In developing countries, weak institutional quality can increase the probability of applying discretionary policies and can have a great impact on their double-digit inflation. Surico (2008) calculated inflation bias, but he considered just monetary policy and he did not pay attention to the institutions. Therefore, we design a model which considers the discretion in monetary and fiscal policie...
afinite element model of a bias truck tire under static vertical load using a global/local technique is designed in two parts. in the first part a previously created model for radial tires is developed to take the constructional variables of bias tires into account. it is shown that the technique can successfully be used for bias tires. the main challenge here is the selection of the initial la...
In this study, precipitation simulated annual and seasonal in East and North-East of Iran ,in 1987-2011, by using RegCM4 dynamic model in two case; with and without using post-processing technique. The required data for RegCM4 model with NetCDf format, received from ICTP center. For the implementation of the main dynamic model, Convective precipitation test scheme and the horizontal resolution,...
probabilistic approach of traffic assignment has been primarily developed to provide a more realistic and flexible theoretical framework to represent traveler’s route choice behavior in a transportation network. the problem of path overlapping in network modelling has been one of the main issues to be tackled. due to its flexible covariance structure, probit model can adequately address the pro...
This study was done to simulate runoff of Gorgan city using of the hydrologic-hydraulic model SWMM. In this study, to calibrate the model, four rainfall events, were used and the speed of the corresponding runoffs in the chosen sub basin were recorded. In this study, NS, RMSE and BIAS% were used as model performance indices in the estimating peak discharge and flow volume. Also significant and ...
williams, watts, macleod and mathews' (1988) model of anxiety and depression leads to the prediction that anxious patients will show mood – congreuent implicit memory bias, while depressed patients will show mood-congruent explicit memory bias.although this prediction has been supported by some researchers (denny & hunt, 1992 mathews, moog, et al , 1989 watkins, et al, 1992), the reliabili...
In this paper, four approaches are presented to the problem of fitting a linear regression model in the presence of spatially misaligned data. These approaches are plug-in method, simulation, regression calibration and maximum likelihood. In the first two approaches, with modeling the correlation between the explanatory variable, prediction of explanatory variable is determined at sites...
We introduce and axiomatically characterize a model of status quo bias in which the status quo affects choices by both changing preferences and focusing attention. The resulting Limited Attention Status Quo Bias model can explain both the finding that status quo bias is more prevalent in larger choice sets and that the introduction of a status quo can change choices between non-status quo alter...
Sensitive questions about people’s behaviors are often discussed in studies in the fields of human, social, and medical sciences. Obtaining valid answers to these kinds of questions is one of the main challenges in the mentioned studies. The most important risk factors for the validity of these studies are response bias and non-response bias, which occur because of concerns about divulging pe...
