In this study I present experimental evidence of a novel channel yielding inequality persistence. In an initial experiment, results suggest that individuals respond to salient inequality by adjusting their performance beliefs to justify the inequality. Subsequent experiments reveal: i) that it is beliefs about relative ability—an ostensibly stable trait— rather than effort provision that respon...

Economists typically object to preference-based explanations of human behavior; differences in preferences “explain everything and therefore nothing”. But this argument is only correct assuming that no empirical evidence exists to discipline preference-based explanations. In fact, over the past decade, personality psychologists have produced a robust collection of stylized facts about human pre...

We study a discrete time model of the growth of two species of plankton with competitive and allelopathic effects on each other N1(k + 1) = N1(k)exp{r1(k)− a11(k)N1(k)− a12(k)N2(k) − b1(k)N1(k)N2(k)}, N2(k + 1) = N2(k)exp{r2(k) − a21(k)N1(k) − a22(k) N2(k)− b2(k)N1(k)N2(k)}. A set of sufficient conditions is obtained for the existence of multiple positive periodic solutions for this model. The ...

Let T be an operator-weighted shift whose weights are 2-by-2 matrices. We say that, given > 0, T is in the -canonical form if each weight is an upper triangular matrix (aij), with 0 ≤ a11, a22 ≤ 1 and a12 6= 0 implies a11, a22 < . We generalize this concept to operator-weighted shifts whose weights are n-by-n matrices and we show that every polynomially bounded weighted shift, whose weights are...

We produce several families of solutions for two-component nonlinear Schrödinger/GrossPitaevskii equations. These include domain walls and the first example of an antidark or gray soliton in one component, bound to a bright or dark soliton in the other. Most of these solutions are linearly stable in their entire domain of existence. Some of them are relevant to nonlinear optics, and all to Bose...

Nuclear power plants that produce sustainable energy are the most striking examples of generating carbon-free energy. However, nuclear demand safe management waste. The radiation tests materials, which used in successful waste plants, must be carried out. In this study, interaction parameters were examined International simple glasses (ISG) with superior properties, management. gamma shielding ...
