Constructing quality childcare: Perspectives of quality and their connection to Belonging, Being and Becoming
Discourse on quality, within the context of childcare, has moved beyond the level of licensing to consider children’s right to belong. Within Western Australia (WA), there has been a paradigm shift as international research literature on quality childcare has advocated the long- term benefits for individuals and the community when children experience high quality early education and care. This paradigm shift has resulted in new legislation in WA that articulates the components of quality across childcare, as well as the criteria on which centres are assessed. This paper reports the findings of an investigation into the constructs of quality from two stakeholder groups; parents and educators. Findings from this study indicated that, when it comes to quality, what matters most to both parents and educators are the types of interactions children have with others and their environment; the ways in which children’s needs are met; and children’s experiences for development and learning. These findings align with the themes of the nationally mandated early years’ document – the Early Years Learning Framework (Department of Education, Employment and Workplace Relations [DEEWR], 2009) Belonging, Being and Becoming
Latin Square Thue-Morse Sequences are Overlap-Free
We define a morphism based upon a Latin square that generalizes the
Thue-Morse morphism. We prove that fixed points of this morphism are
overlap-free sequences generalizing results of Allouche - Shallit and Frid.Comment: 5 pages, 1 figur
The Navier-Stokes regularity problem
There is currently no proof guaranteeing that, given a smooth initial condition, the three-dimensional Navier–Stokes equations have a unique solution that exists for all positive times. This paper reviews the key rigorous results concerning the existence and uniqueness of solutions for this model. In particular, the link between the regularity of solutions and their uniqueness is highlighted
Well-posedness for the diffusive 3D Burgers equations with initial data in
In this note we discuss the diffusive, vector-valued Burgers equations in a
three-dimensional domain with periodic boundary conditions. We prove that given
initial data in  these equations admit a unique global solution that
becomes classical immediately after the initial time. To prove local existence,
we follow as closely as possible an argument giving local existence for the
Navier--Stokes equations. The existence of global classical solutions is then a
consequence of the maximum principle for the Burgers equations due to Kiselev
and Ladyzhenskaya (1957).
  In several places we encounter difficulties that are not present in the
corresponding analysis of the Navier--Stokes equations. These are essentially
due to the absence of any of the cancellations afforded by incompressibility,
and the lack of conservation of mass. Indeed, standard means of obtaining
estimates in  fail and we are forced to start with more regular data.
Furthermore, we must control the total momentum and carefully check how it
impacts on various standard estimates.Comment: 15 pages, to appear in "Recent Progress in the Theory of the Euler

Representation theory of C-algebras for a higher order class of spheres and tori
We construct C-algebras for a class of surfaces that are inverse images of
certain polynomials of arbitrary degree. By using the directed graph associated
to a matrix, the representation theory can be understood in terms of ``loop''
and ``string'' representations, which are closely related to the dynamics of an
iterated map in the plane. As a particular class of algebras we introduce the
``Henon algebras'', for which the dynamical map is a generalized Henon map, and
give an example where irreducible representations of all dimensions exist.Comment: 14 page
