Party identification and party closeness in comparative perspective

The present analysis uses data from 1974 and 1981 U. S. cross sections, which incorporate a panel, to compare the standard NES measure of party identification (ID) with a measure of partisanship derived from a party closeness question widely employed in cross-national research. Important features of the two scales are examined by transforming the closeness measure into a scale of very close, fairly close, not very close, and no preference corresponding to the seven-point ID scale. The scales are highly correlated and are similar in their reliability. More than 75% of the “independents” in the ID scale choose a party in the closeness version, and over half of these select the “fairly close” category. Respondents do not volunteer that they are independents when that alternative is not stated in the question.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45482/1/11109_2004_Article_BF00990552.pd

It's About Time: Modelling Political and Social Dynamics

Extending the basic regression model to the analysis of processes, which entail modelling time. The example demonstrates using Box?Jenkins ARIMA intervention and transfer function models, and error correction models, and introduces and interprets statistical tests such as the Q?test and the Dickey?Fuller t?ratio

Straightforward field calculations for uniaxial hardmagnetic prisms: stray field distributions and dipolar coupling in regular arrays

Elements of hard- or moderately hardmagnetic materials may exhibit remanent states with a stable uniform magnetization distribution due to the high magnetocrystalline anisotropy energy. In this work, we present analytical calculations of magnetic field distributions arising from appropriate prismatic magnets and apply the results to the special case of hardmagnetic cuboids. The influence of the aspect ratio on the stray field distribution and its range is analysed. Based on these calculations a simple quasi-phase diagram for the emergence of dipolar coupling between individual elements with perpendicular easy axis in regular arrays is derived
