The Role Of Artificial Intelligence In Marine Pollution: A Review, Safaa A. Abdel Ghani, Sahar W. M. Hassan, Aida H. Shobier

Blue Economy

Marine pollution represents a significant threat to the sustainable use of ocean resources and is increasing globally. Consequently, multidimensional and sustainable ocean governance frameworks have placed growing emphasis on the prevention, reduction, and elimination of marine pollution. In recent years, artificial intelligence (AI) has been increasingly adopted as an effective tool for monitoring, assessing, and managing marine pollution. This review aimed to highlight the role of artificial intelligence in addressing marine pollution. The efforts of scientists in employing and leveraging the advantages of AI to tackle the issue of marine pollution were examined. It was found that AI, supported by …

The Second Prophecy Of Mandos: Eschatology, Mythic Sources, And Editorial Choices In Tolkien’S Legendarium, Paolo Pizzimento Dr.

Journal of Tolkien Research

This article examines the development and significance of the Second Prophecy of Mandos within J.R.R. Tolkien’s legendarium. Through an analysis of Tolkien’s published works and posthumously edited texts, the study traces the evolution of the prophecy from its earliest formulations in The Book of Lost Tales to its later iterations in the Quenta Silmarillion tradition. Particular attention is devoted to the editorial decision by Christopher Tolkien to omit the prophecy from the 1977 publication of The Silmarillion, assessing both the philological and interpretative factors that may have influenced this choice. The essay further investigates Tolkien’s conceptualization of eschatology …

Visualizing Ozone Pollution In The Denver Metro Area Using A Bioindicator Garden, Ella K. Mathews, Hillary Hamann, Julie Morris, Erica L. Larson

DU Undergraduate Research Journal Archive

Since the industrial revolution, widespread fossil fuel combustion has significantly increased atmospheric pollution. The combustion of fossil fuels releases nitrogen oxides (NOx) and volatile organic compounds (VOCs), which form tropospheric (ground-level) ozone when exposed to sunlight. Ozone directly harms plants by disrupting their ability to absorb carbon dioxide, release oxygen, and carry out photosynthesis. Bioindicator species are plants that have visible responses to environmental conditions, such as ozone, and can act as “canaries in the coal mine,” indicating the health of their environment. In this study, we used a garden of ozone bioindicator species (ozone garden) as a cost-effective tool …

King Of The Jungle: Comparative Analysis Of The Geopolitical Narratives Surrounding Fordlandia And A Proposed Resort Park In El Mirador, Rachel Jaeger

DU Undergraduate Research Journal Archive

Environmental geopolitics is a field of study in which narratives about the environment are analyzed to reveal the underlying motivations and objectives they support. Using Shannon O’Lear’s (2020) framework of environmental geopolitics, I conduct a comparative analysis of the narratives surrounding two distinct development projects: Henry Ford’s historical company town in the Brazilian Amazon, Fordlandia, and a proposed ecotourism resort park in El Mirador, Guatemala. Analysis of Fordlandia reveals a narrative of American frontierism and a man-versus-nature perspective that served to paint the environment as belligerent and thereby justify corporate control and Indigenous assimilation. Narratives surrounding El Mirador differ, representing …

Greenspace Access In The Denver Metro Region: Historical Housing Policy Impact On Modern Greenspace Distribution, Brody Petig, Susan Dagget

DU Undergraduate Research Journal Archive

Access to safe, high quality, urban green spaces is widely recognized as a determinant for physical health, mental well-being, and social cohesion. Existing literature has demonstrated that race, age, gender, and socioeconomic status frequently dictate the allocation of resources and shape disparities in access to greenspace. These disparities are also often reflective of historical housing policy and zoning decisions. This paper examines greenspace access in the Denver Metro Region (DMR) and the City and County of Denver (CCD) through a social justice lens, with particular attention to the relationship between historical housing policy and contemporary trends in greenspace distribution and …

Urban Removal: The Long-Term Impacts Of The Displacement Of Denver’S Auraria Neighborhood, Sophia Krout, Reginald A. Byron

DU Undergraduate Research Journal Archive

In the early 1970s, the Auraria Center for Higher Education was developed, displacing a well-established Denver Latino neighborhood, which encompassed a 38-block district at the time, including 155 families, 49 single individuals, and 237 businesses, and clearing the way for the establishment of the Metropolitan State University of Denver, the University of Colorado Denver, and Denver Community College. The implementation of remedial measures for the displacement has fallen short of meeting the needs of displaced residents. The residents were promised affordable education through a program named the Displaced Aurarian Scholarship, which has similarly stated intentions of improving the educational attainment …

Patron-Client Relationship Undermines Sustainable Fishery Governance: A Case Of Small-Scale Fishing Certification In Sulawesi, Indonesia, Desiree Simandjuntak

