La visibilidad académica de la exclusión : descripción de un practicum desde la optatividad de Trabajo Social
[email protected] [email protected] trabajo que presentamos tiene por objeto dar a conocer la experiencia académica que permite la oportunidad de realizar los créditos prácticos, de las asignaturas Psicología Social de la Inadaptación e Intervención Psicosocial, (módulos que forman parte de las materias optativas del plan de estudios de Trabajo Social de la Universidad de Valencia y son impartidos por el profesor José R. Bueno Abad), a través de un Practicum en centros institucionales, en concreto en la entidad Cáritas Diocesana de Valencia, mediante la presencia de los alumnos de Trabajo Social en diversos programas dirigidos a personas sin hogar, enfermos mentales, personas afectadas por el VIH/ SIDA e inmigrantes. Al mismo tiempo pretendemos plantear una reflexión en torno al fenómeno de la exclusión: su conceptualización, tipologías, las políticas sociales que se están aplicando actualmente para propiciar un debate en torno a de qué manera inciden estas políticas sobre la intervención social en los colectivos en situación de exclusión.The present paper approaches the academicals experience that let to do the training credits of subjects such as Social Psychology of Maladjustment and Psychosocial Intervention. These subjects are optative in the studies planning of Social Work at University of València imparted by the professor José R. Bueno Abad. The aim is that the Social Work students do a practicum in institutional centres mainly in Cáritas Diocesana de Valencia. During this period student are involved in several programmes leading to homeless, mental ills, HIV-AIDS ills, and immigrants. Eventually, try to create a space of reflection about the exclusion problem: conceptions, typologies, present social policies in course to fight against it, and to urge a discussion about the incidence of Social policies in collectives of exclusion risk
Interest rate setting at the ECB: Individual preferences and collective decision making
We investigate whether the members of the Governing Council of the European Central Bank take into account the specific economic conditions of their states of origin, to set the interest rates for the euro area. Testing the national-based view against the Europeanist perspective is a challenging issue, because voting inside the Governing Council is secret, and the final outcome depends both on the individual preferences and the procedures followed by the Governing Council to arrive at a decision. Accordingly, we model interest rate setting as a two-stage process: first, each member of the Governing Council sets his/her preferred rate, and next the Governing Council meets and decides the actual figure. Our empirical analysis shows that domestic developments play a major role in determining the preferred interest rate of the each member; and that some members exert agenda setting power, that precludes some interest rate policies to be considered at the meeting
The therapeutic use of the dog in Spain: a review from a historical and cross-cultural perspective of a change in the human-dog relationship
En España, los estudios sobre los conocimientos tradicionales relacionados con la biodiversidad se han centrado en las plantas vasculares. Por este motivo, nuestra revisión se concentra en la identificación e inventario de recursos zooterapéuticos, en particular los que involucran al perro (Canis lupus familiaris Linnaeus, 1758) a lo largo del siglo XX hasta el presente. Se realizó una revisión sistemática cualitativa en los campos de etnomedicina, etnozoología y folklore. Se realizaron búsquedas automatizadas en las bases de datos y bibliotecas digitales más importantes. Todos los trabajos relacionados fueron examinados a fondo y se obtuvo información de 55 fuentes documentales. Hemos enumerado un total de 63 remedios para tratar y / o prevenir 49 enfermedades y afecciones humanas. En 20 de los informes documentados se utilizó el animal completo y se recomendó el uso de crías en 12 casos. La saliva fue el elemento de curación en 10 remedios, y las heces fueron la base terapéutica para nueve, mientras que la leche de perra fue para siete de ellos. Piel, piel y carne fueron los siguientes en importancia. Actualmente, los remedios curativos basados en el uso del perro no forman parte de la etnomedicina española y considerarlos así sería ahistórico. De hecho, la costumbre de permitir que un perro lama las heridas para ayudar en su curación y cicatrización ha sobrevivido en solo unos pocos grupos de personas. Sin embargo, podemos afirmar que el uso etnomédico del perro existe y se ha transferido a la "terapia asistida por animales".In Spain, studies about traditional knowledge related to biodiversity have focused on vascular plants. For this reason, our review concentrates on the identification and inventory of zootherapeutic resources, particularly those involving the dog (Canis lupus familiaris Linnaeus, 1758) throughout the twentieth century to the present. A qualitative systematic review in the fields of ethnomedicine, ethnozoology and folklore was made. Automated searches in the most important databases and digital libraries were performed. All related works were examined thoroughly and information was obtained from 55 documentary sources. We have listed a total of 63 remedies to treat and/or prevent 49 human illnesses and conditions. In 20 of the documented reports the whole animal was used and the use of pups was recommended in 12 cases. Saliva was the healing element in 10 remedies, and faeces were the therapeutic basis for nine, while bitch’s milk was for seven of them. Skin, fur and meat were next in significance. Currently, healing remedies based on the use of the dog are not part of Spanish ethnomedicine and considering them so would be ahistorical. Indeed, the custom of allowing a dog to lick one’s wounds to assist in their healing and cicatrisation has survived in only a few groups of people. However, we can state that the ethnomedical use of the dog exists and has been transferred to “animal-assisted therapy”.peerReviewe
Rock Andaluz: Nacimiento, evolución y caída
A finales de los 60 y llegada la década de los 70 los grupos españoles
miraban con entusiasmo lo que se hacía fuera de nuestras fronteras.
