Development Of An In Vitro Three-Dimensional Breast Tissue Model To Decipher The Effects Of Stromal Heterogeneity On Normal And Cancerous Mammary Epithelial Cells, Erin Mccave

All Dissertations

A goal of breast cancer research is to develop a detailed understanding of the underlying mechanisms of disease progression and to generate approaches to improve early detection, monitoring, and treatment of breast cancerous lesions. Current breast cancer therapies are not successful for all cases as they were developed as a standard of care for 'average' breast cancer condition. To further current clinical success, the characteristics of each tumor mass must be considered. Such an individualized or personalized approach is incompatible with current understanding of 'average' breast cancer tumors and responses to treatments. The long-term objective of the present research is …

Associations Between Travel Behavior And The Academic Performance Of University Students, Qianying Wu Dec 2014

Associations Between Travel Behavior And The Academic Performance Of University Students, Qianying Wu

All Theses

Purpose: Different travel behavior, particularly the choice of commuting modes, will have different impacts on students. On one hand, it has been suggested that active commuting (walking, cycling, and taking transit) will add routine daily exercise. Moreover, health benefits (improved cognitive function and reduced anxiety) from physical activity might increase students' academic performance. Nevertheless, too much physical activity may reduce the time for students to study. Travel time may shorten study time, and study time has been identified as positively contributing to academic performance. Considering that there is limited research examining travel behavior and academic achievement of university students, this …

Popular American News Media Explained Through Visual Arts: Using Drawing As A Tool For Humorous And Obligatory Cultural Critique, Joel Murray Dec 2014

Popular American News Media Explained Through Visual Arts: Using Drawing As A Tool For Humorous And Obligatory Cultural Critique, Joel Murray

All Theses

Through my drawings, I focus on jostling the passive American viewer out of her/his complacent acceptance of the images delivered by popular media outlets. Using humor as a multi-functional tool, I combine and reinterpret recognizable media artifacts to comment on the content that makes up American culture. This body of work is a cultural critique, pitting the ridiculous and superficial entertainment we (Americans) so easily ingest against current and crucial moments in time (i.e: political protests, violence, death, etc). Often times, the current media landscape is saturated with fast-cycling images and stories that do not promote careful contemplation. Instead, these …

What Adds Up To Being: The Work Of Tanna Burchinal, Tanna L. Burchinal Dec 2014

What Adds Up To Being: The Work Of Tanna Burchinal, Tanna L. Burchinal

All Theses

My practice takes form around embodied experience. I affect signifiers of the human body within the ordered grid, the scientific text, and the logic of the machine, to highlight the interdependencies of physical bodies and those social constructs that produce and influence identity. We are a part of these constructs that both extend and limit; we are enacting and interacting with them. I do not aim to eradicate these structures of power (without them, our identities are in chaos). Instead, I point out the pitfalls of these constructs that are perceived as unchanging, by making interaction and experience integral to …

Manifest Complexity: A Foundational Ethic For Astrobiology?, Kelly C. Smith Nov 2014

Manifest Complexity: A Foundational Ethic For Astrobiology?, Kelly C. Smith

Publications

This paper examines the age old question of the basis of moral value in the new context of astrobiology, which offers a fresh perspective. The goal is to offer the broad outline of a general theory of moral value that can accommodate the diversity of living entities we are likely to encounter beyond the confines of Earth. It begins with ratiocentrism, the view that the possession of reason is the primary means by which we differentiate entities having moral value in and of themselves from those having moral value merely by virtue of the uses to which they can be …

Post-Hurricane Fuel Dynamics And Forest Regeneration Of Coastal Pine Stands In Southeast United States, Shanyue Guan Nov 2014

Post-Hurricane Fuel Dynamics And Forest Regeneration Of Coastal Pine Stands In Southeast United States, Shanyue Guan

All Theses

Hurricanes have long been powerful and recurring disturbances in many coastal forest ecosystems. Intense hurricanes often produce a large amount of dead fuels within their affected forests, but how post-hurricane fuel complex changes with time, due to decomposition and management such as salvage, and the fire behavior affected by the changed fuel load remains largely unknown. To better understand the fuel and regeneration dynamics, field measurement and modeling were conducted within undamaged stands and hurricane damaged stands, including salvaged and unsalvaged stands in southern pine forests impacted by hurricane Hugo (1989), Opal (1995), Katrina (2005), and Ike (2008). We found …
