The paper considers empirical Bayes (EB) and hierarchical Bayes (HB) predictors of the finite population mean under a linear regression model with measurement errors We discuss how to calculate the mean squared prediction errors of the EB predictors using jackknife methods and the posterior standard deviations of the HB predictors based on the Markov Chain Monte Carlo methods. A simulation study is provided to illustrate the results of the preceding sections and compare the performances of the proposed procedures.

Purpose: The purpose of this study was to examine the levels of burnout experienced by Korean hospital nurses (N=198), and to identify predictors of their nursing outcomes such as job performance, work satisfaction, and productivity. Method: Hierarchical multiple regression was used to identify predictors of each nursing outcomes. Included predictors were nurses' general characteristics, work- related characteristics (role stress and perceived control), and burnout. Results: Korean nurses experienced higher levels of burnout compared to the cutoffs suggested by Maslach and Jackson (1986) and to those in the USA. For each nursing outcome, predictor variables explained 39% of the variance in role performance, 30% of the variance in work satisfaction, and 38% of variance in productivity. Higher personal accomplishment, lower role ambiguity, being staff nurses, and lower emotional exhaustion were related to higher job performance, and higher productivity. Lower role conflict and role ambiguity were also related to higher work satisfaction. Conclusion: Based on the findings of this study, managemental interventions for nurses to reduce their burnout experience are needed. Further study in this area is warranted.

Method: The sample of this study consisted of 267 nurses from 3 general hospitals located in Seoul, Korea. Data were collected with self-administrated questionnaires and analyzed hierarchical multiple regression. Result: The distributive and procedural justices had effects on nurses' job satisfaction and organizational commitment, but no effects on health. The procedural justice had more effects on nurses' job satisfaction and organizational commitment than distributive justice. There was no moderating effect of distributive and procedural justices on nurses' job satisfaction, organizational commitment and health. Conclusions: It is important for hospitals to be established fair reward systems which should focus on both outcomes and processes in order to evaluate nurses' rewards. It is suggested that new moderators like personality or organizational structure should be considered for future research.
