Mechanistic And Toxicokinetic Analysis Of Perfluoroalkyl Substances: Proteomics Approach And The Role Of Fatty Acid Binding (Fabp), Seyed Mohamad Sadegh Modaresi

Open Access Dissertations

Per- and polyfluoroalkyl substances (PFAS) are persistent chemicals used in many industries, known for their resilience and resistance to degradation. The extended half-lives of PFAS in the human body result in bioaccumulation, with serum half-lives for perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), and perfluorohexane sulfonic acid (PFHxS) estimated at 3.4, 4.6, and 7.1 years, respectively. PFAS primarily accumulate in the liver, hypothesized due to their resemblance to fatty acids and their binding with liver fatty acid-binding proteins (LFABP), affecting lipid metabolism and leading to liver toxicity. Although extensive research has been performed on long-chain PFAS over the past decade, …

Strategies To Stress Less: A Meta-Analytic Review Of The Effects Of Mindfulness-Based Stress Reduction (Mbsr) On Self-Reported Stress, Gregory J. Champion

Open Access Dissertations

Introduction: Stress negatively impacts health, well-being, and productivity. Mindfulness-based stress reduction (MBSR) interventions are a promising strategy to reduce stress, but they are not covered by most health insurance policies in the United States (US). A recent Delphi process gathered feedback from key stakeholders, such as clinicians, MBSR instructors and students, policymakers, healthcare administrators, and health insurance company leaders. The results indicated synthesizing the existing evidence of the impact of MBSR interventions on stress was the 2nd highest priority out of 43 options evaluated. Past research has indicated MBSR interventions may be as effective as active controls at reducing …

Treading Carefully In The Deep Ocean: Insights Into The Effects Of Artificial Light And Sound From Robotic Platforms On Pelagic Animal Surveys Using Active Acoustics And Low-Light Imaging Techniques, Rendhy Moreno Sapiie

Open Access Dissertations

Science and technology are coupled disciplines. Breakthroughs in ocean science are often pertinent to the ability to observe physical, chemical, and biological processes at the right temporal and spatial scales, which typically involves the use of robots. Large, powerful, and extremely capable, the scientific work-class remotely operated vehicle (ROV) is the golden standard when observing fine temporal scale intricate processes in the full ocean stratum and has unraveled important discoveries in deep-sea biology and ecology. Sound, light, and hydrodynamic forces produced from these vehicles are sources of disturbances that may impact quantitative observations in the twilight zone, an environment absent …

From Page To Stage: Enlightenment Common Sense & The Semiotics Of The Body, 1660–1820, Nilton X. Gomes

Open Access Dissertations

How did eighteenth-century audience members or novel readers come to see beyond the facades of literary characters and narrators? By looking into moments of bodily concealment in the eighteenth-century novel and theater, this dissertation examines how authors and playwrights in this period wrote with subtly and force to make the body as and in many instances more legible to their readers as the words on the page or the dialogues on the stage in attempts to suture the gap that lies between what a writer intends and what a reader grasps in a literary work. It also stresses the body’s …

The Distribution And Habitat Use Of Semi-Aquatic Mammals In A Changing New England Landscape, Josh Crockett

Open Access Dissertations

Semi-aquatic mammals (i.e., animals that depend on both terrestrial and aquatic environments for their daily needs) are an ecologically and economically important group, but they are often difficult to monitor because of their restricted habitat which makes them unlikely to appear in monitoring schemes designed for all mammals (e.g., camera trapping). Rhode Island is home to several semi-aquatic mammal species, including North American beavers (Castor canadensis), North American river otters (Lontra candensis), and muskrats (Ondatra zibethicus). Historically, these species were all exploited for their furs, which led to drastic declines in otter and (especially) …

This study employed survey research and focus group discussions with HBCU students in two courses. The …

Hantu Laut: The Ghosts Of Colonialism In Indonesia’S Marine Conservation, Nara Wisesa

Graduate Student Scholarship

In this paper, I investigate the enduring influence of Dutch colonial legacies on contemporary marine conservation governance in the Indonesian archipelago. Using Banu Subramaniam’s concept of interdisciplinary haunting and Bruno Latour’s Black Box metaphor, I critically examine how historical power structures established over three centuries of colonial rule shape present-day environmental policies. The analysis begins with my critique of the International Union for Conservation of Nature’s (IUCN) definition of conservation, highlighting inherent ambiguities regarding equity that may have enabled global power imbalances and the uneven distribution of costs and benefits. I continued by tracing the evolution of marine resource governance …

Polar oceans and sea ice cover 15% of the Earth’s ocean surface, and the environment is changing rapidly at both poles. Improving knowledge on the interactions between the atmospheric and oceanic realms in the polar regions, a Surface Ocean-Lower Atmosphere Study (SOLAS) project key focus, is essential to understanding the Earth system in the context of climate change. However, our ability to monitor the pace and magnitude of changes in the polar regions and evaluate their impacts for the rest of the globe is limited by both remoteness and sea-ice coverage. Sea ice not only supports biological activity and mediates …

Multi-Year Time Series Reveals Temporally Synchronous Diatom Communities With Annual Frequency Of Recurrence In A Temperate Estuary, Diana N. Fontaine, Tatiana A. Rynearson

