Violent tactics in family conflict relative to familial and economic factors.

A study was conducted to examine the social, economic, and family process factors which may be associated with families' use of violent tactics in conflict within an homogeneous population in the Appalachian region of southwestern Virginia. The primary hypothesis stated that economic conditions as set by the employment status of parents would be a significant factor in predicting use of violence in the resolution of family conflict. The study employed a questionnaire modeled after that used in a national study of family violence conducted by Straus, Gelles, and Steinmetz in 1980 with additional items developed to assess regional family processes and economic conditions. 114 boys and 161 girls ranging in age from 15 to 17 yr. participated. Statistical analysis confirmed the major hypothesis: in families where the father was unemployed, there was greater than expected frequency of reported violent interactions. Additional findings included associations between previous generation's abuse and use of violent interactions as well as sex of subject and use of violent interactions.

Optimal solutions to a linear inverse problem in geophysics.

This paper is concerned with the solution of the linear system obtained in the Backus-Gilbert formulation of the inverse problem for gross earth data. The theory of well-posed stochastic extensions to illposed linear problems, proposed by Franklin, is developed for this application. For given estimates of the statistical variance of the noise in the data, an optimal solution is obtained under the constraint that it be the output of a prescribed linear filter. Proper specification of this filter permits the introduction of information not contained in the data about the smoothness of an acceptable solution. As an example of the application of this theory, a preliminary model is presented for the density and shear velocity as a function of radius in the earth's interior.
