Human cathelicidin antimicrobial peptide (CAMP/LL-37) is a cationic antimicrobial peptide that is widely expressed by myeloid and epithelial cells at the human-environment interface. It possesses broad spectrum antimicrobial capacity against bacteria, fungi and viruses. In addition to its direct antimicrobial activity, CAMP/LL-37 also attracts and recruits monocytes, neutrophils and other...
Apologia is a rhetorical genre of self-defense. As such, apologetic discourse
involves a response to an attack upon an individual's character or worth as a human being.
Los Angeles Police Detective Mark Fuhrman encountered such a attack during the 0.J.
Simpson murder trial. The purpose of this analysis is to...
On January 8th, 2011 tragedy struck in Tucson, Arizona. A gunman opened fire on Representative Gabrielle Giffords' "Congress on Your Corner" event, wounding thirteen and killing six ("Arizona Shooting"). Four days later, President Obama spoke to a grieving crowd at the University of Arizona's McKale Memorial Center. This study seeks...
For more than 30 years, researchers have investigated the effects of whole body vibration (WBV) platforms on athletic performance. WBV is a modality in which an individual stands on a vibrating platform to obtain performance effects. Frequency and amplitude of the vibration are the commonly adjusted parameters. The use of...
This study developed a strategic conservation project for the Oregon Coast Aquarium in Newport, Oregon focusing on a signature species and this aquarium’s conservation focus areas (i.e., marine debris, sustainable fisheries, water quality, climate change). This study also examined the potential for incorporating an ecotourism or wildlife tourism component to...
I used program CAPTURE to analyze 1,535 data sets for 33 North American species of small mammals for sources of variation in capture probabilities and to characterize species-specific responses to markrecapture trapping. CAPTURE incorporates seven models to account for all possible combinations of heterogeneity (h), behavioral response (b), and time...
When Biosand filters cannot be constructed with crushed quarry rock due to resource limitations, a suitable alternative filter media is needed. In this research, two crushed quarry rock alternatives were examined. Three bench-scale Biosand filters with crushed rock, beach sand, and heat-treated beach sand media were simultaneously dosed with Willamette...
Forests face health threats from pests and diseases (e.g., mountain pine beetle, emerald ash borer, chestnut blight [CB], Swiss needle cast), and other issues such as climate change. Interventions such as genetic engineering (GE) have shown promise for mitigating some of these threats. CB, for example, has impacted most American...

The number of people traveling to other countries to volunteer for conservation or humanitarian projects has increased dramatically in the past three decades. Despite substantial interest in volunteer tourism, few researchers have examined: (a) the role of promotional material (e.g., brochures, internet websites) in motivating volunteers; (b) factors that attract...
Vibriosis caused by the bacterial pathogen Vibrio tubiashii is one of several factors contributing to mass larval mortalities of the Pacific oyster (Crassostrea gigas) in Pacific Northwest shellfish hatcheries in recent years. Genetically improved strains of the Pacific oyster resistant to V. tubiashii would be highly desirable. This study investigates...
As recreation and tourism visitation increases and government budgets decrease, public
land management agencies are using private commercial operators as an alternative
source of offering products and services. Changes and trends in commercial outdoor
recreation and tourism such as a large scale increase in the number of visitors can affect...

As recreation and tourism visitation increases and government budgets
Connecting with nature is associated with social, physical, and emotional benefits such as stress relief, improved physical health, and lower crime. Parks and other natural areas offer spaces in which to connect with nature and reap these and other benefits (e.g., family bonding, social events, learning). Despite increasing populations of...
Protected area creation, including creation of marine reserves (MRs), is increasingly molded by ecosystem based management (EBM) that integrates biological and social information in the pre and post establishment phases. Collecting social data from large and representative samples of the public (as opposed to other stakeholder groups) before establishing a...
With the baby boomer cohort retiring and arguably having more time for outdoor recreation, coupled with population increases and government agencies encouraging people to recreate outdoors, areas such as state and national parks will likely continue seeing high visitation. It is imperative, therefore, for outdoor recreation managers and researchers to...
Voluntary environmental programs (VEPs) have been created to encourage companies to engage in behaviors that mitigate environmental impacts (e.g., recycling, emissions reduction). Many ski areas participate in the Sustainable Slopes Program, an initiative that promotes VEPs in the ski area industry. Past research has addressed the performance of VEPs in...

Designation of areas as marine wilderness has been proposed as a strategy for managing the increasing threats facing the world’s oceans. Although social factors influence marine protected area success, the human dimensions of marine wilderness remain minimally explored. This thesis examines views of marine wilderness expressed by a representative sample...

Marine environments provide services for ecosystems and humans, but face many threats, including sea star wasting disease (SSWD) and ocean acidification (OA). Biological research on these threats is abundant, but there has been limited research examining the human dimensions of these threats. This thesis contains two standalone articles that explore...
