Orthographic Support For Verb Identification In Typically Developing Three-Year-Old Children, Grace T. Clark, Christina Reuterskiold

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Children, as young as four years of age, have demonstrated enhanced noun learning when presented with orthographic representations during word learning tasks. This study sought to determine if three-year-old typically developing children would demonstrate an orthographic facilitation effect during an asynchronous computer-based verb learning task. One-hundred ten children were taught 8 novel verbs by presenting videos of novel actions paired with novel labels in sentence frames. Four novel verbs were taught with orthographic support present and four were taught without orthographic support. Participants were exposed to the words a total of two times and then given a post-test to assess …

Verbs Are Tricky: Does Orthography Support Verb Identification In Typically Developing Children Ages 3–8?, Grace T. Clark, Gabriella Pesantes, Madison Skibicki

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Purpose:
This study examined whether orthographic representations—seeing a printed word while hearing it—facilitate verb identification accuracy in typically developing children and whether developmental or literacy factors modulate this effect.

Method:
One hundred eight English-speaking children ages 3–8 years (M = 5.86) completed a web-based verb learning task through Children Helping Science. Participants were randomly assigned to an orthography-present or orthography-absent condition while learning six novel verbs paired with dynamic action videos. Accuracy during a two-alternative forced-choice test was coded from parent-verified pointing responses. Caregivers completed a literacy interest questionnaire, and children completed a letter–sound correspondence task. Multilevel logistic regression …

Chatbot Assessment: Best Practices For Artificial Intelligence In The Library, Michelle Ehrenpreis, John P. Delooper

Publications and Research

In November 2019, the Leonard Lief Library implemented Ivy.ai, a proprietary chatbot on its website. This implementation was the first academic library installation of a vendor-supplied chatbot to be discussed in the professional literature. This chatbot functioned as a new tool that assisted users seeking information from the library website. User questions provided insight to the authors about the kinds of topics students searched for via the library website. In April 2023, the chatbot’s vendor began using OpenAI’s ChatGPT Application Programming Interface (API) to improve the chatbot’s functionality. This change, from a rules-based chatbot system to a transformer model, enhanced …

Civic Participation And Meaning In Life: Similarities And Differences Across Diverse Youth, Yue Ni, G. John Geldhof, Richard A. Settersten, Shauna L. Tominey

Psychology Faculty Publications and Presentations

Civic engagement is an important component of youth thriving, but prior research—focused primarily on political engagement—has found a “civic engagement gap” between youth with marginalized identities and those with privileged social identities. Research is needed to understand youth involvement in other civic activities, patterns of disparities, and any implications of these differences for youth well-being. In this study, we examined differences in community service activities, political activities, and expressive activities and their relationships with meaning in life 2 years later across 11 groups of 1,088 adolescents defined by intersections of race/ethnicity, socioeconomic status, and nativity. Findings reveal great diversity in …

A Case Of Navigating Autism And Atypical Rashes In Dermatology Practice., Benjamin S Kahn, Kathleen Ward, Nedyalko Ivanov, Marcus Goodman

PCOM Scholarly Works

A 4-year-old nonverbal autistic female presented to the clinic with a 3-month history of a persistent, inflamed papular rash, which was violaceous to skin-toned, verrucous, and dome-shaped with crateriform ulcerations on an erythematous base localized in the perianal region. A dermatologic condition with these characteristics, location, and demographic warrants a thorough workup, physical exam, and broad differential diagnosis. The clinical appearance of these lesions can mimic many cutaneous conditions in this age group and requires careful attention for potential signs of abuse. As demonstrated in our case, with a comprehensive patient history, a biopsy, and a culture of the lesions, …

Myo/Nog cells play a pivotal role in ocular development and demonstrate a rapid response to stress and injury. This study investigates their behavior and distribution in a murine model of retinitis pigmentosa, specifically in C3H/HeJ mice, which exhibit photoreceptor degeneration due to a homozygous mutation in the Pde6brd1 gene. Retinal samples from C3H/HeJ and C57BL/6J mice were analyzed at postnatal weeks 2.5 to 6 using hematoxylin and eosin staining, immunofluorescence for brain-specific angiogenesis inhibitor 1 (BAI1) expressed in Myo/Nog cells, and TUNEL labeling for apoptotic cell detection. The results demonstrated a progressive thinning of the outer nuclear layer (ONL) in …

