Script Combination For Enhanced Story Understanding And Story Generation Systems, Megan Mckenzie, Alexis Kilayko, Jamie C. Macbeth, Scott Carter, Katharine Sieck, Matthew Klenk

Computer Science: Faculty Publications

Scripts, knowledge structures defining sequences of events in stereotypical social situations, were traditionally used to simulate the ways in which people can infer unstated details in understanding a story. In this paper, we describe the MUltiple SCRipt AcTivator (MUSCRAT), and the Script Combination Applier Mechanism (SCAM), significant enhancements of Cullingford’s Script Applier Mechanism which accomplish two novel aims. One system, MUSCRAT, is able to activate more than one script and use them during a story understanding process. The second system, SCAM, uses scripts for story generation, using script variables as “terminals” for combining two or more scripts together to create …

Lowering The Stakes Of The Employment Contract, Aditi Bagchi

Faculty Scholarship

Every country has to make hard choices about the distribution of entitlements. But employers control the entitlements that individual Americans enjoy to a far greater extent than those in other rich democracies. In this Essay, I argue that, in the absence of the political consensus necessary to deliver state solutions to political questions, employers here are assigned an exaggerated role in employees’ lives. Government incentives for and directives to employers have become a strategy of political deflection. The effect has been to raise the stakes of employment well beyond the scope of those terms and conditions that relate to attracting …

Law And The Moral Dynamics Of Collective Action, Aditi Bagchi

Faculty Scholarship

Many moral demands on social groups cannot be met without cooperation among group members. In some cases, individual action does not advance the collective moral interest at all without some threshold level of cooperation by other group members. Is an individual required to act as if others will cooperate even if she knows that they will not? This Article argues that individuals may take into account the reality of pervasive noncooperation and decline to attempt cooperation. Only ex ante mandatory rules can solve moral collective action problems. In a political community, those rules are public law. The most compelling argument …

Breaking The Mold: Haunted Attraction Mazes; A Study In Reducing Predictability & Increasing Intensity, Within Unconventional Halloween Attraction Experiences, Amy Avalos

Electronic Theses and Dissertations, 2020-2023

Every enchanted Fall season, a segment of the public flocks to a multitude of haunted Halloween attractions across the U.S., to experience fear as a form of amusement and entertainment. Psychologists continue to research the physiological and cognitive behaviors that are associated with fear and the "fight or flight" responses that are triggered when individuals are engaged in a heighten sense of danger. However, as guests traverse through these haunted attraction experiences, it's commonplace for guests to enter into these typical modes of "fight or flight" behaviors very quickly. Once this response kicks in, the guests' instinct is to scramble …

A Theoretical Prototype For Narrative And Interactive Development Within A Theme Park Parade, Carson Luter

Electronic Theses and Dissertations, 2020-2023

While theme park parades have developed with technology and guest demands, there is an opportunity to continue innovating the medium with additional guest interactivity. This thesis tracks experiential comparatives that provide iterative components to be utilized for a new theme park parade concept; parade "show stops" that allow for guests to approach the parade floats up-close, participatory entertainment offerings with live actor-driven branching narratives, roleplay and gameplay-driven interactive experiences, and theme park parades that follow a direct linear narrative. What follows is a theme park parade design concept, accompanied by a production and operational plan, that combines the existing spectacle …

Utilizing Dramaturgy To Activate Creativity In Young Audiences, Joni Newman

Electronic Theses and Dissertations, 2020-2023

Theatre for Young Audiences companies in the United States rely heavily on recognized titles to bring in audiences. As a result, most of their productions are adapted from recognizable titles, including films, television series, and popular literature. These adaptations draw audiences in that may not otherwise go to the theatre, which is especially important within the world of TYA where the target audience (children) only gains access to a theatre through adult caregivers. Additionally, most children go to the theatre as part of school field trips, further encouraging season selections that will fill educational needs in addition to providing theatrical …

Artificially Intelligent Boards And The Future Of Delaware Corporate Law, Christopher Bruner

Scholarly Works

The prospects for Artificial Intelligence (AI) to impact the development of Delaware corporate law are at once over- and under-stated. As a general matter, claims to the effect that AI systems might ultimately displace human directors not only exaggerate the foreseeable technological potential of these systems, but also tend to ignore doctrinal and institutional impediments intrinsic to Delaware's competitive model – notably, heavy reliance on nuanced and context-specific applications of the fiduciary duty of loyalty by a true court of equity. At the same time, however, there are specific applications of AI systems that might not merely be accommodated by …

Are Constitutional Rights Enough? An Empirical Assessment Of Racial Bias In Police Stops, Michael Frakes, Rohit Asirvatham

Faculty Scholarship

This Article empirically tests the conventional wisdom that a permissive constitutional standard bearing on pretextual traffic stops—such as the one announced by the Supreme Court in Whren v. United States—contributes to racial disparities in traffic stops. To gain empirical traction on this question, we look to state constitutional law. In particular, we consider a natural experiment afforded by changes in the State of Washington’s rules regarding traffic stops. Following Whren, the Washington Supreme Court first took a more restrictive stance than the U.S. Supreme Court, prohibiting pretextual stops by police officers, but later reversed course and instituted a laxer standard, …

“Second-Class" Rhetoric, Ideology, And Doctrinal Change, Eric Ruben, Joseph Blocher

Faculty Scholarship

A common refrain in current constitutional discourse is that lawmakers and judges are systematically disfavoring certain rights. This allegation has been made about the rights to free speech and free exercise of religion, but it is most prominent in debates about the right to keep and bear arms. Such “second-class” treatment, the argument goes, signals that the Supreme Court must intervene aggressively to police the disrespected rights. Past empirical work casts doubt on the descriptive claim that judges and policymakers are disrespecting the Second Amendment, but that simply highlights how little we know about how the second-class argument functions as …

Synthesis, In Silico And Pharmacological Evaluation Of New Thiazolidine-4-Carboxylic Acid Derivatives Against Ethanol-Induced Neurodegeneration And Memory Impairment, Shagufta Naz, Lina Tariq Al Kury, Humaira Nadeem, Fawad Ali Shah, Rehan Zafar Paracha, Muhammad Imran, Shupeng Li, Aman Ullah

All Works

Introduction: Several studies revealed that alcohol utilization impairs memory in adults; however, the underlying mechanism is still unclear. The production of inflammatory markers and reactive oxygen species (ROS) plays a major role in neurodegeneration, which leads to memory impairment. Therefore, targeting neuroinflammation and oxidative distress could be a useful strategy for abrogating the hallmarks of ethanol-induced neurodegeneration. Moreover, several studies have demonstrated multiple biological activities of thiazolidine derivatives including neuroprotection. Methods: In the current study, we synthesized ten (10) new thiazolidine-4-carboxylic acid derivatives (P1-P10), characterized their synthetic properties using proton nuclear magnetic resonance (1 H-NMR) and carbon-13 NMR, and further …
