The Phantom Menace: the F-4 in Air Combat in Vietnam

The Phantom Menace: the F-4 in Air Combat in Vietnam

Date: August 2013
Creator: Hankins, Michael W.
Description: The F-4 Phantom II was the United States' primary air superiority fighter aircraft during the Vietnam War. This airplane epitomized American airpower doctrine during the early Cold War, which diminished the role of air-to-air combat and the air superiority mission. As a result, the F-4 struggled against the Soviet MiG fighters used by the North Vietnamese Air Force. By the end of the Rolling Thunder bombing campaign in 1968, the Phantom traded kills with MiGs at a nearly one-to-one ratio, the worst air combat performance in American history. The aircraft also regularly failed to protect American bombing formations from MiG attacks. A bombing halt from 1968 to 1972 provided a chance for American planners to evaluate their performance and make changes. The Navy began training pilots specifically for air combat, creating the Navy Fighter Weapons School known as "Top Gun" for this purpose. The Air Force instead focused on technological innovation and upgrades to their equipment. The resumption of bombing and air combat in the 1972 Linebacker campaigns proved that the Navy's training practices were effective, while the Air Force's technology changes were not, with kill ratios becoming worse. However, the last three months of the campaign introduced an American ...

Phase Separation and Second Phase Precipitation in Beta Titanium Alloys

Phase Separation and Second Phase Precipitation in Beta Titanium Alloys

Date: May 2011
Creator: Devaraj, Arun
Description: The current understanding of the atomic scale phenomenon associated with the influence of beta phase instabilities on the evolution of microstructure in titanium alloys is limited due to their complex nature. Such beta phase instabilities include phase separation and precipitation of nano-scale omega and alpha phases in the beta matrix. The initial part of the present study focuses on omega precipitation within the beta matrix of model binary titanium molybdenum (Ti-Mo) alloys. Direct atomic scale observation of pre-transition omega-like embryos in quenched alloys, using aberration-corrected high resolution scanning transmission electron microscopy and atom probe tomography (APT) was compared and contrasted with the results of first principles computations performed using the Vienna ab initio simulation package (VASP) to present a novel mechanism of these special class of phase transformation. Thereafter the beta phase separation and subsequent alpha phase nucleation in a Ti-Mo-Al ternary alloy was investigated by coupling in-situ high energy synchrotron x-ray diffraction with ex-situ characterization studies performed using aberration corrected transmission electron microscopy and APT to develop a deeper understanding of the mechanism of transformation. Subsequently the formation of the omega phase in the presence of simultaneous development of compositional phase separation within the beta matrix phase of a ...

A Phenomenological Inquiry of Media Literacy of Middle School Students Enrolled in a North Texas Middle School.

A Phenomenological Inquiry of Media Literacy of Middle School Students Enrolled in a North Texas Middle School.

Date: December 2008
Creator: Payne, Sara M.
Description: This dissertation investigated the media literacy experiences of middle school students enrolled in a Texas school. The literature review suggested that middle school students may be overlooked as a distinct population in media literacy research. The primary guiding questions for this inquiry were (1) How is media literacy exhibited by middle school students within a formal school context? (2) How does an elective film and media class impact middle school students' media literacy? And (3) How do middle grade students' responses to media correspond with theoretical models for media literacy? The phenomenological research methodology included a reflective analysis of students' textual responses to non-print media clips (N=24) and a reflective analysis of follow-up personal interviews with a smaller group of middle school participants (n=5). A questionnaire completed by participants provided descriptive statistics about the sample group. Additionally, theoretical models of media literacy were used to evaluate participants' media responses in relation to theoretical constructs for media literacy. The findings resulted in 11 emergent themes which can be used to further discourse about media literacy and its role in middle school curriculum. The dissertation includes implications for educators based upon the emergent themes, as well as recommendations for further research.

Philosophical Ideas in Five Plays by Jean-Paul Sartre

Philosophical Ideas in Five Plays by Jean-Paul Sartre

Date: June 1968
Creator: Portman, Stephen G.
Description: The drama of Jean-Paul Sartre is primarily an investigation into the meaning of the human condition. The question of primary concern is: What does it mean to be a human being? Through his drama, Sartre reveals the nature of the existential situation. This thesis looks at five plays of Sartre and discusses the philosophical ideas in each.

Philosophical Implications on Trombone Performance and Pedagogy in Andre Lafosse's Curriculum at the Paris Conservatory

Philosophical Implications on Trombone Performance and Pedagogy in Andre Lafosse's Curriculum at the Paris Conservatory

Date: May 2005
Creator: English, Bryan
Description: During his tenure as the professor of trombone at the Paris Conservatory, Andre Lafosse wrote the Traite de Pedagogie du Trombone a Coulisse addressing trombone pedagogy that was to be studied in conjunction with his method and etude books, Methode Complete de Trombone and Vade Mecum du Tromboniste. The pedagogic philosophy reflects Lafosse's own experiences as an orchestral musician in France in the early 20th century. Lafosse designed and used his treatise to prepare students to be effective teachers after their graduation from the Conservatory. The scope of preparation for Lafosse's trombone class, however, was limited. He did not attempt to provide a text or tutor that would prepare trombonists for any career in music: Lafosse was primarily concerned with orchestral trombone playing, as reflected in musical exercises, instrument designation, and repertoire references. Solo performance skills are also explained at length in his treatise, and Lafosse includes his own solo transcriptions in the curriculum. This emphasis placed on performing as a soloist appears to oppose Lafosse's implied preference for orchestral performance. Throughout his career as a trombone professor Andre Lafosse compiled and wrote music that emphasized elements of trombone technique based on the French solo and orchestral repertoire. His primary ...
