Filamentous Green Algae (Cladophora Glomerata) In Near Shore Lake Ontario: An Investigation Of Tissue And Water Nutrient Dynamics Through A Period Of Growth And Decomposition., James L. Wagner Jr

Biology Theses

Cladophora glomerata, a filamentous green alga abundant in the Laurentian Great Lakes, has long been considered a nuisance throughout the region. Previous phosphorus (P) abatement practices and legislation successfully reduced the abundance of the algae, but with the introduction of dreissenid mussels, a resurgence has been observed. Though there is substantial literature and modeling of the growth cycle of Cladophora, relatively little research has been dedicated to the decomposition stage of the algae, a period which may contribute to a substantial influx of nutrients to near-shore environmental regions. By first examining a period of in-situ growth within Lake …

Converting Hydrazone-Based Photoswitches Into Functional Materials, Sirun Yang

Dartmouth College Ph.D Dissertations

The development of new classes of molecular switches with enhanced performance and brand-new functionalities enables practitioners to push the frontiers of adaptive materials. In the realm of photoswitches, the bistability of hydrazones (i.e., molecules that incorporate the C=N-NH functional group) allows for the kinetic trapping of polymer and supramolecular assemblies resulting in multistate actuation and emergent phenomena that are not tractable with other photoswitches. This property has transformed hydrazone photoswitches into powerful tools that can be used in understanding fundamental molecular interactions and how to apply them in modulating the physicochemical properties of materials.

Household Salt Production By The Late Classic Maya: Underwater Excavations At Ta'ab Nuk Na, Heather Mckillop, E. Cory Sills

Geography Faculty Publications and Presentations

Salt is an essential commodity; archaeological remains around the world attest to the importance of its production, exchange and consumption. Often located in coastal locations, many production sites were submerged by rising seas, including the Paynes Creek Salt Works on the southern Belize coast. Survey and excavation of these sites has identified ‘kitchens’ for brine boiling, as well as Terminal Classic residential structures at Ek Way Nal. The authors report the discovery of an earlier residential building alongside salt kitchens at the nearby site of Ta'ab Nuk Na. This finding indicates that surplus household production began during the Late Classic, …

Large herbivore migrations are imperiled globally; however the factors limiting a population across its migratory range are typically poorly understood. Zambia's Greater Liuwa Ecosystem (GLE) contains one of the largest remaining blue wildebeest (Connochaetes taurinus taurinus) migrations, yet the population structure, vital rates, and limiting factors are virtually unknown. We conducted a long-term demographic study of GLE wildebeest from 2012 to 2019 of 107 collared adult females and their calves, 7352 herd observations, 12 aerial population surveys, and concurrent carnivore studies. We applied methods of vital rate estimation and survival analysis within a Bayesian estimation framework. From herd …

Estimating Natural Background Water Quality In California Rivers, Emma A. Debasitis

AES Theses

Water chemistry affects organisms at all levels of the food web in aquatic habitats. Water quality alteration from natural conditions can seriously degrade habitat quality, human health, and the survival rate of native species. Estimating background (i.e., historic or baseline) water quality of impaired streams can be difficult due to the effects of anthropogenic involvement in aquatic systems over decades to centuries. The ability to model natural background water quality levels would aid in overall stream management. The natural background predictions provided by a model would allow for increased understanding of stream condition and would allow us to determine the …

Recreational Fishing For Western Rock Lobster: Estimates Of Participation, Effort And Catch In 2021/22, Claire B. Smallwood, Karina L. Ryan, Alissa C. Tate, Lucy J. Rudd

Fisheries Research Reports

The Western Rock Lobster (WRL) (Panulirus cygnus) is the most commonly caught Rock Lobster (RL) species in Western Australia. Catches from the commercial and recreational sectors are required to determine and monitor Total Allowable Commercial Catch (TACC), Total Allowable Recreational Catch (TARC) and proportion of Allowable Harvest Level (AHL) achieved. The TARC is set at 5% of the AHL and evaluated in the harvest strategy based on a 5-year average. Since 2018/19, data for the recreational sector have been collected using phone- recall surveys to provide estimates of participation, fishing effort and retained catch (by numbers) from recreational fishers who …

Landscape Change, Scale, And Human Response To Change In The Great Plains, Kate Bird

