Full text linkThe aim of this article is to show how it is possible to integrate stories and ICT in Content Language Integrated Learning (CLIL) for English as a foreign language (EFL) learning in bilingual schools. Two Units of Work are presented. One, for the second year of Primary, is based on a Science topic, ‘Materials’. The story used is ‘The three little pigs’ and the computer program ‘JClic’. The other one is based on a Science and Arts topic for the sixth year of Primary, the story used is ‘Charlotte’s Web’ and the computer program ‘Atenex’.El propósito de este artículo es mostrar cómo se puede alcanzar la integración de cuentos y TIC en el Aprendizaje Integrado de Conocimientos Curriculares y Lengua Extranjera (AICLE) para el aprendizaje del inglés como lengua extranjera (ILE) en colegios bilingües. Se presentan dos Unidades: Una basada en un tema de Conocimiento del Medio Natural: “Materiales”, para 2º Curso de Primaria, a partir del cuento: “Los tres cerditos”, y el programa informático “JClic” y otra Unidad basada en un tema de Ciencias y Arte para 6º Curso de Primaria, a partir del cuento: “Charlotte’s Web”, y el programa informático: “Atenex”
For the time being, languages "alla bolognese"
Full text linkEl reciente escenario de certificaciones lingüísticas en las universidades españolas supone una confrontación sociolingüística de actitudes, creencias, temores y propuestas para organizar la consolidación formativa del alumnado en lenguas extranjeras. Como botón de muestra, se analiza el caso de la Universidad de Almería. En un panorama europeo necesitado de un hilo plurilingüe que sustente nuestra comprensión mutua, se propicia la privatización de acreditaciones lingüísticas para disponer un menú
idiomático que deben sufragar las familias. Asimismo, esa confrontación se percibe claramente en la vitalidad del viejo paradigma en la enseñanza-aprendizaje de lenguas, aunque empieza a hacer aguas ante el empuje del enfoque plurilingüe.The up-to-date panorama of language certification in the Spanish universities assumes a sociolinguistic showdown of mind-sets, beliefs, fears and motions to line-up the educational strengthening in the student body’s foreign languages. An in-depth case study of the University of Almería is being discussed/analyzed as a typical example. In a European scenario in need of a multilingual thread that supports our mutual understanding, privatization of linguistic accreditations are favoured in order to determine
a family financed idiomatic listing. In like manner, this face-off is clearly aprehended in the bounciness of the old paradigm in the teaching-learning process of languages, a pattern that is going on the rocks facing the boost of the multilingual focus
Estética y responsabilidad: una experiencia artística conectiva
No full textEste reporte de investigación sostiene que las prácticas artísticas basadas en la estética conectiva destacan la dimensión ética de la estética como fundamento filosófico del arte y muestran su capacidad transformado- ra hacia una sociedad más madura y solidaria, pues al desvincularse de las dinámicas de producción y consumo, el arte actúa como resistencia contra estos procesos homogeneizadores. Se presenta un caso de estudio que, junto con los comentarios de las personas participantes, revela cómo el arte puede tender un puente que conecta nuestra responsabilidad con el ámbito jurídicoThis research report argues that artistic practices based on connective aesthetics emphasize the ethical dimension of aesthetics as the philo- sophical foundation of art and demonstrate its transformative capaci- ty towards a more mature and supportive society. By disengaging from the dynamics of production and consumption, art acts as resistance against these homogenizing processes. A case study is presented which, along with the participants’ comments, reveals how art can bridge our responsibility with the legal real
Tooth loss during supportive periodontal care: A prospective study
Full text linkAim: To assess periodontal stability and the association between tooth- and patientrelated
factors and tooth loss during supportive periodontal care (SPC).
Materials and Methods: A prospective observational study was carried out on previously
treated periodontitis patients followed up for 5 years in SPC. The risk profile
(low, moderate, high) of each patient based on periodontal risk assessment (PRA)
scoring at baseline was evaluated, and tooth loss rates were analysed.
