    [Resumen] Graellsia isabellae (Lepidoptera: Saturniidae) es un insecto de hábitos nocturnos que se encuentra en pinares de montaña de España (Pirineos occidentales y orientales, Sistema Central, Montañas Béticas y Sistema Ibérico), Francia (Alpes y vertiente francesa de los Pirineos) y Alpes suizos. Este Trabajo de Fin de Grado evalúa el origen introducido o autóctono de la población de G. isabellae localizada en Sousillon (Canton du Valais, Suiza) utilizando para ello información mitocondrial (gen COI) y nuclear (ocho loci microsatélites) y comparando su acervo genético con el de una población constatadamente introducida (Schallberg, Suiza), la única localidad conocida en la vertiente norte de los Pirineos (Custoja, Francia) y datos de otras poblaciones tomados de la bibliografía. Se comprobó que la población de Custoja es de origen natural, compartiendo características mitocondriales y nucleares con las demás poblaciones de los Pirineos orientales. La presencia de un único haplotipo ibérico pero componente nuclear francesa en Sousillon se debe a su origen introducido a partir de ejemplares de Schallberg, procedentes en su mayoría de los Alpes franceses con una contribución ibérica minoritaria.[Abstract] Graellsia isabellae (Lepidoptera: Saturniidae) is a nocturnal insect found in pinetree forests of Spain (western and eastern Pyrenees, Central Iberian System, Betic Mountains and Eastern Iberian Systema), France (Alps and northern slope at the Eastern Pyrenees) and Swiss Alps. The present work evaluates the origin (natural vs introduced) of the Swiss population of Sousillon (Canton du Valais). For this I have used mitochondrial (COI gene) and nuclear (eight microsatellite loci) information and compared Sousillon with a truly introduced population (Schallberg, Switzerland), the only known locality in the northern slope of the Pyrenees (Custoja, France) as well as other already published populations. The natural population of Custoja shared mitochondrial and nuclear features with the other populations from the eastern Pyrenees. The finding of a single Iberian haplotype in Sousillon, despite a nuclear affinity with the French Alps, is due to an introduction from Schallberg. In fact, our data confirm that Schallberg is the result of an introduction mainly from the French Alps, with a minor Iberian contribution.Traballo fin de grao (UDC.CIE). Bioloxía. Curso 2014/201

    Introduction: The adaptation of universities to the new guidelines set by the European Higher Education Area implies relevant changes. Among them, a teaching model more focused on the student and his or her learning than on the teacher and the subject, new active teaching-learning methodologies and the development of competences through the acquisition of learning outcomes; all with the aim of contributing to the integral formation of the university student. The integral formation, enabling each student to discover and realize their own life project, is nourished by educational accompaniment and the development of competences. A concrete form of educational accompaniment is mentoring. The objective of this study is to evaluate the formative effectiveness of an innovative mentoring program in the development of transversal competences as a means to achieve the ultimate mission of the university: to provide a comprehensive education to students. Methods: The design of this research is quasi-experimental (pretest-posttest). The sample consists of more than 300 first-year students of the Universidad Francisco de Vitoria who participated in the mentoring program. A questionnaire on transversal competences and group interviews were used as measurement instruments. Results: The results showed significant differences in the level of acquisition of intrapersonal competences between the pre-treatment and post-treatment periods, in favor of the latter. This fact suggests that students improved their level of intrapersonal competences thanks to the mentoring program. These results are subsequently supported by the analysis of the group interviews. Discussion: Therefore, it can be concluded that this type of mentoring program is a valid example for the development of intrapersonal competences, which in turn contributes to the integral formation of the student.post-print912 K

    There is a deficit in character education research in Latin America and a lack of clarity about conceptual issues relevant to values and virtues. This lack of conceptual clarity has practical importance. The research sought to investigate empirically how school managers and teachers understand and practice character education, with particular attention to the distinction between educating values and virtues. The study was carried out during the first semester of 2022 on a sample of 160 schools in 17 countries, mainly in Christian schools in Spain and Mexico. The results show that there are differences according to the type of school and country. There are important findings regarding the concept of virtue and its relation to the concept of value, which virtues and values are most relevant for schools to teach, and which are the most used strategies in character education programmes. The research points to moral education as a central theme in schools, which considers both virtue and values education. There is a genuine interest on training teachers in virtue education.pre-print1755 K

    The effect of teacher leadership on students’ purposeful learning.

    Get PDF
    Teaching leadership is a key factor for students’ learning and flourishing, and it occurs in an asymmetrical and interpersonal relationship. This research seeks to characterize the teaching leadership of high school teachers through the influence they exert on their students. It is not based on the teacher’s self-perception but on the experience that the students have had. For this purpose, a qualitative study was carried out in Spain with 200 first-year university students in which they answered four questions about the teacher who most influenced them during their high school. The results point to five leadership traits or styles that are not mutually exclusive: empathetic leadership, comforting leadership, motivating leadership, exemplary leadership, and wise leadership. In addition, moments of weakness and vulnerability in students are those that most favour the influence of the teacher in their lives, encouraging vital learning in them. This study highlights the importance of teacher leadership for student character education.post-print1771 K

