Sharenting is becoming a regular practice that compromises children’s safety and privacy. This phenomenon is related to the act of sharing images of underage children on the Internet by their relatives. At the same time, a concern arises about the levels of Internet addiction in the population. In turn, levels of Internet addiction are a current problem in modern societies that has been linked to low self-control. This paper aims to analyse the degree to which images are published and the reasons why the adult segment of the population practices sharenting, to determine the socio-demographic factors that have an impact on sharenting, Internet addiction and self-control, and to establish the correlations between these three variables. A total of 367 Spanish adults aged between 18 and 61 (M=28.98; SD=10.47) completed an online survey. Both the multiple regression analysis and the structural equation modelling revealed that: 1) Age emerges as a predictor of Internet addiction; 2) Age, gender and employment status are predictors of low self-control; 3) No socio-demographic factors were found to be predictors of sharenting; 4) The only significant correlation was observed between Internet addiction and self-control. Finally, practical implications of this paper on the protection of minors and adults’ need for information on Internet security are discussed.
El sharenting se está convirtiendo en una práctica habitual que pone en riesgo la seguridad y privacidad de los niños. Este fenómeno responde al acto de compartir imágenes de menores de edad en Internet por parte de los familiares. A su vez, los niveles de adicción a Internet son una problemática actual en las sociedades modernas que ha empezado a vincularse con tener un bajo autocontrol. El objetivo de este estudio fue analizar el grado de publicación de imágenes y los motivos para realizar sharenting por parte de la población adulta, determinar los factores sociodemográficos que influyen en el sharenting, la adicción a Internet y autocontrol y establecer las correlaciones generadas entre estas tres variables. Participaron en la encuesta en línea un total de 367 adultos españoles entre 18 y 61 años (M=28,98; SD=10,47). Los análisis de regresión múltiple y el modelado de ecuaciones estructurales revelaron que: 1) La edad se alza como un predictor de la adicción a Internet; 2) La edad, género y situación laboral son predictores de un bajo autocontrol; 3) No se hallaron factores sociodemográficos que sean predictores del sharenting; 4) La única correlación significativa se estableció entre la adicción a Internet y el autocontrol. Finalmente, se discuten las implicaciones prácticas de este trabajo sobre la protección del menor y la necesidad de formación que tienen los adultos sobre seguridad en Internet.

Published: April 2020

InContext is a custom-designed mobile application for writing assignments intended for university students in journalism and research methodology courses. In these disciplines, it has been observed that there is a need for an educational and technological tool to guide the writing of text using preloaded templates in which students can input text and multimedia material to create articles or write research reports. Besides its ease of use, the app was intended to improve metacognitive thinking. This led to the establishment of six working hypotheses in an exploratory study. For the study, a random sample of students enrolled in the aforementioned courses was selected during the August-December 2019 semester at a private university in Mexico. They took a pre-test using the “Motivated Strategies for Learning Questionnaire” (MSLQ) that had been translated into Spanish and already validated in Mexico. Subsequently, the students used the application and then answered the same questionnaire as a post-test. The study aimed to compare the results of the tests to see whether there was an improvement in cognitive skills. The results showed an increase in four skills: critical thinking, data search, cognitive self-regulation, and regulation of effort. The research results did indicate metacognitive development that would benefit the academic and professional work of future graduates.InContext es una aplicación móvil, diseñada a medida, para elaborar trabajos de redacción para estudiantes universitarios de los cursos de periodismo y de metodología de la investigación. En estas disciplinas se observó que había una necesidad de contar con una herramienta educativa y tecnológica que guiara la redacción utilizando plantillas precargadas en las cuales los estudiantes pudieran agregar texto y material multimedia para con ello construir artículos periodísticos o reportes de investigación. Además de la facilidad de uso, se esperaba que la app mejorara el pensamiento metacognitivo, por lo cual se establecieron seis hipótesis de trabajo en un estudio exploratorio. Para la investigación se seleccionó una muestra aleatoria de estudiantes inscritos en los cursos durante el semestre agosto-diciembre 2019 en una universidad privada de México. Los alumnos realizaron un pretest utilizando el cuestionario Motivated Strategies for Learning Questionnaire (MSLQ) traducido al español y ya validado en México; posteriormente utilizaron la aplicación y contestaron el mismo cuestionario a manera de postest, con el objetivo de comparar si había una mejora en las habilidades cognitivas. Los resultados indican que existe un aumento en cuatro habilidades: pensamiento crítico, búsqueda de datos, autorregulación cognitiva y regulación del esfuerzo, pero no lo hubo en organización ni en búsqueda de ayuda. Estos resultados indican un desarrollo metacognitivo que beneficia el trabajo académico y profesional de los futuros egresados.
La vie bienheureuse comme tâche de l’architecture
Authors: Lohmann Petra , Quétier Jean 
Published: April 2020

