Brain Mapping Of The Latency Epochs In A Mcgurk Effect Paradigm In Music Performance And Visual Arts Majors, Lauren Donelle Nordstrom

Theses and Dissertations

The McGurk effect is an illusion that occurs when an auditory /ba/ is combined with a visual /ga/. The two stimuli fuse together which leads to the perception of /da/, a sound in between /ba/ and /ga/. The purpose of this study was to determine whether music performance and visual arts majors process mismatched auditory and visual stimuli, like the McGurk effect, differently. Nine syllable pairs were presented to 10 native English speakers (5 music performance majors and 5 visual arts majors between the ages of 18 and 28 years) in a four-forced-choice response paradigm. Data from event-related potentials were …

Rab Proteins And Alzheimer's: A Current Review Of Their Involvement In Amyloid Beta Generation With Focus On Rab10 Expression In N2a-695 Cells, Ivan Arano Rodriguez

Theses and Dissertations

This thesis work describes the role of Rab proteins in amyloid processing and clearance in different cell pathways. It also describes an experimental approach used to analyze the expression effects of Rab10 in amyloid beta production. Since the main theory behind neurodegeneration in Alzheimer's disease claims that high levels of amyloid beta 42 (Aβ42) molecules trigger widespread neuronal death, control of Aβ42 has been a main target in Alzheimer's disease research. In addition, several studies show increased levels of particular Rab proteins in Alzheimer's pathogenesis. However, no review consolidates current findings in neurodegeneration of Alzheimer's with Rab protein dysfunction. The …

Shakespeare's Art And Artifice: Passing For Real In As You Like It, Kristen Nicole Cardon

Theses and Dissertations

Gender performativity, detailed by Judith Butler and accepted by most contemporary queer theorists, rests on an agentive model of gender wherein “genders are appropriated, theatricalized, worn, and done” (“Imitation and Gender Insubordination” 716). This academic orthodoxy is challenged, however, by the increasing presence of transgender persons joining the theoretical discourse, many of whom experience an essential gender as a central facet of their identity. I respond to Katie R. Horowitz’s recent modification of Butler’s theories—a theory of omniperformance to dissolve the distinction between performance and performativity, and thereby between artifice and “real life.” I argue that gender-as-art, a schema that …

External Validity Of Grammatical Word Category Classification Using An Adaptation And Selection Model, Michelle Chatterton

Theses and Dissertations

The process of acquiring language requires children to learn grammatical categories and apply these categories to new words. Researchers have proposed various explanations of this process in the form of algorithms and computational modeling. Recently, adaptation and selection models have been tested and applied as a possible explanation to the process of acquiring grammatical categories. These studies have proven promising, however, the external validity of this approach has not been examined by grammatically coding samples outside the training corpus. The current thesis applies an adaptation and selection model, which pauses the evolution of dictionaries after every thousand cycles to allow …

Betende Hande: Albrecht Durer's Self-Portrait As A Gothic Church, Christine Heathcote

Theses and Dissertations

In 1508 Albrecht Dürer, famed German printmaker and Nürnberg citizen, was commission by Jakob Heller of Frankfurt to paint a large altarpiece for a new church. The Heller Altarpiece was the second commission of the printer since his training in Venice, Italy (1504-1507) to paint like an Italian master. In order to prepare for such a commission, Dürer spent over a year creating drawings of black ink and white chalk on blue Venetian paper to serve as inspiration for the large painting. However once the painting was complete, the artist held onto these ink and chalk drawings as part of …

The Biology Of Claudin 6 (Cldn6) In The Developing Mouse Lung, Felix Ruben Jimenez Rondan

Theses and Dissertations

The tight junctions (TJ), which are located in the apical region between epithelial and endothelial cells, regulate the paracellular diffusion of ions and small molecules and play an important role in maintaining cell polarity, cell-cell integrity, and permeability. In the lung, epithelial cells are attached by TJ structures. They provide a permeable barrier and cell communication. The loss of barrier integrity, which is maintained by the expression of claudins (Cldn), results in cellular permibilization and leads to paracellular diffusion of solutes and harmful molecules. There are 27 known Cldn homologous members in mice and human. Cldn6 is mostly expressed in …

The Role Of Receptors For Advanced Glycation End-Products (Rage) And Ceramide In Cardiovascular Disease, Michael Bruce Nelson

