Maximum Likelihood Estimation of Logistic Sinusoidal Regression Models

Description: We consider the problem of maximum likelihood estimation of logistic sinusoidal regression models and develop some asymptotic theory including the consistency and joint rates of convergence for the maximum likelihood estimators. The key techniques build upon a synthesis of the results of Walker and Song and Li for the widely studied sinusoidal regression model and on making a connection to a result of Radchenko. Monte Carlo simulations are also presented to demonstrate the finite-sample perform… more

An Instructional Approach to Introducing Twentieth-century Piano Music to Piano Students From Beginning to Advanced Levels: a Graded Repertoire for Mastering the Challenges Posed by Logan Skelton’s Civil War Variations

Description: Beginning and intermediate piano students typically study the repertoire of the eighteenth and nineteenth centuries. This pedagogical approach leaves them underprepared to approach compositions written since the latter part of the twentieth-century which are significantly different in terms of harmony, rhythm, meter, and compositional procedure. Therefore, a step-by-step method is necessary to prepare a student for the challenges of learning twentieth and twenty-first century piano music. Civil… more

A Similar Approach with Different Results: the Use of Baroque Elements in Stravinsky’s Suite Italienne (1933), Shostakovich’s Violin Sonata in G Major, Op 134 (1968) and Schnittke’s Suite in the Old Style (1972)

Description: Igor Stravinsky (1882-1971), Dmitri Shostakovich (1906-1975) and Alfred Schnittke (1934-1998) were three of the most important avant-garde Russian composers of the twentieth century. Even though their music shares a number of important traits, their work also reflects very individualized and distinct compositional styles. This study illustrates the similarities in their approach and the contrasting elements present in three selected pieces: Stravinsky´s Suite Italienne for Violin and Piano (193… more

Revisioning a Masterpiece: Jon Magnussen’s “Psalm”

Description: In 2001, composer Jon Magnussen met the unusual challenge of unifying his new score for Psalm, an already-existing dance work from 1967, with the original artistic conceit of the choreographer, José Limón, who died in 1972. Limón was inspired directly by his reading of André Schwartz-Bart’s Holocaust novel, The Last of the Just, and had initially desired to use Stravinsky’s Symphony of Psalms as the score for the dance. Faced with cost-preclusive licensing fees for the Stravinksy, Limón engag… more

Personality Factors and Trust in Placebo Medical Trials

Description: Prior research has reported that individual differences influence both placebo and nocebo responses. The present study examined how individual personality, as well as trust, influence placebo/nocebo belief and symptom reporting after receiving an inert capsule that for some was described as an active “cognitively-enhancing” trial medication. Individuals (N = 104) were randomly assigned to one of three conditions: condition A participants were told they’d received the medication, condition B par… more

Iron Sharpens Iron: Duets for Two Women in the Teaching/instruction of Undergraduate Women

Description: Duet literature remains largely untapped as a pedagogical tool in the undergraduate voice studio. This dissertation examines the ways in which eight duets for female voices, although not written primarily for pedagogical use, may be used to teach four main areas of voice technique: intonation, vocal agility, legato singing, and dramatic skills. Duets are chosen primarily from the standard repertoire and are in English, German, French, Italian and Latin. The compositional styles range from th… more

The Effect of Head Flexion/extension on Acoustic Measures of Singing Voice Quality

Description: A study was undertaken to identify the effect of head flexion/extension on singing voice quality. The amplitude of the fundamental frequency (F0), and the singing power ratio (SPR), an indirect measure of singer’s formant activity, were measured. F0 and SPR scores at four experimental head positions were compared with the subjects’ scores at their habitual positions. Three vowels and three pitch levels were tested. F0 amplitudes and low frequency partials in general were greater with more e… more

Exploring the Impact on Self-regulated Learning: a Comparative Analysis of Learner Experiences Using Problem-based Learning, Game Play, and Computer-based Instruction

Description: The ability to transfer what you know to new and different contexts is a sign of successful learning. While students often graduate from college with the required number of courses many lack the skills necessary to apply appropriate strategies to solve problems in different contexts, to reason, and think critically. More than a decade ago the Boyer Report (1995) pointed to this fact as a sign that Universities were falling short in adequately supporting their undergraduate populations. As a res… more

Development of a Differential Neurocognitive Profile for Alzheimer’s Dementia and Vascular Dementia

Description: Alzheimer’s Dementia (AD) is among the most common diseases in the Geriatric population, and its prevalence is expected to quadruple by 2047.Vascular Dementia (VaD) is the second most frequent cause of dementia, with studies indicating VaD accounts for 10-20% of dementia cases across the globe. A diagnostic model differentiating AD and VaD would be clinically and scientifically valuable, considering the treatment approaches for these conditions are different. Although there are differences betw… more
