Revisiting Patent Linkage, John R. Thomas

Georgetown Law Faculty Publications and Other Works

Alfred Engelberg’s article of a quarter-century ago, Special Patent Provisions for Pharmaceuticals: Have They Outlived Their Usefulness?, raised a provocative question that retains currency today. The special provisions that Hatch-Waxman established, and Engelberg addressed, have come to be known as patent linkage. Following the principle of linkage, the Food and Drug Administration (FDA) cannot approve generic drugs for marketing if they would infringe a patent.

Hatch-Waxman’s complex patent provisions aspire towards multiple salutary purposes, including encouraging the prompt availability of generic drugs, improving public notice of pharmaceutical patents, and accelerating dispute resolution proceedings. Congress also attempted to ameliorate perceived …

The Fiduciary Code Of Capital And Climate Change, Seth Davis, Gregory Shaffer

Georgetown Law Faculty Publications and Other Works

Fiduciary law is part of the “code” for the management of capital, as Katharina Pistor has conceptualized law. Climate activists, attorneys, investors, and international organisations have turned to fiduciary law for legal solutions to the ongoing problem of inadequate corporate and state action in response to climate change. Our thesis is that the turn to fiduciary law by norm entrepreneurs is an attempt to encode a concern for climate change within the management of capital. We make two contributions to the literature on private law and climate change. First, we rigorously identify the features of fiduciary law that make it …

As the regulatory landscape for the Internet of Things (IoT) evolves, vendors are moving towards certifying their products for security. Thus, we need to understand who is liable when certification failures result in harm, i.e., when certified products have vulnerabilities that are exploited to cause harm to users. This paper addresses the fundamental and timely question that has significant implications for vulnerability detection in certified products: who is liable for harm resulting from vulnerabilities in certified products, and who should be so liable? Through a qualitative analysis of contractual documents from 20 IoT vendors, this paper investigates how liability is …

Weathering And Beyond: Leveraging Mathematical Modeling To Simulate Erosion In Digital Media, Fiona Irving-Beck

Scripps Senior Theses

How might we bring an idea to life from both a mathematical and an artistic perspective? Within Weathering, I use imagery of environmental erosion to explore the differences between physical and digital forms of representation. I created a physical painting of an abandoned copper mine, digitized the work, and then used a mathematical model to digitally “erode” it, which I re-translated into paintings. While the explicit texture present in physical work speaks best to my practice/intent, the mathematical framework that is the basis for my digital work affords a powerful mode of temporal flexibility. Used in conjunction, these two …

“Ignorance Is No Excuse”: Reproducing The Normative Female Body Through Mass Consumerism In Post-Wwii Women’S Magazines, Hannah E. Lorenz-Meyer

Scripps Senior Theses

In the Post-War era, women’s magazines took on a key role in cultural production, publishing literature, non-fiction articles, and advice on everything from marriage to fashion. Women’s magazines served a a form of propaganda, promoting a specific form of femininity that upheld the status quo. And that form of femininity was overwhelmingly affluent and White. By establishing magazines as a solution to women’s personal problems, editors served to shape the image of the post-war American woman. Nowhere is this vision more intimate than the way it was applied to the female body and reproduction. In this thesis, I analyze how …

Representing Childhood: Abstraction And Aesthetics Of Simplicity In Ezra Jack Keats's The Snowy Day, Elle Propp

The P3 Event-Related Potential (Erp) In Visual And Auditory Tasks: Implications For Executive Functioning In Adhd Preadolescent Children, Alex Visal Seng

Open Access Master's Theses

Attention-Deficit/Hyperactivity Disorder (ADHD) is a widespread psychological disorder in children, poorly impacting executive functioning domains of inhibitory control and working memory. Event-related potentials (ERPs) provide neuroelectric insight into these cognitive processes. However, most ERP research focuses on one task type, limiting direct comparisons of cognitive demands across different task paradigms. This study examined P3 amplitude and latency in ADHD children using a visual NoGo task (response inhibition) and an auditory oddball task (working memory), and associations between the P3 ERP and behavioral measures of executive functions.

Cross-sectional data of symptomatic ADHD children (N=13; F=5; aged 9.15 ± 1.86 years) were …
