Dispersion enhancement and damping by buoyancy driven flows in 2D networks of capillaries
The influence of a small relative density difference on the displacement of
two miscible liquids is studied experimentally in transparent 2D networks of
micro channels. Both stable displacements in which the denser fluid enters at
the bottom of the cell and displaces the lighter one and unstable displacements
in which the lighter fluid is injected at the bottom and displaces the denser
one are realized. Except at the lowest mean flow velocity U, the average
of the relative concentration satisfies a convection-dispersion
equation. The dispersion coefficient is studied as function of the relative
magnitude of fluid velocity and of the velocity of buoyancy driven fluid
motion. A model is suggested and its applicability to previous results obtained
in 3D media is discussed

Language Breathes Life -Barngarla Community Perspectives on the Wellbeing Impacts of Reclaiming a Dormant Australian Aboriginal Language
Traditional languages are a key element of Indigenous peoples\u27 identity, cultural expression, autonomy, spiritual and intellectual sovereignty, and wellbeing. While the links between Indigenous language loss and poor mental health have been demonstrated in several settings, little research has sought to identify the potential psychological benefits that may derive from language reclamation. The revival of the Barngarla language on the Eyre Peninsula, South Australia, offers a unique opportunity to examine whether improvements in mental health and social and emotional wellbeing can occur during and following the language reclamation process. This paper presents findings from 16 semi-structured interviews conducted with Barngarla community members describing their own experienced or observed mental health and wellbeing impacts of language reclamation activities. Aligning with a social and emotional wellbeing framework from an Aboriginal and Torres Strait Islander perspective, key themes included connection to spirituality and ancestors; connection to Country; connection to culture; connection to community; connection to family and kinship; connection to mind and emotions; and impacts upon identity and cultural pride at an individual level. These themes will form the foundation of assessment of the impacts of language reclamation in future stages of the project

The Impossibility of a Perfectly Competitive Labor Market
Using the institutional theory of transaction cost, I demonstrate that the assumptions of the competitive labor market model are internally contradictory and lead to the conclusion that on purely theoretical grounds a perfectly competitive labor market is a logical impossibility. By extension, the familiar diagram of wage determination by supply and demand is also a logical impossibility and the neoclassical labor demand curve is not a well-defined construct. The reason is that the perfectly competitive market model presumes zero transaction cost and with zero transaction cost all labor is hired as independent contractors, implying multi-person firms, the employment relationship, and labor market disappear. With positive transaction cost, on the other hand, employment contracts are incomplete and the labor supply curve to the firm is upward sloping, again causing the labor demand curve to be ill-defined. As a result, theory suggests that wage rates are always and everywhere an amalgam of an administered and bargained price. Working Paper 06-0
