Britain And The Anglo-Saxons In Late Antiquity, Todd Morrison

History ETDs

This thesis concerns the final century of Roman Britain, the continental origins of its medieval Germanic invaders, and the socio-political situation in sub-Roman Britain in the fifth and sixth centuries. Multiple issues are discussed in each of these three broad areas, including the effects of the Diocletian Reforms on Britain, fourth-century urban decay, the first-century origins of the Saxons among the piratical Chauci tribe, and the continued existence of Roman institutions in Britain into the early Middle Ages. Furthermore, the reasons the Anglo-Saxons did not assimilate into Roman culture like their counterparts on the continent, making medieval England an essentially …

Moose Abundance Estimation Using Finite Population Block Kriging On Togiak National Wildlife Refuge, Alaska, Graham G. Frye

Mathematics and Statistics

Monitoring the size and demographic characteristics of animal populations is fundamental to the fields of wildlife ecology and wildlife management. A diverse suite of population monitoring methods have been developed and employed during the past century, but challenges in obtaining rigorous population estimates remain. I used simulation to address survey design issues for monitoring a moose population at Togiak National Wildlife Refuge in southwestern Alaska using finite population block kriging. In the first chapter, I compared the bias in the Geospatial Population Estimator (GSPE; which uses finite population block kriging to estimate animal abundance) between two survey unit configurations. After …

Landscape-Scale Establishment And Population Spread Of Yellow-Cedar (Callitropsis Nootkatensis) At A Leading Northern Range Edge, John P. Krapek

Natural Resources

Yellow-cedar is a long-lived conifer of the North Pacific Coastal Temperate Rainforest region that is thought to be undergoing a continued natural range expansion in southeast Alaska. Yellow-cedar is locally rare in northeastern portions of the Alexander Archipelago, and the fairly homogenous climate and forest conditions across the region suggest that yellow-cedar's rarity could be due to its local migrational history rather than constraints on its growth. Yellow-cedar trees in northern range edge locations appear to be healthy, with few dead trees; additionally, yellow-cedar tend to be younger than co-dominant mountain and western hemlock trees, indicating recent establishment in existing …

Sagavanirktok River Spring Breakup Observations 2016, H. Toniolo, K.D. Tape, T. Tschetter, J.W. Homan, E.K. Youcha, D. Vas, R.E. Gieck, J. Keech, G. Upton

WERC Project Reports

In 2015, spring breakup on the Sagavanirktok River near Deadhorse was characterized by high flows that destroyed extensive sections of the Dalton Highway, closing the road for nearly 3 weeks. This unprecedented flood also damaged infrastructure that supports the trans-Alaska pipeline, though the pipeline itself was not damaged. The Alaska Department of Transportation and Public Facilities (ADOT&PF) and the Alyeska Pipeline Service Company made emergency repairs to their respective infrastructure. In December 2015, aufeis accumulation was observed by ADOT&PF personnel. In January 2016, a research team with the University of Alaska Fairbanks began monitoring and researching the aufeis and local …

An Ionization Chamber For High Resolution Fission Product Spectroscopy, James Cole

Nuclear Engineering ETDs

The fission process has played a vital role in the world’s search for effective sources of alternative energy. With almost 80 years of work with fissionable material there is still much that is unknown about the process. Fission fragment mass and atomic number distributions are still lacking in completeness and critical detail. Knowledge of this information is highly sought after in the effort to improve various fields of nuclear physics and engineering such as reactor design, predictive models, waste disposal methods, and an overall understanding of the fission process. In an effort to better understand this process, we have developed …

Bonding Theatre And Chemistry: An Educational Exploration, Matthew Gurniak

Senior Honors Projects, 2010-2019

This paper analyzes the educational aspects of theatre and music and the impact that they have on an audience. The goal was to begin a new conversation about science and theatre and how the two can learn and gain unique insight from each other. To examine how these two antithetical fields can interact, I composed a new, innovative musical that tells the love story between two professors through the use of concepts from general chemistry. The results and responses from the performance of the play were overwhelmingly positive from members of both disciplines. They have inspired continued interest in this …

