Heat Mapping Crime: A Data-Driven Approach To Policing In New York, Beruktawit Gebreamlak, Daniel Ochoa

altREU Projects

In the aftermath of the COVID-19 pandemic, New York City has seen a surge in criminal activities. In 2023, major crime continues to be higher compared to pre-pandemic levels. Although progress is being made to reduce the number of murders and robberies, law enforcement is continuing to struggle with increases in felony assaults and car thefts. Our project serves to benefit members of the community and law enforcement alike. We created a heat map, which is a visual representation of data that uses colors to represent different values. In the context of crime mapping, our heat map is used to …

Multidrug Resistance Of Escherichia Coli From Outpatient Uncomplicated Urinary Tract Infections In A Large United States Integrated Healthcare Organization, Katia J. Bruxvoort, Jennifer H. Ku, S. Bianca Salas, Cara D. Varley, Joan A. Casey, Eva Raphael, Sarah C. Robinson, Keeve E. Nachman, Bruno J. Lewin, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background

Urinary tract infections (UTIs) cause significant disease and economic burden. Uncomplicated UTIs (uUTIs) occur in otherwise healthy individuals without underlying structural abnormalities, with uropathogenic Escherichia coli (UPEC) accounting for 80% of cases. With recent transitions in healthcare toward virtual visits, data on multidrug resistance (MDR) (resistant to ≥3 antibiotic classes) by care setting are needed to inform empiric treatment decision making.

Methods

We evaluated UPEC resistance over time by care setting (in-person vs virtual), in adults who received outpatient care for uUTI at Kaiser Permanente Southern California between January 2016 and December 2021.

Results

We included 174 185 individuals …

Melanoma Literacy Among The General Population Of Three Western Us States, Sancy A. Leachman, Elizabeth Stoos, Brian Detweiler-Bedell, Jerusha B. Detweiler-Bedell, Adrienne Zell, Elizabeth Wenzel, Emile Latour, Jack T. Wiedrick, Jodi Lapidus, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Melanoma is a significant cause of cancer death, despite being detectable without specialized or invasive technologies. Understanding barriers to preventive behaviors such as skin self-examination (SSE) could help to define interventions for increasing the frequency of early detection. To determine melanoma knowledge and beliefs across three high-incidence US states, 15,000 surveys were sent to a population-representative sample. We aimed to assess (1) melanoma literacy (i.e., knowledge about melanoma risks, attitudes, and preventive behaviors) and (2) self-reported SSE and its association with melanoma literacy, self-efficacy, and belief in the benefits of SSE. Of 2326 respondents, only 21.2% provided responses indicating high …

Racial/Ethnic And Gender Inequities In The Sufficiency Of Paid Leave During The Covid‐19 Pandemic: Evidence From The Service Sector, Julia M. Goodman, Daniel Schneider

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Access to paid family and medical leave (PFML), including leave to care for a seriously ill loved one or recover from one's own serious illness, conveys health and economic benefits for workers and their families. However, without a national PFML policy, access to paid leave remains limited and unequal. Previous work documenting inequitable access by socioeconomic status and race/ethnicity primarily focuses on parental leave, measures theoretical access to paid leave rather than actual leave uptake, and lacks an accounting for why workers of color and women may have less access to PFML. We extend this literature by looking at …

A Graph Theory Approach For Public Transit Connectivity In New York City, Francisco Rodriguez, Jhosseline Zhunio

altREU Projects

Transit deserts are defined as not having access to rapid transit, such as train or bus services, within one mile of one’s residence. In New York City, boroughs outside the city’s center struggle with this the most, especially when limited bus services are only offered. Transit deserts bring the most impact for low-income and people of color (POC) communities, limiting their access to essentials such as job opportunities, healthcare, and food supplies. The Metropolitan Transportation Authority (MTA) has tried addressing this issue with experts in arcGIS, a Geographical Information System (GIS) software, resulting in the cutting down of essential bus …

