This research seeks to build upon previous research by showing that word embeddings may shed light on the underlying neural representation of semantic entities being acquired …

A Multi-State Look Into Early Intervention Speech-Language Pathologists’ Confidence Identifying And Diagnosing Autism, Allison Gladfelter, Adelaide Parr, Anna Cannone, Sarah O'Connor

CISLL Publications

Purpose: Although autism can be reliably diagnosed by 18 months of age, long wait times and limited access to qualified providers prevent families from obtaining timely diagnostic services. Trained speech-language pathologists (SLPs) are qualified to diagnose autism, ideally as part of a multidisciplinary team. SLPs working on early intervention (EI) teams are well-situated to help close this diagnostic wait time gap. The purpose of this survey study was to explore EI SLPs’ experiences serving autistic children, confidence in identifying and diagnosing autism, and their perceptions of barriers or facilitators to diagnostic confidence and wait times.

Method: 287 EI SLPs from …

Press Protection As Anticorruption, Zachary Reger

Texas A&M Law Review

As the partisan press of the Founding Era gave way to the commercial press of the nineteenth century, then to the professional press of the twentieth century, American journalism assumed an increasingly skeptical attitude toward governmental power. Today, the investigatory and information-spreading functions of the “fourth branch” are more important than ever to checking public corruption in a vast administrative state. At the same time, the press faces financial crisis, threatening the anticorruption interest.

This Essay evaluates three mechanisms for shoring up the corruption-fighting role of American journalism: (1) constitutional speech protections for the corporate form taken by most modern …

Faculty Research, Scholarly, and Creative Activity

It is increasingly acknowledged that high income countries do not enjoy universal drinking water coverage, with pockets of water insecurity persisting close to areas that have had high-quality, centralized water provision for half a century or more. The reasons behind this are complex, and effective ways to improve water security in these areas defy simple prescriptions. Nuanced measures that disaggregate the different facets of water insecurity are especially important as we attempt to understand and, crucially, improve water security in high-income countries.In this paper, we describe a qualitative protocol for assessing water insecurity at the household level in a study …

Moderate-Temperature Hydrothermal Treatment Removes Detectable Dna And Antibiotic Resistance Genes From Municipal Sludge While Preserving Resource Value, R Sean Norman M.Sc., Ph.D., Mirza Isanovic, Gabrielle Kartzmark, Nicole Berge

Faculty Publications

Wastewater treatment plants (WWTPs) are key reservoirs of antibiotic resistance genes (ARGs), with municipal sludge containing high bacterial densities and diverse ARGs that may spread through land application. Hydrothermal treatment (HT) is a process that inactivates pathogens and stabilizes biomass, but its performance at moderate temperatures is less understood. We evaluated HT (100°C–250°C; 2–24 h) for degrading bacterial DNA and ARGs in dewatered municipal sludge. DNA was quantified by fluorometry, bacterial presence confirmed by 16S rRNA gene PCR, and ARGs profiled by qPCR targeting 84 clinically and environmentally relevant genes. HT up to 250°C produced modest carbon densification, high solids …

Circularity And Carbon Performance Of Prefabricated Biobased Modular Systems: A Comparative Analysis Of Cases And Life Cycle Assessment Methods, Patrick Daly

Research Outputs: 2025-Present

The construction sector faces escalating pressure to reduce embodied greenhouse gas emissions while transitioning from linear material use toward circular, regenerative systems. Biobased modular wall assemblies designed for disassembly and reuse are increasingly promoted as a pathway to address both challenges; however, robust empirical comparisons with conventional construction remain limited, particularly when assessed across different life cycle assessment (LCA) methods and circularity assumptions. This paper presents a comparative, multi tool, and multi cycle LCA of prefabricated biobased modular wall systems developed within two EU research and demonstration projects (Drive 0 and Circ Reno), benchmarked against conventional external wall insulation systems …

Why Text Prevails: Vision May Undermine Multimodal Medical Decision Making, Siyuan Dai, Lunxiao Li, Kun Zhao, Eardi Lila, Paul K. Crane, Heng Huang, Dongkuan Xu, Haoteng Tang

Computer Science Faculty Publications

With the rapid progress of large language models (LLMs), advanced multimodal large language models (MLLMs) have demonstrated impressive zero-shot capabilities on vision–language tasks. In the biomedical domain, however, even state-of-the-art MLLMs struggle with basic Medical Decision Making (MDM) tasks. We investigate this limitation using two challenging datasets: (1) three-stage Alzheimer’s disease (AD) classification (normal, mild cognitive impairment, dementia), where category differences are visually subtle, and (2) MIMICCXR chest radiograph classification with 14 non–mutually exclusive conditions. Our empirical study shows that text-only reasoning consistently outperforms vision-only or vision–text settings, with multimodal inputs often performing worse than text alone. To mitigate this, …

The Evolving Landscape Of Social Education In The Uk: The Legacy Of Neoliberalism Affecting Uk Children And Those Who Support Them, And The Considerable Value Of Its Potential Counterbalance — Social Pedagogy, Robyn Kemp

Journal of Social Care

This paper examines the erosion of concern for the social and relational in the United Kingdom through four decades of neoliberal policy, and argues for social pedagogy as a principled and urgently needed counterbalance. Drawing on a career spanning public, charitable, and academic practice primarily with children in and on the edges of care, it traces how the introduction of neoliberalism under Thatcher in the 1980s — and its institutionalisation through New Public Management in the 1990s — systematically dismantled the relational, ethical, and communal foundations of work with children. The consequences are documented in stark statistical terms: rising school …

The Role Of Personality In Collegiate Athletes’ Indicators Of Performance And Injury Experiences – A Mixed Methods Study, Allison Traub

Doctoral Dissertations and Projects

This mixed methods study explores the impact of collegiate athletes' indicators of personality traits as attributed to athletic performance, injury experiences, and sport identity. Sports often emphasize physical abilities, yet the role of personality is equally significant—though it has received comparatively little attention in psychological research. This research addresses such a gap through examining how personality traits shape athletes’ competitive behavior along with coping strategies. The traits are defined within the 16 Personalities framework using Myers-Briggs Type Indicator (MBTI) and how it influences just how athletes recover. This research will explore research questions such as how personality affects college athletes' …
