Diseño y validación de un modelo de competencias TIC docentes en Chile. Taxonomía para evaluar desempeños docentes en contextos educativos municipales de primer ciclo básico
La tesi que es presenta és un estudi que se centra en dissenyar un model de competències TIC per avaluar, en base a una taxonomia, els acompliments docents en Contextos Educatius, basat en una visió teòrico-pràctica, per optimitzar la integració curricular en el sistema educatiu xilè i les percepcions dels estudiants respecte a l’ús dels recursos tecnològics en els processos d'ensenyament-aprenentatge, ja que no existeix un model (a Xile) que avaluï en el context real el que els professors realitzen amb les TIC a l'aula, sent els seus processos avaluatius només instrumentals. La mostra es constitueix per professors de 10 escoles d'educació bàsica (primària) de Xile per a la recol·lecció de dades quantitatives i 5 escoles per les dades qualitatives, que van ser seleccionats a través d'un mostreig intencionat.
Els 5 objectius principals d’aquest treball són: diagnosticar la percepció sobre les Competències TIC dels docents xilens de primer cicle bàsic de la Región del Bío-Bío, Xile; identificar les percepcions dels estudiants de primer cicle bàsic, i directius respecte a l’ús de TIC que fan els professors en els processos d'ensenyament-aprenentatge; dissenyar un model de competències TIC per avaluar acompliments docents en contextos educatius, sobre la base d'una taxonomia teòric-pràctic que permeti avaluar-ne quantitativament i qualitativament; validar el model de Competències TIC per avaluar acompliments docents en Contextos Educatius; i finalment, transferir el model a la comunitat científica nacional i internacional i al sistema educatiu xilè.
Aquesta recerca s'aborda des d'un disseny inductiu amb un mètode basat en la teoria fonamentada a través d'una metodologia mixta. Els resultats subratllen el disseny del model, la seva validació a través d'usuari i expert per a la seva posterior difusió a la comunitat científica.
La finalitat és contribuir amb referents teòrics i pràctics a les redefinicions dels rols dels professors, aportant noves categoritzacions relacionades amb les Competències TIC en l'acompliment docent, amb el propòsit de disposar d'instruments de mesura qualitativa en contextos educatius xilens.Esta investigación tiene como objetivo diseñar un modelo de competencias relacionadas con el uso de las Tecnologías de la Información y Comunicación (TIC), con el fin de evaluar las actuaciones de los profesores en contextos educativos primarios a través de una taxonomía. Este modelo se basa sobre la base de una taxonomía teórico-práctica que permita evaluarlos. En primer lugar, para optimizar la integración curricular en el Sistema Educativo Chileno. En segundo lugar, para optimizar la percepción de los estudiantes relacionados con el uso de los recursos tecnológicos en el proceso de enseñanza y aprendizaje. Este modelo es el resultado de la revisión de la literatura donde no hay evidencia de que Chile cuenta con un modelo para evaluar las actuaciones de los profesores relacionados con el uso de las TIC en contextos educativos reales. La literatura muestra que los procesos de evaluación chilenos son sólo instrumentales. La muestra está compuesta por profesores de diez escuelas primarias de la región Bío - Bío en Chile, con el fin de recopilar datos cuantitativos. Así como, los profesores de cinco escuelas para reunir datos cualitativos. Ellos fueron seleccionados por un muestreo intencional.
Los cinco objetivos principales de este trabajo son: diagnosticar la percepción sobre las Competencias TIC de los docentes chilenos de primer ciclo básico de la Región del Bío-Bío, Chile; identificar las percepciones de los estudiantes de primer ciclo básico, y directivos respecto al uso de TIC que realizan los profesores en los procesos de enseñanza-aprendizaje; diseñar un Modelo de Competencias TIC para evaluar desempeños docentes en contextos educativos, sobre la base de una taxonomía teórico- práctica que permita evaluarlas cuantitativa y cualitativamente; validar el modelo de Competencias TIC para evaluar desempeños docentes en Contextos Educativos; y finalmente, transferir el modelo a la comunidad científica nacional e internacional y al sistema educativo chileno.
