Use Of Unoccupied Aerial Vehicle (Drones) Based Remote Sensing To Model Platform Topography And Identify Human-Made Earthen Barriers In Salt Marshes, Joshua J. Ward

Masters Theses

Elevation is a foundational driver of salt marsh morphology. Elevation governs inundation and hydrological patterns, vegetation distribution, and soil health. Anthropogenic impacts at grand scales (e.g., rising sea levels) and local scales (e.g., infrastructure) have altered the elevation of the salt marsh surface, changing the topography and morphology of these ecosystems. This study establishes and assesses means to document and analyze these impacts using Unoccupied Aerial Vehicle (UAV) based remote sensing to model platform topography. This thesis’s first and primary study presents and compares methods of producing high-resolution digital terrain models (DTMs) with UAV-based Digital Aerial Photogrammetry (DAP) and Light …

Multi-Method Approach To Assess The Impact Of Off-Fault Deformation During Fault Evolution, Christ Faviana Ramos Sanchez

Masters Theses

Scaled physical experiments using analog materials that simulate deformation processes in the Earth’s crust provide direct observations of deformation during strike-slip fault evolution. Carefully scaled experiments allow us to directly observe millions of years of deformation within hours and document the behavior of experimental faults. My thesis is composed of three distinct chapters that use scaled physical experiments to help us better understand partitioning of deformation on and off of strike-slip faults within the Earth’s crust. For my first project, I built a workflow that allows the measurement of off-fault deformation manifested as vertical motions along faults. When combined with …

Evaluation Of Antioxidant Strategies In Low-Moisture Foods, Vinatee Patil

Masters Theses

Lipid oxidation in foods is vastly studied and yet less is known about lipid oxidation mechanisms in low-moisture food systems. Low-moisture foods are comprised of almost all snacks. Most of these snacks are baked or deep-fried foods consisting of a major chunk of saturated fat in consumers’ diets. Therefore, the goal is to improve the nutritional profile of these products to ultimately deliver a healthy product to the consumer. Replacing saturated fats with healthy unsaturated fatty acids is a challenge the food industry faces daily due to oxidative stability.

This study aims to mimic and optimize the industrial cracker model …

Buffering Effects Of Negative Intergroup Contact Through Complex Social Identities, Liora Morhayim

Masters Theses

Although negative intergroup contact occurs less frequently than positive contact, negative contact can more strongly influence outgroup attitudes and behaviors due to the effect of category salience in the generalization process. The present study (N =306) tests whether being aware of an outgroup member’s complex social identity will serve as a buffer against the adverse impact of a negative intergroup contact experience on outgroup attitudes. In a 3X2 between-subjects design, social identity complexity (SIC) of an outgroup confederate (high versus low versus control) and the valence of contact (neutral versus negative) were manipulated. Participants interacted with an outgroup confederate …

Unraveling Intermolecular Vwfa1-Gp1bα And Vwf C4-Gp2b3a Interactions Using Atomic Force Microscopy, Sherly Makar

Masters Theses

Von Willebrand factor (VWF) is one of the largest and most complex glycoproteins. It is the main player in maintaining hemostasis at injury sites in the blood vessels as it bridges the interaction between blood platelets and the extracellular matrix (ECM). VWF acts as a mechanosensor in high-shear surroundings, leading to a conformational change in its domains. VWF is a mosaic protein with many different domains that are receptors to the proper ligands on the blood platelets. The A1 domain is the initial point of contact between the VWF and the blood platelets as it binds to the glycoprotein 1b- …

Investigating The Role Of Got2 In Murine Organogenesis And Placenta Development, Olivia Macrorie

Masters Theses

According to the Knockout Mouse Project (KOMP), loss of glutamatic oxaloacetic transaminase 2 (Got2) results in lethality between embryonic day (E) 9.5 and E12.5, which is a critical period for organ and placenta development. The first aim of this project is to characterize the KOMP-generated Got2 null allele. In situ hybridization reveals that while Got2 is ubiquitous throughout much of the embryo, it is highly expressed in the liver and throughout the developing labyrinth layer of the placenta by E9.5. While Got2^-/- embryos are lethal at E10.5, at E9.5 Got2-deficient embryos have pharyngeal arch defects, do not turn properly, …

Extracting Dnn Architectures Via Runtime Profiling On Mobile Gpus, Dong Hyub Kim

Masters Theses

Due to significant investment, research, and development efforts over the past decade, deep neural networks (DNNs) have achieved notable advancements in classification and regression domains. As a result, DNNs are considered valuable intellectual property for artificial intelligence providers. Prior work has demonstrated highly effective model extraction attacks which steal a DNN, dismantling the provider’s business model and paving the way for unethical or malicious activities, such as misuse of personal data, safety risks in critical systems, or spreading misinformation. This thesis explores the feasibility of model extraction attacks on mobile devices using aggregated runtime profiles as a side-channel to leak …

Structural Racism, Black Out-Group Preference, And Mental Health, Alexander J. Kellogg

Masters Theses

Structural racism has increasingly been implicated as a root cause of racial disparities in health and well-being. Specifically, areas where White Americans hold more negative attitudes toward Black Americans have been associated with both anti-Black discrimination and poorer Black physical and mental health. However, previous research has relied on cross-sectional designs and has neglected the potential effects of Black community-level attitudes on mental health. We hypothesized that higher aggregate pro-White bias among White Americans would be associated with higher implicit out-group preference among Black residents living in the same communities, above and beyond the effects of traditional measures of structural …

An Antiviral Response Unleashed: Deciphering The Relationship Between Shiftless And Rna Granules During Kshv Infection, David C. Hatfield

