Sources of relative clause processing difficulty: Evidence from Russian

This study investigates the sources of processing difficulty in complex sentences involving relative clauses (RCs). Self-paced reading and eye tracking were used to test the comprehension of Russian subject- and object-extracted RCs (SRCs and ORCs) that had the same word-order configuration, but different noun phrase (NP) types (full NPs vs. pronouns) in the embedded clause. In both SRCs and ORCs, this NP intervened between the modified noun and the RC verb. A corpus analysis and acceptability rating experiment indicated different frequency/preference profiles for this word order depending on RC type and embedded NP type. In line with these profiles, processing difficulty was revealed early in the embedded clause for less frequent/dispreferred constructions. Later in the embedded clause, the processing of the RC verb was comparable for both SRCs and ORCs when the same number of NP arguments was available for integration. While there were no indications of an ORC penalty at or after this verb, late-stage comprehension difficulty was found for full-NP ORCs, but not for their pronominal counterparts, suggesting that similarity-based interference in combination with ORC structure influences the overall comprehension of these sentences. Taken together, these findings support a hybrid model under which independent sources of processing difficulty affect different stages of RC comprehension.

ConclusionsA MEL‐A2 with novel composition and surface activities was efficiently produced from a novel MEL producer. This is the first report on production of MEL‐A2 as the major product and from soybean oil. The biosurfactant has potential application as a wetting agent and oil‐in‐water emulsifier. Significance and Impact of the StudyDiscovery of novel structures and novel strains is valuable for further commercial development and application of MELs. Sporisorium sp. aff. sorghi SAM20 can be considered as a potential candidate for commercial production of biosurfactants.This article is protected by copyright. All rights reserved.

This article is protected by copyright. All rights reserved. The phosphodiesterase VieA regulates gene expression by modifying the intracellular cyclic diguanylate pool. This article reveals the differential regulation of VieA in Vibrio cholerae O1 biotypes. Expression of VieA is repressed by the nucleoid‐associated protein H‐NS and the LysR‐type regulator LeuO in classical biotype V. cholerae, and by H‐NS and the quorum sensing regulator HapR in the El Tor biotype.

We describe approaches for back‐calculating model parameter estimates and their standard errors from available summary statistics with various techniques, including approximate Bayesian computation. We propose to use a quadratic approximation to the log‐likelihood for each historical trial based on 2 independent terms for the log mean rate and the log of the dispersion parameter. A Bayesian hierarchical meta‐analysis model then provides the posterior predictive distribution for these parameters. Simulations show this approach with back‐calculated parameter estimates results in very similar inference as using parame...
