The science of how people interact socially with robots is still fairly young. One area of ongoing study is how people figure out the way the robot works -- that is, form a "mental model" of the robot. We are especially ignorant of how this happens over time, starting with...

Despite being a highly charismatic and frequently exhibited organism,
Giant Pacific Octopus (Enteroctopus dofleini) population dynamics
are poorly understood. Basic monitoring data for this species is
limited to bycatch and stomach contents of other fisheries species. An
essential step to a better estimation of population size and
productivity is to...
Ice core records provide us a way to investigate past climate and look in detail at past atmospheric conditions. With, on average, higher CO2 concentrations in the Greenland record, the focus of this project was on the potential mechanisms responsible for the higher CO2 concentrations in the Greenland ice core...
This research analyzes the effects of unauthorized immigration on unemployment levels in the states of Texas and California in the United States. Data from the Department of Homeland Security is utilized to best estimate the size of unauthorized populations. This research finds that a one person increase in the unauthorized...
Any interaction with another person requires some judgement of their characteristics from a short amount of time. Each day a person can interact with many individuals and quick judgments have to be made in each situation to decide how to act or react. This means a person can make hundreds...
Fever responses to an immune challenge have been studied in endothermic creatures, but studies of the equivalence is lacking in ectotherms. In this study, heterophil counts were shown to be significantly higher in individuals immune challenged with LPS when compared to a control group. This is indicative of an innate...
Beneficial insects could provide valuable pest control services on Oregon Christmas tree farms, but a limited amount of data exist that quantifies the type and abundance of beneficial insects on farms. This study surveyed beneficial insects on two farms that differed in their management strategies as well as other abiotic...
Seasonality is defined as a change in mood and behavior with the seasons. Research shows there is a possible connection between vitamin D levels and mood (Murphy & Wagner, 2008; Lansdowne & Provost, 1998). Given that vitamin D is produced when skin is exposed to sunlight and varies with sun...
Agrobacterium tumefaciens and Rhodococcus fascians are plant pathogenic bacteria that can induce crown and leafy galls on plants, respectively. Infection by these bacteria results in disfigured, unsellable plants, leading to significant economic losses to the nursery industry. A. tumefaciens and R. fascians are capable of infecting a broad range of...
The origin of hornblendite and other mafic mineral-rich veins found in Cretaceous plutonic rocks from the Northern Cascades is currently not well known. This study seeks to investigate the possible relationship between host plutonic rocks and hornblendite and pyroxene-rich veins by comparing the chemical compositions and petrographic features between the...
Do freshmen achieve less of their personal and academic short-term goals in comparison to upperclassmen?
Some may intuitively assume that due to age, or lack of experience, college freshmen would have lower perceived task-specific ability (self-efficacy) and actually achieve less (goal-completion ranging from 0% to 100%). Differences between various class-standing...
A novel approach for the colorimetric detection of creatinine in a paper/polycaprolactone hybrid microfluidic device using alkaline3,5-dinitrobenzoate (DNB) is described. The reaction parameters of reagent concentration, alkalinity, and analysis time are optimized for fast reaction times and high color yield. Microfluidic devices incorporating this assay are designed and fabricated to...
There are few modern isotopic ages of igneous rocks and polymetallic (Pb-Zn-Ag-Cu-Au) hydrothermal mineral veins of the Mt. Thompson quadrangle in southwestern Montana. Lithology ages of this region vary from approximately 85-80 Ma Butte granite(Kbg) (Lund et al. 2002) to 48.6 Ma of Lowland Creek Volcanic Field (LCVF) (Dudas et...

Salvia hispanica, also known as Chia, is an annual plant of the mint family, Lamiaceae. Chia is a vascular plant with perennating buds initially formed at or within the soil surface. Chia grows to roughly one meter tall at maturity, with leaves growing in opposite arrangement, small purple flowers,...
Consumption of raw dairy products has been linked to diseases such as Salmonella, Campylobacter, E. coli and Listeria. Current retail sale of raw milk in Oregon is limited to disease-free goat or sheep milk. Raw cow milk is legally for sale on farms with less than three cows. Consumers have...
The symbiotic relationship between cnidarians and algae is important to the marine ecosystem due to the photosynthesis produced by the algae and the coral reefs that cnidarians provide. Corals provide their algal partner with a safe home and the algae supply the cnidarians with inorganic materials as a food source....
After a joint injury, arthrogenic muscle inhibition (AMI) leads to decreased neuromuscular control and strength, as neural inhibition prevents volitional activation of the entire motor neuron pool. Traditional rehabilitation techniques such as strength training are unable to effectively reduce AMI and there is a need to identify interventions that can...
Previous research has suggested that how a task is framed can have a significant impact on subsequent performance. These effects seem to be especially important in educational settings where learners are already self-conscious about their likelihood to succeed. Difficult subjects have shown to cause cognitive disequilibrium when confronting dead ends...
Strong self-regulation in early childhood is a key predictor of academic and social success from elementary school through college (McClelland et al., 2012). This study analyzed the influence of the age of the child’s parent on the child’s self-regulation as measured by the HTKS (Head-Toes-Knees-Shoulders) measure. Relations between children’s self-regulation...