School of Natural Resources: Dissertations, Theses, and Student Research

Great Plains landscapes are undergoing changes at multiple spatial and temporal scales due to processes ranging from woody encroachment to climate change. These changes may fundamentally alter the agroecosystems of the Great Plains such that the provisioning of ecosystem services including biodiversity and livestock production is affected. Improving our understanding of the effects of landscape change at multiple scales and how humans perceive and respond to these changes is important for facilitating research and management that enhances the resilience of these agroecosystems. As such, I first applied discontinuity theory and graph theory to evaluate the functional connectivity of the Central …

Stress Arising From The Covid-19 Pandemic: Impacts On Coparenting Quality And Child Internalizing And Externalizing Problems, Michelle R. Ebrahim

Honors Program: Senior Projects (Public)

Since emerging in late 2019, the highly contagious coronavirus disease (COVID-19) has caused worldwide disruptions, with major shutdowns in school, work, and other aspects of life. These stressors uniquely impacted families with young children. The present study investigated the impact of the pandemic on family functioning and risk for child internalizing and externalizing problems during the first year after the pandemic. The study included three waves of data collection from a larger longitudinal study aimed at understanding how couples navigate the prenatal-postpartum transition and the impacts of the family on early child development. We found that family pandemic-related stress was …

Title Ix's Trans Panic, Deborah L. Brake

William & Mary Journal of Race, Gender, and Social Justice

Sport has long been a site of struggle over competing conceptions of social justice, with no cultural flashpoint more contested than gender. A key site of contention has been the meaning and application of Title IX. With June of 2022 marking the law’s fiftieth anniversary, Title IX has been lauded as the law that launched girls’ and women’s sports from the shadows to their present, more celebrated posture. As these anniversary tributes often emphasize, female athletic participation has soared to new heights in all levels of sports. But Title IX also houses tensions and dilemmas for gender justice that were …

What's Wrong With The Ncaa's New Transgender Athlete Policy?, Erin Buzuvis

William & Mary Journal of Race, Gender, and Social Justice

In 2022, the NCAA changed its long-standing policy permitting transgender athletes to participate in teams that correspond to their affirmed gender. For twelve years, the NCAA permitted transgender women to participate in women’s sports events under NCAA control, so long as they first underwent a year of androgen suppression. Starting in 2020, however, a political movement to ban transgender women and girls from competing in women’s sport, galvanized by backlash against a single collegiate swimmer, has challenged NCAA’s inclusive approach. Rather than demonstrate leadership and support for rights of transgender women to compete, the NCAA revised its policy to one …

Evidence For Particle Dilution And Dispersion As The Strongest Effects On Reach-Scale Salmonid Edna Sampling Outcomes In Mediterranean-Climate Rivers And Streams, Shawn A. Melendy

AES Theses

Environmental DNA (eDNA) sampling from rivers has emerged as a promising new method for monitoring freshwater organisms of management concern. However, to more confidently interpret eDNA sampling results – and thereby improve eDNA as a tool for management decision making – the influence of local environmental factors on eDNA fate (transport & decay dynamics) must be better understood. At nine river sites across the central California coast, we added a known quantity of novel eDNA (Brook Trout, Salvelinus fontinalis) and collected eDNA at sequential downstream distances for qPCR analysis. We then used random forest modeling to identify the most …

Pancreatic Lymphoepithelial Cyst With Concurrent Hiv Infection: A Case Report And Review Of The Literature, Oluwayomi Oyedeji, Shannon Rodgers, Allen Wrubel, Rupen Shah, Sanam Husain

Pathology and Laboratory Medicine Articles

Pancreatic lymphoepithelial cysts are rare, benign, non-neoplastic unilocular or multilocular cystic lesions. These circumscribed pancreatic lesions are filled with keratinous material grossly and exhibit distinct microscopic features. Pancreatic lymphoepithelial cysts are like the more common lymphoepithelial cysts of the parotid glands, which have been associated with the diffuse infiltrative lymphocytosis syndrome often seen in patients with HIV infection. However, pancreatic lymphoepithelial cysts are rare and their association with HIV infection has not been established. The presence of secondary changes in non-neoplastic cysts such as goblet cell metaplasia that was present in our case is an important feature to be included …

