A Pca-Ols Model For Assessing The Impact Of Surface Biophysical Parameters On Land Surface Temperature Variations, Mohammad Karimi Firozjaei, Seyed Kazem Alavipanah, Hua Liu, Amir Sedighi, Naeim Mijani, Majid Kiavarz, Qihao Weng Jan 2019

A Pca-Ols Model For Assessing The Impact Of Surface Biophysical Parameters On Land Surface Temperature Variations, Mohammad Karimi Firozjaei, Seyed Kazem Alavipanah, Hua Liu, Amir Sedighi, Naeim Mijani, Majid Kiavarz, Qihao Weng

Political Science & Geography Faculty Publications

Analysis of land surface temperature (LST) spatiotemporal variations and characterization of the factors affecting these variations are of great importance in various environmental studies and applications. The aim of this study is to propose an integrated model for characterizing LST spatiotemporal variations and for assessing the impact of surface biophysical parameters on the LST variations. For this purpose, a case study was conducted in Babol City, Iran, during the period of 1985 to 2018. We used 122 images of Landsat 5, 7, and 8, and products of water vapor (MOD07) and daily LST (MOD11A1) from the MODIS sensor of the …

Legislative Committee Systems: A Design Perspective, Chase Stoddard Oct 2018

Legislative Committee Systems: A Design Perspective, Chase Stoddard

Indiana Journal of Constitutional Design

Committees are the defining characteristic of the modern legislature. While the centrality and study of party politics goes back further than committee politics, the focus on committee systems emerged over the course of the twentieth century, and legislatures could not function as we understand them without this mechanism. The United States Congressional committee system is the most studied system, yet virtually every country utilizes a committee system of some sort within its legislature. Despite their ubiquity in and centrality to the operations of legislatures, committees remain insufficiently studied, especially outside of the United States. The existing body of work tends …


Process-Tracing Research Designs: A Practical Guide, Jacob Ricks, Amy H. Liu Oct 2018

Process-Tracing Research Designs: A Practical Guide, Jacob Ricks, Amy H. Liu

Research Collection School of Social Sciences

Process-tracing has grown in popularity among qualitative researchers. However, unlike statistical models and estimators—or even other topics in qualitative methods—process-tracing is largely bereft of guidelines, especially when it comes to teaching. We address this shortcoming by providing a step-by-step checklist for developing a research design to use process-tracing as a valid and substantial tool for hypothesis testing. This practical guide should be of interest for both research application and instructional purposes. An online appendix containing multiple examples facilitates teaching of the method.

Conceptualizing And Measuring Women’S Political Leadership: From Presence To Balance, Devin K. Joshi, Ryan Goehrung Sep 2018

Conceptualizing And Measuring Women’S Political Leadership: From Presence To Balance, Devin K. Joshi, Ryan Goehrung

Research Collection School of Social Sciences

This article conceptualizes an innovative understanding and measurement of women's political leadership, theoretically justifies its application, and analyzes contemporary variation in its patterns through comparative case studies. In recent years, scholars of comparative government have studied with great interest the election of female prime ministers and presidents (e.g., Derichs and Thompson 2013; Jalalzai 2013) and cross-national variation in female members of parliaments (MPs) and cabinets (e.g., Bauer and Tremblay 2011; Paxton and Hughes 2017; Suraj, Scherpereel, and Adams 2014). Yet, when it comes to regions beyond Europe and the Americas, comparative empirical analysis of women's political leadership (WPL) across national-level …

Measuring Public Utilization Perception Potential Of Unmanned Aircraft Systems, Julius Keller, Daniel Kwasi Adjekum, Bortiorkor Nii Tsui Alabi, Brian Kozak Jul 2018

Measuring Public Utilization Perception Potential Of Unmanned Aircraft Systems, Julius Keller, Daniel Kwasi Adjekum, Bortiorkor Nii Tsui Alabi, Brian Kozak

International Journal of Aviation, Aeronautics, and Aerospace

The integration of Unmanned Aircraft Systems (UAS) into the National Air Space (NAS) in recent times has been met by mixed public responses. The paper establishes four constructs each of which encapsulates multiple backgrounds and concerns of the stakeholders: functional knowledge, utilization trust, operational integration support, and safety risk-benefits. The paper hypothesizes that these constructs can serve as underlying components for a research instrument namely, the Public Utilization Perception Potential (PUPP) which can be used to assess the opinions of the public on UAS integration into NAS. Responses from the public on items in a beta-tested survey instrument were analyzed …

A Challenge To Socio-Ecological Resilience: Community Based Resource Management Organizations’ Perceptions And Responses To Cannabis Cultivation In Northern California, Yvonne Everett May 2018

A Challenge To Socio-Ecological Resilience: Community Based Resource Management Organizations’ Perceptions And Responses To Cannabis Cultivation In Northern California, Yvonne Everett

