Although numerous studies have examined the relationship between family and religion on delinquency, there have not been studies of the relationship between parents, friends, and religion on substance use among adults. The analysis for this study was based on two waves of data (Wave 1, 1986 and Wave 2, 1989) of the Americans’ Changing Lives Survey. The results revealed that social relationships, social integration and attendance at religious services influence the number of drinks and cigarettes smoked per day among adults. Parental influence varies by gender. The implications for social control, social networks and gender perspectives are discussed.
In this paper the problem of practical stabilization for a significant class of MIMO uncertain pseudo-linear and pseudo-quadratic systems, with additional bounded nonlinearities and/or bounded disturbances, is considered. By using the concept of majorant system, via Lyapunov approach, new fundamental theorems, from which derive explicit formulas to design state feedback control laws, with a possible imperfect compensation of nonlinearities and disturbances, are stated. These results guarantee a specified convergence velocity of the linearized system of the majorant system and a desired steady-state output for generic uncertainties and/or generic bounded nonlinearities and/or bounded disturbances.
