This research paper explores the effectiveness of live coding as an active learning methodology in teaching programming, particularly in the context of diverse learning styles. Live coding, characterized by real-time coding demonstrations by instructors, has been increasingly adopted to enhance the learning experience in programming education. It o...

Since the Bologna Process was adopted, continuous assessment has been a cornerstone in the curriculum of most of the courses in the different degrees offered by the Spanish Universities. Continuous assessment plays an important role in both students’ and lecturers’ academic lives. In this study, we analyze the effect of the continuous assessment on...

In semiarid areas, precipitations usually appear in the form of big and brief floods, which affect the aquifer through water infiltration, causing groundwater temperature changes. These changes may have an impact on the physical, chemical and biological processes of the aquifer and, thus, modeling the groundwater temperature variations associated w...

In this paper, we study the problem of defining statistical parameters when the uncertainty is expressed using a fuzzy measure. We extend the concept of monotone expectation in order to define a monotone variance and monotone moments. We also study parameters that allow the joint analysis of two functions defined over the same reference set. Finall...

In this paper, we study the problem of constructing a fuzzy measure over a product space when fuzzy measures over the marginal spaces are available. We propose a definition of independence of fuzzy measures and introduce different ways of constructing product measures, analyzing their properties. We derive bounds for the measure on the product spac...

Socio-ecological systems are recognized as complex adaptive systems whose multiple interactions might change as a response to external or internal changes. Due to its complexity, the behavior of the system is often uncertain. Bayesian networks provide a sound approach for handling complex domains endowed with uncertainty. The aim of this paper is t...

Teaching processes have been changing in the lasts few decades from a traditional lecture-example-homework format to more active strategies to engage the students in the learning process. One of the most popular methodologies is the flipped classroom, where traditional structure of the course is turned over by moving out of the classroom, most basi...

Two-sample statistical tests are commonly used when deciding whether two samples can be considered to be drawn from the same population. However, statistical tests face problems when confronted to situations involving extremely large volumes of data, in which case the power of the test is so high that they reject the null hypothesis even if the dif...

Given a graph G and a vertex x 2 V (G), a vertex set S in V (G) is an x-geodominating set of G if each vertex v in V (G) lies on an x-y geodesic for some element y in S. The minimum cardinality of an x-geodominating set of G is defined as the x-geodomination number of G, gx(G), and an x-geodominating set of cardinality gx(G)is called a gx-set. It i...

The magnitude of the trends of environmental and climatic changes is mostly derived from the slopes of the linear trends using ordinary least-square fitting. An alternative flexible fitting model, piecewise regression, has been applied here to surface air temperature records in southeastern Spain for the recent warming period (1973–2014) to gain ac...

Given a graph $G$ and a vertex $x\in V(G)$, a vertex set $S \subseteq V(G)$ is an $x$-geodominating set of $G$ if each vertex $v\in V(G)$ lies on an $x-y$ geodesic for some element $y\in S$. The minimum cardinality of an $x$-geodominating set of $G$ is defined as the $x$-geodomination number of $G$, $g_x(G)$, and an $x$-geodominating set of cardina...

Dominating concepts constitute a cornerstone in Graph Theory. Part of the efforts in the field have been focused in finding different mathematical frameworks where domination notions naturally arise, providing new points of view about the matter. In this paper, we introduce one of these frameworks based in convexity. The main idea consists of defin...

In this paper, we propose a methodology for relevance analysis of performance indicators in higher education based on the use of Bayesian networks. These graphical models provide, at first glance, a snapshot of the relevant relationships among the variables under consideration. We analyse the behaviour of the proposed methodology in a practical cas...

Naive Bayes models have been successfully used in classification problems where the class variable is discrete. These models have also been applied to regression or prediction problems, i.e. classification problems where the class variable is continuous, but usually under the assumption that the joint distribution of the feature variables and the c...

In this paper we explore the use of Tree Augmented Naive Bayes (TAN) in regression problems where some of the independent variables are continuous and some others are discrete. The proposed solution is based on the approximation of the joint distribution by a Mixture of Truncated Exponentials (MTE). The construction of the TAN structure requires th...

Resumen En este artículo proponemos una metodología para el análisis de rele-vancia de indicadores de rendimiento basada en el uso de redes bayesianas. Estos modelos gráficos permiten obtener, a primera vista, las principales relaciones entre las variables a considerar. Analizamos el comportamiento de la metodología propuesta con un caso práctico,...

Naive Bayes models have been successfully used in classification problems where the class variable is discrete. Naive Bayes models have been applied to regres-sion or prediction problems, i.e. classification problems with continuous class, but usually under the assumption that the joint distribution of the feature variables and the class is multiva...

Resumen En los últimos años ha cobrado gran impor-tancia el uso de indicadores para describir el perl de las Universidades españolas en tér-minos tanto académicos como investigadores y económicos. Estos indicadores son utilizados para tomar decisiones de gran importancia, lle-gando a afectar incluso a aspectos de nancia-ción. Sin embargo, el número...

RESUMEN Realizamos un análisis del alumnado de la Universidad de Almería correspon-diente al curso académico 2000/2001 utilizando modelos gráficos probabilísti-cos. Estos modelos permiten el manejo de bases de datos con numerosas vari-ables de carácter heterogéneo. Los modelos propuestos pueden ser utilizados para tareas tales como la clasificación...
