Exploring Chronic Stress, Avoidance Coping, And Diurnal Cortisol In Head And Neck Cancer Patients: A Pilot Study Of Best Practices In Diurnal Cortisol Sampling., Brooks R. Harbison

Electronic Theses and Dissertations

Cancer patients are vulnerable to the deleterious effects of chronic stress, especially those prone to avoidance coping. Research in the general population has linked these effects to aberrant diurnal cortisol. However, the current literature on cancer patients has shown inconsistent results in associations between chronic stress, avoidance coping, and diurnal cortisol, possibly due to inconsistent cortisol sampling practices. This pilot study of head and neck cancer patients aimed to address this gap in the literature by implementing best cortisol sampling practices to investigate the links among chronic stress, avoidance coping, and diurnal cortisol slope, average bedtime cortisol, and average wake …

Examining The Role Of Presence Of Meaning In Life On Wellbeing In Emerging Adulthood., Hannah K. Heitz

Electronic Theses and Dissertations

Emerging adults face numerous challenges and stressors, such as financial stress, which often accompanies the experience of educational and occupational transitions. As such, it is important to identify personal resources, or protective factors, to help emerging adults buffer the experience of financial stress. Presence of meaning in life has been identified as a resource that can buffer the negative effects of stressors on wellbeing among adults and adolescents, yet there is little empirical evidence for its moderating effect among emerging adults. There is some evidence in the literature that suggests that emerging adults experience presence of meaning in life differently …

Scholars and commentators generally discuss the press function through …

Bridging Silos: Environmental And Reproductive Justice In The Climate Crisis, Sara A. Colangelo

Georgetown Law Faculty Publications and Other Works

The climate crisis is a perilous yet underexamined example of the intersection of environmental injustice and reproductive injustice. The physical manifestations of the climate crisis affect key elements of reproductive justice: women’s rights to have children, to not have children, and to parent children in healthy, sustainable communities. Reams of studies document climate disaster-driven gender violence, loss of access to healthcare and reproductive services, as well as direct and deadly health effects of climate change on maternal health, fetal development, infants, and children. Despite these profound impacts, the environmental and reproductive justice movements remain largely siloed, particularly in the legal …

How Is Access To Legal Resources And Advocacy Foundational To Health Justice?, Yael Zakai Cannon

Georgetown Law Faculty Publications and Other Works

Health justice as a movement incorporates research about how to more effectively leverage law, policy, and institutions to dismantle inequitable power distributions and accompanying patterns of marginalization that are root causes of health inequity. Legal advocacy is key to health justice because it addresses patients’ health-harming legal needs in housing, public benefits, employment, education, immigration, domestic violence, and other areas of law. In medical-legal partnerships, lawyers and clinicians are uniquely positioned to jointly identify and remove legal barriers to patients’ health, advocate for structural reform, and build community power.

Enhanced Rate Capability And Capacity Of Lib Full Cells Achieved Through Aerosol Jet Printing, Rodrigo Rodriguez, L. Jay Deiner, Bang-Hung S. Tsao, Joseph P. Fellner

Publications and Research

Thick lithium-iron phosphate (LFP) cathodes (31 mg cm−2) with rationally engineered pore structure and tortuosity were manufactured with an aerosol jet (AJ) printer. Cathode pore structuring was tuned by controlling the rate at which the printed ink dried. Slow-drying prints yielded smoother cathodes while fast-drying prints resulted in mesoscale structuring with substantial surface roughness. X-ray tomography further revealed that the rapid drying of AJ printed LFP cathodes produced low-tortuosity pore channels which were preserved after calendering. Full cells comprised of AJ print optimized LFP cathodes, with 30 mg cm−2 active material loadings, and capacity-matched, AJ printed lithium titanate anodes were …

The Q Is Chaos: Freedom 4 Artists Is Ostranenie, Cristian J. Alba-Dominguez

Theses, Dissertations and Culminating Projects

In this thesis, I suggest that ostranenie is the artistic equivalent of chaos and it can be used by artists to grab and maintain the perception of an audience through the disruption of norms or pre-established conditions. Ostranenie, the device of art introduced by Russian Formalist Victor Shklovsky in his essay, “Art as Device,” is a device that gives absolute freedom to the creative person who isn’t afraid to use it to create original and engaging work. In the novel, 1Q84, Haruki Murakami utilizes ostranenie to tell a simple love story in a manner that prolongs the reunion of his …

Value Of Macroalgae As Habitat In A Eutrophic Coastal Bay, Dominika Polchowska

Theses, Dissertations and Culminating Projects

Eutrophication is a phenomenon caused by changes in nutrient loading that results in harmful algal blooms, an overgrowth of macroalgae, altered aquatic benthic invertebrate communities, and loss of ecosystem functions. Barnegat Bay, NJ is a highly eutrophic system that has experienced a substantial loss of seagrass beds with subsequent expansion of drift macroalgae. Although considered poor quality, these algal beds represent valuable habitat for many benthic invertebrates. This research assesses the value of macroalgae as a habitat for macrofauna in regions where macroalgae are the dominant “vegetation.” Benthic drift algal samples were collected during June and August 2023 to reflect …

Transferred Benefits In Inter-Community Beach Nourishment: A Field Study On Efficiency, Owen Thomas

Theses, Dissertations and Culminating Projects

To combat the effects of relative sea level rise and the natural erosional processes affecting the sandy, diffusive beaches of New Jersey, most communities utilize beach nourishment to stabilize their beaches. Beach nourishment, the practice of artificially widening the beach berm with sand from other areas, not only stabilizes beaches but also protects oceanfront homes from storm surges, while adding recreational space and tourism value. These benefits are reflected in increased property values, most notably in oceanfront properties. The diffusive nature of these beaches, however, means that individual nourishment events are inherently shared with neighboring communities as sand is readily …
