Phytoplankton Community As An Indicator Of Cyanobacteria Harmful Algal Blooms In High Mountain Lakes, Victoria Elizabeth Avalos

Dissertations and Theses

Cyanobacteria blooms are a growing issue worldwide and can be harmful to both aquatic life and human health. Warm temperatures, nutrient loading, stable water columns, and selective grazing of zooplankton and phytoplankton can contribute to cyanobacteria bloom formation. In this study, I characterized the algal communities and water quality differences in two physiographically similar lakes with relatively little human influences, Odell and Crescent Lakes, Oregon, to better understand potential contributing factors to cyanobacteria harmful algal bloom formation (cyanobacteria bloom) in Odell Lake.

There are three hypotheses in this study:

1. If there was a cyanobacteria bloom in Odell Lake, but not …

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 …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Objectives

This study aimed to examine the intergenerational effects of maternal adverse childhood experiences (ACEs) and child mental health outcomes in rural Uganda, as well as the potentially mediating role of maternal depression in this pathway. 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. …

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 …

Most Vulgar And Barbarous: A History Of Tattoo Stigma, Sophie Luzier

Young Historians Conference

For thousands of years, tattoos have been used cross-culturally for purposes ranging from religious affiliation to ritual. Still, many societies today associate tattoos with deviance and criminality, making it difficult for tattooed people to find employment and acceptance within society. This negative stigma can be traced all the way back to Ancient Greece, when tattoos were used to mark slaves and prisoners of war. Other examples are given from Dynastic China, Japan, the American circus, and the Holocaust. This examination of tattoo stigma throughout history exposes larger patterns of racism, hegemony, and ostracism, and gives us an awareness of social …

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? …

“An Impediment To Those Who Would Walk The Difficult Way”: How St. Francis Of Assisi’S Revolution In Catholic Thought Was Built On The Perceived Inferiority Of Femininity, Julian F. Balsley

Young Historians Conference

St. Francis of Assisi is undoubtedly one of the most famous saints in the Catholic Church. Known for his complete poverty and deep love for the poor and animals, the Little Poor Man of Assisi has become renowned for his way of life and the fraternity he started that has continued for over eight hundred years. In an organization rife with cardinal sin, Francis was in stark contrast with his asceticism and rankless order. However, St. Francis’ entire ideology is built on the Catholic belief that women are inherently inferior to men and dangerous to those following God. Francis used …

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 …

The Contribution Of Domestic And International Conflict In Renaissance Italy To The Sport Of Fencing, Amelia E. Nason

Young Historians Conference

Fencing, the art or practice of attack and defense with the foil, épée, or saber, has progressed over hundreds of years from the warfare of Germanic tribes to a regulated Olympic sport. This paper investigates the development of fencing during the fifteenth and sixteenth century Italian Renaissance and outlines a variety of ways that fencing culture mirrored Italy’s at the time, demonstrating that Italian fencing was a product of both international and domestic conflict beyond the sport itself. The competitive cultural influence of aesthetic epicenters such as the Florentine Republic over other European countries—particularly France, Spain, and Italy—was paralleled by …

A Double Edged Blade: Contrasting Theories Of Dissection Within 16th Century Italy, Sarah Zdebski

Young Historians Conference

Up until the Middle Ages, dissection was largely nonexistent. Gory and unsettling to the modern eye, physicians and anatomists alike agreed that animal dissections and comparative anatomies were more than sufficient to map out the human body. When academic dissections did begin to occur with regularity, they were rigid and formal in nature, relying on inaccurate anatomical texts written over a millennia ago by the Greek physician Galen. Dissection was a visual exercise, conducted primarily in Italian universities to provide a gory illustration for the medical student. The established format for dissection at the beginning of the 16^th century …

Law And Cultural Attitudes Towards Abortion: Ancient Civilizations To Present, Scarlett O. Anderson

Young Historians Conference

Abortion, the termination of a pregnancy, has been practiced throughout history in various forms and frequencies. The controversy of the procedure has prevailed similarly, evident from its earliest documentation to recent legal decisions. Statutory legal sanctions were scarce in ancient civilizations, and differing opinions were recorded in early medical, religious, and philosophical texts. These texts influenced centuries of common law & cultural attitudes toward the practice. Debate about the role of fetal viability, ethicality, and safety of the procedure wove their way into the public conscience. These ancient conceptions influenced the widespread emergence of statutory abortion law in the 19th …

Institutionalizing Femininity: A History Of Medical Malpractice And Oppression Of Women Through 19th Century American Mental Asylums, Ciara E. Pruett

Young Historians Conference

“Institutionalizing Femininity” explores the origins of the medicalization of gender norms in 19th century mental asylums. This paper examines the connections between rampant medical malpractice in 19th century American mental asylums, and how these abuses were a symptom of the patriarchy in the medical community acting to oppress the female psyche. One of the major issues this paper examines is the indistinguishability between psychiatry and gynecology in this time period. Gynecologists created the notion that women’s reproductive organs made them insane, by arguing that issues in the uterus or reproductive organs, or simply possessing female reproductive organs could cause insanity. …

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 …

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

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 …

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.

Impacts Of Floodplain Restoration On Water Temperature And Macroinvertebrates In Whychus Creek, Oregon, Wesley Nathan Noone

Dissertations and Theses

Stream restoration is a proposed climate adaptation tool, however, outcomes of floodplain restoration on stream temperature have been debated. Despite a growing number of studies that investigated water temperature in restored streams, few have quantified thermal heterogeneity in new habitat types created by restored hydrogeomorphic processes and the impact of thermal diversity on the aquatic macroinvertebrate community. In this study, I evaluated three hypotheses: 1) restoration increases habitat diversity, 2) habitat diversity increases water temperature heterogeneity, and 3) restored reaches have more diverse macroinvertebrate communities. I collected a total of 40 macroinvertebrate samples and characterized environmental conditions in three reaches …

Liquefaction Triggering In Low-Plasticity Silts And Effects Of Liquefaction-Induced Lateral Spreading On A Reinforced-Concrete Pile, Jared A. Martinez

Civil and Environmental Engineering Master's Project Reports

Liquefaction triggering and post-liquefaction effects on lateral loading of deep foundations is an emerging area of study. This project presents: the results of cyclic direct simple shear (CDSS) testing on a low-plasticity alluvial silt collected in Portland, Oregon; and analysis of the combined effects of liquefaction-induced lateral spreading on a reinforced-concrete pile using data collected from a shake table test. The former research determines the liquefaction susceptibility and post-liquefaction characteristics of a local transitional soil using stress-controlled CDSS testing, the latter explores the complex lateral loading a reinforced-concrete pile undergoes during seismic loading with liquefaction-induced lateral spreading of the ground …

Ce-Qual-W2 Performance Assessment Modeling 1979 Grh Flume Study, Logan Negherbon

Civil and Environmental Engineering Master's Project Reports

In an early review of numerical reservoir hydrodynamic models, the US Army Corps of Engineers developed a physical model at the US Army Waterways Experiment Station to assess the performance of modeling cold water underflow with numerous 2-dimensional and 3-dimensional numerical hydrodynamic models. Within this effort, the precursor for CE-QUAL-W2, the Laterally Averaged Reservoir Model, was defined and applied with limited success in representing the vertical velocity profile and outflow temperatures series collected from the physical model in the General Reservoir Hydrodynamics flume. CE-QUAL-W2 has since been modified from this early form in numerous ways including incorporation of higher order …
