A Love That Harms: Violent Love Imagery In Hadewijch Of Brabant And The Influence Of Richard Of Saint Victor, Kenneth Hoyt

Dissertations (1934 -)

That medieval women mystics utilized violent imagery in regards to Love, and, subsequently, their union with it, is well established in the scholarly literature. The approaches to this imagery differ in their conceptions and approaches to the women: some approach via the influence of courtly literature and thus see it as an expression of a literary genre; others apply more modern critiques, seen in feminist and gender theory approaches, where, usually following Foucault, the emphasis is on how the language effects or disrupts medieval power structures; others approach the women from a historical lens, placing the women’s language as an …

The Tragedy Of Our Trajectory, Marisola Xhelili Ciaccio

Dissertations (1934 -)

In this project, I argue that the trajectory of Western European civilization has resulted in increasingly tragic predicaments that are not to be taken as given features of being human. Though both Ancient Western and Eastern wisdom traditions concur that suffering is a part of life, the point of living is not to suffer but to learn to overcome it and flourish. But because the purported successes of Western “progress” necessarily depend on structural oppression, and oppression produces superfluous sufferings that interfere with our capacities to actualize our freedom and flourish, they ultimately make us all worse-off. Reflecting on such …

A Novel Deep Learning Model For Tool Wear Estimation Of Cutting Tools, Ahmed Darwish

Sustainable Machine Intelligence Journal

In cutting tools, tool wear may result in low-quality surfaces and precision in dimensional measurement. Tool wear may additionally result in fractures and harm to the workpieces over operations. It's critical to track tool wear in life in order to avoid these situations. This research proposes a data-driven deep learning strategy to improve the accuracy of cutting tool wear estimates. This technique combines a Gated Recurrent Unit (GRU) with a Convolutional Neural Network (CNN). In order to circumvent the problems associated with single-domain features that lack appropriate tool status data, a multi-domain combination technique was used to develop candidate features. …

By leveraging the strengths of both convolutional and recurrent neural network components, the proposed models are able to effectively capture spatial …

Mitigation Of Fluoride Contamination In Drinking Water Supply Sources By Adsorption Using Bone Char: Effects Of Mineral And Organic Matrix, Mohamed Raoul Ibrahim, Joshua Akinropo Oyetade, Sadou Dalhatou, Anton Nikiforov, Christophe Leys, Askwar Hilonga

All Rsif Scholars' Publications

This study focused on fluoride (F⁻) contamination of water sources in Bahimi village, Cameroon. After the first investigation, results revealed that all water samples collected had elevated concentrations of fluoride ions (2.3 ± 0.1) mg/L to (4.5 ± 0.2) mg/L above the WHO guidelines (less than 1.5 mg/L). To mitigate the F⁻ levels, the use of bone char (BC) as an adsorbent material was proposed and its performance was tested. BC was prepared from bovine bones at different calcination temperatures (350 °C, 450 °C, 550 °C and 650 °C) and residence times (1 h and 2 h). …

“I Want To Give Back": Examining The Mestiza Consciousness Of Multilingual Rural Latinx Students From California’S San Joaquin Valley, Mayra Puente

The Rural Educator

In 2016, California residents widely supported the passage of Proposition 58, which allowed non-English languages to be used in public education. This proposition was intended to benefit all students, especially the state’s large Latinx K–12 student population, who tend to speak Spanish and English at home and in school. Yet educational resources to support multilingual students in the state’s rural areas are scarce, and students consequently experience “English-only” learning spaces despite progressive educational policy. This article examines the educational experiences of multilingual rural Latinx students from California’s San Joaquin Valley agricultural region using Chicana/Latina feminist pláticas methodology. Drawing on Anzaldúa’s …

Escuchemos Las Voces Bilingües De Nuestros Educadores Rurales: Who And What Matters For The Education Of Secondary English Learners In A Rural Florida School Community, Nidza V. Marichal