A Visual Velocity Impedance Controller, Victor Nevarez

Mechanical Engineering ETDs

Successful object insertion systems allow the object to translate and rotate to accommodate contact forces. Compliant controllers are used in robotics to provide this accommodation. The impedance compliant controller is one of the more researched and well known compliant controllers used for assembly. The velocity filtered visual impedance controller is introduced as a compliant controller to improve upon the impedance controller. The velocity filtered impedance controller introduces a filter of the velocity impedance and a gain from the stiffness. The velocity impedance controller was found to be more stable over larger ranges of stiffness values than the position based impedance …

Exploring The Experience Of Foster Parents As They Care For Children Who Are Making The Transition From The Hospital Into The Foster Home, Maximilian Veltman

Nursing ETDs

This study explored the perceptions foster parents have about their work as caregivers of foster children who are hospitalized and then discharged from the hospital into a foster home. The numbers of children in foster care nationwide has decreased over the past 25 years, yet the proportion of children in foster care who have significant health conditions has increased dramatically (Wang, Edelstein, Waldinger, Lee & Bath, 2011). There has also been significant attrition of qualified foster parents who are able to care for foster children with significant health needs (Pecora, Whittaker, Maluccio, Barth & DePanfilis, 2009; Vig, Chinitz & Shulman, …

Breeding Ecology Of Whimbrels (Numenius Phaeopus) In Interior Alaska, Christopher M. Harwood

Biological Sciences

Whimbrels Numenius phaeopus breed in tundra-like habitats, both beyond treeline and within the boreal forest of interior Alaska. Despite their widespread distribution and designation as a species of conservation concern, their ecology has been particularly understudied in Alaska. During 2008--2012, I initiated the first dedicated study of Whimbrel breeding ecology in Alaska, and the first such study of any boreal-breeding shorebird in the state. Within a habitat mosaic of forest, woodlands, muskeg, scrub, and ponds within the floodplain of the Kanuti River in north-central Alaska, Whimbrels bred in the three largest (of nine) patches of discontinuous tussock tundra. These Whimbrels …

Black Phase is a speculative fiction novel for a young adult audience, set in and around a fictional boarding school in modern-day southeast Alaska. Our protagonist is Mara Edenshaw, an ambitious young artist of Tlingit descent who survives a mysterious illness only to find herself the primary suspect in a string of bizarre vandalisms. Her search to clear her name leads her to Alvis Norling, a shy alchemist’s apprentice living on a nearby island with only his own creation for company: a doll-sized homunculus made from a combination his and Mara’s DNA. Thus Mara’s illness and the vandalisms proved to …

Launch Environment Data Logger Design And Implementation For Cubesats, Morgan Johnson

Engineering

Designing to the CubeSat standard has allowed many universities the ability to launch satellites missions to space. These small satellites are secondary, or even tertiary, payloads on launch vehicles. In fact, these ride-share payloads are frequently used as ballast for weight and balance of the launch vehicle and are often mounted near the engines. The environment experienced by these CubeSats is not well known. The Launch Environment Data Logger was designed to measure temperature and vibrations of the launch vehicle to better understand what kind of environment these small satellites must survive on their ride to space. Through this thesis …

Cultural Superstitions And Residential Real Estate Prices: Transaction-Level Evidence From The Us Housing Market, Brad R. Humphreys, Adam D. Nowak, Yang Zhou

Economics Faculty Working Papers Series

In Chinese culture, the number 8 is considered lucky and 4 is considered unlucky. We analyze the relationship between the presence of 8 s and 4 s in addresses and transaction prices paid by Chinese home buyers and sellers in a novel setting, Seattle, Washington, from 1990 to 2015. In the absence of explicit identifiers for Chinese individuals, we develop a probabilistic model for identifying ethnicity based on name alone. The results indicate Chinese buyers pay a 1-2% premium for addresses that include an 8 and 1% less for properties with a 4 in the address. These results are not …

Evaluation Of Growth, Survival, And Recruitment Of Chinook Salmon In Southeast Alaska Rivers, Cory J. Graham

