Los incumplimientos del Derecho de la Unión Europea y su repercusión sobre las comunidades autónomas: Los asuntos Magefesa y vacaciones fiscales vascas
La finalidad del Real Decreto 515/2013 era establecer un mecanismo de repercusión
de la totalidad de las responsabilidades derivadas de las infracciones del Derecho de la UE a
las CCAA cuya conducta habÃa originado el incumplimiento. No obstante, los Estados tienen
unos deberes previos de prevención de las violaciones del Derecho de la UE de tal forma que, si no
cumplen con ellos, deberÃan asumir una parte de las sanciones impuestas por el TJUE. Los asuntos
Magefesa y Vacaciones fiscales vascas constituyen los primeros casos en los que se ha repercutido
dichas responsabilidades a pesar de que el propio Estado no habÃa cumplido sus deberes previos de prevenciónThe aim of 515/2013 Regulation was to create a mechanism to fully pass on the liability
of the infringements of European Union law to the territorial entity whose non compliance had
caused it. Nontheless, it is a States previous duty to establish the necessary mechanism to prevent
the European Union law infringements of its territorial entities. Consequently, the absence
of this prevention mechanisms would entail the States liability for part of the European Union
Court of justice imposed sanctions on the territorial entities due to their infringments. The fi rst
cases in which the whole liability had been passed on to the according territorial entity, although
the State have not complied with its duty to create prevention mechanisms, were Magefesa and Vacaciones fiscales vasca
Cures infermeres a una persona laringuectomitzada
Treballs Finals de Grau de l'Escola Universitaria d'Infermeria, Universitat de Barcelona, Curs: 2014-2015, Tutor: MarÃa Teresa Luis RodrigoAquest procés de cures analitza el cas del Josep, un personatge fictici en la
història de vida del qual he intentat fer un recull de les principals caracterÃstiques
de tots aquells malalts que vaig conèixer i dels que vaig tenir cura durant les
meves practiques al servei d’otorinolaringologia.
En Josep és un home de 64 anys diagnosticat de cà ncer de laringe i a qui es
practica una laringuectomia total, extirpant-li tota la laringe. Conseqüentment
perd la capacitat de fonació.
Aquesta situació de pèrdua d'una part corporal (la laringe) i de la funció que
exercia (la parla), a la que s’uneix la percepció de pèrdua definitiva del seu estil
de vida, dona lloc a l’aparició d’un procés de dol que es manifestat per la persona
amb trastorns de la son i manifestacions verbals d’ansietat.
L’objectiu de les cures infermeres (i consegüentment del procés de cures) és
ajudar al Josep a assolir una resposta adaptada davant d’aquests canvis, per a
que pugui arribar a l’acceptació i maneig adequat del seu nou estat de salut
Las desigualdades de género en las ONG de desarrollo: discursos prácticas y procesos de cambio
Las ONG, como cualquier otro tipo de organizaciones sociales, reflejan las desigualdades de género en su estructura y funcionamiento interno. Este artÃculo va dirigido a analizar dichas desigualdades en las ONG de desarrollo, a través del estudio de las prácticas, dinámicas y discursos que se producen en el interior de las mismas. En este artÃculo se va a hacer especial hincapié en uno de los efectos de la desigualdad, la (in)visibilidad de las mujeres en este tipo de entidades, considerando las dos dimensiones de este fenómeno. Por un lado, se profundizará en la invisibilidad de las cuestiones de género, derivada de la desigualdad existente dentro de este tipo de organizaciones.Y, por otro, se estudiará la excesiva visibilidad de aquello que se sale de la norma, a partir de los procesos de cambio en los roles de género que se están produciendo en algunas ONGD
Reducing the fine-tuning of gauge-mediated SUSY breaking
Despite their appealing features, models with gauge-mediated supersymmetry
breaking (GMSB) typically present a high degree of fine-tuning, due to the
initial absence of the top trilinear scalar couplings, . In this paper,
we carefully evaluate such a tuning, showing that is worse than per mil in the
minimal model. Then, we examine some existing proposals to generate
term in this context. We find that, although the stops can be made lighter,
usually the tuning does not improve (it may be even worse), with some
exceptions, which involve the generation of at one loop or tree level. We
examine both possibilities and propose a conceptually simplified version of the
latter; which is arguably the optimum GMSB setup (with minimal matter content),
concerning the fine-tuning issue. The resulting fine-tuning is better than one
per mil, still severe but similar to other minimal supersymmetric standard
