Advancements In Scanning Electron Microscopy, Surya Kamal

Theses

Scanning electron microscopes (SEM) are poorly characterized imaging instruments. The SEM optics (lens and aperture assembly) is designed to form a focused electron probe that scans the specimen to produce images. Therefore, the imaging efficacy in SEM strongly depends on the quality of the optics. However, there is no way to accurately characterize the optics in an uncorrected SEM (without multipole correctors) due to the lack of an exit wave. This work focuses on improving the imaging capabilities of an uncorrected SEM by understanding its optical performance using wave optical theory, simulation, and experiment. In this dissertation, we have developed …

The Normativity Of Social Role Concepts, Robert Laurent Iii

Theses

This paper argues that social role concepts are both descriptive and normative. A "social role concept" is any concept that describes a person’s station in life from the point of view of society as a whole. Social roles are usually positions into which one is born and which are difficult if not impossible to renounce from within the conceptual system. Social roles are therefore not mere jobs or descriptions. They place certain obligations upon a person that are meant to apply absolutely. This paper first discusses the normativity of rule-governed practices and the rules involved in concept use. The paper …

An Egalitarian Approach To Explanations In Mental Disorders, Eli Driskill

Theses

Explanations of mental disorders come from a wide array of disciplines and epistemologies. How we conceive of and order these explanations has great importance for agency. Yet, psychiatry as a discipline has long suffered from the assumption that these explanations are multi-level. That is, some lower-level mechanism (i.e. neurobiology) constrains the information produced at a higher-level behavior. I argue that this approach is unsatisfying, and offer a new perspective: the egalitarian approach to mental disorders. The egalitarian model of mental disorders is non-hierarchical, dynamic, and cross-cultural. The paper begins by highlighting an inherent feature of psychiatry which I coin the …

American Absurd, Kelly Stolle

Theses

There is perhaps one line that separates the American mindset from all others in the world. That is the fascination with the American Dream. This dream, having existed since the creation of this nation, has guided almost all developments we have seen it undertake. The question that lingers, however, is what this “American Dream” actually is. How does one interpret freedom? Further, what is one to do with it? This work suggests that what fuels the American Dream is an absurdist philosophy that ripples through every aspect of American life. Utilizing the modernist literary movement, I will analyze 6 key …

Addicted To The Beloved? A Comparison Of Craving For And Attention To Beloved And Vape Stimuli, Caitlyn Harriman

Theses

People who are in love seem to be addicted to their beloved. People who are in love have attentional biases for the beloved and people who are addicted have attentional biases for the substance they are using. This raises the question of how similar craving and attention are for the beloved and an addictive substance. However, there are no studies that directly compared craving and attention to the beloved and addictive stimuli. The aims of the current research were to directly compare subjective emotional experiences, sustained motivated attention, and early automatic attention for the beloved and vape stimuli, in people …

On Learning Your Gender: A Comprehensive View, Audra M. Hazelwood

Theses

This essay provides a metaphysical and epistemological account of gender. The metaphysics involves a ‘non-reductionist view of gender’, which is to say that gender cannot be reduced to a single factor. On this view gender begins with one’s innate gender inclinations (in the vein of Julia Serano). These inclinations pick out a specific range of gender possibilities from the gender spectrum that apply to a person. At the same time we live in communities and cultures with certain gender norms. This is where epistemology comes into play since our gender inclinations are filtered through gender norms and some people are …

Towards Erasing The Distinction Between The Computational And Syntactic Accounts Of Scientific Theories, Timothy Luft

Theses

One of the main goals of philosophy of science is to give a proper account of scientific theories and their structure. One way that accounts of the structure of scientific theories can be distinguished is by the mathematical or logical structures that they involve. For instance, syntactic accounts of scientific theories hold that theories are axioms in a logical framework, whereas semantic accounts are more liberal in the range of mathematical and logical structures they take as pertinent to the structure of scientific theories. Paul Thagard (1988) offers a computational account of scientific theories, which holds that theories are complex …

Between Fodor And Sellars -- A Middle Ground For Language-Like Neural Representations, Hanzhe Dong

Theses

The recent resurgence of the language of thought (LOT) hypothesis has drawn much attention. The history of philosophy and cognitive science has provided us with various versions of LOT. From Sellars to Fodor, theorists have offered us considerations on the vehicles, content, and functions of such a representation format. However, it’s been more than 50 years since Fodor’s publication on LOT (1975), and the resurgence suggests that we need a modern iteration of LOT to fit with recent developments in the study on cognition. Therefore, in this paper, I argue that we need a middle ground between Fodor and Sellars’s …

A New Vicarious Technique For Radiometric And Spatial Calibration Of Drone-Based Multispectral And Hyperspectral Imaging Systems, David N. Conran

Controlling The Narrative: The Effects Of Media Coverage On Fear Of Crime And Socio-Political Ideology, Andrew Koppelman

Theses

Several decades of study have established an understanding that media have a unique power to influence the perspectives and worldviews of audiences. This phenomenon has been explored through the lenses of Social Learning and Cultivation theory, wherein media appeal to base human tendencies of self-preservation and teaches audiences how to maximize rewards for their actions by acting as a sort of instructor or friendly warning from members of the community. While prior studies have suggested the presence of this effect, little research has been devoted to understanding the ways that this may influence behaviors in viewers. My research seeks to …

Xenopus laevis is a standard model for developmental toxicity due to being minimal maintenance, cost efficient, and having transparent embryos. Xenopus makes …

An Evaluation Of The Teach-Back Method For Training Functional Analysis Methodology, Bethany Christie

Theses

Behavior analysts conduct functional analyses to identify the environmental contingencies maintaining challenging behavior, which allows them to develop a function-based treatment plan. Behavioral staff must be fully trained on functional analysis methodology before conducting the analysis. A common way to train staff to conduct a functional analysis is through behavioral skills training (BST), but BST is time consuming and includes numerous materials. Teach-back, a widely used training method in healthcare settings, requires less time and no materials. Currently, there is little research on the effectiveness of the teach-back method for teaching behavioral techniques, and there is no research on the …
