the use of hearing aids to cognitive function. Hearing aid use was examined to see if wearing hearing aids improves cognitive function, if the length of time hearing aids are worn impacts cognitive ability, if the type of hearing aid used has any impact on cognitive function, and if hearing aid use slows down cognitive decline. Ten studies met the criteria for this review. An analysis of the research revealed some evidence to support wearing hearing aids improves cognitive function, however, there is substantial evidence that shows no impact between wearing hearing aids …

Understanding School And Interethnic Relations Of Mexican Immigrant Youth In A Post-Industrial Community, Roberto Martinez

Dissertations, Theses, and Capstone Projects

There is a dearth of literature on how immigrant groups understand minority groups in the United States, in particular, African-Americans. Increased technology and more rapid global movement in the 21st Century challenges 20th explanations of assimilation (Chicago School) and necessitates more research focused on how immigrant groups and racialized minorities interact to negotiate new worlds. This ethnographic research was conducted over thirteen months during 2012 and 2013 in a post-industrial neighborhood in the northeast that had been the site of 11 purported anti-bias attacks against Mexican immigrants during the summer of 2010. Research questions focused on: 1) Mexican immigrant youth …

Darwinian Debunking Reconsidered, Amanda J. Favia

Dissertations, Theses, and Capstone Projects

What can evolutionary theory tell us about morality? From descriptive claims that explain morality as an evolved trait to normative (or prescriptive) claims that rely on evolution to describe how humans ought to behave, philosophers have debated whether or not evolutionary theory can or should inform moral theory. Most recently, the debate about evolutionary ethics has shifted to metaethics. In this case, philosophers have sought after evolutionary explanations in the hopes of resolving long-standing debates between moral realists and moral antirealists.

These metaethical debates have centered on what are called Darwinian debunking arguments. Proponents of the Darwinian debunking argument, …

Mechanisms Of Immune Activation And Suppression By Parasitic Wasps Of Drosophila, Johnny R. Ramroop

Dissertations, Theses, and Capstone Projects

Drosophila melanogaster has served as an excellent model organism to study the molecular processes of innate immunity. Flies essentially lack adaptive immunity and the innate immune system is often divided into the humoral and cellular responses (Lemaitre and Hoffmann 2007). The humoral arm involves the production of antimicrobial peptides, secreted from the fat body, to combat bacterial and fungal infections. The cellular response involves the production of hemocytes (blood cells: crystal cells, plasmatocytes, and lamellocytes) in the larval lymph gland, in the sessile pools, and in circulation (Gold and Bruckner 2014). Microbial pathogens are phagocytosed by plasmatocytes whereas larger parasites …

Social Isolation, Social And Emotional Loneliness, And Self-Reported Hearing Difficulties In Older Adults With Hearing Loss, Yuliya Borik

Dissertations, Theses, and Capstone Projects

Hearing loss is known to affect communicative ability and has been associated with poor health-related outcomes such as impaired cognition, increased risk for falls, and psychotic manifestations. Social isolation and loneliness are also widely recognized to negatively impact mental and physical health. The purpose of this systematic review is to review literature that explores a relationship between hearing loss with and/or without self-reported hearing difficulties and social isolation and social and emotional loneliness in older adults with hearing loss ranging from mild to profound. The goal is to determine whether there is a direct relationship between subjective and/or objective hearing …

The Words And Worlds Of Disability: Discourses On Disablement Within The Situated Practices Of Service Providers, Enitza C. Carril

Dissertations, Theses, and Capstone Projects

From a traditional perspective, disability stood outside the normal bounds of development, belonging within the realm of pathology and the disabled person was defined as deficient. Disability may also be characterized as an instance of human diversity and disabled as a designated identity that is socially constructed in an ongoing process—an interaction between individuals and social contexts. The process of disablement is linked to discourses used to define and act upon people ascribed with a disabled identity. This study assumes that disability is an instance of human diversity, a valid developmental trajectory, which is enacted and embedded in sociocultural, political, …

The Role Of The Ocean Economy In The National Income Accounts Of Indonesia, Matius Suparmoko

Journal of Ocean and Coastal Economics

This paper presents the role of the Ocean Economy in the National Income Accounts of

Indonesia including the concept and methodology used to estimate the contribution of

this ecosystem to Indonesian value added. Currently, the national income account of

Indonesia only recognizes the fishery sector. Fishery activities have been considered as

one of the sub-sectors of agricultural sector together with sub-sectors of farm food

crops, plantation or non-food crops, forestry, and livestock. There are some drawbacks

in the concept of national income accounts, since it follows the UN system of national

accounts (SNA) that recognize only economic sectors or activities …

Model For The Electrolysis Of Water And Its Use For Optimization, Roger Lascorz, Javier E. Hasbun Dr

Georgia Journal of Science

The goal of this research was to study the optimization of the electrolysis of water both theoretically and experimentally. For accuracy, 3 hr experiments were made with measurements recorded every 15 min. The results show that a better model than the classical one is needed for water electrolysis. A new model that fits experimental data better is proposed. The results of this new model not only predict hydrogen production in electrolysis of water better, but show a way to predict gas production of any liquid as well as what voltage to use to optimize it.

