Erasing Distinguishability Using Quantum Frequency Up-Conversion

The frequency distinguishability of two single photons was successfully erased using single photon frequency up-conversion. A frequency non-degenerate photon pair generated via spontaneous four-wave mixing in a dispersion shifted fiber was used to emulate two telecom-band single photons that were in the same temporal mode but in different frequency modes. The frequencies of these photons were converted to the same frequency by using the sum frequency generation process in periodically poled lithium niobate waveguides, while maintaining their temporal indistinguishability. As a result, the two converted photons exhibited a non-classical dip in a Hong-Ou-Mandel quantum interference experiment. The present scheme will add flexibility to networking quantum information systems that use photons with various wavelengths.Comment: 4 pages, 5 figure

Splitting HAIR: Reviving the American Tribal Love-Rock Musical in the 1970s

When Hair premiered on Broadway in 1968, the musical garnered attention for its reflection the current cultural moment. Critics acknowledged this congruence of form, content, and zeitgeist as the production’s greatest asset. This alignment with the Vietnam era proved a liability nine years later when Hair received its first Broadway revival, particularly when the musical’s authors replaced many of the libretto’s cultural references with allusions to the 1970s, further illuminating the musical’s inherently time-bound qualities

Selected factors associated with administrators\u27 leadership behaviors and school accountability

In this era of educational accountability, achieving and maintaining high levels of student academic performance is the goal of every school. State accountability models serve as the measure to determine if school districts are successfully educating students, and the responsibility of student academic success rests on the principal of each school. Effective leadership is a necessary component of successful schools, especially in rural school districts. The focus of this research was to explore teachers\u27 perceptions of the leadership behaviors and practices of their principals and determine if relationships existed between the leadership behaviors and the schools\u27 accountability ratings. A survey research design was utilized in this study of eight schools across three rural school districts in central Mississippi. The researcher utilized The Principal Instructional Management Rating Scale to survey 121 teacher participants regarding their perceptions of principals\u27 leadership behaviors or practices. The study revealed no statistically significant relationships existed between principals\u27 leadership behaviors and school accountability ratings. However, the findings support existing literature on the indirect influence of principal leadership on student achievement

The Impact of Childhood Experiences on Intrapersonal and Interpersonal Functioning: Does the Past Dictate the Future?

Childhood experiences of maltreatment are related to interpersonal difficulties in childhood (Pettit, Dodge, & Brown, 1988) and adulthood (Messman-Moore & Coates, 2007; Varia & Abidin, 1999; Busby, Walker, & Holman, 2011). However, most studies have examined the effects of maltreatment on interpersonal functioning (Messman-Moore & Coates, 2007; Busby, Walker, & Holman, 2011) within the context of romantic relationships (Hazan & Shaver, 1987; Feeney & Noller, 1990). Thus, the present study examined the impact childhood maltreatment and neglect has on later intrapersonal functioning and interpersonal interactions and whether gender differences emerge therein. Results indicated maltreated individuals initiate relationships less often and assert lower levels of autonomy within those relationships. Further, men with a history of maltreatment reported lower levels of emotional support, suggesting gender may moderate the relationship between experiences of maltreatment and interpersonal outcomes. Finally, individuals with a history of maltreatment reported lower levels of self-esteem than their non-maltreated counterparts

Kiss today goodbye, and point me toward tomorrow : reviving the time-bound musical, 1968-1975

"July 2014."Dissertation Supervisor: Dr. Cheryl Black.Includes vita.As musical theatre scholars Stacy Wolf, Sheldon Patinkin, and John Bush Jones have argued, American musicals are among our country's most valuable social documents as they depict the dominant discourses and reigning values of the cultural moment from which they first emerged through song, dance, and story. Consequently, all works are innately tied to the era that produced them. Some musicals, however, feature ties to the past are stronger and markedly more visible than others. When the vestiges of the past are so numerous that a given musical says more about the prevailing paradigms of art and thought at a specific moment in American history than it does about the universality of the human condition, then the work might be identified as time-bound. A musical's propensity for time-boundedness is perhaps never more evident than when it is revived years after its original production. When the era that occasioned the piece has passed and the attitudes that it first espoused have changed, a musical that was once fresh and timely can appear quaint, absurd, impolitic, or even myopic to a contemporary audience. Moreover, if the forms of song and dance first employed by that musical are outmoded, and not altered or updated in some way, then the work may read aesthetically as well as socially obsolete. This study offers a systematic investigation of the ways in which theatre artists--directors, designers, composers, librettists, and choreographers--have approached the task of reviving significantly time-bound musicals on Broadway. Through an examination of three representative case studies--Hair (1968), Company (1970), and A Chorus Line (1975)--this project identifies the various ways in which the musicals are anchored to their original era, how those bonds have been negotiated in revivals, and to what effect.Includes bibliographical references (pages 270-280)
