Faculty Publications

Early detection of a gas kick is crucial for preventing uncontrolled blowout that could cause loss of life, loss of assets, and environmental damage. Multiphase flow experiments conducted in this research demonstrate the capability of downhole fiber optic sensors to detect a potential gas influx in real-time in a 5000 ft deep wellbore. Gas rise velocities estimated independently using fiber optic distributed acoustic sensor (DAS), distributed temperature sensor (DTS), downhole gauges, surface measurements, and multiphase flow correlations show good agreement in each case, demonstrating reliability in the assessment. Real-time data visualization was implemented on a secure cloud-based platform to improve …

Weaving Strands Of Knowledge: Leaning About Environmental Change In The Bhutan Himalayas, Sameer Honwad, Andrew D. Coppens, Greg Defrancis, Marcos Stafne Montshire, Shivaraj Bhattarai

Faculty Publications

Climate change is a complex phenomenon, so much so that even those with expert knowledge on the scientific data struggle to understand the impacts of climate change on their everyday lives. Contradictions across systems of knowledge make clear that climate change is not just a problem of scientific understanding but is also simultaneously a problem of global coordination as well as a sociopolitical problem of connecting domains of knowledge that are seldom valued equitably. The project described in this paper is a prototype effort to put knowledge from community members in two culturally distinct rural areas of the world at …

Agnew, Abc, And Richard Nixon's War On Television, Dale L. Cressman Phd

Faculty Publications

Less than a year into the presidency of Richard Nixon, Vice President Spiro Agnew launched a series of attacks on television journalists, accusing them of being biased and having too much power to determine what news millions of Americans watched on their televisions. Because the government licensed and regulated their stations, the networks considered Agnew's statements, and other White House criticisms, to be threats. As the smallest, most vulnerable network, ABC found itself at a confluence of relationships with the administration: It employed both Nixon's favorite and least favorite anchors, as well as a highly placed executive who lent sympathy …

From Community Policing To Political Police In Nicaragua, Lucia Dammert, Mary Fran T. Malone

Faculty Publications

In a region plagued by high rates of violent crime and repressive policing practices, Nicaragua has earned a reputation as exceptional. Despite poverty, inequality, and a historical legacy of political violence and repression, Nicaragua has defied regional trends. It has registered low rates of violent crime while deploying policing practices that emphasized prevention over repression. April 2018 marked an end to this exceptionalism. Police attacked anti-government protestors, and launched a sustained campaign against dissidents that continues to the present day. While the Nicaraguan police had long cultivated a reputation as community-oriented and non-repressive, they appeared to quickly change into a …

A Magma Ocean Origin To Divergent Redox Evolutions Of Rocky Planetary Bodies And Early Atmospheres, Jie Deng, Zhixue Du, Bijaya B. Karki, Dipta B. Ghosh, Kanani K.M. Lee

Faculty Publications

Magma oceans were once ubiquitous in the early solar system, setting up the initial conditions for different evolutionary paths of planetary bodies. In particular, the redox conditions of magma oceans may have profound influence on the redox state of subsequently formed mantles and the overlying atmospheres. The relevant redox buffering reactions, however, remain poorly constrained. Using first-principles simulations combined with thermodynamic modeling, we show that magma oceans of Earth, Mars, and the Moon are likely characterized with a vertical gradient in oxygen fugacity with deeper magma oceans invoking more oxidizing surface conditions. This redox zonation may be the major cause …

Eager To Follow: Methodological Precedent In Statutory Interpretation, Aaron-Andrew P. Bruhl

Faculty Publications

An important recent development in the field of statutory interpretation is the emergence of a movement calling for "methodological precedent"--a regime under which courts give precedential effect to interpretive methodology. In such a system, a case would establish not only what a particular statute means but could also establish binding rules of methodology--which tools are valid, in what order, and so on. The movement for methodological precedent has attracted sharp criticism on normative grounds. But both sides of the normative debate agree on the premise that the federal courts generally do not give precedential effect to interpretive methodology today.
