Maternal Subjectivities In The 18th And 19th Century British Novel, Anastasia Vahaviolos Valassis

Dissertations, Theses, and Capstone Projects

How is the maternal subjectivity narrated in the pages of the 18th and 19th century British novel? This dissertation examines this question. The novel’s close connection to the child’s subjectivity and perspective is something woven into its very fabric, and so the mother is often a side character, an object in the story. She is an obstacle to be overcome, a distant idea, an absent figure, or even someone too perfect to be represented on the page. The novel often reflects or mirrors this culturally and psychologically accepted way of viewing the mother. The tracing of the narratives in which …

Timbres Oubliés: The Forgotten Sounds Of Loeffler's Octet, Graeme Steele Johnson

Dissertations, Theses, and Capstone Projects

Modern musicians play a lot of old music and a lot of new music, but not so much “new old music.” This study—with its accompanying critical edition score, world-premiere recording and first present-day performances—represents, at long last, the deliverance of one such work from the ashes of history to the ears of the present: Charles Martin Loeffler’s forgotten Octet for Two Clarinets, Harp, Two Violins, Viola, Cello and Double Bass, a piece that was left unpublished, unrecorded and unheard since 1897.

This paper documents my efforts to finally reintroduce the Octet to the repertoire. By cross-referencing the autograph manuscript score …

Relationship Interventions For Autistic Children And Their Non-Autistic Siblings, Susan Vanessa Mchugh

Dissertations, Theses, and Capstone Projects

Relationships between children with autism and their non-autistic siblings are often characterized by great warmth, empathy, and affection. However, because of core deficits in social-emotional reciprocity, autistic children and their siblings often experience difficulties with communication, play, and associated mental health problems. Interventions aimed at improving relationships in these sibling dyads historically have involved teaching non-autistic children to behave similarly to interventionists for autistic siblings, and support groups for children with broad chronic illnesses. More recent interventions have shifted focus to improvement of play between siblings, and support groups for siblings of children with autism spectrum disorder. Some are naturalistic …

Exploiting The Heavy Chain Glycans For The Improvement Of Radioimmunoconjugates, Cindy Rodriguez

Dissertations, Theses, and Capstone Projects

Radiolabeled antibodies have become indispensable tools in nuclear medicine. However, the natural roles of antibodies within the immune system mean that they have several intrinsic limitations as a platform for radiopharmaceuticals. A handful of recent preclinical studies suggest that binding by FcR and particularly FcyRI can affect the pharmacokinetic profiles of 89Zr-labeled radioimmunoconjugates. Fc receptors (FcR) are responsible for many of the interactions between immunoglobulins (IgG) and immune cells. In biomedicine, this interplay is critical to the activity of several types of immunotherapeutics; however, relatively little is known about how FcRs affect the in vivo performance of radiolabeled antibodies. Antibodies …

Essays In Health Economics And Applied Econometrics: Assessing Recreational Marijuana Laws, Dragos Ailoae

Dissertations, Theses, and Capstone Projects

This dissertation explores the diffusion and impacts of state recreational marijuana laws (RML). Chapter 1 examines factors driving state adoption and spread of RML, finding that states with citizen ballot initiatives, expansive legislative capacities, and higher fiscal stress are more likely to enact RML. Ideological proximity, rather than geography, drives policy diffusion, with learning from early adopters likely serving as a key mechanism in the process. Chapter 2 assesses first-order effects of RML on marijuana consumption and drug policing using various econometric methods. Results suggest amplification bias in difference-in-differences point estimates due to an endogenous policy variable. This has economic …

On-Grid Optimal Mppt For Fine-Tuned Inverter Based Pv System Using Golf Optimizer Considering Partial Shading Effect, Mohammed Hassan El-Banna, Muhammad R. Hammad, Ashraf Ibrahim Megahed, Kareem M. Aboras

Open Access archive

Improving photovoltaic systems to better withstand variations in temperature and irradiance, lessen steady-state ripples, maintain high efficiency, require less tracking time, and have minimal complexity is becoming increasingly important. The PV array's overall power output is negatively impacted by partial shading because the shaded cells produce less power and consume less power overall, which lowers efficiency and creates localized hotspots. Although bypass diodes may be used to counteract these impacts by rerouting current around cells that are shaded, they can result in several peaks, which complicates maximum power point tracking (MPPT). To manage several peaks and optimize power output, metaheuristic …
