The Association Between Adolescent Mindfulness, Sexual Mindfulness, And Sexual Consent: Does Parent-Child Open Or Controlling Sexual Communication Moderate?, Whitney Lenna Mcewan

Theses and Dissertations

In this study, I investigated how mindfulness and sexual mindfulness (i.e. awareness and non-judgment) related to sexual consent beliefs among adolescents, and how these relationships were influenced by mothers' and fathers' communication about sex. My approach was grounded in Self-Determination Theory, which posits that healthy sexuality is best achieved when self-determined sexual relationships meet the fundamental human needs of autonomy, competence, and relatedness. Previous research has suggested a positive link between mindfulness and sexual mindfulness and sexual consent beliefs among teenagers. On one hand, effective open communication between parents and children, especially regarding sensitive topics such as sexuality, can enhance …

Investigation And Control Of Görtler Vortices In High-Speed Flows, Omar Es-Sahli

Theses and Dissertations

High-amplitude freestream turbulence and surface roughness elements can excite a laminar boundary-layer flow sufficiently enough to cause streamwise-oriented vortices to develop. These vortices resemble elongated streaks having alternate spanwise variations of the streamwise velocity. Following the transient growth phase, the fully developed vortex structures downstream undergo an inviscid secondary instability mechanism and, ultimately, transition to turbulence. This mechanism becomes much more complicated in high-speed boundary layer flows due to compressibility and thermal effects, which become more significant for higher Mach numbers. In this research, we formulate and test an optimal control algorithm to suppress the growth rate of the aforementioned …

Scalable And Explainable Self-Supervised Motif Discovery In Temporal Data, Somayeh Bakhtiari Ramezani

Theses and Dissertations

The availability of a scalable and explainable rule extraction technique via motif discovery is crucial for identifying the health states of a system. Such a technique can enable the creation of a repository of normal and abnormal states of the system and identify the system’s state as we receive data. In complex systems such as ECG, each activity session can consist of a long sequence of motifs that form different global structures. As a result, applying machine learning algorithms without first identifying the local patterns is not feasible and would result in low performance. Thus, extracting unique local motifs and …

Examining The Impact That A Modified School Calendar Had On Teacher Attendance In A Rural Mississippi School District, James W. Carlisle Jr.

Theses and Dissertations

Educational leaders have long recognized the certified classroom teacher as the most important factor in student performance and success.

Advancing Air Filtration Analysis: A Comprehensive Approach To Particle Loading Models, Gentry Nathaniel Berry

Theses and Dissertations

Fibrous air filters are commonly used to capture airborne particles due to their potential for a relatively high capture efficiency and low airflow resistance. Their performance characteristics make them ideal candidates in many instances, spanning a wide range from residential to sensitive industrial applications. However, as more particles are captured, the performance of the filter will evolve. This evolution of performance typically manifests as a higher capture efficiency and higher airflow resistance resulting from the additional particulate deposits. The prediction of fibrous filter performance has been the focus of research for many decades, resulting in numerous analytical, numerical, and empirical …

Advancing Salamander Conservation Efforts In Zoos And Aquaria Through Assisted Reproductive Technologies (Art), Devin Marie Chen

Theses and Dissertations

Salamanders are one of the most at-risk taxa in the world due to habitat destruction, pollution, climate change, invasive diseases, and more. This has led to a need for conservation breeding programs that are often associated with zoos and aquaria. Salamanders can be difficult to breed in captivity, though, due to their dependence on specific environmental cues and other unknown factors that stimulate sperm and egg production.
