Through a narrative inquiry methodology utilizing the theoretical paradigms of self-determination theory and relational autonomy, this study extended understanding of the factors that motivate persistence for women in certain STEM fields. While prior research focused on understanding the barriers to retention, this study sought to identify the factors motivating retention for women in certain STEM fields. The results of this study contribute to understanding the motivating factors that influence a woman’s persistence in STEM. The data gathered from …

Addressing The Importance Of Recruitment And Retention Of Black And Latinx Teachers: Strategies Designed To Diversify The Teacher Pipeline, Shavon Pittman

Dissertations

The United States student demographic has shifted significantly, with minorities, particularly Black and Latinx students, now constituting almost half. However, the diversity of the teaching profession, historically led by White females, lags behind, with Black and Latinx teachers comprising less than 30%. This lack of representation poses challenges for students without culturally similar educators. My research explores the impact of teacher diversity on Black and Latinx students' success, revealing positive outcomes. Yet, attracting and retaining minority teachers faces obstacles, including feelings of isolation and financial concerns. Recommendations include educational pathways, scholarships, mentoring programs, salary incentives, and professional learning communities to …

Indiana's Public Health Investment Holds Insights For Other States, Nir Menachemi, Lindsay Weaver, Virginia Caine, D Shane Hatchett, Kristina Box, Paul K. Halverson

OHSU-PSU School of Public Health Faculty Publications and Presentations

Indiana has a business-friendly environment, but historical underinvestment in public health has yielded poor health outcomes. In 2023, when trust in governmental public health was strained nationwide, Indiana increased public health spending by 1,500 percent. In this article, we explain how Indiana achieved this unprecedented legislative victory for public health, describing the context, approach, and lessons learned. Specifically, an Indiana University report linking economic vitality and overall health sparked the creation of a governor's commission charged with exploring ways to address Indiana's shortcomings. Working with the Indiana Department of Health, the commission developed multisectoral coalitions and business and government partnerships, …

Reversal Of Propofol-Induced Depression Of The Hypoxic Ventilatory Response By Bk-Channel Blocker Ena-001: A Randomized Controlled Trial, Simone Jansen, Maarten Van Lemmen, Erik Olofsen, Laurence Moss, Joseph Pergolizzi, Thomas Miller, Robert Colucci, Monique Van Velzen, Philip Kremer, Albert Dahan, Rutger Van Der Schrier, Marieke Niesters

Department of Medicine Faculty Papers

BACKGROUND: The use of anesthetics may result in depression of the hypoxic ventilatory response. Since there are no receptor-specific antagonists for most anesthetics, there is the need for agnostic respiratory stimulants that increase respiratory drive irrespective of its cause. The authors tested whether ENA-001, an agnostic respiratory stimulant that blocks carotid body BK-channels, could restore the hypoxic ventilatory response during propofol infusion. They hypothesize that ENA-001 is able to fully restore the hypoxic ventilatory response.

METHODS: In this randomized, double-blind crossover trial, 14 male and female healthy volunteers were randomized to receive placebo and low- and high-dose ENA-001 on three …

Department of Medicine Faculty Papers

Aim: Use long-term follow-up data from the IMPERIAL study to determine whether drug-eluting polymer-based nitinol stent treatment can delay the time to repeat intervention for femoropopliteal artery disease and how such a delay may result in cost savings in a value-based episode of care. Patients & methods: The IMPERIAL randomized controlled trial was an international study of a paclitaxel-eluting polymer-coated stent (Eluvia, Boston Scientific, MA, USA) versus a polymer-free paclitaxel-coated stent (Zilver PTX, Cook Corporation, IN, USA) for treating lesions of the femoropopliteal arterial segment. Study patients (n = 465) had symptomatic lower limb ischemia. Safety and efficacy assessments were …

Development And External Validation Of The 'Global Surgical-Site Infection' (Glossi) Predictive Model In Adult Patients Undergoing Gastrointestinal Surgery, Viren P. Punja, Melanie K. Sion, Michael S. Weinstein

