Culture, sexuality and youth: experience of our young people in London

Se ha realizado un estudio etnográfico para saber cómo los jóvenes almerienses (con unas edades comprendidas entre 20-24 años) viven su sexualidad en Londres. Nos interesa específicamente obtener información sobre los choques culturales que han experimentado a nivel social y sexual debido a la convivencia con otros grupos culturales y con la población autóctona, también los cambios que se han producido en su identidad cultural tras su experiencia en Londres, y por último, cómo el contacto con otros grupos culturales ha influenciado en su relaciones afectivas, y en definitiva, en su sexualidad. Para esta finalidad, la investigación se ha desarrollado en dos etapas, la primera, tiene lugar en Almería y se seleccionan jóvenes que han estado trabajando o estudiando en Londres durante más de un año y que han regresado a España, la segunda y última fase, se desenvuelve en el propio contexto de la vida diaria de los jóvenes almerienses en Londres, exactamente en una residencia de estudiantes extranjeros y autóctonos. La recogida de información se ha llevado a cabo mediante entrevistas semiestructuradas, grupos de discusión y observación participante.An ethnographical research has been carried out in order to learn how youth from Almeria (aged from 20 to 24 years old) live their sexuality in London. We are specifically interested in getting information regarding cultural shocks that these youth have experienced in a social and sexual level due to the coexistence with people from different cultures including native population. We are also interested in discovering which changes, if any, have suffered their own cultural identity after the time passed in London. Lastly, we want to know if the contact with people from other cultures has any kind of influence over their affective and sexual relations. This research have been carried out in two stages. In the first of them, performed in Almeria, youth who have been working or studying in London for more of one year and who are back in Spain are recruited for study purposes. The second stage take place in the context of the normal day to day of these Spanish youth in London, specifically in a residence for native and foreigner students. The information was gathered trough semistructured interviews, discussion groups and intervening observation

Carbon materials as template for the preparation of mixed oxides with controlled morphology

Resumen del libro de actas del Congreso: 5th Czech-Italian-Spanish Conference on Molecular Sieves and Catalysis, celebrado en Segovia del 16 al 19 de junio de 2013Bulk mixed oxide catalysts are widely used for many applications, such as catalysts for selective oxidation processes, electrocatalysts for fuel cells, gas sensors, and solid oxide electrolysers for the production of hydrogen. VPO (vanadium and phosphorous oxides) are one of the bulk mixed oxide materials which are of interest nowadays since they are active catalysts for saturated hydrocarbon activation. With the conventional synthesis procedures for preparing bulk mixed oxides is really difficult to control the morphology and the porous structure of these materials. In practice, there are just a few works about the synthesis of mixed oxide materials with controlled morphology. The aim of this work was to describe new approaches for the preparation of VPO mixed oxides materials with spherical morphology. A carbon material was prepared using cellulose as starting material by hydrothermal treatment with phosphoric acid at 200ºC and carbonized at 500ºC. SEM analysis showed that carbon spheres with diameter up to 0.5 m were prepared by this procedure. These phosphorous containing carbon material was impregnated with the appropriate amount of vanadium oxide species in order to obtain a monolayer of VOx species on the surface of the carbon materials following a procedure described previously (1). By this manner, a carbon supported VOx material with spherical morphology was obtained (VPO/Csph). The calcination of this material was optimized in order to obtain VPO spheres with diameter up to 1-2 m and with BET area values close to 100 m2/g. Figure 1 shows a SEM image of this sample (VPOsph). The presence of vanadium pyrophosphate phase, which has been described as the active phase of this catalytic system, was identified by XRD and Raman spectroscopy. Thus, the chemical composition as well as the morphology and porous structure of these new spherical materials makes them quite promising as catalysts

An approach to the application of shift-and-add algorithms on engineering and industrial processes

Different kinds of algorithms can be chosen so as to compute elementary functions. Among all of them, it is worthwhile mentioning the shift-and-add algorithms due to the fact that they have been specifically designed to be very simple and to save computer resources. In fact, almost the only operations usually involved with these methods are additions and shifts, which can be easily and efficiently performed by a digital processor. Shift-and-add algorithms allow fairly good precision with low cost iterations. The most famous algorithm belonging to this type is CORDIC. CORDIC has the capability of approximating a wide variety of functions with only the help of a slight change in their iterations. In this paper, we will analyze the requirements of some engineering and industrial problems in terms of type of operands and functions to approximate. Then, we will propose the application of shift-and-add algorithms based on CORDIC to these problems. We will make a comparison between the different methods applied in terms of the precision of the results and the number of iterations required.This research was supported by the Conselleria de Educacion of the Valencia Region Government under grant number GV/2011/043

Cambio normativo y cambio en los sistemas de información y control: El caso del olivar

