The collision of feminisms, sexuality, and trafficking in persons in the Caribbean—A place for Kempadoo

Feminist Anthropology, EarlyView.
Abstract The existence and development of feminist scholarship and practice have been revisited by feminist anthropologists and sociologists exploring it among the gendered cultural and historical dynamics of the Caribbean. Feminist Caribbeanists’ pioneering efforts that fit within this theoretical family have challenged the Global North status quo to ...

Convergence analysis of the Chebyshev-Legendre spectral method for a class of Fredholm fractional integro-differential equations

, 2018
In this paper, we propose and analyze a spectral Chebyshev-Legendre approximation for fractional order integro-differential equations of Fredholm type. The fractional derivative is described in the Caputo sense.

Local Polynomial Regression and Filtering for a Versatile Mesh‐Free PDE Solver

International Journal for Numerical Methods in Fluids, EarlyView.
A high‐order, mesh‐free finite difference method for solving differential equations is presented. Both derivative approximation and scheme stabilisation is carried out by parametric or non‐parametric local polynomial regression, making the resulting numerical method accurate, simple and versatile. Numerous numerical benchmark tests are investigated for

Two highly accurate and efficient numerical methods for solving the fractional Liénard’s equation arising in oscillating circuits

Partial Differential Equations in Applied Mathematics
In this paper, we investigate the fractional model of the Liénard and Duffing equations with the Liouville-Caputo fractional derivative. These equations grow with the evolution of radio and vacuum tube technology, which describe oscillating circuits and ...
