Hong, Jihyung, Novick, Diego, Treuer, Tamas, Montgomery, William, Haynes, Virginia S., Wu, Shenghu, Haro Abad, Josep Maria

BACKGROUND: Cultural views of Attention-Deficit/Hyperactivity Disorder (ADHD), differing healthcare systems and funding mechanisms, and the availability of mental health services can greatly influence the perceptions, diagnosis, and treatment of ADHD. There is, however, lack of information about treatment practice and the treatment decision-making process for ADHD, particularly in non-Western countries. Our study compared characteristics of paediatric patients newly diagnosed with ADHD symptoms…

Avenoza, Gemma, Soriano, Lourdes

Els darrers cinquanta anys han vist l'ascensió i la consolidació de les noves tecnologies de la informació, que han dominat la quotidianitat, tant que a hores d'ara una de les diferències més notòries entre la població als països desenvolupats no se situa en l'àmbit d'alfabetitzats vs. àgrafs (ja que molts dels alfabetitzats són en realitat àgrafs) sinó en la distinció entre natius digitals i immigrants digitals (Prensky 2001). I aquesta distinció afecta tots els camps de la…

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Luque Brugué, Laura

This TFM explores the figure of the witch as a disempowered symbol presented in Anne Rice’s trilogy The Lives of the Mayfair Witches (The Witching Hour, 1990; Lasher, 1993; Taltos, 1994). The witch has recently increased her presence in current cultural manifestations: shows like American Horror Story (2011-) or Salem (2014-) popularized again the witch and made her a trend in today’s popular culture. Of course, her role in history and literature has been largely explored in academia.…, Aquest TFM explora la figura de la bruixa com un símbol desempoderat tal i com es presenta en la trilogia d'Anne Rice, Les Vides de les Bruixes Mayfair (L’Hora de les Bruixes, 1990; Lasher, 1993; Taltos, 1994). La bruixa ha augmentat recentment la seva presència en les manifestacions culturals actuals: sèries de televisió com American Horror Story (2011-) o Salem (2014-) han tornat a popularitzar la bruixa i l’han convertit en una tendència en la cultura popular d'avui. Per descomptat…, Este TFM explora la figura de la bruja como un símbolo desempoderado tal y como se presenta en la trilogía de Anne Rice Las Vidas de las Brujas de Mayfair, La Hora de las Brujas, 1990; Lasher, 1993; Taltos, 1994).

‘In the Republic of Hapinness’, o, La hipertròfia del jo : una paròdia del narcissisme en la societat tardo-capitalista, segons Martin Crimp

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Méndez Panadés, Albert

The play In the Republic of Happiness by Martin Crimp (2012) begins with the unwelcome arrival of Uncle Bob, in the middle of a family’s Christmas lunch. He is the bearer of a confusing message, on which the play subsequently revolves; this message parodies ferociously one of the most predominant discourses in current capitalistic ideology: narcissistic individualism. This dissertation intends to analyse the notion of parody in order to contextualize it within Crimp’s dramaturgical gesture.…, L’obra In the Republic of Happiness (2012) de Martin Crimp comença amb l’arribada inesperada de l’Uncle Bob enmig d’un àpat familiar nadalenc, portador d’un enrevessat missatge, a partir del qual l’obra gira i parodia feroçment un dels discursos predominants de la ideologia capitalista actual: l’individualisme narcisista. En aquest estudi es pretén analitzar la noció de paròdia a fi de contextualitzar-la amb el gest dramatúrgic crimpià, alhora que aquesta s’articula amb l’anàlisi del…, La obra In the Republic of Happiness (2012) de Martin Crimp empieza con la llegada inesperada de Uncle Bob en medio de una comida familiar en Navidad, como portador de un mensaje embrollado, a partir del cual la obra gira y parodia ferozmente uno de los discursos predominantes de la ideología capitalista actual: el individualismo narcisista. En este estudio se pretende analizar la noción de parodia a fin de contextualizarla en el gesto dramatúrgico crimpiano, a la vez que esta se articula con…

