The Boundaries Of Multi-Parentage, Jessica Feinberg

SMU Law Review

Multi-parentage has arrived. In recent years, a growing number of courts and legislatures have recognized that a child may have more than two legal parents. A number of significant societal, medical, and legal developments have contributed to the trend toward multi-parentage recognition. The traditional family structure of a married different-sex couple and their biological children currently represents only a minority of U.S. families. Stepparents, non-marital partners of legal parents, and extended family members often play a significant role in children’s lives, and it has become increasingly common for same-sex couples to welcome children into their families. In addition, advancements in …

Algorithmic Destruction, Tiffany C. Li

SMU Law Review

Contemporary privacy law does not go far enough to protect our privacy interests, particularly where artificial intelligence and machine learning are concerned. While many have written on problems of algorithmic bias and data deletion, this Article introduces the novel concept of the “algorithmic shadow” and explains the new privacy remedy of “algorithmic destruction,” also known as algorithmic disgorgement or machine unlearning. The algorithmic shadow describes the persistent imprint of training data that has been fed into a machine learning model and used to refine that machine learning system. This shadow persists even if data is deleted from the initial training …

The Discovery And Investigation Of Jig (Cg14850): A Previously Uncharacterized Novel Drosophila Melanogaster Protein, Sayem Hoque Bhuiyan

Theses and Dissertations

Despite Drosophila being one of the most studied model organisms in the world of research, one-third of 14,000 protein-encoding genes that the Drosophila genome possesses code for proteins that are yet uncharacterized. While investigating some of these uncharacterized Drosophila proteins, we identified a scarce protein type–a protein localized in both mitochondria and nucleus. Proteins, dual-localized in mitochondria and nucleus, establish communication between these organelles. This type of dual-localized protein is among the rarest of proteins, which limits us from fully understanding the mito-nuclear communication mechanism. Here, we tell the story of Jig, which we discovered to be one of those …

P&I Club Membership As Potential Incentivization For Adherence To Best Space Traffic Management Practices: A Maritime Analogue, Cristin M. Finnigan

Theses and Dissertations

It has been said that the space environment is becoming so accessible, we are at risk of depleting it as a resource, thereby risking society’s space-dependent functions. Law, regulations, policies, and guidelines exist to guide entities to act to preserve the space environment. However, best space traffic management (STM) practice implementation and regulatory compliance could be costly and resource-intensive, especially for a small business. Some entities may not undertake innovative space endeavors at all, or worse, ignore laws, regulations, policies, and guidelines. A question arises of how space actors could be persuaded to work toward meeting STM laws, regulations, policies, …

The Architecture And Dynamics Of Gene Regulatory Networks Directing Cell-Fate Choice During Murine Hematopoiesis, Joanna Handzlik

Theses and Dissertations

Mammals produce hundreds of billions of new blood cells every day througha process known as hematopoiesis. Hematopoiesis starts with stem cells that develop into all the different types of cells found in blood by changing their genome-wide gene expression. The remodeling of genome-wide gene expression can be primarily attributed to a special class of proteins called transcription factors (TFs) that can activate or repress other genes, including genes encoding TFs. TFs and their targets therefore form recurrent networks called gene regulatory networks (GRNs). GRNs are crucial during physiological developmental processes, such as hematopoiesis, while abnormalities in the regulatory interactions of …

An Examination Of The Effects Of Body Mapping Instruction On Singers’ Static Standing Posture And Posture While Singing, Amanda Moreno

Theses and Dissertations

Physical posture is one of the fundamental aspects of vocal technique, and voice pedagogues suggest that effective alignment is necessary for healthy vocal production. Body Mapping (BMG) is a somatic method that focuses on the understanding and correction of errors in a person’s body map to facilitate effective movement for musical activity. Because this method has balance, physical alignment, and posture as foundational, it may be an effective way to begin to instruct students. This study investigated whether the use of the BMG method, which teaches posture through movement, scientific pictures, and anatomical models, would result in a significant difference …

Behavioral Responses Of Breeding Ducks To Unmanned Aerial Vehicle Surveys And Best Practices For Breeding Waterfowl Surveys Using Unmanned Aerial Vehicles, Mason Ryckman

Theses and Dissertations

Unmanned aerial vehicles (UAVs) have become a popular wildlife survey tool. As such, biologists are exploring the use of UAVs for surveying waterfowl. The most cited benefit of using UAVs over traditional methods is the idea of reduced disturbance, but this has had limited formal evaluation across species. We conducted UAV surveys with associated behavioral observations of ducks on wetlands and on nests during the 2019 – 2020 breeding seasons. We found species-specific behaviors among blue-winged teal (Spatula discors), northern shoveler (Spatula clypeata), and gadwall (Mareca strepera) including ducks noticing the aircraft, but reactions were generally less than traditional ground …

Phylogenetic Relationships Of Noctuoid Moths With An Examination Of Complex Characteristics, Melissa Sisson

Theses and Dissertations

The tribe Noctuini comprise over 520 species; many are economically important species that impact human agriculture. Despite their diversity and relevance, relationships of the Noctuini have been difficult to resolve. There are extensive morphological revisions of these taxa (e.g., Agrotis, Euxoa); however, there are no studies that focus exclusively on the phylogenetic relationships of the Noctuini. Currently, the Noctuini are separated into two subtribes, the Agrotina and Noctuina, which each are further subdivided into two subgenera. In this study, we tested previous classification schemes using three loci. We sampled three outgroup taxa and 54 noctuine species that represent the majority …

Fourth Amendment Privacy In Public: A Fundamental Theory With Application To Location Tracking, Jordan Wallace-Wolf

Law Faculty Scholarship

When we walk out our front door, we are in public and other people may look at us. But intuitively, we don’t open ourselves up to unlimited scrutiny just by going outside. We retain some privacy, even in public. What is the source of this residual public-privacy, and how should the law recognize it without degrading the open character of public space?

The answer given by commentators, and most recently by the Supreme Court in Carpenter v. U.S., comes in the form of two related claims. The first is the chilling theory of the Fourth Amendment. According to this idea, …
