This report describes a project involving the design, implementation, and testing of a software development framework, called JeroMF, that can help developers create scalable distributed applications based on a microservice architecture and that uses JeroMQ (a native Java implementation of ZeroMQ) for message passing. JeroMF provides an execution framework and extensible components for implementing processes, services, communication channels, messages, communication statistics, and encryption. Applications built with JeroMF do not require a message broker or any other middleware processes. However, they may include an optional Service Registry that can facilitate for service discovery and secure communications. The Service Registry itself was ...


Assessing Beaver Dam Dynamics In The Logan-Little Bear Watershed, Connor Penrod Dec 2019

Assessing Beaver Dam Dynamics In The Logan-Little Bear Watershed, Connor Penrod

All Graduate Plan B and other Reports

This paper seeks to address a knowledge gap concerning how flood events impact beaver dams over time. To address this gap, I took four time-snapshots of beaver dams, mapping them across the Utah portion of the Logan-Little Bear watershed, from 2009 to 2016 to bookend a large flood event in 2011. I assessed dam status (intact, breached, or blown out) for each dam mapped to assess the impact of the large spring runoff on the dam status. Assessing dam status over time allowed me to assess the change in condition over time, from before to several years after, while also ...


Modern Uses Of Assistance Animals In The Usa: Definitions, Access, And The Laws That Protect Them, Tina Reisner Dec 2019

Modern Uses Of Assistance Animals In The Usa: Definitions, Access, And The Laws That Protect Them, Tina Reisner

All Graduate Plan B and other Reports

One of the most arguable issues in our society, and within the field of modern disability policy and law is the epidemic surrounding the use of service animals. With several cases for and against the use of service animals in public entities, there is constant discussion of what is a legitimate service animal and who is able to utilize them. In this thesis, I establish the definition of disability and discuss the laws and policies that legitimized the use of service animals within the public sphere. Specifically, this work will draw upon genres such as policies and laws of disability ...


Enteric Methane And Nitrogen Emissions In Beef Cattle Grazing A Tannin-Containing Legume Relative To Feedlot And Traditional Pasture-Based Production Systems, Raúl David Guevara Ballesteros Dec 2019

Enteric Methane And Nitrogen Emissions In Beef Cattle Grazing A Tannin-Containing Legume Relative To Feedlot And Traditional Pasture-Based Production Systems, Raúl David Guevara Ballesteros

All Graduate Theses and Dissertations

Beef cattle production is highly criticized because of the high use of land and water resources, and by the pollution (e.g., the gas methane in a cow’s breath and nitrogen in urine) produced by cows fed in feedlots. In contrast to feedlots diets and grasses, some plants (e.g., legumes) contain bioactive compounds (condensed tannins) that reduce pollution and enhance animal nutrition. In my research, I observed that cows grazing a tannin-containing legume (birdsfoot trefoil; BFT) had methane emissions similar to cows fed a feedlot ration with comparable weight gains. Cows in the BFT treatment gained more weight ...

Then it presents the design ...


Responding To Microaggressions: Evaluation Of Bystander Intervention Strategies, Tianyi Xie Dec 2019

Responding To Microaggressions: Evaluation Of Bystander Intervention Strategies, Tianyi Xie

All Graduate Theses and Dissertations

Ethnic minorities often experience microaggressions that cause psychological distress and increase health risks. Bystander interventions are good ways to intervene when microaggressions take place and provide emotional support for ethnic minority targets. White interveners and interventions that pose low threats to White aggressors are perceived more positively than ethnic minority interveners and interventions that are more confrontational and direct. Furthermore, a support-based intervention that validates White aggressors’ good intention and effort without judgement may help White aggressors feel less defensive and more receptive to the intervention. Asian Americans face unique microaggressive themes and their racial experiences are influenced by the ...

The three stories featured within this thesis are offered as a way to understand these challenges. Each protagonist is faced with an issue of morality, sexuality, or ceremony, and each reach differing conclusions about these topics within their lives ...


Gender And Social Acceptance Of Immigrants In A New Destination Site, Emma Meade Earl Dec 2019

Gender And Social Acceptance Of Immigrants In A New Destination Site, Emma Meade Earl

All Graduate Theses and Dissertations

In this article, I draw on secondary interview data with LatinX immigrants in Cache Valley, Utah, an emerging new destination site in the Inter-Mountain West. While immigrants are drawn to new destinations by employment opportunities, quality of life, or low cost of living, they face many challenges in integrating socially into fairly homogenous communities, which can be particularly challenging for immigrant women. This thesis analyzes the ways in which gender affects social integration in the specific cultural and demographic context of Cache Valley. Using interviews with 16 men and women, I examine gender differences in perceptions of the community, experiences ...


