Performance of Adults with and without Attention-Deficit/Hyperactivity Disorder (ADHD) on Measures of Response Inhibition and Frontal Lobe Functioning

Performance of Adults with and without Attention-Deficit/Hyperactivity Disorder (ADHD) on Measures of Response Inhibition and Frontal Lobe Functioning

Date: August 2000
Creator: Wodushek, Thomas R.
Description: In this study 2 groups of adults, those with and without ADHD, were studied in terms of cognitive functioning and symptoms of ADHD, depression, anxiety, and substance abuse. Due to the difficulties in diagnosing ADHD in this population three methods of diagnosis were used and the resulting findings presented. The groups did not differ in measures of depression, anxiety, substance abuse or age. Those adults who met criteria for ADHD showed worse performance on a measure of response inhibition compared to those without ADHD. The patterns of correlations among the cognitive measures differed between the two groups. The conclusions from the findings are discussed in relation to Barkley's (1997) self-regulation model of ADHD.

The performance of density functional theory with the correlation consistent basis sets.

The performance of density functional theory with the correlation consistent basis sets.

Date: August 2005
Creator: Wang, Xuelin
Description: Density functional theory has been used in combination with the correlation consistent and polarization consistent basis sets to investigate the structures and energetics for a series of first-row closed shell and several second-row molecules of potential importance in atmospheric chemistry. The impact of basis set choice upon molecular description has been examined, and irregular convergence of molecular properties with respect to increasing basis set size for several functionals and molecules has been observed. The possible reasons and solutions for this unexpected behavior including the effect of contraction and uncontraction, of the basis set diffuse sp basis functions, basis set superposition error (BSSE) and core-valence sets also have been examined.

The performance of silicon based sensor and its application in silver toxicity studies

The performance of silicon based sensor and its application in silver toxicity studies

Date: August 2000
Creator: Peng, Haiqing
Description: The silicon based sensor is able to detect part per trillion ionic silver in 0.0098% hydrofluoric acid based on the open circuit potential (OCP) measurement. The OCP jump of 100 ppt ionic silver solution is up to 120 mV. The complex agent can effectively suppress the ionic silver concentration and suppress the OCP signal. The ability of complex agent to suppress the OCP signal depends on the formation constant of the complex with silver. The complex adsorbed on the sensor surface induces a second OCP jump, the height of the second jump depends on the formation constant of the complex. The MINEQL chemical equilibrium modeling program is used to calculate the ionic silver concentration when complex agent presents, a discrepancy is found between the MINEQL simulation result and the OCP signal of the silicon based sensor. The toxicity of ionic silver to C. dubia is studied parallel to the OCP signal of silicon based sensor. Less toxicity is found when the complex agent is present similar to the OCP signal. Another discrepancy is found between the MINEQL simulation and the toxicity test when MINEQL simulation is used to predict and control the ionic silver concentration. The data from both biosensor ...

Performance Practice of Interactive Music for Clarinet and Computer with an Examination of Five Works by American Composers

Performance Practice of Interactive Music for Clarinet and Computer with an Examination of Five Works by American Composers

Date: December 2010
Creator: Yoder, Rachel M.
Description: Since the development of interactive music software in the 1980s, a new genre of works for clarinet and computer has emerged. The rapid proliferation of interactive music resulted in a great deal of experimentation, creating a lack of standardization in both the composition and performance of this repertoire. In addition, many performers are reluctant to approach these works due to unfamiliarity with the genre and its technical and musical considerations. Performance practice commonly refers to interpretation of a written score, but the technology involved in interactive music requires a broader definition of performance practice; one that also addresses computer software, coordination between the performer and computer system, and technology such as microphones and pedals. The problems and potential solutions of interactive music performance practice are explored in this paper through review of the relevant published literature, interviews with experts in the field, and examination of musical examples from works for clarinet and computer by Lippe, May, Pinkston, Rowe, and Welch. Performance practice considerations of interactive music fall into the categories of notation, technology, collaboration, interpretation, and rehearsal. From the interviews and the literature, it is clear that the performance of interactive music requires specific knowledge and skills that performers may ...

