Vitas: A Visual Exhibit, Ilisa A. Walter Dec 2020

Vitas: A Visual Exhibit, Ilisa A. Walter

Art

VITAS is a visual exhibition that addresses the idea of a posthumous legacy. The substance of a person’s life is composed of what they’ve done, and what they become after death is determined by that substance. This exhibition is composed of 25 carved animal skulls and sculptures inspired by the concept of vitas, treating life as an opportunity to advance the next generation through life’s work. VITAS studies the idea of what happens after the passing of a being by applying embellishment, adornment, pigments, and carvings onto the skeletal remains of animals. By applying human influence to natural material, the …

Palestinian Women’S Agency, Yasmin Khodary Dec 2020

Palestinian Women’S Agency, Yasmin Khodary

Political Science

In Civil Resistance and Conflict Transformation, Veronique Dudouet divides responses to oppression into two main analytical categories. The first category refers to conventional actions, including party politics, advocacy or diplomacy, dialogue and negotiations, and litigation. The second category is non-intuitional/contentious actions including: first, nonviolent/unarmed/peaceful resistance through protest and persuasion, non-cooperation, disruptive intervention and creative resistance and second, violent/armed resistance through warfare, terrorist attacks, guerrilla insurgency, protest violence and sabotage. These two sub-categories of resistance operate outside the bounds of conventional political channels and are usually employed by an oppressed minority or disempowered majority by an exclusionary national or foreign actor. …

Integration Of Remote Sensing Technologies Into Arctic Oil Spill Response, Jessica I. Garron Dec 2020

Integration Of Remote Sensing Technologies Into Arctic Oil Spill Response, Jessica I. Garron

Interdisciplinary Studies

Identifying the tools and pathways to successful integration of landscape level science into decision-making processes is vital for quality environmental stewardship. Remote sensing information can provide critical facts to decision makers that historically were only available via manned airplane flights and ground truthing expeditions. Remote locations like the Arctic are well suited for monitoring with remote sensing tools due to the lack of transportation infrastructure and communications bandwidth. Remote sensing tools can be valuable when monitoring specific Arctic targets like ocean going vessels, sea ice, coastal erosion, off-shore resource development infrastructure, and oil spills. This dissertation addresses how to mount …

Metabolite Influence On The Hibernating Arctic Ground Squirrel, Sarah A. Rice Dec 2020

Metabolite Influence On The Hibernating Arctic Ground Squirrel, Sarah A. Rice

Chemistry and Biochemistry

Hibernation is a state of extreme metabolic plasticity and fasting. How hibernators maintain nitrogen homeostasis and regulate amino acid metabolism and how those metabolites influence hibernation physiology remains unknown. We first utilized three approaches to understand nitrogen homeostasis and amino acid metabolism in hibernation: longitudinal metabolic profiling within individual animals over undisturbed torpor, in vivo amino acid isotope tracing in deep torpor, and ¹⁵N isotope tracing in vivo during arousal from hibernation in Arctic Ground Squirrels (AGS). We observed that in vivo whole body production (WBP) of metabolites in deep torpor are profoundly and selectively suppressed in deep torpor. Metabolic …

A Place-Based Study Of Alaskan Animals, Emma Heslop Dec 2020

A Place-Based Study Of Alaskan Animals, Emma Heslop

Education

In the spring of 2020, my second-grade class, located in Fairbanks, AK, dived into a place-based exploration of Alaskan animals. The aim of the project was to increase students’ connections and understanding of the state where they live (Alaska) and the animals that they share it with. Through a backwards design, inquiry-based instructional model, my students met state standards with an integrated-subject approach. With art, guest speakers, research, and field trips my students learned about the Animals that share Alaska with us, their environments, and their adaptations. Students used informational writing published on digital mediums to share their knowledge with …

The Ranch(Er), Wendy Connelley Dec 2020

The Ranch(Er), Wendy Connelley

Art

THE RANCH(ER) is a thesis project to fulfill the requirements of an MFA degree in visual fine-arts. This project focused on exploring my connection between the land, the ranch and its tools, and generations of ancestors living and working a small family ranch. I give voice to the seldom-vocal rancher and the isolation, hardships, and tenderness of ranch life. I have chosen as subjects for this exhibition objects that are utilitarian and are items woven into the cultural fabric of ranchers and their families. They are icons of generational identity. Rather than creating purely traditional functional objects such as cups …

