C. Wright Mils revisited: Society and Power

C. Wright Mills has been forgotten by sociological theories however there is no doubt about how much he contributed to the field of Epistemology. He successfully participated in the American Sociology of Knowledge and, at the same time, he  upheld the tradition of the Conflict Theory, including the sociological dimension into one of the most questioned political subjects of his period. Undoubtedly,  Wright Mills was morally committed to the value of reason and freedom. His central issue was to analyse the real possibilities for a particular individual within  a particular social order to become a free man capable of reasoning. He wondered how someone could be able to transcend his daily nature through reason and  experience and to act accordingly to his power. The power and political processes were constant in his works, since he claimed that any political process was a  struggle for power and prestige, for authoritative positions, both within each nation  and among the different states. On the other hand, he  bserved that the social  structure in the United States of America was not completely democratic, since the  course of action depended on the decision of a small group of wealthy, powerful individuals. These concentrating spaces of power amongst some economic, military  and political corporations were supported by their underlying ideology, a fact that became clearer when referring to international affairs. Nowadays, in a world of  structural antagonisms, wars and rebellions, the need for looking at the work  of intellectuals like Mills re-emerges. Mills showed us a way in which a complex entity as power can be understood, and, at the same time, the need to consider the  course of history, its mechanics and process.

Energy saving innovations, non-exhaustible sources of energy and long-run: what would happen if we run out of oil?

We formulate and solve a model of factor saving technological improvement considering three factors of production: labor, capital and energy. The productive activities have three main characteristics: first, in order to use capital goods firms need energy; second, there are two sources of energy: non-exhaustible and exhaustible; third, capital goods can be of different qualities and the quality of these goods can be changed along two dimensions -reducing the need of energy or changing the source of energy used in the production process. The economy goes through three stages of development after industrialization. In the first, firms make use of exhaustible energy and the e¢ ciency in the use of energy is constant. In the second stage, as the price of energy grows the e¢ ciency in its use is increased. In the third stage, the price of exhaustible sources is so high that firms have incentives to use non-exhaustible sources of energy. During this stage the price of energy is constant. In this set up, the end of the oil age has level effects on consumption and output but it does not cause the collapse of the economic system.

A chemical Hamiltonian approach study of the basis set superposition error changes on electron densities and one- and two-center energy components

A comparision of the local effects of the basis set superposition error (BSSE) on the electron densities and energy components of three representative H-bonded complexes was carried out. The electron densities were obtained with Hartee-Fock and density functional theory versions of the chemical Hamiltonian approach (CHA) methodology. It was shown that the effects of the BSSE were common for all complexes studied. The electron density difference maps and the chemical energy component analysis (CECA) analysis confirmed that the local effects of the BSSE were different when diffuse functions were present in the calculations
