Institutions, crises, and political confidence in seven contemporary democracies. An elite-mass analysis

2017

There is ample consensus in the literature that institutional confidence by the public is needed in democracies and at the same time elites, particularly political elites, need to share this confidence in their guidance of state institutions, if political stability in established democracies and the consolidation of new democracies are desired. The research takes the form of a quantitative analysis based on the World Values Surveys and the elite surveys (parliamentarians) conducted in 2006 (before the financial crisis) and in 2012–2013 (post the crisis when apparently, the worst of the economic crunch had lessened up) in the 7 countries selected. We explore what lies at the base of politica…

Trend Switching Processes in Financial Markets

2010

For an intriguing variety of switching processes in nature, the underlying complex system abruptly changes at a specific point from one state to another in a highly discontinuous fashion. Financial market fluctuations are characterized by many abrupt switchings creating increasing trends (“bubble formation”) and decreasing trends (“bubble collapse”), on time scales ranging from macroscopic bubbles persisting for hundreds of days to microscopic bubbles persisting only for very short time scales. Our analysis is based on a German DAX Future data base containing 13,991,275 transactions recorded with a time resolution of 10− 2 s. For a parallel analysis, we use a data base of all S&P500 stocks …

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…