L’éducation à la vie, entendue en son sens le plus haut comme libre réalisation de soi, constitue la finalité constante de l’œuvre philosophique de Fichte. Au sens spéculatif, Fichte combine le concept d’image et la possibilité de proposer des visions du futur dans lesquelles l’image idéale ne vise pas à dépeindre la réalité, mais à l’inverse représente le futur. La transcription de ces images ou idées dans la réalité ne saurait s’effectuer qu’au moyen de l’art, offrant ainsi une vision sensuelle de l’idée de la vie immédiate. Cet article cherche avant tout à étendre cette idée bien connue des recherches fichtéennes au discours du philosophe sur l’architecture comprise comme un « symbole de la vie ».
Violence(s) : le printemps chilien ou cette chair coût de l’espérance
Authors: Morales La Mura Raúl , Galloro Piero-D. 
Published: April 2020

Les derniers mois de 2019 ont vu l’émergence d’une forte mobilisation sociale au Chili, celle-ci ayant pour particularité la volonté explicite de participer à l’écriture d’une nouvelle société. Cette contestation, menée essentiellement par la société civile, est la cristallisation de 30 ans de combats contre le modèle économique, social et institutionnel légué par la dictature militaire et seulement amendé par la société politique. Aussi, lors des manifestations, la violence physique mettra en évidence la violence symbolique du système dominant, soit par ceux des manifestants qui désormais la refusent, soit par ceux dont le ministère est de la préserver.
« Dissimuler » une créance au XIII e siècle : les opérations financières de Renier Acorre en Champagne
Authors: Lacomme Thomas 
Published: April 2020

Renier Acorre, originaire de Florence, est connu pour son parcours politique à la cour des comtes de Champagne puis à celle des rois de France, puisqu’il fut chambellan des comtes (1270-1278), panetier des rois (1277-1287) et receveur de Champagne (1271-1292). Ses activités de crédit, pourtant importantes et protéiformes, ont pour l’instant été peu étudiées. La plupart de ses opérations financières furent « dissimulées » dans des actes de vente, d’achat ou de donations et prirent la forme de constitutions de rentes, de dons en guise de remboursements, d’achats sans prix, de ventes avec amoisonnement, de ventes à réméré ou d’achats fictifs. Pourquoi une dette doit-elle être « dissimulée » au xiii e siècle ? L’est-elle vraiment ou s’agit-il seulement d’une question d’efficacité de l’acte ou de technicité notariale ? Pourquoi Renier Acorre choisit-il tel procédé plutôt que tel autre pour « dissimuler » ses activités bancaires ? Si ces trois questions sont évoquées, l’article traite avant tout du mécanisme des opérations de prêt derrière la rhétorique des actes notariés et de l’identité des débiteurs du Florentin.
Entre l’homme obligé et l’homme capable : la responsabilité de l’entrepreneur social. Éléments de réflexion phénoménologique
Authors: d'Hombres Emmanuel , Chabanet Didier 
Published: April 2020

