Recent physiological studies have implicated theta - a high-amplitude 4-8 Hz oscillation that is prominent in rat hippocampus during locomotion, orienting and other voluntary behaviors - in synaptic plasticity, information coding and the function of working memory. Intracranial recordings from human cortex have revealed evidence of high-amplitude theta oscillations throughout the brain, includi...

Abstract The main objective of this study was to examine the relationship between Value at Risk (VaR) and expected returns from 2002 to 2013 in Tehran’s Stock Exchange. In this study parametric value at risk, which considers the distribution of returns as normal and the historical value at risk as abnormal, was used to test the presence of the volatility anomaly in the companies listed i...

In a recent randomized experiment we found mean returns to capital of 5.7 percent per month amongst Sri Lankan microenterprises, much higher than market interest rates. In this paper we show that this high average effect masks dramatically different returns by gender. While the average male microenterprise owner has returns in excess of 9 percent per month, we show here that average returns are...

Donkey flesh is a popular food in China. To ensure the quality of donkey products plays a vital role in protecting the interests of consumers. Pork and horse are potential in donkey flesh food because of their easier availability at cheaper prices. In present study, PCR-RFLP-DHPLC technology was established for distinguishing the pork, horseflesh and donkey flesh in donkey flesh food. The assay...

in this research the asymmetric and non-linear correlation between the market returns and trading volume variables has modeled with the dcc-garch approach; and the impacts of market shocks, weekend and calendar effects on the market returns and trading volume are surveyed. the estimation results of parameters of the model by the maximum likelihood method show that previous day’s market return h...

In two visual word eye tracking studies, we investigated the influence of prosody and case marking on children’s and adults’ thematic role assignment. We assigned an SVO/ OVS-biasing (vs. neutral) prosodic contour to unambiguously case marked German subject-verb-object (SVO) and object-verb-subject (OVS) sentences respectively. Scenes depicted ambiguous action events (e.g., donkey-paints->eleph...
