A burgeoning literature shows that campaigns exert substantial influence on voters by priming selected policy issues. We extend this research by offering a framework that (1) incorporates a model of campaign image priming and (2) describes the politi

Why do presidents talk at length about some policy issues, while ignoring others? Which issues do presidents emphasize in their public rhetoric, how do they talk about them, why, and with what effects? How do they divide their messages between oral a

Introduction: Typically found in young women, solid pseudopapillary tumors of the pancreas (SPTP) are part of the differential diagnosis for solid and cystic neoplasms of the pancreas. SPTP may cause diagnostic confusion when presenting with massive

η2-Phosphinocarbebe complexes of tungsten show a different behaviour towards anionic nucleophiles. The cationic η2-phosphinocarbene complex [ Cp(CO ) 2 W=C(Tol)P Ph 2 ][ BPh 4 ] reacts with the thiophenolate anion PhS− via carbonyl substitution,

η3-Phosphinoketene complexes of tungsten Cp(CO)ClW [η3-P(Ph2)-C(R)=C=O] (R=Me, Ph) react with hydrogen chloride under protonation of the ketene oxygen atom converting the ketene into a new cyclobutenol system. The products have been characterized b
