Status Quo Effects in Fairness Games: Acts of Commission vs. Acts of Omission

Intent to help or harm is revealed more clearly by acts of commission that overturn the status quo than by acts of omission that uphold it. Both the law and culture make a central distinction between the two types of acts. Acts of commission elicit stronger reciprocal responses than do acts of omission. In this paper we compare reciprocal responses to both types of acts and ask whether behavior of subjects in two experiments is consistent with existing theory. The design of the experiments focuses on the axioms of revealed altruism theory (Cox, Friedman, and Sadiraj, 2008) that make it observationally distinct from other theories, Axiom R (for reciprocity) and Axiom S (for status quo). We find support for this theory in both experiments.

Saliency of Outside Options in the Lost Wallet Game

This paper reports an experiment designed to shed light on an empirical puzzle observed by Dufwenberg and Gneezy (2000) that the size of the foregone outside option by the first mover does not affect the behavior of the second mover in a lost wallet game. Our conjecture was that the original protocol may not have made the size of the forgone outside option salient to second movers. Therefore, we change two features of the Dufwenberg and Gneezy protocol: (i) instead of the strategy method we implement a direct response method (sequential play) for the decision of the second mover; and (ii) we use paper money certificates that are passed between the subjects rather than having subjects write down numbers representing their decisions. We observe that our procedure yields qualitatively the same result as the Dufwenberg and Gneezy experiment, i.e., the second movers do not respond to the change in the outside option of the first movers.Experimental economics; Lost wallet game; Outside option

Growing Grounds Farm & Nursery - Serenity Shade Structure

This project includes the design and construction of a shade structure over the serenity seating area at Growing Grounds Farm & Nursery. Growing Grounds is a part of TransitionsMental Health Association. It is a nonprofit wholesale nursery that provides horticulture, socialization opportunities, paid employment and soft job skills training for adults with severe and persistent mental illness. The shade structure will serve as place where staff and volunteers can gather and sit

Electrochemical oxidation and detection of sodium urate in alkaline media on a copper oxides electrode

Electrochemical behaviour of copper oxides electrode in the presence of sodium urate was investigated. The correlation between the anodic oxidation and the amperometric detection of sodium urate in the alkaline medium on copper oxides electrode was analysed by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) measurements. The intereference from sodium tartrate presence in the aqueous alkaline solution was tested. Copper oxides electrodes can be used successfully for amperometric detection of both sodium urate and mixture of urate and tartrate as a cumulative response, in alkaline media, the target compound did not interfere each other.

Thermal-Hall conductivity and long-lived quasiparticles in CeCoIn5_5

In CeCoIn$_5$, the thermal conductivity $\kappa_{xx}$ and Hall conductivity $\kappa_{xy}$ below $T_c$ display large anomalies below $T_c$. The strong suppression of the anomalies in weak fields implies the existence of long-lived quasiparticles. We also discuss briefly the Wiedemann-Franz ratio and the existence of a strongly field-dependent spin-fluctuation heat current.Comment: 2 pages, 2 figures, proceedings of M2S-HTSC-VIII, Dresden 200

Unusual Higgs or Supersymmetry from Natural Electroweak Symmetry Breaking

This review provides an elementary discussion of electroweak symmetry breaking in the minimal and the next-to-minimal supersymmetric models with the focus on the fine-tuning problem -- the tension between natural electroweak symmetry breaking and the direct search limit on the Higgs boson mass. Two generic solutions of the fine-tuning problem are discussed in detail: models with unusual Higgs decays; and models with unusual pattern of soft supersymmetry breaking parameters.Comment: 23 pages, 6 figures; invited review by MPL
