Stock Price Trend Prediction Using Emotion Analysis Of Financial Headlines With Distilled Llm Model, Rithesh H. Bhat

Computer Science and Engineering Theses - Archive

Capturing the volatility of stock prices helps individual traders, stock analysts, and institutions alike increase their returns in the stock market. Financial news headlines have been shown to have a significant effect on stock price mobility. Lately, many financial portals have restricted web scraping of stock prices and other related financial data of companies from their websites. In this study we demonstrate that emotion analysis of financial news headlines alone can be sufficient in predicting stock price movement, even in the absence of any financial data. We propose an approach that eliminates the need for web scraping of financial data. …

Natural Language Generation From Large-Scale Open-Domain Knowledge Graphs, Xiao Shi

Computer Science and Engineering Dissertations - Archive

This dissertation delves into the realm of natural language generation (NLG) from expansive open-domain knowledge graphs, aiming to bridge the gap between existing methods primarily tested on limited datasets and the demands of real-world large-scale, diverse graph structures. Prior works in NLG often relied on small-scale or restricted datasets, neglecting the complexities of broader knowledge graphs. To address this, we introduce a new dataset called GraphNarrative, designed to encompass a wide range of graph structures and enhance the realism of NLG tasks.

The core contribution of this research lies in devising a novel approach to mitigating information hallucination, a common …

Claim Sensing: A Study Linking Factual Claims To Human Behaviors On Social Media, Zeyu Zhang

Computer Science and Engineering Dissertations - Archive

The ubiquity of social media has transformed it into a rich source for reflecting people's opinions, behaviors, and interactions. Users frequently encounter factual claims in news, stories, and political statements, which can be either true or false. These claims significantly shape people's minds and behaviors, influencing not only individual perspectives but also broader public discourse. This study explores individuals' behaviors and perceptions toward factual claims by leveraging the concept of "check-worthiness" to analyze the relationship between such claims and user behaviors across datasets containing tens of millions of social media posts, particularly tweets from the platform X (formerly Twitter).

All-Optical Signal Processing With Fiber-Based Parametric Wavelength Converters, Cheng Guo

Electrical Engineering Dissertations - Archive

The optical signal degradation by optical amplifier noise set the fundamental limit of link reach in the fiber-optics networks. The industrial solution is to use the optical-electrical-optical (OEO) regenerator to clean up the noise at the expense of high-speed electronics and extra cost of laser and photodetectors. All-optical signal processing, enabled by nonlinear optics and optical fiber, intrinsically provides 2-order of magnitude higher processing bandwidth and seamless interface to fiber communication channels. However, there is no robust phase-preserving regenerator that has been experimentally demonstrated without sophisticated polarization tuning and without instable interferometric structure. In this project, we explore the applications …

The Influence Of Intracellular Photosymbiosis On The Evolution And Function Of Cnidarian Immunity, Madison A. Emery

Biology Dissertations - Archive

Intracellular photosymbiosis with Symbiodiniaceae is facilitated by cnidarian immunity as it is required for symbiont recognition and is subsequently suppressed to maintain stable intracellular symbiosis. To date, it is unclear how the cnidarian-Symbiodiniaceae symbiosis influences immune gene repertoires, immune gene expression, and disease pathology across its independent evolutions. To address these knowledge gaps, my dissertation approaches studying the cnidarian-Symbiodiniaceae symbiosis through a comparative lens to determine how it shapes immune gene evolution and immune responses in divergent symbiotic cnidarian species. In chapter two I survey eight non-symbiotic and seven symbiotic cnidarians proteomes for four families of pattern recognition receptors (PRRs) …

Evaluation Of A Simulation-Based, E-Learning Intervention To Develop Prelicensure Nursing Students' Clinical Competency To Recognize Tracheostomy Airway Complications, Ruth Bargainer Tobin

Nursing Dissertations - Archive

Tracheostomy airway patient safety errors are a global, yet preventable problem. Unrecognized tracheostomy airway complications lead to patient deterioration, resulting in hypoxic brain damage and death or permanent disability. The majority of preventable tracheostomy events occur after patient discharge from the intensive care setting. These catastrophic events are attributed to deficiencies in competent and safe nursing care. Prelicensure nursing students have few clinical opportunities to learn tracheostomy management and may enter nursing practice lacking the clinical competency (CC) to recognize a tracheostomy airway problem. Simulation is a modality for learning high-risk skills such as tracheostomy care (TC) in a setting …

New Methods In Electrical Source Imaging Based On Eeg And Post-Mortem Pathology Data, Julio Cesar Enciso Alva

Mathematics Dissertations - Archive

A central task for Neuroscience is to determine the location of electrical activity of neural origin inside the brain. Electrical signals can be recorded at a high resolution in time but low resolution in space, thus making it difficult to locate their source unambiguously. Electrical Source Imaging (ESI) is a particular framework for neural electrical source location; it is possible by modeling any additional information we may have about the electrical sources. For instance, minimal-norm estimators assume that the most plausible estimation is that with a lower norm. However, these estimators possess a low resolution in space.

