Studies on leadership, by both laymen and academicians, abound. It is an oft- studied concept that has experienced a distinct evolutionary cycle typical of much of social science research. This paradigm is utilized to describe a variety of investi gations that suggest that self-esteem is a significant variable in individual produc tive functioning and leadership effectiveness. This literature is reviewed, focusing not on characteristics of a leader, but on superior-subordinate interactions. A con ceptual framework is presented that describes the importance of self-esteem, how it is affected in organization contexts, and what implications are apparent, given this evidence, for researchers, managers, and consultants.

The theory of participative management has held the spotlight of debate in management literature. This article examines the purposes of participative management and, using different systems and models, discusses its advantages and disadvantages.

Analytical expressions describing the characteristic performance curves of the Roots blower have been developed in the following work. These are especially useful in simulating Roots blower performance on the digital computer, as well as showing quantitatively the interplay between the parameters affecting performance.

For maximum operating efficiency of Roots type blowers, the leakage of compressed air through clearance must be reduced to a minimum. At the same time it is desirable to keep the design as compact as possible. The following analysis endeavours to show, for involute rotors, the effect of the geometrical design variables, pressure angle, rotor tip radius, and base circle radius, on leakage and compactness. Firstly limits of permissible values of the geometrical design variables, to allow correct mating between rotors, are established. Within these limits, relative blower compactness and carry-over of compressed air back to the inlet tract is obtained for the ideal blower with no clearance between relative rotating parts. The analysis and results are expressed in dimensionless form independent of blower size, and results are compared with cycloid rotors. Leakage through blower clearances, in terms of the geometrical design variables, is then determined for a range of pressure ratios, and the dependence on blower size is examined. It is concluded that optimum design values cannot be obtained. A compromise solution between minimum total leakage and maximum compactness is necessary, depending on the operating requirements for a particular Roots blower.