Eran grupos de rock progresivo que querían imitar a las grandes bandas
americanas e inglesas. A través de las bases militares americanas de
Morón de la Frontera en Sevilla y Rota en Cádiz entraran los testimonios
sonoros en formato de discos de vinilo que serán asimilados por esos
grupos de jóvenes ávidos de nuevos horizontes en todos los órdenes. Sin
embargo, la dictadura pondrá inconvenientes en el camino y creará
una censura a propósito para controlar los circuitos musicales.
Eran tiempos difíciles para desarrollar las libertades que deseaban los
jóvenes de entonces. Tiempos en los que te podían pedir la
documentación por el mero hecho de llevar pelo largo. Llevar melena y
ser varón en los 60 y 70 era problemático ciertamente. Te exponías a
insultos y desprecios allá donde entraras o por donde pasearas. Era
signo de malos hábitos y no buenas intenciones. Sin embargo, muchos
jóvenes se enfrentaron a todo eso y la música fue su inseparable
compañera de viaje.
El rock andaluz no nacerá de la noche a la mañana, tuvo su propia
evolución en el tiempo, pasando por unas etapas sociales complejas (el
tardofranquismo y la Transición). Va emergiendo a la vez que se va
suscitando en todo el país una serie de movimientos que se
entremezclaban entre lo social, lo cultural y lo político.
Antes de llamarse rock andaluz tiene varias denominaciones. Rock
fusión, rock con raíces, etc. esta catalogación quizás no fuera la más
acertada, ya que delimita el espectro musical a una región, una
comunidad, una zona concreta. El rock andaluz busca siempre su
propia identidad, sus músicos y compositores deciden apostar por
cantar en español y con acento andaluz. El flamenco, que antes era
sinónimo de antiguo, es asimilado por una nueva generación de
músicos que experimentan con él llevándoselo a su propio terreno. La
hibridación del flamenco es una constante.
Hoy sobrevive gracias al empeño de bandas como Medina Azahara y
su particular estilo propio identificativo, al nacimiento de nuevos grupos
que intentan crearse un camino dentro del estilo y a los distintos
homenajes al estilo que se llevan a cabo por parte de grupos afines que
interpretan versiones de los temas más emblemáticos.Universidad de Sevilla. Grado en Periodism
Ground-penetrating radar evaluation of the ancient Mycenaean monument Tholos Acharnon tomb
The assessment of cultural heritage requires high-resolution and non-destructive methodologies. Ground-penetrating radar is widely applied in the inspection of historical buildings. However, some structures with curved surfaces make the radar data acquisition process difficult and consequently the following data interpretation. This paper describes a case study concerning a circular and buried Greek monument. This monument is a magnificent tomb buried with irregular stones. However, its structure and the internal stones arrangement are unknown. Therefore, a radar survey was carried out to achieve two main objectives: (i) identification of hidden elements and arrangement of the stones and (ii) detection of specific zones where further restoration and maintenance should be recommended. The methodology for the radar data acquisition involves the use of a laser scan in order to define accurately each radar line, covering all the internal surface of the tomb. Radar data processing was developed by converting Cartesian coordinates into polar coordinates. This procedure allows defining better the internal anomalies, improving the radar data interpretation. The main results of the survey were three: (i) the presence of a hidden target buried in the corridor access to the tomb; (ii) the description of the internal structure of the walls of the tomb, defining the stones arrangement and the position and depth to the keystone; and (iii) the existence of delimited zones where the signal is highly attenuated, probably due to a high salt content.Peer ReviewedPostprint (author's final draft

shinyCurves, a shiny web application to analyse multisource qPCR amplification data: a COVID‑19 case study
[EN]Background Quantitative, reverse transcription PCR (qRT-PCR) is currently the gold-standard for SARS-CoV-2 detection and it is also used for detection of other virus. Manual data analysis of a small number of qRT-PCR plates per day is a relatively simple task, but automated, integrative strategies are needed if a laboratory is dealing with hundreds of plates per day, as is being the case in the COVID-19 pandemic. Results Here we present shinyCurves, an online shiny-based, free software to analyze qRT-PCR amplification data from multi-plate and multi-platform formats. Our shiny application does not require any programming experience and is able to call samples Positive, Negative or Undetermined for viral infection according to a number of user-defined settings, apart from providing a complete set of melting and amplification curve plots for the visual inspection of results. Conclusions shinyCurves is a flexible, integrative and user-friendly software that speeds-up the analysis of massive qRT-PCR data from different sources, with the possibility of automatically producing and evaluating melting and amplification curve plots.This project was supported by funding from the UPV/EHU (Accion Especial "Desarrollo e implementacion del test de diagnostico para COVID-19"). The funding body did not play any roles in the study design; nor in the data collection, analysis and interpretation, or in the writing of the paper