Humboldt Journal of Social Relations

Local nonprofit organizations in the Pacific Northwest have stepped up to fill a leadership void in forest management since the Timber Wars of the 1980s and 1990s. Community based resource management groups (CBRM) have focused on stewardship of ecosystem services, and leading efforts to employ local workers to restore forest ecosystems and watershed functions. In Northern California, even as CBRM capacity has grown since the Timber Wars, a new transformative challenge threatens community and landscape adaptive capacity. Cannabis cultivation, which can have significant environmental and social impacts, has become a pervasive economic driver. I used interviews to explore CBRM leaders’ …


Poison Pills: How Subtle Differences In Processes, Public Opinion, And Leadership Doomed The American Health Care Act And Passed The Affordable Care Act, Zachary Eichten May 2018

Poison Pills: How Subtle Differences In Processes, Public Opinion, And Leadership Doomed The American Health Care Act And Passed The Affordable Care Act, Zachary Eichten

All College Thesis Program, 2016-2019

In 2009, the Patient Protection and Affordable Care Act became law. This was possible because the Democratic Party had a majority in both branches of Congress and control in the executive branch. In 2017, the American Health Care Act failed to become law, despite the fact that the Republicans controlled Congress and the presidency. What factors explain the different outcomes? Why was one able to pass, but not the other? This study presents a framework for explaining these different outcomes by exploring the impact of the legislative process, the role of public opinion, and the impact of polarization as factors …


Impact Of A Charter School On House Capitalization In A Title I Environment, Mark Haskew May 2018

Impact Of A Charter School On House Capitalization In A Title I Environment, Mark Haskew

Masters Theses

This study used a mixed-methods approach to determine whether a charter school could influence house capitalization and whether it could induce some families to stay in the school district. It examined home sale values around a charter school in an area covered by underperforming Title I schools. There was a positive but statistically insignificant change in a pre/post comparison of home sale prices, but the increase was consistent with nearby control schools. However, a survey of charter school families found that 25 percent would have left the district had they not been enrolled at the charter school. A plurality said …


Political Accountability And Determinants Of Governance Under Principal-Agent Theory, Matthew Bluem May 2018

Political Accountability And Determinants Of Governance Under Principal-Agent Theory, Matthew Bluem

Dissertations

This study examines the theory that quality of governance is largely dependent upon political accountability, and that the effect of political accountability on governance varies based on three main determinants: level of democracy, level of information available to the public, and diversification of the economy (Adserà et al. 2003). With quality of governance, represented by the World Bank’s World Governance Indicators (WGI), as the dependent variable, this study considers how these three independent variables, and several control variables, affect governance quality. Incorporating data from 2010 – 2015 for 143 countries in both cross-sectional OLS and fixed effects panel regression analysis, …


Predicting How U.S. Counties Will Vote In Presidential Elections Through Analysis Of Socio-Economic Factors, Voting Heuristics, And Party Platforms, Joseph Stoffa, Randall Lisbona, Christopher Farrar, Mike Martos Apr 2018

Predicting How U.S. Counties Will Vote In Presidential Elections Through Analysis Of Socio-Economic Factors, Voting Heuristics, And Party Platforms, Joseph Stoffa, Randall Lisbona, Christopher Farrar, Mike Martos

SMU Data Science Review

In this paper, it is proposed that voters, devoid of any pressing concerns that could be addressed at the federal level, will tend to vote by their ideology for their preferred party. However, given pressing concerns, they will vote for whichever party can address these concerns despite party affiliation. This hypothesis is extended to the county level by assuming counties can be defined as the aggregate of their voting residence and as such their behavior can be predicted by considering their past voting history, socioeconomic makeup, and party platform.


The Effect Of Belief Of Victory On Third-Party Vote Share: Duverger's Law & Why Evan Mcmullin Lost Utah In 2016, John Geilman Apr 2018

The Effect Of Belief Of Victory On Third-Party Vote Share: Duverger's Law & Why Evan Mcmullin Lost Utah In 2016, John Geilman

Undergraduate Honors Theses

A key reason Duverger’s Law is valid is a voter’s belief that a third-party does not have a chance at winning an election in a “first past the post” electoral system. Duverger’s Law has traditionally been explained through two reasons—a mechanical factor and a psychological factor. The mechanical factor focuses on aspects of electoral systems that work against third parties, while the psychological factor focuses on what voters think and feel about third parties. In the 2016 presidential election in the United States, voters in the state of Utah demonstrated that their perception of the electability of a third-party candidate …

The Shrinking Center: When Are Centrists More Effective Lawmakers?, Benjamin Pontz Apr 2018

The Shrinking Center: When Are Centrists More Effective Lawmakers?, Benjamin Pontz

Student Publications

Legislative effectiveness is an inherently amorphous -- even subjective -- concept. Yet, arguably, it is among the most important considerations when evaluating the performance of members of Congress. Using Volden and Wiseman's index, the Legislative Effectiveness Score (LES), I evaluate when ideology informs or predicts effectiveness in passing laws, which I conceptualize as the fundamental role of legislators. In particular, I assess the extent to which centrists are more or less effective than their more partisan peers. I find that, while the number of centrists has declined precipitously, their ideology does not -- at least at the broadest level -- …


