In order to improve our intuitive understanding of the complex dynamics in human economy, sociology and the life sciences, a depository of games and educational simulations is being expanded at http://www.bcv.cee.usb.ve/juegos.php (a special multilingual website sponsored by the Central Bank of Venezuela and the University Simon Bolivar). Links to appropriate resources, submission of new material to the site, and suggestions and recommendations for its improvement are requested. The website will serve, among others, UNESCO-Unitwin-CD-DC educational activities. Contact email@example.com

Acts of terror promote economic uncertainty and financial anxiety in people, who instinctively react by reducing spending. A mere 5 percent reduction in personal consumption brought by fear of terrorism is enough to push the U.S. economy into the next recession by lowering Gross Domestic Product (GDP) by 3.5 percent. Acts of terror promote economic uncertainty and financial anxiety in people, who instinctively react by reducing spending. A 5 percent reduction in personal consumption, which makes up nearly 70 percent of the U.S. economy, will decrease Gross Domestic Product (GDP) by 3.5 percent or negative 1.4 percent based on the 2015 third quarter GDP of 2.1 percent. Terrorism impacts the economy in two distinct ways. The first is the immediate impact on commerce right after a terror attack. The November 2015 terror attack in Paris de facto paralyzed commerce in parts of Paris, and later on in the entire city of Brussels in Belgium, for a few days. Repeated economic disruptions like these can have severe economic impact on local and national economies.
We experimented with every aspect of making coffee. What we found surprised us.
Over here at Decision Science News, we like Engineering All The Things. Accordingly, in an obsessive coffee phase, we acquired: A Coffee Maker that lets us set the exact brewing temperature A Digital Thermometer that lets us measure drinking temperature A Digital Scale that lets us weigh the grams A Coffee Grinder that lets us set the coarseness of the grind If you want to experiment, knock yourself out. What the figure above shows is that something around 55 grams of coffee per liter of water is considered ideal, but you can play around in the 50 to 65 grams / liter range. It’s harder to set where you want to be on the red lines without expensive equipment, but generally as you grind the coffee finer and brew longer you move up and to the right.
Textual data from analysts’ reports to blog posts can help banks enhance their credit-risk models.
Most banks use credit-rating models to help them make decisions about lending to companies. Such models are indeed a requirement for banks using Basel II’s internal-ratings-based approach. But these models often have significant shortcomings. First, they are frequently backward-looking. Second, they rely on borrowers’ formal financial reporting, which means that data are always at least 6 months old; toward the end of the fiscal year, data are nearly 18 months old. Third, qualitative assessments of borrowers are often simplistic. And finally, many banks rely on their credit-rating models to provide both a current snapshot and a longer-term view, with the result that they do neither well. Textual information can help banks overcome some of these challenges and improve their credit-risk assessment, in particular their approach to qualitative assessment. This information includes professionally produced content such as analysts’ reports and business journalism, as well as informal texts such as blogs and posts on social networks. Compared with the financial information available about small and midsize enterprises (SMEs) or corporates, the amount of textual content about companies is immense and provides a wealth of information. News articles describe the latest developments of companies; analysts’ reports provide insightful analyses on companies’ strategies, competitive positioning, and outlook; product ratings on online-shopping sites provide unfiltered views of customer satisfaction; and microblogs such as Twitter distribute the latest news (and sometimes gossip) with unprecedented speed.