Performance Rights in Sound Recordings: the Impact of the Performance Rights Act on Radio, Records, and Performing Artists

Performance Rights in Sound Recordings: the Impact of the Performance Rights Act on Radio, Records, and Performing Artists

Date: May 2012
Creator: Wright-Harmon, Joy
Description: The original works of copyright holders included tangible creations, as music written on a page, thereby, extending copyright protection to songwriters and music publishers. Until 1995, absent from U.S. copyright law was protection for copyright owners of intangible sound recordings. the Performance Rights Act (PRA) seeks to amend the US copyright law in order to grant copyright holders of sound recordings the right to performance royalties from terrestrial broadcast radio. If passed, the legislation would be unprecedented in the United States. the PRA has implications for broadcast radio, record labels, and performing artists. This study includes historical and legal perspective of previous attempts at legislation of this nature and predicts outcomes of current legislation.

A Performer's Analysis of Dominick Argento's Miss Havisham's Wedding Night

A Performer's Analysis of Dominick Argento's Miss Havisham's Wedding Night

Date: May 2010
Creator: Mott, Jammieca D.
Description: Dominick Argento's Miss Havisham's Wedding Night is the least explored of his artistic output. A monodrama in one act for soprano, Miss Havisham's Wedding Night contains some of Argento's most beautiful and challenging music of his compositional output. The purpose of a detailed analysis of the structure and content of Argento's Miss Havisham's Wedding Night is to facilitate the solo vocal performer's interpretation. Argento's setting of Miss Havisham's Wedding Night is unique in that he musically translates the manic psychological state of the literary character. Argento structured the one act opera in such a manner that the music would illuminate the text and the audience might connect with the unstable psychological episodes and outbursts demonstrated by Miss Havisham. To that end, each section and phrase has its own psychological motivation, which in turn demands a varied musical and dramatic interpretation. Utilizing selected scenes from Miss Havisham's Wedding Night, the researcher will analyze Argento's musical manifestation of Dickens's literary work. This research will include an investigation into the manner in which Argento uses the shape of melody and the musical phrase along with the harmonic materials to enhance the text and dramatic content. The author will explore the musical nuances Argento ...

Description: Lili Boulanger was an important composer of early twentieth century French music. Her compositional style represents a development and mastery of musical techniques of the great composers of her time including Fauré, Debussy and Wagner combined with her own creative expression. The result is a compelling musical language that was uniquely her own. She held an important place among her contemporaries in Paris and her accomplishments were considered newsworthy during her lifetime (1893- 1918). She obtained a much sought-after publishing contract with Ricordi. Her more famous sister, Nadia Boulanger, felt that Lili was the better composer of the two, and her peers and music professors clearly felt that both her musical and personal qualities were extraordinary. Evidence of her intelligence, creativity, and artistic growth can be seen in her music. As the first woman to win the Prix de Rome (July 5, 1913), Lili Boulanger, unlike Clara Schumann, Fanny Mendelssohn, or Alma Mahler, was acknowledged and acclaimed during her lifetime for her skill as a composer. Yet, nearly a century later the music of this talented French composer is not as well known as it deserves to be. In an effort to discover the reasons for this relative anonymity, this ...

A Performer's Analysis of Maurice Ravel's  Chansons madécasses: A Lecture Recital, Together with Three Recitals of Selected Works of B. Britten, R. Schumann, S. Barber, T. Pasatieri, F. Poulenc, G. Verdi, T. Arne, and Others

A Performer's Analysis of Maurice Ravel's Chansons madécasses: A Lecture Recital, Together with Three Recitals of Selected Works of B. Britten, R. Schumann, S. Barber, T. Pasatieri, F. Poulenc, G. Verdi, T. Arne, and Others

Date: May 2004
Creator: Ellis, Diana Lea
Description: In his song cycle, Chansons madécasses (1926), a chamber work for voice, piano, flute, and cello, Maurice Ravel combines twentieth-century musical experimentation and exoticism with the late nineteenth-century style characteristics present in the vocal elements and instrumentation. Because early twentieth-century music appears to be closely connected to modern concerns, performers may tend to dismiss the style and technique of the early twentieth century as simply "old-fashioned" rather than examine and consider those elements as resources and valuable tools for interpreting and presenting authentic performances. The focus of this research includes a discussion of the historical, social, and textual implications of the music and poetry; a formal musical analysis of the work, including comparisons of an early twentieth-century, mid-century, and late twentieth-century recordings with regard to the use of vibrato and portamento in the voice, cello, and flute; and an examination of Chansons madécasses for elements of authentic Malagasy music and poetry. The paper also suggests methodologies for performance practice which reflect the results of these analyses. The beginnings of the rejection of traditional form - harmonic, rhythmic, and melodic structures - found in the early part of the century began to free composers and performers to explore musical presentations that ...
