The Strategy Of Metallgesellschaft: A Sophisticated Catallactic Analysis, Janette Goodridge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the fall of 1993, German company Metallgesellschaft, Ag experienced a loss of over one billion dollars. This loss resulted from its hedging strategy, and was one of the largest losses of its kind at the time. Naturally this raised interest regarding what caused these huge losses, and called into question the events and circumstances surrounding and leading up to this disaster. There are two basic schools of thought regarding Metallgesellschaft's strategy. The first is that it was a good strategy and had the potential to be successful and profitable. The other is that its strategy was risky and speculative. …

Misinformation, Fact Checking, And Immigration Voting Preferences, Katherine Van Shaar

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Although misinformation is rampant in social media and society, there is not an extensive literature exploring the impact of misinformation and fact checks on people’s political preferences relating to immigration policies in the US. The purpose of this study is to examine the impacts of misinformation and fact-checking on people’s policy preferences about immigration. Using an experimental survey and a between-subject approach, we observe how anti-immigration politician’s statements (ranging from false to partially true) impact participants’ perceptions of hot-topic immigration issues with and without fact checks. We also study the correlation between people’s political affiliation and the impact of politicians’ …

BACKGROUND: MetaMap is a valuable tool for processing biomedical texts to identify concepts. Although MetaMap is highly configurative, configuration decisions are not straightforward.

OBJECTIVE: To develop a systematic, data-driven methodology for configuring MetaMap for optimal performance.

METHODS: MetaMap, the word2vec model, and the phrase model were used to build a pipeline. For unsupervised training, the phrase and word2vec models used abstracts related to clinical decision support as input. During testing, MetaMap was configured with the default option, one behavior option, and two behavior options. For each configuration, cosine and soft cosine similarity scores between identified entities and gold-standard terms were …

Biotic homogenization—increasing similarity of species composition among ecological communities—has been linked to anthropogenic processes operating over the last century. Fossil evidence, however, suggests that humans have had impacts on ecosystems for millennia. We quantify biotic homogenization of North American mammalian assemblages during the late Pleistocene through Holocene (~30,000 ybp to recent), a timespan encompassing increased evidence of humans on the landscape (~20,000–14,000 ybp). From ~10,000 ybp to recent, assemblages became significantly more homogenous (>100% increase in Jaccard similarity), a pattern that cannot be explained by changes in fossil record sampling. Homogenization was most pronounced among mammals larger than 1 …

Delegation At The Founding: A Response To Critics, Julian Davis Mortenson, Nicholas Bagley

Articles

This essay responds to the wide range of commentary on Delegation at the Founding, published previously in the Columbia Law Review. The critics’ arguments deserve thoughtful consideration and a careful response. We’re happy to supply both. As a matter of eighteenth-century legal and political theory, “rulemaking” could not be neatly described as either legislative or executive based on analysis of its scope, subject, or substantive effect. To the contrary: Depending on the relationships you chose to emphasize, a given act could properly be classified as both legislative (from the perspective of the immediate actor) and also executive (from the perspective …

Identifying Missing Is-A Relations In Orphanet Rare Disease Ontology, Maryamsadat Mohtashamian, Rashmie Abeysinghe, Xubing Hao, Licong Cui

Faculty, Staff and Student Publications

The Orphanet Rare Disease Ontology (ORDO) provides a structured vocabulary encapsulating rare diseases. Downstream applications of ORDO depend on its accuracy to effectively perform their tasks. In this paper, we implement an automated quality assurance pipeline to identify missing is-a relations in ORDO. We first obtain lexical features from concept names. Then we generate related and unrelated feature sharing concept-pairs, where a feature sharing concept-pair can further generate derived term-pairs. If an unrelated and related feature sharing concept-pair generate the same derived term-pair, then we suggest a potential missing is-a relation between the unrelated feature sharing concept-pair. Applying this approach …

