Portfolio of recorded performances and exegesis: Messiaen’s musical language for the jazz pianist - an exploration through performance.
Get PDFMoving beyond Gunther Schuller’s Third Stream amalgamation of classical and jazz, this study explores whether the musical language of Olivier Messiaen can make a valid contribution to jazz piano performance. Initially, my project sought to answer such questions as: What elements of the musical language of Messiaen already exist in the jazz vocabulary? Am I able to extend this further? What are the timbral structures and pianistic effects within Messiaen’s musical language? What will be the most effective application of Messiaen’s musical language to jazz piano performance? Endeavouring to answer the final question led me to consider such aspects as whether the project should be limited to quoting Messiaen motifs, arranging Messiaen melodies, replacing jazz harmonic structures on standards with examples from Messiaen’s musical language or whether it would be better to approach the research conceptually. The work of Hubert Nuss provided encouraging reassurance that this was not an impossible task. In order to articulate this conception, the initial challenge was to decide how the classical and jazz worlds might meet in a ‘Messiaen’ technique. The approach adopted was similar to that used for undergraduate jazz study, namely, immersion in the piano scores and recordings of Messiaen’s music as well as by live performances. This was followed by the development and assessment of a contrived approach when specific techniques, such as tonal colourings or harmonic structures, were developed through prepared exercises and consciously included in my performance. It was then compared with an intuitive approach when no such precise parameters were established. This submission consists of CD recordings of two public recitals and an exegesis. It documents the development of this Messiaen technique and discusses its application in my performances. It also demonstrates the ways that Messiaen’s musical language can be used within jazz piano performance to provide a colour that distinguishes jazz piano performance in a competitive field.Thesis (M.Mus.) -- University of Adelaide, Elder Conservatorium of Music, 201
Instabilities of active polar fluids in the Taylor-Couette geometry and migration analysis of human immune cells
No full textEine wesentliche Eigenschaft lebendiger Materie ist ihre „Aktivität“, also die Fähigkeit, chemische in mechanische Energie umzuwandeln. Das Konzept des „aktiven polaren Fluids“ ermöglicht eine Kontinuumsbeschreibung einer Vielzahl von biologischen Systemen unter besonderer Berücksichtigung gebrochener räumlicher Symmetrien. Wir untersuchen die Dynamik eines solchen Fluids in einer planaren Taylor-Couette-Geometrie, einer ebenen Fläche, die durch konzentrische Zylinder begrenzt wird. Wir finden in Abhängigkeit von der Aktivität des Systems eine Vielzahl spontaner Strömungsmuster, insbesondere auch in Abwesenheit externer Drehmomente.
Als Beispiel für ein aktives System analysieren wir die Migration von CD8⁺ T-Zellen und Natürlichen Killerzellen (NK-Zellen), zweier wesentlicher Bestandteile des menschlichen Immunsystems. Die zugrunde liegenden in-vitro Experimente wurden von Mitarbeitern der Arbeitsgruppe Markus Hoth (Lehrstuhl für Biophysik, Universität des Saarlandes) durchgeführt. Von besonderem Interesse sind dabei die Geschwindigkeit sowie die Persistenz der Bewegungsrichtung der Zellen. Wir modellieren die Bewegung der Zellen als persistenten Random Walk mit Ruhezeiten und vergleichen dies mit alternativen Modellen.An essential property of living matter is its “Activity”, i.e. its ability to transform chemical into mechanical energy. The concept of “active polar fluids” enables us to mathematically describe a large class of such biological systems while considering broken spatial symmetries. We analyze the dynamics of an active polar fluid in a planar Taylor-Couette geometry. i.e. a planar space bounded by two concentric cylinders. Depending on the system's activity we find several classes of spontaneous flow patterns, even in the absence of external torques.
As an example of an active system, we analyze the migration of CD8⁺ T-cells as well as natural killer cells (NK cells), which are essential components of the human immune response. The in-vitro experiments have been performed by members of the group of Markus Hoth (Biophysics, Saarland University). We are especially interested in the velocities as well as the persistence of direction of the cells' motion. We model the motion as persistent random walks with resting phases and compare this model to alternative ones

Big Data, Big Libraries, Big Problems?: the 2014 LibTech Anti-talk?
