Psychometrics With R: A Review Of CRAN Packages For Item Response Theory
No full textIn this paper we review the current state of R packages for Item Response Theory (IRT).
We group the available packages based on their purpose and provide an overview of each
package's main functionality. Each of the packages we describe has a peer-reviewed publication
associated with it. We also provide a tutorial analysis of data from the 1990
Workplace Industrial Relation Survey to show how the breadth and
exibility of IRT
packages in R can be leveraged to conduct even challenging item analyses with versatility
and ease. These items relate to the type of consultations that are carried out in a firm
when major changes are implemented. We first use unidimensional IRT models just to
discover that they fit do not fit well. We then use nonparametric IRT to explore the
possible causes for the scaling problem. Based on the results from the exploration, we
finally use a two-dimensional model on a subset of the original items to achieve a good
fit with a sensible interpretation, namely that there are two types of consultations a firm
may engage in: consultations with workers/representatives from the firm and with official
union representatives. The different items relate mostly to one of these dimensions and
firms can be scaled well along these two dimensions.Series: Discussion Paper Series / Center for Empirical Research Method

Peter Mair
No full textDr. Peter Mair, Professor of Comparative Politics and Government at the EUI (Florence) has suddenly and unexpectedly passed away, 15 August 2011, at the age of 60. He leaves behind his wife and 3 children. The political science community in Europe and beyond grieves this loss of an outstanding academic, journal editor and teacher. Peter Mair, born 3 March 1951, was a native of Ireland, a graduate of University College Dublin and enjoyed a distinguished academic career and was the author of a large number of books, chapters and articles on comparative and European politics and on party democracy in particular. It is a sad loss to European political science. He graduated in 1974 and began his career as an assistant professor at the University of Limerick. He subsequently lectured at the universities of Strathclyde and Manchester before moving to the European University Institute of Florence in 1979. He moved to the University of Leiden in the Netherlands in 1987 and was appointed professor of comparative politics in 1992. In 2005 he returned to Florence and was appointed head of the department of political and social sciences in 2007. Prof Mair specialised in the study of party and party systems and has written a number of books on the subject. He was co-author of Representative Government in Modern Europe, the fifth edition of which was published this year. He was also co-author of Identity, Competition and Electoral Availability, which was awarded the prestigious Stein Rokkan prize. Peter Mair served the comparative political science community by editorships of the internationally reputed European Journal of Political Science and of West European Politics. Peter was a person of great charm, a congenial colleague and always encouraging students. We grieve over his loss and sympathize with his family he left behind too early and too soon.</jats:p