Infections With Chlamydia Pneumoniae And Sars-Cov-2 And Alzheimer's Disease Pathogenesis, Alexa Romanella, Maegan Mccall, Rachel Corwin, Alaha Abdul Faruq, Emily Lingo, Sanya Bhambhani, Christine J. Hammond, Brian J. Balin

PCOM Scholarly Works

INTRODUCTION: Alzheimer's disease (AD) is the most prevalent neurodegenerative disease in the world, but our understanding of causation is still lacking. A current evidence-based hypothesis proposes that certain infectious agents initiate the neurodegeneration consistent with AD. Two infectious agents correlated to AD pathogenesis are Chlamydia pneumoniae (Cpn), a respiratory obligate intracellular bacterium, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the coronavirus responsible for the COVID-19 pandemic. Both organisms may predispose susceptible populations to disease manifestations, such as AD.

METHODS: This review focused on peer-reviewed original research and review articles evaluating the potential association of Cpn and SARS-CoV-2 with AD. …

The Unenforceable Indian Trust, Ezra Rosser

Scholarly Articles in Law Reviews & Journals

This Essay explores the Indian trust relationship in light of recent decisions, especially Arizona v. Navajo Nation, that severely limit the judicial enforcement of federal trust responsibilities. Given the built-in tension between the trust responsibility and self-determination, periodic reassessment of the role and power of the Indian trust is perhaps inevitable. The Supreme Court's attack on meaningful enforcement of the trust responsibility is deeply problematic in that it puts tribes in the position of getting neither the benefits of a special Indian trust nor those principles that are supposed to govern trusts in general. But the Court is not …

Institutions And Economic Development, Ezra Rosser

Scholarly Articles in Law Reviews & Journals

INTRODUCTION: Though forty years have passed since the American Indian Law Review published Economic Development in Indian Country: What Are the Questions? by Professor Frank Pommersheim, many of the same challenges and questions about economic development remain. This brief Essay looks back at Pommersheim’s work, surveys the state of scholarship on economic development today, and offers a few ideas about the future of such work. To this day, economic development remains a backwater among law professors compared to sexier topics like criminal jurisdiction, civil authority over nonIndians, and whatever is the most recent opinion from the U.S. Supreme Court. But …

Miao, Caio Matias, Kevin J. Hines, Christopher T T. Skidmore, Michael R. Sperling, Joseph I Tracy, Ashwini Sharan, Chengyuan Wu

Department of Neurosurgery Faculty Papers

OBJECTIVE: Temporal lobe epilepsy (TLE) is a common form of drug-resistant epilepsy often treated with surgical interventions, including laser interstitial thermal therapy (LITT). However, patient-specific factors influencing LITT outcomes remain unclear. This retrospective study aimed to identify pre-operative resting-state functional MRI (rs-fMRI) patterns associated with seizure freedom following LITT in mesial TLE.

METHODS: We analyzed rs-fMRI data from 28 patients with mesial TLE who underwent LITT, classifying them into seizure-free (SF) and not seizure-free (NSF) groups based on 12-month post-operative outcomes. Independent component analysis (ICA) was used to identify subject-specific brain networks, and generalized linear models (GLM) were employed to …

Securitization Of African Migrants In Europe And North America, Chick Edmond

Political Science & Geography Faculty Publications

The securitization of African migrants in Europe and North America refers to the framing of immigrants as an existential security threat rather than a socioeconomic or humanitarian concerns. This discourse driven by political rhetoric, media narratives, and policy measures, often depict African migrants as risks to national security, cultural identity, and economic stability. Governments in host countries employ stringent border controls, detention and deportation policies often justified by counterterrorism and crime prevention frameworks. However, critics argue that securitization exacerbates xenophobia, violates human rights, and fails to address root causes of migration, such as conflict, poverty, and climate change. This paper …

Do Adhd Symptoms Enhance College Students’ Creativity And Entrepreneurial Self-Efficacy?, Jorge Sebastian Montesinos

Dissertations and Theses @ UNI

Despite years of research focused on impairment, it is possible that attention deficit/hyperactivity disorder (ADHD) may be beneficial in some ways. Past studies have analyzed ADHD’s potential benefits to creativity and entrepreneurship, but the majority have either been underpowered or have had mixed results. In an attempt to add clarity to these potential ADHD-related strengths, the present study explored the relation between symptoms of ADHD, creative achievement, and entrepreneurial self-efficacy (ESE). The current study was a survey of emerging adult college students from multiple U.S. universities. The purpose of this study was to explore relations between symptoms of ADHD and …

