This paper analyzes the determinants of life satisfaction in a pooled data set of representative individual survey data from seven East European countries collected during the early phase of economic and political transformation using ordered logit models. Those core sociodemographic and economic variables known to be relevant from studies on the US and West European countries (u-shaped age eff...

This thesis explores the relationship between voter income and political ideology preference at the regional and state level. Traditional theories of voter preference contend that richer Americans tend to favor more conservative policy agendas in an effort to minimize income redistribution. The existing empirical literature supports this claim at the national level by finding a significant posi...

Let A, B, be finite subsets of an abelian group, and let G ⊂ A × B be such that #A, #B, #{a + b : (a, b) ∈ G} ≤ N. We consider the question of estimating the quantity #{a − b : (a, b) ∈ G}. In [2] Bourgain obtained the bound of N 2− 1 13 , and applied this to the Kakeya conjecture. We improve Bourgain's estimate to N

a f(x, y) dy, it is often important to know when F is differentiable and when F (x) = ∫ b a f1(x, y) dy. A sufficient condition for differentiating under the integral sign is that ∫ b a f1(x, y) dy converges uniformly; see [6, p. 260]. When we have absolute convergence, the condition |f1(x, y)| ≤ g(y) with ∫ b a g(y) dy < ∞ suffices (Weierstrass M-test and Lebesgue Dominated Convergence). If we...

We calculate the B-model on the mirror pair of X2N−2(2, 2, · · · , 2, 1, 1) , which is an (N − 2)-dimensional Calabi-Yau manifold and has two marginal operators i.e. h(X2N−2(2, 2, · · · , 2, 1, 1)) = 2. In [1] we have discussed about mirror symmetry on XN (1, 1, · · · , 1) and its mirror pair. However, XN (1, 1, · · · , 1) had only one moduli. In this paper we extend its methods to the case wit...

Let M and N be a compact differentiable manifolds of dimension d and d + 1 respectively. Given a compact interval I ⊂ R, we suppose that we have a (fixed) embedding I ×M ⊂ N . See figure 1. Let N denote the complement of {0} ×M . Let h be a Riemannian metric on M , and let ρ be a positive function on R that is positively homogeneous of degree 1 and smooth away from (0, 0). Given (a, b) ∈ R, we ...

It is known that if (A,A∗) is a Leonard pair, then the linear transformations A, A∗ satisfy the Askey-Wilson relations A 2 A ∗ − βAA ∗ A + A∗A2 − γ (AA∗+A∗A) − ̺A∗ = γ∗A2 + ωA + η I, A ∗2 A− βA ∗ AA ∗+ AA∗2− γ∗(A∗A+AA∗) − ̺∗A = γA∗2+ ωA∗+ η∗I, for some scalars β, γ, γ∗, ̺, ̺∗, ω, η, η∗. The problem of this paper is the following: given a pair of Askey-Wilson relations as above, how many Leonard pai...

A transitive (infinite) permutation group which has m orbits on ordered pairs of distinct points has at least mn−1 orbits on ordered n-tuples. This is best possible, and groups attaining the bound can be characterised.

We report results from a search for production of a neutral Higgs boson in association with a b quark. We look for Higgs decays to tau pairs with one tau subsequently decaying to a muon and the other to hadrons. The data come from 2.7 fb−1 of pp collisions recorded by the D0 detector at √ s = 1.96 TeV. The data are found to be consistent with background predictions. The result is used to exclud...

For a nonempty nite set V let 3 V be the set of all the ordered pairs of disjoint subsets of
