Co -Localization Of D 1 And Darpp-32 In Methamphetamine-Treated Rat Nucleus Accumbens, Perirhinal Cortex, And Hippocampus, Yonca Cam

Theses and Dissertations

Methamphetamine abuse is a major health concern that has been associated with adverseeffects such as behavioral disturbances, impaired memory, and cognitive deficits. Chronic use of methamphetamine has been found to cause persistent changes in dopamine receptors and DARPP-32 expression in the rat striatum. Because methamphetamine use has been associated with memory and cognitive impairments, chronic effects in memory-related regions should be thoroughly examined as well. The current study investigated the long-term effects of methamphetamine self-administration on D1 receptor and DARPP-32 expression on the subregions of nucleus accumbens, hippocampus, and perirhinal cortex via immunostaining. I expected to find decreased levels of …

Scouting Knots Are Not The Same Knots When Knotted, Andres Sanchez

Theses and Dissertations

Knots are used everyday by all people, mathematicians and non-mathematicians alike. There are certain subsets of people that use knots more frequently than others such as sailors or members of the Scouting Movement.

A mathematical knot is a subset of 3-space that is homeomorphic to the unit circle. A knot used in non-mathematical circles is generally considered when two strings, etc. are wrapped around each other, with the ends potentially hanging. We introduce and explain through examples 1) how mathematical knots differ from general knots; 2) how mathematical knots differ from other mathematical knots via methods of deformation, colorability, and …

Let's Talk! An Investigation Of Parent-Child Conversations About Self-Conscious Emotions, Alexandra Marie Cooper

Theses and Dissertations

Parents play an important role in socializing children's emotion understanding. Previous research on parents' conversations with their children shows that parents emphasize different aspects of emotion contexts depending on the emotion depicted. However, there is limited research on how parents and children discuss self-conscious emotions, such as embarrassment, guilt, and shame. The current study explored the socialization of self-conscious emotions in parent-child conversations during a storybook task. One hundred and sixty-six children between the ages of 24 and 36 months were observed reading a storybook with their parent. Analyses of parent-child conversations revealed that while parent and child utterances were …

The Value Of An Anthropology Degree: Why Undergraduates Major In Anthropology And How It Prepares Them For Life After College, Maria Kitchin

Theses and Dissertations

“What are you gonna do with that degree?” is a question frequently asked of anthropology majors. This question implies that the value of a college degree is only about getting a job and that the field of anthropology is not useful to that end. In fact, the popularity of anthropology and related liberal arts fields has been declining even as the number of students enrolled at universities has steadily increased. In a moment when the value of a liberal arts degree is questioned in public discourse, I explore the motivations and goals of students who have chosen to study anthropology …

Effects Of Exercise Intensity And Type On Executive Function In Elementary-Aged Children, Patrick Pommier

Theses and Dissertations

The interactions of exercise on executive functioning (EF) have been studied thoroughly in previous literature, focusing mostly on the interactions of aerobic exercise (AE) intensity and its effects on inhibition and working memory. Although multiple categories of EF have been shown to improve based on aerobic exercise, the foundation of brain development relies within its ability to utilize all three areas of EF simultaneously. Therefore, the purpose of this study was to determine the effects of exercise intensity and type of exercise (cognitive activation) on EF in elementary-aged children. Design: Eighteen children (mean age=10.4, SD=0.5, 61.1% girls) participated in a …

To Control Or Be Controlled: Sibling Control And Adolescent Sibling Relationship Quality, Lauren Elizabeth Andrus

Theses and Dissertations

The current body of research pertaining to sibling control dynamics look specifically at either the absence or presence of control within the sibling relationship. Research to date has not differentiated between a sibling's experience of being controlling versus being controlled. This study examined adolescent sibling control dynamics and its link with sibling relationship quality (sibling closeness and sibling conflict), and how those links are moderated by birth order and having an agreeable personality. Data were analyzed from 327 families with two adolescent siblings between the ages of 12 and 18 (Older Sibling M = 17.17 years, SD = .94; Younger …

A Computational Investigation Of The Biophysical Mechanisms Underlying Thermotaxis In The Afd Neurons Of Caenorhabditis Elegans, Zachary Mobille

Theses and Dissertations

Thermotaxis in the nematode Caenorhabditis elegans (C. elegans) is studied at the cellular scale of the amphid finger-like ciliated (AFD) neurons, which have previously been shown to be essential for thermoreception. The voltage and calcium signals of AFD during temperature stimuli are described with ordinary differential equations. The primary calcium model is a modified version of that published by Kuramochi and Doi in 2017 to explain the calcium responses of the chemosensitive amphid single-ciliated right (ASER) neuron to fluctuations in extracellular salt concentration. To account for the effects of temperature, changes to the stimuli conditions under which inactivation takes place …

