Journal of Forestry, 1939
Abstract Accelerated by a growing public consciousness for more conservative methods in the harvesting of timber crops, the selective form of cutting has received favorable and valuable publicity. Of necessity public definition of the method has been given in terms of values which might be achievedrather than in terms of problems ...

A log-linear modeling framework for selective mixing
Mathematical Biosciences, 1991Nonrandom mixing can significantly alter the diffusion path of an infectious disease such as AIDS that requires intimate contact. Recent attempts to model this effect have sought a general framework capable of representing both simple and arbitrarily complicated mixing structures, and of solving the balancing problem in a nonequilibrium multigroup ...

Spruce-Fir Selective Logging Costs
Journal of Forestry, 1942Abstract The economic feasibility of partial cutting methods is not commonly accepted. In spruce-fir stands of pulpwood size in the Northeast, logging with horses on partial cuttings removing 10 to 60 percent of the stand shows that costs do not exceed clear-cutting costs, with strong indications that selective cutting will become ...

A log-spiral antenna with selectable polarization
IEEE Transactions on Antennas and Propagation, 1971It is possible to obtain polarization diversity from one multiple arm logarithmic-spiral antenna. The log-spiral antenna with more than 2 arms can be excited by a single hybrid matrix connected to the antenna terminals at the origin of the antenna geometry, and operated such that currents flow on the arms with phase progression away from the origin and

A Note on the Selection of Log-Linear Models
Biometrics, 1980A recent paper in the Consultant's Forum by Benedetti and Brown (1978) discusses possible strategies for the choice of an appropriate log-linear model for a comples contingency table. The methods considered do not invariably choose the same model, but the authors favour the tests of marginal and partial association due to Brown (1976).

Portfolio Selection in a Log-Stable Market
The Journal of Financial and Quantitative Analysis, 1975The Stable (or Pareto-Levy) distribution has been of considerable interest in describing the behavior of security prices ever since the important work by Mandelbrot [6], [7] and Fama [1]. The aforementioned contributions focused on the empirical hypothesis that security price data are better fitted by theoretical distributions with infinite variance ...