Role Of Histidine 547 Of Human Dopamine Transporter In Molecular Interaction With Hiv-1 Tat And Dopamine Uptake, Yaxia Yuan, Pamela M. Quizon, Wei-Lun Sun, Jianzhuang Yao, Jun Zhu, Chang-Guo Zhan

Molecular Modeling and Biopharmaceutical Center Faculty Publications

HIV-1 Tat plays an important role in HIV-associated neurocognitive disorders (HAND) by disrupting neurotransmission including dopamine uptake by human dopamine transporter (hDAT). Previous studies have demonstrated that HIV-1 Tat directly binds to hDAT and some amino-acid mutations that attenuate the hDAT-Tat binding also significantly decreased dopamine uptake activity of hDAT. This combined computational-experimental study demonstrates that histidine-547 (H547) of hDAT plays a crucial role in the hDAT-Tat binding and dopamine uptake by hDAT, and that the H547A mutation can not only considerably attenuate Tat-induced inhibition of dopamine uptake, but also significantly increase the V_max of hDAT for dopamine uptake. …

Data Associated With A Simplified Approach To Stakeholder Engagement In Natural Resource Management: The Five-Feature Framework, Jared L. Talley, Jen Schneider, Eric Lindquist

MILES Data Sets

This paper distills complex frameworks for stakeholder engagement to five main principles that scientists and natural resource managers can use in planning stakeholder engagement efforts. Many natural resource management professionals, including practitioners and scholars, increasingly recognize the need for and potential benefits of engaging stakeholders in complex decision-making processes, yet the implementation of these efforts varies wildly, reflecting great methodological and conceptual diversity. Given the dynamic and diverse natural resource management contexts in which engagement occurs and the often significant stakes involved in making decisions about natural resources, we argue that stakeholder engagement would benefit from a theoretical framework that …

X-Ray Characterization Of Mesophases Of Human Telomeric G-Quadruplexes And Other Dna Analogues, Jacob B. Schimelman, Nicole F. Steinmetz, Roger H. French

Faculty Scholarship

Observed in the folds of guanine-rich oligonucleotides, non-canonical G-quadruplex structures are based on G-quartets formed by hydrogen bonding and cation-coordination of guanosines. In dilute 5′-guanosine monophosphate (GMP) solutions, G-quartets form by the self-assembly of four GMP nucleotides. We use x-ray diffraction to characterize the columnar liquid-crystalline mesophases in concentrated solutions of various model G-quadruplexes. We then probe the transitions between mesophases by varying the PEG solution osmotic pressure, thus mimicking in vivo molecular crowding conditions. Using the GMP-quadruplex, built by the stacking of G-quartets with no covalent linking between them, as the baseline, we report the liquid-crystalline phase behaviors of …

Evolving Patterns: Conflicting Perceptions Of Cultural Preservation And The State Of Batik’S Cultural Inheritance Among Women Artisans In Guizhou, China, Katherine B. Uram

Lawrence University Honors Projects

My exploration features Miao batik-making in Guizhou Province and explores several sets of overlapping questions. The first set focuses on the status of the craft of Miao batik-making and the perceptions of its future. Is batik-making a dying art form? To what extent is Batik-making a thriving cultural practice today, or do Miao in China (and other ethnic groups involved in batik-making) perceive an inheritance crisis? My next focus is on the role of institutions and the tourism industry. If taught less and less in the domestic sphere (traditions passed from mother to daughter), what role do public domains such …

Mechanism Of Action And Applications Of Interleukin 24 In Immunotherapy, Leah Persaud, Dayenny De Jesus, Oliver Brannigan, Maria Richiez-Paredes, Jeannette Huaman, Giselle Alvarado, Linda Riker, Gissete Mendez, Jordan Dejoie, Moira Sauane

Publications and Research

Interleukin 24 (IL-24) is an important pleiotropic immunoregulatory cytokine, whose gene is located in human chromosome 1q32-33. IL-24’s signaling pathways have diverse biological functions related to cell differentiation, proliferation, development, apoptosis, and inflammation, placing it at the center of an active area of research. IL-24 is well known for its apoptotic effect in cancer cells while having no such effect on normal cells. IL-24 can also be secreted by both immune and non-immune cells. Downstream effects of IL-24, after binding to the IL-20 receptor, can occur dependently or independently of the JAK/STAT signal transduction pathway, which is classically involved in …

Neuroanatomical Alterations In High-Functioning Adults With Autism Spectrum Disorder, Tehila Eilam-Stock, Tingting Wu, Alfredo Spagna, Laura J. Egan, Jin Fan

Publications and Research

Autism spectrum disorder (ASD) is a pervasive neurodevelopmental condition, affecting cognition and behavior throughout the life span. With recent advances in neuroimaging techniques and analytical approaches, a considerable effort has been directed toward identifying the neuroanatomical underpinnings of ASD. While gray-matter abnormalities have been found throughout cortical, subcortical, and cerebellar regions of affected individuals, there is currently little consistency across findings, partly due to small sample-sizes and great heterogeneity among participants in previous studies. Here, we report voxel-based morphometry of structural magnetic resonance images in a relatively large sample of high-functioning adults with ASD (n = 66) and matched …

