Pickering Lumber Company: Archival Processing Project, Joyce Madeline Pitts

Electronic Theses and Dissertations

Founded by W.R. Pickering in 1894, the Pickering Lumber Company had lumber operations in Oklahoma, Texas, Louisiana, and California. The company practiced cut-and-run policy that dictated the relocation of lumber operations when the company exhausted its timber holdings. The Pickering Lumber Company operated in Texas and Western Louisiana from 1898 to roughly 1930 when timber holdings were exhausted and financial difficulties brought on by the Great Depression required the withdrawal of the company from its mill at Haslam. This thesis narrates the story of the Pickering Lumber Company and explains the procedures undertaken to process the Pickering Lumber Company Collection …

Opening, Renee M. Wilcox

Electronic Theses and Dissertations

While examining some of the dark, chaotic, destructive issues that exist on a global level, I see an opposite movement actively emerging as a means to counteract, mend, and create new patterns of non-violent communication. This change is an opening to new beginnings. Opening expresses this concept through iconography, the use of symbols, which opens an internal and external dialog with the viewer, through incorporating text, and through portraits of contemporary leaders who are devoted to peace-building work. Members of the community have also expressed this desire to open themselves up to these possibilities, through their written intentions and dreams, …

Risky health behaviors including substance abuse and risky sex are a significant contributor to chronic illness in the US. Efficient use of public resources to avert or mitigate the consequences of risky health behaviors requires a better understanding of the overall costs of risky health behavior to society. Additionally, a better understanding of the value and behavioral consequences of programs designed to mitigate the consequences of risky health behavior is needed. This dissertation utilizes a number of unique methodological and empirical tools to examine the consequences of risky sex and drug abuse and the value of policies which seek to …

African Dreams Of America: Diaspora Experience In The Writing Of Aidoo, Adichie And Cole, Gbenga Frederick Olorunsiwa

American Studies ETDs

This study explores four African diasporic texts against a backdrop of the African dream of America, diasporic experience, post-colonialism and racism in the U.S. as portrayed in the writings of Ama Ata Aidoo’s The Dilemma of a Ghost (1971), Chimamanda Adichie’s Americanah (2014), and Teju Cole’s Open City (2012) and Every Day Is for the Thief (2014). I argue that the African dream of America is different but also exemplary of the American experience and therefore a privileged lens for understanding “America.” During the course of this research project, I found that while the writings of Adichie and Aidoo are …

Mitigating The Impacts Of Human Land-Use Change On Biodiversity: With A Focus On Large Migratory Herbivores, Kina Rebekah Murphy

Biology ETDs

Land-use change, commercial over-harvesting of species, and climate change are recognized as the main drivers of biodiversity loss. As a result, it is estimated that 30% of the planet’s biodiversity may go extinct by 2050. This dissertation focuses on how to mitigate the impacts of land-use change on biodiversity. I focus on large migratory herbivores because they are among the most heavily impacted by global change due to their large home range requirements. Habitat fragmentation, illegal hunting, and human-wildlife conflicts are among the biggest threats to large herbivores and result from land-use change. For this reason, my first chapter focuses …

Impacts Of Long-Term Precipitation Manipulation On Hydraulic Architecture, Xylem Function, And Canopy Status In A Piñon-Juniper Woodland, Patrick J. Hudson

Biology ETDs

The Southwestern US is predicted to become hotter and drier, as global climate change forces increasing temperatures and variability in timing and size of precipitation inputs. Drought stress has become more frequent in recent decades, and resulted in massive forest mortality in piñon-juniper woodlands. During recent severe droughts (2000-2003, 2009-2012), piñon pine (Pinus edulis Englem.) suffered disproportionately high mortality compared to co-occurring one-seed juniper (Juniperus monosperma [Engelm.] Sarg.). A large-scale precipitation manipulation experiment was established in a piñon-juniper woodland in central New Mexico to test hypotheses regarding tree survival and mortality with respect to altered water regimes. Our …

What Affects Parents’ Choice Of Milk? An Application Of Bayesian Model Averaging, Yingzhe Cheng

Mathematics & Statistics ETDs

This study identifies the factors that influence parents’ choice of milk for their children, using data from a unique survey administered in 2013 in Hunan province, China. In this survey, we identified two brands of milk, which differ in their prices and safety claims by the producer. Data were collected on parents’ choice of milk between the two brands, demographics, attitude towards food safety and behaviors related to food. Stepwise model selection and Bayesian model averaging (BMA) are used to search for influential factors. The two approaches consistently select the same factors suggested by an economic theoretical model, including price …

Factors Influencing The Timing And Frequency Of Moose-Vehicle Collisions At Urban-Wildland Interfaces In Subarctic Alaska, Jacobus Cornelis Noordeloos

Natural Resources

Wildlife-vehicle collisions concern road engineers, wildlife biologists, and the motoring public. In Alaska, moose-vehicle collisions (MVCs) are the most commonly reported type of wildlife-vehicle collisions. Each year an average of 101 MVCs were reported in the Fairbanks North Star Borough (FNSB), resulting in damages amounting to $3,000,000/yr. This thesis describes the spatial and temporal patterns of MVCs in the FNSB and uses these patterns to infer the interactions between human and moose behavior that cause them. The analytical approach used combined spatial and temporal records of MVCs collected by the Alaska Department of Transportation with spatially explicit data describing topography, …

Book Clubs In The Esl Classroom: A Microinteractional Analysis Of Literacy Development In Adult Esl Students, Sharon E. Johnson

