Mayores, participación y servicios sociales : los órganos participativos para personas mayores en los servicios sociales de la provincia de Sevilla

Programa de Doctorado en Liberalismo y Democracia en el Mundo ContemporáneoLa tesis se centra, fundamentalmente, en las relaciones que los gobiernos mantienen con la ciudadanía en el ámbito local, en concreto con el colectivo de personas mayores en el contexto de los servicios sociales de carácter comunitario, con el fin de facilitar su participación en la toma de decisiones en todas aquellas políticas públicas que les afectan. Subyace la idea de un gobierno de tipo relacional que pueda posibilitar cohesión social, construcción de comunidad y una sociedad más democrática, todo ello unido a la idea de empoderamiento de la sociedad civil. La investigación identifica, describe y analiza los órganos de participación que las administraciones públicas de la provincia de Sevilla han constituido para hacer posible la participación del colectivo de personas mayores en el análisis, diseño, ejecución, evaluación y la toma de decisiones en aquellas políticas públicas locales que les afectan de manera directa, y que grado de eficacia y eficiencia tienen. Estos órganos participativos de mayores están integrados en el Sistema Público de Servicios Sociales y más concretamente en el ámbito comunitario, en los cuáles se producen el intercambio y la colaboración entre diferentes actores como son los políticos, los profesionales y las personas mayores que se hace necesario clarificar. Además se aportan elementos para descubrir cuáles son las ventajas y dificultades que se dan para hacer efectiva la participación del colectivo de personas mayores en la toma de decisiones públicas.Universidad Pablo de Olavide.

A survey of the genera Sarcodictyon Forbes, 1847, and rolandia Lacaze-Duthiers, 1900, (anthozoa: octocorallia) in the North-eastern Atlantic and the Mediterranean

Sarcodictyon catenatum Forbes, 1847, is a common species in the Atlantic and the Mediterranean. However, often it has been mistaken for Rolandia coralloides Lacaze-Duthiers, 1900. On the basis of British and Mediterranean material we studied the main characters for distinguishing S. catenatum. We consider Rolandia coralloides Lacaze-Duthiers, 1900, to be a valid species and we assign to it all the material named Rolandia rosea by S. Weinberg (1978). Furthermore, a histological study confirmed that R. coralloides typically forms groups of polyps embedded in a common coenenchyme. Therefore, the possibility of transferring R. coralloides from Stolonifera to Alcyonacea is discussed. Evagorgia rosea Philippi, 1842, is here considered to be a nomen dubium

Aplicaciones de blockchain en IoT y computación en la niebla

Desde su concepción en el 2008, la tecnología blockchain ha causado un gran interés en los últimos años. La aplicación inicial fue en el ámbito de las criptomonedas, dando soporte a Bitcoin. Este hecho ya de por sí supuso una revolución en el ámbito de la economía, pues la tecnología hacía posible prescindir de intermediarios (es decir, bancos y entidades financieras) en las transacciones económicas, ahorrando costes y evitando un control centralizado de la información registrada en la blockchain. Más adelante, la tecnología ha evolucionadopara incluir sobre ella la posibilidad de registrar lógica de negocio (es decir, código informático) en la propia blockchain a través de los contratos inteligentes. Esto, junto con el desarrollo de plataformas que permiten implementar blockchains con acceso controlado, ha abierto la puerta a un sinfín de aplicaciones más allá de las criptomonedas. Por otro lado, el concepto de internet de las cosas (IoT, en inglés), donde objetos cotidianos se conectan a internet, generando cantidades ingentes de datos que procesar (usualmente en lo que se conoce como computación en la niebla), es un campo de investigación e innovación que también ha generado gran interés de la industria y la academia en los últimos años. Las tecnologías IoT suponen un complemento perfecto para dotar de conexión con el mundo real a la información almacenada en la blockchain. En este trabajo realizaremos una breve introducción a blockchain y al internet de las cosas y revisaremos algunas aplicaciones que combinan ambas temáticas. Finalizaremos con una pequeña introducción a la línea de investigación sobre blockchain en entornos IoT que llevamos a cabo en el Instituto de Investigación en Informática de Albacete (I3A) de la Universidad de Castilla-La Mancha

Microstructural, spectroscopic, and antibacterial properties of silver-based hybrid nanostructures biosynthesized using extracts of coriander leaves and seeds

