Withstanding Cruel Teasing: Does Dispositional Mindfulness Fortify Target Immunity?, Ruth Catherine Lewis

Electronic Theses and Dissertations

Cruel teasing can be pernicious for targets' psychological health. In this thesis I examined the extent to which trait mindfulness might mitigate the negative psychological effects associated with cruel teasing. Correlation results confirmed cruel teasing history related significantly and directly, and mindfulness inversely, to poorer psychological health. Moderated regression analyses confirmed that among targets of frequent cruel teasing those with high levels of mindfulness did not evidence the detrimental psychological effects as did those low in mindfulness. Subsequent moderated regression analyses with cruel teasing history, mindfulness, and sexual identity status suggest that when people are low in mindfulness cruel teasing …

The Relationship Between Religion And Attention Deficit Hyperactivity Disorder, Philip B. Mason

Theses and Dissertations

Research shows that religious people have higher levels of self-control. Scientists also hypothesize that individuals with Attention Deficit Hyperactivity Disorder (ADHD) are less likely to participate in religious services which require long periods of attention and self discipline. However, little research has investigated the potential relationship between ADHD and religious participation. Using the National Longitudinal Study of Adolescent Health (Add Health), this study finds (1) mothers’ prayer frequency is marginally related to children’s ADHD symptoms and diagnosis although other religious indicators are not significantly related, (2) childhood religious involvement and affiliation are not significantly related to ADHD symptoms and diagnosis, …

L222w Of Hemagglutinin Affects The Receptor Binding Affinity Of Avian Origin H3n2 Canine Influenza Virus, Guohua Yang

Theses and Dissertations

Emergence of avian origin and equine origin canine influenza viruses (CIVs) in Asia and the United States brings important concerns. Humans are in closer and more frequent contact with dogs than other common hosts of influenza. Thus, CIV is a potential threat to human health. However, little is known about the determinants of CIV host tropism or the transmissibility of CIVs to humans. An amino acid change (W222L) was implicated in modifying hemagglutinin receptor binding by CIV. This was tested using reverse genetics, glycan microarray and virus histochemistry. Glycan microarray demonstrated that avian-origin CIV (H3N2-222W) bind predominantly to alpha-2, 3 …

Cryopreservation Of Equine Spermatozoa: Identification Of Good And Poor Freezer Stallions And Effect Of Sperm Density Per Straw, Abed Sharqy Fahad

Theses and Dissertations

This study was carried out primarily to evaluate the cryo-tolerance of equine semen from four stallions through assessing the spermatozoa motion characteristics with Computer-Assisted Sperm Analysis (CASA). Four stallions were collected during the breeding season (summer). For each ejaculate, fresh and cryopreserved samples were taken for sperm motility characteristics evaluation. Data analysis demonstrated that sperm cells of stallions were significantly affected by (P<0.05) cryodamage. Stallion (A) was cryotolerant, and was classified as a good freezer, whereas stallion (D) was not and classified as a poor freezer regardless of the concentration of sperm. In addition, a concentration of 0.4 x 109 sperm cells/ml had higher percentages of rapid sperm and velocity parameters (P<0.05) compared to 0.8 x 109 sperm/ml. Further research is necessary to identify potential biomarkers for good and poor freezer stallions.

Stalking On The Screen: Examining Media Portrayals Of Relational Stalking Behavior, John Robert Macarthur

Theses and Dissertations

I coded a random sample of 266 movies to test whether previous researcher’s assertions that the media legitimizes unwanted courtship persistence (UCP) and minimizes stalking behavior is true. Consistent with their assertions, I found that the media does frequently depict stories of unwanted courtship persistence, and they were portrayed, on average, as acceptable. Although pursuers were generally portrayed positively, pursuers who engaged in UCP were more likely to be portrayed negatively than non-UCP pursuers. However, UCP pursuers were more successful than non-UCP pursuers in winning over their love interest. Using Cupach and Spitzberg’s (2004) Obsessional Relational Intrusion (ORI) scale, I …

Genomic And Functional Analysis Of Next-Generation Sequencing Data, Philippe Chouvarine

Theses and Dissertations

Advances in next-generation sequencing (NGS) technologies have resulted in significant reduction of cost per sequenced base pair and increase in sequence data volume. On the other hand, most currently used NGS technologies produce relatively short sequence reads (50 - 150 bp) compared to Sanger sequencing (~700 bp). This represents an additional challenge in data analysis, because shorter reads are more difficult to assemble. At this point, production of sequencing data outpaces our capacity to analyze them. Newer NGS technologies capable of producing longer reads are emerging, which should simplify and speed up genome assembly. However, this will only increase the …
