En esta investigación se explora el proceso de aprendizaje de los futuros profesores que participaron en una asignatura de formación inicial de profesores de matemáticas de secundaria de la Universidad de Granada, España. Para ello, el autor introduce la noción…

We formalize a theoretical approach to industrial agglomeration and concentration phenomena using Agent-Based Modeling. The main thesis is that spatial economic dynamics of many industries can be explained from evolutionary principles, taking into account the variety of firm behaviors, selection…

Inclement climate conditions have made the Arctic Ocean logistically difficult to study, and thus, our historical knowledge of Arctic Ocean processes are limited. Recent observations indicate rapid and abrupt changes in climate. These changes are thought to includes rising temperatures,…

En este trabajo se presenta una metodología basada en tecnologías de representación, anotación y procesamiento semántico para la evaluación de preguntas abiertas o desarrollo en e-learning. Dicha metodología se fundamenta en la anotación semántica de los cursos, de las preguntas…

The mycoparasite Stachybotrys elegans represents a potential biocontrol agent of Rhizoctonia solani, the causal organism of potato stem canker. The differential expression of two mycoparasitism-induced genes was monitored in S. elegans during interactions with its host, Rhizoctonia solani, and a…

Curriculum reform emphasizes the importance of inquiry instruction for learners. For inquiry-oriented curriculum to occur, attention must be focused on teacher education. Using a mixed-methods design, I investigated if and how groups of student teachers who receive different types of…

An increasing number of applications require high-resolution images in situations where the access to the sensor and the knowledge of its specifications are limited. In this thesis, the problem of blind super-resolution is addressed, here defined as the estimation of…

Daughters of gestational diabetes (GDM) affected pregnancies are at greater risk for the development of type 2 diabetes mellitus (DM) later in life. Adiponectin is an early marker of DM risk. Dietary fat quality has been proposed to be involved…

This study attempts to expand existing knowledge on the relationship between biodiversity and ecosystem functioning, by studying a four year old tropical tree plantation. The growth of trees coming from monocultures, three species mixtures and six species mixtures was compared.…

We show that the long-standing assumption of "no-communication" between the provers of the two-prover model is not sufficiently precise to guarantee the security of a bit commitment scheme against malicious adversaries. Indeed, we show how a simple correlated random variable,…