Legacy Junk: Mfa Other Exhibition, Allison Juneau Dec 2020

Legacy Junk: Mfa Other Exhibition, Allison Juneau

Art

I recently purchased a tract of raw land with the intention of building a cabin, and wasn't terribly surprised to find the land came with some impressive piles of junk. I was frankly enamored of these objects, abandoned but not destroyed by the previous owner. They had a potentially useful quality that resonated with other aspects of the Fairbanks community; transfer sites, the airplane graveyard behind the airport, old couches and tables and wooden spools that littered the yards of countless homes. This rural detritus represents a confluence of natural and cultural forces that Alaskans experience every day. I wish …

The Yup'ik Relationships Of Qiluliuryaraq (Processing Intestine), Ellen Carrlee Dec 2020

The Yup'ik Relationships Of Qiluliuryaraq (Processing Intestine), Ellen Carrlee

Anthropology

This project explores multiple Native cultural contexts that intersect in the use and understanding of intestine. Gut (tissues of internal organs including stomach, intestine, bladder and esophagus) as a raw material was historically used by many circumpolar cultures to make items like drums, raincoats, hats, windows, sails, containers, and hunting floats. These items are abundant in museum collections, but rarely seen today in cultural practice or the art market. Intestine is a natural material that was replaced by synthetic materials, but its dual physical properties of protection and permeability are the only features replicated by plastics. Examination of intestine as …

Ethnoarchaeology Of The Middle Tanana Valley, Alaska, Gerad M. Smith Dec 2020

Ethnoarchaeology Of The Middle Tanana Valley, Alaska, Gerad M. Smith

Anthropology

This study explores the shifting anthropological constructs of identity for the Middle Tanana people through time. It first summarizes this theme through contemporary regional Native American internal and external influences. A discussion is then given on how these constructs became formed through historical processes. Next, it provides an in-depth look into how identity became shaped prior to the Euro-American influence through an ethnographic reconstruction. These are framed in a way to form relevant hypotheses to study the regional prehistoric archaeological record. The Historical Linguistics analytical approach used here confirms that there is very little, if any, evidence in the languages …

Effects Of Sea Ice Seasonal Evolution And Oil Properties On Crude Oil Upward Migration Through Sea Ice, Marc Oggier Dec 2020

Effects Of Sea Ice Seasonal Evolution And Oil Properties On Crude Oil Upward Migration Through Sea Ice, Marc Oggier

Geosciences

Sea ice plays an essential role in polar ecosystems as a habitat for organisms at the base of the food web. Receding Arctic perennial sea ice, potential oil and gas reserves, and increasing industrial activities in the Arctic are likely to increase oil extraction and transport in the maritime Arctic. Despite a decrease in summer sea ice extent, Arctic waters remain covered with sea ice for much of the year, increasing the risk of an oil spill in and under Arctic sea ice. This dissertation addresses the need for a quantitative understanding of the timing of and constraints on oil …

A Bayesian Mixed Multistate Open-Robust Design Mark-Recapture Model To Estimate Heterogeneity In Transition Rates In An Imperfectly Detected System, Janelle J. Badger Dec 2020

A Bayesian Mixed Multistate Open-Robust Design Mark-Recapture Model To Estimate Heterogeneity In Transition Rates In An Imperfectly Detected System, Janelle J. Badger

Mathematics and Statistics

Multistate mark-recapture models have long been used to assess ecological and demographic parameters such as survival, phenology, and breeding rates by estimating transition rates among a series of latent or observable states. Here, we introduce a Bayesian mixed multistate open robust design mark recapture model (MSORD), with random intercepts and slopes to explore individual heterogeneity in transition rates and individual responses to covariates. We fit this model to simulated data sets to test whether the model could accurately and precisely estimate five parameters, set to known values a priori, under varying sampling schemes. To assess the behavior of the model …

The Reproductive Biology Of Yelloweye Rockfish (Sebastes Ruberrimus) In Prince William Sound And The Northern Gulf Of Alaska, Donald E. Arthur Dec 2020