En este trabajo pretendemos analizar el impacto que los cambios en la normativa comunitaria reguladora de las producciones agropecuarias, en la actualidad enmarcada en la Política Agraria Común, han tenido sobre el sector olivarero (aceite de oliva y aceituna de mesa) en nuestro país y más concretamente en nuestra comunidad autónoma, debido al peso específico que este sector tiene en el conjunto de la economía andaluza, un 23% de la producción final agraria. Este trabajo se va a enmarcar dentro de Teoría Institucional debido a su capacidad para explicar los cambios en las instituciones y organizaciones en función de fenómenos sociopolíticos y económicos en términos de relaciones causa-efecto. Proponemos el estudio de caso como método de análisis lo que conllevará al uso de técnicas de obtención de evidencia tales como el análisis documental, entrevistas, cuestionarios, observación no participante, etc. El objetivo final de este proyecto de investigación es analizar desde un punto de vista multidisciplinar los cambios producidos en el sector del olivar desde nuestra incorporación plena a la Comunidad Económica Europea en 1986, examinando igualmente la posible influencia que tendrá en el sector los cambios normativos que se deriven como resultado de la denominada Agenda 2000. De esta forma, pretendemos abarcar con nuestro proyecto aspectos tales como la proliferación y mejora del cultivo, la configuración global del sector del olivar y las distintas tipologías de empresas que operan en él –estrategia, tamaño, estructura, situación económico-financiera, resultados, etc.-, llegando, por último, a analizar los efectos sobre sus sistemas de control (SC)

Interview guideline for functional behhavior analysis in transsexual persons

La transexualidad es un fenómeno emergente. Por ello hay pocos instrumentos de evaluación psicológica. El objetivo de este artículo es mostrar a la comunidad de profesionales de la psicología clínica y de la intervención social un instrumento que puede facilitar esta tarea. Se realiza una breve introducción al fenómeno de la transexualidad y la evaluación psicológica en este campo, que casi siempre se centra en el diagnóstico o en otras variables generalmente de personalidad (rasgos de personalidad, depresión, ansiedad,…). Posteriormente se abordan los principales problemas que encuentra una persona transexual durante su proceso. Estos problemas son fuente potencial o real de conflictos psicológicos. Más tarde se describe brevemente la evaluación conductual muy olvidada en esta área. Por último se propone un nuevo instrumento esta la evaluación. El principal resultado es la Guía de Entrevista para el Análisis Funcional de Secuencias Conductuales (AFUSCO). Se concluye con la necesidad de más evaluación conductual en este campoTransgenderism is an emergent phenomenon. Thus there are few psychological assessment instruments. The aim of this paper is to show to the community of practitioners of clinical psychology and social intervention a tool in order to facilitate this task. A brief introduction to the phenomenon of transsexualism and psychological evaluation in this field is made. This almost always focuses generally on the diagnosis or other personality variables (like personality traits, depression, anxiety...). Later, the main problems that may happen while the transsexual processing are addressed. These problems are a real or potential source of psychological conflicts. Then, the behavioral assessment which is largely forgotten in this area is briefly described. Finally it’s proposed a new tool. The main result is the Interview Guide for the Functional Analysis of behavioral sequences (IGFABS). It’s concluded with the need for more behavioral assessment in this fiel

Frequency and Associated Factors of Suicidal Ideation in Patients with Chronic Obstructive Pulmonary Disease

COPD; Depression; SuicideEPOC; Depresión; SuicidioMPOC; Depressió; SuïcidiWe aimed to examine the prevalence of suicidal ideation in patients with chronic obstructive pulmonary disease (COPD) and the association between demographic and clinical variables and the occurrence of suicidal thoughts. This was a cross-sectional study. Sociodemographic and clinical data were recorded, and questionnaires were used to assess depressive symptoms (Beck Depression Inventory), comorbidities (Charlson Index), cognitive performance (Mini Mental State Examination), and quality of life (EuroQoL-5 dimensions and CAT). Specific questions about suicide-related behavior were included. Multivariate logistic regression analysis identified the significant factors associated with previous suicidal ideation and suicide attempts. The analysis included 1190 subjects. The prevalence of suicidal ideation and suicide attempts were 12.1% and 2.5%, respectively. Severely depressed patients had the highest prevalence of suicide-related behavior. The adjusted logistic model identified factors significantly associated with suicidal ideation: sex (odds ratio (OR) for women vs. men = 2.722 (95% confidence interval (CI) = 1.771–4.183)), depression score (OR = 1.163 (95% IC = 1.127–1.200)), and Charlson Index (OR 1.228 (95% IC 1.082–1.394)). Suicidal ideation is common in COPD patients, especially in women. While addressing suicidal ideation and suicide prevention, clinicians should first consider the management of depressive symptomatology and the improvement of coping strategies.The DeprEPOC study was funded by an unrestricted grant from Grupo Ferrer (Barcelona, Spain)

Linear and circular UWB millimeter-wave and terahertz monostatic near-field synthetic aperture Iimaging

Millimeter-wave and terahertz frequencies offer unique characteristics to simultaneously obtain good spatial resolution and penetrability. In this paper, a robust near-field monostatic ocusing technique is presented and successfully applied for the internal imaging of different penetrable geometries. These geometries and environments are related to the growing need to furnish new vehicles with radar-sensing devices that can visualize their surroundings in a clear and robust way. Sub-millimeter-wave radar sensing offers enhanced capabilities in providing information with a high level of accuracy and quality, even under adverse weather conditions. The aim of this paper was to research the capability of this radar system for imaging purposes from an analytical and experimental point of view. Two sets of measurements, using reference targets, were performed in the W band at 100 GHz (75 to 110 GHz) and terahertz band at 300 GHz (220 to 330 GHz). The results show spatial resolutions of millimeters in both the range (longitudinal) and the cross-range (transversal) dimensions for the two different imaging geometries in terms of the location of the transmitter and receiver (frontal or lateral views). The imaging quality in terms of spatial accuracy and target material parameter was investigated and optimized.This research was funded by the Ministry of Education and Science, Spain (TEC2016-78028-C3-1-P and TEC2016-78028-C3-2-P) and by the European FEDER funds
