"I'M Clean And Sober, But Not Necessarily Free": Perceptions Of Buprenorphine Among Patients In Long-Term Treatment, Jessica J. Wyse, Travis I. Lovejoy, Adam J. Gordon, Katherine Mackey, Anders Herreid-O'Neill, Benjamin J. Morasco

OHSU-PSU School of Public Health Faculty Publications and Presentations

Patients receiving buprenorphine for the treatment of opioid use disorder (OUD) experience a roughly 50% reduction in mortality risk relative to those not receiving medication. Longer periods of treatment are also associated with improved clinical outcomes. Despite this, patients often express desires to discontinue treatment and some view taper as treatment success. Little is known about the beliefs and medication perspectives of patients engaged in long-term buprenorphine treatment that may underlie motivations to discontinue.

The Use And Influence Of Health Indicators In Municipal Transportation Plans, Kelly Christine Rodgers

Dissertations and Theses

Transportation is an important social determinant of health that shapes the places where people "live, learn, work, and play" to the extent that an individual's zip code better predicts their health than their genetic code. Researchers and practitioners have called for the use of health indicators in transportation as one way to integrate public health concerns into transportation. The underlying hope is that new organizational routines, such as measuring and tracking indicators, can translate policy goals into policy practice. However, it is unclear how indicators are used and what impact they have on policy--the creation or modification of policies and …

Exploring The Plausibility Of Human Ecosystem Disruption Being The Cause For Increased Viral Prevalence, Andrew Ventura

University Honors Theses

Viral diseases and their prevalence--including both the number of cases and the appearance of new viruses--has increased in the last century, and these diseases have become an increasing threat to human health and well-being. The influenza and COVID-19 pandemics served both as introductions and reminders respectively to the power these viruses have to destroy and disrupt human life. As such, it intimates a necessity to investigate possible causes for the increase in these deadly diseases. Among these plausible causes is the dilution effect hypothesis, which states that decreasing the biodiversity of an ecosystem increases a pathogen's ability to infect, both …

The Networked Nitrous Node: A Low-Power Field-Deployable Cots-Based N2o Gas Sensor Platform, Ronaldo Leon, Wenyu Bi, Eyal Eynis, Travis Johnson, Wei Yan, David C. Burnett, John M. Acken

Electrical and Computer Engineering Faculty Publications and Presentations

We present a wireless nitrous oxide (N 2 O) gas sensor system consisting of a commercial high-current infrared N 2 O sensor wrapped in a “smart” sensor framework to make it suitable for battery-powered deployment. This framework consists of wireless mesh networking, data storage, additional environmental sensors, and a gas sensor power control circuit managed by a central microcontroller. The N 2 O sensor is the first order consumer of power and sampling N 2 O at approximately ten minute intervals yields an estimated system lifetime of 63 days when using four 18650 Li-ion batteries. The node stores data locally …

A Pwm Method For Reducing Dv/Dt And Switching Losses In Two-Stage Power Converters, Mahima Gupta, Abhijeet Prem

Electrical and Computer Engineering Faculty Publications and Presentations

Today's semiconductor devices are accompanied by high switching frequencies (> kilo-hertz) and small transition times (< micro-seconds). Such fast transition times are accompanied by undesirable effects such as voltage overshoots at the load terminals, ground leakage currents, wide-band electromagnetic noise, etc. With the advent of wide band-gap devices, several applications are moving towards higher switching frequency operation with at-least an order of magnitude reduction in transition times. While these characteristics are considered necessary to break the next-generation barriers in power density, efficiency and applicability, the undesirable effects due to faster transitions are expected to present obstacles. This work proposes a PWM approach to modify the shape of the switching voltages to overcome the disadvantages of the fast transition times without any increase in switching losses. In fact, several of the switching transitions feature ZVS operation, resulting in reduced switching losses. The paper discusses the analytical details of the approach using a simple DC-DC boost-buck converter and extends it to a DC to three-phase AC converter using the principles of space vector modulation. The paper presents detailed simulation and comparative results in terms of voltage over-shoots over long cables, loss calculations and electromagnetic noise. Results from a laboratory-scale working prototype confirm the benefits of the proposed approach in terms of EMI and loss reduction.

