Federal, state, tribal, or local entities in the United States issue fish consumption advisories (FCAs) as guidance for safer consumption of locally caught fish containing contaminants. Fish consumption advisories have been developed for commonly detected compounds such as mercury and polychlorinated biphenyls. The existing national guidance does not specifically address the unique challenges associated with bioaccumulation and consumption risk related to per- and polyfluoroalkyl substances (PFAS). As a result, several states have derived their own PFAS-related consumption guidelines, many of which focus on one frequently detected PFAS, known as perfluorooctane sulfonic acid (PFOS). However, there can be significant variation between …

Effect Of Nutrient Reductions On Dissolved Oxygen And Ph: A Case Study Of Narragansett Bay, Hongjie Wang, Daniel L. Codiga, Heather Stoffel, Candace A. Oviatt, Kristin Huizenga, Jason Grear

Graduate School of Oceanography Faculty Publications

To assess the consequences of nutrient reduction strategies on water quality under climate change, we investigated the long-term dynamics of dissolved oxygen (DO) and pH in Narragansett Bay (NB), a warming urbanized estuary in Rhode Island, where nitrogen loads have declined due to extensive wastewater treatment plant upgrades. We use 15 years (January 2005-December 2019) of measurements from the Narragansett Bay Fixed Site Monitoring network. Nutrient-enhanced phytoplankton growth can increase DO in the upper water column while subsequent respiration can reduce water column DO and enhance bottom water acidification, and vice-versa. We observed significant decreases in surface DO levels, concurrent …

Bioconcentration Of Per- And Polyfluoroalkyl Substances And Precursors In Fathead Minnow Tissues Environmentally Exposed To Aqueous Film-Forming Foam–Contaminated Waters, Nicholas I. Hill, Jitka Becanova, Simon Vojta, Larry A. Barber, Denis R. Leblanc, Alan M. Vajda, Heidi M. Pickard, Rainer Lohmann

Graduate School of Oceanography Faculty Publications

Exposure to per- and polyfluoroalkyl substances (PFAS) has been associated with toxicity in wildlife and negative health effects in humans. Decades of fire training activity at Joint Base Cape Cod (MA, USA) incorporated the use of aqueous film-forming foam (AFFF), which resulted in long-term PFAS contamination of sediments, groundwater, and hydrologically connected surface waters. To explore the bioconcentration potential of PFAS in complex environmental mixtures, a mobile laboratory was established to evaluate the bioconcentration of PFAS from AFFF-impacted groundwater by flow-through design. Fathead minnows (n = 24) were exposed to PFAS in groundwater over a 21-day period and tissue-specific …

De-Risking Pretreatment Of Microalgae To Produce Fuels And Chemical Co-Products, Jacob S. Kruger, Skylar Schutter, Eric P. Knoshaug, Bonnie Panczak, Hannah Alt, Alicia Sowell, Stafanie Van Wychen, Matthew Fowler, Kyoko Hirayama, Anuj Thakkar, Sandeep Kumar

Civil & Environmental Engineering Faculty Publications

Conversion of microalgae to renewable fuels and chemical co-products by pretreating and fractionation holds promise as an algal biorefinery concept, but a better understanding of the pretreatment performance as a function of algae strain and composition is necessary to de-risk algae conversion operations. Similarly, there are few examples of algae pretreatment at scales larger than the bench scale. This work aims to de-risk algal biorefinery operations by evaluating the pretreatment performance across nine different microalgae samples and five different pretreatment methods at small (5 mL) scale and further de-risk the operation by scaling pretreatment for one species to the 80 …

Contribution Of High Turbidity To Tidal Dynamics In A Curved Channel In Zhoushan Islands, China, Li Li, Fangzhou Shen, Zhiguo He, Gangfeng Ma, Jiachen Wang, Kailong Huangfu

Civil & Environmental Engineering Faculty Publications

The curved tidal channel, Luotou Deep-water Navigational Channel, is the main channel of the Ningbo Zhoushan Port, which is ranked first in the world. Tidal dynamics in the channel are spatially and temporally asymmetric. In this study, the three-dimensional tidal dynamics in the channel were analyzed using field data and simulated using FVCOM. The results show that the tides in the channel flood/ebb along the northern/southern bank near the bottom/surface layer and these asymmetries are due to the imbalanced Coriolis force, centrifugal force, sea-level gradient, and density gradient. Residual current velocity peaks (0.7 m/s) in the middle of the channel …

Kinesiology Faculty Publications

There is a relationship between acute bouts of aerobic exercise and cognition in adults, yet the exact nature of this relationship remains unclear. The current pilot study aims to investigate how different modes of cycling (active-assisted cycling vs recumbent cycling) at different moderate-to-vigorous physical activity (MVPA) intensity levels (prescribed 65–70% Heart Rate Max and self-selected 12–13 Rate of Perceived Exertion) modulate neurocognitive, and behavioral markers of cognition in healthy older adults. A sample of 10 adults (aged 50–74 years) participated in baseline (no exercise), active-assisted, and recumbent cycling interventions at different intensity levels. The P3 event-related potential (ERP), a neural …