Guinau Sellés, Marta, Playà i Pous, Elisabet, Aulinas Juncà, Meritxell, Rosell, Laura (Rosell i Ortiz), Rivero Marginedas, Lluís

Work on transversal competences in university degrees is a teaching line entirely established since the implementation of the European Credit Transfer System (ECTS). Nevertheless, undergraduate students present shortcomings in the development of some of these competences, especially on collaborative work, time management, oral and writing expression, and on the use of information resources. This paper presents a virtual tool and associated guidelines to enhance the information management during…



The First Simultaneous X-Ray/Radio Detection of the First Be/BH System MWC 656

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Ribó Gomis, Marc, Munar Adrover, P., Paredes i Poy, Josep Maria, Marcote Martin, Benito, Iwasawa, Kazushi, Moldón Vara, Francisco Javier, Casares, J., Migliari, S., Paredes Fortuny, Xavier

MWC 656 is the first known Be/black hole (BH) binary system. Be/BH binaries are important in the context of binary system evolution and sources of detectable gravitational waves because they are possible precursors of coalescing neutron star/BH binaries. X-ray observations conducted in 2013 revealed that MWC 656 is a quiescent high-mass X-ray binary (HMXB), opening the possibility to explore X-ray/radio correlations and the accretion/ejection coupling down to low luminosities for BH HMXBs. Here…

'El yacimiento de Sela (Jordania) La expansión imperial neo-babilónica en el altiplano de Edom a mediados del I milenio a.C.[The Site of Sela (Jordan)]

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Da Riva, Rocío

The site of as-Sila has been identified with Edomite Sela, frequently mentioned in the Bible. The site was important in the Iron Age (as demonstrated by the presence of many structures and the Neo-Babylonian cuneiform rock-inscription of king Nabonidus, 556-539 BCE), and also during the Nabatean and Roman periods. The survey work at Sela has revealed a very large site with a considerable number of structures related to water, and architectonic structures of varying sizes: rock-cut houses,…

Violenza, famiglia e genere. Il romanzo di ambiente poliziesco di Melania Mazzucco

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Ardolino, Francesco

The novel 'Un giorno perfetto' (A Perfect Day, 2005), which was adapted for the cinema by Ferzan Özpetek in 2008, is Melania G. Mazzucco's only novel to date to foray into the terrain of crime fiction.The frenetic pacing, the penchant for the ordinary and quotidian, and the fetishizing of weapons all work to create expectations that the narrative does not manage to bring to fruition. From the opening prolepsis, the novel's events diminish in significance and make way for a…

Consideracions sobre la crítica literària catalana. Diàleg entre un crític estranger i el seu geni familiar

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Ardolino, Francesco

En sortir de la biblioteca, el crític estranger va anar a l'estany i hi va llançar còdols, per fer-los rebotar. No hi havia ningú amb qui parlar de dèus antics ni de noves divinitats i va recordar els sopars amb uns escriptors, els cafès amb una poeta i les argúcies d'algun acadèmic. Amb tot, no va mirar-se a l'aigua, sinó que va ordenar les seves obsessions com si fossin el producte d'una nova conversa. I potser ho són.



Few-particle systems: An analysis of some strongly correlated states

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Barberán Falcón, Núria, Taron i Roca, Josep

The analysis of the quantum Hall response of a small system of interacting ultracold bosonic atoms through the variation of its Hall resistivity against the applied gauge magnetic field provides a powerful method to unmask its strongly correlated states in a quite exhaustive way. Within a fixed range of vaues of the magnetic field in the lowest Landau-level regime, where the resistivity displays two succesive plateaux, we identify the implied states as the Pfaffian and the state with filling…

Zurita, Adrián, Duran, Anna, Ribó i Trujillo, Josep M., El Hachemi, Zoubir, Crusats i Aliguer, Joaquim

The relationship between the acid-base chemistry and the supramolecular behavior of 5-(4-aminophenyl)-10,15,20-tris(4-sulfonatophenyl)porphyrin in acidic water is reported. A new species exhibiting a prominently red-shifted Q-absorption band at 742 nm is described which is in accordance with a hyperporphyrin-type spectrum of a J-aggregate in water. UV-vis spectroscopy and peak force microscopy reveal that depending on the pH value of the medium the porphyrin self-assembles into two structurally…



