El Canal de Castilla. Un proyecto de paisaje con perspectiva ambiental

El paisaje, por su carácter globalizador y por las posibilidades educativas que ofrece ha ido ganado terreno en el quehacer de la Educación Primaria. Las distintas perspectivas del paisaje: geográfica, histórica, social, cultural, estética, sonora, literaria, matemática, ambiental, etc., se prestan a su inclusión en proyectos educativos de esta etapa ya que no solo permiten una gran diversidad de aprendizajes, sino también su desarrollo dentro y fuera del aula, conectando al alumnado con la realidad. Aprovechando el entorno próximo del Canal de Castilla se pretende trabajar el paisaje dentro y fuera del aula mediante una metodología basada en proyectos que fomente el trabajo individual y en grupo, la adquisición de valores de respeto por el medio ambiente y una consecución de actividades que posibiliten el desarrollo de las distintas competencias que se trabajan durante la etapa de primaria.Grado en Educación Primari

Satisfaction surveys improvement study: analysis of the variables that could bias its reliability

El Gabinet de Planificació, Avaluació i Qualitat (GPAQ) gestiona un sistema d'enquestes per avaluar el desenvolupament dels professors i les assignatures. Aquest sistema d'enquestes consta de dues enquestes diferents, una per a les assignatures i una altra per als professors, que es realitzen cada dos anys i són respostes pels estudiants de grau i màster de la Universitat Politècnica de Catalunya (UPC). Els resultats obtinguts d'aquestes enquestes s'utilitzen per avaluar la qualitat de les assignatures i la qualitat de l'ensenyament del professorat. Els resultats obtinguts poden afectar la carrera dels docents, ja que s'utilitzen en l'avaluació de promocions i també han de conduir a millores en la qualitat general de l'ensenyament. Si els resultats obtinguts de les enquestes estan esbiaixats d'alguna manera, les conclusions derivades no ajudaran a millorar i també podrien afectar negativament els professors o les assignatures. En el present estudi, s'analitzaran diferents variables que podrien afectar les enquestes de satisfacció per aclarir si hi ha algun biaix que pugui afectar la fiabilitat dels resultats obtinguts. S'analitzaran les enquestes realitzades en ESEIAAT durant els cursos 2016/17, 2017/18 i 2018/19.El Gabinete de Planificación, Evaluación y Calidad (GPAQ) gestiona un sistema de encuestas para evaluar el desempeño de los profesores y las asignaturas. Este sistema de encuestas consta de dos encuestas diferentes, una para las asignaturas y otra para los profesores, que se realizan cada dos años y son respondidas por los estudiantes de grado y master de la Universidad Politécnica de Cataluña (UPC). Los resultados obtenidos de estas encuestas se utilizan para evaluar la calidad de las asignaturas y la calidad de la enseñanza del profesorado. Los resultados obtenidos pueden afectar la carrera de los docentes, ya que se utilizan en la evaluación de promociones y también deben conducir a mejoras en la calidad general de la enseñanza. Si los resultados obtenidos de las encuestas están sesgados de alguna forma, las conclusiones derivadas de sus resultados no ayudarán a mejorar y también podrían afectar negativamente a los profesores o las asignaturas. En el presente estudio, se analizarán diferentes variables que podrían afectar las encuestas de satisfacción para aclarar si existe algún sesgo que pueda afectar la fiabilidad de los resultados obtenidos. Se analizarán las encuestas realizadas en ESEIAAT durante los cursos 2016/17, 2017/18 y 2018/19.The Office of Planning, Evaluation, and Quality (GPAQ) manages a survey system to assess the performance of the teachers and the subjects. This survey system consists of two different surveys, one for the subjects and another for the teachers, that are conducted biannually and are answered by the students of bachelor's and master's degrees of the Polytechnic University of Catalonia (UPC). The results obtained from these surveys are used to assess the quality of the subjects and the teaching quality of the staff. The obtained results can impact on the career of the teachers, as they are used as an input in promotions, and must also lead to improvements in the overall quality of the teaching. If the results obtained from the surveys are biased in any manner, the conclusions derived from their results will not help to improve and could negatively affect the teachers or the subjects. In the present study, different variables that could impact the teacher's surveys will be analyzed to clarify if there is any bias that could impact the reliability of the obtained results. Surveys conducted on ESEIAAT during the courses 2016/17, 2017/18, and 2018/19 will be analyzed

Study of UV filters in cosmetic products and environmental samples

The main objective of this thesis is to develop analytical methods to determine a kind of cosmetic ingredients, the UV filters, in the cosmetics themselves, and in environmental matrices such as waters and beach sand. For that purpose, microextraction techniques and chromatographic analysis were employed. Seven studies are exposed. The first two methods presented were developed to analyse UV filters in cosmetics, and they are based on pressurized liquid extraction (PLE) followed by gas or liquid chromatography-tandem mass spectrometry. The following three methods are related to the analysis of the same compounds in water samples by ultrasound assisted emulsification microextraction (USAEME) and solid phase microextraction (SPME). Finally, different methods dealing with the analysis of UV filters in beach sand are presented

Un sistema de diálogo multicanal para acceder a la información y servicios de las administraciones públicas

