This paper is concerned with the collaborative design of a reverse logistics supply chain, the important back half of an organic waste circular economy in Sydney, Australia. Our effort goes against the grain of dominant economic logic. While there is a well-developed forward supply chain that gets food from farm to plate – facilitated by policies, market norms, practices and infrastructures – the reverse logistics of getting organic waste materials back into the soil is largely absent. Our corrective foray into redrawing the economy in circular terms involves diverting Sydney’s three thousand tonnes per annum of spent coffee grounds (SCG) and chaff (a by-product of coffee roasting) from landfill to farms. Doing so avoids greenhouse gas emissions that arise from rotting organic waste and, instead, contributes to regenerative farming practice and rural livelihoods.

The Dreams for Digital Spaces joint symposium paper was co-written to accompany the Dreams for Digital Spaces Representative Symposia presented at the American Educational Research Association (AERA) annual meeting held in Chicago, US, 14th April 2023. The paper provides further details of each of the four interrelated contributions and full, combined reference list. Abstract: Dreams for Digital Spaces Symposium explores the array of so-called truths that shape the digital worlds of children, educators, researchers, imaginaries, data, AI, algorithms and more through a series of four interconnected presentations involving research that takes up the digital as a focus and/or mode of inquiry. Together the presentations demonstrate the power of combining data science with philosophy, artistry, co-design, and educational research through interdisciplinary collaborations – collaborations which have folded in and out of each other as ideas, methods and even people have travelled. The symposium offers the audience an opportunity to consider how digital practices become the stuff of dreams and nightmares, making room for a multiplicity of potentially transformative truths to take place across virtual and physical sites.

In Part 1 of ‘Encountering Berlant’, we encounter the promise and provocation of Lauren Berlant's work. In 1000-word contributions, geographers and others stay with what Berlant's thought offers contemporary human geography. They amplify an encounter with their work, demonstrating how a concept, idea, or style disrupts something, opens up a new possibility, or simply invites thinking otherwise. The encounters range across the incredible body of work Berlant left us with, from the ‘national sentimentality’ trilogy through to recent work on negativity. Varying in form and tone, the encounters exemplify and enact the inexhaustible plenitude of Berlant's thought: fantasy, the case, love, impasse, feel tanks, slow death, ellipses, gesture, attrition, intimate public, ambivalence, style. Part 2 of ‘Encountering Berlant’ focuses on Berlant's most influential concept: ‘cruel optimism’. Across these heterogeneous encounters, Berlant's enduring concern with the tensions and possibilities of relationality and how to enact better forms of common life shine through. These enduring concerns and Berlant's commitment to the incoherence and overdetermination of phenomena are summarised in the Introduction, which also explores how Berlant's work has been engaged with in geography. The result is a repository of what an encounter with Berlant's thought makes possible.

This chapter reports on data generated through a process of COVID-19 attuned metho-pedagogical innovation established in the chapter "what are artists and art educators teaching us about how we can conceive and deliver teacher professional learning into the future?" Analysis of data reported in Coleman and MacDonald’s (2020) chapter articulates how movement between temporal and latent space enables teachers to attend to professional learning during times of COVID-19 driven interruption. The act of moving between the temporal and latent creates what can be described as Deleuzean slippage ; a productive act that yields new possibilities for becoming differently. This follow-up chapter reports data generated via a widened lens of slippage enacted by an expanded authorship team. In so doing, this chapter elicits an example of methodological and pedagogic interchange – with methodology and pedagogy mutually constituting each other, becoming metho-pedagogy. With a/r/tographic documentations of change occurring individually, collectively, and collaboratively, we propose slipperiness as a generative catalyst for change in pedagogic ways of knowing.

This project included a collaborative team from education, theatre and performance, and feminist and cultural studies. Building on pilot research in criminology, it looks at how theatre and interdisciplinary research can improve the wellbeing of young people in a climate of widespread violence against women. The project used a research-creation approach to examine how the play ‘Othello on Trial’: • Deploys theatre-based techniques that acknowledge diversity in the classroom • Queries assumptions about Shakespeare’s universality and colour-blindness. The project included performances informed by the research team’s collective practice and a symposium for invited stakeholders in the Victorian education sector. These events helped assess the project’s potential for inclusion in school-based curricula, and show the valuable contribution theatre can make to young people’s creativity, critical thinking and wellbeing. Resulting research data and resources will form a digital study to ensure the project’s longevity. This can be used by schools and policymakers in Australia and internationally. Note: Project outcomes reflect study adjustments to account for COVID-19 restrictions.