Movilidad residencial en edades avanzadas en España: una perspectiva metropolitana

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Pujadas, Isabel, 1949-, Bayona, Jordi, Rubiales Pérez, Miguel

En las áreas metropolitanas de Barcelona y Madrid, las dos mayores regiones metropolitanas de España, las migraciones internas de carácter residencial protagonizadas por mayores de 80 años doblan sus intensidades en apenas dos décadas. Este crecimiento se produce de forma similar en el conjunto de España, y se relaciona con la pérdida de independencia domiciliar producto de la edad. Desde un punto de vista territorial, estas migraciones se caracterizan por una sobrerepresentación de las salidas…

Causas de las desigualdades territoriales de la fecundidad: un estudio a escala metropolitana en el área barcelonesa

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Bayona, Jordi, Rubiales Pérez, Miguel, Gil Alonso, Fernando, Pujadas, Isabel, 1949-

Los comportamientos demográficos están experimentando una creciente segmentación en el interior de las regiones metropolitanas. Por ejemplo, los municipios de la Región Metropolitana de Barcelona (RMB) presentan diferentes intensidades de fecundidad, valores que incluso difieren en mayor grado que entre las provincias españolas. La principal hipótesis de este trabajo es que dichas diferencias se sustentan en la migración interna de parejas jóvenes ligadas al ciclo de vida, aunque la presencia…

Huertas García, Rubén, Gázquez Abad, Juan Carlos, Martínez López, Francisco J., 1975-, Esteban Millat, Irene

Identifying relevant attributes or variables is the first objective of conjoint analysis in market research. As a result of technological development, today it is common for researchers to use sequential experimental methods for adjusting design factors in successive phases. In particular, in the field of consumer behaviour these models are used predominantly for assessing subjective perceptions relating to the attributes of different products with high sensorial components (e.g. food, drinks…

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Samarra, F. I. P., Vighi, Morgana, Aguilar, Àlex, Víkingsson, G. A.

Among-individual variation in dietary preferences can impact community dynamics and be a driving force for evolutionary divergence, although it can be difficult to assess in free-ranging marine mammal populations. In this study, we investigate the existence of variation in isotopic niche within a population of putative herring-specialist killer whales. Isotopic ratios of carbon and nitrogen were measured in 67 skin biopsy samples from 56 individual killer whales, sampled in herring…

Tracking positive and negative effects of inequality on long-run growth [WP]

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Castells-Quintana, David, Royuela Mora, Vicente

Despite extensive research, there is still controversy on the effects of income inequality on economic growth. The literature proposes several transmission channels through which these effects may take place, and even the existence of two different forms of inequality. However, empirical studies have generally not distinguished between these channels, nor have their analyses included a consideration of the two forms of inequality and their separate effects on growth. In this paper we review the…

Diversity of introduced terrestrial flatworms in the Iberian Peninsula. A cautionary tale

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Alvarez-Presas, Marta, Mateos Frías, Eduardo, Tudò, Angels, Jones, Hugh, Riutort, Marta

Many tropical terrestrial planarians (Platyhelminthes, Geoplanidae) have been introduced around the globe. One of these species is known to cause significant decline in earthworm populations, resulting in a reduction of ecological functions that earthworms provide. Flatworms, additionally, are a potential risk to other species that have the same dietary needs. Hence, the planarian invasion might cause significant economic losses in agriculture and damage to the ecosystem. In the Iberian…

Causes and consequences of individual variability and specialization in foraging and migration strategies of seabirds

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Phillips, Richard, A, Lewis, Sue, González-Solís, Jacob, Daunt, Francis

Technological advances in recent years have seen an explosion of tracking and stable isotope studies of seabirds, often involving repeated measures from the same individuals. This wealth of new information has allowed the examination of the extensive variation among and within individuals in foraging and migration strategies (movements, habitat use, feeding behaviour, trophic status, etc.) in unprecedented detail. Variation is underpinned by key life-history or state variables such as sex, age…



