  • Laura Osorio-Planes
  • Miquel A. Pericàs
<p> The widely applicable TRIP phosphoric acid catalyst has been immobilized on polystyrene using a copolymerization-based strategy. The resin (<strong>PS-TRIP</strong>) has proven to be highly active and enantioselective in the asymmetric allylboration of aldehydes. Moreover, it has shown to be extremely robust, as it can be reused for 18 times, after which it still retained its activity. Lastly, to further prove the benefits of the immobilization, a continuous flow experiment spanning 28 h has been carried out with very high yields and ee&rsquo;s.</p> <p> &nbsp;</p>

La investigación formativa como metodología de aprendizaje en la mejora de competencias transversales

  • Rubio Hurtado, María José
  • Vilà Baños, Ruth
  • Berlanga, Vanessa,
En una asignatura del grado de Pedagogía de la Universidad de Barcelona se ha aplicado una metodología de Aprendizaje Orientada a Proyectos (AOP) y un portafolio digital, como estrategias para la investigación formativa en la que el alumnado es protagonista activo de su propio proceso de aprendizaje. Los resultados, desde la perspectiva del alumnado participante, destacan especialmente el desarrollo de dos competencias básicas como son el trabajo colaborativo y la capacidad de reflexión., In a class degree in Education at University of Barcelona has applied a methodology of Learning Based Projects (PBL) and digital portfolio, as strategies for “research training” in which the student is an active protagonist in their own learning process. The results, from the perspective of students participating, include especially the development of two basic skills such as collaborative work and the ability to reflect.

La empleabilidad es uno de los factores angulares en las políticas públicas universitarias. De hecho, es habitual que las instituciones públicas intenten adaptar la oferta de Educación Superior a la demanda real del mercado de trabajo. En este sentido, es fundamental parametrizar los factores de interés de los estudiantes a la hora de desarrollar sus preferencias hacia las universidades. En esta investigación analizamos los factores que condicionan a los futuros universitarios cuando tratan de elegir centro de enseñanza superior. Se realizó un estudio cuantitativo clusterizando factores de importancia, desde un enfoque econométrico y factorial. Se concluye que el sexo, el tipo de centro de Secundaria de procedencia y el nivel socioeconómico son factores determinantes de elección. Ello es clave como herramienta para la previsión de empleabilidad y de mejora a la hora de proporcionar a los estudiantes, los centros universitarios y las administraciones públicas., Employability is one of the angular factors in university public policies. In fact, it is common for public institutions trying to adapt the supply of Superior Education to actual demand of the labor market. In this regard, it is essential to parameterize the factors of interest to students in developing their preferences for universities. In this research we analyze the factors that affect future students when trying to choose higher education. It has carried out a quantitative study of important factors thanks to clusterization, from econometric and factorial approach. It is concluded that sex, type of secondary school of origin and socioeconomic factors are determinants of choice. This is essential as a tool for predicting and improving employability when providing students, academia and government.

The influence of psychosocial factors on human behaviour in emergency

  • Saccinto, Elisa
  • Pérez Testor, Carles

Lo scopo di questo studio e ` esplorare l’effetto di alcuni fattori psicosociali sul comportamento umano durante una situazione d’emergenza. In accordo con le osservazioni della teoria dell’Attaccamento Sociale nei disastri (Mawson 2005, 2007), le persone che si trovano in pericolo sperimentano sentimenti di attaccamento verso persone o luoghi familiari. Questi sentimenti hanno un effetto rassicurante, riducendo o ritardando i comportamenti di evacuazione. I partecipanti allo studio sono 173 superstiti di diverse situazioni d’emergenza, tra questi 42.4% sono uomini e 57.6% donne con un’eta ` media di 32.52 anni (DS 13.68). I risultati hanno evidenziato un’associazione negativa tra l’essere con persone familiari e il ritardo nel cominciare l’evacuazione, mentre non e ` emersa una relazione significativa tra la presenza di persone familiari e l’essere nella propria casa durante l’emergenza e i comportamenti di evacuazione. I risultati hanno inoltre rilevato associazioni significative tra la risposta emotiva del partecipante e il luogo: i partecipanti che si trovavano nella propria abitazione durante la situazione di pericolo hanno sperimentato piu` sintomi di panico, maggior disagio e piu` elevata percezione di pericolo nei diversi momenti dell’emergenza, rispetto a coloro che erano in luoghi pubblici. Infine, la presenza di persone familiari influenza i livelli di distress alla fine dell’emergenza. Si discutono alcune implicazioni di questi risultati per migliorare i progetti di prevenzione ed educazione sul comportamento umano in emergenza e migliorare la preparazione dei cittadini., The aim of this study is to explore the effect of some psychosocial factors on human behaviour during an emergency situation. In agreement with the observations of the theory of social attachment in disasters (Mawson 2005, 2007), people in danger experience feelings of attachment for familiar persons and places. These feelings have a reassuring effect, reducing or delaying the behaviour of evacuation. Participants were 173 survivors of several emergency situations: 42.4% were men and 57.6% were women with mean age 32.52 years (SD 13.68). Results evidenced a negative association between being with familiar people and delay in starting the evacuation, whereas the presence of familiar people or being at home during the danger situation were not significantly associated with evacuation. Findings also highlighted significant associations between participants’ emotional response and place: participants who were at home during the danger situation experienced more panic symptoms, distress, and perception of threat in the different moments of the evacuation in comparison with those who were in public buildings. Finally, it was concluded that the presence of familiar people had an influence on the level of distress during emergency situation. Here, we discuss some implications of these results for prevention and education programs on human behaviour during emergencies and for improving citizens’ preparedness.

What is the role of self-esteem in adolescents with idiopathic scoliosis under a conservative treatment?

  • D'Agata, Elisabetta
  • Pérez Testor, Carles
  • Negrini, S.
  • Rigo, M.
Self-esteem is defined as a “positive or negative orientation toward oneself” or “a feeling of self-appreciation” (Rosenberg, 1965). In AIS literature, there are contrasting results about the relation between Self-esteem and treatments (Masso et al., 2002; Zhang et al, 2011). Evaluating any correlations between Self-esteem with Health Related Quality of Life (HRQOL) and Body Satisfaction in adolescents with IS.

Un cop d’ull a Resource description & acces (RDA) i al seu futur

  • Estivill Rius, Assumpció
Es tracta d’una sessió introductòria que se centra en els aspectes més generals de la nova normativa: el marc conceptual en el qual es fonamenta la RDA (els models FRBR i FRAD), els objectius, l’organització de les normes, el nou vocabulari, la continuïtat amb les AACR2 i els punts de divergència, els beneficis que s’espera obtenir del nou codi, etc. El seu objectiu principal és fer una primera introducció de les regles per sensibilitzar els catalogadors dels canvis que tindran lloc a mig termini.
