Panel logit models have proved to be simple and effective tools build early warning systems (ews) for financial crises. But because crises are rare events, the estimation of ews does not usually account country-specific fixed effects, so as avoid losing all information relative countries that never face a crisis. I propose using penalized maximum likelihood estimator fixed-effects logit-based w...
The second United Nations Sustainable Development Goal (SDG2), zero hunger, aims to improve the productivity, food security, nutrition, and sustainability of small-scale farmers. fall armyworm (FAW, Spodoptera frugiperda) has been devasting smallholder farmer security since it spread sub-Saharan Africa in 2016, who have suffered massive crop losses, particularly maize, an important staple for b...
Losses due to strong seismic events can amount millions or billions of US dollars and affect regions for large periods time, even severely undermining the economy. Earthquake early warning systems have proven be helpful tools mitigate social economic impact on communities businesses. Recent case studies are briefly described, followed by examples proactive measures assets, infrastructure, citiz...
In the context of early warning systems for detecting Internet worms and other attacks, event correlation techniques are needed for two reasons. First, network attack detection is usually based on distributed sensors, e.g. intrusion detection systems. During attacks but even in normal operation, the generated amount of events is hard to handle in order to evaluate the current attack situation f...
