Análisis económico de la vacunación oral frente a tuberculosis bovina
Trabajo Fin de Máster: Master en investigación Básica y Aplicada en Recursos Cinegéticos.El incremento en la incidencia de la tuberculosis bovina (TB) en algunos países
desarrollados se debe principalmente a la infección de reservorios silvestres, destacando la importancia del jabalí europeo (Sus scrofa) como principal reservorio en España. La vacunación oral empleando cebos constituye una prometedora alternativa para el control de la TB. Las acciones para el control de una enfermedad deben ser económicamente sostenibles. Por lo tanto, el análisis del coste-beneficio en las estrategias de vacunación pasa a ser imprescindible. Es por ello que este trabajo tiene como objetivo principal determinar los costes directos e indirectos asociados a la
vacunación oral empleada de forma experimental en jabalí en España. Este análisis económico permitirá definir los costes de la vacunación en relación al impacto económico que conlleva en ganadería el sacrificio obligatorio de los animales afectados con M. bovis.Peer Reviewe
A century of Carlos Nadal (1917-1998): appraisal of his artwork, collecting and art market value
Se cumplen cien años del nacimiento de Carlos Nadal Ferreres (París, 1917 –
Sitges, 1998), uno de los últimos fauves . Cultivó la pintura con un estilo propio, colorista
y vital heredero de la joie de vivre fauvista. Como artista exitoso, sus obras se exponen en galerías nacionales e internacionales y está presente en numerosas colecciones, en su mayoría particulares. Aunque Nadal no fue coleccionista, resulta interesante analizar las series tituladas “Colecciones” o “Interiores” donde reúne cuadros-homenaje de sus
principales referentes artísticos. Su presencia en el mercado primario y secundario es
valorada internacionalmente de forma constante. Con todo, sorprende descubrir la
inexistencia de estudios en castellano sobre Carlos Nadal, habiendo recurrido a fuentes
primarias e inéditas. Por ello, una buena forma de celebrar su destacada trayectoria es
acercándonos a esta sugerente figura.This year we will commemorate the 100th birth anniversary of Carlos Nadal
Ferreres (Paris, 1917 – Sitges, 1998), one of the last fauves . Nadal’s own painting style,
coloristic and lively, inherited of the fauvist ́s joie de vivre . As a successful artist, his
artworks will be displayed in national and international galleries and it is part of many
collections, most of them private. Although Nadal was not a collector, it is interesting to
analyse the series of “Collections” or “room interiors” where he presents homage-
paintings of his main art references. His presence on primary and secondary art markets
is internationally and constantly appreciated. However, it is surprising to discover the lack
of studies in Spanish about Carlos Nadal. I have studied principal sources and
unpublished documentation. Therefore, a good way to commemorate his distinguished
career is to elucidate this intriguing figure

New records of Orchids from Morocco
The exploration of the Rif Valley (Morocco) during 2010 revealed the
presence of some new taxa and records from Morocco. The new taxa are:
Orchis langei subsp. magrebensis and Ophrys neglecta var. riphaea. Ophrys
neglecta var. neglecta and Ophrys numida have been detected for the first time
in Morocco
Women’s disengagement from legal proceedings for intimate partner violence in southern Spain: Variables related to legal proceedings
This article studies the relationship between a set of variables related to the
legal process and women’s disengagement from legal proceedings against
their (ex)partners in Southern Spain. A total of 345 women answered a
questionnaire. Results evidenced that request for a protection order (PO),
granting such PO, imprisonment of the offender, and women’s perception of
who decided during the process were significantly related to disengagement
(medium effect size). In addition, a logistic regression model was developed
to predict disengagement with two variables: granting a PO and women’s
perception of who decided. Results are interpreted in terms of the necessity
that the judicial system gives support, protects, and provides women with
opportunities to participate in the recovery process.Junta de Andalucía 1071/0453Ministerio de Educación, Cultura y Deporte (España) FPU15/0037
Chemical abundances of stars with brown-dwarf companions
It is well-known that stars with giant planets are on average more metal-rich
than stars without giant planets, whereas stars with detected low-mass planets
do not need to be metal-rich. With the aim of studying the weak boundary that
separates giant planets and brown dwarfs (BDs) and their formation mechanism,
we analyze the spectra of a sample of stars with already confirmed BD
companions both by radial velocity and astrometry. We employ standard and
automatic tools to perform an EW-based analysis and to derive chemical
abundances from CORALIE spectra of stars with BD companions. We compare these
abundances with those of stars without detected planets and with low-mass and
giant-mass planets. We find that stars with BDs do not have metallicities and
chemical abundances similar to those of giant-planet hosts but they resemble
the composition of stars with low-mass planets. The distribution of mean
abundances of -elements and iron peak elements of stars with BDs
exhibit a peak at about solar abundance whereas for stars with low-mass and
high-mass planets the [X/H] and [X/H] peak abundances
remain at ~dex and ~dex, respectively. We display these
element abundances for stars with low-mass and high-mass planets, and BDs
versus the minimum mass, , of the most-massive substellar companion
in each system, and we find a maximum in -element as well as Fe-peak
abundances at jupiter masses. We discuss the
implication of these results in the context of the formation scenario of BDs in
comparison with that of giant planets.Comment: Accepted for publication in Astronomy & Astrophysic