Rethinking The Refugee Regime: Would A Human Rights-Based Approach To The Issue Of Climate Refugees Produce Just Outcomes?, Gordon Robinson

Theses and Dissertations

Human rights-based approaches are highly useful for a myriad of issues facing the international community. However, they have yet to be utilized in practice due to norms in the international community that favor sovereignty over human rights and international cooperation. This thesis will demonstrate the utility of such approaches by applying one to the issue of climate refugees. It is estimated that by the year 2050, hundreds of millions of people around the globe will become displaced due to climate change. Because climate-related reasons are not included in the criteria for what makes one a refugee, these people will not …

Engineering Cell-Free Protein Expression Systems For Biotherapeutics And Biosensing, John Porter Hunt

Theses and Dissertations

Therapeutic proteins have become a cornerstone of modern medicine since the FDA approval of recombinant human insulin in 1982. Likewise, biosensors transform chemical detection and disease diagnostics by identifying biomarkers, chemical contaminants, and infective agents. Long-standing methods for creating therapeutics and biosensors employ whole cells such as Escherichia coli (E. coli). Alternatively, cell-free protein synthesis (CFPS) employs the enzymatic reactions necessary for protein production and biosensing within a cell, but in an engineered reactor environment facilitating unprecedented access to and control over biochemical machinery, preservation by cryodesiccation for portable deployment, and functionality in cytotoxic applications. This dissertation reports advances in …

Theses and Dissertations

The overall goal of this thesis was to genetically improve agronomic traits of pennycress (Thlaspi arvense L.; Field Pennycress) and demonstrate the production of value-added designer seed oils to domesticate pennycress and enable its establishment as a new winter annual oilseed/meal/cover crop to be grown in temperate regions of the world. In the U.S. Midwest, pennycress can be double cropped on existing farmland during the time between corn harvest and subsequent planting of soybeans the following spring. Pennycress has the potential to produce 2,000 lbs/acre seeds, which at 33% by weight oil content and 20% protein, would yield 85 gallons/acre …

“Natural Ties For Patriotic Purposes": The Committee On Public Information, Americanization, And Swedish-American Transnationalism, Race L. Fisher

Theses and Dissertations

The Committee on Public Information (CPI) was the official propaganda agency of the United States during the First World War, seeking to homogenize American public opinion and spread American ideals across the globe. Through a case study of Edwin Björkman’s work among Swedish Americans, this thesis illuminates how the CPI approached its work among immigrants, engaging questions of Americanization and transnationalism. Through an analysis of the John Ericsson League of Patriotic Service and the Scandinavian Bureau—both its domestic and foreign operations—this thesis argues that Edwin Björkman and the CPI promoted cultural pluralism rather than assimilation to a dominant Anglo-American culture. …

Material Witnesses: Deconstructing Networks Of Credibility And Objectivity In Medical Narratives From Mary Toft To The Contraceptive Pill, Krista Elizabeth Roberts

Theses and Dissertations

In this dissertation, I argue that to better understand the tangled, embedded human and nonhuman subjects and how their testimonies function in western medical history, we need to first understand their erasure. By using relationality as a reading method, I break apart who and with whom individuals make medical decisions by considering what constitutes evidence. In the Mary Toft case, expert witnessing informs the ways in which a reader trusts what the narrator claims. The medicolegal conventions of courtroom testimony shape the ways in which medical men wrote their pamphlets. These men shore up their credibility through descriptions of nonhuman …

Evaluating The Multi-Level Community Effects Of Root Hemiparasites In Northern Illinois, Anna Marie Scheidel

Theses and Dissertations

Root hemiparasites are green plants that tap into a neighboring plant’s water-filled xylem to acquire inorganic nutrients, which can lead to an accumulation of nutrients in hemiparasite biomass. I performed an observational field study at Nachusa Grasslands and Franklin Creek State Natural Area (Lee County, IL) in 2019 to investigate how the presence of five root hemiparasites (Aureolaria grandiflora (Benth.) Pennell, Agalinis tenuifolia (Vahl) Raf., Castilleja sessiliflora (Pursh), Dasistoma macrophylla (Nutt.) Raf., Pedicularis canadensis L.) affects their communities through the (a)keystone species hypothesis, that hemiparasites will increase measures of diversity by altering competition among surrounding plant species, (b) ecological engineer …

