Classification Of Ad Tone In Political Video Advertisements Under Class Imbalance And Low Data Samples, Mohit Baskota Jan 2019

Classification Of Ad Tone In Political Video Advertisements Under Class Imbalance And Low Data Samples, Mohit Baskota

Creative Components

Ad tone defines the aim of a political video advertisement, which can be either to promote a specific candidate, to attack the candidates or to contrast the candidates. Depending upon the aim, a political video advertisement can be classified into either promote, attack or contrast class. Analysis of ad tone in political video advertisements can provide more insights about the political campaign to political science researchers. Political campaigns are investing more and more on online platforms, which creates a large amount of political video advertisements. Manual classification of ad tones in political video advertisement is time-consuming, labor intensive and not ...


Strategic Binary Choice Models With Partial Observability, Mark David Nieman Oct 2018

Strategic Binary Choice Models With Partial Observability, Mark David Nieman

Political Science Publications

Strategic interactions among rational, self-interested actors are commonly theorized in the behavioral, economic, and social sciences. The theorized strategic processes have traditionally been modeled with multi-stage structural estimators, which improve parameter estimates at one stage by using the information from other stages. Multi-stage approaches, however, impose rather strict demands on data availability: data must be available for the actions of each strategic actor at every stage of the interaction. Observational data are not always structured in a manner that is conducive to these approaches. Moreover, the theorized strategic process implies that these data are missing not at random. In this ...


Identifying Policy Agenda Sub-Topics In Political Tweets Based On Community Detection, Rohit Iyer, Johnny S. Wong, Wallapak Tavanapong, David A. M. Peterson Jan 2017

Identifying Policy Agenda Sub-Topics In Political Tweets Based On Community Detection, Rohit Iyer, Johnny S. Wong, Wallapak Tavanapong, David A. M. Peterson

Computer Science Conference Presentations, Posters and Proceedings

The explosive use of twitter in the political landscape presents new avenues for tracking political conversations at federal and state level. Tweets are used by state and federal government bodies to present citizens with information about future and present policies. It is also used by political candidates to express their views on policy changes, laws and to campaign for legislative body elections, the most recent example being the 2016 US presidential elections. In this paper, we use supervised learning, textual semantic similarity and community detection techniques to find actively discussed policy agenda sub-topics among political tweets within a certain time ...


Keeping Up With Which Joneses: Spatial Diffusion Of Rule Of Law Through Economic International Organizations, Olga Chyzh Jan 2016

Keeping Up With Which Joneses: Spatial Diffusion Of Rule Of Law Through Economic International Organizations, Olga Chyzh

Political Science Publications

I develop a theory of spatial diffusion of the rule of law, where “space” is conceptualized as shared memberships in economic international organizations (IOs). I argue that the rule of law diffuses as a result of economic competition and socialization. Outside evaluators, such as international leaders, activists, and most importantly, international firms and investors, often assess states’ attractiveness as a business venue by comparing them to similar states. The natural reference group for such comparisons is not just geographical neighbors, but also states with shared memberships in economic IOs. Responding to this evaluation, states identify members of their own reference ...


Dangerous Liaisons An Endogenous Model Of International Trade And Human Rights, Olga Chyzh Jan 2016

Dangerous Liaisons An Endogenous Model Of International Trade And Human Rights, Olga Chyzh

Political Science Publications

This article applies recent advances in network analysis to highlight a central tension faced by policymakers – balancing the benefits of engaging with the international system and the associated domestic policy costs. International trade rewards certain domestic practices, such as respect for human rights. Enforcing such practices, however, is politically costly and sometimes prohibitive to state leaders who rely on political repression to stay in power. In such cases, domestic elites often resort to an alternative strategy of securing the benefits of international trade – setting up indirect trade channels through intermediary states. These competing incentives are modeled within a single framework ...


Addressing Endogeneity In Actor-Speci Fi C Network Measures, Frederick J. Boehmke, Olga Chyzh, Cameron G. Thies Jan 2016

Addressing Endogeneity In Actor-Speci Fi C Network Measures, Frederick J. Boehmke, Olga Chyzh, Cameron G. Thies

Political Science Publications

The study of international relations (IR), and political science more broadly, has derived great benefits from the recent growth of conceptualizing and modeling political phenomena within their broader network contexts. More than just a novel approach to evaluating the old puzzles, network analysis provides a whole new way of theoretical thinking. Challenging the traditional dyad-driven approach to the study of IR, networks highlight actor interdependence that goes beyond dyads and emphasizes that many traditional IR variables, such as conflict, trade, alliances, or international organization memberships must be treated and studied as networks. Properties of these networks (e.g., polarization, density ...