In this chapter I present a pedagogic encounter with an intense affective scene that occurred at a critical time in my PhD research. The encounter, which I call 'what happened to data and me', acts as an illustrative example of what may come from seeking out ways to account for contingency, complexity and contiguity by focussing on affect as a researchable phenomenon and affect as a productive force in a (post)qualitative inquiry. At the heart of 'what happened to data and me' is an unravelling of self, prompted by the realization of an onto-epistemological conflict between what my research was trying to do and how I, the researcher, was trying to go about the research. I invite the reader to return with me to 'the snap' and together witness how a snap experienced as a pedagogic encounter can create the conditions for transformative learning to occur-a learning that transforms an individual's relations with the world rendering them more capable. In conveying how 'what happened to data and me' rendered us (data, me, my supervisors, and more) more capable, I discuss how entering into artful relations with data can reconfigure the researcher-researched-research in affirming ways. I propose artful inquiry to do data in a way that accentuates the art of data, creating the conditions for data to transgress into da(r)ta. I conclude with six insights that researchers interested in 'the post' may like to consider. The intention is that hindsight will become foresight, not only highlighting what transgressive data can do but also drawing attention to the potential of critically and creatively engaging with the (post)qualitative inquiry.

Introduction: Hybrid epicardial and endocardial ablation has been proven to be an effective method for attaining rhythm control in persistent atrial fibrillation where anti-arrhythmic drug therapy and lone catheter ablation has been disappointing. We present mid-term findings on the safety and effectiveness of hybrid ablation in persistent atrial fibrillation. Method(s): Between 2017 and 2019, nineteen patients with persistent atrial fibrillation underwent totally thoracoscopic radiofrequency ablation with pulmonary vein isolation, posterior left atrial box lesion and left atrial appendage exclusion with Atriclip. They subsequently underwent endocardial mapping three months later. Any gaps from epicardial ablation were re-ablated. All patients were followed up prospectively. Result(s): Mean age of patients was 59.8+/-6.8 years. Median time of duration of atrial fibrillation preoperatively was 24 months. The average number of failed DCRs was 2.1+/-1.1. Average left atrial volume index was 55.45+/-11.5mL/m2. Average LVEF was 50.8+/-7.3%. At a mean follow-up of 395 days post hybrid ablation, all patients were in sinus rhythm at their most recent follow-up. 21% of patients had a recurrence of atrial arrhythmias. One patient had a minor complication of a left sided pleural effusion after the epicardial ablation. One patient had a pericardial effusion without tamponade requiring pericardiocentesis after epicardial ablation. There were no deaths, conversion to median sternotomy, strokes or pacemaker implantation. Conclusion(s): Sequential hybrid ablation for persistent atrial fibrillation is safe and effective.Copyright © 2020, CONFERENCE ABSTRACT

Background: By consensus statements, catheter ablation is a recommended treatment for patients with symptomatic drug-refractory paroxysmal atrial fibrillation (AF), as patients try to alleviate the burdensome AF symptoms that reduce the Quality of Life (QoL). Yet, first-line treatment of symptomatic patients via catheter ablation prior to initiation of antiarrhythmic drugs (AADs) is only a reasonable alternative (Class IIa). Clearly, more clinical data is necessary that compares catheter ablation to AAD therapy in treatment naive patients. Purpose(s): The Cryo-FIRST trial was designed to compare AAD treatment against pulmonary vein isolation (PVI) while using a cryoballoon catheter (Arctic Front Advance; Medtronic, Inc.). This current data analysis examines the QoL endpoints when comparing AADs to cryoballoon ablation in patients with symptomatic treatment naive paroxysmal AF. Method(s): This randomized multicenter trial enrolled 220 patients from 18 sites in 9 countries (Europe, Australia, and Latin America) in a prospective open-blinded endpoint study design. Patients had not been administered a class I or III AAD for longer than 48 hours for inclusion into the study. Subjects were randomized (1:1) into a cohort that was administered AAD therapy or a cohort that received PVI via cryoablation. The prespecified QoL endpoint at 12 months was measured using the Atrial Fibrillation Effect on Quality of Life (AFEQT) scores, and QoL recordings were taken at baseline, 1, 3, 6, 9, and 12 months following the index treatment. Result(s): Of the 218 patients randomized (age 52+/-13 years, 68% male) 86% completed the 12-month follow-up. Crossovers occurred in 9% of subjects (N=20), including: 1 subject in the cryoablation arm and 19 subjects in the AAD arm. At 12 months, 86.5% of the patients in the cryoablation arm and 70.4% of the patients in the AAD arm where without symptoms (EHRA score 1). The mean AFEQT summary score was more favorable in the catheter ablation group comp