Theses and Dissertations

Type 2 diabetes and cigarette smoke exposure are associated with an increased risk of cardiovascular complications. The role of advanced glycation end-products (AGEs) is already well-established in numerous comorbidities including cardiomyopathy. Given the role of AGEs and their receptor, RAGE, in activating inflammatory pathways, we sought to determine whether ceramides could be a mediator of RAGE-induced altered heart mitochondrial function. Using an in vitro model, we treated H9C2 cardiomyocytes with carboxy-methyl lysine-BSA, followed by mitochondrial respiration assessment. We found that mitochondrial respiration was significantly impaired in AGE-treated cells, but not when co-treated with myriocin, an inhibitor of de novo …

A Diachronic Analysis Of North And South Korean Monophthongs: Vowel Shifts On The Korean Peninsula, Jessica M. Morgan

Theses and Dissertations

The linguistic situation on the Korean peninsula is one ripe for research. For the past 70 years the two halves of the peninsula have been isolated from one another, thus creating two very different environments for development and change within the Korean language. It is hypothesized that due to conflict, divide, and social turmoil on the peninsula, the Korean language will have undergone a period of change in the last 70 years. This particular investigation looks at North and South Korean monophthong systems for evidence of a phonological shift. Studies of North Korea's language planning (Yong, 2001; Kumatani, 1990) will …

Modeling Children's Acquisition Of Grammatical Word Categories From Adult Input Using An Adaptation And Selection Algorithm, Nicole Adele Stenquist

Theses and Dissertations

It is understood that children learn the use of grammatical categories in their native language, and previous models have only been partially successful in describing this acquisition. The present study uses an adaptation selection algorithm to continue the work in addressing this question. The input for the computer model is child-directed speech towards three children, ages ranging from 1;1 to 5;1 during the course of sampling. The output of the model consists of the input words labeled with a grammatical category. This output data was evaluated at regular intervals through its ability to correctly identify the grammatical categories of language …

The Cascading Effects Of Invasive Grasses In North American Deserts: The Interactions Of Fire, Plants, And Small Mammals, Tiffanny R. Bowman

Theses and Dissertations

The landscapes of the Great Basin and Mojave Deserts are changing due to plant invasion. Highly flammable invasive grasses increase the size and frequency of fire causing a cascade of effects through the plant and animal communities. One of the most influential animal groups in desert systems is small mammals. We sought to learn how small mammals are impacted by fire and how their influence on the plant community differs between burned and unburned habitat. Small mammals did not have higher rates of mortality as a direct result of a controlled burn. In the Great Basin, there were short-term reductions …

A Mathematical Model Of Amoeboid Cell Motion As A Continuous-Time Markov Process, Lynnae Despain

Theses and Dissertations

Understanding cell motion facilitates the understanding of many biological processes such as wound healing and cancer growth. Constructing mathematical models that replicate amoeboid cell motion can help us understand and make predictions about real-world cell movement. We review a force-based model of cell motion that considers a cell as a nucleus and several adhesion sites connected to the nucleus by springs. In this model, the cell moves as the adhesion sites attach to and detach from a substrate. This model is then reformulated as a random process that tracks the attachment characteristic (attached or detached) of each adhesion site, the …

Optimization Of Nonadsorptive Polymerized Polyethylene Glycol Diacrylate As A Material For Microfluidics And Sensor Integration, Chad Rogers

Theses and Dissertations

Microfluidics is a continually growing field covering a wide range of applications, such as cellular analysis, biomarker quantification, and drug discovery; but in spite of this, the field of microfluidics remains predominately academic. New materials are pivotal in providing tailored properties to improve device integration and decrease prototype turnaround times. In biosensing, nonspecific adsorption in microfluidic systems can deplete target molecules in solution and prevent analytes, especially those at low concentrations, from reaching the detector. Polyethylene glycol diacrylate (PEGDA) mixed with photoinitiator forms, on exposure to ultraviolet (UV) radiation, a polymer with inherent resistance to nonspecific adsorption. Optimization of the …

The SRILM is a toolkit for building and applying statistical language models (LMs), designed and developed primarily for use in speech recognition, statistical tagging and segmentation, and machine translation. It has been under development in the SRI Speech Technology and Research Laboratory since 1995. The toolkit has also greatly benefited from its use and enhancements during the Johns Hopkins University/CLSP summer workshops in 1995, 1996, 1997, and 2002. In this thesis, the effect of smoothing and order of N-gram for language model we build by srilm toolkit is studied. My primary method is to use comparison. Firstly, training corpus and …

Spiders Or Butterflies? Despite Student Preference, Gender-Biased Lesson Models Do Not Impact Interest, Attitude, And Learning In Biology, Amy N. Buxton