4,4’-Dichlorodiphenyltrichloroethane (Ddt) And 4,4’-Dichlorodiphenyldichloroethylene (Dde) Promote Adipogenesis In 3tl1 Adipocyte Cell Culture, J Kim, Q Sun, Y Yue, Kyong-Sup Yoon, K -Y Whang, J M. Clark, Y Park

SIUE Faculty Research, Scholarship, and Creative Activity

4,4’-Dichlorodiphenyltrichloroethane (DDT), a chlorinated hydrocarbon insecticide, was extensively used in the 1940s and 1950s. DDT is mainly metabolically converted into 4,4’- dichlorodiphenyldichloroethylene (DDE). Even though most countries banned DDT in the 1970s, due to the highly lipophilic nature and very stable characteristics, DDT and its metabolites are present ubiquitously in the environment, including food. Recently, there are publications on relationships between exposure to insecticides, including DDT and DDE, and weight gain and altered glucose homeostasis. However, there are limited reports regarding DDT or DDE and adipogenesis, thus we investigated effects of DDT and DDE on adipogenesis using 3T3-L1 preadipocytes. Treatment …

The 2013 Boston Marathon Attacks: An Experimental Investigation Of Worldview Change Following Film Re-Exposure To Mass Trauma, Ian A. Gutierrez

Master's Theses

Models of meaning making and post-traumatic growth contend that traumatic events are catalysts for significant and long-lasting change in a person’s worldview—that is, their beliefs about social, metaphysical, theological, and political reality. Nearly all tests of this contention have employed retrospective and cross-sectional methods. However, the limitations inherent in these designs preclude causal conclusions. The current study represents the first longitudinal, laboratory-based experimental examination of belief change following trauma exposure using the trauma film paradigm. Findings reveal that the trauma film paradigm can successfully induce posttraumatic affective responses with live news coverage of a mass trauma (i.e., the 2013 Boston …

Patient History Elicitation And Diagnostic Decision Making, Nicholas Iuliucci

Theses

Technology has changed the way people communicate, and communication between patients and medical professionals has not been exempt from these developments. Clinicians are now text messaging, emailing, and video conferencing patient. Understanding the impact of the new modalities on communication patterns is imperative to ensure quality care. Thirty-two medical professionals of varying experience conducted a patient interview with two confederate patients over an instant messaging system. The first interview was 15 minutes and the second 7 minutes, the latter condition inducing time pressure. The results demonstrated that time pressure has an adverse impact on the medical professionals’ communication patterns. The …

A Comparative Analysis Of Demographics And Reported Preferential Learning Modes Of Florida And Non-Florida Osher Lifelong Learning Institutes Members, Jung Min Lee

USF Tampa Graduate Theses and Dissertations

This research examined demographic factors and reported preferential learning mode among a sample of Florida Osher Lifelong Learning Institute (OLLI) members compared to a national sample profile of OLLI members. This study was prompted by an earlier study of OLLI members conducted by the National Resource Center (NRC) for OLLIs, which produced a national profile describing OLLI members. Although there was a national profile for OLLI members, there were no existing profiles of Florida OLLI members that could be used by OLLI administrators and instructors.

This study employed an online survey to compare data between the national OLLI member profile …

Targeting Tau Degradation By Small Molecule Inhibitors For Treatment Of Tauopathies, Mackenzie Martin

USF Tampa Graduate Theses and Dissertations

Tauopathies are neurodegenerative diseases that affect millions of people around the world. Tauopathies include more than 20 neurodegenerative diseases. Some of the most common tauopathies are Alzheimer’s disease (AD), frontotemporal dementia (FTD), chronic traumatic encephalopathy (CTE), Pick’s disease, corticobasal degeneration, progressive supranuclear palsy (PSP), agyrophillic grain disease, and amyotrophic lateral sclerosis (ALS). These diseases can cause significant memory loss, behavioral changes, motor deficits and speech impairments. Tauopathies stem from accumulation of the microtubule associated protein tau (MAPT). Tau stabilizes microtubules and helps with axonal transport. In a disease state tau becomes hyperphosphorylated and truncated leading to its aggregation. More recently …

Methylation Of The Glucocorticoid Receptor (Nr3c1) In Placenta Is Associated With Infant Cry Acoustics, Stephen J. Sheinkopf, Giulia Righi, Carmen J. Marsit, Barry M. Lester

Dartmouth Scholarship

Epigenetic mechanisms regulating expression of the glucocorticoid receptor gene (NR3C1) promoter may influence behavioral and biological aspects of stress response in human infants. Acoustic features of infant crying are an indicator of neurobehavioral and neurological status not yet investigated in relation to epigenetic mechanisms. We examined NR3C1 methylation in placental tissue from a series of 120 healthy newborn infants in relation to a detailed set of acoustic features extracted from newborn infant cries. We identified significant associations of NR3C1 methylation with energy variation in infants' cries as well as with the presence of very high fundamental frequency in …
