The Impact of GRIT on the Increase of Academic Motivation among 4th Grade Students
No full textThe current socio-economic trends leave a deep imprint on the educational process, directly
influencing the evolution of the didactic methodology. One of the fundamental objectives of modern
pedagogy is to teach the student to learn autonomously, throughout his whole life. This path of
personality development must take place in motivating conditions, ensure a thorough training, with
multiple connections to the fields of practical activity. Motivation is the foundation upon which
educational success is built. It represents an important mental process because it triggers and drives the
student's action.
Often, a student's success is attributed to their talent or luck in a particular field of activity, and
(perhaps) less to the effort and perseverance invested. In order to have the success that students want, the
three values that guarantee success on any level are perseverance, ambition and development, or in one
word grit.
The purpose of this research was to develop, implement and test the effectiveness of an intervention
program based on GRIT development activities regarding the development of academic motivation in 4th
grade students.
Following the re-evaluation of the participants involved in this research, the results showed
improvements both at the level of Grit and at the level of academic motivation. After calculating the
effect size, the program demonstrated its efficiency obtaining a d between .30 and 2.05
The best interests of the child and the right of parents to ensure that their children receive an education in accordance with their convictions. A case of ultra vires constitutional protection against judicial decisions
No full textEn este trabajo se analiza un supuesto especialmente controvertido que ilustra el proceder actual del Tribunal Constitucional, conforme al cual este se considera, a sí mismo, competente para efectuar una revisión plena de las resoluciones judiciales en garantía de los derechos fundamentales que son objeto de amparo extraordinario. Una forma de actuar que le hace fungir como «tribunal de tercera instancia», según se advierte, especialmente, en aquellas ocasiones en las que se invoca el art. 24 CE, precepto este potencialmente habilitante de una suerte de control general de las decisiones de los jueces y tribunales. De tal modo, el Tribunal Constitucional se inmiscuye en cuestiones de legalidad ordinaria, con el pretexto de adecuar la norma legal a los mandatos de la Constitución. Los excesos en los que así incurre, que, a menudo, le 180 JOSÉ MARÍA PORRAS RAMÍREZ Anuario Iberoamericano de Justicia Constitucional, 29(1), pp. 179-203 hacen ir más allá de los límites que su propia ley orgánica dispone, se han ilustrado mediante el estudio de un interesante caso en el cual se dilucida el interés superior de una menor, en relación con los derechos que, referidos a su educación, poseen sus padres. La conclusión que se obtiene en la sentencia es harto discutible, al mostrarse como el resultado de una alteración de los hechos probados que fueron objeto de la controversia y de un sesgado juicio de ponderación que niega injustificadamente valor, al fundarse sobre nuevas premisas, al realizado por la jurisdicción ordinaria.This paper analyses a particularly controversial case that illustrates the current procedure of the Spanish Constitutional Court, according to which it considers itself competent to carry out a full review of judicial decisions in guarantee of the fundamental rights that are the object of extraordinary protection. A way of acting that makes it function as a kind of «third instance court», as can be seen especially on those occasions in which art. 24 CE is invoked, a precept that potentially enable a kind of general control of the decisions of judges and courts. In this way, the Constitutional Court interferes in questions of ordinary legality, with the pretext of adapting the legal norm to the mandates of the Constitution. The excesses in which it thus incurs, which often make it go beyond the limits that its own Organic Law establishes, have been illustrated by the study of an interesting case in which the best interest of a minor is elucidated, in relation to the rights that, regarding her education, her parents have. The conclusion reached in the Judgment is highly debatable, as it is shown to be the result of a distortion of the proven facts that were the subject of the controversy and of a biased balancing test that unjustifiably denies value, by being based on new premises, to that made by the ordinary jurisdiction

Examining Green Building Practices: The Influence on Building Information Modeling Function Diffusion