A Novel Deep Learning, Camera, And Sensorbased System For Enforcing Hand Hygiene Compliance In Healthcare Facilities, Samyak Shrimali, Christof Teuscher

Electrical and Computer Engineering Faculty Publications and Presentations

Hospital-acquired infections are a major cause of death worldwide, and poor hand hygiene compliance is a primary reason for their spread. This paper proposes an artificial intelligence, microcontroller, and sensor-based system that monitors and improves staff hand hygiene compliance at various critical points in a hospital. The system uses a Convolutional Neural Network (CNN) to detect and track if staff have followed the WHO hand rub/hand wash guidelines at alcohol dispensers, hospital sinks, and patient beds. The system also uses RFID tags, vibration motors, LEDs, and a central server to identify staff, alert them of their cleaning requirements, monitor their …

Madame Justice Will Save Our Democracy: Gender Bias And Perceptions Of The High Court In Transitional Regimes, Christopher Shortell, Melody E. Valdini

Political Science Faculty Publications and Presentations

While existing literature has established that women leaders are stereotyped as more likely to uphold the norms of democracy, the power of this effect in the non-democratic context is not established. We address this gap and argue that the context of regime transition cultivates a unique dynamic in which the stereotypes associated with women justices become especially valuable to both citizens and the state. However, we argue that this perception of women contributing to the health of democracy is not constant across all citizens equally; instead, those people with high levels of hostile bias against women are more likely to …

This research involved interviewing zero waste businesses and consultants and makers of plastic alternatives in India to understand their experiences with plastic reduction strategies. The key stakeholder interviews reveal key insights for moving forward …

Expanding On The Solutions To Reduce Neonatal Intensive Care Unit Morbidity And Mortality For Extremely Premature Infants—Looking Out The Hospital Window And Into The Neighborhoods, Christina Jäderholm, Lynne C. Messer

OHSU-PSU School of Public Health Faculty Publications and Presentations

The study from Sullivan et al1 is a valuable contribution to the literature that aims to improve health equity among very preterm infants (and their families). It is to be lauded for its attention to nonclinical factors such as area-level deprivation and racial disparities. By examining communitylevel factors such as area deprivation, this study engages both the medical and public health communities and places infant outcomes directly within the context of housing policy and lack of neighborhood investment. However, it is important that we articulate the connections between area deprivation and adverse outcomes for very preterm infants to even conceive …

Additionally, we sought to test the extent to which maternal social group membership attenuated the mediating effect of maternal depression on child mental health.

Methods

Data come from a population-based cohort of families living in the Nyakabare Parish, a rural district in southwestern Uganda. Between 2016 and 2018, mothers completed surveys about childhood adversity, depressive symptoms, social group membership, and their children's mental health. …

Vanishing Flies And The Lady Entomologist, Catherine Mcneur

History Faculty Publications and Presentations

The flies began emerging from the wheat around dusk, giving Margaretta Hare Morris little more than half an hour to observe the tiny, delicate creatures as they flitted from stalk to stalk. Requiring a magnifying glass to see them in any detail, Morris had first observed the flies as flaxseed-like pupa sleepily clinging to the young wheat plants in her neighbour’s field a few days prior, but now that they had fully transformed, there were too many and they were too quick to count. The swarms hovered over the wheat field, laying their eggs in the grain to secure a …

A New Frontier For Fat: Dietary Palmitic Acid Induces Innate Immune Memory, Amy L. Seufert, Brooke A. Napier

Biology Faculty Publications and Presentations

Dietary saturated fats have recently been appreciated for their ability to modify innate immune cell function, including monocytes, macrophages, and neutrophils. Many dietary saturated fatty acids (SFAs) embark on a unique pathway through the lymphatics following digestion, and this makes them intriguing candidates for inflammatory regulation during homeostasis and disease. Specifically, palmitic acid (PA) and diets enriched in PA have recently been implicated in driving innate immune memory in mice. PA has been shown to induce long-lasting hyper-inflammatory capacity against secondary microbial stimuli in vitro and in vivo, and PA-enriched diets alter the developmental trajectory of stem cell progenitors in …

