The goals of this study were to: 1) describe the distribution and abundance of anguilliform eel leptocephali across the northern Gulf of Mexico, and 2) examine the trophic ecology of leptocephali using stable isotope values of carbon and nitrogen (δ13C and δ15N). A 25-year (1990-2014) ichthyoplankton dataset provided by the National Oceanic and Atmospheric Administration (NOAA) Southeast Area Monitoring and Assessment Program (SEAMAP) was used to examine interannual variations in leptocephalus distribution, …

Terrorism And Organized Crime: An Analytical Study From An International Law Perspective, Leila Mejdoubi

Master's Theses

With the spread of terrorism and its growing risks since the start of the 21^st century, a wide range of reports and studies have emerged. This funding comes from a special relationship between terrorist organizations, organized crime syndicates, and their cooperation with each other, which has enabled terrorist organizations in particular to carry out recruitment efforts and operations alike. It has also fueled an international black market for smuggling and trade in drugs and arms. Under what conditions do violent terrorist groups driven by extreme Islamist ideology collaborate with organized criminal enterprises to generate the requisite resources to pursue …

The Monkey Queen: Creating Cultural Connections Through Theatre For Young Audiences, Matt Loehrke

Master's Theses

Youth in America have access to numerous stories on stage, page, and screen, yet many of those tales originate from white, Euro-centric cultures. Current trends in American theatre often produce familiar scripts to present to their communities. Unfortunately, too often, stories from other cultures are not adapted and presented. This thesis seeks to provide a culture bridge by adapting one of China’s most beloved stories, The Monkey King, for a young American audience through the medium of Theatre for Young Audiences. Theatre is a great unifier; however, the most critical audience, the audience that will grow into the next generation …

Resource-Constrained Project Scheduling With Autonomous Learning Effects, Jordan M. Ticktin

Master's Theses

It's commonly assumed that experience leads to efficiency, yet this is largely unaccounted for in resource-constrained project scheduling. This thesis considers the idea that learning effects could allow selected activities to be completed within reduced time, if they're scheduled after activities where workers learn relevant skills. This paper computationally explores the effect of this autonomous, intra-project learning on optimal makespan and problem difficulty. A learning extension is proposed to the standard RCPSP scheduling problem. Multiple parameters are considered, including project size, learning frequency, and learning intensity. A test instance generator is developed to adapt the popular PSPLIB library of scheduling …

A Description Of Lichen Community Structure And The Impacts Of Spruce Beetle Disturbance In Northwestern Colorado, Anna Freundlich

Master's Theses

Spruce beetle disturbance has affected millions of acres of forest throughout North America and Europe, but thus far little research has investigated how this disturbance influences lichen communities. To address this problem, we studied lichen communities and habitat characteristics within 44 plots across a chronosequence of spruce beetle damage spanning 1996–2017 in northwestern Colorado. We found 82 species of lichens, few habitat differences among spruce beetle disturbance classes, and only the most recently affected plots (2012–2017) had significantly different lichen community structure relative to remaining areas. Two primary gradients explained the majority of variation of lichen community structure within our …

Characterizing The Susceptibility And Type I Interferon Response Of Primary Mammalian Cells During Zika Virus Infection, Douglas Petty

Master's Theses

Zika virus (ZIKV), a member of the genus Flavivirus, has become a major public health concern since 2007. During the most recent 2015 outbreak, ZIKV rapidly spread from South America to over 84 countries and territories across the world in two years. ZIKV has also been associated with previously uncharacterized neurological manifestations during the 2013 and 2015 outbreaks. The novel manifestations include Guillain-Barré Syndrome (GBS) in adults and Congenital Zika Syndrome (CZS) in newborns. GBS is a progressive paralysis caused by damage to the peripheral nervous system; while CZS is an all-encompassing term for the severe neurological and developmental complications …

The Water Table, Soil Moisture And Evapotranspiration Conditions Following The Removal Of Conifers From Two Encroached Meadows, Tyler J. Davis

Master's Theses

Montane meadows provide essential habitat for a variety of unique species and important ecosystem services in the western United States. Although important, meadows have experienced increased rates of conifer encroachment due to climate change, fire suppression and grazing. To combat meadow degradation from conifer encroachment, land managers have employed various restoration strategies one of which is conifer removal. Multiple studies have investigated the relationship between meadow hydrology and vegetation; however, few have assessed the effect of conifer removal on meadow groundwater. The goal of this study is to determine if the removal of conifers from an encroached meadow has an …

Evaluating Urban Downtown One-Way To Two-Way Street Conversion Using Microscopic Traffic Simulation, Bernice Liu

Master's Theses

Located in the heart of Silicon Valley, Downtown San Jose is attracting new residents, visitors, and businesses. Clearly, the mobility of these residents, visitors, and businesses cannot be accommodated by streets that focus on the single-occupancy automobile mode. To increase the potential for individuals to use non-single-occupancy modes of travel, the downtown area must have a cohesive plan to integrate multimodal use and public life. Complete streets are an integral component of the multi-modal transport system and more livable communities. Complete streets refer to roads designed to accommodate multiple modes, users, and activities including walking, cycling, transit, automobile, and nearby …

Written In Black, White, And Red: An Exploration Of Civilizer Theology In American History, Jeremy Mcginniss

Master's Theses

This paper proposes an extended definition and discusses examples of civilizer theology within the perceptions and practices of white Protestant American Christianity faith traditions. Civilizer theology is defined as a self-referential, self-fulfilling framework actively shaping the expectations, behaviors and practices of societal norms driving cultural practices. Examples are selected as guided by three significant and interdependent dispositions characterizing civilizer theology: cultural decay/moral decline, authority, and violence. This paper hypothesizes theological interpretation, application and exegesis, mediated by the three dispositions, are deliberately applied to support socio-economic, cultural and political ends with the goal of maintaining power structures benefiting a particular group.

