The economic dis-information in Spain: case study of BFA-Bankia and its IPO.
The research this article is inscribe on comes from the belief that the current characteristics of the communications ecosystem generate the conditions for the occurrence of disinformation ploys due to informational insufficiency and partial information, abuse of fidelity to the source, the absence of interpretive and investigative journalism and the incomprehensibility of the information. The main objective is to determine the relationship between the journalistic handling of information as the creator of socialized realities and disinformation, from the semantic analysis and interpretation of content based of the digital editions of 3 Spanish printed media of daily rotation (El País, ABC and El Mundo), in retrospective to the listing in the stock market of BFA-Bankia (6th to 20th July, 2011) and prospectively on the interval after 10 consecutive days of losses (3rd to 17th May, 2012). The main results show endogenous journalistic dis-information or poor handling of the financial information made public through the analyzed media existed, due to the creation of positive expectations of the re-evaluation of the financial holding on the stock market. Meanwhile, the lack of investigative journalism, fidelity to official sources and the language used in financial reporting in the media outlets mentioned above, also contributed to the favorable scenario for dis-information

La crisis en Psicología Social : elementos para la discusión epistemológica del concepto de crisis
¿Existe una crisisen la Psicología Social actual? ¿Cuáles son sus principales factores? ¿Es una crisis epistemológica? Este artículo presenta un breve desarrollo de los principales argumentos que afirman o niegan la existencia de una situación crítica dentro del campo de la Psicología Social; también se incluyen algunas reflexiones ideológicas y epistemológicas acerca del problema. Los argumentos expuestos se vinculan principalmente a dos factores emergentes: la carencia de relevancia social en la investigación psicosocial y la polémica situación paradigmática. Ambos factores poseen un significado especial, en tanto que “nudos relacionales”, para la dinámica de la crisis, y ponen de relieve el momento transicional para la Psicología Social.Is there a,crisis in modern Social Psychology? Which are the main factors of it? Is it an epistemological breakdown? This article shows a brief development of the principal arguments -accepting or denying- the existente of a critical situation in the field of Social Psychology; it also includes some epistemological and ideological reflections about the problem. The exposed arguments are linked with two main emergent factors: the lack of social relevante in psychosocial research and the polemical paradigmatic situation. Both factors, with a special "relationship knot" significance to the crisis's dynamics, displaying a transitional moment for the Social Psychology, that is, from "modern" to "post-modern" sciences
Ejection of a Low Mass Star in a Young Stellar System in Taurus
We present the analysis of high angular resolution VLA radio observations,
made at eleven epochs over the last 20 years, of the multiple system T Tauri.
One of the sources (Sb) in the system has moved at moderate speed (5-10 km/s),
on an apparently elliptical orbit during the first 15 years of observations,
but after a close (< 2 AU) encounter with the source Sa, it appears to have
accelerated westward to about 20 km/s in the last few years. Such a dramatic
orbital change most probably indicates that Sb has just suffered an ejection -
which would be the first such event ever detected. Whether Sb will ultimately
stay on a highly elliptical bound orbit, or whether it will leave the system
altogether will be known with about five more years of observations.Comment: 4 pages, accepter in ApJ Letter

The scaling of the minimum sum of edge lengths in uniformly random trees
[Abstract] The minimum linear arrangement problem on a network consists of finding the minimum sum of edge lengths that can be achieved when the vertices are arranged linearly. Although there are algorithms to solve this problem on trees in polynomial time, they have remained theoretical and have not been implemented in practical contexts to our knowledge. Here we use one of those algorithms to investigate the growth of this sum as a function of the size of the tree in uniformly random trees. We show that this sum is bounded above by its value in a star tree. We also show that the mean edge length grows logarithmically in optimal linear arrangements, in stark contrast to the linear growth that is expected on optimal arrangements of star trees or on random linear arrangements.Ministerio de Economía, Industria y Competitividad; TIN2013-48031- C4-1-PXunta de Galicia; R2014/034Agència de Gestió d'Ajuts Universitaris i de Recerca; 2014SGR 890Ministerio de Economía, Industria y Competitividad; TIN2014-57226-PMinisterio de Economía, Industria y Competitividad; FFI2014-51978-C2-2-
