The Evolution Of Norms And Their Influence On Performance Among Self-Governing Irrigation Systems In The Southwestern United States, Kelsey C. Cody Apr 2019

The Evolution Of Norms And Their Influence On Performance Among Self-Governing Irrigation Systems In The Southwestern United States, Kelsey C. Cody

Environmental Studies Graduate Contributions

Irrigation is important for global food supply and is vulnerable to cli- mate change. Internalized cultural norms are important for the performance of Common Pool Resource (CPR) regimes such as irrigation systems, but much is unknown about the role of norms in shaping irrigation performance. This paper applies multi-level selection (MLS) theory and CPR theory to a stratified, semi- random sample of 71 irrigation systems of distinct cultural origins in the Upper Rio Grande Basin of the United States to test hypotheses related to the role of norms in irrigation system form and function. Results show that internalized norms of ...


Search For A Heavy Resonance Decaying To A Pair Of Higgs Bosons In The Four B-Quark Final State With The Cms Experiment, Michael D. Krohn Jan 2018

Search For A Heavy Resonance Decaying To A Pair Of Higgs Bosons In The Four B-Quark Final State With The Cms Experiment, Michael D. Krohn

Physics Graduate Theses & Dissertations

A search for a massive resonance decaying into a pair of standard model Higgs bosons, in a final state consisting of two b quark-antiquark pairs, is performed using proton-proton collisions at a center-of-mass energy of 13 TeV collected by the Compact Muon Solenoid detector at the Large Hadron Collider and corresponding to an integrated luminosity of 35.9 fb-1. The Higgs bosons are highly Lorentz-boosted and are each reconstructed as a single large-area jet. The signal is characterized by a peak in the dijet invariant mass distribution, above a background from the standard model multijet production. The observations are ...


Sum Over Histories Representation Of Chemical Kinetics: An Interpretive And Predictive Method For Modeling Chemical Kinetics Using Time-Dependent Pathways, Shirong Bai Jan 2018

Sum Over Histories Representation Of Chemical Kinetics: An Interpretive And Predictive Method For Modeling Chemical Kinetics Using Time-Dependent Pathways, Shirong Bai

Chemistry & Biochemistry Graduate Theses & Dissertations (1986-2018)

Chemical kinetics can be viewed as an intricate network of inter-related chemical reactions that work cooperatively to convert reagent species into product species. The network is in general time dependent reacting the non-steady state nature of the chemistry. When it comes to interpreting and predicting chemical kinetics, the history of chemical moieties can play vital roles. In order to study the histories of chemical substances using time-dependent chemical network, this thesis focuses on developing a Sum Over Histories Representation (SOHR for short) of chemical kinetics.

The description of time-dependent chemistry of a reaction network is provided by chemical pathways defined ...


Low-Rank, Multi-Fidelity Methods For Uncertainty Quantification Of High-Dimensional Systems, Hillary Ruth Fairbanks Jan 2018

Low-Rank, Multi-Fidelity Methods For Uncertainty Quantification Of High-Dimensional Systems, Hillary Ruth Fairbanks

Applied Mathematics Graduate Theses & Dissertations

Characterizing and incorporating uncertainties when simulating physical phenomena is essential for improving model-based predictions. These uncertainties may stem from a lack of knowledge regarding the underlying physical processes or from imprecise measurements of quantities that describe properties of the physical system. Uncertainty quantification (UQ) is a tool that seeks to characterize the impact of these uncertainties on solutions of computational models, resulting in improved predictive models. In practice, these uncertainties are either treated as random parameters to inform the statistics of the solution of interest (forward UQ), or their statistics are inferred from noisy observations of the solutions (inverse UQ ...


A National Security Threat: Washington's Conflicting Response To Climate Change In Northern Pakistan, Katherine Henjum Jan 2017

A National Security Threat: Washington's Conflicting Response To Climate Change In Northern Pakistan, Katherine Henjum

Undergraduate Honors Theses

Developing countries such as Pakistan are particularly susceptible to the negative implications of changing climates as they face regional and in-country terrorism and violence, as well as infrastructure and government institutions that are still evolving. This thesis examines the intersection of climate change and national security through an analysis of shifting monsoon patterns and the subsequent impacts on vulnerable and displaced populations in northern Pakistan.

Over the past decade, the United States has chosen to act through two primary foreign policy methods: a military oriented approach focused on drone strikes and a humanitarian approach focused on foreign aid and development ...


Scientific Authority: An Epistemic Proceduralist Framework For The Legitimate Authority Of Science In Environmental Policy, Matthew Evan Heller Jan 2015

Scientific Authority: An Epistemic Proceduralist Framework For The Legitimate Authority Of Science In Environmental Policy, Matthew Evan Heller

Political Science Graduate Theses & Dissertations

The formation and implementation of effective environmental policies by Western liberal democracies are frequently hindered by disagreement over the appropriate role of scientific knowledge. In my dissertation, I argue this obstruction is resolved by recognizing the legitimate authority of science in environmental policy-making. Drawing on David Estlund’s epistemic proceduralist theory of democracy, I demonstrate the compatibility of the authority of scientific knowledge claims about the cause and effect relationships of the biophysical world in environmental policy-making with our normative expectations for the justifications of democratic governance. After defending this approach to understanding the science-policy interface, I demonstrate the feasibility ...