Junctional ectopic tachycardia (JET) is a tachyarrhythmia arising from the atrioventricular node and His bundle area. Enhanced normal automaticity has been postulated as the mechanism of JET in the majority of patients. It is more common in children and can be seen as congenital or in postoperative settings. It is often a narrow complex tachycardia but can present as a wide complex tachycardia as a result of aberrant conduction. Its differentiation from other arrhythmias especially atrioventricular nodal reentrant tachycardia (AVNRT) can be challenging. Medical treatment of JET is difficult, and catheter ablation remains the mainstay of treatment in refractory cases with a high risk of atrioventricular block and recurrence.Copyright © 2020 The Authors.

Taking up Biesta's (2019) notion of a pedagogy of the world, we ask: How might participating in an arts-based educational program with/in a university enable young people from schools with low Index of Community Socio-Educational Advantage (ICSEA) values to encounter the world of higher education differently and become different in that encounter? This chapter comes from our engagement with empirical material generated during a (post)qualitative inquiry into the pedagogy of The Art of Engagement—a multi-arts studio program involving relational pedagogy and a/r/tography as curriculum located in SPACE, 1 whereby secondary school students from schools in less socio-educationally advantaged communities came together with undergraduate university students for a five-day intensive within a University of Melbourne breadth subject. The program's rationale was to connect with secondary school arts students completing their schooling in lower ICSEA value schools 2 through the design of authentic university encounters with/in site, practices and communities. It welcomed the secondary school students into the world of our university and enhanced their capacity to “be at home” in this world, creating the conditions for considering and potentially living different post-school futures.

The Gadfly first materialised as a provocative data performance at the Transitions Research Symposium held at The University of Melbourne in June 2017. The figuration of gadfly in the title shapes the figure of the researcher as (bothersome) questioner that provokes critical dialogue about the assumptions underpinning our own research practices and learning environments research more generally. This figuration provides us an entry point into working data through approaches offered by new materialist and post-qualitative research methods. The resulting data performance came together as a collaborative experiment inhabiting the in-between spaces of researchers, participants, research contexts, and ‘data’ initially generated in a Taekwondo training assemblage. Our collaborative approach involved an intra-active process as a way of doing data differently. Informing our process are concepts of intra-action, assemblage, affect, and sticky data.

The Cooling the Commons website is a deck of 41 illustrated patterns for cool commons. Cool commons are publicly accessible cool urban environments that offer an alternative to air-conditioned private spaces in cities where heat is compromising liveability. The website is a practical, open resource to facilitate design decision making in the context of urban heat adaptation.

This chapter extends the discussions of habit to the process of adapting to anthropogenically induced global warming. We reveal the role of designed practices, products and infrastructures in habituating urban populations to a changing climate. Our central concern is the ‘world within the world’ design has helped to create. In the rapidly densifying city, atmospheric commons are shaped and reshaped by human design; climate change is lived and felt in hostile heat islands and polluted, particulate-laden city air. Design offers a critical perspective on the dynamics that have shaped the city and organised the civic practices of its inhabitants. This ontological capacity is a second order agency rarely considered in the contexts in which design is most powerfully deployed to shape the materiality of the city. We apply ‘defuturing’ (Fry, 1999) as a critical deconstructive mode of reading to point to the designing relations shaping city atmospheres, infrastructures and modes of habituation. Our focus is the constellation of designing relations inaugurated by cooling technologies. At the same time as answering a primal need, cooling technologies also dehabituate us to the increasingly volatile conditions of our common world. In response, we seek to resuscitate the concept of ‘coolth’ as a critical term describing the experience and sensation of feeling (temperature) cool. We claim that designing for coolth cultivates habits of practice far better attuned to a warming world, recognising that climate-aware modes of dwelling must be both cultivated and habituated by design.

