Identity Formation Through The Lived Experiences Of Immigrant Muslim High School Students
No full textThe growing number of Muslim students enrolled in U.S. public schools necessitates a more comprehensive understanding of their unique experiences within their educational environments. This phenomenological qualitative study investigated Muslim students\u27 perceptions of their lived experiences in a high school in the Northern Great Plains of the United States. Six Muslim students in their junior and senior years were selected to participate in semi-structured interviews. Through the lens of Bronfenbrenner’s ecological systems theory, this study aimed to deepen understanding of how Muslim students develop their sense of identity and the factors that contribute to this development. The findings revealed that participants’ identities were profoundly shaped by their faith, cultural heritage, and the challenges they faced as immigrants navigating a new environment in both their schools and communities. Students demonstrated their devotion to their Islamic faith and values while struggling with inadequate school accommodations for their religious practices and emotional needs. Their experiences reflected the challenges they face at school and in the community, such as marginalization, misunderstanding, and emotional strain, while also underscoring their resilience, commitment to education and faith, and hope for a better future. Recommendations for stakeholders were offered to better address the needs of the growing number of Muslim students enrolled in public schools in the Northern Great Plains
Anatomical Signatures: How Individual Tissue Patterns Shape Recovery Response To Support Surfaces
No full textBackground: Pressure injuries affect millions of people annually, despite the widespread use of preventive technologies such as alternating pressure air mattresses. However, systematic reviews find inconclusive evidence for their effectiveness. Current assessment methods capture only single-point measurements or static snapshots, missing the spatial-temporal complexity of tissue responses to support surfaces.Objective: Determine the efficacy of an APAM by utilizing a multi-modal optical imaging approach to assess spatial-temporal tissue responses to different support surfaces.
Methods: A multi-modal imaging device, combined with laser speckle contrast imaging for perfusion assessment and reflectance spectroscopy for oxygenation measurement, was applied to study tissue responses after a participant lay across three support surfaces: foam, gel, and APAMs. Analysis methods varied from correlation-based assessment to k-means clustering of temporal patterns, integrating several to create a tissue state classification.
Results: Integration of perfusion and oxygenation parameters revealed 48 distinct physiological states representing different tissue recovery conditions. Spatial analysis of these states uncovered the anatomical signature , individual-specific recovery patterns that persisted across all three surfaces. While foam and gel surfaces showed clear expression of these patterns, APAMs modified but did not eliminate them, particularly along channel architecture. Individuals demonstrated consistent within-person patterns but also showed between-person variation, suggesting that underlying anatomical structures, tissue vulnerability, and recovery.
Conclusions: This research introduces the concept of anatomical signature, demonstrating that tissue recovery follows individually characteristic patterns, likely determined by anatomical variations in bone proximity, vascular architecture, and tissue composition. APAMs appear to work by modifying rather than eliminating these patterns. These findings suggest the need for personalized strategies based on an individual\u27s anatomical pattern
Mudstone Deposition From Continental To Shallow-Marine Realms— Examples From The Triassic Of Western North America
No full textMudstones are a major component of red-bed unit deposition in western North America during the Permo-Triassic but have remained understudied due to their lack of economic importance and general lack of attention toward the redbeds themselves. Analysis of fine-grained sediments—including depositional features and fossil content—is crucial for resolving questions regarding the accumulation of such red beds but has remained underutilized. This dissertation thus focuses on red-bed deposits from the Permo-Triassic transition in western Laurentia. The first chapter focuses on the Torrey Member of the Moenkopi Formation, which represents the concurrent evolution of three deltaic systems in present-day Utah. Analysis of the mudstone revealed that deposition in the intertidal zone is defined by suspension settlement, whereas bedload transport dominates in the distal delta. Supratidal mudstone is often “cannibalized” from the intertidal zone or is deposited by flooding of the fluvial system. The vertical distribution of mudstone facies, combined with detailed stratigraphic correlations of unit outcrops, demonstrates that the deposition of the Torrey Member occurred in a single sequence.
The second chapter is a thorough redescription of the Permo-Triassic Spearfish Formation in the Williston Basin. The analysis of mudstone and siltstone sections in the unit presented direct fossil evidence—in the form of Tasmanites—that sediments of the Spearfish Formation record the cyclical growth and evaporation of an epeiric sea with high sediment runoff from the continent. This results in the accumulation of strata that superficially resemble continental deposits, highlighting the dangers of assuming depositional settings based solely on unit color. Fossil content also suggests that deposition occurred during the Late Permian throughout the study area. The Permo-Triassic boundary is placed on stratigraphic and paleontological grounds at the base of a salt bed two-thirds above the unit’s lower contact.