Forest and Society

One of the ways market-based fishery governance attempts to boost sustainable fishing is through economic incentive. Offered as an above-market price to producers, it is commonly practiced in seafood certification to encourage sustainable and equitable production. However, certification is mainly inaccessible to small-scale fishers who are typically tied to pre-existing patron-client relationship, particularly those from developing economies. This study analyzes the extent to which economic incentive can benefit small-scale fishers amidst the intricate power imbalance in producer community. Based on a ten-month ethnography study in Sulawesi, Indonesia, it finds that prevalent patronage impedes participating fishers' income as it is affected …

Forecasting Interborough Express Ridership Using Network-Based Station Typologies And Direct Demand Models, Fomba Kassoh

Student Theses

Forecasting ridership for new transit infrastructure is difficult in the absence of observed outcomes, particularly under domain shift between an existing system and a proposed corridor. This study develops a station-level direct demand modeling (DDM) framework to forecast average weekday ridership for the proposed Interborough Express (IBX) in New York City — a 14-mile circumferential rapid transit corridor connecting Brooklyn and Queens. The approach pairs unsupervised learning with supervised estimation in a common feature space defined by transit service, accessibility, and built-environment characteristics. K-means clustering identifies latent station typologies (node–place regimes), and IBX stations are projected into this topology to …

Bridging The Justice Gap: A Comparative Study Of Legal Aid Marketing In Canada, Australia, And The United States, Farah O. Haq

Student Theses and Dissertations

Access to justice remains a central challenge across legal systems, particularly for immigrants and refugees, Indigenous communities, and survivors of domestic violence. While legal aid organizations play a critical role in bridging this gap, their effectiveness increasingly depends on how clearly and compassionately they communicate legal information online to their target audience. This thesis conducts a comparative content analysis of nine nonprofit legal aid organizations in the United States, Canada, and Australia, three countries united by a common law tradition but divided by the communication barriers their communities face, examining 180 social media posts and nine websites through the lens …

A Political Ecology Of The Orang Rimba's Struggle And Existence In Jambi, Indonesia, Aditya Dipta Anindita, Arya Hadi Dharmawan, Soeryo Adiwibowo, Didik Suharjito

Forest and Society

Since the 1970s, forest conversion in the name of development has encroached upon the living spaces of the Orang Rimba, a forest-dwelling indigenous group in Jambi Province, Indonesia. Some of the forest areas, which serve as the cultural and livelihood foundation for this hunter-gatherer community, have been transformed into transmigrant settlements and oil palm plantations, while the remaining forests were designated as a National Park in 2000. Although they still have access to the national park, many Orang Rimba have built their livelihoods among the oil palm trees—not as owners or workers, but believing that these lands are their ancestral …

From Double Absence To Double Presence: Video-Selfie As Empowerment In A Multicultural Italian Classroom, Maria Ranieri, Ilaria Bucciarelli, Giulia Cuozzo

Journal of Media Literacy Education Pre-Prints

This paper examines the video-selfie as a tool for empowerment in multicultural secondary school classrooms. We draw on data from the European ICME project, focusing on a vocational secondary school in Italy, where 17 of 18 first-year students – approximately half of whom had migration backgrounds – produced short videos presenting themselves through personally meaningful objects. Students then participated in a structured reflection activity after watching each other's videos in class. We combine three theoretical frameworks: critical media literacy, identity and self-representation studies, and Mezirow's transformative learning theory. Our argument is that the video selfie empowers in multiple ways: it …

Hidden In Plain Sight: The Role Of Belonging In Shaping Pre-Service Teachers’ Motivations & Practices In A Paraprofessional-To-Teacher Pathway, Julie Sidarous Dr., Douglas Van Dyke Dr.

i.e.: inquiry in education

As school districts face persistent teacher shortages, paraprofessionals and school staff remain an untapped resource with immense potential. The purpose of this study was to explore the distinct benefits that school employees bring to the teaching profession when transitioning into roles as teachers of record. To deeply understand candidates' stories, this qualitative study employed Interpretive Phenomenological Analysis (IPA) to examine how preservice teacher candidates make sense of their own lived experiences. The findings reveal five key advantages these transitioning educators provide: deep community connections, practical institutional knowledge, resilience in high-need schools, expertise supporting non-traditional learners, and a profound desire to …

Belonging As The Bedrock Of Learning, Gloria Mcdaniel-Hall, Nina Weisling

i.e.: inquiry in education

The reasons why we teach are intensely personal. We give our hearts and souls to “the work,” though it is so much more than work to us. It is a calling, felt deep in our souls, to correct wrongs, to bend the “arc of the moral universe” all the way to justice, to realize the dreams that have been deferred at best and stamped out and denied at worst. Because at the core of each day, we find humans, students, families, and colleagues who are inherently worthy of learning, loving, and living a fulfilling life. Yet, for far too many …

