Experimental Modification Of Dysfunctional Interpretations In Individuals With Contamination Concerns, Sara Louise Conley Jan 2015

Experimental Modification Of Dysfunctional Interpretations In Individuals With Contamination Concerns, Sara Louise Conley

Graduate Research Theses & Dissertations

Obsessive-Compulsive Disorder (OCD) is a debilitating disorder characterized by obsessions and compulsions that cause noticeable impairment across multiple life domains (American Psychiatric Association [APA], 2013). Various models have been used to describe the etiology and maintenance of this disorder, however, the cognitive-behavioral approach to OCD is the model with the most empirical support and direct treatment implications (Abramowitz, Taylor, & McKay, 2009). Additionally, this approach provides parsimonious descriptions of obsessions, compulsions, and their interrelations (Taylor, Abramowitz, & McKay, 2007). Extensive research regarding the etiology and maintenance of the disorder supports the theory that obsessions and compulsions arise from dysfunctional interpretations …

An Examination Of Parental And Individual Factors In Predicting Ethnic Identity, Cara Allen Jan 2015

An Examination Of Parental And Individual Factors In Predicting Ethnic Identity, Cara Allen

Graduate Research Theses & Dissertations

The current thesis project investigated relationships among family ethnic cultural socialization, self-esteem, phenotype characteristics, and ethnic identity in an ethnic minority college student sample. Consistent with previous research, family ethnic cultural socialization was found to be associated with ethnic identity and self-esteem. Two of the three components of ethnic identity examined were associated with self-esteem. It was found that the relationship between family ethnic cultural socialization and self-esteem was mediated by ethnic identity. Analyses that examined phenotype characteristics as moderators in the relationship between family ethnic cultural socialization and ethnic identity did not reveal significant results.

Rtfa, A Putative Rna-Pol Ii Transcription Elongation Factor Is Necessary For Normal Morphological And Chemical Development In The Opportunistic Plant Pathogen Aspergillus Flavus, Jessica M. Lohmar

Graduate Research Theses & Dissertations

The filamentous fungus Aspergillus flavus is an agriculturally important opportunistic plant pathogen that produces potent carcinogenic compounds called aflatoxins. We identified the rtfA gene, ortholog of rtf1 in S. cerevisiae and rtfA in A. nidulans, in A. flavus. Interestingly, rtfA has multiple cellular roles in this mycotoxin-producing fungus. In this study, we show that rtfA regulates conidiation. The rtfA deletion mutant presented smaller conidiophores with significantly reduced conidial production compared to the wild-type strain. The absence of rtfA also resulted in a significantly decreased or lack of sclerotial production under conditions that allowed abundant production of these resistance structures in …
