Metamorphosis: An Evaluation Of The Adaptation And Re-Use Potential Of Suburban Housing For Older Homeowners, Michelle Moore

Masters

Ireland’s population is ageing at a rate that is more than twice the EU average. Public policy in Ireland aims to support older persons to age-in-place. Over 80% of older adults in Ireland live in an owner-occupied home, following many decades of public policy promoting home ownership as the tenure of choice. Limited research has been undertaken on the housing adaptation options that could result in privately-owned homes being made more suitable for the evolving needs of the rapidly ageing demographic. This thesis addresses the hypothesis that, with the provision of an appropriate suite of enablers, older homeowners can be …

Electrochemical Detection Of Nitrite Based On Iron Oxide–Reduced Graphene Oxide Nanocomposite Modified Electrode In Real Water, Amira Ghezal, Zina Fredj, Ammar Al-Hamry, Marcos A. Gross, Leonardo G. Paterno, Mounir Ben Ali, Olfa Kanoun, Baljit Singh

Research Outputs: 2025-Present

This work presents a screen-printed carbon electrode (SPCE) modified with iron oxide nanoparticles-reduced graphene oxide (ION-rGO) nanocomposite for the rapid and highly sensitive determination of nitrite in real water samples. The presence of both ION and rGO on the electrode surface enhances the sensing performance compared to the unmodified SPCE by reducing the charge transfer at the electrode/electrolyte interface. Under optimized conditions, it is demonstrated that the charge-transfer resistance determined from electrochemical impedance spectroscopy (EIS) scales linearly with the logarithm of nitrite concentration. Due to its unique structure, the proposed nitrite sensor displays improved performance compared to our previous work, …

Exploring The Sustainability Of Single Use Plastics In The Biopharmaceuticals Sector: A Scoping Review Of Challenges, Opportunities And Impact, Cormac Mcmahon, Adrienne F. M. Fleming, Philip Owende, Malcolm Goggin

Articles

Single-use plastics (SUPs) are synonymous with the biopharmaceuticals sector, facilitating economies of scale, process efficiency, flexibility and sterility assurance, all with a seemingly negligible environmental footprint. Yet, in ever-tightening regulation, mandated by the Sustainable Development Goals (SDGs) and by concern for large-scale industrial impacts, the sustainability of SUP consumption is increasingly being questioned. Whilst the sector contributes to human welfare, its transition risk is unlikely to remain immune to societal pressure for more sustainable production. This paper aims to present a scoping review of the apparent contradiction between sectoral SUP adoption and the increasing importance of circularity. The approach to …

Children’S Outdoor Play Injuries: How Real Are Parental Concerns Of Danger In Outdoor Play?, Fiona Armstrong, David Gaul

Research Outputs: 2025-Present

Risky play can be defined as any play that is thrilling or exciting, involving risk of injury [Sandseter, E. B. H. (2007). Categorising risky play—How can we identify risk-taking in children's play? European Early Childhood Education Research Journal, 15(2), 237–252.]. Risky play has been associated with danger and increased risk of injury, yet there is limited evidence relating to the prevalence of injuries because of play, with existing data mainly related to home and sports-related injuries [Gilmartin, S., Barrett, M., Bennett, M., Begley, C., Ni Chroinin, C., O’Toole, P., & Blackburn, C.

Synthesising Cross-Speaker Data For Low-Resource Pathological Speech Recognition With Peft, Kesego Mokgosi, Milad Dadgar, Cathy Ennis, Robert Ross

Conference papers

Dysarthric speech recognition is essential for enhancing communication and accessibility for individuals with speech impairments, yet its development is hindered by a scarcity of robust, speaker-specific datasets. This study explores low-resource dysarthric speech recognition through cross-speaker transfer using synthetic data and parameter-efficient fine-tuning (PEFT). We integrate SpeechT5 text-to-speech (TTS) synthesis with x-vector speaker embeddings to generate speaker-specific dysarthric speech, enabling model adaptation while preserving pathological speech characteristics such as prosodic irregularities. Experiments on the TORGO dataset show that mixed cross-synthetic data with LoRA fine-tuning achieves a WER of 0.17, representing a 71.7% improvement over the standard model (0.60 WER) without …

Factor Substitution Possibilities, Labor Share Dynamics, And Inequality In An Age Of Intangibles, Adnan Velic

Articles

We examine the economy-wide degree of substitutability between intangible capital and other factor inputs in production using a large sample of advanced countries. In this context, we turn to studying the implications of intangible and tangible capital growth for labor income share dynamics. Compared to tangible capital, we find that intangible capital more strongly complements skilled labor. The analysis further indicates relative fungibility between tangible capital and a composite of intangible capital and skilled labor, in line with the rising prominence of knowledge-intensive tasks and AI-driven online platforms. The intrinsic nature of intangibles and their asymmetric effects across skilled and …

Evaluation Of Processing Conditions For The Reduction Of Electrochemical Salt Waste Using Phosphate-Based Dechlorination, Harmony Werth, Jade Beland, Paige Murray, Dave Liang, Laurel Sharpless, Jonathan Evarts, Charmayne Lonergan, Brian J. Riley, Michael Simpson, Krista Carlson

Materials Science and Engineering Faculty Research & Creative Works

Electrochemical processing of used nuclear fuel in molten chloride salts generates complex radioactive salt waste. Dechlorination of waste salt using phosphate compounds at elevated temperatures (∼600 °C) reduces the volume of material for disposal while evolving gaseous chlorine compounds that could be used to transform metallic uranium into UCl3. In this study, the effects of processing temperature, environment (air or argon), and H3PO4 precursor-to-chlorine ratio on the dechlorination efficacy of a simple alkali salt mixture (SSM) and a salt waste simulant (ERV3) were evaluated. For both salts, the highest chlorine release was concurrent with the water boiling. For the SSM, …

Socioeconomic Status And Educational Opportunities Through The Eyes Of Students And Teachers: Diverse Realities, Shared Insights, Jill Schany

Dissertations and Theses @ UNI

Sowl and Crain (2021) argue that despite recognizing the uniqueness of the place when it comes to rural demographics and needs, policies regarding education and the economy often prioritize urban areas, defining rural in opposition to urban without adequately addressing the specific needs of rural youth. Studies examining geographical disparities in educational outcomes traditionally concentrated on achievement gaps within urban and suburban areas, highlighting more startling gaps in cities with heightened racial, ethnic, and socioeconomic inequality and segregation. Literature also extensively discusses neighborhood effects on educational outcomes in densely populated regions, offering valuable insights into the distribution of educational opportunities …

Processing Of Verbal Versus Adjectival Agreement: Implications For Syntax And Psycholinguistics, Zuzanna Fuchs, Olga Parshina, Irina A. Sekerina, Maria Polinsky

Publications and Research

Linguistic theories distinguish between external and internal agreement (e.g., noun-verb agreement vs. noun-modifier agreement, the latter also known as concord) and model them using different mechanisms. While this distinction has garnered considerable attention in syntactic theory, it remains largely unexplored in experimental work. In an effort to address this gap, we conducted two studies of external/internal agreement in Russian using self-paced reading and eye-tracking while reading. We measured the response to violations generated when native speakers encounter a noun that mismatches the features on an earlier element inflected for agreement (verb, modifying adjective, and predicative adjective). Both experimental studies found …
