An equivalence relation in the symmetric group , where is a positive integer has been considered. An algorithm for calculation of the number of the equivalence classes by this relation for arbitrary integer has been described. n S 2 n3 n

We give a necessary and sufficient condition for the existence of a representation for a relation by a positive measure for the general case in which the relation is defined on any set of subsets of Q.

serum ferritin (sf) levels in 734 seven-year-old children was measured by a radioimmuno assay method, and its possible relation-ship with hemoglobin, hematocrit and mchc was investigated. the results showed there was positive correlation between sf with hemo-globin, hematocrit and mchc values.

A relation expressing the covariant transformation properties of a relativistic position operator is derived. This relation differs from the one existing in the literature expressing manifest covariance by some factor ordering. The relation is derived in order for the localization of a particle to represent a space-time event. It is shown that there exists a conflict between this relation and t...

Executive compensation is designed to create incentives for CEOs to act in the best interest of shareholders. Short-term (bonus) and equity-based incentives induce risk taking behaviors of the CEO that could further change a firm’s risk exposure. This article examines the linkage between compensation components and the impacts on a firm’s credit risk using data from the U.S. and Germany. In the...