L’entreprenariat social nous engage dans deux formes de responsabilité, l’une obligataire, qui ressortit au registre juridique et moral, l’autre mondaine ou cosmologique, qui ressortit au registre de l’action et de la création. La pratique entrepreneuriale en tant que telle honore prioritairement la responsabilité cosmologique, tandis que la dimension sociale de cette pratique réfère, quant à elle, au caractère obligataire. Dans cet article, nous proposons de revenir sur la généalogie de ces deux acceptions fondamentales de la responsabilité, qui ont trouvé dans le kantisme à la fois leur lieu de formulation philosophique et leur point de bifurcation, mais aussi de dégager la portée et les limites de leur dialectisation dans l’activité sociale-entrepreneuriale aujourd’hui. Nous montrons que la première convoque en son sein plusieurs traditions de philosophie morale impliquant différentes extensions du concept, ce qui oblige à nous interroger sur sa propre opérabilité. La seconde, que nous aurons à cœur d’illustrer en rapportant certains discours d’entrepreneurs, a été davantage honorée à l’époque contemporaine par les approches phénoménologiques et de philosophie de l’action de tendance analytique. Nous terminons en envisageant la possibilité pour l’entrepreneur social de s’extraire de cet atermoiement entre deux formes de responsabilité dans le contexte actuel, naguère anticipé par Hans Jonas et dont témoignent aujourd’hui le succès des thèmes de l’écologie politique et du développement durable, opérant ainsi un renversement du rapport de l’action humaine à la peur de l’avenir – peur à laquelle s’est substituée au fil du temps la projection raisonnée d’un futur malheureux, toutes choses égales ailleurs.

À propos des fondements éthiques de la critique du capitalisme par Marx
Authors: Tarrit Fabien 
Published: April 2020

La présente contribution interroge le rapport de la théorie de Marx aux problématiques en termes de justice sociale. Nous proposons une interprétation selon laquelle une théorie de la justice en soi est inutile car idéaliste. Nous la confrontons à une lecture qui implique qu’une critique du capitalisme fondée sur des critères de justice est nécessaire afin d’éviter l’écueil économiste niant l’individualité.

Published: April 2020

This report provides the new record of the sponge Radiospongilla inesi and the slug Omalonyx matheroni for the Vale do Paraiba, State of São Paulo, southeastern Brazil, besides the symbiosis among R. inesi and individuals of some benthic macroinvertebrates. Monthly collections were carried out in the Ribeirão dos Mottas, with a 0.5 cm sieve in the edge vegetation, as well as collections by hand. Three specimens of R. inesi were found, from a lotic environment under pebbles. In addition, individuals of four insect families, Sisyridae, Hydropsychidae, Chironomidae e Simuliidae, were found on the sponge aquiferous system. Six individuals of the semi-aquatic slug O. matheroni were also caught under rocks and cans. Despite the sponges are commonly found in the most of the environments, the freshwater species represents one of the most unknown animal groups of the world. R. inesi was report at first time in Brazil in Pernambuco State, northeastern Brazil region, and this report represents just the second record of this species in Brazil, and the first time to the southeastern region. The presence of individuals of four insect families pointing out the importance of R. inesi on the life history of these animals. Despite some records of Omalonix sp. to the São Paulo State, this report seems to be the first record of the O. matheroni to the Vale do Paraíba, northern of the São Paulo State.

