Audiovisual coherence and physical presence: I am there, therefore I am [?]
The following is an attempt at both documentation and discussion of my personal audiovisual practice to date; in particular my attempts over the past four years to bring a complex, largely algorithmic, fixed-media method into a live, improvisatory performance context
ic2 (formerly intervention:coaction)
ic2 is a live, audiovisual, beat-and-noise-based performance work. The intention is to create a symbiotic system, in which live decision-making by the performer impacts on both the audio and visual components of the work, but also in which both the audio and visual components can interact with one another, causing behaviours that are not directly controlled by the system performer. There is also an element of chaotic behaviour built into the system, causing unpredictable audio and visual outcomes
pletten
pletten: squash, crush, flatten.
pletten is a dual screen audiovisual work that is intended for playback on two opposite walls of a dark, square space but can also be exhibited side by side.
The work is an exploration of simultaneous compositional process and the development of complementary sonic and visual forms on a micro- and macro-structural level. The two screens should be displayed opposite one another, with the audience situated in the centre of the two, allowing them to engage with the sonic and visual structures being formed in a variety of ways
Indusium
indusium is an exploration of additive compositional process. Groups of material are added to and extended by step, the visuals reflecting the changing timbral colours caused through unexpected crossovers in pitch and rhythm
plavi
plavi is an audiovisual collaboration between composers Louise Harris and Jane Stanley, for Regeneration, an arts-science project inspired by stem cell biology and regenerative medicine; the proliferation of sonic and visual cells being reflective of regenerative biological processes
Two independent mechanisms for motion-in-depth perception : evidence from individual differences
Our forward-facing eyes allow us the advantage of binocular visual information: using the tiny differences between right and left eye views to learn about depth and location in three dimensions. Our visual systems also contain specialized mechanisms to detect motion-in-depth from binocular vision, but the nature of these mechanisms remains controversial. Binocular motion-in-depth perception could theoretically be based on first detecting binocular disparity and then monitoring how it changes over time. The alternative is to monitor the motion in the right and left eye separately and then compare these motion signals. Here we used an individual differences approach to test whether the two sources of information are processed via dissociated mechanisms, and to measure the relative importance of those mechanisms. Our results suggest the existence of two distinct mechanisms, each contributing to the perception of motion-in-depth in most observers. Additionally, for the first time, we demonstrate the relative prevalence of the two mechanisms within a normal population. In general, visual systems appear to rely mostly on the mechanism sensitive to changing binocular disparity, but perception of motion-in-depth is augmented by the presence of a less sensitive mechanism that uses interocular velocity differences. Occasionally, we find observers with the opposite pattern of sensitivity. More generally this work showcases the power of the individual differences approach in studying the functional organization of cognitive systems.Publisher PDFPeer reviewe

Pan African narratives: sites of resistance in the Black diaspora
Africa as a point of reference for Africans dispersed from her shores and their descendants in the Diaspora has perpetuated discourse of longing and ambivalence. For centuries these various sentiments have emerged in Black literary expressions. The quest of this study is to advance Black narrative tradition by proposing a theoretical framework informed by these constructs and predicaments to establish a genre of literature referred to here as Pan African narratives. This work looks at Black response to the dilemma of dispersal and dislocation in the Diaspora from the nineteenth to the twentieth century. More specifically, it examines the emergence of a literary genre at the juncture of the African diaspora and Pan African paradigms. Building on the legacy of slave and migration narratives, Pan African narratives reveal manifestations of Black solidarity and resistance to oppressive forces
Experiencing the research role of the consultant radiographer: a grounded theory study
Aim
The aim of this study was to explore what the core domain of research means to consultant radiographers in clinical practice and to identify the key factors that facilitate or hinder research activity by this staff group.
Design
Grounded theory research methodology was employed.
There were three phases to the study:
• Literature review.
• Electronic questionnaires to all those in consultant radiographer posts as identified by the Society and College of Radiographers consultant radiographer network.
• Twenty five consultant radiographers invited for telephone interview.
Results
Results indicate there are variations across clinical specialties as to the amount and level of research undertaken by consultant radiographers.
The principal barriers revealed were: lack of time; excessive clinical workload; lack of skills and confidence to undertake research; poor research culture; and lack of support.
The main facilitators noted were: dedicated time, research training and up-skilling; mutually beneficial collaborations; managerial understanding of the research domain of the role; and research focussed on clinical demand.
Conclusion
Research is one of the four core domains of consultant allied health professional and nursing roles but, as yet, it is not fully embedded into those of all consultant radiographers. Many consultant radiographers appear to spend more of their time on the ‘clinical expert’ element of their role at the expense of the research domain.
This research identified factors, from the consultant radiographers’ perspective, that both support and hinder research and suggests that, with ‘an intelligent overview’, some of barriers could be overcome. This study concludes that there is an urgent need for consultant radiographers to understand why research is one of the four core domains and to recognise the need to embed research into their clinical practice