Theses and Dissertations

Educational research often emphasizes the prevalent gender gap between males and females in science, technology, engineering, and mathematics (STEM) fields. While many studies have found a gender bias when it comes to specific areas of science, little has been done to analyze the effects of how we teach within each of these subjects. In our study, we took a new angle on gender research by specifically considering whether there is a gender gap in how the models (the specific lesson examples/content used to teach a broader biology topic) used to teach biology affect student interest, attitude, and learning. We first …

Latitudinal Variation In Lifetime Survival And Reproduction In A Burying Beetle, Clinton T. Laidlaw

Theses and Dissertations

Temperature variation experienced across a latitudinal range is tied to changes in lifespan and life history across multiple taxa. Two patterns of adaptation to latitudinal temperature variation have been documented – counter-gradient (or co-gradient) variation, and local adaptation. To determine how natural selection has shaped life history variation in a burying beetle, Nicrophorus orbicollis, we quantified lifetime patterns of reproduction in two populations that represent the geographic and temperature extremes occupied by the species. Lifetime reproduction was quantified at two temperatures that represented conditions typical for each population. Burying beetles from different extremes of their geographic range show considerable variation …

The Chosen One: A Q-Method Analysis Of The “€œHarry Potter”€ Phenomenon, Cindy Phippen

Theses and Dissertations

This study examines how pop culture fandoms are formed, based on five communications theories: Escapism, Mood Management, Parasocial Relationships, Identification, and Social Capital. The researcher examined the Harry Potter fandom specifically because of its global pervasiveness. Using Q Methodology, 47 respondents fell into one of four categories: Relationship Experts, Happy Introverts, Identifying Isolationists, and Isolated Self-regulators. Relationship Experts like Harry Potter because of parasocial relationships with the characters as well as the story's capacity for escapism, and Happy Introverts focus on liking Harry Potter for their own enjoyment (not that of others) and mood management. Identifying Isolationists like Harry Potter …

Monophthongal Vowel Production In Females With Primary Sjögren's Syndrome Following A Hydration Treatment Of Nebulized Saline, Kara Rytting

Theses and Dissertations

Sjögren's Syndrome (SS) is an autoimmune disease that causes extreme dryness, or sicca,of the eyes and mouth, as well as other potential drying of the throat and intestines. Speech, voice, and swallowing problems are common in individuals with SS. Therefore, this study examined the possible changes in acoustic characteristics of monophthongs (/i, æ, α, u, ʌ/) in eight females with SS following laryngeal hydration treatments. An ABAB experimental design was implemented. Treatment consisted of nebulized isotonic saline immediately following completion of audio-recordings. Using acoustic analysis software the duration, formant frequencies, and vowel space area (VSA) was calculated for the participant's …

Judicious Use Of Communication For Inherently Parallel Optimization, Andrew W. Mcnabb

Theses and Dissertations

Function optimization---finding the minimum or maximum of a given function---is an extremely challenging problem with applications in physics, economics, machine learning, engineering, and many other fields. While optimization is an active area of research, only a portion of this work acknowledges parallel computation, which is now widely available. Today, anyone with a modest budget can buy a cluster with hundreds of cores, pay for access to a supercomputer with thousands of processors, or at least purchase a laptop with 8 cores. Thus, an algorithm that works well in serial but cannot be parallelized is needlessly inefficient in real-life computationalenvironments.We address …

Interactions Between Race, Gender, And Income In Relationship Education Outcomes, Andrew K. Thompson

Theses and Dissertations

Researchers and policymakers have become interested in the use of relationship education programs as a means to remedy the effects of family instability. Research suggests that relationship education produces positive outcomes with some groups. However, whether populations who are socially and economically more at-risk of relationship problems and relationship dissolution are gaining from relationship education remains an open question. Ecocultural Theory is used to conceptualize the research question and to illustrate the importance of studying diverse populations. The purpose of this study is to assess relationship education outcomes for select at-risk groups. The sample for this study (n=1,907) comes from …

Stoichiometric Controls On Denitrification In High Nitrate Watersheds, Brian Grebliunas

Theses and Dissertations

Watershed biogeochemistry throughout Midwestern agroecosystems have been altered through hydrologic manipulation and over-application of nitrogenous fertilizers. As a result, nitrate (NO3-N) export from subsurface drainage has negative impacts on local and downstream ecosystem health. Wetland installation has proven to be a viable option for targeted management where a large proportion of NO3-N is removed through the bacterially mediated process denitrification. For denitrification to maintain high rates under prolonged NO3-N saturation, a stable supply of labile dissolved organic carbon (DOC) is required. The focus of this dissertation was to study how the stoichiometry of agricultural wetlands limits denitrification within a controlled …

Subsistence Strategies In The Upper Illinois River Valley: The Kuhne Site Case Study, Autumn Beyer

