A Hypermedia Design For Both High And Low Knowledge Readers, Jonathan Vickers

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this case study is to examine possibilities for improving upon hypermedia design in regards to readers and their varied levels of prior knowledge. By creating a hypermedia website that looks at the development of rock climbing at Coopers Rock State Forest, I will explore the possibility of using prompts intended to help prepare readers with low levels of subject (rock climbing) knowledge to understand and make sense of the content. However, at the same time, it is important to allow readers with high levels of subject knowledge to bypass these prompts because of their ability to limit …

Structural Elucidation Of Glycerophospholipids Using Metastable Atom-Activated Dissociation Mass Spectrometry (Mad-Ms), Robert E. Deimler

Graduate Theses, Dissertations, and Problem Reports (ETD)

Recent developments in analytical instrumentation have allowed scientists to investigate systems that were unattainable in the past. In the biomedical community this increase in investigative power has allowed the exploration of biological components like proteins, lipids, and DNA and their role in the many different cycles necessary for human life. By understanding the nuances of these processes, medical professionals can more easily recognize the products of mutations or malfunctions that can lead to more accurate prognosis and diagnosis of disease. Typically, lipids are analyzed through hyphenated chromatography-mass spectrometry instruments and especially using collision-induced dissociation (CID). Low-energy CID typically produces both …

Volumetric, Planar And Linear Airway Comparison After Maxillomandibular Advancement Surgery, Deepa Vyas

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background and Objectives: Treatment of sleep apnea can be accomplished using both non-surgical and surgical methods. Surgical treatment is further classified into phase I and II surgery. When phase I treatment fails, orthognathic surgery is judged to be the subsequent step in treating these patients. Orthognathic surgery is considered phase II treatment and can consist of a maxillomandibular advancement (MMA)1-11. Until recently, most of the data gathered on patients how have had a maxillomandibular advancement has been completed using lateral cephalograms. The rationale for this study is to gain a better understanding of the alteration in linear, planar and volumetric …

Cbct Evaluation Of Condylar Changes In Children With Unilateral Posterior Crossbites With A Functional Shift, Lance Pittman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: The unilateral posterior crossbite with a functional shift is one of the most common early adolescent malocclusions. It is caused by a transversely deficient maxilla, relative to the mandible, and results when the mandible shifts to one side to so the teeth can maximally interdigitate. This shift is thought to cause the contralateral condyle to move anteriorly, inferiorly, and medially within the TMJ. Much attention has been given recently to the affects of this functional shift on the condyles. An attempt is being made to determine if pathological position of the condyles can cause condylar signs or symptoms similar …

Vibration Attenuation Of Composite Moving Beams Using Active Vibration Control Techniques, Gouthami Polina

Graduate Theses, Dissertations, and Problem Reports (ETD)

Applications of axially-moving beams are found in earthquake engineering, robotic arms, conveyor belts, etc. Previous studies have shown that the amplitude of lateral vibration of moving beams is 40 percent higher than that of non moving beams. In this research a numerical model based on the finite element method is done to reduce the excess vibrations caused by the axial oscillation of the beam. A computer code is written in MATLAB to accomplish this.;The vibrational amplitude of composite moving beams is reduced by means of an active vibration control technique that employs the piezoelectric effect. Piezoelectric sensors and actuators are …

Assuming Identities: Gender, Sexuality, And Performativity In The Silence Of The Lambs, Lynne Stahl

Faculty & Staff Scholarship

In the introduction to Epistemology of the Closet, Eve Kosofsky Sedgwick discusses the instability of the ignorance/knowledge binary, which generally equates the latter with power and the former with impotence. She argues that ignorance (or the appearance thereof) can be a tool of power as well, citing as an example the 1986 ruling by the United States Justice Department that employers “may freely fire persons with AIDS” provided that those employers “can claim to be ignorant of the medical fact, quoted in the ruling, that there is no known health danger in the workplace from the disease” (5). That this …

Female Brain Drains And Women’S Rights Gaps: A Gravity Model Analysis Of Bilateral Migration Flows, Maryan Naghsh Nejad, Andrew T. Young

Economics Faculty Working Papers Series

In this paper we model the migration decisions of high-skilled women as a function of the benefits associated with moving from an origin with relatively low women´s rights to a destination with a relatively high women´s rights. However, the costs faced by women are decreasing in the level of women´s rights provided. The model predicts a non-linear relationship between the relative levels of women’s rights in destination versus origin countries (the women’s rights gap) and the gender gap in high-skilled migration flows (the female brain drain ratio). In particular, starting from large values of the women´s rights gap (where women´s …

A Spatial Analysis Of Incomes And Institutional Quality: Evidence From Us Metropolitan Areas, Jamie Bologna, Donald J. Lacombe, Andrew T. Young

Economics Faculty Working Papers Series

We use the Stansel (2013) metropolitan area economic freedom index and 25 conditioning variables to analyze the spatial relationships between institutional quality and economic outcomes across 381 U.S. metropolitan areas. Specifically, we allow for spatial dependence in both the dependent and independent variables and estimate how economic freedom impacts both per-capita income growth and per-capita income levels. We find that while economic freedom and income levels are directly and positively related, increases in economic freedom in one area result in negative indirect effects on income levels in surrounding areas. In addition, we find that economic freedom has an insignificant relationship …

Dawn–Dusk Asymmetries In The Coupled Solar Wind–Magnetosphere–Ionosphere System: A Review, A. P. Walsh, S. Haaland, C. Forsyth, A. M. Keesee

