La gamificació a prova. Implantació i estudi dels resultats obtinguts de la gamificació versus les metodologies tradicionals

Funciona realment la gamificació? Millora l'aprenentatge? És realment la solució al ensenyament actual? Aquest TFM mostra a petita escala el funcionament de l'aplicació pràctica de la gamificació en l'aprenentatge. Per això, s'ha aplicat el mateix temari d'una unitat didàctica a dues classes amb resultats similars de segon d'ESO, en una d'elles gamificada i en l'altre aplicant una metodologia més tradicional. Posteriorment s'han avaluat els resultats obtinguts per tal d'arribar a una conclusió real de com afecta la gamificació en l'aprenentatge

Celler Can Calopa de Dalt

El Celler de Can Calopa de Dalt és un equipament públic pertanyent al districte de Sarrià-Sant Gervasi i propietat i administrat per l’Ajuntament de Barcelona destinat a l’elaboració de vi amb denominació d’origen de Barcelona i amb una sèrie de dependències destinades per activitats del món enològic (conferències, recerca, cursos,.....). El Nou Celler de Can Calopa es genera a partir del concepte de fusió entre naturalesa i home i del pensament de què són dos elements inseparables. Així, els elements naturals permeten donar riquesa als espais creats per un fi determinat. La realitat d’aquests pensaments s’han materialitzat atorgant una presència contínua, però regulada, de la lluminositat i de les vistes que ofereix el lloc on es situa el projecte: el parc natural de Collserola. Són els sentiments i sensacions els que identifiquen i determinen els espais, és més, són els que els organitzen, els vesteixen amb materials i finalment els hi donen un caràcter propi

Test anxiety, coping strategies and self-efficacy in university students

Treball Final de Grau en Psicologia. Codi: PS1048. Curs: 2020/2021The university students face situations that require a lot of effort in order to overcome each course and achieve a good academic performance. However, when students experience these situations as negative events, the situations become obstacles and it influences their academic performance negatively. One of the most common situations is taking an exam, which requires prior preparation and the maintenance of concentration during the exam, which can lead to test anxiety. In addition, the type of coping strategy chosen and the student's level of self-efficacy will influence the student’s ability to cope with the exam situation. Due to the fact that these variables influence academic performance, there is a need to study them and see their relationship. The objective of this study is to analyze the importance of the relationship between the variables of test anxiety, coping strategies and self-efficacy in the first year university students of Bachelor’s Degree in Criminology and Security of the UJI. Through the Qualtrics platform, the German Test Anxiety Inventory (GTAI-AR) and the Coping Scale of the Academic Stress Questionnaire (A-CEA) and Baessler and Schwarzer General Self-Efficacy Scale, were administered to 58 female university students. The results showed that there is a positive relationship between test anxiety and coping strategies, a negative relationship between test anxiety and self-efficacy and a positive relationship between coping strategies and self-efficacy. We consider that the level of test anxiety of test anxiety is associated with the utilization of diferent coping strategies in exam situations and to the level of self-efficacy experienced. Finally, the level of self-efficacy is associated with coping strategies used to cope with the exam.Los estudiantes universitarios se enfrentan a situaciones que requieren mucho esfuerzo y son necesarias para poder superar cada curso y conseguir un buen rendimiento académico. Sin embargo, cuando los estudiantes experimentan estas situaciones como sucesos negativos, éstas se convierten en obstáculos e influyen negativamente en su rendimiento académico. Una de las más comunes es la de realizar un examen, el cual requiere de una preparación previa y del mantenimiento de la concentración durante el mismo, lo que puede provocar ansiedad académica. Además, el tipo de estrategia de afrontamiento elegida y el nivel de autoeficacia, van a influir en la capacidad del estudiante para realizar el examen. Debido a que estas variables influyen en el rendimiento académico, se encuentra la necesidad de estudiarlas y ver cuál es la relación que hay entre ellas. El objetivo del presente estudio es analizar la importancia de la relación entre las variables ansiedad académica, estrategias de afrontamiento y autoeficacia en estudiantes universitarios de primer curso del Grado en Criminología y Seguridad de la UJI.

