This article describes 3 general theoretical orientations regarding the psychosocial determinants of children’s television viewing habits. A series of specific hypotheses are then tested via multiple regression analyses of data from 23 large-scale representative sample surveys. Vardenafil Generic Uk Consistent with the need satisfaction perspective, television-viewing frequency was related to social integration with peers, intelligence, book reading, and the hostility of parental punishment methods. Among preadolescents, television viewing was positively related to time spent with parents in families where parent-child coviewing is common, but among preadolescents who rarely coview and among all adolescents, parent-child contact was unrelated to viewing time. Frequency of interpersonal conflict with parents… http://www.vardenafilgenericuk.nu was also unrelated to television exposure. Consistent with the parental influence perspective, amount of viewing was associated with parental values for self-direction and with the imposition of rules restricting viewing. And consistent with the resource availability perspective, television viewing was related to the amount of time spent working at after-school jobs but, surprisingly, Vardenafilgenericuk not to family income. The strengths of some of these relations varied according to age. Implications of these findings regarding the psychosocial determinants of media exposure and regarding child development are discussed.
This article deals with the relation between a theory of law and a theory of legal reasoning. Starting from a close reading of Chapter VII of H. L. A. Hart’s The Concept of Law, it claims that a theory of law like Hart’s requires a particular theory of legal reasoning, or at least a theory of legal reasoning with some particular characteristics. Vardenafilgenericuk It then goes on to say that any theory of legal reasoning that satisfies those requirements is highly implausible, http://www.vardenafilgenericuk.nu and tries to show that this is the reason why not only Hart, but also writers like Neil MacCormick and Joseph Raz have failed to offer a theory of legal reasoning that is compatible with legal positivism as a theory of law. They have faced a choice between an explanation of legal reasoning that is incompatible with the core of legal… https://en.wikipedia.org/wiki/Vardenafil positivism or else strangely sceptical, insofar as it severs the link between general rules and particular decisions that purport to apply them.
The interaction among the reacting species in the NO–CO reaction on a metal catalytic surface that proceeds according to the Langmuir–Hinshelwood thermal mechanism is studied by means Vardenafilgenericuk of Monte Carlo simulations. The study of this system is essential for the understanding of the influence of impurities on the catalytic oxidation of NO by CO. It is found that this complex system exhibits irreversible phase transitions between active states with sustained reaction and poisoned states without reaction. http://www.vardenafilgenericuk.nu The same system has also been investigated by non-thermal (Eley-Rideal) mechanism. Both the phase diagrams of the surface coverage and the steady state production of CO 2 and N 2 are evaluated as a function of the partial pressures of the reactants in the gas phase. From this study, it is… observed that with the increase of impurities, Vardenafil Uk the production rate reduces and the reaction stops at a certain point. Moreover, the first order transition in the phase diagram converts into second order phase transition that is in accordance with the experimental findings. Therefore, the first order phase transition, which is a characteristic of such catalytic reactions, is eliminated.
