This study examines the influence of psychological contracts on the relations between social ties and knowledge exchange in virtual teams. We empirically tested our model in a field study of virtual teams in a large, multinational R&D firm. Results of structural equation modeling suggest two important antecedents to psychological contracts of knowledge sharing: instrumental and relational embed...

this paper aims to study a generalized double sinh-gordon equation, which appears in several physical phenomena such as integrable quantum field theory, kink dynamics and fluid dynamics. lie symmetry analysis together with the simplest equation method is used to obtain exact solutions for this equation. moreover, we derive conservation laws for the equation by using two different approaches, na...

in this paper, we propose the chebyshev wavelet approximation for the numerical solution of a class of integro-differential equation which describes the charged particle motion for certain configurations of oscillating magnetic fields. we show that the chebyshev approximation transform an integral equation to an explicit system of linear algebraic equations. illustrative examples are included t...

Both single emitters and large area field (LAFEs) are generally characterized using the slope intercept of a Murphy–Good (or Fowler–Nordheim) plot, which used to extract enhancement factor emission area. Using shielding model that has been developed recently for LAFE, validity underlying assumption is investigated. It found in case contributions from as well rate at effective number superemitte...