Effects Of Intertidal Position On Metabolism And Behavior In The Acorn Barnacle, Balanus Glandula, Kali Horn

Master's Theses

The intertidal zone is characterized by persistent, tidally-driven fluctuations in both abiotic (e.g., temperature, [O₂], salinity) and biotic (e.g., food availability, predation) conditions, which makes this a very physiologically challenging habitat for resident organisms. The magnitude and degree of variability of these environmental stressors differs between intertidal zones, with the most extreme physiological stress often being experienced by organisms in the high intertidal. Given that many of the fluctuating conditions in this environment are primary drivers of metabolic rate (e.g., temperature, [O₂], food availability), we hypothesized that sessile conspecifics residing in different tidal zones would exhibit …

Mesoscale Controls On The Shasta County Convergence Zone, Matthew Thomas Roberts

Master's Theses

The Shasta County Convergence Zone (SCCZ) is a poorly understood terrain-forced convergence zone that develops at the northern terminus of California’s Sacramento Valley during cool season (Oct.-Apr.) trough passages. While terrain-flow interactions clearly factor into the SCCZ development, the nature of these interactions is unknown as are the mesoscale processes affecting event duration and orientation. Level-II NEXRAD radar data are used to examine the onset, duration, orientation, geographical extent, and precipitation rate of 23 SCCZ events during the 2016-2017 cool season. The analyses reveal distinct event morphologies including (1) isolated convective bands over the topography, (2) isolated convective bands displaced …

The Energetic Cost Of Anthropogenic Disturbance On The Southern Sea Otter (Enhydra Lutris Nereis), Heather Elizabeth Barrett

Master's Theses

With increased human populations and tourism in coastal areas, there is greater potential for disturbance of marine wildlife. Having high metabolic rates, sea otters (Enhydra lutris nereis) are at risk of increased energetic costs due to disturbance. To investigate these effects, sea otter activity in response to potential disturbance stimuli was recorded over three years, at three California locations: Monterey, Moss Landing, and Morro Bay. A hidden Markov Model was developed to examine how activity varies as a function of location, group size, pup to adult ratio, kelp canopy, and occurrence of and proximity to disturbance stimuli. Results were combined …

Children's Books As Cultural Products: A Qualitative Study Of Cultural Representation In Hmong And Non-Hmong American Books, Malina Her

Master's Theses

This study examined the type of cultural practices and values depicted within Hmong American children’s books in comparison to non-Hmong American children’s books from the United States. The purpose was to explore if prior Hmong traditional practices and values reflective of American individualism would extend to Hmong children’s books. Thirty best-seller children’s books were coded using two checklists, one focused on Hmong traditional practices and the other on American values. Results showed that Hmong traditional practices underscored by Hmong adolescents in prior research somewhat extended to Hmong children’s books. Moreover, in some respects Hmong children’s books displayed similar numbers of …

Effect Of Nicotine Exposure On Fatigue Mechanics Of Murine Arteries, Elizabeth Ho

Master's Theses

Nicotine is an addictive substance found in electronic cigarettes (e-cigarettes) and cigarettes, and the use of such products has growing concern because of the prevalent use by young adults. Nicotine exposure degrades arterial tissue and results in increased arterial stiffness, which is linked to cardiovascular events, such as stroke and myocardial infarction. The hypothesis of this research is that fatigue loading reveals changes to the mechanical behavior of nicotine-treated arteries that is more informatively discriminating than stiffness alone. Ten murine arteries, five untreated and five nicotine-treated, were subjected to cyclic fatigue loading in an open-circumferential configuration by a custom tensometer …

A Phonetic Distance Approach To Intelligibility Between Mam Regional Dialects, Megan Simon

Master's Theses

Mam, an indigenous Mayan language spoken primarily in Guatemala, has considerable internal diversity among its regional dialects. The purpose of this thesis is to estimate their varying degrees of intelligibility and to present groups of dialects whose speakers can be reasonably expected to understand one another. The analysis consists of two parts, the computation of a phonetic distance network and a series of sociocultural interviews. Phonetic distance was measured by Levenshtein distance between cognates in word lists and analyzed with a Neighbor-Net network. Interviews with Mam speakers focused on subjective judgments of intelligibility, contact, and social attitudes. Four main dialect …

Utilizing Trajectory Optimization In The Training Of Neural Network Controllers, Nicholas Kimball

Master's Theses

Applying reinforcement learning to control systems enables the use of machine learning to develop elegant and efficient control laws. Coupled with the representational power of neural networks, reinforcement learning algorithms can learn complex policies that can be difficult to emulate using traditional control system design approaches. In this thesis, three different model-free reinforcement learning algorithms, including Monte Carlo Control, REINFORCE with baseline, and Guided Policy Search are compared in simulated, continuous action-space environments. The results show that the Guided Policy Search algorithm is able to learn a desired control policy much faster than the other algorithms. In the inverted pendulum …
