Aspen seedlings for boreal mine reclamation

Bradley Pinno

Trembling aspen is a major component of the forests in Alberta. Aspen is an early successional species which occurs in both pure and mixed stands. It also provides the timber for pulp mills and oriented strand board mills with a harvest rate of nearly 12M m³ (5.08 BBF) of aspen timber annually in Alberta. Aspen normally regenerates vigorously after disturbance from root suckers in the range of 10,000–100,000 stems per hectare. However, after industrial disturbances such as mining or the creation of well sites where the soil has been removed, root …

Storing Water For The Environment: Operating Reservoirs To Improve California’S Freshwater Ecosystems, Sarah Null, Jeffrey Mount, Brian Gray, Kristen Dybala, Gokce Sencan, Anna Sturrock, Barton Thompson, Harrison Zeff

Watershed Sciences Faculty Publications

California’s freshwater ecosystems—its lakes, rivers, floodplains, meadows, natural and managed wetlands, and estuaries—are a vital part of the state’s natural infrastructure. These ecosystems provide numerous benefits, including water supply, hydropower, flood control, fisheries, recreation, and cultural and aesthetic value. They are also home to the nation’s most diverse array of plant and animal communities, with numerous freshwater species found only in California (Jensen et al. 1993; Grantham et al. 2017).

Storing Water For The Environment: Technical Appendix B: An Experimental Reservoir Model For Storage And Allocation Of An Ecosystem Water Budget, Sarah Null, Harrison Zeff, Anna Sturrock

Watershed Sciences Faculty Publications

Dams alter flow regimes, fragment rivers, and harm freshwater ecosystems (Munsch et al. 2022; Barbarossa et al. 2020). Yet, freshwater ecosystems are increasingly dependent on surface reservoirs for environmental flows and suitable water temperatures as rivers have become irrevocably altered by water development, consumptive water uses, land use change, and climate change (Grantham et al. 2020; Yarnell et al. 2020). This creates a paradox where dams have contributed to freshwater ecosystem decline, but are now instrumental for managing environmental water and enhancing downstream ecosystems.

Reversing The Gaze: Using Indigenous And Western Worldviews To Compare Coverage Of Climate Change And Indigenous Peoples In The News Media, Gina Mccrackin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The news media acts as an important conduit for shaping societal views of the socio-politics of climate change. While climate change will indeed affect everyone, it will not affect everyone equally. Indigenous peoples are among the populations whose well-being is threatened the most by climate change. International scholarship finds it is not uncommon for Indigenous cultures, communities, and perspectives to be underrepresented and misrepresented in Western climate change media. Research also indicates that fair Indigenous representation occurs when Indigenous peoples are the authors of news articles themselves. We evaluated the differences in discussions of climate change and environmental issues …

Intra-Operative Language Assessment For Adult Brain Tumor Survivors: A Systematic Review, Carissa Jolley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Awake craniotomy and language assessment procedures for brain tumor survivors can drastically affect patient outcomes and quality of life. The goal of intra-operative language mapping is to help preserve vital communicative functions. However, there is currently no standardized set of measures for intra-operative language assessment. This systematic review identified behavioral language measures used during intra-operative procedures and the resulting outcomes for adult brain tumor patients, with the aim of helping clinicians and researchers select intra-operative language assessments supported by the highest levels of evidence.

PRISMA guidelines were used to systematically identify articles. Patient demographic and medical information, neuroimaging data, intra-operative …

Investigating Cause-Specific Mortality Of Sheep To Determine The Impacts Of Carnivores On Domestic Livestock, Nathan Jacob Floyd

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Livestock and carnivores interact in ways that are considered conflict throughout the world. In the western United States, livestock are often grazed on public lands in close proximity to predators in their natural habitat, and can be killed as prey. Livestock losses to predators can threaten rancher’s livelihoods. Sheep and lambs are especially vulnerable to predators due to their small size and lack of defensive abilities. To reduce the impacts that predators have on livestock, it is important for ranchers and wildlife biologists to have an accurate understanding of how many livestock die and are killed by predators when grazing …