The Politics Of Di/Visibility: Narrative Positioning And Disability Representation In Children’S Literature, Agathe Lancrenon

Theses and Dissertations

Disabled individuals are the largest minority group in the United States and Disability scholarship is intricately connected to lived experiences and advocacy, but it too often remains overlooked even in conversations that intend to bring to light historically underrepresented groups. This dissertation provides an analysis of a broad range of children’s literature and its role in constructing literal and ideological images of disability. It offers a critical analysis of visuality in the following children’s texts: Wonder by R.J. Palacio, El Deafo by Cece Bell, Miss Little’s Gift by Douglas Wood, Thank You, Mr Falker by Patricia Polacco, A Boy and …

Lost In Translation: South Asian Muslim Women's Interpretation Of Religious Gender Role Expectations, Women's Agency, And Women's Identity, Tamanna Tasmin

Theses and Dissertations

This study investigates South Asian Muslim women’s interpretation of religious scripture and the women’s agency to influence the contemporary patriarchal religious culture. Previous research indicates that the religious customs of the region follow traditional orthodox Islamic scripture that promotes patriarchal practices, yielding barriers for women in the family, education, and professional sectors. Based on an understanding of the religious education system, the history of traditional orthodox Islamic practice, and traditional gender role expectations of the region, I use structuration theory to understand South Asian Muslim women’s identity negotiation and the agency they perceive regarding their ability to influence the society. …

Data is explored through the lens of instructional communication, family communication, parent-child relational satisfaction, and parent-child closeness. The present study examined the connections between education and family when learning takes place at home. Findings and recommendations for future research are discussed that explain the relationship between parents and children after homeschooling has ended.

Womanist Ways In A Man's World: Unpacking Anti-Blackness In Higher Education Enrollment Management Roles, Mesha C Garner

Theses and Dissertations

This study evaluated the phenomenon of anti-Black womanism in enrollment management at Historically White Institutions (HWIs) for Black women professionals. The qualitative study was conducted to understand dialectical functions of enrollment management and the dialectical responsibilities that Black women have while working in enrollment management. The theoretical framework of anti-Black womanism guided this study. Anti-Black womanism is a dual lens of BlackCrit (Dei, 2017; Dumas and Ross, 2016) and Womanism (Phillips, 2006). Furthermore, this study comprised the historical perspective and acknowledged the settler-colonial complex to best conceptualize the perceptions of Black people, particularly Black women. This study included 10 participants, …

Personalized Learning Path Generation Based On Genetic Algorithms, Lumbardh Elshani

Theses and Dissertations

A substantial disadvantage of traditional learning is that all students follow the same curriculum sequence, but not all of them have the same background of knowledge, the same preferences, the same learning goals, and the same needs. Traditional teaching resources, such as textbooks, in most cases orient students to follow fixed sequences during the learning process, thus impairing their performance. Curriculum sequencing is an important research issue for learning process because no fixed learning paths will be appropriate for all learners. For this reason, many research papers are focused on the development of mechanisms to offer personalization on learning sequences, …

Re-Aerosolization Of Dense Metal Oxide Simulating Radiological Contamination From Military Clothing, Joseph M. Chapman

Theses and Dissertations

Radiological contamination from nuclear accidents or the terrorist use of a Radiological Dispersal Device (RDD) are events that first responders must be prepared for. It is currently assumed that removal of the victims clothing will remove 80-90 of contamination. Many RDD radioisotopes produce dense aerosols that would then contaminate victim clothing and re-aerosolize during clothing removal. A series of experiments were conducted during which clothing was contaminated with a dense aerosol simulating the radioisotope of Strontium 90. Compared to background, there was statistically significant re-aerosolization from the clothing. This demonstrates inhalation hazards from re-aerosolization of RDD contamination.

Costs And Benefits Of Physical Therapy Program Implementation For Air Force Fighter Pilots, Christian G. Erneston

Theses and Dissertations

Air Force fighter pilots face risks associated with neck and spine injuries sustained while operating fighter aircraft. Studies from the flying and medical communities indicate that muscle-strengthening prehabilitative care may decrease the risk of flying related injuries in high performance aircraft pilots. For this reason, the U.S. Air Force provided $24.9M to implement the Optimizing the Human Weapon System (OHWS) program. The program provides physical therapy and strength training to fighter pilots in participating units at twenty-one Air Force bases with the intent of reducing injury rates and time out of the cockpit. From a healthcare perspective there is interest …

Comparison Of Decision Analysis Methods For A Cubesat Propulsion System, Jared L. Pilcher

Theses and Dissertations

Low Earth Orbit (LEO) is becoming an increasingly congested orbital regime. As a result, propulsion systems on CubeSats are becoming a more desirable feature to provide them with collision avoidance capabilities. To date, there have been very few CubeSat launches with a propulsion system on them. Due to the relatively high cost of a propulsion system compared to the budget of small educational organizations, a decision analysis model is needed so that these organizations can make the best decision between whether to purchase a Commercial-Off-The-Shelf (COTS) product or to develop one within the organization. This research applies three decision analysis …

Satellite Tracking With Neuromorphic Cameras For Space Domain Awareness, Joseph G. Bacon Jr.

