This study explained the use of standard scores otherwise known as z scores for research in educational management. Since a score is a unit distance between two limits, the individual given a score in percentage might have actually scored between the lower limit and the upper limit of that score. A score therefore represent the mid-point between the lower limit and the upper limit of the score....

OBJECTIVE To develop a composite patient safety score that provides patients, health-care providers, and health-care purchasers with a standardized method to evaluate patient safety in general acute care hospitals in the United States. METHODS The Leapfrog Group sought guidance from a panel of national patient safety experts to develop the composite score. Candidate patient safety performance...

We consider a new discriminative learning approach to sequence labeling based on the statistical concept of the Z -score. Given a training set of pairs of hidden-observed sequences, the task is to determine some parameter values such that the hidden labels can be correctly reconstructed from observations. Maximizing the Z -score appears to be a very good criterion to solve this problem both the...

OBJECTIVE To explore the effects of maternal smoking during pregnancy on offspring growth using three approaches: (1) multiple adjustments for socioeconomic and parental factors, (2) maternal-paternal comparisons as a test of putative intrauterine effects and (3) comparisons between two birth cohort studies. METHODS Population-based birth cohort studies were carried out in Pelotas, Brazil, in...