The Spatial Dimensions Of State Fiscal Capacity The Mechanisms Of International Influence On Domestic Extractive Efforts, Cameron G. Thies, Olga Chyzh, Mark David Nieman Jan 2016

The Spatial Dimensions Of State Fiscal Capacity The Mechanisms Of International Influence On Domestic Extractive Efforts, Cameron G. Thies, Olga Chyzh, Mark David Nieman

Political Science Publications

This paper expands traditional predatory theory approaches to state fiscal capacity by adopting spatial analytical reasoning and methods. While previous work in the predatory theory tradition has often incorporated interdependent external influences, such as war and trade, it has often done so in a way that maintains a theoretical and empirical autonomy of the state. Theoretically, we suggest four mechanisms (coercion, competition, learning, and emulation) that operate to channel information through interstate rivalry and territorial contiguity, trade networks, and the political space associated with regime type and intergovernmental organization membership. We test our predictions using a multi-parametric spatio-temporal autoregressive model ...

Agenda Detector: Labeling Tweets With Political Policy Agenda, Sheetal Kaul Jan 2015

Agenda Detector: Labeling Tweets With Political Policy Agenda, Sheetal Kaul

Graduate Theses and Dissertations

In nearly one decade of Twitter’s being it has witnessed an ever growing user base from various realms of the world, one of them being politics. In the political domain, Twitter is used as a vital tool for communication purposes, running effective e-campaigns, and mining and affecting public opinions to name a few. We study the problem of automatically detecting whether a tweet posted by a state’s Senate’s twitter handle in the US has a reference to policy agenda(s). Such a capability can help detect the policy agendas that a state focuses on and also capture ...


On The Determinants Of Internal Armed Conflict, Nicholas James Hasty Jan 2015

On The Determinants Of Internal Armed Conflict, Nicholas James Hasty

Graduate Theses and Dissertations

This study expands upon literature on the cross-national causes of civil war and terrorism by combining the two concepts into an aggregate variable called internal armed conflict. It applies relative deprivation theory to politically excluded ethnic groups and also separates those two entities to examine socioeconomic desperation and ethnic exclusion respectively. From a review of the literature I identify eight variables that were found to be statistically significant predictors of either civil war or terrorism in previous studies and I use them as control variables in my models. I find that countries with excluded ethnic groups are somewhat more likely ...

College And University Dining Services Administrators’ Intention To Adopt Sustainable Practices: Results From Us Institutions, Chao-Jung (Rita) Chen, Mary Gregoire, Susan W. Arendt, Mack C. Shelley Jan 2011

College And University Dining Services Administrators’ Intention To Adopt Sustainable Practices: Results From Us Institutions, Chao-Jung (Rita) Chen, Mary Gregoire, Susan W. Arendt, Mack C. Shelley

Apparel, Events and Hospitality Management Publications

This study examined college and university dining services administrators’ (CUDSAs) intention to adopt sustainable practices. The theory of planned behavior (TPB) including constructs of subjective norm, attitude, perceived behavior control, and personal norm, formed the theoretical framework. A web-based questionnaire was developed, pretested, and distributed to 535 CUDSAs in the U.S.A. Results indicated that subjective norm (pressure from others) had the most influence on CUDSAs’ intention to adopt sustainable practices, followed by attitude and personal norm. Including the personal norm construct in the TPB model reduced unexplained variance by 33.48%. Limitations of this research are generalizability of ...

Four Dimensions Of Student Leadership: What Predicts Students' Attitudes Toward Leadership Developrnent?, John Shertzer, Vernon Wall, Alisa Frandsen, Yan Guo, Donald F. Whalen, Mack C. Shelley Ii

Political Science Publications

Multiple regression was performed on four dependent variables derived from the results of a student survey measuring attitudes about student leadership: (a) leadership is important to the student, (b) the student considers himself or herself to be a leader, (c) leadership will be important to the student after college, and (d) leaders need to be able to work in teams or groups. Each of 10 independent variables was a significant predictor of one or more dependent variables.


