The Role Of Native Hawaiian Spiritual Practices In Social Systems And Environmental Stewardship, Christina A. Hornbaker

Social Sciences

The purpose of this paper is to examine how Native Hawaiian spiritual practices played a role in social systems and stewardship practices. Lightfoot and colleagues (2013) suggest that more archaeological research is needed on traditional resources and environmental management practices. The authors point out that “landscape management practices… are subtle and not prone to leaving smoking guns in the archaeological record” (Lightfoot et al. 2013), which makes such sites difficult to document without ethnographic accounts. Due to this subtlety, I will mainly be pulling information from interviews or oral histories from Hawaiian descendants, early explorers and missionary accounts, ethnographers, and …

Gender, Sex, & Emerging Adulthood, Katarina Andrea Reyes

Psychology and Child Development

Emerging adulthood is a key developmental period when individuals explore and make meaning of their intimate relationships. National trends suggest that experimentation with non-committed relationships has increased (Olmstead, 2020), particularly for females (Netting & Reynolds, 2018). Young women utilize casual sex to explore sex, while men use sex for pleasure (Sizemore & Olmstead, 2017). Moreover, the double sexual standard impacts women’s sexual satisfaction and self-esteem (Williams & Jovanovic, 2018). Little research has examined how sex influences emerging adult’s self-esteem. Previous research has primarily relied on survey data to understand women’s and men’s experiences. Narrative identity scholars posit that individuals can …

The White House: No Drugs Allowed, Olivia A. Jones

Communication Studies

The War on Drugs is a long-term metaphorical war designed to reduce illegal drug distribution, trade, and use by maintaining significant punishment for drug dealers and users. This paper serves to examine how U.S. presidents throughout history have impacted this drug war through their targeted rhetoric and ensuing policies. I examine the research question, “How have presidents used their rhetorical power to perpetuate the War on Drugs while pushing a tough-on-crime narrative that portrays certain drug users and minorities as deviants responsible for crime?” Historical contexts, primary sources, and existing research are used to examine the issue. Using Ideographic Criticism, …

Cityengine As A Tool For Visualizing Neighborhood Change: An Initial Study, Zach Noyes

City and Regional Planning

Urban planning is reliant upon genuine public engagement to ensure that planning and policy decisions reflect the ideas shared by the public. Because planning is a profession largely focused on the physical and built implications of more abstract planning concepts, effective graphic communication is critical to securing public support and understanding of policy decisions. ESRI's CityEngine uses procedural modeling technology to render personally-tailored scenes to non-planner members of the public, and shows potential to positively change the way that planners generate graphic representations of physical impacts of policy changes. This initial study establishes a methodology for determining the efficacy of …

An Analysis And Application Of Pedestrian Streets, Ellie Krantz, Austin Lucero

The PLA/TPS blends have been submerged in a marine environment at the Cal Poly Pier in Avila Beach for 8 weeks. Three sample sets containing three of each blend composition were collected every week and tested in …

Citric Or Acetic Acid Effects On The Crosslinking Of Pvoh, Samuel Carr, Erika Szaldobagyi

Materials Engineering

Transportation and shipping processes are the most dangerous times for food due to harsh handling and frequent temperature changes. Plain corrugated boxes cannot withstand the damp environment caused by melting ice that is used to keep foods cold and fresh. To minimize damage, a protective polymer film coating can be applied. These coatings can be unsafe when used with food and will lead to excess waste by limiting the recyclability of the boxes. The purpose of this project was to produce nontoxic crosslinked PVOH films to determine suitability for a cost effective, biodegradable, and repulpable corrugated box coating. Polyvinyl alcohol …

Soil Degradation Of A Plastic Blend Of Opuntia Ficusindica Juice, Animal Protein And Beeswax, Isabel A. Gamez, Daniel R. Kava

Materials Engineering

Since the introduction of single use plastics in the early 1900s, their usage has increased exponentially. Unfortunately, due to this exponential increase there are negative environmental implications of their production, which requires further consideration. Currently, there are various waste disposal practices for SUPs, including landfilling, incineration, and recycling. Recent data revealed that only 14 % of plastic waste was recycled, with 40% of plastic waste being landfilled, while the rest of the plastic waste was incinerated or released to the environment at 14 % and 32 %, respectively. A potential solution to the plastic waste issue is developing a polymer …
