Liquidity, the ease of trading an asset, strongly varies between di erent sizes of stock positions. We analyze this aspect using the Xetra Liquidity Measure (XLM), which calculates daily, weighted spread for impatient traders transacting against the limit order book.

We derive an expression for the anomalous viscosity in an anisotropically expanding quark-gluon-plasma, which arises from interactions of thermal partons with dynamically generated color fields. The anomalous viscosity dominates over the collisional viscosity for large velocity gradients or weak coupling. This effect may provide an explanation for the apparent “nearly perfect” liquidity of the ...

Evaluating suicide prevention activities is a complex task, and in a prison environment, the complexity increases when an effort is made to determine who is responsible for the suicide the individual or the prison system. This is assuming that the prison system, in itself generates suicide and is primarily responsible.(1) Although the system is not blameless, it is not necessarily a causal fact...

Furthermore, comparatively quite limited number of such studies is done in authentic classroom contexts. The present study inquired into the eff...
