Effects Of Target Properties On The Formation Of Lunar Impact Craters In The Simple-To-Complex Transition, Mitali Chandnani

Geosciences

The transition from simple to complex crater morphology in impact craters with increase in crater size has been modelled and observed in planetary bodies across the Solar System. The transition diameter depends upon the strength and gravity of the planetary body. On the Moon, this transition takes place over a diameter range of several kilometers. This range spans a diversity of crater morphologies including simple, transitional and complex craters. The diameter range of 15 20 km falls within the lunar simple-to-complex transition. All other impactor properties held constant, the 15-20 km range corresponds to a factor of three in the …

The Role Of Tundra Vegetation In The Arctic Water Cycle, Jason A. Clark

Engineering

Vegetation plays many roles in Arctic ecosystems, and the role of vegetation in linking the terrestrial system to the atmosphere through evapotranspiration is likely important. Through the acquisition and use of water, vegetation cycles water back to the atmosphere and modifies the local environment. Evapotranspiration is the collective term used to describe the transfer of water from vascular plants (transpiration) and non-vascular plants and surfaces (evaporation) to the atmosphere. Evapotranspiration is known to return large portions of the annual precipitation back to the atmosphere, and it is thus a major component of the terrestrial Arctic hydrologic budget. However, the relative …

Prudhoe Bay West End Gas Lift Supply Optimization, Irwin Chou

Engineering

The western extension of Alaska's Prudhoe Bay, known collectively as Eileen West End (EWE), operates under a gas lift pressure supply constraint. This constraint is largely contributed by two factors: the extensively long gas lift supply line that stretches across the western field and the large number of production wells offtaking gas lift to stay online or enhance production. The gas lift supply line is approximately 18.5 miles long and provides gas lift to 200+ production wells. This results in a pressure drop severe enough to start hindering production on the western most side of the field as low gas …

To Freeze Or Not To Freeze: That Is The Question: A Look At Freezeback Landfills And Final Cover Designs, Sarah Durand

Engineering

Freezeback landfills are an exciting concept but challenging in execution. There is not a single variable that leads to the success of a freezeback landfills but multiple variables in balance with each other that allow for freezeback to occur. Freezeback landfills should be engineered to the site-specific environment at the initial design stage for a better chance of success rather than following the generalized regulatory requirements. This project looked at three freezeback landfills as case studies and evaluated the final cover design of the first two in identifying parameters that lead to success in reaching and maintaining freezeback status. The …

Multistate Ornstein-Uhlenbeck Space Use Model Reveals Sex-Specific Partitioning Of The Energy Landscape In A Soaring Bird, Joseph M. Eisaguirre

Mathematics and Statistics

Understanding animals’ home range dynamics is a frequent motivating question in movement ecology. Descriptive techniques are often applied, but these methods lack predictive ability and cannot capture effects of dynamic environmental patterns, such as weather and features of the energy landscape. Here, we develop a practical approach for statistical inference into the behavioral mechanisms underlying how habitat and the energy landscape shape animal home ranges. We validated this approach by conducting a simulation study, and applied it to a sample of 12 golden eagles Aquila chrysaetos tracked with satellite telemetry. We demonstrate that readily available software can be used to …

Explorations Of Intergenerational Healing, Resilience, And Post-Traumatic Growth By Helpers And Healers On The Blackfeet Nation, Tyler J. Hoyt

Psychology

This project explored intergenerational healing, resilience, and post-traumatic growth within the context of the Blackfeet Nation in Montana, the roles of helpers and healers in this setting, and community experiences of familial trauma and the idiosyncratic healing and resilience processes according to their worldview. The central goal of this study was to provide a contemporary public narrative surrounding healing and resilience as these topics related to historical and intergenerational trauma in this specific community. This exploratory study was composed of the narratives of 14 co-participants working as helpers and healers on the Blackfeet Nation. Indigenous narrative and a cosmic relationality …

Ecological Interactions Among Important Groundfishes In The Gulf Of Alaska, Cheryl L. Barnes

Fisheries

Complex ecological interactions such as predation and competition play an important role in shaping the structure and function of marine communities. In fact, these processes can have greater impacts than those related to fishing. We assessed ecological interactions among economically important fishes in the Gulf of Alaska - a large marine ecosystem that has recently undergone considerable shifts in community composition. Specifically, we developed an index of predation for Walleye Pollock (Gadus chalcogrammus) to examine spatiotemporal changes in consumption, quantify portfolio effects, and better understand diversity-stability relationships within the demersal food web. We also evaluated the potential for competition between …

Regional Distribution, Life History, And Morphometry Of Spawning Stage Capelin Mallotus Villosus, Kirsten N. Ressel