    El hepatocarcinoma (CHC) es un problema médico relevante por su elevada mortalidad. La mayoría presenta una cirrosis hepática subyacente. En España el VHC constituye el principal factor de riesgo. El cribado con ecografía abdominal cada 6 meses en cirróticos es fundamental para detectar pacientes en estadios precoces y mejorar la supervivencia a largo plazo. Los objetivos de nuestro trabajo son: describir las características de los pacientes diagnosticados de CHC en el área Valladolid Oeste; conocer el estadio tumoral al diagnóstico; conocer el tratamiento recibido; determinar la supervivencia global y según estadio; valorar la tasa de cribado en los pacientes diagnosticados y el efecto del cribado en la tasa de diagnóstico en estadios precoces y en la supervivencia.Grado en Medicin

    [EN] The continuous increase in cultural tourism, together with the deficient planning of public use, increases the risk of heritage resource degradation. Currently, there are collaborative methodologies enabling all the agents involved in the conservation of a heritage site to work in a coordinated way (HBIM), such as in the management of public use. However, in this study, through a review of the scientific literature, the lack of a method and tool that allows sustainable conservation management and the planning of cultural tourism of heritage assets in a specific geographical environment is demonstrated. The objective of this research is thus to explore and identify the possibilities of interoperability between HBIM and GIS for the development of a protocol aimed at synchronizing the information concerning heritage architecture across the management and cultural tourism planning and preventive conservation. This protocol was implemented for three monumental buildings in the historic centre of the city of Valencia (Spain). This novel protocol provides a new technological system that fosters the cultural development and preservation and conservation of heritage assets through a single tool integrating HBIM and GISWe thank the Cathedral Chapter and the Rectorate and managers of the Royal Seminary College of Corpus Christi and the rectory church of San Juan del Hospital for their availability so that this research could be carried out. We thank Junshan Liu and Danielle Wilkens for their collaboration in collecting data from the Real Colegio Seminario.López González, MC.; G-Valldecabres, J. (2023).

    Bath construction at the Spanish Mediterranean seaside: maritime heritage for the coast environment

    Get PDF
    The construction of buildings holding baths along the Spanish seashore, not only supposed an enjoyment for affluent people but was a way of generating a new tourist landscape. The golden age of Spanish balneotherapy took place around the last third of the nineteenth century. Many sea bath structures were built at the Spanish Levante, but they have all now disappeared. Inside these constructions there were coffee-shops, theaters and casinos. People used to go there looking for therapeutic or medicinal healing, and also to find a place where they could forget their problems and daily routine. This research paper is part of a project conducted at the University of Alicante, and its main target has been to find historical documentation about these Mediterranean seashore buildings (Alicante and Murcia) in order to accomplish a cataloging that allowed us to study these architecture typologies. All the historical maps and plans, drawings and photographs used in our paper, not only offer us a romantic vision, they also convey a whole process of systematized execution. The construction system can be divided into permanent and removable structures. This removable feature and the simplicity of assembly were achieved thanks to the precarious concession carried out by the authorities at the maritime area. This paper shows the study of different architectural, structural and constructive solutions implanted in each one of these typologies characterized by the use of fixed and removable lightweight structures and the evolution of piling systems

    Investigating the Interstellar Medium Conditions of Star Formation in High Redshift Galaxies by studying Dust Emission and Emission lines

    This thesis presents the search for the \cii 158 μ\mum emission line, one of the brightest far-infrared (FIR) emission lines, in a selection of z>6z>6 (the Universe was less than 1 Gyr old) galaxies. These galaxies have been observed with CARMA and PdBI millimeter interferometers and no \cii nor continuum emission is detected. The estimated upper limits show that the \cii line in these galaxies is not as bright as in some galaxies with similar values of star formation rates at lower redshifts. These results indicate that the low metallicity expected for these type of galaxies could be the reason of the non-detection of \cii. For a lensed multiple-imaged galaxy (MACS0329-iD) observed with the ALMA millimeter interferometer a tentative detection of the \cii emission line with a 3.7σ3.7\sigma significance has been detected. This detection would put the galaxy at a spectroscopic redshift of z=6.17722±0.00005z=6.17722 \pm 0.00005, in agreement with the photometric redshift previously estimated. The galaxy is not detected in the continuum, with a 3σ3\sigma upper limit of 1.8 mJy at 158 μ\mum restframe. The ratio between the tentative observed \cii emission line and the far-infrared luminosity of >5.0×104>5.0\times10^{-4} puts this galaxy near what is typically found in the local star-forming galaxies. In conclusion, significantly deeper \cii observations than previously thought are need in the future to securely detect \cii emission in the highest redshift galaxies. This work also presents the search for lensed submillimeter galaxies with the goal of studying the faint population of dusty starbursting galaxies. Observations were made of 15 galaxy clusters using the bolometers LABOCA at APEX telescope and GISMO at IRAM 30 meters telescope. Of the 62 unique sources detected, we were able to find the galaxy counterpart to the far-infrared emission when was possible. Our sample of lensed submillimeter galaxies appears to be within the range of observed infrared luminosities at z2z2. When comparing the stellar masses and the SFR of our sample, they appear to agree well with the main-sequence of galaxies at z2z\sim2. This thesis presents the efforts of studying high redshift galaxies with submillimeter and millimeter observations and some techniques to better analyze and understand them
