Using Busch's single-item power scales as a point of reference, the author examines the quality of Holzbach's multi-item attributed power index. The Holzbach scale is found to represent an improvement in the measurement of power base utilization in sales manager–sales representative relationships.

In a study of a limited epidemic of S. typhimurium infections in humans, the plasmid content (pattern) of bacteria was used as an epidemiologic tool outside the hospital environment. Comparisons were made with lysotyping, resistance pattern determination (14 antibiotics) and biotyping. Plasmid pattern determination was as useful and accurate as lysotyping;resistance pattern determination was of more limited interest. Biotyping was of no use.
Italian agriculture is highly energy efficient due to low machinery and fuel use. Pesticides will represent 1/3 of the total energy used in crop production by 1988, following a 66% increase in pesticide use over 1978....

Italian agriculture is highly energy efficient due to low machinery and fuel use. Pesticides will represent 1/3 of the total energy used in crop production by 1988, following a 66% increase in pesticide use over 1978. Many pesticides used in Italy were cancelled or restricted for use in the USA.

We consider a class of iterative algorithms for solving systems of linear equations where the coefficient matrix is nonsymmetric with positive-definite symmetric part. The algorithms are modelled after the conjugate gradient method, and are well suited for large sparse systems. They do not make use of any associated symmetric problems. Convergence results and error bounds are presented.