Teorías de la referencia, 'filosofía experimental' y calibración de intuiciones

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Pérez Otero, Manuel, 1964-

E. Machery y algunos colaboradores suyos han utilizado datos sobre encuestas para criticar el anti-descriptivismo sobre los nombres propios de Kripke. Presento aquí diversos inconvenientes de esas encuestas. Algunas de mis objeciones conciernen a su ambigüedad. En particular, las respuestas que según Machery et al. revelan intuiciones descriptivistas pueden interpretarse como respuestas anti-descriptivistas, por razones que por lo que yo sé nadie ha destacado hasta ahora. Además, los casos…

Guillamat Bassedas, Pau, Ignés i Mullol, Jordi, Sagués i Mestre, Francesc

Active matter embraces systems that self-organize at different length and time scales, often exhibiting turbulent flows. Here, we use a quasi-two-dimensional nematically ordered layer of a protein-based active gel to experimentally demonstrate that the geometry of active flows, which we have characterized by means of the statistical distribution of eddy sizes, can be reversibly modified. To this purpose, the active material is prepared in contact with a thermotropic liquid crystal, whose…

En el presente trabajo estudiamos la creencia en la existencia de tempestarii o inmissores tempestatum en la Hispania tardoantigua. A pesar de la escasez de fuentes para dicho tema, éstas nos permiten aseverar que en la península Ibérica la gente reconocía como reales los individuos capaces de provocar tormentas con su sola voluntad. Estas fuentes corresponden a dos leyes de Chindasvinto, que manifiestan la preocupación de las autoridades por los «hacedores de tormentas» que arruinaban las…



Business taxes and the electoral cycle

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Foremny, Dirk, Riedel, Nadine

The purpose of this paper is to assess whether the timing of elections affects tax policy choices. To do so, we exploit information on the German local business tax which is set autonomously by German municipalities. As the dates for local council elections vary across German states, the data allows us to disentangle effects related to the timing of elections from common trends. The findings support the notion of a political cycle in tax setting as the growth in local business tax rates is…

Castells, Antoni (Castells Oliveres)

Després de la Segona Guerra Mundial, la figura de Keynes i el keynesianisme van quedar irremeiablement units a la idea de la utilització del pressupost per a la regulació de la demanda i del cicle econòmic.1 Poc importa que això es correspongués de manera massa estricta amb la realitat. De fet, ni aquest era el punt més important del pensament de Keynes, ni la materialització concreta que va acabar adquirint la política fiscal durant els anys d'hegemonia del pensament keynesià (la coneguda…

Raster, Peter, Späth, Andreas, Bultakova, Svetlana, Gorostiza Langa, Pablo Ignacio, König, Burkhard, Bregestovski, Piotr

We have prepared a series of new and some literature-reported GABA-amides and determined their effect on the activation of GABA A -receptors expressed in CHO cells. Special attention was paid to the purification of the target compounds to remove even traces of GABA contaminations, which may arise from deprotection steps in the synthesis. GABA-amides were previously reported to be partial, full or superagonists. In our hands these compounds were not able to activate GABA A -receptor channels in…

Activated BRAF mutations affecting the mitogen-activated protein kinases (MAPK) pathway are present in 50% of metastatic melanomas. Targeted therapies have been developed to block such mutations (1, 2). There is a risk of other components of the MAPK signalling pathway, such as MEK, being reactivated after the use of BRAF inhibitors (3-5). Given the evidence of drug resistance and side-effects of BRAF inhibitors, combined treatments with BRAF and MEK inhibitors are being tested in clinical…

<p> We attempted the calculation of an accurate equilibrium constant for the dimerization process of enantiomerically pure Zn-1 using UV-vis dilution experiments. At millimolar concentration Zn-1 is involved in a chemical exchange process between its monomeric and dimeric state that is slow on the 1H NMR timescale. We performed variable-temperature 1H NMR experiments in CDCl3 solution to determine the dimerization constant value at different temperatures and performed a van&rsquo;t…

