The Environmental Attitudes and Behaviours of European Golf Tourists

Environmental attitudes and behaviours have received relatively little attention in golf tourism, compared to other tourism research areas. Golf tourism provides products and services based on nature, and they should focus on the environment. Golf has become increasingly important in the development of European tourism within the last decade. Moreover, golf is one of the primary motivations for European tourists in the sports tourism sector. This study is based on a sample of 431 golf tourists, from different nationalities, who visit Andalusia, Spain. This research examines the relationship between environmental attitudes and behavioural intentions for three subsamples of European nationalities: British, German, and Spanish. This relationship was corroborated in the three subsamples. However, the national citizenship of European golf tourists was not a moderator effect on the relationship between environmental attitudes and behavioural intentions

Un cuerpo propio* Performatividad(es) en la(s) identidad(es) infantil(es)

“Un(os) cuerpo(s) propio(s)*. Performatividades en la identidades infantiles” es una reflexión sobre la infancia. Esta etnografía pretende adoptar una mirada heterodoxa de las personas en edades comprendidas entre los cuatro y los seis años. Para ello, se cuestiona las frecuentes estandarizaciones homogeneizadoras de dichas personas. Dicho cuestionamiento tiene la finalidad de adoptar otra forma de mirar a esas personas; una mirada que nos permita mostrarlas como un grupo vivo y dinámico, que tiene agencias discursivas propias, específicas y múltiples. Agencias que adoptan diferentes formas en su interacción en el contexto social, cultural, político y económico. Esta mirada observa a la infancia como un grupo que, en interacción, moldea su propia y diversa identidad cultural en lo que se refiere al sexo, al género y a la “raza”, atravesadas, todas ellas, por la tensión que experimentan con la adultez

El present treball es centra en l’anàlisi de l’obra de les plantes soterrani de l’edifici d’ampliació de l’Escola Tècnica Superior d’Enginyeria Industrial de Barcelona realitzada mitjançant lloses i bigues posttesades. Per fer possible aquest estudi ha estat necessària tota una recerca bibliogràfica prèvia sobre els antecedents del sistema de posttesat, és a dir, el formigó pretensat i totes les seves variants. Tot aquest treball de recerca queda reflectit a la primera part d’aquest document, fent especial èmfasi a les aplicacions de les lloses posttesades en edificació tractant tots els criteris de projecte i la seva posada en obra que li són propis. A la segona part d’aquest document es desenvolupa la descripció, estudi i anàlisi del cas concret. Aquí tractem tots els conceptes assolits amb anterioritat aplicats a un cas pràctic. Per últim, es proposa una guia dels diferents passos a seguir a l’hora de controlar l’execució i la qualitat en qualsevol altra obra d’aquestes característiques

Extending FuzAtAnalyzer to approach the management of classical negation

FuzAtAnalyzer was conceived as a Java framework which goes beyond of classical tools in formal concept analysis. Specifically, it successfully incorporated the management of uncertainty by means of methods and tools from the area of fuzzy formal concept analysis. One limitation of formal concept analysis is that they only consider the presence of properties in the objects (positive attributes) as much in fuzzy as in crisp case. In this paper, a first step in the incorporation of negations is presented. Our aim is the treatment of the absence of properties (negative attributes). Specifically, we extend the framework by including specific tools for mining knowledge combining crisp positive and negative attributes.Universidad de Málaga.

From an implicational system to its corresponding D-basis

Closure system is a fundamental concept appearing in several areas such as databases, formal concept analysis, artificial intelligence, etc. It is well-known that there exists a connection between a closure operator on a set and the lattice of its closed sets. Furthermore, the closure system can be replaced by a set of implications but this set has usually a lot of redundancy inducing non desired properties. In the literature, there is a common interest in the search of the mini- mality of a set of implications because of the importance of bases. The well-known Duquenne-Guigues basis satisfies this minimality condition. However, several authors emphasize the relevance of the optimality in order to reduce the size of implications in the basis. In addition to this, some bases have been defined to improve the computation of closures relying on the directness property. The efficiency of computation with the direct basis is achieved due to the fact that the closure is computed in one traversal. In this work, we focus on the D-basis, which is ordered-direct. An open problem is to obtain it from an arbitrary implicational system, so it is our aim in this paper. We introduce a method to compute the D-basis by means of minimal generators calculated using the Simplification Logic for implications.Universidad de Málaga.

