La emergencia del Travel Blogger. Producción de la subjetividad desde la figura laboral de la microcelebridad

El objetivo de la presente tesis apunta a vislumbrar, distinguir y comprender los elementos sociotécnicos que participan en la producción de la subjetividad que ocurre paralelamente a la figura laboral del travel blogger. Para ello, desde una perspectiva interaccionista, posestructuralista e inspirada en la teoría actor-red, se esbozó un aparato conceptual teórico destinado a facilitar el entendimiento sobre las maneras en que este tipo de microcelebridades experimentan, despliegan, articulan, mercantilizan y, sobre todo, producen una subjetivividad en relación con ciertos componentes tecnológicos y sociales. Así, desde la perspectiva de los métodos digitales, se establecieron 20 entrevistas en profundidad (en línea) a travel bloggers, promotores de turismo y seguidores con el propósito de comprender los procesos de sujeción, normalización y subjetivación que dicha persona experimenta. Por otro lado, se usó la analítica cultural para identificar los patrones en el despliegue identitario que se traza, publicación tras publicación, en los perfiles de Instagram. Finalmente, se recurrió al análisis sociométrico para distinguir a las tribus digitales que interactuaron con las publicaciones de las y los travel bloggers analizados(as). Como resultado, se encontró que el travel blogger es una expresión paradigmática de un sujeto-marca inserto en un proceso de tensiones derivadas de su relación con los seguidores, los acuerdos que establece con los promotores, la forma en que entiende los algoritmos, la manera en que experimenta los viajes y el vínculo que mantiene con las estadísticas que brinda la plataforma. Además, en otro nivel, se visibilizó cómo los participantes recurren a ciertas estrategias visuales y retóricas textuales para construir un personaje coherente, recortar el paisaje en función de sus intereses, conectar con otras comunidades, apropiarse de significados colectivos y promocionarse a partir de las normativas de visibilidad que impone la plataforma. Por último, se realizó una lectura que sugirió una comprensión respecto a cómo las publicaciones generan un vínculo con comunidades digitales que se articulan y se definen colectivamente a partir de figuras identitarias laborales insertas en la industria de la influencia (fotográfos, travel y fashion bloggers) o a través del orgullo que presentan por su lugar de origen o por su afinidad por el acto de viajar

Prediction of the transmission loss in a flexible chamber

[EN] Acoustic components have been extensively studied supposing perfectly rigid behavior. Although some works have been performed for the radiated sound in the case of a flexible element, an important lack of information exists concerning transmission loss analysis. The current investigation proposes the study for a generic flexible expansion chamber. The analysis has been performed using two different methods: a resolution in the time domain, using a Finite Volume discretization for the fluid domain and a Finite Element discretization for the solid domain, and an approach in the frequency domain, using a Finite Element discretization for both fluid and solid. After studying the rigid case in order to tune up the simulation, the study of the flexible case shows a good agreement among both methods. The comparison of rigid and flexible expansion chambers shows the importance of accounting for these phenomena when the frequency content of the acoustic signal excites the natural modes of the structure.This work has been partially supported by the Spanish Ministerio de Economia y Competitividad through Grant No. DPI2015-70464-R and Generalitat Valenciana by means of project Prometeo/2016/007.Torregrosa, AJ.; Gil, A.; García-Cuevas González, LM.; Quintero-Igeño, P.; Denia, FD.

Flash sintering of highly insulating nanostructured phase-pure BiFeO3

We show that BiFeO, that is electrically homogeneous, is a good insulator, and has a low dielectric constant (the properties desired in its applications), can be produced by flash sintering, which is nominally difficult to achieve by conventional and spark plasma sintering processes. The flash-sintered specimens had a uniform microstructure with a nanometric grain size of ~20 nm.Ministerio de Economía y Competitividad CTQ2014-52763-C2-1-RJunta de Andalucía TEP- 7858Office of Naval Research (USA) N00014-15-1-250

Inflammatory markers and bone mass in children with overweight/obesity: the role of muscular fitness

