Cage's Imitation Game: Cheap Imitation And Song Books Through The Sketches, Jeffrey Perry

Faculty Publications

The theme of John Cage’s Song Books (1970), according to Cage, is contained in the statement “We connect Satie with Thoreau” (Cage 1970a, 1). Previous studies of Cage’s Song Books have not asked what I feel to be obvious questions: how, precisely, does Cage connect Satie with Thoreau? To what end? And how does Cage connect to Satie and Thoreau (and to the other sources from which he borrows)? I make use of Cage’s sketch materials to seek answers. I examine three of the Solos for Voice from Song Books that make use of the cheap-imitation procedure that Cage had …

On The Human Appropriation Of Wetland Primary Production, James A. Cloern, Samuel M. Safran, Lydia Smith Vaughn, April Robinson, Alison A. Whipple, Katharyn E. Boyer, Judith Z. Drexler, Robert J. Naiman, James L. Pinckney, Emily R. Howe, Elizabeth A. Canuel, J. Letitia Grenier

Humans are changing the Earth's surface at an accelerating pace, with significant consequences for ecosystems and their biodiversity. Landscape transformation has far-reaching implications including reduced net primary production (NPP) available to support ecosystems, reduced energy supplies to consumers, and disruption of ecosystem services such as carbon storage. Anthropogenic activities have reduced global NPP available to terrestrial ecosystems by nearly 25%, but the loss of NPP from wetland ecosystems is unknown. We used a simple approach to estimate aquatic NPP from measured habitat areas and habitat-specific areal productivity in the largest wetland complex on the USA west coast, comparing historical and …

Fourth-Order Adjoint Sensitivity And Uncertainty Analysis Of An Oecd/Nea Reactor Physics Benchmark: I. Computed Sensitivities, Ruixian Fang, Dan Gabriel Cacuci

Machine Learning Applied To K-Bentonite Geochemistry For Identification And Correlation: The Ordovician Hagan K-Bentonite Complex Case Study, Achim D. Herrmann, John T. Haynes, Richard M. Robinet, Norlene R. Emerson

Faculty Publications

Altered tephras (K-bentonites) are of great importance for calibration of the geologic time scale, for local, regional, and global correlations, and paleoenvironmental reconstructions. Thus, de-finitive identification of individual tephras is critical. Single crystal geochemistry has been used to differentiate tephra layers, and apatite is one of the phenocrysts commonly occurring in tephras that has been widely used. Here, we use existing and newly acquired analytical datasets (electron probe micro-analyzer [EPMA] data and laser ablation ICP-MS [LA-ICP-MS] data, respectively) of apatite in several Ordovician K-bentonites that were collected from localities about 1200 km apart (Minne-sota/Iowa/Wisconsin and Alabama, United States) to test …

Doran, Jill Mikucki, Hilary A. Dugan, Ricardo Garza-Giron, Krista Myers, Ross A. Virginia, Slawek Tulaczyk

Faculty Publications

Airborne electromagnetics (EM) is a geophysical tool well suited to mapping glacial and hydrogeological structures in polar environments. This non-invasive method offers significant spatial coverage without requiring access to the ground surface, enabling the mapping of geological units to hundreds of metres depth over highly varied terrain. This method shows great potential for large-scale surveys in polar environments, as common targets such as permafrost, ice and brine-rich groundwater systems in these settings can be easily differentiated because of their significant contrasts in electrical properties. This potential was highlighted in a 2011 airborne EM survey in the McMurdo Dry Valleys that …

Eye Movement Desensitization And Reprocessing (Emdr) Practitioners’ Beliefs About Memory, Sanne T.L. Houben, Henry Otgaar, Jeffrey Roelofs, Ineke Wessel, Lawrence Patihis, Harald Merckelbach

Faculty Publications

Eye movement desensitization and reprocessing (EMDR) is a widely used treatment for posttraumatic stress disorder. The idea behind EMDR is that lateral eye movements may mitigate the emotional impact of traumatic memories. Given the focus on changing patients’ memories, it is important that EMDR practitioners have detailed knowledge about human memory. We explored beliefs and ideas about memory in samples of EMDR practitioners (Study 1: n = 12; Study 2: n = 41), students (Study 1: n =35; Study 2: n = 24), and researchers (Study 2: n = 30).

Are The Dead Sea Scrolls From Khirbet Qumran?, Kenneth Atkinson

Faculty Publications

The Dead Sea Scrolls continue to remain the subject of an intense academic debate concerning their interpretation, their authors, and whether there is a connection between the caves in which these documents were discovered and the archaeological site of Khirbet Qumran. The answers to these questions are important because of the unprecedented number of fragmentary documents in this collection and their diverse contents. Because Roland de Vaux found the same types of pottery in the Scroll caves that he uncovered inside Khirbet Qumran, most scholars view the Scrolls as archaeological objects that are associated with this settlement. Khirbet Qumran’s architectural …

Data-Driven Algorithm To Classify The Degree Of Isotropy In The Bidirectional Reflectance Distribution Function, Anne W. Werkley, Samuel D. Butler, Todd V. Small, Michael A. Marciniak

Faculty Publications

The bidirectional reflectance distribution function (BRDF) is used to describe reflectances of materials by calculating the ratio of the reflected radiance to the incident irradiance. While it was found that the isotropic models maintained symmetry about ϕ_s  =  π, such symmetry was not maintained about the θ_s  =  θ_i axis, except for close to the specular peak. This led to the development of a data-driven metric for how isotropic a BRDF measurement is. Research efforts centered around developing an algorithm that could determine material anisotropy without having to fit to models. This algorithm was tested using high …

Robust Method Of Determining Microfacet Brdf Parameters In The Presence Of Noise Via Recursive Optimization, Michael W. Bishop, Samuel D. Butler, Michael A. Marciniak

Faculty Publications

Accurate bidirectional reflectance distribution function (BRDF) models are essential for computer graphics and remote sensing performance. The popular microfacet class of BRDF models is geometric-optics-based and computationally inexpensive. Fitting microfacet models to scatterometry measurements is a common yet challenging requirement that can result in a model being fit as one of several unique local minima. Final model fit accuracy is therefore largely based on the quality of the initial parameter estimate. This makes for widely varying material parameter estimates and causes inconsistent performance comparisons across microfacet models, as will be shown with synthetic data. We proposed a recursive optimization method …

The durability of a hybrid large area additively manufactured fiberglass ABS mold for vacuum infusion of composites was evaluated. The validation was done by designing and fabricating a mold for a custom test artifact and analyzing the surface geometry over the course of multiple infusions until tool failure. After printing and machining, the mold required a sealer to maintain vacuum integrity. The mold was able to produce 10 parts successfully before the sealed tool surface began to tangibly roughen, resulting in increased difficulty of demolding and a rougher surface finish. After the 14th infusion, the part required destructive force to …

The Violent Fecundity Of Mohja Kahl's Translingual Texts, Rachel Norman

Faculty Publications

From publisher: "Scholars writing on US multiethnic literature have described the inclusion of "foreign" languages in fiction as a method for reclaiming power by making the subject impassable, unknowable, or opaque to the monolingual reader. However, these analyses have focused on the incommensurate positions of linguistic insiders and outsiders. This essay contends that Arab American authorMohja Kahfdelivers an alternate ideology in hertranslingualtexts. Writing in a national context that conflates "Arab," "Muslim," and "terrorist" and that uses Arabic as a cultural symbol to denote all three, Kahf employs an aesthetic paradigm to teach her monolingual English-speaking readers Arabic. In doing so, …
