Rosenzweig's Elements And Universal History, Martin Zwick

Complex Systems Faculty Publications and Presentations

This paper uses Rosenzweig’s conception of the three elements of God, World, and Human from The Star of Redemption in a model of universal history. The model also has some relation to Rosenzweig’s geopolitical essay, Globus, which is very different from the meta-historical Star. Based on a systems-theoretic schema of events and processes, the model views human history in terms of three linked processes: a primary process labeled “World” – the origin and development of human society embedded in nature, a secondary process labeled “God” – the origin and development of the Axial religions and philosophies, and a …

Key Issues For Speed Safety Cameras: Results From A Semi-Structured Interview Of Agencies In The United States, Sophia Semensky, Miguel Figliozzi

Civil and Environmental Engineering Faculty Publications and Presentations

Speed safety cameras (SSCs) are a recognized countermeasure for targeting speeding-related crashes, injuries, and fatalities. SSCs have been introduced in various cities and are steadily expanding in use both in the U.S. and internationally. The extensive literature review of domestic and international documents and research papers reveals that the U.S. has been comparatively slow to adopt SSCs, with some other countries implementing these systems more extensively and earlier. Many local agencies are eager to learn SSC best practices and implementation lessons within the U.S. context. In this research, key issues related to SSC implementation are explored through semi-structured interviews with …

The conditions for the synthesis of superhard TiN-Cu composite coatings are experimentally determined. Based on established process parameters for TiN synthesis in a nitrogen-containing plasma by Ti evaporation using a vacuum-arc discharge, it is proposed to apply TiN-Cu coatings by injecting Cu vapor into the TiN synthesis area and sputtering Cu using a …

Association Between The Combined Herbal Medicines And Risk Of Dental Diseases In Patients With Rheumatoid Arthritis: Insight From A Nationwide Database, Chiu-Hui Ling, Wei-Jen Chen, Ying-To Hsu, Hanoch Livneh, Ming-Chi Lu, Tzung-Yi Tsai

Leadership, Learning and Counseling Faculty Publications and Presentations

Background and Objectives:

Patients with rheumatoid arthritis (RA) are found to have a higher risk of dental diseases. Although herbal medicines (HMs) have long been used to treat various conditions, few studies focus on its impact on dental diseases. In this longitudinal cohort study, we assessed the correlation between HM use and risk of dental diseases in RA groups.

Materials and Methods:

A total of 2359 persons with RA aged 20–80 who were free of dental diseases between 2001 and 2010 were retrospectively enrolled from nationwide register-based data. They were then classified into HMs and non-HMs groups based on whether …

Expectations And Realities In Primary Care Appointment Access In The United States: A National Study, Brigham Walker, Ethan Tsai, Alexandra Shimanovsky, Edel Doherty, Sarah E. Tinkler, Rajiv Sharma

Economics Faculty Publications and Presentations

Objective: While patients expect timely appointments, little is known about how accurately patient expectations reflect the realities of access to a primary care physician.

Methods: We deployed a national survey (N = 6119, conducted in 2021) to measure patient expectations and a separate national field experiment (N = 11,016, conducted between 2013 and 2016) where trained research assistants called physician offices seeking an appointment to measure physician availability.

Results: Using multivariate regression analyses, we find that patients expected to call 1.9 physicians to secure an appointment, consistent with an appointment offer rate of 49%. However, expectations of 5.4 days wait …

Detecting Eigenvectors Of An Operator That Are Near A Specified Subspace, David Darrow, Jeffrey S. Ovall

Mathematics and Statistics Faculty Publications and Presentations

In modeling quantum systems or wave phenomena, one is often interested in identifying eigenstates that approximately carry a specified property; scattering states approximately align with incoming and outgoing traveling waves, for instance, and electron states in molecules often approximately align with superpositions of simple atomic orbitals. These examples—and many others—can be formulated as the following eigenproblem: given a selfadjoint operator L on a Hilbert space H and a closed subspace W ⊂ H, can we identify all eigenvectors of L that lie approximately in W? We develop an approach to answer this question efficiently, with a userdefined tolerance and range …

Psychometric Analysis Of The German Version Of The Barriers To Healthcare Checklist-Short Form, Judith Peth, Nicole David, Sophia Duckert, Petia Gewohn, Daniel Schottle, Pascal Rahlff, Alexander Konnopka, Hannah Konig, Kai Vogeley, Christina Nicolaidis, Dora M. Raymaker, Holger Schulz

School of Social Work Faculty Publications and Presentations

Background: Autistic people face multiple barriers to health care. To recognize specific barriers in a standardized way, autistic people, health care providers, and researchers need a suitable measure. The Academic Autistic Spectrum Partnership in Research and Education successfully developed the Barriers to Healthcare Checklist— Short Form (BHC-SF). It remains unclear whether (1) a German version of the BHC-SF performs well in terms of psychometric properties and (2) the BHC-SF consists of multiple constructs (i.e., assessing structural validity). Methods: We created a translated and culturally adapted version of the 17-item BHC-SF and used it with 345 autistic people in Germany. Psychometric …

Physiobridge: Physiology-Constrained Self-Supervised Foundation Model For Cross-Device Ecg–Ppg Learning With Conformal Risk Control, Abbas Alzubaidi, Ali Al-Shuwaili, Ali Al-Bayaty

Electrical and Computer Engineering Faculty Publications and Presentations

Wearable and bedside sensors continuously generate electrocardiograms (ECG), photoplethysmograms (PPG), and related physiological waveforms that could enable earlier detection of deterioration and more personalized care. However, current deep learning pipelines in biomedical signal processing often remain taskand device-specific, degrade under domain shift (new hospitals, sensors, skin tones, motion), and provide limited uncertainty information for safety-critical decisions. We propose PhysioBridge, a foundation-model approach that learns a shared representation space for ECG and PPG via self-supervised pretraining and explicit physiology constraints, then supports downstream adaptation with distribution-free risk control. PhysioBridge introduces (i) multi-rate patch tokenization that preserves clinically meaningful morphology across heterogeneous …

