some researches made in the field of agency problem issue, deal with the role of control systems regarding owners and managers. in this research the relationship between the two control mechanisms, namely the voluntary disclosure (external control mechanism) and outside directors (internal control mechanism), which are reductive of agency problems, has been studied. for this reason, a sample ...
Non-oil and gas exports could be forecasted using exponential smoothing for future periods. This study examines non-oil export data in Indonesia from January 2015 to May 2021, indicating trends seasonality. Based on the characteristics, obtained were analyzed Holt's double method triple with multiplicative additives Holt-Winters. The MAPE all three models is less than 10%, that very good used f...
abstract the cr(iii) and zn(ii) complexes with 2-((9,10-dihydro-1-hydroxy-9,10-dioxaanthracen-4-yloxy)carbonyl)benzoic acid as ligand have been prepared by reacting cr(no3) and zn(no3)2 and ligand in cloroform. the cr and zn complexes with 2-((9,10-dihydro-1-hydroxy-9,10-dioxaanthracen-4-yloxy)carbonyl) were also prepared in chloroform and aceton solutions. the uv-visible and ft-ir spectra of...
Forecasting the High-Frequency Exchange Rate Volatility with Smooth Transition Exponential Smoothing
Smooth Transition Exponential Smoothing (STES) is a popular exponential smoothing method for volatility forecasting; whereby the success of STES model lies in choice transition variable. In this paper, three realized variance (RV), daily, weekly and monthly RV were used as variables methods to evaluate performance intraday data. While daily squared return noisy series, residual employed proxy a...
The aim of study is to forecast global tourist visits and compare the forecasting methods determine best method using random forest, single exponential smoothing double smoothing, respectively. These are applied in visit data West Nusa Tenggara Province. Random familiar frequently utilized forecasting. In addition, three have great accuracy for time series data, such as visits. used this from 2...
this study purported to compare and contrast the use of self-mention and evidentials as two mtadiscourse features in opinion columns of persian and english newspapers. the theoretical basis of this study is the idea that metadiscourse features vary across cultural boundaries. for this purpose, 150 persian and 150 english opinion columns were collected based on three factors of topic, audience a...
Three general classes of state space models are presented, based upon the single source of error formulation. The first class is the standard linear state space model with homoscedastic errors, the second retains the linear structure but incorporates a dynamic form of heteroscedasticity, and the third allows for non-linear structure in the observation equation as well as heteroscedasticity. The...
abstract the present study deals with a comparison between reactive and pre-emptive focus-on-form in terms of application and efficiency. it was conducted in an intermediate english class in shahroud. 15 male learners participated in this research and their age ranged from 18 to 25. a course book, new interchange 3, and a complementary book were used. every session the learners gave lectures o...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