A Content Analysis Of Social Media Discussions On Thc-Oacetate, Daniel J. Kruger, Amila Karahmet, Sydney M. Kaplan, Taylor Stacy, John Redfield, Vitush Agarwal, Mutaz Faqqouseh, Carlton Cb. Bone

Anthropology Faculty Publications and Presentations

Novel cannabinoids require systematic research to inform policies and practices. There is a growing interest in semi-synthetic cannabinoids by consumers, manufacturers, and regulators. However, there is a scarcity of research on these substances. Online discussion forums can provide guidance for research questions when current knowledge is scarce. The current project investigates the topics and issues covered in a social media forum devoted to THC-O-acetate (THCO), a semi-synthetic cannabinoid with rapidly rising popularity. Reddit comments posted on the THCO subreddit from June 2021 through November 2021 were coded for major and minor themes by a team of five coders and a …

A Study On The Gaseous Radionuclide Dispersion In The Highway Across Urban Blocks: Effects Of The Urban Morphology, Roadside Vegetation And Leakage Location, Rui Jia, Jianzhi Yang, Xiaowei Zhu, Fusuo Xu, Liping Wang

Mechanical and Materials Engineering Faculty Publications and Presentations

Spent fuel is a used nuclear waste that poses a great hazard to human body and the environment. In this work, the dispersion of gaseous radionuclides from the highway to downstream urban is simulated using CFD based on a hypothetical spent fuel transport accident, with focus on the effects of urban morphology, roadside vegetation and leakage location. The velocity field, TKE (turbulent kinetic energy) distribution and radionuclide concentration under different conditions are carefully explored. The results show that the dispersion of radionuclides is greatly influenced by the velocity field and TKE distribution. The health risk to the residents of sparse …

Exploring And Testing Wildfire Risk Decision-Making In The Face Of Deep Uncertainty, Bart R. Johnson, Alan A. Ager, Cody Evers, David Hulse, Max Nielsen-Pincus, John P. Bolte

Environmental Science and Management Faculty Publications and Presentations

We integrated a mechanistic wildfire simulation system with an agent-based landscape change model to investigate the feedbacks among climate change, population growth, development, landowner decision-making, vegetative succession, and wildfire. Our goal was to develop an adaptable simulation platform for anticipating risk-mitigation tradeoffs in a fire-prone wildland– urban interface (WUI) facing conditions outside the bounds of experience. We describe how five social and ecological system (SES) submodels interact over time and space to generate highly variable alternative futures even within the same scenario as stochastic elements in simulated wildfire, succession, and landowner decisions create large sets of unique, path-dependent futures for …

Wildfire Risk Governance From The Bottom Up: Linking Local Planning Processes In Fragmented Landscapes, Matthew Hamilton, Max Nielsen-Pincus, Cody Evers

Environmental Science and Management Faculty Publications and Presentations

The growing scale of natural hazards highlights the need for models of governance capable of addressing risk across administrative boundaries. However, risk governance systems are often fragmented, decentralized, and sustained by informal linkages among local-level risk mitigation planning processes. Improving resilience to the effects of environmental change requires a better understanding of factors that contribute to these linkages. Using data on the patterns of participation of 10,199 individual stakeholders in 837 community wildfire protection plans (CWPPs) within the western U.S., we document the emergence of a locally clustered but spatially extensive wildfire risk governance network. Our evaluation of factors that …

The Past, Present, And Future Of The Latino Paradox, Sheila Flores

University Honors Theses

The Latino/Hispanic paradox has left scholars and researchers puzzled as to how Latinos, despite facing socioeconomic challenges, show better health outcomes when compared to other racial/ethnic groups. The emergence of this phenomenon can be traced back to the 1980s/1990s when researchers first noticed Latinos in the United States having characteristics of lower mortality rates and improved health compared with non-Hispanic whites despite having a better socioeconomic status. Performing a literature review of scholars analyzing the past, present, and future of the Latino Paradox will thus allow for an understanding of its origin, current state, and the possible potential trajectories that …

