Aproximación del arte de acción a la Educación Infantil. Otras formas de interrelación en el contexto educativo

This Artistic research project was created in order to test how to put into practice approaches between Contemporary Art and University daily life. In this particular case, between Action Art and the students at the Early Childhood Education University in Alicante. The generalized lack of awareness about changes which took place in Art in the XX century, demonstrates the lack of interest on the part of students about Contemporary Art, and therefore, it is still remarkable, the distance between Art and life. Thus, as artists and teachers, the chance to carry out specific experiments is open within everyday educational life. Therefore, through Action Art a communicative interaction is possible to be achieved as an active learning process and, in such way, change the usual existing relationships in a predetermine context, creating this way, future Contemporary Art consumers and transmitters.Este trabajo de investigación artística, se crea con el propósito de experimentar sobre cómo llevar a la práctica aproximaciones entre el arte contemporáneo y la vida cotidiana universitaria. En este caso, más concretamente, entre el arte de acción y el alumnado de Educación Infantil de la Facultad de Educación de Alicante. El desconocimiento generalizado sobre los cambios acontecidos en el arte durante el siglo XX, evidencia la falta de interés del alumnado sobre el arte contemporáneo, y por consiguiente, sigue estando vigente, la separación entre arte y vida. Por ello, como artistas y docentes, abrimos la posibilidad de realizar experimentos concretos dentro de la vida cotidiana educativa, para que a través del arte de acción, se llegue a una interacción comunicativa como proceso activo de aprendizaje, y así, cambiar las relaciones habituales que se tienen en un contexto determinado, con el otro y consigo mismo, generando futuros consumidores y transmisores de arte contemporáneo

Topological Traps Control Flow on Real Networks: The Case of Coordination Failures

We study evolutionary games in real social networks, with a focus on coordination games. We find that populations fail to coordinate in the same behavior for a wide range of parameters, a novel phenomenon not observed in most artificial model networks. We show that this result arises from the relevance of correlations beyond the first neighborhood, in particular from topological traps formed by links between nodes of different degrees in regions with few or no redundant paths. This specificity of real networks has not been modeled so far with synthetic networks. We thus conclude that model networks must be improved to include these mesoscopic structures, in order to successfully address issues such as the emergence of cooperation in real societies. We finally show that topological traps are a very generic phenomenon that may arise in very many different networks and fields, such as opinion models, spread of diseases or ecological networks

Mesoscopic structure conditions the emergence of cooperation on social networks

We study the evolutionary Prisoner's Dilemma on two social networks obtained from actual relational data. We find very different cooperation levels on each of them that can not be easily understood in terms of global statistical properties of both networks. We claim that the result can be understood at the mesoscopic scale, by studying the community structure of the networks. We explain the dependence of the cooperation level on the temptation parameter in terms of the internal structure of the communities and their interconnections. We then test our results on community-structured, specifically designed artificial networks, finding perfect agreement with the observations in the real networks. Our results support the conclusion that studies of evolutionary games on model networks and their interpretation in terms of global properties may not be sufficient to study specific, real social systems. In addition, the community perspective may be helpful to interpret the origin and behavior of existing networks as well as to design structures that show resilient cooperative behavior.Comment: Largely improved version, includes an artificial network model that fully confirms the explanation of the results in terms of inter- and intra-community structur

Generation of mitochondrial reactive oxygen species is controlled by ATPase inhibitory factor 1 and regulates cognition.

The mitochondrial ATP synthase emerges as key hub of cellular functions controlling the production of ATP, cellular signaling, and fate. It is regulated by the ATPase inhibitory factor 1 (IF1), which is highly abundant in neurons. Herein, we ablated or overexpressed IF1 in mouse neurons to show that IF1 dose defines the fraction of active/inactive enzyme in vivo, thereby controlling mitochondrial function and the production of mitochondrial reactive oxygen species (mtROS). Transcriptomic, proteomic, and metabolomic analyses indicate that IF1 dose regulates mitochondrial metabolism, synaptic function, and cognition. Ablation of IF1 impairs memory, whereas synaptic transmission and learning are enhanced by IF1 overexpression. Mechanistically, quenching the IF1-mediated increase in mtROS production in mice overexpressing IF1 reduces the increased synaptic transmission and obliterates the learning advantage afforded by the higher IF1 content. Overall, IF1 plays a key role in neuronal function by regulating the fraction of ATP synthase responsible for mitohormetic mtROS signaling

From Boolean Equalities to Constraints

Although functional as well as logic languages use equality to discriminate between logically different cases, the operational meaning of equality is different in such languages. Functional languages reduce equational expressions to their Boolean values, True or False, logic languages use unification to check the validity only and fail otherwise. Consequently, the language Curry, which amalgamates functional and logic programming features, offers two kinds of equational expressions so that the programmer has to distinguish between these uses. We show that this distinction can be avoided by providing an analysis and transformation method that automatically selects the appropriate operation. Without this distinction in source programs, the language design can be simplified and the execution of programs can be optimized. As a consequence, we show that one kind of equational expressions is sufficient and unification is nothing else than an optimization of Boolean equality

Efecto agudo de ejercicio isométrico sobre parámetros autonómicos en adultos sedentarios obesos y con sobrepeso

