On Thomson's Normativity, Michael James Vossen
On Thomson's Normativity, Michael James Vossen
Theses
Are non-attributive uses of ‘good’ meaningful? Judith Jarvis Thomson, in her book, Normativity, argues that such uses are not. I argue that Thomson is mistaken, but in a way which improves on her basic account of the evaluative and directive judgments central to normative thought. Relations among kinds, and not just relations between kinds and individuals, can be understood as ethically relevant. Such kind-kind relations can provide a semantic basis for non-attributive uses of good. Accounting for such non-attributive uses allows Thomson to address three significant problems with her account. First, this account allows Thomson to make a more nuanced …
Alien Attributions And The Possibility Of Missing The Mark: A Critique Of Velleman's Account Of Autonomy And The Constitutive Aim Of Action, Matthew Todd Flummer
Alien Attributions And The Possibility Of Missing The Mark: A Critique Of Velleman's Account Of Autonomy And The Constitutive Aim Of Action, Matthew Todd Flummer
Theses
David Velleman has argued that action has a constitutive aim. This constitutive aim is analogous to the constitutive aim of belief. The constitutive aim of belief, he argues, is to track the truth or arrive at the truth. This aim sets the standard of correctness for a belief. A belief is correct if and only if it is true. So reasons for belief are considerations that point toward truth either by guaranteeing truth or significantly raising the probability of the truth. Any belief that fails to track the truth misses the mark set by the constitutive aim of belief. Like …
Shakespeare Wrote No Characters, Alexander Patrick Detmering
Shakespeare Wrote No Characters, Alexander Patrick Detmering
Theses
The purpose of my research was to answer a simple question: “What can be said about Hamlet's character?” When analyzing any Shakespearean play, it is commonplace to begin (and end) with the characters that inhabit it. But is this sort of analysis appropriate for Renaissance plays? Freud's famous interpretation of Hamlet operates in this fashion, determining the meaning of the play through the vehicle of Hamlet's character—specifically, the psychology of Hamlet's character. Such a reading assumes, however, the interiority of character: that fictional characters have mental landscapes, complete with pasts that lead to the present as related in the events …
The Relationship Between Self-Reported Strength Of Parasocial Interaction And Perception Of World Stability, Rachel Provenzano
The Relationship Between Self-Reported Strength Of Parasocial Interaction And Perception Of World Stability, Rachel Provenzano
Theses
This study investigates parasocial relationships, uncertainty, and need for orientation. Respondents' strength of parasocial relationship was gathered using an adapted version of Auter and Palmgreen's (2000) Audience-Persona Interaction Scale. Respondents' perception of world stability was comprised of level of uncertainty and need for orientation, both measured using a scale created for the present study. Results showed a positive correlation between respondents' strength of parasocial relationship and level of uncertainty and a significant difference between respondents with high and low levels of parasocial interaction and need for orientation. However, no significant differences were found to exist between respondents with high and …

Environmental Impact Analysis Of Alternative Pallet Management Systems, Ainoa Mazeika Bilbao
Environmental Impact Analysis Of Alternative Pallet Management Systems, Ainoa Mazeika Bilbao
Theses
Pallets, the most common unit-load platform, allow the transportation of goods in an efficient and reliable way. Every year, 700 million new pallets are manufactured and become part of the approximately 2 billion pallets that are in circulation in the U.S. The total life-cycle environmental impact of pallets depends on materials, manufacturing, handling processes, and the disposal practice (end-of-life). Plastic pallets can be lighter and might last longer but their manufacturing processes are energy intensive and could contribute significantly to greenhouse gas (GHG) emissions. On the other hand, wooden pallets can be cheaper and easily repaired but present a shorter …

