The study was undertaken in six medieval-like model glass samples UG (unaltered glass), MAK, MAR, MTA, MTB and MTN subjected to various environmental and atmospheric conditions in order to generate alteration layers of different characteristics. A potash-lime silicate glass, with composition similar to that of medieval glasses, was melted at 1400 °C during two hours, poured in a brass mould of rectangular cross section and annealed at 650 °C. The resulting glass ingot was cut in slices of around 10×10×2 mm3 and then polished using emery paper and an aqueous suspension of cerium oxide to obtain optical quality surfaces. Alteration of the glass slices was conducted by exposure to five different laboratory corrosion tests: SO2 corrosion for MAK sample, synthetic river water degradation for MAR, and degradation due to acid, basic and neutral medium for MTA, MTB and MTN, respectively. This dataset consists of images of the samples; Laser-induced Breakdown Spectrocopy (LIBS) spectra; Laser-induced Fluorescence (LIF) spectra; Optical Microscopy (OM); FT-Raman spectroscopy and Multi-Photon Excitation Fluorescence (MPEF) signals obtained with a Nonlinear optical microscopy (NLOM). This information allows characterizing the composition of both body glass and determining the thickness of the degradation layer. Images are presented in JPG. All spectra are presented in cvs format, in a single page. Descriptions of the samples and the experimental conditions in which the spectra were taken and the name of the column values are included at the top of each page. For LIBS, 1 file per sample of elemental composition of the medieval-like glass are included. Each file is composed of 2 columns (wavelength and intensity). For LIF, 1 file per sample of the analysis of fluorescent species of each medieval-like glass are included. Each file is composed of 2 columns (wavelength and intensity). For NLOM, 2 files per sample. In the first one: “MPEF Safe limits”, each file is composed for 10 columns: 2 are for depth (µm) and 8 are for MPEF signal divided in two groups relating to the the power in the sample surface. In the second group of files: “MPEF profiles”, each file is composed for 4 columns: 1 is for depth (µm), 1 is the normalized MPEF intensity, 1 is the Lorentzian fit of depth (µm) and the last one Lorentzian fit. (The thicknesses of the degradation layers of the medieval-like glasses is calculated by the FWHM values of the fits after refractive index corrections). For FT-Raman, 1 file per sample of the analysis of the structure of the medieval-like glass through their vibrational modes is included. Each file is composed of 2 columns (Raman shift and intensity in arbitrary units). This dataset is subject to a Creative Commons Attribution 4.0 International (CC BY 4.0) License.

Historical glass-based objects undergo, since the time of their manufacture, different degradation phenomena that are related to their composition and to the environment to which they were exposed. Three-dimensional (3D) structural and chemical characterization of the degradation layers is important to select the most adequate conservation strategies for glass objects. Optical microscopy (OM) is the most frequently used non-destructive method to examine the surface of historical glasses; however, the 3D structural assessment of alteration layers requires applying the destructive modality of this technique to conduct a cross-sectional study. In this work, a different approach for structural and compositional characterization of alteration layers on model medieval-like glasses is presented, based on the combination of the laser spectroscopies of laser-induced breakdown spectroscopy (LIBS), laser-induced fluorescence (LIF) and FT-Raman, and the emerging, cutting edge technique of nonlinear optical microscopy (NLOM) in the modality of multiphoton excitation fluorescence (MPEF). The results obtained through this multi-analytical photonic approach were compared with those retrieved by examination of the surface and cross sections of the samples by OM and scanning electron microscopy–energy-dispersive X-ray spectroscopy (SEM–EDS). While the combination of LIBS, LIF and FT-Raman served to assess the composition of the various alteration layers, the use of MPEF microscopy allowed the non-destructive determination of the thicknesses of these layers, showing for both thickness and composition a good agreement with the OM and SEM–EDS results. Thus, the proposed approach, which avoids sample preparation, illustrates the capability of non-destructive, or micro-destructive in the case of LIBS, laser spectroscopies and microscopies for the in situ study of glass objects of historic or/and artistic value There are 4 files which correspond to each technic employed for the analysis of the six different samples. The file title “LIBS” contains: LIBS_UG; LIBS_MAK; LIBS_MAR; LIBS_MTA; LIBS_MTB; LIBS_MTN. The file for “LIF” contains: LIF_UG; LIF_MAK; LIF_MAR; LIF_MTA; LIF_MTB; LIF_MTN. The file for “FT-RAMAN” contains: FT-RAMAN_UG; FT-RAMAN_MAK; FT-RAMAN_MAR; FT-RAMAN_MTA; FT-RAMAN_MTB; FT-RAMAN_MTN. For the “MPEF” there are two files inside. One title “MPEF safe limits” which contains the documents: MPEF_MAK_SL; MPEF_MAR_SL; MPEF_MTA_SL; MPEF_MTB_SL; MPEF_MTN_SL. And the other called “MPEF profiles” which contains: MPEF_MAK_PROFILE; MPEF_MAR_PROFILE; MPEF _MTA_PROFILE; MPEF _MTB_PROFILE; MPEF _MTN_PROFILE.