Descriptor Analysis in Methanol Conversion on Doped CeO2(111): Guidelines for Selectivity Tuning

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Capdevila-Cortada, Marçal, López, Núria

<p> Descriptors are crucial to systematize and optimize activity, selectivity, and stability of catalysts. Adsorption energies have usually been taken as the main representative parameter that can summarize reaction energies and activation barriers for simple reactions on relatively simple reaction sites. However, more chemically sound terms, which can be directly mapped to experiments, would be more desirable. Besides, larger molecules with more than one potentially active position and…



Multigrid-Based Methodology for Implicit Solvation Models in Periodic DFT

Repositorio: Recercat: Dipósit de la Recerca de Catalunya
Garcia-Ratés, Miquel, López, Núria

<p> Continuum solvation models have become a widespread approach for the study of environmental effects in Density Functional Theory (DFT) methods. Adding solvation contributions mainly relies on the solution of the Generalized Poisson Equation (GPE) governing the behavior of the electrostatic potential of a system. Although multigrid methods are especially appropriate for the solution of partial differential equations, up to now, their use is not much extended in DFT-based codes…



Enantioselective Vinylogous Organocascade Reactions

Hepburn, Hamish B., Dell’Amico, Luca, Melchiorre, Paolo

<p> Abstract</p> <p> Cascade reactions are powerful tools for rapidly assembling complex molecular architectures from readily available starting materials in a single synthetic operation. Their marriage with asymmetric organocatalysis has led to the development of novel techniques, which are now recognized as reliable strategies for the one-pot enantioselective synthesis of stereochemically dense molecules. In recent years, even more complex synthetic challenges have been…



Light-triggered Enantioselective Organocatalytic Mannich-type Reaction

Hepburn, Hamish B., Magagnano, Giandomenico, Melchiorre, Paolo

<div> <p> Abstract</p> <p> Disclosed herein is a photochemical organocatalytic strategy for the direct enantioselective Mannich-type reaction of 2-alkyl-benzophenones and cyclic imines. The chemistry exploits the light-triggered enolization of 2-alkyl-benzophenones to generate transient hydroxy-<em>o</em>-quinodinomethanes. These fleeting intermediates can be stereoselectively intercepted by imines upon activation with a chiral organic catalyst,…

Roso, Sergio, Güel, Frank, Martínez-Alanis, Pauylina R., Urakawa, Atsushi, Llobet, Eduard

<p> ZnO nanowires (NWs) oriented in three different directions were synthesized via the vapour-liquid-solid technique over c-, r- and a-plane sapphire substrates. Gas sensing properties of these samples against reducing and oxidizing gases were examined. ZnO NWs grown on the c-plane substrate showed the highest response to oxidizing gases (NO<sub>2</sub>), while those grown on the a-plane substrate were more responsive to reducing one (ethanol). According to the insights…

<p> A molecular water oxidation catalyst based on the copper complex of general formula [(Lpy)CuII]2-, 22-, (Lpy is 4-pyrenyl-1,2-phenylenebis(oxamidate) ligand) has been rationally designed and prepared to support a more extended &pi;-conjugation through its structure in contrast with its homologue, the [(L)CuII]2- water oxi-dation catalyst, 12- (L is o-phenylenebis(oxamidate)). The catalytic performance of both catalysts has been comparatively studied in homogeneous phase and in…



Magnetically-actuated mesoporous nanowires for enhanced heterogeneous catalysis

Serra, Albert, Grau, Sergi, Gimbert-Suriñach, Carolina, Sort, Jordi, Nogues, Josep, Valles, Elisa

<p> We study the optimization of the catalytic properties of entirely magnetic Co&ndash;Pt compact and mesoporous nanowires of different diameters (25&ndash;200&nbsp;nm) by using magnetic actuation. The nanowires are a single-entity, robust, magnetic-catalyst with a huge catalytically-active surface area. We show that apart from conventional parameters, like the size and morphology of the nanowires, other factors can be optimized to enhance their catalytic activity. In…
