An examination of the keyboard technique of Bach, Haydn, Chopin, Scriabin and Prokofiev

Master's Project (M.Mu.) University of Alaska Fairbanks, 2016In this research paper, I will explore the keyboard technique of each composer presented in my recital: J.S. Bach, Franz Joseph Haydn, Frederic Chopin, Alexander Scriabin and Sergei Prokofiev. I hope to elucidate the physical approach used by each composer, and show in turn how that same approach influenced the music of each composer by analyzing the pieces performed in my recital. To understand the distinct technique of the composers, it is important to know some context. The instrument each composer wrote for necessarily influenced their technique and resulting composition. However, the instrument cannot explain every facet of technique, and it becomes necessary to understand the underlying aesthetics of technique. Moving chronologically from Bach to Prokofiev, a general trend of expansion in the use of the hand and arm will be seen throughout. Keyboards became louder and heavier in touch and the hand faced greater reaches in every generation. The technique of Bach and Haydn was largely focused on compact and relaxed hands with distinct finger movements, while Scriabin and Prokofiev at the other end require sweeping gestures that occupy the entire arm. However, it would be too easy to present this progression as a story that technique is only getting better and better, implying that the older composers were inferior to the later. That is simply false. Instead, extended study of each composer shows that many technical principles are universal. The baroque keyboardists were likely playing with more weight than popularly imagined and one cannot play Scriabin with mittens on the hands

CONTRACTING OVER COMMON PROPERTY: COST-SHARE CONTRACTS FOR PREDATOR CONTROL

Predator control cost-share contracts among livestock producers in North America date back to 1630. A model is developed which provides refutable implications for the structure and distribution of these contracts over time and space. Historical and contemporary state and county level data on sheep producer coyote control generally support the model.contract theory, wildlife, livestock production, Industrial Organization, Resource /Energy Economics and Policy,

The Impact of Olfactory Cues on Attention: The Case of Stroop Interference

This study explores the relationship between odor imagery, color associations, and visual attention through a Stroop-task based on common odor-color associations. This Stroop-task was designed using three fruits with odor-color associations: lime with green, strawberry with red, and lemon with yellow. Each possible word-color combination was lexically presented in the experimental trials. Three experiments were conducted that used the Stroop-task with different odors present. They suggest that odor imagery can affect visual attention, the inhibition of odor-color associations, and that odor imagery appears to be facilitated in the presence of a related odor

The Impact f Olfactory Cues on Attention: The Case of Reverse Stroop Interference

Ham and Koch (2019) found that an odorant could influence interference on a modified Stroop task. This study was conducted to examine the impact of olfactory cues on reverse Stroop interference. Across three experiments, participants completed a modified reverseStroop task in which they identified a word (strawberry, lime, lemon) in different color fonts (red, green, yellow). Although the words were fruit names instead of color names, each word had some degree of association with a particular color (e.g., lime and green). In Experiment 1, congruent and incongruent trials were presented without an odorant. No differences were found between congruent and incongruent trials (t(28) = .63, p \u3e .05; d = .12). Experiment 2 consisted of the same task; however, an orange odorant was added to the room. RTs were faster for congruent trials than incongruent trials (t(17) = 4.15, p \u3c .001; d = .98). Lavender odorant was used in Experiment 3 to test whether the RT differences in Experiment 2 were influenced by the presence of a related odorant or any odorant. No differences were found between conditions (t(27) = 1.89, p \u3e .05; d = .36). The results indicate that a task-related odorant can impact word identification in a modified Stroop task

New easy-plane CPN−1\mathbb{CP}^{N-1} fixed points

We study fixed points of the easy-plane $\mathbb{CP}^{N-1}$ field theory by combining quantum Monte Carlo simulations of lattice models of easy-plane SU($N$) superfluids with field theoretic renormalization group calculations, by using ideas of deconfined criticality. From our simulations, we present evidence that at small $N$ our lattice model has a first order phase transition which progressively weakens as $N$ increases, eventually becoming continuous for large values of $N$. Renormalization group calculations in $4-\epsilon$ dimensions provide an explanation of these results as arising due to the existence of an $N_{ep}$ that separates the fate of the flows with easy-plane anisotropy. When $N<N_{ep}$ the renormalization group flows to a discontinuity fixed point and hence a first order transition arises. On the other hand, for $N > N_{ep}$ the flows are to a new easy-plane $\mathbb{CP}^{N-1}$ fixed point that describes the quantum criticality in the lattice model at large $N$. Our lattice model at its critical point thus gives efficient numerical access to a new strongly coupled gauge-matter field theory.Comment: 12 pages, 9 figure

PRESCRIBED FIRE: LIABILITY, REGULATION, AND ENDOGENOUS RISK

This paper compares the incentive effects of strict liability and negligence rules when timing of activity affects environmental risk. The model is developed in the context of prescribed fire as a land management input, with an extension to the related problem of wildfire risk mitigation through vegetation management. The use of prescribed fire for land management and wildfire risk control is increasing in parts of the United States, and related liability and regulatory law is changing with it.Resource /Energy Economics and Policy,