The Rural Educator

Guided by constructive epistemology and grounded in Greenwood’s place-conscious education theory and critical race theory in education, (CRT), this narrative-informed qualitative study critically examines how the lived experiences of three bilingual educators shape their work with English Learners (ELs or multilingual learners, MLs) in a Florida rural school community. Primary data consist of videorecorded interviews and photo elicitation that illuminated teachers’ told life narratives. Findings from this study demonstrate that the voices of the bilingual teachers matter for improving EL education in this rural community. The teachers’ reflections about their “ontological-becoming,” their engagement with the rural school community, and the …

Aspirational Mexican American Parenting In The Rural South: Multilingualism, Hard Work, And The Middle Class, Alma D. Stevenson, Scott Beck

The Rural Educator

This study examined the parenting choices of Mexican-heritage former child migrant farmworkers who are now financially stable and raising their own children in the rural South. The study yielded multiple significant findings using data collected during semi-structured, bilingual focus groups and analyzed through grounded theory coding. The participants spoke of painful childhood memories of how their poverty and biculturalism left them isolated. Now, as adults, they have sought middle-class belonging for themselves and their children. They described their “pedagogies of the home” as seeking to preserve their linguistic heritage, teach the value of hard work, and facilitate their children’s upward …

Curriculum Inquiry To Strengthen Teacher Preparation For Supporting Multilingual Learners In Rural Settings, Christiana K. Kfouri, Marjorie W. Rowe

The Rural Educator

Multilingual learners (MLs) represent a substantial, growing segment of the PreK–12 population, including in rural areas. Several forces contribute to the increase of ML students in rural schools (e.g., immigrant labor, refugee crises). As we undergo a major cultural shift from a society that was (misguidedly) viewed as monolingual to one that is now undoubtedly multilingual, many teacher education programs have not sufficiently transformed how they prepare educators for linguistic and cultural diversity. Rural teachers indicate that teacher preparation does not include effective strategies and resources instrumental to meeting the cultural, linguistic, and academic needs of MLs. Moreover, educators may …

Multilingual Educators In Superdiverse Rural Schools: Placing Administrators And Teachers’ Cultural And Linguistic Wealth At The Center Of Rural Education, Carla Paciotto, Gloria A. Delany-Barmann

The Rural Educator

Centered on reconceptualizations of “rural” and “rurality” that reimagine and transcend the “traditional imaginaries” of rural educational settings as places of disadvantage and isolation, this article presents the partial results of a mixed methods study funded by the Spencer Foundation about expanded and pivotal roles played by rural multilingual (ML) teachers, paraprofessionals, and administrators in two rural school districts located in U.S. Midwest COVID-19 hotspots. The pandemic made the historical struggles and inequities that ML students face in U.S. schools glaringly evident, as ML families experienced a disproportionately negative impact of the virus on their health and financial stability and …

School of Nursing and Midwifery

Background: Weight retention between pregnancies is associated with increased risk of perinatal complications, but it is unclear whether there is an association with offspring weight status. This study aimed to determine whether maternal interpregnancy weight change is associated with offspring overweight/obesity, controlling for confounding variables. Subjects/methods: Routinely collected linked data from perinatal and child datasets, in Flanders, Belgium were used. Women having their first and second live births between 2009–2018 were included. The association between maternal interpregnancy weight change and overweight/obesity in the second child at 2 years was examined by logistical regression models. Results: A total of 33,172 women …

Polyphenol-Induced Protein Structural Modifications In Sorghum On Pasting Properties, Annegret Jannasch, Ya-Jane Wang, Sun-Ok Lee, Rohana Liyanage, Zeina Alraawi, Suresh Kumar Thallapuranam, William L. Rooney

Chemistry & Biochemistry Faculty Publications and Presentations

Black sorghum contains a high amount of anthocyanins and proanthocyanidins, whereas white sorghum predominantly comprises phenolic acids. Polyphenols covalently and non-covalently interact with protein, whereas the structure of both compounds affects these interactions. This study investigated the interactions between phenolic acids, anthocyanins, proanthocyanidins and prolamin, which is the major protein fraction in sorghum, and their effect on the pasting properties of white and black, whole and milled sorghum using different chemical agents. Urea increased the pasting viscosity of black sorghum, but not that of white sorghum, indicating that hydrogen bonds and hydrophobic interactions between prolamin and anthocyanins and proanthocyanidins play …

Selective Hydrolysis Of Heterooligosaccharides By Poly(Acrylate) Gel Catalysts, Susanna Striegler