Abstract. Heterogeneous reactivity of N2O5 on aerosols is
a critical parameter in assessing NOx fate, nitrate production, and
particulate chloride activation. Accurate measurement of its uptake
coefficient (γN2O5) and representation in air quality models
are challenging, especially in the polluted environment. With an in situ
aerosol flow-tube system, the γN2O5 was directly measured on
ambient aerosols at two rural sites in northern and southern China. The
results were analyzed together with the γN2O5 derived from
previous field studies in China to obtain a holistic picture of
N2O5 uptake and the influencing factors under various climatic and
chemical conditions. The field-derived or measured γN2O5 was
generally promoted by the aerosol water content and suppressed by particle
nitrate. Significant discrepancies were found between the measured γN2O5 and that estimated from laboratory-determined parameterizations.
An observation-based empirical parameterization was derived in the present
work, which better reproduced the mean value and variability of the observed
γN2O5. Incorporating this new parameterization into a regional
air quality model (WRF-CMAQ) has improved the simulation of N2O5,
nitrogen oxides, and secondary nitrate in the polluted regions of China.
Satellite mapping of PM2.5 episodes in the wintertime San Joaquin Valley: a “static” model using column water vapor
Authors: Chatfield Robert B. , Sorek-Hamer Meytar , Esswein Robert F. , Lyapustin Alexei 
Published: April 2020

Abstract. The use of satellite aerosol optical thickness (AOT) from imaging
spectrometers has been successful in quantifying and mapping high-PM2.5
(particulate matter with a mass <2.5 µm diameter) episodes for
pollution abatement and health studies. However, some regions have high
PM2.5 but poor estimation success. The challenges in using AOT
from imaging spectrometers to characterize PM2.5 worldwide
was especially evident in the wintertime San Joaquin Valley (SJV). The SJV's
attendant difficulties of high-albedo surfaces and very shallow, variable
vertical mixing also occur in other significantly polluted regions around
the world. We report on more accurate PM2.5 maps (where cloudiness permits)
for the whole winter period in the SJV (19 November 2012–18 February 2013).
Intensive measurements by including NASA aircraft were made for several
weeks in that winter, the DISCOVER-AQ (Deriving
Information on Surface Conditions from COlumn and VERtically Resolved
Observations Relevant to Air Quality) California mission. We found success with a relatively simple method based on calibration and
checking with surface monitors and a characterization of vertical mixing,
and incorporating specific understanding of the region's climatology. We
estimate PM2.5 to within ∼7 µg m−3
root mean square error (RMSE) and with R values of ∼0.9, based
on remotely sensed multi-angle implementation of atmospheric
correction (MAIAC) observations, and certain further work will improve that
accuracy. Mapping is at 1 km resolution. This allows a time sequence of
mapped aerosols at 1 km for cloud-free days. We describe our technique as a
“static estimation.” Estimation procedures like this one, not dependent on
well-mapped source strengths or on transport error, should help full
source-driven simulations by deconstructing processes. They also provide a
rapid method to create a long-term climatology. Essential features of the technique are (a) daily calibration of the AOT to
PM2.5 using available surface monitors, and (b) characterization of
mixed layer dilution using column water vapor (CWV, otherwise “precipitable
water”). We noted that on multi-day timescales both water vapor and
particles share near-surface sources and both fall to very low values with
altitude; indeed, both are largely removed by precipitation. The existence
of layers of H2O or aerosol not within the mixed layer adds complexity,
but mixed-effects statistical regression captures essential proportionality
of PM2.5 and the ratio variable (AOT ∕ CWV). Accuracy is much higher than
previous statistical models and can be extended to the whole Aqua satellite
data record. The maps and time series we show suggest a repeated pattern for
large valleys like the SJV – progressive stabilization of the mixing
height after frontal passages: PM2.5 is somewhat more determined by
day-by-day changes in mixing than it is by the progressive accumulation of
pollutants (revealed as increasing AOT).
A proposed method for estimating interception from near-surface soil moisture response
Authors: Acharya Subodh , McLaughlin Daniel , Kaplan David , Cohen Matthew J. 
Published: April 2020