Department of Medicine Faculty Papers

Background: Identification of patients at high risk of surgical-site infections may allow surgeons to minimize associated morbidity. However, there are significant concerns regarding the methodological quality and transportability of models previously developed. The aim of this study was to develop a novel score to predict 30-day surgical-site infection risk after gastrointestinal surgery across a global context and externally validate against existing models. Methods: This was a secondary analysis of two prospective international cohort studies: GlobalSurg-1 (July-November 2014) and GlobalSurg-2 (January-July 2016). Consecutive adults undergoing gastrointestinal surgery were eligible. Model development was performed using GlobalSurg-2 data, with novel and previous scores …

Optimization Methods For Parameter Estimation In A Scalar Partial Differential Equation: Stochastic Variants, Yidan Yang

Theses

In this work, we present stochastic variants of an optimization method for the problem of recovering a spatially varying parameter in a scalar partial differential equation (PDE) from measurement(s) of the state variable. In many inverse problems associated with PDE models, the goal is to utilize observational measurements of the state variable in the estimation of the model parameter(s). In the problem being studied, the hydraulic conductivity of an aquifer (a function of location) is the parameter/coefficient to be recovered and the hydraulic (or piezometric) head is the quantity observed/measured. We discuss the choices of objective functional (such as output …

Models Of Rrna Templated Assembly Of The Nucleolus In The C. Elegans Embryo, Nishant Kodan

Theses

The nucleolus is a large membraneless organelle located in the nucleus of eukaryotic cells. It is a multicomponent structure primarily made of RNA and proteins and serves as the site of ribosome biogenesis. It has been extensively studied as a prototype of a membraneless organelle whose assembly is driven by phase separation, but factors affecting the dynamics of nucleolar assembly are not well understood. Experiments show that the size of the nucleolus scales with the size of the nucleus, which decreases through reductive divisions in the early C. elegans embryo. These observations are consistent with the idea that a finite …

Sustainable Energy Access And Irrigation Planning In Sub Saharan Africa, Fhazhil Wamalwa

Theses

Sub-Saharan Africa (SSA) is the least developed and most vulnerable region to climate change globally, with electricity access and irrigation rates at 45% and 5%, respectively. The region's high reliance on rain-fed farming results in significant yield gaps, increasing dependence on food imports and aid. Projected declines in rainfed agricultural productivity due to climate-induced rainfall variability, coupled with a rapid population growth rate of 2.8% per year, will likely exacerbate food insufficiency. SSA is largely rural, with an urbanization rate of 42%. Much of its population lives in sparsely populated settlements characterized by low electricity demand, which poses a significant …

Modeling The Reverberation Response Of The Broad Line Region In Active Galactic Nuclei, Sara A. Rosborough

Theses

The supermassive black holes (SMBHs) that reside at the centers of massive galaxies are observed as active galactic nuclei (AGN) when they are rapidly consuming matter from a surrounding accretion disk, which releases large amounts of electromagnetic radiation. Closely surrounding this engine are the dense gas clouds of the broad line region (BLR), which are photoionized by the continuum radiation emitted by the accretion disk. As these clouds are deep within the potential well of the SMBH, the gas emission lines (the broad emission lines; BELs) are Doppler-broadened by several 1,000 km/s. Measuring the size and velocity dispersion of the …

Turbulence: Full Issue Download

Quill & Scope

Turbulence is an essential part of the natural world. Opposing currents churn the deep waters of the ocean, strong winds clear the air of pollutants, and powerful storms drench the earth with life-sustaining water. Yet, when we humans find ourselves experiencing turbulence, our gut reaction is often to bear down and anchor ourselves. Perhaps you, like us, have found yourself closing your eyes and tightly grasping the armrests of your airplane seat as the wings rock, or trying to keep your eyes on the horizon to prevent seasickness from taking hold in choppy waters. Anchoring ourselves allows us to maintain …

Early Detection Of Structural Damage In Uhpfrc Structures Through The Combination Of Acoustic Emission And Ultrasonic Stress Wave Monitoring, Numa Bertola, Thomas Schumacher, Ernst Niederleithinger, Eugen Brühwiler

