An overarching narrative and finding in the first two sections of the following project is how constructed identities construct narratives and policies. Importantly, the constructed identities are most often assigned by those in power to Asian Americans or LGBTQIA+ people, rather than created for themselves by in-group members, and then become …

Problematic Social Media Use In The Context Of Romantic Relationships: Relation To Attachment, Emotion Regulation, And Motivations For Use, Eleni Gogos

Theses

Social media is an increasingly popular form of connecting with others, especially among young adults, but problematic social media use (PSMU) has become a growing concern. Research has shown that people with anxious attachment styles and poor emotion regulation have a greater likelihood of having PSMU (Liu & Ma, 2019), but how social media usage might play a role in these relationships has not been well-studied. This research asked if the association between anxious attachment and PSMU will be affected by both emotion regulation and online social surveillance in romantic relationships as mediating influences. We utilized advanced mobile phone features …

Evaluating The Potential Impact Of Ototoxicant Exposure On Worker Health, Cody Beaver

Evolution, Yajing Yan

Theses

My work is about how, as microplastic invades the earth, humans begin evolving, following the laws of natural selection. Plastic is attached in visual relationships to represent future mutations after decades of absorbing microplastic into the body. Many contemporary films and books discuss cyberpunk and steampunk from an evolutionary perspective. Technologies such as artificial intelligence and mechanical organ transplantation allow humans to evolve. However, I do not want to discuss the impacts of external technology. Instead, I am concerned with how the intrusion of microplastics influences humanity’s slow self-evolution. I divide my work into different stages to explore how humans …

Preservation Of Autonomy In Pediatric Decision-Making, Crystal Brown

Theses

Pediatric patients must rely on proxy decision-makers, usually a parent or guardian, to make their health care choices for them. There are 3 main frameworks in place for such decision-making. The default is usually that the decision-maker will make the decision that they feel is in the best interest of the child. Limitations on the decision-maker are an aspect often discussed with abuse and neglect at the forefront as thresholds for when limitations and intervention are deemed necessary. Concern for the child’s future autonomy is not made a consideration. Instead, the values and beliefs of the decision-maker are used to …

Invasive Species Identification And Monitoring Using Computer Vision, Street View Imagery, And Community Science, Liam Megraw

Theses

Invasive plants present significant challenges for ecosystem integrity, biodiversity preservation, and agricultural production. Continuous surveillance efforts are necessary to detect and effectively respond to emerging infestations. However, monitoring methods currently available each have their own limits, whether due to cost, time, or sampling bias. Computer vision applied to roadside imagery is a previously undeveloped methodological synergy that can support existing monitoring efforts. Further, because roadsides are a vector of spread, they are an ideal pathway to monitor. In this study, we present research and management applications of a dataset generated by a computer vision model for Phragmites (Common reed) and …

Invisible Pain, Hairuo Ding

Theses

My thesis work was the exploration and thinking of the outbursts that can occur out of hiding emotions in people's minds, and the prejudice against mental illness. It was based on a question in my mind: Is psychological injury a real injury? If so, why do people always advocate gratitude for suffering? Why is it that when someone is experiencing frustration and pain, it's just seen as an obstacle to become a better person? What about the scars that these extreme emotions create, the ones that are hidden deep within people's hearts, under the polite and cheerful appearance that they …

On The Use Of Imaging Spectroscopy From Unmanned Aerial Systems (Uas) To Model Yield And Assess Growth Stages Of A Broadacre Crop, Amirhossein Hassanzadeh

Theses

Snap bean production was valued at $363 million in 2018. Moreover, the increasing need in food production, caused by the exponential increase in population, makes this crop vitally important to study. Traditionally, harvest time determination and yield prediction are performed by collecting limited number of samples. While this approach could work, it is inaccurate, labor-intensive, and based on a small sample size. The ambiguous nature of this approach furthermore leaves the grower with under-ripe and over-mature plants, decreasing the final net profit and the overall quality of the product. A more cost-effective method would be a site-specific approach that would …

Numerical And Experimental Investigation Of Aerosol Jet Printing, Srikanthan Ramesh

Theses

Bacterial contamination of medical devices remains a threat to the success of many medical interventions. Oral administration of antibiotics is a convenient, non-invasive way to treat infections. Most orally administered drugs, however, encounter biochemical and biological barriers that reduce their bioavailability at the target site. Therefore, prophylactic physico- chemical changes of biomaterial surfaces are considered alternatives to inhibit bacterial aggregation and subsequent biofilm formation. Millions of years of evolution have enabled nature to develop micro-topographical surface features specifically designed to avoid bacterial attachment and colonization. Examples of such topographies can be seen on insect cuticles, plant leaves, and the feet …
