Lyapunov exponents for infinite dimensional dynamical systems

Classically it was held that solutions to deterministic partial differential equations (i.e., ones with smooth coefficients and boundary data) could become random only through one mechanism, namely by the activation of more and more of the infinite number of degrees of freedom that are available to such a system. It is only recently that researchers have come to suspect that many infinite dimensional nonlinear systems may in fact possess finite dimensional chaotic attractors. Lyapunov exponents provide a tool for probing the nature of these attractors. This paper examines how these exponents might be measured for infinite dimensional systems

Learning to Put Everyday Creativity, Semiotics and Critical Visual Literacy Using Inquiry Graphics (IG) Visual Analysis to Work in Social Care

This article argues that despite CORU’s recognition of Creative Arts as integral to Social Care Practice, there are ‘pedagogical, theoretical and practice gaps’, which might be addressed through a ‘process orientated novel creative pedagogy’ (PONCP) introduced in this paper. The PONCP is built on two tenets, firstly that creative expression is not just for professional artists – everyone is capable of creative expression, though cultural messages make us believe otherwise, and secondly engaging in creative practice is therapeutic in varying degrees from passing time productively to psychoanalytic engagement. A curriculum is proposed comprising: edusemiotics (the interpretation and creation of meaning), multimodality (the use of different modes / tools of/for expression) and Inquiry Graphics (a tool for critical analysis of photographs) (Lacković, 2010, 2020). Through this PONCP the author hopes to establish a terrain for future research and elaboration, and to develop creative, reflective and analytic capabilities for effective, high-quality practice with service users. The PONCP aims to support social care creative work by promoting everyday creativity and imagination as an affirming expressive and adaptive ability through understanding how ‘signs’ construct meaning and therefore learning. By critically reading and analysing the visual world through ‘signs’, socially constructed ideologies and accepted visual meaning can be challenged revealing hidden truths. Overall this may serve to enhance professional practice as well as professional critical appraisal in keeping with the CORU Standards of Proficiency

What to do with all these Bayes factors: How to make Bayesian reports in deception research more informative

Bayes factors quantify the evidence in support of the null (absence of an effect) or the alternative hypothesis (presence of an effect). Based on commonly used cut-offs, Bayes factors between 1/3 and 3 are interpreted as evidentially weak, and one typically concludes there is an absence of evidence. In this commentary on Warmelink, Subramanian, Tkacheva, and McLatchie (Legal Criminol Psychol 24, 2019, 258), we discuss how a Bayesian report can be made more informative. Firstly, this implies a departure from the labels provided by commonly used cut-offs when reporting Bayes factors. Instead, we encourage researchers to report the value of the Bayes factors, or to

Yeatsian Shades In Ó Direáin and Macgill-Eain

Michael Hartnett’s grandiloquent valediction ‘A Farewell to English’, first delivered from the stage of the Peacock Theatre in Dublin in 1974, announced the thirty-three year-old poet’s decision to cease publishing in his native English, the language in which he had already earned a considerable reputation, in order to devote himself henceforth to poetry in Irish

Interview with Ailbhe Ní Bhriain

Ailbhe Ní Bhriain is an Irish artist working with film, photography and installation. Using collage and computer-generated imagery (CGI), she transforms familiar images and locations into worlds of dream-like theatricality, drawing the viewer into an altered experience of time and place. Her work has been exhibited widely both nationally and internationally and regularly involves collaboration with musicians and composers. She holds a PhD by practice in Fine Art, Kingston University, UK (2008..
