Does everyone benefit equally from self-efficacy beliefs? The moderating role of perceived social support on motivation
(Sage Publications Inc, 2018-02)
This study investigated whether perceived goal support from family and friends may moderate the relationship between academic self-efficacy and motivational outcomes among early adolescent students recruited from a low-middle ...
Cylindrical and spherical solitary waves in an electron-acoustic plasma with vortex electron distribution
(Amer Inst Physics, 2018-04)
We consider the nonlinear propagation of electron-acoustic waves in a plasma composed of a cold electron fluid, hot electrons obeying a trapped/vortex-like distribution, and stationary ions. The basic nonlinear equations ...
Reductions of topologically massive gravity I: Hamiltonian analysis of second order degenerate Lagrangians
(Amer Inst Physics, 2018-01)
We present Skinner-Rusk and Hamiltonian formalisms of second order degenerate Clement and Sarioglu-Tekin Lagrangians. The Dirac-Bergmann constraint algorithm is employed to obtain Hamiltonian realizations of Lagrangian ...
