The purpose of this study was to investigate the relationship between moral development and year in school, gender, and personality type for university undergraduates. Moral development was measured by the Defining Issues Test (DIT) and personality was assessed using the Myers-Briggs Type Indicator (MBTI). The sample consisted of 320 freshmen,...
The purpose of this study was to clarify the relationship between religiosity and sexual behavior of college students by using a measure of religious orientation to define religiosity. Religious orientation refers to individuals' motivations for religious involvement and personal faith. Religious orientations are characterized as being extrinsic, intrinsic, indiscriminately proreligious...
The purpose of this study was to investigate the relationship between college student organization leadership experience and postcollege leadership activity. A questionnaire was employed to gather data to determine Ii there were differences by gender, academic major, and last year of attendance at OSU among former student leaders In: postcollegiate...
To understand the processes that lead to the formation of the oceanic crust, one must know the composition and the depth at which primary melts originate. Towards this end, this dissertation focuses on plagioclase-hosted melt inclusions from plagioclase ultraphyric basalts (PUBs). Plagioclase is usually considered to be the second phase,...
The primary goal of this study is to assess the impact of a subduction component
added to the mantle wedge beneath the Oregon Cascades to the composition and fO2 of
primitive Cascade basalts. Olivine-hosted melt inclusions from compositionally diverse
basalts across the Cascade arc (~100 km) are utilized in an...
The past decade of research has potentiated a revolution in our understanding of mammalian health and evolution by revealing that the gut microbiome plays a central role in mammalian physiology. Our ability to unlock this potential hinges upon the identification of specific groups of gut microbes that elicit effects on...
Agricultural and companion animals are integral to our way of life as they provide us with nourishment, financial resources, transportation, and companionship. However, pets, managed animals in the agricultural industry, as well as wild populations of food animals are all subject to health and mortality risks. The gut microbiome is...
Benzo[a]pyrene (B[a]P) is a common environmental pollutant produced from the incomplete combustion of organic matter, such as fossil fuel emissions. In vertebrates, B[a]P exposure is associated with hyperactivity, though the underlying mechanisms driving this effect are undescribed. Mounting evidence indicates that the gut microbiome, which is the diverse community of...
Microscopic organisms inhabit virtually every niche on this planet, where they perform functions vital to all life on earth. Accordingly, humans host a complex community of microorganisms (i.e. the gut microbiome) that inhabit the gastrointestinal tract and modulate host physiology. Insight into the specific mechanisms through which gut microbes influence...
Investigations of 16S rRNA gene sequences hallmark modern microbiology. These sequences provide culture-independent insight into the abundance and distribution of microbiota and serve as a principle resource through which microbial community diversity is measured. Consequently, researchers rely on 16S gene sequences to test hypotheses rooted in ecology, evolution, and disease....
