Locating Meaning in the Art-Making Process

Examining the ways that humans derive, cultivate, and encode a sense of meaning and purpose in their lives has always been a concern at the heart of humanities scholarship. In my own journey as an undergraduate and graduate humanities student, this sentiment held true. Through the cross-pollination of my humanities scholarship and my passion for dance led me to the question that guides and structures the project at hand. Specifically I ask: Where is meaning located in the art-making process? To explore this question, I hone in on the processes that guided my own dance-based practice, which exists within the methodological framework of arts-based research. In this essay, I will first give a definition of my craft and of arts-based research, briefly situating the methodology historically and in reference to existing research paradigms. Then I discuss the problem that this project seeks to address, which is namely a lack of focus on public scholarship in the academy. The section to follow delineates my research procedures. In the conclusion I offer my reflections, ultimately averring that meaning in the art-making process is located in acts of spontaneity and deliberation

Framing of fisheries in collapse : a content analysis of two newspapers

"July 2014."Thesis supervisor: Bill Allen.This quantitative content analysis draws from framing theory to examine newspaper coverage of fisheries in collapse. Two groups of newspaper articles formed the population for this census: coverage of the Georges Bank cod fishery by The Boston Globe from 1991 to 1996, and coverage of the Yukon River king (Chinook) salmon fishery in The Anchorage Daily News from 1997 to 2002. With a coding system rooted in Entman's (1993) four-part definition of framing, this study identified occurrences of an economy frame and an ecology frame within the population, as manifested by the explicit terminology used in the texts. Contrary to expectations based on precedents in the literature, the newspapers did not overwhelmingly rely upon economic terms to explain fisheries in collapse. When considered as a whole, the population contains a balance of economic and ecological frames, with the proportion of ecological stories increasing throughout the study period. Individual stories displaying a balance between economic and ecological frames were not common, suggesting that readers would receive a balanced appraisal of the topic only after attention to multiple stories over several years.Includes bibliographical references (pages 74-80)

What Is The Experience of Creating My Own Dance Style?

Through processes of self-inquiry and external inquiry, this heuristic project rigorously investigates the question: What is the experience of creating my own dance style? In exploring the phenomenon of creation, in understanding my own movement with increasing depth and awareness, in articulating my processes and procedures, I hope to create new knowledge both for myself and those with whom it resonates

Sensitivity analysis and determination of free relaxation parameters for the weakly-compressible MRT-LBM schemes

It is well-known that there exist several free relaxation parameters in the MRT-LBM. Although these parameters have been tuned via linear analysis, the sensitivity analysis of these parameters and other related parameters are still not sufficient for detecting the behaviors of the dispersion and dissipation relations of the MRT-LBM. Previous researches have shown that the bulk dissipation in the MRT-LBM induces a significant over-damping of acoustic disturbances. This indicates that MRT-LBM cannot be used to obtain the correct behavior of pressure fluctuations because of the fixed bulk relaxation parameter. In order to cure this problem, an effective algorithm has been proposed for recovering the linearized Navier-Stokes equations from the linearized MRT-LBM. The recovered L-NSE appear as in matrix form with arbitrary order of the truncation errors with respect to ${\delta}t$. Then, in wave-number space, the first/second-order sensitivity analyses of matrix eigenvalues are used to address the sensitivity of the wavenumber magnitudes to the dispersion-dissipation relations. By the first-order sensitivity analysis, the numerical behaviors of the group velocity of the MRT-LBM are first obtained. Afterwards, the distribution sensitivities of the matrix eigenvalues corresponding to the linearized form of the MRT-LBM are investigated in the complex plane. Based on the sensitivity analysis and the recovered L-NSE, we propose some simplified optimization strategies to determine the free relaxation parameters in the MRT-LBM. Meanwhile, the dispersion and dissipation relations of the optimal MRT-LBM are quantitatively compared with the exact dispersion and dissipation relations. At last, some numerical validations on classical acoustic benchmark problems are shown to assess the new optimal MRT-LBM

Multi-domain analysis and prediction of the light emitted by an inductively coupled plasma jet

Inductively coupled plasma wind tunnels are crucial for replicating hypersonic flight conditions in ground testing. Achieving the desired conditions (e.g., stagnation-point heat fluxes and enthalpies during atmospheric reentry) requires a careful selection of operating inputs, such as mass flow, gas composition, nozzle geometry, torch power, chamber pressure, and probing location along the plasma jet. The study presented herein focuses on the influence of the torch power and chamber pressure on the plasma jet dynamics within the 350 kW Plasmatron X ICP facility at the University of Illinois at Urbana-Champaign. A multi-domain analysis of the jet behavior under selected power-pressure conditions is presented in terms of emitted light measurements collected using high-speed imaging. We then use Gaussian Process Regression to develop a data-informed learning framework for predicting Plasmatron X jet profiles at unseen pressure and power test conditions. Understanding the physics behind the dynamics of high-enthalpy flows, particularly plasma jets, is the key to properly design material testing, perform diagnostics, and develop accurate simulation modelsComment: 22 pages (including figures, appendix, and references); 13 figure

Remotely sensing the morphometrics and dynamics of a cold region dune field using historical aerial photography and airborne LIDAR data

The definitive version was published in Remote Sensing 10 (2018): 792, doi:10.3390/rs10050792.This study uses an airborne Light Detection and Ranging (LiDAR) survey, historical aerial photography and historical climate data to describe the character and dynamics of the Nogahabara Sand Dunes, a sub-Arctic dune field in interior Alaska’s discontinuous permafrost zone. The Nogahabara Sand Dunes consist of a 43-km2 area of active transverse and barchanoid dunes within a 3200-km2 area of vegetated dune and sand sheet deposits. The average dune height in the active portion of the dune field is 5.8 m, with a maximum dune height of 28 m. Dune spacing is variable with average crest-to-crest distances for select transects ranging from 66–132 m. Between 1952 and 2015, dunes migrated at an average rate of 0.52 m a−1. Dune movement was greatest between 1952 and 1978 (0.68 m a−1) and least between 1978 and 2015 (0.43 m a−1). Dunes migrated predominantly to the southeast; however, along the dune field margin, net migration was towards the edge of the dune field regardless of heading. Better constraining the processes controlling dune field dynamics at the Nogahabara dunes would provide information that can be used to model possible reactivation of more northerly dune fields and sand sheets in response to climate change, shifting fire regimes and permafrost thaw.Funding for this research was provided by the U.S. Geological Survey Land Change Science and Land Remote Sensing programs, the U.S. Fish andWildlife Service and the University of Alaska Fairbanks
