Mlp And Rbf Algorithms In Finance: Predicting And Classifying Stock Prices Amidst Economic Policy Uncertainty, Bushra Ali, Khder Alakkari, Mostafa Abotaleb, Maad M. Mijwil, Klodian Dhoska

Mesopotamian Journal of Big Data

In the realm of stock market prediction and classification, the use of machine learning algorithms has gained significant attention. In this study, we explore the application of Multilayer Perceptron (MLP) and Radial Basis Function (RBF) algorithms in predicting and classifying stock prices, specifically amidst economic policy uncertainty. Stock market fluctuations are greatly influenced by economic policies implemented by governments and central banks. These policies can create uncertainty and volatility, which in turn makes accurate predictions and classifications of stock prices more challenging. By leveraging MLP and RBF algorithms, we aim to develop models that can effectively navigate these uncertainties and …

Removal Of Pfoa/Pfos In Water Using Electrocoagulation And Associated Life Cycle Impacts And Financial Costs, Tianhong Mu

Electronic Theses & Dissertations (2024 - present)

Electrocoagulation (EC) with a zinc anode demonstrated promising results to remove perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) from an aqueous solution. However, the energy requirement for EC is usually very high due to water electrolysis or aeration. The second chapter of this dissertation aims to reduce energy consumption using an air-cathode in EC (ACEC) to supply oxygen electron acceptor without aeration for attenuating PFOA/PFOS in this new configuration. For the high PFOA concentration (0.25 mM), ACEC with 45 min of the reaction time exhibited an excellent PFOA removal (99.8 ± 0.3% removal) comparable to an EC with aeration (EC-aeration, …

The Retention Of Urban Secondary Special Education Teachers: Why Stay?, Chelsea Quezada

Electronic Theses & Dissertations (2024 - present)

Utilizing interview data collected from six urban secondary special education teachers (SETs), this qualitative study explored why these individuals chose a teaching position in special education in urban secondary schools and why they remained in those positions despite the challenges inherent to that setting. From role and organizational theory, we know that retention is the result of a complex set of socialization factors that either support successful integration into the SET role or impede the individual’s efforts to achieve fit within the given organization. This study sought to understand how these six SETS experienced the socialization process and which factors …

Situating The Modern Public Trust Doctrine In Trust Law: The Duty Of Loyalty And The Case For Bifurcated, De Novo Judicial Review, Edward A. Zelinsky

Articles

This article situates the modern public trust doctrine (PTD) in contemporary trust law. Grounding the PTD in trust law leads to two important corollaries. First, the PTD planted in trust law imposes upon government actors and agencies trust law’s fiduciary duty of loyalty. In the context of the PTD, that duty of loyalty runs to the public as the beneficiary of the PTD. Second, faced with plausible claims that this fiduciary duty of loyalty to the public has been violated, courts should apply trust law’s de novo standard of review to those administrative and legislative decisions alleged to impair public …

Improving Growth Models Of Cultivated Sugar Kelp, Saccharina Latissima, By Accounting For Intraspecific Variation In Thermal Tolerance, Ruby Krasnow, Sara Gonzalez, Scott Lindell

Student Publications [Scholarly]

Dynamic models of sugar kelp (Saccharina latissima) growth are used to estimate the production potential of seaweed aquaculture in many regions around the world. These models do not currently account for the existence of S. latissima ecotypes that are adapted to regional environmental conditions, particularly temperature. We tested the hypothesis that recalibrating the temperature parameters of a dynamic energy budget model using literature data for S. latissima from regions with a similar climate to the region of interest would result in more accurate predictions than using a general species-wide temperature response curve. Calibrating the model using data from warm regions …

Racial Bias, Accomplice Liability, And The Felony Murder Rule: A National Empirical Study, G. Ben Cohen, Justin D. Levinson, Koichi Hioki

Akron Law Faculty Publications

Two long criticized prosecutorial tools—the felony murder rule and the accomplice liability doctrine—play an outsized role in the operation of American homicide law. Though each of these tools have separately faced intense criticism for their resistance to the supposedly foundational principles of moral culpability and individual responsibility, their legacy is also defined by the way they function symbiotically and specifically to heighten racialized punishment. This Article addresses the weighty combined reach of the accomplice liability doctrine and felony murder rule, and proposes that racial bias has fueled the operation and survival of these tools. Specifically, it suggests that implicit racial …

