Intravenous thrombolysis for ischemic stroke after recent direct oral anticoagulant (DOAC) ingestion remains controversial due to hemorrhagic risk, limited rapid testing and inconsistent reversal strategies. We conducted an invite-only, web-based cross-sectional survey of Canadian stroke centers using a structured questionnaire. DOAC level testing was inconsistently available, with 9/13 centers (69%) reporting access but 8/13 centers (61%) reporting turnaround times exceeding 30 minutes. Consequently, 9/13 centers (69%) did not routinely use DOAC levels to guide thrombolysis decisions. Current practice demonstrates substantial variability and uncertainty, highlighting important evidence gaps and the potential role of clinical trials and consensus guideline development.

We present a novel approach to correcting Hα luminosity functions for dust extinction by calibrating against radio-based star formation rates (SFRs), using data from the Evolutionary Map of the Universe (EMU) and Galaxy and Mass Assembly (GAMA) surveys. Accurate dust correction is essential for deriving SFRs from rest-frame UV-optical emission lines, particularly as the James Webb Space Telescope extends such measurements to galaxies at z > 5. While a luminosity dependence of dust obscuration has long been recognised, our method exploits the empirical relationship between obscured (Hα) and unobscured (radio) SFRs to provide a dust correction that can be applied where traditional spectroscopic techniques, e.g. Balmer line based approaches, are unavailable. We apply the SFR based dust correction to 25 published Hα luminosity functions spanning 0 < z < 8, and derive corresponding star formation rate densities (SFRDs). Adopting the locally calibrated Hα–radio relation ends up with an overestimate of the cosmic SFRD by more than two orders of magnitude at z ≳ 1. Motivated by the luminosity dependent relation in the local Universe, we introduce a new model where the luminosity dependence of the dust obscuration decreases with increasing redshift. This approach can reproduce observed SFRDs across cosmic time. These results highlight the potential of a radio-based calibration for dust correction, where a luminosity dependent correction would need to decline in strength with increasing redshift. This implies that the dust content or distribution in galaxies at early epochs differs substantially from that in the local Universe.

In this article, we present an innovative programming and instructional practice to foster the social-emotional competence of twice-exceptional students — those who are gifted and have a learning disability. We review the benefits of bibliotherapy, provide an overview of the structure of a developmental bibliotherapy intervention, and identify potential barriers to implementation before providing a guide for teachers. Gifted students with attention-deficit/hyperactivity disorder (ADHD) may be supported to develop social-emotional wellbeing and competence through developmental bibliotherapy. Due to a gap in the research with this particular population of students, we focused on reviewing research that explored the use of bibliotherapy with gifted students specifically and the wider student population generally. This instructional practice can be utilised by counsellors, teachers, and gifted and talented coordinators to meet the unique needs of this student population in Australian primary schools. A reflection on the implementation of this guide for gifted students is shared from a practitioner’s perspective to conclude the article.

This paper explores the multiple stories and affective traces that wetlands and swamps generate in more-than-human environments. Situated on what was once a swamp, Naarm (Melbourne) provides the setting for the authors’ collective creative inquiry. This work explores more-than-human methodologies of knowledge creation, examines how these approaches impact multispecies justice and investigates how wetlands can serve as transitional, unstaged spaces that challenge and disrupt colonial infrastructures. While drawing back on memories and experiences of wetlands in Southern China and Southeast Europe, the authors incorporate poetic mappings and autoethnographic interviews in exploring the reminisces and encounters living with more-than-human pasts and presents. Following the way of wetlands, the authors seek to foster unexpected ecologies between water, land, species and a multiplicity of ontologies in the abundance of in-between spaces as a generative learning-creation site.

We present computations of individual mode-to-mode energy transfers from direct numerical simulations of homogeneous isotropic turbulence. Unlike previous approaches based on shell-filtered velocity fields, this method distinguishes between the energy exchanged by each pair of modes within a triad. We introduce a potential function based on the energy content of the modes involved, and show that it predicts the distribution of intense energy transfers in the vicinity of the sampling mode considered. By performing simulations with forcing applied at intermediate wavenumbers, we demonstrate that the region of most intense transfers is determined by the spectral location of the energy-containing scales rather than by the local or non-local character of the triad. Direct energy exchanges with the energy-containing range are suppressed by geometric constraints from the divergence-free condition, but persist as residuals when the sampling mode is close to the energy-containing scales. The comparison with an estimator derived from eddy-damped quasi-normal Markovian theory shows good agreement and recovers the forward, scale-local nature of energy transfer consistent with the cascade picture.

The ‘Digital Economy and Society Index’ (DESI) Dashboard for the Digital Decade is a set of indicators created by the European Union in the early 2010s to monitor Member States’ progress in pursuing the EU’s Digital Agenda, as well as many of the goals of the UN’s 2030 Agenda for Sustainability. The figures provided by the Dashboard are perceived by academics, the media and the general public as objective neutral data on the progress of Member States towards digitalisation, and on the promotion of sustainable development. This short contribution unpacks the Dashboard, examining the variables it considers and the methodology it employs, and finds out a very different picture. The Dashboard mainly assesses how easily people can access products and services online. It thus promotes a pro-market digitalisation agenda that excludes any other possible alternative and has little to do (if any) with the idea of sustainability. As is often the case with quantitative measurements of social phenomena, behind its seemingly scientific numerical veil the Dashboard conveys a policy vision that is hardly compatible with the objectives the Dashboard allegedly promotes. The essay thus raises broader questions as to the legitimacy of governing through indicators and as to the role of EU in shaping Member States’ digital future.