Preschool Science: An Examination Of Classroom And Teacher Predictors, Donna S. Blaylock Dec 2019

Preschool Science: An Examination Of Classroom And Teacher Predictors, Donna S. Blaylock

All Graduate Theses and Dissertations

Science experiences during the preschool years is important because it helps build brain development in children, and improves school readiness. This exploratory study examined several characteristics of teachers and classrooms to see if any factors predicted time spent on science. Over 120 teachers participated, with teachers from Head Starts, university child development laboratories, home-based preschools, and other private preschool programs.

Findings suggest that preschool teachers are quite comfortable with teaching science, but science activities are reported to occur infrequently—one to three times a month. Teachers with higher levels of education and comfort levels with science are reported to be ...


Staff Perceptions Of Quality Interactions In Dementia Care, Rebecka A. Schultz Dec 2019

Staff Perceptions Of Quality Interactions In Dementia Care, Rebecka A. Schultz

All Graduate Theses and Dissertations

The national aging trend suggests that population of those aged 65 and older will reach 83.7 million by the year 2050. With increasing age comes the growing possibility of one getting some form of dementia. The Alzheimer’s Association expects the number of American’s with dementia to triple from the reported 5 million cases in 2014 by 2050. With a rise in this cognitively impaired population there is reason to look closely at the needs of persons with dementia living in residential facilities and whether or not they are being met. The main focus of residential facilities is ...


Development And Testing Of A Hydrogen Peroxide Injected Thrust Augmenting Nozzle For A Hybrid Rocket, Mark C. Heiner Dec 2019

Development And Testing Of A Hydrogen Peroxide Injected Thrust Augmenting Nozzle For A Hybrid Rocket, Mark C. Heiner

All Graduate Theses and Dissertations

During a rocket launch, the point at which the most thrust is needed is at lift-off where the rocket is the heaviest since it is full of propellant. Unfortunately, this is also the point at which rocket engines perform the most poorly due to the relatively high atmospheric pressure at sea level. The Thrust Augmenting Nozzle (TAN) investigated in this paper provides a solution to this dilemma. By injecting extra propellant into the nozzle but downstream of the throat, the internal nozzle pressure is raised and the thrust is increased, and the nozzle efficiency, or specific impulse is potentially improved ...

The Response Of Utah Lake's Plant And Algal Community Structure To Cultural Eutrophication, Leighton R. King

All Graduate Theses and Dissertations

Human activities have long had a negative impact on the water quality of freshwater lakes around the world. Utah Lake, located in north-central Utah, has been a subject of such impacts, as the lake experiences recurrent harmful algal blooms during the summer months. Lake warnings and closures have made the public increasingly aware of the ecological and economic impact of these blooms. The objectives of this study were to: 1) compare historical and present-day water quality and ecosystem conditions using environmental data contained in sediment cores, 2) identify whether, and when, Utah Lake transitioned from clearwater to turbid conditions, and ...


Public Transportation Accessibility: Perceptions Of Riders With Disabilities In Utah, Cherissa R. Alldredge Dec 2019

Public Transportation Accessibility: Perceptions Of Riders With Disabilities In Utah, Cherissa R. Alldredge

All Graduate Theses and Dissertations

Transportation plays an essential role in social inclusion and participation, subjective well-being, and overall quality of life. A lack of private transportation options may make individuals with disabilities more dependent on public transportation systems. Despite increased use, people with disabilities continue to report barriers accessing public transportation services. Interestingly, little is known about these barriers at the regional transportation district level. The purpose of this study was to better understand the barriers and perceived accessibility of the Utah Transit Authority’s (UTA) public transportation system for individuals with disabilities living within the UTA service area.

Using an online survey, data ...

Activity Tracker Measurement Of Physical Activity And Sedentary Time In The Workplace Including An Intervention Involving Reminders To Move, Cassie Dance

All Graduate Theses and Dissertations

Sedentary time and physical inactivity have negative impacts on health and health costs as well as an impact on workplace wellbeing. There is evidence that people are more sedentary and engage in less physical activity on work days. Additionally, sedentary behavior has been found to increase distress and negative mood. Activity trackers such as Fitbits are a useful way to collect and intervene on sedentary behavior and potentially impact other factors of workplace wellbeing in real time and promote self-monitoring. The reminder to move prompts that are now part of Fitbit models provide an innovative and simple way to intervene ...


