Examining the Role of Latitude and Differential Insolation in Asymmetrical Valley Development

Description: Valley development through erosional processes typically tends to create symmetrical valleys. Over time, water cuts through the substrate to create valleys, gorges, and canyons for which the sides are the valley are evenly sloped. However, there are anomalies to this process. Asymmetrical valleys have been well-documented even in areas of uniform substrate or little tectonic uplift. One proposed explanation for the asymmetry of these valleys is differential insolation. This may lead to diff… more

The Ideological Appropriation of La Malinche in Mexican and Chicano Literature

Description: La Malinche is one of the most controversial figures in Mexican and Chicano literature. The historical facts about her life before and after the Spanish Conquest are largely speculative. What is reliably known is that she had a significant role as translator, which developed into something of mythic proportions. The ideological appropriation of her image by three authors, Octavio Paz, Laura Esquivel and Cherríe Moraga, are explored in this thesis. The full extent of the proposed rendition of L… more

Cold-formed Steel Framed Shear Wall Sheathed with Corrugated Sheet Steel

Description: Incombustibility is one important advantage of the sheet steel sheathed shear wall over wood panel sheathed shear wall. Compared to shear wall sheathed with plywood and OSB panel, shear wall sheathed with flat sheet steel behaved lower shear strength. Although shear wall sheathed with corrugated sheet steel exhibited high nominal strength and high stiffness, the shear wall usually behaved lower ductility resulting from brittle failure at the connection between the sheathing to frames.

The Ways of Reflection: Heidegger, Science, Reflection, and Critical Interdisciplinarity

Description: This thesis argues that there is a philosophical attempt directed at combating the fragmentation of the sciences that starts with Heidegger and continues today through Trish Glazebrook's interpretations of the former's concept of "reflection," and Carl Mitcham and Robert Frodeman's concept of "critical interdisciplinarity" (CID). This is important as the sciences are both more implicated in our lives and more fragmented than ever. While scientific knowledge is pursued for its own sake, the pe… more
