    Notes: The low frequency (500–80 cm−1) Raman spectra of gaseous methylcyclobutane, c-C4H7CH3, and methyl-d3-cyclobutane have been recorded. A series of Q branches beginning at 161 cm−1 for the light molecule and 154 cm−1 for the d3 compound with successive transitions falling to lower frequencies have been assigned to the ring puckering vibrations of both the low energy equatorial and high energy axial conformers. These data have been fitted to an asymmetric potential function of the form: V(cm−1)=(4.78±0.10)×105X4−(3.08±0.04)×104X2 +(2.18±0.1)×104X3 with an assumed reduced mass of 160 amu for the light compound. Utilizing this potential the difference between the puckering angles for the two conformers was calculated to be 4.3° with the equatorial conformer having the larger value of 20.7°. A similar potential was obtained for the d3 molecule. The energy difference between the equatorial and axial forms was found to be 247±20 cm−1 (706 cal/mol) and a barrier of 641±20 cm−1 (1.83 kcal/mol) was found for the interconversion. Experimental values for the ΔH of both the liquid (354±179 cm−1) and gas (295±75 cm−1) from relative intensities of different Raman band pairs over 85 and 37 °C temperature ranges, respectively, were found to be consistent with the value obtained from the potential function. These results are compared to the corresponding quantities for similar molecules.

    Superspace formulation of general massive gauge theories and geometric interpretation of mass-dependent Becchi–Rouet–Stora–Tyutin symmetries (2000)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: A superspace formulation is proposed for the osp(1,2)-covariant Lagrangian quantization of general massive gauge theories. The superalgebra osp(1,2) is considered as subalgebra of the superalgebra sl(1,2)∼osp(2,2) which may be considered as the algebra of generators of the conformal group in a superspace with two anticommuting coordinates. The mass-dependent (anti)Becchi–Rouet–Stora–Tyutin symmetries of proper solutions of the quantum master equations in the osp(1,2)-covariant formalism are realized in that superspace as invariance under translations combined with mass-dependent special conformal transformations. The Sp(2) symmetry—in particular the ghost number conservation—and the new ghost number conservation are realized in the superspace as invariance under symplectic rotations and dilatations, respectively. The new ghost number conservation is generally broken by the choice of a gauge. The transformations of the gauge fields and the full set of necessarily required (anti)ghost and auxiliary fields under the superalgebra sl(1,2) are determined both for irreducible and first-stage reducible theories with closed gauge algebra. © 2000 American Institute of Physics.

    The osp(1,2)-covariant Lagrangian quantization of reducible massive gauge theories (1999)
    College Park, Md. : American Institute of Physics (AIP)
    Journal of Mathematical Physics 40 (1999), S. 6189-6208 
    Details
    ISSN: 1089-7658
    Source: AIP Digital Archive
    Topics: Mathematics , Physics
    Notes: The osp(1,2)-covariant Lagrangian quantization of irreducible gauge theories is generalized to L-stage reducible theories. The dependence of the generating functional of Green's functions on the choice of gauge in the massive case is discussed and Ward identities related to osp(1,2) symmetry are given. Massive first-stage theories with closed gauge algebra are studied in detail. The generalization of the Chapline–Manton model and topological Yang–Mills theory to the case of massive fields are considered as examples. © 1999 American Institute of Physics.

    Notes: Reintroduces alienation theory and research. Considers alienation in a cybernetic sense as a generic term for different types of information processing problems in individuals. Considers these, more often than not, to be ultimately caused by developments in their social environment and reflecting back on that environment. Discusses the emergence of virtual communities, giving as an example the Thematic Group on Sociocybernetics and Social Systems. Describes its function and composition in a virtual community context. Considers whether Norbert Wiener foresaw the emergence of virtual communities and examines the link with the society envisaged by Niklas Luhmann.

    Alienation, Participation and Increasing Societal Complexity (1994)
    Bingley : Emerald
    Kybernetes 23 (1994), S. 10-34

    Topics: Computer Science
    Notes: Provides definitions of the three concepts in the title and explores their interrelationships. Distinguishes six alienation dimensions - powerlessness; meaninglessness; normlessness; social isolation; cultural estrangement; self-estrangement - and combines them with three kinds of participation: spontaneous, negative, and compensatory. Describes increasing societal complexity from a general systems perspective. Explores the psycho- and sociogenesis of unalienated as well as alienated participation. Increasing societal complexity creates new forms of alienation and participation, but also resistances of groups that feel threatened or left out by an excessively fast rate of change, which in turn threatens macro-societal stability. Those left without the means to participate in the economic or political process tend to be the alienated "negative participants"; they are generally destructive and anti-outgroup as a result of personal experiences or economic deprivation.

    Details
    ISSN: 0368-492X
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Computer Science
    Notes: Summarizes some of the important concepts and developments in cybernetics and general systems theory, especially during the last two decades. Shows how they can indeed be a challenge to sociological thinking. Cybernetics is used here as an umbrella term for a great variety of related disciplines: general systems theory, information theory, system dynamics, dynamic systems theory, including catastrophe theory, chaos theory. Also considers the emerging "science of complexity", which includes neural networks, artificial intelligence and artificial life, and discusses the methodological drawbacks of second-order cybernetics.

    Pockets of irrationality in an increasingly rational world: An effort to simplify unmanageable environmental over-complexity? (2001)

    Notes: The transition is described from the "mediated society" (Lachs) to the "network society" (Castells), caused by the increasingly rapid complexification of modern society. On the level of psychic systems, i.e. the individual's consciousness, the modern network society promotes new (non-Marxist and non-psychiatric) forms of powerlessness and meaningless. On the level of social systems, i.e. the system of communications in the network society, the results of this are described. The network society is only partially developed: in some areas more than others, in the economic and political more than in the cultural sphere. As an example, the present-day situation in Yugoslavia is discussed, as well as the chances for the emergence of world-wide minimum norms, both ecological and anti-genocide.

    Notes: Based on an address given to the second international conference on sociocybernetics the author gives a personal view of globalization and sustainability. He discusses economy-driven, science-driven and tourism-driven globalization and gives a meaning to the term "sustainer", He gives examples of the "nastier aspects of globalization" and considers whether there is a realistic approach to globalization and sustainability problems. Deals from a sociocybernetic viewpoint with some of the challenges to be faced in the modern world.

    Details
    ISSN: 0368-492X
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Computer Science
    Notes: Focuses on the issue of increasing environmental and societal complexity, and its effects on the individual, especially visible in the increase of self-reference (the commonalities between man, animals and machines). Distinguishes three meanings of self-reference and discusses the interrelationships between self-reference, alienation, and growing societal complexity: states that, especially in the last few decades of this secular age, there has been increasing incidence of self-reference. Also discusses the relationship between self-reference, constructivism, and modern brain research. Asserts that the march of self-reference is likely to continue, but that it will change in character.