Abstract. Interception is the storage and subsequent evaporation of rainfall by
above-ground structures, including canopy and groundcover vegetation and
surface litter. Accurately quantifying interception is critical for
understanding how ecosystems partition incoming precipitation, but it is
difficult and costly to measure, leading most studies to rely on modeled
interception estimates. Moreover, forest interception estimates typically
focus only on canopy storage, despite the potential for substantial
interception by groundcover vegetation and surface litter. In this study, we developed an approach to quantify “total” interception (i.e., including forest canopy, understory, and surface litter layers) using measurements of shallow soil moisture dynamics during rainfall events. Across 34 pine and mixed forest stands in Florida (USA), we used soil moisture and precipitation (P) data to estimate interception storage capacity (βs), a parameter required to estimate total annual interception (Ia) relative to P. Estimated values for βs(mean βs=0.30 cm; 0.01≤βs≤0.62 cm) and Ia∕P (mean Ia/P=0.14; 0.06≤Ia/P≤0.21) were broadly consistent with reported literature values for these ecosystems and were significantly predicted by forest structural attributes (leaf area index and percent ground cover) as well as other site variables (e.g., water table depth). The best-fit model was dominated by LAI and explained nearly
80 % of observed βs variation. These results suggest that
whole-forest interception can be estimated using near-surface soil moisture
time series, though additional direct comparisons would further support this assertion. Additionally, variability in interception across a single forest type underscores the need for expanded empirical measurement. Potential cost savings and logistical advantages of this proposed method relative to conventional, labor-intensive interception measurements may improve empirical estimation of this critical water budget element.
Unprecedented atmospheric conditions (1948–2019) drive the 2019 exceptional melting season over the Greenland ice sheet
Authors: Tedesco Marco , Fettweis Xavier 
Published: April 2020

Abstract. Understanding the role of atmospheric circulation anomalies on the surface
mass balance of the Greenland ice sheet (GrIS) is fundamental for improving
estimates of its current and future contributions to sea level rise. Here,
we show, using a combination of remote sensing observations, regional
climate model outputs, reanalysis data, and artificial neural networks, that
unprecedented atmospheric conditions (1948–2019) occurring in the summer
of 2019 over Greenland promoted new record or close-to-record values of
surface
mass balance (SMB), runoff, and snowfall. Specifically, runoff in 2019 ranked second within
the 1948–2019 period (after 2012) and first in terms of surface mass
balance negative anomaly for the hydrological year 1 September 2018–31 August 2019. The summer of 2019 was characterized by an exceptional
persistence of anticyclonic conditions that, in conjunction with low albedo
associated with reduced snowfall in summer, enhanced the melt–albedo
feedback by promoting the absorption of solar radiation and favored
advection of warm, moist air along the western portion of the ice sheet
towards the north, where the surface melt has been the highest since 1948.
The analysis of the frequency of daily 500 hPa geopotential heights obtained
from artificial neural networks shows that the total number of days with the
five most frequent atmospheric patterns that characterized the summer of
2019 was 5 standard deviations above the 1981–2010 mean, confirming the
exceptional nature of the 2019 season over Greenland.

La tecnología del podcasting ha conocido un considerable crecimiento durante estos últimos años, facilitada por circunstancias como la consolidación de la web semántica manual o web 2.0 y el surgimiento de la figura del prosumidor de contenidos. Desde el punto de vista de su evolución en el tiempo consideramos la existencia de cuatro etapas diferenciadas, a las que denominamos como experimental (finales del siglo XX a 2005), de consolidación (2006 a 2009), multimedia (2010 a 2013) y de eclosión (2014 hasta la actualidad). Se analiza cuál es el grado de utilización de los podcasts para el tratamiento de la temática referida a la difusión del patrimonio cultural en el ámbito específico hispanoparlante. Para ello, se ha examinado la presencia de esta clase de herramientas en dos de las principales plataformas de podcasting a escala internacional: iVoox y SoundCloud.

From the point of view of its chronological evolution, we consider the existence of four differentiated stages, which we call as experimental (late 20th century to 2005), consolidation (2006 to 2009), multimedia (2010 to 2013) and hatching (2014 to nowadays). We analyze the degree of use of podcasts for the treatment of the theme related to the dissemination of cultural heritage in the specific Hispanic-speaking environment. In order to do so, we have examined the presence of this kind of tools in two of the main international podcasting platforms: iVoox and SoundCloud.