Respecting Tribal Voices In The Development Of A Gestational Diabetes Risk Reduction Preconception Counseling Program For American Indian/Alaska Native Adolescent Females: A Qualitative Study, Kelly R. Moore, Sarah Stotz, Martha Ann Terry, Ellen Seely, Kelly Gonzales, Gale Marshall, Jay Nadeau, Aletha Akers, Yesenia Garcia-Reyes, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background American Indians and Alaska Natives (AI/AN) are disproportionately affected by adolescent obesity, adolescent pregnancy and gestational diabetes mellitus (GDM). GDM is associated with increased risk for perinatal death, obesity, and subsequent type 2 diabetes (T2D) for the offspring. Moreover, mothers with GDM are also at increased risk for T2D post-partum. Yet few lifestyle interventions exist to reduce GDM risk prior to pregnancy. We describe the process of adapting an existing validated preconception counseling intervention for AI/AN adolescent girls at-risk for GDM and their mothers. Perspectives and recommendations were gathered from a diverse array of stakeholders to assure the new …

Musculoskeletal Pain, A Possible Indicator Of Central Sensitization, Is Positively Associated With Lower Urinary Tract Symptom Progression In Community-Dwelling Older Men, Angela Senders, Scott Bauer, Yiyi Chen, Barry Oken, Howard A. Fink, Nancy E. Lane, Kamran P. Sajadi, Lynn M. Marshall

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background

Musculoskeletal pain, a possible marker of central sensitization, is associated with higher prevalence of lower urinary tract symptoms (LUTS) among older men. We investigated whether musculoskeletal pain is associated with LUTS progression.

Methods

Participants were 5 569 men age ≥65 years enrolled in the prospective, multicenter Osteoporotic Fractures in Men (MrOS) Study. Self-reported musculoskeletal pain within 12 months before baseline was categorized as any pain and multilocation pain. Pain interference within 4 weeks of baseline was assessed with the SF-12 questionnaire. LUTS were assessed repeatedly with the American Urological Association Symptom Index (AUA-SI). Men with severe LUTS at baseline …

Modeling And Validating Temporal Rules With Semantic Petri Net For Digital Twins, Han Liu, Xiaoyu Song, Ge Gao, Hehua Zhang, Yu-Shen Liu, Ming Gu

Electrical and Computer Engineering Faculty Publications and Presentations

Semantic rule checking on RDFS/OWL data has been widely used in the construction industry. At present, semantic rule checking is mainly performed on static models. There are still challenges in integrating temporal models and semantic models for combined rule checking. In this paper, Semantic Petri-Net (SPN) is proposed as a novel temporal modeling and validating method, which implements the states and transitions of the Colored Petri-Net directly based on RDFS and SPARQL, and realizes two-way sharing of knowledge between domain semantic webs and temporal models in the runtime. Several cases are provided to demonstrate the possible applications in digital twins …

Valuing Ecosystem Services From Restoring Ancient Irrigation Systems: An Application Comparing Labor Vs. Monetary Payments For Choice Experiments, Sahan Dissanayake, Shamen Vidanage

Economics Faculty Publications and Presentations

The use of stated preference methods in developing countries is growing with the increasing concern about the environment as economies develop. At the same time using monetary payment vehicles and estimating a Willingnessto Pay (WTP) can be problematic in rural or low incomes areas in developing countries. Many respondents in these areas regularly engage in barter and paying with labor and do not use monetary payments for all transactions. This distinction from urban areas with a monetary economy and with most settings in developed countries can impact results from valuation studies as the WTP elicited from rural and low-income areas …