Fisheries

Capelin Mallotus villosus is a forage fish that is integral to many Arctic and subarctic marine food webs, but is less thoroughly studied outside the Atlantic Ocean. The goal of this research was to study spawning Capelin in data-poor areas, particularly in waters off the coast of Alaska and the western Canadian Arctic, to enrich baseline data and allude to intraspecies diversity. Chapter one examined the distribution and life history of spawning Capelin in Norton Sound, Alaska, by conducting aerial surveys, collecting sediment samples to characterize beach spawning habitats, and identifying biological attributes of spawners (e.g., body size, age, fecundity, …

Foraging Tactics Of Humpback Whales Feeding Near Salmon Hatchery-Release Sites In Southeast Alaska, Madison M. Kosma

Fisheries

Increases in the humpback whale (Megaptera novaeangliae) population have generated considerable interest in understanding the foraging habits of these large marine predators in the Gulf of Alaska. Globally, humpback whales are classified as generalist predators but are known to exhibit localized differences in diet. Intensified predation pressure is of particular concern to resource managers, who have observed whales feeding at juvenile hatchery salmon release sites in Southeast Alaska. We assessed the diets and behavioral tactics of humpback whales foraging near Hidden Falls Hatchery release sites (in Chatham Strait, 2016 to 2018) to better understand their predatory effects on juvenile hatchery-reared …

Gamestop’S Next Play: Reconfiguring The Value Offering, A. Erin Bass, Erin G. Pleggenkuhle-Miles, Christopher Winchester, Thomas West

Management Faculty Publications

Theoretical basis

The theoretical basis for this case is a focus on strategic positioning as related to Porter’s generic strategies. The case describes GameStop’s previous differentiation approach, executed through physical stores and knowledgeable staff. With technological shifts and the introduction of digital downloads, this strategy is less effective. The case requires students to consider how GameStop might revise its generic strategy based on the new competitive landscape in which it operates.

Research methodology

In writing this case, the research team conducted thorough analysis through primary data collection in stores as well as secondary data collection through the use of market …

Using Nano- And Micro- Structural Materials For Concrete Environmental Applications, Hala Nabeel Elia

Theses and Dissertations

Utilized globally in the construction industry, concrete is an integral component of homes, roads, airports, skyscrapers, and tunnels. Traditional concrete components are cement, fine aggregate (sand), coarse aggregate (gravel or crushed stone), and water. When cement and water compound together they will make a paste which binds all the aggregates together to make the concrete. Unfortunately, every one ton of cement manufactured emits 0.9 ton of CO2into the air. The goal of this two-part work was to obtain an environmentally friendly concrete. The first part used supplementary cementitious materials (SCM), fly ash and silica fume, to create concrete with high …

Mutation Signature Analysis Identifies Increased Mutation Caused By Tobacco Smoke Associated Dna Adducts In Larynx Squamous Cell Carcinoma Compared With Oral Cavity And Oropharynx., Andrew P. South, Nicoline Y Den Breems, Tony Richa, Uche Nwagu, Tingting Zhan, Shiv Poojan, Ubaldo E. Martinez-Outshoorn, Jennifer M. Johnson, Adam J. Luginbuhl, Joseph Curry

Kimmel Cancer Center Papers, Presentations, and Grand Rounds

Squamous cell carcinomas of the head and neck (HNSCC) arise from mucosal keratinocytes of the upper aero-digestive tract. Despite a common cell of origin and similar driver-gene mutations which divert cell fate from differentiation to proliferation, HNSCC are considered a heterogeneous group of tumors categorized by site of origin within the aero-digestive mucosa, and the presence or absence of HPV infection. Tobacco use is a major driver of carcinogenesis in HNSCC and is a poor prognosticator that has previously been associated with poor immune cell infiltration and higher mutation numbers. Here, we study patterns of mutations in HNSCC that are …

Measuring Person–Job Fit And Career Paths Of Distance Learning Librarians, Jennifer J. Rundels, Anne Marie Casey

Publications

While person–job fit has been used to determine satisfaction in many professions, no research has been done among distance learning librarians. This study investigates person–job fit among librarians with primary distance learning responsibility compared to librarians with some distance learning responsibility and examines whether a common career path exists among the two groups. Responses indicate that librarians who work primarily in distance learning perceive a slightly better fit with their positions and the work itself while those with some distance learning responsibility experience a slightly better fit within their library organizations. Career advancement is a common motivator for both groups.

Personal Identity, Psychological Continuity, And Survival, James D. Martin, Dennis Earl

Honors Theses

In this paper, I consider the question of personal identity, namely: in virtue of what is one person the same person at two different points in time? I first raise objections to theories which argue it is in virtue of physical continuity or continuity soul, then argue that an account of psychological continuity is most successful. One might object to psychological continuity on the grounds of reduplication and fusion problems. I argue that strict numerical identity is a bar set too high and rather that survival (construed as the continuation of a first-person perspective) is what matters for personal identity. …
