Eavesdropping On Killer Whales: Distribution, Calling Rates, And Acoustic Abundance Of Fish-Eating And Mammal-Eating Killer Whales In The Gulf Of Alaska, Hannah J. Myers

Marine Biology

The widespread loss of apex consumers in marine, terrestrial, and freshwater ecosystems throughout the world has precipitated profound trophic cascades and switches to different ecological states. However, conserving top predators can deliver broad biodiversity benefits and improve ecosystem resiliency. Effective conservation and management policy is predicated on a species' distribution and abundance in a given area and time. In this dissertation, I provide new insight into killer whale (Orcinus orca) distribution, vocal behavior, and abundance in the Gulf of Alaska using passive acoustic monitoring and advance long-term monitoring capacity for this species. First, I describe the year-round spatiotemporal distribution and …

The major issue arises when these images must be captured at depths greater than 500 feet and artificial lighting needs to be provided. Efficient algorithms and models …

Microplastics In Spotted Seal Stomachs From The Bering And Chukchi Seas In 2012 And 2020, Alexandria Sletten

Biological Sciences

Microplastics pose a significant threat to marine ecosystems across multiple trophic levels. Spotted seals (Phoca largha) are piscivorous and occupy one of the higher trophic positions in the Bering and Chukchi seas, putting them at risk of ingesting microplastics through prey. This project aimed to determine if microplastics are present in the stomachs of spotted seals harvested for subsistence purposes and compare their presence spatially between two harvest locations, Gambell and Shishmaref, AK. Microplastics are predicted to increase in the Arctic over time due to climate warming and subsequent deposition of microplastics from melting sea ice. Therefore, we examined stomachs …

The Effect Of Cold Exposure And Activity On Skeletal Muscle Physiology: A Study Of Human And Animal Models, Michelle M. Johannsen

Biological Sciences

Environmental factors and physical activity have the potential to modulate skeletal muscle physiology in beneficial ways. Cold exposure and endurance exercise, specifically, may improve aerobic capacity and atrophy resistance. I utilized three models to examine the effect of cold exposure and activity level on skeletal muscle physiology: quantitation of body composition and energy expenditure estimates in humans participating in a transmountain race, comparative proteomic analysis of skeletal muscle in hibernating and summer active American black bears (Ursus americanus), and an experimental study of the combined effects of cold exposure and endurance training on white adipose tissue, and gastrocnemius and soleus …

Smoke Without Fire: Wildfire Smoke Affects Phenolic Composition Of Wild Blueberry Fruits (Vaccinium Uliginosum), Laura G. Weingartner

Biological Sciences

Wildfire smoke can induce changes in plant growth, phenology, and chemical composition. The frequency and intensity of wildfires have increased over the last thirty years in Alaska, and smoke has the potential to affect important wild fruit plants, such as bog blueberry (Vaccinium uliginosum L.), a food source for many Alaskans and wild animals. We exposed bog blueberry plants to wood smoke at different stages in fruit development: early-season when the plants were flowering ("early-smoked"), mid-season when fruits were unripe ("mid-smoked"), and late-season when fruits were fully ripe ("late-smoked"). We measured anthocyanins, proanthocyanidins, and total phenolics in the ripe fruits, …

Effects Of Desformylflustrabromine On Compulsive-Like And Social Behaviors In Mouse Models Of Ocd And Autism, Isaac Van Flein

Biological Sciences

Obsessive-Compulsive Disorder (OCD) and autism spectrum disorders (ASD) share a number of similar deficits, including altered cholinergic activity in the central nervous system (CNS), manifestation of repetitive, restricted, and compulsive-like patterns of behavior, and frequent co-morbid presentation. Desformylflustrabromine is a novel positive allosteric modulator of α4β2 nicotinic acetylcholine receptors, which has recently been shown to be able to reduce compulsive-like behavior in a non-induced mouse model of OCD. In this study, I attempted to replicate the compulsive-like behavior-reducing effects of desformylflustrabromine in the mouse model of OCD, as well as expose the model to a novel assessment; social behavior, as …

