Learning Analytics and other branches of Educational Research such as Computing Education Research (CER) implicitly assume that students, especially college students, have no barriers to access learning platforms or software packages. This assumption may be attributed to such pervasive beliefs such as "everyone has a device", or "everyone can access...
Despite an expansive selection of available thin-layer chromatography (TLC) stationary phases, almost none are well-suited for separation of polar, ionic analytes. This work demonstrated that a highly porous stationary phase layer comprised solely of nanostructured biosilica frustules, isolated from living Pinnularia sp. diatom microalgae, improved TLC separation of the polar,...
Genotype data consisting of 10,546 single nucleotide polymorphisms on the Illumina Infinium Genechip BARCBEAN6K_3 platform for 149 snap bean accessions.
This data contains results from direct numerical simulations of three-dimensional, premixed, hydrogen/air flames, using the mixture-averaged diffusion model. We performed the simulations using the finite-difference code NGA; simulation details are described completely in the associated article.
This study sought to understand the commonality of vaccine misconceptions among college students and where individuals feel they are obtaining their vaccine information. An IRB approved survey was used to collect 126 responses from Oregon State University students. Individuals, on average, correctly answered only 54.10% of the statements based on...
Acquiring, maintaining, disseminating, and utilizing quality data is key to adequate understanding and management of ecosystems. Modern remote sensing technology provides us an increasingly cost effective, unique opportunity for acquiring highly detailed information across every square meter of a landscape. The plethora of data available to scientists allows for use...
Microbial communities in aquatic systems are dominant drivers of chemical transformation, including contaminants of emerging concern (CECs). This study quantified shifts in microbial communities and their relationship to shifts in chemical composition in surface waters in the Willamette Valley, Oregon. In addition to bulk chemical composition shifts, the relationship between...
Projected intensification of drought as a result of climate change may reduce the capacity of streams to rear fish, exacerbating the challenge of recovering ESA-listed salmon populations. Without management intervention, some stocks will likely go extinct as stream drying and fragmentation reduce juvenile survival to unsustainable levels. To offset drought-related...
The primary goal of this study is to look at the influence of family communication patterns on behavior and beliefs, specifically in the context of electoral behavior. In order to effectively influence potential voters and increase the likelihood that they intend to vote in federal elections in the long-term, we...
Digital Human Modeling (DHM) is a computational design tool that allows designers to use virtual prototypes of design for exploring ergonomics requirements. DHM brings in the advantage of reducing the time and finances committed to building the physical prototypes as well as minimizing the efforts put on performing human subject...
The benefits of electrification are widely discussed in energy and development literature, but little research to date has studied the impacts of household electricity access on women in particular. Women make up the majority of the world’s poor and are also disproportionately affected by energy poverty because of their social...
Building software systems that adapt to the changing environment is challenging. Developers cannot anticipate all the changes in advance, and even if they could, the effort required to handle such situations is too onerous for practical purposes. Self Adaptive Software (SAS) adapts itself as per changing environment. The area of...
Student engagement has been the focus of much engineering education research, in large part due to its ties to student learning. Widely considered to be a meta-construct, student engagement is often broken down into behavioral, emotional, and cognitive components. Reasons for ongoing research on student cognitive engagement are twofold: educators...
Humans are remarkably efficient in learning by interacting with other people and observing their behavior. Children learn by watching their parents’ actions and mimic their behavior. When they are not sure about their parents demonstration, they communicate with them, ask questions, and learn from their feedback. On the other hand,...
Over the last decades, CMOS-integrated sensors have made impressive progress in performance, form-factor, and energy-efficiency for various applications such as imaging, physical/chemical sensing, bio/health monitoring. In the era of the artificial intelligence (AI) and the internet-of-things (IoT), such CMOS-integrated sensors are essential for massive and comprehensive data acquisition, where sensing...
Research poster for Summer Undergraduate Research Symposium 2019. Research was conducted with CURE funding in the Perez lab studying cellular senescence in the PS19 mouse model.
A 3-minute lightning talk was given by Victoria Keenan at the 2019 Summer Undergraduate Research Symposium on her role as a researcher for the Community Doula Project in Linn, Benton, and Lincoln counties. The presentation provided an insight into the emergent themes identified from the ongoing semi-structured, open-ended qualitative interviews...
Chlorinated solvents are common groundwater pollutants that often exist as mixtures resulting from the use of multiple solvents and their transformation into chlorinated daughter products. These sites are often co-contaminated with the solvent stabilizer 1,4-dioxane (1,4-D), which is not treated by traditional chlorinated solvent remediation techniques. Both 1,4-D and chlorinated...
Heteroaggregation of nanoparticles with naturally occurring colloids has been shown to be an important process in nanoparticle fate and transport in the aquatic environment. The advent of a functional assay to measure heteroaggregation attachment efficiencies has opened the door for further mechanistic studies. It is well known that natural organic...
In today’s world, we are highly dependent on software systems together with devices for almost every task in our day to day life. Software system upgrades are released whenever it is necessary to accommodate the ever-changing user’s needs. The devices we use to run the software systems might be of...