model constructions. We also explore the so-called "little
problem", i.e. the fact that a large -term is normally accompanied by a
similar or larger sfermion mass, which typically implies an increase in the
fine-tuning. Finally, we find the version of GMSB for which this ratio is
optimized, which, nevertheless, does not minimize the fine-tuning.Comment: 16 pages, 11 figures, 1 appendix. Discussion extended, matches EPJC

Entre la tradición y la modernidad : las parejas españolas de doble ingreso
La participación social de las mujeres, sobre todo su incorporación al mercado de trabajo, es uno de los cambios sociales más significativos de las últimas décadas. Sin embargo, a pesar de la vinculación que existe entre la situación de las mujeres dentro y fuera de la familia, apenas hay investigaciones que nos permitan conocer si han variado y cómo lo han hecho las relaciones de género en el ámbito privado. Este artÃculo se centra en entender cómo se construyen las parejas modernas y con qué obstáculos se encuentran a la hora de poner en práctica formas de relación igualitarias.The participation of women in social life, in particular their incorporation into the labour market, has been one of the more significant changes in the last decades. Although there is a link between the situation of women inside and outside the family, not enough research has been done to allow us to know if these changes in the public sphere are transferred to the private one. This paper tries to discover how modern couples build up their relationships and which are the obstacles to establish egalitarian couples
The Contagion Effects of Repeated Activation in Social Networks
Demonstrations, protests, riots, and shifts in public opinion respond to the
coordinating potential of communication networks. Digital technologies have
turned interpersonal networks into massive, pervasive structures that
constantly pulsate with information. Here, we propose a model that aims to
analyze the contagion dynamics that emerge in networks when repeated activation
is allowed, that is, when actors can engage recurrently in a collective effort.
We analyze how the structure of communication networks impacts on the ability
to coordinate actors, and we identify the conditions under which large-scale
coordination is more likely to emerge.Comment: Submitted for publicatio
What is a Natural SUSY scenario?
The idea of "Natural SUSY", understood as a supersymmetric scenario where the
fine-tuning is as mild as possible, is a reasonable guide to explore
supersymmetric phenomenology. In this paper, we re-examine this issue in the
context of the MSSM including several improvements, such as the mixing of the
fine-tuning conditions for different soft terms and the presence of potential
extra fine-tunings that must be combined with the electroweak one. We give
tables and plots that allow to easily evaluate the fine-tuning and the
corresponding naturalness bounds for any theoretical model defined at any
high-energy (HE) scale. Then, we analyze in detail the complete fine-tuning
bounds for the unconstrained MSSM, defined at any HE scale. We show that
Natural SUSY does not demand light stops. Actually, an average stop mass below
800 GeV is disfavored, though one of the stops might be very light. Regarding
phenomenology, the most stringent upper bound from naturalness is the one on
the gluino mass, which typically sets the present level of fine-tuning at
. However, this result presents a strong dependence on the HE
scale. E.g. if the latter is GeV the level of fine-tuning is four
times less severe. Finally, the most robust result of Natural SUSY is by far
that Higgsinos should be rather light, certainly below 700 GeV for a
fine-tuning of or milder. Incidentally, this upper bound is not
far from TeV, which is the value required if dark matter is made of
Higgsinos.Comment: 41 pages, 8 figures, 9 tables. References added, matches JHEP

Two-photon transitions driven by a combination of diode and femtosecond lasers
We report on the combined action of a cw diode laser and a train of
ultrashort pulses when each of them drives one step of the 5S-5P-5D two-photon
transition in rubidium vapor. The fluorescence from the 6P_{3/2} state is
detected for a fixed repetition rate of the femtosecond laser while the
cw-laser frequency is scanned over the rubidium D_{2} lines. This scheme allows
for a velocity selective spectroscopy in a large spectral range including the
5D_{3/2} and 5D_{5/2} states. The results are well described in a simplified
frequency domain picture, considering the interaction of each velocity group
with the cw laser and a single mode of the frequency comb.Comment: 4 pages, 4 figure