This thesis introduces settling chambers and water spray as feasible techniques commonly used for controlling dust in underground mine operations. The research aims to provide a low capital cost and maintenance-free system to capture the dust particles upwind of the main fan. The research focuses on an underground polymetallic mine in Peru, serving as a …

Making Space For Adolescents Of Refugee Background In Public Libraries, Danielle S. Dejonge

Masters Projects

Refugee adolescents go through multiple transitions that affect identity while settling in their new country of relocation. The ability to recognize the complexity of identity in a healthy way is fostered by safe spaces of belonging that encourage agency. Libraries, as spaces already effectively serving diverse populations including refugee youth, have the resources to be a safe space for these adolescents. One resource that has been trending in libraries is a makerspace. Makerspaces offer multimodal activities, whether they be arts-based or STEM-based, that not only encourage critical thought, but also allow for development of belonging and agency for healthy dynamic …

Model-Based Estimation Of Juvenile Salmon Spatial Ecology In The Eastern Bering Sea, Alaska, Lilian Hart

Fisheries

Quantitative descriptions of juvenile salmon spatial ecology during the marine phase of their lifecycle are needed to help direct conservation efforts and uncover latent relationships between juvenile salmon and their environment. The NOAA Fisheries Essential Fish Habitat (EFH) program contributes to the conservation of species in the marine waters off of the coast of Alaska by identifying areas of particular importance to reproduction and growth. Salmon EFH definitions have not yet been updated using the species distribution modeling approach taken most recently in defining Alaska groundfish and crab EFH. Current EFH definitions for Alaskan salmon are geographically broad, do not …

Rare Presentation Of Postpericardiotomy Syndrome After Left Atrial Myxoma Removal, Jessy Feng, Shyama Appareddy, Yaman Gibran, Aryana Garza, Jacqueline Luevano, Gustavo Garcia

School of Medicine Publications

Postpericardiotomy syndrome (PPS) is a known complication of cardiac valve surgery, but it has not been commonly reported as a postoperative complication of cardiac myxoma removal. A 78-year-old female with hypertension and atrial fibrillation presenting with angina was found to have a large left atrial myxoma (7.5 cm × 4.4 cm). The myxoma was resected; however, 1-week postoperation hemoglobin and blood pressure decreased with elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). Limited transthoracic echocardiogram (TTE) showed moderate pericardial effusion, confirming the diagnosis of PPS. This case highlights the importance of monitoring patients postremoval of myxoma for symptoms of …

Organizational Effectiveness Of Athletic Departments And Coaches’ Extra- Role Behaviors, Claudio M. Rocha, Brian A. Turner

Journal of Issues in Intercollegiate Athletics

The objective of the current study was to explore and describe the relationship between coaches’ extra-role behaviors (precisely organizational commitment – OC and organizational citizenship behavior – OCB) and the organizational effectiveness (OE) of athletic departments. OC was measured through 12 items that represent its three dimensions: affective, normative, and continuance commitment (Meyer, Allen, & Smith, 1993; Turner & Chelladurai, 2005). OCB was measured using five items that represent its three dimensions: sportsmanship, civic virtue, and helping behaviors (Podsakoff & Mackenzie, 1994). Following the current tendency in the literature (Cunningham, 2002; Putler & Wolfe, 1999; Smart & Wolfe, 2000), OE …

Collegiate Sport Chaplaincy: Problems And Promise, Steven Waller, Lars Dzikus, Robin Hardin

Journal of Issues in Intercollegiate Athletics

Sport chaplaincy has been evolving since the latter half of the twentieth century, and many professional teams and professional organizations utilize the services of chaplains. Several licensing and credentialing organizations do train chaplains, counselors and mentors, but they are not necessarily aimed at sport chaplains. Chaplains have become more prominent in collegiate athletics as well and as such several training programs have developed for collegiate sport chaplains. Collegiate institutions, parachurch organizations and nonprofit faith-based organizations offer the programs that do exist. However, in collegiate athletics there is no governing body that oversees the training requirements or qualifications of chaplains. This …

