    • Negative certainty 

      Ariso Salgado, José María (1) (Educational Philosophy and Theory, 01/2017)
      The definitions of negative knowledge' and the studies in this regard published to date have not considered the categorial distinction Wittgenstein established between knowledge and certainty. Hence, the important role ...
    • New improved convergence analysis for Newton-like methods with applications 

      Magreñán, Á. Alberto (1); Argyros, Ioannis K; Sicilia, Juan Antonio (1) (Journal of Mathematical Chemistry, 08/2017)
      We present a new semilocal convergence analysis for Newton-like methods using restricted convergence domains in a Banach space setting. The main goal of this study is to expand the applicability of these methods in cases ...
    • New improved convergence analysis for the secant method 

      Magreñán, Á. Alberto (1); Argyros, Ioannis K (Mathematics and Computers in Simulation, 01/2016)
      We present a new convergence analysis, for the secant method in order to approximate a locally unique solution of a nonlinear equation in a Banach space. Our idea uses Lipschitz and center-Lipschitz instead of just Lipschitz ...
    • On the election of the damped parameter of a two-step relaxed Newton-type method 

      Amat, Sergio; Busquier, Sonia; Bermúdez, Concepción; Magreñán, Á. Alberto (1) (Nonlineard Dynamics, 04/2016)
      In this paper, we are interested to justified two typical hypotheses that appear in the convergence analysis, |λ|≤2|λ|≤2 and z0z0 sufficient close to z∗z∗ . In order to proof these ideas, the dynamics of a damped ...
    • Prevalence and incidence of hepatitis delta in patients with chronic hepatitis B in Spain 

      Aguilera, Antonio; Trastoy, Rocío; Rodríguez-Calviño, Javier; Manso, Tamara; Mendoza, Carmen de; Soriano, Vicente (1) (European Journal of Gastroenterology & Hepatology, 09/2018)
      Background Hepatitis delta virus (HDV) is a defective agent that only replicates in the presence of the hepatitis B virus. Accordingly, HDV acquisition may occur as superinfection of HBsAg+ carriers or following acute dual ...
    • Relationship between cyberbullying roles, cortisol secretion and psychological stress 

      González-Cabrera, Joaquín (1); Calvete, Esther; León-Mejía, Ana (1); Pérez-Sancho, Carlota; Peinado, José M. (Computers in Human Behavior, 05/2017)
      Although cyberbullying is associated with different psychological problems, the role of biological markers of stress in cyberbullying has been relatively neglected. The aims of this study were: 1) to analyze the profile ...
    • Rutinas para trabajar la Historia en el aula a través de los archivos digitales: Una propuesta práctica 

      Lasala Navarro, Isabel (1); Gudín de la Lama, Enrique (1) (Revista de Historiografia, 2016)
      Hasta hace muy poco se ha considerado que la enseñanza de la historia consistía bá- sicamente en transmitir conocimientos históricos a los alumnos. Conocimientos que se reducían a narraciones del pasado y el correspondiente ...
    • Social4all: Definition of specific adaptations in Web applications to improve accessibility 

      González-Crespo, Rubén (1); Pascual-Espada, Jórdan; Burgos, Daniel (1) (Computers Standards and Interfaces, 11/2016)
      Web accessibility guidelines help developers to create websites which can more easily be used by people with different limitations. The principles and techniques of accessibility focus on the suitable use of standard Web ...
    • Stability analysis of a parametric family of iterative methods for solving nonlinear models 

      Cordero, Alicia; Gutiérrez, José M; Magreñán, Á. Alberto (1); Torregrosa, Juan Ramón (Applied Mathematics and Computation, 07/2016)
      A one-parametric family of fourth-order iterative methods for solving nonlinear systems is presented, proving the fourth-order of convergence of all members in this family, except one of them whose order is five. The methods ...
    • Stability study of eighth-order iterative methods for solving nonlinear equations 

      Cordero, Alicia; Magreñán, Á. Alberto (1); Quemada, Carlos; Torregrosa, Juan Ramón (Journal of Computational and Applied Mathematics, 01/2016)
      In this paper, we study the stability of the rational function associated to a known family of eighth-order iterative schemes on quadratic polynomials. The asymptotic behavior of the fixed points corresponding to the ...
    • Study of Factors Affecting the Choice Modal of Transportation in an Urban Environment Using Analytic Hierarchy Process 

      Fraile, Alberto (1); Sicilia, Juan Antonio (1); González-Crespo, Rubén (1); González, Alfonso (1) (Communications in Computer and Information Science, 2016)
      In modern economies it is essential a proper system of transport that enables population mobility and consequent accessibility to services. However, its current configuration is causing strong negative externalities and ...
    • The Choice of Local Food Products by Young Consumers: The Importance of Public and Private Attributes 

      Fernández-Ferrín, Pilar; Bande Videla, Belén (1); Calvo-Turrientes, Aitor; Galan-Ladero, M Mercedes (Agribusiness, 2017)
      In this paper, we propose an explicative model for the effective purchase of various brands of local products, incorporating private and public motivations into a causal chain and considering product availability as a ...
    • The Effect of Additional Exposure to the Unique Features in a Perceptual Learning Task Can Be Attributed to a Location Bias 

      Recio, Sergio; Iliescu, Adela; Berges, German; Gil-Nájera, Marta (1); de Brugada, Isabel (Journal of Experimental Psychology-Animal Learning and Cognition, 04/2016)
      It has been suggested that human perceptual learning could be explained in terms of a better memory encoding of the unique features during intermixed exposure. However, it is possible that a location bias could play a ...
    • The role of libraries in cultural centres Abroad: an insight 

      Gutiérrez Prieto, Juan José; Segado-Boj, Francisco (1) (New Library World, 2016)