Introduction: Obesity is understood as a chronic inflammation associated with complications in the autonomic nervous system dysfunction related to cardiovascular diseases. And isometric exercise, represented by manual grip strength, favors the reduction of cardiovascular risk and autonomic imbalance. Objective: to describe the acute response of an isometric exercise (IE) compared to the effect of an aerobic exercise (AE), analyzing the autonomic parameters of heart rate variability (LF/HF), diastolic blood pressure (DBP), systolic blood pressure (SBP) and heart rate (HR) in obese and overweight people. Methodology: 20 participants were randomly distributed into 2 groups; those who performed an aerobic exercise session on a cycle ergometer for 15 min at 50 watts (n=10) and those who performed an IE session at 30% of maximal strength (n=10). Both were evaluated pre and post intervention, the variables were analyzed using the Mann-Whitney U statistical test with a significance level of p<0.05. Results: IE produced statistically significant changes in SBP (p= 0.001), LH/HF (p=0.02) and HR (p=0.018), while DBP improved, but not significantly. Conclusions: an EI session generates a greater decrease than EA in HRV, HR and SBP variables.Introducción: La obesidad es entendida como una inflamación crónica asociada a complicaciones en la disfunción del sistema nervioso autónomo relacionada con enfermedades cardiovasculares. Y el ejercicio isométrico, representado por la fuerza de prensión manual, favorece la reducción del riesgo cardiovascular y al desequilibrio autonómico. Objetivo: describir la respuesta aguda de un ejercicio isométrico (EI) comparándolo con el efecto de un ejercicio aeróbico (EA), analizando los parámetros autonómicos de variabilidad de la frecuencia cardiaca (LF/HF), presión arterial diastólica (PAD), sistólica (PAS) y la frecuencia cardiaca (FC) en personas obesos y en sobrepeso. Metodología: 20 participantes fueron distribuidos al azar en 2 grupos; los que realizaron una sesión de ejercicio aeróbico en cicloergómetro durante 15 min a 50 watts (n=10) y los que realizaron una sesión de EI al 30% de la fuerza máxima. Ambos fueron evaluados pre y post intervención, se analizaron las variables mediante la prueba estadística U de Mann-Whitney con un nivel de significancia p<0,05. Resultados: El EI produjo cambios estadísticamente significativos en PAS (p= 0,001), LH/HF (p = 0,02) y FC (p=0,01), mientras que la PAD mejoró, pero no de forma significativa. Conclusiones: una sesión de EI, genera una mayor disminución que el EA en las variables de VFC, FC y PAS

100 myr cycles of oceanic lithosphere generation in peri-Gondwana: Neoproterozoic–Devonian ophiolites from the NW African–Iberian margin of Gondwana and the Variscan Orogen

The datasets generated during and/or analysed during the current study are availablein the DIGITAL.CSIC repository: http://doi.org/10.20350/digitalCSIC/12510.[EN] The Variscan Orogen in Iberia and the Anti-Atlas Mountains in Morocco contains a set of ophiolites formed between Neoproterozoic and Devonian times, during the complex evolution of the NW African–Iberian margin of Gondwana. During this time interval, the margin evolved from an active margin (c. 750–500 Ma: the Reguibat–Avalonian–Cadomian arc) to the final collision with Laurussia in Devonian times to form Pangaea. In this context, one of the oldest recognized ophiolites is the Bou Azzer Ophiolite from the Anti-Atlas Mountains, dated at c. 697 Ma and containing two types of mafic rocks, the youngest of which has a boninitic composition. To the north, in the SW Iberian Massif, the Calzadilla Ophiolite contains mafic rocks also of boninitic composition dated at c. 598 Ma. Farther north, in the NW Iberian Massif, the Vila de Cruces Ophiolite is formed by a thick sequence of mafic rocks with an arc tholeiitic composition and minor alternations of tonalitic orthogneisses dated at c. 497 Ma. In the same region, the Bazar Ophiolite has a similar age of c. 495 Ma. Also in NW Iberia, there is a group of ophiolites with varied lithologies and dominant mafic rocks with arc tholeiitic composition (Careón, Purrido and Moeche ophiolites) dated at c. 395 Ma. The composition of all these peri-Gondwanan ophiolites is of supra-subduction zone type, showing no evidence of preserved mid-ocean ridge basalt type oceanic lithosphere. Consequently, these ophiolites were generated in the peri-Gondwanan realm during the opening of forearc or back-arc basins. Forearc oceanic lithosphere was promptly obducted or accreted to the volcanic arc, but the oceanic or transitional lithosphere generated in back-arc settings was preserved until the assembly of Pangaea. Based on the ages of the described ophiolites, the peri-Gondwanan realm has been a domain where the generation of oceanic or transitional lithosphere seems to have occurred at intervals of c. 100 myr. These regularly spaced time intervals may indicate cyclic events of mantle upwelling in the peri-Gondwanan mid-ocean ridges, with associated higher subduction rates at the peri-Gondwanan trenches and concomitant higher rates of partial melting in the mantle wedges involved. The origin of the apparent cyclicity for mantle upwelling in the peri-Gondwanan ocean ridges is unclear, but it could have possibly been related to episodic deep mantle convection. Cycles of more active deep mantle convection can explain episodic mantle upwelling, the transition from low- to fast-spreading type mid-ocean ridges and, finally, the dynamic context for the episodic generation of new supra-subduction zone type oceanic peri-Gondwanan lithosphere.Financial support has been provided bySpanish projects CGL2016-76438-P and CGL2015-65824 (Ministerio de Economía, Industria y Competitividad) anda FPU grant to Núria Pujol-Solà (Ministerio de Educación)Peer reviewe