Sex Work Patterns Among Transgender And Gender Diverse People: A Latent Class Analysis, Madeline Stenersen, Anjum Umrani, Irelan Fricke, Jessica L. Zemlak

College of Nursing Faculty Research and Publications

Sex work is a diverse profession encompassing a broad range of people, and services. Though overrepresented in sex work communities, transgender and gender diverse (TGD) individuals are underrepresented in sex work literature. Further, sex work literature continues to underrepresent the heterogeneity evident in the sex work community and the practices that occur within it. The present study utilized data from the 2015 United States Transgender Survey (USTS) to conduct a latent class analysis (LCA) to identify patterns of different types of sex work among TGD adults (N = 2,153) and understand the demographic characteristics associated with engagement in different types …

Spinosad is a widely used insecticide effective in controlling Aedes aegypti populations, but the molecular mechanisms underlying resistance remain poorly understood. This study explores the role of a serine protease, AeaSP (AAEL002624), in the potential detoxification ability of spinosad. Our results showed the crude protein of Ae. aegypti degraded approximately 48% of spinosad in vitro within 1 h; based on our previous research, AeaSP was believed to be potentially involved in the degradation of spinosad. Subsequently, AeaSP was recombinantly expressed in vitro, and its enzymatic activity was tested using BAEE as a substrate, with a Michaelis constant (KM) of 0.88 …

Prosecutorial Reform And The Myth Of Individualized Enforcement, Justin Murray

Articles & Chapters

The American prosecutor’s legitimacy faces unprecedented challenges. A new wave of reformist prosecutors has risen to power promising to transform the criminal justice system from within, sparking fierce backlash from defenders of the prosecutorial status quo. Central to this conflict is a debate over the nature of prosecutorial discretion, influenced by a set of claims and assumptions that this Article terms the myth of individualized enforcement. This myth posits that prosecutors base discretionary decisions on case-specific facts and equitable circumstances rather than generalizable criteria or categorical nonenforcement practices, such as the policies some reformist prosecutors have adopted that disfavor prosecuting …

Echocardiography (ECHO) is essential for cardiac assessments, but its video quality and interpretation heavily rely on manual expertise, leading to inconsistent results from clinical and portable devices. ECHO video generation offers a solution by improving automated monitoring through synthetic data and generating high-quality videos from routine health data. However, existing models often face high computational costs, slow inference, and rely on complex conditional prompts that require experts' annotations. To address these challenges, we propose ECHOPulse, an ECG-conditioned ECHO video generation model. ECHOPulse introduces two key advancements: (1) it accelerates ECHO video generation by leveraging VQ-VAE tokenization and masked visual token …

The current study examined the psychometric properties of the GAD-7 among undergraduate students from a public midwestern university (n = 582; M = 19.0 +/- 1.0 years old; 79.4% women; 81.6% White) who completed the GAD-7, State-Trait Anxiety Inventory-Trait subscale (STAI-T), and Behavioral Inhibition and Activation Scale-Reward subscale (BIAS-R). The psychometric properties of two GAD-7 models were examined: a one-factor model, equivalent to a single total score, and a two-factor model, including cognitive-emotional and somatic …

Renewal Of Cocaine Seeking Using Social And Nonsocial Contextual Stimuli, Bree A. Humburg, Michael T. Bardo

Psychology Faculty Publications

Rationale Various nonsocial cues have been used as stimuli to examine the contextual control of drug seeking behavior, but little is known about the role of social stimuli.

Objectives This study determined if renewal of cocaine seeking is differentially controlled using a context consisting of either a social peer and/or house light illumination.

Methods In Experiment 1, male and female rats trained to self-administer cocaine in the presence of a same-sex social peer and house light illumination (context A). Following self-administration, rats were randomly assigned to either an AAA (control) or ABA (renewal) group for extinction. For AAA rats, extinction …

Psychology Faculty Publications

Contemporary affective neuroscience perspectives consider possible trade-offs of neural attunement to social cues for adolescent development. Integrating these perspectives with interpersonal theories emphasizing robust belonging needs during adolescence, this study examined whether exposure to naturally occurring interpersonal stressors was differentially associated with loneliness and depression contingent on adolescent girls' neural sensitivity to cues indicating social threat (non-belonging) vs. reward (belonging). Eighty-six adolescent girls (M_age = 16.31, SD =. 84; 66.3% White) completed a social feedback task during an fMRI scan and reported on their loneliness and depression. Elevated interpersonal stress exposure was associated with more depression in girls who …
