MicroRNAs are a highly conserved class of small endogenous RNA, about ~22nt in length, involved in post-transcriptional gene silencing and have prominent roles in disease and development. Though the process of microRNA discovery was once an arduous task, the advent of high throughput sequencing technology has resulted in novel microRNAs...
Drosophila suzukii Matsumura (Diptera: Drosophilidae) are small invasive flies that in the past five years (2009-2014) invaded berry and stone fruit production regions in Europe and the Americas. Evolutionary adaptations, biological traits, and anthropogenic factors have contributed to its current status as a global pest. Females oviposit eggs into ripe...
This capstone project is expected to be published by United States Department of Agriculture Animal and Plant Health Inspection Service Wildlife Services (USDA APHIS WS) as part of a technical series guide available to the public through the website (https://www.aphis.usda.gov/aphis/ourfocus/wildlifedamage/sa_reports/ct_wildlife+damage+management+technical+series). USDA APHIS WS is responsible for mitigating human-wildlife conflict and...
Since the 1970s, the United States government has offered federal tax subsidies for employer-sponsored health insurance. The tax exclusions for contributions to Employer Sponsored Insurance (ESI) has become the largest subsidy for private health insurance. These tax subsidies make up 21.4% of our national healthcare expenditures and 1.4% of the...
For centuries economists have attempted to explain what causes the ebb and flow of the economy. None thus far have been able to perfectly explain the nuances of the economy as a whole. In this paper, I explore the relationship between consumer lending volume and economic growth. Consumer lending is...
The black-footed ferret is a meso-predator within the Great Plains region of North America. Before the 1900s, black-footed ferret populations were self-sustaining in large ecological patches throughout the geographical range of the Great Plains. During the 1900s, various factors such as the systematic extermination of prairie dogs (the primary food...
The American beaver (Castor canadensis) was nearly extirpated by the late 1800's due to the fur trade. Due to reintroduction efforts, it now occupies much of its former range. Beavers are a keystone species and ecosystem engineers, greatly influencing riparian and instream habitats through selective harvesting of plant materials and...
Columbian black-tailed deer (Odocoileus hemionus columbianus) are important economically, ecologically, and culturally as an indigenous species in western Oregon. Oregon Department of Fish and Wildlife (ODFW) observed declines in black-tailed deer populations since the late 1980’s and attributes these declines to reduction in quality and availability of habitat, following the...
The number of Internet news media outlets has skyrocketed in recent years. We analyze
the effects of media proliferation on electoral outcomes assuming voters may choose news
that is too partisan, from an informational perspective, i.e. engage in partisan selective
exposure. We find that if voters who prefer highly partisan...
The increasing volume of young-growth Douglas-fir timber cut in the Pacific Northwest emphasizes the need for more knowledge on the characteristics of lumber sawed from these trees.
The study described here was initiated to learn the extent arid causes of degrade resulting from kiln-drying young-growth Douglas-fir dimension lumber. At the...
This thesis describes a syntax-directed compiler-compiler
called COMCOM which has been implemented by the author on the CDC
3300 under the OS-3 operating system. The theory and terminology
of the parsing method and compiler-compilers in general are briefly
discussed. COMCOM uses Floyd's operator precedence bottom-up
parsing technique which avoids backup...
The Purposes of the Study
The primary purpose of this study was to identify common professional
education competencies needed by public school district
vocational education leaders. Other purposes were to (1) determine
if significant differences existed in vocational education leadership
competencies among respondents as categorized by state, type of
position...
This research explores and aligns a postmodern method in line with a theoretical lens of "strategic political queer/feminism" to understand the construction and positioning of the issue/ problem of same-sex marriage. The method takes shape through a theoretical framework that leads to a political maneuver opening access to the rights...
A guild of three and possibly five tip moths
(Rhyacionia spp.) occurs on ponderosa pine (Pinus ponderosa)
in southeastern Montana, northwestern South Dakota, and
southwestern North Dakota. Trapping results indicated that
many of these species may be flying simultaneously, and
individual species relative abundances showed west-to-east
trends.
Tip moth larvae...
While human tool-use proficiency helped define our history, the cognitive and perceptual mechanics of how humans use tools are not fully understood. This question is of great value to the design of hand-held tools and prosthetics. A prominent theory, tool embodiment, suggests that tool use is facilitated by a flexible...
Many stakeholders involved with stream restoration in the Pacific Northwest have discussed the potential benefits of using beaver dam construction activities (Castor canadensis) as a management tool to improve degraded stream habitat for anadromous salmon species. In addition, there has been growing interest in using nuisance beavers, primarily controlled by...

Many stakeholders involved with stream restoration in
Streams across the western United States are impaired from human alterations that have reduced freshwater habitat by simplifying channel complexity and disconnecting floodplains (Knox et al., 2022; Waples et al., 2008; Wohl, 2014). Climate change is likely to continue exacerbating these risks by warming summer surface stream temperatures (Crozier et...
Black bears (Ursus americanus) in western Oregon and Washington peel bark from conifers in early spring to forage on the sugar-rich phloem and cambial tissues. This provides important energy at a time when similarly attractive forage is scarce. Bears often damage Douglas-fir (Pseudotsuga menziesii) trees in stands that are intensively...
Electrical stimulation of beef carcasses (n=18) did not cause a
significant reduction in microbial population on three different sampling
positions immediately following slaughter. In constrast, significant
microbial reduction (P > 0.05) was found at position 2 (muscle
above aitch bone), but not at position 1 (inside of neck) or position...
Recent state and national standards have increased the interest in engineering at the K-12 level. Science standards, in particular, have begun to make the case for including engineering throughout the K-12 scope of study. Despite the increased attention to engineering, the characteristics and uniqueness of the field of engineering are...