Esta investigación se aborda desde un diseño inductivo con un método basado en la teoría fundamentada a través de una metodología mixta. Los resultados subrayan el diseño del modelo, su validación a través de opinión de usuarios y de expertos para su posterior difusión a la comunidad científica.
La finalidad fue contribuir con referentes teóricos y prácticos a las redefiniciones de los roles de los profesores, aportando nuevas categorizaciones relacionadas con las Competencias TIC en el desempeño docente, con el propósito de disponer de instrumentos de medición cualitativa en contextos educativos chilenos.This research aims to design a model of competences related to the use of Information and Communication Technologies (ICT) in order to assess teachers’ performances in primary educational contexts through a taxonomy. This model is based on a theoretical and practical vision with two main purposes. First, to optimize the curricular integration in the Chilean educational system. Second, to optimize students’ perceptions related to the use of technological resources in the teaching and learning process. This model is the result of the literature review where there is no evidence that Chile counts with a model that assess teachers’ performances related with the use of ICT in real educational contexts. The literature shows that Chilean evaluative processes are just instrumental. The sample is made up by teachers of ten primary schools from the Bio – Bio region in Chile, in order to gather quantitative data. As well as, teachers from five schools to gather qualitative data. They were selected by an intentional sampling.
The main aims of this research are five. First, to diagnose the perception of Chilean primary teacher about ICT competences. Second, to identify the perception of primary students and head of schools related to the teachers’ use of ICT in the teaching and learning process. Third, to design a model of competences related to the use of ICT in order to assess teachers’ performances in primary educational contexts based on a theoretical and practical taxonomy that enables to assess them qualitatively and quantitatively. Fourth, to validate the model of competences. Finally, to transfer this model to the national and international academic community and to the Chilean educational system.
This research was developed using an inductive design based on grounded theory through mixed methods. Results highlight the model design and its validation through users and experts in order to disseminate it to the scientific community.
Finally, this research contributes with theoretical and practical references to the redefinitions of the teachers’ role. Since, it shows new categories related to the ICT competences in the teachers’ performance in order to provide qualitative measurement instruments in Chilean educational context
Environmental and energy problematic in the mediterranean irrigation regions framework
[EN] Agriculture is a significant user of water and energy in Mediterranean coasts of Europe, such as Spanish Mediterranean regions. Water implications of such irrigations are well known, but also energy must be considered when environmental implications are analyzed. Apart from this, Mediterranean region has its particular problematic framework related to irrigation issues. Often, the availability of irrigation is
determinant to the viability of farmers, and the energy implications must be considered when
determining the feasibility of small and big farms, particularly in the Mediterranean regions, where the
wide variety of customs in each group of irrigators and definitely, its specific weather conditions, typical
of a semi-arid zone. All these aspects are analyzed in this paper, as a state of the art determination of
problems and possible solutions in a regional scale. Some solutions presented in this paper can contribute with theoretical reductions of emission of greenhouse gasses until 174.10 tCO2/year in pumped systems and 58.49 tCO2/year in multipurpose systems.Romero, L.; Pérez-Sánchez, M.; López Jiménez, PA.

Dental management of patients with endocrine disorders
Introduction:
The endocrine system is responsible for hormonal secretion and is closely related to the central nervous system, as it diversifies its functions through the hypothalamus and pituitary glands. It controls physiological
processes and maintains homeostasis. The neuroendocrine system is responsible for adaptation to environmental
changes. Therefore, in dentistry, it is important to be aware of the risks and difficulties that may arise during the
dental management of patients with endocrine disorders, and that visits to the dental clinics often represent a
stressful situation.
Objectives:
To review the literature on oral manifestations and dental management in patients with endocrine disorders (disorders of the thyroid, parathyroid and adrenal glands).