Chemistry & Biochemistry Faculty Publications and Presentations

Natural glycoside hydrolases are distinguished by their ability to hydrolyze glycosidic bonds with high efficiency and selectivity. This feature is achieved through specific interactions in the active site during catalytic turnover and is not just facilitated by two catalytically active amino acids. Intrigued by these features, a biomimetic α-galactosidase mimic was developed using an empirical catalyst design. Starting with a library of 704 gels of which 250 have a unique composition synthesized from TEGDMA cross-linker and 7 selected monomers, 238 monomodal gels are evaluated for their ability to hydrolyze the 1→6 α-glycosidic bond in the disaccharide melibiose. Among those, 13 …

Dartmouth College Master’s Theses

This case study investigates the use of Large Language Models (LLMs) and prompt engineering techniques for data augmentation,in the context of post-trial inter- view data (low-resource natural language data) from a randomized clinical trial on Pain Reprocessing Therapy (PRT) for chronic back pain. The limited sample size from the original study necessitates the generation of synthetic interview samples, needed to draw meaningful inferences from the data and to further extend the study. This study explores the efficacy of various prompting techniques in different approaches such as sentiment inversion and personality-based augmentation. The goal is to elicit desired responses from LLMs …

My Soul, She Walks Behind Me, Sanyukta Shiv Kumar

Dartmouth College Master’s Theses

This thesis reimagines the consequences of my great-grandmother’s life. It is an attempt to demystify women’s conditioned roles within private and public spaces and note how, through this conditioning, their identity is repressed to the point of diffidence and eventually, abhorrence towards their own bodies and the physical spaces they occupy. This is portrayed in poetry form through the voice of my great-grandmother as the primary speaker, and is interspersed with the voices of the grandmother, the mother, and the great-granddaughter.

My great-grandmother’s lived experience consisted mostly of her life as a young wife, mother, devotee, and storyteller. She told …

Challenges Of Using More Precise Temporal And Spatial Resolution Of Remote Sensing Data For Surface Water Quality Monitoring, Ivan Rykin

Dartmouth College Master’s Theses

Monitoring river suspended sediment concentration (SSC) is critical for environmental challenges such as understanding the fate of thawed permafrost sediment and its impact on global carbon cycling. However, traditional SSC monitoring using Landsat imagery is limited by spatial and temporal constraints, particularly for narrow rivers in cloudy and/or snowy regions.

This study investigates the use of higher spatial (3 m) and temporal (daily) resolution satellite imagery from the PlanetScope constellation to estimate SSC in remote rivers such as those in the Arctic. I compare the performance of PlanetScope’s spectral resolution (4 and 8 bands) with Landsat 7. Merging data from …

The Islesboro block is a fault-bounded crustal fragment isolated between the St. Croix and Ellsworth terranes in Penobscot Bay, Maine. We present the results of new geological mapping of the Islesboro 7.5´ quadrangle, which is coupled with new laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS) U-Pb zircon data to support revised unit subdivisions and provide an assessment of the age and provenance of the Islesboro block. Based on these data, the Islesboro block consists of: (1) the Paleoproterozoic–Mesoproterozoic(?) Seven Hundred Acre Island Formation, composed of marble, quartzite, and garnet-mica schist, and intruded by highly retrogressed Neoproterozoic (ca. 670–655 Ma) amphibolite …

The Accurate Conversion Of Biological Experiments From Cesium Irradiation To X-Ray Irradiation: The Significance, Problems, And The Future Of Experimental Radiation Research, Gretchen Carpenter

Dartmouth College Master’s Theses

Preclinical small animal irradiation studies, once conducted on Cesium irradiators, are increasingly being performed with X-ray-based irradiators. The transition stems from concerns regarding national security risks, making X-ray irradiators which are compact and easy to operate an enticing alternative. However, questions regarding the relative biological effectiveness between the two sources have revealed a lack of adequate dosimetric characterization of X-ray beams, standardized protocol for dose calibration, and thorough understanding of experimental biological parameters. A literature review conducted on orthovoltage irradiators has revealed that there are over 54 different types of beam structures used, a dramatic departure from the one uniform …
