Incorporating Asymmetric and Asynchronous Evidence of Understanding in a Grounding Model
نویسندگان
چکیده
The grounding process relies on the evidence that speakers give about their understanding (Clark and Schaefer, 1989). However in existing models of grounding (Cahn, 1992; Cahn and Brennan, 1999; Traum, 1999) evidence of understanding is assumed to be symmetrically and synchronously shared by the speakers. We propose a grounding model based on (Cahn, 1992) that removes these simplifications; we do so by distinguishing the phase of interpretation from the phase of evidence extraction.

Asymmetric Behavior of Inflation in Iran: New Evidence on Inflation Persistence Using a Smooth Transition Model
T his paper investigates the asymmetric behavior of inflation. We use logistic smooth transition autoregressive (LSTAR) model to characterize the regime-switching behavior of Iran’s monthly inflation during the period May 1990 to December 2013. We find that there is a triple relationship between the inflation level, its fluctuations and persistence. The findings imply that the behavi...

Empirical studies show that there is stronger dependency between large losses than large profit in financial market, which undermine the performance of using symmetric distribution for modeling these asymmetric. That is why the assuming normal joint distribution of returns is not suitable because of considering the linier dependence, and can be lead to inappropriate estimate of VaR. Copula theo...

The article presents the transients analysis of the substation grounding systems and transmission line tower footing resistances which can affect to the back-flashover (BF) or overvoltage across insulator chain in an HV power systems by using EMTP-RV software. The related transient modeling of the grounding systems is based on a transmission line (TL) model with considering the soil ionization....
متن کاملBusiness cycles in Iran: Evidence from asymmetry and correlated shocks
In this Paper, business cycle asymmetry in Iran has been investigated using a nonlinear unobserved component model. In this regard, according to Kim and Nelsonchr('39')s (1999) interpretation of Friedman plucking model (1993), asymmetric transitory component has been modeled and simultaneously the possibility of a correlation between transitory and permanent shocks has also been considered. The...

In the past, grounding systems usually were modeled by an individual Resistor. This estimation is useful only at low frequencies, while in high frequencies, the inductance of the grounding system plays the main role to identify the phase and amplitude of that. In recent years, as wind farms grow rapidly throughout the world, the grounding system and ground impedance of wind turbine towers under...