Results: Two hundred patients were included in the study, and 143 had 5-year follow-up
data available for analysis. The overall annual tooth loss per patient was 0.07 ± 0.14
teeth/patient/year. Older age, smoking, staging and grading were associated with
increased tooth loss rates. Most patients whose teeth were extracted belonged to the
PRA high-risk group. Both PRA and a tooth prognosis system used at baseline showed
high negative predictive value but low positive predictive value for tooth loss during SPC.
Conclusions: Overall, the tooth loss rate of periodontitis patients in this prospective
cohort study under SPC in private practice was low. Both tooth-based and patientbased
prognostic systems can identify high-risk cases, but their positive predictive
value should be improved.Grant from the Oral Dental

Evapotranspiration prediction for European forest sites does not improve with assimilation of in situ soil water content data
Full text linkLand surface models (LSMs) are an important tool
for advancing our knowledge of the Earth system. LSMs
are constantly improved to represent the various terrestrial
processes in more detail. High-quality data, freely available
from various observation networks, are being used to improve
the prediction of terrestrial states and fluxes of water
and energy. To optimize LSMs with observations, data
assimilation methods and tools have been developed in the
past decades.We apply the coupled Community Land Model
version 5 (CLM5) and Parallel Data Assimilation Framework
(PDAF) system (CLM5-PDAF) for 13 forest field sites
throughout Europe covering different climate zones. The
goal of this study is to assimilate in situ soil moisture measurements
into CLM5 to improve the modeled evapotranspiration
fluxes. The modeled fluxes will be evaluated using
the predicted evapotranspiration fluxes with eddy covariance
(EC) systems. Most of the sites use point-scale measurements
from sensors placed in the ground; however, for
three of the forest sites we use soil water content data from
cosmic-ray neutron sensors, which have a measurement scale
closer to the typical land surface model grid scale and EC
footprint. Our results show that while data assimilation reduced
the root-mean-square error for soil water content on
average by 56% to 64 %, the root-mean-square error for
the evapotranspiration estimation is increased by 4 %. This
finding indicates that only improving the soil water content
(SWC) estimation of state-of-the-art LSMs such as CLM5 is not sufficient to improve evapotranspiration estimates for forest
sites. To improve evapotranspiration estimates, it is also
necessary to consider the representation of leaf area index
(LAI) in magnitude and timing, as well as uncertainties in
water uptake by roots and vegetation parameters.LIFE programme

An umbrella review of systematic reviews on interventions of physical activity before pregnancy, during pregnancy, and postpartum to control and/or reduce weight gain
Full text linkBackground: The increasing prevalence of overweight and obesity worldwide
represents
a (chronic) complex public health problem. This is also seen among women
of childbearing age despite increased efforts to promote physical activity (PA) interventions.
Excessive gestational weight gain (GWG) is associated with negative health
outcomes for both mothers and offspring.
Objectives: To summarize current systematic reviews (SRs) on PA interventions during
pregnancy and postpartum to prevent excessive GWG and identify the most effective
approaches.
Search Strategy: A literature search was conducted on major electronic databases
(MEDLINE/Pubmed, Cochrane, Web of Science, Epistemonikos) from inception to
March 2023.
Selection Criteria: This study included SRs and meta-analyses
of studies involving
women aged 18 years or older from diverse ethnic backgrounds, who were either in
the preconception period, pregnant, or within 1 year postpartum and who had no contraindications
for exercise. Women with chronic diseases, such as pre-existing
diabetes
(type 1 or type 2) were excluded.
Data Collection and Analysis: Two reviewers extracted data from selected studies assessing
the impact of PA in preconception, pregnancy, and postpartum. Methodologic
quality was assessed with the AMSTAR-2
tool. A narrative summary of results addresses
relationships between PA and weight before, during, and after pregnancy,
informing future research priorities for preventing excessive weight gain. This study is
registered on PROSPERO (CRD420233946666).
