The language and cultural priorities in Australian Indigenous education have been priority areas since the inaugural national Indigenous education policy was launched in 1989. For over thirty years, ...these priorities have sat awkwardly in the largely non-Indigenous teaching profession and classroom teachers continue to struggle with how to embed these priorities into the education process, despite the efforts of Australian Curriculum, Assessment and Reporting Authority and their elaborations for application at curriculum and practice levels. In this article, I suggest that these language and cultural priorities are at cross-purposes with education priorities, and neither have helped to curb the demise of our Indigenous languages nor improved Indigenous students’ educational outcomes.

Multiscale gyrokinetic turbulence simulations with the real ion-to-electron mass ratio and β value are realized for the first time, where the β value is given by the ratio of plasma pressure to ...magnetic pressure and characterizes electromagnetic effects on microinstabilities. Numerical analysis at both the electron scale and the ion scale is used to reveal the mechanism of their cross-scale interactions. Even with the real-mass scale separation, ion-scale turbulence eliminates electron-scale streamers and dominates heat transport, not only of ions but also of electrons. Suppression of electron-scale turbulence by ion-scale eddies, rather than by long-wavelength zonal flows, is also demonstrated by means of direct measurement of nonlinear mode-to-mode coupling. When the ion-scale modes are stabilized by finite-β effects, the contribution of the electron-scale dynamics to the turbulent transport becomes non-negligible and turns out to enhance ion-scale turbulent transport. Damping of the ion-scale zonal flows by electron-scale turbulence is responsible for the enhancement of ion-scale transport.

If there is a research field that could benefit from some re-imagining, then it is Indigenous education. We only have to look at Indigenous schooling and higher education statistics over time to know ...that progress is slow, and in
places stationary or going backwards on some measures. While the foundations for Indigenous student success in higher education should be laid during the schooling years, continuing rates of failure in that sector mean the large majority
of Indigenous students still arrive at university under-prepared for academic learning demands and therefore require support to succeed. In both sectors Indigenous educational research needs a greater focus on evaluating over the long-
term, the effectiveness of strategies for improving Indigenous students' learning outcomes, as well as a greater willingness to interrogate some of the assumptions on which our strategies and programmes are based. This paper was first
presented as the 2021 Radford Lecture and focuses on the way student support is provided to Indigenous students during their pathway and undergraduate years. It describes a journey I have been on over the last decade and a half with
Indigenous student support staff, research colleagues, and other significant players in two universities where I have initiated a reform process. Author abstract

Abstract
A novel nonlinear functional relation of turbulence potential intensity, zonal flow potential intensity, and ion thermal diffusivity that accurately reproduces nonlinear gyrokinetic ...simulations of toroidal ion temperature gradient (ITG) driven turbulence is proposed. Applying mathematical optimization techniques to find extremal solutions in high-dimensional parameter space, the optimal regression parameters in the functional form are determined to be valid for both near- and far-marginal regime of the ITG stability including the Dimits-shift. Then, the regression error of ∼5% is accomplished. In addition, it is clarified that the intensity ratio of the zonal flow and turbulence potential intensity is a crucial factor to determine the reproduction accuracy.

For a while now I have been researching and writing about Australian Indigenous education issues. Like you all, I have seen much good work and learnt much from what is going on across the country and ...internationally to improve outcomes for Indigenous learners in formal education processes. And still we go on with the struggle and with the limitations that Western sciences and practices place on us in the process. This paper draws together theoretical propositions from the work we have been progressing for the higher education sector over the past decade and to point to some foundational principles that can help establish some early beginnings with Indigenous education as a discipline in the higher education sector.
The transition between isotope-mixing and nonmixing states in hydrogen-deuterium mixture plasmas is observed in the isotope (hydrogen and deuterium) mixture plasma in the Large Helical Device. In the ...nonmixing state, the isotope density ratio profile is nonuniform when the beam fueling isotope species differs from the recycling isotope species and the profile varies significantly depending on the ratio of the recycling isotope species, although the electron density profile shape is unchanged. The fast transition from nonmixing state to isotope-mixing state (nearly uniform profile of isotope ion density ratio) is observed associated with the change of electron density profile from peaked to hollow profile by the pellet injection near the plasma periphery. The transition from nonmixing to isotope-mixing state strongly correlates with the increase of turbulence measurements and the transition of turbulence state from TEM to ion temperature gradient is predicted by gyrokinetic simulation.

Nesfatin-1 is a novel satiety molecule in the hypothalamus and is also present in peripheral tissues. Here we sought to identify the active segment of nesfatin-1 and to determine the mechanisms of ...its action after peripheral administration in mice. Intraperitoneal injection of nesfatin-1 suppressed food intake in a dose-dependent manner. Nesfatin-1 has three distinct segments; we tested the effect of each segment on food intake. Injection of the midsegment decreased food intake under leptin-resistant conditions such as db/db mice and mice fed a high-fat diet. After injection of the midsegment, expression of c-Fos was significantly activated in the brainstem nucleus tractus solitarius (NTS) but not in the hypothalamic arcuate nucleus; the nicotinic cholinergic pathway to the NTS contributed to midsegment-induced anorexia. Midsegment injection significantly increased expression of proopiomelanocortin and cocaine- and amphetamine-regulated transcript genes in the NTS but not in the arcuate nucleus. Investigation of mutant midsegments demonstrated that a region with amino acid sequence similarity to the active site of agouti-related peptide was indispensable for anorexigenic induction. Our findings indicate that the midsegment of nesfatin-1 causes anorexia, possibly by activating POMC and CART neurons in the NTS via a leptin-independent mechanism after peripheral stimulation.
Peripherally administered nesfatin-1 and its mid-segment suppress food intake in mice. The nicotinic cholinergic pathway to the nucleus tractus solitarius contributes to the anorexigenic action of the mid-segment.