Coriander leaves and seeds have been highly appreciated since ancient times, not only due to their pleasant flavors but also due to their inhibitory activity on food degradation and their beneficial properties for health, both ascribed to their strong antioxidant activity. Recently, it has been shown that coriander leaf extracts can mediate the synthesis of metallic nanoparticles through oxidation/reduction reactions. In the present study, extracts of coriander leaves and seeds have been used as reaction media for the wet chemical synthesis of ultrafine silver nanoparticles and nanoparticle clusters, with urchin- and tree-like shapes, coated by biomolecules (mainly, proteins and polyphenols). In this greener route of nanostructure preparation, the active biocompounds of coriander simultaneously play the roles of reducing and stabilizing agents. The morphological and microstructural studies of the resulting biosynthesized silver nanostructures revealed that the nanostructures prepared with a small concentration of the precursor Ag salt (AgNO3 =5 mM) exhibit an ultrafine size and a narrow size distribution, whereas particles synthesized with high concentrations of the precursor Ag salt (AgNO3 =0.5 M) are polydisperse and formation of supramolecular structures occurs. Fourier transform infrared and Raman spectroscopy studies indicated that the bioreduction of the Ag- ions takes place through their interactions with free amines, carboxylate ions, and hydroxyl groups. As a consequence of such interactions, residues of proteins and polyphenols cap the biosynthesized Ag nanoparticles providing them a hybrid core/shell structure. In addition, these biosynthesized Ag nanomaterials exhibited size-dependent plasmon extinction bands and enhanced bactericidal activities against both Gram-positive and Gram-negative bacteria, displaying minimal inhibitory Ag concentrations lower than typical values reported in the literature for Ag nanoparticles, probably due to the synergy of the bactericidal activities of the Ag nanoparticle cores and their capping ligandsSEP CB12-17948

Alterations of Effective Connectivity Patterns in Mild Cognitive Impairment: An MEG Study

Producción CientíficaNeuroimaging techniques have demonstrated over the years their ability to characterize the brain abnormalities associated with different neurodegenerative diseases. Among all these techniques, magnetoencephalography (MEG) stands out by its high temporal resolution and noninvasiveness. The aim of the present study is to explore the coupling patterns of resting-state MEG activity in subjects with mild cognitive impairment (MCI). To achieve this goal, five minutes of spontaneous MEG activity were acquired with a 148- channel whole-head magnetometer from 18 MCI patients and 26 healthy controls. Interchannel relationships were investigated by means of two complementary coupling measures: coherence and Granger causality. Coherence is a classical method of functional connectivity, while Granger causality quantifies effective (or causal) connectivity. Both measures were calculated in the five conventional frequency bands: delta (d, 1-4 Hz), theta (q, 4-8 Hz), alpha (a, 8-13 Hz), beta (b, 13-30 Hz), and gamma (g, 30-45Hz). Our results showed that connectivity values were lower for MCI patients than for controls in all frequency bands. However, only Granger causality revealed statistically significant differences between groups (p-values < 0.05, FDR corrected Mann-Whitney U-test), mainly in the beta band. Our results support the role of MCI as a disconnection syndrome, which elicits early alterations in effective connectivity patterns. These findings can be helpful to identify the neural substrates involved in prodromal stages of dementia.This research was supported by ‘Ministerio de Economía y Competitividad’ and ‘European Regional Development Fund’ under project TEC2014-53196-R, by ‘European Commission’ and ‘European Regional Development Fund’ under project ‘Análisis y correlación entre el genoma completo y la actividad cerebral para la ayuda en el diagnóstico de la enfermedad de Alzheimer’ (‘Cooperation Programme Interreg V-A Spain-Portugal POCTEP 2014-2020’), and by ‘Consejería de Educación de la Junta de Castilla y León’ under project VA037U16.

Abdominal adiposity increases lordosis and doubles the risk of low back pain

Vertebral disorders have significant health and economic impacts, and due to aging and current lifestyle habits, there is a trend toward their increase. Obesity and the alignment of vertebral curvatures can be associated with back pain. Objective: This study aims to analyze whether general and abdominal obesity are associated with cervical, dorsal, and lumbar vertebral pain as well as increased or decreased values of cervical, dorsal, and lumbar vertebral curvatures. Methodology: Body composition, degree of vertebral curvature, and the perception of cervical, dorsal, and lumbar pain were evaluated in a study population of 301 people (>18 years old). Linear and logistic regression analyses were performed to evaluate the influence of several variables of body composition on vertebral angles and cervical, dorsal, and lumbar pain. Results: Lumbar pain was the most prevalent (66.1%), mainly affecting women (70.9%). They were also shown to have greater lumbar angles (p < 0.001). The degrees of lumbar curvature increased, as did the BMI, waist circumference, and waist-to-height ratio. Cervical and dorsal curvatures were increased by all the variables of adiposity and abdominal adiposity. It was found that people with abdominal obesity carried twice the risk of lower back pain than those without abdominal obesity (OR = 2.172, p < 0.05). In addition, an increased lumbar angle was related to an increased risk of low back pain (OR = 1.031, p < 0.05). Cervical pain, on the other hand, was associated with the waist-height index (OR = 0.948, p <0.01). Conclusions: This study shows that increased lumbar curvature and abdominal obesity may be risk factors for lower back pain. In addition, it shows an association between the amount of body and abdominal fat in relation to the degree of curvature of the spine in the sagittal plane. Investigating the effect of obesity on vertebral morphology and musculoskeletal disorders makes it possible to prescribe interventions and therapeutic strategie
