In the United States, children from underserved racial/ethnic backgrounds encounter greater environmental risk both in terms of the physical environment (e.g., housing quality, access to resources like health services and jobs, and exposure to environmental toxins) and the social environment (e.g., social support, neighborhood crime, racism, and discrimination), due to...
The coronavirus pandemic and its associated public health response resulted in disruptions in daily life as well as financial and other insecurities. This corresponded with an increase in adverse mental health outcomes in adolescents in the United States, including a temporary increase in suicidal ideation and behaviors. The pandemic also...
During the first full school year of the Covid-19 pandemic, two central contexts for adolescent development—home and school—changed utterly. In Oregon, most middle- and high schoolers attended school entirely remotely from the beginning of the pandemic, in March, 2020, through the end of April, 2021, removing both the supports available...
Self-regulation, defined as one’s ability to control their behaviors, cognitions, and emotions, is an important factor for children’s social, behavioral, and long-term academic performance. Speech/language skills have long been theorized to be important factors in the development of self-regulation and have been linked to various developmental outcomes, particularly in the...
Long-standing research has highlighted the critical role of physical and outdoor activities for children’s health and wellbeing. During the COVID-19 pandemic, children and youth around the world experienced heightened stress and poor mental health, which coincided with a decrease in active play and increase in screen-based activities. This work aims...
The distribution of mobile marine predators often reflects underlying dynamic ecological processes. The geographical focus of this PhD is the South Taranaki Bight (STB) of New Zealand, where wind-driven coastal upwelling generates productivity and prey to support a blue whale foraging ground. The STB is also New Zealand’s most industrial...
Suicide has become a national health crisis over the last twenty years in the U.S as rates have increased 35%. Rates of suicide among rural and youth (10-24 age range) populations have been shown to disproportionately contribute the most to upwards trends though, and this is especially true in Klamath...
At a time of rapid global change, a socio-ecological system (SES) approach can provide a framework through which to quantify and communicate the risks and uncertainties of coupled human-natural systems. Islands, and tropical coral reef islands in particular, can be excellent models for SES research since they may be considered...
Ideally, dosimetric models for pine trees will accurately reflect the doses to its critical organs. However, existing models (e.g. that in ICRP 108) for the pine tree are over simplified or solely focused on estimating doses to one specific organ, and none of the existing models attempt dosimetry to the...
Over the past 42 years clay smoking pipes have been excavated from two U.S. army posts, Fort Hoskins (35BE15) and Fort Yamhill (35PO75) and curated at Oregon State University. These two forts were established in Western Oregon in 1856 and by 1866 both had been decommissioned. Numerous theses have focused...
