Comparison Of Rip And Rcp Conditioning Procedures On Vocalizations In Children With Autism And Minimal Echoic Repertoire, Jacqueline Pecoraro
Theses
Pairing procedures have been utilized by researchers and in applied practice for many years to establish neutral stimuli as conditioned reinforcers. Recently, pairing procedures, specifically stimulus-stimulus pairing, have been applied to vocalizations. Vocalizations are an essential element for language development because once vocalizations are brought under echoic control, they can be used to further develop a child’s verbal behavior. Results of the research conducted on stimulus-stimulus pairing had varied results, and the effectiveness of stimulus-stimulus pairing on increasing vocalizations is uncertain. Lepper and Petursdottir (2017) conducted a study that compared traditional stimulus-stimulus pairing (or response-independent pairing (RIP)) to response-contingent pairing …

Attentional Alchemy: Crafting Meaning In The Fabric Of Experience ---An Argument From Attention For The Content View, Ling 鳕鱼 张 Zhang
Theses
Abstract: In the realm of philosophy of mind, a central inquiry concerns whether perceptual experiences have content. This paper aims to construct an argument, termed Argument from Attention, which asserts that all visual experiences have content in the minimal sense, drawing upon insights from phenomenological features of attentional experience and mechanisms of attention elucidated in The Erotetic Theory of Attention. To achieve this goal, the paper begins by clarifying the essential features of contentful experience in Section 2. Furthermore, the second subsection scrutinizes Siegel's Argument from Appearances, highlighting the susceptibility of her Weak Content View to the …
Atoms And Leaves, Patty Tomanovich
Atoms And Leaves, Patty Tomanovich
Theses
Atoms and Leaves is a photographic project presented as windows into a utopia. The glass images display a potential time and place where the landscape, photography, and transness intertwine and grow from each other. Photography historically harms the landscape- requiring precious metals, releasing pollution into the atmosphere, and creating hazardous water waste. The traditional photographic canon erases the connection between queerness and ecology. Atoms and Leaves rethreads these connections, creating a world where photography collaborates with the landscape and takes on a transgender perspective by reshaping given material. The photographic printing process developed in this project was inspired by the …

Block Copolymers And Chirality: Interplay Between Conformations And Structures, Natalie Buchanan
Block Copolymers And Chirality: Interplay Between Conformations And Structures, Natalie Buchanan
Theses
Block copolymers can exhibit chirality at three different length scales – molecular chirality at the residue scale, conformational chirality at the molecular scale, and structural chirality at the mesoscale from the self-assembly of thousands of molecules. Unique morphologies have been formed due to chirality transfer, a phenomenon where chirality at smaller length scales imparts chirality to larger length scales. However, chirality does not always transfer, with chiral blocks existing in an achiral phase due to chiral frustration. The thermodynamics of the effects of chirality on block copolymer self-assembly is not well understood. This work demonstrates that coarse-grained models can effectively …
Advancements In Scanning Electron Microscopy, Surya Kamal
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
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
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 …
