Research Report Heart Strings and Purse Strings Carryover Effects of Emotions on Economic Decisions
We examined the impact of specific emotions on the endowment effect, the tendency for selling prices to exceed buying or “choice” prices for the same object. As predicted by appraisaltendency theory, disgust induced by a prior, irrelevant situation carried over to normatively unrelated economic decisions, reducing selling and choice prices and eliminating the endowment effect. Sadness also carr...

متن کاملCrawling Cells Can Close Wounds without Purse Strings or Signaling
When a gash or gouge is made in a confluent layer of epithelial cells, the cells move to fill in the "wound." In some cases, such as in wounded embryonic chick wing buds, the movement of the cells is driven by cortical actin contraction (i.e., a purse string mechanism). In adult tissue, though, cells apparently crawl to close wounds. At the single cell level, this crawling is driven by the dyna...
متن کاملNonlocal Particles as Strings
We find nonlocal particle theories with two dimensional conformal symmetry, including examples equivalent to the bosonic open string and closed string. This work provides a new approach to construct solvable consistent backgrounds in string theory.
متن کاملSchwinger pair creation of particles and strings
I shortly review the worldline instanton method for calculating Schwinger pair production rates in (i) one-loop QED (ii) multiloop QED and (iii) one-loop open string theory. 1. History Already in 1931 F. Sauter [1] realized that Dirac’s theory of the electron predicts that an electric field of sufficient strength and extent can induce spontaneous creation of electron – positron pairs from the v...
