San Luis Obispo In A Box: Damage Accumulation And Combined Stressor Matching In Accelerated Uv Testing, Cameron N. Causey

Master's Theses

The goal of service life prediction is to accurately predict the useful lifetime of a coating system in a typical service environment. Field testing is the most true-to-life form of service life testing but requires long exposure times, often not quick enough to readily aid redesign in the product development cycle. As an alternative, accelerated weathering chambers are used to speed up coating failure in a laboratory setting. These devices do indeed accelerate failure but often produce failure modes that are not seen in actual service or produce material rankings that are not reproducible. This work explores the principle of …

Developing A Novel Touchscreen-Based Test Of Cognitive Judgement Bias, Ashlyn Hersey

Electronic Thesis and Dissertation Repository

Cognitive judgement bias (CJB) refers to the interpretation of ambiguous stimuli in a negative (pessimistic) or positive (optimistic) way. Negative CJB is observed in depression and anxiety, conditions that burden affected individuals and caregivers. Pre-clinical animal research is key to understanding CJB and developing therapies, so a translationally relevant CJB test would be a useful addition to the existing pre-clinical rodent touchscreen test battery. We pharmacologically validated a mouse touchscreen CJB task using bupropion and tetrabenazine, agents known to induce positive and negative CJB, respectively. Additionally, we validated the task using an ecologically relevant stressor (injection and handling). Bupropion produced …

Perceived And Preferred Methods To Adult Language Learning, Suzie Tse

Theses and Dissertations

The purpose of this research study is to understand the adult language learners in formal learning setting and know what do they perceive as the main methods of teaching and what do they prefer instead. If there is a gap between preferred methods of learning and perceived methods of learning, then there is a need that needs to be addressed. This is important because many students find language learning at best ineffective and at worst impossible. I hypothesize that there will be a difference between adult student perception and preference because student focuses more on speaking and listening skill over …

What Gives? Trust, Risk, Altruism, And Reciprocity Across 76 Countries, Sherwin Mosavat

Master's Theses

Abstract:

The decades-long literature pertaining to gender-specific preferences lies at the intersection of economics and psychology with a primary focus on the correlation between economic development and gender-specific preferences. Better understanding of this correlation has helped researchers understand how individuals make decisions for their education, finances, and occupation. Falk & Hermle (2018) assess the correlation between GDP and various gender-specific preferences including trust, risk, altruism, and reciprocity. In order to better understand the relationship between economic development and gender-specific preferences, I expand on the Falk & Hermle 2018 framework by introducing new macroeconomic, prosocial, and cultural variables as additional explanatory …

This investigation aims to discover how the hydrologic, sedimentologic, and geomorphic effects of dams differ in low latitudes, specifically in high elevation areas. We use the Coca Codo Sinclair Dam on the Río Coca in Napo, Ecuador, as our study site. We employ a multipronged methodology using …

Egypt’S Legal Modernism: Challenging The National Discourse, Mohamed A. El-Deeb

Theses and Dissertations

Egypt’s legal modernity is the story of the modern Egyptian state itself. Reforming the country’s judiciary in the late nineteenth century was meant to achieve ambitious aims beyond the functionality of a justice system. The utmost goal was the country’s independence from the suzerainty of the Ottoman Empire. The judicial reforms modernized the Egyptian state and built a judiciary and legal community like no other place. Egypt achieved its independent judiciary before gaining its political independence. That was a remarkable achievement of the judicial reform. That rich part of Egypt’s modern history is negated and disregarded from public awareness. Not …

Prenatal Alcohol Exposure Induces Anatomical Changes In The Mouse Somatosensory Cortex., Zahra Saad Siddiqui

Dartmouth College Master’s Theses

Atypical tactile responses are implicated in Fetal Alcohol Spectrum Disorders (FASD). Our lab reported diminished tactile sensitivity in young adolescent mice with a history of prenatal alcohol exposure (PAE). Here, I employed immunohistochemistry to investigate the anatomical correlates of altered tactile sensitivity observed in mice with PAE. Using our 3-day binge paradigm, I examined changes in the distribution pattern of pre- (thalamocortical afferents) and postsynaptic (pyramidal neurons) partners involved in processing tactile information in the SSC of Postnatal day (P) 7 mice. In rodents, tactile information is relayed somatotopically to the SSC via TC afferents expressing vesicular glutamate transporter 2 …

Complementing Vehicle Trajectories Using Two Camera Viewpoints, Katsuaki Nakano

Theses

Traffic volume surveying is a crucial activity to get traffic statistics for road management and traffic congestion control. In recent years, the target environment of traffic volume surveying has become more complex, such as the fully automated surveillance of many-way intersections. Further compounding this complexity, some local governments may not be able to install a camera at a high enough elevation to capture the entire intersection due to environmental, legal, safety, or cost restrictions. Therefore, bigger objects such as buses and trucks often occlude other vehicles in the captured image. This occlusion degrades the accuracy of counting and is one …

Evaluating The Relationship Between Parent-Adolescent Communication, Social Media Use, And Psychological Well-Being In Adolescents, Johannah Smith

LSU Doctoral Dissertations

Adolescents, particularly teenage girls, use social media substantially more than any other age group (Boneva et al., 2006; Gross, 2004; Padilla-Walker et al., 2020). Greater social media use has been linked to internalizing and externalizing problems; however, specific social media behavior and the relation to internalizing and externalizing problems is unknown. Additionally, how parent-adolescent communication impacts the relationships has not been explored. This is concerning as specific social media behavior, such as ruminating with peers and general social media addiction, has been linked to adolescents’ psychological well-being. (Sarmiento et al., 2020; Shensa et al., 2017; Nesi et al., 2020). The …

Direct And Indirect Effects Of And Preference For Feedback During The Good Behavior Game In Elementary Classes, Jensen Chotto

LSU Doctoral Dissertations

The Good Behavior Game (GBG) is an effective procedure for reducing disruptive classroom behavior. In this study, students in 3 fifth grade classes selected the rules of the GBG and then experienced the GBG with different forms of feedback delivery for rule violations (vocal and visual, vocal only, visual only, no feedback) on disruptive classroom behavior in a multielement design. All versions of the GBG substantially reduced disruptive behavior below baseline levels. Additionally, in 1 of 3 classes, losing the GBG produced an increase in negative peer interactions immediately following the GBG. Subsequently, students selected which condition they previously experienced …

A Rabbit Model Of Voice Function Changes Caused By The Administration And Subsequent Withdrawal Of Asthma Inhalers, Savannah Forbes Bullock

Theses and Dissertations

Combination inhaled corticosteroids (ICs) are the primary treatment prescribed for patients with asthma; however, voice problems are also associated with ICs. In this study, 32 rabbits were assigned randomly to one of five experimental groups: baseline, induction, induction control, reversibility, and reversibility control. The baseline group received no treatment and larynges were obtained following quarantine. Rabbits belonging to experimental groups received IC treatment twice a day until trained raters noted visible vocal fold changes during endoscopy, which was performed every 2 weeks. When changes were observed, animals were euthanized, and the larynges were harvested from the experimental induction group and …
