A Trackable Model of Reciprocity and Fairness.
We introduced a parametric model of other-regarding preferences in which my emotional state determines the marginal rate of substitution between my own and other' payoffs, and thus my subsequent choices. In turn, my emotional state responds to relative status and to the kindness or unkindness of others' choices. Structural estimations of this model with six existing data sets demonstrate that other-regarding preferences depend on status, reciprocity, and perceived property rights.RECIPROCITY ; MARGINAL RATE OF SUBSTITUTION ; PAYOFFS
Wild Walls: Domus Linea Insecare as Dreamt by Scogin Elam and Gray Architects
Like the other projects in The Architect\u27s Dream exhibition, Scogin Elam Bray\u27s Domus Linea Insecare represents a critical practice: it puts the commonplace dream-house into abeyance; it develops dream house as a topic, not an object; it exercises this topic in respect to the changing status of domestic experience; it carries the spatial and material experience of architecture into its inhabitant; it questions architectural thinking as a measure of the changing constitution of the postmodern subject (the self, the T); it examines the way the subject of the house reflects the question of being and embodiment
Modification of turbulent transport with continuous variation of flow shear in the Large Plasma Device
Continuous control over azimuthal flow and shear in the edge of the Large
Plasma Device (LAPD) has been achieved using a biasable limiter which has
allowed a careful study of the effect of flow shear on pressure-gradient-driven
turbulence and transport in LAPD. LAPD rotates spontaneously in the ion
diamagnetic direction (IDD); positive limiter bias first reduces, then
minimizes (producing a near-zero shear state), and finally reverses the flow
into the electron diamagnetic direction (EDD). Degradation of particle
confinement is observed in the minimum shearing state and reduction in
turbulent particle flux is observed with increasing shearing in both flow
directions. Near-complete suppression of turbulent particle flux is observed
for shearing rates comparable to the turbulent autocorrelation rate measured in
the minimum shear state. Turbulent flux suppression is dominated by amplitude
reduction in low-frequency (kHz) density fluctuations. An increase in
fluctuations for the highest shearing states is observed with the emergence of
a coherent mode which does not lead to net particle transport. The variations
of density fluctuations are fit well with power-laws and compare favorably to
simple models of shear suppression of transport.Comment: 10 pages, 5 figures; Submitted to Phys. Rev. Let

Necrotic tumor growth: an analytic approach
The present paper deals with a free boundary problem modeling the growth
process of necrotic multi-layer tumors. We prove the existence of flat
stationary solutions and determine the linearization of our model at such an
equilibrium. Finally, we compute the solutions of the stationary linearized
problem and comment on bifurcation.Comment: 14 pages, 3 figure