The Reproductive Biology Of Yelloweye Rockfish (Sebastes Ruberrimus) In Prince William Sound And The Northern Gulf Of Alaska, Donald E. Arthur

Fisheries

Over the last half century, Yelloweye Rockfish Sebastes ruberrimus have experienced dramatic declines along the West Coast of the United States and British Columbia. Efforts have been made throughout the species' range to rebuild and sustainably manage stocks, including the introduction of a Statewide Rockfish Initiative by the State of Alaska, which intends to develop management strategies for Yelloweye Rockfish in the Gulf of Alaska. To support this effort and address information gaps in Yelloweye Rockfish reproductive biology throughout their range, I estimated important reproductive parameters and life history information for Yelloweye Rockfish in Prince William Sound and the Northern …

Spawning Migration Characteristics And Ecology Of Eulachon (Thaleichthys Pacificus), Robert E. Spangler Dec 2020

Spawning Migration Characteristics And Ecology Of Eulachon (Thaleichthys Pacificus), Robert E. Spangler

Fisheries

Eulachon Thaleichthys pacificus has experienced dramatic reductions in their distribution and abundance along the west coast of North America. This prompted the listing of this species as "Threatened" under the U.S. Endangered Species Act (ESA) of 1973 for populations found in the southern portions of their range, but not in Alaska. Key gaps in knowledge of Eulachon spawning ecology exist that impede population monitoring efforts and habitat protection. Currently, many monitoring efforts ignore estuaries as possible spawning habitat leading to inaccurate estimates of population abundance and trends. Furthermore, estuaries are not designated as critical spawning habitat for Eulachon. This is …

Sea Otter Diet Composition With Respect To Recolonization, Life History, And Season In Southern Southeast Alaska, Nicole Laroche Dec 2020

Sea Otter Diet Composition With Respect To Recolonization, Life History, And Season In Southern Southeast Alaska, Nicole Laroche

Fisheries

Until translocation efforts in the 1960s, sea otters (Enhydra lutris) were absent from Southeast Alaska due to extirpation by the fur trade in the 18th and 19th centuries. About 400 sea otters were reintroduced to six Southeast Alaska locations, including two sites near Prince of Wales Island in southern Southeast Alaska. The most recent US Fish and Wildlife Service population count, completed in 2012, estimated that about 25,000 sea otters inhabited Southeast Alaska. Sea otters will reduce invertebrate prey biomass when recolonizing an area. By quantifying sea otter diets and caloric intake according to recolonization patterns, we can better understand …

Reproduction And Stress Response Endocrinology In Blue (Balaenoptera Musculus) And Gray (Eschrichtius Robustus) Whales, Valentina Melica Dec 2020

Reproduction And Stress Response Endocrinology In Blue (Balaenoptera Musculus) And Gray (Eschrichtius Robustus) Whales, Valentina Melica

Fisheries

Identification of biomarkers that reflect physiological status is fundamental for assessing population health, as well as providing more accurate estimates of life history parameters. Blue (Balaenoptera musculus) and gray (Eschrichtius robustus) whale populations feed on lower trophic levels and migrate between the eastern Tropical and the eastern North Pacific Ocean. With increasing disturbances (e.g., changing environment and human activities), understanding the stress response, resultant coping mechanisms, and the subsequent effects on reproduction, is of growing importance. While extensive knowledge is available on photo-identification and ecology of these two species, information on physiology is limited and what exists is outdated. This …

Tracing Carbon Sources Of Southern Beaufort Sea And Chukchi Sea Polar Bears Using Stable Isotope Analyses, Malia E.K. Smith Dec 2020

Tracing Carbon Sources Of Southern Beaufort Sea And Chukchi Sea Polar Bears Using Stable Isotope Analyses, Malia E.K. Smith

Marine Biology

The Southern Beaufort Sea (SBS) polar bear (Ursus maritimus) subpopulation has declined in response to sea ice loss, while the Chukchi Sea (CS) subpopulation appears stable. The substantial population decline in the SBS subpopulation in recent years is concurrent with increases in the proportion of polar bears coming on shore, and the duration they spend there. Both of these changes have been associated with the loss of access to their primary sea ice habitat, which is mainly used as a platform to hunt seals. The first objective of this study was to determine if the SBS and CS polar bear …