After Meat: Ruin, Decomposition, And The Epistemic Collapse Of Industrial Food Systems, Alexandra Kenefick

Dublin Gastronomy Symposium

The contemporary crisis of industrial meat is typically framed in environmental, ethical, or technological terms. This paper argues instead that the crisis is fundamentally epistemic, exposing the conceptual limits of modern food systems organized around abstraction, purification, efficiency, and control. Drawing on critical theories of modernity, political ecology, and design, it reframes meat not as food but as a designed industrial artefact. Through the lens of ruin, industrial breakdown is read as material disclosure, rendering visible the violences, dependencies, and exclusions that sustained modern abundance. Against technological solutionism and post-meat futurism, the paper develops decomposition as an alternative epistemic and …

Migration And Settlement: Nation, Diaspora, And Culinary Geographies In Izmir’S Culinary Culture, Betül Öztürk

Dublin Gastronomy Symposium

The study explores the historical formation of Izmir as a port city shaped by waves of migration, examining how these dynamics contributed to the emergence of a hybrid culinary culture. The present study draws on historical sources and literature on migration to trace Izmir’s transformation from a small Ottoman settlement to a cosmopolitan Mediterranean city. The study highlights the role of diasporic communities including Rums, Sephardic Jews, Armenians, Levantines and later internal migrants in shaping daily life. The manner in which cohabitation patterns, neighbourhood-based settlements, and shared economic spaces have served to facilitate continuous cultural interaction among ethnic minorities is …

Burning Bridges? Conflicting Advice In Early Job Reneging And Implications For Practice, Amanda Leigh Bisson, Jo-Louise Huq

Engaged Management ReView

The time between early talent offers and students’ graduation dates is increasing. Although students are strongly encouraged by their universities not to renege on accepted early job offers, reneging is not uncommon in practice. In this paper, we explore how students approach the reneging decision, specifically examining the questions they ask and the advice they receive from peers and professionals. Using an interpretivist approach and reflective thematic analysis, we analyzed 25 Reddit posts by accounting students navigating reneges. Our findings offer novel insights into the student experience and the advice students are receiving from social network contacts. We find that …

Bonding Through Boucherie: Strengthening Social Ties Through Butchery, Evelyn Lambeth

Dublin Gastronomy Symposium

“La boucherie de quartier” is a Cajun phrase referring to a neighbourhood pig slaughter. One such annual event, the Lâche Pas Boucherie in southern Louisiana, brings multiple generations and many traditions together with the goal of sharing and celebrating music, food and culture. Boudin, crackling, andouille sausage, and hogshead cheese are but a few of the unique offerings from this melting pot of shared flavours. I was born and raised in southern Louisiana but rarely appreciated the novelty of Cajun cuisine until I moved to Australia. The flavours and spices of my former home add a certain piquancy that is …

Hands To Work, Hearts To Hope: Mutual Aid And The Re- Embodiment Of Care In An Age Of Crisis, April Mcgreger

Dublin Gastronomy Symposium

Mutual aid and charity groups often pay attention to the tangible results of their work for the groups serviced but too often ignore the benefits of the work to the workers themselves. Using the experience of the People’s Kitchen in Philadelphia, the author details the diversity of experiences of kitchen workers and some of the benefits of volunteering. Methodology uses surveys and self- ethnology and contributes to new areas of research.

Toddy, Tea, And Tapioca: Food, Famine, And The Moral Reordering Of Public Space In Malabar (Kerala), 1900- 1965, Mallory Rose Cerkleski

Dublin Gastronomy Symposium

This paper examines how public food and drink spaces in early twentieth-century Malabar functioned as critical infrastructures of everyday subsistence as well as sociability. It argues that toddy shops, beyond sites of intoxication, might have provided low-cost nutrition, informal credit, and cross-caste interaction for segments of the labouring poor. Colonial excise policies and temperance movements progressively narrowed these spaces, contributing to the rise of tea shops aligned with reformist ideals of respectable public consumption. While tea shops fostered political discussion and vernacular modernity, they could have been less reliable as nutritional buffers, especially during the food crises of the 1940s. …

The Pub “Crisis” And The Future Of Alcohol-Related “Third Spaces”: A Cross-National Survey, Perry Share

Dublin Gastronomy Symposium

Across a range of countries, pubs and cognate drinking venues are shrinking in number and being reimagined in function. This paper examines the contemporary “pub crisis” in Ireland, Britain, Hungary, Japan, South Korea, the Netherlands and Australia, drawing on academic, policy, media and industry materials gathered during late 2025 and early 2026. It argues that, despite different national histories and drinking cultures, similar pressures recur: rising costs, labour shortages, changing alcohol consumption, weakened after-work drinking norms, and redevelopment pressures, with rural and peripheral areas often most exposed. The paper treats pubs not simply as licensed businesses, but as contested forms …