CAISL: Simplification Logic for Conditional Attribute Implications

In this work, we present a sound and complete axiomatic system for conditional attribute implications (CAIs) in Triadic Concept Analysis (TCA). Our approach is strongly based on the Simplification paradigm which offers a more suitable way for automated reasoning than the one based on Armstrong’s Axioms. We also present an automated method to prove the derivability of a CAI from a set of CAI s.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

Two absolute integral measurements of the Au-197(n,γ) stellar cross-section and solution of the historic discrepancies

This work has been supported by the Spanish projects FIS2015-69941-C2-1-P and FPA2016-77689-C2-1-R, (MINECO-FEDER,EU),A-FQM-371-UGR18 (Programa Operativo FEDER Andalucia 2014-2020), and the Spanish Association Against Cancer (AECC) (Grant No. PS16163811PORR).The Maxwellian averaged cross section (MACS) for Au-197(n,gamma) is used in neutron capture cross section measurements as a reference for reactions important for astrophysics, reactor and dosimetry applications. The traditionally adopted value for this reference cross section, in the energy range relevant for astrophysical (3 < E (n) < 200 keV), was obtained by Ratynski and Kappeler in 1988. However, the MACS calculated using the 2006 standards evaluation is approximately 6 % above the Ratynski and Kappeler (R&K) evaluation. Because of this discrepancy new experiments and reanalyses were done in an attempt to resolve the problem. In 2011 we started as well a series of integral experiments (activation) for determining the MACS -30 (kT=30 keV) of Au with two different Maxwellian neutron spectra: i) QMNS-25 (as R&K) and ii) MNS-30 (new method). Our results agree with those obtained with the standard evaluation. At present (2018), the updated MACS -30 has been included as standard Here we present the results of our measurements and the reasons for the lower value of the R&K measurement.Spanish projects (MINECO-FEDER,EU) FIS2015-69941-C2-1-P FPA2016-77689-C2-1-RSpanish Association Against Cancer (AECC) PS16163811PORRPrograma Operativo FEDER Andalucia 2014-2020 A-FQM-371-UGR1

Mediciones de rompimiento electrostático en separaciones micrométricas

La continua miniaturización de dispositivos electrónicos y electro-mecánicos ha permitido el estudio de efectos no visibles a macroescalas, como es el caso del comportamiento de electrodos separados a microescala. Se presenta aquí el comportamiento de electrodos de aluminio a presión atmosférica para un rango de separaciones de 1 mm a 22 mm. Convencionalmente, el comportamiento de electrodos se describe a partir de la curva de Paschen. Los resultados demuestran que, a separaciones menores de 4 mm, el voltaje de rompimiento en los electrodos decae drásticamente y no presenta un mínimo como lo predice la curva de Paschen. Esta modificación establece condiciones críticas de operación en dispositivos basados en electrodos con separaciones a microescalas./ The continuous miniaturization of electronic and electromechanical devices has allowed the study of non-visible effects on macroscales, as it is the case of the behavior of microgap separated electrodes. The behavior of aluminum electrodes at atmospheric pressure appears here for a rank of separations of 1 mm to 22 mm. The Paschen curve is conventionally used to describe the behavior of electrodes. The results demonstrate that at separations smaller than 4 mm the breakdown voltage in the electrodes decays dramatically and it does not present a minimum as predicts the Paschen curve. This modification establishes critical conditions of operation in devices based on electrodes with microgap separations
