Development Of Remote Optical Instrumentation For The Enhanced Detection Of Airborne Environmental Toxins, Riley Mungo

Boise State University Theses and Dissertations

The severity of wildfires in the United States are increasing and in the amount of acreage burned due to climate change and a sustained drought in the western part of the country. As a greater number of wildfires burn in the west, the amount of smoke produced becomes a health concern to the public. Wildfires release airborne toxins and hazardous air pollutants that cause adverse health effects to the public in high concentrations but are of principle concern to health officials as they have differential impacts on infants and children. Some of the airborne toxins released are carbonyl compounds such …

The Relationship Between Motivation, Academic Achievement, And Engagement In Mathematics Using Digital Game-Based Learning: An Explanatory Sequential Mixed Methods Study, Amy Rose Morgan

Boise State University Theses and Dissertations

Digital game-based learning (DGBL) has unique factors that can engage students in the learning process. It has been shown that incorporating DGBL into mathematics can help bridge the learning gap, differentiate instruction, and engage students (Yang et al., 2018; Hulse et al., 2019; Chen et al., 2012; Naik, 2017). This study examined how students’ prior engagements are related to their academic achievement as well as investigated students’ motivation while utilizing DGBL in mathematics. An explanatory sequential mixed methods design was utilized to collect the quantitative data followed by the qualitative data. There were eighteen middle school participants in grades six …

Advancements In Measuring And Modeling The Mechanical And Hydrological Properties Of Snow And Firn: Multi-Sensor Analysis, Integration, And Algorithm Development, Tate G. Meehan

Boise State University Theses and Dissertations

Estimating snow mechanical properties – such as elastic modulus, stiffness, and strength – is important for understanding how effectively a vehicle can travel over snow-covered terrain. Vehicle instrumentation data and observations of the snowpack are valuable for improving the estimates of winter vehicle performance. Combining in-situ and remotely-sensed snow observations, driver input, and vehicle performance sensors requires several techniques of data integration. I explored correlations between measurements spanning from millimeter to meter scales, beginning with the SnowMicroPenetrometer (SMP) and instruments applied to snow that were designed for measuring the load bearing capacity and the compressive and shear strengths of roads …

Disturbance, Vegetation Co-Occurrence, And Human Intervention As Drivers Of Plant Species Distributions In The Sagebrush Steppe, Fiona Claire Schaus Noonan

Boise State University Theses and Dissertations

Changes in fire regimes, invasive species dynamics, human land use, and drought conditions have shifted important plant species in the Northern Great Basin (NGB)—including big sagebrush (Artemisia tridentata ssp.), conifers (e.g., Juniperus spp.) and invasive annual grasses (e.g., Bromus tectorum). Characterizing how these overlapping disturbances influence species distributions is critical for land management decision-making. Previous research has explored the individual effects of drought, wildfire, restoration, and invasive species on sagebrush steppe communities, but the specific effects of these disturbances in context with one another remain poorly understood at a landscape scale. To address this …

The Effect Of Right-To-Work Laws On Subjective Well-Being: A Case Study Of Oklahoma, Tyler Qualls

Boise State University Theses and Dissertations

Using Oklahoma as a case study, this thesis applies a synthetic controls model to investigate the causal effect of right-to-work (RTW) laws on the well-being of the total population with a particular focus on the most affected subset, blue-collar workers and the less educated. The effect of RTW laws leads to a significant decrease in the happiness of blue-collar workers. To be specific, while results show a possible increase in unhappiness in the total population immediately following the adoption of the RTW law, for the more vulnerable blue-collar workers, the statistically significant negative effect of the law on happiness is …

From River Channel To Cloud Tops: Evaluation And Applications Of Regional Climate Models In Mountain Watersheds, William J. Rudisill

Boise State University Theses and Dissertations

Mountain ranges are vital ”water towers” of the world and are uniquely threatened by anthropogenic climate change. At the same time, the paucity of observing networks limits our understanding of hydrometeorological processes in water-resource critical regions, including the Western United States. In the past decade, non-hydrostatic, convection permitting ( 1-4km horizontal resolution) regional climate models (RCMs) have emerged as a promising tool for both reconstructing regional scale mountain hydroclimates, and for forecasting the impacts of climate perturbations on watersheds and water-resources. Still, challenges remain. To-date, computational and data storage limitations have generally precluded many RCM studies to a handful of …

Toxicological Investigation, Identification, And Bioactivity Evaluation Of Steroidal Alkaloids Derived From Veratrum Parviflorum, Jared Taylor Seale

Boise State University Theses and Dissertations

Plants of the Veratrum genus have been used throughout history for their emetic properties, rheumatism, and for the treatment of high blood pressure. However, inadvertent consumption of these plants, which resemble wild ramps, induces life threatening side effects attributable to an abundance of steroidal alkaloids. Several of the steroidal alkaloids from Veratrum spp. have been investigated for their ability to antagonize the Hedgehog (Hh) signaling pathway, a key pathway for embryonic development and cell proliferation. Uncontrolled activation of this pathway is linked to the development of various cancers, most notably basal cell carcinoma and acute myeloid leukemia. Additional investigation of …