The Processes Of Collective Buy-In, Actuation, And Deep Social Learning In Seminary Classes, Donald B. Anderson Dec 2019

The Processes Of Collective Buy-In, Actuation, And Deep Social Learning In Seminary Classes, Donald B. Anderson

All Graduate Theses and Dissertations

This phenomenological study explored a common essence of collective class actuation (CCA) among six seminary teachers in a Western state. CCA is an optimal learning state of a class collective. Data were gathered through interviews, observations, and a focus group. Data analysis yielded themes, textural and structural descriptions, an overall essence, and a model explaining the processes of buy-in and actuation.

Findings indicate that seminary teachers seek to actuate their classes by leading them toward agentic, collective buy-in. This requires management of two social environments: the internal social environment (the heart) and the external social environment. The internal social environment ...


Rural Aging: The Geographic Reach Of Service Access In Utah, Identifying Barriers And Solutions, Alexandra T. Schiwal Dec 2019

Rural Aging: The Geographic Reach Of Service Access In Utah, Identifying Barriers And Solutions, Alexandra T. Schiwal

All Graduate Theses and Dissertations

This dissertation includes two studies of rural age-related services in the state of Utah. The first study combines geospatial, demographic data (number of people over 55) and age-related services (hospitals, hospice providers, nursing homes, senior centers, and Areas Agencies on Aging) at the county level and census-tract level to determine localized differences in proportional access to age-related services. Higher and lower proportions are then predicted by contextual factors including rural/urban gradient, economic industry, and broadband access. Results demonstrate that broadband access was significantly associated with higher access to age-related services, but being a retirement destination (increase in people over ...


Reducing Thermal Bridging And Understanding Second-Order Effects In Concrete Sandwich Wall Panels, Taylor J. Sorensen Dec 2019

Reducing Thermal Bridging And Understanding Second-Order Effects In Concrete Sandwich Wall Panels, Taylor J. Sorensen

All Graduate Theses and Dissertations

Structural engineers have traditionally detailed structures with structural and fabrication efficiency in mind, but often based on a limited understanding of thermal efficiency. Some connection designs can create significant thermal bridging, leading to unnecessary heat transfer and even premature degradation through condensation. Thermal bridging occurs when heat transfer is given a path through a more conductive material like concrete or steel rather than insulation. Concrete sandwich wall panels (SWP) tend to be highly efficient at preventing heat transfer in the middle of panels, with greatest heat transfer occurring at connections. This project identified thermally efficient details for future SWP construction ...


The Effects Of Fluctuations In Federal Revenue Sharing Payments Made To Rural Counties On School District Budgets, Camille Harmer Dec 2019

The Effects Of Fluctuations In Federal Revenue Sharing Payments Made To Rural Counties On School District Budgets, Camille Harmer

All Graduate Theses and Dissertations

Federal revenue sharing programs aim to make up lost tax revenue to counties that contain federal land, as counties do not receive any property tax revenue from publicly owned lands. This may have a significant impact on rural school districts with a limited tax base, as most funding for public education comes from property tax revenue. My analysis seeks to determine the full impact of certain federal revenue sharing payments (paid out by the U.S. Forest Service) on school districts in counties that contain U.S. Forest Service land. My analysis shows that the payments have little impact on ...


Plug-And-Play Web Services, Arihant Jain Dec 2019

Plug-And-Play Web Services, Arihant Jain

All Graduate Theses and Dissertations

The goal of this research is to make it easier to design and create web services for relational databases. A web service is a software service for providing data over computer networks. Web services provide data endpoints for many web applications. We adopt a plug-and-play approach for web service creation whereby a designer constructs a “plug,” which is a simple specification of the output produced by the service. If the plug can be “played” on the database then the web service is generated. Our plug-and-play approach has three advantages. First, a plug is portable. You can take the plug to ...


