Time To Heal: Trauma's Impact On Rape & Sexual Assault Statutes Of Limitations, Fredrick E. Vars, Jillian Miller Purdue Jan 2023

Time To Heal: Trauma's Impact On Rape & Sexual Assault Statutes Of Limitations, Fredrick E. Vars, Jillian Miller Purdue

Articles

Short statutes of limitations for sex crimes ask the impossible of many vic- tims: report the crime before they have recovered from the trauma. Perpetra- tors go free as a direct result of the injury they caused. Nearly a third of victims of rape and sexual assaulthave PTSD during their lifetimes. PTSD is associated with three symptoms pertinent to reporting a crime: avoidance cop- ing (avoidingdistressing thoughts, feelings, or reminders of the attack), disso- ciative amnesia (forgetting important or all aspects of the attack), and depression. These symptoms all affect a victim's psychological ability to report a crime before a …


Defamation With Bayesian Audiences, Yonathan A. Arbel, Murat C. Mungan Jan 2023

Defamation With Bayesian Audiences, Yonathan A. Arbel, Murat C. Mungan

Articles

How strictly should the law regulate false defamatory statements? We first show that the presence of judicial errors often puts defamation law on a Laffer curve: regulation that is too lax or too strict is inferior to moderate regulation. While moderate regulation is ideal, it is not always attainable because of practical and legal constraints. With these constraints, we consider a Bayesian audience that takes the strictness of defamation law into account when evaluating statements. The optimal standard is then taxer than is prescribed by standard models with naive audiences. These findings underscore the importance of accounting for audience effects …


The Credibility Effect: Defamation Law And Audiences, Yonathan A. Arbel Jan 2023

The Credibility Effect: Defamation Law And Audiences, Yonathan A. Arbel

Articles

What should be the legal response to false statements? In the context of defamation law, courts try to set a standard that balances the interests of speakers and their potential targets. This article empirically demonstrates an unappreciated effect of such decisions on third parties: a credibility effect. Using a series of lab experiments, I find that defamation law makes individuals more trusting of reports from various media. This credibility effect is desirable when the report is true but can lead to unintended consequences in the case of misinformation. In particular, the credibility effect is shown to cast a stigma on …


Crying Wolf: Neo-Patriots, Critical Race Theory, And The Constitutional Protection Of "Dangerous" Ideas, Bryan K. Fair Jan 2023

Crying Wolf: Neo-Patriots, Critical Race Theory, And The Constitutional Protection Of "Dangerous" Ideas, Bryan K. Fair

Articles

Most Americans do not realize that, notwithstanding the First Amendment's free speech guarantee, for most of our nation's history, judges sent men and women to prison for expressing ideas considered too "dangerous." It was not until the late 1960s that the Supreme Court rejected the clear and present danger doctrine, insisting that statutes banning speech must draw a distinction between advocacy of ideas and advocacy of imminent lawless action. The Court held that under that constitutional norm, the government could not send a Klansman to prison for expressing racist, anti-Semitic, or otherwise dangerous or offensive ideas. Since then, banning the …


Noncitizen Harboring And The Freedom Of Association, Shalini Bhargava Ray Jan 2023

Noncitizen Harboring And The Freedom Of Association, Shalini Bhargava Ray

Articles

The United States has long criminalized assistance to unauthorized migrants. It is a crime to smuggle, transport, harbor, or encourage unauthorized migrants to remain in the country, regardless of the reasons for such aid. In response to recent federal harboring prosecutions of humanitarians assisting migrants at the U.S.- Mexico border, scholars and advocates have shown tremendous interest in a defense to liability under the Religious Freedom Restoration Act and the First Amendment's Free Speech Clause. But a comparative analysis of harboring law reveals that some foreign jurisdictions conceptualize harboring law and defenses to liability in terms of citizen-migrant associations rather …


The Public Voice Of The Defender, Russell M. Gold, Kay L. Levine Jan 2023

The Public Voice Of The Defender, Russell M. Gold, Kay L. Levine

Articles

For decades police and prosecutors have controlled the public narrative about criminal law. The news landscape features salacious stories of violent crimes while ignoring the more mundane but far more prevalent minor cases that clog the court dockets. Defenders, faced with overwhelming caseloads and fear that speaking out may harm their clients, have largely ceded the opportunity to offer a counternarrative based on what they see every day. Defenders tell each other about the overuse of pretrial detention, intensive pressure to plead guilty, overzealous prosecutors, cycles of violence, and rampant constitutional violations-all of which inflict severe harm on defendants and …


