As such, through a qualitative analysis of 33 interviews with nonreligious couples (N=66 individuals), the current study addresses how nonreligious adults perceive the influence of religious differences on their relationships with their family of origin (i.e., parents, siblings, and extended family members) and how these religious differences impact the intergenerational relationships between nonreligious parent's family of origin and their children. Additionally, …

A Comprehensive Uncertainty Quantification Methodology For Metrology Calibration And Method Comparison Problems Via Numeric Solutions To Maximum Likelihood Estimation And Parametric Bootstrapping, Aloka B. S. N. Dayarathne

All Graduate Theses and Dissertations, Fall 2023 to Present

In metrology, the science of measurements, straight line calibration models are frequently employed. These models help understand the instrumental response to an analyte, whose chemical constituents are unknown, and predict the analyte’s concentration in a sample. Techniques such as ordinary least squares and generalized least squares are commonly used to fit these calibration curves. However, these methods may yield biased estimates of slope and intercept when the calibrant, substance used to calibrate an analytical procedure with known chemical constituents (x-values), carries uncertainty. To address this, Ripley and Thompson (1987) proposed functional relationship estimation by maximum likelihood (FREML), which considers uncertainties …

Assessing Extant Methods For Generating G-Optimal Designs And A Novel Methodology To Compute The G-Score Of A Candidate Design, Hyrum John Hansen

All Graduate Theses and Dissertations, Fall 2023 to Present

Experimental designs are used by scientists to allocate treatments such that statistical inference is appropriate. Most traditional experimental designs have mathematical properties that make them desirable under certain conditions. Optimal experimental designs are those where the researcher can exercise total control over the treatment levels to maximize a chosen mathematical property. As is common in literature, the experimental design is represented as a matrix where each column represents a variable, and each row represents a trial. We define a function that takes as input the design matrix and outputs its score. We then algorithmically adjust each entry until a design …

The Role Of Extracellular Vesicles In Immunomodulation During Bovine Pregnancy, Amber E. Thornton

All Graduate Theses and Dissertations, Fall 2023 to Present

During pregnancy, the maternal immune system must be altered to protect the partially non-self fetus from attack. Our previous studies show an inflammatory response in the uterus of cows carrying somatic cell nuclear transfer (SCNT), commonly known as cloned, pregnancies due to abnormalities in proteins expressed by placental trophoblast cells. Between 30 and 90 days the rate of pregnancy loss is 50-100% for SCNT compared to 2-10% for artificial insemination (AI) pregnancies. Abnormal communication between the maternal and fetal systems during placentation is a major cause of this loss. The trafficking of extracellular vesicles (EVs), membrane-bound cargo carriers, potentially represents …
