What works in behavioural recognition? A systematic review
No full textOver the last few decades, a growing evidence base for investigative interviewing techniques has informed practitioners and policy-makers worldwide and promoted ethical information elicitation. Many of these techniques rely on elements of behavioural recognition (i.e., our ability to accurately interpret a behavioural or emotional response) to improve communication and cooperation. The current systematic review examined existing literature on ‘what works’ in behavioural recognition across multiple disciplines to address the following question: can we accurately interpret the dynamic behaviour of others? A total of 55 research articles were evaluated, discovering mixed findings across multiple areas. Demographics, individual differences (e.g., emotional intelligence), interview parameters (e.g., contextual knowledge and motivation), interview strategies (e.g., cue detection and thought strategies), and interviewee presentation were all important areas of consideration. However, most importantly, the findings suggests that behavioural recognition is a trainable skill, highlighting the need for further empirical research to be conducted in this area
Interactive Machine Learning: Strategies for live performance using Electromyography
No full textWe present use of the electromyogram (EMG) for sensing musical gesture and discuss interactive machine learning for designing complex muscle-music inter- actions. We propose a signal flow for musical interaction with body movement sensed by EMG and other sensing modalities, feature extraction, and interactive machine learning that result in the manipulation of sound synthesis parame- ters. We discuss ways to capture the EMG for musical use including electrode placement and the use of multiple EMG channels. Techniques for extracting meaningful data and features from electromyographic signals are discussed. We present a composite feature, a multi-channel EMG vector sum. Signal pro- cessing and machine learning are demonstrated. We frame classification and regression as cases of recognising and mapping. We finish by providing a series of resources for musicians wishing to work with the techniques presented here. These tools are free and open source, and can be implemented easily in new applications, projects or products

Rebels without a cause: Collective narcissism and political contrarianism
Full text linkIn this paper, we examine the relationship between collective and individual forms of narcissism and two contrarian political orientations that are oppositional and purposefully destructive—need for chaos and anti-establishment orientation. In three studies (total N = 4144), we demonstrate that (1) national collective narcissism independently predicts higher need for chaos and anti-establishment orientation, (2) non-narcissistic ingroup satisfaction independently predicts lower levels of both contrarian orientations, (3) grandiose narcissism independently predicts higher need for chaos but not anti-establishment orientation, and (4) vulnerable narcissism independently predicts higher levels of both outcomes. We provide evidence for these relationships in cross-sectional regression analyses and in panel analyses that examine within-person construct changes from before to after the 2023 Polish election and better account for time-invariant confounders. Together, these findings suggest contrarian orientations may reflect a (frustrated) narcissistic demand to be recognized as better than others, both collectively and individually
The Art of Planetary Rewilding
No full textSince Sakiya was established in 2016, on a hillside near the Palestinian village of Qiniya that had been quietly rewilding itself since the beginning of the Israeli occupation in 1967, this art/science/agriculture residency, progressive academy, and farm has generated a compelling set of propositions for what it might mean to expand the meaning of “rewild.” Working with local artisans, farmers, and villagers as well as international artists, architects, writers, and students, the cultivation of knowledge at Sakiya involves processes of co-production generated not only through interdisciplinary collaborations between art, science, and technology but also, crucially, through attention to the land and sensitivity to its indigenous more-than-human lifeways. This process, in turn, addresses the climate crisis from the perspective of those most acutely affected by it
"Composer by Necessity": the Theatrical Imperative Behind the Impact, Legacy and Cultural Politics of Deborah Cheetham Fraillon's Pecan Summer (2010)
No full textDeborah Cheetham Fraillon’s Pecan Summer (2010) is an enduring work telling a story based on the 1939 walk-off by residents and workers of the Cummeragunja Station in Yorta Yorta Country. The walk-off was a pivotal moment in the history of Indigenous protest in Australia and an act of necessity: for Indigenous Australian self-determination and for survival. This chapter will examine this “imperative” in the creation of innovative and socially engaged works, the “imperative” meaning that they are story-driven and yet connected to historical truths, whereas so often the canonical power structures that feed genres like opera are wedded to colonial matrices of gender, race, language and geography. In my interview with Deborah Cheetham Fraillon in 2009, she observed that “this story had to be written”. Moreover, in her Peggy Glanville-Hicks Address of 2019, the composer-singer referred to herself as a “composer by necessity”
Martingale Projections and Quantum Decoherence
Full text linkWe introduce so-called super/sub-martingale projections as a family of endomorphisms defined on unions of Polish spaces. Such projections allow us to identify martingales as collections of transformations that relate path-valued random variables to each other under conditional expectations. In this sense, super/sub-martingale projections are random functionals that (i) are boundedness preserving and (ii) satisfy a conditional expectation criterion similar to that of the classical martingale theory. As an application to the theory of open quantum systems, we prove (a) that any system-environment interaction that manifests a supermartingale projection on the density matrix gives rise to decoherence, and (b) that any system-environment interaction that manifests a submartingale projection gives rise an increase in Shannon-Wiener information. It follows (c) that martingale projections in an open quantum system give rise both to quantum decoherence and to information gain
Dyadic synchrony in deaf mothers and hearing infants
Full text linkThere is mounting evidence that maternal sensitivity contributes to optimal child development, but little is known about dyads including deaf mothers and their hearing infants. Deaf adults experience a range of adversities in their role as a parent, and it is unclear how these experiences influence early interactions with their child. Videos of 28 deaf mothers playing with their four-to-eight-month-old hearing infants were coded using the CARE-Index. Dyadic synchrony of most dyads were found to be sensitive or adequate. However, 21% of dyads were likely to benefit from education and/or intervention to increase sensitive interactions. Compared to the rest of the dyads, they displayed lower levels of maternal sensitivity and infant cooperativeness, as well as higher levels of maternal unresponsiveness and infant passivity. Results were influenced by socioeconomic status and potentially by vocal and social touch behaviour. Methodological, theoretical and clinical considerations are offered for professionals working with deaf mothers and their hearing infants