From Cannabis To Crypto: Federal Reserve Discretion In Payments, Julie Andersen Hill Jan 2023

From Cannabis To Crypto: Federal Reserve Discretion In Payments, Julie Andersen Hill

Articles

From its inception, the Federal Reserve has operated payment systems that let banks move money for their customers. Checks, wire transfers, and electronic consumer payments all happen thanks to the Federal Reserve. Congress by statute specified which banks get access to the Fed's payment services. For more than a century, the Federal Reserve provided services to all legally eligible banks. But when the Federal Reserve received requests for payments access from a cannabis-focused credit union and a cryptocurrency custody bank (both of whom are legally eligible), it denied them. The Fed also issued sweeping guidelines claiming discretion to conduct risk …


Opening A Federal Reserve Account, Julie Andersen Hill Jan 2023

Opening A Federal Reserve Account, Julie Andersen Hill

Articles

To open bank accounts, new customers provide personal information and make a deposit. Within a few minutes (or perhaps a few days), new customers get access to payment services. For many years, the process financial institutions used to open accounts at FederalReserve Banks was similar. Eligible banks filled out a one-page form and within a week received an account allowing them access to the FederalReserve's payment systems. Recently, however, Federal Reserve Banks have spent years considering account requests from novel banks.

This Article examines the Federal Reserve's process for evaluating requests for accounts. Using interviews, court documents, and other sources, …


At The Nexus Of Antitrust & Consumer Protection, Luke Herrine Jan 2023

At The Nexus Of Antitrust & Consumer Protection, Luke Herrine

Articles

This Essay uses Section 5 of the Federal Trade Commission Act to examine the theoretical and practical relationship between antitrust and consumer protection law. It argues that, since roughly 1980, there has been a hegemonic "neoliberal"framework, one that has in recent years been challenged by an emerging "moral economy" framework. The neoliberal framework conceptualizes antitrust as preventing firms from conspiring to throttle output, with a focus primarily on consumers' interests in low prices, and consumer protection as making consumers informed, rational, and able to switch between competitors with relatively low cost. The moral economy framework conceptualizes both areas of law …

Cloud-Native Distributed Genomic Pileup Operations, Marek Wiewiórka, Agnieszka Szmurło, Paweł Stankiewicz, Tomasz Gambin Jan 2023

Cloud-Native Distributed Genomic Pileup Operations, Marek Wiewiórka, Agnieszka Szmurło, Paweł Stankiewicz, Tomasz Gambin

Faculty, Staff and Students Publications

MOTIVATION: Pileup analysis is a building block of many bioinformatics pipelines, including variant calling and genotyping. This step tends to become a bottleneck of the entire assay since the straightforward pileup implementations involve processing of all base calls from all alignments sequentially. On the other hand, a distributed version of the algorithm faces the intrinsic challenge of splitting reads-oriented file formats into self-contained partitions to avoid costly data exchange between computational nodes.

RESULTS: Here, we present a scalable, distributed and efficient implementation of a pileup algorithm that is suitable for deploying in cloud computing environments. In particular, we implemented: (i) …


Alveolar Macrophages In Lung Cancer: Opportunities Challenges, Cheng-Yen Chang, Dominique Armstrong, David B Corry, Farrah Kheradmand Jan 2023

Alveolar Macrophages In Lung Cancer: Opportunities Challenges, Cheng-Yen Chang, Dominique Armstrong, David B Corry, Farrah Kheradmand

Faculty, Staff and Students Publications

Alveolar macrophages (AMs) are critical components of the innate defense mechanism in the lung. Nestled tightly within the alveoli, AMs, derived from the yolk-sac or bone marrow, can phagocytose foreign particles, defend the host against pathogens, recycle surfactant, and promptly respond to inhaled noxious stimuli. The behavior of AMs is tightly dependent on the environmental cues whereby infection, chronic inflammation, and associated metabolic changes can repolarize their effector functions in the lungs. Several factors within the tumor microenvironment can re-educate AMs, resulting in tumor growth, and reducing immune checkpoint inhibitors (ICIs) efficacy in patients treated for non-small cell lung cancer …


Mortality Difference From Klebsiella Aerogenes Vs Enterobacter Cloacae Bloodstream Infections, Andrew Chou, Richard Sucgang, Richard J Hamill, Lynn Zechiedrich, Barbara W Trautner Jan 2023

Mortality Difference From Klebsiella Aerogenes Vs Enterobacter Cloacae Bloodstream Infections, Andrew Chou, Richard Sucgang, Richard J Hamill, Lynn Zechiedrich, Barbara W Trautner

Faculty, Staff and Students Publications

Members of the order Enterobacterales, including Escherichia coli , Klebsiella species and Enterobacter species, are important pathogens in healthcare-associated infections. Higher mortality has been reported from infections due to Klebsiella pneumoniae than from E. coli , but prior studies comparing Enterobacter aerogenes (recently renamed Klebsiella aerogenes ) bacteraemia and Enterobacter cloacae complex bacteraemia have yielded conflicting results regarding whether clinical outcomes differ. We found bacteraemia with K. aerogenes was independently associated with greater risk of 30-day mortality than bacteraemia with Enterobacter cloacae complex.

