An empirical study on open position risk assessment using VAR and regression analysis: A case study of Iranian banking industry

During the past few years, there have been tremendous fluctuations on different currencies. For instance, European common currency, Euro, has be fluctuated between 0.60 to 0.9 against US dollar. Therefore, it is important to study the behavior of currency valuations using different techniques. In this paper, we present an empirical study to measure the impact of different items on risk of foreign currency using value at risk (VaR) and regression methods. The proposed model of this paper investigates whether the risk of open positions of six foreign currencies including US dollar, Euro, British Pound, Switzerland Frank, Norwegian Kroner and United Emirate Dirham increase during the time horizon. The proposed study of this paper uses historical daily prices of these currencies for a fiscal year of 2011 in one of private banks located in Iran and measures the relative risk. The results of the implementation of two methods of VaR and linear regression indicate that the risk of open positions increases during the time horizon

Neurovascular coupling in the developing neonatal brain at rest

International audienceThe neonatal brain is an extremely dynamic organization undergoing essential development in terms of connectivity and function. Several functional imaging investigations of the developing brain have found neurovascular coupling (NVC) patterns that contrast with those observed in adults. These discrepancies are partly due to that NVC is still developing in the neonatal brain. To characterize the vascular response to spontaneous neuronal activations, a multiscale multimodal noninvasive approach combining simultaneous electrical, hemodynamic, and metabolic recordings has been developed for preterm infants. Our results demonstrate that the immature vascular network does not adopt a unique strategy to respond to spontaneous cortical activations. NVC takes on different forms in the same preterm infant during the same recording session in response to very similar types of neural activation. This includes (a) positive stereotyped hemodynamic responses (increases in HbO, decreases in HbR together with increases in rCBF and rCMRO2), (b) negative hemodynamic responses (increases in HbR, decreases in HbO together with decreases in rCBF and rCMRO2), and (c) Increases and decreases in both HbO-HbR and rCMRO2 together with no changes in rCBF. Age-related NVC maturation is demonstrated in preterm infants, which can contribute to a better understanding/prevention of cerebral hemodynamic risks in these infants

Why wealth inequality matters

Over the past decade, wealth inequality – driven by the private ownership of assets such as property, savings, and investments -– has increasingly been recognised as a major divisive force in the UK, and across the globe. Numerous studies have emphasised that because wealth builds over long time periods and offers huge advantages to the wealthy, it is rapidly becoming the major driver of contemporary socio-economic inequality1. These arguments are not only gaining academic currency but are also increasingly gaining public attention, notably around strategies for taxing the super-rich. More needs to be done, however, to broaden the awareness of the challenges of wealth inequality across numerous policy fields, so that the true gravity of the issues is realised
