The Effect Of Seed Mix Density And Composition On Wetland Plant Community Assembly In The Great Salt Lake Watershed, Elana Feldman

All Graduate Theses and Dissertations, Fall 2023 to Present

Wetlands provide important ecosystem services to society but are in danger across the globe partly due to the spread of invasive species (species that harm humans, the environment, or the economy). One species, Phragmites australis, is a widespread invader across the country, including in the wetlands of the Great Salt Lake and Utah Lake. Phragmites australis spreads widely and quickly outcompetes native species. In places where P. australis has already been removed, seeding wetlands helps block P. australis from returning. Native plants’ ability to prevent invasive species from entering the community is affected by many factors, but two that …

Do Poor Countries Catch Up To Rich Countries? Structural Change In The World-Economy, 1816-1916, Jared Walker

All Graduate Theses and Dissertations, Fall 2023 to Present

Do poor countries catch up to rich countries? To answer that question, countries were divided into upper class (core), middle class (semi-periphery), and lower class (periphery) based on degree of industrialization as indicated by primary energy consumption data. Findings indicated twenty-three upward transitions and five downward transitions during the period examined. Asymmetrical upward mobility was understood in the context of geographic expansion of the system. This sufficiently increased the population of the lower class (periphery) to support larger populations in the middle class (semi-periphery) and upper class (core). Nevertheless, probability analysis indicated a stable system characterized by high levels of …

Field Flow Measurements For Pipe Installations With Non-Ideal Conditions, Jake Douglas

All Graduate Theses and Dissertations, Fall 2023 to Present

Accurate flow measurement data is necessary to effectively manage water resources. The purpose of this research is to investigate options to improve field flow measurement by investigating alternatives for calibrating flow meters installed in non-ideal piping. Typically, to accurately measure a flow rate using most types of flow meters, it is recommended that a straight section of pipe be installed immediately upstream and downstream of the flow meter to avoid flow fluctuations at the meter location. However, in many cases, flow disturbances upstream of the meter are unavoidable.

The performance of field flow measurements in non-ideal piping scenarios were studied …

Difference Between The Impact Of Active Social Media Use And Passive Social Media Use On Adolescent Mental Health: An Expanded Literature Review, Lydia Underwood

The Eleanor Mann School of Nursing Undergraduate Honors Theses

Background: With the first generation of adolescents being raised with seemingly unlimited access to social media, there is a clear need for research to determine the long-term mental health effects of social media use. Social media use can be categorized into two main categories — active use and passive use. Active use refers to a user posting content and engaging in the media they are viewing. Contrastingly, passive use refers to a user consuming social media content, without engaging in it in ways such as liking or commenting. The aim of this extended literature review was to answer the …

Barriers To Breastfeeding In Low Socioeconomic Populations, Nikki Goldberg, Paige Daws

The Eleanor Mann School of Nursing Undergraduate Honors Theses

This literature review assessed and determined common themes among vulnerable populations for the initiation and continuation of breastfeeding habits. The barriers identified were divided into four themes including: lack of support, inflexible employment environment, differences of breastfeeding norms and education, and financial burden. Interventions identified in this literature review were community support programs and the implementation of hospital programs and initiatives to encourage breastfeeding. The need for this research and discussion stems from the sub-optimal infant feeding practices that contribute to infant mortality rates (Gallegos et al., 2020).

Faculty, Staff and Students Publications

BACKGROUND: Single-pulse electrical stimulation (SPES) is an established technique used to map functional effective connectivity networks in treatment-refractory epilepsy patients undergoing intracranial-electroencephalography monitoring. While the connectivity path between stimulation and recording sites has been explored through the integration of structural connectivity, there are substantial gaps, such that new modeling approaches may advance our understanding of connectivity derived from SPES studies.

NEW METHOD: Using intracranial electrophysiology data recorded from a single patient undergoing stereo-electroencephalography (sEEG) evaluation, we employ an automated detection method to identify early response components, C1, from pulse-evoked potentials (PEPs) induced by SPES. C1 components were utilized for a …

Shocking Financed Emissions: The Effect Of Economic Volatility On The Portfolio Footprinting Of Financial Institutions, Ilmi Granoff, Tonya Lee

Sabin Center for Climate Change Law

Many financial institutions are now calculating and disclosing their financed emissions, a class of metrics enabling these institutions to calculate the greenhouse gas (GHG) emissions associated with investment and lending activities. These institutions have widely adopted the metric to estimate exposure to climate-related financial risk associated with GHG-emitting activities and to provide shareholders and investors a picture of how their financial activity impacts global climate change. Financed emissions metrics, despite widespread adoption, face two key methodological challenges: lack of comparability of outputs within and between portfolios, and vulnerability of calculations to portfolio volatility. Markets are naturally volatile, but the economic …
