Flavor-dependent eigenvolume interactions in a hadron resonance gas
Eigenvolume effects in the hadron resonance gas (HRG) model are studied for
experimental hadronic yields in nucleus-nucleus collisions. If particle
eigenvolumes are different for different hadron species, the excluded volume
HRG (EV-HRG) improves fits to multiplicity data. In particular, using different
mass~-~volume relations for strange and non-strange hadrons we observe a
remarkable improvement in the quality of the fits. This effect appears to be
rather insensitive to other details in the schemes employed in the EV-HRG. We
show that the parameters found from fitting the data of the ALICE Collaboration
in central Pb+Pb collisions at the collision energy ~TeV entail the same improvement for all centralities at the same
collision energy, and for the RHIC and SPS data at lower collision energies.
Our findings are put in the context of recent fits of lattice QCD results.Comment: 4 figure
Operational approach to Bell inequalities: applications to qutrits
Bell inequalities can be studied both as constraints in the space of
probability distributions and as expectation values of multipartite operators.
The latter approach is particularly useful when considering outcomes as
eigenvalues of unitary operators. This brings the possibility of exploiting the
complex structure of the coefficients in the Bell operators. We investigate
this avenue of though in the known case of two outcomes, and find new Bell
inequalities for the cases of three outcomes and and parties. We
find their corresponding classical bounds and their maximum violation in the
case of qutrits. We further propose a novel way to generate Bell inequalities
based on a mapping from maximally entangled states to Bell operators and
produce examples for different outcomes and number of parties.Comment: 10 pages, no figures. A sign error in Eq.(10), appearing in the

Ésser al llindar. La performance drag king: un indret en pugna per establir nous i diferents ordres sociosexuals
El procĂ©s de recerca etnogrĂ fica entorn dels modes de producciĂł corporal i identitĂ ria en la performance drag king evidencia l’existència d’un sistema alternatiu de significats que pugnen per establir nous i diferents ordres. La performance drag king Ă©s un moviment que desterritorialitza ambdĂłs termes de la relaciĂł masculinitat/feminitat, extraient-los de les relacions que els dotaven d’intel·ligibilitat fins llavors, amb la intenciĂł de dinamitar-los a travĂ©s de l’experimentaciĂł i la construcciĂł d’una nova subjectivitat. La performance vehicula el conflicte amb l’ordre sociosexual hegemònic, en el sentit fenomenològic de l’experiència in-corporada, i manifesta l’estratègia de les agents en la impugnaciĂł simbòlica i material de l’ontologia de gènere. El present article pretĂ©n abordar els processos d’adaptaciĂł i adopciĂł de l’imaginari drag a la quotidianitat de la Lola, una de les persones informants d’una recerca mĂ©s extensa. Processos que esdevenen espais de continuĂŻtat, i no de ruptura. Una anĂ lisis etnogrĂ fica, emprant l’eina dels itineraris corporals que proposa l’antropòloga Mari Luz Esteban, que denota com l’experimentaciĂł amb el propi cos en la performance drag, interpel·la la coherència de l’enginyeria social de la “normalitat”. Apareixent, aixĂ, un reguitzell de violències a l’espai pĂşblic, davant l’ambivalència i la inintel·ligibilitat que ofereixen les agents qui performen.

Abstract
Ethnographic research on modes of corporal and identity construction in drag king performance demonstrates the existence of an alternative system of meanings struggling to establish new and different sociosexual orders. Drag king performance is a movement that blurs masculinities and femininities, removing them from the field that made them intelligible with the aim of demolishing them by constructing and experimenting with a new subjectivity. The performance conveys rejection of the hegemonic sociosexual order in the phenomenological sense of embodied experience, and shows the strategy of the actors in contesting the ontology of gender both symbolically and materially. This article offers an overview of the processes of adaptation and adoption of the drag imaginary into the everyday life of Lola, a key informant. These processes create spaces of continuity rather than rupture. The ethnographic analysis is based on the analytic notion of corporal Itinerary developed by the anthropologist Mari Luz Esteban, which shows how experimenting with one’s own body in drag performance questions the coherence of the social engineering of “normality”. This challenge makes visible forms of violence in public spaces that arise in response to the ambivalence and unintelligibility offered by the performers.

La InclusiĂł dels alumnes amb necessitats educatives especials. AccĂ©s al currĂculum ordinari a travĂ©s dels Plans Individualitzats. TraducciĂł i adaptaciĂł de l’SPOT (instrument per analitzar els PIs).
Curs 2013-2014Actualment, és cada vegada més present en la nostra societat la paraula
inclusió i més concretament en el nostre à mbit educatiu, el concepte
d’educació inclusiva. Aquest treball pretén presentar una eina adaptada i
traduĂŻda al catalĂ anomenada Student Program Observation Tools, la qual
serveix per fer un anà lisi d’una de les mesures d’atenció a la diversitat: els
Plans Individualitzats, per tal de millorar-ne el contingut i Ă©sser una ajuda
per a les escoles però també perquè els alumnes amb necessitats
educatives especials puguin tenir accĂ©s al currĂculum ordinari com la resta
dels seus companys de classe.Nowadays, the word inclusion is more and more taken into consideration in
our society. In the educational community, the concept of inclusive
education is becoming a fundamental issue. This project has the intension
to propose a tool named Student Program Observation Tools, adapted and
translated to the Catalan language, with the aim to analyze one of the ways
of attending children with special educational needs: the Individualized
Education Programs. This instrument has been adapted in order to offer a
tool for Catalan schools to analyze and improve these programs so pupils
with special educational needs may have access to the general curriculum,
just like all the other pupils
