Let $(R,fm)$ be a Gorenstein local ring and$M,N$ be two finitely generated modules over $R$. Nagel proved that if $M$ and $N$ are inthe same even liaison class, thenone has $H^i_{fm}(M)cong H^i_{fm}(N)$ for all $iIn this paper, we provide a short proof to this result.

We use high-frequency intra-day realized volatility to evaluate the relative forecasting performance of several models for the volatility of crude oil daily spot returns. Our objective is to evaluate the predictive ability of time-invariant and Markov switching GARCH models over different horizons. Using Carasco, Hu and Ploberger (2014) test for regime switching in the mean and variance of the ...

Situational interest is the positive affect and sustained attention triggered by particular contexts (Hidi & Renninger, 2006). Some studies show interesting information enhances learning while others find it hinders learning, producing the seductive detail effect. Limited evidence suggests the seductive detail effect is weakened if emotionally interesting information is relevant to main ideas. ...

The paper aims to examine the spillover of uncertainty among commodity markets using Diebold–Yilmaz approach based on forecast error variance decomposition. Next, causal impact global factors as drivers transmission between oil and other is analyzed. Our analysis suggests that a net transmitter uncertainties, this significantly increased during financial crisis 2008–2009. use linear nonlinear c...

This paper introduces a graphical method for visually presenting and exploring the results of multiple queries simultaneously. This method allows a user to visually compare multiple query result sets, explore various combinations among the query result sets, and identify the “best” matches for combinations of multiple independent queries. This approach might also help users explore methods for ...