No full textThe construction sector plays a pivotal role in sustainability efforts, driving the need for innovative solutions like Building Information Modeling (BIM) to optimize green building design and performance. This study examines the diffusion of BIM functionalities that support sustainability, particularly in energy efficiency, water management, material selection, indoor environmental quality, and green building certification. Using the innovation diffusion theory, the research employs three mathematical models—internal, external, and mixed—to analyze the adoption patterns of BIM for green building applications. Empirical findings reveal that external factors, such as government regulations, financial incentives, and industry trends, significantly influence the diffusion of BIM functions related to environmental performance. The mixed diffusion model demonstrates the highest explanatory power, indicating that both external and internal drivers play a role, particularly in material selection and lifecycle assessment. This study highlights the growing integration of BIM in sustainable construction, reinforcing the need for regulatory support to accelerate adoption. These findings offer valuable insights for researchers, policymakers, and industry professionals, demonstrating how BIM can drive greener practices in the built environment. Policymakers should focus on developing policies and offering incentives such as feed-in tariffs, investment tax credits, and integrating Green BIM requirements into building codes to encourage sustainable construction practices. Also, curricula should be updated to include real-world projects and experiential learning to improve the adoption and efficiency of Green BIM practices. Future research should explore enhanced digital frameworks to further improve BIM’s impact on sustainability and lifecycle optimization

Asimismo, al Grupo de Investigación RODA de la Universidad de Santiago de Compostela.Introducción: En línea con la museología social, la Rede Museística Provincial de Lugo (RMPL) es referente de cómo convertir una institución en accesible, integradora, inclusiva, igualitaria y sostenible. Su adaptación a las necesidades sociales se manifiesta en un repertorio de experiencias formativas que trabajan la desigualdad, el territorio y la diversidad funcional. Este modelo educativo pensado para la transformación social surge y se revisa al amparo de sus XXII Xornadas Pedagóxicas. El objetivo principal es analizar estos encuentros para entender la complicidad comunitaria que la Rede ha conseguido crear en su entorno, no solo en el ámbito educativo, también con colectivos organizados.
Método: La recogida de datos comprende la información existente sobre varias ediciones de las Xornadas Pedagóxicas, y dos entrevistas con personas implicadas en su coordinación y organización. El análisis de estas fuentes permite (1) identificar las temáticas tratadas en las jornadas, (2) reflexionar en qué medida el museo ha dado respuesta a las necesidades sociales y del profesorado a través de estos encuentros, y (3) valorar las implicaciones de las jornadas para la mejora de la acción educativa entre museo y escuela.
Resultados: Desde hace más de 25 años la RMPL ha venido celebrando Xornadas Pedagóxicas dirigidas al profesorado de educación infantil, primaria y secundaria. En una primera etapa se enfocaron a dar a conocer entre el profesorado experiencias, recursos y nuevas temáticas que podían incorporarse a las aulas. A lo largo de estos años ha consolidado un largo trabajo educativo comprometido con la interseccionalidad de las desigualdades desde una concepción de museo social; situado en su contexto, capaz de involucrar a la comunidad y fortalecer el sentimiento de pertenencia.
Conclusiones: La Rede Museística Provincial de Lugo viene generando alianzas con la comunidad educativa, en las que las Xornadas Pedagóxicas son un elemento crucial para el conocimiento, innovación y transferencia de experiencias. Para ello, ha sido relevante una perspectiva abierta, de trabajo en red con otros agentes como museos de Galicia y del resto de España, universidades y colectivos sociales de diverso tipo.Introduction: In line with social museology, the Rede Museística Provincial de Lugo (RMPL) is a benchmark for how to make an institution accessible, inclusive, inclusive, egalitarian and sustainable. Its adaptation to social needs is manifested in a repertoire of educational experiences that work on inequality, territory and functional diversity. This educational model designed for social transformation arises and is reviewed under the protection of its XXII Xornadas Pedagóxicas. The main objective is to analyse these meetings in order to understand the community complicity that the Network has managed to create in its environment, not only in the educational field, but also with organised groups.
Method: The data collection includes existing information on several editions of the Pedagogical Days, and two interviews with people involved in their coordination and organisation. The analysis of these sources makes it possible to (1) identify the themes dealt with in the conferences, (2) reflect on the extent to which the museum has responded to the needs of society and teachers through these meetings, and (3) assess the implications of the conferences for the improvement of educational action between museum and school.