The Personal Is Still Political: An Analysis Of Jessica Valenti's Contemporary Feminine Style, Michala M. Zilkey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 2016, Jessica Valenti’s memoir, Sex Object, was published. Sex Object describes Valenti’s experiences of sexualization and objectification in a personal and anecdotal format. The feminine style, a rhetorical style that bridges the divide between norms of femininity and expectations of public oration, has been heralded as essential for advancing the feminist movement. This thesis asks the question, to what extent does contemporary feminists’ rhetoric mirror and diverge from earlier iterations of the feminine style? I argue that Valenti’s employs a feminine style that utilizes relational norms and self-disclosure to illustrate the personal as political and the political as …

Cultural, Contextual, And Individual Determinants Of Mental Health Service Utilization Among Latinx Emerging Adults, Kenia Carrera Diaz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Despite being at an increased risk of experiencing mental health problems, Latinx emerging adults underutilize professional psychological services compared to other ethnic/racial groups. It is important for researchers to understand this mental health disparity to improve Latinx emerging adults’ use of quality mental health services (MHS). The current project investigated factors that might influence Latinx emerging adult’s use of MHS through two separate studies. In the first study, I systematically reviewed research published in the past decade that examined predictors of MHS use among Latinx emerging adults. A total of 9 studies were found and included in this review. This …

Effects Of Imu Sensor Location And Number On The Validity Of Vertical Acceleration Time-Series Data In Countermovement Jumping, Dianne Althouse

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Many devices are available for measuring the height of a CMJ. An inertial measurement unit (IMU) measures linear acceleration, orientation, and angular velocity. As an alternative to using IMU estimates of flight time, CMJ height could be estimated by integrating the IMU time-series signal for vertical acceleration to derive CMJ take-off velocity in order to track whole-body center of mass (WBCoM) movement, yet this approach would require valid IMU acceleration data. Thus, the purpose of this study was to quantify the effects of IMU sensor location and number on the validity of vertical acceleration estimation in CMJ. Thirty young adults …

Association Between Visuomotor Skills And The Effects Of Stroboscopic Vision On Depth Jump Performance, Riley Welch

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The reactive strength index (RSI) is a popularized method of evaluating depth jump performance. Performance in anticipation of ground impact is influenced by the proprioceptive, vestibular, and visuomotor systems through multisensory integration. The contribution of vision to depth jump performance has been studied through use of stroboscopic goggles, but no study has evaluated which visuomotor skills may be a predictor for DJ performance. The purpose of this investigation was to evaluate the association between visuomotor skills and the effects of stroboscopic vision on DJ performance. Participants consisted of 9 female and 13 male college aged adults. DJ performance was evaluated …

Organizational Culture And Communication Competence Workshop: Masters Plan B, Travis Bergon

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This project began as an attempt to understand how events, such as the “Great Resignation” (i.e., an unprecedented mass exit of employees from the U.S. workforce), have impacted the way in which organizations are attempting to mitigate employee turnover. In addition, this project examined what role managers might play in promoting a positive organizational culture. A review of literature identified Schein’s (1990) model of organizational culture and Spitzberg and Cupach’s (1984) conceptualization of communication competence as useful frameworks for helping managers understand and promote positive organizational culture and employee mental health and well-being. In addition, the review of literature pointed …

Contributions Of Vision To The Neuromotor Control And Biomechanics Of Depth Jumping, Kenneth Harrison

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

PURPOSE: To investigate the role of vision during depth jump movements and further explore effects of stroboscopic goggles on the motor control of landing. METHODS: Ground reaction force (GRF), rate of force development (RFD), and lower limb surface electromyography measurements were collected on 20 participants (11 male 9 female) across 6 trials of depth jumping (0.51 m) in each of two visual conditions (full vision vs stroboscopic vision). Root-mean-square was estimated from EMG signals that were reduced to specific time-bins (150ms pre touchdown, 30-60ms, 60-85 ms, and 85-120 ms post touchdown). Main effects of and interactions between visual condition and …

Medicaid Expansion: Changes In Individual Health Outcomes, Julie Norman

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Affordable Care Act is one of the biggest changes in the American healthcare system in the 21st century. One element of the ACA is medicaid expansion, which opened up federal funding for states to cover any individual earning below 138% of the federal poverty line. 21 states expanded medicaid in 2014 while 12 haven’t expanded. This paper utilizes the disparity for a natural experiment to determine the efficacy of the program. Outcome variables of interest include measurements of individual health, health access and utilization, and premature death rates. The results indicate positive, but small improvements due to the policy, …

