Entanglement of orbital angular momentum for the signal and idler beams in parametric down-conversion

We calculate the anticipated correlation between measurements of the orbital angular momentum of the signal and idler beams for parametric down-conversion. These calculations apply to the experiments where the orbital angular momentum state is measured by the use of computer-generated holograms. Displacement of these holograms with respect to the beam axis allows the measurement of superpositions of Laguerre—Gaussian modes. The correlations between such superposition modes of the signal and idler beams show their entanglement and could be used for Bell-type tests of nonlocality.     

EXTROVERSION AND STIMULUS-SEEKING MOTIVATION.

FROM EYSENCK'S PERSONALITY THEORY AND RECENT NOTIONS OF STIMULUS-SEEKING BEHAVIOR, IT WAS PREDICTED THAT EXTRAVERSION WOULD CORRELATE WITH STIMULUS SEEKING AS MEASURED BY THE SENSATION SEEKING SCALE OF ZUCKERMAN, KOLIN, PRICE, AND ZOOB. THE CORRELATION FOUND WAS .47, P     

A REQUISITELY HOLISTIC VIEW OF HUMAN RESOURCES MANAGEMENT IN INNOVATIVE ENTERPRISES

ABSTRACT

This paper first briefly presents the environment and challenges that companies will encounter in the current decade, enhancing innovative society and business style. On this basis, the authors investigate the challenges that will impact the implementation of human resources management in companies as a cybernetic system. Because there exists a two-way link between the companies and the environment, this contribution also illustrates the link in the other direction and shows how a company can gain competitive advantage by effective human resources management. The point is that companies are moving from being knowledge-based to being creativity-based to be sustainable and innovative businesses. They need requisite holism in their conception and cybernetics in their action to succeed in this complex move. We suggest a cybernetic model aimed at meeting this need.