Challenges To The Study Of Long Wars, Zachary C. Shirkey Mar 2018

Challenges To The Study Of Long Wars, Zachary C. Shirkey

Publications and Research

Rationalist, psychological, and domestic politics approaches have all generated internally consistent, plausible explanations for long wars. But sorting out which of these explanations is most valid is quite difficult, because definitional questions bedevil the study of war duration, and more importantly, because it is very hard to evaluate the evidence for competing explanations of war duration. The latter difficulty arises for three reasons. First, many state behaviors are consistent with multiple, competing explanations of long wars. Second, in most states, multiple people play important roles in crafting foreign policies, meaning different leaders may have different primary motives for continuing a …


Coalitions Matter: Citizenship, Women, And Quota Adoption In Africa, Alice J. Kang, Aili Mari Tripp Mar 2018

Coalitions Matter: Citizenship, Women, And Quota Adoption In Africa, Alice J. Kang, Aili Mari Tripp

Department of Political Science: Faculty Publications

We provide new theory and evidence of the role of domestic women’s coalitions in the adoption of gender quotas. Previous research has shown the importance of women’s movements to policy change. We show that specific types of mobilization, often multiethnic in character, are a more precise way of describing these influences. Using a new dataset of coalitions in 50 countries in Africa (1989–2014), we first examine where coalitions are likely to emerge. Controlling for factors that correlate with their formation, we find that when domestic women’s organizations form a coalition for quotas, governments are more likely to adopt them and …

Department of Sociology: Faculty Publications

The 2016 presidential election was a jarring event for polling in the United States. Preelection polls fueled high-profile predictions that Hillary Clinton’s likelihood of winning the presidency was about 90 percent, with estimates ranging from 71 to over 99 percent. When Donald Trump was declared the winner of the presidency, there was a widespread perception that the polls failed. But did the polls fail? And if so, why? Those are among the central questions addressed by an American Association for Public Opinion Research (AAPOR) ad hoc committee. This paper presents the committee’s analysis of the performance of preelection polls in …

The Student Debt Crisis And Political Polarization In The Millennial Generation, Dylan Wallace Jan 2018

The Student Debt Crisis And Political Polarization In The Millennial Generation, Dylan Wallace

Honors Undergraduate Theses

According to the Pew Research Center, the modern wave of political polarization began in 1994, and is the strongest today than it has ever been during the 23-year period. (2007) Polarization in the US party system is evidenced by several factors including: growing consistent partisan views, partisan antipathy, ideological bubbles, growing difference in preferences, a shrinking political center, and the lack of political compromise. (Pew Research Center 2014) The question I attempt to answer in this thesis is on the factors associated with political polarization within the millennial generation. One of the most pressing issues to this generation is what …


The Incarceration Nation: Interpreting The United States Imprisonment Rate, Robert Sharp Jan 2018

The Incarceration Nation: Interpreting The United States Imprisonment Rate, Robert Sharp

Williams Honors College, Honors Research Projects

This research paper begins by establishing the importance of studying the United States’ incarceration rate. Overall mass imprisonment and racial disparities in sentencing are two of the main concerns when discussing this issue. Previously published literature has indicated various contributory factors to the racial disparity in sentencing, such as judge’s discretion, educational attainment, and policy implementation. This paper tests five hypotheses that assess which factors influence the incarceration rate. The independent variables are overall minority population, public ideology, educational attainment, unemployment, and poverty. Each hypothesis predicts positive or negative relationships between the United States incarceration rate and the corresponding independent …


Judicial Conflicts And Voting Agreement: Evidence From Interruptions At Oral Argument, Tonja Jacobi, Kyle Rozema Jan 2018

Judicial Conflicts And Voting Agreement: Evidence From Interruptions At Oral Argument, Tonja Jacobi, Kyle Rozema

Faculty Articles

This Article asks whether observable conflicts between Supreme Court justices—interruptions between the justices during oral arguments—can predict breakdowns in voting outcomes that occur months later. To answer this question, we built a unique dataset based on the transcripts of Supreme Court oral arguments and justice votes in cases from 1960 to 2015. We find that on average a judicial pair is seven percent less likely to vote together in a case for each interruption that occurs between them in the oral argument for that case. While a conflict between the justices that leads to both interruptions and a breakdown in …


Diversity, Tenure, And Dissent, Joanna Shepherd Jan 2018

Diversity, Tenure, And Dissent, Joanna Shepherd

Faculty Articles

Although academics have long recognized that institutions such as opinion-assignment procedures and voting order might influence the propensity to dissent, empirical studies have failed to consider the impact of collegiality and personal relationships on dissent rates. Thus, in this short Essay, I empirically test whether some of the judges’ assertions are consistent with the data. I test whether various measures of diversity are associated with dissent rates in state supreme courts. I find that diversity in many areas—gender, race, age, religion, home state, and political affiliation—is associated with higher levels of dissent. In contrast, diversity in the jobs that judges …
