(Re)imagining entangled sustainability : a human and nonhuman theorisation of belonging to safeguard sustainability’s holism

After years of research and theorisation connected to education for sustainable development, the holistic core of sustainability seems to have disappeared within the frames of the social, environmental and economic pillars. This article suggests a post-humanism inspired understanding of a sense of belonging. Even though the phenomenon of belonging is ascribed to social sustainability, the post-human theoretical toolkit challenges the humanism-based understanding of a sense of belonging as a human-related phenomenon. Using Deleuze and Guattari’s rhizome and affect concepts and Barad’s concept of intra-action, we show the connections between the human and nonhuman elements constituting each other in our world. We conclude with the implications that using post-human language (to understand belonging) may have for policy, Early Childhood Education and care (ECEC) practice and theory

Noncompliant Learning: Diffracting SpaceTimes, Intra-active Ropes, and a Museum's Roping into the City through a Curious Child

In this article, the authors intra-act with Barad's (2007) conceptual toolkit to examine noncomplaint learning of a ropemaking activity at The Norwegian Fisheries Museum in Bergen. Barad's concepts of intra-action and diffraction allow us to perceive the rope as noncompliantly diffracting into the two different SpaceTimes of the 19th and 21st centuries. The former SpaceTime is intra-actively constituted by historical ropemaking craftship and the museum staff, and the latter by the children's approaching the ropemaking through toys and play. In the overlap of the entanglements of the two SpaceTimes, noncompliant and 'new areas of curiosity' (Wertsch 2002, p. 123) unfold and continue the rope's diffraction into the city. By following the intra-active community of Ida and the rope, the authors map entanglements of more-than-human worldings and conclude with a call for more museal diffractions that can (intra-)activate the museum's relational capacities in the ecology of the city

Unfreezing the discursive hegemonies underpinning current versions of “social sustainability” in ECE policies in Anglo–Celtic, Nordic and Continental contexts

Social sustainability is linked to finding new ways of living together and strengthening social capital and participation, as well as to social justice and equity in societies, and it is becoming increasingly important for diverse multicultural societies. In this article, we trace understandings of social sustainability as established in Early Childhood Education (ECE) policy documents by following the chains of meaning connected to sense of belonging, local place and cultural diversity and through ECE collaboration with children’s parents/caregivers. Critical discourse analysis has been applied to trace the chains of meaning attached to these concepts in ECE steering documents in Australia, Croatia, Denmark, Norway, Poland, Serbia, Slovenia, Sweden and the UK (England, Scot-land, Wales and Northern Ireland). Such analysis shows different ways in which the ECE polices indirectly work with social sustainability, as well as create critical distance from the sets of meanings established in each country (by proving a chain of meaning established in the policy documents of another country). In conclusion, we do not advocate in favour of any of the chains of meaning but argue for continual reflection and reflexivity, and we see research to be a particularly significant arena in which to unfreeze the taken for granted and sustainable notion

Nucleophilic catalysis of acylhydrazone equilibration for protein-directed dynamic covalent chemistry

Dynamic covalent chemistry uses reversible chemical reactions to set up an equilibrating network of molecules at thermodynamic equilibrium, which can adjust its composition in response to any agent capable of altering the free energy of the system. When the target is a biological macromolecule, such as a protein, the process corresponds to the protein directing the synthesis of its own best ligand. Here, we demonstrate that reversible acylhydrazone formation is an effective chemistry for biological dynamic combinatorial library formation. In the presence of aniline as a nucleophilic catalyst, dynamic combinatorial libraries equilibrate rapidly at pH 6.2, are fully reversible, and may be switched on or off by means of a change in pH. We have interfaced these hydrazone dynamic combinatorial libraries with two isozymes from the glutathione S-transferase class of enzyme, and observed divergent amplification effects, where each protein selects the best-fitting hydrazone for the hydrophobic region of its active site
