Exploring The Role Of Recreation In Rural Nh Youth's Engagement With Master Narratives, Katelyn A. Moscouver

Master's Theses and Capstones

Rural youth often feel compelled to leave their home communities to seek new opportunities, especially at the secondary-postsecondary educational transition. These decisions are driven in part by perceived developmental imperatives to leave rural hometowns given messages that success is best achieved elsewhere. The present study used the framework of identity master narratives to explore recreation's role in facilitating youth postsecondary planning in rural northeastern state of New Hampshire. The study extends and deepens prior research seeking to understand some of the structural-psychological factors connecting recreation involvement in adolescence, postsecondary decision making, and broader demographic patterns among the 15-19 and 20-24 …

A Novel ‘Adjacent Mycorrhizal Symbiosis’ In Invasive Garlic Mustard, Joshua A. Trombley

Master's Theses and Capstones

Invasion of temperate forests by Alliaria petiolata (garlic mustard) may be affected by interactions with arbuscular mycorrhizal fungi (AMF). Although AMF are generally mutualists of land plants, they suppress the growth of close relatives of garlic mustard1–3. Garlic mustard produces indolic glucosinolates, a class of organic compounds known to suppress AMF4,5 and which may protect the plant from AMF antagonism. We would therefore expect a negative interaction between these organisms. Contrary to this expectation, we show that AMF inoculation promotes garlic mustard growth, and this effect is influenced by investments in plant defense. AMF inoculation and subsequent colonization increased plant …

Representation And The Achievement Gap: A Case For Prioritizing Cultural Sameness In The Classroom, Taryn J. Fears

M.S. in Leadership

Abstract

This study examined the impact of cultural representation on achievement for minority students academically and socially across diverse contexts. Recognizing the importance of cultural diversity in educational and youth mentoring settings, this research explores how the representation of various cultural identities, including race, ethnicity, gender, and socioeconomic status, influences student achievement outcomes. Coming from a background in community based nonprofit organizations, I have seen how black and brown students respond in classroom and out-of-school time settings when having come in contact with teachers and mentors of similar culture. Having a teacher and/or mentor of a similar culture creates pathways …

Characterizing Modality And Cognitive Effects In Implicit-Statistical Learning: Theoretical Implications For Language Learning In Adults, Katelyn Lerner

Master's Theses and Capstones

This study examined the presence of modality and cognitive effects within implicit statistical learning (ISL) to characterize how it operates within the context of language learning. The first research aim looked to investigate differences in ISL performance as it relates to modality, specifically auditory versus visual formats. Additionally, the relationship between cognitive measures and ISL task performance was investigated to characterize potential interactions between learning and cognition. In this study healthy adults between the ages of 18-35 were administered auditory and visual ISL experimental tasks. Participants were familiarized with a target grammar pattern in an exposure phase. After the exposure …

Using Tensile And Compressive Stress Superposition During Incremental Forming To Manipulate Martensitic Transformation In Ss304, E M. Mamros, F Maab, A E. Tekkaya, Brad L. Kinsey, J Ha

Faculty Publications

Single point incremental forming (SPIF) is a flexible manufacturing process that has applications in industries ranging from biomedical to automotive. In addition to rapid prototyping, which requires easy adaptations in geometry or material for design changes, control of the final part properties is desired. One strategy that can be implemented is stress superposition, which is the application of additional stresses during an existing manufacturing process. Tensile and compressive stresses applied during SPIF showed significant effects on the resulting microstructure in stainless steel 304 truncated square pyramids. Specifically, the amount of martensitic transformation was increased through stress superposed incremental forming. Finite …

Filling The Bathymetric Gaps: Toward Quantifying And Characterizing Uncertainty In Interpolated Bathymetry, Elias Opeyemi Adediran

Master's Theses and Capstones

The oceans remain one of Earth's most enigmatic frontiers, with approximately 75% of the world's oceans still unmapped to modern standards. To overcome this, interpolation serves as the primary method for creating seamless coverage from incomplete coverage hydrographic data sets and is essential for creating a seamless digital bathymetric model (DBM) compiled from sparse bathymetric datasets and set-line spacing surveys. While methods for quantifying the uncertainty in depth measurements are well-researched, interpolation introduces unqualified depth uncertainties. This study aims to estimate and characterize these uncertainties which are essential to nautical charting, and navigational safety, and important in many other fields.Organized …

Feminism In The Anti-Nuclear Movement: Three Women's Quest To Re-Make Society, Sarah Doenmez

Master's Theses and Capstones

In the 40 years between 1974 and 2014, the anti-nuclear movement arose in New England, shook the dominant political forces, changed the culture, and achieved significant victories. Although they are usually not recognized as the power behind anti-nuclear and environmental activism, in fact, I contend that a certain group of women motivated by a second wave ecofeminist vision of peace were and have remained the core of this work in New England. Their fight against patriarchal systems shaping their individual lives extended to a larger commitment to build communities and imbue institutions with a new value system that would nurture …

Fate Of Per- And Polyfluoroalkyl Substances In A Wastewater Treatment Facility Using A Novel Membrane Bioreactor, Lindsay Ann Guertin

