Using Bayesian Aldrich‐McKelvey Scaling to Study Citizens' Ideological Preferences and Perceptions

Aldrich‐McKelvey scaling is a powerful method that corrects for differential‐item functioning (DIF) in estimating the positions of political stimuli (e.g., parties and candidates) and survey respondents along a latent policy dimension from issue scale data. DIF arises when respondents interpret issue scales (e.g., the standard liberal‐conservative scale) differently and distort their placements of the stimuli and themselves. We develop a Bayesian implementation of the classical maximum likelihood Aldrich‐McKelvey scaling method that overcomes some important shortcomings in the classical procedure. We then apply this method to study citizens' ideological preferences and perceptions using data from the 2004–2012 American National Election Studies and the 2010 Cooperative Congressional Election Study. Our findings indicate that DIF biases self‐placements on the liberal‐conservative scale in a way that understates the extent of polarization in the contemporary American electorate and that citizens have remarkably accurate perceptions of the ideological positions of senators and Senate candidates.     

Aspects of social differentiation in rural England,c. 1580–1660

The article attempts to identify and account for changes in local social relations which accompanied economic and social‐structural change in early‐modern England. An overview of recent findings is provided to highlight both the enduring characteristics of rural society in the period and the elements of change. Next it is argued that the aspects of change can be interpreted as a process of incorporation with economic, administrative and cultural dimensions which had the ultimate effect of promoting integration nationally, but differentiation locally. Particular illustration of this general argument is given in an examination of change in the Essex village of Terling.     

Federal Systems in the Global Economy: Research Issues

The emerging global economy has altered makeup of federal systemsand set the stage for new international institutions. This articleidentifies key research issues that bear upon the connectionbetween federalism and globalism. Five specific research questions are considered. The first concernsthe impact of global economic change on the sovereignty of nationaland subnalional governments. Second, the effect of the globaleconomy on intergovernmental relations is considered. Next,the question of placement of economic policy responsibilitiesin a federal system is posed. Finally, the article asks whetherfederalism eases adaptation to the global economy and protectsdemocratic values.
