Discrimination of Time-Compressed Speech Stimuli: a Comparison Study Using a Closed-Set Task With Older Adults

Description: Use of time-compressed speech stimuli has been found to be clinically effective in differential diagnosis of lesions of the temporal lobe. However, notably absent from the literature is information concerning performance of adults on time-compressed closed-set speech discrimination tasks. The goal of this study mas to compare performance of 12 males and 12 females between age 50 and age 70 on a time-compressed closed-set speech discrimination test against the performance of 12 males and 12 females between age 10 and age 28 on the same task. The Word Intelligibility by Picture Identification test (WPI) was presented in both non-compressed and time-compressed conditions to all subjects. Previous research suggests that a difference in performance between age groups and between males and females in the older age group should be expected. Average results indicated negligible differences between age or gender groups under any of the conditions tested. Additionally, the test yielded perfect or near perfect scores for all subjects in the non-compressed condition. Lack of differentiation of results suggests that the Word Intelligibility by Picture Identification CUIPI) may be insensitive to the discrimination disorders expected in older adults, that the subjects included in the study were atypical of older adults in general and therefore such discrimination disorders did not exist in the sample, or that the subjects in the study uiere able to apply some type of compensatory strategies which resulted in the unexpected performance.

The Influence of Chinese Folk and Instrumental Music on Tcherepnin's "Chinese mikrokosmos": A Lecture Recital, Together with Three Recitals of Selected Works of J.S. Bach, W.A. Mozart, C. Debussy, S. Rachmaninoff, D. Shostakovich, and Others

Description: One of the most important compositional theories of Alexander Tcherepnin (1899-1977), Russian-American composer and pianist, is the Eurasian ideology, which was a result of the influence of Eastern culture. Inspired by this theory, Tcherepnin not only extricated himself from his own compositional techniques, but also intensified his search for musical folklore. In April, 1934, he began a world tour which was to include China, Japan, Singapore, the Philippines, Egypt, and Palestine, to search for "musical folklore." He became so fascinated with the culture of ancient China that he cancelled the rest of his arrangements, and, except for visits to Japan, he remained in China for three years, until the outbreak of the Sino-Japanese War in July, 1937. During his three-year stay in China, Tcherepnin was greatly attracted to Chinese culture, and as a result, Chinese culture influenced his music to a significant degree. This essay examines the manner in which Tcherepnin's music was influenced by his experiences in China. In order to precisely analyze the close affiliation between Chinese musical elements and Tcherepnin's "Chinese Mikrokosmos," many original Chinese sources proved indispensable in this study. These sources include Chinese folk music, theater music, instrumental music, religious music, and Chinese periodicals and newspapers that reported Tcherepnin's activities in China (1934-7). The organization of this dissertation as follows: Chapter I provides a brief biographical sketch of Tcherepnin, traces his activities in China, and introduces one of his greatest "Chinese" compositions, "Chinese Mikrokosmos," which represents the fruits of his labors to scrutinize and absorb Chinese musical language. Chapters II and III are devoted to exploring how Chinese folk and instrumental music inspired Tcherepnin's "Chinese Mikrokosmos." Chapter IV summarizes this study.

Regulation of an S6/H4 Kinase in Crude Lymphosarcoma P1798 Preparations

Description: Purified S6/H4 kinase (Mr 60,000) requires autophosphorylation for activation. A rabbit anti-S6/H4 kinase peptide (SVIDPVPAPVGDSHVDGAAK) antibody recognized both the S6/H4 kinase holoenzyme and catalytic domain. Immunoreactivity with p60 kinase protein, and S6/H4 kinase activity were precisely correlated in fractions obtained from ion exchange chromatography of P1798 lymphosarcoma extracts. An enzyme which catalyzed the MgATP-dependent phosphorylation and activation of S6/H4 kinase coeluted with immunoreactivity from Mono 5, but not Mono Q chromatography. Since S6/H4 kinase is homologous with rac-activated PAK65, the observation that phosphorylation is also required for activation suggests a complex mechanism for in vivo activation of the S6/H4 kinase.
