Sounds from the empty city : a practice-led case study in the confluence of music, narrative and emotion

The creative practice: the adaptation of picture book The Empty City (Megarrity/Oxlade, Hachette 2007) into an innovative, interdisciplinary performance for children which combines live performance, music, projected animation and performing objects. The researcher, in the combined roles of writer/composer proposes deliberate experiments in music, narrative and emotion in the various drafts of the adaptation, and tests them in process and performance product. A particular method of composing music for live performance is tested in against the emergent needs of a collaborative, intermedial process. The unpredictable site of research means that this project is both looking to address both pre-determined and emerging points of inquiry. This analysis (directed by audience reception) finds that critical incidents of intermediality between music, narrative, action and emotion translate directly into highlights of the performance.

Reproducibility of scratch assays is affected by the initial degree of confluence: Experiments, modelling and model selection

Scratch assays are difficult to reproduce. Here we identify a previously overlooked source of variability which could partially explain this difficulty. We analyse a suite of scratch assays in which we vary the initial degree of confluence (initial cell density). Our results indicate that the rate of re-colonisation is very sensitive to the initial density. To quantify the relative roles of cell migration and proliferation, we calibrate the solution of the Fisher–Kolmogorov model to cell density profiles to provide estimates of the cell diffusivity, D, and the cell proliferation rate, λ. This procedure indicates that the estimates of D and λ are very sensitive to the initial density. This dependence suggests that the Fisher–Kolmogorov model does not accurately represent the details of the collective cell spreading process, since this model assumes that D and λ are constants that ought to be independent of the initial density. Since higher initial cell density leads to enhanced spreading, we also calibrate the solution of the Porous–Fisher model to the data as this model assumes that the cell flux is an increasing function of the cell density. Estimates of D and λ associated with the Porous–Fisher model are less sensitive to the initial density, suggesting that the Porous–Fisher model provides a better description of the experiments.

L’architecture engagée du «Case Study House Program» de la revue Arts and Architecture de 1945 – 1966 : une confluence génératrice

La conception architecturale du logis, individuel ou collectif, est un défi majeur pour les architectes depuis l'avènement de la modernité. Au début du 21ième siècle, la multiplicité des conditions démographiques et celle de la mobilité des personnes sous-tendent la complexité de l'élaboration de prototypes ou de modèles d'habitation. Que peut-on apprendre des expériences menées dans ce domaine après la seconde guerre mondiale aux États-Unis ? Ce mémoire de maîtrise est consacré à l'étude d’un cas particulier celui du programme de création architecturale réalisée en Californie de 1945 à 1966, connu sous le nom de : «Case Study House Program». Ce programme, dirigé par John Entenza, éditeur de la revue Arts and Architecture, rassemblait de nombreux architectes dont les plus célèbres sont Charles et Ray Eames, Richard Neutra, Craig Ellwood et Pierre Koenig, tous auteurs de maisons modernes devenues oeuvres canoniques dans l’histoire de l’architecture. L'analyse détaillé de ce cas et de ses retombées devrait permettre de mieux cerner les aspects suivants: la portée critique du CSHP (case study house program) qui s'opposait aux modèles dominants du marché immobilier, modèles généralement inspirés de styles traditionnels; le potentiel et les limites d'une telle démarche face à la demande sociale; la dimension anticipatrice des propositions du CSHP pour la conception de logis mieux adaptés aux besoins du 21ième siècle, en particulier ceux qui découlent des changements démographiques et de la mobilité géographiques des personnes; la valeur d'exemple du CSHP pour mieux comprendre les fondements de la résistance du public aux innovations architecturales, autant du point de vue technique que du point de vue esthétique.

Multiyear measurements of the oceanic and atmospheric boundary layers at the Brazil-Malvinas confluence region

This study analyzes and discusses data taken from oceanic and atmospheric measurements performed simultaneously at the Brazil-Malvinas Confluence (BMC) region in the southwestern Atlantic Ocean. This area is one of the most dynamical frontal regions of the world ocean. Data were collected during four research cruises in the region once a year in consecutive years between 2004 and 2007. Very few studies have addressed the importance of studying the air-sea coupling at the BMC region. Lateral temperature gradients at the study region were as high as 0.3 degrees C km(-1) at the surface and subsurface. In the oceanic boundary layer, the vertical temperature gradient reached 0.08 degrees C m(-1) at 500 m depth. Our results show that the marine atmospheric boundary layer (MABL) at the BMC region is modulated by the strong sea surface temperature (SST) gradients present at the sea surface. The mean MABL structure is thicker over the warmside of the BMC where Brazil Current (BC) waters predominate. The opposite occurs over the coldside of the confluence where waters from the Malvinas (Falkland) Current (MC) are found. The warmside of the confluence presented systematically higher MABL top height compared to the coldside. This type of modulation at the synoptic scale is consistent to what happens in other frontal regions of the world ocean, where the MABL adjusts itself to modifications along the SST gradients. Over warm waters at the BMC region, the MABL static instability and turbulence were increased while winds at the lower portion of the MABL were strong. Over the coldside of the BC/MC front an opposite behavior is found: the MABL is thinner and more stable. Our results suggest that the sea-level pressure (SLP) was also modulated locally, together with static stability vertical mixing mechanism, by the surface condition during all cruises. SST gradients at the BMC region modulate the synoptic atmospheric pressure gradient. Postfrontal and prefrontal conditions produce opposite thermal advections in the MABL that lead to different pressure intensification patterns across the confluence.

Price exhaustion and number preference : time and price confluence in Australian stock prices

Confluence occurs when different trading filters generate signals that point to the same directional move. Using regression analysis, this paper investigates confluence trading signals associated with number preference and price exhaustion, for a sample of Australian stocks. The results show that certain price levels tend to act as psychological barriers, and that price exhaustion signals are a real phenomenon in the Australian stock market. It is shown also that confluence exists in the Australian stock market. Importantly, confluence is associated with price retracements that are of economic and statistical significance, offering profitable trading opportunities. The results suggest that Australian stocks do not follow a random walk.

This story wants to be danced : creative writing, dance, convergence and confluence

I suggest ways the discipline of dance can enrich and challenge the discipline of creative writing. I focus particularly on improvisation in dance, relating this to creative writing pedagogy, classroom structure and activities. Much possibility exists in utilising moments when creative arts disciplines touch. How might creative writers and creative writing courses use such fusions? I draw on material theory and briefly upon transformative and collaborative education theories in my exploration of these ideas.

Use of recent geoid models to estimate mean dynamic topography and geostrophic currents in South Atlantic and Brazil Malvinas confluence

The use of geoid models to estimate the Mean Dynamic Topography was stimulated with the launching of the GRACE satellite system, since its models present unprecedented precision and space-time resolution. In the present study, besides the DNSC08 mean sea level model, the following geoid models were used with the objective of computing the MDTs: EGM96, EIGEN-5C and EGM2008. In the method adopted, geostrophic currents for the South Atlantic were computed based on the MDTs. In this study it was found that the degree and order of the geoid models affect the determination of TDM and currents directly. The presence of noise in the MDT requires the use of efficient filtering techniques, such as the filter based on Singular Spectrum Analysis, which presents significant advantages in relation to conventional filters. Geostrophic currents resulting from geoid models were compared with the HYCOM hydrodynamic numerical model. In conclusion, results show that MDTs and respective geostrophic currents calculated with EIGEN-5C and EGM2008 models are similar to the results of the numerical model, especially regarding the main large scale features such as boundary currents and the retroflection at the Brazil-Malvinas Confluence.