Fisheries

Recent reductions in the run sizes of Chinook Salmon Oncorhynchus tshawytscha in Southeast Alaska have resulted in social and economic hardships within the region. Pacific salmon yearclass strength may be determined by size-selective processes during the early marine phase of their life cycle; however, the relative importance of growth during freshwater and marine residence in determining recruitment success is unknown. A scale-based retrospective analysis was conducted to examine the effects of freshwater and annual marine growth and early marine conditions on survival to reproductive maturity for female Chinook Salmon by brood year (BY) in the Taku (BYs 1979 -- 1985, …

Compositional Characteristics And Ages Of Plutons In The Central Ruby Batholith, Alaska: Implications For Rare-Earth-Element Resources, Amy L. Tuzzolino

Geosciences

The central Ruby batholith, comprising much of the Ray Mountains in central Alaska, consists of at least ten, largely monzogranitic plutons, some of which have been defined as a result of this thesis. The general age of the batholith is estimated at 111 Ma, yet recent ⁴⁰Ar/³⁹Ar muscovite and ²³⁸U/²⁰⁶Pb zircon data suggests greater variability in ages than previously known, with ages now spanning 90 to 112 Ma. Initial ⁸⁷Sr/⁸⁶Sr ratios for the area show a general increase from northeast (minimum of 0.706) to southwest (maximum of 0.727). There are two characteristic mineral assemblages distinguishing the plutons: The northern plutons …

IMPROVING QUALITY AND EFFICIENT COMMUNICATION BETWEEN

PROVIDERS AND NURSING - A PSYCHIATRIC SBAR TOOL (PSYCH)

Karen Richards

University of San Francisco

Abstract

Effective communication is the cornerstone of providing safety and quality healthcare. However, nursing and providers often share information inequitably, as these disciplines are trained differently regarding communication. Providers are taught to be brief, accurate and focused while nurses are taught to be descriptive and holistic. These differences have led to disparity in the sharing of valuable patient information, subsequently leading to increased frustration, inefficiency, and medical errors. Multiple studies provide evidence that poor communication is a major contributor …

On Frequency Variation Of Dynamic Resting-State Functional Brain Network Activation And Connectivity With Applications To Both Healthy And Clinical Populations, Maziar Yaesoubi

Electrical and Computer Engineering ETDs

One of the earliest and fundamental observation in scientific study of the brain was discovering the relation between activities in different local regions of brain and some core functions of the brain. This was later followed by observing that not only local activities of regions but also synchronous activities between distributed brain regions play a key role in high-level brain functions. Synchronous activity related to the functions of the brain is commonly referred to as functional connectivity (FC) and is studied in the form of connectivity states of the brain which measure degree of interactions between distributed parts of the …

The Acidic Sulfonimidation Of Aryl–Oxazolines And The Electrophilic Fluorination Of Aryl–Oxazolines, David Gutierrez

Master's Theses

Aryl oxazolines have been employed as directing groups for several different coupling reactions. In the exploration of using phenyl oxazoline as a directing group for electrophilic fluorination, it was discovered that acidic sulfonimide nucleophiles including dibenzenesulfonimide, o–benzenesulfonimide, dimethanesulfonimide, and N–(methylsulfonyl)–benzenesulfonamide are discovered to open a variety of alkyl, aryl and heteroaryl–2–oxazoline rings to provide the sulfonimidation products in refluxing 1,4–dioxane. The electron rich 2–oxazoline substrates worked well for the nucleophilic ring opening reactions while no reaction took place for the electron poor 2–oxazoline substrates. 4,4–dimethyl–2–phenyl–2–oxazoline was thus rationally designed inhibit sulfonimidation and to act as a removable ortho directing group …

Cloning And Expression Of Bovine Alpha S1 Casein Peptides Of Variable Size And Position Of Sppep Inhibitor Sequence, Avleen Kaur Vishram

Electronic Theses and Dissertations

Eurygaster integriceps Puton (Sunn pest) is the most damaging insect pest of wheat in areas of North Africa, Eastern Europe and Western and Central Asia. Sunn pest injects an enzyme characterized as a prolyl endylprotease (spPEP) into wheat grains that digests the gluten protein (Darkoh et al., 2010). Previous studies have shown that casein peptides generated by Lactobacillus species have inhibitory effects on human (hPEP) and bacterial prolyl endoproteases (bPEP) which makes casein a good natural candidate to inhibit spPEP. Developing biopesticides for food products from αS1 casein is complicated due to some allergenic amino acid sequences. Ruiter et al …

