Saari and Van Newenhizen (1987) misinterpret their findings about the indeterminacy of voting systems: far from being a vice, indeterminacy is a virtue in allowing voters to be more responsive to, and robbing them of the incentive to misrepresent, their preferences. The responsiveness of approval voting, in particular, means that the cardinal utilities that voters have for candidates can be reflected in voters' strategy choices, which ultimately translate into better social choices. Empirical data from a recent election support these claims, showing, among other things, that the Borda system, a determinate voting system favored by Saari and Van Newenhizen, is highly vulnerable to manipulation by strategic voters. 相似文献

Attenuated total reflection (ATR), also known as internal reflection spectroscopy (IRS), is a forensically accepted method for infrared (IR) analysis of pressure sensitive adhesive tapes. Advancements of ATR accessories in the last decade have provided the forensic examiner several ATR methods to choose from. These accessories offer a variety of ATR crystal choices with a variety of prices and capabilities. Four different types of pressure sensitive adhesive tapes including duct tape, electrical tape, packaging tape and office tape have been used to compare six different ATR methods. Each of the methods tested offers both benefits and limitaltions which must be considered for the type of sample to be analyze. The intent of this paper is to assist the reader in better understanding ATR techniques, the many differences among currently available ATR accessories and how the method is applied to the analysis of pressure sensitive adhesive tape. 相似文献

While the research base on implementation in child welfare has grown, applying implementation science to child welfare system change is still relatively new. There is a gap in knowledge of what factors are most important in different implementation stages and system contexts. This study examines 12 implementation keys that support building infrastructure, developing inter-organizational networks, and addressing contextual issues in child welfare system change initiatives in three states. Research questions address which keys are most important in different implementation stages, the major components and context of these keys during implementation, and the overlap between implementation keys. 相似文献

We consider the degree of ideological polarizationwithin and between the parties in the U.S. House ofRepresentatives for the period 1963–1996, using theGroseclose, Levitt and Snyder (1996) adjustment method for ADA and ACU scores to ensure over timecomparability of roll call voting data. We focusespecially on the median House member, since webelieve that change in the median offers a bettermeasure of the impact of the change in party controlthan does changes in the mean roll-call votingscore. Our data analysis makes two general points. First andforemost, when we looked at the change in the locationof the House median voter, we found a dramatic changeafter the Republicans gained a majority in the House in1994. After the Republicans became a majority in theHouse, the ADA median in the House in 1995–1996 was at24, far closer to the Republican median of 4 than tothe Democratic median of 83. The shift in medianfrom 1993–1994 to 1994–1995 involved a change of over 25points in one election – far and away the greatestsingle shift in ideology of the modern era. Incontrast, the mean changed only 1 point overthis same period. Second, for the three decades weinvestigated, we found three historical epochs vis a visthe relative locations of the ADA (or ACU) floormedian and the ADA (or ACU) floor mean in the U.S.House of Representatives – two inflection points in1983 and 1994 which are related to trends in regionalrealignment. 相似文献

In the standard Downsian model, voters are assumed to choose parties based on the extent of ideological proximity between the voter's own position and that of the party. Yet it is also well known that there are rationalization and projection effects such that voters tend to misestimate the policy platforms of candidates or parties to which they are sympathetic by overstating the correspondence between those positions and the voter's own preferences (see, e.g., Markus & Converse 1979; Granberg & Brent 1980; Granberg & Holmberg 1988; Merrill & Grofman 1999). Here we follow insights in the psychological literature on persuasion (Sherif & Hovland 1961; Parducci & Marshall 1962) by distinguishing between assimilation and contrast effects. Assimilation refers to shortening the perceived ideological distance between oneself and parties one favors; contrast refers to exaggerating the distance to parties for which one does not intend to vote. Using survey data on voter self–placements and party placements on ideological scales for the seven major Norwegian parties, five major French parties, and two major American parties we show that both assimilation and contrast effects are present in each country to a considerable degree.We also investigate the possible effects of randomness in party placement and scale interpretation – effects that can easily be confounded with assimilation but not so easily with contrast. 相似文献

Basic Downsian theory predicts candidate convergence toward the views of the median voter in two-candidate elections. Common journalistic wisdom, moreover, leads us to expect these centripetal pressures to be strongest when elections are expected to be close. Yet, the available evidence from the US Congress disconfirms this prediction. To explain this counterintuitive result, we develop a spatial model that allows us to understand the complex interactions of political competition, partisan loyalties, and incentives for voter turnout that can lead office-seeking candidates, especially candidates in close elections, to emphasize policy appeals to their voter base rather than courting the median voter. 相似文献
