Algebraically Determined Rings of Functions

Description: Let R be any of the following rings: the smooth functions on R^2n with the Poisson bracket, the Hamiltonian vector fields on a symplectic manifold, the Lie algebra of smooth complex vector fields on C, or a variety of rings of functions (real or complex valued) over 2nd countable spaces. Then if H is any other Polish ring and φ:H →R is an algebraic isomorphism, then it is also a topological isomorphism (i.e. a homeomorphism). Moreover, many such isomorphisms between function rings … more

Analyzing Contingencies of Behavioral and Cultural Selection

Description: A choice paradigm was used to evaluate allocation of interlocking behavior of two groups of two participants between responses having operant consequences only and responses having cultural consequences. In a discrete trial BABABAB design, each participant could select one of three options, which delivered either 3 or 5 points. In B (cultural consequence) conditions, two of the options had additional effects: the 3-point option also added 3 points to the other participant's earnings, and one of… more

Antonín Dvořák’s Piano Concerto in G Minor, Opus 33: A Discussion of Musical Intent and Pianistic Effectiveness in Vilém Kurz's Version of the Solo Piano Part

Description: Since its premiere in 1878, Antonín Dvořák’s Piano Concerto in G Minor has been underrated and held in low regard by musicologists, critics, performers and audiences alike. Vilém Kurz (1872-1945), a Czech pianist and pedagogue, revised and reworked the piano solo part to incorporate what he considered to be added brilliance and pianistic effectiveness. However, the revised version has not increased the popularity of the work. In recent decades, this concerto has begun to appear more often in th… more

Anxiety, Depression, and Sleep Disorders: Their Relationship and Reduction with Neurotherapy

Description: This study investigated the relationship among anxiety, depression, and sleep disturbances and the treatment of these three disorders through neurotherapy. Research suggests that these conditions commonly co-occur in the general population and that central nervous system (CNS) arousal may play a primary role in the development and maintenance of these disorders. Several recent studies suggested that neurotherapy, a biofeedback-based treatment for CNS dysregulation, might be an effective treatme… more

Bad Blood: Impurity and Danger in the Early Modern Spanish Mentality

Description: The current work is an intellectual history of how blood permeated early modern Spaniards' conceptions of morality and purity. This paper examines Spanish intellectuals' references to blood in their medical, theological, demonological, and historical works. Through these excerpts, this thesis demonstrates how this language of blood played a role in buttressing the church's conception of good morals. This, in turn, will show that blood was used as a way to persecute Jews and Muslims, and ultimat… more

The Changing Role and Responsibilities of Audit Committees in the United States

Description: The corporate form that developed in the early 20th century created enormous pressure for corporate governance mechanisms to curb the power of corporate managers. Berle and Means, legal pluralists, warned about concentrating economic power in the hands of a small but powerful class of professional managers. They claimed this "new form of absolutism" required governmental oversight and viewed boards of directors as part of management, rather than monitors for shareholders. The Securities and Exc… more

The Cimbasso and Tuba in the Operatic Works of Giuseppe Verdi: A Pedagogical and Aesthetic Comparison

Description: In recent years, the use of the cimbasso has gained popularity in Giuseppe Verdi opera performances throughout the world. In the past, the tuba or the bass trombone was used regularly instead of the cimbasso because less regard was given to what Verdi may have intended. Today, one expects more attention to historical precedent, which is evident in many contemporary Verdi opera performances. However, the tuba continues to be used commonly in performances of Verdi opera productions throughout the… more