Birthing Alone, Elizabeth Kukura

Washington and Lee Law Review

Throughout the COVID-19 pandemic, hospitals implemented restrictive visitor policies that have prevented many pregnant people from giving birth with their chosen support people. For some, this meant foregoing labor and delivery support by a birth doula, someone who serves in a nonclinical role and provides emotional, physical, and informational support to birthing people. Given that continuous labor support such as the care provided by doulas is associated with fewer cesareans and other interventions, less need for pain medication, and shorter labors, the promotion of doula care is a promising strategy to ease the maternal health crisis and, in particular, shrink …

Leave Them Kids Alone: State Constitutional Protections For Gender-Affirming Healthcare, Jessica Matsuda

Washington and Lee Law Review

State legislatures across the nation are continually targeting the rights of transgender individuals with a variety of laws affecting everything from bathrooms to medical care. One particularly invasive type of legislation, the gender-affirming healthcare ban, seeks to prohibit all forms of healthcare that align a person’s physical traits with their gender identity for individuals under eighteen. Bans like this severely impede the treatment necessary for transgender youth suffering from gender dysphoria, which carries serious physical consequences and sometimes fatal psychological repercussions. As legislative sessions pass, more and more states are introducing and actually enacting these bans

Striking down these bans …

A Proposed Tourism Cap On The Galapagos Islands: Beyond The Wildlife, Hannah M. Robertson

William & Mary Environmental Law and Policy Review

Scientists have pleaded to both Galápagos and Ecuadorian officials to impose a tourism cap on land-based tourism to protect the biodiversity of the Islands. However, these proposals have offered little to no means of addressing the economic concerns or offsetting the impact a tourism cap would have on key revenue-producing industries and locals. Because of this, proposals for land-based tourism caps have gained little traction within Ecuador and the Galápagos.

This Note should serve as a guide for assessing what tourist restrictions are possible and how those restrictions would be implemented. Part I begins with an overview of the environmental …

Apologetics And Disability: Reframing Our Response To The Question Of Suffering, Rochelle Scheurermann

Great Commission Research Journal

A prominent question that is asked when people consider God is how to account for suffering if God is good and all-powerful. For Christians, answering this question is a major part of apologetic and evangelistic training. But what if the way we have traditionally approached this question is not good news for everyone? This paper examines the suffering question in light of disabilities and suggests a new way to engage in apologetics that is centered in creation (not fall) and celebrates the gifts and opportunities that come through a diversity of ability.

Passive, Self-Healable, Dielectric Elastomers For Structural Health Monitoring, Nicholas Smith

Doctoral Dissertations and Master's Theses

NASA maintains the ability to track a large majority of objects in Earth’s orbit, however lack the ability to track objects smaller than five centimeters in diameter. These untrackable objects represent a significant danger to inflatable structures. This work seeks to synthesize and fabricate a self-healable, passive, dielectric elastomer impact sensor for structural health monitoring on inflatable space structures subject to impact by micrometeoroids and orbital debris. In a setting in which impact repairs can be extremely costly, the implementation of such a technology would not only alert personnel of such an event but would also serve to decrease the …

The geographical variability, frequency content, and vertical structure of near-surface oceanic kinetic energy (KE) are important for air-sea interaction, marine ecosystems, operational oceanography, pollutant tracking, and interpreting remotely sensed velocity measurements. Here, KE in high-resolution global simulations (HYbrid Coordinate Ocean Model; HYCOM, and Massachusetts Institute of Technology general circulation model; MITgcm), at the sea surface (0 m) and at 15 m, are compared with KE from undrogued and drogued surface drifters, respectively. Global maps and zonal averages are computed for low-frequency (

Berbamine Enhances The Efficacy Of Doxorubicin Treatment For Breast Cancer In Vitro And In Vivo, Kristina G. Borglum

Senior Theses

Doxorubicin (Dox) is a commonly used chemotherapy drug for treating breast cancer. While it is very effective, the main limitation of Dox treatment is subsequent cytotoxicity. Berbamine dihydrochloride (BBM) is a natural benzylisoquinoline alkaloid that is extracted from the plant, Berbaris amurensis. It has been widely used in traditional medicine to treat individuals with inflammatory diseases for many centuries. It has already been shown that combining BBM with Dox synergistically enhances the efficacy of Dox treatment on breast cancer in vitro. To eventually translate these findings into a clinical setting, this study aims to explore this therapeutic potential in vivo …
