A minimax procedure for electing committees   总被引:1,自引:0,他引:1  
A new voting procedure for electing committees, called the minimax procedure, is described. Based on approval balloting, it chooses the committee that minimizes the maximum Hamming distance to voters’ ballots, where these ballots are weighted by their proximity to other voters’ ballots. This minimax outcome may be diametrically opposed to the outcome obtained by aggregating approval votes in the usual manner, which minimizes the sum of the Hamming distances and is called the minisum outcome. The manipulability of these procedures, and their applicability when election outcomes are restricted in various ways, are also investigated. The minimax procedure is applied to the 2003 Game Theory Society election of a council of 12 new members from a list of 24 candidates. By rendering outlying voters less influential and not antagonizing any voters too much, it arguably would have produced a committee more representative of the interests of all voters than the minisum committee that was elected.  相似文献

Use of Force     
Waddington  P. A. J. 《Policing》2007,1(3):249-251
This issue of Policing: A Journal of Policy and Practice, isdevoted principally to the use of force, a topic that has dominatedacademic debate and preoccupied practitioners. For academics,the question is: what distinguishes police officers and theorganisations in which they operate from others, particularlythose growing legions of private security operatives, un-swornpolice auxiliaries, and sundry officials with law enforcementpowers? The orthodox answer is that the police enjoy a ‘monopolyof legitimate force’ over their fellow citizens (a viewthat has its origins in the pioneering work of Bittner, 1970).That orthodoxy has increasingly been criticised in the faceof the obvious fact that bouncers, store detectives, securityguards of all kinds, and many others also exercise ‘legitimateforce’ in ejecting drunken customers from pubs and clubs,apprehending shoplifters, and defending  相似文献

Abstract.  This article examines a model of the domestic political economy of subjective employment insecurity in advanced industrial societies. Based on data on people's attitudes toward their job as well as levels of and kinds of social protection collected in 15 OECD countries, it shows that there are distinct manifestations of job insecurity that are affected differently by distinct aspects of social protection programs. While the analysis shows that social protection measures reduce employment insecurity, it also reveals that overall levels welfare state generosity do not have any systematic effect on whether workers feel secure. The article's findings suggest the need to decompose the different components of employment insecurity as well as disaggregate national systems of social protection when examining the impact of welfare states on job insecurity.  相似文献

Detective stories take place mainly in two settings, constantly changing, many faceted big cities filled with strangers, and stable, fairly homogeneous, innocent small towns whose members know one another. The differences in each clarify the qualities of the other. In solving the mystery of the small town, the detective provides moral instruction and restores the town’s innocence. In solving the mystery in the big city the detective reveals the city as part of the mystery and provides the reader with temporary orientation to the city. Mysteries have grown with the growth of the cities and now appear in every country of the world. Harold J. Bershady is an emeritus Professor of Sociology at the University of Pennsylvania. His most recent book, edited with Renée Fox and Victor Lidz, is After Parson: A Theory of Action for the 21st Century, published by Russell Sage Press, 2005.  相似文献

Two features of citizen response to Congress can be taken as grounds for concern. First, Americans know relatively little about Congress, and especially about congressional procedures and policy output. Second, Congress typically emerges as the least respected political institution. Although these matters are troubling when viewed individually, more disturbing is the dilemma posed when knowledge and attitudes toward Congress are viewed in tandem. It appears that citizens who know Congress the best like Congress the least. Consequently, a sophisticated polity and a well-respected legislature seem fundamentally incompatible. This article seeks to resolve this dilemma, contending that there is nothing about knowledge per se that leads citizens to view Congress unfavorably. Rather, differences in knowledge levels alter the considerations citizens bring to bear when evaluating Congress, with the best-informed individuals constructing judgments on the basis of the most relevant Congress-specific criteria while less knowledgeable citizens employ readily available but more peripheral criteria.  相似文献

Campaigns rely upon both paid and volunteer phone calls to mobilize voters. Past field experiments show calls from volunteers to increase turnout and paid calls to be wholly ineffective. This article argues that the quality of phone calls rather than the presence or absence of a payroll explains this regularity. Three aspects of quality are considered: monitoring pace and interactivity, timing, and message. A fully randomized field experiment with over 100,000 subjects comparing professional and volunteer phone banks simultaneously was conducted during the 2002 congressional elections to test this hypothesis. The experiment discovers precisely the opposite relationship of prior research: effective professional phone banks and inefficient volunteer phone calls. The experiment also finds substantial temporal decay. The specific messages appear less important than tone or timing. The implications for the role of campaign consultants, replacing social capital, voter psychology, and the capacities of civic organizations are discussed.  相似文献

Why does the influence of Congressional parties fluctuate over time? Building on prevailing answers, we develop a model, Strategic Party Government, which highlights the electoral motives of legislative parties and the strategic interaction between parties. We test this theory using the entire range of House and Senate party behavior from 1789 to 2000 and find that the strategic behavior of parties complements members' preferences as an explanation for variation in party influence. Specifically, the strongest predictors of one party's voting unity are the unity of the opposing party and the difference between the parties in the preceding year. Moreover, we find strong links between party behavior in Congress and electoral outcomes: an increase in partisan influence on legislative voting has adverse electoral costs, while winning contested votes has electoral benefits.  相似文献

We investigate how aspects of "civil service" systems of personnel management interact with bureaucratic discretion to create expert bureaucracies populated by policy-motivated agents. We construct a dynamic model in which bureaucrats may invest in (relationship-specific) policy expertise and may or may not be interested in policy choices per se. The legislature makes sequentially rational grants of discretion, which serve as incentives for expertise investment and continued service only for policy-motivated bureaucrats. Bureaucratic policy preferences and the legislature's agency problem vis-à-vis bureaucracies develop endogenously in the model. Bureaucratic expertise can be supported in equilibrium only at a cost of its politicization; "neutral competence" is inconsistent with strategic incentives of bureaucrats. We identify several conditions that support the development of an expert bureaucracy in equilibrium, including security of job tenure and control over policy issues for policy-motivated bureaucrats.  相似文献

Some scholars argue that the author of the majority opinion exercises the most influence over the Court's opinion-writing process and so can determine what becomes Court policy, at least within the limits of what some Court majority finds acceptable. Other students of the Court have suggested that the Court's median justice effectively dictates the content of the majority opinion: whatever policy the median justice most wants, she can get. We test these competing models with data on Supreme Court decision making during the Burger Court (1969–86). While we find substantial evidence for both models, the agenda control model gains greater support. This suggests that opinions on the Court on each case are driven, in general, by the interaction of three key variables: the policy preferences of the majority opinion author, the policy preferences of the median justice, and the location of the legal status quo .  相似文献
