Authors: Baszkin Adam , Rosilio Veronique , Puisieux Francis , Albrecht Genevieve , Sunamoto Junzo 
Published: May 2006

Abstract
Surface potential measurements were performed for the systems of egg phosphatidylcholine (PC)/cholesteryl-amylopectin and egg PC/cholesteryl-pullulan. The variations of surface potential of phospholipid monolayers on injection of polysaccharide derivatives into the aqueous subphase were monitored for various surface densities of phospholipids and polysaccharide solution concentrations. At the phospholipid surface concentrations above 1014 molecules/cm2, the changes in the surface potential of monolayers were shown to be higher for amylopectin than for pullulan.

Published: May 2006

Abstract
The doubly doped In2O3 thick film element, Pd–La2O3–In2O3, was found to show excellent ethanol gas sensing properties in sensitivity, selectivity and response rate, in addition to having an electric resistance low enough to be compatible with a conventional circuitry. Such properties resulted from the modifications of In2O3-based element with the dopants and the thick film structure applied.

Authors: Takita Yusaku , Yamada Hiroshi , Hashida Masayo , Ishihara Tatsumi 
Published: May 2006

Abstract
CCl2FCClF2 was converted to C2H2F2 and CH4 over Pd/TiO2 at 420–820 K in the presence of hydrogen. C2H2F2 and C2H3F3 were mainly formed over Pt/TiO2 at 520–570 K and dechlorination to CF3Cl took place over Ni/TiO2 and Co/TiO2 at 470–620 K. The CeO2/TiO2 catalyst and the catalyst containing La themselves reacted with CFC113 to give CeF3/TiO2 and LaF3/TiO2 after the reaction at 820 K, respectively. MnTiO3 catalyzed the reaction to C2F3Cl at relatively high temperatures of 770–820 K.

Surgical Repair of Unidirectional Palatopharyngeal Epignathus: Case Report and Review of Literature
Authors: El-Musa Kusai A. , Shehadi Ramzi S. , Shehadi Sameer 
Published: May 2006

Epignathus is an extremely rare, benign, congenital teratoma that arises from within the oral cavity and may be attached to the mandible, palate, or base of the skull. Because of its location, it can cause airway and feeding problems, as well as secondary defects due to the presence of an intraoral tumor. This tumor usually causes death in neonates, due to airway obstruction. Surgical removal is usually impossible, especially in large tumors (Stone, 1951; Bennett, 1970). A patient with a neonatally diagnosed nonobstructive palatopharyngeal epignathus is described. It was associated with a shortened palate, cleft uvula, and velopharyngeal insufficiency, and was successfully excised surgically.
Working and Dancing: A Response to Monroe Beardsley's “What Is Going On in a Dance?”
Authors: Carroll Noël , Banes Sally 
Published: May 2006

Professor Beardsley's paper is distinguished by his customary clarity. Many of the distinctions he draws will undoubtedly be useful not only for dance theoreticians, but for dance critics as well. Nevertheless, the way that these distinctions are placed in the service of a putative characterization of what constitutes a dance “moving” seems to us problematic. This brief note will be devoted to exploring the adequacy of Professor Beardsley's proposal.Beardsley appears to conclude his paper by stating a condition requisite for a motion to be counted as a dance “moving.” He writes,If, in other words, there is more zest, vigor, fluency, expansiveness, or stateliness than appears necessary for its practical purposes, there is an overflow or superfluity of expressiveness to mark it as belonging to its own domain of dance.We interpret Beardsley's basic point here as the claim that a superfluity of expressiveness (above the requirements of practical exigencies) is a defining feature of a dance “moving.” However, in our opinion, this attribute represents neither a necessary nor a sufficient condition of dance.
Valentine de Saint-Point
Authors: Satin Leslie 
Published: May 2006

On April 3,1917, dancer Valentine de Saint-Point performed at New York City's Metropolitan Opera House. It is accepted as common knowledge (a term which may be stretching the point somewhat, given the relatively small body of writings which refer to her) that she was a) a Futurist, b) one of the very few, if not the only, female Futurists, and c) the only, if not one of the very few, Futurists to perform in New York.Actually, none of these “facts” is entirely documented. In this essay, I will leave the third point untouched, assuming this aspect of Saint-Point's singularity to be at least relatively accurate. The second point I will deal with obliquely; that is, rather than debating whether her position as a woman among the Futurists was unique, I will consider how she saw being female as meaningful in her work. The first point interests me as well—again, obliquely. I will not argue here for or against Saint-Point's definitive categorization as a Futurist. Instead, by verbally reconstructing a performance and analyzing a body of written work related to it, I will examine Saint-Point's associations with Futurism and other experimental movements in performance taking place within the same general timeframe.
Recruitment Patterns: their impact on ballet and modern dance
Authors: Sussmann Leila 
Published: May 2006

