Waterpipe tobacco (WPT) smoking is a public health concern, particularly among youth and young adults. The global spread of WPT use has surged since the introduction of pre-packaged flavored and sweetened WPT, which is widely marketed as a safer tobacco alternative. Besides flavorants and sugars, WPT additives include humectants, which enhance the moisture and sweetness of WPT, act as solvents for flavors, and impart smoothness to the smoke, thus increasing appeal to users. In the United States (U.S.), unlike cigarette tobacco flavoring (with the exception of menthol), there is no FDA product standard or policy in place prohibiting sales of …

Water Throughout The Green Energy Transition: Hydrosocial Dimensions Of Coal, Natural Gas, And Lithium, Joshua J. Cousins, Alida Cantor, Bethani Turley

Geography Faculty Publications and Presentations

Energy transitions are reshaping hydrosocial relations. How they will be reshaped, however, depends on location and water's material relationship to other resources and industrial activities embedded within energy transitions. To highlight this, we focus on three different resources—coal, natural gas, and lithium—to signal how the water–energy nexus will be reworked in a transition away from fossil fuels. We examine the water–coal nexus as an example of a resource relationship that is transitioning out, or that is being moved away from in the green energy transition. Natural gas represents the “bridge fuel” used through the transition. Lithium illustrates a resource inside …

Working (Around/Within/Against) Prior Appropriation: Diverse Hydrosocial Practices To Secure Water For Rivers, Alida Cantor, Jillian Farley, Thien-Kim Bui, Zachary Boyce

Geography Faculty Publications and Presentations

Water scarcity in the Western US, through the lens of political ecology, can be understood as inextricably shaped by power dynamics, governance structures, and legal practices of resource allocation. Water allocation in the region is determined largely by the legal doctrine of Prior Appropriation, the 'first in time, first in right' principle. However, prior appropriation is fundamentally based in anthropocentric and settler colonial assumptions, and in light of drought, climate change, and shifting social and environmental values, the system has been critiqued as inadequate to meet contemporary water challenges. Despite challenging historical legacies, water managers in the Western US are …

The Integration Of Social Work Values And Principles In Police Work, Dasha Rhodes, Taylor Geyton, Jam Ost

School of Social Work Faculty Publications and Presentations

Persisting social inequities and injustices were spotlighted in the United States in 2020 after the murders of Breonna Taylor and George Floyd. A particular focus on the interactions of police officers and non-violent community members rallied a call to reallocate funds to social services better equipped to handle such situations, aptly named #defundthepolice. Many called for the need and placement of social workers in police agencies to curtail the negative interactions witnessed between police officers and communities of color, specifically with Black Americans. Across the nation, social workers are not always employed or readily available in police organizations. Therefore, instilling …

Synthesis And Computational Studies Of Α- And Δ-Substituted Macrocyclic Europium And Ytterbium Complexes, Delainey Amara Winder

Dissertations and Theses

The uses of macrocyclic lanthanide complexes are vast, with many targeted MRI contrast agents at the forefront of the field. Many of these are ParaCEST agents, which require exchangeable protons accessible on the macrocycle and the slow exchange of coordinated water molecules. The substitution at both the α- and δ-carbon on the amide pendant arm of these macrocyclic lanthanide complexes can lock bulky groups on the δ-carbon to a pseudo-axial position. When the α- and δ-carbons have the same chirality, the bulky group will be pseudo-equatorial, and when the chirality is opposed, the bulky group will be pseudo-axial. By performing …

Predation Of Appendicularians On Prochlorococcus, Carey Sweeney

Dissertations and Theses

Prochlorococcus is the most abundant photosynthetic cell on Earth. This picocyanobacterium is critical to primary productivity and biogeochemical cycles of the open ocean. While abiotic environmental factors that influence Prochlorococcus are relatively well-understood, biotic controls are less well known. Appendicularians are ubiquitous gelatinous zooplankton that feed on marine microorganisms including Prochlorococcus. However, the details of this feeding interaction are extremely understudied relative to its potential importance. In this study, I characterized the relationship between appendicularians and Prochlorococcus with laboratory experiments. I showed that feeding on Prochlorococcus changes with the life stage of the appendicularians and concentration of prey. I …

These public tip lines could increase investigations where the public is being made aware of the investigation, increasing the amount of information being brought forward. Research focuses on how tips reporting is similar to eyewitnesses in that individuals recall information. The literature illustrates how the media can influence the tips. The study is an exploratory content analysis looking at potential themes or patterns that emerged from analyzing the tips and patterns of the tip line and media files related to an …

