Visual Semiotics In Parks: Assessing Pictorial Symbol Effectiveness In Outdoor Recreation Settings, Miranda Jane Foster

Graduate Student Theses, Dissertations, & Professional Papers

As interest in outdoor recreation grows, so does the need for effective communication in parks and protected areas. With a larger, more diverse visiting population, managers face new challenges, including intensified recreational use, staffing demands, and barriers to communication presented by cultural and linguistic diversity (Manning et al., 2017; Perry et al., 2021). Effective, indirect communication tools, such as pictorial symbol signage, are essential for addressing these challenges. Pictorial symbol signs are widely used in recreational signage and serve as vital indirect management strategies for communicating to diverse visitors as a universal visual language (Davies et al., 1998). However, research …

A Pilot Training Program For The Cultural Formulation Interview In School-Based Assessment, Jaida A. Lilly

Graduate Student Theses, Dissertations, & Professional Papers

School psychologists are responsible for promoting and maintaining an equitable, inclusive environment for all students to learn. For those who work in school settings, assessment of a student’s academic, mental health, and behavioral difficulties are often a significant component of school psychological practices. However, for various reasons, the assessment process can be flawed, and can unintentionally perpetuate systems of oppression in school-settings; this is especially true when working with children from culturally and linguistically diverse (CLD) backgrounds. Within culturally responsive assessment, conducting interviews is necessary for connecting with and effectively supporting the student and family. The Cultural Formulation Interview (CFI) …

From Philosophy To Nlu: Evolving Definitions With Research Hypotheses, Jian Wu, Sarah Rajtmajer

Computer Science Faculty Publications

Over the past decades, alongside advancements in natural language processing, significant attention has been paid to training models to automatically extract, understand, test, and generate hypotheses in open and scientific domains. However, interpretations of the term hypothesis for various natural language understanding (NLU) tasks have migrated from traditional definitions in the natural, social, and formal sciences. Even within NLU, we observe differences defining hypotheses across literature. In this paper, we overview and delineate various definitions of hypothesis. Especially, we discern the nuances of definitions across recently published NLU tasks. We highlight the importance of well-structured and well-defined hypotheses, particularly as …

Spanking And Children's Approaches To Learning: Estimates From A Longitudinal Matched-Sample Design, Jeehye Kang, Christina M. Rodriguez

Sociology & Criminal Justice Faculty Publications

One form of corporal punishment commonly used in the United States is spanking. Spanking is a well-known risk factor for adverse child development, although its influence on children's approaches to learning (ATL) has been largely overlooked. Existing research is particularly limited in inadequately considering multiple confounds and selection biases in children's exposure to spanking. This study examined the links between spanking and children's ATL, using a matched-group design to strengthen causal estimates among children aged 5 to 7.5 (N = similar to 12,800) from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011. Entropy-balanced matching mitigated selection and confounding biases, …

Overcoming Racial Harms To Democracy From Artificial Intelligence, Spencer A. Overton

GW Law Faculty Publications & Other Works

While the United States is becoming more racially diverse, generative artificial intelligence and related technologies threaten to undermine truly representative democracy. Left unchecked, AI will exacerbate already substantial existing challenges, such as racial polarization, cultural anxiety, antidemocratic attitudes, racial vote dilution, and voter suppression. Synthetic video and audio (“deepfakes”) receive the bulk of popular attention—but are just the tip of the iceberg. Microtargeting of racially tailored disinformation, racial bias in automated election administration, discriminatory voting restrictions, racially targeted cyberattacks, and AI-powered surveillance that chills racial justice claims are just a few examples of how AI is threatening democracy. Unfortunately, existing …

Fine-Tuned Large Language Models (Llms): Improved Prompt Injection Attacks Detection, Md Abdur Rahman, Hossain Shahriar, Guillermo Francia, Fan Wu, Alfredo Cuzzocrea, Sheikh Iqbal Ahamed

Computer Science Faculty Research and Publications

Large language models (LLMs) are becoming a popular tool as they have significantly advanced in their capability to tackle a wide range of language-based tasks. However, LLMs applications are highly vulnerable to prompt injection attacks, which poses a critical problem. These attacks target LLMs applications through using carefully designed input prompts to divert the model from adhering to original instruction, thereby it could execute unintended actions. These manipulations pose serious security threats which potentially results in data leaks, biased outputs, or harmful responses. This project explores the security vulnerabilities in relation to prompt injection attacks. To detect whether a prompt …

The system operates as a pipeline comprising three deep learning models integrated with a custom-designed database. Two models form the Ancient Script Recognition network (ASR-net), which digitizes sequences of graphemes from Indus seals, similar to Optical Character Recognition for modern languages. The third model, the Motif Identification network (MI-net), identifies recurring motifs—distinctive symbols or …

Categorical Perception Of The Index Finger As An American Sign Language Phonological Construct, Lareina Hingson, Jeffrey Jack Green, Brooklyn Lorenc

Faculty Publications

In American Sign Language, specific handshapes found in the manual alphabet and/or numbering system (such as the pointed index finger—the number “1”—and its bent counterpart—the letter “x”) are assumed to be phonologically distinct under the rationale that bentness of the finger(s) constitutes a phonemic distinctive feature. This study investigates this notion, building on previous behavioral studies of American Sign Language categorical perception of bentness of the index finger. We examined varying levels of bentness between 180◦ and 90◦ using a scale ranging from the signs BLACK and SUMMER in the standard dialect. Experiment 1 found that when presented with all …

Authenticity At Issue: Legislative Resistance To Gen Ai In Constituent Communication, Amy Mccoy

Iowa Journal of Communication

As legislators manage a fast-paced environment including an increasing number of legislative proposals, this research examines their perceptions around and understanding of generative artificial intelligence (Gen AI) and its potential applications related to constituent communications. This study explores how technological shifts in legislative communication, examined through New Media and Constructivist lenses, are interpreted and experienced by lawmakers. Through a mixed-methods approach using survey and interviews, this research provides insights on the contradiction of using Gen AI for legislative efficiency with concerns of how it may impact perceptions of authenticity and affect democratic engagement.

