Science has featured intermittently as the subject of theatrical texts since Thomas Shadwell first represented the Renaissance scientist in The Virtuoso (1676). The late twentieth century, however, saw an incremental growth in theatre's interest in scientific exploration, a growth concommitant with the vast impact that science has had on technology, warfare and the machinations of political power. The tensions generated by the disjuncture between the rationality of science and the unpredictability of human society have provided a rich source of material for theatrical investigation into the human experience. The purpose of this thesis is twofold: to reveal some of the thematic concerns that emerge in this genre, and to examine the interplay between theatre and science. Shelagh Stephenson's An Experiment with an Air Pump (1999) provides a useful point of focus for this inquiry. By parallelling two time periods, exposing the scientific objectification of women and, in addition, opening up contemporary ethics for negotiation with the audience, Stephenson calls into question the objectivity and certainty of history, gender and ethical conduct. These she presents as dynamic and evolving fields of discourse that contribute to, but do not solely constitute, knowledge and understanding of the world. An Experiment with an Air Pump also displays an awareness, through its metatheatricality, of theatre itself as an imaginative, subjective discourse which parallels the more intuitive and personal aspects of scientific exploration. The play functions as a microscope, bringing into focus a contemporary world in which traditional systems of understanding and knowledge need to be reassessed and reinvented.

No / The Raman spectra of two historical specimens of human hair attributed to the engineer Robert Stephenson and scientist Sir Isaac Newton, preserved in private collections are reported. Comparisons are made with the Raman spectra of modern hair specimens and with hair from archaeological excavations. The hair spectra collected with a laser excitation of 785 nm are of a better quality than those collected using 1064 nm. The historical hair specimens are remarkably well-defined spectroscopically in terms of the amide I vibrational mode and the ν(SS), ascribed to a predominantly gauche–gauche–gauche CSSC conformation. The contrast with degraded hair specimens recovered from archaeological excavations is striking. The presence of a weak feature near 2590 cm−1 in the hair samples attributed to a ν(SH) vibration could be indicative of a reduction process operative on the CSSC cystine keratotic linkages and a possible origin of this is bacterial biodegradation identified histologically. This study demonstrates the molecular information available from non-destructive Raman spectroscopic analysis from single hair shafts or small bundles of fibres which complements information available from histological and destructive analytical techniques for rare biological specimens subjected to conservation or curation procedures in museums or private collections.

nforme final de Seminario para optar al grado de Licenciada en Lengua y Literatura Hispánica con mención en Literatura / En este primer capítulo nos proponemos mostrar un panorama general acerca de la ciencia ficción (en adelante CF) y las problemáticas que pueden desprenderse de ella, para así tener una base sobre la cual instalar nuestros análisis personales de diferentes novelas del género. La primera parte del Seminario de Grado el curso se enfocó en abordar lo que más adelante expondremos, es decir, la historia del género, su definición, y sus distintas manifestaciones en subgéneros; para lo cual leímos y vimos varias o bras que resultan representativas de la CF. Además, se dedicó tiempo a procesar la bibliografía con la que trabajaremos, y a discutir distintos aspectos de la misma. Así, durante la segunda parte del curso, enfocada a la producción de nuestros informes fin ales, pudimos aplicar y ampliar lo visto en clases en función de la obra que cada uno decidió analizar. Antes de comenzar, es pertinente mencionar un suceso que tomó lugar tras asistir al primer encuentro de seminario de grado: nos enteramos de que todos manejamos un nivel de inglés que nos permite leer en el idioma. Este aspecto resultó relevante, pues la gran mayoría de las obras y bibliografía de ciencia ficción es producida por angloparlantes. Luego de llegar un acuerdo común, el profesor guía decidió reestructurar el programa del curso, en función de incluir textos actuales que carecen de traducciones. Tal decisión impactó nuestro paso por el seminario, pues el espectro de posibilidades para elegir nuestro objeto de estudio se vio favorablemente ampliado.

