Social exclusion and economic growth at the European Union: can social marketing and behavioral economics help us to overcome the problem?
The problem of poverty and social exclusion is growing nowadays in the European Union context, according to Eurostat (2015 and 2016). And, in spite of the fact that Europe 2020 Strategy is apparently focused on that situation, the perspectives are not promising. What could be happening? In this paper we analyze this issue from a Macromarketing approach, including elements from Behavioral Economics (stigmatization process and stress coping theories, going further than the “homo economicus” traditional model) to reach a better understanding, and recommending a combined public-private response to overcome the problem, using the elements that Marketing provide us (such as Social Marketing, Macro-social Marketing, Corporate Social Marketing and also traditional Commercial Marketing techniques, under a “fortune at the bottom of the pyramid” approach). Doing so, we do not only want to eradicate this sort of curse, but also to boost economic growth in an effective inclusive manner.Universidad de Málaga.

Conductivity and entanglement entropy of high dimensional holographic superconductors
We investigate the dependence of the conductivity and the entanglement
entropy on the space-time dimensionality in two holographic
superconductors: one dual to a quantum critical point with spontaneous symmetry
breaking, and the other modeled by a charged scalar that condenses at a
sufficiently low temperature in the presence of a Maxwell field. In both cases
the gravity background is asymptotically Anti de Sitter (AdS). In the large
limit we obtain explicit analytical results for the conductivity at zero
temperature and the entanglement entropy by a expansion. We show that the
entanglement entropy is always smaller in the broken phase. As dimensionality
increases, the entanglement entropy decreases, the coherence peak in the
conductivity becomes narrower and the ratio between the energy gap and the
critical temperature decreases. These results suggest that the condensate
interactions become weaker in high spatial dimensions.Comment: 38 pages, 7 figure
Improving the detection of the transport mode in the MobilitApp Android application
Millorar els algorismes de detecciĂł del medi de transport dels ciutadans de l'Ă€rea Metropolitana de Barcelona.El objetivo ha sido el de mejorar la aplicaciĂłn MobilitApp ya existente, para ello se han añadido dos mĂłdulos. El primer mĂłdulo que se ha añadido ha sido un detector de accidentes. Debido a que en los anteriores trabajos se estaba tratando con el acelerĂłmetro, nos pareciĂł interesante intentar sacar más provecho al acelerĂłmetro e incluir la funcionalidad de poder detectar cuando el mĂłvil ha sufrido un impacto. Una vez el impacto ha sido detectado se envĂa un mensaje de emergencia. El segundo mĂłdulo consiste en un podĂłmetro, MobilitApp cuenta los pasos del usuario y se presenta junto a una aproximaciĂłn de la distancia recorrida y del nĂşmero de calorĂas quemadas. Como Ăşltimo paso, hemos realizado un análisis sobre las gráficas que se han obtenido de los usuarios tomadas del acelerĂłmetro sobre metro o tren, y hemos comprobado su parecido con una señal sinusoidal. Esta caracterĂstica ayudará en futuros trabajos para identificar mejor el tipo de sistema de transporte utilizado por el usuario. Además, serĂa de gran ayuda para ahorrar baterĂa ya que la señal GPS serĂa menos utilizada.This study aims to improve an existing application for citizen mobility analytics: MobilitApp.
Two modules were added to the app in order to develop the desired functionalities.
The first module has been added is an accident detector. Because of the previous work
involves dealing with the accelerometer, it seemed interesting to try to get more out of the
accelerometer and include the functionality to detect when the phone has suffered an
impact. Once the impact has been detected, an emergency message is sent.
The second module consists of a pedometer, MobilitApp counts the number of the user’s
steps and presents them with an approximation of the distance walked and the number of
calories burned.
As a last step, we have made an analysis of the graphs that have been obtained from the
user’s accelerometers travelling on train or subway, and we have checked their
resemblance to a sinusoidal signal. This feature will help in future works to better identify
the type of public transportation system being used by the user. Besides, it would help to
save battery since the GPS signal will be less used.L’objectiu ha estat el de millorar l’aplicació MobilitApp ja existent, per això s’han afegit
dos mòduls.
El primer mòdul que s’ha afegit ha estat un detector d’accidents. A causa que en els
anteriors treballs s’estava tractant amb l’acceleròmetre, ens va semblar interessant
intentar treure més profit a l’acceleròmetre e incloure la funcionalitat de poder detectar
quan el mòbil ha patit un impacte. Un cop l’impacte ha estat detectat s’envia un missatge
d’emergència.
El segon mòdul consisteix en un podòmetre, MobilitApp compte els passos de l’usuari i
se’ls presenta amb una aproximació de la distà ncia recorreguda y de les calories
cremades.
Com a últim pas, em fet un anà lisi sobre les grà fiques que s’han obtingut dels usuaris
preses de l’acceleròmetre sobre metro o tren, i hem comprovat la seva semblança amb
una senyal sinusoĂŻdal. Aquesta caracterĂstica ens ajudarĂ en treballs futurs per identificar
millor el tipus de sistema de transport utilitzat per l’usuari. A més, seria de gran ajuda per
estalviar bateria ja que el senyal GPS seria menys utilitzat