Use Of Chinese Herbal Medicine Was Related To Lower Risk Of Osteoporotic Fracture In Sarcopenia Patients: Evidence From Population-Based Health Claims, Wei-Jen Chen, Hanoch Livneh, Hsin-Hua Li, Yu-Han Wang, Ming-Chi Lu, Tzung-Yi Tsai, Kuei-Yu Chien

Counselor Education Faculty Publications and Presentations

Introduction: With population aging, sarcopenia and its accompanying risk of osteoporotic fracture has drawn increased attention. Nowadays, while Chinese herbal medicine (CHM) is often used as complementary therapy for many medical conditions, its effect against likelihood of osteoporotic fracture among sarcopenia subjects was not fully elucidated yet. We therefore conducted a population-level study to compare osteoporotic fracture risk for sarcopenia persons with or without CHM use. Methods: Using the patient record from a nationwide insurance database, we recruited persons with newly diagnosed sarcopenia and simultaneously free of osteoporotic fracture between 2000 and 2010. Propensity score matching was then applied to …

Changing The Paradigm For Pesticide Resistance Management, David R. Shaw, Amy Asmus, Jill Schroeder, David Ervin

Economics Faculty Publications and Presentations

Collaborative action on the part of all stakeholders in pest management is essential to effectively address the challenges of pesticide resistance. The US Environmental Protection Agency, through its Pesticide Program Dialogue Committee, recently posted a report on pesticide resistance management and the role the Agency can play in these efforts. In this perspectives piece, we commend the Agency for acknowledging these needs, and encourage implementation of the recommendations. We urge all stakeholders to follow the example set by EPA to engage openly, listen to other stakeholders, and determine their role as part of the broader community that is needed to …

More Than Fiction: Representations Of Youth In Young Adult Dystopian Fantasy Fiction And Its Importance, Daman Mcconnell

University Honors Theses

This article takes on a comparative analysis between Young Adult Dystopian literature like Leigh Bardugo's Six of Crows and Suzanne Collins's The Hunger Games, focusing on how adolescents are represented in the discussion of Dystopian Fiction. Though mainly focusing on Six of Crows, these novels can be considered places where society and the world these characters live in are unforgiving and restrictive, forcing the growth of these adolescents to accelerate toward adulthood. Within Six of Crows lies the representations of antagonists going against the youth as adults with twisted senses of morality. In addition, this article also discusses …

Understanding The Crisis: The Evolution Of Indigent Defense In Oregon, Molly Pettit

University Honors Theses

On any given day in Oregon, hundreds of people charged with a crime do not have an attorney to represent them. Many of these people are in custody, and some face charges as serious as murder. How did our public defense system reach the point of crisis? What can be done about it? This paper provides a general overview of the right to counsel nationally before narrowing the focus to the state of Oregon. Using scholarly articles, historical documents, footnotes, meeting transcripts, and interviews, I explore the beginnings of court-appointed counsel in Oregon, and document how it has grown and …

Low Internal Air Space In Plants With Crassulacean Acid Metabolism May Be An Anatomical Spandrel, Alistair Leverett, Anne Borland, Emma Inge, Samantha Hartzell

Civil and Environmental Engineering Faculty Publications and Presentations

Crassulacean Acid Metabolism (CAM) is a photosynthetic adaptation found in at least 38 plant families. Typically, the anatomy of CAM plants is characterised by large photosynthetic cells and a low percentage of leaf volume comprised of internal air space (% IAS). It has been suggested that reduced mesophyll conductance (g_m) arising from low % IAS benefits CAM plants by preventing the movement of CO₂ out of cells and ultimately minimising leakage of CO₂ from leaves into the atmosphere during day-time decarboxylation. Here, we propose that low % IAS does not provide any adaptive benefit to …

Quantifying Damages To Soil Health And Emissions From Land Development In The State Of Illinois (Usa), Elena A. Mikhailova, Hamdi A. Zurqani, Zhenbang Hao, Mark A. Schlautman, Gregory C. Post, George B. Shepherd, Christopher C. Post, Renee M. Dixon

