Consistency between the radio and MIR faint source counts using the radio-MIR correlation

We show from the recent extrapolation of the radio-FIR correlation to the MIR that the 20 cm and 15 um differential source counts are likely to come from the same parent population.Comment: 2 pages, 2 figures, to appear in proceedings of 'Multi-wavelength AGN surveys', Cozumel, 200

A Generalization of Haldane state-counting procedure and π\pi-deformations of statistics

We consider the generalization of Haldane's state-counting procedure to describe all possible types of exclusion statistics which are linear in the deformation parameter $g$. The statistics are parametrized by elements of the symmetric group of the particles in question. For several specific cases we determine the form of the distribution functions which generalizes results obtained by Wu. Using them we analyze the low-temperature behavior and thermodynamic properties of these systems and compare our results with previous studies of the thermodynamics of a gas of $g$-ons. Various possible physical applications of these constructions are discussed.Comment: 17 pages, latex, 6 figures small corrections were made, reference and acknowledgments are adde

A Modified Magnitude System that Produces Well-Behaved Magnitudes, Colors, and Errors Even for Low Signal-to-Noise Ratio Measurements

We describe a modification of the usual definition of astronomical magnitudes, replacing the usual logarithm with an inverse hyperbolic sine function; we call these modified magnitudes `asinh magnitudes'. For objects detected at signal-to-noise ratios of greater than about five, our modified definition is essentially identical to the traditional one; for fainter objects (including those with a formally negative flux) our definition is well behaved, tending to a definite value with finite errors as the flux goes to zero. This new definition is especially useful when considering the colors of faint objects, as the difference of two `asinh' magnitudes measures the usual flux ratio for bright objects, while avoiding the problems caused by dividing two very uncertain values for faint objects. The Sloan Digital Sky Survey (SDSS) data products will use this scheme to express all magnitudes in their catalogs.Comment: 11 pages, including 3 postscript figures. Submitted to A

Authoritarian Aggression and Social Stratification: A Research Note

Ever since Seymour Martin Lipset's famous paper on authoritarianism and the left(1959), it has been widely assumed that blue collar workers are uniquely susceptible to the temptations of hate. Thisassumption was tested and (itseemed) confirmed by Melvin Kahn & Carmi Schooler (1983), among others. Yet in our recent research we have found contrary evidence - evidence suggesting, in fact, that comparatively high status professionals are significantly more authoritarian than other strata of the workforce. The starting point for this research was our hypothesis that the attitude questions in Erik Olin Wright's 15-nation study of Class Structure and Class Consciousness might correlate with Bob Altemeyer's time-tested "Rigbt Wing Authoritarianism" scale. Early tests of this thesis indicate that this seems to be true,at the .70 level;and subsequent analysis of Wright's first United States survey (1980) reveals a number of further correlations. Most notably, and contrary to the oft -reported findings ofKahn & Schooler, we found that white collar "experts" in Wright's study appear to have significantly more aggressive and authoritarian attitudes than lower status workers. (Their mean authoritarianism scores, respectively, are 2.85 and 2.31) These are preliminary findings, to be sure, and we are certainly not trying to vindicate the old chestnut that classical working-class status guarantees virtue - but if in fact this finding is borne out in further studies, it may prove important
