高效的可证安全的部分盲签名(英文)

部分盲签名通过在最终的签名数据中包含签名者和用户协商一致的公用信息(签名发布日期,电子货币的金额)来扩展了盲签名的概念。该文在随机预言机模型下提出了一个高效的可证安全的部分盲签名方案,该方案利用一个公开可行的算法提前计算出将要在随后的部分盲签名协议中用到的公钥和私钥,因此该方案Okamoto-Schnorr盲签名方案具有相同的安全性,并且不会造成额外的系统开销。

Choosing Choices: Agenda Selection With Uncertain Issues

We study selection rules: voting procedures used by committees to choose whether to place an issue on their agenda. At the selection stage of the model, committee members are uncertain about their final preferences. They only have some private information about these preferences. We show that voters become more conservative when the selection rule itself becomes more conservative. The decision rule has the opposite effect. We compare these voting procedures to the designation of an agenda setter among the committee and to a utilitarian social planner with all the ex interim private information.

Generalized estimating equations for mixtures with varying concentrations

A finite mixture model is considered in which the mixing probabilities vary from observation to observation. A parametric model is assumed for one mixture component distribution, while the others are nonparametric nuisance parameters. Generalized estimating equations (GEE) are proposed for the semi‐parametric estimation. Asymptotic normality of the GEE estimates is demonstrated and the lower bound for their dispersion (asymptotic covariance) matrix is derived. An adaptive technique is developed to derive estimates with nearly optimal small dispersion. An application to the sociological analysis of voting results is discussed.

Meta-cognition and resistance to political persuasion: evidence from a three-wave panel study

ABSTRACT

We investigate the temporal course of meta-cognition and resistance processes following exposure to counter-attitudinal information in the 2012 Presidential election. Using a unique 3-wave survey panel design, we tracked eligible voters during the last months of the 2012 campaign and experimentally manipulated exposure to negative political messages targeting Barack Obama and Mitt Romney on an online platform. As predicted, we found that politically unengaged (vs. engaged) individuals were less likely to counter-argue a message attacking their favored candidate. Resistance, in turn, led to increased attitudinal certainty, polarization, and correspondence with actual voting behavior over the course of the campaign. These findings provide the first analysis of the longitudinal effects of meta-cognitive processes underlying persuasion for real-world attitude change and behavior.     

A longitudinal test of the gender turnover model among U.S. House and Senate members

This study builds on previous research by examining the impact of gender when predicting roll call voting behavior in the U.S. House and the U.S. Senate over several recent congresses. In order to unearth gender effects, it employs a longitudinal design based on turnover in the membership of both the House and the Senate. Through a comparison of the voting records of members of Congress representing the same geographic territory it holds constituency constantly while allowing for gender and party to vary. It does so with models including dependent variables that measure roll call ideology and support for women's issues exhibited in the voting records of members in both institutions. The results show that male and female members in each chamber representing the same constituency amass virtually indistinguishable voting records on the liberal-conservative policy dimension. However, on votes dealing with issues of concern to women, female senators tend to be more supportive than the male senators they replace and male senators tend to be less supportive than the female senators they replace.     

Groups or Gatherings? Sources of Political Engagement in 19th Century American Cities

There is broad agreement that citizen participation is critical for successful democracy. Recently, scholars have linked such political participation with the notion of social capital—community-level resources, such as trust, norms, and networks, that foster collective action. Much uncertainty remains regarding the sources of social capital, however. Here we examine two different features of community life that are believed to nurture social capital, and political participation in turn: public venues where relative strangers can meet anonymously, socialize, and share information and opinions (i.e., venues for informal interaction); and venues for organized exchange between familiars, such as voluntary organizations and social clubs. Using quantitative data from America's largest cities at the end of the 19th century, we examine the relationship between both supposed sources of social capital and respective rates of voter participation. We find little support for the role of informal interaction in fostering an active and engaged citizenry. We do, however, find evidence that citizen participation was related to some types of associationalism (or organized exchange). In particular, associations that fostered high levels of mutual interdependence among members seemed the most strongly linked to higher levels of political participation.