Bounds of the sum of edge lengths in linear arrangements of trees
A fundamental problem in network science is the normalization of the
topological or physical distance between vertices, that requires understanding
the range of variation of the unnormalized distances. Here we investigate the
limits of the variation of the physical distance in linear arrangements of the
vertices of trees. In particular, we investigate various problems on the sum of
edge lengths in trees of a fixed size: the minimum and the maximum value of the
sum for specific trees, the minimum and the maximum in classes of trees (bistar
trees and caterpillar trees) and finally the minimum and the maximum for any
tree. We establish some foundations for research on optimality scores for
spatial networks in one dimension.Comment: Title changed at proof stag
Peasantry is neither created nor destroyed, it can only be transformed. Agrarian discourses in the Delta de l’Ebre and the Albufera de València
The following pages summarize the analysis of agrarian and environmental discourses and social representations in the Ebro Delta and the Albufera of Valencia. The first part of the article tries to synthesize in a theoretical way the evolution and perspectives of family agriculture. We intend to analyze the essential changes that have taken place in agriculture and have made it survive, despite the theoretical prognosis that announced the end of the familiar agriculture. The second part addresses the methodological question of our research. We have conducted 58 interviews and two discussion groups in which different social profiles have participated. The analysis of social discourses was complemented by the exploitation of data from agrarian censuses, as well as from databases related to the rice market. The conclusions summarize how the discourses of the peasantry point out the impossibility of shying away from the subalternity of agricultural activity that has been ostracized by economic development and bound to be polluting if it wants to be economically viable.En las páginas que siguen, se resume el análisis de los discursos agrarios y
medioambientales y las representaciones sociales en el Delta del Ebro y la Albufera de Valencia. La
primera parte del artículo trata de sintetizar de manera teórica la evolución y perspectivas de la
agricultura familiar. Pretendemos analizar los cambios esenciales acaecidos en la agricultura y que,
pese a todo pronóstico teórico, la han hecho sobrevivir. La segunda parte aborda la cuestión
metodológica de la investigación. Hemos realizado 58 entrevistas y dos grupos de discusión en los
que han participado perfiles sociales muy variados. El análisis de los discursos se complementó con la
explotación de datos del INE (censos agrarios y macromagnitudes agrarias), así como bases de datos
relacionadas con el mercado del arroz. Las conclusiones sintetizan cómo los discursos del
campesinado señalan la imposibilidad de rehuir la subalternidad de la actividad agrícola
que ha quedado condenada al ostracismo por el desarrollo económico y abocada a ser contaminante si quiere ser económicamente viabl
Irrigation distribution networks' vulnerability to climate change
Climate change will lead to changed demands on ex
isting irrigation systems. This paper presents a
methodology for investigating the performance of
irrigation networks under climate change, and
applies this to an irrigation network in Cordoba
, southern Spain. The methodology uses emission
scenarios (A2 and B2) developed by the Interg
overnmental Panel on Climate Change. A global
climate model (HadCM3) is used with downscali
ng to predict climate variables for 2050 and 2080
under the emission scenarios. Euro
pean agricultural policy scenario
s are used to predict future
cropping patterns. Irrigation water requirements are th
en estimated for various combinations of these
climate and cropping pattern scenarios, and the perfo
rmance of the irrigation network is evaluated in
terms of the equity and adequacy of pressure
at the outlets, using EPANET. The methodology was
applied to the Fuente Palmera irrigation district,
which supplies water on-demand for drip irrigation.
The results show that climate change would have
a major impact on network performance with the
existing cropping pattern, but that expected chang
es in cropping pattern would reduce this impact
