Existence and Uniqueness of Positive Solution for a Boundary Value Problem of Fractional Order by J. Caballero, J. Harjani, K. Sadarangani

“…We are concerned with the existence and uniqueness of positive solutions for the following nonlinear fractional boundary value problem: D0+αu(t)+f(t,u(t))=0, 0≤t≤1, 3<α≤4, u(0)=u′(0)=u″(0)=u″(1)=0, where D0+α denotes the standard Riemann-Liouville fractional derivative. …”

Europa y Estados Unidos ante los Derechos Humanos en Cuba by Susanne Gratius

“…El caso cubano señala el alto grado de politización del tema de los derechos humanos en las relaciones internacionales, puesto que el debate se centra en la falta de derechos civiles y políticos o de las libertades democráticas en el único régimen autoritario de las Américas. Cuba demuestra, al mismo tiempo, que tanto las sanciones impuestas por Washington como el compromiso condicionado de la UE no han sido estrategias eficaces para promover los derechos humanos en la isla. …”
