标题： B-Call: Integrating Ideological Position and Political Cohesion in Legislative Voting Models

摘要： 本文结合了政治科学研究的两个重要领域：测量个体意识形态立场和凝聚力。 尽管这两种方法有助于分析立法行为，但目前尚无统一的模型能够整合这些维度。 为了填补这一空白，本文提出了一种称为B-Call的方法，将意识形态定位与投票凝聚力相结合，将投票视为随机变量。 该模型使用美国、巴西和智利立法机构的表决数据进行了实证验证，这些数据代表了不同的立法动态。 分析旨在捕捉投票和立法行为的复杂性，从而得出一个二维指标。 本研究解决了当前立法投票模型中的不足，特别是在政党控制有限的背景下。 显示英文摘要

摘要： This paper combines two significant areas of political science research: measuring individual ideological position and cohesion. Although both approaches help analyze legislative behaviors, no unified model currently integrates these dimensions. To fill this gap, the paper proposes a methodology called B-Call that combines ideological positioning with voting cohesion, treating votes as random variables. The model is empirically validated using roll-call data from the United States, Brazil, and Chile legislatures, which represent diverse legislative dynamics. The analysis aims to capture the complexities of voting and legislative behaviors, resulting in a two-dimensional indicator. This study addresses gaps in current legislative voting models, particularly in contexts with limited party control.