Toxic Sweetness And Abstinence: The Citationality Of Robert Lustig's Anti-Sugar Rhetoric, Tyler J. Snelling

Iowa Journal of Communication

Robert Lustig’s (2009) lecture on YouTube “Sugar: The Bitter Truth” animated a widespread conversation about whether sugar poisons bodies. Discourse following the lecture warrants analysis to gage how the meaning of the lecture transformed from a critique of food systems into individual actions. I argue that citationality of “Sugar: The Bitter Truth” fosters healthism by grounding sugar’s toxicity in scientific and affective reasoning that compels individual actions like abstinence from sugar. The pediatrician's lecture enabled the construction of a supposedly "moral eater" who removes sugar from consumption to avoid the poison's consequences. This paper offers tools for examining the spread …

Remembering July 36th: A Semiotic Analysis Of The Student-People's Revolutionary Graffiti, Jordan D. Smith

Iowa Journal of Communication

The use of graffiti as a tool for political solidarity has been universally documented in the academic lexicon. Using symbols of resilience, justice, disenfranchisement, and hope, graffiti is a unique phenomenon for visual rhetorical studies. The variety of artifacts spanning millennia document socio-political shifts, economic disparity, and messages of rebirth for systems in crisis. This study conducts a semiotic analysis of protest graffiti created during Bangladesh’s Student-People Uprising of July 2024 to explore how visual and linguistic signs construct messages of hope and solidarity. Using Ferdinand de Saussure’s (2021) semiotic framework, this research examines the symbolic and rhetorical elements present …

Per Se Non-Takings, Nestor M. Davidson, Timothy M. Mulvaney

Faculty Scholarship

In the discourse on the Takings Clause, disputes over methodology have long formed a kind of proxy war, with per se rules ordinarily underwriting strong constitutional protection for property rights and ad hoc standards more often vindicating public interests. At a moment when the Supreme Court is increasingly embracing the rules end of this rules–standards spectrum, this Article offers a novel perspective to challenge the conventional link between categorical reasoning and classical liberal conceptions of constitutional property.

To do so, the Article excavates a vast body of law denying takings liability through rule-like reasoning, an approach the Article calls per …

Fluctuating “Indianness” Or “Belonging” : Singapore Indian Dancers And Their Encounter With Southeast Asia At Ramayana Festival, Yoshiaki Takemura

Asian Review

This article investigates the dynamic relationship between cultural heritage and regional identity among the Indian diaspora in Singapore, specifically focusing on the experiences of classical Indian dancers. Historically, the process of “Indianization” deeply influenced the cultural landscape of Southeast Asia, evidenced by the regional prominence of the Hindu epics, the Ramayana and the Mahabharata. Using the context of a regional Ramayana Festival, this paper analyzes how Singaporean Indian dancers, while performing art forms rooted in the Indian subcontinent, negotiate their identity when confronted with diverse Southeast Asian interpretations of the same epic narrative.The study argues that this encounter forces a …

From Realism And Socio-Cognitivism To Ai Constructs: Enhancing Domain Analysis Through Artificial Intelligence?, Martin Thellefsen, Alon Friedman

School of Information Faculty Publications

Introduction. This study explores the integration of artificial intelligence (AI) within the framework of domain analysis (DA), traditionally grounded in socio-cognitive and realist perspectives. The aim is to assess AI's potential to enhance DA's focus on contextual and disciplinary knowledge, while examining possible epistemological challenges.

Method. Building on established concepts from Hjørland’s socio-cognitive DA framework, this paper employs a theoretical review to examine AI's capacity to augment DA by improving classification, retrieval and interdisciplinary mapping within knowledge organisation.

Analysis. The study critically analyses how AI may either enhance or disrupt DA’s philosophical foundations by potentially reducing domain specificity. Particular attention …

Fixation On Viruses: Eye-Tracking, Image-Based Agency, And Fear-Appeal Desensitization, Braden Bagley, Lijie Zhou, Hayden Coombs, Matthew Barton

Iowa Journal of Communication

This study examined the effects of image-based assignment of agency (IAA) on COVID-19 and flu fear-appeals by employing eye-tracking technology. Volunteers participated in a 2x2x2 between-groups experiment. Fixation-count and fixation-duration were collected by a Tobii Pro X3-120 Screen-Based Eye-Tracker. After reviewing a fact sheet, participants answered a 29-item survey that included items aligning with the extended parallel process model. The flu/agentic-image/virus-agentic-language message produced significantly higher fixation-frequency to the image and a higher perception of severity than the COVID-19/real-image/human-agentic-language message. Fixation-frequency on the image produced significantly higher fear perceptions, but significantly lower message-quality and message-credibility perceptions. Flu messages led to significantly …
