Analysis of 12 research articles about the developmental and psychological effects of high screen time usage in children under the age of 12.

Food banks around the country are working to alleviate hunger and improve food security for low-income families, seniors, and children through distribution programs and nutrition education. This poster explores the vital role that food banks play in our community and examines how federal budget cuts - especially to SNAP and TEFAP - threaten its ability to serve those in need. By highlighting both research and community data, this project underscores the urgent need to support local food systems and advocate for sustainable food assistance programs.

This project explores the use of deep learning models to map homeless encampments in Eureka, CA, with a particular focus on areas within flood zones that may potentially impact the coastal ecosystem of Humboldt Bay. The project critically examines the ethical implications of using artificial intelligence in this context, particularly with respect to the privacy and dignity of homeless individuals. The study balances technological advancements in geospatial data analysis with the need for responsible and humane applications of AI, ensuring that the potential environmental impacts of encampments are addressed without stigmatizing vulnerable communities.

This review explores how parenting styles in North and South America influence children later in life. By examining a range of studies from both regions, we analyzed the long-term effects of different parenting approaches on individuals as they grow into adulthood. Parenting styles explored in our research include authoritarian, authoritative, permissive, and uninvolved. Studies also evaluated additional influences on parenting such as overprotectiveness and patriachal influence. The goal is to understand better how cultural and regional differences in parenting can shape emotional, social, and psychological development over time.

This project examines how the Arcata Marsh and Wildlife Sanctuary in Arcata, CA, serves as a "third place" for the local community. A "third place" refers to social spaces where people gather outside their homes and workplaces, fostering community interaction and well-being. This study uses semi-structured interviews and observational surveys to assess who uses the Marsh and how the site facilitates this role. The free, outdoor nature of the sanctuary makes it particularly accessible to a wide range of individuals, encouraging community engagement. The project highlights the significance of the Arcata Marsh as a welcoming, open space where people connect, relax, and engage in recreation.

This research represents the preliminary results of a longer term project in Sequoia National Park, California. I used temperature dataloggers to investigate western pond turtle behavior to better understand their natural history and thus inform monitoring protocol and conservation. These data suggest that snorkel surveys used to monitor turtle populations may be more effective if conducted at night. In addition, these data indicate the potential for intraspecific niche partitioning among turtles according to age. These early results hint at unique turtle behavior that is otherwise difficult to observe for a cryptic species and thereby warrant further investigation.

Charles Darwin hypothesized that bird song and plumage might replace each other. Other studies have also found a negative correlation in the relationship of song and plumage. I surveyed 40 students in Ornithology and Advanced Ornithology classes at HSU in January and February of 2015. Each survey consisted of a song listening portion and a photo slideshow where each participant rated the vocal and visual attractiveness on a scale of 1 to 3. The results showed a negative correlation and found that more experienced birders on average thought that birds were more attractive than less experienced birders.

My research has two components. The first component explores field research techniques involving the integration of small unmanned aircraft systems (sUAS), with mobile mapping tools and geospatial analysis, to generate layers of data for a target study area. The layers include georeferenced orthophotographs, digital elevation models (DEMs), 3D models, common GIS raster transformations, supervised classifications, and false-color composites. The second component explores the use of information technology to develop effective methods for displaying and communicating scientific information to a broader audience.

Disequilibrium reaction rim textures on olivine grains from black dacite from the 1915 eruption of Lassen Peak were measured and coupled with experimental reaction rim growth rates to estimate the duration of magma mixing that took place prior to the 1915 eruption. Reaction rims on 100 olivine grains were measured and the duration of magma mixing prior to the 1915 eruption was estimated to be between 12-17 months. The abundance of reaction rim growth varies during the duration of magma mixing and is evidence that the eruption of Lassen Peak was catalyzed by multiple injections of hot basaltic andesite into a relatively cool and mushy dacitic reservoir magma chamber prior to eruption.

Due to the incompatibility of the Standard Model and General Relativity, tests of gravity remain at the forefront of experimental physics research. At HSU, undergraduates and faculty are developing an experiment that will test gravitational interactions at the twenty-micron distance scale, well below what has currently been tested. The experiment will measure the twist of a torsion pendulum as an attractor mass is oscillated nearby in a parallel-plate configuration which will provide a time-varying torque on the pendulum. The size and distance dependence of the torque variation will provide means to determine deviations from accepted models of gravity on untested distance scales.
