The Politics of Framing the Student Problem: Inquiries Into Australian Civics Education, 2006–2024

Australian Journal of Social Issues, EarlyView.
ABSTRACT Recurring debates about civics, the kinds of history that should, and should not, be taught in school, and ‘standards debates’ about the ‘basics’ typically follow on the heels of recurring moral panics about the ‘declining’ state of ‘our’ education system.

Upper and Lower Solutions Method for Darboux Problem for Fractional Order Implicit Impulsive Partial Hyperbolic Differential Equations [PDF]

, 2010
summary:In this paper we investigate the existence of solutions for the initial value problems (IVP for short), for a class of implicit impulsive hyperbolic differential equations by using the lower and upper solutions method combined with Schauder’s ...

Prediction of First and Recurrent Falls in Parkinson's Disease

Annals of Neurology, EarlyView.
Objective To develop and externally validate prediction models for next‐year falls in Parkinson's disease (PD), and to evaluate the incremental value of imaging and fluid biomarkers. Methods We developed models in Parkinson's Progression Markers Initiative (PPMI) to predict next‐year falls with external validation in University of Pennsylvania (UPenn ...

Interval oscillation criteria for impulsive conformable fractional differential equations

, 2020
In this paper, we derive new interval oscillation criteria for impulsive conformable fractional differential equations having fixed moments of impulse actions. The results are extended to a more general class of nonlinear impulsive conformable fractional

MHD Maxwell Hybrid Nanofluid Transport Featuring Solar Radiation and Thermo‐Diffusive Impacts Over a Permeable Slanted Stretching Sheet

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Hybrid nanofluids have emerged as next‐generation working fluids for advanced engineering application due to their superior heat transport capability in relation to the conventional nanofluids. Motivated by the rising demand for accurate prediction of transport phenomena under realistic operating situations, the present study examines the ...

Resonance phenomena in the second differential order equations with nonlinear impulsive effects

Electronic Journal of Qualitative Theory of Differential Equations
In this paper, we discuss the resonance phenomena in linear and weakly nonlinear impulsive differential equations. Using a topological approach, we obtain the Landesman–Lazer type necessary and sufficient conditions for the existence of periodic ...

Gas‐Phase Residence Time Distribution Characteristics in a Gas–Liquid Stirred Tank With Multiple Impellers

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Residence time distribution (RTD) is a standard tool for characterizing the hydrodynamic performance of stirred tanks. In this work, gas‐phase RTD was experimentally investigated in a gas–liquid stirred tank equipped with six multiple‐impeller configurations using four impeller types (WH, HEDT, CBY, and PDT). The effects of impeller speed, gas