Results: For more than 25 years the RMPL has been holding Xornadas Pedagóxicas (Pedagogical Conferences) aimed at pre-school, primary and secondary school teachers. In the first stage, they were focused on making teachers aware of experiences, resources and new themes that could be incorporated into the classroom. Throughout these years it has consolidated a long educational work committed to the intersectionality of inequalities from a conception of social museum; situated in its context, capable of involving the community and strengthening the feeling of belonging.
Conclusions: The Rede Museística Provincial de Lugo has been generating alliances with the educational community, in which the Xornadas Pedagóxicas are a crucial element for knowledge, innovation and transfer of experiences. To this end, an open perspective has been relevant, networking with other agents such as museums in Galicia and the rest of Spain, universities and social groups of various kinds.MCIN/AEI/10.13039/501100011033, (PDC2022-133041-I00)Unión Europea NextGeneration EU/PRTRUniversidad de Santiago de Compostel
Variability analysis in memristors based on electrodeposited prussian blue
No full textThis work presents a comprehensive analysis of the variability and reliability of the resistive switching (RS) behavior in Prussian Blue (a mixed-valence iron(III/II) hexacyanoferrate compound) thin films, used as the active layer. These films are fabricated through a simple and scalable electrochemical process, and exhibit robust bipolar resistive switching, making them suitable both for neuromorphic computing applications and hardware cryptography. A detailed statistical evaluation was conducted over 100 consecutive switching cycles using multiple parameter extraction techniques to assess cycle-to-cycle (C2C) variability in key RS parameters, including set/reset voltages and corresponding currents. One and two-dimensional coefficients of variation (1DCV and 2DCV) were calculated to quantify variability and identify application potential. Results demonstrate moderate variability compatible with neuromorphic computing and cryptographic functionalities, including physical unclonable functions and true random number generation. These findings position Prussian Blue-based memristors as promising candidates for low-cost, stable, and multifunctional memory.MCIN/AEI/10.13039/501100011033 - FEDER, EU (PID2022-139586NB-C44)MCIU/AEI/10.13039/501100011033 (RYC2022–035618-I
Semi-tilling maintains the arthropod food web structure but decreases biological pest control in olive groves
No full textSemi-tilling is an extended practice in olive groves aiming to manage the water
competition between ground cover and olive trees while maintaining the soil
structure in the crop. However, the effect of semi-tilling on the arthropod community and biological pest control is still uncertain. This study assesses the impact
of semi-tilling on the arthropod community and biological pest control in olive
groves. It was approached by analysing the arthropod food web composition and
structure as well as the arthropod distribution among the three strata of the crop
(tree canopy, ground cover and epigeal soil). Stable isotope (δN15 and δC13) analysis was used to predict the trophic position of arthropods in the food web and to
establish trophic links between predators and prey. The food web structure was
measured by estimating the unweighted and node-weighted quantitative descriptors in both cases (mowing and semi-tilling). In addition, we evaluated the effect
of ground cover management on the abundance of arthropods in the three strata
of the crop. Results showed that although the structure of the food web is maintained in semi-tilled crops in summer, mowing enhances the predation pressure
on the olive grove pests Euphyllura olivina (Hemiptera: Psyllidae) and Prays oleae
(Lepidoptera: Praydidae). Thus, we observed a lower abundance of pests potentially related to the migration of predators to the olive tree canopy facilitated by
mowing. Furthermore, isotopic distances showed that Anthocoris nemoralis from
the tree and the ground cover (Hemiptera: Anthocoridae) preys on E. olivina in
the mowed olive grove, while in the semi-tilled olive grove, this trophic link disappears in the ground cover. The overall results showed that semi-tillage during late
spring–early summer negatively affects arthropod biological pest control in organic
olive groves.European Union Next Generation - Ministerio de Ciencia e Innovación (TED2021.130632B.100)Ministerio de Ciencia, Innovación y Universidades (AGL2009–09878
Influencia de la adición de la fibra de abacá en las características de los aglomerados de cemento y su comportamiento a largo plazo
No full textNatural fibers have been commonly utilized by researchers as an alternative to steel fibers
or synthetic fibers in composite materials. The use of plant-based natural fibers and
vegetable waste has garnered global attention due to their affordability, abundance, and
environmental friendliness. Among the analyzed natural fibers are coconut, sisal, jute,
hemp, and curaua; due to their wide availability, especially in tropical countries, these fibers
are cost-effective and possess the significant advantage of being renewable.