Sculptural Life Forms, Jaiik Lee
Sculptural Life Forms, Jaiik Lee
Theses
The purpose of my art is to express the mystery of life. Through the shaping of material mass, I induce my work to influence space and time in an attempt to discover special meaning about the life phenomenon of all creatures from the beginning of time to their present manifestations today. The origin of life has been the subject of numerous debates including those pitting creationism against evolution and churchmen against scientists. There remain, however, discoveries and artifacts like ancient fish fossils, that connect features of our humans ancestors with other living organisms. Perhaps this is a riddle that will …
An Unnatural History, Sarah Hearn
An Unnatural History, Sarah Hearn
Theses
An Unnatural History is an installation that inhabits the space between the continuously shifting realms of science, pseudoscience and science fiction. This project documents the (fictional) discovery of a taxonomy of marine life containing and cooperating with the elements from the periodic table. As science and technology progress, we are constantly faced with redefining, reinterpreting and reconfiguring what we thought we knew about the world around us and previous scientific "facts" are revealed to have been constructed "beliefs." Using multiple modes of representation, An Unnatural History draws attention to the real, the imagined and what it means to visualize biological …
Sola In Nature, Yeonhee Choi
Sola In Nature, Yeonhee Choi
Theses
Sola in Nature is an invitation to encounter the internal human experience inspired by nature. Each photograph exhibits different sensibilities; exploring what the psychological self represents in nature through the images. The human mind is like air. We cannot smell, hold, and see the air, but we can feel it when we breathe. We cannot live without it. This thesis transcribes personal experience into a photographic spectacle that provides the public access, with which to examine the sophisticated mind as reflection of the self. Nature is, in this work, considered not only as spiritual existence but also as the psychological …
Effects Of Hypertension And Aging On Vascular Smooth Muscle Cell Contribution To Reconstituted Aortic Tissue Stiffness, Nancy Lisa Sehgel
Effects Of Hypertension And Aging On Vascular Smooth Muscle Cell Contribution To Reconstituted Aortic Tissue Stiffness, Nancy Lisa Sehgel
Theses
Aortic stiffness increases with hypertension and aging, and much of this increase has been thought to occur due to changes in the extracellular matrix. However, an increase in cell stiffness could also be important. To study the cellular contribution to aortic stiffness, a reconstituted aortic tissue model (composed of vascular smooth muscle cells (VSMCs) in a collagen matrix) was developed. VSMCs isolated from thoracic aortic samples of 5-week and 18-week old male spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto (WKY) rats were passaged four times and then separately incubated in collagen for two days on a cylindrical mandrel. The resulting …

Evaluation Of Rice Extract As A Potential Stabilizer In Plain Yogurt, Sangeetha Nurani Viswanathan
Evaluation Of Rice Extract As A Potential Stabilizer In Plain Yogurt, Sangeetha Nurani Viswanathan
Theses
Quality and consumer acceptability are essential parameters in dairy products The objectives of the present study were to examine the microbiological (viability of L. bulgaricus, S. thermophilus, and bifidobacteria), chemical (pH, titratable acidity, and total solids), and physical(syneresis) qualities of yogurt enriched with rice extract as a stabilizer during 28 days of storage at 4°C. Additionally, viscosity measurements and consumer acceptability were determined for yogurt enriched with rice extract. Results showed that the viability of L. bulgaricus was maintained with the addition of rice extract. Population of Streptococcus thermophilus and bifidobacteria decreased significantly (p<0.05) in the control sample but the addition of rice extract at 15% concentration supported the viability of bifidobacteria in yogurt over storage. The addition of rice extract did not alter the pH or titratable acidity of yogurt. Viscosity, total solids and syneresis values slightly changed with the addition of rice extract. Yogurt prepared with rice extract ranked higher in terms of texture and appearance by the panelists. Our results indicated that the addition of rice extract could improve the quality characteristics and consumer acceptability of plain yogurt. Hence, rice extract has a promising potential to be used as an alternative stabilizer in dairy products.

High Resolution Hybrid Mass Spectrometry For The Determination Of Marine Biotoxins, Azaspiracids, And Their Biotransformation Products., Zuzana Skrabakova
Theses
Azaspiracids (AZAs), polyether marine toxins, are produced by marine microalgae and accumulate in filter-feeding bivalve molluscs, such as mussels, clams, oysters and scallops, while grazing on phytoplankton, from which they derive nutrition. Although being discovered quite recently, AZAs have caused several human intoxication events and thus became a problem for health authorities and shellfish industries. The rapid development of highly sensitive liquid chromatography multiple tandem mass spectrometry (LC-MS/MS, LC-MS") methods enabled the identification of numerous AZA analogues and added to the control of shellfish contamination. Tandem mass spectrometry techniques, while being highly selective and sensitive for determination of AZAs in …
