I study the effects of the heterogeneity of traders’ horizons in a 2-period NREE model where all traders are risk averse. Owing to risk premia, short termism generates multiple equilibria. In particular two distinct patterns arise. Along the “low trading intensity equilibrium,” short termists anticipate a thinner second period market and, owing to risk aversion, scale back their trades. This re...

In this article, an exact levy solution is presented for bending analysis of a functionally graded (FG) annular sector plate. The governing equilibrium equations are obtained based on the classical plate theory. Introducing an analytical method for the first time, the three coupled governing equilibrium equations are replaced by an independent equation in term of transverse deflection. This equ...

The paper derives a general form of the term structure of interest rates. The following assumptions are made: (A.l) The instantaneous (spot) interest rate follows a diffusion process; (A.2) the price of a discount bond depends only on the spot rate over its term; and (A.3) the market is efficient. Under these assumptions, it is shown by means of an arbitrage argument that the expected rate of r...

This paper is evolved to have insight of Plankton-Nutrients interactions in the presence of delay in the growth term of phytoplankton species .The conditions for asymptotic stability about endemic equilibrium are derived in the absence of delay.The Nyquist criteria is used to estimate the length of delay to preserve stability .Analytic criterion for the existence of hopf-bifurcation is also dis...

Firms sometimes try to “poach” the current customers of their competitors by offering them special inducements to switch. We analyze duopoly poaching under both short-term and long-term contracts in two polar cases: either each consumer’s brand preferences are constant from one period to the next, or preferences are independent over time. With fixed preferences, poaching induces socially ineffi...

Thermochemical equilibrium and kinetic calculations for the trace gases CO, PH3, and SiH4 give three independent constraints on the water and total oxygen abundances of Saturn’s deep atmosphere. A lower limit to the water abundance of H2O/H2≥ (1.7 −0.4)×10 is given by CO chemistry while an upper limit of H2O/H2 ≤ (5.5 −2.5)×10 is given by PH3 chemistry. A combination of the CO and PH3 constrain...

This article presents a case study describing how one nursing doctoral program faculty has identified, organized, and taught the disciplinary knowledge component of the curriculum. Three foci were chosen: health promotion and risk reduction; acute, critical, and long-term care; and systems. Faculty groups designed each focus to capitalize on current faculty research strengths and did not use a ...
