The resurgence of creationism the past few years has been led by advocates
of recent-creationism. These individuals, a minority among creationists in general,
argue that the entire universe was created approximately 10,000 years ago in one six-day
period of time. Recent-creationists support their position by appealing to the
Genesis account...
A quadratic programming method was developed for the statistical
analysis of gas chromatographic data. The method was applied to
three types of flavor extracts, peppermint, hops and brewed tea. The
brewed tea data had to be abandoned because of the singularity of its
coveriance matrix. In all cases tried the...
As part of the continuing investigation of the thermal cis- 1, 3, 5-hexatriene to 1,3-cyclohexadiene rearrangement, four new trienes and a cross-conjugated pentaene have been prepared and their thermal reactions studied. A new route to the synthesis of highly substituted trienes has been developed. The synthesis of three of these...
Design in secondary mathematics teacher education must prepare teacher candidates to do the work of ambitious and equitable mathematics teaching with skill by situating development in the work of teaching and incorporating opportunities to investigate and enact teaching. Teacher education designs must also be responsive to the work that mathematics...
Issues of injustice in society (e.g. racism, classism, sexism, ableism) are perpetuated in and through educational opportunities, including mathematics learning (Freire, 1970/2000). Those that are committed to disrupting the interlocking systems that create disparities and oppression in mathematics education are considered to be “pursuing justice.” Pursuit of justice can involve...
In this dissertation I explore the Arms representation and activities for teaching quantum mechanics invented at Oregon State University. In the Arms representation students embody quantum states. The Arms activities are presented as an exemplar of the unique physics classroom culture of the upper-division Paradigms in Physics program. In the...
In the United States, rates of youth vaping are alarmingly high. In 2018, the U.S. Surgeon General declared youth vaping as an epidemic (Centers for Disease Control and Prevention [CDC], 2022b). However, LGBTQ+ youth are disproportionately affected. In 2021, current e-cigarette use among high schoolers was 16% with heterosexual students...

Modified ride-on cars (ROCs) offer children with disabilities access to independent mobility. Aims: 1) To examine the association between caregiver attitudes towards self-directed mobility, caregiver alignment with the medical and social models of disability, and total modified ROC driving time; 2) To compare caregiver attitudes towards self-directed mobility, caregiver alignment...
This thesis merges the fields of Ecology and Anthropology by applying Habitat Suitability Modeling to the relationship between people and plants in the Pacific Northwest. In it, I create and optimize two Maxent habitat suitability models for camas (Camassia spp.) in Oregon. The first model describes the physical environment of...