Get PDFThe desire to create automatons is a familiar theme in human history, and during the age of the Enlightenment mechanical automatons became not only an “emblem of the cosmos”, but a symbol of man’s confidence that he would unlock nature’s greatest mysteries and fully harness her power. And yet only a century later, automatons had begun to represent human repression and servitude, a theme later picked up by writers of science fiction. Man’s confidence undeterred, the endgame of the modern scientific and technological mindset, or MSTM, seems to be increasingly coming into view with the rise of “information technology” in general and “Big data” in particular. Along with those who wield them, these can be seen as functioning together as a “mechanical muse” of sorts – surprisingly alluring – and, like a physical automaton can serve as a symbol – a microcosm – of what the MSTM sees (at the very least in practice) as the cosmic machine, our “final frontier”. And yet, individuals who unreflectively participate in these things – giving themselves over to them and seeking the powers afforded by the technology apart from technology’s rightful purposes – in fact yield to the same pragmatism and reductionism those wielding them are captive to. Thus, they ultimately nullify themselves philosophically, politically, and economically – their value increasingly being only the data concerning their persons, and its perceived usefulness. Likewise libraries, the time-honored place of, and symbol for, the intellectual flowering of the individual, will, insofar as they spurn the classical liberal arts (with the idea that things are intrinsically good, and in the case of humans, special as well) in favor of the alluring embrace of MSTM-driven “information technology” and Big data - unwittingly contribute to their irrelevance and demise as they find themselves increasingly less needed, valued, wanted. Likewise for the liberal arts as a whole, and in fact history itself, if the acid of a “science” untethered from what is, in fact, good (intrinsically), continues to gain strengt
Simulating switchgrass aboveground biomass and production costs in eastern Canada with the Integrated Farm System Model
Get PDFSwitchgrass (Panicum virgatum L.) is a herbaceous perennial grass that can be used as bedding for livestock, planted in buffer strips, and used as biofuel but it is still not widely grown in eastern Canada. The objectives of this study were to verify the performance of the Integrated Farm System Model (IFSM) in simulating switchgrass growth and to estimate its yield potential and production cost in Eastern Canada. The performance of the IFSM was assessed with dry matter (DM) yield of switchgrass (cv. Cave-in-Rock) measured over three growing seasons (2015 to 2017) in southern Quebec, Canada. The model performed reasonably well with normalized root mean square errors of 19.5% for calibration and 27.9% for validation. Simulation results of potential yield and economic management over the long-term (1986 to 2015) for five switchgrass production sites in Eastern Canada indicated that average DM yields in Quebec City and Fredericton (9.6 and 9.7 t ha-1, respectively) were significantly lower than average DM yields in Saint-Hubert, Ottawa, and London (10.8, 10.4, and 11.0 t ha-1 respectively). Average annual production costs per tonne of DM for the spring harvest were higher at low-yield sites (64.50 for Fredericton and Quebec City, respectively) than at high-yield sites (62.82, and $60.08 for Saint-Hubert, Ottawa, and London, respectively). The IFSM-estimated production costs were within the range of the calculated values reported in other agro-economic analyses conducted in Ontario and Quebec.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Caribbean Report 22-01-1998
No full textThe Chief Ministers of Britain's dependent Caribbean territories meet in Bermuda to plan a united front for their upcoming conference in Britain. Additionally, there is a mid-February meeting planned with the British Foreign Secretary Robin Cook. Anguilla's Chief Minister Hubert Hughes argues that London should devolve more power to the political representatives and deliver more economic development. However, Jamaican politician Delroy Chuck disagrees on the issue of more control. The US has criticised proposals put forward by the EU to change its rules on banana imports from developing countries. As tens of thousands of Cubans attend the first ever mass by a Pope in Cuba, Pope John Paul II calls for religious education in schools in Cuba. Ironically, the US is well-represented in Cuba during this visit as Senator Jesse Helms, co-author of the Helms Burton legislation sent a delegation. Marc Thiessen comments on why Helms put a stamp of approval on the papal visit since he is an ardent proponent of the isolation of Cuba. In Guyana, CARICOM Chairman Dr. Keith Mitchell met with the political parties and spoke to the media about exercising sensitivity and responsibility when reporting about events in Guyana.1.

The impacts of short break provision on disabled children and families: an international literature review
No full textFor over 30 years, short breaks have been part of the landscape of support provision for families with a disabled child. Historically, the term ‘respite care’ has been used in much of the research literature concerning short breaks for families with a disabled child. However, ‘short breaks’ has become the preferred term, partly due to the negative connotations of family carers requiring ‘respite’ from their children, and partly because short breaks now encompass a much wider range of supports than out-of-home placement in specialist residential facilities (Cramer and Carlin, 2008). As such, the term ‘short breaks’ will be used throughout this review, with the exception of direct quotes from research studies where the term ‘respite’ is used by study participants or study authors
Compatible Buffer for Capillary Electrophoresis and Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry
Get PDFA compatible buffer system for the coupling of capillary electrophoresis (CE) with matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) was developed. The employed interface consists of a robot to drive a sliver-covered separation capillary and an AnchorChip MALDI-MS target. The outlet of the capillary is grounded and connected to the pre-deposited buffer droplet on the MALDI target to make the electric connection and allow sample crystallization for MALDI-MS. The possibility of using only one buffer already containing the matrix for MALDI-MS for the separation and the ionization was investigated and tested on protein and peptide samples. The results show that the proposed buffer system is suitable for CE-MALDI-MS coupling, simplifies the traditional buffer mixing steps in off-line CE-MALDI-MS protocols, and is therefore highly promising for on-line analysis.LEP