Introduction: Computed tomography pulmonary venogram can provide anatomic information of the left atrium, left atrial appendage and pulmonary veins that assist in planning radiofrequency catheter ablation for atrial fibrillation. Method(s): 26 patients underwent computed tomography pulmonary venograms prior to their hybrid atrial fibrillation ablation. Left atrial abnormalities, lack of left atrial appendage opacification, pulmonary vein ostial diameters and variant anatomy were recorded. Result(s): The mean pulmonary vein cross-sectional diameters were as follows: * Right superior pulmonary vein were 20.2+/-4.8mm x 17.8+/-4.3mm; * Right inferior pulmonary vein 19.6+/-3.9mm; * Left superior pulmonary vein 19.4+/-3.3mm x 16.1+/-2.9mm; and * Left inferior pulmonary veins 20.3+/-6.4mm x 16.4+/-3.5mm. There were 7 pulmonary vein variants. 3 patients had a common left pulmonary vein with a mean cross-sectional diameter of 33+/-2.6mm x 25.3+/-4 mm. 4 patients had right middle pulmonary veins with a mean cross-sectional diameter of 9+/-1.4mm x 8.5+/-1mm. There were no left atrial abnormalities. The left atrial appendages were well opacified. Conclusion(s): The pulmonary vein characteristics and variant anatomy were obtained. 29% of patients had variant anatomy, which is similar to the documented rates in the literature, with the most common variant being the right middle pulmonary vein.Copyright © 2020

Purpose: Since the introduction of the Biotronik Linox S/SD leads in 2006, there have been multiple reports of premature lead failure. The purpose of this study was to investigate the longevity of the Linox S/SD leads and to identify the possible predictors of lead failure in a single tertiary implant center. Method(s): We retrospectively reviewed patients who underwent implantation of Linox S/SD leads or Sorin Vigila 1CR/2CR leads (the same Linox S/SD leads marketed by Sorin) at our center. The cumulative lead survival was estimated using the Kaplan-Meier curve, and variables associated with lead failure were assessed by Cox proportional hazard model. Result(s): A total of 187 patients (154 (82%) male) underwent Linox S/SD or Vigila 1CR/2CR implantation between 2007 and 2013. During follow-up with a median time of 75 months, nine lead failures were identified (4.8%). The mean and median times from lead implantation to lead failure were 70.7 +/- 21 months and 64 (45-111) months, respectively. The cumulative survival probability for the Linox S/SD at 5 years was 97.1% and at 12 years was 90.3%. Non-physiological high-rate sensing was the most common type of lead failure in patients. In two-thirds of these patients, this led to inappropriate shock. We did not find any significant relationships between patients' clinical and procedural characteristics and lead failure. Conclusion(s): At our center, the 5-year lead survival of the Linox S/SD has been better than reports from other centers. The majority of lead failures presented as non-physiological high-rate sensing with subsequent inappropriate therapy.Copyright © 2020, Springer Science+Business Media, LLC, part of Springer Nature.

Introduction : Medical therapy for attaining rhythm control in longstanding persistent atrial fibrillation (AF) has been suboptimal. A novel hybrid thoracoscopic epicardial ablation and endocardial ablation has shown promising results in case series. We present mid-term findings on the safety and the effectiveness of hybrid epicardial/endocardial ablation for persistent and longstanding persistent atrial fibrillation. Methods : Between 2017 and 2018, ten patients with persistent and longstanding persistent atrial fibrillation underwent totally thoracoscopic radiofrequency ablation procedure with pulmonary vein isolation, box lesion and left atrial appendage exclusion. They subsequently underwent endocardial mapping with the Rhythmia system and catheter ablation three months later. Any gaps from epicardial ablation were re-ablated. All patients were prospectively followed up. Result : All patients were male and the mean age was 59.3 +/- 6.8 years. 30% of patients had persistent AF and 70% long standing persistent AF. Mean duration of AF preoperatively was 33 +/- 20.5 months. Mean left atrial volume was 51.5 +/- 9.8 mL/m2 Median duration of follow up was 321 days and in this period there were no deaths, conversion to median sternotomy, systemic thromboembolic events or pacemaker implantation. One patient required admission for management of a post-operative left sided pleural effusion. All patients have remained in sinus rhythm with two patients successfully weaned off oral anticoagulants and anti-arrhythmic drugs. One patient had recurrence of atrial fibrillation due to thyrotoxicosis. One patient required repeat endocardial ablation for mitral annular atrial flutter. Conclusion : Sequential hybrid ablation for longstanding persistent AF may be a safe and effective procedure for persistent and longstanding persistent AF in select patients.