Reclaiming Black Spirit: Redefining Social Justice Leadership With And For Black Youth In Jesuit Secondary Schools, Jeremy Divinity

LMU Theses and Dissertations

There were contradictions from the beginning regarding Jesuit education’s mission of faith, which does justice and supports African American male students. Limited research examined the experiences of African American males attending Jesuit secondary schools and their perceived support from Jesuit school leadership in ensuring they had increased feelings of belonging, inclusion, and culture through social justice efforts. In order to address this gap, this qualitative hermeneutic phenomenological study centers on the lived experiences of African American male alumni in Jesuit secondary schools regarding social justice leadership and how they make meaning of their racialized and gendered experiences while attending a …

Opportunities Out Of Challenges In Dental Education: Two Deans’ Perspectives, Clark M. Stanford Dds, Phd, Mha, David Johnsen Dds, Ms

Journal of the American College of Dentists

Addressing the challenges and creating opportunities in dental education requires a multifaceted approach involving curriculum innovation, technological integration, financial support, and mental health resources. Educational institutions must continue to work collaboratively with stakeholders, including government bodies, private sectors, and professional organizations, to develop sustainable solutions. We recognize this will take a multiprong approach. Dentists are great at problem-solving, and we are confident dental education will remain relevant, accessible, and of the highest quality, ultimately leading to a well-prepared dental workforce capable of meeting the rapidly evolving needs of our society.

Analysing M. Avium-Macrophage Interactions And Establishing A Long-Term Infection In A Novel And Realistic Model Of Lung Alveolar Macrophages, Max Planck Institute Cells, Sanduni Avishka Thantri Hewage Peiris

Other Faculty of Health Theses

Mycobacterium avium Complex (MAC) are species of the non-tuberculous branch of the Mycobacteria family that is responsible for the development of pulmonary lung disease in immunocompromised individuals. One of the first lines of defence from the host involve a specialised group of tissue macrophages that reside in the lung alveolar space called alveolar macrophages (AM). They have specialised functions that are suitable for recognition of foreign invaders and the ability to tackle these threats though means of a robust immune response. Alternatively, they also feature as key components in a fairly destructive uncontrolled inflammatory response which is the root cause …

Silence In Market Reaction To Annual Reports, Magdalena Kochanowicz

Other Faculty of Arts, Humanities and Business Theses

Research problem - The literature suggests that the market either does not react or reacts with a delay to the content of annual reports, concerning notion given their importance for investment decisions due to the value relevance of the information they convey. According to the Efficient Market Hypothesis, the market should exhibit a prompt reaction to their release. Rationale - This study aims to uncover the underlying reasons for investors' lack of response to annual report filings. It predicts that the reaction depends, among other factors, on the release of preliminary disclosures of financial results, the method of distribution of …

College of Communication Faculty Research and Publications

This study explores the intermedia agenda-setting of the U.S. gun control movement in 2018, with a specific focus on the role of activism/advocacy media and ephemeral websites in shaping the movement discourse in news outlets. Structural topic modeling and cross-lagged correlation analyses of the Facebook URLs Share dataset show that activism/advocacy media played an important role in proposing unique agendas and aligning them with other news outlets. Meanwhile, ephemeral websites were prone to containing conspiratorial information, which could have been purposive to influence the movement. The study provides empirical insights into how various media actors interact to shape social movement …

Knowledge Construction And Multiple Realities: Global Health Collaborations, Development Practices, And Face Masks In The Context Of Covid-19, Linan Zhang

School of Art, Design and Architecture Theses

This thesis is inspired by a global health collaborative programme named GRASPIT and by my own desire to do something good which can benefit the people in need as well as reduce suffering. The GRASPIT collaboration intended to improve post-operative outcomes, but the programme failed to deliver the expected result. Preliminary analysis by the GRASPIT team identified issues with knowledge sharing as one of the contributory causes of its failure. This prompted the reflection in this thesis upon apparent asymmetries when knowledge is shared. Quite soon after the research began, the global pandemic COVID-19 revealed the issue of having inconsistent …

Film Here Now: Daily Filmmaking And The Path To Well-Being, Raul Alvarez

School of Art, Design and Architecture Theses

Film Here Now investigates the relationship between filmmaking and well-being with two specific aims: to illuminate how and why the process of making films inflicts stress on the filmmaker, and to determine what can be done within this process to prioritize the filmmaker’s well-being. My empirical framework of inquiry combines a particular filmmaking practice with a reflexive analysis of my experiences and observations. The practice component of my research consists of the daily production of films that adopt the aesthetic of Actualities, the minute long, single non-moving shot films by the Lumière Brothers, Thomas Edison and W. K. L. Dickson …