Unmanned Aircraft System Assessments Of Landslide Safety For Transportation Corridors, Keith Cunningham, Michael J. Olsen, Matt O'Banion, Joseph Wartman, Claire Rault

INE Project Reports

An assessment of unmanned aircraft systems (UAS) concluded that current, off-the-shelf UAS aircraft and cameras can be effective for creating the digital surface models used to evaluate rock-slope stability and landslide risk along transportation corridors. The imagery collected with UAS can be processed using a photogrammetry technique called Structure-from-Motion (SfM) which generates a point cloud and surface model, similar to terrestrial laser scanning (TLS). We treated the TLS data as our control, or “truth,” because it is a mature and well-proven technology. The comparisons of the TLS surfaces and the SFM surfaces were impressive – if not comparable is many …

A Scuba-2 Survey Of Felobal Qsos. Are Felobals In A ‘Transition Phase’ Between Ulirgs And Qsos?, Giulio Violino, Kristen E. K. Coppin, Jason A. Stevens, Duncan Farrah, James E. Geach, Dave M. Alexander, Ryan Hickox

Dartmouth Scholarship

It is thought that a class of broad absorption line (BAL) QSOs, characterised by Fe absorption features in their UV spectra (called `FeLoBALs'), could mark a transition stage between the end of an obscured starburst event and a youthful QSO beginning to shed its dust cocoon, where Fe has been injected into the interstellar medium by the starburst. To test this hypothesis we have undertaken deep SCUBA-2 850 μm observations of a sample of 17 FeLoBAL QSOs with 0.89 ≤ z ≤ 2.78 and -23.31 ≤ MB ≤-28.50 to directly detect an excess in the thermal emission of the dust …

Speed-Ups And Slowdowns: Insights Into Velocity Variations Measured From 2009-2011 On Yahtse Glacier, Alaska, Jessica Zimmerman Mejia

Geosciences

Water at the bed of a glacier can alter the basal stress distribution that governs basal motion and is responsible for short-term velocity variations. Accelerated basal motion has lead to increased ice discharge on tidewater glaciers, influencing the glacial contribution to sea level rise. The development of a temporally high-resolution model requires understanding the dynamic elements of the subglacial drainage system that govern short-term velocity variations. Here, we use global positioning system (GPS) observations to document the relationship between basal motion and widely variable water inputs on Yahtse Glacier over three years. Yahtse Glacier is a temperate, grounded, tidewater glacier …

Current State Of Alaska's Glaciers And Evolution Of Black Rapids Glacier Constrained By Observations And Modeling, Christian Kienholz

Geosciences

Glaciological studies rely on a wide range of input data, the most basic of which, accurate glacier extents, were not available on an Alaska wide scale prior to this work. We thus compiled a glacier database for Alaska and neighboring Canada using multi-sensor satellite data from 2000 to 2011. The inventory yielded a glacierized area of 86,720 km², which corresponds to ~12% of the global glacierized area outside the ice sheets. For each of the ~27,100 glaciers, we derived outlines and 51 variables, including centerline lengths, outline types, and debris cover, which provide key input for observational and modeling studies …

Estimation Of Full Moment Tensors, Including Uncertainties, For Earthquakes, Volcanic Events, And Nuclear Explosions, Celso R. Alvizuri

Geosciences

We present a catalog of full seismic moment tensors for 63 events from Uturuncu volcano in Bolivia. The events were recorded during 2011-2012 in the PLUTONS seismic array of 24 broadband stations. Most events had magnitudes between 0.5 and 2.0 and did not generate discernible surface waves; the largest event was Mw 2.8. For each event we computed the misfit between observed and synthetic waveforms, and we used first-motion polarity measurements to reduce the number of possible solutions. Each moment tensor solution was obtained using a grid search over the six-dimensional space of moment tensors. For each event we show …
