This technical bulletin contains a calculation of the weighted average of mean scores from published studies involving college students. The measure used in these studies was the Abbreviated Math Anxiety Scale (AMAS). Only reports of the AMAS’ full scale scores were examined. The weighted average for the 17 studies (N...
In the twenty-first century, energy in all its manifestations became the issue of the day. As new insights about Earth’s geo-history emerged, so did worldwide concern about human consumption of fossil energy as a force in global climate change. These insights and concerns added another dimension to anthropological examinations of...
In many undergraduate engineering programs, students do not synthesize content learned from multiple courses until a capstone senior design course. As an example, in undergraduate civil engineering programs, transportation engineering concepts (e.g., geometric alignment, asphalt design procedures) and geotechnical engineering concepts (e.g., shear strength of soils, soil compaction) are not...
The main research goal for this study was to describe how investment into the Hubs has influenced local STEM communities; that is, how STEM Hubs have begun to create opportunities for partnerships, collaboration, connected programing, improved program development or delivery, or improved communication within and outside the STEM teaching and...

The Community Action Partnership of Oregon (CAPO) approached Oregon State University to assist in developing statewide indicators which help local agencies better utilize data for continuous improvement. The project was expanded to include Washington and Idaho. This report summarizes the project's findings.
Two new studies revealed unknown long-distance dispersal and migration movements in sage grouse that offer fresh insights for conservation. Using DNA from feathers dropped at leks, scientists discovered that some grouse (about 1% of populations) travel long distances to explore breeding areas up to 120 miles away—movements that can potentially...

This study seeks to address the following questions: What are the research practices and needs of graduate students? How can new library services and features reduce the gap between graduate student needs and current IR services and features? Semi-structured qualitative interviews were conducted with eight graduate students from different disciplines....
Software (OSS) communities and that women disproportionately experience such barriers. However, this research has focused mainly on social/cultural factors, ignoring the environment itself — the tools and infrastructure. To shed some light onto how tools and infrastructure might somehow factor into OSS barriers to entry, we conducted a field study...
The introduction of an Magnetohydrodynamic (MHD) generator in coal energy plants could potentially allow a 30% increase of efficiency by transforming energy within the channels where exhaust flows. The MHD generator increases efficiency by transforming kinetic energy from the exhaust into electricity by generating a Faraday and Hall current, which...
Since its inception in 1985, the Tri‐State variety development program has primarily focused on the development of processing and dual‐purpose (process and fresh) russets. Recent breeding efforts have focused more on improving genetic resistance to various pests and diseases as a means of lowering production costs. During the past decade,...
Background: Tidal wetlands are important habitats for salmon and a diversity of other fish and wildlife species. They also trap sediment, buffer coastal communities from flooding and erosion, and perform other valued ecosystem services. Tidal wetlands currently exist just at and above sea level, and healthy tidal wetlands are able...