Retrieval of eddy dynamics from SMOS sea surface salinity measurements in the Algerian Basin (Mediterranean Sea)

8 pages, 4 figures, supporting information https://dx.doi.org/10.1002/2016GL069595The circulation in the Algerian Basin is characterized by the presence of fresh-core eddies that propagate along the coast or at distances between 100 and 200 km from the coast. Enhancements in the processing of the Soil Moisture and Ocean Salinity (SMOS) data have allowed to produce, for the first time, satellite sea surface salinity (SSS) maps in the Mediterranean Sea that capture the signature of Algerian eddies. SMOS data can be used to track them for long periods of time, especially during winter. SMOS SSS maps are well correlated with in situ measurements although the former has a smaller dynamical range. Despite this limitation, SMOS SSS maps capture the key dynamics of Algerian eddies allowing to retrieve velocities from SSS with the correct sign of vorticityThis work has been funded by the Spanish Ministry of Economy through the National R+D Plan by means of Promises project (ESP2015-67549-C3) and previous grants and by the European Space Agency through the GlobCurrent Data User Element project (4000109513/13/I-LG).

A surface-aware projection basis for quasigeostrophic flow

Recent studies indicate that altimetric observations of the ocean's mesoscale eddy field reflect the combined influence of surface buoyancy and interior potential vorticity anomalies. The former have a surface-trapped structure, while the latter have a more grave form. To assess the relative importance of each contribution to the signal, it is useful to project the observed field onto a set of modes that separates their influence in a natural way. However, the surface-trapped dynamics are not well-represented by standard baroclinic modes; moreover, they are dependent on horizontal scale. Here we derive a modal decomposition that results from the simultaneous diagonalization of the energy and a generalisation of potential enstrophy that includes contributions from the surface buoyancy fields. This approach yields a family of orthonomal bases that depend on two parameters: the standard baroclinic modes are recovered in a limiting case, while other choices provide modes that represent surface and interior dynamics in an efficient way. For constant stratification, these modes consist of symmetric and antisymmetric exponential modes that capture the surface dynamics, and a series of oscillating modes that represent the interior dynamics. Motivated by the ocean, where shears are concentrated near the upper surface, we also consider the special case of a quiescent lower surface. In this case, the interior modes are independent of wavenumber, and there is a single exponential surface mode that replaces the barotropic mode. We demonstrate the use and effectiveness of these modes by projecting the energy in a set of simulations of baroclinic turbulence

The GDNF-GFRα1 complex promotes the development of hippocampal dendritic arbors and spines via NCAM

The formation of synaptic connections during nervous system development requires the precise control of dendrite growth and synapse formation. Although glial cell line-derived neurotrophic factor (GDNF) and its receptor GFRα1 are expressed in the forebrain, the role of this system in the hippocampus remains unclear. Here, we investigated the consequences of GFRα1 deficiency for the development of hippocampal connections. Analysis of conditional Gfra1 knockout mice shows a reduction in dendritic length and complexity, as well as a decrease in postsynaptic density specializations and in the synaptic localization of postsynaptic proteins in hippocampal neurons. Gain- and loss-of-function assays demonstrate that the GDNF-GFRα1 complex promotes dendritic growth and postsynaptic differentiation in cultured hippocampal neurons. Finally, in vitro assays revealed that GDNF-GFRα1- induced dendrite growth and spine formation are mediated by NCAM signaling. Taken together, our results indicate that the GDNF-GFRα1 complex is essential for proper hippocampal circuit development.Fil: Irala, Dolores.

Innovative calibration method for rotating-coil magnetometers

Rotating-coil magnetometers, which rely on induction-coil arrays, are commonly used for magnetic measurements of particle accelerator magnets. In order to characterize magnetic fields with high accuracy using the induced voltages, it is essential to calibrate the geometry of the coils. In this thesis we present an innovative method of calibration of the coil radius of rotation which is necessary for determination of the field gradient. The method, called rotating calibration method, is based on two well-known measurement techniques: single-stretched wire and rotating induction-coils. The flux measured with a rotating induction-coil over the entire length of a reference quadrupole magnet is cross-calibrated with a single-stretched wire measurement. In the experimental validation of the method, the radius of rotation of several coils has been calibrated with an accuracy of 10 µm on a radius of 30 mm. The advantage of this method is that the calibration is performed under the same conditions in which the rotating-coil magnetometers are used for measuring accelerator magnets. In the thesis also a proposal for calibration of other geometric factors of a coil by using higher order multipoles is presented
