The ecology of hope: Building rainbows in education systems
British Educational Research Journal, EarlyView.Abstract Hope is frequently invoked in education, yet rarely theorised. Where it has been theorised, it has been understood in two largely separate ways: as an individual psychological capacity, in the positive‐psychology tradition and as a critical‐emancipatory stance, in the pedagogy of hope.

The Irreducibility of Emotional Phenomenology [PDF]
Erkenntnis, 2018 AbstractEmotion theory includes attempts to reduce or assimilate emotions to states such as bodily feelings, beliefs-desire combinations, and evaluative judgements. Resistance to such approaches is motivated by the claim that emotions possess asui generisphenomenology.

Hilbert irreducibility above algebraic groups.
, 2010 The paper proves new results on the irreducibility of fibers of a cover of an algebraic group, above a cyclic subgroup. This provides entirely new versions of Hilbert Irreducibility, settling in particular a conjecture of Pisot.

Business Strategy and the Environment, EarlyView.ABSTRACT Corporate sustainability research is rich but fragmented where influential frameworks illuminate important aspects of sustainability dynamics, yet they are often used in parallel rather than connected through a shared explanatory logic of change. This paper addresses that corporate sustainability puzzle through a targeted literature review and

Deterministic irreducibility testing of polynomials over large finite fields [PDF]
, 1987 We present a sequential deterministic polynomial-time algorithm for testing dense multivariate polynomials over a large finite field for irreducibility. All previously known algorithms were of a probabilistic nature.

Chiari I Malformation: Review and Update of Current Treatment Options
Clinical Anatomy, EarlyView.ABSTRACT The pathophysiology of Chiari malformation type I (CM‐I) is complex, involving structural abnormalities at the craniovertebral junction that result in herniation of the cerebellar tonsils through the foramen magnum. In this study, we aim to present and evaluate current treatment options for CM‐I, with a focus on evidence‐based clinical ...

Some sufficient conditions for an amalgamated 3-manifold to be irreducible
Open MathematicsLet M = M 1 ∪F M 2 be an amalgamation of two irreducible 3-manifolds M 1 and M 2 along a compact connected surface F (not necessarily closed). In the paper, we introduce the extended curve complex C̃(F) $\tilde {C}\left(F\right)$ of a compact connected ...

Compact Manifolds With Unbounded Nilpotent Fundamental Groups and Positive Ricci Curvature
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT It follows from the work of Kapovitch and Wilking that a closed manifold with nonnegative Ricci curvature has a uniformly almost nilpotent fundamental group. Leftover questions and conjectures, have asked if in this context the fundamental group is actually uniformly almost abelian. The main goal of this work is to construct examples (Mk9,gk)$(

Quasi-Irreducibility of Nonnegative Biquadratic Tensors
MathematicsWhile the adjacency tensor of a bipartite 2-graph is a nonnegative biquadratic tensor, it is inherently reducible. To address this limitation, we introduce the concept of quasi-irreducibility in this paper.
