Envy on Facebook: a hidden threat to users’ life satisfaction?

The wealth of social information presented on Facebook is astound-ing. While these affordances allow users to keep up-to-date, they also produce a basis for social comparison and envy on an unprecedented scale. Even though envy may endanger users’ life satisfaction and lead to platform avoidance, no study exists uncovering this dynamics. To close this gap, we build on responses of 584 Facebook users collected as part of two independent studies. In study 1, we explore the scale, scope, and nature of envy incidents triggered by Face-book. In study 2, the role of envy feelings is examined as a mediator between intensity of passive following on Facebook and users’ life satisfaction. Con-firming full mediation, we demonstrate that passive following exacerbates envy feelings, which decrease life satisfaction. From a provider’s perspective, our findings signal that users frequently perceive Facebook as a stressful environ-ment, which may, in the long-run, endanger platform sustainability.

Intercambio científico tecnológico : un proyecto concretado

En el marco del Programa de Cooperación Internacional con UFZ de Leipzig-Halle, Alemania y el apoyo de SECYT, UNCuyo, el CIFOT realiza (1998) el “ Atlas Socioeconómico y Demográfico de los Departamentos del Gran Mendoza" , titulado "Atlas Social de la Ciudad de Leipzig" en Alemania. Tienen como objetivo la generación de Bancos de Datos (tecnología GIS) para el análisis estadístico de indicadores seleccionados y elaboración de Cartografía base y temática. Para su elaboración se forma un equipo de trabajo interdisciplinario que apartan al sistema diferentes visiones del mismo tema. Consta de 3 partes: introducción con características de las zonas en estudio, otra parte con incorporación de mapas y una tercera que es la traducción al inglés del texto. Ambos Atlas resultaron ser elementos de gran utilidad en la planificación territorial de un área como el Gran Mendoza, de fuerte presencia frente al Mercosur, y de Liepzig, ciudad europea en transformación desde 1990.

Composition of soil samples from injection location

CO2 leakage from subsurface storage sites is one of the main concerns connected with the CCS technology. As CO2 leakages into near surface formations appear to be very unlikely within pilot CCS projects, the aim of this work is to emulate a leakage by injecting CO2 into a near surface aquifer. The two main questions pursued by the injection test are (1) to investigate the impact of CO2 on the hydrogeochemistry of the groundwater as a base for groundwater risk assessment and (2) to develop and apply monitoring methods and monitoring concepts for detecting CO2 leakages in shallow aquifers. The presented injection test is planned within the second half of 2010, as a joint project of the University of Kiel (Germany), the Helmholtz-Centre for Environmental Research (Leipzig, Germany) and the Engineering Company GICON (Dresden, Germany). The test site has been investigated in detail using geophysical methods as well as direct-push soundings, groundwater well installation and soil and groundwater analyses. The present paper presents briefly the geological and hydrogeological conditions at the test site as well as the planned injection test design and monitoring concept.