Civil and Environmental Engineering Faculty Publications and Presentations

Ultra-High-Performance Fiber-Reinforced Cementitious Composite (UHPFRC) offers several advantages compared to concrete, notably due to the strain hardening behavior under tensile actions. Structures made of this composite material are lightweight and highly durable, thanks to the UHPFRC waterproofing quality. Nonetheless, the tensile behavior leads to a different cracking pattern than conventional concrete and is not fully understood yet. This paper presents a combined approach using both passive ultrasonic (US) stress wave (or acoustic emission) and active US stress wave monitoring to localize and quantify damage progression in a full-scale UHPFRC beam during experimental load testing. The proposed monitoring approach involves 24 …

Matching The Scales Of Planning And Environmental Risk: An Evaluation Of Community Wildfire Protection Plans In The Western Us, Matthew Hamilton, Cody Evers, Max Nielsen-Pincus, Alan A. Ager

Environmental Science and Management Faculty Publications and Presentations

Theory predicts that effective environmental governance requires that the scales of management account for the scales of environmental processes. A good example is community wildfire protection planning. Plan boundaries that are too narrowly defined may miss sources of wildfire risk originating at larger geographic scales whereas boundaries that are too broadly defined dilute resources. Although the concept of scale (mis)matches is widely discussed in literature on risk mitigation as well as environmental governance more generally, rarely has the concept been rigorously quantified. We introduce methods to address this limitation, and we apply our approach to assess scale matching among Community …

An Index Of Biotic Integrity For Macroinvertebrate Stream Bioassessment Conducted By Community Scientists, Patrick M. Edwards, Daniel Bedell, Shannon Hubler, Chad A. Larson, Kate H. Macneale, Elisa Mickelson, Chris Prescott, Elinore Webb, Jo Wilhelm

Environmental Science and Management Faculty Publications and Presentations

Community science bioassessment has great potential to inform comprehensive stream management plans, but regional analytical tools are needed to evaluate macroinvertebrate data collected through community science programs. To this end, we modified a pre-existing professional index of biotic integrity (IBI) to create a community science IBI (CS-IBI), designed for stream macroinvertebrate data collected by community scientists with minimal training. We used data collected by both professional and community scientists to develop, calibrate, and validate the CS-IBI at 76 streamsites in the Puget Lowland andWillamette Valley ecoregions of the PacificNorthwest in theUnited States. Community science data were taxonomically coarser andmore variable …

Interpretable Learning In Multivariate Big Data Analysis For Network Monitoring, José Camacho, Katarzyna Wasielewska, Rasmus Bro, David Kotz

Dartmouth Scholarship

There is an increasing interest in the development of new data-driven models useful to assess the performance of communication networks. For many applications, like network monitoring and troubleshooting, a data model is of little use if it cannot be interpreted by a human operator. In this paper, we present an extension of the Multivariate Big Data Analysis (MBDA) methodology, a recently proposed interpretable data analysis tool. In this extension, we propose a solution to the automatic derivation of features, a cornerstone step for the application of MBDA when the amount of data is massive. The resulting network monitoring approach allows …

Development Of A Two-Photon Imaging System, Jesseca Hollenbaugh

University Honors Theses

The objective of this project was to convert a Sarastro 2000 confocal laser scanning microscope (CLSM) into a system capable of far-field two-photon excitation (TPE) imaging for the use of the PSU Biology department. TPE microscopy operates on the ability of fluorophores to accept two photons each with half the energy of a desired transition in a single quantum event via a virtual energy state and then emit a higher energy photon upon relaxation. This is preferable to single-photon excitation (SPE) imaging due to lower photon imaging, causing less damage to delicate biological samples, as well as the inherent localization …

Comparing Erwartung And Die Glückliche Hand Through The Female Gaze, Angela Tinio

University Honors Theses

During the early 20^th century, the rise of psychoanalysis impacted society by offering a revolutionary approach to the mind. This rise occurred due to the work of the work of Sigmund Freud (1856-1939), who believed many mental disorders were rooted in the subconscious. Psychoanalysis revolutionized how we approach the brain and offered a new perspective on patient treatment. Artists in the early 20^th century also explored and insisted on new ways to view society through art. Schoenberg and Freud were both pioneers in their field of work, and Freud even inspired Schoenberg's early atonal music. Freud may have …
