Analizando patrimonio y participación en el Barrio Gótico de Barcelona: Algunos apuntes metodológicos

Throughout this work, we will explore different methodologies applied for the study of the relation ship between the archaeological heritage located in public space, and the social fabric of the Gothic Quarter in Barcelona. The presence of archaeological elements confers a dialogue between the ruins and the quarter’s inhabitants that different agents can use at different times. This study explores avenues to know and establish new dialogues, that value not only the cultural good in itself, but also all of its spatial context. We expose a series of ethnographic techniques and analyse the use of them in different situations. This work is framed in a political moment wherein privileged participative practices in an incipient institutionalisation of participation is understood as a tool of social empowerment.A lo largo de este trabajo vamos a explorar distintas metodologías que hemos aplicado para el estudio de la relación del patrimonio arqueológico ubicado en el espacio público y el tejido social del Barrio Gótico de Barcelona. La presencia de elementos arqueológicos confiere un diálogo ruina-habitante que distintos agentes pueden utilizar en distintos momentos. Este estudio explora la forma de conocer y establecer nuevos diálogos que valoricen no solo el bien cultural en sí mismo, sino todo su contexto espacial. Para ello expondremos una serie de técnicas etnográficas y analizaremos el uso de las mismas en distintas situaciones. Este se contextualiza en un momento marcado por la llegada al poder de los partidos de abajo, y una incipiente institucionalización de la participación entendida como herramienta de empoderamiento social

Zeros of irreducible characters in factorised groups

[EN] An element g of a finite group G is said to be vanishing inG if there exists an irreducible character of G such that (g)=0; in this case, g is also called a zero of G. The aim of this paper is to obtain structural properties of a factorised group G=AB when we impose some conditions on prime power order elements gAB which are (non-)vanishing in G.The first author is supported by Proyecto PrometeoII/2015/011, Generalitat Valenciana (Spain).

La participación como tarea de lo cotidiano: el barrio Gòtic de Barcelona

Las calles del barrio Gòtic de Barcelona poseen un carácter bullicioso. Allí los miles de turistas se mezclan con algunos funcionarios, prelados, comerciantes, paseantes y, en menor medida, vecinos. Recientemente el investigador Agustín Cócola Gant dio a conocer al gran público su 'imagen de marca' o 'invento' a través de una cuidada publicación, acompañada de otros estudios sobre la turistificación del mismo (CÓCOLA GANT, 2011; 2014). En el corazón de la Ciutat Vella de Barcelona, este lugar se acota entre espacios icónicos como la plaza Cataluña, el paseo Colón, la vía Layetana y las literarias Ramblas -una autopista de peatones que circulan en ambos sentidos, a cualquier hora del día y la noche-. Uno de los barrios con más 'pisos turísticos' de toda la ciudad -legales e ilegales-, donde los alquileres desaparecieron dejando paso a situaciones más lucrativas para sus dueños, como Airbnb. Es en este caldo de cultivo donde han nacido una serie de movimientos, que basándose en el activismo y la participación ciudadana buscan, a veces sin mencionarlo explícitamente, recuperar el patrimonio cultural que queda fuera del discurso autorizado: la calle, las plazas, los espacios relacionales públicos..., lo cotidiano

Les emocions a l’Educació Infantil Detecció de necessitats

Dissetenes Jornades de Foment de la Investigació de la FCHS (Any 2012)Aquesta investigació tracta de les emocions en l’Educació Infantil. El que es pretén és comprovar si el treball de les emocions és suficient i adequat a les escoles, així com demostrar la importància d’aquestes. Per això, hem dissenyat un qüestionari dirigit al professorat que consta de dues parts (una personal i l’altra professional), i que ens dóna informació sobre com treballen les seues pròpies emocions i com les treballen amb l’alumnat dintre de l’aula. Aquest es va passar a una mostra composada per tres mestres d’Educació Infantil d’un centre públic de la província de Castelló. Els resultats obtinguts van afirmar la necessitat del treball emocional a les aules, tot i que també es va demostrar l’interès de les docents sobre el tema. A partir d’aquests resultats, es va dissenyar un projecte d’innovació educativa per a intervenir en el treball de les emocions, tant dintre de l’aula amb l’alumnat, com amb les famílies i amb el professorat

Mechanism and Consequences of The Impaired Hif-1α Response to Hypoxia in Human Proximal Tubular HK-2 Cells Exposed to High Glucose

Renal hypoxia and loss of proximal tubular cells (PTC) are relevant in diabetic nephropathy. Hypoxia inhibits hypoxia-inducible factor-1α (HIF-1α) degradation, which leads to cellular adaptive responses through HIF-1-dependent activation of gene hypoxia-responsive elements (HRE). However, the diabetic microenvironment represses the HIF-1/HRE response in PTC. Here we studied the mechanism and consequences of impaired HIF-1α regulation in human proximal tubular HK-2 cells incubated in hyperglycemia. Inhibition at diferent levels of the canonical pathway of HIF-1α degradation did not activate the HIF-1/HRE response under hyperglycemia, except when proteasome was inhibited. Further studies suggested that hyperglycemia disrupts the interaction of HIF-1α with Hsp90, a known cause of proteasomal degradation of HIF-1α. Impaired HIF-1α regulation in cells exposed to hyperglycemic, hypoxic diabetic-like milieu led to diminished production of vascular endothelial growth factor-A and inhibition of cell migration (responses respectively involved in tubular protection and repair). These efects, as well as impaired HIF-1α regulation, were reproduced in normoglycemia in HK-2 cells incubated with microparticles released by HK-2 cells exposed to diabetic-like milieu. In summary, these results highlight the role of proteasome-dependent mechanisms of HIF-1α degradation on diabetesinduced HK-2 cells dysfunction and suggest that cell-derived microparticles may mediate negative efects of the diabetic milieu on PTCThis work was supported by grants SAF2014-53218-R from the Spanish Ministerio de Ciencia e Innovación and RTI2018-095872-B-C21/ERDF by AEI.