A Low Cost Virtual Reality Human Computer Interface For Cad Model Manipulation, Abhishek Seth, Shana Smith, Mack C. Shelley, Qi Jiang Jan 2005

A Low Cost Virtual Reality Human Computer Interface For Cad Model Manipulation, Abhishek Seth, Shana Smith, Mack C. Shelley, Qi Jiang

Political Science Publications

Interactions with high volume complex three-dimensional data using traditional two-dimensional computer interfaces have, historically, been inefficient and restrictive. However, during the past decade, virtual reality (VR) has presented a new paradigm for human-computer interaction. This paper presents a VR human-computer interface system, which aims at providing a solution to the human-computer interaction problems present in today’s computer-aided design (CAD) software applications. A data glove device is used as a 3D interface for CAD model manipulation in a virtual design space. To make the visualization more realistic, real-time active stereo vision is provided using LCD shutter glasses. To determine the ...


Emerging Bridges Over Contested Waters: Coalitions, Participatory Process, Social Capital And Community Capacity For Water Quality Protection , Stephen Philip Gasteyer Jan 2001

Emerging Bridges Over Contested Waters: Coalitions, Participatory Process, Social Capital And Community Capacity For Water Quality Protection , Stephen Philip Gasteyer

Retrospective Theses and Dissertations

Over the decade of the 1990s, there has been increasing attention to the factors that contribute to community organization for the protection of water quality. While much is theorized about the importance of education, leadership, and biophysical factors in this organization, few have laid out concrete models about the causal factors in creating community capacity for water quality protection. Building on research on social indicators, including indicators of community process, this research aims to demonstrate a clear relationship between attention to the social mobilization process and creation of community capacity to respond to water quality challenges. I use multivariate analysis ...


Party Formation And Policy Outcomes Under Different Electoral Systems, Massimo Morelli Aug 1998

Party Formation And Policy Outcomes Under Different Electoral Systems, Massimo Morelli

ISU Economic Report Series

This paper provides a game-theoretic model of representative democracy with endogenous party formation. Coalition formation may occur before and after elections, and the expected payoffs from the after-election majority game affect incentives-to form parties before the elections. In this way Duverger's hypothesis can be formally explained by the strategic behavior of political elites. If politicians care primarily about private benefits, the equilibrium policy outcome under a proportional electoralsystem coincides with the median party's position. On the other hand, with quasilinear utility, the.distance from the median voter outcome may be lower with plurality rule.


Assessment Of The United States Information Agency Sponsored University Affiliation Project Between Iowa State University And The National Agriculture University Of Ukraine Using The Concerns-Based Adoption Model (Cbam), Victor A. Udin Jan 1998

Assessment Of The United States Information Agency Sponsored University Affiliation Project Between Iowa State University And The National Agriculture University Of Ukraine Using The Concerns-Based Adoption Model (Cbam), Victor A. Udin

Retrospective Theses and Dissertations

The problem of this study was to evaluate the success of the Iowa State University (ISU) Linkage project (Crawford & Melnichuk, 1994) at the National Agricultural University of Ukraine (NAUU). The evaluation of the project's success and the educational changes it brought about were accomplished by determining the levels of use of the key elements of this change: the revised curriculum, new methods of teaching, and new teaching materials used at NAUU. This program evaluation research of the Linkage project was conducted based on the Concerns-Based Adoption Model (CBAM). The Levels of Use dimension of the Concerns-Based Adoption Model was applied to determine if the Linkage project was successful;The survey questionnaire consisted of sections describing the NAUU participants': demographic characteristics; knowledge of the English language; understanding of the essence of the Linkage project; awareness of the administrative changes at NAUU; and levels of use of the new curriculum developed as the result of the Linkage project. Statistical analysis revealed that neither demographic characteristics nor administrative reform has a relation to the levels of use of the main results of the Linkage project. The school environment was the only factor ...


A Spatial Econometric Model For Transboundary Air Pollution Control Treaties: An Analysis Of Noncooperative International Behavior , Keith Allen Sargent Jan 1997

A Spatial Econometric Model For Transboundary Air Pollution Control Treaties: An Analysis Of Noncooperative International Behavior , Keith Allen Sargent

Retrospective Theses and Dissertations

This dissertation develops a theoretical model that explains differences in emission reductions of transboundary air pollutants among nations based on national income, political freedom, the cost of emission reductions, emissions from other countries, the type of pollutant, and the pollutant's dispersion characteristics. The model is based on the theory of the private provision of impure public goods. This theoretical model is then used to derive a reduced form demand equation for emission reductions that can be econometrically estimated using spatial autoregressive techniques for time-series cross-section data;The econometric model is applied to 25 European nations and covers the period ...