When Flood Warnings Fail: Psychological Predictors Of Information Clarity And Evacuation Intention, Katsuya Tanaka, Tadashi Kito, Kohji Tanaka

Center for Public Service Publications and Reports

Flood warnings are often assumed—particularly within traditional average-effect models—to prompt uniform behavioral responses, yet real-world evidence suggests that message effectiveness varies widely across the population. This study empirically identifies and explains such heterogeneity using a factorial survey experiment (n = 1671) conducted among residents in flood-prone regions of Japan. We estimate finite mixture beta regression models to disentangle the distinct behavioral patterns underlying information clarity and evacuation intention. Results reveal two psychological segments: a Responsive majority, whose decisions are shaped by concrete and credible warning attributes (e.g., specific breach point, forecast basis, large-font display), and a Non-Responsive minority, who remain …

Modeling The Combined Effects Of Forest Fire And Climate Change On Snow-Water Storage In The Oregon Cascades, Joseph D. Vigil

Dissertations and Theses

Forest fire and climate change are reshaping the snow hydrology of the Pacific Northwest of the United States, yet the combined effects of these disturbances on snow accumulation, storage, and melt timing remain poorly quantified in these Mediterranean mountain watersheds. This study integrates field-based snow and radiation observations with physically based modelling to evaluate how postfire forest structure, postfire snow albedo decay, and future climate change influence snow-water storage in the Breitenbush watershed of the western Oregon Cascades. This work was conducted as part of a broader U.S. Army Corps of Engineers effort to improve postfire hydrologic prediction and flood …

Otolith Stable Isotopes And Maaori Archaeology: Marine Paleoclimate Data For Northern Aotearoa New Zealand, Reno Nims, Caitlin Smith, Matthew Campbell

Anthropology Faculty Publications and Presentations

Marine paleoclimate records for the last 1,000 years are scarce in the southwest Pacific, limiting our understanding of complex environmental changes that may have affected Ma ori seascapes and fisheries. We seek to begin filling this knowledge gap by studying stable oxygen (δ18O) and carbon (δ13C) isotopes in archaeological and modern otoliths from ta mure (Australasian snapper, Chrysophrys auratus), which provide information about water temperature, salinity, and fish diet and metabolism. Our results show that fourteenth and fifteenth century ta mure otoliths recorded environmental conditions that are comparable to twentieth century temperatures, with some evidence for anomalously warmer seas and/or …

Purpose:

The purpose of this study is to examine how the sequencing of budget simulations influences the alignment between priority goals and budgetary decisions. Drawing on behavioral perspectives, the study posits that two simulation sequences—goal setting to budgeting (default) and budgeting to goal setting (alternative)—shape individuals' budgetary responses, particularly the proximity between a program's total cost and the corresponding budgetary allocations. Design/methodology/approach This study employs a quasi-experimental research design using Balancing Act modules that enable participants to articulate their priority goals and corresponding resource allocations. Adult Americans (aged 18 and above) were recruited through an online crowdsourcing platform and randomly …

Evaluating The Impact Of Leading Pedestrian Intervals And Curb Extensions On Conflict Frequency And Severity, Sophia Semensky

Dissertations and Theses

Leading Pedestrian Intervals (LPIs) and curb extensions are commonly implemented countermeasures intended to improve pedestrian safety at signalized intersections. While LPIs have a well-established crash reduction record, fewer studies have evaluated their impacts using surrogate safety measures or examined how curb extensions interact with LPIs to influence pedestrian-vehicle conflicts. This thesis investigates the effects of LPIs and curb extensions on pedestrian safety using detailed conflict data collected at eleven signalized intersections in the Portland, Oregon metropolitan area.

Approximately 600 hours of video data were collected across four matched intersection pairs and three before–after sites. Pedestrian and vehicular volumes, turning speeds, …

Reinvesting In A Lived Experience Workforce: An Exploration Of Why Peer Support Specialists Leave The Field, Morgan Rae Pelot

Dissertations and Theses

Peer support specialists (PSSs) are individuals who use their lived experience of mental health challenges along with formal training to provide peer support to other individuals experiencing similar challenges. PSSs have only become integrated into the mental health care system within the last several decades. Recently, a study reported a trend of PSSs leaving the field of peer support, but there is a gap in the literature exploring factors that may influence this decision. This study examined if self-efficacy, motivations to join the workforce, and negative work experiences were related to workforce retention. A secondary cross-sectional analysis was conducted on …

A single-basin automatic calibration run can typically be completed on a modern laptop in …

Promoting Methane Reductions Through Behavioural Nudges And Informational Boosts: A Field Choice Experiment In Japanese Rice Farming, Shengyi Du, Katsuya Tanaka, Hiroki Sasaki, Tetsuya Horie, Shinya Horie

Center for Public Service Publications and Reports

Agricultural methane emissions represent a significant contributor to global climate change, with irrigated rice cultivation beingone of the primary sources. Despite the availability of effective mitigation technologies, their adoption often remains limited dueto behavioural and institutional constraints. Water management practice that extends drainage periods during cultivation cancurb methane emissions from irrigated rice at low cost, yet uptake among Japanese farmers remains modest. We surveyed 2219rice producers in Shiga Prefecture using a labelled choice experiment that embedded two behavioural nudges (social norm andloss aversion) and one informational boost (knowledge enhancement), presented with or without a reminder. Farmers most fa-voured a 7-day …
