The 1951 Bristol Bay Salmon Strike: Isolation, Independence And Illusion In The Last Frontier, Nicole Susan Mccullough

Arctic and Northern Studies

Many people consider Alaska the last frontier, isolated and independent from the rest of the United States. An analysis of the salmon industry in Bristol Bay and a strike that occurred in 1951 cast doubt upon this belief. The labor dispute and preceding events paint a vivid picture of a population clearly dependent on a fishing industry controlled by absentee owners who manipulated events from Seattle and San Francisco. The strikers included Natives and Non-Natives who joined together to fight the powerful cannery owners and west coast unions who sought to expand their membership. Some of these unions had suspected …

Ultraviolet Light-Emitting Diodes At 340 Nm Using Quaternary Alingan Multiple Quantum Wells, V. Adivarahan, A. Chitnis, J. P. Zhang, M. Shatalov, J. W. Yang, Grigory Simin, M. Asif Khan, R. Gaska, M. S. Shur

Faculty Publications

An ultraviolet light-emitting diode with peak emission wavelength at 340 nm is reported. The active layers of the device were comprised of quaternary AlInGaN/AlInGaN multiple quantum wells, which were deposited over sapphire substrates using a pulsed atomic-layer epitaxy process that allows precise control of the composition and thickness. A comparative study of devices over sapphire and SiC substrates was done to determine the influence of the epilayer design on the performance parameters and the role of substrate absorption.

Finite Element Analysis Of Yield Functions Of Kelvin Foams With Open Cells, Beiqing Huang

Engineering

Proper design of foams requires an understanding of the response of the materials to stress. This thesis, based on finite element analysis, provides numerical solutions in modeling the yield behavior of Kelvin foams. The FEA model, representing a complicated unit cell, was calculated and meshed. C++ programs were designed and implemented to generate meshes for unit cells. Finite element analyses were performed for many cases. Multiple methods were employed for the determination of yield points which form yield surfaces. Comparisons between several results have been made. Our FEA results, Zhang's function and Gibson's theory show good agreements except some differences …

An Economic Appraisal Of Hole Cleaning Using Hydraulic Horsepower And Jet Impact Force, James Alfred Wright

Engineering

In today's competitive business environment, reducing operating cost means dollars to the bottom line. One way that a drilling company can reduce operating cost is by optimizing energy use at the mud pumps. The mud pumps are massive pieces of equipment that are the backbone of the cutting's removal system. Optimizing the hydraulics program is one way to reduce mud pump operating cost. Big hydraulics play an important role in the drilling process. The beneficial action of the fluid's cleaning the bottom hole and the bit teeth, and carrying particles into the annulus is well-established. A variety of hydraulic optimization …

Herbivore-Mediated Effects On Ecosystem Processes In A Near-Arctic Salt Marsh, Brian Thomas Person

Biological Sciences

Herbivores influence, and often regulate energy flow. I investigated interactions between herbivory and the foods on which geese rely while nesting and rearing their broods on the Yukon-Kuskokwim Delta in southwestern Alaska. In a captive Cackling Canada gosling (Branta Canadensis minima) experiment I decoupled the effects of seasonal declines in forage quality and availability on gosling development. An 11% decline in forage quality translated to goslings that were structurally smaller and 100 g lighter at 31 days of age. Forage availability had similar effects on gosling size, and the combined magnitude of these effects are similar to those observed in …

Role Of Wetlands And Endogenous Factors On Incubation Behavior Of Nesting Spectacled Eiders On The Yukon-Kuskokwim Delta, Alaska, William Todd O'Connell

Biological Sciences

Patterns of nest attendance in ducks vary with endogenous and environmental factors. We examined variation in nest attendance of spectacled eiders on the Yukon-Kuskokwim Delta, Alaska, during 1997-1998. We also examined spatial and temporal variation in wetland characteristics and potential foods available to nesting spectacled eiders. Time spent foraging was greater when spectacled eiders traveled farther to feed, and nest attendance was lower when food was more abundant, suggesting that females made tradeoffs between foraging and energetic requirements of nesting in response to food abundance and wetland conditions. Wetlands were dynamic, and food abundance varied with pond depth and total …

Cross-Seasonal Effects On Reproductive Performance Of Pacific Black Brant, Jason Lee Schamber

Biological Sciences

We used re-sightings of Pacific Black Brant from San Quintin Bay, Ojo de Lieber Lagoon, and San Ignacio Lagoon, Baja California and Boundary Bay, British Columbia, to examine winter population structure, variation in structural size and the importance of winter location to individual reproductive performance at the Tutakoke River colony. Sexes of adults and juveniles were distributed equally among winter locations. Adult structural size and mean age were similar among winter locations. A higher proportion of juveniles over-wintered in San Quinton Bay and Ojo de Liebre Lagoon. Individuals wintering at Ojo de Liebre and San Ignacio lagoons were less likely …

Trace Mineral Reserves For Reproduction And Development In Muskoxen, Emmajean Pearl Rombach

Biological Sciences

In muskoxen (Ovibos moschatus), trace minerals required for reproduction and development are unknown. I described use of copper in pregnant muskoxen and concurrent accumulation of copper in fetuses. Utilization of copper was examined in neonates during early development and importance of milk as a source of copper was assessed. Additionally, I examined the effect of maternal copper supplementation during gestation on copper reserves acquired in-utero, and during lactation on mineral status of milk. During gestation, the fetus must acquire reserves of copper adequate to support early neonatal development because milk is a poor source of copper. The transition from milk …