Modeling Polar Cap Airglow Patch Intensities Using Three-Dimensional Ionospheres Produced By Data Assimilations, Michael R. Negale, J. V. Eccles, J. M. Holmes, S. V. Fridman, L. J. Nickisch

Space Dynamics Laboratory Publications

Discrete high density plasma structures in the Earth’s ionosphere that convect across the polar cap from the dayside to nightside are known as polar cap patches. Patches can interfere and disrupt satellite and HF communications, and therefore, accurate forecasting and modeling of this phenomenon would be greatly beneficial. In this study we have utilized the Global Positioning System Ionospheric Inversion (GPSII) data assimilation model using electron density measurements from the northward looking Resolute Bay Incoherent Scatter Radar (RISR-N) and total electron content (TEC) from ground based Global Navigation Satellite System (GNSS) receivers to reconstruct the high latitude ionosphere. From the …

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Summary

Postharvest processing of agricultural produce is still done the conventional way in Bangladesh. Manual grading of agricultural produce, especially fruits and vegetables, is laborious and costly due to acute shortage of labor during the peak season, as well as difficulty maintaining the product quality. Machine vision system (MVS) applications are widely used nowadays as a non-destructive and cost-effective technology for automatically grading and sorting large volumes of produce in the packing house according to size, shape, color, texture, and surface defects. In this study, a simple MVS was constructed measuring different color features of mango fruit surface as a …

Framework For The Use Of Extended Reality Modalities In Aec Education, Barbara Oliveira Spitzer, Jae Hoon Ma, Ece Erdogmus, Ben Kreimer, Erica Ryherd, Heidi Diefes-Dux

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The educational applications of extended reality (XR) modalities, including virtual reality (VR), augmented reality (AR), and mixed reality (MR), have increased significantly over the last ten years. Many educators within the Architecture, Engineering, and Construction (AEC) related degree programs see student benefits that could be derived from bringing these modalities into classrooms, which include but are not limited to: a better understanding of each of the subdisciplines and the coordination necessary between them, visualizing oneself as a professional in AEC, and visualization of difficult concepts to increase engagement, self-efficacy, and learning. These benefits, in turn, help recruitment and retention efforts …

Sro Roles And Teacher Behavioral Intervention Strategies: An Analysis On Behavioral Approaches And Student Suspensions., Ivan Benitez

Electronic Theses and Dissertations

Recently there have been nationwide calls for schools to end their contracts with local police departments in efforts to remove school resource officers (SROs) due to their criminalizing effect on students. Aiming towards racial equity in safety and discipline, advocates have suggested re-envisioning discipline through a restorative lens to minimize student harm. One approach which has been promising in student outcomes are behavioral intervention strategies. The current study contributes to the literature by examining the direct effects of SRO roles and teacher behavioral intervention strategies on student suspensions. Using factor analysis, I found three SRO roles: law enforcement officer, mentor, …

The Role Of Mri In Diagnosing Autism: A Machine Learning Perspective., Yaser Elnakieb

There is approximately 1 in every 44 children in the United States suffers from autism spectrum disorder (ASD), a disorder characterized by social and behavioral impairments. Communication difficulties, interpersonal difficulties, and behavioral difficulties are the top common symptoms. Even though symptoms can begin as early as infancy, it may take multiple visits to a pediatric specialist before an accurate diagnosis can be made. In addition, the diagnosis can be subjective, and different specialists may give different scores. There is a growing body of research suggesting differences in brain development and/or environmental and/or genetic factors contribute to autism development, but scientists …

Models And Algorithms For Trauma Network Design., Sagarkumar Dhirubhai Hirpara

Electronic Theses and Dissertations

Trauma continues to be the leading cause of death and disability in the US for people aged 44 and under, making it a major public health problem. The geographical maldistribution of Trauma Centers (TCs), and the resulting higher access time to the nearest TC, has been shown to impact trauma patient safety and increase disability or mortality. State governments often design a trauma network to provide prompt and definitive care to their citizens. However, this process is mainly manual and experience-based and often leads to a suboptimal network in terms of patient safety and resource utilization. This dissertation fills important …