Main Results: Out of 892 identified articles, 25 studies were included after removing
duplicates, unrelated titles, and screening titles and abstracts for eligibility. The results demonstrate that PA can help prevent excessive GWG and postpartum
weight retention. Structured and supervised moderate-intensity
exercise, at least
twice a week, and each session lasting a minimum of 35 min seems to provide the
greatest benefits.
Conclusions: Women who comply with the PA program and recommendations are
more likely to achieve adequate GWG and return to their pre-pregnancy
body mass
index after delivery. Further research is warranted to explore how preconception
PA influences pregnancy and postpartum outcomes given the absence of identified
preconception-focused
interventions.Universidad de Granada / CBUA
Time-Periodic Metallic Metamaterials Defined by Floquet Circuits
Full text linkIn this paper, we study the scattering and diffraction phenomena in time-modulated
metamaterials of metallic nature by means of Floquet equivalent circuits. Concretely, we focus on
a time-periodic screen that alternates between ‘‘metal’’ and ‘‘air’’ states. We generalize our previous
approaches by introducing the concepts of ‘‘macroperiod’’ and ‘‘duty cycle’’ to the time modulation. This
allows to analyze time-periodic metallic metamaterials whose modulation ratios are, in general, rational
numbers. Furthermore, with the introduction of the duty cycle, perfect temporal symmetry is broken within
the time modulation as the time screen could remain a different amount of time in metal and air states.
Previous statements lead to an enrichment of the diffraction phenomenon and to additional degrees of
freedom that can be exploited in engineering to control the reflection and transmission of electromagnetic
waves. Finally, we present some analytical results that are validated with a self-implemented finitedifference
time-domain (FDTD) approach. Results show that the scattering level and diffraction modes can
be controlled independently by means of the duty cycle and the modulation ratio, respectively, leading to an
efficient design of time-based pulsed sources and beamformers.Grant IJC2020-043599 /AEI/10.13039/501100011033European Union

Indagación sobre un paisaje cultural. La arquitectura del secado del tabaco en la configuración del territorio
No full textPara el conocimiento del territorio, existe la necesidad histórica de implantar un ordenamiento que evite tanto la dispersión de conocimientos, como la adopción de posturas radicales durante el procedimiento cognitivo del mismo. La concreción de saberes para la descripción y definición de un sistema territorial, ha enfrentado tradicionalmente a los geógrafos y a todos los profesionales implicados en el estudio del «lugar». La indagación sobre éste, ha de ser una actividad científica y no artística, por lo que debe adoptar los medios para dominar con rigor los datos obtenidos, definiendo la finalidad en la selección y fijando el método investigador, sin cercenar una posible interpretación original, siempre que ello no suponga una desviación que entre en contradicción con el objetivo perseguido.
En este contexto, la influencia humana en la construcción o la destrucción paisajística resulta muy difícil de delimitar, pues no existe un sistema de valores establecido y unánimemente reconocido. Este es el caso de la «Vega de Granada», en el que no se reconocen referencias concretas y sistemáticas para su delimitación. En este estudio y bajo el prisma del conocimiento geográfico formulado por Sauer, se pretenden establecer las pautas que definen esta comarca como paraje hospedador de un modelo de «paisaje cultural» a partir de la identidad arquitectónica del singular patrimonio industrial heredado de las «casas para el curado del tabaco».The knowledge of the territory, implies the historical need of establishing a regulation that avoids both the dispersion of knowledge, and the adoption of radical postures during the its cognitive procedure. The realization of knowledge for the description and definition of a territorial system, has traditionally confronted the geographers and all the professionals involved in the study of the «place». The inquiry on this one, must be a scientific and non-artistic activity, so it should adopt the means to rigorously dominate the data obtained, defining the purpose in the selection and setting the research method, without curtailing a possible original interpretation, whenever it does not imply a deviation which contradicts the objective pursued.