Geography Faculty Publications and Presentations

The concept of soil health is increasingly being used as an indicator for sustainable soil management and even includes legislative actions. Current applications of soil health often lack geospatial and monetary analyses of damages (e.g., land development), which can degrade soil health through loss of carbon (C) and productive soils. This study aims to evaluate the damages to soil health (e.g., soil C, the primary soil health indicator) attributed to land developments within the state of Illinois (IL) in the United States of America (USA). All land developments in IL can be associated with damages to soil health, with 13,361.0 …

Understanding Connections Between Mobility, Transportation, And Quality Of Life In Refugee Communities In Tucson, Arizona, Orhon Myadar, Arlie Adkins, Maia Ingram, Nicole Iroz-Elardo

TREC Final Reports

In this multidisciplinary research project we aimed to study mobility challenges that refugees in Tucson, AZ, experience after their resettlement. Using qualitative and quantitative data collected from interviews and survey data, we argue that mobility shapes the ways refugees foster social connections, attain employment and access educational opportunities. Accordingly, barriers to mobility negatively impact refugees’ perception of well-being in post resettlement. However, these challenges are not experienced evenly. Nor are refugees passive subjects who lack agency in overcoming various barriers they experience. The study reveals the resilience of the refugee community in navigating the intersectional challenges they confront related to …

Bought But Never Used: How And When Unused Utility Reduces Subsequent Spending, Shruti Koley, Brandon J. Reich

Business Faculty Publications and Presentations

Consumers often buy products that they later do not use. How does failing to use purchased products affect subsequent spending? Six experiments demonstrate that when consumers do not use their purchased products, it decreases their subsequent discretionary spending across product categories due to an aversion to wasted money. We find that this effect is driven primarily by perceived money waste and not product waste. Consequently, the effect persists even when consumers avoid product waste, such as by donating their unused products, but is mitigated when they avoid money waste, such as when their unused products are freely acquired. We also …

A National Typology Of Health Service Regulation In Assisted Living, Lindsey Smith, Paula Carder, Cassandra Hua, Sheryl Zimmerman, Philip D. Sloane, Wenhan Zhang, Christopher J. Wretman, Portia Y. Cornell, Kali S. Thomas

Institute on Aging Publications

Background and Objectives

State regulating agencies use 350 different licenses and certifications to govern assisted living (AL), resulting in significant variation in regulations governing health services, the scope of practice, and capacity. This lack of standardization makes it difficult to compare and contrast AL operations and residents’ outcomes across similarly regulated communities.

Research Design and Methods We used qualitative and quantitative methods to empirically develop and describe a typology of state AL regulations that captures inter and intra-state variation. Based on the rules governing health services, we created regulatory specificity scores for five thematic dimensions: medication administration, third-party care, skilled …

Schlosser, Jorge Gutierrez, Jess C. Mace, Todd Bodner, Timothy L. Smith, Jose L. Mattos, Vijay R. Ramakrishnan, Jeremiah Alt, Zachary M. Soler

Psychology Faculty Publications and Presentations

Background

It is unclear if chronic rhinosinusitis (CRS) endotypes show differential response to endoscopic sinus surgery (ESS). We explored mucus inflammatory cytokine expression in a cohort with CRS and associations with both patient-reported and clinically measured postoperative outcome measures.

Methods

Patients with CRS were prospectively recruited between 2016-2021 into a multi-center observational study. Mucus was collected from the olfactory cleft preoperatively and evaluated for 26 biomarkers using cluster analysis. Patient reported outcome measures included the Sino-Nasal Outcome Test (SNOT-22) and Questionnaire of Olfactory Dysfunction (QOD). Additional clinical measures of disease severity included Threshold, Discrimination, and Identification (TDI) scores using Sniffin’ …

Describing Physical Activity Patterns Of Truck Drivers Using Actigraphy, Bradley Wipfli, Sean P.M. Rice, Ryan Olson, Kasey Ha, Caitlyn F. Trullinger-Dwyer, Todd Bodner