Time-Lapse Active Source Seismic Characterization Of A Leaky Co2 Reservoir: Little Grand Wash Fault, Utah, Stephen Slivicki

Boise State University Theses and Dissertations

A carbon capture and sequestration (CCS) approach requires economical methods to monitor reservoir CO₂ flow paths through time. I explore the use of an inexpensive surface seismic approach to monitor the time-varying response of a leaky CO₂ reservoir. My site is located in east central Utah, where the Little Grand Wash fault provides a natural analogue for a failed sequestration site. This fault and related anticlinal trap provides a conduit to collect and deliver CO₂ from shallow reservoir depths to the atmosphere. Elevated soil CO₂ flux measurements, outgassing at the Crystal Geyser, and travertine deposits provide …

Machine-Learning Reveals Aftershock Locations For Three Idaho Earthquake Sequences, Spencer F. Wilbur

Boise State University Theses and Dissertations

I explore spatial and temporal aftershock patterns related to three instrumentally recorded earthquakes in Idaho -- the Sulphur Peak, the Challis, and the Stanley earthquakes. These three M > 5 earthquakes border the eastern Snake River Plain and lie within the Intermountain Seismic Belt and Centennial Tectonic Belt. Using machine learning for event detection and phase picking from local and regional seismic networks, I generate new aftershock catalogs. I locate more aftershocks than in the USGS catalog due to lower signal-to-noise detections. Using my phase picks, I locate aftershocks using a range of velocity models and select a catalog that represents …

This multi-case study examined two public library makerspaces, and addressed these research questions: (1) How did the pandemic affect makerspace operations and access, and the teaching and learning that occurs there? (2) How did makerspace leaders respond to the challenges of the pandemic? (3) How did makerspaces evolve during the COVID-19 pandemic? I developed the Conceptual Framework for Studying the Impact of Pandemic on Public Library Makerspaces which informed the …

An Empirical Study Of Rational Addiction: The Effects Of Quitting Aids On Smoking Cessation, Cade White

Boise State University Theses and Dissertations

This paper explores the relationship between the use of quitting aids and smoking cessation using United States (US) survey data from the 2018-2019 Tobacco Use Supplement to the Current Population Survey (TUS-CPS). Becker and Murphy’s (1988) theory of rational addiction implies that strong rational addictions must terminate abruptly. In other words, strong addictions only cease by the user quitting “cold turkey”. I empirically test this hypothesis using a “double-hurdle” approach, outlined by Jones (1994). A smoker’s decision to quit and their conditional quitting success is modeled in two stages. In the first stage, a probit model is estimated for their …

A Probable Case Of Osteosarcoma: A Differential Diagnosis Of Cancers In The Ancient World, Katherine A. Hosick

Honors Theses

Ongoing archaeological investigations at the North Tombs Cemetery, Tell El-Amarna, Egypt, have, to date, yielded a skeletal sample of 141 graves and at least 252 individuals that have been recovered, representing the non-elite responsible for erecting, and inhabiting a new city (c. 1353 BCE) (Dabbs, 2020) . Recent data on the recovered remains show a trend toward pathological changes in the skeletons attributable to occupational stress-related injuries, specifically those associated with demanding physical labor. One individual (Individual 1154), who was buried wrapped in textile, as is typical of the cemetery exhibited an abnormal bony abnormal bony proliferative lesion on the …

Reading Section 230, Shlomo Klapper

Buffalo Law Review

In Gonzalez v. Google, the Supreme Court, for the first time, agreed to hear a case concerning the interpretation of Section 230 of the Communications Decency Act, the most important law governing the internet. As Justice Thomas and others have noted, judges have overlooked Section 230’s text in interpreting the statute, relying instead on purpose. Yet scholars and critics, too, have eschewed the statutory text, relying on intent or consequences to favor alternate interpretations, but depriving the Court and litigants of the richness the statutory text offers.

This Article offers the first comprehensive analysis of Section 230’s text and structure. …

Measuring Judicial Collegiality Through Dissent, Jonathan Remy Nash

Buffalo Law Review

While scholars frequently offer ideology as a primary explanation for judicial behavior, judges, and some scholars, emphasize the importance of collegiality on multimember courts. But there is disagreement over how to determine when collegiality is at work, and what type of multimember court is more likely to exhibit collegiality among its judges. Resolving these competing claims calls for a valid measure of collegiality.

