In addition, the selection process of two Chinese Joint Ventures is reviewed. The paper emphasizes the importance of conducting structured job relevant, behaviour or situation based interviews, with pre determined guideline answers and examples provided. The research showing the increased predictive validity of using this type of interview format is presented. The types of outcomes sought by Canadian employers and the attributes employees or agents should possess are provided. It is argued that these should serve as the basis for creating the interview format. The use of testing and reference checks is also discussed.展开更多

The first goal, by means of variable selection, is of particular importance when the true underlying model has a sparse representation. Discovering relevant predictors can enhance the performance of the prediction for the fitted model. Usually an estimate is considered desirable if it is consistent in terms of both coefficient estimate and variable selection. Hence, before we try to estimate the regression coefficients β , it is preferable that we have a set of useful predictors m hand. The emphasis of our task in this paper is to propose a method, in the aim of identifying relevant predictors to ensure screening consistency in variable selection.
