    Get PDF
    The published texts and curatorial practice collected together in this PhD interrogate the nature of the creative act in contemporary visual art practices. They focus on the complex of co-creation in relation to: - creative acts of dialogue between the practices of artists, curators and writers - creative acts of experiencing the world - creative acts of making art about experiencing. They form a coherent programme of research addressing: - site-based and contextually engaged curated projects since the 1950s - relationships between, and definitions of, the roles of curator, writer and artist in contemporary practices - the nature of authorship and collaboration - histories, theories and practices around Body Art and Land Art - current philosophical and scientific debates around consciousness - the situated, immersive and creative nature of embodied consciousness - writing practices that address consciousness and experience. The material draws, in particular, on the ideas and work of James Joyce and Marcel Duchamp, as well as a range of other thinkers including Georges Bataille, Rosalind Krauss, Mary Douglas, Francisco Varela and Elaine Scarry. Section 1 Includes materials and discussion of independent site-based curatorial projects In the UK including New British Sculpture, Edge 90, Edge 92, TSWA, Tyne International, Artscape Nordland and Artangel. Artists discussed include Helen Chadwick, Cornelia Parker, Guillermo Gomez Pena & Coco Fusco, Maria Thereza Alves, Alan Michelson & Jimmie Durham. This section also includes articles on Marina Abramovic, Dorothy Cross and Carolee Schneemann. Section 2 includes materials and discussion of curatorial and writing projects concerned with the nature of experience and embodied consciousness. This includes the projects EarthWire with artists Kathleen Rogers, Rena Tangens, Jozefa Rogocki and Bruce Gilchrist, James Turrell's Northumberland Skyspace and Twilight It also includes writings on the artist's body, embodied consciousness, documentation and performance, James Turrell, Heather Ackroyd and Dan Harvey, Chris Burden, Joan Jonas and Cyril Lepetit. Section 3 considers embodied consciousness immersed in its environment and the work of artists addressing this theme. It includes the curatorial projects Here, Contemporary Romantic and the sound art festival OX' with artists including Ray Lee and Alexel Shulgin, the exhibition projects KnoWhere, Generator and Dialogue and writings on art and weather, women's art, KnoWhere, Marcus Coates, London Fieidworks and Optik

    The Gulf Stream Dynamics Experiment: Inverted Echo Sounder Data Report for the April 1983 to June 1984 Deployment Period

    Get PDF
    The Gulf Stream Dynamics Experiment was conducted in the region just northeast of Cape Hatteras from September 1983 to May 1985 to study the propagation and growth characteristics of Gulf Stream meanders. Data collected as part of the field experiment included inverted echo sounders, current meter moorings, and AXBT survey flights. This report documents the inverted echo sounder data collected from September 1983 to June 1984, as well as additional measurements made from April to September 1983. Time series plots of the half-hourly travel time and low-pass filtered thermocline depth measurements are presented for twenty-two instruments. Bottom pressure and temperature, measured at seven of the sites, are also plotted. Basic statistics are given for all the data records shown. maps of the thermocline depth field in a 240 km by 460 km region are presented at daily intervals

    On Gulf Stream meander characteristics near Cape Hatteras

    From 1979 to 1982, Gulf Stream path fluctuations within 375 km downstream of Cape Hatteras, North Carolina, have been monitored by inverted echo sounders. Histograms of the north wall locations along four cross‐stream sections change shape and increase in range dramatically downstream through the study area: Near Cape Hatteras, the histogram is peaked with the Gulf Stream found over half of the time within a narrow 10‐km range. The distributions become progressively more symmetric and the ranges widen downstream such that in the eastern portion of the study area the Gulf Stream can be found with equal probability throughout its 145‐km excursion range. From the 36‐month‐long time series near 73°W there is evidence of a seasonal cycle of Gulf Stream positions; northerly locations occur in the summer/fall, when transports are lower, and southerly locations occur in the winter/spring, when transports are higher. An observational dispersion relationship is presented for meander propagation and growth: Downstream propagation rates increase smoothly from about 14 km d−1 for meanders with periods and wavelengths (33 days, 460 km) to over 45 km d−1 for the (4 days, 180 km) meanders. Meander amplitudes show rapid growth rates in two separate bands, near (4–5 days, 180–230 km) and (10–33 days, 300–500 km)

    Identifying and supporting young adolescent academic underachievers in year 7 and 8 classrooms

    Academic underachievement in young adolescents has been a concern for teachers, schools and systems for some time. In Australian schools, curriculum reforms and middle years programs have been implemented to improve the educational outcomes of young adolescents, and address underachievement, with limited continuity and consistency. This study used a mixed methods approach within a collective case study to investigate characteristics and practices of secondary school teachers when identifying and dealing with academic underachievers in Years 7 and 8. Findings revealed that teachers identified the following as primary indicators of an academic underachiever: literacy and numeracy barriers; absences; family background factors; and, a lack of engagement, participation and confidence in learning. These teachers implemented specific practices to help address student underachievement including attempting to improve pedagogical relationships, collaboration with colleagues, aides and parents, and adjusting and modifying curriculum. The findings showed that these practices were not consistently informed by learner-centred or middle years educational models, but tended to be practical responses provided to assist underachieving students participate in learning activities and assessment and to meet age and stage curriculum standards. Teachers believed their practices were negatively influenced and limited by lack of time, system support and resources. While recognising that academic underachievers had complex needs, the practices teachers employed in the classroom were generally remedial and did not necessarily encourage the development of learner confidence in their students

    The SYNOP Experiment: Thermocline Depth Maps for the Inlet Array October 1987 to August 1990

    Get PDF
    Between October 1987 and August 1990, two arrays of inverted echo sounders were deployed in the Gulf Stream northeast of Cape Hatteras as part of the SYNoptic Ocean Prediction Experiment. The Inlet Array consisted of 9 inverted echo sounders (IES). Centered at 74oW, the Inlet Array was designed to measure key parameters that describe the Gulf Stream path variability near Cape Hatteras. The large Central Array of 24 IESs was centered on the current near 68oW, about 400 km downstream of the Inlet Array. Spanning nearly 300 km in both the cross-stream and downstream directions, the Central Array was designed to monitor the thermocline structure of the Gulf Stream in the region of large meanders and frequent ring interactions. Using objective analysis, we have mapped the Gulf Stream thermal field measured by the IESs in the Inlet Array. In this report, the objective analysis technique is described and the mapping parameters are documented. Daily maps of the thermocline depth field are presented for the period 14 October 1987 through 31 August 1990

    Cofilin Activation in Peripheral CD4 T Cells of HIV-1 Infected Patients: A Pilot Study

    Get PDF
    Cofilin is an actin-depolymerizing factor that regulates actin dynamics critical for T cell migration and T cell activation. In unstimulated resting CD4 T cells, cofilin exists largely as a phosphorylated inactive form. Previously, we demonstrated that during HIV-1 infection of resting CD4 T cells, the viral envelope-CXCR4 signaling activates cofilin to overcome the static cortical actin restriction. In this pilot study, we have extended this in vitro observation and examined cofilin phosphorylation in resting CD4 T cells purified from the peripheral blood of HIV-1-infected patients. Here, we report that the resting T cells from infected patients carry significantly higher levels of active cofilin, suggesting that these resting cells have been primed in vivo in cofilin activity to facilitate HIV-1 infection. HIV-1-mediated aberrant activation of cofilin may also lead to abnormalities in T cell migration and activation that could contribute to viral pathogenesis.Department of Defense (National Defense Science and Engineering Fellowship); National Institute of Allergy and Infectious Diseases (AI069981