Faculty & Staff Scholarship

Dawn–dusk asymmetries are ubiquitous features of the coupled solar-wind–magnetosphere–ionosphere system. During the last decades, increasing availability of satellite and ground-based measurements has made it possible to study these phenomena in more detail. Numerous publications have documented the existence of persistent asymmetries in processes, properties and topology of plasma structures in various regions of geospace. In this paper, we present a review of our present knowledge of some of the most pronounced dawn–dusk asymmetries. We focus on four key aspects: (1) the role of external influences such as the solar wind and its interaction with the Earth's magnetosphere; (2) properties of …

Investigating The Lay And Scientific Norms For Using ‘Explanation’, Jonathan Waskan, Ian Harmon, Andrew Higgins, Joseph Spino

Faculty & Staff Scholarship

In the mid-twentieth century, Hempel (1962, 1965) bucked posit ivist ort hodoxy and proposed that explanations have a legitimate role to play in science. Yet, when it came time to offer up a model of explanation, Hempel held fast to the positivist tendency of abstracting both from facts about human psychology and from the specific contents of claims (i.e., in favor of bare logical form). At the broadest level, he proposed that explanations are sets of true statements arranged into formally acceptable arguments. That such arguments count as explanations has, Hempel thought, nothing to do with what anyone thinks or …

Altering Endoplasmic Reticulum Stress In A Model Of Blast-Induced Traumatic Brain Injury Controls Cellular Fate And Ameliorates Neuropsychiatric Symptoms, Aric F. Logdson, Ryan C. Turner, Brandon P. Lucke-Wold, Matthew J. Robson, Zachary J. Naser, Kelly E. Smith, Rae R. Matsumoto, Jason Delwyn, Charles L. Rosen

Faculty & Staff Scholarship

Neuronal injury following blast-induced traumatic brain injury (bTBI) increases the risk for neuropsychiatric disorders, yet the pathophysiology remains poorly understood. Blood-brain-barrier (BBB) disruption, endoplasmic reticulum (ER) stress, and apoptosis have all been implicated in bTBI. Microvessel compromise is a primary effect of bTBI and is postulated to cause subcellular secondary effects such as ER stress. What remains unclear is how these secondary effects progress to personality disorders in humans exposed to head trauma. To investigate this we exposed male rats to a clinically relevant bTBI model we have recently developed. The study examined initial BBB disruption using Evan’s blue (EB), …

Recognizing Age-Separated Face Images: Humans And Machines, Daksha Yadav, Richa Singh, Mayank Vatsa, Afzel Noore

Faculty & Staff Scholarship

Humans utilize facial appearance, gender, expression, aging pattern, and other ancillary information to recognize individuals. It is interesting to observe how humans perceive facial age. Analyzing these properties can help in understanding the phenomenon of facial aging and incorporating the findings can help in designing effective algorithms. Such a study has two components - facial age estimation and age-separated face recognition. Age estimation involves predicting the age of an individual given his/her facial image. On the other hand, age-separated face recognition consists of recognizing an individual given his/her age-separated images. In this research, we investigate which facial cues are utilized …

Schizophrenia (SCZ) is a severe, debilitating mental illness which has a significant genetic component. The identification of genetic factors related to SCZ has been challenging and these factors remain largely unknown. To evaluate the contribution of de novo variants (DNVs) to SCZ, we sequenced the exomes of 53 individuals with sporadic SCZ and of their non-affected parents. We identified 49 DNVs, 18 of which were predicted to alter gene function, including 13 damaging missense mutations, 2 conserved splice site mutations, 2 nonsense mutations, and 1 frameshift deletion. The average number of exonic DNV per proband was 0.88, which corresponds to …

Galvanic Manufacturing In The Cities Of Russia: Potential Source Of Ambient Nanoparticles, Kirill S. Golokhvast, Anna A. Shvedova

Faculty & Staff Scholarship

Galvanic manufacturing is widely employed and can be found in nearly every average city in Russia. The release and accumulation of different metals (Me), depending on the technology used can be found in the vicinities of galvanic plants. Under the environmental protection act in Russia, the regulations for galvanic manufacturing do not include the regulations and safety standards for ambient ultrafine and nanosized particulate matter (PM). To assess whether Me nanoparticles (NP) are among environmental pollutants caused by galvanic manufacturing, the level of Me NP were tested in urban snow samples collected around galvanic enterprises in two cities. Employing transmission …

Automated Assessment Of Upper Extremity Movement Impairment Due To Stroke, Erienne V. Olesh, Sergiy Yakovenko, Valeriya Gritsenko

Faculty & Staff Scholarship

Current diagnosis and treatment of movement impairment post-stroke is based on the subjective assessment of select movements by a trained clinical specialist. However, modern low-cost motion capture technology allows for the development of automated quantitative assessment of motor impairment. Such outcome measures are crucial for advancing post-stroke treatment methods. We sought to develop an automated method of measuring the quality of movement in clinically-relevant terms from low-cost motion capture. Unconstrained movements of upper extremity were performed by people with chronic hemiparesis and recorded by standard and low-cost motion capture systems. Quantitative scores derived from motion capture were compared to qualitative …

Fr-Captcha: Captcha Based On Recognizing Human Faces, Gaurav Goswami, Brian M. Powell, Mayank Vatsa, Richa Singh, Afzel Noore

Faculty & Staff Scholarship

A Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) is designed to distinguish humans from machines. Most of the existing tests require reading distorted text embedded in a background image. However, many existing CAPTCHAs are either too difficult for humans due to excessive distortions or are trivial for automated algorithms to solve. These CAPTCHAs also suffer from inherent language as well as alphabet dependencies and are not equally convenient for people of different demographics. Therefore, there is a need to devise other Turing tests which can mitigate these challenges. One such test is matching two faces …
