    Discontinuous and nondifferentiable functions and dimension increase induced by filtering chaotic data (1996)

    Notes: We show that one can use recently introduced statistics for continuity and differentiability to show the effect of filters of infinite extent in time on a chaotic time series. The statistics point to a discontinuous or nondifferentiable function between the unfiltered attractor and the filtered attractor as the origin of attractor dimension increase when the filtering is severe. The density of discontinuities as a function of resolution follows a scaling relation. We present direct visualization of this effect in the filtered Henon attractor where the origin of dimension increase becomes obvious.

    Fundamentals of synchronization in chaotic systems, concepts, and applications (1997)

    Notes: The field of chaotic synchronization has grown considerably since its advent in 1990. Several subdisciplines and "cottage industries" have emerged that have taken on bona fide lives of their own. Our purpose in this paper is to collect results from these various areas in a review article format with a tutorial emphasis. Fundamentals of chaotic synchronization are reviewed first with emphases on the geometry of synchronization and stability criteria. Several widely used coupling configurations are examined and, when available, experimental demonstrations of their success (generally with chaotic circuit systems) are described. Particular focus is given to the recent notion of synchronous substitution—a method to synchronize chaotic systems using a larger class of scalar chaotic coupling signals than previously thought possible. Connections between this technique and well-known control theory results are also outlined. Extensions of the technique are presented that allow so-called hyperchaotic systems (systems with more than one positive Lyapunov exponent) to be synchronized. Several proposals for "secure" communication schemes have been advanced; major ones are reviewed and their strengths and weaknesses are touched upon. Arrays of coupled chaotic systems have received a great deal of attention lately and have spawned a host of interesting and, in some cases, counterintuitive phenomena including bursting above synchronization thresholds, destabilizing transitions as coupling increases (short-wavelength bifurcations), and riddled basins. In addition, a general mathematical framework for analyzing the stability of arrays with arbitrary coupling configurations is outlined. Finally, the topic of generalized synchronization is discussed, along with data analysis techniques that can be used to decide whether two systems satisfy the mathematical requirements of generalized synchronization. © 1997 American Institute of Physics.

    Left–right party ideology and government policies: A meta–analysis (2001)

    Notes: Abstract. This paper summarizes how the partisan influence literature assesses the relationship between the left–right party composition of government and policy outputs through a meta–analysis of 693 parameter estimates of the party–policy relationship published in 43 empirical studies. Based on a simplified ‘combined tests’ meta–analytic technique, we show that the average correlation between the party composition of government and policy outputs is not significantly different from zero. A mutivariate logistic regression analysis examines how support for partisan theory is affected by a subset of mediating factors that can be applied to all the estimates under review. The analysis demonstrates that there are clearly identifiable conditions under which the probability of support for partisan theory can be substantially increased. We conclude that further research is needed on institutional and socio–economic determinants of public policy.

    Aid and ideology (1988)

    Notes: Abstract. A conceptualization of international aid-giving behaviour, based on the notion of bounded rationality and involving the interaction of objective and subjective factors, is developed. From this conceptualization, four hypotheses are deduced to explain the variation of development aid expenditures as a percentage of GNP: the instrumental hypothesis, the humanitarian hypothesis, the ideological hypothesis, and the incremental hypothesis. These hypotheses are tested on data concerning aid allocations of 17 OECD donors for four points in time (1966, 1971, 1976, and 1981), through the use of a regression model. Results show that the model as a whole explains between 85% and 96% of the variance in the dependent variable. Tests of individual hypotheses show that the instrumental explanation is the best predictor of aid as a percentage of GNP if a lagged value of the dependent variable is used on the right-hand side of the equation. When the lagged value of the dependent variable is dropped from the equations, the best predictor is the ideological explanation. The contribution of the humanitarian explanation to the explained variance is negligible.

    Identification of a Microsporidian Polar Tube Protein Reactive Monoclonal Antibody (1996)

    Notes: . The microsporidia are characterized by spores containing a single polar tube that coils around the sporoplasm. When triggered by appropriate stimuli, the polar tube rapidly discharges out of the spore forming a hollow tube. The sporoplasm passes out of the spore through this tube serving as a unique vehicle of infection. Due to the unusual functional and solubility properties of the polar tube, the proteins comprising it are likely to be members of a protein family with a highly conserved amino acid composition among the various microsporidia. Polar tube proteins were separated from the majority of other proteins in glass bead disrupted spores of Glugea americanus using sequential 1% sodium dodecyl sulfate (SDS) and 9M urea extractions. The resultant spore pellet demonstrated broken, empty spore coats and numerous polar tubes in straight and twisted formations by negative stain transmission electron microscopy. After subsequent incubation of the pellet with 2% dithiothreitol (DTT), empty spore coats were still observed but the polar tubes were no longer present in the pellet. The DTT supernatant demonstrated four major protein bands by SDS-PAGE: 23, 27, 34 and 43 kDa. Monoclonal antibodies were produced to these proteins using Hunter's Titermax adjuvant. Mab 3C8.23.1 which cross-reacted with a 43-kDa antigen by immunoblot analyis, demonstrated strong reactivity with the polar tube of G. americanus spores by immunogold electron microscopy. This antibody will be useful in further characterization of polar tube proteins and may lead to novel diagnostic and therapeutic reagents.