Abaca fiber is derived from the pseudostems of Musa textilis and is commonly known as
Manila hemp. In tropical countries like the Philippines, abaca plants are abundantly found,
making the country the largest global exporter, followed by Ecuador, which accounts for
15% of production. Abaca fiber is the first natural fiber to meet the quality requirements for
composites used in vehicle exteriors. Since abaca is produced in Ecuador, this fiber was
employed to determine its influence on the properties of cement composites in both shortterm
and long-term assessments. This research focused on analyzing the addition of abaca
fiber in mortars used for masonry (coating).
The research is divided into three parts:
The first part involved determining the optimal size, dosage, and treatment available for
incorporating abaca fiber into cement mortar. It was established that the mortar to be
analyzed would be the typical mixture used in Ecuador, characterized by a cement-to-sand
ratio of 1:3. In this phase, three types of fiber treatments were applied: a sodium hydroxide
solution at a concentration of 3%, silica fume combined with natural latex, and heat
treatment, utilizing fiber sizes of 20, 25, 30, and 35 mm, and dosages of 0.2%, 0.3%, and
0.4%. Thermogravimetric analysis, X-ray diffraction (XRD), scanning electron microscopy
(SEM), Fourier-transform infrared spectroscopy (FT-IR), and tensile testing were
performed on the fiber to determine the optimal performance. For the mortar, the sodium
hydroxide treatment enhanced the fiber behavior and was incorporated into the study
mortar, assessing its flexural strength and setting time.
The second part of the investigation focused on determining the short-term and long-term
mechanical behavior through accelerated aging processes of the mortar reinforced with
sodium hydroxide-treated abaca fiber, at a concentration of 3%, with a size of 30 mm and a
dosage of 0.2% by total solids weight. After 28 days, the following properties were analyzed:
dry bulk density, flexural strength, compressive strength, tensile strength, and shrinkage.
The samples underwent two types of accelerated aging through wet/dry cycles, and the
same mechanical properties were assessed, in addition to SEM and FT-IR analyses of the
treated abaca fiber post-aging.
The third part of the investigation entailed the characterization and life cycle assessment of
sodium hydroxide-treated abaca fiber, reusing the treatment solution. This segment was
developed due to the significance of sustainability and the assessment of whether the
treated plant fiber is environmentally friendly. A study was conducted on the effects of
reusing this solution analyzing abaca fibers through SEM, TGA, and tensile testing,
enhancing the inventory database and determining the carbon footprint of the treated abaca fiber in comparison with polypropylene fiber. The results indicate that reusing the treated
water is effective up to the eighth cycle, with a 25% reduction in carbon footprint, thereby
contributing to the assessment of the treatment's effectiveness and its incorporation in
masonry mortars.Las fibras naturales han sido comúnmente usadas por los investigadores como una
alternativa a las fibras de acero o fibras sintéticas en materiales compuestos. El uso de las
fibras naturales de plantas y desperdicios vegetales ha atraído la atención global debido a
su asequibilidad, abundancia y la amigabilidad con el medio ambiente. Entre las fibras
naturales que han sido analizadas se encuentran las de coco, sisal, yute, cáñamo, curaua;
debido a su amplia disponibilidad, especialmente en los países tropicales, estas fibras tienen
un costo bajo y presentan la gran ventaja de ser renovables.
La fibra de abacá se obtiene del seudo tallo de la musa textiles y se conoce comúnmente
como cáñamo de Manila. En países tropicales como Filipinas, las plantas de abacá se
encuentran en abundancia siendo el mayor exportador mundial, seguido de Ecuador con el
15% de la producción. La fibra de abacá es la primera fibra natural en cumplir con los
requerimientos de calidad para compuestos usados en los exteriores de vehículos. Debido
a que el abacá se produce en Ecuador, se utilizó esta fibra para determinar la influencia que
tendría su adición en las características de aglomerados de cemento a corto y largo plazo.