Psychology Faculty Publications and Presentations

Background: Truck driving is a highly sedentary occupation that places workers at risk for chronic health conditions, such as obesity and high blood pressure. The primary purpose of this study was to objectively describe truck drivers’ typical physical activity (PA) patterns. Methods: We used w7e10-day baseline PA actigraphy data samples from drivers in the Safety & Health Involvement For Truckers (SHIFT) study (n ¼ 394). Driver PA patterns (e.g., average number of 10 minute Freedson bouts per week, time in bouts, and common days/times for PA) were summarized with descriptive analyses. We also compared objective accelerometer data to self-reports. Results: …

Phase Stability Of Lead Phosphate Apatite, Jiahong Shen, Dale Gaines Ii, S. Shahabfar, Zi Li, Dohun Kang, Sean Griesemer, Adolfo Salgado-Casanova, Tzu-Chen Liu, Yi Xia, Multiple Additional Authors

Mechanical and Materials Engineering Faculty Publications and Presentations

Recently, Cu-substituted lead apatite LK-₉₉ was reported to have room-temperature ambientpressure superconductivity. Here we utilize density functional theory (DFT) total energy and harmonic phonon calculations to investigate the thermodynamic and dynamic stability of two lead phosphate apatites in their pure and Cu-substituted structures. Though Pb₁₀(PO₄)₆O and Pb₁₀(PO₄)₆(OH)₂ are found to be thermodynamically stable (i.e., on the T=₀K ground state convex hull), their Cu-substituted counterparts are above the convex hull. Harmonic phonon calculations reveal dynamic instabilities in all four of these structures. Oxygen vacancy formation …

Formalizing Stack Safety As A Security Property, Sean Noble Anderson, Roberto Blanco, Leonidas Lampropoulos, Benjamin C. Pierce, Andrew Tolmach

Computer Science Faculty Publications and Presentations

The term stack safety is used to describe a variety of compiler, runtime, and hardware mechanisms for protecting stack memory. Unlike “the heap,” the ISA-level stack does not correspond to a single high-level language concept: different compilers use it in different ways to support procedural and functional abstraction mechanisms from a wide range of languages. This protean nature makes it difficult to nail down what it means to correctly enforce stack safety.

Evaluating How Well Active Fault Mapping Predicts Earthquake Surface-Rupture Locations, Chelsea Scott, Ramon Arrowsmith, Rachel Adam, Christopher Madugo, Joseph Powell, John Ford, Brian Gray, Ashley Streig, Multiple Additional Authors

Geology Faculty Publications and Presentations

Earthquake surface-fault rupture location uncertainty is a key factor in fault displacement hazard analysis and informs hazard and risk mitigation strategies. Geologists often predict future rupture locations from fault mapping based on the geomorphology interpreted from remote-sensing data sets. However, surface processes can obscure fault location, fault traces may be mapped in error, and a future rupture may not break every fault trace. We assessed how well geomorphology-based fault mapping predicted surface ruptures for seven earthquakes: 1983 M 6.9 Borah Peak, 2004 M 6.0 Parkfield, 2010 M 7.2 El Mayor–Cucapah, 2011 M 6.7 Fukushima-Hamadori, 2014 M 6.0 South Napa, 2016 …

Institute on Aging Publications

Objectives: This study investigated whether fluoride was associated with an increased prevalence of high blood pressure (BP) among adolescents in the United States. Methods: The study sample consisted of 2015–2016 National Health and Nutrition Examination Survey participants aged 13–17 years. Independent-samples t-tests, Chi-square tests, and regression models were used to analyze the data. Results: A total of 814 participants met the study criteria. The findings showed that the proportion of patients with high levels of water or plasma fluoride in the high BP group was higher than that in the normal BP group. However, after adjusting for sociodemographic covariates, neither …