The final study presents a description of various rip-up clasts in low-color-contrast settings, primarily from the Moenkopi and Spearfish formations, supplemented by black shale deposits of the Bakken and Alum formations. These findings revealed that rip-up clasts are more abundant than previously believed and identify a new clast habit that is most strongly associated with intertidal and supratidal mudstones
Application Of Evolved Gas Analysis And Thermal Desorption–pyrolysis Gas Chromatography Mass Spectrometry For Detection And Identification Of Per- And Polyfluoroalkyl Substances In Building Materials And Chemical Characterization Of Representative Vehicle Brake Pads
No full textTwo projects are presented in this work:
First, Per- and polyfluoroalkyl substances (PFAS) are synthetic fluorinated organic chemicals, which have been widely used in many consumer products. While some PFAS, like perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), have been restricted due to their negative impacts on human health and the environment, the issue remains a global concern because there are thousands of other PFAS chemicals still in use. In this work, we report the detection of phthalates and volatile PFAS in building materials, identified through an optimized thermal extraction protocol; evolved gas analysis-mass spectrometry (EGA-MS) and thermal desorption-pyrolysis-gas chromatography with mass spectrometry (TD-Pyr-GC-MS). EGA-MS was used for thermal profiling of the materials, differentiating volatilization, i.e., thermal desorption, and thermal decomposition via pyrolysis. Several tested materials showed the occurrence of PFAS related ions at the TD step (150–300 °C) and Pyr step (300–400 °C), suggesting the presence of PFAS. Multi-step temperature programs for TD-Pyr-GC-MS were then developed based on EGA-MS screening. The TD-Pyr-GC-MS results showed detection of perfluoroheptene in all samples at the TD step except for the outer layer of fiberglass analyzed. One metal frame was found to contain PVDF (polyvinylidene fluoride), a fluoropolymer. All window screen samples were found to contain phthalates, a class of plasticizers known for adverse environmental and human health effects. EGA-MS and TD-Pyr-GC-MS proved effective for rapid screening and simultaneous determination of volatile, semi-volatile, and non-volatile chemicals of concern, including PFAS, in complex environmental matrices.
Second project: Due to increasingly strict regulations on exhaust emissions from road traffic, their contribution to the total emissions has decreased in urban areas. In contrast, non-exhaust emissions such as those from vehicle brake pads are less regulated yet make up a proportion of total road traffic emissions in urban areas. To characterize the thermal evolution and breakdown profiles of six representative vehicle brake pads, this research employed evolved gas analysis-mass spectrometry (EGA-MS) and thermal desorption–pyrolysis–gas chromatography with mass spectrometry (TD-Pyr-GC-MS). The EGA-MS results yielded thermal profiles of evolving species, revealing threshold temperature in these materials with thermal breakdown typically occurring between 200 and 750 °C. Furthermore, profiles of selected ions obtained with MS enable early prediction of evolving species. Applying the identified temperatures to TD-Pyr-GC-MS analysis, we identified aromatics, nitrogen-containing compounds, polycyclic aromatic hydrocarbons (PAHs), phthalate, sulfur-containing compounds, and oxygenates evolving within the TD step. The Pyr step revealed the presence of nitrogen-containing compounds, aromatics, alkenes, alkenes, alkanes and oxygenates. With braking temperatures usually between 100 and 500 °C, the results suggest that brake pad emissions contribute to global emissions through the release of VOCs and particulate matter (PM) into the atmosphere, formation of secondary organic aerosol (SOA) formation or the dispersal of contaminating brake dust into soil and water. Although some of these compounds may not be of immediate concern, they can further contribute to the formation of other chemicals, such as disinfectant by-products (DBPs) by serving as precursors. More strict non-exhaust emission controls and the development of high-performance brake pads that reduce environmental and health risks are therefore desirable
Toward An Anthropological Ecocriticism
No full textEnvironmental storytelling has increasingly reckoned with concepts and assumptions about (N/a)ture inherited from the Western intellectual tradition. The late 2010s and early 2020s in particular have seen an explosion of fiction that interrogates the limits of these past ideas. Relatedly, ecocriticism of this period has entered a self-reflexive mode that has sought to deal with its own limitations while offering insights that may prove generative for a more general audience of environmentally minded readers. This project adds to ongoing ecocritical discourse by tracing a series of implicit affinities between the broad traditions of anthropology and environmental fiction through their shared interest in radical, frequently optimistic, politics. These affinities form the basis for what I term an “anthropological literary criticism” that takes lessons from real-world scenarios and juxtaposes them with fictional works that grapple with similar questions. Through close readings of Ursula Le Guin’s The Left Hand of Darkness, Richard Powers’s Bewilderment, and Kim Stanley Robinson’s New York 2140, I propose three tenets of this literary criticism as applied to environmental novels. First, this criticism operates under the belief that the social systems of a given time and place are not the product of an inevitable, linear evolution toward industrial state capitalism. Second, such a lens offers a detailed deconstruction of how these now destabilized ideas have operated in fictional worlds while gesturing toward new understandings on the cusp of emergence. And third, by holding as its unifying principle a belief in the malleability of individual persons and their composite communities, an anthropological ecocriticism refuses narratives of doom while looking toward the future with a kind of empowering hope
The Impacts Of Hydrometeor Centrifuging On Numerical Simulations Of Supercells And Tornado-Like Vortices
No full textSupercell simulations capable of resolving a tornado-like vortex (TLV) have typically ignored hydrometeor centrifuging, resulting in the unrealistic buildup of precipitation in the center of TLVs. To improve the realism of numerical simulations of supercells and their resulting TLVs, an algorithm to parameterize bulk hydrometeor centrifuging was incorporated into an idealized cloud model. Simple idealized vortex simulations and simulations of supercells producing TLVs were analyzed to determine the impacts of hydrometeor centrifuging on numerically simulated supercells and TLVs. The inclusion of hydrometeor centrifuging does not appear to directly impact the intensity and duration of supercell spawned TLVs. Although precipitation minima developed in the center of the simulated TLVs, consistent with radar observations of tornadoes, no significant direct effects on simulated TLV intensity and duration were observed. For the parent simulated supercells, however, stronger updrafts and downdrafts were observed when hydrometeor centrifuging was included. It is possible that these changes to updraft and downdraft intensity could ultimately impact TLVs associated with the simulated supercells, but many more cases and ensemble simulations would be required to determine this