In this context, human influence on the construction or the destruction of landscape is very difficult to delimit, since there is no established and unanimous recognized value system. This is the case of the «Vega de Granada», which does not recognize specific and systematic references for its delimitation. In this study and under the prism of the geographical knowledge formulated by Sauer, it is intended to establish the guidelines that define this region as a place which hosts a model of "cultural landscape", from the architectural identity of the singular industrial heritage inherited of «tobacco curing houses».Departamento de Expresión Gráfica Arquitectónica y en la IngenieríaDepartamento de Construcciones Arquitectónica
Cognitive endurance after intense physical effort
No full textPrevious research has primarily examined the effects of cognitive exertion on subsequent physical performance,
yet the reciprocal relationship—how intense physical exercise influences cognitive endurance performance—remains largely unexplored. This study investigated the behavioral, subjective, and neurophysiological
effects of maximal aerobic effort on sustained cognitive endurance performance.
In a pre-registered, within-participant design, 29 physically active participants completed a cognitive task to
failure following either exhaustive running at 90 % of their maximal aerobic speed or a 10-minute walking
control condition. Electroencephalography (EEG) recorded brain activity, brain complexity was assessed, and
subjective experiences were analyzed using the Temporal Experience Tracing (TET) method.
Results indicated that maximal aerobic effort significantly reduced maximal force capacity and increased
perceived exertion compared to the control condition, confirming a higher physiological workload. However, no
significant differences were observed in cognitive task duration between conditions (control: 4755.8 s, 95 % CI
[3326.8–5107.8]; experimental: 4308.2 s, 95 % CI [3902.9–5481.2]; BF₁₀ = 0.329). Subjective experience
analysis revealed two distinct task-demand states, with comparable time allocation across conditions. EEG analyses indicated a decrease in brain complexity following exhaustive exercise, suggesting a physiological shift,
yet cognitive performance and subjective experience remained unaffected.
These findings provide no evidence that intense physical exercise negatively impacts cognitive endurance.
Despite alterations in physiological and neural markers, participants sustained cognitive effort to failure with no
significant decline in performance.Community of Madrid – (EXER-NIBS project, Ref. V1159)MICIU/AEI/10.13039/501100011033 – ERDF/EU (PID2023-152807NA-I00
Palatability changes during attenuation of flavor neophobia assessed with licking microstructure and taste reactivity
No full textNovel flavors elicit a neophobic response, which attenuates as they are recognized as safe. The attenuation of
taste neophobia has been widely studied through measuring overall intake, however, changes in hedonic value
have not been systematically considered. We conducted two experiments to assess, in both male and female
Sprague-Dawley rats, the hedonic changes across a six-day attenuation of the neophobia process using two
different methods. In the first experiment, we analyzed the microstructure of licking, which affords measuring
both consumption and hedonic value at the same time. This study used animals heterozygous for Cacna1c (a key
genetic risk factor for multiple psychiatric disorders associated with anhedonia) and wild type controls. In the
second experiment, we used the taste reactivity test. The analysis of licking microstructure, but not the taste
reactivity test, was sensitive to hedonic value changes during attenuation of the neophobia. Females showed
more hedonic reactivity than males in both experiments, and there was no effect of the Cacna1c manipulation.
The findings highlight the importance of considering hedonic factors in the attenuation of neophobia process.
The difference between the hedonic assessment methods in the sensitivity to hedonic changes during attenuation
of neophobia is discussed, although this is complicated by differences in the procedures themselves (e.g.
voluntary vs involuntary consumption).MCIN/AEI/10.13039/501100011033 (PID2020-114269GB-I00)Junta de Andalucía (BSEJ.514.UGR20)MECD (FPU16/06017)Medical Research Council (MR/RO11397/1)Universidad de Granada / CBUA (Open access