Direct Spectroscopic Observation Of Cross-Plane Heat Transfer In A Two-Dimensional Van Der Waals Heterostructure, Du Chen, Matthieu Fortin-Deschênes, Yuchen Lou, Huiju Lee, Kenji Watanabe, Takaaki Taniguchi, Fengnian Xia, Peijun Guo, Multiple Additional Authors

Mechanical and Materials Engineering Faculty Publications and Presentations

Two-dimensional (2D) transition metal chalcogenides (TMDs) have drawn significant attention in recent years due to their extraordinary optical and electronic properties. As heat transfer plays an important role in device performance, various methods such as optothermal Raman spectroscopy and time-domain thermoreflectance have been developed to measure the thermal conductivity and interfacial thermal conductance in 2D van der Waals (vdW) heterostructures. Here, we employ the vibrational-pump-visible-probe (VPVP) spectroscopy to directly visualize the heat transfer process in a heterostructure of multilayer h-BN and monolayer WS2. Following an impulsive vibrational excitation of h-BN in the mid-infrared, we probe the heat transfer …

Effectiveness Of Worksite Wellness Programs Based On Physical Activity To Improve Workers’ Health And Productivity: A Systematic Review, Maria Marin‑Farrona, Bradley Wipfli, Saurabh S. Thosar, Enrique Colino, Jorge Garcia‑Unanu, Multiple Additional Authors

Psychology Faculty Publications and Presentations

Background

Although the scientific literature has previously described the impact of worksite programs based on physical activity (WPPAs) on employees’ productivity and health in different contexts, the effect of these programs has not been analyzed based on the characteristics or modalities of physical activity (PA) performed (e.g., aerobic exercise, strength training, flexibility). In addition, studies on WPPAs usually report health and productivity outcomes separately, not integrated into a single study. Knowing the health and economic-related impacts of a WPPAs could provide useful information for stakeholders and policy development.

Objective

The purpose of this review was as follows: (1) to analyze …

Flow Development And Entrainment In Turbulent Particle-Laden Jets, Laura K. Shannon, Bianca Viggiano, Raúl Bayoán Cal, L. G. Mastin, Alexa R. Van Eaton, Stephen Solovitz

Mechanical and Materials Engineering Faculty Publications and Presentations

Explosive eruptions expel volcanic gases and particles at high pressures and velocities. Within this multiphase fluid, small ash particles affect the flow dynamics, impacting mixing, entrainment, turbulence, and aggregation. To examine the role of turbulent particle behavior, we conducted an analogue experiment using a particle-laden jet. We used compressed air as the carrier fluid, considering turbulent conditions at Reynolds numbers from approximately 5,000 to 20,000. Two different particles were examined: 14-μm diameter solid nickel spheres and 13-μm diameter hollow glass spheres. These resulted in Stokes numbers between 1 and 35 based on the convective scale. The particle mass percentage in …

Global Water Level Variability Observed After The Hunga Tonga-Hunga Ha’Apai Volcanic Tsunami Of 2022, Adam Thomas Devlin, David A. Jay, Stefan Talke, Jiayi Pan

Civil and Environmental Engineering Faculty Publications and Presentations

The eruption of the Hunga Tonga-Hunga Ha'apai volcano on 15 January 2022 provided a rare opportunity to understand global tsunami impacts of explosive volcanism and to evaluate future hazards, including dangers from “volcanic meteotsunamis” (VMTs) induced by the atmospheric shock waves that followed the eruption. The propagation of the volcanic and marine tsunamis was analyzed using globally distributed 1 min measurements of air pressure and water level (WL) (from both tide gauges and deep-water buoys). The marine tsunami propagated primarily throughout the Pacific, reaching nearly 2 m at some locations, though most Pacific locations recorded maximums lower than 1 m. …
