Sowing the Wind and Reaping the Whirlwind? The Effect of Wind Turbines on Residential Well-Being
We investigate the effect of the physical presence of wind turbines on residential wellbeing in Germany, using panel data from the German Socio-Economic Panel (SOEP) and a unique novel panel data set on more than 20,000 wind turbines for the time period between 2000 and 2012. Using a Geographical Information System (GIS), we calculate the proximity between households and the nearest wind turbin...
متن کاملSowing Patriotism, But Reaping Nationalism? Consequences of Exposure to the American Flag
The American flag is a frequently displayed national symbol in the United States. Given its high visibility and importance, the present research examines the consequences of exposure to the flag on Americans’ sense of national attachment. We hypothesized that the flag would increase patriotism, defined as love and commitment to one’s country, and nationalism, defined as a sense of superiority o...
متن کاملAround splitting and reaping
We prove several results on some cardinal invariants of the continuum which are closely related to either the splitting number s or its dual, the reaping number r.
متن کاملReaping Numbers of Boolean Algebras
A subsetA of a Boolean algebra B is said to be (n,m)reaped if there is a partition of unity P ⊂ B of size n such that |{b ∈ P : b∧a 6= ∅}| ≥ m for all a ∈ A. The reaping number rn,m(B) of a Boolean algebra B is the minimum cardinality of a set A ⊂ B\ {0} such which cannot be (n,m)-reaped. It is shown that, for each n ∈ ω, there is a Boolean algebra B such that rn+1,2(B) 6= rn,2(B). Also, {rn,m(...
متن کاملOn Shattering, Splitting and Reaping Partitions
In this article we investigate the dual-shattering cardinal H, the dualsplitting cardinal S and the dual-reaping cardinal R, which are dualizations of the well-known cardinals h (the shattering cardinal, also known as the distributivity number of P(ω)/fin), s (the splitting number) and r (the reaping number). Using some properties of the ideal J of nowhere dual-Ramsey sets, which is an ideal ov...
