Scattering and absorption imaging of a highly fractured fluid-filled seismogenetic volume in a region of slow deformation

Regions of slow strain often produce swarm-like sequences, characterized by the lack of a clear mainshock-aftershock pattern. The comprehension of their underlying physical mechanisms is challenging and still debated. We used seismic recordings from the last Pollino swarm (2010–2014) and nearby to separate and map seismic scattering (from P peak-delays) and absorption (from late-time coda-wave attenuation) at different frequencies in the Pollino range and surroundings. High-scattering and high-absorption anomalies are markers of a fluid-filled fracture volume extending from SE to NW (1.5–6 Hz) across the range. With increasing frequency, these anomalies approximately cover the area where the strongest earthquakes occurred from the sixteenth century until 1998. In our interpretation, the NW fracture propagation ends where carbonates of the Lucanian Apennines begin, as marked by a high-scattering and low-absorption area. At the highest frequency (12 Hz) the anomalies widen southward in the middle of the range, consistently marking the faults active during the recent Pollino swarm. Our results suggest that fracture healing has closed small-scale fractures across the SE faults that were active in the past centuries, and that the propagation of fluids may have played a crucial role in triggering the 2010–2014 Pollino swarm. Assuming that the fluid propagation ended at the carbonates barrier in the NW direction, fractures opened new paths to the South, favoring the nucleation of the last Pollino swarm. Indeed, the recently active faults in the middle of the seismogenic volume are marked by a high-scattering and high-absorption footprints. Our work provides evidence that attenuation parameters may track shape and dynamics of fluid-filled fracture networks in fault areas.

Numerically Calculated 3D Space-Weighting Functions to Image Crustal Volcanic Structures Using Diffuse Coda Waves

Seismic coda measurements retrieve parameters linked to the physical characteristics of rock volumes illuminated by high frequency scattered waves. Space weighting functions (SWF) and kernels are different tools that model the spatial sensitivity of coda envelopes to scattering and absorption anomalies in these rock matrices, allowing coda-wave attenuation (Qcoda) imaging. This note clarifies the difference between SWF and sensitivity kernels developed for coda wave imaging. It extends the SWF previously developed in 2D to the third dimension by using radiative transfer and the diffusion equation, based on the assumption that variations of Qcoda depend solely on variations of the extinction length. When applied to active data (Deception Island, Antarctica), 3D SWF images strongly resemble 2D images, making this 3D extension redundant. On the other hand, diffusion does not efficiently model coda waveforms when using earthquake datasets spanning depths between 0 and 20 km, such as at Mount St. Helens volcano. In this setting, scattering attenuation and absorption suffer tradeoffs and cannot be separated by fitting a single seismogram energy envelope for SWF imaging. We propose that an approximate analytical 3D SWF, similar in shape to the common coda kernels used in literature, can still be used in a space weighted back-projection approach. While Qcoda is not a physical parameter of the propagation medium, its spatially-dependent modeling allows improved reconstruction of crustal-scale tectonic and geological features. It is even more efficient as a velocity independent imaging tool for magma and fluid storage when applied to deep volcanism.This research was partly supported by the Projects TEC2015-68752 (MINECO/FEDER), TEC2015-68752 (KNOWAVES)

Fluticasone furoate maintains epithelial homeostasis via leptin/leptin receptor pathway in nasal cells

Leptin is involved in the lung epithelial homeostasis. Its role in the nasal tract is largely unknown. Allergic rhinitis (AR) is induced by the allergen exposure leading to consequential structural abnormalities in the nasal epithelium. Topical corticosteroids are recommended as first-line therapy in AR. Parietaria pollen is one of the most important allergenic sources in the southern Europe. In vitro, in human nasal epithelial cell line RPMI 2650, we aimed to determine whether allergen stimulation acts on leptin/leptin receptor pathway and how fluticasone furoate (FF) influences this pathway. The effects of the major allergen recombinant Par j 1 (rPar j 1), of FF, of leptin, and of TGF-b1 on cell proliferation, on leptin/leptin receptor expression and modulation (by clonogenic test, by RT-q- RT-PCR, by immunocytochemistry and by flow-cytometry), and on STAT-3 activation (assessing nuclear translocation by western blot analysis) were assessed. We found that rPar j 1 and TGF-b1 significantly decreased cell proliferation and down-regulated the leptin/leptin receptor pathway, whereas FF and leptin reverted them, both alone and in combination. Furthermore, rPar j 1 reduced, while leptin and FF increased STAT-3 activation. In conclusion, FF and leptin itself are able to preserve nasal epithelial homeostasis restoring the leptin/leptin receptor pathway altered by rPar j 1 exposure

La participación de los grupos de interés como instrumento de responsabilidad social corportativa. El caso de las pequeñas y medianas empresas familiares

En el presente trabajo se analizan las características de la participación de los grupos de interés en las empresas pequeñas y medianas empresas familiares (PYMEF). El propósito del artículo es comprender los motivos, el sentido y el modo de participación de los grupos de interés en este tipo de empresa. La participación de los grupos de interés ha sido relacionada, a menudo, con la responsabilidad social de las empresas, afirmándose que aquellas empresas que adoptan una variedad de iniciativas para involucrar a sus grupos de interés, pueden ser descritas como socialmente responsables. Esta afirmación no es aceptable en todas las circunstancias, de modo que el problema es entender cuándo las distintas formas de participación de los grupos de interés son consistentes con el concepto de responsabilidad social corporativa. El interés en las PYMEF se justifica, por una parte, por la proporción de este tipo de empresas y por las características que las diferencian, por otra parte, por las motivaciones que llevan una PYMEF a aplicar prácticas de participación de sus grupos de interés y cómo esta aplicación puede ser diferente a la de las grandes empresas. Creemos útil reflexionar sobre las diferentes formas de participación, que pueden llevarnos a no aplicar automáticamente los mismos modelos y enfoques teóricos que utilizamos para las grandes empresas.ABSTRACTIn this paper we analyze the characteristics of stakeholder engagement in small and medium-sized family enterprises (SMFEs). The paper aims to understand the reason, the meaning and the manner to involve stakeholders in this kind of firm. The stakeholder engagement has been linked with corporate social responsibility, stating that firm that take initiatives to engage its stakeholders can be described as socially responsible. This claim is not always acceptable because we have to understand when the different forms of stakeholder engagement are consistent with the concept of corporate social responsibility. The focus in SMFEs is justified, on the one hand, for its specific characteristics and on the other hand, because in the SMEFs the reasons to implement stakeholder engagement are very different from those of larger firms. We believe useful to reflect upon the different forms of involvement because we cannot automatically apply to SMFEs the same patterns and theoretical approaches used for large firms
