The Role Of Imperfection In Everyday Aesthetics, Yuriko Saito

Contemporary Aesthetics (Journal Archive)

The notions of perfection and imperfection do not have the same prominent presence they once occupied in earlier aesthetics discourse. However, they still play an important role as criteria for aesthetic judgments today in our everyday life. The wide-spread and easily accepted aesthetic appeal of objects with perfection tends to overshadow the potential aesthetic value of imperfect objects that are considered to be defective or deficient. This not only impoverishes our aesthetic lives but also leads to some serious environmental and social consequences. I first argue for the need to cultivate an aesthetic sensibility to appreciate imperfection in our everyday …

Bio-Aesthetics: The Evolution Of Sensibility Through Nature, Katya Mandoki

Contemporary Aesthetics (Journal Archive)

[1] This paper gathers a few points developed in my recent book, The Indispensable Excess of the Aesthetic: Evolution of Sensibility in Nature, where I explore the processes that involve aisthesis from their most primal manifestations to their more complex. I propose the concept of bio-aesthetics as the study of all forms of sensibility in living beings, and that, given the fact that it is a function of our corporeal condition, the required starting point is the evolutionary paradigm. Another crucial tool for understanding how different types of creatures value, understand, react, and relate to their environment is provided by …

Investigating The Utility Of Video Modeling Interventions For Generalization Of Social Skills, Laura Ambrose

Graduate Student Theses, Dissertations, & Professional Papers

Social skill deficits are a core, defining feature of Autism Spectrum Disorder. As such, many of the available interventions for children and youth with autism are designed to target social skill development. Although many of these interventions purport to be an effective means of teaching social skills to children and youth with autism, many are lacking in empirical evidence and do not satisfy criteria for evidence-based practice. Encouragingly, video modeling interventions have been deemed an evidence-based practice for children and youth with autism. Research demonstrates that video modeling interventions can prove an effective means for the generalization of skills, a …

Aerodynamics And Ecomorphology Of Flexible Feathers And Morphing Bird Wings, Brett Klassen Van Oorschot

Graduate Student Theses, Dissertations, & Professional Papers

Birds morph their wings during a single wingbeat, across flight speeds, and among flight modes. Such morphing may allow them to maximize aerodynamic performance, but this assumption remains largely untested. We tested the aerodynamic performance of swept and extended wing postures of 13 raptor species in three families (Accipitridae, Falconidae, and Strigidae) using a propeller model to emulate mid-downstroke of flapping during takeoff and a wind tunnel to emulate gliding. Based on previous research, we hypothesized that 1) during flapping, wing posture would not affect maximum ratios of vertical and horizontal force coefficients (CV:CH), and that 2) extended wings would …

The Business Of Empire: American Capitalists, The Nicaraguan Canal, And The Monroe Doctrine, 1849-1858, Jonathan D. Del Buono

Graduate Student Theses, Dissertations, & Professional Papers

In the mid-nineteenth century, U.S. policymakers designed foreign policy to enhance the reach of American commerce and create a commercial empire in and through Latin America. To create this empire U.S policymakers wanted to construct a canal through Central America, which they envisioned as a joint enterprise between American businesses and the federal government. In 1849, Cornelius Vanderbilt and his associates reserved a charter from the Nicaraguan government to build and operate a canal and transit route through their county. Yet competition between varied business interests prompted the U.S. destruction of the Nicaraguan port city of San Juan del Norte …

Epistemically Detrimental Dissent In Climate Science, Iheanyi Amadi

Graduate Student Theses, Dissertations, & Professional Papers

Dissent, criticism and controversy are integral to scientific practice, especially when we consider science as a communal enterprise. However, not every form of dissent is acceptable in science. The aim of this paper is to characterize what constitutes the kind of dissent that impedes the growth of knowledge, in other words epistemically detrimental dissent (EDD), and apply that analysis to climate science. I argue that the intrusion of non-epistemic considerations is inescapable in climate science and other policy-relevant sciences. As such there is the need to look beyond the presence of non-epistemic factors (such as non-epistemic risks and economic interests) …

Enclosed From All Sides: Reading Contact And Ambivalence In The Imaginary Al-Andalus Of Hrotsvit's The Passion Of Pelagius And The Song Of Roland, Briana J. Wipf

Graduate Student Theses, Dissertations, & Professional Papers

Hrotsvit of Gandersheim’s The Passion of Pelagius and The Song of Roland have never been read together in terms of their shared engagement with the Muslim other in the Iberian Peninsula, known during the Middle Ages as Al-Andalus. This project is a comparative reading of the texts’ approach to the presentation of an imaginary Al-Andalus as a space of alterity. The texts’ emphasis on imaginative as opposed to accurate portrayals of Andalusian history and Islamic culture suggests their engagement with a process of Christian identity-building, where the “Christian,” as portrayed in each text, is defined against and in comparison to …