In this work, …

The first study investigated adults’ perceptions, as they were asked to rank instrument preferences for their hypothetical son and daughter. The second study examined the perceptions of seventh- and eighth-grade band students by allowing them to rate band instruments based on their gender perceptions. The third study investigated the perceptions and experiences of university band students related to gender norms and instruments utilizing a survey and interview process. The results provided evidence that instrument gender perceptions and stereotypes can change, and they suggest that intentional …

“Criticize The Way You Fly”: Negotiations Of Femininity And Motherhood Among Young Disabled Women, Alicia Leon Luna

Sociology & Anthropology Theses - Archive

Disabled women are often excluded from the reproductive rights movement based on the wrongful assumption that women’s disability makes them unfit for motherhood. The social proscription of parenting by disabled women creates reproduction rights issues as it blocks pathways to parenthood while simultaneously ignoring the ever present influence mothering ideology (i.e., the motherhood mandate) has on the gender identity of these women. Research on disabled motherhood is sparse; thus, this study seeks to add to it by examining the intersection of disability, femininity, and motherhood through the lens of young childless disabled women. In-depth interviews were conducted with 14 disabled …

Differentially Unwell: On Mimi Khúc's "Dear Elia", Seo-Young J. Chu

Publications and Research

[...] Inviting readers to reclaim the stigma of unwellness and collectively to "tend to our unwellness, together," Khúc approaches unwellness as a crucial resource for subverting the "wellness and unwellness" dichotomy entirely. After all, the opposite of "wellness" is not "unwellness"; the opposite of "wellness" does not exist. The opposition itself is an artificial framework, one that reductively harms more than it dialogically helps. We need to move away from these simplistic dualisms, Khúc suggests, and towards more generous, trauma-informed epistemologies. [...]

The Brussels Effect And The Extraterritoriality Of Delaware Corporate Law, William J. Moon

Faculty Scholarship

This essay explores possible shareholder claims in the United States that may arise  if and when member states of the European Union implement the proposed Directive  on Corporate Sustainability Due Diligence. As a doctrinal matter, legal compliance  obligations for corporations incorporated in Delaware extend beyond the borders of  the United States. Under Delaware law, shareholders can bring viable fiduciary suits  against directors and officers when corporations violate applicable “positive law.”  This jurisprudence, principally aimed at ascertaining whether directors and officers  betrayed shareholders by engaging in or facilitating lawbreaking, is not limited to  complying with American law. As Delaware corporations expand …

Identifying The Job Characteristics Affecting Construction Firm Employee Turnover Intention, Seog Jae Choi

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Researchers have proved that employees who have the intention to quit the organization, called turnover intention, have decreased productivity and may not fulfill their duties properly. The turnover intention has a negative relationship with the quality of core job characteristics of the organization. As the construction industry has distinctive characteristics compared to other industries, the job characteristics that influence turnover intention need to be explored separately. This study identifies job characteristics of the construction industry that can affect turnover intention. Through the literature review, autonomy, task identity, required skill variety, task significance, justification in assigning work location, and job security …

Shelter-Skelter: The New York City Homelessness Crisis, Brian J. Koluch

GLO 100 Introduction to Global Studies: Policy Analysis Papers

With 88,025 Homeless people, NYC was ranked #1 in Homelessness in America, having 70,000 more than the third greatest city, the Seattle Metropolitan area/King County. (HUD) This figure may lead one to infer that the procedures in the city aren’t effective. However, this paper paints a different picture. The introduction of the Coalition for the Homeless’ Consent Decree through the landmark Callahan v Carey case birthed the “Right to Shelter” movement. Low-income housing was expanded, while the DeBlasio framework to “End Homelessness” through on-the-ground social work flourished. Equal attempts at weakening the consent decree developed throughout city history.

The Relationship Between Offshore Wind Farms And Marine Wildlife In Rhode Island, Hanna Lloyd, Ashley Caputo, Brendan Foley, Catherine Chadwick, Savannah Szamborski

ENV 334 Environmental Justice

Despite political and environmental controversy, research has shown that not only do offshore wind farms have minimal impact on birds, whales, and benthic organisms, but they can actually be beneficial to marine ecosystems. However, many Rhode Island and Massachusetts citizens are concerned that the construction of the Revolution wind farm will decrease the biodiversity of marine ecosystems. Current research refutes these claims on the negative impacts of offshore wind farms, stating that their construction benefits benthic communities, has little to no impact on the health of whales, and only temporarily impacts migrating bird species. New and innovative technology has found …

Awakening To Activism: Exploring Disability Activism Through The Voices Of University Student Activists, Sophia Hirokawa

West Chester University Master’s Theses

In this study, I explored disability activist identity and activism through one-on-one, semi-structured qualitative interviews with four university activists who shared their personal stories of awakening to disability activism, using thematic analysis (Braun & Clarke, 2006) to explore themes. Each interviewee had a unique form of disability activist identity and a multifaceted process of awakening to that identity. They identified strengths in the disability activist community, such as a supportiveness, persistence, and uniqueness, but they also identified challenges, such as ineffectiveness of laws and policies, discrimination, and a lack of accessibility and awareness. The results of this study illuminate the …