Master's Theses and Capstones

Per- and polyfluoroalkyl substances (PFAS) are a broad class of chemicals known for their environmental persistence and unique thermal and chemical stability which has led them to be used in a variety of products including paper, carpets, clothes, cosmetics, food packaging, kitchen ware, chrome plating, and aqueous film forming foams (AFFFs). Their resistance to biochemical degradation has led regulators to be interested in reducing PFAS loads to the environment and sources that humans are exposed to (e.g. drinking water). Recent studies have shown that concentrations of some terminal PFAS increase after secondary (biological) wastewater treatment indicating that precursor compounds are …

Our analysis focused on several key factors: ecological integrity, permit acquisition, crowding, parking wait times, and price. Findings reveal that ecological impacts, such as visible signs of litter or vegetative damage, significantly influenced visitor …

Short Analysis Of Emma Watson's 'He For She' Speech, Emma Darocha

Comm-entary

This case study examines power imbalances within organizations. Like many freshmen, a college student in a new state found himself yearning for a sense of belonging. He made the decision to join a fraternity on campus, but this group did not provide him with this sense of community. Instead, he was hazed and left paralyzed from the pledging process. I decided to conduct my case study on a story that involves hazing on a college campus since, regrettably, it still happens frequently in our nation. Having discussions about these situations can help raise awareness and provide information so that no …

Can Listeners Differentiate Varieties Using Prosodic Information? Lect Identification In A Persona-Matching Task, Nicole Holliday, Rachel Steindel Burdin, Paul Reed

Faculty Publications

Sociolinguists and lay people have long been interested in the mechanisms by which dialect and speaker identification occur. The current study aims to test whether realizational differences found in production studies are salient factors in identification of different lects, as well as to examine differences between groups in identification. In this study, listeners were instructed to match clips containing H* and L+H* pitch accents with specific personae who represented speakers of five lects of interest (African American English, Jewish English, Appalachian English, Southern English, and Midwestern English). Listeners from different groups (Appalachian, African American, Jewish, and those who were not …

Direct Precipitation Of Siderite In Ferruginous Environments, A Grengs, G Ledesma, Y Xiong, S Katsev, S W. Poulton, E D. Swanner, C Wittkop

Faculty Publications

Siderite (FeCO 3 ) is often assumed to precipitate from dissimilatory reduction of Fe-(oxyhydr)oxides, but geochemical and mineralogical analyses from ferruginous (anoxic, Fe-rich) Canyon Lake, USA, suggest Fe-carbonate represents a direct early precipitate unrelated to substantial oxide burial.X-ray absorption near edge structure (XANES) spectroscopy of sediment trap materials and an anoxic sediment core indicated a mixture of Fe(II) and Fe(III) in water column particulates and ferruginous surface sediments, while all Mn phases were reduced.About 60 cm below the sediment-water interface, Fe-Mn carbonates were detected by X-ray diffraction and XANES, while Fe extended X-ray absorption fine structure (EXAFS) spectra were best …

Memory And Memoir Writing, Caroline Hanna

The Hugemanities Project Big Contest

My project Memory and Memoir Writing is a 2-3 week unit about students using their media literacy skills to enhance their memoir writing skills. This is a subject that I am passionate about because high school students do not get to write about themselves in the classroom, but will be something that they do in their future. Students will be analyzing a variety of texts, such as, a traditional memoir, a cookbook, and photo essays. Students will be bringing in images and documents from home to supplement and inspire their writing. They will create a finished product that will tell …

Exploring The Impact Of The Aging Effect On Inferred Properties Of Solar Coronal Mass Ejections, F Regnault, Nada Al-Haddad, Noé Lugaz, Charles J. Farrugia, Bin Zhuang, Wenyuan Yu, A Strugarek

Faculty Publications

In situ measurements of coronal mass ejections (CMEs) when they pass over an interplanetary probe are one of the main ways we directly measure their properties. However, such in situ profiles are subject to several observational constraints that are still poorly understood. This work aims at quantifying one of them, namely, the aging effect, using a CME simulated with a three-dimensional magnetohydrodynamical code. The synthetic in situ profile and the instantaneous profile of the magnetic field strength differ more from each other when taken close to the Sun than far from it. Moreover, out of three properties we compute in …

Galactic cosmic rays (GCRs) are charged particles that reach the heliosphere almost isotropically in a wide energy range. In the inner heliosphere, the GCR flux is modulated by solar activity so that only energetic GCRs reach the lower layers of the solar atmosphere. In this work, we propose that high-energy GCRs can be used to explore the solar magnetic fields at low coronal altitudes. We used GCR data collected by the High-Altitude Water Cherenkov observatory to construct maps of GCR flux coming from the Sun’s sky direction and studied the observed GCR deficit, known as Sun shadow (SS), over a …

Ion Heating By A Fast Magnetosonic Turbulence In The Solar Corona, Sergei A. Markovskii, Bernard J. Vasquez

Faculty Publications

Observational data at heliocentric distances of tens of solar radii suggest that fast magnetosonic modes make up a considerable fraction of the solar wind fluctuations. Furthermore, this fraction appears to increase closer to the Sun. We carry out three-dimensional kinetic simulations with particle ions and fluid electrons to evaluate the proton and alpha-particle heating produced by the damping of the fast waves in the solar corona. Realistic parameters at 5 solar radii, including the fluctuation amplitude, are used. We show that, due to the cyclotron resonance, the alphas are heated preferentially perpendicularly to the magnetic field and much more strongly …
