Faculty Research, Scholarly, and Creative Activity

Induction of a CO2 partial pressure (pCO2) deficit in the surface-ocean through ocean alkalinity enhancement (OAE) or direct ocean removal (DOR) methods has been recognized as a promising approach to meet the projected need for negative CO2 emissions. The difficulty of directly measuring the counterfactual CO2 flux due to rapid spreading of the DIC-deficient plume has put ocean circulation models in the center of the Measurement, Reporting and Verification (MRV) challenge. Confidence in the results of such models is essential for the emerging industry to access carbon credit markets and grow at the required pace, to reach substantial negative emissions …

Well-Being And The New Economics Of Labor Migration Theory: A Study Of Elderly Left-Behind Parents In Guatemala, Dawn Marie Lawson

Doctoral Dissertations and Projects

This quantitative study tested whether multidimensional self-assessed well-being constitutes a suitable dimension for extending the New Economics of Labor Migration (NELM) framework. Specifically, the study examined the association between perceived migration-related material outcomes, namely consumption of market goods, savings, property holding, and business ownership or expansion, and self-assessed well-being among left-behind elderly parents in Guatemala. Well-being was operationalized using the Well-Being of Older People instrument (WOOP), a measure that the study established as culturally relevant to the sample. Given the ordinal levels of measurement used to capture the variables, the study used nonparametric statistical methods, viz., Kendall’s tau-b, Spearman’s rho, …

Desegregation Of The Ranks: How The United States Military Was The First Professional Organization To Integrate All Ethnic Groups, Matthew Lee Spiller

Masters Theses

A nation’s military has often been at the forefront of social progression. The Spartans, a military society, granted women a voice in government and a degree of autonomy over their own lives, while the Athenians—the founders of democracy—considered women second-class citizens with no control over their own affairs. The United States military is no different, striving to ensure fair and equal treatment of all ethnicities within the armed forces. In 1948, President Harry S. Truman issued Executive Order 9981, which desegregated the United States military—six years before the desegregation of public schools in Brown v. Board of Education (1954). This …

The Effects Of Anti-Gdnf On The Sensory And Autonomic Nervous System In The Heart, Tryphosa Konadu

Honors Theses

Heart disease is the number one leading cause of death; about 1 in every five deaths is due to heart disease. “Heart disease” is a catch-all phrase that encompasses a variety of conditions that affect the heart’s structure and function. Many of these symptoms can be attributed to dysfunction within the parasympathetic, sympathetic, and sensory nervous systems. Neurotrophic factors like GDNF (Glial cell line-derived neurotrophic factor), BDNF (Brain-derived neurotrophic factor), and NGF (Nerve growth factor) promotes neuronal survival, and regeneration of the nerve fibers of the heart, especially sensory and autonomic nerve fibers. Studies have suggested that increased expression of …

Drifting Neurons, Stable Geometry: Population Representations Of Instrumental Behavior In The Dorsomedial Striatum, Arati Sharma

Dartmouth College Ph.D Dissertations

The brain reliably supports learned behaviors over long periods of time despite continual biological changes that alter the activity of individual neurons, and the connections between them. For learned behaviors to persist, the information stored in neural populations must remain accessible even when the activity of individual neurons changes. Understanding how the brain achieves this is a fundamental challenge in neuroscience. The dorsomedial striatum (DMS) is critical for instrumental behavior, encoding information about actions, outcomes, and their relationships. Although extensive work has characterized the role of the DMS during learning and performance, less is known about how task-related information is …

More data are needed concerning these early changes in the coronary artery molecular landscape that signify the initiation of atherosclerosis and the subsequent tissue pheno-conversion to atherosclerotic plaque. This report summarizes results from a large biorepository of human coronary artery tissue, applying state-of-the-art omics technology, advanced data analytic methods, and an arterial organoid model system to predict molecular dynamics and identify potential regulatory mechanisms that could interrupt …

Unpredictability Is A Childhood Adversity That Contributes To Mental Health Problems, Laura M. Glynn, Sabrina R. Liu, Charles Golden, Michael Weiss, Candice Taylor Lucas, Louis Ehwerhemuepha, Hal S. Stern, Tallie Z. Baram

Psychology Faculty Articles and Research

Although adverse childhood experiences (ACEs) increase risk for mental illness at the population level, existing ACEs screens are less helpful in forecasting individual outcomes, suggesting they may not capture significant elements of childhood adversity. We have previously identified unpredictable parental and household experiences as an ACE that portends poorer cognitive and mental health. However, the contribution of unpredictability to established ACEs in real-world settings is unknown. Here, leveraging existing ACEs screening in California, we added the five-item Questionnaire on Unpredictability in Childhood (QUIC-5) in 19 pediatric clinics spanning broad sociodemographic constituencies and compared in ~30,000 children the link of each …