MHCP: Multimedia Hybrid Cloud Computing Protocol and Architecture for Mobile Devices
[EN] Multimedia cloud computing has appeared as a very attractive environment for the business world in terms of providing cost-effective services with a minimum of entry costs and infrastructure requirements. There are some architecture proposals in the related literature, but there is no multimedia cloud computing architecture with hybrid features specifically designed for mobile devices. In this article, we propose a new multimedia hybrid cloud computing architecture and protocol. It merges existing private and public clouds and combines IaaS, SaaS and SECaaS cloud computing models in order to find a common platform to deliver real time traffic from heterogeneous multimedia and social networks for mobile users. The developed protocol provides suitable levels of QoS, while providing a secure and trusted cloud environment.Jimenez, JM.; Díaz Santos, JR.; Lloret, J.; Romero Martínez, JO. (2019).

Energy Savings Consumption on Public Wireless Networks by SDN Management
[EN] In order to use the energy more efficiently, network algorithms and protocols must incorporate in their decision mechanisms some functions focused on saving energy. In this paper we have studied different features and parameters of wireless networks to establish their relationship with the power consumption. First, we have analyzed the variation of power consumption of access points (APs) in function of the antenna transmission power. Second, we have collected user information from real public wireless network to determine the real requirements of network resources in real time basis. Based on this information, a new extension for Openflow protocol over Software-Defined Networking (SDN) networks will be proposed to manage the wireless network, with the aim to keep the optimal network performance with minimal power consumption. This extension introduces new Openflow messages and a new function to be incorporated in SDN controllers and Openflow enabled devices. The proposal will be validated by appropriated simulations based on real scenarios: a shopping center and a municipal wireless network.This work has been supported by the Ministerio de Economía y Competitividad , through the Convocatoria 2014.

Complex signatures of selection for the melanogenic loci TYR, TYRP1 and DCT in humans
<p>Abstract</p> <p>Background</p> <p>The observed correlation between ultraviolet light incidence and skin color, together with the geographical apportionment of skin reflectance among human populations, suggests an adaptive value for the pigmentation of the human skin. We have used Affymetrix U133a v2.0 gene expression microarrays to investigate the expression profiles of a total of 9 melanocyte cell lines (5 from lightly pigmented donors and 4 from darkly pigmented donors) plus their respective unirradiated controls. In order to reveal signatures of selection in loci with a bearing on skin pigmentation in humans, we have resequenced between 4 to 5 kb of the proximal regulatory regions of three of the most differently expressed genes, in the expectation that variation at regulatory regions might account for intraespecific morphological diversity, as suggested elsewhere.</p> <p>Results</p> <p>Contrary to our expectations, expression profiles did not cluster the cells into unirradiated versus irradiated melanocytes, or into lightly pigmented versus darkly pigmented melanocytes. Instead, expression profiles correlated with the presence of Bovine Pituitary Extract (known to contain α-MSH) in the media. This allowed us to differentiate between melanocytes that are synthesizing melanin and those that are not. <it>TYR, TYRP1 </it>and <it>DCT </it>were among the five most differently expressed genes between these two groups. Population genetic analyses of sequence haplotypes of the proximal regulatory flanking-regions included Tajima's D, HEW and DHEW neutrality tests analysis. These were complemented with EHH tests (among others) in which the significance was obtained by a novel approach using extensive simulations under the coalescent model with recombination. We observe strong evidence for positive selection for <it>TYRP1 </it>alleles in Africans and for <it>DCT </it>and <it>TYRP1 </it>in Asians. However, the overall picture reflects a complex pattern of selection, which might include overdominance for <it>DCT </it>in Europeans.</p> <p>Conclusion</p> <p>Diversity patterns clearly evidence adaptive selection in pigmentation genes in Africans and Asians. In Europeans, the evidence is more complex, and both directional and balancing selection may be involved in light skin. As a result, different non-African populations may have acquired light skin by alternative ways, and so light skin, and perhaps dark skin too, may be the result of convergent evolution.</p