Department of Orthopaedic Surgery Faculty Papers

There are currently no pharmacological approaches in fracture healing designed to therapeutically stimulate endochondral ossification. In this study, we test nerve growth factor (NGF) as an understudied therapeutic for fracture repair. We first characterized endogenous expression of Ngf and its receptor tropomyosin receptor kinase A (TrkA) during tibial fracture repair, finding that they peak during the cartilaginous phase. We then tested two injection regimens and found that local β-NGF injections during the endochondral/cartilaginous phase promoted osteogenic marker expression. Gene expression data from β-NGF stimulated cartilage callus explants show a promotion in markers associated with endochondral ossification such as Ihh, Alpl, …

Motivations, Environmental Attitudes, And Personal Efficacy Of Volunteers At Communitree Tree-Planting Events In Northwest Indiana, U.S., Kaitlyn Pike, Rebecca Brokaw, Jess Vogt Dec 2020

Motivations, Environmental Attitudes, And Personal Efficacy Of Volunteers At Communitree Tree-Planting Events In Northwest Indiana, U.S., Kaitlyn Pike, Rebecca Brokaw, Jess Vogt

Cities and the Environment (CATE)

In this paper, we examine the mechanisms of volunteering at tree-planting events conducted as part of a new, multi-organizational tree-planting effort in northwest Indiana called CommuniTree. A broad literature exists on general volunteerism as well as environmental volunteering, urban forestry volunteering, and even tree-planting volunteering. Yet, the motivations, environmental attitudes, and personal efficacy of urban forestry volunteers in particular are not fully understood, nor are the outcomes and implications of volunteer participation in neighborhood greening programs. A 22-question (34 individual items), self-report survey was administered in-person at CommuniTree tree-planting events in 2017 through 2019, obtaining 114 responses. CommuniTree volunteers who …

Efficient Alternative Food Systems For Earth And Space, Kyle A. Alvarado Dec 2020

Efficient Alternative Food Systems For Earth And Space, Kyle A. Alvarado

Engineering

Alternative foods are a source of human-edible calories derived from an unconventional source or process. This thesis includes two alternative foods: (i) crops grown under low-tech greenhouses in low sunlight environments and (ii) hydrogen-oxidizing bacteria (HOB) in space and Earth refuges, such as to repopulate the Earth. The purpose of alternative foods is to ensure food security for human survival. During a global catastrophic risk (GCR) scenario, such as nuclear winter or super volcanic eruption, the sun may be obscured, causing lack of crop production and therefore global food shortages. The purpose of this thesis was to improve the cost …

The Effects Of Individual And Environmental Heterogeneity On Long-Term Population Dynamics Of Cassin's Auklets (Ptychoramphus Aleuticus), Michael E. Johns Dec 2020

The Effects Of Individual And Environmental Heterogeneity On Long-Term Population Dynamics Of Cassin's Auklets (Ptychoramphus Aleuticus), Michael E. Johns

Biological Sciences

Reproductive output and survival are expected to be balanced through a tradeoff between current success and future potential, in response to environmental conditions that vary on spatial and temporal scales. Long-term datasets that follow uniquely marked animals through time are excellent tools for describing how heritable or derived traits that influence reproduction and survival can be attributed to individual quality, and how the added reproductive performance of these individuals influence population dynamics. A 37-year record of breeding histories from known-aged Cassin's auklets from Southeast Farallon Island, a colony off the coast of central California, was used to examine these ideas …

An Interdisciplinary Analysis Of Health Equity As Evaluated Through The Covid-19 Response Concerning French-Speaking Refugees., Margaret Henning

Honors Theses

A collaborative approach is needed to understand the multifaceted medical bias and inequalities experienced by refugee camps of Francophone (French-speaking) nations. A combination of interest and passion for anthropology, medicine, and the French language presents a unique window of intersectionality to analyze this issue. Through a comprehensive review of literature published in both English and French languages, and connections with directors and leaders of refugee camps located in France and French-speaking African nations, we have elucidated a few examples of alarming medical bias experienced by both refugees and migrants. Although an exhaustive list of medical bias could be presented on …