Management Of Garlic Mustard (Alliaria Petiolata), Sahara Mustard (Brassica Tournefortii), And Elongated Mustard (Brassica Elongata) In Utah, Natalie Layne Fronk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The invasive mustard species Sahara mustard (Brassica tournefortii), garlic mustard (Alliaria petiolata) and elongated mustard (Brassica elongata) negatively impact a variety of ecological systems across the state of Utah. The distribution of these species in Utah is relatively limited at the current time. If prompt action is taken, it may be possible to contain and manage these species before irreparable ecological and agricultural damage occurs. For this reason, all three mustards are listed by the State of Utah as weeds of high priority for management.

This project tested multiple strategies to determine effective species-specific …

The Association Of Military Sexual Harassment/Assault With Suicidal Ideation, Plans, Attempts, And Mortality Among Service Members And Veterans: A Meta-Analysis And Research Study, Whitney S. Livingston

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rates of death by suicide and sexual harassment/assault that occurs during military service (MSH/A) are higher among service members/veterans than rates of suicide and sexual violence among civilians. Suicide risk includes thoughts and attempts, and research examining the strength of the relationship between suicide risk and sexual violence across past studies that examined this association are limited to civilians. Moreover, current theories hypothesizing which factors are related to suicide risk do not adequately predict suicide among service members and veterans, and do not account for factors such as MSH/A. This two-study dissertation first calculated the magnitude of the relationship between …

Dairy Breed, Grass-Birdsfoot Trefoil Mixture, And Pasture Nutrition Effects On Intake, Feed Efficiency, And Grazing Adaptation, Michael Greenland

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dairy cattle have lower dry matter intake (DMI) on pastures thus leading to less weight gain and milk production than feedlot cows. This study was conducted to determine whether different dairy breeds are better adapted to lower or higher quality pastures as measured in DMI and feed efficiency. The eight treatments consisted of Jersey, Holstein, Holstein-Jersey crossbreds, and 3-breed crossbreds (Montbéliarde-Swedish Red-Holstein) heifers on grass monocultures and grass-BFT mixtures. We observed greater DMI on grass-BFT mixtures. Among breeds, Holstein had the greatest DMI, then the two crossbreds, and Jersey had the least. Feed efficiency was most favorable for Jersey, less …

Who Is More Likely To Be Delinquent In Their Mortgage Payments Among Homeowners? The Role Of Financial Literacy, Ellie Donne Hansen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Homeownership is a way for families to build wealth and marks status attainment. Despite the many benefits of homeownership, homeowners who are delinquent on their mortgages lose the effective means of wealth accumulation and may trigger the beginning of the foreclosure process. There is evidence that homeowners with appropriate levels of financial literacy have a lower likelihood of mortgage delinquency.

Using data from the 2018 National Financial Capability Study (NFCS), the main purpose of this study was to examine what factors are associated with mortgage delinquency among homeowners. This study also examined to what extent financial literacy plays a role …

Teaching Multicultural Psychology As A Cultural Competence Intervention: An Empirical Evaluation Of Course Components, Elizabeth Tish Hicks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous research has shown that a semester-long multicultural psychology course can effectively increase students’ cultural competence-related attitudes when students complete the class in-person and online. Cultural competence refers to the knowledge, awareness, and skills required to appreciate, recognize, and effectively work with members of other cultural groups. This dissertation examined several components of a multicultural psychology course: ethical grading, skill development, and intergroup contact. The first paper discussed techniques used to minimize grading bias and examined whether cultural competence shifts impacted grading. Students’ cultural competence scores did not relate to or predict their grades in the course, which supported the …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this explanatory sequential, mixed methods research study was to identify the perceptions of school resource officers (SROs) regarding high school students with disabilities and their preparedness to work with this population, as a result of their SRO training. This study involved a national quantitative survey of SROs working in public high schools, followed by one-on-one interviews from the same sample to allow for a deeper analysis of the survey results and develop a theory on how training impacts SRO preparedness and their perceptions of high school students with disabilities. The resulting theory ascertained that the presence of …

