In Professor Horowitz’s rejoinders (2004, 2006) to Fraenkel and Grofman (2004, 2006a), he mischaracterizes our formal results, retreats from previous claims about the conditions for the alternative vote electoral system to generate centripetal outcomes, renders explicit his dubious assumptions about voter behavior in divided societies, and greatly exaggerates the global evidence in support of pro-moderation outcomes under the alternative vote. Here we respond to Horowitz's (2004), criticism in this journal of the formal model of Fraenkel and Grofman (2004) and to the broader defense in Horowitz (2006) of majoritarian vote pooling arrangements as means of mitigating ethnic conflict in deeply divided societies. 相似文献

Grofman et al. (forthcoming) find thatparty leaders in the U.S. House ofRepresentatives tend to be more extremethan the median member of their party, andthat they tend to come from the party'sideological ``heartland'' between the medianand the mode. This paper shows that if thedistribution of preferences is skewed (asis the case with both parties in theHouse), then we should expect sequentialelimination elections to choose on averageleaders between the median and modalpositions. We show that this is the casewhether or not the party is factionalized. 相似文献

In 0.22 caliber rimfire ammunition, the primer often contains lead or lead and barium compounds. As residues from these primers do not contain lead, barium, and antimony, they cannot be uniquely classified as gunshot residue (GSR) under ASTM designation E 1588-95. In many types of 0.22 caliber rimfire ammunition, the cartridge contains a primer sensitized with glass. In this paper we describe a previously unreported type of GSR particle consisting of glass fused with other primer components. As there appear to be few potential environmental or occupational sources of particles composed of lead and barium compounds fused to glass, particularly borosilicate glass, these particles may have high evidential value. Scanning electron microscopy with energy dispersive X-ray detection (SEM-EDX) and time-of-flight secondary ion mass spectrometry (TOF-SIMS) were evaluated for the characterization of glass-containing GSR particles. The occurrence of glass-containing GSR particles was established in the residue from various brands of 0.22 caliber ammunition, and several sub-types were identified. 相似文献
