The summary and findings of the 2022 OSU student textbook and course materials survey. This survey was run in March 2022 by the Open Education Resources Unit. It is a derivative of the Florida Virtual Libraries 2018 Student Textbook and COurse Materials survey. The survey inquires about student access to...
Communities throughout the world have grappled with the positive and negative impacts of tourism for years. Oregon State University’s (OSU) Sustainable Tourism Lab was created in 2021 to support such global destinations and help them pursue a sustainable path – inclusive of economic, community, and environmental perspectives. Our first step...
Demands by employers for well-rounded individuals are increasing. Potential employers of fish and wildlife graduates are looking for staff that can communicate effectively, work autonomously, and who can problem-solve (Northwest Center Sustainable Resources 1998). There has been a paradigm shift in curriculum development driven by the requirements of agencies and...
The middle to late Eocene tholeiitic Tillamook Volcanics compose the oldest rock unit in the Hamlet-North Fork of the Nehalem River area. Geochemical plots and field relationships indicate that these rocks were produced in an extensional tectonic setting in the developing forearc and formed an extensive tholeiltic oceanic island. The...
The gradient of a velocity vector field is an asymmetric tensor field which can provide critical insight that is difficult to infer from traditional trajectory-based vector field visualization techniques. I describe the structures in the eigenvalue and eigenvector fields of the gradient tensor and how these structures can be used...
The landing obligation in Europe has been in place since January 1st 2015. Experiences gained so far point out that a number of institutional initiatives have been launched, but in practice little has changed regarding discard reduction and use of discards ashore. In parallel, the wide-ranging EU research project H2020...
A generalized, three-dimensional, finite element bridge model was created in order to efficiently and accurately assess live-load girder distribution factors for a variety of bridge types. This model shortens the time required by bridge analysts to develop individual finite element models for bridges of varying geometries. The creation of the...

3D vector tomography has been explored and results have been achieved in the last few decades. Among these was a reconstruction formula for the solenoidal part of a vector field from its Doppler transform with sources on a curve. The Doppler transform of a vector field is the line integral...
In many traditional computer graphics applications, rendered scenes typically utilize 3D meshes to represent objects within an environment. As the demand to further improve the realism of graphics applications increases, such as for movies and games, it is becoming more important to represent the inner volumes of object meshes. In...
Volcanic hazard maps inform the public on the nature and extent of the hazards that threaten them, but these maps are often challenging for those who are not trained in map use or geology. The maps in this study focus on lahars, a dangerous, fast, and far-reaching volcanic hazard that...
The 4-H Shooting Sports Program strives to enable young people, their
parents, and adult volunteers to become responsible, self-directed, and productive members of society. Agents, leaders, instructors, and coaches must understand the goals and objectives of the program in order to manage or present it properly. These goals and objectives...

The Colombian emerald deposits are globally unique because they are hosted in hydrothermally altered black shales on either side of the Cordillera Oriental. We used electron microprobe analysis to study variations in trace element concentrations in transects across emeralds, and used the ⁴⁰Ar/³⁹Ar dating method to determine the age of...
New detrital mica ages from the Umpqua Group of the Oregon Coast Range provide constraints on models of Eocene sedimentation. Based on sandstone petrography, previous studies assert that the Klamath Mountains to the south are the most likely source region for Umpqua Group sedimentary provenance. However, the presence of Late...
ArcView 3D Analyst is a powerful geospatial tool, and has proven very useful in
3D visualization and analysis. In most cases, 3D data models are temporally static,
representing only one instance in time. For many applications, the 'missing' time
dimension is of great significance, and there is a need to...