English

This study uses conversation analysis to identify literacy development in adult ESL classroom book club discussions. The investigation focuses on the interactions of three university students participating in a six-week book club about Harry Potter and the Sorcerer's Stone. The longitudinal microethnographic analysis reveals the students' development of interactional routines for enacting topic transitions. Two student strategies are examined: (a) the development of a group routine for reading discussion questions aloud; and (b) the use of the transition markers okay and next. The students' establishment of these strategies during the six meetings provides evidence of literacy development during classroom book …

Applying A Model Of Orographic Precipitation To Improve Mass Balance Modeling Of The Juneau Icefield, Aurora Roth

Geosciences

Mass loss from glaciers in Southeast Alaska is expected to alter downstream environmental conditions such as streamflow patterns, riverine and coastal ecological systems, and ocean properties. To investigate these potential changes under future climate scenarios, accurate climate data are needed to drive glacier mass balance models. However, assessing and modeling precipitation in mountainous regions remains a major challenge in glacier mass balance modeling. We have used a linear theory of orographic precipitation model (LT model) to downscale precipitation from both the Weather Research and Forecasting (WRF) model and the European Centre for Medium-RangeWeather Forecasts interim reanalysis (ERA-Interim) to the Juneau …

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 …

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 …

Fractured Reservoir Potential And Tectonic Development Of The Iniskin -- Tuxedni Region, Lower Cook Inlet, Alaska, Jacob L. Rosenthal

Geosciences

Fracture patterns can provide insight into the strain history and stress evolution of deformed strata. In southern Alaska's Cook Inlet forearc basin, hydrocarbon traps are typically fault-cored anticlines, where fractures likely aid in the migration of hydrocarbons from lower Jurassic marine strata into Cenozoic non-marine deposits. Consequently, understanding the distribution and orientation of fracture sets with respect to these structures is necessary to improving the understanding of one of Alaska's largest petroleum provinces. Furthermore, recent refinements in understanding southern Alaska's Dynamic Cenozoic tectonic evolution allow us to interpret fractures in a regional tectonic context. Despite the important role fractures likely …

Speciation, Transport And Mobility Of Metals In Pristine Watersheds And Contaminated Soil Systems In Alaska, Amanda J. Barker

Chemistry and Biochemistry

The fate of metal(loid)s in the environment depends on a variety of physical and geochemical factors. Assessing metal(loid) transport in soil solution and surface water requires detailed knowledge of the speciation, which can often control mobility, toxicity and bioavailability of a given element. The present study details the geochemical analyses of two end member types of systems: a 'pristine' Arctic watershed and a military shooting range with an overall focus on understanding lead (Pb) and antimony (Sb) mobility in shooting range soils. The project uses bulk speciation analyses coupled with micro-scale methods to quantify variations in metal(loid) concentration as a …

Mechanisms Of Modulation Of Nicotinic Acetylcholine Receptors, Arianna L. Demmerly

Chemistry and Biochemistry

Inappropriate expression of nicotinic acetylcholine receptors in the central nervous system is associated with nicotine addiction, Alzheimer's disease, Parkinson's disease and other disorders. Modulators (drugs) have the potential to restore circuit properties that arise from inappropriate expression of nicotinic receptor's. Compounds that interact with allosteric sites have a distinct advantage over agonists and partial agonists, in that, they retain normal activation patterns by allowing binding of the endogenous ligand. Positive allosteric modulators boost the receptors ability to respond to agonist. Studies of these modulators constitute a first step toward the identification and development of better compounds that minimize signaling errors …

A New Affordability Indicator For Rural Alaskan Water Utilities, Barbara A. Johnson

Economics

The Alaska Department of Environmental Conservation (DEC) administers funding for the construction of new water utilities in rural parts of the state. Funding allocation is partially based on whether the recipient community can cover the annual operation, maintenance, repair, equipment and capital replacement costs of the utility. Currently, the DEC deems a project affordable if the annual costs account for 5% or less of the community's median household income (MHI). In rural Alaska MHI is an inaccurate affordability indicator. This is partially because MHI fails to reflect the cost burden experienced by below median income households, it is a static …

Using Superdarn To Predict Polar Irregularities That Cause Gps Scintillation, Michelle R. Simon

Engineering

High levels of scintillation caused by strong magnetic storms can cause GPS devices to lose connection with the necessary satellites. Current research has shown a correlation between major magnetic storms and higher levels of the recorded Total Electron Content (TEC) seen in GPS receivers. The research presented in this thesis examines the idea that observations from the Super Dual Auroral Radar Network (SuperDARN) can be used to predict scintillation levels in GPS receivers at polar latitudes by using GPS scintillation values σφ and S4 that were collected from January, 2013 till November, 2015. These values were gathered from Poker Flat, …

Analysis Of Unfrozen Water In Cation-Treated, Fine-Grained Soils Using The Pulse Nuclear Magnetic Resonance (P-Nmr) Method, Aaron M. Kruse

Engineering

Unfrozen water within frozen soils is a key component that determines a soil's thermophysical response to changing physical and environmental conditions. This research focuses on the use of pulse nuclear magnetic resonance (P-NMR) for measuring unfrozen water content within frozen soils. The research is divided into two components: 1) improvements made to the P-NMR testing method, including refinements in the laboratory set up and testing procedure, and experimental validation of the normalization method; and 2) determination of unfrozen water content of fine-grained, cation-treated samples at various sub-freezing temperatures using the improved P-NMR methodology. Previous P-NMR testing used the first return …

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 …

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 …

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 …
