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 …

The node stores data locally …

A Pattern-Centered Analysis Of Adolescents' Concerns And Hopes About Future Crises: Differences In Ways Of Coping And Personal Adjustment, Melanie J. Zimmer-Gembeck, Katheryn L. Modecki, Ellen Skinner, Lara J. Farrell, Tanya Hawes

Psychology Faculty Publications and Presentations

Introduction

Many adolescents are concerned about global and future crises, such as the health of the planet or terrorism/safety. Yet, adolescents can also express hope about the future. Thus, asking adolescents about their concern and hope could yield subgroups with different ways of coping and personal adjustment.

Method

Australian adolescents (N = 863; age 10-16) completed surveys to report their concern (worry and anger) and hope about the planet, safety, jobs, income, housing, and technology, as well as their active and avoidant coping, depression, and life satisfaction.

Results

Four distinct subgroups were identified using cluster analysis: Hopeful (low on concern …

Caspi: Collaborative Photon Processing For Active Single-Photon Imaging, Jongho Lee, Atul Ingle, Jenu V. Chacko, Kevin W. Eliceiri, Mohit Gupta

Computer Science Faculty Publications and Presentations

Image sensors capable of capturing individual photons have made tremendous progress in recent years. However, this technology faces a major limitation. Because they capture scene information at the individual photon level, the raw data is sparse and noisy. Here we propose CASPI: Collaborative Photon Processing for Active Single-Photon Imaging, a technology-agnostic, application-agnostic, and training-free photon processing pipeline for emerging high-resolution single-photon cameras. By collaboratively exploiting both local and non-local correlations in the spatio-temporal photon data cubes, CASPI estimates scene properties reliably even under very challenging lighting conditions. We demonstrate the versatility of CASPI with two applications: LiDAR imaging over a …

Death And Vengeance Behind Every Corner: The Great Purge And The Psychology Of Joseph Stalin, Isabella Gurin

Young Historians Conference

Under Joseph Stalin’s rule of the Soviet Union, the Purges, or “repressions” as they are now known in Russia, led to the direct and indirect deaths of an estimated twenty million people through starvation, executions, and forced labor camps. As the uncontested dictator of the Soviet Union for nearly twenty-five years, Stalin made no attempt to gain popular support among his nation but enforced his interpretation of communist-socialist rule by means of unremitting oppression and terror. Why did he utilize such vindictive measures? Was it his absolute aversion to any authority and ruthless insistence on total control at all times? …

Odysseus Of The Arctic: The Epic Of John Franklin And The Search For His Lost Expedition, Andy Manne

Young Historians Conference

This paper examines and maps the reasons for the lasting impression and legacy of the search for Sir. John Franklin's disappeared 1845 expedition in search of the Northwest Passage. In the wake of the Napoleonic Wars, burgeoning British Arctic exploration provided a rich foundation for serialized narratives, which, as they played off sentiments of national ambition and imperial pride, inspired a romanticization of the Arctic region and the men who explored it. The search for John Franklin's missing expedition became the epicenter of this trend due to the search efforts of his wife, Lady Jane Franklin, and the controversial findings …

Rite To Death, Left To Life: Death Ritual As A Cross-Cultural Unit Of Analysis, Ro M. Runkel

Young Historians Conference

Death ritual is a nearly ubiquitous aspect of life within civilization, and serves the purpose of reconciling the logical positivist societal constructions that uphold social order with the fundamentally logic-breaking nature of death. This paper posits that death ritual serves as a strong cross-cultural unit of analysis as it provides insight into the defining socio-cultural traits and spiritual outlooks of different cultures. This unit of analysis is applied to Song-era Ch’an Buddhism, pre-colonial Hindu India, and Maori death ritual. For each of these examples, death rites are connected to aspects of art, culture, social organization, and spirituality or religion, and …

Main, Mediated, And Moderated Effects Of Participating In An After-School Social And Emotional Learning Program On Young Children's Development Of Social-Emotional Skills, Amy L. Cordier

Dissertations and Theses

Young children's social and emotional skills (SE skills) are highly predictive of the ease with which they transition to kindergarten as well as their success in the K-12 school system and in life after graduation. Children from low socioeconomic status (SES) backgrounds often enter kindergarten with less well-developed SE skills and lag their peers throughout their school careers. Studies of social-emotional learning (SEL) programs indicate that these programs are successful in teaching SE skills, both in school and in after-school programs. However, less is known about the mechanisms of changes through which SEL programs improve children's SE skills and for …

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

PSU Transportation Seminars

As a social determinant of health, transportation significantly contributes to well-being through several pathways. Researchers and practitioners have called for health indicators as one way to integrate public health concerns into transportation decision-making. However, it is unclear how indicators are used and what their impact is on policy. This case study of five cities explored how health-related indicators are being used in municipal transportation plans, whether they are institutionalized into transportation agency decision-making processes, and what influence they have on administrative decision-making. In addition, this research also explored the conceptual use of indicators as it relates to social learning and …

