Digital creativity to transform learning: Empowerment from a com-educational approach

Daily media use by an entire generation shows the distance that exists between the reality experienced by young people and the institutions responsible for their education. Formal education is still closely linked to the passive role of literary receivers, ignoring the potential of connected communication for student empowerment. At the same time, there is a growing interest in education from the professional media field. We have called this line of force the com-educational vector. In this study, we aim to describe the potential of a com-educational perspective to favor the empowerment of young people. The implemented methodology combines a chained articulation involving the analysis of multimodal discourse of com-educational platforms with interviews with privileged observers. The results show that the implementation of digital creation can be used for the construction of identity, interaction and socialization of students through emotion, empathy and the capacity for transformation. It enables the establishment of nodes between concepts, relational understanding, meaningful reconstruction and appropriation. It is concluded that, under this proposal, formal education institutions could move from a reactive model to a prospective model, revising the codes of emission and reception, and proposing meanings from creative action and feedback with the community. Los usos mediáticos cotidianos de toda una generación evidencian la distancia que existe entre la realidad que vive la juventud y las instituciones responsables de su formación. La educación formal sigue estrechamente vinculada al rol pasivo de los receptores literarios, obviándose el potencial de la comunicación conectada y la narrativa digital para el empoderamiento del alumnado. Al mismo tiempo, se está produciendo un interés creciente desde el ámbito mediático profesional por la educación. A esta línea de fuerza la hemos denominado vector com-educativo. En esta investigación, tenemos como objetivo describir potencialidades para favorecer el empoderamiento de los jóvenes desde una perspectiva com-educativa. La metodología implementada combina, en una articulación encadenada, el análisis del discurso multimodal de plataformas de carácter com-educativo con entrevistas a observadores privilegiados. En los resultados se explicita que la implementación de la creación digital se puede emplear para la construcción de la identidad, la interacción y la sociabilización del alumnado a través de la emoción, la empatía y la capacidad de transformación. Permite establecer nodos entre conceptos, la comprensión relacional, la reconstrucción significativa y su apropiación. Se concluye que, bajo esta propuesta, las instituciones de educación formal podrían transitar de un modelo reactivo a un modelo prospectivo, revisando los códigos de emisión y recepción, y proponiendo significados desde la acción creativa y la retroalimentación con la comunidad.

Diagnostic Relations between Pressure and Entropy Perturbations for Acoustic and Entropy Modes

Diagnostics and decomposition of atmospheric disturbances in a planar flow are considered and applied to numerical modelling with the direct possibility to use in atmosphere monitoring especially in such strong events which follow magnetic storms and other large scale atmospheric phenomena. The study examines a situation in which the stationary equilibrium temperature of a gas may depend on a vertical coordinate, which essentially complicates the diagnostics. The relations connecting perturbations for acoustic and entropy (stationary) modes are analytically established and led to the solvable diagnostic equations. These equations specify acoustic and entropy modes in an arbitrary stratified gas under the condition of stability. The diagnostic relations are independent of time and specify the acoustic and the entropy modes. They provide the ability to decompose the total vector of perturbations into acoustic and non-acoustic (entropy) parts uniquely at any instant within the total accessible heights range. As a prospective model, we consider the diagnostics at the height interval 120–180 km, where the equilibrium temperature of a gas depends linearly on the vertical coordinate. For such a heights range it is possible to proceed with analytical expressions for pressure and entropy perturbations of gas variables. Individual profiles of acoustic and entropy parts for some data are illustrated by the plots for the pure numerical data against those obtained by the model. The total energy of a flow is determined for both approaches and its vertical profiles are compared.

