Looking over the channel: The balance of media coverage about the “refugee crisis” in Germany and the UK
2022
Abstract This study compares the balance of newspaper and television news coverage about migration in two countries that were differently affected by the so-called “refugee crisis” in 2015 in terms of the geopolitical involvement and numbers of migrants being admitted. Based on a broad consensus among political elites, Germany left its borders open and received about one million migrants mainly from Syria during 2015. In contrast, the conservative British government was heavily attacked by oppositional parties for closing Britain’s borders and, thus, restricting immigration. These different initial situations led to remarkable differences between the news coverage in both countries. In line…
Community Resilience in Crises : Technology and Social Media Enablers
2014
Technology can contribute greatly to disaster resilience, especially by enhancing the interconnectedness between the authorities and the public and by facilitating the rapid exchange of information. This special issue of Human Technology: An Interdisciplinary Journal on Humans in ICT Environments is focused on technology and social media enablers of community resilience. Crises take on a variety of shapes and forms—natural or health disasters, terroristic and criminal acts, technology malfunctions, and large-scale accidents—at the local, regional, national, and global levels. Crisis management plans, created and implemented at the organizational level, typically involve public service and i…
Learning Automata-based Misinformation Mitigation via Hawkes Processes
2021
AbstractMitigating misinformation on social media is an unresolved challenge, particularly because of the complexity of information dissemination. To this end, Multivariate Hawkes Processes (MHP) have become a fundamental tool because they model social network dynamics, which facilitates execution and evaluation of mitigation policies. In this paper, we propose a novel light-weight intervention-based misinformation mitigation framework using decentralized Learning Automata (LA) to control the MHP. Each automaton is associated with a single user and learns to what degree that user should be involved in the mitigation strategy by interacting with a corresponding MHP, and performing a joint ra…
Fronteras por definir, descontento creciente, alianzas inestables y amenazas externas: la Unión Europea y su tormenta perfecta
2018
espanolLa Union Europea se halla en una crisis existencial tan evidente que incluso politicos y analistas con antecedentes ideologicos diametralmente opues-tos han acabado coincidiendo en su diagnostico, y en la necesidad urgente de una terapia de choque que detenga lo que parece una carrera hacia la destruccion del proyecto europeo. El proposito del presente ensayo es pasar revista —aun al precio de tener que ser extraordinariamente sintetico en su abordaje— a los problemas que han sumido a la Union Europea en la mas grave crisis de su ya larga historia. Problemas que en todo caso son susceptibles de agruparse en cuatro grandes rubros: los que han ralentizado y hasta invertido el proceso d…
Information Abstraction from Crises Related Tweets Using Recurrent Neural Network
2016
Social media has become an important open communication medium during crises. The information shared about a crisis in social media is massive, complex, informal and heterogeneous, which makes extracting useful information a difficult task. This paper presents a first step towards an approach for information extraction from large Twitter data. In brief, we propose a Recurrent Neural Network based model for text generation able to produce a unique text capturing the general consensus of a large collection of twitter messages. The generated text is able to capture information about different crises from tens of thousand of tweets summarized only in a 2000 characters text.
Measuring Behavior in the Home Cage: Study Design, Applications, Challenges, and Perspectives
2021
Contains fulltext : 239279.pdf (Publisher’s version ) (Open Access) The reproducibility crisis (or replication crisis) in biomedical research is a particularly existential and under-addressed issue in the field of behavioral neuroscience, where, in spite of efforts to standardize testing and assay protocols, several known and unknown sources of confounding environmental factors add to variance. Human interference is a major contributor to variability both within and across laboratories, as well as novelty-induced anxiety. Attempts to reduce human interference and to measure more "natural" behaviors in subjects has led to the development of automated home-cage monitoring systems. These syste…
Architecture of High Fidelity Simulation Tool for Crisis Management Training
2018
This paper addresses an ongoing project KriseSIM aiming at creating a virtual training tool for crisis management that should be realistic, flexible, scalable with highfidelity system architecture and user interface. Our goal is to accomplish high-level requirements developed through a codesign process with the crisis management stakeholders. In this paper, we describe a highfidelity training tool architecture, which follows the serious game design principles. The tool is designed as a resource management serious game genre, where the players will deal with limited resources and should respond based on various critical information flows. A preliminary result, i.e. the architecture and the t…
Crisis communication, anticipated food scarcity, and food preferences: Preregistered evidence of the insurance hypothesis
2021
Abstract Whereas large-scale consumption of energy-dense foods contributes to climate change, we investigated whether exposure to climate change-induced food scarcity affects preferences toward these foods. Humans’ current psychological mechanisms have developed in their ancestral evolutionary past to respond to immediate threats and opportunities. Consequently, these mechanisms may not distinguish between cues to actual food scarcity and cues to food scarcity distant in time and space. Drawing on the insurance hypothesis, which postulates that humans should respond to environmental cues to food scarcity through increased energy consumption, we predicted that exposing participants to climat…
Inequality and economic growth across countries of the Eurozone
2018
The EU economic recovery after the financial crisis is being accompanied by sluggish and unsteady growth with high levels of inequality. The relationship between income inequality and the rate of economic growth still remains a controversial issue with discrepancies in the results reported in many empirical and theoretical studies of growth and development. We explore the impact of income inequality, poverty, and wealth on the rate of economic growth in the Eurozone. We find that the effect of income inequality on economic growth is statistically insignificant, whereas poverty and savings have a negative, statistically significant effect on growth, while the effect of financial assets is po…
Effects of the Italian financial crisis on the photovoltaic dissemination in a southern city
2013
Abstract The aim of this paper is to estimate how the profitability of grid-connected PV (photovoltaic) systems may vary month by month due to the changes in all parameters involved in the economic evaluation (discount rate, PV electricity selling price, inflation rate, price of PV devices etc.). The effects of these variations were investigated for a district of a city in the South Italy (Palermo). The results of the analysis provided the trend of the actual coverage of the district power demand from June 2010 to August 2012. In particular the load match index, which considers the daily energy demand covered by PV systems, ranged from almost 30% to less than 12%, which is less than the val…