Increasing Access To Doulas In Oregon: A Delphi Study, Courtney Elizabeth Crane

Dissertations and Theses

Doulas are trained, nonmedical support professionals that provide continuous emotional, informational, physical, and practical support before, during, and after childbirth. Doula care has been shown to reduce the cost of birth-related healthcare, reduce adverse birth outcomes, and increase patient satisfaction and positive birth experience. In 2011 Oregon became the first state to authorize payment expenditures of doula care through Medicaid as a strategy to reduce birth-related health disparities and increase culturally and linguistically appropriate healthcare delivery. The intention of the set of policies and administrative rules was to mandate access to doulas and other types of Traditional Health Workers (THWs) …

An Evaluation Of The Effectiveness Of Innovation Ecosystems In Facilitating The Adoption Of Sustainable Entrepreneurship, Dana Sami Bakry

Dissertations and Theses

Sustainable entrepreneurship has a substantial role of a steadily growing economy and advanced industrial economies. Several strategies have been formed and employed to support the adoption of innovation and technologies in the sustainable entrepreneurship sector. However, the successful outcome of these strategies in achieving their goals depends on how effective they are in satisfying their objectives and thus increasing innovation adoption. One measurement for effectiveness of ecosystem implements can be their support to the input of the process of innovation and technologies adoption and their impact on satisfying regional goals.

The objective of this research is evaluating the effectiveness of …

The Experiences Of American Indian Participants And Site Coordinators In A Gestational Diabetes Risk Reduction Trial, Sarah Stotz, Kelly L. Gonzales, Kelly R. Moore, Heather Garrow, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Gestational diabetes mellitus is the most common complication of pregnancy and contributes to increased risk for type 2 diabetes in both the mother and offspring. We developed and evaluated a gestational diabetes risk reduction and preconception counseling program, Stopping GDM (SGDM), for American Indian females. The purpose of this study is to examine the experiences of American Indian mother-daughter dyad participants and the site coordinators who facilitated the SGDM randomized controlled trial to inform program revisions. We engaged mother-daughter dyads (n = 22 dyads) and site coordinators (n = 6) in focus group interviews. Four themes emerged: (1) …

Discrimination And Perceived Cultural Mismatch Increase Status-Based Identity Uncertainty, Sierra H. Feasel, Tessa L. Dover, Payton Small, Brenda Major

Psychology Faculty Publications and Presentations

Periods of social mobility, such as attending college, can challenge one’s status-based identity, leading to uncertainty around one’s status in society. Status uncertainty is associated with poorer well-being and academic outcomes. Little is known, however, about what experiences lead to status uncertainty. The current longitudinal study investigated discrimination experiences and cultural mismatch as predictors of status uncertainty. We propose that discrimination indirectly predicts increased status uncertainty by increasing perceived cultural mismatch with the university. Participants were Latinx college students, all of whom were low-income and/or first generation to college. Discrimination experiences were measured at the end of participants’ first year. …

Bodyslam: Feasibility Of Tracking Human Kinematics With Simultaneous Localization And Mapping (Slam), Sepehr Laal

Dissertations and Theses

We evaluated a new wearable technology that fuses inertial sensors and cameras for tracking human kinematics. These devices use on-board simultaneous localization and mapping (SLAM) algorithms to localize the camera within the environment. Significance of this technology is in its potential to overcome many of the limitations of the other dominant technologies. Our results demonstrate this system often attains an estimated orientation error of less than 1° and a position error of less than 4cm as compared to a robotic arm. This demonstrates that SLAM's accuracy is adequate for many practical applications for tracking human kinematics.

Beyond “Psychic Income”: An Exploration Of Interventions To Address Work-Life Imbalances, Burnout, And Precarity In Contemporary Nonprofit Work, Robbie W. Robichau, Billie Sandberg, Andrew Russo

Public Administration Faculty Publications and Presentations

Nonprofit scholars and practitioners alike adhere to a long-held assumption that nonprofit work is, and will remain, inherently meaningful work. The long-term marketization of the nonprofit sector coupled with the influence of the COVID-19 pandemic has undercut this narrative. Our research on meaningful nonprofit work indicates that while many nonprofit workers do find their work meaningful, pay, flexibility, and work/life balance are increasingly important to them. This commentary suggests that nonprofit leaders can no longer presume that workers motivated by prosocial values will seek out and stay with nonprofit work, satisfied with the “psychic income” that comes from doing good …

Detecting Fast Frequency Events In Power System: Development And Comparison Of Two Methods, Hussain A. Alghamdi, Midrar Adham, Umar Farooq, Robert B. Bass

Electrical and Computer Engineering Faculty Publications and Presentations

In power systems, frequency deviation from nominal value can occur due to reasons such as loss of generation, loss of load, or major faults in the grid. Such frequency fluctuations can lead to serious subsequent outages and damages to both end-user and utility equipment. Therefore, a proper frequency deviation detection methodology must be in place to effectively identify frequency events in a timely manner. This manuscript provides a comparative analysis between two frequency deviation detection algorithms. One is based on signal processing and statistical analysis. The other is a regression-based algorithm. Both of these algorithms have multiple adjustable parameters, making …
