Challenges of online higher education in the face of the sustainability objectives of the united nations: Carbon footprint, accessibility and social inclusion
(Sustainability (Switzerland), 2019-10-01)
This article analyses three of the Sustainable Development Goals (SDGs) gathered by the 2030 Agenda and adopted by the United Nations, and how online educational models may help to reach these goals. Specifically, the three ...
Highly efficient family of iterative methods for solving nonlinear models
(Journal of Computational and Applied Mathematics, 2019-01-15)
In this study, we present a new highly efficient sixth-order family of iterative methods for solving nonlinear equations along with convergence properties. Further, we extend this family to the multidimensional case ...
Comprehensive evaluation of the tourism seasonality using a synthetic DP2 indicator
(Tourism Geographies, 2019-03-15)
Tourism plays an important role in the economic development of several regions over the world. Imbalances in the activity levels throughout the year will condition the positive effects generated by the sector given that ...
Salesperson coping with work-family conflict: The joint effects of ingratiation and self-promotion
(Journal of Business Research, 2019-02)
Impression management tactics have recently been identified as effective strategies for coping with work stressors. However, despite the evidence that using a combination of tactics can provide more favorable outcomes than ...
Optimal Fourth-Order Weerakoon–Fernando-Type Methods for Multiple Roots and Their Dynamics
(Mediterranean Journal of Mathematics, 2019-04-16)
In this paper, we present optimal fourth-order methods for finding multiple roots of non-linear equations, where the multiplicity is known in advance. These methods are based on the third-order method given by Weerakoon ...
Adult-onset hypothyroidism increases ethanol consumption
(Psychopharmacology, 2019-04)
RationaleOnly in Europe it can be estimated that more than 20 million of people would be affected by hypothyroidism in some moment of their life. Given that ethanol consumption is so frequent, it would be reasonable to ask ...
Extended local convergence for some inexact methods with applications
(Journal of Mathematical Chemistry, 2019-05)
We present local convergence results for inexact iterative procedures of high convergence order in a normed space in order to approximate a locally unique solution. The hypotheses involve only Lipschitz conditions on the ...
Biomass as Renewable Energy: Worldwide Research Trends
(Sustainability, 2019-02-01)
The world's population continues to grow at a high rate, such that today's population is twice that of 1960, and is projected to increase further to 9 billion by 2050. This situation has brought about a situation in which ...
Different methods for solving STEM problems
(Journal of Mathematical Chemistry, 2019-05)
We first present a local convergence analysis for some families of fourth and six order methods in order to approximate a locally unique solution of a nonlinear equation in a Banach space setting. Earlier studies have used ...
Voluntad de saber en el tiempo de la posverdad
(Educación XXI, 2019)
Introducción: la creciente popularización del término “posverdad” y la consolidación, más allá de los márgenes políticos, de la corriente de pensamiento que la toma por base, plantea unos desafíos educativos peculiares a ...