Masters Theses

Herpesviruses persist as a parasitic actor among many species. These viral agents can rapidly seize control over host cells by influencing global gene expression. Through a process known as host shutoff, herpesviruses cause a widespread degradation event of host transcripts within the cytoplasm. Specifically, Kaposi Sarcoma associated herpesvirus (KSHV) encodes for an endoribonuclease, termed SOX, that orchestrates this manipulation of gene expression. We and others have discovered certain transcripts that escape this fate; we suggest that this is an active escape, where transcripts have 3’ UTR elements that disallow SOX cleavage. One of the escapees that has been found is …

'Our Sacred Rights': The Southern Baptist Convention And The Rhetoric Of Oppression, 1845 And Present Day, Katlyn Durand

Masters Theses

My master’s thesis focuses on the endurance of white supremacy and patriarchy in the Southern Baptist Convention (SBC), founded in 1845 and currently the largest Protestant denomination in the United States. I look at two moments in the SBC’s history and place these moments within their broader contexts to elucidate the political and cultural characteristics that shaped these moments: its founding in 1845 upon proslavery partisanship, as well as its current sexual abuse scandal. I argue that the Nullification Crisis of 1828-1834 and the cult of domesticity greatly influenced SBC policy and culture at its origins. Additionally, I examine the …

Effects Of Habitat, Density, And Climate On Moose And Winter Tick Ecology In The Northeastern U.S., Juliana Berube

Masters Theses

Over the past several decades, moose (Alces alces) populations in New England have been in decline due to winter tick (Dermacentor albipictus) parasitism. Winter ticks have been known to infest moose, with over 90,000 ticks being recorded on a single moose. These severe infestations, known as epizootics, are associated with high annual calf mortality rates (> 50%) and reductions in annual productivity (adult calving and twinning rates < 60% and 5%, respectively). Given this, it is increasingly important to effectively monitor moose and winter ticks to address consistent population decline of moose due to winter tick epizootics. The objectives of this work were to measure off-host winter tick abundance and associated environmental variables and compare off-host tick abundance in relation to moose abundance.

To assess moose and winter tick abundance, I used a combination of camera traps and winter tick sampling. I set an array of 60 cameras across central-western Massachusetts, which …

The Impact Of A Non-Ionic Adjuvant To The Persistence Of Pesticides On Produce Surfaces, Daniel Barnes

Masters Theses

Adjuvants can enhance the performance of the pesticide active ingredients in many ways including decreasing surface tension and reducing evaporation. Understanding how adjuvants effect pesticide behavior (e.g., surface persistence) is crucial for developing effective pesticide formulations, as well as facilitating the development of effective approaches to reduce pesticide residues from the surface of fresh produce post-harvest. The objective of this study is to investigate the effect of a non-ionic surfactant, Surf-Ac 910, on the persistence of two model pesticides, thiabendazole and phosmet on apple surfaces. The result shows that the addition of Surf-Ac 910 increased both the maximum wetted area …

Comparing Likelihood Of Tree Failure Assessments Using Different Assessment Techniques, Ari Okun

Masters Theses

Tree risk assessment is an important arboricultural practice used to determine a tree’s risk of failing and causing damage to property or injury to people. Risk assessment includes three assessments: the likelihood of failure, the likelihood of striking a target, and the severity of consequences. To assess the likelihood of tree failure, arborists consider factors that affect the loads a tree experiences (for example, whether it is sheltered or exposed to strong winds, whether the crown is porous or dense, and how tall and wide is the crown) and factors that affect its load-bearing capacity (for example, what is the …

Masters Theses

The reproductive biology of anadromous rainbow smelt, Osmerus mordax (Mitchill), in the Parker River-Plum Island Sound estuary was investigated during the fall 1974 and spring 1975. Only one set of maturing eggs was observed within the ovaries of fish examined; all ovarian locations matured at a similar rate. Larger fish produced larger ovaries and eggs but fewer eggs per gram of ovarian weight. Mean maturity indices for females and males during November through March increased 576.7% and 72.1%, respectively. Total fecundity ranged from 7,038 eggs for an age I, 127 mm female to 44,241 eggs for an age II, 204 …

Reproductive Biology Of Anadromous Rainbow Smelt, Osmerus Mordax, In The Ipswich Bay Area, Massachusetts, Frederick C. Sutter Iii

Masters Theses

The reproductive biology of anadromous rainbow smelt, Osmerus mordax, was investigated in the Parker River and Essex Bay systems from 1977 through 1979. Variations in growth and seasonal energy content of body tissue of young-of-the-year (YOY) anadromous smelt were examined to investigate their relationships to spawning of precocious (age I) fish. By late fall of their first year, YOY that will spawn precociously in the spring have developing gonads, are longer in total length and have a higher energy content (kcals/g) of body tissue than non-precocious fish. The number of fish spawning at age I increased during the spawning …

Teacher acceptability and preferences for praise and reprimand were collected through the Teacher Praise and Reprimand Preference Survey (TPRPS) which is a survey adapted from the previously existing Adolescent Preference for Praise Survey (APPS). A total of 140 teachers from rural, suburban, and urban school districts completed the TPRPS survey. Results of the study showed that as grade level increased, teachers reported to praise students …

Burnout In Resident Assistants Of Color, Lily Weaver

Masters Theses

Burnout among Resident Assistants is very common due to the physically and emotionally demanding nature of the position (Stoner, 2017). For RAs of color, experiencing racism on campus and the barriers to higher education BIPOC individuals face can push them towards burnout more quickly (Jackson, 2012; Hotchkins & Dancy, 2017; Harper et al., 2011). While a multitude of research has been done on RA burnout, there is a significant gap in the literature regarding the BIPOC RA experience of burnout. This qualitative study used semi-structured interviews to examine how burnout in BIPOC RAs could be connected to their race. The …