Abundance And Ecology Of Martens (Martes Americana) In Interior Alaska, Brad Shults

Biological Sciences

I studied marten (Martes americana) abundance and ecology in the Yukon-Charley Rivers National Preserve during 1991-1993. Using a multiple sample, mark-recapture estimator, I estimated marten densities to be 0.69, 0.41, and 0.45 martens/km² during each August for 1991-1993, respectively. Density estimates were derived with the boundary-strip method to address the edge effect inherent in live-trapping studies. During the study, marten density declined 43% between 1991 and 1992 and remained low during 1993. I hypothesize that a decline in primary prey (i.e., microtine rodents) and increased environmental stress (i.e., cold temperatures and snow cover) contributed significantly to the decline in marten …

Visual Spatial Memory Is Enhanced In Female Rats (But Inhibited In Males) By Dietary Soy Phytoestrogens, Edwin D. Lephart, Trent D. Lund, Timothy W. West, Lilyan Y. Tian, Lihong H. Bu, Daniel L. Simmons, Kenneth Setchell, Herman Adlercreutz

Faculty Publications

In learning and memory tasks, requiring visual spatial memory (VSM), males exhibit superior performance to females (a difference attributed to the hormonal influence of estrogen). This study examined the influence of phytoestrogens (estrogen-like plant compounds) on VSM, utilizing radial arm-maze methods to examine varying aspects of memory. Additionally, brain phytoestrogen, calbindin (CALB), and cyclooxygenase-2 (COX-2) levels were determined. Results: Female rats receiving lifelong exposure to a high-phytoestrogen containing diet (Phyto-600) acquired the maze faster than females fed a phytoestrogen-free diet (Phyto-free); in males the opposite diet effect was identified. In a separate experiment, at 80 days-of-age, animals fed the Phyto-600 …

The Ecology Of Age-1 Copper Rockfish (Sebastes Caurinus) In Vegetated Habitats Of Sitka Sound, Alaska, Michael M. Byerly

Fisheries

Variables that may indicate habitat quality were measured to assess the relative value of shallow subtidal vegetated habitats to age-1 copper rockfish (Sebastes caurinus). All habitats studied appeared beneficial to fish with respect to the particular variable measured. Relative growth rate was significantly higher in kelp than in other habitats while energy content was highest in eelgrass. Though fish in eelgrass had lower growth rates, they were significantly larger, and had high densities. Mixed kelp and eelgrass habitat was suboptimal with respect to growth and energy content but also had high densities. Fish in mixed habitat moved the least both …

Diets Of Juvenile Flatfishes Near Kodiak Island, Alaska, Brenda A. Holladay

Fisheries

Flathead sole, Pacific halibut, rock sole, and yellowfin sole were found co-existing near Kodiak Island as juveniles (<200 mm) during late summer. Dietary differences were attributed to fish species, size, and depth-sediment characteristics of their habitat. Two to three size classes were assigned within each species. Across all habitats, significant differences in dietary composition, stomach fullness, and diet diversity were found between size classes of different flatfish species. Within a single depth-sediment habitat, flatfishes of different species and size classes ate similar prey. Seven of nine species size classes had similar prey composition across multiple habitats. Significant differences in dietary composition across habitats were detected only for small Pacific halibut and small rock sole. The juvenile flatfishes near Kodiak were opportunistic feeders, and appeared to select habitat based on parameters other than the presence of specific prey taxa.

Laser Intensity Scaling Through Stimulated Scattering In Optical Fibers, Timothy H. Russell

Theses and Dissertations

The influence of stimulated scattering on laser intensity in fiber optic waveguides is examined. Stimulated Brillouin scattering (SBS) in long, multimode optical waveguides is found to generate a Stokes beam that propagates in the fiber LP01 mode. Additionally, the same process is found to combine multiple laser beams into a single spatially coherent source. Limitations in beam cleanup and combining are also investigated to identify ways to overcome them. The last portion of the dissertation theoretically examines suppression of stimulated Raman scattering in fibers to eliminate the restriction this imposes on the power of a fiber laser or amplifier. The …

The Origin And Composition Of Aerosols In The Alaskan Airshed, Walter James Wilcox

Chemistry and Biochemistry

Since the Alaskan airshed north of the Alaska Range receives a substantial portion of its anthropogenic aerosol and gaseous pollutants through long-range transport, Alaskan air quality is influenced to an unusually high degree by the political and economic events of other countries. An understanding of the political and economic forces at work in the various circumpolar nations is key to an understanding of the observed decline in Arctic haze, the present state of Arctic air pollution, and likely future developments. It is shown in this thesis that Arctic haze has declined in Interior Alaska over the last decade and a …

Voting Rules In Insolvency Law: A Simple-Game Theoretic Approach, Matthew Braham, Frank Steffen

German Working Papers in Law and Economics

A chief characteristic of modern insolvency law in the Canada, Germany, the UK, and the US is its provision for ‘workouts’ or ‘schemes of arrangement’ by which insolvent companies can attempt to rehabilitate the business. If reorganization is chosen, the debtor has to devise a plan of action which will be voted upon by claimants. The voting rules, however, differ in each jurisdiction to a greater or lesser extent and as yet have not been analysed in any rigorous manner. This paper provides an approach based upon the theory of simple games to analyse the rules in terms of the …