Projected U.S. Cardiovascular Disease Burden From Heat Exposure For Future Greenhouse Gas Scenarios, Gokul Parmeswaran, Sai Rahul Ponnana, Santosh Kumar Sirasapalli, Niketh Surya, Tong Zhang, Zhuo Chen, Jean-Eudes Dazard, Salil V. Deo, Sanjay Rajagopalan

Importance: Climate change may reverse decades of improvements in cardiovascular disease (CVD) mortality in the US; however, comprehensive regional projections of heat-related CVD burden in the US are unavailable. Objective: To use the county-level observed (2010-2016) heat-related CVD burden in the US to obtain the projected rates through 2050 according to the mean (shared socioeconomic pathway [SSP] 2-4.5) and high (SSP5-8.5) greenhouse gas (GHG) emission pathways. Design, Setting, and Participants: This cross-sectional ecological analysis used county-level summary data including all counties in the contiguous US from 2010 through 2016 as baseline data with projections to 2030 and 2050 under SSP …

Do Rural-Urban Disparities Translate Into Nursing Complexity At Hospital Admission? Evidence From A Single Tertiary-Care Pediatric Hospital In Italy, Manuele Cesare, Gianfranco Damiani, Gloria Anderson, Jessica Preziosi, Rosemary Frasso, Leonardo Villani, Nursing And Public Health Group, Vittorio Maio, Antonello Cocchieri

College of Population Health Faculty Papers

BACKGROUND/OBJECTIVES: Rural-urban disparities are well documented in pediatric healthcare, influencing access, service organization, and outcomes. However, whether these differences extend to the domain of nursing care remains unclear. This study examined the association between degree of urbanization and nursing complexity among children admitted to a single tertiary-care pediatric hospital, comparing clinical, organizational, and nursing characteristics across geographic groups.

METHODS: Routinely collected electronic nursing documentation and hospital administrative records were retrospectively examined in a tertiary-care pediatric hospital in Rome, Italy. Children aged 2 to < 18 years were consecutively included. Degree of urbanization was defined using the ISTAT-derived DEGURBA classification. The study outcome for nursing complexity corresponded to the number of nursing diagnoses documented at hospital admission. Descriptive analyses and a multivariable negative binomial regression model assessed the association between urbanization and nursing complexity, adjusting for age, sex, DRG weight, number of medical diagnoses, and chronic conditions.

RESULTS: Among 1652 pediatric hospitalizations, those from rural areas showed a higher clinical burden, with significantly higher …

Crime, Economic Forces And Trucks Crossings In The Us–Mexico Border Region, René Cabral, André Varella Mollick, Eduardo Saucedo

School of Economics and Finance Faculty Publications

We investigate northbound loaded truck crossings from Mexico to the United States between 2015 and 2023. A weaker peso, exports and US industrial production positively affect loaded containers. Truck robberies at the municipal level show no statistically significant relationship with truck loadings, whereas truck robberies at the national and state levels present a negative, persistent association. Results suggest that Mexico–US trade would benefit from lower average Mexican crime rates. In addition to comparing Texas with other border states, this study documents the role of crime specific to the transportation sector as a negative relevant driver of truck crossings to the …

Does Modernisation Of Traditional Dishes Lead To Their Destruction? The Case Of Baklava, Banu Özden

Dublin Gastronomy Symposium

The modernisation of traditional dishes presents a tension between culinary creativity and the preservation of cultural heritage. Using baklava as a single case study, this paper investigates whether such modernisation leads to the destruction of traditional foodways. Drawing on a qualitative study with seven Turkish chefs, the research finds that innovation does not inherently threaten baklava’s identity. Instead, preservation depends on maintaining the dish’s essential technique—multiple layers of paper-thin pastry—while allowing flexibility in presentation and narrative framing. Participants agreed that baklava’s strong cultural foundation renders it resilient against fusion experiments and deconstructed forms, provided its core qualities remain intact. However, …

What My Grandma Ate, What My Grandma Wrote: Culinary Memory, Migration, And Changing Foodways In A Cretan–Turkish Household, Sedef Özgönül Donuktan

Dublin Gastronomy Symposium

This paper explores the difference between daily eating habits (what is “eaten”) and handwritten recipe notebooks (what is “written”) within a Cretan-Turkish kinship network influenced by migration and resettlement. By combining oral history interviews with five women and analysing 242 notebook recipes, the study shows that these handwritten books are not just passive records of daily meals. Instead, they serve as selective domestic archives shaped by a “festive bias,” standardisation, and social value. The research indicates that while routine meals (such as stews) depend on embodied, unrecorded knowledge, the notebooks mainly contain special dough recipes using modern industrial ingredients like …