Should Environmental Protection Be Through Anthropocentric Rights?, Christen Maccone

Pace Environmental Law Review

Environmental constitutional rights are increasingly used as a strategy to protect the environment, with more than seventy countries acknowledging environmental rights in their constitutions. However, constitutions are inherently anthropocentric, making environmental rights created therein of- ten inseparable from human rights. This paper will examine how environ- mental constitutional rights are insufficient due to the anthropocentric nature of constitutions and argue for the need for a more biocentric approach.

The Constitutional Public Trust In A Warming World, Sean Lyness

Pace Environmental Law Review

The public trust doctrine—a state-specific doctrine that entrusts certain natural resources to the state to hold for the public—most often exists as a common law doctrine. But a handful of states have constitutionalized their version of the public trust. A growing body of jurisprudential evidence shows the constitutional public trust in action—or not—against climate change. This Article examines these cases brought by governmental plaintiffs—states and local governments—investigating whether constitutionalizing the public trust has made a difference. Although the results are nascent, early signs suggest that a constitutional public trust can result in more comprehensive and aggressive law- suits when wielded …

Reading Between The Lines Of The Ira + Iija Power Gaps, Steven Ferrey

Pace Environmental Law Review

Two major pieces of legislation enacted during the Biden Administration – the 2021 Infrastructure Investment and Jobs Act (IIJA) and the 2022 Inflation Reduction Act (IRA) – devote hundreds of billions of dollars over the next decade to rapidly increase electrification throughout the United States. While this legislation provides substantial investment in infrastructure, it also demands action from different legal regulators. Renewable energy occupies a much larger land footprint than traditional electric power production. And land-use under the Tenth Amendment is within local and state, rather than federal, jurisdiction. To date, U.S. local land use regulation frustrates such national legislation. …

The Green Amendment: Assessing The Latest Tool In The Environmental Tool Belt, Carolyn Drell, Mia Petrucci

Pace Environmental Law Review

In the new edition of Maya K. van Rossum’s book, The Green Amendment: The People’s Fight for a Clean, Safe, and Healthy Environment, she presents the case for adopting green amendments protecting environmental rights into state constitutions and the Federal Constitution. This book review examines van Rossum’s arguments and raises legal concerns that prevent green amendments from providing a silver bullet solution to environmental harms. Despite these concerns that will likely resonate with practitioners, van Rossum increases the accessibility to the topic of green amendments for a wider audience, which is ultimately a net win for environmental advocacy.

The Impact Of Emma: Destroying Stereotypes Through Nuanced Characters In Text And Film, Julia Mccool

English MA Theses

This paper explores Jane Austen’s Emma as a response to stereotypes in 18th century novels and moral tales, and Autumn De Wildes’s Emma. from a feminist lens. Examining both of these works reveals that Emma was originally, and still is over 200 years later, transforming stereotypes in literature and film adaptations. The novel seems to be responding to a common stereotypical female villain found in many 18th century novels. In viewing Emma as a subversion of this stereotype, it is clear that Austen was responding to the sexist notions behind the character type, and writing a heroine more in line …

Cost Minimization For Charging Electric Bus Fleets, Daniel Mortensen, Jacob Gunther, Greg Droge, Justin Whitaker

Electrical and Computer Engineering Student Research

Recent attention for reduced carbon emissions has pushed transit authorities to adopt battery electric buses (BEBs). One challenge experienced by BEB users is extended charge times, which create logistical challenges and may force BEBs to charge when energy is more expensive. Furthermore, BEB charging leads to high power demands, which can significantly increase monthly power costs and may push the electrical infrastructure beyond its present capacity, requiring expensive upgrades. This work presents a novel method for minimizing the monthly cost of BEB charging while meeting bus route constraints. This method extends previous work by incorporating a more novel cost model, …
