Due to threats of secondary salinization caused by increased saltwater intrusion upstream associated with climate change, this thesis examines how salinity affects the development and oviposition site selection habits of three Oregon coastal breeding amphibians, the Roughskin Newt (Taricha granulosa), the Northern Red-legged Frog (Rana aurora) and the Pacific Treefrog...
The mangrove ecosystem has served as a life-support system to large populations of coastal dwellers in Ecuador for many generations. Diverse communities comprised of multi-racial and multi-ethnic groups have formed along the edge of the mangrove forests throughout the Ecuadorian coast. These groups self-identify as being part of an “ancestral”...
Computational simulations of disks are becoming an important tool to predict the the evolution of protostars and disks to better understand the formation of planets. Past research has shown that the evolution of disks and their protostar can be altered through the interaction between gravity and hydrodynamic instabilities. We perform...
Since the 1960s, Vietnamese scholars have written autobiographical literature catered to the American public though they have not gotten as much recognition as soldier accounts and anti-war literature. These Vietnamese literatures shifted in scope and form with the succeeding waves of refugee resulted from the war in Việt Nam. As...
This presentation examines how the Korean War influenced academic life at Oregon State College and later Oregon State University. By profiling students and faculty involved in the conflict, new insights emerged into how war transforms higher education. Three Oregon State perspectives encapsulate the turbulent 20th-century geopolitics of the Korean peninsula....
A flipped classroom provides students with course content in the form of videos, readings, and/or simulations that they complete during the time traditionally used for homework assignments while in-class time is devoted to hands-on group learning activities. Project BoxSand is gathering quantitative data on how students in a flipped classroom,...
This study examines the ways in which community college transfer students develop a sense of belonging at the four-year institution. This inquiry was guided by a constructivist epistemology and qualitative methodology. Data was collected through conducting one-on-one interviews and focus groups to gather information on how transfer students develop a...
Background: Legislators, policy-makers, and leaders in higher education and within communities, are increasingly turning to place-based scholarships, or “promise programs”, to encourage college enrollment and address growing public concerns regarding college affordability. One such program, the Oregon Promise, was implemented across the state of Oregon in the fall of 2016....
Analog-to-digital converters (ADCs) are the key building block for sensor applications, such as wireless communications and digital electronics. These applications require ADCs to have medium to high accuracy (normally from 10-14 bits) and relatively low signal bandwidth (ranging from 100Hz-150kHz). Since these applications are often powered by batteries, high power...
Interest in performance specifications has been growing in the civil and construction industry in the past decade. One major focus area has been on understanding how to prolong the service life of concrete structures, since repair and rehabilitation of existing infrastructure have cost many trillions of dollars. Deterioration mechanisms such...
