An econometric study of automated stabilization policies in Japan

We report two experiments investigating the effect of phonological priming on the recognition of two types of Chinese characters: compound targets which contain separate radical components; and integrated targets which do not contain separate radicals. We used a masked priming paradigm with varying prime-target exposure durations. In Experiment I, phonological priming effects on compound target recognition were found following a 50 msec SOA. However, there was no evidence of phonological priming on integrated target recognition at this SOA. In Experiment 2 we investigated the time course of phonological priming effects at three prime-target SOAs (30, 50 and 80 msec) in a between-subjects design. Semantic priming effects were also investigated. Phonological priming effects on compound target recognition were found following the 50 msec and the 80 msec SOAs. However, there was no evidence of phonological priming on integrated target recognition at any SOA. Semantic priming effects on both compound and integrated target recognition were found in the 50 msec and the 80 msec SOA conditions suggesting that phonological and semantic activation are coincidental during compound character recognition. We conclude that character type constrains the activation of phonology during Chinese character recognition

Metabolism and regulation of canonical histone mRNAs: life without a poly(A) tail

The canonical histone proteins are encoded by replication-dependent genes and must rapidly reach high levels of expression during S phase. In metazoans the genes that encode these proteins produce mRNAs that, instead of being polyadenylated, contain a unique 3' end structure. By contrast, the synthesis of the variant, replication-independent histones, which are encoded by polyadenylated mRNAs, persists outside of S phase. Accurate positioning of both histone types in chromatin is essential for proper transcriptional regulation, the demarcation of heterochromatic boundaries and the epigenetic inheritance of gene expression patterns. Recent results suggest that the coordinated synthesis of replication-dependent and variant histone mRNAs is achieved by signals that affect formation of the 3' end of the replication-dependent histone mRNAs
