Computational Approaches To Study Post Transcriptional Regulation Events, Naima Ahmed Fahmi

Graduate Thesis and Dissertation post-2024

A simplistic understanding of the central dogma falls short in correlating the number of genes in the genome to the number of proteins in the proteome. Post-transcriptional regulation, including alternative splicing and alternative polyadenylation contribute to the complexity of the proteome and is critical in understanding gene expression. In this dissertation, we aim to provide genome-wide detection and visualization of the transcript variants and quantify their significance in gene regulation. First, we propose a robust computational program to identify alternative splicing events from RNA-seq data, called AS-Quant. Our extensive experiments on simulated and real datasets demonstrate that AS-Quant can accurately …

Thermal Analysis Of Additively Manufactured Aluminum F357 And Inconel 718 In High-Enthalpy Hypersonic Flows, Andrew La Sorsa

Graduate Thesis and Dissertation post-2024

Hypersonic vehicles are not only limited by the propulsion systems needed to achieve such speeds but also by the conventional materials currently at hand. At speeds of Mach 5 and above, sections of the vehicle can experience local temperatures exceeding 3000 K, which can severely degrade any material not rated to withstand such extreme environments. This warrants the need for developing novel high-temperature resistant materials to be safely integrated into hypersonic vehicles. Additive manufacturing has been identified as a solution to the process of creating these materials and offers increased design flexibility and quality compared to conventional fabrication methods. A …

Comparison Of Bearing Capacity Estimates To The Barcelona Basic Model Implemented Through Finite Element Modeling In Plaxis2d, Carlee M. Shaw

Graduate Thesis and Dissertation post-2024

The design of foundations is greatly influenced by its bearing capacity and settlement behavior, especially for that of shallow foundations which lie within the unsaturated zone of soil. Similarly, bearing capacity of beach sands can be utilized to determine beach trafficability, as vehicular loads may be assumed within the unsaturated zone. Therefore, similar scenarios should be analyzed as partially saturated conditions, unlike conventional bearing capacity estimations. To analyze such conditions, the concept of soil suction has more recently been of consideration. In this paper, the load-settlement behavior of a sand in partially saturated conditions is explored through finite element modelling …

Evaluating Sexual Dimorphism In Occipital Morphological Shape Through Modern Human Ontogenetic Changes, Jennifer S. Barritt

Graduate Thesis and Dissertation post-2024

Sex estimation is vital to building the biological profile in forensic anthropology. Cranial nonmetric traits are often used in adult sex estimation due to their sexually dimorphic nature. However, only one nonmetric trait is assessed on the occipital despite the bone’s postmortem durability. While these sex estimation methods were developed for use on adult crania, juvenile sex estimation is less accurate due to differences in the age at which individuals reach sexual maturity. The aim of this study was to improve upon existing sex estimation methods by accounting for shape differences that exist within the occipital. This study used computed …

Meaningful Or Meaningless? The Temporal Scope Of The Constitutional Right Of Access To Courts For Incarcerated Litigants, Alison Aimers

Cardozo Law Review de•novo

This Note will advocate for the position taken by the Third and Seventh Circuits that incarcerated individuals’ right to affirmative assistance in accessing legal materials extends past the pleading stage to all stages of civil rights claims and post-conviction criminal appeals. U.S. Supreme Court precedent supports this position, and judicial clarity on this issue is required to best protect the constitutional right of access in light of significant existing barriers to incarcerated litigants’ access to courts.

Corn War: A Trade Fight Between The United States And Mexico, Ernesto Hernández-López

Cardozo Law Review de•novo

An international fight grows over corn. The United States claims that México’s ban on genetically modified (GMO) corn violates the United StatesMexico-Canada Agreement (USMCA). México prohibits GMO corn for human consumption. American arguments focus on Sanitary and Phytosanitary (SPS) measures, covered in Chapter 9 of the USMCA. A trade panel will review these.