Objectives To examine which inflammatory markers are associated with bone mass and whether this association varies according to muscular fitness in children with overweight/obesity. Methods Plasma interleukin-1β (IL-1β), IL-6, tumor necrosis factor-α (TNF-α), epidermal growth factor, vascular endothelial growth factor A (VEGF), and C-reactive protein were analyzed in 55 children aged 8–11 years. A muscular fitness score was computed. Bone mineral content (BMC) of the total body-less head (TBLH) and lumbar spine (LS) were assessed using dual-energy x-ray absorptiometry. Results IL-6 (β = −0.136) and VEGF (β = −0.099) were associated with TBLH BMC, while TNF-α (β = −0.345) and IL-1β (β = 0.212) were associated with LS BMC (P < 0.05). The interaction effect of muscular fitness showed a trend in the association of VEGF with TBLH BMC (P = 0.122) and TNF-α with LS BMC (P = 0.057). Stratified analyses by muscular fitness levels showed an inverse association of VEGF with TBLH BMC (β = −0.152) and TNF-α with LS BMC (β = −0.491) in the low-fitness group, while no association was found in the high-fitness group. Conclusion IL-6, VEGF, TNF-α, and IL-1β are significantly associated with bone mass. Higher muscular fitness may attenuate the adverse effect of high VEGF and TNF-α on bone mass

Identification of arid phases during the last 50 kyr Cal BP from the Fuentillejo maar lacustrine record (Campo de Calatrava Volcanic Field, Spain).

Geochemical (element analysis, molecular analysis of organic compounds), physical, palynological, mineralogical and sedimentary facies analysis were performed to characterise the sedimentary record in Fuentillejo maar-lake in the Central Spanish Volcanic Field of Campo de Calatrava, in order to reconstruct the palaeoenvironmental and palaeoclimatic processes which controlled vegetation patterns and deposition of different sedimentary facies. The upper 20 m of core FUENT-1 show variations in clastic input, water chemistry, vegetation and organic fraction sources in the lake throughout the Late Pleistocene and Holocene. The temporal framework provided by14C accelerator mass spectrometry dating allows assigning the sequence to the last 50 cal. ka BP. Arid phases identified in the FUENT-1 sequence are correlated to Heinrich events (HE) and to stadials of the Dansgaard/Oeschger (D/O) cycles. Siliciclastic facies with high magnetic susceptibility values, high Juniperus pollen content, a low Paq index (aquatic macrophysics proxy index), a decrease in the relative percentage of the n-C27 and an increase in the n-C31 alkanes are indicative of arid and colder climatic events related to HE 2, HE 1 and the Younger Dryas (YD). Similar short cold and arid phases during the Holocene were identified at 9.2–8.6, 7.5–7 and 5.5–5 cal. ka BP. In dolomite–mud facies, the pollen data show an increase in the herbs component, mainly – Chenopodiaceae, Artemisia andEphedra – steppe taxa; a low Paq index, a decrease in the relative percentage of the n-C27 alkane and an increase in the n-C31 alkane are also observed. This facies was probably the result of lower lake levels and more saline–alkaline conditions, which can be interpreted as linked to arid–warm periods. These warm and arid phases were more frequent during Marine Isotope Stage (MIS) 3 and the interstadials of MIS 2. HE 4, HE 2, HE 1 and the YD in core FUENT-1 were immediately followed by increases of warm steppe pollen assemblages that document rapid warming similar to the D/O cycles but do not imply increasing humidity in the area. Fuentillejo hydrology is controlled by changes in the atmospheric and oceanic systems that operated on the North Atlantic region at millennial scale during the last 50 cal. ka B

Maternal imprinting on cognition markers of wild type and transgenic Alzheimer's disease model mice

The risk of suffering from Alzheimer’s disease (AD) is higher in individuals from AD-affected mothers. The purpose of this investigation was to study whether maternal transmission might produce AD-related alterations in progenies of mice that do not have any genotypic alteration. We used cognitively-intact mothers harbouring in heterozygosity the transgene for overexpressing the Swedish double mutant version of the human amyloid precursor protein (hAβPPswe). The phenotype of the offspring with or without the transgene resulting from crossing young Tg2576 females with wild-type males were compared with those of the offspring resulting from crossing wild-type females with Tg2576 males. The hAβPPswe-bearing offspring from Tg2576 mothers showed an aggravated AD-like phenotype. Remarkably, cognitive, immunohistochemical and some biochemical features displayed by Tg2576 heterozygous mice were also found in wild-type animals generated from Tg2576 females. This suggests the existence of a maternal imprinting in the wild-type offspring that confers a greater facility to launch an AD-like neurodegenerative cascade. Such progeny, lacking any mutant amyloid precursor protein, constitutes a novel model to study maternal transmission of AD and, even more important, to discover early risk markers that predispose to the development of AD
