Climate exerts considerable control on wildfire regimes, and climate and wildfire are both major drivers of forest growth and succession in interior Northwest forests. Estimating potential response of these landscapes to anticipated changes in climate helps researchers and land managers understand and mitigate impacts of climate change on important ecological...
The relative enrichment of skin sebaceous gland lipids with deuterium-labeled α-tocopherol was compared with plasma enrichment to evaluate the delivery of vitamin E to skin. For the first week of this study, each subject consumed a daily dose of deuterated vitamin E (150 mg of an equimolar mixture of RRR-α-[5-(C²H₃)]-(d₃)...
This thesis follows two studies performed with simple robots. The first follows a robot interacting with eight improvisers to create scenes and perform five isolated gestures (towards, away, sideways, spin, and circle) for interpretation. The second follows a group of three robots performing the same five isolated gestures at two...
Self-harm is a frightening phenomenon that affects adolescents and young adults all over the world. While non-suicidal self-injury (NSSI) has a high prevalence rate, it is not a new behavior. One of the earliest documented cases of NSSI was in ancient Greece and it has gained popularity amongst adolescents. NSSI...
The present study examined the process by which couples, in the context
of a heterosexual romantic relationship, participate in sexual activity. As they did
so, their interactions helped to construct their relationship. Social construction
theory and the gender perspective provided the theoretical foundation for this
qualitative research.
Nine heterosexual couples...
Identifying factors related to adolescent sexual activity is an important
issue for health care, education, and public policy. This research explores the
idea that sexual identity relates to adolescent sexual activity and the riskiness of
the behavior. Sexual identity is composed of many factors, including self-esteem,
sexual self-efficacy, body image,...
A subjective model based on county demographic characteristics
and regional variation in election issues was used to predict
county by county election outcome on an effort to repeal mandatory
comprehensive land planning in Oregon. The subjective model consisted
of four county factors: 1) population density; 2) percent of urbanization;
3)...
The study focuses on how to use entertainment method approach to prompt people with best practices for COVID safety. During COVID times, there have been many robots deployed in public places such as social distancing enforcer or a robot that provide facial masks, but few investigations have been done to...
This thesis seeks to make developing multi-robot comedy performances more accessible to developers and performers, and suggests the use of duo comedy for robot-run research experiments. It involved four main steps: technology development, experimental deployments in the general public, the development of the Multi-Robot Comedy Performance System, and an analysis...
User studies in human-robot interaction and social robotics in general involve human participants and their reactions, observations and expectations of robots. This thesis presents two innovative experimental methods aimed at gaining access to high-stakes social data not typically collectable with traditional user studies. The Actor Method provides access to data...
Expressive motion has been found to be a highly effective tool in communicating intent and motivation in single robot human-robot interaction, but work in exploring how groups of robots can use motion in interactions with humans is relatively nascent. There are many additional complexities to consider expanding from single robot...
We do not fully understand reasons behind extinction of populations and species. Consequently, our ability to anticipate extinction (which can be considered a permanent type of an ecological threshold) has remained elusive. In particular, it is not clear how the attributes of episodic disturbance regimes can elicit extinction. In this...
Bud break is a key adaptive trait that can help us understand how plants respond to a changing climate from the molecular to landscape scale. Despite this, acquisition of bud break data is currently constrained by cost, scale, and a lack of information at the plant scale on the environmental...
Citizen science is a term broadly used to describe activities that typically involve the public in the process, methods, and standards of scientific research with the aim of advancing scientific knowledge or application. Engagement in citizen science for project and program volunteers is influenced by much more than an individual’s...

Abstract
Citizen science is a term broadly used to describe activities that
Anthropomorphism is described as the human tendency to see human-like shapes in the environment and robots have the potential to be anthropomorphized. However, it is unclear if anthropomorphic robots are effective in human-robot interactions (HRI). Using the context of hand sanitizer service as an application, this work assessed whether a...
A chair, once placed, will stay put until moved. Or will it? With the rise of technology being embeddable into everyday objects, what if that chair could move itself? Such robotic furniture has been featured in advertisements, art, and Human-Robot Interaction (HRI) research. Existing methods for operating robotic furniture have...
Being human is often portrayed as desirable in fiction. Many fictional beings, particularly robots and androids, seek out being human as a goal. Although current robotics is not advanced enough for robots and androids to be deemed sentient, the world of fiction is quickly becoming reality. With the integration of...
This capstone report provides an overview of the emergence of the bigleaf maple sugaring industry in Oregon. This report consists of a literature review and three case studies. The literature review compiles information relevant to bigleaf maple sugaring within the wider context of maple sugaring in North America. The three...
Eight studies from a meta-analysis on St. John's wort by Klaus et. al. (1996) were analyzed according to the severity of depression manifest by their patients. The studies were chosen according to inclusion criteria: 1) the study was random, 2) the study compared St. John's wort to a placebo or...
The purpose of this study was to determine new international
students' perceptions of United States professors upon entrance into the
university and after two months in class, and if differences in expectations
exist between groups of students based on demographic variables. A survey
designed to assess these expectations was administered...