This Essay first describes SPS arguments and relevant trade rules. The United States’ complaints emphasize that México’s ban is excessive, is not consistent with international standards, and mishandles risks. Second, the Essay identifies the obstacles American positions face: weak mandates and deference to México. Chapter 9 of …

Expanding Homicide Liability For A Parent’S Omission, Monu Bedi

Cardozo Law Review de•novo

Earlier this year, Jennifer and James Crumbley were convicted of manslaughter and sentenced to 10-15 years for not stopping their teenage son, Ethan, from killing four students at his high school. This is the first known occurrence of an American prosecutor obtaining a homicide conviction relying on a parental omission—or failure to act—where the victim was not the parent’s own child. Parental omissions historically have only triggered homicide charges if the parent fails to protect their child, not others, from harm. Unlike the general population, parents owe a special duty to their child because they are the ones tasked to …

Graduate Thesis and Dissertation post-2024

This thesis investigates the relationship between politics, law, race, mobility, and violence in 1890s Illinois to highlight the socio-political causes of a temporary pro-labor shift in Republican policy. It centers on Illinois Governor John R. Tanner’s atypical response to racialized labor violence during the Virden Affair and the broader Coal Wars of 1898-1899. This research builds on socio-economic and cultural studies of the labor movement and Black strikebreaking. It introduces state politics and law, two essential lenses of analysis which the historiography has largely neglected in favor of economics and bottom-up history. In lieu of the typical pro-labor accounts of …

The End Of Consent: Data And The Corporate-Consumer Relationship, Faisal Hijjawi

LL.M. Essays & Theses

Consumer data is largely regulated through the notice-and-choice approach in the United States, which relies on consumer consent. The notice-and-choice approach is rooted in the control theory of information privacy. This paper will argue that the control theory is limited due to its reliance on property law, its breadth, as well as it reinforcing the ‘no privacy in public’ concept. Further, the notice-and-choice approach relies on consent being both free and informed. However, consent cannot be considered free due to the lack of choice and the manipulation exerted on the consumer. Also, consent is not informed as the consumer lacks …

Fair Use V. Free Use: A Comparative Study Of American And Russian Copyright Exemptions, Eduard Bershitskiy

LL.M. Essays & Theses

Many U.S. lawyers are under the well-deserved, but still not entirely accurate, impression that copyright infringement in Russia is a huge free-for-all. This comparative paper, which juxtaposes Russian and American copyright exemptions, seeks to partially refute that skeptic view by showing that, in fact, Russian copyright law has developed a relatively coherent system of exceptions and limitations to exclusive rights. This paper begins with a brief overview of Russian copyright law and general remarks on its exemptions. It then focuses on statutory and, where appropriate, case-law comparison of particular copyright exemptions in the Part 4 of the Russian Civil Code …

Can Community Festivals Make Urban Places More Hospitable?, Bernadette Quinn

Articles

Cultivating places and spaces to encourage sociality and foster sociocultural inclusion is a very pertinent societal challenge. Community festivals are often marshalled in the interest of making cities more hospitable for the increasing numbers of migrants, refugees, remote workers and tourists internationally on the move. This study investigates if and how community festivals are constructing hospitality through their practices. The findings are drawn from a qualitative study of two community festivals in Dublin's North East Inner City, an ethnically diverse area characterized by social disadvantage. They suggest that community festivals can make places more hospitable. However, the approaches taken to …

Social Problem-Solving, Stress, Social Support As Predictors Of Distress Among First-Generation Students, Marisa Leib

PCOM Psychology Dissertations

First-generation students are steadily increasing in the United States, and currently comprise one third of today’s college undergraduate population (Stebleton & Jehangir, 2020). First-generation students are more likely to face various academic, social, economic, and cultural challenges when transitioning to higher education. The culmination of these stressors put first-generation students at risk for developing mental health conditions. Social problem-solving (SPS) is one variable that has been shown to buffer against the negative effects of stress among the general college student population. The purpose of the current study was to examine how specific variables contribute to psychological distress among the population …
