Human conflict, geopolitical crises, terrorist attacks, and natural disasters can turn large parts of energy distribution networks offline. Europe's current gas supply network is largely dependent on deliveries from Russia and North Africa, creating vulnerabilities to social and political instabilities. During crises, less delivery may mean greater congestion, as the pipeline network is used in...

The rise of social media as communication channels has enabled customers to provide feedback or to ask for assistance quickly and easily. In the context of brand crises, the microblogging platform Twitter is highly relevant because of its ability to support information sharing. By investigating communication on Twitter, the authors examine Twitter activity patterns based on a dataset of some 24...

With the financial crises ongoing in Greece and Venezuela, sovereign debt crises have become more and more prominent in the public eye. Thus, it has become important to be able to predict when nations will enter such debt crises. We collected publicly available data in order to train models to predict, given a nation’s economic status in one year, whether they would be in a debt crisis the next...

Currency crises tend to affect countries in geographic proximity. This suggests that regional patterns of international trade are important in understanding how currency crises spread, above and beyond any macroeconomic phenomena. Using data for five different currency crises (in 1971, 1973, 1992, 1994, and 1997) we show that currency crises affect countries tied together by international trade...

Aplastic and hypoplastic crises are well recognised complications of sickle cell disease. Recent evidence has shown that most of these crises are caused by parvovirus infection. Five cases of aplastic or hypoplastic crises in patients born and living in this country were studied. Three patients had clear evidence of parvovirus infection, while in two evidence of parvovirus infection was lacking...

The paper studies mechanisms through which a sudden stop in international credit flows may bring about financial and balance of payments crises. It is shown that these crises can occur even though the current account deficit is fully financed by foreign direct investment. However, equity and long-term bond financing may shield the economy from sudden stop crises. The paper also examines possibl...

Currency crises tend to be regional; they affect countries in geographic proximity. This suggests that patterns of international trade are important in understanding how currency crises spread, above and beyond any macroeconomic phenomena. We provide empirical support for this hypothesis. Using data for five different currency crises (in 1971, 1973, 1992, 1994, and 1997) we show that currency c...

Identifying banking crises is the first step in the research on determinants of banking crises. The prevailing practice is to employ market events to identify a banking crisis. Researchers justify the usage of this method on the grounds that either direct and reliable indicators of banks’ assets quality are not available, or that withdrawals of bank deposits are no longer a part of financial cr...

Several public health crises in Europe have led to sustained outbreaks, political problems, or have generated social alarm. For this reason, a nationwide study was conducted in Spain with the objective to determine which public health events provoke the most frequent crises, to reach a consensus regarding the appropriate actions to be taken when responding to public health crises, and to provid...