Bronchopulmonary dysplasia (BPD) is the most common lung disease of extreme prematurity, yet mechanisms that associate with or identify neonates with increased susceptibility for BPD are largely unknown. Combining artificial intelligence with gene expression data is a novel approach that may assist in better understanding mechanisms underpinning chronic lung disease and in stratifying patients at greater risk for BPD. The objective of this study is to develop an early peripheral blood transcriptomic signature that can predict preterm neonates at risk for developing BPD. Secondary analysis of whole blood microarray data from 97 very low birth weight neonates on day of …

A Population-Based Assessment Of Metastatic Hepatoblastoma In Texas Reveals Ethnic Disparities, Andres F Espinoza, Michael E Scheurer, Tiffany M Chambers, Sanjeev A Vasudevan, Philip J Lupo

Faculty, Staff and Students Publications

Background: Hepatoblastoma (HB) is the most common primary liver cancer in children with emerging evidence that incidence is increasing globally. While overall survival for low risk hepatoblastoma is >90%, children with metastatic disease have worse survival. As identifying factors associated with high-risk disease is critical for improving outcomes for these children, a need for a further understanding of the epidemiology of hepatoblastoma is warranted. Therefore, we conducted a population-based epidemiologic study of hepatoblastoma in Texas, a large state characterized by ethnic and geographic diversity.

Methods: Information on children diagnosed with hepatoblastoma at 0-19 years of age for the period of …

INTRODUCTION: Preterm infants have increased risk of impaired neurodevelopment to which reduced systemic levels of insulin-like growth factor 1 (IGF-1) in the weeks after birth may play a role. Hence, we hypothesized that postnatal IGF-1 supplementation would improve brain development in preterm pigs, used as a model for preterm infants.

METHODS: Preterm pigs delivered by cesarean section received recombinant human IGF-1/IGF binding protein-3 complex (rhIGF-1/rhIGFBP-3, 2.25 mg/kg/day) or vehicle from birth to postnatal day 19. Motor function and cognition were assessed by monitoring of in-cage and open field activities, balance beam test, gait parameters, novel object recognition and operant conditioning …

New probiotic strains and products, as well as expanding use of probiotics into vulnerable populations, warrants concise, and actionable recommendations on how to work toward their safe and effective use. The International Scientific Association for Probiotics and Prebiotics convened a meeting to discuss and produce evidence-based recommendations on potential acute and long-term risks, risks to vulnerable populations, the importance for probiotic product quality to match the needs of vulnerable populations, and the need for adverse event reporting related …


Cholestasis Impairs Gut Microbiota Development And Bile Salt Hydrolase Activity In Preterm Neonates, Lauren E Lynch, Amy B Hair, Krishnakant G Soni, Heeju Yang, Laura A Gollins, Monica Narvaez-Rivas, Kenneth D R Setchell, Geoffrey A Preidis Jan 2023

Cholestasis Impairs Gut Microbiota Development And Bile Salt Hydrolase Activity In Preterm Neonates, Lauren E Lynch, Amy B Hair, Krishnakant G Soni, Heeju Yang, Laura A Gollins, Monica Narvaez-Rivas, Kenneth D R Setchell, Geoffrey A Preidis

Faculty, Staff and Students Publications

Cholestasis refers to impaired bile flow from the liver to the intestine. In neonates, cholestasis causes poor growth and may progress to liver failure and death. Normal bile flow requires an intact liver-gut-microbiome axis, whereby liver-derived primary bile acids are transformed into secondary bile acids. Microbial bile salt hydrolase (BSH) enzymes are responsible for the first step, deconjugating glycine- and taurine-conjugated primary bile acids. Cholestatic neonates often are treated with the potent choleretic bile acid ursodeoxycholic acid (UDCA), although interactions between UDCA, gut microbes, and other bile acids are poorly understood. To gain insight into how the liver-gut-microbiome axis develops …