Material and Methods:
For the literature review, we carried out a search in Pubmed / Medline database using limits
and keywords according to the controlled vocabulary “Medical Subject Headings” (MeSH). We obtained a total of
19 articles (ten literature reviews, one case-control study, and eight clinical case series).
Results and discussion:
We describe the most common oral manifestations in patients with endocrine disorders and
the special dental management that should be carried out on these patient
Present-day heat flow model of Mars
Until the acquisition of in-situ measurements, the study of the present-day heat flow of Mars must rely on indirect methods, mainly based on the relation between the thermal state of the lithosphere and its mechanical strength, or on theoretical models of internal evolution. Here, we present a first-order global model for the present-day surface heat flow for Mars, based on the radiogenic heat production of the crust and mantle, on scaling of heat flow variations arising from crustal thickness and topography variations, and on the heat flow derived from the effective elastic thickness of the lithosphere beneath the North Polar Region. Our preferred model finds heat flows varying between 14 and 25 mW m−2, with an average value of 19 mW m−2. Similar results (although about ten percent higher) are obtained if we use heat flow based on the lithospheric strength of the South Polar Region. Moreover, expressing our results in terms of the Urey ratio (the ratio between total internal heat production and total heat loss through the surface), we estimate values close to 0.7–0.75, which indicates a moderate contribution of secular cooling to the heat flow of Mars (consistent with the low heat flow values deduced from lithosphere strength), unless heat-producing elements abundances for Mars are subchondritic
Natural radiactivity from building materials in Spain
The industrial construction sector is very important in Spain. Building materials used in this industry are sources of radiation from natural radionuclides they contain. The European Commission published some recommendations to facilitate the trade of these materials in the E.U. The studies about this subject have increased notably during last years. This, probably, can be associated with the increase interest from natural radiation radiological risk on indoor exposure.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech.

Algal lipids reveal unprecedented warming rates in alpine areas of SW Europe during the industrial period
Alpine ecosystems of the southern Iberian Peninsula
are among the most vulnerable and the first to respond
to modern climate change in southwestern Europe. While
major environmental shifts have occurred over the last ~
1500 years in these alpine ecosystems, only changes in the
recent centuries have led to abrupt environmental responses,
but factors imposing the strongest stress have been unclear
until now. To understand these environmental responses, this
study, for the first time, has calibrated an algal lipid-derived
temperature proxy (based on long-chain alkyl diols) to instrumental
historical data extending alpine temperature reconstructions
to 1500 years before present. These novel results
highlight the enhanced effect of greenhouse gases on
alpine temperatures during the last ~ 200 years and the longterm
modulating role of solar forcing. This study also shows
that the warming rate during the 20th century (~ 0:18 ºC per
decade) was double that of the last stages of the Little Ice Age
(~ 0:09 ºC per decade), even exceeding temperature trends
of the high-altitude Alps during the 20th century. As a consequence,
temperature exceeded the preindustrial record in the
1950s, and it has been one of the major forcing processes of
the recent enhanced change in these alpine ecosystems from
southern Iberia since then. Nevertheless, other factors reducing
the snow and ice albedo (e.g., atmospheric deposition)
may have influenced local glacier loss, since almost steady
climate conditions predominated from the middle 19th century
to the first decades of the 20th century.This research has been supported by the Seventh

On the thermo-mechanical structure of the Martian lithosphere: the role of the crust
An adequate knowledge of thermal and rheological properties of crust and mantle is fundamental for deciphering and understanding the thermal state and interior evolution of a planetary body. Previously, indirect methods have been used to calculate heat flows for Mars. A commonly used indirect method is based on the relation between the thermal state of lithospheric rocks and their mechanical strength, usually related through the effective elastic thickness of the lithosphere or from the depth to the brittle–ductile transition beneath large thrust faults. The so-obtained heat flows are valid for the time when the lithosphere was loaded or faulted, and therefore when deduced from regions deformed in different ages provides information on the thermal evolution of Mars
