Educatio siglo XXI : revista de la Facultad de Educación

2021

¿Qué capacidades cartográficas posee el alumnado de primer ciclo de Educación Primaria si se tienen en cuenta sus experiencias personales? Para responder a esta cuestión se ha realizado un estudio de casos en 2º curso de Educación Primaria, donde se comparan las habilidades cartográficas de un grupo experimental en el que se ha intervenido con otro de control sin intervención. A la muestra se le aplica un pretest y un postest para que realice una representación pictórica de un itinerario y responda a cuatro cuestiones. Los resultados obtenidos se han categorizado según las clasificaciones propuestas por Lynch (1960), Boardman (1986) y Bale (1989) para el análisis del espacio geográfico. Las…

Microorganisms and Biotic Interactions

2014

SPE IPM; Most ecosystems are populated by a large number of diversified microorganisms, which interact with one another and form complex interaction networks. In addition, some of these microorganisms may colonize the surface or internal parts of plants and animals, thereby providing an additional level of interaction complexity. These microbial relations range from intraspecific to interspecific interactions, and from simple short-term interactions to intricate long-term ones. They have played a key role in the formation of plant and animal kingdoms, often resulting in coevolution; they control the size, activity level, and diversity patterns of microbial communities. Therefore, they modul…

TAX COMPETITION E GIUSTIZIA SOCIALE NELL'UNIONE EUROPEA

2019

Il fenomeno della concorrenza fiscale tra Stati è ormai noto da tempo, ma è soprattutto negli ultimi quindici anni che esso è cresciuto fino ad assumere una dimensione di particolare rilievo. A questo fenomeno non è rimasta estranea l’Europa, ove la tax competition si è sviluppata fondamentalmente attraverso due processi. Il primo è la <> delle aliquote dell’imposta sul reddito delle società. Basti pensare, a riguardo, che nel periodo 1995-2014, il tasso medio UE-28 di quelle aliquote è diminuito di 12 punti percentuali. Il secondo processo, che ha riguardato principalmente le multinazionali di più grosse dimensioni (e, prime fra esse, quelle del settore digitale) è noto come Base Ero…

Environmental values and customer-perceived value in industrial supplier relationships

2017

This study addresses a gap in the research on supply channel management by integrating environmental values and value creation in the context of buyer-supplier relationships. This study has two objectives: (i) to explore the environmental values structure of industrial customers, and (ii) to test the effect of environmental values on overall value perceptions. The effect of customer's environmental values on the supplier's environmental image and customer-perceived value is tested with structural equation modeling using the PLS method. The empirical analysis is based on a global sample of industrial companies that have a high impact on the environment (n = 121). Key findings of this study a…

Data-Driven Interactive Multiobjective Optimization Using a Cluster-Based Surrogate in a Discrete Decision Space

2019

In this paper, a clustering based surrogate is proposed to be used in offline data-driven multiobjective optimization to reduce the size of the optimization problem in the decision space. The surrogate is combined with an interactive multiobjective optimization approach and it is applied to forest management planning with promising results. peerReviewed

Ciudadanía democrática: ética, política y religión. XIX Conferencias Aranguren

2011

This article is comprised of two parts, bound together by the concept of <i>democratic citizenship</i>. The first part attempts to design the lines of <i>deliberative democracy</i> as the most appropriate model to embody the actual substance of democracy. That is why it presents the sense of deliberative democracy, its traits, its advantages compared with other models, the conditions for its start-up, its limits and the specific type of deliberative democracy that would be more adequate, and which receives the name of «communicative democracy»; all of this by way of dialogues with its main representatives. The second part addresses the specific questions of the <i…

The spatiotemporal dimension of doctoral education : a way forward

2020

For an individual doctoral student, doctoral education happens in multiple spaces across a considerable amount of time. However, the existing literature and conceptualisations of doctoral education do not adequately address the spatiotemporal dimension related to it. By using the concept of scales, this article examines how the social action of doing doctoral studies is affected by space and time. As a mode of inquiry, I use nexus analysis, which allows the analyst to spotlight issues that routinely go unnoticed by scholars, policy-makers but also doctoral students themselves. Based on the analysis, I argue that to theorise doctoral education further, its spatiotemporal dimension has to be …

A Mission Impossible? Learning the Logic of Space with Impossible Figures in Experience-Based Mathematics Education

2016

Most visual effects based on mathematically and physically describable phenomena and formalizable processes. Creating visual illusions, paradox structures and ‘impossible’ figures through playful and artistic procedures, holds an exciting pedagogical opportunity for raising students’ interest towards mathematics and natural sciences and technical aspects of visual arts. The Experience Workshop Math-Art Movement has a number of pedagogical methods, which are connected to visual paradoxes and perspective illusions. In the first part of our article, we introduce classroom exercises connected to the Hungarian artist Tamás F. Farkas’s paradox structures and impossible figures. There are certain …

The impact of variable hatching rates on parasite control: a model of an aquatic ectoparasite in a Finnish fish farm

2006

Summary 1 Many parasites of medical and veterinary importance infect via free-living stages that undergo a period of development in the environment before seeking a host. Frequently, considerable variation is observed in the development rates of these stages, such that some individuals may be considered to occupy distinct subpopulations, similar to a plant's seed bank. Under certain conditions, these subpopulations may act as a reservoir for the parasite, buffering it from the impact of management strategies and reducing control success. 2 We assessed the impact of intraspecific variation in development rates on parasite control by developing a population dynamic model of the ectoparasite A…
