Multivariate MRP

open access: yes
Measuring public opinion at subnational geographies is critical to many theories in political science. Multilevel regression and post-stratification (MRP) is a popular tool for doing so, although existing work is limited to measuring opinion on a single survey question. We provide a framework for estimating the joint distribution of opinion on multiple

Viperin mRNA is a novel target for the human RNase MRP/RNase P endoribonuclease

open access: yesCellular and Molecular Life Sciences, 2010
RNase MRP is a conserved endoribonuclease, in humans consisting of a 267-nucleotide RNA associated with 7–10 proteins. Mutations in its RNA component lead to several autosomal recessive skeletal dysplasias, including cartilage-hair hypoplasia (CHH ...

Single Site Mutations in the Hetero-oligomeric Mrp Antiporter from Alkaliphilic Bacillus pseudofirmus OF4 That Affect Na+/H+ Antiport Activity, Sodium Exclusion, Individual Mrp Protein Levels, or Mrp Complex Formation*

open access: yesJournal of Biological Chemistry, 2010
Mrp systems are widely distributed and structurally complex cation/proton antiporters. Antiport activity requires hetero-oligomeric complexes of all six or seven hydrophobic Mrp proteins (MrpA–MrpG). Here, a panel of site-directed mutants in conserved or

IRT‐based response style models and related methodology: Review and commentary

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract We provide a review and commentary on recent methodological research related to item response theory (IRT) modelling of response styles in psychological measurement. Our review describes the different categories of IRT models that have been proposed, their associated assumptions and extensions, and the varying purposes they can serve.

Generic Continuous Spectrum for Ergodic Schr"odinger Operators

open access: yes, 2007
We consider discrete Schr"odinger operators on the line with potentials generated by a minimal homeomorphism on a compact metric space and a continuous sampling function. We introduce the concepts of topological and metric repetition property.

Aggregate productivity effect of labour and capital market distortions in Canada

open access: yesCanadian Journal of Economics/Revue canadienne d'économique, EarlyView.
Abstract How efficiently are workers, investment capital, and production distributed across firms in Canada? And how have they varied over time, across regions, and between sectors? To answer these questions, we present novel measures of the degree of resource misallocation over time and space using uniquely detailed firm‐level data (T2‐LEAP) between ...
