An attempt is made here to construct and present relative efficiency indices for the services rendered by health districts and specific hospitals in Botswana, using Stochastic Frontier Regression analysis and Data Envelopment Analysis. The analysis indicated that three districts - Kweneng East,...

This paper describes a modification for the practical relevance of unit root tests for time series generated by linear stochastic difference equations with an explosive root.

The impetus for change in African legal reform is coming primarily from African women themselves, as they respond to their personal and practical experiences with the law. Top-down imposition of norms has not worked; if legal reform is to lead to sustainable equity for women, the voices of these...

In this paper an attempt has been made to introduce the concept of structural efficiency in incomplete block designs using the concept of majorization, an established concept in inequalities. Structural efficiency preserves the homogeniety or even distribution of treatments over the blocks.

L-superadditive functions find many applications in rearrangement inequalities, operations research and reliability. In this paper, we prove a theorem of integral transforms for L-superadditive functions that preserve Schur property.
