The likelihood of a crash or crash potential is significantly affected by short-term turbulence of traffic flow. For this reason, crash potential must be estimated on a real-time basis by monitoring the current traffic condition. In this regard, a probabilistic real-time crash prediction model relating crash potential to various traffic flow characteristics which lead to crash occurrence, or “c...

We study consequences of regulatory interventions in limit order markets that aim at stabilizing the market after an occurrence of a "flash crash". We use a simulation platform that creates random arrivals of trade orders, that allows us to analyze subtle features of liquidity and price variability under various market structures. The simulations are performed under continuous double-auction mi...

The rare species Lymnastis novikovi Michailov, 1998, described from the single female specimen collected in Ukraine, is redescribed on the basis of new material. We provide the illustrations of the general habitus, the median lobe and its internal sac and describe the habitat of L. novikovi, to increase information about this species. A key to European Lyinastis species is given. The current di...

Of the remaining 224 publications, 30 were excluded as they were published in a language other than English, ten were excluded as they consisted of reviews or commentaries rather than cases, and an additional 16 publications were excluded as they reported on non-SVG aneurysms, the vein graft was less than 1.5 times the reference vessel, or they represented duplicate reports.

A review of the literature on the Chief Information Officer (CIO) emphasizes the importance of the role of politics in the activities of the CIO). Building on the approach established in Political Strategies Framework (Romm and Rippa, 2010) an empirical research program is described that will validate assumptions about this political role. The research will validate specific actions or attitude...