Esta investigación se enfocó en analizar la adición de la fibra de abacá en morteros usado
para albañilería (revestimiento)
La investigación está dividida en tres partes:
La primera consistió en determinar el tamaño, dosificación y tratamiento óptimo disponible
para incorporar la fibra de abacá en el mortero de cemento. Se determinó que el mortero a
analizar sería el típico trabajado en Ecuador el cual tiene una relación 1:3 cemento: arena.
En esta parte de la investigación se usaron 3 tipos de tratamientos a la fibra: solución de
hidróxido de sodio en una concentración del 3%, humo de sílice + látex natural y
hornificación, tamaños de fibra de 20-25-30 y 35mm y dosificación de 0.2-0.3 y 0.4%.
Ensayos de Termogravimetría, X-RD, SEM, FT-IR y tensión fueron realizados a la fibra para
determinar el mejor comportamiento. En cuanto al mortero, el tratamiento de hidróxido de
sodio mejoró el comportamiento de la fibra y fue adicionado al mortero de estudio,
analizando su flexotracción y tiempo de fraguado.
La segunda parte de la investigación consistió en determinar el comportamiento mecánico
a corto y largo plazo mediante procesos acelerados de envejecimiento de ese mortero
reforzado con fibra de abacá tratada con hidróxido de sodio en una concentración del 3%,
en un tamaño de 30mm y una dosificación del 0.2% del peso total de sólidos. A 28 días se
analizó: dry bulk density, flexión, compresión, tracción y shrinkage. Se sometieron las
muestras a dos tipos de envejecimiento acelerados por procesos de Wet/Dry a las mismas
propiedades mecánicas y adicional se hicieron ensayos a la fibra de abacá tratada y luego
de someterse a los procesos de envejecimiento de SEM y FT-IR.
La tercera parte de la investigación consistió en la caracterización y evaluación del ciclo de
vida de la fibra de abacá tratada con hidróxido de sodio, reusando dicha solución en el
tratamiento de la fibra. Esta parte se desarrolló por la importancia que tiene el tema de
sostenibilidad y si efectivamente la fibra vegetal tratada es amigable con el medio ambiente.
Para lo cual se hizo un estudio del efecto de reusar esta solución, analizando las fibras de abacá mediante SEM, TGA, tracción, se aumentó la base de dato de inventario y se determinó
la huella de carbono de la fibra de abacá tratada comparándola con fibra de polipropileno.
Los resultados muestran que reusar el agua tratada es efectiva hasta el octavo ciclo, en
términos de huella de carbono se reduce a un 25%, con lo cual esta investigación aporta
hasta el ciclo de efectividad del tratamiento y su incorporación en morteros de albañilería.Tesis Univ. Granada

Power and Attraction of the Desert. Geocultures of France and Spain Facing Tribal Insubordination in the Sahara (1900-1934)
No full textEl debate sobre la cuestión colonial en relación con los inacabados procesos de descolonización en el Sáhara Occidental tiene una gran actualidad. Para interpretarlos es necesario recurrir a las estrategias seguidas por Francia y España para someter el sistema tribal y las redes morabíticas saharianas. Desde el estudio de las teorías segmentaristas tribales hasta la mística del desierto. Los informes confidenciales franceses ofrecen noticias importantes para interpretar la geomística empleada en la conquista y sumisión del Sáhara. Todo como parte del gran juego geoestratégico sahariano. Figuras como Charles de Foucauld, Ernest Psichari o Enrique D’Almonte son fundamentales para la correcta interpretación de las políticas de dominación.The debate on the colonial question in relation to the unfinished processes of decolonization in Western Sahara is highly topical. In order to interpret them it is necessary to resort to the strategies followed by France and Spain to subdue the tribal system and the Saharan morabitic networks. From the study of tribal segmentationist theories to the mystique of the desert. The French confidential reports offer important news to interpret the geomistics used in the conquest and submission of the Sahara. All as part of the great Saharan geostrategic game. Figures such as Charles de Foucauld, Ernest Psichari or Enrique D'Almonte are fundamental for the correct interpretation of the politics of domination