Cu and Cu-SWCNT Nanoparticles’ Suspension in Pulsatile Casson Fluid Flow via Darcy–Forchheimer Porous Channel with Compliant Walls: A Prospective Model for Blood Flow in Stenosed Arteries

The use of experimental relations to approximate the efficient thermophysical properties of a nanofluid (NF) with Cu nanoparticles (NPs) and hybrid nanofluid (HNF) with Cu-SWCNT NPs and subsequently model the two-dimensional pulsatile Casson fluid flow under the impact of the magnetic field and thermal radiation is a novelty of the current study. Heat and mass transfer analysis of the pulsatile flow of non-Newtonian Casson HNF via a Darcy–Forchheimer porous channel with compliant walls is presented. Such a problem offers a prospective model to study the blood flow via stenosed arteries. A finite-difference flow solver is used to numerically solve the system obtained using the vorticity stream function formulation on the time-dependent governing equations. The behavior of Cu-based NF and Cu-SWCNT-based HNF on the wall shear stress (WSS), velocity, temperature, and concentration profiles are analyzed graphically. The influence of the Casson parameter, radiation parameter, Hartmann number, Darcy number, Soret number, Reynolds number, Strouhal number, and Peclet number on the flow profiles are analyzed. Furthermore, the influence of the flow parameters on the non-dimensional numbers such as the skin friction coefficient, Nusselt number, and Sherwood number is also discussed. These quantities escalate as the Reynolds number is enhanced and reduce by escalating the porosity parameter. The Peclet number shows a high impact on the microorganism’s density in a blood NF. The HNF has been shown to have superior thermal properties to the traditional one. These results could help in devising hydraulic treatments for blood flow in highly stenosed arteries, biomechanical system design, and industrial plants in which flow pulsation is essential.

Diagnostic Relations Between Pressure and Entropy Perturbations for Acoustic and Entropy Modes

Diagnostics and decomposition of atmospheric disturbances in a planar flow are considered and applied to numerical modeling results with the direct possibility to use in atmosphere monitoring especially in such strong events which follow magnetic storms. The study examines a situation in which the stationary equilibrium temperature of a gas may depend on a vertical coordinate, that seriously complicates the problem solution. The relations connecting perturbations for acoustic and entropy modes are analytically established and led to the solvable diagnostic equations. These perturbation structures, found as the equation solutions specify acoustic and entropy modes in an arbitrary stratified gas under the condition of stability. These time-independent diagnostic relations link gas perturbation variables of the acoustic and the entropy modes. Hence, they provide the ability to decompose the total vector of perturbations into acoustic and non-acoustic (entropy) parts uniquely at any instant within the all accessible heights range. As a prospective model, we consider the diagnostics at the height interval [120;180] km, where the equilibrium temperature of a gas depends linearly on the vertical coordinate. For such a heights range it is possible to proceed with analytical expressions for pressure and entropy perturbations of gas variables. Individual profiles of acoustic and entropy parts for some data, obtained by numerical experiment, are illustrated by the plots for the pure numerical data against ones obtained by the model. The total energy of a flow is determined for both approaches and its height profiles are compared.

What Factors Help Young Children Develop Positive Perceptions of Their Motor Skills?

A positive perception of motor skills is important for physical activity participation. The aim was to investigate which modifiable factors predict children’s perceived motor skills. Mothers completed questionnaires when their child was 3.5 and 5 years old. At 5 years old, the children’s perceived motor competence (PMC) was assessed. Separate linear regression models (up to 300 children) examined which factors at each time point predicted children’s PMC, adjusted for relevant confounders. Multivariate models were then run with factors associated (p < 0.10) with perception. At 3.5 years, the time spent with same age and older children (both higher tertiles) and parental physical activity facilitation (sum of facilitation in last month, e.g., taking child to park) were initially associated with higher perception. Dance/gymnastics participation were associated with lower perceptions. Other child behaviours, maternal beliefs, play equipment, and swimming lessons were non-significant. In the final prospective model (n = 226), parental physical activity facilitation when child was 3.5 years old was the only factor to predict PMC. No factors were significant for the cross-sectional analyses at 5 years. Perceptions are formed based on past experiences which may explain why factors at 3.5 years rather than current experiences (when children were 5 years old) were associated with childhood perceptions.