This Article develops novel measures of collegiality based on dissenting judges’ expressions of collegiality towards judges in the majority. It uses judge-level and court-level databases to validate these measures by showing that the novel measures correlate with …

Inspection Of Flexible Fillers In Post-Tensioned Bridges, Carley Gonzalez

Doctoral Dissertations and Master's Theses

The Florida Department of Transportation (FDOT) is currently pushing toward the use of flexible fillers (FF) in new post-tensioned (PT) bridges. Flexible fillers have several advantages compared to the currently used cementitious grouts (CG) and can offer longer-lasting structures by providing better corrosion protection and allowing for replaceable tendons, which reduces the overall maintenance costs over the structure’s lifespan. Due to these fillers being used in new bridges, FDOT needs effective nondestructive evaluation (NDE) methods to employ in their biennial inspections. There are currently numerous NDE methods available to inspectors that have been used to identify defects in PT bridges …

Time-Dependent Photoionization Modeling Of Warm Absorbers In Active Galactic Nuclei, Dev Raj Sadaula

Dissertations

Warm absorber spectra are bound-bound and bound-free absorption features, seen in the X-ray and UV spectra from many active galactic nuclei (AGN). The widths and centroid energies of these features indicate they occur in outflowing gas moving with hundreds to thousands of km/s. Depending upon the energy and momentum of the outflow, it can affect the gas within the host galaxy. Thus, warm absorbers’ mass and energy budgets are of great interest. Estimates for these properties depend on models that connect the absorption features' observed strengths with the density, composition, and ionization state of the absorbing gas. Such models assume …

Evidence For An Early Saginaw Lobe Ice Retreat And Drainage Adjustments Across Southern Michigan, Usa, Nathan Erber

Dissertations

The Saginaw lobe of the Laurentide Ice Sheet (LIS), flowed out of Saginaw Bay, across Lower Michigan and into northern Indiana. As it retreated, the Saginaw lobe deposited the Sturgis moraine, a recessional moraine of the lobe in southern Michigan. Positioned to the west and east of the Saginaw lobe were the Lake Michigan and Huron-Erie lobes, respectively. These lobes retreated across the region asynchronously, with the Saginaw lobe retreating first. The asynchronous behavior of the lobes allowed for the Lake Michigan and Huron-Erie lobes to overprint and alter landscapes once occupied by the Saginaw lobe ice.

The Kalamazoo moraine, …

Balance Recovery Response In Community-Dwelling Adults With Unilateral Transtibial Amputation And The Potential Benefits Of A Weight-Shifting Balance Training Intervention, Hui-Ting Shih

UNLV Theses, Dissertations, Professional Papers, and Capstones

Previous studies have shown that individuals with various physical, sensory and neuromuscular impairments are at higher risks of falls. Individuals with unilateral transtibial amputation (UTTA) suffered from all these impairments, and tripping not surprisingly caused a considerable number of falls in this population. To study falls, researchers have to put participants in a well-protected environment and reproduce tripping fall scenarios. Furthermore, the perturbation delivery needs to be precise in terms of temporo-spatial timing. These features would ensure the quality of responses elicited and reproducibility of the results. Thus, in Chapter 2, we developed a treadmill-based perturbation delivery protocol and confirmed …

Constraints To Wilderness Recreation: A Scoping Review Of Existing Research, Elena R. Thomas, William L. Rice, Jaclyn R. Rushing, Jennifer M. Thomsen, Christopher A. Armatas

Society and Conservation Faculty Publications

Considerable research has been conducted on the constraints to recreation that traditionally underrepresented communities in the United States confront; however, there remains a lack of synthesis concerning constraints to visitation to federally designated wilderness areas. This scoping review of the current available literature seeks to reveal what constraints have been identified to visitation to federally designated wilderness in the United States and what groups are experiencing them. Constraints identified include discomfort and safety concerns specific to wilderness settings, cultural expectations, and issues of time, cost, and access. Additionally, constraints are explored with reference to the influence of management actions focused …

Attachment And Older Adults In Psychotherapy: A Latent Profile Analysis Of Psychological Distress Across Treatment, Brian Michael Stran

Dissertations

Older adults have been largely underrepresented within the psychotherapy literature. Given the unique social and emotional changes associated with older age (Carstensen et al., 1999) and the perceived gap in training that trainees report in working with older adults (Woodhead et al., 2015), there is a pressing need for research that can aid mental health practitioners in the conceptualization, treatment planning, and treatment of their older adult clients.

In the first part of this manuscript, an integrated theoretical model, consisting of socioemotional selectivity theory (SEST; Carstensen et al., 1999) and attachment theory (Bowlby 1969), was developed to provide psychotherapists with …

Sorption Of Cellulases In Biofilm Enhances Cellulose Degradation By Bacillus Subtilis, Yijie Deng, Shiao Y. Wang

Faculty Publications

Biofilm commonly forms on the surfaces of cellulosic biomass but its roles in cellulose degradation remain largely unexplored. We used Bacillus subtilis to study possible mechanisms and the contributions of two major biofilm components, extracellular polysaccharides (EPS) and TasA protein, to submerged biofilm formation on cellulose and its degradation. We found that biofilm produced by B. subtilis is able to absorb exogenous cellulase added to the culture medium and also retain self-produced cellulase within the biofilm matrix. The bacteria that produced more biofilm degraded more cellulose compared to strains that produced less biofilm. Knockout strains that lacked both EPS and …
