Combining Alaska Forage Fish Data From Research Surveys And Predator Diets To Assess Forage Fish Response To Climatic Regime Shifts, Lindsay Turner

Fisheries

Forage fish play a crucial role in the marine ecosystems of Alaska through the transfer of energy from lower trophic levels to marine predators. Understanding and quantifying Alaskan forage fish responses to rapid climatic shifts is needed to inform adaptive management strategies under a warmer and more variable future in Alaska. However, data on the occurrence and abundance of forage fish in Alaska are limited due to the diversity of life history strategies and patchy distribution that make their capture in fisheries-independent surveys difficult. In this thesis, I address current gaps in the data available on forage fish through the …

We focused on 1013 InDels of at least 10 bp for further analysis, representing 1.61% of the total reads, with a distribution of 832 insertions and 181 …

The Imposition Of Power: Modernity And Nature In Hemingway And Mccarthy, Danielle Ball

Honors College Theses

This thesis focuses on the role of nature in opposition to modernity in Ernest Hemingway's “The Last Good Country” and “The End of Something” as well as Cormac McCarthy’s The Orchard Keeper. Each author places the forces of modernity, such as the logging industry or the introduction of the railroad, at odds with the untouched state of the natural world. Specifically, I emphasize the different portrayals of the natural world from each author. Hemingway’s nature is very closely tied to Romanticism, as nature is a spiritual and healing force for those who choose to commune with it. However, McCarthy portrays …

Seismic Site Response, Liquefaction-Induced Lateral Spreading And Impact Of Seasonal Frost On Pile Foundations In Cold Regions, Yue Zhao

Engineering

Permafrost sites are experiencing significant changes due to anthropogenic activities and climate change, leading to substantial variations in soil dynamic properties and increased seismic risks. The associated geohazards, including differential settlement, slope instability, and liquefaction of degraded, unconsolidated materials in seismically active warm permafrost regions, pose substantial threats to the built infrastructure. This study aims to assess the seismic site response of warm permafrost sites and analyze the impact of seasonal frost on liquefaction-induced lateral spreading and pile foundation behavior in cold regions. Northway Airport, Alaska, was used as the study site to characterize permafrost conditions, while the Slana River …

Developing A New Liquefaction Ejecta Prediction Model Considering Soil Properties Of Non-Liquifiable Surface Layers Using New Large Database From The 2012 Emilia Romagna, Italy Earthquakes, Jonah Bradley Dundas

Theses and Dissertations

The presence of a non-liquefied crust overlying a liquefied layer has been found to have a significant effect on sand ejecta and surficial liquefaction damage, as observed by Ishihara (1985). Following the 2010-2011 Canterbury seismic sequence in New Zealand, almost no foundation deformation occurred in areas with liquefaction susceptible soils overlain by at least a 3 meter thick crust [1]. In contrast, the 2012 Emilia-Romagna earthquake in Italy provided surface evidence of liquefaction despite 6+ meter thick crusts. Several researchers have proposed liquefaction prediction models [e.g. LPI [2], Ishihara Curves [3], LSN [4], LPIISH [5] and the methods proposed by …

Meaning As Process And Product: Hybridizing Metamodern Hylosemiotics With Postmodern And Contemporary American Poetry, Zeke Shomler

English

This thesis expands on Jason Storm’s theory of metamodern hylosemiotics by addressing contemporary American poetic strategies and their relationship to modernism and postmodernism, especially through Cole Swenson and David St. John’s definition of the “American hybrid.” In modifying Storm’s theoretical system, I offer a hybridized semiotics that locates meaning both in the information or “content” inferred through the act of reading and the related processes of interacting with the text. Through readings of poetry by John Ashbery, Terrance Hayes, Clark Coolidge, and William Stafford, I show that hybridizing semiotics is not only necessary for the consistency and viability of metamodern …

The Activity And Origin Of The Chitinases In The Gut Of The Mediterranean House Gecko, Alec John

Masters Theses (Archived)

Chitin is a major component of the exoskeleton of arthropods as well as the cell wall of fungi. This amino polysaccharide polymer provides structure and protection to these organisms and represents a significant barrier to digestion of arthropod prey and fighting fungal infections. Chitinases are enzymes that break down chitin. Smaller insectivores, based upon the higher surface-to-volume ratio of their even smaller prey, ingest a large amount of chitin per unit prey item. Therefore, they represent high-likelihood opportunities to bio prospect for novel chitinases that may be effective against pathogenic fungi. Fungal infections are notoriously difficult to treat, and they …

The Lived Experiences Of Poverty Among Particularly Vulnerable Tribal Groups In A Rights-Based Anti-Poverty Programme In Jharkhand India, Monimala Sengupta

Lingnan Theses (MPhil & PhD)

This research explores poverty and social exclusion among Primitive Tribal Groups (PVTGs) in India using T. H. Marshall's concept of social citizenship. With evidence showing a disproportionate burden of poverty in the Global South, indigenous groups are even overrepresented among the poor. India, home to one of the largest Indigenous populations, accounts for 70% of South Asia's impoverished, but the specific nature of poverty within these communities remain poorly understood.

