Estimation in generalized bivariate Birnbaum–Saunders models

In this paper, we propose two moment-type estimation methods for the parameters of the generalized bivariate Birnbaum–Saunders distribution by taking advantage of some properties of the distribution. The proposed moment-type estimators are easy to compute and always exist uniquely. We derive the asymptotic distributions of these estimators and carry out a simulation study to evaluate the performance of all these estimators. The probability coverages of confidence intervals are also discussed. Finally, two examples are used to illustrate the proposed methods.     

Do EHR investments lead to lower staffing levels?

A study used FTE employees per adjusted occupied bed (FTE/AOB) as a measure to ascertain the effect of EHR investments on labor productivity. The study focused on three primary questions: Do FTE/AOB decline as the number of EHR applications used in a hospital increases? Is impact on FTE/AOB greater with some EHR applications than with others? Do FTE/AOB decline overtime, as the hospital continues to use the EHR application?     

Values and Beliefs Related to Ethical Decisions

Although there is reason to suspect thatpeople's values and beliefs influenceintegrity-related decisions, few studies haveexamined the values and beliefs related tomanagerial integrity. In the present study,197 students were asked to complete measures ofvalues and beliefs as manifest in theirpreferred courses of action when confrontedwith ambiguous situations. Subsequently, theywere asked to work on a managerial ``in-basket'task where the decisions made might result inharm to others or harm to the organization. Itwas found that values and beliefs were relatedto both types of decisions producing multiplecorrelations in the 0.40s. People whose valuesstressed growth and contributions to others, asopposed to personal gain, and believed actionswere under their control, as opposed toexternal control, exhibited greater integrity. The implications of these findings forunderstanding leader integrity are discussed.
