Between 1982-1984 I studied site tenacity and mate retention in Black Terns at Sycan Marsh, Lake County, Oregon. I banded 778 adult Black Terns and used this marked population to test the hypotheses that site tenacity and mate retention would be less for Black Terns which nest in variable marsh...
Youth in foster care often perform at lower levels academically than those not in foster care. Prior research on the nature of the relationships that affect former foster youth's educational path has been inconclusive. Though it is widely believed that positive relationships with faculty, staff and peers is beneficial for...
Background: Previous studies suggested that the professional identity of community college faculty is less than clearly articulated. Lack of clarity with regard to professional identity may have impacts in a number of areas, including recruitment, professional development, and the overall reputation of community colleges.
Purpose: To examine how community college...

This paper seeks to provide a practical answer to the following question: why create a board of directors in a family business? To achieve this, it summarizes the existing research published in the field of family business governance that directly addresses the beneficial role of the board of directors in...
Standard quantum mechanics makes foundational assumptions to describe the measurement process. Upon interaction with a “classical measurement apparatus”, a quantum system is subjected to postulated “state collapse” dynamics. We show that framing measurement around state collapse and ill-defined classical observers leads to interpretational issues, and artificially limits the scope of...
The purpose of this study was to describe the presidential search process at a
newly created community college and to learn how that process reflected the

Specifically, undocumented Latino students are known to select community colleges due to their low tuition cost, proximity to...
Professional development is a critical part of education, especially in career and technical education (CTE). CTE programs have rapidly changing technological foundations, and while the CTE teachers' primary focus is to prepare students for entry-level positions in their occupational areas, CTE teachers are also required to embed academics into their...
As reverse transfer students become a larger part of community college enrollments, it is important to better understand the underlying causes of this nontraditional population’s emergence in the traditional community college system. This quantitative descriptive study found that approximately nine percent of the student body enrolled at Rogue Community College...
Concern about college and career readiness has been expressed in both the
business and education arenas. Employers are calling for entry-level employees with
basic academic skills and educators are being held accountable for student
achievement in academic areas similar to those required by employers. In this
environment, WorkKeys has emerged...
The rising cost of higher education in the United States has created increases in tuition at colleges as well as growing demand from students and families for sources of support in attending college.

As community colleges have responded to shifts in funding structures,
demands from an aging population, the emergence of for-profit competitors, the
development of globalization, and the increasing use of technology, the role of
faculty has evolved and new leadership opportunities have emerged. This study
examines informal faculty leadership at a...
Organizational trust refers to the tendency of individuals or groups within an organization to trust each other. Tschannen-Moran (2004) describes trust as one's "willingness to be vulnerable to another based on the confidence that the other is benevolent, honest, open, reliable, and competent" (p. 17). The purpose of this study...
Many low-income and first-generation community college students face disproportionate challenges in their quest for a college education. They typically balance multiple outside obligations, while being solely responsible for making these decisions without adequate knowledge, guidance, or support (Lyons, 2004). Many students begin college without ever having been responsible for their...
The emergence of modularized curriculum in community college career and technical education (CTE) programs has received substantial attention over the last decade, with researchers suggesting that this type of curriculum redesign may assist with student retention and success.

any subject, we must understand exactly what we are
writing about. As the title tells us, this thesis
deals exclusively with the work and incidentally with
the lives of Robert and Elizabeth Barrett Browning, two
notable nineteenth century poets.
This thesis is based on the excavations of the Robert Newell farmstead (35MA41), excavated in 2002 and 2003 by the Oregon State University Department of Anthropology archaeological field school.

The United States is a global leader in agricultural productivity. Much of its productivity growth can be attributed to public investments in agricultural research and development, starting in the 19th century and continuing until today. Past studies have shown high returns to agricultural research investments, but publicly funded agricultural research...
Population counts of aquatic insects can be a credible indicator of the overall health of a waterway. Stonefly (Plecoptera) larva are very sensitive to chemicals present within the waterway, however obtaining population counts of the larvae can be very labor intensive and thus costly. The BugID project has been working...
Oregon Department of Transportation’s bridge no. 9743b is a multi-span, two-girder steel deck bridge connecting the busy interstates 5 and 205. Vertical cracks have been detected in the welded girder-to-crossbeam connections at the bents. Distortion-induced fatigue is suspected to be responsible for the cracking. Linear elastic beam analysis, 2-D and...
Aquatic insect population counts can be a good indicator of the health, or water quality, of rivers and streams. Stoneflies (Plecoptera) are particularly susceptible to pollution in streams. However, today’s current method for obtaining these population counts requires biologists to examine individual specimens under a microscope for identification to the...
Physical testing of composite sandwich panels in three point bending is an increasingly important aspect of qualifying a composite monocoque for Formula SAE competition.