Theses and Dissertations

A significant number of objects orbit the space around Earth. Each of these objects, be it debris, a functioning satellite, or even a staffed space station, circle the planet at extreme speeds relative to most objects on the Earth's surface. Any collision would result in disaster thanks to the extreme amount of kinetic energy involved. Space Domain Awareness (SDA) includes the detection, identification, cataloging, and tracking of orbiting objects to prevent such catastrophes. SDA is maintained in multiple ways to include radar, lidar, telescopes, and other sensors. This research investigates the maturing technology of neuromorphic cameras to determine their applicability …

The Impact Of Threat Levels At The Casualty Collection Point On Military Medical Evacuation System Performance, Nathaniel C. Dennie

Theses and Dissertations

One of the primary duties of the Military Health System is to provide effective and efficient medical evacuation (MEDEVAC) to injured battlefield personnel. To accomplish this, military medical planners seek to develop high-quality dispatching policies that dictate how deployed MEDEVAC assets are utilized throughout combat operations. This thesis seeks to determine dispatching policies that improve the performance of the MEDEVAC system. A discounted, infinite-horizon continuous-time Markov decision process (MDP) model is developed to examine the MEDEVAC dispatching problem. The model incorporates problem features that are not considered under the current dispatching policy (e.g., myopic policy), which tasks the closest-available MEDEVAC …

Accelerating Point Set Registration For Automated Aerial Refueling, Ryan M. Raettig

Theses and Dissertations

The goal of AAR is to control the tanker boom to safely refuel a receiving aircraft with no input or aid from the boom operator. To achieve this, the pose of the receiver relative to the tanker must be known. Point set registration is a fundamental issue used to estimate the relative pose of an object in an environment. However, it's likely a computational bottleneck of a vision processing pipeline. In addition, the matching of each sensed point with a closest truth point, nearest neighbor matching, is the most costly portion of the point set registration process. For this reason, …

Correction Of Back Trajectories Utilizing Machine Learning, Britta F. Gjermo Morrison

Theses and Dissertations

The goal of this work was to analyze 24-hour back trajectory performance from a global, low-resolution weather model compared to a high-resolution limited area weather model in particular meteorological regimes, or flow patterns using K-means clustering, an unsupervised machine learning technique. The duration of this study was from 2015-2019 for the contiguous United States (CONUS). Three different machine learning algorithms were tested to study the utility of these methods improving the performance of the CFS relative to the performance of the RAP. The aforementioned machine learning techniques are linear regression, Bayesian ridge regression, and random forest regression. These results mean …

A Comparative Evaluation Of The Fast Optical Pulse Response Of Event-Based Cameras, Tyler J. Brewer

Theses and Dissertations

Event cameras use biologically inspired readout circuit architecture to offer a faster and more efficient method of imaging than traditional frame-based detectors. The asynchronous event reporting circuit timestamps events to 1 microsecond resolution, but latency increases when many pixels are stimulated simultaneously. To characterize this variability, the DAVIS240, DAVIS346, DVXPlorer, and Prophesee Gen3M VGA-CD 1.1 cameras were exposed to single step-function flashes with amplitudes from 9.3-771cd/m², stimulating from 0.0042-100 of pixels. The Median Absolute Deviation of pixel response times ranged between 0 and 6086µs, increasing with the percent of pixels stimulated (PSP). The number of events generated per …

Improving Air Battle Management Target Assignment Processes Via Approximate Dynamic Programming, Joseph M. Liles Iv

Theses and Dissertations

Military air battle managers face many challenges when directing operations in quickly evolving combat scenarios. These scenarios require rapid decisions to engage moving and unpredictable targets. In defensive operations, the success of a sequence of air battle management decisions is reflected by the friendly force's ability to maintain air superiority by defending friendly assets. We develop a Markov decision process (MDP) model of the air battle management (ABM)problem, wherein a set of unmanned combat aerial vehicles (UCAV) is tasked to defend a central asset from cruise missiles that arrive stochastically over time.
