Dynamic Model Averaging and CPI Inflation Forecasts: A Comparison between the Euro Area and the United States

The paper forecasts consumer price inflation in the euro area (EA) and in the USA between 1980:Q1 and 2012:Q4 based on a large set of predictors, with dynamic model averaging (DMA) and dynamic model selection (DMS). DMA/DMS allows not solely for coefficients to change over time, but also for changes in the entire forecasting model over time. DMA/DMS provides on average the best inflation forecasts with regard to alternative approaches (such as the random walk). DMS outperforms DMA. These results are robust for different sample periods and for various forecast horizons. The paper highlights common features between the USA and the EA. First, two groups of predictors forecast inflation: temporary fundamentals that have a frequent impact on inflation but only for short time periods; and persistent fundamentals whose switches are less frequent over time. Second, the importance of some variables (particularly international food commodity prices, house prices and oil prices) as predictors for consumer price index inflation increases when such variables experience large shocks. The paper also shows that significant differences prevail in the forecasting models between the USA and the EA. Such differences can be explained by the structure of these respective economies.

C-banding pattern and nucleolar organizer regions of Cynoglossus semilaevis Günther, 1873

The C-banding pattern and nucleolar organizer regions of the metaphase chromosomes of Cynoglossus semilaevis are reported. The interstitial regions in all chromosomes including the pair of sex chromosomes had positive C-bands, and the 6th and 12th pairs of chromosomes were entirely stained in most cases. Some chromosomes such as the 1st, 2nd, 7th, 8th, 9th and 10th pairs showed C-bands at centromeric or distal ends. The C-banding heretochromatin occupies 30.03% of the total chromosome surface in C. semilaevis,which is similar to that of amphibians such as Mixophyes fasciolatus (30.2%) and M. schevilli (20.7%), but is rather lower than that of cephalochordate Branchiostoma belcheri (54.3%). Silver staining revealed a single pair of nucleolar organizer regions (NORs) located in the telomeric regions of Chromosome 2. The association of NORs with heterochromatin observed in vertebrates also occurs in C. semilaevis as the telomeric regions of Chromosome 2 are always stained positively with C-banding.     

过渡金属乙酰丙酮配合物引发淀粉与烯基单体接枝共聚

研究了Ｍｎ（Ⅲ）、Ｃｏ（Ⅲ）、Ｃｒ（Ⅲ）和Ｖ（Ⅳ）的乙酰丙酮配合物引发淀粉与ＭＭＡ、ＡＮ、ＡＭ和ＡＡ接枝共聚合反应的引发活性。实验表明，４种引发体系中，Ｍｎ（ａｃａｃ）３的引发活性最佳，它可以有效地引发淀粉与上述４种单体的接枝共聚合反应，并获得较高的ＰＧ；Ｃｏ（ａｃａｃ）３和Ｃｒ（ａｃａｃ）３仅对水溶性烯基单体ＡＭ、ＡＡ有良好的引发活性；Ｖｏ（ａｃａｃ）２对４种单体的引发活性均较低。４种单体中，水
