Predictors Of Cyberbullying And Help-Seeking Behaviors In Rural Midwestern Schools: A Multilevel Modeling Analysis, Ashley M. Harrison-Pavlik

Dissertations

Cyberbullying is a significant problem throughout the United States. Many risk factors have been identified for cyberbullying victimization, including experiencing traditional bullying victimization, social media usage, gender, and underrepresented racial/ethnic status, although the results are inconclusive. In response to cyberbullying, youth may choose to engage in or avoid help-seeking behaviors. Individual characteristics such as age, gender, frequency of victimization, race and ethnicity, and student perceptions of school staff can influence whether a youth seeks help. School level variables, including anti-bullying policies and teacher awareness and perceptions of cyberbullying may also impact help-seeking behaviors. However, few studies have empirically assessed their …

Monitoring And Understanding Momentary Affect Intensity From Smartphone Sensors: Investigating The Role Of Time Resolutions And Semantic Locations, Yiqin Zhu

Arts & Sciences Graduate Student Theses and Dissertations

Momentary affect intensity refers to the momentary strength or intensity of emotional experience and shows wide associations with critical psychological and behavioral phenomena. Traditional self-report approaches to assess affect intensity require people’s attention and are prone to missingness and recall bias. Wide and cheap smartphone access offers opportunities to monitor and understand real-time affect intensity. This study had three specific aims: (a) To evaluate the potential for a state-of-the-art explainable artificial intelligence (AI) algorithm to predict momentary affect intensities without active inputs, we tested how well Temporal Fusion Transformers (TFTs) can predict momentary affect intensity in an unseen test sample; …

Polyphenols For The Mitigation Of Vascular Calcification; In Vitro And In Vivo Studies, Abdullah Altuhami

All Theses

Globally, cardiovascular diseases, in most cases associated with calcification, are the main cause of death. However, currently, the only effective cure is to undergo surgery to augment or receive a healthy donor heart, which could be very difficult due to the long waiting list and the associated risks. The possibility of body rejection of the foreign organs is attributed to immunoreaction or the risk of infection, since the donor must be on immunosuppressant drugs that lower the body's immunity and facilitate the body's acceptance of the new organ as one of its own. Taking that into consideration, using tissue-engineered vascular …

Effect Of Cigarette Smoke Extract And Nutrient Deficiency On Energy Metabolism And Biosynthesis: An In Vitro Intervertebral Disc Explant Culture Study, Avery E. Madden

All Theses

Low back pain consistently ranks among the leading causes of disability worldwide, with degenerative changes in spinal intervertebral discs (IVDs) recognized as a key contributor. Degeneration arises from the disruption of mechanical and biological cues within the disc’s cartilaginous tissue, often exacerbated by aging or injury. In recent decades, cigarette smoking has also been identified as a significant risk factor, as IVD degeneration is more prevalent among individuals with a history of smoking. Smoke inhalation is thought to promote degeneration both directly, by exposing cells to water-soluble toxic chemicals in smoke; and indirectly, through nutrient deficiency resulting from vasoconstriction and …

Effect Of Amino Acid Derivatives And Polyphenol Supplementation On Skeletal Muscle Growth In-Vitro And In-Vivo, Gabriella C. Iheanacho

All Theses

Background

Satellite cells (SCs) are myogenic precursor cells that play a crucial role in muscle growth, and their activity can be influenced by nutrient supplementation. Muscle growth can also be stimulated using growth-promoting hormones; however, there are no approved growth hormones for use in sheep in the United States (Qaid & Abdoun, 2022). This limitation highlights a need to identify alternative compounds that would serve as nutrient supplements to enhance muscle growth and thereby improve meat production. Amino acid derivatives such as guanidinoacetic acid (GAA) and 5-hydroxytryptophan (5-HTP), along with the polyphenol quercetin, are naturally derived compounds that have shown …

Life Cycle Assessment Of The Cultivation Of Lettuce In A Hydroponic System Using The Nutrient Film Technique, Raquel Jordan

All Theses

Hydroponic systems are an emerging method of soilless crop cultivation typically done inside a greenhouse where nutrients are delivered dissolved in water rather than being supplied from the soil. Potential benefits of hydroponic systems include reduced irrigation requirements, higher crop yield per area, and the ability to grow crops year-round in nontraditional areas such as urban settings, cold climates, and sites with contaminated soil. However, hydroponic systems tend to have high energy requirements for lighting and climate control, which can yield significant environmental impacts. To explore the environmental impacts of cultivating lettuce in a nutrient film technique (NFT) hydroponic system, …

Effectiveness Of Electrosynthesized Hydrogen Peroxide In Urease Inactivation For Stabilization Of Source-Separated Urine To Recover Urea, Brooke E. Covert

The Michigan Dental …

Trust Across Difference In Radical Social Movement Organizations: The Case Of The Student Nonviolent Coordinating Committee, Kerstin Miller

Master's Theses

Social movement literature does not properly address trust between activists as a foundation of social movement organizations. This thesis aims to fill that gap by examining how trust within the Student Nonviolent Coordinating Committee, a radical civil rights organization in the sixties, was built and broken over the course of the decade. I drew on first-hand accounts written by SNCC activists to find patterns in how they thought about trust building and trust breaking in their own organization. I found that trust was built primarily through sustained interaction between activists, and that trust in the organization led to activists being …
