Outdoor recreation within Utah is managed and provided through a patchwork of federal and state agencies as well as county and municipal governments. Each of these entities manages outdoor recreation following different mandates and internal objectives. Rarely has there been an opportunity for representatives from federal, state, county, and local governments to sit down, discuss the long-standing and emerging challenges they face, and collectively develop ideas about how to work towards less-disparate and more aligned outdoor recreation management systems. In late 2022 and early 2023, we convened hundreds of land managers, outdoor recreation and tourism professionals, and elected officials across …

Navigating Cultural Identity In The Classroom, Caroline V. Phillips

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

As of 2016, ~25% of children in the United States are the children of immigrants (Nibbs & Brettell). Many of these youths struggle with the feeling that they belong neither to their parents’ cultural community nor to the locality in which they have been raised (Brockett, 2018). Furthermore, little academic research exists wherein these students share their experiences and engage in the processes of meaning making. This knowledge is essential for multicultural scholars and also for the (overwhelmingly white) population of K-6 teachers who help these youth construct personal identities. This project accomplishes the following:

1. I interview second-generation immigrants …


A Case For Educational Communication On Sustainable Stormwater Management Sites Using Interpretive Methods: Applications For Utah State University, Lilian Taft Aug 2023

A Case For Educational Communication On Sustainable Stormwater Management Sites Using Interpretive Methods: Applications For Utah State University, Lilian Taft

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

Humans are increasingly urbanizing landscapes, lowering the land’s ability to infiltrate stormwater, increasing surface water runoff. This, combined with decreasing water availability in the Intermountain West, produces the issue of sustainable stormwater management. Professionals are moving toward green stormwater infrastructure (GSI), but public is often not aware of stormwater’s impacts on natural environments or what the purpose of GSI is. Stormwater management design techniques are evolving to use visible, sustainable methods celebrating stormwater, rather than treating the valuable resource as a disposable nuisance, channeling it underground and out of sight. Artful Rainwater Design (ARD), a technique coined by Stuart Echols …

Reaction Time Under Limited Vision With Cognitive Challenge In Individuals With Anterior Cruciate Ligament Reconstruction, Hsuan Bonny Lu

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

The anterior cruciate ligament (ACL) rupture is a common sports injury. ACL reconstruction (ACLR) is a necessary treatment for individuals to return to competitive sports. However, a high rate of secondary injury occurs when individuals return to sport. Past research has shown that ACLR impairs physical performance, including reduction of force generate against the floor under the injured leg, changes in the gait pattern, and a loss of knee stability. While structural changes following ACL injury can leave the knee joint less stable, neurophysiological changes following ACL injury represent one potentially important mechanism underlying the performance deficits. Healthy individuals rely …

#Bodypositivity Or #Bodypolitics?: A Rhetorical Analysis Of The Body Positivity Myth Formed By Narratives Of Political Myth, Sydney Berenyi Lasike

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Body Positivity movement is well-known for advocating for the acceptance of all body types—including size, shape, color, and ability. Images online in support of the movement often showcase stretch marks, cellulite, and other “unattractive” bodily features to protest against the thin-ideal and strict standards of beauty placed upon women. Despite the goal to inspire self-love and celebration of all bodies, the hashtag #BodyPositivity has been taken-over by white, female influencers who have the idolized, female body. They contradict the original message of the movement through their posts on Instagram that centralize white feminine features and thin, Eurocentric bodies. This …

Opening The Black Box: Soil Microbial Communities In Field-Based Plant-Soil Feedback Experiments, Julia Kate Aaronson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plant-soil feedback is a process through which plants modify the properties of their associated soils, affecting their growth. PSF can play a key role in regulating plant growth and communities including altering plant invasion, rarity, and abundance. However, our understanding of the soil organisms that drive these plant growth responses is limited. Most studies treat soils as a ‘black box’ and do little to reveal which specific microbes or microbial communities may be responsible. This chapter examines two recent large PSF field experiments conducted in Minnesota, USA, and Jena, Germany. These experiments revealed that plants altered their soils, changing subsequent …
