Mapping the Irish Policy Space:Voter and Party Spaces in Preferential
In this note we map the Irish policy space, locating both voters and parties on the most salient policy dimensions in Ireland. Estimates of the voter locations are based on the Irish National Election Survey (INES), conducted in 2002. Estimates of the party positions are based on an expert survey of party positions conducted by the authors in late 2002. We show that respondent self-placements on a priori policy scales are highly biased and difficult to interpret, and we rely instead on building scale positions for respondents from their answers to relevant attitude questions in the INES. The results provide a methodological template for locating voters and parties in a common space â a significant problem for any analyst who wants to create an empirical elaboration of a spatial model of party competition.
Temporal behavior of the SO 1.707 micron ro-vibronic emission band in Io's atmosphere
We report observations of the ro-vibronic transition of SO at 1.707 microns
on Io. These data were taken while Io was eclipsed by Jupiter, on four nights
between July 2000 and March 2003. We analyze these results in conjunction with
a previously published night to investigate the temporal behavior of these
emissions. The observations were all conducted using the near-infrared
spectrometer NIRSPEC on the W.M. Keck II telescope. The integrated emitted
intensity for this band varies from 0.8 x 10^27 to 2.4 x 10^27 photons/sec,
with a possible link to variations in Loki's infrared brightness. The
band-shapes imply rotational temperatures of 550-1000K for the emitting gas,
lending further evidence to a volcanic origin for sulfur monoxide. An attempt
to detect the ro-vibronic transition of SO at 0.97 microns was unsuccessful;
simultaneous detection with the 1.707 micron band would permit determination of
the SO column abundance.Comment: 10 pages 4 figures. Accepted by Icarus 02/27/200
Component-resolved Near-infrared Spectra of the (22) Kalliope System
We observed (22) Kalliope and its companion Linus with the integral-field
spectrograph OSIRIS, which is coupled to the adaptive optics system at the W.M.
Keck II telescope on March 25 2008. We present, for the first time,
component-resolved spectra acquired simultaneously in each of the Zbb (1-1.18
um), Jbb (1.18-1.42 um), Hbb (1.47-1.80 um), and Kbb (1.97-2.38 um) bands. The
spectra of the two bodies are remarkably similar and imply that both bodies
were formed at the same time from the same material; such as via incomplete
re-accretion after a major impact on the precursor body.Comment: 20 pages, 5 figures, 1 table. Accepted for publication in Icaru
