Measuring ‘Closeness’ In 3-Candidate Elections: Methodology And An Application To Strategic Voting, Daniel Kselman, Emerson Niou, Austin Horng-En Wang Oct 2020

Measuring ‘Closeness’ In 3-Candidate Elections: Methodology And An Application To Strategic Voting, Daniel Kselman, Emerson Niou, Austin Horng-En Wang

Political Science Faculty Research

Past research suggests that voter behavior is influenced by perceptions of electoral competitiveness. For example, when an election is perceived to be close, voters will be more likely to turnout and/or cast strategic votes for their second-most preferred candidate. Operationalizing electoral competitiveness in three-candidate elections presents previously unrecognized methodological challenges. This paper first shows that many past strategies for measuring ‘closeness’ in three-candidate contests have violated at least one of three basic properties that any such measure should satisfy. We then propose a new measurement grounded in probability ratios, and prove formally that ratio-indices satisfy these axiomatic criteria. Empirical analyses …


The Political Economy Of Vermont’S Abortion Bill, Shishir Shakya, Elham Erfanian, Alexandre R. Scarcioffolo Oct 2020

The Political Economy Of Vermont’S Abortion Bill, Shishir Shakya, Elham Erfanian, Alexandre R. Scarcioffolo

Regional Research Institute Working Papers

Public choice literature divides the rationality of voting between instrumental and expressive. In this paper, we take the Vermont legislature in passing the H. 57 bill as a case to explain some of the determinants of expressive voting empirically. The H.57 bill declares that no government entity can interfere with, or restrict, a consenting individual’s right to abortion care across the entire gestation period. However, the bill has not changed the previously states quo of the state towards abortion rights. Thus, it creates a situation in which we can analyze the legislator’s voting behavior through the lens of expressive voting …


Agent-Based Modelling Of Values: The Case Of Value Sensitive Design For Refugee Logistics, Christine Boshuijzen-Van Burken, Ross J. Gore, Frank Dignum, Lamber Royakkers, Phillip Wozny, F. Leron Shults Oct 2020

Agent-Based Modelling Of Values: The Case Of Value Sensitive Design For Refugee Logistics, Christine Boshuijzen-Van Burken, Ross J. Gore, Frank Dignum, Lamber Royakkers, Phillip Wozny, F. Leron Shults

VMASC Publications

We have used value sensitive design as a method to develop an agent-based model of values in humanitarian logistics for refugees. Schwartz’s theory of universal values is implemented in the model in such a way that agents can make value trade-offs, which are operationalized into a measure of refugee wellbeing and a measure of public opinion about how the refugee logistics is being handled. By trying out different ‘value scenarios’, stakeholders who are responsible for, or involved in refugee logistics can have insights into the effects of various value choices. The model is visualized and made usable as a platform …


Governance By Other Means: Rankings As Regulatory Systems, Judith G. Kelley, Beth A. Simmons Jun 2020

Governance By Other Means: Rankings As Regulatory Systems, Judith G. Kelley, Beth A. Simmons

All Faculty Scholarship

This article takes the challenges of global governance and legitimacy seriously and looks at new ways in which international organizations (IOs) have attempted to ‘govern’ without explicit legal or regulatory directives. Specifically, we explore the growth of global performance indicators as a form of social control that appears to have certain advantages even as states and civil society actors push back against international regulatory authority. This article discusses the ways in which Michael Zürn's diagnosis of governance dilemmas helps to explain the rise of such ranking systems. These play into favored paradigms that give information and market performance greater social …


Decision Tree For Predicting The Party Of Legislators, Afsana Mimi May 2020

Decision Tree For Predicting The Party Of Legislators, Afsana Mimi

Publications and Research

The motivation of the project is to identify the legislators who voted frequently against their party in terms of their roll call votes using Office of Clerk U.S. House of Representatives Data Sets collected in 2018 and 2019. We construct a model to predict the parties of legislators based on their votes. The method we used is Decision Tree from Data Mining. Python was used to collect raw data from internet, SAS was used to clean data, and all other calculations and graphical presentations are performed using the R software.


Testing For Negative Spillovers: Is Promoting Human Rights Really Part Of The “Problem”?, Anton Strezhnev, Judith G. Kelley, Beth A. Simmons Feb 2020

Testing For Negative Spillovers: Is Promoting Human Rights Really Part Of The “Problem”?, Anton Strezhnev, Judith G. Kelley, Beth A. Simmons

All Faculty Scholarship

The international community often seeks to promote political reforms in recalcitrant states. Recently, some scholars have argued that, rather than helping, international law and advocacy create new problems because they have negative spillovers that increase rights violations. We review three mechanisms for such spillovers: backlash, trade-offs, and counteraction and concentrate on the last of these. Some researchers assert that governments sometimes “counteract” international human rights pressures by strategically substituting violations in adjacent areas that are either not targeted or are harder to monitor. However, most such research shows only that both outcomes correlate with an intervention—the targeted positively and the …


Partisan Voting On The California Supreme Court, Mark P. Gergen, David A. Carrillo, Benjamin M. Chen, Kevin M. Quinn Jan 2020

Partisan Voting On The California Supreme Court, Mark P. Gergen, David A. Carrillo, Benjamin M. Chen, Kevin M. Quinn

Faculty Articles

When did ideology become the major fault line of the California Supreme Court? To answer this question, we use a two-parameter item response theory (IRT) model to identify voting patterns in non-unanimous decisions by California Supreme Court justices from 1910 to 2011. The model shows that voting on the court became polarized on recognizably partisan lines beginning in the mid-1900s. Justices usually did not vote in a pattern that matched their political reputations and party affiliation during the first half of the century. This began to change in the 1950s. After 1959 the dominant voting pattern is partisan and closely …


The Rawlsian Mirror Of Justice, Jessica Flanigan Jan 2020

The Rawlsian Mirror Of Justice, Jessica Flanigan

Jepson School of Leadership Studies articles, book chapters and other publications

Libertarians(like me) generally disagree with orthodox Rawlsians (like Samuel Freeman) about whether Rawlsian principles of distributive justice are compatible with libertarianism.1In this essay, I set out to explain why. In section 1, I describe the problem, which is essentially that libertarians think the Rawlsian framework does not rule out anti-statist, capitalist, and broadly libertarian approaches to distributive justice and orthodox Rawlsians think that it does. I propose that this problem arises because the Rawlsian framework is underspecified in two ways. First, the Rawlsian framework has a lot of moving parts, so people with different pre-theoretical intuitions can use …


Impacts Of Media Communication To Motivate State Level Policy Action: The Case Of The Colorado River Basin, Abigail Rader Jan 2020

Impacts Of Media Communication To Motivate State Level Policy Action: The Case Of The Colorado River Basin, Abigail Rader

CSB/SJU Distinguished Thesis

The cultivation of life within the American Southwest would not have been possible without the Colorado River Basin. The water in the basin today maintains 40 million people and one-twelfth the American economy. As a result of the significance of this river, the Colorado is one of the most regulated waters in the world, yet drought concerns continue to proliferate due to climate change. Drawing from communication and political science literature, the media have frequently been cited as impacting the policy agenda, particularly local media. This paper addresses how the frequency of The Denver Post news reporting and its framing …
