Efforts Toward Novel Methods For The Synthesis Of Stereochemically-Dense Pharmacologically Relevant Scaffolds, Lauren Nicole Tumbelty

Theses and Dissertations

Nitrogen is the most common pure element, present in nearly all relevant chemical compounds. It is an essential component of the building blocks of life such as proteins, nucleic acids, amino acids and adenosine tri-phosphate. There is a naturally occurring exchange between living organisms and the atmosphere which begins with the process of fixation. Although nitrogen is naturally abundant, the strength of the triple bond in atmospheric nitrogen prevents its applicability in organic synthesis. Therefore, the development of methods to place synthetic nitrogen into heteroatomic compounds plays an important role in the development of pharmacologically relevant scaffolds. Contained within this …

Marketing Race In British History: An Analysis Of The British Empire Marketing Board Posters (1926-1933), Jules Matthew Maffei

Theses and Dissertations

Contemporary instances of racially charged product imagery are deeply intertwined with history. Products like "Aunt Jemima", "Uncle Ben's Rice", or the indigenous peoples portrayed on "Land O' Lakes" butter affects perception of race, class, and gender. The continued existence of these controversially branded products helps to construct attitudes about these subjects and demonstrates a societal acceptance of these as norms. The British Empire Marketing Board (EMB) represents an important historical example of the production of such racialized values. Between 1926 and 1933, the EMB created and disseminated marketing materials to promote intra-Empire trade. While the EMB was generally considered to …

Very Young Child Survivors Of Parent Suicide: Perspectives On Children's Literature For Bibliotherapy, Cortland L. Watson

Theses and Dissertations

The death of a parent by suicide is especially traumatic. Researchers estimate the number of children in the United States annually who experience their parent's suicide ranges from 7,000 to 30,000. These child survivors experience more complicated grief as compared to children bereaved by a parent's non-suicidal death. In particular, very young children have difficulty understanding that their parent completed suicide. Across time they struggle with confusion and intense emotions associated with their parent's suicide. Due to the stigma associated with suicide, feelings of guilt, and intense grief, surviving family members avoid talking about the suicide. Young children are often …

Effects Of Genipin Crosslinking On The Properties Of Tendon Derived Extracellular Matrix Hydrogels, Alicia Cheyenne Coombs

Theses and Dissertations

Extracellular matrix (ECM) hydrogels are a useful biomaterial in the tissue engineering field used for injectables in drug delivery systems, wound dressing, tissue regeneration and many other applications. ECM hydrogels are highly biocompatible, contain proper ratios of biomolecules required for complex bioactivity of tissues and they promote tissue repair. However, ECM hydrogels typically have poor mechanical strength, which leads to hydrogel instability, and a limitation in their ability to be modified for translational applications. In this research, genipin, a natural crosslinker derived from plants, was utilized in an attempt to improve upon the mechanical limitations of ECM hydrogels. Genipin has …

Brand Activism And Gender: Nike As A Case Study, Kirsten Rasmussen

Natural Nitrate Removal In Shallow Subsurface Stream Flows, Abigail Heath

Theses and Dissertations

As agricultural growth increases across the planet, more anthropogenic nitrate from fertilizers and sewage effluent is contributed to the aquatic system, exacerbating both ecosystemand human-health issues. Nitrate is naturally processed and removed within the environment, and those processes have been observed in a segment of substrata and porewater below streams called the hyporheic zone (HZ). The interaction of stream water with groundwater can promote denitrification; however, the rate of nitrate removal within the HZ is unknown. This study determined the extent of surface water-groundwater interactions in a HZ and assessed the nitrate as nitrogen removal in this zone via monthly …

Investigating The Role Video Game Players’ Supportive Communication Plays In Moderating The Effects Of Toxicity In Online Gaming, Duy Pham

Theses and Dissertations

Online video games are perceived as a hostile space that welcomes aggression and verbal abuse based on biological sex, gender, race, and sexual orientation. Therefore, video game players may choose to communicate in a supportive fashion toward other players or engage in toxic behaviors due to increased aggression and masculine norms. While scholars have been investigating supportive messages in a computer-mediated context, past research inquiries into supportive communication and video gaming have remained separate. The present study will connect these disparate lines of research. This study explores different levels of verbal person-centeredness (VPC) of support messages, combined with the sex …

Appropriation Of The Highest Order: A Study Of Harry Smith’S Master Work, Film No. 18 Mahagonny In Relation To The Brecht-Weill Opera The Rise And Fall Of The City Of Mahagonny And Duchamp’S The Large Glass, Rose V. Marcus

Theses and Dissertations

Harry Smith’s Film No. 18, Mahagonny, 1970 – 1980, is a transmutation of the original Brecht-Weill opera, The Rise and Fall of the City of Mahagonny, a 1930, into a feature-length experimental film. This paper shows how the original opera and Duchamp's The Large Glass prove inherent to Smith’s double-pronged homage to both original works of art. The failure in the opera narrative and the chance shattering of The Large Glass inform Smith’s complex methodology to approach and spatialize cinema. Harry Smith’s use of the tools of the screening apparatus are traced in order to study Mahagonny in detail. The …
