Voice in devising/devising through voice: A conversation with Mikhail Karikis, Elaine Mitchener and Jessica Walker

This is the author accepted manuscript. The final version is available from the publisher via the DOI in this record.How is voice used in devising practices? What is the interplay between structure, freedom and improvisation in such compositional practices? In what ways is voice conceived and practised as material? In providing answers to such questions, this multi-vocal interview/roundtable transcript is composed around the responses of three contemporary vocal artists based in the United Kingdom, Mikhail Karikis, Elaine Mitchener and Jessica Walker. Their work ranges from audio-visual installations and solo shows to immersive performance and site-responsive work, and their deployment of vocality ranges from jazz and Victorian music hall repertoires to extended vocal techniques and experimentations across the speech–song continuum. In conversation with practitioner-scholar Konstantinos Thomaidis, their responses offer valuable insights into current vocal experimentation but are also an invitation to expand discussions around devising in the field of interdisciplinary voice studies

A sensory sociology of the future: Affect, hope and inventive methodologies

The starting point for this article is that the future is difficult to research because of its intangibility. Drawing on recent work in visual and sensory sociology, affect, and time and futurity, I propose that sensory methodologies provide some ways of grasping, understanding, attuning and relating to the future. To develop this argument, I pay close attention to the Children of Unquiet (2013-14) project by artist Mikhail Karikis, and especially the film of the same name. This project involved Karikis working with local children to probe the possible futures of a site that was invested with hope and progress in the twentieth century, but has since been depopulated. In turning to an art project to consider the developments of a sensory sociology of the future, my intention is to examine the resonances between the project and some of the concerns of a sensory sociology of the future. In particular, I discuss the participation of children, and a conceptualization of hope as potentiality, open, affective and in the present. In conclusion, I explicate how the article seeks to contribute to a sensory sociology of the future, not by providing a blueprint for further work but rather by offering some indicative points and coordinates for this emerging field of research, including its involvement in creating conditions through which possible futures might be provoked or invented

Anterior cruciate ligament reconstruction is associated with greater tibial tunnel widening when using a bioabsorbable screw compared to an all-inside technique with suspensory fixation

Purpose: To compare clinical outcomes and tunnel widening following anterior cruciate ligament reconstruction (ACLR) performed with an all-inside technique (Group A) or with a bioabsorbable tibial screw and suspensory femoral fixation (Group B). Methods: Tunnel widening was assessed using computed tomography (CT) and a previously validated analytical best fit cylinder technique at approximately 1-year following ACLR. Clinical follow-up comprised evaluation with IKDC, KSS, Tegner, Lysholm scores, and knee laxity assessment. Results: The study population comprised 22 patients in each group with a median clinical follow-up of 24 months (range 21–27 months). The median duration between ACLR and CT was 13 months (range 12–14 months). There were no significant differences in clinical outcome measures between groups. There were no differences between groups with respect to femoral tunnel widening. However, there was a significantly larger increase in tibial tunnel widening, at the middle portion, in Group B (2.4 ± 1.5 mm) compared to Group A (0.8 ± 0.4 mm) (p = 0.027), and also at the articular portion in Group B (1.5 ± 0.8 mm) compared to Group A (0.8 ± 0.8 mm) (p = 0.027). Conclusion: Tibial tunnel widening after ACLR using hamstring tendon autograft is significantly greater with suspensory femoral fixation and a bioabsorbable tibial interference screw when compared to an all-inside technique at a median follow-up of 2 years. The clinical relevance of this work lies in the rebuttal of concerns arising from biomechanical studies regarding the possibility of increased tunnel widening with an all-inside technique.

A self-assembly study of PNA-porphyrin and PNA-BODIPY hybrids in mixed solvent systems

In this work a peptide nucleic acid (PNA) was covalently connected with two different chromophores, namely porphyrin and boron-dipyrromethene. To the best of our knowledge, this is the first example in the literature where a PNA unit is covalently linked to such chromophores. The self-assembly properties of the hybrids were examined through electron microscopy experiments by adopting the &quot;good-bad&quot; solvent self-assembly protocol. For both hybrids (PNA-TPP and PNA-BDP) we were able to observe distinctive supramolecular architectures. During these studies we investigated the influence of the solvent system, the concentration and the deposition method on the morphology of the formed nanostructures. In the case of PNA-TPP under all examined conditions well-formed nanospheres were obtained. Interestingly, in the PNA-BDP hybrid by simply altering the solvent mixture, self-assemblies of two different morphologies were formed (spherical and flake shaped). Absorption and emission studies suggested the formation of J-aggregates in all the obtained nanostructures. The nano-architectures assembled by PNA conjugates are capable of light-harvesting and producing hydrogen using Pt nanoparticles as a photocatalyst.</p