This dataset contains the results of the characterisation of the prokaryotic community by flow cytometry and tritiated leucine incorporation from the MAFIA cruise (Migrants and Active Flux In the Atlantic ocean). Samples were collected in the tropical and subtropical Atlantic during the MAFIA cruise (April 2015) on board the BIO Hespérides. Seawater samples were collected at 13 stations (from the Brazilian coast to the Canary Islands), from the surface down to 3500 m, using a General Oceanics oceanographic rosette equipped with 24 l PVC Niskin bottles. Abundance and cell characteristics (high nucleic acid content fraction, cell volume, viability) were based on measurements performed with a FACSCalibur (Becton-Dickinson) flow cytometer. Leucine incorporation rates were estimated with tritiated leucine (Kirchman et al. 1985) using centrifugation and filtration methods (Smith and Azam 1992). The aim of this dataset was to estimate the influence of surface productivity on the standing stock, characteristics and activity (as leucine incorporation) of prokaryotes across the water column Horizon 2020 (H2020), grant/award no. 817806: Sustainable management of mesopelagic resources; Ministerio de Ciencia e Innovación (MICINN), grant/award no.

This article aims to analyze the use of digital communication technologies in the solidarity processes of Venezuelan migrants in Quito, Ecuador. The methodology applied was based on in-depth interviews and content analysis of WhatsApp groups. The research was conducted between June 2020 and March 2021. A non-probabilistic strategy (snowball sampling) was applied for the sampling. The results illustrate the dynamics of digital solidarity both in groups with strong ties (families) and weak ties. However, due to its qualitative nature, these results cannot be generalized. The conclusions show that in transnational families, solidarity develops from a sense of co-presence that allows the fulfillment of moral obligations, the generation of an economy of care, and emotional support. On the other hand, in the case of migrants without connective ties with each other, solidarity occurs through the construction of digital communities in large and impersonal groups.

La divulgación de información prudencial sobre los riesgos ambientales, sociales y de gobernanza (ASG) será obligatoria, a partir de junio de 2022, para las grandes empresas con valores negociados en un mercado regulado de cualquier Estado miembro. Este artículo trata de evaluar el grado de preparación de las entidades financieras europeas para este requerimiento mediante la aplicación de técnicas de minería de textos para analizar los informes prudenciales, comúnmente denominados informes de Pilar 3, correspondientes al período 2019-2020, de la mayoría de las entidades financieras significativas que están bajo la supervisión directa del BCE, con el fin de evaluar el nivel de concienciación de estas entidades en relación con la materialidad de los riesgos ASG. Al aplicar una sencilla taxonomía de términos basada en léxicos y expresiones regulares, mediante una herramienta que hemos desarrollado, somos capaces de identificar fragmentos relevantes con un alto nivel de precisión, a partir de la búsqueda de diferentes combinaciones de conceptos dentro de la taxonomía de términos. Los resultados indican que, aunque hay un mayor conocimiento de los riesgos ASG y se aprecia un aumento significativo en las instituciones más pequeñas (aquellas con activos por debajo de 30.000 millones de euros), el nivel de detalle incluido es generalmente bajo y la introducción de las nuevas divulgaciones obligatorias ASG debería tener un impacto significativo en el nivel de divulgación de información en esta área. Disclosure of prudential information on environmental, social and governance (ESG) risks will become mandatory from June, 2022 for large institutions with securities traded on a regulated market of any Member State. This paper tries to assess how prepared European financial institutions are for this requirement and applies text mining techniques to analyse the prudential reports, commonly referred to as Pillar 3 reports, for 2019 and 2020 of most of the significant banks under the ECB direct supervision in order to evaluate the level of awareness of these institutions in relation to the materiality of ESG risks. By applying a simple taxonomy of terms based on lexicons and regular expressions using a tool that we have developed, we are able to identify relevant excerpts with a high level of precision searching for different combinations of concepts within the taxonomy of terms. The results indicate that although there is an increased awareness of the ESG risks, with a significant increase in smaller institutions (those with less tan 30 billion in assets), the level of detail included is generally low and the introduction of the new ESG mandatory disclosures should have a significant impact on the level of disclosures in this area.
