Culture and Psychological Responses to Environmental Shocks
Sidama people occupy a subsistence niche partitioned between traditional enset agropastoralism and transitional maize farming. Enset production is low risk and requires multiple years for cultivation and processing. Maize farming is high risk and high yield, requiring one growing season from planting to harvest. Contrasting enset and maize farming, we examine effects of crop loss and social sho...
متن کاملOn delta-shocks and singular shocks
It is well known that there are “nonclassical” situations where, in contrast to Lax’s and Glimm’s results,systems of conservation laws may admit singular solutions (δ-shocks and singular shocks) such that their components contain delta functions [ASh05], [B94], [DSh03]– [LW02], [S02]– [Sh04], [TZZ94]. The exact structure of such type solutions is given below in (2), (7) and Definition 1. The th...
متن کاملCulture Shocks and Consequences: the connection between the arts and urban economic growth
Is there a relationship between local arts and culture production and local prosperity that is permanent rather than transitory? The answer to this question determines whether arts and culture production generates economic growth or a temporary ‘multiplier’ effect that diminishes over time. We argue that despite the obvious public policy interest in the subject there has been no fully satisfact...

The answer to this question determines whether arts and culture production generates economic growth or a temporary ‘multiplier’ effect that diminishes over time.

متن کاملLocalized shocks
We study products of precursors of spatially local operators, Wxn(tn) . . .Wx1(t1), where Wx(t) = e Wxe iHt. Using chaotic spin-chain numerics and gauge/gravity duality, we show that a single precursor fills a spatial region that grows linearly in t. In a lattice system, products of such operators can be represented using tensor networks. In gauge/gravity duality, they are related to Einstein-R...