En este artículo se presenta un sistema de diálogo desarrollado para el proyecto HOPS. El proyecto HOPS tiene como objetivo facilitar el acceso a la información y servicios de las administraciones locales en los que el conocimiento de la aplicación está representado en una ontología. Esta representación permite gestionar la interacción con el usuario en modo oral o textual en diferentes lenguas. El gestor de diálogo utiliza las ontologías para decidir cuál será la siguiente interacción con el usuario, así como para generar en las diferentes lenguas las gramáticas, léxicos y mensajes que intervendrán en cada interacción. Esta forma de representar el conocimiento implicado en la comunicación permite la reutilización de los recursos desarrollados en diferentes aplicaciones.This article presents a dialogue system developed for the European project HOPS. Hops project focuses on facilitating the access to the information and services of local administrations using ontologies to represent knowledge. This representation allows managing the user interaction in textual and vocal mode in different languages. The dialogue controller uses ontologies both for managing user interactions and for generating grammars, lexicons and messages implied in communication. This way of representing knowledge implied in communication allows reusing developed resources in future applications

The use of domain ontologies for improving the adaptability and collaborative ability of a web dialogue system

Dialogue systems can be used for guiding the users accessing web services, enhancing the web usability. However, they are expensive to develop and difficult to adapt to different types of web services. The knowledge model of a web service can be seen as the basis to define the semantics of the information to be exchanged among the components of a dialogue system. This approach facilitates the integration of the different types of knowledge involved in human-machine communication and provides a unified framework easier to apply to new web services. Furthermore, the representation of the web service knowledge according to an ontology can enhance the reasoning capabilities of the underlying system. This article describes the use of domain ontologies in a mixed-initiative web dialogue system for improving both its adaptability and its collaborative ability.Peer ReviewedPostprint (published version

The behaviour of diborane-reduced fulvic acids in flash pyrolysis

7 pages, 3 figures, 1 table, 25 references.-- Publicado en el capítulo: Session 1: Isolation, Fractionation, and Characterization.-- Humic Substances in the Aquatic and Terrestrial Environment, Proceedings of an International Symposium, celebrado del 21-23, agosto, 1989 en Linköping, Suecia.-- Este volumen 33, referido en la Citación, consta de 514 páginas, 150 figuras y 57 tablas.It is suggested that the striking structural changes introduced in humic substances by reduction with diborane may be useful in studying the role of carboxyl groups in the behaviour of these substances in flash pyrolysis. In the preliminary results shown in this communication, pyrograms of two fulvic acids of different origins and the corresponding diborane reduced substances are compared. It was found that the diborane reduction was responsible for both qualitative and quantitative changes in the pyrolytic patterns of the fulvic acids. These patterns feflect the changes in the reactivity and structural stability of the fulvic materials caused by the disappearance of the carboxyl groups.Peer reviewe

Fulvic acids from particulate matter of a water-logged peatland

6 pages, 3 figures, 2 tables, 29 references.The presence of aggregates of humic substances (HS) with inorganic adsorbates in a lagoon located in Huelva (south Spain) is reported. The chemical nature of the fulvic acid (FA) fraction, extracted from the natural aggregate by treatment with chelating resins, has been investigated by physical and chemical methods. The results suggest that these FA are similar to FA from other aquatic environments. As revealed by FT-IR and NMR spectroscopies and mild oxidation with potassium persulfate, the FA contain predominantly in their structure polysaccharides and components derived from lignin.Peer Reviewe

Exploring the complementarity between foreign technology, embedded technology and increase of productive capacity

This study analyzes the complementarity of foreign technology acquired under license agreements, technology embedded in machinery and equipment and increase in a company’s productive capacity. We use panel data on Brazilian manufacturing companies from the World Bank Surveys. We used the random effects models, estimated by maximum likelihood. The results indicate that foreign technology, embedded technology and increase of productive capacity have a positive and significant impact on labor productivity. The complementarity test reveals that the relationship between the two technologies analyzed is conditionally substitutive and that the relationship between each of these technologies and increase of productive capacity is conditionally complementary.Junta de Extremadura | Ref.

Competing for the disability tourism market - A comparative exploration of the factors of accessible tourism competitiveness in Spain and Australia

© 2014 Elsevier Ltd. This paper seeks to address the research question of what factors make a destination competitive for the accessible tourism market. The research design is based on destination competitiveness theories. The objective is to formulate a ranking that can compare the competitiveness factors between two countries, with historical and appropriate data sets, in order to examine destination competitiveness for accessible tourism across the tourist regions of both countries. The current research examines the background of destination competitiveness theories, both generally and specifically, as they relate to the research contexts. The research design was developed to examine the underlying elements that facilitate accessible tourism experiences through factorial and cluster analyses, adapting the Crouch's model of competitiveness destination. The findings suggest that the competitiveness factors are different in determinance and importance, and are country-dependent. The climate, locale and tourist structure are the most important for Spain, whereas quality of services, brand and infrastructure are of great importance for Australia. The cluster analysis of the different tourist regions suggests the existence of three main stages. These stages where related to their accessibility level of offered tourism product and their policies