Contracts Scholarship Beyond Materialisierung, Daniela Caruso

Faculty Scholarship

This comment aims to show how Klaus Eller's paper on ‘The Political Economy of Tenancy Contract Law raises the stakes of private law scholarship and contributes to the larger project of remodeling legal institutions in a progressive direction. The comment starts by contextualising the rapid spread of the Law and Political Economy (LPE) movement; illustrates through examples the generative impact of LPE on contemporary contracts scholarship; and highlights two strands of Eller’s original contribution to such literature: a welcome reflection on the value and limits of Materialisierung, and a radical widening of the private law inquiry to include institutional …

Reaching Syrians In Need: An Analysis Of Humanitarian Aid In The 21st Century., James Clark

Electronic Theses and Dissertations

The objective of this dissertation is two-fold. One is to critically consider humanitarian aid delivery to and through Syria via a lens that combines the humanities and social sciences. The fields of anthropology, political science and postcolonialism are employed to accomplish this. The second is to investigate the process involved in this delivery amid the country’s ongoing conflict. Combining these two facets provides a view of humanitarian aid as it relates to the conflict in Syria while applying a liberal arts-humanities approach. The introduction establishes the basis to discuss the existence of aid providers and those in need of aid …

Effects Of Top-Down Attention And Individual Differences On Recognition Memory And Recollective Experience., Anna Kelley

Electronic Theses and Dissertations

Memory accuracy and detail hold practical importance, and psychology has studied means to improve memory. One such means is performing visually guided saccades immediately before a memory test. Previous work has found this intervention to improve memory performance, an effect dubbed Saccade-Induced Retrieval Enhancement or SIRE. The top-down attentional control account posits that SIRE occurs because saccades activate attentional control regions in the brain, which contributes to executing top-down attentional control when searching memory. The current experiment tested this account of SIRE by attempting to replicate previous results and investigating whether a different attentional task, the Revised Attention Network Test …

Self-Regulation In Young School-Aged Children With Williams Syndrome., Holley Arnold

Electronic Theses and Dissertations

My dissertation included two manuscripts which broadly focused on the self-regulation abilities of young school-aged children with Williams syndrome (WS), a rare neurodevelopmental disorder. Children with WS often exhibit mild to moderate intellectual disability (Kozel et al., 2021), impairments in behavioral and emotional regulation (Greiner de Magalhães et al., 2022), low effortful control (Leyfer et al., 2012), and deficits in adaptive skills (Brawn & Porter, 2018). In the first manuscript, the performance of children with WS on a gift-wrap delay of gratification task was characterized. In the second manuscript, the concurrent effects of the ability to regulate emotions, the ability …

The goal of the project is to provide a DC input into BESS and test the system’s functionality. Initially, a Photovoltaic Thevenin Equivalent was expected to be utilized …

Diy Cell Incubator, Hayden James Jeanor

Electrical Engineering

The purpose of creating a cell Incubator is for the development of cell and tissue production in laboratory settings. Large scale research projects and the medical community grow cells for various reasons, including experiments and creating tissue for patients. However, they cannot simply depend on growing cells in a petri dish that sit on a rack at room temperature. To grow heathy cells in the fastest way possible, they use cell incubators. Cell incubators create an atmosphere within the incubation bay that is designed to promote cell growth. The three main components that need to be constantly regulated, using a …

Let's Get Real: Weak Artificial Intelligence Has Free Speech Rights, James B. Garvey