Theses and Dissertations

Stuart Struever's excavation of the Kuhne site, located in the Upper Illinois River Valley occurred during the start of archaeological interest in the region. The faunal remains recovered during this excavation offer a unique opportunity to understand subsistence strategies in the area during the Middle Woodland period. Using standard zooarchaeological methods, these remains were analyzed to better understand which animal species were targeted by Middle Woodland people in this region, which season(s) the site was occupied, and how bones were modified for utilitarian and other purposes. These findings were then compared to faunal assemblages from Middle Woodland sites in the …

G-Quadruplex Dna Structures And Site Specific Genetic Instability, Jonathan David Williams

Theses and Dissertations

Repetitive DNA comprises a majority of the human genome yet functions and overall impacts on site-specific genetic instability are not fully defined. Repetitive G-rich sequences have the propensity to form G-quadruplex (G4), which are stable non-B form DNA structures. G4 structures are conspicuously found at regions of site-specific instability. Even so, human genomic loci capable of forming this structure and their connection to DNA rearrangements are just beginning to be elucidated. My dissertation focuses on G4 structures and their capacity to promote site-specific changes in the human genome, particularly at oncogenes. I identified and investigated new biologically relevant G4 loci …

ILLINOIS TEACHER EVALUATION STUDENT GROWTH COMPONENT:

A PREDECISION-MAKING POLICY ANALYSIS

Joshua R. Olsen

122 Pages May 2015

Public school districts in Illinois are going to face massive changes to their evaluation systems in the coming years. Thanks to the adoption of the Performance Evaluation Reform Act of 2010 and Senate Bill 7 of 2011, teacher evaluation must contain student growth as a significant factor, beginning with the 2016-2017 school year. Not only must student performance on tests become part of the evaluation of teachers, but, moreover, teacher evaluation will play a greater role in the hiring, retention, and release of …

Functional Expression And Characterization Of A Truncated Candida Antarctica Lipase B In Yeast, Samantha Robinson

Theses and Dissertations

Candida antarctica lipase B is an enzyme capable of hydrolyzing ester bonds in a lipid-water interface with potential to become a useful biocatalyst for production of biodiesel fuel. Enzymatically catalyzing the transesterification of triacylglycerides to produce fatty acid alkyl esters (biodiesel) is an environmentally cleaner alternative to the current process which utilizes chemical reagents as catalysts. Optimization and development of strains to express highly active, stable, large quantities of these biocatalysts is essential for inexpensive production of biodiesel. Additionally, lipase enzymes can be immobilized onto a resin, eliminating the need to recover the catalyst from the product and allowing multiple …

Nurturing Young Learners In Practice: A Case Study Of Key Teacher Dispositions That Support Child Centered Practice In An Urban Preschool Environment, Lorraine Ricchezza

Theses and Dissertations

This dissertation examines an educator's disposition to positively impact children's cognitive and social emotional development in the preschool setting as evidenced in child centered practices that arouse curiosity, foster social interaction, and promote children's learning as expressed in interpersonal interactions that affirm differences among young children in an urban preschool setting. Through examination and interpretation, this study delineates educator perspectives on child differences and reciprocal relationships as integral to developmentally appropriate practice. Seven female educators at the ABC Elementary School in Urban City, New Jersey participated in this study. This study involved key data sources. During 8 months of data …

Student Criminality: The Influence Of Strain, Family And Peers, Annie Cvetan

Theses and Dissertations

General strain theory suggests that a number of conditioning factors affect who is more likely to respond to strain with crime. Research has also demonstrated that an individual's self-complexity plays a role in how an individual responds to strain. Self-complexity refers to (1) the number of identities individuals perceive as important to themselves; and (2) the varied characteristics they ascribe to these identities. This research study analyzed if college students were committing crime, whether the crimes were major or minor in nature, and if criminality was a new behavior or an imported one. This study also looked at who, if …

Validity Of Holocene Analogs For Ancient Carbonate Stratigraphic Successions: Insights From A Heterogeneous Pleistocene Carbonate Platform Deposit, Colby Hazard

Theses and Dissertations

Observations of modern carbonate depositional environments and their accompanying depositional models have been used for decades in the reconstruction and interpretation of ancient carbonate depositional environments and stratigraphic successions. While these Holocene models are necessary for interpreting their more ancient counterparts, they inherently exclude important factors related to the erosion, diagenesis, and ultimate preservation of sediments and sedimentary structures that are ubiquitous in shallow marine carbonate environments. Andros Island, Bahamas is an ideal location to examine the validity of Holocene conceptual models, where geologically young (Late Pleistocene) limestones can be studied immediately adjacent to their well-documented modern equivalents. For this …
