A Psychometric Investigation Of The Young Adult Social Behavior Scale (Yasb), Michelle Rene Augustin

Dissertations

Aggressive behavior is a serious public health concern that has resulted in several problems in contemporary society. Despite a considerable body of literature on human aggression, both popular and scientific, a focus on overt physical aggression has obscured other forms of aggression. As a result, considerably less is known about other, more subtle forms of aggression, such as relational aggression. Moreover, research on relational aggression, particularly among older adolescents and adults, has been hindered by the lack of psychometrically sound measures. Research in this area would be enhanced by the availability of such a measure, facilitating comparison of data across …

Regulation Of Biofilm And Antibiotic-Resistance By The Modulator Of Sara (Msa) In Staphylococcus Aureus, Antony Schwartz

Dissertations

Staphylococcus aureus is an important human pathogen that is the causative agent of life-threatening diseases such as endocarditis and osteomyelitis. The ability of S. aureus to thrive as a successful pathogen can be partially attributed to its ability to form biofilm. Biofilm is an extracellular polysaccharide, protein, and DNA-based slime layer that protects the bacterial community. The global regulator sarA is essential for biofilm formation. Since the modulator of sarA (msa) gene regulates several virulence factors and is required for the full expression of sarA, the capacity of the msa mutant to form a biofilm was examined. The mutation of …

A Similarity Matrix For Irish Traditional Dance Music, Padraic Lavin

Dissertations

It is estimated that there are between seven and ten thousand Irish traditional dance tunes in existence. As Irish musicians travelled the world they carried their repertoire in their memories and rarely recorded these pieces in writing. When the music was passed down from generation to generation by ear the names of these pieces of music and the melodies themselves were forgotten or changed over time. This has led to problems for musicians and archivists when identifying the names of traditional Irish tunes.

Almost all of this music is now available in ABC notation from online collections. An ABC file …

The Role Of Puf3p And Puf4p In The Regulation Of Mrna Decay In Yeast Saccharomyces Cerevisiae, Florencia Andrea Lopez Leban

Dissertations

Proper regulation of gene expression at a cellular level is required in all organisms for their successful adaptation and survival to physiological or environmental changes. In eukaryotes, a convenient way of regulating gene expression is achieved by post-transcriptionally adjusting the decay rates of different mRNAs. The Puf family of proteins in yeast belong to a widespread group of eukaryotic RNA-binding proteins that regulate the lifespans of target mRNAs by sequence specifically binding to 3' untranslated regions (UTRs) and modulating their decay rates. For example, the yeast Puf3 protein binds the COX17 3' UTR, stimulating its deadenylation and subsequent decay. However, …

Consistency Of Written Trauma Narratives Over A Course Of Trauma-Focused Therapy, Juliette Marissa Mott

Dissertations

Several of the procedures commonly used in trauma-focused therapies are similar to techniques that have been shown to influence the consistency and accuracy of memory in experimental settings. These techniques include verbalizing a non-verbal memory, repeatedly recalling an event, and recalling an event in the presence of another person. In an effort to examine the impact of such techniques on memory for a traumatic event, and in turn the impact of traumatic memory change on treatment outcome, the present study examined changes in written trauma narratives created over the course of trauma-focused therapy. Participants were PTSD-positive female survivors of interpersonal …

Comparing Perceptions Of Campus Crime Severity Among Community College And Public Four-Year University Students, Loren Morell Lundstrom

Dissertations

In recent years violent crimes on several university campuses have been highlighted by mass media, drawing national attention to the issue of campus crime. Not all college campuses, however, experience the same level of crime. While community colleges serve roughly half of all undergraduates in the U.S., statistically these public institutions account for a much lower percentage of violent crimes than their public four-year university counterparts. With the thought that perceptions and beliefs govern one’s behavior, this study considers the possibility that elements of institutional culture influence student perceptions about campus crime. Two hundred and sixty-five (265) college students, from …