Graduate School of Oceanography Faculty Publications

Diatoms are among the most abundant phytoplankton that inhabit coastal ecosystems, forming large blooms that fuel coastal food webs. Although diatoms are often large and morphologically distinct, many are small or morphologically cryptic making it difficult to understand the temporal dynamics of whole diatom communities and the environmental factors that drive them. Here, we investigated diatom diversity and its environmental correlates using 6 yr of monthly surface water samples from the Narragansett Bay Plankton Time Series to investigate the seasonal and annual variability of diatom species occurrence. High-throughput amplicon sequencing of filtered biomass yielded 658 diatom amplicon sequence variants (ASVs), …

Social Media Literacy: Sociocultural Instruction And Community College Students, Angela Kohnen, Christine Wusylko, Max Sommer

Journal of Media Literacy Education

Although literacy researchers have paid increasing attention to online information literacy, curricula are usually centered around webpages rather than social media, which is the more popular media platform for young adults. We developed and introduced a social media literacy curriculum to a summer bridge program for marginalized community college students. Our instruction was designed to center and build on students’ lived experiences, and we found that students purposes for using social media and their knowledge of credible sources was not aligned with traditional approaches to information literacy. Students perceived social media as a tool for fun and connectivity and their …

Niebergall, Shawnee Traylor, Yibin Huang, Melanie Feen, Meredith G. Meyer, Heather M. Mcnair, David Nicholson, Andrea J. Fassbender, Melissa M. Omand, Adrian Marchetti, Susanne Menden-Deuer, Weiyi Tang, Weida Gong, Philippe Tortell, Roberta Hamme, Nicolas Cassar

Graduate School of Oceanography Faculty Publications

New production (NP) and net community production (NCP) measurements are often used as estimates of carbon export potential from the mixed layer of the ocean, an important process in the regulation of global climate. Diverse methods can be used to measure NP and NCP, from research vessels, autonomous platforms, and remote sensing, each with its own set of benefits and uncertainties. The various methods are rarely applied simultaneously in a single location, limiting our ability for direct comparisons of the resulting measurements. In this study, we evaluated NP and NCP from thirteen independent datasets collected via in situ, in vitro, …

In Vitro Screening Of 12 Strains Of Birdsfoot Trefoil (Lotus Corniculatus) Against Haemonchus Contortus, Isabella Caldwell, Elizabeth Kass, Rebecca Brown, Katherine Harper Petersson

Senior Honors Projects

Gastrointestinal nematodes (GIN), primarily Haemonchus contortus, are one of the leading causes of death in sheep and goats. As resistance to commercial dewormers continues to rise, alternative strategies for GIN parasite control are needed. Preliminary studies have demonstrated that secondary plant compounds in birdsfoot trefoil (BFT, Lotus corniculatus) possess antiparasitic activity against GIN. In this study, the antiparasitic effect of twelve strains of BFT on the hatching of H. contortus eggs and motility of larvae was determined. BFT strains were harvested in June of 2020 and hay-dried. H. contortus eggs were recovered from mono-infected Dorset yearlings by running fresh …

This project will develop the script for a children’s television show in the expository format that …

Intercultural Film Literacy Education Against Cultural Mis-Representation: Finnish Visual Art Teachers’ Perspectives, Sergei Glotov

Journal of Media Literacy Education

Cultural misrepresentation simplifies cultures and their minorities, promotes racism, nationalism and eventually weakens democracies by spreading false information through audio-visual media. Intercultural film literacy education combines intercultural education and film literacy and uses a film as a starting point to discuss the cultural context, to analyse cultural representation and to evaluate how the culture is portrayed from a stylistic and formal point of view. The current study builds upon the previous research that linked intercultural education and film literacy to discuss how visual art teachers understand and practice intercultural film literacy education towards critical analyses of cultural representation in audio-visual …

Female Perpetrators Of Ritually Motivated Pedicide And Mutilation Of Children, Chima Agazue

Dignity: A Journal of Analysis of Exploitation and Violence

Ritually motivated pedicide is among contemporary Africa’s most severe crimes against children. Most of these crimes involve brutal acts of violence or mutilation of the victim. While men are most often the perpetrators of violent crimes, ritually motivated pedicide and mutilation equally attract women. The role of women in these crimes is not restricted to the less violent aspects of the crimes; instead, they also extend to the most brutal elements, often involving mutilation, decapitation or outright murder of the victim. This article explored the involvement of women in these crimes that target children for mutilation and pedicide. The article …

Price Analysis Of Aquafeed Containing Microalgae (Dunaliella Salina (Dunal) Teodoresco 1905 Meal For Color Enhancement In Shrimp, Wa Iba, Sumarno, Ruslaini, Agus Kurnia, Irdam Riani

Fisheries, Animal and Veterinary Sciences Faculty Publications

The price of aqua feed containing Dunaliella salina meal was calculated. Also, the formulated feed’s protein, lipid, and total carotenoid content were examined. The price of shrimp feed containing D. salina meal was higher than commercial feed with better protein and carotenoid content in the feed. This indicated that the inclusion of microalgae meal may increase coloration and growth in shrimp. We recommend using these formulated fish in shrimp aquaculture with necessary investment in microalgae meal and aqua feed production.