Relationship Maintenance Behaviors And Marital Stability In Remarriage: The Examination Of Stepfamily Constellations And Associated Challenges, Ron C. Bean Dec 2019

Relationship Maintenance Behaviors And Marital Stability In Remarriage: The Examination Of Stepfamily Constellations And Associated Challenges, Ron C. Bean

All Graduate Theses and Dissertations

Research on stepfamily life in the 21st century reveals unexplored variables at every turn. This is important because around half of American adults report close step-relationships and the challenges and demographic and relational differences for different types of stepfamilies remains unexplored. The first of these studies explored data for 879 husbands and wives couples to explore how positivity, negativity, and sexual interest levels differ depending which of the couple, both partners, or neither had previous children. Wives reported higher levels of marital instability and positivity than husbands. Marital instability was linked with one’s own and one’s partners’ negativity ...


The Determinants Of Municipal Minimum Wage Ordinances: An Analysis Of 100 Large Cities From 2012-2017, Nicholas S. Hilton Dec 2019

The Determinants Of Municipal Minimum Wage Ordinances: An Analysis Of 100 Large Cities From 2012-2017, Nicholas S. Hilton

All Graduate Theses and Dissertations

The city of Seattle, Washington made headlines in 2014 when its city council enacted the highest minimum wage in the history of the United States. The ruling appeared to begin a trend as similar policies began diffusing in cities across the country. In reality, however, municipal minimum wage ordinances have existed since the early 1990’s. Yet, despite over two decade’s worth of data on the subject, little research has been conducted to understand the characteristics that influence cities to enact minimum wages in the first place. This study contributes to our understanding of the predictors of minimum wage ...


Energy Management Of Dynamic Wireless Power Transfer Systems For Electric Vehicle Applications, Ahmed N. Azad Dec 2019

Energy Management Of Dynamic Wireless Power Transfer Systems For Electric Vehicle Applications, Ahmed N. Azad

All Graduate Theses and Dissertations

Wireless power transfer is a method of transferring electric power from a transmitter to a receiver without requiring any physical connection between the two. Dynamic Wireless Power Transfer (DWPT) entails having the transmitters buried under the roadway and the receiver unit being installed on the Electric Vehicle (EV). In this method, EVs are charged while driving over the transmitters as they receive bursts of electric energy at the time of significant alignment between transmitters and receivers. Compared to the stationary charging method which involves parking the EV for long hours for a full charge, the dynamic charging method (i.e ...

Power V. Threhsold: Near-Channel Morphology Controls Sediment Rating Curve Shape In Coastal Redwood Watersheds, Adam Caspian Nebraska Fisher

All Graduate Theses and Dissertations

River sediment is one of the most pervasive pollutants in the world. Excess amounts of fine sediment can reduce water quality, damage stream ecosystems, and harm aquatic life. Both natural and human-caused processes can add sediment to a river, such as tectonic uplift, landslides, and timber harvesting. Therefore, it is important to understand how fine sediment enters and moves through a rive system to inform policymakers and land-managers on effective ecosystem management.

In this study, we determined how the relationship between river flow and suspended sediment changed among watersheds along the North Coast of California. We found a rise in ...


Herbage Characteristics Affecting Intake By Dairy Heifers Grazing Grass-Monoculture And Grass-Birdsfoot Trefoil, Marcus F. Rose Dec 2019

Herbage Characteristics Affecting Intake By Dairy Heifers Grazing Grass-Monoculture And Grass-Birdsfoot Trefoil, Marcus F. Rose

All Graduate Theses and Dissertations

Pasture-based dairies have become more prevalent in recent years due to a higher proportion of organic milk demand and production. Organic certification requires that animals must graze at least 120 days in each growing season. However, dry matter intake is often limited when dairy animals receive most of their herbage from pasture, resulting in lower animal performance and milk production. The purpose of this study was to analyze the complimentary effect of high energy grasses with birdsfoot trefoil (BFT) tannins to improve intake of dairy heifers. Jersey heifers were rotationally grazed for 105 days in 2017 and 2018 on eight ...

Foreground Removal In A Multi-Camera System, Daniel T. Mortensen Dec 2019

Foreground Removal In A Multi-Camera System, Daniel T. Mortensen

All Graduate Theses and Dissertations

Traditionally, whiteboards have been used to brainstorm, teach, and convey ideas with others. However distributing whiteboard content remotely can be challenging. To solve this problem, A multi-camera system was developed which can be scaled to broadcast an arbitrarily large writing surface while removing objects not related to the whiteboard content. Related research has been performed previously to combine multiple images together, identify and remove unrelated objects, also referred to as foreground, in a single image and correct for warping differences in camera frames. However, this is the first time anyone has attempted to solve this problem using a multi-camera system ...