Der Begriff der Maßsynthese bezieht sich auf die Anwendung bestimmter geometrischer Verfahren zur Maßbestimmung ebener Koppelgetriebe und ist im klassischen Maschinenbau ein Baustein bei der Entwicklung von Antriebssystemen zur Erzeugung nichtlinearer Bewegungen. Eben jener Entwicklungsprozess ist jedoch durch ein streng hierarchisches Vorgehen geprägt. So erfolgt nach der Maßbestimmung die Dimensionierung des Mechanismus und anschließend dessen kinetische Betrachtung. Bisherige Arbeiten auf dem Gebiet der Mechanismendynamik, -synthese und -optimierung behandeln die einzelnen Schritte losgelöst voneinander. Gelenkabstände und Gliedwinkel ebener Koppelgetriebe werden, beispielsweise bei einem dynamischen Ausgleich, als unveränderlich betrachtet. Auf der anderen Seite gibt es keine praktischen Ansätze zur kinetischen Beurteilung der Lösungen während der Maßsynthese, was vor allem auf die zum Zeitpunkt der Synthese unbekannten Masseparameter zurückzuführen ist. Ziel der Untersuchungen und Gegenstand des Vortrages ist ein neuer Ansatz, welcher auf Basis eines modularen Synthesekonzeptes innerhalb eines Systemsimulators die Betrachtung kinetischer Kenngrößen, wie Gelenkkräfte, Energiebilanz, Gelenkspiel oder FFT während der Synthese ermöglicht. Dieser kontinuierliche Analyse-Synthese-Parameter-Abgleich (ASPA) ermöglicht die Optimierung des Mechanismus während der Synthese unter Berücksichtigung kinetischer Kenngrößen. Neben der Vorstellung des modularen Synthesekonzeptes werden Möglichkeiten zur Beschreibung der Masseparameter während der Synthese und Wege zur Optimierung der freien Parameter dargestellt.

Using Joseph Wright's painting, An Experiment on a Bird in the Air Pump as an inspirational starting point, Shelagh Stephenson's An Experiment with an Air Pump explores the depth of human existence using universal conflicts such as: morals versus ethics, science versus God and right versus wrong. Since the play's premiere in 1998, it has provided a forum for hot button topics such as stem cell research, abortion, and scientific experimentation. The University of New Orleans' production not only presented the issues in the play, it strives to be an example of theatrical excellence, challenge and engage both the company and the audience.

Thesis (MA)--Stellenbosch University, 2000. / ENGLISH ABSTRACT: Cyberpunk literature explores the effects that developments in technology will have on the lives of individuals in the future. Technology is seen as having the potential to be of benefit to society, but it is also seen as a dangerous tool that can be used to severely limit humanity's freedom. Most of the characters in the texts I examine wish to perpetuate the boundaries that contain them in a desperate search for stability. Only a few individuals manage to move beyond the boundaries created by multinational corporations that use technology, drugs or religion for their own benefit. This thesis will provide a definition of cyberpunk and explore its development from science fiction and postmodern writing. The influence of postmodern thinking on cyberpunk literature can be seen in its move from stability to fluidity, and in its insistence on the impossibility of creating fixed boundaries. Cyberpunk does not see the future of humanity as stable, and argues that it will be necessary for humanity to move beyond the boundaries that contain it. The novels I discuss present different views concerning the nature of humanity's merging with technology. One view is that humanity is moving towards a posthuman future, while some argue that humanity is not discarded, but that these characters have merely evolved to the next step in the natural development of humankind. Both these views deal with constant change, a notion advocated by both postmodernism and cyberpunk. / AFRIKAANSE OPSOMMING: "Cyberpunk" literatuur ondersoek die uitwerking wat tegnologiese ontwikkeling in die toekoms op die lewens van individue sal hê. Tegnologie word gesien as tot moontlike voordeel vir die samelewing, maar dit kan ook 'n gevaarlike wapen wees wat gebruik kan word om die mens se vryheid in te perk. Die meerderheid van die karakters in die romans wat ek bespreek verkies om die grense wat hulle inperk te handhaaf in 'n desperate strewe na stabiliteit. Slegs 'n paar individue kry dit wel reg om verby die grense te breek wat deur multinasionale organisasies geskep word vir hul eie gewin. In hierdie tesis kyk ek na 'n definisie van "cyberpunk" en ek ondersoek die invloed van wetenskapsfiksie en postmodernisme op die ontwikkeling van die beweging. Die invloed van postmodernistiese denke kan gesien word in "cyberpunk" se fokus op veranderlikheid eerder as stabiliteit. "Cyberpunk" sien nie die toekoms van die mens as stabiel nie, en die argument is dat dit nodig is vir die mens om verby die grense te beweeg wat vryheid inperk. Die romans wat ek bespreek bevat verskillende sieninge oor die tipe samesmelting wat die mens en tegnologie sal hê. Sommige voel dat die kategorie "mens" permanent agterlaat gaan word, terwyl ander argumenteer dat individue slegs sal ontwikkel tot die volgende stap in die natuurlike ontwikkeling van die mens. Voortdurende verandering is die fokus van beide hierdie standpunte, en dit is ook die belangrikste fokus van beide "cyberpunk" en postmodernisme.

