This paper provides a survey of the existing literature on spatial panel data models. Both static and dynamic models will be considered. The paper also demonstrates that spatial econometric models that include lags of the dependent variable and of the independent variables in both space and time provide a useful tool to quantify the magnitude of direct and indirect effects, both in the short te...

This paper develops a new model and estimation procedure for panel data that allows us to identify heterogeneous structural breaks. We individual heterogeneity using grouped pattern. For each group, we allow common breaks in the coefficients. However, number, timing, size of these can differ across groups. develop hybrid fixed effects approach adaptive group fused Lasso. show our method consist...

writing as a productive skill requires practice in the basic sub-skills of vocabulary and grammar. in fact, grammar has been viewed as the core of programs in writing classes to help the students put the elements of sentence together and combine sentences of specific lengths to come up with an error-free work of art. conceptualizing l2 writing in this way introduces writing as a product and enc...

steel shear walls, like bracings are a resistance system against wind and earthquake loads, which have more advantages than other systems. this paper is investigating the influence of openings on steel shear walls under increasing static loads. for this purpose, the experiments of other researchers on finite elements method have been checked and after investigating the correctness and precision...

This article proposes an estimation approach for panel models with mixed continuous and ordered categorical outcomes based on generalized estimating equations for the mean and pseudo-score equations for the covariance parameters. A numerical study suggests that efficiency can be gained as concerns the mean parameter estimators by using individual covariance matrices in the estimating equations ...

abstract the purpose of this study is twofold: on the one hand, it is intended to see what kind of noticing-the –gap activity (teacher generated vs. learner generated) is more efficient in teaching l2 grammar in classroom language learning. on the other hand, it is an attempt to determine which approach of the noticing-the-gap- activity is more effective in the long- term retention of grammar...
