Determining Climate Responsibility: Government Liability For Hurricane Katrina?, Teresa Chan, Michael Burger, Vincent Colatriano, John Echeverria

Sabin Center for Climate Change Law

In St. Bernard Parish Government v. United States, Louisiana property owners argued that the U.S. government was liable under takings law for flood damage to their properties caused by Hurricane Katrina and other hurricanes. The U.S. Court of Appeals for the Federal Circuit disagreed, however, noting that the government cannot be liable on a takings theory for inaction, and that the government action was not shown to have been the cause of the flooding. On September 6, 2018, the Environmental Law Institute hosted an expert panel to explore this ruling and its potential implications for future litigation in a …

U.S. Climate Change Litigation In The Age Of Trump: Year Two, Dena P. Adler

Sabin Center for Climate Change Law

More than two and a half years into the Trump Administration, no climate change-related regulatory rollback brought before the courts has yet survived legal challenge. Nevertheless, climate change is one arena where the Trump Administration’s regulatory rollbacks have been both visible and real. The Administration has delayed and initiated the reversal of rules that reduce greenhouse gas (GHG) emissions from stationary and mobile sources; sought to expedite fossil fuel development, including in previously protected areas; delayed or reversed energy efficiency standards; undermined consideration of climate change in environmental review and other decisionmaking; and hindered adaptation to the impacts of climate …

Automated Deployment Of Cybersecurity Labs In Cloud Computing Environments, Christopher Simpson, Omar El-Gayar, Dave Bishop

Research & Publications

Government and private sector reports continue to highlight the shortage of qualified cybersecurity professionals. Hands-on cybersecurity labs can enhance student learning and augment the gap in qualified teachers. While there is a large body of research on cybersecurity labs, it is challenging to recreate these labs due to the use of proprietary software, significant hardware requirements, or large data transfer requirements. The automated deployment of IT infrastructure allows for the easy deployment and sharing of lab environments. This research proposes a framework for the use of DevOps tools to automate the deployment of cybersecurity labs that maps to specific learning …

A Socio-Technical-Based Process For Questionnaire Development In Requirements Elicitation Via Interviews, Abdullah Wahbeh, Surendra Sarnikar, Omar F. El-Gayar

Research & Publications

Software development is the process of building systems that solve users’ need and satisfy stakeholders’ objectives. Such needs are determined through requirements elicitation, which is considered an intensive, complex, and multi-disciplinary process. Traditional methods of elicitation often fail to uncover requirements that are critical for successful and wide-scale user adoption because these methods primarily focus on the technical aspects and constraints of the systems rather than considering a socio-technical perspective. The success of information system development involves the identification of the social, organizational and technical features of the systems, which in turn can result in a more acceptable system by …

Developing In Situ Dissolved Inorganic Carbon Dioxide Instrumentation, Beckett Colson

Link Foundation Ocean Engineering and Instrumentation Fellowship Reports

The ocean carbon system plays a critical role in regulating carbon dioxide content in the atmosphere. With increased anthropogenic carbon input, it is even more important to understand the system through measurements, models, and predictions. Unfortunately, the spatiotemporal resolution of ocean carbon system measurements is limited by a lack of in situ instrumentation. The support of the Link Foundation Ocean Engineering and Instrumentation Fellowship has enabled me to make significant progress in developing an in situ carbon system instrument for the deep sea. The instrument will measure both total dissolved inorganic carbon (DIC) and the partial pressure of carbon dioxide …

Antitrust In Digital Markets, John M. Newman

Articles

Antitrust law has largely failed to address the challenges posed by digital markets. At the turn of the millennium, the antitrust enterprise engaged in intense debate over whether antitrust doctrine, much of it developed during a bygone era of smokestack industries, could or should evolve to address digital markets. Eventually, a consensus emerged: although the basic doctrine is supple enough to apply to new technologies, courts and enforcers should adopt a defendant-friendly, hands-off approach.

But this pro-defendant position is deeply- and dangerously- flawed. Economic theory, empirical research, and extant judicial and regulatory authority all contradict the prevailing views regarding power, …

The Lived Experiences Of Adult Male Trauma Survivors With Dance Movement Therapy, Jeanne Langston

Walden Dissertations and Doctoral Studies

In the United States, approximately 7.7 million individuals are affected by posttraumatic stress disorder (PTSD) at any given time. Though women are likelier to develop PTSD symptoms, men are exposed to more traumatic events in their lifetimes. Empirically- supported PTSD options exist, however clinical application of these treatments may not consistently culminate in beneficial outcomes. Dance Movement Therapy (DMT) has demonstrated positive treatment outcomes for a variety of mental and physical disorders. Nonetheless, there is a lack of robust research related to the treatment experiences of men who have participated in DMT for trauma-related symptoms. The purpose of this phenomenological …
