Hoea a mai tĆu waka â Claiming spaces for MÄori tamariki and rangatahi in cognitive behaviour therapy
Cognitive Behaviour Therapy (CBT) has been shown to be an effective therapeutic intervention for a variety of psychological difficulties for children and youth (Barrett, Healey-Farrell, March, 2004; Stulemeijer, de Jong, Fiselier, Hoogveld, Bleijenberg, 2005; Butler, Chapman, Forman & Beck, 2006). However there is very little literature on its utility with indigenous children or youth, most of the literature has tended to look at âminorityâ populations and has focused on psychological outcomes (Weersing & Weisz, 2002; McNeil, Capage, Bennett, 2002)
Resolution of the time dependent Pn equations by a Godunov type scheme having the diffusion limit. Part 1 : The case of the time dependent P1 equations
We consider the P1 model to approximate the time dependent transport equation in one dimension of space. In a diffusive regime, the solution of this system is solution of a diffusion equation. We are looking for a numerical scheme having the diffusion limit property: in a diffusive regime, it has to give the solution of the limiting diffusion equation on a mesh at the diffusion scale. The numerical scheme is an extension of the Godunov type scheme proposed by L.Gosse to solve the P1 model without absorption term. It requires the computation of the solution of the steady P1 equations. Using formal expansions with respect to a small parameter representing the inverse of the number of mean free path in each cell, the resulting scheme is proved to have the diffusion limit. In order to avoid the CFL constraint on the time step, we give an implicit version of the scheme which preserves the positiveness of the zeroth moment
Quantum dynamics and breakdown of classical realism in nonlinear oscillators
The dynamics of a quantum nonlinear oscillator is studied in terms of its
quasi-flow, a dynamical mapping of the classical phase plane that represents
the time-evolution of the quantum observables. Explicit expressions are derived
for the deformation of the classical flow by the quantum nonlinearity in the
semiclassical limit. The breakdown of the classical trajectories under the
quantum nonlinear dynamics is quantified by the mismatch of the quasi-flow
carried by different observables. It is shown that the failure of classical
realism can give rise to a dynamical violation of Bell's inequalities.Comment: RevTeX 4 pages, no figure
The migration of adult female blue crabs, Callinectes sapidus Rathbun, in Chincoteague Bay and adjacent waters
A total of 392 adult female blue crabs were tagged at four different points in the Chincoteague Bay area from 31 July to 7 September 1953. Over a period including June 1954, about 25% were recaptured, mostly to the south of the release points. Only three had moved northward, and only two were recaptured outside the area; one in Delaware Bay and one at Oyster, Virginia. Factors that may influence their movements and some ecological considerations are discussed
Weapons to widgets: Organic systems and public policy for tech transfer
Large cuts in defense spending cause serious repercussions throughout the American economy. One means to counter the negative effects of defense reductions is to redirect federal dollars to temporarily prop up defense industries and, over the longer-term, stimulate growth of new nondefense industries. The creation of non-defense products and industries by channeling ideas from public laboratories into the private sector manufacturing facilities, known as technology transfer, is being undertaken in a massive program that has high visibility, large amounts of money, and broad federal agency involvement. How effectively federal money can be directed toward stimulating the creation of non-defense products will define the strength of the economy, (i.e., tax base, employment level, trade balance, capital investments, etc.), over the next decade. Key functions of the tech transfer process are technology and market assessment, capital formation, manufacturing feasibility, sales and distribution, and business organization creation. Those, however, are not functions typically associated with the federal government. Is the government prepared to provide leadership in those areas? This paper suggests organic systems theory as a means to structure the public sector's actions to provide leadership in functional areas normally outside their scope of expertise. By applying new ideas in organization theory, can we design government action to efficiently and effectively transfer technologies