Fordham Law Review

The right to free speech is a strongly protected constitutional right under the First Amendment to the U.S. Constitution. In 2010, the U.S. Supreme Court significantly expanded free speech protections for corporations in Citizens United v. FEC. This case prompted the question: could other nonhuman actors also be eligible for free speech protection under the First Amendment? This inquiry is no longer a mere intellectual exercise: sophisticated artificial intelligence (AI) may soon be capable of producing speech. As such, there are novel and complex questions surrounding the application of the First Amendment to AI. Some commentators argue that AI …

Medical Harm Without Negligence, Valerie Gutmann Koch

Fordham Law Review

In December 2019, seven women from one family underwent highly invasive surgeries based on genetic test results that indicated that each were at significant risk of developing cancer by age seventy. Subsequently, after procedures that (among other things) permanently scarred and disfigured their bodies and ended their chances of having biological children, they learned that their particular mutation was not, in fact, pathogenic.

This Article focuses on a previously under-recognized problem: what happens when a patient’s previously classified pathogenic variant is downgraded to uncertain (or even benign) status? Intuitively, it might seem that the genetic testing company, the surgeons, or …

Enhancing Motor Imagery Decoding Via Transfer Learning, Olawunmi George, Sarthak Dabas, Abdur Sikder, Roger Smith, Praveen Madiraju, Nasim Yahyasoltani, Sheikh Iqbal Ahamed

Computer Science Faculty Research and Publications

Motor imagery (MI) is arguably one of the most common brain–computer interface (BCI) paradigms. The decoding process, in many cases, involves the use of small amounts of data gathered over a period. The decoding performance might therefore be limited, due to the size of available data. Also, the non-stationarity of signals across sessions and subjects can pose a challenge to effective decoding. To solve these challenges, transfer learning is proposed as the suitable approach, which could yield optimal performance even with small amounts of data and handle the non-stationarity of signals with adaptation. It has been applied across domains and …

An Interprofessional Prediabetes And Diabetes Self--Management Education Quality Improvement Project Among Vulnerable Populations At A Tuberculosis Hospital, Robert Saul Castro Natal

Doctor of Nursing Practice

Background. Patients greatly benefit from diabetes self-management education (DSME) as it boosts knowledge and self-efficacy, decreases body weight, fasting blood sugar, and hemoglobin A₁C levels, and improves overall health outcomes in a cost-effective manner. Unfortunately, many individuals with prediabetes and diabetes who qualify for DSMEs do not attend these classes nor receive sufficient prediabetes and diabetes support elsewhere to attain guideline recommended metrics. However, individuals from vulnerable populations and without DSME education experience disproportionate diabetes-related complications worsening health outcomes. Aims: Increase general prediabetes and diabetes knowledge, facilitate behavior change, improve glycemic, metabolic, and lipid values, and increase …

“Together We Arrived And Together We Shall Leave”: The Gouverneur Parents Association And The Politics Of Race And Disability In Postwar New York, Jorge A. Matos

Publications and Research

This essay documents the history of the Gouverneur Parents Association (GPA), a group of mostly Black and Latinx parents whose disabled children were institutionalized at the Gouverneur Division of the infamous Willowbrook State School in New York City. The GPA, in coalition with Black, Latinx, and White parents and activists, led a campaign during the 1970s and 1980s to close Willowbrook, then part of a national network of sites denounced by disability activists during the heyday of the deinstitutionalization movement. In this essay I argue that the postwar migration of Black and Latinx communities into New York City amid an …

Why Energy Efficiency Is Needed In Rwanda, Jean Ishinzibigwi

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Perspective on the benefits of energy efficiency and cost savings on energy was changed by the experience of working with the Nebraska Industrial Assessment Center. Visiting various industrial locations in Nebraska to see how different energy-saving techniques are employed to save money on energy costs and reduce energy waste. Rwanda can put several ideas into action to lessen the energy loss, which is too much now.

The government's Ministry of Infrastructure (MININFRA) and other departments are crucial to Rwanda's energy sector. The primary ministry in charge of developing renewable energy is MININFRA (methane, peat, geothermal, solar and wind energy). The …
