Abstract The article discusses an interdisciplinary project aimed at highlighting the acoustical heritage of wetlands, by means of field recordings and a novel time-lapse montage method. We discuss a site-specific sound installation that was designed using original wetlands field recordings, live processing, and spatial audio multi-channel reproduction. The discussion focuses on spatial and temporal features of different types of recorded wetlands soundscapes. Future developments of this project will consider the implementation of a standalone spatiotemporal application, to be used in the context of virtual reality applications, game audio, and interactive dance performance.

The Way

This paper describes the background and development of a sound installation which, over a period of time, brings together site-specific field recordings, and acoustic and amplified sounds in a complex of natural and technological sources. During the installation diverse genres of recording and territories of sound become potentially, transiently available as local birdsong, background noises and the sounds of recordings and audio technologies are realised through enculturated experiences of recordings and ambient modes of listening. The work has closely evolved out of an existing field recording practice and the version described here remains a proposal – at the time of writing – to be completed in spring 2011. The way in which the installation has contingently emerged has become a critical part of the work which – instead of being conceived of as a untransferable ‘new reality’ essentially related to a site – will be used to open and connect recorded sound to the prolific wider circulation of mediated sound and – across different milieux – to the world ‘itself’.

AbstractThis article takes a site-specific, interactive sound installation called Pleasure Garden as a space for thinking about contemporary forms of musical experience. I develop a relational account of the ‘co-reception’ of Pleasure Garden, not centred on listening subjects, but distributed across audience members, artists, researchers and the more-than-human assemblage of the installation itself. I also discuss the effects of several overlapping cultures of ‘audiencing’ associated with Western art music, sound art and other forms of cultural experience – variously individualistic, distracted and participatory – characteristic of late capitalism. Tracing how Pleasure Garden both responded to and was interrupted by these wider forces, I take this case as suggestive of a deep ambivalence: that musical experience is at once powerfully conditioned and generatively uncertain. Throughout the article, problems of method, interpretation and representation intertwine, raising questions about how to study forms of musical experience that evade conventional ethnographic enquiry.

Abstract Background Astral microtubules emanating from the mitotic centrosomes play pivotal roles in defining cell division axis and tissue morphogenesis. Previous studies have demonstrated that human transforming acidic coiled-coil 3 (TACC3), the most conserved TACC family protein, regulates formation of astral microtubules at centrosomes in vertebrate cells by affecting γ-tubulin ring complex (γ-TuRC) assembly. However, the molecular mechanisms underlying such function were not completely understood. Results Here, we show that Aurora A site-specific phosphorylation in TACC3 regulates formation of astral microtubules by stabilizing γ-TuRC assembly in human cells. Mutation of the most conserved Aurora A targeting site, Ser 558 to alanine (S558A) in TACC3 results in robust loss of astral microtubules and disrupts localization of the γ-tubulin ring complex (γ-TuRC) proteins at the spindle poles. Under similar condition, phospho-mimicking S558D mutation retains astral microtubules and the γ-TuRC proteins in a manner similar to control cells expressed with wild type TACC3. Time-lapse imaging reveals that S558A mutation leads to defects in positioning of the spindle-poles and thereby causes delay in metaphase to anaphase transition. Biochemical results determine that the Ser 558- phosphorylated TACC3 interacts with the γ-TuRC proteins and further, S558A mutation impairs the interaction. We further reveal that the mutation affects the assembly of γ-TuRC from the small complex components. Conclusions The results demonstrate that TACC3 phosphorylation stabilizes γ- tubulin ring complex assembly and thereby regulates formation of centrosomal asters. They also implicate a potential role of TACC3 phosphorylation in the functional integrity of centrosomes/spindle poles.

This article describes an innovative compositional method based on the use of a sonic time-lapse algorithm to create soundscape audio montages. The method is based on the superposition of short audio samples of 24-hour continuous field recordings carried out in various kinds of wildlife sonic environments. The optimisation of the algorithm focused on the enhancement of gradual crossfade transitions between recorded samples and the use of variable sample durations as a way of recreating a natural sense of evolution of sonic events in time. Future developments of the project will integrate virtual reality interfaces and environmental education projects as part of the time-lapse algorithm machine-learning techniques and also creative tools suitable for multimedia installations.

Stalled Fork

The completion of genome duplication during the cell cycle is threatened by the presence of replication fork barriers (RFBs). Following collision with a RFB, replication proteins can dissociate from the stalled fork (fork collapse) rendering it incapable of further DNA synthesis unless recombination intervenes to restart replication. We use time-lapse microscopy and genetic assays to show that recombination is initiated within ∼10 min of replication fork blockage at a site-specific barrier in fission yeast, leading to a restarted fork within ∼60 min, which is only prevented/curtailed by the arrival of the opposing replication fork. The restarted fork is susceptible to further collapse causing hyper-recombination downstream of the barrier. Surprisingly, in our system fork restart is unnecessary for maintaining cell viability. Seemingly, the risk of failing to complete replication prior to mitosis is sufficient to warrant the induction of recombination even though it can cause deleterious genetic change.

Temporal Features

This article describes two site-specific sound installations conceived as part of interdisciplinary collaborations which aimed to explore different acoustic and perceptual features of urban and rural landscapes. The creative process involved in the design and implementation of both installations is described, focusing on the organic montage techniques based on spatial and temporal features of field recording methods. Future developments of the works will consider ways of developing further spatial-temporal sampling methods to assess particular features of soundscapes by panels of trained listeners.