Collaborative Practices Of Rural Inclusive Postsecondary Education Program (Ipse) Directors, Elizabeth Susanne Goode Dimond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Inclusive postsecondary education programs (IPSE) for students with intellectual disabilities (ID) are relatively new, having their formal beginning in the Higher Education Opportunity Act (HEOA; P.L. 110-315) of 2008. These programs vary greatly and are found in urban, suburban, and rural areas of the United States. Those programs in rural areas face unique barriers and have unique strengths that affect how they collaborate and with whom they collaborate. The purpose of this qualitative phenomenological study is to describe the collaborative practices of rural IPSE program directors. This study gathered the lived experiences of rural IPSE program directors collaborating with agencies …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

What is mathematical modeling and how can inservice and pre-service teachers develop the skills and competencies necessary to increase confidence and interest in teaching relevant mathematical modeling lessons? Mathematical modeling is “the process of choosing and using appropriate mathematics and statistics to analyze empirical situations, to understand them better, and to improve decisions” (CSSM, 2010, p. 72). By providing students with an opportunity to engage in relevant mathematical modeling prompts, we provide them with transferable skills and knowledge. The aim of this paper will be to provide insight into the relevance of teaching mathematical modeling, provide resources for integrating modeling …

A Moderated Mediation Model Of Gender, Posttraumatic Cognitions, And Posttraumatic Stress Disorder Symptoms After Military Sexual Assault, Hallie S. Tannahill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Military sexual assault (MSA) is associated with the greatest risk for posttraumatic stress disorder (PTSD) and PTSD severity beyond other trauma types. Sexual revictimization further increases this risk and severity. However, not all who experience MSA revictimization develop PTSD. This suggests there may be a key mechanism that explains the association between MSA and PTSD. Posttraumatic cognitions (PTC), which include an overall domain and subdomains of self, world, and self-blame, may be one such mechanism between MSA and PTSD, although this link has not yet been examined in the context of MSA revictimization. Further, literature suggests that men and women …

Urban Soil Chemical And Nutrient Management Issues Facing Emerging Small Grower Enterprises In Utah, Frank E. Oliver

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Knowledge of both soil quality and contamination has become increasingly important with the growth of urban agriculture in Utah and the United States as whole. Land is also a common limiting factor in urban agriculture, so it is important to maximize yield and net returns. In order to meet these demands, three studies were conducted across key urban agriculture sites along the Wasatch Front: 1) an urban soil survey to assess soil contamination, 2) an urban soil survey to evaluate macronutrient and salinity levels, and 3) a nitrogen fertilizer management trial for dahlia (Dahlia pinnata), a cut flower …

Siblings Influence On Young Adults' Development: A Three-Study Dissertation, Jenna C. Dayley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As the longest lasting close relationship, often extending from birth until death, sibling relationships play an important role throughout the life course. To date, however, only limited work has examined the process by which siblings influence each other during young adulthood. Given that developmental differences between older and younger siblings diminish in young adulthood, it is possible that bidirectional (older-to-younger as well as younger-to-older) are more likely as compared to adolescence (in which top-down or older-to-younger influence has primarily been explored). It is further possible that processes of observational learning, including modeling, and sibling differentiation continue into young adulthood, shaping …

Predictors Of Special Education Inequity In Rural Rocky Mountain West Schools, Jac'lyn Bera

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Current research focusing on disproportionality and equity in schools focuses on the urban environment, resulting in a significant gap in our understanding of the challenges of rural schools. For rural, racially and ethnically minoritized (R/EM) students who have disabilities, this research is largely unavailable or minimal, and negatively affects our understanding of rural needs, barriers, and successes for this historically underserved population. There is even less research focused specifically on rural students in the Rocky Mountain West (RMW) region of the United States. Understanding these factors serves as a critical area of research, and is the focus of this study. …

Sustain Water Conservation Behaviors Using Nonparametric Ranking And Social Marketing, Mahmudur Rahman Aveek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Circulation of water use feedback and conservation messaging are strategies implemented to reduce water demand on a short-term (seasonal) basis. Often considered a less impactful strategy than other tactics such as price increments and usage restrictions, authorities mostly use feedback in informational campaigns with a focus to apprise users about their water use. Such conservation programs have had limited success that has been attributed to the fact that the information provided with the feedback campaigns was generic and did not motivate users enough to sustain their water-saving behaviors. However, the advent of disaggregation technologies that can provide appliance-wise water use …