Expert Malpractice, James R. Steiner-Dillon

Akron Law Faculty Publications

The provision of expert testimony in litigation has become a big business. The paradigmatic testifying expert is no longer the “amateur” expert who maintains a separate professional identity and testifies only once, or at most sporadically, in litigation to which their expertise is uniquely pertinent. Rather, they are a professional provider of litigation support services who spends a substantial part of their time, and derives a substantial part of their income from, consulting on pending or contemplated lawsuits. Legal rules concerning the provision of expert testimony continue to apply the former, obsolete paradigm of the testifying expert. This conflict of …

Inheriting Shame: A Critical Analysis Of “The Eugenics Review”, Brygette R. Kunde

All Student Theses and Dissertations

The Eugenic Society was a group of self-proclaimed "Race-Improvers" who came together intending to better humanity by founding The Eugenics Society and producing, "The Eugenics Review,” a publication that circulated throughout the United States from 1909 until 1968. Eugenicists wrote on diverse topics surrounding race betterment by introducing scientific methods that were both inhumane and injustice based on their parochial, perceived notions that inequalities are ubiquitous. Categories like religion, race, class, nationality, gender, and many others have been the sources of stigmatization, discrimination, and conflict throughout the centuries in the United States.

Violence & Volition: Choice, Acceptance, And Identity In Selected Works By Flannery O'Connor, Kurt Vonnegut, And Cormac Mccarthy, Lisa Farrell

All Student Theses and Dissertations

Violence is ubiquitous in American Fiction, especially in the twentieth and twenty-first centuries. In “A Good Man is Hard to Find”, “Good Country People”, and “The Displaced Person” Flannery O’Connor highlights the choices people make within that violence can directly affect the results of that violence. Kurt Vonnegut’s Slaughterhouse-Five, through the character of Billy Pilgrim, extends choices around violence even further, suggesting that inaction is sometimes the best plan. Cormac McCarthy’s No Country for Old Men highlights how a combination of action and inaction, depending on the situation, can help or hurt someone when violence surrounds them.

Protective Factors Among Native Born And Immigrant Undergraduate And Graduate Students Enrolled In American Colleges: Predictive Validity Of Acculturation, Family Involvement, Academic Persistence, Grit, And Sense Of Belonging, Agnieszka Tulowiecka

All Student Theses and Dissertations

Achieving higher education goals and becoming acculturated to the social and economic values of the U.S. is critical for the success of immigrants. According to a survey by the Pew Research Center, immigrants are estimated to account for 93% of the nation's workforce population growth over the next three decades (Pew, 2013). However, much of the existing empirical work on postsecondary outcomes among immigrant youth mainly focuses on the challenges and deficits faced by this group, as well as differences between racial/ethnic categories. This This emphasis might potentially mask within-group differences (e.g., ethnic/regional variations) that arise from unique pre- and …

Introductory Activity For Generative Ai, Josh Anthony

English Faculty Teaching Materials

The basic mechanics of this activity are simple: choose a reading from class and try to manipulate the LLM to recreate it as close to the original as possible. As a rule, I generally try to produce and run activities that are modular, interchangeable, and adaptable. This activity is no different. In one course, we used the prompt and only the prompt—no scaffolding. In other courses, we scaffolded LLMs, understood how prompt engineering might work, and worked as a class to construct the prompt we thought would produce a suitable outcome.

For students, the limitations of the LLMs become clear …

A Case Study To Determine The Literacy Needs Within Remediation Practices For Students In Grades 1-3, Miranda M. Gillis

Doctor of Education Dissertations

In order to effectively teach reading, it is not enough for a teacher to possess knowledge and skills alone. It is equally important to use evidence-based instructional approaches and interventions, especially when working with at-risk or struggling students. Without appropriate instructional materials and contexts, even the most competent teacher may fail to teach essential literacy skills, such as phonemic awareness, phonics, vocabulary, spelling, and writing processes. As the importance of teacher quality gains attention at the state and federal levels, lesson structure and allocation of lesson time for literacy-related activities have become a focus. The emergence of structured literacy underscores …