English sociologist of art Janet Wolff says that all art is situated both historically and in relation to the status groups that produce it and share a taste for it. Tracing the relationships between the situation and the art is the difficult task of the sociology of art.The theoretical model used by art historians results in their focusing heavily on the body of art itself, showing how styles influence and develop out of each other. Alternatively, the “interpretive” theory of anthropologist Clifford Geertz—described in his essay, “Art as a Cultural System” —emphasizes the idea that the meaning system of the art participates in the larger meaning system of the culture: the larger system provides the key to the art.
In Search of Satanella: An Adventure Prompted by The Children of Theatre Street
Authors: Cohen Selma Jeanne 
Published: May 2006

Ever since I was fourteen and read Tamara Karsavina's Theatre Street, I had wanted to visit the school that she described so endearingly in her autobiography. Finally, in 1973,1 was in Leningrad and had a chance to see what is now known as the Vaganova Choreographic Institute. After several engrossing hours of watching classes, I was called into the office where I was invited to ask questions but was first asked to listen to an explanation. “We know,” said the young man appointed as spokesman, “that you have visited the very modern new school that is now used by the Bolshoi Ballet. We want you to know that we, too, were offered a new building by the Soviet government, but we did not accept it. We told the government that, unlike Moscow, we have a great tradition that was created and nurtured within these walls. We are proud of this tradition and we want to remain here.”If I had not already loved the Leningrad school because of Karsavina, I would have loved it then.The film The Children of Theatre Street tries to capture some of this feeling of inheritance, and at times it succeeds. We see the rapt faces of the young students as they stand beneath portrait's of past masters who walked these same halls, beneath views of dancers who preceded them, perhaps at that same space at the barre. The face of tradition, like that of a parent, is both loving and demanding. The children are intensely aware of their responsibility; we respond to their consuming dedication as the film concentrates on the daily lives of two young students, Angelina Armeiskaya and Alec Timoushin. But watching moments of their classes, we long to see more of their dancing. Of course, it is interesting to see the school cafeteria and a dormitory bedroom, but a glimpse would have sufficed.
Studying Water Study
Authors: Marion Sheila 
Published: May 2006

Water Study, choreographed by Doris Humphrey in 1928, is described by dance writer Marcia B. Siegel as “still one of the most extraordinary works in American dance.” One of Humphrey's earliest works, it was created during the period in which American modern dancers Humphrey, Charles Weidman, and Martha Graham broke away from the ersatz ethnicity of Denishawn to begin choreographing their own works. “As small and strange as it is,” Siegel continues, “Water Study is a masterpiece of the choreographic art”.The piece begins with ten to twelve dancers crouched low on the floor, scattered throughout the stage area, and all facing stage right. They slowly rise and sink in canon, as though a wave passed over them and back again. The movement grows until it brings them onto their feet: they separate and rush toward one another, leaping and falling like waves splashing together and subsiding. Then, grouped together, they surge back and forth from one side of the stage to the other like shifting tides. One cluster of dancers breaks away while another leaps, turns, and falls, forming a progressive, whirl-pool-like spiral to the floor. A side-to-side rocking motion gradually brings the dancers into unison as they spread throughout the stage area again. They return to the crouching position and ripple upward again in one last splash before finishing with a slow crawling action that leaves them prone like the last remnant of a wave creeping up the shore.Water Study focuses attention on movement by minimizing other theatrical elements. The dance does not tell a story; it is performed in silence with no scenery; lighting changes are minimal; and dancers are costumed in plain, flesh-colored leotards. Although these kinds of choices tell their own story, as will be examined later, they serve to “turn the volume up” on the movement “channel” of communication.
East and West in the Work of Michio Ito
Authors: Cowell Mary-Jean , Shimazaki Satoru 
Published: May 2006

The integration of Oriental and Occidental elements, as Michio Ito perceived them, was central to his vision of art and life. “In my dancing,” he said, “it is my desire to bring together the East and the West. My dancing is not Japanese. It is not anything—only myself”.Ito thus described his dancing in a newspaper interview in August, 1917, less than a year after his arrival in America. Those who view the individual as inevitably embedded in his specific cultural and historical environment may find Ito's description idealistic but naive. He was, after all, only twenty-three. Certainly, Ito was inescapably an Oriental from the standpoint of the Western formulated Orientalism described by Edward Said. Moreover, Ito's prior experience in Europe had already acquainted him with the Orientalist tendency to lump together all Eastern cultures, assuming, for example, that values and behavior of Japanese, Indians, and Egyptians must be similar if not identical. As the only Asian among well over three hundred students at the Dalcroze Institute, Ito noted that, despite his protests, other students regarded what he said and did as typical of all Eastern people as well as all Japanese. Ito, then, was not naively oblivious to contemporary stereotypes of Orientals.Ito's concept and practice of his art reflects some aspects of Said's Orientalism while evading others. This is partially because Said's study admittedly emphasizes British and French scholarship and imperialist politics, particularly in relation to the Arab world. In this Orientalist tradition, the European saw the Oriental as essentially different and inferior, the passive “other” incapable of self-government despite past glories of Eastern philosophy and art. Consequently, Orientalism logically predicted and justified the colonization of the colonized. Moreover, since the East was thought to have unchanging characteristics, this dominant-subservient relationship was assumed static until the dissolution of the imperialist empires in the twentieth century.
