Wildfire impacts have intensified in many ecosystems across the western United States due to the combined impact of fire exclusion, climate change, and land management practices. However, on many of these landscapes, fire is a fundamental ecological process that has shaped vegetation structural and compositional diversity, ecosystem function, landscape pattern,...
Influences of tidal and slower (subtidal) oceanic flows over the continental shelf and slope off Oregon are studied using a high-resolution ocean circulation model and comparative model-data analyses. The model is based on the Regional Ocean Modeling System (ROMS), a fully nonlinear, three-dimensional model (using hydrostatic and Boussinesq approximations). The...
Childhood obesity and food insecurity are public health issues that often coexist, and both conditions are more prevalent among rural compared to non-rural populations. Social ecological prevention efforts are recommended, yet limited research has examined how rural family-home environments may influence obesity-preventing and -promoting behaviors. The purpose of this dissertation...
Pacific sardines (Sardinops sagax) are an economically and ecologically important forage fish which transfer energy from planktonic primary producers and secondary consumers to upper trophic predators. Previous genetics studies of Pacific sardine suggested a panmictic population with a shallow genetic structure. However, more than one subpopulation within the Central California...
The number of deaths by suicide each year in the United States is rising. Men, women, and people of all ages die by suicide at high rates. Someone diagnosed with anorexia or bulimia is at significantly greater risk of completing or attempting suicide, making clear the importance of understanding how...
The very essence of talk therapy is rooted in the spoken word between counselor and client. A client’s painful traumatic experiences can often serve as a barrier to accessing the traditional consulting room. Despite the high prevalence of trauma and its status as a known risk factor for nearly all...
The purpose of this dissertation was to add to the professional literature in counselor education and supervision through inquiry and synthesis of research among online teaching, online counseling, and online communities of practice through the supervision lens of the Discrimination Model. A unique, research-informed framework for synchronous online supervision (i.e.,...
With growing recognition of adolescence as the time in which suicidal thoughts and behaviors first occur, early identification and intervention systems in schools have become an international
priority. Understanding and incorporating language indicators associated with the core psychological and interpersonal processes of adolescent suicidality could provide promising tools for school...
The self-help literature is full of texts on both self-compassion and postpartum depression. However, there has been minimal scientific exploration of the literature on these topics. As such, mental health researchers and practitioners have little sense of the psycholinguistic discourse contained in this literature. This study aimed to fill this...
The counseling profession has historically adopted a one-size-fits-all approach toward addressing bereavement. However, there is an emerging paradigm-shift in grief therapy that has been enabled by recent research that differentiates, for example, between types of grief and styles of grieving. This research project contributes to this nuanced approach to grief...
Science is one of the fundamental building blocks of modern societies, and though some science topics are easily accepted by public audiences, others generate intense social controversy by challenging beliefs that are fundamental to a person’s, or group’s, identity. The Theory of Evolution is one of these “hot-button” issues, as...
Household food availability is comprised of both food purchases and foods obtained from alternative sources, like social networks, community services, and household food production. While the food available at home is associated with eating behaviors, diet quality, and health outcomes of children and adults, the literature on food acquisition of...
Acculturative stress can be associated with increased conflicts between Latino parents and adolescent youth, and have negative effects on Latino immigrant parents' psychosocial functioning and parenting practices. Yet, the potentially deleterious effects of acculturative stress on Latino immigrant parents' psychosocial functioning and parenting practices may be mitigated through positive acculturative...
This study was purposed to extract, collate, and statistically format data contained in the national Beginning Postsecondary Students (BPS) Longitudinal Study: 1996-2001database that pertained to persistence and attainment rates of GED recipients who began their postsecondary education at a community college during the 1995-96 academic year. The
primary objective was...
The purpose of this study was to understand the lived experience of students to discern the impact of their interaction with the food pantry. This knowledge may, in turn, influence future food pantry methods and wider policy, both at PNW College and more broadly. Not only does student hunger have...
Phytoplankton are a sentinel class of organisms in the marine environment. Through their photosynthetic activity in sunlit waters worldwide, phytoplankton shape the health and productivity of marine ecosystems and impact the global climate. In this work a range of ocean sensing technologies (via ships, surf zone sampling, moorings, gliders, and...
Numerous diseases and injuries can limit a person's ability to perform everyday tasks -- things like getting dressed, bathing, and eating. Anything that requires physical activity can be affected; even simple things like turning on the lights can become difficult or impossible. Until recently, the only way for a person...
The photoelectron spectra of a series of halogenated
molecules have been investigated in the gas phase. Both
core-ionization energies and Auger kinetic energies were
measured to probe the nature of the interaction that holds
a core electron to the molecule.
It was found that satellite structure (shake) could be
used...
