The Role of Media for Inflation Forecast Disagreement of Households and Professional Forecasters

This paper investigates the effects of media coverage and macroeconomic conditions on inflation forecast disagreement of German households and professional forecasters. We adopt a Bayesian learning model in which media coverage of inflation affects forecast disagreement by influencing information sets as well as predictor choice. Our empirical results show that disagreement of households depends on the content of news stories (tone) but is unaffected by reporting intensity (volume) and by the heterogeneity of story content (information entropy). Disagreement of professionals does not depend on media coverage. With respect to the influence of macroeconomic variables we provide evidence that disagreement of households and professionals primarily depends on the current rate of inflation

Biosintesi della siringomicina: correlazione tra la struttura e la funzionalità biosintetica della proteina SyrC

Viene presentato uno studio di relazione struttura-attività della proteina SyrC, codificata all'interno del cluster biosìntetico della siringomicina, un lipopeptide prodotto dal batterio Pseudomonas syringae pv. syringae. Mutazione sito-diretta della Cys167 e le modifiche all'N-terminale annullano la funzione della proteina. Gli effetti delle modifiche sono stati valutati mediante complementazione funzionale di un ceppo mutante di Pseudomonas syringae pv. syringae nel quale era inattivato il gene syrC, misurando la capacità delle forme mutate di SyrC di ripristinare la produzione della siringomicina

[Carotid body tumors: an analysis of 10 cases]. FT Tumori del glomo carotideo: analisi di 10 casi.

Some problems of carotid body tumors regarding diagnosis and treatment are still controversial. From 1988 to 1998 we operated on 10 cervical paragangliomas in our Division of Vascular Surgery of Bari University. Three were bilateral and 2 were II Shamblin class. Seven tumors were considered familiar type (5 patients in the same family). Subadventitial dissection was performed in all cases after 4 vessel angiographies and Echo-dopplers. No complications occurred during the operation or post-operatively. Operative bleeding was reduced significantly by the use of subadventitial dissection which was accomplished in short times, thus avoiding more complicated and even hazardous techniques like clamping, sectioning or ligatures of the external carotid artery