Unbalanced Or Absent: Assessing Indigenous Representation In Interpretive Materials At Government Administered Heritage Sites In Cascadia And Hawai‘I, Leah Marie Rosenkranz, Jeremy Spoon, Douglas Deur

Anthropology Faculty Publications and Presentations

Unbalanced or absent Indigenous representation in interpretive materials at government administered heritage sites in settler colonial contexts can create contention and perpetuate a misinformed or one-dimensional visitor experience and historical narrative. This research therefore examines representation in interpretive materials accessible in 2019 at heritage sites with Indigenous ancestral connections in settler-colonial contexts. This study uses 10 U.S. case study heritage sites and two supplementary sites in Washington, Idaho, and Hawai‘i. Researchers utilized participant observation and systematic photography during two 2019 research phases to document interpretive materials. Quantification generated 731 analytic units which were subsequently assessed for the presence of inductively …

"We're Going To Tear Up The Caldera So We Can Have An Electric Car": Competing Perceptions And Spatial Dimensions Of Open-Pit Lithium Mining In The Mcdermitt Caldera, Oregon, Elizabeth Bartholomew

Dissertations and Theses

As the world attempts to pivot away from fossil fuels and other greenhouse gas-emitting activities that fuel climate change, the proposed technological solutions all require raw materials, resources, and land; each of which have their own logistical and political dimensions. Lithium, a federally recognized critical mineral that is considered a crucial element in modern battery production, plays a vital role in decarbonizing efforts. Under the banners of national security, resource independence, and carbon mitigation goals, the United States has incentivized domestic lithium extraction, expediting exploration throughout the American West. The McDermitt Caldera, spanning from southeastern Oregon into northern Nevada, is …

Exploring The Social Processes Influencing The Well-Being And Social Integration Of Systemically Marginalized Students In Higher Education: A Mixed-Methods Approach, Zeinab Abbas Hachem

Dissertations and Theses

Comprising two manuscripts, this dissertation employs a mixed-methods approach to comprehensively examine the intrapersonal and interpersonal processes influencing the socioemotional well-being and social integration of systemically marginalized students. The first manuscript quantitatively explored the relationship between ethnic identity commitment and indices of well-being, the mediating role of social relationships, and the moderating roles of gender and immigrant generation status among Latinx college students (N = 707). Results suggested that ethnic identity commitment was positively associated with socioemotional well-being. Although both types of relationships were significant mediators on their own, maternal (vs. peer) relationship quality was the stronger mediational influence. Furthermore, …

Crossover Of Supervisors' Perceptions Of Co-Worker Support To Employees' Well-Being, Shalene Joyce Allen

Dissertations and Theses

This study expands scholarly understanding of the positive impact of supervisors' perceptions of support on employee work-family and well-being experiences. Specifically, this study examines the role of resource-based positive crossover from supervisors' perceptions of co-worker support behavior to their employees. The current research draws on Systems Theory to understand the context, Conservation of Resources Theory to understand the type of resource purported to position individual resource gains, and crossover-spillover theory to understand the process through which resources crossover from supervisor to employee. Based on prior theory, this dissertation investigates a positive crossover effect of supervisors' perceptions of co-worker support at …

Openings And Closings In Human-Human Versus Human-Spoken Dialogue System Conversations, Judit Dombi, Tetyana Sydorenko, Veronika Timpe-Laughlin

Applied Linguistics Faculty Publications and Presentations

Although conversation openings and closings are ritualized speech acts (House & Kádár, 2023), they do require interactional work (Schegloff, 1986). Thus, they are important elements of interactional competence (Roever, 2022) and have been studied extensively in L2 interactions, including various types of technology-mediated communication contexts (e.g., Abe & Roever, 2019; 2020). However, to our knowledge, no research on openings and closings has been conducted with newer technologies such as spoken dialogue systems (SDS). To address this gap, this study compares conversation openings and closings across two modalities: a role-play with a human interlocutor versus with a fully automated agent. We …

Prosodic Analysis Of Wh-Indeterminate Questions In L2 Korean, Jung In Lee

Dissertations and Theses

Wh-indeterminate questions in Korean are potentially ambiguous due to the limited use of morpho-syntactic markers. When an explicit morpheme indicating the question type is not used, the disambiguation of the question relies, primarily, on prosodic cues. Drawing from previous studies of L1 Korean, this study examines the production and perception of intonation patterns of English L1 learners of Korean for wh- and yes-no questions in Korean. That examination allows speculation on potential L1 influence in the learners' production. Five English L1 learners of Korean who received formal instruction in Korean at a U.S. university completed a production and perception test …