Since the 18th century, composers have utilized the symphony to communicate thoughts and ideas through the vehicle of a large ensemble composed of a variety of instrumental colors. Though the structure of the symphony has understandably been subject to the varied interpretations of composers over the past 300 years, several characteristics of the traditional symphony do seem to have stood the test of time. In this document, the recent developments of the American symphony for wind band is discussed, focusing on the ways in which recent works both adhere to and divert from the traditional understanding of the classical symphonic form and highlighting the resurgence of the form by wind band composers. For the purposes of this study, David Dzubay's Symphony No. 2: Through a Glass Darkly, James Stephenson's Symphony No. 2: Voices, Donald Grantham's Symphony No. 2: After Hafiz, and Kevin Walczyk's Symphony No. 4: Unforsaken are used to demonstrate how each composer writes in their own unique style using contemporary techniques, while still appearing to maintain traditional aspects of the symphonic form, whether consciously or subconsciously. For each of the four works, a structural analysis is conducted using a rubric of standard symphonic norms. Additionally, interviews were conducted with each composer, providing insight on their compositional process, the commissioning process, and their thoughts on the symphonic form for wind band. The responses each composer gave during their interviews is incorporated into the analysis of each work, allowing the composer's own voice to supplement the findings.

Thesis (MMus (Music))--University of Stellenbosch, 2009. / This study represents a contribution to the subject-didactical review of three prominent compositions for the violin by three prominent South African composers, namely the Sonata on African Motives by Stefans Grové (1985), Luamerava by Hendrik Hofmeyr (2000) and the Concerto for violin and orchestra by Allan Stephenson (2007). The three composers are discussed with reference to biographical detail and broad compositional style, while the works are reviewed according to musicological aspects as well as violin specific didactical aspects. To avoid too much repetition, a chapter concerning technical issues and practice methods pertaining to all three works was added. In the Sonata on African Motives, Stefans Grové merges his “old” compositional style, in this work loosely represented by a lack of tonality and metre, as well as complicated use of rhythm, with his “new” African voice (1984-). The African voice, represented by a melody he overheard a black roadworker sing, ties the work together. The sonata consists of five movements, with the first and fourth movements, and the third and fifth movements linked through content. This work presents challenging ensemble playing, rhythmic detail, diverse timbre changes in the violin part, as well as pitch difficulty due to unusual intervals without tonal context. Hendrik Hofmeyr‟s Luamerava was commissioned by SAMRO for the overseas scholarship. The title refers to the last of the mythical Children of the Lost Star who lived in the Cariba gorge on the banks of the Zambezi river (according to Mutwa‟s description of the oral culture of the people of that region). The piece, like the Grové, is thus linked to Africa. The work was composed for solo violin, Hofmeyr makes the most of the lyrical and sonorous qualities of the instrument. Compared to the other two works studied, Luamerava presents the most advanced technical challenges, with extensive doublestopping being the main challenge. Allan Stephenson‟s Concerto differs significantly from the other two works studied in the sense that it is instantly appealing to the general music lover, mainly because of his use of easy flowing melodies. The concerto has, as is tradition, three movements. Although the work contains ample technical challenges, it is obvious that it was composed by a string player – both the extensive running passages and double stopping are quite possible to play once good fingerings have been found. In the discussion of these works, attempts at solving specific technical problems are made.
