Representing the Change: Rules of Engagement
Drawing on practice rooted in regeneration contexts with a focus on housing and development, this lab aims to reveal the challenging situations artists find themselves in when managing complex projects. When under pressure to demonstrate impact, notions of success for artists working in precarious contexts can be difficult to define.
In this lab delegates are invited to unpick the rhetoric and image of ‘successful’ community based arts programming and explore alternative criteria for reviewing practice. The lab will aim to create a space for truthful, supported exchange around a need for transparency in the ways that artists are working in order to demand greater support for the practice. Guest artists Rebecca Davies and Dan Russell will join Anna Francis in facilitating the lab.
The lab was delivered as part of The Social Art Summit.
'An Artist-Led Review of Socially Engaged Arts Practice in the UK & beyond.
Convened by Social Art Network, Sheffield.
Over two-days artists from around the country will come together to share practice, showcase work and explore what it means to be making art through social engagement right now.
Artists, activists, community groups, curators, students, academics, funders and sectors working in the social realm are invited to join the conversation through a series of events at Site Gallery and other venues around the city. Through building a network, showcasing practice and expanding dialogue the Summit will develop agency in the field of art and social practice and test the ground for launching a Social Art Biennale in 2020.
International guests include Black Quantum Futurism and Interference Archive.
Flight testing of a luminescent surface pressure sensor
NASA ARC has conducted flight tests of a new type of aerodynamic pressure sensor based on a luminescent surface coating. Flights were conducted at the NASA ARC-Dryden Flight Research Facility. The luminescent pressure sensor is based on a surface coating which, when illuminated with ultraviolet light, emits visible light with an intensity dependent on the local air pressure on the surface. This technique makes it possible to obtain pressure data over the entire surface of an aircraft, as opposed to conventional instrumentation, which can only make measurements at pre-selected points. The objective of the flight tests was to evaluate the effectiveness and practicality of a luminescent pressure sensor in the actual flight environment. A luminescent pressure sensor was installed on a fin, the Flight Test Fixture (FTF), that is attached to the underside of an F-104 aircraft. The response of one particular surface coating was evaluated at low supersonic Mach numbers (M = 1.0-1.6) in order to provide an initial estimate of the sensor's capabilities. This memo describes the test approach, the techniques used, and the pressure sensor's behavior under flight conditions. A direct comparison between data provided by the luminescent pressure sensor and that produced by conventional pressure instrumentation shows that the luminescent sensor can provide quantitative data under flight conditions. However, the test results also show that the sensor has a number of limitations which must be addressed if this technique is to prove useful in the flight environment
Ecological and Genomic Attributes of Novel Bacterial Taxa That Thrive in Subsurface Soil Horizons.
While most bacterial and archaeal taxa living in surface soils remain undescribed, this problem is exacerbated in deeper soils, owing to the unique oligotrophic conditions found in the subsurface. Additionally, previous studies of soil microbiomes have focused almost exclusively on surface soils, even though the microbes living in deeper soils also play critical roles in a wide range of biogeochemical processes. We examined soils collected from 20 distinct profiles across the United States to characterize the bacterial and archaeal communities that live in subsurface soils and to determine whether there are consistent changes in soil microbial communities with depth across a wide range of soil and environmental conditions. We found that bacterial and archaeal diversity generally decreased with depth, as did the degree of similarity of microbial communities to those found in surface horizons. We observed five phyla that consistently increased in relative abundance with depth across our soil profiles: Chloroflexi, Nitrospirae, Euryarchaeota, and candidate phyla GAL15 and Dormibacteraeota (formerly AD3). Leveraging the unusually high abundance of Dormibacteraeota at depth, we assembled genomes representative of this candidate phylum and identified traits that are likely to be beneficial in low-nutrient environments, including the synthesis and storage of carbohydrates, the potential to use carbon monoxide (CO) as a supplemental energy source, and the ability to form spores. Together these attributes likely allow members of the candidate phylum Dormibacteraeota to flourish in deeper soils and provide insight into the survival and growth strategies employed by the microbes that thrive in oligotrophic soil environments.IMPORTANCE Soil profiles are rarely homogeneous. Resource availability and microbial abundances typically decrease with soil depth, but microbes found in deeper horizons are still important components of terrestrial ecosystems. By studying 20 soil profiles across the United States, we documented consistent changes in soil bacterial and archaeal communities with depth. Deeper soils harbored communities distinct from those of the more commonly studied surface horizons. Most notably, we found that the candidate phylum Dormibacteraeota (formerly AD3) was often dominant in subsurface soils, and we used genomes from uncultivated members of this group to identify why these taxa are able to thrive in such resource-limited environments. Simply digging deeper into soil can reveal a surprising number of novel microbes with unique adaptations to oligotrophic subsurface conditions
Is older goodwill value relevant?
Although previous research has generally found that goodwill reported in firms' financial reports is relevant to equity valuation, no known studies have directly examined whether the value-relevance of purchased goodwill holds as it ages. We examine this issue in the Australian context to determine whether the market attaches different values to the components of Australian firms' goodwill when it is disaggregated into different 'ages'. Our results suggest that recently acquired goodwill has information content whereas 'older' goodwill does not. Our findings have implications for goodwill accounting practice and recent changes to goodwill accounting standards. © 2006 AFAANZ
