This dissertation aims to: 1) characterize the range of beliefs museum practitioners have about racial, ethnic, and cultural diversity; 2) their understanding of the role of race, culture, and ethnicity in minoritized learners’ sensemaking; and 3) the areas of tension and symmetry between practitioners’ values and their perception of their...
The dissertation aims to explore the intersection between the artistic performance of blackness in contemporary Italian theater and the country's social stigmatization of black immigrants as a problem or national emergency. I argue that Italians live in a state of "historic forgetfulness" since they have not been able to absorb...
Peptide Amphiphile (PA) molecules developed in the author's laboratory and others have shown great versatility in creating self-assembled nanostructures with built-in biological and/or chemical functionalities. Their applications in spinal cord injury repair, angiogenesis, promoting cell adhesion and templating inorganic materials have also been well studied. Complementing previous compositional studies, where...
PRC is a PGC-1 coactivator family member responsive to serum growth factors and up regulated in proliferating cells. Unlike PGC-1α and PGC-1β, PRC has not been studied extensively and and its function or regulation remains largely unknown. Both PGC-1α and PGC-1β have been shown to be important regulators of mitochondrial...
<span style="font-family: Calibri;">BaNa-Y is a catalyst for reduction of nitrogen oxides (NO and NO<sub>2</sub>) with added reductants at temperatures of ~200 °C. Studies were performed over BaNa-Y and related catalysts to unravel the roles that nitrates and nitrites play in determining the processes and pathways involved in NOx reduction. <o:p></o:p></span></p>...
Although cementitious construction materials are mainly used in a large scale and in huge quantities, fundamental properties such as strength, ductility, creep, shrinkage, and fracture behavior depend, to a great extent, on structural elements and phenomena which are effective at the micro- and nanoscale. This research involves characterization of the...
An integral transform which reproduces a transformable input function after a finite number $N$ of successive applications is known as a {\it cyclic} transform. Of course, such a transform will reproduce an arbitrary transformable input after $N$ applications, but it also admits eigenfunction inputs which will be reproduced after a...
Modern-day middle school science textbooks are heavily populated with colorful images, technical diagrams, and other forms of visual representations. These representations are commonly perceived by educators to be useful aids to support student learning of unfamiliar scientific ideas. However, as the number of representations in science textbooks has seemingly increased...
Sleep deprivation (Sd) preferentially impairs predictive and adaptive behaviors that shift responses based on the appropriate context. Behavioral studies implicate the frontal lobes as particularly susceptible to Sd. Aging also impairs frontal functioning, and alters the response to Sd. The interaction between age and Sd is poorly understood, and few...
In this work several self-assembling PA systems containing covalent-linking functionalities have been investigated. These covalently linkable PAs were designed to probe the supramolecular structure by covalent capture of the nanofibers and also improve the mechanical stiffness of the gel-material. The diacetylene motif was the main functional group investigated because of...