Over the past two decades, India's national response to poverty has shifted towards rights-based, inclusive policies targeting marginalised communities such as Dalits, Scheduled Castes, and Scheduled Tribes, historically subjected to …

Pmp2+ Scs Maintain The Survival And Functioning Of Large-Caliber Motor Axons, Mikolaj Kozlowski

Arts & Sciences Graduate Student Theses and Dissertations

Neurodegenerative diseases are characterized by selective neuronal vulnerability, a phenomenon in which a specific pathology induces the death of a particular subpopulation of neurons. For example, selective neuronal vulnerability in the peripheral nervous system results in sensory, motor, or mixed peripheral neuropathies. While the intrinsic differences between neuronal subtypes cannot fully explain the basis of selective neuronal vulnerability, it is plausible that it partially stems from neuron extrinsic mechanisms such as the malfunction of distinct Schwann cell (SC) subtypes. Recently, we identified an exciting subpopulation of myelinating SCs characterized by the expression of Adamtsl1, Cldn14, and Pmp2 (hereafter referred to …

Sustainable Plastics From Plastic Metabolisms: Leveraging Purple Non-Sulfur Bacteria For Polyhydroxyalkanoate Synthesis, Eric Michael Conners

Arts & Sciences Graduate Student Theses and Dissertations

Purple non-sulfur bacteria (PNSB) are a taxonomically diverse group of gram-negative bacteria representing some of Earth’s most metabolically versatile life, with many genera capable of switching between the four major metabolic modes – chemoheterotrophy, chemoautotrophy, photoheterotrophy, and photoautotrophy. Today, we exploit this diversity to explore fundamental questions about microbial metabolism. At the same time, many researchers are eager to use PNSB as tools for biotechnological innovations. Yet there exists a gap between fundamental biology and applied science. Part of the challenge is that we rely on a handful of model organisms – namely, members of the genera Rhodopseudomonas and Rhodobacter …

The C-Terminal Activating Domain Promotes Pannexin 1 Channel Opening, Erik Henze, Jacqueline J Ehrlich, Janice L Robertson, Eric Gelsleichter, Toshimitsu Kawate

2020-Current year OA Pubs

Pannexin 1 (Panx1) constitutes a large pore channel responsible for the release of adenosine triphosphate (ATP) from apoptotic cells. Strong evidence indicates that caspase-mediated cleavage of the C-terminus promotes the opening of the Panx1 channel by unplugging the pore. However, this simple pore-plugging mechanism alone cannot account for the observation that a Panx1 construct ending before the caspase cleavage site remains closed. Here, we show that a helical region located immediately before the caspase cleavage site, referred to as the "C-terminal activating domain (CAD)", plays a pivotal role in facilitating Panx1 activation. Electrophysiology and mutagenesis studies uncovered that two conserved …

Journal of Critical Race and Ethnic Studies

This qualitative study explores the transformative potential of counterstory as a method for promoting educational equity through the lens of racial literacy and the "Archeology of Self" framework. Rooted in critical race theory, counterstory enables marginalized voices to challenge and reshape dominant narratives within educational research and practice (Delgado & Stefancic, 1996; Delgado, Stefancic, & Harris, 2012; Ladson-Billings, 2013; Ladson-Billings, 2021; Martinez, 2020). The community-based study using a counter-storytelling approach draws on data from a focus group held during the 2024 Voices of Empowerment Conference, part of the Institute for Critical Race and Ethnic Studies (CRES) at St. John's University. …

Should We Clear The Cobwebs In Our Minds Or Dismantle Racial Structures? Reflections On The Lack Of Critical Thinking Of Higher Education Staff In The Uk, Chrissie Da Costa

Journal of Critical Race and Ethnic Studies

Higher education in the UK constantly emphasises  critical thinking for students. However, analysis of comments made about *Black students and staff indicate that some academic staff fail to critically analyse their thoughts, words, and deeds. This paper sets out to analyse these utterances of HE staff and to investigate whether they actively reproduce and are intended to reproduce racist practices in HE, which could affect the experience, performance, and confidence of some of these students and staff who identify as Black and Global Majorities.  Applying critical race theory and socio-ideological analysis of language (Bakhtin 1981 and Voloshinov 1973) to analyse …

Breaking News: The Presence Of The White Racial Frame In Partisan Cable News Networks’ Coverage Of Officers Killing Black Victims, Andrea C. Smith, Jonathan M. Cox

Journal of Critical Race and Ethnic Studies

This study analyzes how two of the most popular and partisan cable news networks in the U.S., FOX and MSNBC, framed victims and officers in their coverage of cases where officers kill Black men. In addition, this work investigates how these networks discuss systemic racism. Using Feagin's white racial frame as a framework and critical discourse analysis as an analytical tool, the findings show that both networks exhibited anti-Black and pro-White framing within their reports. However, how these frames manifested differed across the networks, displaying differing similarities. Most notably, when counter-framing was present on MSNBC, they still perpetuated the anti-Black …
